Sentinel node biopsy often results in the identification and removal of multiple nodes as sentinel nodes, although most of these nodes could be non-sentinel nodes. This study investigated whether computed tomography-lymphography (CT-LG) can distinguish sentinel nodes from non-sentinel nodes and whether sentinel nodes identified by CT-LG can accurately stage the axilla in patients with breast cancer. This study included 184 patients with breast cancer and clinically negative nodes. Contrast agent was injected interstitially. The location of sentinel nodes was marked on the skin surface using a CT laser light navigator system. Lymph nodes located just under the marks were first removed as sentinel nodes. Then, all dyed nodes or all hot nodes were removed. The mean number of sentinel nodes identified by CT-LG was significantly lower than that of dyed and/or hot nodes removed (1.1 vs 1.8, p <0.0001). Twenty-three (12.5%) patients had ≥2 sentinel nodes identified by CT-LG removed, whereas 94 (51.1%) of patients had ≥2 dyed and/or hot nodes removed (p <0.0001). Pathological evaluation demonstrated that 47 (25.5%) of 184 patients had metastasis to at least one node. All 47 patients demonstrated metastases to at least one of the sentinel nodes identified by CT-LG. CT-LG can distinguish sentinel nodes from non-sentinel nodes, and sentinel nodes identified by CT-LG can accurately stage the axilla in patients with breast cancer. Successful identification of sentinel nodes using CT-LG may facilitate image-based diagnosis of metastasis, possibly leading to the omission of sentinel node biopsy

Full Text Available Abstract Background Primary Non-Hodgkin's Lymphoma (PHNL of the breast is a rare entity, while secondary involvement of the breast with diffuse disease of Non-Hodgkin's lymphoma (NHL is more common. However, PNHL is the most frequent haematopoietic tumour of the breast. Diagnostic criteria for PNHL of the breast are presence of technically adequate pathologic specimens, close association of mammary tissue and lymphomatous infiltrate, no prior diagnosis of an extarammamary lymphoma, and no evidence of concurrent widespread disease, except for ipsilateral axillary lymph nodes if concomitant with the primary lesion. Case presentation A 57-year-old woman was recalled because her screening mammograms revealed three separate lesions in her right breast and one in the left. Histology of the lesions confirmed lymphoma in one breast with ductal carcinoma in the other. Conclusion Most of reported cases in literature have been involving the right breast, and almost all the patients were females. NHLs of the breast typically present as unilateral mass; the frequency of bilateral disease at first presentation ranges from 5–25%. Our objective is to report a case of primary lymphoma of the breast involving both axillae with concomitant bilateral primary breast cancer which has not been reported yet to our best of knowledge in literature.

Patients and methods: From 1986 to 1993 we irradiated 655 patients with breast cancer after breast conserving surgery (BET). In all 144 cN1- and all 209 premenopausal cNO-patients axillary dissection was recommended. Of 302 postmenopausal cNO-patients 129 had breast surgery in our institution. In a total of 129 patients axillary dissection was replaced by irradiation (AxRT-group). They were compared with all 173 patients referred from other hospitals for irradiation after both breast conserving surgery and axillary dissection (AxOP-group). Dissected patients with gross tumor involvement of the axilla or less than eight nodes removed had additional axillary irradiation. Patients age, tumor size, vessel-, muscle- or skin invasion and grading were similar in both groups. However, in the AxRT-group there were more patients with negative hormon receptors, multifocal and medial sited tumors. Late complications after dissection and/or irradiation of the axilla were evaluated in 502 patients free of locoregional relapse and with a minimal follow up of 3 years (media 9,5 years). Results: After 5, 10 and 15 years tumor free survival rated were 90%, 82% and 79% in the AxOP-group vs 91%, 82% and 80% in the AxRT-group, respectively (p = 0.95). Overall survival (p = 0.98) local (p = 0.47) and axillary control (p = 0.12) were equal in both groups. However, serious problems like lymphedema of the arm, pain, mobility impairment occured in 26% patients following axillary dissection but only in 1% after axillary irradiation. No difference in late sequelae after axillary dissection with or without irradiation could be detected (26 vs 27%). (orig.)

The strategy of therapy of the axilla in early cancer. Surgery or radiotherapy

International Nuclear Information System (INIS)

Izuo, Masaru

1998-01-01

The therapy of the axillary lymph node in early breast cancer was assessed perspectively. Recently, axillary irradiation was carried out and compared with surgery. Radiotherapy was not evaluated more successful. To carry out in accordance with the present guide line, so called ''modern technique'' or ''modern dosage schedule'', radiotherapy of the axilla is effective as well as surgery. We have many agreements that the rate of incidence of complication associated with irradiation was decreased in accordance with ''modern technique''. It is reasonable to radiate additionally after the selection by the ''node sampling'' in the sense of decreasing unnecessary irradiation. But it is not sufficient in their reliability, it is hard to expect this method getting more popular than now. We cannot find any difference in the effect of the treatment itself between present dissection and radiotherapy. However we have many agreements that axillary dissection may give the information about n-stage, and the contribution to the suitable selection to the prognosis factor and adjuvant chemotherapy was not so less even in early cancer. Some early cancers (non-invasive carcinoma or micro carcinoma) will not need the axillary therapy. It is one of the options ''to combine mastectomy under local anesthesia and radiotherapy'' in close cooperation with the skilled radiologist. (K.H.) 120 refs

Successful Intra-Arterial Chemotherapy for Extramammary Paget’s Disease of the Axilla in a Patient with Parkinson’s Disease

Damascelli, Bruno; Ticha, Vladimira

2011-01-01

Extramammary Paget’s disease (EMPD) is a rare intraepithelial neoplasm occurring less frequently in men and even more rarely in the axilla. A 59-year-old man with severe Parkinson’s disease presented with axillary EMPD. The neurological comorbidity made treatment of the EMPD problematical and prompted us to propose locoregional intra-arterial chemotherapy in single short sessions. Two innovative chemotherapeutic macrocomplexes were used: doxorubicin incorporated in large liposomes and the taxane paclitaxel incorporated in albumin nanoparticles. A therapeutic response was seen right from the first treatment and was macroscopically close to complete after four cycles. Five months after the end of treatment the patient had minimal visible disease and had enjoyed a distinct improvement in quality of life, with no noteworthy complications related to the intra-arterial chemotherapy with percutaneous transfemoral catheterization.

To evaluate the role of preoperative axillary staging with ultrasound (US) and fine needle aspiration cytology (FNAC). Can we avoid intraoperative sentinel lymph node (SLN) examination, with an acceptable revision rate by preoperative staging? This study is based on the retrospective data of 336 patients that underwent US evaluation of the axilla as part of their staging. A FNAC biopsy was performed when abnormal lymph nodes were visualized. Patients with normal appearing nodes on US or a benign diagnostic biopsy had removal of the SLNs without intraoperative pathological examination. We calculated the sensitivity, specificity and accuracy of US/FNAC in predicting the necessity of an axillary lymphadenectomy. Subsequently we looked at the total cost and the operating time of 3 models. Model A is our study protocol. Model B is a theoretical protocol based on the findings of the Z0011 trial with only clinical preoperative staging and in Model C preoperative staging and intraoperative pathological examination were both theoretically done. sentinel node, staging, ultrasound, preoperative axillary staging, FNAC, axilla RESULTS: The sensitivity, specificity and accuracy are respectively 0.75 (0.66-0.82), 1.00 (0.99-1.00) and 0.92 (0.88-0.94). Only 26 out of 317 (8.2%) patients that successfully underwent staging needed a revision. The total cost of Model A was 1.58% cheaper than Model C and resulted in a decrease in operation time by 9,46%. The benefits compared with Model B were much smaller. Preoperative US/FNAC staging of the axillary lymph nodes can avoid intraoperative examination of the sentinel node with an acceptable revision rate. It saves tissue, reduces operating time and decreases healthcare costs in general. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Body odour of monozygotic human twins: a common pattern of odorant carboxylic acids released by a bacterial aminoacylase from axilla secretions contributing to an inherited body odour type.

Science.gov (United States)

Kuhn, Fabian; Natsch, Andreas

2009-04-06

It is currently not fully established whether human individuals have a genetically determined, individual-specific body odour. Volatile carboxylic acids are a key class of known human body odorants. They are released from glutamine conjugates secreted in axillary skin by a specific Nalpha-acyl-glutamine-aminoacylase present in skin bacteria. Here, we report a quantitative investigation of these odorant acids in 12 pairs of monozygotic twins. Axilla secretions were sampled twice and treated with the Nalpha-acyl-glutamine-aminoacylase. The released acids were analysed as their methyl esters with comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry detection. The pattern of the analytes was compared with distance analysis. The distance was lowest between samples of the right and the left axilla taken on the same day from the same individual. It was clearly greater if the same subject was sampled on different days, but this intra-individual distance between samples was only slightly lower than the distance between samples taken from two monozygotic twins. A much greater distance was observed when comparing unrelated individuals. By applying cluster and principal component analyses, a clear clustering of samples taken from one pair of monozygotic twins was also confirmed. In conclusion, the specific pattern of precursors for volatile carboxylic acids is subject to a day-to-day variation, but there is a strong genetic contribution. Therefore, humans have a genetically determined body odour type that is at least partly composed of these odorant acids.

Primary ectopic breast carcinoma is a rare disease and, at present, no specific guidelines on its diagnosis and treatment are available. The purpose of this article is to review the world literature in English on primary ectopic breast carcinoma located in the armpit and to offer guidelines for diagnosis and treatment. Data for this review were identified by searches of MEDLINE, PubMed, The Cochrane Library, ACNP (Italian catalogue of journals) and references from relevant articles using relevant search terms and data published in the previous reviews. Primary ectopic breast carcinoma of the axilla mostly affects women of over 40 (range 28-90 yrs) years of age. The most frequent histological diagnosis is invasive ductal carcinoma not otherwise specified (NOS) (72%). Because of its rareness, in most cases, the diagnosis is delayed for on average 40.5 months. This disease is rare, but a high level of suspicion for carcinoma is mandatory when confronted with a tumour in this area. Once diagnosed, patients should undergo staging, and prognostic and adjuvant treatment procedures identical to orthotopic breast carcinoma guidelines. There are some limitations for the staging. Loco-regional treatment, on indication, combined with endocrine therapy and/or chemotherapy seems the treatment of choice.

2015-06-01

The purpose of this study was to report on all cases in which posterior axilla sling traction (PAST) has been used to deliver cases of intractable shoulder dystocia and to describe a new method of shoulder rotation with the sling. A record of all published and known cases was collected that included information on preliminary obstetric techniques that were used and how the PAST technique was performed. Maternal outcomes that included maternal injury and length of hospital stay and fetal outcomes, which included birthweight, Apgar scores, nerve injuries, fractures, hospital stay, and outcome, were documented. We have recorded 19 cases where PAST has been used. In 5 cases, the babies had died in utero. Ten were assisted deliveries. PAST was successful in 18 cases. In one case, it was partially successful because it enabled delivery of the posterior shoulder with digital axillary traction. The most commonly used material was suction tubing. Once the posterior shoulder was delivered, the shoulder dystocia was resolved in all cases. Time from insertion to delivery was dystocia fail. Advantages are that it is easy to use (even by someone who has not seen it used previously), that the sling material is readily available, and that it is inserted quickly with 2 fingers. This is the first report of its use to rotate the posterior shoulder to the anterior position for delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

To present our experience in the therapeutic approach of the sentinel node biopsy (SNB) in patients with previous excision of the breast cancer, divided in non-palpable and palpable lesions, in comparison with time treatment and stagement of breast cancer. In the period 2001-2006, 138 patients with prior diagnostic excisional biopsy (96 non-palpable and 42 palpable breast cancer) and 328 without previous surgery (32 non-palpable; 296 palpable cancer) were treated. The combined technique ( 99m Tc-colloidal rhenium and isosulfan blue dye) was the approach for sentinel lymph node (SLN) detection. Axillary lymph node dissection (ALND) was completed only when the SLN was positive for metastasis or not located. Detection rate, if there was prior surgery, was 95% for non-palpable and 98% for palpable cancer, and 99% for one-time treatment group. Metastasis rate in the SLN was 15% in non-palpable cancer (14/91), significantly smaller than in palpable breast cancer (39% if prior surgery and 37% in one-time surgery). According to tumoral size, ALND metastasis rate was similar for T1 and T2 tumors (43-44%). In the follow-up of the groups with prior diagnostic biopsy or surgery of the breast cancer we have not found any false negative in the axilla. The detection of the SLN is also feasible in patients with previous surgery of breast cancer. Because SLN metastasis rates are significantly smaller in non-palpable lesions, the effort in screening programs for early detection of breast cancer and also in improving histopathological confirmation of malignancy with ultrasound or stereotactic guided core biopsies must continue.

Diode lasers are the most commonly used treatment modalities for unwanted hair reduction. Only a few controlled clinical trials but not a single randomized controlled trial (RCT) compared the impact of various laser parameters, especially radiant exposure, onto efficacy, tolerability and safety of laser hair reduction. To compare the safety, tolerability and mid-term efficacy of fixed, low and incremental radiant exposures of diode lasers (800 nm) for axillary hair removal, we conducted an intrapatient, left-to-right, patient- and assessor-blinded and controlled trial. Diode laser (800 nm) treatments were evaluated in 39 study participants (skin type II-III) with unwanted axillary hairs. Randomization and allocation to split axilla treatments were carried out by a web-based randomization tool. Six treatments were performed at 4- to 6-week intervals with study subjects blinded to the type of treatment. Final assessment of hair reduction was conducted 6 months after the last treatment by means of blinded 4-point clinical scale using photographs. The primary endpoint was reduction in hair growth, and secondary endpoints were patient-rated tolerability and satisfaction with the treatment, treatment-related pain and adverse effects. Excellent reduction in axillary hairs (≥ 76%) at 6-month follow-up visit after receiving fixed, low and incremental radiant exposure diode laser treatments was obtained in 59% and 67% of study participants respectively (Z value: 1.342, P = 0.180). Patients reported lower visual analogue scale (VAS) pain score on the fixed (4.26) than on the incremental radiant exposure side (5.64) (P diode laser treatments were less painful and better tolerated. © 2015 European Academy of Dermatology and Venereology.

The diagnosis and surgical management of screen-detected Ductal Carcinoma In Situ (DCIS) remains controversial including a range of axillary approaches and consequent morbidity. This study examined the management of the axilla in all patients with DCIS presenting through the United Kingdom National Health Service Breast Screening Programme (UK NHS BSP). Retrospective analysis of the UK NHS BSP identified 26,696 women initially diagnosed with DCIS over the 8 years 1 April 2003-31 March 2011. The final breast pathology of these women was upgraded to invasive ductal cancer in 5564 (20.8%) women or micro-invasive cancer in 1031 (3.9%) women. At first operation, 5290 (26.3%) of the 20,094 women who had a final post-operative diagnosis of DCIS only underwent axillary surgery (72.4% at the time of mastectomy, 23.8% breast conservation surgery, 3.8% axillary surgery alone). Performance of axillary surgery reflected increasing tumour size, micro-invasion or increasing nuclear grade for the final diagnosis of DCIS. More extensive nodal surgery was performed in those undergoing mastectomy; 10.8% of women had more than 8 nodes removed. Overall, 12.0% of women with invasive cancer, 1.7% with micro-invasion, and 0.2% with DCIS alone, were ultimately node positive. Improved pre-operative sampling of DCIS, axillary assessment by ultrasound with needle biopsy for suspected metastases, risk stratification for sentinel node biopsy (for high grade or extensive DCIS) and avoiding axillary clearance for a pre-operative diagnosis of DCIS alone should reduce unnecessary axillary surgery. Standards using such criteria for axillary surgery in screen-detected DCIS should be integrated into the NHS BSP. Crown Copyright © 2014. Published by Elsevier Ltd. All rights reserved.

Identifying an eschar in scrub typhus is useful for initiation of prompt and appropriate antibiotic therapy. The distribution of eschars in all children scrub typhus over a 5 year period is described. Of 431 children admitted with scrub typhus, eschars were present in 176 (40.8%) children with the following distribution: head, face and neck, 33 (19.1%); axillae, 37 (21%); chest and abdomen, 21 (11.9%); genitalia, inguinal region and buttocks, 58 (33%); back, 8 (4.5%); upper extremities, 13 (7.4%); and lower extremities, 5 (2.8%). The commonest sites of eschars were scrotum (27 of 106; 25.5%) and axillae (15 of 106; 14.2%) in males and axillae (22 of 70; 31.4%) and groin (16 of 70; 22.9%) in females. Eschars were seen within skin folds in 100 of 176 (56.8%) children. Children should be carefully examined for the presence of eschar especially in the skin folds of the genitalia, axillae and groin to make an early diagnosis of scrub typhus. © The Author [2016].

Purpose: Standard skin care instructions regarding the use of antiperspirants during radiotherapy to the breast varies across North America. Women have articulated that when instructed to not use antiperspirant, the potential for body odor is distressing. Historical practices and individual opinions have often guided practice in this field. The present study had 2 purposes. To evaluate whether the use of aluminum-based antiperspirant while receiving external beam radiotherapy for stage 0, I, or II breast cancer will increase axilla skin toxicity and to evaluate whether the use of antiperspirant during external beam radiotherapy improves quality of life. Methods: A total of 198 participants were randomized to either the experimental group (antiperspirant) or control group (standard care-wash only). The skin reactions in both groups were measured weekly and 2 weeks after treatment using the National Cancer Institute Common Toxicity Criteria Adverse Events, version 3, toxicity grading criteria. Both groups completed the Functional Assessment for Chronic Illness Therapy's questionnaire for the breast population quality of life assessment tool, with additional questions evaluating the effect of underarm antiperspirant use on quality of life before treatment, immediately after treatment, and 2 weeks after treatment during the study. Results: The skin reaction data were analyzed using the generalized estimating equation. No statistically significant difference was seen in the skin reaction between the 2 groups over time. The quality of life data also revealed no statistically significant difference between the 2 groups over time. Conclusions: Data analysis indicates that using antiperspirant routinely during external beam radiotherapy for Stage 0, I, or II breast cancer does not affect the intensity of the skin reaction or the self-reported quality of life. This evidence supports that in this particular population, there is no purpose to restrict these women from

Hydatid cyst of axilla masquerading as scrofuloderma

Directory of Open Access Journals (Sweden)

Shantilal M Sisodia

2013-01-01

Full Text Available Hydatid disease is an ancient endemic parasitic infestation caused by Echinococcus granulosus, which results in the formation of hydatid cysts in various parts of the body, the liver, and lungs being the most common sites. However, in 15% to 20% of the cases it may occur in unusual sites. We report a 25-year-old male patient who presented with clinical features similar to scrofuloderma in the axillary region but confirmed from histological examination to have hydatid cyst. This case highlights the uncommon site of hydatid cyst and unusual clinical and histopathological features along with the fact that it should be kept in differential diagnosis of nodules and sinuses in the axillary region. The treatment of choice is excision along with combination of albendazole and praziquantel.

The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis. Primary tumors may arise from any ectopic breast tissue. Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare. Two such cases were reported in this article. One was a 43-year-old Chinese female who exhibited bilateral breast cancer (invasive ductal carcinoma, not otherwise specified, IDC-NOS) and an accessory breast carcinoma (IDC-NOS) incidentally identified in her left axilla. The ectopic breast tissue in her right axilla presented with adenosis. The patient was surgically treated, followed by postoperative docetaxel epirubicin (TE) chemotherapy. The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified. The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen

Full Text Available Background: Nocardiosis is an uncommon but world-wide infection caused by several species of soil-borne aerobic bacteria belonging to the genus Nocardia. Primary cutaneous nocardiosis (PCN is an uncommon entity. It usually occurs among immunocompetent but occupationally predisposed individuals. Clinically, it can present as acute infection (abscess or cellulitis, mycetoma, or sporotrichoid infection [1]. Here we are reporting a case of PCN presented as mycetoma in axilla which is a rare site. Case History: The patient had extensive lesions in and around the axilla, which could be attributed to the fact that the patient, being an agriculturist, had been exposed to recurrent trauma while carrying firewood and soiled sacks. Single lesion initiated four years ago, progressed to multiple lesions with few healed scars. Despite the treatment in several hospitals, lesions recurred. The present patient was diagnosed as PCN caused by Nocardia brasiliensis and appropriately treated. Conclusion: Nocardia infection should be considered in the differential diagnosis of a supportive and granulomatous dermatitis that presents clinically as multiple discharging sinuses with papules and nodules in and around axilla apart from tuberculosis.

Aim: aim of this study is to magnify the lymphoscintigraphy examination by gamma probe with SPECT acquisition for very accurate detection of depth of axilla node in patients affected by melanoma. Methods: according to physiological peculiarities the lymphatic system plays a very important role and represents the most important barrier to neoplastic cells spreading. The 'sentinel node' is the first lymph node draining the affected area. The tendency for surgery is a 'preventive' axillary dissection, even in presence of a clinically negative examination. In fact a high percentage of clinically negative lymph node shows a positive histology (presence of metastatic cells). The nuclear medicine method for researching 'sentinel node' is represented by a regional lymphoscintigraphy with normal gamma camera with a large field of view followed by examination with gamma detecting probe and, in following day, controlled in operating room to confirm the presence of the node early identified. We have completed this protocol with SPECT examination of affected axilla by use of injected laboratory capillary around axilla to perform an exact investigation of node depth. Discussion: Our experience in 150 cases in 18 months shows 100% of axilla 'sentinel node' detection, 25 cases with positive histologic examination and subsequently axillary dissection. Conclusions: In conclusion the scintigraphic examination with lymphoscintigraphy represents a good tool for management of patient with melanoma and the use of ''targeting' with collimated SPECT represent a very aid for the surgeon in reduction time for detection and dissection of lymph node, with high reduction of anesthesia duration

Today, sentinel lymph node dissection (SLND) has replaced axillary lymph node dissection (ALND) as standard procedure for staging of the axilla in the treatment of breast cancer. SLND can accurately stage the axilla by removing on average only two lymph nodes. Only in case of metastatic spread...... was not significantly different in the two periods, whereas the proportion of patients with micrometastases increased significantly from 5.1% to 9.0%. However, the proportion of patients offered adjuvant systemic treatment due to positive nodal status as the only high-risk criterion did only increase from 7.8% to 8...

Bilateral Absence of Musculocutaneous Nerve: A Case Report

Detailed knowledge of course and distribution of nerves in the axilla and arm is very important in the management of nerve injuries particularly in case of their variations. Bilateral absence of the musculocutaneous nerve was found during routine dissection in a male cadaver. The dissected part was cleared to see the distribution of the muscles of the arm. The muscles of the flexor compartment were supplied by the median nerve, instead of the musculocutaneous nerve. The present case report of this anatomical variation of the nerves should help in management of nerve injuries in the axilla or the arm. PMID:25386419

axilla. In patients with no clinical signs of metastatic disease in the axilla, a SLN biopsy (SLNB) is performed. Assessment of metastases in the SLNB is done in a conventional microscope by manually observing a metastasis and measuring its size and/or counting the number of tumor cells. This is done...... essentially to categorize the type of metastases as macrometastases, micrometastases or isolated tumor cells, which is used to determine which treatment the breast cancer patient will benefit mostly from. The aim of this study was to evaluate whether digital image analysis can be applied as a screening tool...

Metaplastic breast cancer (MBC), characterized by admixed epithelial, squamous or mesenchymal elements, constitutes Statistical analyses evaluated axillary ultrasound (AUS), fine needle aspiration (FNA), and sentinel LN biopsy (SLNB) in association with LN status. Median tumor size was 2.7 cm and 76% were triple-negative. Twenty-three patients (56%) had preoperative AUS: 9 (39%) showed ≥1 suspicious LN, 6 proceeded to LN FNA and 3 were confirmed positive. Six patients had neoadjuvant chemotherapy, including 2 FNA LN+. Ten patients were LN+ at operation. Among 19 patients undergoing AUS and axillary surgery, AUS ± FNA sensitivity was 100% and specificity was 94%. LN positivity correlated with increasing tumor size, grade and angiolymphatic invasion. 16 patients recurred, 63% with distant disease (10/16) and one with isolated axillary disease after a negative SLNB not preceded by AUS. Overall SLNB accuracy was 96% (23/24), but absent preoperative AUS, 1/7 (14%) of SLNBs were falsely negative. Our study is the first to specifically address the performance and utility of AUS/FNA and SLNB for MBC patients. AUS/FNA at diagnosis followed by SLN surgery provided accurate nodal staging and critical prognostic information to inform treatment recommendations. We recommend this approach for axillary management of MBC patients.

The sequential action of a dipeptidase and a beta-lyase is required for the release of the human body odorant 3-methyl-3-sulfanylhexan-1-ol from a secreted Cys-Gly-(S) conjugate by Corynebacteria.

Human axillary odor is formed by the action of Corynebacteria on odorless axilla secretions. Sulfanylalkanols, 3-methyl-3-sulfanylhexan-1-ol in particular, form one key class of the odoriferous compounds. A conjugate with the dipeptide Cys-Gly has been reported as the secreted precursor for 3-methyl-3-sulfanylhexan-1-ol. Here, we confirm the Cys-Gly-(S) conjugate as the major precursor of this odorant, with lower levels of the Cys-(S) conjugate being present in axilla secretions. The enzymatic release of 3-methyl-3-sulfanylhexan-1-ol from the Cys-Gly-(S) conjugate by the axilla isolate Corynebacterium Ax20 was thus investigated. Cellular extracts of Ax20 released 3-methyl-3-sulfanylhexan-1-ol from the Cys-Gly-(S) conjugate and from the Cys-(S) conjugate, whereas the previously isolated C-S lyase of this bacterial strain was only able to cleave the Cys-(S) conjugate. o-Phenanthroline blocked the release from the Cys-Gly-(S) conjugate but did not affect cleavage of the Cys-(S) conjugate, indicating that in a first step, a metal-dependent dipeptidase hydrolyzes the Cys-Gly bond. This enzyme was purified by four chromatographic steps and gel electrophoresis, and the partial amino acid sequence was determined. The corresponding gene was cloned and expressed in Escherichia coli. It codes for a novel dipeptidase with a high affinity toward the Cys-Gly-(S) conjugate of 3-methyl-3-sulfanylhexan-1-ol. Co-incubating either the synthetic Cys-Gly-(S) conjugate or fresh axilla secretions with both the C-S lyase and the novel dipeptidase did release 3-methyl-3-sulfanylhexan-1-ol, proving that the sequential action of these two enzymes from the skin bacterium Corynebacterium Ax20 does release the odorant from the key secreted precursor.

Full Text Available INTRODUCTION: The relationship between skin-fold thickness and running performance has been investigated from 100 m to the marathon distance, except the half marathon distance. OBJECTIVE: To investigate whether anthropometry characteristics or training practices were related to race time in 42 recreational female half marathoners to determine the predictor variables of half-marathon race time and to inform future novice female half marathoners. METHODS: Observational field study at the 'Half Marathon Basel' in Switzerland. RESULTS: In the bivariate analysis, body mass (r = 0.60, body mass index (r = 0.48, body fat (r = 0.56, skin-fold at pectoral (r = 0.61, mid-axilla (r = 0.69, triceps (r = 0.49, subscapular (r = 0.61, abdominal (r = 0.59, suprailiac (r = 0.55 medial calf (r = 0.53 site, and speed of the training sessions (r = -0.68 correlated to race time. Mid-axilla skin-fold (p = 0.04 and speed of the training sessions (p = 0.0001 remained significant after multi-variate analysis. Race time in a half marathon might be predicted by the following equation (r² = 0.71: Race time (min = 166.7 + 1.7x (mid-axilla skin-fold, mm - 6.4x (speed in training, km/h. Running speed during training was related to skinfold thickness at mid-axilla (r = -0.31, subscapular (r = -0.38, abdominal (r = -0.44, suprailiacal (r = -0.41, the sum of eight skin-folds (r = -0.36 and percent body fat (r = -0.31. CONCLUSION: Anthropometric and training variables were related to half-marathon race time in recreational female runners. Skin-fold thicknesses at various upper body locations were related to training intensity. High running speed in training appears to be important for fast half-marathon race times and may reduce upper body skin-fold thicknesses in recreational female half marathoners.

A 20-year old patient who had been adequately treated for lymph node tuberculosis 14 years ago presented 1 week after giving birth to a healthy daughter. She complained about painful lumps in both axillae. During pregnancy the patient suffered from hyperemesis gravidarum, lost 6 kg of weight, and had night sweats. During the last three months of her pregnancy she had a deep vein thrombosis in her right lower leg. The clinical examination showed soft axillary lumps up to 3 cm. The lab showed the following pathological findings: blood sedimentation rate 51 mm/h, CRP 44.8 mg/l, LDH 221 U/l and INR 1.3 (indicating insufficient anticoagulation with phenprocoumon). The chest x-ray showed no infiltrate or indications of a past tuberculosis. A fine needle aspiration cytology was performed on an accessible node. Gram stain, Ziehl Neelsen stain, as well as the bacteriological cultures were all negative. An ultrasound examination of the axilla showed a thickened subcutis without a mass. Cytology showed lobular epithelium, consistent wih ductal mamma epithelium without atypical cells. The diagnosis of an accessory mamma tissue in both axillae was made. During the course of the following weeks the glands decreased in size and the patient was free of symptoms.

A 21-year-old man presented with a complaint of hoarseness as well as lesions along the eyelids and on his knees, elbows, and fingers. Hoarseness had developed in childhood, followed by lesions along the eyelids and on the elbows and fingers. He had developed lesions on the knees, feet, scrotum, penis, and axilla over the last 2 years. His parents were relatives, but nobody in the family showed similar features. His physical examination was normal. On dermatologic examination, there were beaded papules along the eyelids and small, yellow-white infiltrations on the tongue, buccal mucosa, palate, scrotum, and penis (Fig. 1). His tongue was firm and its mobility was limited. He also had infiltration of the frenulum (Fig. 2) and warty and hyperkeratotic papular and nodular lesions on the hands, knees, elbows (Fig. 3), and axilla. The laboratory findings and laryngoscopic examination were normal. Ophthalmologic, neurologic, and psychiatric examinations were also normal. Electroencephalogram (EEG), electromyogram (EMG), craniography, and cranial computed tomography (CT) scanning revealed no abnormality. The histopathologic examination of the skin biopsy specimens obtained from the axilla, elbow, and dorsum of the hand showed hyperkeratosis and periodic acid-Schiff-positive (PAS(+)) staining hyaline material around the dermal capillaries and sweat glands, and confirmed the diagnosis of lipoid proteinosis.

Lesions in nerves and plexus after radiotherapy

Apart from the typical, radiation-induced changes in the skin, common secondary findings were oedemas, radiation-induced ulceration, fibroses of the mediastinum and lungs, pleura adhesions, and osteoradionecroses. In one patient with radiogenic paresis of the plexus brachialis, irradiation of the spinal cord because of epidural metastases of a mammary carcinoma resulted in radiation myelopathy which was verified by laminectomy. Observations of radiogenic lesions of the plexus brachialis show that the usual site of the lesion in the vasomotoric nerve bundle is the axilla. The lesion is assumed to be caused mainly by an overlapping of the axillary, infraclavicular and supraclavicular fields of irradiation which results in a dose peak in the axilla.

Full Text Available Several studies have shown that a woman’s vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexual desire in men. Forty-five women and 115 men, all of them college students and unacquainted with each other, participated in the study. Female odors were collected on pads affixed to the axilla and on panty protectors both worn the entire night before experiments. Men provided five saliva samples, a basal one before the smelling procedure, and four more 15, 30, 60 and 75 min after exposure to odors. Immediately after smelling the odor source, men answered a questionnaire rating hedonic qualities of scents, and after providing the last saliva sample they answered questionnaire on sexual desire. We found that periovulatory axillary and vulvar odors increased testosterone and cortisol levels, with vulvar scents producing a more prolonged effect. Luteal axilla odors decreased testosterone and cortisol levels, while luteal vulva odors increased cortisol. Periovulatory axilla and vulva scents accounted for a general increase of interest in sex. These odors were also rated as more pleasant and familiar, while luteal vulvar odors were perceived as intense and unpleasant.

A radiolabeled monoclonal antibody (McAb) 6c6 was used to detect the metastatic lymph nodes of breast cancer externally and internally. 111 In was labeled to 6c6 by DTPA method. Iodogen method was used to label 131 I. The radiolabeled 6c6 was injected into the web space of each hand in seven women with breast cancer and one with benign breast tumor. The scans were positive in two axillae with palpable nodes and four with impalpable nodes. Pathologic examination later confirmed metastases in five of the axillae. Two axillae, one of them with palpable nodes, showed negative result, and here no tumor cells were found pathologically. Intraoperative metastatic lymph node detection with a hand-held gamma probe was carried out in six patients. 24 lymph nodes were measured with 17% (1/6) false negative and no false positive result (0/18), indicating that the result detected by the hand-held gamma probe presents the real radioactivity of the tissues being examined. There were 60 lymph nodes that were removed and detected again by well-shape detector after operation. The false positive rate was 14% (6/42), and the false negative rate was 11% (2/18), indicating that the radiolabeled McAb 6c6 could specifically combine with the metastatic lymph nodes of breast cancer in vivo

Irradiation of the lymphatics in the primary treatment of breast cancer

International Nuclear Information System (INIS)

Levitt, S.H.

1991-01-01

Irradiation is a local treatment which must be delivered to the appropriate areas, with appropriate dosage and careful attention to avoiding excess dosage to normal tissues. Despite the negative reports of meta analyses of randomized adjuvant radiation trials, there has recently been a renewed interest in local regional irradiation by a number of factors: Adjuvant chemotherapy fails to affect the incidence of locoregional recurrences in patients with four or more positive nodes; the benefits in prospective randomized and non randomized trials of large numbers of patients who were not treated with chemotherapy are well documented; analysis of the Cuzick meta analysis and the recent long term reports of the CRC and Manchester studies have demonstrated that they are not reliable. Locoregional recurrences following adjuvant chemotherapy alone are in the chest wall, internal memory and supraclavicular areas. We recommand no nodal irradiation in node negative patients and internal mammary and supraclavicular irradiation in node positive patients. However, irradiation to the axilla is indicated in patients in whom the axilla has not been dissected, the nodes are large and/or the tumor has extended from the nodes into the axilla. 50 Gy target dose is to be delivered in 1.8-2.0 Gy fractions and an additional 10 Gy boost to areas with possible tumor invasion in more advanced cancers.

Purpose: The purpose of this study was to describe regional nodal failure patterns in patients who had undergone mastectomy with axillary dissection to define subgroups of patients who might benefit from supplemental regional nodal radiation to the axilla or supraclavicular fossa/axillary apex. Methods and Materials: The cohort consisted of 1031 patients treated with mastectomy (including a level I-II axillary dissection) and doxorubicin-based systemic therapy without radiation on five clinical trials at M.D. Anderson Cancer Center. Patient records, including pathology reports, were retrospectively reviewed. All regional recurrences (with or without distant metastasis) were recorded. Median follow-up was 116 months (range, 6-262 months). Results: Twenty-one patients recurred within the low-mid axilla (10-year actuarial rate 3%). Of these, 16 were isolated regional failures (no chest wall failure). The risk of failure in the low-mid axilla was not significantly higher for patients with increasing numbers of involved nodes, increasing percentage of involved nodes, larger nodal size or gross extranodal extension. Only 3 of 100 patients with 20% involved axillary nodes, and the presence of gross extranodal extension (10-year actuarial rates 15%, 14%, and 19%, respectively, p 20% involved axillary nodes, or gross extranodal extension are at increased risk of failure in the supraclavicular fossa/axillary apex and should receive radiation to undissected regions in addition to the chest wall

In recent years repeat sentinel node (SN) biopsy has been proven to be feasible in local breast cancer recurrence (LBCR). However, in these patients SNs outside the ipsilateral axilla are frequently observed. This study evaluates the contribution of SPECT/CT for SN localization and surgical adjustment in LBCR patients. SN biopsy was performed in 122 LBCR patients (median age 60.5 years, range 24-87), enrolled from August 2006 to July 2015. Median disease-free time lapse was 109.5 months (range 9-365). Axillary lymph node dissection (ALND) had previously been performed in 55 patients, SN biopsy in 44, both techniques in 13 and fine-needle aspiration in 10. Primary breast cancer treatment included radiotherapy in 104 patients (85.3 %) and chemotherapy in 40 (32.8 %). Preoperative lymphatic mapping, using planar scintigraphy (PS) and SPECT/CT included report of SN location according to lymph node territory. In case of a territorial PS-SPECT/CT mismatch, surgery was adjusted according to SPECT/CT findings. SPECT/CT SN visualization rate was higher than PS (53.3 % vs. 43.4 %, p n.s.) with, in total, 19 additional SN (118 vs. 99, p n.s.). PS-SPECT/CT territory mismatch, found in 60 % (39/65) of patients with SN visualization, led to surgical adjustment in 21.3 % (26/122) of patients. The SN procedure was finally performed in 104 patients resulting in a 65.7 % surgical retrieval rate with a total of 132 removed SNs (1.86/patient). SN metastases were found in 17/71 patients (23.9 %), in 16 of them (94 %) in ipsilateral basins outside the axilla or in the contralateral axilla. Using SPECT/CT there is a trend to visualize more SNs in LBCR, providing at the same time important anatomical information to adjust intraoperative SN procedures. The addition of SPECT/CT to the standard imaging protocol may lead to better staging mainly in patients presenting drainage outside the ipsilateral axilla. (orig.)

2002-01-01

Full Text Available A 17 year old South Indian female born of consanguineous marriage presented with a widespread non-itchy eruption over scalp, face, below breasts and flexural aspects of limbs including axillae, inguinal regions and popliteal fossae since 3 months of age. The eruption consisted of individual small, flat, brownish black hyperkeratotic papules, which at some places, coalesced to from a reticulate pattern. Histopathological examination of biopsies from the axilla and forearm showed typical hyperkeratosis and papillomatosis without acanthosis. The dermis demonstrated a mild perivascular infiltrate. On the basis of the clinical and histopathological findings, a diagnosis of confluent and reticulate papillomatosis of Gourgerot and Carteaud was made. Partial response to doxycline in our case point towards this being a keratinization disorder where microflora may be playing an exacerbating rather than a primary role.

Nanoparticles in Sentinel Lymph Node Assessment in Breast Cancer

Full Text Available The modern management of the axilla in breast cancer relies on surgery for accurate staging of disease and identifying those patients at risk who would benefit from adjuvant chemotherapy. The introduction of sentinel lymph node biopsy has revolutionized axillary surgery, but still involves a surgical procedure with associated morbidity in many patients with no axillary involvement. Nanotechnology encompasses a broad spectrum of scientific specialities, of which nanomedicine is one. The potential use of dual-purpose nanoprobes could enable imaging the axilla simultaneous identification and treatment of metastatic disease. Whilst most applications of nanomedicine are still largely in the laboratory phase, some potential applications are currently undergoing clinical evaluation for translation from the bench to the bedside. This is an exciting new area of research where scientific research may become a reality.

Full text: Mammary lymphoscintigraphy using small volume (0.1-0.2 ml) peritumoral injections of 99 Tc m -antimony sulphide colloid provided a map of the lymph drainage of a breast cancer to its draining sentinel lymph nodes in 92 of 102 patients (over 90%). Non-migration of tracer is reduced by post-injection massage for 5 min but may occur especially if the lymphatics are blocked by metastases. Drainage included the axilla in 92%, internal mammary nodes in 43%, supraclavicular nodes in 12% and intramammary interval nodes in 10% of patients. One patient drained to an interpectoral node. Drainage across the centre-line of the breast occurred in 46% of patients but direct drainage to the contralateral side of the patient was not seen. Lymphatic drainage occurred to 1 node field in 52 patients, 2 node fields in 34 patients and 3 node fields in 6 patients, so that 43% of patients had multiple draining node fields. Drainage to non-axillary sites occurred in 51% of patients. In conclusion, mammary lymphoscintigraphy accurately maps sentinel node location in breast cancer. Approximately half of the patients will have sentinel nodes outside the axilla. To achieve complete lymph node staging in patients with breast cancer, it is logical to biopsy these non-axillary sentinel nodes as well as the sentinel nodes in the axilla. Failure to do so will potentially understage the node status in 50% of patients

Full Text Available Abstract Background Adolescent idiopathic scoliosis (AIS causes asymmetry of the torso, and this is often the primary concern of patients. Surgery aims to minimise the visual asymmetry. It is not clear how scoliosis makes the torso asymmetric or how scoliosis surgery changes that asymmetry when compared to the distribution of asymmetries seen in a non-scoliotic group of normal controls. Methods Surface topography images were captured for a group with AIS both pre-operatively and post-operatively. Identifiable points were compared between the images to identify the effects of AIS on the shape of the torso by looking at the relative heights and distances from the midline of the shoulders, axillae and waist in a two-dimensional coronal view. This was then compared to a previously reported group of normal non-scoliotic children to analyse whether surgery recreated normality. Results There were 172 pairs of images with 164 females and 8 males, mean age at pre-operative scan of 13.7 years. The normal group was 642 images (237 females and 405 males from 116 males and 79 females, mean age of 12.5 years. The curve patterns seen in the scoliotic group matched the patterns of a main thoracic curve (n = 146 and main thoracolumbar curve (n = 26. The asymmetries seen in both shoulders, axillae and waist were different between the two different types of curve. Across both groups, the shoulder asymmetry was less than that of the corresponding axillae. There was a statistically significant reduction in all asymmetries following surgery in the main thoracic group (p < 0.001. This was not seen in the main thoracolumbar group, thought to be due to the small sample size. In the main thoracic group, there were statistically significant differences in the asymmetries between the post-operative and normal groups in the shoulders and axillae (p < 0.001 but not the waist. Conclusions This paper demonstrates quantitatively the range of asymmetries seen

Partial breast irradiation (PBI) was designed in part to decrease overall treatment times associated with whole breast radiation therapy (WBRT). WBRT treats the entire breast and usually portions of the axilla. The goal of PBI is to treat a smaller volume of breast tissue in less time, focusing the dose around the lumpectomy cavity. The following is a case of a 64-year-old woman with early-stage breast cancer treated with PBI who failed regionally in the ipsilateral axilla. With our dosimetric analysis, we found that the entire area of this axillary failure would have likely received at least 45 Gy if WBRT had been used, enough to sterilize microscopic disease. With PBI, this area received a mean dose of only 2.8 Gy, which raises the possibility that this regional failure may have been prevented had WBRT been used instead of PBI

Deodorants are one of the most marketed types of cosmetics and are frequently reported as a cause of dermatitis, particularly among fragrance-sensitive persons. The aim of this study was to investigate the ability of deodorants, which had previously caused axillary dermatitis in fragrance......-mix-sensitive eczema patients, to provoke reactions on repeated open application tests on the upper arm and in the axillae, and to relate the findings to the content of fragrance-mix constituents in those deodorants. 14 eczema patients performed a 7-day use test with 1 or 2 deodorants that had caused a rash within...... the last 12 months. 2 applications per day were made in the axilla and simultaneously on a 25 cm2 area on the upper arm. A total of 20 deodorants were tested among the 14 patients. Afterwards, the deodorants were subjected to quantitative chemical analysis identifying constituents of the fragrance mix. 12...

Gastric Metastasis of Ectopic Breast Cancer Mimicking Axillary Metastasis of Primary Gastric Cancer

Directory of Open Access Journals (Sweden)

Selami Ilgaz Kayılıoğlu

2014-01-01

Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

Review of the role of the sentinel node biopsy in neoadjuvant chemotherapy in women with breast cancer and negative or positive axillary node at diagnosis.

Ruano Pérez, R; Rebollo Aguirre, A C; García-Talavera San Miguel, P; Díaz Expósito, R; Vidal-Sicart, S; Cordero García, J M; Carrera Salazar, D; Rioja Martín, M E

The role of the selective sentinel node biopsy (SNB) is increasing in relevance in breast cancer women with indication of neoadjuvant chemotherapy (NAC). The Radiosurgery Working Group of the SEMNIM is aware of the necessity of establishing the need for SNB before or after NAC, and also how to manage patients with axillary node-negative or node-positive. There is sufficient data to assess that the SNB with radioisotope techniques are feasible and safe in all these scenarios. An adequate axilla evaluation prior to surgery and the possibility of marking prior to NAC the nodes infiltrated must be the two main pillars to guarantee the success of the SNB. It has been shown that to incorporate the SNB in breast cancer women with indication of NAC increases the rate of a conservative treatment of the axilla that will be a clear benefit for these patients.

Full Text Available Hidradenocarcinoma is a rare aggressive form of cutaneous adnexal skin carcinoma originating from the sweat gland. Due to its low incidence, prognostic and treatment strategies are still being explored both for primary and advanced disease. This tumor most often presents as either solid or cystic appearing subcutaneous nodules, which may be associated with pruritus or ulceration. To date the mainstay of treatment for local disease has been surgical excision; however, the paucity of historical data available has shown that these tumors often behave aggressively with high rates of local recurrence, metastasis, and poor overall outcomes. There are few case reports describing the utility of radiation therapy in the treatment of hidradenocarcinoma. Herein, we present a case of metastatic apocrine hidradenocarcinoma in a 32-year-old Caucasian male. The patient initially underwent excisional biopsy which confirmed the diagnosis of poorly differentiated, highly infiltrative, apocrine hidradenocarcinoma. He received systemic chemotherapy for metastatic disease, followed by radiation therapy to areas of grossly palpable adenopathy. Prior to radiation therapy the patient had an enlarged hypermetabolic conglomerate of lymph nodes in the right axilla, and borderline enlarged low activity nodes within the left axilla. He received 3 cycles of chemotherapy followed by tamoxifen and radiation therapy (50.4 Gy in 28 fractions to areas of progressive disease in the bilateral axilla, lower neck, and axillary skin. Following treatment, the patient had complete resolution of skin nodules and improvement of his pruritus.

This case highlights the importance of recognition of the pattern of metastatic brachialplexopathy in breast cancer patients undergoing 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) for evaluation of recurrent disease.This pattern can be appreciated on maximum intensity projection (MIP) and coronal 18 F-FDG PET/CT images as a linear extension of tracer activity from superomedial aspect(supra/infraclavicular) to lateral aspect of the axilla closely related to the subclavian/axillary vessels). A 35-year-old woman diagnosed with infiltrating ductal carcinoma of the right breast had undergone six cycles of neoadjuvant chemotherapy, followed by wide local incision and radiotherapy. She had local recurrence, for which she was operated upon and given chemotherapy. She presented to her oncologist with pain and swelling in the right breast, nodules in the right axilla and restriction of movement of the right upper limb. The patient was referred for 18 F-FDG PET/CT to evaluate the extent of recurrent/metastatic disease. Whole-body PET/CT was acquired 1 h following the intravenous injection of 296 MBq of 18 F-FDG on a Biograph mCT scanner (Siemens). Evaluation of the MIP image revealed abnormal FDG accumulation at multiple sites in the thorax, along with a linear pattern of FDG uptake in the right lateral aspect of the upper chest (Fig. 1a, arrow). The coronal fused PET/CT image revealed a linear pattern of FDG uptake corresponding to an ill-defined mass extending from just behind the right clavicle into the right axilla (arrow). In addition, abnormal FDG accumulation was seen in a soft tissue density mass in the upper outer quadrant of the right breast, skin of the right breast laterally, both pectoral muscles (discrete foci) and in a few subpectoral nodes. Soft tissue nodular opacities in both lungs showed FDG accumulation suggestive of pulmonary metastasis (Fig. 1b, thick arrow). The patient was referred for magnetic

Full Text Available Background: In order to reduce the probability of later clinical involvement of the axilla and at establishing a sound basis for adjuvant treatment planning axillary dissection is an important operative procedure. So, partial axillary dissection has been applied to decrease the morbidity and postoperative axillary complications.Aim of the work was to study the reliability of partial axillary lymph node dissection in patients with breast carcinoma with clinically negative axilla. Methods: Eighteen patients underwent modified radical mastectomy, while the other two patients who were fulfilling the criteria for conservative breast surgery underwent lumpectomy. All patients did complete axillary lymph nodes dissection. Intraoperative leveling of the axilla was performed and level I axillary lymph nodes were identified according to their relation to pectoralis minor muscle; then they were subjected to intraoperative pathological examination by frozen section examination followed by complete axillary clearance. Then post operative histopathological examination of the tumor and all lymph nodes was done. Results: By intraoperative pathological examination; five patients (25% were found positive for malignant invasion, while 15 patients (75% were pathologically free. While paraffin section showed six patients (30% with malignant invasion, and 14 patients (70% were pathologically free. There was a false negative rate of 5% in level I axillary lymph nodes by intraoperative pathological examination which was positive for metastasis by paraffin section that revealed microinvasion in one lymph node out of 8 in level I. Only two cases out of 20 were found positive for metastasis in level II and III. Conclusion: Partial axillary lymph node dissection is a minimally invasive, feasible and sufficient technique that can predict the axillary lymph node status.

A bi-tangential technique is proposed to reduce undesired doses to the shoulder produced by standard tangential irradiation. A total of 6 patients affected by shoulder pain and reduced functional capacity after whole-breast irradiation were retrospectively analysed. The standard tangential plan used for treatment was compared with (1) a single bi-tangential plan where, to spare the shoulder, the lateral open tangent was split into two half-beams at isocentre, with the superior portion rotated by 10-20° medially with respect to the standard lateral beam; (2) a double bi-tangential plan, where both the tangential open beams were split. The planning target volume (PTV) coverage and the dose to the portion of muscles and axilla included in the standard tangential beams were compared. PTV95 % of standard plan (91.9 ± 3.8) was not significantly different from single bi-tangential plan (91.8 ± 3.4); a small but significant (p < 0.01) decrease was observed with the double bi-tangential plan (90.1 ± 3.7). A marked dose reduction to the muscle was produced by the single bi-tangential plan around 30-40 Gy. The application of the double bi-tangential technique further reduced the volume receiving around 20 Gy, but did not markedly affect the higher doses. The dose to the axilla was reduced both in the single and the double bi-tangential plans. The single bi-tangential technique would have been able to reduce the dose to shoulder and axilla, without compromising target coverage. This simple technique is valuable for irradiation after axillary lymph node dissection or in patients without dissection due to negative or low-volume sentinel lymph node disease.

To compare axillary involvement (N+) at initial staging in locally advanced breast cancer (LABC) with axillary lymphadenectomy histologic results after neoadjuvant chemotherapy treatment (NeoChemo). Retrospective study between November 2011 and September 2013 of LABC cases treated with neoadjuvant chemotherapy based on docetaxel (associated with trastuzumab in HER2 positive cases and carboplatin/adriamycin in HER2 negative cases). Those clinically or radiologically suspected cases of axillary involvement were histologically confirmed. When there was no suspicion of axillary involvement, sentinel lymph node radioguided biopsy (SLNRB) was performed using intradermal injection of (99m)Tc-nanocolloid albumin prior to neoadjuvant treatment. Axillary lymphadenectomy after NeoChemo was undertaken in all cases with positive axilla. Final pathologic response was classified as complete (pCR) when there was no evidence of tumoral disease and as non-pathologic complete response (no pCR) in the opposite case. A total of 346 patients treated with docetaxel were reviewed, identifying 105 LABC. Axillary involvement at initial staging was detected in 70 (67%) before starting NeoChemo. From these 70, 73% (n=51) were N+ (fine needle biopsy and/or biopsy) and the remaining 19 (27%) were occult N+ detected by SLNRB. Axillary lymphadenectomy detected pCR in 56% (39/70), increasing up to 84% pCR when initial N+ status was reached using SNLB. On the other hand, when N+ was detected using fine needle biopsy/lymph biopsy, pCR was only 45%. More than 50% of women affected by locally advanced breast cancer with tumoral axillary involvement at initial diagnosis present free metastatic axilla after therapeutic neoadjuvant chemotherapy effect. This increases up to almost 90% in case of occult metastatic axilla detected with sentinel node biopsy prior starting neoadjuvant chemotherapy. Copyright © 2014 Elsevier España, S.L.U. and SEMNIM.

Aim: The aim of this work was to evaluate the usefulness of lymphoscintigraphy using Tc 99m-dextran and a gamma detection probe, previous to as well as during radio guided biopsy, in patients with breast cancer and negative findings in axilla, respectively. Materials and Methods: 33 patients (range age 27-74 years) with breast cancer diagnosis, stage I and II, with tumors smaller than 5 cm in diameter and negative findings in axilla were evaluated from June 2000 to Dec 2001 to whom 37 MBq of Tc 99m-Dextran in a volume of 0.2 cc, was infiltrated intradermically, before the patient was placed under gamma camera and the sentinel node location was marked on skin. Biopsy was done using a combined method -gamma counter and vital blue dye- in thirty-three patients. Results: The sentinel node was visualized by lymphoscintigraphy in 32 patients (32/33) between five and twelve minutes after the radiopharmaceutical was injected. Sentinel node biopsy was done in an average time of sixteen minutes, proving that the skin markers were accurate in 90 % (30/33) of cases. Three false negative patients were found. In six patients the frozen biopsy was positive and confirmed using paraffin. The identification rate using both lymphoscintigraphy and radio guided biopsy was 97%. Conclusion: Lymphoscintigraphy with Tc-99m-dextran and surgical biopsy using the combined method could identify sentinel node in 97% of the patients with breast cancer and negative findings in axilla. The rate of false negative (9.3%) was according to expected. Lymphoscintigraphy was able to define the specific lymphatic drainage in each patient (32/33) and visualize the sentinel node to predict the lymphatic flow (32/33), which is specific in each patient. Skin marks were highly accurate in helping the surgeon with less operating time

Results of conservative surgery and radiation therapy for breast cancer

For stage I or II breast cancer, conservative surgery and radiation therapy are as effective as modified radical or radical mastectomy. In most cases, cosmetic considerations and the availability of therapy are the primary concerns. The extent of a surgical resection less than a mastectomy has not been a subject of a randomized trial and is controversial. It appears that removal of a quadrant of the breast for small lesions is safe but excessive. It may be possible to limit the breast resection to gross tumor removal for most patients while using wider resections for patients with an extensive intraductal component or for invasive lobular carcinoma. It also appears that excluding patients from breast conservation on the basis of positive margins on the first attempt at tumor excision may be unnecessarily restrictive. Although patients with an extensive intraductal component or invasive lobular carcinoma should have negative margins, it appears that a patient with predominantly invasive ductal carcinoma can be treated without re-excision if all gross tumor has been resected and there is no reason to suspect extensive microscopic disease. Patients with indeterminate margins should have a re-excision. Axillary dissection provides prognostic information and prevents progression of the disease within the axilla. Axillary dissections limited to level I will accurately identify a substantial number of patients who have pathologically positive but clinically negative nodes. When combined with radiation therapy to the axilla, a level I dissection results in a limited number of patients with progressive axillary disease. Patients with pathologically positive axillas and patients at particularly high risk for systemic disease because of the extent of axillary node involvement can be identified by dissections of levels I and II. 60 references.

Full Text Available Kimura′s disease is characterized by a triad of painless subcutaneous masses, eosinophilia in the peripheral blood and in tissues with marked increase in Serum Ig E. Angiolymphoid hyperplasia with eosinophilia (ALHE manifests with the presence of dermal papules and nodules. Unique clinical, histopathological, and biochemical findings are noted in these individual entities. A 32-year-female presented with multiple nodules in the axillae for 2 years. Peripheral smear showed eosinophilia with AEC of 6080. Histopathological examination showed features of overlap. Antinuclear antibody immunoflorescence was was negative. CD31, CD34, and FVIII were positive in vascular component. A CT chest revealed left axillary lymphadenopathy. The patient was treated with Cryotherapy and there was complete regression of skin lesions, with no recurrence after 1 year of follow-up. ALHE and KD are common in the head and neck region, but no reports of an overlap, presenting with lesions in the axillae are available to date, to the best of our knowledge. Response of skin lesions to cryotherapy is highlighted.

Cellular angiofibroma is a benign and rare tumor. It usually arises in middle-aged women and involves the vulva. Complete local excision of the tumor is the best cure, and, usually, there is no recurrence after surgery. We describe a 20-year-old woman with a painless, growing vulvar mass who presented about 3 years ago. Her past medical history was negative for oral contraceptives, tobacco, and alcohol, and there were no similar lesions in her family history. A physical examination revealed two masses on the right and the left labia majora and similar lesions on the left axilla and both breasts. An uncomplicated simple resection of the vulvar masses was done in the operating room. There was no evidence of recurrence 12 months after surgery. Histopathologic examination revealed that the findings were consistent with the diagnosis of the cellular angiofibroma. Based on our knowledge, this patient is the youngest case of vulvar angiofibroma. The lesions were large and symmetrical (on both labia majora), although they differed in size. Extravulvar (breast and axilla) lesions were also noteworthy in this patient.

Several groups have identified the characteristic axillary odorants and how they arrive on the skin surface, pre-formed, bound to water-soluble odorless precursors in apocrine secretions. In the current issue, Martin et al., (2010) describe the relationship between the production of axillary odorants and variants in the ABCC11 gene. Individuals who are homozygotic for a SNP (538G>A) were found to have significantly less of the characteristic axillary odorants than either individuals who were heterozygotic for this change or those who had the wild-type gene. The 538G>A SNP predominates in Asians who have nearly complete loss of typical body odor. ABCC11 is expressed and localized in apocrine sweat glands. These findings are remarkably similar to the ethnic distribution and expression patterns for apocrine apoD, a previously identified carrier of a characteristic axillary odorant.

Leiomyoma is a form of benign tumor originated in hypertrophy of the smooth muscles, which is most prevalent in the uterus and gastrointestinal tract. However, Leiomyoma originating from smooth muscle at the vessels lying on deep soft tissue is very rare. Our case was a rare case of leiomyoma originating from the axillary region, which was initially diagnosed as a fibroadenoma on radiological examination. The mass was separated from surrounding tissues and totally resected. Pathologically, hematoxylin-eosin-stained biopsy tissue showed the typical findings of leiomyoma. Postoperative follow-up observation was done for 1 year, without any complications or recurrence. Notably, a leiomyoma in the axillary region is difficult to differentiate from other benign or malignant tumors on preoperative radiological examinations such as ultrasonography or computed tomgraphy. Therefore, when an indefinite asymptomatic mass that is not lymphadenopathy or common benign tumor is identified in the axillary region, leiomyoma can be considered as one of the differential diagnoses.

BACKGROUND The 800 nm long-pulsed diode laser machine is safe and effective for permanent hair reduction. Traditionally, most long-pulsed diode lasers used for hair removal had a relatively small spot size. Recently, a long-pulsed diode laser with a large spot size and vacuum assisted suction handpiece was introduced. The treatment parameters of each type of handpiece differ. Short and long-term clinical efficacy, treatment associated pain, and patient satisfaction are important factors to be considered. This study aims to conduct a direct head to head comparison of both handpieces of the 800nm long-pulsed diode laser by evaluating long term hair reduction, treatment associated pain and patient satisfaction. Thirteen subjects were enrolled in this prospective, self-controlled, single-center study of axillary laser hair removal. The study involved 4 treatments using a long pulsed diode laser with a large spot size HS handpiece (single pass), HS handpiece (double pass), and a small spot size ET handpiece according to a randomized choice. The treatment sessions were done at 4-8 week intervals with follow up visits taken at 6 and 12 months after the last treatment session. Hair clearance and thickness analysis were assessed using macro hair count photographs taken at baseline visit, at each treatment session visit and at follow up visits. Other factors including pain, treatment duration, and patients' preference were secondary study endpoints. At 6 months follow up visits after receiving four laser treatments, there was statistically significant hair clearance in the three treatment arms with 66.1 % mean percentage hair reduction with the ET handpiece, 43.6% with the HSS (single pass) and 64.1 % with the HSD (double). However, at one year follow up, the results significantly varied from the 6 months follow up. The mean percentage hair reduction was 57.8% with the ET handpiece treated axillas (n=9), 16.5% with the HSS (single pass) handpiece treated axillas (n=7), and

This case highlights the importance of recognition of the pattern of metastatic brachialplexopathy in breast cancer patients undergoing {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) for evaluation of recurrent disease.This pattern can be appreciated on maximum intensity projection (MIP) and coronal {sup 18}F-FDG PET/CT images as a linear extension of tracer activity from superomedial aspect(supra/infraclavicular) to lateral aspect of the axilla closely related to the subclavian/axillary vessels). A 35-year-old woman diagnosed with infiltrating ductal carcinoma of the right breast had undergone six cycles of neoadjuvant chemotherapy, followed by wide local incision and radiotherapy. She had local recurrence, for which she was operated upon and given chemotherapy. She presented to her oncologist with pain and swelling in the right breast, nodules in the right axilla and restriction of movement of the right upper limb. The patient was referred for {sup 18}F-FDG PET/CT to evaluate the extent of recurrent/metastatic disease. Whole-body PET/CT was acquired 1 h following the intravenous injection of 296 MBq of {sup 18}F-FDG on a Biograph mCT scanner (Siemens). Evaluation of the MIP image revealed abnormal FDG accumulation at multiple sites in the thorax, along with a linear pattern of FDG uptake in the right lateral aspect of the upper chest (Fig. 1a, arrow). The coronal fused PET/CT image revealed a linear pattern of FDG uptake corresponding to an ill-defined mass extending from just behind the right clavicle into the right axilla (arrow). In addition, abnormal FDG accumulation was seen in a soft tissue density mass in the upper outer quadrant of the right breast, skin of the right breast laterally, both pectoral muscles (discrete foci) and in a few subpectoral nodes. Soft tissue nodular opacities in both lungs showed FDG accumulation suggestive of pulmonary metastasis (Fig. 1b, thick arrow). The patient was

Objective: To study the frequency of complications, particularly the lymphedema of the arm, after modified radical mastectomy in early breast cancer patients who have not been given post-operative radiotherapy to axilla. Design: Hospital based descriptive study. Results: Median age of these patients was 47 years with a range of 25-58 years. Majority of these patients were stage II (84%) and infiltrating ductal carcinoma was the most frequent type of cancer (88%). Fifty-six percent of these patients had high grade tumors. None of the patients received radiotherapy to axilla after modified radical mastectomy. Early complications documented from history and medical record revealed that seroma formation was the most frequent early complication seen after modified radical mastectomy (20%). Frequent late complications included anterior chest tightness (56%), shoulder dysfunction (36%), lymphedema (26%) and sensory loss (22%). Shoulder dysfunction included limited range of movement in all 18 patients. Gross multiple restrictions were seen in 11 (61.11%) of these patients. Conclusion: It is concluded from this study that lymphedema and shoulder dysfunction are the two major complications in patients of early breast cancer who have undergone modified radical mastectomy without post-operative axillary radiation.

Gupta A B

1995-01-01

Full Text Available PH- mapping of skin was made by measuring the skin surface pH in 61 normal Indian subjects (35M, 26F in the prepubertal age group at 21 different sites from scalp to sole at an ambient temperature 25-32C and a relative humidity 60-65%. The pH values at axilla, umbilicus, palm, fingerfolds, foot, sole, and cheek were found to be consistently higher than those at scalp, forehead, retroauricular folds, antecubital and popliteal fossae, anterior arm, anterior the mean pH of male skin appeared to be lower than that of female. The highest pH recorded was in axilla (5.98 for male, 6.00 for female, irrespective of sex. The lowest value however was in anterior neck (4.59 for male and in antecubital fossa (4.83 for female. While the origin of the skin pH is yet to be definitely known, it was observed that a high density of both sweat gland and bacteria flora leads to a high pH, and high concentration of sebaceous gland and of bacterial flora to a lower pH.

Reconstruction in extensive axillary Hidradenitis suppurativa with local fasciocutaneous V-Y advancement flaps

2006-01-01

Full Text Available We present our experience with the use of local fasciocutaneous V-Y advancement flaps in the reconstruction of 10 axillae in 6 patients for large defects following wide excision of long-standing Hidradenitis suppurativa of the axilla. The defects were closed with local V-Y subcutaneous island flaps. A single flap from the chest wall was sufficient for moderate defects. However, for larger defects, an additional flap was taken from the medial side of the ipsilateral arm. The donor defects could be closed primarily in all the patients. The local areas of the lateral chest wall and the medial side of the arm have a plentiful supply of cutaneous perforators and the flaps can be designed in a V-Y fashion without resorting to preoperative marking of the perforator. The flaps were freed sufficiently to allow adequate movement for closure of the defects. Although no attempt was made to identify the perforators specifically, many perforators were seen entering the flap. Some perforators can be safely divided to increase reach of the flap. All the flaps survived completely. A follow up of 2.5 years is presented.

Fibroadenoma in Axillary Supernumerary Breast in a 17-Year-Old Girl: Case Report.

Supernumerary breast or polymastia is a well documented anomaly of the breast, and commonly presents along the embryonic milk line extending between the axilla and groin. However, cases of polymastia have been recorded in the face, vulva, and perineum. The clinical significance of these anomalies include their susceptibility to inflammatory and malignant changes, and their association with other congenital anomalies of the urinary and cardiovascular systems. In this article we report a case of fibroadenoma that developed in the supernumerary breast of the right axilla in a 17-year-old girl. It is uncommon to find such palpable masses in young patients. Clinical and sonographic examination of both breasts revealed no abnormalities and no lymph nodes were detected in the axillae or the neck. No associated urologic or cardiovascular abnormalities were found, and the histopathological examination of the excisional biopsy samples showed a well-defined, capsulated intracanalicular type of fibroadenoma similar to that of eutopic mammary tissue. In this report, we describe a rare case of fibroadenoma in an accessory breast in a young woman. There are a fewer than 40 reports in the world about this subject, of which differential diagnoses include: cancer in axillary supernumerary breast, hidradenitis, axillary lymphadenomegaly, lipomas, anexial cutaneous neoplasia, cysts, and phylloides tumor. The combination of clinical examination, ultrasound, and cytology leads to adequate treatment, especially surgical. The diagnosis could be confused because of findings from cytology. In this case, because of the clinical and sonographic findings and multiple differential diagnosis, only the histopathological study was used to confirm the diagnosis. Despite its high sensitivity, cytology has low specificity and could create false positive results. However, atypical lesions can be seen in fibroadenomas, especially in younger patients, pregnant patients, and in patients who use hormonal

Full text: Introduction: Siliconoma, or silicone granuloma is the migration of silicon particles in the axillary lymph nodes, muscle and other non- ruptured or intact silicone implant. The latter is a relatively rare finding, and usually occurs in patients with extracapsular rupture of silicone prosthesis and has a typical ultrasound image. We present a case of a young woman with bilateral silicone prostheses placed 5 years ago, where in the right axilla are enlarged, structurally altered lymph nodes in the clinical and ultrasonography studies. Subsequent magnetic resonance examination shows intracapsular rupture ipsilateral silicone prosthesis and migration of silicon particles in the axillary lymph nodes. What you will learn: In this case we present twenty-three year old woman who reported pain and ‘swelling’ in the right axilla. The patient is with bilateral silicone prosthesis, she is not febrile and not reported other illness. After physical examination enlarged and tender lymph nodes in the right axilla was found. Several structurally altered and enlarged lymph nodes were visualized by ultrasound. These lymph nodes are hypoechogenic with obliterated fatty hilus. Due to the suspicion of silicone ‘extravasation’ in axillary lymph nodes, a magnetic resonance study of both mammary glands was performed. The images show intracapsular rupture of the right prosthesis without reliable data on silicone gel outside the fibrous capsule. Discussion: Siliconoma is a complication after plastic surgery of the breast and can affect both the axillary lymph nodes, and other lymphatic chains and also muscle and lung. Most frequently it occurs at damage of the extracapsular silicone prostheses. More rarely siliconoma occurs in siliconoma intracapsular damage, as in the presented case or in a silicone gel microbleed. Conclusion: The presence of siliconoma in axillary lymph nodes is relatively rare complication in plastic surgery of the breast. Methods of imaging diagnostic

Subcutaneous fat necrosis of the newborn (SCFN) is an uncommon, benign disorder found in full-term or post-mature neonates. It usually presents in neonates who have experienced perinatal difficulty such as asphyxia, peripheral hypoxemia, hypothermia, meconium aspiration or trauma. We present a newborn with abnormal findings on MRI and US within the axilla, neck, and abdominal walls that were pathologically proved via biopsy to be subcutaneous fat necrosis. (orig.)

Axillary silicone lymphadenopathy presenting with a lump and altered sensation in the breast: a case report

Directory of Open Access Journals (Sweden)

Adams Simon T

2009-03-01

Full Text Available Abstract Introduction Silicone lymphadenopathy is a rare but recognised complication of procedures involving the use of silicone. It has a poorly understood mechanism but is thought to occur following the transportation of silicone particles from silicone-containing prostheses to lymph nodes by macrophages. Case presentation We report of a case involving a 35-year-old woman who presented to the breast clinic with a breast lump and altered sensation below her left nipple 5 years after bilateral cosmetic breast augmentations. A small lump was detected inferior to the nipple but clinical examination and initial ultrasound investigation showed both implants to be intact. However, mammography and magnetic resonance imaging of both breasts revealed both intracapsular and extracapsular rupture of the left breast prosthesis. The patient went on to develop a flu-like illness and tender lumps in the left axilla and right mastoid regions. An excision biopsy of the left axillary lesion and replacement of the ruptured implant was performed. Subsequent histological analysis showed that the axillary lump was a lymph node containing large amounts of silicone. Conclusion The exclusion of malignancy remains the priority when dealing with lumps in the breast or axilla. Silicone lymphadenopathy should however be considered as a differential diagnosis in patients in whom silicone prostheses are present.

Full Text Available A 13-year-old girl was admitted to our department with a history of severe pain of her left axilla and fever. On physical examination, a block of lymph nodes in her left axilla, diffuse papular rash, and red-violet swelling of her supraclavicular and subclavian region were noted. Imaging investigations revealed left axillar and supraclavicular lymphadenopathy and a small nodular shade in the upper lobe of her left lung. A biopsy from an axillary lymph node established the diagnosis of anaplastic large cell lymphoma (ALCL, whereas DNA of Mycobacterium tuberculosis was detected by polymerase chain reaction (PCR in the same tissue biopsy. Patient was started on chemotherapy for ALCL and achieved remission of all initially involved fields. Nevertheless, two new nodular lesions were detected in the left lower lobe. Biopsy revealed granulomas, and PCR was positive for M. tuberculosis. Our patient received treatment with the combination of isoniazid and rifampin (12 months, pyrazinamide (the first 2 months, and maintenance chemotherapy for her ALCL for one year simultaneously. Four years later, she is disease free for both mycobacterial infection and lymphoma. We are reporting this successful management of mycobacterial infection in a patient with ALCL despite intensive chemotherapy that the patient received at the same time.

Full Text Available Alison E Hunter-Smith, Zenon Rayter Breast Surgery Unit, Bristol Breast Care Centre, North Bristol NHS Trust, Southmead Hospital, Westbury-on-Trym, Bristol, UK Abstract: Breast cancer is the most common cancer in women, worldwide, and 1,400 deaths per day are attributed to it. The success of national screening programs has seen breast cancers being diagnosed at an earlier stage. With conservative surgery to the breast demonstrating equivalent long-term outcomes, the last 10 years have seen a growing interest in the safety of less invasive management for the axilla in breast cancer patients. One-step nucleic acid amplification (OSNA is a validated, reliable, and efficient tool in identifying micro- and macro-metastases intraoperatively. It is the most widely used intraoperative analysis tool within the United Kingdom, and is employed by over 320 units across Europe and Asia. Recent evidence from the AMAROS, IBCSG 23-01, and ACOSOG Z0011 trials has changed surgical practice in managing the axilla of patients with breast cancer. We propose a clinical algorithm demonstrating the role of OSNA as an intraoperative analysis tool in today’s management of breast cancer as well as prospects for the future use of OSNA.

2015-03-01

Full Text Available Lipomas are the most common benign mesenchymal tumour. The solitary subcutaneous lipoma accounts for approximately one-quarter to one-half of all soft tissue tumours. The preferred locations include the trunk, shoulder, upper arm, and the neck. In this case report, we present a gigantic axillary lipoma weighing 23.35 kg. Due to the tumour mass and its long-term presence, the lipoma caused anatomical changes in the axilla making its removal challenging and difficult.

Body Site Is a More Determinant Factor than Human Population Diversity in the Healthy Skin Microbiome.

Guillermo I Perez Perez

Full Text Available We studied skin microbiota present in three skin sites (forearm, axilla, scalp in men from six ethnic groups living in New York City.Samples were obtained at baseline and after four days following use of neutral soap and stopping regular hygiene products, including shampoos and deodorants. DNA was extracted using the MoBio Power Lyzer kit and 16S rRNA gene sequences determined on the IIlumina MiSeq platform, using QIIME for analysis.Our analysis confirmed skin swabbing as a useful method for sampling different areas of the skin because DNA concentrations and number of sequences obtained across subject libraries were similar. We confirmed that skin location was the main factor determining the composition of bacterial communities. Alpha diversity, expressed as number of species observed, was greater in arm than on scalp or axilla in all studied groups. We observed an unexpected increase in α-diversity on arm, with similar tendency on scalp, in the South Asian group after subjects stopped using their regular shampoos and deodorants. Significant differences at phylum and genus levels were observed between subjects of the different ethnic origins at all skin sites.We conclude that ethnicity and particular soap and shampoo practices are secondary factors compared to the ecological zone of the human body in determining cutaneous microbiota composition.

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and paraaortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells. (author)

Dai, Yeqin; Xu, Ai-E; He, Junhua

2017-05-01

Axillary bromhidrosis has a strong negative effect on one's social life. A high success rate and few complications are criteria for a surgical treatment. The objective of this study was to evaluate a new surgical treatment modality for bromhidrosis: subcutaneous scissor with micropore. Twenty patients with bromhidrosis were treated. Patients were placed in a supine position with their treated arms abducted to 110°. After injection of 60 mL of tumescent solution into each axilla, one small incision was made at the middle axillary of the hair-bearing area. The whole hair-bearing skin was undermined at the level of the superficial fat to obtain adequate skin eversion. The flaps were everted to offer full exposure of the apocrine glands, and meticulous excision of each gland was performed. Both sides were punctured with scalpel. The micropore was used for drainage, and whose width was just 3 mm. Finally, the incisions were re-approximated, and bulky compressive dressings were applied to the area for 72 hours. Of the 40 axillae (20 patients), 34 (85.0%) showed excellent results, and six (15.0%) had good results. Malodor was significantly decreased. There were no serious complications. This technique can produce excellent results with a lower complication rate than most other surgical modalities and can be performed without costly equipment. © 2017 Wiley Periodicals, Inc.

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and paraaortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells. (author)

Objective: To evaluate the ability of detecting cerebral tumor by 99m Tc-HL91 in mice bearing glioblastoma G422. Methods: Six model mice underwent static whole body planar imagings at once and at 1,2,3,4,6,7,8 h postinjection of 99m Tc-HL91. Three mice each were killed at 4 h and 8 h, respectively. the tumor, blood and organs were removed, weighted and the radioactivity was measured. ROIs were drawn around tumor, head, contralateral axilla and chest in whole body planar images, and the radioactivity ratios of tumor to head (T/H), contralateral axilla (T/A) and chest (T/C) were calculated. Results: Increased tumor activity was identified in static whole body planar images since 1 h postinjection. At 2h postinjection, T/H, T/A and T/C were 2.93 +- 0.51, 4.86 +- 0.79 and 2.00 +- 0.35 respectively, which were significantly higher than those at once and at 1h postinjection (P 99m Tc-HL91 in tumor tissue of mice bearing glioblastoma G422 is increased and clearance rate is decreased. 99m Tc-HL91 imaging is suitable for glioblastoma at 2 h postinjection. It is appropriate to image tumors in head, neck, thorax, bone and soft tissues, but not in abdominal area

Full Text Available PURPOSE: To evaluate and present our initial results of a new marker (hemosiderin for mammary sentinel lymph node identification in an experimental model. METHODS: Skins mapped like a lymphatic duct draining to the axilla in patients submitted to breast biopsy, in our mastology service, stimulated us to try it in an animal model (female dogs. Our theory was that some blood derivate (hemosiderin was captured by macrophages and accessed the lymphatic ducts in direction to the axilla. Six female dogs of no defined race were studied. We injected 0,2 ml of technetium on both superior mammary glands. After ten minutes, a 2,5 ml solution of hemolized blood (hemosiderin from the own animal was injected in the subareolar lymphatic plexus on the left superior mammary gland and 2,5 ml of patent blue concomitantly and equally on the contralateral gland. Ten minutes after, incisions on both axilas were made to search, through the lymphatic mapping and a gamma probe, the sentinel lymph nodes. RESULTS: Seven brown sentinel lymph nodes were indentified and also radiomarked on the left axilla. Six blue sentinel lymph nodes were identified and also radiomarked on the right axilla. CONCLUSION: Preliminary studies of a potential new dye for sentinel lymph node identification are presented. It may be the change of the current use of the blue dyes and their severe side-effects on patients submitted to sentinel lymph node biopsies.OBJETIVO: Avaliar e apresentar resultados preliminares de um novo marcador (hemossiderina para a identificação de linfonodos sentinela mamários em um modelo experimental.

McCallum, S. J.; Welch, A. E.; Baker, L.

2001-08-01

In this paper, we describe the development of a new digital phantom designed for Monte Carlo simulations of breast cancer and particularly positron emission tomography (PET) imaging of the axillary lymph nodes. The phantom was based on data from the Visible Human Project female data set. The phantom covers the head-to-diaphragm regions; 17 major tissue types were segmented and 66 individual lymph nodes were identified. The authors have used the phantom in Monte Carlo simulations to model a reduced field-of-view PET imager based on two flat plate arrays placed on either side of the shoulder. Images used a simple single angle set of projections. The authors have conducted two preliminary studies: one modeling a single-frame PET acquisition 60 min after FDG injection and the other modeling a dynamic PET acquisition simulating four time frames after FDG injection. The dynamic results were processed into parametric images using the Patlak method and show the advantage to be gained by including the temporal information for legion detection. The authors' preliminary results indicate that the performance of such an imager forming projection images is not sufficient for axillary node PET imaging.

Maheswari, S Uma; Sampath, V; Ramesh, A

2018-01-01

Granulomatous slack skin syndrome is a rare variant of cutaneous T-cell lymphoma (mycosis fungoides). It is characterized clinically by redundant skin folds, which show a predilection towards flexural areas such as the axilla and the groin. Histologically, it shows a granulomatous T-cell infiltrate and loss of elastic tissue. It has an indolent but progressive course; and is usually refractory to treatment. We report a unique case of slack skin syndrome, sparing the classical sites with rapid and unusual involvement of non-intertriginous areas.

Fibrous hamartoma of infancy (FHI) is a rare, benign subcutaneous tumor occurring mainly before the age of 2 years. The most commonly reported locations of FHI are the extremities such as the shoulder or axilla. However, FHI arising in the genital area is extremely rare and has not been reported with correlated radiologic findings. In this case report, we present a case of 5-month-old male child diagnosed with FHI in the scrotum, with a focus on the correlation between the radiologic and pathologic findings.

Objective: The frequency and the anatomic distribution of involved regional nodes in recurrent and locally advanced breast cancer were analyzed, in order to evaluate the rational of conventional regional node radiation technique and provide evidence for target definition of breast cancer . Methods: Patients with recurrent or locally advanced breast cancer who were treated in our hospital from August 2003 to December 2009 were included in this study. 111 patients had contrast enhanced chest CT images of the whole regional nodes before treatment. The regional nodes were categorized into 8 anatomical substructures including medial and lateral supraclavicular nodes ( SC-M, SC-L), axilla nodes ( ALN )- I , II , III, infra clavicular nodes (IFN), Rotter's nodes (RN) and internal mammary nodes (IMN). The frequency of involvement and anatomical distribution of the involved nodes on CT images were analyzed. Results: A total of 111 patients were enrolled this study and 199 anatomical substructures with involved nodes were identified. The frequency of involvement were : SC-M 33, SC-L 21, ALN- I 30, ALN-II 25, ALN-III + IFN 35, RN 27, IMN 28. Supraclavicular region and axilla were the most frequently involved area (72.3%). The average depth of the SC-M and SC-L nodes was 33.48 mm ± 10. 57 mm and 45.62 mm ±20. 45 mm, and 51.5% and 71.4% of the SC-M and SC-L nodes were located more than 3 cm deep from the skin. The axilla nodes were located cranial and caudal to the axillary vein in 5 and 20 locally advanced breast cancer patients and in 64 and 28 patients who received prior axillary dissection. The majority of involved IMN was located within the first 3 intercostal spaces (26/28). The average distance between the center of involved IMN and chest skin was 24. 23 mm ± 10. 28 mm. The average distance between the center of involved IMN and midline of the body was 29. 38 mm ±6. 7 mm. The center of involved IMN was 6.19 mm ±5.73 mm lateral and 5.73 mm ± 4. 56 mm posterior to

Evaluation of the severity of clinical signs of cats with allergic skin diseases has used two scoring systems: Scoring Feline Allergic Dermatitis (SCORFAD) and the Feline Extent and Severity Index (FeDESI). The integrity of the cutaneous barrier can also be evaluated by measuring skin hydration. A correlation between the clinical score and skin hydration has been observed in humans and dogs with atopic dermatitis (AD). To demonstrate a correlation between the clinical score and skin hydration of cats affected with presumed AD. European short hair cats (n = 18): 11 females and seven males with a confirmed diagnosis of AD. SCORFAD and FeDESI scores were calculated and the measurements of skin hydration were assessed from seven body sites using corneometry. The correlation between the SCORFAD and FeDESI systems and skin hydration of each site, and the average skin hydration was calculated. There was a positive correlation between the SCORFAD score and skin hydration for the axilla, thorax and forelimb; for FeDESI and axilla and lumbar sites. There was a negative correlation between the FeDESI and skin hydration for the pinna (r = -0.47). Measurements of skin hydration could be a useful tool for the evaluation of allergic cats. There is limited evidence of any useful correlation between clinical scoring systems and measurements of hydration. The pinna may be a suitable region for the assessment of skin barrier function in normal and allergic cats. © 2017 ESVD and ACVD.

To predict the probability of lymphedema development in breast cancer patients in the early post-operation stage, we investigated the ability of quantitative lymphoscintigraphic assessment. This retrospective study included 201 patients without lymphedema after unilateral breast cancer surgery. Lymphoscintigraphy was performed between 4 and 8 weeks after surgery to evaluate the lymphatic system in the early postoperative stage. Quantitative lymphoscintigraphy was performed using four methods: ratio of radiopharmaceutical clearance rate of the affected to normal hand; ratio of radioactivity of the affected to normal hand; ratio of radiopharmaceutical uptake rate of the affected to normal axilla (RUA); and ratio of radioactivity of the affected to normal axilla (RRA). During a 1-year follow-up, patients with a circumferential interlimb difference of 2 cm at any measurement location and a 200-mL interlimb volume difference were diagnosed with lymphedema. We investigated the difference in quantitative lymphoscintigraphic assessment between the non-lymphedema and lymphedema groups. Quantitative lymphoscintigraphic assessment revealed that the RUA and RRA were significantly lower in the lymphedema group than in the non-lymphedema group. After adjusting the model for all significant variables (body mass index, N-stage, T-stage, type of surgery, and type of lymph node surgery), RRA was associated with lymphedema (odds ratio=0.14; 95% confidence interval, 0.04-0.46; p=0.001). In patients in the early postoperative stage after unilateral breast cancer surgery, quantitative lymphoscintigraphic assessment can be used to predict the probability of developing lymphedema.

Alexandrite and diode lasers are commonly used for hair removal. To date, the available spot sizes and repetition rates are defining factors in terms of penetration depth, treatment speed, and efficacy. Still, larger treatment areas and faster systems are desirable. To compare the efficacy, tolerability, and subject satisfaction of a continuously linear-scanning 808 nm diode laser with an alexandrite 755 nm laser for axillary hair removal. A total of 31 adults with skin types I-IV received 6 treatments at 4-week intervals with a 755 nm alexandrite laser (right axilla) and a continuously linear-scanning 808 nm diode laser (left axilla). Axillary hair density was assessed using a computerized hair detection system. There was a significant reduction in axillary hair after the 6th treatment (P lasers was not significant, but both were persistant at 18 months follow-up (left: hair clearance of 73.71%; right: hair clearance of 71.90%). Erythema and perifollicular edema were more common after alexandrite laser treatment, but all side effects were transient. While 62.50% of patients reported more pain in response to treatment with the new diode laser, all patients rated treatment with either laser tolerable. Treatment with either the alexandrite or the linear-scanning diode laser results in significant, comparable, persistent (at least 18 months) axillary hair reduction among individuals with skin types I-IV. © 2013 Wiley Periodicals, Inc.

Jacobsson, H.; Celsing, F.; Ingvar, M.; Stone-Elander, S.; Larsson, S.A.

1998-01-01

A diabetic male with severe autonomic neuropathy and recently discovered Hodgkin's disease demonstrated bilateral uptake of [2- 18 F]-2-fluoro-2-deoxy-d-glucose (FDG) in the axillary sweat glands during profuse sweating caused by hypoglycaemia at positron emission tomography examination. It is not yet clear whether the sweating interfered with the distribution of the radiopharmaceutical. Regardless of the cause or mechanism for the uptake, the finding is clinically relevant. A bilateral symmetrical accumulation of FDG in the axillae of a tumour patient does not necessarily indicate malignant involvement of the lymph nodes. (orig.)

Acanthosis nigricans (AN) is characterized by velvety, hyper pigmented, verrucosus, symmetric and occasionally pruritic plaques along with papillomatous lesions which have a special predilection for neck, axillae, groin, umbilicu and mucosal regions. Rarely, it presents as a para neoplastic syndrome and prompts a thorough search for an internal malignancy. We present here a case of malignant acanthosis nigricans seen in an elderly patient who was found to have underlying adenocarcinoma of the lower end of esophagus. After diagnosing associated malignancy, he was referred for further evaluation and subsequent surgical resection of tumour. (author)

2005-10-01

Regional silicone gel migration from a ruptured breast implant has been reported at different locations including the upper extremity, chest wall muscles, axilla and back. We report a patient who presented with an axillary mass that mimicked a regional recurrence 5 years after breast cancer reconstruction with a latissimus dorsi musculocutaneous flap and silicon gel expander-prosthesis. Surgical exploration revealed that the mass contained silicone gel around the port of the breast expander that had ruptured. The mass was confluent with an intracapsular silicone leak through a tract along the tube of the expander port.

Cosmetic Effect of Botulinum Toxin In Focal Hyperhydrosis

Directory of Open Access Journals (Sweden)

Jain S

2005-01-01

Full Text Available Hyperhydrosis of axillae, palm and sole is not a very uncommon problem. It leads to great embarrassment and considerable emotional stress to the individuals. Botulinum toxins prevent the release of acetylcholine at nerve terminals, therefore, reduces sweat secretion. Six patients of axillary and 4 patients of palmer and planter hyperhydrosis were treated with botulinum toxin. All patients experienced relatively satisfactory reduction of hyperhydrosis for period ranging between 4-7 months. No adverse effects were observed. Botulinum toxin therefore can be considered as an effective treatment in focal hyperhydrosis.

Purpose: The purpose of this study was to review management strategies with respect to systemic therapy and radiation treatment techniques, and to assess patient outcome (local regional control, distant metastases and overall survival) in breast cancer patients undergoing conservative surgery and radiation therapy (CS+RT) who had four or more lymph nodes involved at the time of diagnosis. Methods and Materials: Of 1,040 patients undergoing CS+RT at our institution prior to 12/89, 579 patients underwent axillary lymph node dissection, 167 of whom had positive nodes. Fifty-one of these patients had four or more positive lymph nodes involved and serve as the patient population base for this study. The median age was 51 years (range 33-80), median number of nodes sampled was 16, and the median number of positive nodes was 7 (range 4-21). All patients received radiation therapy to the intact breast using tangential fields with electron beam boost to a total median dose of 6400 cGy. The majority of patients received regional nodal RT as follows: 40 patients received RT to the supraclav without axilla to a median dose of 4600 cGy, 10 patients received radiation to the supraclav and axilla to a median dose of 4600 cGy. Thirty-five of the 51 patients received a separate internal mammary port with a mixed beam of photons and electrons. One patient received radiation to the tangents alone without regional nodal irradiation. Adjuvant systemic therapy was employed in 49 of the 51 patients (96%) with 36 patients receiving chemotherapy (CTX) alone, six receiving tamoxifen alone and nine patients receiving both CTX and tamoxifen. Of 45 patients receiving CTX, 12 (27%) received RT prior to CTX, 22 (48%) received RT concurrently with CTX, 6 (14%) received RT sandwiched with CTX and 5 (11%) received RT following all systemic CTX (RT delay > 16 weeks). Results: As of 12/94, there have been 18 distant relapses, two nodal relapses and five breast relapses resulting in a 10-year distant

Post-transplantation lymphoproliferative disorders (PTLDs) are a heterogeneous group of diseases that represent serious complications following immunosuppressive therapy for solid organ or hematopoietic-cell recipients. In contrast to B-cell PTLD, T-cell PTLD is less frequent and is not usually associated with Epstein Barr Virus infection. Moreover, to our knowledge, isolated T-cell PTLD involving the breast is extremely rare and this condition has never been reported previously in the literature. Herein, we report a rare case of isolated T-cell PTLD of the breast that occurred after a patient had been treated for allogeneic peripheral blood stem cell transplantation due to acute myeloblastic leukemia.

Commonly affected sites include the axilla, groin, perineum and perianal areas. In this study we performed a literature review on the surgical methods for HS and describe an innovative technique for reconstructing axilla HS using an inner-arm transposition flap.MethodsWe reviewed all cases (5 cases from 4 patients of transposition flap reconstruction performed by the senior author at a single London tertiary hospital from 2008–2013. Patient related outcome measures were collected using the Derriford appearance scale (DAS 24 and a study specific questionnaire.ResultsAll patients were satisfied with their final result. One out of five cases had a complication but did not result in flap failure. There is no disease recurrence to date. DAS 24 scores collected demonstrated acceptable postoperative distress that did not deviate far from the norm tables while study specific questionnaire reveal desirable outcomes.ConclusionsWe have managed to achieve our aim through the use of the innovative inner-arm transposition flap. Our study hopes to provide an additional technique for axillary reconstruction. This technique offers the effective concealment of scars with the benefit of tightening of the arm tissue producing ‘brachioplasty like’ effects. All things considered it would be reasonable to conclude the innovative flap technique is a reliable, effective, and simple method that results in multiple benefits.

The measurement of transepidermal water loss (TEWL) is one of the parameters that can be used to assess skin barrier function. The variability and reliability of TEWL measurements in dogs have been controversial, and the hair coat has been considered as one of the factors that may cause variation of TEWL values. The aims of the study were to establish a suitable procedure for measuring feline TEWL, to evaluate the influence of hair coat on TEWL measurements and to assess variations of TEWL at different anatomical sites. Transepidermal water loss was measured using a closed-chamber evaporimeter, the VapoMeter(®). We compared three adjacent sites in the groin area of 10 clinically normal, domestic short hair cats. One site was unclipped, the second was trimmed with scissors and the third was shaved using electric clippers. Values of TEWL were obtained for 48 h after trimming with scissors and clippers. Five sites were clipped (upper back, lumbar back, lateral thigh, axillae and groin), and the TEWL was measured. The mean and SD of TEWL values of the clipper-trimmed site were the smallest, followed in order by the site trimmed with scissors and the unclipped site. The TEWL values were statistically constant in the clipper-trimmed site, while the values in the unclipped sites were not. There was no statistically significant difference in TEWL values between all of the anatomical sites except for the axillae. Hair clipping of sites with electric clippers is recommended for TEWL measurement in cats. © 2013 ESVD and ACVD.

Axillary ultrasound (AUS) with fine-needle aspiration (FNA) biopsy of abnormal lymph nodes is important for pre-operative staging and planning the surgical management of the axilla. Invasive lobular carcinoma (ILC) metastases are thought to be difficult to detect because the cells are small and on cytology resemble lymphocytes. To investigate this we directly compared the sensitivity of pre-operative axillary staging between ILC and invasive ductal carcinoma (IDC). Consecutive patients that presented in a single breast unit with pure IDC between April 2005 and December 2006 and pure ILC between January 2008 and December 2012 were retrospectively identified from pathology records. Pre-operative axillary ultrasound and FNA biopsy results were compared with post-operative histopathology from the sentinel node biopsy (SNB) or axillary lymph node dissection (ALND). A total of 275 and 142 axillae were identified in the IDC and ILC groups respectively. In the node positive patients there was no significant difference in the sensitivity of AUS (IDC vs. ILC; 58.7% vs. 52.8%). However, there was a significant difference in the sensitivity of ultrasound-guided FNA biopsy of abnormal nodes (IDC vs. ILC; 98.4% vs. 53.6%; p < 0.001). AUS has comparative sensitivities between IDC and ILC populations. In contrast, FNA biopsy of abnormal axillary nodes is clearly less sensitive in the ILC group. In these patients, who have abnormal AUS, we suggest that a core biopsy is required to improve the pre-operative staging and prevent unnecessary surgical procedures. Copyright © 2014 Elsevier Ltd.

Aims: To compare the performance of ultrasound elastography with conventional ultrasound in the assessment of axillary lymph nodes in suspected breast cancer and whether ultrasound elastography as an adjunct to conventional ultrasound can increase the sensitivity of conventional ultrasound used alone. Materials and methods: Fifty symptomatic women with a sonographic suspicion for breast cancer underwent ultrasound elastography of the ipsilateral axilla concurrent with conventional ultrasound being performed as part of triple assessment. Elastograms were visually scored, strain measurements calculated and node area and perimeter measurements taken. Theoretical biopsy cut points were selected. The sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV) were calculated and receiver operating characteristic (ROC) analysis was performed and compared for elastograms and conventional ultrasound images with surgical histology as the reference standard. Results: The mean age of the women was 57 years. Twenty-nine out of 50 of the nodes were histologically negative on surgical histology and 21 were positive. The sensitivity, specificity, PPV, and NPV for conventional ultrasound were 76, 78, 70, and 81%, respectively; 90, 86, 83, and 93%, respectively, for visual ultrasound elastography; and for strain scoring, 100, 48, 58 and 100%, respectively. There was no significant difference between any of the node measurements Conclusions: Initial experience with ultrasound elastography of axillary lymph nodes, showed that it is more sensitive than conventional ultrasound in detecting abnormal nodes in the axilla in cases of suspected breast cancer. The specificity remained acceptable and ultrasound elastography used as an adjunct to conventional ultrasound has the potential to improve the performance of conventional ultrasound alone.

To expand current knowledge on the canine omental vasculature and refine the existing lengthening technique of the canine omentum. Ex vivo study. Canine cadavers (n=20). In 10 canine cadavers the omental arteries were mapped using intravascular latex injection and these results were used to create an omental pedicle flap based on the splenic artery in 10 additional cadavers. The operating range of the flap was recorded with particular attention to the main regions of interest for omental transposition in dogs (axillary and inguinal regions). The superficial and deep omental leaves were each predominantly supplied by a left and a right marginal omental artery that anastomosed near the caudal omental border into a superficial and a deep omental arch, respectively. Anastomoses between arteries of the superficial and the deep omental leaves were weak and inconsistent, except for 1 anastomosis that was found in 8 of 10 dogs. By transposing the intact omentum, the right axilla could be reached in 3 dogs, both axillae in 1 dog, and both groins in all cadavers. In all cases, the omental pedicle reached to and beyond the axillary and inguinal regions. By unfolding the pedicle leaves, the width of the pedicle tip could be doubled. When lengthening the omentum is necessary to reach extra-abdominal structures, the omental pedicle flap based on the splenic artery appears to preserve the omental vascular supply. These observations warrant further clinical trials to evaluate this new omtental flap technique in vivo. © Copyright 2016 by The American College of Veterinary Surgeons.

Objective: To determine the accuracy of SLN biopsy for the assessment of auxiliary status, and prognostic markers leading to lymphatic metastasis in patients with early (T1) breast cancer. Design: Cross-sectional study. Place and Duration of Study: Department of Surgery, Teaching and Research Hospital. Between January 2000 and August 2004. Patients and Methods: SLN mapping by blue dye method was performed on 39 patients with T1 breast carcinoma. SLNs, level 1 and 2 auxiliary nodes were dissected and excised. The size, pathologic features of the primary tumor, SLNs and other auxiliary nodes, and hormone receptors were evaluated by histopathologic examination. The rate of SLNs and non SLNs involvement, and demographic, clinical and pathologic risk factors leading to nodal metastasis were established. The diagnostic accuracy of SLN for auxiliary status was calculated. Results: SLNs were identified in 37 (95%) patients. The axilla had metastasis in 11 (28%) patients. Malignant cells involved SLNs in 8 patients. Non-SLNs had metastasis in 3 patients without SLN involvement. The sensitivity, specificity and accuracy of SLN biopsy for predicting auxiliary status was calculated as 73%, 100% and 92% respectively. Four of 5 patients T1c tumors (p=0.14) and lymphovascular invasion (p=0.0004). Conclusion: SLN biopsy with high diagnostic accuracy may prevent unnecessary disection of the axilla in the majority of patients with early (T1) breast carcinoma. Some risk factors as pre-menopausal status, absence of hormone receptors, and presence of lymphovascular invasion must be taken into account as important determinant of non-SLNs metastasis. (author)

Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

The intravascular papillary endothelial hyperplasia (IPEH/Masson's tumor) is a rare benign tumor of the skin and subcutaneous vessels. We report, in four pediatric cases, clinical presentation, care (diagnostic and surgical) of Masson's tumor in children. Two boys (two years) and two girls (four and six years) showed a pain subcutaneous tumor (one to five centimeters). They were in the transverse abdominal muscle, between two metatarsals, at the front of thigh and in the axilla. Imaging performed (MRI, Doppler ultrasound) evoked either a hematoma, a lymphangioma or hemangioma. The indication for removal was selected from pain and/or parental concern. The diagnosis was histologically. A lesion persisted in residual form (incomplete initial resection), and is currently not scalable for eleven years. This tumor is characterized by excessive proliferation and papillary endothelial cells in the vessels, following a thrombotic event. It is found mainly in adults (no specific age), and preferentially localizes in the face and limbs. The clinical differential diagnosis of this tumor is angiosarcoma. The imagery has not allowed in our series to diagnose but still essential to eliminate differential diagnoses. Only surgical excision with histological examination can differentiate. Our study emphasizes the possibility of pediatric cases with two cases of unusual locations (abdominal and axilla). Clinical presentations we met, now lead us to direct our histologist looking for a Masson tumor in any child with a subcutaneous tumor and/or intramuscular pain, sudden onset, and vascular appearance (after excluding an arteriovenous malformation).

Marquez, Juan Camilo; Acosta, Mauricio Fernando; Uribe Jorge Ricardo

2009-01-01

We report a case of vascular thoracic outlet syndrome in a young man, diagnosed with upper limb arteriography, leading to repeated arterio-arterial emboli originating from a post-stenotic subclavian artery aneurysm. It is of our interest due to its low incidence and the small number of cases reported that have been diagnosed by arteriography. The thoracic outlet is the path through which vascular and neural structures goes from the neck to the axilla, and it has three anatomical strictures, that when pronounced, can compress the brachial plexus or subclavian vessels, leading to different symptoms and signs.

Excess radiation to the skin during external beam megavoltage radiation therapy has reportedly caused excessive erythema in patients treated with the Clinac 4 linear accelerator on sloping surfaces, but not for similar treatments with cobalt-60. Doses at the epidermal level were measured under geometries simulating sloping surfaces for a Clinac 4 and an Eldorado 8 cobalt-60 teletherapy machine. For equal doses to the axilla, doses to the epidermal layer were similar. When the tumor dose was calculated for the mediastinum, the dose to the skin in the axillary region was 12% higher for the Clinac 4

Gynecomastia is a benign enlargement of male breast, common in adolescents and adults. To treat this deformity, we have been carrying out liposuction through small cutaneous incisions placed in the axilla and on the sternum. If necessary, we performed a surgical excision of glandular tissue through a periareolar incision. From 1995, we started to perform surgical excision of glandular tissue, if necessary, through the small incisions made for liposuction, thus avoiding the periareolar scars. We describe our experience with this technique, which we believe excellent for the correction of glandular and fatty glandular gynecomastia, obtaining excellent esthetic results and minimal local scarring.

Full Text Available We present a case demonstrating the diagnostic work-up and follow-up of a patient with acute Epstein-Barr virus (EBV infection in which the clinical picture and imaging on 18F-FDG PET/CT mimicked malignant lymphoma. Follow-up 18F-FDG PET/CT scan in the patient performed 7 weeks after the abnormal scan revealed complete resolution of the metabolically active disease in the neck, axillas, lung hili, and spleen. This case highlights inflammation as one of the most well established false positives when interpreting 18F-FDG PET/CT scans.

Full Text Available Primary angiosarcoma of the breast is an uncommon, aggressive neoplasm with an unknown etiology. In this paper, we present a case of a 28 year woman who initially developed primary angiosarcoma of the breast and ovary, followed twenty months later by metastasis to the axilla. Only a few cases of primary angiosarcomas of the breast have reported metastasis to the ovary. Of these cases, all had ovarian metastasis at presentation or shortly after initial diagnosis. This particular case is unusual, the metastases occurred two years following treatment of the primary tumor. This paper will address possible factors contributing to metastasis.

The relationship between skin-fold thickness and running has been investigated in distances ranging from 100 m to the marathon distance (42.195 km), with the exclusion of the half-marathon distance (21.0975 km). We investigated the association between anthropometric variables, prerace experience, and training variables with race time in 42 recreational, nonprofessional, female half-marathon runners using bi- and multivariate analysis. Body weight (r, 0.60); body mass index (r, 0.48); body fat percentage (r, 0.56); pectoral (r, 0.61), mid-axilla (r, 0.69), triceps (r, 0.49), subscapular (r, 0.61), abdominal (r, 0.59), suprailiac (r, 0.55), and medial calf (r, 0.53) skin-fold thickness; mean speed of the training sessions (r, -0.68); and personal best time in a half-marathon (r, 0.69) correlated with race time after bivariate analysis. Body weight (P = 0.0054), pectoral skin-fold thickness (P = 0.0068), and mean speed of the training sessions (P = 0.0041) remained significant after multivariate analysis. Mean running speed during training was related to mid-axilla (r, -0.31), subscapular (r, -0.38), abdominal (r, -0.44), and suprailiac (r, -0.41) skin-fold thickness, the sum of 8 skin-fold thicknesses (r, -0.36); and percent body fat (r, -0.31). It was determined that variables of both anthropometry and training were related to half-marathon race time, and that skin-fold thicknesses were associated with running speed during training. For practical applications, high running speed during training (as opposed to extensive training) may both reduce upper-body skin-fold thicknesses and improve race performance in recreational female half-marathon runners.

Contraindications of sentinel lymph node biopsy: Áre there any really?

Directory of Open Access Journals (Sweden)

Zografos George

2007-01-01

Full Text Available Abstract Background One of the most exciting and talked about new surgical techniques in breast cancer surgery is the sentinel lymph node biopsy. It is an alternative procedure to standard axillary lymph node dissection, which makes possible less invasive surgery and side effects for patients with early breast cancer that wouldn't benefit further from axillary lymph node clearance. Sentinel lymph node biopsy helps to accurately evaluate the status of the axilla and the extent of disease, but also determines appropriate adjuvant treatment and long-term follow-up. However, like all surgical procedures, the sentinel lymph node biopsy is not appropriate for each and every patient. Methods In this article we review the absolute and relative contraindications of the procedure in respect to clinically positive axilla, neoadjuvant therapy, tumor size, multicentric and multifocal disease, in situ carcinoma, pregnancy, age, body-mass index, allergies to dye and/or radio colloid and prior breast and/or axillary surgery. Results Certain conditions involving host factors and tumor biologic characteristics may have a negative impact on the success rate and accuracy of the procedure. The overall fraction of patients unsuitable or with multiple risk factors that may compromise the success of the sentinel lymph node biopsy, is very small. Nevertheless, these patients need to be successfully identified, appropriately advised and cautioned, and so do the surgeons that perform the procedure. Conclusion When performed by an experienced multi-disciplinary team, the SLNB is a highly effective and accurate alternative to standard level I and II axillary clearance in the vast majority of patients with early breast cancer.

Evaluation of a new T2 Magnetic Resonance assay for rapid detection of emergent fungal pathogen Candida auris on clinical skin swab samples.

Candida auris is a multidrug-resistant pathogenic yeast whose recent emergence is of increasing public-health concern. C. auris can colonize multiple body sites, including patients' skin, and survive for weeks in the healthcare environment, facilitating patient-to-patient transmission and fueling healthcare-associated outbreaks. Rapid and accurate detection of C. auris colonization is essential for timely implementation of infection control measures and prevent transmission. Currently, axilla/groin composite swabs, used to assess colonization status, are processed using a culture-based method that is sensitive and specific but requires 14 days. This delay limits the opportunity to respond and highlights the need for a faster alternative. The culture-independent T2 Magnetic Resonance (T2MR) system is a rapid diagnostic platform shown to detect target pathogens of interest from unprocessed blood samples in T2 assay was evaluated for screening of the skin surveillance samples. Inclusivity and limit of detection of the T2 C. auris assay were assessed with spiked samples in a representative skin flora background. The T2 C. auris assay recognized isolates from each of the 4 known clades of C. auris and consistently detected cells at 5 CFU/mL. Finally, 89 clinical axilla/groin swab samples were processed with the T2 C. auris assay. The culture-based diagnostic assay was used as a gold standard to determine performance statistics including sensitivity (0.89) and specificity (0.98). Overall, the T2 C. auris assay performed well as a rapid diagnostic and could help expedite the detection of C. auris in patient skin swabs. This article is protected by copyright.

Giant congenital melanocytic nevus (GCMN) is rare in babies of African descent. Unfortunately, it has an increased potential for malignant transformation. A 3-year-old female child presented with a 6-month history of multiple nodules on an existing giant congenital melanocytic nevus and swelling in the right axilla of four weeks duration. Skin biopsy of the nodular skin lesions was in keeping with a metastatic malignant melanoma (Clark stage 4). She completed a full course of chemotherapy but subsequently died four months after presentation. Patients with large GCMN should be counseled and followed up appropriately to improve and prolong life. © 2014 The International Society of Dermatology.

Full Text Available Fibroepithelial polyps are among common benign skin lesions. They are usually small and skin-colored lesions and are located frequently in the axilla and neck. They are rarely seen in the vulva. There is a small number of cases that reach the giant sizes in this area in the literature. A 20-year-old female patient presented with a pedunculated mass measuring 25 cm in diameter, localized to the right labium majus. The lesion was excised and the histopathological diagnosis was fibroepithelial polyp. We present this case because of it is the largest reported fibroepithelial polyp of the vulva in the literature.

The Clear-PEM scanner for positron emission mammography under development is described. The detector is based on pixelized LYSO crystals optically coupled to avalanche photodiodes and readout by a fast low-noise electronic system. A dedicated digital trigger (TGR) and data acquisition (DAQ) system is used for on-line selection of coincidence events with high efficiency, large bandwidth and small dead-time. A specialized gantry allows to perform exams of the breast and of the axilla. In this paper we present results of the measurement of detector modules that integrate the system under construction as well as the imaging performance estimated from Monte Carlo simulated data.

Five Roots Pattern of Median Nerve Formation

Konstantinos Natsis

2016-04-01

Full Text Available An unusual combination of median nerve’s variations has been encountered in a male cadaver during routine educational dissection. In particular, the median nerve was formed by five roots; three roots originated from the lateral cord of the brachial plexus joined individually the median nerve’s medial root. The latter (fourth root was united with the lateral (fifth root of the median nerve forming the median nerve distally in the upper arm and not the axilla as usually. In addition, the median nerve was situated medial to the brachial artery. We review comprehensively the relevant variants, their embryologic development and their potential clinical applications.

Ectopic breast tissue is defined as glands located outside of the breast. It can be found anywhere along the milk line extending from the axilla to the groin, and can occur in the vulva. Ectopic breast tissue should be excised because it may develop benign or malignant pathologic processes. Less than 40 cases of fibroadenoma in the vulva have been reported in the literature. We report a case of a 37-year-old woman presenting a solitary vulvar mass. The mass was excised completely, and histology demonstrated an ectopic breast fibroadenoma. This is one of the few reports on the benign pathologies of vulvar mammary glands.

The great majority of lymphangiomas occur in the neck (75%) and axilla (20%), but extremity lymphangioma is rare. We correlate variable sonographic features of extremity lymphangioma with pathologic findings. We reviewed the sonographic findings of extremity lymphangioma in 14 patients (M:F=8:6). The all cases were histologically confirmed by operation. The variable sonographic features of extremity lymphangioma were compared to pathologic findings. The multilocular cystic mass with ill defined boundaries was distinctive sonographic appearance of extremity lymphangioma. But there were variable sonographic findings such as heterogeneous echogenic mass or homogeneous echogenic portion. The histologic section of echogenic lesion reveals clusters of abnormal

A primary mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) of the breast is extremely rare. We report a case of a MALT lymphoma of the breast that presented as a palpable left breast mass in a 37-year-old woman. A physical examination revealed a large firm, and fixed mass in the left inner breast. Mammograms showed a large, isodense mass in the lower inner quadrant of the left breast and an enlarged lymph node in the axilla. A sonogram demonstrated a 5 cm sized, oval, circumscribed, and heterogeneously hypoechoic mass with posterior acoustic enhancement. A surgical biopsy was performed, and the pathology revealed a MALT lymphoma.

Sentinel lymph node biopsy has become a standard staging tool in the surgical management of breast cancer. The positive impact of sentinel lymph node biopsy on postoperative negative outcomes in breast cancer patients, without compromising the oncological outcomes, is its major advantage. It has evolved over the last few decades and has proven its utility beyond early breast cancer. Its applicability and efficacy in patients with clinically positive axilla who have had a complete clinical response after neoadjuvant chemotherapy is being aggressively evaluated at present. This article discusses how sentinel lymph node biopsy has evolved and is becoming a useful tool in new clinical scenarios of breast cancer management.

Full Text Available Abstract Background Epithelioid sarcomas of the hand are rare, high-grade tumors with a propensity for regional lymphatic spread approaching 40%. Case presentation A 54-year-old male with an epithelioid sarcoma of the palm was treated with neoadjuvant radiation, wide excision, and two-stage reconstruction. Sentinel lymph node biopsy was used to stage the patient's axilla. Sentinel node biopsy results were negative. The patient has remained free of local, regional and distant disease for the follow-up time of 16 months. Conclusion The rarity of this tumor makes definitive conclusions difficult but SLN biopsy appears to be a useful adjunct in the treatment of these sarcomas.

Recent studies have demonstrated low regional recurrence rates in early-stage breast cancer omitting axillary lymph node dissection (ALND) in patients who have positive nodes in sentinel lymph node dissection (SLND). This finding has triggered an active discussion about the effect of radiotherapy within this approach. The purpose of this study was to analyze the dose distribution in the axilla in standard tangential radiotherapy (SRT) for breast cancer and the effects on normal tissue exposure when anatomic level I-III axillary lymph node areas are included in the tangential radiotherapy field configuration. We prospectively analyzed the dosimetric treatment plans from 51 consecutive women with early-stage breast cancer undergoing radiotherapy. We compared and analyzed the SRT and the defined radiotherapy (DRT) methods for each patient. The clinical target volume (CTV) of SRT included the breast tissue without specific contouring of lymph node areas, whereas the CTV of DRT included the level I-III lymph node areas. We evaluated the dose given in SRT covering the axillary lymph node areas of level I-III as contoured in DRT. The mean V{sub D95} {sub %} of the entire level I-III lymph node area in SRT was 50.28 % (range, 37.31-63.24 %), V{sub D45} {sub Gy} was 70.1 % (54.8-85.4 %), and V{sub D40} {sub Gy} was 83.5 % (72.3-94.8 %). A significant difference was observed between lung dose and heart toxicity in SRT vs. DRT. The V{sub 20} {sub Gy} and V{sub 30} {sub Gy} of the right and the left lung in DRT were significantly higher in DRT than in SRT (p < 0.001). The mean heart dose in SRT was significantly lower (3.93 vs. 4.72 Gy, p = 0.005). We demonstrated a relevant dose exposure of the axilla in SRT that should substantially reduce local recurrences. Furthermore, we demonstrated a significant increase in lung and heart exposure when including the axillary lymph nodes regions in the tangential radiotherapy field set-up. (orig.)

Purpose: This prospective study was conducted to determine predictors of epidermal thickening during and after whole-breast radiation therapy (XRT) using objective measurements acquired with ultrasound. Methods and Materials: After breast-conserving surgery, 70 women received a definitive course of whole-breast XRT (50 Gy plus boost). Prior to XRT, at week 6 of XRT, and 6 weeks after XRT, patients underwent objective ultrasound measurements of epidermal thickness over the lumpectomy cavity and all 4 quadrants of the treated breast. A skin thickness ratio (STRA) was then generated normalizing for corresponding measurements taken of the untreated breast. Results: Baseline measurements indicated that 87% of patients had skin thickening in the treated versus untreated breast (mean increase, 27%; SD, 0.29) prior to XRT. The STRA increased significantly by week 6 of XRT (mean, 25%; SD, 0.46) and continued to increase significantly 6 weeks after XRT (mean, 33%; SD, 0.46) above baseline measurements (P<.001 for both time points). On multivariate analysis, breast volume (P=.003) and surgical evaluation of the axilla with full lymph node dissection (P<.05) predicted for more severe changes in the STRA 6 weeks after XRT compared with baseline. STRA measurements correlated with physician ratings of skin toxicity according to Radiation Therapy Oncology Group grading criteria. Conclusions: This is one of the first studies to objectively document that lymph node surgery affects XRT-induced skin thickening in patients with breast cancer. Surgical evaluation of the axilla with complete lymph node dissection was associated with the most severe XRT-induced skin changes after XRT completion. These results may inform future studies aimed at minimizing side effects of XRT and surgery, particularly when surgical lymph node assessments may not alter breast cancer management or outcome.

In the surgery of breast cancer, axillary reverse mapping (ARM) is the identification and preservation of arm draining lymph node (ARM node) during an axillary dissection. The assumption is that the ARM node is different from node draining breast and is unlikely to be involved even in the patients with axillary nodal metastases. If we can identify and preserve ARM node using lymphoscintigraphy; morbidity of lymphedema, as seen with axillary dissection, may be avoided. Pathologically proven 50 breast cancer patients undergoing initial surgery (cTx-4, cN0-2, and Mx-0) were included in this study. Less than 37 MBq, 0.5 ml in equally divided doses of filtered 99mTc sulfur colloid was injected intradermally into the second and third web spaces. ARM nodes in the axilla were identified with the help of Gamma Probe intraoperatively; however, their location was noted with the reference to specific anatomical landmarks and sent for histopathological examination after excision. The ARM node was successfully identified in 47/50 cases (sensitivity - 94%). In 40 out of 47 cases (85%), the location of the ARM node was found to lateral to the subscapular pedicle, above the second intercostobrachial nerve and just below the axillary vein. Of the 47 patients in whom ARM node/s were identified, metastasis was noted in 5 of them (10%). Four out of these 5 patients had the pN3 disease. ARM node exists, and it is feasible to identify ARM node using radio isotope technique with an excellent sensitivity. ARM node seems to have a fairly constant location in more than 80% cases. It is involved with metastasis (10% cases) only when there are multiple lymph nodal metastases in the axilla

Limited data are available examining the role of hypofractionated radiation schedules in the management of women requiring regional nodal irradiation (RNI). The purpose of this review is to examine the available literature for the efficacy (where available) and toxicity of hypofractionated radiation schedules in breast cancer with RNI limited to the axilla and supraclavicular regions. Multiple randomized and prospective studies have documented the safety and efficacy of hypofractionated schedules delivering whole breast irradiation (WBI) alone. Subsets from these randomized trials and smaller prospective/single-institution studies have documented the feasibility of hypofractionated RNI but the limited numbers prevent definitive conclusions and limited efficacy data are available. With regard to possible toxicity affecting organs at risk with RNI, key structures include the breast, skin, heart, lungs, axilla (lymphedema), and brachial plexus. Based on data from several randomized trials, hypofractionated radiation is not associated with significant changes in breast toxicity/cosmesis or cardiac toxicity; the addition of hypofractionated RNI would not be expected to change the rates of breast or cardiac toxicity. While RNI has been shown to increase rates of pulmonary toxicity, hypofractionated RNI has not been associated with more frequent pulmonary complications than standard RNI. Moving forward, future studies will have to evaluate for increased lung toxicity. With regard to lymphedema, data from randomized hypofractionated WBI trials failed to demonstrate an increase in lymphedema and smaller studies utilizing hypofractionated RNI have failed to as well. Data from head and neck cancer as well as hypofractionated breast radiation with RNI have failed to demonstrate an increase in brachial plexopathy with the exception of older trials that used much larger dose per fraction (>4 Gy/fraction) schedules. At this time, published data support the feasibility of

Despite the recent changes in the treatment of the axilla in selected breast cancer patient, positive sentinel lymph node (SLN) in patients undergoing mastectomy still necessitates axillary lymph node dissection (ALND). In invasive lobular carcinoma (ILC), pre-operative detection of the lymph node metastasis may be demanding due to its unique morphology. The aim of this study was to examine the benefit of preoperative axillary ultrasound (AUS), ultrasound-guided fine-needle aspiration biopsy (US-FNAB), and intra-operative imprint cytology (IIC), in order to avoid two-stage axillary surgery in patients with ILC undergoing mastectomy. The object of this study were 102 patients (median age 52, range 34-73 years) with clinically non-suspicious axilla in whom 108 mastectomies were performed after a pre-operative AUS investigation. Whenever a metastasis was detected in a sentinel lymph node, ALND was done. Reports of the pre-operative AUS investigation, US-FNAB, and IIC were compared with definitive histopathological reports of surgical specimens. In 46 cases lymph node metastases were diagnosed. AUS suspicious lymph nodes were found in 29/108 cases and histopathology confirmed metastases in 22/30 cases. US-FNAB was performed in 29 cases with AUS suspicious lymph nodes. Cytology proved metastases in 11/29 cases. Histopathology confirmed metastases in 10/11 cases with only isolated tumor cells found in one case. IIC investigation was performed in 63 cases and in 10/27 cases metastases were confirmed by histopathology. Pre-operative AUS, US-FNAB, and/or IIC investigation enabled ALND during a single surgical procedure in 20/46 patients with metastases in lymph nodes. Pre-operative AUS, US-FNAB, and/or IIC are/is beneficial in patients with ILC planned for mastectomy in order to decrease the number of two stage axillary procedures.

The individual, together with its environment, has been reported as the main force driving composition and structure of skin microbiota in healthy dogs. Therefore, one of the major concerns when analyzing canine skin microbiota is the likely influence of the environment. Despite the dense fur covering, certain skin diseases exhibit differential prevalence among skin sites, dog breeds, and individuals. We have characterized the normal variability of dog skin microbiota in a well-controlled cohort of a large number of Golden-Labrador Retriever crossed dogs (N = 35) with similar ages, related genetic background, and a shared environment. We found that the individual drives the skin microbiota composition and structure followed by the skin site. The main bacterial classes inhabiting dog skin in this cohort are Gammaproteobacteria and Bacilli. We also detected bacteria associated to the environment on different dog skin sites that could be reflecting the different degrees of exposure of each skin site and each dog. Network analyses elucidated bacterial interactions within and between skin sites, especially in the chin, abdomen, axilla, and perianal region, with the highly shared interactions probably representing an anatomical, behavioral, or environmental component. When analyzing each skin site independently to assess host-specific factors, we found that temporality (season of birth and time spent in the kennel) affected all the skin sites and specially the inner pinna. The most abundant taxon driving this difference was Sphingomonas. We also found taxonomic differences among male and female dogs on the abdomen, axilla, and back. We observed a large inter-individual variability and differences among skin sites. Host-specific variables, such as temporality or sex, were also shaping skin microbiota of healthy dogs, even in an environmental homogenous cohort.

Full Text Available Abstract Background Aim of the study was to determine the clinical efficacy of a new antiseptic liquid soap (Stellisept® scrub, based on the combination of undecylenamidopropyltrimonium methosulphate (4% and phenoxyethanol (2%, for eradication of MRSA among colonized patients who do not receive antibiotic therapy. Methods Over two years 50 MRSA patients in 6 hospitals were observed. Treatment was defined as the daily application of Stellisept scrub for the antiseptic body and hair wash (at least 60 s in combination with nasal mupirocin. A treatment cycle was a minimum of 5 days treatment. Screening was carried out at least 48 h after the treatment cycle was finished, with 24 h between each of the requested three or more samplings, which included the nasopharynx, groin, axilla, perineum and other MRSA-positive skin areas. Results Fifteen cases were retrospectively excluded (lack of outcome documentation, concomitant antibiotic therapy, open wounds. All 35 patients had colonization with MRSA before antiseptic treatment on the skin, in the groin (80%, the axilla (25.7%, the perineum (20% or other skin areas (14.3%. Colonization at more than one skin sites was found in 34.3%. Nasal colonization was found in 21 of 28 patients (75%, 7 patients were without nasal screening prior to the antiseptic treatment. After one treatment cycle MRSA was eradicated in 25 patients (71.4%, after a second cycle the total eradication rate was 91.4%, after a third cycle the rate increased to 94.2%. No patient discontinued the antiseptic treatment due to dermal intolerance of the product. Conclusions Progressive eradication of MRSA carriage was observed with the antiseptic soap and mupirocin. The eradication rate was not biased by concomitant antibiotic treatment, screening during treatment or lack of evidence for colonization in contrast to other studies with other preparations.

In patients with operable breast cancer, pre-operative evaluation of the axilla may be of use in the selection of appropriate axillary surgery. Pre-operative axillary ultrasound (US) and fine needle aspiration cytology (FNAC) assessments have become routine practice in many breast units, although the evidence base is still gathering. This study assessed the clinical utility of US+/-FNAC in patient selection for either axillary node clearance (ANC) or sentinel lymph node biopsy (SLNB) in patients undergoing surgery for operable breast cancer. Over a two-year period, 348 patients with a clinically negative axilla underwent axillary US. 67 patients with suspicious nodes on US also underwent FNAC. The sensitivity and specificity of axillary investigations to determine nodal involvement were 56% (confidence interval: 47-64%) and 90% (84-93%) for US alone, and 76% (61-87%) and 100% (65-100%) for FNAC combined with US, respectively. With a positive US, the post-test probability was 78%. A negative US carried a post-test probability of 25%. When FNAC was positive, the post-test probability was greater than unity. A negative FNAC yielded a post-test probability of 52%. All patients with positive FNAC and most patients with suspicious US were listed for axillary node clearance (ANC) after consideration at the multi-disciplinary team (MDT) meeting. With pre-operative axillary US+/-FNAC, 20% of patients were saved a potential second axillary procedure, facilitating a reduction in the overall re-operation rate to 12%. In this study, a positive pre-operative US+/-FNAC directs patients towards ANC. When the result is negative, other clinico-pathological factors need to be taken into account in the selection of the appropriate axillary procedure. Copyright © 2011 Elsevier Ltd.

To define the dosimetric coverage of level I/II axillary volumes and the lung volume irradiated in postmastectomy radiotherapy (PMRT) following tissue expander placement. Twenty-three patients were identified who had undergone postmastectomy radiotherapy with tangent only fields. All patients had pre-radiation tissue expander placement and expansion. Thirteen patients had bilateral expander reconstruction. The level I/II axillary volumes were contoured using the RTOG contouring atlas. The patient-specific variables of expander volume, superior-to-inferior location of expander, distance between expanders, expander angle and axillary volume were analyzed to determine their relationship to the axillary volume and lung volume dose. The mean coverage of the level I/II axillary volume by the 95% isodose line (V D95% ) was 23.9% (range 0.3 - 65.4%). The mean Ipsilateral Lung V D50% was 8.8% (2.2-20.9). Ipsilateral and contralateral expander volume correlated to Axillary V D95% in patients with bilateral reconstruction (p = 0.01 and 0.006, respectively) but not those with ipsilateral only reconstruction (p = 0.60). Ipsilateral Lung V D50% correlated with angle of the expander from midline (p = 0.05). In patients undergoing PMRT with tissue expanders, incidental doses delivered by tangents to the axilla, as defined by the RTOG contouring atlas, do not provide adequate coverage. The posterior-superior region of level I and II is the region most commonly underdosed. Axillary volume coverage increased with increasing expander volumes in patients with bilateral reconstruction. Lung dose increased with increasing expander angle from midline. This information should be considered both when placing expanders and when designing PMRT tangent only treatment plans by contouring and targeting the axilla volume when axillary treatment is indicated

Muscular variations during axillary dissection: A clinical study in fifty patients

Upasna

2015-01-01

Methods: The anatomy of axilla regarding muscular variations was studied in 50 patients who had an axillary dissection for the staging and treatment of invasive primary breast cancer over one year. Results: In a period of one year, two patients (4% with axillary arch and one patient (2% with absent pectoralis major and minor muscles among fifty patients undergoing axillary surgery for breast cancer were identified. Conclusions: Axillary arch when present should always be identified and formally divided to allow adequate exposure of axillary contents, in order to achieve a complete lymphatic dissection. Complete absence of pectoralis major and minor muscles precludes the insertion of breast implants and worsens the prognosis of breast cancer.

To present an unusual case of spontaneous pneumomediastinum subsequent to recreational amphetamine use. A young African American adult male was admitted to internal medicine service for treatment of rhabdomyolysis secondary to methamphetamine use. On admission, he was complaining of chest pain in addition to nausea and generalized muscle aches. By his second hospital day, chest pain had resolved yet physical exam demonstrated crepitation of the anterior chest and left axilla. Portable chest x-ray revealed subcutaneous emphysema in addition to pneumomediastinum. Spontaneous pneumomediastinum is a rare complication of amphetamine use that is often associated with subcutaneous emphysema and can be diagnosed with chest x-ray. Management is conservative, with observation, pain control, and supplemental oxygen as needed.

Full Text Available Radial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve. We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a 58-year-old male cadaver. The right sided structures were found to be normal. Neurosurgeons should keep such variations in mind while performing the surgeries of axilla and upper arm.

A full-term male infant presented at birth with a hard swelling of the left knee. The lemon-sized lesion was fixed to the underlying knee muscles, while the overlying skin was stretched and shiny; there was no bruit. Radiography, sonography and MRI suggested a soft-tissue tumour. After surgical excision, histology showed the presence of fibrous and mesenchymal tissue, with mature adipose tissue. Fibrous hamartoma of infancy was diagnosed. Among soft-tissue tumours, fibrous hamartoma of infancy is a rare and benign lesion, occurring in the first 2 years of life. The tumour mainly affects the trunk, axilla, and upper extremities. This infant had unique involvement of the knee. The treatment of choice is local excision. (orig.)

Unexpected visitor on FDG PET/CT--brown adipose tissue (BAT) in mesentery in a case of retroperitoneal extra-adrenal pheochromocytoma: is the BAT activation secondary to catecholamine-secreting pheochromocytoma?

Joshi, Prathamesh Vijay; Lele, Vikram Ramchandra

2012-05-01

Fused positron emission tomography-computed tomography (PET/CT) technology has enabled the determination that nonmalignant fluorodeoxyglucose (FDG) uptake is observed in brown adipose tissue (BAT). FDG uptake in BAT is a known potential source of false-positive interpretations for PET. The typical locations of BAT include neck, supraclavicular area, mediastinum, and paravertebral intercostal spaces. Examples of atypical locations for BAT include posterior neck, left paratracheal area, axillae, perirenal area, and retrocrural area. We report PET/CT findings in a young male patient with malignant retroperitoneal extra-adrenal pheochromocytoma, who demonstrated FDG uptake in BAT at multiple locations including mesenteric BAT. We also propose catecholamine-secreting pheochromocytoma as a possible cause of BAT activation in our case.

Scrotal elephantiasis has been a recognized complication of inguinal node irradiation, filarial infection, tumor involvement and surgical lymphatic destruction, but has rarely been reported in association with hidradenitis suppurativa (HS). HS, also known as acne inversa, is a chronic and often debilitating disease primarily affecting the axillae, inframammary regions and perineum. The location of the lesions may lead to social embarrassment and failure to seek medical treatment. Scroto-preineal HS complicated by scrotal elephantiasis is a distressing disease. Excisional surgery with reconstruction is the recommended treatment with a high likelihood of good outcome. We present a 38-year-old male patient with long-standing scroto-perineal HS complicated by giant scrotal elephantiasis.

Full Text Available In the present study, we investigated the prevalence and intensity of Hectopsylla pulex infection in Molossus rufus and Molossus molossus, the parasite's choice of attachment site, and whether this host-parasite system varies with host size. Twenty-four bats were captured by hand from the roof of a house in Southeastern Brazil. M. rufus exhibited a prevalence of 71.4% and the mean intensity averaged 5 ectoparasites per bat. M. molossus exhibited a prevalence of 90%, and the average mean intensity was 2.11 ectoparasites. The attachment sites were: ear, tragus, shoulder blade and tibia, anus, wing, axilla, mouth and dactylopatagium. A positive correlation was observed between the bats' weight and the number of fleas.

A full-term male infant presented at birth with a hard swelling of the left knee. The lemon-sized lesion was fixed to the underlying knee muscles, while the overlying skin was stretched and shiny; there was no bruit. Radiography, sonography and MRI suggested a soft-tissue tumour. After surgical excision, histology showed the presence of fibrous and mesenchymal tissue, with mature adipose tissue. Fibrous hamartoma of infancy was diagnosed. Among soft-tissue tumours, fibrous hamartoma of infancy is a rare and benign lesion, occurring in the first 2 years of life. The tumour mainly affects the trunk, axilla, and upper extremities. This infant had unique involvement of the knee. The treatment of choice is local excision. (orig.)

2005-01-01

Full Text Available During dissection of a 55-year-old female cadaver, we observed that three nerve roots contributed to the formation of Median nerve in her right upper limb. Along with this variation, absence of Musculocutaneous nerve was noticed. The muscles of front of arm i.e. Biceps Brachii, Brachialis and Coracobrachialis received their nerve supply from Median nerve. The Lateral cutaneous nerve of forearm was derived from Median nerve. Also an accessory head of Biceps Brachii muscle was present in the right arm of the same cadaver. It is extremely important to be aware of these variations while planning a surgery in the region of axilla or arm as these nerves are more liable to be injured during operations.

Full Text Available Methicillin resistant Stephylococcus aureus (MRSA infection has now become a major problem in hospitals. We present a case of postoperative infection MRSA where the primary source of the infection was found to be an abdominal mesh that was used to reinforce the abdominal wall. After one year of surgery, the patient developed wound dehiscence and discharge. MRSA was isolated from the wound, mesh, external nares, throat and axilla. Initially she was started on clindamycin and discharged from the hospital. After 5 months, patient came back to the hospital with infection at the same site. The patient was then treated with vancomycin and MRSA clearance. She responded to the treatment with complete healing of the wound and clearance of MRSA.

Full Text Available Dowling–Degos disease (DDD and reticulate acropigmentation of Kitamura (RAK are rare genodermatoses inherited as an autosomal dominant trait with variable penetrance. They are considered to be part of a spectrum of reticulate pigmentary dermatoses, characterized by the presence of hyperpigmented macules coalescing in a reticular fashion. The authors describe a 28-year-old male patient having hyperpigmented macules on the axillae, neck and face, reticulate acropigmentation of dorsum of the hands, forearms and feet, palmar pitting, and comedo-like lesions over back. The patient showed the unique clinical as well as histopathological overlap of both the rare diseases (DDD and RAK, substantiating the hypothesis that they represent two different features of a single entity with variable phenotypic expression.

Facial Localization of Malignant Chondroid Syringoma: A Rare Case Report

Full Text Available First described by Hirsch and Helwig in 1961, chondroid syringomas (CSs are rare, benign tumors of the skin arising from the eccrine sweat glands with tumor differentiation in the epithelial and mesenchymal tissues. They most commonly occur in the head and neck, although they may be also found in the axilla, trunk, limbs, and genitalia. The incidence of CS is <0.01% of all primary skin tumors. Malingnant chondroid syringomas (MCS, which are also called malignant mixed tumors of the skin, are extremely uncommon. MCSs commonly involve the limbs and rarely head and neck. In this article, we present a case of malignant chondroid syringoma localized in the face at the left nasolabial region in the light of literature review.

Endoscopic foraminal decompression for failed back surgery syndrome under local anesthesia.

Science.gov (United States)

Yeung, Anthony; Gore, Satishchandra

2014-01-01

The most common causes of failed back surgery are residual or recurrent herniation, foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. Residual back ache may also be from facetal causes or denervation and scarring of the paraspinal muscles.(1-6) The original surgeon may advise his patient that nothing more can be done on the basis of his opinion that the nerve was visually decompressed by the original surgery, supported by improved post-op imaging and follow-up studies such as EMG and conduction velocity studies. Post-op imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of Failed back surgery by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain, therefore necessitating fusion. The authors, having limited their practice to endoscopic MIS surgery over the last 15-20 years, report on their experience gained during that period to relieve pain by endoscopically visualizing and treating unrecognized causative patho-anatomy in FBSS.(7.) Thirty consecutive patients with FBSS presenting with back and leg pain that had supporting imaging diagnosis of lateral stenosis and /or residual / recurrent disc herniation, or whose pain complaint was supported by relief from diagnostic and therapeutic injections (Figure 1), were offered percutaneous transforaminal endoscopic discectomy and foraminoplasty over a repeat open procedure. Each patient sought consultation following a transient successful, partially successful or unsuccessful open translaminar surgical treatment for disc herniation or spinal stenosis. Endoscopic foraminoplasty was also performed to either decompress the bony foramen for foraminal stenosis, or foraminoplasty to allow for endoscopic visual examination of the affected traversing and exiting nerve roots in the axilla, also known as the "hidden zone" of Macnab

The success of ectoparasites depends primarily on the site of attachment and body condition of their hosts. Ticks usually tend to aggregate on vertebrate hosts in specific areas, but the distribution pattern may depend on host body size and condition, sex, life stage or skin morphology. Here, we studied the distribution of ticks on lizards and tested the following hypothesis: occurrence or high abundance of ticks is confined with body parts with smaller scales and larger interscalar length because such sites should provide ticks with superior attachment conditions. This study was performed in field conditions in central Poland in 2008-2011. In total, 500 lizards (Lacerta agilis) were caught and 839 ticks (Ixodes ricinus, larvae and nymphs) were collected from them. Using generalised linear mixed models, we found that the ticks were most abundant on forelimbs and their axillae, with 90% of ticks attached there. This part of the lizard body and the region behind the hindlimb were covered by the smallest scales with relatively wide gaps between them. This does not fully support our hypothesis that ticks prefer locations with easy access to skin between scales, because it does not explain why so few ticks were in the hindlimb area. We found that the abundance of ticks was positively correlated with lizard body size index (snout-vent length). Tick abundance was also higher in male and mature lizards than in female and young individuals. Autotomy had no effect on tick abundance. We found no correlation between tick size and lizard morphology, sex, autotomy and body size index. The probability of occurrence of dead ticks was positively linked with the total number of ticks on the lizard but there was no relationship between dead tick presence and lizard size, sex or age. Thus lizard body size and sex are the major factors affecting the abundance of ticks, and these parasites are distributed nearly exclusively on the host's forelimbs and their axillae.

The aim of this study was to compare, in breast cancer patients, the diagnostic accuracy of positron emission tomography (PET) using fluorine-18 fluorodeoxyglucose (FDG) and scintimammography (SMM) using technetium-99m methoxyisobutylisonitrile (MIBI). A total of 20 patients (40 breasts with 22 lesions) were evaluated serially with MIBI and, on the following day, with FDG. For SMM, planar and single-photon emission tomography imaging in the prone position was performed starting at 10 min following the injection of MIBI (740 MBq). For PET, scans were acquired 45-60 min after the injection of FDG (370 MBq) and attentuation correction was performed following transmission scans. Results from SMM and PET were subsequently compared with the histopathology results. True-positive results were obtained in 12/13 primary breast cancers (mean diameter=29 mm, range 8-53 mm) with both FDG and MIBI. False-negative results were obtained in two local recurrences (diameter <9 mm) with both FDG and MIBI. In benign disease, FDG and MIBI did not localize three fibrocystic lesions, two fibroadenomas and one inflammatory lesion (true-negative), but both localized one fibroadenoma (false-positive). Collectively, the results demonstrate a sensitivity of 92%, and a specificity of 86%, for primary breast cancer regardless of whether FDG or MIBI was used. In contrast to MIBI scintigraphy, FDG PET scored the axillae correctly as either positive (metastatic disease) or negative (no axillary disease) in all 12 patients. The tumour/non-tumour ratio for MIBI was 1.97 (range 1.43-3.1). The mean standard uptake value (SUV) for FDG uptake was 2.57 (range 0.3-6.2). The diagnostic accuracy of SMM was equivalent to that of FDG PET for the detection of primary breast cancer. For the detection of in situ lymph node metastases of the axilla, FDG seems to be more sensitive than {sup 99m}Tc-MIBI. (orig.). With 4 figs., 2 tabs.

Trials failed to demonstrate additional value of completion axillary lymph node dissection in case of limited sentinel lymph node metastases in breast cancer patients undergoing breast conserving therapy. It has been suggested that the low regional recurrence rates in these trials might partially be ascribed to accidental irradiation of part of the axilla by whole breast radiation therapy, which precludes extrapolation of results to mastectomy patients. The aim of the randomized controlled BOOG 2013–07 trial is therefore to investigate whether completion axillary treatment can be safely omitted in sentinel lymph node positive breast cancer patients treated with mastectomy. This study is designed as a non-inferiority randomized controlled multicentre trial. Women aged 18 years or older diagnosed with unilateral invasive clinically T1-2 N0 breast cancer who are treated with mastectomy, and who have a maximum of three axillary sentinel lymph nodes containing micro- and/or macrometastases, will be randomized for completion axillary treatment versus no completion axillary treatment. Completion axillary treatment can consist of completion axillary lymph node dissection or axillary radiation therapy. Primary endpoint is regional recurrence rate at 5 years. Based on a 5-year regional recurrence free survival rate of 98 % among controls and 96 % for study subjects, the sample size amounts 439 per arm (including 10 % lost to follow-up), to be able to reject the null hypothesis that the rate for study and control subjects is inferior by at least 5 % with a probability of 0.8. Results will be reported after 5 and 10 years of follow-up. We hypothesize that completion axillary treatment can be safely omitted in sentinel node positive breast cancer patients undergoing mastectomy. If confirmed, this study will significantly decrease the number of breast cancer patients receiving extensive treatment of the axilla, thereby diminishing the risk of morbidity and improving quality of

Purpose: Positron emission tomography/computed tomography (PET/CT) is increasingly being utilized for staging of inflammatory breast cancer (IBC). The purpose of this study was to define how pretreatment PET/CT studies affected postmastectomy radiation treatment (PMRT) planning decisions for IBC. Methods and Materials: We performed a retrospective analysis of 62 patients diagnosed with IBC between 2004 and 2009, who were treated with PMRT in our institution and who had a staging PET/CT within 3 months of diagnosis. Patients received a baseline physical examination, staging mammography, ultrasonographic examination of breast and draining lymphatics, and chest radiography; most patients also had a bone scan (55 patients), liver imaging (52 patients), breast MRI (46 patients), and chest CT (25 patients). We compared how PET/CT findings affected PMRT, assuming that standard PMRT would target the chest wall, level III axilla, supraclavicular fossa, and internal mammary chain (IMC). Any modification of target volumes, field borders, or dose prescriptions was considered a change. Results: PET/CT detected new areas of disease in 27 of the 62 patients (44%). The areas of additional disease included the breast (1 patient), ipsilateral axilla (1 patient), ipsilateral supraclavicular (4 patients), ipsilateral infraclavicular (1 patient), ipsilateral IMC (5 patients), ipsilateral subpectoral (3 patients), mediastinal (8 patients), other distant/contralateral lymph nodes (15 patients), or bone (6 patients). One patient was found to have a non-breast second primary tumor. The findings of the PET/CT led to changes in PMRT in 11 of 62 patients (17.7%). These changes included additional fields in 5 patients, adjustment of fields in 2 patients, and higher doses to the supraclavicular fossa (2 patients) and IMC (5 patients). Conclusions: For patients with newly diagnosed IBC, pretreatment PET/CT provides important information concerning involvement of locoregional lymph nodes

Currently, there is no widely accepted treatment for the disorder, but it is usually treated with bleaching agents because it is considered a variant of inflammatory hyperpigmentation. The purpose of this study was to assess the efficacy of niacinamide 4% and desonide 0.05% emulsions compared with placebo in the treatment of axillary hyperpigmentation.Methods: Twenty-four women aged 19–27 years with hyperpigmented axillae (phototype III–V were randomly assigned to receive the study treatments in the axillary region. Improvement was assessed at baseline, then clinically and by colorimetry 9 weeks later. Quantitative evaluation including melanin, inflammatory infiltrates, NKI/Beteb, CD1a, CD68, and collagen type IV content was performed by histochemistry and immunohistochemistry, assisted by computerized morphometric analysis.Results: Both niacinamide and desonide induced significant colorimetric improvement compared with placebo; however, desonide showed a better depigmenting effect than niacinamide. A good to excellent response was achieved in 24% of cases for niacinamide, 30% for desonide, and 6% for placebo. We observed a marked disruption of the basal membrane in axillary hyperpigmentation and an inflammatory infiltrate that improved after treatment. Decreased pigmentation in the desonide-treated axillae was associated with recovery of disruption at the basal membrane

In the human body, the lymph nodes groups like in the groin, axilla, neck and others regions, receive the lymphatic drainage from a determined corporal territory, and the first node to receive it is called the sentinel node and as the name suggest, it is the most likely node to contain metastases if present; in the axilla the sentinel node is usually localized in level I. The presence of regional lymph node involvement remains the most reliable prognostic factor and provides accurate nodal staging for woman with epithelial cancers. The most commonly use indicator of prognosis for patients with operable carcinoma of the breast is the histological presence or absence of axillary lymph node metastases. The sentinel node biopsy is a new procedure composed of two steps: the first is the lymphatic mapping where the sentinel node can be identified in the preoperative period by lymphoscintigraphy, and in the operating room by injection of a vital blue dye, and with technetium labeled sulfur colloid injected into the same area as the vital blue dye or in place of the blue dye. In the second step the extracted and a rigorous assessment of the accuracy by pathological examination. Multiple studies have showed that if the sentinel lymph node is negative for metastatic disease, the remaining lymph nodes are also likely to be negative. The value of the sentinel lymph node biopsy is based in the pathologic diagnosis, when it is negative it is possible to avoid axillary dissection. The technique of identification of sentinel lymph node is applied to different types of cancers and distinct localizations, in the penis, malignant melanoma, breast, head and neck (oral cavity, epidermoid carcinoma, malignant melanoma), vulva, gastric, colorectal, 'non small cell lung cancer' and for merkel cell carcinoma. This publication regarding the sentinel lymph node technique and its applications in cancer, represents the routine followed in the Department of Breast Bone and Mixed Tumours of the

Eddiba Tarik

2013-01-01

Full Text Available Congenital infantile fibrosarcoma (CIFS is a rare mesenchymal tumor that is primarily developed in the soft tissue of distal extremities and occasionally in unusual locations such as the lung and retroperitoneum. It occurs mainly in children below the age of 5 years. About 200 cases have been reported in the literature so far, very few of them in new-borns. The prognosis of this tumor is relatively good compared to adult forms. We report an unusual case of CIFS occurring in new-born mimicking an hemangioma and causing hemorrhage in the neonatal period. The tumor is located in the left arm and axilla and associated with a hand malformation. A shoulder amputation is performed after chemotherapy failure. The infant is now two-years old with no recurrence.

We compared simulator images of medial tangential fields taken in two positions: (1) with the ipsilateral arm abducted, holding a 'L-bar' armrest and (2) with both arms extended above the head in a forearm support. The average maximum heart distance as well as the central lung distance decreased significantly by 3.4 (SE 0.9) and 4.7 (SE 1.1) mm, respectively, when the new forearm support was used. The estimated normal tissue complication probability for excess cardiac mortality decreased by on average 3.1% (SE 1.3%). For some patients, a greater amount of the axilla was included in the field. We recommend the use of the forearm support during breast cancer treatment with tangential fields to decrease the amount of heart and lung inside the fields

Quality control in breast conservation

International Nuclear Information System (INIS)

Schwartz, G.F.

1992-01-01

Over the past 15 years, breast conservation has become an accepted option for treatment of Stages I and II carcinoma of the breast; in this practice in 1991, more than 80% of these patients were treated in this manner. A surgical procedure to excise the primary lesion and to dissect the axilla is generally required to prepare patients for breast conservation, concurrently maximizing esthetic appearance of the breast, minimizing the risk of local recurrence and providing appropriate information for recommendations concerning adjuvant therapy. The volume of breast tissue to be removed, significance of findings at surgical margins, and extent of the axillary dissection are all somewhat controversial subjects. Based upon a personal series of almost 800 patients undergoing breast conservation, observations that reflect the findings from this experience may be shared. (author)

Lymphangioma are rare benign lesions and it is difficult to state whether they are true neoplasm, hamartomas or lymphangiectasias. They are most commonly seen in children and occur in regions of the neck and axilla. They increase in size both by proliferation and by the collection of fluid, thus forming cysts. The authors report a case of a 70-year-old man, who presented abdominal swelling, a palpable mass in both flanks and polycythemia. Abdominal sonography, kidney arteriograpy, CT scan and MRI have shown multiple cysts bilaterally surrounding the kidneys without either parenchymal or functional involvement. During surgery several intercommunicating cysts were found surrounding both kidneys. Biopsies were taken from the perirenal fat, the wall of the cysts and the kidney. The histologic diagnosis was cystic lymphangioma. (author) 11 refs., 4 figs.

Full Text Available Ecthyma gangrenosum (EG is a cutaneous lesion classically associated with potentially fatal Pseudomonas septicemia in immunocompromised patients. Other bacterial and fungal pathogens have also been implicated. Although EG typically occurs in immunocompromised or neutropenic patients, it may occasionally affect a previously healthy person. The cutaneous findings are characteristic with small indurated papulovesicles progressing rapidly to necrotic ulcers with surrounding erythema and a central black Eschar. While lesions can occur at any site, most are commonly found over the buttocks, perineum, limbs, and axillae. We describe a case of EG in periorbital region in a previously healthy woman who responded to appropriate antibiotic treatment for Pseudomonas. It is very important to establish the diagnosis early so that appropriate systemic antibiotic therapy can be initiated to reduce morbidity and potential mortality.

Arm morbidity following sentinel lymph node biopsy or axillary lymph node dissection: a study from the Danish Breast Cancer Cooperative Group

DEFF Research Database (Denmark)

Husted, Madsen A.; Haugaard, K.; Soerensen, J.

2008-01-01

BACKGROUND: Sentinel lymph node biopsy was implemented in the treatment of early breast cancer with the aim of reducing shoulder and arm morbidity. Relatively few prospective studies have been published where the morbidity was assessed by clinical examination. Very few studies have examined...... lymph node biopsy with node negative patients having a lymph node dissection of levels I and II of the axilla, we found significant increase in arm volume among the patients who had an axillary dissection. Only minor, but significant, differences in shoulder mobility were observed comparing the two...... groups of node negative patients. Highly significant difference was found comparing sensibility. Comparing the morbidity in node positive patients who had a one-step axillary dissection with patients having a two-step procedure (sentinel lymph node biopsy followed by delayed axillary dissection) revealed...

Full Text Available Nevus comedonicus is a rare epidermal abnormality of the pilosebaceous unit, which is congenital in most patients but may also appear early in childhood. It may be localized or have an extensive involvement, the latter showing a unilateral predominance with only a few cases presenting bilaterally. Extensive nevus comedonicus can be associated with musculoskeletal defects, eye and neurological involvement, which constitutes nevus comedonicus syndrome. Uncomplicated nevus comedonicus can be treated with topical keratolytics, diode, erbium laser, and ultrapulse CO2 laser. Surgical excision can be performed to ensure complete removal and nonrecurrence. This case report refers to a young male patient with extensive nevus comedonicus present over left chest, left axilla, and left upper back without systemic involvement, treated with staged surgical excision and resurfacing.

Délio Marques Conde

Full Text Available CONTEXT: Supernumerary breast tissue may be affected by the same diseases and alterations that compromise topical breast tissue. Nevertheless, reports of fibroadenoma in supernumerary breast tissue in the axillae are rare. OBJECTIVE: To describe a case of fibroadenoma in an axillary supernumerary breast. DESIGN: Case report. CASE REPORT: A 39-year-old woman was referred to the gynecology and obstetrics outpatient clinic at Hospital Estadual Sumaré, complaining of bilateral axillary masses. The patient reported cosmetic problems and local pain and discomfort. On physical examination, alterations compatible with bilateral axillary accessory breasts, without palpable nodules, were observed. Supplementary examinations (mammography and ultrasonography revealed a 1.1 cm mass in the right axillary breast. The patient underwent resection of the supernumerary breasts and histopathological examination revealed fibroadenoma of the right axillary breast tissue.

This study was undertaken to determine whether 131-I labeled B72.3 monoclonal antibody, when injected subcutaneously in patients with known breast cancer, successfully detects lymph node metastases. Eleven women with biopsy-proven B72.3 antibody-reactive breast cancer (determined by immunoperoxidase staining) received subcutaneous injections of 500 μ Ci 131-I B72.3 in ipsilateral finger web spaces (or, in three cases, intralesional injections into the site of the breast tumor). The antibody is a IgGlk reactive with a high molecular weight antigen found on most breast carcinomas. Images of the axilla were obtained immediately after injection and serially to 72 hours. Nodal uptake was scored on a 0-3+ scale in a blinded fashion and correlated with pathologic findings from lymph node dissection

Variation of the latissimus dorsi

Full Text Available A typical muscle variation of latissimus dorsi - the axillary arch is represented by the muscular or fibromuscular slip detached from the anteroinferior border of the musculus latissimus dorsi passing over the axilla under the axillary fascia crossing the medial side of the brachial plexus to continue as a septum intermusculare mediale brachii distally to the medial epicondyle of humerus. The full extent of the muscle is rarely present. Slips of muscle extend from the latissimus dorsi at the inferior angle of scapula to insert into pectoralis major (Langer, coracobrachilis, biceps or coracoid process forming what is described as a common variant - the muscular axillary arch. We report three cases of variants of latissimus dorsi, one of which has not been reported in the literature before.

1998-01-01

A case of radiation-induced sarcoma of the chest wall after radiation therapy for breast cancer is reported. A 69-year-old woman underwent mastectomy with axillary lymph node dissection followed by linac therapy of 50 Gy delivered to the left axilla, left supraclavicular area, and parasternal area. During therapy for bone and liver metastases, a tumor was noted in the left chest wall 15 years after radiation therapy. Incisional biopsy was performed. Histological diagnosis was spindle cell sarcoma. Radiation-induced sarcoma was suspected because the tumor developed 15 years after radiation therapy within the same area. Radiation-induced sarcoma is a rare tumor, but radiation therapy following breast-conserving therapy is widely employed. It is important to be aware of the possibility of radiation-induced sarcoma.

2017-01-01

Frontal fibrosing alopecia is a variant of lichen planopilaris with marginal progressive hair loss on the scalp, eyebrows and axillae. We report a case of frontal fibrosing alopecia and lichen planus pigmentosus in a postmenopausal woman, that started with alopecia on the eyebrows and then on the frontoparietal region, with periocular and cervical hyperpigmentation of difficult management. The condition was controlled with systemic corticosteroid therapy and finasteride. Lichen planus pigmentosus is an uncommon variant of lichen planus frequently associated with frontal fibrosing alopecia in darker phototipes. It should be considered in patients affected by scarring alopecia with a pattern of lichen planopilaris and areas of skin hyperpigmentation revealing perifollicular hyperpigmentation refractory to multiple treatments. This case illustrates diagnostic and therapeutic challenge in face of scarring alopecia and perifollicular hyperpigmentation.

A negative sentinel lymph node (SLN) biopsy spares many breast cancer patients the complications associated with lymph node irradiation or additional surgery. However, patients at high risk for nodal involvement based on clinical characteristics may remain at unacceptably high risk of axillary disease even after a negative SLN biopsy result. A Bayesian nomogram was designed to combine the probability of axillary disease prior to nodal biopsy with customized test characteristics for an SLN biopsy and provides the probability of axillary disease despite a negative SLN biopsy. Users may individualize the sensitivity of an SLN biopsy based on factors known to modify the sensitivity of the procedure. This tool may be useful in identifying patients who should have expanded up front exploration of the axilla or comprehensive axillary irradiation

Sentinel lymph node mapping in breast cancer: a critical reappraisal of the internal mammary chain issue.

Although, like the axilla, the internal mammary nodes (IMNs) are a first-echelon nodal drainage site in breast cancer, the importance of their treatment has long been debated. Seminal randomized trials have failed to demonstrate a survival benefit from surgical IMN dissection, and several retrospective studies have shown that IMNs are rarely the first site of recurrence. However, the recent widespread adoption of sentinel lymph node (SLN) biopsy has stimulated a critical reappraisal of such early results. Furthermore, the higher proportion of screening-detected cancers, improved imaging and techniques (i.e., lymphoscintigraphy for radioguided SLN biopsy) make it possible to visualize lymphatic drainage to the IMNs. The virtually systematic application of adjuvant systemic and/or loco-regional radiotherapy encourages re-examination of the significance of IMN metastases. Moreover, randomized trials testing the value of postmastectomy irradiation and a meta-analysis of 78 randomized trials have provided high levels of evidence that local-regional tumor control is associated with long-term survival improvements. This benefit was limited to trials that used systemic chemotherapy, which was not routinely administered in the earlier studies. However, the contribution from IMN treatment is unclear. Lymphoscintigraphic studies have shown that a significant proportion of breast cancers have primary drainage to the IMNs, including approximately 30% of medial tumors and 15% of lateral tumors. In the few studies where IMN biopsy was performed, 20% of sentinel IMNs were metastatic. The risk of IMN involvement is higher in patients with medial tumors and positive axillary nodes. IMN metastasis has prognostic significance, as recognized by its inclusion in the American Joint Committee on Cancer staging criteria, and seems to have similar prognostic importance as axillary nodal involvement. Although routine IMN evaluation might be indicated, it has not been routinely performed

An unusual case of isolated, serial metastases of gallbladder carcinoma involving the chest wall, axilla, breast and lung parenchyma

Matthew J. Iott

2013-02-01

Full Text Available In the English literature, only 9 cases of adenocarcinoma of the gallbladder with cutaneous metastasis have been reported so far. One case of multiple cutaneous metastases along with deposits in the breast tissue has been reported. We present a case of incidental metastatic gallbladder carcinoma with no intra-abdominal disease presenting as a series of four isolated cutaneous right chest wall, axillary nodal, breast and pulmonary metastases following resection and adjuvant chemoradiation for her primary tumor. In spite of the metastatic disease coupled with the aggressive nature of the cancer, this patient reported that her energy level had returned to baseline with a good appetite and a stable weight indicating a good performance status and now is alive at 25 months since diagnosis. Her serially-presented, oligometastatic diseases were well-controlled by concurrent chemoradiation and stereotactic radiation therapy. We report this case study because of its rarity and for the purpose of complementing current literature with an additional example of cutaneous metastasis from adenocarcinoma of the gallbladder.

Hidradenitis suppurativa (HS) is a chronic and debilitating suppurative disease primarily affecting the axillae, perineum, and inframammary regions, where apocrine sweat glands are present. However, HS can occur in atypical locations. We present an interesting case of a 40-year-old man who developed chronic painful subcutaneous nodules, deep sinus tracts, and abscesses involving the jawline and the anterior aspect of the neck as the only parts of the body affected and who responded satisfactorily to adalimumab and laser hair removal treatment. This case is relevant because it helps clinicians to remember that HS may be isolated to atypical locations, such as the anterior aspect of the neck and chin. It also supports another possible HS pathogenesis which consists of the occlusion of terminal hair follicles rather than being essentially a disorder of the apocrine glands.

Sclerotic fibroma (storiform collagenoma)-like stroma in a fibroadenoma of axillary accessory breast tissue.

2012-08-01

Accessory breast tissue is a subcutaneous remnant persisting after normal embryological development of the breast. It occurs most frequently in the axilla. Fibroadenomas in axillary breast tissue are rare. We report the case of a 29-year-old female patient who presented a fibroadenoma arising in the accessory breast tissue of the right axillary fossa. The neoplasm showed foci of sclerotic fibroma-like stroma. The patient had no signs of Cowden's syndrome. To the best of our knowledge, a lesion of this kind has not been previously reported. This stromal change suggests an uncommon involutional phase of the fibroadenoma with production of sclerotic and hypocellular collagen. The lesion should be differentiated from extraneural perineuroma, from the changes in fibroadenomas in Cowden's syndrome, from sclerosing lobular hyperplasia (fibroadenomatoid mastopathy) and from pseudoangiomatous stromal hyperplasia.

Histologic paraffin sections of pseudoxanthoma elasticum (PXE)-involved skin of forearm and axilla were used for histochemistry and immunohistochemical and analytical electron microscopy to study the progressive mineralization in the dermis of patients with PXE. The von Kossa technique identified mineral deposits throughout the reticular PXE dermis. X-ray analysis revealed patterns of calcium and phosphorus deposition in the von Kossa-positive areas, and the immunohistochemical staining using monoclonal antibodies identified increased chondroitin-6-sulfate in these areas when compared with normal skin. Scanning transmission electron microscopy observation combined with X-ray dot mapping show calcium and phosphorus to be codistributed within the mineralized area. This study confirms by new methods the increase in chondroitin-6-sulfate, alterations in elastin and collagen, and a high calcium and phosphorus elemental distribution matching the mineralized area in the PXE dermis

Full Text Available Background: Oral opioid analgesics have been used for management of peri- and postoperative analgesia in patients undergoing axillary dissection. The axillary region is a difficult zone to block and does not have a specific regional anesthesia technique published that offers its adequate blockade. Methods: After institutional review board approval, anatomic and radiological studies were conducted to determine the deposition and spread of methylene blue and local anesthetic injected respectively into the axilla via the thoracic inter-fascial plane. Magnetic Resonance Imaging studies were then conducted in 15 of 34 patients scheduled for unilateral breast surgery that entailed any of the following: axillary clearance, sentinel node biopsy, axillary node biopsy, or supernumerary breasts, to ascertain the deposition and time course of spread of solution within the thoracic interfascial plane in vivo. Results: Radiological and cadaveric studies showed that the injection of local anesthetic and methylene blue via the thoracic inter-fascial plane, using ultrasound guide technique, results in reliable deposition into the axilla. In patients, the injection of the local anesthetic produced a reliable axillary sensory block. This finding was supported by Magnetic Resonance Imaging studies that showed hyper-intense signals in the axillary region. Conclusions: These findings define the anatomic characteristics of the thoracic interfascial plane nerve block in the axillary region, and underline the clinical potential of this novel nerve block. Resumo: Justificativa: Os analgésicos orais à base de opioides têm sido usados para o manejo da analgesia nos períodos peri e pós-operatório de pacientes submetidos à linfadenectomia axilar. A região axilar é uma zona difícil de bloquear e não há registro de uma técnica de anestesia regional específica que ofereça o seu bloqueio adequado.

Purpose To prospectively demonstrate the feasibility of using indocyanine green, a near-infrared (NIR) fluorophore at the minimum dose needed for noninvasive optical imaging of lymph nodes (LNs) in breast cancer patients undergoing sentinel lymph node mapping (SLNM). Materials and Methods Informed consent was obtained from 24 women (age range, 30–85 years) who received intradermal subcutaneous injections of 0.31–100 μg indocyanine green in the breast in this IRB-approved, HIPAA-compliant, dose escalation study to find the minimum microdose for imaging. The breast, axilla, and sternum were illuminated with NIR light and the fluorescence generated in the tissue was collected with an NIR-sensitive intensified charged-coupled device. Lymphoscintigraphy was also performed. Resected LNs were evaluated for the presence of radioactivity, blue dye accumulation, and fluorescence. The associations between the resected LNs that were fluorescent and (a) the time elapsed between NIR fluorophore administration and resection and (b) the dosage of NIR fluorophores were tested with the Spearman rank and Pearson product moment correlation tests, respectively. Results Lymph imaging consistently failed with indocyanine green microdosages between 0.31 and 0.77 μg. When indocyanine green dosages were 10 μg or higher, lymph drainage pathways from the injection site to LNs were imaged in eight of nine women; lymph propulsion was observed in seven of those eight. When propulsion in the breast and axilla regions was present, the mean apparent velocities ranged from 0.08 to 0.32 cm/sec, the time elapsed between “packets” of propelled fluid varied from 14 to 92 seconds. In patients who received 10 μg of indocyanine green or more, a weak negative correlation between the fluorescence status of resected LNs and the time between NIR fluorophore administration and LN resection was found. No statistical association was found between the fluorescence status of resected LNs and the dose of

Purpose: To compare dosimetric endpoints between proton therapy (PT) and conventional radiation and determine the feasibility of PT for regional nodal irradiation (RNI) in women with breast cancer. Methods and Materials: From 2012 to 2014, 18 women (stage IIA-IIIB) requiring RNI prospectively enrolled on a pilot study. Median age was 51.8 years (range, 42-73 years). The cohort included breast-conserving therapy (BCT) and mastectomy patients and right- and left-sided cancers. Treatment targets and organs at risk were delineated on computed tomography scans, and PT and conventional plans were developed. Toxicity was prospectively recorded using Common Terminology Criteria for Adverse Events version 4.0. A Wilcoxon signed-rank sum test compared the dose-volume parameters. The primary endpoint was a reduction in cardiac V5. Results: Median follow-up was 20 months (range, 2-31 months). For all patients, the PT plan better met the dosimetric goals and was used for treatment. Proton therapy alone was used for 10 patients (9 postmastectomy, 1 after BCT) and combined proton–photon in 8 (6 BCT, 2 postmastectomy with immediate expander reconstruction). Proton therapy improved coverage of level 2 axilla (P=.0005). Adequate coverage of internal mammary nodes was consistently achieved with PT (median D95, 50.3 Gy; range, 46.6-52.1 Gy) but not with conventional radiation therapy (median D95, 48.2 Gy; range, 40.8-55 Gy; P=.0005). Median cardiac V5 was 0.6% with PT and 16.3% with conventional radiation (P<.0001). Median ipsilateral lung V5 and V20 were improved with PT (median V5 35.3% vs 60.5% [P<.0001]; and median V20, 21.6% vs 35.5% [P<.0001]). Grade 3 dermatitis developed in 4 patients (22%), which was the only grade 3 toxicity. No grade 4+ toxicities developed. Conclusion: Proton therapy for RNI after mastectomy or BCT significantly improves cardiac dose, especially for left-sided patients, and lung V5 and V20 in all patients without excessive acute toxicity

Transforaminal Percutaneous Endoscopic Discectomy and Foraminoplasty after Lumbar Spinal Fusion Surgery.

Wu, Jian-Jun; Chen, Hui-Zhen; Zheng, Changkun

2017-07-01

The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain. The authors, having limited their practice to endoscopic surgery over the last 10 years, report on their experience gained during that period to relieve pain by transforaminal percutaneous endoscopic revision of lumbar spinal fusions. To assess the effectiveness of transforaminal percutaneous endoscopic discectomy and foraminoplasty in patients with pain after lumbar spinal fusion. Retrospective study. Inpatient surgery center. Sixteen consecutive patients with pain after lumbar spinal fusions presenting with back and leg pain that had supporting imaging diagnosis of foraminal stenosis and/or residual/recurrent disc herniation, or whose pain complaint was supported by relief from diagnostic and therapeutic injections, were offered percutaneous transforaminal endoscopic discectomy and foraminoplasty over a repeat open procedure. Each patient sought consultation following a transient successful, partially successful or unsuccessful open lumbar spinal fusions treatment for disc herniation or spinal stenosis. Endoscopic foraminoplasty was also performed to either decompress the bony foramen in the case of foraminal stenosis, or to allow for endoscopic visual examination of the affected traversing and exiting nerve roots in the axilla. The average follow-up time was 30.3 months, minimum 12 months. Outcome data at each visit

SU-F-I-27: Measurement of SAR and Temperature Elevation During MRI Scans

Seo, Y [Korea Research Institute of Standards and Science, Daejeon (Korea, Republic of)

2016-06-15

Purpose: The poor reliability and repeatability of the manufacturer-reported SAR values on clinical MRI systems have been acknowledged. The purpose of this study is to not only measure SAR values, but also RF-induced temperature elevation at 1.5 and 3T MRI systems. Methods: SAR measurement experiment was performed at 1.5 and 3T. Three MRI RF sequences (T1w TSE, T1w inversion recovery, and T2w TSE) with imaging parameters were selected. A hydroxyl-ethylcelluose (HEC) gelled saline phantom mimicking human body tissue was made. Human torso phantom were constructed, based on Korean adult standard anthropometric reference data (Fig.1). FDTD method was utilized to calculate the SAR distribution using Sim4Life software. Based on the results of the simulation, 4 electrical field (E-field) sensors were located inside the phantom. 55 Fiber Bragg Grating (FBG) temperature sensors (27 sensors in upper and lower cover lids, and one sensor located in the center as a reference) were located inside the phantom to measure temperature change during MRI scan (Fig.2). Results: Simulation shows that SAR value is 0.4 W/kg in the periphery and 0.001 W/kg in the center (Fig.2). One 1.5T and one of two 3T MRI systems represent that the measured SAR values were lower than MRI scanner-reported SAR values. However, the other 3T MRI scanner shows that the averaged SAR values measured by probe 2, 3, and 4 are 6.83, 7.59, and 6.01 W/kg, compared to MRI scanner-reported whole body SAR value (<1.5 W/kg) for T2w TSE (Table 1). The temperature elevation measured by FBG sensors is 5.2°C in the lateral shoulder, 5.1°C in the underarm, 4.7°C in the anterior axilla, 4.8°C in the posterior axilla, and 4.8°C in the lateral waist for T2w TSE (Fig.3). Conclusion: It is essential to assess the safety of MRI system for patient by measuring accurate SAR deposited in the body during clinical MRI.

To investigate the value of response monitoring in both the primary tumour and axillary nodes on sequential PET/CT scans during neoadjuvant chemotherapy (NAC) for predicting complete pathological response (pCR), taking the breast cancer subtype into account. In 107 consecutive patients 290 PET/CT scans were performed at baseline (PET/CT1, 107 patients), after 2 - 3 weeks of chemotherapy (PET/CT2, 85 patients), and after 6 - 8 weeks (PET/CT3, 98 patients). The relative changes in SUVmax (from baseline) of the tumour and the lymph nodes and in both combined (after logistic regression), and the changes in the highest SUVmax between scans (either tumour or lymph node) were determined and their associations with pCR of the tumour and lymph nodes after completion of NAC were assessed using receiver operating characteristic (ROC) analysis. A pCR was seen in 17 HER2-positive tumours (65 %), 1 ER-positive/HER2-negative tumour (2 %), and 16 triple-negative tumours (52 %). The areas under the ROC curves (ROC-AUC) for the prediction of pCR in HER2-positive tumours after 3 weeks were 0.61 for the relative change in tumours, 0.67 for the combined change in tumour and nodes, and 0.72 for the changes in the highest SUVmax between scans. After 8 weeks equivalent values were 0.59, 0.42 and 0.64, respectively. In triple-negative tumours the ROC-AUCs were 0.76, 0.84 and 0.76 after 2 weeks, and 0.87, 0.93 and 0.88 after 6 weeks, respectively. In triple-negative tumours a PET/CT scan after 6 weeks (three cycles) appears to be optimally predictive of pCR. In HER2-positive tumours neither a PET/CT scan after 3 weeks nor after 8 weeks seems to be useful. The changes in SUVmax of both the tumour and axillary nodes combined correlates best with pCR.

HIGH ORIGIN OF SUPERFICIAL ULNAR ARTERY- A CASE REPORT

Directory of Open Access Journals (Sweden)

Anjana Jayakumaran Nair

2017-03-01

Full Text Available BACKGROUND High origin and superficially placed ulnar artery is a rare anatomical variant that usually arises either in the axilla or arm and runs a superficial course in the forearm, enters the hand and participates in the formation of superficial palmar arch. During routine dissection of cadavers in our department, we observed a unilateral case of high origin and superficial ulnar artery in a human male cadaver. It originated from the brachial artery in the lower third of arm 4 cm above its bifurcation. From its origin, it passed downwards along the medial aspect of forearm, superficial to the flexors, entered hand superficial to the flexor retinaculum and formed superficial palmar arch. The knowledge of existence of a superficial ulnar artery is important during vascular and reconstructive surgery and also in evaluation of angiographic images. Superficial position makes it more vulnerable to trauma and more accessible to cannulation.

Purpose: To evaluate the influence of a second radioisotope injection on the intraoperative success rate in patients with non-visualized axillary sentinel nodes (SN). Material and Methods: Altogether, 534 consecutive breast cancer patients with lymphoscintigraphy (LS) and SN biopsy and were included. An intratumoral injection of 99m Tc-labeled human albumin colloid with a median dose of 93 MBq was applied. Forty-two of the 80 patients without axillary hot spots on LS received a second tracer injection with a median dose of 70 MBq. Results: The visualization rate of axillary SN was 454/534 (85%). The intraoperative SN identification rate was 97% in patients with and 69% in patients without visualized SN in the axilla ( P <0.00005), but the success rate was higher (88%) with a second radioisotope injection than without it (47%; P <0.0002). Conclusion: The failure rate in intraoperative SN identification was minimized using a second radioisotope injection in patients without axillary SN on LS

Full Text Available The significance of breast tuberculosis is due to rare occurrence and mistaken identity with breast cancer and pyogenic breast abscess. A 70-year-old woman presented with a gradually increasing swelling in the right breast involving the outer upper quadrant since 6 months. Examination of the axilla revealed no lymphadenopathy. FNAC from the lump was inconclusive. Straw-colored discharge from the FNAC site was negative for acid-fast bacilli on Z-N staining and on culture. Modified radical mastectomy was done since malignancy could not be ruled out. Histopathology showed features of granulomatous mastitis. Lymph nodes recovered from the specimen showed caseation necrosis. Anti-tubercular treatment was given to the patient, and she has remained asymptomatic over 1 year of follow-up so far. Extrapulmonary tuberculosis occurring in the breast is extremely rare and is uncommon even in countries where the incidence of pulmonary and extrapulmonary tuberculosis is high.

Full Text Available The genera Malassezia and Candida include yeasts which are members of the normal mycobiota of the skin and mucosal sites of humans and other warm-blooded animals. These yeasts are associated with a variety of dermatological disorders and also systemic diseases in humans and other animals. This study confirms the occurrence of Malassezia and Candida species in healthy dogs. Samples were collected from different body sites: external ear canal, interdigital area, skin of the axilla and of the neck, and the oral and rectal mucosae. The isolates were identified using phenotypic methods (biochemical-physiological and morphological characteristics. The presence of yeasts were investigated in the specimens from 70 healthy dogs. Malassezia species were isolated in 44 dogs from which 84 Malassezia isolates were obtained. Only one Candida isolate was obtained from the dogs examined. It was found that Candida does not occur in dogs normally and Malassezia was the main colonizing yeast in healthy dogs.

Three patients with chronic radiation ulcer treated with free musculocutaneous flap transfer are described. The first patient was a 66-year-old woman who developed sacral ulcer 7 years after radiation combined with surgery for uterine cancer. After debridement of this ulcer, interpositional vein grafts 30 cm in length was used to reconstruct an 'extended' latissimus dorsi musculocutaneous flap. The second patient was a 62-year-old woman. She developed ulcer on her chest 15 years after postoperative irradiation for breast cancer. Radiation damage extended to the myocardium and pulmonary parenchyma. After careful debridement, reconstruction was performed by using the free rectus abdominis musculocutaneous flap. The last patient was a 72-year-old woman. Ulcer of the right axilla developed 19 years after postoperative irradiation for breast cancer. Reconstruction was performed by using a free rectus abdominis musculocutaneous flap. In these patients in whom radiation-damaged tissue was not completely excised, favorable results could be attained by using the transfer of the free musculocutaneous flaps. (N.K.)

Purpose: To study the CT signs of breast diseases, and discuss the value of CT in the diagnosis of breast cancer and the axillary lymph node (LN) metastases. Materials and methods: Fifty three cases were reported, including breast cancer 30 cases and benign diseases 23 cases. CT were performed in all patients, 44 also had mammography examination. Results: (1) The CT appearance of breast cancer: round or irregular mass, spiculate border, duct retraction, involved Cooper's ligament, deformed adipose space etc. Benign hyperplasia: Irregular mass and symmetrical thickening of breast glands. Cystic hyperplasia: typically multiple, round, liquid-density mass. (2) CT was comparable to mammography in terms of differential diagnosis, however with breast mass located near the axilla or for evaluation of the thoracic wall. CT was superior to mammography. CT was also helpful in detecting LN metastases. Conclusion: CT is valuable in detecting and differentiating breast diseases as well as in the diagnosis of LN metastases

Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.

Fibromatosis or desmoid tumor of the breast is a rare benign entity that has no metastatic potential but has significant risk of local recurrence. Its association with previous surgical or accidental trauma and Gardner's syndrome has been reported. Awareness of this lesion is important as the diagnosis is often confused with breast carcinoma. We report a case of a 44-year-old woman who presented with a palpable mass in her left breast, close to the axilla since a few months ago. She had undergone excisional biopsy for her left breast mass 15 months ago, and the diagnosis was confirmed as intraductal papilloma with atypical ductal hyperplasia. Subsequent ultrasound and core needle biopsy revealed stromal fibrosis. After 9 months, the mass showed an increase in its size and the anteroposterior to width ratio on ultrasonography compared to the previous examination, and final excisional biopsy confirmed the diagnosis of desmoid-type fibromatosis.

d-Penicillamine induced elastosis perforans serpiginosa with involvement of glans penis

Directory of Open Access Journals (Sweden)

2014-06-01

Full Text Available Elastosis perforans serpiginosa (EPS is an unusual perforating disorder characterized by extrusion of altered elastic fibers through the epidermis. Clinically, it presents as keratotic papules with a tendency for serpiginous or annular distribution that most commonly involves the sides of the neck and the back. However, involvement of the penis has rarely been reported. We present a case of EPS involving the neck, axilla, and glans penis in a 42-year-old man who had received long-term d-penicillamine treatment for Wilson disease. Skin biopsy revealed perforating channels containing numerous altered elastic fibers, with a characteristic “bramble brush” or “lumpy-bumpy” appearance as demonstrated by an elastin stain. The latter is thought to be pathognomonic for penicillamine-induced degenerative elastosis. These degenerative changes occurring in glans penis have rarely been described in the literature. Prompt recognition of the rare presentation could lead to early discontinuation of the offending drug, to prevent further sequelae.

Understanding upper limb strength requirements for daily tasks is imperative for early detection of strength loss that may progress to disability due to age or rotator cuff tear. We quantified shoulder strength requirements for 5 upper limb tasks performed by 3 groups: uninjured young adults and older adults, and older adults with a degenerative supraspinatus tear prior to repair. Musculoskeletal models were developed for each group representing age, sex, and tear-related strength losses. Percentage of available strength used was quantified for the subset of tasks requiring the largest amount of shoulder strength. Significant differences in strength requirements existed across tasks: upward reach 105° required the largest average strength; axilla wash required the largest peak strength. However, there were limited differences across participant groups. Older adults with and without a tear used a larger percentage of their shoulder elevation (p functional tasks to effectively detect early strength loss, which may lead to disability.

Acute Truncal Lymphedema Secondary to Axillary Metastatic Melanoma Presenting Like Cellulitis

2017-01-01

Full Text Available There are reported cases of diphencyprone used in treating cutaneous metastases of melanoma. Here, we report a patient with previous primary melanoma on his left back treated with surgical excision and lymphadenectomy, followed by radiotherapy for the recurrent tumor on the primary site. Despite radiotherapy and treatment with dabrafenib and trametinib, in-transit metastases have developed and topical diphencyprone was applied to these metastases. Six weeks later, the patient developed fever and a spreading erythematous tender indurated plaque covering the left side of the body including axillae, back, and flank, clinically suggestive of cellulitis. Systemic antibiotic therapy did not improve the condition and a biopsy showed sparse lymphocytic infiltrate. With the diagnosis of possible acute lymphedema, a CT scan was requested that showed significant axillary lymph node metastasis. The fever was considered secondary to dabrafenib and trametinib therapy. This case highlights that, in patients with lymphadenectomy, atypical forms of lymphedema on the body may appear. Truncal lymphedema is an infrequent event.

Little data is available on the epidemiology of Staphylococcus aureus in Africa. In the present study we aim at characterizing the population structure of S. aureus in healthy subjects from a rural and a semi-urban area in Lambaréné, Gabon as well as in hospital staff and inpatients. In total, 500 subjects were screened for S. aureus colonization of the nares, axillae and inguinal region. Overall, 146 (29%) were positive. We found 46 different spa types. The most frequent spa types were t084 (35%) and the agr II was the most prevalent subtype of the accessory gene regulator (56%, n=82). Five isolates (3%) were methicillin resistant S. aureus (MRSA). Carriage rates of S. aureus in Gabon are comparable to developed countries. MRSA is for the first time described and could pose a significant health threat in this region with limited access to microbiological laboratory facilities and to adequate antimicrobial agents.

Full Text Available Extensive pure peripheral venous malformations are rare. We report occurrence of peripheral venous malformations associated with pulmonary hypertension in a middle-aged male, who had nodular, irregular, soft, compressible, painless, non-pulsatile swellings over dependant positions such as forearms, hands, axilla, and genitalia, with overgrowth of hands and fingers enlarging slowly since early childhood. He had right ventricular failure signs. Plain films showed soft-tissue mass with diffuse calcifications (phleboliths. Doppler study showed low flow vascular channels, compressible hypoechoic lesions along with occasional hyperechoeic lesion corresponding with phleboliths. Magnetic resonance imaging (MRI, T1-weighted showed polypoidal mass with heterogenous hypo to intermediate signal with no flow voids. T2-weighted MRI showed high-signal intensity mass. Computed tomography (CT pulmonary angiogram showed pulmonary hypertension, no thrombi or vascular malformation. He was treated with angiotensin-converting enzyme inhibitors, diuretics, amiodarone, antiplatelets, and venous stockings. Specific therapy such as sclerosis and surgical resection could not be done as he was discharged against medical advice.

Childhood burns in south eastern Nigeria.

In a ten year retrospective study of burns in children in University of Calabar Teaching Hospital (UCTH), Calabar, the main causes were hot water, hot soup or oil (56.6%) involving children mostly in the one to three year age group. The relative safety of the home environment seen in other forms of paediatric trauma is not observed in burns in children. A changing pattern of burns in children has emerged within the region with naked flames/bush fire coming second and affecting 22.7% of the children. Chemical burns hitherto a rare occurrence is now frequent because of the storage of caustic soda and acids in living rooms by soap making parents. Burns affecting the perineum, axilla and buttocks are difficult to keep clean and frequently lead to infections, with associated increased morbidity. Causes of childhood burns are largely preventable requiring active social/medical education and public enlightenment campaigns on the various methods of prevention.

The influence of postoperative radiation therapy on development of late arm lymphedema and shoulder joint disability following mastectomy was evaluated from a series of 57 women with operable carcinoma of the breast. The patients were divided into three groups. Common for all three groups was mastectomy and partial axillary dissection. In addition one group received postoperative irradiation plus systemic therapy and another group systemic therapy alone. The incidence of late arm lymphedema/impaired shoulder mobility was 11%/4% in the group of patients undergoing surgery alone, 46%/38% in the group of patients receiving adjuvant irradiation and 6%/12% in the group of patients receiving adjuvant systemic therapy. It is concluded that adjuvant irradiation to the axilla in patients with metastatic lymph nodes highly increases the risk of late physical sequelae following modified radical mastectomy. Adjuvant systemic therapy can be administered to high risk patients without increasing the risk of late arm lymphedema and shoulder disability. (orig.)

Radiation therapy to the breast following breast conservation surgery has been the standard of care since randomized trials demonstrated equivalent survival compared to mastectomy and improved local control and survival compared to breast conservation surgery alone. Recent controversies regarding adjuvant radiation therapy have included the potential role of additional radiation to the regional lymph nodes. This review summarizes the evolution of regional nodal management focusing on 2 topics: first, the changing paradigm with regard to surgical evaluation of the axilla; second, the role for regional lymph node irradiation and optimal design of treatment fields. Contemporary data reaffirm prior studies showing that complete axillary dissection may not provide additional benefit relative to sentinel lymph node biopsy in select patient populations. Preliminary data also suggest that directed nodal radiation therapy to the supraclavicular and internal mammary lymph nodes may prove beneficial; publication of several studies are awaited to confirm these results and to help define subgroups with the greatest likelihood of benefit.

The imaging features of extensive lipofibromatosis presenting in a 1-day-old female infant are reported. This lesion involved her entire right upper limb, extending from the axilla to the palm of the hand. Radiographs showed marked deformity and thinning of all the right upper-limb bones due to pressure effect of soft-tissue enlargement, especially affecting the distal humerus and proximal forearm bones. Magnetic resonance imaging showed a huge soft-tissue mass infiltrating most of the muscles of the entire upper limb, with bony erosion. The mass was largely T1-isointense, moderately T2-hyperintense and showed marked enhancement. There were intra-lesional signal changes consistent with fatty elements. A lesion debulking procedure was performed and the histology was that of lipofibromatosis. The limb was found to be non-viable after the procedure and a subsequent above-elbow amputation was performed. Although the resection margins were not clear, she had no further recurrence over a subsequent 3-year follow-up period. (orig.)

1988-01-01

In a retrospective review of 155 children with tracheobronchial foreign body aspiration (FBA) at LeBonheur Children's Hospital in Memphis, ten patients had pneumomediastinum (PMD) on an initial chest radiograph. Nine of ten presented with PMD, and one had PMD noted after bronchoscopy. In nine, the aspirated object was a nut. In addition to PMD, atelectasis was present in three patients; associated unilateral hyperinflation was present in three, and pneumothorax was present in one patient. In nine patients, PMD was extensive and was associated with obvious interstitial emphysema extending into the axilla or lower neck. Eight patients were less than 2 years of age. In young children, FBA is the most important cause of PMD, as it is relatively common and completely curable. In a child less than 2 years of age with no history of trauma, the radiographic finding of PMD should be considered to be due to FBA until proved otherwise

Merkel cell carcinoma is a rare cutaneous, aggressive tumor. Although it shares many neuroendocrine features with small cell lung carcinoma, it has only occasionally been reported with paraneoplastic neurological syndromes. A healthy 67-year-old man developed acute ataxia, vertigo, and nausea. Subsequently he also developed dysarthria, diplopia, xerostomia, fatigability and progressive anorexia. He underwent a full diagnostic workup and was found to have a high titer of voltage-gated calcium channel antibodies in serum and cerebrospinal fluid, neurophysiological findings compatible with Lambert-Eaton myasthenia and neurological signs compatible with cerebellar degeneration. A positron emission tomography study revealed a hypermetabolic lesion in the axilla, subsequently biopsied and consistent with Merkel cell carcinoma. In most previous reports, neurological symptoms preceded the Merkel cell carcinoma diagnosis, and the primary localization was in lymph nodes. This tumor should be considered in patients with paraneoplastic syndrome, and particularly Lambert-Eaton myasthenia after exclusion of small cell lung carcinoma.

A case of multisystem Langerhans cell histiocytosis with pituitary involvement nearly 20 years after initial presentation. A 48-year-old man had histiocytosis X 22 years ago initially involving the groin; subsequently his external auditory meatus, scalp, gum, mandibular bone, perineum and axilla were involved and treated. The pituitary gland was involved 4 years ago. A thyrotropin-releasing hormone test showed delayed response suggestive of hypothalamic disease. Prolactin levels were normal. A gonadotropin-releasing hormone test showed impaired testosterone and gonadotrophin response in keeping with pituitary disease. A glucagon stimulation test showed an impaired growth hormone response but a normal cortisol increase. MRI pituitary showed an empty sella. There was no evidence of diabetes insipidus. Bone mineral densitometry was normal. He has partial hypopituitarism needing thyroxine and testosterone replacement. He also developed type 2 diabetes mellitus 9 years ago. He is closely monitored for any development of diabetes insipidus and the need for growth hormone supplementation. PMID:22715201

To investigate the value of response monitoring in both the primary tumour and axillary nodes on sequential PET/CT scans during neoadjuvant chemotherapy (NAC) for predicting complete pathological response (pCR), taking the breast cancer subtype into account. In 107 consecutive patients 290 PET/CT scans were performed at baseline (PET/CT1, 107 patients), after 2 - 3 weeks of chemotherapy (PET/CT2, 85 patients), and after 6 - 8 weeks (PET/CT3, 98 patients). The relative changes in SUVmax (from baseline) of the tumour and the lymph nodes and in both combined (after logistic regression), and the changes in the highest SUVmax between scans (either tumour or lymph node) were determined and their associations with pCR of the tumour and lymph nodes after completion of NAC were assessed using receiver operating characteristic (ROC) analysis. A pCR was seen in 17 HER2-positive tumours (65 %), 1 ER-positive/HER2-negative tumour (2 %), and 16 triple-negative tumours (52 %). The areas under the ROC curves (ROC-AUC) for the prediction of pCR in HER2-positive tumours after 3 weeks were 0.61 for the relative change in tumours, 0.67 for the combined change in tumour and nodes, and 0.72 for the changes in the highest SUVmax between scans. After 8 weeks equivalent values were 0.59, 0.42 and 0.64, respectively. In triple-negative tumours the ROC-AUCs were 0.76, 0.84 and 0.76 after 2 weeks, and 0.87, 0.93 and 0.88 after 6 weeks, respectively. In triple-negative tumours a PET/CT scan after 6 weeks (three cycles) appears to be optimally predictive of pCR. In HER2-positive tumours neither a PET/CT scan after 3 weeks nor after 8 weeks seems to be useful. The changes in SUVmax of both the tumour and axillary nodes combined correlates best with pCR.

Some of the most debilitating morbidity after surgery and radiotherapy for breast cancer is related to treatment of the axilla. This includes persistent arm lymphoedema, impaired shoulder mobility and brachial plexopathy. Considerable research efforts have been carried out on the radiation pathogenesis and the clinical radiobiology of these clinical endpoints, which has enabled their severity and incidence to be minimized. It is clear that the radiation dose-response relationships for these late endpoints are very steep. In other words, even small changes in the exact dose fractionation and physical dose distribution can cause major changes in toxicity. In particular, in many treatment schedules dose fractions larger than 2 Gy have been used without a sufficient reduction in total dose to avoid increased late effects. This is important, as much of the available literature reports side effects after suboptimal dose-fractionation schedules of side effects guaranteed and the locoregional lymphanot representative of what can be achieved using modern radiotherapy. An interesting parallelism to the problems encountered in reviewing historical experience is found in the British breast litigation, the current status of which is presented in this article. Furthermore, morbidity after radiotherapy is strongly influenced by concomitant surgery and/or chemotherapy, and this should be allowed for when designing the overall treatment. Apart from other therapeutic modalities, it has been suggested that other exogenous factors have an influence on the risk of radiotherapy-related morbidity. However, patients' age and, in the case of lymphoedema, also obesity are the only factors that have been established with some certainty. Routine adjustment of radiotherapy dose in these cases is not recommended. Two current developments may strengthen the role of radiotherapy in the treatment of breast cancer. Sentinel node biopsy may allow nodal staging without major surgical excision of

Endoscopic surgery for treatment of thyroid and parathyroid pathologies is increasingly gaining attention. The da Vinci system has already been widely used in different fields of medicine and quite recently in thyroid and parathyroid surgery. Herein, we report about modifications of the transaxillary approach in endoscopic surgery of thyroid and parathyroid gland pathologies using the da Vinci system. 16 patients suffering from struma nodosa in 14 cases and parathyroid adenomas in two cases were treated using the da Vinci system at the ENT Department of Homburg/Saar University and in cooperation with the Department of General Surgery in New Sant'Agostino Hospital, Modena/Italy. Two different retractors, endoscopic preparation of the access and three different incision modalities were used. The endoscopic preparation of the access allowed us to have a better view during preparation and reduced surgical time compared to the use of a headlamp. To introduce the da Vinci instruments at the end of the access preparation, the skin incisions were over the axilla with one incision in eight patients, two incisions in four patients and three incisions in a further four patients. The two and three skin incisions modality allowed introduction of the da Vinci instruments without arm conflicts. The use of a new retractor (Modena retractor) compared to a self-developed retractor made it easier during the endoscopic preparation of the access and the reposition of the retractor. The scar was hidden in the axilla and independent of the incisions selected, the cosmetic findings were judged by the patients to be excellent. The neurovascular structures such as inferior laryngeal nerve, superior laryngeal nerve and vessels, as well as the different pathologies, were clearly 3D visualized in all 16 cases. No paralysis of the vocal cord was observed. All patients had a benign pathology in their histological examination. The endoscopic surgery of the thyroid and parathyroid gland can be

In survivors of Ebola virus disease, clinical sequelae including uveitis, arthralgia, and fatigue are common and necessitate systematic follow-up. However, the infection risk to health-care providers is poorly defined. Here we report Ebola virus RT-PCR data for body site and fluid samples from a large cohort of Ebola virus survivors at clinic follow-up. In this cross-sectional cohort study, consecutive survivors of Ebola virus disease attending Kerry Town survivor clinic (Freetown, Sierra Leone), who had been discharged from the Kerry Town Ebola treatment unit, were invited to participate. We collected and tested axillary, blood, conjunctival, forehead, mouth, rectal, semen, urine, and vaginal specimens for presence of Ebola virus using RT-PCR. We regarded samples to be positive for Ebola virus disease if the cycle threshold was 40 or lower. We collected demographic data from survivors of their age, sex, time since discharge from the treatment unit, and length of acute admission in the Ebola treatment unit using anonymised standard forms. Between April 2, and June 16, 2015, of 151 survivors of Ebola virus disease invited to participate, 112 (74%) provided consent. The median age of participants was 21·5 years (IQR 14-31·5) with 34 (30%) participants younger than 16 years. 50 (45%) of 112 participants were male. We tested a total of 555 specimens: 103 from the axilla, 93 from blood, 92 from conjunctiva, 54 from forehead, 105 from mouth, 17 from the rectum, one from semen, 69 from urine, and 21 from the vagina. The median time from Ebola treatment unit discharge to specimen collection was 142 days (IQR 127-159). 15 participants had a total of 74 swabs taken less than 100 days from discharge. The semen sample from one participant tested positive for Ebola virus at 114 days after discharge from the treatment unit; specimens taken from the axilla, blood, conjunctiva, forehead, mouth, rectum, and urine of the same participant tested negative. All specimens from the

Odors emitted by human skin are of great interest to biologists in many fields; applications range from forensic studies to diagnostic tools, the design of perfumes and deodorants, and the ecology of blood-sucking insect vectors of human disease. Numerous studies have investigated the chemical composition of skin odors, and various sampling methods have been used for this purpose. The literature shows that the chemical profile of skin volatiles varies greatly among studies, and the use of different sampling procedures is probably responsible for some of these variations. To our knowledge, this is the first review focused on human skin volatile compounds. We detail the different sampling techniques, each with its own set of advantages and disadvantages, which have been used for the collection of skin odors from different parts of the human body. We present the main skin volatile compounds found in these studies, with particular emphasis on the most frequently studied body regions, axillae, hands, and feet. We propose future directions for promising experimental studies on odors from human skin, particularly in relation to the chemical ecology of blood-sucking insects.

Lymphoscintigraphy was performed at 3 and 20 hr following subcutaneous injection of 131 I anti-melanoma antibody (Fab) in 11 patients who had surgical resection of lymph nodes (neck, axilla, groin) at 24 hr for suspected metastatic melanoma. Comparable amounts of 125 I nonspecific control antibody (Fab) were co-administered. Six patients had nodal metastases and three showed positive images at both time periods. Five patients had no metastases though one was image positive. Four other nondiseased inguinal node groups were image negative. A total of 28 tumored nodes and 110 normal nodes were removed, counted and histologically examined. All metastatic tumors expressed antigen against which the specific Fab was directed. The concentrations of both specific and nonspecific Fab were similar in tumored nodes and both were significantly greater than in normal nodes showed essentially identical intranodal spatial distribution of the specific and control Fab in areas containing tumor. These preliminary results suggest the increased concentration of murine immunoglobulin (Fab) retained in diseased nodes was a nonspecific phenomenon

PAULO HENRIQUE WALTER DE AGUIAR

Full Text Available ABSTRACT Objective: to verify the agreement rate in the identification of sentinel lymph node using an autologous marker rich in hemosiderin and 99 Technetium (Tc99 in patients with locally advanced breast cancer. Methods: clinical trial phase 1, prospective, non-randomized, of 18 patients with breast cancer and clinically negative axilla stages T2=4cm, T3 and T4. Patients were submitted to sub-areolar injection of hemosiderin 48 hours prior to sentinel biopsy surgery, and the identification rate was compared at intraoperative period to the gold standard marker Tc99. Agreement between methods was determined by Kappa index. Results: identification rate of sentinel lymph node was 88.9%, with a medium of two sentinel lymph nodes per patients. The study identified sentinel lymph nodes stained by hemosiderin in 83.3% patients (n=15, and, compared to Tc99 identification, the agreement rate was 94.4%. Conclusion: autologous marker rich in hemosiderin was effective to identify sentinel lymph nodes in locally advanced breast cancer patients.

Diffuse skin thickening of the breast is produced by lymphedema usually secondary to obstruction of the axillary lymphatics. On physical examination, the affected breast is, due to increased fluid content, larger, heavier, and of higher overall density. Mammography reveals an increased coarse reticular pattern. Thickening of the skin can have many causes. It may be a result of tumor invasion or a tumor in the dermal lymphatics ; or because of lymphatic congestion through obstruction of lymphatic drainage within the breast, in the axilla, or centrally in the mediastinum. Further causes may be congestive heart failure, benign inflammation, primary skin processes such as psoriasis, or systemic diseases which involve the skin. Mammographic appearance is known to be nonspecific. Ultrasound can demonstrate skin thickening directly, but despite some reports suggesting that the cause of skin thickening can be inferred from the results of ultrasound, this is not usually of practical importance. The purpose of this study is to review the causes of skin thickening of the breast and to use mammography and US to differentiate the causes.

Studies on topical antiperspirant control of axillary hyperhidrosis.

Shelley, W B; Hurley, H J

1975-01-01

Axillary hyperhidrotics is reviewed from the standpoint of anatomical factors, physiological mechanisms and the history of methods of control. Anhydrous aluminum chloride and anhydrous zirconium tetrachloride are shown to be superior topical agents for partial control of axillary sweating when applied as a powder or in anhydrous nonreactive vehicles. Complete anhidrosis as demonstrated by sustained garment armpit dryness could be achieved in hyperhidrotics within 48 hours by the following trinary antiperspirant system: (1) a saturated solution of aluminum chloride hexahydrate or zirconyl chloride in absolute ethanol or isopropyl alcohol, (2) application to the dry axilla at times of sleep or other prolonged non-sweating period, (3) water vapor occlusion of area for 6 to 8 hours by means of Saran wrap. The hypothesis is presented that metallic antiperspirants act by reflux entrance into the terminal intraepidermal eccrine duct, slowly combining with the intraductal keratin, to produce a fibrillar contraction (super contraction) of keratin and hence functional closure, not histologically evident. This altered keratin is shed weeks later, with the consequent return of ductal patency and sweating.

Arora, Rajan; Abou-Bakr, Amany; Al Taleb, Ahmed

2013-02-01

Spontaneous infarction of fibroadenoma is an extremely rare complication in a nonpregnant/nonlactating female undergoing first-time aspiration. It can be misdiagnosed as carcinoma in all aspects of triple approach used for evaluation of patients with breast lesions. A 37-year-old woman presented to the outpatient surgical clinic with a 6-month history of a breast lump that was slowly increasing in size and had become painful during the past month. There was no history of any trauma or fine needle aspiration, and she was not pregnant or lactating. Mammogram and ultrasound revealed a 2.9-cm heterogenous hypoechoic suspicious lesion. No lymph nodes were detected in the axilla. Fine needle aspiration cytology was performed, and a diagnosis of benign breast lesion with features of infarction was rendered on cytology. The lump was excised surgically, and a histological diagnosis of infarcted fibroadenoma was made. Careful and diligent search for preserved benign epithelial cells on smears is the key to recognize this entity and avoid serious therapeutic implications.

Ninety-five percent of women have mammary tissue at the axilla. However, the fibroadenoma seldom occur in this area and there are only isolated case reports of this tumor. This paper presents a series of three cases of this rare entity. Three women came to our hospital by axillary lumps. The patients had a median age of 36 +/- 9-years-old with an average time of evolution of 34 +/- 53 months. One patient had the history of a breast phyllodes tumor previously excised, and two were nulliparous. In two cases, neither ultrasound nor mammogram gave useful information for its diagnosis. Mammary glands of all cases were normal. The tumors were firm and movable, similar to a lymphadenopathy, and one was evident. The mean tumor size was 28 +/- 18 mm; all were oval and with white appearance. Histological diagnosis for all cases was fibroadenoma. Our findings match with literature reports. The axillary fibroadenomas may occur in women aged 30 to 50-years-old, mimicking a lymphadenopathy. Finally, the ultrasound and the mammography are not useful tools for its diagnosis.

Our objective was to evaluate the impact of preoperative axillary ultrasound and core needle biopsy (CNB) on breast cancer treatment decision making. A secondary aim was to evaluate the impact on the utility of intraoperative sentinel lymph node (SLN) frozen section. A review of 84 patients with clinically negative axilla who underwent axillary ultrasound was performed. Sensitivity, specificity, and positive/negative predictive value for axillary ultrasound with CNB was calculated. Thirty-one (37%) had suspicious nodes. Of 27 amenable to CNB, 12 (14%) were malignant, changing treatment plans. The sensitivity of ultrasound and CNB was 54% and specificity 100%; the positive and negative predictive values were 100% and 80%, respectively. In 41 patients with normal ultrasounds who underwent SLN frozen section, 10 (24%) were positive. Preoperative axillary ultrasound impacts treatment decision making in 14%. With a sensitivity of 54%, it is a useful adjunct to, but not replacement for, SLN biopsy. Frozen section remains of utility even after a negative axillary ultrasound. Copyright © 2012 Elsevier Inc.

Full Text Available Breast cancer is a significant health problem worldwide and is one of the leading causes of cancer-related mortality in women. Preoperative chemotherapy has become the standard of care for patients with locally advanced disease and is being used more frequently in patients with early-stage breast cancer. Sentinel lymph node biopsy has shown great promise in the surgical management of breast cancer patients, but its use following preoperative chemotherapy is yet to be determined. Eleven studies have been published with respect to the accuracy of sentinel lymph node biopsy following neoadjuvant chemotherapy. Ten studies showed favourable results, with the ability to identify a sentinel lymph node in 84% to 98% of cases, and reported false negative rates ranging from 0% to 20%. The accuracy of sentinel lymph node biopsy following preoperative chemotherapy for breast cancer ranges from 88% to 100%, with higher rates when specific techniques and inclusion criteria are applied. The published literature supports the use of sentinel lymph node biopsy for assessment of the axilla in patients with clinically node-negative disease following preoperative chemotherapy.

Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that has become increasingly prominent in hospitals and the community. HIV-positive patients may be one of the most MRSA-susceptible populations because of their immunocompromised status. At the Communicable Disease Centre, Tan Tock Seng Hospital, Singapore, we implemented a universal MRSA screening program and performed a case-control study to identify risk factors for MRSA colonization among 294 HIV patients at admission from January 2009 to January 2010. Among 54 HIV-positive patients who were MRSA positive at hospital admission, 16 (29.6%) were positive at the nares/axilla/groin (NAG; one combined swab), 14 (25.9%) were NAG and perianal positive, 3 (5.6%) were NAG and throat positive, 10 (18.5%) were NAG, perianal, and throat positive, 6 (11.1%) were throat positive, and 5 (9.3%) were perianal positive. Upon multivariate analysis, we found that age [odds ratio (OR)=1.04, 95% confidence interval (CI): 1.01-1.07, p=0.006] and CD4 count hospital admission.

Canine vesicular cutaneous lupus erythematosus (VCLE) is an autoimmune skin disease of the Shetland sheepdog and rough collie, which manifests as an erosive dermatitis of sparsely haired skin of the ventrum and concave pinnae. Reported treatment consists of immunosuppression with glucocorticoids alone or in combination with azathioprine, but successful treatment is unpredictable. To report on the treatment of VCLE in a Border collie dog with topical 0.1% tacrolimus and nicotinamide in combination with tetracycline. An 8-year-old male neutered Border collie was presented with multiple coalescing erosions on the ventral abdomen, groin and axillae and ulceration on the oral commissures. Clinical presentation, routine diagnostics, histology and immunohistochemistry were consistent with VCLE. Remission was achieved with topical 0.1% tacrolimus and combination therapy of nicotinamide and tetracycline. This dog responded well to treatment with topical 0.1% tacrolimus, nicotinamide-tetracycline and sun avoidance. Complete remission was achieved after 2.5 months, and the dog was lesion free during a 1 year follow-up period. © 2013 ESVD and ACVD.

Suppression of microbial metabolic pathways inhibits the generation of the human body odor component diacetyl by Staphylococcus spp.

Directory of Open Access Journals (Sweden)

Takeshi Hara

Full Text Available Diacetyl (2,3-butanedione is a key contributor to unpleasant odors emanating from the axillae, feet, and head regions. To investigate the mechanism of diacetyl generation on human skin, resident skin bacteria were tested for the ability to produce diacetyl via metabolism of the main organic acids contained in human sweat. L-lactate metabolism by Staphylococcus aureus and Staphylococcus epidermidis produced the highest amounts of diacetyl, as measured by high-performance liquid chromatography. Glycyrrhiza glabra root extract (GGR and α-tocopheryl-L-ascorbate-2-O-phosphate diester potassium salt (EPC-K1, a phosphate diester of α-tocopherol and ascorbic acid, effectively inhibited diacetyl formation without bactericidal effects. Moreover, a metabolic flux analysis revealed that GGR and EPC-K1 suppressed diacetyl formation by inhibiting extracellular bacterial conversion of L-lactate to pyruvate or by altering intracellular metabolic flow into the citrate cycle, respectively, highlighting fundamentally distinct mechanisms by GGR and EPC-K1 to suppress diacetyl formation. These results provide new insight into diacetyl metabolism by human skin bacteria and identify a regulatory mechanism of diacetyl formation that can facilitate the development of effective deodorant agents.

2018-05-01

Many dermatologic procedures are painful and can be distressing to patients. To determine whether nitrous oxide has been used in dermatology and whether literature supports its use in terms of providing analgesia and anxiety associated with dermatologic procedures. A search of PubMed and Cochrane databases was conducted through July 15, 2016, to identify studies involving nitrous oxide use in dermatology. Eight studies were identified and reviewed. The use of nitrous oxide/oxygen mixture resulted in a significant reduction in pain when used for photodynamic therapy, botulinum toxin therapy for hyperhidrosis of both the palms and axilla, aesthetic procedures involving various laser procedures, and in the treatment of bed sores and leg ulcers. However, pain scores were higher when nitrous oxide/oxygen was used in the debridement of chronic ulcers when compared with the use of topical anesthesia. In addition, nitrous oxide has been reported effective at reducing pain in hair transplants, dermabrasion, excision and repairs, and pediatric procedures. Current literature provides some evidence that nitrous oxide, used alone or as adjunct anesthesia, is effective at providing analgesia for many dermatologic procedures. Nitrous oxide has many potential applications in dermatology; however, further evidence from randomized controlled trials is needed.

A 2-yr-old, captive, intact female Virginia opossum ( Didelphis virginiana ) with a 7-mo history of ulcerative dermatitis and weight loss was euthanatized for progressive worsening of clinical signs. Initially the opossum was treated with several courses of antibiotics, both topically and systemically; systemic nonsteroidal anti-inflammatory medication; and, later, systemic glucocorticoids, with no improvement in clinical signs. Histopathologic samples of skin lesions taken 3 mo into the course of disease revealed no evidence of neoplasia; however, cytologic samples of a skin lesion taken 5 mo into the course of disease revealed mature lymphocytes, and were suggestive of cutaneous lymphoma. Postmortem histopathology revealed neoplastic cells consistent with lymphoma; these were found in the haired skin of the forearm, axilla, hind limb, face, and lateral body wall, as well as the liver, kidney, axillary lymph node, heart, and spleen. Multifocal neutrophilic and eosinophilic ulcerative and necrotizing dermatitis and folliculitis of the haired skin were also present. To the authors' knowledge, this is the first documented case of cutaneous lymphoma in a Virginia opossum and the first documented case with visceral metastases in a marsupial.

Objective: to explore the changes and the tendency of breast cancer radiotherapy in China within the past decade. Methods: A survey on breast cancer radiotherapy in 1999 and 2006 was conducted in 4 hospitals located within the southeast coastal region of China, including patients' clinical characteristics, the purpose of radiotherapy and its techniques. Results: The percentage of breast conservative treatment (BCT) increased from 3% in 1999 to 13% in 2006. For radiotherapy techniques in 2066 compared with 1999, the growth trend was found in use of breast immobilization devices (80% vs. 46%), treatment planning system (70% vs. 23%), and CT simulation (14% vs. 0). The frequency was increased in the chest wall irradiation after mastectomy (90% vs. 67%), but decreased in internal mammary region (30% vs. 76%) and axilla (37% vs. 69%) treatment. There were no differences in total dose and fractionation prescription. Conclusions: BCT was performed more frequently, but post-mastectomy radiotherapy was still essential option in China at present. Although some advanced techniques were applied frequently in clinical practice. Simulation, treatment planning, and irradiation target design were urgent for improvement and standardization.

To assess how accurately the sentinel lymph node (SLN) can be identified percutaneously, using gamma probe and ultrasound technology. Women with breast cancer, scheduled for wide local excision or mastectomy with SLN biopsy (SLNB), were included. Peri-areolar intradermal injection of technetium-99 nanocolloid was performed on the morning of surgery and 1-2 ml of blue dye was injected in the peri-areolar region once the patient was anaesthetized. Prior to surgery, a gamma probe was used over the skin to identify any hot spot that could represent a SLN. Ultrasound, guided by the hot spot, was then used to visualize potential SLNs and guide the insertion of a localizing wire. The accuracy in localizing the SLN by preoperative gamma-probe guided ultrasonography was assessed by comparison to SLNB. A SLN was correctly identified and marked using gamma-probe guided ultrasonography in 44 of 59 cases (75%; 95% CI: 63-86%). This study supports the case for investigating percutaneous gamma probe and ultrasound guided interventions in the axilla in women with breast cancer, as a potential alternative to surgical SLNB.

Mycotic false aneurysm caused by local arterial injury from attempted intravenous injections in drug addicts remains a challenging clinical problem. The continued increase in drug abuse has resulted in an increased incidence of this problem, particularly in high-volume urban centres. In the drug-abusing population, mycotic arterial pseudoaneurysms most often occur because of missed venous injection and are typically seen in the groin, axilla, and antecubital fossa. Mycotic aneurysms may lead to life-threatening haemorrhage, limb loss, sepsis, and even death. Any soft-tissue swelling in the vicinity of a major artery in an intravenous drug abuser should be suspected of being a false aneurysm until proven otherwise and should prompt immediate referral to a vascular surgeon for investigation and management. We report a case of rupturing mycotic pseudoaneurysm of the left common femoral artery treated by surgical resection followed by vessel reconstruction with autologous material. Unfortunately, at the time of discharge a sudden leakage from the vein graft anastomosis occurred, with subsequent massive bleeding, and required emergent endovascular covered stenting. To the best of our knowledge, this is the first reported case of femoral artery bleeding in a drug abuser treated by stent graft placement.

People tend to choose perfumes to complement their body odour. As kin share some body odour qualities, their ability to select complementary perfumes for relatives might be higher compared with selection for nonrelatives. We tested this in two studies, comparing selection of a perfume for a target man by himself and by either a familiar but unrelated individual (girlfriend; Study 1) or a relative (sister; Study 2). Target men applied the two perfumes (own or other's choice) to their axillae and then wore cotton pads for 12 hr. Collected perfume-body odour blends and perfumes alone were assessed by rater panels. In Study 1, the blends were rated as nominally more pleasant when body odours were mixed with the perfumes selected by girlfriends compared with those selected by target men themselves. In Study 2, body odours mixed with perfumes selected by sisters were rated significantly more attractive than those mixed with perfumes selected by target men. No significant differences were found for attractiveness and pleasantness ratings when perfumes were rated alone, suggesting that it was the resulting blends that were uniquely different. Our results indicate that sisters might be particularly tuned to select suitable perfumes for their siblings.

Transaxillary Subcutaneouscopic Excision of Fibroadenoma of the Breast in Children: The Covert Scar Approach.

Fibroadenoma is a common condition in adolescent girls. Most tumors are excised either through a periareolar approach or the inframammary approach. Both approaches produce visible scars in adolescent girls. We propose a new cosmetic approach to this lesion and report our experience with the transaxillary subcutaneouscopic approach for excision of the fibroadenoma of the breast. The purpose of this case report is to delineate an innovative surgical approach to resection of a breast fibroadenoma that yields an adequate resection without possible damage to the ductal system while optimizing cosmetic results by avoiding scars. We retrospectively reviewed the medical records of four adolescent girls who underwent the above approach for excision of fibroadenoma of the breast. The age range was 14-16 years. There were no complications in all 4 patients. The final result at the 3-month follow-up revealed an esthetically pleasing skin incision that healed well and was hidden by the natural skin fold of the axilla. Transaxillary subcutaneouscopic excision of fibroadenoma of the breast in children is a safe and effective technique and should be considered for excision of benign breast lesions in children.

The purpose of this study was to investigate the association between selected skin-fold thicknesses and training variables with a half-marathon race time, for both male and female recreational runners, using bi- and multivariate analysis. In 52 men, two skin-fold thicknesses (abdominal and calf) were significantly and positively correlated with race time; whereas in 15 women, five (pectoral, mid-axilla, subscapular, abdominal, and suprailiac) showed positive and significant relations with total race time. In men, the mean weekly running distance, minimum distance run per week, maximum distance run per week, mean weekly hours of running, number of running training sessions per week, and mean speed of the training sessions were significantly and negatively related to total race time, but not in women. Interaction analyses suggested that race time was more strongly associated with anthropometry in women than men. Race time for the women was independently associated with the sum of eight skin-folds; but for the men, only the mean speed during training sessions was independently associated. Skin-fold thicknesses and training variables in these groups were differently related to race time according to their sex.

Nipple adenoma arising from axillary accessory breast: a case report

2012-11-01

Full Text Available Abstract Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the axillary accessory breast have very seldom been reported in the English literature. We report a case of nipple adenoma arising from axillary accessory breast including clinical and pathological findings. An 82-year-old woman presented with the complaint of a small painful mass in the right axilla. Physical examination confirmed a well-defined eczematous crusted mass that was 8 mm in size. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Microscopic structural features included a compact proliferation of small tubules lined by epithelial and myoepithelial cells, and the merging of glandular epithelial cells of the adenoma into squamous epithelial cells in the superficial epidermal layer. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for axillary tumor neoplasms.

A case of a 51-year-old woman with mastitis in her right breast 17 years after Augmentation Mammoplasty with PAAG produced in Ukraine is presented, the MRI and mammary US findings are discussed. Solid areas in the background of the non-structural gel are established, hardly to be distinguished from primary mammary lesions. At a control US examination 6 months after the surgical intervention, an increase in new l.n. in the right axilla is established. The biopsy performed discovered the histological features for follicular non-Hodgkin's lymphoma grade 2, CD 20 (+) sex. The links of the lymphoma as a systemic manifestation of the local cytotoxic effect in the C-myc gene expression of the medical polyacrylamide hydrogel is questionable. In all women after Augmentation Mammoplasty with PAAG 6-month follow-ups with US are recommended, completed with MRI if needed and, annual blood tests as well. For equivocal clinical examinations and imaging studies, proceed to a FNB or Cor biopsy under US control. Key words: Mastitis. Augmentation MAMMOPLASTY. PAAG, US. MRT.

A report of a 48 year-old male with non-Hodgkin's lymphoma of the left parotid gland (clinical stage I EA, follicular medium-sized B cell type) is presented. He was solely treated with 30 Gy of radiation to the whole neck region, bilateral paraclavicular region and the left axilla, and 10.6 Gy boost was given to the primary lesion. Five months later, facial edema and serum LDH elevation developed suddenly. Relapse of the malignant lymphoma was suspected, but a whole body CT scan failed to show this. On the contrary, the CT scan showed a diffuse hypoattenuated area of the thyroid gland. In addition to positive antibodies, i.e, antithyroglobulin and antimicrosomal antibodies, total cholesterol and other serum markers also suggested hypofunction of the thyroid due to acute exacerbation of chronic thyroiditis. Immediately after hormone-replacement therapy, his symptoms disappeared and the abnormal serum data improved. Although the relationship between chronic thyroiditis and radiation injury has not been clearly demonstrated, it seems necessary to evaluate thyroid function before radiotherapy for head and neck tumors. Patients with chronic thyroiditis should be followed carefully after radiotherapy. (author)

A variation of Musculocutaneous nerve without piercing the coracobrachialis muscle while communicating to the median nerve: A case report and literature review

Hamid Tayefi Nasrabadi

Full Text Available Introduction: Anatomical variations of the peripheral nervous system may have not any clinical signs and symptoms. One of these variations belongs to the Musculocutaneous nerve. However, a good knowledge of nerve pathways and their variations is very important for surgeons in post-traumatic evaluations, exploratory interventions, and/or administration of neuromuscular blocks in axillary region in order to surgical therapies. Presentation of case: This report describes a case of variation of the musculocutaneous nerve which was observed in an old Iranian male cadaver during routine educational dissection (Fig. 1. Discussion and Conclusion: Anatomically, in the axilla region, the Musculocutaneous nerve is originated of the lateral cord of brachial plexus, then, by piercing the coracobrachialis muscle arrives enters to anterior compartment of the arm. But, in the present report, we observed that the Musculocutaneous nerve without piercing the coracobrachialis muscle has arrived in the left arm, then communicated to the Median nerve. To exploratory interventions of the arms for peripheral nerve repair and surgical therapies, a good knowledge of nerve pathways helps to surgeons for preventing possible mistakes during surgery.

Objective: To evaluate the efficacy of hypofractionated radiotherapy (HFRT) in locoregional control (LRC) in breast cancer. Study Design: Descriptive case series. Place and Duration of Study: Oncology Department of CMH Rawalpindi, from Jan 2014 to Oct 2014. Material and Methods: Fifty three female patients with histopathologically confirmed breast cancer and Eastern Cooperative Oncology Group performance status (ECOG-PS) greater than equal to 2 were enrolled in the study. These patients required post-operative radio-therapy to intact breast/ chest wall / residual breast tissue were treated using linear accelerator. Lateral/medial tangential and ipsilateral supraclavicular fields were employed to a dose of 39 Gy in 13 fractions with 6 MV photon beam. The ipsilateral axilla was also radiated if required to same dose with postero-anterior field. Scar boost was administered using 6 MeV electron beam to a dose of 7.5 Gy in 3 fractions in patients with high risk features for local recurrence like high grade, positive axillary nodes, lymphovascular invasion and close or positive surgical resection margins. Patients were followed up weekly during radio-therapy (RT) and three monthly after completion of RT for a period of 6 months. Any suspicious lesion was subjected to biopsy. Data analysis was done with the help of the Statistical Package for the Social Sciences (SPSS) version 19 software, which included descriptive analysis. Loco-regional control (LRC) and loco-regional recurrence (LRR) rates were calculated. LRC was no recurrence of tumor/tumor control in chest wall, axilla, residual breast tissue, and/or infraclavicular/supraclavicular lymph nodes. LRR was appearance of nodules / leison at local site which was biopsied and confirmed histopathologically. Results: Fifty three female patients with histopathologically confirmed breast cancer and ECOG-PS greater than equal to 2 requiring post-operative radio-therapy to intact breast/chest wall/ residual breast tissue were

Purpose: To aim of this study was to evaluate the diagnostic accuracy of axillary lymph node sonography, if necessary in collaboration with US-guided large core biopsy, in the preoperative evaluation of breast cancer patients scheduled for quadrantectomy and sentinel lymph node excision. Materials and methods: From July 2001 to December 2002, we evaluated 117 breast cancer patients with ultrasound and, where indicated, FNAB. Breast lesions has diameters between 4 and 26 mm (mean diameter 11 mm). Fifteen (13%) of the 117 patients were excluded from the series as they did not found fulfil the criteria for preliminary sonography of the axilla: in 9 patients fewer than 4 nodes were detected and in 6 patients the breast lesions were intraoperatively found to be benign. Eleven patients (10.7%) with sonographically suspicious axillary nodes were sampled by US-guided core biopsy using a 14 or 16 Gauge Tru-Cut needle. Results: The ultrasound study aims to evaluate the dimensions and morphology of the breast lesion as well as detect and assess at least 4 axillary nodes. These were evaluated for hilar and cortical thickening and radio between the sinus diameter and the total longitudinal diameter. Lymph nodes with hilar diameters equal to or greater than 50% of the longitudinal diameter were considered normal. Of the 102 patients evaluated, 77 (75.7%) had normal axillary nodes according to the US criteria adopted. Negativity was confirmed by histology in 56 cases (72.7%, true negative); 21 (27.3%, false negative) were found to be positive, in contrast with the sonographic appearance. The false negative cases were due to lymph node micrometastasis which probably did not cause morphologic alterations perceptible at ultrasound. The remaining 25 patients (24.5%) had axillary lymph nodes classified as suspicious. In 13 cases of (52%, true positive) there was agreement with histology, whereas in 12 cases (48%, false positive) the US suspicion was not confirmed at surgery. The most

This study evaluates acute toxicity outcomes in breast cancer patients treated with adjuvant proton beam therapy (PBT). From 2011 to 2016, 91 patients (93 cancers) were treated with adjuvant PBT targeting the intact breast/chest wall and comprehensive regional nodes including the axilla, supraclavicular fossa, and internal mammary lymph nodes. Toxicity was recorded weekly during treatment, one month following treatment, and then every 6months according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Charts were retrospectively reviewed to verify toxicities, patient parameters, disease and treatment characteristics, and disease-related outcomes. Median follow-up was 15.5months. Median PBT dose was 50.4 Gray relative biological effectiveness (GyRBE), with subsequent boost as clinically indicated (N=61, median 10 GyRBE). Chemotherapy, when administered, was given adjuvantly (N=42) or neoadjuvantly (N=46). Grades 1, 2, and 3 dermatitis occurred in 23%, 72%, and 5%, respectively. Eight percent required treatment breaks owing to dermatitis. Median time to resolution of dermatitis was 32days. Grades 1, 2, and 3 esophagitis developed in 31%, 33%, and 0%, respectively. PBT displays acceptable toxicity in the setting of comprehensive regional nodal irradiation. Copyright © 2017. Published by Elsevier B.V.

Purpose: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer. Methods: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymph node using hemosiderin obtained from autologous blood injected in the periareolar region 24h before surgery on an outpatient basis. Patients received preoperative subareolar intradermal injection of Technetium-99 in the immediate preoperative period. Patients were submitted to sentinel lymph node biopsy, with incision in the axillary fold guided by Gamma-Probe, dissection by planes until the identification of the point of maximum uptake of Technetium-99, identifying the marked nodes and their colors. All surgical specimens were sent for pathological and immunohistochemical study. Results: The results showed no evidence of side effects and/or allergic and non-allergic reactions in patients submitted to SLNB with hemosiderin. The SLN identification rate per patient was 100%. SLNB identification rate per patient with hemosiderin was the same as that of Technetium, with a concordance rate of 100% between the methods. Conclusion: Hemosiderin is a safe dye that is equivalent to Technetium in breast sentinel lymph node biopsy. (author)

To evaluate radiation dose and accuracy with TLD and diode detector when treat total skin with electron beam. Using Stanford Technique, we treated patient with Mycosis Fungoides. 6 MeV electron beam of LINAC was used and the SSD was 300 cm. Also, acrylic speller(0.8 cm) was used. The patient position was 6 types and the gantry angle was 64, 90 and 116 degree. The patient's skin dose and the output were detected 5 to 6 times with TLD and diode. The deviations of dose detected with TLD from tumor dose were CA + 6%, thigh + 8%, umbilicus + 4%, calf - 8%, vertex - 74.4%, deep axillae - 10.2%, anus and testis - 87%, sole - 86% and nails shielded with 4 mm lead + 4%. The deviations of dose detected with diode were - 4.5% ∼ + 5% at the patient center and - 1.1% ∼ + 1% at the speller. The deviation of total skin dose was + 8% ∼ - 8% and that deviation was within the acceptable range(±10%). The boost dose was irradiated for the low dose areas(vertex, anus, sole). The electron beam output detected at the sootier was stable. It is thought that the deviation of dose at patient center detected with diode was induced by detection point and patient position.

A 62-year-old man with acute paraplegia was transferred to our hospital. He had flaccid paraplegia and multiple cranial nerve palsies, such as mydriasis of the left pupil, abduction palsy of the left eye, hoarseness and dysphagia, but no meningeal irritation signs. MRI of the spinal canal showed swellings of the conus medullaris and the cauda equine, and also contrast enhancement of the spinal meninges. The cerebrospinal fluid (CSF) showed pleocytosis and protein increment. The lymph node was swollen in his right axilla. The biopsy specimen from the right axillary lymph node revealed metastasis of malignant melanoma histologically. Careful check-up of his whole body found a malignant melanoma in the subungual region of the right ring finger. Repeated cytological examination revealed melanoma cells in the CSF, confirming the diagnosis of leptomeningeal melanomatosis. His consciousness was gradually deteriorated. His family members chose supportive care instead of chemotherapy or surgical therapy after full information about his conditions. Finally, he died 60 days after transfer to our hospital. This is a rare case of leptomenigeal melanomatosis presenting with acute paraplegia and multiple cranial nerve palsies. Careful follow-up and repeated studies are vital for the early diagnosis of leptomenigeal melanomatosis in spite of atypical clinical presentation.

Full Text Available Gougerot-Carteaud syndrome (GCS is a rarely seen dermatosis characterized by reticular and pigmented plaques with a tendency to merge with each other in areas such as the neck, upper body, and axilla in young adults. A 20-year-old male patient presented to the dermatology outpatient clinic with the complaints of itching and brown patches affecting the trunk, back and the neck. He had no endocrine diseases and used no drugs. Dermatological examination revealed reticulated, hyperpigmented, verrucous papules and plaques on the anterior surface of his trunk, upper back, and neck region. No fungal elements were encountered in the potassium hydroxide examination. Histopathologically, basket-like hyperkeratosis, papillomatosis, mild acanthosis, and hyperpigmentation in the basal layer were detected. Minocycline treatment was initiated at a dose of 100 mg/daily. At the three-month follow-up visit, minocycline treatment was terminated due to lack of clinical response, and 30 mg/day acitretin treatment was initiated. The lesions showed marked improvement except for a slight hyperpigmentation in the first month of the treatment. We report here a case of GCS in which acitretin was started due to clinical unresponsiveness to minocycline treatment and, substantially, a favorable result was obtained in a short time.

Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC) is a synthetic fragrance chemical and an important contact allergen, at least in Europe. Despite this importance, little is known about risk factors associated with this allergen. To examine factors from the history and clinical presentation of patch tested patients associated with HICC sensitization. Contact allergy surveillance data of 95 637 patients collected by the Information Network of Departments of Dermatology (IVDK, www.ivkd.org) in 2002-2011 were analysed. Point and interval estimates of the relative risk were derived from multifactorial logistic regression modelling. The overall prevalence of HICC sensitization was 2.24%. The strongest risk factors were polysensitization and dermatitis of the axillae, followed by dermatitis at other sites. No consistent and significant time trend was observed in this analysis. As compared with the youngest patients, the odds of HICC sensitization increased approximately three-fold in the 52-67-year age group, and strongly declined with further increasing age. The risk pattern with regard to age and affected anatomical site differed from that observed with other fragrance screening allergens. Cosmetic exposure, as broadly defined here, was a stronger and more prevalent individual risk factor than occupational exposure. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Castro-Lopes, J M; Coimbra, A

1991-03-01

The spinal cord projections of the 3 main forelimb nerves-median, radial and ulnar, were studied in the rat dorsal horn with transganglionic transport of wheat germ agglutinin-horseradish peroxidase (WGA-HRP), or using the disappearance of fluoride resistant acid phosphatase (FRAP) after nerve section. The projection patterns in lamina II were similar following the two procedures. The median and the radial nerve fibers projected to the medial and the intermediate thirds, respectively, of the dorsal horn lamina II in spinal cord segments C4-C8. The ulnar nerve projected to segments C6-C8 between the areas occupied by the other two nerves. The FRAP method also showed that the lateral part of lamina II, which was not filled by radial nerve fibers, received the projections from the dorsal cutaneous branches of cervical spinal nerves. In addition, FRAP disappeared from the medial end of segment T1 after skin incisions extending from the medial brachium to the axilla, which seemed due to severance of the cutaneous branchlets of the lateral anterior thoracic nerve. The FRAP procedure is thus sensitive enough to detect fibers in lamina II arising from small peripheral nerves, and may be used as an alternative to the anterograde tracing methods whenever there are no overlapping projections.

Full Text Available Background: Ticks are obligate blood feeders that parasitize a wide variety of animals. Hyalomma aegyptium, parasitize tortoises and other small wild life and livestock. This study was carried out to determine spur-thighed tortoise (Testudo graeca infestation to H. ageyptium in Urmia region West Azerbaijan of Iran. Methods: The study was carried out over a 16 month period from the spring of 2004 to the fall of 2005. A total of 32 tor¬toises were sampled. Results: The results indicated that 14 tortoises infected with ticks. A total of 117 ticks were collected from infested animals, the minimum and maximum tick infestation was 1-60. Ticks were attached to the axilla of fore and hind legs of tortoises. All ticks were determined to be H. aegyptium. Conclusion: H. aegyptium was the most common tick species in the study area. Due to tendency of some people to keeping tortoise as pet animal, more attention must be done to tortoise’s tick infestation. Due to existence of H. aegyptium on tor¬toises in this region more study will need to evaluate presence of this tick on other animal species and its role on transmis¬sion of diseases.

The benefit of neoadjuvant chemotherapy (NAC) in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancers and in invasive lobular carcinoma (ILC) is uncertain due to the low rates of pathologic complete response (pCR). The aim of this study was to determine if pathologic features can identify subsets likely to benefit from NAC. Patients with stage I-III ER+, HER2- breast cancer receiving NAC were retrospectively reviewed. Endpoints were downstaging to breast-conserving surgery (BCS) and nodal pCR after NAC. Patients were grouped by progesterone receptor (PR) status and grade/differentiation (high grade or poor [HP] vs. non-HP). From 2007 to 2016, 402 ER+/HER2- cancers in patients receiving NAC were identified. Median age was 50 years, 98% were clinical stage II-III, and 75% were cN+. Overall pCR rate was 5%; breast pCR in 7% and nodal pCR in 15% of cN+ patients (p benefit from NAC are those with PR- and HP tumors. Patients with ILC are unlikely to downstage in the breast or axilla compared with IDC. The use of these criteria can assist in defining the initial treatment approach.

Full Text Available Background. Breast lumps have varied pathology, and there are different techniques to prove the diagnosis. The aim of the present study is to analyze the role of fine needle aspiration cytology (FNAC of the breast lesions at our center. Methods. We had retrospectively analysed 854 patients who underwent FNAC for primary breast lumps and 190 patients who underwent FNAC for an axillary lymph node in the year 2010. Results. Of 854 patients, histological correlation was available in 723 patients. The analysis was done for 812 patients as medical records were not available for 42 patients. FNAC was false negative in seven cases; 2 cases of phyllodes were reported as fibroadenoma, and 5 cases of carcinoma were diagnosed as atypical hyperplasia. The sensitivity, specificity, and false negative value of FNAC in diagnosing breast lumps were 99% (715/723, 100%, and 1%, respectively. Of 190 patients for whom FNAC was performed for axilla, 170 had proven to have axillary lymph node metastases, and the rest had reactive hyperplasia or inflammatory cells. Conclusions. FNAC is rapid, accurate, outpatient based, and less complicated procedure and helps in diagnosis of breast cancer, benign diseases, and axillary involvement in experienced hands with less chance of false results.

To systematically analyse the literature on the use of the microwave-based device for subdermal thermolysis of the axilla and its efficacy for the treatment of axillary hyperhidrosis. A systematic review was conducted using PubMed, Embase, SCOPUS and Cochrane databases on 2 June 2016. The inclusion criteria including: (1) studies with human subjects, (2) full-text articles published in English, (3) a microwave-based device used to treat axillary hyperhidrosis and (4) trials that precisely evaluated axillary hyperhidrosis. Exclusion criteria were the following: (1) studies that did not fit the inclusion criteria mentioned above and (2) case reports and reviews. We reviewed five clinical trials and 189 patients, all of which were published between 2012 and 2016. There was one randomized controlled trial, one retrospective study and the remainder were prospective studies. Although all of the studies were conducted with a small sample size, the results indicated that microwave-based device treatment of axillary hyperhidrosis had long-term efficacy with mild adverse effects. In addition, most patients were satisfied with the outcomes in these studies. Microwave-based device treatment may be an effective alternative treatment for axillary hyperhidrosis. However, further investigation is necessary to determine its long-term efficacy and safety.

Thoracic outlet syndrome is caused by compression of the neurovascular bundle as it passes from the upper thorax to the axilla. The neurovascular bundle can be compressed by bony structures such as the first rib, cervical ribs or bone tubercles, or from soft-tissue abnormalities like a fibrous band, muscle hypertrophy or space-occupying lesion. Thoracic outlet syndrome commonly affects young adults but can be seen in the pediatric age group, especially in older children. Diagnosis is based on a holistic approach encompassing clinical features, physical examination findings including those triggered by various maneuvers, electromyography, nerve conduction studies and imaging. Imaging is performed to confirm the diagnosis, exclude mimics and classify thoracic outlet syndrome into neurogenic, arterial, venous or mixed causes. MRI and MR angiography are useful in this process. A complete MRI examination for suspected thoracic outlet syndrome should include the assessment of anatomy and any abnormalities using routine sequences, vessel assessment with the arms in adduction by MR angiography and assessment of dynamic compression of vessels with abduction of the arms. The purpose of this paper is to describe the anatomy of the thoracic outlet, causes of thoracic outlet syndrome, the MR imaging techniques used in its diagnosis and the principles of image interpretation.

Full Text Available Common causes of hiccups are over-distension of the stomach, a sudden change in gastrointestinal temperature, excessive alcohol and tobacco ingestion, and sudden excitement or emotional changes. Common presenting symptoms of sarcoidosis include cough, dyspnea, and chest pain. It is very rare for a sarcoidosis patient to present with hiccups. A 48-year-old man presented with hiccups of 2 weeks' duration. He denied having headaches, earache, cough, abdominal pain, fever, or body weight loss history. On physical examination, he had no peripheral lymphadenopathies in the neck, axilla and inguinal regions, no organomegaly in the abdomen and no skin abnormalities. A neurological examination showed normal findings. Laboratory investigations revealed a normal complete blood count, liver function, renal function, serum calcium, and tumor markers. Transabdominal ultrasound was negative, and panendoscopy revealed a small healing duodenal ulcer. Chest radiography showed an enlarged right lung hilum, while computed tomography showed enlargement of multiple mediastinal lymph nodes. Endoscopic ultrasound-guided fine-needle aspiration with a 22-gauge needle and trucut biopsy with a 19-gauge needle (quick-core biopsy needle were performed, and cytology, cell block and histology revealed non-caseating granuloma, with negative tuberculous and fungus cultures. Mediastinal lymph node due to sarcoidosis can be a rare cause of hiccups.

Fulton, E; Jan, F; Zimarowski, M J

2017-11-15

Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease usually with a neutrophil rich inflammatory infiltrate, and characterized by linear IgA deposition at the basement membrane zone (BMZ), and neutrophil predominant dermal inflammation. We report a case of LABD with numerous eosinophils and flame figure formation, a unique histopathologic finding not previously reported. A 69-year-old woman presented with a rapidly progressive, intensely pruritic rash over forearms, breasts, axillae, hips, and thighs. Thelesions were comprised of annular vesicles and bullae with hemorrhagic crusts and erosions. The clinical differential diagnosis included bullous pemphigoid(BP), LABD, and epidermolysis bullosa aquisita (EBA). A biopsy from a bullous plaque on the wrist revealed a subepidermal blister with neutrophils and numerous eosinophils with flame figure formation.Direct immunofluorescent (DIF) microscopy revealed linear deposition of IgA at the BMZ. Although unusual, the combined findings supported a diagnosis of LABD. Increased eosinophils may be associated with drug-induced LABD and may explain the numerous eosinophils in our case. It is important to be aware of this finding as the pathology may easily be misdiagnosed as BP, or possibly bullousWells syndrome. This case emphasizes that combined clinical, pathologic, and DIF findings are essential in the diagnosis of bullous dermatoses.

The method of tangential rotation therapy for non-operated breast cancer has been developed in Yonsei Cancer Center. This method is in principle to avoid the disorder of the lung field by radiotherapy as well as possible and to make an adequate radiation dosage according to each treated region, including breast, axilla, supra or infraclavicullar fossa, and sternum. We have various irradiation methods conducted today, but this continuous and repeated tangential rotation therapy is extraordinary superior to a traditional fixed tangential therapy. The advantages of this method are summarized as follows: 1) Simultaneous treatment with different dose is possible to the breast and the thorax including the sternum. 2) The radiation effect on the intrathoracic organs including lung and heart is almost absent. 3) It is easy to simultaneous irradiation in the large treated region. 4) The dose distribution of various types is possible by changed a rotation angle and an eccentric angle in accordance with irradiated region. 5) The irradiated fields are not overlapped and not so complicated as a fixed polytagential therapy. Therefor the continuous and repeated tangential rotation therapy is an adequate method for the non-operated breast cancer and may be sure of helping for radiation therapy.

Purpose: Imaging of breast tumors using MR-Elastography. Material and method: Low-frequency mechanical waves are transmitted into breast-tissue by means of an oscillator. The local characteristics of the mechanical wave are determined by the elastic properties of the tissue. By means of a motion-sensitive spin-echo-sequence these waves can be displayed within the phase of the MR image. Subsequently, these images can be used to reconstruct the local distribution of elasticity. In-vivo measurements were performed in 3 female patients with malignant tumors of the breast. Results: All patients tolerated the measurement set-up without any untoward sensation in the contact area of skin and oscillator. The waves completely penetrated the breast, encompassing the axilla and regions close to the chest wall. All tumors were localized by MRE as structures of markedly stiffer tissue when compared to the surrounding tissue. Furthermore, in one patient, a metastasis in an axillary lymph node was detected. In all patients, local regions of increased elasticity were found in the remaining parenchyma of the breast, which, however, did not reach the high levels of elasticity found in the tumors. Conclusion: MRE is an imaging modality enabling adjunct tissue differentiation of mammary tumors. (orig.) [de

Full Text Available Background. Lymphatic malformations or lymphangiomas are rare benign hamartomas that result from maldevelopment of primitive lymphatic sacs. They are most frequently found in the neck and axilla, while intra-abdominal and mediastinal lymphangiomas are uncommon. These are primarily tumours of infancy and childhood and are successfully treated with surgical excision. Summary of Cases. Five cases of lymphangioma comprising three intra-abdominal lymphangiomas and two unilateral axillary lymphangiomas presenting at one institution in Trinidad W.I. between 2005 and 2012 were examined. The presentations, location, workup, treatment, and outcome of these patients were studied. Conclusion. This paper discusses a range of extracervical lymphangioma cases seen at San Fernando General Hospital, Trinidad W.I. We report three intra-abdominal cases and the most common clinical presentations were abdominal pain and distension. Also two axillary cases were reported, which presented as painless axillary masses. The major concerns for excision of axillary lymphangioma by parents and surgeons were cosmesis and feasibility of complete resection without disruption of developing breast tissue and axillary vessels. We believe that ultrasound scan is very good at detection of the lesion, while CT is better at determining tumour content and planning for the operation. It is our opinion that complete surgical excision can be achieved.

To gain information on hair loss amongst curly coated retrievers by questionnaire and to define the clinical and pathological features of hair coat abnormalities in affected dogs in the United Kingdom and Sweden. Questionnaires were completed by members of the Curly Coated Retriever Clubs. Fourteen dogs (six in the United Kingdom, eight in Sweden) were clinically examined and skin/hair samples collected for microscopy and histopathology. Blood was collected for haematological, biochemical and endocrine assays. Of 90 dogs surveyed, 39 had current or previous episodes of symmetrical, non-pruritic alopecia and or frizzy coat changes, usually affecting caudal thighs, axillae, dorsum and neck before 18 months of age; 23 dogs had a waxing/waning course. Examined dogs generally matched the pattern described in questionnaires. Hair shaft anomalies comprised occasional distorted anagen bulbs (10 dogs) and transverse fractures (8 dogs). Vertical histopathological sections showed infundibular hyperkeratosis (28 of 30 sections) and low-grade pigment clumping (17 of 30). Subtle telogenisation of hair follicles was unequivocally confirmed by transverse histomorphometric analyses. The follicular dysplasia of curly coated retriever reported here is similar to that of Irish water spaniels and Chesapeake Bay retrievers but distinct from that of Portuguese water dogs. The genetic basis requires further assessment. © 2016 British Small Animal Veterinary Association.

Devices such as diode laser and intense pulsed light (IPL) are in constant development aiming at permanent hair removal, but there are few comparative studies between these technologies. The objective was to comparatively assess axillary hair removal performed by diode laser and IPL and to obtain parameters of referred pain and evolution response for each method. A comparative prospective, double-blind, and randomized study of axillary hair removal performed by the diode laser and IPL was conducted in 21 females. Six sessions were held with application of the diode laser in one axilla and the IPL in the other, with intervals of 30 days and follow-up of 6 months after the last session. Clinical photographs and digital dermoscopy for hair counts in predefined and fixed fields of the treated areas were performed before, 2 weeks after the sixth session, and 6 months after the end of treatment. A questionnaire to assess the pain was applied. The number of hair shafts was significantly reduced with the diode laser and IPL. The diode laser was more effective, although more painful than the IPL. No serious, adverse, or permanent effects were observed with both technologies. Both diode laser and the IPL are effective, safe, and able to produce lasting results in axillary hair removal.

In South Korea, scrub typhus is the most common acute febrile illness in autumn. We analyzed scrub typhus cases reported from 2008 to 2012 to describe the epidemiology of scrub typhus as well as eschar patterns. A total of 30,478 cases were reported from 2008 to 2012; the incidence rates were higher in the southern and western regions of South Korea. The common clinical symptoms of confirmed scrub typhus cases from 2010 to 2012 were fever/chills (95.2%), eschars (78.9%), and myalgia (61.7%). The primary sites of eschars were the lower extremities (19.0%), abdomen/waist (13.4%), and axilla (11.5%) in men and the shoulder/frontal chest (15.1%), lower extremities (14.5%), and abdomen/waist (13.6%) in women. Regardless of gender, eschars tended to be more on the lower extremities among the leisure activities group. Among the occupational farm work group, who usually lived in rural areas, eschars appeared most frequently on the abdomen/waist in men and on the shoulder/frontal chest in women. Eschar patterns were influenced by gender and activities. These results could facilitate the prevention of scrub typhus and clarify the current status of scrub typhus in South Korea.

Full Text Available The skin microbial community is regarded as essential for human health and well-being, but likewise plays an important role in the formation of body odor in, for instance, the axillae. Few molecular-based research was done on the axillary microbiome. This study typified the axillary microbiome of a group of 53 healthy subjects. A profound view was obtained of the interpersonal, intrapersonal and temporal diversity of the human axillary microbiota. Denaturing gradient gel electrophoresis (DGGE and next generation sequencing on 16S rRNA gene region were combined and used as extent to each other. Two important clusters were characterized, where Staphylococcus and Corynebacterium species were the abundant species. Females predominantly clustered within the Staphylococcus cluster (87%, n = 17, whereas males clustered more in the Corynebacterium cluster (39%, n = 36. The axillary microbiota was unique to each individual. Left-right asymmetry occurred in about half of the human population. For the first time, an elaborate study was performed on the dynamics of the axillary microbiome. A relatively stable axillary microbiome was noticed, although a few subjects evolved towards another stable community. The deodorant usage had a proportional linear influence on the species diversity of the axillary microbiome.

patients with micrometastases that might still benefit from an ALND. Efforts should continue to improve the model. As a part of the PhD thesis, new molecular markers were tested for prediction of non-sentinel node metastases. In addition, method of detection of the breast cancer could be a possible predictor of non-sentinel node metastases. It has been hypothesized that breast cancers detected by screening represent a clinical indolent group of cancers with lower risk of non-sentinel node metastases compared to symptomatic cancers. This hypothesis was tested in this thesis in a large Danish dataset. No significant difference in the risk of non-sentinel node metastases was found between patients with screen-detected and symptomatic breast cancers, and a less aggressive treatment of the axilla in patients with screen-detected breast cancers cannot be supported. Likewise, the method of detection is not expected to be able to improve the predictive models. Until 2012, the standard treatment of Danish patients with micrometastases or ITC in the sentinel node was ALND. Still, in selected patients ALND was not performed. This thesis includes a comparison of the risk of axillary recurrence and survival between patients with and without ALND. The overall axillary recurrence rate was only 1.6% after 6 years of follow-up, despite between 9 - 18 % of these patients are expected to have non-sentinel node metastases. No significant difference was seen in axillary recurrence and overall survival between patients with and without ALND. These results support the safety of omitting ALND in patients with only micrometastases or ITC in the sentinel node and since 2012 Danish breast cancer patients with ITC or up to two micrometastatic sentinel nodes are no longer offered an ALND. In Denmark the standard surgical treatment of the axilla in locally recurrent breast cancer is no further treatment of the axilla in case of previous ALND, and ALND in case of previous SLND.  To investigate whether

Ecthyma gangrenosum in a patient with non-Hodgkin lymphoma

Full Text Available Introduction. Ecthyma gangrenosum is a rare disease of the skin that causes the localized necrosis of the skin and subcutaneous fat tissue, leading to the multiple ulcerations surrounded by local hyperaemia. The ulcerations are usually localized in groins, and perianal area. In the majority of cases ecthyma is caused by a Pseudomonas aeruginosa sepsis. The disease usually appears in immunocompromized, most frequently hematological patients. Case report. We presented a 78-year-old woman who had been treated for non-Hodgkin lymphoma for the last 18 years. She had recently been given cytotoxics which led to neutropenia. The patient suddenly developed high fever, chill and diarrhea, followed by ecthyma gangrenosum cutaneous lesions in groins, axillas, right side of the neck and umbilicus. Pseudomonas aeruginosa and Proteus mirabilis, that were sensitive to several antibiotics were isolated. The treatment included rehydratation, antibiotics, surgical debridement and regular dressing with antiseptics. The healing of all lesions was achieved after sixteen weeks of the treatment. Conclusion. If haemorrhagic- necrotic lesions of the skin are developed in immunocompromised, usually haematologic patients, an Ecthyma gangrenosum has to be considered immediately, material for identification of a cause has to be taken, followed by immediate administration of antibiotics effective against Pseudomonas aeruginosa. Surgical debridement and other therapeutic modalities are to be considered in some patients. .

In May 2015, we noticed an increase in carbapenem-resistant Acinetobacter baumannii (CRAB) infections in the Medical Intensive Care Unit (MICU). To investigate this, we studied the extent of environmental contamination and subsequent onward clonal transmission of CRAB. We conducted a one-day point prevalence screening (PPS) of the patients and environment in the MICU. We screened patients using endotracheal tube aspirates and swabs from nares, axillae, groin, rectum, wounds, and exit sites of drains. We collected environmental samples from patients' rooms and environment outside the patients' rooms. CRAB isolates from the PPS and clinical samples over the subsequent one month were studied for genetic relatedness by whole genome sequencing (WGS). We collected 34 samples from seven patients and 244 samples from the environment. On the day of PPS, we identified 8 CRAB carriers: 3 who screened positive and 5 previously known clinical infections. We detected environmental contamination in nearly two-thirds of the rooms housing patients with CRAB. WGS demonstrated genetic clustering of isolates within rooms but not across rooms. We analysed 4 CRAB isolates from clinical samples following the PPS. One genetically-related CRAB was identified in the respiratory sample of a patient with nosocomial pneumonia, who was admitted to the MICU five days after the PPS. The extensive environmental colonization of CRAB by patients highlights the importance of environmental hygiene. The transmission dynamics of CRAB needs further investigation.

Full Text Available Lipoid proteinosis, which is known as “Urbach-Wiethe disease”, was first described in 1929 as “lipoidosis cutis et mucosae” by Urbach and Wiethe. It is a rare autosomal recessive inherited genodermatosis. There are PAS-positive hyaline material deposits in the skin, mucosa and visceral organs. A 23-year-old man, who was suffering from swelling of the lower lip and a fissure on the inner side of the lip, presented to our outpatient clinic. On dermatological examination, there were lower lip edema and infiltration, as well as macroglossia. There were bilateral yellowish papules along his eyelashes. For his ocular findings; it was learned that he had been treated for trichiasis at his childhood. There were multiple atrophic scars on his face, elbows, axilla, knees, and the skin overlying his spinous processes. He had no hoarseness. There was no consanguinity between his mother and father. Physical examination was normal. Three punch biopsies were carried out from his tongue, lips and elbow with the preliminary diagnoses of lipoid proteinosis, Melkersson-Rosenthal syndrome, focal epithelial hyperplasia, amyloidosis, granulomatous cheilitis, atrofoderma, and anetoderma. Deposition of hyaline PAS-positive materials was observed on his histopathological examination. According to the clinical and histopathological findings, the patient was diagnosed as having lipoid proteinosis. Otorhinolaryngologists, ophthalmologists, dermatologists, and neurologists should keep this rare condition in mind in the differential diagnosis.

Diffuse large B-cell lymphoma is the most common type of non-Hodgkin's lymphoma. More than 50% of patients have some site of extra-nodal involvement at diagnosis,including the gastrointestinal tract and bone marrow.However, a diffuse large B-cell lymphoma presenting as acute pancreatitis is rare. A 57-year-old female presented with abdominal pain and matted lymph nodes in her axilla. She was admitted with a diagnosis of acute pancreatitis. Abdominal computed tomography (CT) scan showed diffusely enlarged pancreas due to infiltrative neoplasm and peripancreatic lymphadenopathy. Biopsy of the axillary mass revealed a large B-cell lymphoma.The patient was classified as stage Ⅳ, based on the Ann Arbor Classification, and as having a high-risk lymphoma,based on the International Prognostic Index. She was started on chemotherapy with CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone). Within a week after chemotherapy, the patient's abdominal pain resolved. Follow-up CT scan of the abdomen revealed a marked decrease in the size of the pancreas and peripancreatic lymphadenopathy. A literature search revealed only seven cases of primary involvement of the pancreas in B-cell lymphoma presenting as acute pancreatitis. However, only one case of secondary pancreatic involvement by B-cell lymphoma presenting as acute pancreatitis has been published. Our case appears to be the second report of such a manifestation.Both cases responded well to chemotherapy.

Irradiation (>3Gy) to the breast or axillae before 30years of age increases the risk of secondary breast cancer (SBC). The purpose of this article is to describe the clinical characteristics of SBC and the way of diagnosis in young women (before the age of national screening) in France who had received previous radiotherapy for a childhood or a young adulthood cancer. This retrospective, multicentre study reviewed the medical records of women with SBC before the age of the national screening who had received irradiation (≥3Gy) on part or all of the breast before 30years of age, for any type of tumour except BC. A total of 121 SBC were detected in 104 women with previous radiotherapy. Twenty percent of SBC were detected during regular breast screening and 16% of the women had a regular radiological follow-up. Our results points out that the main proportion of childhood cancer survivors did not benefit from the recommended breast cancer screening. This result is comparable to other previously published studies in other countries. A national screening programme is necessary and should take into account the patient's age, family history, personal medical history and previous radiotherapy to reduce the number of SBC diagnosed at an advanced stage.

Aim: To assess how accurately the sentinel lymph node (SLN) can be identified percutaneously, using gamma probe and ultrasound technology. Materials and methods: Women with breast cancer, scheduled for wide local excision or mastectomy with SLN biopsy (SLNB), were included. Peri-areolar intradermal injection of technetium-99 nanocolloid was performed on the morning of surgery and 1–2 ml of blue dye was injected in the peri-areolar region once the patient was anaesthetized. Prior to surgery, a gamma probe was used over the skin to identify any hot spot that could represent a SLN. Ultrasound, guided by the hot spot, was then used to visualize potential SLNs and guide the insertion of a localizing wire. The accuracy in localizing the SLN by preoperative gamma-probe guided ultrasonography was assessed by comparison to SLNB. Results: A SLN was correctly identified and marked using gamma-probe guided ultrasonography in 44 of 59 cases (75%; 95% CI: 63–86%). Conclusion: This study supports the case for investigating percutaneous gamma probe and ultrasound guided interventions in the axilla in women with breast cancer, as a potential alternative to surgical SLNB. - Highlights: • Percutaneous radio-isotope guided localisation of the SLN was successful in 75% of cases. • Success rates varied slightly by operator. • Success rates did not vary between same-day and previous-day isotope injection methods

A case of lymphoma of T-cell derivation with aberrant expression of three B-cell lineage markers (CD19, CD20, and CD79a), which was diagnosed on a left axillary excision, is described. Immunohistochemical studies and flow cytometry analysis demonstrated neoplastic cells expressing CD3, CD19, CD20, and CD79a with absence of CD4, CD8, CD10, CD30, CD34, CD56, CD68, TDT, MPO, PAX-5, and surface immunoglobulin. Gene rearrangement studies performed on paraffin blocks demonstrated monoclonal T-cell receptor gamma chain rearrangement with no evidence of clonal heavy chain rearrangement. The neoplastic cells were negative for Epstein-Barr virus (EBV) or Human Herpes Virus 8 (HHV-8). At the time of diagnosis, the PET scan demonstrated hypermetabolic neoplastic cells involving the left axilla, bilateral internal jugular areas, mediastinum, right hilum, bilateral lungs, and spleen. However, bone marrow biopsy performed for hemolytic anemia revealed normocellular bone marrow with trilineage maturation. The patient had no evidence of immunodeficiency or infection with EBV or HHV-8. This is the first reported case of a mature T-cell lymphoma with aberrant expression of three B-cell lineage markers. The current report also highlights the need for molecular gene rearrangement studies to determine the precise lineage of ambiguous neoplastic clones. PMID:24066244

It has been well established that axillary phlebography is excellent method in diagnosis of the primary and secondary thrombotic conditions of axillary vein. But the evaluation of veins of axilla is often difficult due to individual variation of veins and to various methods of venography. Axillary phlebographies were made in thirty-three normal Korean adults by modified bolus technique and various measurements and consideration were done for the evaluation of normal anatomical variations. Results were as follows; 1. Axillary vein was visualized satisfactory in 32 cases among 33 cases, basilic vein in 28 cases, and cephalic vein and brachial vein in 15 cases. 2. Bifid basilic vein was observed in 4 cases and trifid basilic vein in 1 case. Anastomosis between cephalic and brachial vein was observed in 5 case. In 1 case, anastomotic site of median cubital vein with basilic vein is more proximal than usual. 3. Average diameter of axillary vein were 9 mm (7-11 mm) in male and 8 mm (5-10 mm) in female at axillary border of scapula and 14 mm (11-18 mm) in male and 13 mm (11-15 mm) in female at midportion of first rib. 4. Streaming and dilution of contrast media, and deformities by valve action were observed in many cases, which may be mistaken as abnormality

Lymphangiomas occurs in children quite frequently. They are most commonly localized in the head, neck, axilla, chest, abdomen, and retroperitoneum. Lymphangiomas of the scrotum are very rare and are usually clinically silent, so they are a challenge for radiologists performing US examination in children. They are obliged to differentiate the following lesions: torsion of the testicle, scrotal hernia, hydrocoele, and epididymal cyst, in addition to the masses of primary extra-testicular localization such as hemagioma, congenital vascular malformations, fibromas, and malignant tumors. Additional difficulties appear in boys who present acute scrotum syndrome. The paper reports the diagnostics and treatment of a huge multicystic lymphangioma situated in he scrotum and retroperitoneum of a 12-year-old boy who had fallen from a bicycle and presented acute scrotum. The lesion of the scrotum was surgically excised. Retroperitoneal lymphangioma was detected during this operation. Subsequent diagnostics was based on ultrasonography, computerized tomography, and magnetic resonance imaging of the abdominal cavity. The lymphangioma of the retroperitoneum was resected. The patient shows no evidence of recurrence after 7 years. Cystic lymphangiomas are rare but benign intra-scrotal, extra-testicular, painless masses in children. They are sonographically multicystic or multiloculated abnormalities and may show infiltrative extension to the perineum, retroperitoneum, or abdomen. Recognition of this entity and its extent is important for correct clinical management and may be for planning treatment. (author)

High concentrations of sub-micron nanoparticles have been shown to be released during laser hair removal (LHR) procedures. These emissions pose a potential biohazard to healthcare workers that have prolonged exposure to LHR plume. We sought to demonstrate that cold sapphire skin cooling done in contact mode might suppress plume dispersion during LHR. A total of 11 patients were recruited for laser hair removal. They were treated on the legs and axilla with a 755 or 1064 nm millisecond-domain laser equipped with either (i) cryogen spray (CSC); (ii) refrigerated air (RA); or (iii) contact cooling with sapphire (CC). Concentration of ultrafine nanoparticles <1 μm were measured just before and during LHR with the three respective cooling methods. For contact cooling (CC), counts remained at baseline levels, below 3,500 parts per cubic centimeter (ppc) for all treatments. In contrast, the CSC system produced large levels of plume, peaking at times to over 400,000 ppc. The CA cooled system produced intermediate levels of plume, about 35,000 ppc (or about 10× baseline). Cold Sapphire Skin cooling with gel suppresses plume during laser hair removal, potentially eliminating the need for smoke evacuators, custom ventilation systems, and respirators during LHR.

Full Text Available Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5, anterior tibia (n=1, posterior axilla (n=1, ischium (n=1, and trochanter (n=2. The template for a bilateral flap was used on the sacrum (n=8, arm (n=1, and anterior tibia (n=1. The causes of the defects were meningocele (n=3, a decubitus ulcer (n=5, pilonidal sinus (n=3, and skin tumor excision (n=10. The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19–80 years. All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

A closed chamber evaporimeter is suitable for measuring transepidermal water loss (TEWL) in cats because of the compact device size, tolerance to sudden movement and short measuring time. TEWL is a representative parameter for skin barrier dysfunction, which is one of the clinical signs of atopic dermatitis in humans and dogs. Measurement of feline TEWL has been reported, but applicability of this parameter has not been validated. The aims of this study were to determine if tape stripping is a valid experimental model in cats for studying TEWL and to determine if a closed chambered system is a suitable measurement tool for cats. Ten clinically normal cats. In order to evaluate variation of the measured values, TEWL was measured at the right and left side of the three clipped regions (axillae, lateral thigh and groin). Subsequently, TEWL was measured using sequential tape stripping of the stratum corneum as a model of acute barrier disruption. The variations between both sides of the three regions showed no significant difference. Sequential tape stripping was associated with increasing values for TEWL. Feline TEWL was shown to reflect changes in the skin barrier in an experimental model using a closed chamber system and has the potential for evaluating skin barrier function in cats with skin diseases. © 2016 ESVD and ACVD.

This was a prospective study to assess positioning-related pain in 20 awake volunteers in the dorsal lithotomy (DL) and lateral decubitus (LD) positions. Each volunteer was put through the series of discrete, sequential steps used to achieve a final position; each step had two options. The Wong-Baker scale (WB) was used to rate pain for each option and the preferred option and ad lib comments were recorded. We found that awake volunteers could clearly and immediately distinguish differences in pain levels between position options. For the DL position, volunteers favored having the arms slightly flexed and pronated as opposed to being straight and supinated reflected by statistically less painful WB scores and option preference. Volunteers preferred having the neck flexed as opposed to being flat. For the LD position, volunteers reported statistically lower pain scores and preference for a foam roll for axilla support as opposed to a rolled blanket, the table flexed without the kidney rest as opposed to a raised kidney rest, and the over arm board as oppose to stacked blankets for contralateral arm support. Ad lib comments from the volunteers supported the above findings. To our knowledge, ours is the first study to demonstrate objective preferences for variations in surgical positioning using awake volunteers. This exercise with awake volunteers resulted in immediate changes in positioning for real robotic surgery patients in our practice.

The brachial plexus is usually formed by the fusion of anterior primary rami of the fifth to eighth cervical and the first thoracic spinal nerves. Variations in the formation of the brachial plexus may occur. Variations in brachial plexus anatomy are important to radiologists, surgeons and anaesthesiologists performing surgical procedures in the neck, axilla and upper limb regions. These variations may lead to deviation from the expected dermatome distribution as well as differences in the motor innervation of muscles of the upper limb. This study is aimed to describe the anatomical variations of brachial plexus in its formation among 20 Ethiopian cadavers. Observational based study was conducted by using 20 cadavers obtained from the Department of Human Anatomy at University of Gondar, Bahir Dar, Addis Ababa, Hawasa, Hayat Medical College and St Paul Hospital Millennium Medical College. Data analysis was conducted using thematic approaches. A total of 20 cadavers examined bilaterally for the formation of brachial plexus. Of the 40 sides, 30 sides (75%) were found normal, seven sides (17.5%) prefixed, three sides (7.5%) postfixed and one side of the cadaver lacks cord formation. The brachial plexus formation in most subjects is found to be normal. Among the variants, the numbers of the prefixed brachial plexuses are greater than the postfixed brachial plexuses. © 2016 Royal Australasian College of Surgeons.

Brachial plexus block is often utilised for proximal arm arteriovenous access creation. However, the medial upper arm and axilla are often inadequately anaesthetised, requiring repeated, intraoperative local anaesthetic supplementation, or conversion into general anaesthesia. We hypothesised that the addition of a PECS II block would improve anaesthesia and analgesia for proximal arm arteriovenous access surgery. In this prospective, double-blinded, randomised proof-of-concept study, 36 consenting adults with end-stage renal disease aged between 21 and 90 years received either a combined supraclavicular and PECS II block (Group PECS, n = 18), or combined supraclavicular and sham block (Group SCB, n = 18) for proximal arm arteriovenous access surgery. Primary outcome was whether patients required intraoperative local anaesthetic supplementation by the surgeon. In Group PECS, 33.3% (6/18) needed local anaesthetic supplementation vs. 100% (18/18) in Group SCB. Group SCB had three times (RR 3.0, 95% CI 1.6-5.8; P PECS required lower volume of supplemental local anaesthetic compared to Group SCB (0.0 ml, IQR 0.0-6.3 ml vs. 15.0 ml, IQR 7.4-17.8 ml; P PECS II block to a supraclavicular block improves regional anaesthesia for patients with end-stage renal disease undergoing proximal arm arteriovenous access surgery. © 2018 The Acta Anaesthesiologica Scandinavica Foundation.

Mammary implants marketed by Poly Implant Prothèse (PIP) were found to contain industrial grade silicone and this caused heightened anxiety and extensive publicity regarding their safety in humans. These implants were used in a large number of patients worldwide for augmentation or breast reconstruction. We reviewed articles identified by searches of Medline, PubMed, Embase, and Google Scholar databases up to May 2014 using the terms: "PIP", "Poly Implant Prothèse", "breast implants" and "augmentation mammoplasty" "siloxanes" or "silicone". In addition the websites of regulating bodies in Europe, USA, and Australia were searched for reports related to PIP mammary implants. PIP mammary implants are more likely to rupture than other implants and can cause adverse effects in the short to the medium term related to the symptoms of rupture such as pain, lumps in the breast and axilla and anxiety. Based on peer-reviewed published studies we have calculated an overall rupture rate of 14.5% (383/2,635) for PIP implants. However, there is no evidence that PIP implant rupture causes long-term adverse health effects in humans so far. Silicone lymphadenopathy represents a foreign body reaction and should be treated conservatively. The long-term adverse effects usually arise from inappropriate extensive surgery, such as axillary lymph node dissection or extensive resection of breast tissue due to silicone leakage.

To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb) and deoxyhemoglobin (DeoxyHb) levels were detected before and after treatment after 15, 30, and 45 days. In this cohort, pretreatment OxyHb (mean ± SD) is 1.32 ± 0.14 (medium-high), and DeoxyHb is 0.87 ± 0.13 (normal). All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23 ± 0.09 (normal-medium, 15-day), 1.16 ± 0.08 (normal, 30-day), and 1.05 ± 0.04 (normal, 45-day), and DeoxyHb levels are 0.90 ± 0.11 (normal, 15-day), 0.94 ± 0.18 (normal, 30-day), and 0.98 ± 0.12 (normal, 45-day). Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

The purpose of this study was to evaluate the radiotherapeutic management of 38 patients, with malignant lymphoma of the thyroid, seen at the Mayo Clinic between 1965 and 1979. There were 8 males and 30 females with ages ranging from 34 to 90 years. A tissue diagnosis was made in all patients and tissue was available for reclassification under the Working Formulation in 31 of the 38 patients. Twenty-six patients had intermediate grade histology, four low grade and one indeterminate. All patients were treated with approximately 4000 rad megavoltage irradiation (range 2400-6000 rad) to the neck only (10 patients) or neck and mediastinum (28 patients). Twenty patients received subdiaphragmatic radiotherapy and four patients received adjuvant chemotherapy. Patients receiving radiation treatment to the neck and mediastinum and those with no gross residual disease at the initation of radiotherapy were less likely to develop a recurrence. Patients receiving a planned break during the course of therapy did not have reduced overall disease-free survival. Only 1 of 4 patients (25%) receiving adjuvant chemotherapy survived one year. Side effects of radiotherapy were minimal. The authors believe the radiotherapeutic management of clinical Stage IE and IIE primary thyroid lymphoma should include treatment of the neck, axillae and mediastinum to a dose of approximately 4000 rad using a continuous course technique. Additionally, gross total removal of the disease surgically may be beneficial

To intra-individually compare the diagnostic image quality of Dixon and spectral fat suppression at 3 T. Fifty consecutive patients (mean age 55.1 years) undergoing 3 T breast MRI were recruited for this prospective study. The image protocol included pre-contrast and delayed post-contrast spectral and Dixon fat-suppressed T1w series. Two independent blinded readers compared spectral and Dixon fat-suppressed series by evaluating six ordinal (1 worst to 5 best) image quality criteria (image quality, delineation of anatomical structures, fat suppression in the breast and axilla, lesion delineation and internal enhancement). Breast density and size were assessed. Data analysis included Spearman's rank correlation coefficient and visual grading characteristics (VGC) analysis. Four examinations were excluded; 48 examinations in 46 patients were evaluated. In VGC analysis, the Dixon technique was superior regarding image quality criteria analysed (P < 0.01). Smaller breast size and lower breast density were significantly (P < 0.01) correlated with impaired spectral fat suppression quality. No such correlation was identified for the Dixon technique, which showed reconstruction-based water-fat mixups leading to insufficient image quality in 20.8 %. The Dixon technique outperformed spectral fat suppression in all evaluated criteria (P < 0.01). Non-diagnostic examinations can be avoided by fat and water image reconstruction. The superior image quality of the Dixon technique can improve breast MRI interpretation. (orig.)

Hydroxyisohexyl-3-cyclohexene carboxaldehyde (HICC) known as Lyral is a frequent allergen. It is used in more than 50% of marketed deodorants. The aim of the present study was to determine elicitation thresholds for HICC under simulated conditions of deodorant use. 15 patients with previously diagnosed contact allergy to HICC were patch tested with 5 solutions of HICC-scented and HICC-unscented deodorants. Patients and 10 healthy controls performed a use test in the axillae using deodorants scented with HICC in increasing concentrations and unscented deodorants as control. The concentration of HICC was increased every second week (200, 600, and 1800 p.p.m.) until either a reaction developed or for 6 weeks. 14 patients completed the study, and all developed unilateral eczema from the HICC-containing deodorant, while controls were all negative (P= 0.004). In 9/14 patients, a positive use test developed during the first 2 weeks to the deodorant containing 200 p.p.m. HICC. Positive correlations were found between the day of positive use and patch test threshold concentration of the HICC solutions (r= 0.71, P= 0.01) as well as the patch test thresholds of the HICC-scented deodorants (r= 0.74, P= 0.007). In conclusion, HICC elicits allergic contact dermatitis in a high proportion of sensitized individuals at common usage concentrations in deodorants.

One hundred and one consecutive patients with newly diagnosed stage I Hodgkin's disease (HD) received treatment at St Bartholomew's Hospital, between 1968 and 1987, with a median follow-up of 12 years. Actuarial analysis predicts 78% to be alive and without relapse of Hodgkin's disease at 15 years. Ninety evaluable patients received either mantle or inverted 'Y' radiotherapy. Histology at presentation was nodular sclerosing (39), lymphocytic predominant (27) or mixed cellularity (24). The presenting site was neck (78), axilla (6) groin (4) and mediastinum (2). Complete remission was achieved in all evaluable patients, the actuarial proportion in remission being 75% at 15 years. Factors predictive of a prolonged remission were pathological staging versus clinical staging and lymph node size < 3 cm. Actuarial overall survival in these 90 patients was 75% at 15 years. Relapse of HD has occurred in 18 patients. Second remission was achieved in 15/18. The actuarial rate of second remission and survival was 40% at 10 years. Sixteen patients have died, 7 of Hodgkin's disease, 7 of unrelated causes and 2 of second malignancy. A further 3 patients who developed second malignancy are still alive. At 15 years the actuarial mortality related to HD was 12%. These results confirm the importance of long follow up to assess the efficacy of primary therapy. (author)

Background: Sentinel Lymph Node Biopsy [SLNB) procedure was found to be an accurate method of staging the axilla in patients with early stage breast cancer. The standard of care for breast cancer patients with positive SLN metastasis includes complete Axillary Lymph Node Dissection (ALND). Haw ever, in 40-70% of patients, the SLN the only involved axillary node. Factors predicting non SLW metastasis should be identified in order to define subgroups of patient with positive SLN in whom the axilla may be staged by SLNB done. Objective: To identify the factors predicting metastatic involvement of the non-SLNs in breast cancer patients having SLN metastases. Patients and Methods: Data were collected and analyzed from 80 patients with early stage invasive breast cancer (T1, T2, N0, M0) who underwent SLNB at the surgical Oncology Department, Kuwait Cancel control Center (KCCC) between November 2004 and February 2009. SLNB was perfomed using a combined technique (radioactive colloid, and blue dye) in the majority of cases in some cases, only one technique was used. Complete ALND was performed in the case of failure of SLN identification and in patients with positive SLN. Multiple variables (patient, tumor and of SLN identification and in patients with positive SLN. Multiple variables (patient, tumor, and SLN characteristics) with tested as possible predictors of non sentinel lymph node metastasis. Results: The mean age of patients at diagnosis was 46.6 years. The median tumor size was 2 cm. The SLN identification rate was 96.2% (77 out of 80 patients). The SLN was positive in 24 patients(31%), and half of these showed evidence of capsular invasion. The median number of SLNs removed was two. The median number positive SLNs was one. The incidence of non-SLN metatasis associated with positive SLN was 50% (12 out of 24 patients). lymphovascular invasion was found to be the only factor associated with non-SLN metastases. In addition, two trends were observed, though they did

As there are multiple lymphatic pathways from the breast to the axilla with multiple possible choices for a cancer cell or a colloid, it appears intuitively unusual that one node is preferentially 'chosen'. The intuitive response would be that there is an equal chance for a breast cancer cell to travel by any lymphatic pathway to any axillary node at level 1. If this were true, then after a colloid injection into the peritumoural lymphatics or the periareolar lymphatic plexus, such a colloid has a similar chance to travel to any level 1 axillary node, be it an involved node or an uninvolved node. We have tried to resolve this conflict between intuition and practice. It was tested by identifying and measuring the activity of the radiolabelled colloid in the nodes removed in an axillary clearance and in the sentinel node or nodes after applying a sentinel node technique similar to that of Veronesi et al. The histology of all the nodes that were counted was analysed so that the colloid activity in each node was able to be correlated with its histology, whether it was involved with cancer or not involved. Measurements were obtained in those patients, in whom there were both involved and uninvolved nodes in the axillae. The colloid counts in cpm/g of each node were compared with the related sentinel node findings either involved with cancer or not involved. These were calculated either as the involved to uninvolved that is a 'positive' to 'negative' ratio. The results were that the activity ratio of all involved axillary nodes to uninvolved axillary nodes was about 4:1. The involved Sentinel nodes had on average over 25 times the uptake of the uninvolved Sentinel nodes. P value was <0.009 for a significant difference between colloid uptake in sentinel nodes with positive histology and those with negative histology. It is a new observation that involved axillary nodes show greater uptake of the colloid than uninvolved nodes in all patients where there are both involved

Full Text Available Introduction & Objective: The breast cancer is the most common malignancy in women and in recent years it is seen in younger ages. Because of dense breast tissue in these ages, the mammography sensitivity for breast cancer detection is reduced, so high quality ultrasonography (US as a combined screening method is effective. The aim of this study is the evaluation of the mammographic finding with the positive finding of ultrasonogarphy.Materials & Methods: In this cross-sectional study 300 cases were referred to the Mehr Medical Imaging Center for breast US and sonography of breast and axilla was performed. Mammography before or after US was also performed by another radiologist. All suspicious patients were referred for biopsy or surgery.Results: Mean age of patients was 46 y/o with the range of 32-76 y/o. Pathologic specimens approved malignancy in 21 patients and abscess in 1 patient. The most frequent symptom was palpable breast mass with mean diameter of 29 mm. Mean diameter of lymph nodes was 17.3 mm. Positive mammographic findings were seen in 85.7%and negative findings or only an asymmetric density in 14.3%.Conclusion: According to dense breast tissue especially in young women sensitivity of single screening by mammography is reduced in breast cancer detection, so combined screening with sonography and mammography especially in younger women improves the detection rate of breast carcinoma.

Summary Latissimus dorsi transfer is our preferred treatment for active disabled patients with a posterosuperior massive cuff tear. We present an arthroscopically assisted technique which avoids an incision through the deltoid obtaining a better and faster clinical outcome. The patient is placed in lateral decubitus. After the arthroscopic evaluation of the lesion through a posterior and a posterolateral portal, with the limb in traction we perform the preparation of the greater tuberosity of the humerus. We place the arm in abduction and internal rotation and we proceed to the harvest of the latissimus dorsi and the tendon preparation by stitching the two sides using very resistant sutures. After restoring limb traction, under arthroscopic visualization, we pass a curved grasper through the posterolateral portal by going to the armpit in the space between the teres minor and the posterior deltoid. Once the grasper has exited the access at the level of the axilla we fix two drainage transparent tubes, each with a wire inside, and, withdrawing it back, we shuttle the two tubes in the subacromial space. After tensioning the suture wires from the anterior portals these are assembled in a knotless anchor of 5.5 mm that we place in the prepared site on the greater tuberosity of the humerus. A shoulder brace at 15° of abduction and neutral rotation protect the patient for the first month post-surgery but physical therapy can immediately start. PMID:23738290

Full text: Axillary lymph node status is an essential element in the staging of breast cancer. Recently, lymphatic mapping and sentinel node (SN) identification with lymphoscintigraphy has been promoted. The purposes of this study were to determine: (1) factors important in optimal identification of SNs preoperatively and (2) accuracy of SNs in predicting axillary lymph node status. Lymphoscintigraphy using 99 Tc m -antimony trisulphide colloid was performed in 35 patients before axillary dissection surgery. Four injections (20 MBq in 0.5 ml) were administered either around the biopsy cavity/scar or peritumorally. Sequential images in the anterior, anterior oblique and lateral projections were obtained until a SN was identified and in some patients delayed images (up to 15 h) were required. SNs were marked on the patient's skin in two planes. During surgery, a hand-held gamma probe was used to localize the marked SNs, which were removed prior to complete axillary dissection. Dissected lymph nodes were evaluated histopathologically for tumour involvement. To optimize SN identification, we found that breast cleaning post-injection, breast massage, imaging with arms both raised and lowered, and using different symbols to mark multiple SNs were necessary. In 32/35 patients (91%), a SN was successfully identified. Drainage patterns varied and were primarily to the axilla, internal mammary chain and intra clavicular areas. The SN appears to be an accurate predictor of axillary node status. In conclusion, breast lymphoscintigraphy is a simple procedure which appears to accurately identify sentinel nodes

Chemosignals of stress influence social judgments.

Full Text Available Human body odors have important communicative functions regarding genetic identity, immune fitness and general health, but an expanding body of research suggests they can also communicate information about an individual's emotional state. In the current study, we tested whether axillary odors obtained from women experiencing psychosocial stress could negatively influence personality judgments of warmth and competence made about other women depicted in video scenarios. 44 female donors provided three types of sweat samples: untreated exercise sweat, untreated stress sweat and treated stress sweat. After a 'washout' period, a commercial unscented anti-perspirant product was applied to the left axilla only to evaluate whether 'blocking' the stress signal would improve the social evaluations. A separate group of male and female evaluators (n = 120 rated the women in the videos while smelling one of the three types of sweat samples. Women in the video scenes were rated as being more stressed by both men and women when smelling the untreated vs. treated stress sweat. For men only, the women in the videos were rated as less confident, trustworthy and competent when smelling both the untreated stress and exercise sweat in contrast to the treated stress sweat. Women's social judgments were unaffected by sniffing the pads. The results have implications for influencing multiple types of professional and personal social interactions and impression management and extend our understanding of the social communicative function of body odors.

The current management of the axilla in level 1 node-positive breast cancer patients is axillary lymph node dissection regardless of the status of the level 2 axillary lymph nodes. The goal of this study was to develop a nomogram predicting the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in patients with level 1 axillary node-positive breast cancer. We reviewed the records of 974 patients with pathology-confirmed level 1 node-positive breast cancer between 2010 and 2014 at the Liaoning Cancer Hospital and Institute. The patients were randomized 1:1 and divided into a modeling group and a validation group. Clinical and pathological features of the patients were assessed with uni- and multivariate logistic regression. A nomogram based on independent predictors for the L-2-ALNM identified by multivariate logistic regression was constructed. Independent predictors of L-2-ALNM by the multivariate logistic regression analysis included tumor size, Ki-67 status, histological grade, and number of positive level 1 axillary lymph nodes. The areas under the receiver operating characteristic curve of the modeling set and the validation set were 0.828 and 0.816, respectively. The false-negative rates of the L-2-ALNM nomogram were 1.82% and 7.41% for the predicted probability cut-off points of level 1 axillary lymph node metastasis. Patients with a low probability of L-2-ALNM could be spared level 2 axillary lymph node dissection, thereby reducing postoperative morbidity.

The goal is to fully automate the calculation of a breast ptosis measure from clinical photographs through automatic localization of fiducial points relevant to the measure. Sixty-eight women (97 clinical photographs) who underwent or were scheduled for breast reconstruction were included. The photographs were divided into a development set (N = 49) and an evaluation set (N = 48). The breast ptosis measure is obtained automatically from distances between three fiducial points: the nipple, the lowest visible point of breast (LVP), and the lateral terminus of the inframammary fold (LT). The nipple is localized using the YIQ colour space to highlight the contrast between the areola and the surrounding breast skin. The areola is localized using its shape, location and high Q component intensity. The breast contour is estimated using Dijkstra's shortest path algorithm on the gradient of the photograph in greyscale. The lowest point of the estimated contour is set as the LVP. To locate the anatomically subtle LT, the location of patient's axilla is used as a reference. The algorithm's efficacy was evaluated by comparing manual and automated localizations of the fiducial points. The average nipple diameter was used as a cut-off to define success. The algorithm showed 90, 91 and 83% accuracy for locating the nipple, LVP and LT in the evaluation set, respectively. This study presents a new automated algorithm that may facilitate the quantification of breast ptosis from lateral views of patients' photographs. © 2015 John Wiley & Sons, Ltd.

to determine the rate of MRSA-carrier among patients, family members and health care providers, and the association between MRSA-carrier family members and health care providers on MRSA infection patient after orthopaedic surgery. this is a cross-sectional analytical study. Samples were taken consecutively during December 2010 to December 2011, consisting of postoperative patients infected with MRSA, attending family members, and the medical officers with history of contact with the patient. Swab culture were taken from nasal and axilla of all subjects. The incidence of MRSA infection, and MRSA-carrier on the patient, family members and medical officers were presented descriptively, while their association with MRSA infection was statistically tested using Fischer exact test. during the study period, there were 759 surgeries, with 4 (0.5%) patients were identified to have MRSA infection. Of these four cases, 48 subjects were enrolled. The rate of MRSA-carrier among patients, family and health care providers were 50%, 25% and 0% respectively. There were no significant association between MRSA and the rates of MRSA-carrier on the family member or health care providers. the incidence of MRSA infection, MRSA-carrier patient, MRSA-carrier health care providers, and family member carrier were 0.5%, 50%, 0%, and 25% respectively. No significant association found between MRSA-carrier on the family member or health care providers and MRSA infection patient. There were no MRSA infection found on the health care provider.

Clear-PEM is a dedicated PET scanner for breast and axilla cancer diagnosis, under development within the framework of the Crystal Clear Collaboration at CERN, aiming at the detection of tumors down to 2 mm in diameter. The camera consists of two planar detector heads with active dimensions 16.0x14.5 cm 2 . Each head has 96 Clear-PEM detector modules consisting of 32 LYSO:Ce pixels with dimensions 2x2x20 mm 3 packed in a 4x8 BaSO 4 reflector matrix compressed between two Hamamatsu S8550 APD arrays in a double-readout configuration for Depth-of-Interaction (DoI) determination. The modules are individually measured and characterized before being grouped into Supermodules (comprised of 24 modules). Measured properties include photo-peak position, relative gain dispersion, energy resolution, cross-talk and DoI resolution. Optical inspection of matrices was also performed with the aid of a microscope, to search for pixel misalignments and matrix defects. Modules' performance was thoroughly evaluated with a 511 keV collimated beam to exactly determine DoI resolution. In addition, a fast quality control (QC) procedure using flood irradiations from a 137 Cs source was applied systematically. The overall performance of the 24 detector modules complies with the design goals of the Clear-PEM detector, showing energy resolution around 15%, DoI resolution of about 2 mm and gain dispersion among pixels of 15%

Clonidine is effective for the treatment of primary idiopathic hyperhidrosis and hot flushes: a case report.

While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back. His complaint was associated with a transient hot sensation and erythema over the affected areas. He did not respond to topical antiperspirants containing aluminum chloride, topical aluminum chloride, or to botulinum toxin A injected in both inguinal areas. He was then referred to an endocrinology clinic to rule out secondary causes of hyperhidrosis and hot flushes; a primary diagnosis was confirmed. He did not respond to oral glycopyrrolate and additionally was complaining of its anticholinergic side effects. The glycopyrrolate was then replaced with oral clonidine 0.15 mg twice a day. Clonidine was well tolerated without remarkable side effects and he quickly started to feel marked improvement which was maintained for 2 years. I report an atypical presentation of primary hyperhidrosis and hot flushes that was effectively controlled by clonidine without remarkable side effects. Further research on a large number of patients may be required before recommending clonidine in similar conditions.

Shampoo therapy is often recommended for the control of Malassezia overgrowth in dogs. The aim of this study was to evaluate the in vivo activity of a 2% climbazole shampoo against Malassezia pachydermatis yeasts in naturally infected dogs. Eleven research colony Beagles were used. The dogs were distributed randomly into two groups: group A (n=6) and group B (n=5). Group A dogs were washed with a 2% climbazole shampoo, while group B dogs were treated with a physiological shampoo base. The shampoos were applied once weekly for two weeks. The population size of Malassezia yeasts on skin was determined by fungal culture through modified Dixon's medium contact plates pressed on left concave pinna, axillae, groins, perianal area before and after shampoo application. Samples collected were compared by Wilcoxon rank sum test. Samples collected after 2% climbazole shampoo application showed a significant and rapid reduction of Malassezia population sizes. One hour after the first climbazole shampoo application, Malassezia reduction was already statistically significant and 15 days after the second climbazole shampoo, Malassezia population sizes were still significantly decreased. No significant reduction of Malassezia population sizes was observed in group B dogs. The application of a 2% climbazole shampoo significantly reduced Malassezia population sizes on the skin of naturally infected dogs. Application of 2% climbazole shampoo may be useful for the control of Malassezia overgrowth and it may be also proposed as prevention when recurrences are frequent.

Breast cancer is the most common female malignancy worldwide. Pakistan has the highest incidence rate of breast cancer than any other Asian population. The purpose of the study was to evaluate the worth of sono-mammography in diagnosis of symptomatic breast diseases by comparing it with mammogram. Methods: In this cross-sectional validation study, 45 subjects with mean age of 45+-12.07 were included. Majority of the patients presented with complaint of breast lump. After complete history and clinical examination, all the patients had high resolution ultrasound of bilateral breasts and axilla followed by bilateral mammography. Histopathology was taken as gold standard in this study. The exclusion criteria were pregnancy and patients having direct clinical signs of breast malignancy. Results: Based on histopathology, out of 45 patients with breast symptoms, 12 patients had benign lesions, whereas 32 patients were diagnosed as the cases of breast cancers. Finally one patient did not have biopsy proven final diagnosis. Sensitivity and specificity of ultrasound were calculated to be 100% and 67% as compared to sensitivity and specificity of 90.6% and 91.7% for that of mammography. Conclusions: Ultrasound is a useful complementary tool to mammography in assessment of symptomatic breast diseases since it helps in characterization and localization of breast lesions seen on mammogram and it is not limited by dense breasts. Also it should be the considered as initial imaging technique for assessment of palpable breast lumps. (author)

Despite considerable progress in identifying causal genes for lipodystrophy syndromes, the molecular basis of some peculiar adipose tissue disorders remains obscure. In an Israeli-Arab pedigree with a novel autosomal recessive, multiple symmetric lipomatosis (MSL), partial lipodystrophy and myopathy, we conducted exome sequencing of two affected siblings to identify the disease-causing mutation. The 41-year-old female proband and her 36-year-old brother reported marked accumulation of subcutaneous fat in the face, neck, axillae, and trunk but loss of subcutaneous fat from the lower extremities and progressive distal symmetric myopathy during adulthood. They had increased serum creatine kinase levels, hypertriglyceridemia and low levels of high-density lipoprotein cholesterol. Exome sequencing identified a novel homozygous NC_000019.9:g.42906092C>A variant on chromosome 19, leading to a NM_005357.3:c.3103G>T nucleotide change in coding DNA and corresponding p.(Glu1035*) protein change in hormone sensitive lipase (LIPE) gene as the disease-causing variant. Sanger sequencing further confirmed the segregation of the mutation in the family. Hormone sensitive lipase is the predominant regulator of lipolysis from adipocytes, releasing free fatty acids from stored triglycerides. The homozygous null LIPE mutation could result in marked inhibition of lipolysis from some adipose tissue depots and thus may induce an extremely rare phenotype of MSL and partial lipodystrophy in adulthood associated with complications of insulin resistance, such as diabetes, hypertriglyceridemia and hepatic steatosis. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

We evaluated the concordance between peri-areolar blue dye and peri-incisional radiotracer injections for axillary sentinel node mapping of patients with the history of previous breast lesion excisional biopsy. 80 patients with the history of previous excisional biopsy of the breast lesions were included. All patients received two injections of 99mTc-antimony sulfide colloid in both ends of incision line in an intradermal fashion. 2 mL patient blue V dye was injection to all patients in the peri-areolar area of the index quadrant after induction of anesthesia. All blue or hot nodes were harvested as sentinel lymph nodes. At least one sentinel node could be detected during surgery in 79 patients. In total 94 sentinel nodes were detected. All detected sentinel nodes were hot. In three patients sentinel nodes were detected by gamma probe but not blue dye. The tumor location in all of these patients was in the upper lateral quadrant and the incision line was extended into the axillary tail of the breast in all of them. 91 out of 94 sentinel nodes were stained blue, which amounts to 95.8% concordance between blue dye and radiotracer on a per node analysis. Single peri-areolar injection in the index quadrant would suffice for sentinel node mapping of patients with history of excisional biopsy. Care should be taken in patients with large excisional biopsy in the extreme proximity to axilla.

Highlights: •Quantitative image analysis showed promise in evaluating axillary lymph nodes. •13 of 28 features performed better than guessing at metastatic status. •When all features were used in together, a considerably higher AUC was obtained. -- Abstract: Purpose: To assess the performance of computer extracted feature analysis of dynamic contrast enhanced (DCE) magnetic resonance images (MRI) of axillary lymph nodes. To determine which quantitative features best predict nodal metastasis. Methods: This institutional board-approved HIPAA compliant study, in which informed patient consent was waived, collected enhanced T1 images of the axilla from patients with breast cancer. Lesion segmentation and feature analysis were performed on 192 nodes using a laboratory-developed quantitative image analysis (QIA) workstation. The importance of 28 features were assessed. Classification used the features as input to a neural net classifier in a leave-one-case-out cross-validation and evaluated with receiver operating characteristic (ROC) analysis. Results: The area under the ROC curve (AUC) values for features in the task of distinguishing between positive and negative nodes ranged from just over 0.50 to 0.70. Five features yielded AUCs greater than 0.65: two morphological and three textural features. In cross-validation, the neural net classifier obtained an AUC of 0.88 (SE 0.03) for the task of distinguishing between positive and negative nodes. Conclusion: QIA of DCE MRI demonstrated promising performance in discriminating between positive and negative axillary nodes.

Assessment of leakage dose in vivo in patients undergoing radiotherapy for breast cancer

2018-01-01

Full Text Available Background and purpose: Accurate quantification of the relatively small radiation doses delivered to untargeted regions during breast irradiation in patients with breast cancer is of increasing clinical interest for the purpose of estimating long-term radiation-related risks. Out-of-field dose calculations from commercial planning systems however may be inaccurate which can impact estimates for long-term risks associated with treatment. This work compares calculated and measured dose out-of-field and explores the application of a correction for leakage radiation. Materials and methods: Dose calculations of a Boltzmann transport equation solver, pencil beam-type, and superposition-type algorithms from a commercial treatment planning system (TPS were compared with in vivo thermoluminescent dosimetry (TLD measurements conducted out-of-field on the contralateral chest at points corresponding to the thyroid, axilla and contralateral breast of eleven patients undergoing tangential beam radiotherapy for breast cancer. Results: Overall, the TPS was found to under-estimate doses at points distal to the radiation field edge with a modern linear Boltzmann transport equation solver providing the best estimates. Application of an additive correction for leakage (0.04% of central axis dose improved correlation between the measured and calculated doses at points greater than 15 cm from the field edge. Conclusions: Application of a correction for leakage doses within peripheral regions is feasible and could improve accuracy of TPS in estimating out-of-field doses in breast radiotherapy.

Protecting the radiation-damaged skin from friction: a mini review

International Nuclear Information System (INIS)

Herst, Patries M

2014-01-01

Radiation-induced skin reactions are an unavoidable side effect of external beam radiation therapy, particularly in areas prone to friction and excess moisture such as the axilla, head and neck region, perineum and skin folds. Clinical studies investigating interventions for preventing or managing these reactions have largely focussed on formulations with moisturising, anti-inflammatory, anti-microbial and wound healing properties. However, none of these interventions has emerged as a consistent candidate for best practice. Much less emphasis has been placed on evaluating ways to protect the radiation-damaged skin from friction and excess moisture. This mini review analyses the clinical evidence for barrier products that form a protective layer by adhering very closely to the skin folds and do not cause further trauma to the radiation-damaged skin upon removal. A database search identified only two types of barrier products that fitted these criteria and these were tested in two case series and six controlled clinical trials. Friction protection was most effective when the interventions were used from the start of treatment and continued for several weeks after completion of treatment. Soft silicone dressings (Mepilex Lite and Mepitel Film) and Cavilon No Sting Barrier Film, but not Cavilon Moisturizing Barrier Cream, decreased skin reaction severity, most likely due to differences in formulation and skin build-up properties. It seems that prophylactic use of friction protection of areas at risk could be a worthwhile addition to routine care of radiation-damaged skin

Full Text Available Purpose. To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. Methods. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb and deoxyhemoglobin (DeoxyHb levels were detected before and after treatment after 15, 30, and 45 days. Results. In this cohort, pretreatment OxyHb (mean ± SD is 1.32±0.14 (medium-high, and DeoxyHb is 0.87±0.13 (normal. All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23±0.09 (normal-medium, 15-day, 1.16±0.08 (normal, 30-day, and 1.05±0.04 (normal, 45-day, and DeoxyHb levels are 0.90±0.11 (normal, 15-day, 0.94±0.18 (normal, 30-day, and 0.98±0.12 (normal, 45-day. Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Conclusion. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

Lyral is a fragrance that is present in many cosmetic products. It has turned into an emergent allergen during the last years. In studies carried out in other European countries, the prevalence of sensitization to Lyral has been found to be 1.9-2.7 %, but it is unknown the prevalence in Spain, as well as the need to include it or not in the standard series of the Spanish Group of Contact Dermatitis (GEIDC). We have patch-tested to Lyral all patients with suspicion of contact dermatitis of any origin who attended our Service between April and May-2005. From a total of 170 patients included in our study, 2 of them had a sensitization to Lyral (1.2 %). One of these two patients had an axillae contact dermatitis caused by a deodorant containing Lyral. The other patient was a masseur-woman with a contact dermatitis on both hands, with periods of dissemination to upper extremities and trunk, and who used several cosmetics products for private reasons and during her job. Although the sample of this study is quite small, we think that the results allow to suspect that Lyral is one of the main allergens, or even the most important, in causing allergic contact dermatitis to fragrances in our environment. Therefore, we believe that we must raise the inclusion of Lyral in the standard series of GEIDC, either as independent allergen, or including it in a new mixture of fragrances.

The concept of sentinel lymph node biopsy in breast cancer surgery is based on the fact that the tumour drains in a logical way via the lymphatic system, from the first to upper levels. Since axillary node dissection does not improve the prognosis of patients with breast cancer, sentinel lymph node biopsy might replace complete axillary dissection for staging of the axilla in clinically N0 patients. Sentinel lymph node biopsy would represent a significant advantage as a minimally invasive procedure, considering that about 70% of patients are found to be free from metastatic disease, yet axillary node dissection can lead to significant morbidity. Subdermal or peritumoural injection of small aliquots (and very low activity) of radiotracer is preferred to intratumoural administration, and (99m)Tc-labelled colloids with most of the particles in the 100-200 nm size range would be ideal for radioguided sentinel node biopsy in breast cancer. The success rate of radioguidance in localising the sentinel lymph node in breast cancer surgery is about 97% in institutions where a high number of procedures are performed, and the success rate of lymphoscintigraphy in sentinel node detection is about 100%. The sentinel lymph node should be processed for intraoperative frozen section examination in its entirety, based on conventional histopathology and, when necessary, immune staining with anti-cytokeratin antibody. Nowadays, lymphoscintigraphy is a useful procedure in patients with different clinical evidence of breast cancer.

In this paper, we present a soft wearable robot for the shoulder which has the potential to assist individuals suffering from a range of neuromuscular conditions affecting the shoulder to perform activities of daily living. This wearable robot combines two types of soft textile pneumatic actuators which were custom developed for this particular application to support the upper arm through shoulder abduction and horizontal flexion/extension. The advantage of a textile-based approach is that the robot can be lightweight, low-profile, comfortable and non-restrictive to the wearer, and easy to don like an item of clothing. The actuator's ability to fold flat when not in use allows the robot to be almost invisible under clothing, potentially allowing the user to avoid any stigma associated with using assistive devices in public. To abduct the arm, a textilebased pneumatic actuator was developed to fit within the axilla to push the arm upwards, while a pair of smaller actuators pivot the abduction actuator to allow for horizontal extension and flexion. The individual textile actuators were experimentally evaluated before being integrated into a wearable garment. Human subject testing was performed to evaluate the ability of the robot to assist the arm by monitoring changes in biological muscle activity when comparing the robot powered on and off. Preliminary results show large reductions in muscular effort in targeted muscles, demonstrating the feasibility and promise of such a soft wearable robot for the shoulder.

During ultrasound-guided cannulation, venous filling is required for venipuncture. Tourniquet with an elastic tube at the axilla is the most common method to induce venous stasis for cannulation of the deep veins of the arm. Although effective, this method might be associated with short- and long-term complications. Valsalva manoeuvre has been used to produce venous filling in other extrathoracic veins. The aim of this observational study is to demonstrate the effect of Valsalva manoeuvre in respect of the elastic tourniquet on venous distention during echography-guided cannulation of the deep veins of the arm. Sixty-nine patients scheduled for cannulation of basilic or brachial vein were prospectively observed. Vein diameters were recorded at rest and after 10 s of Valsalva or tourniquet placement. The mean difference between basilic vein diameters during tourniquet and Valsalva manoeuvre was 0.006 mm (95% confidence interval = -inf, 0.09) with a standard deviation of 0.5 mm (95% confidence interval = 0.5, 0.7; p > 0.01). The mean difference between brachial vein diameters during tourniquet and Valsalva manoeuvre was 0.04 mm (95% confidence interval = -0.23, 0.15) with a standard deviation of 0.8 mm (95% confidence interval = 0.7, 0.9; p > 0.01). This increase in cross-sectional basilic and brachial vein diameters was not different to that obtained with the elastic tube tourniquet.

A 44-year-old man was referred for a right chest nodule of 3 months duration. A 'benign' nodule had been excised from this location 8 years prior. On examination, palpable nodes were noted in the right axilla. Radiographic studies were significant only for right axillary lymphadenopathy. Histologically, a nodular dermal proliferation composed of poorly differentiated epithelioid cells in nests and focally forming ducts with pseudopapillary architecture comprised the primary tumor. Features of a clear cell hidradenoma were noted focally. Immunohistochemical (IHC) analysis revealed reactivity for HMW cytokeratins, CK5 and CK7, p53, p63, CEA (focal), androgen receptor, EGFR, estrogen receptor (ER), MUC5AC, and strong/diffuse membranous staining for Her-2/neu. Negative stains included villin, TTF-1, CDX2, S-100 protein, vimentin, gross cystic disease fluid protein 15 (GCDFP-15), mammoglobulin, and MUC2. A wide local excision and axillary node dissection was performed. Metastatic tumor involved nine of 28 nodes. Interphase fluorescence in situ hybridization (FISH) demonstrated chromosomal amplification of the Her-2/neu locus within the tumor and a nodal metastasis. The patient has completed adjuvant and radiotherapy, including trastuzumab, and is asymptomatic. We believe this to be the first demonstration of Her-2/neu amplification in a malignant skin adnexal tumor. In analogy to breast carcinoma, these findings suggest the applicability of trastuzumab for patients with metastatic adnexal carcinomas demonstrating Her-2/neu amplification.

Axillary lymph node dissection for breast cancer utilizing Harmonic Focus®

2011-08-01

Full Text Available Abstract Background For patients with axillary lymph node metastases from breast cancer, performance of a complete axillary lymph node dissection (ALND is the standard approach. Due to the rich lymphatic network in the axilla, it is necessary to carefully dissect and identify all lymphatic channels. Traditionally, these lymphatics are sealed with titanium clips or individually sutured. Recently, the Harmonic Focus®, a hand-held ultrasonic dissector, allows lymphatics to be sealed without the utilization of clips or ties. We hypothesize that ALND performed with the Harmonic Focus® will decrease operative time and reduce post-operative complications. Methods Retrospective review identified all patients who underwent ALND at a teaching hospital between January of 2005 and December of 2009. Patient demographics, presenting pathology, treatment course, operative time, days to drain removal, and surgical complications were recorded. Comparisons were made to a selected control group of patients who underwent similar surgical procedures along with an ALND performed utilizing hemostatic clips and electrocautery. A total of 41 patients were included in this study. Results Operative time was not improved with the use of ultrasonic dissection, however, there was a decrease in the total number of days that closed suction drainage was required, although this was not statistically significant. Complication rates were similar between the two groups. Conclusion In this case-matched retrospective review, there were fewer required days of closed suction drainage when ALND was performed with ultrasonic dissection versus clips and electrocautery.

Post-mastectomy pain syndrome (PMPS) is a frequent complication of breast surgery. There is currently no standard definition for this chronic pain syndrome. The purpose of this review was to establish a consensus for defining PMPS by identifying the various elements included in the definitions and how they vary across the literature, determining how these definitions affect the methodological components therein, and proposing a definition that appropriately encompasses all of the appropriate elements. We searched PubMed to retrieve all studies and case reports on PMPS, and we analyzed definitions of PMPS, inclusion/exclusion criteria, and methods of measuring PMPS. Twenty-three studies were included in this review. We identified 7 independent domains for defining PMPS: surgical breast procedure, neuropathic nature, pain of at least moderate intensity, protracted duration, frequent symptoms, appropriate location of the symptoms and exacerbation with movement. These domains were used with varying frequency. Inclusion/exclusion criteria and methods for assessing PMPS also varied markedly. To prevent future discrepancies in both the clinical and research settings, we propose a new and complete definition based on the results of our review: PMPS is pain that occurs after any breast surgery; is of at least moderate severity; possesses neuropathic qualities; is located in the ipsilateral breast/chest wall, axilla, and/or arm; lasts at least 6 months; occurs at least 50% of the time; and may be exacerbated by movements of the shoulder girdle.

histopathologically evaluated. Quadrantectomy was performed in 138 cases and modified mastectomy (Patey, in 4 cases. The predominance of the T1c (130 cases was observed. Results: a total of 3,282 lymph nodes were removed (2,456 at level I and 826 at level II, with an average of 23.1 nodes per axilla. Only 68 were histologically involved (2%. "Skip" metastasis was present only in one case (0.7%. Thirty-five false negative cases were observed (24.6%, with involvement of level I in 34 cases (97.1% and of level II in 2 cases (5.7%. We observed 107 cases with negative axillary lymph nodes (75.4%. Conclusion: the axillary dissection of levels I and II is sufficient to treat the axilla in clinical stage I breast cancer. In clinical stage II and III of the disease, the complete axillary dissection including levels I, II and III is indicated. The interpectoral Rotter group will be removed if surgically suspicious.

To review imaging features of fibrous hamartoma of infancy (FHI), focusing on ultrasonography (US) findings. We retrospectively reviewed pediatric patients who were diagnosed with pathologically confirmed FHI in two children's hospitals from 2004 to 2013. Imaging features of US, Doppler US, and magnetic resonance imaging (MRI) were evaluated. Thirteen pediatric patients (M:F = 7:6; age 5-22 months, mean 11.3 months) were included. Mean lesion size was 3.2 cm (range, 0.7-8.0 cm). The tumors were located in the back (n = 4), scrotum (n = 2), scalp, shoulder, axilla, forearm, intergluteal cleft, inguinal area, and thigh. US was performed in 11 patients. With the exception of two scrotal masses, all masses were located in the dermal and subcutaneous layer. All masses demonstrated heterogeneous hyperechogenicity with a ''serpentine pattern'' of intervening hypoechoic portions in the hyperechoic mass. The margins were ill-defined (n = 9) or lobulated (n = 2). Doppler US was performed in nine patients and showed no (n = 6) or minimal (n = 3) vascularity. MRI was performed in five patients and the masses showed heterogeneous signal intensity with the presence of fat on T1- and T2-weighted images. FHI is a tumor that is typically located in the dermal and subcutaneous layer in young children less than 2 years old and presents as a heterogeneously hyperechoic mass with a ''serpentine pattern'' and ill-defined or lobulated margin on US and no remarkable vascularity on Doppler US.

To evaluate the CT findings of perihepatic tuberculous abscesses. The CT scans of 11 patients (6 females and 5 males) with 14 pathologically proven perihepatic tuberculous abscess were retrospectively evaluated in terms of the morphological characteristics of the abscesses and changes in other abdominal organs and at other sites. A total of 14 absceses were noted in 11 patients. Six (43%) were in the right subphrenic space, three (21%) in the right perihepatic space, three (21%) in the left subphrenic space, and two (14%) in the left perihepatic space. The right side was predominant. The abscesses ranged in size from 1 to 10 (mean, 5) cm in diameter, with a wall thickness of 2-7 (mean, 3) mm. Of the 14 abscesses, 13 were oval, and one spherical. CT findings were as follows : a smooth abscess margin with even wall thickness in seven of the eleven patients (64%); calcification of the wall in two (18%); internal septa in seven (64%); localized fluid collection in nine (82%); lymphadenopathy in five (45%); and peritoneal enhancement in seven (64%). Lesions suggesting tuberculous infection coexisted at other sites in eight patients. These included the lung in six patients (55%), the neck in three (27%), an axilla in two (18%), the liver in two (18%), the spleen in one (9%), and the gastroin-testinal tract in one (9%). CT scanning is useful for establishing the diagnosis of perihepatic tuberculous abscesses by evaluating the morphological characteristics of the mass and by observing changes in other abdominal organs and at other sites.

Lipophilic corynebacteria are involved in the generation of volatile odorous products in the process of human body odor formation by degrading skin lipids and specific odor precursors. Therefore, these bacteria represent appropriate model systems for the cosmetic industry to examine axillary malodor formation on the molecular level. To understand the transcriptional control of metabolic pathways involved in this process, the transcriptional regulatory network of the lipophilic axilla isolate Corynebacterium jeikeium K411 was reconstructed from the complete genome sequence. This bioinformatic approach detected a gene-regulatory repertoire of 83 candidate proteins, including 56 DNA-binding transcriptional regulators, nine two-component systems, nine sigma factors, and nine regulators with diverse physiological functions. Furthermore, a cross-genome comparison among selected corynebacterial species of the taxonomic cluster 3 revealed a common gene-regulatory repertoire of 44 transcriptional regulators, including the MarR-like regulator Jk0257, which is exclusively encoded in the genomes of this taxonomical subline. The current network reconstruction comprises 48 transcriptional regulators and 674 gene-regulatory interactions that were assigned to five interconnected functional modules. Most genes involved in lipid degradation are under the combined control of the global cAMP-sensing transcriptional regulator GlxR and the LuxR-family regulator RamA, probably reflecting the essential role of lipid degradation in C. jeikeium. This study provides the first genome-scale in silico analysis of the transcriptional regulation of metabolism in a lipophilic bacterium involved in the formation of human body odor.

Full Text Available Background: Modified radical mastectomy (MRM is still one of globally accepted surgical techniques for breast cancer and in some selected patient is the gold standard type of surgery. The most frequent complication of this procedure is seroma under skin flaps or in the axilla as reported as much as 30% in some studies. The use of closed suction drainage system to reduce the incidence of this complication has been routinely accepted by surgeons; however, length of catheter stay and the number of catheters inserted in the wound are still controversial. The present study compares the results of single versus double drain insertion in patients undergoing MRM for breast cancer.Materials and Methods: The study was conducted on 100 women with breast cancer who were candidate for MRM surgery during 2007-2010 referred to Modarres hospital, Tehran, Iran as a randomized group matched controlled trial.Results: There was no significant difference between the two groups in terms of age, BMI, and tumor weight (P=0.406 (Table 1. Similarly, the difference between the two groups was insignificant in tumor size (T and number of lymph nodes involved (P=0.145. There was no significant difference between the two groups in timing of axillary drain removal (P=0.064. No significant differences were observed between the two groups in mean aspirated fluid (P=0.071 and mean aspirated sera (P=0.484 after removal of drains.Conclusion: This study revealed one drain insertion in MRM surgery is as effective as two drain and probably less morbidity and cost.

Treatments for major internal bleeding after injury include permissive hypotension to decrease the rate of blood loss, intravenous infusion of plasma or clotting factors to improve clot formation, and rapid surgical hemostasis or arterial embolization to control bleeding vessels. Yet, little is known regarding major internal arterial hemostasis, or how these commonly used treatments might influence hemostasis. (i) To use a swine model of femoral artery bleeding to understand the perivascular hemostatic response to contained arterial hemorrhage. (ii) To directly confirm the association between hemodynamics and bleeding velocity. (iii) To observe the feasibility of delivering an activated clotting factor directly to internal sites of bleeding using a simplified angiographic approach. Ultrasound was used to measure bleeding velocity and in vivo clot formation by elastography in a swine model of contained femoral artery bleeding with fluid resuscitation. A swine model of internal pelvic and axillary artery hemorrhage was also used to demonstrate the feasibility of local delivery of an activated clotting factor. In this model, clots formed slowly within the peri-wound hematoma, but eventually contained the bleeding. Central hemodynamics correlated positively with bleeding velocity. Infusion of recombinant human activated factor VII into the injured artery near the site of major internal hemorrhage in the pelvis and axillae was feasible. We rediscovered that clot formation within the peri-wound hematoma is an integral component of hemostasis and a feasible target for the treatment of major internal bleeding using activated clotting factors delivered using a simplified angiographic approach. © 2015 International Society on Thrombosis and Haemostasis.

Full Text Available Background: Snakebite is a health issue specific to some parts of the world, especially in the tropical area, where it produces many victims. The main clinical damage caused by snake bite involves hemotoxic, neurotoxic and myotoxic reactions. It is also established that the importance of systemic impairment varies according to individual factors and are related to organ dysfunction, shock or hypotension. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome. Case Report: We present the case of a 32-year-old Romanian woman who was injured by her own Crotalinae snake (also known as pit viper or rattlesnake on her left forearm. When admitted to our Emergency Department, she was conscious with a Glasgow coma scale of 12/15, somnolent, febrile, suffering of headache, tachypnea; the marks of the snakebite were located in the distal part of the anterior left forearm; she had pain and bleeding at the bite site and swelling of the left upper limb with lymphangitis up to the axilla. She experienced fasciotomy-requiring compartment syndrome of the upper limb and required unfractionated heparin and closed monitored using activated partial thromboplastin time evolution due micro-thrombosis in the brachial vein. Local improvement was achieved in the next 4 days with progressive diminish of local tenderness and swelling. Conclusion: Limb deep vein thrombosis might be induced by snakebite, despite pro-hemorrhagic general condition induced by the envenomation. High index of clinical suspicion is needed for early diagnosis and timely management which can improve survival of these patients

Positron emission tomography (PET) has become an invaluable part of patient evaluation in surgical oncology. PET is less than optimal for detecting lesions PET-positive lesions can be challenging as a result of difficulties in surgical exposure. We undertook this investigation to assess the utility of a handheld high-energy gamma probe (PET-Probe) for intraoperative identification of 18 F-deoxyglucose (FDG)-avid tumors. Forty patients underwent a diagnostic whole-body FDG-PET scan for consideration for surgical exploration and resection. Before surgery, all patients received an intravenous injection of 7 to 10 mCi of FDG. At surgery, the PET-Probe was used to determine absolute counts per second at the known tumor site(s) demonstrated by whole-body PET and at adjacent normal tissue (at least 4 cm away from tumor-bearing sites). Tumor-to-background ratios were calculated. Thirty-two patients (80%) underwent PET-Probe-guided surgery with therapeutic intent in a recurrent or metastatic disease setting. Eight patients underwent surgery for diagnostic exploration. Anatomical locations of the PET-identified lesions were neck and supraclavicular (n = 8), axilla (n = 5), groin and deep iliac (n = 4), trunk and extremity soft tissue (n = 3), abdominal and retroperitoneal (n = 19), and lung (n = 2). PET-Probe detected all PET-positive lesions. The PET-Probe was instrumental in localization of lesions in 15 patients that were not immediately apparent by surgical exploration. The PET-Probe identified all lesions demonstrated by PET scanning and, in selected cases, was useful in localizing FDG-avid disease not seen with conventional PET scanning.

Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay (IFA) for the detection of IgM antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%. PMID:26261776

Purpose: The effectiveness of radiation therapy (RT) in reducing local recurrence after breast-conserving surgery (BCS) in unselected patients with early stage invasive breast cancer has been demonstrated in multiple randomized trials. Whether a subset of women can achieve local control without RT is unknown. In 1986, we initiated a prospective one-arm trial of BCS alone for highly selected breast-cancer patients. This report updates those results. Methods and Materials: Eighty-seven (of 90 planned) patients enrolled from 1986 until closure in 1992, when a predefined stopping boundary was crossed. Patients were required to have a unicentric, T1, pathologic node-negative invasive ductal, mucinous, or tubular carcinoma without an extensive intraductal component or lymphatic-vessel invasion. Surgery included local excision with margins of at least 1 cm or a negative re-excision. No RT or systemic therapy was given. Results: Results are available on 81 patients (median follow-up, 86 months). Nineteen patients (23%) had local recurrence (LR) as a first site of failure (average annual LR: 3.5 per 100 patient-years of follow-up). Other sites of first failure included 1 ipsilateral axilla, 2 contralateral breast cancers, and 4 distant metastases. Six patients developed other (nonbreast) malignancies. Nine patients have died, 4 of metastatic breast cancer and 5 of unrelated causes. Conclusions: Even in this highly selected cohort, a substantial risk of local recurrence occurred after BCS alone with margins of 1.0 cm or more. These results suggest that with the possible exception of elderly women with comorbid conditions, radiation therapy after BCS remains standard treatment

Background and aims: Radiation induced wet desquamation of skin in carcinoma breast patients is a painful condition. In this study topical beclomethasone dipropionate spray was used as prophylaxis with the purpose of reducing risk of the wet desquamation of skin in irradiated field. Materials and methods: sixty patients of carcinoma breast were planned for postoperative loco regional radiotherapy (50 Gy in 25 fraction over five weeks) were prospectively randomized into two groups (1) steroid group-patients were advised to use beclomethasone dipropionate spray in irradiated axilla from day one of radiotherapy, (2) control group-patients were not allowed to use any topical agent in irradiated area. Radiation induced skin reaction was noted in terms of erythema, dry desquamation and wet desquamation weekly till end of prescribed 50Gy dose of the radiation therapy. Statistical method: Chi-square test was used to see the statistical significance of the difference in wet desquamation between two arms of the study. Chi-square value and P-value was calculated for the difference of wet desquamation in two study arms. Result: In steroid group 4/30 (13.33%) patients developed wet desquamation of the axillary skin at the end of the radiotherapy. For the control group, this figure was 11/30 (36.66%). The difference in wet desquamation of the axillary skin in the two groups was statistically significant (P-value=0.0369). Conclusion: Topical steroid (beclomethasone dipropionate spray) for skin during radiotherapy significantly reduces the risk of wet desquamation of the skin. (author)

The efficacy of the long-pulsed diode laser (LPDL) in hair removal is determined with various physical parameters. Recently, LPDLs with a larger spot size are commercially available; however, the independent effect of spot size on hair removal has not been studied. This study aimed to compare the efficacy of the LPDL in hair removal depending on the spot size. A randomized, evaluators-blind, intrapatient comparison (left vs. right) trial was designed. Ten healthy Korean women received three hair removal treatment sessions on both armpits with the 805-nm LPDL and followed for 3 months. A 10×10 mm handpiece (D1) or a 10×30 mm handpiece (D3) was randomly assigned to the right or left axilla. The fluence, pulse duration, and epidermal cooling temperature were identical for both armpits. Hair clearance was quantified with high-resolution photos taken at each visit. Postprocedural pain was quantified on a visual analogue scale. Adverse events were evaluated by physical examination and the patients' self-report. The mean hair clearance at 3 months after three treatment sessions was 38.7% and 50.1% on the armpits treated with D1 and D3, respectively (p=0.028). Procedural pain was significantly greater in the side treated with D3 (p=0.009). Serious adverse events were not observed. Given that the pulse duration, fluence, and epidermal cooling were identical, the 805-nm LPDL at the three times larger spot size showed an efficacy improvement of 29.5% in axillary hair removal without serious adverse events.

Preoperative sentinel lymph node (SLN) mapping by lymphoscintigraphy is helpful to evaluate extra-axillary SLNs over a wider range than the blue dye method. However, the clinical value of extra-axillary SLNs remains uncertain. The goal of this study was to determine the prevalence and clinical significance of supra- or infraclavicular drainage on preoperative lymphoscintigraphy in women with breast cancer. We retrospectively reviewed the files of 942 consecutive breast cancer women who underwent preoperative lymphoscintigraphy for SLN biopsy at our institution between April 2004 and March 2015. Supra- or infraclavicular drainage was detected in 5/942 women (0.5%) on preoperative lymphoscintigraphy. An axillary hot spot was detected in all five women, and a positive axillary SLN was detected in four women. Breast tumor locations were the upper inner or outer quadrants in four women and the lower outer quadrant in one woman. The median follow-up period was 75 months (mean: 92; range: 26-111 months). Recurrence outside the axilla was found in three (60%) women. The woman with a negative SLN status did not undergo adjuvant chemotherapy, but developed extra-axillary lymph node recurrence 3 years after primary surgery. No patient died of metastatic breast cancer at the last follow-up. The detection of the supra- or infraclavicular SLNs on lymphoscintigraphy may provide additional staging information to tailor individual treatment regimens with regard to the potential risk of recurrence or metastasis of breast cancer.

The optimal treatment of ductal carcinoma in situ (DCIS) of the breast has not yet been established. The effectiveness of adjuvant postoperative radiotherapy after conservative surgery is debated. Few data are available in Italy on the combined treatment. A collaborative multi-institutional study on this issue in 10 radiation oncology departments of the north-east of Italy was conducted. One hundred and thirty nine women with DCIS of the breast were treated between 1980 and 1990. Age ranged between 28 and 88 years (median 50 years). Surgical procedures were: quadrantectomy in 108, lumpectomy in 22 and wide excision in 9 cases. The axilla was surgically staged in 97 cases: all the patients were node-negative. Radiation therapy was delivered with 60Co units (78%) or 6 MV linear accelerators (22%) for a median total dose to the entire breast of 50 Gy (mean 49.48 Gy; range 45-60 Gy). The tumour bed was boosted in 109 cases (78%) at a dose of 4-30 Gy (median 10 Gy) for a minimum tumour dose of 58 Gy. Median follow-up was 81 months. Thirteen local recurrences were recorded, 7 intraductal and 6 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease. Actuarial overall, cause-specific and recurrence-free survival at 10 years are of 93%, 100% and 86%, respectively. The results of this retrospective multicentric study substantiate the favourable data reported in the literature and confirm the efficacy of the breast-conserving treatment of DCIS employing conservative surgery and adjuvant radiation therapy.

Full Text Available Objective: Patients with locally advanced breast cancer may undergo breast conserving surgery after neoadjuvant chemotherapy. The aim of the study is to evaluate the results of locally advanced breast cancer patients who underwent breast conserving surgery, axillary dissection and sentinel lymph node biopsy in a single center. Material and Methods: 12 patients with locally advanced breast cancer stage IIIA/IIIB were included in the study between 2002-2009. The patients were given anthracycline-based regimen before surgery. Patients underwent breast conserving surgery, axillary dissection, and sentinel lymph node biopsy followed by radiotherapy. Results: There were five patients in stage IIIA, six in stage IIIB, and one in stage IIIC. Patients had received 3-6 regimen of FAC/FEC. Eight had partial and four had complete response. Five positive axilla were detected. The median value of the lymph nodes was 12 (n:8-19. Five patients underwent sentinel lymph node biopsy. The biopsy has failed in one patient and the median value of dissected sentinel node was 3.5 (n:3-4. Locoregional recurrence was not observed in any patients. The mean follow-up of the patients was 29.8 months and median time was 16 (n:2-80 months.Of the 12 patients 10 are alive and 2 were deceased. Conclusion: In selected locally advanced patients, breast conserving surgery and sentinel lymph node biopsy may be applied by a multidisciplinary approach, and excellent success may be achieved in those patients as in early breast cancer patients.

Purpose: To investigate lymphatic drainage as measured by lymphoscintigraphy in the arms of patients undergoing either sentinel lymph node biopsy (SNB) or axillary lymph node dissection (ALND). Material and Methods: From January 2001 to December 2002, 30 patients with unilateral invasive breast carcinoma underwent breast-conserving surgery with SNB and 30 patients with ALND. All patients received radiotherapy to the breast. Lymphoscintigraphy was performed, and skin circulation, skin temperature, and arm volume were measured 2-3 years after radiotherapy. Results: None of the 30 patients who underwent SNB showed any clinical manifestation of lymphedema. Of the 30 patients undergoing ALND, six (20%) had clinical lymphedema, with an arm volume that was >10% larger on the operated than on the non-operated side (P<0.01). Scintigraphically, visual analysis revealed lymphatic dysfunction in three patients, manifested as forearm dermal back flow. Two of these patients also had an increased arm volume. Quantitative analysis showed no differences between the groups, apart from a smaller amount of isotope in the axilla in the ALND group. There was no difference in skin circulation or skin temperature. Conclusion: Our study shows that lymph drainage in the operated arm compared with the non-operated arm was less affected by SNB than by ALND, and that morbidity associated with SNB was lower than with ALND. However, the results do not confirm our hypothesis that lymphoscintigraphy can reveal differences in lymph circulation that are not evident clinically in the form of manifest lymphedema. The most sensitive clinical method of assessing lymph drainage seems to be measurement of arm volume

The aim of this systematic review was to summarize and systematize the information about physical symptoms and its relation with work activity on female Breast Cancer Survivors (BCS). A systematic search was performed on the databases MEDLINE/PubMed (via National Library of Medicine), SCOPUS (Elsevier), Web of Science (Thomson Reuters Scientific) and CINAHL with full text (EBSCO), including papers about physical impairments experienced by female workers who have had breast cancer. The search retrieved 238 studies, and another 5 were identified in the articles' references, totaling 243 papers. After removing duplicates and applying the inclusion criteria and a full text reading, 13 articles were included for qualitative analysis. Concerning physical limitations, most complaints were related to the elevation of upper limbs, carrying heavy objects, driving and holding manual movements. The most referred symptoms were breast/arm pain, fatigue, lymphedema, reduced range of motion and weakness in the upper limbs, scar tissue adherence in the breast/axilla and paresthesia in the arm/breast. These symptoms and physical limitations led to the difficulty or impossibility of performing work tasks, which also diminished work productivity, as well as the increase in time to return to work. The present results suggest higher unemployment rates and the need for modifying work conditions. Implication for Rehabilitation Health professionals should include risk assessment at daily routine to identify possible sources of physical impairments for upper limbs. Provide the support and orientations according to personal and job characteristics of the patient. Focus the aims of treatment over upper limbs impairments, reducing the prevalence and the gravity of symptoms.

The conflicting needs of homeostasis in air versus water complicate our understanding of thermoregulation in marine mammals. Large-scale modeling efforts directed at predicting the energetic impact of changing sea ice conditions on polar ecosystems require a better understanding of thermoregulation in air of free-ranging animals. We utilized infrared imaging as an indirect approach to determine surface temperatures of dry, hauled-out Weddell seals (Leptonychotes weddellii, n = 35) of varying age and body condition during the Antarctic summer. The study groups provided a fivefold range in body mass and a threefold range in blubber depth. Surface temperature (T s) did not vary by body region (head, shoulder, axilla, torso, hip, flippers). Average seal T s (mean 13.9 ± 11.2 °C) was best described through a combination of the physical traits of body mass and environmental variables of ambient temperature T air, and wind speed. Additional factors of ice temperature (T ice), relative humidity and cloud cover did not improve the model. Heat transfer model estimates suggested that radiation contributed 56.6 ± 7.7 % of total heat loss. Convection and conduction accounted for the remaining 15.7 ± 12.3 and 27.7 ± 9.3 %, respectively. Heat loss by radiation was primarily influenced by body mass and wind speed, whereas convective heat loss was influenced primarily by blubber depth and wind speed. Conductive heat loss was modeled largely as a function of physical traits of mass and blubber depth rather than any environmental covariates, and therefore was substantially higher in animals in leaner condition.

Breast engorgement is a major cause of pain and weaning in the early postpartum period. While protocols reinforce the need for anticipatory engorgement advice and continued outpatient health professional breastfeeding support, there remains limited information on the efficacy of focused postdischarge engorgement education. This study sought to explore if outpatient postpartum engorgement education changed mothers' home management and if mothers found instruction on specific massage and hand expression techniques helpful. This was a prospective descriptive cohort study. Subjects received engorgement-specific postpartum support from a healthcare professional at the posthospital discharge (PD) newborn visit. Email surveys at 1, 2, and 12 weeks postpartum collected data on engorgement home management, clinical course, and postpartum education. After the office visit, mothers changed their engorgement home management. Significantly more mothers utilized massage toward the axillae (25% versus 1%, p ≤ 0.001), reverse pressure softening (18% versus 3%, p = 0.001), and feeding more frequently (32% versus 16%, p = 0.04). Sixty-one percent would not have used massage and hand expression before education in the office. At 12 weeks, 96% of women reported massage and hand expression instruction as helpful. Mothers reported engorgement peaked at a median of 5 days postpartum, corresponding well to the office visit at a median of 4 days postpartum. Maternal engorgement symptoms are commonly present at the PD newborn visit. Education on engorgement, massage, and hand expression at this visit significantly changes home management strategies. Mothers find massage and hand expression instruction helpful.

Breast cancer is the most common malignancy among women. Surgical treatment is an essential part of therapy, which still includes chemotherapy, radiotherapy and hormone therapy. The increase in early cancer detection and less aggressive treatment has made longer survival rates possible for women with this neoplasia. Morbidities after treatment have subsequently aroused particular interest in the scientific community in order to minimize their effects and provide increased quality-of-life for these patients. The present study aimed at investigating one of these morbidities: axillary web syndrome, which occurs after axillary surgical management. From December 2011 to September 2012, according to the inclusion and exclusion criteria, 97 patients, who had been surgically treated for breast cancer, were enrolled, interviewed, and submitted to a specific physical exam. An investigation of the axillary cords, characteristic of this syndrome, was performed in all patients. The axillary web syndrome was diagnosed in 28.86% of the women. Higher risk of triggering the syndrome has been associated with younger age (21.7%), longer time between first treatment and data collection (29.3%), greater number of resected lymph nodes (149.7%) and surgical management medical teams (113.2%). One can conclude that axillary web syndrome was associated with younger age, greater time elapsed since surgery, surgical management of medical staff and number of resected lymph nodes. Further studies are needed to review prior-to-surgery and post-operative follow-up, to properly assess the effects of surgery in the axilla on homeostatic balance, not only in the ipsilateral upper limb, but also assess their compensatory consequences throughout the body.

Purpose: To report the results of a detailed analysis of treatment failures after MammoSite breast brachytherapy for partial breast irradiation from our single-institution experience. Methods and Materials: Between October 14, 2002 and October 23, 2006, 78 patients with early-stage breast cancer were treated with breast-conserving surgery and accelerated partial breast irradiation using the MammoSite brachytherapy applicator. We identified five treatment failures in the 70 patients with >6 months' follow-up. Pathologic data, breast imaging, and radiation treatment plans were reviewed. For in-breast failures more than 2 cm away from the original surgical bed, the doses delivered to the areas of recurrence by partial breast irradiation were calculated. Results: At a median follow-up time of 26.1 months, five treatment failures were identified. There were three in-breast failures more than 2 cm away from the original surgical bed, one failure directly adjacent to the original surgical bed, and one failure in the axilla with synchronous distant metastases. The crude failure rate was 7.1% (5 of 70), and the crude local failure rate was 5.7% (4 of 70). Estimated progression-free survival at 48 months was 89.8% (standard error 4.5%). Conclusions: Our case series of 70 patients with >6 months' follow-up and a median follow-up of 26 months is the largest single-institution report to date with detailed failure analysis associated with MammoSite brachytherapy. Our failure data emphasize the importance of patient selection when offering partial breast irradiation

Full Text Available Background: Until very recently mantle field radiotherapy remained the gold standard for the treatment of favorable early-stage Hodgkin′s lymphoma. The classic mantle includes all the major lymph nodes above the diaphragm and extends from the inferior portion of the mandible to the level of the insertion of the diaphragm. Aims: To describe a simple technique that has been devised to treat the mantle field with the help of multileaf collimator and using computed tomography (CT-based treatment planning. Materials and Methods: CT scan was performed with the patient in the supine position and the datasets were transferred to the Eclipse™ treatment planning system. Elekta Precise™ linear accelerator equipped with 40 pairs of multileaf collimator (MLC was used for the execution of the mantle field. The MLC′s shapes were designed to take the shape of the conventional customized blocks used for treatment of mantle field. The anterior mantle field was divided into three separate MLC segments with the collimator kept at 0°. The first MLC segment was shaped to cover the neck, clavicular regions, and mediastinum. The second and the third MLC segments covered the right and left axilla, respectively. The posterior fields were opposed to the anterior subfields in a similar fashion. The dose was prescribed at the midplane, using reference points. Results and Conclusion: The technique described in this study is very simple, easy to implement, and avoids unnecessary delay in the execution of the mantle field. The mantle field can be easily shaped with the multileaf collimators, without any collimator rotation.

Background: We assessed the utility of enhanced magnetic resonance imaging (MRI) using ultrasmall superparamagnetic iron oxide (USPIO) in the evaluation of axillary lymph node metastases in patients with breast cancer. Study design: MR examination of the axilla was performed before and 24-36 h after USPIO administration for patients with stage II or III breast cancer. Diagnostic performance was compared using size criteria (metastasis was defined when short axis diameter >5 or >10 mm) or morphologic criteria on conventional MRI, the combined study of USPIO precontrast and postcontrast images, and USPIO postcontrast study alone. Results: A total of 622 nodes (503 metastatic and 119 nonmetastatic nodes) were dissected from 33 patients. The results of conventional MRI for nodes >5 mm were 59.1% sensitivity, 86.7% specificity, and 80.4% overall accuracy. Results for nodes >10 mm were 15.7% sensitivity, 99.2% specificity, and 80.2% overall accuracy. Results based on morphology were 36.5% sensitivity, 94.1% specificity, and 81.0% overall accuracy. The results of the combined study of USPIO precontrast and postcontrast images were 86.4% sensitivity, 97.5% specificity, 91.1% positive predictive value, 96.1% negative predictive value, and 95.0% overall accuracy. The results of USPIO postcontrast images alone were 84.7% sensitivity, 96.8% specificity, and 94.0% overall accuracy. Patient-based results of postcontrast USPIO study alone were 100.0% sensitivity, 80.0% specificity, and 93.9% overall accuracy. Conclusions: USPIO postcontrast study alone was useful in the assessment of axillary lymph node metastases in patients with breast cancer

As breast cancer survivors are benefiting increasingly from advanced forms of therapy, the side effects of locoregional treatment in the adjuvant setting are becoming more and more important. This article presents a new method of assessing the spatial distribution of paresthesia in breast cancer survivors after different locoregional treatments. A structured questionnaire assessing paresthesia, with body pictograms for marking paresthesia areas, was completed by 343 breast cancer survivors. The image information was digitized, generating gray-scale summation images with numbers from 0, indicating black (100 % of the patients had paresthesia), to 255, indicating white (none had paresthesia). The resulting map visualization showed the locations of paresthesia on body pictograms. The group included patients who had undergone breast-conserving surgery (BCS) and mastectomy, and also patients who had received percutaneous and interstitial radiation. A total of 56.5 % of the patients stated that they had paresthesia. The paresthesia areas were distributed within the range suggested by clinical experience. Most patients stated that they had paresthesia in the upper outer quadrant and axilla. Patients who had undergone mastectomy or percutaneous radiotherapy appeared to have more paresthesia on some areas of the body surface. Patients who had undergone mastectomy indicated larger areas of paresthesia than those with BCS-4,066 pixels (px) vs. 2,275 px. Radiotherapy did not appear to influence the spatial distribution of paresthesia. Paresthesia is a common symptom after breast cancer treatment. This paper describes a new method of assessing this side effect to improve and individualize treatment for it in the future.

Current trends in patient care include the desire for minimizing invasiveness of procedures and interventions. This aim is reflected in the increasing utilization of sentinel lymph node biopsy, which results in a lower level of morbidity in breast cancer staging, in comparison to extensive conventional axillary dissection. Optimized lymphoscintigraphy with triangulated body marking is a clinical option that can further reduce morbidity, more than when a hand held gamma probe alone is utilized. Unfortunately it is often either overlooked or not fully understood, and thus not utilized. This results in the unnecessary loss of an opportunity to further reduce morbidity. Optimized lymphoscintigraphy and triangulated body marking provides a detailed 3 dimensional map of the number and location of the sentinel nodes, available before the first incision is made. The number, location, relevance based on time/sequence of appearance of the nodes, all can influence 1) where the incision is made, 2) how extensive the dissection is, and 3) how many nodes are removed. In addition, complex patterns can arise from injections. These include prominent lymphatic channels, pseudo-sentinel nodes, echelon and reverse echelon nodes and even contamination, which are much more difficult to access with the probe only. With the detailed information provided by optimized lymphoscintigraphy and triangulated body marking, the surgeon can approach the axilla in a more enlightened fashion, in contrast to when the less informed probe only method is used. This allows for better planning, resulting in the best cosmetic effect and less trauma to the tissues, further reducing morbidity while maintaining adequate sampling of the sentinel node(s).

Breast conserving surgery (BCS) has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy (ESM) plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting. From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups (P > 0.05). The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM (88.4%, 38/43) and BCS (92.6%, 50/54) patients (P > 0.05). During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence -one of these patients died of multiple organ metastasis. After considering the wide indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants - the new surgery of choice for breast cancer - warrants serious consideration as the prospective next standard surgical procedure.

To evaluate the radiation protective characteristics of a system designed to enhance operator protection while eliminating weight to the body and allowing freedom of motion. Radiation doses to a mock interventionalist were measured with calibrated dosimeters in a clinical interventional suite. A standard lead apron (SLA; Pb equivalent, 0.5 mm) was compared with a suspended radiation protection system (ZeroGravity; Zgrav) that shields from the top of the head to the calves (except the right arm and left forearm) with a complex overhead motion system that eliminates weight on the operator and allows freedom of motion. Zgrav included a suspended lead apron with increased lead equivalency, greater length, proximal left arm and shoulder coverage, and a wraparound face shield of 0.5 mm Pb equivalency. A 26-cm-thick Lucite stack (ie, mock patient) created scatter during 10 controlled angiography sequences of 120 exposures each. Parameters included a field of view of 40 cm, table height of 94 cm, 124 cm from the tube to image intensifier, 50 cm from the image center to operator, 66 kVp, and 466-470 mA. Under identical conditions, average doses (SLA vs Zgrav) were 264 versus 3.4 (ratio, 78) to left axilla (P < .001), 456 versus 10.2 (ratio, 45) to left eye (P < .001), 379.4 versus 6.6 (ratio, 57) to right eye (P < .005), and 18.8 versus 1.2 (ratio, 16) to gonad (P < .001). Relative to a conventional lead apron, the Zgrav system provided a 16-78-fold decrease in radiation exposure for a mock interventionalist in a simulated clinical setting. Copyright © 2011 SIR.

Autism spectrum disorders comprise a range of neurodevelopmental pathologies characterized, among other symptoms, by impaired social interactions. Individuals with this diagnosis are reported to often identify people by repetitively sniffing pieces of clothing or the body odor of family members. Since body odors are known to initiate and mediate many different social behaviors, smelling the body odor of a family member might constitute a sensory-based action promoting social contact. In light of this, we hypothesized that the body odor of a family member would facilitate the appearance of automatic imitation, an essential social skill known to be impaired in autism. We recruited 20 autistic and 20 typically developing children. Body odors were collected from the children's mothers' axillae. A child observed a model (their mother or a stranger mother) execute (or not) a reach-to-grasp action toward an object. Subsequently, she performed the same action. The object was imbued with the child's mother's odor, a stranger mother's odor, or no odor. The actions were videotaped, and movement time was calculated post hoc via a digitalization technique. Automatic imitation effects-expressed in terms of total movement time reduction-appear in autistic children only when exposed to objects paired with their own mother's odor. The maternal odor, which conveys a social message otherwise neglected, helps autistic children to covertly imitate the actions of others. Our results represent a starting point holding theoretical and practical relevance for the development of new strategies to enhance communication and social behavior among autistic individuals.

Malignant rhabdoid tumours (RT) are increasingly recognized in young children, probably as a consequence of advances in accurate histological diagnosis rather than a true increase in frequency. Although typically presenting as renal tumours in infancy, extrarenal tumours outside the central nervous system (CNS) in children less than 12 months of age are now well recognized, but previous literature on their imaging features is very limited. To demonstrate the imaging features of extrarenal RTs outside the CNS. A retrospective database review was made from 1989 to 2007 of patients diagnosed with extrarenal RT in infancy, i.e. below 12 months of age. There were nine patients (six boys and three girls). The age at presentation varied from 1 to 11 months (average 6 months). Tumours were located in the thorax/mediastinum (n=3), liver (n=3), neck (n=1), shoulder (n=1) and axilla (n=1). The imaging modalities used included US (n=8), CT (n=7) and MRI (n=6). Bone scan was positive in one patient, while metastases at the time of diagnosis occurred in four patients. On MRI the tumours tended to show nonspecific hypointensity on T1-W images and heterogeneous hyperintensity on T2-W images, with heterogeneous enhancement. This is the largest radiological series of extrarenal RTs outside the CNS in infancy. In our series no imaging features were found specific to the diagnosis. A tendency towards large size and mediastinal/paravertebral location were noted. A hypodense solid component on CT and a heterogeneous hyperintensity on T2-W MR images suggest that this tumour should be considered in the routine differential diagnosis of soft-tissue tumours in infancy, in addition to rhabdomyosarcoma.

Full Text Available OBJECTIVE: To evaluate ipsilateral breast tumor recurrence after breast-conserving surgery for locally advanced breast cancer. METHODS: A retrospective observational cohort study was performed in patients with locally advanced breast cancer submitted to breast-conserving surgery after neoadjuvant chemotherapy based on an adriamycin-cyclophosphamide-paclitaxel regimen. We evaluated the clinical, pathologic, immunohistochemistry, and surgical factors that contribute to ipsilateral breast tumor recurrence and locoregional recurrence. A Kaplan-Meier analysis and Cox model were used to evaluate the main factors related to disease-free survival. RESULTS: Of the 449 patients who received neoadjuvant chemotherapy, 98 underwent breast-conserving surgery. The average diameter of the tumors was 5.3 cm, and 87.2% reached a size of up to 3 cm. Moreover, 86.7% were classified as clinical stage III, 74.5% had T3-T4 tumors, 80.5% had N1-N2 axilla, and 89.8% had invasive ductal carcinoma. A pathologic complete response was observed in 27.6% of the tumors, and 100.0% of samples had free margins. The 5-year actuarial overall survival rate was 81.2%, and the mean follow-up was 72.8 months. The rates of ipsilateral breast tumor recurrence and locoregional recurrence were 11.2% and 15.3%, respectively. Multifocal morphology response was the only factor related to ipsilateral breast tumor recurrence disease-free survival (p=0.04. A multivariate analysis showed that the pathologic response evaluation criteria in solid tumors (RECIST-breast cutoff was the only factor related to locoregional recurrence disease-free survival (p=0.01. CONCLUSIONS: Breast-conserving surgery is a safe and effective therapy for selected locally advanced breast tumors.

We should use a computed tomography-simulator for the body measure and compensator manufacture process was practiced with TBI's positioning in process and to estimate the availability. Patient took position that lied down. and got picture through computed tomography-simulator. This picture transmitted to Somavision and measured about body measure point on the picture. Measurement was done with skin, and used the image to use measure the image about lungs. We decided thickness of compensator through value that was measured by the image. Also, We decided and confirmed position of compensator through image. Finally, We measured dosage with TLD in the treatment department. About thickness at body measure point. we could find difference of 1-2 cm relationship general measure and image measure. General measure and image measure of body length was seen difference of 3-4 cm. Also, we could paint first drawing of compensator through the image. The value of dose measurement used TLD on head, neck, axilla, chest(lungs inclusion), knee region were measured by 92-98% and abdomen, pelvis, inquinal region, feet region were measured by 102-109%. It was useful for TBI's positioning to use an image of computed tomography-simulator in the process. There was not that is difference of body thickness measure point, but measure about length was achieved definitely. Like this, manufacture of various compensator that consider body density if use image is available. Positioning of compensator could be done exactly, and produce easily without shape of compensator is courted Positioning in the treatment department could shortened overall 15 minute time. and reduce compensator manufacture time about 15 minutes.

Removal of unwanted hair is the most popular skin treatment worldwide. Over the past decade, various lasers and light sources for epilation have been advocated for use in an office setting, although most people continue to treat unwanted hair with a variety of temporary physical methods (e.g., waxing, shaving) in a home setting, presumably due to cost and convenience factors. To evaluate the safety and efficacy of a low-energy pulsed-light device intended for home-use hair removal. Twenty women (skin phototypes I-IV) with dark terminal hair in nonfacial sites (axilla, forearms, inguinal region, legs) self-administered three treatments at 2-week intervals using a handheld intense-pulsed-light device. Matched untreated skin sites were also studied. Hair counts and clinical photographs were obtained pretreatment and at 1, 3, and 6 months after the third treatment. Side effects and patient satisfaction scores were recorded. All patients showed a positive clinical response to treatment, with reduction of unwanted hair. No reduction of hair was noted in untreated matched areas. Hair counts were reduced 37.8% to 53.6% 6 months after the three treatments. Skin region influenced clinical response, with lower legs exhibiting greater hair reduction than arms and inguinal and axillary areas. Mild erythema was experienced in 25% of patients, but no other side effects or complications were encountered. Patient satisfaction scores were high, with all patients stating that they would purchase the device for future home use. CONCLUSIONS Low-energy pulsed light can be applied safely and effectively for at-home hair removal in a variety of nonfacial locations and skin phototypes I-IV.

A prospective cohort study was undertaken to determine the clonal dynamics of Staphylococcus aureus colonization and infection during 1 y in children with atopic dermatitis, and to correlate specific clones, accessory gene regulator (agr) groups, and production of virulence factors with eczema activity. Eleven children were examined every 6 wk with swaps taken from active eczema, anterior nose, axillae and perineum, and scoring of eczema activity by severity scoring of atopic dermatitis (SCORAD). Individual S. aureus clonal types were identified and examined for production of superantigens, toxins, and were assigned to agr groups. S. aureus colonization patterns ranged from rare colonization over transient colonization to persistent colonization by a single clone or a dynamic exchange of up to five clones. Production of no single virulence factor including superantigens and toxins was significantly associated with exacerbation of eczema. In four children there was a shift between visits in agr group of colonizing clones. These shifts were associated with an increased SCORAD value of 19 (SE = 7, p = 0.009). Change of clones belonging to the same agr group was not associated with a higher SCORAD value. In 11 of 12 cases with two different clones co-colonizing a child the clones belonged to the same agr group. In conclusion, this limited group of children with atopic dermatitis showed highly variable colonization patterns of S. aureus, and communication between strains by use of agr encoded octa peptides appeared to be active in vivo. Increased severity of eczema was related to a change in agr group and may have been because of inflammation triggered by the takeover of an antigenically different clone, as agr groups represent ancient phylogenetic lineages.

The gorgonian Isis hippuris contains secondary metabolites gorgosterol and hippuristanol which are capable of inhibiting cancer cells. However, in vivo test of the gorgonian Isis hippuris extract as the anticancer drug has not been conducted. The research to study of the effect of ethanolic extract of the gorgonian on the induced tumor growth in C3H mice. The I. hippuris was obtained from Karimunjawa water in Jepara. The extract was prepared by maceration using ethanol. A total 20, 8-10 moths old of C3H mice with an initial weight of 20-25 gram were assigned into control, Ih-1, Ih-2, and Ih-3 groups. Control, Ih-1, Ih-2, and Ih-3 groups each received 0, 0.15, 1.5, and 15 mg extract per mouse per day respectively for two weeks. Cancer cells were introduced to all groups from a donor cancer mouse by injection via left or right axilla and allowed to grow. The cancer mass was removed and processed for histological examination, and cancer growth was determined according to Elston and Ellis criteria. The result showed that histological grade of cancer mass from the control group was in grade 2 or differentiated moderately. The histological grade of cancer mass from Ih-1, Ih-2, and Ih-3 groups were in grade 1 (low grade) or similar to a normal cell. Statistical analysis by Kruskal-Wallis test showed a significant difference (ptest found no significant differences among Ih-1, Ih-2, and Ih-3 treated mice. The results indicated the potential of active substances in the ethanol extract of I. hippuris as an anti-cancer drug.

Full Text Available (1 Background: The purpose of this retrospective study was to evaluate the recurrence and survival rates of metastatic melanoma of unknown primary origin (MUP, in order to further refine current recommendations for the surgical treatment; (2 Methods: Medical data of all MUP patients registered between 2000 and 2011, were analyzed. Seventy-eight patients were categorized in either lymph node (axilla, groin, head-and neck or subcutaneous MUP. Axillary node MUPs were generally treated with dissections of levels I-III, inguinal node MUPs with combined superficial and deep groin dissections, and head-and-neck node MUPs with neck dissections to various extents, based on lymph drainage patterns. Subcutaneous lesions were excised with 1–2 cm margins. The primary outcome was treatment outcomes in terms of (locoregional recurrence and survival rates; (3 Results: Lymph node MUP recurred regionally in 11% of patients, with an overall recurrence rate of 45%. In contrast, subcutaneous MUP recurred locally in 65% of patients with an overall recurrence rate of 78%. This latter group had a significantly shorter disease-free interval than patients with lymph node MUP (p = 0.000. In the entire study population, 5-year and 10-year overall survival rates were 56% and 47% respectively, with no differences observed between the various subgroups; (4 Conclusion: The relatively low regional recurrence rate after regional lymph node dissection (11% supports its current status as standard surgical treatment for lymph node MUP. Subcutaneous MUP, on the contrary, appears to recur both locally (65% and overall (78% at a significantly higher rate, suggesting a different biological behavior. However, wide local excision remains the best available option for this specific group.

INTRODUCTION: Recent decades have seen a significant shift towards conservative management of the axilla. Increasingly, immunohistochemical analysis of sentinel nodes leads to the detection of small tumour deposits, the significance of which remains uncertain. The aims of this study are to examine patients whose sentinel lymph nodes are positive for macro-metastasis, micro-metastasis or isolated tumour cells (ITCs) and to determine the rate of further nodal disease after axillary lymph node dissection (ALND). METHODS: A retrospective analysis of all patients undergoing a sentinel lymph node biopsy (SLNB) between January 2007 and December 2010 in a tertiary referral breast unit was performed. Patients who underwent an axillary lymph node dissection for macro-metastasis, micro-metastasis or ITCs were identified. Demographics, histological data and the rate of further axillary disease were examined. RESULTS: In total, 664 breast cancer patients attended the symptomatic breast unit during the study period, 360 of whom underwent a SLNB. Seventy patients had a SLNB positive for macro-metastasis. All of these patients underwent ALND. A positive SLNB with either micro-metastasis or ITCs was identified in 58 patients. Only 41 of the 58 patients went on to have an ALND, due primarily to variations in surgeons\\' preferences. Nineteen patients with micro-metastasis underwent an ALND. Four patients had further axillary disease (21%). Twenty-two patients had ITCs identified, of whom only one had further disease (4.5%). No statistically significant difference was found between the two groups in terms of tumour size, grade, lymphovascular invasion or oestrogen receptor status. CONCLUSION: ALND should be considered in patients with micro-metastasis at SLNB. It should rarely be employed in the setting of SLNB positive for ITCs.

Rupture of the pectoralis major: a case report and review.

Rupture of the pectoralis major muscle is a rare clinical entity that is becoming more common due to the increasing popularity of weightlifting and recreational sports. Due to the rarity of this condition, it may be missed at initial presentation and inappropriately treated, potentially leading to increased disability. This case highlights the mechanism of injury, clinical features, diagnosis, and treatment of rupture of the pectoralis major. The patient was a 31-year-old male bodybuilder who presented to the Emergency Department with acute pain and swelling in the left axilla after performing a bench press with a 400-pound barbell. The diagnosis of pectoralis major rupture was suspected and confirmed by magnetic resonance imaging, and early surgical repair was performed. The most common mechanism of injury is excessive tension on a maximally contracted pectoralis major muscle. Weightlifting, specifically bench pressing, is a common cause. The diagnosis can usually be made based on a patient's history and physical examination, but shortly after injury, the diagnosis may be obscured by severe pain and swelling. Magnetic resonance imaging is the imaging modality of choice when the diagnosis remains unclear, and can avoid surgical delays. Early diagnosis and treatment within 3 to 8 weeks after the injury has the advantage of avoiding adhesions and muscle atrophy, and can prevent a delayed return to normal activities. Given the trend toward improved results with early surgical repair of complete rupture, it is important to raise awareness about pectoralis major muscle injury among Emergency Physicians to prevent missed or delayed diagnosis and repair.

Full Text Available Abstract Background Whilst there have been studies on the risks and outcomes of MRSA colonization and infections in HIV-positive patients, local data is limited on the risk factors for MRSA colonization among these patients. We undertook this study in a tertiary HIV care centre to document the risk factors for colonization and to determine the prevalence of MRSA colonization among HIV-positive outpatients in Singapore. Methods This was a cross-sectional study in which factors associated with MRSA positivity among patients with HIV infection were evaluated. A set of standardized questionnaire and data collection forms were available to interview all recruited patients. Following the interview, trained nurses collected swabs from the anterior nares/axilla/groin (NAG, throat and peri-anal regions. Information on demographics, clinical history, laboratory results and hospitalization history were retrieved from medical records. Results MRSA was detected in swab cultures from at least 1 site in 15 patients (5.1%. Inclusion of throat and/or peri-anal swabs increased the sensitivity of NAG screening by 20%. Predictors for MRSA colonization among HIV-positive patients were age, history of pneumonia, lymphoma, presence of a percutaneous device within the past 12 months, history of household members hospitalized more than two times within the past 12 months, and a most recent CD4 count less than 200. Conclusions This study highlights that a proportion of MRSA carriers would have been undetected without multiple-site screening cultures. This study could shed insight into identifying patients at risk of MRSA colonization upon hospital visit and this may suggest that a risk factor-based approach for MRSA surveillance focusing on high risk populations could be considered.

Full Text Available Inflammation is not a disease but a non - specific response of the body defence 1 . Anti - inflammatory drugs have become popular because of their ability in controlling the inflammatory reaction and mitigating the suffering in such clinical situations. Edema represents the early phase of inflammation. 2 In the present study acute and subacute experimental methods were compared with standard drug Indomethacin. R at hind paw edema, formalin induced peritonitis in mice were used as acute methods, paper disc induced granuloma in rats was used as subacute method. Institutional animal ethics committee permission was taken for all the methods as per CPCSEA guide lines. Inflammation was induced by the following 3 methods: i Hind paw edema was produced by sub plantar injection of 0.1ml of1% carrageenin 3 and paw volume was measured by digital plethysmometer at 0, 3hours. ii Intraperitoneal injection of 1.5% formalin 3 was given to albino mice in peritonitis method and ascitic fluid was measured after 6hours by sacrificing the animals. iii Under ether anesthesia, sterilized &weighed paper discs were implanted subcutaneously in each axilla and groin of male wistar rats sutur ed under sterilized conditions in granuloma 4 method. The discs were cleared of extraneous tissue, dried and weighed on the 5 th day by sacrificing the animals. In all the methods 6 animals in each group (test, standard and control were taken. Results were tabulated in each method separately and statistical analysis was done by student t test. P value < 0.05 considered significant. Percentage inhibition in each method was calculated.

Lichen Planus Pigmentosus: The Controversial Consensus

A pigmented variant of lichen planus (LP) was first reported from India in 1974 by Bhutani et al. who coined the term LP pigmentosus (LPP) to give a descriptive nomenclature to it. LP has a number of variants, one of which is LPP. This disease has also later been reported from the Middle East, Latin America, Korea, and Japan, especially in people with darker skin. It has an insidious onset. Initially, small, black or brown macules appear on sun-exposed areas. They later merge to form large hyperpigmented patches. The disease principally affects the sun-exposed areas of the body such as the face, trunk, and upper extremities. The oral mucosa may rarely be involved. However, the palms, soles, and nails are not affected. Histologically, the epidermis is atrophic along with vacuolar degeneration of basal cell layer. The dermis exhibits incontinence of pigment with scattered melanophages and a sparse follicular or perivascular infiltrate. There is a considerable similarity in histopathological findings between LPP and erythema dyschromicum perstans. However, there are immunologic and clinical differences between the two. These observations have led to a controversy regarding the identity of the two entities. While some dermatologists consider them to be the same, others have opined that the two should be considered as distinctly different diseases. A number of associations such as hepatitis C virus infection, frontal fibrosing alopecia, acrokeratosis of Bazex and nephrotic syndrome have been reported with LPP. A rare variant, LPP inversus, with similar clinical and histopathological findings was reported in 2001. As opposed to LPP, this variant occurs in covered intertriginous locations such as groins and axillae and mostly affects white-skinned persons. PMID:27688435

The presence of axillary lymph node metastases is an important prognostic factor in breast cancer. Sentinel lymph node biopsy (SLNB) is an emerging method for the staging of the axilla. It is hoped that with SLNB, the morbidity from axillary lymph node dissection (ALND) can be avoided without compromising the staging and management of early breast cancer. However, only patients found to be SLNB negative benefit from this procedure, as those with positive SLNB may still require ALND. Our objective is to study the various clinico-pathological factors to find predictive factors for axillary lymph node involvement in early breast cancer. It is hoped that with these factors, we will be better able to identify groups of patients most likely to benefit from SLNB. A retrospective study of 380 early breast cancer cases (stage T1 and T2, N0, N1, M0) in women treated in the Department of General Surgery, Tan Tock Seng Hospital, between January 1999 and August 2002, was conducted. Incidence of nodal metastases was correlated with clinico-pathological factors, and analysed by univariate and multivariate analyses. Approximately 35 percent of the 380 cases of early breast cancer had nodal metastases. Multivariate analyses revealed four independent predictors of node positivity: tumour size (p-value equals 0.0001), presence of lymphovascular invasion (p-value is less than 0.0001), tumours with histology other than invasive ductal or lobular carcinoma (p-value equals 0.04), and presence of progesterone receptors (p-value equals 0.05). We have found independent preoperative predictive factors in our local population for the presence of nodal metastases. This information can aid patient selection for SLNB and improve patient counselling.

Since the introduction of nasal endoscopy into the field of Otorhinolaryngology, the treatment paradigm for cases of severe epistaxis has shifted toward early and precise identification of the bleeding site. Although severe epistaxis is usually considered to arise from posterior bleeding, an arterial vascular pedicle in the superior portion of the nasal septum, around the axilla projection of the middle turbinate, posterior to the septal body, frequently has been observed. That vascular pedicle was named the Stamm's S-point. The aim of this study was to describe the S-point and report cases of severe epistaxis originating from it. A retrospective case series study was conducted. Nine patients with spontaneous severe epistaxis, where the S-point was identified as the source of bleeding, were treated between March 2016 and March 2017. Male predominance (77.8%) with age average of 59.3 years old were reported. Most cases presented comorbidities (88.9%) and were not taking acetylsalicylic acid (66.7%). A predominance of left sided involvement (55.6%) and anteroposterior bleeding being the principal initial presentation (77.8%) was seen. Six patients (66.7%) presented with hemoglobin levels below 10g/dL, and four (44.4%) required blood transfusion. Cauterization of S-point was performed in all patients, with complete resolution of bleeding. No patient experienced recurrence of severe epistaxis. The Stamm's S-point, a novel source of spontaneous severe epistaxis, is reported, and its cauterization was effective and safe. Otolaryngologists must actively seek this site of bleeding in cases of severe epistaxis. Copyright © 2018 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Yang, You Jung; Lim, Sung Jig; Song, Jeong Yoon

2010-01-01

To evaluate the potential of Tc-99m diphosphonate as a tracer for sentinel lymph node biopsy in breast cancer. Lymphoscintigraphy of 35 patients (50.9±10.2 years) with breast cancer were acquired after administering a subauroral intradermal injection of Tc-99m diphosphonate 18 h before surgery. Static images were taken within 15 min (early phase) and 15 h after injection (delayed phase). The lymphoscintigraphy identification rate was defined as the percentage of subjects studied with visible foci at axillae. Sentinel lymph node biopsies were performed using a gamma probe and by blue dye injection. Any node that was radioactive or stained with blue dye was labeled as a sentinel lymph node. Lymph nodes without radioactivity or blue dye staining were defined as non sentinel lymph nodes. The intraoperative identification rate was defined as the percentage of patients with a radioactive sentinel lymph node. Percentages of lymphoid cells expressing S-100, CD83, and CD1a were compared. The lymphoscintigraphy identification rate was 94.3% (33/35) during the early phase and 96.9% (31/32) during the delayed phase, whereas the intraoperative identification rate was 94.3% (33/35). The mean percentages of lymphoid cells that stained positively for S-100 or CD83 were lower in sentinel lymph nodes than in non sentinel lymph nodes (1.5% vs. 9.0% for S-100, and 4.5% vs. 9.3% for CD83, respectively, p=0.0286). The mean percentages of lymphoid cells in sentinel lymph nodes and non-sentinel lymph nodes expressing CD1a were 3.3% and 7.0%, respectively (p=ns). Conclusions Tc-99m diphosphonate can reliably detect regional lymph nodes in breast cancer.

This study aimed to determine if there were differences in the imaging features of normal lymph nodes between white and black women using magnetic resonance imaging. Following institutional review board approval, we identified white and black women who underwent breast magnetic resonance imaging from November 1, 2008 to December 31, 2013 at our institution. To identify normal lymph nodes for measurement, patients with any benign or malignant causes for lymph node enlargement and patients with any subsequent breast cancer in the following 2 years were excluded. Black and white women were age matched at a 1:2 ratio. The largest lymph node in each axilla was measured for the long-axis length and maximal cortical thickness. Comparisons were made between white and black women using a conditional logistic regression to control for matching. There were 55 black women and 110 white women for analysis. The mean lymph node long-axis length was 14.7 ± 5.3 mm for black women and 14.4 ± 6.4 mm for white women (P = .678). The mean maximum cortical thickness was 3.3 ± 1.6 mm for black women and 2.6 ± 1.4 mm for Caucasian women (P < .001). A significantly higher percentage of black than white women had cortical thicknesses greater than threshold values of 3, 4, 5, 6, and 7 mm (P < .01 for all). The normal lymph node cortical thickness in black women is significantly greater than in white women, which should be considered when deciding to recommend a lymph node biopsy.

López-Prior, V; Díaz-Expósito, R; Casáns Tormo, I

The aim of this study was to review the feasibility of selective sentinel lymph node biopsy in patients with previous surgery for breast cancer, as well as to examine the factors that may interfere with sentinel node detection. A retrospective review was performed on 91 patients with breast cancer and previous breast surgery, and who underwent sentinel lymph node biopsy. Patients were divided into two groups according to their previous treatment: aesthetic breast surgery in 30 patients (group I) and breast-conserving surgery in 61 (group II). Lymphoscintigraphy was performed after an intra-tumour injection in 21 cases and a peri-areolar injection in 70 cases. An analysis was made of lymphatic drainage patterns and overall sentinel node detection according to clinical, pathological and surgical variables. The overall detection of the sentinel lymph node in the lymphoscintigraphy was 92.3%, with 7.7% of extra-axillary drainages. The identification rate was similar after aesthetic breast surgery (93.3%) and breast-conserving surgery (91.8%). Sentinel lymph nodes were found in the contralateral axilla in two patients (2.2%), and they were included in the histopathology study. The non-identification rate in the lymphoscintigraphy was 7.7%. There was a significantly higher non-detection rate in the highest histological grade tumours (28.6% grade III, 4.5% grade I and 3.6% grade II). Sentinel lymph node biopsy in patients with previous breast surgery is feasible and deserves further studies to assess the influence of different aspects in sentinel node detection in this clinical scenario. A high histological grade was significantly associated with a lower detection. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

Full Text Available Background: For many years the association of skin tags and endocrynopathies has been postulated, although many reports are available but it has never been evaluated to mean normal population. Dyslipidemia is a frequent disorder among people and seemed to be necessary for screening within skin tag condition. This study is designed to find any possible association between skin tags and dyslipidemia. Materials and Methods: From April 2009 to June 2011, 168 patients enrolled the study. Among the remaining 152 patients, there were 89 females (58.5% and 63 males (%41.5. Based on the TLGS study 136 men and 220 women enrolled the control group of study. The mean age was 28.4 years. Patients trained to have normal free diet for at least 1 month then referred to the laboratory. Blood samples were taken over 12 hours fasting with 2 hours intervals. Hypertriglyceridemia was defined as plasma level ≥160 mg/dl for men and ≥130 mg/dl for women. Hypercholesterolemia pointed at its value >200 mg/dl. Normal HDL levels was defined as >39 mg/dl for men and >35 mg/dl to women. Results: Mean skin tag number was 12.6 per subject. The most frequent localizations of skin tags were neck and upper chest (mean number: 13.4, 48.9% followed by axilla (mean number: 11.6, 33% and breast (10.2, 10.1% in the patient group. The mean cholesterol level of case group was 192.2 ± 33.1 mg/dl, while it was 187.0 ± 42 mg/dl in the control group. The mean ± SD for triglyceride was 132.1 ± 69 mg/dl in comparison to 129 ± 74 in the control group. Conclusion: The study showed no significant differences between normal population and patients′ lipid profile.

To prospectively evaluate the feasibility of 3-D radioguided occult lesion localization (iROLL) and to compare iROLL with wire-guided localization (WGL) in patients with early-stage breast cancer undergoing breast-conserving surgery and sentinel lymph node biopsy (SLNB). WGL (standard procedure) and iROLL in combination with SLNB were performed in 31 women (mean age 65.1 ± 11.2 years) with early-stage breast cancer and clinically negative axillae. Patient comfort in respect of both methods was assessed using a ten point scale. SLNB and iROLL were guided by freehand SPECT (fhSPECT). The results of the novel 3-D image-based method were compared with those of WGL, ultrasound-based lesion localization, and histopathology. iROLL successfully detected the malignant primary and at least one sentinel lymph node in 97 % of patients. In a single patient (3 %), only iROLL, and not WGL, enabled lesion localization. The variability between fhSPECT and ultrasound-based depth localization of breast lesions was low (1.2 ± 1.4 mm). Clear margins were achieved in 81 % of the patients; however, precise prediction of clear histopathological surgical margins was not feasible using iROLL. Patients rated iROLL as less painful than WGL with a pain score 0.8 ± 1.2 points (p < 0.01) lower than the score for iROLL. iROLL is a well-tolerated and feasible technique for localizing early-stage breast cancer in the course of breast-conserving surgery, and is a suitable replacement for WGL. As a single image-based procedure for localization of breast lesions and sentinel nodes, iROLL may improve the entire surgical procedure. However, no advantages of the image-guided procedure were found with regard to prediction of complete tumour resection. (orig.)

Purpose To evaluate the influence of race/ethnicity and tumor subtype in pathological complete response (pCR) following treatment with neoadjuvant chemotherapy. Methods 2074 patients diagnosed with breast cancer between 1994 and 2008, treated with neoadjuvant anthracycline- and taxane-based chemotherapy, were included. pCR was defined as no residual invasive cancer in the breast and axilla. Kaplan-Meier product-limit was used to calculate survival outcomes. Cox proportional hazards models were fitted to determine the relationship of patient and tumor variables with outcome. Results Median age was 50 years, 14.6% patients were black, 15.2% Hispanic, 64.3% White, and 5.9% other race. There were no differences in pCR rates among race/ethnicity: (12.3% in black, 14.2% in Hispanics, 12.3% in whites and 11.5% in others, p=.788). Lack of pCR, breast cancer subtype, grade 3 tumors, and lymphovascular invasion were associated with worse RFS and OS (p≤.0001). Differences in RFS by race/ethnicity were seen in the patients with hormone receptor-positive disease, p=.007. In multivariate analysis, Hispanics had improved RFS (HR, 95% CI 0.69; 0.49-0.97) and OS (HR, 95% CI 0.63; 0.41-0.97); blacks had a trend to worse outcomes (RFS:HR, 95% CI 1.28; 0.97-1.68, OS:HR, 1.32; 95% CI; 0.97-1.81) when compared to whites. Conclusions In this cohort of patients, race/ethnicity was not significantly associated with pCR rates. In a multivariate analysis we observed improved outcomes in Hispanics and a trend towards worse outcomes in black patients, when compared to whites. Further research is needed to explore the potential differences in biology and outcomes. PMID:20564153

Full Text Available An 11-year-old male with perinatally acquired human immune deficiency virus (HIV infection on antiretroviral regimen, which included abacavir plus lamivudine (Epzicom, didanosine, ritonavir and atazanavir presented with bilateral axillary striae, increased appetite, fatigue, facial swelling and acute weight gain. Two months prior to presentation, the patient had received a diagnostic and therapeutic intra-articular triamcinolone injection in the knee for pain relief and subsequently became progressively swollen in the face, developed striae bilaterally at the axillae, experienced increased appetite, fatigue and an 8 pound weight gain. During the endocrine workup, suspicion for adrenal insufficiency prompted 24-h urine collection for free cortisol, which was found to be undetectable (below LLQ of 1.0 μg/L. This prompted further evaluation of the hypothalamic–pituitary axis (HPA by standard dose adrenocorticotropic hormone (ACTH stimulation test. A 250 μg cosyntropin stimulation test was performed and confirmed HPA axis suppression. Baseline cortisol level was <1 μg/dL and stimulated cortisol level at 30 min was 3.8 μg/dL. The patient was diagnosed with iatrogenic Cushing syndrome and suppression of HPA axis secondary to the drug interaction between ritonavir (RTV and intra-articular triamcinolone injection. Following endocrine evaluation and workup, the patient was admitted for planned orthopaedic procedure including elective left hamstring lengthening, distal femoral osteotomy and patellar tendon advancement. Taking into consideration the diagnosis of iatrogenic Cushing syndrome, at the start of the surgical procedure, 100 mg IV stress dose of hydrocortisone followed by 50 mg hydrocortisone every 8 h for 24 h was administered. Stress dosing was discontinued 24 h after the procedure. Throughout the hospitalization and upon discharge, the patient continued his ART. From initial presentation, patient has remained clinically stable throughout

The epidemiology of S. aureus depends on conditions in specific populations. Few studies of S. aureus colonization in the older population have been performed in Spain. The aim of this study was to determine the prevalence of methicillin-resistant S. aureus (MRSA) colonization and its molecular epidemiological characteristics in an institutionalized population in community residential care homes in Cadiz, Spain. A cross-sectional epidemiological study was conducted in three residential care homes for older people. Axilla and nostril samples were tested. Identification of S. aureus and antimicrobial susceptibility testing were by MALDI-TOF and MicroScan panels. MRSA strains were subjected to SCCmec typing, multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). The presence of Panton-Valentine leukocidin (PVL) genes was determined by PCR in all S. aureus strains. A total of 293 residents were included. Fifty-one residents (17.4%) were colonized with methicillin-sensitive S. aureus (MSSA) and 11 (3.8%) with MRSA. Resistance to at least two aminoglycosides was observed in 25.4% of MSSA and 90.9% and of MRSA isolates, and resistance to levofloxacin in 80.3% of MSSA and 100% of MRSA isolates. SCCmecIV was detected in all isolates and all except one (ST-125) were ST-8. None of the S. aureus isolates were positive for PVL. A low rate of S. aureus carriage was detected and the prevalence of MRSA was very low. ST8-MRSA-IVc was the dominant clone, and only one strain belonged to ST125-MRSA-IVc. We found MRSA transmission within the residential care homes and a very high rate of quinolone resistance in MSSA and MRSA.

2017-12-01

To describe clinical outcomes of etonogestrel implant patients with migration to the vasculature, chest wall and other distant body sites spontaneously reported to the US Food and Drug Administration Adverse Event Reporting System (FAERS) database. We performed a standardized Medical Dictionary for Regulatory Activities (MedDRA) query in the FAERS database (through November 15, 2015), with reports coded with one or more MedDRA preferred terms that indicate complications with device placement or migration of the device from the original site of insertion to the vasculature, chest wall and other distant body sites. We excluded any cases previously described in the medical literature. We identified 38 cases of pronounced etonogestrel implant migration. Migration locations included the lung/pulmonary artery (n=9), chest wall (n=1), vasculature at locations other than the lung/pulmonary artery (n=14) and extravascular migrations (n=14) to other body sites (e.g., the axilla and clavicle/neck line/shoulder). The majority of cases were asymptomatic and detected when the patient desired implant removal; however, seven cases reported symptoms such as pain, discomfort and dyspnea in association with implant migration. Three cases also describe pulmonary fibrosis and skin reactions as a result of implant migration to the vasculature, chest wall and other distant body sites. Sixteen cases reported surgical removal in an operating room setting. Our FAERS case series demonstrates etonogestrel implant migration to the vasculature, chest wall and other body sites distant from the site of original insertion. As noted by the sponsor in current prescribing information, a key determinant in the risk for etonogestrel contraceptive implant migration appears to be improper insertion technique. Although migration of etonogestrel implants to the vasculature is rare, awareness of migration and education on proper insertion technique may reduce the risk. Published by Elsevier Inc.

To evaluate the ultrasonographic (US) or computer tomography (CT) findings of surgically proven epidermal cysts in the trunk, and to compare the echogenicity of cysts with internal contents. Forty-five patients were retrospectively evaluated. US and CT findings of epidermal cysts were assessed in regard to location, size, shape, number, echogenicity, posterior sound enhancement, internal density, septa, mural nodule and calcification, perilesional infiltration, contrast enhancement, and internal contents. All 45 patients (M:F=29:16; US in 26, CT in 19) had only one cyst, and they were located in the buttocks (n=19), back (n=13), inguinal (n=4), posterior neck (n=3), perineum (n=2), abdominal wall (n=2), presternal (n=1), and axilla (n=1). Of 26 patients who underwent US, there were 8 cases of homogeneously hypoechoic mass (30.8%), 8 of inhomogeneously hypoechoic mass (30.8%), 7 of homogeneously hypoechoic mass with internal hypoechoic lines and echogenic spots (26.9%) and 3 of homogeneously hypoechoic mass with internal echogenic spots (11.5%). Posterior sound enhancement was noted in 21 patients (80.8%). Of 19 patients who underwent CT, there were 14 cases of simple cyst (73.7%) and 5 of abscess-like lesion (26.3%). Overlying skin thickening (n=13), contrast enhancement of cystic wall (n=11), perilesional infiltration (n=7), and internal septa (n=6) were demonstrated. The internal contents of the cysts were keratinous (n=27, 60.0%) or greasy (n=15, 33.3%) material. There was no statistical significance between the echogenicity of the cysts and the internal contents (p > 0.2). Epidermal cysts showed homogeneous or inhomogeneous hypoechoic mass with posterior sound enhancement on US. There was no relationship between the echogenicity of the cysts and the internal contents. In the case of ruptured cyst, an abscess-like lesion with wall enhancement and perilesional infiltration was noted on CT scan

To prospectively evaluate the feasibility of 3-D radioguided occult lesion localization (iROLL) and to compare iROLL with wire-guided localization (WGL) in patients with early-stage breast cancer undergoing breast-conserving surgery and sentinel lymph node biopsy (SLNB). WGL (standard procedure) and iROLL in combination with SLNB were performed in 31 women (mean age 65.1 ± 11.2 years) with early-stage breast cancer and clinically negative axillae. Patient comfort in respect of both methods was assessed using a ten point scale. SLNB and iROLL were guided by freehand SPECT (fhSPECT). The results of the novel 3-D image-based method were compared with those of WGL, ultrasound-based lesion localization, and histopathology. iROLL successfully detected the malignant primary and at least one sentinel lymph node in 97% of patients. In a single patient (3%), only iROLL, and not WGL, enabled lesion localization. The variability between fhSPECT and ultrasound-based depth localization of breast lesions was low (1.2 ± 1.4 mm). Clear margins were achieved in 81% of the patients; however, precise prediction of clear histopathological surgical margins was not feasible using iROLL. Patients rated iROLL as less painful than WGL with a pain score 0.8 ± 1.2 points (p localizing early-stage breast cancer in the course of breast-conserving surgery, and is a suitable replacement for WGL. As a single image-based procedure for localization of breast lesions and sentinel nodes, iROLL may improve the entire surgical procedure. However, no advantages of the image-guided procedure were found with regard to prediction of complete tumour resection.

Full Text Available Background:   Although the majority of soft tissue masses are benign, it is important to consider malignancy in differential diagnoses. Because most soft tissue sarcomas present as a painless mass, clinicians must watch for signs suggestive of malignancy, including large size, rapid growth, and site deep into the deep fascia.The purpose of this study was to determine the relative prevalence according to sex and age, site of tumor, skeletal distribution, and treatment (surgery, chemotherapy and radiotherapy before and after surgery, and ascertain the relative frequency of these tumors in specific anatomic sites and age groups based on pathological studies. Methods: A total of 308 patients, with a musculoskeletal tumor were evaluated retrospectively. All of the patients enrolled into this study were referred to the Beirouni Hospital of Damascus University with a proven diagnosis of alignant soft tissue tumors from the beginning of January 2008 until the end of 2010. The prevalence of the malignant soft tissue tumors in these patients was analyzed. For purposes of analysis, all lesions were placed in 1 of 9 categories: hand and wrist, forearm, humorous (arm, proximal limb girdle (axilla and shoulder, foot and ankle, thigh, hip and buttocks region, trunk, and other lesions. Age and sex also were recorded. Results: Malignant tumors consisted of seven diagnostic categories: malignant fibrous histiocytoma (23%, liposarcoma (22%, rhabdomyosarcoma (9%, leiomyosarcoma (8%, malignant schwannoma (5%, dermatofibrosarcoma protuberans (5%, synovial sarcoma (10%, fibrosarcoma (13%, extraskeletal chondrosarcoma (1%, and extraskeletal Ewing sarcoma (4%. Conclusions: Despite the multitude of pathologic possibilities, most malignant soft-tissue tumors are classified into a small number of diagnoses. These may be further defined when the site of the lesion and the age of the patient are considered. Knowledge of tumor prevalence will assist radiologists in

Laser-based photoepilation of dark skin types demands a delicate combination of appropriate light wavelengths and spot size to achieve optimal epidermal-to-follicular energy absorption ratios. This prospective study assessed the axillary, arm, thigh, and back hair clearing ef cacy of the LightSheer In nity 1060 nm diode laser in 10 Fitzpatrick skin type IV-V patients. Each area was treated up to ve times, at 4-6-week intervals, after which immediate skin responses and adverse events were recorded. Hair count, color and coarseness were assessed before each treatment session, as well as 1, 3, and 6 months following the last session. Both patients and the treating physician rated the degree of improvement with time, and patients also ranked their satisfaction with the treatment outcome. Percent hair reduction from baseline gradually increased with treatment and peaked at 74.6%, 68.4%, and 65.7% for axillary, arm and thigh regions, respectively, 6 months following the last treatment session. Baseline hair growth patterns precluded effective selection of a representative area for hair counting. Patients satisfaction was consistently higher for axillary hair clearance rates, followed by thigh and arm responses. Throughout the follow-up period, the investigator rated 50-67% of the treated axillae as presenting "good" or "very good" hair clearance, and provided similar ratings for 67% of the treated thigh regions at both the 1 and 6 month follow-up sessions. Immediate responses to treatment were mild to moderate and short-lived and no incidents of brosis or scarring were reported. Taken together, the LightSheer In nity 1060 HS Handpiece provided for an ideal ef cacy-safety balance in treating dark-skinned patients, providing for long-term hair clearance with minimal downtime.

Due to the high incidence and prevalence of infection in neonatal ward, especially Neonatal Intensive Care Units (NICUs) reported by different studies and the important role of colonization with hospital germs in the development of nosocomial infections, we intended to evaluate the risk of colonization with hospital germs in neonates and its associated risk factors. This cross-sectional, descriptive-analytical study was conducted in 2016 in a Teaching Center in Iran. In total, 51 neonates were selected based on the inclusion criteria, and after recording their information in a checklist, samples were taken by swab from outer ear, axilla, and groin for culture. Neonates with negative culture from mentioned regions were enrolled in the study. The swab samples again were taken and sent for culture from mentioned regions in at least 3 days after hospitalization. Culture results from first and second sampling were collected and analyzed statistically. This study was conducted on 51 neonates. The mean gestational age among the neonates ranged from 35.25 (Week) ± 2.98. 22 girls (43.1%) and 29 boys (56.9%), most of them were born by cesarean. Based on the results of logistic regression, a significant association was found between the occurrence of colonization of hospital flora and the place hospitalization of the newborns (odds ratio (OR): 4.750; 95% confidence interval (CI): 1.26-17.85). This study revealed that the only risk factors of colonization with hospital flora in neonates are the type of delivery and place of hospitalization. Based on findings of the study, it is recommended to focus on efforts in increasing the rate of natural birth as well as improving conditions of infection control in NICUs to reduce the number of incidences of colonization with hospital flora in neonates.

To investigate whether lymphoscintigraphy and SPECT/CT after intralesional injection of radiopharmaceutical into each tumour separately in patients with multiple malignancies in one breast yields additional sentinel nodes compared to intralesional injection of the largest tumour only. Patients were included prospectively at four centres in The Netherlands. Lymphatic flow was studied using planar lymphoscintigraphy and SPECT/CT until 4 h after administration of {sup 99m}Tc-nanocolloid in the largest tumour. Subsequently, the smaller tumour(s) was injected intratumorally followed by the same imaging sequence. Sentinel nodes were intraoperatively localized using a gamma ray detection probe and vital blue dye. Included in the study were 50 patients. Additional lymphatic drainage was depicted after the second and/or third injection in 32 patients (64 %). Comparison of planar images and SPECT/CT images after consecutive injections enabled visualization of the number and location of additional sentinel nodes (32 axillary, 11 internal mammary chain, 2 intramammary, and 1 interpectoral. A sentinel node contained metastases in 17 patients (34 %)). In five patients with a tumour-positive node in the axilla that was visualized after the first injection, an additional involved axillary node was found after the second injection. In two patients, isolated tumour cells were found in sentinel nodes that were only visualized after the second injection, whilst the sentinel nodes identified after the first injection were tumour-negative. Lymphoscintigraphy and SPECT/CT after consecutive intratumoral injections of tracer enable lymphatic mapping of each tumour separately in patients with multiple malignancies within one breast. The high incidence of additional sentinel nodes draining from tumours other than the largest one suggests that separate tumour-related tracer injections may be a more accurate approach to mapping and sampling of sentinel nodes in patients with multicentric or

Axillary surgery is not considered therapeutic in patients with clinical T1-T2 N0 breast cancer. The importance of axillary staging is eroding in an era in which tumor biology, as defined by biomarker and gene expression profile, is increasingly important in medical decision making. We hypothesized that axillary ultrasound (AUS) is a noninvasive alternative to sentinel lymph node biopsy (SLNB), and AUS could replace SLNB without compromising patient care. Patients with clinical T1-T2 N0 breast cancer and normal AUS were eligible for enrollment. Subjects were randomized to no further axillary staging (arm 1) vs SLNB (arm 2). Descriptive statistics were used to describe the results of the pilot phase of the randomized controlled trial. Sixty-eight subjects were enrolled in the pilot phase of the trial (34 subjects in arm 1, no further staging; 32 subjects in arm 2, SLNB; and 2 subjects voluntarily withdrew from the trial). The median age was 61 years (range 40 to 80 years) in arm 1 and 59 years (range 31 to 81 years) in arm 2, and there were no significant clinical or pathologic differences between the arms. Median follow-up was 17 months (range 1 to 32 months). The negative predictive value (NPV) of AUS for identification of clinically significant axillary disease (>2.0 mm) was 96.9%. No axillary recurrences have been observed in either arm. Successful completion of the pilot phase of the randomized controlled trial confirms the feasibility of the study design, and provides prospective evidence supporting the ability of AUS to exclude clinically significant disease in the axilla. The results provide strong support for a phase 2 randomized controlled trial. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Full Text Available Introduction and Objectives: The brachial plexus is highly variable, in its formation and branching pattern thus, knowledge of its anatomical patterns, may be insufficient for the surgeon operating on or around these nerves or for the regional anesthesiologist working in this area. Therefore, the present study was an attempt to study further about variations of brachial plexus encountered during routine dissection classes. Materials and Methods: The present descriptive study was carried out by dissection of 60 upper limbs of 30 cadavers, in the age group of 18 to 85 years, obtained during a study period of 2 years from the Department of Anatomy. The plexus was studied in its entire course commencing from the formation in cervical region, course through root of the neck and axilla, up to the main terminal branches of the upper extremity. During the dissection, variations of brachial plexus pertaining to its formation from the roots, trunks, divisions and cords and the branching pattern were observed and data was collected. Results: Out of the 60 cadaveric upper limbs studied for the anatomical variations of the brachial plexus, 2 limbs (3.33% were pre-fixed plexuses. Fusion of adjacent trunks was detected in 2 limbs (3.33%. Variations in branches of lateral cord were detected in 8 limbs (13.33%. Among Posterior cord variations 2-thoracodorsal nerves were detected in 2 limbs (3.33%. All the other branches from brachial plexus had been found to have no anatomical variations. Conclusion: In the present study, an attempt has been made to know the possible variations of the brachial plexus. Though the variations mentioned may not alter the normal functioning of the limb of the individual, but knowledge of the variations is of prime importance to be kept in mind, during anaesthetic and surgical procedures.

Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC)-Lyral® is a widely used synthetic fragrance found in personal care and household products. It is an aldehyde, lipophilic enough to penetrate the skin and is a frequent cause of contact sensitization. Describe the frequency of contact allergy to HICC in a Contact Dermatitis Unit, after its inclusion in baseline patch test series. A retrospective study including all patients submitted to patch test, from January 2007 to December 2009. Over a 3-year period, 629 consecutive patients were patch tested. The frequency of positive reactions to HICC was 2.7% (17/629). Of the positive patients, 35% (6/17) gave a history of atopy, 58.8% (10/17) had eczema on the face and neck, 23.5% (4/17) on the hands, 23.5% (4/17) in the axillae, 17.6% (3/17) on the trunk and 6% (3/17) had generalized eczema. All patients were patch positive for more than one allergen: all (17/17) positive to fragrance Mix 2 (FM2); 47% of the patients (8/17) positive to fragrance Mix 1 (FM1); and 23.5% of the patients (4/17) positive to Balsam of Peru. In 94% (16/17) of cases, the reaction was judged to be of current relevance. The frequency of positive reactions to HICC of 2.7% found in our population is according to what is described in several European reports, where HICC is still widely used as a fragrance ingredient. In contrast, in North America, the prevalence is lower. All the patients were positive also to FM2. The association found between reactions to FM1 and HICC is also commonly reported and could represent a concomitant sensitization following increased exposure to fragrance allergens. These data confirm the importance of HICC introduction in the baseline patch test series.

Purpose: To document and explain the current radiotherapeutic management of invasive breast cancer in North America and Europe. We also identified a number of areas of agreement, as well as controversy, toward which additional clinical research should be directed. Methods and materials: An original survey questionnaire was developed to assess radiation oncologists' self-reported management of breast cancer. The questionnaire was administered to physician members of the American Society for Therapeutic Radiology and Oncology and the European Society for Therapeutic Radiology and Oncology. We present the results of the comparative analysis of 702 responses from North America and 435 responses from Europe. Results: Several areas of national and international controversy were identified, including the selection of appropriate candidates for postmastectomy radiation therapy (RT) and the appropriate management of the regional lymph nodes after mastectomy, as well as after lumpectomy. Only 40.7% and 36.1% of respondents would use postmastectomy RT in patients with 1-3 positive lymph nodes in North America and Europe, respectively. Sentinel lymph node biopsy was offered more frequently by North American than European respondents (p < 0.0001) and more frequently by academic than nonacademic respondents in North America (p < 0.05). The average radiation fraction size was larger in Europe than in North America (p < 0.01). European respondents offered RT to the internal mammary chain more often than did the North American respondents (p < 0.001). North American respondents were more likely to offer RT to the supraclavicular fossa (p < 0.001) and axilla (p < 0.01). Conclusion: Marked differences were found in physician opinions regarding the management of breast cancer, with statistically significant international differences in patterns of care. This survey highlighted areas of controversy, providing support for international randomized trials to optimize the RT management of

Core temperature can be accurately measured from the esophagus or nasopharynx during general anesthesia, but neither site is suitable for neuraxial anesthesia. We therefore determined the precision and accuracy of a novel wireless axillary thermometer, the iThermonitor, to determine its suitability for use during neuraxial anesthesia and in other patients who are not intubated. We enrolled 80 adults having upper abdominal surgery with endotracheal intubation. Intraoperative core temperature was measured in distal esophagus and was estimated at the axilla with a wireless iThermonitor WT701 (Raiing Medical, Boston MA) at 5-minute intervals. Pairs of axillary and reference distal esophageal temperatures were compared and summarized using linear regression and repeated-measured Bland-Altman methods. We a priori determined that the iThermonitor would have clinically acceptable accuracy if most estimates were within ±0.5°C of the esophageal reference, and suitable precision if the limits of agreement were within ±0.5°C. There were 3339 sets of paired temperatures. Axillary and esophageal temperatures were similar, with a mean difference (esophageal minus axillary) of only 0.14°C ± 0.26°C (standard deviation). The Bland-Altman 95% limits of agreement were reasonably narrow, with the estimated upper limit at 0.66°C and the lower limit at -0.38°C, thus ±0.52°C, indicating good agreement across the range of mean temperatures from 34.9°C to 38.1°C. The absolute difference was within 0.5°C in 91% of the measurements (95% confidence interval, 88%-93%). Axillary temperature, as recorded by the iThermonitor WT701, well represents core temperature in adults having noncardiac surgery and thus appears suitable for clinical use.

Human parvovirus B19 infection is associated not only with erythema infectiosum (fifth disease) but also, rarely, with purpuric or petechial rashes. Most reports of these atypical rashes describe sporadic cases with skin lesions that have distinctively focal distributions. During a community outbreak of fifth disease, we investigated a cluster of illnesses in children with generalized petechial rashes to determine whether parvovirus was the causative agent and, if so, to describe more fully the clinical spectrum of petechial rashes that are associated with this virus. Systematic evaluation was conducted by general pediatricians of children with petechial rashes for evidence of acute parvovirus infection. During the outbreak, acute parvovirus infection was confirmed in 13 (76%) of 17 children who were evaluated for petechial rash. Confirmed case patients typically had mild constitutional symptoms, and most (11 [85%] of 13) had fever. Petechiae were typically dense and widely distributed; sometimes accentuated in the distal extremities, axillae, or groin; and usually absent from the head/neck. Most case patients had leukopenia, and several had thrombocytopenia. Parvovirus immunoglobulin M was detected in 8 (73%) of 11 acute-phase serum specimens, and immunoglobulin G was detectable only in convalescent specimens. Parvovirus DNA was detected in all 7 tested serum specimens, including 2 acute-phase specimens that were immunoglobulin M-negative. All case patients had brief, uncomplicated illnesses, but 6 were briefly hospitalized and 1 underwent a bone marrow examination. Two case patients developed erythema infectiosum during convalescence. During an outbreak of fifth disease, parvovirus proved to be a common cause of petechial rash in children, and this rash was typically more generalized than described in case reports. Associated clinical features, hematologic abnormalities, and serologic test results are consistent with a viremia-associated illness that is distinct

Accessory breasts have received little attention in the surgical fields, although the condition is quite common in the female population, with 2-6% of women suffering from it. Its convexity and cyclic pain make women feel embarrassed and uncomfortable, so patients often desire surgical excision to improve their appearances and to remove the pain. A total of 967 patients who had been treated by an excision of accessory breast tissue with liposuction using minimal incision from September 2013 to Dec 2015 at the Damsoyu Hospital were analyzed for clinical factors retrospectively. All 967 patients were female. There were 514 (53.2%) unmarried patients and 453 (46.8%) married patients. The major clinical manifestation was the problem in the appearance with cyclic pain in both unmarried and married groups (82.7 vs. 87.9%). Three types of accessory breasts were observed: 779 (80.6%) breast tissue only in axillae, 182 (18.8%) breast tissue with accessory nipple, and 6 (0.6%) breast tissue with accessory nipple-areolar complex. The mean operation time was 58 min. All cyclic axillar pain in our cases was resolved after the operation. Postoperative complications developed in 160 patients (16.55%). Among them, seroma after operation was the most common (11.27%). In our study, 95.65% of the patients were satisfied with the cosmetic outcomes. The surgical excision of accessory breasts with liposuction through the minimal incision is a safe and effective method to make women feel comfortable in clinical manifestations and be satisfied with their cosmetic axillar line.

The novel C-PC/CMC-CD59sp-NPs were made by carbocymethyl chitosan (CMC) loading C-phycocyanin (C-PC) with the lead of CD59 specific ligand peptide (CD59sp) for targeting, and the characteristics and targeted anti-tumor mechanism were explored in order to realize the targeted therapy of C-PC on the growth of HeLa cells both in vitro and vivo . The targeting nanoparticles were synthesized by ionic-gelation method, and the optimal condition was selected out by orthogonal analysis. The properties of nanoparticles were observed by laser particle analyzer and dynamic light scattering (DLS) and Fourier Transform Infrared Spectrometer (FTIR). The effects of nanoparticles on the proliferation of HeLa cells in vitro were assessed by MTT assay. The mice model with tumor was constructed by subcutaneous injection of HeLa cells into the left axilla of NU/NU mice. The weight of tumor and the spleen were tested. The expression quantities of cleaved caspase-3, Bcl-2 were determined by western blot and immunofluorescent staining. Results showed the morphology of the finally prepared nanoparticles was well distributed with a diameter distribution of 200±11.3 nm and zeta potential of -19.5±4.12mV. Under the guidance of CD59sp, the targeting nanoparticles could targetedly and efficiently arrive at the surface of HeLa cells, and had obvious inhibitory effect on HeLa cells proliferation both in vitro and vivo. Moreover, the nanoparticles could induce cell apoptosis by up-regulation of cleaved caspase-3 proteins expression, but down-regulation of Bcl-2 and cyclinD1 proteins. Our study provided a new idea for the research and development of marine drugs, and supplied a theoretical support for the target therapy of anticancer drug.

Full Text Available Background: Skin infections caused by coryneform bacteria are common dermatological conditions. However, to the best of our knowledge, no studies are available on the clinical characteristics and epidemiological features of this group of disorders as one entity from India and abroad. Aims: To study the clinical and epidemiological features of coryneform skin infections Methods: A total of 75 patients presenting with clinically distinctive lesions of pitted keratolysis, erythrasma and trichobacteriosis to our hospital were included in the study. Cases were interviewed with particular emphasis on epidemiological features and the various clinical findings were recorded. Investigations like Gram's stain, Wood's light examination, 10% KOH scrapings, were done in selected cases to ascertain the diagnosis. Results: Pitted keratolysis was more common in the age group of 31-40 years (40% with a male preponderance (76.7%, most commonly affecting pressure bearing areas of the soles with malodour (86.7% and frequent contact with water (58.3% constituting the most important presenting symptom and provocating factor respectively. Erythrasma affected both male and female patients equally and was more commonly detected in patients with a BMI > 23kg/m2 (62.5% and in diabetics (50%. All patients with trichobacteriosis presented with yellow coloured concretions in the axillae. Bromhidrosis (71.4% and failure to regularly use an axillary deodorant (71.4% were the most common presenting symptom and predisposing factor respectively. Conclusion: Coryneform skin infections are common dermatological conditions, though epidemiological data are fragmentary. Hyperhidrosis is a common predisposing factor to all three coryneform skin infections. Asymmetrical distribution of pits has been reported in our study. Diabetic status needs to be evaluated in all patients with erythrasma. Woods lamp examination forms an indispensible tool to diagnose erythrasma and trichobacteriosis.

In this paper, an analysis of the fractionation sensitivity and latency of subcutaneous fibrosis and telangiectasia in a clinical series is presented. The series comprised 163 breast cancer patients who, from 1978 to 1980, received postmastectomy irradiation delivered in 12 fractions, with 2 fractions per week over a period of 37 to 46 days. The total dose was specified either as a maximum absorbed dose of 51.36 Gy, or as a minimum target dose of 36.6 Gy specified at the level of the mid-axilla. from 1981 to 1982, 66 patients received a minimum target dose of 40.92 Gy in 22 fractions administered as 5 fractions per week over 29 to 35 days. Late complications were evaluated prospectively at a single follow-up after a minimum observation time of 16 months. The clinical endpoints analyzed were subcutaneous fibrosis and telangiectasia. The data were analyzed using a mixture model that incorporates both dose fractionation and latency effects. The length of time to expression of 90% of the ultimate frequency of moderate or severe complications was 3.2 years (95% confidence limits (c.l.) [2.3,3.9] years) and 4.7 years (95% c.l. [4.0,.8] years) for fibrosis and telangiectasia respectively, while the α/β ratios were 1.9 Gy (95% c.l. [0.8,3.0] Gy) and 3.7 Gy (95% c.l. [0.2,47] Gy), respectively. For subcutaneous fibrosis the time to reach a specific grade of reaction increases with the grade, thus being consistent with the clinical impression that fibrosis proresses in severity over time. If latency and censoring effects are unaccounted for, serious underestimates of the ultimate frequency of radiation complications in groups with incomplete follow-up may result.

Full Text Available Background:The etiology of skin tags (STs is not fully understood. A relation to diabetes mellitus and obesity was suggested. Few studies of possible mast cells (MCs involvement were reported. Tyrptase is a mast cell mediator and a potent fibroblast growth factor. It may provide a molecular link between mast cell activation and fibrosis. Aims: The aim was to assess clinical and laboratory findings in patients with STs, and the possible link between obesity, dyslipidemia, and lesional MC count/tryptase expression. Materials and Methods: A total of 20 patients with STs were subjected to clinical examination, estimation of body mass index (BMI, fasting blood glucose (FBG, postprandial blood glucose (PPBG, serum cholesterol and triglycerides, abdominal ultrasound for fatty liver assessment, in addition to study of MCs through staining for MC tryptase in two skin biopsies; lesional and nonlesional (control. Results:All patients showed abnormally high BMI and hypertriglyceridemia, with abnormal sonographic pattern in 15 patients (75%. STs number positively correlated with the age of patients. STs showed significantly higher MC counts and tryptase expression, compared with control skin ( P < 0.001, with no correlation of the STs number or MC count with BMI, FBG, PPBG or serum cholesterol. Obese patients showed a significantly higher MC count than overweight and there was a positive correlation between MC count and serum triglycerides. Axilla and under breast STs showed a higher MC count compared with other sites. Conclusions:STs seem to be related to obesity and hypertriglyceridemia. MCs with their tryptase are possibly involved in pathogenesis of STs. MC count is related to the associated factors; obesity and serum triglycerides. MC tryptase expression is a reliable method for accurate tissue MC counting.

contribution from the contralateral breast, a lead shield was placed between the two mammary glands. A SPET with the patient in the supine position was also performed in 16 subjects. A quantitative analysis evaluating both breasts and lymph node was performed. All breast lesions were verified after surgery and/or fine needle aspiration. A ratio higher than 1.4 and 2.0 between the uptake and the normal tissue was considered positive for malignancy in the breast and the axilla respectively. Twenty-eight patients had breast cancer (size mean 4-38 mm) and 11 had one ore more metastatic lymph nodes in the axilla (micrometastases in 3 subjects). Our study revealed an increased uptake of radiotracer in 23 out of 28 patient with effective breast cancer; the smallest lesion observed was 7 mm nodule. The sensitivity of the method was 82% (96% considering lesions more than 12 mm). 1 false-positive result was observed in 18 patients with benign disease (9 proliferative fibrocystic dysplasia, 5 fibroadenoma, 2 fibrocystic dysplasia, 1 post-surgical fibrosis, 1 granulomatosis. At scintimammography, axillary uptake of 99mTc-TF was observed in 5 subjects with lymph node metastasis, with 6 false-negative cases. Three false-negative occurred: 1 in a patient without detection of neoplastic disease of breast and 2 in patient suffering of breast cancer but not axillary metastasis. The sensitivity in the axillary lymph nodes detection was 45% and the specificity 95%. The low rate sensitivity is affected by the number of patients with micro metastatic axillary disease. In our experience the following SPET acquisition did not modified the sensitivity of examination. On the other hand, Schillaci (EANM 2002) demonstrated SPET-TC was able to provide further information of clinical value in 40% of the studies. Scintimammography showed high sensitivity and specificity for the detection of palpable breast cancer. Specificity was clearly higher in comparison with other diagnostic imaging procedures. The

Purpose: We present the initial findings of our in-house protocol treating the tumor bed alone after lumpectomy with low dose rate (LDR) interstitial brachytherapy in selected patients with early stage breast cancer treated with breast conserving therapy (BCT). Materials and Methods: Since 1/1/93, 50 women with early stage breast cancer were entered into a protocol of tumor bed irradiation alone using an interstitial LDR implant. Patients were eligible if their tumor was an infiltrating ductal carcinoma ≤ 3 cm in maximum diameter, pathologic margins were clear by at least 2 mm, the tumor did not contain an extensive intraductal component, the axilla was surgically staged with ≤ 3 nodes involved with cancer, and a postoperative mammogram was performed. Implants were positioned using a template guide delivering 50 Gy over 96 hours to the lumpectomy bed plus a 1-2 cm margin. Local control, cosmetic outcome, and complications were assessed. Results: Patients ranged in age from 40 to 84 years (median 65). The median tumor size was 10 mm (range, 1-25). Seventeen patients (34%) had well differentiated tumors, 22 (4%) had moderately differentiated tumors, and in 11 (22%) the tumor was poorly differentiated. Forty-five patients (90%) were node negative while 5 (10%) had 1-3 positive nodes. A total of 23 (46%) patients were placed on tamoxifen and 3 (6%) received adjuvant systemic chemotherapy. No patient was lost to follow-up. The median follow-up is 40 months (range 29-50). No patient has experienced a local, regional, or distant failure. One patient died from colorectal carcinoma with no evidence of recurrent breast cancer. Good-to-excellent cosmetic results have been observed in all 50 patients (median cosmetic follow-up 36 months). No patient has experienced significant sequelae related to their implant. Conclusions: Early results with treatment of the tumor bed alone with a LDR interstitial implant appear promising. Long-term follow-up of these patients will be

Purpose: Deodorant use during radiation therapy for breast cancer has been controversial as there are concerns deodorant use may exacerbate axillary skin toxicity. The present study prospectively determined the use of both aluminum-containing and non aluminum containing deodorants on axillary skin toxicity during conventionally fractionated postoperative radiation therapy for breast cancer. Methods and Materials: This 3-arm randomized controlled study was conducted at a single center, tertiary cancer hospital between March 2011 and April 2013. Participants were randomized to 1 of 2 experimental groups (aluminum-containing deodorant and soap or non–aluminum containing deodorant and soap) or a control group (soap). A total of 333 participants were randomized. Generalized estimating equations were used to estimate and compare the odds of experiencing high levels of sweating and skin toxicity in each of the deodorant groups to the odds in the control group. The study evaluated a range of endpoints including objective measurements of axilla sweating, skin toxicity, pain, itch and burning. Quality of life was assessed with a validated questionnaire. Results: Radiation characteristics were similar across all groups. Patients in the deodorant groups did not report significantly different ratings for axillary pain, itch, or burning compared with the control group. Patients in the aluminum-containing deodorant group experienced significantly less sweating than the control; the odds of their sweating being barely tolerable and frequently or always interfering with their daily activities was decreased by 85% (odds ratio, 0.15; 95% confidence interval, 0.03-0.91). Conclusions: We found no evidence that the use of either aluminum-containing or non–aluminum containing deodorant adversely effects axillary skin reaction during conventionally fractionated radiation therapy for breast cancer. Our analysis also suggests patients in the aluminum-containing deodorant arm had

1. The geographic range of Carcinonemertes epialti has been greatly extended. The worms are found from Bahia San Quintin, Baja California, Mexico, to Page's Lagoon, Vancouver Island, British Columbia, Canada. 2. New host records for C. epialti include H. oregonensis, and H. nudus. It is rare on its type host Pugettia producta. Specimens of Carcinonemertes of uncertain affinities are also found on Cancer antennarius, C. anthonyi and C. productus. 3. Carcinonemertes epialti adults are egg predators on ovigerous hosts. Growth, demography and abundance are described in relation to the embryogenic stage of the host brood at Bodega Harbor, California. 4. Nonfeeding juveniles are ensheathed on individuals of both host sexes over 8.0 mm carapace width. 5. Transmission experiments show that contact transfer of juvenile nemerteans from males to other hosts may occur. 6. The percentage of infestation and mean density peak in autumn on H. oregonensis at Bodega Harbor. 7. Ovigerous female hosts are more frequently infested with C. epialti, particularly at small host sizes, than are male or nonovigerous female hosts at Bodega Harbor. However, average worm density on ovigerous females is low. 8. Mean density of C. epialti rises through late postmolt, declines during intermolt and rebuilds to a high level in late premolt H. oregonensisfrom Bodega Harbor. 9. Large crabs have a higher percentage of infestations and mean densities per infection than do small crabs. Nemerteans are more frequently found in the sternal-abdominal furrow and less frequently in the limb axillae on large crabs. 10. A model of C. epialti transmission and site occupancy is proposed, incorporating the influence of host size, sex, reproductive state, embryogenesis, molt cycle stage and molt cycle duration of H. oregonensis at Bodega Harbor. Site availability increases with host size. At higher densities the juvenile nemerteans increasingly occupy less preferred sites. Transferral of juvenile nemerteans occurs

Purpose: This case series study evaluated the feasibility and effectiveness of an interstitial high-dose rate brachytherapy (HDR-BT) procedure combined with an at-risk organ-sparing procedure. Methods and Materials: Thirty patients who were scheduled for reirradiation treatment for recurrent cancer after receiving a median dose of 60 Gy (range, 44-70 Gy) in 2-Gy fractions of previous external beam treatment were enrolled. Thirteen patients had lesions in the head and neck, and other lesions were located in the axilla, skeleton, breast, pelvis, and abdominal wall. Chief complaints included local masses (for 25) and refractory pain (for 21). After high-dose rate brachytherapy applicator needle implantation, an optimal CT-based three-dimensional brachytherapy plan was created with a virtual at-risk organ shift from the target. According to the plan, hyaluronic acid gel was injected to maintain the shift during irradiation. The prescribed dose was the result of an individualized tradeoff between target dose and at-risk organ dose, to avoid serious complications. A single-fraction dose of 18.0 Gy (median, equivalent to 75.6 Gy at an α/β value of 3; range, 16-20 Gy) was applied to the tumor. Results: The at-risk organ dose decreased from 9.1 ± 0.9 Gy to 4.4 ± 0.4 Gy (mean ± standard deviation, p < 0.01), and the normal tissue complication probability decreased from 60.8% ± 12.6% to 16.1% ± 19.8% (p < 0.01). The shift effect lasted at least 4 hours and disappeared gradually. Distinct tumor shrinkage in 20 of 21 eligible patients, including tumor disappearance in 6 patients, pain reduction in 18 of 21 eligible patients, and no unexpected late toxicity greater than grade 2 were observed during the 19.5-month observation period. Conclusions: This at-risk organ-sparing preservation procedure may provide a safe and efficient reirradiation treatment.

Full Text Available PURPOSE: Radiation therapy (RT is commonly used as definitive treatment for early-stage nodular lymphocyte-predominant Hodgkin's lymphoma (NLPHL. We evaluated the cause-specific survival (CSS, overall survival (OS, and second malignancy (SM rates in patients with early-stage NLPHL treated with RT. METHODS AND MATERIALS: Patients with stage I-II NLPHL between 1988 and 2009 who underwent RT were selected from the Surveillance, Epidemiology and End Results database. Univariate analysis (UVA for CSS and Os was performed using the Kaplan-Meier method and included age, gender, involved site, year of diagnosis, presence of B-symptoms, and extranodal involvement (ENI. Multivariable analysis (MVA was performed using Cox Proportional Hazards modeling and included the above clinical variables. SM were classified as RT-related or non-RT-related. Freedom from SM and freedom from RT-related SM were determined using the Kaplan-Meier method. RESULTS: The study cohort included 469 patients. Median age was 37 years. The most common involved sites were the head and neck (36%, axilla/arm (26%, and multiple lymph node regions (18%. Sixty-eight percent had stage I disease, 70% were male, 4% had ENI, and 7% had B-symptoms. Median follow-up was 6 years. Ten-year CSS and Os were 98% and 88%, respectively. On UVA, none of the covariates was associated with CSS. Increasing age (p<0.01 and female gender (p<0.01 were associated with worse Os. On MVA, older age (p<0.01, female gender (p=0.04, multiple regions of involvement (p=0.03, stage I disease (p=0.02, and presence of B-symptoms (p=0.02 were associated with worse Os. Ten-year freedom from SM and freedom from RT-related SM were 89% and 99%, respectively. CONCLUSIONS: This is the largest series to evaluate the outcomes of stage I-II NLPHL patients treated with RT and found that this patient population has an excellent long-term prognosis and a low rate of RT-related second malignancies.

Purpose: There is an increased incidence of breast cancer following mantle field radiation therapy for Hodgkin's disease (HD). We reviewed the experience at the Mallinckrodt Institute of Radiology (MIR) for radiation factors related to the development of breast cancer after mantle field radiation therapy for HD. Methods: The radiation therapy records of 152 women treated with mantle field irradiation for HD at MIR between 1966-1985 were reviewed for the development of breast cancer and treatment-related factors. All patients had a minimum of 5 years of follow-up. The treatment era (1966-1974 vs. 1975-1985), stage of HD, mediastinal dose, axillary dose, maximum dose from the anterior field (anterior d max dose), the anterior-posterior:posterior-anterior (AP:PA) ratio, age at the time of treatment, length of follow-up, and history of splenectomy were analyzed as possible contributing factors for the development of breast cancer. The observed number of breast cancers was compared to the expected number based on age-adjusted incidences from the Connecticut Tumor Registry. Results: Ten breast cancers occurred in the population. Eight involved an upper outer quadrant. In a multivariate analysis, the development of breast cancer was significantly associated with axillary dose. Patients in the early treatment era were at an increased risk for the development of breast cancer due to high anterior d max and breast doses from weighting the fields anteriorly on a low energy linear accelerator. The use of current radiation therapy techniques was not related to an increased risk of breast cancer with a median follow-up of 13 years. Conclusions: A high dose to the axilla and the anterior d max point is significantly associated with the development of breast cancer after mantle field irradiation for HD. Efforts to protect the breast from high doses will likely lessen the increased risk of breast cancer in women treated with radiation therapy for HD

Pain is one of the most commonly reported breast complaints. Referred pain from inflammation of the shoulder bursa is often overlooked as a cause of breast pain. The objective of this study is to evaluate the role of shoulder bursitis as a cause of breast/chest pain. An IRB-approved retrospective review from July 2005 to September 2009 identified 461 patients presenting with breast/chest pain. Cases identified with a trigger point in the medial aspect of the ipsilateral scapula were treated with a bursitis injection at the point of maximum tenderness. The bursitis injection contains a mixture of local anesthetic and corticosteroid. Presenting complaint, clinical response and associated factors were recorded and treated with descriptive statistics. Average age of the study group was 53.4 ± 12.7 years, and average BMI was 30.4 ± 7.4. One hundred and three patients were diagnosed with shoulder bursitis as the cause of breast pain and received the bursitis injection. Most cases (81/103 or 78.6%) presented with the breast/chest as the site of most significant discomfort, where 8.7% (9/103) had the most severe pain at the shoulder, 3.9% (4/103) at the axilla and 3.9% (4/103) at the medial scapular border. Of the treated patients, 83.5% (86/103) had complete relief of the pain, 12.6% (13/103) had improvement of symptoms with some degree of residual pain, and only 3.9%(4/103) did not respond at all to the treatment. The most commonly associated factor to the diagnosis of bursitis was the history of a previous mastectomy, present in 27.2% (28/103) of the cases. Shoulder bursitis represents a significant cause of breast/chest pain (22.3% or 103/461) and can be successfully treated with a local injection at site of maximum tenderness in the medial scapular border.

Full Text Available Abstract Background Although sentinel lymph node (SLN biopsy is a standard of care for the evaluation of the axillary lymph nodes during breast cancer surgery, a substantial degree of variation exists among individual surgeons as to what represents an adequate assessment. The aim of the current study was to assess when metastatic disease was first identified within consecutively harvested SLN candidates for invasive breast cancers demonstrating a positive SLN. Methods We retrospectively analyzed a series of 400 breast cancers from a recently published prospective randomized clinical trial. A combined radiocolloid and blue dye technique was used. All potential SLN candidates, containing counts of at least 10% of the hottest SLN and/or containing blue dye, were harvested and were consecutively numbered in the order of the decreasing level of counts (with the hottest SLN representing SLN #1. Results Among 371 invasive breast cancers, a SLN was identified within 353 cases (95%. Mean number of SLNs identified was 2.5 (range, 1 to 9, with a single SLN identified in 104 (29% cases, two identified in 110 (31%, three identified in 73 (21%, four identified in 35 (10%, five identified in 16 (5%, and six or more identified in 15 (4%. A positive SLN was found in 104 (29% cases. SLN #1 was the first positive SLN in 86 (83%. SLN #2 was the first positive SLN in 15 (14%. SLN #3, SLN #4, and SLN #5 were the first positive SLN in one case (1% each. A positive SLN was found in 18% (19/104 of cases when a single SLN was identified, as compared to in 34% (85/249 when two or more SLNs were identified (P = 0.003. Conclusion The accurate and optimal assessment of the axilla during breast cancer surgery requires persistence and diligence for attempting to identify all potential SLN candidates in order to avoid failing to recognize a positive SLN. The scenario in which only a single negative SLN candidate is intraoperatively identified is one that should raise some

Full Text Available Abstract Background Sentinel lymph node (SLN biopsy is the standard of care for the surgical assessment of the axilla during breast cancer surgery. However, the diagnostic accuracy of intraoperative frozen section analysis for confirming metastatic involvement of SLNs in cases of invasive lobular carcinoma (ILC versus that of invasive ductal carcinoma (IDC has generated controversy secondary to a frequently low-grade cytologic appearance and an often discohesive pattern displayed by metastatic lymph nodes in ILC. In the current report, we present a comparison of intraoperative frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Methods We evaluated the results of 131 consecutive cases of ILC from 1997 to 2008 and 133 cases of IDC (selected by a random sequence generator program from amongst 1163 consecutive cases of IDC from the same time period. All cases had at least one SLN that had both intraoperative frozen section analysis and confirmatory permanent section analysis performed. Results No statistically significant difference was found in the sensitivity (67% vs. 75%, P = 0.385, specificity (100% vs. 100%, accuracy (86% vs. 92%, P = 0.172, false negative rate (33% vs. 25%, P = 0.385, negative predictive value (81% vs. 89%, P = 0.158, and positive predictive value (100% vs. 100% for frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Conclusion Since there was no statistically significant difference in sensitivity, specificity, accuracy, false negative rate, negative predictive value, and positive predictive value between frozen section analysis of SLNs for patients with ILC and IDC, the clinical accuracy of confirming metastatic involvement of SLNs on frozen section analysis for ILC should not be considered inferior to the clinical accuracy for IDC. Therefore, frozen section analysis

In early-stage classical Hodgkin lymphoma (HL) the target volume nowadays consists of the volume of the originally involved nodes. Delineation of this volume on a post-chemotherapy CT-scan is challenging. We report on the interobserver variability in target volume definition and its impact on resulting treatment plans. Two representative cases were selected (1: male, stage IB, localization: left axilla; 2: female, stage IIB, localizations: mediastinum and bilateral neck). Eight experienced observers individually defined the clinical target volume (CTV) using involved-node radiotherapy (INRT) as defined by the EORTC-GELA guidelines for the H10 trial. A consensus contour was generated and the standard deviation computed. We investigated the overlap between observer and consensus contour [Sørensen-Dice coefficient (DSC)] and the magnitude of gross deviations between the surfaces of the observer and consensus contour (Hausdorff distance). 3D-conformal (3D-CRT) and intensity-modulated radiotherapy (IMRT) plans were calculated for each contour in order to investigate the impact of interobserver variability on each treatment modality. Similar target coverage was enforced for all plans. The median CTV was 120 cm 3 (IQR: 95-173 cm 3 ) for Case 1, and 255 cm 3 (IQR: 183-293 cm 3 ) for Case 2. DSC values were generally high (>0.7), and Hausdorff distances were about 30 mm. The SDs between all observer contours, providing an estimate of the systematic error associated with delineation uncertainty, ranged from 1.9 to 3.8 mm (median: 3.2 mm). Variations in mean dose resulting from different observer contours were small and were not higher in IMRT plans than in 3D-CRT plans. We observed considerable differences in target volume delineation, but the systematic delineation uncertainty of around 3 mm is comparable to that reported in other tumour sites. This report is a first step towards calculating an evidence-based planning target volume margin for INRT in HL.

To compare the results of patients with locally advanced breast cancer receiving two different regimens Fluorouracil, Doxorubicin and Cyclophosphamide (FAC) and Paclitaxel and Carboplatin. Study Design: Comparative study. Place and Duration of Study: The Oncology Department, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from March 2007 to September 2008. Methodology: Patients with inoperable locally advanced breast cancer of stage were included. Sixteen patients were given FAC regimen and 9 patients were given Paclitaxel and Carboplatin, each combination was cycled after 21 days for four times. Before enrollment, detailed medical histories, physical examinations and performance status assessments were done as well as post chemotherapy evaluation with regular follow-up visits was done. Complete Response (CR, 100%) is defined as the disappearance of all known disease parameter i.e. disappearance in detectable tumour size, node free disease and surgery is possible. Paratial Response (PR, > 50%) was defined by 50% or greater decrease in the sum of the areas of bidimensionally measured lesions i.e. change of N2 to N1 or no status and some surgical procedure is possible to down stage the disease. Minor Response (MR) was defined as a decrease in the tumour insufficient to quality for partial resp once. Static disease or no evaluable reflected no significant change in disease and no evidence of new disease. Progression of disease (> 25%) was defined as a 25% or greater increase in the area of any lesion > 2 cm or in the sum of the products of the individual lesions or the appearance of new malignant lesions, surgery not possible. Results: Twenty five patients completed neoadjuvant chemotherapy. Sixteen (66%) patients received FAC and 9 (37%) patients received PC chemotherapy. Overall CR (breast and axilla) was 54%, PR was 16% and minor response (MR) was 8%. FAC treatment induced more emesis, mucositis, alopecia and cardiotoxicity. No death occurred

Full text: The treatment of moist skin desquamation (ulceration) following radiation therapy focuses on promoting healing, preventing microbial infections, protecting from mechanical trauma and providing pain relief. Various dressings like hydrocolloid, 1% gentian violet and other topical applications are routinely used. This study evaluated the use of freeze-dried, irradiated amnion from the Tata Memorial Hospital Tissue Bank in the management of radiation ulcers from 2001 to 2007. During this period, 2095 amnion dressings were used in 554 patients (238 male and 316 female). The ulcer was cleaned with normal saline and the amnion applied directly on the affected area. No topical antibiotics were used. The ulcer sites were in the regions of the groin and perianal area (40.79%), head and neck (30.50%), breast and axilla (18.59%), limbs (5.78%), chest (2.70%) and back (1.62%). Healing occurred within 4 days to 14 days using a single application of amnion in 291 patients (52.53%), 2 dressings in 129 patients (23.28%) and 3 dressings in 74 patients (13.36%). The remaining 60 patients (10.83%) required four or more dressings which were used over a period of a month. The amnion dressing was found to be convenient to apply and adhered well to the affected areas without the use of any adhesives unlike with routine hydro-colloid dressing. This was particularly advantageous in sites with irregular contours such as the groin and perianal areas and the head and neck regions (71.29%). Patients experienced almost immediate pain relief and the need for analgesics was reduced. In the majority of patients healing occurred earlier than was usually obtained with routine dressings. The amnion dressing proved to be advantageous over co ventional dressings because of its convenience of use and cost effectiveness due to shorter duration of healing, fewer dressing changes and diminished use of analgesics and antibiotics.

Sentinel lymph node (SLN) biopsy is a reliable technique for determining axillary status in patients with early breast cancer. This technique is a minimally invasive procedure that can avoid the use of lymphadenectomy in patients without axillary involvement. We present a validation study of SLN biopsy with subareolar injection of 99mTc-nanocolloids. We studied 100 patients with early breast cancer (T1 and T2) over a 2-year period. All patients underwent deep subareolar-injection of 99mTc-nanocoloid for localization of the sentinel node. Images were obtained and when the sentinel node was seen, it was marked on the skin. All patients underwent tumor excision and radioguided SLN biopsy followed by complete lymphadenectomy. Histopathological analysis of sentinel nodes was performed by hematoxylin-eosin and immunohistochemistry with cytokeratins. The sentinel node was identified in all patients, and a mean of 1.95 sentinel nodes per patient were found. Lymphatic metastases in the sentinel node were found in 44 patients and in 15 of these tumoral spread was also found in the remaining axillary nodes. In the 56 remaining patients the sentinel node was free of metastasis, but in two of them a non-sentinel node was found to be positive (4.5% false negative rate). Sensitivity was 95.7% (44/46), specificity was 100% (54/54), the positive predictive value was 100% and the negative predictive value was 96.4% (54/56). SLN biopsy is an accurate alternative to complete axillary lymph node dissection in patients with early-stage breast cancer. This technique improves the staging of these patients and decreases the morbidity associated with lymphadenectomy. The advantages of subareolar injection are that a single injection site is required, the tumor does not have to be located by other techniques, it allows rapid visualization of the sentinel node and avoids the "shine through phenomenon" when the tumor is located near the axilla.

Several studies have reported a high risk of local disease recurrence (LR) and locoregional disease recurrence (LRR) in patients with breast cancer after neoadjuvant chemotherapy (NCT) and breast-conserving therapy (BCT). The objective of the current study was to identify potential risk factors for LR and LRR after NCT and BCT. Individual patient data sets from 9 studies were pooled. The outcomes of interest were the occurrence of LR and/or LRR. A 1-stage meta-analytic approach was used. Cox proportional hazards regression models were applied to identify factors that were predictive of LR and LRR, respectively. A total of 9 studies (4125 patients) provided their data sets. The 10-year LR rate was 6.5%, whereas the 10-year LRR rate was 10.3%. Four factors were found to be associated with a higher risk of LR: 1) estrogen receptor-negative disease; 2) cN + disease; 3) a lack of pathologic complete response in axilla (pN0); and 4) pN2 to pN3 disease. The predictive score for LR determined 3 risk groups: a low-risk, intermediate-risk, and high-risk group with 10-year LR rates of 4.0%, 7.9%, and 20.4%, respectively. Two additional factors were found to be associated with an increased risk of LRR: cT3 to cT4 disease and a lack of pathologic complete response in the breast. The predictive score for LRR determined 3 risk groups; a low-risk, intermediate-risk, and high-risk group with 10-year LRR rates of 3.2%, 10.1%, and 24.1%, respectively. BCT after NCT appears to be an oncologically safe procedure for a large percentage of patients with breast cancer. Two easy-to-use clinical scores were developed that can help clinicians to identify patients at higher risk of LR and LRR after NCT and BCT and individualize the postoperative treatment plan and follow-up.

Full Text Available History of present illness: A 26-year-old male presented to the emergency department with a burning rash over his left axilla and chest that started 2 days prior to presentation. The pain had been steadily worsening and was exacerbated by touch and the rubbing of his clothes over it. Patient denied fevers, chills, or weakness. Patient denied any past medical history, past surgical history or medications. He was unsure of his vaccination history and endorsed having chicken pox as a child. Significant findings: The patient was in mild distress, afebrile, with stable vital signs. His physical exam revealed an erythematous, grouped vesicular rash in various stages of progression including erythematous papules, clear vesicles, and pustular vesicles. Few lesions were scabbed over. No signs of crusting or scarring were appreciated. The distribution encompassed the entire left T4 dermatome both posteriorly and anteriorly. No other rashes were appreciated elsewhere on the body. Discussion: Herpes Zoster (HZ, also known as “shingles,” is a result of the reactivation Varicella Zoster Virus (VZV that emerges from latency in the sensory dorsal root ganglion. The reactivation causes the spreading of a classic rash of group vesicular lesions in various stages along the unilateral sensory dermatomal distribution over the first 3 days. Ulceration and crusting begin to occur after 3-5 days.1 The diagnosis is usually made clinically; however PCR testing of skin lesions is also available to differentiate between VZV, HSV1, and HSV2.2 The incidence of HZ increases with age due to immunosenesacence of cell mediated immunity, with the mean age between 43 and 53 years old.3 An immunocompromised state, due to factors like human immunodeficiency virus (HIV, medications, and autoimmune disease, also increases the incidence of HZ.4-6 A routine HIV screening in this patient was negative. He was prescribed oral acyclovir 800 mg, five times per day for five days.

Systemic contact dermatitis is a condition that occurs when an individual sensitized to a contact allergen is exposed to that same allergen or a cross-reacting molecule through a systemic route. Systemic exposure to allergens can include transcutaneous, transmucosal, oral, intravenous, intramuscular, and inhalational routes. Baboon syndrome is perhaps the most recognizable form of systemic contact dermatitis, presenting with diffuse, well demarcated erythema of the buttocks, upper inner thighs, and axillae. Other forms of systemic contact dermatitis include dermatitis at sites of previous exposure to the allergen such as at a previous site of dermatitis or at sites of previous positive patch tests, dyshidrotic hand eczema, flexural dermatitis, exanthematous rash, erythroderma, and vasculitis-like lesions. The most common causes of systemic contact dermatitis consist of three groups of allergens: (i) metals including mercury, nickel, and gold; (ii) medications including aminoglycoside antibacterials, corticosteroids, and aminophylline; and (iii) plants and herbal products including the Compositae and Anacardiaceae plant families and Balsam of Peru. Baboon syndrome caused by systemic medications without a known history of previous cutaneous sensitization in the patient has been termed drug-related baboon syndrome (DRBS) or symmetric drug-related intertriginous and flexural exanthema (SDRIFE). Criteria for SDRIFE include exposure to systemic drug at first or repeated dose, erythema of the gluteal/perianal area and/or V-shaped erythema of the inguinal area, involvement of at least one other intertriginous localization, symmetry of affected areas, and absence of systemic toxicity. The most common causes are aminopenicillins, β-lactam antibacterials, and certain chemotherapeutic agents, though the list of etiologic agents continues to grow. Baboon syndrome and SDRIFE should be strongly considered in a patient presenting with a symmetric intertriginous eruption involving

Medical records were screened, and photographs and videos were assessed to note the details of various ostial parameters. The major time points in evaluation were 4 weeks, 6 weeks, 3 months, and 6 months post-DCR. The ostia were defined and parameters like shape, size, location, and evolution of ostium were noted. Evaluation parameters were defined for internal common opening (ICO, ostium stents, and ostium granulomas. Ostium cicatrix and synechiae were graded based on their significance. Surgical success rates were computed and ostium characteristics in failed cases were studied.Results: A total of 125 ostia were evaluated on the aforementioned ostium parameters. Because five ostia showed a complete cicatricial closure with no recognizable features, the remaining 120 ostia were studied. The ostium location was anterior to the axilla of middle turbinate in 85.8% (103/120 of the cases. Moreover, 76.6% (92/120 of the ostia were circular to oval in shape, with a shallow base. The ostium size was >8×5 mm in 78.3% (94/120 of the cases. The ICO was found to be located in the central or paracentral basal area in 75.8% (91/120. The anatomical and functional success rates achieved were 96% and 93.6%, respectively. All the five cases with anatomical failures showed a complete cicatrization and the ICO movements were poor in all the three cases of functional failure.Conclusion: The article attempts to standardize the postoperative

Full Text Available Abstract Background As a result of the recent international vigilance regarding disease assessment, accurate measurement of body temperature has become increasingly important. Yet, trusted low-tech, portable mercury glass thermometers are no longer available. Thus, comparing accuracy of mercury-free thermometers with mercury devices is essential. Study purposes were 1 to examine age, race, site as variables affecting temperature measurement in adults, and 2 to compare clinical accuracy of low-tech Galinstan-in-glass device to mercury-in-glass at oral, axillary, groin, and rectal sites in adults. Methods Setting 176 bed accredited healthcare facility, rural northwest US Participants Convenience sample (N = 120 of hospitalized persons ≥ 18 years old. Instruments Temperatures (°F measured at oral, skin (simultaneous, immediately followed by rectal sites with four each mercury-glass (BD and Galinstan-glass (Geratherm thermometers; 10 minute dwell times. Results Participants averaged 61.6 years (SD 17.9, 188 pounds (SD 55.3; 61% female; race: 85% White, 8.3% Native Am., 4.2% Hispanic, 1.7 % Asian, 0.8% Black. For both mercury and Galinstan-glass thermometers, within-subject temperature readings were highest rectally; followed by oral, then skin sites. Galinstan assessments demonstrated rectal sites 0.91°F > oral and ≅ 1.3°F > skin sites. Devices strongly correlated between and across sites. Site difference scores between devices showed greatest variability at skin sites; least at rectal site. 95% confidence intervals of difference scores by site (°F: oral (0.142 – 0.265, axilla (0.167 – 0.339, groin (0.037 – 0.321, and rectal (-0.111 – 0.111. Race correlated with age, temperature readings each site and device. Conclusion Temperature readings varied by age, race. Mercury readings correlated with Galinstan thermometer readings at all sites. Site mean differences between devices were considered clinically insignificant. Still considered

The incidence of hypothermia is difficult to evaluate, and the data concerning the morbidity and mortality rates do not seem to fully represent the problem. The aim of the study was to estimate the actual prevalence of accidental hypothermia in Poland, as well as the methods of diagnosis and management procedures used in emergency rooms (ERs). A specially designed questionnaire, consisting of 14 questions, was mailed to all the 223 emergency rooms (ER) in Poland. The questions concerned the incidence, methods of diagnosis and risk factors, as well as the rewarming methods used and available measurement instruments. The analysis involved data from 42 ERs providing emergency healthcare for the population of 5,305,000. The prevalence of accidental hypothermia may have been 5.05 cases per 100.000 residents per year. Among the 268 cases listed 25% were diagnosed with codes T68, T69 or X31, and in 75% hypothermia was neither included nor assigned a code in the final diagnosis. The most frequent cause of hypothermia was exposure to cold air alongside ethanol abuse (68%). Peripheral temperature was measured in 57%, core temperature measurement was taken in 29% of the patients. Peripheral temperature was measured most often at the axilla, while core temperature measurement was predominantly taken rectally. Mild hypothermia was diagnosed in 75.5% of the patients, moderate (32-28°C) in 16.5%, while severe hypothermia (less than 28°C) in 8% of the cases. Cardiopulmonary resuscitation was carried out in 7.5% of the patients. The treatment involved mainly warmed intravenous fluids (83.5%) and active external rewarming measures (70%). In no case was extracorporeal rewarming put to use. The actual incidence of accidental hypothermia in Polish emergency departments may exceed up to four times the official data. Core temperature is taken only in one third of the patients, the treatment of hypothermic patients is rarely conducted in intensive care wards and extracorporeal rewarming

Purpose: The objective of this study was twofold: first, to identify patients with locally advanced breast cancer (LABC) who will achieve a pathological response to a preoperative regimen of concurrent paclitaxel and radiation; and second, to explore associations between molecular markers from the original tumors and pathological response. Methods and Materials: Patients with previously untreated LABC were eligible to receive a regimen of preoperative concurrent paclitaxel, 30 mg/m 2 twice a week for a total of 8 weeks, and radiation delivered Weeks 2-6, 45 Gy at 1.8 Gy per fraction to the breast, ipsilateral axilla, and supraclavicular nodes. At mastectomy, pathologic findings were classified as pathological complete response (pCR) no residual invasive cells in the breast and axillary contents; pathological partial response (pPR) = presence of ≤10 microscopic foci of invasive cells; no pathological response (pNR) = pathological persistence of tumor. For each patient, pretreatment breast cancer biopsies were prospectively analyzed by immunohistochemistry (IHC) for estrogen and progesterone (ER/PR) hormonal receptors, HER2/neu and p53 overexpression. Estrogen receptor (ER), HER2/neu, metablastin, β-tubulin III and IV, microtubule-associated protein-4 (MAP-4), bcl-2, bax, and cyclooxygenase-2 (COX-2) gene expression were measured using real-time quantitative polymerase chain reaction (PCR). Results: A total of 36 patients had pretreatment biopsies and were evaluable for the analysis of the association of molecular markers with pathological response. Pathological response in the mastectomy specimen was achieved in 12 of these 36 patients (33%). Only HER2/neu and ER gene expression were found to be significantly associated with the extent of pathological response to the regimen, i.e., tumors with low HER2/neu gene expression and negative estrogen receptors were more likely to respond to the tested regimen (p=0.009 and p=0.006, respectively). Conversely, p53 protein

In this study, we aimed to compare axillary brachial plexus block using the two-injection and four-injection techniques assisted with ultrasonography (USG) and nerve stimulator in patients operated for carpal tunnel syndrome with articaine. To evaluate which technique is more effective, we compared the onset time, effectiveness, and duration of block procedures, patient satisfaction, adverse effect of the drug, and complication rates of the motor and sensory blocks. Sixty patients were randomly divided into two groups. A mixture of physiologic serum added to articain with NaHCO 3 (30 mL) was injected into the patients' axilla in both the groups. After the blockage of the musculocutaneous nerve in both the groups, the median nerve in the two-injection group and the median nerve, ulnar nerve, and radial nerve in the four-injection group were blocked. In brachial plexus nerves, sensorial blockage was evaluated with pinprick test, and motor block was evaluated by contraction of the muscles innervated by each nerve. The adverse effects and complications, visual analog scale (VAS) values during the operation, and post-operative patient satisfaction were recorded. Sufficient analgesia and anaesthesia were achieved with no need for an additional local anaesthetics in both the groups. Furthermore, additional sedation requirements were found to be similar in both the groups. A faster rate and a more effective complete block were achieved in more patients from the four-injection group. In the two-injection group, the block could not be achieved for N. radialis in one patient. All other nerves were successfully blocked. Whereas the blockage procedure lasted longer in the four-injection group, the VAS values recorded during the blockage procedure were higher in the four-injection group. No statistical difference was found with regard to patient satisfaction, and no adverse effects and complications were observed in any group. Although the multi-injection method takes more time

AIM: To document the varied radiological features before, during, and after treatment of non-Central Nervous System Primitive Neuroectodermal Tumours (PNETs), which are rare tumours of childhood. MATERIALS AND METHODS: Thirty-three children with PNETs have been treated at our institution between 1990 and 1999. Full radiological and clinical follow-up was obtained in 29 (17 females, 12 males). Imaging was retrospectively reviewed, with particular attention to Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). RESULTS: Age range at diagnosis was 0-16 years old (mean 4.4 years). There were five main sites of tumour: head and neck (n = 7), scapula/axilla (n 2), chest (n = 11), abdomen (n = 3), and spinal/paraspinal (n = 6). Overall mortality was 62%. Tumours of the scapula or paraspinal region appear to show better survival than other sites. Of 23 patients who had Tc99m-methylene diphosphonate (MDP) bone scans at diagnosis, four patients showed widespread distant metastases, seven showed focal increased uptake in an adjacent bone only, and 12 had normal examinations. CT was performed in 25 patients and MRI in 20, both at diagnosis and follow-up. Average size of tumours at presentation was 4.5 cm in the paraspinal, head and neck and scapular regions and 7.5 cm in the chest and abdomen. Tumours were typically of soft tissue density on CT with the larger (>5 cm) masses tending to be more heterogeneous in character. The lesions were slightly higher signal than muscle on T1-weighted (T1W) MRI and all masses were heterogeneous on T2W sequences. Calcification was uncommon (n = 6) and generally sparse. Tumours tended to displace adjacent soft tissue structures such as vessels and bronchi rather than invade or encase them. Tumours rarely crossed the midline. Local or bony invasion was seen in 12 patients at diagnosis. Metastases were identified in the lung (n = 5), pleura (n = 2), brain (n = 4), bone (n = 4), lymph nodes (n = 2), liver (n = 2), subcutaneous tissues

2012-01-01

Background: Skin tags (ST) are papillomas commonly found in the neck, axillae of middle-aged and elderly people Aim: Insulin and insulin-like growth factor (IGF-1) levels are affected by hepatitis C virus (HCV) infection and both of them may be implicated in the etiopathogenesis of ST and acanthosis nigricans (AN) through their proliferative and differentiating properties. So, the aim of this work was to evaluate the impact of HCV infection on ST and AN through the estimation of insulin resistance and IGF-1. Materials and Methods: Participants were arranged into four groups: (ST +ve / HCV +ve) 23 subjects, (ST+ / HCV -ve) 19 subjects, (HCV -ve / ST-ve) 20 subjects and (ST-ve /HCV +ve) 22 subjects. Age, ST size, color, number, AN, fasting glucose, fasting insulin, insulin resistance, IGF-1, HCV-antibodies (Ab) were recorded. Results: The mean number of ST in Group 1 was half the number of ST in Group 2 (11.0±9.3 / 22.3±14.0) (P=0.005). The difference in insulin resistance between the same groups was non-significant (13.1±10.6 / 9.0±5.5) (P=0.441) while the difference in IGF-1 was statistically significant (218.6±46.2 /285.4±32.8) (P=0.002). The multivariate logistic regression for the variables revealed that insulin resistance is the only factor affecting the occurrence of ST (OR=1.096, P=0.023). Multivariate regression analysis for the variables showed that HCV was borderline but not a significant factor affecting the number of ST (Beta=-0.409, P=0.053). The number of patients with AN was doubled in Group 2 in comparison to Group 1 but this was non significant 3(13%) / 6(32%) (P=0.2800). Conclusion: HCV is associated with a significant decrease in the ST number and in the serum level of IGF-1 together with an obvious decrease in the occurrence of AN. Our results may point to the entrant effect of insulin resistance and IGF-1 in ST and AN development. The current study suggests the evaluation of IGF-1-lowering agents in the control of ST and AN especially in

Accurate evaluation of axillary lymph node (ALN) involvement is mandatory before treatment of primary breast cancer. The aim of this study is to compare preoperative diagnostic accuracy between positron emission tomography/computed tomography with 18 F-fluorodeoxyglucose ( 18 F-FDG PET/CT) and axillary ultrasonography (AUS) for detecting ALN metastasis in patients having operable breast cancer, and to assess the clinical management of axillary 18 F-FDG PET/CT for therapeutic indication of sentinel node biopsy (SNB) and preoperative systemic chemotherapy (PSC). One hundred eighty-three patients with primary operable breast cancer were recruited. All patients underwent 18 F-FDG PET/CT and AUS followed by SNB and/or ALN dissection (ALND). Using 18 F-FDG PET/CT, we studied both a visual assessment of 18 F-FDG uptake and standardized uptake value (SUV) for axillary staging. In a visual assessment of 18 F-FDG PET/CT, the diagnostic accuracy of ALN metastasis was 83% with 58% in sensitivity and 95% in specificity, and when cut-off point of SUV was set at 1.8, sensitivity, specificity, and accuracy were 36, 100, and 79%, respectively. On the other hand, the diagnostic accuracy of AUS was 85% with 54% in sensitivity and 99% in specificity. By the combination of 18 F-FDG PET/CT and AUS to the axilla, the sensitivity, specificity, and accuracy were 64, 94, and 85%, respectively. If either 18 F-FDG PET uptake or AUS was positive in allixa, the probability of axillary metastasis was high; 50% (6 of 12) in 18 F-FDG PET uptake only, 80% (4 of 5) in AUS positive only, and 100% (28 of 28) in dual positive. By the combination of AUS and 18 F-FDG PET/CT, candidates of SNB were more appropriately selected. The axillary 18 F-FDG uptake was correlated with the maximum size and nuclear grade of metastatic foci (p = 0.006 and p = 0.03). The diagnostic accuracy of 18 F-FDG PET/CT was shown to be nearly equal to ultrasound, and considering their limited sensitivities, the high radiation

Objective: To evaluate and compare spiral CT and positron emission tomography-CT (PET-CT) in characterization of of axillary lymph nodes in breast cancer patients. Methods: Forty patients with pathologically proven breast cancer underwent contrast-enhanced spiral CT of the breast and axilla, 13 of them also underwent PET-CT examination. One hundred and fifty-eight axillary lymph nodes were found in the 40 patients through contrast enhanced spiral CT, while 57 lymph nodes were found in the 13 patients through PET-CT. Three radiologists rated the lymph nodes found in CT images on a five-point scale. If the score was equal to or greater than 3, it was defined as positive (metastatic), otherwise negative. Visual observation and semiquantitative analysis were used to classify lymph nodes in PET-CT images. The results of spiral CT observation and PET-CT observation of lymph nodes were compared with pathological results. The relative value of CT and PET-CT was analyzed. Exact probability statistics were employed. Results: One hundred and fifty eight lymph nodes of 40 patients were detected by spiral CT, 91 of them were diagnosed as positive and 67 as negative Among the lymph nodes found in spiral CT, 99 were positive and 59 were negative pathologicall. A total of 57 lymph nodes were found by PET-CT. Thirty-nine of them were defined as positive and 18 as negative. Among the lymph nodes found in PET-CT, 39 were positive and 18 were negative pathologically. The sensitivity, specificity, accuracy, positive and negative predictive values in CT prediction in axillary lymph nodes metastases were 88.89%, 94.91%, 91.14%, 96.70%, and 83.58%, respectively. The sensitivity, specificity, accuracy, positive and negative predictive values in PET-CT prediction in axillary lymph nodes metastases were 97.44%, 94.44%, 96.49%, 97.44%, and 94.44%, respectively. PET-CT had no significant difference with spiral CT in sensitivity, accuracy, positive and negative predictive values for detection

The present study investigated the clinical application of magnetic resonance (MR)-guided breast interventions, such as manipulator-assisted large core breast biopsy (LCBB) inside a 1.5 T whole-body magnet and MR-guided interstitial laser therapy (ILT). Sixteen patients underwent LCBB and 1 additional patient underwent 4 sessions of ILT of a recurrent undifferentiated lymph node metastasis in the axilla using a Nd-YAG laser (1064 nm). Temperature changes of the tumor tissue during ILT were monitored using phase images of a gradient echo sequence (GRE) (TR/TE/FA = 25/12/30). In 5 patients the biopsy findings were histopathologically confirmed after open surgery. In 3 patients, the biopsy missed one tubular and one ductal carcinoma; one invasive carcinoma was underestimated. Eight patients with benign findings are still in the follow-up period. The heating zone during ILT was well delineated on subtracted phase images. No severe adverse events were observed with LCBB or ILT. MR-guided breast biopsies are feasible with the manipulator system inside a whole-body 1.5 Tesla MR scanner. GRE information is suitable for therapy monitoring during ILT within the tumor. Further studies are necessary to evaluate the accuracy of the manipulator system and the efficacy of ILT in the treatment of breast lesions. (orig.)

Purpose: We have retrospectively reviewed our institution's experience treating a predominantly mammographically detected population of ductal carcinoma in situ (DCIS) patients with conservative surgery and radiation therapy (CSRT) to determine outcome and prognostic factors for local recurrence. Methods and Materials: Between January 1, 1982 and December 31, 1988, 52 consecutive cases of DCIS of the breast were treated with CSRT at William Beaumont Hospital. Forty-six (88%) were mammographically detected nonpalpable lesions. All patients underwent at least an excisional biopsy and 28 (54%) were reexcised. The axilla was surgically staged in 41 (79%) and all were N0. The entire breast was irradiated to 45-50 Gy over 5-6 weeks. The tumor bed was boosted in 49 (94%) so that the minimum dose was 60 Gy. The three patients not boosted received a minimum dose of 50 Gy to the entire breast. Pathologic materials were reviewed by one of the authors. Results: The predominant DCIS pattern was comedo in 40%, cribriform in 28%, solid in 17%, and micropapillary in 15%. The predominant nuclear grade was Grade I in 51%, Grade II in 49%, and Grade III in 0%. The median follow-up is 68 months. There have been three recurrences in the treated breast at a median time to failure of 30 months. The 5- and 8-year actuarial local recurrence rate is 6%. One patient recurred with invasive ductal cancer at 28 months, and the other two recurrences were DCIS at 30 and 50 months. All three patients were treated with salvage mastectomy. The patient who recurred locally with an invasive cancer developed metastasis and died at 64 months. The 5- and 8-year actuarial cause-specific survival rates are 100% and 97%, respectively. The following pathologic factors were analyzed for an association with local recurrence: predominant DCIS histology, predominant nuclear grade, and highest nuclear grade. Of these, the predominant nuclear grade was the best predictor of local recurrence (p = 0.070). No

Full text: Thanks to the International Atomic Energy Agency and co-operation of the Nuclear Regulatory Authority of the Slovak Republic - International and Public Relations Division, sentinel lymph node detection has been introduced in one of the regional hospitals in Slovakia. Surgical Gamma Probe, the equipment needed for this has been made available. IAEA first of all helped in organizing a workshop on Scintimammography, Sentinel Lymph Node Detection and Intra-Operative Surgical Probe in Breast Cancer, in April 2002. Education of specialists - surgeons, oncologists, and pathologists and of course radiologists helped them to better understand the subject visa-vis nuclear medicine techniques. We also started the sentinel node detection following the two-days protocol. A 57 years old female with newly detected breast carcinoma in right breast, with positive mammography was investigated. Axillary lymph nodes were not palpable. Tc-99m Nanocoll, with particles size ranging 4-100 nm, was administered, 75 MBq peritumorally + 75 MBq subdermally and a dynamic lymphoscintigraphy was acquired which showed migration of the radiotracer. Static views (after 120 min.) demonstrated 4 sentinel lymph nodes in the right axilla. No lymph node was seen in the internal mammary or left axillary region. Next day before operation about 2 ml of patten blue dye was injected around the tumor and breast was compressed for about 10 min. Identification of sentinel lymph node was done with the help of surgical gamma probe and blue tinting. We found 6 nodes, first two were not really sentinel, but they were blue. A breast conservation surgery with standard axillary lymphadenectomy was performed. Pathology revealed invasive ductal carcinoma. We understand the need to establish an algorithm of examination and treatment of patients with newly diagnosed breast carcinoma. This technology requires teamwork of surgeon, nuclear medicine physician and pathologist. Regarding radiation exposure which every

To determine the utility of {sup 18}F-FDG (FDG) PET/CT performed in an early and delayed phase during neoadjuvant chemotherapy in the prediction of lymph node histopathological response in patients with locally advanced breast cancer. FDG PET/CT studies performed in 76 patients (mean age 53 years) at baseline (PET-1), after the second course of chemotherapy (PET-2) and after the last course of chemotherapy (PET-3) were prospectively analysed. Inclusion criteria were lymph node involvement detected by PET/CT and non-sentinel node biopsy before or after the baseline PET/CT scan. Following the recommendations of the 12th International Breast Conference (St. Gallen), the patients were divided into five subgroups in relation to biological prognostic factors by immunohistochemistry. For diagnosis visual and semiquantitative analyses was performed. Absence of detectable lymph node uptake on the PET-2 or PET-3 scan with respect to the PET-1 scan was considered metabolic complete response (mCR). Lymph nodes were histopathologically classified according the lymph node regression grade and in response groups as pathological complete response (pCR) or not pCR (type A/D or B/C of the Smith grading system, respectively). ROC analysis was performed to determine a cut-off value of Δ% SUV1-2 and SUV1-3 for prediction of nodal status after chemotherapy. An association between mCR and pCR was found (Cohen's kappa analysis), and associations between phenotypes and metabolic behaviour and the final histopathological status were also found. Lymph node pCR was seen in 34 patients. The sensitivity, specificity, and positive and negative predictive values of PET-2 and PET-3 in establishing the final status of the axilla after chemotherapy were 52 %, 45 %, 50 % and 47 %, and 33 %, 84 %, 67 % and 56 %, respectively. No significant relationship was observed between mCR on PET-2 and PET-3 and pCR (p = 0.31 and 0.99, respectively). Lymph node metabolism on PET-1 was not able to predict

Full Text Available Abstract Background Suction drains are routinely used after modified radical mastectomy and are an important factor contributing to increased hospital stay as the patients are often discharged only after their removal. Amongst various factors that influence the amount of postoperative drainage, the negative suction pressure applied to the drain has been reported to be of great significance. While a high negative suction pressure is expected to drain the collection and reduce the dead space promptly, it may also prevent the leaking lymphatics from closing and lead to increased drainage from the wound. Against this background a prospective randomized clinical study was conducted to compare the amount and duration of drainage between a half negative suction and full vacuum suction drainage in patients following modified radical mastectomy. The associated postoperative morbidity was also compared between the two groups. Methods 85 FNAC (fine needle aspiration cytology proven cases of locally advanced breast cancer were randomized. (Using randomly ordered sealed envelops, which were opened immediately before the closure of the wound in to 50 patients with full vacuum suction (pressure = 700 g/m2 and 35 cases in to half vacuum suction drainage (pressure = 350 g/m2 groups. The two groups were comparable in respect of age, weight, and technique of operation and extent of axillary dissection. Surgery was performed by the same surgical team comprising of five surgeons (two senior and three resident surgeons using a standardized technique with electrocautery. External compression dressing was provided over the axilla for first 48 hrs and following that patients were encouraged to do active and passive shoulder exercises. The outcomes measured were postoperative morbidity and the length of hospital stay. Statistical methods used: Descriptive studies were performed with SPSS version 10 and group characteristics were compared using student t-test. Results

We describe and name a new species of poison-dart frog from the Amazonian slopes of the Andes in Manu Province, Madre de Dios Department, Peru; specifically within the Amarakaeri Communal Reserve and the buffer zone of Manu National Park. Ameerega shihuemoy sp. nov. is supported by a unique combination of characters: black dorsum with cream to light orange dorsolateral lines, blue belly reticulated with black, and the lack of axillary, thigh and calf flash marks. Within Ameerega, it shares the general appearance of A. altamazonica, A. boliviana, A. hahneli, A. ignipedis, A. petersi, A. picta, A. pongoensis, A. pulchripecta, A. simulans, A. smaragdina, and A. yungicola; each possessing a granular black to brown dorsum, a light labial bar, a conspicuous dorsolateral line running from the snout to the groin, and a metallic blue belly and underside of arms and hind limbs. From most of these species it can be distinguished by lacking flash marks on the axillae, thighs, and calves (absent in only A. boliviana and A. smaragdina, most A. petersi, and some A. pongoensis), by having bright cream to orange dorsolateral stripes (white, intense yellow, or green in all other species, with the exception of A. picta), and by its blue belly reticulated with black (bluish white and black in A. boliviana, green and blue with black marbling in A. petersi, and green and blue lacking black marbling in A. smaragdina). Its mating call also shows clear differences to morphologically similar species, with a lower note repetition rate, longer space between calls, and higher fundamental and dominant frequencies. Phylogenetic analyses based on the 16S mitochondrial rRNA fragment also support the distinctiveness of the new species and suggest that A. shihuemoy is most closely related to Ameerega macero, A. altamazonica, A. rubriventris, and two undescribed species (Ameerega sp. from Porto Walter, Acre, Brazil, and Ameerega sp. from Ivochote, Cusco, Peru). Genetically, the new species is most

We report on a young man who presented at our emergency unit with pain and swelling of his left hand, after he had been bitten into his left middle finger by a sidewinder rattlesnake one hour ago. Local findings were a swollen left middle finger, a red-livid discoloration along his nail rim with paleness of the surrounding skin. Vital signs were stable, ECG showed sinus rhythm, laboratory parameters were normal, without signs of liver or kidney damage and without coagulopathy. Diagnosis was local tissue reaction due to a snake bite of a sidewinder rattlesnake without evidence of systemic toxic effect. Due to the absence of systemic toxic effects the patient received monitoring of his vital signs and we controlled local tissue reaction constantly and laboratory parameters every 6 hours, as recommended by the "Giftnotrufzentrale" (poison emergency advisory service). The patient left hospital on his own will against medical advice in the night after first laboratory control, which showed no signs of organ damage and we recommended reasessment the following morning. At that time the swelling had extended to the whole arm, furthermore large hematoma reaching up to the axilla had developed over night. Again we contacted the "Giftnotrufzentrale" and decided to begin the administration of an antivenom, after allergic testing. The administration was without complications, the swelling decreased constantly and since laboratory controll still showed no signs of systemic toxin effect, we could discharge the patient on day 3. Follow-up visit 6 months later showed complete and natural healing. Snake bites are altogether rare among our patients, nevertheless since possible toxin effects and its dynamics are unpredictable and can vary highly, they demand monitoring at close intervals of vitals signs, local swelling and laboratory parameters. As early as possible an advisory service, such as "Giftnotrufzentrale" should be contacted to acquire information on possible toxin effects

Purpose: This study retrospectively assesses the patterns of failure in conservatively treated early stage breast cancer patients by correlating various clinical, pathologic, and treatment-related factors with local, axillary, and distant relapse. Methods and Materials: Between 1973 and 1990, 796 patients (817 breasts) received breast conservation surgery followed by radiotherapy. Local recurrences were counted as events even if they occurred simultaneously or after the appearance of axillary or distant metastases. Results: The 10-year actuarial relative disease-free survival (DFS) rate for T1N0, T2N0, and T1-2N1 was 82%, 71%, and 54%, respectively. Stage N0 patients had a significant DFS advantage over N1 patients (p = 0.02). The 15-year actuarial local recurrence-free rate for T1 and T2 tumors was 82% and 87%, respectively (p = nonsignificant). Univariate analysis identified three significant risk factors for local relapse: (a) 48 breasts with tumors showing an extensive intraductal component had a crude local recurrence rate of 23% compared to 8% for 769 breasts without intraductal component (p 0.0016); (b) the actuarial 10-year local recurrence-free rate for patients under age 40 years was 64% compared to 88% for patients over 40 years (p < 0.0001); (c) the 10-year actuarial local recurrence-free rate for 416 postmenopausal women without adjuvant tamoxifen was 83% compared to 97% for 107 postmenopausal women with tamoxifen (p = 0.0479). Salvage therapy for operable local recurrent patients resulted in a 8-year actuarial DFS rate of 47%, significantly lower than that obtained with primary treatment. The incidence of axillary relapse as the first sign of recurrence was 2%, and could be correlated with the lack of axillary dissection (p < 0.0000005) and primary tumor size (p = 0.03). Radiotherapy to the axilla did not influence axillary relapse. Actuarial 5-year DFS rate after treatment of isolated axillary recurrence was 27%. Axillary failure was a marker for

Full Text Available We present a 55-year-old male patient - a smoker, admitted to a Medical Institute of MVR (Ministry of the interior, Sofia, Bulgaria, on occasion of pain and swellings, located in the area of both axillae, accompanied by purulent discharge, with bloody admixtures. Bilateral localised cystic rose above the skin surface, hyperpigmented nodules interconnected with multiple fistulas, was observed within the dermatological examination, resulting in a limitation of the possibility of movement of the hands in all directions. A subjective complaint of pain was obtained on palpation. Solid bilateral axillar cicatrices - formation was also established, which additional impeded the movements of the upper limbs. The disease was generalised affecting additional inguinal, femoral and perineal areas, while at this stage the patient refused categorically eventual photo documentation of them. The diagnosis of acne inversa was made based on the available clinical and para-clinical data, as dual antibiotic therapy with Clindamycin 300 mg, two times per day was initiated for two months, in combination with rifampicin 300 mg, two times per day also for two months. This led to a significant improvement in the clinic symptoms and the patient was hospitalised for radical surgery. A surgical management of the clinical findings was planned by an interdisciplinary team including surgeons and dermatologists. The procedure was performed under general anaesthesia. After a thorough cleaning of the operative field, a radical excision of the lesion in the left axillary and para axillar region was performed, comprising the skin and subcutaneous tissue forward the fascia pectoralis. Tissue was dissected in depth in the form of number 4, thereby creating the conditions for adaptation of the initially encountered communicating with each other skin defects. Two tubular drains were placed, followed by gradual suturing of skin and subcutaneous tissue with final applying of a sterile

Pituitary stalk interruption syndrome is a rare congenital abnormality of the pituitary that is responsible for anterior pituitary deficiency. It is characterized by a classic triad of interrupted pituitary stalk, absent or ectopic posterior pituitary, and anterior pituitary hypoplasia or aplasia. Clinical presentation varies according to age. In adults it presents as short stature and anterior pituitary deficiency. Without early diagnosis and treatment, mortality and morbidity in these patients is high. Early diagnosis and treatment of this rare disease can prevent permanent short statue of the patient. We report the first case of pituitary stalk interruption syndrome from Pakistan. A 17-year-old Pakistani young man presented with short stature and underdeveloped secondary sexual characters. His siblings and parents were healthy, with normal height. An examination showed his blood pressure was 90/60 mmHg, and his height, weight, and body mass index were 142 cm, 34.5 kg, and 17.10 kg/m2, respectively. He had no hair growth on his face, axilla, or pubis. His testes were between 1 and 2 mL in size, with a 4 cm-at-stretch micropenis. His lab investigations showed that his thyroid stimulating hormone (TSH) was 8.58 uIU/mL (0.4 to 4.2), his free thyroid hormone level FT4 was 0.46 ng/dL (0.89 to 1.76), his prolactin was 21.1 ng/mL (3.0 to 14.7), and his baseline cortisol was 0.30 ug/dL (4.3 to 22.4). His cortisol level after 60 minutes of cosyntropin injection was 3.5 ug/dL (4.3 to 22.4), his insulin like growth factor IGF-1 was 31.56 ng/mL (247.3 to 481.7), his testosterone level was under 2.5 ng/dL (2 to 800), his follicle stimulating hormone FSH was 0.41 uIU/mL (0.0 to 10.0), and his leutinizing hormone LH was under 0.1 uIU/mL (1.2 to 7.8). His bone age was 10 years according to the Greulich and Pyle method, as shown by X-rays. The results from his pituitary magnetic resonance imaging scan were consistent with pituitary stalk interruption syndrome. We describe a young

Sulfur Mustard ((SM; 2, 2 -dichlorethyl sulfide)) is a potent chemical warfare agent that was widely used during First World War and Iran -Iraq conflict. Over 100,000 Iranians were injured by sulfur mustard. This vesicant agent has a lot of acute and chronic destructive influences on the skin, eye and respiratory system. SM via the alkylation of DNA and several cellular proteins (structural, cytoplasmic and enzymes) and cell nuclei; produce several toxic, mutagenic and carcinogenic effects on epidermis, dermis, dermal appendix and hypodermics. In acute phases flexural locations and thin epidermal area such as groin, scrotum, and axilla and eyelids showed the most severe complication. According to scientific studies on chemical victims depression of cell-mediated immunity and also lower percentage of NK cell has been observed in SM exposure furthermore cytokines and other growth factors produced and secreted during epidermal and dermal regeneration of healing skin blisters. In reference to the last study about long term effect of SM the cutaneous signs and disorders could be categorized into 3 different groups. Conclusion Human data on the carcinogenicity of SM are from (a) battlefield exposures, (b) accidents, and (c) workers in chemical factories. Both British and American studies and other researchers have investigated the increased incidences of leukemia, pulmonary and skin carcinoma arising from World War I battlefield exposure. Clinical documentation in our cases shows notable and common signs, symptoms and data such as 1- Middle ages 2- Location of CTCL (folds and exposed areas) 3- The similarity between CTCL and SM scar (pigmentory and vascular changes) 4- Chronic dermatitis especially xerosis and eczema with itching before the beginning of CTCL. All of this study and data leads us to the conclusion that SM can possibly cause CTCL in indirect and direct way. CTCL can be caused indirectly due to prolonged period of chronic dermatitis (xerosis, eczema

Full Text Available Los neurinomas del plexo braquial son tumores infrecuentes que pueden confundirse con otras lesiones de índole tumoral. Se presenta el caso de una mujer de 40 años, tratada previamente de un adenocarcinoma de mama derecha en el pasado, que en el estudio de extensión realizado 5 años después se detectó una lesión localizada en el plexo braquial derecho. La paciente se encontraba asintomática. El diagnóstico radiológico de presunción fue metástasis de adenocarcinoma mamario. Se realizó un abordaje axilar derecho descubriendo una lesión bien delimitada en el plexo braquial. Con ayuda de la monitorización neurofisiológica intraoperatoria, se observó que la lesión dependía de la rama cubital y se pudo realizar una resección completa preservando la función de dicho nervio. El estudio anatomopatológico confirmó que se trataba de un neurinoma, descartando así la existencia de metástasis. La evolución postoperatoria fue satisfactoria. Seis años después de la intervención no existe recidiva tumoral. En nuestro conocimiento este es el primer caso publicado en la literatura de un neurinoma del plexo braquial dependiente de la rama cubital. La monitorización neurofisiológica intraoperatoria resulta fundamental para abordar este tipo de lesiones con baja morbilidad.Schwa nomas originating from the brachial plexus, although rare, may be mistaken for another type of tumour. A 40 year-old woman, who had been treated years earlier for a breast adenocarcinoma, showed in the 5-year follow-up magnetic resonance examination a localized lesion in the right brachial plexus. The presumptive radiological diagnosis was a metastasis from the primary adenocarcinoma. Following surgical access via the right axilla, a well-circumscribed mass in the brachial plexus was detected. Under intraoperative electrophysiological guidance, the lesion was observed to depend on the ulnar nerve and its complete resection was possible without compromising nerve

Car safety seat misuse did not improve following implementation of a comprehensive nursing education and training program. CSS misuse in our study population was frequent and may increase injury risk in the event of a motor vehicle crash. Future work is needed to develop novel approaches and identify appropriate settings to reduce newborn CSS misuse.

broad ligament and the ventral rectal serosa, and the 'prolapsed' tissue was found to be expanded vaginal wall. The bitch was euthanased and necropsied, Histological examination confirmed lymphangiosarcomatous invasion of the submucosal and muscular layers of the retroperitoneal, traumatised, prolapsed part of the vagina, the urethra and the ventral rectal wall. The broad ligament was diffusely invaded with tumour which had proliferated into the caudal abdominal space, and 3 small intra-trabecular foci of tumour were found in the right popliteal lymph node near the hilus. Mitotic figures were generally scarce. There was mild subcutaneous oedema of the ventral trunk extending from the axillae to the inner proximal thighs, which had not been evident clinically, and the lymph nodes (peripheral more so than internal microscopically showed marked trabecular and perivascular fibrosis especially in hilar regions. Other congenital defects were hepatic capsular and central venous fibrosis with lymphatic duplication and dilatation in all areas of connective tissue, ventrally-incongruous half-circular tracheal rings, and multifocal renal dysplasia affecting the right kidney. There was locally-extensive subacute pyelonephritis of the left kidney.

Full text: It is already known that breast cancer is the most common malignancy in women. Physical breast examination and mammography are currently the most recognized screening tools for detection of breast cancer. However, breast mammography has some limitations, especially in women with dense breast or in patients who have had surgery, radiotherapy or chemotherapy. The aim of this study was to investigate the role of Tc-99m Sestamibi scintimammography in the diagnosis of breast cancer. Forty-two women (median age= 46 years, range 21-78 years) were investigated. All had a thorough clinical examination, ultrasonography, mammography, determination of the level of tumor markers - CA15.3 and CEA, fine needle aspiration cytology (FNA) and scintimammography before surgery. The final diagnosis was determined by histopathological examination. For scintimammography, a dose of 740 MBq of Tc-99m sestamibi was injected into a foot vein followed by 10ml saline flush. Imaging was performed 10 minutes later in prone position; lateral views of the breasts and axilla were taken (10 minutes per view, matrix size 128x128, high resolution collimator). Anterior views of the breast and axillary areas were also acquired with patients in supine position. Delayed scintigraphy in prone position (lateral view) was done 60 minutes after injection. Focal accumulation of sestamibi in tumor on early and delayed scintigraphy was considered positive. The results of scintimammography were compared with histopathology. The histopathological results revealed malignancy in 33 (78.6%) and benign tumors in 9 (21.4%) cases. Scintimammography showed true positive findings in 31 (73.8%) patients having breast cancer. It was false negative in 2 cases (1 of invasive ductal carcinoma and 1 of invasive lobular carcinoma). All 5 cases with nonpalpable invasive ductal carcinoma and two cases with ductal carcinoma in-situ were positive on scintimammography. True negative findings with no focally increased

Verneuil's disease, or hidradenitis suppurativa, is a chronic suppurative disease with a tendency to sinus formation, fibrosis, and sclerosis. It is a disease of the apocrine sweat glands and may arise from each of the localizations where apocrine glands are prominent: axilla, nipples, umbilicus, perineum, groin, and buttocks. Extensive hidradenitis suppurativa of the perineal/perianal and the gluteal regions constitute a serious social problem. In this study, we present our experience with stage III extensive hidradenitis suppurativa cases, including our treatment methods and patient outcomes. A retrospective review of the medical records from January 1990 to July 2003 of 15 patients was performed. Fifteen patients underwent treatment for extensive hidradenitis suppurativa in the gluteal, perineal/perianal, and inguinal areas with total surgical excision. All patients were men (100%) and their mean age was 42.5 (range, 23-66) years. The patients underwent a total number of 21 operations. In 11 patients wounds were left open for secondary healing, and the mean time for complete wound healing in this group was 12.2 (range, 9.5-22) weeks. Two patients underwent primary wound closure by the application of rotation flaps, and their complete healing times were observed to be approximately 2 weeks. Delayed skin grafting was used for the remaining two patients in whom the wounds had been left open after the initial operation. In this group, complete wound healing took a total of 8 weeks. Only one diverting colostomy was needed in a patient in the delayed skin-grafting group. Squamous cell carcinoma was diagnosed in the specimens of one patient treated with total excision followed by the application of a rotation flap. This patient had had complaints of gluteal discharge for approximately 30 years. The cancer recurred after 6 months in the perianal region and immediate abdominoperineal resection was performed. He died during the second postoperative month due to systemic

, skin, subcutaneous cellular tissue and peritoneum. Continuity with the round ligament and the urachus allows dissemination through those structures. Such facts justify the difficulty faced while establishing vertical or horizontal growth of Melanomas, as well as using Breslow measurements in that area. In addition to that, the lymphatic drainage, as a function of the classical definition of the Sappey Line, can be directed towards the axillary or inguinal areas, thus making it essential to carry out lymphoscintillography and lymphatic mapping. Conclusion: Umbilical melanoma is a rare occurrence. Due to its embryological and anatomical peculiarities, its clinical histopathological evaluation entails difficulties and demands knowledge of local lymphatic drainage aspects in order to determine its pattern of dissemination. Lymphoscintillography and lymphatic mapping are imposed with sentinel lymph node research as exclusive means for identifying the routes of lymphatic drainage. In this case, we were able to define the drainage for the left axilla and to recover the corresponding lymph nodes, so that histopathological and immunohistochemical exams could be carried out.

Advances in suction-assisted lipectomy (SAL) include improved instrumentation, better understanding of fluid dynamics, and an improved concept of appropriate indications. The tumescent technique uses subcutaneous injection of isotonic fluid containing vasoconstrictive and analgesic agents and is proved to be safe, with low morbidity and mortality rates. Laser-assisted liposuction (LAL) using local infiltration of an anesthetic and no general anesthesia or sedation has been developed, with claims of fat destruction and skin tightening. This study aimed to review 1,000 consecutive cases of LAL and SAL performed with the patient under local anesthesia and to determine whether this represents a safe technique with few complications. During a period of 22 months, 581 consecutive patients (486 females and 95 males) underwent 1,000 LAL/SAL operations, 545 of whom had multiple procedures performed. None of the patients had a body mass index (BMI) higher than 30 kg/m2. The patients ranged in age from 18 to 62 years. The fat aspirate ranged from 50 to 1,400 ml. Patients were given an oral sedative, an antibiotic, and an analgesic. Ringer's lactate solution containing lidocaine and epinephrine was injected into the subcutaneous space. The 1,064-nm and/or 1,320-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser was used for laser lipolysis followed by SAL using standard and/or power-assisted liposuction (PAL) cannulas. The treated areas included the neck, triceps, male breast, midback, flanks, axilla, abdomen, mons pubis, thighs, presacrum, and knees. No patient was administered intravenous sedation or general anesthesia. The average number of areas treated was 1.8, and no major complications or mortalities were observed. There were three burns, two infections, one hematoma, and one seroma. A total of 73 secondary procedures were performed (7.3%). No tertiary procedures were required. For appropriately selected patients, comparable results can be obtained with an excellent

side of the scrotum', 'front side of the scrotum', and 'around anus', but not all pair differences were significant. The rank order was similar for 'orgasm intensity', but less similar and with fewer significant pair differences for 'orgasm effort'. Overall discrimination of other body parts that help orgasm when touched/stimulated was also highly significant (P = 0.001) and included (in order of degree) scrotum, ear, skin between scrotum and anus, neck, breast/nipples, buttocks, anus (exterior skin), anus (inside with penetration), wrist, and axilla, but many pair differences were not significant. In the reliability study, which was limited to the 45 function items with sufficient variability and sample size, the re-test reliability values (Pearson r) were distributed as follows: seven were >or=0.80, 16 >or=0.70, 15 >or=0.60, four >or=0.50, two >or=0.40, and one >or=0.30. The SAGASF-M discriminates reasonably well between various genital and nongenital areas in terms of erotic sensitivity, when administered to genitally unoperated men varying widely in age and socio-economic level.

korrelierten die Befunde mit den histopathologischen Ergebnissen. Ergebnisse: Die Lymphszintigraphie konnte unter Verwendung von statischen Einzelaufnahmen 1-2 h p.i. nur bei 62 von 110 so untersuchten Patientinnen einen SLN nachweisen entsprechend einer Sensitivitaet von 56%. Mittels Lymphsequenzszintigraphie lag die Sensitivitaet dagegen bei 86% (19 von 22 Pat.). Die praeoperative Gammasondenmessung detektierte mindestens einen SLN bei Patientinnen mit klinisch unauffaelliger Axilla in 96% (113 von 118 Pat.), intraoperativ fand sich bei 2 weiteren Patientinnen des SLN und die Sensitivitaet lag bei 97% (115 von 118 Pat.). Nur bei 3 Patientinnen mit klinisch unauffaelligen axillaeren Lymphknoten konnte mit der Sondentechnik kein SLN detektiert werden. Die histologische Aufarbeitung ergab bei 2 Patientinnen sogenannte skip lesions, d.h. Lymphknotenmetastasen bei tumorfreiem SLN, mit entsprechend alasch negativem Lymphknotenstaging durch die SLN-Biopsie. Schlussfolgerung: Mit der Lymphsequenzszintigraphie und der praeoperativen Gammasondenmessung lassen sich bei Mammakarzinompatientinnen der Lymphabstrom aus der Brust und SLN zuverlaessig darstellen. Die Nuklearmedizin kann somit die fuer die SLN-Biopsie erforderliche Methodik routinemaessig zur Verfuegung stellen. (orig.)

Extensive Peculiar Cutaneous Form of Neurofibromatosis Type I as a New Mutation - a Case Report

Full Text Available Neurofibromatosis-1 (NF1 is one of the most common hereditary multisystemic disorders. The disease manifests a variety of characteristic features that include: hyperpigmentary abnormalities of the skin (café-au-lait macules, freckles in the axillae, and iris Lisch nodules and growth of benign peripheral nerve sheath tumors (neurofibromas in the skin. Associated extracutaneous clinical features include: skeletal abnormalities, neurological, cardiovascular, endocrine and other malformations. NF1 is caused by mutation in the neurofibromatosis-1 gene, which codes for the protein neurofibromin. The inheritance of NF1 follows an autosomal dominant trait, although about 50% of patients present with new („de novo“ mutations, and represent the first member of their family. No difference in the severity of the disease can be found in patients with familial mutations versus those with new mutations. We present a 78-year-old female patient with an extreme cutaneous form of neurofibromatosis who reported no affected family member. Apart from skin problems, she had no major health issues in childhood and adolescence, but in recent decades she had frequent headaches, occasional abdominal pain, and vision and hearing impairment. About 10 to 14 days before admission, she developed a severe cough, shortness of breath, and chest and abdominal pain. On examination, the patient of short stature (hight: 152 cm, weight: 49 kg presented with thousands of soft nodules dispersed over the whole body, except on extensor sides of thighs and lower legs; the nodules varied in color from skin-colored, livid erythematous, to brown-grey; the nodules on the abdomen were moist, partly bleeding from the base, and accompanied by an unpleasant odor. Her feet were also densely covered by dark purple lumps, with dystrophic changes of the toe nails that were thickened, frayed, and yellowish. The skeletal abnormalities included: short stature, severe osteoporosis and osteosclerosis
