    During routine dissection of an approximately 50-year-old male cadaver for the undergraduate medical students at Melaka Manipal Medical College, Manipal University, Manipal, we came across a variation in branching pattern of right axillary artery. The second part of axillary artery gave rise to a common trunk which divided into the subscapular and lateral thoracic arteries. The third part of right axillary artery gave rise to anterior and posterior circumflex humeral arteries. Variations in t...

    Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, and thoracotomy causing significant morbidity and mortality rates. Endovascular techniques may offer an alternative to these surgically demanding procedures. We present a patient with a traumatic dissection of the axillary artery following anterior shoulder dislocation who was successfully managed with an endovascular stent. PMID:18411587

    Full Text Available Axillary artery and its branches are prone to have variations in their course. Knowledge about such variations are important for Radiologists in imaging techniques, Surgeons,Orthopedicians and Anesthetists in performing surgeries in the axilla and giving regional nerve blocks in the axilla.During dissection of a cadaver in the department of Anatomy, PSG IMS &R, Coimbatore, We observed a variation in the third part of right Axillary artery. From the common trunk, Subscapular artery, Anterior and Posterior circumflex humeral arteries and Profunda brachii artery arose. Third part of Axillary artery continued down as brachial artery. We are highlighting the variation in this study.

    Full Text Available Abstract The arterial cannulation site for optimal tissue perfusion and cerebral protection during cardiopulmonary bypass (CPB for surgical treatment of acute type A aortic dissection remains controversial. Right axillary artery cannulation confers significant advantages, because it provides antegrade arterial perfusion during cardiopulmonary bypass, and allows continuous antegrade cerebral perfusion during hypothermic circulatory arrest, thereby minimizing global cerebral ischemia. However, right axillary artery cannulation has been associated with serious complications, including problems with systemic perfusion during cardiopulmonary bypass, problems with postoperative patency of the artery due to stenosis, thrombosis or dissection, and brachial plexus injury. We herein present the case of a 36-year-old Caucasian man with known Marfan syndrome and acute type A aortic dissection, who had direct right axillary artery cannulation for surgery of the ascending aorta. Postoperatively, the patient developed an axillary perigraft seroma. As this complication has, not, to our knowledge, been reported before in cardiothoracic surgery, we describe this unusual complication and discuss conservative and surgical treatment options.

    The need to bypass to the brachial artery is rare. Over a five-year period, 16 patients had suffered iatrogenic post-catheterization injuries of the upper extremity. We have performed 16 bypasses, in 16 patients, mean age was 65 years (range 47-75), to the brachial artery originating from an artery proximal to the shoulder joint. In all cases, the axillary artery was the donor artery. All bypasses were created by using the cephalic vein with the in situ technique and distal anastomoses were made to a distance-free section of brachial artery. No operative mortality, neurological complications or major upper-extremity amputation was associated with the procedure. Life-long-conduit analysis showed 75% patency in the five-year period. After iatrogenic post-catheterization trauma of arterial system of upper extremity, bypasses from axillary to brachial artery with the cephalic vein with the in situ technique is a safe operation with satisfactory long-term patency.

  7. Axillary artery aneurysm in tuberous sclerosis: cross-sectional imaging findings

    International Nuclear Information System (INIS)

    A 10-month-old boy with a known diagnosis of tuberous sclerosis presented with axillary and brachial masses. Cross-sectional imaging with computed tomography, magnetic resonance, and ultrasound demonstrated unsuspected aneurysms of the axillary and brachial arteries. The results of these studies significantly changed the preoperative planning for this patient, who was scheduled for a biopsy of a presumed soft-tissue tumor. To our knowledge, this is the first description of the cross-sectional imaging findings in the extremity peripheral vascular manifestation of tuberous sclerosis; it has only been previously described on angiography in one case. The rare association of peripheral arterial aneurysms with tuberous sclerosis is important to recognize not only for clinical diagnosis but also for appropriate surgical treatment and genetic counseling.

    Full Text Available Abstract Aim Brief case report of the treatment of a large axillary artery pseudoaneurysm after a pacemaker using a left brachial cutdown and a retrograde delivery of a covered stent using ultrasound and fluoroscopic guidance. The patient's renal function precluded the use of contrast materials. Case Report A 77 years old man presenting with acute renal failure and haemoglobin decrease arrived with an expanding pseudoaneurysm of the left axillary artery from a pacemaker placement. Considering the site of the lesion and patient's comorbidities, under echographic control, a Hemobahn® stent-graft was placed; fluoroscopy assisted manipulation of guidewires and sheaths into the aortic arch. The procedure was successfully ended without any complications. At 8 months the stent graft was still patent. Conclusion Ultrasound guidance may represent an alternative for pseudo-aneurysm exclusion without any use of contrast medium, especially in those patient where lesions are easily detectable using ultrasonography and when comorbidities contraindicate aggressive surgical or angiographic approach.

    Anesthetic management of patients with coagulation disorders presents safety and technical challenges. This case describes a 58-year-old woman with factor V Leiden mutation who required distal saphenous vein harvest and axillo-brachial bypass to treat axillary artery occlusion. The patient underwent surgery with satisfactory anesthesia using infraclavicular brachial plexus block, thoracic paravertebral block, and unilateral subarachnoid block. These three regional anesthetic interventions were performed in lieu of general anesthesia to minimize risks of thrombotic events, pain, and to decrease recovery time. Despite higher failure rates of regional anesthesia, longer time required for procedures, and added discomforts during surgery, the benefits may outweigh risks for selected high-risk patients, including those with factor V Leiden mutations.

    The catheter-based Impella 5.0 left ventricular assist device (LVAD) is a powerful and less invasive alternative for patients in cardiogenic shock. The use of this device as a primary mechanical circulatory support strategy in INTERMACS II patients should be evaluated. From April 2014 to August 2014, eight Impella 5.0 devices were implanted in seven patients via the axillary artery access (six right and two left). We analyzed the outcome of the four patients in whom the Impella 5.0 device was implanted for the purpose of primary stabilization of cardiogenic shock (INTERMACS II). The remaining three patients had a contraindication for a permanent LVAD and received the device for prolonged weaning from extracorporeal life support (ECLS) system. The implantation of the Impella 5.0 was technically successful in all patients and resulted in the stabilization of the clinical situation. All four patients could be bridged to a long-term device (n = 3) or to cardiac recovery (n = 1). In one patient, 2 days of ECLS support was necessary because of pump thrombosis after 31 days of Impella 5.0 support. One patient with bronchopneumonia had the Impella 5.0 exchanged from the right to the left axillary artery after 22 days of support because of the progressive loss of purge flow and the need for longer bridging to a permanent LVAD. The last patient was supported for giant-cell myocarditis for 22 days and bridged to cardiac recovery. All patients were transferred to the intensive care unit with the Impella device in place. In INTERMACS II situations, the implantation of the Impella 5.0 via the right or left axillary access allowed additional time for decision making. Early patient mobilization, including walking with the Impella device in place, optimized the conditions for either weaning or the implantation of a permanent LVAD. This novel technique of left axillary approach leads to more flexibility in the case of anatomical- or device-related contraindications to right

    We discuss the case of an independent 80-year-old Caucasian woman, being treated with new oral anticoagulants for a previous deep vein thrombosis, who had fallen on her right shoulder. She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm. This was treated with an endovascular stent resulting in slightly improved motor function, but the significant residual deficit required subsequent rehabilitation to improve right upper limb function.

    Full Text Available Abstract Introduction Axillary artery injury is a rare but severe complication of fractures of the surgical neck of the humerus. Case presentation We present a case of axillary artery pseudoaneurysm secondary to such a fracture, in a 82-year-old white woman, presenting 10 weeks after the initial injury, successfully treated with subclavian to brachial reversed vein bypass together with simultaneous open reduction and internal fixation of the fracture. We discuss the use of a Javid™ shunt during combined upper limb revascularisation and open reduction and internal fixation of the fractured humerus. Conclusion This case highlights the usefulness of a Javid™ shunt, over other forms of vascular shunts, in prompt restoration of blood flow to effect limb salvage. It can be considered as a temporary measure whilst awaiting definitive revascularisation which can be performed following fracture fixation.

    Objective To evaluate subclavicular angiography with brachial-axillary artery externally and temporally occluded in depicting hemoptysis-related ectopic arteries originating from shoulder, neck and chest wall in the interventional treatment of hemoptysis. Methods A retrospective analysis of the medical records and angiograms of 103 patients who underwent transarterial procedures for hemoptysis was carried out. The arteries originating from the subclavicular arteries supplying the shoulder, the neck and the chest wall, ectopic bronchial arteries (EBA) as well as non bronchial systemic arteries (NBSA), were depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. The number and distribution of the responsible aberrant arteries were investigated. Results Of the hemoptysis-related arteries(n=372) depicted and embolized in the studies, 51.9% was normally-originated bronchial arteries(n=193),6.7% was ectopic bronchial arteries (n=25),41.4% was NBSA(n=154).Both anomalous and NBSA arising from subclavicular-axillary area(n=80) were accounted for 21.5% (80/372) of all aberrant arteries, and 44.7%(80/179) of all anomalous and NBSA (n=25+154=179).Of those arising from subclavicular-axillary arteries,56.3%(45/80) were found to be originated from the internal thoracic artery (n=45),98.2%(112/114)of responsible internal thoracic arteries and their distal branches were well depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. Conclusion Subclavicular-axillary artery is a very important vessel where EBA and NBSA originate. Subclavicular angiography with brachial-axillary artery externally and temporally occluded could help to determine the abnormal arteries in the region quickly. The method should be taken as a routine procedure for interventional treatment of hemoptysis.%目的 探讨肱-腋动脉体外临时阻断后行锁骨下动脉造影对显示肩颈-胸壁区咯血来源血

    The authors compared axillary skin temperatures (AT) measured with an infrared (IR) thermometer (Lightouch Neonate, Exergen Corp) with rectal temperatures (RT) in 16 newly born term infants under radiant warmers (RW) and in cribs. Twelve stable, growing premature infants in incubators were also studied. This new device may be useful because of safety and rapid results (1 second), but clinical accuracy is unknown. For term infants, mean (SD) RT-AT difference was 0.1 (0.48) degree C under RW and 0.25 (0.17) degree C 2 hours later in cribs. For premature infants in incubators the mean RT-AT difference was 0.09 (0.16) degree C. Axillary temperatures measured by IR thermometer approximate RT for newly born term infants in cribs and stable premature infants in incubators. For newly born term infants under RW, RT-AT differences vary more widely, limiting clinical usefulness in this setting. The device, the unique age of this population, and the RW environment may play a role. PMID:9924640

    Widespread use of screening mammography has resulted in a remarkable increase in the incidence (or detection rate) of ductal carcinoma in situ (DCIS). Axillary lymph node involvement in DCIS is reported to occur at a frequency of 1-12 per cent. Over the past few years, however, there has been increasing emphasis on axillary sampling, limited axillary dissection, and the potential role of sentinel lymph node biopsy. The clinical relevance of axillary lymph node biopsy or dissection remains unanswered. This retrospective analysis was performed on 171 patients who underwent treatment for DCIS at a tertiary care center over a period of 14 years. Clinical and tumor factors were evaluated, and the local, axillary, and systemic recurrence rates were noted. No axillary recurrences from the primary DCIS diagnosis were noted in the entire group of 171 patients. During a mean follow-up of 70 months, 10 patients (6%) developed recurrence in the ipsilateral breast. Six of these recurrences were in the form of DCIS, whereas, four recurred as invasive cancers. Nine patients developed a new primary (seven DCIS and two invasive) in the same breast but in a different quadrant. Two patients with ipsilateral invasive disease also developed systemic disease and eventually died of disease. During the same period, 10 patients (6%) developed DCIS, and seven patients (4%) developed invasive cancer in the contralateral breast. The data show that the risk of axillary recurrence in pure DCIS is, at most, extremely low and support the position that nodal sampling or dissection is unwarranted. PMID:15529841

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Full Text Available Introduction: Axillary breast is a common condition that leads to discomfort and cosmetic problems. Liposuction alone and open excision are two techniques used for treatment. Materials and Methods: This study assesses the results of treatment in 24 consecutive patients, operated between 2005 and 2015.All patients had Kajava class IV masses. Three were treated by liposuction alone, while 21 were treated by open axillaplasty with limited liposuction. Results: One patient treated by liposuction alone had to be re-operated for a residual lump, while with axillaplasty, no major complications were observed and the results were uniformly good. Discussion: Certain points of technique emerged as major determinants in obtaining the best results. In brief, these are: a limited skin excision; b placing elliptical incisions within the most lax, apical axillary skin, irrespective of the location of the lump; c raising skin flaps at the level of superficial fascia; dmeticulous dissection and preservation of the nerves, especially the second intercostobrachial; f judicious liposuction for eliminating dog ears and axillary sculpting only; g avoiding drains. Conclusion: Open axillaplasty with limited liposuction is the best way to minimise complications and produce good results.

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

    Hyperhidrosis and bromhidrosis were lately reported as novel side effects of laser-assisted removal of axillary hair. The goal of our study was to evaluate the reversibility of these two side effects. An observational, single-center cohort study included over a 30-month screening period 30 patients with newly reported hyperhidrosis and/or bromhidrosis related to axillary depilatory laser. After 26 weeks of follow-up, each patient was assessed for spontaneous reversibility. A 12-week duration treatment with topical aluminum chloride was evaluated in patients with persisting hyperhidrosis. Hyperhidrosis was assessed using the Hyperhidrosis Disease Severity Scale (HDSS). Spontaneous reversibility was observed in 20% of patients. In total, 23 out of 30 patients recovered normal axillary transpiration either spontaneously or after treatment. Mean HDSS score was significantly lower in the treated group. It appears that axillary hyperhidrosis and bromhidrosis, secondary to laser depilation, reverse either spontaneously or after using topical antiperspirant. PMID:23887660

    attempted CV catheters, 43 were placed successfully. In 2 cases the axillary vein could not be encountered by the puncture needle. Guide-wire placement did not succeed in 4 patients. One catheter was malpositioned in the ipsilateral internal jugular vein. Four inadvertent punctures of the axillary artery remained without sequelae after compression. No further puncture-related complications were observed. With high US intensity score the number of puncture attempts necessary for successful vein cannulation was lower. On the other hand, complications and puncture failure seemed to be more frequent in patients with lower US intensity scores. DISCUSSION. CV access via the axillary vein had a satisfying success rate (43/50) and proved to be a safe procedure in our ICU patients despite higher risk factors compared to a healthy population. Although ethical reasons did not allow a randomised comparison with the standard technique, location of the axillary vein by Doppler US is likely to improve cannulation results and reduce complications induced by "blind" needle probing. With a low US intensity score, the rate of successful punctures is lower and complication rates increase. In some patients, e.g., those with extended tumour operations involving the head and neck, CV access via the axillary vein may be of high clinical value.

  8. Axillary silicone lymphadenopathy secondary to augmentation mammaplasty

    2010-01-01

    Full Text Available We report a case involving a 45-year-old woman, who presented with an axillary mass 10 years after bilateral cosmetic augmentation mammaplasty. A lump was detected in the left axilla, and subsequent mammography and magnetic resonance imaging demonstrated intracapsular rupture of the left breast prosthesis. An excisional biopsy of the left axillary lesion and replacement of the ruptured implant was performed. Histological analysis showed that the axillary lump was lymph nodes containing large amounts of silicone. Silicone lymphadenopathy is an obscure complication of procedures involving the use of silicone. It is thought to occur following the transit of silicone droplets from breast implants to lymph nodes by macrophages and should always be considered as a differential diagnosis in patients in whom silicone prostheses are present.

    Full Text Available A young lady with residual polio, using axillary crutch since early childhood, presented with tingling, numbness and weakness in ulnar nerve distribution of five months duration. Ulnar motor conduction study revealed proximal conduction block near the axilla, at the point of pressure by the crutch while walking. Distal ulnar sensory conduction studies were normal but proximal ulnar sensory conduction studies showed absence of Erb′s point potential. These findings suggested the presence of conduction block in sensory fibers as well. Proper use and change of axillary crutch resulted in clinical recovery and resolution of motor and sensory conduction block.

    Full Text Available Background: The axillary lymph node stage is one of the single most important determinants in the prognosis of breast cancer patients. The disadvantages of the two previous methods used for evaluating axillary node metastasis, i.e., axillary lymph node dissection and sentinel lymph node biopsy, have directed researchers to investigate new techniques for this purpose. The aim of the current study was to evaluate the clinical usefulness of axillary ultrasonography in detecting axillary metastasis. Methods: This study was conducted during a 12-month period. The breast cancer cases included in this study were all clinically diagnosed as stages I and II, with no prior treatment to the axillary region by surgery and/or chemo-radiotherapy. Excluded from the study group were patients with palpable axillary lymph nodes, those who had major organ failure or concomitant malignancy. All included patients with non-palpable axillary lymph nodes underwent axillary ultrasound examination. An ultrasound- guided core needle biopsy was performed on patients with suspected metastasis. Results: There were 125 female patients with a mean age of 49.6 years included in this study. From these, 16 (12.8% cases had positive axillary sonographic findings. Pathologic evaluation of tissue specimens (taken by ultrasound-guided core needle biopsy in 10 (62.5% out of 16 patients were positive, and in the patient group of 6 (37.5% cases, studies were negative. Axillary ultrasonography had a sensitivity of 35.7%, specificity of 93.8%, positive predictive value of 62.5%, and negative predictive value of 83.5%. Conclusion: The axillary ultrasonogram is a reliable technique in the determination of axillary nodal metastatic involvement in breast cancer patients. By use of this method a significant amount of complications and costs related to the previous techniques can be avoided.

  19. LANGER’S AXILLARY ARCH AND ITS CLINICAL IMPLICATIONS

    Full Text Available Introduction: The axillary arch muscle of Langer is the most common anatomical variant of axillary musculature which is of clinical and surgical importance. It may lead to neurovascular compression syndrome in the cervicoaxillary region and can be misinterpreted while examining axilla and also impairs movements of shoulder joint. Observation: During routine dissection of axilla for undergraduate teaching, an unusual muscular slip in the left axilla was observed .The muscular slip was extending from lattisimus dorsi muscle to undersurface of pectoralis major muscle, arching over axillary vessels and cords of brachial plexus. Conclusion: The axillary arch may cause obstruction to axillary vessels and nerves and may be involved in thoracic outlet syndrome and shoulder instability. The knowledge of this muscular variant could help to minimize intraoperative complications related to surgeries in or nearby axilla such as mastectomy, breast reconstruction and axillary lymphadenectomy or lymph node biopsy.

    Full Text Available Abstract Aim To prove the possibility of axillary nerve conduction changes following shoulder subluxation due to hemiplegia, in order to investigate the usefulness of screening nerve conduction studies in patients with hemiplegia for finding peripheral neuropathy. Methods Forty-four shoulders of twenty-two patients with a first-time stroke having flaccid hemiplegia were tested, 43 ± 12 days after stroke onset. Wasting and weakness of the deltoid were present in the involved side. Motor nerve conduction latency and compound muscle action potential (CMAP amplitude were measured along the axillary nerve, comparing the paralyzed to the sound shoulder. The stimulation was done at the Erb's point whilst the recording needle electrode was inserted into the deltoid muscle 4 cm directly beneath the lateral border of the acromion. Wilcoxon signed rank test was used to compare the motor conduction between the sound and the paralytic shoulder. Mann-Whitney test was used to compare between plegic and sound shoulder in each side. Results Mean motor nerve conduction latency time to the deltoid muscle was 8.49, SD 4.36 ms in the paralyzed shoulder and 5.17, SD 1.35 ms in the sound shoulder (p Mean compound muscle action potential (CMAP amplitude was 2.83, SD 2.50 mV in the paralyzed shoulder and was 7.44, SD 5.47 mV in the sound shoulder (p p p = 0.003, 1-sided for amplitude, and patients with left paralyzed shoulder compared to patients with left sound shoulder (p = 0.011, 1-sided for latency, p = 0.001, 1-sided for amplitude, support the same outcomes. The electro-physiological changes in the axillary nerve may appear during the first six weeks after stroke breakout. Conclusion Continuous traction of the axillary nerve, as in hypotonic shoulder, may affect the electro-physiological properties of the nerve. It most probably results from subluxation of the head of the humerus, causing demyelinization and even axonopathy. Slowing of the conduction velocities of

    Full Text Available Chyle leak following axillary lymph node clearance is a rare yet important complication. The treatment of postoperative chyle fistula still remains unclear. Conservative management is the first line of treatment. It includes axillary drains on continuous suction, pressure dressings, bed rest, and nutritional modifications. The use of somatostatin analogue is well documented as a treatment for chylous fistulas after neck surgery. We present a case of chylous fistula after axillary surgery resolved with the use of octreotide.

  2. Occult breast carcinoma presenting as axillary metastases

    International Nuclear Information System (INIS)

    Purpose: Breast carcinoma presenting with axillary lymphadenopathy and no clinical or radiological evidence of a primary tumor is a rare presentation. We aimed to examine the management of the breast by observation, radiation therapy, or mastectomy. Methods and Materials: Departmental records from 1979 to 1996 of unknown primary presentations and cases of T0N1-2M0 breast carcinoma were reviewed to find cases of occult breast carcinoma presenting as axillary lymphadenopathy with no clinical or imaging evidence of a primary tumor. Results: There were 6047 presentations of breast carcinoma with 20 cases of occult breast carcinoma meeting the criteria. The breast was treated by observation in 6 cases, mastectomy in 2 cases, and radiotherapy to the intact breast in 12 cases. Eighty-three percent of patients (5 of 6 patients) who had observation of the breast had a local recurrence, compared to 25% who had radiotherapy to the intact breast (3 of 12 patients) and 0% who had a mastectomy (0 of 2 patients). The median recurrence-free survival was 7 months in patients who had observation of the breast, compared to 182 months in patients who had local treatment. Three of the 6 patients who underwent breast observation have died whereas 1 of the 14 who had local treatment have died, with a mean follow-up of 73 months. It was found that patients having observation of the breast had a poorer recurrence-free survival (p = 0.003) and overall survival (p = 0.05) compared to those having local treatment of the breast. Conclusions: Patients with such a presentation should have a complete physical examination, mammography, ultrasound, and MRI of the breasts. If there remains no evidence of a primary tumor, an axillary dissection should be carried out and the breast treated by radiotherapy or mastectomy. Observation of the breast is not a recommended option

    Eccrine porocarcinoma, a rare cutaneous malignant tumour accounts for a fraction of sweat gland tumours. This tumour is found to originate from the intraepithelial parts of the sweat glands. It commonly involves the lower extremities in elderly patients and carries an aggressive behaviour. Cutaneous and visceral metastasis can occur and hence prompt treatment is mandatory. Surgical excision is the mainstay of treatment modality. We hereby present a case of eccrine porocarcinoma in a 50-year-old male in the right axillary region presenting as a verrucous lesion.

    Not every axillary dermatitis is caused by an allergy against corresponding cosmetics (deodorants or anti-perspirants). This is shown in a 24-year-old man with an acute contact dermatitis in the left axilla. Sensitization probably developed against mercury salts due to the regular use of thermometers which were kept in a disinfecting solution containing phenylmercuric borate. The patient was in two hospitals for a check up before heart surgery and temperature was regularly measured in the left axilla. In both clincis phenylmercuric borate was used for desinfection of the thermometers. The sensitivity was proofed by positive patch tests.

    The skin of the axilla is cosmetically important with millions of consumers daily applying antiperspirant/deodorant products. Despite this, we know virtually nothing about axillary skin or how antiperspirant (AP) use impacts upon it. To characterize the axillary stratum corneum and determine whether this is a unique skin type, we have looked at stratum corneum composition and function, particularly its barrier properties, and compared it with other body sites. Transepidermal water loss (TEWL) and corneosurfametry (CSM) revealed a reduced barrier function in the axilla. HPTLC analysis of the stratum corneum lipids demonstrated statistically elevated levels of fatty acids, ceramides, and particularly cholesterol in the axilla. Both ceramide and cholesterol did not appear to change with depth, indicating that they were predominantly of stratum corneum origin. On the other hand, at least some of the fatty acid had a sebaceous origin. We hypothesized that the reduced barrier function might be owing to the changes in the crucial ceramide : cholesterol ratio. To address this, we used a combination of attenuated total reflectance-Fourier-transformed infrared spectroscopy (ATR-FTIR) with cyanoacrylate sampling. These results demonstrated more ordered lipid-lamellae phase behaviour in the axilla, suggesting that the elevated cholesterol might form crystal microdomains within the lipid lamellae, allowing an increase in water flux. Since an exaggerated application of antiperspirant had no effect upon the axilla barrier properties, it is concluded that this region of skin physiologically has a reduced barrier function.

    Removal of underarm hair is an intrinsic part of the care regimen for the majority of female consumers, with most using a wet shave with a disposable razor. However, little is known of the impact of shaving on axillary skin, and it is a particularly neglected area of research. To investigate this, we have studied the acute and chronic effects of shaving ultrastructurally, biochemically and functionally. A forearm patch test protocol was devised for antiperspirant (AP) product screening, which involved a pre-shave of the test site with a dry razor just prior to patching. Comparison of the irritation caused by a series of AP products confirmed that shaving leads to increased irritation consistent with enhanced sensitivity. The effect of regular shaving in the axilla was assessed in a 4-week in-use study with shaving either once a week or once a day, both combined with the application of an AP. Expert visual assessment of skin condition showed that more frequent shaving promoted a higher level of visible irritation. However, indirect measurement using corneosurfametry indicated no significant changes to the lipid barrier over the study period irrespective of shaving frequency. Nevertheless, digital images of the axillary skin after dry shaving show distinct opaque lines because of uplifting skin flakes with a corresponding increase in scaliness parameter. Moreover, histamine iontophoresis to assess skin sensitivity demonstrated a significant enhancement of histamine-induced itch and neurogenic flare.

  8. Axillary irradiation omitting axillary dissection in breast cancer: is there a role for shoulder-sparing proton therapy?

    Farace, P; Deidda, M A; Amichetti, M

    2015-10-01

    The recent EORTC 10981-22023 AMAROS trial showed that axillary radiotherapy and axillary lymph node dissection provide comparable local control and reduced lymphoedema in the irradiated group. However, no significant differences between the two groups in range of motion and quality of life were reported. It has been acknowledged that axillary irradiation could have induced some toxicity, particularly shoulder function impairment. In fact, conventional breast irradiation by tangential beams has to be modified to achieve full-dose coverage of the axillary nodes, including in the treatment field a larger portion of the shoulder structures. In this scenario, alternative irradiation techniques were discussed. Compared with modern photon techniques, axillary irradiation by proton therapy has the potential for sparing the shoulder without detrimental increase of the medium-to-low doses to the other normal tissues.

    2006-04-01

    Extra-axillary sentinel lymph nodes can only be detected if radioactive tracer is used and pre-operative scans are carried out. The presence of metastatic sentinel lymph nodes in most extra-axillary sites will upstage patients if the ipsilateral axillary sentinel lymph node is normal. Paradoxically, the presence of metastatic sentinel lymph nodes in the contralateral axilla has the potential to prevent upstaging to stage IV, but only if detected as a sentinel node at the initial surgery rather than as a systemic recurrence at some later time. We describe a case of bilateral axillary sentinel lymph nodes detected by pre-operative lymphoscintigraphy in a patient with a medial quadrant breast cancer and discuss the possible implications of such a finding.

    Full Text Available Background: Axillary post-burn scar contracture is a challenging problem to the reconstructive surgeon owing to the wide range of abduction that should be achieved. The aim of this paper was to highlight the various options used in managing axillary contractures in our hospital. Materials and Methods: This is a retrospective hospital-based study of axillary contractures managed at Safdarjung Hospital (a tertiary care hospital from 2009 to 2013.The study consisted of 44 patients from all age group and both sex included in it. Patients with a bilateral axillary contracture were excluded. Axillary contracture was released and resurfaced using split skin graft and/or with different types of flaps including the propeller flap, parascapular flap. All the reconstructed cases were followed-up for a period of 12 months. Assessment was done on the basis of functional and aesthetic outcome. Results: Forty-four patients consisting of 25 males and 19 females presented with axillary contractures that involved 44 axillae. The mean age of the study group was 17.1 years. Injuries involved the anterior axillary fold in 8 (18.18%, posterior fold in ten (22.72%, both folds and axillary fossa in 14 (31.81% and both folds plus part of the chest wall and arm (sparing the axillary fossa in 12 (27.27% axillae. Surgical treatment included split-thickness skin graft in 15 (34.1%, local skin flaps in 4 (9.1%, Z-plasties in 4 (9.1%, parascapular flaps in 3 (6.82%, while propeller flaps in 12 (27.27% and square flap were used in 6 (13.64% patients. The percentage of improvement in abduction had a mean of 156°. The functional and aesthetic results were satisfactory. Conclusion: The choice of surgical procedure for reconstruction of post-burn axillary contractures can be made according to the pattern of scar contracture and the state of the surrounding skin. The choice of a flap should have priority over the skin graft because of the superior functional and aesthetic results

    Studies of apical dominance have benefited greatly from two-branch assays in pea and bean,in which the shoot system is trimmed back to leave only two active cotyledonary axillary branches.In these two-branch shoots,a large body of evidence shows that one actively growing branch is able to inhibit the growth of the other,prompting studies on the nature of the inhibitory signals,which are still poorly understood.Here,we describe the establishment of two-branch assays in Arabidopsis,using consecutive branches on the bolting stem.As with the classical studies in pea and bean,these consecutive branches are able to inhibit one another's growth.Not only can the upper branch inhibit the lower branch,but also the lower branch can inhibit the upper branch,illustrating the bi-directional action of the inhibitory signals.Using mutants,we show that the inhibition is partially dependent on the MAX pathway and that while the inhibition is clearly transmitted across the stem from the active to the inhibited branch,the vascular connectivity of the two branches is weak,and the MAX pathway is capable of acting unilaterally in the stem.

  16. Experimental characterization of axillary/underarm interface pressure in swing-through crutch walking

    Directory of Open Access Journals (Sweden)

    James Borrelli, PhD

    2013-05-01

    Full Text Available Supporting weight on the upper support of crutches is not recommended because it can lead to axillary nerve damage. Despite this warning, improper axillary loadings may still occur because of a lack of arm strength or fatigue. It is generally accepted that improper use of conventional axillary crutches contributes to axillary nerve damage, but surprisingly there are no studies characterizing axillary support/underarm configurations. In this study, we compared traditional and horizontal axillary support designs by measuring various biomechanical parameters on the axillary support during a swing-through gait while supporting weight on the axillary support. Subjects found the axillary support that remains horizontal to be more comfortable than the axillary support of axillary crutches. The higher perceived comfort may be attributed to the lower force and contact area, both average and maximum, developed on the horizontal axillary support and/or shorter excursion of the position of the center of force during a stride. These findings suggest that avoiding all weight bearing on the axillary support may be an overly conservative recommendation for supports that remain horizontal. Individuals with insufficient arm strength may benefit by considering this type of support, but because further study is needed, a physical therapist should be consulted.

    2014-01-01

    Axillary staging of patients with early-stage breast cancer is essential in the treatment planning. Currently such staging is intraoperatively performed, but there is a tendency to seek a preoperative and less invasive technique to detect lymph node metastasis. Ultrasonography is widely utilized for this purpose, many times in association with fine-needle aspiration biopsy or core needle biopsy. However, the sonographic criteria for determining malignancy in axillary lymph nodes do not present significant predictive values, producing discrepant results in studies evaluating the sensitivity and specificity of this method. The present study was aimed at reviewing the literature approaching the utilization of ultrasonography in the axillary staging as well as the main morphological features of metastatic lymph nodes.

    Full Text Available Superficial brachial artery is one of the major variations of the arterial pattern in the upper limb. During routine anatomical dissection in our department, we observed a case of unilateral double brachial artery in a formalin-fixed female cadaver.Left axillary artery entered into the anterior region of the arm, where it branched into two brachial arteries – the superficial brachial artery (SBA, which was longer, tortuous and with a smaller caliber, and the brachial artery (BA, which was placed deep and medially. In the cubital fossa, covered with an aponeurosis of the biceps brachii muscle, both brachial arteries were connected with an anastomotic vessel. Under this anastomotic branch, in the forearm, SBA continued as the radial artery, whereas BA continued as the ulnar artery.Variations of the arterial pattern in the upper limb are undoubtedly of interest to the anatomists as well as to the clinicians.

With improvements in adjuvant therapy, routine axillary treatment may no longer offer any overall advantage. Objectives To assess the short and long term benefits and adverse effects of routine axillary treatment (axillary lymph node clearance or axillary radiotherapy for patients with lymph node positive early-stage breast cancer. Methods/Design Criteria for potentially eligibility for the study will be that the participants are men and women with early breast cancer and lymph nodes with metastasis. The study compares either axillary treatment with no axillary treatment, or axillary node clearance with axillary radiotherapy, and the study is a randomized trial. Primary outcomes are axillary recurrence, disease-free and overall survival. Secondary outcomes include breast or chest wall recurrence, distant metastasis, time to axillary recurrence, axillary recurrence-free survival, arm morbidity, quality of life and health economic costs. The search strategy will include the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and WHO International Clinical Trials Registry Platform (ICTRP search portal. Two independent reviewers will assess studies for inclusion in the review, assess study quality and extract data. Characteristics of included studies will be described. Meta-analysis will be conducted using ReVman software. Comment This review addresses an important clinical question, and results will inform clinical practice and health care policy.

    Full Text Available Background: Primary hyperhidrosis is characterized by excessive sweating beyond physiological needs. It is a common disease (incidence 2.8% that causes intense discomfort for patients. In the last decade, advantages of Single-Incision Thoracoscopic Sympathectomy have become clear, particularly in decreasing morbidity of sympathectomy. Patients and methods: From January 2010 to December 2012, 39 patients (29 females and 10 males with primary palmar or axillary hyperhidrosis were treated by thoracoscopic sympathectomy. The age ranged from 18 to 40 years with a mean of 26.28 years. We used single incision thoracoscopic electrocoagulation through 10 mm incision for thoracic sympathetic chain (T2–T4. Results: The mean follow-up was 23.6 ± 14.2 months (range = 4–24 months. A total of 97.42% of patients were satisfied with the results. A total of 72.5% of patients had cure, one patient (2.5% and another patient (2.5% presented with recurrent axillary hyperhidrosis. The morbidity was 10.2% with no mortality. Percentage of compensatory sweating and gustatory sweating were 5.1% (p = .353 and 2.5% (p = .552, respectively. The result of sympathectomy in patients with both palmar and axillary hyperhidrosis was significantly better (17, 43.58% compared to palmar type (14, 35.89% or axillary type (7, 17.94%. Conclusion: Thoracoscopic sympathectomy is a simple, safe, and cost-effective therapy with good results and low complications.

  3. Axillary Bud Proliferation Approach for Plant Biodiversity Conservation and Restoration

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Due to mainly human population pressure and activities, global biodiversity is getting reduced and particularly plant biodiversity is becoming at high risk of extinction. Consequently, many efforts have been deployed to develop conservation methods. Because it does not involve cell dedifferentiation of differentiated cells but rather the development and growth of new shoots from preexisting meristems, the axillary bud proliferation approach is the method offering least risk of genetic instability. Indeed, meristems are more resistant to genetic changes than disorganized tissues. The present review explored through the scientific literature the axillary bud proliferation approach and the possible somaclonal variation that could arise from it. Almost genetic stability or low level of genetic variation is often reported. On the contrary, in a few cases studied to date, DNA methylation alterations often appeared in the progenies, showing epigenetic variations in the regenerated plants from axillary bud culture. Fortunately, epigenetic changes are often temporary and plants may revert to the normal phenotype. Thus, in the absence of genetic variations and the existence of reverting epigenetic changes over time, axillary bud culture can be adopted as an alternative nonconventional way of conserving and restoring of plant biodiversity.

    We describe a case of right mammary homolateral recurrence with controlateral axillary invasion. The absence of occult involvement of the left breast was confirmed by MRI. A subsequent thoraco-abdomino-pelvic scan and bone scintigraphy did not reveal any metastases. Lymphoscintigraphy of the right breast, after periareolar injection, revealed lymphatic drainage from the right breast into the left contralateral axillary lymph node. Because of the changes in axillary drainage after mammary and axillary surgery observed by lymphoscintigraphy, contralateral axillary involvement could be considered as locoregional disease in the same way as homolateral lymph node involvement.

    1989-01-01

    Stenosis or occlusion of the subclavian vein can cause incapacitating upper extremity swelling and venous hypertension in the patient with an arteriovenous (AV) access. A case of subclavian vein occlusion is reported that was treated with internal jugular-axillary vein bypass. This procedure resulted in salvage of the access and rapid resolution of the associated upper extremity swelling. It was concluded that jugular-axillary vein bypass should be considered in patients who have massive upper extremity edema resulting from a functioning AV access and ipsilateral subclavian vein occlusion. Patients undergoing creation of an AV access who have had previous temporary subclavian catheters or previous early failure of an AV access should have phlebography before surgery.

    Chylous leakage after mastectomy & axillary clearance is a rare complication. The incidence is less than 0.5%. Anatomical variations in the termination of thoracic duct can occur, rendering it susceptible to injury during axillary dissection. Most chyle leaks in the axilla are managed through conservative measures. Surgical intervention is required in high output chylous leaks. We encountered a case of chylous leak post mastectomy with axillary clearance, which was successfully treated conservatively.

    Perlmutter, G S; Apruzzese, W

    1998-11-01

    Axillary nerve injuries are some of the most common peripheral nerve injuries in athletes who participate in contact sports. Resulting deltoid muscle paralysis is secondary to nerve trauma which occurs following shoulder dislocation or a direct blow to the deltoid muscle. Compression neuropathy has been reported to occur in quadrilateral space syndrome as the axillary nerve exits this anatomic compartment. The axillary nerve is also extremely vulnerable during any operative procedure involving the inferior aspect of the shoulder, and iatrogenic injury to the axillary nerve remains a serious complication of shoulder surgery. Accurate diagnosis of axillary nerve injury is based on a careful history and physical examination as well as an understanding of the anatomy of the shoulder and the axillary nerve in particular. Inspection, palpation and neurological testing provide the bases for diagnosis. A clinically suspected axillary nerve injury should be confirmed by electrophysiological testing, including electromyography and nerve conduction studies. During the acute phase of injury, the athlete should be rested and any ligamentous or bony injury should be treated as indicated. Patients should undergo an extensive rehabilitation programme emphasising active and passive range of motion as well as strengthening of the rotator cuff, deltoid and periscapular musculature. Shoulder joint contracture should be avoided at all costs as a loss of shoulder mobility may ultimately affect functional outcome despite a return of axillary nerve function. If no axillary nerve recovery is observed by 3 to 4 months following injury, surgical exploration is indicated. Athletes who sustain injury to the axillary nerve have a variable prognosis for nerve recovery, although the return of function of the involved shoulder is typically good to excellent. We recommend that athletes who sustain axillary nerve injury may return to contact sport participation when they achieve full active range of

    Objective:Open thoracic sympathectomy has been established as a routine treatment for patients with primary hyperhidrosis. Recently, thoracoscopic techniques have allowed surgeons to offer these patients a permanent solution with minimal surgical trauma. Methods:From June 1996 to July 2002, 78 thoracoscopic sympathectomies(TS) were performed. There were 28 males and 50 females with a mean age of 22.4 years (range, 14 to 48 years). The procedures were performed with the patients under general anesthesia using a double- lumen endotracheal tube. In palmar hyperhidrosis the second thoracic sympathetic oanglia are destroyed by electrocautery. In axillary hyperhidrosis the second to fourth oanglion are cut off. Each lung was reinflated on completion of the sympathectomy, and residual pneumothorax aspirated before closure of the incisions. No placement of chest tubes was performed in the operating. Results:All sympathectomies were completed thoracoscopically. The symptoms disappeared completely in all patients immediately after the operation. Their hands were dry and warm when they waked up from anaesthesia. There was no surgical mortality. Median operation time for a bilateral procedure is 28 min. (range, 8 - 90 min). The average hospital stay was 5.5 days. The mean follow- up time was 43.8 months (range, 3 - 73months). Compensatory hyperhidrosis was found in 41.03% (32/78) of patients, but the symptoms were not serve enough to interfere with lifestyle, and were not required further treatment. In all 78 patients had a satisfactory result, without recurrence of palmar or axillary hyperhidrosis. Conclusions: Thoracoscopic sympathectomy is the most effective and minimally invasive treatment for palmar and axillary hyperhydrosis.

    To determine objective criteria for ultrasonography (US) appearance in the diagnosis of abnormal axillary lymph nodes (ALNs) and to assess retrospectively their accuracy in preoperative staging of patients with Breast Imaging Reporting and Data System (BI-RADS) Category 5 breast lesion. US-guided axillary fine-needle aspiration biopsy (FNAB) was performed for preoperative staging of BI-RADS Category 5 lesions in breast cancer patients seen at the Ottawa Regional Women's Breast Health Centre. Retrospectively, ALN morphology was classified into 3 categories based on US appearance: mass-like appearance, focal nodular cortical thickening (FNCT), and diffuse cortical thickening (DCT), the latter 2 with fatty hilum preservation and cortical thickening greater than 2 mm. Cytologic results from the FNAB were compared with axillary lymph node dissection (ALND) or sentinel lymph node procedure (SLNP), when available. Retrospective image-based classification was performed blind to pathology results and analyzed with Pearson's correlation coefficient, receiver operating characteristic (ROC) curves, and chi-square and Hosmer-Lemeshow tests against the cytologic ground truth. Eighty-six ALNs in 84 patients were sampled with an 18-gauge needle under US guidance. The number of passes per sample was related to adequate sampling of positive ALNs having mass-like morphology but not DCT or FNCT (p < 0.001). The most frequent morphologic presentation of the 86 ALNs was mass-like appearance of lymph nodes (45%), followed by DCT (35%) and FNCT (20%). Metastatic involvement was found in 34 (87%) of 39 ALNs that were mass-like, in 9 (53%) of 17 ALNs with FNCT, and in 9 (30%) of 30 ALNs with DCT. The kappa agreement between FNAB and ALND or SLNP was 0.64 for mass-like lymph nodes, 0.7 for lymph nodes with DCT, and 1.0 for FNCT. Overall sensitivity and specificity were 94% and 89%, respectively, with a positive predictive value of 97% and negative predictive value of 80%. Using a 2

    Full Text Available Proliferative trichilemmal tumor is a skin neoplasm derived from a hair follicle. It is more frequent in women and its prevalance increases after the 6th decade. Although the most frequent site is mentioned as hairy skin, it can also be detected on the neck, face, ear, hand and vulva. In this case, we discussed a 49 year old female patient presenting with a mass at right axillary region. The result of biopsy demonstrated that it was a proliferative trichilemmal tumor. The patient was re-operated due to the presence of surgical border positivity. The patient, who had no adjuvant treatment, is under follow-up and in remission.

    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.

    In this study an unusual combination of arterial, venous and neural variations discovered during dissection of cervical, axillary and brachial area of a cadaver is described. Variations are thoroughly described and literature is briefly reviewed. Lateral cord of brachial plexus was not formed; Eight Cervical root divided into anterior and posterior division before uniting with First Thoracic root and Upper Trunk was unusually short. Axillary artery gave origin to a superficial brachial artery and then continued as deep brachial artery. Multiple variations in typical axillary artery branches were present including existence of inferior pectoral artery. Cephalic vein was absent. A variety of interventions, from relative simple as central venous catheter placement to most complicated as brachial plexus injury repair demand thorough knowledge of area's regional anatomy. Familiarity with anatomic variations allows more precise and careful interventions. Research on these variations is valuable for anatomists and embryologists but also for clinicians because it may provide useful information for non - typical cases but also helps in raising a high level of suspicion.

    We report the utility of office-based, nonimaged guided fine needle aspiration of palpable axillary lymph nodes in breast cancer patients. We examine the sensitivity and specificity of this procedure, and examine factors associated with a positive fine needle aspiration biopsy result. Although the utility of ultrasound-guided fine needle aspiration biopsy (FNA) of axillary lymph nodes is well established, there is little data on nonimage guided office-based FNA of palpable axillary lymphadenopathy. We investigated the sensitivity and specificity of nonimage-guided FNA of axillary lymphadenopathy in patients presenting with breast cancer, and report factors associated with a positive FNA result. Retrospective study of 94 patients who underwent office-based FNA of palpable axillary lymph nodes between 2004 and 2008 was conducted. Cytology results were compared with pathology after axillary sentinel node or lymph node dissection. Nonimage-guided axillary FNA was 86% sensitive and 100% specific. On univariate analysis, patients with positive FNA cytology had larger breast tumors (p = 0.007), more pathologic positive lymph nodes (p benefits select patients, permitting avoidance of axillary ultrasound, sentinel lymph node biopsy, or delay in receiving neoadjuvant therapy. This results in time and cost savings for the health care system, and expedites definitive management. PMID:22098412

  3. Early experiences of breast-conservation treatment without axillary dissection for breast cancer patients with clinically-negative axillary nodes

    International Nuclear Information System (INIS)

    Nineteen patients with breast cancer who had clinically negative axillary nodes were treated with breast-conservation treatment, consisting of lumpectomy, irradiation, endocrine therapy (tamoxifen), and adjuvant chemotherapy. They were all women, whose ages ranged from 35 to 84 years with a mean of 53.8 years. Preoperative UICC staging was I in 10 patients, IIA in 8, and IIB in one; and postoperative staging was I in 7 and IIA in 12. Among evaluable 13 patients, 5 (38.5%) had microscopically positive margin. Radiation therapy was started within two to three weeks after breast-conserving surgery. Patients received irradiation to the ipsilateral breast and chest wall, including the ipsilateral axillary region, using opposed tangential fields to a dose of 4400 cGy at 275 cGy per fraction. Boost irradiation using an electron beam was delivered with a dose of 1000 cGy in 2 fractions in the last week of radiotherapy in all patients. In addition, adjuvant chemotherapy (cyclophosphamide, pirarubicin or epirubicin, 5-fluorouracil) and endocrine therapy (tamoxifen) were given. With a mean follow up of 20.7 months, one patient aged 80 died of cardiac failure and pneumonia without evidence of breast cancer progression. The other 18 patients are alive without either local failure or distant metastases. Cosmetic evaluation showed each 9 patients to be 'excellent' or 'good'. No patients have serious adverse effects as of this writing. Although the follow-up period is short and the number of patients is limited, the preliminary results of breast-conservation treatment for axillary negative breast cancer seem to be sufficiently good.

    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.

    2016-02-01

    Full Text Available One distinctive feature of plant post-embryonic development is that plants can undergo reiterative growth and continuous organogenesis throughout their lifetimes. Axillary meristems in leaf axils play a central role in this growth and differences in meristem initiation and development produce the diversity of plant architecture. Studies in the past fifteen years have shown that several transcription factors and phytohormones affect axillary meristem initiation. In this review, we highlight recent research using systems biology approaches to examine the regulatory hierarchies underlying axillary meristem initiation and the role of auxins and cytokinins in axillary meristem initiation and development. This research revealed a developmental mechanism in which phytohormone signals act with a gene regulatory network containing multiple transcription factors to contribute to the initiation of axillary meristems.

    Continuous interscalene brachial plexus blockade can provide anesthesia and analgesia in the shoulder region. Difficulty accessing the interscalene space and premature displacement of interscalene catheters may preclude their use in certain situations. We present two case reports in which a catheter was advanced from the axilla along the brachial plexus sheath to the interscalene space to provide continuous cervicobrachial plexus analgesia. In the first case report, previous neck surgery made the anatomic landmarks for performing an interscalene block very difficult. An epidural catheter was advanced from the axillary brachial plexus sheath to the interscalene space under fluoroscopic guidance. This technique provided both intraoperative analgesia for shoulder surgery as well as 24-hour postoperative analgesia by an infusion of 0.125% bupivacaine. In the second case report, a catheter was inserted in a similar fashion from the axillary to the interscalene space to provide 14 days of continuous analgesia in the management of complex regional pain syndrome. We have found that this technique allows us to secure the catheter more easily than with the traditional interscalene approach and thus prevents premature dislodgment. This approach may be a suitable alternative when either an interscalene or an infraclavicular catheter may not be inserted. PMID:11090734

    The use of underarm cosmetics is common practice in the Western society to obtain better body odor and/or to prevent excessive sweating. A survey indicated that 95 % of the young adult Belgians generally use an underarm deodorant or antiperspirant. The effect of deodorants and antiperspirants on the axillary bacterial community was examined on nine healthy subjects, who were restrained from using deodorant/antiperspirant for 1 month. Denaturing gradient gel electrophoresis was used to investigate the individual microbial dynamics. The microbial profiles were unique for every person. A stable bacterial community was seen when underarm cosmetics were applied on a daily basis and when no underarm cosmetics were applied. A distinct community difference was seen when the habits were changed from daily use to no use of deodorant/antiperspirant and vice versa. The richness was higher when deodorants and antiperspirants were applied. Especially when antiperspirants were applied, the microbiome showed an increase in diversity. Antiperspirant usage led toward an increase of Actinobacteria, which is an unfavorable situation with respect to body odor development. These initial results show that axillary cosmetics modify the microbial community and can stimulate odor-producing bacteria. PMID:25077920

The ICBN and one of its branches were surrounding the termination of an alar thoracic artery. These peripheral neural connections of the ICBN with the branches of the medial cord can be a cause of sensory impairment during axillary procedures done for mastectomy or exploration of long thoracic nerves. The alar thoracic artery found in relation to the ICBN could further be a cause of vascular complications during such procedures.

The alar thoracic artery found in relation to the ICBN could further be a cause of vascular complications during such procedures.

    Axillary evaluation in women with ductal carcinoma in situ (DCIS) is increasing; however, this may introduce additional morbidity with unclear benefit. Our objective was to examine the morbidity and mortality associated with axillary evaluation in DCIS. We conducted a retrospective cohort study of 10,504 women aged 65-90 years with DCIS who underwent breast conserving surgery between 2002 and 2012 using SEER-Medicare database. Patients were categorized by receipt of axillary evaluation with either sentinel lymph node biopsy (SLNB) or axillary node dissection (ALND). We determined the incidence of lymphedema treatment as defined by diagnostic and procedural codes, as well as 10-year breast cancer-specific and all-cause mortality. 18.3 % of those treated with BCS and 69.4 % of those treated with mastectomy had an axillary evaluation. One year after treatment, 8.2 % of women who had an axillary evaluation developed lymphedema, compared to 5.9 % of those who did not. In a multivariable Cox proportional hazard model, the incidence of lymphedema was higher among those who underwent axillary evaluation (HR 1.22, 95 % CI 1.04-1.45). Overall 10-year breast cancer-specific survival was similar between both groups (HR 0.83, 95 % CI 0.40-1.74). Only 44 (0.40 %) women died of breast cancer; receipt of axillary evaluation did not alter overall survival. Axillary evaluation is commonly performed in women with DCIS, especially those undergoing mastectomy. However, women who receive an axillary evaluation have higher rates of lymphedema, without breast cancer-specific or overall survival benefit. Efforts should be made to determine the population of women with DCIS who benefit from this procedure. PMID:27365080

    In the absence of distant disease simultaneous skin cancer metastasis to neck and axillary lymph nodes necessitates both an axillary and neck en block lymphadenectomy. A combined ipsilateral neck and axillary lymph node dissection should involve an in-continuity dissection through the cervicoaxillary canal for optimal lymphatic and oncological clearance. Review of the literature reveals little published instruction on the procedure since the radical surgery performed by Bowden over 50 years ago. We present 4 cases where ipsilateral axillary and neck lymph node dissections were performed for metastatic melanoma and a case of apical axillary node dissection via a neck incision approach. Our surgical tips include performing apical axillary node dissection via the neck incision and consideration of clavicular osteotomy or clavicular excision. A transclavicular approach was taken in one patient who had an excellent functional outcome after a plate and screw fixation. One elderly patient required a middle third claviculectomy which reduced shoulder elevation but was not associated with functional impairment. We conclude the surgery is safe and associated with the usual morbidity ascribed with either an axillary or neck dissection undertaken in isolation. However, patients have a significant risk of disease relapse as would be expected due to the duel metastatic sites, multiple lymph node and neck involvement which are known to be independent poor prognostic factors on melanoma survival and relapse.

    Radiographic demonstration of mediastinal lymphadenopathy is important for the diagnosis of pulmonary tuberculosis (PTB). Plain radiographs are unreliable for this and CT, which is relatively more expensive and carries a high radiation burden, remains the gold standard. No studies correlating the presence of axillary with mediastinal lymphadenopathy have been reported. Such a correlation would allow for clinical or ultrasound diagnosis of PTB via the axilla. To correlate the presence of axillary lymphadenopathy with mediastinal lymphadenopathy in children with suspected PTB. CT scans were performed and reviewed in 100 children (prospectively recruited) with suspected PTB. The axilla and mediastinum were reviewed separately by covering the non-relevant sections on the CT scans prior to reading. Only nodes greater than 1 cm were regarded as pathological. Mediastinal lymphadenopathy was present in 46% of children; 70% had lymphadenopathy in either axilla. Bilateral axillary lymphadenopathy was identified in 47%. Axillary lymphadenopathy showed a sensitivity of 74% and a specificity of 33% for the presence of mediastinal adenopathy. Bilateral axillary adenopathy had a sensitivity of 50% and a specificity of 56%. Axillary lymphadenopathy has a moderate sensitivity and low specificity for the presence of mediastinal and hilar lymphadenopathy in children with suspected PTB. Further research should be aimed at correlating ultrasound-detected axillary lymphadenopathy with FNA results in children. (orig.)

    To investigate the coverage of axillary lymph node with tangential breast irradiation fields by using virtual lymph node (LN) analysis. Forty-eight women who were treated with whole breast irradiation after breast-conserving surgery were analyzed. The axillary and breast volumes were delineated according to the Radiation Therapy Oncology Group (RTOG) contouring atlas. To generate virtual LN contours, preoperative fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scans with identifiable LN were fused with the CT scans, and the virtual LN contour were delineated on the CT. The median level I and II axillary volume coverage percentages at the VD95% line were 33.5% (range, 5.3% to 90.4%) and 0.6% (range, 0.0% to 14.6%), respectively. Thirty-one LNs in 18 patients were delineated (26 in level I and 5 in level II). In the level I axilla, 84.6% of virtual LNs were encompassed by the 95% isodose line. In the level II axilla, by contrast, none of the virtual LNs were encompassed by the 95% isodose volumes. There was a substantial discrepancy between the RTOG contouring atlas-based axillary volume analysis and the virtual LN analysis, especially for the level I axillary coverage. The axillary volume coverage was associated with the body mass index (BMI) and breast volume. The tangential breast irradiation did not deliver adequate therapeutic doses to the axillary region, particularly those in the level II axilla. Patients with small breast volumes or lower BMI showed reduced axillary coverage from the tangential breast fields. For axillary LN irradiation, individualized anatomy-based radiation fields for patients would be necessary.

    Mid-line sternotomy is the routine approach for surgical repair of congenital heart diseases. However, its noticeable scar is a constant reminder of having undergone heart surgery. Several alternative approaches have been developed for simple cardiac conditions to hide the scar. Our series, consisting of 26 patients with axillary closure of atrial septal defect, is presented. The median age was 5.45 years (range 3-13), and median weight was 19.84 Kg. (range 13-37). The defect was closed directly in 13 cases, and with an autologous pericardial patch in the other 13. The number of surgical steps and time taken were the same as in median sternotomy. Functional recovery, intensive care unit stay, and hospital discharge were also standard. The cosmetic result, assessed both by patients and relatives, was excellent. PMID:23462094

    Full Text Available Establishment of accurate axillary lymph node status is of essential importance in determining both prognosis and the potential need for adjuvant therapy in patients with invasive breast cancer. Axillary lymph node heterotopias can in some cases result in overdiagnosis of metastatic disease. Nodal endosalpingiosis is perhaps the least commonly reported type of axially lymph node heterotopia. We herein illustrate a case in which second opinion pathologic interpretation combined with ancillary immunohistochemical studies allowed for a specific diagnosis of axillary nodal müllerian-type inclusions, confirming ypN0 staging and resulting in appropriate disease management and prognostication.

    Full Text Available Background: Body temperature measurement is a crucial clinical assessment in the care of an acutely ill child, especially the under fives. Most temperature measurements in our hospital are done from the axilla. Objective: To study the relationship between temperatures taken in the axilla with those taken in the rectum in febrile and afebrile children less than 5 years. Materials and Methods: Rectal and axillary temperatures were taken concurrently in 400 febrile and 400 afebrile children aged less than 5 years using mercury-in-glass thermometers. Result: The rectal temperature measurements ranged from 38.0 to 41.4°C and 36.4 to 37.9°C in the febrile and afebrile groups of children respectively while the axillary temperatures ranged from 36.7 to 41.0°C and 35.9 to 37.5°C in the febrile and afebrile groups of children, respectively. There were significant differences between the temperatures measured at the two sites in all the age groups studied. There was good positive correlation between the rectal and axillary temperatures. A linear relationship between axillary and rectal temperatures was derived using the simple regression analysis. The equation is: rectal temperature = 0.94×axillary temperature+2.92. Conclusion: Although there′s good correlation between axillary and rectal temperatures, significant difference exits between them that cannot be explained by the addition of any single value or any particular equation.

    Full Text Available During routine dissection in our department, multiple arterial variations were observed in a cadaver. The following arterial variations are present. They are, superficial brachioulnar artery, which originated at the level of junction of upper and middle th ird of arm. It runs a superficial course anterior to median nerve in the arm and terminates in the formation of superficial palmar arch. The brachial artery terminated as radial and common interosseous artery. Subscapular artery and circumflex humeral arte ry arose as a common trunk from the third part of axillary artery. The circumflex humeral artery later divides into anterior circumflex humeral and posterior circumflex humeral arteries. The right common carotid artery bifurcated into internal carotid arte ry anteromedially and external carotid artery posterolaterally at the level of upper lamin a of th yroid cartilage. A proper knowledge of variations in the arterial pattern is a must for a good treatment outcome, especially in the fields like vascular surge ry, reconstructive surgery, cardiac surgery, angiogram, arterial cannulation, arterio - venous fistula for renal dialysis. etc.

    Background Axillary lymph node metastasis is a very important metastatic pathway in breast cancer and its accurate detection is important for staging tumour and guiding therapy. However, neither the accuracy of routine detection of lymph node in surgical specimens nor the significance of minute lymph node with metastases in breast cancer is clear. A modified method for conveniently detecting minute lymph node in specimens of axillary dissections in patients with breast cancer was used to analyze their influence on staging breast cancer.Methods Lymph nodes in fresh, unfixed, specimens of axillary dissections from 127 cases of breast cancer were detected routinely. Then the axillary fatty tissues were cut into 1 cm thick pieces, soaked in Carnoy's solution for 6 to 12 hours, taken out and put on a glass plate. Minute lymph nodes were detected by light of bottom lamp and examined by routine pathology.Results Lymph nodes (n= 2483, 19.6±8.0 per case) were found by routine method. A further 879 lymph nodes up to 6 mm (781 < 3 mm, 6.9±5.3 per case, increasing mean to 26.5±9.7) were found from the axillary tissues after soaking in Carnoy's solution. By detection of minute lymph nodes, the stages of lymph node metastasis in 7 cases were changed from pathological node (pN) stage pN0 to pN1 in 4 cases, from pN1 to pN2 in 2 and from pN2 to pN3 in 1.Conclusions The accurate staging of axillary lymph node metastasis can be obtained routinely with number of axillary lymph nodes in most cases of breast cancer. To avoid neglecting minute lymph nodes with metastases, small axillary nodes should be searched carefully in the cases of earlier breast cancer with no swollen axillary nodes. Treatment with Carnoy's solution can expediently detect minute axillary nodes and improve the accurate staging of lymph nodes in breast cancer.

    Full Text Available Background: Postoperative pain after breast cancer surgery is not uncommon. Narcotic based analgesia is commonly used for postoperative pain management. However, the side-effects and complications of systemic narcotics is a significant disadvantage. Different locoregional anesthetic techniques have been tried including, single and multiple levels paravertebral block (PVB, which seems to have a significant reduction in immediate postoperative pain with fewer side-effects. The aim of this study was to compare unilateral multiple level PVB versus morphine patient-controlled analgesia (PCA for pain relief after breast cancer surgery with unilateral lumpectomy and axillary lymph nodes dissection. Materials and Methods: Forty patients scheduled for breast cancer surgery were randomized to receive either preoperative unilateral multiple injections PVB at five thoracic dermatomes (group P, 20 patients or postoperative intravenous PCA with morphine (group M, 20 patients for postoperative pain control. Numerical pain scale, mean arterial pressure, heart rate, Time to first analgesic demand, 24-h morphine consumption side-effects and length of hospital stay were recorded. Results: PVB resulted in a significantly more postoperative analgesia, maintained hemodynamic, more significant reduction in nausea and vomiting, and shorter hospital stay compared with PCA patients. Conclusion: Multiple levels PVB is an effective regional anesthetic technique for postoperative pain management, it provides superior analgesia with less narcotics consumption, and fewer side-effects compared with PCA morphine for patients with breast cancer who undergo unilateral lumpectomy, with axillary lymph nodes dissection.

    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.

    2016-01-01

    Full Text Available Cancer of unknown primary (CUP is the finding of a metastatic cancerous lesion without an established primary source localized within the body. CUP can be of any cancer cell type, however, adenocarcinoma is most often identified by histology. Up to 5% of all malignant diagnoses are classified as CUP. PET is an imaging modality often utilized to distinguish a primary source in the setting of CUP, yet often a primary is never identified. CUP can be further stratified using specific qualifiers as favorable and unfavorable, indicating the potential therapeutic response to treatment regimens. Treatment approach to CUP relies heavily on the cell type identified by histology, the location of the lesion, and the amount of spread within the body. In the typical setting and presentation, per current literature, CUP arises in the 7th decade of life in patients with multiple comorbidities, and often has a poor prognostic value. This case report identifies an atypical presentation of CUP, a 38-year-old Caucasian female with an axillary mobile mass, and no associated systemic symptoms. Biopsy of the node and immunohistochemical staining showed histology consistent with metastatic carcinoma. Mammography, MRI, and PET scan found no evidence of tumor primary or distant metastasis. Further staining confirmed metastatic carcinoma consistent with breast origin, without an established breast primary. As in this case, CUP may present in an atypical manner, warranting a thorough investigation aiming to identify the tumor primary to aid in identification of a proper treatment regimen and approach.

    Olaf Czarnecki

    Full Text Available Strigolactones are a new class of plant hormones that play a key role in regulating shoot branching. Studies of branching mutants in Arabidopsis, pea, rice and petunia have identified several key genes involved in strigolactone biosynthesis or signaling pathway. In the model plant Arabidopsis, MORE AXILLARY GROWTH1 (MAX1, MAX2, MAX3 and MAX4 are four founding members of strigolactone pathway genes. However, little is known about the strigolactone pathway genes in the woody perennial plants.Here we report the identification of MAX homologues in the woody model plant Populus trichocarpa. We identified the sequence homologues for each MAX protein in P. trichocarpa. Gene expression analysis revealed that Populus MAX paralogous genes are differentially expressed across various tissues and organs. Furthermore, we showed that Populus MAX genes could complement or partially complement the shoot branching phenotypes of the corresponding Arabidopsis max mutants.This study provides genetic evidence that strigolactone pathway genes are likely conserved in the woody perennial plants and lays a foundation for further characterization of strigolactone pathway and its functions in the woody perennial plants.

    We wanted to investigate the accuracy of axillary ultrasonography for detecting axillary nodal metastasis in patients with T1-2 breast cancer and we also wanted to determine the factors affecting the sensitivity. Two radiologists performed axillary ultrasonography in 119 consecutive patients with T1-2 breast cancer and clinically uninvolved axillae. We analyzed the accuracy of ultrasonography for detecting axillary nodal metastasis with the histologic results being used as a reference standard. We evaluated the number of involved lymph nodes, T staging and the histologic grade of the tumors. Axillary nodes were involved in 39% of total patients (46/119): 30% of the patients with T1 cancer and 55% of the patients with T2 cancer. The sensitivity, specificity, positive predictive value and negative predictive value were for 52%, 92%, 80% and 75%, respectively. The sensitivity was significantly lower for the cases with one to two lymph nodes metastasis and T1 cancer than in those cases with 3 or more lymph nodes metastasis and T2 cancer (35% and 75% in the cases with 1-2 cancer and the cases with > 3 lymph nodes metastasis, respectively, p = 0.009: 38% and 68% in the cases with T1 and the cases with T2 cancer, respectively, p = 0.045). The ultrasonographic sensitivity for detecting axillary lymph node metastasis is low, especially in the cases with one to two lymph nodes metastasis and the cases with T1 cancer. Detailed analysis and adoption of cytologic examination of the axillary lymph nodes are necessary to improue the accuracy of ultrasonography

    Extracapsular spread (ECS) is frequent, but the specific sites of relapse are seldom given in the literature. In this study it was evaluated, if ECS might be an indicator for axillary irradiation. After a retrospective review of pathology reports, the information about ECS was available in 254 lymph node-positive patients: ECS was absent in 34% (ECS-negative; n=87) and present in 66% (ECS-positive; n=167). All patients were irradiated locally, 78 patients got periclavicular and 74 axillary irradiation (median total dose: 50.4 Gy). 240/254 patients (94.5%) received systemic treatment/s. Mean follow-up was 46 months. The regional relapse rate was 4.6% without ECS versus 9.6% with ECS. The 5-year axillary relapse-free survival was 100% in ECS-negative and 90% in ECS-positive patients (p=0.01), whereas corresponding values for periclavicular relapse-free survival (with ECS: 91%{+-}4%; without ECS: 94%{+-}3%; p=0.77) and local relapse-free survival (with ECS: 86%{+-}4%; without ECS: 91%{+-}3%; p=0.69) were not significantly different. {chi}{sup 2}-tests revealed a high correlation of ECS with T-stage, number of positive lymph nodes and progesterone receptor status, comparisons with estrogen receptor, grade, or age were not significant. In multivariate analysis number of positive lymph nodes was solely significant for regional failure. Dividing the patients into those with one to three and those with four or more positive lymph nodes, ECS lost its significance for axillary failure. ECS was accompanied by an enhanced axillary failure rate in univariate analysis, which was no longer true after adjusting for the number of positive lymph nodes. (orig.)

    Full Text Available Abstract Introduction Lymphadenopathy is a common finding in toxoplasmosis. A breast mass due to toxoplasmosis is very rare, and only a few cases have been reported. We present a case of toxoplasmosis that presented as a swelling in the axillary tail of the breast with a palpable axillary lymph node which mimicked breast cancer. Case presentation A 45-year-old otherwise healthy Caucasian woman presented with a lump on the lateral aspect of her left breast. Her mother had breast cancer that was diagnosed at the age of 66 years. During an examination, we discovered that our patient had a discrete, firm lump in the axillary tail of her left breast and an enlarged, palpable lymph node in her left axilla. Her right breast and axilla were normal. The clinical diagnosis was malignancy in the left breast. Ultrasound and mammographic examinations of her breast suggested a pathological process but were not conclusive. She had targeted fine-needle aspiration cytology (FNAC and core biopsy of the lesions. FNAC was indeterminate (C3 but suggested a possibility of toxoplasmosis. The core biopsy was not suggestive of malignancy but showed granulomatous inflammation. She had a wide local excision of the breast lump and an axillary lymph node biopsy. Histopathology and immunohistochemical studies excluded carcinoma or lymphoma but suggested the possibility of intramammary and axillary toxoplasmic lymphadenopathy. The results of Toxoplasma gondii IgM and IgG serology tests were positive, supporting a diagnosis of toxoplasmosis. Conclusions Toxoplasmosis rarely presents as a pseudotumor of the breast. FNAC and histology are valuable tools for a diagnosis of toxoplasmosis, and serology is an important adjunct for confirmation.

    Full Text Available Objective: To assess the contribution of kinetic characteristics in the discrimination of malignant-benign axillary lymph nodes. Material and Methods: One hundred fifty-five female patients were included in the study. Following magnetic resonance imaging (MRI examinations post-processing applications were applied, dynamic curves were obtained from subtracted images. Types of dynamic curves were correlated with histopathological results in malignant cases or final clinical results in patients with no evidence of malignancy. Sensitivity, specificity, positive likehood ratio (+LHR, negative (-LHR of dynamic curves characterizing the axillary lymph nodes were calculated.Results: A total of 178 lymph nodes greater than 8 mm were evaluated in 113 patients. Forty-six lymph nodes in 24 cases had malignant axillary involvement. 132 lymph nodes in 89 patients with benign diagnosis were included in the study. The sensitivity of type 3 curve as an indicator of malignancy was calculated as 89%. However the specificity, +LHR, -LHR were calculated as 14%, 1.04, 0.76 respectively. Conclusion: Since kinetic analysis of both benign and malignant axillary lymph nodes, rapid enhancement and washout (type 3 they cannot be used as a discriminator, unlike breast lesions. MRI, depending on the kinetic features of the axillary lymph nodes, is not high enough to be used in the clinical management of breast cancer patients.

  19. Potential bud bank responses to apical meristem damage and environmental variables: matching or complementing axillary meristems?

    Full Text Available Soil nutrients, dormant axillary meristem availability, and competition can influence plant tolerance to damage. However, the role of potential bud banks (adventitious meristems initiated only after injury is not known. Examining Central European field populations of 22 species of short-lived monocarpic herbs exposed to various sources of damage, we hypothesized that: (1 with increasing injury severity, the number of axillary branches would decrease, due to axillary meristem limitation, whereas the number of adventitious shoots (typically induced by severe injury would increase; (2 favorable environmental conditions would allow intact plants to branch more, resulting in stronger axillary meristem limitation than in unfavorable conditions; and (3 consequently, adventitious sprouting would be better enabled in favorable than unfavorable conditions. We found strong support for the first hypothesis, only limited support for the second, and none for the third. Our results imply that whereas soil nutrients and competition marginally influence plant tolerance to damage, potential bud banks enable plants to overcome meristem limitation from severe damage, and therefore better tolerate it. All the significant effects were found in intraspecific comparisons, whereas interspecific differences were not found. Monocarpic plants with potential bud banks therefore represent a distinct strategy occupying a narrow environmental niche. The disturbance regime typical for this niche remains to be examined, as do the costs associated with the banks of adventitious and axillary reserve meristems.

    The purpose of this study was to evaluate the occurrence of lymphatic drainage to non-axillary sentinel nodes and to determine the implications of this phenomenon. A total of 549 breast cancer patients underwent lymphoscintigraphy after intratumoural injection of 99mTc-nanocolloid. The sentinel node was intraoperatively identified with the aid of intratumoural administered patent blue dye and a gamma-ray detection probe. Histopathological examination of sentinel nodes included step-sectioning at six levels and immunohistochemical staining. A sentinel node outside level I or II of the axilla was found in 149 patients (27%): internal mammary sentinel nodes in 86 patients, other non-axillary sentinel nodes in 44 and both internal mammary and other non-axillary sentinel nodes in nineteen patients. The intra-operative identification rate was 80%. Internal mammary metastases were found in seventeen patients and metastases in other non-axillary sentinel nodes in ten patients. Staging improved in 13% of patients with non-axillary sentinel lymph nodes and their treatment strategy was changed in 17%. A small proportion of clinically node negative breast cancer patients can be staged more precisely by biopsy of sentinel nodes outside level I and II of the axilla, resulting in additional decision criteria for postoperative regional or systemic therapy.

    The aim of this study was to compare axillary and tympanic membrane (TM) temperature measurements to rectal temperature in a large group of clinical canine patients. We also sought to ascertain whether certain factors affected the differences between the measurements and to compare the ease of measurement. Axillary temperatures were easy to obtain but tended to be lower than rectal readings (median difference 0.6°C). In 54.7 per cent of dogs there was a difference of >0.5°C between the two readings. Weight, coat length, body condition score and breed size were significantly associated with the difference between the rectal and axillary temperature. TM temperatures were more similar to rectal temperatures (median difference 0°C) but in 25 per cent of dogs, there was a difference of >0.5°C between rectal and TM readings. TM measurements were less well tolerated than axillary measurements. None of the factors assessed were associated with the difference between the rectal and TM temperature. As a difference of >0.5°C has previously been described as unacceptable for different methods of temperature measurement, neither axillary nor TM temperatures are interchangeable with rectal temperatures for the measurement of body temperature.

    The purpose of this study was to evaluate the fistulographic features of malfunctioning axillary loop-configured arteriovenous grafts and the efficacy of percutaneous interventions in failed axillary loop-configured arteriovenous grafts. Ten patients with axillary loop-configured arteriovenous grafts were referred for evaluation of graft patency or upper arm swelling. Fistulography and percutaneous intervention, including thrombolysis, percutaneous transluminal angioplasty and stent placement, were performed. Statistical analysis of the procedure success rate and the primary and secondary patency rates was done. Four patients had graft related and subclavian venous stenosis, two patients had graft related stenosis and another four patients had subclavian venous stenosis only. Sixteen sessions of interventional procedures were performed in eight patients (average: 2 sessions / patient) until the end of follow-up. An interventional procedure was not done in two patients with central venous stenosis. The overall procedure success rate was 69% (11 of 16 sessions). The post-intervention primary and secondary patency rates were 50% and 63% at three months, 38% and 63% at six months and 25% and 63% at one year, respectively. Dysfunctional axillary loop-configured arteriovenous grafts almost always had subclavian venous and graft-related stenosis. Interventional treatments are helpful to overcome this and these treatments are expected to play a major role in restoring and maintaining the axillary loop-configured arteriovenous loop grafts

    Full Text Available Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet syndrome. However, we emphasize that new instruments should be designed and further studies are needed to evaluate in vivo results.

    Shoot branching is one of the major determinants of plant architecture. Polar auxin transport in stems is necessary for the control of bud outgrowth by a dominant apex. Here, we show that following decapitation in pea (Pisum sativum L.), the axillary buds establish directional auxin export by subcellular polarization of PIN auxin transporters. Apical auxin application on the decapitated stem prevents this PIN polarization and canalization of laterally applied auxin. These results support a model in which the apical and lateral auxin sources compete for primary channels of auxin transport in the stem to control the outgrowth of axillary buds. PMID:21219506

    Sentinel lymph node detection (SLND) with radiocolloid has become widely used for evaluation of nodal metastasis in primary breast cancer. However, the procedure for recurrent breast cancer is not well established. Contralateral axillary node metastasis is uncommon. We report 2 cases of contralateral axillary node metastasis with recurrent breast cancer. In the first case, contralateral node metastasis was found by SLND. In the other case without SLND, contralateral node metastasis developed after resection of local recurrence. FDG-avid contralateral node was pathologically diagnosed as metastasis. The SLND might be useful in patients with local recurrence after conservative breast cancer surgery. PMID:24368539

    Full Text Available Median nerve is commonly formed by the union of the lateral and medial cord of the brachial plexus, which embrace the third part of the axillary artery. Formation of a median nerve's loop is a very rare condition. We present a cadaveric case, in which the right median nerve was found at the upper arm forming a fusiform neural loop penetrated by a superficial brachial artery, which continued over the forearm as the radial artery. The literature concerning nerve loops and traversing arteries is discussed, as well as the relevant embryology. We consider that such nerve loops constitute vulnerable sites of the nerve trunk since it is compressed by the pulsation of the abnormal traversing artery. Moreover, neurosurgeons should keep in mind that in case of existing arterial variation, variation of the associated neural structures may co-exist. [Int J Res Med Sci 2015; 3(8.000: 2123-2125

    Preoperative diagnosis of axillary metastases in breast cancer patients enables treatment planning. We aimed to evaluate the diagnostic accuracy of axillary ultrasonography and percutaneous biopsy, both alone and in combination, in detecting axillary metastases in patients with breast cancer and to assess the impact of these techniques on the patients' management. Materials and methods: Retrospective study of consecutive patients with suspected breast cancer examined between October 2006 and December 2008. The diagnosis of a primary tumor was histologically confirmed in all patients. All patients underwent axillary ultrasonography and percutaneous core biopsy (14G) of suspicious lymph nodes. We evaluated the morphological characteristics of the lymph nodes by ultrasonography. We calculated the diagnostic accuracy of ultrasonography and of core biopsy, and assessed the impact of these techniques on patients' treatment. Results: We evaluated 675 axillary regions and performed 291 core biopsies of axillary lymph nodes in 662 patients. In 650 patients, breast cancer was histologically confirmed and in 12 patients malignant tumors in other locations were confirmed. The sensitivity and specificity of axillary ultrasonography were 63.2% and 88.7%, respectively. The absence of a fatty hilum within the lymph node was the ultrasonographic finding with the highest positive predictive value for malignancy (93.1%). The sensitivity and specificity of axillary core biopsy were 69.1% and 100%, respectively. Sentinel lymph node biopsy was avoided in 33% of initial candidates and immediate breast reconstruction was undertaken in 35.1% of the patients with mastectomy and negative axillary core biopsy. Conclusions: Ultrasonography and axillary core biopsy enable adequate pretreatment staging in patients with breast cancer and has a positive impact on their management.

    Background and purpose: to evaluate the impact of extracapsular extension (ECE) on locoregional and distant control in breast cancer patients with one to three positive axillary lymph nodes treated with postoperative irradiation. As shown in literature, ECE is diagnosed in up to 30% of node-positive breast cancer patients. Consequences of ECE and prognosis of these patients are unclear. Patients and methods: the medical records of 1,142 node-positive females with a carcinoma of the breast, postoperatively irradiated between 1994 and 2003, were retrospectively reviewed. Of the 274 patients presenting with one to three positive axillary lymph nodes, 91 (33.2%) showed ECE, While all patients were irradiated using tangential fields, only eight out of 274 patients received additional nodal irradiation. Results: patients' mean age was 58.2 years (range, 28-96 years), and the mean observation period 42.9 months (range, 6.6-101 months). In 93.4% of patients, locoregional control was achieved. On multivariate analysis of metastases-free survival, the hazard ratios for ECE and histological grade 3 were 2.71 (95% confidence interval [CI], 1.316-5.581; p = 0.007) and 2.435 (95% CI, 1.008-5.885; p = 0.048), respectively. The 3-year and 5-year metastases-free survival rates for patients with ECE were 78% and 66%, compared to 90% and 87% in patients without ECE (p = 0.0048). Conclusion: locoregional recurrence remains low in breast cancer patients (one to three positive axillary lymph nodes {+-} ECE) treated with surgery, adequate axillary dissection, and tangential field irradiation only. However, ECE is significantly linked to a considerable risk for subsequent distant failure. (orig.)

    A retrospective evaluation of embolotherapy in patients with arterial liver hemorrhages was carried out. Twenty-six patients, ranging in age from 10 days to 77 years with active arterial liver hemorrhages, underwent non-surgical embolotherapy. Bleeding was attributed to trauma (n = 21), tumor (n = 3), pancreatitis (n = 1), or unknown cause (n = 1). Twenty-nine embolizations were performed via a transfemoral (n = 26) or biliary (n = 2) approach. One bare Wallstent was placed into the common hepatic artery via to an axillary route to cover a false aneurysm due to pancreatitis. Treatment was controlled in 4 patients by cholangioscopy (n = 2) or by intravascular ultrasound (n = 2). Prior surgery had failed in 3 patients. Intervention controlled the hemorrhage in 24 of 26 (92 %) patients within 24 h. Embolotherapy failed in 1 patient with pancreatic carcinoma and occlusion of the portal vein. In 1 patient with an aneurysm of the hepatic artery treated by Wallstent insertion, total occlusion was not achieved in the following days, as demonstrated by CT and angiography. However, colour Doppler flow examination showed no flow in the aneurysm 6 months later. Complications were one liver abscess, treated successfully by percutaneous drainage for 10 days, and one gallbladder necrosis after superselective embolization of the cystic artery. Embolization is a effective tool with a low complication rate in the treatment of liver artery hemorrhage, even in patients in whom surgery has failed. (orig.) (orig.) With 2 figs., 26 refs.

    SlARF2a is expressed in most plant organs, including roots, leaves, flowers and fruits. A detailed expression study revealed that SlARF2a is mainly expressed in the leaf nodes and cross-sections of the nodes indicated that SlARF2a expression is restricted to vascular organs. Decapitation or the application of 6-benzylaminopurine (BAP) can initially promote axillary shoots, during which SlARF2a expression is significantly reduced. Down-regulation of SlARF2a expression results in an increased frequency of dicotyledons and significantly increased lateral organ development. Stem anatomy studies have revealed significantly altered cambia and phloem in tomato plants expressing down-regulated levels of ARF2a, which is associated with obvious alterations in auxin distribution. Further analysis has revealed that altered auxin transport may occur via altered pin expression. To identify the interactions of AUX/IAA and TPL with ARF2a, four axillary shoot development repressors that are down-regulated during axillary shoot development, IAA3, IAA9, SlTPL1 and SlTPL6, were tested for their direct interactions with ARF2a. Although none of these repressors are directly involved in ARF2a activity, similar expression patterns of IAA3, IAA9 and ARF2a implied they might work tightly in axillary shoot formation and other developmental processes.

    Changes in acidity of Udic Ferrosols, caused by growth of Choerospondias axillaris (Roxb.) Burtt et Hill, in comparison to wild grass, were investigated for pH distribution in the soil profile, exchangeable acidity, and cation status in the soil leachate of a simulated leaching experiment. Soils were sampled in profiles at 5 cm intervals to a depth of 100 cm. In the15-60 cm layer the soils with 10-year old C. axillaris had significantly lower pH (P < 0.05), with the largest difference being 0.41; and in the 25-75 cm soil depths, especially in the 30-55 cm layer, the soils had a significantly higher exchangeable acidity, ranging 1.93 to 3.02 cmolc kg-1. There was also higher aluminum, potassium, and sodium contents in the soil leachate under C. axillaris than with wild grasses. This suggested that the growth of C. axillaris accelerated acidification of Udic Ferrosols and promoted soil clay mineral weathering.

    Breast cancer is the most frequent cancer of women in western countries. There are one million new cases per year in the world which represents 22% of all female cancers, and more than 370.000 deaths due to breast cancer per year (14% of cancer mortality). More than half of breast cancers are associated with axillary nodal involvement. Post-operative radiation therapy (XRT) is a crucial part of locoregional treatment in axillary nodal involvement breast cancer owing to a 15-years risk reduction of locoregional recurrence of 70% and to a 5.4% risk reduction of specific mortality. In 3D-conformal irradiation in such breast cancers, target volumes are chest wall when mastectomy was performed or breast and boost of tumor bed in case of breast conservative surgery, and supra-clavicular and/or axillary and/or internal mammary node areas. The main organs at risk are ipsilateral lung, heart and brachial plexus. The aim of this article is to describe epidemiologic, radio anatomic and prognostic features of axillary nodal involvement breast cancer and to propose guidelines for 3D-conformal treatment planning in locally advanced breast cancers. This review is illustrated by a case report. (authors)

    Competency in anesthesia traditionally has been determined subjectively in practice. Optimal training in procedural skills requires valid and reliable forms of assessment. The objective was to examine a procedure-specific clinical assessment tool for ultrasound-guided axillary brachial plexus block for inter-rater reliability and construct validity in a clinical setting.

  2. Multi-detector row CT in the assessment of axillary lymph node metastasis in breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study is to evaluate the diagnostic capability instead of clinical efficacy of multi-detector row CT (MDCT) in the assessment of axillary lymph node metastasis in breast cancer. MDCT was performed in 63 patients with breast cancer, and multiplanar reformation (MPR) and volume rendering (VR) images were reconstructed for the evaluation of bilateral axillary lymph nodes. Two hundred sixty eight lymph nodes were depicted with MDCT, and correlation with pathological findings was performed. The short axis length of lymph node was measured on MPR image, and the shape of the nodes was analyzed with the pathological results statistically. The diagnostic criteria on size and shape of lymph node metastasis were discussed Dynamic study with contrast media was also performed, and the CT value ratios (CTVR) of the lymph nodes and breast tumors were calculated. No relevance of axillary lymph node metastasis was noted to the pathological types of breast cancer. The average short axis length of the ipsilateral axillary nodes was 8.9 mm±3.8 (SD) while that of the contralateral nodes was 4.9 mm±1.1 (SD) showing significant difference. More than 6.5 mm in short length of the lymph node was thought to be an effective criterion for positive metastasis, and its sensitivity was 96%. Soybean-shape lymph node was statistically common in metastasis, while non-metastatic nodes were commonly demonstrated as letter ''c'' shape or ring-like shape. Statistical relevance was obtained between the CTVR of axillary lymph nodes and that of breast tumors, suggesting clinical usefulness of dynamic study using contrast media in the evaluation of lymph node metastasis. With MPR and VR images using MDCT, more accurate morphological evaluation of axillary lymph nodes was possible. When soybean-shape node with more than 6.5 mm in short axis is depicted in the axillar region on MDCT metastasis should be the consideration.

    Full Text Available Axillary arch is an additional muscle bundle of various dimensions extending usually from the latissimus dorsi in the posterior fold of the axilla, to the pectoralis major or other neighboring muscles and bones. In the present case presence of such unusual axillary arch innervated by the median nerve has been reported. During routine dissection of axilla region in one of the upper limbs, the occurrence of axillary arch was observed. The muscle fibers were arising from the belly of latissimus dorsi and were getting inserted to the tendon of coracobrachilais and lateral lip of bicipital groove. As it passed through the axilla it divided into 2 slips, enclosing the axillary vessels and nerves related to them. The fleshy fibers of the axillary arch were innervated by 2 small twigs from the median nerve. Though the occurrence of the axillary arch is very common, axillary arch with 2 slips getting innervated by the median nerve is not been reported so far. Further, a detailed literature review was done and the surgical and clinical importance of the case was discussed.

    The presence of axillary lymph node metastases is the most important prognostic factor in breast cancer and can influence the selection of adjuvant therapy, both chemotherapy and radiotherapy. In this work we present a set of kinetic statistics derived from DCE-MRI for predicting axillary node status. Breast DCE-MRI images from 69 women with known nodal status were analyzed retrospectively under HIPAA and IRB approval. Axillary lymph nodes were positive in 12 patients while 57 patients had no axillary lymph node involvement. Kinetic curves for each pixel were computed and a pixel-wise map of time-to-peak (TTP) was obtained. Pixels were first partitioned according to the similarity of their kinetic behavior, based on TTP values. For every kinetic curve, the following pixel-wise features were computed: peak enhancement (PE), wash-in-slope (WIS), wash-out-slope (WOS). Partition-wise statistics for every feature map were calculated, resulting in a total of 21 kinetic statistic features. ANOVA analysis was done to select features that differ significantly between node positive and node negative women. Using the computed kinetic statistic features a leave-one-out SVM classifier was learned that performs with AUC=0.77 under the ROC curve, outperforming the conventional kinetic measures, including maximum peak enhancement (MPE) and signal enhancement ratio (SER), (AUCs of 0.61 and 0.57 respectively). These findings suggest that our DCE-MRI kinetic statistic features can be used to improve the prediction of axillary node status in breast cancer patients. Such features could ultimately be used as imaging biomarkers to guide personalized treatment choices for women diagnosed with breast cancer.

    BACKGROUND: Axillary nodal status is an important prognostic predictor in patients with breast cancer. This study evaluated the sensitivity and specificity of ultrasound-guided core biopsy (Ax US-CB) at detecting axillary nodal metastases in patients with primary breast cancer, thereby determining how often sentinel lymph node biopsy could be avoided in node positive patients. STUDY DESIGN: Records of patients presenting to a breast unit between January 2007 and June 2010 were reviewed retrospectively. Patients who underwent axillary ultrasonography with or without preoperative core biopsy were identified. Sensitivity, specificity, positive predictive value, and negative predictive value for ultrasonography and percutaneous biopsy were evaluated. RESULTS: Records of 718 patients were reviewed, with 445 fulfilling inclusion criteria. Forty-seven percent (n = 210\\/445) had nodal metastases, with 110 detected by Ax US-CB (sensitivity 52.4%, specificity 100%, positive predictive value 100%, negative predictive value 70.1%). Axillary ultrasonography without biopsy had sensitivity and specificity of 54.3% and 97%, respectively. Lymphovascular invasion was an independent predictor of nodal metastases (sensitivity 60.8%, specificity 80%). Ultrasound-guided core biopsy detected more than half of all nodal metastases, sparing more than one-quarter of all breast cancer patients an unnecessary sentinel lymph node biopsy. CONCLUSIONS: Axillary ultrasonography, when combined with core biopsy, is a valuable component of the management of patients with primary breast cancer. Its ability to definitively identify nodal metastases before surgical intervention can greatly facilitate a patient\\'s preoperative integrated treatment plan. In this regard, we believe our study adds considerably to the increasing data, which indicate the benefit of Ax US-CB in the preoperative detection of nodal metastases.

  6. Axillary lymph nodes siliconoma in a woman with intracapsular implant rupture

    International Nuclear Information System (INIS)

    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

    Full Text Available Background Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, andin some instances, staining of clothes that may socially and psychologically impair affectedindividuals. Various types of surgical procedures have been developed for the treatment ofaxillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneouspulsed neodymium: yttrium-aluminum-garnet (Nd-YAG laser treatment for the treatment ofaxillary osmidrosis.Methods Twenty-nine patients with axillary osmidrosis were included in this study. Patientswere categorized according to the results of an axillary malodor grading system, and asubcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for theappropriate distribution of laser energy was determined using the iodine starch test (Minor’stest against a grid pattern composed of 2×2 cm squares. The endpoint of exposure was300 to 500 J for each grid, depending on the preoperative evaluation results. The resultswere evaluated by measurement of axillary malodor both pre- and postoperatively using thegrading system and iodine starch test.Results The average follow-up period was 12.8 months. Nineteen patients had a fair-togoodresult and ten patients had poor results. The postoperative Minor’s test demonstratedthat there were remarkable improvements for patients with mild to moderate symptoms.Complications including superficial second degree burns (n=3 were treated in a conservativemanner. A deep second degree burn (n=1 was treated by a surgical procedure.Conclusions Subcutaneous pulsed Nd-YAG laser has many advantages and is an effectivenoninvasive treatment for mild to moderate axillary osmidrosis.

    Today evaluation of axillary involvement can be routinely performed with the technique of sentinel lymph node biopsy (SLNB). One of the greatest advantages of SLNB is the nearly total absence of local postoperative complications. It is important to understand whether SLNB is better than axillary lymph-node dissection (ALND) for staging axillary nodal involvement. The aim of the study was to evaluate the axillary staging accuracy comparing three different methods: axillary dissection, sentinel node biopsy with the traditional 4-6 sections and sentinel node biopsy with complete analysis of the lymph node. 527 consecutive patients (525 females and 2 males) with invasive breast cancer < or = 3 cm and clinically negative axillary nodes were divided into 3 different groups: group A treated with axillary dissection, group B treated with sentinel nodal biopsy analysed with 4-6 sections, and group C treated with sentinel node biopsy with analysis of the entire node. All patients underwent a quadrantectomy to treat the tumor. Group differences and statistical significance were assessed by ANOVA. The percentages of N+ in group A and group B were 25.80% and 28% respectively, while in the third group it rose to 45%, or almost half the patients. The differences among the three groups were statistically significant (p = 0.02). From our analysis of the data it emerges that axillary dissection and sentinel node biopsy with analysis of 4-6 sections have the same accuracy in staging the nodal status of the axilla; analysis of the entire sentinel lymph node revealed an increased number of patients with axillary nodal involvement, proving more powerful in predicting nodal stage. SLNB with complete examination of the SLN removed can be considered the best method for axillary staging in breast cancer patients with clinical negative nodes. In our study, the percentage of metastases encountered after complete examination of SLN was 45% compared to the accuracy of axillary dissection that

    Purpose: To evaluate the effectiveness and safety of covered stents for the management of iatrogenic arterial injury. Materials and Methods: Between 03/1998 and 12/2009, 31 patients underwent selective covered stent implantation after iatrogenic arterial injury. 12/31 of these patients (38.7 %) were hemodynamically unstable. Six different endovascular covered stent types were utilized. The primary endpoints of this study were technical and clinical success and rates of minor and major complications. Results: Initial angiograms demonstrated active extravasation in 19 (61.3 %) patients and pseudoaneurysms in 12 (38.7 %) patients. The following sites of bleeding origin were detected: axillary artery, subclavian artery, common iliac artery, external iliac artery, internal iliac artery, common femoral artery, superficial femoral artery, popliteal and fibular artery, femoro-popliteal and popliteo-crural bypasses, common hepatic artery, aberrant hepatic artery, cystic and gastroduodenal artery. In all patients bleeding was effectively controlled by covered stent implantation resulting in an immediate technical success of 100 %. Clinical success attributed to covered stent implantation was documented in 30 of the 31 patients (96.8 %). Major complications included death in four patients (11.1 %), acute thrombosis with arm ischemia in one patient (2.8 %) and stent fracture with associated pseudoaneurysm in another patient (2.8 %). In 2/31 patients (6.5 %) covered stent failure was detected and successfully treated by implantation of a second covered stent. Conclusion: Emergency and elective implantation of covered stents may be used for minimally invasive and effective management of iatrogenic arterial injury. (orig.)

    Background: The presence of axillary lymph node metastasis is the most important prognostic factor and an essential part of staging and prognosis of breast cancer. Purpose: To elucidate the usefulness and accuracy of ultrasonography (United States), fluorodeoxyglucose positron emission tomography (FDG-PET) scan, and combined analysis for axillary lymph node staging in breast cancer. Material and Methods: A total of 250 consecutive breast cancer patients who had undergone US, FDG-PET, and sentinel lymph node biopsy (SLNB) before surgery from January 2005 to December 2006 were included in the study. If an axillary lymph node had a length to width ratio =1.5 or cortical thickening =3 mm or compression of the hilum on US, focal hot uptake (maximal standardized uptake value, SU V{sub max} =2.0) in the ipsilateral axilla on FDG-PET, it was considered to be a metastatic lymph node. In combined analysis of US and FDG-PET, the interpretation was considered positive if at least two of any of the criteria were met. Each imaging finding was compared with a pathologic report regarding the presence of axillary lymph node metastasis, the number of metastatic lymph nodes, and the T stage of the breast mass. Results: Pathologically confirmed axillary lymph node metastasis was noted in 73 cases (29.2%). The mean number of metastatic lymph nodes in pathology was 3.1 +- 3.2, and the size of breast cancer was 2.0 +- 1.04 cm. In the detection of lymph node metastasis, the diagnostic accuracy of US was 78.8% and that of FDG-PET was 76.4%. On combined US and FDG-PET, accuracy was improved (91.6%). The number of metastatic lymph nodes on pathology was correlated with the positivity of US and FDG-PET (P < 0.01). Conclusion: Combined evaluation of US and FDG-PET was a sensitive and accurate method for axillary lymph node staging in breast cancer

    Full Text Available Trough computed tomography (CT, it is possible to evaluate lymph nodes in detail and to detect changes in these structures earlier than with radiographs and ultrasound. Lack of information in the veterinary literature directed the focus of this report to normal aspects of the axillary and mediastinal lymph nodes of adult dogs on CT imaging. A CT scan of 15 normal adult male and female Rottweilers was done. To define them as clinically sound, anamnesis, physical examination, complete blood count, renal and hepatic biochemistry, ECG, and thoracic radiographs were performed. After the intravenous injection of hydrosoluble ionic iodine contrast medium contiguous 10mm in thickness thoracic transverse images were obtained with an axial scanner. In the obtained images mediastinal and axillary lymph nodes were sought and when found measured in their smallest diameter and their attenuation was compared to musculature. Mean and standard deviation of: age, weight, body length and the smallest diameter of the axillary and mediastinal lymph nodes were determined. Mean and standard deviation of parameters: age 3.87±2.03 years, weight 41.13±5.12, and body length 89.61±2.63cm. Axillary lymph nodes were seen in 60% of the animals, mean of the smallest diameter was 3.58mm with a standard deviation of 2.02 and a minimum value of 1mm and a maximum value of 7mm. From 13 observed lymph nodes 61.53% were hypopodense when compared with musculature, and 30.77% were isodense. Mediastinal lymph nodes were identified in 73.33% of the dogs; mean measure of the smallest diameter was 4.71mm with a standard deviation of 2.61mm and a minimum value of 1mm, and a maximum value of 8mm. From 14 observed lymph nodes 85.71% were isodense when compared with musculature and 14.28% were hypodense. The results show that it is possible to visualize axillary and mediastinal lymph nodes in adult clinically sound Rottweilers with CT using a slice thickness and interval of 10mm. The

    Hayes, Brian D

    2012-02-01

    INTRODUCTION: Fine needle aspiration cytology (FNAC) of radiologically abnormal axillary lymph nodes in patients with breast cancer can identify patients suitable for primary axillary clearance (AC) rather than sentinel node biopsy, enabling surgical axillary staging by a single operation. This study assessed the accuracy of FNAC in predicting positive axillary lymph nodes. METHODS: 161 patients with screen-detected invasive carcinoma and who had pre-operative FNAC of a radiologically abnormal axillary lymph node were identified from two screening units, The axillary FNAC reports were correlated with sentinel node biopsy and AC reports, and sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated. RESULTS: FNAC had a moderate sensitivity (66.3%) and NPV (71.8%), and a high specificity (98.7%) and PPV (98.3%). Most patients (86%) had a single axillary operation. The sensitivity was highest in grade 3 (81.8%) and ductal type (77.8%) tumours. The sensitivity was lower in tumours of special type (34.8%), grade 1 tumours (50%) and those without lymphovascular invasion (LVI) (55.9%). The NPV was highest in pT1 (86.7%) and in grade 1 (84.5%) tumours, and lowest (44%) in tumours with LVI. The PPV was 100% in grade 1 and 3 tumours, stage pT2 and pT3 tumours and those without LVI, and was high (>96%) in all other groups. In lymph-node-positive patients, the mean number of lymph nodes involved was higher in the case of a positive (6.4) than negative FNAC (4.4). CONCLUSIONS: FNAC of ultrasonically abnormal axillary lymph nodes achieved surgical staging by a single operation in most patients with screen-detected invasive breast carcinoma, with moderate sensitivity and high specificity.

    The aim of this study was to evaluate the association between pretreatment molecular and clinical factors and axillary lymph node metastases in early breast cancer. A total of 367 consecutive breast cancer patients with cT1-2NxM0 who underwent breast conserving surgery and axillary lymph node dissection followed by whole breast irradiation were enrolled. We evaluated the pathologic tumor and node status, tumor differentiation, calcification, and lymphovascular invasion, the status of estrogen receptor (ER), progesterone receptor (PR), epidermal growth factor receptor 1 (EGFR1), and human epidermal growth factor receptor 2 (HER2), the expression of E-cadherin, P53, and Ki-67 index. Totally, 108 (29.4%) of the 367 patients had positive axillary lymph nodes. An increased tumor size (P = 0.024), the presence of lymphovascular invasion (P 20% (P = 0.038) were significantly associated with axillary lymph node metastases on the multivariate analysis. In our study, 86.2% of the patients with all the unfavorable factors had an involvement of axillary nodal metastases, and only 12.2% of the patients with all the favorable predictors had positive axillary nodes. The predictive power was significant on the receiver operating curve (P positive ALNM on multivariate analysis for the patients with cT1-2 breast cancer. Clinicians simply could predict the probability of ALNM after verifying the molecular and clinical factors in early breast cancer. PMID:27196477

    Objective: To evaluate the role of US-guided core biopsy in detection of metastatic axillary lymph nodes in preoperative staging of breast cancer. Materials and methods: US-guided core biopsy of suspicious axillary lymph nodes was performed in 39 patients with breast cancer. Biopsy results were compared to the axillary dissection results. Sensitivity, specificity and accuracy of the core biopsy in the detection of malignancy were calculated. Results: Thirty-nine patients were assessed with biopsy; 30 patients were found to have metastatic carcinoma and nine had benign reactive hyperplasia. In 26 of 30 cases with biopsy-proven metastatic disease, there were malignant lymph nodes detected at axillary dissection. Four cases that had positive biopsy results and negative axillary dissection were accepted as complete response to chemotherapy. In three of nine cases with benign reactive hyperplasia, axillary dissection revealed metastatic disease. No significant complications were observed other than pain responding to analgesics. The sensitivity, specificity and accuracy of core biopsy in detection of malignancy were 90%, 100% and 92%, respectively. The results were statistically significant (p < 0.001). Conclusion: Ultrasonographically detected lymph nodes can be easily assessed by US-guided biopsy. Core biopsy is a reliable and easily performed method without significant complications.

    2012-01-01

    Full Text Available Introduction. Patients with a positive sentinel lymph node biopsy may undergo delayed completion axillary dissection. Where intraoperative analysis is available, immediate completion axillary dissection can be performed. Alternatively, patients may undergo primary axillary dissection for breast cancer, historically or when preoperative assessment suggests axillary metastases. This study aims to determine if there is a difference in the total number of lymph nodes or the number of metastatic nodes harvested between the 3 possible approaches. Methods. Three consecutive comparable groups of 50 consecutive patients who underwent axillary dissection in each of the above contexts were identified from the Portsmouth Breast Unit Database. Patient demographics, clinicopathological variables, and surgical treatment were recorded. The total pathological nodal count and the number of metastatic nodes were compared between the groups. Results. There were no differences in clinico-pathological features between the three groups for all features studied with the exception of breast surgical procedure (P<0.001. There were no differences in total nodal harvest (P=0.822 or in the number of positive nodes harvested (P=0.157 between the three groups. Conclusion. The three approaches to axillary clearance yield equivalent nodal harvests, suggesting oncological equivalence and robustness of surgical technique.

    Breast cancer is the most common malignancy among women, leading to hundreds of thousands of deaths annually around the world. Lymph node status is the most important prognostic indicator in newly diagnosed breast cancer. The presence of axillary lymph node metastases has major prognostic implications in breast cancer patients, and it is an important criterion in determining the need for adjuvant chemotherapy. There is not an accurate anatomical test for detecting axillary lymph node metastasis and clinical examination has inappropriate diagnostic values. Routine lymph node dissection is the only accepted method for therapeutic decisions but it is invasive and produces significant morbidity such as lymphedema and infections. On the other hand, an important proportion of breast cancer patients are nodenegative. Ultrasonography has also been reported to be helpful, especially in conjunction with fine needle aspiration biopsy

    The 8 years (1967-1975) experience with axillary-femoral and femoro-femoral grafts in 40 patients is presented; 6 females and 34 males, between 50 and 90 years of age, with arteriosclerosis, all complicated by chronic illnesses. The results have been satisfactory, as the grafts are functioning from 2 months to 80 months (6 years, 8 months), most of them being more than 12 months old. Twenty eight of the 40 patients operated are alive. Four patients (10%) had infection of their grafts. In 6 (15%) the graft closed because of severe progresive distal obstruction. Three patients (7.5%) died in the first 32 post-operative days. In 9 (22.5%) the deaths were not related to surgery. The indications for placement of axillary-femoral and femoro-femoral grafts is established.

    2011-01-01

    Full Text Available CXCR4 is a 7-transmembrane G-protein chemokine receptor that allows for migration of hematopoietic cells from the bone marrow to the peripheral lymph nodes. Research has shown CXCR4 to be implicated in the invasion and metastasis of several cancers, including carcinoma of the breast. CXCL12 is the ligand for CXCR4 and is highly expressed in areas common for breast cancer metastasis, including the axillary lymph nodes. Axillary lymph nodes positive for breast carcinoma have been an important component of breast cancer diagnosis, treatment, and subsequent research. The goal of this paper is to analyze the literature that has explained the pathways from CXCR4 expression to breast cancer metastasis of the lymph nodes and the prognostic and/or predictive implications of lymph node metastases in the presence of elevated CXCR4.

    2011-01-01

    Full Text Available Primary Fallopian tube malignancy is considered a rare disease and is often mistaken histologically and clinically for ovarian cancer. The etiology is poorly understood, and it typically presents at an advanced disease stage, as symptoms are often absent in the initial period. As a result, primary fallopian tube cancer is generally associated with a poor prognosis. We present the case of a 45-year-old female who presents with a 5-day history of left axillary swelling and a normal breast examination. Mammogram and biopsy of a lesion in the left breast revealed a fibroadenoma but no other abnormalities. Initial sampling of the axillary node was suspicious for a primary breast malignancy, but histology of the excised node refuted this. PET-CT showed an area of high uptake in the right pelvis, and a laparoscopy identified a tumor of the left fallopian tube which was subsequently excised and confirmed as a serous adenocarcinoma.

    Full Text Available Context : Pure mucinous carcinoma of the male breast is an extremely rare neoplasm. It is characterized by a lower incidence of metastatic nodal involvement and a higher survival rate than invasive ductal carcinomas. Case Report : We report the case of a 75-year-old male who presented with a retroareolar mass of the right breast. The patient underwent radical mastectomy including right axillary lymph node dissection. The tumor was well demarcated and had a friable consistency with a gelatinous appearance. Histologically, the diagnostic of pure mucinous carcinoma with lymph node metastasis was performed. After surgery, the patient received chemotherapy, radiotherapy, and hormonotherapy (Tamoxifen. The patient remained free of disease for 36 months after surgery. Conclusion : Pure mucinous carcinoma of the male breast is a very rare tumor; in which axillary nodal disease is exceptional.

    Full Text Available Axillary brachial plexus block is an effective method of anaesthesia for the surgeries performed on the hand, forearm and distal third of the arm. However it has the risk of serious complications such as cardiovascular and central nervous system toxicity. Levobupivacaine is a long acting amide local anaesthetic used for epidural, caudal, spinal, infiltration and peripheral nerve blocks. Levobupivacaine is the S (- isomer of racemic bupivacaine and has a lower risk of cardiovascular, central nervous system toxicity than bupivacaine. However central system toxicity cases due to absorption of the drug into the systemic circulation has been reported. Here, we report a case having no vascular puncture during axillary brachial plexus block performance but developing convulsion due to levobupivacain after the intervention.

    2002-09-01

    Hyperhidrosis is an invalidating condition, and one that is difficult to treat. It is characterized by an excessive and uncontrolled production of sweat by the sweat glands, often causing psychological, social, and occupational problems for the patient. Hyperhidrosis can be distinguished in two forms: idiopathic (of unknown etiology), or secondary, due to an alteration of the endocrine system (ex: hyperthyroidism, neuropathy, neoplasia etc.) It is found in about 0.3-0.5% of the population and can be localized (axillary, palmar, plantar, facial) or diffused. The subcutaneous injection of type A botulinum toxin, until now used only for the treatment of blepharospasm or hemifacial spasm, has shown to be a useful treatment for localized hyperhidrosis. The objective of the authors is to evaluate the therapeutic efficacy, safety, and management of botulinum toxin treatment in patients affected with axillary or palmar hyperhidrosis resistant to conventional therapies.

  12. Technological evolution of axillary lymph nodes: Radiological visualisation in breast cancer patients

    International Nuclear Information System (INIS)

    Full text: In patients with breast cancer, detection of axillary lymph node spread has a great prognostic significance. Visualisation of lymphatic glands is attracting attention of radiologists since long. Lymphogram usually shows 4-9 lymph glands as compared to 8 to 50 identified during surgical intervention. Lymphography is a laborious and complicated process requiring specific skills. Likewise, the evaluation and interpretation of results depends upon the experience of the specialist. We evaluated 234 breast cancer patients and found that lymphograms of these patients initially detected 1-2 central axillary lymph nodes followed by others. During surgical intervention, the total number of lymphatic glands removed from these patients was 3,241 of which only 2,693 (83.1%) were seen on lymphography. On further evaluation it was found that the largest groups of lymphatic nodes were seen in the following pattern (i) central axillary (ii) subclavicular (iii) lateral, with central axillary lymph nodes being the biggest (1.5 - 2 cm) and subclavicular the smallest (0.2 - 0.5 cm). Sternal lymph nodes receive lymph from medial quadrants of the breast and / or if the axillary lymph nodes are obstructed by metastases. The results of lymphography and post-operative examination matched in 71.7-75 % of cases. False positivity was seen in 19.2 % and false negative 9.1 % instances. As this method was not sufficiently selective and specific, its relative upsurge receded backwards and was forgotten. The last decade of the twentieth century saw a sentinel node (SN) concept. In advanced countries, the possibility to detect breast cancer of up to 1 cm diameter corresponding to T1A category, when the axillary lymph nodes still are not involved in malignant growth, accounts about 50%. Hence the search of lymphatic spread vis-a-vis sentinel node detection has gained more importance. Earlier, SN detection involved colour contrast methods, which was reasonably sensitive and specific in

    Breast cancer is the second leading cause of cancer death in women. Currently, mammography and physical breast examination, both non-invasive techniques, provide the two most effective methods available for screening potential breast cancer patients. During the management of patients, however, several invasive techniques such as axillary lymph node dissection, core biopsies and lumpectomies, are utilized to determine the stage or malignancy of the disease with significant cost and morbidity associated with them. Positron Emission Tomography (PET), using [F-18] fluorodeoxyglucose (FDG) tracer is a sensitive and non-invasive imaging modality that may be a cost-effective alternative to certain invasive procedures. In this project we have developed a low cost, high performance, dedicated PET camera (maxPET) for mammary and axillary region imaging. The system consists of two 15x15 cm2 planar scintillation detector arrays composed of modular detectors operating in coincidence. The modular detectors are comprised of...

    2003-12-01

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is a rare variety of non-Hodgkin's lymphoma which originates from CD5+ B-cell population in the mantle zones of lymphoid follicles. Coexistence of such tumours in the axillary lymph nodes with invasive breast cancers without prior history of adjuvant chemotherapy or radiotherapy has not been previously reported in literature. Case report We report a rare case of breast cancer co-existing with stage I mantle cell lymphoma of the ipsilateral axillary lymph node detected fortuitously by population screening. Conclusion Though some studies have tried to prove breast carcinomas and lymphomas to share a common molecular or viral link, more research needs to be done to establish whether such a link truly exists.

  20. The Accuracy of Sentinel Lymph Node Biopsy Compared with Axillary Lymph Node Dissection in Breast Cancer

    Directory of Open Access Journals (Sweden)

    Abdolrasul Talei

    2011-10-01

    Full Text Available Background: Sentinel lymph node biopsy is used as an accurate staging procedure to detect early breast cancer. Several studies have documented that sentinel lymph node biopsy can accurately determine the status of axillary nodes. Sentinel node biopsy offers the advantage of accurately staging the axilla and eliminating the need for a full axillary dissection for patients who have a negative sentinel node. The aim of this study is to determine the predictors of non-sentinel lymph node metastasis by sentinel node biopsy.Methods: In this study, all patients (n=88 who underwent sentinel node biopsy for invasive breast cancer from June 2005 to June 2010 in Shahid Faghihi Hospital, Shiraz, Iran were enrolled. We reviewed the medical files of patients and their tumor characteristics. Statistical analysis was performed to determine whether any of thesecharacteristics alone could accurately predict the remaining non-sentinel node status. SPSS statistical package was used.Results: The mean age of the patients was 46.1 years. Tumor size was 2.73 cm. Of the 88 patients who underwent complete axillary node dissection, 34 had metastases in the non-sentinel nodes, with a mean of 4 positive non-sentinel nodes in each patient. Statistically, neither the patient’s age nor the clinicopathological features of the tumor were significantly associated with non-sentinel node metastases (all: P>0.05.Conclusion: Our study shows that neither the primary tumor characteristics nor the size of metastasis in the sentinel lymph node can predict the status of non-sentinel nodes. However, further investigation is necessary. Complete axillary node dissection shouldremain the most appropriate management for patients with positive sentinel lymph nodes.

    The purpose of our study was to assess the positive predictive value (PPV) of ultrasound (US)-guided fine-needle aspiration (FNA) and the cancer detection rate for incidentally detected abnormal axillary lymph node (LN) in patients who underwent screening US. We retrospectively reviewed 72 LNs of 69 patients (mean age, 44.9 years) who underwent US-FNA for incidentally detected abnormal axillary LNs on 50,488 screening US from January 2005 to December 2011. The PPV of US-FNA and the cancer detection rate were calculated. We evaluated US images for lymph node size, abnormal findings (hilum loss, eccentric cortical thickening, round shape, extranodal extension, or marked hypoechoic cortex), and mammography for the identification of abnormal LNs. The PPV of each finding was also calculated. The PPV of US-FNA and the cancer detection rate were 2.8% (2/72) and 0.004% (2/50,488), respectively. The mean (SD) measurements for long-axis, short-axis, and cortical thickening of the LNs were 14.9 (5.9) mm, 8.5 (3.5) mm, and 5.8 (2.8) mm, respectively. Of the positive LNs, US findings of hilum loss, eccentric cortical thickening, and extranodal extension were found, and each corresponding PPV was 6.3% (1/16), 1.8% (1/56), and 14.3% (1/7), respectively. The PPV of mammography was 14.3% (1/7). Our results suggest that the PPVs of US-FNA and the cancer detection rate for incidentally detected abnormal axillary LNs during screening US are too low to recommend axillary US during breast US screening and that follow-up is acceptable for abnormal LNs detected during screening breast US that do not have extranodal extension or are negative on mammography.

    2002-09-01

    To compare sonography and mammography in terms of their diagnostic value in breast cancer cases which initially presented as an axillary mass without a palpable mass or other clinical symptoms. Seven patients with enlarged axillary lymph nodes who first presented with no evidence of palpable breast lesions and who underwent both mammography and sonography were enrolled in this study. In six of the seven, the presence of metastatic adenocarcinoma was confirmed preoperatively by axillary needle aspiration biopsy; in four, subsequent sonographically guided breast core biopsy performed after careful examination of the primary site indicated that primary breast cancer was present. In each case, the radiologic findings were evaluated by both breast sonography and mammography. Breast lesions were detected mammographically in four of seven cases (57%); in three of the four, the lesion presented as a mass, and in one as microcalcification. In three of these four detected cases, fatty or scattered fibroglandular breast parenchyma was present; in one, the parenchyma was dense. In the three cases in which lesions were not detected, mammography revealed the presence of heterogeneously dense parenchyma. Breast sonography showed that lesions were present in six of seven cases (86%); in the remaining patient, malignant microcalcification was detected at mammography. Final pathologic examination indicated that all breast lesions except one, which was a ductal carcinoma in situ, with microinvasion, were infiltrating ductal carcinomas whose size ranged from microscopic to greater than 3 cm. At the time of this study, all seven patients were alive and well, having been disease free for up to 61 months after surgery. In women with a palpable axillary mass confirmed as metastatic adenocarcinoma, breast sonography may be a valuable adjunct to mammography.

    Axillary hyperhidrosis poses a serious problem to the affected patients. So far, the conservative measures employed seem to be disappointing, operations with axillary skin excision, undermining and/or skin reconstruction may cause secondary functional and cosmetic problems, whereas botulinum A toxin injections need to be repeated frequently. The aim of this study was to establish the safety, efficacy, and durability of subdermal (subcorial) suction sweat gland curettage in the treatment of axillary hyperhidrosis. So far, the method seems to be devoid of possible risks and drawbacks. In the last 4.5 years, 15 patients with axillary hyperhidrosis were operated on with the use of liposuction tools. First operations were performed in general anesthesia, then in tumescent anesthesia. The procedure of suction curettage was performed with the use of 3- to 4-mm wide liposuction cannulas. The patients were closely monitored during early stages of the healing process; then they were evaluated at 1 and 3 months, and finally at 1-4 years of the operation, when they were asked to assess the effects of the operation. Four patients had recurrence of the disease within 3 months; three of them were reoperated on, with good result. At 1-4 years of the operation, all our responders (ten of 15 patients) stated that the disease had completely subsided. The following complications were observed during the process of healing: hematomas, transient skin unevenness, and partial skin flap necrosis. In conclusion, subdermal suction curettage seems to be superior to botulinum A toxin injections by the effect durability, and to the surgical methods with skin excision and undermining by the probably lower complication rates.

    Beneficial health properties of garlic, as well as its most common adverse effect - distinctive breath odour - are well-known. In contrast, analogous research on the effect of garlic on axillary odour is currently missing. Here, in three studies varying in the amount and nature of garlic provided (raw garlic in study 1 and 2, garlic capsules in study 3), we tested the effect of garlic consumption on the quality of axillary odour. A balanced within-subject experimental design was used. In total, 42 male odour donors were allocated to either a "garlic" or "non-garlic" condition, after which they wore axillary pads for 12 h to collect body odour. One week later, the conditions were reversed. Odour samples were then judged for their pleasantness, attractiveness, masculinity and intensity by 82 women. We found no significant differences in ratings of any characteristics in study 1. However, the odour of donors after an increased garlic dosage was assessed as significantly more pleasant, attractive and less intense (study 2), and more attractive and less intense in study 3. Our results indicate that garlic consumption may have positive effects on perceived body odour hedonicity, perhaps due to its health effects (e.g., antioxidant properties, antimicrobial activity).

    We wanted to investigate the ability of breast MR imaging to identify the primary malignancy in patients with axillary lymph node metastases and initially negative mammography and sonography, and we correlated those results with the conventional imaging. From September 2001 to April 2006, 12 patients with axillary lymph node metastases and initially negative mammography and sonography underwent breast MR imaging to identify occult breast carcinoma. We analyzed the findings of the MR imaging, the MR-correlated mammography and the second-look sonography. We followed up both the MR-positive and MR-negative patients. MR imaging detected occult breast carcinoma in 10 of 12 (83%) patients. Two MR-negative patients were free of carcinoma in the ipsilateral breast during their follow-up period (39 and 44 months, respectively). In nine out of 10 patients, the MR-correlated mammography and second-look sonography localized lesions that were not detected on the initial exam. All the non-MR-correlated sonographic abnormalities were benign. Breast MR imaging can identify otherwise occult breast cancer in patients with metastatic axillary lymph nodes. Localization of the lesions through MR-correlated mammography and second-look sonography is practically feasible in most cases.

    Patients with chronic lymphocytic leukemia (CLL) have an increased frequency of axillary lymphadenopathy. Pretreatment CT scans can be used to upstage patients at the time of presentation and post-treatment CT scans can reduce the number of complete responses. In the current clinical workflow, the detection and diagnosis of lymph nodes is usually performed manually by examining all slices of CT images, which can be time consuming and highly dependent on the observer's experience. A system for automatic lymph node detection and measurement is desired. We propose a computer aided detection (CAD) system for axillary lymph nodes on CT scans in CLL patients. The lung is first automatically segmented and the patient's body in lung region is extracted to set the search region for lymph nodes. Multi-scale Hessian based blob detection is then applied to detect potential lymph nodes within the search region. Next, the detected potential candidates are segmented by fast level set method. Finally, features are calculated from the segmented candidates and support vector machine (SVM) classification is utilized for false positive reduction. Two blobness features, Frangi's and Li's, are tested and their free-response receiver operating characteristic (FROC) curves are generated to assess system performance. We applied our detection system to 12 patients with 168 axillary lymph nodes measuring greater than 10 mm. All lymph nodes are manually labeled as ground truth. The system achieved sensitivities of 81% and 85% at 2 false positives per patient for Frangi's and Li's blobness, respectively.

    Full Text Available Background: Axillary lymph node status is the most important breast cancer prognostic factor. Preoperative axillary ultrasound examination (PAUS is used to triage patients for sentinel lymph node biopsy (SLNB or axillary lymph node dissection (ALND. We assessed the detection rate of lymph node metastases by PAUS in a screening unit and evaluated associations between clinicopathological factors and PAUS positivity. Patients and Methods: This was a single-centre retrospective analysis of data extracted from a hospital breast cancer database and clinical records. Clinical, radiological, and pathological and prognostic indices were compared between PAUS-positive and PAUS-negative patients subsequently found to have lymph node metastases on histopathological analysis. Results: Two hundred and two patients were eligible for analysis. 50.5% of lymph node-positive patients were correctly identified as PAUS positive. Patients with PAUS-positive lymph nodes had less favorable disease characteristics, namely clinically palpable lymph nodes, higher Nottingham prognostic (NPI index, high lymph node burden according to the European Society of Medical Oncology (ESMO group classification, and larger, grade 3 tumors with lymphovascular invasion and extranodal spread. Moreover, PAUS-positive patients had more macrometastases and lymph node involvement than PAUS-negative patients. Conclusion: PAUS-positive patients and PAUS-negative (SLNB-positive patients have different clinicopathological characteristics. The presence of LVI, extranodal spread, grade 3 histology, or large tumors with poor prognostic indices in PAUS-negative patients should be regarded with caution and perhaps prompt second-look ultrasound examination.

    Summary: Partial breast reconstruction using perforator flaps harvested from the lateral chest wall has become a well-established surgical technique recently. In the case of a partial mastectomy with an axillary lymph node dissection, there are 2 main defects; one is a partial breast defect and the other is an axillary dead space. To reconstruct the 2 separate defects with local flaps, basically 2 different flaps are needed, and usually, it is rather difficult to harvest 2 different local flaps in the adjacent area. To resolve this problem, we introduce the L-positioned perforator propeller flap (PPF). We used an L-positioned PPF on 2 female patients, aged 46 and 47 years old, who were suffering from breast cancer in the upper outer quadrant. The concept of this flap design is as follows: the partial breast defect is reconstructed with the longer lobe of the L-positioned PPF and the axillary defect is filled with the smaller lobe of the L-positioned PPF at the same time. The reconstruction time was 2 hours and 0 minutes and 1 hour and 46 minutes in each case. The patients were successfully provided with aesthetically acceptable breast reconstruction without postoperative complications. Moreover, both patients had consecutive postoperative radiotherapy on the reconstructed area without complications. With this flap design, it is possible for patients to have safe and aesthetic reconstruction with only 1 local flap and fewer invasive procedures.

    Full Text Available Background: The established methods of nerve location were based on either proper motor response on nerve stimulation (NS or ultrasound guidance. In this prospective, randomised, observer-blinded study, we compared ultrasound guidance with NS for axillary brachial plexus block using 0.5% bupivacaine with the multiple injection techniques. Methods : A total of 120 patients receiving axillary brachial plexus block with 0.5% bupivacaine, using a multiple injection technique, were randomly allocated to receive either NS (group NS, n = 60, or ultrasound guidance (group US, n = 60 for nerve location. A blinded observer recorded the onset of sensory and motor blocks, skin punctures, needle redirections, procedure-related pain and patient satisfaction. Results: The median (range number of skin punctures were 2 (2-4 in group US and 3 (2-5 in group NS (P =0.27. Insufficient block was observed in three patient (5% of group US and four patients (6.67% of group NS (P > =0.35. Patient acceptance was similarly good in the two groups. Conclusion: Multiple injection axillary blocks with ultrasound guidance provided similar success rates and comparable incidence of complications as compared with NS guidance with 20 ml 0.5% bupivacaine.

    Full Text Available The giant anteater (Myrmecophaga tridactyla, a mammal belonging to the order Xenarthra and family Myrmecophagidae, is an endangered species. For this reason, additional knowledge about its anatomy is of interest, especially the forelimb, which plays important roles in feeding and defense. The goal of this study was to learn more about the origin and distribution of the axillary nerve of Myrmecophaga tridactyla by studying two individuals (one male and one female that belong to the Research Laboratory of Wild Animals (UFU. The study material consisted of corpses fixed and preserved in 10% aqueous formalin solution. Dissection of the material followed standard procedures. In both animals, the axillary nerve was found in the ventral branch of the sixth cervical (C6 and seventh (C7 spinal nerve. This nerve showed symmetry in relation to its position in the two specimens and branched into the teres major, teres minor and deltoid muscles. In both specimens the axillary nerve originated in the cranial cutaneous branch of the lower leg.

    Full Text Available An optimal plant propagation method of Physalis angulata L., a medicinally important herbaceous plant species has been developed using axillary meristem explants. Shoot bud proliferation was initiated from axillary meristem explants cultured on MS medium supplemented with various concentrations of 0.5-2.5mg/L/(BAP/(Zeatin/(KIN. The maximum in vitro response of shooting frequency of explants (88.1% and shoots per explant (42 was achieved with medium containing 1.0mg/L BAP. Multiple shoot culture was established by repeated subculturing of the shoot buds of axillary meristems on shoot multiplication medium. Among the subculture media BAP in combination with 1.5mg/L (IAA+0.25mg/L(GA3 produced maximum shoots per explant (128±0.29 after two weeks of culture. Effective in vitro shoot elongation and rooting was achieved on 1.0mg/L(GA3 and 1.0mg/L(IBA, respectively. Most of the generated shoots were successfully transferred to soil under field conditions. The survival percentage of the transferred plants on soil was found to be 90 per cent.  This protocol can be used for commercial propagation and for future genetic improvement studies.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the value of real-time ultrasound (US guidance for axillary brachial plexus block (AXB through the success rate and the onset time. METHODS: The meta-analysis was carried out in the Anesthesiology Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. A literature search of Medline, EMBASE, Cochrane database from the years 2004 to 2014 was performed. The literature searches were carried out using medical subject headings and free-text word: "axilla", "axillary", "brachial plexus", "ultrasonography", "ultrasound", "ultrasonics". Two different reviewers carried out the search and evaluated studies independently. RESULTS: Seven randomized controlled trials, one cohort study and three retrospective studies were included. A total of 2042 patients were identified. 1157 patients underwent AXB using US guidance (US group and the controlled group included 885 patients (246 patients using traditional approach (TRAD and 639 patients using nerve stimulation (NS. Our analysis showed that the success rate was higher in the US group compared to the controlled group (90.64% vs. 82.21%, p < 0.00001. The average time to perform the block and the onset of sensory time were shorter in the US group than the controlled group. CONCLUSION: The present study demonstrated that the real-time ultrasound guidance for axillary brachial plexus block improves the success rate and reduce the mean time to onset of anesthesia and the time of block performance.

    Background. Acute otitis media [AOM] may affect the accuracy of tympanic temperature measurements. We aimed to compare tympanic temperature measurements in patients with AOM against control groups, as well as compare the tympanic temperatures with axillary thermometry. Methods. This is a prospective, observational study. Patients from pediatric outpatient and emergency clinics who were diagnosed as single-sided AOM were included consecutively in the study. Normal ears of patients and children having the same age and gender who were not diagnosed as AOM were also studied as controls. Results. In patients with AOM, infected ears had higher temperatures than normal ears with a mean of 0.48 ± 0.01°C. There was no significant difference between the right and left tympanic temperatures in control group. Compared with axillary temperature, the sensitivity of tympanic temperature in the infected ear was 91.7% and the specificity was 74.8%. Conclusion. Comparisons of axillary and tympanic temperatures in children with AOM during the active infection concluded higher tympanic temperatures in infected ears. We suggest that the higher tympanic temperatures, approximately 0.5°C in our study, in infected ears may aid in diagnosis of patients with fever without a source in pediatric clinics. PMID:27648079

    One thousand, four hundred and forty-six patients with carcinoma of the breast treated with Halsted mastectomy (167), Patey mastectomy (732), and conservative surgery with axillary dissection, either at the same time (340), or separately (207), were evaluated with regard to the number and distribution of axillary lymph nodes. A total of 29,378 were removed and examined, on average 20.3 per patient. The average number of nodes was 13.5 at the first level, 4.5 at the second and 2.3 at the third. The same number of nodes were removed in patients treated with extensive surgery, such as Halsted mastectomy and limited surgery such as lumpectomy and in independent axillary dissection. In 839 cases metastases were found in the axilla. The average number of involved nodes was 6.4. Out of 839 patients, the first level was the site of metastases in 828, the second level in 364 and the third in 187. When a single lymph node was involved, it was nearly always at the first level. In only 11 cases, were the second and/or third levels invaded without metastases at the first level. Therefore, the percentage of cases with skipping metastases was very low (1.3%). It appears from the present data that the spread of breast cancer to the axilla follows a regular pattern; the first level is invaded first, whilst in most cases, the second and third levels are involved only when the first is substantially affected.

    Objective: The purpose of this study was to evaluate the impact of the negative lymph node (LN) count on the survival of the breast cancer patients in early stage after the axillary dissection. Methods: The breast cancer patients with T1–2N0–1M0 stage between January 2001 and December 2005 in Jiangsu Cancer Hospital, who underwent the axillary LNs dissection, were enrolled in this study. We analyzed the data of these patients including information of follow-up and postop-erative pathological results. All patients were divided into two groups according to the axillary LN status and each group was divided into four subgroups according to the negative LN count. Cox regression analysis was performed to screen the patho-logical factor including the negative LN count on the survival and to compare the different negative LN count on the survival. Results: COX proportional hazard regression model showed that the survival of the breast cancer was significantly associ-ated with the negative LN count. In T1–2N0 group, when the negative LN count was 3 or less, 4 to 5, 6 to 9 and 10 or more, the median survival time was (82.6 ± 4.1) months, (101.5 ± 1.3) months, (104.7 ± 1.0) months, and (110.5 ± 0.9) months respectively (P < 0.05). In T1–2N1 group, when the negative LN count was 6 or less, 7 to 8, 9 to 10 and 11 or more, the median survival time was (95.4 ± 1.9) months, (101.8 ± 1.1) months, (104.9 ± 1.0) months, and (106.5 ± 0.9) months respectively (P < 0.05). Conclusion: The negative LN count can reflect the adequacy of the axillary dissection. Increasing negative LN count is independently associated with improved survival in pT1–2N0M0 or pT1–2N1M0 staging breast cancer patients. The negative LN count should be considered for incorporation into staging for breast cancer with the axillary LN dissection.

    乳腺癌手术腋窝处理有不同方式。作者提出采用医生触诊+2种影像学检查作为评估腋窝的方法。根据评估结果采用相应的腋窝处理方式。(1)腋窝评估阴性,只做前哨淋巴结活检(SLNB),前哨淋巴结(SLN)无转移则不做腋窝淋巴结清扫(ALND)。(2)腋窝评估倾向阴性,如果SLN阴性,则不做腋窝清扫。如果SLN阳性,做功能性腋窝清扫。(3)腋窝评估可疑阳性,功能性腋窝淋巴结清扫。如果多个淋巴结转移,需要做level1或level2的淋巴结清扫。(4)术前评估腋窝阳性,在腋窝反向制图(ARM)基础上做腋窝level 1、level2甚至level3水平的腋窝淋巴结清扫。尽量保留被蓝染的引流上肢的淋巴通路。%There are several surgical treatments in axillary of breast cancer. Author suggests that axillary assessment should be depend upon the doctor’s palpation and other two kinds of image inspection. On the base of the assessment, the different operative procedure should be selected. (1)Axillary estimate is negative, sentinel lymph node (SLN) biopsy (SLNB) is only done. If no metastasis is in SLN, don’t do axillary lymph node dissection (ALND). (2)Axillary estimate is apt to negative, firstly SLNB, if positive in SLN, functional axillary lymph node dissection (FALND) should be done. (3)Axillary estimate is inclined to positive, FALND should be selected. If multi-metastases would be found, the dissection to level 1 or level 2 needed. (4)Axillary estimate is positive, total ALND should be done at the basis of axillary reverse mapping. Blue-dyed lymphatic passageway draining the arm should be preserved as far as possible.

    Full Text Available Abstract Background The standard treatment of the axilla in breast cancer used to be an axillary lymph node dissection. An axillary lymph node dissection is known to give substantial risks of morbidity. In recent years the sentinel node biopsy has become common practice. Future randomized study results will determine whether the expected decrease in morbidity can be proven. Methods Before the introduction of the sentinel node biopsy, we conducted a study in which 180 women of 50 years and older with T1/T2 cN0 breast cancer were treated with breast conserving therapy. Instead of an axillary lymph node dissection regional radiotherapy was given in combination with tamoxifen (RT-group. The study group was compared with 341 patients, with the same patient and tumour characteristics, treated with an axillary lymph node dissection (S-group. Results The treatment groups were comparable, except for age. The RT-group was significantly older than the S-group. The median follow up was 7.2 years. The regional relapse rates were low and equal in both treatment groups, 1.1% in RT-group versus 1.5% in S-group at 5 years. The overall survival was similar; the disease free survival was significant better in the RT-group. Conclusion Regional recurrence rates after regional radiotherapy are very low and equal to an axillary lymphnode dissection.

    Performing angiography in the prone position is a difficult technique; however it is useful in some emergency situation. We experienced a 60 years old male who was performed lipoma excision on his back in his family doctor's clinic. Since massive arterial bleeding could not be controlled with manual astriction, he transferred to our hospital in prone position with hemodynamic instability. Operating field was not kept because of massive bleeding; there-fore surgical treatment was impossible. We planed emer-gency arterial embolization (AE) in prone position. Hence we chose the left radial artery for vascular access. The left subclavicle arteriography showed many major and minor feeding arteries from left subclavicular and axillary arteries and a massive extravasation of the contrast medium. Three major feeding arteries were performed AE with gelatin sponge and steel coils. After AE, massive bleeding was controlled.He could discharge from our hospital on the 5th hospital day without any complication. Arterial embolization for lifethreatening bleeding from subcutaneous hypervascular tumor in the prone position is first report to our knowledge,and it is extremely rare. However we thought that this tech-nique is useful for patients who could not turn in the supine position, e.g. massive bleeding during renal biopsy and penetrating trauma from back.

    The aims of this study were (1) to evaluate FDG PET/CT and CT for the detection of axillary lymph node metastases in breast cancer (BC) patients and (2) to evaluate FDG PET/CT as a pre-test for the triage to sentinel lymph node biopsy (SLNB) versus axillary lymph node dissection (ALND). The sensitivity, specificity, positive and negative predictive value (PPV, NPV), and accuracy of FDG PET/CT and CT for axillary lymph node metastases were determined in 61 patients (gold standard: histopathology). According to the equation NPV = specificity .(1-prevalence)/[specificity.(1-prevalence)+(1-sensitivity).prevalence] FDG PET/CT was evaluated as a triage tool for SLNB versus ALND. The sensitivity, specificity, PPV, NPV and accuracy of FDG PET/CT was 58,92,82,77 and 79% and of CT 46,89,72,71 and 72%, respectively. Patients with an up to {proportional_to}60% risk for axillary lymph node metastases appear to be candidates for SLNB provided that the axilla is unremarkable on FDG PET/CT. FDG PET/CT cannot replace invasive approaches for axillary staging but may extend the indication for SLNB. (orig.)

    Aim: To investigate whether the histopathological characteristics of primary breast cancer tumours could predict the likelihood of false-negative axillary ultrasound. Materials and methods: Screening and symptomatic patients were identified from pathology records and imaging and pathology records reviewed. True and false-negative axillary staging ultrasound groups were compared statistically in terms of tumour size, pathological type and grade, lymphovascular invasion, and oestrogen receptor (ER) status. Results: Of 155 women with normal ultrasounds, 45 (29%) were node positive at axillary surgery. Breast tumour size was significantly different with the average size smaller in the true-negative group: 21 versus 30 mm (p < 0.02). The histological type varied significantly between the groups, with more lobular carcinomas in the false-negative group [6/110 (5%) versus 6/45 (13%), p < 0.001]. The false-negative group was also more likely to show lymphovascular invasion in the breast [6/110 (5%) versus 14/45 (31%), p < 0.001]. There was no significant difference in tumour grade or ER status. Conclusion: The present study has found significant differences in tumour characteristics between women with true-negative and false-negative axillary staging ultrasound in terms of size, primary tumour histological type and presence of lymphovascular invasion. In particular, axillary ultrasound in primary lobular carcinoma may be less accurate and a negative result is more likely to be spurious than with primary ductal carcinomas.

    Full Text Available Introduction: Given the high prevalence of upper extremity fractures and increasing need to perform painless reduction in the emergency departments, the use of analgesic methods with fewer complications and more satisfaction appears to be essential. The aim of this study is comparison the nerve stimulator guided axillary block (NSAB with intravenous sedation in induction of analgesia for painless reduction of distal radius fractures. Methods: In the present randomized clinical trial, 60 patients (18-70 years of age suffered from distal radius fractures, were divided into two equal groups. One group received axillary nerve block by nerve stimulator guidance and the other procedural sedation and analgesia (PSA using midazolam/fentanyl. Onset of analgesia, duration of analgesic effect, total procedure time and pain scores were recorded using visual analogue scale (VAS and the outcomes were compared. Chi-squared and student t test were performed to evaluate differences between two groups. Results: Sixty patients were randomly divided into two groups (83.3% male. The mean age of patients was 31 ±0.7 years. While the onset of analgesia was significantly longer in the NSAB group, the mean total time of procedure was shorter than PSA (p<0.001. The NSAB group needed a shorter post-operative observation time (P<0.001. Both groups experienced equal pain relief before, during and after procedure (p>0.05. Conclusion: It seems that shorter post-operative monitoring time and consequently lesser total time of procedure, make nerve stimulator guided axillary block as an appropriate alternative for procedural sedation and analgesia in painless reduction of distal radius fractures in emergency department.

    The purpose of this study is to determine how often breast magnetic resonance imaging (MRI) brings additional information that influences management of patients with breast cancer concerning surgical treatment, axillary lymph node approach, and systemic therapy. From July 2004 to July 2005, 99 patients recently diagnosed with breast cancer in clinical stages 0, I, and II were prospectively evaluated about their therapeutic plans, at first based on usual protocol (physical examination, mammography and ultrasound) and next going through bilateral breast MR. Examinations were carried out at 1.5 T on five sequences of FSPGR 3D for 90 seconds (four post-gadolinium diethylenetriaminepenta acetic acid 0.16 mM/Kg). Parameters analyzed on MRI were extension of primary lesion; detection of multifocality, multicentricity, or contra lateral lesion; muscular or skin involvement; and presence of lymph node involvement. Pathologic confirmation of additional lesions was achieved by core or excisional biopsy. MRI made 69 additional findings in 53 patients. Fifty-one findings were true-positives (51/69 = 73.9%) including 16 larger single lesions; 18 cases of multifocality; 7 cases of multicentricity; 3 cases of contra lateral lesion; 5 cases of lymph node involvement (one of them involved medial thoracic chain); 1 with muscular involvement; 1 with skin involvement. MRI has changed previous management plans in 44.4% of 99 patients. We observed increase in mastectomies (26.8%) on axillary lymph node dissection (25%) and changes on systemic therapy (20.2%), all because of additional MRI true-positive findings. Breast MRI alters significantly the rate of mastectomy, the approach of axillary chain for staging, and the use of systemic therapy because of its accuracy in evaluating breast cancer local extent.

    In this proof-of-concept study we seek to demonstrate the delivery of fluorescent contrast agent to the tumor-draining lymph node basin following intraparenchymal breast injections and intradermal arm injection of micrograms of indocyanine green in 20 breast cancer patients undergoing complete axillary lymph node dissection. Individual lymph nodes were assessed ex vivo for presence of fluorescent signal. In all, 88% of tumor-negative lymph nodes and 81% of tumor-positive lymph nodes were fluorescent. These results indicate that future studies utilizing targeted fluorescent contrast agents may demonstrate improved surgical and therapeutic intervention.

All studies showed18F-fluorodeoxyglucose (FDG) uptake in the draining axillary lymph nodes close to the vaccination site, while low-dose CT revealed lymph nodes ranged between 0.5 cm and 1.2 cm at the same site. This potential pitfall in PET/CT should be borne in mind during current vaccination programmes. (orig.)

  14. Drug concentrations in axillary lymph nodes after lymphatic chemotherapy on patients with breast cancer

    International Nuclear Information System (INIS)

    Lymph node status is one of the decisive prognostic factors in breast cancer. Chemotherapy targeting regional lymphatic tissues has emerged as a promising therapy for the treatment of malignancies with a high tendency to disseminate lymphatically. The present study determined the drug concentrations in axillary lymph nodes after lymphatic chemotherapy (LC) in patients with breast cancer and compared the results with those receiving intravenous chemotherapy (VC) to investigate whether LC could improve the accumulation of anticancer drug in regional lymph nodes. Sixty patients with breast carcinoma confirmed by preoperative puncture-biopsy were divided into two groups at random. The LC group (n = 30) received a subcutaneous injection of 4 ml of carboplatin-activated carbon suspension, containing 20 mg of carboplatin, adjacent to the primary tumour. The VC group (n = 30) received an intravenous administration of an equal dose of aqueous carboplatin. At 1, 12, 24, 36 and 48 hours after administration, modified radical mammectomies were performed on 12 patients at each time point, with 6 from each group. Axillary lymph nodes were removed for pathological examination. The platinum concentrations in nodes were determined by Zeeman atomic absorption spectrometry. A total of 275 axillary lymph nodes were resected, with 154 in the LC group and 121 in the VC group. Of the 275 lymph nodes, 136 (49.5%) from 23 patients (38.3%) had histopathologically detected metastases. At 1, 12, 24, 36 and 48 hours after injection, the carboplatin concentrations in the LC group were 11.82 ± 3.50, 23.58 ± 7.34, 18.22 ± 4.93, 16.70 ± 5.15 and 14.62 ± 4.29 μg/g (means ± SD), respectively, whereas those in the VC group were 0.06 ± 0.02, 0.11 ± 0.05, 0.10 ± 0.02, 0.05 ± 0.02 and 0 μg/g, respectively. Significant differences were found in each corresponding comparison (P < 0.001). Lymph node metastasis was uncorrelated with drug concentration (P > 0.05). LC can effectively and

    The distribution of ofloxacin (OFLX) along the shaft of each of three hair types, i.e., head, axillary and pubic, was investigated and compared among five healthy male volunteers 1 to 4 months after ingestion of OFLX for 1 or 2 days (total dose, 200 or 600 mg). Five strands of each hair type were sectioned together into successive 0.5-cm lengths starting from the dermal end, over a length of ≤6 cm, and the OFLX concentration in each hair section was measured by high-pressure liquid chromatogr...

  16. In-vitro radiosensitivity and rapid propagation of potato through axillary bud culture

    International Nuclear Information System (INIS)

    The axillary buds of two varieties of potato, Cardinal and Ultimus, were cultured on MS medium supplemented with different concentrations and combinations of cytokinins, auxin and GA3 for their rapid propagation. The results indicated that combination: kinetin 0.5 + NAA 0.1 + GA3 0.5 mg/l proved to be the best for regeneration of maximum number of plantlets. Moreover, the mortality rates at 30 Gray dose in the varieties Cardinal and Ultimus were 41.6 and 58.3 percent respectively and hence this dose was considered to be the optimum for further mutation experiments in potato

    BACKGROUND: The value of level III axillary clearance is contentious, with great variance worldwide in the extent and levels of clearance performed. OBJECTIVE: To determine rates of level III positivity in patients undergoing level I-III axillary clearance, and identify which patients are at highest risk of involved level III nodes. METHODS: From a database of 2850 patients derived from symptomatic and population-based screening service, 1179 patients who underwent level I-III clearance between the years 1999-2007 were identified. The pathology, surgical details, and prior sentinel nodes biopsies of patients were recorded. RESULTS: Eleven hundred seventy nine patients had level I-III axillary clearance. Of the patients, 63% (n = 747) were node positive. Of patients with node positive disease, 23% (n = 168) were level II positive and 19% (n = 141) were level III positive. Two hundred fifty patients had positive sentinel node biopsies prior to axillary clearance. Of these, 12% (n = 30) and 9% (n = 22) were level II and level III positive, respectively. On multivariate analysis, factors predictive of level III involvement in patients with node positive disease were tumor size (P < 0.001, OR = 1.36; 95% CI: 1.2-1.5), invasive lobular disease (P < 0.001, OR = 3.6; 95% CI: 1.9-6.95), extranodal extension (P < 0.001, OR = 0.27; 95% CI: 0.18-0.4), and lymphovascular invasion (P = 0.04, OR = 0.58; 95% CI: 0.35-1). Lobular invasive disease (P = 0.049, OR = 4.1; 95% CI: 1-16.8), extranodal spread (P = 0.003, OR = 0.18; 95% CI: 0.06-0.57), and having more than one positive sentinel node (P = 0.009, OR = 4.9; 95% CI: 1.5-16.1) were predictive of level III involvement in patients with sentinel node positive disease. CONCLUSION: Level III clearance has a selective but definite role to play in patients who have node positive breast carcinoma. Pathological characteristics of the primary tumor are of particular use in identifying those who are at various risk of level III nodal

Our prospective study evaluated the effect of two different surgical techniques for ALND on postoperative morbidity. Patients were scheduled to undergo ALND. Patients in group 1 (n = 17 underwent the most common and standard technique of ALND, which uses sharp dissection of the tissue and subsequent electrocoagulation of bleedings. Patients in group 2 (n = 17 underwent a modified standard technique of ALND with clamping and ligatures of all resection margins. Postoperative wound secretion was quantified and patients were followed up for 6 months to assess long-term morbidity. The variations in surgical technique had no significant influence on the outcome variables. However, patients in group 2 showed a tendency to less wound secretion (713 versus 802 mL; P = nonsignificant, a decreased rate of immediate postoperative seromas (11.8 versus 23.5%; P = nonsignificant and less lymphedema after 3 months (29.4 versus 41.2%; P = nonsignificant.

    Tuberculosis is an opportunistic infection that carries substantial morbidity and mortality in renal transplant recipients. We report here about a 21 year-old man with a living related renal transplant from his mother who developed persistent extra-pulmonary tuberculosis. The disease showed aggressive invasion to the axillary and mediastinal regions with abscess formations, despite standard antituberculosis treatment. During the course of the disease, immunosuppressive therapy was stopped, and the patient received extraordinary doses of multiple antituberculosis drugs. The patient then showed an uneventful course with good clinical and radiological responses.

    Arteriopathy restricted to the popliteal artery, except in cases of atheroma, must indicate three of four unusual diagnoses: the trapped popliteal artery and the dessicating haematoma are anatomo-clinical entities that have been identified only relatively recently. The popliteal artery may be trapped by the medial gastrocnomius muscle, round the tendon of which the artery passes (totally or partially). This results in compression of the artery and eventually in thrombosis. Clinically, intermittent claudication is seen that may deteriorate and lead to gangrene of the toes. Arteriography makes it possible to diagnose the condition as the condition as the artery is considerably displaced inwards. Surgical correction is simple: sectioning of the tendon and repositioning of the artery. Dessicating haematoma of the popliteal artery is due essentially to atheroma, associated with medianecrosis. A "egg-timer" stenosis is found by arteriography and this condition also progresses towards thrombosis. Arterial restoration is called for, usually by bridging. PMID:1230799

    Axillary lymph node metastasis without breast involvement from ovarian cancer is rare. We report a case of a 68-year-old woman proven as ovarian serous papillary carcinoma and metastatic papillary carcinoma of the omentum on surgical diagnostic laparoscopy. In addition, a hypermetabolic lymph node was detected in left axilla and was considered a reactive benign lesion. Mammography and ultrasonography showed no focal lesion in both breasts, but ultrasonography-guided core needle biopsy for the lymph node revealed metastatic serous papillary carcinoma from ovarian origin. Even with a low incidence of axillary lymph node metastasis without breast involvement from ovarian cancer and only marginally elevated standardized uptake value in positron emission tomography, the possibility of metastasis at axillary lymph node in patients with known primary ovarian cancer must be considered.

  6. Breast lymphoscintigraphy for sentinel node identification in clinically axillary node negative breast cancer: A preliminary report of 35 cases

    International Nuclear Information System (INIS)

    Full text: Lymphoscintigraphy is a sensitive, minimally invasive method for identifying sentinel lymph node (SLN). It has been extensively validated in malignant melanoma, penile cancer and recently in breast cancer. The aims of this study were to analyze and determine the clinical value of lymphoscintigraphy in SLN localization in woman undergoing surgery for breast cancer and to evaluate the predictive value of SLN versus axillary lymph node status in these patients. Pre-operative breast lymphoscintigraphy were preformed in 35 female patients with breast cancer and clinically negative axillary node. Mean age was 52.8 years (range 38 to 73 years). Prior to surgery, 74 MBq of Tc-99m nanocolloid in 0.2 to 0.5 ml was injected intra-dermally over the tumor mass. Immediately after injection, anterior dynamic images were acquired for 20 minutes, followed by anterior and lateral views static images at 30 minute, 1 hour and 2 hour using single-head gamma camera until SLN visualized. The SLN location was marked externally on skin. All patients underwent standard modified radical mastectomy with axillary node dissection. All lymph nodes were examined carefully by a skilled histopathologist. SLNs were assessed by visual inspection of both dynamic and static images. Comparison of SLN and axillary lymph node histopathologic results was done in order to define the means of SLN biopsy's ability to reflect the final status of axilla. The mean size of the primary breast tumor mass was 2.54 cm (1.0 to 4.0 cm). In 20/35 (57.1%), the SLNs were visualized in 20-minute dynamic imaging. In 12 patients, the SLNs were seen after delayed imaging and/or repositioning the patient. Overall estimated SLN identification rate was 91.43%. Of those 32 cases in whom the SLNs were localized on lymphoscintigraphy, 9 cases were positive for metastatic tumors and the rest were negative for tumor involvement. Four out of these 9 cases, SLN was the only node that contained metastatic tumor cells and in 5

    A review of the literature shows that lymphoscintigraphy and sentinel node biopsy are feasible in patients with previous breast and axillary surgery and could be especially warranted because in these patients, lymphatic drainage might not include the axillary basin. We report a case of a woman with recurrent breast cancer after breast-conserving surgery. The patient was found to have metastases in the contralateral intramammary lymph nodes. Demonstrating that such patterns do occur after previous treatment for breast cancer carries implications for the staging and management of these patients. PMID:17386126

    Full Text Available Background: Adjuvant radiotherapy reduces nodal recurrence in metastatic melanoma. The purpose of this study was to examine the effects of adjuvant radiotherapy on in-field nodal control of melanoma metastatic to axillary and inguinal lymph nodes. Methods: The medical records of patients who received adjuvant radiotherapy from January 1, 2003, through December 31, 2011, at Mayo Clinic were reviewed. Results: In the 20 patients identified, the rates of 2-year overall survival, nodal control, and freedom from distant metastases were 53%, 54%, and 44%, respectively. Intensity-modulated radiotherapy was used in 15 patients (75% and 3-dimensional conformal radiotherapy in 5 (25%. Disease progression was documented in 13 patients, with a total of 10 distant metastases and 6 in-field nodal recurrences. Treatment complications occurred in 14 patients: lymphedema, 9; lymphedema and fibrosis, 1; lymphedema and wound dehiscence, 1; wound dehiscence, 1; lymphedema and seroma, 1; and lymphedema, seroma, and fibrosis, 1. Conclusion: Patients with axillary and inguinal nodal metastases from melanoma have poor overall survival. Surgery and adjuvant radiotherapy provided a 54% nodal control rate. No plexopathy or grade 3 lymphedema complications were seen; however, 20% developed wound dehiscence.

    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.

    OBJECTIVE To investigate the influence of axillary lymph node micrometastases and the microvessel count on the prognosis of patients with breast cancer. METHODS Forty-eight patients with breast cancer, who had no tumor cells in their regional lymph nodes based on conventional histopathologic examination, were re-examined with immunohistochemical LSAB techniques. H&E, anti-EMA, CK 19 and FVlII factor staining was used to identify tumor cells in both lymph nodes and tumor tissues and to count the microvessels. A total of 882 lymph nodes were examined. RESULTS Immunostaining-positive tumor cells were found in 9.0 %(79/882) of the dissected lymph nodes. The positive rates were not significantly different between a surviving group and a deceased group (P>0.05). The microvessel count was significantly higher in group that had died (P<0.001). CONCLUSION The lymph node micrometastases did not show any correlation with patients'survival, but the microvessel density had a negative correlation with the survival period in breast cancer patients who had negative axillary lymph nodes.

    Aim: To determine the diagnostic yield of each of three core passes when sampling abnormal lymph nodes in patients presenting with breast cancer. Materials and methods: All patients suspected of having breast cancer had axillary ultrasound as part of initial assessment. Radiologically abnormal nodes (cortical thickness >2.3 mm or round shape) were biopsied with three passes of a 22 mm throw 14 G core biopsy needle and sent for histopathology in separate numbered pots. Data were collected prospectively, and analysis performed on the data of 55 consecutive patients who had positive nodes on at least one core biopsy needle pass. Results: Of 55 patients with a positive node on core biopsy, tumour was noted in all three cores taken in 39 (70.9%). Lymph node metastasis was detected in 45 (81.8%) first core biopsies. With the first two cores taken, positive results were detected in 53 of 55 cases (96.4%). In both cases where tumour was only found on a third core biopsy pass, no lymph node tissue was present in the first two biopsy passes. Conclusion: Two well-directed 14 G core biopsy samples from an abnormal axillary node are adequate for diagnosis of breast cancer metastasis.

    Full Text Available INTRODUCTION: The use of ultrasound in regional anesthesia allows reducing the dose of local anesthetic used for peripheral nerve block. The present study was performed to determine the minimum effective concentration (MEC90 of bupivacaine for axillary brachial plexus block. METHODS: Patients undergoing hand surgery were recruited. To estimate the MEC90, a sequential up-down biased coin method of allocation was used. The bupivacaine dose was 5 mL for each nerve (radial, ulnar, median, and musculocutaneous. The initial concentration was 0.35%. This concentration was changed by 0.05% depending on the previous block; a blockade failure resulted in increased concentration for the next patient; in case of success, the next patient could receive or reduction (0.1 probability or the same concentration (0.9 probability. Surgical anesthesia was defined as driving force ≤2 according to the modified Bromage scale, lack of thermal sensitivity and response to pinprick. Postoperative analgesia was assessed in the recovery room with numeric pain scale and the amount of drugs used within 4 h after the blockade. RESULTS: MEC90 was 0.241% [R 2: 0.978, confidence interval: 0.20-0.34%]. No patient, with successful block, reported pain after 4 h. CONCLUSION: This study demonstrated that ultrasound guided axillary brachial plexus block can be performed with the use of low concentration of local anesthetics, increasing the safety of the procedure. Further studies should be conducted to assess blockade duration at low concentrations.

    Full Text Available OBJECTIVE: To determine the prevalence of sonographic abnormalities (SA in the axillary vein of patients with and without post-mastectomy lymphedema. METHODS: We studied a sample of 80 women, divided into two equal groups, with and without lymphedema, with B mode ultrasound, color and pulsed Doppler. The primary variable, SA, is defined as change in the venous diameter, parietal thickening, intraluminal images, compressibility, parietal collapse at inspiration and feature of the axillary venous flow on the operated side. Secondary variables were: stage of lymphedema, surgical technique, number of radio and chemotherapy sessions, limb volume, weight and age. The differences between the proportions in the groups were determined using the Chi-square test and / or Fisher's test. For continuous variables, we used the Mann-Whitney Test. To estimate the magnitude of the associations, we used the prevalence rate of SA in both groups as a measure of frequency, and as a measure of association, the prevalence ratio (PR obtained as a function of relative risk (RR and estimated by the test Mantel-Haenszel homogeneity test. We adopted the statistical significance level of 5% (p < 0.05. RESULTS: only the criterion "parietal thickening" was strongly associated with the lymphedema group (p = 0.001. The prevalence of SA was 55% in patients with lymphedema and 17.5% in the group without it, with difference in prevalence of 37.5%. CONCLUSION: the prevalence of SA was higher in patients undergoing mastectomy with lymphedema than in those without lymphedema.

    Full Text Available Background and Objectives. A prospective, randomized, controlled, double-blind clinical trial to assess the effect of tramadol and ketamine, 50 mg, added to ropivacaine in brachial plexus anesthesia. Methods. Thirty-six ASA physical statuses I and II patients, between 18 and 60 years of age, scheduled for forearm and hand surgery under axillary brachial plexus block, were allocated to 3 groups. Group R received 0.375% ropivacaine in 40 mL, group RT received 0.375% ropivacaine in 40 mL with 50 mg tramadol, and group RK received 0.375% ropivacaine in 40 mL with 50 mg ketamine for axillary brachial plexus block. The onset times and the duration of sensory and motor blocks, duration of analgesia, hemodynamic parameters, and adverse events (nausea, vomiting, and feeling uncomfortable were recorded. Results. The onset time of sensorial block was the fastest in ropivacaine + tramadol group. Duration of sensorial and motor block was the shortest in the ropivacaine + tramadol group. Duration of analgesia was significantly longer in ropivacaine + tramadol group. Conclusion. We conclude that when added to brachial plexus analgesia at a dose of 50 mg, tramadol extends the onset and duration time of the block and improves the quality of postoperative analgesia without any side effects.

    Summary A 32-year-old woman hospitalized for subarachnoid hemorrhage showed rare arterial variation on the right side with anomalous origins of the vertebral artery, aberrant subclavian artery and persistent trigeminal artery. Angiography showed the right vertebral artery to originate from the right common carotid artery, the right subclavian artery to arise separately from the descending aorta, and persistent trigeminal artery on the right side. The possible embryonic mechanism of this previously unreported variant combination is discussed. PMID:22005696

    2005-01-01

    Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. Removing the stenosis by revascularization to restore unobstructed blood flow to the kidney is known to improve and even cure hypertension/azotemia, but is associated with a significant complication rate. To visualize renal arteries with x-ray technique...

However, ALND remains standard management of the axilla when a tumor-positive sentinel lymph node is identified.Methods: We identified 460 patients with breast cancer (clinically T1/T2N0M0 from the database for 1999–2004. Patient age ranged from 26 to 81 (median 50 years. Patients who underwent mastectomy or breast-conserving surgery with or without ALND were compared for regional recurrence, disease-free survival, and overall survival.Results: Patients with ALND (n = 308 were compared with the no ALND group (n = 152. Five-year overall survival and disease-free survival were not significantly different between the two groups, while there was a significant difference between them for regional recurrence. Of the 152 patients who did not undergo axillary dissection, four developed ipsilateral axillary disease, most of whom were rescued by delayed axillary dissection. Further, the criterion for identifying lymphedema was used, ie, a 2 cm circumferential change at any measured location. As a result, the incidence of lymphedema in the ALND group was 12.7%, while it was not seen in the non ALND group.Conclusion: There is a possibility that ALND may be omitted for cT1/T2N0M0 breast cancer through a combination of hormone therapy and adjuvant chemotherapy.Keywords: breast cancer, axillary lymph node dissection

  3. Observation of the Primo Vessel Approaching the Axillary Lymph Node with the Fluorescent Dye, DiI

    Full Text Available The primo vascular system (PVS floating in lymph fluid has mostly been observed in large caliber ducts around the caudal vena cava and the thoracic duct of rabbits, rats, and mice. But the PVS has not been traced up to the lymph nodes. It has not been established whether the PVS leaves the lymph vessel through the lymph vessel wall or it enters the lymph nodes. Therefore, observing the PVS entering a lymph node, for example, the axillary node, is desirable. In the current work, we traced the PVS approaching up to the surface of axillary node of a rat. The method used for this study was based upon a method that was recently developed to detect the PVS in the lymph duct from the inguinal to the axillary nodes in the skin of a rat by injecting Alcian blue into the inguinal node. However, the Alcian blue blurred near the lymph nodes and tracing the PVS up to the lymph nodes has not been possible. The current method clearly showed the PVS approaching the axillary node.

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

    Background: Deodorant products prevent the growth and activity of the degrading apocrine gland bacteria living in the armpit. Common antibacterial agents in the market like triclosan and aluminum salts, in spite of their suitable antibacterial effects, increase the risk of Alzheimer's disease, breast and prostate cancers or induce contact dermatitis. Therefore, plant extracts possessing antibacterial effects are of interest. The aim of the present study was to verify the in vitro antimicrobial effects of different sage extracts against two major bacteria responsible for axillary odor, and to evaluate the deodorant effect of a silicon-based stick containing sage extracts in different densities in humans. Materials and Methods: Different fractions of methanolic extract of Salvia officinalis (sage) were evaluated on a culture of armpit skin surface of volunteers through agar microdilution antimicrobial assay. Then, randomized, double-blind placebo-controlled clinical trial with the best antibacterial fraction was conducted on 45 female healthy volunteers. Participants were treated with a single dose in four groups, each containing 15 individuals: Group 1 (200 μg/mL), 2 (400 μg/mL), 3 (600 μg/mL) of dichloromethane sage extract, and placebo (without extract). A standard sensory evaluation method for the evaluation of deodorant efficacy was used before, and two hours, four hours, and eight hours after single application of a deodorant or placebo (ASTM method E 1207-87 Standard Practice for the Sensory Evaluation of Axillary Deodorancy). Results: The data were analyzed with two factors relating to densities and time. In 45 participants with a mean [± standard deviation (SD)] age of 61.5±11.8 years, statistically significant within-group differences were observed before and two, four, and eight hours after deodorant treatment for groups 1, 2, and 3. Groups 1, 2, and 3 had a significantly smaller odor score than placebo after two, four, and eight hours (P deodorant

    Although axillary lymph node status is an important prognostic factor and axillary dissection is regarded as the gold standard for staging, it requires radical surgery which is accompanied by considerable postoperative problems such as lymphedema. This study was carried out to evaluate the diagnostic accuracy of preoperative positron emission tomography (PET) and intraoperative frozen biopsy of sentinel lymphadenectomy (SLND) in detecting axillary lymph node metastasis. We studied 18 patients who had preoperative PET and SLND for breast cancer in the Department of Surgery at Samsung Medical Center. They all had preoperative PET with a radiolabeled glucose analogue ([{sup 18}F]FDG) to visualize primary tumors and metastatic nodes. Isosulphan blue dye was used for intraoperative SLND. Frozen and permanent biopsies were then compared after full axillary dissection. In 18 cases, six had positive metastatic nodes in the permanent biopsy of full axillary dissection but were negative in three cases by preoperative PET. There was one false negative result by frozen biopsy of SLND which was later shown to be positive by permanent biopsy. The sensitivity and specificity of SLND and PET for detecting axillary node metastasis were 83, 100% and 50, 100%, respectively. Although both methods are good for axillary nodal status, the intraoperative frozen biopsy result of SLND was superior to preoperative PET in our preliminary study. (author)

    Full Text Available Abstract Background Differentiated thyroid cancer is usually associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual: only few cases were previously reported in the literature; there has been no report of axillary lymph node metastasis from follicular thyroid carcinoma. Axillary lymph node metastasis generally arises in the context of disseminated disease and carries an ominous prognosis. Case presentation Here we present a case of axillary lymph node metastasis in the context of disseminated differentiated thyroid cancer. The patient underwent near total thyroidectomy and neck and axillary lymph node dissection. A histopathological diagnosis of poorly differentiated follicular carcinoma with "signet ring cells" and Hürthle cell features was established. The patient received radioactive iodine therapy and TSH suppression therapy. Subsequently his serum thyroglobulin level decreased to 44.000 ng/ml from over 100.000 ng/ml. Discussion and Conclusion Currently there are only few reported cases of axillary node metastases from thyroid cancer, and to our knowledge, this is the first report on axillary lymph node metastasis from follicular thyroid carcinoma. "Signet ring cell" is a morphologic feature shared by both benign and, more rarely, malignant follicular thyroid neoplasm, and it generally correlates with an arrest in folliculogenesis. Our case is one of the rare "signet ring cells" carcinomas so far described.

    Objective To assess the effectiveness and safety of axillary dissection in old women with breast cancer.Methods All randomized controlled trials on axillary dissection in old woman were retrieved in the Cochrane Library, PubMed, EMBASE and Chinese Biomedical Literature Database. Meta-analyses were completed using RevMan 5.1.Results Three eligible randomized controlled trials (RCTs) including 5337 patients were involved. There were weak evidences in favor of axillary dissection in old woman. The meta-analysis showed that the overall survival (OS) in 1, 3, 5 and 7 years and the disease-free survival (DFS) in 1, 3 and 5 years were not statistically different between axillary dissection patients and non-axillary dissection patients. However there was a statistical difference in 7-year DFS.Conclusions Axillary dissection does not show a survival benefit in the old women with breast cancer. Therefore it is not well-founded to do axillary dissection in old women with breast cancer.

    Full Text Available Abstract Background Prone breast positioning reduces skin reaction and heart and lung dose, but may also reduce radiation dose to axillary lymph nodes (ALNs. Methods Women with early stage breast cancer treated with whole breast irradiation (WBI in the prone position were identified. Patients treated in the supine position were matched for treating physician, laterality, and fractionation. Ipsilateral breast, tumor bed, and Level I, II, and III ALNs were contoured according to the RTOG breast atlas. Clips marking surgically removed sentinel lymph nodes (SLNs were contoured. Treatment plans developed for each patient were retrospectively analyzed. V90% and V95% was calculated for each axillary level. When present, dose to axillary surgical clips was calculated. Results Treatment plans for 46 women (23 prone and 23 supine were reviewed. The mean V90% and V95% of ALN Level I was significantly lower for patients treated in the prone position (21% and 14%, respectively than in the supine position (50% and 37%, respectively (p p % of SLN clips was 47% for patients treated in the supine position and 0% for patients treated in the prone position (p % to SLN clips was 96% for women treated in the supine position but only 13% for women treated in the prone position. Conclusions Standard tangential breast irradiation in the prone position results in substantially reduced dose to the Level I axilla as compared with treatment in the supine position. For women in whom axillary coverage is indicated such as those with positive sentinel lymph node biopsy who do not undergo completion axillary dissection, treatment in the prone position may be inappropriate.

    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...... at diagnosis, increasing tumor size and increasing proportion of positive sentinel nodes in a multivariate analysis.

    2013-04-30

    In this paper, we proposed a mechanistic breast cancer survival model based on the axillary lymph node chain structure, considering lymph nodes as a potential dissemination arrangement. We assume a naive breast cancer treatment protocol consisting of exposing patients first to a chemotherapy treatment on r intervals at k-cycles separated by equal time intervals, and then they proceed to surgery. Our model, different from former ones, accommodates a quantity of contaminated lymph nodes, which is observed during surgery. We assume a generalised negative binomial survival distribution for the unknown number of contaminated lymph nodes after surgery, which, during an unknown period, may potentially propagate the disease. Estimation is based on a maximum likelihood approach. A simulation study assesses the coverage probability of asymptotic confidence intervals when small or moderate samples are considered. A Brazilian breast cancer data illustrate the applicability of our modelling.

    Confirmation of the perivascular position of the needle by the injection of cold saline may be helpful to the perivascular technique, since the elicitation of a paresthesia indicates the correct positioning of the needle. In this prospective, randomized study of 48 patients, we found a 100% incidence of successful block with saline at 8-11 degrees C compared to 75% in a control group with saline at room temperature. The paresthesia induced by cold saline appears to be due to thermic stimulation and not to mechanical nerve compression by the saline entering the axillary space. A more frequent rate of correct positioning of the needle was found in the group with cold saline. PMID:7618724

    Between 1970 and April 1982, 592 women, with T/sub 1/, small T/sub 2/, N/sub 0/, N/sub 1/, M/sub 0/ breast cancer were managed by lumpectomy, axillary dissection and radiotherapy at the Institut Gustave Roussy (IGR). The overall cosmetic result and the degree of assymetry, fibrosis and telangiectasia of the treated breast were assessed by the radiation oncologist at each follow-up visit. The changes in these cosmetic parameters with time are shown. At 5 years the overall cosmetic result was excellent in 58%, good in 38% and fair or poor in 8%. A multivariate analysis was performed of the factors associated with a cosmetic defect. The most significant factors were tumour size, the presence of defect after surgery and the daily applied dose per fraction to the breast. Surgical and radiotherapy technique (especially alternate day fractionation) can significantly affect the cosmetic result obtained

    One distinctive feature of plant post-embryonic development is that plants can undergo reiterative growth and continuous organogenesis throughout their lifetimes. Axillary meristems (AMs) in leaf axils play a central role in this growth and differences in meristem initiation and development produce the diversity of plant architecture. Studies in the past 15 years have shown that several transcription factors (TFs) and phytohormones affect AM initiation. In this review, we highlight recent research using systems biology approaches to examine the regulatory hierarchies underlying AM initiation and the role of auxins and cytokinins in AM initiation and development. This research revealed a developmental mechanism in which phytohormone signals act with a gene regulatory network containing multiple TFs to contribute to the initiation of AMs. PMID:26925087

    Fluctuations in core body temperature beyond a narrow range are of concern as they indicate changed homeostasis. Thermoregulation remains a key aspect of neonatal care. New non touch method of measuring temperature may reduce infection rate and discomfort of neonates. Body temperature of neonates admitted in Neonatal Intensive Care Unit was measured using axillary digital thermometer and a handheld infrared non touch thermometer. The two methods did not agree well (mean difference = -0.5, 95% limits of agreement: [-2.3, 1.2]). The agreement was similar with a negligible difference when patients in open care warmers were excluded (mean difference = -0.6, 95% limits of agreement: [-2.3, 1.1]). As the accuracy is unsatisfactory, the said technology needs further improvement before it can be adapted for routine patient care. PMID:23999676

    We report a case of a 24-year-old man with complex shoulder defect on the right side following a road traffic accident. The patient was found to have a subclavian artery thrombosis in its second part with good collaterals ensuring limb viability. Free-flap reconstruction was not possible because of lack of recipient vascular pedicle nearby. Pedicled flaps routinely used for this area such as pectoralis major and latissimus dorsi myocutaneous flaps could not be used as their vascular pedicles arise from the second and third parts of the axillary artery distal to the subclavian artery thrombosis. The best option we could think was the trapezius myocutaneous flap as its vascular pedicle arises from the first part of the subclavian artery proximal to the thrombosis. This article further establishes the importance of knowing the vascular supply of flaps before their clinical application. In this case the trapezius flap acts as a lifeboat for coverage of the complex shoulder defect as its vascular supply is proximal to the site of subclavian artery thrombosis.

    In the production and breeding of Chrysanthemum sp., shoot branching is an important quality aspect as the outgrowth of axillary buds determines the final plant shape. Bud outgrowth is mainly controlled by apical dominance and the crosstalk between the plant hormones auxin, cytokinin and strigolactone. In this work the hormonal and genetic regulation of axillary bud outgrowth was studied in two differently branching cut flower Chrysanthemum morifolium (Ramat) genotypes. C17 is a split-type which forms an inflorescence meristem after a certain vegetative period, while C18 remains vegetative under long day conditions. Plant growth of both genotypes was monitored during 5 subsequent weeks starting one week before flower initiation occurred in C17. Axillary bud outgrowth was measured weekly and samples of shoot apex, stem and axillary buds were taken during the first two weeks. We combined auxin and cytokinin measurements by UPLC-MS/MS with RT-qPCR expression analysis of genes involved in shoot branching regulation pathways in chrysanthemum. These included bud development genes (CmBRC1, CmDRM1, CmSTM, CmLsL), auxin pathway genes (CmPIN1, CmTIR3, CmTIR1, CmAXR1, CmAXR6, CmAXR2, CmIAA16, CmIAA12), cytokinin pathway genes (CmIPT3, CmHK3, CmRR1) and strigolactone genes (CmMAX1 and CmMAX2). Genotype C17 showed a release from apical dominance after floral transition coinciding with decreased auxin and increased cytokinin levels in the subapical axillary buds. As opposed to C17, C18 maintained strong apical dominance with vegetative growth throughout the experiment. Here high auxin levels and decreasing cytokinin levels in axillary buds and stem were measured. A differential expression of several branching genes accompanied the different hormonal change and bud outgrowth in C17 and C18. This was clear for the strigolactone biosynthesis gene CmMAX1, the transcription factor CmBRC1 and the dormancy associated gene CmDRM1, that all showed a decreased expression in C17 at floral

    Trapped popliteal artery syndrome is relatively uncommon: the literature reports some 60 cases. The clinical picture is linked to compression of the popliteal artery by the gastrocnemius as it contracts, thus distorting the arterial route. The result is an interruption in the blood flow distally to the area involved due to stenosis of the blood vessel that is at first functional but becomes organic. PMID:3808379

    Background We reviewed the outcomes of reoperations for 29 patients (30 limbs) who had undergone occluded arterial bypass in the lower limbs from May 1996 to September 2005. Methods The 30 lower limbs of the 29 patients with arteriosclerotic obstruction received 44 reoperations, including thrombectomy alone (group T, 27) and inflow or outflow reconstruction plus thrombectomy (group C, 17). Among the 17 operations in group C, 17.6% (3/17) were inflow reconstructions involving the axillary-femoral (1), aorta-iliac (1) and aorta-femoral (1) arteries, and 76.4% (13/17) outflow reconstructions involving the femoral-popliteal bypass-tibial (8), femoral-tibial (1), femoral-popliteal bypass-popliteal arteries below the knee (2), and the femoral-popliteal bypass-tibial-peroneal trunk (2). One patient (1 limb) underwent both inflow and outflow reconstructions with an iliac arterial stent and a graft-popliteal anastomosis patch. Polytetrafluoroethylene (PTFE) grafts were used in the inflow or outflow reconstructions abve the knee. Autovenous grafts or autovenously combined PTFE grafts were used in the outflow reconstructions below the knee. Results The percentages of Fontaine stage III and IV before primary operation and reoperation were 60% (18/30) and 86.7% (26/30), respectively (P0.05). Among 42 reoperations, 19 failed within 1 month in groups T (16) and C (3) (P0.05). The rate of limb salvage was 64.29% (18/28). Conclusions The percentages of Fontaine stage III and IV before reoperation may be much higher than those before primary operation. Thrombectomy plus inflow/outflow reconstruction creates patency better than thrombectomy alone for re-occluded bypass.

    Background. FDG-PET/CT is increasingly being used for breast cancer staging. Its diagnostic accuracy in comparison to ultrasound as the standard non-invasive imaging modality for the evaluation of axillary lymph nodes has yet not been evaluated. Purpose. To retrospectively compare the diagnostic value of full-dose, intravenously contrast-enhanced FDG-PET/CT and ultrasound for the detection of lymph node metastases in breast cancer patients. Material and Methods. Ninety patients (one patient with a bilateral carcinoma) (89 women, one man; mean age, 55.5 {+-} 16.6 years) suffering from primary breast cancer underwent whole-body FDG-PET/CT and axillary ultrasound. The ipsilateral axillary fossa (n = 91) was evaluated for metastatic spread. The sensitivity, specificity, the positive predictive value (PPV), negative predictive value (NPV), and accuracy of both methods were calculated. The sensitivity and accuracy were statistically compared using the McNemar Test (P <0.05). Analyses were made on a patient basis. The number of patients with extra-axillary locoregional lymph node metastases exclusively detected by FDG-PET/CT was evaluated. For axillary lymph node metastases histopathology served as the reference standard. Results. The sensitivity, specificity, PPV, NPV, and accuracy of FDG-PET/CT for the detection of axillary lymph node metastases were 54%, 89%, 77%, 74%, and 75%, respectively. For ultrasound it was 38%, 78%, 54%, 65%, and 62%, respectively. FDG-PET/CT was significantly more accurate than ultrasound for the detection of axillary lymph node metastases (P = 0.019). There was no statistically significant difference between the sensitivity of both modalities (P = 0.0578). FDG-PET/CT detected extra-axillary locoregional lymph node metastases in seven patients (8%) that had not been detected by another imaging modality. Conclusion. Though more accurate compared to ultrasound for evaluating the axillary lymph node status FDG-PET/CT is only as sensitive as

  14. Dose to level I and II axillary lymph nodes and lung by tangential field radiation in patients undergoing postmastectomy radiation with tissue expander reconstruction

    International Nuclear Information System (INIS)

    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 (VD95%) was 23.9% (range 0.3 - 65.4%). The mean Ipsilateral Lung VD50% was 8.8% (2.2-20.9). Ipsilateral and contralateral expander volume correlated to Axillary VD95% in patients with bilateral reconstruction (p = 0.01 and 0.006, respectively) but not those with ipsilateral only reconstruction (p = 0.60). Ipsilateral Lung VD50% 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

    Full Text Available A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA following Doppler ultrasonographic (US and digitally-subtracted angiographic (DSA examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA was normal, but her left CCA was hypoplastic. The right internal artery (ICA was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis.

    Quantitative photoacoustics is emerging as a new hybrid modality to investigate diseases and cells in human pathology and cytology studies. Optical absorption of light is the predominant mechanism behind the photoacoustic effect. Therefore, a need exits to characterize the optical properties of specimens and to identify the relevant operating wavelengths for photoacoustic imaging. We have developed a custom low-cost spectrophotometer to measure the optical properties of human axillary lymph nodes dissected for breast-cancer staging. Optical extinction curves of positive and negative nodes were determined in the spectral range of 400 to 1000 nm. We have developed a model to estimate tissue optical properties, taking into account the role of fat and saline. Our results enabled us to select the optimal optical wavelengths for maximizing the imaging contrast between metastatic and noncancerous tissue in axillary lymph nodes.

  17. Bilateral axillary skin fold flaps used for dorsal thoracic skin wound closure in a dog : clinical communication

    Full Text Available A 10-year-old greyhound-cross dog was presented with a large, chronic skin wound extending over the interscapular region. The substantial skin defect was closed by making use of bilateral axillary skin fold flaps. It was possible to elevate the 2 skin flaps sufficiently to allow them to meet at the dorsal midline and thus facilitate complete closure of a large and awkwardly positioned wound. Small dorsal areas of the skin flaps underwent necrosis, but the resulting defects were closed without difficulty in a subsequent procedure. To the author's knowledge, this is the 1st clinical report of the use of bilateral axillary skin fold flaps in this fashion and describes an additional use of a versatile skin flap procedure.

    Full Text Available The use of staging imaging modalities with increased sensitivity has led to an increase in the incidence of detection of simultaneous malignancies. These cases require careful evaluation and discussion in a multidisciplinary setting to establish a treatment plan that optimizes the outcome with respect to each malignancy, particularly when treatment modalities overlap. We report a case of a patient diagnosed with axillary nodal diffuse large B-cell lymphoma (DLBCL in a community hospital where staging workup also revealed synchronous bilateral breast carcinomas. To our knowledge, this is only the second case report of a patient with three synchronous primary malignancies: bilateral breast carcinomas and axillary DLBCL. The only other similar case report had no role for radiation or chemotherapy in the management of the indolent follicular lymphoma.

    2006-01-01

    Full Text Available Introduction. Splanchnic artery aneurysms are uncommon but important vascular entity because nearly 25% of all cases present as surgical emergency. Objective. The purpose of our study was to present nine patients operated on at the Institute of cardiovascular diseases, as well as literature review of clinical presentation of the disease. Method. There were three splenic artery aneurysms, two celiac trunk aneurysms, and one aneurysm of the hepatic, superior mesenteric, inferior mesenteric and gastroduodenal artery. All patients were males, mean aged 67.5 years (60-73. In four patients, splanchnic artery aneurysm was discovered accidentally during routine ultrasonographic and angiographic examinations of the abdominal aorta. At that time, arteriovenous fistula was diagnosed in a patient No 1; it was formed after rupture of the splenic artery aneurysm into the splenic vein. Three aneurysms were manifested by abdominal pain and palpable pulsating abdominal mass. Two patients were admitted as urgent cases in the state of hemorrhagic shock and signs of intraabdominal bleeding due to rupture of the splenic and hepatic arteries. In 7 cases, diagnosis was made preoperatively by means of ultrasonography and angiography; in two patients, accurate diagnosis was confirmed during surgery. Results. Proximal and distal ligation of the artery was performed in a patient with rupture of the splenic aneurysm into the splenic vein that caused arteriovenous fistula. Gastroduodenal artery aneurysm was treated by trans-aneurysmatic ligation of its "entering" and "exiting" branches. Aneurysms of distal part of the superior mesenteric and splenic artery were resected without further reconstruction. Partial resection of the aneurysm and endoaneurysmorrhaphy was carried out in one case of celiac trunk aneurysm, and in another, after aneurysm resection, the restoration of blood flow through the hepatic and lienal artery was achieved by Dacron grafts. In a patient with the

    Methods. Isolated rabbit eyes (n=12 were perfused in situ with tyrode through the external ophthalmic artery. Effects of intra-arterial injections of NPY 200 μg/ml (Group A; n=6 and VIP 200 μg/ml (Group B; n=6 on the recorded pressure were obtained. For statistical analysis, Student's paired t-test and Fast Fourier Transform were used. Results. Spontaneous oscillations were observed before any drug administration in the 12 rabbit models. NPY produced an increase in total vascular resistance and a higher frequency and amplitude of oscillations, while VIP evoked the opposite effects. Conclusions. This study provides evidence of vasomotion in basal conditions in rabbit external ophthalmic artery. Concerning drug effects, NPY increased arterial resistance and enhanced vasomotion while VIP produced opposite effects which demonstrates their profound influence in arterial vasomotion.

    Transposition of the great artery is one of common congenital cardiac disease resulting cyanosis. Death occurs easily in untreated patients with transposition and intact ventricular septal defect (VSD) in infancy at a few days of age when posterior descending coronary artery (PDA) closed. Since there are 2 parallel circulations, flow from pulmonary to systemic circulation is necessary for systemic oxygenation, and Balloon atrial septostomy or prostaglandin infusion should be performed especially if patient do not have VSD. Although the advent of fetal echocardiography, it is difficult to diagnose the transposition of the great arteries (TGA) as abnormality of great vessels is relatively undistinguishable. The diagnosis of transposition is in itself an indication for surgery, and arterial switch procedure is performed in the case the left ventricle pressure remains more than 2/3 of systemic pressure. Preoperative diagnosis is important as associated anomalies and coronary artery branching patterns are important to decide the operative indication and timing of surgery.

    2008-08-01

    Full Text Available Abstract Background Histopathologic evaluation of surgical specimens is a well established technique for disease identification, and has remained relatively unchanged since its clinical introduction. Although it is essential for clinical investigation, histopathologic identification of tissues remains a time consuming and subjective technique, with unsatisfactory levels of inter- and intra-observer discrepancy. A novel approach for histological recognition is to use Fourier Transform Infrared (FT-IR micro-spectroscopy. This non-destructive optical technique can provide a rapid measurement of sample biochemistry and identify variations that occur between healthy and diseased tissues. The advantage of this method is that it is objective and provides reproducible diagnosis, independent of fatigue, experience and inter-observer variability. Methods We report a method for analysing excised lymph nodes that is based on spectral pathology. In spectral pathology, an unstained (fixed or snap frozen tissue section is interrogated by a beam of infrared light that samples pixels of 25 μm × 25 μm in size. This beam is rastered over the sample, and up to 100,000 complete infrared spectra are acquired for a given tissue sample. These spectra are subsequently analysed by a diagnostic computer algorithm that is trained by correlating spectral and histopathological features. Results We illustrate the ability of infrared micro-spectral imaging, coupled with completely unsupervised methods of multivariate statistical analysis, to accurately reproduce the histological architecture of axillary lymph nodes. By correlating spectral and histopathological features, a diagnostic algorithm was trained that allowed both accurate and rapid classification of benign and malignant tissues composed within different lymph nodes. This approach was successfully applied to both deparaffinised and frozen tissues and indicates that both intra-operative and more conventional

    Full Text Available Abstract Background Breast cancer is the first cause of cancer death among women and its incidence doubled in the last two decades. Several approaches for the treatment of these cancers have been developed. The axillary lymph node dissection (ALND leads to numerous morbidity complications and is now advantageously replaced by the dissection and the biopsy of the sentinel lymph node. Although this approach has strong advantages, it has its own limitations which are manipulation of radioactive products and possible anaphylactic reactions to the dye. As recently proposed, these limitations could in principle be by-passed if semiconductor nanoparticles (quantum dots or QDs were used as fluorescent contrast agents for the in vivo imaging of SLN. QDs are fluorescent nanoparticles with unique optical properties like strong resistance to photobleaching, size dependent emission wavelength, large molar extinction coefficient, and good quantum yield. Methods CdSe/ZnS core/shell QDs emitting around 655 nm were used in our studies. 20 μL of 1 μM (20 pmol QDs solution were injected subcutaneously in the anterior paw of healthy nude mice and the axillary lymph node (ALN was identified visually after injection of a blue dye. In vivo fluorescence spectroscopy was performed on ALN before the mice were sacrificed at 5, 15, 30, 60 min and 24 h after QDs injection. ALN and all other organs were removed, cryosectioned and observed in fluorescence microscopy. The organs were then chemically made soluble to extract QDs. Plasmatic, urinary and fecal fluorescence levels were measured. Results QDs were detected in ALN as soon as 5 min and up to 24 h after the injection. The maximum amount of QDs in the ALN was detected 60 min after the injection and corresponds to 2.42% of the injected dose. Most of the injected QDs remained at the injection site. No QDs were detected in other tissues, plasma, urine and feces. Conclusion Effective and rapid (few minutes detection of

    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.

    We investigated the CT (computed tomography) findings of metastatic lymph nodes (LNs), and we analyzed the diagnostic performance of multidetector row CT (MDCT) for detecting axillary LN metastases in patients with breast cancer. We investigated 59 patients who preoperatively underwent chest MDCT, and they underwent sentinel LN biopsy ro whole axillary LN dissection. We analyzed the morphologic features, the degree of enhancement and the delayed enhancement pattern. We classified the patients into the non-metastatic LN group and the metastatic LN group, and we calculated the diagnostic performance of MDCT for detecting metastatic LNs. When both the morphologic and quantitative criteria were consistent, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 58.1%, 100%, 100% and 68.3%, respectively, and MDCT accurately detected metastatic LNs in 2 patients that were false negative on sentinel LN biopsy. When the morphologic and quantitative criteria were consistent, the sensitivity, specificity, PPV and NPV were 87.1%, 53.6%, 67.5% and 78.9%, respectively. However, MDCT could not detect metastatic LNs, including two micrometastases (a total of 8 micrometastases) that were in each of four patients. MDCT can be used to perform the morphology and quantitative analysis of axillary LNs, and this modality has excellent specificity and a PPV for detecting metastatic LNs when the both of the diagnostic criteria are consistent.

    2002-01-01

    Full Text Available Correlation of standard path morphological prognostic parameters, primary tumor size and axillary nodal status with new prognostic factor in breast carcinoma: tumor suppressor gene p53 was analyzed. The studied sample included 65 women who underwent surgery for breast carcinoma at the Surgical Clinic of Clinical Center Banja Luka, from January 1st 1997 till January 1st 1999. Statistical data analysis was performed and correlation of prognostic factors was determined. The majority of authors in this field agree that the primary tumor size and axillary nodal status are the two most important prognostic factors. These factors are the best predictors of prognosis and survival of women who had the tumor and were operated on. Tumor markers were immunohistochemically determined in the last ten years and, according to the majority of authors, are still considered the additional or relative prognostic factors in breast carcinoma. Their prognostic value and significance increase almost daily. Most frequently determined tumor markers are bcl-2, pS2, Ki-67 and p53. There was a positive, directly proportional relationship between primary tumor size and tumor suppressor gene p53, but there was no positive correlation between the axillary nodal status and tumor suppressor gene p53. Significance of determination of new tumor markers as the prognostic factors was emphasized. These markers represent a powerful tool in the early detection and prevention of breast carcinoma.

    Secondary lymphedema is an acquired lymphatic disorder, which occurs because of damage to the lymphatic system from surgery and/or radiation therapy for cancer treatment. However, it remains unknown how post-nodal collecting lymphatic vessels (CLVs) draining to the surgical wound area change in response to lymphadenectomy. We investigated functional and architectural changes of inguinal-to-axillary internodal CLVs (ICLVs) in mice after a single axillary LN (ALN) dissection using near-infrared fluorescence imaging. Our data showed no lymph flow in the ICLVs draining from the inguinal LN (ILN) at 2 days post-surgery. External compression enabled visualization of a small segment of contractile fluorescent ICLVs, but not all the way to the axillary region. At day 6, abnormal lymphatic drainage patterns, including lateral and retrograde lymph flow via vessels branching off the ICLVs were observed, which started to disappear beginning 9 days after surgery. The administration of vascular endothelial growth factor (VEGF)-C into the wound increased resolution of altered lymphatic drainage. Lymphatic drainage from the base of the tail to the ILN did not significantly change over time. These results demonstrate that lymph flow in the CLVs is dramatically affected by a LN dissection and long-term interruption of lymph flow might cause CLV dysfunction and thus contribute to chronic lymphatic disorders.

    Although deception of floral pollinators is well known among orchids, the majority of animal-pollinated plants secure pollination by nectar rewards. The costs and benefits of nectar production remain poorly understood. Here, we developed a crossing design to introgress a low-nectar-volume locus of Petunia integrifolia into the genetic background of P. axillaris. The resulting introgression line resembled P. axillaris but produced only one-third of the nectar volume. When exposed simultaneously to low-nectar and wild-type P. axillaris plants, hawkmoth pollinators reduced their probing duration on low-nectar plants but otherwise did not show any signs of discrimination against these plants. However, reduced probing duration resulted in reduced seed production in the low-nectar plants despite their higher reproductive potential as evidenced by hand pollination. In line with this interpretation, we found a positive correlation between probing duration and seed set, and hawkmoth pollination of low-nectar plants that were manually supplemented with nectar to parental levels yielded seed sets similar to hand pollination. Thus, a simple self-serving pollinator behavior--the adjustment of probing time in response to nectar volume--may select against reducing nectar and protect many plant-pollinator mutualisms against a drift toward parasitism.

  15. Contralateral axillary disease in patients with previously treated breast cancer: manifestation of distant metastases or occult primary in contralateral breast?

    International Nuclear Information System (INIS)

    Contralateral axillary lymphadenopathy is occasionally seen in patients following disease in the ipsilateral breast. The aim of the study was to find out whether it might be a manifestation of an occult primary in the contralateral breast or manifestation of distant metastases from the previously treated carcinoma. A review of the records of 1331 breast cancer patients presented with recurrent disease and treated with surgery, radio-, chemo- or combined therapy showed that 36 patients presented with disease in the contralateral axilla during follow up. In 21 (1.6%) of them contralateral lymphadenopathy was the only symptom of the disease. 16 of them developed disease in the contralateral breast: in all cases the disease was locally advanced in nature indicative of diffuse involvement of the whole breast. In almost all 36 cases systemic disease developed soon after contralateral axillary disease was noted. These observations as well as pathological analysis suggested that contralateral axillary disease in our patients was an indication of metastases from the ipsilateral breast rather than manifestation of occult primary in the contralateral breast.

    Full Text Available Lymphangiogenesis and the expression of vascular endothelial cell growth factor C (VEGF-C in tumors have been considered to be causally promoting lymphatic metastasis. There are only a few studies on lymphatic metastasis in immunocompetent allograft mouse models. To study the relationship between VEGF-C-mediated lymphangiogenesis and axillary lymph node metastasis, we used two mouse mammary carcinoma cell lines; the BJMC338 has a low metastatic propensity, whereas the BJMC3879 has a high metastatic propensity although it originated from the former cell line. Each cell line was injected separately into two groups of female BALB/c mice creating in vivo mammary cancer models. The expression level of VEGF-C in BJMC3879 was higher than BJMC338. As the parent cell line, BJMC3879-derived tumors showed higher expression of VEGF-C compared to BJMC338-derived tumors. This higher expression of VEGF-C in BJMC3879-derived tumors was associated with marked increase in infiltrating macrophages and enhanced expression of lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1 reflecting increased tumoral lymphatic density and subsequent induction of axillary lymph node metastasis. Our mouse mammary carcinoma models are allotransplanted tumors showing the same axillary lymph node metastatic spectrum as human breast cancers. Therefore, our mouse models are ideal for exploring the various molecular mechanisms of cancer metastasis.

    Full Text Available PURPOSE: The study was to estimate the likelihood of axillary downstaging and to identify the factors predicting a pathologically node negative status after neoadjuvant chemotherapy (NAC with or without trastuzumab in HER2-positive breast cancer. METHODS: Patients with HER2-positive, stage IIa-IIIc breast cancer were enrolled. Axillary status was evaluated by palpation and fine needle aspiration (FNA before NAC. All patients received 4-6 cycles of PCrb (paclitaxel 80 mg/m2 and carboplatin AUC = 2 d1, 8, and 15 of a 28-day cycle, or paclitaxel 175 mg/m2 and carboplatin AUC = 6 every-3-week and were non-randomly administered trastuzumab (2 mg/kg weekly or 6 mg/kg every-3-week or not. After NAC, each patient underwent standard axillary lymph node dissection and breast-conserving surgery or mastectomy. And some patients received sentinel lymph node biopsy (SLNB before axillary dissection. RESULTS: Between November-2007 and June-2013, 255 patients were enrolled. Of them, 157 were confirmed as axillary node positive by FNA (group-A and 98 as axillary node negative either by FNA or impalpable (group-B. After axillary dissection, the overall pathologically node negative rates (pNNR were 52.9% in group-A and 69.4% in group-B. The ER-poor/HER2-positive subtype acquired the highest pNNR (79.6% in group-A and 87.9% in group-B, respectively and the lowest rate of residual with ≥4 nodes involvement (1.9% and 3%, respectively after PCrb plus trastuzumab. In multivariate analysis, trastuzumab added and ER-poor status were independent factors in predicting a higher pNNR in HER2-positive breast cancer. Forty-six tested patients showed that the ER-poor/HER2-positive subtype acquired a considerable high pNNR and axillary status with SLNB was well macthed with the axillary dissection. CONCLUSIONS: ER-poor/HER2-positive subtype of breast cancer is a potential candidate for undergoing sentinel lymph node biopsy instead of regional node dissection for

    The value of sentinel lymph node biopsy (SLNB) in post-neoadjuvant chemotherapy (NCT) patients is still controversial. We aimed to identify predictors and construct a nomogram for predicting the pathologically complete response (pCR) of axillary lymph nodes (ALNs) after NCT in node positive breast cancer patients. In total, 426 patients with pathologically proven ALN metastasis before NCT were enrolled, randomized 1:1 and divided into a training set and a validation set. We developed a nomogram based on independent predictors for ALN pCR identified by multivariate logistic regression as well as clinical significant predictors. The multivariate logistic regression analysis showed that hormone receptor (HR) status, human epidermal growth factor 2 (HER2) status and Ki67 index were independent predictors. The nomogram was thereby constructed by those independent predictors as well as tumor size and NCT regimens. The areas under the receiver operating characteristic curve of the training set and the validation set were 0.804 and 0.749, respectively. We constructed a nomogram for predicting ALN pCR in patients who received NCT. Our nomogram can improve risk stratification, accurately predict post-NCT ALN status and avoid unnecessary ALN dissection. PMID:27576704

    Emotional sweating and malodour production represent a relevant challenge to today's antiperspirant (AP) and deodorant products as stress in everyday life increases continuously. The aim of this study was to investigate stress-induced sweating in teenagers who are known to experience various stressful situations, e.g. exams at school or job interviews. To induce emotional sweating in 20 female and 20 male adolescents (16-18 years of age), we applied the Trier Social Stress Test (TSST), considered today to be the most reliable and standardized stress protocol. In this study, we demonstrate that the TSST induces high amounts of sweat and strong axillary malodour in the tested age group. Notably, male teenagers showed significantly higher stress-induced odour scores than female subjects, although no gender differences were detected concerning other physiological stress markers. Testing of a novel deodorant/AP product developed to specifically address the needs of adolescent consumers revealed excellent deodorant and AP efficacy under the challenging conditions of the TSST.

    We investigated swing-through axillary crutch gait (nonweight bearing on the left lower extremity) to determine the effects of gait speed, crutch length, and handle position on the forces exerted at the hands and on the moments exerted about the elbow joints. Ten healthy subjects, skilled in swing-through crutch gait, walked at three speeds using fitted crutches, at a fixed speed with four different crutch lengths, and at a fixed speed with four different handle positions. We collected ground reaction forces that exerted simultaneously on the right crutch and motion data with a force plate and three high-speed movie cameras. A biomechanical model was developed to calculate the forces exerted at the right hand and the moments exerted about the right elbow joint. Changing gait speed from slow to the normal gait of the subject showed statistically significant effects (p less than .05) on the forces at the hand. When we changed crutch heights for the subjects, we found no significant effects on the forces at the subjects' hands. Changing handle position significantly affected the moment at the elbow. Increasing the elbow-flexion angle above 30 degrees by raising the crutch handle 1 to 2 in resulted in a 100 percent increase in elbow-extension moment. We found a correlation of .82 between actual average elbow-flexion angle and elbow-extension moment. Changing gait speed or crutch length did not affect elbow moment.

  1. Auxin dynamics after decapitation are not correlated with the initial growth of axillary buds.

    One of the first and most enduring roles identified for the plant hormone auxin is the mediation of apical dominance. Many reports have claimed that reduced stem indole-3-acetic acid (IAA) levels and/or reduced basipetal IAA transport directly or indirectly initiate bud growth in decapitated plants. We have tested whether auxin inhibits the initial stage of bud release, or subsequent stages, in garden pea (Pisum sativum) by providing a rigorous examination of the dynamics of auxin level, auxin transport, and axillary bud growth. We demonstrate that after decapitation, initial bud growth occurs prior to changes in IAA level or transport in surrounding stem tissue and is not prevented by an acropetal supply of exogenous auxin. We also show that auxin transport inhibitors cause a similar auxin depletion as decapitation, but do not stimulate bud growth within our experimental time-frame. These results indicate that decapitation may trigger initial bud growth via an auxin-independent mechanism. We propose that auxin operates after this initial stage, mediating apical dominance via autoregulation of buds that are already in transition toward sustained growth. PMID:15965021

    The aim of this study was to define the impact of the presence of axillary nodal metastases on lymphatic mapping and sentinel lymph node (SLN) identification rate in patients with early breast cancer. Two hundred and forty-six lymphatic mapping procedures were performed with both labelled nanocolloid and blue dye, followed by SLN biopsy and/or complete axillary dissection. The following parameters were recorded: patient's age, tumour laterality and location, tumour size, tumour histology, tumour stage, tumour grade, lymphovascular invasion, radiotracer injection site (subdermal-peritumoural/peri-areolar), SLN visualisation at lymphoscintigraphy, SLN metastases (presence/absence, size) and other axillary metastases (presence/absence, number). Discriminant analysis was used to analyse the data. SLNs were identified by labelled nanocolloid alone in 94.7% of tumours, by blue dye alone in 93.5% and by the combined technique in 99.2%. Discriminant analysis showed the gamma probe SLN identification rate to be significantly limited by the presence of axillary nodal metastases. In particular, the size of SLN metastases and the number of other axillary metastases were the most important variables in reducing the gamma probe SLN identification rate (p=0.004 and p=0.002, respectively). On the other hand, high tumour grade was the only parameter limiting the blue dye SLN identification rate. The accuracy of lymphatic mapping with labelled nanocolloid is limited by the presence of axillary nodal metastases, and particularly by the degree of SLN tumoural invasion and the presence and number of other axillary nodal metastases. Neither of these elements seems to interfere with the blue dye identification rate. The combination of the two tracers maximises the SLN identification rate. (orig.)

Methods Axillary glands were gained in 27 cases of palmar hyperhidrosis with axillary hyperhidrosis, 11 cases of palmar hyperhidrosis and 8 cases of non-hyperhidrosis as control group. The number of axillary sweat glands was calculated by using HE staining and the expression of NKCC1 was detected respectively. Results The number of axillary sweat glands in three groups had no significant difference in statistics (HC=2.528 ,P>0.05). There was significant difference in the expression of NKCC1 between palamar hyperhidrosis patients with axillary hyperhidrosis and palmar hyperhidrosis patients (F=5.158,P0.05). Conclusion The increase of NKCC1 expression has the relationship with axillary hyperhidrosis of palmar hyperhidrosis patients with axillary hyperhidrosis, but has no relationship with the number of axillary sweat glands.

    Several studies have documented the prognostic significance of cell proliferation in breast cancer and its positive relationship with tumor grade, size, mitotic activity, hormonal and Her-2 status, and tumor progression. The Ki-67 antigen provides an accurate measure of the growth fraction of a tumor. Ki-67 expression in 103 primary breast carcinomas and their corresponding axillary lymph node metastases was correlated with age, tumor grade, size, estrogen receptor (ER), progesterone receptor (PgR), p53, epidermal growth factor receptor (EGFR), Bcl-2, Her-2 status, and patients' overall survival. Median Ki-67 expression in primary and metastatic tumors was 20% and 15%, respectively. Although there was no difference in overall survival (P = .65, log-rank test) between primary tumors with less than or at least 10% Ki-67 expression, there was significantly better overall survival when Ki-67 expression in lymph nodes was less than 10% (P = .040). For patients whose primary tumors exhibited Ki-67 expression less than 10%, most of their metastatic lesions had a similar low Ki-67; these patients had a favorable outcome. A small subgroup was noted to have a nodal Ki-67 of 10% or more and worse survival (P = .047). For patients whose primary tumors had a Ki-67 of 10% or more, most of their metastatic lesions had similar high Ki-67 values; however, a group of 12 patients had lymph node Ki-67 less than 10% and had a better overall survival (P = .092). Our results showed that measurement of Ki-67 in lymph node is superior to its evaluation in primary tumors. Identification of subgroups of patients in whom Ki-67 expression in lymph nodes differs from expression in primary tumor may assist in the selection of therapeutic options.

Growing the apple trees on their own rootsprovides some advantages in comparison with grafted trees. Micropropagation is the method of choice for plantlet production for thispurpose as well as for the establishment of healthy mother stock trees as a source of scions. The efficiency of axillary shoot proliferationwas examined on four media differing in plant growth regulators and their concentrations, and from three explant types: intact ordecapitated and defoliated microshoots placed vertically and one-nodal segments placed horizontally. All media consisted of Quoirin andLepoivre (QL macroelements and Murashige and Skoog (MS microelements. Furthermore, rooting efficiency on six different media/treatments was analyzed. Media with 1 mg/L 6-benzylaminopurine (BA or BA (0.5 mg/L + 1.5 mg/L kinetin (Kin produced similarnumber of microshoots per inoculated one (2.5 and 2.4, respectively. Medium with 1 mg/L thidiazuron (TDZ produced significantlyhigher number of shoots (3.6 but they were fasciated. Three different explant types also produced similar numbers of microshoots.High rooting efficiency (68.7%, a high number of roots per shoot (6.6 and the best quality of shoots were obtained in rooting mediumcontaining 2 mg/L of indole-3-butyric acid (IBA. An efficient method of shoot proliferation was established, and, since rooting was themost critical step, an efficient procedure for rooting apple cv. ‘Topaz’ was established.

  13. The use of Raman spectroscopy for the intra-operative assessment of axillary lymph nodes in breast cancer

    Horsnell, Jonathan

    Breast cancer remains a significant cause of morbidity and mortality. Assessment of the axillary lymph nodes is part of the staging of the disease. Advances in surgical management of breast cancer have seen a move towards intra-operative lymph node assessment that facilitates an immediate axillary clearance if it is indicated. Raman spectroscopy, a technique based on the inelastic scattering of light, has previously been shown to be capable of differentiating between normal and malignant tissue. These results, based on the biochemical composition of the tissue, potentially allow for this technique to be utilised in this clinical context. The aim of this study was to evaluate the facility of Raman spectroscopy to both assess axillary lymph node tissue within the theatre setting and to achieve results that were comparable to other intra-operative techniques within a clinically relevant time frame. Initial experiments demonstrated that these aims were feasible within the context of both the theatre environment and current surgical techniques. A laboratory based feasibility study involving 17 patients and 38 lymph node samples achieved sensivities and specificities of >90% in unsupervised testing. 339 lymph node samples from 66 patients were subsequently assessed within the theatre environment. Chemometric analysis of this data demonstrated sensitivities of up to 94% and specificities of up to 99% in unsupervised testing. The best results were achieved when comparing negative nodes from N0 patients and nodes containing macrometastases. Spectral analysis revealed increased levels of lipid in the negative nodes and increased DNA and protein levels in the positive nodes. Further studies highlighted the reproducibility of these results using different equipment, users and time from excision. This study uses Raman spectroscopy for the first time in an operating theatre and demonstrates that the results obtained, in real-time, are comparable, if not superior, to current

    Full Text Available INTRODUCTION: Ki-67 expression is a biomarker for proliferation. Its prognostic value is recognized in breast cancer (BC patients with negative axillary nodes, but is less clear in BC patients with positive axillary lymph nodes. METHODS: We retrospectively reviewed the medical records of 1131 Chinese BC patients treated from January 2002 to June 2007 and 450 patients met the inclusion criteria: positive nodes, adjuvant therapy, and complete biomarker profile (estrogen receptor (ER, progesterone receptor (PR, HER2, p53, Ki-67. Univariate and multivariate regression analysis were used to correlate biomarkers and tumor characteristics with metastasis free survival (MFS and overall survival (OS. RESULTS: Median follow-up time was 46 months (range 5-76 months. The Ki-67 expression was associated significantly with histological grade, ER, PR, HER2, and P53 status (P<0.05. Tumor stage, nodal stage, and ER status were independent prognostic factors for MFS. Ki-67 status was associated significantly with OS but not MFS. To determine whether the extent of LN involvement in the BC patients influenced the role of Ki-67 in survival rates, we compared these variables in patients with 1-3 positive lymph nodes (N1 to those of patients with ≥ 4 positive lymph nodes. Ki-67 status was an independent prognostic factor for MFS (Hazard Ratio, 3.27, P = 0.026 and overall survival (HR, 10.64, P = 0.007 in patients with 1-3 positive nodes (N1. CONCLUSIONS: The possibility that Ki-67 expression together with clinical factors can improve prediction of the prognosis of BC patients with 1 ∼ 3 positive axillary lymph nodes warrants further studies.

    Objective: Malignant axillary lymph nodes are an important predictor for breast cancer recurrence, but invasive dissection or biopsy is required for the diagnosis. We determined whether and how malignant nodes could be diagnosed preoperatively with magnetic resonance (MR) imaging. Materials and methods: We obtained MR images of all women evaluated for breast cancer at the Sun Yat-Sen University Cancer Center in 2010 and correlated the image characteristics of each axillary node with the pathologic diagnosis of the same node. Results: We analyzed 251 nodes (117 benign; 134 malignant) from 136 women (mean age, 44 years; range, 20–67). Mean diameter of the nodes was 18 mm (range, 5–58 mm). With pathologic diagnosis as the reference standard, MRI-based interpretations were 66.4% sensitive, 94% specific, and 79% accurate. Diameter, pathologic type, apparent diffusion coefficient value (ADC, b = 500 and 800), time-intensity curve (TIC) type of breast tumors correlated with node metastasis; ADC value (b = 500 and 800), TIC type, early enhancement rate, long-axis, short-axis, shape, margin and the location of nodes correlated with node metastasis (P < 0.001 for all). Tumor immunohistochemistry results for estrogen receptors, progesterone receptors, c-erbB-2, vascular endothelial growth factor, and Ki67 were not. An MRI-based lymph node scoring system based on these correlations had a specificity of 91%, a sensitivity of 93%, and an area under the ROC curve of 0.95 (P < 0.001). Conclusion: Metastatic axillary lymph nodes can be accurately diagnosed by MR in women with early breast cancer preoperatively and non-invasively. The scoring system appears to be superior to current methods.

    A 10-year-old greyhound-cross dog was presented with a large, chronic skin wound extending over the interscapular region. The substantial skin defect was closed by making use of bilateral axillary skin fold flaps. It was possible to elevate the 2 skin flaps sufficiently to allow them to meet at the dorsal midline and thus facilitate complete closure of a large and awkwardly positioned wound. Small dorsal areas of the skin flaps underwent necrosis, but the resulting defects were closed without...

    A diabetic male with severe autonomic neuropathy and recently discovered Hodgkin`s disease demonstrated bilateral uptake of [2-{sup 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.) With 1 fig., 9 refs.

    Accelerated ion beams is an excellent mutagen in plant breeding which can induce higher mutation frequencies and wider mutation spectrum than those of low linear energy transfer (LET) irradiations, such as X-rays (Okamura et al. 2003, Yamaguchi et al. 2003). Mutation breeding operation of two Saintpaulia ionahta cultivars using the method combining plant tissue culture technique and carbon ion beam irradiations were set out at Institute of Modern Physics from 2005 (Zhou et al. 2006). The effects of 960 MeV carbon ion beam and 8 MeV X-ray irradiations on regenerated shoots of Impatiens hawkeri from another kind of explants named in vitro axillary buds explants were studied recently. The biology endpoints in this study included relative number of roots (RNR), relative length of roots (RLR), relative height of shoots (RHS), relative number of nodes (RNN), survival fraction (SF) and morphology changes in the regenerated shoots. The experimental results showed that carbon ion beams inhibited the root and stem developments of axillary bud explants more severely than X-rays did. And the 50% lethal dose (LD50 ) is about 23.3 Gy for the carbon ion beam and 49.1 Gy for the X-rays, respectively. Relative biological effectiveness (RBE) of Impatiens hawkeri with respect to X-rays according to 50% SF was about two. Secondly, the percentage of shoots regenerated with malformed shoots including curliness, carnification, nicks in all Impatiens hawkeri axillary bud explants irradiated with carbon ion beam at 20 Gy accounted for 55.6%, while the highest number for the 40 Gy X-ray irradiation was 40%. Last, many regenerated shoots whose vascular bundle fused together were obtained only from explants irradiated with carbon ion beams. Based on the results above, it can be concluded that the effect of mutation induction by carbon ion beam irradiation on the axillary explants of Impatiens hawkeri is better than that by X-ray irradiation; and the optimal mutagenic dose varies from 20 Gy

    Although the third most frequent aneurysm in the abdomen, after aneurysms of the aorta and iliac arteries, and most frequent aneurisms of visceral arteries, splenic artery aneurysms are rare, but not very rare. Thanks to the new imaging techniques, first of all ultrasonography, they have been discovered with increasing frequency. We present a series of 9 splenic artery aneurysms. Seven patients were female and two male of average age 49 years (ranging from 28 to 75 years). The majority of afected women were multiparae, with average 3 children (ranging from 1 to 6). One patient had a subacute rupture, and 2 had ruptures into the splenic vein causing portal hypertension. The spleen was enlarged in 7 out of 9 patients. The average size of aneurysms was 3,2 cm (ranging from 2 to 8 cm). The preoperative diagnosis of splenic artery aneurysm was established in 6 patients while in 3 patients aneurism was accidentally found during other operations, during splenectomy in 2, and during the excision of a retroperitoneal tumour in 1 patient. Aneurysmectomy was carried out in 7 patients, while a ligation of the incoming and outcoming wessels was performed in 2 patients with arteriovenous fistula. Splenectomy was performed in 6 patients, while pancreatic tail resection, cholecystectomy and excision of the retroperitoneal tumor were performed in 3 patients. Additional resection of the abdominal aortic aneurysm with reconstruction of aortoiliac segment was performed in 2 patients. There were no mortality and the postoperative recovery was uneventful in all patients. PMID:16989145

    The ability of shoot tips from carnation (Dianthus caryophyllus L., var. Eolo) cultured in vitro to develop resistance to freezing in liquid nitrogen depends on the physiological state of the cell material and the pretreatment conditions. Regrowth rates close to 100% have been obtained with apical shoot tips isolated from 2 month-old stems, precultured on medium supplemented with sucrose (0.75M) and treated with dimethylsulfoxide (5% or more). Resistance of axillary shoot tips decreased progressively as a funtion of their distance from the apical shoot tip. During the development of the stem from axillary buds (obtained by cutting), progressive increases in the regrowth rate of frozen apices were noted, from 30% before cutting (axillary buds) to 98% after 3 weeks of culture.

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

    This study evaluated the accuracy of ultrasound-guided fine-needle aspiration cytology of the sonographically most suspicious axillary lymph node (US/FNAC) to select early breast cancer patients with three or more tumour-positive axillary lymph nodes. Between 2004 and 2014, a total of 2130 patients with histologically proven early breast cancer were evaluated and treated in the Noordwest Clinics Alkmaar. US/FNAC was performed preoperatively in all these patients. We analysed the results of US/FNAC retrospectively. Pathological axillary node status (sentinel node biopsy and/or axillary lymph node dissection) was used as reference standard. A total of 634 (29.8 %) of 2130 patients had axillary lymph node metastases on final histology. 248 node positive patients (11.6 %) had three or more positive lymph nodes. The accuracy of US/FNAC to detect three or more positive lymph nodes was 89.8 %, sensitivity was 44.8 %, specificity was 95.7 %, PPV was 58.1 %, and NPV was 92.9 %. This study shows a more than adequate accuracy of preoperative US/FNAC to detect three or more positive lymph nodes (89.8 %). However, when US/FNAC was chosen as the only axillary staging method, 6.4 % of all patients (false negative group) would have been undertreated and 3.8 % of all patients (false positive group) would have been overtreated according to the ACOSOG Z0011 criteria.

    Full Text Available BACKGROUND: Accurate detection and determination of axillary lymph node metastasis are crucial for the clinical management of patients with breast cancer. Noninvasive imaging methods including ultrasound (US, computed tomography (CT, or conventional magnetic resonance imaging (MRI are not yet accurate enough. The purpose of this study was to investigate the value of in vivo T2* in differentiating metastatic from benign axillary lymph nodes in patients with breast cancer. METHODOLOGY/PRINCIPAL FINDINGS: In this institutional review board approved study, 35 women with breast cancer underwent multi-echo T2* weighted imaging (T2*WI of the axillary area on a 3.0 T clinical magnetic resonance (MR imaging system. T2* values of pathologically proven benign and metastatic axillary lymph nodes were calculated and compared. Receiver operating characteristics (ROC analysis was conducted to evaluate the diagnostic ability. The areas under the ROC curve (AUCs and the confidence intervals (CIs were assessed. In total, 56 metastatic and 65 benign axillary lymph nodes were identified in this study. For metastatic lymph nodes, the average T2* value (55.96±11.87 ms was significantly longer than that of the benign lymph nodes (26.00±5.51 ms, P<0.05. The AUC of T2* in differentiating benign from metastatic lymph nodes was 0.993. The cut-off value of 37.5 milliseconds (ms gave a sensitivity of 94.6%, a specificity of 98.5%, a positive predictive value of 98.17 and a negative predictive value 95.54. CONCLUSIONS: In vivo T2* can differentiate benign from metastatic axillary lymph nodes in patients with breast cancer. The high sensitivity and specificity as well as the easiness suggest its high potential for use in clinical practice.

  7. Improved false negative rate of axillary status using sentinel lymph node biopsy and ultrasound-suspicious lymph node sampling in patients with early breast cancer

    International Nuclear Information System (INIS)

    The false negative rate of sentinel lymph node biopsy (SLNB) is 5-10%, and results in improper patient management. The study was to assess the value of ultrasound-suspicious axillary lymph node biopsy (USALNB) in patients with early breast cancer, and to compare SLNB combined with USALNB (SLNB + USALNB) with SLNB alone. From January 2010 to July 2013, 216 patients with early breast cancer were enrolled consecutively at the Department of Breast and Thyroid Surgery, Qianfoshan Hospital, Shandong University. All patients underwent wire localization of the suspicious node by color Doppler ultrasonography, followed by SLNB 2–3 hours later, suspicious node lymphadenectomy, and level ≥ II axillary dissection (as the gold standard). The predictive values of node status between SLNB + USALNB and SLNB alone were compared. The success rate of SLNB was 99.1% (214/216). After axillary dissection, 71 patients were confirmed with axillary lymph node metastases by pathological examinations. Eight false negatives were observed using SLNB alone, resulting in sensitivity of 88.7%, specificity of 100%, false negative rate of 11.3%, and false positive rate of 0% in predicting the axillary node status. SLNB + USALNB resulted in sensitivity of 97.2%, specificity of 100%, false negative rate of 2.8%, and false positive rate of 0%. The false negative rate of SLNB + USALNB was significantly different from that of SLNB alone (P = 0.031). SLNB + USALNB seems to be a low-risk procedure that might be useful in reducing the false negative rate of SLNB, improving the accuracy of axillary nodes evaluation in early breast cancer

    Arterial hypertension and cancer are two of the most important causes of mortality in the world; correlations between these two clinical entities are complex and various. Cancer therapy using old (e.g., mitotic spindle poisons) as well as new (e.g., monoclonal antibody) drugs may cause arterial hypertension through different mechanisms; sometimes the increase of blood pressure levels may be responsible for chemotherapy withdrawal. Among newer cancer therapies, drugs interacting with the VEGF (vascular endothelial growth factors) pathways are the most frequently involved in hypertension development. However, many retrospective studies have suggested a relationship between antihypertensive treatment and risk of cancer, raising vast public concern. The purposes of this brief review have then been to analyse the role of chemotherapy in the pathogenesis of hypertension, to summarize the general rules of arterial hypertension management in this field and finally to evaluate the effects of antihypertensive therapy on cancer disease.

    Boutouyrie, Pierre

    2011-09-10

    Arterial stiffness has emerged as an important marker of cardiovascular risk in various populations and reflects the cumulative effect of cardiovascular risk factors on large arteries, which in turn is modulated by genetic background. Arterial stiffness is determined by the composition of the arterial wall and the arrangement of these components, and can be studied in humans non-invasively. Age and distending pressure are two major factors influencing large artery stiffness. Change in arterial stiffness with drugs is an important endpoint in clinical trials, although evidence for arterial stiffness as a therapeutic target still needs to be confirmed. Drugs that independently affect arterial stiffness include antihypertensive drugs, mostly blockers of the renin-angiotensin-aldosterone system, hormone replacement therapy and some antidiabetic drugs such as glitazones. While the quest continues for \\'de-stiffening drugs\\

    Purpose: To evaluate the diagnostic reliability of CT-based sentinel lymph node (SLN) size criteria for selecting the candidates for direct axillary dissection without SLN biopsy and to determine the value of added contrast-enhanced study. Material and Methods: Breast cancer patients (n=107) underwent triple phasic (1-min, 3-min, 8-min) contrast-enhanced 5 mm-computed tomography (CT) of the breasts and axillae. In the CT image, the most inferior lymph node in the axilla was designated the SLN. Axillary status was judged based on SLN size criteria. CT density, enhancement rate, and peak enhancement time of each SLN were correlated with histopathological results. Results: SLN size criteria demonstrated a sensitivity of 76% and a positive predictive value of 95% in predicting SLN metastasis. The density values at each scanning time-point were significantly different for metastatic and non-metastatic SLN. However, their enhancement rates differed significantly only at 1 min. Their peak enhancement occurred primarily at 1 min. The use of contrast-enhancement criteria improved the predictive sensitivity, but failed to decrease the false-positive rate of the SLN size criteria. Conclusion: The enhancement rate at 1 min proved to be the most useful parameter in contrast-enhanced CT studies; however, it failed in improving the accuracy of the SLN size criteria.

    Objective: to evaluate the potential influence of trans axillary augmentation mammoplasty on future detection of sentinel lymph node. Materials and methods: prospective controlled study where 22 patients were selected and divided into two groups (post-mammoplasty and control) corresponding to 43 breasts (22 in the post-mammoplasty group and 21 in the control group) evaluated by lymphoscintigraphy immediately after periareolar {sup 99m}Tc-phytate injections. In the statistical analysis, p values < 0.05 were considered as significant. Results: all the breasts in the post-mammoplasty group presented lymphatic drainage to the axillary chain, with no difference as compared with the control group (p 0.488). The average number of hot lymph nodes was 1.27 {+-} 0.46 in the post-mammoplasty group, and 1.33 {+-} 0.58 in the control group (p = 0.895). The mean time required to visualize the first lymph node was 3.14 {+-} 4.42 minutes in the post mammoplasty group, and 5.48 {+-} 5.06 minutes in the control group (p 0.136). Conclusion: transaxillary augmentation mammoplasty did not affect the future detection of sentinel lymph node. (author)

    Two murine monoclonal antibodies that react with human breast cancer (3E1.2 and RCC-1) were labelled with {sup 131}iodine, and the radiolabelled antibody was injected into 40 patients, 36 of whom had breast cancer and the remaining four of whom had fibroadenoma (the normal, contralateral axilla was used as a control). Immunoscintigraphy had an overall sensitivity of 33% (23% with {sup 131}I-3E1.2 and 5% with {sup 131}I-RCC-1) for the detection of lymph node metastases and a specificity of 63% (67% with {sup 131}I-3E1.2 and 60% with {sup 131}I-RCC-1) with problems of non-specific uptake by presumably normal lymph nodes. The results of immunoscintigraphy obtained with {sup 131}I-RCC-1 (IgG) were superior to {sup 131}I-3E1.2 (IgM) although the accuracy of immunoscintigraphy using {sup 131}I-RCC-1 (56%) was not much better than preoperative clinical assessment (50%). However, there were cases when immunoscintigraphy using radiolabelled antibody (IgM or IgG) detected axillary lymph node metastases not suspected by clinical examination. Thus it appears that while immunoscintigraphy may be a useful adjunct to preoperative clinical assessment and is simple and safe, a major improvement in its accuracy is needed before it can replace axillary dissection and histological examination in the accurate staging of axilla in breast cancer.

    2001-01-01

    Objective: The aim of this study was to investigate Cathepsin-D (Cath-D) expression in different location and its relationship with prognosis in the axillary lymph nodes negative (ANN) breast cancer patients. Methods: Cath-D expression in 192 cases of breast carcinoma were examined by immunohistochemistry. Depending on different parts of expression, three evaluating methods were used, compared and analysed. Results: The positive rate of Cath-D expression in ANN breast cancer with poor prognosis group and axillary nodes positive (ANP) group were significantly higher than that in ANN breast cancer with good prognosis group (x2=23.20, P0.05). Cath-D expression in stromal cells had no statistical difference among the three groups (x2=1.56, P>0.05). When the Cath-D expression in cancer and stromal cells were counted into the positive rate, it was near the same (u1=0.47, u2=1.41, P>0.05). Conclusion: These results suggest that Cath-D expression is one of the powerful prognostic markers in ANN breast cancer. It's a reliable, practical, and convenient method to observe and evaluate Cath-D expression in cancer cells.

    Breast cancer is the most common malignancy in women worldwide. Fortunately, the overall survival is good. Therefore it is important to focus on the morbidities related to breast cancer treatment. One of the most dreaded morbidities is lymphedema. In 2007 the Axillary Reverse Mapping (ARM) was introduced to limit the invasiveness in the axilla during breast cancer surgery. It is hypothesized that ARM is able to limit the incidence of breast cancer related lymphedema (BCRL) considerably. This systematic review aims to answer the following research questions: (1) which approaches for ARM are described? (2) Is ARM surgical feasible and oncological safe? (3) Does ARM decrease the incidence of lymphedema after sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND)? In total 27 papers were retrieved using four electronic databases (PubMed, Web of Science, Medline and Cochrane clinical trials; assessed until May 13, 2015. The level of evidence of these studies was low (mostly level 3). Therefore the conclusions are that the ARM procedure is feasible although ARM-node rates have a broad range. Additionally, from a theoretical point there is a clear benefit from ARM in terms of lymphedema prevention. From a practical point there is little scientific data to support this due to the lack of studies; and especially because of the different methods and definitions for lymphedema used in the different studies.

    Objective To examine the expression of aquaporin (AQP) in axillary sweat glands of palmar hyperhidrosis patients with axillary hyperhidrosis and investigate its relationship with the pathogene-sis of palmar hyperhidrosis patients with axillary hyperhidrosis. Methods Axillary sweat glands were obtained in 34 cases of hyperhidrosis and 8 cases of non-hyperhidrosis as control group. The number of axillary sweat glands was calculated by using HE staining and the expression of aquaporins (AQP1, AQP3, AQP5) was detected by using immunochemical method respectively. The comparison was made between hyperhidrosis group and control group. Results The number of axillary sweat glands in two groups had no significant difference in statistics (Z=- 1.506, P>0. 05 ). Both groups had the expression of AQP5, and AQP1, AQP3 were undetectable; The AQP5 expression of axillary sweat glands in hyperhidmsis cases was significantly increased as compared with that in control group (Z=- 3. 523, P0.05);两组腋窝汗腺中均无AQP1、AQP3表达,AQP5在两组均有表达且在实验组中表达显著增强(Z=-3.523,P<0.05).结论 AQP1、AQP3不参与人体腋窝汗腺分泌;AQP5可能是参与人体腋窝汗腺分泌的主要水通道蛋白之一,其表达增强很可能是手汗症伴腋窝多汗患者的发病机制之一.

    Background Endovascular therapy is a treatment option for localized occlusion of the subclavian artery. In this report the long-term experience with 59 patients is presented.Methods Between June 1998 and September 2008, we used endovascular therapy to treat 61 subclavian arterial obstructive lesions in 59 patients (46 males and 13 females, 34-82 years of age with a mean age (61.9±11.0) years). Twenty patients (34%) had clinical symptoms due to vertebrobasilar insufficiency, 26 (44%) had disabling arm ischemia, and 13 (22%) had both symptoms. We performed all procedures under local anesthesia. The approaches were from the femoral artery (n=47), brachial artery (n=\\, involving bilateral subclavian disease) or both (n=11). Sixty stents were implanted. All patients were followed-up at 1,3, 6, and 12 months post-procedure, and annually thereafter. Results We achieved technical success in 58 (95.1%) arteries, all of which were stented. There were three technical failures; two were due to the inability to cross over an occlusion, necessitating the switch to an axillo-axillary bypass, and the third was due to shock after digital subtraction angiography and prior to stenting. Arterial stenosis pre- and post-stenting was (83.6±10.8)% and (2.5±12.5)% (P <0.01). Clinical success was achieved in 55 of the 59 patients (93.4%). Of the four clinical failures, three were technical and the remaining patient had a stent thrombosis. Systolic blood pressure difference between the two brachial arteries was (44.7±18.5) vs. (2.2±3.9) mmHg (P <0.01). Primary patency was 98% at 12 months, 93% at 24 months, and 82% at 5 years. Five patients were lost to follow-up by 12 months post-stenting. Significant recurrent obstruction developed in five patients with resumption of clinical symptoms. The overall survival rate was 98.2% at 12 months, 89.5% at 24 months, and 84.5% at 5 years.Conclusions Endovascular therapy for proximal subclavian arterial obstructive lesions is effective and

    Summary The trigeminal artery is an anastomosis between the embryonic precursors of the vertebrobasilar and carotid systems, and may persist into adult life. The association of the persistent primitive trigeminal artery (PTA) with cerebral aneurysm is well documented in the literature and, in general, aneurysms are located in the anterior circulation. We describe a patient who presented with a panencephalic Fisher III subarachnoid hemorrhage due to rupture of an intracranial aneurysm. Digital arteriography showed a saccular aneurysm in the middle third of the basilar artery, adjacent to the junction with a persistent trigeminal artery. She was submitted to endovascular treatment with embolization of the basilar artery aneurysm with coils. Aneurysms at the PTA junction with the basilar artery are rare. This paper describes a case of PTA associated with an aneurysm in the basilar artery at PTA junction and briefly reviews the literature. PMID:22005697

    In breast cancer, the number of lymph node metastases is the strongest predictor of outcome. However, histopathology may underestimate the frequency of metastasis. Here we compare automated molecular detection of cytokeratin 19 mRNA by one-step nucleic acid amplification (OSNA) with histopathology of single tissue sections for the staging of axillary lymph nodes in patients with breast cancer. Axillary lymph nodes were collected from 55 patients with primary breast cancer and sentinel lymph node (SLN) metastases. The central 1-mm portion of each node was processed for hematoxylin-eosin staining, and the remaining tissue was analyzed by OSNA. According to OSNA, histopathology misclassified 41.8% of patients as negative for axillary node metastasis (P=0.007). Of the individual nodes considered negative by histopathology, 4.5% contained micrometastases and 2.5% contained macrometastases according to OSNA. Furthermore, 80% of micrometastases identified by histopathology were reclassified as macrometastases by OSNA. Histopathology failed to identify 81.1% of nodes shown to contain metastasis by OSNA. However, OSNA yielded no false-negative results. On the basis of OSNA results, 3 patients were reclassified to a higher pathologic stage. The number of SLN and non-SLN metastases was unrelated according to OSNA (P=0.891). These results show that, compared with molecular detection, histopathology of single tissue sections significantly underestimates the frequency of axillary node metastases. We discuss the implications of these findings in light of current recommendations on the staging of breast cancer.

    Full Text Available Abstract Background Persistent diarrhea is a common endemic disease with high incidence among the Africans including Nigerians. It also represents a frequent opportunistic disease in people living with HIV. Diarrhea represents one of the most distressful and persistent symptoms of HIV/AIDS, which may or may not be accompanied by an infection. The leaves decoction of Baissea axillaries Hua (Apocynaceae is used by traditional herbalists in Edo state, Nigeria for the management of people living with HIV/AIDS. Determination of its antimicrobial activity and toxicological profile will provide supportive scientific evidence in favour of its continuous usage. Method Chemical and chromatographic tests were employed in phytochemical investigations. Inhibitory activities of aqueous and ethanolic extracts against clinical strains of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus faecalis were compared with Togamycin (Spectinomycin. Our report includes minimum inhibitory concentration (MIC against the test organisms. Toxicological evaluation was determined by administering 250 mg/kg and 500 mg/kg of extracts on male Wister rats for 14 days with normal saline as control. The kidneys, liver, heart and testis tissues were examined. Results Phytochemical studies revealed the presence of alkaloids, tannins, and cyanogenetic glycosides. The extracts inhibited the growth of Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus to varying extents, but only the ethanolic extract inhibited growth in Streptococcus faecalis. The LD50 of the extract in mice was above 5000 mg/kg body weight when administered intraperitoneally. Toxicological evaluation showed mere ballooning degeneration of the liver at 250 mg/kg while at 500 mg/kg there was tissue necrosis. The low and high doses showed ill-defined leydig cells in the testis and no remarkable changes in the heart and kidneys. Conclusion Extracts of Baissea axillaries have

    International Nuclear Information System (INIS)

    Role of (18(F)fluorine-18-labeled 2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography-computed tomography (PET-CT) in the evaluation of axillary lymph node involvement in T1T2N0 breast cancer and compare results with sentinel lymph node biopsy (SLNB). SLN was identified in 32 of 37 patients with an identification rate of 86.48% (32/37). With combined technique SLN identification rate was 100% (6/6) while with blue dye alone; it was 83.8% (26/31). Among 37 patients, 16 had axillary metastases of which 12 had macrometastases and four had micrometastases detected by immunohistochemistry (IHC). Of 12 patients with axillary macrometastases, skip metastases were present in two patients in whom SLN was negative and in two patients SLN was not identified, but axillary dissection showed metastases. PET-CT had shown sensitivity, specificity, negative predictive value and positive predictive value of 56%, 90%, 73%, and 81.8%, respectively. IHC of SLN detected four patients with micrometastases upstaging the disease by 11% (4/37). Because FDG PET-CT has a high specificity in the evaluation of axillary lymph node involvement in T1T2N0 breast cancer patients according to the results of this study if FDG PET-CT is positive in axillary lymph nodes, axillary lymph node dissection may be considered instead of SLNB

    Full Text Available Caliber-persistent artery (CPLA of the lip is a common vascular anomaly in which a main arterial branch extends to the surface of the mucous tissue with no reduction in its diameter. It usually manifests as pulsatile papule, is easily misdiagnosed, and is observed more frequently among older people, suggesting that its development may involve a degenerative process associated with aging; CPLA is also characterized by the loss of tone of the adjacent supporting connective tissue. Although the diagnosis is clinical, high-resolution Doppler ultrasound is a useful noninvasive tool for evaluating the lesion. This report describes the case of a 58-year-old male patient who complained of a lesion of the lower lip with bleeding and recurrent ulceration. The patient was successfully treated in our hospital after a diagnosis of CPLA and is currently undergoing a clinical outpatient follow-up with no complaints.

    Background {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) position emission tomography ((PET) safely predicts axillary status in patients with breast cancer, but is not sufficiently accurate in early breast cancer patients. This study analyzed the value of {sup 18}F-FDG PET/computed tomography (CT) with contrast enhancement in detecting axillary lymph node involvement in T1 breast cancer patients. Contrast-enhanced {sup 18}F-FDG PET/CT was performed within 20 days of surgery in 143 breast cancer patients with tumors {<=}2 cm in size. The patients underwent either axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB), and histopathology reports were used to provide the definitive diagnosis against which the contrast-enhanced {sup 18}F-FDG PET/CT study results were compared. The sensitivity, specificity, and negative and positive predictive values of contrast-enhanced {sup 18}F-FDG PET/CT in detecting axillary involvement were 70.0%, 92.2%, 88.8%, and 77.8%, respectively, in the entire series of 143 patients, with eight false-positive and 12 false negative results. The false-negative results were associated with the number of metastatic lymph nodes and the rate of FDG uptake. Contrast-enhanced {sup 18}F-FDG PET/CT cannot replace histologic staging using SLNB in patients with breast cancer, but {sup 18}F-FDG PET/CT increases the sensitivity for predicting axillary node metastasis, and allows for a selective approach to either ALND or SLNB, even in patients with T1 breast cancer.

    This experiment aims to determine the diagnostic value of diffusion-weighted imaging (DWI) in the differentiation of axillary inflammatory lymph nodes from metastatic lymph nodes in rabbit models in comparison with conventional magnetic resonance imaging (MRI). Conventional MRI and DWI were performed at 4 weeks after successful inoculation into the forty female New Zealand white rabbits' mammary glands. The size-based and signal-intensity-based criteria and the relative apparent diffusion coefficient (rADC) value were compared between the axillary inflammatory lymph nodes and metastatic lymph nodes, with histopathological findings as the reference standard. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of the aforementioned criteria and rADC value in differentiating the axillary inflammatory lymph nodes from metastatic lymph nodes. Thirty-two axillary inflammatory lymph nodes and 46 metastatic ones were successfully isolated and taken into pathological analysis. The differences of the aforementioned criteria between the two groups were not statistically significant (p > 0.05). However, the rADC value of the inflammatory lymph nodes (0.9 {+-} 0.14) was higher than that of metastatic ones (0.7 {+-} 0.18), with significant difference (p = 0.016). When the rADC value was chosen as 0.80, the area under the ROC curve is greater than all other criteria, and the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for differentiating two groups were 86.2%, 79.3%, 81.2%, 84.2%, and 85.6%, respectively. Diffusion-weighted imaging is a promising new technique for differentiating axillary inflammatory lymph nodes from metastatic lymph nodes. Compared with routine magnetic resonance sequences, DWI could provide more useful physiological and functional information for diagnosis.

    Full Text Available To determine the performance of intraoperative one-step nucleic acid amplification (OSNA assay in detecting sentinel lymph node metastases compared to postoperative histology taking into account breast cancer molecular classification and to evaluate whether the level of cytokeratin 19 mRNA copy number may be useful in predicting the likelihood of a positive axillary lymph node dissection. OSNA assay was performed in a prospective series of 903 consecutive sentinel lymph nodes from 709 breast cancer patients using 2 alternate slices of each sentinel lymph node. The remaining 2 slices were investigated by histology. Cytokeratin 19 mRNA copy number, which distinguishes negative cases (5000 copies, was compared to axillary lymph node dissection status and to the biological tumor profile. Concordance between OSNA and histopathology was 95%, specificity 95% and sensitivity 93%. Multiple Corresponce Analysis and logistic regression evidenced that positive axillary lymph node dissection was significantly associated with a higher cytokeratin 19 mRNA copy number (>5000; p<0.0001, HER2 subtype (p = 0.007 and lymphovascular invasion (p<0.0001. Conversely, breast cancer patients with cytokeratin 19 mRNA copy number <2000 mostly presented a luminal subtype and a negative axillary lymph node dissection. We confirmed that OSNA assay can provide standardized and reproducible results and that it represents a fast and quantitative tool for intraoperative evaluation of sentinel lymph node. Omission of axillary lymph node dissection could be proposed in patients presenting a sentinel lymph node with a cytokeratin 19 mRNA copy number <2000 and a Luminal tumor phenotype.

    We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left, passing the anterior to the pulmonary artery, and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm, so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.

    @@ 1 Introduction Many molecular factors have been demonstrated to interfere with cellular proliferation and programmed cell death. One of these factors is a recently discovered member of the "inhibitor of apoptosis protein(IAP)" called survivin. Survivin is abundantly expressed in most solid and hematologic malignancies, but undetectable in normal adult tissues. Interference with survivin function induces pleiotropic cell-division defects and apoptosis. Cytosolic thymidine kinase (TK) is a marker for proliferating cells and TK is one of several key enzymes involved in DNAmetabolism that phosphorylates thymidine to thymidine mono-phosphate. This study was aimed to detect the expression of suvivin and TK in breast cancer, and to explore a possible relationship between survivin expression and axillary lymph node metastasis.

    Full Text Available Introduction: Breast carcinoma is the most common malignant tumor and the leading cause of cancer death in women. In western countries, a sharp increase in the detection of breast carcinoma, largely due to widespread use of mammography, has recently led to a fall in breast cancer mortality. This, however, is not true for less developed countries, in which mortality continues to rise. Objective: The aim of this study was to acquire information about the extent and spread of breast carcinoma in our patients by grading the tumors, determining the tumor size, and axillary lymph node status, staging of the tumors and Nottingham Prognostic Index (NPI scoring on the available material. Materials and Methods: One hundred and twenty consecutive mastectomy specimens with axillary lymph node sampling removed for breast carcinoma and received in the section of histopathology, Aga Khan University, in the year 2005, were included in the study. Standard protocols were used for the processing of the specimens, and reporting was done using a standard format incorporating all relevant tumor parameters. NPI was applied to the cases. Results: Out of the 120 cases, 5 (4.17 were grade 1, 91 (75.83 were grade 2, and 24 (20% were grade 3. Also, 9 cases (7.5% were T1 (4 were T1b, and 5 were T1c; 53 (44.16% were T2; 50 (41.66% were T3; and 8 (6.66% were T4. Axillary lymph nodes were available in 107 cases. In 13 cases, no lymph nodes were recovered. Out of 107 cases 27 (25.23% lymph nodes were negative for metastases pN0; 29 (27.10% cases were pN1; 26 (24.30 were pN2; and 25 cases (23.36% were pN3. Extranodal spread was present in 56 (70% out of the 80 cases in which lymph nodes were positive. The average microscopic size of nodal metastasis was 1.7 cms. Significant statistical association was found between the number of positive nodes and perinodal extension (P = 0.001. Tumor necrosis was present in 76 out of 120 cases (63.33%. Vascular invasion was present in 43 out of

    Axillary buds of taro (Colocasia esculenta var. esculenta, Araceae) cultured on half strength Murashige-Skoog medium (HMS) containing taro extract (HMSTE) and 2, 4, 5-trichlorophenoxyacetic acid produce a compact, hard, slow growing callus which is not very active morphogenetically and produces only a few plantlets. When cultured on HMSTE plus 5 mg 1(-1) each of naphthaleneacetic acid and benzyl adenine (HMSNB) the buds produce a fast growing, friable and morphogenetically active callus. Meristematic regions form on the friable callus after 30 days on HMSNB. If transferred to HMSTE at this point the callus gives rise to plantlets. Addition of taro extract to the media is required for the culture of buds, induction of callus and plantlet regeneration.

    A subcutaneous painful left axillary nodule was clinically diagnosed as abscess. Fine-needle aspiration biopsy (FNAB) revealed smears full of mature neutrophils. Background was free of fibrinous necrotic material and degenerating and necrotic neutrophils, which is characteristic of abscess. No organisms were detectable on special staining, and culture was sterile. A cytological differential diagnosis of abscess or Sweet's syndrome (SS) was offered, and the latter was confirmed. SS, also known as acute febrile neutrophilic dermatosis, shows diffuse dermal neutrophilic infiltrate without vasculitis on biopsy. Our case is probably the first where SS was diagnosed on FNAB. SS is a differential diagnosis for painful skin nodules. FNAB smears of painful skin nodules that yield abundant neutrophils should be carefully evaluated for necrosis, fibrin and degenerated neutrophils. The absence of these in an appropriate clinical setting points towards a neutrophilic dermatosis like SS. PMID:26390119

    ATP-binding cassette C11 (ABCC11) is a plasma membrane protein involved in the transport of a variety of lipophilic anions. ABCC11 wild-type is responsible for the high-secretion phenotypes in human apocrine glands, such as that of wet-type ear wax, and the risk of axillary osmidrosis. We have previously reported that mature ABCC11 is a glycoprotein containing two N-linked glycans at Asn838 and Asn844. However, little is known about the role of N-linked glycosylation in the regulation of ABCC11 protein. In the current study, we investigated the effects of N-linked glycosylation on the protein level and localization of ABCC11 using polarized Madin-Darby canine kidney II cells. When the N-linked glycosylation in ABCC11-expressing cells was chemically inhibited by tunicamycin treatment, the maturation of ABCC11 was suppressed and its protein level was significantly decreased. Immunoblotting analyses demonstrated that the protein level of the N-linked glycosylation-deficient mutant (N838Q and N844Q: Q838/844) was about half of the ABCC11 wild-type level. Further biochemical studies with the Q838/844 mutant showed that this glycosylation-deficient ABCC11 was degraded faster than wild-type probably due to the enhancement of the MG132-sensitive protein degradation pathway. Moreover, the incubation of ABCC11 wild-type-expressing cells in a low-glucose condition decreased mature, glycosylated ABCC11, compared with the high-glucose condition. On the other hand, the protein level of the Q838/844 mutant was not affected by glucose condition. These results suggest that N-linked glycosylation is important for the protein stability of ABCC11, and physiological alteration in glucose may affect the ABCC11 protein level and ABCC11-related phenotypes in humans, such as axillary osmidrosis.

    The goal of this work was to examine the possible influence of periclavicular irradiation on outcome of breast cancer patients with 1-3 positive lymph nodes with special emphasis on late toxicity rates. Between 1997 and 2000, 235 breast cancer patients (T1-2, 1-3 involved lymph nodes) were treated at our department following breast conservative surgery: 139 patients (59.1%) had one, 62 patients (26.4%) two, and 34 patients (14.5%) three positive lymph nodes. Extracapsular spread (ECS) was described in 72 patients (30.6%). There were 67 patients (28.5%) who received additional radiotherapy to the ipsilateral periclavicular lymph nodes (PCLNI), while 168 patients did not (noPCLNI). Patients were re-examined or contacted by phone with regard to treatment-related late effects. After a median follow-up of 78 months (range 7-107 months), 22 patients (9.4%) developed local, 9 (3.8%) axillary, 4 periclavicular (1.7%), and 41 distant failure (17.4%). The actuarial 8-year locoregional recurrence-free (LRRFS), disease-free (DFS), and overall survival rates (OS) were 83%, 67%, and 74%, respectively. Survival data for the PCLNI vs. noPCLNI group were 72% vs. 89% (p = 0.3), 56% vs. 73% (p = 0.4), and 86% vs. 70% (p = 0.3), respectively. No higher toxicity rates were reported in the PCLNI group compared to the noPCLNI group. We could not demonstrate any difference in outcome in breast cancer patients with 1-3 positive axillary lymph node metastases with or without periclavicular lymph node irradiation. In addition, patients with PCLNI did not complain about higher rates of late toxicities. However, patients with ECS, which may predict for locoregional failure, may benefit from adjuvant periclavicular irradiation. (orig.)

    Objective: To explore the effects of postmastectomy radiotherapy (PMRT) on the locoregional failure-free survival (LRFFS) and overall survival (OS) of breast cancer patients under different tumor stages and with one to three positive axillary lymph nodes (ALNs). Methods: We conducted a retrospective review of 527 patients with one to three positive lymph nodes who underwent modiifed radical or partial mastectomy and axillary dissection from January 2000 to December 2002. hTe patients were divided into the T1-T2 N1 and T3-T4 N1 groups. hTe effects of PMRT on the LRFFS and OS of these two patient groups were analyzed using SPSS 19.0, Pearson’s χ2-test, Kaplan-Meier method, and Cox proportional hazard model. Results: For T1-T2 N1 patients, no statistical signiifcance was observed in the effects of PMRT on LRFFS [hazard ratio (HR)=0.726; 95% conifdence interval (CI): 0.233-2.265;P=0.582] and OS (HR=0.914; 95% CI: 0.478-1.745;P=0.784) of the general patients. Extracapsular extension (ECE) and high histological grade were the risk factors for LRFFS and OS with statistical significance in multivariate analysis. Stratification analysis showed that PMRT statistically improved the clinical outcomes in high-risk patients [ECE (+), LRFFS:P=0.026, OS:P=0.007; histological grade III, LRFFS:P Conclusion: PMRT could reduce ECE (+), histological grade III-related LRR, and total mortality of T1-T2 N1 patients. T3-T4 N1 patients with ER/PR (-) could beneift from PMRT by improving LRFFS and OS. However, PMRT could only reduce LRR but failed to improve OS for T3-T4 N1 patients with ER/PR (+) who received endocrine therapy.

  9. Use of Axillary Deodorant and Effect on Acute Skin Toxicity During Radiotherapy for Breast Cancer: A Prospective Randomized Noninferiority Trial

    International Nuclear Information System (INIS)

    Purpose: To prospectively determine the effect of deodorant use on acute skin toxicity and quality of life during breast radiotherapy (RT). Methods and Materials: Before breast RT, 84 patients were randomly assigned to the deodorant group (n = 40) or the no-deodorant group (n = 44). The patients were stratified by axillary RT and previous chemotherapy. Toxicity evaluations were always performed by the principal investigator, who was unaware of the group assignment, at the end of RT and 2 weeks after completion using the Radiation Therapy Oncology Group acute skin toxicity criteria. Symptoms of acute skin toxicity (i.e., discomfort, pain, pruritus, sweating) and quality of life were self-evaluated. For each criterion, the point estimate of rate difference with the 95% one-sided upper confidence limit was computed. To claim noninferiority owing to deodorant use, the 95% one-sided upper confidence limit had to be lower than the noninferiority margin, fixed to 12.8%. Results: In the deodorant vs. no-deodorant groups, Grade 2 axillary radiodermatitis occurred in 23% vs. 30%, respectively, satisfying the statistical criteria for noninferiority (p = .019). Grade 2 breast radiodermatitis occurred in 30% vs. 34% of the deodorant vs. no-deodorant groups, respectively, also satisfying the statistical criteria for noninferiority (p = .049). Similar results were observed for the self-reported evaluations. The deodorant group reported less sweating (18% vs. 39%, p = .032). No Grade 3 or 4 radiodermatitis was observed. Conclusion: According to our noninferiority margin definition, the occurrence of skin toxicity and its related symptoms were statistically equivalent in both groups. No evidence was found to prohibit deodorant use (notwithstanding the use of an antiperspirant with aluminum) during RT for breast cancer.

    Hypertension is a major modifiable risk factor, and clinical trials have demonstrated that successful reduction of elevated blood pressure to target levels translates into decreased risk for the development of coronary artery disease, stroke, heart failure, and renal failure. The arterial system had previously been regarded as a passive conduit for the transportation of arterial blood to peripheral tissues. The physiologic role the arterial system was greatly expanded by the recognition of the central role of the endothelial function in a variety of physiologic processes. The role of arterial function and structure in cardiovascular physiology was expanded with the development of a variety of parameters that evaluate arterial stiffness. Markers of arterial stiffness have been correlated with cardiovascular outcomes, and have been classified as an emerging risk factor that provides prognostic information beyond standard stratification strategies involving hypertension, diabetes, obesity, dyslipidemia and smoking. Multiple epidemiologic studies have correlated markers of arterial stiffness such as pulse-wave velocity, augmentation index and pulse pressure with risk for the development of fatal and nonfatal cardiovascular events. Additionally, measurements of arterial stiffness had clarified the results of clinical trials that demonstrated differing impacts on clinical outcomes, despite similar reductions in blood pressure, as measured by brachial and sphygmomanometry.

    True upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Following computer-tomography angiographic (CT-a) imaging examination, true saccular aneurysm, originating from the left brachial artery was diagnosed in the 77-year-old female without history of trauma. The aneurysm was resected by surgical intervention, and primary repair of the brachial artery was performed by interposition of a part of great saphenous vein harvested from the left groin and creation of two end-to-end anastomoses between interposition graft and previously resected part of brachial artery. No complication was observed during the follow-up. Surgical intervention for upper extremity aneurysms should be initiated without delay. Factors combined with minimal morbidity associated with repair suggest that surgical repair should be performed routinely for true upper extremity arterial aneurysms. PMID:20865459

    The superficial temporal artery has been thought to be the main focus of pain during migraine attacks, but its diameter has never been measured directly. The use of a new, high-resolution ultrasound machine to measure arterial size in 25 migraine patients with unilateral head pain showed...... that the lumen was wider on the painful than on the non-painful side during a migraine attack. The diameters of both radial arteries and the temporal artery on the non-painful side were smaller during than between attacks. The generalised vasoconstriction was not shared by the temporal artery on the affected...... side, which suggests a local vasodilatory response. The findings suggest that cephalic arteries may play a role in migraine pathogenesis....

    Background: The diagnostic accuracy of FDG-PET/CT for the detection of axillary lymph node metastases in breast cancer patients acquired 60 min after FDG administration is reported to be only moderate, especially due to low sensitivity. Purpose: To test whether a delayed scan 90 min after FDG administration could enhance the diagnostic accuracy of FDG-PET/CT for the detection of axillary lymph node metastases. Material and Methods: Thirty-eight women suffering from primary breast cancer (mean age 52 years; range 25-78 years; standard deviation 14 years) underwent a pre-therapeutic dual-time-point FDG-PET/CT scan. The maximum standardized uptake value (SUVmax) of axillary lymph nodes was measured at two different time points (time point T1: 60 min after FDG injection, time point T2: 90 min after FDG injection). SUVmax of axillary lymph nodes at T1 and T2 were assessed for statistical significance using a paired Wilcoxon-Test (P < 0.05). At T1 a qualitative analysis of the FDG-PET/CT scan was performed to define physiologic and metastatic lymph nodes. At T2 an increase of the SUVmax of at least 3.75% over time was rated as indicating malignancy. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the accuracy of FDG-PET/CT for the detection of axillary lymph node metastases was calculated at time points T1 and T2. Statistically significant differences were determined using Fisher's exact test (P < 0.05). Histopathology served as the standard of reference. A compartment based analysis was done. Results: Axillary lymph nodes had a mean SUVmax of 1.6 (range 0.6-10.8; SD 1.9) at T1 and a mean SUVmax of 1.8 (range 0.5-17.9; SD 3.5) at T2. This difference was statistically significant (P = 0.047). The sensitivity, specificity, PPV, NPV, and accuracy of FDG-PET/CT for the detection of axillary lymph node metastases was 81%, 100%, 100%, 88%, and 92% at T1, and 88%, 50%, 56%, 85%, and 66% at T2, respectively.

    Various benign and malignant conditions could cause biliary obstruction. Compression of extrahepatic bile duct (EBD) by right hepatic artery was reported as a right hepatic artery syndrome but all cases were compressed EBD from stomach side. Our case compressed from dorsum was not yet reported, so it was thought to be a very rare case. We present here the first case of bile duct obstruction due to the compression of EBD from dorsum by right hepatic artery.

  15. Arterial mapping of lower limbs

    International Nuclear Information System (INIS)

    A bibliographic review is realized in the arterial mapping of lower limbs by ultrasonographic. The physical properties of the Doppler effect applied to diagnostic ultrasound are described. The anatomical characteristics of the general arterial system and specifically of the lower limbs arterial system are mentioned. Pathologies of the ischemic arterial disease of lower limbs are explained. The study characteristics of lower limbs arterial mapping are documented to determine its importance as appropriate method for the assessment of lower limb ischemia. An adequate arterial mapping of lower limbs is recognized in atherosclerotic ischemic disease as a reliable initial method alternative to arteriography. Arteriography is considered as reference pattern for therapeutic decision making in patients with critical ischemia of the lower limbs. Non-invasive methods to assess the arterial system of lower limbs has evidenced the advantages of the arterial mapping with Doppler, according to the consulted literature. The combination morphological and hemodynamic information has been possible and a map of the explored zone is made. The arterial mapping by ultrasonography has offered similar reliability to angiography

    Single coronary artery is a fairly rare entity which may nevertheless be found in 0.4 per cent of coronary arteriograms. The authors report 3 cases seen in 2 departments of cardiology. In each patient, despite the existence of definite cardiovascular risk factors, this distribution was a factor worsening coronary ischemia, leading to complete thrombosis in one case. Although most often a chance discovery, a review of the literature justifies the attribution to this anomaly of the onset of angina, infarction or even sudden death. PMID:1642437

    Full Text Available The diverse biological effects of hepatocyte growth factor/scatter factor (HGF/SF are mediated by c-Met which is preferentially expressed on epithelial cells. Met signaling has a role in normal cellular activities, and may be associated with development and progression of malignant processes. In this study presence of Met in the axillary drainage from patients who underwent conservative operations for breast cancer, and its prognostic significance was examined. Sixty-two consecutive patients with invasive ductal carcinoma of the breast which were suitable for breast-conserving treatment participated in the study. The output of the drain that had been placed in the axilla during the operation was collected, and the presence of Met and β-actin were assessed by reverse transcriptase-polymerase chain reaction (RT-PCR assays. The data were compared with the pathological features of the tumor and the axillary lymph nodes, and with the estrogen and progesterone receptors status.RT-PCR of the axillary lymphatic drainage was positive for Met in 46 (74.2% of the patients and positive assays were correlated with increase in tumor size and grade of capillary and lymphatic invasion, as well as with lymph node metastasis (P < 0.02, for all comparisons. All 24 patients with axillary lymph node metastases in comparison with those without lymph node (57.9% metastases had positive assays for Met. While all ten patients with tumor involvement in the margins of the resection had positive assays for Met in their lymphatic fluid, only 36 out of 52 patients (69.2% were positive for met assay. Finally, Met showed negative correlations with positive estrogen and progesterone receptor assays (P<0.02.From the results of this study it may concluded that Met can be detected in the axillary fluids of patients with breast cancer and its expression in the axillary drainage may be a potential prognostic factor. This finding might be useful in therapeutic considerations since a

    Carotid artery dissection is an important cause of ischemic stroke in all age groups, particularly in young patients. The purpose of this work was to assess whether there is an association between the presence of an internal carotid artery dissection (ICAD) and the arterial tortuosity. This study considered 124 patients (72 males and 52 females; median age 57 years) with CT/MR diagnosis of ICAD of the internal carotid artery were considered in this multi-centric retrospective study. The arterial tortuosity was evaluated and, when present, was categorized as elongation, kinking, or coiling. For each patient, both the right and left sides were considered for a total number of 248 arteries in order to have the same number of cases and controls. Fisher's exact test was applied to test the association between elongation, kinking, coiling, dissection, and the side affected by CAD. Fisher's exact test showed a statistically significant association between the ICAD and kinking (p = 0.0089) and coiling (p = 0.0251) whereas no statistically significant difference was found with arterial vessel elongation (p = 0.444). ICAD was more often seen on the left side compared to the right (p = 0.0001). These results were confirmed using both carotid arteries of the same patient as dependent parameter with p = 0.0012, 0.0129, and 0.3323 for kinking, coiling, and elongation, respectively. The presence of kinking and coiling is associated with ICAD. (orig.)

    Background— Bilateral internal thoracic arteries (BITA) have demonstrated superior patency and improved survival in patients undergoing coronary artery bypass grafting. However, the optimal configuration for BITA utilization and its effect on long-term outcome remains uncertain. Methods and Results— We randomly assigned 304 patients undergoing coronary artery bypass grafting using BITA to either in situ or Y grafting configurations. The primary end point was 3-year angiographic patency. Secondary end points included major adverse cardiac and cerebrovascular events (ie, death from any cause, stroke, myocardial infarction, or repeat revascularization) at 7 years. More coronary targets were able to be revascularized using internal thoracic arteries in patients randomized to Y grafting versus in situ group (3.2±0.8 versus 2.4±0.5 arteries/patient; PURL: http://www.clinicaltrials.gov.

    A new method has been developed to estimate total arterial compliance from measured input pressure and flow. In contrast to other methods, this method does not rely on fitting the elements of a lumped model to measured data. Instead, it relies on measured input impedance and peripheral resistance to calculate the relationship of arterial blood volume to input pressure. Generally, this transfer function is a complex function of frequency and is called the apparent arterial compliance. At very low frequencies, the confounding effect of pulse wave reflection disappears, and apparent compliance becomes total arterial compliance. This study reveals that frequency components of pressure and flow below heart rate are generally necessary to obtain a valid estimate of compliance. Thus, the ubiquitous practice of estimating total arterial compliance from a single cardiac cycle is suspect under most circumstances, since a single cardiac cycle does not contain these frequencies.

    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.)

    The term epigenetics is usually used to describe inheritable changes in gene function which do not involve changes in the DNA sequence. These typically include non-coding RNAs, DNA methylation and histone modifications. Smoking and older age are recognised risk factors for peripheral artery diseases, such as occlusive lower limb artery disease and abdominal aortic aneurysm, and have been implicated in promoting epigenetic changes. This brief review describes studies that have associated epigenetic factors with peripheral artery diseases and investigations which have examined the effect of epigenetic modifications on the outcome of peripheral artery diseases in mouse models. Investigations have largely focused on microRNAs and have identified a number of circulating microRNAs associated with human peripheral artery diseases. Upregulating or antagonising a number of microRNAs has also been reported to limit aortic aneurysm development and hind limb ischemia in mouse models. The importance of DNA methylation and histone modifications in peripheral artery disease has been relatively little studied. Whether circulating microRNAs can be used to assist identification of patients with peripheral artery diseases and be modified in order to improve the outcome of peripheral artery disease will require further investigation.

    Bioactive proanthocyanidins were isolated from the peel of Choerospondias axillaris fruit, which is a waste product of the food processing industry. Compositional analysis indicated that the proanthocyanidins had extension units mainly consisting of epicatechin gallate or epicatechin, and terminal units mainly consisting of catechin. Numerous polymeric forms of the molecules were detected, including monomers, dimers, and trimers. Certain fractions exhibited strong α-amylase or α-glucosidase inhibition in a dose-dependent manner. Furthermore, their inhibitory activities depended on their degree of polymerization and galloylation. For example, the most bioactive fraction had α-amylase and α-glucosidase inhibitory activities (IC50 values) of 541 and 3.1 μg mL(-1), respectively. This study demonstrates that proanthocyanidins from C. axillaris peels can inhibit carbohydrate digestive enzymes in vitro and may therefore serve as antidiabetic ingredients in functional or medical foods.

    The clinical value of ultrasonography of the axilla in detection of breast cancer recurrence is not known among patients who have a negative sentinel node biopsy and avoid axillary clearance. We studied a cohort of 205 such patients using ultrasonography one and three years after breast surgery. A recurrent tumour was found in the axilla in only two (0.5%) of the total of 383 ultrasound examinations performed during the study, and only one (0.3%) of the 369 examinations performed at the scheduled study visits revealed cancer. None of the ultrasound examinations was false positive, and no study participant was subjected to unnecessary surgery due to ultrasound monitoring. We conclude that the rate of breast cancer recurrence in the ipsilateral axilla is low following sparing of the axillary contents, and that monitoring of such patients with repeated ultrasound examinations is unlikely to be cost-effective.

    Migration of an implantable port catheter tip is one of the well-known complications of this procedure, but the etiology of this problem is not clear. We describe here a case of migration of the tip of a port catheter from the right atrium to the right axillary vein in a patient with severe cough. Coughing was suggested for this case as the cause of the catheter tip migration. We corrected the position of the catheter tip via transfemoral snaring

  12. Biomonitorization of cadmium, chromium, manganese, nickel and lead in whole blood, urine, axillary hair and saliva in an occupationally exposed population

    International Nuclear Information System (INIS)

    Heavy metal contamination from occupational origin is a cause for concern because of its potential accumulation in the environment and in living organisms leading to long term toxic effects. This study was aimed to assess Cd, Cr, Mn, Ni and Pb levels in whole blood, urine, axillary hair and saliva from 178 individuals with occupational exposure to heavy metals. Levels of metal compounds were determined by atomic absorption spectrometry. We collected information on occupation, lifestyle habits and food intake by questionnaire. Multiple linear regression analyses for metal ion concentration in whole blood, urine, axillary hair and saliva were adjusted for age, gender, smoking and alcohol consumption, lifetime workplace exposure, residence area and food habits. Overall, blood and urine median concentrations found for the five metals analyzed do not exceed biological exposure indexes, so that they are very similar to a non-occupationally exposed population. Toxicokinetic differences may account for the lack of correlations found for metal levels in hair and saliva with those in blood or urine. For those heavy metals showing higher median levels in blood with respect to hair (Cd, Mn and Pb) indicating lesser hair incorporation from blood, the lifetime working experience was inversely correlated with their hair levels. The longer the lifetime working experience in industrial environments, the higher the Mn and Ni concentration in saliva. Axillary hair and saliva may be used as additional and/or alternative samples to blood or urine for biomonitoring hair Mn, and saliva Ni in subjects with occupational exposure. - Research Highlights: → Metal levels in workers were similar to an occupationally non-exposed population. → Metal levels in blood and urine were below recommended reference values. → A lack of correlation was observed between metal levels in blood and saliva. → Toxicokinetic differences may account for the lack of correlations observed. → Axillary hair

  13. Is there a requirement for axillary lymph node dissection following identification of micro-metastasis or isolated tumour cells at sentinel node biopsy for breast cancer?

    LENUS (Irish Health Repository)

    Joyce, D P

    2012-02-29

    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.

    Recently, many centers have omitted routine axillary lymph node dissection (ALND) after metastatic sentinel node biopsy in breast cancer due to a growing body of literature. However, existing guidelines of adjuvant treatment planning are strongly based on axillary nodal stage. In this study, we aim to develop a novel international multicenter predictive tool to estimate a patient-specific risk of having four or more tumor-positive axillary lymph nodes (ALN) in patients with macrometastatic sentinel node(s) (SN). A series of 675 patients with macrometastatic SN and completion ALND from five European centers were analyzed by logistic regression analysis. A multivariate predictive model was created and validated internally by 367 additional patients and then externally by 760 additional patients from eight different centers. All statistical tests were two-sided. Prevalence of four or more tumor-positive ALN in each center's series (P = 0.010), number of metastatic SNs (P < 0.0001), number of negative SNs (P = 0.003), histological size of the primary tumor (P = 0.020), and extra-capsular extension of SN metastasis (P < 0.0001) were included in the predictive model. The model's area under the receiver operating characteristics curve was 0.766 in the internal validation and 0.774 in external validation. Our novel international multicenter-based predictive tool reliably estimates the risk of four or more axillary metastases after identifying macrometastatic SN(s) in breast cancer. Our tool performs well in internal and external validation, but needs to be further validated in each center before application to clinical use. PMID:23558360

  16. Fatal dissection of the pulmonary artery in pulmonary arterial hypertension

    2009-09-01

    Full Text Available A 41-yr-old patient with chronic stable idiopathic pulmonary arterial hypertension (PAH presented with sudden chest pain and unusual dyspnoea during physical exertion. The patient had been diagnosed with PAH at the age of 12 yrs and was in New York Heart Association functional class I/II. The patient was being treated with an anticoagulant regimen, low-dose diuretics and continuous intravenous epoprostenol therapy. A computed tomography scan showed ancient massive thrombi in dilated central pulmonary arteries, which were not haemodynamically significant (perfusion lung scans did not demonstrate segmental or larger defects, and extensive dissection of the right pulmonary artery starting from the intermediate branch. Due to the extensiveness of the dissection, the patient was immediately considered for heart–lung transplantation, but died 72 h after the onset of symptoms. Permission for post mortem examination was denied. Pulmonary artery dissection should be suspected in PAH patients presenting with chest pain and worsening dyspnoea. In the current case, the factors possibly associated with increased risk for dissection may include dilatation of the pulmonary artery, local inflammation favoured by in situ thrombosis, and acute increase of pulmonary pressure secondary to physical exertion. Extensive pulmonary artery dissection is a life-threatening complication of PAH, and urgent heart/lung transplantation might be the treatment of choice in eligible patients. In addition, better identification of the risk factors for pulmonary artery dissection may help in considering transplantation for selected patients at risk.

  17. Patent arterial duct

    Full Text Available Abstract Patent arterial duct (PAD is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes. Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of

    Purpose: In many centers, supraclavicular fossa radiotherapy (SCF RT) is not routinely offered to breast cancer patients with one to three positive lymph nodes. We aimed to identify a subgroup of these patients who are at high risk of supra or infraclavicular fossa relapse (SCFR) such that they can be offered SCFRT at the time of diagnosis to improve long term locoregional control. Methods and Materials: We performed a retrospective analysis of the pathological features of 1,065 cases of invasive breast cancer with one to three positive axillary lymph nodes. Patients underwent radical breast conserving surgery or mastectomy. A total of 45% of patients received adjuvant chest wall/breast RT. No patients received adjuvant SCFRT. The primary outcome was SCFR. Secondary outcomes were chest wall/breast recurrence, distant metastasis, all death, and breast-cancer specific death. Kaplan-Meier estimates were used to calculate actuarial event rates and survival functions compared using log-rank tests. Multivariate analyses (MVA) of factors associated with outcome were conducted using Cox proportional hazards models. Results: Median follow-up was 9.7 years. SCFR rate was 9.2%. Median time from primary diagnosis to SCFR was 3.4 years (range, 0.7-14.4 years). SCFR was associated with significantly lower 10-year survival (18% vs. 65%; p < 0.001). Higher grade and number of positive lymph nodes were the most significant predictors of SCFR on MVA (p < 0.001). 10 year SCFR rates were less than 1% in all patients with Grade 1 cancers compared with 30% in those having Grade 3 cancers with three positive lymph nodes. Additional factors associated with SCFR on univariate analysis but not on MVA included larger nodal deposits (p = 0.002) and proportion of positive nodes (p = 0.003). Conclusions: Breast cancer patients with one to three positive lymph nodes have a heterogenous risk of SCFR. Patients with two to three positive axillary nodes and/or high-grade disease may warrant

    Aspiration biopsy (FNAB) for the diagnosis of metastasis in the axillary lymph node (LN) of patients with breast cancer. A retrospective review of the data was performed on 327 breast cancer patients that underwent axillary US from Jun 2006 to July 2008. US guided FNAB was performed when a LN indicated suspicious findings. Results of FNAB were compared with those of subsequent surgery. Of the 327 patients, 111 showed suspicious findings on US and underwent FNAB. Among the 111 cases, 73 (66%) were positive for cancer, while 38 (34%) were negative results. A Total of 254 patients who had normal findings on US (n=216) and negative results on FNAB (n=38) underwent SNB, of which 56 (22%) were proven to have metastasis. Sensitivity and specificity of US were 61.9% and 81.8%, respectively, with a positive predictive value (PPV) of 65.8% and negative predictive value (NPV) of 79.2%. Sensitivity and specificity of US-guided FNAB were 86.9% and 100%, respectively, with a PPV of 100% and a NPV of 71.7%. US and US-guided FNAB performed for axillary staging are useful methods with a high specificity and positive predictive value in invasive breast cancer patients

  1. MicroRNA393 is involved in nitrogen-promoted rice tillering through regulation of auxin signal transduction in axillary buds

    Rice tillering has an important influence on grain yield, and is promoted by nitrogen (N) fertilizer. Several genes controlling rice tillering, which are regulated by poor N supply, have been identified. However, the molecular mechanism associated with the regulation of tillering based on N supply is poorly understood. Here, we report that rice microRNA393 (OsmiR393) is involved in N-mediated tillering by decreasing auxin signal sensitivity in axillary buds. Expression analysis showed that N fertilizer causes up-regulation of OsmiR393, but down-regulation of two target genes (OsAFB2 and OsTB1). In situ expression analysis showed that OsmiR393 is highly expressed in the lateral axillary meristem. OsmiR393 overexpression mimicked N-mediated tillering in wild type Zhonghua 11 (ZH11). Mutation of OsMIR393 in ZH11 repressed N-promoted tillering, which simulated the effects of limited N, and this could not be restored by supplying N fertilizer. Western blot analysis showed that OsIAA6 was accumulated in both OsmiR393-overexpressing lines and N-treated wild type rice, but was reduced in the OsMIR393 mutant. Therefore, we deduced that N-induced OsmiR393 accumulation reduces the expression of OsTIR1 and OsAFB2, which alleviates sensitivity to auxin in the axillary buds and stabilizes OsIAA6, thereby promoting rice tillering.

    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.

    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.

Several genes controlling rice tillering, which are regulated by poor N supply, have been identified. However, the molecular mechanism associated with the regulation of tillering based on N supply is poorly understood. Here, we report that rice microRNA393 (OsmiR393) is involved in N-mediated tillering by decreasing auxin signal sensitivity in axillary buds. Expression analysis showed that N fertilizer causes up-regulation of OsmiR393, but down-regulation of two target genes (OsAFB2 and OsTB1). In situ expression analysis showed that OsmiR393 is highly expressed in the lateral axillary meristem. OsmiR393 overexpression mimicked N-mediated tillering in wild type Zhonghua 11 (ZH11). Mutation of OsMIR393 in ZH11 repressed N-promoted tillering, which simulated the effects of limited N, and this could not be restored by supplying N fertilizer. Western blot analysis showed that OsIAA6 was accumulated in both OsmiR393-overexpressing lines and N-treated wild type rice, but was reduced in the OsMIR393 mutant. Therefore, we deduced that N-induced OsmiR393 accumulation reduces the expression of OsTIR1 and OsAFB2, which alleviates sensitivity to auxin in the axillary buds and stabilizes OsIAA6, thereby promoting rice tillering.

    In patients with pulmonary arterial hypertension (PAH), chest pain is most likely due to right ventricular demand ischemia. We report a patient with idiopathic PAH who developed severe angina due to extrinsic compression of the left main coronary artery (LMCA) from a dilated pulmonary artery trunk....... The diagnosis was verified by electrocardiogram after exercise, coronary angiography including intravascular ultrasound, and cardiac multidetector computed tomography (MDCT). The origin of the LMCA was high in the left coronary sinus, facilitating extrinsic compression. The patient was successfully treated...

    Spontaneous coronary artery dissection is an important etiology of nonatherosclerotic acute coronary syndrome, myocardial infarction, and sudden death. Innovations in the catheterization laboratory including optical coherence tomography and intravascular ultrasound have enhanced the ability to visualize intimal disruption and intramural hematoma associated with SCAD. Formerly considered "rare," these technological advances and heightened awareness suggest that SCAD is more prevalent than prior estimates. SCAD is associated with female sex, young age, extreme emotional stress, or extreme exertion, pregnancy, and fibromuscular dysplasia. The clinical characteristics and management strategies of SCAD patients are different than for atherosclerotic heart disease and deserve specific consideration. This review will highlight recent discoveries about SCAD as well as describe current efforts to elucidate remaining gaps in knowledge.

    Three kinds of carotid-basilar anastomosis have been found, they were named as persistent primitive trigeminal artery, persistent primitive acoustic (or otic) artery and persistent primitive hypoglossal artery, among them, the persistent primitive hypoglossal artery is by far the least common type of the internal carotid-basilar anastomosis which have been demonstrate in human postembryonic stages. Persistent primitive by hypoglossal artery is usually found incidentally. This vascular anomaly, however,have been reported to be associated with multiple congenital anomalies, such as unilateral or bilateral vertebral artery hypoplasia, absence of the posterior communicating artery, hypoplasia of the proximal portion of the posterior cerebral artery, aneurysm of the circle of Willis, the origin of both pericallosal arteries from a single anterior cerebral artery, retarded mental development dating from infancy, carotid-cavernous fistula formation etc. A case of persistent primitive hypoglossal artery in an young Korean male was reported with brief review of the literature.

  9. Total Arterial Revascularization with Internal Mammary Artery or Radial Artery Graft Configuration

    To investigate the clinical use of π graft in total arterial revascularization and its outcomes, a retrospective analysis of 23 patients out of 1000 patients undergoing total arterial coronary bypass surgery with a π graft between September 1994 and December 2004 was performed. In the selected patients for the management of triple vessel disease with middle diagonal/intermediate ramus disease such that a skip with the left internal mammary artery (LIMA) or radial artery (RA),the main stem of π graft, to the left anterior descending coronary artery (LAD) will not work and the right internal mammary artery (RIMA) or right gastroepiploic artery (RGEA) cannot pick up the diagonal/intermediate ramus, hence the LAD and diagonal/intermediate ramus were grafted with a mini Y graft using the distal segment of LIMA, RIMA, RA or RGEA, together with the bilateral internal mammary artery (BIMA) or LIMA-RA T graft to compose π graft. Twenty-three patients (18 males, 5 females) underwent the π graft procedure. There were no deaths or episodes of myocardial infarction, stroke, and deep sternal wound infection. One patient required reopening for controlling bleeding. Until the end of 2004, during a mean follow-up of 81.0 ±28.4 months, no angina needing re-intervention or operative therapy or coronary related death occurred. In conclusion, in patients with specific coronary artery anatomy/stenosis, the BIMA (sometimes LIMA with RA or RGEA) π graft can be successfully performed for total arterial revascularization with good midterm outcomes.

    Full Text Available Background: The proper knowledge of the course and ramification of blood vessels of lower limbs is very important for surgeons and interventional radiologist. Medial circumflex femoral artery usually originates from posteromedial aspect of the profunda femoris, but often originates from femoral artery itself. It has an important role in supplying blood to femoral neck and head, fatty tissue in acetabular fossa and used in flaps reconstructive surgery. Methods: 50 adult lowerlimbs were procured from embalmed cadavers of J.J.M. Medical College and S.S.I.M.S & R.C, Davangere, Karnataka, India for the study. Dissection of femoral triangle was carried out according to Cunningham’s manual. Site and mode of origin of the branches of femoral artery were studied, configuration of the femoral origins of medial and lateral circumflex femoral artery and their prevalence were studied. Results: Out of 50 extremities, Medial circumflex femoral artery took origin from profunda femoris in 41 specimens and from femoral artery in 9 specimens. Conclusion: The knowledge of normal origin and variation of medial circumflex femoral artery is very valuable in preventing iatrogenic injury to these vessels during surgical procedures of femoral triangle.

    Among coronary anomalies, Single Coronary Artery (SCA) is a rare anomaly in which one coronary artery stems from a single coronary ostium from the aortic sinuses, nourishing the entire heart. A very rare subtype of this anomaly is the anomalous origin of the Right Coronary Artery (RCA) from the distal Left Circumflex (LCx) artery.

    To find and describe the cerebellar arteries arising from the internal carotid artery, explain them embryologically, and evaluate their clinical implication. To determine the point in the internal carotid artery from which the cereballar artery arose anomalously, consecutive angiographic studies performed in the last three years were reviewed. The distribution of such anomalous cerebellar arteries, the point in the internal carotid artery from which the anomalous vessels originated, and associated findings were analyzed. Five anomalous origins of cerebellar arteries arising arising directly from the internal carotid artery were found in five patients. Three anterior inferior cerebellar arteries (AICA) and one common trunk of an AICA and a posterior inferior cerebellar artery (PICA) were found to originate from the internal carotid artery at a point close to the origin of the primitive trigeminal artery. A PICA arose from an artery presenting a course similar to the proatlantal intersegmental artery. Intracranial aneurysms in two patients, Moyamoya disease in one, and facial arteriovenous malformation in one. In our series, AICAs supplied from the arteries considered to be persistent trigeminal artery variants were the most common type. A correlation between type of anomalous cerebellar artery and type of carotid-vertebrobasilar anastomosis may exist. Cerebellar arteries originating anomalously from the internal carotid artery seem to occur as a result of the persistence of carotid-vertebrobasilar anastomoses associated with incomplete fusion of the longitudinal neural arteries. An understanding of these anomalous cerebellar arteries may help prevent accidents during therapeutic embolization and surgical treatment, as well as misinterpretation.

    Intra-arterial infusion of chemotherapy into the ophthalmic artery for treatment of retinoblastoma has been realized after catheterization of the internal carotid and temporary balloon occlusion beyond the orifice of the ophthalmic artery, or more recently after superselective canulation of the ophthalmic artery by a microcatheter. The superselective catheterization of the ophthalmic artery could be cumbersome because of the implantation of the ostium on the carotid siphon or because of the tortuosity of the carotid siphon. We report our experience of using a retrograde approach through the posterior communicating artery that allows a more direct angle of access to the origin of the ophthalmic artery. (orig.)

    Hayes, B

    2012-02-01

    BACKGROUND: Sentinel node (SN) biopsy is widely used to stage breast carcinoma and, when positive, typically leads to axillary clearance (AC). AIMS: This study assesses clinicopathologic features of grade 1 breast carcinoma SNs with the aim of identifying a group of patients, who are likely to have a negative AC and can, therefore, safely be spared further surgery. RESULTS: Two hundred and forty-seven patients with grade 1 invasive carcinoma were identified, of whom 29 had a positive SN. Four patients (13.8%) had a positive AC. Positive AC occurred in 3 of 6 (50%) patients whose SN showed extranodal extension (EE), but in only 1 of 23 (4.3%) patients without EE. All patients were staged as pN1(sn) following SN biopsy: only one, who had a 5.27 mm metastasis with EE, was pN2 following AC. CONCLUSIONS: Extranodal extension is a significant predictor of a positive AC in this group. In its absence, AC did not alter the post-SN biopsy pN stage.

    Full Text Available Post-mastectomy radiotherapy (PMRT in early breast cancer has long been a matter of debate among oncologists. The American Society of Clinical Oncology (ASCO and the American Society for Therapeutic Radiology and Oncology (ASTRO recommend the use of PMRT for patients, whose primary tumor is larger than 5 cm and/or patients who have four or more involved axillary lymph nodes (ALNs. Recently, few trials have been published showing the positive impact of PMRT on overall survival (OS even in patients having 1-3 positive ALNs with T1-T2 primary disease or early breast cancer (EBC. So, it has become a matter of controversy whether to radiate or not to radiate? We have made an extensive search in the internet in Pubmed and other sites of medical publication mentioning our topic of discussion and reviewed the relevant articles. We nearly got 3,220 articles. After reviewing the available publications in the internet, we blended the elixir with our experience and tried to find an answer of our question. In conclusion, PMRT significantly and substantially improved loco-regional control and overall survival in patients with 1-3 positive nodes as in patients with 4 or more positive nodes, and nearly the same number of patients is needed to treat to avoid a loco-regional recurrence and/or death in both groups. We should reconsider the current guidelines for the indication for PMRT.

    2014-01-01

    Full Text Available Background: Preoperative ultrasound (US and eventually US-guided fine-needle aspiration cytology (FNAC of suspicious axillary lymph nodes (ALN is a standard procedure in the work-up of suspicious breast lesions. Preoperative US FNAC may prevent sentinel node biopsy (SNB procedure in 24-30% of patients with early stage breast carcinoma. The aim of this study was to evaluate the institutional results of this preoperative diagnostic procedure. Materials and Methods: A total of 182 cases of preoperative FNAC of suspicious ALN where retrieved from the pathology files. The results were compared with the final histology and staging. False negative (FN FNAC cases were reviewed and possibly missed metastatic cases (2 were immunostained with the epithelial marker AE1/AE3. Results: There were no false positives, whereas 16 cases were FN. In all but one case the FN′s represented sampling error. Half of the 16 FN cases in this series were macrometastases. Discussion: About 83% of the preoperatively aspirated cases were N+, indicating that a radiologically suspicious ALN has a very high risk of being metastatic. Preoperative US guided FNAC from radiologically suspicious ALN is highly efficient in detecting metastases. Depending on national guidelines, a preoperative, positive ALN FNAC might help to stratify the patients as to SNB and/or ALN dissection.

    Full Text Available Background: Primary axillary hyperhidrosis (PAH is a common condition with a great impact on the patient′s quality of life (QOL. It is associated with serious social, emotional, and occupational distress. The aim of this study was to investigate the QOL in patients with PAH before and after treatment with fractionated microneedle radiofrequency (FMR. Materials and Methods: We evaluated 25 patients with severe PAH. Each patient had three sessions of FMR treatment using a novel applicator at 3-week intervals. The study was based on Dermatology Life Quality Index (DLQI Questionnaires. Patients were evaluated at baseline and 3 months after the last session. Results: Our patients included 32% males and 68% females. The mean ± standard deviation (SD age of subjects was 30.2 ± 6.27 years. The mean ± SD of the DLQI before and after treatment was 12.96 ± 5.93, and 4.29 ± 2.21, respectively. There was a statistically significant difference between the before and after intervention (P < 0.001. No major, permanent adverse effects were shown. Conclusion: Treatment with FMR can improve the DLQI of patients with PAH.

    Medicinal plants possess unlimited and untapped wealth of chemical compounds with high drug potential which make these plants useful as sources of biomedicines. The rising demand for herbal medicines in the organized manufacturing sector has ruthlessly exploited the wild growing plant population those have bulk use. So for high rate multiplication of different medicinal plants, it is necessary to standardize the protocol for high regeneration. The efficiency of any regeneration is primarily depends on factors like type of explants used, composition of the medium and type of genotype. Here, we have developed a regeneration protocol of Desmodium gangeticum (L.) DC (Salparni, Fam- Fabaceae) a medicinal plant through axillary bud multiplication. Nodal explants from Desmodium gangeticum plants were cultured on Murashige and Skoog's basal medium with Kn or BA at different concentrations. 0.5 mg L(-1) BA in the medium, showed shoot multiplication. Regenerated shoots measuring 3 cm or more were excised and planted on semi solid basal medium supplemented with varying concentrations of either IAA or IBA for induction of rooting. IBA treatment at 1.0 mg L(-1) was the best eliciting 100% rooting response. The in vitro propagation protocol standardized can be highly useful in raising quality planting materials of Desmodium gangeticum for commercial plantation programmes and germplasm conservation.

    Full Text Available Conservation of gadfly petrels, some of the most threatened seabirds, is frequently dependent on long-term research and management. We review 20 years of a program preventing the extinction of the Chatham petrel (Pterodroma axillaris, a New Zealand endemic once declining due to intense burrow competition from another native seabird. Breeding success in the early 1990s was unsustainably low (10–30%. Recovery measures started in 1992 when Chatham petrel burrows were converted and artificial entrances blockaded to exclude broad-billed prions (Pachyptila vittata. Pair and burrow fidelity were enhanced, though prions still posed a threat during Chatham petrel chick-rearing. Breeding success improved when prions were culled, however a less intensive and contentious solution was to introduce burrow flaps in 2001 which reduced interference from prospecting prions. Subsequently, breeding success increased to a mean 80% per annum. Finding burrows, primarily using radio-telemetry, increased those under management from eight in 1990 to 217 in 2010 when spotlight surveys indicated 72% of juvenile birds had fledged from managed burrows. Chick translocations to two other islands and increasing population size (from 200–400 birds in 1990 to an estimated 1400 birds by 2010 has improved the species IUCN status from Critically Endangered in 1990 to Endangered in 2013.

    Contralateral axillary lymph node metastases (CAMs) in breast cancer patients are uncommon. CAM can be found at the time of primary breast cancer diagnosis or following prior treatment of breast cancer as a recurrence. This distinction may have important implications for disease staging and treatment selection. We report the case of a premenopausal woman with synchronous CAM. Despite extensive multimodality treatment, a recurrence was found 27 months after primary surgery. We reviewed the literature on histopathological tumor characteristics associated with CAM, lymphatic drainage of the breast to other sites than the ipsilateral axilla, and outcome of cases with CAM. This case contradicts current conceptions that CAM only develops from tumors with poor histopathological features. Emerging evidence shows that altered lymphatics play a central role in development of synchronous CAM. It is precisely this etiology that supports the concept that synchronous CAM occurs by lymphatic spread and not by hematogenous spread. Although controversial, treatment of synchronous CAM (without evidence of distant metastases) should therefore be of curative intent. PMID:23607036

    Full Text Available Atherosclerosis is a chronic slow-developing condition affecting medium-size and large blood vessels. It is the principal underlying pathology of coronary heart disease and stroke. In some countries, coronary artery disease (CAD is the cause of nearly half (48% of the deaths and, loss of productivity life. Peripheral arterial disease (PAD is defined as atherosclerosis in peripheral arteries instead of coronary arteries. CAD and PAD have same risk factors and underlying pathophysiological processes. Therefore, patient with CAD should be considered for PAD. Ankle brachial index (ABI, duplex sonography, and some other non-invasive techniques are recommended for PAD diagnosis in patients with the history of CAD. Pharmacotherapy, endovascular interventions, and surgical management could be chosen according to the patient’s situation. Cardiologists and general practitioners should consider PAD in a patient with CAD or DM as a strong correlated disease.

    In bleeding of oesophageal varices with resistance to common treatment embolisation of the splenic artery causes depression of the portal hypertension by forty per cent. Thrombosis of the splenic or portal vein as in splenectomies are not to be expected. The splenic vein remains open for later spleno-renal anastomosis. By occlusion of the splenic artery we were successful in stopping oesophageal bleeding. In a patient with dominant hypersplenism in portal hypertension the severity of the syndrome decreased after embolisation of the splenic artery. Thrombocytes, leukocytes and gammaglobulin increased.

    Purpose: The purpose of this study was to identify the axillary lymph nodes on pretreatment diagnostic computed tomography (CT) of the chest to determine their position relative to the anatomic axillary borders as defined by the Radiation Therapy Oncology Group (RTOG) breast cancer atlas for radiation therapy planning. Methods and Materials: Pretreatment diagnostic CT chest scans available for 30 breast cancer patients with clinically involved lymph nodes were fused with simulation CT. Contouring of axillary levels I, II, and III according to the RTOG guidelines was performed. Measurements were made from the area of distal tumor to the anatomic borders in 6 dimensions for each level. Results: Of the 30 patients, 100%, 93%, and 37% had clinical involvement of levels I, II, and III, respectively. The mean number of lymph nodes dissected was 13.6. The mean size of the largest lymph node was 2.4 cm. Extracapsular extension was seen in 23% of patients. In 97% of patients, an aspect of the involved lymph node lay outside of the anatomic border of a level. In 80% and 83% of patients, tumor extension was seen outside the cranial (1.78 ± 1.0 cm; range, 0.28-3.58 cm) and anterior (1.27 ± 0.92 cm; range, 0.24-3.58 cm) borders of level I, respectively. In 80% of patients, tumor extension was seen outside the caudal border of level II (1.36 ± 1.0 cm, range, 0.27-3.86 cm), and 0% to 33% of patients had tumor extension outside the remaining borders of all levels. Conclusions: To cover 95% of lymph nodes at the cranial and anterior borders of level I, an additional clinical target volume margin of 3.78 cm and 3.11 cm, respectively, is necessary. The RTOG guidelines may be insufficient for coverage of axillary disease in patients with clinical nodal involvement who are undergoing neoadjuvant chemotherapy, incomplete axillary dissection, or treatment with intensity modulated radiation therapy.

    The prevalence of peripheral vascular disease in patients with coronary artery disease has been investigated in many different ways and depends on the diagnostic methods and the definition of the atherosclerotic manifestations in the different vascular beds. In this study we used the non-invasive methods digital volume pulse plethysmography and ankle and toe blood pressure measurements to identify arterial abnormalities in the lower limbs in 58 patients (49 males and 9 females; age 37-72 years) examined with coronary angiography. The prevalence of peripheral artery disease was 22%, in agreement with the results of most previous investigations. There was a tendency towards increasing prevalence of peripheral artery disease with more advanced coronary artery disease: 14% of the patients with no or minimal coronary atheromotous lesions, 18% of the patients with moderate coronary atheromotous lesions and 32% of the patients with marked coronary atheromotous disease. For this reason a non-invasive investigation of the peripheral arterial circulation should be included early in the clinical consideration of patients with chest pain or similar symptoms suggesting coronary heart disease. Toe pressure measurement appears to be the most appropriate technique being rather simple in management and also in evaluation of results. PMID:7658111

    Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

    Idiopathic arterial calcification in infancy is usually fatal with death in early life and diagnosis at post mortem. This report describes a unique, late presentation with hypertension and cardiac failure in a child aged 33 months, found to have widespread arterial calcification at radiological imaging. The calcium-phosphate axis was normal and there was no other demonstrable cause for calcification. Additionally, the histological features of arterial calcification at renal biopsy paralleled the findings in infants with this disorder. The late presentation in this case is unusual and has not been previously reported. Ultrasound and CT are sensitive for calcification, and the disease should be suspected in children presenting with cardiac or respiratory manifestations and features of arterial calcification, where no metabolic cause is established.

    Full Text Available Abstract Background The ergotamine tartrate associated with certain categories of drugs can lead to critical ischemia of the extremities. Discontinuation of taking ergotamine is usually sufficient for the total regression of ischemia, but in some cases it could be necessary thrombolytic and anticoagulant therapy to avoid amputation. Case report A woman of 62 years presented with a severe pain left forearm appeared 10 days ago, with a worsening trend. The same symptoms appeared after 5 days also in the right forearm. Physical examination showed the right arm slightly hypothermic, with radial reduced pulse in presence of reduced sensitivity. The left arm was frankly hypothermic, pulse less on radial and with an ulnar humeral reduced pulse, associated to a decreased sensitivity and motility. Clinical history shows a chronic headache for which the patient took a daily basis for years Cafergot suppository (equivalent to 3.2 mg of ergotamine. From about ten days had begun therapy with itraconazole for vaginal candidiasis. The Color-Doppler ultrasound shown arterial thrombosis of the upper limbs (humeral and radial bilateral, with minimal residual flow to the right and no signal on the humeral and radial left artery. Results Angiography revealed progressive reduction in size of the axillary artery and right humeral artery stenosis with right segmental occlusions and multiple hypertrophic collateral circulations at the elbow joint. At the level of the right forearm was recognizable only the radial artery, decreased in size. Does not recognize the ulnar, interosseous artery was thin. To the left showed progressive reduction in size of the distal subclavian and humeral artery, determined by multiple segmental steno-occlusion with collateral vessels serving only a thin hypotrophic interosseous artery. Arteriographic findings were compatible with systemic drug-induced disease. The immediate implementation of thrombolysis, continued for 26 hours, with

There is little information regarding arterial elasticity in heart transplant recipients. This study aimed to characterize small (SAE and large (LAE artery elasticity in heart transplant recipients in comparison with an asymptomatic population free of overt cardiovascular disease. A second goal was to identify demographic and clinical factors associated with arterial elasticity in this unique population.Methods: Arterial pulse waveform was registered noninvasively at the radial artery in 71 heart transplant recipients between 2008 and 2010. SAEs and LAEs were derived from diastolic pulse contour analysis. Comparisons were made to a healthy cohort of 1,808 participants selected from our prevention clinic database. Multiple regression analyses were performed to evaluate associations between risk factors and SAE and LAE within the heart transplant recipients.Results: LAE and SAE were significantly lower in heart transplant recipients than in the normal cohort (P <0.01 and P < 0.0001, respectively. Female sex and history of ischemic cardiomyopathy were significantly associated with reduced LAE and SAE. Older age and the presence of moderate cardiac allograft vasculopathy were also significantly associated with reduced SAE. Transplant duration was associated with increased SAE.Conclusion: Heart transplants are associated with peripheral endothelial dysfunction and arterial stiffness, as demonstrated by a significant reduction in SAE and LAE when compared with a

    Characteristic findings in patients with cirrhosis are vasodilatation with low overall systemic vascular resistance, high arterial compliance, increased cardiac output, secondary activation of counter-regulatory systems (renin-angiotensin-aldosterone system,sympathetic nervous system, release of vasopressin),and resistance to vasopressors. The vasodilatory state is mediated through adrenomedullin, calcitonin generelated peptide, nitric oxide, and other vasodilators,and is most pronounced in the splanchnic area.This constitutes an effective (although relative)counterbalance to increased arterial blood pressure.This review considers the alterations in systemic hemodynamics in patients with cirrhosis in relation to essential hypertension and arterial hypertension of the renal origin. Subjects with arterial hypertension (essential, secondary) may become normotensive during the development of cirrhosis, and arterial hypertension is rarely manifested in patients with cirrhosis, even in cases with renovascular disease and high circulating renin activity. There is much dispute as to the understanding of homoeostatic regulation in cirrhotic patients with manifest arterial hypertension. This most likely includes the combination of vasodilatation and vasoconstriction in parallel.

However, studies of arterial function in vegetarians are limited.Methods: This study investigated arterial function in vegetarianism by comparing 49 healthy postmenopausal vegetarians with 41 age-matched omnivores. The arterial function of the common carotid artery was assessed by carotid duplex, while the pulse dynamics method was used to measure brachial artery distensibility (BAD, compliance (BAC, and resistance (BAR. Fasting blood levels of glucose, lipids, lipoprotein (a, high-sensitivity C-reactive protein, homocysteine, and vitamin B12 were also measured.Results: Vegetarians had significantly lower serum cholesterol, high-density and low-density lipoprotein, and glucose compared with omnivores. They also had lower vitamin B12 but higher homocysteine levels. Serum levels of lipoprotein (a and high-sensitivity C-reactive protein were no different between the two groups. There were no significant differences in carotid beta stiffness index, BAC, and BAD between the two groups even after adjustment for associated covariates. However, BAR was significantly lower in vegetarians than in omnivores. Multiple linear regression analysis revealed that age and pulse pressure were two important determinants of carotid beta stiffness index and BAD. Vegetarianism is not associated with better arterial elasticity.Conclusion: Apparently healthy postmenopausal vegetarians are not significantly better in terms of carotid beta stiffness index, BAC, and BAD, but have significantly decreased BAR than

    Full Text Available Abstract Background 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 18F-fluorodeoxyglucose (18F-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 18F-FDG PET/CT for therapeutic indication of sentinel node biopsy (SNB and preoperative systemic chemotherapy (PSC. Methods One hundred eighty-three patients with primary operable breast cancer were recruited. All patients underwent 18F-FDG PET/CT and AUS followed by SNB and/or ALN dissection (ALND. Using 18F-FDG PET/CT, we studied both a visual assessment of 18F-FDG uptake and standardized uptake value (SUV for axillary staging. Results In a visual assessment of 18F-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 18F-FDG PET/CT and AUS to the axilla, the sensitivity, specificity, and accuracy were 64, 94, and 85%, respectively. If either 18F-FDG PET uptake or AUS was positive in allixa, the probability of axillary metastasis was high; 50% (6 of 12 in 18F-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 18F-FDG PET/CT, candidates of SNB were more appropriately selected. The axillary 18F-FDG uptake was correlated with the maximum size and nuclear grade of metastatic foci (p = 0.006 and p = 0.03. Conclusion The diagnostic accuracy of 18F-FDG PET/CT was shown to be nearly equal to ultrasound, and considering their

    Five cases of internal carotid-cerebellar artery anastomosis are presented. These anomalous vessels are identical to the so-called persistent trigeminal artery variant (PTAV). In our cases, two superior cerebellar arteries (SCAs), two anterior inferior cerebellar arteries (AICAs) and one posterior inferior cerebellar artery (PICA) arose from the precavernous segment of the internal carotid artery. We discuss the embryolgical and neuroradiological aspects of this anomaly.

  1. Role of axillary sentinel lymph node biopsy in patients with pure ductal carcinoma in situ of the breast

    Full Text Available Abstract Background Sentinel lymph node (SLN biopsy is an effective tool for axillary staging in patients with invasive breast cancer. This procedure has been recently proposed as part of the treatment for patients with ductal carcinoma in situ (DCIS, because cases of undetected invasive foci and nodal metastases occasionally occur. However, the indications for SLN biopsy in DCIS patients are controversial. The aim of the present study was therefore to assess the incidence of SLN metastases in a series of patients with a diagnosis of pure DCIS. Methods A retrospective evaluation was made of a series of 102 patients who underwent SLN biopsy, and had a final histologic diagnosis of pure DCIS. Patients with microinvasion were excluded from the analysis. The patients were operated on in five Institutions between 1999 and 2004. Subdermal or subareolar injection of 30–50 MBq of 99 m-Tc colloidal albumin was used for SLN identification. All sentinel nodes were evaluated with serial sectioning, haematoxylin and eosin staining, and immunohistochemical analysis for cytocheratin. Results Only one patient (0.98% was SLN positive. The primary tumour was a small micropapillary intermediate-grade DCIS and the SLN harboured a micrometastasis. At pathologic revision of the specimen, no detectable focus of microinvasion was found. Conclusion Our findings indicate that SLN metastases in pure DCIS are a very rare occurrence. SLN biopsy should not therefore be routinely performed in patients who undergo resection for DCIS. SLN mapping can be performed, as a second operation, in cases in which an invasive component is identified in the specimen. Only DCIS patients who require a mastectomy should have SLN biopsy performed at the time of breast operation, since in these cases subsequent node mapping is not feasible.

    Full Text Available Abstract Background The aim of this study was to develop a new data-mining model to predict axillary lymph node (AxLN metastasis in primary breast cancer. To achieve this, we used a decision tree-based prediction method—the alternating decision tree (ADTree. Methods Clinical datasets for primary breast cancer patients who underwent sentinel lymph node biopsy or AxLN dissection without prior treatment were collected from three institutes (institute A, n = 148; institute B, n = 143; institute C, n = 174 and were used for variable selection, model training and external validation, respectively. The models were evaluated using area under the receiver operating characteristics (ROC curve analysis to discriminate node-positive patients from node-negative patients. Results The ADTree model selected 15 of 24 clinicopathological variables in the variable selection dataset. The resulting area under the ROC curve values were 0.770 [95% confidence interval (CI, 0.689–0.850] for the model training dataset and 0.772 (95% CI: 0.689–0.856 for the validation dataset, demonstrating high accuracy and generalization ability of the model. The bootstrap value of the validation dataset was 0.768 (95% CI: 0.763–0.774. Conclusions Our prediction model showed high accuracy for predicting nodal metastasis in patients with breast cancer using commonly recorded clinical variables. Therefore, our model might help oncologists in the decision-making process for primary breast cancer patients before starting treatment.

    The aim of this study was to evaluate the frequency of false-negative (FN) sentinel node procedures in patients with breast cancer and the subsequent clinical outcome in such patients. A total of 325 breast cancer patients underwent sentinel lymph node biopsy at our institution between June 1998 and May 2004. A 2-day protocol was used to localise the sentinel node with the injection of{sup 99m}Tc-nanocolloid. There were two phases in the study: the learning phase (105 patients) and the application phase (220 patients). In the learning phase, a complete lymphadenectomy was always performed. In the application phase, sentinel nodes were studied intraoperatively and lymphadenectomy was performed when considered warranted by the pathological intraoperative results. The median follow-up duration in the 220 patients studied during the application phase was 21.2 months (range 4-45 months). In this phase a total of 427 sentinel nodes were obtained (range 1-5 per patient, median 1.99), with 66 positive sentinel nodes in 56 patients (26%). The lymphadenectomies performed were also positive in 25% of cases (14 patients). We observed a total of two false-negative sentinel lymph node results (3.45%). One of them was found during the surgical excision of non-sentinel nodes, and the other presented as an axillary recurrence 17 months postoperatively (1.72% clinical false-negative rate). The latter patient died 1 year after the first recurrence. After a median follow-up of 21.2 months we observed only one clinical recurrence among 220 patients. Our results indicate that adequate local control is achieved by application of the sentinel node protocol. (orig.)

    2006-05-01

    Full Text Available Abstract Background Aortic baroreceptors (BRs comprise a class of cranial afferents arising from major arteries closest to the heart whose axons form the aortic depressor nerve. BRs are mechanoreceptors that are largely devoted to cardiovascular autonomic reflexes. Such cranial afferents have either lightly myelinated (A-type or non-myelinated (C-type axons and share remarkable cellular similarities to spinal primary afferent neurons. Our goal was to test whether vanilloid receptor (TRPV1 agonists, capsaicin (CAP and resiniferatoxin (RTX, altered the pressure-discharge properties of peripheral aortic BRs. Results Periaxonal application of 1 μM CAP decreased the amplitude of the C-wave in the compound action potential conducting at 0.50 but completely inhibited discharge of an irregularly discharging BR (C-type. CAP at high concentrations (10–100 μM depressed BR sensitivity in regularly discharging BRs, an effect attributed to non-specific actions. RTX (≤ 10 μM did not affect the discharge properties of regularly discharging BRs (n = 7, p > 0.18. A CAP-sensitive BR had significantly lower discharge regularity expressed as the coefficient of variation than the CAP-resistant fibers (p Conclusion We conclude that functional TRPV1 channels are present in C-type but not A-type (A-δ myelinated aortic arch BRs. CAP has nonspecific inhibitory actions that are unlikely to be related to TRV1 binding since such effects were absent with the highly specific TRPV1 agonist RTX. Thus, CAP must be used with caution at very high concentrations.

    The purpose of this study is to present a case of RAO in a 13 year old girl with a preceding history of hyperextension of the neck at her hairdressers for a long duration and use of her mobile phone handset resting it against the side of her neck presumably exerting some pressure on carotids during the same time. Materials and methods of this study was reported as case report and review of literature. A 13 year-old girl presented with the left supero-nasal scotoma due to an inferior temporal branch retinal artery occlusion (BRAO). She underwent extensive investigations and no underlying cause was discovered. She gave a history of cervical extension over a long period of time while having the hair coloured twice in the preceding week. She also mentioned that she was using her mobile phone more or less continuously during both these occasions keeping it against her neck. Given the above history it is possible that the pressure on the ipsilateral carotid arteries or the prolong neck extension may have been responsible for the formation of a platelet embolus resulting in the BRAO. In conclusion, although cerebro-vascular accidents due to 'beauty parlor stroke syndrome' (JAMA 269:2085-2086, 1993) have been reported previously it has not been reported in children to our knowledge. On the other hand, 'beauty parlor stroke syndrome' occurs due to a dissection of the vertebral arteries or due to mechanical compression of the vertebral arteries during the prolonged hyperextension of the neck. The central retinal artery originates from the internal carotid circulation and it is highly unlikely for an embolus to enter the retinal circulation from the vertebral arteries. Therefore, the authors favour the possibility that the compulsive use of a mobile phone exerting pressure on the carotid arteries for a long time may have led to the formation of an embolus and subsequent RAO in this case.

     Vascular anatomy of the liver is varied, and the"standard"anatomy is seen in 55%-80%of cases. It is very important that extrahepatic arteries are identiifed precisely at the time of graft procurement to avoid injuries that might compromise the liver function. In the present case the liver donor had the vascular anatomy of Michels type Ⅶ, e.g. a hepatic artery originating from the celiac trunk and going to the left lobe, an accessory left hepatic artery coming from the left gastric artery, and a replaced right hepatic artery coming from the superior mesenteric artery. This pattern of vascular supply is uncommon, representing less than 5%of cases. The replaced hepatic artery was reconstructed in the back-table with polypropylene suture 7.0 by connecting it to the stump of the splenic artery, and the celiac trunk of the graft was anastomosed to the recipient common hepatic artery.

  9. Expression of LRP and MDR1 in locally advanced breast cancer predicts axillary node invasion at the time of rescue mastectomy after induction chemotherapy

    International Nuclear Information System (INIS)

    Axillary node status after induction chemotherapy for locally advanced breast cancer has been shown on multivariate analysis to be an independent predictor of relapse. However, it has been postulated that responders to induction chemotherapy with a clinically negative axilla could be spared the burden of lymphadenectomy, because most of them will not show histological nodal invasion. P-glycoprotein expression in the rescue mastectomy specimen has finally been identified as a significant predictor of patient survival. We studied the expression of the genes encoding multidrug resistance associated protein (MDR1) and lung cancer associated resistance protein (LRP) in formalin-fixed, paraffin-embedded tumor samples from 52 patients treated for locally advanced breast cancer by means of induction chemotherapy followed by rescue mastectomy. P-glycoprotein expression was assessed by means of immunohistochemistry before treatment in 23 cases, and by means of reverse-transcriptase-mediated polymerase chain reaction (RT-PCR) after treatment in 46 (6 failed). LRP expression was detected by means of immunohistochemistry, with the LRP-56 monoclonal antibody, in 31 cases before treatment. Immunohistochemistry for detecting the expression of c-erb-B2, p53, Ki67, estrogen receptor and progesterone receptor are routinely performed in our laboratory in every case, and the results obtained were included in the study. All patients had received between two and six cycles of standard 5-fluorouracil, doxorubicin and cyclophosphamide (FAC) chemotherapy, with two exceptions [one patient received four cycles of a docetaxel-adriamycin combination, and the other four cycles of standard cyclophosphamide-methotrexate-5-fluorouracil (CMF) polychemotherapy]. Response was assessed in accordance with the Response Evaluation Criteria In Solid Tumors (RECIST). By these, 2 patients achieved a complete clinical response, 37 a partial response, and the remaining 13 showed stable disease. This makes a

  10. Factors associated with regional nodal failure in patients with early stage breast cancer with 0-3 positive axillary nodes following tangential irradiation alone

    International Nuclear Information System (INIS)

    Purpose: Recent randomized trials have suggested that improved local-regional control after radiation therapy significantly increases survival for breast cancer patients with positive axillary nodes treated with adjuvant systemic therapy . It has been our policy to use a third radiation field only in patients with 4 or more positive nodes. The purpose of this study was to assess whether there are any clinical or pathologic factors associated with an increased risk of regional nodal failure (RNF) in patients with 0-3 positive nodes treated with tangential radiotherapy (RT) alone with or without systemic therapy. Methods and Materials: We retrospectively analyzed the incidence of RNF for 691 patients with clinical Stage I or II invasive breast cancer treated with complete gross excision of the primary tumor and tangential RT alone between 1978-87; 12% also received systemic therapy. All had 0-3 positive nodes on axillary dissection that had histologic examination of ≥ 6 nodes, and all had potential 8-year follow-up. The median number of axillary nodes removed was 11 (range 6-36). RNF was defined as any recurrence in ipsilateral axillary, internal mammary, supraclavicular, or infraclavicular nodes in the absence of recurrence in the breast, with or without simultaneous distant metastasis. Crude rates for first sites of failure within the first 8 years after treatment were calculated. A polychotomous logistic regression was used to identify factors prognostic for RNF and other sites of first failure. Results: Within 8 years, RNF was the first site of failure for 27 patients for a crude 8-year rate of 3.9%. Isolated axillary failure occurred in 8 patients (1.2%). Isolated supraclavicular and/or infraclavicular failure occurred in 5 (1.3%) and 3 (0.4%) patients, respectively. Isolated internal mammary node failure occurred in 2 patients (0.3%). A polychotomous logistic regression model of first site of failure (local failure, regional nodal, distant/opposite breast

    Objective To test the clinical value of using Tc-99m MIBI scintimammography (Tc-99m MIBI SMM) to differentiate nodular lesions in breasts and detect axillary lymph node metastases of breast cancer. Methods The subjects consisted of sixty female patients exhibiting unilateral palpable breast mass. The early and delay static acquisitions were undertaken in all subjects at 10 and 90 min after injection with Tc-99m MIBI. The acquisition included three positions: anterior supine, left lateral prone and right lateral prone. A special device for SMM which was developed by our laboratory was used. The ratio of [(T-B)/(NT-B)] was calculated as radioactivity of mass to that of opposite corresponding tissue, and [(T-B)/(NT-B)]≥1.21 was used as the cut-off for semi-quantitative discrimination of malignancy from benignity in semi-quantitative analysis. The final diagnosis was obtained from histology examination in all subjects. Results Using Tc-99m MIBI SMM to differentiate between nodular lesions in breasts, the diagnostic sensitivity and specificity were 92.9% and 90.6% respectively, the positive predictive value 89.7%, the negative predictive value 93.5%, and the accuracy 91.7%. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy obtained with Tc-99m MIBI SMM for detecting axillary lymph node metastases were 83.3%, 86.1%, 80%, 88.6% and 85% respectively. Conclusions It is suggested that Tc-99m MIBI SMM may be not only valuable in differentiating malignant lesions from benign nodular masses of breast, but also helpful in detecting axillary lymph node metastases of breast cancer.

    The aim of this study was to assess the accuracy of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT to visualize lymph node metastases before the start of neoadjuvant chemotherapy and to determine how often the visualization is sufficiently prominent to allow monitoring of the axillary response. Thirty-eight patients with invasive breast cancer of >3 cm and/or lymph node metastasis underwent FDG PET/CT before neoadjuvant chemotherapy. The results of the FDG PET/CT were compared with those from ultrasonography with fine-needle aspiration (FNA) cytology or sentinel node biopsy. Patients suitable for response monitoring of the axilla were defined as having either a maximum standardized uptake value (SUV{sub max}){>=}2.5 or a tumour to background ratio {>=}5 in the most intense lymph node. The sensitivity and specificity of FDG PET/CT in detecting axillary involvement were 97 and 100%, respectively. No difference existed between the SUV{sub max} of the primary tumour and that from the related most intense lymph node metastasis. Moreover, the mean tumour to background ratio was 90% higher in the lymph nodes compared to the primary tumour (p=0.006). Ninety-three per cent of the patients had sufficient uptake in the lymph nodes to qualify for subsequent response monitoring of the axilla. A considerable distinction in metabolic activity was observed between the different subtypes of breast cancer. The mean SUV{sub max} in lymph node metastases of oestrogen receptor (ER)-positive, triple-negative and human epidermal growth factor receptor 2 (HER2)-positive tumours was 6.6, 11.6 and 6.6, respectively. The high accuracy in visualizing lymph node metastases and the sufficiently high SUV{sub max} and tumour to background ratio at baseline suggest that it is feasible to monitor the axillary response with FDG PET/CT, especially in triple-negative tumours.

    Full Text Available Background : Gabapentin has been recently found to be useful for reducing acute postoperative pain when administered preoperatively. Although various dose regimens have been tried in different surgical settings, the minimum effective dose is not established. Aims : We aimed to evaluate the analgesic efficacy of single low dose gabapentin in patients undergoing total mastectomy and axillary dissection. Settings and Design : Prospective randomized placebo-controlled double-blind trial in a tertiary care teaching hospital. Materials and Methods : Fifty women scheduled for total mastectomy and axillary dissection were randomized to receive either gabapentin 600 mg or placebo orally 1 h preoperatively. The intraoperative and postoperative management was standardized. Postoperative pain was assessed at rest and on movement for 12 h using the numerical rating scale (NRS. Morphine was administered if NRS exceeded 30. Primary outcome measure was total morphine consumption. Statistical Analysis : The morphine consumption was compared using independent t test while pain and sedation scores were analyzed using Mann-Whitney U test. Results : Forty-six patients completed the trial. The postoperative morphine consumption was significantly less (5.8 ± 4.2 vs. 11.0 ± 3.4 mg; P 〈 0.001 and the median [IQR] time to first analgesic was significantly longer (90 [37.5-120] vs. 0 [0-90] min; P 〈 0.001 in the gabapentin group than in the placebo group. The incidence of side effects was similar in the two groups. Conclusions : A single low dose of 600 mg gabapentin administered 1 h prior to surgery produced effective and significant postoperative analgesia after total mastectomy and axillary dissection without significant side effects.

    2009-01-01

    Full Text Available Basilar artery thrombosis has high morbidity and mortality. Though intra-arterial thrombolytics have proven efficacy in the treatment of acute basilar artery occlusion, the elevation of procoagulant factors in the blood after intra-arterial thrombolysis could result in subsequent thrombus formation and clinical deterioration. Glycoprotein IIb/IIIa inhibitors have been shown to reduce this elevation in procoagulants. We present a pilot study of three cases of acute basilar artery occlusion treated with a combination of intra-arterial thrombolytics and Gp IIb/IIIa inhibitor with remarkable clinical recovery seen in all the patients.

    Common bile duct cancer invading right hepatic artery is sometimes diagnosed intraoperatively. Excision and safe reconstruction of the artery with suitable graft is essential. Arterial reconstruction with autologous saphenous vein graft is the preferred method practiced routinely. However the right hepatic artery reconstruction has also been carried out with several other vessels like gastroduodenal artery, right gastroepiploic artery or the splenic artery. We report a case of 63-year-old man presenting with history of progressive jaundice, pruritus and impaired appetite. Following various imaging modalities including computed tomography, endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography, intraductal ultrasound extrahepatic bile duct cancer was diagnosed; however, none of those detected vessel invasion. Intraoperatively, right hepatic artery invasion was revealed. Right hepatic artery was resected and reconstructed with a graft harvested from the first jejunal artery (JA). Postoperative outcome was satisfactory with a long-term graft patency. First JA can be a reliable graft option for right hepatic artery reconstruction.

    Once considered uncommon, spontaneous dissection of the carotid artery is an increasingly recognized cause of stroke, headache, cranial nerve palsy, or ophthalmologic events, especially in young adults. Even in the presence of existing signs and symptoms, the diagnosis can be missed by experienced physicians of all specialties. We report a case of spontaneous internal carotid artery dissection in a 38-year-old woman with a cortical stroke and visual disturbances as initial symptoms. The diagnosis was confirmed by magnetic resonance imaging/angiography and by angiography. Prompt anticoagulation was instituted, and the patient had complete resolution of symptoms. Cervicocephalic arterial dissection should be included in the differential diagnosis of the causes of cerebrovascular events.

    A report is made of 3 observations of vascular constrictions in the knee hollow of three young adults: two constrictions of the popliteal artery, one by abnormal insertion of a tendon of the gastrocnemius muscle and of the arterial passage, the other by a fibrous band surrounding the artery. In one observation, the disorder was revealed by acute ischemia of one limb. The third observation was of a sural phlebitis with secondary repetition at the constriction of the popliteal vein by Soleaire's arcade. In all cases examination using the Doppler effect, in baseline and especially dynamic position, gives a diagnosis and allows postoperative monitoring. Bilateral arteriography, both static and dynamic, allows a precise diagnosis to be given and reveals the extent of vascular lesions, which conditions the operative technique. Treatment is always surgical, with exploration of the contralateral side if a constriction is suspected, even if it is asymptomatic. PMID:3707018

    Full Text Available Introduction: Persistent median artery originates from the anterior interosseous artery in proximal one-third of the forearm and accompanies median nerve. Median artery may regress in the forearm or enter palm through the carpal tunnel deep to flexor retinaculum of wrist and supply palm by anastomosing with the superficial palmar arch. Objective: In present study the objective was to study presence of persistent median artery accompanying median nerve and its termination Materials and Methods: The study included 50 human cadaver upper limb specimens at the Department of Anatomy, Mysore Medical College & Research Institute, Mysore during 2011-13. These specimens fixed in 10% formalin were finely dissected and persistent median artery was traced from origin to termination. Results: Out of 50 human cadaver specimens, persistent median artery was present in 4 specimens (8%. All the 4 median arteries originated from anterior interosseous artery and were of palmar type which reached palm. Out of 4 median arteries, 3 median arteries (6% took part in completion of superficial palmar arch, supplying the distal aspect of palm and 1 median artery (2% directly supplied radial two and half fingers without forming arch. Conclusion: Knowledge of unusual variations helps in proper treatment of disorders of the median nerve. Presence of persistent median artery usually will be asymptomatic but may cause symptoms of carpal tunnel syndrome or pronator teres syndrome when subjected to compression. Rarely this artery can be taken for reconstruction

    Purpose: to examine the prognosis of breast cancer patients (T1-3, one to three positive axillary lymph nodes) and locoregional failure rate after breast-conserving therapy/modified radical mastectomy and adequate axillary dissection following tangential radiotherapy without irradiation of the regional lymph nodes. Patients and methods: from 1994 to 2002, the medical records of 183 breast cancer patients (T1-3, one to three involved axillary lymph nodes) were examined in order to identify those experiencing regional nodal recurrence, with or without local recurrence. The median age of the patient population was 58 years (range, 28-86 years). All patients underwent surgical treatment, either breast-conserving therapy (n = 146) or modified radical mastectomy (n = 37). The median number of lymph nodes removed was twelve (range, seven to 26 nodes). Irradiation was given to the breast through tangential fields. Chemotherapy was administered to 101 patients (55%), hormonal therapy to 124 (60%), and combined systemic treatment to 47 (26%). Results: the median observation time was 44.4 months (range, 11-102 months). Of the 14 patients (7.7%) with a relapse, six (3.3%) had a local recurrence, five (2.8%) a regional relapse, and three (1.6%) a simultaneous recurrence. Nine out of 14 patients with locoregional relapse developed distant failure subsequently and seven of them (78%) died of the disease. Conclusion: regional recurrence is uncommon among patients with one to three positive axillary lymph nodes treated with surgery, adequate axillary dissection, and tangential field irradiation only. The authors conclude that regional nodal irradiation should not routinely be given following adequate axillary dissection when only one to three lymph nodes are positive. (orig.)

    Full Text Available Vertebral artery arises from the upper surface of the first part of subclavian artery on both sides. The morphological variations of the vertebral artery are of immense importance in surgery, angiography and all non-invasive procedures. During the routine dissection of a male cadaver aged about 65 years, we observed a variation in the branching of arch of aorta. The arch of aorta gave off four branches-brachiocephalic trunk, left common carotid artery (CCA, left vertebral artery (LVA and left subclavian artery. LVA was arising between left CCA and left subclavian artery.The knowledge of variations in the vertebral artery is of great clinical interest to the neurosurgeon and radiologist for diagnostic investigation and surgical procedures of the neck.

    The trigeminal artery is the largest of the fetal carotid-basilar anastomotic arteries, and it persists for the longest embryonic period. The artery usually involutes after the development of the posterior communicating artery. The exact causes of persistence of this primitive vessel into adulthood are not completely clear. Angiographic and anatomical descriptions of the various persistent trigeminal artery (PTA) configurations and their relation to the remainder of the cerebrovascular tree and the other surrounding structures have been reported. Persistent trigeminal artery can be associated with many other vascular anomalies and disorders including aneurysms, arteriovenous malformations and carotid-cavernous fistulae. A thorough understanding of the anatomical and angiographic features of this persistent embryonic arterial channel is of utmost importance when making therapeutic decisions and embarking on surgical or endovascular intervention for any pertinent pathological condition. We review the embryology, angiographic features, microsurgical anatomy and associated vascular anomalies and disorders of the persistent trigeminal artery. PMID:22843453

    Background— Bilateral internal thoracic arteries (BITA) have demonstrated superior patency and improved survival in patients undergoing coronary artery bypass grafting. However, the optimal configuration for BITA utilization and its effect on long-term outcome remains uncertain. Methods and Results— We randomly assigned 304 patients undergoing coronary artery bypass grafting using BITA to either in situ or Y grafting configurations. The primary end point was 3-year angiographic patency. Secondary end points included major adverse cardiac and cerebrovascular events (ie, death from any cause, stroke, myocardial infarction, or repeat revascularization) at 7 years. More coronary targets were able to be revascularized using internal thoracic arteries in patients randomized to Y grafting versus in situ group (3.2±0.8 versus 2.4±0.5 arteries/patient; P<0.01). The primary end point did not show significant differences in graft patency between groups. Secondary end points occurred more frequently in the in situ group (P=0.03), with 7-year rates of 34±10% in the in situ and 25±12% in the Y grafting groups, driven largely by a higher incidence of repeat revascularization in the in situ group (14±4.5% versus 7.4±3.2% at 7 years; P=0.009). There were no significant differences in hospital mortality or morbidity or in late survival, myocardial infarction, or stroke between groups. Conclusions— Three-year systematic angiographic follow-up revealed no significant difference in graft patency between the 2 BITA configurations. However, compared with in situ configuration, the use of BITA in a Y grafting configuration results in lower rates of major adverse cardiovascular and cerebrovascular events at 7 years.

    After coronary artery bypass, some patients have diaphragmatic elevation, usually on the left side. To test our hypothesis that this phenomenon is due to phrenic nerve injury resulting from either 1) dissection of the proximal portion of the left internal mammary artery or 2) topical cooling of the heart with icy slush, we performed the following 2-part study. First, we reviewed our hospital records of 99 coronary artery bypass patients, 55 of whom had received left internal mammary artery gr...

    Full Text Available The purpose of this study was to assess the usefulness of HER2 levels in ultrasonographically guided fine-needle aspiration biopsy (US-FNA aspirates of axillary lymph nodes (ALNs in the determination of lymph node metastasis or the characterization of primary breast cancer, and to correlate the HER2 levels in US-FNA aspirates (FNA-HER2s of metastatic ALNs with the HER2 statuses of corresponding primary breast cancers. An institutional review board approved the study. Between January and October 2010, 164 patients with 167 ALNs examined by US-FNA were included. FNA-HER2s of ALNs were measured by chemiluminescence immunoassay, and they were correlated with cytologic/final diagnoses. Receiver operating characteristics (ROC curve analysis was performed to evaluate the diagnostic ability to differentiate benign and metastatic ALNs. Additionally, FNA-HER2s of metastatic ALNs were correlated with HER2 status and other clinicopathologic variables of the primary breast cancers. Among the 167 ALNs, 138 were metastatic and 29 were benign. The mean FNA-HER2 (6.3 ng/ml of metastatic ALNs was higher than that of benign ALNs. All 29 benign ALNs showed no measurable value of FNA-HER2 (0.0 ng/ml. The area under the ROC curves of FNA-HER2 of ALNs was 0.679 for the diagnosis of ALN metastasis. The FNA-HER2 statuses of 108 metastatic ALNs (79.4% were concordant with the HER2 statuses of the corresponding primary breast cancers. In a subgroup analysis of HER2-positive cancers with ALN metastasis, distant metastasis was significantly associated with FNA-HER2-negativity of metastatic ALNs (P = 0.04. Although FNA-HER2 of ALNs did not improve the diagnostic performance of FNA cytology in preoperative diagnosis of ALN metastasis of overall patients, FNA-HER2-positive metastatic ALNs were significantly associated with HER2-positivity of primary breast cancers. Additionally, FNA-HER2 analysis of ALN may help to develop more personalized treatment protocol for breast

    Thamnocalamus falconeri, Hook.f. ex Munro., an important bamboo species belonging to the family Po-aceae, locally known as Ringal, occurs in the hills of Ut-tarakhand, India. This species has been traditionally exploited by local communities to support their livelihoods. Increasing needs of the hill villages impose unsustainable pressure on natural stands of Ringal in the Uttarakhand hills and forests have been degraded. The long history of excessive cutting of Ringal from natural forests and the lack of replanting threaten villager livelihoods. Replanting is required to conserve the species. We propose a protocol for generation of planting material through axillary bud proliferation for multiplication and conservation of this species. We collected offsets/rhizomes from a natural stand of T. falconeri in the Chopta Mandal areas (Chamoli dis-trict, India). These were planted at sites of varied elevation and fresh single nodal segments were collected from them as explants. Different sterilization treatments were assessed to combat contamination. Among these, treatment of 0.1%HgCl2 followed by 5% NaOCl, proved best. Among two cytokinin treatments, viz. BAP and Kinetin, singly or in combination, BAP alone (5 mg L-1) proved superior and resulted in 100% bud break. BAP-supplemented MS media yielded maximum vigorous shoot formation (90%) and maximum number of shoots (8.9). Subculturing of shoots on the same medium with similar BAP treatment (5 mg L-1 BAP) enabled continuous production of healthy shoots at similar frequency. Maximum rooting (100%) was recorded on half-strength MS medium supplemented with 5 mg L-1 IBA. Micropropagated plants were hard-ened and acclimatized in soil mixture (2:1:1) and then transplanted to field sites (Magra, Uttarakhand, 1,834 m). Eight to ten months after field transplantation we recorded 100% survival of transplanted material. This microprop-agation protocol could be used successfully for raising a stock of genetically homogenous plant

    The present report describes a rare case in which the left gastric artery arises directly from the abdominal aorta and the right hepatic artery from the superior mesenteric artery, as observed during the dissection of a female cadaver. The left gastric artery usually rises as one of the three branches of the celiac trunk, which was originally described by Haller in 1756, whereas the right hepatic artery usually originates from the proper hepatic artery. The knowledge of the typical anatomy of the abdominal arteries, and their variations, is especially important due to the numerous interventions performed in the abdominal area.

    Although phytohormones such as indole-3-acetic acid (IAA), cytokinin (CK) and strigolactone are important modulators of plant architecture, it remains unclear whether reactive oxygen species are involved in the regulation of phytohormone-dependent axillary bud outgrowth in plants. We used diverse techniques, including transcriptional suppression, HPLC-MS, biochemical methodologies and gene transcript analysis to investigate the signaling pathway for apoplastic hydrogen peroxide (H2 O2 )-induced axillary bud outgrowth. Silencing of tomato RESPIRATORY BURST OXIDASE HOMOLOG 1 (RBOH1) and WHITEFLY INDUCED 1 (WFI1), two important genes involved in H2 O2 production in the apoplast, enhanced bud outgrowth, decreased transcript of FZY - a rate-limiting gene in IAA biosynthesis and IAA accumulation in the apex - and increased the transcript of IPT2 involved in CK biosynthesis and CK accumulation in the stem node. These effects were fully abolished by the application of exogenous H2 O2 . Both decapitation and the silencing of FZY promoted bud outgrowth, and downregulated and upregulated the transcripts for IAA3 and IAA15, and IPT2, respectively. However, these effects were not blocked by treatment with exogenous H2 O2 but by napthaleneacetic acid (NAA) treatment. These results suggest that RBOHs-dependent apoplastic H2 O2 promotes IAA biosynthesis in the apex, which, in turn, inhibits CK biosynthesis and subsequent bud outgrowth in tomato plants.

    Removal of terminal buds (topping) and control of the formation of axillary shoots (suckers) are common agronomic practices that significantly impact the yield and quality of various crop plants. Application of chemicals (suckercides) to plants following topping is an effective method for sucker control. However, our current knowledge of the influence of topping, and subsequent suckercide applications, to gene expression is limited. We analyzed the differential gene expression using RNA-sequencing in tobacco (Nicotiana tabacum) that are topped, or treated after topping by two different suckercides, the contact-localized-systemic, Flupro(®) (FP), and contact, Off-Shoot-T(®). Among the differentially expressed genes (DEGs), 179 were identified as common to all three conditions. DEGs, largely related to wounding, phytohormone metabolism and secondary metabolite biosynthesis, exhibited significant upregulation following topping, and downregulation after suckercide treatments. DEGs related to photosynthetic processes were repressed following topping and suckercide treatments. Moreover, topping and FP-treatment affect the expression of auxin and cytokinin signaling pathway genes that are possibly involved in axillary shoot formation. Our results provide insights into the global change of plant gene expression in response to topping and suckercide treatments. The regulatory elements of topping-inducible genes are potentially useful for the development of a chemical-free sucker control system. PMID:26670135

    In the recent years several studies have shown that about 30% of cases with axillary node-nagative breast cancer suffer relapse of the disease. Our attempt was made to evaluate the most significant prognostic factors to predict this high risk group which may be benefited from adjuvant treatment. For this purpose, we selected 9 patients out of 80 cases of node-negative breast cancer who had been followed up at least for 5 years and had the recurrence of the disease. For comparison, 16 patients from the same group who did not have relapse were selected on a random basis. Histology, receptor status, AgNOR, DNA flow cytometry and various immunohistochemical parameters were compared between the groups with recurrence and that without recurrence. On univariate analysis, tumor size, immunohistochemical expressions of PCNA, MIB-1, c-erbB-2 and S-phase fraction were significantly different between the above two groups. By multivariate analysis, immunohistochemical c-erbB-2 expression (more than 50% of cancer cells) was an independent parameter. As a summary from our studies, c-erbB-2 immunohistochemical staining on paraffin sections might be the best independent prognostic factor in axillary node-negative breast cancers.

    Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These features are not typical of non-bifurcating ICA. The occipital artery originated from an anomalous connection in one instance and from the main trunk of the ECA (just past the ECA-ICA connection) in the other.

    Objective To compare the recent clinical effects between the laparoscopic axillary lymph node dissection and conventional axillary lymph node dissection. Methods Clinical data of 56 breast cancer patients underwent axillary lymph node dissection in the Second Department of General Surgery, the Third Xiangya Hospital from January to September,2010 were retrospectively analyzed. The recent clinical effects were compared between laparoscopic group and conventional group. Results The average amount of bleeding in laparoscopic group was less than that in conventional group (44.3ml vs 89.4ml, P<0.05). The average operation time of conventional group was shorter than that of laparoscopic group (70.5 min vs 92.5 min, P<0.05). No statistically significant difference was found in the average number of lymph nodes and the average number of positive lymph nodes between conventional group and laparoscopic group ( 16.9 vs 16.1, 3. 8 vs 3.5; P>0.05). One case of postoperative wound infection was found in laparoscopic group. Lymphatic fistula occurred in two cases of conventional group. Conclusions As compared with conventional axillary lymph node dissection, laparoscopic axillary lymph node dissection not only has the same effect in lymph node dissection but also has the advantages of minimal invasion,cosmetic surgery, and less complications. This method is worthy to be popularized in clinical application.%目的 比较腔镜腋窝淋巴结清扫术和常规手术近期临床疗效的差异.方法 回顾性分析2010年1-9月在中南大学湘雅三医院普外二科收治的56例行腋窝淋巴结清扫术的乳腺癌患者,比较腔镜组和常规组的近期临床疗效.结果 与常规组相比较,腔镜组平均手术出血量较少(44.3 ml vs 89.4 ml,P0.05).术后并发症中腔镜组有一例出现术后伤口感染,常规组有两例出现术后淋巴瘘.结论 乳腺癌腔镜腋窝淋巴结清扫术与传统手术相比较不但同样能彻底的清扫腋窝淋巴

    2016-01-01

    Throughout its 30-year history, the right gastroepiploic artery (GEA) has been useful for in situ grafts in coronary artery bypass grafting (CABG). The early graft patency rate is high, and the late patency rate has improved by using the skeletonized GEA graft and proper target selection, which involves having a target coronary artery with a tight >90% stenosis. Total arterial revascularization with the internal thoracic artery and GEA grafts is an option for achieving better outcomes from CABG procedures. PMID:27525230

    Subclavian artery pseudoaneurysm that induced from central venous catheterization through the internal jugular vein is relatively uncommon. However, the management of subclavian artery pseudoaneurysm remains a challenge because of their non-compressibility of deep locality and relationship to important surrounding anatomy, such as the origin of vertebral artery. In this paper, the authors report a patient with larger iatrogenic subclavian arterial pseudoaneurysm near the origin of vertebral artery, that was treated successfully by endovascular covered stent and coils.

  14. Determination of arterial wall shear stress

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The arteries can remodel their structure and function to adapt themselves to the mechanical environment. In various factors that lead to vascular remodeling, the shear stress on the arterial wall induced by the blood flow is of great importance. However, there are many technique difficulties in measuring the wall shear stress directly at present. In this paper, through analyzing the pulsatile blood flow in arteries, a method has been proposed that can determine the wall shear stress quantitatively by measuring the velocity on the arterial axis, and that provides a necessary means to discuss the influence of arterial wall shear stress on vascular remodeling.

    Maltz, Jonathan S; Budinger, Thomas F

    2014-03-04

    A "relaxoscope" (100) detects the degree of arterial endothelial function. Impairment of arterial endothelial function is an early event in atherosclerosis and correlates with the major risk factors for cardiovascular disease. An artery (115), such as the brachial artery (BA) is measured for diameter before and after several minutes of either vasoconstriction or vasorelaxation. The change in arterial diameter is a measure of flow-mediated vasomodification (FMVM). The relaxoscope induces an artificial pulse (128) at a superficial radial artery (115) via a linear actuator (120). An ultrasonic Doppler stethoscope (130) detects this pulse 10-20 cm proximal to the point of pulse induction (125). The delay between pulse application and detection provides the pulse transit time (PTT). By measuring PTT before (160) and after arterial diameter change (170), FMVM may be measured based on the changes in PTT caused by changes in vessel caliber, smooth muscle tone and wall thickness.

    1991-01-01

    Coronary artery fistula is an uncommon clinical entity. The most common coronary artery fistula is from the right coronary artery to the right side of the heart, and it is less frequent to the pulmonary artery. The effect of a coronary artery fistula may be physiologically significant because of the steal phenomenon resulting in coronary ischemia. Based on published reports, it is recommended that patients with congenital coronary artery fistulas be considered candidates for elective surgical correction to prevent complications including development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and coronary aneurysm formation with rupture or embolization. A patient is presented in whom treadmill-exercise thallium imaging was effective in determining the degree of coronary steal from a coronary artery fistula, leading to successful corrective surgery.

    2016-06-01

    Basilar artery thrombosis constitutes 1% of all types of stroke, carries a mortality rate of up to 90%, and is one of the rarer causes of sudden death. It leads to brain stem ischemia and commonly presents with impaired consciousness, cranial nerve palsy, hemiplegia or quadriplegia, and sudden collapse. Clinically, the diagnosis of basilar artery thrombosis is made on clinical symptoms, along with a hyperdense basilar artery in antemortem computed tomography (CT) scan. To our knowledge, whether a hyperdense basilar artery indicates basilar artery thrombosis on postmortem CT scan is not documented in the literature. We present a case report of a 55-year-old man who on postmortem CT scan showed a hyperdense basilar artery and was subsequently confirmed to be a fatal basilar artery thrombosis. We suggest that a hyperdense basilar artery on postmortem CT should prompt the pathologist to consider basilar artery thrombosis. PMID:27049662

    Background Some individuals have multiple renal arteries. Severe stenosis in one of the arteries may cause refractory hypertension. The detection of stenosis within one of the multiple renal arteries usually required invasive procedures, such as computed tomographic angiography (CTA) and magnetic resonance angiography (MRA). This study reported the application of color Doppler sonography (CDS) in the detection of severe stenosis in one of the multiple arteries.Methods Patients with multiple renal arteries and one of the arteries with severe stenosis were retrospectively studied. Peak systolic velocities (PSV) of renal arteries and the intrarenal CDS patterns were collected and compared. The diagnosis was confirmed by digital subtraction angiography (DSA).Results Four children with multiple renal arteries and one of the arteries with stenosis were investigated. They were admitted due to refractory hypertension. CDS screening identified two renal arteries in one kidney of each patient with one of the two renal arteries having stenosis >70%. The PSV of the stenosed arteries were much higher, and the intrarenal CDS patterns supplied by the stenosed arteries changed into T-P patterns.Conclusion Non-invasive CDS technology may be a useful method to identify severe stenosis in one of multiple renal arteries in young patients.

    Purpose: To compare the locoregional recurrence (LRR) rates in patients with nodal mirometastases (pNmic) with those in patients with node-negative (pN0) and macroscopic node-positive (pNmac) breast cancer; and to evaluate the LRR rates according to locoregional treatment of pNmic disease. Methods and Materials: The subjects were 9,616 women diagnosed between 1989 and 1999 with Stage pT1-T2, pN0, pNmic, or pNmac, M0 breast cancer. All women had undergone axillary dissection. The Kaplan-Meier local recurrence, regional recurrence, and LRR rates were compared among those with pN0 (n = 7,977), pNmic (n = 490) and pNmac (n = 1,149) and according to locoregional treatment. Multivariate analysis was performed to identify the significant factors associated with LRR. Results: The median follow-up was 11 years. The 10-year Kaplan-Meier recurrence rate in the pN0, pNmic, and pNmac cohorts was 6.1%, 6.8%, and 8.7% for local recurrence; 3.1%, 6.2%, and 10.3% for regional recurrence; and 8.0%, 11.6%, and 15.2% for LRR, respectively (all p < .001). In the pNmic patients, the 10-year regional recurrence rate was 6.4% with breast-conserving surgery plus breast radiotherapy (RT), 5.4% with breast-conserving surgery plus locoregional RT, 4.6% with mastectomy alone, 11.1% with mastectomy plus chest wall RT, and 10.7% with mastectomy plus locoregional RT. In patients with pNmic disease and age <45 years, Grade 3 histologic features, lymphovascular invasion, nodal ratio >0.25, and estrogen receptor-negative disease, the 10-year LRR rates were 15-20%. On multivariate analysis of the entire cohort, pNmic was associated with greater LRR than Stage pN0 (hazard ratio [HR], 1.6; p = .002). On multivariate analysis of pNmic patients only, age <45 years was associated with significantly greater LRR (HR, 1.9; p = .03), and trends for greater LRR were observed with a nodal ratio >0.25 (HR, 2.0; p = .07) and lymphovascular invasion (HR, 1.7; p = .07). Conclusion: Women with pNmic had a greater

    Full Text Available A pesquisa do linfonodo sentinela constitui tratamento padrão para pacientes portadoras de câncer de mama e axila clinicamente negativa. A presença do linfonodo sentinela (LS extra-axilar e intramamário (IM ocorre em até 2,6% dos casos, e na presença do LS IM metastático, a positividade axilar pode alcançar até 81%. Na associação do LS IM metastático ao LS axilar não metastático, não há conduta padronizada, visto um limitado número de casos descritos. Adicionamos dois casos à literatura, observando, em um deles, a presença de doença metastática axilar na linfadenectomia complementar. A utilização de nomograma demonstrou que o risco de doença metastática axilar era inferior a 10%, e a adição destes casos à literatura mostrou que, nesta situação, a taxa de doença metastática axilar é de 6,25%. Discutimos os prós e contras da linfadenectomia axilar complementar nesta situação.The sentinel lymph node biopsy is a standard treatment for patients with breast cancer and clinically negative axilla lymph node. The presence of an extra-axillary and intra-axillary (IM sentinel lymph node (SLN occurs in up to 2.6% of cases. In the presence of a metastatic IM SLN, axillary positivity may occur in up to 81% of cases. Due to the limited number of cases reported, there is no standard treatment for the association of metastatic SLN IM and non-metastatic axillary SLN . We add here two cases to the literature, one of them with metastatic disease in the axilla. The use of a nomogram demonstrated that the risk of axillary metastasis was less than 10% and the addition of these cases to the literature showed that in this situation the rate of axillary metastasis is 6.25%. We discuss the pros and cons of further axillary dissection in this situation.
