    Nipple discharge is a common symptom that is alarming for the patient since it can be a presenting symptom of breast cancer. Breast imaging is used to examine women with pathologic nipple discharge in order to detect any lesions that may be present and to assist in the differential diagnosis. The modalities of breast imaging include mammography, breast ultrasonography (US), and magnetic resonance imaging. Breast US is currently considered to be useful for the visualization of ductal structures and intraductal lesions that cause nipple discharge. In this review, we discuss US techniques that assist in the clear visualization of ductal structures and intraductal lesions in patients with nipple discharge. Controversy remains regarding the evaluation and management of patients with nipple discharge, and we summarize the results available in the currently published literature

    To compare the galactographic findings of malignant and benign disease in patients with pathologic nipple discharge and to analyze the features suggesting malignancy. In 24 patients in whom pathologic nipple discharge had occurred, the findings of preoperative galactography were correlated with those of pathology. Nine of the 24 cases were malignant and the other 15 were benign. Intraductal calcification occurred in five malignant cases (56%) and two (13%) which were benign. Seven malignant cases (78%) involved the segmental ducts, and in eight (89%), the peripheral ducts below the subsegmental duct were involved. Five benign cases (33%) involved the lactiferous sinus, seven (47%) the segmental duct, and two (13%) the subsegmental duct. Distal duct dilatation occurred in four benign cases (27%), while ductal stenosis was noted in six cases (67%) and ductal distortion in seven (78%). A malignant tumor appeared as a multiple (n=5, 56%) or irregular (n=5, 56%) filling defect, and a benign tumor as a single (n=12, 80%), oval (n=6, 40%) or lobular (n=4, 27%) filling defect. At galactography, a malignant tumor frequently appeared as an irregular multiple intraductal filling defect in a peripheral duct. A benign tumor, on the other hand, appeared as an oval or lobular single lesion. The presence of ductal stenosis, distortion and intraductal microcalcifications not opacified by contrast material suggest possible malignancy.

    The management of a pathological nipple discharge often involves surgery for the exclusion of a malignant etiology. This study aimed to determine the prevalence of cancer in patients who had microdochectomy for pathological nipple discharge in a population in South Africa and to evaluate patients' demographics and clinical characteristics as indicators of underlying cancer and make recommendations for their management in resource-limited settings. Clinical, radiological, and histological data from 153 patients who underwent a microdochectomy for a pathological nipple discharge at two South African breast clinics was collected. Invasive or in situ cancer was found in 12 patients (7.84%), and in all patients, cancer was associated with a bloody nipple discharge. Bloody discharge had a sensitivity of 100% in indicating cancer, specificity of 55.32%, positive predictive value of 16%, and negative predictive value of 100%. Patients with breast cancer were also more likely to be aged 55 y or older (P = 0.04). Preoperative mammogram and ultrasound were poor in detecting cancer (0/12). In our population, a bloody discharge in women aged 55 years or older should mandate a microdochectomy, with selective surgery for younger women and those with nonbloody discharges. Thorough clinical examination to determine the true color and nature of the discharge is vital in the initial assessment of these patients. Preoperative radiology is not helpful in determining the presence of cancer (in an isolated pathological nipple discharge), and microdochectomy still remains the gold standard in diagnosing cancer in these patients.

    Nipple discharge in non-lactating breast is classified as 2 groups. The first group is stagnation discharge which is determined by an apocrino-like exfoliation and stagnation within the ductal system. The second group is hyperplastic or neoplastic group. The secretory breast disease combined with nipple discharge can not be diagnosed by simple X-ray mammography of ultrasonography. For differential diagnosis of secretory breast disease and for localization of lesions, the galactography is necessary. We analysed 49 cases of galactography is non-lactating breat and obtained following results. 1. The most common cause of discharge was duct ectasis (39%) in stagnation discharge group and papilloma (23%) in hyperplastic discharge group. 2. Hyperplastic discharge group occurred most frequently in 5th decade of age and was discovered more frequently in fatty parenchymal pattern on simple mammography. 3. The most frequent type of nipple discharge was cloudy-milky type in stagnation group and bloody nature in hyperplastic group. 4. The most common cause of bloody discharge was papilloma (58%). 5. The bloody nipple discharge among 56 cases of breast cancer during 4 years occurred only in 5 cases (9%)

    Nipple discharge is a relatively frequent initial symptom of a pathologic lesion in the nonlactating breast which brings the patient to the physician for treatment. Eventhough only stressful significance of a sanguineous discharge, all type of nipple discharge will indicate that abnormal nipple discharge is a symptom of a pathologic change in the ductal and secretery susrem of the breast, and galactogram often offers information to etiology. Galactography using water soluble contrast media is a valuable procedure to evaluate women with nonlactational nipple discharge or bleeding which are usually due to benign diseases such as intraductal papilloma, papillomatosis, secretory disease or malignant lesions. Contrast galactography can often accomplish such localization and sometimes can suggest or confirm the nature of the pathologic process. Authors have experienced 5077 cases of mammograms, and among them, 195 cases with nipple discharge have been at Youndong Severance Hospital. Yonsei University since October 1, 1983 through June 10, 1988. The results were: 1. Incidence of non lactating nipple discharge was 3.9% among 5077 cases. 2. Most frequent histopathologic disease among surgically confirmed 100 cases was papilloma (35%), which was followed by papillomatosis (28%), fibrocystic disease (14%) and then breat carcinoma (13%). 3. Age distribution of patient of nonlactating nipple discharge showed no differences in comparing to the patients with the same histopathologic disease without nipple discharge. 4. Bloody nipple discharge is the commonest finding (61%) which was followed by serous (22%), milkish (8%), and then seroanguinous (5%) nipple discharge, in analyzing relationship between histopathologic diagnosis and nipple discharge, papilloma and papillomatosis had bloody nipple discharge (69%, 57%), frequently and serous nipple discharge (26%, 25%). Breat cancer had mostly bloody nipple discharge (85%), in contrast to the fibrocystic disease which showed 50

    Isolated bloody nipple discharge is rare in infancy and is usually idiopathic. Discharge commonly resolves spontaneously, and ultrasonography is a useful diagnostic technique to detect the cause of discharge. The authors report a 7-month-old boy who presented with unilateral spontaneous bloody nipple discharge for 1 month without signs of infection or mass.

    To test the milk flow rates and variability in flow rates of bottle nipples used after hospital discharge. Twenty-six nipple types that represented 15 common brands as well as variety in price per nipple and store location sold (e.g., Babies R' Us, Walmart, Dollar Store) were chosen for testing. Ten of each nipple type (n = 260 total) were tested by measuring the amount of infant formula expressed in 1 minute using a breast pump. Mean milk flow rate (mL/min) and coefficient of variation (CV) were calculated. Flow rates of nipples within brand were compared statistically. Milk flow rates varied from 1.68 mL/min for the Avent Natural Newborn Flow to 85.34 mL/min for the Dr. Brown's Standard Y-cut. Variability between nipple types also varied widely, from .03 for the Dr. Brown's Standard Level 3 to .37 for MAM Nipple 1 Slow Flow. The extreme range of milk flow rates found may be significant for medically fragile infants being discharged home who are continuing to develop oral feeding skills. The name of the nipple does not provide clear information about the flow rate to guide parents in decision making. Variability in flow rates within nipples of the same type may complicate oral feeding for the medically fragile infant who may not be able to adapt easily to change in flow rates. Both flow rate and variability should be considered when guiding parents to a nipple choice.

    To investigate diagnostic value of imaging procedures and management strategies of the patients with nipple discharge (ND) to establish management recommendations. Bibliographical search in French and English languages by consultation of PubMed, Cochrane and Embase databases. Although, all ND require an systematic evaluation guided by clinical data, bloody ND could be a predictor of breast cancer risk among different colors of discharge particularly in patients of more than 50 years (LE2). The mammography and breast ultrasography are the imaging procedures to realize in first intention (grade C) but they turn out useful only when they detect radiological abnormalities (LE4). Galactography has only a localizing value of possible ductal abnormalities (when standard imaging procedures is not contributive) (LE4). Thus, in the diagnostic investigation of a suspicious ND, galactography it is not recommended in standard practice (grade C). The breast Magnetic Resonance Imaging (MRI) is recommended when breast standard imaging procedures are not contributive (grade C). The ND cytology is useful only if it is positive (i.e. reveal cancer cells). There is no proof on the diagnostic performance of the cytological analysis of the ND to allow a recommendation on its realization or not. In front of a suspicious ND, when breast-imaging procedures reveals an associated radiological lesion, an adapted percutaneous biopsy is recommended by percutaneous way (grade C). Vacuum-assisted breast biopsies is a diagnostic tool but can also be therapeutic allowing to avoid surgery in case of benign lesion but current literature data do not allow recommendations on the therapeutic aspect of vacuum-assisted breast biopsy (LE4). In the absence of associated radiological signal, and in case of reproducible bloody persistent ND, a pyramidectomy is recommended (grade C). Copyright © 2015 Elsevier Masson SAS.

    Purpose: To retrospectively review the outcome of conservatively treated breast cancer patients who present with nipple discharge at initial diagnosis. Methods and Materials: The charts of 1097 patients undergoing conservative surgery and radiation therapy between January 1970 and December 1990 were reviewed. All patient data, including clinical, pathologic, treatment, and outcome variables were entered onto a computerized database. For the current study, specific attention was directed to the initial presenting symptoms and patients were divided into two groups: those presenting at initial diagnosis with nipple discharge (D/C-YES, n = 17), and those presenting without nipple discharge (D/C-NO, n = 1080). Results: As of August 1998, with a median follow-up of 12 years, the 10-year actuarial survival, distant metastasis-free survival, and breast relapse-free survival rates for the overall population were 73%, 78%, and 83%, respectively. Although the D/C-YES and D/C-NO groups were well balanced with respect to the majority of clinical factors, the D/C-YES patients had a higher percentage of DCIS histology (7.3% vs 1.2%, p < 0.01), were less likely to undergo reexcision (12% vs 35%), and were more frequently under age 40 (35% vs 12%) than the D/C-NO patients. Over the time span of this study, status of the final surgical margin was indeterminate in the majority of cases. Local relapses occurred in 6 of the 17 patients in the D/C-YES group, resulting in a 10-year actuarial breast relapse-free survival rate of 50%, which was significantly lower than the 10-year breast relapse-free survival rate of 86% in the D/C-NO population. Among the patients presenting with nipple discharge, those with sacrifice of the nipple areolar complex had a lower local relapse rate than those patients who had conservation of the nipple areolar complex (20% vs 42%), although this difference did not reach statistical significance. Conclusions: Although patients presenting with nipple discharge

    Galactogrpahy was performed in 204 women with a nipple discharge and the secretion confirmed histopathologically. All 116 intraductal tumors (papilloma, papillomatosis, carcinoma), which were associated with a serous or bloody discharge, were detected preoperatively. A palpable mass had little diagnostic significance, and exfoliative cytology was positive in only 11% (2/18) of the patients with carcinoma. The authors recommend that all patients with a spontaneous bloody or serous discharge from a single lactiferous orifice undergo galactography in addition to physical, cytological, and mammographic examination. Intraductal injection of methylene blue dye will demonstrate the affected duct system to the surgeon and can often make surgery less radical or even unnecessary

    Full Text Available Nipple discharge is the third most common breast complaint after breast pain and breast mass, most commonly associated with endocrine alterations and/or medications, pregnancy, lactation, post lactation, fibrocystic disease, intraductal papilloma, duct ectasia, nipple adenoma, infection, chronic mastitis, subareolar abscess, and least frequently, breast carcinoma. Cytological examination of nipple discharge (ND is a noninvasive method of diagnosing the underlying breast pathology. We report a 46 year old female, who presented with pain and blood-mixed ND from the right breast with an impalpable mass. Cytological examination of the discharge was done and diagnosis of papillary neoplasm with degeneration, metaplasia, and atypia was given, which was further confirmed on histology and positive IHC for HMWCK and p63. Final diagnosis was intraductal papilloma of the lactiferous duct with squamous metaplasia and infarction. Differentiating benign papilloma from a carcinoma is challenging to the cytopathologist and requires clinicopathological correlation and a good knowledge of cytology.

    To compare 3.0 Tesla breast magnetic resonance imaging (MRI) with galactography for detection of benign and malignant causes of nipple discharge in patients with negative mammography and ultrasound. We prospectively evaluated 56 breasts of 50 consecutive patients with nipple discharge who had inconspicuous mammography and ultrasound, using 3.0 Tesla breast MRI with a dedicated 16-channel breast coil, and then compared the results with galactography. Histopathological diagnoses and follow-ups were used as reference standard. Lesion size estimated on MRI was compared with the size at histopathology. Sensitivity and specificity of MRI vs. galactography for detecting pathologic findings were 95.7 % vs. 85.7 % and 69.7 % vs. 33.3 %, respectively. For the supposed concrete pathology based on MRI findings, the specificity was 67.6 % and the sensitivity 77.3 % (PPV 60.7 %, NPV 82.1 %). Eight malignant lesions were detected (14.8 %). The estimated size at breast MRI showed excellent correlation with the size at histopathology (Pearson's correlation coefficient 0.95, p 3.0 Tesla is an accurate imaging test and can replace galactography in the workup of nipple discharge in patients with inconspicuous mammography and ultrasound. • Breast MRI is an excellent diagnostic tool for patients with nipple discharge. • MRI of the breast reveals malignant lesions despite inconspicuous mammography and ultrasound. • MRI of the breast has greater sensitivity and specificity than galactography. • Excellent correlation of lesion size measured at MRI and histopathology was found.

  18. Nipple Discharge: An Early Warning Sign of Breast Cancer

    Nipple discharge (ND) can be the earliest presenting symptom of breast cancer. We hereby present two cases of breast cancer with no palpable mass manifesting as isolated ND, which was whitish in color. In both cases, cytology of the discharge revealed highly pleomorphic cells indicating a high grade malignancy. Mammography showed diffuse, extensive microcalcifications. Simple mastectomy with axillary clearance was done. Histology in both cases revealed diffusely spreading intraductal carcinoma, with focus of microinvasion in one case. ND if scanty or not blood stained is often ignored by the patients and at times, the clinicians. This article highlights that ND can be an early warning sign of intraductal carcinomas that are non-invasive in early stage. Irrespective of the color or nature of the discharge, unilateral ND needs to be evaluated. Proper clinical assessment, cytological evaluation of the ND, and mammography ought to be performed in all such cases. Considering the low level of awareness in women regarding the warning signs of breast cancer, the current focus is to create “breast awareness.” Women should be sensitized to recognize any unusual changes in their breasts and report to their health care providers at the earliest.

    Full Text Available The role of nipple discharge cytology (NDc in the surgical management of breast cancer patients is unclear. We aimed: (i to evaluate the effect of malignant NDc on the surgical approach to the nipple-areola complex, and (ii to verify the association between malignant NDc and nipple malignancy.We retrospectively analyzed a case series of 139 patients with NDc who underwent breast surgery. The clinical and histological findings, types of surgery with emphasis on nipple-areola complex amputation, immunohistochemical phenotypes of the carcinomas and measurements of the tumor-nipple distance were recorded. Additionally, in patients who showed HER2-positive lesions on definitive surgery, we evaluated the HER2 immunocytochemistry of the NDc smears.Thirty-two malignant and 107 benign/borderline NDc diagnoses were identified. All 32 malignant-NDc cases were histologically confirmed as malignant. Thirty borderline/benign-NDc cases were histologically diagnosed as malignant (sensitivity 58%. The majority of the patients with malignant NDc were treated with nipple-areola complex amputations in both the mastectomy and conservative surgery groups (P<0.001, χ251.77. Nipple involvement was strongly associated with HER2-positive ductal carcinoma in-situ (P<0.001, χ211.98. HER2 immunocytochemistry on the NDc revealed a 100% correlation with the immunocytochemistry performed on the surgical tissues.Malignant NDc influenced surgical management. The association of malignant NDc with nipple involvement is highly related to ductal carcinoma in-situ with HER2 overexpression. In case of HER2 positive NDc, nipple-areola complex involvement is more likely than in HER2 negative cases.

  1. Bloody Nipple Discharge in an Adolescent Girl: Unusual Presentation of Juvenile Fibroadenoma

    Full Text Available Fibroadenoma accounts for 50–60% of all breast mass lesions in adolescents. It usually presents as a unilateral palpable breast mass. In contrast, bloody nipple discharge rarely occurs in childhood. We report the case of a 12-year-old pubertal girl who presented with a solitary breast mass and bloody nipple discharge. Physical examination and ultrasound showed a right breast subareolar homogenous mass, about 2.5 cm in diameter, near the lactiferous duct. Histologic diagnosis of the mass revealed a juvenile fibroadenoma with infarction and hemorrhage. The unusual clinical presentation and possible etiology in this patient is described, and the proper management of bloody nipple discharge in pediatric patients is discussed in association with a literature review.

    To assess the contribution of mammography and ultrasound in men with nipple discharge. All men with nipple discharge who underwent mammography and/or ultrasound between 1993 and 2011 in our hospital were retrospectively evaluated. Radiological findings were classified according to BI-RADS lexicon. The final diagnosis was made based on histopathological results or clinical-radiological follow-up. The diagnostic performance of physical examination, mammography and ultrasound was calculated and compared. 26 men with 21 mammograms and 19 ultrasounds were reviewed. The final diagnoses were: 6 carcinomas (23.1%), 10 gynaecomastias, 2 pseudogynaecomastias and 8 normal breast tissues. Mammograms and ultrasounds performed on all five patients with infiltrating carcinoma showed a mass (categories 4 and 5). In all these patients except one, a breast mass was also noted and the physical examination was positive or suspected malignancy. In the patient with carcinoma in situ, the only conspicuous clinical sign was bloody nipple discharge and the mammography showed calcifications (category 4) that were not visible on ultrasound. Radiological findings of all patients without malignancy were classified as categories 1 and 2. The diagnostic performance of physical examination was lower than mammography and ultrasound (P>0.05). Mammography was more sensitive than ultrasound (100% vs. 83.3%). Both techniques showed the same specificity (100%). Men with nipple discharge have a high incidence of breast carcinoma. Nipple discharge may be the only clinical sign of carcinoma in situ. Mammography and ultrasound are useful in the evaluation of men with nipple discharge, diagnosing carcinoma in initial stages, avoiding unnecessary biopsies. Copyright © 2012 Elsevier Ireland Ltd.

    2013-10-01

    Full Text Available A 44-year-old woman was referred to our hospital with pathological nipple discharge from her left breast. Ultrasonography revealed a solid tumor beneath her left areola that measured 17 mm in diameter with a dilated mammary duct. Contrast-enhanced magnetic resonance imaging showed an early-enhanced cystic tumor and a dilated mammary duct. We performed a duct-lobular segmentectomy using near-infrared indocyanine green (ICG-fluorescence imaging. Under general anesthesia, a silicone tube was inserted into an orifice of a fluid-discharging mammary duct, and 1 mL dye-fluorescence liquid containing ICG and indigo carmine was injected into the mammary duct. A periareolar incision was made, and the fluorescence image of the demarcated mammary duct segment was obtained. The mammary duct segment was dissected, along with the demarcation line. The cystic lesion and dilated mammary duct were fully resected, and the pathological diagnosis was intraductal papilloma of the breast. We report that near-infrared ICG fluorescence could be applied for imaging of the mammary duct segment, and the fluorescence image allowed for easier duct-lobular segmentectomy for nipple discharge.

    Full Text Available The primary role of fine needle aspiration (FNA of the breast is the distinction between benign and malignant lesions; but in many cases, additional information may be obtained. The major breast lesions that yield papillary fragments on FNA are papillary carcinoma, papilloma, fibroadenoma, and invasive ductal carcinoma that have a papillary component. We present cytomorphological features of nipple discharge and FNA of breast lump in a 32-year female.

    Comparing the sensitivity of Contrast-Enhanced Magnetic Resonance Imaging (CEMRI), mammography and ultrasonography in patients with nipple discharge (ND). We retrospectively evaluated 38 women with ND who underwent mammography, ultrasound and 1.5 T CEMRI between March 2007 and July 2009. Imaging findings, pathological diagnosis and follow-up data (mean follow-up: 20 months) were compared. Sensitivity and specificity values were reckoned. Statistical differences in sensitivity were assessed. 5/38 malignancies (13.2%; 3 invasive, 2 intraductal; 4 ipsilateral, 1 contralateral to ND), and 14/38 High-Risk Lesion (HRL - 36.8%; 11 intraductal papillomas, 1 papilloma with LCIS, 1 sclerosing papilloma and 1 atypical intraductal hyperplasia, all ipsilateral) were found. CEMRI identified 5/5 cancers and 13/14 HRL (Overall Sensitivity - OSS = 94.7%; Overall Specificity - OSP = 78.9%). 3/5 cancers (1 invasive, 1 in-situ; 1 invasive contralateral) and 2/14 HRL were detected by CEMRI only. Mammography found 2/5 cancer and 3/14 HRL (OSS = 26.3%; OSP = 94.7%). Ultrasound identified 1/5 cancer and 11/14 HRL (OSS = 63.2%; OSP = 84.2). 1/14 HRL was detected by ultrasound only. Compared with mammography and ultrasound, CEMRI showed statistically significantly higher OSS values (p < 0.0001, p = 0.042 respectively). In women with ND, CEMRI should be recommended when conventional imaging is negative. Unexplained ND could be considered an indication for CEMRI. (orig.)

  6. Male ductal carcinoma in situ presenting as bloody nipple discharge: a case report and literature review.

    Male breast carcinoma accounts for 1% of all diagnosed breast carcinoma. Pure ductal carcinoma in situ in men is extremely rare. Unfortunately, male breast cancer is often diagnosed at a late stage because of the minimal awareness of presenting symptoms by the patient and sometimes by the health care provider. Because of this late presentation, the overall prognosis is less favorable. This case is presented to emphasize the importance of recognizing bloody nipple discharge as a clinical sign of male ductal carcinoma in situ and an opportunity for early diagnosis.

    Bloody nipple discharge in adults is, in men as well as in women, often a symptom of an underlying malignant disease. In respect of this, multiple invasive and mutilating diagnostic procedures have been performed in infants and older children. Apart from individual cases in older and pubertal children, in childhood benign conditions are most common and can be diagnosed by non-invasive diagnostic procedures. Here we discuss a rational diagnostic approach on the basis of 2 patients with bloody nipple discharge at the age of 8 and 9 months which resolved spontaneously without treatment after 3 and 6 months, respectively.

    Mammary ductoscopy (MD) is commonly used to detect intraductal lesions associated with nipple discharge. This study investigated the relationships between ductoscopic image-based indicators and breast cancer risk, and developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge. A total of 879 consecutive inpatients (916 breasts) with nipple discharge who underwent selective duct excision for intraductal neoplasms detected by MD from June 2008 to April 2014 were analyzed retrospectively. A nomogram was developed using a multivariate logistic regression model based on data from a training set (687 cases) and validated in an independent validation set (229 cases). A Youden-derived cut-off value was assigned to the nomogram for the diagnosis of breast cancer. Color of discharge, location, appearance, and surface of neoplasm, and morphology of ductal wall were independent predictors for breast cancer in multivariate logistic regression analysis. A nomogram based on these predictors performed well. The P value of the Hosmer-Lemeshow test for the prediction model was 0.36. Area under the curve values of 0.812 (95 % confidence interval (CI) 0.763-0.860) and 0.738 (95 % CI 0.635-0.841) was obtained in the training and validation sets, respectively. The accuracies of the nomogram for breast cancer diagnosis were 71.2 % in the training set and 75.5 % in the validation set. We developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge based on MD image findings. This model may aid individual risk assessment and guide treatment in clinical practice.

    To evaluate whether the removal of an intraductal mass using an ultrasound (US)-guided directional vacuum-assisted device can eliminate symptoms in patients presenting with abnormal nipple discharge. Between March 2004 and October 2006, 36 patients who presented with abnormal nipple discharge, underwent US-guided, 11-gauge vacuum-assisted biopsy for a benign intraductal single mass on US. The ability of the procedure to eliminate nipple discharge was evaluated by physical examination during follow-up US. Lesion characteristics, biopsy variables, and histologic features were analyzed to identify factors affecting symptom resolution. Of the 36 lesions, 25 (69%) were intraductal papillomas, 10 (28%) were fibrocystic changes, and one (3%) was a fibroadenoma. The nipple discharge disappeared in 69% (25 of 36) of the women at a mean follow-up time of 25 months (range 12-42 month). There was no difference in the lesion characteristics, biopsy variables, and the histologic features between groups that eliminated the symptom compared those with persistent nipple discharge. US-guided directional vacuum-assisted removal of an intraductal mass appears to eliminate nipple discharge in only 69% of patients and thus, it should not be considered as an alternative to surgical excision.

    2007-01-01

    Ductitis obliterans or mastitis obliterans is a rare late manifestation of mammary ductal ectasia. We describe a long-term diabetic patient who presented with bilateral bloody nipple discharge and poorly defined nodularities around the nipple of both breasts. The ductography showed multiple segments of irregular ductal narrowing and intraluminal filling defects in both breasts. The bilateral resection of the sub-areolar portion of the breast showed exuberant fibrous obliteration of the large- and medium-sized ducts by granulation tissue associated with few histiocytes. Ductal dilatation and intraductal accumulation of histiocytes was also present. This represents a late and florid form of mammary ductal ectasia. Differential diagnostic considerations including fibrocystic changes, diabetic sclerosing lymphocytic lobulitis, idiopathic granulomatous lobular mastitis, and periductal mastitis (Zuska disease) are discussed. Accurate diagnosis can help avoid or limit radical surgeries in this group of patients.

    This research investigated the effects of different breastfeeding training techniques for primiparous mothers before discharge on the incidence of cracked nipples. This was a controlled intervention study that was carried out between 2015 and 2016 on 90 mothers living in İzmir. The mothers were divided into three groups: the demonstration-based training group, brochure group, and routine care-receiving group. The mothers in the "brochure group" were provided with breastfeeding training brochures. Mothers in the demonstration-based training group received one-to-one training using designed doll and puppet tools. The rate of cracked nipples at age 2 weeks was 63.3% in the routine care-receiving group, 56.7% in the brochure group, and 20% in the demonstration-based training group. At the end of the fourth week, the rate was 30% in the routine care-receiving group and less than 10% in the other two groups (p raining group than in the other two groups (p roups in the percentage of exclusive breastfeeding. The results documented that breastfeeding training based on one-to-one demonstration utilizing specially designed audiovisual tools was more effective than the other two methods in the prevention of nipple cracks.

    Improvement of imaging by injecting contrast agents into the discharging duct and immobilizing the breast mound with a drape-type thermoplastic shell in breast conserving surgery was assessed by evaluating 96 cases of breast cancer patients with nipple discharge treated by partial mastectomy between April 1998 and August 2003. These patients were divided to three groups: Group A was treated by ordinary partial mastectomy or microdochectomy without new methods. Group B underwent contrast imaging without shell immobilization, and Group C received both shell immobilization and contrast imaging. The negative rates of surgical margins in Groups A, B and C were 19.0%, 17.2%, and 37.5%, respectively. The rates of negative ''lateral'' surgical margins in Groups A, B and C were 23.8%, 27.6%, and 50%, respectively. The rate of negative ''lateral'' surgical margins in Group C was significantly higher than that in Group A. Our findings suggest CT-guided thermoplastic assisted segmentectomy, adopting both ductography CT and immobilization by shell, is an optimal breast conserving surgery for breast cancer with nipple discharge.

    Leiomyoma of the nipple is a rare, benign, non-epithelial tumor that is thought to arise from smooth muscle fibers in the subareolar tissue of the breast. We report an unusual case of leiomyoma of the nipple in a 32-year-old woman in whom the diagnosis was made by ultrasound-guided core needle biopsy. She came to our hospital complaining of a recently enlarged nipple with discharge and erosion in the region of the left nipple-areolar complex. This mass was evaluated by mammography, ultrasonography, and magnetic resonance imaging (MRI). To the best of our knowledge, this is the first case of a leiomyoma of the nipple examined by MRI. MRI showed an oval mass with circumscribed margins that appeared as an intermediate signal intensity on both T1- and T2-weighted images. A dynamic MRI study showed a rim-enhancing oval mass with delayed persistent enhancement. Ultrasound-guided core needle biopsy revealed spindle cell proliferation consistent with leiomyoma of the nipple

  15. Nipple Reduction With the Chullo-Hat Technique.

    Although various techniques of nipple reduction have been described in the literature, many are difficult to design or have unreliable outcomes. For men, as well as women who do not plan to breastfeed, it is not necessary to apply a complicated technique that protects the lactiferous ducts. The authors introduce a simple technique for nipple reduction that has achieved consistent, reproducible results. The desired nipple length is marked, and a chullo-hat excision pattern is drawn. After infiltration of a local anesthetic solution around the nipple, excision of the excess nipple tissue is performed, comprising 2 triangular flaps. The remaining 2 pillars are approximated with 5-0 Nylon simple interrupted sutures. However, the wound is not completely closed in the central area of the nipple, which promotes the drainage of discharge. Fifty-three women (106 nipples) underwent this surgery between December 2009 and December 2013. The follow-up period ranged from 6 months to 2 years (mean, 10 months). No major complications occurred, and the scars were very inconspicuous. The postoperative appearance of nipples was consistently similar in size and shape. This simple technique was safe and effective in nipples of different sizes. The results were reliable and consistent with expectations. Although this study included only women, the authors believe that outcomes would be successful in men as well. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Molluscum contagiosum is a virus-induced dermatologic condition causing characteristic pearly lesions on the surface of skin. The lesion is common in children. In adults, it is usually a sexually transmitted disease. Molluscum contagiosum may be found anywhere on the body, although it rarely occurs on the palms and soles. Dermatosis of nipple due to molluscum contagiosum is rare. If it occurs, it is accompanied by lesions in other sites. Isolated involvement of nipple by the virus is unusual and has been reported only once in previous literature to the best of our knowledge. Here, we report this unusual case of isolated molluscum contagiosum of nipple in 30-year-old female.

    Nipple adenoma is a very uncommon, benign proliferative process of lactiferous ducts of the nipple. Clinically, it often presents as a palpable nipple nodule, a visible nipple skin erosive lesion, and/or with discharge from the surface of the nipple skin, and is primarily seen in middle-aged women. Resultantly, nipple adenoma can clinically mimic the presentation of mammary Paget's disease of the nipple. The purpose of our current case report is to present a comprehensive review of the available data on nipple adenoma, as well as provide useful information to health care providers (including dermatologists, breast health specialists, and other health care providers) who evaluate patients with dermatologic conditions of the breast skin for appropriately clinically recognizing, diagnosing, and treating patients with nipple adenoma. Fifty-three year old Caucasian female presented with a one year history of erythema and induration of the skin of the inferior aspect of the right nipple/areolar region. Skin punch biopsies showed subareolar duct papillomatosis. The patient elected to undergo complete surgical excision with right central breast resection. Final histopathologic evaluation confirmed nipple adenoma. The patient is doing well 31 months after her definitive surgical therapy. Since nipple adenoma represents a benign proliferative process of the nipple, complete surgical excision is curative. However, the coexistence of nipple adenoma and ipsilateral or contralateral breast cancer is well reported in the literature. The potential for a direct causal link or association of nipple adenoma and breast cancer cannot be fully excluded.

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

    The purpose of this series was to review the spectrum of clinical and sonographic features associated with infection after nipple piercing. Between 2002 and 2010, 6 patients presented to our breast center with a breast abscess after nipple piercing. A retrospective analysis of the imaging findings was performed with clinical and pathologic correlation. Patients with breast infections after nipple piercing tend to be young, and the timing since piercing varies from 2 weeks to 17 months. Sonography showed a complex or hypoechoic mass in 5 of 6 patients. Treatment of breast abscesses included surgical incision and drainage, percutaneous drainage, and antibiotic therapy. Surgical evacuation is commonly performed; however, sonographically guided aspiration may be an appropriate management strategy.

    Full Text Available Intraductal breast diseases are characterized by a high risk of transformation in breast cancer. Difficulties of diagnosing intraductal lesions are associated with the only symptom — the appearance of pathologic discharge from the breast nipple. In adolescent girls, taking into account the immaturity of the nipple and it flatness, there are difficulties with removing it correctly. On physical examination, as well as with the high density of the surrounding tissue and areola, the control over the presence of pathologic discharge from the mammary ducts is difficult. The intraductal pathology requires ultrasound examination, mammography, and only after a full examination — ductographic research. The article presents its own clinical observations of the intraductal pathology in adolescent girls aged 14 and 15 years. The algorithms of examination and patient surveillance with intraductal pathology are described.

    Hyperkeratosis of the nipple and areola is a rare condition. We report two cases of hyperkeratosis of the nipple and areola occurring in men with no underlying endocrinopathy or synthetic estrogenic drug therapy. Both patients demonstrated prompt resolution of the hyperkeratosis of the nipples with a keratolytic gel. Because our cases were not associated with ichthyosis or epidermal nevus, they best fit into the category of nevoid hyperkeratosis of the nipples.

    Full Text Available Background: Nipple fissure is a common disorder during breastfeeding. With high prevalence of nipple fissures and its impacts on breastfeeding, as well as the existence of evidence in favor of the application of peppermint as an antiinflammatory and antiinfection herb, the purpose of this study is to determine the effect of Menthol essence on improving nipple fissures in the primiparous breastfeeding women. Materials and Methods: This study was conducted using a clinical trial method. Samples were divided randomly into two groups of 55 women. The women in the peppermint group applied four drops of Menthol essence on their nipple and areola after each feeding. The control group applied four drops of their own milk on the nipple and areola after each feeding. Then, the two groups were studied on days 10 and 14 postpartum. For intensity of pain, the visual analog scale (0-10 cm and to measure the severity of damage, Amir scale (1-10 cm were applied and the existence or lack of nipple discharge was also recorded. The data were analyzed using SPSS 17 software. Results: The mean intensity of pain and nipple fissure before treatment (8.55 ± 1.74 and day 10 after delivery (4.26 ± 1.57 and before treatment and day 14 after delivery in the case group (1.32 ± 1.02 had a significant difference (P < 0.001. Nipple discharge between the two groups, before treatment (%75.2 and day 10 after delivery (%31.6 and before treatment and day 14 after delivery (%15.7, the case group had a significant difference (P < 0.001. Conclusion: Menthol essence can improve nipple fissures in the primiparous breastfeeding women.

    Nipple-areolar complex (NAC) reconstruction is the final step in the long journey of breast reconstruction for mastectomy patients. Successful NAC reconstruction depends on the use of appropriate surgical techniques that are simple and reliable. To date, numerous techniques have been used for nipple reconstruction, including contralateral nipple sharing and various local flaps. Recently, it has been common to utilize local flaps. However, the most common nipple reconstruction problem encountered with local flaps is the loss of nipple projection; there can be approximately 50% projection loss in reconstructed nipples over long-term follow-up. Several factors might contribute to nipple projection loss, and we tried to overcome these factors by performing nipple reconstructions using a boomerang flap technique, which is a modified C-V flap that utilizes the previous mastectomy scar to maintain long-term nipple projection.

    Full Text Available Figure 1 is a picture of a 48-year-old male patient who presents with progressive painful enlargement of the areolae of 10 months’ duration. There was no bleeding or nipple discharge. He was diagnosed with human immunodeficiency virus (HIV infection 16 months ago and was initiated on antiretroviral therapy (ARV, which consisted of zidovudine, lamivudine and efavirenz. As his CD4 cell count at diagnosis was less than 200 cells/mm3, he was prescribed trimethoprim-sulphamethoxazole (Bactrim for prophylaxis against pneumonia due to pneumocystis jirovecii. Physical examination was unremarkable except for bilateral breast enlargement and right-sided old shingles scar in the T4 dermatome distribution.

    Full Text Available A nipple shield is a breastfeeding aid with a nipple-shaped shield that is positioned over the nipple and areola prior to nursing. Nipple shields are usually recommended to mothers with flat nipples or in cases in which there is a failure of the baby to effectively latch onto the breast within the first two days postpartum. The use of nipple shields is a controversial topic in the field of lactation. Its use has been an issue in the clinical literature since some older studies discovered reduced breast milk transfer when using nipple shields, while more recent studies reported successful breastfeeding outcomes. The purpose of this review was to examine the evidence and outcomes with nipple shield use. Methods: A literature search was conducted in Ovid MEDLINE, OLDMEDLINE, EMBASE Classic, EMBASE, Cochrane Central Register of Controlled Trials and CINAHL. The primary endpoint was any breastfeeding outcome following nipple shield use. Secondary endpoints included the reasons for nipple shield use and the average/median length of use. For the analysis, we examined the effect of nipple shield use on physiological responses, premature infants, mothers’ experiences, and health professionals’ experiences. Results: The literature search yielded 261 articles, 14 of which were included in this review. Of these 14 articles, three reported on physiological responses, two reported on premature infants, eight reported on mothers’ experiences, and one reported on health professionals’ experiences. Conclusion: Through examining the use of nipple shields, further insight is provided on the advantages and disadvantages of this practice, thus allowing clinicians and researchers to address improvements on areas that will benefit mothers and infants the most.

    2013-01-01

    Full Text Available This study aimed to assess the prevalence of pathological vaginal discharge and to describe risk factors associated with pregnant women. All women living in the city of Rio Grande, Southern Brazil, who gave birth in 2010 were included in the study. A standardized questionnaire was administered to collect information on demographic, reproductive, and health-related factors and morbidity during pregnancy. The chi-square test was used to compare proportions, and multivariate Poisson regression with robust variance was performed. Of the 2,395 women studied, 43% had pathological vaginal discharge during pregnancy. The adjusted analysis showed that younger women of lower socioeconomic condition, those with a past history of abortion, vaginal discharge in a previous pregnancy, and treated for depression, anemia, and urinary tract infection during their current pregnancy, were more likely to have pathological vaginal discharge. Vaginal discharge during pregnancy was highly prevalent in the sample studied calling for proper risk factor management at the primary care level.

    This study aims to analyze the variables on which depends therapeutic discharge, in patients with a severe dual diagnosis admitted to a professional therapeutic community where their pathology is treated. 325 patients admitted between June 2000 and June 2009 to the therapeutic community. This is a retrospective, cross-sectional study with no control group, based on the detailed analysis of the information collected in a model of semi-structured clinical interview designed in the therapeutic community. The 29.5% of the individuals included in the sample were therapeutically discharged. Of all the variables introduced in this analysis the most significant ones were gender, age at the beginning of treatment, education level, opiate dependence, polidrug abuse, and the presence of psychotic disorders and borderline personality disorder. In our study, gender determines the type of discharge, being therapeutic discharge more frequent among women. A higher educational also increases a better prognosis with a higher rate of therapeutic discharge among individuals with higher education level. A later age at the beginning of the treatment reduces the likelihood of therapeutic discharge. Likewise, polidrug abuse, diagnosis of psychotic disorders and borderline personality disorder are associated to a lower rate of therapeutic discharge. Recognizing these characteristics will allow the early identification of those patients more at risk of dropping treatment hastily, while trying to prevent it by increasing the therapeutic intensity.

    Literature on hyperprolactinemia in the setting of a nipple piercing is limited to individuals with concomitant breast/chest wall infection. It is unclear if chronic nipple stimulation from a piercing alone can cause sustained elevations of serum prolactin. Nipple piercing is emerging as a more mainstream societal form of body art, and the answer to this clinical question would potentially alter patient management. Our aim was to assess serum prolactin levels in subjects with nipple piercing. Inclusion criteria were as follows: men and women ≥ 18 years old with nipple piercing(s) present > 6 months. Exclusion criteria included: women who are pregnant, lactating or men and eight women were enrolled. Median (range) ages for men and women were 33 (24-42) and 27 years (23-42), respectively. All except one subject had bilateral piercings. The median interval from nipple piercing to blood draw was 4.0 (2.0-12.0) years. None of the subjects had hyperprolactinemia. Median (range) prolactin levels for men and women were 5.6 ng/mL (3.8-7.4) and 8.0 ng/mL (2.8-10.9), respectively. Our results suggest that in the absence of any concomitant infection, chronic nipple piercing is not associated with hyperprolactinemia.

    Severe gynecomastia with excessive skin is difficult to treat by only periareolar excision or suction-assisted lipectomy or both. In these patients, total mastectomy and free nipple grafting may be the best option. Placement of the nipple, however, has been arbitrary. With use of 20 "aesthetically perfect" men as models, standard nipple distances were identified. The average sternal notch-to-nipple measurement was 21 cm. In addition, two consistent ratios were identified. The nipple plane was located 0.33 times the distance from the sternal notch to the pubis, and the internipple distance was 0.23 times the chest circumference. With use of preoperatively obtained measurements of the sternal notch to pubis and chest circumference, accurate nipple placement can be accomplished.

    Breast cancer occurring in the mammary gland of men is infrequent. It accounts for 0.8% of all breast cancers, which is less than one per cent of all newly diagnosed male cancers and 0.2% of male cancer deaths. However, Paget disease of the male nipple is extremely rare. We report a single case of Paget disease with infiltrative ductal carcinoma of the breast in a 61-year-old man.

    Gynecomastia is a common deformity encountered by plastic surgeons. The appropriate location of the nipple-areola complex is a major determinant of the aesthetic success of the procedure. To study the natural location of the nipple-areola complex in the normally built male, 50 nonobese men with no evidence of gynecomastia and an average age of 27.9 years were examined. Three ratios were calculated and found to be relatively constant; they were the ratio between the height of the nipple and the height of the patient, the ratio between the distance between the nipples and chest circumference, and the ratio between the suprasternal notch-to-nipple distance and the height of the patient. Using these three parameters, a method of locating the nipple-areola complex on the male chest wall was devised. The method is advocated as a reliable, simple, and useful technique.

    The requirements of the Water Framework Directive suggest the need for further research to test and develop sensitive tools that will allow freshwater managers to detect impacts on fish communities. Diagnostic refinement often encompasses the use of lethal diagnostic tools that are incompatible with the conservation of native ichthyofauna. Here we determine the metal concentration and the pathological response of Squalius laietanus exposed to sewage discharges in the Ripoll river (north-eastern Spain), and compare these findings with our previous studies on Barbus meridionalis using lethal and non-lethal diagnostic tools. Metals concentrations (Zn, Cu, Pb, Hg, Fe, Cd and Ni) were determined in liver and muscle. A complete blood cell profile (haematocrit, haemoglobin, differential leukocyte count, erythrocytic nuclear abnormalities, erythrocytes in division and the development stage of erythrocytes) was used as a non-lethal diagnostic tool to determine early warning signs of disease in these two fish species. As the reference range for these haematological variables is lacking, liver histology, calculation of body condition (CF) and organosomatic indices (HSI and GSI) were employed to support the findings of the blood analyses. Compared to our previous results on B. meridionalis, S. laietanus appeared to have fewer pathological responses than B. meridionalis under the environmental conditions measured and the fish size range examined in this study. Both species showed a similar bioaccumulation pattern, but B. meridionalis stored high Hg and Cu concentrations in muscle and liver, respectively. Hg, Cu and Pb concentrations in fish tissues exceeded the thresholds of European and Spanish legislation. Our findings pinpoint the potential suitability of the blood variables determined in the health diagnoses of these species. Further research will be necessary to establish the natural variability of these and other haematological variables to convert haematology into a

    Nipple adenoma is an uncommon proliferative process of the breast and predominantly occurs in women aged 40-50. Its incidence is extremely low in men, and it has not been reported in a boy. Although nipple adenoma is rare and benign, being familiar with it is important because it clinically resembles Paget disease and histologically adenocarcinoma. We report a case of nipple adenoma in a boy. © 2018 Wiley Periodicals, Inc.

    Objective: To determine the effect of vaginal hygiene module to attitudes and behavior of pathological vaginal discharge prevention in adolescent girls in Sleman Regency, Yogyakarta, Indonesia. Materials and methods: This present study is a quasi experiment with pretest and post-test control group design. A total of 80 female students was selected randomly from two secondary schools at the study site and then distributed equally to control and experimental group. Only participants in the experimental group were given self-learning vaginal hygiene module to maintain vaginal cleanliness. A questionnaire was used as an instrument to measure the attitudes and behavior of vaginal discharge prevention. Paired and independent sample t-tests with significance level (p value) at 0.05 and Confidence Interval (CI) of 95%were employed to compare the mean difference. Results: There is a significant difference in the students' attitude and practice of pathological vaginal discharge prevention between intervention and control group. The students who have been exposed to vaginal hygiene module for six months showed better attitudes and practice in pathological vaginal discharge prevention compared to their counterpart in control group who do not receive any module. Conclusion: The present study implied that vaginal hygiene module can be provided widely for female adolescents at their early puberty. District health officers may work closely with schools' health promoter to reach the students and create a supportive environment for reproductive health discussion and forum in order to achieve better adolescents' reproductive health status.

    Changes in breast sensation after reconstruction are expected. Return of breast sensation after reconstruction and whether nipple-sparing mastectomy offers a substantial benefit in terms of sensation has been inconsistently documented in the literature. We conducted the current study using the pressure-specified sensory device to quantify postoperative breast sensation in patients undergoing nipple-sparing versus non-nipple-sparing mastectomy. Consecutive adult women who underwent nipple-sparing (NSM) and non-NSM (NNSM) and were at least 18 months postreconstruction were included. Breast measurements were taken in 4 quadrants (upper/lower lateral, upper/lower medial) and nipple. Averaged skin cutaneous thresholds [(UL+LL+UM+LM)/4] and nipple sensation between NSM and NNSM were compared as the primary outcome measure. A generalized estimating equations model was used; univariate and multivariate variable analyses were done when appropriate. Forty-four patients (74 breasts) were examined (53 NNSM vs 21 NSM). The groups were further subdivided into autologous versus implant-based reconstruction. Averaged cutaneous skin thresholds for quadrants were better for the NSM, 51.8(±24.5) g/mm versus NNSM, 56.5(±25.7) g/mm, although this difference was not statistically significant. However, NSM breasts measured higher nipple or nipple area sensitivity, 44.5(±30.8) g/mm versus NNSM, 83.8(±27.4) g/mm (P sensation was the number of revision surgeries, especially after third revision. Breast sensation is decreased after reconstruction in both NSM and NNSM, but nipple sensation or nipple area is better preserved in NSM breasts. Number of revision surgeries (>3) was a predictor of decreased sensation.

    Full Text Available Abstract Background The aim of this report was to describe duodenal obstruction caused by a rubber foreign body in a cow. Case Presentation The clinical, biochemical and ultrasonographic findings in a five-year-old Swiss Braunvieh cow with duodenal ileus caused by a calf feeding nipple are described. The main clinical signs were anorexia, ruminal tympany, decreased faecal output and abomasal reflux syndrome. Ultrasonographic examination revealed reticular hyperactivity and a dilated duodenum. A diagnosis of duodenal ileus was made and the cow underwent right-flank laparotomy, which revealed a dilation of the cranial part of the duodenum because of obstruction by a pliable foreign body. This was identified via enterotomy as a calf feeding nipple. The cow was healthy at the time of discharge four days after surgery and went on to complete a successful lactation. Conclusions To our knowledge, this is the first description of duodenal obstruction by a calf feeding nipple. This is an interesting case, which broadens the spectrum of the causes of duodenal ileus, which is usually caused by obstruction of the duodenum by a phytobezoar.

    Full Text Available Nipple areolar reconstruction (NAR has evolved with the advancement in breast reconstruction and can improve self-esteem and, consequently, patient satisfaction. Although a variety of reconstruction techniques have been described in the literature varying from nipple sharing, local flaps to alloplastic and allograft augmentation, over time, loss of nipple projection remains a major problem. Acellular dermal matrices (ADM have revolutionised breast reconstruction more recently. We discuss the use of ADM to act as a base plate and strut to give support to the base and offer nipple bulk and projection in a primary procedure of NAR with a local clover shaped dermal flap in 5 breasts (4 patients. We used 5-point Likert scales (1 = highly unsatisfied, 5 = highly satisfied to assess patient satisfaction. Median age was 46 years (range: 38–55 years. Nipple projection of 8 mm, 7 mm, and 7 mms were achieved in the unilateral cases and 6 mm in the bilateral case over a median 18 month period. All patients reported at least a 4 on the Likert scale. We had no post-operative complications. It seems that nipple areolar reconstruction [NAR] using ADM can achieve nipple projection which is considered aesthetically pleasing for patients.

    Herein we present the results of two related investigations. The first study determined if concentrations in breast nipple discharge (ND) of two proteins (urinary plasminogen activator, uPA and its inhibitor, PAI-1) predicted the presence of breast atypia and cancer in pre- and/or postmenopausal women requiring surgery because of a suspicious breast lesion. The second study assessed if these proteins increased the predictive ability of a carbohydrate (Thomsen Friedenreich, TF) which we previously demonstrated predicted the presence of disease in postmenopausal women requiring surgery. In the first study we prospectively enrolled 79 participants from whom we collected ND, measured uPA and PAI-1 and correlated expression with pathologic findings. In the second study we analyzed 35 (uPA and PAI-1 in 24, uPA in an additional 11) ND samples collected from different participants requiring breast surgery, all of whom also had TF results. uPA expression was higher in pre- and PAI-1 in postmenopausal women with 1) cancer (DCIS or invasive) vs. either no cancer (atypia or benign pathology, p = .018 and .025, respectively), or benign pathology (p = .017 and .033, respectively); and 2) abnormal (atypia or cancer) versus benign pathology (p = .018 and .052, respectively). High uPA and PAI-1 concentrations and age were independent predictors of disease in premenopausal women, with an area under the curve (AUC) of 83-87% when comparing diseased vs. benign pathology. uPA, TF, and age correctly classified 35 pre- and postmenopausal women as having disease or not 84-91% of the time, whereas combining uPA+PAI-1+TF correctly classified 24 women 97-100% of the time. uPA and PAI-1 concentrations in ND were higher in women with atypia and cancer compared to women with benign disease. Combining uPA, PAI-1 and TF in the assessment of women requiring diagnostic breast surgery maximized disease prediction. The assessment of these markers may prove useful in early breast cancer detection

    Adenoma of the nipple is rare in men. It must be distinguished from a breast carcinoma and from Paget disease. In this sense, immunohistochemistry can be of some help. In women, for instance, immunoexpression of c-erbB-2 favors a diagnosis of Paget disease, according to some studies. Nevertheless, we have not found any studies on HER2/neu status, estrogen receptors, or progesterone receptors in nipple adenoma of male patients. We present a case of an adenoma of the nipple in a 21-year-old man in which we carried out a wide immunohistochemical study. The lesion did not express estrogen receptors, progesterone receptors, or androgen receptors. The HercepTest was negative. Smooth muscle Actin and p63 were remarked in the basal layer of the tumoral tubules, supporting the benignancy of the lesion. This case of adenoma of the nipple in a male shows an immunophenotype that is similar to the ones reported in female patients.

    Full Text Available A surgical technique using local tissue skate flaps combined with cylinders made from a naturally derived biomaterial has been used effectively for nipple reconstruction. A retrospective review of patients who underwent nipple reconstruction using this technique was performed. Comorbidities and type of breast reconstruction were collected. Outcome evaluation included complications, surgical revisions, and nipple projection. There were 115 skate flap reconstructions performed in 83 patients between July 2009 and January 2013. Patients ranged from 32 to 73 years old. Average body mass index was 28.0. The most common comorbidities were hypertension (39.8% and smoking (16.9%. After breast reconstruction, 68.7% of the patients underwent chemotherapy and 20.5% underwent radiation. Seventy-one patients had immediate breast reconstruction with expanders and 12 had delayed reconstruction. The only reported complications were extrusions (3.5%. Six nipples (5.2% in 5 patients required surgical revision due to loss of projection; two patients had minor loss of projection but did not require surgical revision. Nipple projection at time of surgery ranged from 6 to 7 mm and average projection at 6 months was 3–5 mm. A surgical technique for nipple reconstruction using a skate flap with a graft material is described. Complications are infrequent and short-term projection measurements are encouraging.

    The surgical approach of gynecomastia, sexual reassignment surgery in female-to-male transsexuals and the increase of number of obese wishing to turn to plastic surgery led us to deepen the anatomical knowledge of the nipple areola complex (NAC) in men, poorly retailed in the literature. By inspiring us of the methodology of a Japanese study, we studied 50 healthy volunteers male, from 18 to 55 years old, from July till August 2015. We measured various distances relative to the NAC to define its vertical and horizontal position, as well as the internipple distance according to the size, to the weight and to the body mass index (BMI). At the end of the analysis, we were able to underline a lower vertical thoracic position of the NAC in the tall category of person, a more side horizontal position to the subject presenting a high BMI and a linear relation between the BMI and the internipple (Em) defined by (Em)=8.96×BMI. The surgeon's judgment and the desires of the patient are essentials basis of therapeutics decisions that could be lean on this anatomical study, which allowed to establish an idea of the cartography of the NAC in man. It will be interesting and necessary to confront it with other studies with larger scale. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  10. Management of flat or inverted nipples with simple rubber bands.

    2011-08-01

    Occurrences of flat or inverted nipples are not uncommon problems, and although they should not preclude breastfeeding, they often seriously hamper initiation and continuation of breastfeeding. Various therapies including nipple exercise, breast shells, inverted syringes, or surgical corrections have been reported with varying success rates. A new method has been devised by the authors that consisted of tying a rubber band around the base of the nipple, with the help of a syringe applicator, to make it prominent. Latex rubber bands cut from condom rims were used in this study. The band had to be worn only during feeding. This method was tested on 19 mothers with flat, inverted, or otherwise deformed nipples. The babies were born in hospitals and were between 9 and 38 days old, mostly fed by bottle feeding, at the time of presentation. The mothers had been counseled about the importance of good attachment during breastfeeding and shown the new method. They were instructed to use the method at home and attend follow-up on day 3, day 7, and day 28. Sixty-three percent of mothers could achieve latching at the breast with good attachment within 3 days, and all did by the end of the month, as nipples no longer remained a problem. The insufficiency of milk was gradually taken care of by frequent suckling with time. No complications like pain or slipping of the band were reported. This simple method may be a good bedside solution for flat/retracted nipples. The authors strongly believe that if the new method is applied immediately after birth under supervision, no mother with nipple problem will be required to feed nonhuman milk to her baby.

    1986-02-01

    The present study was undertaken to review the pathology of florid papillomatosis (FP) of the nipple and to examine the relationship of FP to breast carcinoma. Clinical features of 49 women studied did not differ appreciably from those noted on prior reports, except that in one instance the lesion was probably congenital. Histologically, three distinct growth patterns were found: sclerosing papillomatosis (17 cases), papillomatosis (12 cases), and adenosis (3 cases). In 17 other cases, mixtures of these proliferative patterns were seen. FP with the sclerosing papillomatosis pattern more frequently had areas of focal necrosis in hyperplastic ducts and scattered mitoses, features that might be interpreted as evidence of carcinoma. No prognostic significance can be attributed to these patterns, since all types were cured by excision with follow-up that averaged 8.3 years. Seven of the 49 women had carcinoma in the same breast as FP: Two women had invasive carcinoma that appeared to arise from FP, and four women had concurrent invasive carcinomas that were separate from the FP; the seventh woman developed diffuse intraductal carcinoma 10 years after FP was excised from the same breast. Three of the seven women were also treated for contralateral breast carcinoma. Also reviewed were lesions from two men who had carcinoma arising in FP. One had intraductal carcinoma with Paget's disease and the other had invasive carcinoma. Appreciation of the diverse histological patterns of FP may be helpful in avoiding an erroneous diagnosis of carcinoma. Features indicative of carcinoma arising in FP are Paget's disease and areas of invasion. FP of the nipple is rarely the substrate for mammary carcinoma and is adequately treated by local excision. Coexistence with carcinoma elsewhere in the same or opposite breast occurs often enough to warrant thorough examination of the breasts when FP of the nipple is diagnosed. The risk of subsequent carcinoma following excision of FP appears to

    Gynecomastia is a common disorder observed in male plastic surgery patients. Treatment options may include observation, surgical excision, or liposuction techniques. Congenital herniated nipple is a more rare condition, especially in male patients. We present the case of a 12-year-old boy with bilateral gynecomastia and herniated nipple-areolar complexes. A staged repair was undertaken in this patient with grade 2 gynecomastia. The first operation was ultrasonic liposuction bilaterally, yielding 200 mL of aspirate from the left and 400 mL on the right, to correct the gynecomastia. The second procedure, performed 6 months later, was a bilateral periareolar mastopexy to repair the herniated nipple-areolar complexes. The result of the first procedure was flattened and symmetrical breast tissue bilaterally, essentially a correction of the gynecomastia. The herniated nipples were still present, however. Bilateral periareolar mastopexies were then performed with resulting reduction of the herniations. There were no complications with either procedure, and a good cosmetic result was achieved. A staged surgical approach was successful in correcting both conditions with an excellent aesthetic result and the advantage of decreased risk for nipple complications.

    The authors present a man who underwent chest augmentation and nipple piercing. The patient developed chronic nipple infection, which led to unnecessary invasive diagnostic procedures, serious implant infection, and eventually urgent explantation. This unfavorable scenario illustrates the distinct features of the procedure in men, which includes close proximity of the nipple to the implant and reduced awareness by health care providers. Based on this case the authors recommend avoiding nipple piercing in men with chest implants.

  14. "Seeing Is Believing": Dermatoscope Facilitated Breast Examination of the Breastfeeding Woman with Nipple Pain.

    It is well recognized that breastmilk provides optimal nutrition and immunological protection for infants. Many women, however, experience nipple pain while breastfeeding, leading to premature cessation of nursing. To overcome these difficulties, timely diagnosis is crucial to effectively treat the underlying pathology and permit resumption of breastfeeding. Examination of the superficial breast plays a key role in accurate diagnosis. Traditional direct inspection is clearly inadequate for this task. The dermatoscope is a useful tool, enlarging and illuminating an area of epidermis to obtain an optimal image. Improvements in dermoscopy involving polarization obviate the need for full contact with the examined surface, thereby providing anatomical detail in three dimensions. A novel practice presented in this article features clinical cases introducing this technique as it is applied to the lactating breast, conclusively distinguishing normal from abnormal and illustrating the efficacy and added diagnostic value of this approach. The dermoscope is shown to facilitate identification of the causes of nipple pain ranging from asymptomatic candidal infection to exquisitely painful, minute traumatic erosions, aiding, thereby, in diagnosis of the underlying causes of nursing difficulties. Improved wound surveillance and standardization for purposes of research documentation are additional benefits anticipated with the use of breast dermoscopy. We conclude that real-time, high-quality, magnified imaging of the lactating breast represents a recognizable advance in pursuit of a rapid and accurate technique that aids in the identification of the factors responsible for lesions affecting nursing women. Moreover, it features an already existing technology requiring little training at a reasonable cost.

    We describe a new wound management technique using a soft dressing material to stabilize the areola skin graft and protect the nipple after nipple-areola reconstruction at the final stage of breast reconstruction. We introduced a center-fenestrated multilayered hydrocellular polyurethane foam dressing material that provides adequate pressure and retains a moist environment for a smooth skin graft "take." Moreover, the reconstructed nipple can be monitored at any time through the fenestrated window for adequate blood circulation. Altogether, this simple and inexpensive wound dressing technique improves the clinical outcome. Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

    Correlation of information from multiple-view mammograms (e.g., MLO and CC views, bilateral views, or current and prior mammograms) can improve the performance of breast cancer diagnosis by radiologists or by computer. The nipple is a reliable and stable landmark on mammograms for the registration of multiple mammograms. However, accurate identification of nipple location on mammograms is challenging because of the variations in image quality and in the nipple projections, resulting in some nipples being nearly invisible on the mammograms. In this study, we developed a computerized method to automatically identify the nipple location on digitized mammograms. First, the breast boundary was obtained using a gradient-based boundary tracking algorithm, and then the gray level profiles along the inside and outside of the boundary were identified. A geometric convergence analysis was used to limit the nipple search to a region of the breast boundary. A two-stage nipple detection method was developed to identify the nipple location using the gray level information around the nipple, the geometric characteristics of nipple shapes, and the texture features of glandular tissue or ducts which converge toward the nipple. At the first stage, a rule-based method was designed to identify the nipple location by detecting significant changes of intensity along the gray level profiles inside and outside the breast boundary and the changes in the boundary direction. At the second stage, a texture orientation-field analysis was developed to estimate the nipple location based on the convergence of the texture pattern of glandular tissue or ducts towards the nipple. The nipple location was finally determined from the detected nipple candidates by a rule-based confidence analysis. In this study, 377 and 367 randomly selected digitized mammograms were used for training and testing the nipple detection algorithm, respectively. Two experienced radiologists identified the nipple locations

    Basal cell carcinoma (BCC) of the nipple-areola complex is uncommon. It has been suggested that BCCs in this region behave more aggressively, with a higher potential for distant spread, than in other anatomical sites. To address questions about etiology, behavior, optimal treatment, and prognosis of this entity. A literature search identifying all cases of BCC of the nipple and nipple-areola complex in the English literature from 1893 to 2008. Thirty-four cases of BCC of the nipple, areola, or both were identified, mostly affecting middle-aged men. The majority of patients were treated with tissue-sparing surgery. There was a metastatic rate of 9.1%, and one patient died from the disease (3.0%). The optimal treatment of this condition should be local excision, but patients with this condition should be followed up for primary site recurrence and axillary metastasis, because there is greater incidence than with BCC at other anatomical sites. Furthermore, proven axillary metastasis should be surgically treated.

    Although basal cell carcinoma is extremely common, it only rarely occurs on the nipple. Men are affected more often than women. Basal cell carcinoma of the nipple-areola complex may be more aggressive as metastases to regional lymph nodes have been reported.

    In planning gender-reassignment surgery for biological women and treating men with gynecomastia, surgeons must have a thorough understanding of anatomically correct nipple positions and appropriate areola sizes in men. The authors sought to determine whether body height or body mass index (BMI) affects nipple position or areola size in men. Anatomic measurements of the nipples and areolae of 50 Japanese men were obtained. A relative coordinate system was defined, where the medial-lateral and superior-inferior positions of the nipple were quantitatively indicated by distance ratios between anatomic landmarks. Nipple positions were evaluated for each patient by referring to this coordinate system, and the positions were compared between groups categorized by body height or BMI. Nipple position was not significantly affected by body height. However, the nipple tended to be located more laterally in participants with higher BMI. The vertical nipple position differed between standing and supine positions. Tall men had larger areolae than short men; however, areola size did not differ with respect to BMI. Nipple position and areola size vary by body shape. Consideration of the differences is recommended when performing procedures such as female-to-male gender-reassignment surgery or correction of gynecomastia. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    The purpose of this study was to describe the mammographic and sonographic appearances and the clinical-pathologic features of invasive micropapillary carcinoma. Between December 1999 and March 2005, among the 3,109 patients who underwent operation for breast cancer, 25 patients proved to have invasive micropaillary carcinoma. Among the 25 patients, we included 22 patients (mean age: 48, range: 26-77 years) who had undergone preoperative mammography and ultrasound. The mammographic and sonographic findings of the lesions were analyzed retrospectively. The pathologic findings were analyzed via the clinical records and pathology reports. Patients manifested with a palpable mass (77%, 17/22), bloody nipple discharge (14%, 3/22) or incidental lesion on the screening mammography (9%, 2/22). On mammography, a mass with an irregular (86%, 12/14) shape and an indistinct (43%, 6/14) or spiculated (43%, 6/14) margin was the most common findings on mammography. On sonography, a hypoechoic (91%, 20/22) mass with irregular shape (73%, 16/22) and an indistinct (32%, 7/22) or microlobulated (32%, 7/22) margin was the most common findings. Pathologically, axillary lymph node metastasis was present in 73% (16/22) of the patients. Invasive micropapillary carcinoma appeared an irregular shaped mass with an indistinct margin mass or microcalcifications on mammography and/or sonography. The tumors were frequently associated with axillary lymph node metastasis

    We retrospectively analysed mammographies of 909 ductal carcinoma in situ (DCIS) (1980-1999) and compared our results to those of literature. Microcalcifications were present in 75% of the cases, and soft-tissue abnormalities in 27% cases with association with calcifications in 14% of cases. Palpable masses were found in 12% of the cases and nipple discharge was present in 12% of the cases. The radiographic-pathologic correlation allowed to suspect the DCIS ''aggressiveness'' on radiologic signs. Granular, linear, branching and/or galactophoric topography of the microcalcifications were correlated with necrosis, grade 3, comedocarcinoma type. A number of microcalcifications higher than 20 was correlated with necrosis and grade 3. Mammographic size was correlated to histologic size. Masses were correlated with grade 1. A diagnosis strategy can be proposed with a multidisciplinar approach

    Patients undergoing nipple-sparing mastectomy and immediate-implant based reconstruction occasionally require a mastopexy based on their breast size and degree of ptosis. Previous reports have shown the feasibility of mastopexy-nipple-sparing mastectomy in selected patients to raise the nipple up to 5 cm. Major mastopexy with nipple transposition more than 6 cm in conjunction with nipple-sparing mastectomy for therapeutic indications has not been described. The authors review their experience with primary buttonhole mastopexy performed in conjunction with nipple-sparing mastectomy. Between 2008 and 2014, 16 patients (32 breasts) underwent bilateral primary mastopexy and nipple-sparing mastectomy with immediate staged implant-based reconstruction. The Passot buttonhole technique was used for the mastopexy in all patients, raising the nipple from 7 to 12 cm. Tumor-related data, risk factors, breast size, degree of ptosis, expander size, fill volume, selection criteria, and complications are discussed. The average follow-up period was 33 months (range, 14 to 80 months). There were no tumor recurrences, and all patients completed their reconstruction. Two patients required removal of the expander and delayed reconstruction because of infection and implant exposure due to nipple-areola loss. The reasons for nipple-areola loss and technical modifications to enhance skin viability by retaining a thin layer of subareolar breast tissue for removal during the second-stage implant exchange are discussed. Primary mastopexy using the buttonhole technique performed together with nipple-sparing mastectomy is a safe procedure with predictable results in patients with very large or ptotic breasts requiring lifts greater than 6 cm. The success of the combined procedure depends on preserving a thin layer of subareolar breast tissue and removing it at the time of implant exchange.

    The role of nipple/breast stimulation in influencing sexual arousal in men and women during lovemaking has only been the subject of opinion-based comment rather than evidence-based study. No attempt to question people about such sexual behavior has ever been undertaken. The study was designed to ascertain the effects of nipple/breast manipulation in young men and women on their sexual arousal. A short questionnaire about nipple/breast stimulation during sexual activity was administered to 301 (148 men; 153 women) sexually experienced undergraduates (age range 17-29 years, 95% between 18 and 22). Replies to questions in questionnaire. The major findings in regard to the women were that 81.5% reported that stimulation of their nipples/breasts caused or enhanced their sexual arousal, 78.2% agreed that when sexually aroused such manipulation increased their arousal, 59.1% had asked to have their nipples stimulated during lovemaking, and only 7.2% found that the manipulation decreased their arousal. In regard to the men, 51.7% reported that nipple stimulation caused or enhanced their sexual arousal, 39% agreed that when sexually aroused such manipulation increased their arousal, only 17.1% had asked to have their nipples stimulated, and only 7.5% found that such stimulation decreased their arousal. Manipulation of the nipples/breasts causes or enhances sexual arousal in approximately 82% of young women and 52% of young men with only 7-8% reporting that it decreased their arousal.

    Breast conserving surgery has been a recognised method of treatment of early breast cancer. The treatment methods include quadrantectomy or skin sparing mastectomy combined with ipsilateral axillary nodal dissection followed by radiotherapy. In the current study we evaluate the feasibility and oncologic safety of the quadrantectomy and SSM operations with preservation of the nipple and areola, and the cosmetic results of immediate reconstruction by using the latissmus dorsi flap. Materials and Methods: A breast conservative surgery (quadrantectomy or nipple sparing mastectomy) was carried out in a group of 55 patients with invasive breast cancer treated at the Department of Surgical Oncology, NCl, between January 2001 and April 2004. The selection criteria included those patients who presented with TI or T2 breast cancer and were located at least 2 cm from the nipple as the centre for the nipple areola complex. The age of the patients ranged from 32 years to 65 years. The follow up period ranged from 2 to 33 months with an average of 21 months. Pathological assessment of the specimens showed a negative safety margin in all cases. Most of our cases were invasive duct carcinoma grade 1-2 (42) (75%). The complications of the flap reconstruction included one major sloughing of the Iatissmus dorsi flap, 4 partial flap sloughing, 4 sloughing of the nipple and fat necrosis in 6 patients. The donor site healed normally in all of our cases except for one patient who suffered from a hypertrophic scar which settled down during the follow up period. The aesthetic assessment of the patients, showed an excellent to good results in the majority of cases (42) (75%) while in 6 (12%) results were fair and in 7 (13%) results were poor. Breast conservative surgery with quadrantectomy or skin sparing technique with preservation of the nipple and areola combined with immediate LD flap reconstruction is a valid procedure for treatment of early breast cancer.

    Benign circumscribed cutaneous lymphadenosis of the areola of the nipple (Bäfverstedt's disease) occurs in children and adults. We observed 11 cases: 3 men, 3 children and 6 women. The areola undergoes rapid swelling and becomes red. At times the nipple itself is included. Unilateral enlargment and distortion of the nipple area becomes apparent. Sometimes this is associated with a tumor-like infiltration of the retro-mammillary tissue. In Contradistinction to Pagets disease of the nipple and to a mammillary adenoma there is no eczema and no ulceration. The clinical features and the typical pruritic course establish the diagnosis. Healing is spontaneous, but protracted. The aetiology is probably of an inflammatory nature. Treatment with short courses of antibiotics and anti-inflammatory agents resulted in a faster reduction of the cutaneous signs and corroborated the clinical diagnosis. We consider surgical treatment as unnecessary because circumscript benign lymphadenosis of the nipple area has a harmless course.

    2017-01-01

    Background: Nipple–areolar reconstruction is the final step in breast reconstruction. Reconstruction using local flaps and tattooing is useful in cases of bilateral reconstruction, a small nipple–areolar complex (NAC) as the donor site, and avoiding disturbance of the normal side and other body parts. However, this method can cause projection loss and color fading of the nipple. Moreover, the breast mound is reconstructed with an implant. Methods: We performed nipple–areolar reconstruction of 90 nipples using clover-designed flaps oriented at 120 degrees and tattooing after breast silicone implantation in 64 women. The tattoo was designed before flap operation and stained darker. Following donor site closure, a dermal flap was made as a bridge for nipple support. The nipple space was separated by the dermal flap from the breast mound and was filled with subcutaneous tissue. The size of the reconstructed nipple projection was measured postoperatively and 1 year later. The projection maintenance rate was calculated. Results: The heights of the nipple projection were 11.3 ± 1.8 mm (95% confidence interval [CI]: 10.9–11.7) just after the operation and 6.09 ± 2.4 mm (95% CI: 5.6–6.6) 1 year later. The actual range of nipple projection between these 2 heights was 5.2 ± 2.4 mm (95% CI: 4.7–5.7). The maintenance rate of the reconstructed nipple projection after 12 months was 54.1 ± 20.9 (95% CI: 49.7–58.5). The nipple color was maintained for over a year. Conclusions: Our nipple–areolar reconstruction technique could maintain the projection and color of the reconstructed nipple for a long period. Good outcomes were obtained in this implant-based breast reconstruction. PMID:28507843

    2008-05-01

    Dual pathology is defined as the association of two potentially epileptogenic lesions, hippocampal (sclerosis, neuronal loss) and extrahippocampal (temporal or extratemporal). Epileptic activity may be generated by either lesion and the relative importance of every lesion's epileptogenicity conditions the surgical strategy adopted. Most frequently associated with hippocampal sclerosis are cortical dysplasias. The common physiopathology of the two lesions is not clearly established. Extrahippocampal lesions may be undetectable on MRI (microdysgenesis, for example) and ictal discharge patterns may vary among dual pathology patients. The surgical strategy depends on the location of the extrahippocampal lesion and its relative role in seizure generation; however, reported surgical results suggest that simultaneous resection of mesial temporal structures along with the extrahippocampal lesion should be performed.

    Full Text Available Blood spurting or oozing from a varix confirms the diagnosis of variceal hemorrhage. In most cases of variceal hemorrhage, however, the bleeding has ceased by the time endoscopy is performed. Endoscopists rely on identification of stigmata of recent hemorrhage to determine whether varices are the cause of bleeding and to predict the likelihood of rebleeding. Most of the attention has focused on red color signs, such as red wale markings, described by Beppu et al. [Gastrointest Endosc 1981;27:213–218] and well known to endoscopists. Here we describe our experience with a less recognized stigma of variceal hemorrhage known as the ‘white nipple sign’, which resulted in active hemorrhage when manipulated.

    A 25-year-old woman presented to our dermatology unit with progressive diffuse thickening of the both areolas. A skin biopsy was taken from the right areola showing irregular filiform acanthosis with elongation and anastomosis of rete ridges, irregular orthokeratotic hyperkeratosis, pseudocyst formation, and hyperpigmentation of the basal layer. The cause of nevoid hyperkeratosis of the nipple and areola is unknown. Eighty percent of cases occur in women and are often manifested during puberty or pregnancy. The disease may also occur in men receiving hormonal therapy. There is no uniformly effective treatment. Dermatologists, gynecologists, and general practitioners have an important part to play in recognizing this condition that may be underdiagnosed because of lack of awareness.

    Numerous techniques have been used in an attempt to achieve long-term nipple projection following nipple-areolar reconstruction (NAR). A common setback, however, is the diminution of projection over time; this phenomenon is particularly evident following implant based breast reconstruction. The purpose of this report was thus to evaluate surgical outcomes and long-term nipple projection with the use of "modified skate flap" technique in exclusively implant based postmastectomy reconstructions. A retrospective review was performed for the period between 1993 and 2007. All consecutive patients with 2-staged tissue expander/implant reconstructions followed by NAR using the modified skate flap technique performed by the senior author (P.C.) were identified in a prospectively maintained breast reconstruction database. Only patients with a minimum of 1-year follow-up were included in the study. Patients with a history of irradiation to the breast were excluded from nipple projection assessment. Clinical outcome measurements included long-term nipple projection as well as incidence of complications from the NAR procedure using the modified skate flap technique. Over the 15-year study period, 475 patients underwent 2-staged tissue expander/implant reconstruction followed by NAR using the modified skate flap technique. Of these, there was a total of 292 patients with the minimum requirement of 1-year follow-up post NAR (61% follow-up rate). The total number of reconstructed nipple areolar complexes evaluated in this series was 422 (130 bilateral and 162 unilateral NAR). Forty patients (28 unilateral and 12 bilateral NAR) who received radiation to their breasts were excluded from nipple projection assessment. At a median follow-up of 44 months (range: 12-84 months), mean nipple projection was 2.5 mm (range: 1-4 mm). Minor complications occurred in 7.2% of the patients (n = 292). Skin graft donor site dehiscence was the most common complication (3.1%) followed by partial skin

    Full Text Available Abstract Background Previous studies have reported that the design of the water dispensers can influence the water intake in farm animals. Horses and dairy cows seem to prefer to drink from an open surface whereas sheep and pigs apparently prefer water nipples, probably because of the worse water quality in water bowls. The aim of the present study was to examine the preference of dairy goats for water nipples or water bowls. Methods In each of the two experiments (exp. 1, dry goats, exp. 2 lactating goats, 42 dairy goats were allotted into 6 groups of 7 goats. In period 1, the goats had access to a water nipple. In period 2, they had access to a water bowl and in period 3 (preference test they had access to both a water nipple and a water bowl. Water usage and wastage was recorded and water intake (water usage - water wastage was calculated for each group for the two last days of each period. In experiment 2, water samples from each dispenser were analyzed for heterotrophy germs at 22°C, Escherichia coli and turbidity. Results Water usage was higher from water nipples than from water bowls both in experiment 1 (dry goats and experiment 2 (lactating goats. There was however, no difference in water intake from water nipples and water bowls. In the preference test (period 3, the water intake tended to be higher from the water nipple than from the water bowl both for the dry goats (exp. 1 and lactating goats (exp. 2. Especially for the dry goats, the differences between groups were large. Turbidity and heterotrophy germs were much higher in the samples from the water bowls than from the water nipples. Water wastage from the water bowls was negligible compared to the water nipples. From the water nipples the water wastage was 30% and 23% of water usage for the dry and lactating goats respectively. Conclusions We conclude that type of water dispenser (nipple or bowl was probably of minor importance for water intake in goats, but water bowls had a

    The causes of bilateral absence of the nipple-areola complex in men are seldom congenital, but attributable rather to destruction as a result of trauma, or after mastectomy in female-to-male transsexuals and in male breast cancer, or after the correction of extreme bilateral gynecomastia. Such a bilateral loss becomes a major reconstructive challenge with respect to the configuration and localization of a new nipple-areola complex. Because there is very little information available in the literature, we carried out a cross-sectional study on the configuration and localization of the nipple-areola complex in men.A total of 100 healthy men aged 20 to 36 years were examined under standardized conditions. The first part of the study dealt with the configuration of the nipple-areola complex (dimensions, round or oval shape). The second part concentrated on the localization of the complex on the thoracic wall with respect to anatomic landmarks and in correlation to various parameters such as weight and height of the body, circumference of the thorax, length of sternum, and position in the intercostal space. Of the 100 subjects examined, 91 had oval and seven had a round nipple-areola complex. An asymmetry between the right and the left side was found in two cases. The mean ratio of the horizontal/vertical diameter of an oval nipple-areola complex was 27:20 mm and the mean diameter for a round nipple-areola complex was 23 mm. The center of the nipple-areola complex was in the fourth intercostal space in 75 percent and in the fifth intercostal space in 23 percent of the subjects. To localize the nipple-areola complex on the thoracic wall de novo, at least two reproducible measurements proved to be necessary, composed of a horizontal line (distance from the midsternal line to the nipple = A) and a vertical line (distance from the sternal notch to the intersection of line A, = B). The closest correlation for the horizontal distance A was given by the circumference of the

    Full Text Available BackgroundGynecomastia is benign enlargement of breast tissue in males and is fairly common. Mastectomy not only helps in improving the shape of anterior chest, but can also improve the location of nipple. Therefore, a principle element of mastectomy design is defining the normal location of nipple based on major anatomical reference points. Here, the nipple location was compared for before and after gynecomastia surgery. In addition, the same was also compared between male patients undergoing gynecomastia surgery and control group of subjects without gynecomastia.MethodsWe retrospectively analyzed gynecomastia patients who underwent conventional subcutaneous mastectomy. Preoperative and postoperative anatomical landmark distances and chest circumferences were measured and compared to the same anthropometric data from 20 healthy adult male controls.ResultsNipple locations were compared among 13 patients and 20 controls. The mean weight of resected breast tissue was 246 g, and overall patient satisfaction grade was 4.3 out of 5. In the patient group, the slopes for the height-distance from the sternal notch to the nipple and chest circumference-distance between the mid-line of the sternum and the nipple were 0.175 and 0.125 postoperatively, respectively. The slopes of the control group were 0.122 and 0.177, respectively; these differences were statistically significant (P<0.05.ConclusionsNipple positions were considerably lower in patients with gynecomastia than in control subjects. Subcutaneous mastectomy was associated with mild elevations, but postoperative locations were still lower compared to controls. Further efforts are needed to improve the location of postoperative nipple-areola complex in patients with gynecomastia.

  20. Mesostructure of Ordered Corneal Nano-nipple Arrays: The Role of 5-7 Coordination Defects

    2016-06-01

    Corneal nano-nipple structures consisting of hexagonally arranged protrusions with diameters around 200 nm have long been known for their antireflection capability and have served as biological blueprint for solar cell, optical lens and other surface designs. However, little is known about the global arrangement of these nipples on the ommatidial surface and their growth during the eye development. This study provides new insights based on the analysis of nano-nipple arrangements on the mesoscale across entire ommatidia, which has never been done before. The most important feature in the nipple structures are topological 5- and 7-fold coordination defects, which align to form dislocations and interconnected networks of grain boundaries that divide the ommatidia into crystalline domains in different orientations. Furthermore, the domain size distribution might be log-normal, and the domains demonstrate no preference in crystal orientation. Both observations suggest that the nipple growth process may be similar to the nucleation and growth mechanisms during the formation of other crystal structures. Our results are also consistent with the most recently proposed Turing-type reaction-diffusion process. In fact, we were able to produce the key structural characteristics of the nipple arrangements using Turing analysis from the nucleation to the final structure development.

  1. A Supernumerary Nipple-Like Clinical Presentation of Lymphangioma Circumscriptum.

    Lymphangioma circumscriptum is a superficially localized variant of lymphangioma. The characteristic clinical presentation is a "frogspawn" grouping of vesicles or papulovesicles on the proximal limb or limb girdle areas. Though most lymphangiomas develop congenitally, the lymphangioma circumscriptum subtype is known to present in adults. We report a case of lymphangioma circumscriptum on the left inframammary area of an African American female with an unusual supernumerary nipple-like clinical presentation. Our patient presented with a firm, smooth, hypopigmented papule, and the clinical diagnosis of keloid was made initially. However, she returned reporting growth of the lesion and was noted to have a firm, exophytic, lobulated, pink to skin-colored nodule. Histopathological examination demonstrated dilated lymphatic vessels, consistent with the diagnosis of lymphangioma. The presentation as a firm, hypopigmented papule and later exophytic, lobulated, skin-colored nodule in our case represents a clinical presentation of lymphangioma circumscriptum not previously described in the literature. Correct diagnosis in lymphangioma circumscriptum is vital, as recurrence following surgical resection and secondary development of lymphangiosarcoma and squamous cell carcinoma following treatment with radiation have been reported. Thus, it is important to consider lymphangioma circumscriptum in the differential of similar lesions in the future to allow appropriate diagnosis, treatment, and monitoring.

    Body piercing has become increasingly prevalent. We describe a case of breast infection with combined mycobacteria and anaerobe following nipple piercing, and review the literature. A 17-year-old female developed a breast abscess 4 months after nipple piercing. Cultures grew Prevotalla melangenica and Mycobacterium fortuitum. She required drainage and antibiotic treatment. Three months into her treatment she stopped her medications, relapsed, and required drainage. Two months later, on antimycobacteria therapy, her wound is healing. Review of the infectious complications of nipple piercing yielded 12 cases, 5 of which had a foreign body. The pathogens isolated (coagulase negative staphylococcus, mycobacteria, streptococcus, anaerobe, and gordonia) are not the usual organisms to be isolated from a breast abscess. This could result from reporting bias or the presence of a foreign body, the nipple ring. The three cases of mycobacteria, in addition to ours, are reviewed. The average age is 22 years. Three to 9 months elapsed between piercing and infection. All cases required drainage. Antimycobacteria therapy was used in three of the four cases for 10 days to 6 months. With the increasing prevalence of body piercing, it is important to document and report infections. We describe a breast abscess following nipple piercing with combined anaerobic and a mycobacterial pathogens. This underscores the need for obtaining cultures including anaerobes and mycobacteria.

    Nipple-sparing mastectomy is gaining widespread popularity, as it could allow improved aesthetic outcome without increasing oncologic risk. To investigate the reconstructive issues experienced with immediate implant reconstruction, the authors reviewed the cosmetic outcomes of their series. The authors retrospectively analyzed the data on 33 cases of nipple-sparing mastectomy for both cancer and prophylaxis with immediate implant reconstruction using the submusculo-subfascial pocket. Cosmetic evaluation methods were clinical and photography-based assessments and a patient-satisfaction survey. The average follow-up period was 26.8 months. No nipple-areola complex cancer involvement was registered. The reconstructive outcomes ranged from good to excellent in 83 percent of the cases. Patients' satisfaction was high to very high, except in one patient who experienced total nipple-areola complex loss (one breast, 2.4 percent). Overall, early minor complications were registered in four breasts (9.5 percent) and late minor complications in five cases (12 percent). The authors' series suggest that nipple-sparing mastectomy is an option for carefully selected and screened patients. Larger studies with longer follow-up are needed, however. On the whole, the immediate one-stage implant reconstruction with hyperprojected anatomical gel implants represents a valid option. The skin incision algorithm proposed, which is based on the breast size, shape, and previous scars, might aid in the decision-making process to achieve satisfying results using this procedure. The radial approaches represent a good compromise between the oncologic and reconstructive procedures.

    Nipple piercing gains popularity and social acceptance within the last years, especially among young people. The medical literature reports an increase of complications in the post-piercing period. We report a case of a young woman, who presented with a light enlargement of the right breast and tenderness in the retroareolar region following nipple piercing 5 months ago. On ultrasound, a poorly marginated hypoechoic lesion was seen which was suspicious of an inflammation. After 1 week of antibiotic therapy, the mass had enlarged. As carcinoma could not be excluded, open biopsy was performed. Histology showed signs of chronic mastitis. To date, only a few reports of breast abscess after nipple piercing have been published. With the increasing prevalence of body piercing, it is important to document and report infections which may be discovered many months following piercing. Carcinoma can mimic breast abscess and should be included in the differential diagnosis.

    Pigmented Paget disease of the nipple is a rare disease. We report on a 60-year-old woman in whom this diagnosis was made based on clinical findings, dermoscopy, histology and immunohistology. Circumscribed pigmentation of the nipple includes a wide spectrum of benign and malignant differential diagnostic considerations. Dermoscopy can enhance the clinical diagnosis. Biopsies should always be performed on unclear pigmentation of the nipple in both women and men. On histology, rare melanocytic tumors must be differentiated from pigmented Paget disease and pigmented Bowen disease. Pagetoid intraepithelial cells of a melanocytic tumor are positive for S100, HMB45 or melan A, but not for cytokeratins. Intraepithelial tumor cells of Paget disease are positive for cytokeratin 7. The clear cells in Bowen diseases are usually not positive for cytokeratin 7 and are also negative for all melanocytic markers.

    Basal cell carcinoma (BCC) of the nipple-areola complex is very rare. Only 24 cases were reported in the literature and 17 (70.8%) of these cases arose in men. Most of the cases were treated with simple excision. We report on a case of BCC of the nipple-areola complex in a 46-year-old woman, treated with partial mastectomy. Metastasis to the axillary lymph nodes had been noted in 3 (12.5%) of the 24 reported cases of BCC of the nipple-areola complex. Thus, we applied the concept of the sentinel lymph node to detect possible metastases of axillary lymph nodes, letting us avoid the unnecessary axillary lymph node dissection and possible future morbidity.

    Two white men 57 and 39 years old, and a 47-year-old white woman were seen with slowly developing papulo-nodular lesions of the areola-nipple complex. None of the patients presented with regional lymphadenopathy, history of trauma, or relevant sun-exposure. After excison of the mass, the histologic diagnosis of basal cell carcinoma was made. At two years of follow-up, no recurrence was evident. The low incidence of basal cell carcinoma in this particular site allows us to consider the areola-nipple complex location as unusual. Moreover, literature reports do not suggest that these BCCs have an increased potential for malignancy. The treatment options depend on the extension of the tumor and on the possible involvement of the areola-nipple complex and mammary tissue.

    Full Text Available Preservation and prolongation of the lactation period is not only a guarantee of the child's full physical and mental development but also one of the most important methods for reducing the risk of developing breast cancer. Problems with the mammary gland nipple in a woman in the early postnatal period lead to a refusal of lactation. We carried out a retrospective analysis (period from 2010 to 2016 of the causes of traumatizing mammary gland nipples in the early postnatal period in 172 women (mean age 29.1 ± 4.3 years. Methods of prevention and treatment of nipple injuries in the early postnatal period have been offered for the lactation period prolongation.

    To construct an immunocompetent nipple valve anastomosis (NVA) to exclude faecal reflux and compare it with an end-to-end anastomosis to see if it would prevent recurrent inflammation caused by intraluminal bacterial antigens in Crohn's disease. Laboratory study. Teaching hospital, Germany. Two groups of six beagle dogs each of which had NVA or end-to-end anastomosis. Construction of a NVA by stapling the telescoped nipple, and replacing the ileal mucosa on the valve by colonic mucosa; end-to-end anastomosis. Radiological, bacteriological, angiographic, and morphometric results. Absolute retrograde pressure-competence and free orthograde permeability of the NVA resulted in significantly lower intestinal bacterial counts compared with the end-to-end anastomosis (p < 0.05). Transposition of colonic mucosa was successful as demonstrated by revascularisation from the ileal nipple and looked normal on morphometry. If NVA were constructed in patients with Crohn's disease, recurrences should be prevented, which would verify the immunopathogenetic hypothesis of new inflammation.

    Background. The aim of this study was to describe the clinical, mammographical and pathological characteristics of inflammatory carcinoma. Patients and methods. Clinical, mammographical and histological sections of twenty-two women (age range 28-60 years) were reviewed. The examinations had been performed over a period of four years. Results. The clinical findings were: erythema, edema, thickening of the skin and breast heat in ten patients; palpable mass in nine patients; nipple discharge in one patient; absent in two patients. Pathological findings were: tumor emboli in the dermal lymphatics in eight patients; tumor emboli in the vessels in ten patients; tumor emboli both in the dermal lymphatics and in the vessels in four patients. The radiologic findings were: skin thickening, trabecular thickening and blurring of structure in ten patients (common presentation); mass in nine patients; malignant-type calcifications in two patients (uncommon presentation); absent in one patient. The follow-up examination (eighteen months) detected that only one patient with common presentation of inflammatory carcinoma had no local or systemic recurrence against eight patients with uncommon presentation. Conclusions. The clinical and mammographical aspects, which suggest the presence of an inflammatory carcinoma, occur only in 45.4% of the patients. The radiological aspect seems to correlate with the different prognosis of the tumour, resulting in a better prognosis in those with an uncommon aspect. (author)

    Gynecomastia, as a most common benign condition, represents itself as the enlargement of the male breast and also nipple-areola complex as the severity of the condition increases. With this study, we aimed to clarify the effects of 980-nm diode laser on nipple-areola complex (NAC). Although numerous open techniques have been described to correct gynecomastia, nowadays trends have shifted to minimally invasive techniques such as laser-assisted lipolysis (LAL). A total of 25 patients with bilateral gynecomastia treated with LAL by using a 980-nm diode laser. The resultant contour and reduced size of the complex were satisfactory. LAL leads to significant reduction of the size of NAC.

    Context We define the scope and needs within the new discipline of computational pathology, a discipline critical to the future of both the practice of pathology and, more broadly, medical practice in general. Objective To define the scope and needs of computational pathology. Data Sources A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. Conclusions The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and non-pathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology. PMID:26098131

    Contrast-enhanced MR imaging of the breast has been found to be valuable in the assessment of local recurrence of previously treated breast cancer. We looked specifically at the appearances of the skin and nipple of the treated breast in order to describe the appearances of post-treatment change and recurrence in this region. Thirty-nine women treated for breast cancer had MR imaging of one or both breasts reviewed retrospectively with particular attention to the nipple and skin. The skin and chest wall were assessed for patients with mastectomies. All available histology of the skin and/or nipple, obtained following MR imaging, was reviewed. In patients who did not undergo surgery following MR imaging, clinical follow-up was obtained. Six of 39 cases had nodular enhancing areas seen on MR imaging, which correlated with histology demonstrating tumour recurrence within the skin and/or nipple. Of the remaining 33 patients, changes of linear or diffuse enhancement were seen in the skin and/or nipple of 15 patients. These changes were shown to be benign post-treatment changes at surgery/biopsy in 4 cases or by clinical follow-up in the remainder. In this article we demonstrate differing patterns of contrast enhancement within the skin and nipple in recurrent breast carcinoma vs post-treatment changes. This suggests that contrast-enhanced MR imaging of the breast may be a useful tool in differentiating tumour recurrence from post-treatment changes within the skin and nipple. (orig.)

    An inverted nipple is a common congenital condition in young women that may cause breastfeeding difficulty, psychological distress, repeated inflammation, and loss of sensation. Various surgical techniques have been reported for correction of inverted nipples, and all have advantages and disadvantages. Here, we report a new technique for correction of an inverted nipple using an operative microscope and traction that results in low recurrence and preserves lactation function and sensation. Between January 2010 and January 2013, we treated eight inverted nipples in seven patients with selective lactiferous duct dissection using an operative microscope. An opposite Z-plasty was added at the junction of the nipple and areola. Postoperatively, traction was applied through an apparatus made from a rubber gasket attached to a sterile syringe. Patients were followed up for 15-48 months. Adequate projection was achieved in all patients, and there was no wound dehiscence or complications such as infection. Three patients had successful pregnancies and subsequent breastfeeding that was not adversely affected by the treatment. There was no loss of sensation in any patient during the postoperative period. Our technique for treating an inverted nipple is effective and preserves lactation function and nipple sensation. The method maintains traction for a longer period, which we believe increases the success rate of the surgery for correction of severely inverted nipples.

    To study the microbiology of banana peel being sold in the city of Rio de Janeiro, in an attempt to determine the possibility that the peel may represent a source of infection for women who use it to treat nipple fissures. The following microorganisms were studied in 20 banana peel samples: mesophiles, total coliforms, fecal coliforms, Pseudomonas aeruginosa, lipolytic and proteolytic microorganisms, molds and yeasts, lactic bacteria, and coagulase-positive staphylococcus. The microbiological analyses revealed the occurrence of several typical groups of microorganisms, with the following distribution of positive results being detected in banana peel samples: mesophiles, 100%; total coliforms, 20%; coagulase-positive staphylococcus, 25%; molds and yeasts, 30%; proteolytic microorganisms, 70%; lipolytic microorganisms, 30%, and lactic bacteria, 95%. Fecal coliforms and Pseudomonas aeruginosa were not isolated. The results show the presence of potentially pathogenic microorganisms in levels which could compromise the microbiological quality of the banana peel. Its use for the treatment of nipple fissures can initiate an infectious process.

    We describe a patient with Klinefelter's syndrome associated with multi-focal breast carcinoma and Paget's disease of the nipple. Reviewing the 16 previously documented cases in the world literature, it is apparent that patients with this syndrome have an increased incidence of breast carcinoma. There is no evidence to date to suggest that such tumour is morphologically or biologically different from breast cancer in females and normal men.

The other complications, such as necrosis of the skin flap or areola,seroma, hematoma, or fat necrosis did not occur.Conclusions Since one-stage nipple and breast reconstruction following ASM is an oncologicallysafe, cost-effective, and aesthetically satisfactory procedure, it is a good surgical optionfor early breast cancer patients.

    Male breast cancer is a rare entity accounting for Nipple skin/subcutaneous tumors in men are even rarer. Likewise, true neuroendocrine carcinoma of the breast, defined as > 50% of tumor cells staining for either chromogranin or synaptophysin, is not a common entity, usually occurring in older women. We present the case of a 70-year-old man with a slowly growing nipple mass that had enlarged over the previous 1.5 years. The histology consisted of nests, trabeculae and sheets of basaloid cells with rare abortive gland formation and a pushing edge. The case was originally misdiagnosed as a Merkel cell carcinoma, based largely on histologic morphology. Strong staining for synaptophysin (in greater than 50% of cells), CD56, keratins AE1 : AE3 and Cam 5.2, as well as estrogen receptor and progesterone receptor was noted. Myoepithelial cells within in situ areas were identified using stains for calponin and 4A4, supporting a primary mammary duct origin. Additionally, a substantial portion of cells stained for Gross Cystic Disease Fluid Protein-15 (GCDFP-15), confirming some overlap with sweat duct differentiation. To the best of our knowledge, although reported in the male breast, no case of primary nipple neuroendocrine carcinoma in a male patient has been reported in the literature. The gender of the patient and association with the skin of the chest wall probably contributed to the original misdiagnosis of Merkel cell carcinoma in this patient.

    Free flap monitoring in autologous reconstruction after nipple-sparing mastectomy remains controversial. The authors therefore examined outcomes in nipple-sparing mastectomy with buried free flap reconstruction versus free flap reconstruction incorporating a monitoring skin paddle. Autologous free flap reconstructions with nipple-sparing mastectomy performed from 2006 to 2015 were identified. Demographics and operative results were analyzed and compared between buried flaps and those with a skin paddle for monitoring. Two hundred twenty-one free flaps for nipple-sparing mastectomy reconstruction were identified: 50 buried flaps and 171 flaps incorporating a skin paddle. The most common flaps used were deep inferior epigastric perforator (64 percent), profunda artery perforator (12.1 percent), and muscle-sparing transverse rectus abdominis myocutaneous flaps (10.4 percent). Patients undergoing autologous reconstructions with a skin paddle had a significantly greater body mass index (p = 0.006). Mastectomy weight (p = 0.017) and flap weight (p < 0.0001) were significantly greater in flaps incorporating a skin paddle. Comparing outcomes, there were no significant differences in flap failure (2.0 percent versus 2.3 percent; p = 1.000) or percentage of flaps requiring return to the operating room (6.0 percent versus 4.7 percent; p = 0.715) between groups. Buried flaps had an absolute greater mean number of revision procedures per nipple-sparing mastectomy (0.82) compared with the skin paddle group (0.44); however, rates of revision procedures per nipple-sparing mastectomy were statistically equivalent between the groups (p = 0.296). Although buried free flap reconstruction in nipple-sparing mastectomy has been shown to be safe and effective, the authors' technique has evolved to favor incorporating a skin paddle, which allows for clinical monitoring and can be removed at the time of secondary revision.

    Oxytocin and prostaglandin are hormones responsible for uterine contraction during the third stage of labour. Receptors in the uterine muscles are stimulated by exogenous or endogenous oxytocin leading to uterine contractions. Nipple stimulation or breastfeeding are stimuli that can lead to the secretion of oxytocin and consequent uterine contractions. Consequently, uterine contractions can reduce bleeding during the third stage of labour. To investigate the effects of breastfeeding or nipple stimulation on postpartum haemorrhage (PPH) during the third stage of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (15 July 2015) and reference lists of retrieved studies. Randomised and quasi-randomised controlled trials comparing breast stimulation, breastfeeding or suckling for PPH in the third stage of labour were selected for this review. Two review authors independently assessed studies for inclusion in terms of risk of bias and independently extracted data. Disagreements were resolved by a third review author. We included four trials (4608 women), but only two studies contributed data to the review's analyses (n = 4472). The studies contributing data were assessed as of high risk of bias overall. One of these studies was cluster-randomised and conducted in a low-income country and the other study was carried out in a high-income country. All four included studies assessed blood loss in the third stage of labour. Birth attendants estimated blood loss in two trials. The third trial assessed the hematocrit level on the second day postpartum to determine the effect of the bleeding. The fourth study measured PPH ≥ 500 mL. Nipple stimulation versus no treatmentOne study (4385 women) compared the effect of suckling versus no treatment. Blood loss was not measured in 114 women (59 in control group and 55 in suckling group). After excluding twin pregnancies, stillbirths and neonatal deaths, the main analyses for this trial were performed on

    2014-01-01

    Full Text Available Context: The established techniques that have been used to treat gynaecomastia are said to have relatively less patient satisfaction rate as they leave some visible scars or mild elevation over the nipple areola complex, resulting in aesthetically unsatisfactory results. Even the slightest elevation or smallest scar over nipple areola complex leave patients extremely self conscious and in a dilemma of having a second intervention to get rid of that blemish. Aims: The aim of the study is to achieve - A flat chest without adding a scar and with no chances of re-occurrence of the condition. This article suggests an innovative approach to address the problem. Materials and Methods: The author presents trans-nipple incision approach for the delivery of fibro-glandular tissue component following liposuction for maximum patient satisfaction. This method consists of a unique small criss-cross incision right on the nipple itself for retrieving any volume of tough fibro-glandular tissues. Between the duration of January 2012 to October 2013, 28 male patients of different ages were operated with this technique. Results: The surgery resulted in well-shaped, symmetric chest contour without any visible elevation or additional scars on nipple areola complex. No complications were noticed in any of the patients. Conclusions: The presented technique is proved to have a high patient satisfaction rate and to be promising method to achieve good aesthetic results in gynaecomastia surgery.

    Full Text Available BACKGROUND AND AIM: Sucking of some types of a pacifier may be a risk factor for mal-development of orofacial structures and malocclusion. This study assessed the prevalence of using of different types of pacifier and bottle nipple among 1-24 months old children in Kerman, Iran. METHODS: In this cross-sectional study, a total of 300 mothers interviewed at 20 specialized private pediatric offices in Kerman. The mothers had 1-24 months old children. A checklist includes items about pacifier sucking, bottle feeding habits, as well as mothers’ ability to recognize different kinds of available pacifier and bottle nipple was used. RESULTS: The rate of pacifier-sucking was 37.3%, and use of bottle feeding was 42.3%, and among of the users, 24.0 and 35.7% were used orthodontic (functional types of pacifier and bottle nipple respectively. However, only 28.7% of mothers had adequate ability to recognize orthodontic pacifier and bottle nipple. CONCLUSION: The rates of using orthodontic kind of pacifier and bottle nipple were low, and a few mothers had adequate ability to recognize their differences.

    The efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of breast cancer are still questionable. It is estimated that the local recurrence rates following nipple-sparing mastectomy are very similar to breast-conserving surgery followed by radiotherapy. To assess the efficacy and safety of nipple-sparing mastectomy and areola-sparing mastectomy for the treatment of ductal carcinoma in situ and invasive breast cancer in women. We searched the Cochrane Breast Cancer Group's Specialized Register, the Cochrane Center Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed), Embase (via OVID) and LILACS (via Biblioteca Virtual em Saúde [BVS]) using the search terms "nipple sparing mastectomy" and "areola-sparing mastectomy". Also, we searched the World Health Organization's International Clinical Trials Registry Platform and ClinicalTrials.gov. All searches were conducted on 30th September 2014 and we did not apply any language restrictions. Randomised controlled trials (RCTs) however if there were no RCTs, we expanded our criteria to include non-randomised comparative studies (cohort and case-control studies). Studies evaluated nipple-sparing and areola-sparing mastectomy compared to modified radical mastectomy or skin-sparing mastectomy for the treatment of ductal carcinoma in situ or invasive breast cancer. Two review authors (BS and RR) performed data extraction and resolved disagreements. We performed descriptive analyses and meta-analyses of the data using Review Manager software. We used Cochrane's risk of bias tool to assess studies, and adapted it for non-randomised studies, and we evaluated the quality of the evidence using GRADE criteria. We included 11 cohort studies, evaluating a total of 6502 participants undergoing 7018 procedures: 2529 underwent a nipple-sparing mastectomy (NSM), 818 underwent skin-sparing mastectomy (SSM) and 3671 underwent traditional mastectomy, also known as modified radical

    History of smoking has been implicated as a risk factor for reconstructive complications in nipple-sparing mastectomy (NSM), however there have been no direct analyses of outcomes in smokers and nonsmokers. All patients undergoing NSM at New York University Langone Medical Center from 2006 to 2014 were identified. Outcomes were compared for those with and without a smoking history and stratified by pack-year smoking history and years-to-quitting (YTQ). A total of 543 nipple-sparing mastectomies were performed from 2006 to 2014 with a total of 49 in patients with a history of smoking. Reconstructive outcomes in NSM between those with and without a smoking history were equivalent. Those with a smoking history were not significantly more likely to have mastectomy flap necrosis (p = 0.6251), partial (p = 0.8564), or complete (p = 0.3365) nipple-areola complex (NAC) necrosis. Likewise, active smokers alone did not have a higher risk of complications compared to nonsmokers or those with smoking history. Comparing nonsmokers and those with a less or greater than 10 pack-year smoking history, those with a > 10 pack-year history had significantly more complete NAC necrosis (p = 0.0114, smoking history or >5 YTQ prior to NSM were equivalent to those without a smoking history. We demonstrate that NSM may be safely offered to those with a smoking history although a > 10 pack-year smoking history or <5 YTQ prior to NSM may impart a higher risk of reconstructive complications, including complete NAC necrosis. © 2017 Wiley Periodicals, Inc.

    Nipple-areola complex reconstruction (NAR) is the final procedure in breast reconstruction after the majority of mastectomies. Many methods of NAR have been described, each with inherent advantages and disadvantages depending on local healthy tissue availability, previous scarring and procedures, and the operative morbidity of the NAR technique. Nipple reconstructions may be complicated by scars or previous nipple reconstruction, making the procedure more challenging. We propose the use of the V-Y advancement flap as a new method that is suitable for both novice and experienced surgeons wishing to broaden their range of techniques for difficult nipple reconstructions. A traditional V-Y advancement flap is lifted at the site of the future nipple. Mastectomy scars from prior mastectomy, mammoplasty, or nipple reconstruction can be incorporated into the flap. The flap is folded caudally upon itself and the secondary defect at the apex of the flap is linearly closed. At 6-month postoperative evaluation, adequate nipple projection and patient satisfaction were achieved with this method. The V-Y advancement flap is a suitable method for achieving satisfactory results when faced with challenging NAR. The method is easy to perform, reproducible, has low operative morbidity, and incorporates previous wise pattern mastectomy or mammaplasty scars into the newly reconstructed nipple, thereby decreasing new scar formation on the breast and leading to favorable cosmetic results.

    Nipple-sparing mastectomy (NSM) is increasingly popular for the treatment of selected breast cancers and prophylactic mastectomy. Surgical scarring and esthetic outcomes are important patient-related cosmetic considerations. Today, the concept of minimally invasive surgery has become popular, especially using robotic surgery. The authors report the first case of NSM using the latest version of the da Vinci Xi surgical system (Xi). The final incision used to remove the entire mammary gland was located behind the axillary line. In this position, hidden by the arm of the patient, the incision was not visible and was compatible with immediate breast reconstruction. © 2017 Wiley Periodicals, Inc.

    Nipple-sparing mastectomy (NSM) is a recent advance in the therapeutic and prophylactic management of breast cancer; however, the procedure is associated with increased reconstructive complications. Data on NSM after previous breast augmentation are limited. The authors compared reconstructive complications after NSM between patients with previously augmented breasts and a larger cohort that had not undergone prior augmentation. An approach to NSM that involves 2-stage reconstruction in augmented patients is also described. Medical records of NSMs performed at New York University Langone Medical Center from 2006 to 2013 were reviewed. Data points evaluated included patient characteristics, comorbidities, breast implant plane, and reconstructive complications. Fisher's exact and t tests were used for the comparisons. During the study period, NSMs were performed in 17 augmented breasts at this institution. After NSM, 15 of these breasts underwent implant-based reconstruction and 2 breasts underwent microvascular free flaps. Reconstructive complications included 1 hematoma managed nonoperatively (5.9%) and 1 partial necrosis of the nipple-areola complex (NAC) (5.9%). Compared with the larger nonaugmented cohort (n=332), patients with previously augmented breasts had fewer complications, and there were no statistically significant differences in the rates of mastectomy flap necrosis, partial NAC necrosis, complete NAC necrosis, hematoma, capsular contracture, explantation, implant displacement, seroma, or breast cellulitis. The results indicate that NSM reconstruction is associated with minimal complications in patients with previous augmentation mammaplasty. 4. © 2014 The American Society for Aesthetic Plastic Surgery, Inc.

    Bilateral ductal carcinoma in situ of breast is a very rare disease in men. Ductal carcinoma in situ (DCIS) is an abnormal proliferation that involves the ductal epithelium and it has the potential of evolving into an invasive tumour. Gynaecomastia (female like breast in men) is a benign condition though it is associated with a reported 3% incidence of unilateral invasive breast cancer.2 Synchronous bilateral breast cancer in association with gynaecomastia is exceptionally rare. The recommended treatment for DCIS in male is mastectomy. So far only 2 cases of bilateral DCIS in male patients has been reported in the literature treated with skin and nipple sparing mastectomies. We report another case of synchronous bilateral DCIS in a male treated with skin and nipple sparing mastectomies. A 44 year-old man with history of long-standing gynecomastia. He had no identifiable risk factor for the development of cancer. His pre operative assessment of breast including mammograms was normal. He underwent bilateral subcutaneous mastectomies, with subsequent incidental diagnosis of synchronous bilateral ductal carcinoma in situ. The case was discussed in multidisciplinary team meeting and the need for further surgery was felt including excision of nipple areola complex. However considering patient wishes, cosmetic outcome and recent literature it was decided to preserve nipple areola complex (NAC) with regular follow up evaluation. Our patient at completion of 18 months of treatment is doing well with no signs of local recurrence. PMID:22096697

    This paper summarizes pathological changes that affect microglial cells in the human brain during aging and in aging-related neurodegenerative diseases, primarily Alzheimer's disease (AD). It also provides examples of microglial changes that have been observed in laboratory animals during aging and in some experimentally induced lesions and disease models. Dissimilarities and similarities between humans and rodents are discussed in an attempt to generate a current understanding of microglial pathology and its significance during aging and in the pathogenesis of Alzheimer dementia (AD). The identification of dystrophic (senescent) microglia has created an ostensible conflict with prior work claiming a role for activated microglia and neuroinflammation during normal aging and in AD, and this has raised a basic question: does the brain's immune system become hyperactive (inflamed) or does it become weakened (senescent) in elderly and demented people, and what is the impact on neuronal function and cognition? Here we strive to reconcile these seemingly contradictory notions by arguing that both low-grade neuroinflammation and microglial senescence are the result of aging-associated free radical injury. Both processes are damaging for microglia as they synergistically exhaust this essential cell population to the point where the brain's immune system is effete and unable to support neuronal function.

    Several studies have attempted to identify an objective description of the aesthetically ideal breast, but they have all suffered in their reliability because of having several intrinsic limitations. It is therefore essential to design a template of ideal breast features in order to predict and evaluate aesthetic outcomes in both reconstructive and cosmetic breast surgery. The aim of this study was to determine the aesthetically preferred position of the nipple-areola complex on the breast. A questionnaire was sent by regular mail to 1000 men and 1000 women aged between 16 and 74 years. They were asked to rank the attractiveness of a series of breasts of women in images with different NAC positions. The images showed breasts from two different angles: 12 frontal-view images with both breasts shown, and five side-view images with only one breast shown. All of the breasts had equal dimensions and proportions, with the same areola size but different NAC positions. Statistical analysis of data was carried out. Eight hundred and thirteen of 2000 participants completed the questionnaire. The NAC placement preferred by both genders had a ratio of 40:60 x and 50:50 y, which means that it was best situated in the middle of the breast gland vertically and slightly lateral to the midpoint horizontally. Significant differences were found between the age and gender subgroup preferences. This study identified the preferred position of the nipple-areola complex on the female breast in the general population. This is an important information when planning breast reconstructive and cosmetic surgery. This journal requires that authors assign a level of evidence to each article.

    When offered diets with hay ad libitum, rabbits (Oryctolagus cuniculus) clearly prefer open dishes over nipple drinkers, but whether this preference also applies in guinea pigs (Cavia porcellus) is unsure. We tested the drinker preference of 10 guinea pigs when offered open dishes (OD) and nipple drinkers (ND) simultaneously and measured the amount of water consumed by each animal on four different diets (grass hay 100%, or as 10% of intake on diets of fresh parsley, seed mix or pelleted complete feed, respectively) on either of the drinking systems. All animals ingested the hay portion of the combined diets first. The amount of water consumed differed significantly between individual animals. Animals drank less water on parsley than on the other diets. Nine of 10 animals clearly preferred ND when having a choice, and eight of these drank more when on ND only. The difference between the drinking systems was not consistent across all diets: on hay, similar amounts of water were drunk when on OD or ND only. Differences in water intake were reflected in urine production. Because drinking from ND in guinea pigs involves jaw movements similar to those in chewing, the results could suggest that when motivation for oral processing behaviour is not satisfied by a diet, animals may respond in using ND beyond physiological water necessity. Whereas physiological water requirements are probably better investigated with other drinking systems due to a possible overestimation when using ND, offering ND to pet guinea pigs most likely offers a form of behavioural enrichment that at the same time may increase water intake and hence act as prophylaxis against urolithiasis.

    Full Text Available Background: Oral candidiasis is the most prevalent opportunistic infection affecting the oral mucosa. A number of predisposing factors have the capacity to convert Candida from the normal commensal flora to a pathogenic organism. Oral candidiasis is divided into primary and secondary infection. The primary infections are restricted to the oral and perioral sites, where as secondary infections are accompanied by sistemic mucocutaneous manifestation. Oral thrush is one of the candidiasis primary infection. Some presdiposing factors of oral thrush are neonatal, old people, or where oral microflora is disturbed by the treatment with broad spectrum antibiotics. Final diagnosis is determined by fungal culture examination, although through clinical examination oral thrush can be determined by swabbing the white pseudomembran. Purpose: This case report presents about the importance of using the antiseptic cleanser for baby bottle nipple to prevent oral thrush relaps and shows about peroxide alkaline as the alternatif of antiseptic cleanser for baby bottle nipple that can substitute chlorhexidine gluconat 0.2%. Case: A baby girl, 15 months old, when she was suffering influenza the pediatry gave amoxycillin 125 mg three times a day for ten days. Then the white plaque appeared on her dorsum of tongue. The therapy was Gentian Violet 1% four times a day for ten days was applied on dorsum of the tongue. The patient was suspected to suffer alergy reaction after using nistatin oral suspension four times a day had applied for 1 day. The instruction was doing sterilization for the baby bottle nipple in boiling water. Three days after the baby was cured, the white plaque was appeared on upper n lower lips mucous. Case management: The diagnosis was Oral thrush. The therapy was Gentian violet 1% four times a day for ten days that applied on upper and lower lips mucous.

    For several years, efforts have been made to strengthen collaboration between health professionals with different specializations and to improve patient transition from hospital to home (care). In the Danish health care system, these efforts have concentrated on cancer and heart diseases, whereas...... coordinator, employed at the hospital, is supposed to anticipate discharge and serve as mediator between the hospital and the municipal home care system. Drawing on methods from discourse and interaction analysis, the paper studies the practice of the discharge coordinator in two encounters between patients...... how the home context provides different resources for identification of patient needs and mutual decision making....

    The gross and microscopic pathology of breast cancers in women irradiated for acute postpartum mastitis was compared to the breast cancers found in the sisters of the irradiated women. In considering the lesions in the two populations, the size, location, histologic type, histologic grade, inflammatory response, lymphatic and blood vascular invasion, nipple involvement, axillary lymph node metastases, and menopausal status at the time of diagnosis were statistically indistinguishable. The only parameter that was different in the two populations was the desmoplastic response to the malignant lesion. The control population had more marked fibrosis within the cancers compared with the irradiated women

    Current practice of North Sea States on the discharge and disposal of liquid radioactive wastes to the North Sea are based on the declaration issued at the Second International Conference on the Protection of the North Sea, known as the London Declaration. This has three main points the first of which emphasises the application of the Best Available Technology to protect the North Sea, the second provides a framework on which future controls on radioactive discharges should be based. The third identifies two parts of the framework; to take into account the recommendations of international organizations and that any repositories of radioactive waste which are built should not pollute the North Sea. This chapter looks at how the concensus based on the London Declaration is working, gauges the progress made in the implementation of the policy goal, identifies existing and future areas for concern and proposes ways of strengthening the control of radioactive discharges. The emphasis is on the United Kingdom practice and regulations for liquid wastes, most of which comes from the Sellafield Reprocessing Plant. (author)

    Nipple-sparing mastectomy (NSM) is gaining popularity due to its superior aesthetic results. When reconstructing the breast with free abdominal tissue transfer, we must readdress the recipient vessel, because NSM can cause difficulty in access to the chest vessel. Between June 2006 and March 2011, a total of 92 women underwent NSM with free abdominal tissue transfer. A lateral oblique incision was used for the nipple-sparing mastectomy. For recipient vessels, the internal mammary vessels were chosen if the mastectomy flap did not block access to the vessels. If it did, the thoracodorsal vessels were used. Age, degree of breast ptosis, weight of the mastectomy specimen, and related complications of the internal mammary vessel group and the thoracodorsal vessel group were compared. Thoracodorsal vessels were used as recipient vessels in 59 cases, and internal mammary vessels in 33 cases including 4 cases with perforators of the internal mammary vessels. Breast reconstruction was successful in all cases except one case involving a total flap failure, which was replaced by a silicone gel implant. The internal mammary group and the thoracodorsal group were similar in terms of age, height, breast weight, and degree of ptosis. The flap related complications such as flap loss and take-back operation rates were not significantly different between the two groups. The rate of nipple necrosis was higher in the internal mammary group. The thoracodorsal vessels could produce comparable outcomes in breast reconstruction after nipple-sparing mastectomies. If access to internal mammary vessels is difficult, the thoracodorsal vessel can be a better choice.

    The C-V flap for nipple reconstruction is now one of standard surgical techniques. But decreased projection is still a problem. In recent years, it has been suggested that projection can be more easily maintained when raising of the C-flap is performed with a split thickness dermis. In this study, we examined whether decrease of projection can be prevented by raising of a C-flap with a split dermis rather than with full dermis. A total of 49 consecutive patients who underwent reconstruction of a nipple using the C-V flap technique were enrolled. The patients included 22 who underwent surgery using a C-flap with a full thickness dermis (Group F), and 27 who underwent surgery with raising of a flap with a split thickness dermis (Group S). The size of the reconstructed nipple was measured at 2 weeks, 6 months and 1 year postoperatively for comparison between Groups F and S. Partial necrosis of the C-flap end occurred in 4 subjects in only Group S. The decrease in projection after 1 year postoperatively in Group S was significantly lower than that in Group F. In contrast, the teat base size in Group F tended to be greater than that in Group S, suggesting a tendency for an expanded base using a flap with a full dermis. Our results indicated that it is recommended to use a C-flap with a split dermis for cases with high projection of the nipple on the contralateral side.

    Nipple-areola complex (NAC) and skin flap ischemia and necrosis can occur after nipple-sparing mastectomy (NSM). The purpose of this study was to correlate vascular findings on MRI with outcomes in patients who underwent NSM. Female patients at a single institution who underwent NSM and had a preoperative breast MRI between 2010 and 2014 were identified. Medical records were reviewed for patient demographics, surgical factors, and complications. Magnetic resonance images were reviewed by 2 radiologists, blinded to outcomes, for the presence of dual vs single blood supply to the breast. The association between blood supply on MRI with ischemic and necrotic complications after NSM was analyzed. One hundred and sixty-four NSM procedures were performed in 105 patients (mean age 45.5 years, range 25 to 69 years) who had a preoperative MRI. The majority of procedures were performed for malignancy (89 of 164 [54.3%]) or prophylaxis (73 of 164 [44.5%]). Nipple-areola complex or skin flap ischemia or necrosis occurred in 40 (24.4%) breasts. Ischemia or necrosis after NSM was less likely to occur in breasts with dual compared with single blood supply (20.8% vs 38.2%; p = 0.03). There was no association between surgical complications and age, BMI, smoking history, previous radiation therapy, indication for NSM, surgical specimen weight, surgical incision type, reconstruction approach, or operating surgeon on univariate analysis. Preoperative MRI characterization of breast vascularity can be considered when planning NSM. The presence of a dual blood supply to the breast on MRI is associated with a decreased risk of nipple-areola complex and skin flap ischemia and necrosis after NSM.

    Leiomyoma of the mammary papilla is one of the most uncommon nipple tumors with only 50 cases reported in the literature until now. To the best of our knowledge we present the first report of a nipple leiomyoma that originated from a traumatic abrasion caused by breastfeeding. A 35-year-old healthy Caucasian female with a cauliflower-like tender and pink nodular mass that was approximately 10mm in diameter presented to our out-patients department. The patient suggested that the mass originated from a traumatic abrasion caused by breastfeeding three years ago and it has been slowly growing ever since.An excision biopsy was performed. The histological and immunohistochemical examination confirmed the diagnosis of leiomyoma. There were no postoperative complications or any sign of local recurrence four years postoperatively. Leiomyoma of the mammary papilla is a rare benign neoplasm that usually appears as a solid tender nodule. Differential diagnosis comprises breast carcinoma, leiomyosarcoma and myoid hamartoma. The recommended treatment is complete excision of the tumor with histologically confirmed tumor-free margins otherwise recurrence is possible. A detailed history of the patient's disease can reveal the original etiology. This is an original case report that will have particular interest to plastic surgeons, dermatologists, and pathologists. The pathogenetic mechanism was trauma of the nipple. According to our review of the literature this particular information has never been reported and we think that it may advance our knowledge of this very infrequent tumor.

    Friction welding is a very useful joining process to weld metals which have axially symmetric cross section. In this paper, the feasibility of industry application was determined by analyzing the mechanical properties of weld region for a specimen of tube-to-tube shape for excavator hose nipple with friction welding, and optimized welding variables were suggested. In order to accomplish this object, friction heating pressure and friction heating time were selected as the major process variables and the experiment was performed in three levels of each parameter. An acoustic emission(AE) technique was applied to evaluate the optimal friction welding conditions nondestructively. AE parameters of accumulative count and event were analyzed in terms of generating trend of AE signals across the full range of friction weld. The typical waveform and frequency spectrum of AE signals which is generated by friction weld were discussed. From this study the optimal welding variables could be suggested as rotating speed of 1300 rpm, friction heating pressure of 15 MPa, and friction heating time of 10 sec. AE event was a useful parameter to estimate the tensile strength of tube-to tube specimen with friction weld.

    Nipple-areolar complex (NAC) tattoos are an effective cosmetic solution for creating a finished look following breast reconstruction procedures. NAC tattoos are prone to significant fading, leading patients to seek revisions. This study was designed to quantify changes in NAC tattoo appearance over time. A total of 71 images of 39 patients were analyzed for NAC tattoo color and shape by 5 blinded medical student graders using a customized scoring system. Subsequently, each image was analyzed using ColorPic software (Iconico, New York, NY). Red/green/blue and hue/saturation/value color parameters were collected. Color quantities were normalized to the individual patient's skin tone to control for variability in lighting. Spearman correlations and nonlinear regressions were calculated utilizing GraphPad Prism 6.0 (GraphPad, La Jolla, CA). The length of time after tattoo placement inversely correlated with color score (P tattoo placement was also inversely correlated with all quantitative color parameters. Each color parameter fit a 1-phase exponential decay model. The decline in qualitative color and shape score agrees with clinical experience of tattoo quality declining over time. The color qualities of the tattoo approach those of the patient's skin over time, ultimately reaching a plateau. This can be modeled using a 1-phase decay equation. In practice, tattoo colors may be selected that compensate for the predictable changes that will occur. The results of this study will help optimize tattoo color and may alleviate the need for NAC tattoo revisions.

  8. Characterisation of zinc delivery from a nipple shield delivery system using a breastfeeding simulation apparatus.

    Directory of Open Access Journals (Sweden)

    Rebekah L Scheuerle

    Full Text Available Zinc delivery from a nipple shield delivery system (NSDS, a novel platform for administering medicines to infants during breastfeeding, was characterised using a breastfeeding simulation apparatus. In this study, human milk at flow rates and pressures physiologically representative of breastfeeding passed through the NSDS loaded with zinc-containing rapidly disintegrating tablets, resulting in release of zinc into the milk. Inductively coupled plasma optical emission spectrometry was used to detect the zinc released, using a method that does not require prior digestion of the samples and that could be applied in other zinc analysis studies in breast milk. Four different types of zinc-containing tablets with equal zinc load but varying excipient compositions were tested in the NSDS in vitro. Zinc release measured over 20 minutes ranged from 32-51% of the loaded dose. Total zinc release for sets tablets of the same composition but differing hardness were not significantly different from one another with P = 0.3598 and P = 0.1270 for two tested pairs using unpaired t tests with Welch's correction. By the same test total zinc release from two sets of tablets having similar hardness but differing composition were also not significantly significant with P = 0.2634. Future zinc tablet composition and formulation optimisation could lead to zinc supplements and therapeutics with faster drug release, which could be administered with the NSDS during breastfeeding. The use of the NSDS to deliver zinc could then lead to treatment and prevention of some of the leading causes of child mortality, including diarrheal disease and pneumonia.

    The purpose of this study is to investigate the path of occurred oil-leakage of multi-layered resin-hose as one of multifunctional materials around the caulked joint with a metal nipple and sleeve when excessive cyclic internal pressure was applied onto the hose. Equivalent cyclic axial tensile force was substitutively applied to the hose, where same degree of normal stress was produced in longitudinal direction. Excessive 3 and 5 times of the standard load was applied to the hose. Cyclic loading was paused at every 1000 and 10000 cycles and then designed internal pressure was applied to the hose by a hand-operated pump with water in order to check whether the leakage was occurred around the joint and surface of the hose for safety evaluation. Cyclic fatigue life was defined as the number of loading cycles in which the leakage and the initial damage which was the passage of the ultrasonic wave was observed on the cyclic test. Test results showed the fatigue life at which leakage of water was observed was increased 20 times in case of K=3 compared to that in case of K=5. The cycles of initial damage detected by the ultrasonic wave were passed was increased 3.3 times in case of K=3 compared to that in case of K=5. The fluorescent agent penetrated from the core layer of resin hose to the reinforcement layer in which a half cross section along longitudinal direction in failed specimens was observed after the leak test. The original specimens had the gap between the resin-hose and the nipple and then the gap extended and connected during fatigue cyclic. In this study, it was observed that oil was leaked through narrow gap between the nipple and core layer of resin hose.

    Objective: The purpose of our study was to describe the clinical features, imaging characteristics, pathologic findings and outcome of microinvasive ductal carcinoma in situ (DCISM). Materials and methods: The records of 21 women diagnosed with microinvasive ductal carcinoma in situ (DCISM) from November 1993 to September 2006 were retrospectively reviewed. The clinical presentation, imaging and histopathologic features, and clinical follow-up were reviewed. Results: The 21 lesions all occurred in women with a mean age of 56 years (range, 27-79 years). Clinical findings were present in ten (48%): 10 with palpable masses, four with associated nipple discharge. Mean lesion size was 21 mm (range, 9-65 mm). The lesion size in 62% was 15 mm or smaller. Mammographic findings were calcifications only in nine (43%) and an associated or other finding in nine (43%) [mass (n = 7), asymmetry (n = 1), architectural distortion (n = 1)]. Three lesions were mammographically occult. Sonographic findings available in 11 lesions showed a solid hypoechoic mass in 10 cases (eight irregular in shape, one round, one oval). One lesion was not seen on sonography. On histopathologic examination, all lesions were diagnosed as DCISM, with a focus of invasive carcinoma less than or equal to 1 mm in diameter within an area of DCIS. Sixteen (76%) lesions were high nuclear grade, four (19%) were intermediate and one was low grade (5%). Sixteen (76%) had the presence of necrosis. Positivity for ER and PR was noted in 75% and 38%. Nodal metastasis was present in one case with axillary lymph node dissection. Mean follow-up time for 16 women was 36 months without evidence of local or systemic recurrence. One patient developed a second primary in the contralateral breast 3 years later. Conclusion: The clinical presentation and radiologic appearance of a mass are commonly encountered in DCISM lesions (48% and 57%, respectively), irrespective of lesion size, mimicking findings seen in invasive carcinoma

    Nipple-sparing mastectomy with simultaneous hammock technique direct-to-implant reconstruction is increasingly offered to patients opting for risk-reducing mastectomy. Despite this promising method, patients with macromastia and ptotic breasts remain a challenging group to treat satisfactorily and more often end up undergoing a difficult corrective procedure and experience an unacceptably high rate of failed reconstruction. The authors examined whether targeted preshaping mastopexy/reduction could prepare these patients for a successful nipple-sparing mastectomy/direct-to-implant reconstruction. Patients seeking risk-reducing nipple-sparing mastectomy/direct-to-implant reconstruction at the authors' institutions deemed unfit for a one-stage procedure based on their previous experience were offered a targeted two-stage, risk-reducing mastopexy/reduction followed by a delayed secondary nipple-sparing mastectomy and direct-to-implant reconstruction. Patients were followed up at 3 weeks and 6 or 12 months. Forty-four reconstructions were performed in 22 patients aged 43 years (range, 26 to 57 years). All 44 procedures were completed successfully without any failure or nipple-areola complex losses. Patients' median body mass index was 30 kg/m (range, 22 to 44 kg/m). Six patients were smokers and one had hypertension. Two patients underwent reoperation because of hematoma and fat necrosis. The authors' results demonstrate that a targeted preshaping mastopexy/reduction followed by nipple-sparing mastectomy/direct-to-implant reconstruction can be safely planned in women who opt for a risk-reducing mastectomy and can be performed successfully with a 3- to 4-month time span between operations. On the basis of these results and the superior cosmetic outcome, the two-stage approach has become the authors' standard of care in all such settings. Therapeutic, IV.

    Past studies have shown that women with abnormal cytology or epithelial cells in nipple aspirate fluid (NAF) have an increased relative risk (RR) of breast cancer when compared to women from whom NAF was attempted but not obtained (non-yielders). This study analyzed NAF results from a group of women seen in a breast clinic between 1970–1991 (N = 2480). Our analysis presented here is an aggregate of two sub-groups: women with questionnaire data (n = 712) and those with NAF visits beginning in 1988 (n = 238), the year in which cancer case information was uniformly collected in California. Cytological classification was determined for a group of 946 women using the most abnormal epithelial cytology observed in fluid specimens. Breast cancer incidence and mortality status was determined through June 2006 using data from the California Cancer Registry, California Vital Statistics and self-report. We estimated odd ratios (ORs) for breast cancer using logistic regression analysis, adjusting for age. We analyzed breast cancer risk related to abnormality of NAF cytology using non-yielders as the referent group and breast cancer risk related to the presence or absence of epithelial cells in NAF, using non-yielders/fluid without epithelial cells as the referent group. Overall, 10% (93) of the 946 women developed breast cancer during the follow-up period. Age-adjusted ORs and 95% confidence intervals (C.I.) compared to non-yielders were 1.4 (0.3 to 6.4), 1.7 (0.9 to 3.5), and 2.0 (1.1 to 3.6) for women with fluid without epithelial cells, normal epithelial cells and hyperplasia/atypia, respectively. Comparing the presence or absence of epithelial cells in NAF, women with epithelial cells present in NAF were more likely to develop breast cancer than non-yielders or women with fluid without epithelial cells (RR = 1.9, 1.2 to 3.1). These results support previous findings that 1) women with abnormal epithelial cells in NAF have an increased risk of breast cancer when compared to

    2018-01-01

    Conclusion:. The use of acellular dermal matrix in nipple-sparing mastectomy and implant-based breast reconstruction can be done with acceptable complication rates in selected patients. We recommend future studies to include specific definitions when reporting complication rates. Furthermore, future studies should elaborate on demographic characteristics of the included study samples and include predictor analysis to enhance knowledge of high risk patients.

    Full Text Available Background: Implant-based breast reconstruction after mastectomy has recently been reported to be the preferred type of surgery among breast-specific surgeons and plastic surgeons. Aims: To explore the significant clinicopathological factors associated with long-term outcome related to local recurrences of the nipple among patients who underwent immediate breast reconstruction with tissue expander or implant after mastectomy. Study Design: Retrospective cohort. Methods: From January 2007 to January 2013, 51 breast cancer patients who underwent immediate breast reconstruction with tissue expander or implant were retrospectively analysed. Patients’ demographic data, clinicopathological characteristics, and clinical outcome by disease-free survival and disease-specific survival analyses were determined. Results: The median follow-up was 64 (31-114 months. Of the 57 mastectomies, 41 were skin sparing mastectomy (72% and 16 were nipple-areola sparing mastectomy (28%. Immediate breast reconstruction surgery included tissue expander (n=46, 81% or implant (n=11, 19% placement. The molecular subgroups of 47 invasive cancers were as follows: luminal A (n=23, 49%, luminal B (n=16, 34%, non-luminal HER2 (n=5, 10.6, triple negative breast cancer (n=3, 6.4%. The 5-years disease-specific survival, disease-free survival, and locoregional recurrence-free survival rates were 96.8%, 90%, and 97.6% respectively. Patients with luminal A cancer were found to have an improved 5-year disease-free survival time than other (luminal A; 100% vs. non-luminal A; 78%; p=0.028. Of the 14 nipple-areola sparing mastectomy, 13 had a close median tumour distance to nipple-areola complex (<20 mm with a 5-year locoregional recurrence free survival of 100%. Conclusion: Immediate breast reconstruction with implant or tissue expander can be safely applied in patients undergoing skin sparing mastectomy or nipple-areola sparing mastectomy. Patients with luminal-A type show the most

    2015-01-01

    Full Text Available Fibroadenomas are common, benign breast tumors that usually affect women in the second and third decade of life. Giant fibroadenomas often cause significant concern for the patient or family regarding malignant potential and altered breast development. Most fibroadenomas are benign. Local excision of small lesions through a circumareolar or inframammary incision rather than radical surgery is appropriate. Breast ultrasound represents the most commonly used imaging modality for the study of pediatric female breast masses and fibroadenomas. Detailed descriptions of the sonographic appearances of fibroadenomas in young girls are sparse. We believe that surgical treatment for the patient should include tumor extirpation and immediate restoration of breast appearance, minimizing visible scars, protection of the developing breast bud, nipple, and areola. This modality reduces psychosocial comorbidity.

    2015-11-01

    Pathology is the field of medicine that studies diseases. Ancient Greece hosted some of the earliest societies that laid the structural foundations of pathology. Initially, knowledge was based on observations but later on the key elements of pathology were established based on the dissection of animals and the autopsy of human cadavers. Christianized Greece under Ottoman rule (1453-1821) was not conducive to the development of pathology. After liberation, however, a series of events took place that paved the way for the establishment and further development of the specialty. The appointment in 1849 of two Professors of Pathology at the Medical School of Athens for didactical purposes proved to be the most important step in fostering the field of pathology in modern Greece. Presently in Greece there are seven university departments and 74 pathology laboratories in public hospitals, employing 415 specialized pathologists and 90 residents. The First Department of Pathology at the Medical School of Athens University is the oldest (1849) and largest in Greece, encompassing most pathology subspecialties.

    To review research results on the relationship between pathological gambling and criminality, published in 2007 and 2008, in English and in Spanish. An important association between pathological gambling and criminality was confirmed in populations of anonymous gamblers, helpline callers and substance abusers. Helplines provide a timely service to gamblers who have not reached the maximum stages in the development of a pathological gambling pattern. Pathological gambling is associated with violence in couples and dysfunctional families. Inversely, violence is also an antecedent promoting vulnerability toward pathological gambling. Impulsiveness shows diverse relationships with pathological gambling and violence as well. A pathological gambler's involvement in crime is exceptionally considered without responsibility by justice, but it may be an indicator of the disorder severity and the need for special therapeutic tactics. While reviewing the present study, research work was published that contributed to a better understanding of the association between pathological gambling and criminality and went further into their complex relationship and the formulation of explanatory models related to impulsiveness.

    Neonates are particularly challenging to treat. A novel patented drug delivery device containing a rapidly disintegrating tablet held within a modified nipple shield (NSDS) was designed to deliver medication to infants during breastfeeding. However concerns exist around dermatological nipple tolerability with no pharmaceutical safety assessment guidance to study local tissue tolerance of the nipple and the areola. This is the first Slug Mucosal Irritation (SMI) study to evaluate irritancy potential of GRAS excipients commonly used to manufacture rapidly disintegrating immediate release solid oral dosage form METHODS: Zinc sulphate selected as the antidiarrheal model drug that reduces infant mortality, was blended with functional excipients at traditional levels [microcrystalline cellulose, sodium starch glycolate, croscarmellose sodium, magnesium stearate]. Slugs were exposed to blends slurried in human breast milk to assess their stinging, itching or burning potential, using objective values such as mucus production to categorize irritation potency RESULTS: Presently an in vivo assay, previously validated for prediction of ocular and nasal irritation, was used as an alternative to vertebrate models to anticipate the potential maternal dermatological tolerability issues to NSDS tablet components. The excipients did not elicit irritancy. However, mild irritancy was observed when zinc sulphate was present in blends. These promising good tolerability results support the continued investigation of these excipients within NSDS rapidly disintegrating tablet formulations. Topical local tolerance effects being almost entirely limited to irritation, the slug assay potentially adds to the existing preformulation toolbox, and may sit in between the in vitro and existing in vivo assays.

    Rapid advances in stem cell biology and regenerative medicine have opened new opportunities for better understanding disease pathogenesis and the development of new diagnostic, prognostic, and treatment approaches. Many stem cell niches are well defined anatomically, thereby allowing their routine pathological evaluation during disease initiation and progression. Evaluation of the consequences of genetic manipulations in stem cells and investigation of the roles of stem cells in regenerative medicine and pathogenesis of various diseases such as cancer require significant expertise in pathology for accurate interpretation of novel findings. Therefore, there is an urgent need for developing stem cell pathology as a discipline to facilitate stem cell research and regenerative medicine. This review provides examples of anatomically defined niches suitable for evaluation by diagnostic pathologists, describes neoplastic lesions associated with them, and discusses further directions of stem cell pathology.

    Full Text Available Abstract Background Detection of cytologic atypia in nipple aspirate fluid (NAF has been shown to be a predictor of risk for development of breast carcinoma. Manual collection of NAF for cytologic evaluation varies widely in terms of efficacy, ease of use, and patient acceptance. We investigated a new automated device for the non-invasive collection of NAF in the office setting. Methods A multi-center prospective observational clinical trial involving asymptomatic women designed to assess fluid production, adequacy, safety and patient acceptance of the HALO NAF Collection System (NeoMatrix, Irvine, CA. Cytologic evaluation of all NAF samples was performed using previously described classification categories. Results 500 healthy women were successfully enrolled. Thirty-eight percent (190/500 produced fluid and 187 were available for cytologic analysis. Cytologic classification of fluid producers showed 50% (93/187 Category 0 (insufficient cellular material, 38% (71/187 Category I (benign non-hyperplastic ductal epithelial cells, 10% (18/187 Category II (benign hyperplastic ductal epithelial cells, 3% (5/187 Category III (atypical ductal epithelial cells and none were Category IV (unequivocal malignancy. Overall, 19% of the subjects produced NAF with adequate cellularity and 1% were found to have cytologic atypia. Conclusion The HALO system is a simple, safe, rapid, automated method for standardized collection of NAF which is acceptable to patients. Cytologic assessment of HALO-collected NAF showed the ability to detect benign and pre-neoplastic ductal epithelial cells from asymptomatic volunteers.

    The human breast is likely exposed to Al (aluminium) from many sources including diet and personal care products. Underarm applications of aluminium salt-based antiperspirant provide a possible long-term source of exposure, especially after underarm applications to shaved and abraded skin. Al research in breast fluids likely reflects the intraductal microenvironment. We found increased levels of aluminium in noninvasively collected nipple aspirate fluids (NAF) from 19 breast cancer patients compared with 16 healthy control subjects (268 vs 131 μg/l, respectively; p Aluminium content and carbonyl levels showed a significant positive linear correlation (r(2) 0.6628, p aluminium salts) we also found a significantly increased levels of pro-inflammatory cytokines (IL-1β, IL-6, IL-12 p70, and TNF-α) and chemoattractant CC and CXC chemokines (IL-8, MIP-1α and MCP-1). In 12 invasive cancer NAF samples we found a significant positive linear correlation among aluminium, carbonyls and pro-inflammatory IL-6 cytokine (Y = 64.79x-39.63, r(2) 0.8192, p aluminium ions in oxidative and inflammatory status perturbations of breast cancer microenvironment, suggesting aluminium accumulation in breast microenvironment as a possible risk factor for oxidative/inflammatory phenotype of breast cells. © 2013.

    Although experts have long thought that the problems of gambling involved only adults, recent studies tend to show that teenagers are also affected. The objective of this paper is to show the characteristics of pathological gambling in adolescents. This review focuses on the clinical features, prevalence, psychopathology, prevention and treatment of this disorder. A review of the medical literature was conducted, using PubMed, using the following keywords alone or combined: pathological gambling, dependence, addiction and adolescents. We selected 12 English articles from 1997 to 2014. Recent work estimate that between 4 and 8% of adolescents suffer from problem gambling, and the prevalence of pathological gambling is 2-4 times higher in adolescents than in adults. The term adolescent pathological gambler starts early around the age of 10-12 years, with a quick change of status from casual to that of problem gambler and player. Complications appear quickly and comorbidities are common. There is no curative pharmacological treatment approved by health authorities. Pathological gambling among adolescents has grown significantly in recent years and should be promptly taken care of. Further studies must be performed to improve our understanding of this problem among adolescents. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Soma authors suggested that MR imaging could rapresent an effective diagnostic alternative in the study of pathologic conditions of mother and fetus during pregnancy. To verify the actual role of MR imaging, we examined 20 patients in the 2nd and 3rd trimester of gestation, after a preliminary US examination. Fifteen patients presented fetal or placental pathologies; in 4 patients the onset of the pathologic condition occurred during pregnancy; in 1 case of US diagnosis of fetal ascites, MR findings were nornal and the newborn was healty. As for placental pathologies, our series included a case of placental cyst, two hematomas between placenta and uterine wall, and two cases of partial placenta previa. As for fetal malformation, we evaluated a case of omphalocele, one of Prune-Belly syndrome, a case of femoral asimmetry, one of thanatophoric dwarfism, a case of thoracopagus twins with cardiovascular abnormalities, two fetal hydrocephali, and three cases of pyelo-ureteral stenosis. As for maternal pathologies during pregnancy, we observed a case of subserous uterine fibromyoma, one of of right hydronephrosis, one of protrusion of lumbar invertebral disk, and a large ovarian cyst. In our experience, MR imaging exhibited high sensitivity and a large field of view, which were both useful in the investigation of the different conditions occurring during pregnancy. In the evaluation of fetal and placental abnormalities, especially during the 3rd trimester, the diagnostic yieldof MR imaging suggested it as a complementary technique to US for the evaluation of fetal malformation and of intrauterine growth retardation

    Autopsy numbers in Australian hospitals have declined markedly during the past decade despite evidence of a relatively static rate of demonstrable clinical misdiagnosis during this time. The reason for this decrease in autopsy numbers is multifactorial and may include a general lack of clinical and pathologic interest in the autopsy with a possible decline in autopsy standard, a lack of clinicopathologic correlation after autopsies, and an increased emphasis on surgical biopsy reporting within hospital pathology departments. Although forensic autopsies are currently maintaining their numbers, it is incumbent on forensic pathologists to demonstrate the wealth of important information a carefully performed postmortem examination can reveal. To this end, the Pathology Division of the Victorian Institute of Forensic Medicine has instituted a program of minimum standards in varied types of coroner cases and commenced a system of internal and external audit. The minimum standard for a routine, sudden, presumed natural death is presented and the audit system is discussed.

    2018-04-01

    Otosclerosis is pathologically characterized by abnormal bony remodeling, which includes bone resorption, new bone deposition, and vascular proliferation in the temporal bone. Sensorineural hearing loss in otosclerosis is associated with extension of otosclerosis to the cochlear endosteum and deposition of collagen throughout the spiral ligament. Persistent or recurrent conductive hearing loss after stapedectomy has been associated with incomplete footplate fenestration, poor incus-prosthesis connection, and incus resorption in temporal bone specimens. Human temporal bone pathology has helped to define the role of computed tomography imaging for otosclerosis, confirming that computed tomography is highly sensitive for diagnosis, yet limited in assessing cochlear endosteal involvement.

    In a thermonuclear device, etc. impurities adsorbed to inner walls of a vacuum vessel by glow discharge are released to clean the vacuum vessel for preventing intrusion of the impurities into plasmas. The object of the present invention is to minimize the capacity of a power source equipment for the glow discharge device to the least extent. That is, a stabilization resistance is connected in series between each of a plurality of anodes which are inserted and arranged at the inside of a vacuum vessel as a cathode and a power source respectively. The resistance value R is selected so as to satisfy the relation: R < (Vi - Vm)/Ii, in which Vi: glow discharge starting voltage, Vm: glow discharge keeping voltage, Ii: glow discharge starting current. Accordingly, if a voltage is applied from a power source to a plurality of anodes, scattering of electric discharge between the anodes can be suppressed and the effect of voltage drop during discharge by the stabilization resistance can be eliminated. As a result, it is possible to provide an economically advantageous glow discharge device with the capacity for the power source facility being to the least extent. (K.M.)

    A method and apparatus are given for producing coaxial arc discharges in an evacuated enclosure and within a strong, confining magnetic field. The arcs are maintained at a high potential difference. Electrons will diffuse to the more positive arc from the negative arc, and positive ions will diffuse from the more positive arc to the negative arc. Coaxial arc discharges have the advantage that ions which return to strike the positive arc discharge will lose no energy since they do not strike a solid wall or electrode. Those discharges are useful in confining an ionized plasma between the discharges, and have the advantage of preventing impurities from the walls of the enclosure from entering ihe plasma area because of the arc barrier set up bv the cylindrical outer arc.

  7. Modelling electric discharge chemistry

    1991-07-01

    The chemistry occurring in a electric discharge was modelled to predict how it would be influenced by discharge conditions. The discharge was characterized by a calculated Boltzmann electron-energy distribution, from which rate constants for electron-molecule processes in air were determined. These rate constants were used in a chemical kinetics calculation that also included reactions between neutral molecules, ions, free radicals and electronically excited species. The model describes how the discharge chemistry was influenced by humidity, electric field, electron number density, and concentrations of key reagents identified in the study. The use of an electric discharge to destroy airborne contaminant molecules was appraised, the targeted contaminants being CF 2 Cl 2 , HCN, and SO 2 . The modelling results indicate that an electric discharge should be able to remove HCN and CF 2 Cl 2 effectively, especially if the discharge conditions have been optimized. Effective destruction is achieved with a moderate electric field (over 1 x 10 -15 V.cm 2 ), a substantial electron number density (over 1 x 10 12 cm -3 ), and the presence of H 2 0 in the process air. The residence time in the discharge was also shown to be important in contaminant destruction. An attempt was made to explain the results of the electric discharge abatement of SO 2 , a component of a simulated flue-gas mixture. Results from the model indicate that the discharge parameters that increase the concentration of hydroxyl radical also increase the rate of decomposition of SO 2 . An objective of the study was to explain the apparent enhancement of SO 2 destruction by the presence of a small amount of NO 2 . It was thought that a likely explanation would be the stabilization of HOSO 2 , an important intermediate in the oxidation of SO 2 by NO 2 . (49 figs., 14 tabs., 75 refs.)

Fractures through benign and malignant bone tumours should be recognised and managed appropriately by the treating orthopaedic surgeon. The most common benign bone tumours that cause pathological fractures in children are unicameral bone cysts, aneurysmal bone cysts, non-ossifying fibromas and fibrous dysplasia. Although pathological fractures through a primary bone malignancy are rare, these should be recognised quickly in order to achieve better outcomes. A thorough history, physical examination and review of plain radiographs are crucial to determine the cause and guide treatment. In most benign cases the fracture will heal and the lesion can be addressed at the time of the fracture, or after the fracture is healed. A step-wise and multidisciplinary approach is necessary in caring for paediatric patients with malignancies. Pathological fractures do not have to be treated by amputation; these fractures can heal and limb salvage can be performed when indicated. PMID:23610658

  11. Next-Generation Pathology.

    The field of pathology is rapidly transforming from a semiquantitative and empirical science toward a big data discipline. Large data sets from across multiple omics fields may now be extracted from a patient's tissue sample. Tissue is, however, complex, heterogeneous, and prone to artifact. A reductionist view of tissue and disease progression, which does not take this complexity into account, may lead to single biomarkers failing in clinical trials. The integration of standardized multi-omics big data and the retention of valuable information on spatial heterogeneity are imperative to model complex disease mechanisms. Mathematical modeling through systems pathology approaches is the ideal medium to distill the significant information from these large, multi-parametric, and hierarchical data sets. Systems pathology may also predict the dynamical response of disease progression or response to therapy regimens from a static tissue sample. Next-generation pathology will incorporate big data with systems medicine in order to personalize clinical practice for both prognostic and predictive patient care.

    This talk is an overview of discharge lamp technology commonly employed in general lighting, with emphasis on issues pertinent to lighting for plant growth. Since the audience is primarily from the plant growth community, and this begins the light source part of the program, we will start with a brief description of the discharge lamps. Challenges of economics and of thermal management make lamp efficiency a prime concern in controlled environment agriculture, so we will emphasize science considerations relating to discharge lamp efficiency. We will then look at the spectra and ratings of some representative lighting products, and conclude with a discussion of technological advances.

    The reconstruction of the body shape after post-bariatric surgery or high-grade gynecomastia involves, besides skin tightening, the repositioning of anatomical, apparent landmarks. The surgeon usually defines these during the preoperative planning. In particular, the positions of the nipple-areola complexes (NAC) should contribute to the gender-appropriate appearance. While in the female breast numerous methods have been developed to determine the optimal position of the NACs, there are only a few, metric and often impractical algorithms for positioning the nipples and areoles in the male. With this study, we show the accuracy of the intuitive positioning of the nipple-areola complex in men. From a pre-examined and measured quantity of 10 young and healthy men, six subjects were selected, which corresponded, on the basis of their chest and trunk dimensions, to the average of known data from the literature. The photographed frontal views were retouched in two steps. Initially, only the NACs were removed and the chest contours were left. In a second step, all contours and the navel were blurred. These pictures were submitted to resident and consultant plastic surgeons, who were asked to draw the missing NACs without any tools. The original positions of the nipples were compared with the inscriptions. Furthermore, the results were compared between the contoured and completely retouched pictures and between the residents and consultants. A total of 8 consultants and 7 residents were included. In the contoured and completely retouched images, a significant deviation of the marked positions of the missing features was found. The height of the NAC was determined somewhat more precisely than the vertical position. There was no significant difference between the contoured and completely retouched images, with a discretely more accurate tendency on the contoured images. In comparison with the professional experience, the consultants were tangentially more precise, but

    The aim of this study was to assess the efficacy of suction-assisted liposuction (SAL) in Simon grade 2b gynecomastia and its effect on sternal notch to nipple areola (SNN) distance. A retrospective analysis was performed on 21 patients with grade 2b gynecomastia who underwent SAL. Preoperative and postoperative SNN distances of the patients were measured, the results were analysed using a Mann-Whitney U test and a p-value gynecomastia and shortens the SNN distance by 1 cm, but further clinical studies are required to support this conclusion.

As specialists, pathology informaticians need a broad skill set, including aptitude with information fundamentals, information systems, workflow and process, and governance and management. Currently, many of those seeking training in pathology informatics additionally choose training in a second subspecialty. Combining pathology informatics training with molecular pathology is a natural extension, as molecular pathology is a subspecialty with high potential for application of modern biomedical informatics techniques. Methods and Results: Pathology informatics and molecular pathology fellows and faculty evaluated the current fellowship program′s core curriculum topics and subtopics for relevance to molecular pathology. By focusing on the overlap between the two disciplines, a structured curriculum consisting of didactics, operational rotations, and research projects was developed for those fellows interested in both pathology informatics and molecular pathology. Conclusions: The scope of molecular diagnostics is expanding dramatically as technology advances and our understanding of disease extends to the genetic level. Here, we highlight many of the informatics challenges facing molecular pathology today, and outline specific informatics principles necessary for the training of future molecular pathologists.

    Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a glow discharge of alternating current with strongly contracted positive column with current densities reaching 10(3) A/cm(2). The plasma electron density and electrical conductivities in the channel were found be 10(16) cm(-3) and (1-2) Ohm(-1) cm(-1), respectively. The discharge interrupts every instance when the discharge-driving AC voltage crosses zero and re-ignites again every next half-wave at the moment when the instant voltage exceeds the breakdown threshold.

    To review the specific radiological signs of male breast pathology observed in our center over the past five years, as well as the pertinent medical literature. A retrospective study was carried out of the 47 mammographic studies performed in 41 men. Oblique mediolateral and craniocaudal views were employed. The distribution of different types of male breast pathology among our patients was as follows: gynecomastia was detected in 30 cases (73.1%), pseudogynectomastia in 4 (9.7%), carcinoma in 3(7.3%), abscess in 2 (4.9%), lipoma in 1 (2.5%) and epidermoid cyst in the remaining patient (2.5%). The results obtained agree with those reported in the literature reviewed. The most significant findings were the low incidence of carcinoma and the high rate of gynecomastia. (Author) 26 refs

    Aspergilloma refers to a fungal ball formed by saprophytic overgrowth of Aspergillus species and is seen secondary to cavitatory/cystic respiratory diseases. Paucity of clinical and pathological data of aspergilloma in India prompted us to analyze cases of aspergilloma over 15 years. The clinical features were recorded in all and correlated with detailed pathological examination. Aspergillomas were identified in 41 surgical excisions or at autopsy. There was male predominance; half the patients were in their fourth decade. Episodic hemoptysis was the commonest mode of presentation (85.4%). Forty aspergillomas were complex, occurring in cavitatory lesions (82.9%) or in bronchiectasis (14.6%). Simple aspergilloma was seen as an incidental finding in only one. Tuberculosis was the etiological factor in 31 patients, producing cavitatory or bronchiectatic lesions; other causes were chronic lung abscess and bronchiectasis (unrelated to tuberculosis). Surgical resections are endorsed in view of high risk of unpredictable, life-threatening hemoptysis.

    In France, consumption of gambling games increased by 148% between 1960 and 2005. In 2004, gamblers lost approximately 0.9% of household income, compared to 0.4% in 1960. This represents approximately 134 Euros per year and per head. In spite of this important increase, the level remains lower than the European average (1%). However, gambling practices may continue to escalate in France in the next few years, particularly with the recent announce of the legalisation of online games and sports betting. With the spread of legalised gambling, pathological gambling rates may increase in France in the next years, in response to more widely available and more attractive gambling opportunities. In this context, there is a need for better understanding of the risk factors that are implicated in the development and maintenance of pathological gambling. This paper briefly describes the major risk factors for pathological gambling by examining the recent published literature available during the first quarter of 2008. This documentary basis was collected by Inserm for the collective expert report procedure on Gambling (contexts and addictions). Seventy-two articles focusing on risk factors for pathological gambling were considered in this review. Only 47 of them were taken into account for analysis. The selection of these 47 publications was based on the guide on literature analysis established by the French National Agency for Accreditation and Assessment in Health (ANAES, 2000). Some publications from more recent literature have also been added, mostly about Internet gambling. We identify three major types of risk factors implicated in gambling problems: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors), and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling seems to be

    The most common man-made discharge is a lamp. Even though lamps are often considered a mature technology, the discharge physics is often poorly understood. Two recent initiatives discussed here show that plasma research can help to make significant improvements. First we discuss color separation in metal halide lamps, which is a problem that prevents these highly efficient lamps from being used in more applications. Secondly a novel lamp concept is presented that may replace the current mercury based fluorescent lamps

  17. Chaos in gas discharges

    International Nuclear Information System (INIS)

    Piel, A.

    1993-01-01

    Many gas discharges exhibit natural oscillations which undergo a transition from regular to chaotic behavior by changing an experimental parameter or by applying external modulation. Besides several isolated investigations, two classes of discharge phenomena have been studied in more detail: ionization waves in medium pressure discharges and potential relaxation oscillations in filament cathode discharges at very low pressure. The latter phenomenon will be discussed by comparing experimental results from different discharge arrangements with particle-in-cell simulations and with a model based on the van-der-Pol equation. The filament cathode discharge has two stable modes of operation: the low current anode-glow-mode and the high current temperature-limited-mode, which form the hysteresis curve in the I(U) characteristics. Close to the hysteresis point of the AGM periodic relaxation oscillations occur. The authors demonstrate that the AGM can be understood by ion production in the anode layer, stopping of ions by charge exchange, and trapping in the virtual cathode around the filament. The relaxation oscillations consist of a slow filling phase and a rapid phase that invokes formation of an unstable double-layer, current-spiking, and ion depletion from the cathodic plasma. The relaxation oscillations can be mode-locked by external modulation. Inside a mode-locked state, a period doubling cascade is observed at high modulation degree

    Full Text Available Pathology is a study of disease which deals with etiology, pathogenesis and morphological features and the associated clinical features. Pathology acts as a bridge that fills the gap between basic sciences and clinical medicine. With proper understanding of pathological processes, one can understand the disease process. In Nepal, since the beginning of medical school teaching, Pathology as a basic science discipline and is a component of the preclinical medical school curriculum.Pathology teaching in 19th century was vague, disorganized and very little, though precious. The lectures used to be conducted by surgeons. At Barts, surgeon Sir James Paget had taught surgical pathology. The real revolution in pathology teaching began in the early 1900s when, spurred on by increasing understanding of disease mechanisms, pathology began to be accepted as a specialty in its own right.During the early and mid of 20th century, pathology teaching was a part of clinical teaching with daily, autopsy demonstration. By the late 1980s, significant change had taken place. In many medical schools, debate started regarding relevance of vigorous preclinical teaching. Then system-based approach was incorporated and traditional preclinical course had been abandoned. With this pathology teaching also began to change with pathologists being involved in teaching histology, often alongside pathology to highlight its clinical relevance. In medical schools the pathology teaching time was cut. Autopsy demonstrations, which had been so popular with generations of medical students, were becoming irregular and less well attended.Though teaching of pathology in blocks to ‘avoid fragmentation’ has disappeared in western countries; it is still practice in Nepal. In western countries there was traditional practice of teaching general pathology in the first two years and systemic pathology in the clinical years. Now pathology teaching is integrated throughout the course. A

    The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

A pesar de ello, el aspecto más notable a mejorar está en la reconstrucción del pezón, dada la frecuente disconformidad de las pacientes con la proyección conseguida a lo largo del tiempo por la posible reabsorción del mismo.The creation of the nipple-areola complex is the latest time in breast reconstruction, transforming the reconstruction of the breast mound into a real breast. We have to consider the reconstruction of the areola and the nipple as the culmination of breast reconstruction. There are a lot of documented techniques for nipple-areola complex reconstruction. The aim of this study is to determine the grade of psychological satisfaction of patients after this reconstruction This study was designed as a retrospective clinic review of 60 patients. After reviewing medical histories, the patients were interviewed and asked to complete a questionnaire. The most common desired aspect was to correct the absence/lost of nipple projection. However, 22% of patients answered they would not change anything regarding their reconstruction. The satisfaction with the mammary mound was excellent or good for 68%, normal for 23 % and poor for 9 %. On the other hand, satisfaction for the nippleareola complex reconstruction was excellent or good for 50%, normal for 45% and poor for 5%. There were no statistical differences among the different techniques depending on the time between the mastectomy intervention and the third reconstruction (p=0,06. For nipple reconstruction, the contralateral nipple donation technique offered more satisfaction (2.67 points and projection (7.23 points. In spite of the differences in their means, there were no statistically significant differences. Taking into account the technique used for the areola reconstruction, the donation-graft of inguinal skin was the one that

    Breast reconstruction for previously augmented patients differs from breast reconstruction for nonaugmented patients. Many surgeons regard conservation therapy as not feasible for these patients because of implant complications, whether radiotherapy-induced or not. Despite this, most authors agree that mastectomy with immediate breast reconstruction is the most suitable choice, ensuring both a good cosmetic result and a low complication rate. Implant retention or removal remains a controversial topic in addition to the best available surgical technique. This study reviewed the authors' experience with immediate breast reconstruction after skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) with anatomically definitive implants. The retrospective records of 12 patients were examined (group A). These patients were among 254 patients who underwent SSM or NSM for breast carcinoma. The control group comprised 12 of the 254 patients submitted to SSM or NSM (group B) who best matched the 12 patients in the studied group. All of them underwent immediate breast reconstruction, with an anatomically definitive implant placed in a submuscular-subfascial pocket. The demographic, technical, and oncologic data of the two groups were compared as well as the aesthetic outcomes using the Breast Q score. The proportion of complications, the type of implant, the axillary lymph node procedure, and the histology were compared between the two groups using Fisher's exact test. Student's t test was used to compare the scores for the procedure-specific modules of the breast Q questionnaire in the two groups. A validated patient satisfaction score was obtained using the breast Q questionnaire after breast reconstruction. The demographic, technical, and oncologic characteristics were not significantly different between the two groups. The previously augmented patients reported a significantly higher level of satisfaction with their breast than the control patients. The scores

    Apoptosis (programmed cell death) occurs normally for maitenance of tissue homeostasis and play an important role in morphogenesis, embriogenesis and tissue growth. On the other hand, apoptosis may be involved in different pathological processes such as malignancy, infectious diseases and autoimmune disorders. Apoptosis is regulated by various mediators. Caspases, death receptors, mitochondria, Bcl-2 protoncogenes and tumor supressor genes are considered to be the most important of them. Advance in apoptosis regulation research suggests enormouse facilities for therapy of wide range of human illnesses.

    Effective marketing of the pathology practice is essential in the face of an increasingly competitive market. Successful marketing begins with a market-driven planning process. As opposed to the traditional planning process used in health care organizations, a market-driven approach is externally driven. Implementing a market-driven plan also requires recognition of the definition of the service. Each market to which pathologists direct their service defines the service differently. Recognition of these different service definitions and creation of a product to meet these needs could lead to competitive advantages in the marketplace.

    There is a large scala of pathology affecting the vestibulocochlear nerve. Magnetic resonance imaging is the method of choice for the investigation of pathology of the vestibulocochlear nerve. Congenital pathology mainly consists of agenesis or hypoplasia of the vestibulocochlear nerve. Tumoral pathology affecting the vestibulocochlear nerve is most frequently located in the internal auditory canal or cerebellopontine angle. Schwannoma of the vestibulocochlear nerve is the most frequently found tumoral lesion followed by meningeoma, arachnoid cyst and epidermoid cyst. The most frequently encountered pathologies as well as some more rare entities are discussed in this chapter.

    Alzheimer’s disease (AD) is the most common form of dementia and remains a growing worldwide health problem. As life expectancy continues to increase, the number of AD patients presenting for surgery and anesthesia will steadily rise. The etiology of sporadic AD is thought to be multifactorial, with environmental, biological and genetic factors interacting together to influence AD pathogenesis. Recent reports suggest that general anesthetics may be such a factor and may contribute to the development and exacerbation of this neurodegenerative disorder. Intra-neuronal neurofibrillary tangles (NFT), composed of hyperphosphorylated and aggregated tau protein are one of the main neuropathological hallmarks of AD. Tau pathology is important in AD as it correlates very well with cognitive dysfunction. Lately, several studies have begun to elucidate the mechanisms by which anesthetic exposure might affect the phosphorylation, aggregation and function of this microtubule-associated protein. Here, we specifically review the literature detailing the impact of anesthetic administration on aberrant tau hyperphosphorylation as well as the subsequent development of neurofibrillary pathology and degeneration.

    Labial hair tourniquet syndrome is a rare condition that can be easily misdiagnosed and ultimately lead to irreversible damage. An 11-year-old premenarche girl presented with a 5-day history of pain and swelling in the labia with associated vaginal discharge. The general practitioner treated her with clotrimazole without improvement. On examination, there was an oedematous swelling of the right labia with a proximal hair tourniquet. Local anaesthetic was applied and the hair removed with forceps. There was instant relief of pain and the discharge stopped within 24 h. The patient was sent home with a course of antibiotics.

    This review is on discharges maintained by travelling waves: new plasma sources, discovered in 1974 and considered as a prototype of the gas discharges according to their definition as nonlinear systems which unify in a self-consistent manner plasmas and fields. In the presentation here of the fluid-plasma models of the diffusion-controlled regime of the travelling-wave-sustained discharges (TWSDs), the basic features of the discharge maintenance-the discharge self-consistency and the electron heating in the high-frequency field-are stressed. Operation of stationary and pulsed discharges, discharge maintenance without and in external magnetic fields as well as discharge production in different gases (argon, helium, helium-argon gas mixtures and hydrogen) are covered. Modulation instability of diffusion-controlled discharges and discharge filamentation at higher gas pressures are also included in the review. Experimental findings which motivate aspects of the reported modelling are pointed out

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

    Many important gains have been made in understanding PTSD and other responses to trauma as a result of neuroscience-based observations. Yet there are many gaps in our knowledge that currently impede our ability to predict those who will develop pathologic responses. Such knowledge is essential for developing appropriate strategies for mounting a mental health response in the aftermath of terrorism and for facilitating the recovery of individuals and society. This paper reviews clinical and biological studies that have led to an identification of pathologic responses following psychological trauma, including terrorism, and highlights areas of future-research. It is important to not only determine risk factors for the development of short- and long-term mental health responses to terrorism, but also apply these risk factors to the prediction of such responses on an individual level. It is also critical to consider the full spectrum of responses to terrorism, as well as the interplay between biological and psychological variables that contribute to these responses. Finally, it is essential to remove the barriers to collecting data in the aftermath of trauma by creating a culture of education in which the academic community can communicate to the public what is and is not known so that survivors of trauma and terrorism will understand the value of their participation in research to the generation of useful knowledge, and by maintaining the acquisition of knowledge as a priority for the government and those involved in the immediate delivery of services in the aftermath of large-scale disaster or trauma.

    Pathological gambling creates enormous problems for the afflicted individuals, their families, employers, and society, and has numerous disastrous financial consequences. The present study evaluates the financial burdens of pathological gambling by questioning pathological gamblers in treatment in Gamblers Anonymous (n=60; 56 males, 4 females; mean age = 40 years old) about personal debts, loss of productivity at work, illegal activities, medical costs and the presence of other dependencies. Results show that important debts, loss of productivity at work and legal problems are associated with pathological gambling. Discussion is formulated in terms of the social cost of adopting a liberal attitude toward the legalization of various gambling activities.

  3. Forest pathology in Hawaii

    Native Hawaiian forests are characterised by a high degree of endemism, including pathogens as well as their hosts. With the exceptions of koa (Acacia koa Gray), possibly maile (Alyxia oliviformis Gaud.), and, in the past, sandalwood (Santalum spp.), forest species are of little commercial value. On the other hand, these forests are immensely important from a cultural, ecological, and evolutionary standpoint. Forest disease research was lacking during the mid-twentieth century, but increased markedly with the recognition of ohia (Metrosideros polymorpha Gaud.) decline in the 1970s. Because many pathogens are themselves endemic, or are assumed to be, having evolved with their hosts, research emphasis in natural areas is on understanding host-parasite interactions and evolutionary influences, rather than disease control. Aside from management of native forests, attempts at establishing a commercial forest industry have included importation of several species of pine, Araucaria, and Eucalyptus as timber crops, and of numerous ornamentals. Diseases of these species have been introduced with their hosts. The attacking of native species by introduced pathogens is problematic - for example, Armillaria mellea (Vahl ex Fr.) Que??l. on koa and mamane (Sophora chrysophylla (Salisb.) Seem.). Much work remains to be done in both native and commercial aspects of Hawaiian forest pathology.

    Fifteen volunteers and 73 patients with suspected rotator cuff lesions were examined at 0.5 T with T2 * -weighted gradient-echo (GE) MR imaging (700/33/30 degrees) (oblique coronal and sagittal 3 mm thick, surface coil). Results were compared with those of arthrography (all cases), T1-weighted GE imaging (400/20/90 degrees) (35 cases), surgery (28 cases), and T2-weighted spin-echo (SE) images (2,000/60-120) (17 cases). GE images demonstrated all tears (complete, 32, partial, 12) and was superior to arthrography in determining site and size and in displaying muscles (critical point in surgical planning). In 20 cases without tears on arthrography, GE imaging demonstrated five cases of tendinitis, five cases of bursitis, and six probable intratendinous or superficial partial tears. T2 * -weighted GE imaging was superior to T2-weighted SE and T1-weighted GE imaging, with higher fluid contrast and a low fat signal. Therefore, it might replace arthrography in the diagnosis and surgical approach to this pathology

    Primary syphilis caused by Treponema pallidum usually develops after sexual contact as an initial solitary sclerosis or hard chancre in the genital region. We describe a case of primary syphilis at three sites in genital and extragenital regions of a man who had sex with men. A 29-year-old man visited our hospital for skin lesions on his lower lip, nipple-areola and penis. A positive syphilis serological test for rapid plasma reagin had a titer of 1:16; the patient also tested positive for specific antibodies against T. pallidum, with a cut-off index of 39.0. Histopathological examination of a nipple-areola biopsy specimen revealed a thickened epidermis and dense infiltration of inflammatory cells extending from the upper dermal layers to the deep dermis. The inflammatory cells were composed of abundant lymphocytes, plasma cells, histiocytes and neutrophils. Immunohistochemical staining for T. pallidum using an anti-T. pallidum antibody showed numerous spirochetes in the lower portion of the epidermis, scattered inside inflammatory cell infiltrate and perivascular sites throughout the dermis. Based on these findings, the patient was diagnosed with primary syphilis. Treatment with oral amoxicillin hydrate was started. Five days after starting treatment, a diffuse maculopapular rash (syphilitic roseola) occurred on his trunk and extremities. Perivascular cuffing due to T. pallidum was present throughout the dermis in the biopsy specimen of a localized lesion of primary syphilis. Moreover, syphilitic roseola, which indicates generalized dissemination of T. pallidum, developed during the course of treatment for primary syphilis. Therefore, we considered perivascular cuffing to be indicative of the dissemination phase. © 2015 Japanese Dermatological Association.

    Full Text Available Sphingolipids are components of the lipid rafts in plasma membranes, which are important for proper function of podocytes, a key element of the glomerular filtration barrier. Research revealed an essential role of sphingolipids and sphingolipid metabolites in glomerular disorders of genetic and non-genetic origin. The discovery that glucocerebrosides accumulate in Gaucher disease in glomerular cells and are associated with clinical proteinuria initiated intensive research into the function of other sphingolipids in glomerular disorders. The accumulation of sphingolipids in other genetic diseases including Tay-Sachs, Sandhoff, Fabry, hereditary inclusion body myopathy 2, Niemann-Pick and nephrotic syndrome of the Finnish type and its implications with respect to glomerular pathology will be discussed. Similarily, sphingolipid accumulation occurs in glomerular diseases of non-genetic origin including diabetic kidney disease (DKD, HIV-associated nephropathy, focal segmental glomerulosclerosis (FSGS and lupus nephritis. Sphingomyelin metabolites, such as ceramide, sphingosine and sphingosine-1-phosphate have also gained tremendous interest. We recently described that sphingomyelin phosphodiesterase acid-like 3b (SMPDL3b is expressed in podocytes where it modulates acid sphingomyelinase (ASMase activity and acts as a master modulator of danger signaling. Decreased SMPDL3b expression in post-reperfusion kidney biopsies from transplant recipients with idiopathic FSGS correlates with the recurrence of proteinuria in patients and in experimental models of xenotransplantation. Increased SMPDL3b expression is associated with DKD. The consequences of differential SMPDL3b expression in podocytes in these diseases with respect to their pathogenesis will be discussed. Finally, the role of sphingolipids in the formation of lipid rafts in podocytes and their contribution to the maintenance of a functional slit diaphragm in the glomerulus will be discussed.

    As one of the most important steps in wastewater treatment, limited study on plasma discharge process is a key challenge in the development of plasma applications. In this study, we focus on the plasma discharge process of a pulsed diaphragm discharge system. According to the analysis, the pulsed diaphragm discharge proceeds in seven stages: (1) Joule heating and heat exchange stage; (2) nucleated site formation; (3) plasma generation (initiation of the breakdown stage); (4) avalanche growth and plasma expansion; (5) plasma contraction; (6) termination of the plasma discharge; and (7) heat exchange stage. From this analysis, a critical voltage criterion for breakdown is obtained. We anticipate this finding will provide guidance for a better application of plasma discharges, especially diaphragm plasma discharges.

    1998-11-01

    In November of 1993, mysterious signals recorded by a satellite-borne broadband VHF radio science experiment called Blackboard led to a completely unexpected discovery. Prior to launch of the ALEXIS satellite, it was thought that its secondary payload, Blackboard, would most often detect the radio emissions from lightning when its receiver was not overwhelmed by noise from narrowband communication carriers. Instead, the vast majority of events that triggered the instrument were isolated pairs of pulses that were one hundred times more energetic than normal thunderstorm electrical emissions. The events, which came to be known as TIPPs (for transionospheric pulse pairs), presented a true mystery to the geophysics community. At the time, it was not even known whether the events had natural or anthropogenic origins. After two and one half years of research into the unique signals, two ground-based receiver arrays in New Mexico first began to detect and record thunderstorm radio emissions that were consistent with the Blackboard observations. On two occasions, the ground-based systems and Blackboard even recorded emissions that were produced by the same exact events. From the ground based observations, it has been determined that TIPP events areproduced by brief, singular, isolated, intracloud electrical discharges that occur in intense regions of thunderstorms. These discharges have been dubbed CIDS, an acronym for compact intracloud discharges. During the summer of 1996, ground-based receiver arrays were used to record the electric field change signals and broadband HF emissions from hundreds of CIDS. Event timing that was accurate to within a few microseconds made possible the determination of source locations using methods of differential time of arrival. Ionospheric reflections of signals were recorded in addition to groundwave/line-of-sight signals and were used to determine accurate altitudes for the discharges. Twenty-four CIDS were recorded from three

    Z-pinches formed from frozen deuterium fibers by a rapidly rising current have enhanced stability and high neutron yield. The efforts to understand the enhanced stability and neutron yield on the basis of classical picture of Bennett equilibrium of the current channel has not given satisfactory results. The traditional approach does not take into account the essential difference between the frozen deuterium fiber Z-pinches and the usual Z-pinches such as exploding wires or classical gas-puffed Z-pinches. The very low temperature of the fiber atoms (10 K), together with the rapidly rising current, result in the coexistence of a high current channel with unionized fiber atoms for a substantial period of time. This phenomena lasts during the risetime. This approach takes into account the difference of the breakdown in a dielectric deuterium fiber and the breakdown in a metallic wire. This difference is essential to the understanding of specific features of cryogenic high current discharges. Z-pinches in frozen deuterium fibers should be considered as a qualitatively new phenomenon on the boundary of cryogenic and high current physics. It is a start of a new branch in plasma physics: the physics of cryogenic high current discharges

    2014-01-01

    There is relatively little published literature concerning utilization management in anatomic pathology. Nonetheless there are many utilization management opportunities that currently exist and are well recognized. Some of these impact only the cost structure within the pathology department itself whereas others reduce charges for third party payers. Utilization management may result in medical legal liabilities for breaching the standard of care. For this reason it will be important for pathology professional societies to develop national utilization guidelines to assist individual practices in implementing a medically sound approach to utilization management. © 2013.

    Thermal and nuclear power stations in Japan are mostly located in coastal area, and the cooling water is discharged into sea as warm water. Recently, large interest is taken in this matter, and it is desirable to predict the diffusion of warm discharge accurately and to take effective measures for lowering the temperature. As for the methods of predicting the diffusion of warm discharge, simplified estimation, mathematical analysis and hydrographical model experiment are used corresponding to objects and conditions. As for the measures to lower temperature, the method of discharging warm water into deep sea bottom was confirmed to be very effective. In this paper, the phenomena of diffusion of warm discharge in sea, the methods of predicting the diffusion of warm discharge, and the deep sea discharge as the measure for lowering temperature are outlined. The factors concerning the diffusion of warm discharge in sea are the conditions of discharge, topography and sea state, and the diffusion is roughly divided into mixing diffusion in the vicinity of warm water outlet and eddy diffusion in distant region. It is difficult to change artificially the conditions of diffusion in distant region, and the measures of raising the rate of dilution in near region are effective, therefore the deep sea discharge is adopted.

    Forensic odontology is the subdiscipline of dentistry which analyses dental evidence in the interest of justice. Oral pathology is the subdiscipline of dentistry that deals with the pathology affecting the oral and maxillofacial regions. This subdiscipline is utilized for identification through oral and maxillofacial pathologies with associated syndromes, enamel rod patterns, sex determination using exfoliative cytology, identification from occlusal morphology of teeth, and deoxyribonucleic acid profiling from teeth. This subdiscipline is also utilized for age estimation studies which include Gustafson's method, incremental lines of Retzius, perikymata, natal line formation in teeth, neonatal line, racemization of collagen in dentin, cemental incremental lines, thickness of the cementum, and translucency of dentin. Even though the expertise of an oral pathologist is not taken in forensic investigations, this paper aims to discuss the role of oral pathology in forensic investigation.

    Several comprehensive studies of radio frequency (rf) breakdown and rf heating are reported. They are of general interest to magnetic confinement fusion, rf linac, and high power microwave source development. The major results include: (1) a ground-breaking theory of multipactor discharge on dielectric, including a successful proof-of-principle experiment that verified the newly developed scaling laws, (2) an in depth investigation of the failure mechanisms of diamond windows and ceramic windows, and of the roles of graphitization, thin films of coating and contaminants, and (3) a most comprehensive theory, to date, on the heating of particulates by an electromagnetic pulse, and on the roles of rf magnetic field heating and of rf electric field heating, including the construction of new scaling laws that govern them. The above form a valuable knowledge base for the general problem of heating phenomenology

    According to the Section 24 of the Finnish Radiation Decree (1512/91), the Finnish Centre for Radiation and Nuclear Safety shall specify the concentration and activity limits and principles for the determination whether a waste can be defined as a radioactive waste or not. The radiation safety requirements and limits for the disposal of radioactive waste are given in the guide. They must be observed when discharging radioactive waste into the atmosphere or sewer system, or when delivering solid low-activity waste to a landfill site without a separate waste disposal plan. The guide does not apply to the radioactive waste resulting from the utilization of nuclear energy of natural resources. (4 refs., 1 tab.)

    Pathological gambling is a relatively prevalent psychiatric disorder that typically leads to severe family, social, legal, and occupational problems and is associated with a high rate of suicide attempts. Understanding the neurobiological basis of pathological gambling is a current focus of research, and emerging data have demonstrated that pathological gamblers may have impaired decision-making because of an inability to inhibit irrelevant information. In this study, we examined pathological gamblers by using the Stroop Color-Word Test, a neurocognitive task used to assess interference control. The "reverse" variant of the Stroop Color-Word Test was administered to a cohort of medication-free pathological gamblers (n=62) and a cohort of age-matched controls (n=83). In the reverse variant of the Stroop task, subjects are asked to read the meaning of the word rather than name the ink color. The reverse Stroop task was chosen because it highly discriminates ability to inhibit interference in a population of psychiatric patients. In our study, performance on the reverse Stroop task in the pathological gamblers was significantly slower and less accurate than in the healthy subjects. A new finding in our study was that for pathological gamblers, the average reaction time in the neutral condition (where the color names are displayed in black letters) was slower than the average reaction time in the incongruent condition (where the meaning of the color name and the color of the printed letters are different). This controlled study extends previous findings by showing that performance on the Stroop task is impaired in a sample of medication-free pathological gamblers.

    Symptomatic biliary disease in children and young adults requiring surgical intervention are uncommon. However even rarer is the occurrence of a spontaneous gallbladder necrosis in a child. We report a case of spontaneous necrosis in a child with no apparent causative factors. Fit and well 16 year-old boy presented with acute generalized lower abdominal pain. Examination revealed mild epigastric pain with rebound tenderness and guarding of the right iliac fossa. Diagnostic laparoscopy showed a necrotic gallbladder and incidental finding of a Meckel's diverticulum. He had a cholecystectomy and Meckel's diverticulum resection. Patient recovered uneventfully and was discharged home. He was reviewed 2 months later and recovered well with no evidence of any post-operative complication. He was discharged without any further follow up. Gall bladder necrosis is a rare cause of an acute abdomen. We present the first reported case of a spontaneous gallbladder necrosis with no apparent cause. Literature review showed various causes of gall bladder necrosis including trauma, acalculous cholecystitis, gallbladder torsion, gangrenous cholecystitis and etc. We report a case of spontaneous gallbladder necrosis in a young healthy male with no family history of thrombotic disorders or any history of sepsis, intervention, trauma and no obvious underlying anatomical or histological abnormalities. This is an exceedingly rare pathology and one would be forgiven for not including it on the list of a differential diagnosis in such circumstance. However it is important to send tissue sample to exclude any underlying histological aetiological factors. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available O uso de linhas genéticas de diferentes fontes comerciais em programas de reprodução de frangos de corte permite produzir gerações comerciais mais bem adaptadas a realidades diversas e otimizar os potenciais de desempenho do frango de corte com os da reprodutora. Entretanto, a prática predominante no Brasil é o uso de pais e mães de mesma origem. O uso de bebedouros tipo "nipple" vem sendo difundido com a perspectiva de gerar benefícios ainda não comprovados inteiramente na prática. Esse estudo avaliou a evolução dos órgãos da digestão, o desempenho vivo e o rendimento de carcaça e das partes de frangos de corte de diferentes cruzamentos entre reprodutores machos de diversos cruzamentos entre linhagens comerciais (R, I, S, e H com fêmeas também de origem variável (R, I, e H em sistemas de produção com bebedouros pendular ou nipple. As aves dos diferentes cruzamentos apresentaram curvas de crescimento com diferentes intensidades em momentos distintos, determinando desempenhos em peso vivo sempre superiores para o cruzamento RR. O rendimento de peito, entretanto, foi maior para o cruzamento IH. O cruzamento SH, de mais baixo peso corporal, evidenciou rendimentos de carcaça inferiores a todos os demais. O tipo de bebedouro não influenciou nenhum resultado de desempenho vivo ou de rendimento de carcaça, independentemente da linhagem. Os órgãos da digestão apresentaram proporções do peso vivo decrescentes com a idade, mas não evidenciaram efeito de cruzamento entre linhagens ou tipo de bebedouro.Breeding programs using parents from different genetic companies allow the production of commercial generations of broilers directed to attend diverse market situations, but they also serve to optimize the performance of the breeder female. However, this is not a current practice in Brazil where most of the commercial broilers being raised are originated from crosses within the same genetic company. The use of nipple drinkers in

    Communication is an essential element of good medical practice also in pathology. In contrast to technical or diagnostic skills, communication skills are not easy to define, teach, or assess. Rules almost do not exist. In this paper, which has a rather personal character and cannot be taken as a set of guidelines, important aspects of communication in pathology are explored. This includes what should be communicated to the pathologist on the pathology request form, communication between pathologists during internal (interpathologist) consultation, communication around frozen section diagnoses, modalities of communication of a final diagnosis, with whom and how critical and unexpected findings should be communicated, (in-)adequate routes of communication for pathology diagnoses, who will (or might) receive pathology reports, and what should be communicated and how in case of an error or a technical problem. An earlier more formal description of what the responsibilities are of a pathologist as communicator and as collaborator in a medical team is added in separate tables. The intention of the paper is to stimulate reflection and discussion rather than to formulate strict rules.

    Throughout the course of history, gambling has been a popular activity across most cultures. In the United States, gambling has transitioned from early acceptance to prohibition to widespread proliferation. For most, gambling is a relaxing and recreational activity; however, for some individuals gambling becomes more than harmless fun. The most severe form of gambling, pathological gambling, is recognized as a mental health disorder. Pathological gambling is currently classified as an impulse control disorder in the DSM-IV-TR, but it shares many important features with substance use disorders, especially in terms of diagnostic criteria, clinical course, and treatment. Consequently, the DSM-V Task Force has suggested that pathological gambling be reclassified and included in a new category entitled "Addiction and Related Disorders." The category would include both substance-related and non-substance/behavioral addictions. This article provides a general overview of some of the available literature regarding pathological gambling and includes the presentation of a number of relevant topics including etiology, risk factors, comorbidity, prevention, and treatment. However, as with most complex, multifaceted, and multidimensional phenomena, more research is needed in order to improve both prevention and treatment efforts for pathological gambling.

  14. Discharge cleaning for a tokamak

    1983-01-01

    Various methods of discharge cleaning for tokamaks are described. The material of the first walls of tokamaks is usually stainless steel, inconel, titanium and so on. Hydrogen is exclusively used as the discharge gas. Glow discharge cleaning (GDC), Taylor discharge cleaning (TDC), and electron cyclotron resonance discharge cleaning (ECR-DC) are discussed in this paper. The cleaning by GDC is made by moving a movable anode to the center of a tokamak vassel. Taylor found the good cleaning effect of induced discharge by high pressure and low power discharge. This is called TDC. When the frequency of high frequency discharge in a magnetic field is equal to that of the electron cyclotron resonance, the break down potential is lowered if the pressure is sufficiently low. The ECR-CD is made by using this effect. In TDC and ECR-DC, the electron temperature, which has a close relation to the production rate of H 0 , can be controlled by the pressure. In GDC, the operating pressure was improved by the radio frequency glow (RG) method. However, there is still the danger of arcing. In case of GDC and ECR-DC, the position of plasma can be controlled, but not in case of TDC. The TDC is accepted by most of takamak devices in the world. (Kato, T.)

    Imaging breasts with a short chest wall to nipple distance (CWND) using a traditional mammographic X-ray unit is a technical challenge for mammographers. The purpose of this study is the development of an imaging-planning program to assist in determination of imaging parameters of screen/film (SF) and computed radiography (CR) mammography for short CWND breasts. A traditional mammographic X-ray unit (Mammomat 3000, Siemens, Munich, Germany) was employed. The imaging-planning program was developed by combining the compressed breast thickness correction, the equivalent polymethylmethacrylate thickness assessment for breasts and the tube loading (mAs) measurement. Both phantom exposures and a total of 597 exposures were used for examining the imaging-planning program. Results of the phantom study show that the tube loading rapidly decreased with the CWND when the automatic exposure control (AEC) detector was not fully covered by the phantom. For patient exposures with the AEC fully covered by breast tissue, the average fractional tube loadings, defined as the ratio of the predicted mAs using the imaging-planning program and mAs of the mammogram, were 1.10 and 1.07 for SF and CR mammograms, respectively. The predicted mAs values were comparable to the mAs values, as determined by the AEC. By applying the imaging-planning program in clinical practice, the experiential dependence of the mammographer for determination of the imaging parameters for short CWND breasts is minimised.

    'Terminal discharges' are carried out in Singapore for patients who wish to die at home. However, if due diligence is not exercised, parallels may be drawn with euthanasia. We present a theoretical discussion beginning with the definition of terminal discharges and the reasons why they are carried out in Singapore. By considering the intention behind terminal discharges and utilising a multidisciplinary team to deliberate on the clinical, social and ethical intricacies with a patient- and context-specific approach, euthanasia is avoided. It is hoped that this will provide a platform for professionals in palliative medicine to negotiate challenging issues when arranging a terminal discharge, so as to avoid the pitfall of committing euthanasia in a country such as Singapore where euthanasia is illegal. It is hoped that a set of guidelines for terminal discharges may someday be realised to assist professionals in Singapore and around the world.

    ASDEX Upgrade's recently commissioned discharge control system (DCS) marks the transition from a traditional programmed system to a highly flexible 'data driven' one. The allocation of application processes (APs) to controllers, the interconnection of APs through uniquely named signals, and AP control parameter values are all defined as data, and can easily be adapted to the requirements of a particular discharge. The data is laid down in a set of XML documents which APs request via HTTP from a configuration server before a discharge. The use of XML allows for easy parsing, and structural validation through (XSD) schemas. The central input to the configuration process is the discharge schedule (DS), which embodies the dynamic behaviour of a planned discharge as reference trajectories grouped in segments, concatenated through transition conditions. Editing, generation and validation tools, and version control through CVS allow for efficient management of DSs

    2008-04-01

    Oral ulceration has many causes and is a common presenting symptom in otolaryngology. This article presents an unusual case of dual pathology oral ulceration in an elderly patient. Oral malignancy was initially suspected, but the history, examination and investigation showed that the oral ulceration was caused by actinomycosis infection and by nicorandil use. Cervicofacial acinomycosis is a rare, suppurative bacterial disease in which abscesses can form in the tissues and break through the skin, creating pus-discharging lesions. Nicorandil is a potassium channel blocker used in the treatment of ischaemic heart disease. It has been recently recognised as a cause of persistent ulcerative stomatitis. This case highlights the importance of a high index of suspicion for unusual and reversible causes of oral ulceration, and of dual pathology as a cause. Such vigilance enables early recognition and treatment of potentially reversible conditions.

    2017-11-01

    In this review, we will discuss (i) how the recent advancements in digital technology and computational engineering are currently applied to nephropathology in the setting of clinical research, trials, and practice; (ii) the benefits of the new digital environment; (iii) how recognizing its challenges provides opportunities for transformation; and (iv) nephropathology in the upcoming era of kidney precision and predictive medicine. Recent studies highlighted how new standardized protocols facilitate the harmonization of digital pathology database infrastructure and morphologic, morphometric, and computer-aided quantitative analyses. Digital pathology enables robust protocols for clinical trials and research, with the potential to identify previously underused or unrecognized clinically useful parameters. The integration of digital pathology with molecular signatures is leading the way to establishing clinically relevant morpho-omic taxonomies of renal diseases. The introduction of digital pathology in clinical research and trials, and the progressive implementation of the modern software ecosystem, opens opportunities for the development of new predictive diagnostic paradigms and computer-aided algorithms, transforming the practice of renal disease into a modern computational science.

    Background Chronically ill people experience frequent changes in health status accompanied by multiple transitions between care settings and care providers. Discharge planning provides support services, follow-up activities, and other interventions that span pre-hospital discharge to post-hospital settings. Objective To determine if discharge planning is effective at reducing health resource utilization and improving patient outcomes compared with standard care alone. Data Sources A standard systematic literature search was conducted for studies published from January 1, 2004, until December 13, 2011. Review Methods Reports, randomized controlled trials, systematic reviews, and meta-analyses with 1 month or more of follow-up and limited to specified chronic conditions were examined. Outcomes included mortality/survival, readmissions and emergency department (ED) visits, hospital length of stay (LOS), health-related quality of life (HRQOL), and patient satisfaction. Results One meta-analysis compared individualized discharge planning to usual care and found a significant reduction in readmissions favouring individualized discharge planning. A second meta-analysis compared comprehensive discharge planning with postdischarge support to usual care. There was a significant reduction in readmissions favouring discharge planning with postdischarge support. However, there was significant statistical heterogeneity. For both meta-analyses there was a nonsignificant reduction in mortality between the study arms. Limitations There was difficulty in distinguishing the relative contribution of each element within the terms “discharge planning” and “postdischarge support.” For most studies, “usual care” was not explicitly described. Conclusions Compared with usual care, there was moderate quality evidence that individualized discharge planning is more effective at reducing readmissions or hospital LOS but not mortality, and very low quality evidence that it is more

    Childhood vaginal discharge remains a frequent reason for referral from primary to secondary care. The Pediatric and Adolescent Gynecology (PAG) service at Kettering General Hospital was established in 1993 and provides a specialized service that meets the needs of children with gynaecological conditions. To investigate recurrent vaginal discharge noting symptomatology, defining pathogens, common and rarer causes, exploring management regimes, and any changes in practice over time. Retrospective review spanning 15 years identifying prepubertal children attending the outpatient PAG clinic with recurrent vaginal discharge. We reviewed the medical notes individually. 110 patients were identified; 85% were referred from primary care. The age distribution was bimodal at four and eight years. Thirty-five percent of our patients were discharged after the initial consultation. The commonest cause of discharge was vulvovaginitis (82%). Other important causes included suspected sexual abuse (5%), foreign body (3%), labial adhesions (3%), vaginal agenesis (2%). 35% of patients were admitted for vaginoscopy. Vaginal discharge is the most common gynecological symptom in prepubertal girls and can cause repeated clinical episodes. Vulvovaginitis is the most common cause and often responds to simple hygiene measures. Awareness of the less common causes of vaginal discharge is essential.

    An overview of those legal areas which directly affect technical and planning decisions is presented in the form of 2 legal approaches which constrain the indiscriminate release of thermal discharges to receiving waters. One takes the form of private remedies which have traditionally been available to aggrieved parties who are in some way damaged by the harmful discharge. The 2nd approach utilizes the various statutory constraints leading to direct governmental action. It appears that statutory law is playing the prominent role in restricting the temperature to which receiving waters may be raised as a result of such discharges by using effluent limitations and water quality standards.

    A new scheme of ion source based on a dielectric surface sliding discharge is described. The conditions to form this type of discharge are analyzed and experimental results are shown. The main parameters of this ion source are: accelerating voltage U = 1/20kV; continuous extracted ion beam; current density j = 0.01/0.5 A/cm 2 ; ions of Cl, F, C, H; residual gas pressure P = 10 -6 Torr. A magnetic system is used to separate the different types of ions. The dielectric material in the discharge circuit (anode plasma emitter) defines the type of ions. The emission characteristics of plasma emitter and the discharge parameters are presented. The ion current yield satisfies the Child-Langmuir law. (author)

    Conditions under which ballooning modes are expected to be excited have recently been obtained in two different types of discharges in JET. In the first type, extremely large pressure gradients have been produced in the plasma core through pellet injections in the current rise phase followed by strong additional heating. In the second type, the total pressure of the discharge is approaching the Troyon limit. The stability of these discharges with respect to the ideal MHD ballooning modes has been studied with the stability code HBT. The equilibria are reconstructed with the IDENTC code using the external magnetic measurements and the experimental pressure profile. The results show that the evaluated high beta discharge is unstable in the central region of the plasma. This instability is related to the low shear and not to a large pressure gradient, as expected at the Troyon limit. In the pellet discharges the regions with the large pressure gradients are unstable to ballooning modes at the time of the beta decay, which ends the period of enhanced performance. The maximum pressure gradient in these discharges is limited by the boundary of the first region of stability. The observed phenomena at the beta decay are similar to those observed at the beta limit in DIII-D and TFTR. (author)

  17. Filamentary and diffuse barrier discharges

    International Nuclear Information System (INIS)

    Kogelschatz, U.

    2001-01-01

    Barrier discharges, sometimes also referred to as dielectric-barrier discharges or silent discharges, are characterized by the presence of at least one insulating layer in contact with the discharge between two planar or cylindrical electrodes connected to an ac power supply. The main advantage of this type of electrical discharge is, that non-equilibrium plasma conditions in atmospheric-pressure gases can be established in an economic and reliable way. This has led to a number of important applications including industrial ozone generation, surface modification of polymers, plasma chemical vapor deposition, excitation of CO 2 lasers, excimer lamps and, most recently, large-area flat plasma display panels. Depending on the application, the width of the discharge gap can range from less than 0.1 mm to about 100 mm and the applied frequency from below line frequency to several gigahertz. Typical materials used for the insulating layer (dielectric barrier) are glass, quartz, ceramics but also thin enamel or polymer layers

    While obesity is a known risk factor for postmenopausal breast cancer, the molecular mechanisms involved are unclear. Systemic levels of leptin, the product of the ob (obesity) gene, are increased in obese individuals (body mass index, BMI, over 25) and are higher in women than men. Leptin has been found to stimulate the growth of breast cancer cells in vitro. Our goal was to determine whether leptin was 1) present in nipple aspirate fluid (NAF), and 2) whether NAF leptin levels were associated with a) levels in serum, b) obesity, and c) breast cancer. We collected and evaluated NAF specimens from 83 subjects and serum specimens from 49 subjects. NAF leptin was detectable in 16/41 (39 %) of premenopausal and 21/42 (50 %) postmenopausal subjects. NAF leptin was significantly lower (p = 0.042) in premenopausal than postmenopausal women with a BMI < 25, but not in those with a higher BMI. NAF leptin was significantly associated with BMI in premenopausal (p = 0.011) but not in postmenopausal women. Serum leptin was associated with BMI in both premenopausal and postmenopausal women (p = 0.0001 for both). NAF and serum leptin were associated in premenopausal (p = 0.02) but not postmenopausal women. Neither NAF nor serum leptin was associated with premenopausal or postmenopausal breast cancer. Our findings include that 1) leptin is present in the breast and detectable in a subset of NAF samples, 2) NAF leptin in premenopausal but not postmenopausal women parallels serum leptin levels, and 3) neither NAF nor serum levels of leptin were associated with premenopausal or postmenopausal breast cancer.

    Reconstruction options following nipple-sparing mastectomy (NSM) are diverse and not yet investigated with level IA evidence. The analysis of surgical and oncological outcomes of NSM from the Italian National Registry shows its safety and wide acceptance both for prophylactic and therapeutic cases. A further in-depth analysis of the reconstructive approaches with their trend over time and their failures is the aim of this study. Data extraction from the National Database was performed restricting cases to the 2009-2014 period. Different reconstruction procedures were analyzed in terms of their distribution over time and with respect to specific indications. A 1-year minimum follow-up was conducted to assess reconstructive unsuccessful events. Univariate and multivariate analyses were performed to investigate the causes of both prosthetic and autologous failures. 913 patients, for a total of 1006 procedures, are included in the analysis. A prosthetic only reconstruction is accomplished in 92.2 % of cases, while pure autologous tissues are employed in 4.2 % and a hybrid (prosthetic plus autologous) in 3.6 %. Direct-to-implant (DTI) reaches 48.7 % of all reconstructions in the year 2014. Prophylactic NSMs have a DTI reconstruction in 35.6 % of cases and an autologous tissue flap in 12.9 % of cases. Failures are 2.7 % overall: 0 % in pure autologous flaps and 9.1 % in hybrid cases. Significant risk factors for failures are diabetes and the previous radiation therapy on the operated breast. Reconstruction following NSM is mostly prosthetic in Italy, with DTI gaining large acceptance over time. Failures are low and occurring in diabetic and irradiated patients at the multivariate analysis.

    The nipple-areolar complex (NAC) has special histological properties with higher melanocyte concentration than breast skin. To date, there are no data describing the late effects on the NAC following breast-conserving therapy (BCT). This study evaluated colour changes in the NAC in patients treated with breast-conserving surgery and adjuvant radiotherapy after 5 years. Digital photographs obtained at 5 years following breast irradiation from the St. George and Wollongong (SGW) trial (NCT00138814) were evaluated by five experts using an iPad® (Apple Inc., Cupertino, CA, USA) application specifically created for this study. The SGW trial randomised 688 patients with Tis-2, N0-1, M0 carcinoma to the control arm of 50Gy in 25 fractions and boost arm of 45Gy in 25 fractions and 16 Gy in 8 fractions electron boost. A total of 141/372 (38%) patients had altered NAC (86% lighter, 10% darker). Patients with Celtic skin type had increased likelihood of having an altered NAC (odds ratio (OR), 1.75 (CI 1.1–2.7, P=0.011)). On subgroup analysis, those with Celtic skin type receiving biologically equivalent dose (BED) Gy3 ≥ 80Gy had OR of 3.03 (95% CI 1.2–7.5, P=0.016) for having altered colour. There was a dose response with more profound changes seen in the NAC compared with irradiated breast skin if BED Gy3 ≥ 80Gy with OR of 2.42 (95% CI 1.1–5.6, P=0.036). In this Caucasian BCT population, over 30% of patients developed lighter NAC and more commonly in women with Celtic skin type. The degree of this effect increased with higher radiation dose.

    2003-01-01

    The teaching environment for plant pathology is changing in both positive and negative ways. Teaching expectations are increasing and resources are decreasing, but recent educational research and instructional technology offer new approaches to meet these challenges. Plant pathologists are teaching courses that may attract new students to the discipline or at least improve agricultural awareness. The Internet offers rapid access to information and images for both students and instructors. Instructional technology provides new tools for classroom presentations, communication with students, reaching new audiences, and distance learning, but using these new tools to enhance learning requires skilled and creative instructors. In the past, many plant pathology instructors worked in relative isolation, but new communication technologies and publishing opportunities for teaching scholarship should improve the sharing of instructional resources and methods.

  3. Radioisotope studies under pathologic conditions

    1987-01-01

    This article presents a general discussion on salivary pathology, before dealing with the various salivary gland diseases which can draw real advantage from radioisotope studies. Clinical problems related to the salivary glands first concern diffuse or focal glandular swelling. Focal swelling includes inflammatory or metastatic deposits in preauricular or submandibular lymph nodes, cysts, abscesses, foci of inflammation, benign and malignant neoplasms of the salivary glands themselves or of surrounding blood or lymph vessels, nerves, connective tissue, and oral mucosa. Primary tumors of the salivary glands are rare and usually benign. The combination of a systemic disease with dry mouth and dry eyes due to inflamed conjunctiva and cornea because of decreased fluid production, forms Sjogren syndrome. It may also cause diffuse glandular swelling. Chronic alcoholism, cirrhosis, diabetes mellitus, hyperlipoproteinemia, and malnutrition are other pathologic conditions sometimes associated with diffuse salivary gland swelling

  4. Quality in pathology laboratory practice.

    Science.gov (United States)

    Weinstein, S

    1995-06-01

    Quality refers not only to analytical quality control, a traditional area of laboratory excellence, but to the entire science of quality management. As measures of quality, structural indicators refer to staffing and physical facilities, process indicators to the institutions operations and, perhaps most importantly, outcome indicators address the ultimate patient care uses that pathology information is put to. Comparison of performance to peer laboratories, external quality control, is a practical, if limited, yardstick of performance. Customer satisfaction and turn-around-time of tests are receiving more recent attention as quality measures. Blood banking, because of its inherently complex cycle from donor phlebotomy to product infusion, requires special considerations with regard to quality management. Reporting of anatomical pathology, where the only gold standard is a consensus of experts, also does not lend itself to classical numerical quality assessment.

    Interleukin-22 (IL-22) is a recently described IL-10 family cytokine that is produced by T-helper (Th)-17 cells, γδ T cells, NKT cells and newly described innate lymphoid cells (ILCs). Knowledge of IL-22 biology has rapidly evolved since its discovery in 2000, and a role for IL-22 has been identified in numerous tissues including the intestines, lung, liver, kidney, thymus, pancreas and skin. IL-22 primarily targets non-hematopoietic epithelial and stromal cells where it can promote proliferation and play a role in tissue regeneration. In addition, IL-22 regulates host defense at barrier surfaces. However, IL-22 has also been linked to several conditions involving inflammatory tissue pathology. In this review, we will assess the current understanding of this cytokine, including its physiologic and pathologic effects on epithelial cell function. PMID:25706098

NFT pathology is important since it correlates with the degree of cognitive impairment in AD.Only a small proportion of AD is due to genetic variants, whereas the large majority of cases (~99% is late onset and sporadic in origin. The cause of sporadic AD is likely to be multifactorial, with external factors interacting with biological or genetic susceptibilities to accelerate the manifestation of the disease.Insulin dysfunction, manifested by diabetes mellitus (DM might be such factor, as there is extensive data from epidemiological studies suggesting that DM is associated with an increased relative risk for AD. Type 1 diabetes (T1DM and type 2 diabetes (T2DM are known to affect multiple cognitive functions in patients. In this context, understanding the effects of diabetes on Tau pathogenesis is important since tau pathology show a strong relationship to dementia in AD, and to memory loss in normal aging and mild cognitive impairment.Here, we reviewed preclinical studies that link insulin dysfunction to Tau protein pathogenesis, one of the major pathological hallmarks of AD. We found more than 30 studies reporting on Tau phosphorylation in a mouse or rat model of insulin dysfunction. We also payed attention to potential sources of artifacts, such as hypothermia and anesthesia, that were demonstrated to results in Tau hyperphosphorylation and could major confounding experimental factors. We found that very few studies reported the temperature of the animals, and only a handful did not use anesthesia. Overall, most published studies showed that insulin dysfunction can promote Tau hyperphosphorylation and pathology, both directly and indirectly, through hypothermia.

    Controlled electrical discharge aids in conditioning of the system while uncontrolled discharges damage its electronic components. DC Accelerator being a high voltage system is no exception. It is useful to classify electrical discharges according to the severity. Experimental prototypes of the accelerator discharges are developed. Photomultiplier Tubes (PMTs) are used to detect the signals from these discharges. Time and Frequency domain characteristics of the detected discharges are used to extract features. Machine Learning approaches like Fuzzy Logic, Neural Network and Least Squares Support Vector Machine (LSSVM) are employed to classify the discharges. This aids in detecting the severity of the discharges.

  12. Pathological Jealousy: An Interactive Condition.

    Seeman, Mary V

    2016-01-01

    The aim of this review is to describe the psychopathology, antecedents, and current management of pathological jealousy from an interpersonal perspective. The Google Scholar database was searched with the following terms: delusional jealousy; morbid jealousy; paranoid jealousy; pathological jealousy; Othello syndrome; delusional disorder-jealous type; conjugal paranoia. From a total of 600 articles, 40 were selected based on their currency and pertinence to the interpersonal aspects of jealousy. Findings were that delusional jealousy is equally prevalent among men and women, with a greater prevalence in the elderly. Antecedents to this condition can be neurologic, drug related, and/or psychological, most often preceded by low self-esteem and excessive dependence on a romantic partner. Pathological jealousy can be triggered by the behavior of the partner and maintained by reasoning biases and by the psychological benefits that it initially bestows on the relationship. In the long run, however, it poses dangerous risks to the patient, the partner, and the imagined rival so that involuntary hospitalization is sometimes required. Treatment recommendations include couple therapy, a strong cognitive focus, antipsychotic medication, and interventions which enhance self-esteem of both partners and which address the solidarity of the existing relationship. Treatment effectiveness does not yet have a firm evidence base.

    Medical records of all prepubertal patients who underwent vaginoscopy to rule out vaginal foreign body between 2004 and 2013 were reviewed retrospectively. All patients were evaluated by pediatricians prior to surgical consultation. Vaginoscopy is performed in the operating room under general anesthesia. During the study period, 20 girls with persistent vaginal discharge with a mean age of 6.8 years (1-13 years) underwent vaginoscopy to rule out vaginal foreign body. Six patients had bloody vaginal discharge and 4 had recurrent vaginal bleeding lasting for more than one month. Ten patients had purulent vaginal discharge lasting for 1-7 months. None of vaginal cultures revealed pathological bacteria or candida species. Preoperative imaging techniques revealed vaginal foreign body in one patient only. Vaginoscopy demonstrated vaginal foreign bodies in four patients. Foreign bodies were grass inflorescence, safety pin and undefined brownish particles (n=2), which may be pieces of toilet paper or feces. There was no complication related to vaginoscopy and removal of foreign body. Hymen integrity was preserved in all patients. Persistent or recurrent vaginal discharge in prepubertal girls should raise the suspect of vaginal foreign body. Continuous flow vaginoscopy is mandatory to detect and remove any vaginal foreign body. Early diagnosis would prevent complications secondary to long-standing foreign bodies.

  14. Estimating sediment discharge: Appendix D

    Gray, John R.; Simões, Francisco J. M.

    2008-01-01

    Sediment-discharge measurements usually are available on a discrete or periodic basis. However, estimates of sediment transport often are needed for unmeasured periods, such as when daily or annual sediment-discharge values are sought, or when estimates of transport rates for unmeasured or hypothetical flows are required. Selected methods for estimating suspended-sediment, bed-load, bed- material-load, and total-load discharges have been presented in some detail elsewhere in this volume. The purposes of this contribution are to present some limitations and potential pitfalls associated with obtaining and using the requisite data and equations to estimate sediment discharges and to provide guidance for selecting appropriate estimating equations. Records of sediment discharge are derived from data collected with sufficient frequency to obtain reliable estimates for the computational interval and period. Most sediment- discharge records are computed at daily or annual intervals based on periodically collected data, although some partial records represent discrete or seasonal intervals such as those for flood periods. The method used to calculate sediment- discharge records is dependent on the types and frequency of available data. Records for suspended-sediment discharge computed by methods described by Porterfield (1972) are most prevalent, in part because measurement protocols and computational techniques are well established and because suspended sediment composes the bulk of sediment dis- charges for many rivers. Discharge records for bed load, total load, or in some cases bed-material load plus wash load are less common. Reliable estimation of sediment discharges presupposes that the data on which the estimates are based are comparable and reliable. Unfortunately, data describing a selected characteristic of sediment were not necessarily derived—collected, processed, analyzed, or interpreted—in a consistent manner. For example, bed-load data collected with

    Currently, there is no experimental data on the plasma balance in gas mixtures with a high content of singlet delta oxygen O 2 ( 1 Δ g ). These data can be obtained by studying the parameters of an electric discharge in singlet oxygen produced by a chemical generator. The O 2 ( 1 Δ g ) molecules significantly change the kinetics of electrons and negative ions in plasma. Hence, the discharge conditions at low and high O 2 ( 1 Δ g ) concentrations are very different. Here, the parameters of the positive column of a glow discharge in a gas flow from a chemical singlet-oxygen generator are studied. It is experimentally shown that, at an O 2 ( 1 Δ g ) concentration of 50% and at pressures of 1.5 and 2 torr, the electric field required to sustain the discharge is considerably lower than in the case when all of the oxygen molecules are in the ground state. A theoretical model of the glow discharge is proposed whose predictions are in good agreement with the experimental data

  20. Electron runaway in rf discharges

    International Nuclear Information System (INIS)

    Chen, F.F.

    1992-10-01

    The critical electric field is computed as a function of pressure and starting energy for electrons to run away to high energies in moderate pressure discharges. The runaway conditions depend critically on the shape of the elastic cross section vs. energy curve. Computations are made for H, H 2 , and He gases, and it is shown that runaway occurs much more readily in atomic hydrogen than in the other gases. The values of the runaway fields are larger than would normally occur in dc discharges, where large voltages would lead to arc formation. However, in rf discharges such electric fields can be sustained over times long compared to electron transit times but short compared to ion transit times. (author)

    A circuit for quenching discharges in gas-discharge detectors with working voltage of 3-5 kV based on transistors operating in the avalanche mode is described. The quenching circuit consists of a coordinating emitter follower, amplifier-shaper for avalanche key cascade control which changes potential on the counter electrodes and a shaper of discharge quenching duration. The emitter follower is assembled according to a widely used flowsheet with two transistors. The circuit permits to obtain a rectangular quenching pulse with front of 100 ns and an amplitude of up to 3.2 kV at duration of 500 μm-8 ms. Application of the quenching circuit described permits to obtain countering characteristics with the slope less than or equal to 0.02%/V and plateau extent greater than or equal to 300 V [ru

  4. Ethics and Professionalism in Pathology

    Full Text Available Pathologists spend most of their professional lives beyond direct view of the public, mostly inside the four walls of the lab. It is the clinicians who face the wrath of the public when something goes wrong. However, with the growing awareness of the public into the decisive role played by the Pathologists in the definitive diagnosis of the disease, the pathologists will soon be the target of the aggrieved patients and relatives.1 The issue of ethics can be dealt when professionalism comes before profession. "Professionalism in medicine requires that physician serve the interests of the patient above his or her own selfinterest." Professionalism aspires to philanthropy, answerability, excellence, duty, service and respect for others. "Professionalism in Pathology is based on the same tenets, but has additional dimensions."The qualities of professionalism for pathologists include 1. Communication with the patients and the clinicians. A small phone call with the clinician will solve most of the clinical mysteries not written in the lab requisition forms; 2. Empathy and Compassion towards patients', colleagues', and laboratory personnel's culture, age, gender, and disabilities; 3. Demonstration of passion, respect and understanding towards the patients; 4. Adherence to guidelines and regulations of the regulatory and accrediting bodies; and 5.Profeciency and knowledge in one's work is valued by the patients more than the credentials, which also enables one to identify deficiencies in peer performance. The basic competencies of professionalism are vital to every pathology report, which in turn is the mirror of the ethics practiced by the pathologist. Evaluating oneself is perhaps the most important tool in maintaining professionalism in the practice of pathology. One colleague recently defined professionalism as “all the things one does when no one is watching,” thus placing personal integrity at the top of the list.

  5. State Waste Discharge Permit application, 183-N Backwash Discharge Pond

    1994-06-01

    As part of the Hanford Federal Facility Agreement and Consent Order negotiations (Ecology et al. 1994), the US Department of Energy, Richland Operations Office, the US Environmental Protection Agency, and the Washington State Department of Ecology agreed that liquid effluent discharges to the ground on the Hanford Site which affect groundwater or have the potential to affect groundwater would be subject to permitting under the structure of Chapter 173--216 (or 173--218 where applicable) of the Washington Administrative Code, the State Waste Discharge Permit Program. As a result of this decision, the Washington State Department of Ecology and the US Department of Energy, Richland Operations Office entered into Consent Order No. DE91NM-177, (Ecology and DOE-RL 1991). The Consent Order No. DE91NM-177 requires a series of permitting activities for liquid effluent discharges. Liquid effluents on the Hanford Site have been classified as Phase I, Phase II, and Miscellaneous Streams. The Consent Order No. DE91NM-177 establishes milestones for State Waste Discharge Permit application submittals for all Phase I and Phase II streams, as well as the following 11 Miscellaneous Streams as identified in Table 4 of the Consent Order No. DE91NM-177.

  6. Microprobe analysis in human pathology

    International Nuclear Information System (INIS)

    Baker, D.; Kupke, K.G.; Ingram, P.; Roggli, V.L.; Shelburne, J.D.

    1985-01-01

    This tutorial paper reviews the literature on the application of microprobe analysis to practical problems in diagnostic human pathology. The goal is to allow the reader ready access to the literature on specific clinical problems. Specimen preparation and commonly encountered artifacts are also considered. It is concluded that energy dispersive x-ray microanalysis and back-scattered electron imaging are at present the most generally useful microprobe techniques for clinical work, and are no longer solely research tools. The findings often have diagnostic, therapeutic, and/or legal implications. 332 references

    This pilot study investigated the partnership status and the level of pathological buying (PB) in 157 female patients with PB and 1153 women from a German population-based sample. Slightly more than half of both samples were currently living with a partner. The results suggest a protective effect of being in a couple relationship in the representative sample. In contrast, having a partner was not related to the severity of PB among patients. Future studies should address the question of whether the characteristics and quality of partnership have an impact on the severity and course of PB, and vice versa.

    . Salt depletion leads to a large electric field resulting in a local pH shift within the membrane with the effect that the membrane discharges and loses its ion selectivity. Since salt co-ions, H+ ions, and OH- ions contribute to OLC, CIMD interferes with electrodialysis (salt counterion removal...... neglects chemical effects and remains to be quantitatively tested. Here, we show that charge regulation and water self-ionization can lead to OLC by "current-induced membrane discharge'' (CIMD), even in the absence of fluid flow, in ion-exchange membranes much thicker than the local Debye screening length...

    Klinger, T.; Krahnstover, N. O.; Mausbach, T.; Piel, A.

    2000-01-01

    Recent experimental work on taming instabilities in plasma discharges is discussed. Instead of suppressing instabilities, it is desired to achieve control over their dynamics, done by perturbing appropriately the current flow in the external circuit of the discharge. Different discrete and continuous feedback as well as open-loop control schemes are applied. Chaotic oscillations in plasma diodes are controlled using the OGY discrete feedback scheme. This is demonstrated both in experiment and computer simulation. Weakly developed ionization wave turbulence is tamed by continuous feedback control. Open-loop control of stochastic fluctuations - stochastic resonance - is demonstrated in a thermionic plasma diode. (author)

  13. Dopamine Agonists and Pathologic Behaviors

    Directory of Open Access Journals (Sweden)

    Brendan J. Kelley

    2012-01-01

    Full Text Available The dopamine agonists ropinirole and pramipexole exhibit highly specific affinity for the cerebral dopamine D3 receptor. Use of these medications in Parkinson’s disease has been complicated by the emergence of pathologic behavioral patterns such as hypersexuality, pathologic gambling, excessive hobbying, and other circumscribed obsessive-compulsive disorders of impulse control in people having no history of such disorders. These behavioral changes typically remit following discontinuation of the medication, further demonstrating a causal relationship. Expression of the D3 receptor is particularly rich within the limbic system, where it plays an important role in modulating the physiologic and emotional experience of novelty, reward, and risk assessment. Converging neuroanatomical, physiological, and behavioral science data suggest the high D3 affinity of these medications as the basis for these behavioral changes. These observations suggest the D3 receptor as a therapeutic target for obsessive-compulsive disorder and substance abuse, and improved understanding of D3 receptor function may aid drug design of future atypical antipsychotics.

    1999-01-01

    To correlate sonographic appearance and histopathologic findings of fibroadenomas. Forty-one biopsy-proven fibroadenomas were retrospectively evaluate for sonographic-pathologic correlation. The fibroadenomas were histologically classified into sclerotic, myxoid, glandular and mixed type. The stromal cellularity and fibrosis were also classified into mild and severe. The internal echotexture and posterior acoustic enhancement of mass in ultrasonogram were correlated with histopathologic findings. The pathologic types of fibroadenomas were sclerotic in sixteen, myxoid in thirteen, and glandular or mixed in each of six cases. Most of the sclerotic type showed hypoechoic internal echotexture (68.8%) and myxoid and glandular types showed isoechoic internal echotexture (84.6%, 83.3% respectively). The hypoechoic masses showed 12 cases of mild (75.0%) and 4 cases of severe (25.0%) in cellularity and 3 cases of mild (18.7%) and 13 cases (81.3%) of sever degree in fibrosis. Most of the myxoid type (77%) showed posterior enhancement, and most of the sclerotic type (87.5%) did not show posterior enhancement on ultrasonogram. Posterior enhancement was absent in 22 cases, in which 4 cases (18.2%) showed mild and 18 cases (81.2%) showed severe degree of fibrosis. Sclerotic type with mild cellularity and severe fibrosis on histopathology showed hypoechogenicity on ultrasonogram; whereas myxoid and glandular types were predominantly isoechoic. Most of the myxoid type showed posterior enhancement. Sclerotic type with mild cellularity and severe fibrosis did not show posterior enhancement.

    Poller, D N; Glaysher, S

    2017-12-01

    This review summarises molecular pathological techniques applicable to thyroid FNA. The molecular pathology of thyroid tumours is now fairly well understood. Molecular methods may be used as a rule-in test for diagnosis of malignancy in thyroid nodules, eg BRAF V600E point mutation, use of a seven-gene mutational panel (BRAF V600E, RAS genes, RET/PTC or PAX8/PPARG rearrangement), or as a comprehensive multigene next-generation sequencing panel, eg ThyroSeq v2. Molecular methods can also be applied as rule-out tests for malignancy in thyroid nodules, eg Afirma or ThyroSeq v2 or as markers of prognosis, eg TERT promoter mutation or other gene mutations including BRAF V600E, TP53 and AKT1, and as tests for newly defined tumour entities such as non-invasive follicular thyroid neoplasm with papillary like nuclei, or as a molecular marker(s) for targeted therapies. This review describes practical examples of molecular techniques as applied to thyroid FNA in routine clinical practice and the value of molecular diagnostics in thyroid FNA. It describes the range of molecular abnormalities identified in thyroid nodules and thyroid cancers with some practical applications of molecular methods to diagnosis and prognosis of thyroid nodules and thyroid cancer. © 2017 John Wiley & Sons Ltd.

    2010-01-01

    This chapter includes discussion of the molecular pathology of tissue, blood, urine, and expressed prostatic secretions. Because we are unable to reliably image the disease in vivo, a 12 core method that oversamples the peripheral zone is widely used. This generates large numbers of cores that need to be carefully processed and sampled. In spite of the large number of tissue cores, the amount of tumor available for study is often quite limited. This is a particular challenge for research, as new biomarker assays will need to preserve tissue architecture intact for histopathology. Methods of processing and reporting pathology are discussed. With the exception of ductal variants, recognized subtypes of prostate cancer are largely confined to research applications, and most prostate cancers are acinar. Biomarker discovery in urine and expressed prostatic secretions would be useful since these are readily obtained and are proximate fluids. The well-known challenges of biomarker discovery in blood and urine are referenced and discussed. Mediators of carcinogenesis can serve as biomarkers as exemplified by mutations in PTEN and TMPRSS2:ERG fusion. The use of proteomics in biomarker discovery with an emphasis on imaging mass spectroscopy of tissues is discussed. Small RNAs are of great interest, however, their usefulness as biomarkers in clinical decision making remains the subject of ongoing research. The chapter concludes with an overview of blood biomarkers such as circulating nucleic acids and tumor cells and bound/free isoforms of prostate specific antigen (PSA).

  17. The long Tramp from Cellular Pathology to Molecular Pathology

    Derivatives: The observation of principal identity of biological meaningful elements can be agglutinated to a ‘general theory of live’ and its manifestation. All of the investigated elements posses the same regularities, which are altered, destroyed or newly built by external influences such as disease, physical and psychological forces. Not all magnification levels that display with these elements are of the same significance. Already Virchow suggested that ‘smaller elements (molecules might be responsible for changes that are visible ‘in larger elements’ (at cellular level.  The reflection on these ideas can be associated with the implementation of molecular techniques which has been developed in the 20th century and are still ongoing today. Perspectives: Thus, cellular and molecular pathology can be integrated under one umbrella. This umbrella will lead to newly man-formed structures, such as artificial DNA and gene components or functional chip implantations.

  18. Diagnostic value of ductogalactography and cytology in the proliferative changes of the mammary ducts

    International Nuclear Information System (INIS)

    Sessa, M.; Cerroni, L.; Bertolotti, A.

    1991-01-01

    Three hundred and thiyrty-six patients with nipple discharge and neither physical signs at breast examination nor pathological findings at mammography, were observed from 1984 to 1988 and studied by means of ductogalactography and cytology of discharge. Of this group, 76 patients (22%) underwent surgery and histology. In 65/76 cases proliferative pathologic conditions were demonstrated: 51 single/ multiple papillomas and 14 carcinomas. Ductogalactography suggested proliferative pathologic conditions in 59 cases and cytology of discharge showed blood in 44 patients, papillary clusters in 23, and atypical cells in 15 (both as single occurrences and in association). In cancer patients discharge appeared to be mostly spontaneous, monoductal and blood-stained. In papillomas, induced discharge was almost as frequent as spontaneous discharge, and milky discharge was also present. Ductogalactography confirmed its value in the diagnosis of proliferative pathologic conditions of the mammary ducts, being especially useful to detect carcinomas without palpable tumors. Cytology of discharge had poorer diagnostic significance

    Springer, Abraham E.; Stevens, Lawrence E.

    2009-02-01

    Although springs have been recognized as important, rare, and globally threatened ecosystems, there is as yet no consistent and comprehensive classification system or common lexicon for springs. In this paper, 12 spheres of discharge of springs are defined, sketched, displayed with photographs, and described relative to their hydrogeology of occurrence, and the microhabitats and ecosystems they support. A few of the spheres of discharge have been previously recognized and used by hydrogeologists for over 80 years, but others have only recently been defined geomorphologically. A comparison of these spheres of discharge to classification systems for wetlands, groundwater dependent ecosystems, karst hydrogeology, running waters, and other systems is provided. With a common lexicon for springs, hydrogeologists can provide more consistent guidance for springs ecosystem conservation, management, and restoration. As additional comprehensive inventories of the physical, biological, and cultural characteristics are conducted and analyzed, it will eventually be possible to associate spheres of discharge with discrete vegetation and aquatic invertebrate assemblages, and better understand the habitat requirements of rare or unique springs species. Given the elevated productivity and biodiversity of springs, and their highly threatened status, identification of geomorphic similarities among spring types is essential for conservation of these important ecosystems.

    Turnipseed, D. Phil; Sauer, Vernon B.

    2010-01-01

    The techniques and standards for making discharge measurements at streamflow gaging stations are described in this publication. The vertical axis rotating-element current meter, principally the Price current meter, has been traditionally used for most measurements of discharge; however, advancements in acoustic technology have led to important developments in the use of acoustic Doppler current profilers, acoustic Doppler velocimeters, and other emerging technologies for the measurement of discharge. These new instruments, based on acoustic Doppler theory, have the advantage of no moving parts, and in the case of the acoustic Doppler current profiler, quickly and easily provide three-dimensional stream-velocity profile data through much of the vertical water column. For much of the discussion of acoustic Doppler current profiler moving-boat methodology, the reader is referred to U.S. Geological Survey Techniques and Methods 3-A22 (Mueller and Wagner, 2009). Personal digital assistants (PDAs), electronic field notebooks, and other personal computers provide fast and efficient data-collection methods that are more error-free than traditional hand methods. The use of portable weirs and flumes, floats, volumetric tanks, indirect methods, and tracers in measuring discharge are briefly described.

    1984-01-01

    We have theoretically studied the initial chemical processing steps which occur in pulseless, negative, dc corona discharges in flowing air. A rate equation model is used because these discharges consist of a very small ionization zone near the pin with most of the pin-plane gap filled by a drift zone where both the electric field and the electron density are relatively uniform. The primary activated species are N 2 (A),O and O 2 (a 1 Δ). The predicted activated species density due to one discharge is 100 ppm per ms . mA cm 2 assuming E/n=60 Td. In pure, dry air the final product due to these activated species is primarily O 3 . The NO /sub x/ production is about 0.5 ppm per mA. In moist air there is an additional production of about 1.5 ppm per mA of HO /sub x/ species. The predicted ozone formation reactions will be ''intercepted'' when impurities are present in the air. Impurities present at densities below about 0.1% will react primarily with the activated species rather than with electrons. Hence the predicted activated species density provides an estimate of the potential chemical processing performance of the discharge

    2006-01-01

    Experimental results of discharge cleaning of carbon deposits are presented. Deposits were prepared by creating plasma in pure methane. The methane was cracked in RF discharge at the output power of 250 W. The resultant radicals were bonded to the wall of discharge vessel forming a thin film of hydrogenated black carbon with the thickness of about 200nm. The film was then cleaned in situ by oxygen plasma with the density of about 1x10 16 m -3 , electron temperature of 5 eV, neutral gas kinetic temperature of about 100 0 C and neutral atom density of 6x10 21 m -3 . The treatment time was 30 minutes. The efficiency of plasma cleaning was monitored by optical emission spectroscopy. As long as the wall was contaminated with carbon deposit, substantial emission of the CO molecules was detected. As the cleaning was in progress, the CO emission was decreasing and vanished after 30 minutes when the discharge vessel became free of any carbon. The results are explained by interaction of plasma radicals with carbon deposits. (author)

    Slot machines are among the most addictive forms of gambling, and pathological gambling slot machine players represent the largest group of treatment seekers, accounting for 35% to 93% of the population. Pathological gambling sufferers have significantly higher response frequency (games / time......) on slot machines compared with non-problem gamblers, which may suggest increased reinforcement of the gambling behavior in pathological gambling. However, to date it is unknown whether or not the increased response frequency in pathological gambling is associated with symptom severity of the disorder....... This study tested the hypothesis that response frequency is associated with symptom severity in pathological gambling. We tested response frequency among twenty-two pathological gambling sufferers and twenty-one non-problem gamblers on a commercially available slot machine, and screened for pathological...

    2003-01-01

    Till this time known methods of the excitation of the discharge between electrodes are using either secondary or thermo emission of electrons by the cathode. Usually we speak about the self-maintained discharge. Lifetime of the cathode, that is shortened by the emission, limits in principle, the lifetime of the whole discharge tube. The discharge can, according to the present state of the art, be induced also by the inductive way. Arrangement for excitation of such discharge is rather expensive. The construction of the inductive excited discharge tube is considerably influenced by the necessity of the limitation of the losses in excitation magnetic circuits. Especially length of the discharge and pressure of the working gas are limited by the economic standpoints. Function of the discharge is always connected with unwanted electromagnetic radiation, whose restraint is expensive and represents limiting factor for arrangement of the discharge tube (Authors)

  9. The Neuropsychopharmacology of Pathological Gambling.

    Science.gov (United States)

    Zakeri, Kourosh; Potenza, Marc N

    2012-02-01

    Pathological gambling (PG) is an impulse control disorder with prevalence estimates in the range of 0.2-2% in the general population. PG can significantly impact one's ability to function as it may negatively influence social, financial, and occupational aspects of life. Historically, PG has received relatively little attention from researchers and clinicians, and few treatments, particularly pharmacological, have been both validated and widely employed. Given the clinical relevance of PG, it is important that researchers examine pharmacological and behavioral treatments for their safety and efficacy and that clinicians use empirically validated therapies. Multiple neurochemicals, including serotonin, dopamine, norepinephrine, and opioids, and related neurocircuitry, particularly ventral cortico-striatal pathways, have been implicated in PG. The neurobiological rationale for therapies, particularly pharmacological ones, is reviewed with a perspective on the generation of improved prevention and treatment strategies for PG.

  10. Contemporary pharmacotherapy and iatrogenic pathology

    Directory of Open Access Journals (Sweden)

    Trailović D.R.

    2005-01-01

    Full Text Available During the past few decades, the pharmaceutical industry has developed into a powerful human activity highly influencing modern medicine. Thousands of synthetic therapeuticals have been developed, and these formulations enabled the successful treatment of many diseases, some of which were considered incurable. An increase in drug consumption followed the development of the pharmaceutical industry and the introduction of synthetic drugs. The widespread use of new medicals enabled the collection of data confirming their effectiveness, but also more and more data concerning side and unwanted effects were reported. Frequent side/unwanted effect reports gave rise to development of iatrogenic pathology, a new branch of clinical pathology. The knowledge of the possible unwanted effects of drugs on macro organisms did not enable the effective withdrawal of such formulations from the market. At the beginning, the reports concerning unwanted effects were not verealed. Consequently some potentially harmful formulations were used for years without methodical analyses of their side/unwanted effects. Some potentially dangerous formulations are still on the market such as drugs containing ulcerogenic, hepatotoxic, nephrotoxic substances as well as those inducing bone marrow aplasia. The administration of these potentially dangerous formulations is understandable in the case of clear therapeutic indications allowing no alternatives. In these cases the risk of harmful side effects is greatly overwhelmed by the risk from the primary disease. Otherwise the administration of the potentially harmful drug is unjustified, especially if the indication is not a disease. Many potentially harmful drugs are formulated for use in healthy animals, recommended as growth, laying and milk stimulators, those allowing higher speed and strength in sport and racing horses, estrus inducers and suppressors. The misuse or maluse medication is highly present in sport horses daily

    2016-09-01

    Animal sexual abuse (ASA) involves harm inflicted on animals for the purposes of human sexual gratification and includes such terms as bestiality, zoophilia, zoosadism, animal sexual assault, and others. The prevalence of ASA is not known, although it may be more common than is currently perceived. Veterinarians have the skills required to identify and document cases of ASA. This article reviews the terminology, legal definitions and forms of ASA, and its social and psychological context. An investigative approach is outlined, including an alternate light source examination; collection of swabs for DNA analysis; sampling vaginal washes, rectal washes, and toenails for trace evidence and biologic analyses; radiographic studies; and a complete forensic necropsy, including histopathology. Gross lesions identified in ASA victims include injuries to the anus, rectum, penis, scrotum, nipples, and vagina; the presence of foreign bodies; and abrasions, bruising, and other evidence of nonaccidental injury. Specialized procedures, including examination using alternate light sources and screening tests to identify human seminal fluid within samples from ASA victims, are of potential value but have not been validated for use in animals. © The Author(s) 2016.

    1979-01-01

    Experimental and theoretical studies of runaway electrons in toroidal devices are reviewed here, with particular reference to tokamaks. The complex phenomenology of runaway effects, which have been the subject of research for the past twenty years, is organized within the framework of a number of physical models. The mechanisms and rates for runaway production are discussed first, followed by sections on runaway-driven kinetic relaxation processes and runaway orbit confinement. Next, the equilibrium and stability of runaway-dominated discharges are reviewed. Models for runaway production at early times in the discharge and the scaling of runaway phenomena to larger devices are also discussed. Finally, detection techniques and possible applications of runaways are mentioned. (author)

    Full Text Available The gist of my hypothesis (.. is a certain abnormal chromatin constitution. Each process, which brings about this chromatin constitution, would result in the origin of a malignant tumour. Certainly, I consider irregularities with mitosis as the normal mode of the origin of an incorrectly assembled nucleus. This statement by Boveri (1914 has considered earlier observations of asymmetric divisions in human cancers (Hansemann, 1890. The hypothesis is based on the understanding of mitosis as an equational bipartition of the hereditary substance (Flemming, 1879; Roux, 1883. Latest since it was known that genes are located on chromosomes (Sturtevant, 1913, their balanced transport in anaphase appeared as a condition of correct somatic proliferation. True mitoses guarantee the constancy of terminally differentiated tissues. Politzer (1934 has performed X-ray experiments to investigate abnormal karyokinesis with regard to anomalous chromatin condensation, chromosome breakage, spindle malformation, and failure in cytokinesis. On the basis of light microscopy, further significant progress in understanding the pathology of mitosis was not possible. Tumour cases with reduced chromosome numbers seduced to the idea that mitotic activity is rather under cytoplasmic than under nuclear control (Koller, 1947.

  18. Internal Electrostatic Discharge Monitor - IESDM

    Science.gov (United States)

    Kim, Wousik; Goebel, Dan M.; Jun, Insoo; Garrett, Henry B.

    2011-01-01

    A document discusses an innovation designed to effectively monitor dielectric charging in spacecraft components to measure the potential for discharge in order to prevent damage from internal electrostatic discharge (IESD). High-energy electrons penetrate the structural materials and shielding of a spacecraft and then stop inside dielectrics and keep accumulating. Those deposited charges generate an electric field. If the electric field becomes higher than the breakdown threshold (approx. =2 x 10(exp 5) V/cm), discharge occurs. This monitor measures potentials as a function of dielectric depth. Differentiation of potential with respect to the depth yields electric field. Direct measurement of the depth profile of the potential in a dielectric makes real-time electronic field evaluation possible without simulations. The IESDM has been designed to emulate a multi-layer circuit board, to insert very thin metallic layers between the dielectric layers. The conductors serve as diagnostic monitoring locations to measure the deposited electron-charge and the charge dynamics. Measurement of the time-dependent potential of the metal layers provides information on the amount of charge deposited in the dielectrics and the movement of that charge with time (dynamics).

    Full Text Available The purpose of the review was analysis of literature data relating to the molecular genetic basis and diagnosis of endocrine pathology. We searched for published and unpublished researches using Pubmed as the search engine by the keywords: ‘genes’, ‘endocrine diseases’, ‘molecular diagnostics’, ‘prohormones’, ‘nuclear receptors and transcription factors’, taking into consideration studies conducted over the last 10 years, citation review of relevant primary and review articles, conference abstracts, personal files, and contact with expert informants. The criterion for the selection of articles for the study was based on their close relevance to the topic, thus out of 144 analyzed articles, the findings of the researchers covered in 32 articles were crucial. The described nosologies presented various heredi­tary forms of hypopituitarism, disturbances of steroid hormone biosynthesis, abnormal gender formation, monogenic forms of diabetes mellitus, endocrine tumors, etc. Pathology is identified that is associated with a mutation of genes encoding protein prohormones, receptors, steroid biosynthesis enzymes, intracellular signaling molecules, transport proteins, ion channels, and transcription factors. Among the endocrine diseases associated with defects in genes encoding protein prohormones, the defects of the GH1 gene are most common, the defects in the gene CYP21A2 (21-hydroxylase are among diseases associated with defects in genes encoding enzymes. More often mutations of genes encoding proteins belong to the class of G-protein coupled receptors. Most of the mutations associated with MEN-2A are concentrated in the rich cysteine region of the Ret receptor. More than 70 monogenic syndromes are known, in which there is a marked tolerance to glucose and some form of diabetes mellitus is diagnosed, diabetes mellitus caused by mutation of the mitochondrial gene (mutation tRNALeu, UUR is also detected.

    To evaluate the association between time of postpartum discharge and symptoms indicative of complications during the first postpartum week. Women with vaginal delivery at a Mexico City public hospital, without complications before the hospital discharge, were interviewed seven days after delivery. Time of postpartum discharge was classified as early (25 hours). The dependent variable was defined as the occurrence and severity of puerperal complication symptoms. Out of 303 women, 208 (68%) were discharged early. However, women with early discharge and satisfactory prenatal care had lower odds of presenting symptoms in early puerperium than women without early discharge and inadequate prenatal care (OR 0.36; 95% confidence intervals = 0.17-0.76). There was no association between early discharge and symptoms of complications during the first postpartum week; the odds of complications were lower for mothers with early discharge and satisfactory prenatal care.

    Early discharge hospital at home is a service that provides active treatment by healthcare professionals in the patient's home for a condition that otherwise would require acute hospital inpatient care. This is an update of a Cochrane review. To determine the effectiveness and cost of managing patients with early discharge hospital at home compared with inpatient hospital care. We searched the following databases to 9 January 2017: the Cochrane Effective Practice and Organisation of Care Group (EPOC) register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, and EconLit. We searched clinical trials registries. Randomised trials comparing early discharge hospital at home with acute hospital inpatient care for adults. We excluded obstetric, paediatric and mental health hospital at home schemes.   DATA COLLECTION AND ANALYSIS: We followed the standard methodological procedures expected by Cochrane and EPOC. We used the GRADE approach to assess the certainty of the body of evidence for the most important outcomes. We included 32 trials (N = 4746), six of them new for this update, mainly conducted in high-income countries. We judged most of the studies to have a low or unclear risk of bias. The intervention was delivered by hospital outreach services (17 trials), community-based services (11 trials), and was co-ordinated by a hospital-based stroke team or physician in conjunction with community-based services in four trials.Studies recruiting people recovering from strokeEarly discharge hospital at home probably makes little or no difference to mortality at three to six months (risk ratio (RR) 0.92, 95% confidence interval (CI) 0.57 to 1.48, N = 1114, 11 trials, moderate-certainty evidence) and may make little or no difference to the risk of hospital readmission (RR 1.09, 95% CI 0.71 to 1.66, N = 345, 5 trials, low-certainty evidence). Hospital at home may lower the risk of living in institutional setting at six months (RR 0.63, 96% CI

    Low birth weight serves as a crude proxy for impaired growth during fetal life and indicates a failure for the fetus to achieve its full growth potential. Low birth weight can occur in response to numerous etiologies that include complications during pregnancy, poor prenatal care, parental smoking, maternal alcohol consumption or stress. Numerous epidemiological and experimental studies demonstrate that birth weight is inversely associated with blood pressure and coronary heart disease. Sex and age impact the developmental programming of hypertension. In addition, impaired growth during fetal life also programs enhanced vulnerability to a secondary insult. Macrosomia, which occurs in response to maternal obesity, diabetes and excessive weight gain during gestation, is also associated with increased cardiovascular risk. Yet, the exact mechanisms that permanently change the structure, physiology and endocrine health of an individual across their lifespan following altered growth during fetal life are not entirely clear. Transmission of increased risk from one generation to the next in the absence of an additional prenatal insult indicates an important role for epigenetic processes. Experimental studies also indicate that the sympathetic nervous system, the renin angiotensin system, increased production of oxidative stress and increased endothelin play an important role in the developmental programming of blood pressure in later life. Thus, this review will highlight how adverse influences during fetal life and early development program an increased risk for cardiovascular disease including high blood pressure and provide an overview of the underlying mechanisms that contribute to the fetal origins of cardiovascular pathology.

Therefore it considers very important the community aspect and the social existence of the person, it must be that within an active protagonist. Each person, therefore, should feel responsible for their own condition and must be fire "exercise opinions more control over health and over their own their environments, and to make choices conducive to health." To achieve this it is essential to enable people to learn throughout life, to prepare themselves for all of its stages and to be fire cope with injuries and chronic diseases. This should be made possible at school, at home, in the workplace and in all community settings. The purpose of the “Ottawa Charter” are really ambitious if one takes into account that not all western industrialized countries, starting from the USA, put into practice social policies that can raise standards of health, requiring structural reforms of the welfare state.

    We report our experience with 43 retroperitoneal laparoscopic nephrectomy for benign kidney disease. All patients had a poor function from obstructive uropathology and renal atrophy. None of these patients had a previous lumbotomy. Retroperitoneoscopy was performed with 4 trocar port technique in a lateral position. The retroperitoneal space is created by using a Gaur's balloon made of sterile glove. The approach to vascular pedicle was done posteriorly and vessels were clipped by metal and Hem-o-lock (Weck Closure Systems, North Carolina, USA) clips. The sample was intact extracted in an Endo-Bag prolonging one trocar incision. Median operative time was 160 minutes and median blood loss was 200 mL. Four cases (9%) were converted to open surgery: one case due to bleeding and 3 cases due to technical difficulties regarding perirenal adherences. Most patients (39) checked out from the Hospital in day two. Four of them were left over 3 days due to wound complications. Retroperitoneoscopy offers a safe, effective and reproductive access to nephrectomy for benign pathologies.

    Pathological gambling (PG) affects about 0.2-2% of adults and the impact extends to family members, employers and society as a whole. Recent research has identified similarities in the pathophysiologies of PG and substance use disorders (SUDs). As such, findings regarding SUDs provide a framework for investigating PG. The aims of the manuscript are two-fold. First, we will briefly revivew neural systems implicated in PG. Cortico-limbic circuitry involving the ventral striatum, ventromedial prefrontal cortex, anterior cingulate cortex, and dorsolateral prefrontal cortex are discussed as are the neurotransmitters norepinephrine, serotonin, dopamine, opioids, glutamate, and gamma-aminobutyric acid (GABA). This background will provide a framework for reviewing the psychopharmacological treatments that have been tested for efficacy and safety in treating PG. Of medications, the strongest data suggest the efficacy and tolerability of opioid antagonists in the treatment of PG, and other agents have varying degree of empirical support. As behavioral therapies have also shown efficacy, they will be briefly considered as well. Future research is needed to understand how treatments work in PG and for whom specific treatments might work best.

    When the background pressure and the discharge current in a gas discharge are raised the plasma column is tightened up into a filament. Then the discharge occupies a region of the discharge tube whose transverse dimensions are substantially less than those of the tube. This contraction phenomenon in discharges restricts the range of parameters used in various devices to the range of relatively low discharge currents and low gas pressures. This contraction interferes with creating high-power gas lasers, since it acts destructively on the lasing process. In order to suppress filamentation of discharges the working gas has been pumped through the system at high speed, with considerable success. The turbulent mixing in the stream plays an important role in creating an uncontracted discharge at high pressures. The purpose of the present work is to study the possibility of undoing the contraction of a nitrogen discharge, which is one of the main components in the operation of a CO 2 laser, by introducing an intense sound wave in the discharge tube. Discharge contraction and the effect of a sound wave propagating along the plasma column have been investigated experimentally in nitrogen by studying the current-voltage characteristics of a contracted discharge. 6 refs., 3 figs

    Increase in internet use and video-gaming contributes to public concern on pathological or obsessive play of video games among children and adolescents worldwide. Nevertheless, little is known about the prevalence of pathological symptoms in video-gaming among Singaporean youth and the psychometric properties of instruments measuring pathological symptoms in video-gaming. A total of 2998 children and adolescents from 6 primary and 6 secondary schools in Singapore responded to a comprehensive survey questionnaire on sociodemographic characteristics, video-gaming habits, school performance, somatic symptoms, various psychological traits, social functioning and pathological symptoms of video-gaming. After weighting, the survey data were analysed to determine the prevalence of pathological video-gaming among Singaporean youth and gender differences in the prevalence. The construct validity of instrument used to measure pathological symptoms of video-gaming was tested. Of all the study participants, 8.7% were classified as pathological players with more boys reporting more pathological symptoms than girls. All variables, including impulse control problem, social competence, hostility, academic performance, and damages to social functioning, tested for construct validity, were significantly associated with pathological status, providing good evidence for the construct validity of the instrument used. The prevalence rate of pathological video-gaming among Singaporean youth is comparable with that from other countries studied thus far, and gender differences are also consistent with the findings of prior research. The positive evidence of construct validity supports the potential use of the instrument for future research and clinical screening on Singapore children and adolescents' pathological video-gaming.

To describe a subset of speech-language pathology (SLP) patients in the Post-Stroke Rehabilitation Outcomes Project and to examine outcomes for patients with low admission FIM levels of auditory comprehension and verbal expression. Observational cohort study. Five inpatient rehabilitation hospitals. Patients (N=397) receiving post-stroke SLP with admission FIM cognitive components at levels 1 through 5. Not applicable. Increase in comprehension and expression FIM scores from admission to discharge. Cognitively and linguistically complex SLP activities (problem-solving and executive functioning skills) were associated with greater likelihood of success in low- to mid-level functioning communicators in the acute post-stroke rehabilitation period. The results challenge common clinical practice by suggesting that use of high-level cognitively and linguistically complex SLP activities early in a patient's stay may result in more efficient practice and better outcomes regardless of the patient's functional communication severity level on admission.

    To apply social network analysis (SNA) to investigate whether frequency and severity of gambling problems were associated with different network characteristics among friends, family and co-workers is an innovative way to look at relationships among individuals; the current study was the first, to our knowledge, to apply SNA to gambling behaviors. Egocentric social network analysis was used to characterize formally the relationships between social network characteristics and gambling pathology. Laboratory-based questionnaire and interview administration. Forty frequent gamblers (22 non-pathological gamblers, 18 pathological gamblers) were recruited from the community. The SNA revealed significant social network compositional differences between the two groups: pathological gamblers (PGs) had more gamblers, smokers and drinkers in their social networks than did non-pathological gamblers (NPGs). PGs had more individuals in their network with whom they personally gambled, smoked and drank than those with who were NPG. Network ties were closer to individuals in their networks who gambled, smoked and drank more frequently. Associations between gambling severity and structural network characteristics were not significant. Pathological gambling is associated with compositional but not structural differences in social networks. Pathological gamblers differ from non-pathological gamblers in the number of gamblers, smokers and drinkers in their social networks. Homophily within the networks also indicates that gamblers tend to be closer with other gamblers. This homophily may serve to reinforce addictive behaviors, and may suggest avenues for future study or intervention. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Academic Pathology is a key player in human molecular science and in the powerful initiatives of the National Institutes of Health. Pathologists generate data crucial to virtually every molecular study of human tissue, and have the necessary skills and authority to oversee processing of human tissues for research analysis. We advocate that Academic Pathology is optimally positioned to drive the molecular revolution in study of human disease, through human tissue collection, analysis, and databasing. This can be achieved through playing a major role in human tissue procurement and management; establishing high-quality 'Pathology Resource Laboratories'; providing the scientific expertise for pathology data sharing; and recruiting and training physician scientists. Pathology should position itself to be the local institutional driver of technology implementation and development, by operating the resource laboratories, providing the expertise for technical and conceptual design of research projects, maintaining the databases that link molecular and morphological information on human tissues with the requisite clinical databases, providing education and mentorship of technology users, and nurturing new research through the development of preliminary data. We also consider that outstanding pathology journals are available for the publication of research emanating from such studies, to the benefit of the pathology profession as an academic enterprise. It is our earnest hope that Academic Pathology can play a leading role in the remarkable advances to be made as the 21st century unfolds.

    Endocrine pathology is the subspecialty of diagnostic pathology which deals with the diagnosis and characterisation of neoplastic and non-neoplastic diseases of the endocrine system. This relatively young subspecialty was initially focused mainly on thyroid and parathyroid pathology, with some participants also involved in studies of the pituitary, the endocrine pancreas, and the adrenal glands. However, the endocrine system involves much more than these traditional endocrine organs and the discipline has grown to encompass lesions of the dispersed neuroendocrine cells, including neuroendocrine tumours (NETs) of the lungs, gastrointestinal tract, thymus, breast and prostate, as well as paraganglia throughout the body, not just in the adrenals. Indeed, the production of hormones is the hallmark of the endocrine system, and some aspects of gynecological/testicular, bone and liver pathology also fall into the realm of this specialty. Many of the lesions that are the focus of this discipline are increasing in incidence and their pathology is becoming more complex with increased understanding of molecular pathology and a high incidence of familial disease. The future of endocrine pathology will demand a depth of understanding of structure, function, prognosis and prediction as pathologists play a key role in the multidisciplinary care team of patients with endocrine diseases. It is anticipated that new technologies will allow increased subspecialisation in pathology and growth of this important area of expertise.

    Narrow gap electronegative (EN) capacitive discharges are widely used in industry and have unique features not found in conventional discharges. In this paper, plasma parameters are determined over a range of decreasing gap length L from values for which an electropositive (EP) edge exists (2-region case) to smaller L-values for which the EN region connects directly to the sheath (1-region case). Parametric studies are performed at applied voltage V{sub rf}=500 V for pressures of 10, 25, 50, and 100 mTorr, and additionally at 50 mTorr for 1000 and 2000 V. Numerical results are given for a parallel plate oxygen discharge using a planar 1D3v (1 spatial dimension, 3 velocity components) particle-in-cell (PIC) code. New interesting phenomena are found for the case in which an EP edge does not exist. This 1-region case has not previously been investigated in detail, either numerically or analytically. In particular, attachment in the sheaths is important, and the central electron density n{sub e0} is depressed below the density n{sub esh} at the sheath edge. The sheath oscillations also extend into the EN core, creating an edge region lying within the sheath and not characterized by the standard diffusion in an EN plasma. An analytical model is developed using minimal inputs from the PIC results, and compared to the PIC results for a base case at V{sub rf}=500 V and 50 mTorr, showing good agreement. Selected comparisons are made at the other voltages and pressures. A self-consistent model is also developed and compared to the PIC results, giving reasonable agreement.

  17. Double discharges in unipolar-pulsed dielectric barrier discharge xenon excimer lamps

    2003-01-01

    Excitation of dielectric barrier discharge xenon excimer lamps by unipolar short square pulses is studied in this paper. Two discharges with different polarity are excited by each voltage pulse (double discharge phenomenon). The primary discharge occurs at the top or at the rising flank of the applied unipolar square pulse, which is directly energized by the external circuit. The secondary discharge with the reversed polarity occurs at the falling flank or shortly after the falling flank end (zero external voltage) depending on the pulse width, which is energized by the energy stored by memory charges deposited by the primary discharge. Fast-speed ICCD imaging shows the primary discharge has a conic discharge appearance with a channel broadening on the anode side. This channel broadening increases with increasing the pulse top level. Only the anode-side surface discharge is observed in the primary discharge. The surface discharge on the cathode side which is present in bipolar sine voltage excitation is not observed. On the contrary, the secondary discharge has only the cathode-side surface discharge. The surface discharge on the anode side is not observed. The secondary discharge is much more diffuse than the primary discharge. Time-resolved emission measurement of double discharges show the secondary discharge emits more VUV xenon excimer radiation but less infrared (IR) xenon atomic emission than the primary discharge. It was found that the IR xenon atomic emission from the secondary discharge can be reduced by shortening the pulse width. The energy efficiency of unipolar-pulsed xenon excimer lamps (the overall energy efficiency of double discharges) is much higher than that obtained under bipolar sine wave excitation. The output VUV spectrum under unipolar pulse excitation is found to be identical to that under sine wave excitation and independent of injected electric power

    The program goal is to provide basic data for evaluating the hazard to man from radioactive materials deposited within the body. The original objective, to obtain dose-response information and to provide data from several species for extrapolating animal data to man, is receiving less attention at present as effort is being put into determining how radiation causes bone cancer and whether viruses play a role. The program began with the very early radiotoxicologic investigations of materials important in the development of the atomic bomb and the necessity to establish maximum permissible levels of exposure to these materials. With the demonstration that bone cancer is the most sensitive indicator of damage from transuranic elements and some of the fission products, bone pathology became the focus of attention. When it became evident that questions of human hazard cannot be answered unequivocally on the basis of dose-response relationships, different approaches were considered, and one based on knowledge of mechanisms of cancer induction seemed most likely to be successful. The detection of viruses in both radiation-induced and spontaneous bone cancer of mice, and the present evidence for a similar virus in bone cancer of man, support the hypothesis that radiation causes cancer by activating endogenous neoplastic information, which can also be expressed as oncornavirus. Present emphases therefore concern understanding the biological, biochemical, and physical attributes of the five murine oncornaviruses that have now been isolated in the course of the program; demonstrating the existence of a comparable human oncornavirus; and discovering how radiation and virus interact in the induction of bone cancer

    The historical events in the evolution of Alzheimer's disease are reviewed, including the initial description by Alois Alzheimer and the subsequent controversy regarding the nosological specificity of this entity. The similarity of senile dementia and Alzheimer's disease is emphasized. The basis for the modern concept of Alzheimer's disease as premature or accelerated aging is included in the review. The pathological correlates of the major categories of adult dementia have been described. The traditional criteria of neurofibrillary tangles and senile plaques have been re-evaluated using the current insight into these changes afforded by electron microscopy and biochemistry. The significance of amyloid has been described because it occurs within the senile plaque and also as the essential component of congophilic angiopathy. The new information regarding neuronal cell counts and the loss of choline acetyltransferase has been evaluated in terms of an indication of a pathogenic mechanism of Alzheimer's disease. The current understanding of normal pressure hydrocephalus, Creutzfeldt-Jakob disease, and multi-infarct dementia has been described. Brain biopsy in dementia has been described as having diagnostic, research, pathogenic, and prognostic value. The precautions involving the performance and handling of the biopsy have been stressed, particularly because these procedures involve conditions of possible slow virus etiology. The polemic for Alzheimer's disease as aging or slow virus infection has been summarized. At this time a consideration seems justified that Alzheimer's disease is an age-related, slow virus disease due to a hitherto unknown immune defect. Aging as an etiological agent must be clarified before Alzheimer's disease, in any form, can be considered to be an inevitable consequence of longevity.

    Although visual observations suggested that fish remained in the discharge for considerable periods, temperature-sensitive tags indicated the majority of fish spend less than 50 hr or 10 percent of the time at discharge temperatures. During 1974 a second fish tagging study was conducted, using temperature-sensitive tags to yield discharge residence times of Lake Michigan salmonids at Point Beach thermal discharge. Preliminary results revealed that many fish tag values were close to Unit I line indicating that calculated maximum discharge residence times for these fish will be nearly 100 percent of the elapsed time

(2) Evidence indicates that the breast is also occasionally colonized by Hp. (3) Hp may be injected retrograde up into ducts of the breast during oral nipple stimulation during sexual activity and this Hp may give rise to some cases of fibrocystic breast change.

    Among White smokers, many females use smoking as a weight control strategy. Little is known about the relationship between eating pathology and smoking among Black females, and whether smokers who enroll in treatment differ in eating pathology from smokers who decline treatment. We examined eating pathology among Black and White smokers who enrolled in a smoking cessation treatment and those who declined treatment. Participants were 100 Black and 100 White female smokers (ages 18-65) who completed three measures of eating pathology. After controlling for BMI, Whites reported greater levels of overall eating pathology than Blacks [F(1,195)=4.1; pWhite than Black smokers. However, once females seek smoking cessation treatment, these ethnic differences are not apparent.

    The trends in modern undergraduate medical education focus on a patient-centred approach through problem-based learning over the traditional modular curriculum. Integrating pathology into this style of learning has resulted in the dilution of core scientific principles which may have contributed to reduced understanding and interest in the subject. We aim to innovate pathology education by utilising National Pathology Week which is organised by the Royal College of Pathologists to develop the public engagement model which empowers students to learn pathology by teaching the public. Through this model, we hope to generate a greater interest in pathology at both undergraduate and postgraduate stages of education. We obtained funding from the Royal College of Pathologists to organise National Pathology Week at Exeter Medical School and the Royal Devon & Exeter Hospital. We involved 125 undergraduate student volunteers from health-related courses. We designed a curriculum aiming to educate both students and public on current topics such as cancer screening programmes, antibiotic resistance, diagnosis of inflammatory bowel disease and the role of pathologists. We hosted 15 pathologists, biomedical scientists and microbiologists to engage with students, share experiences and offer an insight into their careers. Through this project, we interacted with over 500 members of the public and 150 school students. The medical student volunteers developed a range of skills including competent use of microscopes to visualise pathology slides, effective communication with lay audiences to teach pathology and understanding of the clinical application of pathology. We believe the public engagement model of teaching undergraduate students has the potential to develop a greater interest in pathology whilst benefitting the wider community.

    Clinical and experimental studies on focal cortical dysplasia (FCD) were carried out. For the experimental study, an experimental FCD model of rats was developed. Twenty Wistar rats at 0-2 days after birth were used for the study. Kainic acid (KA) solution was injected stereotaxically into medial and lateral sites of the sensori-motor cortex. Bipolar electrodes were inserted. The behavior of the rats and electroencephalography (EEG) were recorded using a digital video-EEG monitoring system. After observation periods of 1, 2 and 6 months, the rats were perfused for pathological study. FCD was observed adjacent to the site of KA injection in all rats more than one month after the injection. EEG recording demonstrated focal spike discharges in and around the site of injection. However, clinical seizure was not observed. Pathological studies showed decrease in gamma aminobutyric acid (GABA)-A receptors and increase in GABA-B receptors not only in the lesion but also in perilesional areas. Fifteen surgical cases of FCD with intractable epilepsy were included in the clinical study. Neuro-imaging studies including high-resolution MRI and single photon emission computed tomography (SPECT) were performed. Conventional EEG studies demonstrated focal EEG abnormalities with epileptic phenomena. At surgery, intraoperative electrocorticography (ECoG) was performed in order to localize epileptic foci under neuroleptanalgesia. Fourteen patients showed epileptiform discharges on preresection ECoG. All foci in non-eloquent areas were resected. Pathological studies including immunohistochemical staining were performed, and characteristics of the FCD in relation to EEG findings were analyzed. Electrophysiological examination revealed epileptogenecity not only in the lesions but also in perilesional areas. In the lesions, immunohistochemical studies showed decrease in GABA-A receptors and increase in GABA-B receptors in both the lesions and perilesional areas, but N

    Full Text Available O objetivo deste estudo foi avaliar a influência de dois tipos de bebedouros nipple e taça, utilizados na dessedentação de aves de postura e o incremento da demanda de cloro na água oferecida pelos dois tipos de bebedouros estudados. Foram realizadas as contagens de coliformes totais, coliformes fecais, Escherichia coli, estreptococos fecais e microrganismos mesófilos. Os resultados obtidos figuraram que as amostras de água dos reservatórios, de ambos os bebedouros, apresentaram-se contaminadas microbiologicamente antes de passarem pelos bebedouros. A contaminação por bactérias de poluição fecal foi maior nas amostras colhidas nos bebedouros tipo taça, assim como eles foram responsáveis por um maior acúmulo de matéria orgânica, tendo então uma elevada demanda de cloro e uma maior influência na depreciação da qualidade da água fornecida às aves. Dos dois tipos de bebedouros estudados, o tipo nipple mostrou ser o menos deletério no que concerne à qualidade da água entretanto, independente do tipo de bebedouro utilizado na dessedentação das aves, a desinfecção da água é um ato imprescindível à manutenção de sua qualidade e à eliminação de futuros patógenos.

    Almost 50% of women who have had rectal surgery subsequently develop vaginal discharge. Due to the recurrent and unexpected nature of this heavy discharge, they often experience it as very distressing. Many of these women undergo extensive diagnostic tests that are mainly focused on identifying fistula formation. If no fistula is found, in most cases no other cause for severe vaginal discharge can be demonstrated. In our practice, we saw three patients (49-, 54- and 74-years-old, respectively) with similar severe vaginal discharge after rectal surgery and in whom no explanation for the vaginal discharge could be found. For this reason we conducted a literature search into this condition. Anatomical changes appear to be responsible for heavy vaginal discharge following rectal surgery. Changes in pelvic floor muscles and compression of the distal part of the vagina may lead to pooling of fluid in the proximal part of the vagina, resulting in severe discharge. Symptomatic treatment may reduce the symptoms.

    Exploiting a nonlinear resistor network on a square lattice in two dimensions, we investigate discharge when two opposite sides of the lattice are subjected to a constant voltage difference. Each site is ionized randomly with a probability in proportion to the square of the strength of the electric field, and the resistivity between two ionized sites is assumed to be 10-6 times smaller than the original resistivity. Using Monte Carlo simulation, we obtain the current and distribution of clusters of ionized sites as functions of the fraction of ionized sites. It is found that a wall of potential drop is formed as the fraction approaches a critical value, which is followed by discharge. The critical value is much smaller than the critical percolation probability of the standard site percolation on the square lattice. We also find that a singular behavior of the cluster distribution is expected at a critical fraction differently from that for the current, and that the critical exponents characterizing the cluster distribution satisfy the scaling relation known for two-dimensional percolation, while the critical exponent of the percolation probability is close to the value reported for a directed percolation.

  9. Electrostatic discharge concepts and definitions

    Many objects -like a human body, plastic wrap, or a rolling cart -that are electrically neutral, overall, can gain a net electrostatic charge by means of one of three methods: induction, physical transfer, or triboelectric charging (separation of conductive surfaces). The result is a voltage difference between the charged object and other objects, creating a situation where current flow is likely if two objects come into contact or close proximity. This current flow is known as electrostatic discharge, or ESD. The energy and voltage of the discharge can be influenced by factors such as the temperature and humidity in the room, the types of materials or flooring involved, or the clothing and footwear a person uses. Given the possible ranges of the current and voltage characteristic of an ESD pulse, it is important to consider the safety risks associated with detonator handling, assembly and disassembly, transportation and maintenance. For main charge detonators, these safety risks include high explosive violent reactions (HEVR) as well as inadvertent nuclear detonations (lND).

    Full Text Available Digital pathology is an interdisciplinary field where competency in pathology, laboratory techniques, informatics, computer science, information systems, engineering, and even biology converge. This implies that teaching students about digital pathology requires coverage, expertise, and hands-on experience in all these disciplines. With this in mind, a syllabus was developed for a digital pathology summer school aimed at professionals in the aforementioned fields, as well as trainees and doctoral students. The aim of this communication is to share the context, rationale, and syllabus for this school of digital pathology.

    Pathological jealousy evokes emotions, thoughts, and behaviors that cause damage to social and interpersonal relationships. On the other hand, pathological love is the uncontrollable behavior of caring for a partner that results in neglecting the needs of the self. The aim of the present research was to assess the similarities and differences between the two psychopathologies of love. To this end, thirty-two individuals with pathological jealousy and 33 individuals with pathological love were compared on demographics, aspects of romantic relationship (jealousy, satisfaction, love style), psychiatric co-morbidities, personality and psychological characteristics (e.g., impulsivity). In a univariate analysis individuals with pathological jealousy were more likely to be in a current relationship and reported greater satisfaction. The avoidant attachment and the ludus love style were associated with pathological jealousy whereas the secure attachment and agape love style was associated with pathological love. Almost three-quarters (72.3%) of the sample met criteria for a current psychiatric disorder, however no differences emerged between the pathological jealousy and pathological love groups. In a binary logistic regression, relationship status and impairments in parenting significantly differentiated the groups. While both pathological jealousy and pathological love share similarities, they also present with unique differences, which may have important treatment implications. Copyright © 2017 Elsevier B.V.

    There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal.

    Full Text Available Pathological gaming is an emerging and poorly understood problem. Impulsivity is commonly impaired in disorders of behavioural and substance addiction, hence we sought to systematically investigate the different subtypes of decisional and motor impulsivity in a well-defined pathological gaming cohort.Fifty-two pathological gaming subjects and age-, gender- and IQ-matched healthy volunteers were tested on decisional impulsivity (Information Sampling Task testing reflection impulsivity and delay discounting questionnaire testing impulsive choice, and motor impulsivity (Stop Signal Task testing motor response inhibition, and the premature responding task. We used stringent diagnostic criteria highlighting functional impairment.In the Information Sampling Task, pathological gaming participants sampled less evidence prior to making a decision and scored fewer points compared with healthy volunteers. Gaming severity was also negatively correlated with evidence gathered and positively correlated with sampling error and points acquired. In the delay discounting task, pathological gamers made more impulsive choices, preferring smaller immediate over larger delayed rewards. Pathological gamers made more premature responses related to comorbid nicotine use. Greater number of hours played also correlated with a Motivational Index. Greater frequency of role playing games was associated with impaired motor response inhibition and strategy games with faster Go reaction time.We show that pathological gaming is associated with impaired decisional impulsivity with negative consequences in task performance. Decisional impulsivity may be a potential target in therapeutic management.

    Aims To apply social network analysis (SNA) to investigate whether frequency and severity of gambling problems were associated with different network characteristics among friends, family, and co-workers. is an innovative way to look at relationships among individuals; the current study was the first to our knowledge to apply SNA to gambling behaviors. Design Egocentric social network analysis was used to formally characterize the relationships between social network characteristics and gambling pathology. Setting Laboratory-based questionnaire and interview administration. Participants Forty frequent gamblers (22 non-pathological gamblers, 18 pathological gamblers) were recruited from the community. Findings The SNA revealed significant social network compositional differences between the two groups: pathological gamblers (PGs) had more gamblers, smokers, and drinkers in their social networks than did nonpathological gamblers (NPGs). PGs had more individuals in their network with whom they personally gambled, smoked, and drank with than those with who were NPG. Network ties were closer to individuals in their networks who gambled, smoked, and drank more frequently. Associations between gambling severity and structural network characteristics were not significant. Conclusions Pathological gambling is associated with compositional but not structural differences in social networks. Pathological gamblers differ from non-pathological gamblers in the number of gamblers, smokers, and drinkers in their social networks. Homophily within the networks also indicates that gamblers tend to be closer with other gamblers. This homophily may serve to reinforce addictive behaviors, and may suggest avenues for future study or intervention. PMID:23072641

  15. Evolution of the Pathology Residency Curriculum

    Full Text Available The required medical knowledge and skill set for the pathologist of 2020 are different than in 2005. Pathology residency training curriculum must accordingly change to fulfill the needs of these ever-changing requirements. In order to make rational curricular adjustments, it is important for us to know the current trajectory of resident training in pathology—where we have been, what our actual current training curriculum is now—to understand how that might change in anticipation of meeting the needs of a changing patient and provider population and to fit within the evolving future biomedical and socioeconomic health-care setting. In 2013, there were 143 Accreditation Council for Graduate Medical Education-accredited pathology residency training programs in the United States, with approximately 2400 residents. There is diversity among residency training programs not only with respect to the number of residents but also in training venue(s. To characterize this diversity among pathology residency training programs, a curriculum survey was conducted of pathology residency program directors in 2013 and compared with a similar survey taken almost 9 years previously in 2005 to identify trends in pathology residency curriculum. Clinical pathology has not changed significantly in the number of rotations over 9 years; however, anatomic pathology has changed dramatically, with an increase in the number of surgical pathology rotations coupled with a decline in stand-alone autopsy rotations. With ever-expanding medical knowledge that the graduating pathology resident must know, it is necessary to (1 reflect upon what are the critical need subjects, (2 identify areas that have become of lesser importance, and then (3 prioritize training accordingly.

    2016-03-01

    Bar coding and specimen tracking are intricately linked to pathology workflow and efficiency. In the pathology laboratory, bar coding facilitates many laboratory practices, including specimen tracking, automation, and quality management. Data obtained from bar coding can be used to identify, locate, standardize, and audit specimens to achieve maximal laboratory efficiency and patient safety. Variables that need to be considered when implementing and maintaining a bar coding and tracking system include assets to be labeled, bar code symbologies, hardware, software, workflow, and laboratory and information technology infrastructure as well as interoperability with the laboratory information system. This article addresses these issues, primarily focusing on surgical pathology. Copyright © 2016 Elsevier Inc. All rights reserved.

    Kealy, David; Ogrodniczuk, John S

    2014-03-01

    Pathological narcissism is a form of maladaptive self-regulation that impedes the capacity to love. Although narcissism is often construed as excessive self-love, individuals with pathological narcissism are impaired in being able to love themselves as well as others. With the subject of impaired love in mind, we review selected conceptualizations from an enormous and diverse psychodynamic literature on narcissism. Major theoretical approaches illustrate a number of psychodynamics associated with narcissistic self-regulatory problems. This paper provides a concise overview of major conceptual themes regarding pathological narcissism and impaired capacity to love.

    2016-09-01

    The relative contribution of interictal epileptiform discharges (IEDs) to cognitive dysfunction in comparison with the underlying brain pathology is not yet understood in children with lesional focal epilepsy. The current study investigated the association of IEDs with intellectual functioning in 103 children with medication-resistant focal epilepsy. Hierarchical multiple regression analyses were used to determine the independent contribution of IED features on intellectual functioning, after controlling for effects of lesional pathology, epilepsy duration, and medication. Exploratory analyses were conducted for language and memory scores as well as academic skills available in a subset of participants. The results reveal that IEDs have a negative association with IQ with independent, additive effects documented for frequent and bilaterally distributed IEDs as well as discharge enhancement in sleep. Left-lateralized IEDs had a prominent effect on verbal intelligence, in excess of the influence of left-sided brain pathology. These effects extended to other cognitive functions, most prominently for sleep-enhanced IEDs to be associated with deficits in expressive and receptive language, reading, spelling and numerical skills. Overall, IED effects on cognition were of a magnitude similar to lesional influences or drug effects (topiramate use). This study demonstrates an association between IEDs and cognitive dysfunction, independent of the underlying focal brain pathology.

    2014-01-01

    The problem of the propagation of an electrical discharge between a spherical electrode and a plane has been solved by means of finite element methods (FEM) using a fluid approximation and assuming weak ionization and local equilibrium with the electric field. The numerical simulation of this type of problems presents the usual difficulties of convection-diffusion-reaction problems, in addition to those associated with the nonlinearities of the charged species velocities, the formation of steep gradients of the electric field and particle densities, and the coexistence of very different temporal scales. The effect of using different temporal discretizations for the numerical integration of the corresponding system of partial differential equations will be here investigated. In particular, the so-called θ-methods will be used, which allows to implement implicit, semi-explicit and fully explicit schemes in a simple way

    Stoughton, L.D.; Robinson, S.T.

    1962-05-15

    A gravity-red dispenser or valve is designed for discharging the fueled spherical elements used in a pebble bed reactor. The dispenser consists of an axially movable tube terminating under a hood having side walls with openings. When the tube is moved so that its top edge is above the tops of the side openings the elements will not flow. As the tube is moved downwardly, the elements flow into the hood through the side openings and over the top edge into the tube at an increasing rate as the tube is lowered further. The tube is spaced at all times from the hood and side walls a distance greater than the diameter of the largest element to prevent damaging of the elements when the dispenser is closed to flow.

  3. Automatic Regulation of Wastewater Discharge

    Full Text Available Wastewater plants, mainly with secondary treatments, discharge polluted water to environment that cannot be used in any human activity. When those dumps are in the sea it is expected that most of the biological pollutants die or almost disappear before water reaches human range. This natural withdrawal of bacteria, viruses and other pathogens is due to some conditions such as the salt water of the sea and the sun effect, and the dumps areas are calculated taking into account these conditions. However, under certain meteorological phenomena water arrives to the coast without the full disappearance of pollutant elements. In Mediterranean Sea there are some periods of adverse climatic conditions that pollute the coast near the wastewater dumping. In this paper, authors present an automatic control that prevents such pollution episodes using two mathematical models, one for the pollutant transportation and the other for the pollutant removal in wastewater spills.

    Lake Michigan salmon and trout were tagged with a thermoluminescent dosimeter (TLD) temperature tag to estimate their thermal exposure and residence time at a warm water discharge. Fish were collected, tagged, and released at the Point Beach Nuclear Plant, Two Rivers, Wisconsin, in the fall of 1973 and 1974. Tags were recovered during the same season, primarily from fish recaptured at Point Beach. Average uniform temperature exposure and maximum possible discharge residence time were determined. Appropriate hourly intake and discharge temperatures were averaged to calculate mean temperature exposure for the case of maximum discharge residence. Lowest discharge temperature not included within the period of maximum residence was identified to serve as a possible indicator of avoidance temperature. Mean values for the above parameters were calculated for fish species for each tagging year and are reported with the accompanying range of intake and discharge temperatures

    In the case of partial discharge training for recruits who lack of on-site work experience, the risk of physical shock and damage of the test equipment may be due to the limited skill level and improper operation by new recruits. Partial discharge simulation tester is the use of simulation technology to achieve partial discharge test process simulation, relatively true reproduction of the local discharge process and results, so that the operator in the classroom will be able to get familiar with and understand the use of the test process and equipment.The teacher sets up the instrument to display different partial discharge waveforms so that the trainees can analyze the test results of different partial discharge types.

  6. Latin American forensic pathology: scope and needs

    2012-10-01

    Full Text Available Pathology pertains to the study of a disease; from ancient times it has sought to explain the cause of death through postmortem examination. The advancement of science and technology has led to a greater definition of roles and has favored its development through different subspecialties among which we stands out forensic pathology. This discipline has its own characteristics, scope, case series, procedures and terminology. Likewise, although forensic pathology does not differ substantially from clinical pathology, significant differences can be found between the Anglo American approach and the Latin American approach. Beyond semantics of these alleged differences, the article reviews the concepts involved and discusses the scope and requirements needed to qualify experts, in the understanding that globalizing criteria should establish new paradigms and define the specific roles of the specialty.

    2005-05-01

    Several types of psychotherapy are currently used to treat pathological gamblers. These include Gambler's Anonymous, cognitive behavioral therapy, behavioral therapy, psychodynamic therapy, and family therapy. Research into which types of psychotherapy are the most effective for pathological gambling is limited but is a growing area of study. Group therapy, namely Gambler's Anonymous, provides peer support and structure. Cognitive behavior therapy aims to identify and correct cognitive distortions about gambling. Psychodynamic psychotherapy can help recovering gamblers address core conflicts and hidden psychological meanings of gambling. Family therapy is helpful by providing support and education and eliminating enabling behaviors. To date, no single type of psychotherapy has emerged as the most effective form of treatment. As in other addictive disorders, treatment retention of pathological gamblers is highly variable. Understanding the types of psychotherapy that are available for pathological gamblers, as well their underlying principles, will assist clinicians in managing this complex behavioral disorder.

  9. PLANT PATHOLOGY: a discipline at a crossroads.

    Weinhold, A R

    1996-01-01

    The Department of Plant Pathology at the University of California at Berkeley was destroyed as a consequence of a contentious reorganization. The circumstances that led to the reorganization provide some insight into the challenges facing the discipline of plant pathology. The underlying basis for plant pathology as a science is to address problems of plant disease. This requires a balance between disciplinary and problem-solving research and a continuum from achieving fundamental advances in knowledge to the development and implementation of problem-solving approaches. Changes in colleges and universities have placed extreme stress on this essential structure. The dilemma that must be addressed is how to reestablish the problem-solving continuum where it has been broken and strengthen it where it has been weakened. Plants are essential for life, and they will always be affected by disease. The understanding and management of these diseases is the responsibility and the challenge of plant pathology today and in the future.

    Alongside histomorphology and immunohistochemistry, molecular pathology is now established as one of the cornerstones in the tissue diagnosis of bone tumours. We describe the principal molecular pathological techniques employed, and each of the bone tumour entities where their identified characteristic molecular pathological changes can be detected to support and confirm the suspected histological diagnosis. Tumours discussed include fibrous dysplasia, classical and subtype osteosarcomas, central and surface cartilaginous tumours, Ewing's sarcoma, vascular tumours, aneurysmal bone cyst, chordoma, myoepithelioma, and angiomatoid fibrous histiocytoma. This is a rapidly evolving field with discoveries occurring every few months, and some of the newer entities (the Ewing's-like sarcomas), which are principally identified by their molecular pathology characteristics, are discussed. © 2013 John Wiley & Sons Ltd.

    2008-01-01

    Pathological hobbies have been studied in 82 inpatients with schizophrenia, 48 men and 34 women, aged 18-65 years. Inclusion criteria of pathology were (1) overvalued character of a hobby, (2) insufficient criticism towards this hobby, (3) fringe, singularity interests and methods of their realization; (4) inconsistency between the hobby and previous life experience, (5) low efficiency, (6) strong linkage with other psychopathological presentations, (7) chronological coincidence between the onset of pathological hobbies and schizophrenia manifestation or exacerbation, (8) susceptibility to progressive dynamics, (9) distinct social-maladaptive influence. Regarding the content, pathological hobbies are presented by creative art, scientific work, collecting, gambling, sport and health activities, "spiritual" development. Three clinical variants - obsessive-compulsive, overvalued and paranoic can be singled out by clinical presentations. The overvalued variant appears to be more favorable due to the predominantly adaptive social influence and weak relation to the dynamics of schizophrenia. Other variants are less productive exerting mostly decompensation effect with less favorable dynamics.

    Pincus, Aaron L; Lukowitsky, Mark R

    2010-01-01

    We review the literature on pathological narcissism and narcissistic personality disorder (NPD) and describe a significant criterion problem related to four inconsistencies in phenotypic descriptions and taxonomic models across clinical theory, research, and practice; psychiatric diagnosis; and social/personality psychology. This impedes scientific synthesis, weakens narcissism's nomological net, and contributes to a discrepancy between low prevalence rates of NPD and higher rates of practitioner-diagnosed pathological narcissism, along with an enormous clinical literature on narcissistic disturbances. Criterion issues must be resolved, including clarification of the nature of normal and pathological narcissism, incorporation of the two broad phenotypic themes of narcissistic grandiosity and narcissistic vulnerability into revised diagnostic criteria and assessment instruments, elimination of references to overt and covert narcissism that reify these modes of expression as distinct narcissistic types, and determination of the appropriate structure for pathological narcissism. Implications for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders and the science of personality disorders are presented.

    2014-04-15

    The discharge dynamics in an atmospheric pressure dielectric barrier discharge (DBD) is studied in a DBD reactor consisting of a pair of stainless steel parallel plate electrodes. The DBD discharge has been generated by a 50 Hz ac high voltage power source. The high-speed intensified charge coupled device camera is used to capture the images of filaments occurring in the discharge gap. It is observed that frequent synchronous breakdown of micro discharges occurs across the discharge gap in the case of negative current pulse. The experimental results reveal that secondary emissions from the dielectric surface play a key role in the synchronous breakdown of plasma filaments.

    Full Text Available Introduction: The rising incidence of the impacted mandibular third molars and their association with pathologies is now considered a public health problem. Aims and Objectives: The objective of this study was to assess the position of impacted mandibular third molars that are prone to developing pathologies and to determine the frequency and type of pathological conditions associated with these impacted teeth to facilitate planning for their prophylactic removal. Materials and Methods: Consecutive panoramic radiographs and clinical examination of 300 patients with impacted mandibular third molars were collected. They were segregated according to Pell and Gregory’s classification, Winter’s classification, and according to their state of eruption. These were correlated with associated pathologies based on clinical and radiological criteria. Statistical Analysis Used: Descriptive statistics included computation of percentages, mean, and standard deviations. The statistical test applied for the analysis was Pearson’s Chi-square test (χ2. For this test, confidence interval and P value were set at 93% and ≤0.03, respectively. Results: The pathology most commonly associated with impacted third molars was pericoronitis, which had the highest frequency of occurrence in partially erupted, distoangular, and IA positioned (as per Pell and Gregory classification impacted teeth. Impacted mandibular third molars, which were in IA position, placed mesially, and partially erupted, were prone to develop pathologies such as dental caries and periodontitis. Conclusion: The clinical and radiographical features of impacted third molar may be correlated to the development of their pathological complications. The partially impacted mandibular third molars with mesioangularly aligned in IA position have the highest potential to cause pathological complications.

    In 20 out of 28 patients with pathological reflux, decreased reflux intensity was found in the functional scintiscan after i.v. injection of 10 mg Bromoprid. This way, reflux cases in which successful therapy with so-called motility-influencing substances is highly probable can be identified already during primary diagnosis. In two thirds of all patients with affected oesophagus and pathological reflux accompanying sclerodermatitis, the lower oesophagal sphincter still responded to Bromoprid.

    To report on an analysis on the concept of 'readiness for hospital discharge'. No uniform operational definition of 'readiness for hospital discharge' exists in the literature; therefore, a concept analysis is required to clarify the concept and identify an up-to-date understanding of readiness for hospital discharge. Clarity of the concept will identify all uses of the concept; provide conceptual clarity, an operational definition and direction for further research. Literature review and concept analysis. A review of literature was conducted in 2016. Databases searched were: Academic Search Complete, CINAHL Plus with Full Text, PsycARTICLES, Psychology and Behavioural Sciences Collection, PsycINFO, Social Sciences Full Text (H.W. Wilson) and SocINDEX with Full Text. No date limits were applied. Identification of the attributes, antecedents and consequences of readiness for hospital discharge led to an operational definition of the concept. The following attributes belonging to 'readiness for hospital discharge' were extracted from the literature: physical stability, adequate support, psychological ability, and adequate information and knowledge. This analysis contributes to the advancement of knowledge in the area of hospital discharge, by proposing an operational definition of readiness for hospital discharge, derived from the literature. A better understanding of the phenomenon will assist healthcare professionals to recognize, measure and implement interventions where necessary, to ensure patients are ready for hospital discharge and assist in the advancement of knowledge for all professionals involved in patient discharge from hospital. © 2017 John Wiley & Sons Ltd.

    Radiation characteristics and discharge performances of an excimer lamp are described. The discharge of the HCl/Xe gas mixture at an atmospheric pressure, occurring near the quartz tube wall, is initiated by a trigger wire. A maximum total UV energy of about 0.4 J in a (0.8-0.9) {mu}s pulse, radiated from a 10 cm discharge length, is obtained with a total discharge input energy of 8 J. Excimer lamps are the preferred choice for medical and material processing irradiations, when the monochromaticity or coherence of UV light is not required, due to their low cost, reliability and easy maintenance.

    The primary aim of this study was to investigate eating disorder (ED) pathology in those living with food insecurity. A secondary aim was to investigate whether any-reason dietary restraint, weight self-stigma, and worry increased as level of food insecurity increased. Participants (N = 503) seeking food from food pantries completed questionnaires assessing level of food insecurity, demographics, ED pathology, dietary restraint, weight self-stigma, and worry. Consistent with hypotheses, participants with the highest level of food insecurity (i.e., adults who reported having hungry children in their household) also endorsed significantly higher levels of binge eating, overall ED pathology, any-reason dietary restraint, weight self-stigma, and worry compared to participants with lower levels of food insecurity. Contrary to hypotheses, compensatory behaviors also increased as level of food insecurity worsened. Overall, 17% of those in the child hunger food insecurity group reported clinically significant ED pathology. This is the first study to assess the full spectrum of ED pathology in a low-income, marginalized population with food insecurity. Given that food insecurity is a global concern, results from this study suggest that greater attention to the association between ED pathology and food insecurity is warranted by researchers around the world. © 2017 Wiley Periodicals, Inc.

  17. Determining customer satisfaction in anatomic pathology.

    Zarbo, Richard J

    2006-05-01

    Measurement of physicians' and patients' satisfaction with laboratory services has become a standard practice in the United States, prompted by national accreditation requirements. Unlike other surveys of hospital-, outpatient care-, or physician-related activities, no ongoing, comprehensive customer satisfaction survey of anatomic pathology services is available for subscription that would allow continual benchmarking against peer laboratories. Pathologists, therefore, must often design their own local assessment tools to determine physician satisfaction in anatomic pathology. To describe satisfaction survey design that would elicit specific information from physician customers about key elements of anatomic pathology services. The author shares his experience in biannually assessing customer satisfaction in anatomic pathology with survey tools designed at the Henry Ford Hospital, Detroit, Mich. Benchmarks for physician satisfaction, opportunities for improvement, and characteristics that correlated with a high level of physician satisfaction were identified nationally from a standardized survey tool used by 94 laboratories in the 2001 College of American Pathologists Q-Probes quality improvement program. In general, physicians are most satisfied with professional diagnostic services and least satisfied with pathology services related to poor communication. A well-designed and conducted customer satisfaction survey is an opportunity for pathologists to periodically educate physician customers about services offered, manage unrealistic expectations, and understand the evolving needs of the physician customer. Armed with current information from physician customers, the pathologist is better able to strategically plan for resources that facilitate performance improvements in anatomic pathology laboratory services that align with evolving clinical needs in health care delivery.

    Some neurochemical evidence as well as recent studies on molecular genetics suggest that pathologic gambling may be related to dysregulated dopamine neurotransmission. The current study examined sensory (motor) gating in pathologic gamblers as a putative measure of endogenous brain dopamine activity with prepulse inhibition of the acoustic startle eye-blink response and the auditory P300 event-related potential. Seventeen pathologic gamblers and 21 age- and gender-matched healthy control subjects were assessed. Both prepulse inhibition measures were recorded under passive listening and two-tone prepulse discrimination conditions. Compared to the control group, pathologic gamblers exhibited disrupted sensory (motor) gating on all measures of prepulse inhibition. Sensory motor gating deficits of eye-blink responses were most profound at 120-millisecond prepulse lead intervals in the passive listening task and at 240-millisecond prepulse lead intervals in the two-tone prepulse discrimination task. Sensory gating of P300 was also impaired in pathologic gamblers, particularly at 500-millisecond lead intervals, when performing the discrimination task on the prepulse. In the context of preclinical studies on the disruptive effects of dopamine agonists on prepulse inhibition, our findings suggest increased endogenous brain dopamine activity in pathologic gambling in line with previous neurobiological findings.

    Full Text Available Introduction: Successful implementation of whole slide imaging (WSI for routine clinical practice has been accomplished in only a few pathology laboratories worldwide. We report the transition to an effective and complete digital surgical pathology workflow in the pathology laboratory at Cannizzaro Hospital in Catania, Italy. Methods: All (100% permanent histopathology glass slides were digitized at ×20 using Aperio AT2 scanners. Compatible stain and scanning slide racks were employed to streamline operations. eSlide Manager software was bidirectionally interfaced with the anatomic pathology laboratory information system. Virtual slide trays connected to the two-dimensional (2D barcode tracking system allowed pathologists to confirm that they were correctly assigned slides and that all tissues on these glass slides were scanned. Results: Over 115,000 glass slides were digitized with a scan fail rate of around 1%. Drying glass slides before scanning minimized them sticking to scanner racks. Implementation required introduction of a 2D barcode tracking system and modification of histology workflow processes. Conclusion: Our experience indicates that effective adoption of WSI for primary diagnostic use was more dependent on optimizing preimaging variables and integration with the laboratory information system than on information technology infrastructure and ensuring pathologist buy-in. Implementation of digital pathology for routine practice not only leveraged the benefits of digital imaging but also creates an opportunity for establishing standardization of workflow processes in the pathology laboratory.

  20. What Controls Submarine Groundwater Discharge?

    Martin, J. B.; Cable, J. E.; Cherrier, J.; Roy, M.; Smith, C. G.; Dorsett, A.

    Numerous processes have been implicated in controlling submarine groundwater discharge (SGD) to coastal zones since Ghyben, Herzberg and Dupuit developed models of fresh water discharge from coastal aquifers at the turn of the 19th century. Multiple empirical and modeling techniques have also been applied to these environments to measure the flow. By the mid-1950's, Cooper had demonstrated that dispersion across the fresh water-salt water boundary required salt water entrained into fresh water flow be balanced by recharge of salt water across the sediment-water interface seaward of the outflow face. Percolation of water into the beach face from wind and tidal wave run up and changes in pressure at the sediment-water interface with fluctuating tides have now been recognized, and observed, as processes driving seawater into the sediments. Within the past few years, variations in water table levels and the 1:40 amplification from density difference in fresh water and seawater have been implicated to pump salt water seasonally across the sediment- water interface. Salt water driven by waves, tides and seasonal water table fluctuations is now recognized as a component of SGD when it flows back to overlying surface waters. None of these processes are sufficiently large to provide measured volumes of SGD in Indian River Lagoon, Florida, however, because minimal tides and waves exist, flat topography and transmissive aquifers minimize fluctuations of the water table, and little water is entrained across the salt water-fresh water boundary. Nonetheless, the saline fraction of SGD represents more than 99% of the volume of total SGD in the Indian River Lagoon. This volume of saline SGD can be driven by the abundance of burrowing organisms in the lagoon, which pump sufficient amounts of water through the sediment- water interface. These bioirrigating organisms are ubiquitous at all water depths in sandy sediment and thus may provide one of the major sources of SGD world wide

    A discharge lamp includes an envelope, a fill which emits light when excited disposed in the envelope, a source of excitation power coupled to the fill to excite the fill and cause the fill to emit light, and a reflector disposed around the envelope and defining an opening, the reflector being configured to reflect some of the light emitted by the fill back into the fill while allowing some light to exit through the opening. The reflector may be made from a material having a similar thermal index of expansion as compared to the envelope and which is closely spaced to the envelope. The envelope material may be quartz and the reflector material may be either silica or alumina. The reflector may be formed as a jacket having a rigid structure which does not adhere to the envelope. The lamp may further include an optical clement spaced from the envelope and configured to reflect an unwanted component of light which exited the envelope back into the envelope through the opening in the reflector. Light which can be beneficially recaptured includes selected wavelength regions, a selected polarization, and selected angular components.

  3. Fluid jet electric discharge source

    Bender, Howard A [Ripon, CA

    2006-04-25

    A fluid jet or filament source and a pair of coaxial high voltage electrodes, in combination, comprise an electrical discharge system to produce radiation and, in particular, EUV radiation. The fluid jet source is composed of at least two serially connected reservoirs, a first reservoir into which a fluid, that can be either a liquid or a gas, can be fed at some pressure higher than atmospheric and a second reservoir maintained at a lower pressure than the first. The fluid is allowed to expand through an aperture into a high vacuum region between a pair of coaxial electrodes. This second expansion produces a narrow well-directed fluid jet whose size is dependent on the size and configuration of the apertures and the pressure used in the reservoir. At some time during the flow of the fluid filament, a high voltage pulse is applied to the electrodes to excite the fluid to form a plasma which provides the desired radiation; the wavelength of the radiation being determined by the composition of the fluid.

    This paper describes a novel and simple concept of plasma source, which is able to produce a radiofrequency magnetized discharge with minimal power requirements. The source is based on the magnetron concept and uses a permanent magnet as an active electrode. The dipolar field produced by the magnet confines the electrons, which cause further ionization, thus producing a toroidally shaped plasma in the equatorial region around the electrode. A plasma can be ignited with such scheme with power levels as low as 5 W. Paschen curves have been built for four different working gases, showing that in Helium or Neon, plasma breakdown is easily obtained also at atmospheric pressure. The plasma properties have been measured using a balanced Langmuir probe, showing that the electron temperature is around 3–4 eV and higher in the cathode proximity. Plasma densities of the order of 10{sup 16 }m{sup −3} have been obtained, with a good positive scaling with applied power. Overall, the electron pressure appears to be strongly correlated with the magnetic field magnitude in the measurement point.

    We aimed to investigate eating disorder pathology in German elite adolescent athletes. Evidence suggests that eating disorder pathology is more common in adult elite sports, especially in female athletes and in sports emphasizing leanness. There is a scarcity of studies in elite adolescent athletes who are in a vulnerable developmental stage and are affected by general as well as sport-specific risk factors. Our data was derived from the German Young Olympic Athletes' Lifestyle and Health Management Study (GOAL) which conducted a survey in 1138 elite adolescent athletes. In this sample, we assessed body weight, weight control behavior, body acceptance and screened overall for core symptoms of eating disorders, depression and anxiety. We performed a tree analysis to identify high risk groups for eating disorder pathology. High risk groups comprised (a) athletes competing in weight dependent sports, and among athletes competing in disciplines other than weight dependent sports (b) athletes who are high on negative affectivity, (c) female athletes and (d) male athletes competing in endurance, technical or power sports. Athletes competing in weight dependent disciplines reported wide spread use of compensatory behaviors to influence body weight. Athletes reporting eating disorder pathology showed higher levels of depression and anxiety than athletes without eating disorder pathology. Increased psychosocial burden in athletes with eating disorder pathology suggests that eating disorder symptoms should not be accepted as an unproblematic and functional part of elite sports. The prevention and management of eating disorder pathology is especially important in weight dependent sports. © 2016 Wiley Periodicals, Inc.

    Digital pathology is becoming technically possible to implement for routine pathology work. At our institution, we have been using digital pathology for second opinion intraoperative consultations for over 10 years. Herein, we describe our experience in converting to a digital pathology platform for primary pathology diagnosis. We implemented an incremental rollout for digital pathology on subspecialty benches, beginning with cases that contained small amounts of tissue (biopsy specimens). We successfully scanned over 40,000 slides through our digital pathology system. Several lessons (both challenges and opportunities) were learned through this implementation. A successful conversion to digital pathology requires pre-imaging adjustments, integrated software and post-imaging evaluations.

    2017-12-01

    Discharge characteristics of helicon plasma in nitrogen and argon-nitrogen mixtures were investigated experimentally by using a Langmuir probe, a B-dot probe, and an optical emission spectrum. Helicon wave discharge is confirmed by the changes of electron density and electromagnetic signal amplitude with the increasing RF power, which shows three discharge stages in nitrogen, corresponding to E-mode, H-mode, and W-mode discharges in helicon plasma, respectively. Discharge images in the radial cross section at different discharge modes through an intensified charge coupled device (ICCD) show a rapid increase in luminous intensity along with the RF power. When the nitrogen discharge is in the W-mode, the images show that the strongest luminance locates near the plasma boundary and no blue core appears in the axial center of tube, which is always observed in argon W-mode discharge. The "big blue" or blue core is a special character in helicon plasma, but it has not been observed in nitrogen helicon plasma. In nitrogen-argon mixtures, a weak blue core is observed in ICCD images since the nitrogen content is increased. The electric field turns to the periphery in the distribution of the radial field and the electron temperature decreases with the increasing nitrogen content, especially when the blue core disappears. The different behaviors of the electron impact and the energy consumption in nitrogen helicon plasma are suggested to be responsible for the decrease in electron energy and the change in the electric field distribution.

    2016-12-01

    Long-term records of the flow of water through tidal channels are essential to constrain the budgets of sediments and biogeochemical compounds in salt marshes. Statistical models which relate discharge to water level allow the estimation of such records from more easily obtained records of water stage in the channel. While there is clearly structure in the stage-discharge relationship, nonlinearity and nonstationarity of the relationship complicates the construction of statistical stage-discharge models with adequate performance for discharge estimation and uncertainty quantification. Here we compare four different types of stage-discharge models, each of which is designed to capture different characteristics of the stage-discharge relationship. We estimate and validate each of these models on a two-month long time series of stage and discharge obtained with an Acoustic Doppler Current Profiler in a salt marsh channel. We find that the best performance is obtained by models which account for the nonlinear and time-varying nature of the stage-discharge relationship. Good performance can also be obtained from a simplified version of these models which approximates the fully nonlinear and time-varying models with a piecewise linear formulation.

    The aqueous discharges into natural waters is a very technical solution expecially for surface buoyant discharges. It is not only convenient to limit the concentration levels of the discharges, but also to improve the turbolent processes that diluite the discharge. Mostly these processes depend by some geometric parameters of the discharge and by some physical parameters of the effluent and of the receiving water body. An appropriate choice of some parameters, using also suitable mathematical models, allows to design discharges with a very high dilution; so the decreasing of the pollutant levels is improved and the environmental impact can be reduced versus a not diluted effluent. The simulations of a mathematical model, here described, prove that in some circumstances, expecially in case of discharges of fresh water into saline water bodies with a low velocity of the current, the dilution is poor; the effluent can be trapped in a narrow water surface layer where the pollutant concentrations remain high. also far away from the discharge point

  20. Computing discharge using the index velocity method

    Science.gov (United States)

    Levesque, Victor A.; Oberg, Kevin A.

    2012-01-01

    Application of the index velocity method for computing continuous records of discharge has become increasingly common, especially since the introduction of low-cost acoustic Doppler velocity meters (ADVMs) in 1997. Presently (2011), the index velocity method is being used to compute discharge records for approximately 470 gaging stations operated and maintained by the U.S. Geological Survey. The purpose of this report is to document and describe techniques for computing discharge records using the index velocity method. Computing discharge using the index velocity method differs from the traditional stage-discharge method by separating velocity and area into two ratings—the index velocity rating and the stage-area rating. The outputs from each of these ratings, mean channel velocity (V) and cross-sectional area (A), are then multiplied together to compute a discharge. For the index velocity method, V is a function of such parameters as streamwise velocity, stage, cross-stream velocity, and velocity head, and A is a function of stage and cross-section shape. The index velocity method can be used at locations where stage-discharge methods are used, but it is especially appropriate when more than one specific discharge can be measured for a specific stage. After the ADVM is selected, installed, and configured, the stage-area rating and the index velocity rating must be developed. A standard cross section is identified and surveyed in order to develop the stage-area rating. The standard cross section should be surveyed every year for the first 3 years of operation and thereafter at a lesser frequency, depending on the susceptibility of the cross section to change. Periodic measurements of discharge are used to calibrate and validate the index rating for the range of conditions experienced at the gaging station. Data from discharge measurements, ADVMs, and stage sensors are compiled for index-rating analysis. Index ratings are developed by means of regression
