During the pandemic, Mount Pleasant, Texas became a hotspot for Covid-19 cases in the Hispanic community employed by a local meat packing plant and many other industries. An important consideration...

Hepatitis B virus (HBV) is a potentially deadly viral infection that can lead to liver cancer. Many refugee immigrants resettled in the US come from countries known to have a high prevalence of HBV infections. Unfortunately, most infected refugee immigrants are unaware of their HBV status. The disease is highly preventable through a vaccine, but chronic HBV is incurable once the disease has developed. For the purposes of this cross-sectional study, we conducted analysis of data collected through the Building Bridges Initiative (BBI) to assess HBV awareness, vaccination status, screening, and infection among multiethnic, primarily refugee, immigrant populations living in North Texas. Overall, 74% of study participants reported having heard about HBV, but only 31% knew their HBV status. Whereas 69% of study participants lacked awareness about their HBV status and self-reported prevalence of chronic HBV among study participants was 4%. For the vaccine, only 26% reported to have received at least one dose; 53% did not know, while 21% had not ever received it. For those unaware of their HBV status, the BBI offered participants free HBV screening and assistance for vaccination as needed. 76% of participants that accepted HBV screening from BBI were never screened before (enrollment in BBI). Chronic HBV positivity rate for participants was 6%, which is twenty times higher than the national prevalence of chronic HBV (0.3%). High prevalence of HBV, low awareness and low vaccination rates seen in this study highlights the need for increased HBV prevention among foreign born populations.

Overview In 2012, the Institute of Medicine Roundtable on Health Literacy established 10 attributes of a health literate health care organization that, if instated, would improve health information and empower patients to make more informed health decisions. Few studies have assessed how well organizations meet these attributes. Purpose This study sought to describe the extent to which health care systems in North Texas were adopting policies and practices that address the 10 attributes of a health literate health care organization. More specifically, we sought to describe key organizational leaders' and clinicians' perceptions in this regard. Study design and methods This was a mixed-methods study, conducted with a convenience sample of 74 key informants from 13 hospitals across five health care systems. Informants provided demographic data, and their perceptions of the extent to which their hospital met the 10 attributes were measured via the Health Literate Health Care Organization 10-item questionnaire (HLHO-10) and semistructured interviews. Results Mean scores for HLHO-10 items ranged from 3.74 to 5.39, with 7 as a maximum score. Qualitative data provided richer content, elaborating on the survey results. Workforce training in health literacy, patient inclusion in health information development and evaluation, and communication about health care costs were rated the lowest and were described as issues of concern. Conclusion Study findings indicated limited leadership and little systemic promotion of efforts to ensure health literate health care organizations, although individual health literacy champions sometimes stepped up with creative initiatives.

BACKGROUND: Enteral tubes are prevalent among children with medical complexity (CMC), and complications can lead to costly health care use. Our objective was to design and test the usability of a mobile application (app) to support family-delivered enteral tube care. METHODS: Human-centered design methods (affinity diagramming, persona development, and software development) were applied with family caregivers of CMC to develop a prototype. During 3 waves of usability testing with design refinement between waves, screen capture software collected user-app interactions and inductive content analysis of narrative feedback identified areas for design improvement. The National Aeronautics and Space Administration Task Load Index and the System Usability Scale quantified mental workload and ease of use. RESULTS: Design participants identified core app functions, including displaying care routines, reminders, tracking inventory and health data, caregiver communication, and troubleshooting. Usability testing participants were 80% non-Hispanic white, 28% lived in rural settings, and 20% had not completed high school. Median years providing enteral care was 2 (range 1–14). Design iterations improved app function, simplification, and user experience. The mean System Usability Scale score was 76, indicating above-average usability. National Aeronautics and Space Administration Task Load Index revealed low mental demand, frustration, and effort. All 14 participants reported that they would recommend the app, and that the app would help with organization, communication, and caregiver transitions. CONCLUSIONS: Using a human-centered codesign process, we created a highly usable mobile application to support enteral tube caregiving at home. Future work involves evaluating the feasibility of longitudinal use and effectiveness in improving self-efficacy and reduce device complications.

Necrotizing fasciitis is an aggressive, life threatening soft tissue infection that requires high index of suspicion for diagnosis. Diagnosis is clinical with management including broad spectrum antibiotics and emergent operative debridement. The majority of cases are secondary to underlying medical processes, local tissue damage, abscess, or inciting procedure, with a paucity of data correlating causation with colon cancer. We describe the case of an 84-year-old man presenting with sepsis of unknown origin who was diagnosed with an atypical presentation of necrotizing fasciitis secondary to a perforated cecal malignancy. His case is unique in that a less virulent polymicrobial infection was likely involved as he initially improved with conservative management alone. He ultimately declined and expired secondary to overwhelming sepsis from his infection. This case highlights the importance of maintaining a high index of suspicion for necrotizing infection and considerations for alternative etiologies of infection including perforated malignancies.

The association of thrombotic microangiopathy (TMA) with systemic lupus erythematosus (SLE) has been described in 0.5 to 10% of cases, and patients present worse outcome. TMA is described as the association of microangiopathic hemolytic anemia, thrombocytopenia, and an organ injury, frequently the kidney. This study describes a successful case of use of eculizumab in a patient with SLE and TMA refractory to standard therapy, and provides a literature review. Case description and search in PubMed and MEDLINE using systemic lupus erythemathous and/or antiphospholipid syndrome (APS) and eculizumab retrieved 15 case reports. Eighteen-year-old female presented acute renal failure and TMA and was diagnosed with SLE. Steroids and IV cyclophosphamide were started together with plasma exchange. After 55 days, she still persisted with microangiopathic anemia, thrombocytopenia, and anuria, and eculizumab was introduced. She had rapid improvement in hematological parameters, and dialysis was discontinued 25 days after the first dose. Genetic analysis showed large heterozygous deletion encompassing the entire CFHR1 and CFHR3, a finding previously associated with patients presenting atypical hemolytic-uremic syndrome (aHUS). Twenty patients who received eculizumab with SLE and/or APS have been published to date: 11 were female and mean age at presentation was 31 years. Seven out of the 20 patients presented only SLE, 5 patients only APS and 8 patients both SLE and APS. Eighteen patients underwent plasma exchange, with a mean of 20 (4-120) sessions per patient. Thirteen patients received rituximab. Hematological response was evident in 100% and kidney recovery in 85% of patients. The terminal complement blockade with eculizumab is an optional treatment for patients with SLE and/or APS presenting TMA and refractory to current immunosuppression therapies. Genetic testing may help recognize patients with aHUS and SLE/APS and therefore help to determine length of treatment with eculizumab.

As more individuals turn to the Internet for health-related information and technology increases the availability and use of implantable medical devices (IMDs), the websites marketing these devices will increase. Healthy People 2020 mandates increased understandability and usability of health-related websites. This project used social cognitive theory (SCT) and health literacy constructs from the Institute of Medicine and National Institutes of Health to analyze eight IMD websites. Despite current recommendations, none of the websites considered for this study offered content of an appropriate reading level in conjunction with the United States average of eighth grade, and 75% of the sites failed to satisfy more than one health literacy construct. Most of the websites lacked many of the SCT constructs. More attention is needed to improve the usability of these and future IMD websites to simultaneously meet the goal of marketing IMDs and the Healthy People 2020 goals to educate patients and promote public health.

Polymyositis (PM) and dermatomyositis (DM) are very rare connective tissue disorders which only in exceptional circumstances affect white men. The present paper describes the case of an obese 55-years-old man in whom no muscular-skeletal system symptoms were found during the period of 2 years before the onset of arthritis, and who was treated because of cardiac involvement (pericarditis, PAF), pleuritis, malaise and fever. Only the occurrence of non erosive arthritis decided on the connective tissue disorder as a cause of his complaints. Previously the diagnostics was based on the exclusion of malignant diseases and bacterial and viral infections. The determination of antinuclear antibodies in high titer without any specific, typical of individual disease entities antinuclear antibodies allowed only the diagnose of undifferentiated connective tissue disease. Glucocorticosteroid treatment was initiated, however six months later despite treatment with metyloprednisolone the symptoms and signs associated with PM accompanied by high level of creatinophosphokinase and elevated transaminase were found. The muscle biopsy revealed myositis, but no specific antibodies, especially anti-Jo-1, were detected. It is very interesting that cyclophosphamide + glucocorticoids pulse therapy failed to prevent the development of antiphospholipide syndrome and interstitial pulmonary fibrosis in the PM patient. Overlapping of immunological tissue disorders is a well-known phenomenon, but in the case of fulminating and distinct symptoms and signs the lack of detection of specific antibodies is quite uncommon.

Approximately 12 million women worldwide use the levonorgestrel-releasing intrauterine system (IUS), with approximately 180,000 users of this IUS currently reported in Austria. A patient satisfaction study of 591 women in Austria revealed a high number of 'very satisfied' (79%) and 'satisfied' (19%) patients. Reliability, comfort, excellent compatibility and less severe, shorter and less painful monthly periods were the most frequently named advantages of the levonorgestrel-releasing IUS. Medication-induced cervical priming before insertion can be carried out on a routine or selective basis (for example in nullipara, in women who have undergone cervical conisation or in women who have previously experienced painful insertion). There is, at present, no evidence of an increased rate of breast cancer through use of the levonorgestrel-releasing IUS. A directly comparative study with oral contraceptives in young nullipara showed excellent results for the levonorgestrel-releasing IUS, with no perforations, inflammation or pregnancies.

Purpose To evaluate the rate of prophylactic contralateral mastectomy in an international cohort of women with hereditary breast cancer and to evaluate the predictors of uptake of preventive surgery. Patients and Methods Women with a BRCA1 or BRCA2 mutation who had been diagnosed with unilateral breast cancer were followed prospectively for a minimum of 1.5 years. Information was collected on prophylactic surgery, tamoxifen use, and the occurrence of contralateral breast cancer. Results Nine hundred twenty-seven women were included in the study; of these, 253 women (27.3%) underwent a contralateral prophylactic mastectomy after the initial diagnosis of breast cancer. There were large differences in uptake of contralateral prophylactic mastectomy by country, ranging from 0% in Norway to 49.3% in the United States. Among women from North America, those who had a prophylactic contralateral mastectomy were significantly younger at breast cancer diagnosis (mean age, 39 years) than were those without preventive surgery (mean age, 43 years). Women who initially underwent breast-conserving surgery were less likely to undergo contralateral prophylactic mastectomy than were women who underwent a mastectomy (12% v 40%; P < 10−4). Women who had elected for a prophylactic bilateral oophorectomy were more likely to have had their contralateral breast removed than those with intact ovaries (33% v 18%; P < 10−4). Conclusion Age, type of initial breast cancer surgery, and prophylactic oophorectomy are all predictive of prophylactic contralateral mastectomy in women with breast cancer and a BRCA mutation. The acceptance of contralateral preventive mastectomy was much higher in North America than in Europe.

Mutations in the BRCA1 or BRCA2 genes result in a significantly increased risk of breast and ovarian cancer. Austrian women who carry a BRCA1 mutation have a risk of 85% for breast cancer and 53% for ovarian cancer up to 70 years of age. At-risk women have 2 medical options: closely monitored early detection using mammography, breast ultrasound, and MRI, as well as tumor markers and vaginal ultrasound, or real risk reduction through prophylactic removal of the breast tissue and/or the ovaries. As awareness of such a high risk of disease may cause a great deal of distress, and because prophylactic surgeries offer only very drastic measures for risk reduction, a special multidisciplinary care concept is of particular importance. This care starts with comprehensive genetic counseling before performing molecular genetic analysis and must be continued after a genetic predisposition for breast and ovarian cancer has been identified. Right from the start, special schooling in Austria has ensured that patients in all cooperating genetic counseling centers are counseled, selected, and followed- up according to the same criteria.

Purpose The purpose of this study was to estimate the extent of protection offered against breast cancer by prophylactic oophorectomy in carriers of BRCA1 or BRCA2 mutations and to determine to what extent risk reduction varies with age at oophorectomy, age at diagnosis, and time elapsed since surgery. Patients and Methods We analyzed 1,439 patients with breast cancer and 1,866 matched controls derived from a registry of BRCA1 and BRCA2 carriers. We estimated odds ratios (ORs) of breast cancer for having had a bilateral oophorectomy, using conditional logistic regression, matched for parity and for oral contraceptive use. Results A previous history of oophorectomy was associated with a significant reduction in breast cancer risk of 56% for BRCA1 carriers (OR = 0.44; 95% CI, 0.29 to 0.66) and of 46% for BRCA2 carriers (OR = 0.57; 95% CI, 0.28 to 1.15). The risk reduction was greater if the oophorectomy was performed before age 40 (OR = 0.36; 95% CI, 0.20 to 0.64 for BRCA1 carriers) than after age 40 (OR = 0.53; 95% CI, 0.30 to 0.91). The protective effect was evident for 15 years post-oophorectomy (OR = 0.39; 95% CI, 0.26 to 0.57). Conclusion Oophorectomy is an effective means of reducing the risk of breast cancer in carriers of BRCA1 mutations. The data suggest oophorectomy is protective in BRCA2 carriers as well, but needs to be confirmed in other studies.

PURPOSE To report the false-negative rate, sensitivity, and specificity of 14-gauge ultrasound-guided large-core needle biopsy (14-G USSB) performed on breast lesions at our institution and, furthermore, to compare and discuss our own results with those reported in the literature. MATERIALS AND METHODS This study includes 399 lesions examined by 14-G USSB. The results of the 14-G USSB were compared with the results of the surgical biopsy or, in cases of benign histology, were followed clinically. A key word search in two medical databases was undertaken to compare our data with those reported in the literature. The search was limited to the period from January 1990 to February 2002 and only original investigations published in English and German were included in our comparison. RESULTS At our institution, 238 (59.6 %) benign and 161 (40.4 %) malignant lesions were diagnosed by 14-G USSB. The 14-G USSB was false-negative in 5 (1.25 %) of 399 cases. It has a sensitivity of 95.7 %, and specificity 100%. The literature reports false-negative rates between 0 % and 1.26 %, sensitivities between 86% and 100%, and specificities between 99.7 % and 100 %. On the basis of 3880 results from seven selected original papers and our own study, the false-negative rate for 14-G USSB was calculated to be 0.4 % (16 of 3880). CONCLUSION Based on our results and those reported in the literature, 14-G USSB can be considered safe and reliable in the assessment of breast lesions.

The aim of our study was to determine the false-negative rate of stereotactic 11-gauge vacuum-assisted biopsy in a validation study of lesions that had subsequent surgical excision.Retrospective review was performed of 318 lesions that underwent stereotactic 11-gauge vacuum-assisted biopsy and subsequent surgical excision. A false-negative case was defined as a pathologically proven cancer in which stereotactic biopsy yielded benign results without atypia. Medical records, imaging studies, and histologic findings were reviewed.False-negative findings were encountered at stereotactic 11-gauge vacuum-assisted biopsy in 3.3% (7/214) of pathologically proven cancers. False-negative findings occurred in 3.5% (4/115) of malignant calcification lesions versus 3.0% (3/99) of malignant masses (p = 1.0). The seven false-negative findings included five Breast Imaging Reporting and Data System (BI-RADS) category 5 lesions that yielded benign results at biopsy, one BI-RADS category 4 mass that benign breast tissue, and one BI-RADS category 4 cluster of calcifications in which no calcifications were retrieved. The false-negative rate was 10.0% (6/60) for radiologists who performed 15 or fewer previous stereotactic vacuum-assisted biopsy procedures versus 0.6% (1/154) for radiologists who performed more than 15 previous stereotactic vacuum-assisted biopsy procedures (p = 0.002).Stereotactic 11-gauge vacuum-assisted biopsy had a false-negative rate of 3.3% that diminished to 0.6% with experience. All false-negative findings could be prospectively identified because of failure to sample calcifications or imaging-histologic discordance.

OBJECTIVES To compare quality of harvested tissue, false-negative rate, and complication rate of large-core needle breast biopsy (LCNBB) and directional, vacuum-assisted breast biopsy (DVABB) in non-palpable breast lesions. PATIENTS AND METHODS From 1994 to 1999, in 580 non-palpable breast lesions a stereotactically-guided breast biopsy was performed. 14-G LCNBB was used in 168 lesions (29 %). DVABB was used in 412 lesions (71 %; 11-G DVABB: 134 lesions 32.5 %, 14-G DVABB: 278 lesions 67.5 %). Following biopsy, patients underwent either surgical excision (n = 533; 93.8 %) or mammographical follow-up (n = 36; 6.2 %). Histological results of LCNBB, DVABB, surgical breast biopsy and follow-up results were compared and scored for their tissue quality on a three-point scale (1 = disagreement between biopsy and surgery; 2 = partial agreement; 3 = complete agreement). In addition, we determined the false negative and complication rate for both systems. RESULTS Histological examination after surgery and follow-up proved 262 (45.2 %) to be benign, 15 (2.6 %) to be high-risk lesions and 303 (52.5 %) to be malignant. In the tissue quality there was no significant difference between 14-G LCNBB (score = 2.94), 11-G DVABB (score = 2.92) and 14-G DVABB (score = 2.91) (p > 0.05). Particularly, in calcifications 11-G DVABB scored better (score = 2.92) than 14-G DVABB (score = 2.88) (p > 0.05). 14-G LCNBB had a lower false negative rate (1.8 %) than 11-G DVABB (3 %) and 14-G DVABB (3.2 %) (p > 0.05). There was no difference in the complication rate between the different needle types. CONCLUSIONS Our results indicate that both LCNBB and DVABB are reliable and safe techniques in the diagnosis of non-palpable breast lesions. However, the use of 14-G LCNBB seems to be advantageous in masses, the use of 11-G DVABB seems to be advantageous in asymmetric densities and calcifications.

The intent of this study was to evaluate the effect that an awareness of being a BRCA1 or BRCA2 mutation carrier has on the attitude towards prophylactic surgery and on developing depression symptoms. Thirty-five families were selected on the basis of previously detected BRCA1 or 2 mutations and 90 family members were given the appropriate questionnaires. Prophylactic mastectomy (PM) was considered by 21% of the Austrian mutation carriers (29% affected and 8% non-affected carriers). The majority of affected and non-affected carriers expected PM to impair the quality of their life. Fifty per cent would undergo prophylactic oophorectomy (53% affected and 46% non-affected carriers). The self-rating depression scale indicated that following mutation result disclosure the depression scores of carriers decreased (40 baseline vs 38 after result disclosure, P = 0.3), whereas, for non-carriers, scores increased (36 baseline vs 40 after result disclosure, P = 0.05). We conclude that information about carrier status is not associated with increased depression symptoms in mutation carriers. In non-carriers, depression scores increased slightly, probably reflecting survivor guilt. The option of having PM was associated with a negative impact on the quality of life and was declined by the majority of Austrian mutation carriers.

Women with BRCA1 or BRCA2 mutation are often advised to undergo preventive oophorectomy. The effectiveness of this intervention has not been prospectively evaluated in a large cohort.To estimate the incidence of ovarian, fallopian tube, and primary peritoneal cancer in women who carry a deleterious mutation in BRCA1 or BRCA2. To estimate the reduction in risk of these cancers associated with a bilateral prophylactic salpingo-oophorectomy.Women known to carry a BRCA1 or BRCA2 mutation were identified from an international registry between 1992 and 2003. A total of 1828 carriers at 1 of 32 centers in Canada, the United States, Europe, and Israel completed questionnaires at baseline and follow-up. Participants were observed from the date of study entry until: diagnosis of ovarian, fallopian tube, or peritoneal cancer; death; or the date of the most recent follow-up.Participants were divided into women who had undergone bilateral prophylactic oophorectomy and those who had not.The incidence of ovarian, peritoneal, and fallopian tube cancer was determined by survival analysis. The risk reduction associated with prophylactic salpingo-oophorectomy was evaluated by a time-dependent survival analysis, adjusting for covariates.After a mean follow-up of 3.5 years, 50 incident ovarian, fallopian tube, and peritoneal cancer cases were reported in the cohort. Of the 1828 women, 555 (30%) underwent a bilateral prophylactic salpingo-oophorectomy prior to study entry, 490 (27%) underwent the procedure after entering the study, and 783 (43%) did not undergo the procedure. There were 32 incident cancers diagnosed in women with intact ovaries (1015/100,000 per year). Eleven cancer cases were identified at the time of prophylactic oophorectomy and 7 were diagnosed following prophylactic oophorectomy (217/100,000 per year). The estimated cumulative incidence of peritoneal cancer is 4.3% at 20 years after oophorectomy. The overall (adjusted) reduction in cancer risk associated with bilateral oophorectomy is 80% (multivariate hazard ratio = 0.20; 95% confidence interval, 0.07-0.58; P = .003).Oophorectomy is associated with reduced risk of ovarian and fallopian tube cancer in high-risk women, although there is a substantial residual risk for peritoneal cancer in BRCA1 and BRCA2 mutation carriers following prophylactic salpingo-oophorectomy.

Background Mutations in brca1 and 2 genes lead to a significant increase in the lifetime risk of developing breast (BC) and ovarian cancer (OC). There are indications that birth cohort can influence the cancer risk in brca1 mutation carriers. Therefore, we investigated the risks for BC and OC associated with brca2 mutations in a cohort of female mutation carriers of a genetically heterogeneous Central European population. Patients and methods This study included 246 women in whom a functional mutation in the brca2 gene had been identified at our institution. At the time of analysis, 153 women had developed cancer (142 BC, 9 OC, 2 BC and OC). Risks were estimated using the product limit method. The log rank test was used to compare different strata. Results After correction for risk-reducing surgeries, the cumulative risk of developing cancer to age 70 was found to be 88% for BC (95% CI 81–95%) and 31% for OC (95% CI 17–45%). Female brca2 mutation carriers born in 1958 or later were at a significantly higher risk of developing BC at a younger age (p Conclusion The age cohort-dependent early onset in BC in women born after 1958 strongly suggests the importance of exogenous factors such as lifestyle modification while this does not seem to be the case for OC. Female brca2 mutation carriers should be counseled about their age cohort-dependent breast cancer risk.

Immigration plays a major role in obstetrics in Austria, and about 18 % of the Austrian population are immigrants. Therefore, we aimed to (1) test the feasibility of a proposed questionnaire for assessment of migrant status in epidemiological research and (2) assess some important associations between procedures and outcomes in obstetrics and migration in selected departments in Austria.We adapted a standardized questionnaire to the main immigration groups in Austria. Information on country of origin, length of residence in Austria and German-language ability was collected from eight selected obstetrics departments. Of the 1,971 questionnaires, 1,873 questionnaires of singleton births were selected and included in the analysis.We analyzed a total of 1,873 parturients with singleton births, of which 35 % had migrant status, 12 % were from ex-Yugoslavia, 12 % were from Turkey, and 12 % were from other countries. The proportion of parturients having their first care visit after the 12th week of pregnancy was higher in migrant groups (19 %). Smoking was highest in the migrants from ex-Yugoslavia (21 %). Vaginal delivery was more frequent in migrants from ex-Yugoslavia (78 %) and Turkey (83 %) than in nonmigrants (71 %) and episiotomy was more frequently performed in migrants from other countries. All differences are statistically significant.Administration of a standardized questionnaire for assessment of migrant status in obstetric departments in Austria was shown to be feasible. We assessed differences in obstetric care and outcome and consequently recommend that action should be initiated in Austria toward harmonizing obstetric procedures among the migrant and the nonmigrant groups and toward minimizing risk factors.

We present the case of 23-year-old woman with good living conditions, one year history of ventricular arrhythmia and 6 months history of decreased exercise tolerance, who was found to have dilated cardiomyopathy after aborted sudden death. Endomyocardial biopsy did not show specific findings. Within 3 months she developed profound bradycardia requiring pacemaker implantation and refractory heart failure, treated with heart transplantation. Intense eosinophilic myocarditis was found in the explanted heart. Retrospective analysis of the patient's blood count revealed mild eosinophilia (eosinophil count: 0.86×109/l) on one examination only. Following heart transplantation the patient had persistent eisinophilia (eosinophil count: 0.62×109/l). Although there was no proven parasitic infestation, based on positive family history of Enterobius vermicularis infestation she was treated with broad-spectrum antiparasitic agent: albendazole and her eosinophil count returned to normal values. This case shows that active eosinophilic myocarditis may present clinically as progressive dilated cardiomyopathy with severe involvement of conduction system. Massive myocardial tissue eosinophilia occurred in the setting of mild and transient blood eosinophilia. Favourable outcome following antiparasitic treatment suggests a potential parasitic infestation as a cause of the disease.

Breast diseases in teenage girls are fortunately uncommon, with most presenting masses being benign. The aim of this study was to evaluate the histopathological results of breast lesions excised from adolescent females less than 19 years of age. The authors reviewed the medical and pathology records at the University Hospital of Vienna, Department of Obstetrics and Gynaecology, between 1993 and 2006, retrospectively. All data included the patient age, age of menarche, pregnancy, hormonal contraception, family history of breast cancer, size of the breast lesion and its histopathology following surgery. Thirty-seven female patients with an average age of 16 years (ranging 12–18 years) were operated on for breast tumor and/or discharge. All tumors were palpable. Six patients had bilateral breast masses; thus, 43 breast lesions were evaluated following surgical excision. Surprisingly, breast cancer was found in two cases. Both patients were diagnosed with a noninvasive ductal carcinoma in situ (DCIS) within a fibroadenoma at the age of 16. These are the first reported cases of DCIS found in this young age group. As breast neoplasm was found in two cases, a malignancy rate of 4.7% was observed. The most common histologies were fibroadenoma (n = 27) and fibrocystic disease (n = 4). The incidence of primary breast cancer in adolescent women is low. However, our experience shows the need for compulsory excision of all breast masses and highlighting the importance of histopathological evaluation of all breast tumors including adolescents.

Purpose: To assess the diagnostic accuracy of mammography, ultrasound, and magnetic resonance imaging (MRI) of the breast in the surveillance of women at high risk for breast cancer. Experimental Design: In this prospective comparison study, women at high risk for breast cancer were offered annual surveillance examinations, consisting of mammography, ultrasound, and MRI, at a single tertiary care breast center. The sensitivity and specificity of each modality was based on the histopathologic evaluation of suspicious findings from all modalities plus the detected interval cancers. Results: Three hundred and twenty-seven women underwent 672 complete imaging rounds. Of a total of 28 detected cancers, 14 were detected by mammography, 12 by ultrasound, and 24 by MRI, which resulted in sensitivities of 50%, 42.9%, and 85.7%, respectively (P < 0.01). MRI detected not only significantly more invasive but also significantly more preinvasive cancers (ductal carcinoma in situ). Mammography, ultrasound, and MRI led to 25, 26, and 101 false-positive findings, which resulted in specificities of 98%, 98%, and 92%, respectively (P < 0.05). Thirty-five (35%) of these false-positive findings were atypical ductal hyperplasias, lesions considered to be of premalignant character. Nine (26%) of those were detected by mammography, 2 (6%) with ultrasound, and 32 (91%) with MRI (P < 0.01). Conclusion: Our results show that MRI of the breast improves the detection of invasive cancers, preinvasive cancers, and premalignant lesions in a high-risk population and should therefore become an integral part of breast cancer surveillance in these patients.

Summary Introduction The available literature does not report on infectious factors potentially triggering intra-articular pathology or dysfunction manifest as temporomandibular (TMJ) disorders. Aim of the study To establish the presence of Borrelia burgdorferi spirochaetes in the histopathological material obtained from the intra-articular space by arthroscopy from patients with advanced TMJ disorders. Subjects and methods The histopathological material was obtained intra-articularly from 31 patients by means of arthroscopy; apart from routine H + E staining, the material was additionally examined for the presence of micro-organisms (spirochaetes) by the Warthin–Starry method. Results Seven out of 31 patients presenting with manifesting TMJ dysfunction had spirochaetes detected in the histopathological material; their shape and size resembling B. burgdorferi bacteria. Conclusion This paper is the first to indicate that in borreliosis the infective agent may localize itself to the temporomandibular joint. This observation cannot be ignored when analyzing the pathogenesis of TMJ degeneration especially that tick-borne infections with spirochaetes are definitely more common than it is generally believed.

Purpose Women who carry germline mutations in the BRCA1 and BRCA2 genes are at greatly increased risk of breast cancer (BC). Numerous studies have shown that moderate to high doses of ionizing radiation are a risk factor for BC. Because of the role of the BRCA proteins in DNA repair, we hypothesized that BRCA carriers might be more sensitive to ionizing radiation than women in the general population. Patients and Methods A retrospective cohort study of 1,601 female BRCA1/2 carriers was performed. Risk of breast cancer from exposure to chest x-rays, as assessed by questionnaire data, was analyzed using a weighted Cox proportional hazards model. Results In this cohort, any reported exposure to chest x-rays was associated with an increased risk of BC (hazard ratio [HR] = 1.54; P = .007). This risk was increased in carrier women aged 40 years and younger (HR = 1.97; P < .001) and in women born after 1949 (HR = 2.56; P < .001), particularly those exposed only before the age of 20 years (HR = 4.64; P < .001). Conclusion In our series of BRCA carriers, we detected a relatively large effect on BC risk with a level of radiation exposure that is at least an order of magnitude lower than in previously studied medical radiation–exposed cohorts. Although part of this increase may be attributable to recall bias, the observed patterns of risk in terms of age at exposure and attained age are consistent with those found in previous studies. If confirmed, the results have important implications for the use of x-ray imaging in young BRCA1/2 carriers.

To retrospectively determine the lesion miss rate and false-negative rate of needle-localized open breast biopsy (NLOBB) with stereotactic guidance in a large study population.The ethical review board approved the study; the need for informed consent was waived. A total of 1115 stereotactic NLOBBs performed in 1068 women aged 22-90 years (mean age, 54 years) were tracked to determine outcomes. In cases of malignancy, NLOBB was considered to be diagnostically successful. The mammographic outcomes in all patients with benign results at NLOBB were tracked for at least 2 years. Cases without such mammographic follow-up were cross-referenced with a tumor registry after at least 54 months. The lesion miss rate was based on all malignant lesions and all lesions with long-term mammographic follow-up. Results from all 1115 NLOBBs were used to report the false-negative rate.Of 1115 NLOBBs, 472 (42%) had malignant results. Mammographic follow-up data were available for 535 (83%) of 643 NLOBBs with benign results. Mammographic follow-up revealed 11 lesions that were missed with NLOBB, of which five were malignant and six benign. Thus, the lesion miss rate with NLOBB was 1.1% (11/[472 + 535]). Among the 643 cases, in 108 of them without mammographic follow-up (17%), cross-referencing with a tumor registry did not reveal missed cases of breast carcinoma. The false-negative rate was therefore 1.0% (5/[472 + 5]).On the basis of the results of long-term follow-up, the authors noted a lesion miss rate of 1.1% and a false-negative rate of 1.0%, which indicate that NLOBB with stereotactic guidance is an accurate method for diagnosing breast lesions.

Background: Women with breast cancer and a BRCA mutation have a high risk of developing a contralateral breast cancer. It is generally believed that the two cancers represent independent events. However, the extent of concordance between the first and second tumors with respect to hormone receptor expression and other pathologic features is unknown. Purpose: To determine the degree of concordance of estrogen receptor (ER) status, tumor grade, and histology in tumors from women with bilateral breast cancer and a BRCA mutation. Subjects and Methods: Women with a history of bilateral invasive breast cancers were selected from an international registry of women with BRCA1 or BRCA2 mutations. Medical records were reviewed to document the characteristics of each cancer and the treatments received. Results: Data were available for 286 women with bilateral breast cancer and a BRCA mutation (211 BRCA1; 75 BRCA2). The mean interval between first and second tumor was 5.1 years. The two tumors were concordant more often than expected for ER status (P < 0.0001) and for grade (P < 0.0001), but not for histology (P = 0.55). The ER status of the first tumor was highly predictive of the ER status of the second tumor (odds ratio, 8.7; 95% confidence interval, 3.5-21.5; P < 0.0001). Neither age, menopausal status, oophorectomy nor tamoxifen use was predictive of the ER status of the second tumor. Conclusions: There is strong concordance in ER status and tumor grade between independent primary breast tumors in women with a BRCA mutation. The excess concordance may be due to common risk factors, genetic variation, or the existence of a preneoplastic lesion that is common to both tumors.

The connection between scleroderma and lymphoma is uncommon and its pathogenic relationship is a much debated subject. We describe the case of a patient with mucosa-associated lymphoid tissue lymphoma (MALT) of both parotid glands without clinical signs of Sjogren's syndrome who simultaneously developed scleroderma. Independently of the pathogenic mechanism of these two diseases, it seems very important to emphasize that scleroderma may be the first manifestation of lymphoma.

In an experimental study (in vitro and in vivo) we evaluated the efficacy of various biopsy needles/devices for breast biopsy. In vitro, biopsies of five human cadaveric breast specimens were performed using 33 different needles/devices ranging from 14 to 20-gauge. Of these 33 needles/devices, 22 optimally performing needles were selected for the in vivo study. In the clinical part of the study, 44 breast lesions were randomly biopsied with each of the 22 needles/devices under stereotactic guidance. Tissue specimens were analysed quantitatively and qualitatively. Several automatic long-throw guns (Accent, Asap, Biopty, Magnum) obtained greater tissue areas and had a better histopathologic score than the conventional type of a side-notch needle like Trucut, an aspiration needle like Surecut, or an end-cut needle like Autovac. The automatic long-throw guns performed better than the short-throw Monopty gun. Regardless of needle size (14–20-gauge), breast biopsies should be routinely performed with automated long-throw side-notch guns (Acecut, Asap, Biopty, Magnum).

To assess the feasibility of the coaxial core breast biopsy technique performed under stereotactic and ultrasound (US) guidance in vitro and in vivo.Biopsies were performed in vitro and in vivo with a coaxial technique. In vitro, the true needle-tip deviation was measured with a breast phantom on a stereotactic device with alteration of x and y axes. In vitro US studies were performed to evaluate the optimal technique for harvesting sufficient material for histologic work-up. In 205 patients, coaxial biopsy was performed in 210 suspicious lesions under US (61 lesions) or stereotactic (patient in the sitting position, n = 67; patient in the prone position, n = 82) guidance. In addition, the coaxial system was used for preoperative localization. Surgery and histologic work-up were performed in all cases.In vitro, the true needle-tip deviation was found to be less than indicated on the stereotactic device. A factor was introduced to correct this error. For US guidance, angulation or rotation of the coaxial needle within the lesion proved to be the best technique to increase the size of histologic specimen. Of the 210 lesions, 112 were benign and 98 were malignant. Agreement between biopsy results and final postsurgical histologic analysis was found in 205 cases (98%).The coaxial breast biopsy technique is an accurate, simple, and time-saving method performed under stereotactic or US guidance.

BRCA1 maps to chromosome region 17q21.1, and mutations in this gene predispose strongly to breast and ovarian cancer. It has recently been isolated and previously it was shown to explain approximately 45 % of all breast cancer families and over 80 % of all families in which both breast and ovarian cancer occur. Women, who carry mutations in the BRCA1 gene, have a lifetime risk of 85 % to develop breast cancer and 60% for ovarian cancer. Austrian HBOC families with several breast- and ovarian cancer cases were selected for mutation screening on the basis of positive LOD scores. Mutation sceening was performed by protein truncation test (PTT). Positive findings were then subjected to DNA sequence analysis. In three until now unrelated families the same mutation could be detected. This mutation in exon 11, 2795delAAAG, has not yet been reported before. The frequency of this mutation in the Austrian population will be of further interest.
