[source] Skin Angiosarcoma Arising in an Irradiated Breast: Case-Report and Literature ReviewDERMATOLOGIC SURGERY, Issue 3 2006FAUSTO CATENA MD BACKGROUND Angiosarcoma (AS) is a rare, invasive malignancy originating from endothelial cells caused by many different clinical situations. AS following radiotherapy for breast cancer after conservative surgery is a rare but well-known association. OBJECTIVE The aim of this article is to describe a case of AS after breast conserving surgery and to review the literature to date. RESULTS We report the case of an 84-year-old woman who developed AS four years after she was subjected to quadrantectomy for invasive ductal cancer, followed by 30 tangent field radiotherapy sessions. She presented with a one-month history or red papular skin eruptions on the operated breast. Skin lesions were submitted for biopsy, and they were positive for AS. The patients was subjected to surgical excision of the remaining breast including all AS lesions. She is alive with no evidence of disease after 10 months follow-up. CONCLUSION Post-radiotherapy AS is rare neoplasm, but it should be considered in the case of patients with red lesions after breast conserving surgery and adjuvant radiotherapy. [source] Sebaceous Carcinoma, Basal Cell Carcinoma, Trichoadenoma, Trichoblastoma, and Syringocystadenoma Papilliferum Arising within a Nevus SebaceusDERMATOLOGIC SURGERY, Issue 12p2 2004Christopher J. Miller MD Background. Nevus sebaceus has a well-documented potential to develop a wide variety of neoplasms of both epidermal and adnexal origins. It is highly unusual for more than three tumors to arise simultaneously within a single nevus sebaceus. Sebaceous carcinoma arising within a nevus sebaceus is a rare occurrence. Objective. The objective was to report the case of a patient with a nevus sebaceus that simultaneously developed five distinct neoplasms of epidermal and various adnexal origins and to report the fourth case of sebaceous carcinoma arising within a nevus sebaceus. Methods. A 45-year-old woman presented with a nevus sebaceusthat contained five separate neoplasms, including sebaceous carcinoma, basal cell carcinoma, trichoadenoma, trichoblastoma, and syringocystadenoma papilliferum. Results. Complete excision of the nevus sebaceus and the five tumors was performed. Systemic work-up showed no evidence of metastatic disease or association with Muir-Torre syndrome. Conclusion. This case report highlights the diverse neoplastic potential of nevus sebaceus and demonstrates the capacity of this hamartoma to develop aggressive tumors, such as sebaceous carcinoma. Prophylactic excision or at least close clinical surveillance for sudden development of new growths is warranted in all cases of nevus sebaceus.

[source] An Acute Model for Atrial Fibrillation Arising from a Peripheral Atrial Site: Evidence for Primary and Secondary TriggersJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 5 2008BENJAMIN J. SCHERLAG Ph.D. Background: We previously demonstrated that acetylcholine (Ach) injected into cardiac ganglionated plexi (GP) causes pulmonary vein (PV) ectopy initiating atrial fibrillation (AF). Objective: To determine the effects of Ach applied at non-PV sites. Methods: Overall, 54 dogs were anesthetized with Na-pentobarbital. A right and left thoracotomy allowed the placement of multielectrode catheters to record from the superior PVs, mid portion of the atrium and the atrial appendages (AA). A monophasic action potential (MAP) was recorded from the AA. Ach (1, 10, 100 mM) was applied sequentially to the AA. Results: In 19 of 26 animals, Ach 100 mM on the right (n = 15) or left (n = 4) AA induced focal, sustained AF (,10 minutes) with rapid regular firing (cycle length = 37 ± 7 ms) at the AA. A clamp with teeth placed across the AA caused arrest in the AA. However, AF was sustained only when PV sites adjacent to the GP manifested complex fractionated atrial electrograms (CFAE). Clamping the AA prior to Ach (100 mM) application resulted in focal AF arising at the PVs but not at the AA. When a clamp without teeth was applied prior to Ach application, no AF at either AA or PV site could be induced. Conclusion: Isolation of the focal AF at the AA (primary trigger) by clamping caused cessation of activity in the AA, but AF continued due to secondary triggers arising from PVs. The possible mechanism(s) responsible for these findings are discussed, and various ancillary experiments (n = 28) were added to help elucidate mechanisms. [source] Prevalence and significance of Exit Block During Arrhythmias Arising in Pulmonary VeinsJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 4 2000HUNG-FAT TSE M.D. Exit Block. Introduction: Recent studies described the occurrence of conduction block within pulmonary veins. The purpose of this study was to evaluate the prevalence of exit block during arrhythmias that arise in pulmonary veins. Methods and Results: Twenty-five patients with atrial tachycardia/fibrillation underwent successful ablation of 28 arrhythmogenic foci within a pulmonary vein. The prevalence of exit block in the pulmonary veins was determined in 28 arrhythmogenic pulmonary veins and 40 nonarrhythmogenic pulmonary veins. During isolated premature depolarizations, exit block in a pulmonary vein was observed at 50% of arrhythmogenic pulmonary vein sites and was never observed within pulmonary veins that did not generate a tachycardia (P < 0.01). During tachycardia, exit block from a pulmonary vein was observed in 61% of the arrhythmogenic pulmonary veins. The mean cycle length of the pulmonary vein tachycardias associated with exit block was significantly shorter than the cycle length of tachycardia that were not associated with exit block (163 ± 32 vs 251 ± 45 msec, P < 0.001), Exit block in two pulmonary veins during the same episode of tachycardia was observed in 3 of the 28 arrhythmogenic pulmonary veins (11%) in three different patients. Simultaneous recordings in the two pulmonary veins demonstrated bursts of tachycardia in both veins that were not synchronized. Radiofrequency catheter ablation of the arrhythmogenic site in one of the pulmonary veins eliminated spontaneous recurrences of tachycardia from the other pulmonary vein. Conclusion: Exit block from pulmonary veins is a common observation during tachycardias generated within pulmonary veins and indicates that an arrhythmogenic pulmonary vein has been identified. The occurrence of exit block in more than one pulmonary vein most likely is attributable to simultaneous tachycardias, one or both of which may be tachycardia induced and perpetuated by the other.

[source] Real-time Integration of Intracardiac Echocardiography and Electroanatomic Mapping in PVCs Arising from the LV Anterior Papillary MusclePACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 9 2009Ph.D., TAKUMI YAMADA M.D. A 54-year-old woman with idiopathic premature ventricular contractions (PVCs) underwent electrophysiological testing. Three-dimensional (3D) geometries of the papillary muscles and chamber of the left ventricle (LV) were reconstructed using a CARTO-based 3D ultrasound imaging system (Biosense Webster Inc., Diamond Bar, CA, USA) during the PVCs. Activation mapping in the LV was then performed during the PVCs and the activation map revealed the earliest ventricular activation on the anterior papillary muscle. An irrigated radiofrequency current delivered at that site with guidance from that system eliminated the PVCs. This case may suggest that the guidance system may be feasible and useful for catheter ablation of PVCs arising from uncommon sites. [source] Philosophical Issues Arising from Experimental EconomicsPHILOSOPHY COMPASS (ELECTRONIC), Issue 3 2007Zachary Ernst Human beings are highly irrational, at least if we hold to an economic standard of ,rationality'. Experimental economics studies the irrational behavior of human beings, with the aim of understanding exactly how our behavior deviates from the Homo economicus, as ,rational man' has been called. Insofar as philosophical theories depend upon rationality assumptions, experimental economics is the source of both problems and (at least potential) solutions to several philosophical issues. This article offers a programmatic and highly biased survey of some of these issues, with the hope of convincing the reader that experimental economics is well-deserving of careful study by philosophers. [source] Hesperetin Glucuronide, a Photoprotective Agent Arising from Flavonoid Metabolism in Human Skin Fibroblasts ,PHOTOCHEMISTRY & PHOTOBIOLOGY, Issue 3 2003Anna R. Proteggente ABSTRACT There is considerable interest in the biological properties of flavonoids in terms of their antioxidant and cytoprotective actions. The interaction of the flavanone hesperetin with human skin fibroblasts (FEK4) has revealed the potential for metabolism to hesperetin glucuronide and its subsequent extrusion. As a consequence of this observation, the effectiveness of hesperetin glucuronides, in comparison with that of the aglycone form, in protecting against UV-A radiation has been investigated. The results indicate that hesperetin glucuronides, but not hesperetin, protect against UV-A-induced necrotic cell death.

[source] Consequences Arising From Elevated Surface Temperatures on Human BloodARTIFICIAL ORGANS, Issue 9 2010Kathrin F. Hamilton Abstract Heat in blood pumps is generated by losses of the electrical motor and bearings. In the presented study the influence of tempered surfaces on bulk blood and adhesions on these surfaces was examined. Titanium alloy housing dummies were immersed in 25 mL heparinized human blood. The dummies were constantly tempered at specific temperatures (37,45°C) over 15 min. Blood samples were withdrawn for blood parameter analysis and the determination of the plasmatic coagulation cascade. The quantities of adhesion on surfaces were determined by drained weight. Blood parameters do not alter significantly up to surface temperatures of 45°C. In comparison to the control specimen, a drop in the platelet count can be observed, but is not significantly temperature dependent. The mean mass of adhesions at 41°C increased up to 66% compared to 37°C. Thus, heat generated in electrical motors and contact bearings may influence the amount of adhesions on surfaces. [source] Statistical Issues Arising in the Women's Health InitiativeBIOMETRICS, Issue 4 2005Ross L. Prentice Summary A brief overview of the design of the Women's Health Initiative (WHI) clinical trial and observational study is provided along with a summary of results from the postmenopausal hormone therapy clinical trial components. Since its inception in 1992, the WHI has encountered a number of statistical issues where further methodology developments are needed. These include measurement error modeling and analysis procedures for dietary and physical activity assessment; clinical trial monitoring methods when treatments may affect multiple clinical outcomes, either beneficially or adversely; study design and analysis procedures for high-dimensional genomic and proteomic data; and failure time data analysis procedures when treatment group hazard ratios are time dependent. This final topic seems important in resolving the discrepancy between WHI clinical trial and observational study results on postmenopausal hormone therapy and cardiovascular disease.

[source] Malignant Eccrine Spiradenoma: A Case Report and Review of the LiteratureDERMATOLOGIC SURGERY, Issue 1 2001Masashi Ishikawa MD Background. Eccrine spiradenoma is a well-differentiated benign tumor of the sweat glands. Malignant change arising within eccrine spiradenoma is rare. Objective. We describe a patient with malignant eccrine spiradenoma exhibiting both carcinomatous and sarcomatous differentiation. Methods. Case report and literature review. Results. A 37-year-old woman noted enlargement of a left axillary tumor that had been present for 20 years. The tumor was resected and the specimen, measuring 3.0 cm × 1.5 cm, revealed an encapsulated benign eccrine spiradenoma as well as an undifferentiated carcinoma possessing both carcinomatous and sarcomatous components. A transition zone was evident between the benign eccrine spiradenoma and the undifferentiated carcinoma, suggesting that the latter had arisen from the benign tumor. The malignant areas consisted principally of undifferentiated carcinoma (70%), although squamous cell carcinoma (10%), adenocarcinoma (10%), and chondrosarcomatous (10%) components were also present. Numerous mitotic figures were noted within the areas of malignant change, suggesting that the tumor was aggressive in nature. The patient died of systemic metastases 7 months after diagnosis. Conclusion. Although eccrine spiradenomas are usually benign, they can, on rare occasions, undergo malignant transformation. This case report describes one such occurrence of malignant transformation of a benign eccrine spiradenoma that unfortunately resulted in the patient's death from systemic metastases 7 months after diagnosis. [source] Reflections on Latin American Rural Studies in the Neoliberal Globalization Period: A New Rurality?DEVELOPMENT AND CHANGE, Issue 6 2008Cristóbal Kay ABSTRACT This article explores the emergence over the last decade of a new approach to rural development studies in Latin America known as the ,new rurality'. The various interpretations and ambiguities of this approach as well as the ensuing debates are discussed. Analysis focuses on four major transformations in the rural economy and society which are usually highlighted by the ,new ruralists'. These changes are interpreted as arising from the region's neoliberal shift and its closer insertion into the global system. A novel distinction is made between reformist and communitarian proposals for a new rurality. The merits as well as the limitations of this new approach to rural studies are examined. [source] Coeliac disease and Type 1 diabetes mellitus , the case for screeningDIABETIC MEDICINE, Issue 3 2001G. K. T. Holmes SUMMARY Aim To review the relationship between coeliac disease and Type 1 diabetes mellitus with emphasis on prevalence of coeliac disease, presentation and implications for screening. Methods Papers collected over many years by the author have been included in the review and a literature search employing Medline was undertaken to August 2000. Search words used were coeliac disease and diabetes mellitus. Results Twenty papers exploring the prevalence of coeliac disease by serological screening of Type 1 diabetes in children, eight in adults and two including both groups were found. An additional 48 papers are included and relate to serological screening tests for coeliac disease, expressions and complications of coeliac disease, the value of GFD and the genetics of the two conditions. Unless formal screening studies are undertaken coeliac disease will not be diagnosed because patients are asymptomatic, have atypical symptoms or even in those with symptoms the diagnosis is overlooked. Based on small bowel biopsy, diagnosis the prevalence of coeliac disease in Type 1 diabetes in children is 1:6 to 1:103 and in adults 1:16 to 1:76. Patients may improve following the start of a gluten-free diet (GFD) in terms of symptoms, growth in children, serum antibody levels, haematological and biochemical indices, morphology of the small intestinal mucosa and control of diabetes. Conclusion Coeliac disease commonly occurs in Type 1 diabetes. It is recommended that screening for coeliac disease should be part of the routine investigation and offered to all patients because of the high prevalence and the potential benefits of treatment with a GFD. This includes control of symptoms, stabilization of diabetes and prevention of complications associated with coeliac disease. The cost per patient diagnosed with coeliac disease from the existing population with Type 1 diabetes would be £860 and for those newly arising £950.
