Giant benign lymphangioendothelioma with positive expression of Wilms tumor 1: A case report

Benign lymphangioendothelioma (BL, acquired progressive lymphangioma) is a rare, slow-growing lymphatic tumor, first described 40 years ago, with fewer than 50 published cases. Clinically, it presents as a skin-colored or erythematous patch. Definitive diagnosis requires histopathological examination. The immunohistochemical staining profile is still controversial regarding Wilms tumor 1 (WT1) expression, a marker of proliferative and neoplastic, rather than malformative nature. Here, we report a case of a 60-cm-long BL on the breast of an adult female. Biopsy revealed irregular vascular spaces dissecting the collagen bundles lined by swollen endothelial cells but without cellular atypia. Positivity for podoplanin (D2-40), CD31, and WT1 was observed, supporting the neoplastic nature of this lesion. Dermatologists and pathologists must be aware of this entity for early diagnosis and treatment.     

Dietary program and physical activity impact on biochemical markers in patients with type 2 diabetes: A systematic review

Objectives

Evaluate the effectiveness of the implementation of independently or combined dietary and physical activity programs on the blood glucose values and lipid profile in patients with type 2 diabetes, including participants aged 60 years and over.

Ex Vivo Detection of Apical Delta in Premolars: A Comparative Study Using Periapical Radiography,Cone-beam Computed Tomography,and Micro–computed Tomography

Introduction

Imaging methods are essential for the correct identification of root canal anatomy, which is a key factor for successful endodontic therapy. This study aimed to evaluate the performance of periapical radiography (PR) and cone-beam computed tomographic (CBCT) imaging in identifying the apical delta (AD) using micro-computed tomographic imaging as the gold standard.

Quality of Actions to Control Cervical Cancer in Bahia,Brazil

Objective: To assess the quality of the actions to control cervical cancer (CC) and its correlates. Methods: This is a cross-sectional study conducted from January to March 2019 in 19 municipalities in Bahia, Brazil, with a sample of 241 doctors and nurses from primary health care (PHC). Three dependent variables were chosen- “Performance of educational, promotion, prevention, and monitoring actions” (D1); “Access to diagnostic tests” (D2); “Non-occurrence of high grade cervical squamous intraepithelial lesions (HSIL)” (D3). Poisson regression with robust variance was used, adopting hierarchical input variables to estimate the prevalence ratios and confidence intervals of 95%. Results: The following prevalence rates were found: D1  39.8% (95% CI: 33.8-46.2); D2  73.9% (95% CI: 67.9-79.1); and D3  46.4% (95% CI: 39.9-53.0). These dimensions remained associated with the dependent variables: D1- having professional training courses on the topic; consideration to ensure that collection takes place appropriately by a professional; and women having access to medical transport; D2- nurses treating low-grade lesions; D3- recording the Papanicolaou in electronic medical records; D1 and D2- professionals joining the service through public tender; D1 and D3- working in the PHC (≥ 2 years); D2 and D3- recording Papanicolaou in physical records; and performance of Papanicolaou by residents. Conclusion: Better trained professionals and professionals working in stable work arrangements are associated with comprehensive actions to control CC. Such strategies indicate that investments in work management result in a more organized PHC and more solution-centered work processes. Therefore, working in the PHC for a longer time and nurses performing more clinical actions (collection and treatment) are favored by such organizational actions. Investments in diagnostic support contribute to perceptions of more comprehensive actions to control CC.     

Aluminium oxide nanoparticles induced morphological changes,cytotoxicity and oxidative stress in Chinook salmon (CHSE‐214) cells

Aluminium oxide nanoparticles (Al₂O₃ NPs) are increasingly used in diverse applications that has raised concern about their safety. Recent studies suggested that Al₂O₃ NPs induced oxidative stress may be the cause of toxicity in algae, Ceriodaphnia dubia, Caenorhabditis elegans and Danio rerio. However, there is paucity on the toxicity of Al₂O₃ NPs on fish cell lines. The current study was aimed to investigate Al₂O₃ NPs induced cytotoxicity, oxidative stress and morphological abnormality of Chinnok salmon cells (CHSE‐214). A dose‐dependent decline in cell viability was observed in CHSE‐214 cells exposed to Al₂O₃ NPs. Oxidative stress induced by Al₂O₃ NPs in CHSE‐214 cells has resulted in the significant reduction of superoxide dismutase, catalase and glutathione in a dose‐dependent manner. However, a significant increase in glutathione sulfo‐transferase and lipid peroxidation was observed in CHSE‐214 cells exposed to Al₂O₃ NPs in a dose‐dependent manner. Significant morphological changes in CHSE‐214 cells were observed when exposed to Al₂O₃ NPs at 6, 12 and 24 h. The cells started to detach and appear spherical at 6 h followed by loss of cellular contents resulting in the shrinking of the cells. At 24 h, the cells started to disintegrate and resulted in cell death. Our data demonstrate that Al₂O₃ NPs induce cytotoxicity and oxidative stress in a dose‐dependent manner in CHSE‐214 cells. Thus, our current work may serve as a base‐line study for future evaluation of toxicity studies using CHSE‐214 cells. Copyright © 2015 John Wiley & Sons, Ltd.     

Evaluation of selective attention in patients with misophonia

IntroductionMisophonia is characterized by the aversion to very selective sounds, which evoke a strong emotional reaction. It has been inferred that misophonia, as well as tinnitus, is associated with hyperconnectivity between auditory and limbic systems. Individuals with bothersome tinnitus may have selective attention impairment, but it has not been demonstrated in case of misophonia yet.ObjectiveTo characterize a sample of misophonic subjects and compare it with two control groups, one with tinnitus individuals (without misophonia) and the other with asymptomatic individuals (without misophonia and without tinnitus), regarding the selective attention.MethodsWe evaluated 40 normal-hearing participants: 10 with misophonia, 10 with tinnitus (without misophonia) and 20 without tinnitus and without misophonia. In order to evaluate the selective attention, the dichotic sentence identification test was applied in three situations: firstly, the Brazilian Portuguese test was applied. Then, the same test was applied, combined with two competitive sounds: chewing sound (representing a sound that commonly triggers misophonia), and white noise (representing a common type of tinnitus which causes discomfort to patients).ResultsThe dichotic sentence identification test with chewing sound, showed that the average of correct responses differed between misophonia and without tinnitus and without misophonia (p = 0.027) and between misophonia and tinnitus (without misophonia) (p = 0.002), in both cases lower in misophonia. Both, the dichotic sentence identification test alone, and with white noise, failed to show differences in the average of correct responses among the three groups (p ≥ 0.452).ConclusionThe misophonia participants presented a lower percentage of correct responses in the dichotic sentence identification test with chewing sound; suggesting that individuals with misophonia may have selective attention impairment when they are exposed to sounds that trigger this condition.
