Tako-Tsubo Cardiomyopathy—The Role of Physical and Emotional Stressors: Two Case Report  [PDF]
Patrícia Margarida Serra Carvalho, Jandira Helena Lima, Joo Bernardo Cunha, Patrícia Glória Dinis Dias, José Gon?alo Diniz Vieira, José Manuel Nascimento Costa
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.32029
Abstract: Introduction: Tako-Tsubo cardiomyopathy describes a form of acute and reversible left ventricular dysfunction with a clinical presentation, ECG and cardiac biomarkers that makes it indistinguishable from acute coronary syndrome. Case Presentation: The authors present two cases of tako-tsubo cardiomyopathy in postmenopausal women, the first case following an emotional stressful event and a second case following a blood transfusion and probably associated with intravenous catecholamine perfusion. Both had unobstructed coronary arteries and regional wall-motion abnormalities typical of this syndrome. Conclusions: Tako-tsubo cardiomyopathy is a condition often misdiagnosed. A clinical presentation suggestive of acute coronary syndrome in a postmenopausal woman without history of coronary disease and in whom a precipitating stressful event can be found should lead the physician to suspect the diagnosis of tako-tsubo cardiomyopathy. This syndrome associated with blood transfusion has rarely been described.

Abstract: objective: occupational exposure typical of an oil refinery may alter liver function among the workers. thus, the objective of the study was to identify risk factors for liver enzyme abnormalities among oil refinery workers. methods: the workers at an oil refinery in northeastern brazil underwent routine annual medical examination from 1982 to 1998. this case-control study investigated all the 150 cases of individuals with simultaneous gamma-glutamyltransferase and alanine aminotransferase abnormalities of at least 10% above reference levels. as controls, 150 workers without any liver enzyme or bilirubin abnormalities since starting to work there were selected. odds ratios and the respective 95% confidence intervals were calculated from logistic regression models. results: in all the production sectors, the risk of liver enzyme abnormalities was significantly higher than in the administrative sector (or=5.7; 95% ci: 1.7-18.4), even when the effects of alcohol, obesity and medical history of hepatitis were controlled for. during the period from 1992 to 1994, 88 out of the 89 cases occurred among workers from the various production sectors. conclusions: occupational exposure plays an important role in causing liver enzyme abnormalities among oil refinery workers. this is in addition to the specifically biological and/or behavioral risk factors such as obesity and alcohol consumption.

Abstract: purpose: to evaluate the biodistribution of sodium pertecnetate (na99mtco4) in organs and tissues, the morphometry of remnant intestinal mucosa and ponderal evolution in rats subjected to massive resection of the small intestine. methods: twenty-one wistar rats were randomly divided into three groups of 7 animals each. the short bowel (sb) group was subjected to massive resection of the small intestine; the control group (c) rats were not operated on, and soft intestinal handling was performed in sham rats. the animals were weighed weekly. on the 30th postoperative day, 0.l ml of na99mtco4, with mean activity of 0.66 mbq was injected intravenously into the orbital plexus. after 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. the biopsies were washed with 0.9% nacl.,the radioactivity was counted using gama counter wizardtm 1470, perkinelmer. the percentage of radioactivity per gram of tissue (%ati/g) was calculated. biopsies of the remaining jejunum were analysed by he staining to obtain mucosal thickness. analysis of variance (anova) and the tukey test for multiple comparisons were used, considering p<0.05 as significant. results: there were no significant differences in %ati/g of the na99mtco4 in the organs of the groups studied (p>0.05). an increase in the weight of the sb rats was observed after the second postoperative week. the jejunal mucosal thickness of the sb rats was significantly greater than that of c and sham rats (p<0.05). conclusion: in rats with experimentally-produced short bowel syndrome, an adaptive response by the intestinal mucosa reduced weight loss. the biodistribution of na99mtco4 was not affected by massive intestinal resection, suggesting that short bowel syndrome is not the cause of misleading interpretation, if an examination using this radiopharmaceutical is indi

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2013, DOI: 10.4236/ijohns.2013.25036
Abstract: Objectives: The biologic behavior of the adenoid cystic carcinoma (ACC) and the factors predicting outcome for these tumors are still poorly understood. Our objective is to analyze the predicting factors and the value of different treatment possibilities, since none sole treatment has been standardized. Methods: A retrospective analysis of the epidemiologic, clinical and histologic aspects of ACC, as well as treatment options and other prognostic factors of all the cases of ACC of the head and neck treated at this Institution were analyzed. From 1974 until 2011, 152 patients were diagnosed with ACC and treated at the Portuguese Institute of Oncology (Porto Centre). Main outcome measures: overall survival, local recurrence and distant metastasis were calculated by the Kaplan-Meier method. Factors predictive of outcome were identified by univariate and multivariate analysis. Results: The mean age at diagnosis was 55.8 years (range, 19-83 years). Incidence was higher in the female population, with a female to male ratio of 1.7:1 respectively. The primary tumor location was hard palate and submandibular region in 56 cases, 28 in each location (24.6%), parotid gland (17 cases, 14.9%) and oral cavity excluding palate (16 cases, 14%).Distributions according to T stage were: T1 (29.8%); T2 (30.7%); T3 (17.5%); T4 (22%). The overall 1-year, 5-year and 10-year survival for all patients were 94.6%, 60.5%, 41.6%, respectively. Conclusions: Univariate survival analysis revealed that age older than 60 years (p = 0.002), solid histologic subtype (p = 0.042), advanced clinical stage (p < 0.001) and the presence of perineural invasion (p = 0.036) were correlated with a poor survival. Multivariate analysis confirmed that age and advanced clinical

Case Reports in Clinical Medicine (CRCM) , 2016, DOI: 10.4236/crcm.2016.53018
Abstract: A 62 years old, post-menopausal female was admitted to the Internal Medicine Ward due to dyspnoea, cough and sputum of at least 2 months. Shortness of breath, cough and hypoxaemia persisted and the patient was submitted to a pulmonary angiogram ct which revealed numerous thin-walled air cysts affecting upper and medial zones of both lungs, typical images of pulmonary lymphangioleiomyomatosis. After discharge to Internal Medicine Consultation Service with Metilprednisolone, the patient was no longer hypoxaemic and remained asymptomatic, even after withdrawal of oral corticosteroid to inhalatory formulation. Further surveillance in short time was scheduled in order to implement rapid imunossupressive treatment when necessary.
