Appendiceal endometriosis as a rare cause of abdominal pain - a case report and literature review

Endometriosis is an estrogen-dependent inflammatory disease, common in young women, characterized by the presence of endometrial tissue outside the uterine cavity. This ectopic endometrial tissue is most commonly found in the ovaries, peritoneum, uterosacral ligaments and rectovaginal cul-de-sac, with extremely rare involvement of the appendix. The main symptom is chronic abdominal pain, and the diagnosis is often made later, after the result of the histopathological examination. This study reports a 34-year-old patient complaining of chronic pelvic pain refractory to medical treatment, having undergone diagnostic laparotomy. During the surgery, we observed the presence of endometrioma fixed to the uterine wall, and the appendix was enlarged, but without evidence of inflammation. Endometrioma resection and appendectomy were performed, with good postoperative recovery. The anatomopathological exam showed endometriosis in the cecal appendix.

Intra-abdominal hypertension in horses

Intra-abdominal hypertension (IAH) may lead to a multiple organ dysfunction syndrome associated with significant dysfunction of the cardiovascular, respiratory, renal, gastrointestinal and central nervous systems of human patients. A recent prospective multicentre epidemiological investigation in man concluded that IAH was associated with an increased risk of mortality in critically ill patients. In this review, we present current information pertaining to the potential clinical importance of IAH in the context of equine clinical practice. In conclusion, consideration of intra-abdominal pressure should be a part of the clinical assessment of patient well-being in critically ill equine patients. © 2011 EVJ Ltd.

Morphologic and biomechanical changes of thoracic and abdominal aorta in a rat model of cigarette smoke exposure

Background: Smoking is the most relevant environmental factor that affects the development of aortic aneurysm. Smokers have elevated levels of elastase activity in the arterial wall, which leads to weakening of the aorta. The aim of this study was to verify whether cigarette smoke exposure itself is capable of altering the aortic wall. Methods: Forty-eight Wistar rats were divided into 2-, 4-, and 6-month experimental periods and into 2 groups: smokers (submitted to smoke exposure at a rate of 40 cigarettes/day) and nonsmokers. At the end of the experimental periods, the aortas were removed and cross-sectioned to obtain histologic specimens for light microscopic and morphometric analyses. The remaining longitudinal segments were stretched to rupture and mechanical parameters were determined. Results: A degenerative process (i.e., a reduction in elastic fibers, the loss of lamellar arrangement, and a reduction of smooth muscle cells) was observed, and this effect was proportional in intensity to the period of tobacco exposure. We observed a progressive reduction in the yield point of the thoracic aorta over time (P < 0.05). There was a decrease in stiffness (P < 0.05) and in failure load (P < 0.05) at 6 months in the abdominal aorta of rats in the smoking group. Conclusions: Chronic exposure to tobacco smoke can affect the mechanical properties of the aorta and can also provoke substantial structural changes of the arterial wall. © 2013 Elsevier Inc.

Implantação de biomembrana de colágeno tratada em solução alcalina ou conservada em glicerina a 98% na parede abdominal de equinos

The objective of this research was obtain collagen biomembranes treated in alkaline solution for 72 hours (GE) from tendineous diaphragmatic center of equines and compare its biocompatibility with membranes preserved in a glycerin solution 98% (GG) and membranes do not treated (GC). The membranes were implanted in the internal fascia of recto abdominis muscle of equines and removed, with adjacent tissues, seven, 63 and 126 days postoperative for the preparation of histological slides. The histomorphometric study revealed more intense inflammatory process to GG and CC implants and faster healing for GE implants. It was concluded that the collagen biomembranes treated in alkaline solution is more biocompatible than biomembranes preserved in 98% glycerin.

Intra-abdominal fat is related to metabolic syndrome and non-alcoholic fat liver disease in obese youth

Background: Previous studies have shown an association between adiposity, especially intra-abdominal adipose tissue, and hemodynamic/metabolic comorbidities in adults, however it is not clear in pediatric population. The aim of the study was to analyze the relationship between non-alcoholic fatty liver disease (NAFLD) and components of metabolic syndrome (MS) with values of intra-abdominal (IAAT) and subcutaneous (SCAT) adipose tissue in obese children and adolescents.Methods: Cross-sectional study. Subjects: 182 obese sedentary children and adolescents (aged 6 to 16 y), identified by the body mass index (BMI). Measurements: Body composition and trunk fat by dual-energy X-ray absorptiometry- DXA; lipid profile, blood pressure and pubertal stage were also assessed. NAFLD was classified as absent (0), mild (1), moderate (2) and severe (3), and intra-abdominal and subcutaneous abdominal fat thickness were identified by ultrasound. The MS was identified according to the cut offs proposed by World Health Organization adapted for children and adolescents. The chi-square test was used to compare categorical variables, and the binary logistic regression indicated the magnitude of the associations adjusted by potential cofounders (sex, age, maturation, NAFLD and HOMA-IR).Results: Higher quartile of SCAT was associated with elevated blood pressure (p = 0.015), but not associated with NAFLD (p = 0.665). Higher IAAT was positively associated with increased dyslipidemia (p = 0.001), MS (p = 0.013) and NAFLD (p = 0.005). Intermediate (p = 0.007) and highest (p = 0.001) quartile of IAAT were also associated with dyslipidemia, independently of age, sex, maturation, NAFLD and HOMA-IR (homeostatic model assessment-insulin resistance).Conclusion: Obese children and adolescents, with higher IAAT are more prone to develop MS and NAFLD than those with higher values of SCAT, independent of possible confounding variables. © 2013 Silveira et al.; licensee BioMed Central Ltd.

Energy and fat intake are not associated with abdominal adiposity

Background and objective: Central or abdominal obesity (AA) is a highly prevalent determinant of the metabolic syndrome and its control requires intervention strategies. This study investigated the risk factors associated with the presence of AA in hospitalized individuals. Patients and methods: A total of 1626patients were studied. The investigated risk factors possibly associated with AA were gender, age, body mass index (BMI), habitual energy intake (HEI) and fat intake (FI). AA was determined by waist circumference (WC) and waist-to-hip ratio (WHR). The chi2, Mann-Whitney and Kruskal-Wallis tests were used to compare the data and univariate and multiple logistic regressions were used to identify the predictive factors of AA. Results: Women were at higher risk of developing AA than men (P. <. 0.0001). The HEI and FI of individuals with and without AA and of women and men were not significantly different. According to multivariate analysis, HEI was not a predictive factor of AA, contrary to gender and age. The risk factors for AA, determined by WC, were gender (OR. = 6.8; CI. = 5.3-8.7) and age (OR. = 1.0; CI. = 1.0-1.0). Women were six times more likely to develop AA than men. Conclusions: Evidence of an association between AA and HEI or FI was not found, but gender and age were associated with AA. © 2013 Elsevier Masson SAS.

Correction of rectal sacculation through lateral resection in dogs with perineal hernia ? Technique description

The occurrence of perineal hernias in dogs during routine clinical surgery is frequent. The coexistence of rectal diseases that go undiagnosed or are not correctly treated can cause recurrence and postoperative complications. The objective of this report is to describe a surgical technique for treatment of rectal sacculation through lateral resection in dogs with perineal hernia, whereby restoring the rectal integrity.
