Silva, José O. de Almeida;Carvalho-Filho, Fernando da S.;Esposito, Maria C.;Reis, Geniana A.;
Revista Brasileira de Entomologia , 2012, DOI: 10.1590/S0085-56262012000100019
Abstract: first record of chrysomya rufifacies (macquart) (diptera, calliphoridae) from brazil. in addition to its native fauna, the neotropical region is known to be inhabited by four introduced species of blow flies of the genus chrysomya. up until now, only three of these species have been recorded in brazil - chrysomya albiceps (wiedemann), chrysomya megacephala (fabricius), and chrysomya putoria (wiedemann). in south america, c. rufifacies (macquart) has only been reported from argentina and colombia. this study records c. rufifacies from brazil for the first time. the specimens were collected in an area of cerrado (savanna-like vegetation) in the municipality of caxias in state of maranh?o, and were attracted by pig carcasses.

Abstract: the objective of this study is to evaluate the effect of the daily consumption of ostrich meat (lliofemuralis internus) and bovine meat (psoas major) on the lipid metabolism in adult mice. the analyses of the centesimal composition of the meats and preparation of the diets were accomplished following the recommendations of the american institute of nutrition-ain-93. three groups of 150 day-old animals: group i (diet i, with casein), group ii (diet ii, with ostrich meat), and group iii (diet iii with bovine meat) were fed for 13 weeks with the respective diets and weight gain, food efficiency coefficient, total cholesterol, lipoprotein fractions, hepatic, transaminases and body fat percentage and hepatic fat content were evaluated. no difference (p < 0.05) it was found for weight gain and coefficients for feed efficiency among the groups. total cholesterol, hdl-cholesterol, ldl-cholesterol, relationship of total cholesterol/hdl-cholesterol, vldl, triglycerides and hepatic transaminases were also not different among the groups (p < 0.05). this research suggests that the consumption of ostrich meat or thin bovine meat on a daily basis does not raise concerns about weight gain, and an increase in the plasma concentrations of lipoprotein and levels of hepatic transaminase.

Abstract: We report the case of a 22-year-old man in whom disseminated infection with paracoccidioidomycosis was associated with hypercalcemia. The patient had a high normal serum level of 1,25-dihydroxyvitamin D and a suppressed parathyroid hormone value, an indication that the hypercalcemia was not mediated by parathyroid hormone and might be associated with 1,25-dihydroxyvitamin D.The episode resolved readily with administration of corticosteroids, an outcome suggesting that this is an effective treatment of hypercalcemia of this origin. On follow-up, while receiving antifungal therapy for P. brasiliensis the patient's calcium values remained normal.Hypercalcemia is well described in various granulomatous disorders, such as sarcoidosis, tuberculosis, berylliosis, leprosy and fungal infections. Among the fungal diseases, disseminated candidiasis, histoplasmosis, cryptococcosis and coccidioidomycosis have rarely been implicated as causes of hypercalcemia [1-5]. In this report we describe a patient in whom hypercalcemia was associated with disseminated infection with Paracoccidioides brasiliensis and a high normal serum level of 1,25-dihydroxyvitamin D.The patient, a 22-year-old male agriculturalist was admitted to our hospital in November 2006 with asthenia, weight loss, fever, diffuse enlargement of cervical lymph nodes and enlarged liver and spleen. The patient's temperature was 38.5°C and his blood pressure was 120/80 mmHg with a pulse of 96 beats per minute.Initial laboratory studies included an erythrocyte sedimentation rate of 89 mm/hour, serum hemoglobin of 11.4 g/dl, white blood cell count of 13,690/mm3 (27% eosinophils), serum albumin of 2.4 g/dl, normal serum urea, creatinine, sodium and potassium. On admission, the patient had a total serum calcium level of 10.4 mg/dl (normal range 8.4 to 9.7 mg/dl; ~12 mg/dl when corrected for albumin), ionized calcium of 1.46 mmol/l (normal range 1.15 to 1.29 mmol/l) and phosphorus of 4.9 mg/dl (normal range 2.7 to 4.5 mg/dl).

Abstract: insulin (ins) and angiotensin ii (aii) play pivotal roles in the control of two vital and closely related systems: the metabolic and the circulatory, respectively. a failure in the proper action of each of these hormones results, to a variable degree, in the development of two highly prevalent and commonly overlapping diseases - diabetes mellitus (dm) and hypertension (ah). in recent years, a series of studies has revealed a tight connection between the signal transduction pathways that mediate ins and aii actions in target tissues. this molecular cross-talk occurs at multiple levels and plays an important role in phenomena that range from the action of anti-hypertensive drugs to cardiac hypertrophy and energy acquisition by the heart. at the extracellular level, the angiotensin-converting enzyme controls aii synthesis but also interferes with ins signaling through the proper regulation of aii and the accumulation of bradykinin. at an early intracellular level, aii, acting through jak-2/irs-1/pi3-kinase, jnk and erk, may induce the serine phosphorylation and inhibition of key elements of the ins-signaling pathway. finally, by inducing the expression of the regulatory protein socs-3, aii may impose a late control on the ins signal. this review will focus on the main advances obtained in this field and will discuss the implications of this molecular cross-talk in the common clinical association between dm and ah.

Abstract: The aim of this study was to evaluate the effect of chronic treatment with diets rich in carbohydrates on the IgM and IgG antibody production and the seric glucose concentration in diabetes. Nonobese diabetic (NOD) mice received, ad libitum, by oral route, the diet consisting of an aqueous extract (20 mg/mL) of the following flours: babassu mesocarp, manioc, corn or rice, during 120 days. The diet intake was monitored throughout this period. At the end, the weight variation, blood glucose, serum IgG and IgM antibody and IgM anti-insulin titers, were determined. The babassu and manioc flour extracts altered Purina chow intake and these animals also presented a significant increase in body weight. In contrast, treatment with rice flour resulted in a significant weight loss. Moderate to severe hyperglycemia was observed in the groups receiving rice and manioc, whereas treatment with babassu mesocarp flour and cornmeal resulted in hypoglycemia. The extracts did not alter the IgG concentration. On the other hand, the cornmeal extract caused a marked reduction in both total IgM and anti-insulin IgM antibody production. Although babassu mesocarp flour, cornmeal and manioc flour caused important variations in the parameters studied, only treatment with the rice flour extract anticipated the onset of diabetes in male mice genetically predisposed to the disease.

Abstract: context and objective: the main causes of hepatic steatosis (hs) are alcoholic liver disease and nonalcoholic fatty liver disease (nafld). although liver biopsy is the gold standard for nafld diagnosis, the finding of abnormal aminotransferases in abstinent individuals, without known liver disease, suggests the diagnosis of nafld in 80-90% of the cases. identification of clinical factors associated with hs on abdominal ultrasound may enable diagnoses of fatty liver non-invasively and cost-effectively. the aim here was to identify clinical variables associated with hs in individuals with elevated alanine aminotransferase (alt) levels. design and setting: cross-sectional study in a single tertiary care center. methods: individuals with elevated alt, serologically negative for hepatitis b and c, were evaluated by reviewing medical files. patients who did not undergo abdominal ultrasonography were excluded. results: among 94 individuals included, 40% presented hs on ultrasonography. compared with individuals without hs, those with fatty liver were older (p = 0.043), with higher body mass index (bmi) (p = 0.003), diabetes prevalence (p = 0.024), fasting glucose levels (p = 0.001) and triglycerides (p = 0.003). multivariate analysis showed that bmi (odds ratio, or = 1.186; 95% confidence interval, ci: 1.049-1.341; p = 0.006) and diabetes mellitus (or = 12.721; 95% ci: 1.380-117.247; p = 0.025) were independently associated with hs. conclusions: simple clinical findings such as history of diabetes and high bmi may predict the presence of hs on ultrasonography in individuals with elevated alt and negative serological tests for hepatitis.

Abstract: introduction: although various studies have been published regarding the treatment of chronic hepatitis c (chc) with peginterferon (peg-ifn) and ribavirin, little is known regarding the real impact of gender on the characteristics that influence the effectiveness and safety of antiviral treatment for chc patients. the objective of this study was to evaluate the influence of gender on hcv treatment outcomes. methods: a retrospective analytical study was conducted among selected carriers of chc genotype 1, who were treated with peg-ifn α-2b at a dose of 1.5 μg/kg or peg-ifn α-2a at a dose of 180 μg/week plus a ribavirin dose of 1,000-1,250 mg/day, according to weight, between 2001 and 2007. results: among 181 patients undergoing treatment, the mean age was 46.4 ± 11.0 years and 46% were women. at baseline, 32% of the patients had advanced fibrosis (f3-f4 scheuer), and 83% of the subjects had viral load > 400,000 iu/ml, without significant difference between the genders (p = 0.428 and p = 0.452, respectively). when compared with men, women had higher incidence of many adverse events such as anemia (p < 0.001) and higher need for dose reduction, for both peg-ifn (p = 0.004) and ribavirin (p = 0.006). however, the rate of sustained virological response (svr) did not differ between the genders: 45% (female) vs 41% (male); p=0.464. conclusions: this study suggests that women and men react differently to combined therapy, especially in relation to the incidence of adverse events and the need for dose modification. nevertheless, these differences do not influence the svr rate.
