Teníase: Uma causa rara de apendicite aguda

Acute appendicitis is the most common surgical condition of acute abdomen. Approximately 7 percent of the population will have appendicitis during their lifetime, with the peak incidence occurring between 10 through 30 years-old Obstruction of the appendix lumen with subsequent bacterial infection initiates the pathophysiological sequence of acute appendicitis. Obstruction may have multiple causes, including fecalith, lymphoid hyperplasia (related to viral illnesses, including upper respiratory infection, mononucleosis, and gastroenteritis), foreign bodies, carcinoid tumor and parasites. In Asia, Africa and Latin America, Enterobius vermicularis has been reported as the main parasite that causes appendix obstruction. Rarely, Taenia sp., has been pointed as a cause of parasitic appendicitis. We reported a 30 years-old patient clinically diagnosed with acute appendicitis. The appendectomy was performed through a McBurney incision. The patient's convalescence was uneventful, and he was discharged from hospital 48 hours after operation. Histological examination of the appendix showed acute appendicitis, and it was found aparasite (Taenia sp.) lying inside of the appendix lumen at a transverse section. He has received 10 mg/Kg weight of praziquantel for taeniasis treatment.

Toxicidade aguda do sulfato de cobre e do extrato aquoso de folhas secas de nim para o caramujo (Pomacea canaliculata)

Snails can become an environmental and economic problem, causing substantial losses. The objective of this work was to estimate the acute toxicity of copper sulfate pentahydrate (CuSO4.5H2O) and the aqueous extract of dried neem leaves on snails (P. canaliculata) under laboratory conditions. In order to estimate the lethal concentration 50% (LC (I)50;96h), snails were exposed to six increasing copper sulfate concentrations (0.0; 0.01; 0.03; 0.05; 0.07 and 0.1 mg L-1) and six increasing concentrations of aqueous extract of dried neem leaves 0.0; 100; 125; 150; 175 and 200 mL aqueous extract of dried neem leaves L-1 water, equivalent to (0.0; 1.18; 1.47; 1.77; 2.06 and 2.36 mg azadirachtin L -1), in triplicate and one control treatment in an entirely random delineation. Estimated LC (I)50;96h, of copper sulfate was 0.02 mg copper sulfate L-1, with a 0.01 mg L-1 lower limit and a 0.03 mg L-1 upper limit. Estimated lethal concentration 50% of the aqueous extract of dried neem leaves was 142.75 mL L-1, equivalent to 1.68 mg L-1 of azadirachtine, with a 130.89 mL L-1 (1.54 mg L-1) low limit and 155.69 mL L-1 (1.83 mg L -1) as the upper limit.

Perfil eletroforético das proteínas de fase aguda em caprinos experimentalmente infectados com Trypanosoma evansi

Considered as one of the main agents of the tripanossomiases, Trypanosoma evansi causes a disease generically know as surra, with wide geographic occurence. This work has the aim to study the electrophoretic profile of the acute phase proteins of goats, experimentally infected with T. evansi. Ten crossbread female goats, around 4 months of age, clinically healthy and serum negative for the presence of antibodies anti-T. evansi (IFAT) were used. The animals were divided in two groups: six were inoculated (G1) intravenously with 2,38 × 10 6 tripomastigotes of T. evansi and four were kept as noninfected controls. The blood for serum was collected daily until the 14 days after inoculation (DAI), weekly up to the 98 th DAI and every two weeks up to the 364 th DAI. The serum proteins were separacted by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDSPAGE). Twenty-one proteins were found in the serum of the goats, eight were nominally identified; phosphorylase, transferrin, albumin, antitrypsin, acid glicoprotein, haptoglobin, hemoglobin, and light chain immunoglobulin.

Fondaparinux em intervenção coronária percutânea no tratamento da síndrome coronária aguda

Background: Fondaparinux is considered an agent with a well-established safety and efficacy profile in the treatment of non-ST segment elevation acute coronary syndromes, but when used alone, is associated to a higher incidence of thrombotic complications during invasive coronary procedures, requiring the supplementation of an anti-IIa agent. This study aimed to evaluate the efficacy and safety of percutaneous coronary intervention (PCI) in patients with non-ST segment elevation acute coronary syndromes previously treated with fondaparinux. Methods: Prospective, controlled registry enrolling 127 consecutive patients submitted to an early invasive stratification during treatment with fondaparinux, with supplementation of intravenous unfractionated heparin at a dose of 85 U/kg at the time of PCI. Results: The rate of the composite primary endpoint including death, acute myocardial infarction, stroke, stent thrombosis or emergency myocardial revascularization was 3.2%. The cumulative incidence of major bleeding and vascular complications was 3.2%. There were no cases of guidecatheter thrombosis or abrupt vessel closure. Conclusions: PCI in patients with acute coronary syndromes receiving fondaparinux is associated with a low rate of major adverse cardiovascular ischemic events and severe hemorrhagic complications. Supplementation of unfractionated heparin during the invasive procedures eliminates the risk of catheter-related thrombosis.

Aerocistite aguda induzida por tioglicolato, lipolisacarídeo e Aeromona hydrophila inativada em Piaractus mesopotamicus: Efeitos hematológicos

The effects of swim bladder injection with thioglycolate, Escherichia coli lipopolysaccharide (LPS) and heat-inactivated Aeromonas hydrophila were assessed on hematological responses in pacu, Piaractus mesopotamicus (Characidae). A quantitative assessment was done on erythrocytes, thrombocytes e leucocytes at 6, 24, and 48 h pos-injection of the inflammatory agents and compared with fish injected with saline solution (control). Fish injected with inactivated A. hydrophila showed a reduction of erythrocytes and hemoglobin, whereas the hematocrit increased 6 h pos-injection. The results show that thioglycolate and LPS also induced a reduction on hemoglobin and an increase on the hematocrit. The thrombocytes count decreased 6 h post A. hydrophila injection, whereas increased 48 hours post LPS injection. The leukocytes count increased after 6 h post A. hydrophila injection, while the lymphocytes and PAS-positive granular leukocytes (PAS-LG) count decreased after 24 h post injection. In fish injected with thioglycolate or with LPS showed an increase in the LG-PAS counts when compared to A. hydrophila or control groups. The monocytes count was not affected by the different inflammatory agents.
