Influencia da obesidade na correlacao entre refluxo faringolaringeo e apneia obstrutiva do sono

Introdução:A apneia obstrutiva do sono (AOS) é causada por episódios recorrentes de obstrução total ou parcial da via aérea superior com duração superior a 10 segundos durante o sono. Refluxo faringolaríngeo (RFL) é uma variante da doença do refluxo gastroesofágico que afeta a laringe e a faringe.Objetivos:Avaliar a influência da obesidade na relação entre RFL e AOS em pacientes com SAOS.Materiais e métodos:Estudo observacional transversal retrospectivo. Foram revisados protocolos de atendimento de pacientes com AOS que incluem questionários validados para RFL como Reflux Sympton Index (RSI) e Reflux Finding Score (RSI), nasolaringofibroscopia e polissonografia.Resultados:Cento e cinco pacientes foram divididos em grupo de obesos (39 pacientes) e não obesos (66 pacientes). Na avaliação das médias do RSI o grupo de não obesos foi semelhante entre pacientes com AOS leve (11,96) e moderada (11,43). No grupo de obesos a média do RSI foi de 6,7 em pacientes com AOS leve e de 11,53 em pacientes com AOS moderada a grave (p < 0,05).Discussão:O subgrupo de pacientes com AOS e RFL apresenta vários fatores que promovem a inflamação da via aérea superior. Pacientes com AOS devem ser pesquisados e tratados quanto a RFL, aumentando a qualidade de vida.Conclusão:O RFL e a AOS se correlacionam positivamente em pacientes obesos.

Proteinograma sérico e do líquido peritoneal de equinos hígidos e daqueles submetidos à obstrução intestinal experimental

Avaliou-se a resposta de fase aguda através da concentração das proteínas de fase aguda (PFA) no soro sanguíneo e no líquido peritoneal de vinte e um equinos, hígidos e submetidos à obstrução intestinal experimental, distribuídos em quatro grupos: obstrução de duodeno - GD (n=6), íleo - GI (n=6), cólon dorsal esquerdo - GM (n=6) e controle instrumentado - GC (n=3). Foram colhidas amostras de sangue e líquido peritoneal e, após centrifugação e fracionamento, as proteínas de fase aguda foram separadas por eletroforese em SDS-PAGE. Identificaram-se as proteínas IgA, ceruloplasmina, transferrina, albumina, IgG, haptoglobina, α1-glicoproteína ácida e P24, no soro e no líquido peritoneal. Houve aumento nas concentrações sérica e peritoneal de todas as PFA, sendo mais evidente no líquido peritoneal e nos animais obstruídos. O fracionamento eletroforético das PFA no líquido peritoneal é mais eficaz no diagnóstico de processos inflamatórios abdominais, quando comparado ao sérico.

Dog with hydronephrosis due to abdominal trauma

Hydronephrosis is a condition that results from complete or partial obstruction of the urinary flow. This paper reports the case of a two-year-old, mixed-breed dog diagnosed with hydronephrosis of the left kidney six months after being kicked in the thoraco-abdominal region. The diagnosis was based on radiographic and ultrasonographic examinations. Percutaneous antegrade pyelography was also performed and allowed the visualization of opacification of the left kidney, which confirmed the diagnosis. Because the exams indicated that the patient had normal renal function, nephrectomy was performed. The patient remained in good health during the postoperative period and in subsequent evaluations.

Proposta de um protocolo de terapia celular para o tratamento da doença pulmonar obstrutiva crônica

The main feature of pulmonary emphysema is airflow obstruction resulting from the destruction of the alveolar walls distal to the terminal bronchioles. Existing clinical approaches have improved and extended the quality of life of emphysema patients. However, no treatment currently exists that can change the disease course and cure the patient. The different therapeutic approaches that are available aim to increase survival and/or enhance the quality of life of emphysema patients. In this context, cell therapy is a promising therapeutic approach with great potential for degenerative pulmonary diseases. In this protocol proposition, all patients will be submitted to laboratory tests, such as evaluation of heart and lung function and routine examinations. Stem cells will be harvested by means of 10 punctures on each anterior iliac crest, collecting a total volume of 200 mL bone marrow. After preparation, separation, counting and labeling (optional) of the mononuclear cells, the patients will receive an intravenous infusion from the pool of Bone Marrow Mononuclear Cells (BMMC). This article proposes a rational and safe clinical cellular therapy protocol which has the potential for developing new projects and can serve as a methodological reference for formulating clinical application protocols related to the use of cellular therapy in COPD. This study protocol was submitted and approved by the Brazilian National Committee of Ethics in Research (CONEP - Brazil) registration number 14764. It is also registered in ClinicalTrials.gov (NCT01110252). (c) 2013 Sociedade Portuguesa de Pneumologia. Published by Elsevier Espana, S.L. All rights reserved.

Associação do treinamento resistido e aeróbico em pacientes com doença pulmonar crônica

Introduction: The pulmonary rehabilitation (PR) is composed of aerobic and resisted exercises that improve the functional capacity to the exercise, life quality and decrease respiratory symptoms in subjects with chronic pulmonary disease. Objective: Assess the effects of a combined PR program in the cardiorespiratory function and peripheral muscle strength in subjects with chronic pulmonary disease. Method: Patients with chronic pulmonary disease were submitted to the PR program, which was developed on 24 sessions of 60 minutes (three times per week). The program was composed of aerobic exercises (two times per week) and resisted exercises (once a week). Before and after the PR the patients were submitted to manovacuometry in order to measure the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP), ventilometry, peek expiratory flow (PEF), six minute walking test (6MWT) and one maximum repetition (1RM). The data are presented in absolute frequency, percentage and mean±standard deviation. The t Student test was used to compare data before and after the PR and the ANOVA test to compare before, after and predicted distances in the 6MWT (p<0.05). Results: Seven patients were part of this study, 85.70% of women, 71.40% with pulmonary emphysema diagnosis. The mean age was 69.43±5.59 years old, the height was 1.61±0.07 m, the mean weight was 66.20±8.40 kg and the body mass index mean was 25.50±2.48 kg/m². From the variables assessed, the MEP increased from 79.71±13.69 to 84.42±12.83 cmH2O (p=0,03), the PEF increase from 255.71±66.3 to 320.00±93.63 l/min (p=0,03) and the distance in the 6MWT from 415.28±47.90 to 483,79±79,77 m (p=0,02). The load in the 1RM test in the reverse peck deck exercise (before - - 17.10±8.10kg; after – 210.40±9.00kg), knee in leg extension machine (before – 17.10±9.50kg; after – 26.40±13.10kg) and hip extensors (right before – 48.60±22.10kg; after – 62.90±19.30kg; and left before – 46.40±20.10kg; after – 62.10±18.20kg) increased significantly (p<0,05). Conclusion: After the PR program there was improvement in the expiratory muscular strength, in the lower limbs strength and in the functional capacity. Besides that, there was a reduction in the airflow obstruction of the subjects with chronic pulmonary disease.

Animal models in chronic obstructive pulmonary disease-an overview

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airway obstruction resultant from an augmented inflammatory response of the respiratory tract to noxious particles and gases. Previous reports present a number of different hypotheses about the etiology and pathophysiology of COPD. The generating mechanisms of the disease are subject of much speculation, and a series of questions and controversies among experts still remain. In this context, several experimental models have been proposed in order to broaden the knowledge on the pathophysiological characteristics of the disease, as well as the search for new therapeutic approaches for acute or chronically injured lung tissue. This review aims to present the main experimental models of COPD, more specifically emphysema, as well as to describe the main characteristics, advantages, disadvantages, possibilities of application, and potential contribution of each of these models for the knowledge on the pathophysiological aspects and to test new treatment options for obstructive lung diseases.

Necrose Asséptica da cabeça do fêmur

Legg-Calvé-Perthes disease is a non-inflammatory aseptic necrosis of the head of the femur that is found in both young animals and humans before the gap in the femur head closes. In the fields of both human and veterinary medicine the cause of this condition is not known for certain. Various factors have been put forward in the literature as being responsible for the incidence of this condition such as: abnormalities in coagulation, changes in blood flow in the arteries, a septic obstruction in the draining of the epiphysis or the upper parts of the femur, trauma, growth cycle, hyperactivity in a child, genetic influences and dietary factors. Case histories in dogs show that the first stages of the condition progress slowly but that limping or putting weight on the limb worsens at 6 to 8 weeks. Some owners talk about a sharp onset in clinical lameness. Other clinical symptoms may include irritability, loss of appetite and knawing at the hair surrounding the affected hip. In the course of physical examination manipulating the hip joint will cause pain to the animal. The advanced stages of the disease may result in restricted amplitude of movement, muscular atrophy and fracturing. In humans the clinical signs are similar, although progression of the disease is slower so that it can be diagnosed at an earlier stage. In veterinary medicine the diagnosis is, in the main, based on case history, clinical symptoms, physical examination and certain related procedures such as radiography. The various diagnoses include physical trauma and dislocation of the medial patella. In human medicine many people have been correctly diagnosed. Whatsmore, there is a range of related procedures that are virtually not available to veterinary medicine such as magnetic nuclear resonance, that show up necroses with great clarity before radiography and cintilography do, and is considered...

Platinosomíase em felinos domésticos: um diferencial para obstrução biliar

The platinosomiase is a disease the hepatobiliary system of domestic felines being caused by trematode Platynosomum fastosum. The life cycle of the parasite includes the presence of three intermediate hosts (snails, terrestrial isopodes, lizards or frogs). The cat is considered definitive host of the parasite and acquires the infection eating a vertebrate intermediate host containing metacercariae. The adult parasites generally inhabit the liver, gallbladder and bile ducts of cats. The severity of clinical manifestations depends mainly on the number of flukes in the biliary tract. Many animals are asymptomatic or exhibit nonspecific clinical manifestations such as anorexia, lethargy, weight loss, vomiting and diarrhea. In large infestations can occur biliary obstruction resulting in jaundice, cirrhosis, hepatitis cholangiohepatitis and even death. The definitive diagnosis is accomplished through by the detection of fluke eggs in feces or through laparotomy and liver biopsy. Treatment should be based on the use of anthelmintic for the elimination of the parasite and supportive therapy for the animal. Prevention is difficult due to predatory nature of the cat. The control can be accomplished through periodic fecal examinations
