Uso do spoligotyping para genotipagem de Mycobacterium tuberculosis obtidos a partir de lâminas coradas pela técnica de ziehl-neelsen pertencentes a pacientes com tuberculose pulmonar residentes nos municípios paraenses de Belém e Ananindeua, Pará, Brasil

A tuberculose (TB) é um grande problema de saúde pública, intimamente ligada aos fatores sócio-econômicos, e tem como principal agente etiológico o Mycobacterium tuberculosis. O Spoligotyping é uma técnica baseada em PCR-hibridização reversa que permite detectar e diferenciar simultaneamente membros do Complexo M. tuberculosis diretamente de amostras clínicas, como em amostras obtidas de lâminas de Ziehl-Neelsen (ZN), evitando problemas associados ao lento crescimento destes microrganismos, tornando-se assim uma importante ferramenta para o monitoramento de cepas em diferentes contextos epidemiológicos, sendo capaz de revelar o caráter biogeográfico destas. A possibilidade de caracterizar genética, demográfica e geograficamente estes microrganismos pode contribuir para o entendimento de como a doença é transmitida e para a implementação das ações para seu controle e combate. Desta forma, foi realizado um estudo retrospectivo que avaliou amostras obtidas a partir de lâminas coradas pela técnica de ZN, confeccionadas por laboratórios da rede pública dos municípios paraenses de Belém e Ananindeua entre outubro de 2007 e março de 2008. A maioria (61,3%) dos 163 casos incluídos no estudo pertencia ao gênero masculino e 68,0% dos casos tinham entre 20 e 49 anos, com média de idade de 38 anos. A aplicação do Spoligotyping neste tipo de amostras apresentou bom rendimento, com 146 (89,6%) padrões de hibridização completos e concordantes entre si após as duplicatas. Destes, 142 foram considerados para comparação com o banco de dados internacional de Spoligotyping (SpolDB4), dentre os quais foram observados 67 espoligotipos ou genótipos distintos, compreendendo 95 (67%) casos com padrões compartilhados por duas a 20 amostras e 47 (33%) casos com padrões únicos. Quarenta e oito (71,6%) genótipos eram conhecidos e 19 (28,4%) ainda não haviam sido relatados no SpolDB4. As famílias LAM e T foram as mais frequentes, concentrando 56 (39,4%) e 35 (24,6%) casos, respectivamente, e as famílias Haarlem e EAI compreenderam 12 (8,45%) amostras cada. A geolocalização dos casos permitiu visualizar a distribuição dos espoligotipos nos municípios estudados, evidenciando alguns agrupamentos com mesmo genótipo, mostrando-se útil para direcionar e auxiliar investigações futuras.

Cor triatriatum sinister e hipertensão arterial pulmonar secundária em cão

This paper describes the occurrence of cor triatriatum sinister, a rare cardiac malformation in dogs, associated with pulmonary edema and pulmonary hypertension in a 5-year-old Poodle female with history of acute dyspnea and cyanosis. The animal presented acute respiratory failure, heart failure with low cardiac output, progressing to acute tubular necrosis and death. The diagnosis was made posmortem due to the clinical instability of the dog. This malformation was diagnosed by the subdivision of the left atrium into two compartments separated by an abnormal fibromuscular membrane, absence of structural abnormalities of the mitral valve and thickening of pulmonary artery tunica media associated with renal tubular degeneration. The occurrence of cor triatriatum in dogs is most common in the right atrium, defined as cor triatriatum dexter. Additionally, pulmonary arterial hypertension associated with this malformation is described only in humans with this heart defect.

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.

Eletroestimulação em pacientes portadores de doença pulmonar obstrutiva crônica

Patients with Chronic Obstructive Pulmonary Disease may have muscle dysfunction, which ultimately reduce the functional capacity. Neuromuscular electrical stimulation (NMES) is a technique that can be effective in these patients, and implies low overload to the cardiorespiratory system. The aim of this study was to investigate the effects of NMES on muscle strength and cardiorespiratory fitness in COPD patients. Five patients (2 men, 3 women) were evaluated, with a mean age of 70.40 ± 6.61 years, and underwent anamnesis, anthropometric measurements, spirometry, pulmonary function, cardiopulmonary functional capacity and muscle strength in the lower limbs. After the evaluations, the patients were enrolled in a program of electrical stimulation of the quadriceps muscles, performed 3 times per week for 5 weeks. Each session lasted for 30 minutes, being reassessed at the end of the 15 sessions. Statistically significant response is observed to gain strength in lower limb (p = 0.005), but no significant responses were observed for the distance in six minute walking test before and after the test protocol for electrical stimulation. Showing that with NMES was located just gain muscle strength without effects on functional capacity, and there are few studies that investigate these effects, so further studies are needed to investigate this relationship.

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.

Função Pulmonar de pacientes submetidos a Cirurgia Bariátrica

Introduction: Obesity is a risk factor for postoperative pulmonary complications. Overweight can alter respiratory mechanics and decrease lung volumes and capacities. Bariatric surgery (BS) has been used as treatment for morbid obesity, but this surgery can lead to respiratory complications. Objective: To evaluate pulmonary function in morbid obese patients undergoing bariatric surgery. Methods: The patients were submitted to pulmonary function testing, including slow and forced vital capacity (SVC and FVC), forced expiratory volume in the first second (FEV1), Tiffenau index (FEV1/FVC), forced expiratory flow 25-75% (FEF25-75%) and maximal inspiratory and expiratory pressure (MIP and MEP). Descriptive analysis was performed. Results: We evaluated 18 patients, mean age of 37.33 ± 11.23 years, height 1.65 ± 0.09 m, weight 125.92 ± 25.24 kg and BMI 46.34 ± 9 20 kg/m2 , SVC 100.64 ± 22.91%, FVC 102.04 ± 21.82%, FEV1 104.85 ± 22.16%, FEV1 /FVC 83.54 ± 6.63% and FEF25-75% 84.47 ± 25.74%, 99.75 ± 24.55 for MIP and MEP 102.12 ± 25.06 cmH2O. Conclusion: The bariatric surgery candidates had normal values for manovacuometry and spirometry.

Hemorragia pulmonar induzida por exercício: fatores predisponentes, prevenção e tratamento

The Exercise Induced Pulmonar Haemorrhage (EIPH) affect a large amount of atlethe horses. It affects the horse's performance in any kind of competition and it can represent incresead spending of money or even an economic loss. Thoroughbred horses are the most affectef breed by EIPH because of intensive activity. Meanwhile any other kind of horse breed that is involved in athletic competition can also be affected by EIPH as well. In this brief work we are presenting the most common causes and factors from the EIPH as well the prevention and some types of treatment available nowadays
