Lesões pulmonares em suínos abatidos no matadouro Público Municipal de Esperança, Paraíba / Pulmonary lesions of slaughtered pigs at the municipal public slaughterhouse of Esperança, Paraíba

O objetivo do presente estudo foi avaliar as lesões macroscópicas e histológicas em pulmões de suínos abatidos no abatedouro público de Esperança, Paraíba. Foram inspecionados pulmões de 180 suínos entre julho e dezembro de 2013. Destes, 34 (18,8%) apresentaram lesões. Na análise anatomopatológica dos fragmentos coletados, 82,3% (28/34) exibiram lesões sugestivas de Pneumonia Enzoótica Suína (PES). Seis (17,7%) amostras apresentaram alterações causadas pela distribuição irregular de sangue. Casos sugestivos de PES crônica foram observados em 57,1% (16/28) dos fragmentos coletados. Em 42,9% (12/28) das amostras foram definidos como sugestivos de PES subaguda. Nenhum pulmão apresentou lesões sugestivas de PES aguda. A pesquisa demonstrou que lesões pulmonares em suínos são frequentemente detectadas no abatedouro de Esperança, Paraíba, sendo a maioria destas lesões sugestivas de PES.

The objective of the present study was to evaluate the macroscopic and histological lesions in the lungs of slaughtered pigs at the public slaughterhouse of Esperança, Paraíba. Lungs from 180 pigs were inspected between July and December 2013. Lesions were observed in 34 (18.8%) lungs. In the anatomopathological analysis of the collected fragments, 82.3% (28/34) presented suggestive lesions of Swine Enzootic Pneumonia (SEP). Six (17.7%) samples presented alterations caused by irregular blood distribution. Suggestive cases of chronic SEP were observed in 57.1% (16/28) of the collected fragments. In 42.9% (12/28) of the samples were defined as suggestive of subacute SEP. No lungs presented lesions suggestive of acute PES. The research showed that lung lesions in pigs are frequently detected in the Esperança, Paraíba slaughterhouse, with the majority of these lesions suggestive for SEP.

Aislamiento e identificación de agentes virales en niños con infecciones respiratorias agudas / Isolation and identification of viral agents in children with acute respiratory infectiuos diseases

Las infecciones respiratorias agudas de etiología viral ocupan el primer lugar de morbilidad en la población pediátrica a nivel mundial. El propósito de este estudio fue identificar los virus respiratorios como agentes etiológicos de estas infecciones en los niños que consultaron al Servicio de Pediatría del Hospital Universitario de Caracas. Se incluyeron pacientes entre 0 y 11 años que consultaron por infecciones respiratorias agudas. Se realizó encuesta epidemiológica y clínica y se tomaron las muestras (hisopado nasofaríngeo) para identificación y aislamiento de los virus respiratorios (influenza A y B, para influenza 1, 2, y 3, adenovirus y virus sincitial respiratorio) por inmunofluorescencia y cultivo. Durante 7 años se evaluaron 583 niños, el estudio virológico fue positivo en 83 pacientes (14,2 por ciento) correspondiendo 72,3 por ciento al virus para influenza 1,15,7 por ciento virus influenza A, 6 por ciento influenza B, 4,8 por ciento adenovirus y 1,2 por ciento al virus para influenza 3. Los hallazgos coinciden con la epidemiología en el país para el período del estudio. Se demostró la circulación de los virus para influenza 1 y 3,influenza A y B y adenovirus.

Respiratory viral infections are the first cause of morbidity in children worldwide. The purpose of this study was to know the viral etiology of acute respiratory infections in the Pediatric Department of the “Hospital Universitario de Caracas”. We investigated children 0-11 years with acute respiratory infections for viral etiology. The diagnosis was made by identification of respiratory viruses from nasopharyngeal swab (influenza A and B, parainfluenza 1,2, and 3, adenovirus and respiratory sincitial virus) by inmunofluorescence and culture. 583 patients were investigated. Respiratory viruses were detected in 14,2% cases, with parainfluenza type 1 virus the most commonly detected (72,3%), followed by influenza A 15,7%, influenza B 6%, adenovirus 4,8% and parainfluenza 31,2%. The virology results were similar to the epidemiological reports of the Health Services during the period of the investigation. It was demonstrated the circulation of parainfluenza viruses 1-3, influenza A and B and adenoviruses.

Respiratory system assessment of marine spray painting workers

Workers at the Marine Spray Painting Workshop [MSPW] are exposed to respiratory hazards durig ship surface preparation and spray painting. To identify hazards at the Marine Spray Painting Workshop [MSPW] and assess the impact of these hazards on the respiratory system of Marine Spray Painters [MSPs]. The study included 80 workers, of these were 40 MSPs from the Alexandria Shipyard Company. The rest were control workers, not exposed to respiratory hazards in their work environment. All MSPs and unexposed workers were subjected to an interviewing schedule; to collect data on personal characteristics, occupational, and medical history. The Medical Research Council [MRC] questionnaire was used, it included questions on respiratory symptoms, and diseases. All workers underwent a general clinical examination, a local chest examination, pulmonary function tests, and lung imaging by conventional chest radiographs [CCR]. The present study demonstrated that breathlessness grade IV, wheeze, and bronchial asthma, were significantly more encountered among MSPs compared with unexposed workers. On assessing lung functions, mean percent predicted values of lung function indices [LFI] reflecting large and small-airway functions were lowered among MSPs compared with unexposed workers, but the lowering was not statistically significant. Furthermore, it was found that 47.5% of MSPs had no radiological abnormalities [0/0 ILO profusion grade], while 52.5% of MSPs were either with suspicious radiological abnormalities of [0/1 or 1/0 ILO profusion, glade] [10.00%] or with definite radiological abnormalities whose ILO profusion grade was of [2/1, 2/2, or 2/3 ILO profusion grade] [10.00%, 17.5%, or 15.0% respectively]. A comparison between silicotic and non-silicotic MSPs was conducted, where no significant differences were found between them regarding respiratory symptoms, diseases, and spirometric measurements, thus, the significant increase in bronchial asiluna among MSPs in the present study can be attributed to exposure to HDI during spray painting. The study revealed a significant positive correlation between grade of profusion and age, duration of exposure and breathlessness, especially those with profusion grade >/= 1/1, but no significant correlations between the grade of profusion and mean values of spirometric measurements were recorded. A potential respiratory health hazard exists at the [MSPW] in Alexandria Shipyard Company and the level of protection for workers should be increased

Clinical and endoscopic findings in the mucosae of the upper respiratory and digestive tracts in post-treatment follow-up of paracoccidioidomycosis patients

Foi realizado sistematicamente o exame das vias aereas-digestivas superiores (VADS) em grupo e 80 pacientes de paracoccidioidomicose (PCM) acompanhados apos o tratamento especifico por periodo que variou de 8 a 17 anos. A musoca das VADS estava comprometida antes do tratamento especifico em 74 pacientes, assim distribuidos: orofaringe, 50 (41 isoladamente, 7 em associacao com o laringe e 2 com a mucosa nasal); laringe, 30 (23 isoladamente e 7 em associacao) e nasal, 3 ( 1 isoladamente e 2 em associacao). Em todos os 50 que apresentavam lesoes inativas, 3 com cicatriz viciosa (1 com retracao de lingua e 2 diminuicao de orificio oral). Houve lesao destrutiva em 1 caso com perfuracao do palato. Nos 46 casos restantes, o exame mostrou cicatriz estriada branco nacarada em alguns quase iperceptivel e em outros com retracao parcial de estruturas anatomicos sem alteracoes de suas caracteristicas.
