The objective of this study was to investigate the influence of storage conditions on the physicochemical (mass, albumen height, pH, and Haugh unit) and microbiological (Salmonella spp., determination of the Total and Thermotolerant Coliforms, and Counting of the Mesophilic Aerobic Bacteria) quality of eggs. In the first experiment, a questionnaire was applied, and 33 samples of eggs were collected for the Salmonella spp analysis. In the second experiment, the eggs were collected from supermarkets, open markets, and distributors for physicochemical analysis. In the third experiment, 175 eggs were collected from the distributor, packaged in cardboard boxes lined with plastic wrapping, stored at 5 °C and 28 °C, and the physicochemical and microbiological analyses were performed at 7, 14, and 21 days of storage. In the first experiment, 100% of the samples analyzed showed no Salmonella spp. In the second experiment, it was found that the values of physicochemical parameters were in agreement with those in the literature. However, in the third experiment, the physicochemical parameter results showed statistical difference during storage and temperatures studied. Salmonella spp. were found in the samples stored at room temperature and in the refrigerated samples. Mesophilic microorganisms with values ranging from <10 CFU g- 1 (estimated) to 8.0 × 10³ CFU g- 1 and coliforms to 4 NMP.g- 1 were also found, but the presence of E. coli was not confirmed.

A ausência congênita do pericárdio é uma anomalia congênita rara, de difícil diagnóstico. Relatamos um caso de paciente de 42 anos, com dor torácica atípica, eletrocardiograma com distúrbio de condução no ramo direito, radiografia de tórax com desvio do eixo cardíaco no sentido anti-horário e ecocardiograma sugerindo sobrecarga de volume do ventrículo direito. Cateterismo cardíaco demonstrou ausência de shunts intracardíacos, e rotação e deslocamento do coração para o hemitórax esquerdo. Ressonância nuclear magnética confirmou o diagnóstico ao demonstrar ausência parcial do pericárdio à esquerda, com interposição do parênquima pulmonar entre o tronco da artéria pulmonar e a aorta.

Agenesis of the pericardium is a rare congenital anomaly, which is difficult to diagnose. We report a case of a 42-year-old patient, with atypical chest pain, electrocardiogram with an incomplete right bundle branch block, chest X-ray with a counterclockwise heart axis deviation and echocardiogram suggesting right ventricle volume overload. Cardiac catheterization showed no intracardiac shunts, and rotation and displacement of the heart into the left hemithorax. Magnetic nuclear resonance imaging confirmed the diagnosis by revealing partial absence of the left pericardium, with interposition of lung parenchyma between the main pulmonary artery and the aorta.
