Macroscopic, Histological, and Microbiological Characterization of Contact Lesions at the Tibiotarsal Region of Broilers.

Brazil is considered as a great broiler feet exporter, especially for the Chinese trade. Contact lesions at the tibiotarsal region are responsible for economic losses and there is no model for its classification, thereby this study presents a fast and practical grade system to be used in the poultry industry and proposes these lesion characterizations into three different grades. For this, correlation was made between macroscopic, histological findings and microbiological quantification (, spp.

Does coronary Atherosclerosis Deserve to be Diagnosed earlY in Diabetic patients? The DADDY-D trial. Screening diabetic patients for unknown coronary disease.

Objectives: To evaluate if screening and treatment of asymptomatic coronary artery disease (CAD) are effective in preventing first cardiac event in diabetics.

Methods: Diabetic patients without known CAD were randomly assigned to undergo a screening for silent myocardial ischemia followed by revascularization or to continue follow-up. The reduction of cardiac death (CD) or nonfatal myocardial infarction (MI) represented the primary aim; secondary aim was the prevention of heart failure (HF).

Evaluation of three sampling methods for the microbiological analysis of broiler carcasses after immersion chilling.

Countries have different official programs and implement different sampling methods for the detection of Salmonella on poultry carcasses. In Brazil, a 25-g sample of skin and muscle excision (SME) from the wings, neck, and pericloacal parts is used; in the European Union (EU), a 25-g sample of neck skin (NSE) is used; and, in the United States, the whole carcass is rinsed with 400 ml of diluent (WCR). In the present study, these methods were evaluated to compare Salmonella occurrence and counts of hygiene indicator microorganisms (Escherichia coli, Enterobacteriaceae, and total viable count of aerobic mesophilic bacteria) using different carcasses from the same flock and also using different analytical units taken from the same carcass.

[Possibility of evaluation of chest pain at the time of hospitalization].

A series of 140 patients admitted to an Internal Medicine or a Cardiology Department for an acute chest pain is examined in order to evaluate the possibility of reaching a quick diagnosis, particularly for coronaric heart diseases, according with history, physical examination, electrocardiogram. In most of cases it was possible an immediate, correct evaluation of the patients, but in some cases a right diagnosis was achieved only after a period of observation and different investigations.
