Microbiological diagnosis of pneumonia allows the optimal use of antibiotics in mechanically ventilated patients. That is why samples of bronchoscopic bronchoalveolar lavage had been quantitatively cultivated, but this procedure is not always possible. ⋯ Concordance between non-bronchoscopic and bronchoscopic bronchoalveolar lavage is good in mechanically ventilated patients with pneumonia. However, the use of antibiotics previously, but not the time of pneumonia presentation, significantly decreases that concordance.

Diagnosis of acute appendicitis is difficult in nearly 30% of patients with pain in low right quadrant. Diagnostic imaging may provide a means of a more accurate diagnosis. ⋯ Imaging diagnostic methods, in cases of abdominal pain suspected to be appendicitis, are more cost-effective than physical exam to make accurate diagnostic decisions. Tomography offers the best cost-effectiveness in prepaid system and in public health system.

Diagnosis of apendicitis is difficult; however several clinical scales have been developed that attempt to improve diagnostic accuracy. ⋯ For men with abdominal pain on right lower quadrant, surgeon diagnosis is more accurate than scales. For women, Fenyö scale offers a better sensitivity. Alvarado score can facilitate decision-making in patients with these abdominal symptoms.

In Brazil, capybaras (Hydrochoerus hydrochaeris) are important hosts for Amblyomma ticks, which in turn can transmit rickettsiae to humans and animals. Therefore, capybaras are potential sentinels for rickettsial infection. ⋯ The first evidence is reported of R. bellii natural infection in vertebrate hosts, and the first evidence of R. parkeri infection in capybaras. While R. parkeri is known to infect and cause disease in humans, no similar evidence for human infection has been indicated by R. bellii.
