RESUMO
In this study, serial bacteriological samples including oropharyngeal, endotracheal and lower respiratory tract samples were collected from 20 patients in the respiratory intensive care unit [ICU] who were intubated and mechanically ventilated for at least 3 days. The results of this study showed the prevalence of gram negative bacilli in all bacteriological samples. The lower respiratory tract specimens were collected by the protected specimen brush catheter [PSB catheter] which was useful in both the bacteriological culture and colony count of these specimens to differentiate between colonization and true infection. So, we may recommend its use routinely in bacteriological sampling of such specimens

Sixty patients with vitiligo were subjected to clinical and investigative studies to discover a possible diabetic tendency. Family history of D.M. was found in 30% of vitiligo patients. Patients were subjected to urine analysis, fasting blood sugar, oral glucose tolerance test, augmented cortisone glucose tolerance test, intravenous glucose tolerance test, and intravenous insulin sensitivity test. The results achieved revealed the presence of a relationship between vitiligo and D.M., 46% of vitiligo patients have a prediabetic tendency. A survey done on 200 diabetic patients disclosed an incidence of vitiligo in 4% of them; in 87% of them the viiligo proceeded the onset of diabetes by many years
