This paper presents the results of histologic studies conducted in the context of tenosynovectomy of the flexor tendons to treat carpal tunnel syndrome. The most common findings were inflammatory changes of the synovial sheath, vascular pathology and fibrous changes of the connective tissue.

Twenty-five patients with clinical and CT findings indicating supratentorial cerebral infarct were prospectively studied with MR. MR examinations were performed between the 3rd and 150th day after stroke. T2-weighted axial images were compared with T1-weighted sequences after i.v. administration of Gd-DTPA. T2-weighted images demonstrated parenchymal lesions in all 25 patients. Postcontrast T1-weighted images, however, displayed pathologic contrast enhancement in only 19 areas of infarction. In 5 of the 25 patients, the use of Gd-DTPA provided additional diagnostic information by demonstrating gyral contrast enhancement as a pattern typical for ischemia. In 2 of the 25 patients, pathologic contrast enhancement was observed in an area that was isointense to the surrounding brain tissue on the T2-weighted images. In one patient, Gd-DTPA improved differentiation between areas of subacute and chronic infarction. At present, in the patient with suspected cerebral infarction, MR imaging after i.v. administration of Gd-DTPA appears recommended when clinical findings and CT are equivocal.

Introduction: Medical residency can cause burnout syndrome, a physical, emotional and mental state of extreme exhaustion. Objective: This research sought to describe and analyze the prevalence of burnout in resident physicians linked to a teaching Hospital and to verify whether there is a correlation with sociodemographic and socioeconomic data. Method: This is an analytical, cross-sectional and quantitative study using the MBI (Malasch Burnout Inventory) version HSS (Human Services Survey), the Brazilian Economic Classification Criterion (CCEB) of ABEP and sociodemographic questions. Result: Of the enrolled residents, 102 participated in the survey. Of these, 76.47% showed a high level in at least one of the three domains of the burnout index and 21.57% of the residents showed a high level of burnout. There was a significant relationship between a larger number of children and the presence of emotional exhaustion (P=0.047), a higher frequency of depersonalization for surgical area residents (P=0.013) and reduced professional accomplishment, with an average income of R$ 2,965.69 and R$ 10,386.52 (P=0.006). No significant relationship was found between burnout and sociodemographic and socioeconomic variables. Conclusion: The results show that resident physicians are exposed to situations that contribute to high levels of stress and distress. Further studies on the subject are still necessary.

The following dopamine-2-receptor occupancy data (in percentages) were obtained in the study: Conclusion: Via PET analysis it was possible to demonstrate, that tiapride is also in vivo a powerfull dopamine-Z-receptor antagonist. Initial dose/occupancy relationships could be determined.
