Polycythemia vera (PV) is a chronic myeloproliferative disorder characterized by predominant proliferation of erythroid precursors. Few data are available concerning Brazilian patients with this condition. The aim of this study was to describe clinical and demographic characteristics of PV patients at diagnosis and analyze their long-term outcomes. ⋯ The PV patients described here had long survival and arterial thrombotic events were the most important and common complication among this population.

Comparative Study
Postoperative study of vital capacity and ventilation measurements following elective craniotomy.
Changes in pulmonary function commonly occur after general surgery. The aims were to evaluate vital capacity, tidal volume and respiratory frequency among patients undergoing elective craniotomy and to determine possible correlations of these parameters with surgery duration and etiology for neurosurgery. ⋯ Reductions in VC, TV and VE were observed during the postoperative period in patients undergoing aneurysm clipping or tumor resection. The reductions in VC and TV were greater in patients undergoing craniotomy due to aneurysm and with longer surgery duration.

Women infected by HIV are more likely to have cervical cancer and its precursors. Treatment of the precursor lesions can prevent this neoplasia. The aim of this study was to assess the likelihood of recurrent cervical intraepithelial neoplasia grades 2 or 3 (CIN 2-3) in HIV-infected women, compared with HIV-negative women, all treated by large loop excision of the transformation zone (LLETZ). ⋯ After LLETZ there is a higher risk of recurrence of CIN 2-3 among HIV-positive women than among HIV-negative women. This higher risk was not influenced by margin status or grade of cervical disease treated. The use of HAART may decrease the risk of this occurrence in HIV patients.

The choice of an antihypertensive drug is based on several criteria and specific situations give rise to doubt and controversy. The aim here was to evaluate physicians approaches towards treatment with antihypertensive agents in specific situations. ⋯ Most physicians adopted the correct approach, but some had an alternative strategy for the same situations that was not based on evidence.

Stuttering is a complex disease that influences occupational, social, academic and emotional achievements. The aim of this study was to correlate the stuttering severity index with speaking rates of mothers and children. ⋯ The results suggest that the mothers speaking rate should be incorporated in the assessment and treatment of stuttering.
