[Use of transcranial Doppler in monitoring cerebral vasospasm secondary to subarachnoid hemorrhage].
Cerebral vasospasm accounts for an increased morbidity and mortality in patients with spontaneous subarachnoid hemorrhage (SAH). Its early and non invasive detection by transcranial Doppler (TCD) may contribute to a better prognosis in such cases. ⋯ TCD is a valuable auxiliary method in the detection of cerebral vasospasm (even pre-symptomatic) secondary to SAH, allowing a more precocious therapeutic intervention. Our results are similar to those described in the literature.

Comparison of three modes of MV: intermittent mandatory ventilation with positive end expiratory pressure (IMV + PEEP), APRV and continuous positive airway pressure (CPAP) in children during cardiac surgery post operative with pulmonary hypertension and mild or moderate pulmonary lesion. ⋯ Due to the methodology utilized MAP was higher with APRV resulting in an increased tidal volume without respiratory or cardiocirculatory adverse effects when the three modes were compared. Our results suggest that APRV is a simple and safe method of ventilation.

Comparative Study
[Respiratory morbidity in patients with and without pulmonary obstructive syndrome after upper abdominal surgery].
We wanted to determine the postoperative pulmonary complication after upper abdominal surgery in patients with pulmonary obstrutive syndrome. ⋯ The incidence of postoperative pulmonary complications was strongly associated with the presence of pulmonary obstructive syndrome.

Anatomo-pathological correlation in a case of systemic talc granulomatosis affecting lungs, pleura, liver, spleen and mesenteric lymph nodes resulting in pulmonary arterial hypertension and cor pulmonale is described. The patient, a 26-year-old male HIV-negative intravenous drug addict had no lymphopenia or any histopathologic findings at necroscopy compatible with AIDS, despite of a chronic high-risk behavior favoring this illness.
