An angiographic dilemma: bronchopulmonary sequestration versus pseudosequestration: case reports.

Bronchopulmonary sequestration is a congenital anomaly in which part of the pulmonary tissue is detached from the normal lung and is supplied by anomalous systemic arteries. The sequestered, aberrant lung tissue does not have normal connections with the tracheobronchial tree or pulmonary arteries. In some patients with angiographic characteristics of this disorder, no sequestration is found at the time of surgery. We present three cases in which systemic arterialization of a portion of lung occurred without actual sequestration. Such cases of pseudosequestration can present a diagnostic challenge preoperatively and should be considered whenever angiographic findings compatible with bronchopulmonary sequestration are found.

Upper airway obstruction due to tuberculosis. Treatment by photocoagulation.

We describe here a case of endotracheobronchial tuberculosis involving both the trachea and major bronchi. Endobronchial carcinoma was suspected initially, even at the time of bronchoscopy. Later, despite improvement of the pulmonary infiltrate and clinical symptoms after chemotherapy, upper airway obstruction occurred. Repeat bronchoscopy showed a distal tracheal nongranulomatous, fibrogranular stenotic lesion. Laser therapy was then employed to reduce the stenosis.

A controlled comparison of dipyrone and paracetamol in post-episiotomy pain.

A double-blind, placebo-controlled trial was carried out in 299 patients suffering from post-episiotomy pain to compare the analgesic effectiveness and tolerance of single doses of 500 mg dipyrone and 500 mg paracetamol. Assessments of pain relief over a 6-hour period showed that dipyrone produced significantly better results than placebo within half an hour of intake and maintained this superiority throughout the 6 hours. It also afforded consistently better pain relief than paracetamol and was significantly more effective at the 6-hour assessment. Side-effects were few and mild.
