Bullous emphysema. Progressive incremental exercise testing to evaluate candidates for bullectomy.
Various tests of both function and anatomy have been used in patients being considered for surgical resection of giant pulmonary bullae. A young patient had an excellent response to removal of a large bulla in the right lung. In addition to roentgenographic evaluation, ventilation perfusion scanning, and routine preoperative pulmonary function studies, we performed progressive incremental exercise testing to determine both preoperative and postoperative ventilatory and cardiac measurements. We feel that progressive incremental exercise pulmonary function adds another dimension to the selection and follow-up of patients being considered for operative bullectomy.
Hernia of Morgagni's foramen presenting as asymptomatic pleural mass.
An asymptomatic 64-year-old black man presented with an enlarging left pleural mass. Preoperative evaluation failed to reveal an etiology. At thoractomy omental fat was found along the diaphragm, extending to the left costophrenic angle, and protruding through a hernia of Morgagni's foramen. The omentum was replaced into the abdomen and the defect was repaired.

Idiopathic bronchial stenosis in a young woman.
An 18-year-old white woman presented with a severe obstructive ventilatory defect. An evaluation revealed a stenotic lesion of the right bronchus intermedius and the left mainstem bronchus. Treatment with prednisone followed by beclomethasone resulted in a marked improvement in her condition.

The admission urinalysis: impact on patient care.
Although urinalysis is one of the most frequently ordered tests in primary care, its usefulness in screening has not been demonstrated. A retrospective review of 1,607 admission urinalyses for inpatients in a referral/community hospital identified 861 as clinically indicated and 746 as routine. Routine urinalyses were abnormal less frequently than clinically indicated urinalyses (18.1% vs 39.6%) and when abnormal, were responded to less often (33.3% vs 75.4%). Forty-five (6.0%) of the routine urinalyses yielded an abnormality that led to diagnostic action. Of these, 18 were normal on repeat testing and 17 were considered unlikely to represent significant disease. Therefore, only ten (1.3%) of the routine urinalyses affected patient therapy. In eight of these cases, the abnormality was pyuria, of which six proved to be asymptomatic bacteriuria. The admission urinalysis as a routine test had little impact on patient care in the authors' institution.
