An 8-year-old boy was evaluated for blunt abdominal trauma after a motor vehicle crash. In the course of his workup, a computed tomography (CT) scan of the abdomen was suspicious for a duodenal injury. At surgery, the duodenum was found to be normal; however, a rupture of the cisterna chyli was identified. This injury was repaired, and the boy made an uneventful recovery. This report is one of few in the literature describing isolated injury to the cisterna chyli after blunt abdominal trauma.

OBJECTIVE: Primary and secondary pulmonary hypertension have been associated with poor outcomes after single lung transplantation. Some groups advocate double lung transplantation and the routine use of cardiopulmonary bypass during transplantation in this population. However, the optimal procedure for these patients remains controversial. The goal of our study was to determine the safety of single lung transplantation without cardiopulmonary bypass in patients with secondary pulmonary hypertension. METHODS: We retrospectively reviewed 76 consecutive patients with pulmonary parenchymal disease who underwent single lung transplantation from 1992 to 1998. Recipients were stratified according to preoperative mean pulmonary artery pressure. Secondary pulmonary hypertension was defined as parenchymal lung disease with a preoperative mean pulmonary artery pressure of 30 mm Hg or more. Patients with primary pulmonary hypertension or Eisenmenger's syndrome were excluded from analysis. RESULTS: Eighteen of 76 patients had secondary pulmonary hypertension. No patient with secondary pulmonary hypertension required cardiopulmonary bypass, whereas 1 patient without pulmonary hypertension required bypass. After the operation, no significant differences were seen in lung injury as measured by chest radiograph score and PaO(2)/FIO(2) ratio, the requirement for inhaled nitric oxide, the length of mechanical ventilation, the intensive care unit or hospital length of stay, and 30-day survival. There were no differences in the forced expiratory volume in 1 second or 6-minute walk at 1 year, or the incidence of rejection, infection, or bronchiolitis obliterans syndrome greater than grade 2. Survival at 1, 2, and 4 years after transplantation was 86%, 79%, and 65%, respectively, in the low pulmonary artery pressure group and 81%, 81%, and 61%, respectively, in the group with secondary pulmonary hypertension (P >.2). CONCLUSION: We found that patients with pulmonary parenchymal disease and concomitant secondary pulmonary hypertension had successful outcomes as measured by early and late allograft function and appear to have acceptable long-term survival after single lung transplantation. Our results do not support the routine use of cardiopulmonary bypass or double lung transplantation for patients with this disorder.

BACKGROUND: Routine endocrine screening of idiopathic gynecomastia has been advocated, but may not be cost effective. We carried out a cost-benefit analysis of this approach. METHODS: A retrospective study (1992 to 1997) of 87 adult males with symptomatic gynecomastia was performed. RESULTS: Thirty-four (39%) patients had extrinsic causes; 53 (61%) were considered idiopathic. Forty-five idiopathic cases underwent endocrine testing: beta human chorionic gonadotropin alone, 16; and beta human chorionic gonadotropin, LH, estradiol, testosterone+/-testicular ultrasound, 29. One (2%) occult Leydig cell testicular tumor was detected. Forty-four patients had normal studies and remain well after local excision. CONCLUSION: Routine endocrine evaluation of idiopathic gynecomastia is rarely productive; such testing is best done selectively.
