Despite a declining prevalence secondary to improved prophylaxis, Pneumocystis carinii remains an important pulmonary pathogen in the immunocompromised host. Because the radiologist is often the first to suggest the diagnosis of PCP, an awareness of the entire spectrum of imaging features associated with this organism is important. The classic presentation of PCP is a bilateral interstitial pattern, which may be characterized as finely granular, reticular, or ground-glass opacities. When chest radiographic findings are normal or equivocal, high-resolution CT may be helpful, because it is more sensitive than chest radiographs for detecting PCP. The classic CT finding is extensive ground glass attenuation. Increasingly recognized characteristic patterns of PCP in AIDS patients include cystic lung disease, spontaneous pneumothorax, and an upper lobe distribution of parenchymal opacities. Although the radiographic findings in PCP are similar for AIDS and non-AIDS immunosuppressed patients, cystic lung disease has not been described in the latter patient population.
Presented herein is a case of a patient who, during a laparoscopic herniorrhaphy, developed profound bradycardia upon introduction of the pneumoperitoneum. Following discharge, the patient presented 24 h later with herniation through the trocar port incision. With laparoscopic surgery being used more frequently, there will be an increase in the incidence of these types of complications; however, with better awareness, they may be avoided.

Laparoscopic surgery impacted the surgical world in the United States in 1990. This report reviews the initial experience of 34 surgeons in 8 teaching hospitals of the Northeastern Ohio Universities College of Medicine. There were 538 cases reported from May 1, 1990 to January 31, 1991. There was no mortality and the morbidity rate was 4.8%, including three bile duct injuries. The conversion rate to an open procedure was 6.1%. The criteria for credentialing, training, and resident and faculty education are included. The data reported by the Surgery Department of Northeastern Ohio Universities College of Medicine are very similar to reported series from the current literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
