Acute massive hydrothorax complicating peritoneal dialysis, report of 2 cases and a review of the literature.

Acute massive right-sided hydrothorax is a relatively rare but serious complication of peritoneal dialysis and may be responsible for the development of dyspnea during peritoneal dialysis. The pleural fluid appears to arise from the peritoneal dialyzate based on the time of its appearance and its chemical composition. It should be included in the differential diagnosis when a patient becomes dyspneic during peritoneal dialysis along with exaccerbation of congestive heart failure, pneumonia, atelectasis, and purulent bronchitis. Its occurrence is an indication to stop the peritoneal dialysis and contraindicates further use of this form of dialysis. Treatment may be conservative or aggressive (thoracentesis) depending on the clinical condition of the patient. Etiology is poorly understood. In some cases, there may be traumatic diaphragmatic fenestrations, but the majority of cases appear to be due to less well defined communications between the peritoneal and pleural spaces.

Respiratory function and symptoms in urban office workers in relation to oxidant air pollution exposure.

Similar populations of male and female office workers in San Francisco, which has little air pollution, and in Los Angeles, which experiences frequent photochemical smog episodes, were surveyed in an attempt to document excess respiratory symptoms and dysfunction in Los Angeles relatable to air pollution. Most results of forced expiratory tests, single-breath N2 tests, and questionnaire interviews did not differ significantly between cities. Los Angeles women reported nonpersistent cough and phlegm more often than did San Francisco women. Smokers in both cities showed increased functional abnormalities. These results suggested that Los Angeles oxidant exposure is far less significant than smoking as a risk factor in development of chronic respiratory disease in sedentary indoor workers in good general health. Oxidant exposure has not been ruled out as a significant risk to more heavily exposed on more highly susceptible persons.
