Chlamydia pneumoniae has recently been identified as a cause of lower respiratory tract infections. From March 1987 to March 1988, 259 university students-151 students with lower respiratory tract infections and 108 controls-from the University of California, Berkeley, were studied to determine the incidence and pattern of C pneumoniae lower respiratory tract infections. Serologic evidence of a recent C pneumoniae infection was found in less than 2%, and the organism was not isolated from any of the subjects. Despite the paucity of evidence of a recent infection, 47.5% of this university population showed serologic evidence of a previous C pneumoniae infection. The lower incidence of C pneumoniae infection in our population, when compared with previous reports, suggests that there may be geographic and temporal differences or fluctuations among populations.

We encountered seven female adolescents with the Fitz-Hugh-Curtis syndrome and no signs or symptoms of salpingitis. Six of the patients had cervical cultures positive for Chlamydia trachomatis. The Fitz-Hugh-Curtis syndrome should be included in the differential diagnosis of right-sided abdominal pain in the sexually active female adolescent to avoid unnecessary diagnostic procedures and to reduce the prevalence of chlamydial infection and its complications.

Alcohol is a frequently abused drug among adolescents. In adults, alcohol alters iron metabolism, predisposing to excess hepatic iron storage and, possibly, liver damage. The purpose of this study was to determine whether alcohol is associated with an elevated serum iron concentration and transferrin saturation in adolescents, and to determine the contribution of oral contraceptive use to these abnormalities. Adolescents (591 male and 614 female) aged 16 to 19 years, who participated in the first National Health and Nutrition Examination Survey from 1971 to 1973, were grouped according to their reported frequency of alcohol intake. Drinking frequency was associated with serum iron concentrations in boys and girls, and with total iron-binding capacity, transferrin saturation, and hemoglobin concentration in boys. Alcohol use was associated with an elevated serum iron concentration only in oral contraceptive nonusers. Adolescents who use alcohol have an elevated serum iron concentration, and male alcohol users have an increased transferrin saturation as well. These abnormalities may be precursors of hepatic iron overload and chronic liver damage.
