Vaginal douching and the risk of tubal pregnancy.

To explore the possible association between vaginal douching and tubal pregnancy, we interviewed 273 women who were diagnosed with tubal pregnancy at Group Health Cooperative between September 31, 1981 and October 1, 1986. Their responses were compared with responses of a random sample of 722 female members of Group Health Cooperative who were assumed to be at risk of becoming pregnant at the time the cases conceived. After adjusting for differences between cases and controls with regard to other measured risk factors, we found a modest increase in risk associated with having douched more than two times per year in the past (RR = 1.3, 95% CI: 0.9-1.8). Among women who had more than one sexual partner during their lifetime, however, the risk for those who had douched more than twice per year was somewhat higher (RR = 1.6, 95% CI: 1.1-2.3). There was an indication that women who had been exposed to Chlamydia trachomatis, as indicated by elevated antibody titers, may further increase their risk for tubal pregnancy by douching (RR = 2.4, 95% CI: 0.8-7.3). The associations found in other studies between douching and pelvic inflammatory disease, and between pelvic inflammatory disease and subsequent tubal pregnancy, argue that a relation between douching and tubal pregnancy might be anticipated. Our results offer further support for this hypothesis.

The effect of respiratory viral infections on patients with cystic fibrosis.

We examined, in a 2-year prospective study, the frequency of respiratory viral infections in 19 school-age patients with cystic fibrosis and their unaffected siblings. At 2-month intervals throughout the study period, pulmonary function tests, oropharyngeal cultures, and serologic tests for respiratory viruses were performed in all subjects. Quantitative sputum cultures for bacteria were performed in subjects with cystic fibrosis. The same laboratory specimens were also collected at the time of all acute respiratory illnesses. Over the 2-year period, 398 viral cultures and serum samples were collected, 210 from patients with cystic fibrosis and 188 from their siblings. The frequency of culture-documented and seropositive viral infections was not significantly different between patients with cystic fibrosis and their siblings. The patients with the highest frequency of viral infection were younger and had the lowest rate of decline in lung function and severity score. We conclude that school-age patients with cystic fibrosis are no more susceptible to viral infections than their unaffected siblings. We were unable to demonstrate any significant adverse effect of respiratory viral infections on pulmonary function in 19 patients with cystic fibrosis aged 5 to 21 years.

Bowel obstruction following omental patching of aortic grafts.

Omental pedicle flaps are commonly interposed between aortic reconstructions and the nearby small bowel to prevent erosion, graft infection, and aortoenteric fistula. While the utility of this technique is intuitive rather than proven, it is easily performed and complications from this approach have rarely been reported. We report two patients in whom clinically significant intestinal herniation beneath such an omental pedicle flap occurred, necessitating relief of acute small bowel obstruction. A simple method of preventing this complication is proposed.

Multicenter two-dose trials of bivalent influenza A vaccines in asthmatic children aged six to 18 years.

Data from all of the vaccination centers that immunized asthmatic children six to 18 years old with bivalent influenza A/New Jersey/76 and A/Victoria/75 vaccines were analyzed. Systemic reaction indexes were somewhat higher in asthmatic children receiving the first dose of whole-virus vaccines than in similar vaccinees without asthma. Antibody levels after immunization, while different in some instances, did not show any significant trends toward either hypo- or hyperresponsiveness in the asthmatic children.

Prevalence of Mycoplasma hominis and Ureaplasma urealyticum (T strains) in urine of adolescents.

Adolescent children were surveyed for colonization with Mycoplasma hominis and Ureaplasma urealyticum by culturing urine specimens. Rates were compared between three study groups: (i) 397 children attending parochial schools, (ii) 293 children attending an adolescent clinic specializing in adjustment problems, and (iii) 86 children attending a renal clinic. The recovery rate was higher among postpubertal girls attending the renal clinic (33%) and the adolescent clinic (26%) than among students attending parochial high school (males 2%, females 8%). Girls had approximately eightfold higher rates than boys of the same age. Isolation of Mycoplasmataceae was associated with certain sociological determinants, such as dating, cigarette smoking, and coming from a broken home, but also with abnormal findings (protein, leucocytes) in urine.
