Postoperative pulmonary complications after gynecologic surgery.

OBJECTIVE: Investigate the frequency of, and risks for postoperative pulmonary complications after surgery for non-malignant gynecologic disorders. METHOD: A retrospective component included medical record data for one year. A prospective component enrolled 300 patients consecutively who were scheduled for gynecologic surgeries. RESULT: Postoperative pulmonary complications occurred in 1.22% of 328 open abdominal procedures in the retrospective study, and 2.16% of 232 in the prospective study. Pooling the data yielded a frequency estimate of 1.61%. Mean hospital length of stay (pooled data) increased 1.75 days in those with postoperative pulmonary complications. Smoking was the only significant risk factor (relative risk=3.9 using pooled data). CONCLUSION: Postoperative pulmonary complications after surgery for non-malignant gynecologic disorders are infrequent but increase hospital length of stay. Smokers are at increased risk.

National character does not reflect mean personality trait levels in 49 cultures.

Most people hold beliefs about personality characteristics typical of members of their own and others' cultures. These perceptions of national character may be generalizations from personal experience, stereotypes with a "kernel of truth," or inaccurate stereotypes. We obtained national character ratings of 3989 people from 49 cultures and compared them with the average personality scores of culture members assessed by observer ratings and self-reports. National character ratings were reliable but did not converge with assessed traits. Perceptions of national character thus appear to be unfounded stereotypes that may serve the function of maintaining a national identity.

Nucleic acid spot hybridization with nonradioactive labeled probes in screening for human papillomavirus DNA sequences.

We examined 161 human tissue samples using the spot hybridization technique with nonradioactive labeled DNA probes of human papillomavirus (HPV). Whole cells were spotted on nitrocellulose filters; DNA of the cells was denatured and fixed to the filter. Then the DNA spots were hybridized to nonradioactive labeled DNA and monitored by a sandwich immunoenzymatic reaction. This technique is simple, sensitive, specific, requires no special equipment, and can be used in clinical settings. HPV DNA was found in 92% of samples in which, on the basis of histologic and colposcopic criteria, its presence was suspected, as well as in 31 samples where it was not suspected.

[Current methods in the diagnosis of Chlamydia infections].

The pathogenicity of Chlamydia species is no longer questioned and most figures indicate that these organisms are the leading cause of sexually transmitted diseases. Diagnosis by direct examination of a stained slide is not acceptable due to inadequate sensitivity. The use of monoclonal antibodies conjugated to ITCF, however, is a good method to detect chlamydial particles. Cultures are made from specimens of heavily infected cells, centrifuged with cells from the McCoy cell line treated with cycloheximide. The inclusions are visualized using immunological techniques (immunofluorescence or staining with a peroxidase-antiperoxidase reaction). By using wells of microplates, this method is less expensive and can also be used for antimicrobial susceptibility testing. Serology (by MIF or ELISA) is very helpful, especially to investigate complications originating from a lower genital tract infection. Both techniques are useful in routine screening.
