[The sexual needs of homosexual HIV seropositive men].

A two-step study was conducted to identify the sexual needs of a group of seropositive homosexual men. At first, there was an interview with 30 men which aimed to define their objectives of sexual health. This was followed by a questionnaire distributed among 88 seropositive men and 173 seronegative men, who evaluated the objectives stated in the first step. The statistical analysis of collected data allowed for the identification and narrowing down of four major needs: being in good health, being in love, being sexual and, to a lesser degree, being secure. Results are discussed and point to the role played by the biological, psychological and sociological uneasiness in the context of the difficulties that seropositive homosexual men have in satisfying their sexual needs. This evaluation can prove useful in the planning and the implementation of sexological services for HIV-positive persons.

The role of laparoscopy in acute pelvic infections.

54 patients presented by history, physical examination and laboratory tests with suspected pelvic inflammatory disease (PID). The use of laparoscopy as a diagnostic tool proved in 13 cases (24%) that the presumptive diagnosis was incorrect. Bacteriological studies revealed chlamydial infection in 21 of 41 cases, in 6 cases only at laparoscopy in the pelvic cavity, gonococcal in 9 of 41 cases; mycoplasmas were identified in 15 cases, being the only pathogen in 7. In 9 cases, no recognized pathogens were isolated. Polymicrobism was frequent. Follow-up studies identified 5 cases of treatment failure; 2 of Gonococcus and 3 of Chlamydia, and detected 3 cases of Chlamydia which had not been identified initially. We discuss the use of laparoscopy in the diagnosis and for follow-up and treatment of PIDs.

Clindamycin with primaquine for Pneumocystis carinii pneumonia.

Combined therapy with clindamycin and primaquine was used in twenty-eight episodes of Pneumocystis carinii pneumonia in 25 patients, of whom 17 had been unresponsive or intolerant to conventional treatment and 8 were being treated for the first time. The treatment was effective in all but two episodes, the main adverse reaction being a generalised maculopapular rash.

Enzyme immunoassays and related procedures in diagnostic medical virology.

This review article describes several applications of the widely used enzyme immunoassay (EIA) procedure. EIA methods have been adapted to solve problems in diagnostic virology where sensitivity, specificity, or practicability is required. Concurrent developments in hybridoma and conjugation methods have increased significantly the use of these assays. A general overview of EIA methods is given together with typical examples of their use in diagnostic medical virology; attention is drawn to possible pitfalls. Recent advances in recombinant DNA technology have made it possible to produce highly specific nucleic acid probes that have a sensitivity approximately 100 times greater than that of EIA. Some applications of these probes are described. Although the non-labelled nucleic acid probes for use in the field are not as refined as non-labelled immunoassays, their range of applications is expected to expand rapidly in the near future.

Effect of aminoglycosides on the disposition of thyroid hormones and thyroglobulin.

Our study was designed to confirm the potential effects of three aminoglycosides on the disposition of thyroid hormones. Twenty-seven patients diagnosed with either cellulitis (n = 19), chronic osteitis (n = 4), or an abscess (n = 4) were selected. Thirteen patients received tobramycin, 60 to 100 mg iv q. 8 h., plus cloxacillin, 1 gm iv q. 4 h.; seven patients received netilmicin, 40 to 120 mg iv q. 8 h., plus cloxacillin, 1 gm iv q. 4 h.; and seven patients received either cloxacillin, 1.5 gm iv q. 4 h., or cefoperazone, 2 to 4 gm iv q. 12 h. for at least 7 days. Another group of six normal subjects received neomycin, 0.5 gm po q. 6 h. for 7 days. All these subjects had normal thyroid function before antibiotic dosing and none had thyroid function abnormalities. Tobramycin and cloxacillin/cefoperazone did not influence thyroid function. Netilmicin decreased the total serum concentrations of triiodothyronine (T3) from 114 +/- 9 to 75 +/- 7 ng/dl (P less than 0.01), probably because of increased clearance, as the T3 free fraction increased from 0.43% +/- 0.02% to 0.49% +/- 0.02% (P less than 0.05). Thyroxine (T4) and reverse T3 (rT3) levels were not affected. Neomycin decreased T3 levels from 104 +/- 8 to 92 +/- 7 ng/dl (P less than 0.05) and the serum concentrations of thyroglobulin from 17.3 +/- 2.0 to 11.7 +/- 2.0 ng/ml (P less than 0.001). Because T4 and rT3 levels did not change, our results suggest that neomycin may have directly affected the gland. We conclude that some aminoglycosides can alter the disposition of thyroid hormones.

Aztreonam: correlation between disk diffusion and agar plate dilutions susceptibility tests.

Regression lines and error rate-bounded analyses were performed for correlating inhibitory zone diameters with the 30-micrograms aztreonam disk and aztreonam minimal inhibitory concentration for gram-negative aerobic clinical isolates. A correlation coefficient of -0.81 was found for the regression line. Preliminary proposed criteria to distinguish susceptible isolates from resistant ones are: susceptible greater than or equal to 22 mm (MIC less than or equal to 8 micrograms/ml), intermediate 16-21 mm (MIC = 16 micrograms/ml) and resistant less than or equal to 15 mm (MIC greater than or equal to 32 micrograms/ml). Using these criteria, the rates for false-susceptible and false-resistant isolates were zero.

Detection of Epstein-Barr virus antigens and antibodies by peroxidase-labeled specific immunoglobulins.

Detection of the Epstein-Barr (EBV) antigens, early antigen (EA), viral capsid antigen (VCA), and nuclear antigen (EBNA) by the indirect immunoperoxidase technique was highly sensitive. Antibody titers to EBNA, EA, and VCA were determined in more than 25 sera of patients with Burkitt lymphoma (BL), nasopharyngeal carcinoma (NPC), or normal persons. A good correlation between the titers of these antigens was obtained by the immunoperoxidase and immunofluorescence methods. The indirect (anti-IgG) immunoperoxidase technique for the detection of EBNA is, in contrast to the indirect immunofluorescence method, highly sensitive. EBNA was associated with the chromosomes in cells arrested in the metaphase with colchicine.

[Effect of open heart surgery on the defense mechanisms against bacterial infections].

Extracorporeal circulation during open-heart surgery may damage cellular and humoral factors in the blood. Phagocytic functions of circulating polymorphonuclear leukocytes were investigated in 10 patients 1 day before, then 1 hour, 2, 4 and 10 days after open-heart surgery. Transient diminutions in the phagocytic capacity of polymorphs was found for Staphylococcus aureus and Escherichia coli in one patient, and E. coli only in two patients up to the 4th postsurgical day. A positive correlation was found between the duration of extracorporeal circulation and the transient diminutions in phagocytic capacity for these three patients. However, the bactericidal capacity of polymorphs and their capacity to reduce nitroblue tetrazolium were normal in all patients. The serum concentrations of total hemolytic complement, C3, IgG and IgM were generally diminished up to the 4th day after surgery, but the opsonic power of the serum was almost normal in all the patients.

[Selective deficiencies of phagocytosis and opsonization towards Staphylococcus aureus. 1. Preliminary study in normal humans and patients with debilitating diseases].

We studied simultaneously the bactericidal activity (BA) and the serum opsonic capacity (OC) towards S. aureus and Escherichia coli during 2 hours of phagocytosis in vitro. The PMNs and the sera from 17 seriously ill patients and from 10 normal individuals were tested. Both BA and OC towards E. coli were the same for all patients and controls. The BA for one patient and the OC for three other patients were found to be diminished significantly. The last three patients had infectious complications due to S. aureus only. The selective deficiency of OC towards S. aureus in these three patients may be connected with the pathogenesis of their infectious complications.
