"One-minute treatment" with thiamphenicol in 50,000 cases of gonorrhea: a 22-year study.

The results obtained with single-dose (2.5 g of thiamphenicol) therapy of gonorrhea in 50,000 patients are reported. Male patients included recent cases of acute or subacute urethritis and uncomplicated cases; all female patients had uncomplicated gonorrhea. Asymptomatic gonorrhea in both men and women was included in the therapy trial in all cases when "epidemiological" treatment was necessary. Tolerance of thiamphenicol was excellent; we observed only 62 cases of gastralgia or nausea and 12 cases of generalized pruritus reaction. No hematologic side effect was reported. The prescribed dose does not conceal incubating syphilis since 211 cases of recent syphilis were observed. Failures are reported year by year from 1961 to 1982 and, on the average, failure rates for men and women were 3.42% and 3.24%, respectively.

Prevalence of serum antibodies to herpes simplex virus types 1 and 2: application of an ELISA technique to 100 cases of anogenital herpes.

Sera of 100 patients affected by anogenital herpes were tested by an enzyme-linked immunosorbent assay (ELISA) technique using partially purified antigens obtained by extraction from the nuclei of infected Vero cells. Herpes simplex virus type 1 (HSV-1) was isolated from the anogenital lesions of 17 patients and herpes simplex virus type 2 (HSV-2) from 83 patients. The relative proportions of antibody of the IgG class to HSV-1 and HSV-2 were determined and their ratio (R) was calculated, except for 23 patients for whom the corrected optical density (COD) obtained for HSV-1 or HSV-2 antibody was less than the lower value limit of 0.025. A predominance of HSV-2 antibody (R less than 1) was found in 40 patients and was uniformly associated with isolation of HSV-2, whereas a predominance of HSV-1 antibody (R greater than 1) in 37 patients was found in the presence of infection with HSV-1 in 11 (30%) and with HSV-2 in 26 (70%) patients. This study also confirms the association of a higher frequency of recurrences with HSV-2: among the 55 patients with recurrent herpes, those from whom HSV-2 was isolated had a history of more recurrences than those infected with HSV-1 (P less than 0.05; Mann and Whitney's nonparametric test). No correlation between the number of recurrences and the level of HSV-2 antibody was found.

Genital human papillomavirus infections: correlation of cytological, colposcopic and histological features with viral types in women and their male partners.

To determine the incidence of anogenital papillomavirus infections and to assess the value of available diagnostic methods, we compared the cytological, colposcopic and histological features of anogenital papillomavirus-related lesions with their associated human papillomavirus types (HPV) in 300 women and in their male partners. HPV-type deoxyribonucleic acid was detected by blot hybridization in 398 out of 624 subclinical and clinically defined anogenital lesions. Whatever the site of the lesion, condylomas and low-grade intraepithelial neoplasia (IEN) were found in 84% of lesions associated with HPV 6-11, compared with 32% of lesions containing HPV 16-18 (P < 0.001). Among the HPV 16-18 associated lesions, high-grade cervical, vaginal, vulvar and anal intraepithelial neoplasias represented 45% (P < 0.001) of the lesions. In 65% of 23 cases of squamous anogenital cancer, HPV 16-18 and mixed types were present (P < 0.001). In 54% (161/300) of cases, the lesions were multicentric (161/300). On cytological examination, 27% of the samples gave false negative results. In cervical lesions, there was a good correlation between virological and colposcopic findings, but this was not true for extracervical mucous epithelia in the vagina or on the vulva. With peniscopy in the male partners 220 out of 410 had penile condylomatous lesions and more than half of the 350 male specimens examined by molecular hybridization contained HPV DNA. A correlation was found between the virus types in penile lesions or in cells of the distal urethra and in the cervical lesions of the sexual partner.(ABSTRACT TRUNCATED AT 250 WORDS)

[Bacteria isolated in 1994-1995 in female upper genitalia infections and in male urethritis. Distribution and sensitivity to antibiotics].

OBJECTIVE: Classify antibiotics according to their individual activity so as to identify those suitable for empiric therapy. METHODS: We studied bacterial strains isolated from patients with urethritis (n = 189) and upper genital tract infections (n = 163) between June 1994 and February 1995 in 3 hospital and 4 community laboratories. Upper genital tract infections were divided into two groups: proven infection on laparoscopy specimen (n = 79) and suspected infection with isolation of pathogen in cervical samples (n = 84). Pathogens isolated were: Chlamydia trachomatis in 36/12/15 cases respectively, Mycoplasma hominis in 12/20/13, Ureaplasma urealyticum in 55/30/15, Neisseria gonorrhoeae in 40/2/0, Haemophilus spp in 20/2/1, group B streptococci in 7/1/8, E. coli in 8/1/17 and miscellaneous in 11/8/15. The minimal inhibitory concentrations for all strains were determined in 4 laboratories for ofloxacin, erythromycin and doxycyclin against C. trachomatis, M. hominis and U. urealyticum, and for ofloxacin, erythromycin, doxycyclin, amoxicillin+clavulanate, cefotaxime and gentamicin against the other strains. The activity score (% susceptibility to each antibiotic weighted by the frequencies of each isolate in urethritis and upper genital tract infection based on recent French epidemiologic data) was calculated for each antibiotic. CONCLUSION: The antibiotics with the best empiric activity scores in urethritis were, in decreasing order: doxycyclin (90.4%), ofloxacin (88.1%), and erythromycin (50.2%). The most active combinations in upper genital tract infections were ofloxacin+amoxicillin (100%), doxycyclin+cefotaxime+metronidazole (95.9%) and doxycyclin+amoxicillin (95.3%).
