[Pharyngeal and anorectal gonorrhea. Incidence in Lausanne in 1981].

After a brief review of the literature on pharyngeal and anorectal gonorrhea, the authors report the incidence of this disease among 498 patients consulting for known or suspected venereal disease from January 1 to December 31 1981. 192 cases of gonorrhoea, of which 23 had extragenital localization, were treated with thiamphenicol (Urfamycine) in a single dose (2.5 g orally or 3 g in patients weighing over 80 kg). Of the 178 patients for whom follow-up was possible, recovery was obtained in 176 (98.9%). All the 23 patients with extragenital infection (7 with pharyngeal gonorrhoea and 16 with anorectal gonorrhoea) recovered completely. The efficacy of this treatment is discussed and compared with that of other antibiotics currently used in gonorrhea.
