[Uncomplicated acute male and female gonorrhea: treatment with a single oral dose of epicillin-probenecid].

We treated 142 patients with acute uncomplicated gonorrhea with a single oral dose of epiciline-probenecid. All cases were confirmed by culture on Thayer Martin medium at the first day and they were all laboratory tested seven days after treatment. At the control time the patients were asked about drug tolerance. All isolated strains were tested for beta-lactamase producing capacity and susceptibility to epiciline and penicillin. All patients who were culture positive seven days after treatment were considered to be treatment failures. The treatment was effective in 94.4% and we detected 8 Neisseria gonorrhoeae strains resistant to penicillin (5.6%); seven of these were PPNG strains. Tolerance to the drug was excellent in 90% of all cases; 9% presented minor adverse reactions for a short period of time. Therefore, the combination of epiciline-probenecid is a valid alternative for routine treatment of acute uncomplicated gonorrhea.

Genetical studies in nontraumatic retinal dialysis.

1. The retinal periphery was explored with binocular indirect ophthalmoscopy and scleral depression in members of the families of patients with detachment due to retinal disinsertions and 30 pedigrees have been thus obtained. 2. A genetic causation of this disease is postulated, based in the concentration of cases in some of the sibships studied (33% of the sibships with 2 or more siblings); furthermore, the disease was demonstrated in two identical twins and was absent in two fraternal twins. 3. The sex incidence was similar and the vast majority of affected individuals had normal parents, suggesting an autosomal recessive mode of inheritance for at least some of the cases.
