[Antibiotic prophylaxis with piperacillin in vaginal hysterectomy. Study of 1 dose versus 3 doses].

A homogeneous and consecutive series of 93 patients treated with vaginal hysterectomy is studied in a controlled, randomized clinical essay. The patients were divided in two groups. One of the groups received one single dose of 49 of piperacillin 30 minutes before surgery; the other, three doses of 4 g of the same antibiotic 30 minutes before surgery and 6 & 12 hours after it. No significant difference was found between both groups and therefore it is fair to suppose that one single preoperative dose of piperacillin shows similar efficacy to the usually used three doses, one preoperative and two postoperative.

The colposcopy and the cone biopsy in the diagnosis, treatment and follow-up of 81 cases of cervical intraepithelial neoplasia.

A conization was performed on 81 patients with histological diagnosis of cervical intraepitelial neoplasia (CIN), whom and previously a rigorous colposcopic examination. 64 patients were younger than 35 years. The previous strict colposcopic examination determined that in none of the cases were the surgical margins of the cone biopsy affected: In 26 cases there was no correlation between the previous biopsy and the histological diagnosis of the cone biopsy. The latter was--higher in degree in 9 cases and, in addition to this, in the 23 histerectomies that were performed after the conization, 7 surgical specimens showed CIN in their histological study. The non-involved surgical margins--that could be obtained in those cases with a careful previous colposcopy,--can not guarantee the exeresis of all the CIN zones. The biopsy of an atypical zone, in a colposcopic extensive lesion, cannot be representative of the whole lesion. In the follow-up--5 years maximum and 1 year minimum--3 relapses had appeared and 9 pregnancies had been diagnosed, that had not showed an increase in the number of premature labours, nor in the cesareas-rate.
