[Comparative study of cryosurgery and hysterectomy in the treatment of cervical intraepithelial neoplasia]. / Estudio comparativo de criocirugía e histerectomía en el tratamiento de la neoplasia intraepitelial cervical (NIC).

The purpose of this study was to compare the results of conservative management with cryosurgery and with hysterectomy in different stages of NIC. The records of 235 treated patients from 1984 to 1991, were reviewed; 140 patients were treated with cryosurgery and 95 with total hysterectomy. Cure rate was for stage I in 34 patients (94.5); for stage II in 54 patients (98.2%), and for stage III in 46 patients (93.9%). For hysterectomy in NIC I in 5 patients (100%); for NIC II in 15 (100%), and for NIC III in 74 (98.66%). Statistical study with square Chi showed a not significant P which means that there is no difference in the results of Cure and No Cure in both procedures. It is concluded that intraepithelial cervical neoplasia may be managed with both procedures, provided that the established criteria for cryosurgery and hysterectomy, are followed.

[The treatment of cervical human papillomavirus (HPV) infection with trichloroacetic acid]. / Tratamiento de la infección cervical por el virus del papiloma humano (VPH) con ácido tricloroacético.

Ever since the alterations caused by the HPV on the cervix were discovered, countless treatments have been employed but the ideal method still remains unknown. The objective of the experiment was to assess the efficiency of handling the cervical infection caused by the HPV, by means of trichloroacetic acid, 85% rate. During the period comprised between April 1989 and March 1990, 60 patients were subject to close analysis. The general diagnosis drawn cytology, colposcopy, and histopathology was cervical condyloma, lacking any collateral evidence of intraepithelial cervical neoplasia. The treatment consisted of 3 weekly applications of trichloroacetic acid at 85% rate directly upon the cervix. They were all assessed through cytology and colposcopy every 3 months, during a year's period. After the first 3 months, a 73.4% healing rate was observed, which decreased to 68% after 6 months and to a 65% after 9 months; this last healing rate remained unchanged after 12 months. Pregnant patients showed higher healing rates. We have drawn the conclusions that the trichloroacetic acid is an efficient agent to treat the referred injuries, and it offers as well the advantages of low costs, no secondary effects and an easy application and handling.
