[Treatment of cervical intraepithelial neoplasia using the CO2 laser]. / Tratamiento de la neoplasia intraepitelial cervical con láser de CO2.

The use of laser therapy in CIN, is a practical method that has revolutionized the treatment of a very common pathology, that is the cervical neoplasia in its early stages. 86 patients with different stages of cervical intraepithelial neoplasia, were studied. Patients in groups I (45 patients) y II (28 patients), were submitted to a vaporization crater of the whole transformation zone because of having the cervical canal free of lesion. In group III (13 patients), a cylinder of the cervix was done to perform histological study, whether the cervical canal was compromised or not. The cytology control results for group I were excellent; from (45 patients) who came to 3-month check-up 79.1% of the whole presented negative II. For group II (28 patients), in first pap smear two patients (7.1%) had CIN, the rest of smears were reported 66% negative II, and in the 30.6% negative I. For the group III 14.2% (5 patients) of the whole had abnormal results, the rest of the smears 73.5% of the results reported negative II. The incidence of failure for this procedure is similar to that of hysterectomy with the same therapeutic goal .

[Clinical observation in the premature rupture of membranes. Early detection of maternofetal infections]. / Observación clínica en la ruptura prematura de membranas. Detección precoz de infecciones maternofetales.

One hundred patients with term pregnancy, were studied. There were placed in two groups of 50 each; one was the problem group with antecedents and confirmation of premature rupture of membranes; and the other group with intact amnios at the time of delivery, which served as controls. Clinical history, leukocyte count, temperature determination on admission and during trans-partum, leukocyte count in mixed blood from the umbilical cord and clinical surveillance were carried out, until 96 hours after delivery, of mother and child looking for sepsis signs. In the problem group there were 10 cases of maternal infection and 12 of newborns. There were no infections in the control group. There was no perinatal mortality. The most useful examination as to maternal and neonatal infection, was leukocytic count on admission, followed by trans-partum count and maternal temperature. Fetal leukocytic count above 12,500 per mm3 was useful in 70% of the newborns with complications.

Tubal sterilization and ovarian perfusion: selective arteriography in vivo and in vitro.

To determine whether there are changes in the utero-tubo-ovarian circulation after tubal sterilization, selective arteriograms were taken in vivo every 0.3--7.0 seconds with a Puck-type seriograph and also in vitro. A control arteriographic study was made. The operations performed were fimbriectomy and modified Pomeroy. The 30 patients studied were divided into two groups. One was formed by 20 nonpregnant women. The other ten patients were in the early puerperium. Arteriographic images with and without tubal sterilization were prepared, and the different techniques were compared. With the Pomeroy operations, the various tubal sites where surgery was performed were also compared. It was concluded that neither the modified Pomeroy sterilization nor fimbriectomy alters ovarian perfusion in either nonpregnant women or those in the early puerperium.
