[Histopathological correlation of biopsy of the endometrium between Novak's catheter and curettage]. / Correlación histopatológica de la biopsia de endometrio entre cánula de Novak y legrado biopsia.

It was accomplished a longitudinal retrospective and comparative study in the General Hospital Tacuba of the ISSSTE, From 1 July 1995 to the 30 of June of 1996, in order to determine the sensibility and specificity of the diagnosis obtained by means of Novak's cannula and the curettage, comparing them with the result obtained in the hysterectomy. From 194 hysterectomies performed in that period, 69 patient were excluded remaining 125 patient. We correlated the results from both methods with the results of the histological study of the uterus gotten by hysterectomy. It was found for the biopsy taken by Novak's cannula a specificity and sensibility of the 75% and for the curettage a sensibility of 63.26% and specificity of 65.30%, being a difference not meaningful for the sensibility as for the specificity between both methods (p > 0.01). Having a smaller mistake range when were tried to proliferative o secretor endometry, not thus when existed simple hyperplasia or with atypical endometrial hyperplasia. We concluded that both methods are equally useful for the study of the endometrial pathology.

[Pregnancy in adolescents. Complications, birth weight, somatometry of the newborn and Apgar score, comparison with the general population]. / Embarazo en adolescentes. Comparación de complicaciones, peso, somatometría y calificación de Apgar con la problación general.

The objective of this study was to compare pregnancy evolution, newborn's weight, its somatometry and Apgar's qualification of teenagers and the general population in a community where the socio-economic factor is similar among those two groups. Three hundred and two pregnancies in teenagers were analyzed, 69 of 12-15 years and 233 of 16-17 years at the time of pregnancy, against a control group of 304 pregnant patients of 18-39 years. It was a prospective, comparative, longitudinal study. Average age at the first delivery of the 606 patients was 18.1 years. There were no significant difference among the groups as to occupation. There was not significant difference among the three groups as to pre-natal control, weeks of gestation incidence of threatening abortion, toxemia, bleeding of the second half of pregnancy, premature rupture of membranes, proportion of deliveries and cesarean sections, as well as forceps application and newborns' sex. The most common indications of cesarean section in teenagers were CPD and acute fetal suffering, in the control group were CPD and pelvic presentation. There was significant difference comparing the weight, Apgar qualification at one minute and at three minutes in the 16-17 years group, and older of 18 years being greatest in the last group. There was significant difference in size, cephalic perimeter, thoracic perimeter and PC/pa ratio among the three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hysteroscopy in infertility]. / Histeroscopia en infertilidad.

An evaluation of hysteroscopy as complementary study of the sterile couple, was carried out; the hysteroscopic findings were compared with laparoscopic findings, and with Hysterosalpingography (HSG); it was a longitudinal, retrospective study of 20 patients. In the obstetrical antecedents there were 58 gestations, 50 of which ended in abortion. From de five normal cavities by HSG four were for hysteroscopy. As compared with hysteroscopy, HSG detected only 75% of submucous myomas, 85% of walls, 100% of IUD's fragments and of cervical incompetences. In the case of sinechias it was confirmed by hysteroscopy 80% of the diagnosed by HSG. The only case of endometrial polyp was detected by hysteroscopy. Surgical procedures were carried out in 40%, with complications in 16.6%. It was conclude that hysteroscopy is a complementary method, but necessary, in the study of the sterile couple with the possibility at the same time of being a therapeutic method.

[Abdominal pregnancy. Surgical emergency]. / Embarazo abdominal. Urgencia quirúrgica.

Concept, classification, frequency and predominant factors of abdominal pregnancy, were reviewed. The case of a patient 32 years old, from Hospital General Tacuba, ISSSTE; with a history of secondary sterility of seven years duration, win an abdominal pregnancy with symptomatology mainly digestive; she was under hypovolemic shock, acute abdomen, but with an ultrasonographic study showing intrauterine pregnancy and a tumor in right iliac fossa, which confounded the preoperative diagnosis. Exploratory laparotomy, was done. An alive product was found 14 to 16 years old, and living the placenta in situ. Evolutions was favorable. In the final comment the clinical picture, the diagnostic media, the management possibilities for the placenta and hemorrhage, are mentioned.
