[New concepts in the induction of ovulation. A logarithmic assessment of estradiol production during controlled ovarian hyperstimulation for fertilization in vitro]. / Nuevos conceptos en inducción de la ovulación. Una evaluación logarítmica de la producción de estradiol durante la hiperestimulación ovárica controlada para fertilización in vitro.

The objective was to evaluate the exponential response of serum estradiol to controlled ovarian hyperstimulation (COH) in an in vitro fertilization-embryo transfer (IVF-ET) program through measurement of logarithm of serum estradiol area under the curve (LOG-OUC). One hundred three patients undergone conventional IVF-ET with pituitary suppression were studied. For to calculate the LOG-AUC estradiol, trapezoidal formula and ten-fold logarithm definitions were employed. The estradiol synthesis have notorious logarithmic changes during all COH. There was significant difference between estradiol AUC for initial and final phases of controlled ovarian hyperstimulation. As conclusion LOG-AUC of estradiol can be used for to evaluate the ovarian response to superovulation, its prognostic value for following IVF-ET intent is discussed.

[Clinical evaluation of patients submitted to open vs conventional gynecologic laparoscopy]. / Evaluación clínica de pacientes sometidas a laparoscopia ginecológica con técnica abierta versus laparoscopia convencional.

The objective was to comparate the clinical evolution and rates of complications for open and conventional gynecological laparoscopy. Were studied the cases of 253 patients divided in two groups: Group 1 (n = 106) patients treated with open laparoscopy, and group 2 (n = 147) patients managed with conventional surgery. The major indication for performing laparoscopy was infertility management. There were not early or I ate complications of trocar insertion or operative laparoscopy in the group 1. However, in group 2 there were four complications (P < 0.05), two related with needle or trocar insertion. As conclusion, in the studied group open laparoscopy can to eliminate the risks of blind insufflation and trocar insertion observed in the classifical technique, is a safe and efficacious method to treat several gynecological pathologies.

[Clinical evaluation of patients treated with open gynecologic laparoscopy]. / "Evaluación clínica de pacientes sometidas a laparoscopia ginecológica con técnica abierta".

The objective was to evaluate the clinical evolution and rates of complications for open gynecological laparoscopy. Were studied the records of ninety two patients treated with open laparoscopy for gynecological pathology. The major indication for performing laparoscopy was infertility management. There were not early or late complications of trocar insertion or operative laparoscopy. As conclusion, in the studied group open laparoscopy can to eliminate the risks of blind insufflation and trocar insertion observed in the classical technique, is a safe and efficacious method to treat several gynecological pathologies.

Infección por Helicobacter pylori en niños sin dispepsia en Curundú y Parque Lefevre / Helicobacter pylori infection in children without dyspepsia in Curundu and Parque Lefevre

A study of seroprevalence of Helicobacter pylori determined by ELISA IgG, was conducted in 83 consecutive healthy children. The majority of the children (55%) had the bacterium. Seropositivity was demonstrated in 55% of the age group 0-5 years old, in 47% of 6-10, and in 67%, of the group 11 to 15. Of the children without sanitary inside their homes 86% were seropositive, versus 47% of the children with sanitary in their homes
