Enlarged vestibular aqueduct in congenital non-syndromic sensorineural hearing loss in egypt.

To estimate the frequency of isolated enlarged vestibular aqueduct (EVA) in patients with non-syndromic sensorineural hearing loss (SNHL) in an Egyptian population sample and to correlate its size with the degree of hearing loss. The study group comprised 16 patients (32 ears) suffering from non-syndromic SNHL since childhood. After a complete basic audiological evaluation, all patients were submitted to non contrast CT scan of the petrous bone in both axial & coronal planes.

Laparoscopic, gynecographic and ultrasonographic vs. clinical evaluation of a pelvic mass.

One hundred fourteen patients with a clinically proven or suspected pelvic mass were subjected to pelvic examination and ultrasonography. Gynecography and laparoscopy were carried out in only 45 patients; those procedures were contraindicated in the other patients. The study showed that in patients with a large pelvic mass both clinical examination and ultrasonography had high diagnostic accuracy; therefore, the latter procedure does not seem to be necessary in the preoperative investigation of these patients.

Pelvic venous changes after tubal sterilization.

We studied pelvic venous patterns after tubal ligation and compared them after different tubal sterilization procedures. To this end transuterine pelvic venography was performed preoperatively and after the first and sixth periods postoperatively in 56 women. All procedures that interrupt or interfere with the blood supply were analyzed in terms of uterine congestion, uterovaginal and ovarian varicosities and the incidence of pelvic venous stasis.

Physiologic changes during CO2 and N2O pneumoperitoneum in diagnostic laparoscopy. A comparative study.

The aim of this work was to study the cardiovascular effects, the acid-base balance in serum electrolytes and chlorides in 50 patients during diagnostic laparoscopy, comparing the use of CO2 and N2O for pneumoperitoneum. The CO2 group showed a significant decrease in pH, a significant increase in pCO2 and a significant decrease in pO2, while the changes in HCO3 and base change were insignificant. In the N2O group, the changes in pH, pCO2, pO2, HCO 3 and base excess were statistically insignificant.

Comparative evaluation of laparoscopy and hysterosalpingography in infertile patients.

A comparative study of hysterosalpingography (HSG) and laparoscopy in the investigation of infertility is presented. From 1973-1977, 352 cases were investigated with both HSG and laparoscopy. In 57.
