[Peritoneal cyst. A case report].

Cystic mesothelioma is a rare benign tumor of the abdominal and pelvic peritoneum, consisting of solitary or multiple cysts. No more than 130 cases are reported. Several risk factors such as chronic peritoneal irritation, caused by foreign bodies, infection or endometriosis, were hypothesized but the pathogenesis is still unknown.

Artificial insemination with donor cryopreserved semen: importance of the volume of semen and influence of ovulatory dysfunctions.

The study deals with a program for artificial insemination by means of cryopreserved donor sperm, conducted at AIED (Italian Association for Demographic Education) in Rome from 1983 to 1986. Two groups of women, both having an average age of 30, and with an equal proportion of women with factors of reduced fertility, were inseminated with a different volume of cryopreserved sperm: a) 100 women were inseminated with an average number of 6.3 straws per cycle (total number of cycles 297) and 55 pregnancies were obtained (pregnancy rate = 0.

Ultrasound evaluation of the ovarian hyperstimulation syndrome.

282 cycles in 106 women going to be artificially inseminated at the AIED Center in Rome have been studied by means of ultrasound monitoring in order to evaluate the incidence of the ovarian hyperstimulation syndrome. In none of the patients, either in pharmacologically stimulated cycles (82 in 36 women) or in non stimulated cycles (200 in 70 women) moderate or severe hyperstimulation syndrome was reported. Only few mild cases occurred.
