Effects of ipriflavone administration on bone mass and metabolism in ovariectomized women.

The aim of the present study was to assess the effects of ipriflavone administration in the prevention of the rapid bone loss that follows ovariectomy in women. After 10-30 days from bilateral ovariectomy, patients received either the sole calcium supplementation (500 mg/day, n = 16) or ipriflavone (600 mg/day, n = 16) in addition to the same daily calcium supplement for 12 months. In calcium-treated subjects urinary hydroxyproline excretion, serum alkaline phosphatase and plasma bone Gla protein levels showed a substantial (p < 0.01) increase, while radial bone density significantly (p < 0.01) decreased 6 months after surgery. In ipriflavone treated group the patterns of biochemical markers indicated that ipriflavone can restrain the bone remodeling processes and radial bone density showed no significant modification during the 12 month study period. These results demonstrate that ipriflavone administration prevents the rapid bone loss that follows ovariectomy. Thus, ipriflavone can represent an attractive alternative for the prevention of osteoporosis in postmenopausal women who present contraindications to the estrogen replacement therapy.

The association of ultrasonography and CA-125 test in the preoperative evaluation of ovarian carcinoma.

The aim of this study was to verify the role of the association of pelvic ultrasonography and CA-125 assay in the preoperative evaluation of ovarian carcinoma. The Authors examined 119 patients undergoing laparotomy for adnexal masses. Thirty-six had an ovarian carcinoma, the other 83 patients were affected by benign ovarian pathologies. Before surgery every patient underwent a pelvic ultrasonography. The data resulting from ultrasonography were processed on the basis of a personal scoring morphologic echostructural evaluation system. Furthermore in every patient the preoperative serum levels of CA-125 were measured. In the group of patients with ovarian carcinoma the ultrasonography score was greater than or equal to 10 in 26, while serum CA-125 was greater than or equal to 65 U/ml in 30 and greater than or equal to 35 U/ml in 31. In the group of patients with benign ovarian pathology the ultrasonography score was found to be greater than or equal to 10 in 2, while serum CA-125 was greater than or equal to 65 U/ml in 4 and greater than or equal to 35 U/ml in 20. Fixing 10 as reference value of ultrasonography score for ovarian carcinoma diagnosis, pelvic ultrasonography and a sensitivity of 72.2%, a specificity of 97.9%, a diagnostic accuracy of 89.9%. With a reference value of 65 U/ml CA-125 had a sensitivity of 83.3%, a specificity of 95.2%, a diagnostic accuracy of 91.9%. With a reference value of 35 U/ml CA-125 had a sensitivity of 86.1%, a specificity of 75.9%, a diagnostic accuracy of 79.0%.(ABSTRACT TRUNCATED AT 250 WORDS)

Sjögren's syndrome: clinical, cytological, histological and colposcopic aspects in women.

Sjögren's syndrome, characterized by a progressive alteration of the exocrine glands which ultimately results in their atrophy, has the highest incidence among females. The main etiopathogenetic mechanism is autoimmunological. The symptomatology is made up of symptoms depending on an altered glandular secretion and mucosal dryness. Dyspareunia and pruritus, due to vaginal and vulvar dryness, are quite common symptoms. Few studies have considered the clinical and histological consequences of Sjögren's syndrome in the external female genitalia. In the present study 26 women (mean age 46 years) affected by Sjögren's syndrome were examined by means of a series of tests including gynecological examination exam, colposcopic inspection and cervical biopsy. All the patients showed a particular dryness a series of tests including gynecological examination failed to evidence malign cells and, in 15% of the subjects, showed an estrogenic insufficiency in various degrees. The colposcopic inspection revealed dystrophic processes resulting in the atrophy of the cervico-vaginal mucosa in 50% of the cases. The histological findings of the cervical biopsies evidenced the presence of a chronic cervicitis in 10% of the cases.

Placental transfer of pinazepam and its metabolite N-desmethyldiazepam in women at term.

Placental transfer of pinazepam and its metabolite N-desmethyldiazepam was investigated in 25 pregnant women at term. Pinazepam was administered orally as a single (10 mg) dose to 13 women, or in multiple doses of 5 mg daily to 12 women. The dose-delivery interval ranged between 1 and 26 h for the single dose, and the period between the last of the multiple doses and delivery was 1.4 to 24 h. Pinazepam and N-desmethyldiazepam were measured in plasma obtained from the umbilical vein and from the mother, at delivery. Pinazepam was only detectable in plasma after the 10 mg dose. The drug did not reach an apparent equilibrium between fetal and maternal plasma. The average (+/- SEM) cord/maternal ratio of plasma pinazepam concentrations was 0.64 +/- 0.07. N-desmethyldiazepam was detectable on each occasion. Its concentration in the plasma from the cord vein became higher than that in the maternal specimens 1-2 h after administration of the parent drug. Little N-desmethyldiazepam was excreted in breast milk.
