[Fetal obstructive uropathies: prenatal diagnosis, prenatal and postnatal management]. / Uropatie ostruttive fetali: diagnosi prenatale, management pre e postnatale.

The urinary tract obstruction may depend by: ureteropelvic junction obstruction, vesicoureteric reflux, posterior urethral valves, megacystis-microcolon syndrome. Hydronephrosis accounts for 75% of prenatally diagnosed fetal renal abnormalities with, in many cases, renal dysplasia, oligohydramnios and Potter's sequence. With ultrasound is possible to diagnose most urinary tract obstructions that occurs in 1% of all pregnancy, but only 0.2% have clinical relevance. We have conceived an ultrasonographic protocol to evaluate the renal and urinary tract morphology, the cystis, the amniotic fluid and the external genitalia for a more easy ultrasonographic diagnosis and for the exact pre and postnatal management.

[Retrospective study of postoperative infectious morbidity following cesarean section]. / Studio retrospettivo della morbilità infettiva postoperatoria nel taglio cesareo.

The increase of cesarean sections produced more postoperative infections. Several authors assessed the effectiveness of chemioantibiotic prophylaxis to reduce the postoperative infective morbidity. Although the family of antibiotics more frequently used is that of cephalosporin, the best single agent has not been found yet. The aim of our study, made in the Department of Obstetrics and Gynecology of University of Naples "Federico II", is to propose a retrospective analysis concerning the incidence of cesarean section (CS), the postoperative infective morbidity and the employment of antibiotic prophylaxis. Our sample is a group of 13285 pregnant women, 3171 (23.9%) of these patients underwent to CS from 1st January 1985 to 31st December 1994. The group of 3171 women was divided in two subgroups, the first of 2748 patients un-derwent to antibiotic prophylaxis, the second of 423 was untreated due to their previous experience of allergy towards antibiotics or because there was no evidence of risk factors. The women we treated with antibiotics underwent a three days prophylactic therapy with cefazolin or ampicillin soon after the CS. The incidence of infective complications had a 21.2% rate over a total of 3171 women. Endometritis was the most common infectious complication following cesarean delivery. The rate was 53.3% in the case of primary cesarean section and 52.3% in the case of iterative cesarean section. The use of antibiotic prophylaxis gave us the opportunity to reduce the postoperative morbidity in the primary CS (23.4%) as well in the iterative CS (16.6%). On the contrary the untreated group had an infective incidence with a 33.8% rate in the case of primary CS and with a 27.4% rate in the case of iterative CS. Our opinion is that the administration of antibiotics as cefazolin and ampicillin is able to reduce in a significant way the incidence of postoperative infective morbidity as well the period of hospitalization.

Desogestrel versus gestodene in oral contraceptives: influence on the clinical and histomorphological features of benign breast disease.

Forty-four female volunteers asking for oral contraception, affected by symptomatic benign breast disease (BBD) were evaluated to compare the effects on mastalgia and breast nodularity of two different low dose oral contraceptives (OCs), containing 20 micrograms [corrected] ethinylestradiol + 150 micrograms desogestrel (EE+D) and 30 micrograms ethinylestradiol + 75 micrograms gestodene (EE+G), respectively. Physical examination, bilateral thermography, X-ray and/or ultrasonography of breast, and needle and screw-needle biopsies of mammary tissue were performed in all patients before OCs administration and after six cycles of treatment. OCs administration caused an overall improvement of mastalgia in 53%. Breast nodularity improved only in 8% of patients in both groups. Epithelial tissue modifications in mammary biopsies were observed, with involutive and/or secretory histomorphological and ultrastructural changes, frequently coexisting in different areas of the same breast.

PIP: In Italy, researchers compared data on 22 women who used the low-dose oral contraceptive (OC) containing 20 mcg ethinyl estradiol and 150 mcg desogestrel (EE+D) with data on 22 other women who used the low-dose OC containing 30 mcg ethinyl estradiol and 75 mcg gestodene (EE+G) to determine the pharmacological effects of the 2 OCs on women affected by mastalgia and breast nodularity. Clinicians performed physical exams, bilateral thermography, X-ray and/or ultrasonography of breast and needle and screw-needle biopsies of mammary tissue before OC administration and after 6 cycles of OC treatment. An overall improvement of mastalgia and breast nodularity occurred in 53% and 8% of all patients, respectively. There were no significant differences between groups. Among EE+D treated women, a marked secretory attitude in breast epithelial cells occurred, probably due to a prominent progestin effect. Both OCs increased the number of cytoplasmatic organules and intraluminal secretory material without any apparent increase of cell proliferation. The observed involutive and/or secretory histomorphological and ultrastructural changes often occurred in different areas of the same breast. These results suggest that low dose OC use by women affected by benign breast disease improves mastalgia but not breast nodularity.
