[Vulvar lesions caused by Papillomavirus (HPV): effectiveness of thymopentin (Syntomoduline). First results and experiences]

The study included two different sized groups of patients suffering from various degrees of valvular microcondylomatosis. A group of 40 patients was treated using combined therapy while a second group of 20 patients received immunomodulating therapy alone with Sintomodulin. In particular, possible changes in the T-cell line of the immune system and correlations between the viral lesion and variations in serum levels of lymphocyte subpopulations were assessed. Results were analysed up to one year after the end of therapy.

[Indications and contraindications for normal labor in patients who previously underwent cesarean section]

In line with previously published data from all over the world, the Authors are in favour of vaginal delivery as a valid and safe alternative in women who have had a previous cesarian section, provided they are selected following appropriate screening protocol, as described in this paper. A retrospective study was performed to analyse data over a 10-year period in the Department of Ostetrics and Gynecology of the University of Aquila: of 1253 selected patients, 674 (54%) had a normal vaginal delivery, whereas 577 (46%) had a repeat cesarian section following the onset of fetal distress; no case of uterine scar rupture was recorded.

[Validity of psychoprophylaxis in obstetrics. Authors' experience]

The Authors report the results based on 20 years of practice on obstetric psycho-prophylaxis (PPO). Data on presence at course, on frequency, on primipares/pluripares ratio, on labour, on timing and mode of delivery, are assembled. Moreover, neonatal status at birth and at 10th day of life, are investigated. The data obtained were compared with a control group, constituted by women without any treatment before delivery. The acquired experience confirm the utility of PPO in the ordinary clinical practice.

[Continuous peridural analgesia-anesthesia during labor. Experiences and considerations]

Fifty pregnant women attending the Obstetrics Department of the University of Aquila were included in the study. Patients were matched for age, weight, height, parity, Bishop index, temperature, arterial pressure, and cardiotopography. Twenty-five patients were assigned to the control group, the remaining twenty-five received peridural analgo-anesthesia during labour and birth so as to create a continuous lumbar epidural block. The results confirmed that this method of anesthesia is an aid against psycho-physical stress and pain in pregnant women.

Ultrastructure of fetal human gonad before sexual differentiation and during early testicular and ovarian development

The development of the human gonad was investigated by light and transmission electron microscopy in 20 embryos and fetuses between 4.5 and 11.5 weeks of gestation, i.e. during the stages of sex-indifferent gonad, initial testicular and ovarian development. The gonadal blastema in 4.5-week-old embryos appeared formed by poorly differentiated somatic mesothelial cells, and by specialized germ cells (PGCs) with signs of ameboidism, cellular structures suggesting active protein biosynthesis and mitotic activity. The sexual differentiation of the gonads was clearly observed in 7-week-old embryos and involved at the same time the testis and the ovary. The former contained seminiferous cords formed by palisades of poorly differentiated Sertoli cells, which were segregated from the mesothelium by a rudimentary albuginea. The interstitial tissue at this age contained mesenchymal cells. Between 8 and 11.5 weeks of gestation, there was a synchronous cytodifferentiation of both Sertoli and Leydig cells. The latter acquired features of steroidogenic elements. The ovaries of 7-week-old fetuses contained packed ovigerous cords formed by somatic and germ cells (oogonia). The former embraced the oogonia with thin overlapping cytoplasm projections, and acquired features similar to those of cells in primary follicles, already at this early fetal age. At the same time the sexual differentiation of the gonads involved somatic and germ cells. In the female, the oogonia continued to show the main features they had during migration and colonization, including a high mitotic rate, signs of ameboidism and a developed apparatus for protein synthesis. On the contrary Gonocytes enclosed in the seminiferous cords progressively entered a quiescent phase characterized by a reduced mitotic rate, a decrease of endoplasmic reticulum and nucleolar complexity. The chronological relationship between the cytodifferentiation of Sertoli and Leydig cells, and changes of germ cells, suggest that somatic components of the testis may contribute to a male type of differentiation of germ cells from the very beginning of sexual differentiation.

Prevalence of non-specific vaginitis and correlation with isolation of Gardnerella vaginalis in Italian outpatients

Among all subjects attending a Center for prevention of female genital tract cancer Gardnerella vaginalis was isolated from 57 out of 171 women affected by non-specific vaginitis (NSV), from 15 of 703 non-NSV vaginitis patients and from 10 of 338 healthy adults. Postmenopausal women showed an increased rate of asymptomatic carriage of G. vaginalis. The data suggest a relatively weak association between clinical diagnosis of NSV and isolation of G. vaginalis.

[Cervical maturation. Physiologic aspects and pharmacologic implications]

The latest theories on cervical maturation and the techniques of pharmacological induction of labour are summarised. The role of the prostaglandins is particularly stressed both from the physiological viewpoint and as drugs of choice for effective pharmacological induction of uterine cervix. Finally, the personal clinical protocol for the induction and management of labour is reviewed.

Pericentric inversion of chromosome 19 in three families

Pericentric inversion of chromosome 19 has been found in several members of three unrelated families from a restricted geographical region. In one of the families, an additional pericentric inversion of chromosome 9 was observed. Reproductive problems, multiple abortions in two families and a neonatal death in the third, were present. A review of previously described cases is included, and the genetic risk connected with this type of rearrangement is also discussed.

Familial paracentric inversion of chromosome 15 (q15q24)

A paracentric inversion of chromosome 15 was observed in the father of two infants who died 29 days and 24 hours, respectively, after birth. The same inversion was found in two sisters of the proband.

[Evaluation of gestational age by comparing ecographic results with amniotic cell morphology]

The Authors compared the foetal growth, evaluated by using echographic technique, and the study of amniotic cells morphology, following the Philippe's classification. The results obtained show a good correlation between the two methods.
