The Authors review the scientific literature on premenstrual syndrome (PMS), focusing on the diagnostic standards and the complex symptomatologic pattern. They report, furthermore, the results of a study of 4 groups of patients affected by PMS and treated with different therapeutic programs. The data obtained confirm that treatment of PMS must be personal and valued on the ground of dominant group of symptoms.

Three unrelated families with paracentric inversion of chromosome 15(q15q24) are reported. An additional pericentric inversion of chromosome 9 with breakpoints in p11.2q13 was also observed in one of the three families. Reproductive problems, such as stillbirths, spontaneous abortions and two live-born children with multiple abnormalities, were present.
Thyroid gland size was ultrasonographically determined in 35 pregnant women who live in an area with moderate iodine deficiency. Iodide salt was administered to group A (n = 17), whereas group B (n = 18) was used as a control. Each group was tested for thyroid-stimulating hormone serum levels, iodine excretion, and thyroid volume. In both groups thyroid-stimulating hormone levels were similar and did not change throughout pregnancy. The iodine excretion at the third trimester in the treated group was significantly (p less than 0.01) higher than that of group B (100.0 +/- 39.0 versus 50.0 +/- 37.0 micrograms iodine per 24 hours, respectively). Initially, thyroid volume did not differ between the two groups. At the end of pregnancy, no difference was found in thyroid size in group A, whereas in the untreated women it increased significantly (p less than 0.0001) with a mean increase of 1.6 +/- 0.6 ml (16.2% +/- 6.0%). These results show that the increased thyroid size in the control group was mainly a result of relative iodine deficiency and that iodoprophylaxis should be warranted even in areas with moderate iodine deficiency to prevent the increase in thyroid size and, probably, to avoid the risk of maternal and fetal hypothyroidism.
This study focuses on cervical cancer and the importance of establishing a suitable screening programme. The results of a study carried out in the Abruzzo region during a 10-year sample period are reported. A Population of 36,663 patients, of which 3,372 had never been screened, was included in the study. All patients were attending the Centre of Cytology and Colposcopy at the Clinic of Obstetrics and Gynecology in L'Aquila. In order to make progress in both the diagnosis and treatment of this pathology, it is necessary not only to obtain an interdisciplinary approach with constant cooperation between professional colleagues (cytologist, colposcopist and histologist), but also an increased sensitivity of the population to the need for screening.
Some authors suggested that MR imaging could represent an effective diagnostic alternative in the study of pathologic conditions of mother and fetus during pregnancy. To verify the actual role of MR imaging, we examined 20 patients in the 2nd and 3rd trimester of gestation, after a preliminary US examination. Fifteen patients presented fetal or placental pathologies; in 4 patients the onset of the pathologic condition occurred during pregnancy; in 1 case of US diagnosis of fetal ascites, MR findings were normal and the newborn was healthy. As for placental pathologies, our series included a case of placental cyst, two hematomas between placenta and uterine wall, and two cases of partial placenta previa. As for fetal malformations, we evaluated a case of omphalocele, one of Prune-Belly syndrome, a case of femoral asymmetry, one of thanatophoric dwarfism, a case of thoracopagus twins with cardiovascular abnormalities, two fetal hydrocephali, and three cases of pyelo-ureteral stenosis. As for maternal pathologies during pregnancy, we observed a case of subserous uterine fibromyoma, one of right hydronephrosis, one of protrusion of lumbar intervertebral disk, and a large ovarian cyst. In our experience, MR imaging exhibited high sensitivity and a large field of view, which were both useful in the investigation of the different conditions occurring during pregnancy. In the evaluation of fetal and placental abnormalities, especially during the 3rd trimester, the diagnostic yield of MR imaging suggested it as a complementary technique to US for the evaluation of fetal malformations and of intrauterine growth retardation.
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.
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.
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.
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.

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.
The association between contraception and Gardnerella vaginalis was studied in the population of L'Aquila. This research was conducted in the cytocolposcopic Center of the Obstetrics and Gynaecology Clinic, and the Department of Biotechnology and Biometry at L'Aquila University on 1212 females. Of the examined patients, 178 (14.7%) employed a prophylactic method and of these 104 (58.4%) used barrier-systems, while 74 (41.6%) used estroprogestins. Gardnerella vaginalis was isolated in 63 females (6.1%) that used no contraceptive and 19 (10.7%) that employed one.
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.
