Cirrhosis and pregnancy. A case report and review of the literature.

A clinical case of a pregnant suffering from hepatic cirrhosis with ascites, splenomegaly and portal hypertension is described. The pregnancy carried on till the 31st week, even though with the repeated use of tocholytic agents. Cesarean section was performed because of the onset of serious jaundice and the decline of general maternal conditions. The infant, who had an Apgar score of 8 at the 1st and 5th minute, died on the 10th day because of accuse haemorrhagic interstitial pneumonitis in premature lungs and hepatopathy associated with widespread jaundice. The mother was discharged on the 25th day of the postpartum period, in light of the net improvement of her general metabolic condition, the sudden regression of the jaundice and the decrease of the cholestasis indices. A review of the literature discussing maternal complications fetal risks, management of pregnancy and delivery and outcome of the newborn are presented.

Trazodone: a non-hormonal alternative for neurovegetative climacteric symptoms.

Hormone replacement therapy (HRT) is the treatment of choice for neurovegetative climacteric symptoms. In some women, however, HRT may either be contraindicated, or the patients themselves may prefer a non-hormonal form of treatment. Trazodone is a drug that acts a weak, but specific, inhibitor of the uptake of 3H-serotonin and is generally used for its antidepressant effects. In this study we have observed the efficacy of oral Trazodone (75 mg/day) in the treatment of the climacteric symptoms in 25 menopausal patients recruited at the Menopause Clinic of Ferrara University Hospital. The symptoms were scored from 0 to 3 according to presence and intensity. The patients were all complaining of climacteric neurovegetative symptoms (average symptom score 2.43). Symptoms scores were recorded before starting treatment and then again after 3 months. The appeared to be particularly effective on the intensity of anxiety (OR: 0.08, CI: 0-0.080), insomnia (OR: 0.15, CI: 0.02-0.71), and irritability (OR: 0.29, CI: 0.04-1.48). The intensity of hot flushes appeared reduced but was not statistically significant (OR: 0.52, CI: 0.08-1.87). However, the average total score of symptoms appearing in the Kupperman scale was reduced (-14%) after treatment. Trazodone should be kept in mind as a possible alternative to HRT. This drug can be particularly useful for those patients whose climacteric symptoms have a marked connotation of anxiety rather than for hot flushes or when HRT are contraindicated.

The menopausal transition: a dynamic approach to the pathogenesis of neurovegetative complaints.

In our cross-sectional study we investigated the separate influence of three main factors, namely menopausal and estrogen status, and chronological age, on ten neurovegetative climacteric complaints reported in the scale of Kupperman et al. A multivariate statistical analysis was performed by a multivariate statistical approach on 1161 untreated women seen at the Menopause Center of the Ferrara University Hospital. Ninety women (age range, 41-54 years) were premenopausal; 492 women (age range, 38-55 years) were perimenopausal with irregular periods or amenorrhea for less than 12 months; 468 women (age range, 41-69 years) had a spontaneous menopause (age range, 37-66 years); 111 had had hysterectomy with bilateral ovariectomy while still regularly menstruating. Serum estrone was used as the indicator of the patients' estrogen status. A clear positive trend was demonstrated between menopausal status and the prevalence of depression, hot flushes, insomnia and joint pain. However, only the prevalence of hot flushes amongst these four symptoms was significantly related with the climacteric estrogen decline (beta = -0.006, P = 0.001). Moreover, menopausal status appeared to influence the intensity of fatigue, hot flushes, insomnia and paresthesia. Age was found to significantly (P = 0.053) co-vary only with the intensity of the hot flushes, with a positive relation (beta = 0.092, r = 0.104, P = 0.003), whereas estrone values did not significantly co-vary with any symptom. Furthermore, while neurovegetative symptoms are largely present also in the absence of hot flushes, when these latter are present, they exacerbate both the intensity and the prevalence of all the other symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

Haematocervix during hormonal replacement therapy.

A postmenopausal woman, receiving cyclic hormonal therapy, presented to our clinic with acute pelvic pain, absence of withdrawal bleeding and clinical signs of vagal stimulation (nausea and vomiting). Vaginal exploration and ultrasonographic imaging accounted for haematocervix, which was confirmed by surgical blood evacuation.

Influence of spontaneous and surgical menopause on atherogenic metabolic risk.

We evaluated serum total-, LDL-, HDL-, cholesterol and triglycerides in 858 women. Sixty-seven were in premenopause, 307 in perimenopause, 326 in spontaneous menopause, and 158 women underwent hysterectomy. Of these, 101 had bilateral ovariectomy, 24 with unilateral ovariectomy and 33 with retention of both ovaries. After correcting for chronological age and body mass index by variance analysis, it was found that total-, LDL- and HDL-cholesterol significantly increased during menopause without changes in the total cholesterol/HDL-cholesterol, LDL-cholesterol/HDL-cholesterol and triglycerides/HDL-cholesterol ratio. The changes gradually occurred during the months preceding spontaneous cessation of menses. Atherogenic metabolic risk (as relative risk of high total and LDL-cholesterol, estimated by logistic regression analysis) significantly increased in all groups of women in reference to premenopause. The risk observed in surgical menopause with bilateral ovariectomy was higher than in spontaneous menopause, and conservation of ovaries in hysterectomized women seems to protect only partially against such an increase.

Influence of oral contraceptives on fasting gallbladder volume.

A total of 615 healthy fertile women (518 pill users and 97 non-users) were examined by real-time ultrasonography for fasting gallbladder volume, gallstones and biliary dysmorphism. None of the six examined combinations of oral contraceptives appeared to influence fasting gallbladder volume significantly. When fasting gallbladder volumes were reanalyzed according to the presence or absence of recognized biliary risk factors, significant modifications were detected, in both pill users and non-users. These changes related only to age and parity. Relative risks of cholelithiasis and biliary dysmorphism were not affected by contraceptive treatment.

Risk factors in vulvar carcinoma recurrences.

18 patients with invasive vulvar carcinoma treated by radical vulvectomy and bilateral groin lymphadenectomy have been evaluated. An 18% of local and 22% of pelvic or distant recurrences occurred. The local recurrences had favorable prognosis, whereas the pelvic or distant recurrences a worse prognosis. The staging, the tumour size, the nodes involvement, the stromal infiltration and the lymphoplasmacytic infiltration, as prognostic factors, have been evaluated. All these factors, except the tumour size, influenced the pelvic or distant recurrences. The pelvic or distant recurrences were contemporaneously associated with mild phlogistic infiltration and depth of invasion > 5 mm.

Combined use of progesterone challenge test and endometrium thickness evaluated by transvaginal ultrasonography in the preventive management of postmenopausal women.

Endometrial thickness was evaluated in apparently normal postmenopausal women by transvaginal ultrasonography and the results were compared with the response to the progesterone challenge test (PCT). A positive correlation between amount of withdrawal bleeding after PCT and endometrial thickness was found, also demonstrated by the significative correlation between bleeding length and endometrial thickness. Among women referring withdrawal bleeding, 100 and 22% of cases classified as overt flow and spotting, respectively, were characterized by pathologic histological findings. The combined use of these two procedures is suggested as an effective screening mean in the preventive endometrial management of apparently normal postmenopausal women to select candidates for diagnostic invasive procedures.

Betamethasone-induced lecithin release in vitro from the fetal membranes.

Lecithin release from fetal membranes and placental tissue was assayed in basal conditions as well as under betamethasone administration. In the absence of the steroid, amnion and chorion released lecithin as a function of incubation time. Both tissues responded to betamethasone by increasing the lecithin release, the amnion exhibited a higher basal level and a greater responsiveness to the hormone than the chorion. Basal lecithin release from placental tissue was unaffected by any steroid concentration.

Evaluation of bone metabolic markers as indicators of osteopenia in climacteric women.

Lumbar bone mass (LBM) determination by quantitative computerized tomography in pre-, peri- and postmenopausal women was utilized to identify subjects at risk to develop osteoporosis. The results were related to determinations of bone metabolic markers (serum osteocalcin and urinary calcium excretion). Osteocalcin was the only metabolic marker which underwent significative changes. However, we found very poor correlations between LBM and metabolic markers and it is concluded that bone mass determination remains the method of choice to select women for preventive therapy.

Surgical treatment of invasive carcinoma of the vulva. A reappraisal.

The Authors studied three groups of patients affected by invasive vulvar carcinoma. The first group (19 cases), treated by radical vulvectomy and bilateral inguinal lymphadenectomy, had a survival rate at 5 years of 89% in Stage I and 56% in Stage II. The second group (9 cases) which presented poor general health conditions, had a survival rate at 4 years of 33% and 14% in Stage I and in Stage II, respectively. The third group of patients (7 cases), who refused any type of treatment, died within 12 months. Nodal involvement influenced survival rate. In fact, regardless of the stage, a survival rate at 5 years of 92% and 26% was seen in patients with negative nodes and positive nodes, respectively. In conclusion, the study confirms that radical surgery is the therapy of choice in advanced carcinoma of the vulva. However, early diagnosis remains the most important agent in reducing the extension of the surgical treatment.

Influence of estrogens on serum free fatty acid levels in women.

A relationship between plasma levels of FFA and incidence of hormone-dependent breast cancer has been suggested. This observation has drawn our attention to possible complementary actions of ovarian steroids on circulating FFA levels. Measurements taken in normal women during the menstrual cycle and in ovariectomized women with and without estrogen replacement therapy demonstrate that 1) levels of FFA present in serum are lower during the luteal phase than during the follicular phase; 2) levels of FFA are significantly higher after ovariectomy; and 3) these are again reduced by substitutive estrogen therapy.

Modification of number and of affinity of endometrial EGF receptors during the menstrual cycle.

We have analysed the distribution and the binding properties of the epidermal growth factor (EGF) receptor in human endometrium during the menstrual cycle to validate the proposal that steroids affect the growth rate of target cells via growth factor-related pathways. The total number of EGF receptors and their affinity for the iodinate exogenous ligand are significantly higher during the proliferative than the secretory phase; the binding kinetics appear to be hyperbolic and sigmoid during the proliferative and the secretory phase, respectively. These results suggest that endogenous sex steroids can regulate the levels and the properties of EGF receptors in vivo, and support the possibility that receptor-coupled events may play a role in estrogen-stimulated growth.

Studies on amniotic prolactin: chromatographic pattern and correlation with the lecithin content.

We have measured the concentrations of prolactin and lecithin in the amniotic fluid from 20 normal pregnant women in the 2nd and 3rd trimester. Prolactin is present totally as a low-molecular-weight form, 'little' prolactin, and appears to correlate negatively with lecithin during the 2nd and positively during the 3rd trimester. On the basis of these results and of the information that prolactin is present as high-molecular-weight isohormones in maternal blood, it is argued that amniotic prolactin is synthesized 'in situ' and that different mechanisms are involved in the regulation of prolactin production.

Ovarian steroids modulate the action of calcitonin in women.

Slow i.v. infusion of salmon calcitonin into normal women led to a transient increase in plasma concentrations of cyclic AMP and to a decrease in plasma calcium, which was maintained for at least 2 h. These responses were significantly reduced in the same patients after hysterectomy and ovariectomy. In contrast, maintenance of the ovaries at the time of surgery, or substitutive hormonal therapy, seemed to restore the sensitivity to exogenous calcitonin, suggesting a permissive role of ovarian steroids in the effect of calcitonin. The most likely explanation for this phenomenon is that these hormones influence either the number of calcitonin receptors or the coupling of the receptors to the functional unit of bone adenylate cyclase.

Regulation of endometrial transglutaminase activity during the menstrual cycle.

When human endometrial transglutaminase was measured a 10-fold higher activity was detected during the secretive phase. This change was not related to either differences in solubility of the enzyme or to selective contamination by plasma factor XIII and rather appears to depend on the expression of the tissue form of transglutaminase, suggesting that this enzyme is regulated in vivo by progesterone.

Effect of the hormonal contraception on serum reverse triiodothyronine levels.

Thyroid hormones and the thyroxine-binding globulin are increased during hormonal treatment with oral contraceptives without changes in the thyroidal economy. Now we report that even reverse triiodothyronine, the main peripheral catabolite of thyroxine, is significantly increased during therapy with oral contraceptives.

Prolactinemia during the menstrual cycle. A possible role for prolactin in the regulation of ovarian function.

We measured the concentration of circulating prolactin (PRL) in the serum during ovulatory and anovulatory cycles of normoprolactinemic menstruating women. The results demonstrate that during the luteal phase of ovulatory cycles a significant increase of PRL is observed together with that of progesterone. On the contrary, in menstruating women with anovulatory cycles we could not detect these increases. These data, analyzed together with the concomitant changes of gonadotrophins secretion, suggest a possible luteotrophic action of PRL in humans during the menstrual cycle.
