RESUMO

OBJECTIVE: To describe the clinical and ultrasound characteristics of recurrent granulosa cell and Sertoli-Leydig cell tumors. METHODS: This was a retrospective observational study performed at Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS, Rome (Gemelli center), Italy. Patients with a histological diagnosis of recurrent granulosa cell tumor or Sertoli-Leydig cell tumor were identified from the database of the Department of Gynecological Oncology. Those who had undergone a preoperative ultrasound examination at the Gemelli center between 2012 and 2020 were included, and the data retrieved from the original ultrasound reports. In all of these reports, the recurrent tumors were described using International Ovarian Tumor Analysis (IOTA) terminology. If a patient had more than one episode of relapse, information from all episodes was collected. If there was more than one recurrent tumor at the same ultrasound examination, all tumors were included. One expert sonographer also reviewed all available ultrasound images to identify typical ultrasound patterns using pattern recognition. RESULTS: We identified 30 patients with a histological diagnosis of recurrent granulosa cell tumor (25 patients, 55 tumors) or Sertoli-Leydig cell tumor (five patients, seven tumors). All 30 had undergone at least one preoperative ultrasound examination at the Gemelli center and were included. These women had a total of 66 episodes of relapse, of which a preoperative ultrasound examination had been performed at the Gemelli center in 34, revealing 62 recurrent lesions: one in 22/34 (64.7%) episodes of relapse, two in 4/34 (11.8%) episodes and three or more in 8/34 (23.5%) episodes. Most recurrent granulosa cell tumors (38/55, 69.1%) and recurrent Sertoli-Leydig tumors (6/7, 85.7%) were classified as solid or multilocular-solid tumors, while 8/55 (14.5%) recurrent granulosa cell tumors and 1/7 (14.3%) recurrent Sertoli-Leydig cell tumors were unilocular cysts and 9/55 (16.4%) recurrent granulosa cell tumors were multilocular cysts. The nine unilocular cysts had contents that were anechoic (n = 2) or had low-level echogenicity (n = 7), had either smooth (n = 4) or irregular (n = 5) internal cyst walls, and ranged in largest diameter from 8 to 38 mm, with three being < 20 mm and five being 20-30 mm. On retrospective review of the images, two typical ultrasound patterns were described: small solid tumor measuring < 2 cm (15/62, 24.2%) and tumor with vascularized echogenic ground-glass-like content (12/62, 19.4%). CONCLUSIONS: Some granulosa cell and Sertoli-Leydig cell recurrences manifest one of two typical ultrasound patterns, while some appear as unilocular cysts. These are usually classified as benign, but in patients being followed up for a granulosa cell tumor or Sertoli-Leydig cell tumor, a unilocular cyst should be considered suspicious of recurrence. © 2023 The Authors.

RESUMO

OBJECTIVE: To further investigate the role of MIS comparing patients submitted to MI-IDS with a balanced population treated by standard laparotomy. METHODS: The investigational arm (Cases) includes 30 AEOC patients treated with MI-IDS. The Control arm included a consecutive series of 65 AEOC patients submitted to laparotomic IDS. Inclusion criteria were: age>18years, histologically proven EOC, clinical complete/partial response after NACT, and ECOG PS <2. Preoperative clinical data, perioperative and oncological outcomes were analyzed. General Well-Being Schedule (GWBS) was administered to evaluate quality of life before and after surgery. RESULTS: Both groups were well-balanced. A higher percentage of women among Cases received bevacizumab-containing NACT compared with Controls. No statistical differences were registered in terms of surgical procedures and residual tumor. A significantly longer median OT in Cases was counterbalanced by more favorable EBL and median length of stay and TTC. No statistically significant differences were registered in terms of postoperative complications. Cases showed a 6months longer PFS compared to Controls. However, in multivariate analysis only the administration of Bevacizumab and a shorter TTC were independently associated with a longer PFS. Regarding QoL, no statistically significant differences were registered in Cases between pre- and postoperative GWBS score. Differently from Controls where this difference was statistically significant and a more intense distress were recorded. CONCLUSIONS: Minimally invasive approach could represent an advantageous alternative surgical way to perform interval debulking surgery in this specific subset of patients, with no impact on PFS. Based on these findings a randomized clinical trial is now under evaluation in our Institution.

RESUMO

BACKGROUND: Overweight/obese (OW/OB) women are at high risk to develop gestational diabetes mellitus (GDM) in pregnancy. AIM: To investigate, in pregnant OW/OB women, the longitudinal changes of adiponectin plasma levels, carbohydrate and lipid metabolism, and to identify if there is any association between adipokines and subsequent development of GDM. SUBJECTS AND METHODS: Thirty-two OW/OB normotensive normoglycaemic women at the beginning of pregnancy were studied. Adiponectin, insulin sensitivity (homeostasis model assessment, HOMA) and lipid panel were measured at 1st, 2nd and 3rd trimesters of pregnancy. The bioelectrical impedance to estimate the subject's body composition was also performed. RESULTS: Sixteen OW/OB women developed GDM. There were no significant differences with regard to age, BMI and body composition. Glycaemic and insulinaemic plasma levels, HOMA and lipid panel were comparable in the two groups. Systolic, diastolic and mean blood pressure at the 1st trimester were higher in OW/OB women with GDM (p < 0.05). GDM group showed adiponectin levels significantly lower than control group, at each trimester (p < 0.05). Adiponectin, fat mass, diastolic blood pressure and HOMA are independent predictors of GDM. CONCLUSIONS: OW/OB women who will develop GDM show lower adiponectin than euglycaemic group, across all pregnancy. Furthermore, at first trimester, they showed higher body fat and blood pressure levels than NGT group. Adiponectin, body fat, DBP and HOMA are independent predictors of GDM in OW/OB pregnant women. These results suggest the possibility of using adiponectin as early marker of GDM risk, at least in this cohort of women.

RESUMO

BACKGROUND: This study evaluates the effects of spinal anesthesia with hyperbaric bupivacaine plus sufentanil on bladder function in women undergoing cesarean section. SUBJECTS AND METHODS: Thirty caucasian healthy pregnants scheduled for elective Cesarean section under spinal anesthesia performed with hyperbaric bupivacaine plus sufentanil were enrolled. Filling cystometry, proprioceptive bladder sensation during cystometry, rate of spontaneous voiding, post void residual volume, anocutaneous and bulbocavernosus reflex were analyzed at 4, 6 and 8 hours after spinal anesthesia. RESULTS: The proportion of women experiencing first sensation, first desire and strong desire at 4 hours was significantly different from that reported at 6 and 8 hours (p < 0.05 for first sensation and p < 0.01 for first and strong desire). Significant differences were also observed between volumes at which first sensation arose at first measurement (4 hours) and at second and third measurements (p < 0.01). There was a significant difference in rate of spontaneous micturition, with 80% of patients at 8 hours able to spontaneously void versus 40% at 6 hours, (p < 0.01). Moreover, a lower percentage of women had absent and/or light reflexes at 4 hour than at 6 and 8 hours (p < 0.01). CONCLUSIONS: Spinal anesthesia with bupivacaine plus sufentanil causes a clinically significant disturbance on bladder function in women undergoing cesarean section. Even thought recovery of proprioceptive bladder sensation is fast, a full recovery of spontaneous voiding requires a much longer time. A close monitoring of urinary function and of bladder distension is, therefore, advisable.

RESUMO

PURPOSE: Coronary heart disease is the leading cause of morbidity and mortality in postmenopausal women. Among statins, pravastatin has been shown to significantly reduce fatal and non-fatal cardiovascular events in primary and secondary prevention trials. The aim of the present research was to investigate whether treatment with pravastatin can modify some indices of cardiovascular risk in healthy postmenopausal women such as significant reductions in total and LDL cholesterol and triglyceride levels. METHODS: 20 patients were randomized in double-blind fashion to treatment for eight weeks with either pravastatin 40 mg/day or placebo, and subsequently, after one-week wash-out, crossed-over to the alternative treatment (placebo or pravastatin) for the following eight weeks. We performed clinical and laboratory investigations, before and at the end of each treatment period, to evaluate patient response to the treatment with pravastatin. RESULTS: After eight weeks pravastatin therapy reduced the median low density lipoprotein (LDL) and total cholesterol (p < 0.01 in both cases). In contrast, insulin level and insulin sensitivity did not show any difference with regard to values observed after placebo treatment. The absolute number of endothelial progenitor cells-colony forming unit (EPC-CFU) was significantly increased by pravastatin treatment (30.6% increase, p < 0.05) and the number of senescent cells was significantly decreased. However pravastatin did not increase tube-like formation by EPC and did not improve endothelial function. CONCLUSIONS: Despite beneficial effect on lipids and EPC, short term pravastatin does not seem to improve other cardiovascular risk factors, at least in healthy postmenopausal women.

RESUMO

Preterm delivery is the chief problem in obstetrics today and the main determinant of infant mortality and morbidity. Despite the dramatic decrease in infant mortality rate during the past several years, the percentage of preterm (<37 weeks gestation) and low birth weight (LBW) (<2500) rates remain elevated. Approximately 10% of all births are preterm, with a rate of 1-2% of infant born before the end of the 32 weeks of gestation and with a weight <1500 g. Despite the importance of the problem, the majority of preterm live births remain unexplained, and programmatic attempts at reversing the high level of preterm births have not been successful. Numerous studies have linked bacterial vaginosis, chorioamniotitis and endometritis with preterm birth and LBW, especially among African women. The number of preterm live births among African women is twice the one among Caucasians. Bacterial vaginosis is an independent risk factor for preterm and LBW births and the mechanism by which bacterial vaginosis causes the preterm birth of an infant with LBW is unknown. The aim of this article was to underline the importance of the treatment and early identification of vaginal infection, in particular if due to bacterial vaginosis, as it can have a substantial affect on the incidence of preterm delivery with LBW.

RESUMO

In human seminal plasma a family of proteins that is immunologically related to the RSV-IV protein secreted under androgen control from the epithelium of the rat seminal vesicles was detected by a radioimmunoassay. Evidence for the origin of these antigens from human seminal vesicle is presented. Quantitative measurements of this family of proteins were performed in men with low levels of serum testosterone (idiopathic hypogonadotropic hypogonadism) and in individuals having serum testosterone in the normal range of values but carrying sex chromosome aberrations (Klinefelter's syndrome). In the first case we have found a marked decrease in the total amount of the RSV-IV-related proteins. An increase of about 40% in the total amount of these antigens was obtained in these subjects by gonadotropin treatment. A decreased amount of these proteins was also detected in the subjects affected by Klinefelter's syndrome. The possibility that some factor(s) under genetic control is involved, in addition to testosterone, in the regulation of this family of proteins is discussed.

RESUMO

In the seminal plasma of normal men a protein, immunologically related to a major protein (RSV-IV) secreted from the rat seminal vesicle epithelium, was detected by competition with RSV-IV in a specific radioimmunoassay using a rabbit anti RSV-IV antiserum. The protein was partly (80%) purified by column chromatography; characterization by gel electrophoresis indicated that the protein is slightly basic and has a molecular weight of 140 000. The protein was present on the surface of human spermatozoa as well as in the ejaculates of azoospermic men and it is believed to be a sperm-binding protein.
