ABSTRACT
AIMS: To evaluate the feasibility and safety of robotic radical hysterectomy (RRH) with pelvic lymphadenectomy for locally advanced cervical cancer (LACC) after neoadjuvant chemotherapy (NACT). METHODS: Starting from 04/2009, consecutive patients with LACC were submitted to robotic surgical staging after NACT. Surgical outcomes were compared to those achieved by women undergoing robotic surgery for an early stage disease during the same temporal interval. RESULTS: Overall 25 (Group 1) and 21 (Group 2) patients had an early stage and a LACC, respectively. Among women with LACC, 18 achieved best tumor responses to NACT and therefore they were addressed to RRH. Outcomes resulted comparable between Groups in terms of operative time, blood loss, hospitalization and complications. No differences were found in terms of nodal yield, parametrial and vaginal cuff length. CONCLUSIONS: RRH is feasible and safe also in patients previously submitted to NACT for LACC. Larger series with longer follow-up are mandatory to establish survival outcomes.

The main aim of this work was to analyse the diversity of wild Saccharomyces cerevisiae isolated from spontaneous fermentations of grapes collected from heroic vine-growing area. A first screening based on several technological traits was used to select 39 strains among 132 isolates. By using three molecular typing techniques (evaluation of cell wall gene polymorphisms, mtDNA restriction analysis, inter-delta amplification analysis) a significant genetic variability was found. The analysis of principal aromatic compounds produced during inoculated fermentation of two grape musts demonstrated the strain impact on wine flavour and a significant influence of grape must on strain metabolic behavior. One selected strain was used in fermentation at cellar level and the analysis of inter-delta region on yeast colonies isolated during the process revealed the high-implantation ability of this strain. The obtained results demonstrate the usefulness of different molecular and technological markers for the evaluation of natural biodiversity among S. cerevisiae strains. This study represents an essential step towards the exploitation and the preservation of biodiversity of strains isolated from heroic vine-growing area. Selected S. cerevisiae strains could represent starter cultures available for winemakers addressed to production of quality premium wines maintaining differential properties of their own area.

AIMS: To evaluate the feasibility and safety of robotic radical parametrectomy (RRP) and pelvic lymphadenectomy for the management of occult invasive cervical cancer or local recurrence of endometrial cancer and to compare our outcomes with the evidence available in the literature. METHODS: Starting from 07/2008 consecutive patients submitted to RRP have been included in this study. A comprehensive literature review of published papers about this subject was carried out. RESULTS: During the study period 11 patients were managed; 7 and 4 patients had an occult cervical cancer and a vaginal recurrence of endometrial cancer, respectively. One intra-operative and one post-operative complications were recorded. Neither conversion to laparotomy, nor blood transfusions occurred. Three women required further adjuvant therapies. After a median follow-up of 19 months (range 8-36) one recurrence has been detected. The outcomes of other 200 women from 15 different papers have been collected and compared to our findings. CONCLUSIONS: Robotic surgery represents an effective alternative to accomplish radical parametrectomy with comparable results of those reported in the literature in terms of feasibility and safety. RRP is certainly a demanding procedure which however avoids radiotherapy in more than 80% of cases.

The implementation of early detection protocols and advanced treatment strategies has significantly improved survival outcomes for gynecologic cancer patients. The improvement of oncological outcomes has led to an increased attention toward Quality of Life issues, including the childbearing potential for young women. Traditionally the surgical treatment of cervical, endometrial and ovarian cancers involves the removal of the uterus and adnexa, irrespective of the impact on fertility and parenthood and regardless of patient desires. For young women affected by gynecological malignancies at an apparently early stage, fertility-sparing procedures could be offered. The aim of our review is to going through the available evidence in the Literature and to evaluate the current state of art regarding fertility-sparing procedures for women with gynecological malignancies in terms of oncological and fertility outcomes.

OBJECTIVE: To test the hypothesis that intrauterine growth restriction (IUGR) is associated with decreased thymus size in the human fetus. METHODS: The thymus perimeter was measured in 60 consecutive IUGR fetuses at prenatal ultrasound examination. IUGR was defined as an abdominal circumference (AC) <5(th) centile. Sixty controls were identified by selection of the next consecutive appropriately grown fetus of similar gestational age (+/-1 week). To exclude fetal size effects, ratios between thymus perimeter and fetal biometry measurements including biparietal diameter (BPD), AC and femur length (FL), as well as estimated fetal weight (EFW) were compared between IUGR fetuses and controls. RESULTS: The proportion of fetuses with thymus perimeter <5(th) centile for gestation was significantly higher in IUGR fetuses than in controls (58/60 vs. 7/60, P < 0.0001). The mean thymus perimeter/BPD ratio (0.87 +/- 0.20 vs. 1.13 +/- 0.13, P < 0.0001), thymus perimeter/AC ratio (0.28 +/- 0.06 vs. 0.35 +/- 0.03, P < 0.0001), thymus perimeter/FL ratio (1.18 +/- 0.26 vs. 1.51 +/- 0.19, P < 0.001) and thymus perimeter/EFW ratio (0.05 +/- 0.01 vs. 0.06 +/- 0.01, P = 0.02) were significantly lower in IUGR fetuses than in controls. There was a significant positive correlation between the observed-to-expected mean for gestation thymus perimeter ratio and the enrollment-to-delivery interval (r = 0.44, P < 0.001). CONCLUSION: IUGR is associated with a disproportionately small thymus. This supports the hypothesis that thymic involution may be part of the fetal neuroendocrine response to intrauterine starvation.

The study was aimed to test the hypothesis that preservation of the fallopian tubes at the time of total laparoscopic hysterectomy (TLH) increases the risk for postoperative infection. The study group consisted of 137 consecutive women undergoing TLH with conservation of the ovaries, who had concomitant bilateral total salpingectomy at the time of TLH. The control group included 145 women who had had TLH without salpingo-oophorectomy before the study period. Women undergoing bilateral total salpingectomy at the time of TLH had a lower rate of infectious morbidity compared with those who had TLH alone (3/137 versus 14/145, P = 0.01). Multivariable analysis showed that bilateral total salpingectomy at the time of TLH and blood loss are independent predictors of infectious morbidity.

The purpose of this study was to evaluate the feasibility and surgical outcome of a policy of routine specimen retrieval through the umbilical port, avoiding the enlargement of ancillary port-site incisions. A total of 1116 women underwent laparoscopic surgery for the treatment of a pelvic mass with extraction of the specimen through the umbilical port site (a total of 1453 retrieval procedures). All retrieval procedures were successfully carried out with this technique. Neither intraoperative complication related to the retrieval procedure nor accidental rupture of the endoscopic bag occurred. There was an injury to the epigastric artery. Neither trocar-site hernias (both umbilical trocar insertion sites and extraumbilical sites) nor port-site metastases occurred.

OBJECTIVE: To evaluate the feasibility and safety of laparoscopic management of adnexal masses > or = 10 cm in size. DESIGN: Prospective cohort study. SETTING: Two Gynecology Departments of University Hospitals. POPULATION: All women presenting with an adnexal mass > or = 10 cm in diameter were candidates for laparoscopic management. Women were excluded from laparoscopic approach if there was evidence of ascites or gross metastatic disease. Neither the sonographic features of the cyst nor elevated serum CA125 level was used to exclude women from having a laparoscopic approach. METHODS: A single operative protocol was followed for all women. All removed specimens were sent for immediate pathological evaluation. MAIN OUTCOME MEASURES: Rate of conversion to laparotomy, incidence of cancer encountered, and operative complications. RESULTS: One hundred and eighty-six women underwent laparoscopic evaluation for an adnexal mass of 10 cm or larger in size. The average preoperative mass size was 12.1 +/- 4.9 cm. A benign pathological condition was found in 86.6% (161/186) of the women, primary ovarian cancer in 16 (8.6%) women, a metastatic tumour of gastrointestinal origin in 1 (0.5%) woman, and a low malignant potential ovarian tumour in 8 (4.3%) women. Laparoscopic management was successful for 174 (93.5%) women. Reasons for conversion to laparotomy included anticipated technical difficulty (n = 7) and malignancy (n = 5). No intraoperative complications occurred in the entire study group. CONCLUSIONS: The vast majority of large adnexal masses can be safely resected laparoscopically, provided that there is expertise in laparoscopic surgery, immediate access to frozen section diagnosis, and preparation of patient to receive an adequate cancer surgery where indicated.

OBJECTIVE: To determine whether a large cross-sectional area of the umbilical cord is a predictor of fetal macrosomia. METHODS: Consecutive patients of > 34 weeks' gestation, who presented for sonographic examination and who delivered within 4 weeks of the examination, were included in the study. The sonographic cross-sectional areas of the umbilical cord, the umbilical vessels and the Wharton's jelly were measured in a free loop of the umbilical cord. Logistic regression analysis was used to determine significant predictors of macrosomia (actual birth weight > 4000 g and > 4500 g). Fetal biometric parameters (biparietal diameter, abdominal circumference and femur length), sonographic estimated fetal weight and umbilical cord area > 95(th) centile for gestational age were used as covariates. RESULTS: During the study period, 1026 patients were enrolled. Fifty-three (5.2%) newborns had a birth weight > 4000 g, and 22 (2.1%) weighed > 4500 g. The proportion of cases with a large umbilical cord was significantly higher in the group of macrosomic compared with non-macrosomic infants (54.7% vs. 8.7%, P < 0.0001). Multiple regression models demonstrated an independent contribution of the large cord in the prediction of birth weight > 4000 g and > 4500 g (odds ratio (95% CI), 20.6 (9.2-45.9) and 4.2 (1.2-17.7), respectively). The sensitivity, specificity and positive and negative predictive values of a sonographic large umbilical cord were 54.7%, 91.3%, 25.4%, and 97.4%, respectively. The combination of abdominal circumference > 95(th) centile and large cord predicted 100% of macrosomic infants. The proportion of umbilical cords with a Wharton's jelly area > 95(th) centile for gestation was significantly higher in macrosomic fetuses of diabetic compared with non-diabetic mothers. CONCLUSIONS: Sonographic assessment of umbilical cord area may improve the prediction of fetal macrosomia.
