OBJECTIVE:In critically ill neonates, peripheral perfusion and oxygenation assessment may provide indirect information on the circulatory failure of vital organs during circulatory shock. The development of pulse oximetry has recently made it possible to calculate the perfusion index (PI), obtained from the ratio between the pulsatile and nonpulsatile signals of absorbed light. The main goals of this study were: (1) to study foot PI; and (2) to evaluate the relationship between foot PI, obtained continuously by pulse oximetry, and a number of variables, i.e. blood flow (BF), oxygen delivery (DO2), oxygen consumption (VO2), and fractional oxygen extraction (FOE), measured indirectly by near-infrared spectroscopy (NIRS) on the calf in 43 healthy term neonates (weight 3474.6±466.9 g; gestational age 39.1±1.4 weeks).STUDY DESIGN:Calf BF, DO2 and VO2 were assessed by NIRS on short-lived venous and arterial occlusion maneuvers. PI was measured on the contralateral foot.RESULTS:Foot PI was 1.26±0.39. There was a positive correlation between foot PI and both calf BF (r=0.32, p=0.03) and DO2 (r=0.32, p=0.03), but no correlation was found between foot PI and calf FOE and between foot PI and VO2.CONCLUSIONS:In the neonatal intensive care unit, continuously measuring foot PI by pulse oximetry seems clinically more feasible for peripheral perfusion monitoring than spot measurements of the calf BF and/or VO2 by indirect NIRS.

Abstract Operative laparoscopy is the gold standard in the treatment of endometriotic ovarian cysts. Excisional surgery is the best technique to prevent recurrences and improve symptoms but it may result in ovarian reserve damage due to the removal of healthy ovarian cortex. The aim of this study was to investigate the extent of the ovarian reserve damage after stripping technique of unilateral endometriomas, by dosing the Anti-Müllerian Hormone (AMH). This prospective study was conducted at the Center of Minimally Invasive Pelvic Surgery of the Department of Health of Woman and Child, University of Padua, from October 2010 to June 2012. Twenty-five women underwent excision of monolateral endometriosis ovarian cyst by stripping without accessing a bipolar coagulation and performing an intracortical suture. The AMH serum levels were estimated in the early proliferative phase of the cycle, before surgery (time 0), 24 h after surgery (time 1), the first menstrual cycle after surgery (time 2) and the third menstrual cycle after surgery (time 3). We found a nonstatistically significant decreases in serum AMH levels after surgical excision of the cysts. Our results suggest that an appropriate surgical technique, without the use of the bipolar coagulation of ovarian border, does not determine a significant reduction of ovarian reserve.

STUDY OBJECTIVE To evaluate long-term efficacy of type 2 myoma enucleation in toto. DESIGN Longitudinal retrospective study (Canadian Task Force classification II-2). SETTING University obstetrics and gynecology clinic. PATIENTS One hundred twelve women with menorrhagia and at least 1 type 2 submucous myoma who underwent hysteroscopic myoma enucleation in toto. INTERVENTION Clinical long-term follow-up. MEASUREMENTS AND MAIN RESULTS Success of the procedure and influence of myoma characteristics on recurrence of menorrhagia were evaluated. Mean (SD) follow-up was 58.4 (19.1) months. The success of the procedure was 88.4% (99 patients). Seventeen patients (15.2%) underwent a 2-step procedure. Among patients with relapsed menorrhagia, 10 (8.9%) underwent a repeat operation. Statistical analysis showed that number and diameter of myomas did not influence the outcome. Localization in the posterior wall of the uterus, compared with other sites, was associated with a higher percentage of resolution of menstrual symptoms (p = .03). There was no significant relationship between myomas features and risk of symptom recurrence during follow-up. The 2-step myomectomy was performed in patients with myomas >30 mm in diameter (p < .001). CONCLUSION Hysteroscopic enucleation in toto of type 2 myomas is a safe and effective technique in long-term management of premenopausal women with menorrhagia.

Abstract The objective of this longitudinal retrospective study was to evaluate the influence of submucosal myomas on pregnancy outcome in infertile patients after resectoscopic myomectomy. One-hundred and four women with at least a 1-year-long history of infertility and the presence of submucosal myomas as the only cause of infertility were selected after surgical treatment. Pregnancy, delivery and abortion rates were investigated. Patients were divided into three groups according to the myoma classification (G0, G1 and G2). Gestational outcomes were analyzed in the three groups correlated by size, location and number of fibroids. The total pregnancy rate was 85.8% and no difference was shown regarding myoma classification (G0 82.05% versus G1 87.09% versus G2 88.2%; p = ns). Pregnancy and delivery rates were not significantly related to the number, localization or diameter of the fibroids. The abortion rate was not statistically influenced by myoma type, but it was significantly interelated with myomas situated in the anterior uterine wall (p = 0.03). Pre-term delivery was significantly influenced by myomas localized in the fundic wall (p = 0.02). Caesarean section rates were not affected by the characteristics of the myomas. Our results support the idea that resectoscopic myomectomy should be offered to infertile women who wish to become pregnant independently of their localization and number.

Abstract To identify the appropriate management we review the current literature on the diagnostic and different surgical procedures to which the patients affected by Sertoli–Leyding cell tumors (SLCTs) were submitted. Through the description of a case report we also propose an interdisciplinary diagnostic approach and a laparoscopic surgical staging, with a long-term follow-up. The analysis shows that pelvic ultrasound is primary diagnostic procedure, and only 36% of publications clearly describe to have performed more specific investigation. The hormone assessment is performed in the presence of specific endocrine symptoms. Laparoscopic approach is chosen by a few surgeon. Laparotomic surgery is preferred based in not recent recommendations for ovarian cancer treatment, although it is demonstrated the efficacy and safety of laparoscopy in the treatment of ovarian epithelial tumors. Different steps that are usually used for oncological ovarian cancer staging are not always performed. Conservative and fertility sparing surgery is commonly accepted, and even preferred due to the young age of patients. In the surgical treatment of SLCTs is necessary to adopt common guidelines, and evenly define the steps that the patient should be submitted. If are observed epithelial cancer oncological principles, laparoscopic surgery should be the approach of choice for these patients.

PurposeRestoring the anatomical relationship and preserving the function of pelvic organs represent the ideal outcome of surgical intervention in patients suffering from endometriosis-related infertility. The aim of the study was to compare two large cohorts (Group A and Group B) of infertile patients in terms of postsurgical spontaneous/assisted fertility and perioperative surgical outcomes. The surgical treatment was performed by a skilled surgeon (Group A) and a surgeon dedicated to endometriosis-related infertility (Group B).MethodsAn observational cohort study on women affected by pelvic endometriosis who underwent laparoscopic treatment (to restore/improve their fertility) was conducted. A comparison, between Group A and Group B, in terms of perioperative surgical outcomes, clinical/ongoing pregnancy and live birth rates, spontaneous pregnancy rate and obstetrical outcome was performed.ResultsA significantly higher spontaneous fertility rate (particularly in the first year after surgery) and lower ectopic pregnancy rate were found in Group B. ART success rates were not affected by different surgical approaches. Perioperative and obstetrical outcomes were similar in both groups.ConclusionIn patients affected by endometriosis, the choice between expectant management versus intervention should be personalized: when the estimated probability of natural conception is low, surgery may be considered as a second-line treatment. Conversely, in all other cases surgery should be offered early (as a first-line approach) as it improves the chance of spontaneous conception. The laparoscopic treatment of infertility due to endometriosis must be performed by a skilled specialized surgeon to ensure a complete “pelvic cleanout” while respecting the anatomical structures and reducing the risk of fertility impairment due to surgical procedures.

Electrical surgical devices may determine tissue damage through lateral thermal spread and activation of inflammatory processes. Several tissue effects are associated with the use of different surgical instruments. The aim of the present study was to compare tissue damage following the application of cold knife biopsy, bipolar electrocoagulation and the ultracision harmonic scalpel, through the analysis of inflammatory gene mediator expression. Three fragments of the round ligament (length 0.5 cm) were obtained from 22 females who had undergone total or subtotal laparoscopic hysterectomy using three different modes of resection: Cold knife biopsy, bipolar electrocoagulation and ultracision harmonic scalpel. The tissue fragments were examined by quantitative polymerase chain reaction (qPCR) analysis of selected cytokines. Gene expression analysis demonstrated large standard deviations due to individual variability among patients and indicated variability in the concentrations of cytokines in the three different samples. The quantity of cytokine mRNA in the cold knife biopsy samples was generally greater than those obtained by other techniques. Tumor necrosis factor-α expression was significantly higher in the sample obtained with the ultracision harmonic scalpel and bipolar electrocoagulation (P=0.033) when compared with cold knife biopsy. The inflammatory response was analyzed by the quantification of gene expression through the use of qPCR. The ultracision harmonic scalpel and bipolar electrocoagulation triggered the inflammatory cascade and resulted in an increased production of cytokines compared with cold knife biopsy.

Fertility sparing surgery in young women affected by endometrial stromal sarcoma: an oncologic dilemma or a reliable option? review of literature starting from a peculiar case

Marco Noventa; Salvatore Gizzo; Lorena Conte; Angela Dalla Toffola; Pietro Litta; Carlo Saccardi

Background Endometrial stromal sarcoma (ESS) is a term used to define a rare neoplasm that accounts for approximately 0.2%–1% of all uterine malignancies; it is, however, implicated in an estimated 10%–15% of those malignancies with a mesenchymal component. Recent evidence suggests that while the preservation of the ovaries may be considered appropriate in premenopausal women, hysterectomy and bilateral salpingo-oophorectomy remains the recommended treatment in postmenopausal women. Currently, only a few case series reporting the treatment of ESS in young women with a desire to preserve fertility and thus subjected to a fertility-sparing surgery are available in the literature. Case presentation We report a peculiar case of early stage ESS treated by laparoscopic fertility-sparing surgery and a strict follow-up program (every 3 months) of imaging and clinical evaluation. The patient remained disease free 1 year after primary treatment. Three months after completing oncological follow-up, the patient conceived spontaneously and is, to date, pregnant at 11 weeks of gestation without evidence of recurrent disease or obstetric complications. Conclusion Based on our case report and in accordance with the data available, we suggest that in young patients affected by early stage ESS who wish to preserve reproductive function, fertility-sparing surgery could represent a valid option, though strict oncological follow-up remains mandatory.

Abstract We report the case of a 15-year-old woman with signs of hyperandrogenism affected by a Sertoli–Leydig cell tumor (SLCT). In our patient, blood analysis showed a high testosterone (T) level (T: 8.53 nmol/L; nv < 1.87 nmol/L) while the GnRH-analogue test demonstrated an exaggerated secretion of 17-hydroxyprogesterone (OHP), T, and androstenedione (A) by the ovary after stimulation. We compared the GnRH-analogue test of our patient with that obtained in a group of normal and healthy women (no. 8 subjects, 16–26 years old), men (no. 4 subjects, 18–28 years old), and in a group of PCOS patients with age and body weight compared. We found in our patient a value of OHP, 17-beta estradiol (E2) and T, from 2 to 18 times higher than healthy women. When we compared our patient with healthy men, we differently observed a comparable response of T. The response of our patient was also comparable with that observed in the PCOS group for E2. During the post-surgical follow up, the GnRH-analogue test of our patient showed a response of OHP, T, and E2 comparable with that of the PCOS group. The GnRH-analogue test is a useful tool to characterize steroidogenesis in SLCT. Chinese abstract 摘要 今天我们报道一例以高雄激素血症为特征的15岁的支持–睾丸间质细胞瘤(SLCT)个案。该患者血液化验提示睾酮升高,促性腺激素释放激素试验提示卵巢经刺激后分泌17-羟孕酮、睾酮、雄烯二酮升高。我们在患者、正常健康妇女、正常健康男性、多囊卵巢综合征患者间进行促性腺激素释放激素试验的比较。我们发现患者的17-羟孕酮、雌二醇、睾酮高于健康女性2-18倍。我们将患者和正常男性进行比较,发现对睾酮的反应不同。也观察了患者和多囊卵巢综合征患者对雌二醇的反应。在术后随访中,患者和多囊卵巢综合征患者的17-羟孕酮、睾酮、雌二醇的反应一致。促性腺激素释放激素类似物试验是测定支持–睾丸间质细胞瘤患者类固醇的一个有用的工具。

PurposeTo verify if different endometrial lesions determine the diagnostic symptom panel for a specific symptom.MethodsWe recruited 537 women with endometriosis who underwent laparoscopic surgery. Data on patient characteristics, severity of pelvic pain symptoms, disease stage and anatomical characteristics of endometriotic lesions were collected and analyzed by univariate analysis, followed by multiple logistic regression.ResultsWe observed a strong inverse relationship between pain symptoms and, respectively, the age of women at surgery (OR 0.885; p<0.05) and nulliparity (OR 5.6; p<0.05). A significant association between dysmenorrhea and nulliparity (OR 10.1; p< 0.01) and dysmenorrhea and rAFS stage (OR 4.7; p<0.05) was also confirmed. Finally a strong relationship was found between the presence of a rectovaginal endometriotic nodule and pain symptoms: dyspareunia (OR 13.8, p<0.001) and dysmenorrhea (OR 2.3, p<0.05). Significant relationships were found between the presence of peri-annexial adherences ...
