RESUMO

BACKGROUND: Endometrial scratching (ES) or injury is intentional damage to the endometrium performed to improve reproductive outcomes for infertile women desiring pregnancy. Moreover, recent systematic reviews with meta-analyses and randomized controlled trials demonstrated that ES is not effective, data on the safety are limited, and it should not be recommended in clinical practice. The aim of the current study was to assess the view and behavior towards ES among fertility specialists throughout infertility centers in Italy, and the relationship between these views and the attitudes towards the use of ES as an add-on in their commercial setting. METHODS: Online survey among infertility centers, affiliated to Italian Society of Human Reproduction (SIRU), was performed using a detailed questionnaire including 45 questions with the possibility to give "closed" multi-choice answers for 41 items and "open" answers for 4 items. Online data from the websites of the infertility centers resulting in affiliation with the specialists were also recorded and analyzed. The quality of information about ES given on infertility centers websites was assessed using a scoring matrix including 10 specific questions (scored from 0 to 2 points), and the possible scores ranged from 0 to 13 points ('excellent' if the score was 9 points or more, 'moderate' if the score was between 5 and 8, and 'poor' if it was 4 points or less). RESULTS: The response rate was of 60.6% (43 questionnaires / 71 infertility SIRU-affiliated centers). All included questionnaires were completed in their entirety. Most physicians (~ 70%) reported to offer ES to less than 10% of their patients. The procedure is mainly performed in the secretory phase (69.2%) using pipelle (61.5%), and usually in medical ambulatory (56.4%) before IVF cycles to improve implantation (71.8%) without drugs administration (e.g., pain drugs, antibiotics, anti-hemorrhagics, or others) before (76.8%) or after (64.1%) the procedure. Only a little proportion of infertility centers included in the analysis proposes formally the ES as an add-on procedure (9.3%), even if, when proposed, the full description of the indications, efficacy, safety, and costs is never addressed. However, the overall information quality of the websites was generally "poor" ranging from 3 to 8 and having a low total score (4.7 ± 1.6; mean ± standard deviation). CONCLUSIONS: In Italy, ES is a procedure still performed among fertility specialists for improving the implantation rate in IVF patients. Moreover, they have a poor attitude in proposing ES as an add-on in the commercial setting.

RESUMO

OBJECTIVE: To evaluate the role of emergency manual detorsion as first line management for testicular torsion in the context of the COVID-19 pandemic. METHODS: This retrospective observational study includes 90 pediatric patients ≤14 years old with diagnosis of testicular torsion made at 2 tertiary centers between October 2020 and June 2022. Variables examined included age, presentation delay, surgical wait time, number of attempts at manual testicular detorsion, and manual testicular detorsion success. All patients finally underwent surgery, including contralateral testicular fixation. Outcomes included predictors of successful manual detorsion, testicular findings at surgery, and operation time. RESULTS: Mean (SD) age at diagnosis was 11.51 (2.64) years. Mean presentation delay was 11.76 (13.79) hours. Detorsion was attempted in 72 (80%) patients, resulting successful in 58 (80.5%). Surgical wait time after successful manual detorsion was 22.85 (16.94) hours. On multivariable analysis, successful manual detorsion was associated with a presentation delay<6 hours (odds ratios [OR] 0.154, 95% confidence intervals (CI) 0.036-0.655, P = 0.01) and absence of scrotal edema (OR 0.171, 95% CI 0.038-0.769, P = 0.02). Vice versa, a heterogeneous echo-texture (OR 0.57, 95% CI 0.007-0.461, P = 0.007) and absent blood flow on Doppler ultrasound scan (OR 0.256, 95% CI 0.067-0.971, P = 0.045) were significantly associated with the likelihood of manual detorsion failure. CONCLUSION: In our experience, manual detorsion provided safe and effective emergency treatment for pediatric testicular torsion, especially in absence of edema and when presentation delay is <6 hours. This maneuver should be more widely attempted immediately after diagnosis as temporizing rescue.

RESUMO

BACKGROUND: Mature cystic teratomas of the ovary (MCTO) are a type of germ cell tumor that may contain well-differentiated tissues developed from three germ cell layers and constitute about 20% of ovarian germ cell tumors. They are rare ovarian tumors with an annual incidence variable from 1.2 to 14.2 cases per 100,000 that occur mainly in women of reproductive age. They are frequently benign with a slow growth rate, even if they can undergo a malignant transformation in about 1-2% of cases. CASE PRESENTATION: Here, we present the case of an elderly woman referred to gynecological first aid for acute abdominal pain and showing a giant and unusual MCTO at rapid growth with malignant transformation in squamous cell carcinoma (FIGO stage Ia). The patient underwent pelvic mass removal trough emergency longitudinal midline laparotomic incision with intraoperative frozen pathologic examination. A complete surgical staging during the first surgery was performed. After about 9 years of follow-up, she died of non-oncological reasons without recurrence. CONCLUSIONS: Present case highlights that CMTO with malignant transformation should always be suspected in elderly women in presence of pelvic mass at rapid growth, even if in absence of other clinical and ultrasonographic signs of malignancy. An intraoperative frozen pathologic examination may drive the best treatment.

RESUMO

Primary myoepithelial carcinoma of the lung (PMC-L) arising from the bronchial glands in lower respiratory tract is exceedingly rare. Thus far, few cases in adults and only one in a pediatric patient have been recorded. To our knowledge, this is the first report of PMC-L successfully removed in a child, focusing on the importance of multidisciplinary primary surgery for the treatment of this tumor. A 7-year-old girl was admitted for persistent cough and fever; she was unresponsive to oral antibiotics. Chest radiography showed loss of volume of left lung sustained by almost total atelectasis. After routine clinical investigations, she was referred for computed tomography scan and magnetic resonance imaging that documented the presence of a mass occupying the entire left upper lobe, infiltrating the pulmonary hilum (main bronchus, pulmonary artery, superior pulmonary vein, and pericardium). After multidisciplinary evaluation, the histopathologic diagnosis of PMC-L was established using ultrasonography-guided transthoracic core needle biopsy and bronchoscopic biopsies. She was then subjected to left pneumonectomy under extracorporeal circulation and positioning of a thoracic expander filled with 200 mL of saline solution. The postoperative course was uneventful. With TREP (very Rare Tumor in Pediatric Age) consent radiotherapy was performed (61.2 Gy). At the 10-month follow-up, the patient was alive, breathing normally without any oxygen support, without recurrence of PMC-L or metastasis, and without any chest deformity. To our knowledge, this is the first case where a pediatric patient was successfully operated for PMC-L involving the whole lung. Extracorporeal circulation enabled us to perform radical primary surgery. Prosthesis implant not only maintained normal chest expansion but also allowed focused radiotherapy, thus enabling us to prevent damage to vital organs.

RESUMO

Transglutaminase 2 (TG2) is a multifunctional enzyme and two isoforms, TG2-L and TG2-S, exerting opposite effects in the regulation of cell death and survival, have been revealed in cancer tissues. Notably, in cancer cells a hypoxic environment may stimulate tumor growth, invasion and metastasis. Here we aimed to characterize the role of TG2 isoforms in neuroblastoma cell fate under hypoxic conditions. The mRNA levels of TG2 isoforms, hypoxia-inducible factor (HIF)-1α, p16, cyclin D1 and B1, as well as markers of cell proliferation/death, DNA damage, and cell cycle were examined in SH-SY5Y (non-MYCN-amplified) and IMR-32 (MYCN-amplified) neuroblastoma cells in hypoxia/reoxygenation conditions. The exposure to hypoxia induced the up-regulation of HIF-1α in both cell lines. Hypoxic conditions caused the up-regulation of TG2-S and the reduction of cell viability/proliferation associated with DNA damage in SH-SY5Y cells, while in IMR-32 did not produce DNA damage, and increased the levels of both TG2 isoforms and proliferation markers. Different cell response to hypoxia can be mediated by TG2 isoforms in function of MYCN amplification status. A better understanding of the role of TG2 isoforms in neuroblastoma may open new venues in a diagnostic and therapeutic perspective.

RESUMO

BACKGROUND: The aim of this study is to investigate the use of methylene blue in perioperative identification of the patent processus vaginalis in a group of boys presenting with congenital or recurrent hydrocele where surgery was performed by junior surgeons in training. METHODS: We retrospectively reviewed the notes of 22 boys with hydrocele, of which two recurrences, who were operated via a standard inguinal approach, by trainees. Methylene blue 0.3-0.5 mL was injected into the hydrocele fluid through the scrotal wall. A processus vaginalis was identified as a blue line. RESULTS: Methylene blue injection clearly identified a patent processus vaginalis in 91% of patients. In 9% (N.=2), of which one recurrence, methylene blue injection demonstrated a hydrocele with an obliterated processus vaginalis. There were no intraoperative complications. No testicular atrophy was recorded. CONCLUSIONS: Injection of methylene blue into the hydrocele sac may be considered a useful aid for a clearer identification of a difficult patent processus vaginalis. In the present series, there were no complications, and thus we believe that this technique might be suitable and especially helpful, in cases of recurrent hydrocele, and for junior surgeons in training.

RESUMO

INTRODUCTION: CO2 pneumoperitoneum can influence the biological behavior of neuroblastoma (NB). Angiogenesis and genetic features are responsible for malignant phenotype of this tumor. We examined the CO2 effects on N-Myc, vascular endothelial growth factor (VEGF), and matrix metalloproteinase-2 (MMP-2) expression as critical biomarkers of tumor invasiveness, in NB cells without N-Myc amplification. MATERIALS AND METHODS: SH-SY5Y cells were exposed to CO2 (100%) at 15 mm Hg pressure for 4 hours and then moved to normal condition for 24 hours. Control cells were incubated with 5% CO2 for the same time. In control and CO2-exposed cells, the messenger ribonucleic acid (mRNA) levels of hypoxia-inducible factor (HIF)-1α, HIF-2α, VEGF-A, and MMP-2 were quantified by real-time polymerase chain reaction. N-Myc expression was evaluated by Western blot analysis. RESULTS: The exposure to 15 mm Hg CO2 (100%) for 4 hours induced an increase in HIF-1α, but not in HIF-2α, mRNA levels. No differences were observed in N-Myc expression between exposed and control cells at each incubation time. Similarly, no significant differences were found for VEGF-A and MMP-2 transcript levels. In CO2 exposed cells, we observed only a slight increase in both VEGF-A and MMP-2 mRNA levels after 4 and 24 hours in comparison to controls. CONCLUSION: In our study, the hypoxic environment induced by CO2 exposure does not affect the expression of critical biomarkers of NB aggressiveness, such as N-Myc, VEGF, and MMP-2, in human SH-SY5Y NB cells without N-Myc amplification. These data suggest that CO2 pneumoperitoneum might not adversely impact NB cell invasiveness; however, it is necessary to evaluate these effects in others in vitro and in vivo models.

RESUMO

BACKGROUND: Lichen sclerosus (LS) is a disease of the skin of unclear etiology that can occur in the foreskin. Topical therapy with corticosteroids is recommended, but they can have side effects. OBJECTIVES: We aimed to compare the effects of ozonides with vitamin E acetate (OZOILE) versus topical corticosteroid in children undergoing circumcision. METHOD: Twenty children undergoing circumcision were treated before surgery: 10 children with OZOILE cream and 10 with 0.1% mometasone furoate once a day for 7 days. Ten age-matched patients with LS of the foreskin without any treatment were recruited as controls. Transcript levels of proinflammatory and anti-inflammatory cytokines and e-cadherin were evaluated in removed foreskins by qRT-PCR. RESULTS: OZOILE and steroid topical treatment produced a similar reduction of TNF-α and IL-1ß mRNA levels in foreskins from patients with LS when compared to untreated patients (p < 0.001). OZOILE and steroid treatment caused an increase in the transcript levels of IL-13 and e-cadherin in the foreskin of patients affected by LS in comparison to untreated foreskin (p < 0.001). CONCLUSIONS: On the basis of our biochemical data, a randomized clinical trial might be useful to verify the actual clinical effect of OZOILE as alternative treatment to corticosteroids in children affected by LS of the foreskin.

RESUMO

INTRODUCTION: To evaluate the outcome of circumcised patients with balanitis xerotica obliterans (BXO) using uroflowmetry (UF). METHODS: Between 2011 and 2013, 180 children underwent a circumcision for phimosis. The foreskin was examined on microscopy. Patients with an histological diagnosis of BXO were included in the study. Patients with BXO underwent UF two weeks after surgery and treatment with clobetasol propionate ointment. Patients were re-evaluated at 6, 12, 18 and 24 months postoperatively clinically and using UF. RESULTS: 75 of 180 circumcised patients (41.6%) were included. At two weeks, Thirtytwo of 75 patients (42.7%) displayed a pathological UF. At six months, 15 patients (20%) had pathological UF and a new cycle of clobetasol was prescribed. At one year, 10 patients (13.3%) displayed patholgocial UF and underwent progressive urethral dilatation or meatoplasty. At 18 months, 71 patients (94.7%) displayed regular UF, 3 underwent a meatoplasty and one a staged urethroplasty for a severe urethral stenosis. At two years, UF was normal in 74 out of 75 (98.7%). CONCLUSIONS: We recommend to send for hystological examination all foreskins excised after circumcision. We believe that a clinical and uroflowmetric follow-up of pediatric patients with BXO is mandatory for a prompt identification of post-voiding dysfunction.

RESUMO

PURPOSE: Testicular torsion (TT) mainly affects boys under 18 years old. To avoid orchiectomy, TT requires an immediate operative management. The etiology of TT is still controversial. Observed familiar recurrence suggests the presence of a genetic involvement. The INSL3 gene consists of two exons, and it is specifically expressed in fetal and adult Leydig cells. In transgenic mice, deletion of this gene was observed an increased testicular mobility and testicular torsion. We have hypothesized the possible involvement of the INSL3 gene as a predisposing factor of human TT. METHODS: We performed genetic analysis in 25 pediatric patients with unilateral and intravaginal TT (left, n = 13, 56%; right, n = 12, 48%). The age of the patients ranged from 1 to 16 years (median age n = 10.4 ± 5.46 years). In this study, we included two first male cousins affected by TT. Venous peripheral blood samples was obtained after parental written informed consent. RESULTS: The Thr60Ala polymorphism was detected in exon 1 of INSL3 gene and other 2 rarer variants (rs1047233 and rs1003887) were identified in the 3' untranslated region. These variants are prevalent in patients with TT instead of healthy subjects. CONCLUSIONS: Additional studies in a larger population are needed to better understand the clinical consequence of the INSL 3 variations founded. This would allow in the future to identify the patients at risk of TT to improve clinical management.

RESUMO

Balanitis xerotica obliterans (BXO) is a chronic inflammatory skin disorder, considered the male genital variant of lichen sclerosus. Anti-inflammatory drugs are commonly used in BXO. We evaluated the effects of an innovative formulation of ozonated olive oil with vitamin E acetate (OZOILE®) on the inflammatory status and tissue remodeling in male children with BXO. The mRNA transcripts of proteins involved either in inflammation or in dynamics of tissue regeneration were analyzed by quantitative real-time PCR, in foreskins affected by BXO removed from patients untreated or treated with OZOILE® cream for 7 days before circumcision. We found a significant reduction in mRNA levels of IL-1ß, TNF-α, INF-γ, transglutaminase 2 and NOS2 in foreskins treated with OZOILE® in comparison to untreated ones (p < 0.001). No significant differences were observed in NF-κB activation in the specimens obtained from treated and untreated patients. Hence, OZOILE® treatment up-regulated hypoxia-inducible factor (HIF)-1alpha, vascular endothelial growth factor (VEGF) and E-cadherin gene expression (p < 0.001). The treatment with OZOILE® showed effective results in children affected by BXO by reducing the inflammatory process and stimulating mechanisms for tissue regeneration of the foreskin. A randomized clinical trial on a large number of children affected by BXO might be useful to verify the efficacy of topical treatment with OZOILE®.

RESUMO

Preoperative anxiety is a major problem in paediatric surgical patients. Melatonin has been used as a premedicant agent and data regarding effectiveness are controversial. The primary outcome of this randomized clinical trial was to evaluate the effectiveness of oral melatonin premedication, in comparison to midazolam, in reducing preoperative anxiety in children undergoing elective surgery. As secondary outcome, compliance to intravenous induction anaesthesia was assessed. There were 80 children undergoing surgery randomly assigned, 40 per group, to receive oral midazolam (0.5 mg/kg, max 20 mg) or oral melatonin (0.5 mg/kg, max 20 mg). Trait anxiety of children and their mothers (State-Trait Anxiety Inventory) at admission, preoperative anxiety and during anaesthesia induction (Modified Yale Pre-operative Anxiety Scale), and children's compliance with anaesthesia induction (Induction Compliance Checklist) were all assessed. Children premedicated with melatonin and midazolam did not show significant differences in preoperative anxiety levels, either in the preoperative room or during anaesthesia induction. Moreover, compliance during anaesthesia induction was similar in both groups. CONCLUSIONS: This study adds new encouraging data, further supporting the potential use of melatonin premedication in reducing anxiety and improving compliance to induction of anaesthesia in children undergoing surgery. Nevertheless, further larger controlled clinical trials are needed to confirm the real effectiveness of melatonin as a premedicant agent in paediatric population. What is Known: • Although midazolam represents the preferred treatment as a premedication for children before induction of anaesthesia, it has several side effects. • Melatonin has been successfully used as a premedicant agent in adults, while data regarding effectiveness in children are controversial. What is New: • In this study, melatonin was as effective as midazolam in reducing children's anxiety in both preoperative room and at induction of anaesthesia.

RESUMO

Aim of the study is to report the experience in the last three years about endourological treatment of newborns affected by genito- and urinary malformation, implying critical urinary tract dilatation and bladder mass requiring a neonatal operative management. Seven - four males and three female - patients were treated cystoscopically during the neonatal period. Three newborns with a posterior urethral valves (PUV), underwent a successful ablation of PUV. In a male with infected persistent large mullerian duct and subsequent acute urinary retention, a cystoscopically-assisted catheterization was performed. Two females, one with cloaca and the other with high persistent urogenital sinus and massive associated hydrometrocolpos underwent a cystoscopical drainage of the vagina and a positioning of a balloon catheter into the bladder. Another female with a bladder mass had a endoscopical biopsy. Thanks to modern neonatal operative urethrocystoscope, today is possible to treat early many pathological genito-urinary conditions in newborns.

RESUMO

INTRODUCTION: Classically, surgical approach for palpable undescended testis (pUDT) consists is an inguinal orchidopexy. In fact, a double incision allows an adequate mobilization of the spermatic cord and an easy dissection of a patent processus vaginalis and also to perform a subdartos pouch. For reduce potential mobility of the inguinal approach, in 1989 Bianchi and Squire proposed a transcrotal orchidopexy, using a high scrotal incision. We report our experiences and retrospectively evaluate the feasibility and postoperative success of the transcrotal approach for treatment of pUDT. PATIENTS AND METHODS: From January 2012 to June 2014, 217 patients, affected by pUDT were treated at our Institution, for a total of 231 orchidopexies (203 monolateral pUDT, 14 bilateral pUDT). Patients, in whom, under anesthesia, the testis could be moved to the neck of the scrotum, have been treated with a transcrotal approach using a high scrotal incision. All patients have been clinically followed up at 1 week and at 1, 2, 3, and 6 months, at 1 year, and then annually and using scrotal sonography with color-Doppler at 2, 3, and 6 months. RESULTS: A total of 205 pUDT (88.7%) were considered eligible for transcrotal. Eight (3.9%) pUDT, that were first approached transcrotally, have been converted to inguinal approach. At follow-up, two moderate scrotal hematomas and one inguinal hernia were noted. No recurrence or testicular atrophy was showed in transcrotal approached testes, while 2 recurrences out of 26 procedures (7.7%) were displayed after inguinal orchidopexy. CONCLUSIONS: In our experience, transcrotal approach is possible in almost 90% of pUDT. No major complication, such as recurrence or testicular atrophy, has been complained. Just 3 out of the 205 cases (1.5%) reported minor complications and 1 of which required a successful day-case procedure. Our data confirm that transcrotal orchidopexy can be considered effective, safe, and with a success rate being equivalent or better to classical inguinal approach.

RESUMO

PURPOSE: We evaluated in vitro the role of CO(2)-induced oxidative stress on the expression of proteins involved in cell-cycle regulation of neuroblastoma cells. METHODS: SH-SY5Y cells were exposed to CO(2) at 15 mmHg pressure (100 %) for 4 h and then moved to normal condition for 24 h. Control cells were maintained in 5 % CO(2) for the same time. ROS production was determined by fluorescent staining with H2DCF-DA. DNA damage was measured by COMET assay. p53 protein expression was analyzed by western blot and confocal laser scanning microscopy was used to evaluate its sub-cellular localization. Cyclin expression was quantified by real-time PCR and western blot. Cell-cycle analysis was performed by FACS. RESULTS: CO(2) incubation was associated with an increase in ROS production (p < 0.01), cell DNA damage mainly after 24 h (12 % increase of tail DNA content and 4-fold increase of tail length) and a significant up-regulation in p53 expression at 24 h with an intense nuclear staining. In CO(2)-treated cells, we observed an S-phase arrest in correlation with a reduction of cyclin B1 expression. CONCLUSIONS: In vitro-simulated pneumoperitoneum environment with CO(2) induces oxidative stress and cell DNA damage, leading to p53 up-regulation involved in cell-cycle arrest of neuroblastoma cells.

RESUMO

Port-site metastases, also called trocar-site metastasis, have been described after laparoscopic surgery for non-gynecological and gynecological cancers. The aim of this review was to obtain evidence for port-site metastases after laparoscopic surgical staging of endometrial cancer. A systematic search of published and unpublished cases of port-site metastases after laparoscopic staging of endometrial cancer was conducted. All the authors responsible for correspondence were contacted to obtain any missing data. The patients' characteristics and oncologic, surgical, and safety data were recorded and analyzed. Twelve cases of port-site metastases were identified and examined. In 4 cases they were "isolated," that is, recurrence without association with peritoneal carcinomatosis, whereas in 8 cases they were "nonisolated." The port-site metastases did not occur as a result of trocar site localization or dimension. No univocal strategy to prevent port-site metastases was adopted. Among patients with nonisolated port-site metastases, an aggressive histologic condition and a high grade were found in 3 of 6 patients and in 3 of 5 patients, respectively. Among patients with isolated port-site metastases, an early-stage endometrioid adenocarcinoma G2 endometrial cancer and a stage IIB G2 endometrioid adenocarcinoma were described in 3 of 4 patients and in only 1 case, respectively. All the patients with nonisolated port-site metastases died of disease. Similarly, among patients with isolated port-site metastases, only 1 was alive and free of disease after 10 months from recurrence diagnosis. Port-site metastases of endometrial cancer are an entity rarely reported but probably the expression of an aggressive disease. The available data do not allow us to draw conclusions or suggestions for their prevention and the treatment.

RESUMO

OBJECTIVE: Foetal exposure to high testosterone concentrations seems to be involved in the development of mammalian brain and related to pervasive developmental disorders (PDDs). The aim of the current study was to test the hypothesis that children born from hyperandrogenic women with polycystic ovary syndrome (PCOS) are at higher risk of PDDs. DESIGN: Longitudinal case-control study. PATIENTS: Thirty pregnant PCOS patients with hyperandrogenaemia and other 45 pregnant healthy women were followed during pregnancy. All women had a healthy baby. MEASUREMENTS: Clinical evaluations and biochemical assays of the mothers during pregnancy and after delivery were performed. The children's versions of the Autism-Spectrum Quotient (AQ-C), the Empathy Quotient (EQ-C) and Systemizing Quotient (SQ-C) tests were administered. RESULTS: Total AQ-C and communication scores were significantly higher for children of PCOS patients. Stratifying our population according to sex, total AQ-C, communication and attention switching subscores were significantly higher only for daughters of PCOS patients. EQ-C and SQ-C scores resulted in significantly lower and higher scores, respectively, only in daughters of PCOS patients in comparison with those of healthy non-PCOS controls. AQ-C, EQ-C and SQ-C scores, irrespective of the studied group and/or subclassification by gender, were significantly influenced by amniotic testosterone levels. CONCLUSIONS: Daughters of mothers affected by hyperandrogenic PCOS seem to have a higher risk for PDDs probably due to an unbalanced prenatal exposure to high levels of testosterone.

RESUMO

CONTEXT: Previous experimental and clinical data suggest impaired decidual trophoblast invasion in patients with polycystic ovarian syndrome (PCOS). OBJECTIVE: The objective of the study was to test the hypothesis that decidual endovascular trophoblast invasion in pregnant patients with PCOS is impaired and to clarify the potential mechanisms involved. DESIGN: This was an experimental case-control study. SETTING: The study was conducted at the academic Departments of Obstetrics and Gynecology and the Unit of Pathology (Italy). PATIENTS: Forty-five pregnant subjects screened from a wide population of women waiting for legal pregnancy termination were included in the final analysis. Specifically, 15 pregnant patients with PCOS were enrolled as cases and another 30 age- and body mass index (BMI)-matched healthy pregnant women without any feature of PCOS were enrolled as the controls. INTERVENTION: Interventions included the collection of trophoblastic and decidual tissue at the 12th week of gestation. MAIN OUTCOME MEASURES: Clinical, ultrasonographic, and biochemical data as well as the histological analysis of decidual endovascular trophoblast invasion. RESULTS: The rate of implantation site vessels with endovascular trophoblast invasion (ratio between total number of implantation site vessels and total number of vessels with endovascular trophoblast invasion) and the extent of endovascular trophoblast invasion (proportion between immunoreactive areas to cytokeratin 7 and to CD34) were significantly lower in patients with PCOS compared with healthy non-PCOS controls. Endovascular trophoblast invasion data were significantly and indirectly related to the markers of insulin resistance and testosterone concentrations in PCOS patients. CONCLUSIONS: Pregnant patients with PCOS patients have impaired decidual trophoblast invasion. Further studies are needed to evaluate the exact mechanisms through which insulin resistance and hyperandrogenemia exert this effect.

RESUMO

OBJECTIVE: Primary megaureter (PM) represents 6-10% of all antenatal displaced urinary malformations. Spontaneous resolution of PM is a well-known event. This long-term follow-up study evaluated the incidence and rate of resolution of PM. Some predictive factors were revised, based on morphological classification and scintigraphic pattern. MATERIAL AND METHODS: Sixty neonates with PM were followed. The diagnosis was confirmed by ultrasound examination and (99m)Tc-DTPA diuretic renal scan. All the observed patients underwent antibiotic prophylaxis. All conservatively treated children were followed from 6 months to 15 years. Follow-up consisted of monthly urine cultures, renal ultrasound and DTPA diuretic renography. Hydroureteronephrosis was considered to have resolved when a retrovesical cross-sectional diameter of ureter less than 6 mm was found. RESULTS: In total, 72 PM were identified in this series. At the end of the follow-up period, 38 PM (52.8%) had resolved, in 18 PM (25%) ureteral dilatation persisted and 16 PM (22.2%) required a surgical procedure. The median age at resolution was significantly affected by presenting hydronephrosis grade and cross-sectional diameter at diagnosis, but not by gender. The (99m)Tc-DTPA renogram results showed no functional impairment in resolved and persisting cases, even after long-term observation. CONCLUSIONS: The data show that 22% of neonatal PM require surgical treatment. Poor drainage on (99m)Tc-DTPA scan, grade IV-V hydronephrosis and ureteric diameter more than 15.0 mm were statistically significant and independent predictive factors for surgery. The time to spontaneous resolution in neonatally diagnosed PM may exceed 3.6 years, after which recovery is rare.

RESUMO

OBJECTIVE: To test the hypothesis that the risk of persistent glucose impairment after gestational diabetes mellitus (GDM) is increased in patients with polycystic ovary syndrome (PCOS). RESEARCH DESIGN AND METHODS: The prospective case-control study included 42 pregnant patients with PCOS and GDM and 84 pregnant control patients with GDM but without clinical and biochemical hyperandrogenism, polycystic ovaries, and oligo-anovulation. The case and control subjects were matched one to two for age and BMI. The glycemic profiles were studied in all subjects 6 weeks, 12 weeks, and 18 months after delivery. The incidence and the relative risk (RR) were calculated for overall persistence of an abnormal glycemic pattern and for each specific alteration, i.e., impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and diabetes mellitus (DM). RESULTS: At 18 months after delivery, the incidences of IFG, IGT, and IFG-IGT were significantly (P < 0.05) higher in the cases than in the controls. At the 18-month follow-up, the RR for the composite outcome of glucose metabolism impairment in PCOS women was 3.45 (95% CI 1.82-6.58). CONCLUSIONS: Patients with PCOS are at increased risk for a persistent impaired glucose metabolism after GDM.
