RESUMEN
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.

PURPOSE: To determine whether a correlation exists between size, location, type of myomas and perioperative outcomes. METHODS: This is a observational study in women undergone to laparoscopic myomectomy (LM) because of single symptomatic myoma >4 cm in diameter. We collected data about general features, surgical outcomes, intraoperative/postoperative complications and time to return to normal activity. RESULTS: A total of 444 patients (mean age 36.7 ± 6.4 years) resulted eligible for the study. Myomas sized between 8 and 12 cm were linked to an increased amount of blood loss (significantly higher in intramural than subserosal myoma). The removal of intramural myomas >8 cm and the subserosal ones >12 cm required a significant longer surgical time. Patients returned 17.9 ± 9.5 days after surgery to their personal activities. Six cases (1.35 %) required conversion to laparotomy, and only in two cases blood transfusion was necessary. CONCLUSION: Myomas size and type represent the best predictors of surgical difficulties and possible intrapostoperative complications. Intramural myomas >8 cm and subserosal ones >12 cm should be considered as a challenging procedure. LM remains the gold standard approach because of very low perioperative complication rate and faster return to normal activity.

OBJECTIVE: Caesarean section (CS) rates have increased worldwide in recent decades. In 2015, the WHO proposed the use of the 10-group Robson classification as a global standard for assessing, monitoring and comparing CS rates both within healthcare facilities over time and between them. The aim of this study was to assess the pattern of CS rates according to the Robson classification and describe maternal and perinatal outcomes by group at the Tosamaganga Hospital in rural Tanzania. DESIGN: Observational retrospective study. SETTING: St. John of the Cross Tosamaganga Hospital, a referral centre in rural Tanzania. PARTICIPANTS: 3012 women who gave birth in Tosamaganga Hospital from 1 January to 30 June 2014 and from 1 March to 30 November 2015. RESULTS: The overall CS rate was 35.2%, and about 90% of women admitted for labour were in Robson groups 1 through 5. More than 40% of the CS carried out in the hospital were performed on nulliparous women at term with a single fetus in cephalic presentation (groups 1 and 3), and the most frequent indication for the procedure was previous uterine scar (39.2%). The majority of severe neonatal outcomes were observed in groups 1 (27.7%), 10 (24.5%) and 3 (19.1%). CONCLUSION: We recorded a high CS rate in Tosamaganga Hospital, particularly in low-risk patients groups (Robson groups 1 and 3). Our analysis of Robson classification and neonatal outcomes suggests the need to improve labour management at the hospital and to provide timely referrals in order to prevent women from arriving there in critical conditions.

Maspin expression in endometrial hyperplasia and endometrial endometrioid adenocarcinomas was assessed and its correlation with p53 and Ki67 expressions and clinical outcome, as well as its potential to distinguish typical from atypical endometrial hyperplasia, were assessed in this study. Histological sections from 114 cases of endometrial endometrioid adenocarcinoma, 75 cases of endometrial hyperplasia (typical and atypical), and 23 normal endometrial tissue samples were examined. The most representative hematoxylin-eosin slides were selected and 2-3 micron-thick sections were cut for immunohistochemical staining with maspin, p53, and Ki67 antibodies. While there was no maspin expression in normal endometrial cells, it was present in 14.5% of the patients with endometrial hyperplasia without atypia. Staining for maspin was positive in atypical hyperplasia and endometrial adenocarcinoma in, respectively, 45% and 49.1% of the cases studied. No statistically significant correlations were found between maspin and Ki-67 antibodies or p53 expression. Our findings showed that maspin expression, which generally correlates with a less aggressive behavior, is significantly higher in atypical hyperplasia and in endometrial endometrioid adenocarcinoma. Maspin positivity in endometrial hyperplasia could be used to identify pseudo-atypical hyperplasia and could be considered a potentially useful prognostic parameter in those cases in which adenocarcinomas are well differentiated.

RET/PTC rearrangement and BRAF(V600E) mutation are the two prevalent molecular alterations associated with papillary thyroid carcinoma (PTC), and their identification is increasingly being used as an adjunct to cytology in diagnosing PTC. However, there are caveats associated with the use of the molecular approach in fine-needle aspiration (FNA), particularly for RET/PTC, that should be taken into consideration. It has been claimed that a clonal or sporadic presence of this abnormality in follicular cells can distinguish between malignant and benign nodules. Nevertheless, the most commonly used PCR-based techniques lack the capacity to quantify the number of abnormal cells. Because fluorescence in situ hybridization (FISH) is the most sensitive method for detecting gene rearrangement in a single cell, we compared results from FISH and conventional RT-PCR obtained in FNA of a large cohort of consecutive patients with suspicious nodules and investigated the feasibility of setting a FISH-FNA threshold capable of distinguishing non-clonal from clonal molecular events. For this purpose, a home brew break-apart probe, able to recognize the physical breakage of RET, was designed. While a ≥3% FISH signal for broken RET was sufficient to distinguish nodules with abnormal follicular cells, only samples with a ≥6.8% break-apart FISH signal also exhibited positive RT-PCR results. On histological analysis, all nodules meeting the ≥6.8% threshold proved to be malignant. These data corroborate the power of FISH when compared with RT-PCR in quantifying the presence of RET/PTC in FNA and validate the RT-PCR efficiency in detecting clonal RET/PTC alterations.
