Endometriosis is the presence of endometrial tissue in abnormal locations outside the uterine cavity. These locations are usually the ovaries, the peritoneum, and the uterine ligaments. Less frequently, the endometrial tissue can affect the perineum especially after surgical procedures or obstetric lesions. In this case report, we describe the case of a patient suffering from pain and swelling, with a sizeable nodule in an old episiotomy scar. Clinical examination, ultrasonography (USG) and magnetic resonance imaging (MRI) helped evoke the diagnosis of perineal endometriosis, and there were no signs of other endometriosis locations. Hormonal treatment was provided at first, but there was no clinical improvement after three months, so the treatment had to be surgical. Histopathological examination of the endometriotic mass confirmed the diagnosis. There were no immediate postoperative complications, and no clinical symptoms or recurrence signs six months and one year after.

BACKGROUND: Each subgroup of immune cells has a different prognostic role in breast cancer; however, the prognostic impact of tumor-infiltrating natural killer cells (TINKs) is still not well established. Our aim was to assess the prognostic impact of natural killer (NK) cells in breast carcinomas. MATERIALS AND METHODS: NK cells infiltration were assessed by immunohistochemistry (IHC). Statistical analyses were performed to evaluate the correlation of NK cells with clinical-pathological features and outcome. RESULTS: CD56 IHC was realized in 126 patients. NK cells infiltration showed significant and positive association with tumor high Scarff-Bloom-Richardson (SBR) grade. NK cells were significantly associated with HER2-positive breast cancer and triple-negative breast cancer subtypes. Analyses showed significant and inverse correlation with progesterone and estrogen receptors expression status. High NK cells were significantly related to high Ki-67 labeling index. Our data showed that high NK cells infiltrate was significantly associated with tumor-infiltrating lymphocytes in breast cancer tissues. At a median follow-up of 5.5 years, high CD56 expression (≥ 5 cells/10 high power field) was associated significantly with a good overall survival and with good disease-free survival. CONCLUSION: In this study, we assessed the important prognostic role of TINKs in breast carcinomas, which seems to be evident despite its association with aggressive pathological features. Thus evaluation of NK cells can be standardized and integrated in daily routine.

INTRODUCTION: Miscarriage is one of the most common adverse pregnancy outcomes. The aim of this study was to investigate the relationship between miscarriage in humans and infections caused by zoonotic bacteria and genital pathogens. METHODOLOGY: Cervicovaginal swabs and placenta samples from 132 women with miscarriage (patient group: PG), and cervicovaginal swabs from 54 women with normal pregnancy (control group:CG), were subjected to bacteriological culture and real time PCRs detecting Coxiella burnetii, Brucella spp, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, Chlamydia trachomatis, Waddlia chondrophila and Parachlamydia acanthamoebeae DNA. Serology of C. burnetii, C. trachomatis and W. chondrophila was also performed. RESULTS: Placenta samples were positive for E. coli, S. agalactiae, U. urealyticum, M. hominis and C. trachomatis in 4.7%, 3.1%, 3.1%, 0.7% and 0.7% of cases, respectively. For cervicovaginal swabs, M. hominis was more frequently detected among PG than CG with a significant statistical difference (p = 0.02). C. trachomatis was detected in 3.3% and 5.5% among PG and CG, respectively. U. urealyticum DNA was detected with high percentages in the two groups. Samples from both groups showed negatives results for C. burnetii, Waddlia, and Brucella qPCRs. A high rate of W. chondrophila seroprevalence (42%) was noted with significant difference among women with early miscarriage. CONCLUSIONS: C. trachomatis, S. agalactiae and M. hominis may play a role in miscarriage. However, the full characterization of the vaginal flora using other technologies such as NGS-based metagenomics is needed to clarify their role in miscarriage. Finally, further investigations should be performed to explain high W. chondrophila seroprevalence.

OBJECTIVE: To describe for the first time the epidemiologic and clinico-pathologic characteristics of vulvar cancer in Tunisia. DESIGN: Two parts are distinguished in this study: Part1: Multicentric retrospective study about the characteristics of all cancer cases diagnosed during a 17-years period (January 1998-December 2014) in three departments of Gynecology and Obstetrics: one in south Tunisia and two in the capital. Part 2: To determine the Incidence trend of invasive vulvar cancer in North Tunisia 1994-2009, on the basis of North Cancer Registry of Tunisia. RESULTS: A total of 76 cases of vulvar cancer were recorded. The median age at diagnosis was 65.4years and 86.9% of patients were more than 55years old. The symptomatology was dominated by vulvar pruritus in 48.7%. The average size of the tumor was 3.96cm. Stage III was the most frequent (53.7%) followed by stage II (28.3%). Only 10.4% of tumors were at stage I. The most common histologic type of vulvar malignancy was squamous cell carcinoma (SCC) (94.7%). Standardized incidence varied from 1.2/100 000 (1994) to 0.5/100 000 (2009). There was significant decrease of Standardized incidence (APC of -8.8% per year, 95% CI: -5.5%, -9.0%-p<0.001). CONCLUSION: Vulvar cancer in Tunisia is a rare disease, occurs mostly in elderly women, and is diagnosed at advanced stages. Our findings emphasize that a greater effort should be made to facilitate early diagnosis, as treatment in earlier stages is less extensive and potentially curative.

BACKGROUND: Fetal macrosomia is associated with an increased risk of adverse outcomes to both the mother and the infant. AIM: To determine maternal and neonatal outcomes associated to fetal macrosomia in diabetic and non- diabetic mothers. METHODS: It is a descriptive retrospective study conducted in Tunisia. We included in this study all patients who delivered newborns having a birth weight above 4kg during 2013. Multivariate analysis was performed using binary logistic regression to identify the complications associated to macrosomic pregnancies with diabetes. RESULTS: Among the 10186 deliveries registered during the study period, 821 mothers gave birth to macrosomic newborns. The prevalence of macrosomia was 8.1%, and macrosomic newborns who had a birth weight of 4500 g or greater were 1.06%. Macrosomia was significantly higher in males (p <10-3). The rate of cesarean delivery was 47.9%. The most frequent adverse maternal and neonatal outcomes were perineal tears (3.6%), post-partum hemorrhage (0.6%), shoulder dystocia (4.9%) and neonatal intensive care unit admission (7.6%).The proportion of maternal diabetes was 9.3%. Macrosomic pregnancies with diabetes appear to be significantly associated with cesarean delivery (OR=2.22), postpartum hemorrhage (OR=6.69) and neonatal intensive care unit admission (OR=4.18). CONCLUSION: Macrosomia increases the risk of maternal and perinatal morbidity particularly when it was associated to maternal diabetes.

Background Although Oxytocin is used systematically during caesarean section, no recommendation precise optimal dose for this indication. The bolus administration of 10 IU intravenously after extraction of the newborn, is accompanied by side effects mainly hemodynamic. Objectives To compare two Oxytocin protocols:  05 IU bolus Vs. 10 IU bolus during Cesarean section by studying their respective effectiveness (effects on uterine tone) and adverse effects. Methods A prospective randomized double-blind study including 87 term parturients for undergoing a C-section under loco regional anesthesia. Parturients were randomized into two groups depending on the injected Oxytocine dose : - Group 1 (n = 43): 10 IU + 25 IU IVD in 500 ml of serum / 3h - Group 2 (n = 44): 5 IU IVD + 25 IU in 500 ml serum / 3h. Results The variation of the heart rate and the incidence of low blood pressure were significantly greater for Group 1. No significant differences between the two groups regarding blood loss was noticed per or postoperatively. The type of digestive side effects were more common in the first group. Conclusion Administration of 5 units of Oxytocin during the scheduled C-sections is effective for uterine tone without superimposed bleeding risk, guarantees better hemodynamic stability and less side effects than the 10 units dose.
