Thus, the aim of the present study was to assess the probable risk factors associated with PFDs in Iran. Materials and Methods: This cross-sectional study was conducted in two state and private hospitals in Tabriz, Iran from the 1st of June to the 31st of August, 2018. The participants were 650 postpartum women, aged between 15 and 47 years six months after delivery. The type of delivery, type of hospital, history of episiotomy and induction, anesthesia, multiparity, the mother’s birth age, the infant’s weight and head circumference, the mother’s weight gain during pregnancy, and a wide variety of probably related risk factors were studied based on the study objective. According to their answer to the questions of PFDs, 147 women responded yes and completed the Pelvic Floor Distress Inventory-20 questionnaire. Results: Between the investigated risk factors, type of the hospital (OR: 0.27, CI: 0.126-0.564) and the amount of the mother’s weight gain during pregnancy (OR: 1.066, CI: 1.024-1.109) were significantly associated with PFDs. Finally, the number of PFDs and severity of dysfunctions according to PFDI-20 were higher in state hospitals, and excessive weight gain of the mother during pregnancy was related to the higher incidence of PFDs. Conclusions: Type of the hospital and the mother’s weight gain during pregnancy are the only two related risk factors in this study. This study was the first one to discuss the type of the hospital in such related risk factor studies. Accordingly, it is predictable that better supervision of medical attends in state hospitals is highly important for decreasing the rate of PFDs after delivery.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"11 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78359445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of the study are to determine and compare the histopathology, biomarkers, and development of endometrial lesions in murine homologous and heterologous endometriosis models. Methods: The literature search was performed on PubMed, Scopus, Web Cochrane, and EMBASE from January 1990 to January 2019. Experimental articles in which the establishment of the endometriosis model had been proven through the examination of size, weight, number of implants, adhesion, histologic score, and altered biomarker were eligible for inclusion. Results: Based on type of induction, articles were categorized into two groups: heterologous-induced method (n=5) and autologousinduced method (n=13). In general, in case of establishing the heterologous induction method is less reliable than the autologous induction method. Conclusions: Using human endometrial tissues for endometrial inductions is possible in heterologous models under immunosuppression, which is more suitable for therapeutic studies, but time limitation considerations are mandatory for this type of model. Homologous endometriosis inductions cause larger endometrial lesions, biomarkers, and reproduction rate changes similar to those occurring in humans. Similarities make this method more appropriate for pathogenesis and genetic studies and also observe the impact of endometriosis on the next generation. Choosing an appropriate model for the induction of endometriosis is dependent on the purpose of each study.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90944936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the uterine perfusion during the follicular phase in patients with a history of recurrent implantation failure (RIF) and healthy fertile women using the transvaginal ultrasound color Doppler method. Materials and Methods: To this end, 50 patients with RIF and 50 age-matched healthy fertile women were recruited in this case-control study. The transvaginal color Doppler ultrasonography was used to evaluate the pulsatility index (PI) and resistance index (RI) of the uterine, arcuate, and sub-endometrial arteries during the follicular phase in both groups. Results: The RI and PI of both right and left uterine arteries were higher in the RIF group compared to the fertile women (P<0.05). Our results showed that the PI and RI of sub-endometrial blood flow and the RI of arcuate arteries were substantially higher in the group with a history of RIF in comparison with the control group. However, the PI of arcuate arteries was not significantly different between the groups. Conclusions: Adequate uterine perfusion and sub-endometrial blood flow are necessary to achieve successful implantation and pregnancy since our results demonstrated the higher resistance of uterine and sub-endometrial arteries in patients with a history of RIF. Thus, the assessments of uterine perfusion indices during the follicular phase could be used as a non-invasive method in the evaluation of patients with RIF.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"12 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86058414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is rarely observed after a cesarean section or a gynecological surgery involving the uterus. The presence of an infection further complicates the management. In countries such as India where tuberculosis is highly prevalent, Mycobacterium tuberculosis should be ruled out. Case Presentation: A 29-year-old nulliparous woman who had undergone a laparotomy for removal of a large fibroid for primary infertility presented with complaints of abdominal pain and discharge from the scar site. These symptoms did not resolve with antibiotics and analgesics. An ultrasonography was performed and a fistulous tract extending up to the endometrium was revealed. She underwent a laparoscopic resection of the fistulous tract following which she was symptom free. Conclusion: One of the rarely observed complications following laparotomies and cesarean section is a uterocutaneous fistula. It is even rarer in women with no previous pregnancies. The management involves adhesiolysis and layer by layer closure of the uterus and abdomen wall after excising the tract. Most often a repeat laparotomy is performed to treat the condition, but in the current times it is well known that repeated open surgeries in the peritoneal cavity increase the chances of adhesions which can reduce the chances of pregnancies in nulliparous women. Hence, this article shows a successful outcome of laparoscopic uterocutaneous fistula repair.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"33 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80750771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preeclampsia is the first target to decrease because it is one of the preventable pregnancy complications. Currently, preeclampsia has patterns for treatment from early detection to delivery; therefore, reasonable chances of decreasing the MMR rapidly and significantly should be considered in Indonesia. Materials and Methods: The reasons for choosing preeclampsia for reducing MMR included an early detection method, availability of affordable medication for the prevention of preeclampsia, development of a national guideline for medical practice regarding preeclampsia, establishment of health institutions by government and the private sector in remote areas, and availability of sufficient health personnel. Results: Early detection of risk factors of preeclampsia is of great importance. Recommended preventive medication includes a combination of acetyl salicylic acid and calcium for 12 weeks for a high-risk group. National guidelines for the management of preeclampsia should be distributed to all hospitals including those covered by national health insurance. Conclusions: The goal of zero mother mortality preeclampsia program is to make policies for all health workers and the general public so that the prevention process can take place. Delivery of all cases with hypertension should be performed in the hospital without exception so no delivery should be performed at home without specialist supervision.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"58 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91077707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This group was compared with 18 patients undergoing radical hysterectomy with cervical cancer FIGO stage IIA-IB1 in the same period of time. Results: In the NACT group, 8 (61.5%) and 5 (38.4%) patients were in stages IIB and IB2, respectively, and 13 (72.2%) cases were in the IB1 stage in the non-NACT group. Post-operative blood transfusion in the NACT group was significantly higher compared to the non-NACT group [5 (38.4%) patients versus 0, P = 0.008]. The estimated blood loss (EBL) and operative time were similar between the groups. Finally, there were no significant differences in terms of intra-operative and other post-operative complications.

In this regard, this study proposed an algorithm for CSP management with consecutive outcomes. Materials and Methods: In this randomized clinical trial study, the data of 44 patients with CSP were collected, and the diagnosis was confirmed by transvaginal ultrasonography (TVS). Unstable patients underwent uterine artery embolization (UAE), and the fetal reduction was done for patients with the fetal heart rate (FHR). In addition, patients received systemic methotrexate (MTX) injections according to their beta-human chorionic gonadotropin (β-hCG) levels and then were followed on a predetermined schedule by β-hCG levels and TVS. Finally, prophylactic UAE was considered for patients with ongoing bleeding, placental hypervascularity, and the prospect of limited access to care. Results: Patients were within the age range of 33.9±4.9 years and the gestational age of 7.37±1.57 weeks. Twenty-two patients (50%) had vaginal bleeding, 3 of whom were unstable and underwent UAE. Five patients underwent a total abdominal hysterectomy, and fourteen patients with FHR underwent a fetal reduction. Based on β-hCG levels and changes, and placental vascularity, 4 patients received no treatment. In general, 11, 2, and 9 patients received single, double, and multiple MTX injections. A total of 10 patients underwent both multi-doses of MTX and prophylactic UAE. The median period to reach undetectable β-hCG levels was 7.3 weeks and the median interval to start menstruation was 2.8 weeks. In addition, the pregnancy remnant was resolved 3.6 months after the treatment. On the follow-up, no curettage or hysterectomy was needed and seven patients became pregnant (15.9%), 2 of whom presented recurrent CSP (28.6%).

There are two types of endometrial tissue depositions, namely, pelvic and extrapelvic. The deposition of glands in the ovaries, fallopian tubes, and their associated peritoneum is referred to as pelvic endometriosis. Extra pelvic endometriosis is extremely rare and generally involves the gastrointestinal and urinary tracts. The other involved sites are the lungs, central nervous system, surgical scars, and the skin. Endometriosis is estrogen-dependent, and there are many theories describing its pathogenesis (2). It generally affects 5-10% of women in the third decade of life (3). When glands from the endometrium deposit in the lungs or the pleura, it is called thoracic endometriosis syndrome (TES). It is a rare type of endometriosis characterized by catamenial pneumothorax, hemoptysis, pneumothorax, and pulmonary nodules (4) and is commonly mistaken for tuberculosis endemic in countries such as India. This report describes the scenario of a woman aged 26 years old with endometriosis who was presented with dyspnea, hemoptysis, and chest pain. Case Report A married woman aged 26 years with two previous vaginal births was presented with complaints of hemoptysis, chest pain, and dyspnea for about 4 months which was most severe during menstruation and subsided slowly by day 5 or 6 of the menstrual cycle. There was also a history of dysmenorrhea for the last 3 years although there was no history of fever, loss of weight, or loss of appetite. Her symptoms had initially begun about 8 months after the birth of her second child and the hemoptysis and chest pain had progressively increased over a period of time. Suspecting that she might have contracted pulmonary tuberculosis, she underwent anti-tubercular therapy by a general practitioner 4 months ago although she did not improve symptomatically. Then, she was presented with amenorrhea for about two months. Since she did want to continue with the pregnancy, she requested for the termination of pregnancy and permanent sterilization. On detailed history taking, it was found that during the two months of amenorrhea, hemoptysis had subsided.

It is the most common cancer worldwide, causing extensive mortality and many complications (2-4). The incidence of breast cancer is globally increasing, especially in developing countries. Notably, about 6 million women with breast cancer were globally identified during 2008-2013 (5). More than 255 000 new cases of breast cancer occurred in the United States in 2017. Meanwhile, the annual incidence of breast cancer is 33 cases per 100 000 people in Iran, and the highest rate has occurred in Tehran, Isfahan, Yazd, Markazi, and Fars provinces (6). One of the concerns associated with breast cancer is its experience during pregnancy (7). Pregnancy-associated breast cancer refers to cancer that occurs during pregnancy, breastfeeding, or one year after delivery. It is the second most common cancer in pregnancy, which rarely occurs and does not cause many deaths (8, 9). Diagnostic and therapeutic interventions during this period are implemented with special considerations. Women with breast cancer are clearly at a more advanced stage of the disease during pregnancy and usually have a poorer prognosis (10,11). One of the major challenges in diagnosis and treatment during this period is maintaining a balance in the aggressive care of these patients and appropriate treatments to maintain the health of the fetus/ baby. Given that the occurrence of this cancer during pregnancy can have adverse effects on the health of the mother, the baby, and the fetus, the current study aimed to investigate the factors affecting the incidence of this type of cancer during pregnancy.","PeriodicalId":14346,"journal":{"name":"International Journal of Women's Health and Reproduction Sciences","volume":"53 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78396836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
