Diagnosis and management of a pelvic solitary fibrous tumor in a postmenopausal woman - a case report.

Background: Solitary fibrous tumors, previously known as hemangiopericytomas, originate from mesenchymal tissue and can occur at many body sites, such as the thorax, head and neck, retroperitoneal space and abdomen. These tumors are generally rare and pelvic location is extremely uncommon. Consequently, pelvic solitary tumors could be mistaken for ovarian cancer in menopausal women. This report presents a case of pelvic solitary tumor to highlight the importance of considering this diagnosis in a postmenopausal woman presenting with a solid pelvic mass, normal tumor markers and no ascites. Case: A 54-year-old woman presented with amenorrhea, abdominal pain, constipation, nausea, vomiting, and frequency of urination. On examination she had a pelvic mass of approximately 20-24 weeks in size. Ultrasound and computed tomography imaging showed a well-defined, round, centrally hypodense, irregular thick and peripheral, enhancing solid mass originating from the left ovary. Carcinoembryonic antigen, carbohydrate antigen-125, and carcinoembryonic antigen 19-9 were all normal. Intraoperatively the tumor was attached to the peritoneum and mesentery. Part of the large bowel, including the sigmoid colon, were attached to it. The exact origin of the tumor could not be ascertained during surgery. The tumor was successfully excised, and specimen sent for histology and immunochemistry analysis. The definitive diagnosis was confirmed with immunochemistry. The patient had an uneventful postsurgical course and was discharged on day 4 after surgery for routine gynecological follow-up. Conclusion: Solitary fibrous tumor is very rare; however, the diagnosis should be considered in a postmenopausal woman with solid pelvic mass, normal tumor markers and no ascites.

The role of the placenta in perinatal asphyxia, neonatal encephalopathy, and neurodevelopmental outcome: A review.

Perinatal asphyxia contributes significantly to neonatal deaths globally. This may occur due to the effects of various phenomena like uterine rupture, infections, maternal hemodynamic compromise (amniotic fluid embolus), placenta, and umbilical cord (umbilical cord knot, placental abruption, or compression). Perinatal asphyxia is the term used for interrupted blood flow or the exchange of gases in the fetus during the prenatal period. The reduced oxygenation induces a cascade of brain injuries, resulting in long-term damage to the infant's brain. Some infants exposed to perinatal hypoxia-ischemia will make an immediate recovery and have normal survival, while others may suffer from an evolving clinical encephalopathy. This review article focuses on the relationship between the placenta, neonatal encephalopathy, and neurodevelopmental outcome. It also aims to identify possible interventions and drive the focus of policymakers towards issues that evolve around perinatal asphyxia, neonatal encephalopathy, and neonatal care and that have a high impact on infant morbidity in sub-Saharan Africa.

Role of genetic factors in recurrent miscarriages - A review.

Recurrent miscarriage is classically defined as three or more consecutive pregnancy losses in about 1-5% of couples trying to conceive. However, several researchers have amended this to two or more because of the recent increase in childless miscarriages. Recurrent miscarriage is a clinical challenge for clinicians because there are many possible causes, and diagnostic testing is expensive and time-consuming. Established causes of recurrent miscarriage are antiphospholipid antibodies, uterine anomalies, and abnormal chromosomes in either partner, particularly translocations. Uterine anatomical abnormalities, endocrine abnormalities, infections, immunologic factors, environmental factors, metabolic or hormonal disorders, sperm quality, and maternal and paternal age have each been linked. Among them, the genetic factor plays a significant role in recurrent miscarriage. Approximately 70% of miscarriage conceptions with sporadic spontaneous miscarriage reveal some chromosome abnormality. Specifically, recurrent miscarriage can be caused by a structural or numerical defect in the parents' or fetus' chromosomes. Recurrent miscarriage has been linked to several genes, including those involved in oxidative stress, angiogenesis, clotting, and inflammation. Despite several well-known etiologic factors, the etiology of recurrent miscarriage is unknown in over half of all instances. The current review aims to analyse the role of the genetic basis of recurrent miscarriages.

"Suction Tube Uterine Tamponade" for treatment of refractory postpartum hemorrhage: Internal feasibility and acceptability pilot of a randomized clinical trial.

OBJECTIVE: To assess feasibility and acceptability of a novel, low-cost "Suction Tube Uterine Tamponade" (STUT) treatment for refractory postpartum hemorrhage (PPH). METHODS: We allocated patients with refractory PPH by randomly ordered envelopes to STUT or routine uterine balloon tamponade (UBT, Ellavi free-flow system) in 10 hospitals in South Africa. In the STUT group, a 24FG Levin stomach tube was inserted into the uterine cavity and vacuum created with a vacuum pump or manual vacuum aspiration syringe. RESULTS: For this internal pilot study, 12 participants were allocated to STUT and 12 to UBT. Insertion failed in one of each group and was recorded as difficult in 3/10 STUT and 4/9 UBT insertions respectively (five missing data). There were two laparotomies and one intensive care unit admission in the UBT group. Pain during STUT insertion was graded as none/mild in 9/10 and severe in 1/10. The experience of the STUT procedure was graded as fine in 4/11 and "uncomfortable but acceptable" in 7/11. CONCLUSION: STUT is feasible and acceptable, justifying continuation of our trial. These data will also inform a large World Health Organization trial to test effectiveness of uterine tamponade methods. The numbers are too small to support any clinical recommendation.

Maternal characteristics and pregnancy outcomes of hospitalized pregnant women with SARS-CoV-2 infection in South Africa: An International Network of Obstetric Survey Systems-based cohort study.

OBJECTIVE: To describe risk factors and outcomes of pregnant women infected with SARS-CoV-2 admitted to South African healthcare facilities. METHODS: A population-based cohort study was conducted utilizing an amended International Obstetric Surveillance System protocol. Data on pregnant women with SARS-CoV-2 infection, hospitalized between April 14, 2020, and November 24, 2020, were analyzed. RESULTS: A total of 36 hospitals submitted data on 673 infected hospitalized pregnant women; 217 (32.2%) were admitted for COVID-19 illness and 456 for other indications. There were 39 deaths with a case fatality rate of 6.3%: 32 (14.7%) deaths occurred in women admitted for COVID-19 illness compared to 7 (1.8%) in women admitted for other indications. Of the women, 106 (15.9%) required critical care. Maternal tuberculosis, but not HIV co-infection or other co-morbidities, was associated with admission for COVID-19 illness. Rates of cesarean delivery did not differ significantly between women admitted for COVID-19 and those admitted for other indications. There were 179 (35.4%) preterm births, 25 (4.7%) stillbirths, 12 (2.3%) neonatal deaths, and 162 (30.8%) neonatal admissions. Neonatal outcomes did not differ significantly from those of infected women admitted for other indications. CONCLUSION: The maternal mortality rate was high among women admitted with SARS-CoV-2 infection and higher in women admitted primarily for COVID-19 illness with tuberculosis being the only co-morbidity associated with admission.
