Intramural ectopic pregnancy: An individual patient data systematic review.

Intramural pregnancies (IMP) are very rare and represent about 1% of ectopic pregnancies (EPs). Despite a few reported cases, there is limited awareness & knowledge among sonographers and physicians. Moreover, no established diagnostic or treatment protocol exists for such a condition. This study identifies and synthesizes what is known about IMP, including etiology and pathophysiology, common clinical presentations, imaging features, laparoscopic and hysteroscopic findings, and management. PUBMED and Google Scholar were queried to identify eligible studies. All articles on IMP in human subjects available in English and French languages were included. Other types of ectopic pregnancies, including cesarean scar and cervical ectopic pregnancies, were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines and a narrative synthesis approach were used to systematically review the medical literature. 82 cases distributed around 27 countries with an average maternal age of 32.07 years and gestational age of 9.27 weeks were eventually selected for this study. History of curettage was the most common risk factor reported in 30 (36.58%) patients, followed by history of salpingectomy, assisted reproduction with embryo transfer, and previous cesarean delivery, in 10(12.19%), 10(12.19%), and 9(10.97%) patients respectively. Ultrasound was performed in 80(97.56%) cases. Of the 66 reported ultrasound findings, 29 were diagnostic or suggestive of IMP. MRI, laparoscopy (both diagnostic & surgical) and diagnostic hysteroscopy were carried out on 18(21.95%), 36(43.9%) and 22(26.83%) patients respectively. Histopathologic examination mainly performed after surgery was the gold standard for confirming the diagnosis. Management involved conservative (3.65%) approach, medical treatment with methotrexate or potassium chloride (23.17%), and surgical interventions. The latter includes laparoscopic surgery (25.61%), laparotomic surgery (23.17%), and hysterectomy (13.41%). IMP is a rare but potentially lethal clinical entity. A significant proportion of patients are asymptomatic and have no known risk factors. Correlation between clinical history and imaging findings is vital to establish a prompt diagnosis and reduce the risk of a catastrophic outcome.

Race, age, and sex differences on the influence of obesity on colorectal cancer sidedness and mortality: A national cross-sectional study.

BACKGROUND AND OBJECTIVES: Colorectal cancer (CRC) sidedness is recognized as a prognostic factor for survival; left-sided colorectal cancer is associated with better outcomes than right-sided colon cancer (RsCC). We aimed to evaluate the influence of obesity on CRC sidedness and determine how race, age, and sex affect mortality among overweight and obese individuals. METHODS: A survey-weighted analysis was conducted using data obtained from the National Inpatient Sample between 2016 and 2019. RESULTS: Of the 24 549 patients with a diagnosis of CRC and a reported body mass index (BMI), 13.6% were overweight and 49.9% were obese. The race distribution was predominantly non-Hispanic Whites (69.7%), followed by Black (15.6%), Hispanic (8.7%), and other race (6.1%). Overweight (BMI: 25-29.9) and obese (BMI: ≥30) individuals were more likely to have RsCC (adjusted OR [aOR] = 1.28; 95% CI: 1.17-1.39, p < 0.001 and aOR = 1.45; 95% CI: 1.37-1.54, p < 0.001, respectively). Obese Black individuals were more likely to have RsCC as compared to their White counterparts (aOR = 1.23; 95% CI: 1.09-1.38). CONCLUSIONS: Obesity is associated with an increased risk of RsCC. In addition, racial disparities in CRC sidedness and outcomes are most pronounced among obese patients.

Pancreatic schwannoma: Case report, clinico-pathologic correlation, and review of the literature.

Schwannomas are common peripheral nerve sheath tumors that typically occur on the head, neck, trunk, or extremities. Intra-abdominal schwannomas, however, are rare. We describe a young woman who presented for imaging evaluation of suspected nephrolithiasis and was incidentally found to have a schwannoma centered within the pancreatic parenchyma. In addition, we detail the clinical, imaging, and histopathologic features of pancreatic schwannoma and summarize diagnosis and management of this rare clinical entity.

Incarcerated gravid uterus: A rare but potentially devastating obstetric complication.

Incarceration of the gravid uterus is a rare obstetric complication characterized by entrapment of the gravid uterus between the sacral promontory and pubic symphysis. Clinical symptoms are highly variable and may include low back pain, urinary retention, and nausea. A presumptive diagnosis can often be established based on correlation of clinical history and physical examination. However, ultrasound and/or pelvic magnetic resonance imaging are essential for confirmation. Herein, we describe a 30-year-old female who presented with uterine incarceration and discuss the diagnosis, imaging features, and management of this uncommon but important clinical entity.
