Perivascular epithelioid cell tumors (PEComa) in pregnancy with uterine rupture and ongoing abdominal gestation: A case report.

Perivascular epithelioid cell tumors (PEComa) represent a rare family of tumors characterized by distinct histology and immunohistochemistry characteristics. Approximately one-quarter of reported cases are gynecologic in origin and associated pregnancies are rare. We report a case of PEComa in pregnancy with initial undiagnosed presentation at 18 weeks of gestation and subsequent presentation and diagnosis at 30 weeks of gestation. Abdominal pain led to the use of magnetic resonance imaging, which raised concerns about placentation abnormality and abdominal pregnancy. Exploratory laparotomy was notable for a 10 cm by 15 cm posterior uterine defect through which the placenta and amniotic sac containing the fetus were extruded. Placenta-like tissue was noted to be invading through the anterior wall of the uterus, which led to concern regarding placenta percreta. A total abdominal hysterectomy and bilateral salpingectomy were then performed, given the complete loss of normal uterine architecture. Pathology returned with findings of placenta accreta and PEComa. Indolent uterine rupture in the setting of PEComa led to an ongoing viable abdominal pregnancy. Uterine PEComa can masquerade as a placenta and lead to obstetrical complications.

Lipids and Women's Health: Recent Updates and Implications for Practice.

The obstetrician/gynecologist frequently serves as the primary care physician for women. Specialty-specific guidelines vary in screening recommendations for lipid disorders; women's health practitioners often follow recommendations to screen at age 45 in the absence of other risk factors. However, 2013 American College of Cardiology/American Heart Association cholesterol guidelines recommend screening at age 21 to capture those at risk of cardiovascular disease and allow for early intervention with lifestyle and, in the most severe cases, evidence-based statins. We discuss the care of women who primarily benefit from screening: those with familial hypercholesterolemia (FH), those with the metabolic syndrome (MetS) or polycystic ovary syndrome, and those with hypertriglyceridemia. Those with FH have elevated low-density lipoprotein cholesterol from birth and a propensity for premature coronary heart disease. Early recognition of FH can allow risk-reducing interventions, as well as identification of additional affected relatives. Early detection of metabolic variables, such as in the MetS and hypertriglyceridemia, can lead to an enhanced focus on physical activity and heart-healthy diet. Finally, we discuss a practical approach to lipid management and review concerns regarding drug safety. Our objective is to provide a current overview of cardiovascular risk factor optimization that women's health practitioners can use in identifying and/or treating patients at risk for cardiovascular disease and diabetes.

Update on childhood and adolescent immunizations: selected review of US recommendations and literature: part 2.

PURPOSE OF REVIEW: To provide a clinically relevant synopsis of research findings regarding childhood and adolescent vaccines. RECENT FINDINGS: Vaccine coverage is relatively static or improving for the vaccines included in the 2010 annual harmonized immunization schedules. Providers should be reviewing patients' immunization records at each visit to take advantage of any opportunity to administer indicated, age-appropriate vaccines. There have been infectious disease outbreaks among highly immunized populations, although unvaccinated or undervaccinated individuals continue to play large roles in the spread of disease. Infants, many of whom are too young to be vaccinated, continue to bear a large disease burden, which underscores the importance of cocooning and, in some cases, vaccination of pregnant women. Influenza, measles, mumps, and rubella, varicella, hepatitis A, meningococcal conjugate, human papillomavirus, diphtheria and tetanus toxoids and acellular pertussis, and tetanus and diphtheria toxoids and acellular pertussis vaccines are reviewed in this second of two articles. SUMMARY: New research on childhood and adolescent vaccines is anticipated to shape the practice of pediatric providers. Research will continue to provide the science to optimize protection and to promote the health and well being of all children and adolescents.
