Fibrosis in Hepatitis C Patients Predicts Complications After Elective Total Joint Arthroplasty

Effects of Hepatitis C on total hip (THA) and total knee arthroplasty (TKA) outcomes are poorly understood. Seventy-two hepatitis C patients underwent 77 primary THA or TKA and were retrospectively identified, stratified by fibrosis and thrombocytopenia and compared to matched controls. Overall, Hepatitis C and control patients had similar outcomes. After TKA, fibrotic hepatitis C patients demonstrated a greater average hemoglobin drop than non-fibrotic hepatitis C patients (4.9 versus 3.8, P = 0.023), greater deep infection rate (21% versus 0%, P = 0.047), and rate of cellulitis (21% versus 0%, P = 0.047). Thrombocytopenia showed a trend toward greater infections. Prior to fibrosis, Hepatitis C patients appear to be at no increased risk of complication after joint arthroplasty. Evaluation of fibrosis may predict poor outcome in Hepatitis C patients.     

Rupture of the primigravid uterus: a review of the literature

Uterine rupture is a catastrophic obstetric complication, associated with high rates of perinatal morbidity and mortality. The most common risk factor is previous uterine surgery, and most cases of uterine rupture occur in women with a previous cesarean delivery. Traditionally, the primigravid uterus has been considered almost immune to spontaneous rupture. In fact, although spontaneous rupture of the primigravid uterus is indeed a very rare event, a number of such cases have been reported recently. Prompt recognition of uterine rupture and expeditious recourse to laparotomy are critical in influencing perinatal and maternal morbidity. Not all uterine ruptures present with the typical clinical picture of abdominal pain, hypovolemia, vaginal bleeding, and fetal compromise. Therefore, it is important to maintain a high index of suspicion for uterine rupture in women presenting with some, or all, of these features, regardless of parity. Here we provide a systematic review of cases of spontaneous uterine rupture in primigravid women reported in the literature to date. Clinical presentation, differential diagnosis, common etiological factors, complication rates, and appropriate management of this rare obstetric event are discussed. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to recall that uterine rupture in a primigravida is a rare event, without typical signs and symptoms, and explain that the morbidity and mortality of the mother and child is directly related to a high index of suspicion and prompt treatment by the clinician.     

Bilateral luteomas of pregnancy in a patient with diabetes

A patient with diabetes and luteomas of the ovaries demonstrated a significant and progressive rise in the serum levels of androstenedione and testosterone during pregnancy. The levels of these hormones were also elevated in cord blood and ovarian fluid. The increased insulin requirement to maintain euglycemia was observed at an earlier date in this pregnancy than in her previous pregnancy.     

Fetal heart rate characteristics that provide confidence in the diagnosis of fetal well-being

Fetal heart rate monitoring was first used as a clinical tool for the assessment of fetal danger and well-being. In the past decade, basic research has demonstrated the physiologic events associated with most heart rate changes. This review has demonstrated that study and semiquantification of the five analyzable features of an FHR recording can provide a strong reassurance of fetal health. The method has not proven as predictable for defining fetal disease, so additional parameters are needed to define clearly the significance of an abnormal FHR tracing.
