Olfactory bulbectomy (OBX) in rats produces behavioral, physiological, and neurochemical changes that resemble symptoms of depression in humans. The procedure thus serves as a rodent model of affective disorder. Many of the behavioral effects of OBX resemble psychomotor agitation. The possible role of dysregulation of ventral striatal dopamine (DA) systems(More)
OBJECTIVE To evaluate the influence of 2 continuous combined estrogen-progestin replacement products, compared with unopposed estrogen and placebo, on cardiovascular risk markers in postmenopausal women in a randomized, double-blind, placebo-controlled trial. METHODS Two hundred seventy healthy postmenopausal women were randomly assigned to 1 of 4(More)
PURPOSE Endothelin-1, prostaglandins (PGs), and nitric oxide (NO) have been implicated in the intestinal microvascular dysfunction of necrotizing enterocolitis (NEC). We hypothesized that direct peritoneal resuscitation (DPR) dilates the intestinal microvasculature and improves blood flow independent of these mechanisms. METHODS Rat pups were assigned by(More)
Vasoconstriction of the neonatal intestinal microvasculature is a central mechanistic event in development of necrotizing enterocolitis. We hypothesized that topical treatment of the intestine with dialysate fluid would ameliorate the vasoconstriction in necrotizing enterocolitis (NEC). NEC was induced in experimental groups. Control animals were delivered(More)
BACKGROUND The maternal variables that affect fetal development and correlate with necrotizing enterocolitis (NEC), the most common gastrointestinal emergency in premature infants, are not well defined. We hypothesized that maternal risk factors were the primary determinant of future development of NEC. METHODS Patients with NEC were identified from an(More)
PURPOSE The spectrum of pediatric biliary tract disease is changing. The goal of this study was to examine the causes and comorbidities of pediatric gallbladder disease at our institution. METHODS We performed a retrospective chart review on consecutive patient at Kosair Children's Hospital who underwent cholecystectomy over a 9-year time period ending in(More)
A predominance of small, dense low-density lipoprotein (LDL) particles (subclass pattern B) has been associated with a 2- to threefold increase in coronary heart disease risk. Recently, it has been reported that LDL subclass pattern B is associated with hyperfibrinogenemia, which is also a coronary heart disease risk factor. The present study examined the(More)
We present a case of a left-sided neck mass in an 8-year-old female that proved to be ectopic thyroid tissue. After excision, this patient continues to do well and is euthyroid without recurrence after 8-year follow-up. This is a very rare anomaly in a child, especially in conjunction with a normally located thyroid that is functional. We reviewed the(More)
OBJECTIVE A predominance of small, dense low-density lipoprotein (LDL) particles (subclass pattern B) is associated with increased risk for coronary heart disease and is characterized by elevated triglycerides and depressed high-density lipoprotein (HDL) cholesterol concentrations. The present analysis was undertaken to assess the impact of LDL subclass(More)
