OBJECTIVE: The incidence of congenital hypothyroidism (CH) detected by newborn screening in the US has increased significantly since the early 1990s. We defined the characteristics associated with the increased incidence. PATIENTS: A cohort of children with CH born during an earlier period of low incidence (1991-94) was compared with a cohort born during a later period when the incidence of CH had doubled (2001-04). MEASUREMENTS: Screening was performed with T4 as the primary marker and thyroid stimulating hormone (TSH) on selected specimens. Follow-up on hypothyroid children determined whether they had permanent or transient hypothyroidism. Cases were classified based on laboratory …

BACKGROUND: Animal studies have demonstrated that timing of pubertal onset can be altered by prenatal exposure to dioxins or polychlorinated biphenyls (PCBs), but studies of human populations have been quite limited.

METHODS: We assessed the association between maternal serum concentrations of dioxins and PCBs and the sons' age of pubertal onset in a prospective cohort of 489 mother-son pairs from Chapaevsk, Russia, a town contaminated with these chemicals during past industrial activity. The boys were recruited at ages 8 to 9 years, and 4 years of annual follow-up data were included in the analysis. Serum samples were collected at enrollment …

BACKGROUND: Few studies have investigated reproductive health effects of contemporary agricultural pesticides in boys. OBJECTIVES: To determine the association between pesticide exposure and reproductive health of boys. METHODS: We conducted a cross-sectional study in rural South Africa of boys living on and off farms. The study included a questionnaire (demographics, general and reproductive health, phyto-estrogen intake, residential history, pesticide exposures, exposures during pregnancy); and a physical examination that included sexual maturity development ratings; testicular volume; height, weight, body mass index; and sex hormone concentrations. RESULTS: Among the 269 boys recruited into the study, 177 (65.8%) were categorized as farm (high …

Comparison Of Insulin Infusion Protocols Targeting 110-140 Mg/Dl In Patients After Cardiac Surgery., Vasudev Magaji, Shriddha Nayak, Amy Donihi, Lauren Willard, Srinivasa Jampana, Parachur Nivedita, Raymond Eder, Jann Johnston, Mary Korytkowski

Vasudev G Magaji MD, MS

BACKGROUND: Continuous intravenous insulin infusion (CII) following coronary artery bypass graft (CABG) surgery reduces postoperative complications and hospitalization duration. Because of limited data evaluating outcomes of CII with revised glycemic targets (110-140 mg/dL) in cardiac surgery, this study compared efficacy and safety of two different CII protocols having revised targets. SUBJECTS AND METHODS: This is a retrospective study comparing two different protocols between August 2009 and March 2010. Protocol 1 consists of four algorithms, and Protocol 2 is a table to adjust CII. Blood glucose (BG) and CII rates were recorded for 48 h postoperatively or CII discontinuation. Efficacy was …
