Standard hypothyroid treatment did not restore proper metabolic response to carbohydrate.

Purpose: Hypothyroidism is associated with a lower metabolic rate, impaired glucose tolerance, and increased responsiveness of sympathetic nervous system to glucose ingestion. The Levothyroxine (LT4) monotherapy is the standard treatment for hypothyroidism; however to what extent this treatment restores the patients' metabolism has not been verified. The aim of this study was to test the hypothesis that standard LT4 therapy may not restore proper metabolic response to carbohydrate ingestion.

Doppler imaging of orbital vessels in the assessment of the activity and severity of thyroid-associated orbitopathy.

Patients with symptoms of thyroid-associated orbitopathy are classified on the basis of the clinical activity score (CAS) proposed by Mourits in 1989. Despite its undoubted clinical usefulness, it has several limitations which can decide about the success or failure of the implemented treatment. Numerous reports mention the presence of hemodynamic changes in orbital and bulbar vessels in the course of an orbitopathy called Graves' disease.

Thermogenic effect of glucose in hypothyroid subjects.

The importance of thyroid hormone, catecholamines, and insulin in modification of the thermogenic effect of glucose (TEG) was examined in 34 healthy and 32 hypothyroid subjects. We calculated the energy expenditure at rest and during oral glucose tolerance test. Blood samples for determinations of glucose, plasma insulin, adrenaline (A), and noradrenaline (NA) were collected.

Enteral feeding during indomethacin and ibuprofen treatment of a patent ductus arteriosus.

Objective: To test the hypothesis that infants who are just being introduced to enteral feedings will advance to full enteral nutrition at a faster rate if they receive "trophic" (15 mL/kg/d) enteral feedings while receiving indomethacin or ibuprofen treatment for patent ductus arteriosus.

Study Design: Infants were eligible for the study if they were 23(1/7)-30(6/7) weeks' gestation, weighed 401-1250 g at birth, received maximum enteral volumes ≤60 mL/kg/d, and were about to be treated with indomethacin or ibuprofen. A standardized "feeding advance regimen" and guidelines for managing feeding intolerance were followed at each site (N = 13).

Hypothermia for hypoxic-ischemic encephalopathy.

We are entering an era in which hypothermia will be used in combination with other novel neuroprotective interventions. The targeting of multiple sites in the cascade leading to brain injury may prove to be a more effective treatment strategy after hypoxic-ischemic encephalopathy in newborn infants than hypothermia alone.
