background beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. the purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. materials and methods this descriptive-cross sectional study was performed on 90 children aged 6-16 yea...
BACKGROUND Statins, such as simvastatin, are the drugs of choice for the treatment of hypercholesterolemia. On the other hand hypercholesterolmia can occur in hypothyroid patients, who receive levothyroxine. There are few clinical case reports in regards to drug interaction between levothyroxine and lovastatin or simvastatin, indicating decreased levothyroxine effects. This study aimed at deter...
BACKGROUND The effects of lead exposure on thyroid function are unclear. METHODS Serum thyroxine (T4) was evaluated among 137 lead-exposed workers and 83 non-exposed workers. Free thyroxine (FT4) was evaluated among a subset of these workers. Exposure metrics included blood lead level (BLL), which reflects recent exposure, zinc protoporphyrin (ZPP), a marker of intermediate-duration lead expo...

Abstract Introduction The African Copperbelt is a site of intense artisanal and industrial mining refining copper cobalt. Based on preliminary case-control study erectile dysfunction among mineworkers in the former Katanga province Democratic Republic Congo (Musa et al. Occupational Environmental Medicine 2020), Objective We further investigated possible factors associated with cobalt miners pr...
We describe a new double-antibody enzyme radioimmunoassay for thyroxin-binding globulin (TBG) in serum. A TBG-beta-D-galactosidase complex was prepared with m-maleimidobenzoyl N-hydroxysuccinimide ester. The mean analytical recovery of TBG added to serum was 99%, sample volume and TBG value were linearly related, and values for TBG determined by this method and those determined by radioimmunoas...

BACKGROUND AND PURPOSE Low level of thyroid hormone is a strong independent risk factor for white matter (WM) injury, a major cause of cerebral palsy, in preterm infants. Thyroxin upregulates brain-derived neurotrophic factor during development. We hypothesized that thyroxin protected against preoligodendrocyte apoptosis and WM injury in the immature brain via upregulation of brain-derived neur...
Continued administration of large doses of thyroid may not produce hyperthyroidism in euthyroid individuals. Cessation of prolonged high-dosage thyroid replacement can cause transient clinical and biochemical hypothyroidism owing to pituitary suppression. A case is recorded in which both these phenomena are well demonstrated. This case highlights these basic endocrinological principles.
