We report a case of a male newborn who was evaluated due to persistent jaundice. Evaluation showed hypothyroidism associated with infantile hemangioma of the liver. Euthyroidism and regression of the hepatic hemangiomas were obtained with L-thyroxin and Propranolol treatment. This case emphasizes the importance of screening for hypothyroidism in patients with neonatal hemangiomatosis.

The association between lack of thyroid hormones and cardiac dysfunction has been well described. We report two new cases of patients with dilated cardiomyopathy (DCM), revealing a periphery hypothyroidism and for whom cardiac function significantly improved after L thyroxin substitutive treatment. Our cases highlight the necessity to perform thyroid function testing to investigate the etiology...

In considering factors that might influence measurement of free thyroxin (T4), we evaluated the proportion (%) of T4 that could be stripped from thyroxin-binding globulin (TBG). The percentage of free T4 was measured in serially diluted sera from four normal subjects, four patients with hyperthyroidism or hypothyroidism, four pregnant women, and four malnourished subjects with low TBG. The crit...

Objective The aim of this study was to evaluate the non-genomic action of thyroxin on sperm kinetic and its probable use to improve sperm recovery after applying an enrichment method like “swim-up” in comparison with the available one, pentoxifylline. MaterialsAndMethods This is an experimental study. A total of 50 patients were recruited, followed by infertility consultation. Conventional sper...

Liver function tests, thyroxin and triiodothyronine levels, and hepatic 5’deiodinase and glutathione peroxidase enzyme activities were measured. Triiodothyronine levels in the carbon tetrachloride group and carbon tetrachloride + selenium group were significantly lower than in the control group (P<0.01, P<0.05, respectively). In the carbon tetrachloride + selenium group, the level of triiodothy...

Objective To evaluate, in rat offspring, bone changes induced by excess maternal thyroxin during pregnancy and lactation, and to assess the reversibility of these changes after weaning. Material and methods Twenty Wistar rats were distributed in two groups, hyperthyroid and control, that were treated daily with L-thyroxin (50 mcg/animal) and placebo, respectively. The treatment was initiated se...

CONTEXT Hypothyroidism is more prevalent in the elderly and its symptoms can be confused with other changes due to aging. Doctors caring for the elderly need to be attentive to this diagnostic possibility. This case report case is notable not only because it presents a rare complication of hypothyroidism (kidney failure), but also because patients with chronic kidney failure of any etiology may...

In previous communications, (1, 2, 3, 4, 5) it has been pointed out that two important questions with regard to the nature of thyroid colloid must be answered because they bear upon the normal and pathological physiology of the gland. The first of these is: Does the colloid of " toxic " glands show significant differences from normal or " non-toxic " colloid? The second question is: Does the ac...

This study was designed to determine the effect of increase hyperthyrodisim on some hormones (Triiodothyronine, thyroxin, thyroid stimulating hormone) and biochemical parameters (creatinine, magnesium) 58 sample used in this at age (25-40 years), where samples were divided into two groups a rate 29 per group. The totals as follows: control group, group patients. It measured hormone Triiodothyro...
