We report a case of cryptococcal thyroiditis presenting with hyperthyroidism that evolved through a transient euthyroid phase to hypothyroidism and finally recovered to normal function. This four-phase clinical presentation is similar to that of subacute thyroiditis, and it is unusual in the setting of infectious nonviral thyroiditis. Cryptococcal thyroiditis is rare; only three cases have been...

Congenital Hypothyroidism (CH) is a common preventable cause of mental retardation. The incidence CH 1 in 2500 to 3000 newborns. Most causes are thyroid dysgenesis and dyshormonogenesis. Some disorder like maternal autoantibodies, intake anti medication, iodine deficiency or excess can result transient CH. Common symptoms include decreased activity increased sleep, feeding difficulty, constipat...

Objective: Compliance to levothyroxine treatment in hypothyroidism is compromised by daily schedule, and a weekly dose may be an alternative. Subjects and methods: This was a randomized, crossover study. Fourteen females were assigned to daily or weekly doses of LT4. After six weeks, they switched regimens. Thyroid parameters were measured at baseline, and after 42 and 84 days. Echocardiogram a...

Effect of propylthiouracil (PTU)-induced hypothyroidism during the prepubertal period, at a dose of oneg per kg of the diet, on serum testosterone level and seminal characteristics of Fars indigenous chickens wasstudied. PTU was fed between 7th to 13th weeks of age and semen was collected at weekly intervals, starting at 21st week of age and continued for seven weeks. The effect of PTU treatmen...

Unrecognized congenital hypothyroidism leads to mental retardation. Newborn screening and thyroid therapy started within 2 weeks of age can normalize cognitive development. The primary thyroid-stimulating hormone screening has become standard in many parts of the world. However, newborn thyroid screening is not yet universal in some countries. Initial dosage of 10 to 15 g/kg levothyroxine is re...
