Thyroid hormone synthesis requires the presence of iodide. The sodium iodide symporter (NIS) is a glycoprotein which mediates the active uptake of iodide from the blood stream into the thyroid grand. NIS defects due to SLC5A5 gene mutations are known to cause congenital hypothyroidism (CH). The proposita is a 28-year-old female whose origin is the North Sudan where neonatal screening for CH is not available. She presented with severe constipation and a goiter at the age of 40 days. Laboratory testing confirmed CH and she was started on levothyroxine (L-T4)...

The iodine deficiency disorders (IDD) include a variety of disturbances such as decreased fertility, increased perinatal and infant mortality, impaired physical and intellectual development, mental retardation, cretinism, hypothyroidism, and endemic goiter (EG). The occurrence of the latter is determined by interplay between genetic and environmental factors. The major environmental factor is iodine status that is required for normal thyroid hormone synthesis. However, other factors like intake of micronutrients and goiterogens also have a significant impact...

The indications and methods of parathyroid autotransplantation in children and adults are reviewed, with special emphasis on the methods of immediate transplantation and delayed autotransplantation after cryopreservation. Parathyroid autotransplantation is performed during surgery when all four parathyroid glands have been intentionally resected in parathyroid hyperplasia, or when all four glands were inadvertently damaged during total thyroidectomy, or recurrent neck surgery. When parathyroid damage is suspected during thyroid or extensive neck surgery, cryopreservation of a parathyroid gland is performed...
