Endemic goitre Endemic goitre Endemic goiter is a type of goitre that is associated with dietary iodine deficiency. Some inland areas where soil and water lacks in iodine compounds and consumption of marine foods is low are known for higher incidence of goitre. In such areas goitre is said to be "endemic". This type of goiter is easily preventable. In most developed countries regulations have been put into force by health policy institutions requiring salt, flour or water to be fortified with iodine. Treatment of endemic goiter is medical with iodine and thyroxine preparations. Surgery is only necessary in cases where complicated
Mitochondrial trifunctional protein deficiency mitochondrial trifunctional protein deficiency that may begin "after" infancy include hypotonia, muscle pain, a breakdown of muscle tissue, and a loss of sensation in the extremities called peripheral neuropathy. Some who have MTP deficiency show a progressive course associated with myopathy, and recurrent rhabdomyolysis. The genetics of mitochondrial trifunctional protein deficiency is based on mutations in the HADHA and HADHB genes which cause this disorder. These genes each provide instructions for making part of an enzyme complex called mitochondrial trifunctional protein. This enzyme complex functions in mitochondria, the energy-producing centers within cells: mitochondrial trifunctional protein contains three enzymes that each
