Iodine deficiency Iodine deficiency Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in a goiter, sometimes as an endemic goiter as well as cretinism due to untreated congenital hypothyroidism, which results in developmental delays and other health problems. Iodine deficiency is an important public health issue as it is a preventable cause of intellectual disability. Iodine is an essential dietary mineral; the thyroid hormones thyroxine and triiodothyronine contain iodine. In areas where there is little iodine in the diet, typically remote inland areas where no marine foods are eaten, iodine deficiency
Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde (MIF) is a solution used in biomedical laboratories for concentration of stool samples prior to microscopic investigation for parasites. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non-concentrated samples the likelihood of finding equivalents of actually present parasites is too low. MIF enables separation of different strata of stool matter, and sedimentation of stool particles that contain parasites (usually parasite eggs). After application of MIF, usually centrifugation is used for acceleration of sedimentation. The term "Merthiolate" indicates presence of thiomersal in the solution. Due to the hazardous qualities of thiomersal, it is
