Trichology concern and the present nuclear accident crisis.

Sir,

The side effect of the exposure to leaked nuclides from nuclear accident is documented. However, the specific issue in trichology is not well mentioned. Based on the previous famous Chernobyl nuclear crisis, there are some evidences. There is no doubt that exposure can result in the accumulation in the body and hair is an important site where the nuclides are accumulated.[1] Indeed, there are many reports on the accumulation in hairs of animal. However, few reports on the human beings are available. According to the study of Malenchenko et al., the detected level of plutonium in hair of exposed subjects is correlated with its content in the ribs.[1] Protasova et al. concluded that the content in hairs could be used as a biomarker for accumulation in the body.[2] Focusing on the quality of hair of the exposed subjects, the significant reduction of iron content was reported.[2] The problem of hair loss is an important concern in trichology. Hair loss can be seen in addition to other problems after exposure to the radionuclides. In a report on the cases with thyroid problem due to exposure in Chernobyl crisis, the hair loss can be seen in 68%.[3] The correlation between hair loss and impairment of immune status in exposed subjects is also mentioned.[4] Alopecia is classified as an important chronic disorder frequently seen after exposure to ionizing radiation from nuclear crisis.[5] The proper management is required; however, there is limited knowledge on this issue. The trichology concern in the present nuclear accident crisis is important.
