1. A dialectal name “Shibi-Gatchaki” represents a syndrome, which is very commonly found among the inhabitants of Tsugaru district of Aomori Prefecture.
2. This syndrome can probably be ascribed to a chronic malnutrition, especially a deficiency in vitamin B2 complex, without serious detriment to labour, reproduction and growth. It is characterized by pellagrous skin lesions, ariboflavinotic signs, and a distressing itching of anal and genital regions.
3. The fact that such a special term “Shibi-Gatchaki”, has been given to the syndrome in question by the inhabitants of this district, suggests that this syndrome is endemic to this area, and has been existed for a considerable period of time in this area.
4. The chief cause was found to be due to a nutritional deficiency, by ingesting a monotonous and inadequate diet based on an one-sided overeating habit of polished rice with insufficient ingesting of essential nutrients.
