[Necessity of registrar in medical institution]

In our hospital, we are routinely investigating and recording patients with familial thyroid disorders. We found that about 30% of patients with thyroid disease had some relatives with the same disease as a result of the investigation of more than 13,000 patients. Therefore, a registrar is working for research of familial thyroid disease as a specialist in our hospital. The study was conducted on 258 patients with familial nonmedullary thyroid carcinoma (FNMTC). In cooperation with the registrar, the clinical characteristics of FNMTC emerged. Moreover, 15 patients with nonmedullary thyroid carcinomas were newly found among 149 asymptomatic FNMTC relatives (10%) and underwent operation. In this paper, we report the role of the registrar and emphasize the necessity of a registrar.
