Background: Recently, the placement of drains in thyroidectomy has been debated. In this study, we evaluated the efficacy and safety of no placement of drains in hemithyroidectomy. Methods: After obtaining approval from the Institutional Review Board, we started not placing drains during surgery in adult patients who underwent hemithyroidectomy with or without central neck lymph node dissection for benign thyroid nodules or well-differentiated thyroid cancer, with informed consent being obtained. We compared the clinical data of the patients without drain placement (n=19) to the historical data of consecutive patients with a suction drain (n=20). Results: The operative wound and amount and characteristics of the drainage fluid were monitored every 2 h after the operation until the following morning, in addition to monitoring the oxygen saturation and an electrocardiogram. The proportion of patients undergoing cervical lymph node dissection was identical between the groups. The drain was removed on Day 1 after surgery in 19 patients and on Day 2 after surgery in 1 patient. The patients without a drain showed a significantly shorter postoperative hospital stay than those with a drain (4.0 vs. 4.5 days, respectively, p=0.03). No patients in either group experienced postoperative bleeding or seroma or wound infection. Conclusion: The hemithyroidectomy patients without a drain were able to be discharged earlier than those with a drain and without any adverse events, provided they received close monitoring after surgery.

Good oral health is considered essential in maintaining of individual's good overall health. Information on oral problems and the behavior in visiting dentist is important for promoting oral health of the elderly. To elucidate the oral health status of the elderly in rural areas and factors affecting their oral health, we studied 147 people aged 60 years or over in a rural area of Nagasaki prefecture, Japan. We examined the dental status (dentate or edentate) and denture adaptability, and collected the information on socio-demographic variables, habits, chewing ability, visit to dentist for oral problems, self-perceived general health, and self-perceived oral health. About one-third of the subjects (47/147) had poor self-perceived oral health. Most socio-demographic variables were not associated with poor self-perceived oral health. Logistic regression analysis showed that poor chewing ability (odds ratio (OR): 3.4; 95% confidence interval (CI): 1.4-8.7), being dentate (OR: 6.6, 95% CI: 2.2-24.0), inadequate denture adaptability (OR: 3.7; 95% CI: 1.7-8.8), and no visit to dentist for oral problems (OR: 4.8; 95% CI: 1.8-14.2) were significantly associated with poor self-perceived oral health. In rural areas in Japan, adequate dental care and its good accessibility would be important for promoting the oral health in the elderly.

For many years, Nagasaki University, particularly the Atomic Bomb Disease Institute, has been engaged in research regarding the late health effects of radiation exposure in Nagasaki atomic bomb survivors. Since 1991, we have participated in several Chernobyl projects including the Chernobyl Sasakawa Medical Cooperation Project which demonstrated a marked increase in the incidence of childhood thyroid cancer around Chernobyl, especially in the Gomel region, Belarus. Furthermore, we have performed both fieldwork and research to clarify the late effects of radiation exposure around Semipalatinsk Nuclear Testing Site and participated in bilateral official medical assistance projects between Japan and Kazakhstan to strengthen the medical infrastructure in this area. Through these humanitarian and scientific projects, we have been collaborating closely with our counterparts in the former USSR for the past 15 years. Here, we present a brief review of our past activities and future directions of international cooperative radiation research from Nagasaki to Chernobyl and Semipalatinsk.
