ABSTRACT
OBJECTIVES: We conducted an epidemiologic survey to evaluate the effect of the aircraft noise exposure on the health of the residents near the military airbases in Pyeongtaek City. METHODS: The evaluation of environmental noise level, questionnaire survey, and health examination were performed for 917 residents. The study population consisted of four groups: subjects who lived in the village close to the fighter airbase (high exposure), subjects who lived along the course of fighters (intermediate exposure), and subjects near a helicopter airbase, and the control group. RESULTS: The prevalence of the aircraft noise related accident and irritable bowel syndrome in the exposure groups were higher than that of the control group. The risks of noise induced hearing loss, hypertension and diabetes mellitus were higher in the exposed groups than in the control group. The prevalence of anxiety disorder and primary insomnia were higher in the exposed groups than in the control group. Prevalence odd ratios of the risk for primary insomnia after adjusting age, sex, agricultural noise, and occupation were 4.03 [95% confidence interval (95% CI) 1.56-10.47] for the subject near the helicopter airbase, 1.23 (95% CI 0.40-3.76) for those intermediately exposed to fighter noise, and 4.99 (95% CI 2.14-11.64) for those highly exposed to fighter noise. CONCLUSIONS: The results of the present study suggest that the aircraft noise may have adverse effects on hearing function, cardiovascular health and mental health. Therefore, it seems to be needed to take proper measures including the control of the aircraft noise and the management of the exposed people's health.

Gastric mucosal calcinosis (GMC) is a very rare condition that is characterized by the nodular deposition of calcium salts in the gastric mucosa. It has been associated with renal failure, gastric cancer, ingestion of aluminum- containing antacids and the use of sucralfate in organ transplant patients. The etiology of this condition is uncertain, but several theories have been proposed; the condition is due secondarily to hyperparathyroidism in renal failure and to the alkalinization of the gastric mucosa. We report here on two patients who had long-term use of bismuth and/or aluminum-containing antacids to treat their gastro-esophageal reflux symptoms. The esophagogastroduodenoscopy revealed acute gastritis patterns, and GMC was confirmed histologically with biopsy. When one patient stopped ingesting bismuth-containing antacid solution, the follow-up esophagogastroduodenoscopy and the biopsy revealed a completely improved state. We report here on these interesting cases and we include a brief review of the literature.

Adventitial cystic disease (ACD) is a rare, but well-characterized vascular disease. It is most commonly seen in the popliteal artery, but it has also been reported in the venous system. The most commonly involved segment has been the common femoral vein; the disease resulted in luminal compromise and extremity swelling. We report here on a case of adventitial cystic disease of the left external iliac vein that was initially misdiagnosed as deep vein thrombosis in a 68-year-old man who presented with a painless swelling of his left leg.
