Prevalence of snoring and high risk of obstructive sleep apnea syndrome in young male soldiers in Korea.
There are little information on prevalence of obstructive sleep apnea syndrome (OSAS) and clinical features in the young military population. The purpose of this study was to estimate the prevalence of snoring and high risk of OSAS in young male soldiers in Korea and to identify the risk factors of OSAS. A total of 665 participants (aged 20-23 yr) who visited the Armed Forces Ildong Hospital for regular physical examination were enrolled. ⋯ The prevalence of high arched palate, tongue indentation, long uvula, large tonsil and retrognathia was significantly higher in the high risk OSAS group. High arched palate, long uvula or low lying soft palate, tonsil size III or IV, Epworth Sleepiness Scale score > 10 and obesity (BMI > 27 kg/m(2)) were found to independently predict OSAS. For early identification and treatment of young soldiers with OSAS in a military environment, a precise screening by questionnaire and physical examination is needed.

Incidence of deep vein thrombosis after spinal cord injury in Korean patients at acute rehabilitation unit.
Deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) remain significant causes of morbidity, mortality in patients with spinal cord injury (SCI). Since incidence of DVT after SCI in Korean population has not been much studied, we retrospectively analyzed the medical records of 185 SCI patients admitted for acute rehabilitation unit to investigate the incidence of DVT. Color Doppler ultrasonography was performed to screen for the occurrence of DVT at the time of initial presentation to acute rehabilitation unit. ⋯ Symptomatic pulmonary embolism was evident in 7 patients without an episode of sudden death. Therefore, it is concluded that the incidence of DVT after SCI in Korean patients is comparable with that in Western populations. This result suggests that pharmacologic thromboprophylaxis should be considered in Korean patients with SCI.

Factors predictive of high-risk adenomas at the third colonoscopy after initial adenoma removal.
Evaluating predictive factors for high-risk adenomas at the third colonoscopy based on two prior colonoscopies may help evaluate high-risk adenoma at the third colonoscopy. We analyzed clinical data of 131 patients at Severance Hospital from January 1997 to January 2011. All of them underwent two subsequent colonoscopies after removal of adenomas during an initial colonoscopy. ⋯ Among the 67 patients who had high-risk adenoma only once at the first or second colonoscopy, 15 (22.4%) patients had high-risk adenoma at the third colonoscopy but among the 44 patients without high-risk adenoma at the first and second colonoscopies, only 1 (2.3%) patient had high-risk adenoma at the third colonoscopy (P < 0.001). A multivariate time dependent covariate Cox regression analysis confirmed that high-risk adenoma at the first and/or second colonoscopy (HR, 9.56; 95% CI, 2.37-38.54; P = 0.002) was independent predictor of high-risk adenoma at the third colonoscopy. Given these findings, data from two prior colonoscopies, not one prior examination, may help identify high-risk populations at the third colonoscopy who require careful colonoscopic surveillance.
