A retrospective study was made of 10 consecutive patients who underwent mandibular reconstruction with PCBM from December 1994 to July 1996. Free autogenous iliac bone in the from of particulate cancellous bone and marrow was densely packed into the crib that was adapted to bridge the mandibular discontinuity defect. Frozen-treated autogenous mandibular bone, splitted autogenous rib, and titanium mesh(Dumbach, Leibinger) were used as cribs carrying the PCBM. All ten cases underwent successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequential panoramic radiographs. The mean horizontal dimension of the madibular defects was 44mm and the mean vertical dimension of the reconstructed segments was 23mm. The bony height of the reconstructed segments retained about 90% of the bony height of over a 1-year period. We confirmed that PCBM grafts were the most successful and predictable grafts in mandibular discontinuity reconstruction.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

Background and Objectives:
Hypertension awareness, treatment, and control have been substantially improved in the last decades worldwide, but hypertension management in younger adults is still challenged. We analyzed a nationally representative sample of Korea to investigate factors affecting hypertension management among the young Korean population.
Methods:
Among 8,024 young adults aged 30–49 years from the 2014–2018 Korea National Health and Nutrition Examination Survey, 1,103 participants with hypertension were analyzed to identify factors associated with hypertension management status. Multiple logistic regression models were conducted separately by sex.
Results:
Young adults with hypertension showed a low rate of awareness (35.8%), treatment (30.9%), and control (23.0%). The older age (40–49 years), obese (body mass index ≥25.0 kg/ m 2 ), having diabetes mellitus (DM), and having past-history of cardiovascular disease were positively associated with awareness, and taking health examination in the past 2 years were positively associated with both treatment and control of hypertension among male. Young females who were older (40–49 years), rural residents, unemployed, not taking sodium over the recommended amount, having dyslipidemia, and having DM showed a higher likelihood of awareness. Young females who have not experienced unmet medical needs in the past year were more likely to be treated or controlled with hypertension.
Conclusions
The factors associated with hypertension awareness, treatment, and control were different by sex and age group. Enhancing attention on hypertension among young hypertension and encouraging them to visit clinics would be key strategies to improve hypertension management among the young hypertensive population.
