Background: The purpose of this study was to evaluate and compare deltoid origin status following large rotator cuff repair carried out using either an open or an arthroscopic method with a propensity score matching technique. Methods: A retrospective review of 112 patients treated for full-thickness, large rotator cuff tear via either a classic open repair (open group) or an arthroscopic repair (arthroscopic group) was conducted. All patients included in the study had undergone postoperative magnetic resonance imaging (MRI) and clinical follow-up for at least 12 and 18 months after surgery, respectively. Propensity score matching was used to select controls matched for age, sex, body mass index, and affected site. There were 56 patients in each group, with a mean age of 63.3 years (range, 50-77 years). The postoperative functional and radiologic outcomes for both groups were compared. Radiologic evaluation for postoperative rotator cuff integrity and deltoid origin status was performed with 3-Tesla MRI. Results: The deltoid origin thickness was significantly greater in the arthroscopic group when measured at the anterior acromion (P=0.006), anterior third (P=0.005), and middle third of the lateral border of the acromion level (P=0.005). The deltoid origin thickness at the posterior third of the lateral acromion was not significantly different between the arthroscopic and open groups. The arthroscopic group had significantly higher intact deltoid integrity with less scarring (P=0.04). There were no full-thickness deltoid tears in either the open or arthroscopic group. Conclusions: Open rotator cuff repair resulted in a thinner deltoid origin, especially from the anterior acromion to the middle third of the lateral border of the acromion, at the 1-year postoperative MRI evaluation. Meticulous reattachment of the deltoid origin is as essential as rotator cuff repair when an open approach is selected.

Purpose: To understand the epidemiology of head trauma and the utilization of brain CT in Korea, we analyzed a national sampling data set, the National Patient Sample obtained from the Health Insurance Review and Assessment Service. Methods: We retrospectively collected and analyzed demographic and clinical data on enrolled patients from the National Patient Sample based on medical claims data for 2009. The data included patient's age, sex, treatment date, diagnosis codes, procedure codes related with CT, holiday or night consultation fee, and fee for emergency management services. Results: In 2009, the estimated population with head trauma was 819,059(1.8%), and the rate of brain CT utilization was 22.4%. Children ages 5 to 15 were the most commonly injured group(22.8%), but had the lowest brain CT utilization(16.5%). The mean age of the estimated population with head trauma was $34.9{\pm}0.5years$ old, and male patients accounted for 60.5% of that population. Intracranial injury was found in 8.6% of all head traumas, and the rate of intracranial injury in children was lower than it was in adults(4.1% vs. 10.9%, p<0.001). Twenty- three percent of patients with head trauma visited the emergency department (ED). More patients with head trauma visited medical facilities in the daytime on weekdays(66.5% vs. 33.5%, p<0.001), but head CT was performed more frequently at night or on weekends/holidays(16.1% vs. 34.7%, p<0.001) There is low incidence of head trauma in the winter in children (p<0.001). In the multivariate logistic regression analysis, patients who were adults, female, or ED visitors were more likely to undergo brain CT (odds ratio (OR): 1.65, 95% confidence interval (CI): 1.47-1.84; OR: 1.40, 95% CI: 1.27-1.54; OR: 7.80, 95% CI: 6.91-8.80, respectively). Conclusion: In this study, we analyzed the national epidemiologic trend for head trauma, and the pattern of utilization of brain CT.

본 연구는 HIV병 사망자 중 HIV병과 결핵이 동반사망한 분율을 조사하고 그 관련 요인을 분석하였다. 2002년부터 2010년까지 사이에 HIV병 사망자는 모두 774명으로 결핵이 동반사망한 분율은 10.1%로 나타났다. 그런데 이러한 분율은 2005년부터 2007년 사이에 16.3%까지 치솟았지만 2008년부터 2010년 사이에는 4%까지 감소하는 경향을 보였다. 또한 HIV-결핵 동반사망 분율은 젊은 계층에서 더 높았고 배우자가 있는 그룹과 교육을 잘 받은 그룹에서는 유의하게 낮은 경향을 보였다. 이처럼 활동성이 높은 젊은층에서 HIV-결핵 동반사망 분율이 높고 사회경제적 안정계층에서 HIV-결핵 동반사망 분율이 낮은 것은 비슷한 해외 연구에서도 유사하게 나타나고 있어 HIV-결핵 동반사망의 예방 가능성을 시사한다. 한국은 다행히 점차 HIV-결핵 동반사망 분율이 낮아지고 있어 HIV감염자에 대한 결핵 예방사업의 효과가 나타나고 있음을 시사하고 이후 이러한 지표의 지속적인 모니터링이 필요함을 보여주고 있다.

Background: In Korea, the prevalence of obesity has steadily increased, and the socioeconomic burden of obesity has increased along with it. In 2015, the National Health Insurance Service (NHIS) signed a memorandum of understanding with the Korean Society for the Study of Obesity (KSSO), providing limited open access to its databases so that the status of obesity and obesity management could be investigated. Methods: Using NHIS databases, we analyzed nationwide population-based studies for obesity using the definition of obesity (body mass index ${\geq}25kg/m^2$) in subjects over the age of 20. Age and sex standardization were used for all data. Results: The KSSO released the 'Obesity Fact Sheet 2016' using the 2006-2015 NHIS Health Checkup database. The prevalence of obesity steadily increased from 28.7% in 2006 to 32.4% in 2015, and the prevalence of abdominal obesity also steadily increased from 18.4% in 2009 to 20.8% in 2015. The prevalence of class II obesity steadily increased from 2006 to 2015, such that the total prevalence was 4.8% in 2015 (5.6% in men and 4.0% in women). The highest prevalence of obesity was found in Jeju Island, while the lowest prevalence was found in Daegu City. The highest prevalence of abdominal obesity was also found in Jeju Island, while the lowest prevalence was found in Gwangju City. Conclusion: Based on the Obesity Fact Sheet 2016, a strategy for reducing the prevalence of obesity is needed, especially in Korean men.

Objectives : The purpose of this study is to investigate the clinical effectiveness of Korean medical combination treatment for cervical disc herniation. Methods : This is an observational study. 102 patients diagnosed with cervical disc herniation by MRI (Magnetic Resonance Imaging) were investigated from January, 2015 through to December, 2015 at Daejeon Jaseng Hospital of Korean Medicine. They were sorted according to the distribution of sex, age, causing factor, the period of disease, admission day and pain area. All patients were treated with acupuncture, Chuna treatment, and herbal therapy and physical therapy during the admission period. After treatment, NRS (Numeric Rating Scale), NDI (Neck Disability Index) and EQ-5D were assessed to evaluate the treatment efficacy. Results : There were more females than Males with a ratio of 1 : 1.37, the age of fifty was the most with 35.29 %, reason unknown was the most with 72.55 % and the subacute stage was the most with 38.24 %. According to disc herniation types, patients with protruded disc types were the most with 66.67 % and a lesion of C5/6 was the most with 41.18 %. For patients diagnosed with cervical disc herniation, neck and shoulder pain NRS decreased from $6.43{\pm}1.77$ to $3.96{\pm}1.96$(p<0.001) and radiating pain NRS decreased from $5.64{\pm}1.96$ to $3.57{\pm}1.88$ (p<0.001). NDI decreased from $41.72{\pm}14.04$ to $30.84{\pm}15.34$(p<0.001), and the EQ-5D index increased from $0.68{\pm}0.17$ to $0.79{\pm}0.14$(p<0.001) after treating cervical disc patients. Conclusion : Korean medical combination treatment might be effective in decreasing pain and raising the life quality of patients with cervical disc herniation.

Objectives This study aims to find out effect of Korean medicine treatment on managing thoracolumbar compression fractures through retrospective observational study. Methods Among hospitalized patients at the Department of Korean Medicine Rehabilitation from January 1st, 2018 to February 28th, 2023, a total of 24 inpatients who were diagnosed with thoracolumbar compression fractures and received Korean medicine treatment were included in this study. Numeric rating scale (NRS) was used for pain assessment and clinical variables such as sex, symptoms, age, thoracolumbar injury classification and severity (TLICS) scores were collected. For subgroup analysis to analyze factors affecting treatment response, we divided patients into responders and non-responders according to NRS change. For statistical analysis, we compared before/after hospitalization and analyzed distinct features between two groups. Results Most of the patients were in their 70s and 83.33% were female. Average hospitalization period was 24.54±11.91 days. All patients had back pain as their chief complaint and only 2 patients received surgeries. In TLICS, only 1 patient got score 6, which represented surgery indication. After Korean medicine treatment, NRS of almost every patient got lower significantly at the time of discharge (3.02±1.93) than admission (5.52±1.95). Comparing two groups, responders had lower NRS at the time of discharge and TLICS score of them were lower than non-responders. Conclusions Our results show that Korean medicine treatment for thoracolumbar compression fractures was effective in reducing pain. There were distinct clinical features such as age, past history, surgeries between those with significant improvement in pain scores and those who did not.

흰쥐 뇌의 선조체로부터 catecholamine, indoleamine 및 대사산물을 동시분석할 수 있는 간편한 방법을 제시하였다. 기기는 ECD를 장착한 HPLC를 사용하였고, 고정상인 $C_{18}$ 컬럼에서, 이 동상은 10mM citric acid, 0.13mM $Na_4EDTA$, 0.58mM SOS를 함유하는 35mM sodium acetate buffer(pH 3.4) : MeOH=85:15가 최적이었다. 이 때 컬럼온도는 $30^{\circ}C$였다. 이 조건으로 dopamine(DA), 3, 4-dihydroxyphenyl acetic acid(DOPAC), homovanilic acid(HVA), 5-hydroxyindole acetic acid(5-HIAA), serotonin(5-HT) 및 noradrenaline(NA)을 미량까지 분석할 수 있었고, 검출한계는 각 성분에 대해 1회 주입당 2~10pg이었다. 이 방법으로 흰쥐의 주령 및 성별에 따른 선조 체내 생체아민과 대사산물의 함량을 비교하였다. 7주령 쥐에서 암컷은 수컷보다 DA와 5-HT의 함량이 유의성 있게 높은 것으로 나타났으며, 주령이 증가함에 따라 암컷에서 DOPAC의 함량이 유의적으로 증가하였다.
