It is necessary to install ventilation facilities in the laboratory and to regularly monitor harmful gases including formalin for safe environment of the dissection laboratory. However, there are no indicators that can identify the current status of ventilation facilities, safety equipment, and protective equipment in the dissection laboratory. In this study, the status of safety management of anatomical lab at domestic medical, dental, and oriental medical universities are investigated through an online questionnaire. Of the total 32 universities, 7 universities (21.8%) regularly monitor harmful gases such as formalin in the dissection lab, 13 universities (40.6%) do it on an irregular basis, and 12 do not do it at all. Seven universities (21.8%) are using the exhaust-type dissection table, 24 universities (75%) are not using it. Regarding the need for standards for manpower and facilities in the management of the anatomy lab, 7 universities (21.8%) are mediocre, 21 universities are necessary (65.6%), and 4 universities (12.5%) are very necessary. The responsibility for anatomy lab is 27 universities (84.3%) of the schools that responded as head professors of the department of anatomy, 3 universities (9.3%) of technicians, and 2 universities (6.2%) of the dean of the medical school. Regarding the need for standards for the anatomical lab, 7 universities (21.8%) are very necessary, 21 universities (65.6%) are necessary, and 4 universities (12.5%) are mediocre. Based on this data, the standard for the quality improvement and safety of anatomical education should be prepared.

Background/Aims:
Although statins are widely used to reduce the risk of cardiovascular disease (CVD) including stroke and myocardial infarction (MI), it is reported that statin use increases the incidence of herpes zoster (HZ) that is associated with increased risk of CVD. So, we evaluated the mediation effect of HZ caused by statin use on CVD.
Methods:
We analyzed a prospective cohort from the National Health Insurance Service-database of South Korea. All individuals received a medical check-up and were followed-up from 2002 to 2013.
Results:
A total of 275,382 individuals > 40 years old were followed up for 11 years from 2003. Of these, 11,415 people (4%) were classified as statin users and 263,967 (96%) as non-statin users. Those who used statins had significantly lower risks of cardiovascular events, stroke, and MI compared with non-statin users; the adjusted hazard ratios in the multivariate analysis were 0.90 (95% confidence interval [CI], 0.82 to 0.98), 0.88 (95% CI, 0.80 to 0.98), and 0.91 (95% CI, 0.79 to 1.07), respectively. When we calculated the mediating effect of cardiovascular events by statin use through HZ, 11.6% of the total beneficial effect of cardiovascular events by statin use was mitigated through the occurrence of HZ caused by statin use. This mediating effect was higher in the younger age group (< 60 years).
Conclusions
This study showed that statin use reduced CVD by 10%, but the protective effect of statin use against CVD was mitigated by approximately 10% through the development of HZ caused by statin use.

Diabetic calcaneal insufficiency avulsion (CIA) fracture are unusual injury. The treatment may be challenging due to the low healing potential from diabetes or Charcot neuroarthropathy, so far. The poor surgical outcomes and surgical failures from treatment of the traumatic calcaneal avulsion fractures were associated with poor bone stock, lack of proper fixation, and the wound problem. Thus, the proper treatment for diabetic CIA fracture was still controversy. This report described two cases of diabetic CIA fracture treated with fixation of fracture fragment and calcaneal tenodesis. In both cases, fracture fragments were re-avulsed despite of fixation. Through investigation for the fate of fracture fragment from these cases, we discussed the proper treatment strategy in diabetic CIA fracture.

The Korea Chronic Obstructive Pulmonary Disorders Subgroup Study Team (Korea COPD Subgroup Study team, KOCOSS) is a multicenter observational study that includes 956 patients (mean age 69.9 ± 7.8 years) who were enrolled from 45 tertiary and university-affiliated hospitals from December 2011 to October 2014. The initial evaluation for all patients included pulmonary function tests (PFT), 6-minute walk distance (6MWD), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and the COPD-specific version of St. George's Respiratory Questionnaire (SGRQ-C). Here, we report the comparison of baseline characteristics between patients with early- (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage I and II/groups A and B) and late-stage COPD (GOLD stage III and IV/groups C and D). Among all patients, the mean post-bronchodilator FEV1 was 55.8% ± 16.7% of the predicted value, and most of the patients were in GOLD stage II (520, 56.9%) and group B (399, 42.0%). The number of exacerbations during one year prior to the first visit was significantly lower in patients with early COPD (0.4 vs. 0.9/0.1 vs. 1.2), as were the CAT score (13.9 vs. 18.3/13.5 vs. 18.1), mMRC (1.4 vs. 2.0/1.3 vs.1.9), and SGRQ-C total score (30.4 vs. 42.9/29.1 vs. 42.6) compared to late-stage COPD (all P < 0.001). Common comorbidities among all patients were hypertension (323, 37.7%), diabetes mellitus (139, 14.8%), and depression (207, 23.6%). The data from patients with early COPD will provide important information towards early detection, proper initial management, and design of future studies.

This prospective cohort study was performed to estimate the morbidity and mortality with 790 patients over 50-yr of age that sustained a femoral neck or intertrochanteric fracture from 2002 to 2006, followed-up for a mean of 6 yr (range, 4 to 9 yr). Crude and annual standardized mortality ratios (SMRs) were calculated; and mortalities in the cohort and the age and sex matched general population were compared. The risk factors on mortality and activities pre- and post-injury were assessed. Accumulated mortality was 16.7% (132 patients) at 1 yr, 45.8% (337 patients) at 5 yr, and 60% (372 patients) at 8 yr. SMR at 5 yr post-injury was 1.3 times that of the general population. Multivariate analysis demonstrated that age (OR, 1.074; 95% CI, 1.050-1.097; P<0.001), woman (OR, 1.893; 95% CI, 1.207-2.968; P=0.005), and medical comorbidity (OR, 1.334; 95% CI, 1.167-1.524 P<0.001) were independently associated with mortality after hip fracture. Only 59 of the 150 patients (39.3%) who were able to ambulate normally outdoors at preinjury retained this ability at final follow-up. Patients with a hip fracture exhibits higher mortality at up to 5 yr than general population. Age and a preinjury comorbidity are associated with mortality.

The aim of this project was to use 3D scanning data collected at incident scenes and various evidence to 1) develop surveying methods based on 3D data consisting of overall and detailed scene evidence, captured by long-range and micros-canner, which can be shared by personnel working in different fields such as forensic medicine, video analysis, physical analysis, traffic engineering, and fire investigation; 2) create digital storage for human skeletons and set the foundation for virtual anthropology; and 3) improve the credibility of 3D evidence by virtual remodeling and simulation of incident scenes and evidence to provide a basis for advanced and high-tech scientific investigation. Two complete skeletons of male and female were scanned using 3D micro-scanner. Each bone was successfully reproduced and assembled in virtual space. In addition, recreating evidence scheduled for invasive examination by creating RP (rapid prototype) was possible. These outcomes could play an important role in setting up the new field of virtual anthropology. Case-specific surveying methods were developed through analysis of 3D scanning data collected by long-range surface scanners at the scenes of vehicular accidents, falls, shootings, and violent crimes. A technique and recording method was also developed for detecting forged seals by micro-scanning the pressure exerted on the seal. Appraisal methods developed in this project could be utilized to secure 3D data of human skeletal remains and incident scenes, create a standard for application, and increase objectivity, reproducibility, and accuracy of scanning methods. We plan to develop case-specific 3D data analysis techniques to improve the credibility of analysis at the NFS and to establish a 3D data collection and analysis team.

BACKGROUND: Pneumonia is commonly seen in outpatient clinics. it is widely known as the most common cause of death from infectious disease. Pneumonia has been diagnosed by its typical symptoms, chest X-ray and blood tests. However, both chest X-rays and blood tests have limitations in diagnosis. Thus primary care clinicians usually have been constrained due to a lack of adequate diagnostic tools. Vibration response imaging (VRI) is a newly emerging diagnostic modality, and its procedure is non-invasive, radiation-free, and easy to handle. This study was designed to evaluate the diagnostic usefulness of the VRI test among pneumonia patients and to consider its correlation with other conventional tests such as Chest X-ray, laboratory tests and clinical symptoms. METHODS: VRI was performed in 46 patients diagnosed with pneumonia in Konkuk University Medical Center. VRI was assessed in a private and quiet room twice: before and after the treatment. Sensors for VRI were placed on a patient's back at regular intervals; they detected pulmonary vibration energy produced when respiration occurred and presented as specific images. Any modifications either in chest X-ray, C-reactive protein (CRP), white blood cell count (WBC) or body temperature were compared with changes in VRI image during a given time course. RESULTS: VRI, chest X-ray and CRP scores were significantly improved after treatment. Correlation between VRI and other tests was not clearly indicated among all patients. But relatively severe pneumonia patients showed correlations between VRI and chest X-ray, as well as between VRI and CRP. CONCLUSION: This study demonstrates that VRI can be safely applied to patients with pneumonia.

PURPOSE: The purpose of this study was to evaluate the clinical results and prognostic factors of the extension block technique for treating a bony mallet finger. MATERIALS AND METHODS: Between July 2002 and January 2009, forty-nine patients who underwent the extension block technique for a bony mallet finger were evaluated. The minimum period of follow up was 6 months. The type of fracture was classified by the Wehbe and Schneider method. The results were evaluated by the Crawford classification. The prognostic factors were analyzed according to age, gender, the timing of the surgery, the mallet fragment angle and the residual displacement. RESULTS: According the Crawford classification, there were 22 excellent, 20 good, 6 fair and 1 poor results. The poor prognostic factors were an older patient age, subluxation, a smaller mallet fragment angle and smaller postoperative displacement (p<0.05). CONCLUSION: The prognostic factors of the extension block technique for bony mallet finger were the patient age, subluxation, the mallet fragment angle (more than 30 degrees) and the postoperative displacement.

PURPOSE: We wanted to assess the radiological and clinical results and the prognostic factors after an operation for capitellar fractures associated with/without other injury around the elbow. MATERIALS AND METHODS: Among the 25 patients (mean age: 49 years-old) who underwent open reduction and internal fixation for capitellar fractures, there were nineteen type 1 fractures and six type 3 fractures. The mean follow up period was 14.8 months. We assessed the factors affecting the radiological and functional results, such as the fracture pattern, the patient age and the surgical approaches. RESULTS: In 24 of 25 patients, bony union was achieved at postoperative 1 year. There were eighteen excellent, four good, two fair and one poor functional results according to the Broberg and Morrey elbow score. The most common type was type 1 and the most common associated injury was lateral condylar fracture. The patients with type 1 fracture rather than the patients with type 3 fracture and the patients who had an extraarticular associated fracture rather than an intraarticular associated fracture had better clinical outcomes. CONCLUSION: 22 (88%) of the patients were satisfied at the result. The type of capitellar fracture and an associated intraarticular elbow fracture were shown to be important prognostic factors in this study.

The Journal of the Korean Orthopaedic Association 2009;44(6):593-598
PURPOSE: This study evaluated the prognostic factors of modified Thompson quadricepsplasty for a stiff knee. MATERIALS AND METHODS: From February 1987 to February 2007, 38 knees of 38 patients were managed with modified Thompson quadricepsplasty for a stiff knee. Thirty three males and 5 females were enrolled with a mean age of 36 years. The average follow-up duration was 92 months (range, 18 to 133 months). The most common cause of the stiff knee was a fracture around the knee in 33 cases. Multivariate logistic regression analysis was performed to evaluate the prognostic factors. RESULTS: Multivariate analysis showed that the gain of ROM after surgery was negatively correlated with the ROM before surgery (p<0.0001), and flexion contracture at the last follow up was positively correlated with the initial flexion contracture (p<0.0001). CONCLUSION: In a stiff knee, modified Thompson quadricepsplasty should be considered as soon as possible if the patient cannot gain an acceptable ROM through conservative management. More improvement in the ROM can be obtained in those with a more severe limitation of motion.
