The purpose of this study is to develop new standards for the disability evaluation with reference to existing laws and other study reports regarding disabilities for the rational evaluation of the diverse kinds of disfigurement in appearance and skin. Three plastic surgery specialists and 3 dermatology specialists developed a new standard for the disability evaluation which is appropriate for circumstances in Korea. Disability rate does not take into account the social occupation, gender or age of the patient, but instead, evaluate the Activity of Daily Living and the social adaptability of the appearance and skin disfigurement regardless of the balance between different disabilities. We tried to include most cutaneous disorders and categorized them into 3 types; congenital (Type 1), acquired (Type 2) as well as any permanent skin impairment sequelae of disease, trauma or treatment process (Type 3). For type 3 disorders, we tried to rate the score according to the size of involved skin lesion. The disability rate is determined by dividing the disability class into 8 steps based on the seriousness of each type of disability.

Injury to a peripheral nerve due to a drug injection is of particular concern, because of both its clinical and medicolegal implications. Among numerous agents, local anesthetic solutions are most frequently injected near the main nerve trunks. In spite of the low incidence of nerve fiber injury associated with these local anesthetic agents, there are several clinical reports of injury. The author experimentally induced injection injury into the rat sciatic nerve with 2% lidocaine HCL and 0.5% bupivacaine. The neurotoxicity of these agents to the peripheral nerve was observed by light and electron microscope. The results are as follows: 1) Some inflammatory round cells and vasodilation were observed in the surrounding loose areolar tissues immediately after injection. No fibroblast or fibrosis was observed on light and electron microscopic examinations. 2) Immediately after injection, the axons were seperated by the splitting of the collagen fibers between the axons. But within one week, the collagen fibers were reunited and compacted. 3) Most cytoplasmic organelles of the axon, including the microtubules and micro filaments, were quite normal and were not altered by injection injury. But the shape of the axon was changed and shrinked to create a large space from the myelin sheath. The above change returned to normal within one week. 4) The Schwann cells, maintained the normal structure of their cytoplasm and nucleus, but some Schwann cells were seperated from the axons, and floated in the collagen tissue. They were reunited with the axons within one week. 5) There were no significant histologic differences between lidocaine and bupivacaine. 6) The above changes were easily reversible and not severe enough to interfere with nerve function permanently. In conclusion, local injection of these agents is very safe to the peripheral nerve.

BACKGROUND: Suicide in young people is one of most common cause of death; and deliberate self-harm (DSH) is important indicator of suicide. It is currently unclear how old the rate begins to increase or when it reaches to the same level with adults. The purpose of this study was to find beginning age of DSH and compare their characteristics with adults. METHODS: This study retrospectively reviewed 5 years of nationwide prospective registry named Emergency Department-based Injury In-depth Surveillance (EDIIS) registry composed of all injured patients who were admitted to twenty tertiary university hospital emergency departments. Injured patients aged 29 years or younger from January 1, 2011 to December 31, 2015 were included. Incidence rate of DSH in all age was described. Patients were stratified by age: early teenage (11–15 years), late teenage (16–19 years), and early adulthood (20–29 years). Data of early teenage group were compared to those of other groups for examining their characteristics. RESULTS: Among 588,549 injury patients, 8,400 patients reported DSH. The rate began to rise at age 11 and reach at age 16 which was equivalent to that of age 20 to 29. Early teenage had significantly higher excess mortality ratio based injury severity score (EMR-ISS) and had almost same level without significant difference in operation incidence or mortality compared to late teenage and early adulthood. CONCLUSION: DSH rate began to rise at age 11, reaching adulthood level at age 16 in Korea.

BACKGROUND: To estimate the prevalence of the metabolic syndrome in Chuncheon city in those ages 45 and over and to evaluate the association between risk factors and the risk of the metabolic syndrome. METHODS: The subject of this study included 662 adults (males 276, females 386) aged 45 years or over who lived in Chuncheon city. The metabolic syndrome was defined as having 3 or more conditions inclnding abdominal obesity, high blood pressure, low HDL cholesterol, high triglyceride, and high fasting glucose. The association between the metabolic syndrome and its life-style related factors, such as smoking, exercise, and drinking, was examined, using multiple logistic regression. RESULTS: The prevalence of the metabolic syndrome from ATP III criteria was 30.1% in men, and 37.9% in women. The prevalence increased with age in women. In men, however, the prevalence increased to 55~64 age group and then it gradually decreased. The prevalence of the metabolic syndrome from Asia-Pacific criteria was 48.2% in men, and 46.6% in women. The prevalence increased with age in men and decreased in women. The highest prevalence among the individual components of diagnostic criteria of the metabolic syndrome in men was hypertension, followed by abdominal obesity, hypertriglyceridemia, low HDL-cholesterolemia, and high fasting blood glucose. And in women, it was abdominal obesity, followed by hypertension, low HDL cholesterolemia, hypertriglyceridemia, and high fasting blood glucose. After adjusting for potential covariates, current smoker was 1.93 times at a greater risk for the metabolic syndrome than non-smokers (95% confidence interval 1.06~3.51). CONCLUSION: The prevalence of the metabolic syndrome was higher than previously reported in Korea. Further studies are strongly needed to elucidate the factors which are related to the syndrome and to develop effective prevention guidelines, especially among the elderly.

OBJECTIVETo examinie the synergistic effects of Banxia Xiexin Decoction (, Known as Banhasasim-tang in Korean) extract (BXDE) on cisplatin-induced cytotoxicity in the A549 human lung cancer cell lines.

METHODSA549 cells were treated with varying concentrations (50-200 μg/mL) of cisplatin and BXDE alone or in combination for 96 h. We used 1-(4,5-dimethylthiazol-2-yl)-3,5-diphenylformazan assay and flow cytometry to analyze cell viability and apoptosis, respectively.

RESULTSThe exposure of cells to cisplatin and BXDE alone or in combination decreased cell viability dose- and time-dependently (P<0.05), which was found to be mediated by the apoptotic pathway as confirmed by the increase in the annexin V/propidium iodide- stained cell population and a ladder pattern of discontinuous DNA fragments. Furthermore, the apoptosis was inhibited by the pan-caspase inhibitor, benzyloxycarbonyl-Val-Ala-Asp (OMe) fluoromethylketone (z-VAD-FMK).

CONCLUSIONSBXDE significantly potentiated apoptotic effects of cisplatin in A549 cells. Moreover, apoptosis induced by BXDE might be the pivotal mechanism mediating its chemopreventative action against cancer.
