The purpose of this study is to determine how accuratively and reliably the Perdriollo s method can measure vertebral rotaton according to the level of vertebra and true axial rotation. Standard AP radiographs were taken using 10 dry human vertebra (two set of T3, T6, T9, T12, L3) with 5degrees increments in axial rotation, ranging from 0degrees to 50degrees. In order to evaluate the reliability of Perdriolle s method, three observers measured each radiograph twice, and intet-and intraobserver variance were estimated. The accuracy of Perdriolle's method was analyzed by total error analysis, root mean square error (RMSE) and Deviation of differences. 372 errors were made in the 660 measurement and 88.9% of all measurements were within +/- 5degrees of true rotation angle. There were no signigicant difference in the intraobserver measurement at each level whereas interobserver measurements were significantly different only at T3 level. The measurement was also the least accurate at T3 (RMSE=6.2292). We concluded that Perdriolle's method using torsion meter is an accurate and reliable one to measure the vertebral rotation with less accuracy and reliability in high thoracic level.

PURPOSE: The objective of this study was to investigate whether financial coverage by the national insurance system for patients with lower economic conditions can improve their 1-year mortality after intensive care unit (ICU) discharge. MATERIALS AND METHODS: This study, conducted in a single tertiary hospital, used a retrospective cohort design to investigate discharged ICU survivors between January 2012 and December 2016. ICU survivors were classified into two groups according to the National Health Insurance (NHI) system in Korea: medical aid program (MAP) group, including people who have difficulty paying their insurance premium or receive medical aid from the government due to a poor economic status; and NHI group consisting of people who receive government subsidy for approximately 2/3 of their medical expenses. RESULTS: After propensity score (PS) matching, a total of 2495 ICU survivors (1859 in NHI group and 636 in MAP group) were included in the analysis. Stratified Cox regression analysis of PS-matched cohorts showed that 1-year mortality was 1.31-fold higher in MAP group than in NHI group (hazard ratio: 1.31, 95% confidence interval, 1.06 to 1.61; p=0.012). According to Kaplan-Meir estimation, MAP group also showed significantly poorer survival probability than NHI group after PS matching (p=0.011). CONCLUSION: This study showed that 1-year mortality was higher in ICU survivors with low economic status, even if financial coverage was provided by the government. Our result suggests the necessity of a more nuanced and multifaceted approach to policy for ICU survivors with low economic status.

Primary biliary cirrhosis(PBC) is a chronic cholestatic liver disease of unknown origin. The small and medium sized intrahepatic bile ducts are destroyed by an inflammatory process, which, it has been suggested, is of the autoimmune type. It is strongly associated with the presence of antimitochondrial antibodies, predominantly IgM and IgG. The liver changes are classified into four stages, of which stage IV represents the development of cirrhosis, which required orthotropic liver transplantation in the longrun. The prevalence rates was reported 128 per millon in Sweden , but the disease is relatively rare in Oriental area. In medical treatment, long-term administration of ursodeoxycholic acid improves both clinical and biochemical signs, slows the progression of the disease and reduces the complication requiring liver transplantation. We report two cases of PBC, one with histologically proven cirrhosis, and the other with bile duct destruction consistent with stage III and hypothyroidism.

Recently, there have been many changes in the area of healthcare. There is no certainty how these changes will affect the healthcare system and public health. However, to at least have these changes positively implemented, it is clear that evaluation through continuous monitoring is necessary. The enforcement of the Medical Institution Accreditation and Medical Dispute Mediation Law as well as legal revisions regarding the public healthcare system are changes to improve the quality of healthcare, while at the same time, provide penalties for infractions of the new law such as medicine/medical device rebates; moreover, legal revisions regarding telemedicine are anticipated to impartially vitalize technical development as well as the pharmaceutical industry. For these changes to have a positive effect on the medical field and people's lives, an accurate comprehension of the system and understanding of the details is necessary to be able to respond sensitively to any changes in the future. Therefore, this paper examined the background information on the current discussion on the changes in the healthcare system, examined the detailed content of the system, and reviewed the areas that were in dispute as well as the main issues to contemplate the expected effects of the changes and future tasks that may be generated as a result. These considerations will act as foundation for an in depth understanding of recent trends in the healthcare system.

Odontogenic keratocyst (OKC) accounts for 3-11% of all odontogenic cysts. OKC is a benign intra-osseous odontogenic tumor, but what makes this cyst special is its aggressive behavior and high recurrence rate. OKC is relatively aggressive compared to other odontogenic cysts, but its malignant transformation is considered extremely rare. Squamous cell carcinoma associated with odontogenic keratocysts have rarely been reported in the medical literature. We recently experienced a case of a 63-year-old man finally confirmed with squamous cell carcinoma of the mandible, which was initially diagnosed as a benign odontogenic keratocyst. Surgical resection was performed as definitive treatment. Therefore, we present this unique case with a review of the literature.

The link between toxic hepatitis and exposure to organic solvents is relatively well-documented, but there are no specific laboratory or histologic findings diagnostic of chemical-induced hepatitis. Clinical history, therefore, is very important in making a diagnosis. A history of glue sniffing is sometimes overlooked and glue sniffing has not received much attention as a cause of hepatitis. Toluene, a main organic solvent in glue, is known to cause disturbances in various organs such as the heart, nervous system, liver and kidneys. We present a case of hepatitis in an individual who has sniffed glue for euphoria for 3 years. There is an increasing tendency towards glue sniffing among young adolescents today, so toxicity caused by exposure to organic solvents should be considered as one possible cause of hepatitis in young adolescents.

The prognosis of advanced hepatocellular carcinoma (HCC) tends to be poor. Spontaneous regression of this lesion is extremely rare. In this report, we describe a case of HCC which spontaneously regressed along with a metastatic lesion of the chest wall. A huge HCC in the right lobe, the largest diameter of which was about 15x12 cm, developed in a 72-year-old man. He and his family refused further treatment. Three months after the diagnosis, metastasis to the chest wall was detected. We prescribed a painkiller for him in order to alleviate chest pain. Fourteen months after the diagnosis, the tumor size of the primary lesion was downsized to 3x4 cm in diameter. A biopsy taken from the chest wall proved to be clear cell HCC (CHCC). Since then, the metastatic lesion has also disappeared. Here, we report this unusual histologically proven CHCC with literature reviews.

OBJECTIVE: To evaluate the early clinical experience associated with radiofrequency (RF) ablation in patients with renal cell carcinoma (RCC). MATERIALS AND METHODS: The RF ablation treatment was performed on 17 tumors from 16 patients (mean age, 60.5 years; range, 43-73 years) with RCC. The treatment indications were localized, solid renal mass, comorbidities, high operation risk, and refusal to perform surgery. All tumors were treated by a percutaneous CT (n = 10), followed by an US-guided (n = 2), laparoscopy-assisted US (n = 2), and an open (n = 2) RF ablation. Furthermore, patients underwent a follow-up CT at one day, one week, one month, three and six months, and then every six months from the onset of treatment. We evaluated the technical success, technical effectiveness, ablation zone, benign periablation enhancement, irregular peripheral enhancement, and complications. RESULTS: All 17 exophytic tumors (mean size, 2.2 cm; range, 1.1-5.0 cm) were completely ablated. Technical success and effectiveness was achieved in all cases and the mean follow-up period was 23.8 months (range, 17-33 months). A local recurrence was not detected in any of the cases; however, five patients developed complications as a result of treatment, including hematuria (n = 2), mild thermal injury of the psoas muscle (n = 1), mild hydronephrosis (n = 1), and fistula formation (n = 1). CONCLUSION: The RF ablation is an alternative treatment for exophytic RCCs and represents a promising treatment for some patients with small RCCs.
