Background: There is increasing interest in the quality of health care and considerable efforts are being made to improve it. Rheumatoid arthritis (RA) is a disease that can result in favorable outcomes when appropriate diagnosis and treatment are provided. However, several studies have shown that RA is often managed inappropriately. Therefore, the Korean College of Rheumatology aimed to develop quality indicators (QIs) to evaluate and improve the health care of patients with RA. Methods: Preliminary QIs were derived based on the existing guidelines and QIs for RA. The final QIs were determined through two separate consensus meetings of experts. The consensus was achieved through a panel of experts who voted using the modified Delphi method. Results: Fourteen final QIs were selected among 70 preliminary QIs. These included early referral to and regular follow-up with a rheumatologist, radiographs of the hands and feet, early initiation and maintenance of disease-modifying anti-rheumatic drug (DMARD) therapy, periodic assessment of disease activity, screening for drug safety and comorbidities,including viral hepatitis and tuberculosis before biologic DMARD therapy, periodic laboratory testing, supplementation with folic acid, assessment of the risk for cervical spine instability before general anesthesia, patient education, and specialized nurse. Conclusion These QIs can be used to assess and improve the quality of health care for patients with RA.

Tomb with lime-soil mixture barrier (LSMB) was constructed by the people from upper class people of Joseon Dynasty. The coffin of LSMB was surrounded by hard concrete barriers, being successfully protected from outside invasions until the archaeological excavation begins. The human remains were extremely preserved well, providing important information on the health and illness of the people of Joseon dynasty. Recent investigation into human skeletons from LSMB in Yong-in city was another forensic anthropological case that was very meaningful to our research. During the examination on the elderly Joseon female bones, we discovered unusual saw-marks on the shaft of both tibiae. We could not find any osteological evidences suggestive of healed bone process. Considering archaeological and anthropological findings altogether, the occurrence time of saw-marks was considered to be perimortem period. However, as for why such a saw mark was made on the tibiae, we did not get any information about it. We expect that this report facilitate other researcher to do explore the usefulness of forensic anthropology examination on the similar human skeleton cases identified in various archaeological ruins.

Subintimal angioplasty is an effective method for the treatment of long superficial femoral artery (SFA) occlusions. One of the major limiting factors for the success of this procedure is the failure to re-enter the true lumen. The recently introduced luminal re-entry devices provide a high technical success rate, but failures can occur. In such cases, a retrograde popliteal approach can serve as a potential backup option. However, the need to reposition the patient remains a drawback. Here, we report a case of an 81-year-old male with a long SFA occlusion treated using a retrograde distal SFA approach in the supine position after the initial failure of antegrade angioplasty.

BACKGROUND: Spectacle contact allergy is not infrequent. The fine scratches on the spectacle frames which may play a role in the sensitization to the potential allergenic components have not been studied. OBJECTIVE: We sought the relationship between the scratches on the spectacle frames and the allergic contact dermatitis (ACD) in the Republic of Korea. METHODS: A total of 42 Korean patients with ACD at the spectacle contact sites were enrolled. Their spectacle frames were examined with the dimethylglyoxime (DMG) test and analyzed by the scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Patch tests (thin-layer rapid use epicutaneous test [TRUE tests]) were performed to identify the skin allergens. RESULTS: The DMG-positive spectacle frames were identified in 78.5% of the frames. The SEM results showed that there were more scratches on the skin-contacting parts of the spectacle frames than the non-skin-contacting parts of the same frames. In the EDS findings, the mean nickel content (weight, %) of the spectacle frames was 15.7+/-5.5, and the mean chromium content was 20.3+/-3.4 at the skin-contacting parts. In the TRUE tests, nickel sulphate was the most common allergen (31 cases, 73.8%), and potassium dichromate was the second (9 cases, 21.4%). Three patients presented simultaneous positive reactions with nickel sulphate and potassium dichromate. CONCLUSION: Minor visible and non-visible fine scratches on the spectacle frames may present the provocation factors of the ACD. Nickel sulphate was the most common allergen suspected of provoking the spectacle frame-induced ACD, followed by potassium dichromate.

OBJECTIVE: The 2010 New American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria for rheumatoid arthritis (RA) was raised to identify patients with early RA and replaced the 1987 ACR classification criteria. The aims of this study are to assess the availability of new classification criteria and to evaluate its potential limitation. METHODS: A total of 408 patients with newly diagnosed RA were included from 13 secondary or tertiary hospitals in South Korea. The symptom duration was less than 12 months before the diagnosis of RA. RA was defined as either 1987 ACR classification criteria or new 2010 ACR/EULAR criteria. We compared the full details of both classification criteria. RESULTS: The mean symptom duration was 5.1 months. The majority (76.2%) of the patients were female. Two hundred and seventy three patients (66.9%) fulfilled both of the 2010 and 1987 classification criteria. Forty-seven (14.7%) of the 320 patients fulfilling the 1987 criteria did not fulfill the new classification criteria. On the other hand, eighty-eight (24.4%) of the 361 patients fulfilling the 2010 ACR/EULAR classification criteria did not fulfill the 1987 ACR criteria. Thirty-six (55.4%) of the 65 patient with seronegative RA failed to meet the 2010 classification criteria. In case of seropositive RA (n=343), 85 additional patients (24.8%) could be diagnosed as RA using new classification criteria. CONCLUSION: The new 2010 ACR/EULAR classification criteria enable physicians to diagnose more patients with early RA via the help of serology. However, the sensitivity for the diagnosis of seronegative RA is projected to decrease.

BACKGROUND: The use of light technology in dermatology has grown rapidly over the last decade, with many developments in its use for the treatment of a wide variety of skin conditions from non-melanoma skin cancers to facial resurfacing for photo-damaged skin. Light-emitting diodes (LEDs) have attracted much attention in medical fields. OBJECTIVE: (1) To assess the optimal distance of 630 nm LEDs (OmniLux(R), (Phototherapeutics Ltd, the UK)) and 830 nm LEDs (Healite(R) (Lutronic, Korea)) for maximum power as determined by a power meter and (2) to apply theory to practical use. METHODS: Two separate hinged planar light emitting diode arrays were studied: 1) the Omnilux Revive(TM) (Phototherapeutics Ltd, the UK), which delivers non-coherent red light at a wavelength of 633+/-3 nm and 2) the Lutronic Healite (Korea), which delivers non-coherent light at a wavelength of 830+/-5 nm. An X93 power meter (Gigahertz-Optik, Germany) was placed against a black background in order to reduce the amount of reflected light. We measured the LED powers over a range of 3~25 cm in 1 cm increments. RESULTS: On the irradiation side of the LED, power increases according to the mass effect of the radiation angle. However, at a certain distance, the power decline effect predominated over the amassment effect. In this respect, the LED light was estimated to be emitted in a reverse V shape. The proper irradiation distance for use in medical fields can thus be determined. CONCLUSION: The proper irradiation distance of LED will be useful and the proper use of LED under the subjects' shape will be done in many medical fields.

BACKGROUND: Inflammatory response on LPS and IFN-gamma induced Macrophage Raw 264.7 cells was secreted NO (nitric oxide) and PGE2 (prostaglandin E2) though expression of iNOS and COX-2. And many pro-inflammatory cytokines (TNF-alpha, IL-1beta, IL-6 etc.) was secreted on LPS and IFN-gamma induced Macrophage Raw 264.7 cells, too. Atopy dermatitis was inflammatory skin disease with pruritus, xeroderma and specific eczema. OBJECTIVE: We sought to effect of anti-inflammation and skin hydration of AF-343 on Macrophage Raw 264.7 cells and NC/Nga mice with Atopic Dermatitis. METHODS: The immune response of Raw 264.7 cells were induced by LPS and IFN-gamma. Then LPS and IFN-gamma induced Raw 264.7 cells was measured NO, PGE2 production after treatment of different concentrations for AF-343. The related genes (iNOS, COX-2) for NO, PGE2 production were detected using Western blot in LPS and IFN-gamma induced Raw 264.7 cells after treatment of different concentrations for AF-343. Pro-inflammatory cytokines were detected, too. NC/Nga mice as Atopy dermatitis model was induced atopy dermatitis. Then NC/Nga mice with atopy dermatitis were performed oral administration of AF-343 for 1weeks. After oral administration of AF-343, TEWL was measured on skin tissues of NC/Nga mice with atopy dermatitis according to whether were performed oral administration of AF-343 or not. And pro-inflammatory cytokines and IgE was measured in serum, protein of skin tissues of NC/Nga mice. Skin tissues of NC/Nga mice were performed H&E staining, immunohistochemical staining for PCNA, Involucrin and filaggrin. RESULTS: LPS and IFN-gamma induced Raw 264.7 cells was decreased NO, PGE2 production in dose-dependent after treatment of different concentrations for AF-343. The expression level of iNOS, COX-2 protein was decreased in dose-dependent, too. The related pro-inflammatory cytokines in media with LPS and IFN-gamma induced Raw 264.7 cells were decreased after treatment of different concentrations for AF-343. TEWL level of NC/Nga mice skin (back, ear) with atopy dermatitis according to whether were performed oral administration of AF-343 or not was decreased in NC/Nga mice with atopy dermatitis group was performed oral administration by AF-343. When NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343, induced pro-inflammatory cytokines and IgE expression in serum, protein of back, ear skin tissues of each NC/Nga mice group was decreased. H&E stained Skin tissues of NC/Nga mice was confirmed that thickness of epidermis, dermis were decreased in NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343 than NC/Nga mice group with atopy dermatitis. The expression of PCNA, involucrin and filaggrin were decreased in NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343 than NC/Nga mice group with atopy dermatitis as results of immunihistochemical staining using specific antibodies such as PCNA as cell proliferation marker, involucrin and filaggrin as keratinocytes differentiation markers for skin tissues (back, ear) of NC/Nga mice. CONCLUSION: We confirmed effect of anti-inflammation and skin hydration of AF-343 on Macrophage Raw 264.7 cells and NC/Nga mice with Atopic Dermatitis. In conclusion, AF-343 is expecting as therapeutics for atopic dermatitis.

BACKGROUND: The imaging system that's currently being used in the field of dermatology is based on such instruments as the dermoscope, phototrichograph and camera. In recent years, the use of an image magnification system based on polarization has become popular. OBJECTIVE: In this study, optical quantification was performed based on the multiwavelength imaging analysis of the structures that form dermatologic diseases, and an attempt was made to enhance the image quality by using polarization technology. METHODS: The lesions of three patients who were clinically diagnosed with cherry angioma, melanocytic nevus and inflammatory lesions in acne and freckles were measured at the outpatient clinic of the Department of Dermatology of the authors' hospital. All the patients were female, and their mean age was 29.3 years. RESULTS: The optical characteristics of the patients' various skin lesions, including cherry angioma, melanocytic nevus and inflammatory lesions in acne and freckles, were distinguishable by their wavelength. CONCLUSION: The use of different kinds of information may be helpful for measuring and diagnosing various skin lesions that have not been differentiated with using the previous modalities. Further, if the various environmental factors that may be generated during the measurement process can be controlled, then these study results can be applied to a standard diagnostic modality in the field of dermatology.

A two-month-old baby had acholic stool, neonatal hyperbilirubinemia and congenital heart disease. Atresia of the hepatic duct was confirmed by open cholangiography, which showed a non-opacified intrahepatic bile duct. Liver biopsy and the Kasai operation were performed. Because the liver biopsy pathology revealed a paucity of intrahepatic bile ducts, the patient was diagnosed with the Alagille syndrome. We report the case of an infant diagnosed with the Alagille syndrome with atresia of the hepatic duct.
