Background: Solar urticaria is an uncommon photodermatosis characterized by the appearance of wheals after sun exposure. Although many sporadic cases have been reported, little is known about the clinical characteristics in Korean patients. Objective: The purpose of this study was to investigate the clinical characteristics of solar urticaria in Korean patients, with an emphasis on demographic characteristics and action spectrum. Methods: A retrospective analysis was conducted of the records of patients phototested at Seoul National University and subsequently diagnosed with solar urticaria. Results: A total 11 solar urticaria patients were used in this study. The mean age was 24 years. Nine (82%) patients were male and two patients (18%) were female. The mean age of onset was 20.8 years. The mean exposure time to wheal formation was 24 minutes and mean duration of wheal was 98 minutes. The action spectra of solar urticaria were visible light for 6 (55%) patients, ultraviolet A (UVA) for 2 (18%), both visible light and UVA for one (9%), both visible light and UVB for one, and natural sunlight for one. Conclusion: Visible light was the most common action spectrum in this study. Our findings illustrate the clinical and photobiological characteristics of solar urticaria in Korean patients.

Paclitaxel is one of the taxoid-antineoplastic agents. These agents are used in the treatment of breast, lung and ovary cancer. Nail changes due to treatment with the taxanes (mainly docetaxel) are reported in 30∼40 percent of patients. Paclitaxel is not commonly associated with dermatological reactions, although localized skin reactions and tissue necrosis following extravasation have been reported. Reports of the incidence of nail changes associated with paclitaxel is noted as the pigmentation or discoloration of the nail bed, vary from 2∼20%. We report a patient with onycholysis and subungual suppuration during treatment with paclitaxel. (Korean J Dermatol 2008;46(2):278∼280)

In January 2006, Sunitinib was approved by the US Food and Drug Administration for the treatment of advanced renal cell carcinoma and gastrointestinal stromal tumor. Sunitinib inhibits the receptor tyrosine kinases that are involved with various receptors whose functions are related to tumor growth, angiogenesis and metastatic progression. The cutaneous adverse reactions of hand-foot syndrome associated with sunitinib are well known, but there have been no previous reports on these reactions in the Korean medical literature. We report here on a case of hand-foot syndrome due to this drug, and we discuss the possible mechanism of hand-foot syndrome caused by sunitinib. (Korean J Dermatol 2008;46(10):1384∼1386)

Research on enhancing the mechanical strength, lightweight properties, electrical conductivity, and thermal conductivity of composite materials by incorporating nano-materials is actively underway. Thermoplastic resins can change their orm under heat, making them highly processable and recyclable. In this study, Polyamide-Nylon 6 (PA6), a thermoplastic resin, was utilized, and as reinforcing agents, fused carbon nano-materials (FCN) formed by structurally combining Carbon Nanotube(CNT) and Graphene were employed. Nano-materials often face challenges related to cohesion and dispersion. To address this issue, Silane functional groups were introduced to enhance the dispersion of FCN in PA6. The manufacturing conditions for the composite materials involved determining the use of a dispersant and varying FCN content at 0.05 wt%, 0.1 wt%, and 0.2 wt%. Tensile strength measurements were conducted, and FE-SEM analysis was performed on fracture surfaces. As a result of the tensile strength test, it was confirmed that compared to pure PA6, the strength of the polymer composite with a content of 0.05 wt% was improved by about 60%, for 0.1 wt%, about 65%, and for 0.2 wt%, the strength was improved by 50%. Also, when compared according to the content of FCN, the best strength value was shown when 0.1 wt% was added. The elastic modulus also showed an improvement of about 15% in the case of surface treatment compared to the case without surface treatment, and an improvement of about 70% compared to pure PA6. Through FE-SEM, it was confirmed that the matrix material and silane-modified nanomaterial improved the dispersibility and bonding strength of the interface, helping to support the load evenly and enabling effective stress transfer.

Background: Coronary artery disease (CAD) has recently become one of the major causes of mortality and morbidity in Korea. However, not much epidemiologic and demographic data has yet been reported. The purpose of this study was to investigate the clinical features as well as the prognostic factors of patients with CAD. Methods: We prospectively enrolled 1,665 consecutive patients with CAD who had been admitted to the Catholic University Hospitals from December 1999 to April 2003. Results: Acute myocardial infarction (AMI) was the most common cause of admission (n=715, 42.9%). Dyslipidemia, hypertension and smoking were the most common risk factors. More than 70% of the patients who underwent percutaneous coronary intervention (PCI) received stent implantation. A total of 965 (612 males) patients were followed at least for 6 months (the mean follow-up duration was 23.8±12.2 months). The incidence rates of major adverse cardiac events (MACE: cardiac death, acute myocardial infarction, target vessel revascularization) and cardiac death were 15.1% (n=146) and 2.2% (n=21), respectively. There was no difference in overall survival between the patients treated with medical therapy and those treated with PCI. By Cox regression analysis, the independent prognostic factors for MACE were PCI (95% CI: 1.75-4.85; p<0.01) and multivessel disease (95% CI: 1.03-2.04; p<0.05), and the independent prognostic factors for cardiac death were medical therapy (95% CI: 1.08-14.41; p<0.05) and old age (95% CI: 1.13-16.13; p<0.05). Conclusions: There was no difference in overall survival between the patients treated with medical therapy and those treated with PCI. However, PCI was superior to medical therapy for preventing death of the patients with acute coronary syndrome.(Korean J Med 73:142-150, 2007)

To produce activated carbon fibers, the process is carried out through either physical activation method or chemical activation method. In this study, we present the results regarding the characteristics of activated carbon fibers manufactured under various conditions through the quantitative control of steam. The yield after activation indicates a decreasing trend with the increase in steam quantity and activation time. Additionally, specific surface area characteristics exhibit variations based on activation time and steam flow rate. The SEM analysis results reveal that higher steam flow rates lead to the presence of both mesopores and macropores on the surface of activated carbon fibers (ACF).
