Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors. More than half (59.3%) patients were previously treated by non-dermatologists or self-treated. The mean duration of TI was 15.0 +/- 25.3 months. The most common clinical manifestations were eczema-like lesion, psoriasis-like, and lupus erythematosus-like lesion. The trunk and face were frequently involved, and 91 patients (32.2%) also had coexisting fungal infections. Among 67 isolated strains, Trichophyton rubrum was the most frequently detected (73.1%). This is the largest study of TI reported to date and the first investigational report concerning TI in Korea. We suggest that doctors should consider TI when a patient has intractable eczema-like lesions accompanied by tinea pedis/unguium. Furthermore, there should be a policy change, which would make over-the-counter high-potency topical steroids less accessible in some countries, including Korea.

Advanced hepatocellular carcinoma (HCC) has a poor prognosis and few effective therapies. Recently, low-dose antiangiogenic (also called metronomic) chemotherapy has been tested in patients with advanced HCC. Here, we report two patients with advanced HCC who showed a good response after metronomic chemotherapy. The first was a 54-year-old man who was diagnosed with advanced HCC with lung metastasis. After three cycles of metronomic chemotherapy, the size of tumor and pulmonary metastatic lesions had decreased markedly on follow-up computed tomography. The second was a 54-year-old woman who was diagnosed with HCC with portal vein thrombosis. Metronomic therapy was performed. After 9 months, tumor enhancement in the arterial phase had disappeared completely, and the portal vein thrombus was decreased slightly. Metronomic therapy is an interesting treatment option for patients with advanced HCC. More clinical data and studies are needed to confirm this result.

BACKGROUND: This study evaluated the clinical characteristics and risk factors associated with community and hospital onset MRSA isolated from patients admitted to a tertiary care teaching hospital. METHODS: The study was carried out on MRSA isolated from clinical specimens of patients admitted into the wards and the intensive care unit in a 2,200-bed tertiary care teaching hospital from January 1st through December 31st, 2007. In order to identify the risk factors associated with MRSA acquisition, the medical records were reviewed. All statistics were computed using SPSS version 14.0. RESULTS: Of the 835 MRSA isolates, 179 (21.4%) were CO-MRSA and 656 (78.6%) were HO-MRSA. Of the 179 CO-MRSA isolates, 6 (3.4%) were CA-MRSA. Multiple logistic regression analysis showed that a history of using medical device or antibiotics within 1 year before the isolation of MRSA were significant risk factors for HO-MRSA, and a history of hospitalization within 1 year before the isolation of MRSA was a significant risk factor for CO-MRSA. Analysis on the antibiotics administered within 1 year before the isolation of MRSA showed that levofloxacin, macrolides, 1st generation cephalosporins, 3rd generation cephalosporins, 4th generation cephalosporins, vancomycin, metronidazole, and carbapenem were all significant risk factors for HO-MRSA and that TMP/SMX was a significant risk factor for CO-MRSA. Of the 6 (3.4%) CA-MRSA isolates, 1 (16.7%) was the pathogen responsible for soft tissue infection. No patients died from the CA-MRSA infection. CONCLUSION: MRSA isolated from clinical specimens of patients admitted into the wards and the ICU in a tertiary care teaching hospital was usually HO-MRSA, CO-MRSA and HO-MRSA usually had at least one of the risk factors associated with MRSA acquisition, and CO-MRSA was mainly HACO-MRSA.

PURPOSE: For the first time, a nationwide survey in the Republic of Korea was conducted to determine the basic parameters for the treatment of esophageal cancer and to offer a solid cooperative system for the Korean Pattern of Care Study database. MATERIALS AND METHODS: During 1998~1999, biopsy-confirmed 246 esophageal cancer patients that received radiotherapy were enrolled from 23 different institutions in South Korea. Random sampling was based on power allocation method. Patient parameters and specific information regarding tumor characteristics and treatment methods were collected and registered through the web based PCS system. The data was analyzed by the use of the Chi-squared test. RESULTS: The median age of the collected patients was 62 years. The male to female ratio was about 91 to 9 with an absolute male predominance. The performance status ranged from ECOG 0 to 1 in 82.5% of the patients. Diagnostic procedures included an esophagogram (228 patients, 92.7%), endoscopy (226 patients, 91.9%), and a chest CT scan (238 patients, 96.7%). Squamous cell carcinoma was diagnosed in 96.3% of the patients; mid-thoracic esophageal cancer was most prevalent (110 patients, 44.7%) and 135 patients presented with clinical stage III disease. Fifty seven patients received radiotherapy alone and 37 patients received surgery with adjuvant postoperative radiotherapy. Half of the patients (123 patients) received chemotherapy together with RT and 70 patients (56.9%) received it as concurrent chemoradiotherapy. The most frequently used chemotherapeutic agent was a combination of cisplatin and 5-FU. Most patients received radiotherapy either with 6 MV (116 patients, 47.2%) or with 10 MV photons (87 patients, 35.4%). Radiotherapy was delivered through a conventional AP-PA field for 206 patients (83.7%) without using a CT plan and the median delivered dose was 3,600 cGy. The median total dose of postoperative radiotherapy was 5,040 cGy while for the non-operative patients the median total dose was 5,970 cGy. Thirty-four patients received intraluminal brachytherapy with high dose rate Iridium-192. Brachytherapy was delivered with a median dose of 300 cGy in each fraction and was typically delivered 3~4 times. The most frequently encountered complication during the radiotherapy treatment was esophagitis in 155 patients (63.0%). CONCLUSION: For the evaluation and treatment of esophageal cancer patients at radiation facilities in Korea, this study will provide guidelines and benchmark data for the solid cooperative systems of the Korean PCS. Although some differences were noted between institutions, there was no major difference in the treatment modalities and RT techniques.

Condyloma acuminatum (CA) is a common sexually transmitted disease caused by the human papillomavirus. In gastrointestinal practice, we generally encounter this disease in the anal canal but rarely in the rectum during a colonoscopy. There are many therapeutic options for CA including chemical or physical destruction, immunological therapy, or a surgical excision. All these procedures have some degree of limitations such as limited clearance rate, high recurrence rate, long duration of therapy, bleeding, release of potentially infectious aerosols, scarring etc. With argon plasma coagulation (APC), which is more available than lasers in gastrointestinal practice, a high frequency current flows through the argon plasma to the tissue, allowing well-controlled superficial tissue destruction without any direct contact between the probe and the tissue. We present a case of anal CA that was treated successfully with APC during a colonoscopy with no recurrence during the follow up.

BACKGROUND: Coenzyme Q10 is an endogenous lipid soluble antioxidant that scavenges reactive oxygen species (ROS) directly, inhibits biomolecule oxidation, and affects antioxidant defense in vivo. Kinetin (N6-furfuryladenine) belongs to the family of N6-substituted adenine derivatives known as cytokinins. Kinetin also exerts anti-aging effects. Commercial products of coenzyme Q10 and kinetin are developed and are selling as a rejuvenating drug. However, the action mechanisms of kinetin are not fully known, though it has been suggested to act both as an inhibitor of reactive oxygen species (ROS) formation and as a scavenger of ROS. Thioctic acid (alpha-Lipoic acid), which becomes a powerful antioxidant in its reduced form, has been suggested as a dietary supplement to treat diseases associated with excessive oxidant stress. Exposure of the skin to ultraviolet (UV) radiation, particulary UVB (290-320nm), causes adverse biological effects, including alterations in cutaneous immune cells, photoaging and photocarcinogenesis. Several studies have shown that coenzyme Q10, kinetin, and thioctic acid afforded the protection effects against UVB-induced inflammatory responses and photoaging. Objective and Method: In this study, we investigated the effects of coenzyme Q10, kinetin and thioctic acid on UVB irradiated human skin fibroblasts using a viability test, thiobarbituric acid assay and Northern blot analysis. RESULT: Cell survival curves after UVB irradiation showed a dose dependent decremental pattern by trypan blue exclusion assay. Only 30% of dermal fibroblasts survived at 150mJ/cm2 UVB irradiation. The damage was associated with cell membrane lipid peroxidation, as shown by accumulation malondialdehyde (MDA). By pre-cultivation with coenzyme Q10, kinetin and thioctic acid, a significant protection effect was noted as an increase in the absolute number of surviving cells and marked decrease in the levels of MDA. CONCLUSION: Coenzyme Q10, kinetin, and thioctic acid, which have been newly accepted as having UV protection properties, are effective membrane peroxidation inhibitors and inhibitors of reactive oxygen species (ROS) formation and scavenger of ROS.

PURPOSE: Current results of autologous stem cell transplantation (SCT) suggest that this procedure may prolong disease free survival in patients with acute myeloid leukemia (AML). Autologous SCT is increasingly used as treatment for AML in first remission. The aim of this study was to evaluate the outcome of autologous SCT for patients with AML in first remission treated by autologous SCT using cytarabine, melphalan and total body irradiation (TBI) as the conditioning regimen. MATERIALS AND METHODS: Between January 1995 and December 1999, 29 patients with AML in first remission underwent autologous SCT. The median age of patients was 33 years (range, 16 to 47). The conditioning regimen consisted of cytarabine (3.0 gm/m2 for 3 days), melphalan (100 mg/m2 for 1 day) and TBI (total 1000 cGy in five fractions over 3 days). RESULTS: The median follow up was 40 months with a range of 3 to 58 months. The 4-year cumulative probability of disease free survival was 69.0%, and median survival was 41.5 months. The 4-year relapse rate was 27.6%. The factor influencing disease free survival and relapse rate was the French-American-British (FAB) classification (M3 group vs. other groups; p=0.048, p=0.043). One patient died from treatment-related toxicity. CONCLUSION: Although the small number of patients does not allow us to draw any firm conclusion, our results were encouraging and suggest that the association of cytarabine, melphalan and TBI as a conditioning regimen for autologous SCT for AML in first remission appears to be safe and effective.

OBJECTIVE: The authors present the effect of VEGF upon neuronal and glial response following transient global ischemia of the rat METHODS: We studied the effect of VEGF in 36 rats subjected to 15 minutes of transient global ischemia. Animals were devided into control group(transient global ischemia only: day-3, day-7, day-14, respectively n=6) and VEGF-treated group(transient global ischemia with intraventricular injection of 100 micro gram VEGF: day-3, day-7, day-14, respectively n=6). These animals were sacrificed at 3 days, 7 days and 14 days after induction of ischemia. Nissle stain and immunohistochemistry of GFAP(glial fibrillary acidic protein), OX-42, and ED1 were done for assessment of neuronal and glial responses. RESULTS: In the CA1 hippocampus, there was a significant reduction of pyramidal cell damage in VEGF-treated group as compared with control group in post-ischemia 3, 7, 14 days(p<0.05). In the CA3 hippocampus which is relatively resistant to ischemia, reduction of pyramidal cell damage was significant in post-ischemia 7 days(p<0.05), not significant in post-ischemia 3, 14 days(p>0.05). In the assessment of CA1 hippocampus with GFAP stained areas, there was significant reduction of reactivity in post-ischemia 3, 7 days(p<0.05), not significant in post-ischemia 14 days(p>0.05). In the CA3 hippocampus, reduction of GFAP reactivity was significant in post-ischemia 3, 7 days(p<0.05), not significant in post-ischemia 14 days(p>0.05). In the assessment of CA1 hippocampus with OX-42 stained areas, there was significant reduction of reactivity in post-ischemia 3, 7, 14 days(p<0.05). But in the CA3 hippocampus, the difference was not significant in post-ischemia 3, 7 days(p<0.05). In the assessment of of CA1 hippocampus with ED1 stained areas, there was significant reduction of reactivity in post-ischemia 3, 7, 14 days(p<0.05). But in the CA3 hippocampus, the difference was significant in post-ischemia 3 days only(p<0.05). CONCLUSION: These results suggest that VEGF can reduce neuronal damage in transient global ischemia, thus have protective effect on ischemic brain injury. In our experiment, the reduction of glial response with VEGF seems to be related to the secondary neuroprotective effect of VEGF. However, the proliferation of endothelial cells and new vessel formation take days to months, the thus neuroprotective effect of VEGF against ischemia seems to related to a certain mechanism rather than angiogenesis.

Spinal cord compression, an oncologic emergency, is a rare complication of hematologic malignancy. Our experience was obtained with a series 32 patients following retrospective analysis for assessing the role of radiation therapy and identifying the prognostic factors affecting on treatment outcome. Diagnosis was usually made by means of radiologic study such as myelography or computerized tomography (CT) or magnetic resonance imaging (MRI) and neurologic examination. Five cases were diagnosed by subjective symptom only with high index of suspicion. In 31 cases, the treatment consisted in radiation therapy alone and the remained one patient had laminectomy before radiation therapy because of diagnostic doubts. Total treatment doses ranged from 800 cGy to 4000 cGy with median of 2999 cGy. Initially large fraction size more than 250 cGy were used in 13 patients with rapidly progressed neurologic deficit. The clinical parameters considered in evaluating the response to treatment were backache, motor-sensory performance and sphincter function. Half on all patients showed good response. Partial response and no response were noted in 37.5% and 12.5%, respectively. Our results showed higher response rate than those of other solid tumor series. The degree of neurologic deficit an that time of diagnosis was the most important predictor of treatment outcome. The elapsed time from development of symptoms to start of treatment was significantly affected on the outcome. But histology of primary tumor, total dose and use of initial large fraction size were not significantly affect on the outcome. These results confirmed the value of early diagnosis and treatment especially in radiosensitive hematologic malignancy.
