We experienced a case of arteriovenous hemangioma showing Dariers sign on the forehead of a 43-year-old man. He presented with a single, 1 * 1.5cm sized, violaceous, asymptomatic nodule with a history of an intermittent wheal at the lesional site. This skin lesion showed Dariers sign clinically and proliferation of mast cells histopathologically with the punch biopsy specirnen suggesting urticaria pig- mentosa. Howerer, we could diagnose it as a arteriovenous hemangioma on complete excision, as the specimen showed arteriovenous proliferation with increased mast cells in a perivascular pattern. This case showed confusing clinical signs and showed the importance of complete excision for the diagnosis of a small skin tumor especially when a vascular proliferating tumor is suspected.

BACKGROUND AND OBJECTIVES: Mast cell is a key cell in the pathogenesis of allergic rhinitis. It is expected that apoptosis of mast cell is an important step that can lead to treatment of allergic rhinitis. Meanwhile, the cyclosporin A (CsA) is immunosuppresant agent to inhibit the action of various immune cells. The purpose of this study is to identify whether CsA directly induces apoptosis of mast cells in vitro. MATERIALS AND METHOD: After the culture of p815 cells, mouse mastocytoma cells, the cells were treated with 1 micrometer, 2 micrometer, 5 micrometer, and 10 micrometer CsA, and then LD50 of p815 cells were calculated by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay. For identification of apoptosis of p815 cells, electrophoresis and flow cytometry after CsA treatment were done and morphological changes in light microscope was observed. We also quantified apoptotic cells by TUNEL assay and Hoechst stain. RESULTS: The LD50 of p815 cells is 9.87 micrometer after CsA treatment during 24 hours, 6.11 micrometer during 48 hours and 6.21 micrometer during 72 hours. With the higher concentration of CsA treatment, the greater effect on apoptosis of p815 cells was revealed. We observed laddering pattern for DNA fragmentation in electrophoresis. Nuclear fragmentation and chromatin condensation of p815 cells was observed under the light microscope. Results of flow cytometry were similar to the MTT assay results. Quantification of apoptotic p185 cells by TUNEL assay and Hoechst stain were calculated. CONCLUSION: Apoptosis of mast cells can be induced by CsA treatment in vitro.

Primary sternal osteomyelitis (PSO) is a rare condition that may develop without any contiguous focus of infection. Due to the rarity of the disease, early diagnosis and appropriate treatment are often delayed. Herein, we describe a patient with PSO caused by Staphylococcus aureus that presented with chest pain and fever. The patient had no predisposing factors for sternal osteomyelitis. The chest pain was thought to be non-cardiogenic, as electrocardiography and cardiac enzyme did not reveal ischemic changes when he visited the emergency room. After blood culture revealed the presence of S. aureus, every effort was made to identify the primary focus of infection. Bone scan and magnetic resonance imaging revealed osteomyelitis with soft tissue inflammation around the sternum. After 8 weeks of antibiotics treatment, the patient recovered without any complications.

OBJECTIVES: This study was conducted to investigate the possibility of neurological soft signs as an endophenotype for schizophrenia by examining neurological soft signs in patients, their unaffected siblings and normal comparison subjects. METHODS: The study sample consisted of 32 patients, 25 of their unaffected siblings and 30 normal comparison subjects. Neurological soft signs were evaluated using the Cambridge Neurological Inventory Part 2. soft sign assessment. RESULTS: The patients were significantly more impaired than normal comparison subjects (p = 0.047) on primitive reflex. The patients were significantly more impaired than siblings (p = 0.004) and normal comparison subjects (p = 0.021) on motor coordination. The siblings performed better on sensory integration than the patients (p = 0.020) and normal comparison subjects (p = 0.036). CONCLUSIONS: This study suggests that neurological soft signs might be a potential biomarker for schizophrenia, but might not be an endophenotype for schizophrenia.

BACKGROUND: Osteoporosis and its related fractures are increasingly being recognized as major health problems because of the rapidly increasing elderly population. In this study, we investigated the annual trend of osteoporosis-related health services utilization. METHODS: Participants aged over 50 years were identified from the Korean National Health Insurance Service database between 2008 and 2012. Health service utilization rate and treatment rate were calculated through the operational definition. RESULTS: In this period, the number of osteoporosis patients, aged over 50 years, using the medical service, increased by 33.2%. This increase was higher in males than in females. Moreover, the number of newly diagnosed osteoporosis patients increased by 4.3% in women and 20.4% in men. To estimate the proportion of osteoporosis patients who utilize medical services, we analyzed prevalence data from the Korea National Health and Nutrition Examination Survey from 2008 to 2010. Less than 60% of patients with osteoporosis were estimated to have utilized medical services because of osteoporosis. Drug treatment rates were 34.1%, 31.1%, and 33.5% in 2008, 2009, and 2010, respectively. CONCLUSION: This study demonstrated an increasing trend in the utilization of the osteoporosis-related health services from 2008 to 2012 in Korea. The proportion of newly diagnosed osteoporosis patients and the prevalence of access to medical services increased more in men than in women. Therefore, an increasing need for prevention and treatment of male osteoporosis was observed. The osteoporosis treatment rate was lower than that for other chronic diseases; more efforts are needed to improve awareness regarding osteoporosis treatment.

BACKGROUND: Sexual dysfunction such as erectile dysfunction (ED) may be a hidden agenda, but, it should be dealt with by family physicians in primary care. We investigated the prevalence of ED and utilization of sexual consultation practice among community family physicians. METHODS: We analyzed the subjects who were males aged over 30 and married who visited 10 community family clinics around Seoul, Korea and completed questionnaires related to erectile function and utilization of sexual consultation service from May 9 to 28 2009. ED was designated if the 5-item version of international index of erectile dysfunction (IIEF-5) scores were less than 17. RESULTS: The average age of the responders was 45.6 years. The prevalence of ED was 43.3% and increased according to age, chronic disease, low educational history and low family income. Almost all of the mild ED patients answered that they needed sexual consultation. But, half of them had no plan to have a sexual consultation. Odds ratios (ORs) with 95% confidence intervals (CIs) for having a sexual consultation or not according to variables were calculated with logistic regression. More severe ED (OR = 0.875; 95% CI, 0.827 to 0.926), existence of chronic disease (OR = 1.828; 95% CI, 1.026 to 3.260), inferior education (OR = 0.395; 95% CI, 0.196 to 0.796), and lower income (OR = 0.326; 95% CI, 0.124 to 0.857) were the factors which influenced to have a sexual consultation with a family physician. CONCLUSION: The prevalence of ED in family clinic was over 40%, but the utilization of sexual consultations was under 50%. We need to develop intervention strategies for more sexual counseling practice according to educational history, family incomes and status of ED in community family medicine clinics.

Among the 98 patients who underwent operations for thoracolumbar spinal lesions from May 1989 to September 1994, the authors performed clinical analysis of 72 patients who were followed-up for more than 12 months. There were 52 cases of trauma, 18 cases of tuberculous spondylitis, and 2 cases of metastatic tumor. After partial or toal vertebrectomy, interbody fusion was performed using autogenous iliac bone or autogenous ribs which were taken while approaching the thoracic spine, and stabilized using Kaneda devices. Complete neural decompression was possible under direct vision in all cases. Neurologic deficits improved to an average of 1.7 grades using a modified Frankel scale. Patients with tuberculous spondylitis did not show recurrence or any evidence of increased risk of secondary infection caused by instrumentation. Loosening or breakdown of instruments occurred in 4 patients, and spinal deformity in 7 patients, but reoperation was not needed in any of these patients. By anterior decompression, interbody fusion and stabilization using Kaneda device in thoracolumbar spinal lesions, we could obtain satisfactory neurologic improvement as well as immediate firm stability and high fusion rate involving only a minimum(usually two) number of motion segments as compared with the posterior approach.

PURPOSE: The TNM classification for carcinoma of the colon and the rectum provides more detail than other staging systems. This study was performed to evaluate the effectiveness of AJCC staging system (5th ed., 1997) for the colorectal cancer in predicting prognosis. METHODS: We analyzed a data base of 1,233 colorectal cancer patients (M:F=673:560) who underwent surgery in Asan Medical Center during July 1989-December 1996. Survival analysis was performed between the stages and the subgroups in same stage by using Kaplan-Meier method and log rank test. Borderline subgroup comparison between the stages was performed, also. Significance was assigned to a P value of <0.05. RESULTS: Mean age of the patients was 57 (19-90) years old. Median follow-up period was 42 (6-129) months. The number of patients in each stage were 0: 15, I: 152, II: 390, III: 465, IV: 199. The 5 year overall & disease free survival rates of each stage were 100%, 100% (in stage 0), 96.4%, 93.6% (in stage I), 82.7%, 82.2% (in stage II), 59.9%, 55.3% (in stage III), and 7.3%, 24.9% (in stage IV), respectively (P=0.000). Subgroup analysis in stage I (T1N0 vs. T2N0) and II (T3N0 vs. T4N0) revealed no differences. However, in stage III, N1 (n=246) group showed better survival than N2 (n=219) group (70.3%, 65.5% vs. 49.2%, 44.6%: P=0.000). Borderline survival analysis between stage I and II (T2N0 vs. T3N0) was significantly different (96.6%, 95.7% vs 82.7%, 82.3%: P=0.006). However, between stage II and III (T4N0 vs. T1N1), appropriate analysis was impossible due to small number of cases. CONCLUSIONS: AJCC staging system for colorectal cancer was reliable and effective in predicting prognosis. However, substages are needed in stage III.
