The fibrofolliculoma is characterized by abnormal hair follicles with epithelial strands extending out from the infundibulum of the hair follicle into a hyperplastic mantle of specialized fibrous tissue. We have seen a peculiar case of a 1 year and 2 months old male who had a solitary papule on the left side of his face which histologically showed a typical fibrofolliculoma pattern.

Recently the alanine/valine (A/V) polymorphism of the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, one of the key enzymes catalyzing remethylation of homocysteine, has been reported to its association with coronary artery disease. lhe homozygous of C677T mutation (VV genotype) correlates with increased plasma homocysteine levels as a result of the reduced activity and increased thermolability of MTHFR. We investigated whether this rnutation and homocysteine influence risk for coronary artery disease (CAD) in normal control subjects and CAD patients and two risk groups, A (>2 risk factors) and B (<1 risk factor). The MTHFR genotype and plasma homocysteine were determined by PCR followed by HinA digestion and high performance liquid chromatography (HPLC) system, respectively. From this study, statistical significance of V mutation of MTHFR between four groups was not found. Homocysteine level was the highest in CAD patients and the lowest in risk group B. Plasma homocysteine level in VV genotype of CAD patients was significantly higher than in other two genotypes and normal control subjects. We concluded that homozygisty for the C677T mutation of MTHFR was not an independent risk factor of CAD but associated with a prediposition to increased plasma homocysteine levels in CAD patients.

BACKGROUND: Fundus photographs performed during health check-up were reviewed to determine the usefulness in mass screening. METHODS: Subjects consistine of 3017 people who had undergone physical health check up at the Health Clinic, Dong-Eui Medical Center in 1997 and whose fundus photographs of both eyes were taken showing clearly visible posterior pole and optic disc were chosen as subjects. Medical records which included cases of reported close exam and causes, actual cases of close exam and final diagnoses. RESULTS: Of the 3017 people, reported close exam was performed in 665 (22.0%). Among them glaucoma was suspected in 460 retinal hemorrhagic lesion in 63, retinal degenerative lesion in 67 and others in 75. There were 187 actual cases(28.1%) of close exam including glaucoma suspect in 79, retinal hemorrhagic lesion 47, retinal degenerative lesion 34 and others 27. Among 187 actual cases of close exam, 140 people (1.3%) were eventually diagnosed as glaucoma suspect (60), retinal hemorrhagic lesion (38), retinal degenerative lesion (21) and others (21). CONCLUSIONS: Fundus photographs are useful in mass screening, but performing close exam to enhance the usefulness of the fundus photographs is necessary.

Prader-Willi(PW)syndrome is characterized by obesity, hypotonia, mental retardation, hypogonadism, short stature, excessive eating and characteristic facial appearance. Diabetes mellitus has been considered a component of PW syndrome. Recently this syndrome is caused by the absence of paternally derived genes normally located on chromosome segment 15 q11-q13 or may be the result of maternal uniparental disomy with the absence of paternally derived 15 q11-q13 region. The developement of probes containing segments of DNA from chromosome region 15 q11-q13 provides the oppotunity to confirm the diagnosis of PW syndrome by fluorescence in situ hybridization(FISH). We experienced a 15-year-old boy of PW syndrome with diabetes mellitus, who revealed mental retardation, hypogonadism, obesity and microdeletion of chromosome 15 q11-q13 comfirmed by FISH.

PURPOSE: To verify the association between cigarette smoking and bladder cancer in the Korean population, as smoking is well known as a risk factor on bladder cancer. The risk of bladder cancer was compared among never-smokers, ex-smokers and current-smokers using a multivariate adjusted incidence rate and the mortality rate of bladder cancer of Koreans. MATERIALS AND METHODS: A total of 348,010 participants were enrolled in this prospective study between 1993 (to 1994) and 2002. All participants completed a self administered questionnaire on cancer risk factors, including smoking habit. Follow up for incident bladder cancer was established. We classified all participants into three categories: current-smoker, ex-smoker and never-smoker, on the basis of their smoking habits. We confirmed bladder cancer from the data of the Korea National Cancer Registry and National Health Insurance Corporation up to (December?) 2002. The multivariate adjusted incidence and the mortality due to bladder cancer were used for both genders for a statistical analysis using a Cox proportional hazards model. RESULTS: The incidence rate of bladder cancer per 100,000 persons in male never-smokers, ex-smokers and current-smokers were 27, 41 and 48, respectively, and the multivariate adjusted relative risks (RR) were 1.3 (95% confidence interval (CI), 0.9-2.0) and 1.7 (95% CI, 1.2-2.3) in ex- and current smokers, respectively. The incidence rate of bladder cancer in women was 4.7, 8.4 and 13, respectively. There was no significant association between the risk of bladder cancer and the amount and duration of smoking. CONCLUSIONS: We concluded that current smokers have an increased incidence and mortality rate of bladder cancer in both genders in the Korean population, but there was no significant difference in relation to the amount and duration of smoking.

Acute suppurative thyroiditis is a rare because of high resistance to bacterial infection of thyroid gland, which is rich vascularity and lymphatic drainage, a high iodine content and complete encapsulation. The common clinical manifestations are fever, neck pain and localized mass of thyroid area. This thyroiditis is more common in left thyroid lobe. The most important causal microorganism are staphylococci and streptococci, with frequent isolation of mixed flora and anaerobes. Diagnosis was easily made by typical clinical manifestation, ultrasonography, thyroid imaging and fine needle aspiration. Treatment usually consist of appropriate antibiotic therapy and surgical drainage when abscess formation develops. We report a typical case of acute suppurative thyroiditis in 1 year old female infant with brief review of literatures.

BACKGROUND: It has become generally accepted that cigarette smoking contributes to accelerated coronary and peripheral vascular disease, pulmonary fibrosis and periodontal disease. Moreover, it has been postulated that cigarette smoking causes skin-aging. Many of cutaneous manifestations of nicotine which is a major component of the particulate phase of tobacco smoke are related to its vasoconstrictive and thrombotic effects on the peripheral vascular system. How-ever, direct effect of nicotine on extracellular matrix (ECM) proteins including collagens is not well established. OBJECTIVE: To evaluate the effect of nicotine on type I collagen gene expression in cultured human skin fibroblasts. METHODS: After exposure to different doses of nicotine on cultured human skin fibroblasts, we examined the expressions of α1(I) procollagen gene and fibronectin gene by Northern blot analysis and chloramphenicol acetyltransferase (CAT) assay with CAT construct containing the 3.5 kb COL1A2 promoter. RESULTS: In Northern blot hybridization, steady-state levels of α1(I) procollagen mRNA were decreased 0.8-fold at 1 µg/mL of nicotine, 0.5-fold at 10 µg/mL and 0.2-fold at 100 µg/mL, compared to untreated control. Those of fibronectin mRNA were decreased 0.9-fold, 0.7-fold, and 0.3-fold, respectively. In CAT assay, the relative COL1A2 CAT activity was 1.0 in the untreated control, 0.7 at a concentration of 1 µg/mL of nicotine, 0.5 at 10 µg/mL, and 0.3 at 100 µg/mL. CONCLUSION: These results indicate that nicotine is a down-regulator of collagen gene expression at transcriptional level in vitro. We speculate that nicotine may contribute to the skin-aging by modulation of extracellular matrix gene expression including collagen as well as by its vasoconstrictive and thrombotic effects.
