Angioma serpiginosum is a rare acquired naevoid disorder, characterized by minute red or purple punta that are frequently arranged in serpiginous patterns in the lower extremities and buttocks. It usually begins in childhood and is more common in females. Histopathologically, thin-walled capillaries in the dermal papillae and the superficial reticular dermis are widely dilated without extravasation of red blood cells. We report a case of angioma serpiginosum on the lateral aspect of the right arm along the lines of Blaschko in a 36-year-old woman.

BACKGROUND: Drug reactions are common problems in hospital inpatients and outpatients. Reliable diagnosis is essential but often difficult. OBJECTIVE: This study attempts to define the clinical features and causative drugs in the patients with drug eruptions, and to evaluate the diagnostic value of skin tests. METHODS: Sixty one patients with drug eruptions were reviewed clinically. In 18 patients, patch and prick tests were performed using suspected drugs. RESULTS: 1. The highest incidence of drug eruptions was observed in the third and forth decades(44.2%) and there was no sexual prodominence. 2. The most frequent latent peroid was 4 hours to 1 week(49.2%). 3. The common morphological features were exanthematous eruptions(57.3%), urticaria(14.8%) and fixed drug eruptoins(11.5%). 4. The major causative drugs were antibiotics(cephalosporin, ampicillin), antipyretics/anti-inflammatory analgesics(aspirin, piroxicam) and CNS depressants(diphenylhydantoin). 5. Clinical manifestations according to possible causative drugs were as follows; exanthematous eruptions by antibiotics, antipyretics/analgesics, herbs, CNS depressants, propylthiouracil and captopril; urticaria by antibiotics and herbs; fixed drug eruption by sulfonamide, antipyretics/analgesics and phenobarbital; acneiform eruptions by diphenylhydantoin and isoniazid; Stevens-Johnson syndrome by ampicillin, sulfonamide, aspirin and piroxicam, erythema nodosum by sulfonamide, and lichenoid drug eruptions by propylthiouracil. 6. Positivity to patch and prick tests was shown in 2 of the 18 patients and in 1 of 18 patients, respectively. CONCLUSIONS: The most frequent clinical feature of the drug eruptions were exanthematous in nature and the most common causative drugs were antibiotics, as suspected. To search for the causative drug of the drug eruption, the only usual methods of patch and prick tests were not sufficient in our study.

BACKGROUND: Generalized sterile pustular eruption with fever which occurs in generalized pustular psoriasis (GPP) and acute generalized exanthematous pustulosis(AGEP) present a diagnostic and therapeutic problems. In Korea, there are a few studies of clinical and histopathologic reviews of these diseases, but long term follow-up and comparative clinicopathologic studies of these two diseases are not available. OBJECTIVE: This study attempts to identify the differences of these two diseases in the aspects of clinical, laboratory, and histopathologic findings. METHODS: We evaluated the clinical features, laboratory and histopathologic findings in 41 patients with generalized pustular eruption who had visited Pusan National University hospital during the past 20 years and reviewed the literature. RESULTS: 1. The ratio of patients with GPP(n=32) to ones with AGEP(n=9) was 3.6:1. 2. The mean age at diagnosis was 32.9(male) and 28.9(female) years in GPP, and 10.3 years(male) and 62.8 years(female) in AGEP. 3. The number of patients of GPP with previous personal history of psoriasis vulgaris were 15/32(46.9%) and the number of ones with previous family history of psoriasis vulgaris were 2/32(6.3%). 4. There was no patient of AGEP with personal or familial history of psoriasis. 5. The number of patients with recent drug intake history were 4/32(12.9%) in GPP and 9/9(100%) in AGEP. And common drugs suspected to cause AGEP were antibiotics(4 cases) and analgesics(3 cases). 6. Associated systemic symptoms were fever(37.5%), arthralgia(18.8%), and itching(62.5%) in GPP, whereas 66.7%, 33.3%, and 55.6%, respectively in AGEP. 7. The mean duration of pustules was 32.9 days in GPP and 7.2 days in AGEP. 8. Reccurences of generalized pustular eruption were 46.9% in GPP and 0% in AGEP. 9. Laboratory findings revealed leukocytosis(34.4%), elevated erythrocyte sedimentation rate(28.1%), hypoalbuminamia(25.0%), and eosinophilia(6.3%) in GPP, whereas 77.8%, 55.6%, 33.3%, and 71.4%, respectively in AGEP. 10. GPP and AGEP are diseases sharing similar clinical features, but these two diseases show distinctive clinical, laboratory, and histologic features. We suggest that it is important to be aware of these distinctions for avoidance of unnecessary aggressive therapy indicated for GPP.

Color Doppler echocardiographic examination was performed to detect and evaluate semiquantitatively the severity of mitral regurgitation in 38 patients who underwent left ventriculography. The sensitivity and specificity of the technique in the detection of mitral regurgitation was 84% and 100% as compared with left ventriculography.Mitral regurgitation in the false negative cases was mostly mild. On the bases of the farthest distance reached by the regurgitation flow signal from the mitral value orifice, the severity of regurgitation was graded on a four point scale and these results were compared with those of angiography. A significant correlation(r=0.87) was found between Doppler imaging and angiography in the evaluation of the severity of mitral regurgitation.Also results was obtained for the evaluation based on the area covered by the regurgitant signals in the left atrial cavity & the regurgitant jet area(RJA) experssed as a percentage of the left atrial are(LLA) obtained in the same plane(RJA/LLA%). In conclusion, Color Doppler echocardiography is a useful noninvasvive thechique that is not only sensitive and specific in the identification of mitral regurgitation but also provides accurate estimation og its severity.

OBJECTIVE: There have been no clinical studies regarding the epidemiology and treatment outcome for unruptured intracranial aneurysm (UIA) in South Korea yet. Thus, The Korean Society of Cerebrovascular Surgery (KSCVS) decided to evaluate the clinical and epidemiological characteristics, and outcome of the treatment of UIA in 2006, using the nationwide multicenter survey in South Korea. METHODS: A total of 1,696 cases were enrolled retrospectively over one year at 48 hospitals. The following data were obtained from all patients : age, sex, presence of symptoms, location and size of the aneurysm, treatment modality, presence of risk factors for stroke, and the postoperative 30-day morbidity and mortality. RESULTS: The demographic data showed female predominance and peak age of seventh and sixth decades. Supraclinoid internal carotid artery was the most common site of aneurysms with a mean size of 5.6 mm. Eight-hundred-forty-six patients (49.9%) were treated with clipping, 824 (48.6%) with coiling, and 26 with combined method. The choice of the treatment modalities was related to hospital (p = 0.000), age (p = 0.000), presence of symptom (p = 0.003), and location of aneurysm (p = 0.000). The overall 30-day morbidity and mortality were 7.4% and 0.3%, respectively. The 30-day mortality was 0.4% for clipping and 0.2% for coiling, and morbidity was 8.4% for clipping and 6.3% for coiling. Age (p = 0.010), presence of symptoms (p = 0.034), size (p = 0.000) of aneurysm, and diabetes mellitus (p = 0.000) were significant prognostic factors, while treatment modality was not. CONCLUSION: This first nation-wide multicenter survey on UIAs demonstrates the epidemiological and clinical characteristics, outcome and the prognostic factors of the treatment of UIAs in South Korea. The 30-day postoperative outcome for UIAs seems to be reasonable morbidity and mortality in South Korea.

BACKGROUND: Accurate quantitative testing of HBV DNA is very important for choosing antiviral treatment targets and evaluating treatment response in chronic HBV patients. We evaluated the performance of LG AdvanSure HBV Real-Time QPCR kit (LG) utilizing real-time quantitative PCR. METHODS: The LG kit was conducted for 201 chronic hepatitis patients undergoing treatment at the Korea University Ansan hospital and 48 normal control volunteers. The precision, limit of detection, sensitivity, and specificity of LG Kit were evaluated. Correlation analysis was done with Abbott Real Time HBV kit (Abbott) and the Cobas Amplicor HBV Monitor kit (Cobas) and the concordances rate of the three methods were calculated. RESULTS: The LG assay showed linear range of detection from 10(2) to 10(6) and coefficient of variation (CV) was 1.10~0.52% at > or =1,000 IU/mL and 1.19% at 100 IU/mL. The coefficient of determination for precision analysis was 0.997. The limit of detection for detection of 95% of positive samples was 9.71 IU/mL (54.4 copies/mL). In 201 clinical samples, the log HBV DNA/ml showed good correlation between Roche vs Abott, Roche vs LG and Abott vs LG, respectively (n=105, 108, 133, r2=0.91, 0.89, 0.94, P<0.0001). The overall concordance rate of three methods were 79.1% (159/201), 82.1% (165/201), and 85.1% (171/201), respectively, showing no stastically significant difference (P>0.05). CONCLUSION: LG AdvanSure HBV Real-Time QPCR kit showed outstanding precision, linearity, limit of detection, good correlation with previous methods, and is a valuable tool in treatment monitoring of chronic HBV infections.

BACKGROUND: The expression and secretion of ABH antigens in epithelial cells of glands are controlled by secretor type alpha (1,2)fucosyltrasnferase activity and the human secretor alpha (1,2)fucosyltransferase gene (Sec2) determines the ABH secretor status and influences the Lewis phenotype of an individual. Homozygosity of the mutation for this allele is responsible for the nonsecretor phenotype in nonsecretor individual. The aim of this study was to investigate the status and the distribution of the Sec2 genotype in the Korean population. METHODS: In order to explore the secretory genotypes of the Korean population, the 158 specimens were analyzed by the PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) method designed for the detection of the A385T, the C357T and the G428A mutations of Se alleles. RESULTS: The frequencies of Se1, Se2 and sej among 316 alleles examined in a random sample of 158 Korean individuals were 11.1%, 40.5% and 48.4%. The frequencies of Se1/Se1, Se1/Se2, Se2/Se2, Se1/sej, Se2/sej and sej/sej among 158 genotypes were 3.2%, 3.2%, 20.3%, 12.7%, 37.3% and 23.4%. The G428A nonsense mutation discovered in the Sec2 gene of nonsecretors in Caucasian was not found in any of 158 Korean population. CONCLUSIONS: The distribution of the genotypes of the Sec2 gene in the Korean population showed a rather wide distribution of the sej allele than the Caucasian population and was similar to the Japanese population. PCR-RFLP method can be effectively used for the genotyping of the Sec2 gene.

PURPOSE: The purpose of this study was to understand the principle of percutaneous nephrolithotomy(PNL), toincrease its success rate, and to base the radiologic approach on preoperative interventional tract dilatation. MATERIALS AND METHODS: Twenty-six patients(male, 19, female, 7) with staghorn or pelviocalyceal calculi who hadundergone PNL were included in this study. After percutaneous nephrostomy(PCN) was performed in each patient, thetract was dilated to 30F with Amplatz dilators using coaxial techniques or a 30F, 10cm high-pressure tractdilatation balloon. One day before the calculi were fragmented and removed by PNL, a 30F Amplatz sheath wasinserted under local anesthesia. The time required for tract dilatation, complications, and surgery was analyzed. RESULTS: Percutaneous tract dilatation were successful in all patients, and forceps, a nephrolithotome and anephroscope were successfully introduced into the pelvocalyceal system. The average procedure time was 19.5minutes ; a double J stent was replaced in the pelvocalyceal system of 13 of 26 patients (50%) ; because ofimproper catheter direction or/and bleeding, the Amplatz sheath was replaced in three. After PNL, complicationsinvolving renal hematoma occurred in one patient. This did not affect the patient's prognosis, however. CONCLUSION:Owing to its short procedure time and low complication rate, interventional preoperative tract dilatation forPNL is thought to be an effective technique for patients with staghorn or pelvocalceal calculi.

BACKGROUND: Though many adolescents are suffering from depression in Korea, there have been few studies about the prevalence of it and depressive adolescents are not managed appropriately yet because of ignorance of the society and family. This study was intended to find out college freshmen's prevalence of depression, and the relationship between family function and depression. METHODS: The subjects were college freshmen of one university both in Seoul and Suwon and the study period was from January to February on 1999. Family APGAR was used as a family function index and Beck's Depression Inventory (BDI) was used to measure the degree of depression. Chi square tests and logistic regression were done for analysis using SPSS 8.0/PC program. RESULTS: The prevalence of depression among college freshmen was 1.5%(37 out of 2465) as of BDI score 21 or more. Depression was more common in the families with low Family APGAR score and those in Suwon campus. No significant differences were found in gender, age, blood pressure, blood type, BMI, present illness, number of families, marital status of parents or siblings. Relative risks of depression were 4.5 times for family dysfunction group and 2.6 times for Suwon campus group. CONCLUSION: Depression is not a rare disease among college freshmen. Therefore, family physician as a primary care physician should consider the possibility of depression among adolescence and screen depression using BDI for adolescents in dyfunctional family particularly.
