BACKGROUND: For the diagnosis of malaria, examination of blood smear slides by light microscopy is used as standard, and commercial kits detecting malarial antibodies and antigens are available, and molecular methods such as polymerase chain reaction (PCR) are used additionally. But, these diagnostic methods can be performed when clinicians request them, so problems of misdiagnosing the patients who are not suspected malaria may be occurred. METHODS: In 42 Korean patients with malaria, the author analyzed the characteristic signals of malaria using granularity (90 degrees depolarized) versus lobularity (90 degrees polarized) graph of Cell-Dyn 4000 (CD4000) automatic hematologic analyzer. And, the author examined the presence of malaria in 421 random samples by CD4000 and Giemsa stain. RESULTS: The usefulness of CD4000 in diagnosing malaria are as follows, 93.0% sensitivity, 99.3% specificity, 93.0% positive-predictive value, and 99.3% negative-predictive value. CONCLUSION: CD4000 automatic hematology analyzer has high diagnostic sensitivity and specificity in diagnosing malaria. Because complete blood count (CBC) is the routine test for most patients, this method has advantage of time and cost effectiveness and can even detect malaria in unsuspected cases.

OBJECTIVES: This study was conducted to assess the development of posttraumatic stress disorder (PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. METHODS: Forty-seven occupational accident patients with physical injuries were administered BDI, STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). RESULTS: 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident-related factors(<0.05). CONCLUSION: The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only signiticant risk factor for PTSD in occupational accident patients.

BACKGROUND: Breast lesions in children and adolescents are rare and develop mainly in females. The management of breast masses in children and adolescents can be a perplexing problem for pediatricians and surgeons. It is well documented that breast lesions in females under 20 years of age rarely represent malignant disease. However, they frequently are a source of discomfort and anxiety for the patient, particularly when they do not resolve spontaneously. METHODS: To determine the frequency of different breast masses in females under 20 years of age on whom surgery was performed, we carried out a retrospective study of females under 20 years who were admitted to the Department. of Surgery of Soonchunhyang University Hospital for surgery between 1993 and 1995. RESULTS: The mean age was 17.9 years. A total of 44 surgical procedures were performed in 40 patients. The masses ranged in size from 0.8 cm through 7.0 cm. As to the location, the mass was in the right breast of 22 patients (50%) and in the left breast of 22 (50%). The most common location of the mass was in the right upper outer quadrant (13 patients, 29.5%). Of the 44 masses, fine-needle aspiration cytology was performed in 33 masses. Of them, 28 were fibroadenomas, 4 were fibrocystic disease, and 1 was a lipoma. Excisional biopsy was performed on 44 masses. Of them, 33 were fibroadenomas, 4 were fibrocystic disease, 5 was fibroadenoma and fibrocystic disease, 1 was a lipoma, and 1 was a lymphangioma. There were no malignancies. CONCLUSIONS: In female patients under 20 years of age, we suggest that benign breast should be studied for diagnosis, treatment, and histological feature.

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.
