In parentage testing DNA profiles are used to link the alleged father with paternity by matching their patterns. The probative value of a match is often calculated by multiplying together the estimated frequencies with which each particular VNTR or STR pattern occurs in a reference population. When this calculating method applies to the motherless case of paternity disputes, a calculation must usually be based on types determined for the child and the alleged father. In such case, the first consideration is to exclude a man from paternity of a child when the man did not have the child's paternal allele at some loci, or if the paternal allele cannot be determined, when the man had neither of the child s alleles. The second is to evaluate the DNA evidence when a man is not excluded by the paternal allele. This work is to provide theories of paternity analysis with three approach methods for the motherless case, and to evaluate their efficiency compared to the trio case when the man tested is not excluded. Consequently, the motherless case offers lower probability exclusion and questionable cumulative paternity index than those of the trio case as being typed with 14 STR loci(CSF1PO, TH01, TPDX, vWA, D5S818, D13S317, D7S820, D16S539, FGA, D21S11, FES/FPS, F13A1, D18S80, D17S5). Since the motherless case in paternity disputes is less efficient for paternity exclusion of the child, the use of genetic maker systems with the higher value of mean exclusion chance(MEC) and exact levels of the relative probability of paternity must be of importance considered in the analysis of such deficiency cases.

BACKGROUND: Cleaning and disinfection of fiberoptic bronchoscope requires careful attention, especially to mycobacterium species because the contamination of mycobacteria could raise confusion on diagnosis. Recently, we detected contamination of Wydex(R) solution used in bronchoscope washer with Mycobacterium chelonae. In this study, we evaluated the mycobactericidal effect of 12 kinds of disinfectants for M. chelonae. METHOD: To evaluate the bactericidal effect of Wydex(R) 2%, Cidex(R) 2.25%, Cidex(R) 3%, Bacteriokiller (BK) disinfectant, Perasafe(R), HICLO-S(R), Lamicine(R), ethanol, Instrusept(R), Virkon(R), Betadine(R), and Vipon(R) against M. chelonae, culture was performed after exposure of two M. chelonae strains (ATCC 35749, the type strain and the strain isolated from contaminated Wydex(R) solution) to each disinfectant solution. The growth of organism was examined for up to 8 weeks. RESULTS: Growth of M. chelonae (reference strain of ATCC 35749 and isolated strain) was observed after a week incubation for Wydex(R) 2%, Cidex(R) (2.25%, 3%) and control. For BK disinfectant and Perasafe(R), they grew after 2-3 weeks, and 3-4 weeks, respectively. For HICLO-S(R) and Lamicine(R), only the contaminated strain grew after two and three weeks, respectively. For ethanol, Virkon(R), Betadine(R), Vipon(R), and Instrusept(R) , growth was not observed from either strain. CONCLUSIONS: On the basis of these results, Instrusept(R), virkon(R), ethanol, Betadine(R), and Vipon(R) were effective for the disinfection of M. chelonae. Especially, Instrusept(R) was thought to be useful as a disinfectant for bronchoscopes because it has advantages including non-corrosiveness, chemical stability, and non-irritativeness. And additional washing with ethanol might be effective. The finding that strain isolated from contaminated bronchoscopes was more resistant to disinfectants than reference strain suggested that the more resistant strains are selected throughout the improper disinfection.

Leber's hereditary optic neuropathy is caused by a single nucleotide change in the mitochondrial deoxynucleic acid(mtDNA) and accounts for 30% of bilateral optic atrophy of unknown etiology. The authors found 11778 mtDNA mutation in 12 patients and evaluated the clinical manifegtations. We confirmed various phenotypes exist in Leber's hereditary optic neuropathy in Korea.

PURPOSE: To evaluate the effects of wearing rigid gas permeable (RGP) contact lenses on the topographic changes in keratoconus. METHODS: Seventy-seven keratoconic eyes that wore multicurve RGP contact lenses and 30 keratoconic eyes that wore no contact lenses were retrospectively analyzed. The mean follow-ups were 22.6 and 20.5 months in the lens-wearing and control groups, respectively. Visual acuity, comfort, daily wearing time, and corneal staining were evaluated for both groups. The changes in topographic indices were compared between the lens-wearing and control groups. RESULTS: Multicurve RGP lens corrected logarithm of the minimum angle of resolution visual acuity of the lens-wearing group significantly improved from -0.016+/-0.065 to -0.032+/-0.10 at follow-up (p=0.05). In the lens-wearing group with advanced keratoconus, the Sim Kmax, Sim Kmin, apical power, astigmatic index, and anterior elevation significantly decreased from 57.68+/-4.26 diopter (D), 50.50+/-2.32 D, 62.79+/-5.11 D, 7.20+/-0.55 D and 67.36+/-16.30 microm to 55.51+/-4.28 D, 49.62+/-3.26 D, 60.31+/-5.41 D, 5.90+/-0.51 D and 60.61+/-16.09 microm, respectively (paired t-test, p<0.05). The irregularity index of 3 mm did not significantly change. Meanwhile, in the control group, the apical power and irregularity index increased from 55.56+/-7.25 D and 3.06+/-1.68 D to 57.11+/-7.75 D and 3.25+/-1.71 D, respectively (paired t-test, p=0.008, p=0.01). CONCLUSIONS: Properly fitted multicurve RGP contact lenses are not likely to contribute to the progression of keratoconus.

BACKGROUND: Abdominal pain is one of the most common complaints in the emergency department and the evaluation presents an extraordinary challenge to the emergency physician's skill. C-reactive protein, an acute phase protein which is increased in the presence of inflammation in various clinical conditions, has been proven useful in assessing disease severity, in monitoring the development of complications, and in evaluating the response to specific treatments. So we tried to determine whether CRP offers an advantage over other clinical or laboratory variables for decision-making in the management of acute abdominal pain in the emergency department. METHOD: Patients who came to a University Hospital ED with acute abdominal pain, between september 1, 1998 and November 30, 1998, were included in this study, Data collection included age, sex, duration of symptom, location of pain, and laboratory dta(white blood cell count, portion of neutrophils, ESR, CRP, amylase). RESULT: This study included 85 patients, 34 of whom were men. The mean age was 36.9+/-19.1 years. CRP might be useful to detect the serious condition, sensitivity 81%, but more useful to differentiate normal condition from serious condition in acute abdominal pain patients, specificity 83%. CONCLUSION: CRP is an useful indicator of decision-making to abdominal patients in the emergency department. Hospitalization or operation is very unlikely when CRP value is normal.

BACKGROUND: Residual pleural thickening is frequently seen following treatment for tuberculous pleurisy, and pleural decortication is performend occasionally in patients with severe residual pleural thickening. However, predictive factors for the development of residual pleural thickening are uncertain at the initial diagnosis of the tuberculous pleurisy. Therefore, the purpose of this study was to identify the associated factors for residual pleural thickening at initial diagnosis. METHODS: We separated 63 patients diagnosed as tuberculous pleurisy into two groups; group 1 consisted of patients without residual pleural thickening and group 2 comprised patients with residual pleural thickening at the end of tuberculous pleurisy treatment. We analyzed the clinical characteristics, radiological findings, pleural biopsy and characteristics of pleural fluid between group 1 and group 2. RESULTS: The study population and clinical symptoms of the two groups were not significantly different and the duration of symptoms before treatment and the peripheral WBC were similar between the two groups. The presence of pulmonary tuberculosis, pleural fluid loculation or the amount of pleural effusion sid not differ significantly between the thwo groups. The incidence of positive AFB staining(group 1 : 8%, group 2 : 38%) and granuloma(group 1 : 30%, group 2 : 62%) on pleural biopsy specimens was significantly higher in group 2 than in group 1. Pleural fluid WBC and differential count, adenosine deaminase level, pH, preotein level or glucose level did not differ between the two groups. However, group 2 had higher LDH levels (1370±208mg/dl) than group 1 (860±71mg/dl, p<0.05). CONCLUSION: In tuberculous pleurisy, patients with residual pleural thickening following treatment demonstrated a higher incidence of posivive AFB staining and granuloma on the pleural biopsy specimens or higher LDH level in the pleural fluid than patients wihtout residual pleural thickening From these results, we speculate that the amonut of tuberculous bacilli and granuloma are probably correlated with residual pleural thickening in the tuberculous pleurisy.

When we intend to do the personal identification using DNA profiles, it will obviously be better to use as much information as possible. The power of identification is increased by using the genetic marker system such as VNTRs or STRs. Although STRs do not have many alleles per locus as VNTRs, these can be compensated by a large number of loci that are potentially usable. However, it will be more efficient to use a morphic loci. Therefore, prior to choose the genetic marker system of STRs for identification, it is essential to consider the statistical parameters of each STR locus, such as obs-H(observed heterozygosity), exp-H(expected heterozygosity), pM(probability of match), DI(discrimination index), PD(power of discrimination), MEC(mean exclusion chance), MEP(mean exclusion paternity), PIC(polymorphic information content) et al. In this article, we described the exact meaning of statistical parameters for the purpose of identification.
