Bromidrosis is a disorder characterized by rancid body odor which influences a patient's social life and mental health. The therapeutic modalities and the mechanism of bromidrosis have been carefully studied, however, there have been few reports about the genetic inheritance of bromidrosis. We investigated the family history of 42 patients who were operated on for bromidrosis and followed up to the third generation in 10 cases. The results were as follows: Results of investigation which were followed up the second generation. The fathers of five patients and the mothers of 11 patients had bromidrosis in 18 male patients. The fathers of six patients and the mothers of 12 patients had bromidrosis in 24 female patients. Thirty-four patient (81.0%) among a total of 42 have a single parent with bromidrosis. Result of investigation which were followed up to the third generation Bromidrosis was occurred in 17 of 42 patients (40.5%) in the second generation, and 18 of 27 patients (66.7%) in the third generation. In one case, a father transmitted bromidrosis to his three sons, and as a result, X-linked inheritance could be ruled out Bromidrosis was not skipped in every generation of all families. We on conclude that bromidrosis is an autosomal dominant inherited disorder.

BACKGROUND/AIMS: There is considerable variance in individual susceptibility to hepato-toxic effects of ethanol as evidenced by the finding that only about 10-20% of alcoholics develop alcoholic liver cirrhosis. The aims of this study were, 1) to get the data on the genetic polymorphisms of three major ethanol-metabolizing enzymes (ADH, CYP2E1, ALDH) in normal Korean adults, and to search for the specific genotypes influencing alcohol drinking behavior by the comparison of allele frequencies between healthy control group and heavy drinker group with or without liver disease, 2) to investigate the influence of the genetic polymorphisms of these enzymes on the susceptibility to alcoholic liver disease by the comparison of allele frequencies between heavy drinker group without liver disease and alcoholic liver cirrhosis group. METHODS: Healthy control group included 53 healthy males in military service without evidence of liver disease or alcoholism. Heavy drinker group without liver cirrhosis included 29 males who had been drinking 80g or more of alcohol daily for more than ten years but did not have any clinical evidence of liver disease. Alcoholic cirrhosis group included 43 male patients who had drunk 80g or more of alcohol daily for more than ten years and had clinical evidences of overt cirrhosis. Subjects with hepatitis B surface antigen or anti-hepatitis C antibody were excluded. Genotypes of the three enzymes were determined by PCR (polymerase chain reaction) and restriction fragment length polymorphism (RFLP) with genomic DNAs extracted from peripheral leukocytes. RESULTS: 1) In healthy Korean males, allele frequency of ADH22, ADH31, CYP2E1 c2 and ALDH22 was 81%, 94%, 30% and 14%, respectively. 2) The absence of ALDH22 or CYP2E1 c2 allele were significant risk factors for being a heavy drinker (odds ratio,' 0.09, 0.42, respectively). 3) Although it was not associated with the polymorphism of each ethanol-metabolizing enzymes, the susceptibility to alcoholic liver cirrhosis was significantly associated with combined genotypes of ADH2(22) & ADH3(1+1)& CYP2E1 B or C. COMCLUSION: Genetic polymorphisms of ethanol-metabolizing enzyrnes are significantly associated with the suseptability to alcoholic liver disease as well as alcohol drinking behavior.

PURPOSE: To describe the magnetic resonance (MR) findings of pigmented villonodular synovitis(PVNS) of the knee, and to evaluate the clinical value of MR in the diagnosis of PVNS. MATERIALS AND METHODS:MR imagings of seven patients with PVNS were studied. The type of lesion, presence of bony erosion, the signal intensity, and the relationship between contrast enhancement and signal intensity on T2-weighted images were analyzed, retrospectively. RESULTS: The lesion was mainly villous in three patients and nodular in four, and bony erosion was seen in one patient. On T2-weighted image, the signal intensity of the villous form was mixed iso- and hypointense in two, hypointense in one, and that of the nodular form was heterogeneous with hypo-, iso-, and hyperintensities. The hypointense portion on T2-weighted image showed poor contrast enhancement, which may suggest hemosiderin deposition or advanced fibrosis. The iso- or hyperintense portion on T2-weighted image showed strong enhancement, which suggest active cellular proliferation. CONCLUSION:MR imaging could be a very useful modality in the diagnosis as well as prediction of histological findings of the PVNS.

A purpose of present study is to provide basic information evaluating the utility of Magnetic Resonance imaging as a biological marker estimating manganese effects to central nervous system among welders, which is conducted by comparing urinary and blood manganese concentrations and signal intensities of brain MR images between exposed group and non-exposed group, evaluating the objectivity of subjective grading estimated by correlations between Pallidal signal intensity index (P. I) and subjective grades among exposed group, and comparing the difference of signal intensities according to presence of neurologic symptoms, signs and exposure variables among the exposed group. The exposed group is composed of 11 welders complaining severe symptoms or showing neurological signs, and the non-exposed group is composed of 5 patients who admitted a hospital. Urinary manganese concentrations and signal intensities in T1-weighted MR images among exposed group were higher than those of the non-exposed group significantly, which exhibits that increased signal intensities in T1-weighted MR image represent the effect of manganese exposure. P. Is among the exposed group revealed relatively high correlations with subjective grades ( gamma =0.63, p=0.037) , which suggests the objectivity of subjective grade. Signal intensity in globus pallidus was a suitable single variable representing the effect of manganese accumulation in C.N.S system appropriately, which was verified as follows ; Increased signal intensities among the exposed group had the highest frequency and intensity in the globus pallidus, and the P.I. had a relatively high correlation coefficient ( gamma 0.62, p=0.044) with total score of subjective grades. Signal intensity with subjective grading in globus pallidus represented very high correlation gamma =0.97, p=0.00) with total score of subjective grades, and had a similar correlation coefficient with many variables. It is hard to argue that signal intensities are markers representing pathologic change in C.N.S system or can be used as a diagnostic tool for manganese intoxication, because signal intensities had no difference between the exposed group and the non-exposed group according to presence of neurological signs.

7.Lamivudine and adefovir combination therapy in lamivudine-resistant HBeAg-positive chronic hepatitis B patients.
Korean Journal of Medicine 2009;77(6):713-715
The introduction of lamivudine (LAM) has opened a new era for the treatment of chronic hepatitis B (CHB). However, the major drawback of LAM, which currently limits its use as first-line therapy, is the high rate of occurrence of drug resistance. In patients with LAM-resistant CHB, recent long-term findings have indicated that adding adefovir (ADV) to ongoing LAM therapy was more beneficial than switching to ADV alone, because the former showed a diminished rate of resistance to ADV with a well-tolerated safety profile. Above all, the most important strategy for CHB treatment must be to use a potent first-line antiviral with high genetic barriers to resistance in order to prevent the development of multidrug resistance.

Epidemiological and statistical observations were made of fire hazards that occurred during the past 18 years, 1948 to 1965. Injury and mortality rates for all ages were computed chronologically. For the years of 1955, 1961 and 1965, all fire accidents were epidemiologically analysed to draw characteristic pattern in relation to the seasonal and 24 hour distribution, causes and sites of accidents etc.. Fire hazards observed herein are the categorys E 916 of the International Classification of Causes of Death, 1955, and includes all accidents caused by fire and explosion of combustible materials. The following conclusion was made: 1. The average umber of annual deaths due to fire was 183 and the number of the injured due to the same cause was 335. The mortality rate per 100,000 population was 0.8 and the ratio of injures per death was 1.8. 2. The casualty rate including both the dead and injured was 5.0 per 100,000 in Seoul, the highest among the provinces and followed by 3.4 in Cheju-Do, 2.1 in Kangwon-Do, 1.7 in Kyunggi-Do accordingly. The other provinces had a range of 0.6 to 1.2. 3. The monthly distribution of fire accidents showed that the winter months, December through February, had more frequent accidents, while the summer season, June through August had less. The 24 hour distribution of accidents showed more cases from 12:00 to 18:00 and less from 4:00 to 10:00 hours. 4. The per cent distribution of causes of accidents showed; 90.0% for careless, 10.0% for arson. The cause of carelessness was further breakdown into; 15.0% for kitchen fire places, 13.8% for fire playing, 9.4% for electrical heating and wires, 8.3% for fuels, 6.3% for matches, 5.2% for ash dumps and the remaining for others. 5. The accidents as classified by place revealed that 56.8% of the total occurred at the common dwelling houses, 11.3 at various industrial workshops, 9.3% at the street shops and the remaining at the miscellaneous places.

With the view point of size, shape and arrangement pattern, authors present normal mediastinal lymph node fromthe analysis of 61 cases of CT scan and multidirectional section of 2 cadavers. The results were as follows: 1.Transverse diameter of the lymph nodes, demonstrated in cadaver section, was 3 to 6mm in upper paratracheal areaand 5 to 14mm in juxta-carinal and AP-window area. Arrangement of the lymph nodes showed tendency of longitudinaldirection in lower paratracheal, and juxtacarinal area, while that of AP window showed tendency of AP direction aslong axis. 2. Mean and the largest size of the lymph nodes demonstrated in CT scan were 3.7mm, 8mm in upperparatracheal area, and 6mm, 12mm in lower paratracheal area, and 7.1mm, 14mm in juxtacarinal area, and 6.3mm and11mm in aorticopulmonary window area. 3. Size fo the lymph nodes in CT scan showed linear increasing tendencyaccording to increasing age(y=0.32, p<0.005). 4. Shape of the lymph nodes in CT scan were mostly round in upperparatracheal area while that of aorticopulmonary window showed higher incidence of oval and elongated shape. 5.Recommended size criterior of abnormal lymph node is 10mm in upper paratracheal are and 15mm in the other area.
