The hepatitis C vims(HCV) is now known to be the chief cause of transfusion-associated non-A, non-B hepatitis. The ultimate goal of blood donor screening for anti-HCV antibodies is the specific exclusion of vital carriers from the blood donor population. Recently, a third generation anti-HCV screening(Green Cross Center Innotest HCV 3.0 Genedia HCV 3.0 ) and immunoblot assay, Inno-Lia HCV Ab III (Innogenetics) using antigens derived from the core and different nonstructural regions(NS3, NS4 and Ns5) of the HCV viral genome were developed. To evaluate the usefulness of these assays, anti-HCV reaction patterns of the Inno-Lia HCV Ab III or presence of HCV-RNA detected by reverse transcriptase-polymerase chain reaction(RT-PCR) were examined samples in which were repeatedly positive or discrepant with Abbott EIA-2, Innotest HCV 3.0 Genedia HCV 3.0 The reaction intensity of Innotest HCV 3.0 Genedia HCV 3.0 was higher than that of Abbott EIA-2. The sensitivity and specificity of Innotest HCV 3.0 and Genedia HCV 3.0 were 92.9% and 86.8%, respectively, and the positive and negative predictive values were 72.2% and 97.1%. both. The sensitivity and specificity of Abbott EIA-2 were 100% and 78.9%, respectively, and the positive and negative predictive values were 63.6% and 100%, respectively. We concluded that the new third generation HCV EIA reagents can decrease a false positivity of second generation EIA reagents and correlate well with detection of HCV-RNA by RT-PCR.

BCG osteomyelitis occurs in the infants and children as complication of BCG vaccination and its occurrence is very rare. It involves the metaphysis of the long bone and its development is chiefly hematogenous spread and direct inoculation. Radiologic feature shows well demarcated, eccentrically located destruction in the metaphysis of the long bone and soft tissue swelling about the lesion but periosteal reaction was absent initially. We experienced a case of BCG osteomyelitis which occurs in the left proximal humerus in 3 month after BCG vaccination.

Supracondylar fracture of the humerus is the most common fracture of the elbow in children For period of 4 years from Jan. 1980 to Dec. 1983, 54 children with dispaced supracondylar fracture of the humerus were classified by direction of displacement of distal fragment and treated by immediate closed reduction after lateral skeletal traction. 32 cases of these were followed up for more than 6 months. The results were obtained as follows.: 1) The most common incidence (79.6%) was 5 to 12 years of age and male and female ratio was 2.4 : l. The left humerus was involved in 35 cases (64.8%). 2) Of all fracture, extension type was 96.3% and flexion type 3.7%. 3) Under the exact anteroposteier and lateral views, fractures were classified by displaced direction of distal fragment. Immediate closed reduction was done by using thick and strong periosteal hinge after lateral skeletal traction. The more accurate anatomical reduction was obtained by maintenance of reduction state and further correction during lateral skeletal traction, and complications such as VIC, loss of reduction were lessened probably. 4) For follow up study of 32 cases, final result were analized according to Mitchells classification. Excellent results were obtained 23 cases (71.9%) Good results were 8 cases (25.0%) Unsatisfactory result was 1 case (3.1 %) 5) In 2 cases of treatment failure, the brachialis muscle was buttonholed by metaphyseal spike of the proximal fragment. 6) During lateral skeletal traction, superficial infection was developed through pin tract in 4 cases. These were treated by the administration of antibiotics and there were no complication such as osteomyelitis.

A statistical study was done on arrhythmia of the aged who were older than 60 during the period 1963~1972 at Seoul national University Hospital. This study included 6,511 patients among 40,000 total patients. The results were as follows. 1) Arrhythmias were observed among 3,058 patients(46.97%). Sinus irregularitis were the most frequent arrhythmia. 2) Except sinus irregularities premature beat (38.3%), atrial fibrillation (16.1%), bundle branch block (10.5%), atriovenricular block (10.5%), atrioventricular escape beat (5.1%), atrioventricular junctional rhythm (4.9%), wandering pacemaker(4.0%) and paroxysmal tachycardia(2.5%) were frequent arrhythmias. 3) Cardiovascular disease was major underlying disease. In cardiovascular disease group, the incidence of arrhythmia was 51.15% which was three times as high as non-cardiovascular and normal group. 4) Most arrhythmias were more frequently observed among the aged except bundle branch block and ventricular paroxysmal tachycardia. 5) The incidence of arrhythmia was similar among the aged except pre-excitation syndrome which was predisposed to woman. 6) Arrhythmia was most frequently observed in coronary heart disease. 7) Among sinus irregularities, simus bradycardia was more frequent in the aged. 8) There were no significant differences in frequency of arrhythmia between non-cardiovascular disease group patients and normal group.

OBJECTIVES: Recent studies have focused on characteristics of adolescents who use internet addictively. Due to many ambiguities in the definitions of internet addiction, it is hard to find a tool for diagnosing internet addiction. In this study, we attempt to identify the temperamental characteristics of adolescents who have addictive internet using patterns by administering a newly developed internet addiction scale based on a psychometric technique and temperament and character inventory (TCI) based on Cloninger's psychobiological model. METHODS: Participants were 566 high school students. 478 students were recruited from high schools, and 88 were selected from internet cafes. We applied the internet addiction scale and TCI. All the students were divided into 3 groups (high risk user group, potential risk user group and normal user group) according to the results of the internet addiction scale. TCI scores were compared and analyzed according to the participants' characteristics. RESULTS: There were significant differences in the distribution of internet user group according to gender. Boys had higher percentage of high risk and potential risk users than girls. When each TCI score was compared according to gender, girls showed significantly higher harm avoidance, reward dependence, cooperativeness scale scores and lower persistence, self-transcendence scale scores than boys. TCI scores were compared among the internet addiction risk user groups. Risky internet users showed lower scores in reward dependence, self-directness and cooperativeness dimensions than normal internet users. CONCLUSION: There was a gender difference in internet addiction risk in this study. These results suggest that adolescents who use internet addictively also have higher tendency of problematic social and interpersonal relationship. These tendencies need to be considered as one of the important aspects of internet addiction. This study shows that assessment of temperament and character in adolescents who have problems related to the internet may be needed for understanding their addiction behaviors and underlying psychopathologies.

Objective: Commonly, brain temperature is estimated from measurements of body temperature. However, temperature difference between brain and body is still controversy.The objective of this study is to know temperature gradient between the brain and axilla according to body temperature in the patient with brain injury. Methods: A total of 135 patients who had undergone cranial operation and had the thermal diffusion flow meter (TDF) insert were included in this analysis. The brain and axilla temperatures were measured simultaneously every 2 hours with TDF (2 kinds of devices:SABER 2000 and Hemedex) and a mercury thermometer. Saved data were divided into 3 groups according to axillary temperature. Three groups are hypothermia group (less than 36.4°C), normothermia group (between 36.5°C and 37.5°C), and hyperthermia group (more than 37.6°C). Results: The temperature difference between brain temperature and axillary temperature was 0.93±0.50°C in all data pairs, whereas it was 1.28±0.56°C in hypothermia, 0.87±0.43°C in normothermia, and 0.71±0.41°C in hyperthermia. The temperature difference was statistically significant between the hypothermia and normothermia groups (p=0.000), but not between the normothermia and hyperthermia group (p=0.201). Conclusion This study show that brain temperature is significantly higher than the axillary temperature and hypothermia therapy is associated with large brain-axilla temperature gradients. If you do not have a special brain temperature measuring device, the results of this study will help predict brain temperature by measuring axillary temperature.
