We analysed forty-six cases of femoral neck fracture treated with internal fixation and followed for more than one year at Korea University Hospital from January 1979 to June 1986 and the following results were obtained. 1. Sex distribution was 23 cases(50%) male and 23 cases(50%) female, and average age was sixty years old (range from 21 to 91 years). 2. The most common cause of injury was slip down(76%). 3. The most common type of fracture was Garden's type III(46%) and Pauwels' type III (67%). 4. In cases of internal fixation, the most commonly used method was closed reduction and multiple pinning under the local aneshtesia(83%). 5. Bony union was established within 5.9 months in average. 6. Among forty six cases, 7 cases(15%) of avascular necrosis, 4 cases(9%) of malunion, and 2 cases(4%) of nonunion was occurred. 7. The clinical results were excellent in twenty cases(43%), good in sixteen cases(35%), fair in seven cases(15%), and poor in three cases(7%) according to Lunceford's assessment.

Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.

It has been studied that a variety of fauna and flora are sensitive biological indicators which reflect the severity of regional pollution of heavy metals, but in the center of part of Taegu city the controversial issue of lead poisoning attributable to the atmosphere which contains an increased concentrations of lead has been raised recently, it is usually hard to find suitable plants or animal in the areas with heavy traffic. Pigeons are ubiquitous in and around Taegu city area, inhabiting even the most densely populated areas with heavy traffic with its small body size, high metabolic turnover, and rather limited mobility, a pigeon, as a biological indicator is expected. This study was conducted to monitor lead pollution in the Taegu and kyongju city in Korea. We measured the lead content of the various tissue of three groups of feral pigeon(Columbia livia) and soil and atmospheric lead concentration. First group was obtained io heavy traffic area in Taegu City, the second group was obtained a park in Taegu city and the third group was obtained light traffic area in kyongju city. The air and soil lead concentration of heavy traffic area in Taegu city was 0.11 microgram/m2, 4.96 microgram/g, that of park in Taegu city was 0.05 microgram/m3, 2.65 microgram/g and that of light traffic area in kyonngju city was 0.03 microgram/m3, 0.01 microgram/g. The lead content of lung, blood, kidney, femur and liver of feral pigeons in heavy traffic area in Taegu city was significantly higher than pigeons obtained in a park in Taegu city and low traffic density area in Kyonfju city(p<0.01). But stomach lead content of three group did not reflect a significant difference. In this study positive correlation was found between atmospheric lead concentrations and the concentration of lead in the pigeon's lung(r=0.5040, p<0.001), blood(r=0.3322, p<0.01), kidney(r=0.4824, p<0.001), femur(r=0.7214, p<0.001) and liverer (r=0.4836, p<0.01). we can also found positive correlation between soil lead concentrations and the concentration of lead in the pigeon's femur(r=0.4850, p<0.001), kidney(r=0.4850, p<0.001) and liver(r=0.4386, p<0.01). In the pigeon`s tissue there were significant correlations between concentration of lead in the blood and kidney(r=0.4818, p<0.001), femur(r= 0.6157, p<0.001) and liver(r=0.3889, p<0.001). In conclusion, at the heavy traffic area in Taegu city, lead concentrations found in the atmosphere and soil are reflected in the lead concentrations of different tissue of urban pigeons. It is suggested that the tissue of pigeons can be good biological indicators of environmental lead pollution.

Atrial fibrillation(AF) diagnosed by fibrillatory waves of atrial activity and an irregular ventricular response on ECG is a common arrhythmia associated with increased cardiovascular morbidity and mor- tality. The incidence of AF increases markedly with advancing age and the presence of congestive heart failure. Most patients with AF can be attributed to organic heart disease such as rheumatic, atherosclerotic and hypertensive heart disease. But there is an increasing awareness of so-called lone AF which has no underlying cardiac or metabolic abnormality. We report a case of paroxysmal AF developed just before the induction of anesthesia in a 73-year-old patient who had no history of cardiovascular disease.

A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance beneficiaries selected by simple random sampling from a Dong (Township) in Taegu. Well-trained surveyors mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease in medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was affordability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.

This study was conducted to measure the lead level in the blood, scalp hair and toenail of the elementary schoolchildren and assess the relationship among those samples. Lead concentration of the blood, scalp hair and toenail was measured for l00(male 50, female 50) fourth grade elementary schoolchildren in Taegu city. The mean lead level in the blood, scalp hair and toenail was 6.00+/-2.44 microgram/dl, 6.28+/-3.54 microgram/dl 6. 68 and 7.33+/-3.18 microgram/g. The mean lead level in the blood of schoolboys was 6.43+/-2.77 microgram/dl and that of schoolgirls was 5.59+/-2.01 microgram/dl. The mean lead level in the scalp hair of schoolboys was 7.66+/-2.97 microgram/dl and that of schoolgirls was 6.88+/-3.54 microgram/g. The mean lead level in the toenail of schoolboys was 8.19+/-3.5 microgram/g and that of schoolgirls was 6.47+/-2.52 microgram/g and their difference was statistically significant. In schoolboys, the correlation coefficient between the lead level in the blood and scalp hair was 0.4909, and the data were fitted best by the regression equation Y=0.5255X+4.2810, where Y and X are scalp hair and blood concentration. In schoolgirls the correlation coefficient between the lead level in the blood and scalp hair was 0.3778, and the data were fitted best by the regression equation Y=0.6655X+2.9632, where Y and X are scalp hair and blood concentration. In schoolboys. the correlation coefficient between the lead level in the blood and in the toenail was 0.5533, and the data were fitted best by the regression equation Y=0.7076X+3.6472, where Y and X are toenail and blood concentration. In schoolgirls the correlation coefficient between the lead level in the blood and in the toenail was 0.2738, and the data were fitted best by the regression equation Y=0.3431X+4.5570 where Y and X are toenail and blood concentration. In schoolboys, the correlation coefficient between the lead level in the scalp hair and in the toenail, in the schoolboys was 0.4148, and the data were fitted best by the regression equation Y=0.4956X+4.3986, where Y and X are toenail and scalp hair concentration. In schoolgirls the correlation coefficient between the lead level in the scalp hair and in the toenail 0.1159, and the data were fitted best by the regression equation Y=0.0825X+5.9214 here Y and X are toenail and scalp hair concentration. Correlation among lead concentration in the blood, scalp hair and toenail of schoolchildren were statistically significant except between scalp hair and toenail in schoolgirls. These finding suggest that blood, scalp hair and toenail can be used substitutive samples between each others.
