An epidemiological investigation of 878 workers(male 812, female 66) who suffered from low back injury(LBI) in some workplace of Pusan city from January 1 to December 31 in 1992 was carried out to obtain the various informations of the prevention and management in the occupational low back pain(LBP). The results were summarized as follows: 1. The mean age of LBP workers was 39.3±10.4(18-67) in male 48.5±12.6(21-69) in female workers. And the most common age groups were the 4th decade in male and the 6th decade in female workers. 2. In the frequency distribution of LBI according to the kind of industry, manufacturing industry was most frequent, and industry of construction, transport-storage-communication were the next in order. Among manufacturing industry, LBI of metallic products and machinery was the most frequent. 3. The occupational frequency of LBP was technical worker, monotonous worker, driver of automobile, driver of heavy equipment and office worker in order. 4. The cumulative percentage of LBI was 6.9% at the first day of employment and 90.8% until 10 years after employment. 5. The mean working duration from employment to onset of injury was 1081 days(about 2.9 years) and the working duration according to occupation was the shortest in driver of heavy equipment(502 days) and longest in office worker(1982 days). 6. The careless handling of object was the most common cause of LBI, and fall down, slip down, collision and traffic accidents were the next in order. 7. The most common cause of LBI according to occupation was traffic accident in driver of automobile, fall down in driver of heavy equipment and careless handling of object in office worker respectively. 8. The case of localized LBI were 517(58.9%) and the cases of LBI combined with other injuries, such as head, neck, trunk, arm or leg, were 361(41.1%) 9. Lumbar sprain was the most frequent diagnosis of LBI, and Herniated Nucleus Pulposus(HNP) and lumbar fracture were the next in order. 10. In multiple injuries, LBI combined with multiple body injury was the most frequent, and the next was LBI combined with arm and leg, with trunk, with head and with neck in order. 11. LBI combined with multiple body injury was the main injury in fall down, slip down and traffic accident, and lumbar sprain was the main injury in careless handling of object.

To evaluate the degree of competitive exclusion against Salmonella gallinarum(S. gallinarum) of Salmonella enteritidis(S. enteritidis) infected chickens, fifty-six, 4-week old Hyline layer suspected of S. enteritidis infection were challenged with S. gallinarum. All chickens were tested for S. enteritidis isolation using cloacal swabs and serum plate agglutination test using S. enteritidis Ag. before challenge and classified into four groups(SE isolated, SE nonisolated, SE seropositive and SE seronegative). None of the SE isolated and the SE seropositive groups died after challenge and the average weight gains were 245.5g and 254.6g, respectively. But in the SE nonisolated and the SE seronegative groups, mortality was 18.2% and 20.6% and the average weight gains were 150.1g and 111.2g. The incidence of reisolation of S. gallinarum of the SE isolated and the SE seropositive groups were 41.7% and 47.6% from liver, 33.3% and 47.6% from spleen and 8.3% and 14.3% from cecum, respectively, and the SE nonisolated and the SE seronegative group were 63.6% and 64.7% from liver, 84.1% and 88.2% from spleen and 47.7% and 52.9% from cecum. The serological response of the SE isolated and the SE seropositive groups hardly changed from 75.0 and 81.8% before challenge to 75.0 and 85.7% after. But, the other two groups were found to be significantly higher after challenge and increased from 0 and 18.2% to 100%. Consequently, S. enteritidis preinfected chickens were found to be significant different in terms of mortality, weight gain, reisolation of S. gallinarum and serological response compared to noninfected chickens. Moreover, our study shows that S. enteritidis infected chickens appear strong competitive exclusion against the colonization of S. gallinarum.

Primary hyperparathyroidism is a rare endocrine disease in children. It involves bone and joint, urinary tract, gastrointestinal tract and cardiovascular system. The main cause of these involvement is high level of PTH in serum, resulting in hypercalcemia.An 11 years old male patient who had complained of limping gait since last 18 months, showed typical laboratory and radiological findings of primary hyperparathyroidism. At the ultrasonography, computed tomography and radionuclide scanning, a well defined mass(10 X 15mm) was found on the posterior aspect of the right thyroid lobe. The mass was confirmed histologically as adenoma of parathyroid gland. The patient was successfully treated with subtotal parathyroidectomy and temporal administration of calcium and vitamin D.We report this case of primary hyperparathyroidism with brief review of the literatures.

The authors studied anxiety-depression using New Anxiety-Depression Scale (NADS) in the subjects of 2,564 male and 1,252 female college freshmen of Yeungnam University. The authors collected the reports of NADS during the periods from January to February 1987, and applied ANOVA and t-test on anxiety depression scores in order to compare them between various psychosocial factors and sexes. The results are as follows: There was significant difference in the mean average of total scores between male and female students: male students scored 33.41±8.76 and female students scored 35.34±9.02 (P<0.001). The anxiety-depression scores relating to the items of sleep disturbance, apprehension, facial flushing and fatigue were relatively scored higher in both groups. One hundred and thirty nine male students (5.4%) showed seriously higher degree of anxiety-depression scores of 50 or more, while eighty eight female students (7.0%) showed the same scores. There was a strong tendency toward higher anxiety-depression scores in the students who were dissatisfied with their home atmosphere, colleges, departments, familiarity of parents and those who had pessimistic views of self image in the past, presents and future in both groups (P<0.001).

A 43-year-old female patient with a congenital right coronary artery to right atrial fistula presented as congestive heart failure and aortic valve infective endocarditis. The diagnosis was made on the basis of echocardiography, especially TEE and confirmed by tight heart catheterization & aortography. She underwent aortic valve replacement due to severe aortic valve regurgitation with vegetations, fistulectomy and coronary aneurysmorrhaphy. The postoperative course was uneventful. She was treated with antibiotics because of infective endocarditis for 6 weeks. At present she remains well and visits out patient clinic regularly for oral anticoagulation without problem.

The authors studied anxiety-depression using New Anxiety-Depression Scale (NADS), in the subjects of 3,499male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of NADS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety-depression scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total scores between male and female students: male students scored 31.49±6.57 female students scored 33.37±6.84 (p<0.001) The anxiety-depression scores relating to the items of sleep disturbance, apprehension, decreased libido, and fatigue were relatively higher in both groups. Ninety-nine male students (2.8%) showed seriously high degree anxiety-depression scores of 50 or higher, while forty female students (3.0%) showed the same scores. There was a strong tendency toward higher anxiety-depression scores in the students who were dissatisfied with their home atmosphere, colleges, departments and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future in both groups (p<0.001). The students whose maturation locations were below city level, showed higher level of anxiety-depression scores in both groups (p<0.05). NADS and SAS, SDS, and Leeds scale were correlated significantly in 0.64, 0.61, and 0.77 of correlation coefficient.

BACKGROUND/AIMS: Paracentesis is an acceptable therapeutic modality for the symptomatic relief of dyspnea or abdominal fullness due to tense ascites in patients with cirrhosis. Whereas studies about the effects of paracentesis focused on the changes about hemodynamics, electrolytes and renal function in great detail, the effects of paracentesis on the changes about respiratory system have undergone limited investigations which are defined large-volume paracentesis. METHODS: We performed pulmonary function tests with arterial blood gas analysis just before and 24 hr after paracentesis. The paracentesis of average 2,300ml was carried out in ten liver cirrhosis patients with tense ascites who were free from underlying cardiopulmonary impairment. RESULTS: 1. The results of pulmonary function test just before paracentesis were as followings; FVC( functional vital capacity), FEV1(forced expiratory volume in 1 sec), FEF25 75(forced expiratory effort 25% 75%) and TLC(total lung capacity) were decreased as 78%, 79%, 62.3% and 89% of normal control value respectively, whereas RV(residual volume) was not decreased. DLCO(lung diffusion capacity of carbon monoxide)was decreased as 61.6%. 2. The results of pulmona function test 24 hr after paracentesis were as followings,' The symptomatic relief of dyspnea was achieved in all participated ten patients. Among lung volume parameters, FVC and VC were increased significantly(p=0.003, p=0.004). Whereas TLC was increased without statistical significance(p=0.228), and RV and FRC(functional residual capacity) showed no change. FEV1 was increased significantly(p=0.039), but FEF25 75 and the ratio of FEF1/FVC showed no change. DLCO was not increased. PaOy(partial pressure of oxygen in arterial blood) was impr'oved without statistical significance. CONCLUSIONS: These results suggest that the patients of liver cirrhosis with ascites have restrictive ventilatory impairment with additional obstructive ventilatory impairment. After paracentesis, the restrictive ventilatop impairment is improved by the relief of diaphragmatic motion limitation caused by ascites. Also, paracentesis of(not large volume, like 5000ml, but) relatively small volume, of 2000 3000ml can achieve objective improvement of dyspnea due to tense ascites.

Trigeminal neuralgia (TGN) is a relatively well-known disorder with characteristic brief attacks of shooting pain in the facial regions. Atypical signs like constant pain and/or sensory abnormalities can develop as the disease progresses. Some cases begin with atypical signs and later develop all the hallmarks of TGN. The atypical forms of TGN can be misdiagnosed as other pain disorders. We present a patient with facial pain who demonstrated a transformation in signs of glossopharyngeal neuralgia into typical trigeminal neuralgia. A 71 year-old man was referred for sharp episodic pain in his right side of the face and neck. The pain was mainly in the neck, which was worsened especially by swallowing. The condition was initially diagnosed as a glossopharyngenl neuralgia. While controlling the pain conservatively with a sympathetic blockade, the neck pain disappeared suddenly and lower jaw pain triggered by speaking and chewing became prominent, which are the characteristic signs of trigeminal neuralgia.

BACKGROUND/AIMS: Endoscopic sclerotherapy is an accepted treatment for the patients with esogeal variceal bleeding, but endoscopic varicea1 band ligation, introduced by Stiegmann et al in 1986, is a new form of endoscopic treatment method, and may be safer. This study is performed to compare the effectiveness and safety of the two techniques. METHODS: We compared endoscopic sclerotherapy and endoscopic ligation in 10~8 patients who had recently bled from esophageal varices. We assessed the hemostatic efficacy for bleeding varices, the number of sessions of treatments needed to eradicate varices, the incidence of complications, rebleeding rate and survival rate of the patients by two techniques. RESULTS: Active bleeding was well controlled by sclerotherapy in all of six patients, and ligation in all of five patients by the initial treatment. The mean number of treatment sessions required to achieve eradication did not significantly differ between sclerotherapy and ligation(2.4+0.8 vs 1.8+ 1.0 sessions). Complications were less comman in ligation than sclerotherapy; chest discomfort(5.6% vs 29.6%), fever(3,7% vs 16.7%), esophageal ulcer(0% vs 5.6%), esophageal stricture(0% vs 3.7%). The rate of recurrent bleeding was significantly lower in the patients treated with ligation(p<0.05). The overall rate of survival was significantly higher in the patients treated with ligation(p<0.05), The days of hospitalization was significantly shorter in the patients treated with ligation than sclerotherapy(14.8+-7.0 vs 21.0+-9.7 days). CONCLUSIONS: The patients with esophageal variceal bleeding treated with endoscopic ligation have fewer treatment-related complications, lower rates of rebleeding and better survival rates.
