Background & objectives : In recent, with the increasing need for medical treatment and changing life styles for personal health care, the need of emergency utilization for the patient seems to be growing. But there are few studies related with emergency room services in the secondary local general hospital. This study was conducted to obtain the basic clinical data of clinical contents of the emergency department utilization at a 250-bed local general hospital for systemic, efficient management of emergency medical services and the better medical planning. Method : This study is an analysis of 11,884 patients in the emergency department at a 250-bed local general hospital in Bucheon city Kyungki province from Mar. 1 1999 to Feb. 28 2000. The patient charts were reviewed and analyzed. Results : The results are follows : 1) Distributions of age and sex in the patients were frequent in 20-29(22.1%), 30-39(18.9%), 40-49(17.5%), under 9(16.6%) and males(60%) were more than females(40%). 2)Distributions of visiting hour in the patients were the most frequent in 8:00(PM)-0:00(AM). 3)Distributions of day of week in the patients were frequent Sunday, Saturday, and Friday in order but admission rates were frequent in Thursday(29.8%), Friday(27.7%), and Wednesday(27.4%). 4)In classifying disease and chief complaints by system, musculoskeletal, digestive, neurologic, and respiratory system were ranked. 5)The results of the patients were classified simple care and medication(75.07%), general ward admission(20.25%), ICU admission(3.89%), and emergency operation(0.29%). 6)The department distributions of the patients were internal medicine, orthopedic surgery, neurosurgery, pediatrics, and general surgery. Conclusion : These findings suggest that emergency room visit in a secondary general hospital was more frequent non-urgent with the sole purpose of a medication or simple care.

Objectives : Entrapment of the suprascapular nerve is frequently overlooked in the differential diagnosis of shoulder pain. Methods : Suprascapular entrapment neuropathy is a well-defined clinical entity and EMG and NCV is used to confirm a diagnosis. But the diagnosis typically not considered until patients develop severe weakness secondary to atrophy of the spinous musculature that the nerve supplies. Results : A narrow suprascapular notch has rarely been reported as a work-related factor of this entrapment neuropathy. Diagnosis of suprascapular entrapment neuropathy is based on the patients' clinical course, neurologic, radiologic, and electrophysiologic findings. One of the most helpful evaluations was anteriorposterior projection with the X-ray tube angled 15-30 degree caudally. The suprascapular entrapment neuropathy is relatively uncommon entity of shoulder discomfort(pain, weakness, and atrophy). Conclusions : If the worker who used his shoulder joint repetitiously having the shoulder pain and muscle weakness, we must rule out the suprascapular entrapment neuropathy. And it is needed to evaluate the motions which cause suprascapular entrapment neuropathy as the ergonomic factor.

This study was to investigate the effect of lead on the selected clinical renal function in female lead workers. The 123 female lead workers from 9 lead industry and 177 females who were not occupationally exposed were examined. Females who had history of renal disease or oral medication were excluded. Blood lead, zinc protoporhphyrin in blood, delta-aminolevuilinic acid and hemoglobin were exaimned as of lead exposure indices and blood urea nitrogen, serum creatinine, serum uric acid and urine protein were examined as of renal function in dices. Mean concentration of lead were 40.7(±13.02)㎍/㎗ for lead workers and 10.7(±3.56)㎍/㎗ for non-lead workers. Differences between lead workers and non-lead workers in blood lead, zinc protoporhphyrin in blood and delta-aminoleuvulinic acid were statistically significant. There were significant differences between lead workers and non-lead workers in blood urea nitrogen, serum creatinine, serum uric acid except urine protein but their mean concentrations were all within normal limits. Serum creatinine and urine protein were not increasing according to the increasing blood lead. when the cut off points of 20㎎/㎗ in blood nitrogen, 1.2㎎/㎗ in serum creatine, 7.0㎎/㎗ in serum uric acid, 8.0㎎/㎗ in urine protein and 40㎍/㎗ in blood lead, 100㎍/㎗ in zinc-protoporhphyrin in blood, 7.0㎎/1 in delta-aminoleuvulinic acid were accepted, comparison between frequencies of blood urea nitrogen, serum creatine, serum uric acid, urine protein by the level of blood lead, zinc-protoporhphyrin in blood and delta-aminoleuvulinc acid respectively was not staistically different. There were no dose-response relationships in risk ratios by dose-response relationships in risk ratios by the level of blood lead and zinc-protoporphyrin in blood respectively. In summary, there were no significant effect of lead on the selected clinical renal function among the female lead workers at level of blood lead 40㎍/㎗ that is the permissible level of lead poisoning in Korea.
