Thirty cases of peripheral nerve injury were selected and analysed by means of electromyographic studies at Severance Hospital, Yonsei University, from January 1972 to August 1972. 1. The sex ratio was 17:13 (male: female). The peak incidence occurred in the twenty to thirty year age group. Involved side: right side 18 cases: left side 12 cases. 2. Nerve involved: peroneal nerve (15 cases), tibial nerve (2 cases), median nerve (7 cases), ulnar nerve (4 cases) and radial nerve (2 case). 3. Mode of nerve injuries 1) Peroneal nerve: Nerve compression, variable (10 cases) Tibia & fibular fracture complication (4 cases) Stab wound, fibular neck region (1 case) 2) Tibial nerve: Injection neuritis, buttock (2 cases) 3) Median nerve: Cut glass laceration, wrist region (3 cases) Carpal tunnel syndrome (3 cases) Undetermined mode (1 case) 4) Ulnar nerve: Cut glass laceration, wrst region (2 cases) Forearm bones fracture complication (1 case) Supracondylar fracture (cubitus valgus) (1 case) 5) Radial nerve: Cut glass laceration, wrist region (1 case) Crushing injury, elbow region (1 case) 4. Among the 15 cases of peroneal nerve injury, there were 10 cases of partial denervation and 5 cases of complete denervation. 5. The mode of injury in 10 cases of partial denervation was nerve compression from the following causes: lithotomy posture during forceps delivery (1 case), external rotation of legs during recovery state after surgery (3 cases), abnormal posture during coma state after CO intoxication (2 cases), tight long leg cast (3 cases), and direct trauma while descending stairs (1 case). 6. In all 10 cases of partial denervation of the peroneal nerve, decreased motor nerve conduction velocities, diminished amplitude and prolonged latencies were observed. 7. In partial denervation of the peroneal nerve, the earliest that reinnervation was observed was within 3 weeks in 3 out of 10 cases. 8. Spontaneous fibrillation was observed 3weeks after injury in all cases except one in which it was observed only 7 days after peroneal nerve injury. 9, The earliest appearance of positive sharp waves among all peroneal nerve injuries was observed 2 weeks after injury. 10. The initial appearance of nascent potentials (polyphasic potentials) in peroneal nerve injuries was observed 3 weeks after injury (1 case), 5 weeks after injury (1 case), and 5 months after injury (1 case). They are all partial denervation cases due to nerve compression. 11. Ten cases of partial denervation of the peroneal nerve were treated with electrical stimulation and drop foot board with good recovery. Five cases of complete denervation of the peroneal nerve were treated with neurorrhaphy (1 case) and short leg bracing (4 cases). 12. The initial appearance, of polyphasic potentials was observed 5 months after injury in one case out of 3 cases of median nerve injury. 13. Three cases of median nerve injury were classified as carpal tunnel syndrome and occurred in women only. Observations included absence of sensory nerve action potentials below the lesion, delayed distal latency at wrist and normal motor nerve conduction velocity. They were treated by division of the deep transverse carpal ligament with good result. 14. The initial appearance of nascent potentials was observed 7 months after injury in one case among 3 cases of ulnar nerve injury. 15. In two cases each of radial and tibial nerve injury, no reinnervation pattern was observed until the six month follow-up study after injury. At that time no muscle contraction could be seen or palpated clinically. 16. We observed normal motor unit potentials in the muscles in the follow-up studies even though muscle contraction could not be seen or palpated clinically. 17. Electromyographic examination at selected intervals made accurate diagnosis and prognosis possible and aided in evaluating the course of nerve regeneration, which permictted the choice of appropriate treatment.

PURPOSE: To identify the incidence of cutaneous injury in clinical nurses. METHOD: From Feb.1 to 28, 2005, 276 clinical nurses were surveyed by questionnaire. RESULTS: 1. Of the nurses, 53.6% had at least one incidence of cutaneous injury, and the mean number of injuries was 1.34. A higher incidence rate for cutaneous injury was found in nurses who were under the age of 25, unmarried and who had less than 3 years career experience. 2. The major causes of injury were syringe needles at 65.0%, and medical instrument were next followed by sharp objects or blades. The injuries occurred when the nurses were rearranging equipment after care (25.2%), taking blood samples (22.8%), separating syringes and needles (17.1%), during surgical operations (14.2%), and distribution of medications, treatments and recapping of needles (5.7% each). The hands were the most common body parts injured, and the most prevalent pathogens contaminating the instruments causing the injury were HBV, syphilis, HCV and HIV in that order. 3. Of the injured nurses, 77.9% did not report the accident and 25.8% did not receive any treatment because there were no pathogens, it was a bother or there was difficulty reporting the incident. CONCLUSION: To reduce cutaneous injuries, intensive training and supervision may be needed for those of nurses under the age of 25, unmarried and with less than 3 years career experience.

OBJECTIVEs: Cytogenetic investigations were carried out on 770 women with primary (n=560) and secondary amenorrhea (n=210) to determine the frequency of chromosomal or genetic causes of amenorrhea. MATERIALS AND METHODS: In 770 women with primary amenorrhea (n=560) and secondary amenorrhea (n=210), chromosomal analysis were performed. RESULTS: 1) The most prevalent age group is 16-20 years of age group with primary amenorrhea and 26-30 years of age group with secondary amenorrhea. 2) Out of 560 cases of primary amenorrhea, 343 cases (61.3%) had the normal chromosome constitution and 217 cases (38.7%) had the abnormal chromosome constitution including 46,XY. 3) In 217 cases of abnormal chromosome of primary amenorrhea, 57 cases (26.3%) had 45,X and 34 cases (15.8%) had the 46,XY, 24 cases (11.0%) had 45,X/46,X,i (Xq), 23 cases (10.6%) had 45,X/46,X,+mar and 14 cases (6.6%) had 45,X/46,XY. 4) Out of 210 cases of secondary amenorrhea, 181 cases (86.2%) had the normal chromosome constitution and 29 cases (13.8%) had 45,X/46,XX. CONCLUSION: High percentage of chromosomal abnormalities was diagnosed in primary amenorrhea and most of them were sex chromosome anomalies. In secondary amenorrhea, the prevalence was lower than primary amenorrhea, so a preselection of patients with secondary amenorrhea for cytogenetic investigations seems to be necessary.

PURPOSE: To provide basic data for strategy of substance abuse through the investigation of the status of substance abuse and knowledge and attitude about drugs in the elementary students. METHOD: Subjects were 565 6th grade of elementary students. Data were collected from June to July 2001 by using structured questionnaire. RESULT: 1) Among the students of respondents, 10.2% of them had the experience in smoking, 26.7% and 08% of them in drinking and inhalants, respectively. 2) The degree of students' knowledge about substance was 20.9 points on average with the highest score being 30. Students' knowledge about substances, smoking came on top, next came drinking and inhalants followed them. There were no significant differences in the knowledge of substances by general and drug related characteristics of the students. 3) The students' attitude about substances was negative with 30 points on average with the highest score being 108. As for the attitude about substances, they revealed the most generous in drinking next in smoking and inhalants. Those of boys, bored in school life and experienced in substance abuse were significantly generous in the attitude about substances. 4) There was a significant weak inverse relationship between the student's knowledge and attitude about substances (r=-0.13). As for the relationship between the student's knowledge and attitude about substances, the strongest relationship was shown in inhalants (r=-0.18) next in drinking (r=-0.16) and smoking (r=-0.06). CONCLUSION: The results of the finding suggest that the developing of programs in substance abuse for the elementary students are needed not only for the prevention but also for the cessation.

A randomized comparison group pretest-posttest experimental design was used to quantitatively determine the effects of environmental control measures on patients with allergic rhinitis. Environmental controls included wrapping the mattress with a vinyl cover, washing the top bedding cover with 55 degrees C hot water every two weeks, removal of soft furniture, and wet cleaning of the bedroom floor every day. Thirty subjects were randomly assigned to experimental and control groups. The amount of house dust mites in dust samples collected from the bedroom floor, bedding and mattress, as well as the nasal symptoms of patients, were measured twice at one-month intervals. A significant decrease in house dust mites in dust samples and relief in patients' nasal symptoms were observed in the experimental group who had environmental controls.

This study was conducted to investigate distribution of the house dust mites in the bedroom of allergic rhinitis patients in Pusan. From July to December 1995, 51 dust samples were drawn from the bedroom of the patients by using electronic vaccum cleaner. House dust mites were isolated from 50mg dust by applying the modified wet sieving method. The results were as follows: 1 Out of a total 49 dust samples(96.1%) were isolated house mites. 2 Total 977 mites were collected and identified the most prevalent house mites was Pyroglypidae mite with 92.2%. Among them D.pteronyssinus was predominant species. 3 In 1gm of the house dust, 100-499 mites were found in 17 samples(33.3%), more then 500 mites in 12 samples (23.6%). 4 The density of Pyoglypidae mite was close associated with the month. 5 The density of house dust mite was not affected by the type of house, region and the relative humidity of the bed room

PURPOSE: To investigate the level of depression and self management behavior in patients with diabetes. METHOD: From May to August 2004, 124 diabetic patients 18 years or older were surveyed using the Korean version of the BDI, the self-management scale by Toobert(2000) and hospital lab data for HbAl, FBS and Blood Sugar-2hr. RESULTS: 1. Mean score on the BDI for the patients was 10.85 points. The score on the BDI was significantly higher in hyperglycemic patients than in normoglycemic patients. 2. The level of self management for the past week showed care on an average of 4.2 days. According to level of depression, patients in the normal group and patients in the mild group had significantly higher levels of self management than those in the moderate group. 3. According to level of depression, patients in the normal group had significantly lower levels of blood glucose than those in the moderate group, and for HbAlc and FBS those in the mild group had lower levels compared to those in the moderate group. 4. The factors significantly associated with level of self management were depression (25.66%) and duration of illness. CONCLUSION: Programs should be developed to combat depression in patients with diabetes in order to increase compliance through self care management and thus increase of blood glucose levels.
