It is generally recognized that the environmental noise of the various working places thought to be the cause of hearing disturbance. This survey was carried out to evaluate the prevalence of noise-induced occupational hearing loss among the weavers of 39 textile industries in Taegu, Korea. For this survey, 432 male workers and 2,023 female workers were examined their hearing acuity by individual pure tone threshold determination test(air conduction), from November, 1972, to January, 1973. Main findings were as follows: 1. The mean of noise intensity of the 54 weaving rooms was, in over all, 95.6+/-4.2dB (A), 95.9+/-4.0dB (B) and 96.2+/-3.9dB (C). 2. The mean hearing threshold levels by service years in the 4,000 Hz were intensively increased from 1st to 3rd year and slightly decreased, than that of 3rd year, from after 3rd to 5th year, after 5th year that increased slightly. 3.The mean hearing threshold levels by frequencies were highest in the 4,000Hz(male:25.0+/-11.3dB, female:22.0+/-10.2dB) and followed by 6,000, 8,000 and 3,000Hz. 4. The mean hearing threshold level of the 6,000Hz(male:17.0dB, female:17.9dB)was higher than that of 4,000Hz(male:16.4dB, female:17.1dB) in the 1st service year. 5. The mean hearing loss of examinees was 16.2+/-8.0dB in male and 15.4+/-7.8dB in female.

The nodular vasculitis described by Montgomery on 1945 and is characterized by relatively chronic, persistent, or recurrent nodular lesions of nontuberculous origin chiefly on the legs. In the differential diagnosis the following must also be considered; erythema induratum, eythema nodosum, Weber-Christian disease, erythema nodosum migrans, recurrent thrombophrebitis and periarteritis nodosa. The authors observed one case of nodular vasculitis caused by sulfa drug. This patient was diagnosed to papulonecrotic tuberculid at first and treated by prednisolone 20 mg, INH 300 mg and streptomycin l.0 gm BIW. By the treatment, the patient, was cured completly within 3 months but visited again because of recurrence after 6 months. Therefore, same medication was given, but did not show improvment and added sulfa drug, Lederkyne. But, unfortunately the skin lesions was aggrevated after sulfa medication. It was suggestive that the cause of aggrevation was sulfa drug and discontinued the sulfa drug. The skin lesions were completely cured after the drug was discontinued.

A case of lymphocytoma cutis, the circumscribed form in 9 year-old girl is reported. This is seldom conclusive without histological examinatien for a wide variety of conditions has to be considered. The circumscribed form usually responds rapidly to radiotherapy, although recurrence is possible and good results from the use of procaine penicillin especially in the disseminated form. In this case, I experienced good results from CO, slush and topical application of 0.25 % fluocortolone 3 times a day without recurrence in 3 months after treatment.

The regeneration of corneal nerve in the graft after penetrating partial homo-keratoplasty had been observed histologically in the experimental rabbits and also the influence of thiamine hydrochloride on nerve regeneration had been studied. Cornea-grafts obtained from the central portion of the cornea by 6 mm trephine were transplanted each other among the rabbits and given 8 sutures in situ under deep sodium pentobarbital anesthesia. Thiamine hydrochloride were given daily does of 5 mg/kg body weight to the grouped rabbits intramuscularly. Enuculeations were done in 5 days, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 18, 20, 22, 24, 26, and 27 weeks after transplantation. Preparations were made with 10-15 micro paraffiserial sections, both of cross and flat, and modified Romanes' silver stain was applied. The results were as follows: 1) Control group: In 5 days after operation, fine nerve fibes were regenerated from the cutted nerve stumps of the host-cornea. After I weeks, nerve plexus were formed in the host-cornea around scar tissue and few fibers penetrated into the scar tissue. After 2 weeks, fine regenerating nerve fibers were found in the transplanted cornea-grafts. Thereafter, numbers and size of the regenerated nerve fibers increased gradually. In 9 weeks after transplantation, nerve innervation in the transplanted cornea-graft was similar to normal cornea. 2) Thiamine hydrochloride treated group: In 5 days after operation, fine regenerating nerve sprouts from the cutted nerves tumps in the host-cornea formed loose nerve plexus and few fibers penetrated into the scar tissue. After 1 week, regenerating nerve fibers were already found in the periphery of the transplanted cornea-grafts. In process of experimental time, nerve fibers in the cornea-grafts more actively regenerated compared with control group. In 7 weeks after homo-corneal transplatation, nerve innervation in the grafts was the same as normal cornea. 3) Thiamine hydrochloride remarkably accelerated nerve regeneration in the transplanted cornea-grafts after penetrating partial homo-keratoplasty.

We report a case of mycosis fungoides in a 37 year-old male patient who had relatively well defined, irregular, erythematous plaques covered with acales on the buttock, lower extremities, anterior chest and back. Histopathological findings showed epidermotropism and Pautrier microabscesses in the epidermis and infiltration of atypical lymphocytes in the upper dermis. Electron microscopic findings showed mycosis cells with convoluted nuclei and prominent nucleolei He had been received PUVA therapy combined with topical and systemic corticosteroid for 4 months. Skin lesions were improved markedly after treatment with total 262 joules/crn2 and then maintained with 14 joules/cm2 in every week.

Single photon emission computed tomographic(SPECT) imaging, performed at oral and maxillofacial surgery department, is valuable in assessing temporomandibular dysfunction, looking for metastases in patients with malignancies, diagnosing facial asymmetry. Conventional planar scintigraphy is limited by two-dimensional representation of three-dimensional structures. The SPECT exam, by sectioning through a distribution of tracer, eliminates the obscuring effects of tracer located outside the plane of interest. In our department, we used this image for four type cases retrospectively. 1. Those patients who have facial asymmetry 2. To find metastases in patients with malignacies 3. In combination with magnetic resonance imagine, to confirm the diagnosis of internal joint derangement 4. To evaluate the viability of grafted bone. Recently, this image is able to be used in those patients whose symptoms etiology cannot be explained by other diagnostic techniques.

Aim. A neurobehavioral test for workers exposed to organic solvents in the workplace can be affected by many factors : age, education, motivation, ethnicity, etc. To apply more suitable neurobehavioral test for Korean workers, we evaluated the validity of several items of computerized and traditional neurobehavioral tests. Methods. We have applied eleven tests : four items of computerized neurobehavioral test(Swedish Performance Evaluation System) including Addition, Symbol-Digit, Digit Span, and Finger tapping speed, and seven items of traditional neurobehavioral test consisting of Addition, Digit-Symbol , Digit Span, Benton visual retention test, Pursuit aiming, Pegboard, and Tapping. These tests were performed on 96 workers exposed to solvents, and 100 reference workers. The concurrent and construct validities were evaluated by group difference, correlation with age, educational level, hippuric acid level, neurotoxic symptom, current exposure level, multitrait-multimethod matrix, factor analysis, and discriminant analysis. Results. Statistically significant differences were observed between the workers exposed to solvents and referents in computerized Symbol-Digit, Finger tapping speed, traditional Digit-Symbol and Pegboard. The computerized Symbol-Digit, traditional Digit-Symbol, Addition, Benton visual retention test, and Pegboard were found to be related to the age. The performance of computerized Symbol-Digit, Addition, and traditional Digit-Symbol were found to be related to the educational level significantly. The computerized Symbol-Digit, Finger tapping speed, and traditional Digit-Symbol were found to be related to hippuric acid, and neurotoxic symptom. The discriminability of Finger tapping speed, and Pegboard was better than the other tests. In discriminant analysis, the model with two variables, the computerized Symbol-Digit and Pegboard, classified almost 70 percent of the workers correctly. Conclusions. These results suggest that the computerized Symbol-Digit, Finger tapping speed, and Pegboard are more satisfactory for our purpose, and the Addition, Tapping, Benton visual retention test, and Pursuit aiming are less valid than other items. These may allow the reasonable selection of core neurobehavioral tests for workers exposed to solvents in Korea.

BACKGROUND: As information technology evolves rapidly computer-based surveillance systems for nosocomial infection have been developed. Well designed computerized system could provide an opportunity for improving, enlarging, and conducting hospital-wide surveillance more efficiently in the situation with limited resources. Recently, we launched a new computerized monitoring system in a hospital where digital medical information system has been operated without paper chart. METHODS: We developed a new surveillance program based on the total Electronic Medical Record (EMR) system. Numerous critical medical information can be easily accessible through this system without further work. This includes major demographic data, essential information from the inpatient medical record, the laboratory information system, and the pharmacy information, Comprehensive Clinical Data Repository (CDR) system was also developed. CDR is potentially very useful to conduct a hospital-wide surveillance by integrating all the available information. RESULTS: This system consists of several programs in the EMR and the CDR environment. In the EMR system, inquiry for patients with fever, case ascertainment and registration of nosocomial infections, inquiry for patients with indwelling devices, microbiological reports, and data on antibiotic prescriptions were included. The CDR has integrated comprehensive inquiries for frequency of major pathogens in clinical isolates and their trends of antibiotic resistance, nosocomial infection rates based on the duration of the devices or hospitalization, and the history of antimicrobial usage based on defined daily dosage. Data obtained from the EMR and the CDR systems could be easily accessed by infectious diseases specialists and healthcare workers of infection control services at any place within the hospital. A new reporting system has been built up to facilitate identification of notifiable diseases among the list of diagnoses on the EMR. In addition, the "Alert" notice was designed to highlight isolation precautions for indicated cases. CONCLUSION: This new computerized surveillance program might be a valuable model to which other hospitals can refer to develop newer version of programs in the future.
