Injuries in the industries has been steadily increasing in this country in recent years. Injuries in the industries intricate in accoriance with the industrial environment, mechanism of injuries and the other factors of employees. In 6 years 201 patients with industrial injuries underwent treatment in the Department of Orthopaedic Surgery of the National Medical Center, and the result of treatment is reported in this paper. 1. 70 cases out of 201 cases were in the age group between 21 to 30 year. 186 cases were male and 15 were female. The incidence is remarkably higher in male. 2. In 80 cases the injuries were caused by machinery with pressor parts. The patients were chiefly manual workers in factories. 3. Of 280 injuries, 148 (62.8%) were upper extremities, 105 (37.5%) were lower extremities and 27 (96%) were trunks. The most common site of injuries was hand. 4 Of 146 injuries with fractures, 94 were treated by manual reduction and cast, and 52 were treated by open reduction. 5. Treatment for open wounds was debridement followed by delayed primary closure and/or skin graft. The primarily closed open wounds by local clinics were observed and treated according to wound condition. 6, 17 cases out of 22 phalangeal bone fractures were treated by manual reduction and splint. 5 cases were treated by K-wire internal fixation, among them 3 cases had to be treated by amputation. 7. Incidence of early camplication was considerably high with 137 sites out of 280 sites and the late complication was 79 sites after treatment of the early complications.

PURPOSE: To evaluate the clinical patterns of corneal erosion induced by contact lens wear and the relations of corneal complications to the duration of contact lens wear and the final wearing. METHODS: We have examined with slit lamp and questionnaire survey, 161 eyes of 105 patients with complication of contact lens wear who visited KyungHee Medical Center from January 2000 to June 2001. RESULTS: Majority of the corneal complication is diffuse punctate type that comprises 58.3%, corneal erosion 14.4%, corneal ulcer 3.1% and so on. Erosional grading and the final wearing time are not proportional to the clinical presentation. Extended-wear soft contact lens was used by 37.1% and RGP lens by 35.2%. Half of the symptoms starts shortly after the lens removal. Corneal ulcer has a significantly higher incidence in the long-duration of wearing group. CONCLUSIONS: The corneal complication is various as corneal erosion, corneal ulcer, and so forth. Consequently, it is quite necessary to give an intensive education to the contact lens wearers, especially in long-duration ones.

We attempted to identify parasite DNA in the biliary stones of humans via PCR and DNA sequencing. Genomic DNA was isolated from each of 15 common bile duct (CBD) stones and 5 gallbladder (GB) stones. The patients who had the CBD stones suffered from cholangitis, and the patients with GB stones showed acute cholecystitis, respectively. The 28S and 18S rDNA genes were amplified successfully from 3 and/or 1 common bile duct stone samples, and then cloned and sequenced. The 28S and 18S rDNA sequences were highly conserved among isolates. Identity of the obtained 28S D1 rDNA with that of Clonorchis sinensis was higher than 97.6%, and identity of the 18S rDNA with that of other Ascarididae was 97.9%. Almost no intra-specific variations were detected in the 28S and 18S rDNA with the exception of a few nucleotide variations, i.e., substitution and deletion. These findings suggest that C. sinensis and Ascaris lumbricoides may be related with the biliary stone formation and development.

Between 1984 and 1996, 8 patients who were suffered from stage g Kienbock's disease underwent interpositional arthroplasty using pronator quadratus pedicled bone. Patients comprised 2 males and 6 females, with an average age of 33 years(range 19-47). Range of motion of the wrist, residual pain, grip strength, and carpal height ratio of the patients were analyzed. The follow-up period was between 1.5 years and 12.5 years(average 5.5 years). The arc of flexion-extension of the wrist was increased from average 74 degrees preoperatively to 96 degrees postoperatively. Among eight patients, five were free of pain and three had intermittent pain during heavy work. None of eight patients had any discomfort in daily work and changed his or her occupation. The grip strength was average 83% of the normal side. Carpal height ratio was average 0.48 preoperatively and was not changed postoperatively. Clinical results, assessed by Lichtman-Evans criteria, showed 4 good and 4 fair. The interpositional arthroplasty using pronator quadratus pedicled bone was considered as a very effective method for the treatment of stage III Kienbock's disease.

PURPOSE: we clinically measured the temperature rise in real time and analyzed the difference of albino rabbit and pigmented rabbit in use of the specially designed thermometer. METHODS: Specially designed thermometer was attached into the subretinal pigment epithealial and choroidal space through the suprachoroidal space in three pigment and three albino rabbits, with diode laser of 810 nm wave length, 3 mm spot size. We examined the retinal temperature according to laser irradiance power at each ten seconds during sixty seconds and the laser power setting was 200 mW, 300 mW, 400 mW in pigmeted rabbit and 300 mW, 600 mW, 800 mW in albino rabbit. We analyzed the results based on the measurements at least three times per each irradiance power. RESULTS: In albino rabbit, the maximal range of retinal temperature change was 1.2 degrees C and 1.7 degrees C in 300 mW and 600 mW, 14.1 degrees C in 800 mW power of 810 nm diode laser irradiance. In pigmented rabbit, the maximal range of retinal temperature change was 12.1 degrees C in 200 mW of laser irradiance power, 16.2 degrees C in 300 mW, 24.3 degrees C in 400 mW during sixty seconds in 810 nm diode laser. CONCLUSIONS: We investigated the ratinal temperature at transpupillary thermotherapy in 810 nm wavelength diode laser on rabbits. The difference of retinal temperature change was in accordance with the amount of chorioretinal melanin pigment. Therefore if the laser power setting used in caucasians would be attempted in orientals, it is the point to be considered during transpupillary thermotherapy.

BACKGROUND: This clinical trial was performed to evaluate the hemodynamic and side effects of enoximone, a newly developed phosphodiesterase inhibitor, in moderately severe congestive heart failure in Korean population and to base the development of long acting oral preparations in the future. METHODS: Principal admission criteria for this trial were a left ventricular ejection fraction of less than 45% by radionuclide ventriculography, NYHA functional class II or III and a documented congestive cardiomyopathy. Exclusion criteria were restrictive cardiomyopathy, valvular heart disease, multisystemic lillness and uncontrolled ventricular tachyarrhythmia. The hemodynamic measurements were made by using the thermodilution Swan-Ganz catheter and radial arterial canulation. Enoximone was administered(continuous infusion) for 24 hours after initial bolus. The hemodynamic parameters to be observed were blood pressure, heart rate, cardiac output, pulmonary capillary wedge pressure, systemic and pulmonary vascular resistance. The clinical reponse, hematology, blood chemistry, and Holter monitoring were checked before and after enoximone trial. RESULTS: The following results are obtained. 1) The included patients were 15 females, 24 males, total 39 patients and mean age of 55.3 years old(28-70 years old). 2) The causes of congestive cardiomyopathy were idiopathic 35(89.9%), hypertensive 3(7.7%), and alcoholic 1(2.6%). 3) The mean ejection fraction measured by radionuclide left ventriculography were 28. 6%. 4) THe cardiac output was significantly increased(50%), and pulmonary capillary wedge pressure(38%), systemic vascular resistance(34%), pulmonary vascular resistance(27%) were significantly decreased during enoximone infusion. 5) NYHA Functional Class was improved by 1 step with enoximone. 6) There were no significant changes in hematology, blood chemistry, and Holter monitoring with enoximone. CONCLUSION: From the above results, the short term intravenous enoximone was very effective in moderately severe congestive heart failure in congestive cardiomyopathy without major adverse effects in Korean.

We experience a case of 34-year-old Turner's syndrome(45, XO) associated with atrial septal defect(secondum type) and mitral valve prolapse who was admitten due to moderate exertional dyspnea. It is well know hat chromosomal abnormality is one of the etiology of congenital heart disease. In case of Turner's syndrome, coarctation of aorta or bocuspid aortic valve is frequently combined, but atrial septal defect simultaneously with mitral valve prolapse is not reported till now in Krea. We report this case with a brief review of the literature.
