Nine strains (6%) were confirmed as resistant (MIC=20ug/ml) to methicillin (MT) among 150 isolates of staphylococcus aureus. These MT-resistant staphylococcus aureus (MRSA) strains were also turned out to be more less resistant to other antibiotics tested, such as penicillin, chloramphenicol, tetracycline, and gentamicin except for cephaloridine. It was noteworthy, however, that strain MRSA 5 showed a relatively susceptible attitude toward most of the antibiotics tested, while being extremely resistant to MT only. Salt (NaC1) containing (5–3%) media did not have any significant effect on the degree of MT-resistance of MRSA strains. There was, however, such a tendency as that by the addition of salt the degree of MT-resistance was lowered in the highly MT-resistant strains while enhanced in MT-susceptible ones. It was confirmed that penicillinase did not have any effect on the MT-resistance while most of the penicillin- resistant strains produced the enzyme.

Trichinellosis is a parasitic zoonosis of public health importance. It is caused by Trichinella spiralis which has a wide host range including humans. In the present communication, the ELISA technique was employed on a total of 803 blood samples from 7 selected pig breeding farms in 1996 for diagnosis and surveillance of trichinellosis. Out of the entire 803 samples, nine were found to be suspected while one was positive by ELISA. But western blot analyses employed for further confirmation have shown that all of 10 samples did not react to larval excretory-secretory product antigens. These results indicate that pig breeding farms included in the present study are free from trichinellosis. However, it does not mean Korea is free from trichinellosis since human trichinellosis has recently been reported. The necessity of continued surveillance for trichinellosis in both pigs and wild animals was discussed.

In clinical practice fractures of the forearm bones are encoutered as frequently as fractures of other bones. As has been pointed out in many articles, however, the surgical anatomy of the forearm evokes problems in dealing with the diaphyseal fractures of the forearm bones not found in the treatment of diaphyseal fractures of other long bones, The authors have experienced 107 cases of diaphyseal fractures of the forearm bones during the fiveyear period from January, 1972 through December, 1976. A comparison has been made between the two groups one treated by conservative method and the other by open reduction and internal fixation. The results are as follows: 1. The time required for the healing of the fractures was shorter in the conservatively treated group. 2. Restoration of function was more satisfactory in the surgically treated group. 3. Rotational and angulatory deformities were less in the surgically treated group. 4. Forty-one fractures were internally fixed with compression plates, the union rate of which was 100%.

Injury of the tarsometatarsal joints is known to be very uncommon. Injury was most frequently seen as the result of high energy trauma and appear to be occuring more frequently. Early recognition was imperative, since significant long-term disability can result from inadequate treatment. We have reviewed and clinically anafysed 14 cases of tarsometatarsal Fracture-Dislocation treated at our clinic during the period frrqn March 1980 to March 1985. The following result were obtained. 1. Majority of cause of injury was traffic accidents in 10 cases(71%). 2. According to the Wilsons classification, First stage of supination was most common. 3. Associated injuried was 92%. 4. There was no significant difference between operative treatment and conservative treatment.

OBJECTIVES: The purpose of this study is to investigate the clinical significance of activity of daily living(ADL) and to identify the influencing factors on ADL in elderly patients admitted to the hospital-based acute geriatric care unit. METHODS: We studied a total of 279 patients aged 65 years and older who admitted to the Acute Elderly Care Unit at Seoul National University Bundang Hospital between May, 2004 and April, 2005. Comprehensive geriatric assessment including medical, psychosocial and functional evaluation was performed by the geriatric team. RESULTS: Most of the patients need ADL(62.7%) and IADL(68.8%) assistance. Dependent ADL patients were older (p<0.01), admitted via emergency room(p<0.01), demented(p<0.01), and associated with depression(p<0.01), malnutrition(p<0.01), and stroke(p<0.05) compared to independent ADL group. The length of stay was also significantly increased in dependent ADL group(p<0.01) and six-month mortality rate was higher in dependent ADL group(p<0.01). In correlation analysis, MMSE-KC score(r=0.708, p<0.01), nutritional state(r=0.581, p<0.01), the length of stay(r=-0.433, p<0.01), depression(r=-0.309, p<0.01), the numbers of chronic disease(r=-0.287, p<0.01), age (r=-0.236, p<0.01) showed significant association with ADL. In multivariate analysis, cognitive impairment(OR=5.80), emergent admission(OR=4.33), over the 75 years old age(OR=3.33), malnutrition(OR=2.86), and depression(OR=2.61) were identified as the independent influencing factors on ADL dependency. CONCLUSION: ADL dependency is common in elderly inpatient and significantly associated with poor prognosis. Identifying and controlling the influencing factor on ADL decline may improve the patients' functional status and clinical outcome.

STUDY DESIGN: A retrospective study was designed to evaluate the radiographic diagnostic method to detect any abnormal findings and differentiate stable burst fractures with compression fractures at thoracolumbar spine. OBJECTIVES: To evaluate diagnostic sensitivity of radiographic analysis and confirm the effectiveness of the radiographic diagnostic methods to differentiate stable burst fractures with pure compression fractures. SUMMARY OF BACKGROUND DATA: A data showed that the diagnostic sensitivity using radiographic analysis was 83%. The greater sensitivity was obtained at high posterior superior vertebral angle and PSVA/PIVA > 1.3. MATERIALS AND METHODS: Thirty-one patients with thoracolumbar spine fractures were evaluate to differentiate stable burst fractures with pure compression fractures. All patients were taken X-ray and CT. The PSVA(Posterior superior vertebral angle), PIVA(Posterior inferior vertebral angle), PSVA/PIVA were checked using lateral plain radiographs during follow-up period, and the final data was analysed using radiological & statistical methods. RESULTS: Middle column failure of stable burst fractures was greatly observed at high PSVA(especially >100degree) and high PSVA/PIVA ratio(> 1.3). CONCLUSION: The radiographic analysis using PSVA(Posterior superior vertebral angle), PIVA(Posterior inferior vertebral angle), PSVA/PIVA might be the one of useful methods to differentiate stable burst fractures with pure compression fractures at thoracolumbar spine during follow-up period.

In our hospital we studied the effects of spinal anesthesia with 0.5% isobarie bupivacaine and hyperbaric T-caine in 60 patients undergoing operation of lower abdomen or lower limbs. The following results were obtained. 1) Maximum level of sensory loss were similar in both groups, the time taken to it was significantly faster in the T-caine group but the duration was significantly longer in the bupivacaine group. 2) Onset time of motor blockade was significantly faster in the T-caine group but the duration was significantly longer in the bupivacaine. 3) The fall in blood pressure appeared faster in the T-caine group but no significant value of difference between the two groups. No significant changes were noted in the pulse rates. 4) Post spinal headache developed in 5 patients out of 60 patients (8.3%). With the results, we can assume that 0.5% isobaric bupivacaine is a good local anesthetic agent for spinal anesthesia in operations of the lower abdomen and lower limbs.
