This is to study the incidence of Diabetes and its risk factors in the impaired glucose tolerance group. 1084 subjects who had been examined 3 times for regular check-up in one human dock center under the university hospital were studied between 1986~1993. The results are as follows; Prevalence rate of diabetes was 3.56%, and that of impaired glucose tolerance was 30.90% as of initial examination. The rate of diabetes was increasing with the age where 1.2% at age group 30~39, 3.21% at age group 40~49, 5.84% at age group 50~59, 14.28% at age group 60 and over. And also the rate of impaired glucose tolerance was increasing with the age where 21.29% at age group 30~39, 31.42% at age group 40~49, 38.91% at age group 50~59, 33.33% at age group 60 and over. Of the examinees who were initially examined, total incidence rate of diabetes who developed to obvious diabetes at the 3rd follow-up examination from the initially impaired glucose tolerance group was 4.63% and it was 11.3 times higher than from the normal group (0.41%). After controlling for the effects of both age and obesity, the risk of subsequent diabetes for subjects with impaired glucose tolerance remained significantly higher than for normal subjects (Relative Risk, 10.48). Test for trends for developing to diabetes by the increasing level of fasting blood sugar and 1 hr blood sugar at the initial examination were statistically significant in either normal and impaired glucose tolerance group. To determine the risk factor for developing to diabetes, logistic regression test was applied. Only fasting blood sugar and 1 hr blood sugar were predictors for developing diabetes from the impaired glucose tolerance group at initial examination.

The Marcus ankle arthrodesis was carried out in 16 patients at department of orthopaedic surgery of Korea Veterans Hospital from January 1989 to December 1993. All of patients were reviewed and evaluated with subjective and functional rating scales according to the Mazur scoring system. The average follow up was 23 months, ranging from 12 months to 60 months. The Marcus ankle arthrodesis involves a chevron osteotomy, tibial onlay graft medially, internal fixation with staples and screws. According to the Mazur score, the results were 6 cases of Excellent, 7 cases of Good. The average Mazur score was 75.1. There were 4 cases of complication, a non-union, a superficial wound infection, a bursitis, and a tendon injury. In summary the Marcus ankle arthrodesis by chevron osteotomy seems to be a good procedure, which gives solid bony union with short duration, relief of pain, normal looking ankle configuration without leg length discrepancy and good function with few complications.

BACKGROUND: We have hypothesized that, if a low resistant gravity-flow membrane oxygenator is used, then the twin blood sacs of TPLS can be located at downstream of the membrane oxyenator, which may double the pulse rate at a given pump rate and increase the pump output. The purpose of this study was to determine the optimal configuration for the ECLS circuits by using the concept of pulse energy and pump output. MATERIAL AND METHOD: Animals were randomly assigned to 2 groups in a total cardiopulmonary bypass model. In the serial group, a conventional membrane oxygenator was located between the twin blood sacs. In the parallel group, the twin blood sacs were placed downstream of the gravity-flow membrane oxygenator. Energy equivalent pressure (EEP) and pump output were collected at pump-setting rates of 30, 40, and 50 BPM. RESULT: At the given pump-setting rate, the pulse rate was doubled in the parallel group. Percent changes of mean arterial pressure to EEP were 13.0+/-1.7, 12.0+/-1.9 and 7.6+/-0.9% in the parallel group, and 22.5+/-2.4, 23.2+/-1.9, and 21.8+/-1.4% in the serial group at 30, 40, and 50 BPM of pump-setting rates. Pump output was higher in the parallel circuit at 40 and 50 BPM of pump-setting rates (3.1+/-0.2, 3.7+/-0.2 L/min vs. 2.2+/-0.1 and 2.5+/-0.1 L/min, respectively, p=0.01). CONCLUSION: Either parallel or serial circuit configuration of the ECLS generates effective pulsatility. As for the pump out, the parallel circuit configuration provides higher flow than the serial circuit configuration.

Deep infection is the most serious complication of total hip arthroplasty with difficulty to treat and occasionally results into catastrophic consequences. The treatment methods are antibiotics, incision & drainage of the hip, debridement & modified Girdlestone resection arthroplasty, one stage revision to total hip arthroplasty, two stage revision and hip disarticulation. The purpose of this report is to consider the treatment of the infected total hip arthroplasty. Since 1979, we have treated 12 cases of infected arthroplasty including 6 cases from other hopital. Duration of interval between primary hip arthroplasty and diagnosis of infection were average 42,4 months(minimum 2 months to maximum 16 years). The results were as follows; 1. The incidence rate of the infected total hip arthroplasty was 1.3%. 2. By Fitzgerald classification, 2 cases were in acute stage, 6 cases in delayed stage and 4 cases in late stage. 3. The causative organisms were coagulase negative Staphylococcus aureus in 6 cases, Staphylococcus hemolyticus in 2 cases, Pseudomonas in 1 case and negative culture in 3 cases. 4. Increased uptake on Bone Scan in all 12 cases and increased ESR ranged from 28mm/hr to 82mm/hr. 5. Our treatment methods were secondary revision to total hip arthroplasty with cement bead insertion in 4 cases, primary revision in 1 case, incision & drainage of hip in 1 case, debridement & modified Girdlestone resection arthroplasty in 2 cases and hip disarticulation in 2 cases. And the rest 2 cases have been followed up after modified Girdlestone resection arthroplasty because of the remained infection. In our experience, two stage revision to total hip arthroplasty with antibiotics mixed cement bead was more useful in the treatment of the infected total hip arthroplasty.

To study the relationship between the urinary hippuric acid and subjective symptoms in toluene exposed workers, urinary hippuric acid was measured and subjective symptoms questionnarire was surveyed in 93 toluene exposed male workers and 96 non-exposed office male workers. The results are as follows: 1. Mean concentration of urinary hippuric acid, which is significantly higher in exposed group than in non-exposed group, was 1.3 g/l, 1.2(GM, GSD respectively) in exposed group and 0.6 g/l, 1.2(GM, GSD respectively) in non-exposed group. 2. Mean concentration of toluene in the air in the workplace, which is significantly higher in the department of coater than in the department of mixing, was 23.4 ppm, 6.2(GM, GSD respectively) in the department of mixing and 59.8 ppm, 3.4(GM, GSD respectively) in the department of coater. 3. Complained rates of subjective symptoms were significantly higher in exposed group than in non exposed group in all items. 4. In exposed group, complained rate of CNS related symptoms was higher than that of irritation related symptoms in the first part but there was no significant difference and complained rate of irritation related symptoms in the second part was significantly higher than that of CNS related symptoms. 5. In exposed group, complained rates of subjective symptoms were not compatible with dose-response relationship by the concentration of urinary hippuric acid, duration of work, department of work, and age group retrospectively.

Radiation therapy is an effective cancer treatment modality as a primary treatment in early cancer and as an adjuvant treatment in advanced cancer, especially in head and neck lesions, but it also causes irreversible chronic damages to overlying normal tissues that may lead to wound complications. As well, at the microscopic level, radiation injury causes both stasis and occlusion of small vessels. Therefore, surgical reconstruction of previously-irradiated lesions in the head and neck poses a great problem. Fifth-six patients with head and neck lesions underwent 57 microsurgical reconstructions between 1990-1998. Thirteen patients were irradiated before surgery. The previous radiation dose was 30-75.6 Gy. The free tissue transfer was successful in 52 of the 57 microsurgical reconstructions(91.2%). The success rate was 92.3%(12/13) in previously-irradiated patients and 90.9%(40/44) in nonirradiated patients. Postoperative complications, such as flap loss, fistula, and infection, developed in 4 irradiated patients and 8 nonirradiated patients. Overall complication rate was 30.8%(4/13) in previously-irradiated patients and 18.2%(8/44) in nonirradiated patients. Although the failure rate of previously-irradiated patients was higher than that of nonirradiated patients, there was no statistically significant difference between them. Thus, free tissue transfers in patients with previously-irradiated head and neck lesions are suitable for one-stage reconstruction.
