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.

BACKGROUND: Numerous procedures are available for nipple reconstruction without a single gold standard. This study presents a method for reducing donor-site morbidity in nipple reconstruction using a composite nipple graft after transverse rectus abdominis musculocutaneous flap breast reconstruction. METHODS: Thirty-five patients who underwent nipple reconstruction using a composite nipple graft technique between July of 2001 and December of 2009 were enrolled in this study. To reduce the donor site morbidity, the superior or superior-medial half dome harvesting technique was applied preserving the lateral cutaneous branch of the fourth intercostal nerves. The patients were asked to complete a previously validated survey to rate the color and projection of both nipples, along with the sensation and contractility of the donor nipple; and whether, in retrospect, they would undergo the procedure again. To compare projection, we performed a retrospective chart review of all the identifiable patients who underwent nipple reconstruction using the modified top hat flap technique by the same surgeon and during the same period. RESULTS: Thirty-five patients were identified who underwent nipple reconstruction using a composite nipple graft. Of those, 29 patients (82.9%) responded to the survey. Overall, we received favorable responses to the donor site morbidity. Projection at postoperative 6 months and 1 year was compared with the immediate postoperative results, as well as with the results of nipples reconstructed using the modified top hat flap. CONCLUSIONS: The technique used to harvest donor tissue is important. Preserving innervation of the nipple while harvesting can reduce donor site morbidity.

PURPOSE: To compare T2-weighted MR cholangiography (T2-MRC) and contrast-enhanced T1-weighted MRC (enhanced T1-MRC) in the assessment of biliary anatomy in donor candidates for living related liver transplantation (LRLT). MATERIALS AND METHODS: Thirty-three potential donors underwent MR examination for preoperative evaluation. Using the single-shot half-Fourier RARE sequence, T2-weighted single-section and coronal images were obtained, and enhanced T1-MRC was performed, using 3D GRE sequences after the administration of mangafodifir trisodium. To assess the hilar ductal branching pattern and determine diagnostic confidence, two reviewers first evaluated the unpaired T2-MRC and enhanced T1-MRC images, and then paired T2-MRC and enhanced T1-MRC images together. In particular, in 12 cases in which direct cholangiographys were performed, the feasibility of single duct-to-duct anastomosis was assessed using the unpaired and the paired sets sequentially. RESULTS: The reviewers' confidence tended to be higher for enhanced T1-MRC than T2-MRC, but the difference was not statistically significant. For both reviewers, confidence was significantly higher for the paired set than for T2- or enhanced T1-MRC alone (p < .001). The types of biliary anatomy determined in the paired set matched the consensus reading in 33 (100%) and 30 cases(91%) assessed by reviewer 1 and 2, respectively. The separate interpretation of T2- and enhanced T1-MRC findings matched the consensus interpretation in 30 (91%) and 28 cases (85%), respectively, assessed by reviewer 1, and 26 (79%) and 28 cases (85%), respectively, assessed by reviewer 2. The possibility of single anastomosis was accurately predicted in 91.6% of cases in T2-MRC, and 100% at enhanced T1-MRC and the combined set. CONCLUSION: In the evaluation of the biliary anatomy of potential donors for LRLT, the combined use of T2-MRC and enhanced T1-MRC may improve diagnostic confidence and decrease the occurrence of a non diagnostic or equivocal interpretation at T2-MRC alone.
