Twenty nine cases of segmental tibial fracture were treated at Ewha Womans University Hopital, Department of Orthopedic Surgery, during the period from January, 1970 to December, 1984. The following results were obtained. 1. Most common fracture level was type I, high middle segment, occurred about 12 cases (41.4%). 2. In view of the higher incidence of open fracture (16 cases, 55.1%) and comminuted fracture (22 cases, 75.9%), fracture was caused by high velocity. 3. Various external and internal fixation methods were applied, but higher union rate was seen in the cases of Küntscher nailing and plating with bone graft. 4. Excluding the cases of type V, average union rate was 28.5 weeks and open fracture (ave. 29.6 weeks) required more longer union rate than closed fracture (ave. 26 weeks). 5. Higher rate of complication (21 cases, 72.4%) was noted than other types of tibial fracture. 6. Good result was obtained for treatment of 5 cases of delayed union or non-union by plating and bone graft than any other methods.

BACKGROUND: Caudal anesthesia has gained wide acceptance in pediatric anesthesia as a technique for providing postoperative pain relief and reducing general anesthetic requirement for surgical procedures below umbilicus. Although blood pressure has been shown to be well maintained with caudal anesthesia in pediatrics, little is known about the change in hemodynamics with combined general and caudal anesthesia. This study was designed to investigate the hemodynamic changes of combined general and caudal anesthesia for lower abdominal surgery in children. METHODS: Sixty children scheduled for lower abdominal surgery were involved. They were randomly divided into 2 groups: group G (n = 30); anesthesia with enflurane and N2O, and the group GC (n = 30); anesthesia with combined caudal block using 1% lidocaine 1 ml/kg and enflurane. Systolic (SBP), diastolic (DBP), mean blood pressure (MBP), and heart rate (HR) were measured at the 6 different time periods; at before induction (T1), just before skin incision (T2), just after skin incision (T3), 5 min (T4), 10 min (T5), and 30 min (T6) after skin incision. RESULTS: There were no significant differences in variables of hemodynamics between both group. Compared with the values at T1, those of SBP, DBP, and MBP at T2, T3, T4, T5, and T6 were decreased in both groups. However, there were no difference in those values at the same time periods between the two groups. The values of SBP, DBP, and MAP at T3, T4, T5, T6 in group G were higher compared with those at T2. CONCLUSIONS: From these results, we concluded that there were no significant changes in hemodynamics by combined general and caudal anesthesia in pediatric patients.

BACKGROUND & METHODS: Approximately 10% of the essential hypertensive patient have overt proteinuria due to renal target organ damage, which indicates poor prognosis. Recently microalbuminuria has been prove to be a good early predictor for renal damage in patients with diabetes or hypertension. Some authors reported that near 40% of the essential hypertensives have microalbuminuria. To determinate prevalence of microalbuminuria in Korea essential hypertensives, 24-hr ambulatory blood pressure monitoring and radioimmunoassay to detect BP and UAER were performed after 4 weeks wash-out period in 137(78 hypertensive and 54 normotensive) consecutive cases. RESULTS: Among 78 hypertensives, overt proteinuria was seen in 8.97%(7/78). And prevalence of microalbuminuria were 29.4%(23/78) in hypertensives and 16.7%(9/54) in normotensives. Urine microalbumin excretion rate(UAER) was significantly correlated with mean arterial pressure(MAP) in total subjects(r=0.286, p=0.0012), but not in total hypertensives(r=0.135, p=NS) or in hypertensives with UAER(r=-0.098, p=NS).UAER of female hypertensives was increase than that of male hypertensives(13.17+/-16.28microg/min vs 22.87microg/min, p=0.027). CONCLUSION: Prevalence of microalbuminuria in Korean hypertensives was relatively lower then other reports. Overt proteinuria was noted in 8.97% of the hypertensives which is same prevalence as other countries. Moreover MAP was well correlated with UAER in total subjects. Further evaluation should be done to detect exact role of UAER in hypertensives as an early predictor for renal target organ damage.

Mucopolysaccharidoses are a group of inherited disorders of metabolism resulting in the deposition of mucopolysaccharide in various tissues. This leads to organ dysfunction and anatomical abnormalities which can be important to the anesthetist. These abnormalities result in airway difficulty and difficult intubation. We successfully performed endotracheal intubation in a case of mucopolysaccharidoses in a 9-year-old female patient using fiberoptic laryngoscopy.

BACKGROUND: Although radiofrequency catheter ablation (RFCA) is useful in the treatment of idiopathic ventricular tachycardia, especially right ventricular outflow tract tachycardia (RVOTT), some tachycardias remain resistant despite several attempts. This study was focused to search of electrocardiographic characteristics suggestive of successful radiofrequency ablation of idiopathic ventricular tahycardia showing LBBB and inferior axis. MATERIALS AND METHODS: The study subjects were 19 patients (mean age 4415, male 5, female 14) those we tried RFCA under the diagnosis of RVOTVT. The study subjects were grouped into success group (N=14) and failed group (N=5). We analyzed the morphologic characteristics of QRS complex during ventricular tachycardias or ventricular premature beats in both groups. RESULTS: Acute success was obtained in 14 of 19 patients. For RFCA of RVOTT, pace mapping and/or activation mapping were used to select an ablation site as described previously(1). Activation mapping was possible only for 5 patients. All patients except one patient of success group showed inferior axis of QRS during VT. We didn't find significant difference in QRS axis, QRS morphologies in lead 1 and aVL, and QRS width in lead II and V2 between success (N=14) and failed group (N=5). However, in analysis of morphologic comparison of precordial leads, 12 out of 14 patients in success group showed initial r wave in V1 (p=0.017) and 11 patients had precordial transition >V3 (p=0.038). Whereas, in failed group, 4 patients had precordial transition V3 and only one patient showed precordial transition >V3. Initial r of V1 was seen in one patient and remaining 4 patients showed QS pattern in V1. CONCLUSION: Analysis of QRS morphology in V1 and precordial transition site may identify patients with high and low success rate during RFCA of idiopathic RVOTT

BACKGROUND: Persistent facial telangiectasia, erythema and flushing are the major cosmetic problems in patients with rosacea. However various therapeutic treatments for rosacea papules and pustules are not effective in reducing telangiectasia and flushing reactions. Matrix-centered theory that dermal matrix degradation can cause telangiectasis, erythema and flushing, is one of the various theories of rosacea pathogenesis. Shark cartilage extracts are collagenase inhibitors and can inhibit dermal matrix degradation. OBJECTIVE: The purpose of this study was to evaluate the clinical effects of shark catilage extracts (Venatrix(R)) for erythematotelangiectatic rosacea patients. METHODS: Twenty three patients with erythematotelangiectatic rosacea applied shark cartilage extracts twice daily for up to 8 weeks. Efficacy was evaluated by erythema index using mexameter (MPA 5, CK, Germany) and clinical photography. RESULTS: Erythema index decreased from 525.7+/-114 to 413.9+/-101.7 (mean reduction: 21.3%) (p<0.1) after 8 weeks treatment. 16 patients (69%) showed excellent or good results by clinical photography. Transient stinging sensation was the most common adverse effect and these symptoms improved after the first few days. There were no other significant side effects. CONCLUSION: Shark cartilage extracts may be an effective treatment for mild erythematotelangiectatic rosacea.

BACKGROUND: Low dose dobutamine echocardiography has recently been introduced for use in identification of viable myocardium in patients with acute myocardial infarction and prediction of the response of dysfunctioning myocardial segments to coronary angioplasty. The aim of this study was to evaluate wheter tihs test could be used to predict the early response of dysfunctioning myocardial segements to coronary artery bypass grafting(CABG). METHODS: We studied in 23 patients with multi-vessel disease during CABG. Myocardial segments were monitored by intraoperative transesophageal echocardiography(TEE) in the transgastric short-axis view at papillary muscle level. The left ventricle was divided into five segments and sixty eight myocardial segments in 23 patients were analyzed. Percentage of systolic wall thickening(PSWT) was calculated in each segment for three times: at basline(early after pericardiectomy);before bypass during dobutamine infusion(3-5ug/kg/min);and after seperation from cardiopulmonary bypass. Segments showing baseline PSWT >_30% were considered normal and those < 30% were dysfunctional. Segments showing an increase in PSWT >_10% during dobutamine infusion were considered responders and those < 10% nonresponders. RESULTS: AT baseline, 24%(36%) of 68 segments had PSWT > 30%(normal) and 44(68%) had PSWT < 30%(dysfuctioning segments). During dobutamine infusion, 21(47.7%) among 44 dysfunctional segments showed increase in PSWT >_10%(from 12.3+/-7.2% to 33.5+/-11.8%, p<0.01 ; responder segments), and 23(52.3%) showed increase in PSWT < 10%(from 14.7+/-6.5% to 17.4+/-7.4%, p=NS ; nonresponder segments). After CABG, responder segments showed a significant increase in PSWT in comparison with baseline values(from 12.3+/-7.2% to 32.1 +/-11.0%,p<0.01). Segments not responded to dobutamine showed no significant changes in PSWT after CABG(from 14.7+/-6.5% to 16.0+/-8.2%, p=NS). Twenty-four normal segments (PSWT 41.9+/-6.2%) showed a slight but significant reduction in PSWT both during dobutamine infusion(38.7+/-6.9%;p<0.05) and after CABG(38.9+/-6.3%, p<0.05), suggesting that compensatory hyperfunction was present at baseline. Estimation of clinical accruacy of low dose dobutamine TEE yieded to 69% sensitivity, 93.9% specificity, 95.2% positive predictive value, 60.9% negavive predictive value, and 77.3% overall accuracy. In both responders and nonresponders of dysfunctioning segments, there was a correlation between PSWT during dobutamine infusion and that after CABG(r=0.61, r=0.63, respectively). CONCLUSION: Low dose dobutamine TEE test well predicts the early response of dysfunctioning myocardial segments to CABG.
