Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

Cardiac resynchronization therapy is effective in selected patients with symptomatic left ventricular dysfunction. Coronary sinus dissection is a relatively uncommon, but much feared, complication that may occur during placement of the left ventricular pacing lead. A 68-year-old man was transferred to our hospital for treatment of severe heart failure. He developed coronary sinus dissection after balloon dilatation during the procedure for cardiac resynchronization therapy. Nevertheless, we successfully placed the left ventricular pacing lead in the coronary vein. We present the case with a review of the literature.

OBJECT: This cross-sectional study was performed in order to evaluate the prevalence of tardive dyskinesia among the hospitalized schizophrenic patients. METHODS: Four hundred nineteen hospitalized schizophrenic patients(male=263, female=156) were recruited for this study. They were treated with antipsychotics for more than 3 months. The prevalence of tardive dyskinesia was assessed by the Abnormal Involuntary Movement Scale. RESULTS: The prevalence of tardive dyskinesia was 35.6%(Male=36.9%, Female 33.3%). There were no significant differences in the prevalence of tardive dyskinesia among male and female schizophrenic patients. The prevalence of tardive dyskinesia among the patients over 30years old was much higher than those below 30years old. There were no significant correlations between the prevalence of tardive dyskinesia and the duration of hospitalization, the total amount of antipsychotics. The frequently involved parts of the body in the schizophrenic patients who have tardive dyskinesia were tongue, upper extremity, lips and perioral area, jaw, lower extremity, muscles of facial expression trunk, respectively. CONCLUSIONS: There was significant correlation between the age and the prevalence of tardive dyskinesia in the antipsychotic-treated schizophrenic patients.

BACKGROUND/AIMS: Albuminuria is an early indicator of renal damage in type 2 diabetes mellitus, and has been recognized as a risk factor for peripheral arterial disease (PAD). The aim of this study was to assess the association between albuminuria and PAD in Korean type 2 diabetes patients. METHODS: Our retrospective study included 390 consecutive patients with type 2 diabetes mellitus. The ankle-brachial index (ABI) and toe-brachial index (TBI) were used to assess PAD. The urinary albumin-creatinine excretion ratio (UAE) was evaluated by determining the albumin/creatinine ratio (ACR) in the first voided morning urine sample. RESULTS: Duration of diabetes, serum creatinine levels, and UAE were significantly higher in patients with low ABI scores (< 0.9) than in those with normal ABI scores (> or = 0.9). Age, duration of diabetes, and UAE were significantly higher in patients with low TBI scores (< 0.6) than in those with normal TBI scores (> or = 0.6). Albuminuria was independently associated with low ABI (OR = 1.980, 95% CI = 1.001-3.918). It was also independently associated with low TBI and normal ABI (OR = 3.149, 95% CI = 1.260-7.871). CONCLUSIONS: The results of this study suggest that albuminuria may be associated with PAD, including in arteries distal to the ankle joint.

PURPOSE: The objective of this study was to find the predictors and generate a prediction scoring model of nonresponse to intravenous immunoglobulin in patients with Kawasaki disease. METHODS: We examined 573 children diagnosed with KD at the Severance Children's Hospital between January 2009 and december 2012. We retrospectively reviewed their medical records. These patients were divided into 2 groups; the experimental group (N=433) and the validation group (N=140). Each group were divided into 2 groups the intravenous immunoglobulin nonresponders and the responders. Multivariate logistic regression analysis identified predictive factors of intravenous immunoglobulin nonresponders which make predictive scoring model. We practice internal validation and external validation. RESULTS: Multivariate logistic regression analysis identified male, cervical lymphadenopathy, changes of the extremities, platelet, total bilirubin, alkaline phophatase, lactate dehydrogenase, C-reactive protein as significant predictors for nonresponse to intravenous immunoglobulin. We generated prediction score assigning 1 point for (1) male, (2) cervical lymphadenopathy, (3) changes of the extremities, (4) platelet (< or =368,000/mm3), (5) total bilirubin (> or =0.4 mg/dL), (6) alkaline phophatase (> or =227 IU/L), (7) lactate dehydrogenase (> or =268 IU/L), (8) C-reactive protein (>77.1 mg/dL). Using a cut-off point of 4 and more with this prediction score, we could identify the intravenous immunoglobulin nonresponder group. Sensitivity and specificity were 52.5% and 82.4% in experimental group and 37.8% and 81.8% in validation group, respectively. CONCLUSION: Our predictive scoring models had high specificity and low sensitivity in Korean patients. Therefore it is useful in predicting nonresponse to intravenous immunoglobulin with Kawasaki disease.

The transarterial embolization has been widely used to control bleeding. It has a variety of clinical utility; to reduce bleeding on the surgical field, to reduce the size of malignant tumor as a preopearative treatment, to treat arteriovenous malformation or arterial aneurysm as a curative method and to promote life qua' ity of patient with diffuse or multiple hepatocellular carcinoma as a palliative treatment, etc. With the advance of modem technology, various embolic materials have been also developed. IIowever, it has not- been -fully investigated of histopathologic changes of the embolized organs according to the embolic materials used. This study was undertaken to investigate the histopathologic changes of embolized renal artery in rabbit by various embolic materials, according to each embolic material and to time passed by after embolization. Of the 5 arteries embolized by ethylene vinyl alcohol copolymer(EVAL), one showed abscess formation in embolized kidney. The other 4 allowed to perform further pathologic study: within a week after embolization there was no any specific change in vessels, however, r,unimal endothelial hypertrophy was observed following 2 weeks of embolization. Of the 8 renal arteries embolized by N-buthyl-2-cyanoacrylate(Histoacryl), 4 showed total occlusion of the main renal arteries as well as renal infarction, which reflects the strong adhesiveness of Histoacryl to vascular wall. The other 4 showed fibrinoid degeneration in vascular wall within a week. However, further change was not observed thereafter. In all the 5 renal arteries embolized by polyvinyl

BACKGROUND: Conventional echocardiography provides fundamental information about mitral valve morphology and function but is often subjective and has a relatively low specificity in evaluating valve calcific deposit, which is critical information for the preoperative decision. We hypothesized that mitral valvular calcification could be detected in standard two-dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis so that we could overcome the subjectivity and low specificity of conventional echocardiography. METHODS: We tested this hypothesis by performing standard 2.5MHz two-dimensional echoes on mitral valve and myocardium in 30 patients with mitral stenosis, scheduled to undergo mitral valve replacement. We compared gray level of each region of interest in mitral valve and myocardium in stop-frame images with the degree of calcifications identified by pathologic and radiographic examinations. RESULTS: Ratio of mean gray level of mitral valve to mean gray level of myocardium was the most reliable value in evaluating degree of calcification. Quantitatively, region of calcification displayed the ratio of significantly higher value than that of no calcification. In case of anterior mitral valve, the ratio of the evident calcified region was greater than 3.11, that of the region without calcification was less than 2.42 and that of microcalcification was betwwn 2.42 and 3.11. For posterior mitral valve, the ratio of the evident calcified region was greater than 3.50, that of the region without calcification was less than 2.19 and that of microcalcification was between 2.19 and 3.50. The sensitivity and specificity of this method for assessment of degree of calcification was 75% and 100% for anterior mitral valve and 9% and 87.5% for posterior mitral valve. CONCLUSION: Mitral valvular calcification could be detected quantitatively in standard two dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis.

We have applied the intraoperative use of Perfluorophenanthrene (C14F24) liquid in 19 eyes of complicated retinal detachment surgery in 19 patients since November 1990 to October 1991. The vast majority of case of retinal detachment was trauma (9 eyes) and uveitis including pars planitis (6 eyes) remainders were juvenile retinoschisis, cataract surgery, myopIa, diabetes one eye each. The grade-D of proliferative change was found in 9 eyes (D1 3 eyes, D2 3 eyes, D3 3 eyes) and 8 eyes belong to over grade-C2 (C2 4 eyes, C3 4 eyes). Multiple anterior retinal tears were found in two. Giant retinal tear was noticed in 5 eyes and the other one was made on therapeutic purpose. Intraoperative reattachment was obtained in all eyes. The follow-up periods were 6 or more (mean 9.1) months. At last follow-up, the retina was attached in 12 eyes (63%), partially attached in 2 (10%) and redetached in 5 (26%). Visual acuity was improved or same in 12 eyes (63%), became worse in 7(37%). Visual acuity of 0.02 or better was obtained in 12(63%) eyes and 3(16%) saw 0.1 or better. Perfluorophenanthrene liquid was thought as non-toxic, heavy biomaterial and effective to treat the complicated retinal detachments.
