Reverse total shoulder arthroplasty has been performed with promising results in rotator cuff tear arthropathy. However, the global complication of the reverse total shoulder arthroplasty is relatively higher than that of the conventional total shoulder arthroplasty. Neurologic complications after reverse total shoulder arthroplasty are rare but there are sometimes remaining sequelae. The cause of the neurologic complication is multifactorial, including arm traction, position and the design of the implant. Most cases of neurologic palsy following reverse total shoulder arthroplasty occur in the axillary nerve and the radial nerve. The authors report on a case of a 71-year-old man with isolated musculocutaneous nerve palsy after reveres total shoulder arthroplasty with related literature.

Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

PURPOSE: To identify the changes of bony landmarks with rotation and to compare the reliability and accuracy of Perdriolle's method before and after training on the exact bony landmarks. MATERIALS AND METHODS: Simple A-P radiographs were taken with rotation from 5 degree to 50 degree at 5 degree interval using 10 dry human vertebrae (2 sets of T3, T6, T9 8 L3) with no bony abnormality. Axial rotation was measured before and after training on the exact bony landmarks by three observers, twice for each radiographs. Repeated measures of ANOVA were used for inter- < intraobserver variance and regression analysis for root mean square error and deviation of differences. RESULTS: Mamillary process, inner margin of lamina, proximal and distal costovertebral joints, upper margin of concave pedicle and tip of the transverse process on the convex side confused the exact outline of the pedicle, while neural foraminal margin was helpful in identifying the location of the indistinct convex pedicle and concave vertebral border. Of the 660 measurements before and after training 372 and 397 errors were made, respectively, of which 88.9% and 88.5% were within +/-5 degree(P > 0.05). Incidence of error greater than 5 degree was high at upper thoracic vertebra and 20 degree-40 degree of rotation regardless of training. The effects of training, however, was greatest at T3 and 20 degree-40 degree of rotation. Inter- < intraobserver variance was diminished at T3 and at the rotation between 20 degree-40 degree after training. CONCLUSIONS: We could conclude that training on the exact bony landmarks did not reduce the overall error incidence. Accuracy and reliability, however, was increased at T3 after training and the efficacy of training was more evident in moderate vertebral rotation than in small or large vertebral rotation.

OBJECTIVES: The aim of this study was to investigate mortality rates and risk factors in dementia patients in a rural cohort. METHODS: A total of 114 subjects with clinically diagnosed dementia were followed up for eight years from 1997 to 2005. Their mortality was compared with sociodemographic and clinical variables using the Cox proportional hazards models after adjusting age, sex, and education. RESULTS: During follow-up, the mortality rate of subjects was 80.2% and the mean (SD) duration of survival from at diagnosis to death was 4 years. Mortality in subjects with dementia depended on old age (relative risk [RR] : 1.05 ; 95% confidence interval [CI] : 1.01-1.08), male (RR : 1.61 ; CI : 1.00-2.59), low Clinical Dementia Rating scale (RR : 1.54 ; CI : 1.14-2.10), low Activities of Daily Living (RR : 0.72 ; CI : 0.59-0.89), low Instrumental Activities of Daily Living (RR : 0.83 ; CI : 0.75-0.92), no physical activity (RR : 0.44 ; CI : 0.28-0.70), smoking (RR : 1.74 ; CI : 1.05-2.89). CONCLUSION: Mortality in dementia depended on age, sex, CDR, ADL, IADL, physical activity, smoking. These findings have important implications that contribute to make the disease management of dementia patients.

Nesidioblastosis is characterized by a diffuse proliferation of islet cells arising from pancreatic ducts and is the most common cause of hyperinsulinemic hypoglycemia in newborns and infantile. It is exceedingly rare in adults and no concensus regarding its diagnosis and management is available. We herein describe an elderly man with fasting hypoglycemia, inappropriate insulin hypersecretion. And pathologic examination of his pancreas revealed the characteristic finding of nesidioblastosis confirmed by immunohistochemical stain.

PURPOSE: Metabolic syndrome (MS) is a clinical condition that shares many common characteristics with diabetes. However, unlike diabetes, the usefulness of MS as a prognostic entity in peripheral arterial disease is uncertain. This study evaluated the prognostic usefulness of MS in critical lower limb ischemia (CLI) patients. MATERIALS AND METHODS: We compared the 2-year clinical outcomes in 101 consecutive CLI patients (66+/-14 years; 78% men) with 118 affected limbs treated with percutaneous transluminal angioplasty (PTA) according to the presence of MS and diabetes. RESULTS: The number of MS patients was 53 (52%), of which 45 (85%) had diabetes. During a 2-year follow-up, the incidence of clinical outcomes, including reintervention, major amputation, minor amputation, and survival, was not significantly different between MS and non-MS patients; however, the incidence of minor amputation was significantly higher in diabetic than in non-diabetic patients (42% vs. 17%; p=0.011). Cox regression analysis for the 2-year primary patency demonstrated no association between MS and 2-year primary patency [hazard ratio (HR), 1.02; 95% confidence interval (CI), 0.45-2.30; p=0.961], whereas there was a significant association between diabetes and 2-year primary patency (HR, 2.81; 95% CI, 1.02-7.72; p=0.046). Kaplan-Meier analysis revealed no significant difference in the 2-year primary patency between MS and non-MS patients; however, the 2-year primary patency was lower in diabetic than in non-diabetic patients (p=0.038). CONCLUSION: As a prognostic concept, MS might conceal the adverse impact of diabetes on the prognosis of CLI patients treated with PTA.

BACKGROUND: Conventional visual assessment of coronary arteriogram is fraught with large interobserver variance and disagreement with pathologic findings. Thus quantitative coronary angiography had been recently developed to meet the requirement of more reproducible measurement of severity of coronary artery disease. This study was designed to evaluate the interobserver variability of quantitative coronary angiography and its usefulness in clinical application. METHODS: Three independent observers analysed coronary angiogram of 31 consecutive patients by visual assessment and quantitative measurement using computer based algorithm. RESULTS: 1) There was considerable disagreement between 3 observers in the identification of significant coronary stenosis. Complete agreement was achieved in only 29/61 (47%) coronary lesion and agreement of more than 2 observers in 41/61(67%) lesion. 2) In visual assessment, the largest interobserver variance was found in acute marginal artery and distal circumflex artery, whereas the least variance was observed in proximal right coronary artery. 3) The average interobserver variance was 13.1% in visual assessment, 14.9% in geometric analysis, and 10.5% in video densitometric analysis. There was no significant difference between these values. 4) Visual assessment was noted to overestimate the severity of stenotic lesion, by 5.6% compared to geometric analysis and by 11.8% compared to video-densitometric analysis. CONCLUSION: These findings suggest that identifying significant lesion is major source of interobserve variability in both visual and quantitative analysis of coronary arteriogram. In addition, suboptimal image quality was responsible for the inability of quantitative analysis to reduce the variance. These factors seem to be major limitation of quantitative coronary arterirogam.
