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: The accuracy of bacteriologic diagnosis of beta-hemolytic streptococcal pharyngoton sillitis depends on the degree of carrier rate in that area. It is the purpose of this study to obtain the carrier rate from seven different areas and to find results and epidemiologic factors. METHODS: Throat swab was obtained from the tonsillar fossa of normal school children during March through May 1996. It was then plated on a 5% sheep blood agar plate and incubated overnight at 37 degrees C before examination for the presence of beta-hemolytic colonies. RESULTS: The carrier rate of beta-hemolytic streptococci and group A streptococci were 27.6%, 20.0% at Uljin; 16.3%, 6.3% at Checheon; 16.4%, 2.7% at Seoul; 12.8%, 3.4% at Masan; 33.0%, 26.0% at Osan; 20.0%, 12.3% at Kunsan; and 17.7%, 11.4% at Chongju, respectively. Among 2,159 normal school children from 7 different areas, we obtained 450 plates of beta-hemolytic streptococci. Osan had the highest carrier rate (33.3%) and Masan had the lowest rate (12.8%) of beta-hemolytic streptococci. Among 450 plates of beta-hemolytic streptococci, we obtained 265 strains of group A streptococci. Osan had the highest carrier rate (26.0%) and the Seoul had the lowest rate (2.7%) of group A streptococci. CONCLUSION: Higher carrier rates were found in Uljin and Osan, where there is a lower population density. We supposed that low carrier rates might be related to antibiotic abuse or some epidemiologic factor should be investigated.
