Between 1984 and 1996, 8 patients who were suffered from stage g Kienbock's disease underwent interpositional arthroplasty using pronator quadratus pedicled bone. Patients comprised 2 males and 6 females, with an average age of 33 years(range 19-47). Range of motion of the wrist, residual pain, grip strength, and carpal height ratio of the patients were analyzed. The follow-up period was between 1.5 years and 12.5 years(average 5.5 years). The arc of flexion-extension of the wrist was increased from average 74 degrees preoperatively to 96 degrees postoperatively. Among eight patients, five were free of pain and three had intermittent pain during heavy work. None of eight patients had any discomfort in daily work and changed his or her occupation. The grip strength was average 83% of the normal side. Carpal height ratio was average 0.48 preoperatively and was not changed postoperatively. Clinical results, assessed by Lichtman-Evans criteria, showed 4 good and 4 fair. The interpositional arthroplasty using pronator quadratus pedicled bone was considered as a very effective method for the treatment of stage III Kienbock's disease.

Collagen is the major structural protein in the human body, especially in connective tissues. There are more than 13 types of collagen. Among them, type II collagen is a main component of articular cartilage structure. Altered immunological conditions against type II collagen may be closely related to the pathologic conditions of joint, especially arthritis. Since 1977, animal model for collageninduced arthritis(CIA) has been developed and used in the investigation of arthritis. In those animals, high titers of anti-type II collagen antibody were noticed. Pathologic findings were similar to rheumatoid arthritis of human, which suggested that rheumatoid arthritis might be one of the autoimmune diseases. There had been many reports about elevation of serum and synovial level of anti-type II collagen antibody in rheumatoid arthritis patients. But majority of them did not discriminate the antibody titers according to the type of immunoglobulin(i.e. IgG, IgM). And the question whether the elevated antibody titers are cause or effect of the arthritis is still in controversy. In this study, the serum levels of anti-type II collagen antibody were determined in 82 persons(35 degenerative arthritis patients, 24 rheumatoid arthritis patients and 22 normal controls without any joint problem) via ELISA method. In each person the serum IgG, IgM and IgG+M+A antibody levels against bovine type IIcollagen and chicken typeII collagen were determined individually. Statistical evaluation of these data among degenerative arthritis group, rheumatoid arthritis group and normal control group was performed. The results were as follows; 1. Degenerative arthritis group revealed significant elevation of anti-type II collagen antibody(IgG, IgG+M+A) compared to normal control(p < 0.05). 2. Rheumatoid arthritis group showed significant elvation of IgM and IgG+M+A compared to normal control. 3. Between degenerative arthritis and rheumatoid arthritis group, no sigificant difference was noticed. 4. Rheumatoid arthritis group showed significant increase of IgM antibody level compared to normal control. 5. Female rheumatoid arthritis group showed significant increase of IgM level compared to female degenerative arthritis group. These findings suggested that the elevation of anti-type II collagen antibody titer is not specific for rheumatoid arthritis and related with general pathologies destroying articular cartilage. And it is suggested that anti-type II collagen antibody associated with rheumatoid arthritis is mainly IgM proportion, especially in female patients. So further investigation of anti-type II collagen antibody associated with rheumatoid arthritis is needed to target IgM antibody.

BACKGROUND: Alzheimer's dementia is the most common dementia. However, recently, choline alfoscerate is prescribed for treating Alzheimer's dementia, although it is not a treatment for this disease. PURPOSE: To analyze the prescription patterns of choline alfoscerate as a dementia treatment for patients with Alzheimer's disease and to analyze, as well as the factors affecting choline alfoscerate prescription. METHOD: The 2016 HIRA-NPS data was used in this study. The code of Alzheimer's dementia is F00 in the ICD-10 disease classification code. We analyzed the demographic, clinical, and regional characteristics associated with donepezil, rivastigmine, galantamine, memantine, and choline alfoscerate prescriptions. All statistical and data analyse were conducted by SAS 9.4 and Excel. RESULTS: For patients with Alzheimer's disease, choline alfoscerate was the second most prescribed after donepezil. Analysis results showed that choline alfoscerate was more likely to be prescribed to men than to women, and more likely to be prescribed by local health centers than by medical institutions. Moreover, choline alfoscerate was highly likely to be prescribed at neurosurgical departments, among medical departments. CONCLUSION: This study confirmed that choline alfoscerate was prescribed considerably for patients with Alzheimer's dementia. Further studies valuating its clinical validity should be performed to clarify whether choline alfoscerate prescription is appropriate for treating Alzheimer's dementia.

OBJECTIVES: The purpose of this study was to investigate the clinical utility of the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV) and General Ability Index (GAI) in children with attention-deficit hyperactivity disorder (ADHD). METHODS: The GAI and Full Scale IQ (FSIQ) in K-WISC-IV were compared for a group of 79 children with ADHD and 234 normal children. The mean differences within each group were testified by the t-test and Cohen's d. The Wechsler's descriptive classifications for each GAI and FSIQ score were analyzed in the children with ADHD. Additionally, the critical value for the difference between the means of the FSIQ and GAI was calculated in the normal children. RESULTS: The score on the GAI was higher than that on the FSIQ in the children with ADHD, with a mean difference of 2.19 points. The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. According to Wechsler's descriptive classification, the application of the GAI showed a lower (7.59%), equal (61.65%) or higher (60.76%) prevalence of ADHD compared to the application of FSIQ. CONCLUSION: The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. The GAI reflecting the attention and behavioral problems in children with ADHD could be utilized as an alternative global intelligence estimate that considers their potential for development.

BACKGROUND: The purpose of this study is to assess the validity and reliability of general job satisfaction (JS) in the Korean Labor and Income Panel Study (KLIPS). METHODS: We used the data from the 17th wave (2014) of the nationwide KLIPS, which selected a representative panel sample of Korean households and individuals aged 15 or older residing in urban areas. We included in this study 7679 employed subjects (4529 males and 3150 females). The general JS instrument consisted of five items rated on a scale from 1 (strongly disagree) to 5 (strongly agree). The general JS reliability was assessed using the corrected item-total correlation and Cronbach's alpha coefficient. The validity of general JS was assessed using confirmatory factor analysis (CFA) and Pearson's correlation. RESULTS: The corrected item-total correlations ranged from 0.736 to 0.837. Therefore, no items were removed. Cronbach's alpha for general JS was 0.925, indicating excellent internal consistency. The CFA of the general JS model showed a good fit. Pearson's correlation coefficients for convergent validity showed moderate or strong correlations. CONCLUSION: The results obtained in our study confirm the validity and reliability of general JS.

BACKGROUND:The number of old patients receiving coronary artery bypass grafting(CABG) is increasing. With the more recent advances in operative techniques, the age at which CABG is indicated has also increased. This study evaluated the risk factors associated with the hospital mortality and the morbidity following CABG in elderly patients. MATERIAL AND METHOD: Between March 1991 and June 1998, we retrospectively reviewed 45 consecutive patients aged 65 years or older who underwent CABG. We compared the data with the results of 179 patients under the age 65 years operated during the same period. RESULT: Mean age was 68+/-1.41 years(range 65 to 74 years). Emergency surgery was required in 4, and elective surgery in 41 patients. The mean number of distal anastomosis per patient was 3.62 +/-0.81 and mean aortic cross-cramp time was 69.84+/-18.5 minutes. Thirty patients had Canadian class III or IV preoperatively, but 43 patients had class I or II postoperatively. The left ventricular ejection fraction increased significantly from 54.23+/-10.62% preoperatively to 58.14+/-9.88% postoperatively(p<0.05). Postoperative complication was pneumonia in 2 patients, acute renal failure in 2 patients, sternal wound infection in 1 patient, and postoperative myocardial infarction in 1 patient. There were two postoperative deaths. The causes of deaths were low output syndrome in one patient, and sepsis due to pneumonia in the other patient. The hospital mortality was higher in the elderly group(4.4 versus 2.86%) but was not statistically significant(p>.05). Incremental risk factors for hospital deaths in the elderly were emergent operation, preoperative PTCA, postoperative use of IABP and postoperative ARF(p<0.05). The duration of hospital stay after operation was significantly longer for the elderly group than the younger group(19.27+/-12.51 vs 15.55+/-6.99 days; p<0.05). Follow-up was complete for 34 of the hospital survivors and ranged from 1 to 73 months(mean: 23.58+/-19.56 months). There was no late mortality of cardiac origin. CONCLUSION: Age is an important factor in selecting optimal management for elderly patients with coronary compromise, but age alone should not dictate the choice of therapy. Coronary artery bypass surgery in the elderly is associated with acceptable early mortality and excellent long-term results.

BACKGROUND: Worry, a core feature of anxiety disorder, is shown in not only children with anxiety disorder but also normal children. This study was conducted to determine the relationship between worry and family environment factors, especially, perceived parental rearing and attachment styles among children. METHODS: Five hundred and nine children participated in this study among 549 children in third, fourth, fifth and sixth grades in two primary schools located in Seoul and Seongnam from October 2007 to December 2007. Forty children did not agree with participation (rejection rate: 7.3%). Their degrees of worry, attachment styles and perceived parental rearing were investigated with questionnaires. RESULTS: The reliability of a questionnaire asking children's worry, PSWQ-C and a questionnaire asking perceived parental rearing, modified EMBU-C was appropriate with internal consistency (Cronbach's alpha of PSWQ-C: 0.92, Cronbach's alpha of modified EMBU-C: 0.68~0.89). Around 22.4% of children had insecure attachment (avoidant or ambivalent attachment) and scores of worry were high in both girls and boys. When children perceived their parental rearing behavior as anxious rearing, they were classified to have ambivalent attachment in many cases by themselves. And when they perceived the rearing as rejection many of them were classified to have avoidant or ambivalent attachment by themselves. Worry showed a significantly negative correlation in the cases where children answered their perceived parental rearing as emotional warmth and showed a significantly positive correlation with rejective and anxious rearing. CONCLUSION: This study found that children's worry was closely related with their perceived parental rearing and attachment styles. If the children's attachment, which has been developed while they have grown up, was insecure and they did not perceive parental rearing as emotional warmth, the intensity of worry, a core symptom of anxiety disorder, increased.
