이 연구에서는 뇌성마비 아동들에게 적용된 집중 치료적 중재가 대상자들의 기능적 독립성에 어떠한 영향을 미치는지 규명하고자 하였다. A광역시에 소재한 재활전문병원 집중 재활치료에 참가한 아동들 중독립보행이 가능한 26명(남아 16명; 여아 10명)으로부터 수집된 자료를 분석하였다. 평균 치료기간은 9.58주였으며 대상자들의 평균 연령은 65.08개월(SD=37.55)이었다. 아동들의 기능적 독립성을 평가하는 6개 항목 중 ‘장소 옮기기’와 ‘사회적 인지’에서는 치료 전후 사이에 차이가 없었던 반면, ‘신변처리’, ‘대소변조절’, ‘이동하기’, 그리고 ‘의사소통’과 관련된 독립성이 유의하게 향상된 것으로 나타났다. 추가로 집중치료 후 보호자가 판단하는 아동의 독립성 수준을 조사하여 그 결과를 제시하였다. The primary concern of this study was to examine the effect of intensive therapeutic intervention on the functional independence of children with cerebral palsy. The data from 26 children (16 boys and 10 girls) were used for this study after excluding children who could not walk independently rather relied on a wheelchair or a crutch. The average period of the therapy was 9.58 weeks and the average age of children was 65.08 months (SD=37.55). The significant differences were found on ‘Self-Care’, ‘Sphincter-Control’, ‘Locomotion’, and ‘Communication’ factors while changes in ‘Mobility-Transfer’ and ‘Social-Cognition’ were not significant. In addition, the guardians’ attitude to the therapy and the recognition levels on the functional independence of their children were provided.

The human's biomechanical structure keeps an optimal state by adapting the original biomechanical structure according to a change in the physical environment. This phenomenon is believed to be the main cause of loosening of the total hip replacement which is used widely in these days. In this study the bone density change due to artificial hip joint, which is generally believed as bone-remodeling, was investigated by the finite element method. For this, 2-D FEM models with 4 nodal point elements were constructed for intact and implanted cases. The density was calculated by comparing the relative amounts of effective stress for these two cases. In this way, calculated new density values were used in the next step as input values and this procedure repeated until convergence was obtained. Severe density change was detected at the femoral cortex of the proximal-medial side as expected. Moreover, following surprising result was found from this analysis. Titanium alloy prosthesis showed less density change compared to stainless steel prosthesis at earlier stage, however, almost same amount of the density change was detected at final stage. It was also found that other design parameters could not significantly affect its density change.

Fulminant type 1 diabetes is characterized by an abrupt onset, severe diabetic ketoacidosis at diagnosis and a relatively low HbA1c. Rhabdomyolysis is not uncommonly combined with diabetic ketoacidosis or hyperglycemic hyperosmolar coma. Rhabdomyolysis increases the development of acute renal failure and mortality of the patients with hyperglycemic diabetic emergency. A 34-year-old man presented with 2-days duration of oliguria, vomiting and lethargy. Formerly, he developed polyuria and flu-like symptoms such as generalized myalgia and headache for 7 days. Initial investigation showed metabolic acidosis (arterial pH 7.093, bicarbonate 5.1 mmol/L), severe hyperglycemia (glucose 1,576 mg/dL), a relatively low HbA1c (7.1%) and acute renal failure (blood urea nitrogen 77 mg/dL and creatinine 4.4 mg/dL). Both serum and 24-hour urine C-peptide levels were checked at very low range and islet autoantibody tests were all negative. Serum creatinine kinase was elevated to 2,397 U/L and urine myoglobin test was positive. The patient recovered from acute renal failure and rhabdomyolysis after fluid and insulin therapy. He discharged on admission 17th days and controlled diabetes by self injection of basal and bolus insulin. (Korean Clinical Diabetes J 11:79-85, 2010)
