Medial gastrocnemius flap has been known as a useful option for soft tissue reconstruction of the knee and upper 1/3 of lower extremity, but it has a limitation to cover the lateral defect of the knee joint. We performed the combined gastrocnemius-medial sural artery perforator flap for coverage of the anterolateral defects of the knee joint, which is compound flap using a medial gastrocnemius flap and a medial sural artery perforator flap. This flap is a useful method for reconstruction of anterolateral knee defects, providing a easy dissection without the microsurgery and intramuscular dissection of the perforators.

PURPOSE: To compare outcomes of open and arthroscopic inferior capsular shifts in multidirectional instability of the shoulder and to evaluate the factors affecting the outcomes. MATERIALS AND METHODS: We measured outcomes in 81 patients (84 shoulders) receiving open or arthroscopic inferior capsular shifts because of multidirectional instability of the shoulder from February, 1994, to April, 2006. There were 76 males and 8 females. Their mean age was 22 years at the time of surgery. The visual analogue scale (VAS) for pain, shoulder range of motion (ROM), and Rowe scores were evaluated preoperatively and postoperatively. RESULTS: In open surgery, the VAS for pain was 5.3 preoperatively and 2.1 postoperatively. VAS for instability changed from 4.6 to 1.7, and the average postoperative Rowe score was 83.7. Forward flexion was 173.7degrees preoperatively and 166.1degrees postoperatively. External rotation on the side changed from 75.5degrees to 62.7degrees. In arthroscopic surgery, the VAS for pain was 4.6 preoperatively and 1.2 postoperatively. VAS for instability changed from 5.9 to 1.2, and the average postoperative Rowe score was 87.4. Forward flexion was 169.5degrees preoperatively and 171.2degrees postoperatively. External rotation changed from 70.8degrees to 61.4degrees. CONCLUSION: Arthroscopic surgery was more effective in decreasing pain and conserving forward flexion of the shoulder than open surgery. Postoperative instability appeared to be related with generalized or bilateral shoulder joint laxity. Pain during motion after the operation was more significant during a voluntary subluxator. Low clinical scores were related with the operation on the dominant side or postoperative instability.

PURPOSE: To evaluate the effects of proximal row carpectomy. MATERIALS AND METHODS: We performed a retrospective review of the cases of 14 patients who had undergone proximal row carpectomy between April 1996 and January 2006. All of the patients were men with an average age of 37.5 years (range, 25-64 years). The mean follow-up period was 59 months (range, 18-101months). Evaluation of results was based on x-ray analysis, pain relief, the ability to return to work, activity level, range of motion (ROM) and grip strength. Pain relief was classified as very satisfied, satisfied, dissatisfied and very dissatisfied. RESULTS: The subjective results of pain relief were very satisfied in 6 cases, satisfied in 7 cases, dissatisfied in 1 case. 7 cases (50%) returned to previous occupations and 11 cases (79%) had little restriction on their daily activities. The total arc was improved from average 42 degree to 59 degree. The grip strength using Jamar dynanometer was increased from average 7.8 lbs (10.5% of the unaffected side) to average 33 lbs (44% of the unaffected side). CONCLUSION: Proximal row carpectomy is an effective surgery with preserving ROM and function for patients with wrist pain and diminished function if it is done within proper indication.

Kerosene is one of the petroleum distillates with low viscosity and high volatility. Kerosene is widely used in Korean home in heating and cooking. Kerosene ingestion or aspiration is one of the most common poisonings in young children but extremely rare in adults because kerosene is not taken with the intention of committing suicide. We report four adult cases of aspiration pneumonitis by accidental aspiration of kerosene with similar clinical presentation.

Gastrointestinal stromal tumors (GIST) form a group of uncommon neoplasms originated from the pleuripotential mesenchymal cell. There is no final conclusion about accurate diagnosis and prognostic factors of GIST. Clinical presentation is not specific and intraperitoneal bleeding is a very rare complication. We report a case of a malignant GIST complicated by intraperitoneal hemorrhage, which was diagnosed by abdominal CT and EUS before operation. A subtotal gastrectomy was perfomed without complication. The patient is still alive without recurrence.

BACKGROUND: Many studies have shown that pulmonary function differs widely among race, age and geographical residency. By virtue of the improvement of nutrition and environment, the elderly population in Korea is markedly increasing and so are the ages of patients complaining respiratory symptoms. However, we do not have our own data on the pulmonary functional reserve of elderly persons in Korea. We evaluate the deterioration of pulmonary functional reserve and standardize the predictive values of pulmonary function in the elderly population. METHOD: Pulmonary function tests were conducted in 100 men and 100 women over the age of 65. We analyzed changes of FVC and FEV1 according to age and height by linear regression. We compared our new multiple linear regression equation with other equations currently used in Korea. RESULTS: In men, the mean age was 71.5±5.2(mean±SD) years and the mean height was 163.6±6.2cm. The mean FVC was 3.42±0.49ℓ and the mean FEV1, 2.72±0.40ℓ. In women, the mean age was 72.0±5.1 years and the mean height was 149.1±5.9cm. The mean FVC was 2.22±0.42ℓ and the mean FEV1, 1.83±0.34ℓ. Multiple linear regression equation using age and height as an independent factors was as follows : FVC(ℓ)=1.857-0.0356×age(year)+0.02157×height(cm) (p<0.01, R2=0.279), FEV1(ℓ)=1.340-0.02698×age(year)+0.02021×height(cm) (p<0.01, R20.255) in men, FVC(ℓ)=-0.09765-0.03332×age(year)+0.03164×height(cm) (p<0.01, R2=0.435), FEV1(ℓ)=-0.169-0.02469×age(year)+0.02539×height(cm) (p<0.01, R2=0.41) in women. CONCLUSION: We established prediction regressions for pulmonary functional tests in the elderly Korean population. We also confirmed that currently adopted equations do not exactly anticipate the expected pulmonary functional reserve in the aged person over 65 years old. We suggest that our new equations from this study should be applied to interpret the pulmonary function tests in the elderly population in Korea.

Osteoporosis is a metabolic disease that is increasing in prevalence as people live longer. Because the orthopedic surgeon is frequently the first and often the only physician to manage patients with osteoporotic hip fractures, every effort should be made to prevent future fractures. A multidisciplinary approach is essential in treatment of osteoporotic fractures. Basic treatment includes calcium and vitamin D supplementation, fall prevention, hip protection, and balance and exercise programs. Currently available pharmacologic agents are divided into antiresorptive and anabolic groups. Antiresorptive agents such as bisphosphonates limit bone resorption through inhibition of osteoclastic activity. Anabolic agents such as parathyroid hormone promote bone formation.

BACKGROUND: Recent studies and case reports have shown that recombinant factor VIIa (rFVIIa) treatment is effective for reversing coagulopathy and reducing blood transfusion requirements in trauma patients with life-threatening hemorrhage. The purpose of this study is to evaluate the effect of rFVIIa treatment on clinical outcomes and cost effectiveness in trauma patients. METHODS: Between January 2007 and December 2010, we reviewed the medical records of patients who were treated with rFVIIa (N=18) or without rFVIIa (N=36) for life-threatening hemorrhage due to multiple traumas at the Emergency Department of Pusan National University Hospital in Busan, Korea. We reviewed patient demographics, baseline characteristics, initial vital signs, laboratory test results, and number of units transfused, and then analyzed clinical outcomes and 24-hr and 30-day mortality rates. Thromboembolic events were monitored in all patients. Transfusion costs and hospital stay costs were also calculated. RESULTS: In the rFVIIa-treated group, laboratory test results and clinical outcomes improved, and the 24-hr mortality rate decreased compared to that in the untreated group; however, 30-day mortality rate did not differ between the groups. Thromboembolic events did not occur in both groups. Transfusion and hospital stay costs in the rFVIIa-treated group were cost effective; however, total treatment costs, including the cost of rFVIIa, were not cost effective. CONCLUSIONS: In our study, rFVIIa treatment was shown to be helpful as a supplementary drug to improve clinical outcomes and reduce the 24-hr mortality rate, transfusion and hospital stay costs, and transfusion requirements in trauma patients with life-threatening hemorrhage.

PURPOSE: The prevalence of Reye syndrome has decreased since late 1980's. But we report that recently there were concentrative attacks of Reye syndrome after acute enteritis during the neonatal period. METHODS: Clinical symptoms and laboratory results(quantitative organic acid analysis, routine chemistry, arterial blood gas analysis, serum ammonia) of seven patients admitted at the Samsung Medical Center, Sanggye Paik Hospital, Wonju Christian Hospital and Chuncheon Sacred Heart Hospital, referred from Jan. 2005 to Apr. 2005, were analysed retrospectively. The major clinical symptoms were derived from the patients' clinical records sended with urine samples and quantification of organic acids were done with gas chromatography and mass spectrometry. RESULTS: The mean age of seven cases is 18 days and the major preceding symptoms were gastrointestinal symptoms(vomiting, diarrhea, refusal to feeding). The major clinical symptoms were clouded conciousness, repiratory difficulty, vomiting, seizures, and diarrhea. One patient died; that patient's serum ammonia was twenty times higher than normal. CONCLUSION: The seven patients were neonates. Reye syndrome has been known to be closely related with upper respiratory infections as a preceding disease and to internal use of aspirin, but in our study, the major preceding disease of the seven cases was gastrointestinal infection and none of these used aspirin.
