PURPOSE: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. MATERIALS AND METHODS: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (> or =3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. RESULTS: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was 10.7degrees, 13.8degrees, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. CONCLUSION: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

Attempts were made to isolate and identify Korean bovine Babesia parasite. Blood samples were collected from Holstein cows in Korea, and Babesia parasites were propagated in SCID mice with circulating bovine red blood cells for isolation. The isolate was then antigenically and genotypically compared with several Japanese isolates. The Korean parasite was found to be nearly identical to the Oshima strain isolated from Japanese cattle, which was recently designated as Babesia ovata oshimensis n. var. Haemaphysalis longicornis was the most probable tick species that transmited the parasite.

OBJECTIVE: The authors demonstrate neuroprotective effects of antioxidant in reperfusion injury using ischemic rat model and evaluate the clinical eligibility of this agent to ischemic cerebrovascular diseases. METHODS: Rat model was made according to Longa method. Thirty-six Sprague-Dawley rats were used and were equally divided into three groups;A) treated subcutaneously with D,L-6,8-Thioctic acid 30 minutes before occlusion, B) within one hour after occlusion, and C) with vehicle only. Neurologic examination was performed immediately and 24 hours after reperfusion. Twenty-four hours after reperfusion, brains were extracted and stained with 2% 2,3,5-Triphenyltetrazolim chloride in 2mm-thickness section. Then, fixed sections were digitalized and used for infarct area calculation. RESULTS: There was no significant statistical difference in recorded hemodynamic and physiologic parameters between three groups. The neurologic status taken immediately following reperfusion were A) 2.67+/-0.492, B) 2.75+/-0.452, and C) 2.83+/-0.389, and were improved to A) 1.67+/-0.898, B) 1.92+/-0.900, and C) 2.08+/-0.793 just before sacrificing. However, there was no statistically significant difference between three groups. Mean volume of cerebral infarction was A) 9.5+/-1.67%, B) 10.4+/-1.58%, and C) 11.3+/-1.12% with no significant difference. Any specific correlation between the neurologic status and the mean infarction volume was not observed. CONCLUSION: Any single agent does not seem to reduce the infarction volume holistically, therefore, the incoming therapeutic target should be the development of versatile neuroprotective agents or the selection of preexisting synergistic compounds without compromising patients' safety.

In order to study the range of flight and feeding activity of Anopheles sinensis, the dispersal experiment was conducted in Paju city, located in the northern part of Gyeonggi-do, Republic of Korea, during the period of 7th to 28th September 1998. Unfed females An. sinensis were collected in cowshed and released after being marked with fluorescent dye at 23:00 hours on the same day. Released female mosquitoes were recaptured everyday during 21 days using light traps, which were set at 10 sites in the cowsheds located 1, 3, 6, 9 and 12 km north-northwest and north-northeast and at 3 sites located 1, 6 and 9 km toward south-west from the release point. In addition, to study the longest flight distance in one night, we set the light traps at 16 and 20 km toward north-northeast from the release site. All the collected mosquitoes were placed on filter papers and observed on UV transilluminator after treatment with one drop of 100% ethanol. Out of 12,773 females of An. sinensis released, 194 marked females mosquitoes were recaptured, giving 1.52% recapture rate. Of 194, 72 mosquitoes (37.1%) were recaptured in light traps from three places set at 1 km from the release point, 57 mosquitoes (29.4%) from two places at 1-3 km, 41 mosquitoes (21.1%) from three places at 3-6 km, 20 mosquitoes (10.3%) from three places at 6-9 km, and 4 mosquitoes (2.1%) from two places at 9-12 km. Since 170 female mosquitoes (87.6%) out of 194 marked mosquitoes were captured within 6 km from the release point, this flight radius represents the main activity area. An sinensis was found to be able to fly at least 12 km during one night.

BACKGROUND: The patients with mitral stenosis are generally accompanied with impaired pulmonary function. The aim of this study was to evaluate the changes of pulmonary function after percutaneous mitral balloon valvuloplasty (PMV) in that patients. METHODS: PMV was performed in 36 patients with mitral stenosis in Pusan National University Hospital and hemodynamic, echocardiographic and pulmonary function test data before and after PMV were analyzed. RESULT: After PMV, NYHA functional class was improved from 2.2+/-0.6 to 1.2+/-0.4 (p<0.001). The mean left atrial pressure and mean pulmonary arterial pressure significantly decreased from 14.5+/-6.2 mmHg to 5.7+/-4.4 mmHg(p<0.001) and from 25.3+/-10.9 mmHg to 15.5+/-7.4 mmHg (p<0.001), respectively. Cardiac output was slightly decreased from 5.34+/-1.31 L/min to 5.28+/-1.25 L/min (p=0.50). Mean mitral pressure gradient decreased from 13.5+/-5.8 mmHg to 4.4+/-2.1 mmHg (p<0.001) and mitral valvular area significantly increased from 0.86+/-0.19 cm2 to 1.71+/-0.28 cm2 (p<0.001). In pulmonary function test, only MVV and PEF was significantly improved from 77.2+/-23.8% to 88.4+/-27.9% (p<0.01) and 87.1+/-26.8% to 97.5+/-26.4% (p<0.01), respectively. But, VC, FEV1, FEF25-75% and FVC were not changed significantly. In exercise treadmil test, exercise duration was significantly improved from 482.0+/-266.2 sec to 718.0+/-287.5 sec (p<0.001). CONCLUSION: We observed the results of better hemodynamic changes and exercise capacity after PMV. But, there was no significant improvement in pulmonary function after PMV. In our opinion, irreversible pulmonary changes and hemodynamic effect on pulmonary function should be considered.

BACKGROUND: The aims of this study were to assess the etiologies, survival and prognositic factors of patients with chronic cor pulmonale visited Pusan National University Hospital. METHODS: This study included 103 patients with chronic cor pulmonale. There were 67 men and 36 women. The diagnosis of chronic cor pulmonale was primarily based on the presence of underlying lung disorder and echocardiographic finding of enlarged or hypertrophied right ventricle. Other clinical data including patients' symptoms and signs, findings of arterial blood gas analysis, hematologic and biochemical laboratory and pulmonary function test were assessed. RESULTS: The most common underlying lung disorder was pulmonary tuberculosis (59.2%) and chronic obstructive pulmonary disease was the next (28.2%). The survival rate was 57% in one year, 45% in two years, and 34% in three years. The prognostic factors were maximal voluntary ventilation(MVV), forced vital capacity(FVC), FEV1, serum Na, vital capacity(VC), serum albumin and peak expiratory flow(PEF) in univariate analysis. And in multivariate analysis, serum albumin(p=0.0144) and VC(p=0.0078) were statistically significant. CONCLUSION: Pulmonary tuberculosis was the most important underlying lung disorder in chronic cor pulmonale. The survival rate was 57% in one year, 45% in two years, and 34% in three years. Serum albumin(p=0.0144) and VC(p=0.0078) were statistically significant prognostic factors.

Skeletal muscle metastasis of gastric cancer is extremely rare and is associated with various symptoms. Here, we report on a 60-year-old woman with right hip pain after excessive walking. Two years earlier, the patient had been treated for advanced gastric cancer (surgery, adjuvant chemotherapy). Upon magnetic resonance imaging, diffuse muscle swelling and high signal intensity were observed in T2-weighted images of the right hip muscle. However, the FDG uptake in the right gluteal muscles was not obviously increased. Pathological examination of muscle biopsy revealed metastatic adenocarcinoma of stomach origin. The patient was treated with chemotherapy, and the swelling and pain in the right hip are progressively improving.

PURPOSE: The aim of this study was to evaluate long-term oncologic outcomes after concurrent chemoradiation treatment for anal cancer. MATERIALS AND METHODS: Between January 1979 and December 2008, the records of 50 consecutive patients with anal cancer and who were treated by chemoradiation or radiation only with a curative intent were retrospectively reviewed. The oncologic outcomes and the risk factors for recurrence were analyzed. RESULTS: Of the 50 patients, 49 underwent concurrent chemoradiation and one underwent radiation only. After these definitive treatments, 43 (86.0%) achieved a clinical complete response. During the median follow-up of 60 months (range: 2-202 months), the 5-year overall survival, disease-free survival, and locoregional recurrence-free survival were 84.2%, 72.7%, and 69.9%, respectively. Multivariate analysis revealed that the performance status (p=0.031) and a clinical complete response (p=0.039) were the independent predictors for overall survival; lymph node involvement (p=0.031) was the only independent predictor for disease-free survival. CONCLUSION: The performance status and a clinical complete response may be reliable predictors of survival after chemoradiation for anal cancer. The addition of irradiation to the inguinal area may not be significantly associated with the outcomes.

PURPOSE: The aim of this study was to evaluate the efficacy and tolerability of the oxaliplatin, 5-fluorouracil (5-FU) and low dose leucovorin (LV) combination in patients with advanced colorectal cancer. MATERIALS AND METHODS: Patients with unresectable or recurrent colorectal carcinomas were prospectively accrued. Up to one prior chemotherapy regimen was allowed. Patients received oxaliplatin, 85 mg/m2, administered as a 2-hour infusion on day 1, followed by LV, 20 mg/m2, as a bolus and 5-FU, 1, 500 mg/m2, via continuous infusion for 24 hours on days 1 and 2. Treatment was repeated every 2 weeks until disease progression or adverse effects prohibited further therapy. RESULTS: Between August 1999 and May 2004, 31 patients were enrolled in this study. Of the patients enrolled, 24 and 31 were evaluable for tumor response and survival analysis, respectively. The patients' characteristics included a median age of 59, with 6 (19%) having had prior chemotherapy. No patient achieved a complete response, but nine (38%) attained a partial response. Seven (29%) patients maintained a stable disease and 8 (33%) experienced increasing disease. The median duration of the response was 6 months. After a median follow-up of 9.6 months, the median time to progression was 3.8 months, with a median survival of 10.7 months. The hematological toxicities were mild to moderate, with no treatment-related mortality or infection. The major non-hematological toxicity was gastrointestinal toxicity. CONCLUSIONS: The combination chemotherapy of oxaliplatin, low dose LV and continuous infusion of 5-FU is safe and has a cost-benefit, but is a moderately effective regimen in advanced colorectal cancer. A randomized trial comparing low and high dosages of leucovorin in the FOLFOX regimen is warranted.
