We report an extremely rare case of a diffuse hepatic hemangiomatosis without extrahepatic involvement in an adult. The imaging findings of this tumor were similar to those of a hepatic hemangioma and included contrast enhancement with a centripetal filling pattern of the entire hepatic tumor on the delayed phase of a dynamic CT and inhomogeneous diffuse uptake of the entire tumor on blood-pool images obtained five hours later on a 99mTc-labeled red blood cell scan. Despite its rarity, diffuse hepatic hemangiomatosis can be suggested in adult patients with diffusely involved hepatic tumors showing the radiological findings of a hepatic hemangioma.

Marchiafava-Bignami disease (MBD) is a fatal disorder characterized by demyelination of the corpus callosum. MRI, suggestive of corpus callosum demyelination with associated white matter involvement in both cerebral hemispheres, indicates a diagnosis of MBD. In this case, MR diffusion-weighted findings taken at an acute stage of MBD revealed lesions not only in the corpus callosum but also in the cerebral cortex. Lower apparent diffusion coefficient values of the corpus callosum and cortical lesions were associated with poor clinical outcome.

Preoperative prediction of patellar tendon length is important during anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone (BPTB) autograft. Three methods of imaging analysis to predict patellar tendon length were compared in this study. One hundred and twenty-three patients who underwent ACL reconstruction using BPTB autograft by single surgeon during October 2002 through April 2011 were included. We measured the patellar tendon length from true and oblique lateral simple radiographs (classified according to degree of rotation) and magnetic resonance image (MRI). These values were compared with actual length measured during operation and assessed accuracy by calculating the coefficient of determination. The mean length of patellar tendon measured during operation and by true lateral and oblique lateral radiographs and MRI were 42.4+/-0.45 mm (range, 32.0-54.0 mm), 41.7+/-0.61 mm (range, 24.2-55.3 mm), 40.7+/-0.57 mm (range, 24.8-51.5 mm), and 41.7+/-0.52 mm (range, 28.7-56.0 mm), respectively. The correlation of patellar tendon length was the most strong between actual length and value from true lateral radiograph (coefficient of determination, r2=0.660) according to simple linear regression analysis. R2 values were 0.361 and 0.332 for oblique lateral radiograph and MRI compared to actual value, respectively. In conclusion, Patellar tendon length measured on true lateral radiograph was the best method to coincide with actual patellar tendon length among various preoperative prediction methods.

BACKGROUND: To report the results of an arthroscopic percutaneous repair technique for partial-thickness tears of the anterosuperior cuff combined with a biceps lesion. METHODS: The inclusion criteria were evidence of the upper subscapularis tendon tear and an articular side partial-thickness tear of the supraspinatus tendon, degeneration of the biceps long head or degenerative superior labrum anterior-posterior, above lesions treated by arthroscopic percutaneous repair, and follow-up duration > 24 months after the operation. American Shoulder and Elbow Surgeons (ASES) score, constant score, the pain level on a visual analogue scale, ranges of motion and strength were assessed. RESULTS: The mean (+/- standard deviation) age of the 20 enrolled patients was 56.0 +/- 7.7 years. The forward flexion strength increased from 26.3 +/- 6.7 Nm preoperatively to 38.9 +/- 5.1 Nm at final follow-up. External and internal rotation strength was also significantly increased (14.2 +/- 1.7 to 19.1 +/- 3.03 Nm, 12.3 +/- 3.2 to 18.1 +/- 2.8 Nm, respectively). Significant improvement was observed in ASES and constant scores at 3 months, 1 year and the time of final follow-up when compared with preoperative scores (p < 0.001). The mean subjective shoulder value was 86% (range, 78% to 97%). CONCLUSIONS: The implementation of complete rotator cuff repair with concomitant tenodesis of the biceps long head using arthroscopic percutaneous repair achieved full recovery of normal rotator cuff function, maximum therapeutic efficacy, and patient satisfaction.

PURPOSE: To evaluate the effects of autologous tumor vaccine alone or in combination with dendritic cell vaccines, as a method of stimulating antigen-presenting cells in patients with a locoregionally confined renal cell carcinoma (RCC) or metastatic disease. MATERIALS AND METHODS: Twenty-seven patients with RCC pathological stages II to IV were treated with autologous tumor cell vaccine, either with or without dendritic cell vaccine. Interleukin 2 (IL-2) based immunotherapy was also applied to the patients with metastatic disease. Immunomagnetic beads were used to isolate CD14+ monocytes from patient or donor in dendritic cell preparations. IL-4 and granulocyte-macrophage colony stimulating factor (GM-CSF) were used for maturation of dendritic cells. Flow cytometry evaluations were performed for dendritic cell maturation and changes in the immunological profiles following our treatment. RESULTS: Both the isolation of CD14+ monocyte, using Immunomagnetic beads, and the maturation of dendritic cells, using IL-4 and GM-CSF stimulation, were effective. Tumor immunological profiles showed increased CD3 and CD56 populations after treatment. Side effects related with vaccine were minimal and tolerable. Patients were stratified by the purpose for the vaccination; 8 patients for post-nephrectomy adjuvant therapy and 19 for adjuvant immunotherapy of a metastatic disease. All 8 patients in the former showed a disease free state, while only one of the 19 in the latter group remained in complete remission, while 6 showed short-term responses. CONCLISIONS: Autologous RCC vaccine, combined with or without dendritic cell vaccine, might be effective in the suppression of tumor recurrence in locoregionally confined RCC, although a longer follow-up will be required. These vaccines should be further developed to reach their therapeutic purpose in metastatic RCC.

BACKGROUND: There are epidemiological clinical studies that describe the relationship of decreased serum cholesterol levels or their treatment with suicides, offensive actions and depression. METHODS: We studied 140 patients who were hospitalized at Asan Foundation Jeongup Hospital (in Korea) via emergency room after suicide attempts and whose serum cholesterol levels were acquired during 53 months (from Jan. 1. 1995 to May 31. 1999). They were evaluated with the use of t-test. The serum cholesterol levels were compared between the control group of 140 persons who underwent health check ups and 140 patients who were of similar age and sex ratios. RESULTS: Subjects showed significant decrease in serum cholesterol levels in comparison with the control group. Low serum cholesterol levels were related with the severity of suicidal attempts. 1) The subjects showed lower serum cholesterol levels than the control group(150.51+/-56.69mg/dl vs 185.61+/-31.94mg/dl; t= 6.382, df=278, P<0.001) (Table 3). 2) Those who killed themselves showed statistically significant decrease in serum cholesterol levels than those who survived after their suicidal attempts(169.13+/-49.29mg/dl vs 135.89+/-34.14; t=2.005, P<0.05) (Table 4). CONCLUSION: This study was carried out in farming and fishing villages of Korea. The result showed that the decrease in serum cholesterol levels increased the risk of suicide trials. This fact is similar to the results of the previous studies performed at other farming and fishing communities. In addition, those who killed themselves had lower serum cholesterol levels compared to those who survived suicide attempts. This relationship was associated with depression.

PURPOSE: The aim of this study was to compare the drainage amount, total blood loss, and clinical results between two different positions of suction drainage after total knee arthroplasty. MATERIALS AND METHODS: A total of 100 patients who underwent one stage bilateral total knee arthroplasty were enrolled. In experiment 1 with 50 patients, we compared the drainage amount, pain, range of motion, and complications of the leg whose suction drain was inserted into the joint cavity with those of the contralateral leg whose suction drain was inserted in subcutaneous tissue. Another 50 patients of experiment 2 had suction drainage in the joint cavity of both legs and the total blood loss (sum of drainage output, exudates, and hematoma of subcutaneous tissue and joint) was calculated and compared with that of experiment 1. RESULTS: In experiment 1, the drainage amount was less in the leg with suction drainage in subcutaneous tissue compared with the contralateral leg with suction drainage in the joint cavity (p<0.001). However, the postoperative joint pain was significantly different only on post-operative day 2 between two legs. In experiment 2, there was no significant difference in the total blood loss between the two groups. CONCLUSION: Although the drainage amount was less in the leg whose suction drain was kept in subcutaneous tissue compared with the contralateral leg whose suction drain was in the joint cavity, the total blood loss and the clinical results were not significantly different according to the position of the suction drain. Therefore, we can conclude that the subcutaneous position of the suction drain did not yield superior results.

PURPOSE: The purpose of this study is to evaluate the risk of sequential bilateral total knee arthroplasty (TKA) under 1 anesthesia in patients 75 years or older. MATERIALS AND METHODS: Patients aged 75 years or older who underwent sequential bilateral TKA (bilateral group, n=159) and unilateral TKA (unilateral group, n=159) between 2002 and 2012 were selected. All patients were evaluated for underlying medical diseases, such as cardiac, pulmonary, and renal problems, and high-risk patients were recommended to postpone the surgery. We compared the underlying diseases, major postoperative complications, and the length of hospital stay between bilateral and unilateral groups. RESULTS: The prevalence of underlying diseases of the bilateral group was 74.8% and major complications occurred in 6 patients (3.8%). The prevalence of underlying diseases of the unilateral group was 52.4% and complications were observed in 4 patients (2.4%). Although the complication rate of the bilateral group was slightly higher than that of the unilateral group, the difference was not statistically meaningful (p=0.204). The length of hospital stay was 21.9 days for the bilateral group and 24.9 days for the unilateral group. CONCLUSIONS: There was no significant difference in postoperative complications between groups. The result shows that bilateral TKA can be relatively safe compared with unilateral TKA in patients 75 years or older. However, careful selection of low-risk patients is advised.

Because a cavitary pulmonary metastasis is rare, it may not be readily identified. However, various types of cancers can metastasize to the lung in the form of cavities. We report a case of a multiple cavitary metastases to the lung from a cholangiocarcinoma in a 60-year-old man. He complained of generalized weakness and a poor oral intake for 2 months. The plain chest radiography and the chest computed tomography showed multiple small thick-walled cavities and nodules the both lungs. A bronchoscopic examination revealed a focal irregularly elevated surface of the mucosa at the orifice of the superior segment of the right lower lobe and the biopsy demonstrated an infiltrative metastatic adenocarcinoma. The abdomen-pelvis computed tomography showed an ill-marginated and irregularly low-dense area in the right lobe of the liver and a diffuse dilatation of the peripheral intrahepatic bile ducts. The esophagogastroscopy and colonoscopy showed no abnormal findings. It was concluded that the cholangiocarcinoma of the liver metastasized to the lung in the form of cavities. Thereafter, the patient underwent six cycles of the systemic chemotherapy with gemcitabine and cisplatin, and the follow-up imaging studies showed a partial response.
