Avascular osteonecrosis has frequently occured in patients who have undergone transplantation of a kidney and generally has been considered to be a complication of the use of corticosteroids. But there are controversies regarding their dosage and duration of use in its influence on prevalence of avascular osteonecrosis. We analyzed the cases of our patients who underwent transplantation of a kidney and who we were able to follow up more than 8 months. l. Of a total of 300 patients, osteonecrosis developed in 24 joints of 12 patients. 2. Osteonecrosis was more frequently found in group of patients who were administered with larger doses of steroid. 3. Rejections of the transplanted kidney occured more frequently in those groups with osteonecrosis. 4. Most of rejections occured within 3 months after renal transplantation. 5. It took 4–26 months (average 12.3 months) the osteonecrosis could be found. 6. There were no differences in blood concentration of calcium phosphate and creatinine between osteonecrosis and non-osteonecrosis group. 7. Replacement arthroplasties were done in 10 joints without significant complication.

Herein, we report a 36-year-old Asian male patient who presented with grouped multiple erythematous waxy papules and nodules on his right medial thigh. He had undergone amputation of the right second toe because of a stage IIa malignant melanoma, 3 years previously. At the time of surgery for the primary tumor, right inguinal lymph node dissection revealed no nodal involvement. Three years after the diagnosis of the primary tumor, crops of multiple erythematous papules and nodules developed. Initial histopathologic evaluation of the papules showed nests of small epithelioid cells similar to compound nevi. However, cytologic features, including high mitotic figures, lack of maturation, and some hyperchromatic nuclei suggested metastatic melanoma. In addition to the pathologic findings, the tumors were on the right thigh, which was the same side as the primary malignant melanoma. The patient underwent wide excision of the tumor and split-thickness skin grafting.

OBJECTIVES: Deficit schizophrenia (DS) constitutes a disease separate from non-deficit schizophrenia (NDS). The aim of the current study was to compare the quantitative EEG and low resolution electromagnetic tomography (LORETA) imaging between DS and NDS. METHODS: This study was performed by 32 channels EEG for 42 schizophrenia patients who we categorized into DS and NDS using proxy instrument deficit syndrome (PDS). We performed the absolute power spectral analyses for delta, theta, alpha, low beta and high beta activities. We compared power spectrum between two groups using Independent t-test. Partial correlation test was performed with clinical parameters. Standardized LORETA (sLORETA) was used for comparison of cortical activity, and statistical nonparametric mapping (SnPM) was applied for the statistical analysis. RESULTS: DS showed significantly increased delta and theta absolute power in fontal and parietal region compared with NDS (p<0.05). Power spectrum showed significant correlation with 'anergia' and 'hostility/suspiciousness' subscale of brief psychiatric rating scale (BPRS)(p<0.05). sLORETA found out the source region (anterior cingulate cortex/limbic part) that delta activity was significantly increased in DS (p=0.042). CONCLUSIONS: DS showed different cortical activity compared with NDS. Our results may suggest QEEG and LORETA could be the marker in differentiating between DS and NDS.

OBJECTIVES: Supraorbital route through eyebrow incision, mini-pterional craniotomy, and midline interhemispheric route are most generally used methods for key hole surgery on anterior circulation aneurysm. Surgical route is determined according to aneurysm architecture and patient status. The approaching route can be selected according to the findings of 3-dimensional computed tomography (CT) angiography simulation. Prospective decision-making protocol, surgical technique of key hole surgery, and the results are presented in this paper. METHODS: 173 patients with anterior circulation aneurysms were treated by direct surgical neck clipping during last two years. Twenty patients of poor grade (Hunt-Hess grade IV,V) were treated by craniectomy with clipping. Decision making protocol was applied to 153 unruptured and good grade ruptured aneurysm patients. Simulation of key hole surgery was conducted by CT work station using conventional software InSpace (Siemens, Germany), and direction and shape of aneurysm was observed from the perspective of microsurgery. RESULTS: 113 ruptured and 40 unruptured aneurysms were secured through one of the three approaching routes. Supraorbital approach had been performed in 82 cases (unruptured 24, ruptured 58) while 64 cases were treated by mini-pterional craniotomy. Midline key hole surgery were carried out in seven distal anterior circulation aneurysms (DACA) using brain navigation system. After locating the aneurysm, supraorbital approach was applied to 46 cases involving anterior cerebral artery (ACA), 16 in internal carotid artery (ICA) and 20 in middle cerebral artery (MCA). Mini-pterional craniotomy was carried out in aneurysms located in ACA (9), ICA (18), and MCA (37). In most cases, the results of clipping were good. The average follow-up time was 16.7months (ranging 2 to 32months) and the results were cosmetically excellent. CONCLUSION: Simulating surgical approaches with 3-D CT angiography is a highly useful method for determining various surgical routes in anterior circulation aneurysm treatment. Therefore, minimally invasive and tailored surgical approaches are recommended since optimal route can be found through simulation. Thus, minimal invasive and tailored surgical approach is available through this method. These procedures have clear advantages; shorter surgical time and hospital stay, less operative trauma, reduced costs and less pain, and better cosmetic outcomes compared to standard craniotomy. Optimal surgical results are expected from minimally invasive and tailored surgical craniotomy.

OBJECTIVE: We performed the surgery using titanium double cylindrical cage for anterior cervical discectomy and interbody fusion in various degenerative cervical diseases. We compared the clinical results and radiologic results in cervical anterior disectomy. Method: From October 2007 to October 2008, 19 patients diagnosed with degenerative disease underwent anterior cervical disectomy and interbody fusion. The postsurgical clinical results were analyzed retrospectively by classifying them into four levels based on Odom's criteria(excellent, good, fair, and poor) after a more than 6-month follow-up period. RESULTS: In all cases, a single segment was involved, and surgery was performed for 19 segments. The C5-C6 inter-vertebral disc was the most commonly affected(9 cases). The clinical outcome was excellent, good, and fair in 5(26.3 %), 10(52.6%), and 4(21.0%) cases, respectively. An excellent or good outcome was considered as a successful result, showing an approximately 78.9% cure rate. No patient had aggravated symptoms compared with their preoperative status. CONCLUSION: Relatively satisfactory clinical and radiographic results were obtained with double cylindrical cages. The surgical method is relatively simple, allows good synostosis, and prevents many complications associated with autografting. It is also less traumatic to the spinal cord during cage insertion. Therefore, double cylindrical cages are generally more recommended for treating cervical spondylosis accompanied with flat cages.

PURPOSE: This study evaluated the preoperative and postoperative radiologic findings of patients with complete repairs after massive rotator cuff tears along with the incidence of re-tear and the clinical outcomes. MATERIALS AND METHODS: This study evaluated 33 cases who had open complete repairs for massive rotator cuff tears and these patients were followed up for more than 24 months. The clinical evaluation was performed according to the shoulder joint function test of the American Shoulder and Elbow Surgeons (ASES), and the degree of arthritis related to the massive rotator cuff tears was evaluated using the Hamada classification. RESULTS: The ASES scores improved from 37.6 preoperatively to 85.6 postoperatively. The mean preoperative acromio-humeral interval (AHI) score was 6.5 mm, which increased to 9.3 mm immediately after surgery, and there was a decreased to 6.5 mm noted at the last follow up. The lower radiology stages of arthritis according to the classification showed better preoperative and postoperative results. CONCLUSION: An open complete repair as the surgical treatment for a massive rotator cuff tear showed satisfactory results for pain relief and an improvement in the shoulder joint function though re-tear after surgery.

PURPOSE: Glomus tumor has known as smaller than 1 cm, hard to palpate, therefore patients often suffer from chronic pain. Based on our experiences about glomus tumors, we would like to evaluate their distributions. MATERIALS AND METHODS: This study includes 24 cases that underwent surgery for clinically diagnosed glomus tumor from January, 2001 to May, 2009. Clinical symptoms were firstly evaluated and ultrasonography in 8 cases and Magnetic Resonance Imaging (MRI) in 5 cases were performed for more accurate diagnosis and localization. Complete resection with biopsy was done in all cases. RESULTS: According to pathologic findings, 20 out of 24 cases were reported as glomus tumor, and the other 4 cases were 2 fibrous tumor with chronic inflammation, 1 hemangioma, and 1 neuroma. Twenty glomus tumors at dorsal side under the nail were distributed to proximal radial in 11 cases, proximal ulnar in 6 cases, distal radial in 2 cases and distal ulnar in 1 case. Tumors were more frequently found at proximal in 17 cases(85%) and at radial side in 13 cases(65%). CONCLUSIONS: Glomus tumors tend to occur under nail of proximal and radial part. We think that accurate diagnosis and location of glomus tumors are needed to complete surgical resection.
