Renal infiltration is common in chronic lymphocytic leukemia (CLL), but renal impairment caused by leukemic infiltration is rare. This report describes the case of a 38-year-old man with CLL who required no medical treatment for 1 year and was admitted with nonoliguric renal insufficiency (proteinuria > 2,000 mg/day). A renal biopsy subsequently revealed leukemic infiltration by CLL. Treatment with fludarabine plus cyclophosphamide resulted in the improvement of renal function. Leukemic infiltration should be considered in the differential diagnosis of a patient with CLL and impaired renal function because renal impairment often responds well to chemotherapy.

OBJECTIVE: Mesenchymal stem cells (MSCs) have shown promise in potentially repairing injured spinal cord. These and similar cell types are being tested clinically, but the understanding about delivering method and subsequent results is lacking. This study was designed to compare the MSCs engraftment results after intralesional, intracisternal, or intravenous injection in a rat with spinal cord injury (SCI). METHODS: A total of 48 male Sprague-Dawley rats (300-350 g in size) were used with 12 in each group. Allogenic MSCs were cultured from human bone marrow aspirates. The SCI was induced using an NYU (New York University) impactor and MSCs were transplanted 1 week after the SCI. Behavioral testing was performed weekly for 6 weeks. The recipients were analyzed histologically to evaluate the extent of cell delivery and survival at the injury site. RESULTS: All three experimental groups showed better behavioral recovery compared with the control group since 6 weeks after stem cell injection (p<0.05). The intracisternal injection group showed the best functional improvement (p<0.05). The intralesional injection group showed the best engraftment until 4 weeks after stem cell injection (p<0.05). A number of the injected MSCs were trapped in the spleen in the intravenous injection group. CONCLUSION: Transplantation of stem cells by a variety of routes can deliver cells with the potential to repair injured spinal cord. Intracisternal injection can easily be translated to patients after some modifications, thus accelerating clinical application of cell therapies.

PURPOSE: Standard treatment of asymptomatic spinal cord hemangioblastoma in von Hippel-Lindau (VHL) disease has yet to be established. The purpose of this study was to propose guidelines for the treatment of asymptomatic spinal cord hemangioblastomas in VHL disease. MATERIALS AND METHODS: VHL disease patients treated for spinal cord hemangioblastomas between 1999 and 2009 were included. All spinal cord hemangioblastomas were divided into three groups: Group 1, asymptomatic tumors at initial diagnosis followed with serial imaging studies; Group 2, asymptomatic tumors at initial diagnosis that were subsequently resected; and Group 3, symptomatic tumors at initial diagnosis, all of which were resected. RESULTS: We identified 24 spinal cord hemangioblastomas in 12 patients. Groups 1, 2 and 3 comprised 13, 4 and 7 tumors, respectively. Group 1 exhibited a smaller tumor volume (257.1 mm3) and syrinx size (0.8 vertebral columns) than those of Group 2 (1304.5 mm3, 3.3 vertebral columns) and Group 3 (1787.4 mm3, 6.1 vertebral columns). No difference in tumor volume or syrinx size was observed between Groups 2 and 3. Five tumors in Group 1 were resected during follow-up because symptoms had developed or the tumor had significantly grown. Finally, among 17 asymptomatic tumors at the initial diagnosis, nine tumors were resected. Only one tumor of these nine tumors resulted in neurological deficits, while five of seven symptomatic tumors caused neurological deficits. CONCLUSION: Selective resection of asymptomatic tumors before they cause neurological deficits might bring about better outcomes.

We performed combined spondylectomy for 2 patients of malignant tumors invading spinal column and chest wall. For one patient with Pancoast tumor, anterolateral thoracotomy, apical lobectomy, chest wall resection, and hemispondylectomy were performed. For another patient with solitary metastatic tumor from nasopharyngeal cancer, posterolateral thoracotomy, chest wall resection, and total en bloc spondylectomy were performed with anterior and posterior instrumentation. The tumor including invaded chest wall and spinal column werewas removed completely in both patients. No local recurrence was found at 18 months follow-up evaluation in both patients.

PURPOSE: Breast conserving surgery using mesh can effectively fill the defective space, but there is the risk of infection. METHODS: From June 2007 to August 2010, 243 patients who underwent breast conserving surgery with polyglactin 910 mesh insert for breast cancer at our institution were retrospectively studied. RESULTS: Infection occurred in 25 (10.3%) of 243 patients. When comparing the infection and non-infection groups in multivariate analysis, there was no significant difference in age, underlying disease, preoperative biopsy methods, mass location, axillary lymph node dissection, operative methods, neoadjuvant or adjuvant chemotherapy use, mass size and removed breast volume. The infection appeared more common only in patients with body mass index (BMI) greater than 25. Infection symptoms occurred, on average, 119.5 days after surgery, and the average duration of the required treatment was 34.4 days. Out of 25 patients with postoperative infection complications, 16 (64%) patients underwent incision and drainage with mesh removal, whereas the remaining 9 (36%) only required conservative treatment. CONCLUSION: During breast conserving surgery, the risk of infection is increased in patients with high BMI, and should be taken into account when considering insertion of a polyglactin 910 mesh. Patient's age, underlying disease and perioperative treatment methods were not significant risk factors for developing mesh infection. Given that most infections seem to develop symptoms one month after surgery, a long enough observation period should be initiated. Early detection and appropriate conservative treatments may effectively address infections, thus reducing the need for more invasive therapies.

PURPOSE: The purpose of this study is to evaluate the prescription of essential or futile medications for terminal cancer patients during their final admission. MATERIALS AND METHODS: We conducted a retrospective review of the medical charts of terminally ill cancer patients admitted to the Hemato-oncology Department of two teaching hospitals from March 1, 2007 to December 31, 2009. Essential medications were based on the drugs listed by the International Association for Hospice and Palliative Care, while futile medications were defined when short-term benefit to patients with respect to survival, quality of life, or symptom control was not anticipated. RESULTS: A total of 196 patients were included. Among essential medications, strong opioids were the most frequently prescribed drugs during the last admission (62.2% fentanyl, 44.3% morphine), followed by megestrol (46.0%), and metoclopramide (37.2%); 51% of gastric protectors were prescribed with potential futility. Anti-hypertensive and antiglycemic agents were administered to those who experienced arterial blood pressure below 90 mm Hg (47.3%) or presented with a single measurement of fasting glucose below 50 mg/dL (10.7%), respectively. Statins were prescribed to 6.1% (12/196) of patients, and 75% of those prescriptions were regarded as futile. CONCLUSION: Our data suggest that effective prescription of essential medications and withdrawal from futile medications should be actively reconciled for improvement of a patient's end-of-life care.

PURPOSE: Delivering bad news (DBN) to a patient or patient's family is one of the most difficult tasks for physicians. As a complicated task, DBN requires better than average communication skills. This study investigated trainee's attitude and awareness of DBN based on a self-assessment of their experiences and performance in practice. Survey subjects were also asked to assess their perception and the need for education in conducting DBN. METHODS: A survey was carried out on their experiences with DBN, how they currently deal such situations, how they perceive such situations and the need for education and training programs. A SPIKES protocol was used to assess how they currently deal with DBN. RESULTS: One hundred one residents and fellows being trained in a teaching hospital participated in the survey. Around 30% had bad experiences due to improperly delivered bad news to a patient. In terms of self-assessment of how to do DBN, over 80% of trainees assessed that they were doing DBN properly to patients, using a SPIKE protocol. As for how they perceived DBN, 90% of trainees felt more than the average level of stress when they do DBN. About 80% of trainees believed that education and training is much needed during their residency program for adequate skill development regarding DBN. CONCLUSION: We suggest that education and training on DBN may be needed for trainees during the residency program, so that they could avoid unnecessary conflict with patients and reduce stress from DBN.

We report a series of epidural hematomas which cause neurologic deterioration after spinal surgery, and have taken risk factors and prognostic factors into consideration. We retrospectively reviewed the database of 3720 cases of spine operation in a single institute over 7 years (1998 April-2005 July). Nine patients who demonstrated neurologic deterioration after surgery and required surgical decompression were identified. Factors postulated to increase the postoperative epidural hematoma and to improve neurologic outcome were investigated. The incidence of postoperative epidural hematoma was 0.24%. Operation sites were cervical 3 cases, thoracic 2 cases, and lumbar 4 cases. Their original diagnoses were tumor 3 cases, cervical stenosis 2 cases, lumbar stenosis 3 cases and herniated lumbar disc 1case. The symptoms of epidural hematomas were neurologic deterioration and pain. After decompression, clinical outcome revealed complete recovery in 3 cases (33.3%), incomplete recovery in 5 cases (55.6%) and no change in 1 case (11.1%). Factors increasing the risk of postoperative epidural hematoma were coagulopathy from medical illness or anticoagulation therapy (4 cases, 44.4%) and highly vascularized tumor (3 cases, 33.3%). The time interval to evacuation of complete recovery group (29.3 hours) was shorter than incomplete recovery group (66.3 hours). Patients with coagulopathy and highly vascularized tumor were more vulnerable to spinal epidural hematoma. The postoperative outcome was related to the preoperative neurological deficit and the time interval to the decompression.
