Background:
Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined.
Methods:
This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months.
Conclusion
This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Cell therapeutic agents for treating degenerative brain diseases using neural stem cells are actively being developed. However, few systems have been developed to monitor in real time whether the transplanted neural stem cells are actually differentiated into neurons. Therefore, it is necessary to develop a technology capable of specifically monitoring neuronal differentiation in vivo. In this study, we established a system that expresses cell membrane-targeting red fluorescent protein under control of the Synapsin promoter in order to specifically monitor differentiation from neural stem cells into neurons. In order to overcome the weak expression level of the tissue-specific promoter system, the partial 5′ UTR sequence of Creb was added for efficient expression of the cell surface-specific antigen. This system was able to track functional neuronal differentiation of neural stem cells transplanted in vivo, which will help improve stem cell therapies.

A 38-year-old male-to-female transgender patient who had undergone a transsexual operation 20 years earlier presented with right flank pain and chills. Abdominal CT scan and gastrografin colon enema revealed a right psoas abscess and an abnormal communication between the large bowel and this psoas abscess. She underwent a right hemicolectomy and was finally diagnosed as having a Klebsiella psoas abscess due to perforated diverticulitis and intestinal tuberculosis. Additional antibiotics and antituberculous medication were required. A secondary psoas abscess due to diverticulitis is rare, and to our knowledge, no case combined with intestinal tuberculosis has previously been reported. We present the case with a brief review of related reports.

PURPOSE: Advanced techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue more safely with minimum blood loss. However, few have analyzed the metabolic consequences of liposuction. The purpose of this study was to identify the early effects of the surgical removal of subcutaneous fat on metabolic changes in patients who have undergone liposuction. METHODS: Nineteen patients were evaluated from June 2005 to December 2005. Preoperative body weight, serums levels of lipids, apolipoprotein A1, dehydroepiandrosterone(DHEA), uric acid, insulin, and glucose were evaluated. Insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR), which is based on fasting glucose and insulin concentrations. All of these data were remeasured in 1 and 4 weeks postoperatively. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a Liposlim(R) power-assisted unit. RESULTS: Average volumes of infiltrate and aspirate were 3,268mL and 2,892mL, respectively. Results in 1 week postoperatively demonstrated a significant difference in high-density lipoprotein(HDL) cholesterol, apolipoprotein A1, insulin, and HOMA-IR levels. However, all values were within normal limits and returned to baseline in 4 weeks postoperatively. CONCLUSION: This study provides little to support the presumed therapeutic effect of liposuction. And, it is unclear whether liposuction can prevent or be used to treat the metabolic complications of obesity. However, the results of the present study lead us to believe that liposuction is a metabolically safe procedure.

OBJECTIVE: This study is designed to elucidate the requirements for angiographic evaluation and the selection of appropriate therapeutic approaches in patients who had strongly suggestive traumatic carotid arterial lesions. METHODS: Ten cases of traumatic internal carotid arterial lesions were analysed in this study. Injury mechanisms, neurological status, computed tomography scans, pre-and postoperative angiograms, and methods and results of the treatment were included. RESULTS: Of 10 cases, carotid-cavernous fistula(CCF) alone in three, CCF with intracranial pseudoaneurysms in three, pseudoaneurysm with dissection in one, extracranial internal carotid artery thrombosis in one, extracranial pseudoaneurysm in one, and the remaining one had all of the CCF, intracranial pseudoaneurysm and dissection. Seven of these 10 cases had sphenoid sinus wall fractures and six had subarachnoid hemorrhage. Six cases were treated with endovascular techniques, and four with direct parent artery occlusion and bypass surgery. No postoperative morbidity or additional permanent neurological deficits occurred except one patient who suffered from reperfusion hemorrhage after bypass surgery. CONCLUSION: Head trauma patients with facial bone fractures and thick subarachnoid hemorrhage should be evaluated for the development of traumatic injuries to the carotid artery as soon as possible. Endovascular treatment to these lesions have come to play an increasing role. Patients with traumatic internal carotid artery lesions who do not tolerate test occlusion require extracranial to intracranial bypass surgery before occlusion.

OBJECTIVE: The objective of this study was to determine the photodynamic therapeutic response of U-87 human glioma cell in vitro as well as in the nude rat xenograft model using photofrin as photosensitizer. MATERIAL AND METHOD: U-87 cells were cultured on 96-well culture plates, photofrin(Quadralogic Technologies Inc., Vancouver, Canada) was added into the cell culture medium at concentration of 1ng/ml, 2.5ng/ml, 5ng/ml, 10ng/ml and 20ng/ml. 24 hour after drug treatment, cells were treated with optical(632nm) irradiation of 100mJ/cm2, 200mJ/cm2 and 400mJ/cm2. Photofrin(12.5mg/kg, i.p.) was administered to 28 nude rats containing intracerebral U-87 human glioma as well as 26 normal nude rats. 48 hours after administration, animals were treated with optical irradiation(632nm) of 35J/cm2, 140J/cm2 and 280J/cm2 to exposed tumor and normal brain. The photofrin concen-tration was measured in tumor and normal brain in a separate population of animals. RESULTS: By MTT assay, there was 100% cytotoxicity at any dose of photofrin with optical irradiation of 200mJ/cm2 and 400mJ/cm2. But at the optical irradiation of 100mJ/cm2 cells were killed in dose dependent manner 28.5%, 49.1%, 54.4%, 78.2%, and 84.6% at concentration of 1ng/ml, 2.5ng/ml, 5ng/ml, 10ng/ml and 20ng/ml, respectively. Dose dependent PDT lesions in both tumor and normal brain were observed. In the tumor lesion, only superficial tissue damage was found with optical irradiation of 35J/cm2. However, in the optical irradiation group of 140J/cm2 and 280J/cm2 the volume of lesions was measured of 7.2mm3 and 14.0mm3 for treatment at 140J/cm2 and 280J/cm2, respectively. The U-87 bearing rats showed a photofrin concentration in tumor tissue of 6.53+/-2.16ng/g, 23 times higher than that found in the contralateral hemisphere of 0.28+/-0.15ng/g. CONCLUSION: Our data indicate that the U-87 human glioma in vitro and in the xenografted rats is responsive to PDT. At these doses, a reproducible injury can be delivered to human glioma in this model. Strategies to spare the normal brain collateral damage are being studied.

OBJECTIVES: For Parkinsonian patients who had not reacted favorably on drug therapy are good candidate for ventroposterolateral pallidotomy, although not curative. We studied these patients after unilateral pallidotomy, to confirm the effectiveness and safety of this procedure. METHODS: We evaluated the 17 patients with idiopathic Parkinson's diesease who had undergone unilateral posteroventral pallidotomy. All patients responded to levodopa initially. Mean age was 55 years(38-75years), and mean duration of disease was 9.8 years(3-20years). Pre-and postoperative evaluation at 3 month intervals included Unified Parkinson's Disease Rating scale(UPDRS) scoring, Hoehn and Yahr(H and Y) staging, and neuropsychological examinations. RESULTS: Pallidotomy significantly improved parkinsonian symptom(tremor, rigidity, bradykinesia, dyskinesia, sensory symptom). Nine of 10 patients who showed dyskinesia preoperatively significant improvement. The mean dose of levodopa in 9 patients was lowered. The mean H and Y score and UPDRS score were improved in on and/or off time in 15 patients. Among patients who were not improved, one patient worsened, and the others showed no change. The mean overall UPDRS off score changed from 76 preoperatively to 44(33%) at 6 months and from 70 to 52(25%) at 1 year. Transient surgical morbidity was showen in four patients and included dysarthria, hypotonia and confusion. CONCLUSION: We conclude that pallidotomy is safe and effective in patients who have levodopa-reponsive parkinsonism with severe symptom fluctuation. Unilateral pallidotomy also considered helpful to ipsilateral symptom. Unilateral pallidotomy can improve all of parkinsonian's symptom and allow to reduce the levodopa medication. Most of patients show satisfactory results.

Cerivastatin is novel HMG-CoA reductase inhibitors. Clinical trials showed no significant differences of serum creatine kiase between cerivastatin and placebo, and cerivastatin-induced myopathy was rarely reported. This beneficial effect of cerivastatin is thought to be related to the the dual pathway metabolism by hapatic CYP3A4 and 2C8. We here report three cases of rhabdomyolysis which is associated with cerivastatin therapy. Two patients had diabetes mellitus, and received cerivastatin(0.8 mg/day) for treating hyperlipidemia and the other patient had chronic renal failure due to diabetic nephropathy and has maintained peritoneal dialysis and received cerivastatin(0.4 mg/day). Within one month of cerivastatin treatment, those patients experienced myalgia or muscle weakness. At that time, laboratory findings including muscle enzyme level, and bone scan finding were compatible with rhadomyolysis. Under the impression of cerivastatin- induced rhabodmyolysis, cerivastatin was withdrwan, and conventional treatment for rhabdomyolysis was started. Clinical course was uneventful, and these patients were discharged with good general condition. In conclusion, cerivastatin is regarded as a safe drug as compared with other statins, but it also causes rhabdomyolysis. Careful history taking and regular follow-up of muscle enzyme levels would be necessary to detect cerivastatin-induced rhabdomyolysis.

PURPOSE: This study was designed to establish standard guidelines to meet the growing health care needs of adolescents by direct assessment of pediatricians' current practices, attitude and obstacles to the primary care of adolescents. MEHTODS: A questionnaire consisting of 9 questions, including personal characteristics of respondents, current health care practice of adolescents, attitude, obstacles to providing adolescent care, interest in further training, roles of Korean Pediatric Society for adolescent medicine, etc., was completed by 214 pediatricians. RESULTS: Among the respondents, 87.4% were in the 4th or 5th decade of age, and 88.8% of respondents were working for private clicins. More than 60% of respondents were managing patients without age limits. Most of the respondents were interested in adolescent medicine. However, approximately one half of all respondents answered that they could not currently provide satisfactory care to their adolescent patients. Obstacles to providing adolescent care include : their image as "baby doctors", lack of knowledge and skills in adolescent medicine, lack of separate hours for adolescents and concern that parents would object to certain types of care. Among respondents who wanted to further training, many were interested in Continuing Medical Education(CME) course, lecture series, introducing reading lists and publishing textbooks, while others expressed their interest in a newsletter and mini-fellowship. Respondents expected the Korean Pediatric Society to play a role in activating the adolescent medicine as a field for pediatric practice through educating adolescents, pediatricians and advertising via mass media. CONCLUSION: Future policy decisions and medical education must respond to these realities in pediatric practice.
