A 66-year-old man underwent replacement of the ascending aortic arch for acute aortic dissection (Stanford type A). During surgery, an ePTFE synthetic graft was anastomosed to the left axillary artery to transmit blood from the extracorporeal circulation. During arch branch reconstruction, the left axillary artery was anastomosed end-to-end to a Dacron synthetic graft and the ePTFE synthetic graft used to transport blood, and the terminal anastomotic site of the ePTFE synthetic graft was used. At about 3 months postoperatively, a bulge was noted below the left clavicle, and it was diagnosed as seroma based on CT and aspiration biopsy findings. His condition did not improve despite repeated paracentesis and drainage. The ePTFE was resected and replaced with a Dacron synthetic graft, resulting in case of his seroma.

Objective: To clarify the reason why the target levels of low-density lipoprotein (LDL)-cholesterol are hardly attained.
Methods: The questionnaire was performed for 237 general practitioners on prescription of HMG-CoA reductase inhibitors (statins), just after the publication of “Japan Atherosclerosis Society (JAS) Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases 2007”.
Results: The responses could be summarized as 1) almost all doctors recognized the significance of target levels of LDL-cholesterol; 2) however, general physicians have such a recognition to a lesser extent, compared with cardiologists; 3) when prescribing statins, 66.2% of them had concerns about drug-drug interactions; 4) as the adverse events with statins, they listed creatine kinase (CK) elevations (86.5%), hepatic dysfunction (74.3%) and myalgias/rhabdomyolysis (70.9%); 5) in contrast, less than 20% of them listed the fulminant hepatic failure, gastrointestinal symptoms and fluctuation of blood glucose levels; 6) the threshold value of CK to discontinue statins was 500 IU/L in 44.4% and 200-300 IU/L in 39.6%; and 7) 78.5% of them believed that statins have the pleiotropic ability such a anti-inflammatory effect clinically, in addition to lipid-lowering.
Conclusions: It is important to serve the drug information about the safety of statins to the general practitioners for the management of hyperlipidemia, based on original articles.

We report the first case demonstrating an association between Kawasaki disease (KD) and erythema nodosum (EN). A 3-year-old girl presented with EN as an initial manifestation of KD. At the initial visit, she showed high fever of 40℃, injection of the oropharynx, cervical lymphadenopathy, and red-purple cutaneous nodules, particularly on the lower limbs. She complained of severe pain in the neck and cutaneous lesions. Initially, the development of EN was attributed to Salmonella spp infection, which was detected in stool culture. However, the patient did not respond to high-dose ampicillin/sulbactam to which the Salmonella spp is sensitive. Echocardiography performed as screening for fever of unknown origin revealed medium-sized aneurysms of the left anterior descending artery. EN masked the diagnosis of KD, and the patient developed a coronary artery lesion. KD should be considered in the differential diagnosis of refractory EN in pediatric patients.

We developed three e-learning systems for endoscopists to acquire the necessary skills to improve the diagnosis of early gastric cancer (EGC) and demonstrated their usefulness using randomized controlled trials. The subjects of the three e-learning systems were “detec­tion”, “characterization”, and “preoperative assessment”. The contents of each e-learning system included “technique”, “knowledge”, and “obtaining experience”. All e-learning systems proved useful for endoscopists to learn how to diagnose EGC. Lecture videos describing “the technique” and “the knowledge” can be beneficial. In addition, repeating 100 self-study cases allows learners to gain “experience” and improve their diagnostic skills further. Web-based e-learning systems have more advantages than other teaching methods because the number of participants is unlimited. Histopathological diagnosis is the gold standard for the diagnosis of gastric cancer. Therefore, we developed a comprehensive diagnostic algorithm to standardize the histopathological diagnosis of gastric cancer. Once we have successfully shown that this algorithm is helpful for the accurate histopathological diagnosis of cancer, we will complete a series of e-learning systems designed to assess EGC accurately.

OBJECTIVEThe effects of alcohol consumption on coronary risk factors (CRFs) and insulin resistance (IR) have seemed equivocal in previous studies. This study aimed to clarify the implications of low fasting blood insulin observed in alcohol consumers as related to CRFs and IR.

METHODSA cross-sectional observation in 2133 middle-aged healthy Japanese men for associations of increases in alcohol consumption, fasting serum insulin concentration and serum gammaglutamyltransferase (GGT) activity with the major CRFs of high systolic blood pressure (SBP), fasting serum glucose, triglycerides (TG), total- and LDL-cholesterol (tCh&LDLc) and low serum HDL-cholesterol (HDLc).

RESULTSIncreased alcohol consumption was related to higher SBP, serum GGT, glucose and HDLc, and lower serum LDLc and insulin. Although high serum insulin was significantly related to all of the CRFs in all nondrinkers, moderate drinkers consuming up to 59 ml of alcohol per day and excessive drinkers consuming more, the means of SBP, serum glucose and HDLc were significantly higher and serum LDLc was lower in drinkers than in nondrinkers at any level of serum insulin, indicating that the good and bad profiles of CRFs in alcohol consumers are independent of their low fasting serum insulin. High serum GGT related to increased alcohol consumption and/or body weight was significantly associated with high serum insulin and all of the CRFs in all categories of alcohol consumption.

CONCLUSIONSLow fasting serum insulin observed in drinkers does not imply improved CRFs, and thus may not imply improved IR. High serum GGT may reflect increased IR in both drinkers and nondrinkers.

STUDY DESIGN: Retrospective and comparative study. PURPOSE: We assessed surgical treatment outcomes in patients with thoracic myelopathy due to ossification of the ligamentum flavum (OLF), and OLF combined with ossification of the posterior longitudinal ligament (OPLL) or vertebral fracture (VF) at the same level. OVERVIEW OF LITERATURE: OLF and OPLL cause severe thoracic myelopathy. Osteoporotic VF commonly occurs at the thoracolumbar junction. There have been no investigations of thoracic myelopathy due to OLF and VF. METHODS: Forty patients were divided among three groups: the OLF group (n=23): myelopathy due to OLF, the OLF+OPLL group (n=12): myelopathy due to OLF and OPLL, and the OLF+VF group (n=5): myelopathy due to OLF and VF. We recorded OLF, OPLL, and VF sites and operative procedures. Each patient’s neurological status, according to the Japanese Orthopaedic Association (JOA) score, and walking ability were evaluated pre- and postoperatively. RESULTS: Patients in the OLF+OPLL group were significantly younger than those in the other two groups. The preoperative JOA score was significantly lower in the OLF+VF than OLF group. The final JOA score was significantly lower in the OLF+VF than OLF and OLF+OPLL groups. The JOA score recovery rate was significantly lower in the OLF+VF than OLF group. Final walking ability was significantly worse in the OLF+OPLL and OLF+VF groups than in the OLF group and significantly worse in the OLF+VF than OLF+OPLL group. CONCLUSIONS: Thoracic myelopathy due to OLF+VF occurs primarily in older females, who also exhibit worse preoperative and postoperative neurological status, and worse walking ability, than patients with thoracic myelopathy due to OLF or OLF+OPLL.

OBJECTIVESWith greater concern for efficient resource allocation and profiling of medical care, a case-mix classification was applied for the per-diem payment system in Japan. Many questions remain, one of which is the role of comorbidity and complication (CC) in grouping logic. We examined the association of the number of CC with the length of hospital stay (LOS) and hospital mortality as well as the proportion of LOS high outliers in 19 major diagnostic categories (MDCs).

METHODSThis study was a secondary data analysis embedded in a government research project, including anonymous claims and clinical data during a 4-month period from July 2002. Every 19 MDC, LOS, hospital mortality or proportion of LOS high outliers was compared by the number of CC and presence of any procedures.

RESULTSFrom 82 special function hospitals, 241,268 patients were enrolled in this study. Among all patients, 50.5% were identified without any CCs, 32.4% with one or two, 13.4% with three or four, and 3.7% with over five CCs. The overall mean LOS was 22.15 days and hospital mortality 26.05 cases per 1,000 admissions. In any MDC, LOS and the proportion of outliers increased as the number of CC rose. The mortality rate increased prominently in the respiratory system and the hematology system.

CONCLUSIONSThis study demonstrated that the occurrence of more CC caused longer LOS and higher mortality in some major disease categories. Further study will clarify the association of the weighted CC with resource use through controlling procedures specific for MDC.

Since the rectus femoris muscle is associated with trauma and disorders such as muscle strain, it is often a target for evaluation and treatment. However, in many studies, measurement results were obtained from only a part of the rectus femoris muscle and used as a representative value without considering the differences across the muscle. The rectus femoris muscle may change shape with knee flexion because the structure is complicated; it has an intramuscular tendon. The purpose of this study was to assess the changes in shape of the rectus femoris muscle during flexion of the knee joint in different directions. Twelve lower limbs of 12 male university students were analyzed. The rectus femoris muscle was divided into eight parts, and short-axis images were taken with an ultrasonic diagnostic imaging device at the knee joint; in extension; flexion at 30 °, 60 °, 90 °, and 120 °; muscle thickness; muscle width; and cross-sectional area. It was suggested that the thickness of the rectus femoris muscle increased from “A” to “F” due to knee flexion, and that this increase occurred because of stretching at the same site. In “G,” there was no difference between the angle conditions; conversely, in “H,” the muscle thickness decreased due to knee flexion. It should also be noted that D and E have the greatest muscle thickness when measuring in the knee flexion position.
