Methods: We evaluated 100 consecutive surgical patients with CM and divided them into the following groups: 80s (34 patients; mean age, 83.9 years), 70s (33 patients; mean age, 73.9 years), and 69 or younger (33 patients; mean age, 60.9 years). The clinical symptoms and physical signs were evaluated and recorded. Results: Although the recovery rate decreased with increasing age, all groups demonstrated a significant improvement in clinical symptoms relative to preoperative values. The Hoffman sign and hyperreflexia of the triceps tendon were, respectively, present in 82% and 88% of patients in the 80s group, 74% and 64% of those in the 70s group, and 69% and 82% of those in the 69 or younger group, with no significant difference among the groups. In contrast, the rates of hyperreflexia of the patellar and Achilles tendons were, respectively, 59% and 32% in the 80s group, 85% and 48% in the 70s group, and 91% and 70% in the 69 or younger group, with significant differences. Conclusions The positivity rate of the lower extremity hyperreflexia decreased significantly with increasing age in patients with CM. The absence of hyperreflexia, particularly lower extremity, is not uncommon in elderly patients with suspected CM.

STUDY DESIGN: Prospective study based on magnetic resonance (MR) imaging of the lumbar spinal root of the intervertebral foramen. PURPOSE: This study was to compare MR three-dimensional (3D) sequences for the evaluation of the lumbar spinal root of the intervertebral foramen. OVERVIEW OF LITERATURE: The diagnosis of spinal disorders by MR imaging is commonly performed using two-dimensional T1- and T2-weighted images, whereas 3D MR images can be used for acquiring further detailed data using thin slices with multi-planar reconstruction. METHODS: On twenty healthy volunteers, we investigated the contrast-to-noise ratio (CNR) of the lumbar spinal root of the intervertebral foramen with a 3D balanced sequence. The sequences used were the fast imaging employing steady state acquisition and the coherent oscillatory state acquisition for the manipulation of image contrast (COSMIC). COSMIC can be used with or without fat suppression (FS). We compared these sequence to determine the optimized visualization sequence for the lumbar spinal root of the intervertebral foramen. RESULTS: For the CNR between the nerve root and the peripheral tissue, these were no significant differences between the sequences at the entry of foramen. There was a significant difference and the highest CNR was seen with COSMIC-FS for the intra- and extra-foramen. CONCLUSIONS: In this study, the findings suggest that the COSMIC-FS sequences should be used for the internal or external foramen for spinal root disorders.

BACKGROUND/AIMS: Diffuse or segmental irregular narrowing of the main pancreatic duct (MPD), as observed by endoscopic retrograde cholangiopancreatography (ERCP), is a characteristic feature of autoimmune pancreatitis (AIP). METHODS: ERCP findings were retrospectively examined in 40 patients with AIP in whom irregular narrowing of the MPD was detected near the orifice. The MPD opening sign was defined as the MPD within 1.5 cm from the orifice being maintained. The distal common bile duct (CBD) sign was defined as the distal CBD within 1.5 cm from the orifice being maintained. Endoscopic findings of a swollen major papilla and histological findings of specimens obtained from the major papilla were examined in 26 and 21 patients, respectively. RESULTS: The MPD opening sign was detected in 26 of the 40 patients (65%). The distal CBD sign was detected in 25 of the 32 patients (78%), which showed stenosis of the lower bile duct. The patients who showed the MPD opening sign frequently showed the distal CBD sign (p=0.018). Lymphoplasmacytic infiltration, but not dense fibrosis, was histologically detected in biopsy specimens obtained from the major papilla. CONCLUSIONS: On ERCP, the MPD and CBD adjacent to the major papilla are frequently maintained in patients with AIP involving the pancreatic head. These signs are useful for diagnosing AIP on ERCP.

Physical performance measures, such as gait speed, one-legged stance and hand-grip strength, are known as assessment measures of motor function and predictors for adverse health outcomes, and widely used for assessing motor function in preventive programs for long-term care or screening of frail elderly. However, there is no standard assessment sheet for feedback of the results. In the present study, an assessment sheet on physical performance measures for community-dwelling older adults was developed. A pooled analysis of data from six cohort studies, including urban and rural areas was conducted as part of the Tokyo Metropolitan Institute of Gerontology Longitudinal Interdisciplinary Study on Aging. The pooled analysis included cross-sectional data from 4683 nondisabled, community-dwelling adults aged 65 years or older. Quintiles were derived according to age and sex group for six physical performance measures, i.e., hand-grip strength, one-legged stance, and gait speed and step length at both usual and maximum paces. The assessment sheets, which indicated the physical performance level according to age and sex, were developed by fitting third order polynomial curves to the data. The reference values in the present assessment sheet were considered to be derived from better represented community-dwelling older adults by using more large-scale population-based cohort data than that in the previous study. The assessment sheet should be useful for feeding back results on physical performance measures to elderly individuals and help them better understand their own physical performance levels.

Objective: The purpose of this study was to assess the treatment outcome in patients with chronic hepatitis C (CHC) using the current standard antiviral therapy when patient were treated in collaboration between hepatologists and primary care physicians (PCPs).Patients and Methods: One hundred and ten patients with CHC were treated with a combination therapy of peginterferon-alpha 2b and ribavirin. Among them, 25 patients were treated by a collaboration between hepatologists and PCPs (collaboration group), whereas 85 patients were treated with exclusively by hepatologists (noncollaboration group). The duration of the therapy was 48 weeks for 58 'difficult- to-treat' patients (genotype 1 with a high load of HCV-RNA; 1H patients) and 24 weeks for the remaining 52 patients (non-1H patients). In the collaboration group, antiviral therapy was initiated and adjusted, if needed, by hepatologists (visits every four weeks), whereas the weekly administration of peginterferon-alpha 2b was performed by PCPs. Clinical characteristics and the treatment outcome were compared between these two groups.Results: The two groups had similar baseline characteristics. By intention to treat, the two groups showed similar rates of treatment-related serious adverse effects (0% vs. 1%, respectively) and dropout rates for adverse effects (8% vs. 13%, respectively). Sustained virologic response rates were also similar between the two groups, being 42% vs. 39% in the 58 1H patients (NS) and 62% vs. 64% in the 52 non-1H patients (NS), respectively.Conclusions: Collaboration between hepatologists and PCPs may be a valid treatment alternative to treat patients with CHC using the current standard antiviral therapy.

Nosocomial infection management is one of the most important subjects in terms of risk management in a hospital. To achieve the nosocomial infection management appropriately, both public relations and information gathering are important. When it comes to publicity, it is desirable that information is offered quickly and efficiently and the personnel are able to access the information easily anytime and wherever they are. As for information gathering, it is also important to collect the information concerning the nosocomial infection promptly, and to tell it quickly to infection management persons including infection control team members. The infection control committee of our hospital has engaged in both publicity and information gathering by using the committee web site established in the LAN of the hospital since January 2004. The web site carries notifications, organization chart, list of committee members, various manuals, guidance of educational activities, infection management, etc. It is also used for questions and answers, and gathering information concerning nosocomial infection. The number of times the web site was accessed was about 200 every month, and was considerable at night and on holidays. This method of using the web site seems to be useful to promote nosocomial infection management.

The whole spectrum of patients infected with hepatitis C virus (HCV) who visited hospitals has not been fully clarified. It is also unknown whether such patients have visited the hospitals regularly thereafter for a long period. We studied 844 consecutive patients with liver diseases who visited our outpatient clinic located in the southern region of Ibaraki Prefecture. Five hundred eighty-three patients were HCV-infected. Among them, three patients were HBsAg-positive and another patient was IgM anti-HAV positive. Thus, 579 patients (68.6%) were considered to have HCV solely as a hepatotropic virus.Of these HCV patients, 60 were asymptomatic carriers and 15 others were unclassified because of the absence of either biopsy or imaging test records of the liver. As to the rest of the HCV patients, acute hepatitis was diagnosed in one patients, chronic hepatitis in 332 patients, cirrhosis in 130 patients and cancer of the liver in 41 patients.About half of the patients undergoing liver biopsy showed F1 in the degree of liver fibrosis. The rate of virological response to interferon mono-therapy in patients infected with genotype 2 was worse than the national average. The poor response was considered to be due to high viral load. It was suggested that the distribution of patients with each genotype was uneven in this region. After five years, the rate of patients still visiting our clinic were 68.1% for those with chronic hepatitis, and 50% for the healthy carriers. We deemed that it was important to clarify whether patients not visiting our clinic are followed up closely in other hospitals.
