OBJECTIVE The clinical significance and characteristics of neuropathy caused by folate deficiency remain to be established. METHODS We examined the clinicopathologic features of 18 consecutive patients with neuropathy caused by folate deficiency who presented with low serum folate levels but normal blood thiamine and serum cobalamin levels in the absence(More)
BACKGROUND This study attempted to clarify the duration of effects of 3- and 6-month comprehensive health education programs based on hot spa bathing, lifestyle education and physical exercise for women at 1-year follow-up. METHODS We examined middle-aged and elderly women who were randomly divided into two groups and followed up them for one year. Spa(More)
We propose a new architecture for trust management in ubiquitous environments that deals with RBAC policy, digital signatures, and user presence in a uniform framework. The proposed architecture includes inferences about user presence from incomplete sensor signals based on the hidden Markov model. We implemented a prototype system for a connection service(More)
OBJECTIVE To examine the morphology of Schwann cells and endoneurial microvessels with electron microscopy. METHODS Sural nerve biopsy specimens from 49 patients with familial amyloid polyneuropathy (FAP) with transthyretin Val30Met mutation were assessed. Patients included 11 early-onset cases from endemic foci and 38 late-onset cases from nonendemic(More)
To elucidate the significance of uncompacted myelin lamellae (UML) and ion channel disruption at the nodes of Ranvier in the polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome, we evaluated sural nerve biopsy specimens from 33 patients with POEMS syndrome and from 7 control patients. Uncompacted myelin(More)
The newly recognized entity IgG4-related disease (IgG4-RD) is characterized by an elevated IgG4 serum concentration, swelling of organ, and tissue infiltration by IgG4-positive plasma cells with fibrosis. IgG4-RD has been reported in various organs. In the field of neurology, hypophysitis and hypertrophic pachymeningitis have been known to be related to(More)
We herein report a case of peripheral neuropathy following exposure to large amounts of glyphosate-based herbicide. A 70-year-old man suffered from pain and purpura in the left sole following exposure to glyphosate-based herbicide. Pain and purpura spread to the opposite side and increased in severity. Mild weakness of the lower limbs was also observed. A(More)
A patient with chronic alcoholism presented with myelopathy and low serum folate and cobalamin levels. A 42-year-old alcoholic man had gait disturbance for 4 months. A neurological examination revealed marked spasticity with increased deep tendon reflexes and extensor plantar responses of the lower limbs. His cobalamin level was decreased and his serum(More)
