OBJECTIVE The aim of this study was to explore the pathomechanism underlying the reduction of serum creatinine (Cr) concentrations in spinal and bulbar muscular atrophy (SBMA). METHODS We evaluated blood chemistries, motor function, and muscle mass measured by dual-energy X-ray absorptiometry in male subjects with SBMA (n = 65), amyotrophic lateral(More)
This study aimed to evaluate various metabolic parameters in patients with spinal and bulbar muscular atrophy (SBMA), to investigate the association between those indices and disease severity, and to explore the underlying molecular pathogenesis. We compared the degree of obesity, metabolic parameters, and blood pressure in 55 genetically confirmed SBMA(More)
OBJECTIVE To evaluate the prognosis and progression of spinal and bulbar muscular atrophy (SBMA), a rare X-linked motor neuron disorder caused by trinucleotide repeat expansion in the AR (androgen receptor) gene, after long-term androgen suppression with leuprorelin acetate treatment. METHODS In the present natural history-controlled study, 36 patients(More)
Neuronal intranuclear inclusion disease (NIID) is a slowly progressive neurodegenerative disease characterized by eosinophilic hyaline intranuclear inclusions in the central and peripheral nervous system, and also in the visceral organs. NIID has been considered to be a heterogeneous disease because of the highly variable clinical manifestations, and(More)
Development and growth of hematopoietic tissue outside of the bone marrow is termed extramedullary hematopoiesis (EMH). It occurs in patients with hematological diseases such as myelofibrosis and thalassemia. Liver and spleen are the usual sites of EMH. However, spinal cord compression caused by EMH is a rare complication. A 65-year-old man with(More)
We retrospectively studied the clinical features and the outcome of first acute symptomatic seizure in elderly. The subjects were 457 patients, who were more than 15 years old, and whose electroencephalograms were available in our hospital. The subjects were divided into two groups, the elderly (236 patients; age more than 60 years, mean age; 73.2±8.2, 105(More)
The aim of this study was to characterize the respiratory function profile of subjects with spinal and bulbar muscular atrophy (SBMA), and to explore the underlying pathological mechanism by comparing the clinical and biochemical indices of this disease with those of amyotrophic lateral sclerosis (ALS). We enrolled male subjects with SBMA (n = 40) and ALS(More)
Intramedullary spinal cord hemorrhage (hematomyelia) is rare and usually related to trauma. Spinal vascular malformations such as intramedullary cavernomas and intradural arteriovenous malformations are the most common cause of atraumatic hematomyelia. Other considerations include warfarin or heparin anticoagulation, bleeding disorders, spinal cord tumors,(More)
Objectives This study aimed to evaluate swallowing dysfunction in patients with spinal and bulbar muscular atrophy and to identify the most appropriate method of assessing swallowing dysfunction using a videofluoroscopic swallowing study. Methods In the videofluoroscopic swallowing study, patients were instructed to swallow 3 mL of 40% weight/volume barium(More)
