The ascidian larva is often regarded as an organism close to the ancestral form of chordates, while it is generally accepted that the Spemann's organizer is absent from ascidian embryos. Not is one of the genes expressed in the organizer to execute functions in vertebrate embryos. To address the extent of conservation of Not gene expression among ascidians(More)
BACKGROUND AND AIMS Treatment of anorectal sepsis requires prompt surgical drainage, but it is important to identify any associated anal fistula for preventing recurrence. We evaluated whether microbiological analysis and/or endoanal ultrasonography could be used to predict anal fistula in patients with acute anorectal sepsis. METHODS Five hundred(More)
BACKGROUND AND AIMS This study was undertaken to determine the incidence of and risk factors for anal incontinence after fistulotomy for intersphincteric fistula-in-ano. We also evaluated the role of anal manometry in preoperative assessment of intersphincteric fistula. MATERIALS AND METHODS A prospective, observational study was undertaken in 148(More)
Constant exposure to new and persisting antigens and the need to replace cellular attrition with newly built cells lead to profound remodeling of the immune system after the age of 50 years. The impact of the immunosenescence process varies amongst the different cellular subsets represented within the immune system. Emerging data suggest that progressive(More)
We report a patient with polymyositis (PM) associated with myasthenia gravis (MG). Both disorders had been controlled for around 15 years by oral prednisolone and a cholinesterase inhibitor following surgical removal of invasive thymoma and radiotherapy, but muscular weakness due to myalgia and an increase in serum levels of myogenic enzymes, mainly(More)
PURPOSE This study was undertaken to determine the incidence of and risk factors for urinary retention after surgery for benign anorectal disease. METHODS We reviewed 2,011 consecutive surgeries performed under spinal anesthesia for benign anorectal disease from January through June 2003 to identify potential risk factors for postoperative urinary(More)
Thalamic stimulation alleviated coarse action tremor in a patient with spinocerebellar degeneration (SCD) and led to substantial improvement in daily functioning, though disability from ataxia remained. Intraoperative microrecording revealed a significant correlation between neuronal activity of the ventral intermediate nucleus (Vim) and tremor(More)
OBJECTIVE To investigate the clinical usefulness of measuring diameters of spinal nerve roots on magnetic resonance imaging (MRI) in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with regard to the diagnosis and estimation of neurofunctional impairment. PATIENTS AND METHODS Fourteen patients with CIDP (mean age,(More)
We report a patient with systemic lupus erythematosus (SLE) who showed periodic peritonitis with spontaneous remission. She showed compound heterozygous mutations in the MEFV gene, leading to the diagnosis of familial Mediterranean fever (FMF). Oral colchicine successfully reduced the severity and frequency of her peritonitis. SLE occasionally manifests(More)
We report a patient with polymyalgia rheumatica (PMR) who showed a relapse soon after tapering of oral prednisolone. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were quickly normalized after the re-increase in oral prednisolone, and muscle pain and stiffness gradually improved in parallel with a decrease in serum amyloid A (SAA).
