OBJECTIVE A series of 21 patients with tuberculum sellae meningioma who received surgical treatment is reported. PATIENTS AND METHODS All 9 females and 12 males (mean age 49 years) presented visual disturbances of varying degrees in either one or both eyes. Eighteen of the tumours were less than 3 cm in size, and 3 were larger. Tumour resection of uniform(More)
We investigated why the cerebrospinal fluid (CSF) concentrations of Aβ42 are lower in mild cognitive impairment (MCI) and Alzheimer's disease (AD) patients. Because Aβ38/42 and Aβ40/43 are distinct product/precursor pairs, these four species in the CSF together should faithfully reflect the status of brain γ-secretase activity, and were quantified by(More)
BACKGROUND Microdeletion and microduplication syndromes without characteristic dysmorphic features are difficult to diagnose without chromosomal microarrays. PATIENTS We describe the clinical course and genetic findings of monozygotic twins with intellectual disabilities and autistic features associated with mild facial dysmorphism and microdeletion of(More)
Among the various disorders manifesting dementia, gait disturbance, and urinary incontinence in the elderly population, idiopathic normal pressure hydrocephalus (iNPH) is becoming of great importance. After the publication of the first edition of the Guidelines for Management of Idiopathic Normal Pressure Hydrocephalus in 2004 (the English version was(More)
PURPOSE Previous studies suggest that compression and stretching of the corticospinal tract (CST) potentially cause treatable gait disturbance in patients with idiopathic normal pressure hydrocephalus (iNPH). Measurement of axon diameter with diffusion MRI has recently been used to investigate microstructural alterations in neurological diseases. In this(More)
INTRODUCTION The goals of this study were to examine the usefulness of diffusional kurtosis imaging (DKI) for assessing microstructural changes in the compressed corticospinal tract (CST) among patients with idiopathic normal pressure hydrocephalus (iNPH). METHODS Eleven patients with iNPH (mean age: 73.6 years, range: 65-84), who underwent 3-T magnetic(More)
BACKGROUND Lumboperitoneal shunt surgery has the potential to alleviate symptoms of normal pressure hydrocephalus but the benefits of such surgery have not been tested in a randomised trial. The aim of this trial was to determine the safety and efficacy of the lumboperitoneal shunt surgery for this disorder. METHODS For the open-label randomised(More)
Idiopathic normal pressure hydrocephalus (iNPH) is an elderly dementia caused by abnormal metabolism in the cerebrospinal fluid (CSF). The tap test is the current basis for confirming iNPH, but it shows very low sensitivity, indicating that many patients who might be cured by a shunt operation will be missed. On sodium dodecyl sulfate-polyacrylamide gel(More)
We developed a high-throughput Enzyme-linked immunosorbent assay (ELISA) for measuring α2,6-sialylated transferrin (Tf), based on inhibition of anti-Tf antibody binding to α2,6-sialylated Tf by a lectin, Sambucus sieboldiana Agglutinin (SSA). The inhibition was not observed with other glycoforms, such as periodate-treated, sialidase-treated and(More)
OBJECTIVE Idiopathic normal pressure hydrocephalus (iNPH) is treated with cerebrospinal fluid shunting, and implantation of a ventriculoperitoneal shunt (VPS) is the current standard treatment. The objective of this study was to compare the efficacy and safety of VPSs and lumboperitoneal shunts (LPSs) for patients with iNPH. METHODS The authors conducted a(More)
