We present the case of a 26 year-old man who developed normally until he began having difficulty walking at age 12. He subsequently became unable to stand at 15 years old and exhibited mental regression and generalized tonic convulsions by age 20. Magnetic resonance imaging revealed incomplete myelination of cerebral white matter, which resembled that of(More)
An automatic placement algorithm for standard cell and polycell LSI is described, which is constructed on the basis of heuristics for a set of interrelated placement subproblems. The algorithm is incorporated into a hierarchical layout system intended not only for standard cell and polycell LSI but for general cell LSI, by which standard cell and polycell(More)
We reported a 36-year-old man, who suffered from cluster headache (CH) associated with hemicrania continua (HC). The continuous, dull or pressure-type headache appeared on the same side of the CH during the third month of a prolonged cluster period, and fluctuated in the severity of pain. This headache was aggravated when the CH was ameliorated by the(More)
We report on three patients with xeroderma pigmentosum group A (XPA) who showed laryngeal stridor in their 20s. The stridor appeared on feeding and emotional excitation, was exaggerated during respiratory infection and was life-threatening on some occasions. Adduction of the vocal cords during inspiration, observed by laryngoscopy, confirmed laryngeal(More)
A household vehicle transactions model has been developed as a competing risks duration model in this study. The model is developed assuming the following three types of competing risks: replacing one of the vehicles in the household fleet, disposing of one vehicle in the fleet, and acquiring one vehicle to add to the fleet. In addition to the attributes of(More)
STUDY DESIGN Animal study. OBJECTIVE To evaluate pain behavior and neuropeptide changes in the spinal dorsal horn after sciatic nerve compression and application of nucleus pulposus (NP) in rats. SUMMARY OF BACKGROUND DATA The pathomechanisms of lumbar disc herniation pain have not been fully elucidated. Pain-associated neuropeptides, including(More)
PURPOSE Bupivacaine is commonly used for the treatment of back pain and the diagnosis of its origin. Nonunion is sometimes observed after spinal fusion surgery; however, whether the nonunion causes pain is controversial. In the current study, we aimed to detect painful nonunion by injecting bupivacaine into the disc space of patients with nonunion after(More)
Children with acute encephalopathy (AEP) or acute encephalitis(AE) show variable findings in the clinical manifestations and on the neuroimaging. Patients with AE present variable symptoms: disturbance of consciousness, seizure, ataxia, dystonia, abnormal behavior, apnea, and others. This variability depends on the location of lesions including basal(More)
