Significance of quantitative sensory testing in the diagnosis of diabetic peripheral neuropathy.
To investigate the significance of quantitative sensory testing in the diagnosis of early diabetic peripheral neuropathy. ⋯ Quantitative sensory testing is sensitive for the diagnosis of diabetic peripheral neuropathy, especially for warm thresholds in the dorsum of the foot. Quantitative sensory testing is necessary to assist nerve conduction studies in the diagnosis of early diabetic peripheral neuropathy.

Sleep-wake transition in narcolepsy and healthy controls using a support vector machine.
Narcolepsy is characterized by abnormal sleep-wake regulation, causing sleep episodes during the day and nocturnal sleep disruptions. The transitions between sleep and wakefulness can be identified by manual scorings of a polysomnographic recording. The aim of this study was to develop an automatic classifier capable of separating sleep epochs from epochs of wakefulness by using EEG measurements from one channel. ⋯ In addition, the sleep-wake transitions were elevated in hypocretin-deficient patients. It is concluded that the classifier shows high validity for identifying the sleep-wake transition. Narcolepsy with cataplexy patients have more sleep-wake transitions during night, suggesting instability in the sleep-wake regulatory system.

An audit of continuous EEG monitoring in the neurological-neurosurgical intensive care unit.
The use of long-term continuous EEG (cEEG) monitoring in neurological-neurosurgical intensive care units (NSICU) has witnessed an exponential increase. We decided to do an audit of the long-term cEEG monitoring in our NSICU over the past 7 years (2005-2011). The study was performed to determine technical and staffing consideration for the future. ⋯ The use of long-term cEEG monitoring in the NSICU is expected to further increase in the coming years. Stricter clinical criteria for undertaking cEEG recordings are likely to increase the role and usefulness of this procedure.
