Meta AnalysisManagement of agitation, aggression, and psychosis associated with dementia: a pooled analysis including three randomized, placebo-controlled double-blind trials in nursing home residents treated with risperidone.
This analysis used pooled data from three randomized, placebo-controlled trials that examined the efficacy and safety of risperidone for the treatment of agitation, aggression, and psychosis associated with dementia in elderly nursing home residents to assess the risk-benefit of the use of risperidone in this population. The efficacy data (risperidone n=722, placebo n=428) were obtained from the Cohen-Mansfield agitation inventory (CMAI) and behavioral pathology in Alzheimer's disease (BEHAVE-AD) total and subscales. Additionally, clinical global impression (CGI) assessments were performed. ⋯ At the recommended doses, risperidone displayed a favorable risk-benefit profile. Risperidone was well tolerated with respect to EPS, somnolence, and anticholinergic side effects in this elderly population. In view of the risk for CAEs, risperidone, should be targeted towards the treatment of those patients in whom psychotic and behavioral symptoms of dementia are prominent and associated with significant distress, functional impairment or danger to the patient.

Quantitative thermal sensory testing -- value of testing for both cold and warm sensation detection in evaluation of small fiber neuropathy.
Small fiber neuropathy is a common neurological disorder, often missed or ignored by physicians, since examination and routine nerve conduction studies are usually normal in this condition. Many methods including quantitative thermal sensory testing are currently being used for early detection of this condition, so as to enable timely investigation and treatment. This study was conducted to assess the yield of quantitative thermal sensory testing in diagnosis of small fiber neuropathy. ⋯ This study demonstrates that quantitative thermal sensory testing is a fairly sensitive method for detection of small fiber neuropathy especially in patients with normal routine nerve conduction studies.

Trigemino-cardiac reflex during transsphenoidal surgery for pituitary adenomas.
The trigemino-cardiac reflex (TCR) is a well-recognized phenomenon consisting of bradycardia, arterial hypotension, apnea, and gastric hypermotility. It occurs during ocular surgery or other manipulations around the orbit and can also be elicited by stimulation of the central part of the trigeminal nerve during surgery for processes of the cerebellopontine angle. The present retrospective study was conducted to determine if TCR occurs during transsphenoidal surgery in the same way. ⋯ The present results give evidence for the first time that TCR may occur during transsphenoidal surgery in the supine position for resection of pituitary adenomas near the cavernous sinus, leading to a significant decrease in HR and MABP under a standardized anesthetic protocol.
