BACKGROUND AND OBJECTIVES Malignant hyperthermia (MH) is a pharmacogenetic skeletal muscle disorder characterized by a hypermetabolic state after anesthesia with succinylcholine and/ or volatile anesthetics. Various neuromuscular syndromes are associated with susceptibility; however, Moebius syndrome has not been reported. Dantrolene is the drug of choice for treatment. Recurrence may occur in ...

A patient is reported who was on prolonged treatment with dantrolene for spastic paraplegia; he developed a malignant lymphoma which led to his death.

The clinical course and histological changes in the liver during a presumed adverse reaction to the drug dantrolene sodium are described in four patients. After a typical prodrome one developed a moderately severe hepatitis-like illness. Another also had a prodrome but never became jaundiced. In the other two, abnormal liver function tests were detected on routine screening. In each case liver ...

A 25-yr-old man, subsequently shown to be malignant hyperthermia (MH) susceptible by in vitro contracture testing, developed MH during anaesthesia for tonsillectomy. Prompt treatment, including dantrolene, led to rapid resolution of the metabolic crisis. Eighteen hours later the patient's trachea was extubated in the ICU, when he had been stable and apyrexial overnight. Twenty minutes after ext...

Neuroleptic malignant syndrome (NMS) is an uncommon but potentially fatal adverse reaction to neuroleptic drugs, including amisulpride [1,2]. NMS most commonly presents with increased body temperature, muscular rigidity of a 'lead pipe' nature, altered mental status and autonomic dysfunction. Other extrapyramidal movement disorders such as tremor and cogwheel phenomena are also frequently prese...

A 15-year-old girl developed symptoms suggestive of malignant hyperthermia during a laparoscopic appendicectomy for acute appendicitis. The triad of masseter spasm, hypercarbia and hyperthermia within 30 minutes of exposure to triggering factors was present and was treated successfully with dantrolene. She is among a handful of cases known locally. The problems faced in the post-acute phase inc...

The present study investigated the effect of ryanodine receptors (RyRs) in the development and expression of morphine-induced conditioned place preference (CPP). Type 2 RyRs (RyRs-2) in the nucleus accumbens (NAcc) significantly increased in morphine-conditioned mice, whereas type 1, 2, and 3 RyRs in the frontal cortex and ventral tegmental area showed no changes. Intracerebroventricular pretre...
