The authors note that orthopedists and anesthesiologists with lengthy practice in North Carolina have observed that "members of the Lumbee Indian population have a significantly higher that normal familial incidence of congenital musculoskeletal anomalies, though this has not been documented" (p. 485). Since there is a link between malignant hyperthermia and inheritance, as well as between malignant hyperthermia nd musculoskeletal anomalies, the authors wished to report their experience with a case of malignant hyperthermia, the second documented Lumbee incident, so that North Carolina physicians will be aware that Lumbee patients may be at risk for malignant hyperthermia during or after anesthesia. The acute malignant hyperthermia occurred in the recovery room 2 1/2 hours after the patient had received general anesthesia with isoflurane. Sixteen days later, the patient again needed anesthesia for a craniotomy. Precautions were taken against malignant hyperthermia, but some symptoms recurred ...

Figure 4. A decision tree can be used to calculate conditional probabilities after a positive test result in one parent, assuming that a child is known to be suspectible to malignant hyperthermia (MHS) and that one and only one parent can be MHS. Probabilities of a branch are indicated by italics below the line. (A) Using the "incomplete" testing strategy, the untested parent is assumed to be negative. The probability that the first parents result is a true positive (upper branch) is the positive predictive value (PPV; italics). The probability that it is a false positive (lower branch) is calculated as 1 - PPV. Therefore, the probability of error in the automatic assumption that the second parent is negative is calculated as 1 - PPV. (B) With a "complete" testing strategy, the second parent is also tested. If the first parent had a true-positive result (first upper branch), the second parent must be healthy under our assumptions. Therefore, the probability that diagnostic testing is negative ...

Malignant hyperthermia is a life-threatening disorder, usually triggered by medications given during a general anesthetic. These medications include succinyl choline (a muscle relaxant) and inhaled anesthetics (gases). Only certain individuals are susceptible to malignant hyperthermia. This is thought to be due to a genetic mutation and is inherited as an autosomal dominant trait. It is described as a mutation on the ryanodine receptor and affects calcium distribution in the muscle cells.
This review summarizes the latest evidence on the genetics of malignant hyperthermia susceptibility, guidelines for genetic diagnosis, and the limitations of current genetic screening.
Malignant hyperthermia (MH) is a type of severe reaction that occurs to particular medications used during general anesthesia, among those who are susceptible. Symptoms include muscle rigidity, high fever, and a fast heart rate. Complications can include rhabdomyolysis and high blood potassium. Most people who are susceptible are generally otherwise normal when not exposed. The cause of MH is the use of certain volatile anesthetic agents or succinylcholine in those who are susceptible. Susceptibility can occur due to at least six genetic mutations, with the most common one being of the RYR1 gene. Susceptibility is often inherited from a persons parents in an autosomal dominant manner. The condition may also occur as a new mutation or be associated with a number of inherited muscle diseases, such as central core disease. In susceptible individuals, the medications induce the release of stored calcium ions within muscle cells. The resulting increase in calcium concentrations within the cells ...

Dantrolene is classified as a direct-acting skeletal muscle relaxant. It is currently the only specific and effective treatment for malignant hyperthermia. In isolated nerve-muscle preparation, Dantrium has been shown to produce relaxation by affecting the contractile response of the muscle at a site beyond the myoneural junction. In skeletal muscle, Dantrium dissociates excitation-contraction coupling, probably by interfering with the release of Ca2+ from the sarcoplasmic reticulum. In the anesthetic-induced malignant hyperthermia syndrome, evidence points to an intrinsic abnormality of skeletal muscle tissue. In selected humans, it has been postulated that "triggering agents" (e.g.,general anesthetics and depolarizing neuromuscular blocking agents) produce a change within the cell which results in an elevated myoplasmic calcium. This elevated myoplasmic calcium activates acute cellular catabolic processes that cascade to the malignant hyperthermia crisis. It is hypothesized that addition of ...

Malignant hyperthermia susceptibility (MHS) is an autosomal dominant disorder of skeletal muscle which manifests as a potentially fatal hypermetabolic crisis triggered by commonly used anaesthetic agents. The demonstration of genetic heterogeneity in MHS prompted the investigation of the roles played by calcium regulatory proteins other than the ryanodine receptor (RYR1), which is known to be linked to MHS in fewer than half of the European MHS families studied to date. Previously, we have excluded the genes encoding the skeletal muscle L-type voltage-dependent calcium channel alpha(1)-, beta(1)- and gamma-subunits as candidates for MHS. In this report, we describe the cloning and partial DNA sequence analysis of the gene encoding the alpha(2)/delta-subunits, CACNL2A, and its localization on the proximal long arm of chromosome 7q. A new dinucleotide repeat marker close to CACNL2A was identified at the D7S849 locus and tested for linkage in six MHS families. D7S849 and flanking genetic markers ...

Causes of hyperpyrexia - What is "malignant hyperpyrexia"? Anesthesia related. Malignant hyperpyrexia is another term for malignant hyperthermia. This disorder is caused mainly by gas anesthetics and depolarizing paralytics (eg succinylcholine) in patients with a genetic mutation (runs in families). When these patients are exposed, they may experience a sudden increase in cellular metabolism, potentially resulting in death if not caught early and treated aggressively.
Equine Malignant Hyperthermia (EMH) is a life-threatening pharmacogenetic disorder of skeletal muscle elicited by halogenated anesthetics, depolarizing muscle relaxants, and stress. Dysfunction of RyR1 (calcium release channel of the sarcoplasmic reticulum of skeletal muscle) results in excessive release of calcium into the myoplasm-triggering cascade events that lead to a hypermetabolic state and ultimately cell death. Clinical and laboratory manifestations include tachycardia, hyperthermia, muscle rigidity, rhabdomyolysis, respiratory and metabolic acidosis, and electrolyte derangements. ...

Ivanhoe Newswire) -- A young fit athlete who appears no different from the others on his football team dies suddenly during practice on a hot summer day. What could make this happen? According to new studies some physically fit young people could have a genetic mutation that makes them more sensitive to heat. Researchers led by those at Baylor College of Medicine may have identified a molecule that could reduce that threat.. Dr. Susan Hamilton chair of molecular physiology and biophysics at BCM, studies the ryanodine receptor 1(RyR1) which is linked to a deadly disorder called malignant hyperthermia. People with this disorder suffer a life-threatening rise of temperature when given a certain kind of general anesthesia. When mice with this mutation exercise in a hot room or are even exposed for a short time to the temperatures of a hot summer, they demonstrate all the symptoms of malignant hyperthermia before they die. New evidence suggests that this heat sensitivity is also found in humans with ...
Patrick Welchs MH Story….. If by sharing my detailed MH story helps anyone understand their situation better, my goal in writing this has been achieved. I am so happy to hear that those who wrote their story have helped us learn more about this crazy rare medical condition. My name is Patrick Welch and here is my MH story…. On a Friday, in the beginning of October 2018, I woke up at 3:00 AM with severe stomach pain. I thought if I switched positions it would go away, but it did not. At 7:30 AM, my wife, Emily, left for work thinking nothing was wrong, just that I might have eaten something that wasnt the best. However, I still was in pain that was not going away. Around 10:00 AM, I reached out to my wife and mentioned something wasnt right and I needed to be taken to the hospital. My wife ended up closing the pharmacy where she works at about 1:30 PM. She raced home to pick me up. We dropped of our son and daughter with a friend who agreed to watch them and we rushed to the ...

In addition to the shift in the I-V relationship for L-type currents of R163C Het and Hom myotubes, we found that this MH mutation caused an increased responsiveness to the dihydropyridine agonist ±Bay K 8644. In particular, L-type currents of MHS R163C myotubes were potentiated to a greater degree (Hom , Het) than WT myotubes (Fig. 4). This observation suggests that one of the retrograde effects of R163C mutation on the L-type channel activity of the DHPR is to facilitate entry of the channel into the long-open gating state (i.e., mode 2; Nowycky et al., 1985), which might explain the enhanced potentiation by ±Bay K 8644. Interestingly, Bay K 8644 enhances pharmacologically (halothane or isofluorane) induced contractures in both swine and human MHS muscle (Williams et al., 1991; Adnet et al., 1992), consistent with the idea that altered L-type current may contribute to the pathogenesis of this disease.. Compared with previous reports on the inactivation of L-type current in "normal" human ...

Ryanodine receptor isoform-1 (RyR1) is a major calcium channel in skeletal muscle important for excitation-contraction coupling. Mutations in the RYR1 gene yield RyR1 protein dysfunction that manifests clinically as RYR1-related congenital myopathies (RYR1-RM) and/or malignant hyperthermia susceptibility (MHS). Individuals with RYR1-RM and/or MHS exhibit varying symptoms and severity. The symptoms impair quality of life and put patients at risk for early mortality, yet the cause of varying severity is not well understood. Currently, there is no Food and Drug Administration (FDA) approved treatment for RYR1-RM. Discovery of effective treatments is therefore critical, requiring knowledge of the RyR1 pathway. The purpose of this review is to compile work published to date on the RyR1 pathway and to implicate potential regions as targets for treatment. The RyR1 pathway is comprised of protein-protein interactions, protein-ligand interactions, and post-translational modifications, creating an activation
Masseter spasm has a spectrum of severity, ranging from a mild increase in jaw tension to jaws of steel. A patient who exhibits marked rigidity of the jaw muscles should not be discharged. Overnight observation is required for temperature rise, myoglobinuria, elevated CK levels, or progression to an MH episode. Patients who experience milder increases in jaw tension should be observed for signs and symptoms of MH for at least 12 hours. If there is evidence of myoglobinuria, dark cola-colored urine, increase in temperature, pulse rate, or abnormality of acid-base balance, the patient should be admitted and observed overnight.. ° What equipment preparation should be done before surgery on an MHS patient?

Knowledge of the molecular bases of a number of conditions that affect muscle has advanced greatly in recent years. Understanding of the molecular basis of Duchenne-type muscular dystrophy was greatly enhanced when it was discovered that it was due to mutations in the gene encoding dystrophin. Significant progress has also been made in understanding the molecular basis of malignant hyperthermia, a serious complication for some patients undergoing certain types of anesthesia. Heart failure is a very common medical condition, with a variety of causes; its rational therapy requires understanding of the biochemistry of heart muscle. One group of conditions that cause heart failure is the cardiomyopathies, some of which are genetically determined. NO has been found to be a major regulator of smooth muscle tone. Many widely used vasodilators-such as nitroglycerin, used in the treatment of angina pectoris-act by increasing the formation of NO. Muscle, partly because of its mass, plays major roles in ...
