Because some patients with NMD have sometimes experienced similar problems during anesthesia there have been claims that patients with NMD may also have MH. Involves respiratory, bulbar, and extra-ocular muscles
MH has been linked to a rare disorder of muscle called Central Core disease and King Denborough Syndrome, a rarer muscle syndrome. However, it is generally accepted that the only neuromuscular condition truly related to MH is Central Core Disease …
Central core disease is characterised by muscle weakness, skeletal deformities and susceptibility to malignant hyperthermia. Central Core Disease. The clinical presentation of central core disease (CCD) (OMIM 117000) is highly variable and symptoms can vary from clinically very mild to severe congenital myopathy with hypotonia, skeletal abnormalities, and scoliosis. Central core disease is a rare but distinct genetic entity transmitted primarily by autosomal dominant inheritance, although recessive and sporadic cases occur.
Central Core Disease. MD is x-linked recessive, risk for hyperK w/ sux leading to fatal Rhabdomolysis. Malignant Hyperthermia during Sevoflurane Anesthesia in a Child with Central Core Disease You will receive an email whenever this article is corrected, updated, or cited in the literature.
Central Core Disease is most associated w/ MH.
Central core disease has been reported to be associated with malignant hyperthermia.
CCD is also associated with muscular and skeletal abnormalities such as abnormal curvature of the spine (scoliosis), hip dislocation, and joint deformities. Non-progressing.
[1,2,3]Patients with CCD have been reported to experience a variety of life-threatening … Because some patients with NMD have sometimes experienced similar problems during anesthesia there have been claims that patients with NMD may also have MH. Prevalence is unknown because of variable expression and incomplete penetrance.
[Article in Japanese] Jimi N, Izumi K, Sumiyoshi R, Mizuno K. Central core disease (CCD) is a dominantly inherited congenital myopathy. However, it is generally accepted that the only neuromuscular condition truly related to MH is Central Core Disease (CCD), although this is not always the case. Central core disease (CCD) is an inherited (mostly dominant) neuromuscular disorder characterised by central cores in type I fibres on muscle biopsy and clinical features of a congenital myopathy. Mutations in the ryanodine receptor-1 gene (RYR1) on chromosome 19q13 are responsible for central core disease and malignant hyperthermia (Malicdan & Nishino, 2011). Sir, Central core disease (CCD), an inherited disorder, presents with hypotonia, proximal weakness, scoliosis, hip dislocation and susceptibility to malignant hyperthermia (MH). Usually, there is mild floppiness in infancy, delayed milestones, and moderate limb weakness, which do not worsen much over time. Children with central core disease may have life-threatening reactions to general anesthesia. Central core disease (CCD) is a rare hereditary myopathy, which presents clinically with muscle weakness of variable degree and histologically with central cores in the muscle fibers .
Central core disease (CCD) is a rare genetic neuromuscular disorder that is classified as a congenital myopathy, meaning that it is a muscle disorder (myopathy) that is present at birth (congenital). In some cases, an affected person inherits the mutation from one affected parent.Other cases may result from new mutations in the gene. Associated in approximately 25 per cent of cases with malignant hyperthermia because of gene … Variable weakness.
Central Core Disease comes from a disorder on the same gene, RYR1 on chromosome 19. Axial weakness .
Central core disease is most often inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Common features are floppy infant syndrome, delayed motor milestones, and generalized muscle hypotonia during adolescence. [Anesthetic Management of a Patient with Central Core Disease for Scoliosis Surgery].
Total intravenous anaesthesia was used because of the combination of potential malignant hyperthermia, severe kyphoscoliosis and extensive spinal scarring.

These cases occur in people with no history of the disorder in their family.
Neonatal hypotonia.
Central core disease varies among children with regard to the severity of problems and the degree of worsening over time.
