Abstract:
Statin-induced necrotising autoimmune myopathy (SINAM) is a rare disease characterised by proximal muscle weakness and elevated creatine kinase levels that is usually in the thousands. Anti-3-hydroxy-3-methyl glutaryl co-enzyme A reductase (HMGCR) antibodies are associated with SINAM. Autoimmune hepatitis (AIH) is an inflammatory disease of the liver that is usually of unknown aetiology but can also be associated with concurrent extrahepatic autoimmune disorders. We are reporting a case of biopsy proven AIH associated with SINAM in a patient presenting with oropharyngeal dysphagia. The patient had elevated anti-HMGCR antibodies and anti-smooth muscle antibodies. SINAM and AIH were confirmed by muscle biopsy and liver biopsy, respectively. The patient had complete resolution of his symptoms and complete normalisation of his liver function tests after 6 months of the treatment.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
