Two patients with muscle weakness caused by amyloid myopathy are described. Characteristic features such as pseudohypertrophy and abnormal firmness, and tumours of muscles were absent. It is suggested that muscle weakness in amyloid myopathy is caused by layers of amyloid covering muscle fibres. In middle aged or elderly patients with proximal muscle weakness the diagnosis of amyloid myopathy s...

Key points • Fingerprint body is a rare congenital myopathy. • Only 5 cases of fingerprint myopathy have been described to date. • Fingerprint myopathy is defined by subsarcolemmal inclusions on muscle biopsy; the inclusions have a characteristic lamellar pattern on electron microscopy. • The genetic basis of fingerprint myopathy is not yet known. • An increasing number of protein aggregate myo...

Long-term steroid use has a well-documented risk of myopathy that imposes functional limitations for patients and challenges for health care providers. Proximal weakness from steroid myopathy affects support structures around the pelvic girdle and likely predisposes patients to somatic dysfunction. To the authors' knowledge, there are no prior reports in the literature that describe an osteopat...

BACKGROUND Acute myopathy following mechanical ventilation for near-fatal asthma (NFA) has been described recently, and some researchers have suggested that this complication is related to the use of neuromuscular blocking agents (NMBAs) and corticosteroids (CSs). OBJECTIVES To determine the incidence of acute myopathy in a group of patients and to examine the most important predictors of its...

Aims: Hepatitis B virus infection is a global health concern. Although primarily affects hepatocytes, it sometimes develops disease manifestations outside the liver and can present as full fledged proximal myopathy. 
 Presentation of Case: We report 68-year-old man presenting with progressive bilateral lower limb weakness for last 14 days. The was associated pain one episode fever. Examina...

Myopathy, which clinically shows muscular pain (myalgia), weakness, cramps, stiffness and spasm, is one of neuromuscular disorders due to inflammation and/or dysfunction of muscle fibers. “Myositis”, which is a general term for inflammation of the muscle, is pathologically an inflammatory myopathy seen seen mainly in autoimmune disorders including dermatomyositis (DM). The myopathy is classifie...

strongyloides stercoralis is a free living tropical and semitropical soil nematode which its larva penetrates skin. it can complete its life cycle in human body and causes autoinfection. most patients have no frank symptoms. but respiratory, gastrointestinal and skin manifestation may occur. we report a 76 year old man admitted to emergency room with muscle weakness, dyspnea, nausea, vomiting w...

Background: Congenital myopathy-13 (CMYP13), also known as Bailey-Bloch congenital myopathy and Native American (NAM), is a condition caused by biallelic missense pathogenic variants in STAC3, which encodes an important protein necessary for the excitation-relaxation coupling machinery muscle. Patients with STAC3 often present weakness arthrogryposis, cleft palate, ptosis, myopathic facies, sho...

BACKGROUND GNE myopathy is characterized by early-adult-onset distal myopathy sparing quadriceps caused by mutations in the GNE gene encoding UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase, an enzyme in the sialic-acid synthesis pathway. CASE REPORT A 27-year-old Korean woman presented a rapid deterioration in strength of the distal lower limbs during her first pregnancy. She ...

Fibrotic myopathy of the iliopsoas muscle developed in a dog, following extensive migration of a grass awn within the muscle and adjacent subcutaneous tissue. The dog was initially presented for evaluation of a fluctuant swelling over the right flank region. The clinical and imaging findings were suggestive of iliopsoas fibrotic myopathy and the diagnosis was confirmed by histopathology. This i...
