facioscapulohumeral muscular dystrophy (fshd)is characterized by weakness of the facial, scapular muscles  and the dorsiflexors of the foot. severity in this disorder is highly variable. approximately 95% of individuals with fshd phenotype have type 1 fshd, with d4z4 allele of between one and ten repeat units and about 5% have type 2 fshd with mutations in the chromatin modifier smchd1gene whic...

facioscapulohumeral muscular dystrophy (fshd) is a common inherited muscular dystrophy presented clinically with slowly progressive weakness and wasting of facial and limb muscles and rare bulbar muscle involvement. we present herein a 70-year-old man who was a known case of fshd with complaint of 15-day history of progressive difficulty in chewing and dysarthria and was found to have myastheni...

muscular dystrophies are inherited disorders that cause progressive muscle weakness (myopathy) and atrophy (loss of muscle mass) due to defects in one or more genes required for normal muscle function. some of the genes responsible for these conditions have been identified .there are a number of different types of muscular dystrophy. the primary symptom for most types is muscle weakness, althou...

Introduction. The association of celiac disease and facioscapulohumeral muscular dystrophy was not reported earlier in the literature. Case presentation. A 35-year-old woman diagnosed clinically with facioscapulohumeral muscular dystrophy 23 years ago. In the family history patients’ mother was diagnosed with facioscapulohumeral muscular dystrophy, too. Physical examination revealed bilateral f...

We report a case of birdshot chorioretinopathy (BSCR) in a patient with facioscapulohumeral muscular dystrophy (FSHD). A 40-year-old male with history of facioscapulohumeral muscular dystrophy with significant facial diplegia and lagophthalmos presents for an evaluation of bilateral choroiditis with vasculitis and optic disc edema. Clinical examination included fundus and autofluorescence photo...

This chapter places emphasis on patients with more weakness in proximal than distal parts. The most common type of proximal muscular dystrophy is Duchenne muscular dystrophy (DMD). Due to rapid deterioration, DMD can be seen as a severe form of muscular dystrophy. Other types of proximal muscular dystrophies have a slower rate of disease progression compared to DMD, such as Beck muscular dystro...

Muscular dystrophies are a heterogeneous class of inherited disorders presenting with different clinical, genetic, and biochemical features. Muscular dystrophies include Duchennemuscular dystrophy (DMD) and Becker muscular dystrophy (BMD) myotonic dystrophy (DM), oculopharyngeal muscular dystrophy (OPMD), facioscapulohumeral muscular dystrophy (FSHD), limb-girdle muscular dystrophy (LGMD), dist...

Ribosome concentration, ribosome distribution on sucrose density gradients, and in-vitro ribosomal amino-acid incorporation (noncollagen and collagen synthesis) were studied in muscle biopsy samples obtained from 30 patients with Duchenne muscular dystrophy, seven patients with Becker muscular dystrophy, and 10 with facioscapulohumeral muscular dystrophy. Ribosome concentration was normal in Du...

Single motor unit potentials recorded from surface electrodes over the extensor digitorum brevis muscle and evoked by stimulation of the anterior tibial nerve at the ankle were obtained by a computer subtraction method. Their latencies, durations, amplitudes, and areas were measured in control subjects and patients with Duchenne, limb-girdle, facioscapulohumeral, and myotonic muscular dystrophy...
