Fsh muscular dystroph

OBJECTIVES: To compare muscle and bone health markers in adult males (aged 20-59 yrs) with and without muscular dystrophy (MD). METHODS: Participants included 11 Fascioscapulohumeral (FSH), 11 Becker's (Be), 9 limb girdle (LG), 11 Duchenne (DMD), and 14 non-dystrophic controls (CTRL). Physical activity was assessed using Bone (BPAQ) and disability specific (PASIPD) questionnaires. Bone QUS provided T- and Z scores from the Distal Radius (DR) and Mid-shaft tibia (MST)...

We report the case of a 57-year-old woman, who presented with progressive weakness of ankle's dorsiflexors. Electromyography showed bilateral myogenic patterns in the anterior tibialis predominantly in the left side. Muscle biopsy of the right tibialis anterior showed non specific dystrophic changes. The familial evaluation revealed a son showing scapuloperoneal amyotrophy and facial involvement. Analysis of the propositus' DNA showed a mutation at locus 4q35, characteristic of facioscapulohumeral muscular dystrophy...

Resting intracellular calcium activity was recorded in three kinds of human muscle cells in culture: normal (control) and dystrophic (DMD and FSH), by means of a ratiometric fluorescence method using the calcium probe Indo-1 under laser illumination. DMD cells are characterized by a lack of dystrophin whereas FSH cells express normal dystrophin. The aim of this study was to determine whether, in dystrophin-deficient muscle cells (DMD), contraction destabilized internal calcium homeostasis. Muscle cells were cocultured with rat spinal cord explants to improve the maturation of human myotubes up to the stage where contraction appears...

Life span, causes of death, weight of heart, liver, brain, and main pathological changes of internal organs were analysed on 329 autopsy cases of muscular dystrophies. These included 249 cases of Duchenne muscular dystrophy (DMD), 3 Becker muscular dystrophies (BMD), 14 limb-girdle muscular dystrophies (LGMD), 3 fascioscapulohumeral muscular dystrophies (FSH), 18 Fukuyama type congenital muscular dystrophies (FCMD) and 17 myotonic dystrophies (MyD). In DMD the life span has definitely prolonged in recent years...

Gangliosides of healthy and pathologic muscles (amyotropic lateral sclerosis and facio-scapulo-humeral muscular dystrophy) were studied. Total ganglioside content of the affected muscles was approximately 2 fold higher than the unaffected muscles. Our results showed that ALS muscle contained a ganglioside which was absent in the unaffected and FSH muscular dystrophic muscles. Based on the results of hydrolysis with Vibrio cholerae neuraminidase and subsequent reactivity of the asialo derivative towards anti-globotetraosylceramide, we propose that the ALS ganglioside is sialosylglobtetraosylceramide, NeuAc(alpha 2-3)Ga1NAc(beta 1-3)Ga1(alpha 1-4)Ga1(beta 1-4)G1c-Cer...

LHRH-stimulated LH and FSH secretion was studied in hemipituitaries, in vitro, obtained from several dystrophic mouse mutants (male: 129/ReJ-dy; 129B6F1/J-dy; C57BL/6J-dy and C57BL/6J-dy2J; female: 129B6F1/J-dy) and a dystrophic hamster mutant (male and female CHF-147). Without exception, pituitary tissue from dystrophic animals released significantly more FSH than did tissue obtained from controls. LH secretion was more variable; in the male mice released was inhibited, whereas in the male dystrophic hamsters secretion was elevated above normal...

We report a sporadic case of 12 years old boy with facioscapulohumeral dystrophy (FSHD), sensorineural hearing loss and exudative angioma of bilateral retina. His hearing loss was noted at 9 years, followed by muscle weakness of his right upper extremity at 11 years. Complete neurological examination at 12 years revealed FSH type distribution of muscle weakness with high serum CK level (330 U/L), moderate sensorineural hearing loss and exudative angiomas of bilateral retina. The biopsy from biceps brachii muscle showed advanced dystrophic changes with a dense inflammatory cell infiltration predominating on perivascular distribution and type II fiber predominance...
