Congenital muscular dystrophies

Integrin α7 encoded by ITGA7 is highly expressed in skeletal and cardiac muscle and contributes to sarcolemmal stability by binding to laminin α2. Three unrelated patients were previously reported with ITGA7-linked congenital muscular dystrophy. Here, we report three patients from two unrelated families pr esenting with adult-onset cardiac arrhythmia and respiratory weakness due to recessive null mutations in ITGA7. Patient I, a 51-year-old male presented with delayed motor milestones, stridor since birth, cardiac arrhythmia (frequent ventricular ectopy, non-sustained ventricular tachycardia and prema ture conduction disease) requiring ICD at 46 years.

Muscular dystrophies are debilitating disorders that result in progressive weakness and degeneration of skeletal muscle. Although the genetic mutations and clinical abnormalities of a variety of neuromuscular diseases are well known, no curative therapies have been developed to date. The advent of genome editing technology provides new opportunities to correct the underlying mutations responsible for many monogenic neuromuscular diseases. For example, Duchenne muscular dystrophy, which is caused by mutations in the dystrophin gene, has been successfully corrected in mice, dogs, and human cells through CRISPR/Cas9 editing. ...

CONCLUSION: We report the successful management of anesthesia without lethal arrhythmia in a patient with ARVC and an ICD. An adequate amount of analgesia should be administered during general anesthesia to maintain adequate anesthetic depth and to avoid stress and pain. PMID: 32473832 [PubMed - as supplied by publisher]

VERDICT: The hypothesis that the 4-aminoquinolines chloroquine and hydroxychloroquine may be beneficial in the treatment of COVID-19 is a weak one, based on poor mechanistic reasoning and inconsistent results of studies in vitro, in laboratory animals, and in humans. It is likely that even if chloroquine and hydroxychloroquine are effective in COVID-19, the beneficial effects will be small. The risks of adverse reactions to these drugs may be increased in patients who are acutely ill with severe COVID-19, in many of whom high doses are being used. Macrolide antibacterial drugs, such as azithromycin, clarithromycin, ery...

Electrical stimulation (ES) by peripheral (transpalpebral/transorbital/transcorneal) approach seems to currently be one of the most promising rehabilitative techniques, which are aimed at the restoration of the visual function in low vision (LV) patients affected by degenerative diseases. The non-invasiveness of this methodology and its many positive effects on multiple retinal cell targets have led to the use of ES in patients with ischemic optic neuritis, traumatic optic nerve lesions, retinitis pigmentosa (RP), cone-rod dystrophy, Best disease, Stargardt disease, retinal vascular occlusions, glaucoma, and dry and wet ag...

In this study, the number of sensory neurons in the human JG was investigated. And, the morphology of sensory neurons in the human JG and nodose ganglion (NG) was compared. The estimated number of JG neurons was 2721.8-9301.1 (average number of sensory neurons ± S.D. = 7975.1 ± 3312.8). There was no significant difference in sizes of the neuronal cell body and nucleus within the JG (cell body, 1128.8 ± 99.7 μ m2; nucleus, 127.7 ± 20.8 μ m2) and NG (cell body, 963.8 ± 225.7 μ m2; nucleus, 123.2 ± 32.3 μ m2). These findings indicate tha...
