    Myopathy and hypertrophic cardiomyopathy with selective lysis of thick filaments (1993)
    Springer

    Notes: Abstract We present a undescribed condition in a girl who died at 8 years of hypertrophic cardiomyopathy. Muscle and endomyocardial biopsies disclosed a selective loss of thick filaments ultrastructurally. In muscle biopsy histochemical abnormalities of myofibrillar AT-Pase were confined to type 1 fibres. Gel electrophoresis of muscle homogenate showed no qualitative abnormalities of slow and fast myosin heavy chains (MHC) and light chains, and the amount of the different myosin isozymes was in agreement with histochemical myofibrillar ATPase findings. The pathogenetic mechanisms have not been elucidated in this case but we suspect an abnormality of theβ-cardiac MHC gene, the only gene expressed in the heart and in type 1 skeletal muscle fibres.

    Autosomal recessive hypermyelinating neuropathy (1994)

    Notes: Abstract. We studied three patients from two kinships, affected by early onset hereditary motor and sensory neuropathy with probable autosomal recessive inheritance (HMSN type III). Morphological studies of sural nerve biopsies revealed an abnormal myelin proliferation. Two adult patients with long-term follow up, lost ability to walk at 28 and 22 years and showed severe involvement of the cranial nerves. Our observations suggest that "hypermyelination neuropathy" with early onset is a progressive disease with poor long-term prognosis. In one kinship the occurrence of the disease in two sibs of both sexes but not in parents, is consistent with an autosomal recessive inheritance. Familial cases of hypermyelination neuropathy have not been described in previous reports. Morphological aspects of this condition are compared with other forms of hypermyelination neuropathy.

    Reducing body myopathy and desmin storage in skeletal muscle: morphological and biochemical findings (1994)

    Notes: Abstract. We describe clinical, morphological and biochemical findings of a patient with reducing body myopathy (RBM). This 15-year-old patient was affected by severe limb-girdle progressive myopathy with asymmetric distribution. Muscle biopsy showed many fibers with cytoplasmic polymorphic masses, which stained dark purple with modified Gomori's trichrome, associated with proliferation of cytoplasmic bodies. Cytoplasmic polymorphic masses showed marked reducing activity with menadione-nitro blue tetrazolium reaction. Ultrastructurally, there was great amount of highly electron-dense tubular-filamentous structures of 16 – 17 nm in diameter. Immunohistochemistry showed that many fibers were positive for desmin. Sodium dodecyl sulfate-electrophoresis disclosed an increase in two bands of approximately 53 and 70 kDa, and Western blot demonstrated that the 53-kDa band was desmin. It was not possible to characterize the 70-kDa protein further.

    Notes: Summary The clinical, morphological and biochemical findings of a sporadic case, showing accumulation of desmin-type intermediate filaments in skeletal muscle and myocardium are described. Desmin storage was demonstrated by immunofluorescence, sodium dodecyl sulfate gel electrophoresis and two-dimensional gel electrophoresis. These findings are in agreement with those of Rappaport et al. (FEBS Lett. 231:421–425, 1989). A sensory-motor polyneuropathy was established by electrophysiological studies and, ultrastructurally, intramuscular nerves showed accumulation of neurofilaments and neurotubules with formation of axonal spheroids. These findings are discussed considering all previous reports with related conditions.

    Notes: Summary We report on a 5 1/2 year-old boy with chronic progressive polynèuropathy, ataxia, and pyramidal signs. His hair was not curled. Sural nerve biopsy disclosed many axons enlarged by accumulation of 10-nm neurofilaments and a marked variability in the number of myelinated fibers as well as in the amount of axonal enlargements among different fascicles. These findings and the electrophysiological data were consistent with a giant axonal polyneuropathy with a multifocal fiber loss.

    Chromosome 4q35 haplotypes and DNA rearrangements segregating in affected subjects of 19 Italian families with facioscapulohumeral musculatur dystrophy (FSHD) (1994)

    Notes: Abstract Four DNA markers on the distal long arm of chromosome 4 have been analyzed for their linkage to facioscapulohumeral muscular dystrophy locus (FSHD) in a series of 16 Italian families. We found that, in two families, the disease is not linked to the 4q35 markers, indicating the presence of genetic heterogeneity among Italian FSHD families. Linkage analysis in the remaining families supports the order cen-D4S171-D4S163-D4S139-D4S810-FSHD-qter, in agreement with the physical map from the literature. EcoRI digestion and hybridization with the distal marker p13E-11 (D4S810) The locus D4S810 corresponding to probe p13E-11 has been recently renamed D4F104S1. detected DNA rearrangements in the affected members of both sporadic and familial cases of FSHD, with family-specific fragments ranging in size between 15 kb and 28 kb. In three sporadic FSHD cases, the appearance of a new “small” fragment not present in either parent was clearly associated with the development of FSHD disease. However, in the familial cases analyzed, we observed two recombinations between all four 4q35 markers and the disease locus in apparently normal subjects, leaving open the possibility of nonpenetrance of the FSHD mutation.

    Notes: Abstract A girl affected by a restrictive cardiomyopathy with neuromuscular involvement is described. Morphological examination showed a pattern of multicore myopathy and with electron microscopy a sarcoplasmic accumulation of electron dense granular and filamentous material was demonstrated both in skeletal muscle and heart. This peculiar electron dense material corresponded to increased desmin in muscle and cardiac fibres and was demonstrated immunohistochemically.
