Lewis-Sumner syndrome (LSS) is a dysimmune peripheral nerve disorder, characterized by a predominantly distal, asymmetric weakness mostly affecting the upper limbs with sensory impairment, and by the presence of multifocal persistent conduction blocks. The nosological position of this neuropathy in relation to multifocal motor neuropathy (MMN) and chronic(More)
Sporadic inclusion body myositis (s-IBM) is characterized histologically by the association of concomitant inflammatory and degenerative processes. We evaluated the sensitivity and specificity of different markers of the degenerative process in order to refine the histological diagnosis. We performed an immunohistochemical study with antibodies directed(More)
BACKGROUND Neuropathies associated with lymphoma (NAL) are rare and present a great clinical heterogeneity, making them difficult to diagnose and worsening their prognosis. OBJECTIVES (1) To report the different patterns of NAL and discuss the mechanisms encountered; (2) to determine the relationship between a given type of lymphoma and a specific type of(More)
Patients with cervical or mediastinal Hodgkin disease (HD) classically underwent chemotherapy plus extended-field radiation therapy. We report six patients who gradually developed severe atrophy and weakness of cervical paraspinal and shoulder girdle muscles 5-30 years after mantle irradiation for HD. Although clinical presentation was uniform, including a(More)
Miyoshi myopathy is the most common form of recessive distal myopathy. Recessive mutations in the ANO5 gene have been recently identified in Northern Europe as a cause of non dysferlin-linked distal myopathy and limb girdle muscular dystrophy. We report here the first French cases of anoctamin 5 myopathy in 2 brothers presenting with a Miyoshi-like pattern.(More)
Congenital myasthenic syndromes (CMS) are a heterogeneous group of disorders caused by genetic defects affecting neuromuscular transmission and leading to muscle weakness accentuated by exertion. Three different aspects have been investigated by members of the national French CMS Network: the difficulties in making a proper diagnosis; the course and(More)
Myofibrillar myopathies (MFM) have been described in the mid-1990s as a group of diseases sharing common histological features, including an abnormal accumulation of intrasarcoplasmic proteins, the presence of vacuoles and a disorganization of the intermyofibrillar network beginning at the Z-disk. The boundaries of this concept are still uncertain, and(More)
OBJECTIVE In this study we aim to demonstrate the occurrence of adult forms of TK2 mutations causing progressive mitochondrial myopathy with significant muscle mitochondrial DNA (mtDNA) depletion. METHODS Patients' investigations included serum creatine kinase, blood lactate, electromyographic, echocardiographic, and functional respiratory analyses as(More)
BACKGROUND AND PURPOSE Our aim was to determine the prognostic value of urine and blood heteroplasmy in patients with the m.3243A>G mutation. METHODS Adults with the m.3243A>G mutation referred to our institution between January 2000 and May 2014 were retrospectively included. The relationship between their baseline clinical characteristics, their(More)
