Evidence for a relatively high proportion of DM2 mutations in a large group of Polish patients.

Introduction: Myotonic dystrophies (DMs) type 1 (DM1) and type 2 (DM2) are autosomal dominant, multisystem disorders, considered the most common dystrophies in adults. DM1 and DM2 are caused by dynamic mutations in the DMPK and CNBP genes, respectively.

Methods: Molecular analyses were performed by PCR and the modified RP-PCR in patients, in their at-risk relatives and prenatal cases.

Changing phenotypic expression in a patient with a mitochondrial encephalopathy due to 13042G>A de novo mutation--a 5 year follow up.

Mutations in NADH dehydrogenase (ND) subunits of complex I lead to mitochondrial encephalomyopathies associated with various phenotypes. This report aims to present the patient's clinical symptomatology in the context of a very rare 13042G>A de novo mutation and with an emphasis on changing phenotypic expression and pronounced, long-standing response to levetiracetam.

The N-terminal pro-brain natriuretic peptide as a marker of mitoxantrone-induced cardiotoxicity in multiple sclerosis patients.

Background And Purpose: Mitoxantrone (MTX) has been shown to reduce progression of disability and number of clinical exacerbations in patients with progressive multiple sclerosis (MS). Prolonged administration of MTX, however, is limited by the risk of cardiotoxicity. Cardiac monitoring in MTX-treated patients includes usually measurement of left ventricular ejection fraction (LVEF) by means of echocardiography.

Mitochondrial encephalomyopathy: towards diagnosis. A case report.

Mitochondrial diseases may cause a wide range of central and peripheral nervous system disorders, as well as muscle disorders. The diagnostic workup routinely includes electrophysiological, morphological, neuroimaging and genetic studies. In some cases, the diagnosis may be ascertained only when mitochondrial DNA (mtDNA) examination in the muscle is performed.
