The Cognitive Decline of Marshal Philippe Pétain.

In 1940, at the age of 84, Marshal Pétain was appointed the head of state and government of France. His health was excellent but he tired easily. He felt unable to learn and his memory was weak.

A short history of the notion of neurodegenerative disease.

The notion of heredity of degenerative constitutions of human beings contributed in the nineteenth century to the fear for deterioration of the human race and in the twentieth century to attempts by several Western Countries, particularly Germany, to improve the inborn qualities of their populations by eugenic measures. In the years following World War II, the term eugenics was eradicated from medicine. The qualification degenerative disappeared from genetics and psychiatry but remained in use to denote decay of tissues and cells.

Rembrandt's 'Beggar with a wooden leg' and other comparable prints.

Rembrandt's etching of a beggar with a wooden leg is notable because the two lower limbs of the presumed beggar are present and not deformed. Using the facilities of four specialised Dutch art institutes, we carried out a systematic investigation to find other etchings and engravings of subjects with artificial legs supporting non-amputated limbs, from the period 1500 to 1700 AD. We discovered 28 prints produced by at least 18 artists.

Vinken and Bruyn's Handbook of Clinical Neurology. A witness of late-twentieth century neurological progress.

Vinken and Bruyn's Handbook of Clinical Neurology (HCN) is best characterized as an encyclopedia. In this paper we describe the origin, production, and reception of HCN. Data were gathered from a literature search, by screening of HCN-volumes, interviewing key-role persons and a study of an HCN-archive.

[The practice guideline 'Dermatomyositis, polymyositis and sporadic inclusion body myositis'].

This guideline presents recommendations for the diagnosis and treatment of dermatomyositis, polymyositis and sporadic inclusion body myositis (sIBM) according to the best available evidence. Characteristic skin abnormalities can be sufficient for the diagnosis of dermatomyositis. In case of doubt, a skin biopsy is advisable.

[The symptomatic treatment of amyotrophic lateral sclerosis].

Patients with amyotrophic lateral sclerosis (ALS) have symptoms of progressive muscle weakness, of disturbed speech and swallowing, and in the terminal phase those of respiratory weakness. Treatment options, in particular those for excessive weight loss and respiratory weakness, should be introduced to the patients and their families when the patient is emotionally capable and before dysarthria severely hampers communication. Special equipment for keeping the patient as mobile as possible should be made available much earlier than in the case of other diseases of the muscles as in ALS progression is much faster.

[Amyotrophic lateral sclerosis: mechanical ventilation--or not right?].

In two patients (men aged 64 and 62 years, respectively) with amyotrophic lateral sclerosis (ALS) tracheostomy ventilation was initiated following (imminent) acute respiratory failure; in one patient this was done because advance directives were lacking, while in the other non-invasive ventilation (NIPPV) was no longer an option. A third ALS patient, a woman aged 36 years, already had chronic respiratory failure when she presented at the local centre for home mechanical ventilation. As a result, the placement of a percutaneous endoscopic gastrostomy (PEG) was impossible.

Age-related changes in human thyroarytenoid muscles: a histological and histochemical study.

We examined the thyroarytenoid muscles of 23 larynges in order to assess function-related characteristics and to discover age-related changes. The neonatal thyroarytenoid muscle differed from limb muscles in the slow maturation of fibre types. In adults, we examined the medial part of the thyroarytenoid muscle.

The central nervous system in systemic lupus erythematosus. Part 2. Pathogenetic mechanisms of clinical syndromes: a literature investigation.

Objectives: To identify the pathogenetic mechanisms of central nervous system (CNS) syndromes of systemic lupus erythematosus (SLE) as described in the literature.

Methods: Using PUBMED, we performed a systematic search of publications from 1980 onwards. Studies were eligible if they had been performed on patients or material from patients with CNS manifestations and definite SLE and when the CNS manifestations were not secondary.

The central nervous system in systemic lupus erythematosus. Part 1. Clinical syndromes: a literature investigation.

Objectives: To establish the central nervous system (CNS) manifestations of systemic lupus erythematosus (SLE) as described in the literature and to compare the results with two previously published classifications.

Methods: Using PUBMED, a systematic search was performed for publications from 1980 onwards on CNS syndromes of patients with SLE. A distinction was made between CNS syndromes induced by SLE and the CNS autoimmune diseases associated with SLE.

Comparison of weakness progression in inclusion body myositis during treatment with methotrexate or placebo.

We investigated whether 5 to 20mg per week oral methotrexate could slow down disease progression in 44 patients with inclusion body myositis in a randomized double-blind placebo-controlled study over 48 weeks. Mean change of quantitative muscle strength testing sum scores was the primary study outcome measure. Quantitative muscle strength testing sum scores declined in both treatment groups, -0.

Diagnostic and classification criteria for the Guillain-Barré syndrome.

Background: Diagnostic criteria for the Guillain-Barré syndrome (GBS) have been available since 1978. Since then, several variants have been described. More recently, a distinction has been made between pure motor forms, severe sensory forms, primary axonal and primary demyelinating varieties.

Epidemiology of inclusion body myositis in the Netherlands: a nationwide study.

Epidemiologic data on inclusion body myositis (IBM) are scarce, and possibly biased, because they are derived from larger neuromuscular centers. The present nationwide collaborative cross-sectional study, which culminated on July 1, 1999, resulted in identification of 76 patients with IBM and the establishment of a prevalence of 4.9 patients with IBM per million inhabitants in the Netherlands.

A novel gamma-sarcoglycan mutation causing childhood onset, slowly progressive limb girdle muscular dystrophy.

Limb girdle muscular dystrophy is a heterogeneous group of disorders. One autosomal recessive subtype, LGMD2C, has been linked to chromosome 13, and is caused by gamma-sarcoglycan deficiency in muscle. This report describes a novel missense mutation identified in a large consanguineous Dutch family with LGMD.

The heart in limb girdle muscular dystrophy.

Objective: To assess the frequency, nature, and severity of cardiac abnormalities in limb girdle muscular dystrophy, and its relation to age and weakness in various genotypes.

Design: In 26 autosomal dominant, 38 autosomal recessive, and 33 sporadic strictly defined patients with limb girdle muscular dystrophy, cardiac evaluation included history, physical examination, chest x ray, electrocardiography, 24 hour ECG Holter monitoring, and echocardiography. In 35 of the 71 autosomal recessive and sporadic cases muscle biopsies were available for sarcoglycan analysis.

[Peer review in requests for subsidy].

There is peer review by scientific journals and by fund granting institutions. The former is usually a very thorough procedure with the authors being informed of the reasons for rejection of the article, whereas the latter often leaves the applicants with doubts as to the thoroughness and the fairness of the procedure. It is suggested that grant peer review follow the rules for scientific journal peer review including information of the applicants of the referees' findings and opinions.

Intermittent cyclophosphamide and prednisone treatment of polyneuropathy associated with monoclonal gammopathy of undetermined significance.

In an open prospective study, we analyzed the effect of cyclophosphamide (300 mg/m2 body surface daily for 4 days) combined with prednisone (40 mg/m2 body surface daily for 5 days) at 4-week intervals during 6 months in 16 patients with polyneuropathy associated with monoclonal gammopathy of undetermined significance (MGUS). Eleven patients had an IgM-MGUS and five an IgG-MGUS. During a follow-up period of 3 years, eight patients had improvement and six patients stabilized, based on quantitative neurologic examination, the Rankin disability scale, and electrophysiologic studies.

The clinical spectrum of limb girdle muscular dystrophy. A survey in The Netherlands.

A cross-sectional study was performed in the Netherlands to define the clinical characteristics of the various subtypes within the broad and heterogeneous entity of limb girdle muscular dystrophy (LGMD). An attempt was made to include all known cases of LGMD in the Netherlands. Out of the reported 200 patients, 105 who fulfilled strictly defined criteria were included.

Two divergent types of nerve pathology in patients with different P0 mutations in Charcot-Marie-Tooth disease.

In seven unrelated patients with a demyelinating motor and sensory neuropathy, we found mutations in exons 2 and 3 of the P0 gene. Morphologic examination of sural nerve biopsy specimens showed a demyelinating process with onion bulb formation in all cases. In four patients, ultrastructural examination demonstrated uncompacted myelin in 23 to 68% of the myelinated fibers, which is in agreement with the widely accepted function of P0 as a homophilic adhesion molecule.

Effects of ciliary neurotrophic factor on retrograde cell reaction after facial nerve crush in young adult rats.

Locally applied ciliary neurotrophic factor (CNTF) has a powerful effect on retrograde axonal reaction following facial nerve crush in neonatal rats. We examined whether it also exerts a strong effect on retrograde axonal reaction in young adult rats when administered subcutaneously. The dose was 1 mg/kg body weight, three times a week, similar to that used in a previous experiment in which CNTF was reported to have an effect.

Genetic heterogeneity of hereditary motor and sensory neuropathy type VI.

Charcot-Marie-Tooth disease comprises a heterogeneous group of neurologic disorders that shape peripheral motor and sensory neuropathy. A classification of these disorders was proposed in 1975, defining seven types of hereditary motor and sensory neuropathy. Clinical features of hereditary motor and sensory neuropathy type VI are muscle weakness and atrophy in leg and hand muscles, leading to progressive disability and loss of vision and progressing to blindness due to optic atrophy.
