Two patients are described with distinctive clinical features including an insidious onset, slow progression, bilateral ptosis, weakness of facial muscles, dysphagia, muscle atrophy, and weakness with a distal distribution in the extremities, and cardiomopathy with conduction system disorders. Electromyographic studies and muscle biopsy showed features highly suggestive of a myopathic disorder. One case is considered to be sporadic. The other seems to be a familial disorder, because of the presence of a mild atrioventricular block and right incomplete bundle branch block in the patient's son and the presence of eyelid ptosis in his sister. This may be a variant of oculopharyngeal myopathy with distal and cardiomyopathy. It will be necessary to perform long-term follow-up studies in these families.

Thirty-three patients with progressive systemic sclerosis (PSS) (24 women and 9 men, 27 with diffuse scleroderma and 6 with CREST syndrome) were treated with griseofulvin alone (375-500 mg/day) for 12-84 months (mean 33). Clinical and functional assessment of the results included: a self-evaluation (general status, skin toughness, cold sensitivity, dysphagia), a physical examination (fingerprint areas, chest expansion, mouth widening, grip strength) routine laboratory tests, electrocardiogram, glomerular filtration rate (GFR), esophagus and chest X-rays. After griseofulvin, a significant improvement was noted in 28/33 patients (85%) regarding subjective condition and skin thickening and elasticity, particularly in the trunk and proximal limbs (p less than 0.05 for chest expansion), and of GFR (p less than 0.01). Lung and esophageal involvement, on the whole, remained unchanged during the treatment, which does not appear to modify the progression of PSS myocardiopathy. No patient stopped using griseofulvin because of side effects. The present results show that griseofulvin is a safe drug for PSS treatment and that it can influence the skin and renal involvement.

Clinicopathological, immunohistochemical and biochemical studies were performed on seven patients from five families showing an abnormal accumulation of desmin in the muscle fibers. Late onset myopathy was observed in all the cases studied. The clinical features were heterogeneous and usually nonspecific. However, some patients presented with dysphonia, dysphagia or cardiomyopathy. These features are highly suggestive of desmin myopathy. Using electron microscopy, desmin myopathy is characterized by an accumulation of granulofilamentous material. Depending on the distribution of the material, however, three different patterns of desmin accumulation can be observed: (1) large circumscribed inclusions, (2) intermyofibrillar areas of diffusely distributed material, and (3) deposits around large spheroid bodies. The second pattern is characterized by a rubbed-out appearance using oxidative enzyme reactions. For all the patients studied here, the immunohistochemical data showed that the desmin accumulation fitted these three patterns of distribution. For six patients, immunoblot analysis confirmed the desmin accumulation patterns and showed that an increase in the expression of the 53-kDa protein had occurred. The third pattern of desmin accumulation confirms the pathological heterogeneity of cytoplasmic and spheroid bodies. Desmin does not accumulate in all cytoplasmic and spheroid body myopathies, as observed in two other familial cases presented here.

During admission for investigation of dysphagia, an 82-year-old woman suddenly complained of dyspnea, which was followed by cardiogenic shock. Her symptoms, electrocardiogram, echocardiogram and laboratory data were compatible with an extensive acute anterior myocardial infarction. Emergency cardiac catheterization showed no atheromatous narrowing in any coronary artery. However, the contractions of the left and right ventricles were diffusely and severely impaired, except for some hyperkinesis of the basal area. The asynergy, as well as the abnormalities on the ECG, improved almost to normal by the 35th hospital day. An endomyocardial biopsy from the right ventricle during the acute phase showed atypical myocardial damage with proliferation of fine collagen fibers and small round-cell infiltration including polymorphologic leukocytes. This type of transient cardiac disorder has recently been described in Japan, and is called 'Tako-tsubo cardiomyopathy' because of the characteristic appearance of the left ventricular asynergy. In the present case, ventricular asynergy was not limited to the left ventricle, but was also present in the right ventricle.

A 56-year-old woman with a 23 year-history of myotonic dystrophy was admitted to our hospital because of dysphagia and aspiration pneumonia. On admission, patient's ECG showed Ist degree of atrioventricular block and elongation of QRS (133 msec.). On the third hospital day, abnormal Q wave abruptly appeared in aVL associated with elevation of ST segment in V2 and V3, reverse T wave in I, II, III, aVF and V 2-6 leads on ECG. Echo cardiogram demonstrated asynergy at the apex and septal wall. Coronary angiography was normal. Left ventricular ejection fraction determined by left ventriculography decreased to 47.4%. Based on these findings, we thought "stunned myocardium" had developed. Biopsied myocardium from the apex, septum, and free wall showed non-specific findings including mild fibrosis and lymphocytic infiltration. Although overt myocardial disease is rare in myotonic dystrophy, myocardiac disease such as "stunned myocardium" not due to arrhythmia or coronary angiopathy may develop under severe infection, stress, and/or respiratory distress.

Mitochondriopathies (MCPs) are either due to sporadic or inherited mutations in nuclear or mitochondrial DNA located genes (primary MCPs), or due to exogenous factors (secondary MCPs). MCPs usually show a chronic, slowly progressive course and present with multiorgan involvement with varying onset between birth and late adulthood. Although several proteins with signalling, assembling, transport, enzymatic function can be impaired in MCP, most frequently the activity of the respiratory chain (RC) protein complexes is primarily or secondarily affected, leading to impaired oxygen utilization and reduced energy production. MCPs represent a diagnostic challenge because of their wide variation in presentation and course. Systems frequently affected in MCP are the peripheral nervous system (myopathy, polyneuropathy, lactacidosis), brain (leucencephalopathy, calcifications, stroke-like episodes, atrophy with dementia, epilepsy, upper motor neuron signs, ataxia, extrapyramidal manifestations, fatigue), endocrinium (short stature, hyperhidrosis, diabetes, hyperlipidaemia, hypogonadism, amenorrhoea, delayed puberty), heart (impulse generation or conduction defects, cardiomyopathy, left ventricular non-compaction heart failure), eyes (cataract, glaucoma, pigmentary retinopathy, optic atrophy), ears (deafness, tinnitus, peripheral vertigo), guts (dysphagia, vomiting, diarrhoea, hepatopathy, pseudo-obstruction, pancreatitis, pancreas insufficiency), kidney (renal failure, cysts) and bone marrow (sideroblastic anaemia). Apart from well-recognized syndromes, MCP should be considered in any patient with unexplained progressive multisystem disorder. Although there is actually no specific therapy and cure for MCP, many secondary problems require specific treatment. The rapidly increasing understanding of the pathophysiological background of MCPs may further facilitate the diagnostic approach and open perspectives to future, possibly causative therapies.

An 83-year-old woman was admitted to our hospital complaining of respiratory distress. She developed blepharoptosis and dysphagia two months previously. On admission, blood pressure was 150/84 mmHg. There were bilateral blepharoptosis and bulbar palsy. Tendon reflexes were brisk, but pathological reflexes were absent. Repetitive stimulation test demonstrated decrement. Tensilon test was positive. Thus, a diagnosis of myasthenic crisis was made. Vital capacity was 0.71, which necessitated intubation and artificial ventilation. During the first course of immunoadsorption plasmapheresis, blood pressure fell to 80/50 mmHg. ECG showed deeply inverted T waves in leads V2 through V6. Echocardiographic examination demonstrated extensive akinesis around the apex. CK was slightly increased. A diagnosis of "Takotsubo"-shaped cardiomyopathy was made. To maintain blood pressure, dopamine was continuously injected. Left ventricular function returned to normal within a week. No thymoma was seen on the chest CT scan. She was treated with pyridostigmine and tacrolimus. Ten weeks after admission, she was weaned off the ventilator and she had no dysphagia anymore. Anti-acetylcholine receptor antibody titers had decreased. In Japan, approximately 17% of patients with myasthenia gravis are in the seventh decade or older. Approximately 10% of the patients of this age group suffer from severe generalized form. Careful ECG monitoring is necessary while treating elderly patients with myasthenic crisis, because they are at potential risk of developing "Takotsubo"-shaped cardiomyopathy.

The transthyretin Tyr77 variant of familial amyloid polyneuropathy (FAP) has been identified in a few North American and European patients, but the full spectrum of its clinical manifestations is still not known. We report a 3-generation family of Jewish-Yemenite origin with Tyr77 FAP presenting with atypical features. The affected individuals had sensorimotor and autonomic neuropathy and cardiomyopathy accompanied by prominent dysphagia, hearing loss and asymptomatic carpal tunnel syndrome. Brain MRI in the proband showed multifocal white matter lesions. These features extend the reported Tyr77 phenotype and support the modifying effect of additional factors on the disease expression.

Polysaccharide myopathy is a rare form of storage muscular disorder. The clinical picture of this particular form of myopathy is unspecific. We report a 62-year-old woman with late-onset progressive weakness and wasting, affecting proximal muscles of the four limbs and the girdles. No myalgia, dysphagia nor symptoms of cardiac failure were observed. Muscle biopsy revealed a vacuolar myopathy with accumulation of amylopectin-like polysaccharide. This material was strongly PAS-positive and diastase-resistant. At electron microscopy, the deposits were composed of non-membrane-bound filamentous and granular material surrounded by numerous mitochondria. No enzyme deficiency was found. Clinical presentation of our patient was similar to the 16 cases reported in the literature. She did not have myocardiopathy and her survival is much longer. Hypothetic mechanisms of polysaccharide accumulation are reviewed.
