Twenty-one patients with polymyositis were prospectively examined with echocardiography, phonocardiography and electrocardiography. Cardiac performance, estimated with echocardiography, was enhanced as shown by a significant (P less than 0.01) increase in ejection phase indexes of left ventricular function compared with values in a matched control group. Known causes of the high output state, such as anemia or thyrotoxicosis, were not clinically evident. There was no evidence of left ventricular enlargement, left ventricular wall hypertrophy, or left atrial enlargement in the echocardiogram or chest X-ray film. The echocardiogram showed systolic mitral valve prolapse in 11 of 17 patients (65 percent) with an adequately imaged mitral valve; midsystolic clicks were present in 7 of these. One patient, who did not have prolapse, had echocardiographic evidence of a small pericardial effusion. Electrocardiographic abnormalities were present in 11 of 21 patients (52 percent) and included evidence of atrioventricular conduction disturbances, atrial and ventricular arrhythmias and left atrial abnormality. The pathophysiology of mitral valve prolapse and increased systolic left ventricular function in polymyositis remains uncertain; however, the spectrum of cardiac abnormalities, detected noninvasively in 16 of 21 of our patients (76 percent) may represent a high frequency rate of cardiac involvement in this disease.

Fourteen patients with polymyositis-dermatomyositis (PM-DM) underwent prospective cardiac assessment with non-invasive techniques. One patient had electrocardiographic evidence of Long-Ganong-Levine syndrome with multiple supraventricular premature beats. Echocardiographically one patient had late systolic prolapse of the posterior mitral leaflet and another had paradoxical movements of the interventricular septum. The study suggests that cardiac involvement is infrequent in PM-DM.

Myasthenia-like symptoms and Eaton-Lambert myasthenic syndrome have been reported in patients with polymyositis. On the other hand, the muscular involvement in myasthenic patients is well established. Thus difficulties in the differentiation of patients with polymyositis and myasthenic syndrome and myasthenia with myopathy may arise. The aim of this investigation was to re-establish the clues for distinguishing between different types of myasthenic syndromes. One hundred and twenty five patients took part in this investigation. According to the electromyography, biopsy and serum levels of creatine kinase data, the patients were subdivided into three groups. The first group consisted of 35 patients with data for chronic polymyositis. The second group consisted of 46 patients with myasthenia. The third group consisted of 44 patients with myasthenia and myopathy. Our data confirm the more often onset of myasthenia with ptosis and of myasthenic syndromes in polymyositis-from lower limbs. The bulbar involvement is more rare, while the autonomic nervous system involvement and decreased tendon reflexes are more common in patients with Eaton-Lambert myasthenic syndrome as compared to patients with myasthenia. Bulbar involvement is more typical for myasthenia, while four limbs involvement is more common in patients with myasthenia and myopathic changes. There are no differences in the typical decrementing response between patients with polymyositis, myasthenia or myasthenia with myopathic involvement. The Eaton-Lambert myasthenic syndrome is quite different and is found only in a small part of polymyositis patients. In conclusion the differential diagnosis between myasthenic syndromes in polymyositis and myasthenia with muscular involvement is not possible only by electromyography.

We report a patient of polymyositis and myasthenia gravis as manifestations of chronic graft-versus-hot disease (GVHD). A 48-year-old man was diagnosed as having chronic myelogenous leukemia at the age of 42 years, and had bone marrow transplantation (BMT) two years after the onset of the disease. Since he suffered from mild liver dysfunction and cutaneous involvement manifesting chronic GVHD, he was placed on prednisolone and cyclophosphamide. As his condition improved, the prednisolone was gradually tapered. Forty-one months after the BMT, the patient developed muscle pain and muscle weakness. A diagnosis of polymyositis was made from muscle biopsy and laboratory findings. An increase in the prednisolone dose was effective but a few weeks later the patient noticed ptosis and recurrence of muscle weakness. A tensilon test and anti-acetylcholine receptor antibody produced positive results, leading to a diagnosis of myasthenia gravis. Only one case of polymyositis and myasthenia gravis as manifestations of chronic GVHD has been reported, and in our patient both symptoms appeared almost at the same time. Although neuromuscular symptoms as a manifestation of chronic GVHD are rare, all patients receiving BMT should be carefully followed up neurologically to detect neuromuscular complications.

A 58-year-old man presented with diplopia and partial ptosis for 10 years. It was non-progressive in nature, despite inadequate medical attention the patient received from non-specialists/general practitioners. He did not have fatigability or diurnal variation in weakness and was clinically stable without exacerbations of disease for a decade. He did not have features of Graves's disease, oculopharyngeal dystrophy, cranial nerve paralysis, polymyositis and stroke. The possibility of an atypical presentation of myasthenia gravis (MG) was considered and the patient was evaluated. Ice pack test was negative, Cogan's lid twitch (CLT) test was positive and high titres of acetylcholine receptor antibodies (AChR Ab) suggestive of MG were found. He was treated accordingly with a very good response.
