Myasthenia gravis with thymoma and autoimmune haemolytic anaemia. A case report.

Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction and leads to weakness of the skeletal muscles. Associated autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis and pernicious anaemia are present in approximately 5% of the myasthenic patients. This report presents a 64-year-old man with autoimmune haemolytic anemia associated with myasthenia gravis and thymoma. The patient developed a severe Coomb's positive autoimmune haemolytic anaemia, which was resistant to treatment with large doses of prednisone. Haemolytic anaemia entered remission one month following thymectomy, and the patient has maintained a normal haemoglobin and a negative Coomb's test without the need for steroid or immunosuppressive therapy. In conclusion, thymectomy may induce a striking improvement of therapyresistant autoimmune haemolytic anemia in patients with MG and thymoma, but in terms of remission, a long follow-up is needed as autoimmune diseases can show spontaneous fluctuations.

Intraarterial Thrombolysis with r-tPA for Treatment of Anterior Circulation Acute Ischemic Stroke. Technical and Clinical Results.

SUMMARY: To investigate factors effecting the safety and recanalization efficacy of local intraarterial (IA) recombinant tissue plasminogen activator (r-tPA) delivery in patients with acute ischemic stroke. Eleven patients with anterior circulation acute ischemic stroke were treated. The neurological status of the patients were graded with the Glasgow Coma Scale (GCS) and National Institute of Health Stroke Scale (NIHSS). All patients underwent a computed tomography (CT) examination at admission. In addition four patients had diffusion-weighted and one patient had a perfusion magnetic resonance (MR) examinations. Patients were treated within six hours from stroke onset. Immediate, six hours, and 24 hours follow-up CT examinations were performed in order to evaluate the haemorrhagic complications and the extent of the ischemic area. The Rankin Scale (RS) was used as an outcome measure. Two of the 11 patients had carotid "T" occlusion (CTO), nine had middle cerebral artery (MCA) main trunk occlusion. Four patients had symptomatic haemorrhage with a large haematoma rupturing into the ventricles and subarachnoid space. Of these, three patients died within 24 hours. The remaining seven patients had asymptomatic haematomas that were smaller compared to symptomatic ones, and showed regression in size and density on follow-up CTs. At third month five patients had a good outcome and three patients had a poor outcome. In acute ischemic stroke, local IA thrombolysis is a feasible treatment when you select the right patient. Haemorrhage rate does not seem to exceed that occuring in the natural history of the disease and in other treatment modalities.
