Apoplexy of the heart can be responsible for sudden and for recurring instability of cardiac rhythm and conduction, and for the clinical counterparts of syncope and sudden death. Every pathophysiological mechanism which produces cerebral apoplexy has its counterpart in apoplexy of the heart. Among the mechanisms documented are thrombosis, embolism and rupture of those special vessels supplying the sinus node, atrioventicular (A-V) node and His bundle. Apoplexy of the heart can occur either with or without significant or recognizable ventricular myocardial infarction. Acute vascular accidents within the critical centers of cardiac impulse formation and conduction deserve more frequent consideration in the explanation of unusual cases of "epilepsy", of seizure disorders of the elderly, of neurologic manifestations (which may be secondary as well as primary) of systemic diseases such as lupus erythematosus or thrombotic thrombocytopenic purpura, and indeed of every case of otherwise unexplanined syncope or sudded death at any age.

We reported 9 cases of primary Sjogren syndrome (SS) who were complicated with nervous system involvement. All were women. Age between 24 to 58 years old. Their clinical symptoms of the nervous system varied widely, 7 of them manifested with the involvement of central nervous system, the main features were in case 1 bouts of seizures, case 2 multi-level damage of the brain and spinal cord which was similar to multiple sclerosis, case 3 recurrent hemiplegia caused by cerebral thrombosis then fatal vascular hemorrhage, case 4 sudden hemiplegia, case 5 persistent psychological disturbance, case 6 cranial neuropathy of V and VII, case 9 multi-focal symptoms of ataxia, myelopathy and transient blindness. 5 of the 9, case 3, 6-9 all appeared with the symptoms of peripheral neuropathy, case 7 also complicated with carpal tunnel syndrome. 4 of the 9 cases also complicated with renal tubular acidosis and/or chronic active hepatitis and/or fibrosing alveolitis and/or thrombocytopenic purpura and/or myositis. No differences of the positivity of autoantibodies was observed between those with or without nervous system involvement.

Of 40 patients with thrombotic thrombocytopenic purpura, 17 were treated with plasma exchange, 15 with exchange transfusions, and 6 with both types of therapy. One patient died before being treated and another patient was seen but not treated. Plasma exchange was performed daily for a mean of seven exchanges per patient. The replacement fluid during plasma exchange was fresh frozen plasma in all cases. The complete response rates for each type of treatment were as follows: 88% for plasma exchange (15 patients), 47% for exchange transfusions (7 patients), and 67% for exchange transfusions and plasma exchange (4 patients). Clinical and laboratory factors were examined for any statistically significant association with therapy response. Treatment with plasma exchange was statistically the initial factor most strongly associated with prognosis. Paresis, paresthesias, seizures, mental status change, and coma showed no association with response to treatment. Some of the laboratory factors that did not show significant association with treatment response were the initial creatinine, hemoglobin, platelet count, lactate dehydrogenase, and total bilirubin. This study supports the hypothesis that plasma exchange has significantly improved the prognosis of patients with thrombotic thrombocytopenic purpura. These patients should be treated aggressively regardless of the severity of their symptoms.

A patient with metastatic gastric adenocarcinoma had progressive microangiopathic red blood cell changes, thrombocytopenia with increased marrow megakaryocytes, bleeding, altered mentation, and seizure. Coagulation parameters were inconsistent with disseminated intravascular coagulation; a clinical diagnosis of thrombotic thrombocytopenic purpura (TTP) was made. Plasmapheresis resulted in improvement on two separate occasions. The diagnosis of tumor-associated TTP should be considered in cancer patients. Plasmapheresis may be more effective than plasma transfusion alone in this syndrome, perhaps via removal of tumor-induced immune complexes from the circulation. Aggressive management of this complication seems justified in cancer patients for whom effective chemotherapy exists.

A 60-yr-old female presented with typical thrombotic thrombocytopenic purpura (TTP). She remained in coma with frequent seizures for 1 wk, with persisting severe thrombocytopenia and microangiopathic haemolytic anaemia, despite treatment with prednisolone, plasma exchange, fresh frozen plasma, sulphinpyrazone and dipyridamole. Splenectomy induced haematological improvement within 1 d, there was cessation of fitting after 2 d, and full neurological recovery ensued over 3 wk. Laboratory studies did not reveal the presence of a platelet-aggregating factor (PAF), stated to be present in some two-thirds of cases. While plasma exchange and plasma infusion are beneficial in many cases, splenectomy appears still to be of value in unresponsive disease.

Two patients with well documented systemic lupus erythematosus developed a syndrome resembling thrombotic thrombocytopenic purpura. Both had severe thrombocytopenia, microangiopathic hemolytic anemia, seizures, and renal dysfunction. Prothrombin time, partial thromboplastin time, thrombin time, and fibrinogen levels were normal; fibrin degradation products were minimally elevated. Histologic evaluation of renal biopsies in both patients confirmed the impression of intravascular thrombosis. Therapy with corticosteroids, other immunosuppressive drugs and splenectomy (in one case) proved unsuccessful. The infusion of fresh frozen plasma, with or without plasmapheresis, reversed the syndrome. This report indicates that patients with systemic lupus may develop a thrombotic thrombocytopenic purpura like syndrome which responds to fresh plasma infusion.

Vagus nerve stimulation (VNS) has demonstrated a significant anticonvulsant effect in preclinical studies, in pilot studies in humans, and in the acute phase of a multicenter, double-blinded, randomized study. After completion of a 14-week, blinded, randomized study, with 31 receiving high (therapeutic) VNS and 36 receiving low (less or noneffective) VNS, 67 patients elected to continue in an open extension phase. During the extension phase, all 67 patients received high VNS. Seizure frequency during the 3-month treatment blocks was compared with a 12-week baseline. For both groups, all periods of high VNS demonstrated a significant decrease in seizure frequency (p < 0.01 level) as compared with baseline. For the 16-18-month period of VNS, data were available for 26 of the 31 patients randomized to high VNS. This group achieved a 52.0% mean seizure frequency percentage reduction as compared with baseline. For those converted from low to high VNS, data were available for 24 of the 36 patients at the 16-18-month time period. This group reported a mean seizure frequency percentage reduction of 38.1% as compared with baseline. No significant change in the safety/side effect profile was reported during long-term follow-up. The previously reported side effects of hoarseness/voice change, coughing, and paresthesia (sensation in neck and jaw) continued to occur during VNS. These side effects were well tolerated. During the follow-up period, 1 patient died of thrombotic thrombocytopenic purpura (TTP) and 5 patients discontinued treatment because of unsatisfactory efficacy.

A 78-year-old woman was admitted to our hospital because of disorientation and fever on January 21, 1992. Two days before admission she experienced vomiting, anorexia and general malaise. Laboratory examinations on admission disclosed a hemoglobin level of 11.1 g/dl and a platelet count of 8,000/microliters. The peripheral blood smear revealed anisocytosis with numerous schistocytes and poikilocytes. Polychromatophilic and nucleated red blood cells were also seen, and the reticulocyte count was 38/1000. Her serum lactate dehydrogenase (LDH) value was 2,977 WU and the total serum bilirubin level was 3.5 mg/dl with 2.7 mg/dl indirect reacting fraction. Serum creatinine was 4.7 mg/dl. Her consciousness became semicomatose after a systemic seizure which lasted approximately 15 seconds and her hemoglobin level decreased to 8.5 g/dl on hospital day 2. Therefore, we diagnosed her as having thrombotic thrombocytopenic purpura (TTP) because of the presence of all 5 features, that is, thrombocytopenia, microangiopathic hemolytic anemia, fluctuating neurologic abnormalities, renal dysfunction and fever. A plasmapheresis with fresh frozen plasma (FFP) replacement was begun on that day. She was also treated with anti-platelet agents, 80 mg/day aspirin, and 300 mg/day dipyridamole. Moreover, packed red blood cells (PRC) were infused. While also receiving diphenylhydantoin and phenobarbital to prevent convulsions, status epilepticus developed on day 3. Because of inhibited spontaneous respiration which was an adverse effect derived from diazepam and sodium thiamylal administered intravenously to treat the status epilepticus, an artificial respiration was initiated.(ABSTRACT TRUNCATED AT 250 WORDS)

We report the case of a 70 years old woman who developed a thrombotic thrombocytopenic purpura. Despite a treatment with corticoids and high doses IV gammaglobulins, the patient developed seizures. Treatment with plasma exchanges combined with plasma infusions allowed recovery. The authors review the clinical and biological aspects as well as the pathogeny of the disease. The authors insist on the importance of the plasma exchanges in the treatment of this disease.
