A fatal case of Behçet's disease associated with multiple cardiovascular lesions.

Behçet's disease is recognised as a chronic multisystem disorder with vasculitis as its underlying pathological process. Cardiac involvement is rare and often associated with poor prognosis. A large right atrial thrombus, pulmonary aneurysms and aortic pseudoaneurysm that developed 17 years after surgery for bilateral renal artery stenosis is presented in a 26-year-old Behçet's disease patient. He was admitted to the hospital with fever of unknown origin associated with chest pain, dyspnea, cough, haemoptysis and pulmonary opacity in chest X-ray. Initial pulmonary CT demonstrated small subpleural infiltrates bilaterally, one of which was round and suspected as being metastatic. Examination of open lung biopsy demonstrated haemorrhagic infarct surrounded by some occluded pulmonary arteries. Subsequent CT showed pulmonary aneurysms compatible with Behçet's disease. Echocardiography demonstrated a large pedunculated mass in the right atrium. Injection of urographin showed a right atrial mass and a large right pulmonary artery aneurysm. The atrial mass was completely excised during open heart surgery and was identified as being an organising thrombus. Eight weeks later while taking prednisone, he was readmitted because of an infected mid sternal wound. CT showed slight separation of the stemum, retrosternal fluid, pulmonary arteries aneurysm and ascending aorta aneurysm. The next day, the patient died from massive bleeding from his ruptured ascending aortic pseudoaneurysm. Bizarre presentation of arterial and venous thromboses or arterial aneurysm formation, particularly in young patients, should suggest Behçet's disease.

Cardiac valvular vegetations in cancer patients: a prospective echocardiographic study of 200 patients.

PURPOSE: Nonbacterial thrombotic endocarditis can complicate various malignancies and may cause morbidity and mortality mainly as a result of systemic embolism. The antemortem diagnosis of nonbacterial thrombotic endocarditis is rare. The purpose of our study was to assess the frequency, echocardiographic characteristics, and clinical correlation of nonbacterial thrombotic endocarditis in cancer patients. PATIENTS AND METHODS: A prospective echocardiographic screening of 200 nonselected ambulatory patients with solid tumors was performed. Patients were evaluated for evidence of thromboembolic events and for plasma D-dimer levels. A cohort of 100 consecutive patients without overt heart disease referred to echocardiography for the detection of an occult arterial embolic source served as a control group. It consisted of 52 males and 48 females, median age 60 years. RESULTS: The study group included 87 women and 113 men, median age 64 years (range 21 to 91). The frequent malignancies were lymphoma (26%), carcinoma of the gastrointestinal tract (20%), and carcinoma of the lung (16%). Cardiac valvular vegetations were found in 38 patients (19%) compared with only in 2 patients in the control group (2%, P < 0.001). Vegetations were found on the mitral or on the aortic valve in 19 and 18 patients, respectively. Isolated tricuspid valve vegetation was found in 1 patient. Valvular lesions were mostly common in patients with carcinoma of the pancreas (3 of 6, 50%), carcinoma of the lung (9 of 32, 28%), and lymphoma (10 of 52, 19%). Thromboembolism was diagnosed in 22 (11%) patients (12 deep vein thrombosis, 4 emboli to extremities, 2 cerebrovascular accidents, and 4 "silent" segmental left ventricular wall motion abnormalities on echocardiography). Thromboembolism was noticed in 9 of 38 patients (24%) with vegetations compared with 13 of 162 patients without vegetations (8%; P = 0.013). Plasma D-dimer level was examined in a subgroup of 170 patients. D-dimer level was increased in 19 of 21 patients (90%) with thromboembolism compared with 76 of 149 patients without thromboembolism (51%; P = 0.001). CONCLUSIONS: This study demonstrated a high prevalence of cardiac valvular lesions in patients with solid tumors. Vegetations were associated with thromboembolism. Plasma D-dimer level was significantly increased in patients with thromboembolism.

Superior vena cava syndrome as a primary manifestation of Behçet's disease. A case report.

Superficial thrombophlebitis is a common finding in Behçet's disease. However, the potential life-threatening complication of superior vena cava (SVC) syndrome due to thrombotic occlusion is a rare manifestation and usually occurs several years after the onset of the diagnosis. The authors describe a twenty-nine-year-old Arab man who had an acute thrombosis of the SVC as the presenting manifestation of his Behçet's disease. The patient was successfully treated with thrombolytic and anticoagulant therapy, and during follow-up no relapse was observed. Behçet's disease should be suspected in young patients presenting with thrombosis of the SVC and without evidence of a hypercoagulable state.

[Sulfonylurea-induced factitious hypoglycemia].

3 patients with recurrent, symptomatic hypoglycemia associated with increased insulin and C-peptide blood levels are described. 2 men aged 37 and 21-years had mental and social problems and although they had access to sulfonylurea drugs, both denied intake. 1 was scheduled for pancreatectomy, but as a result of the vigilance of the surgeon, the operation was canceled. By demonstrating sulfonylurea in their urine, a definitive diagnosis of factitious hypoglycemia was established, and further invasive procedures were avoided. The third was a woman aged 40-years had malignant insulinoma with liver metastases, proven by cytology. The common and differentiating clinical and laboratory characteristics of hypoglycemia due to insulinoma and factitious hypoglycemia secondary to sulfonylurea intake are discussed, and the importance of urine analysis demonstrating the presence of sulfonylurea is emphasized.

[Primary malignant mediastinal germ cell tumor causing pericardial effusion].

A 19-year-old man presented with chest pain, dyspnea and dry cough. Chest X-ray and computerized tomography showed a large, anterior, mediastinal mass. 2-dimensional echocardiography demonstrated a large amount of pericardial fluid. Serum alpha-fetoprotein was increased. Fine-needle, aspiration cytology during anterior mediastinotomy revealed malignant cells. Anterior thoracotomy demonstrated a large, anterior, mediastinal mass extending into the pericardial sac. The tumor was incompletely resected and 700 ml of pericardial fluid were removed. Histological examination showed a malignant, mixed, germ cell tumor. Cytologic examination of pericardial fluid revealed malignant tumor cells. Postoperatively, combined chemotherapy was administered and 3 years later the patient is free of symptoms.

[Ischemic hepatitis].

In ischemic hepatitis, which is not rare, there is a marked but transient increase in serum aminotransferase activity to at least 20 times the upper limit of normal, without any other cause for hepatic necrosis. It is generally preceded by an acute cardiac complication, usually pulmonary edema or a tachyarrhythmia, causing decrease in cardiac output, or may follow acute respiratory failure. The typical histological lesion is centrilobular hepatic necrosis. We present 2 cases of ischemic hepatitis due to hypotension following rapid atrial fibrillation, sepsis and acute respiratory failure, highlighting the different etiologies, laboratories results, and the relative benign course, described in the literature. The patients were a woman aged 80 and a man aged 76. Awareness of the place of this disorder in the differential diagnosis of acute hepatitis may save needless, dangerous investigations.

Cardiac function and responsiveness to beta-adrenoceptor agonists in rats with obstructive jaundice.

The function and role of the heart and the contribution of cardiac beta-adrenoceptors in the pathogenesis of circulatory failure in obstructive jaundice were studied in the 3-day bile duct-ligated (BDL) rat using three different techniques to measure cardiac function and beta-adrenoceptor activity, number, and affinity. The techniques were the pithed rat preparation, the isolated working heart preparation, and a competitive radioligand binding assay for beta-adrenoceptors. The results of these experiments were compared with those obtained in 3-day bile duct-manipulated (sham operated; SO) rats. Impaired indexes of basal cardiac contractility were observed in the BDL pithed rats and isolated working hearts. In these two preparations, responsiveness to norepinephrine and the beta-adrenoceptor agonists, isoproterenol and dobutamine, was unaffected by bile duct ligation. The affinity and number of cardiac beta-adrenoceptors in membranes from the hearts of SO and BDL rats were not significantly different from each other. These experiments have established for the first time that the 3-day BDL rat has a cardiac myopathy associated with intact responsiveness to beta-adrenoceptor agonists, a normal unchanged affinity and number of cardiac beta-adrenoceptors.

Ro 5-4864 and PK 11195, but not diazepam, depress cardiac function in an isolated working rat heart model.

The present study was designed to investigate the effects of diazepam, a benzodiazepine (BZ) with high affinity to central BZ receptors and moderate affinity to mitochondrial BZ receptors, and of Ro 5-4864 and PK 11195, ligands specific for mitochondrial BZ receptors, on cardiac function in the isolated working rat heart model. Five concentrations of these drugs (10(-9)-10(-5) mol/l) were used, and the chronotropic (heart rate) and inotropic [maximum elastance of the left ventricle at end systole (Emax), maximal first derivative of left ventricular (LV) pressure (dP/dtmax), LV pressure at dP/dtmax (pressure at dP/dtmax), aortic flow, stroke work, and total pressure-volume area] cardiac parameters were measured. Diazepam, Ro 5-4864, and PK 11195 showed no significant chronotropic activity up to 10(-5) mol/l. Diazepam did not alter the inotropic properties of the heart. Ro 5-4864 at 10(-5) mol/l significantly decreased the indices of contractility, namely, Emax, dP/dtmax, and pressure at dP/dtmax. Aortic flow, stroke work, and total pressure-volume area were significantly depressed at the same concentration. The negative inotropism of PK 11195 appeared to be identical, by most indices, to that of Ro 5-4864, both qualitatively (same pattern) and quantitatively (similar maximal variations); however, for some indices a depressant effect was also found at 10(-7) mol/l. These results show that at high concentrations Ro 5-4864 and PK 11195, but not diazepam, have a depressant effect on mechanical function.
