Levels of carcinoembryonic antigen(CEA)in the serum and pleural effusion in malignancies (65) and benign (25) of lung were determined. There are 20 cases of adenocarcinoma, 16 undifferentiated carcinoma, 7 squamous cell carcinoma, 4 alveolar carcinoma, 12 unclassified carcinoma, 1 polymorphous adenoma, 1 mesothelioma, 1 thymoma, 1 metastatic cancer from kidney and 2 metastatic breast cancer. In the benign lesions, there are 20 tuberculosis, 2 heart failure, 1 pneumonia, 1 empyema and 1 cirrhosis. The mean of the CEA level in the serum of lung cancer group was 12.63 ng/ml as compared with that of the tuberculosis group, 3.01 ng/ml (P less than 0.01). The level of CEA in pleural fluid in the lung cancer group was 57.30 ng/ml as compared with that of tuberculosis group, 5.55 ng/ml (P less than 0.01). The content of CEA in the serum and pleural fluid in lung cancer group was remarkably different (P less than 0.01). CEA level in the serum of adenocarcinoma is the highest (mean 15.51 ng/ml). If we set 5 ng/ml as the margin of normal CEA level in serum, the positive rate for cancer would be 54.2%. It is suggested that the margin of CEA normal value be set at 10 ng/ml for the pleural fluid. Higher readings may imply cancer.

Giant cell myocarditis is a rare disease of unknown etiology, which develops as a myocardial isolated affection or associated to different diseases. Its characteristics are such as necrosis, inflammation and giant cell presence in the myocardium. We present the case of a woman who suffered of giant cell myocarditis, thymoma, myasthenia gravis, chronic lymphocytic thyroiditis, giant cell myositis, granulomatous infiltration in the lymph nodes of the hilus of the lung and hypogammaglobulinemia; multiple association that we have not found in any published medical paper and that suggest the autoimmune origin of this illness. The cardiovascular symptoms and the associated diseases are revised, and we discussed the diagnostic and therapeutic topics, pointing out the necessity to take it into account for any patient with thymoma or myasthenia gravis developing to heart failure or arrhythmias.

A 68-year-old man presented to another hospital with progressive shortness of breath, dry cough, and systemic edema. A chest X-ray, echocardiogram, and chest CT showed a mediastinal mass and massive pericardial effusion. His symptoms improved after the treatment for heart failure. The pericardial effusion was bloody. In that, malignant cell wasn't proved. Thoracotomy was performed to diagnose the mediastinal tumor and to extirpate it. Pathological diagnosis after operation was thymoma with direct invasion to pericardium and tunica externa of aorta. Thymomas are routinely asymptomatic for prolonged periods of time. Symptomatic pericardial tamponade as initial manifestation due to a thymoma with a massive pericardial effusion is uncommon.

The management and clinical course of patients with myasthenia gravis admitted to a neurological intensive therapy unit (ITU) over a 66 month period were reviewed. Twenty-seven patients were admitted in myasthenic crisis, eight of whom had multiple admissions. One patient had a cholinergic crisis and a further patient an acute myocardial infarction. A specific aetiological factor precipitating myasthenic crisis was identified in 19 instances: infection (8), reduction in medication (5), menstruation (4), and steroid administration (2). Thirteen patients with crisis had had a previous thymectomy, six with thymoma. Twenty-three out of 35 (66%) patients admitted in crisis required intubation; nine subsequently needed a tracheostomy. Twenty-nine patients received plasma exchange and seven intravenous immunoglobulin. Four patients in myasthenic crisis died in ITU [adult respiratory distress syndrome (1), disseminated intravascular coagulation and cytomegalovirus (CMV) pneumonitis (1), cardiac failure (1) and multiple organ failure (1)]. Appropriate management of myasthenia gravis requires the easy availability of specialised neuro-intensive care facilities. Copyright Rapid Science Ltd

A cat was presented with acute-onset exfoliative erythroderma and gross and histopathological lesions of erythema multiforme. Marked cardiovascular abnormalities including heart failure occurred concurrently and a dermatogenic enteropathy was also seen. Medical treatment resolved the dermatopathy and enteropathy but the heart failure progressed. A drug reaction was initially suspected to be the underlying cause with no neoplasia being detected, but repeat radiographs subsequently revealed a thymoma which had not been visible on the initial radiographs. The dermatopathy may have been a paraneoplastic disease associated with thymoma and, possibly, exacerbated by a drug reaction to imidacloprid. The cardiovascular and gastroenterological diseases were thought to be systemic effects associated with the exfoliative erythroderma. The thymoma was surgically removed but the cat subsequently died from heart failure.

<Case 1> A 72-years-old man underwent radiation therapy (62 Gy) for esophageal carcinoma. Twelve months later, symptoms of heart failure such as syncope, cough and hepatomegaly manifested. On catheter study, a dip and plateau pattern of right ventricular pressure curve was evident. Pericardiectomy without extracorporeal circulation was performed. Operative findings and pathological results were compatible with radiation-induced constrictive pericarditis. He recovered from the heart failure, and has been doing well 3 months after the surgery. <Case 2> A 54-years-old man underwent thymectomy for malignant thymoma. He underwent a radiation therapy (52 Gy) postoperatively. After 12 months from the irradiation, syncope and dyspnea manifested. On catheter study, a dip and plateau pattern of right ventricular pressure curve was observed. Pericardiectomy with extracorporeal circulation was performed. He recovered from the heart failure after pericardiectomy, however he died of radiation-induced pneumonitis 6 months later.

We report a 62-year-old man with giant cell myocarditis and myositis associated with thymoma and myasthenia gravis (MG). He was diagnosed as having MG and invasive thymoma at the age of 45. After he had a myasthenic crisis at the age of 61, tacrolimus was indicated in order to improve his neurological symptoms, in addition to glucocorticoid. Three months later, he was readmitted to our hospital complaining of general fatigue and dyspnea. Serum level of creatine phosphokinase (9,835IU/L) and myocardium-derived troponin T (3.24 ng/mL) were elevated, and the ECG showed atrioventricular dissociation and accelerated idioventricular rhythm. In spite of glucocorticoid pulse therapies and high-dose immunoglobulin therapies, he died of cardiac failure within a few days. Autopsy was done, and histological examination of the myocardium and the skeletal muscle showed massive necrosis with infiltration of inflammatory cells including giant cells. These findings constituted giant cell myocarditis and myositis. Although it has been suggested that myocardial disorders can often occur in patients with thymoma and/or MG, the mechanism involved is still unknown. This report may provide new knowledge about the pathophysiology of giant cell myocarditis and myositis associated with thymoma and MG.

Giant cell myocarditis (GCM) is a serious condition that warrants immediate diagnosis and treatment. It often presents as rapidly progressive heart failure and/or malignant ventricular arrhythmias. Here, we describe a 34-year-old patient with myasthenia gravis who presented with GCM 2 weeks after resection of a thymoma. A cardiac biopsy confirming the diagnosis was done within 3 days after admission. After institution of an aggressive immunosuppressive drug regimen, implantation of an implantable cardioverter defibrillator, and intensive cardiac rehabilitation, the patient recovered dramatically. In control biopsies after 4 weeks and 6 months, no more giant cells were found. We conclude that, in the case of nonischemic acute heart failure in young patients, a biopsy should be performed as soon as possible to prevent an unfavourable outcome of this often fatal disease.

In the adult heart, a variety of stresses induce re-expression of a fetal gene program in association with myocyte hypertrophy and heart failure. Here we show that histone deacetylase-2 (Hdac2) regulates expression of many fetal cardiac isoforms. Hdac2 deficiency or chemical histone deacetylase (HDAC) inhibition prevented the re-expression of fetal genes and attenuated cardiac hypertrophy in hearts exposed to hypertrophic stimuli. Resistance to hypertrophy was associated with increased expression of the gene encoding inositol polyphosphate-5-phosphatase f (Inpp5f) resulting in constitutive activation of glycogen synthase kinase 3beta (Gsk3beta) via inactivation of thymoma viral proto-oncogene (Akt) and 3-phosphoinositide-dependent protein kinase-1 (Pdk1). In contrast, Hdac2 transgenic mice had augmented hypertrophy associated with inactivated Gsk3beta. Chemical inhibition of activated Gsk3beta allowed Hdac2-deficient adults to become sensitive to hypertrophic stimulation. These results suggest that Hdac2 is an important molecular target of HDAC inhibitors in the heart and that Hdac2 and Gsk3beta are components of a regulatory pathway providing an attractive therapeutic target for the treatment of cardiac hypertrophy and heart failure.

We report a case of invasive thymoma presenting with superior vena caval obstruction and intracardiac extension. A 74-year-old man was admitted in July 2002 with swelling of the face and right upper extremity. Computed tomography of the chest revealed a small anterior mediastinal mass, which infiltrated the lumen of the superior vena cava extending into the right atrium. Invasive thymoma was strongly suspected, but he refused any medical treatment. His health declined steadily, with repeated right-sided heart failure. He died due to cardiac tamponade 50 months after his first visit. On autopsy, the tumor was diagnosed as a thymoma classified as type B3 according to the WHO histological classification. Formation of a tumor thrombus in the superior vena cava and the right atrium is a rare mode of extension of thymoma. In this respect, our case may be valuable for improving the understanding of the natural course of invasive thymoma.
