Cardiac abnormalities has been receiving increased attention in patients with systemic lupus erythematosus (SLE). Cardiovascular system involvement has been found to have a substantial effect on mortality and morbidity in patients with SLE [1]. Recent diagnostic methods using echocardiography examination have allowed the delineation of cardiac manifestations such as myocarditis and myocardial dysfunction, valvular disease, pericardial disease or pulmonary hypertension. A report of two cases is presented: 23-year-old man with acute myocarditis with left ventricular failure and pulmonary oedema as a initial presentation of active SLE, and 51-year-old woman with SLE, antiphospholipid antibodies, with history of cerebral embolic infarction, TIA and venous thrombosis and with mitral valvular dysfunction in course of nonbacterial thrombotic endocarditis. Pulmonary hypertension has been recognised in both patients probably as a result of vasculaopathy and intimal proliferation, vasculitis, thromboembolic disease or parenchymal lung disease in SLE. Recent advances in diagnosis and treatment have substantially improved the prognosis of patients with systemic lupus erythematosus and cardiovascular system involvement [2].

Noncardiogenic pulmonary edema, and, to a lesser extent, acute respiratory distress syndrome (ARDS), are common clinical manifestations of drug-induced lung diseases. Clinical features and radiographic appearances are generally indistinguishable from other causes of pulmonary edema and ARDS. Typical manifestations include dyspnea, chest discomfort, tachypnea, and hypoxemia. Chest radiographs commonly reveal interstitial and alveolar filling infiltrates. Unlike pulmonary edema that is due to congestive heart failure, cardiomegaly and pulmonary vascular redistribution are generally absent in cases that are drug-related. Rare cases of drug-induced myocarditis with heart failure and pulmonary edema have been described. Results from laboratory evaluation and respiratory function tests are nonspecific.

Acute heart failure is always an indication for referral to an intensive care unit. In the widest sense, the term acute heart failure includes the manifestation forms of pulmonary edema, cardiogenic shock or rapid-onset decompensated cardiac insufficiency unaccompanied by shock or pulmonary edema (low-output syndrome). Acute heart failure may occur in the absence of previously known heart disease. Existing prior specific diseases that may end in acute cardiac insufficiency include acute myocardial infarction, decompensated cardiomyopathy, myocarditis, cardiac tamponade, endocarditis or arrhythmogenic heart failure.

The seriousness of scorpion envenomation results essentially from left cardiac function with pulmonary oedema and/or a state of shock. Adrenergic myocarditis, toxic myocarditis and myocardial ischemia are the 3 mechanisms that explain the cardiac dysfunction. Myocardial ischemia is not only due to the release of catecolamines but also the effect of the cytokines and/or neuropeptide Y on the coronary vessels. The cardiac damage can be due or enhanced by the depressive effect of the cytokines on the myocardial cells. The frequently observed hyperglycaemia only enhances the state of the already damaged myocardium.

Highly pathogenic avian influenza (HPAI) was diagnosed in broiler breeders, submitted to the National Veterinary Research and Quarantine Service in South Korea. Grossly, the dead breeders had lesions consistent with HPAI, including pancreatic mottling, splenomegaly, pulmonary edema and congestion, and hemorrhages in the mucosa of the proventriculus, gizzard and small intestine, and on the serosal surface. Microscopically, there were necrotized hepatitis and pancreatitis, lymphocytic meningoencephalitis, myocarditis, and interstitial pneumonia. Influenza viral antigen was demonstrated in areas closely associated with histopathologic lesions. The AI virus was isolated from cecal tonsils, feces, trachea, and kidney of the chickens. The isolated virus was identified as the highly pathogenic H5N1, with a hemagglutinin proteolytic cleavage site deduced amino acid sequences of QREKRKKR/GLFGAGLFGAIAG. In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all the birds died within 24 hr after inoculation. This is the first report of an outbreak of HPAI in the chickens in South Korea.

From July through December 1997, 11 previously healthy children in Peninsular Malaysia succumbed to an illness clinically characterised by an acute severe refractory left-ventricular failure, following a brief prodromal illness, in the midst of an outbreak of hand, foot and mouth disease (HFMD), similar to the reported experience in Sarawak and Taiwan. Retrospective reviews of the clinical features and results of laboratory, pathological and virological investigations of cases were conducted. The median age of the 11 case-patients was 31 months (range, 13 to 49 months); 6 were males. A brief prodromal illness of 3 days (range, 2 to 5 days) was characterised by fever (axillary temperature > 38 degrees C) (100%), oral ulcers (72%), extremity rashes (45%) and significant vomiting (55%). Upon hospitalisation, 7 of 11 case-patients had features suggestive of cardiogenic shock, while 4 of 11 case-patients developed shock during hospitalisation as evidenced by marked sustained tachycardia (heart rate > or = 180 beats per minute), poor peripheral pulses and peripheral perfusion, mottled extremities, pulmonary oedema (haemorrhagic pulmonary secretions in 8 of 11 cases during tracheal intubation, often precipitated by conservative crystalloid boluses, and radiographic evidence of acute pulmonary oedema in 5 of 7 cases) and markedly impaired left ventricular function on echocardiographic examination (7 of 7 cases). Three of 4 case-patients had aseptic meningitis while one case-patient also had an acute flaccid paraparesis. Despite supportive therapy, death occurred within a median of 13.4 hours following hospitalization. Post-mortem findings (all 8 specimens examined) consistently demonstrated brain-stem encephalitis with foci of neuronal necrosis and micro-abscesses. None of the 11 specimens examined revealed histological evidence of myocarditis. Enterovirus 71 (EV71) was detected in 10 of 11 case-patients, many (7) from various sterile tissue sites (5 from central nervous tissues). No other viruses were isolated or identified. Clinical features and pathological studies closely paralleled the reported experience in Sarawak and Taiwan. The uniform necropsy findings of necrotizing brain-stem encephalitis coupled with essentially normal myocardial histology, in concert with the concurrent and consistent detection of EV71 points to a primary EV71 encephalitis; as yet unclear neurogenic mechanisms may account for the cardiovascular manifestations.

Scorpion sting is a common problem in villages of Eastern Nepal. The life-threatening complications of myocarditis and pulmonary edema is known in red scorpion in India but not reported in Nepal. This condition requires urgent attention and ICU care from few hours to days. Delay in recognition and the hypoxemia increase the morbidity and mortality. Illiteracy, ignorance, poverty, traditional faith healers trying treatment in remote areas, lack of transport in difficult terrains and the non availability of ventilation facility in nearby hospital, add to delay in appropriate treatment. Seven young adult patients admitted in a span of two years with history of scorpion sting presenting with pulmonary edema required ICU care. They were successfully managed with the positive pressure ventilation with PEEP, cardiac support with inotropes and fluid balance. Magnitude of problem, clinical presentation and management done is emphasized.

We report the echocardiographic findings in a 27-year-old woman with viral meningoencephalitis and a positive test for cardiac troponin. Initially, the basal parts of the left ventricle were severely hypokinetic, whereas contraction in the mid-ventricle and apex was normal. A second echocardiogram obtained 19 days after the development of pulmonary edema showed a generalized, severe myocardial thickening, the left ventricular ejection fraction being normal. Three months after the initial examination the "hypertrophy" had disappeared. The serial echocardiograms along with a positive cardiac troponin led to the diagnosis of myocarditis, which can very rarely present with the echocardiographic picture of severe left ventricular thickening.

Myocarditis associated with reovirus was diagnosed in 17-day-old, male turkey poults, based on virus isolation, reverse transcriptase-polymerase chain reaction (RT-PCR), demonstration of reovirus antigen in the cytoplasm of mononuclear inflammatory cells and myocytes in the heart by immunohistochemistry (IHC), and reovirus particles in the endoplasmic reticulum of myocytes by transmission electron microscopy (TEM). Clinical signs in the poults included anorexia, growth depression, and increased mortality. Gross lesions in the six poults examined were increased pericardial fluid, mild-to-moderate dilation of right ventricles, pale-yellow myocardium, and ascites. Other lesions in a few birds included mild pulmonary edema, congestion, and pale serosa of the small intestine that had watery contents in their lumens. Microscopically, in the heart, there was mild-to-severe necrosis of myocytes and infiltration of primarily lymphocytes mixed with a few heterophils, macrophages, and occasionally, plasma cells and multinucleated giant cells. There was mild-to-moderate lymphoid depletion in the bursa of Fabricius. Reovirus was isolated from the heart of the turkey poults in chicken-embryo liver cells and was confirmed by RT-PCR, IHC, and TEM. A retrospective search of the laboratory database for cases of myocarditis associated with reovirus in turkeys revealed that this condition has occurred sporadically in California turkey flocks since 1991. This is the first documentation of myocarditis in turkey poults associated with reovirus.

Ephedra is an amphetamine-like compound with a potent sympathomimetic effect. Ephedrine, its active component, is widely used for weight loss, to enhance athletic performance or as component of some drugs. Its cardiovascular effects include tachycardia, increased inotropy, arterial vasoconstriction and hypertension, and these are the effects for which it is used therapeutically. However, it can also cause adverse effects, such as neuropathy, myopathy, psychosis, addiction, stroke, insomnia, myocarditis, arrhythmias, myocardial infarction or sudden death. We present the case of a patient, with pre-existing psychiatric conditions, who developed congestive heart failure and pulmonary oedema in the context of severe biventricular dysfunction and myocardial necrosis secondary to longstanding ephedrine abuse. Secondary causes of dilated myocardiopathy such as alcohol abuse, autoimmunity, hemochromatosis, thyroid alterations, viral or bacterial myocarditis and coronary heart disease, were ruled out. Five years after total cessation of use of the drug containing ephedrine, the patient is symptom-free, with partial recovery of left ventricular ejection fraction.
