Clinical signs of heart failure developed in two cardiac transplant recipients and were interpreted initially as graft rejection. Morphologic examination of explanted hearts revealed myocarditis with abscess formation and necrosis consistent with a bacterial process; Listeria monocytogenes was isolated from myocardial tissue in the first case and from blood in both. The first patient also developed signs of meningoencephalitis, but the second had no signs of infection outside the heart. Antimicrobial therapy and retransplantation were successful in eradicating listeriosis. The differential diagnosis of heart failure in cardiac transplant recipients includes infectious myocarditis due to L. monocytogenes.

We have defined the clinical presentation and course of X-linked agammaglobulinemia (X-LA) by means of a multi-center retrospective survey of 96 patients. Infections were the most common presenting feature of patients with X-LA. The most frequent infections involved the upper respiratory tract (75%), lower respiratory tract (65%), gastrointestinal tract (35%), skin (28%), and central nervous system (16%). Clinical clues to the diagnosis of X-LA were the chronic or recurrent nature of infections, a family history of immunodeficiency, and infections at more than one anatomic location. Infections remained a significant problem after the diagnosis of X-LA was made and gamma-globulin prophylaxis had been instituted. One or more chronic infectious diseases occurred in 71% of patients. The respiratory tract was the most common site of disease, and the gastrointestinal tract was relatively spared. Patients died at a mean age of 17 years. The two major causes of death were chronic pulmonary disease with resultant cardiac failure, and disseminated viral infections which characteristically caused a dermatomyositis-like syndrome, hepatitis, pneumonitis, and meningoencephalitis.

Death with trichinelliasis of a 30-year-old man who had used for food raw pork not subjected to trichinelloscopy is described. In the terminal period of the disease there was a clinical picture of ascending polyradiculoneuritis of the type of Landry syndrome which was the main clinical diagnosis. Morphological examinations revealed massive larval invasion of the voluntary muscles, trichinellous myositis, glossitis, myocarditis, meningoencephalitis, trichinellous pneumonia. The cause of death was severe toxicity, respiratory and cardiac insufficiency.

This report describes four cases involving French expatriates who developed serious health problems while living destitute in Senegal. A 37-year-old man presented with embolism-like symptoms in relation with lung involvement due to spreading of untreated staphylococcal skin infection. A 64-year-old man was admitted for high output cardiac failure secondary to severe anemia caused by malnutrition. A 50-year-old man presented recurrent fever with loss of consciousness after successful treatment of neuromalaria and finally attributed to delirium tremens. A 25-year-old man was hospitalized with presumed meningoencephalitis that had been ongoing for two weeks. All four patients had been in Senegal for several months and had cut all ties to mainland France. Being jobless and homeless, they had been unable to obtain proper nutrition or medications. With minimal entry requirements and low-cost air travel, Senegal has been come a common sight-seeing destination and has developed a small but apparently growing population of destitute travelers. Alienation from the home community and resulting seclusion enhance clinical consequences and delay intervention by foreign service officials.

We report electrocardiographic changes mimicking myocardial ischaemia in a 73-year-old man with fatal pneumococcal meningoencephalitis, present the autopsy-confirmed histological picture of extensive focal myocytolysis (contraction band necrosis) without myocardial infarction or myocarditis, and review the contemporary literature. Potentially reversible, probably non-ischaemic myocardial dysfunction may occur in association with acute noncardiac illnesses, such as brain injuries. Biochemical and morphological abnormalities in acutely failing hearts from head-injured organ donors point to specific pathophysiological mechanisms, which are different from heart failure from other causes. Sepsis-related factors may add to the myocardial dysfunction in patients with brain injury from meningoencephalitis.

Herod the Great, Idumean by birth, was king of the Jews from 40 to 4 BC. An able statesman, builder and warrior, he ruthlessly stamped out all perceived opposition to his rule. His last decade was characterised by vicious strife within his family and progressive ill health. We review the nature of his illnesses and suggest that he had meningoencephalitis in 59 BC, and that he died primarily of uraemia and hypertensive heart failure, but accept diabetes mellitus as a possible underlying aetiological factor. The possibility that Josephus' classical descriptions of Herod's disease could be biased by 'topos' biography (popular at the time), is discussed. The latter consideration is particularly relevant in determining the significance of the king's reputed worm infestation.

We compared characteristic lesions occurring in chickens and domestic ducks naturally infected with H5N1 HPAI virus in April and May 2008. Infected chickens generally exhibited pale-green, watery diarrhoea, depression, neurological signs and cyanosis of wattles and combs, and infected ducks generally exhibited neurological signs and watery diarrhoea. Gross petechial or ecchymotic haemorrhage affected the heart, proventriculus, liver, muscle, fat, and pancreas in chickens, and muscle in ducks. Necrotic foci were primarily present in the pancreas of both species and in the heart of domestic ducks. Histopathologically, chickens exhibited multifocal encephalomalacia, multifocal lymphohistiocytic myocarditis, multifocal necrotic pancreatitis and haemorrhage of several organs and tissues; ducks exhibited lymphohistiocytic meningoencephalitis with multifocal haemorrhages, multifocal necrotic pancreatitis, and severe necrotic myocarditis with mineralisation. The characteristic histopathologic findings of 2008 HPAI were multifocal encephalomalacia and necrotic pancreatitis accompanied by lymphohistiocytic myocarditis, and haemorrhage in various organs and tissues in chickens, whereas in ducks, they were severe necrotic myocarditis with mineralisation and necrotic pancreatitis, accompanied with lymphohistiocytic meningoencephalitis. The high mortality of domestic ducks may be intimately associated with heart failure resulting from increased H5N1 HPAI viral cardiotropism.

American trypanosomiasis is a parasitic disease caused by the flagellate protozoan Trypanosoma cruzi. Chagas disease is endemic in Latin America, where an estimated 10-14 million people are infected, and an emerging disease in Europe and the USA. Trypanosoma cruzi is transmitted by blood-sucking bugs of the family Reduviidae. Rhodnius prolixus, Panstrongylus megistus, Triatoma infestans, and T. dimidiata are the main vectors in the sylvatic cycle. Non vector-borne transmission includes blood transfusion, congenital and oral transmission, transplantation, and accidental infections. Most cases of acute infection occur in childhood and are usually asymptomatic, although severe myocarditis and meningoencephalitis may occur. Approximately 30% of T. cruzi-infected people will develop the chronic stage of the disease. Chronic chagasic cardiomyopathy is characterized by progressive heart failure, arrhythmias, intraventricular conduction defects, sudden death, and peripheral thromboembolism. Acute exacerbation can occur in individuals with involvement of cellular immunity such as advanced AIDS (acquired immunodeficiency syndrome), and transplant-associated immunosuppression. Neurological involvement may present with encephalitis, meningoencephalitis, or a space-occupying cerebral lesion called chagoma. Chagas disease is a major cause of ischemic stroke in Latin America. Several epidemiological studies have found an association between T. cruzi infection and cardioembolic ischemic stroke. Benznidazole and nifurtimox are the two available trypanocide drugs against T. cruzi.

Enterovirus infections are common in the neonatal period. Newborns are at a higher risk of severe disease including meningoencephalitis, sepsis syndrome, cardiovascular collapse, or hepatitis. The mechanism of heart failure in patients with enterovirus infection remains unknown. Early diagnosis may help clinicians predict complications in those infants initially presenting with severe disease. An 11-day-old male newborn was admitted to our neonatal intensive care unit because of tachycardia and crises of cyanosis. His elder brother had febrile illness. The newborn was cyanotic, in respiratory distress, with tachycardia, low blood pressure and prolonged capillary refilling time. Limb pulse oximeter was around 85%. During the first day of hospitalization, the newborn had one febrile episode. Laboratory data: elevated transaminases, markers of inflammation negative, all bacterial cultures negative. Enterovirus RNA was detected in blood sample. Other blood findings were without significant abnormalities. Electrocardiogram showed tachycardia, with narrow QRS complexes (atrial tachycardia) and heart rate up to 280/min. In order to convert the rhythm, the patient was administered adenosine and amiodarone. In the further course of hospitalization, the patient was in good general condition, eucardiac and eupneic. Newborns with tachycardia and a family history of febrile illness should be suspected to have enterovirus infection. Enterovirus infection is a highly contagious and potentially life-threatening infection if not detected early. The use of sensitive molecular-based amplification methods offers potential benefits for early diagnosis and timely treatment.

Chagas disease is a zoonosis caused by protozoan parasite Trypanosoma cruzi, which is most frequently associated with a vectorial transmission. However, in recent years we have observed a significant increase in the oral transmission of the disease, associated mainly with the consumption of drinks made from fruit or other vegetables contaminated with triatomine faeces or secretions from infected mammals. After a latency period of 3 to 22 days after ingestion, the oral infection is characterized by more severe manifestations than those associated with vectorial transmission: prolonged fever, acute myocarditis with heart failure and, in some cases, meningoencephalitis. Mortality can reach up to 33% of those infected. The aim of this paper is to review this matter and to promote prevention practices.
