During an outbreak of hand-foot-mouth disease caused by enterovirus 71 (EV-71) in 1997, 4 children presented with sudden cardiopulmonary collapse and minimal neurologic features. All children received cardiopulmonary resuscitation but died within a few hours of admission. Postmortem studies showed infection by EV-71 with extensive damage to the medulla and pons. We postulate an etiologic link between EV-71 and brainstem encephalomyelitis as the cause of pulmonary edema and death.

We report a fatal case of enterovirus type 71 (EV 71) infection in an 8-year-old girl during a summer outbreak of hand, foot, and mouth disease in 1998 in Taiwan. The clinical course was rapidly progressive, with manifestations of hand, foot, and mouth disease, aseptic meningitis, encephalomyelitis, and pulmonary edema. The patient died 24 hours after admission. Postmortem study revealed extensive inflammation in the meninges and central nervous system and marked pulmonary edema with focal hemorrhage. Brain stem and spinal cord were most severely involved. The inflammatory infiltrates consisted largely of neutrophils involving primarily the gray matter with perivascular lymphocytic cuffing, and neuronophagia. The lungs and heart showed no evidence of inflammation. EV 71 was isolated from the fresh brain tissues and identified by immunofluorescence method with type-specific EV 71 monoclonal antibody. It was also confirmed by neutralization test and reverse-transcriptase polymerase chain reaction with sequence analysis. The present case was the first example in which EV 71 was demonstrated to be the causative agent of fatal encephalomyelitis during its epidemic in Taiwan.

Enterovirus (EV) can cause varied clinical manifestations. Involvement of the central nervous system (CNS) with the nonpolio EVs are common and important causes of morbidity in children. To investigate the manifestations of nonpolio enteroviral infections with CNS involvement during the EV outbreak, from February 1998 to January 1999, we collected 153 hospitalized patients in our pediatric ward caused by nonpolio EV infections which were diagnosed by history, clinical features, or detected from viral cultures. Fourteen patients (9.2%) had CNS presentations, 13 males and one female. The ages ranged from one month to 10.3 years. The spectrum of CNS presentations included aseptic meningitis (4 cases, 28.6%), encephalitis (5 case, 35.7%), encephalomyelitis (3 cases, 21.4%), and poliomyelitis-like syndrome (2 cases, 14.3%). Among these patients, 8 cases (57.1%) were isolated with EV71 from at least one site of rectal or throat swab sampling. Two fatal cases were presented as encephalitis and complicated with pulmonary edema. Generally, enteroviral infections are considered as a benign infectious disease in children. However, pediatricians should keep in mind that EV71 has caused several endemic outbreaks and continues to be an occasional cause of severe CNS disease. Early evaluation and appropriate treatment of CNS enteroviral infections may minimize the neurologic sequelae.

Enteroviruses are a common cause of childhood infections, from hand, foot and mouth disease, to lethal brainstem encephalitis. Enterovirus 71 was first isolated in 1969. Brainstem encephalomyelitis and pulmonary oedema are postulated to be causally related and have been found to be a common feature of fatal enterovirus 71 cases. A fatal case of enterovirus 71 infection in a 2-year-old, previously healthy boy is reported. He presented to the Department of Paediatrics with clinical features of sepsis within 3 days of onset of fever. A few minutes after injection of midazolam, fentanyl and vecuronium for intubation, cardiac arrest developed and was not amenable to various treatment modalities. Pulmonary haemorrhage and oedema were noted during intubation, and postmortem examination confirmed the presence of brainstem encephalomyelitis.

Brainstem lesions are rarely associated with neurogenic pulmonary oedema (NPO) in multiple sclerosis and other disorders. The exact mechanism for this is unknown. We describe a case of a 15-year-old boy who presented with transient cardiomyopathy and severe acute pulmonary oedema. Several days after his initial presentation he developed an ataxic syndrome with limb, truncal and gait ataxia and nystagmus on primary gaze. Investigations confirmed acute disseminated encephalomyelitis (ADEM). For the first time, we describe a case of transient cardiomyopathy and NPO as the initial manifestation of ADEM.
