Tetraparesis is more often a clinical feature of profound hypokalaemia 1, 2 than hyperkalaemia. Neurological features ofhyperkalaemia are rarely seen in clinical practice, as they are precluded by cardiotoxic complications such as arrhythmias. However, patients may develop flaccid paralysis of skeletal muscle with areflexia mimicking symptoms of acute inflammatory demyelinating polyneuropathy.3...

A previously healthy 40-year-old male was admitted to investigate the second episode of an acute flaccid paralysis that occurred within 3 months. Both began suddenly in the early morning as generalized weakness evolving to paralysis within 2 h, and sparing respiratory and facial muscles. The paralysis was painless, and there was no disturbance of consciousness. Vital signs, including heart rate...

Poliomyelitislike paralysis can be caused by neurovirulent strains of nonpolioenteroviruses. Enterovirus 71 (EV 71) has been documented as one of the potentially neurovirulent strains and a causative agent of some epidemics [1-7). The clinical manifestations associated with EV 71 infection include aseptic meningitis, hand-foot-mouth disease (HFMD), acute respiratory illness, and gastrointestina...

BACKGROUND At the present time, in Brazil and other countries in the Americas, the only cases of paralytic poliomyelitis due to poliovirus are caused by vaccine strains. The recognition of possible determinants of vaccine-associated paralytic poliomyelitis (VAPP) by public health surveillance and immunization programmes is relevant to inform the debate on criteria for case definition and vaccin...
