Spontaneous conversion of supraventricular tachycardia followed by electromechanical dissociation.

We present this case to emphasize the potentially fatal outcome of supraventricular tachycardia in infancy, particularly if it has been undiagnosed for several days. Certainly, careful monitoring needs to take place during any attempt at cardioversion or any other noxious stimulation of the patient. Bicarbonate therapy should be provided if metabolic acidosis is present. Restoration of sinus rhythm may not guarantee an immediate return of normal cardiac function.

Causes of refusal to walk in childhood.

Refusal to walk is a common complaint in childhood. Its etiology was investigated by reviewing the charts of children who were admitted to the hospital with this problem in a one-year period. Bacterial infections produced 22 of the 55 episodes and were more likely to be associated with fever than were noninfectious disorders. Elevation in sedimentation rate and white blood cell counts were not helpful in differentiating infections from noninfectious disorders. Refusal to walk usually is associated with a serious underlying disease and this symptom should prompt a diligent search for its cause.

Constrictive pericarditis due to Streptococcus sanguis.

We have described the third case of pericarditis caused by anaerobic streptococci in children. Despite operative drainage and high-dose penicillin therapy, there was rapid progression to constrictive pericarditis. Complete pericardiectomy was life-saving.
