RESUMEN
A clearly defined progression of fasting small intestinal motor development is seen in the human infant from disorganised low amplitude motor activity before 31 weeks gestation through an intermediate phase of increasing motor organisation and amplitude to the development of a normal cyclical pattern of motor activity with clearly defined phase I, II, and III activity between 37 weeks gestation and term. With increasing maturity smooth muscle contractility [gastric antral pressure (5-30 mmHg), average duodenal pressure (2-12 mmHg)], propagation and slow wave frequency (10.5-12.5 cpm) all increased in a significant fashion (p less than 0.01). The stage of development of fasting motor activity in the small intestine of the preterm infant can now be readily predicted from the gestational age of the infant.

The development of motor activity within the small intestine of preterm human infants is very poorly understood. Using a miniaturized multilumen continuous perfusion manometric technique the motor activity of the small intestine was followed longitudinally in a group of preterm infants. The system performed well at very low perfusion rates and clearly showed increases in both the magnitude and organization of motor activity with increasing gestational age.

A 48-year-old patient presented with pneumonia and pleural effusion due to Mycoplasma pneumoniae, and subsequently developed pharyngitis and electrocardiographic evidence of myocarditis. The sparse literature on mycoplasma myocarditis is reviewed. The clinical features, electrocardiographic changes and prognosis are discussed.
