Infantile colic: is a pain syndrome.

The hypothesis states that infantile colic is a pain syndrome and the excessive crying leads to aerophagia and abdominal discomfort. The pain comes from sucking the bottle or the nipple. Feeding for the infant is a heavy workload for the masticatory muscles. The tiny digastricus muscle moves the hyoid bone, takes part in opening the mouth and retrusion of the mandible and assists in mowing the tongue upward, forward and backwards. In the adult population pain from this muscle is well documented. The hypothesis explains the crying as being due to muscular pain at first, later on pain from the origins and insertions of the muscle. Then with increased muscular strength and development the pain fades away.

Association of ApoE genotype with clinical features and outcome in idiopathic normal pressure hydrocephalus (iNPH): a preliminary report.

Fifteen patients suspected of having iNPH were clinically evaluated and their ApoE genotype determined prior to a possible ventriculoperitoneal shunt insertion. All patients fulfilling our criteria for intervention and who had a shunt implanted with good results were homozygous for the ApoE3/3 genotype.
