Relationship between gastro-oesophageal reflux and gastric activity in newborns assessed by combined intraluminal impedance, pH metry and epigastric impedance.

The pathogenesis of gastro-oesophageal reflux disease (GORD) is complex and multifactorial. A motility disorder resulting from immaturity of the gastro-oesophageal tract may be involved. We have combined multichannel intraluminal impedance (MII) and pH monitoring with epigastric impedance (EGI) to evaluate the activity of this tract in neonates with suspected GORD.

A prospective 10-year study on children who had severe infantile colic.

Aim: To evaluate the association between infantile colic and gastrointestinal, allergic and psychological disorders in childhood.

Methods: A prospective study was conducted on 103 infants aged 31-87 d. After 10 y, between 2001 and 2003, the children were recalled and a paediatrician evaluated the selected disorders by anamnesis, medical examination, laboratory tests and parent interviews.

Influence of thyroid in nervous system growth.

Nervous system growth and differentiation are closely correlated with the presence of iodine and thyroid hormones in initial development stages. In the human species, encephalon maturation during the first quarter of pregnancy is affected according to recent studies by the transplacenta passage of maternal thyroid hormones while it depends on initial iodiothyronin secretion by the foetal gland after the 12th week of pregnancy. Thyroid hormone deficiency during nervous system development causes altered noble nervous cells, such as the pyramidal cortical and Purkinje cells, during glial cell proliferation and differentiation alike.
