... Following the Industrial Revolution technology has led to the identification and employment of a vast variety of chemicals. This has affected both agriculture and nutrition. The body's capacity to cope with chemicals is limited. Many, obviously, are toxic. What is safe is what is serviceable. Children, long before immune defences have been properly organised, are particularly vulnerable. Body chan ...
... Gastroesophageal reflux disease (GERD) is a motility disorder that occurs more frequently in children with neurological disease and in children with congenital esophageal anomalies or diaphragmatic hernia. Feeding difficulties and asthma may be caused by GER. Pharmacological and surgical treatment are successful in most cases. The authors describe 6 children with severe GER and asthma, who were tr ...
... Conditions leading to chronic pulmonary insufficiency can affect infants and children. These can lead to growth failure and delayed development. Among the most common and severe of these are bronchopulmonary dysplasia (BPD) and cystic fibrosis. In addition to the respiratory consequences of these diseases, there is ample evidence that they lead to decreased growth as a result of decreased energy i ...
