French researchers reported that most children thought to be allergic to beta-lactam antibiotics such as amoxicillin actually were reacting to a viral infection rather than the antibiotic. Many infants with head injury have significant brain injury despite a lack of symptoms, according to a doctor at Childrens Hospital, Boston Massachusetts. Further CT scan studies are warranted for many infants with apparently benign injuries. He found children with no clinical signs or symptoms of brain injury and also no abnormalities of the scalp such as bruising do not need CT scan patients who have abnormalities of the scalp such as bruising or who are younger than 1 year, particularly those younger than 3 months of age are at higher risk of brain injury, even if there are no signs or symptoms of injury. The researchers advise physicians to consider CT imaging studies in these patients.
Young kids seem to have a lot of trouble learning to blow their noses.
Maybe they know something we don't. By using dye that would show up on CT scan of the sinuses, a researcher found that the pressure generated in the nose during the act of blowing was about 10 times greater than during sneezing or coughing, and that dye in the nose was forced into the sinus cavities by blowing the nose, but not by sneezing or coughing. This phenomenon may contribute to the development of sinus infections by forcing bacterial germs into the sinus cavities during nose blowing.
