MS SUFFERERS WILL NOT SHARE DISEASE SEVERITY
Family members with multiple sclerosis (MS) are likely to share onset age, but not disease severity. US researchers examined data on 2,310 individuals from over 1,000 families in which at least two members had MS.  The age of onset, but not the severity of the disease, was similar amongst family members (Neurology Online 2007).

ANTIBIOTIC DOSES COULD BE REDUCED
Antibiotic doses could be reduced up to 50-fold using a new approach. US researchers believe bacteriophages' ability to channel through bacterial cell membranes could boost the effectiveness of antibiotics in food poisoning (Microb Drug Resist 2006; 12: 164).

VAGINAL BIRTH INCREASE HAEMORRHAGE RISK 
Vaginal birth can increase the risk of haemorrhage in newborns. In a US  study, 88 infants aged between one and five weeks underwent MRI of the brain. Of the 65 babies delivered vaginally, 26 per cent had intracranial haemorrhages or small bleeds in and around the brain. None of the 23 caesarean section babies   had signs of haemorrhaging (Radiology Online 2007).

DOLLS FAIL TO TACKLE TEENAGE PREGNANCY
Dolls that mimic the reality of parenthood fail to tackle teenage pregnancy, according to UK research. The dolls, which give a computer read-out on how well they are cared for were given to teenagers in Yorkshire. Researchers found no evidence that the dolls changed sexual behaviour. In some cases they appeared to encourage teenagers to become pregnant because they reportedly enjoyed the attention of motherhood (J Fam Plann Reprod Health Care 2007; 33; 35).
