1.2 million die on roads each year
Road accidents are the leading cause of death for youths from ages five to 29, and nearly
half of the 1.2 million traffic fatalities each year are pedestrians, cyclists and
motorcyclists, the World Health Organization said.
A mother's sensitivity may help
language growth in children with autism spectrum disorder
A new study by researchers from the University of Miami shows that maternal sensitivity
may influence language development among children who go on to develop autism. Although
parenting styles are not considered as a cause for autism, this report examines how early
parenting can promote resiliency in this population. The study entitled, "A Pilot
Study of Maternal Sensitivity in the Context of Emergent Autism," is published online
this month and will appear in an upcoming issue of the Journal of Autism and Developmental
Disorders. "Language problems are among the most important areas to address for
children with autism, because they represent a significant impairment in daily living and
communication," says Daniel Messinger, associate professor in the department of
psychology at the University of Miami (UM) College of Arts and Sciences and principal
investigator of a larger study of infants at-risk for autism, which includes this study.
Maternal sensitivity is defined in the study as a combination of warmth, responsiveness to
the child's needs, respect for his or her emerging independence, positive regard for the
child, and maternal structuring, which refers to the way in which a mother engages and
teaches her child in a sensitive manner. For example, if a child is playing with colored
rings, the mother might say, "This is the green ring," thus teaching the child
about his environment, says Messinger. In this study, maternal sensitivity (and primarily,
sensitive structuring) was more predictive of language growth among toddlers developing
autism than among children who did not go on to an autism diagnosis. One possible
explanation is that children with autism may be more dependent on their environment to
learn certain skills that seem to come more naturally to other children.
A week's exercise could be squeezed

hour, according to a new study.
Accelerated radiation therapy
reduces toxicity in patients with advanced head and neck cancers
Using an accelerated, shorter course of radiation therapy for patients with advanced head
and neck cancer allows doctors to reduce the amount of chemotherapy, thus reducing
toxicity, according to a study presented at the Multidisciplinary Head and Neck Cancer
Symposium, sponsored by AHNS, ASCO, ASTRO and SNM. Between July 2002 and May 2005, this
multi-institutional randomized phase III trial analyzed 721 patients with stage III-IV
carcinoma of the oral cavity, oropharynx, hypopharynx or larynx, with 360 receiving
accelerated radiation and 361 receiving standard radiation with two and three cycles of
cisplatin, respectively. After a median follow up of 4.8 years, the overall survival of
accelerated radiation patients versus standard radiation patients was 59 percent and 56
percent respectively. Disease-free survival rates were 45 percent and 44 percent
respectively and local-regional failure and metastasis rates were also very similar at 31
and 28 percent and 18 and 22 percent, respectively.
