Childhood vaccinations have become a very controversial topic over the past decade. In 1983, 10 vaccines were recommended for a child from birth to age six by the Centers for Disease Control (CDC). Today, the CDC recommends up to 36 vaccinations in the first six years of life. More families are stepping up and shunning inoculations. They are opting out for religious, medical or philosophical reasons. Every state has exemption vaccinations laws. Some states allow only medical and religious exemption, while others allow philosophical exemption. Less than one percent of school-age children in each state have exemption from vaccines, but the numbers are going up. The rates of opt out requests have nearly doubled in many school districts across the country. This means more and more kids are in school and are not vaccinated. This has the medical community concerned for general public health.
WASHINGTON - The toll from salmonella-tainted tomatoes jumped to 228 illnesses Thursday as the government learned of five dozen previously unknown cases and said it is possible the food poisoning contributed to a cancer patient's death.
Six more states - Florida, Georgia, Missouri, New York, Tennessee and Vermont - reported illnesses related to the outbreak, bringing the number of affected states to 23.
The Food and Drug Administration has not pinpointed the source of the outbreak. With the latest known illness striking on June 1, officials also are not sure if all the tainted tomatoes are off the market.

| Tomatoes with vines still attached are on sale at the Hunger Mountain Cooperative in Montpelier, Vt., Tuesday, June 10, 2008. U.S. officials hunted for the source of a salmonella outbreak in 17 states linked to three types of raw tomatoes, while the list of supermarkets and restaurants yanking those varieties from shelves and dishes grew. Cherry tomatoes, grape tomatoes, tomatoes sold with the vine still attached and homegrown tomatoes are likely not the source of the outbreak, federal officials said. |

Short sleep time is associated with overweight in children and adolescents, a core aspect of which may be attributed to reduced REM sleep, according to a research abstract that will be presented on Thursday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Xianchen Liu, MD, PhD, of the University of Pittsburgh, focused on 335 participants between seven and 17 years of age, who underwent three consecutive nights of standard polysomnography, or an overnight sleep test, and weight and height assessment as part of study on the development of childhood internalizing disorders (depression and anxiety).

A history of chronic insomnia in parents is not only associated with elevated risk for insomnia but also with elevated risks for use of hypnotics, psychopathology and suicidal behavior in adolescent offspring, according to a research abstract that will be presented on Thursday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
The study, authored by Xianchen Liu, MD, PhD, of the University of Pittsburgh, focused on 798 teenagers (450 boys and 348 girls), with an average age of 14.4 years, who completed a sleep and health questionnaire.
According to the results, compared with adolescents of parents without insomnia, participants of insomnia parents were more than twice more likely to report insomnia, daytime fatigue, and use of hypnotics. Adolescents of insomnia parents were also more likely to have depression, anxiety, and suicidal ideation and suicide attempts during the past year.

Teens who repeatedly cut themselves are more likely to engage in risky sexual behavior, increasing their chances of possibly contracting HIV, according to a study in the June issue of the Journal of Developmental and Behavioral Pediatrics.
Researchers from the Bradley Hasbro Children's Research Center in Providence, R.I. report that frequent self-cutters - teens who have cut themselves more than three times - used condoms less consistently, were more likely to share cutting instruments, and had less self-restraint. The study is the first to examine whether these teens engage in the same level of risk behaviors as those who've only experimented with cutting once or twice.
"This study sheds some much-needed light on the relationship between frequency of self-cutting and sexual risk, which could prove critical, given the rising rates of self-injury among adolescents," says lead author Larry K. Brown, M.D., of the Bradley Hasbro Children's Research Center (BHCRC). "Basically, we found that greater frequency seems to imply greater HIV risk, as these teens were more likely to share cutting instruments and participate in other risky activities that can expose them to HIV and other diseases."

After a stroke, waves of electrical discharge in the human brain cause more nerve cells to die / Researchers from Heidelberg an Cologne publish a study in the "Annals of Neurology".
After a stroke, even unaffected areas of the brain are at risk - depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die. This has previously been observed only in animal studies.
A clinical study at the university hospitals of Heidelberg and Cologne along with the Max Planck Institute of Neurological Research in Cologne has shown for the first time that this phenomenon occurs after a stroke in humans and is a warning sign that more nerve cells will die. The study, published in June 2008 in the renowned journal "Annals of Neurology," may allow to translate more than 60 years of experimental research for the diagnosis and therapy of stroke patients.

New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism.
Using functional magnetic resonance imaging, a team of researchers affiliated with the University of Washington's Autism Center also found that the most severely socially impaired subjects in the study exhibited the most abnormal pattern of connectivity among a network of brain regions involved in face processing.
"This study shows that these brain regions are failing to work together efficiently," said Natalia Kleinhans, a research assistant professor of radiology and lead author of the paper published in the journal Brain. "Our work seems to indicate that the brain pathways of people with autism are not completely disconnected, but they are not as strong as in people without autism."
The study is the first to look at brain connectivity and social impairment, and focused on how the brain processes information about faces. Deficits in face processing are one of the earliest characteristics to emerge in people with autism.

Scientists have found that bacteria that existed in the soil in 1960s and 70s have developed resistance to an antibiotic they 'have never seen before'.
The team looked at three strains of bacteria that showed extreme resistance to six common antibiotics, including ciprofloxacin, which was first sold in 1989.
"You can pretty safely say that there is no way these bacteria have seen them before," New Scientist quoted Cristiane San Miguel, a microbiologist at Rutgers University in New Brunswick, New Jersey, US, as saying.

Nairobi - Four people have died in an outbreak of visceral leishmaniasis, a parasitic disease also known as kalazar or black fever, in Isiolo and Wajir in northeastern Kenya, according to a senior health official.
Shahnaaz Sharif, the senior deputy director of medical services in Kenya's health ministry, said 66 people had been infected in the outbreak that was first reported in Wajir in April 2008.
