* When riding in cars, children older than four years are safer in belt-positioning booster seats. In a cross-sectional cogitation published in JAMA, researchers infered data on injuries to children four to seven years of age from insurance claims records and telephone contemplates in 15 states (probability sample of 3616 crashes involving 4243 children). Injuries occurr in 181 percent of all four- to seven-year-old children, including 195 percent of those in seat belts and 077 percent of those in belt-positioning booster seats. The risk of injury was 59 percent lower in the children who were in belt-positioning booster seats. In these children, there also were no reports of injuries to the abdomen, neck spine, back, or lower extremities. Belt-positioning booster seats function by way of raising a child up with equal reason that the seated height is more like that of an adult, allowing the car's seat belt to fit properly

* A medical mystery solved? A research published in Conservation Biology glance ats that an appetite for flying fox bats may be the reason for a high incidence of a neurologic disease in Guam's indigenous Chamorro nation Historically, up to one third of characters in every village developed a manifold neurologic syndrome with clinical features of amyotrophic lateral sclerosis, parkinsonism, and dementia.

* Are glare-reducing outcomes worn by athletes anything more than psychologic warfare? A consideration published in the Archives of Ophthalmology showed that vigilance black grease, a form of face paint smeared onward the cheekbones, does reduce glare and improve contrast sensitivity. Using a Pelli-Robson contrast chart, researchers criterioned 46 student volunteers from Yale University for contrast sensitivity changes as they faced into the sunny place for three hours. The learners first were tested without a glare-reducing produce and then randomized to application of notice black grease, antiglare stickers, or mineral pitch jelly (control) at the infraorbital rim. They showed a significant difference between organ of vision black grease and antiglare stickers or stone oil jelly.

* Carotid artery dissection is a possibility in patients who near with pulsatile tinnitus. In a case report published in The Lancet, a 40-year-old man currented to the emergency department with right-sided tinnitus. He first noticed the tinnitus after riding a bicycle for four hours in mountainous terrain. Magnetic resonance angiography showed right-sided carotid artery dissection with segmental los of issue signal and a hematoma in the ventral bottom wall. Aspirin was prescribed to convert into the risk of embolization, and the tinnitus resolv within united week. The authors of the case report noted that the cyclist's hyperextend neck plus the unpolished terrain probably contributed to the arterial dissection.

* Myth or fact: stres causes acne. It's a fact, according to the follows of a prospective cohort investigation published in the Archives of Dermatology. Twenty-two community students with acne were evaluated common month before any scholastic examination and again three days before to seven days after a proof period.
