Scientists Have Found The Effect Of Silica On The Lungs.
More vigour is needed to demote illness and death among the millions of Americans exposed to silica dust at work, according to a reborn report Dec, 2013. It has large been known that silica - a natural substance found in most rocks, sand and clay - causes the lung cancer silicosis, and evidence has mounted in recent decades that silica causes lung cancer, said come in co-author Kyle Steenland, of the School of Public Health at Emory University. "Current regulations have at bottom reduced silicosis death rates in the United States, but additional cases of silicosis continue to be diagnosed".
Recommended measures include stronger regulations, increased awareness and prevention, and greater prominence to early detection of silicosis and lung cancer using low-dose CT scanning, the researchers said in the prevailing issue of CA: A Cancer Journal for Clinicians. "While the lung cancer peril associated with silica exposure is not as large as some other lung carcinogens, equal smoking or asbestos exposure, there is strong and consistent evidence that silica hazard increases lung cancer risk," Steenland said in a journal news release.

Cancer Risk From CT Scans Lower Than Previously Thought
Cancer Risk From CT Scans Lower Than Previously Thought.
The chance of developing cancer as a development of radiation exposure from CT scans may be drop than previously thought, new research suggests. That finding, scheduled to be presented Wednesday at the annual congregation of the Radiological Society of North America in Chicago, is based on an eight-year criticism of Medicare records covering nearly 11 million patients. "What we found is that overall between two and four out of every 10000 patients who live a CT scan are at risk for developing secondary cancers as a result of that shedding exposure," said Aabed Meer, an MD candidate in the department of radiology at Stanford University in Palo Alto, Calif. "And that risk, I would say, is bring than we expected it to be".
As a result, patients who for a CT scan should not be fearful of the consequences, Meer stated. "If you have a iota and need a CT scan of the head, the benefits of that scan at that moment outweigh the very child possibility of developing a cancer as a result of the scan itself. CT scans do amazing things in terms of diagnosis. Yes, there is some emanation risk. But that small risk should always be put in context".
The authors set out to quantify that jeopardize by sifting through the medical records of elderly patients covered by Medicare between 1998 and 2005. The researchers separated the statistics into two periods: 1998 to 2001 and 2002 to 2005. In the earlier period, 42 percent of the patients had undergone CT scans. For the patch 2002 to 2005, that illustration rose to 49 percent, which was not surprising given the increasing use of scans in US medical care.
Within each group, the analyse team reviewed the number and quintessence of CT scans administered to see how many patients received low-dose radiation (50 to 100 millisieverts) and how many got high-dose diffusion (more than 100 millisieverts). They then estimated how many cancers were induced using yardstick cancer risk models.

Very Loud Music Can Cause Hearing Loss In Adolescence
Very Loud Music Can Cause Hearing Loss In Adolescence.
Over the persist two decades hearing diminution due to "recreational" noise exposure such as blaring thrash music has risen among adolescent girls, and now approaches levels previously seen only in the midst adolescent boys, a new study suggests. And teens as a whole are increasingly exposed to thunderous noises that could place their long-term auditory health in jeopardy, the researchers added. "In the '80s and beginning '90s young men experienced this kind of hearing damage in greater numbers, all things considered as a reflection - of what young men and young women have traditionally done for make use of and fun," noted study lead author Elisabeth Henderson, an MD-candidate in Harvard Medical School's School of Public Health in Boston.
And "This means that boys have loosely been faced with a greater station of risk in the form of occupational noise exposure, fire alarms, lawn mowers, that humanitarian of thing. But now we're seeing that young women are experiencing this same level of damage, too". Henderson and her colleagues news their findings in the Dec 27, 2010 online print run of Pediatrics.
To explore the risk for hearing damage among teens, the authors analyzed the results of audiometric testing conducted all 4,310 adolescents between the ages of 12 and 19, all of whom participated in the US National Health and Nutrition Examination Surveys. Comparing thundering noise publication across two periods of time (from 1988 to 1994 and from 2005 to 2006), the pair determined that the degree of teen hearing loss had generally remained relatively stable. But there was one exception: teen girls.
Between the two workroom periods, hearing loss due to loud clangour exposure had gone up among adolescent girls, from 11,6 percent to 16,7 percent - a very that had previously been observed solely among adolescent boys. When asked about their past day's activities, observe participants revealed that their overall exposure to loud noise and/or their use of headphones for music-listening had rocketed up, from just under 20 percent in the up to date 1980s and early 1990s to nearly 35 percent of adolescents in 2005-2006.

Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation
Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation.
With May designated as UV awareness month, experts are work on parents to remunerate deliberate heed to the safety of their children's eyes this summer. Although eye refuge is a concern for people of all ages, Prevent Blindness America, the nation's oldest eye healthfulness and safety organization, warns that children are particularly vulnerable to the harmful ultraviolet A and B (UVA and UVB) mutilate that can accompany sun exposure. For one, children commonly spend more time in the sun, the group noted.
In addition, the organization highlights the American Optometric Association's cautionary find that the lenses of young eyes are more transparent than that of adults, risking retinal endangerment to a greater degree of short wavelength light. "We need to remember to mind our eyes from UV every day of the year," Hugh R Parry, president and CEO of Prevent Blindness America, said in a account release. "UV rays reflecting off the water, sand, pavement and even snow are exceptionally dangerous. We can encourage our children to wear the proper lookout protection by leading by example".
UV exposure has been linked to the onset of cataracts, macular degeneration and a sizeable array of eye health issues, the experts noted. Prevent Blindness America advises that each and every one who goes out in the sun should wear sunglasses that block out 99 percent to 100 percent of both UVA and UVB dispersal - noting that sunglasses without such protection can actually cause the pupils to dilate, thereby doing more maltreat than good. A wide-brimmed hat or cap also offers some measure of eye protection, the sort suggested.
With specific respect to children, Prevent Blindness America further encourages parents to safeguard that sunglasses fit their child's face properly and shields the sun's rays from all directions. The gathering points out that wrap-around sunglasses might be optimal in the later regard, because they additionally cover the skin immediately surrounding a child's eyes. Sunglasses, they note, should always be composed of impact-resistant polycarbonates, rather than glass, and should be scratch-free.

Psychologists Give Some Guidance To Adolescents
Psychologists Give Some Guidance To Adolescents.
Teen girls struggling with post-traumatic anxiety free-for-all stemming from sexual abuse do well when treated with a type of therapy that asks them to time after time confront their traumatic memories, according to a small new study. The study's results suggest that "prolonged disclosing therapy," which is approved for adults, is more effective at helping adolescent girls crush post-traumatic stress disorder (PTSD) than traditional supportive counseling. "Prolonged exposure is a specimen of cognitive behavior therapy in which patients are asked to recount aloud several times their traumatic experience, including details of what happened during the taste and what they thought and felt during the experience," said study initiator Edna Foa, a professor of clinical psychology at the University of Pennsylvania.
And "For example, a friend that felt shame and guilt because she did not prevent her father from sexually abusing her comes to realize that she did not have the drag to prevent her father from abusing her, and it was her father's fault, not hers, that she was abused. During repeated recounting of the harmful events, the patient gets closure on those events and is able to put it aside as something monstrous that happened to her in the past. She can now continue to develop without being hampered by the traumatic experience".
Foa and her colleagues reported their findings in the Dec 25, 2013 consummation of the Journal of the American Medical Association. The researchers focused on a class of 61 girls, all between the ages of 13 and 18 and all suffering from PTSD connected to sexual abuse that had occurred at least three months before the study started. No boys were included in the research.
Roughly half of the girls were given regulatory supportive counseling in weekly sessions conducted over a 14-week period. During that time, counselors aimed to care for a trusting relation in which the teens were allowed to address their traumatic experience only if and when they felt ready to do so. The other firm group was enlisted in a prolonged exposure therapy program in which patients were encouraged to revisit the originator of their demons in a more direct manner, albeit in a controlled environment designed to be both contemplative and sensitive.
