Asthma, Bronchitis Among Top Kids' Medical Conditions: Report
Latest MedicineNet News
Acute bronchitis, asthma, trauma-related disorders, middle-ear infections and mental disorders were the five most commonly treated medical conditions among U.S. children in 2008, a federal government report says.
More than 40 percent of the nation's children age 17 and younger were treated for at least one of those conditions that year, according to the latest News and Numbers from the Agency for Healthcare Research and Quality.
About 12 million children were treated for acute bronchitis, making it one of the most common ailments. However, bronchitis had the lowest treatment cost, an average of $226 per child.
Mental disorders were the fifth most commonly treated condition (5 million children) and had the highest treatment cost, an average of $2,483 per child.
Medicare paid the largest share of treatment costs for asthma (51 percent) and mental disorders (46 percent), while private insurance paid the largest share for the treatment of middle-ear infections (64 percent), trauma (62 percent) and bronchitis (55 percent).
New Bill Would Boost Monitoring of Medical Implants
Legislation introduced in the U.S. Senate Wednesday would require makers of artificial hips and other medical implants to monitor the performance of their products after they receive Food and Drug Administration approval.
Recently, there have been a number of problems with artificial hips and other medical implants and the bill is meant to address longstanding complaints by patients advocates and others about the FDA's approval system for certain types of implants, The New York Times reported.
Under what's known as the 510(k) process, the manufacturer need only show that a new product is "substantially similar" to a product already on the market. Thousands of all-metal hips approved under this process are now failing prematurely in patients.
The new bill would not require pre-approval testing of such medical implants but would give the FDA the power to force companies to gather data on the performance of the products. The bill would also boost federal scrutiny of product recalls, The Times reported.
U.S. Must Protect Research Participants: Panel
Greater transparency, easy-to-understand warnings for patients about the potential dangers of participating in studies, and high ethical standards should be required in research funded by the U.S. government, says a report released Thursday by the President' Bioethics Commission.
The commission also said federal officials should consider compensating victims who are harmed in future research financed by U.S. government dollars, Agence France-Presse reported.
The panel was convened by President Barack Obama last year after it was revealed that 1,300 people in Guatemala were exposed to venereal disease as part of U.S.-led research in the 1940s. The research resulted in 83 deaths.
Last year, the U.S. was involved in 55,000 human research projects worldwide, most of them for health and medical purposes, AFP reported.
Minnesota Boy Contracts Rare Swine Flu Strain
An extremely rare strain of swine flu has been reported in Minnesota infant who is only the second person ever to contract the H1N2 strain.
The boy was diagnosed in October and has since recovered, CBS News reported. There haven't been any other cases, according to health officials.
The flu shot does not protect against H1N2, which is common in pigs in the Upper Midwest, according to CBS local affiliate WCCO.
Neither the boy or his family had direct contact with swine and it appears his case is an unusual mutation of the H1N2 virus.
U.S. Had Record-Low Marriage Rate in 2010
A record-low 51 percent of adults aged 18 and older in the United States were married in 2010, compared with 72 percent in 1960, according to a Pew Research Center analysis of U.S. Census data.
The most dramatic decline in marriage has occurred among adults ages 18 to 29. Just 20 percent of them were married last year, compared with 59 percent in 1960.
The median age at first marriage is also at its highest -- 26.5 years for women and 28.7 years for men -- and over the past 50 years has risen by about six years for both women and men.
The decline in marriage has been accompanied by an increase in cohabitation, single-person households and single parenthood. If current trends continue, the percentage of U.S. adults who are currently married will fall below half within a few years, the researchers said.
They also found that the number of new marriages in the U.S. fell by 5 percent between 2009 and 2010.
