WHO Declares H1N1 Virus Spread A Pandemic
WHO has declared that the spread of the H1N1 (swine) flu virus has reached pandemic level, the AP/Google.com reports (AP/Google.com, 6/11). The Phase 6 pandemic alert indicates that two regions of the world are experiencing significant outbreaks, according to the Wall Street Journal. The declaration came after WHO held an emergency meeting Thursday about raising the threat level. The Wall Street Journal writes that the WHO wants to "eliminate misunderstandings about the virus to prevent overreactions in some countries" (Esterl, Wall Street Journal, 6/11).

New Image Survey Reveals 'Perception Is Reality' When It Comes To Teenagers With Acne
In today"s image-obsessed society where millions of photos are uploaded daily through digital networks such as Facebook and Flickr, how much of an impact can a common skin condition like acne have on the life of teens? Based on first impressions, teens with acne are perceived to have different personality and social traits than if they had clear skin, according to results of a new online perception survey sponsored by the American Acne & Rosacea Society (AARS), and co-authored by Dr. Eva Ritvo, psychiatrist and co-author of The Beauty Prescription.(1) The survey asked thousands of teens and adults to offer their impressions of a group of teens based solely on photos of their faces - with clear skin or digitally enhanced to simulate acne. The results, which are being released to mark the first-ever National Acne Awareness Month, also expose the significant lengths that teens with acne would go to if it meant they could get rid of their acne forever.(1a)

What Is Puberty? What Is Early Puberty? What Is Late Puberty?
Puberty is the period in children"s lives when they experience physical changes by which their bodies eventually become adult bodies that are capable of reproducing. Puberty is triggered by hormone signals from the brain to the ovaries and testes (gonads). The ovaries (in girls) and testes (in boys) respond to hormone signals from the brain by producing a range of hormones that stimulate the growth, function and change in various parts of the body, including the reproductive organs, breasts, skin, muscles, bones, hair and the brain.

Research: Improving Treatment Of Patients With Heart Attack

When faced with patients suffering a heart attack, doctors have two choices: inject them with medication to dissolve the blood clot (fibrinolytic therapy) or insert a small balloon to open the blocked artery (primary percutaneous coronary intervention (PCI)). Guidelines for treating heart attacks are generally based on clinical trials that do not take "real-life" conditions into account. The latest study by Dr. Thao Huynh of the Research Institute of the MUHC analyses these gaps and provides potential solutions to improve treatment of heart attack. Her article was published in the June 23rd issue of Circulation. In this study, Dr. Huynh compares the results of 23 randomized controlled trials conducted under controlled experimental conditions, with the results of 32 observational studies reporting on the treatment of patients with heart attacks in routine clinical conditions. Both types of studies show the superiority of PCI over fibrinolytic therapy in reducing mortality and the risk of further episodes of cardiac arrest and stroke over the short term. However, the advantage of PCI is even more apparent in randomized controlled trials where delays in providing primary PCI are shorter than in routine clinical conditions. "This study indeed demonstrates that we have to work to reduce these delays if we are to maximize the effectiveness of PCI," explained Dr. Huynh. "When it comes to treating heart attack, reducing delays in providing treatment is the number one priority. It is also essential that patients with symptoms of heart attack seek prompt medical attention. Delays by patients to seek medical attention may further increase delays to treatment of heart attack. " Analysis of randomized controlled trials shows that primary PCI also reduces long-term mortality and repeat heart attack. However, this long-term benefit of primary PCI is not observed in observational studies where patients receive treatment within routine clinical conditions. "The benefit of primary PCI can be lost over the long term if patients are not receiving optimal medical therapy after discharge from hospital. These medications are essential to prevent repeat heart attack." warned Dr. Huynh. Dr. Thao Huynh Dr. Thao Huynh is a cardiologist at the MUHC and a researcher in the Cardiovascular Diseases and Critical Care Axis at the Research Institute of the MUHC. She is also an Associate Professor in Division of Cardiology at the McGill Health University Center. Funding This study was funded by the Agence d"çİvaluation des technologies et modes d"intervention du Quçİbec (AETMIS), Canadian Institutes of Health Research (CIHR) Team Grant, and the Department of Medicine of McGill Health University Center.
