1. INTERESTING NEWS STORIES

Hammond, LA -- A Wal-Mart Super Center customer said that he was bitten by a 6-inch rattlesnake while handling some
   plants. Animal control officers identified the snake as a Pygmy rattler and said that it was venomous. The victim said
   that he shook off the snake -- whose bite did not penetrate his skin -- and stomped it to death.

Lansing, MI -- An 11-year-old girl drown and her 13-year-old cousin nearly died trying to save her during a pool party. The
    older girl dived into the water and lost consciousness while trying to save her cousin. At the hospital, she asked about
    her cousin’s condition. Family members returned to the hotel pool where they found the 11-year-old at the bottom of
    the pool. No adults were supervising the pool party.

Jefferson, WI -- A 7-year-old girl died in a roller skating accident. An autopsy showed that the victim died of a skull
     fracture. The girl fell while skating and was crushed by a man who was skating backwards and did not see her on the
     floor.

Cheyenne, WY -- Firefighters say a woman saved her husband and two children from near-lethal levels of carbon
    monoxide when she came home from work and found then unconscious. The three family members were rushed to a
    hospital where they were treated and released. A faulty water heater in their mobile home was the suspected cause
    of the carbon monoxide leak.

Rochester, MN -- A 2-year-old boy who nearly died after wandering outside in subzero temperatures has been discharged
     from the hospital. Physicians call his recovery remarkable. When the boy was found by his father, his body
     temperature was in the low 60s.

Identifying Stroke
Reliable identification of stroke victims in the field by prehospital personnel could expedite treatment for stroke. The Los

     Angeles Prehospital Stroke Screen (LAPSS) is a one-page tool designed to allow prehospital personnel to rapidly
     identify acute stroke victims in the field. The LAPSS demonstrated that the positive predictive value was 97% when

Lay Persons Using AEDs
When utilized within the first few minutes of the collapse, defibrillation is the one factor scientifically proven to improve
     victim outcome from cardiac arrest. Beginning in 1997, researchers trained and equipped casino security officers
     from 32 locations around the United States in AED use. A standardized 6-hour training program was used. Data
     on all cases of ventricular fibrillation from March 1997 through October 1999 was collected for the study. A total of
     90 victims had a witnessed collapse and a documented rhythm of ventricular fibrillation. The survival rate was 74%
     in the group that received their first shock within three minutes of collapse. The survival rate dropped to 49% for
     the group that received shocks more than three minutes after collapse.
This study supports the need for widespread applications of AEDs by bystanders.

Toddler Drowning in Residential Swimming Pools

In Australia, more than half of the pediatric drowning fatalities occurred in unfenced pools and spas. Children gained
     access to fenced pools through faulty or inadequate gates or through gates that were propped open. Not one child
     gained unaided access to a pool fitted with a fully functional gate and fence that met the Australian standard. This
     finding highlights the need for pool owners to install approved fences and gates and to maintain existing fences
     and gates.

What is a Concussion?
A concussion is a violent jar or shock that injuries the central nervous system. A concussion may or may not cause loss
    of consciousness.

How Prevalent are Concussions?
The Centers for Disease Control and Prevention (CDC) estimates that 300,000 sports-related concussions occur per
    year (100,000 occur in football alone). An estimated 900 sports-related traumatic brain injury deaths occur per
    year. The risk of concussion in football is four to six times higher in players who have sustained a previous
    concussion.

What Happens to the Brain?
The brain is a jello-like substance that is vulnerable to outside trauma. The skull helps protect the brain against trauma,
    but does not absorb impact forces. During a concussion, the brain rotates and twists inside the skull, causing
    damage to brain tissue.

Signs of a Concussion
According to the American Academy of Neurology (AAN), symptoms of a concussion can appear early (minutes to
    hours) or late (days to weeks) . The early symptoms of concussion include:

* Impaired attention -- vacant stare, delayed responses, inability to focus * Slurred or incoherent speech
* Disorientation                                                * Emotional reactions that are out of proportion
* Memory deficits                                               * Any loss of consciousness
The late signs of concussion include:

* Persistent headache                 * Dizziness/vertigo                    * Poor attention and concentration
* Memory dysfunction                  * Nausea or vomiting                   * Fatigue easily
* Irritability                        * Intolerance of bright lights                      * Intolerance of loud noises
      11/11/2011
* Anxiety and/or depression                        * Sleep disturbances
                          First Aid Readings
Post-Concussion Syndrome
Lingering symptoms and continuing cognitive problems following a concussion may occur for weeks or months after the
     injury. Chris Miller said that after two concussions involving helmet-to-helmet hits, he felt, "…kind of out of sorts
     [for] two months afterward. I felt like I was punch drunk. I couldn't formulate thoughts or conversation."
Second-Impact Syndrome
The second-impact syndrome occurs when the head suffers another trauma while still healing from a previous
     concussion. The second-impact is more likely to cause brain swelling and other widespread damage. It can be
     fatal – there is a 50 percent death rate in the most severe cases of second-impact syndrome.
How is a Concussion Assessed?
The American Academy of Neurology classifies concussions into three grades:
* Grade 1: transient confusion, no loss of consciousness, and mental status abnormalities resolve in less than 15
     minutes.
* Grade 2: transient confusion, no loss of consciousness, and mental status abnormalities last more than 15 minutes.
* Grade 3: any loss of consciousness, either brief (seconds) or prolonged (minutes).

The AAN has issued recommendations on when a player can return to the field after a concussion. The
     recommendations are based on the grade of the concussion. If the player suffers another concussion of the same
     severity, then it is considered a “multiple” for the purposes of these recommendations. The player must show no
     symptoms of a concussion for the entire time period -- both while resting and while exercising.
* Grade 1 -- 15 minutes * Multiple grade 1 -- 1 week
* Grade 2 -- 1 week         * Multiple grade 2 -- 2 weeks
* Grade 3 (brief loss of consciousness) -- 1 week * Grade 3 (with prolonged loss of consciousness) --2 weeks
* Multiple grade 3 -- 1 month or longer, based on a doctor’s ruling
Conclusion
The benefits of helmet use in sports is obvious. Rule changes should be implemented to keep the head safer by
     making penalties tougher for those players who use head-butting as a tactic on the field. All players and coaches
     need to understand that fatalities can occur due to second-impact syndrome. Players, coaches, and parents need
     to11/11/2011
        work together to make all sports safer.
