Several theories exist to explain the link between periodontal disease and heart disease. One theory is that oral bacteria can affect the heart when they enter the blood stream, attaching to fatty plaques in the coronary arteries (heart blood vessels) and contributing to clot formation. Coronary artery disease is characterized by a thickening of the walls of the coronary arteries due to the buildup of fatty proteins. Blood clots can obstruct normal blood flow, restricting the amount of nutrients and oxygen required for the heart to function properly. This may lead to heart attacks.

Latest drowning statistics reveal a few interesting emerging trends
One would think that, over the summer holiday season, South Africa’s coastal areas experience the greatest increase in drowning incidences. The country’s beaches are jam-packed with holidaygoers, young and old, who don’t necessarily put safety first while being in their relaxed environment. But the latest statistics from the emergency medical services provider, Netcare 911, indicate an interesting trend.
Since the beginning of December, Netcare 911 has received more calls relating to drowning and water related emergency incidents from the country’s inland provinces than it has for the coastal areas. Between
1 December and 14 December, 18 related calls were logged from the provinces of the Western Cape, Eastern Cape, Kwazulu-Natal and the Northern Cape collectively. During the same period, 23 calls were logged at the call centre for incidents happening in the inland provinces.
According to Peter Feurstein, Netcare 911’s Regional Coastal Operations Manager, many of the calls received from the coastal provinces, involving children, resulted from freshwater sources such as public and private swimming pools, rural dams and rivers. There is also a noticeable trend in terms of the age differences of the children involved in these incidences.
“There seems to be a definite distinction between inland and coastal incidents. Coastal incidents seem to be involving the age group of 10 to 18 year-olds more predominantly whilst, inland, the greatest number of incidents involve the 2 to 8 year-old age bracket,” says Feurstein.
Nick Dollman, a safety officer and spokesperson for Netcare 911’s incident management unit in Gauteng, confirms the alarming statistics being shown through this trend: “In Johannesburg alone, Netcare 911 has attended to 17 victims including fatal drowning and near drowning emergencies, since 1 December. 12 of these involved children under the age of 10, two were teenagers and three adults.”
Feurstein believes that this trend can be explained by the fact that warning campaigns about water safety are seemingly more adhered to, as well as the heightened sense of awareness, in the coastal areas. During last year’s holiday season, for instance, the Vodacom Netcare 911 Surf Rescue Service where five helicopters were made available to volunteer rescue workers from the National Sea Rescue Institute (NSRI), Lifesaving SA and Netcare 911.
Dollman agrees, especially as his team in Gauteng have picked up on the fact that most of the drowning incidences they have been called out to involved the children of people who are not used to being around swimming pools.
He explains: “These past two weeks we attended to several children of domestic workers who had drowned, or nearly drowned, at their parents’ place of work. Some of these children are from other provinces and come to visit their family for the holidays and are not familiar with swimming pools or the hazards that lie within. Interestingly, as many of the employers do not have small children themselves, their pools are not protected, which leads to avoidable tragedies.”
But swimming pools, even those where permanent lifeguards are on duty, are not the only places where children can easily drown. 90% of children who drown are under some sort of supervision at the time.
Dollman warns that a small child can easily drown in only a few hundred millimetres of water. “We have even attended to a child who had fallen into a large plastic bucket that was being used to clean nappies. Parents and childminders should be aware of all the water hazards in and around the home, including fishponds, water features, toilets, pets’ water bowls, bore holes and open drains.”
One of the scariest statistics is that, for every child that dies from drowning, five are left with permanent brain damage as a result of the prolonged lack of oxygen which occurs during a near drowning. It takes only four minutes without oxygen for irreversible brain damage to occur.
Drownings are listed as one of the top causes of unnatural death amongst children in South Africa. At the same time, these unfortunate events are very preventable. Should you find yourself in the position of having to call for help, please call Netcare 911 immediately on 082 911.
Additional notes on preventing drownings:
Prevention is better than cure. Be vigilant and keep a watchful eye on the children around water, keep pool gates locked or cover your pool with a certified pool net. A basic course in first aid and CPR can make a dramatic difference in the outcome should the skills be applied timeously.
For further information on the courses available, please contact the Netcare 911 School of Emergency and Critical Care on 011 695 9600, visit the Netcare 911 website or consult your local yellow pages under the "first aid" heading for a comprehensive list of training facilities. Ensure that you use an accredited facility and receive a certificate of competence.
In any emergency situation the most important thing to do is immediately contact the correct emergency number for the relevant authority. Try and memorise the number for emergency services in your area and keep the number saved on your cell phone or close to your landline telephone. In many cases, during the panic of a medical emergency, people cannot remember the correct number or cannot find where they have written it down. Otherwise contact Netcare 911 on their national number: 082 911
In the event of a drowning, the following assistance interventions are recommended:
Having multiple layers of safety around pool and spa areas or other open bodies of water (such as a safety net, a closed fence, a childminder and a surface alarm) can prevent tragic accidents.
Get the victim out of the water as soon as possible, but do not become a victim yourself. Make sure it is safe for you to enter the water first.
Handle the victim with care. Many submersion incidents are associated with neck injuries, so keep movement to the back and neck to a minimum.
Assess to see if the victim is awake or not.
Check for breathing. If the victim is not breathing, administer two slow rescue breaths, ensuring that the victim’s chest JUST starts to rise.
If the victim shows no response to the rescue breaths, start CPR.
CPR is vital, even if it is an amateur administering it. Keep on doing it until someone who is trained in advanced life support arrives and can take over. All parents should learn how to administer child CPR as it does differ from adult CPR. There has also recently been a worldwide revision in the CPR technique and it is vital that even current first aiders be retrained according to the new protocols.
Call, or have someone call, a recognised ambulance service as early as possible during this sequence. Whoever calls for the ambulance must give the dispatcher an accurate location of the incident and a contact number at the scene. Never hang up on the operator and always return to the rescuer to inform them that you have called for help

Cardiac Arrest CPR

The Science:

Researchers in England were concerned with the potential impact that performing compression-only CPR would have on ventilation. They acknowledge the science supporting the vital importance of uninterrupted chest compression but wondered whether they could measure the amount of air that was moved in and out of an intubated cardiac arrest patient and from that decide whether this amount of passive ventilation was sufficient to oxygenate the lungs.

idm_defibrilationThis study examined the outcomes of 738 cardiac arrest victims who presented with an initial rhythm of pulseless electrical activity (PEA) or asystole. Both are considered "Non-shock" rhythms, and the primary treatment is CPR and medication. If the patients developed V Fib or V Tach "shock" rhythms, then they were defibrillated.

The Science:

I don't usually comment on science reported only in editorial remarks. However, this correspondence in the Journal of the American College of Cardiology caught my attention because it was only this past year that I and several other “experts” were asked whether we believed in any benefit from reduced dose fibrinolytics being administered by EMShe data presented was from a pilot trial of an on-going wider study. The question is, "Does the administration of a half-dose of retaplase by EMS significantly affect the time to reperfusion and subsequent angiographic perfusion scores when compared to fibrinolysis alone, primary coronary intervention (PCI) instead of EMS retaplase, or in combination with PCI?"
