Differentiating Between Anxiety, Syncope & Anaphylaxis
Differentiating between anxiety, syncope & anaphylaxis Dr. Réka Gustafson Medical Health Officer Vancouver Coastal Health Introduction Anaphylaxis is a rare but much feared side-effect of vaccination. Most vaccine providers will never see a case of true anaphylaxis due to vaccination, but need to be prepared to diagnose and respond to this medical emergency. Since anaphylaxis is so rare, most of us rely on guidelines to assist us in assessment and response. Due to the highly variable presentation, and absence of clinical trials, guidelines are by necessity often vague and very conservative. Guidelines are no substitute for good clinical judgment. Anaphylaxis Guidelines • “Anaphylaxis is a potentially life-threatening IgE mediated allergic reaction” – How many people die or have died from anaphylaxis after immunization? Can we predict who is likely to die from anaphylaxis? • “Anaphylaxis is one of the rarer events reported in the post-marketing surveillance” – How rare? Will I or my colleagues ever see a case? • “Changes develop over several minutes” – What is “several”? 1, 2, 10, 20 minutes? • “Even when there are mild symptoms initially, there is a potential for progression to a severe and even irreversible outcome” – Do I park my clinical judgment at the door? What do I look for in my clinical assessment? • “Fatalities during anaphylaxis usually result from delayed administration of epinephrine and from severe cardiac and respiratory complications. “ – What is delayed? How much time do I have? What is anaphylaxis? •an acute, potentially -

Egg Allergy: the Facts
Egg Allergy: The Facts Egg is a common cause of allergic reactions in infants and young children. It often begins in the child’s first year of life and in some cases lasts into the teenage years – or even into adulthood for a few people. Children who develop allergy to foods such as egg often have other allergic conditions. Eczema and food allergy often occur in early infancy and later on there may be hay-fever, asthma or both. This Factsheet aims to answer some of the questions which you and your family may have about living with egg allergy. Our aim is to provide information that will help you to understand and minimise risks. Even severe cases can be well managed with the right guidance. Many cases of egg allergy are mild, but more severe symptoms are a possibility for some people. If you believe you or your child is allergic to egg, the most important message is to visit your GP and ask for allergy tests and expert advice on management. Throughout this Factsheet you will see brief medical references given in brackets. If you wish to see the full references, please email us at [email protected]. Symptoms triggered by egg The symptoms of a food allergy, including egg allergy, may occur within seconds or minutes of contact with the culprit food. On occasions there may be a delay of more than an hour. Mild symptoms include nettle rash (otherwise known as hives or urticaria) or a tingling or itchy feeling in the mouth. More serious symptoms are uncommon but remain a possibility for some people, including children. -

Vaccines 101 the Very Last Day That I Was a Pediatric Resident. Um, Many
Vaccines 101 The very last day that I was a pediatric resident. Um, many years ago, a toddler walked into the emergency room and uh, and progressively got sicker and sicker. That's Dr. Katherine Edwards, a world expert in pediatric infectious disease in vaccinology. She's also a professor of pediatrics at Vanderbilt university and she's been working on vaccines for 40 years. I did a spinal tap on her and realized that she had Haemophilus influenza, typ e B meningitis, Haemophilus influenza, type B or HIB is it bacteria normally found in our nose and throat that can lead to very serious life threatening infections and no matter what I did in that day and into the night in terms of prompt antibiotics and she'd just been sick a few hours and, and fluids and all the, you know, ventilators and all the best things that modern medicine, she died, the vaccine for hip was not available until the 1990s. And until it did become available, hip disease affected approximately 25,000 children each year with things like meningitis, pneumonia, and bloodstream infections. And at that time in the hospital that I was practicing at any one time, there were generally five or six patients that had Haemophilus meningitis or invasive disease or some complication of this particular infection. And we knew that from the basic science that if you had antibody to the capsule or to the coat of the organism, that you were protected from disease. But we really didn't know how to make little kids make antibody. -
Vaccines for Preteens
| DISEASES and the VACCINES THAT PREVENT THEM | INFORMATION FOR PARENTS Vaccines for Preteens: What Parents Should Know Last updated JANUARY 2017 Why does my child need vaccines now? to get vaccinated. The best time to get the flu vaccine is as soon as it’s available in your community, ideally by October. Vaccines aren’t just for babies. Some of the vaccines that While it’s best to be vaccinated before flu begins causing babies get can wear off as kids get older. And as kids grow up illness in your community, flu vaccination can be beneficial as they may come in contact with different diseases than when long as flu viruses are circulating, even in January or later. they were babies. There are vaccines that can help protect your preteen or teen from these other illnesses. When should my child be vaccinated? What vaccines does my child need? A good time to get these vaccines is during a yearly health Tdap Vaccine checkup. Your preteen or teen can also get these vaccines at This vaccine helps protect against three serious diseases: a physical exam required for sports, school, or camp. It’s a tetanus, diphtheria, and pertussis (whooping cough). good idea to ask the doctor or nurse every year if there are any Preteens should get Tdap at age 11 or 12. If your teen didn’t vaccines that your child may need. get a Tdap shot as a preteen, ask their doctor or nurse about getting the shot now. What else should I know about these vaccines?
