Seeing Stars

 


Why do you see stars when you bump your head? Seeing stars or bursts of light is common after a bump on the head. These "stars" you see are neurons on the visual cortex firing spontaneously.

This happens inside the skull, where there is extra room for the brain to move backward and forward. When you get a bang on the head, your brain is suddenly accelerated, shaking the brain, this causes blood sloshing blood into or out of the capillaries abruptly changing oxygenation levels. The back-and-forth motion in the skull also affects the occiput. The occiput is the section of the cranium that is located at the rear of the skull and contains tissues responsible for communicating nerve impulses going into the eyes and the rest of the body.

In most cases, this is no cause for concern. There is cause for concern when the stars don't go away after a short period or return. If you have these other symptoms, you should get to the ER:

• Headache

• Problems concentrating

• Memory

• Balance

• Coordination

• Loss of consciousness

• Confusion

• Ringing in the ears

• Nausea and vomiting

• Fatigue and drowsiness

• Blurry vision

• Slurred speech

• Personality changes

• Sensitivity to light and noise

• sleep disturbances

• Seizures

Seeing-Eye Dogs

 

Image: https://www.seeingeye.org

Guide dogs are more commonly known as seeing-eye dogs. These dogs are trained to lead a person who is blind or visually impaired around obstacles.

Seeing-eye dogs are not like GPS. It is the dog's job to look out for hazards and obstacles that someone who is blind cannot detect.

Guide dogs are very carefully paired with their handlers. When someone applies to get a guide dog many things are taken into consideration for the person's happiness as well as the dog's happiness:

  • Lifestyle
  • Hobbies
  • Activity level
  • Family
  • Living arrangements
  • Other pets

There are no strict rules for what breed of dogs can be used for guide dogs. Pups need to have the right temperament and trainability. Trainers know what to look for. Dogs that aren't easily distracted or high strung and are easily trainable.

Certain breeds are chosen more than others:

  • Labradors
  • German shepherds
  • Golden retrievers
  • Border collies
  • Standard poodles
  • Labradoodles (are chosen for people with allergies)

These dogs are specially bred and trained for these important jobs. There are guidelines people should follow when in the presence of a guide or service dog to allow for the safety of the dog and its handler. Disregarding these guidelines can distract the dog, which can create a dangerous situation for the team.

Dos and don'ts for people interacting with Guide dogs:

Don’ts

  • DON’T try to get a guide dog’s attention when his harness is on. When their harnesses are on, they’re hard at work. Don’t pet them, play with them or feed them treats unless their handlers give you specific permission to do so.
  • DON’T interfere when a guide dog’s handler is giving a correction. Service dogs are highly trained, but sometimes they make mistakes! Corrections might seem abrupt and startle a guide dog, but you can rest assured that the handler has also been properly trained in giving corrections and that he or she would never do anything to hurt the dog.
  • DON'T assume a napping service dog is off duty. All dogs nap, including working dogs. When his or her handler is sitting or standing for some length of time, it's perfectly natural and appropriate for a service dog to catch a few winks. The dog is still technically at work, however, so all dos and don'ts remain in effect.
  • Don’t allow your child to approach a service dog.
  • DON'T assume service dogs never get to 'just be dogs'. Working dogs typically get plenty of R&R and playtime. When they're home and out of their "work clothes," they're free to behave like any other dog. Since the jobs these wonderful animals do are often challenging and stressful, their handlers recognize they need plenty of downtime and exercise.

Dos

  • DO keep other pets on a leash and close to you when you’re near a guide dog team. Dogs will be dogs, and even the best-trained service dog may want to play with yours — so it’s best just to walk on by.
  • DO trust the guide dog. If you’re in a nearby car when a team arrives at an intersection, give the dog the benefit of the doubt that they’ll be able to get their charge across the street without incident. Honking or yelling out the window will do nothing but distract!
  • DO speak to the owner/handler rather than the dog. The service dog and the handler are a team. If you want to talk to them, always speak to the person first rather than automatically approaching the dog. Remember, the animal is working and the life of the dog and handler depend on the dog being focused.
  • DO treat the owner/handler with sensitivity and respect.

Your Childs First Pair of Glasses

 


Maybe it was the teacher sending a letter home, a trip to the pediatrician or you noticed some of the signs-holding a book very near his or her face, squinting, or complaining of headaches. Maybe your child even told you themselves they can't see the board at school. Whatever the case your child needs an eye exam and possibly to start wearing glasses. A child may need glasses as young as a few months of age, but usually between the ages 6 to 12 years.

Prepare your child for their first pair of glasses by:

  1.  Explain have glasses will improve vision - You must explain to your child how glasses will improve their vision by providing examples of the challenges of their poor vision. If your child needs to sit close to the TV to see, explain that glasses will allow them to sit comfortably on the couch to enjoy their favorite TV show or movie.
  2. Show your child examples of people who wear glasses. If there is one person who your child adores and wears glasses, make this connection for them. Celebrities, athletes, or even fictional characters like Harry Potter or Velma from Scooby-Doo.
  3. Tell them what to expect at their eye exam. Fear of the unknown can scare adults, and children are no different. If you are due for your own annual eye exam, you might consider booking an appointment time immediately before, so your child can see what happens. That gives you and the doctor to talk about what each machine measures and why those measurements are important.
  4. Visit the eye doctor

Tips for your child’s first pair of glasses:

  1. Let your child choose their frames-Make it fun. The biggest piece of advice is to let your child decide which frame they like best. When they select their favorite frame, they start to feel a sense of ownership and pride in their choice. They'll be the ones wearing them every day, and the transition to daily wear will be a little smoother if they've got a pair they really like.
  2. Getting the right fit-An improper fitting could not only make the glasses uncomfortable but also impair your child from looking through the optical center of the lens.
  3. Be pro-glasses-They’re going to take their cues from you about how to feel about it, so put your most positive face forward.
  4. Set goals and take your time-For some kids, wearing glasses all day will take a little time. Start slowly wearing them for maybe an hour here and there, then two hours, etc... Until your child can wear them all day.
  5. Adjustment period-some children quickly adapt to their new glasses, a transition with a few uncomfortable side effects may be expected. Remember, these symptoms are normal and aren’t cause for alarm. However, if you are concerned, contact your eye doctor for guidance.
Teach your child proper eyeglass care-Teach your child how to correctly clean the lenses (always use a soft cloth made for lens cleaning) and how to safely store glasses in a case when they’re not in use. Especially with younger children, it’s normal for them to forget to clean their glasses and then feel unhappy about seeing blurry images due to smudged lenses. Teach them to take their glasses off and put them on with two hands so the arms aren’t over-extended. Patiently teach and remind your child to care for the glasses until this becomes a natural habit

World Hand Hygiene Day

 


World Hand Hygiene Day takes place on May 5th, 2022. It is a day dedicated to advocating for handwashing with soap and water as an easy, effective, and affordable way to prevent diseases and save lives. This day is declared by the World Health Organization (WHO). Regular handwashing is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others whether you are at home, at work, traveling, or out in the community.

Why does handwashing prevent illness?
  • People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through the eyes, nose, and mouth and make us sick.
  • Germs from unwashed hands can get into foods and drinks while people prepare or consume them. Germs can multiply in some types of foods or drinks, under certain conditions, and make people sick.
  • Germs from unwashed hands can be transferred to other objects, like handrails, tabletops, or toys, and then transferred to another person’s hands.
  • Removing germs through handwashing therefore helps prevent diarrhea and respiratory infections and may even help prevent skin and eye infections.

Key Times to Wash Hands

You can help yourself and your loved ones stay healthy by washing your hands often, especially during these key times when you are likely to get and spread germs:
  • Before, during, and after preparing food
  • Before and after eating food
  • Before and after caring for someone who is sick with vomiting or diarrhea
  • Before and after treating a cut or wound
  • After using the toilet
  • After changing diapers or cleaning up a child who has used the toilet
  • After blowing your nose, coughing, or sneezing
  • After touching an animal, animal feed, or animal waste
  • After handling pet food or pet treats
  • After touching garbage
Steps to washing your hands properly
  1. Wet your hands with clean — preferably running — water.
  2. Apply enough soap to cover all surfaces of your hands and wrists.
  3. Lather and rub your hands together briskly and thoroughly. Make sure to scrub all surfaces of your hands, fingertips, fingernails, and wrists.
  4. Scrub your hands and wrists for at least 20 seconds.
  5. Rinse your hands and wrists under clean — preferably running — water.
  6. Dry your hands and wrists with a clean towel, or let them air-dry.
  7. Use a towel to turn off the faucet.
Handwashing helps battle the rise in antibiotic resistance. Preventing sickness reduces the number of antibiotics people use and the likelihood that antibiotic resistance will develop. Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. If antibiotics lose their effectiveness, then we lose the ability to treat infections and control these public threats.

There are lots of contaminants out there you come in contact with. Using hand sanitizer helps, but doesn’t replace washing with soap and water. There are important differences between washing hands with soap and water and using hand sanitizer. Soap and water work to remove all types of germs from hands, while sanitizer acts by killing certain germs on the skin. Although alcohol-based hand sanitizers can quickly reduce the number of germs in many situations, they should be used in the right situations. Soap and water are more effective than hand sanitizers at removing certain kinds of germs. Hand sanitizers also may not remove harmful chemicals, such as pesticides and heavy metals like lead from the skin.
