Frequently Asked Questions

-many different types of biopsies:  shave, punch, curette

-done to make a diagnosis not necessarily to completely remove lesions

-why is it necessary to have a biopsy?  Can’t it wait until after COVID?

Ever wonder what that little tool is that the dermatologist peers at your skin with, and why can’t you just use your own two eyes?

Dermoscopy is the non-invasive examination of the skin using a medical tool called a dermatoscope – which is the dermatologist’s equivalent of a stethoscope.  Essentially, a dermatoscope is a lit magnifying glass, often with polarized lenses that allows your dermatologist to view the microscopic subsurface of skin structures and at least 30 different features that are otherwise not visible to the naked eye.  Dermosopy significantly improves diagnostic accuracy and using a dermatoscope can differentiate most skin lesions from melanoma.  Using a dermatoscope allows your dermatologist to quickly scan over many lesions as well as carefully examine detailed skin surfaces for unusual or red-flag characteristics.

That all sounds interesting but, does it DO anything?

Although it’s a pretty amazing medical tool, it doesn’t have any flashing lights and doesn’t make any sci-fi sounds.  All of the magic of the dermatoscope comes from the specialist wielding it in their hands.  The flash and bang of the dermatoscope comes directly from your dermatologist who knows just how to interpret all the information gathered from the tool.

Where do I get one of those?

Dermoscopy often involves an algorithm, however, there is also a subjective element, or artistry, to using a dermatoscope that comes with years of intensive training and experience examining thousands of cases. Best leave this to your dermatologist!

The short answer, YES!  Any good dermatologist will always recommend using sunscreen.  Just like clothing does not fully protect against the sun, neither do facial masks.  All the same rules apply.  Be sure to apply sunscreen every day with a minimum SPF of 30.  Unless you are riding out the COVID-19 pandemic on a beach, in a pool or training for a triathlon, you won’t need a waterproof sunscreen, but if that’s all you have, put it on!  If you are wearing makeup (and why shouldn’t you feel your best, even during quarantine?) put it on AFTER you apply your sunscreen, or better yet, purchase a foundation that has an SPF 30 or higher already in it.  Allow a minimum of 15-20 minutes before donning your masks, to prevent it from transfering from your face to your mask.  Remember to reapply your sunscreen if you are planning to spend time outdoors without your mask on.

With all the extra hand washing and hand sanitizer use these days, you might be suffering from dry skin.  Since you are unlikely to stop using harsh soaps and sanitizers during COVID-19, it’s time to think about adding some moisture back into that hard-worn skin.  There is no single magical cream for everyone, and you certainly don’t need to break the bank.  The best cream for dry skin is one that you will use regularly.  It is always a good idea to avoid harsh fragrances which can be irritating and promote inflammation and itch of the skin, but let’s face it – everyone has different preferences for texture and feel.  So once you find a moisturizer you like, stick with it and apply often!  If even your favourite cream can’t soothe your dry skin, you might need something stronger from your dermatologist.

It is understandable that those of you on immune-suppressing medications may have concerns about continuing these drugs amidst the threat of COVID-19.  The general consensus is that if you do not have any symptoms of COVID-19 and are stable on your immune-suppressing medication, you should continue it and not stop abruptly.  Continue to get your blood work as scheduled by your dermatologist or rheumatologist.  If you are experiencing flu-like symptoms or think you may have COVID-19, you should stop using your immune-suppressing medication and consult your prescribing physician.   Ultimately, the best person to consult about this choice is the physician who prescribed it for you.

A dermatology physician assistant is a highly trained healthcare professional that collaborates with the dermatologist to examine, test and treat patients.  Dermatology PAs are trained as generalists in the medical model and receive specialized training in dermatologic, surgical, and sometimes aesthetic practices as part of their practical training and in-clinic from their supervising dermatologist. The scope of practice for a derm PA corresponds directly to the dermatologist’s scope of practice.  In general, a PA will see many of the same types of patients as the physician and provide a broad range of healthcare services that are often the same as you might receive from your physician, including obtaining a medical history, conducting a skin survey, administering injections, conducting skin biopsies, and prescribing medications, among other services.

Not every dermatologist employs a physician assistant, however the addition of PAs to dermatology practices have been shown to reduce wait times and increase accessibility to dermatologic care.

Telemedicine refers to the practice of caring for patients remotely through telephone and/or video conferencing platforms when the health care professional and patient are not physically present with each other.  This is especially useful now, during this time of  COVID-19 social distancing and quarantine, when your doctor’s office may be closed to non-urgent medical conditions.  Telemedicine gives you access to your healthcare provider so that you can continue to receive comprehensive medical care including assessment, diagnosis and treatment.

Telemedicine is not a new concept.  It has been a very successful means of extending care to under-serviced and remote areas where patient access to physicians is limited.

Sounds amazing, but who pays for all this?

The option of telemedicine between a patient and their physician is currently covered in Ontario by OHIP in order to extend care to patients during this time of social distancing.

  • Both PAs and NPs graduate from accredited programs The PA training model is based on the medical model, which is the same model physicians learn from. NP training is based on the nursing model, which has a different philosophy and focus than the medical mod. However each are trained in assessments, differential diagnosis and critical thinking skills.
  • PAs and NPs are considered non-physician health care practitioners
  • Both PAs and NPs provide direct patient care.
  • Both PAs and NPs can prescribe. PAs prescribe under medical directives in Ontario, whereas NPs have a broad prescription formulary from which they prescribe
  • PAs are trained as generalists and can work in any field of medicine. NPs do not switch specialties (there are four tracks in Ontario – NP-primary care, NP-adult medicine – NP-paediatrics, NP-anesthesia).
