What is cryomodulation and nanosecond pulsed electric field treatment?


October 14th, 2020 | General Info

Cryomodulation and nanosecond pulsed electric field treatment are two new technologies for the treatment of benign lesions like seborrheic keratoses. Cryomodulation is a technique using cooling technology to treat sunspots and seborrheic keratoses. The first to market device is Glacial RX by R2 Technologies.

Another new technology is nanosecond pulsed electric field treatment, which is a nonthermal, energy based technology used to treat seborrheic keratoses and other conditions. It will be interesting to see how effective these two new technologies will be.

Needle Size May Affect Soft Tissue Filler Properties


October 14th, 2020 | General Info

A recent article in Dermatologic Surgery suggests that injectors (and patients) should be aware of the effects of needle size on the properties of fillers. Various types of fillers (monophasic and biphasic) were injected through 30G needles and the size and properties of the fillers were analyzed after they had been injected through the needles.  

Both monophasic (e.g. Juvederm products) and biphasic (e.g. Restylane) fillers were affected by the smaller needle size. They were affected in terms of the size of the extruded particles and in the properties (G’) of the extruded particles. Interestingly, biphasic fillers seemed to be affected more than monophasic fillers. In addition, larger particles seemed to be affected more than smaller particles as we would intuitively expect. 

Injectors should consider the size of the needle being used to inject fillers (especially biphasic fillers and fillers of larger particle size) as this might affect the performance and durability of the filler.

Nuceiva–the Newest Botulinum Toxin on the Market


October 4th, 2020 | General Info

Nuceiva Edmonton

Nuceiva is the newest neuromodulator on the market for the treatment of glabellar frown lines. Whereas Botox is referred to as abobotulinumtoxin A, Nuceiva is referred to as prabotulinumtoxin A.

Similar to other brands such as Botox, Xeomin, and Dysport, Nuceiva™ works to smooth out creases in the face by decreasing muscle contraction.

It has been approved by Health Canada and the FDA.

Marketed as Jeuveau by a company called Evolus in the United States, it originated with a South Korean company called Daewoong. Nuceiva™ was authorized for sale by Health Canada in August of 2019 and was subsequently officially brought to the Canadian market by Clarion Medical Technologies in October 2019. It is also available in the European Union.

Nuceiva™ usually lasts about 3 to 4 months although this varies from person to person. A study published in Dermatologic Surgery in 2019 showed similar efficacy to Botox.

The Latest on Bleach Baths for Eczema


July 14th, 2020 | General Info

eczema bleach baths

Bleach baths are a controversial therapy for patient with atopic eczema, also known as atopic dermatitis (AD). In recent years, there has been an increase in the use of bleach baths to decrease the severity of the eczema. However, a recent review showed that while bleach baths did seem to decrease the severity of atopic eczema, it was no more effective than water baths alone. There has been a lot of research into the effect of bleach baths on Staphylococcus bacteria and it seems like the concentration of bleach used in bleach baths may not be high enough to kill bacteria. There may be other anti-inflammatory properties that have yet to be discovered.

With all of the conflicting data out there, the best summation is probably what was stated in the latest Canadian consensus statement on pediatric atopic eczema: “bleach baths have not been consistently shown to improve outcomes in AD and may be used at the discretion of the treating health care provider.”

Effect of Topical Anesthetic Prior to Laser Treatment for Blood Vessels


July 4th, 2020 | General Info

Pulsed dye laser (PDL) is a very effective treatment for redness of the face due to enlarged blood vessels. It has proven to be very safe and effective. However, there is some discomfort from the laser pulses and while most patients have no difficulty tolerating treatment without any anesthetic, some patients do find it difficult to tolerate. Topical anesthetic can be used to decrease the discomfort of laser treatments but there has always been the question of whether the vasoconstrictive properties (i.e. constriction of blood vessels) of the anesthetic might have an adverse effect on outcome if you are trying to get rid of blood vessels.

A recent study by Chunharas et al in April of 2020 (Lasers Surg Med. 2020 Apr;52(4):307-314) demonstrates that topical anesthesia with lidocaine and tetracaine do not interfere with the efficacy of pulsed dye lasers. This is great news for those who want to receive treatments with pulsed dye lasers.

Prabotulinumtoxin A: a new type of Botox?


May 13th, 2020 | General Info

Prabotulinumtoxin A

In 2002, Botox (onabotulinumtoxin A) was the first botulinum toxin to gain FDA approval for the “temporary treatment of glabellar lines in adults.”  A recent study published in Dermatologic Surgery reviewed two Phase 2 randomized, multicenter, double-blind, placebo controlled trials with 2100 patients showed that a new version called prabotulinumtoxin A had a similar onset of action, duration of action, and adverse event profile as compared to Botox. On the market currently, we have Botox, Dysport, and Xeomin for the treatment of lines and wrinkles. We may see another agent available soon.

Surgical and Procedure Masks

Putting on masks is something new to many people. In this era of COVID-19, social distancing, and trying to avoid spreading the virus to each other, masks may be one additional layer of protection. It is by no means 100% effective but if it does seem to reduce risk.

I have put together a video on how to apply these masks safely. If you know someone who might benefit from a simple overview, please send this on to them. In addition, I have an infographic on masks that I think is informative. Unfortunately, our blog only displays small thumbnails and I need to contact our web designers to change this before I post it. Stay tuned. Hopefully by next Tuesday I will post the infographic.

Temporary Closure due to the COVID-19 Public Health Emergency


March 18th, 2020 | General Info

covid-19 closureTemporary Closure

On Monday, March 16, 2020, the Nakatsui DermaSurgery Centre decided to take a leading initiative and temporarily close operations to help mitigate the spread of COVID-19. This was not an easy decision. In the end, we are confident that this was the best decision to protect our patients, our staff, and our community. We have stopped all non-essential services and are in the process of contacting patients who were scheduled to see us in the next two weeks to let them know what is happening. We will do our best to reschedule everyone as soon as possible once the situation improves. For our current patients who have more urgent medical needs, Dr. Nakatsui will make himself available to see you.

It is important to remember we should not panic as this infection will be well managed for the vast majority of those affected. However, we must assist our health care system by “flattening the curve” and preventing the exponential rise in COVID-19 and reducing the number of serious cases.

We will still be answering our phones and responding to emails for the time being. If you have any questions and concerns, please feel free to contact us at 780-482-1414 or via email at [email protected].

Clean Cyst Removal

Sebaceous Cyst Removal

In this video, Dr. Nakatsui removes a sebaceous cyst from our patient’s scalp. The cyst came out whole, cleanly, and intact! Many times, if a cyst becomes infected it can adhere to the surrounding tissue making extraction trickier as it can fragment and stick to surrounding tissue.

Overall a great little surgery which great end results!

Sebaceous Cyst Removal


September 28th, 2019 | Treatments, Video

In this video Dr. Nakatsui is removing two sebaceous cysts located on the scalp. Our lovely patient graciously allowed us to film the procedure and we thank you for that!

In this video the two cysts come out relatively easily and intact as a whole. There will be several instances where we are not so lucky and the cyst may fragment or it may adhere to surrounding tissue more making extraction more difficult.

Sebaceous cysts may occur anywhere on the body at any time of our lives. They are generally not life-threatening, but when concerned about any lesion, it is always best to seek medical attention. Many patients with sebaceous cysts may leave them as they generally will not bother them. From time to time, cysts may become inflamed, painful, produce discharge, or become infected. If a cyst has had repeated infection/inflammation or self attempts to extract the contents by squeezing the cyst, this is when the cyst wall may become more adherent to surrounding tissue making it difficult to extract.

Should a cyst develop, it is advisable not to perform self surgery as any tools used to puncture the skin or extract the cyst may push unwanted bacteria into the site causing an infection. Not only that, if the wound site is not properly closed or should become infected, when it fully heals you may be left with an unwanted scar which may be difficult to treat in the future.

Blood Vessel (Telangiectasia) Treatments


September 24th, 2019 | Conditions

Broken blood vessels, or telangiectasias, are a very common and typically non-threatening condition that can affect any part of the body. Telangiectasias can naturally arise at any time, however, individuals that have chronically exposed their skin to the sun or extreme temperatures may be more susceptible to telangiectasias. 

For the majority of times, once a telangiectasia appears, it rarely if ever goes away on it’s own. Over time people may notice an increase in these broken blood vessels. Usually most people do not care if the telangiectasia appears on their arms, legs, or torso as it can be easily covered; however, once they become more apparent on the face and neck, then it becomes more of a cosmetic concern.

The typical treatment for telangiectasias at our centre involves the use of a laser called the V-Beam pulsed dye laser. This laser uses a specific wave length of light to destroy the hemoglobin in the red blood cell, which is predominantly what is seen in telangiectasia. The energy is absorbed by the hemoglobin and bursts the cell. Once the treatment is complete, the body reabsorbs the vessel. Because the laser is physically bursting the vessel, a bruise may become evident which can last for approximately 5-10 days. 

The treatment is fairly quick and has relatively low pain associated with it. Most of our patients say that it is similar to a rubber band being snapped onto your skin. It is advisable that should you go for a V-beam pulsed dye laser treatment (or all lasers for that fact), it is important to do your best to avoid excessive sun exposure before and after the treatment for as long as possible.

SPF — Higher really is better


July 28th, 2018 | General Info

spf sunburned man edmontonA recent study on SPF published in the Journal of the American Academy of Dermatology (JAAD, 2018; 78: 902-910) demonstrates that higher sun protection factor sunscreens really do provide additional benefit. This study evaluated skiers in a double-blind, split-face, randomized study. In this study, skiers in Vail, Colorado wore SPF 50 on one side of the face and SPF 100 on the other side of the face. They were allowed to do their normal activities and were then evaluated the next day to see if there was any evidence of sunburn erythema. The SPF 100 sunscreen side was found to be significantly more effective in protecting against sunburn.
The study supports our belief that if you are going to be out in a lot of sun, the higher the sun protection factor, the better! Another factor that may be important is that many of us apply far less sunscreen than we should, so you might think you are getting an SPF 50. However, you might be applying such a thin layer that you are only getting the equivalent of SPF 20! Consequently, make certain you apply enough sunscreen to provide adequate protection and if you decide to go to a higher sun protection factor,

Let’s talk about scars


July 27th, 2018 | General Info, Treatments, Uncategorized

Scar treatmentScar treatment can be challenging and requires a multi-dimensional approach in order to be successful. A scar can be the centre of attention but can also be a source of annoyance. For some individuals, scars are a part of who they are, whereas for others they are intrusive and cause insecurity. They can be caused by a variety of reasons such as acne scarring, trauma, and surgery.

Some individuals have thickened keloid scarring, where a scar becomes raised and discoloured. In order to treat the thickened aspect of the scar, many times cortisone injections will be utilized to reduce the thickness of the scar.

On the opposite end of thickened scars, people may get pitted scars where the skin sinks in various regions. These types of pitted scars can be tricky to treat; however, with improvement in technologies and techniques, pitted scars can often be improved. In some cases, Dr. Nakatsui will use an ablative laser to smooth out the skin and reduce the harsh edges that cause shadowing.

A new approach is to promote collagen re-growth in the region.  Through the use of a technology called Percutaneous Collagen Induction (PCI), many tiny needles create tiny holes in the skin. The creation of these tiny holes stimulates collagen formation to help fill in the areas of depressed scarring.
