Practical Pearls

What does your patient need to know at the first visit?  

All patients, regardless of race, gender, or age, are afraid of an alopecia diagnosis. Often, the first thing a patient may say when I enter the examination room is, "Please don't tell me I have alopecia."  

The first step to a successful initial visit for hair loss is addressing the angst around the word alopecia, which helps to manage the patient's hair-induced anxiety. The next priority is setting expectations for the journey including what to expect during the diagnosis process, treatment, and beyond.  

Next is data collection. An extensive hair care practice investigation can begin with a survey that the patient fills out before the visit. Dive into and expand on hair loss history questions, including medical history as well as hair care practices (eg, history of use, frequency, number of years, maintenance for that particular hairstyle) such as braids (eg, individual braids, cornrow braids, with or without added synthetic or human hair), locs (eg, length of locs), chemical relaxers (eg, number of years, frequency, professionally applied or applied at home), hair color, weaves (eg, glued in, sewn in, combination), and more.¹ Include a family history of hair loss, both maternal and paternal.  

The hair loss investigation almost always includes a scalp biopsy, hair-pull test, dermoscopy, photographs, and even blood work, if applicable. Scalp biopsies may reveal more than one type of alopecia diagnosis, which may impact the treatment plan.² Sending the scalp biopsy specimen to a dermatopathologist specializing in alopecia along with clinical information about the patient is preferred. 

What are your go-to treatments?  

My go-to treatments for patients with skin of color (SOC) and hair loss really depend on the specific diagnosis. Randomized, placebo-controlled clinical trials focusing on treatment are lacking in central centrifugal cicatricial alopecia and traction alopecia, which holds true for many other types of alopecia.  

For black patients with central centrifugal cicatricial alopecia, I often address the inflammatory component of the disease with oral doxycycline and either a topical corticosteroid, such as clobetasol, or intralesional triamcinolone. Adding minoxidil-containing products later in the treatment process can be helpful. Various treatment protocols exist but are mainly based on anecdotal evidence.¹ 

For those with traction alopecia, modification of offending hairstyle practices is a must.³ Also, treatment of inflammation is key. Typically, I gravitate to topical or intralesional corticosteroids, followed by minoxidil-containing products. However, a challenge of treating traction alopecia is changing the hair care practices that cause tight pulling, friction, or pressure on the scalp, such as from the band of a tightly fitted wig.  

It is important to discuss potential side effects of any treatment with the patient. For the most common side effects, discuss how to best prevent them. For example, because of the photosensitivity potential of doxycycline, I ask patients to wear sunscreen daily. To prevent nausea, I recommend that they avoid taking doxycycline on an empty stomach, drink plenty of fluids, and avoid laying down within a few hours after taking the medication.  

How do you keep patients compliant with treatment? 

Dermatologists should try to understand their patients' hair. A study of 200 black women demonstrated that 68% of the patients did not think their physician understood their hair,⁴ which likely impacts patients' perceptions of their physician, confidence in the treatment plan, and even compliance with the plan. Attempting to understand the nuances of tightly coiled hair in those of African descent is the first step in the journey of diagnosing and treating hair loss in partnership with the patient.  

Setting the goal is a crucial step toward patient compliance. It may be going out in public without a wig or weave and feeling confident, providing more coverage so affected areas do not show as much, improving scalp tenderness, and/or preventing further progression of the condition. These are all reasonable outcomes and each goal is uniquely tailored to each patient.  

Familiarize yourself with various hair types, hairstyles, and preferred medication vehicles by attending continuing medical education lectures on alopecia in patients with SOC and on nuances to diagnosis and treatment, reading textbooks focusing on SOC, or seeking out mentorship from a dermatologist who is a hair expert in the types of alopecia most commonly affecting patients with SOC.  

What resources do you recommend to patients for more information 

For patients with scarring alopecia, the Cicatricial Alopecia Research Foundation (http://www.carfintl.org/) is a great resource for medical information and support groups. Also, the Skin of Color Society has dermatology patient education information (http://skinofcolorsociety.org/).  

For patients who are extremely distressed by hair loss, I encourage them to see a mental health professional. The mental health impact of alopecia, despite the extent of disease, is likely underestimated. Patients sometimes need our permission to seek help, especially in many SOC communities where even seeking mental health care often is frowned upon.

Practice Gap

Onychocryptosis, or ingrown toenail, is a highly prevalent nail condition characterized by penetration of the periungual skin by the nail plate (Figure, A). Patients may report pain either while at rest or walking, which may be debilitating in severe cases and may adversely affect daily living. Treatment may be approached using conservative or surgical therapies. Conservative methods are noninvasive and appropriate for mild cases but require excellent compliance. Although nail trimming is the simplest method, it may necessitate cutting soft tissue, particularly when the nail is anchored deep within the periungual skin. Another conservative method is taping, which aims to separate the nail fold from the offending nail edge by using an adhesive. In common practice, the adhesive often detaches within a few hours, which is further exacerbated by moisture from sweating or bathing.¹ Therefore, for effective treatment of onychocryptosis, the tape typically must be reapplied multiple times per day, limiting compliance.

Tools

We propose using kinesiology tape to treat onychocryptosis. Kinesiology tape is a highly elastic adhesive that was originally employed by athletes to relieve pain while supporting muscles, tendons, and ligaments during strenuous activity. We hypothesized that its stronger adherent properties and greater elasticity would be advantageous for treatment of onychocryptosis compared to standard tape.

The Technique

A strip of tape is cut to approximately 10 to 15 mm×5 cm and is applied once daily to the lateral nail fold, pulling it away from the nail plate in oblique and proximal directions and then wrapping it around the plantar surface dorsally (Figure, B). Kinesiology tape properties allow for less frequent application and greater tension to be applied to the nail fold while reducing the risk for vasoconstriction, as the tape does not need to be fully wrapped around the digit for reliable adherence.

Practice Implications

Kinesiology tape adheres more firmly than other tapes and requires less frequent applications. Use of kinesiology tape for onychocryptosis therapy often is effective and may negate the need for more invasive procedures and improve quality of life during and after treatment.

What does your patient need to know at the first visit?

Patient education is important initially. There are several causes for nail dystrophy. Oftentimes, when patients present, they believe that they have onychomycosis. Therefore, it is important to counsel individuals with potential nail psoriasis (Figure) and to discuss the differential diagnosis of the condition.

The presence of psoriasis on other areas of the body and the absence of fungal infection on the soles of the feet and in between the toes increases the likelihood of nail psoriasis. The most accurate test to perform is a nail clipping with subsequent periodic acid–Schiff stain. It is important to remember, however, that nail psoriasis and fungal infection of the nail can coexist.

Once the diagnosis of nail psoriasis is established, it is important to review gentle care of the nails. A thorough discussion of therapeutic options is helpful. Patients also should be advised that the presence of nail psoriasis can increase the likelihood of the development of
psoriatic arthritis.

What are your go-to treatments?

Prior to the development of biologic therapies, topical treatments were the mainstay of treatment. Topical corticosteroid preparations can be used around and under the nail. Other therapeutic options include topical calcipotriene and topical retinoids.

Intralesional injection is another therapeutic option. Injection into the nail bed is useful for the treatment of nail bed symptoms of nail psoriasis such as onycholysis. Injection into the proximal nail fold can ameliorate signs of nail matrix psoriasis such as nail pitting. Although injection can be effective, it also can be painful; therefore, many patients do not opt to have this therapy performed.

Systemic therapy has been shown to be highly effective in improving nail psoriasis. There has been a good amount of data from studies specifically done in nail psoriasis and nail data that have been taken from larger phase 3 trials (Elewski et al; van de Kerkhof et al). Therefore, several of the biologics on the market as well apremilast are good options for the treatment of nail psoriasis. When using a systemic agent, it is important to carefully review the benefits and risks of each therapy with patients. Because the nail grows slowly, improvement can be gradual and take several months to peak.

How do you keep patients compliant with treatment?

Because nail psoriasis causes distress among patients, it generally is not too hard for them to be compliant. Of course, it is important to have regular follow-up to monitor progress and to reinforce the importance of continued therapy. At the end of the day, however, treatment success is the best asset to encourage continued compliance.

What does your patient need to know preoperatively?

Patients should be educated on all aspects of the procedure as well as the expected postoperative course of healing. Manage patient expectations in advance to minimize any surprises for everyone involved. Swelling and bruising are not uncommon in the immediate postoperative phase, and for surgery near the eyes, both may be worse, making it prudent for patients to schedule any procedures after big events or vacations.

The sutured wound initially can appear lumpy, bumpy, and pink, and it may take potentially 3 to 6 months, or even longer, for the scar to fully mature depending on the type of repair performed. Sutured wounds require activity restrictions, which is especially important for young active patients as well as patients who may have labor-intensive occupations. I often recommend 1 to 2 weeks before resuming most forms of strenuous exercise and/or physical labor. Skin grafts may require even longer limitations. Although the overall risk for infection is low (approximately 1%), patients should be instructed to monitor for purulent drainage, fever, and worsening pain and redness, and to inform the dermatologist immediately of any concerning symptoms.

What is your go-to approach for wound closure?

My motto is: Simplest is often best. For the patient who prioritizes returning to full activity as soon as possible, the wound may be able to heal by secondary intention in select anatomic locations, and this approach can often yield excellent cosmetic results. If wound closure with sutures is indicated, then I use the following treatment algorithm:

1. Primary closure is used if I can close a wound in a linear fashion without distorting free margins, especially if I can hide the lines within cosmetic subunit junctions and/or relaxed skin tension lines.
2. Local flap is used for defects when repair in a linear fashion is not always ideal for various reasons. Recruit local skin with various flap options for the best color and texture match. This approach may be more involved but often provides the best long-term cosmetic outcome; however, it usually results in a longer recovery time and may even require staged procedures.
3. Graft usually is our last preferred option because it may appear as a sewn-in patch; however, in certain anatomic locations and in the right patient, skin grafts also can yield acceptable cosmetic results.

I give trainees the following surgical technique pearls:  

• Use buried vertical mattress sutures to achieve eversion of wound edges with deep sutures
• Dermal pulley as well as epidermal pulley sutures can offset tension wonderfully, especially in high-tension areas such as the back and scalp
• Placement of a running subcuticular suture in place of epidermal stitches on the trunk and extremities can prevent track marks

How do you keep patients compliant with wound care instructions?

Two keys to high patient compliance with wound care are making instructions as simple as possible and providing detailed written instructions. We instruct patients to keep the pressure dressing in place for 48 hours. Once removed, we recommend patients clean the wound with regular soap and water daily, followed by application of petrolatum ointment. For hard-to-reach areas or on non-hair-bearing skin, my surgical assistants apply adhesive strips over the sutures, eliminating the need for daily wound care. For full-thickness skin grafts, we commonly place a bolster pressure dressing that stays in place until the patient returns to our clinic for a postoperative visit. We provide every patient with detailed written instructions as a patient handout that is specific to the type of wound closure performed.

What do you do if the patient refuses your recommendation for wound closure?

It is important to explain all wound closure options to the patient and the risks and benefits of each. I always show patients the proposed plan using a mirror and/or textbook images so that they can better understand the process. In rare cases when the patient refuses the preferred method of closure, we ensure that he/she understands the advantages and disadvantages of the proposed procedure and why the recommendation was made. If the patient still refuses, we document our lengthy discussion in the medical record. For patients who refuse our recommended plan of sutures and opt to heal by secondary intention, we will see these patients almost weekly to ensure appropriate healing as well as provide further recommendations such as a delayed repair if there is any evidence of functional impairment and/or notable cosmetic implications. A patient completely refusing a planned repair is rare.

More commonly, patients request a "simpler" repair, even if the cosmetic outcome may be suboptimal. For example, some elderly patients with large nasal defects do not want to undergo a staged flap, even though it would give a superior cosmetic result. Instead, we do the best we can with a skin graft or single-stage flap.

What resources do you provide to patients for wound care instructions?

We recommend that physicians prepare comprehensive handouts on wound care instructions that address both short-term and long-term expectations, provide instructions regarding follow-up, and encourage good sun protection behaviors. Some physicians post videos demonstrating proper wound care on their websites, which may be another useful tool.

What does your patient need to know preoperatively?

Patients should be educated on all aspects of the procedure as well as the expected postoperative course of healing. Manage patient expectations in advance to minimize any surprises for everyone involved. Swelling and bruising are not uncommon in the immediate postoperative phase, and for surgery near the eyes, both may be worse, making it prudent for patients to schedule any procedures after big events or vacations.

The sutured wound initially can appear lumpy, bumpy, and pink, and it may take potentially 3 to 6 months, or even longer, for the scar to fully mature depending on the type of repair performed. Sutured wounds require activity restrictions, which is especially important for young active patients as well as patients who may have labor-intensive occupations. I often recommend 1 to 2 weeks before resuming most forms of strenuous exercise and/or physical labor. Skin grafts may require even longer limitations. Although the overall risk for infection is low (approximately 1%), patients should be instructed to monitor for purulent drainage, fever, and worsening pain and redness, and to inform the dermatologist immediately of any concerning symptoms.

What is your go-to approach for wound closure?

My motto is: Simplest is often best. For the patient who prioritizes returning to full activity as soon as possible, the wound may be able to heal by secondary intention in select anatomic locations, and this approach can often yield excellent cosmetic results. If wound closure with sutures is indicated, then I use the following treatment algorithm:

1. Primary closure is used if I can close a wound in a linear fashion without distorting free margins, especially if I can hide the lines within cosmetic subunit junctions and/or relaxed skin tension lines.
2. Local flap is used for defects when repair in a linear fashion is not always ideal for various reasons. Recruit local skin with various flap options for the best color and texture match. This approach may be more involved but often provides the best long-term cosmetic outcome; however, it usually results in a longer recovery time and may even require staged procedures.
3. Graft usually is our last preferred option because it may appear as a sewn-in patch; however, in certain anatomic locations and in the right patient, skin grafts also can yield acceptable cosmetic results.

I give trainees the following surgical technique pearls:  

• Use buried vertical mattress sutures to achieve eversion of wound edges with deep sutures
• Dermal pulley as well as epidermal pulley sutures can offset tension wonderfully, especially in high-tension areas such as the back and scalp
• Placement of a running subcuticular suture in place of epidermal stitches on the trunk and extremities can prevent track marks

How do you keep patients compliant with wound care instructions?

Two keys to high patient compliance with wound care are making instructions as simple as possible and providing detailed written instructions. We instruct patients to keep the pressure dressing in place for 48 hours. Once removed, we recommend patients clean the wound with regular soap and water daily, followed by application of petrolatum ointment. For hard-to-reach areas or on non-hair-bearing skin, my surgical assistants apply adhesive strips over the sutures, eliminating the need for daily wound care. For full-thickness skin grafts, we commonly place a bolster pressure dressing that stays in place until the patient returns to our clinic for a postoperative visit. We provide every patient with detailed written instructions as a patient handout that is specific to the type of wound closure performed.

What do you do if the patient refuses your recommendation for wound closure?

It is important to explain all wound closure options to the patient and the risks and benefits of each. I always show patients the proposed plan using a mirror and/or textbook images so that they can better understand the process. In rare cases when the patient refuses the preferred method of closure, we ensure that he/she understands the advantages and disadvantages of the proposed procedure and why the recommendation was made.

Practice Gap

Mohs micrographic surgery (MMS) is a highly curative tissue-sparing skin cancer treatment¹ and is a required component of dermatology residency training. According to the Accreditation Council for Graduate Medical Education, residents must have exposure “either through direct observation or as an assistant in Mohs micrographic surgery, and reconstruction of these defects, to include flaps and grafts.”² The MMS technique allows for complete circumferential peripheral and deep margin assessment of excised specimens; however, the conformation of a 3-dimensional gross tissue specimen into a 2-dimensional specimen as represented on a microscope slide is challenging to conceptualize.

Behavioral science research has shown that analogies and metaphors help integrate topics into a memorable format and produce deeper comprehension.³ As such, analogies can aid in the visualization of these complex spatial concepts. The MMS tissue-processing technique has been compared to flattening a pie pan.⁴ More recently, a peanut butter cup analogy was described as a visualization tool for explaining the various steps of MMS to patients.⁵ Although these analogies may help elucidate certain aspects of the MMS technique, none adequately account for the multilayered anatomy of the skin.

The Technique

To address this need, we developed the cantaloupe analogy, which provides visual representation of the 3 basic skin layers: (1) the rind represents the epidermis; (2) the flesh represents the dermis, and (3) the seed cavity represents the subcutaneous layer (Figures 1 and 2).

In MMS tissue processing, the peripheral margin of the ovoid excised skin specimen is pressed down into the same plane as the deepest layer through a process called relaxation.⁴ The cantaloupe represents the dome shape of the relaxed tissue, which is then serially sectioned in horizontal layers from deep to superficial (Figure 2). The first slice represents the deepest subcutaneous layer and most peripheral dermal and epidermal layers of the specimen (Figure 3). Using the cantaloupe analogy, subsequent stages (if warranted) would be guided by the location of the residual skin cancer. If the skin cancer is in the epidermis (rind) or dermis (flesh), then a skin specimen from the perimeter of the defect would be indicated. Residual skin cancer extending into the subcutaneous layer (seed cavity) would require a deeper resection.

Practice Implications

The cantaloupe provides a simple analogy to conceptualize the transition from the multilayered 3-dimensional skin tissue specimen to the 2-dimensional histologic slide specimen. Use of this cantaloupe analogy will aid dermatology residents and others interested in gaining a clearer understanding of MMS.

What do patients need to know initially about psoriasis treatment?

It is important to set expectations with the patient based on the treatment selected, not only for patient satisfaction but to forge an enduring bond with the patient so he/she will trust you to guide the treatment plan if the first therapy does not work as well as anticipated. Because psoriasis is a longitudinal disease process, the patient-physician relationship should be, too. Certainly, these principles generally apply among all patient groups and demographics; however, one may take into account a few special circumstances when dealing with psoriasis. In a pediatric patient, I may try to see if topical therapy including calcipotriene can adequately treat the skin disease before pursuing systemic treatment. The rationale is 2-fold: (1) this patient would be committed to an extended period on immunomodulatory therapy if he/she truly requires it, and (2) some of the forms of psoriasis in children, such as guttate psoriasis, may be self-limited, so it is reasonable to see if it will persist before forging ahead with a long-term systemic medication. In patients with a recent history of cancer, I would likely choose an oral medication such as apremilast before a biologic; even though there are no real data to suggest biologics are associated with higher rates of solid-organ malignancy, most practitioners would err on the side of being more conservative. For patients with human immunodeficiency virus, the tendency is to use the agents with more data (eg, tumor necrosis factor α inhibitors) due to safety concerns with an immunomodulatory medication.

What are your go-to treatments?

I tend to be as aggressive as the patient wants to be with therapy. I regularly see patients in whom multiple systemic treatments have failed and a more creative regimen is needed, such as combining a biologic medication with an oral antipsoriatic treatment (eg, apremilast, acitretin). However, I do have patients with moderate to severe psoriasis who have not seen a dermatologist before. I do not find it necessary to have topical treatments fail before starting a biologic; after all, the sequelae of long-term topical steroid use are notable.

With the newer biologics on the market, such as the IL-17 and IL-23 inhibitors, the sky's the limit for psoriasis area and severity index clearance, but the true benefit is that these medications are much more targeted toward the pathogenesis of psoriasis. Unfortunately, we have to be mindful of insurance and formulary restrictions, but when faced with choosing a broad-acting immunomodulatory agent or a more specific/targeted immunomodulatory agent for an inflammatory disease, most dermatologists would choose the more targeted medication. The data support that the newer agents have better psoriasis area and severity index responses and a much greater proportion of clearance, but there is something to be said about biologics such as etanercept, adalimumab, and ustekinumab, which have been on the market for much longer and have shown durable response with a longer track record of safety and efficacy. Recent head-to-head comparisons can help guide treatment. For instance, patients who achieved suboptimal clearance on ustekinumab can safely and reasonably be switched to guselkumab based on the findings of the NAVIGATE study, which looked at this exact situation. More of these studies looking at specific prior treatment failures and improvement upon switching to a newer agent are needed to underscore the efficacy of these drugs and also to help argue for their placement on insurance formularies.

For a new patient with psoriasis, I will screen for psoriatic arthritis, look at involvement (eg, body surface area, individual plaque severity/thickness, locations such as scalp and extremities), and assess patient attitudes toward different treatments. Two patients with the exact same clinical appearance might have completely different strategies, one wanting to be as aggressive as possible to get rid of the psoriasis and the other not believing in systemic treatments and wanting to be as "natural" as possible.

For patients with only cutaneous involvement, the dosing frequency and efficacy of the newer IL-17 and IL-23 classes of medications are hard to beat. If a patient has notable psoriatic arthritis, I still tend to reach for a tumor necrosis factor α inhibitor first. For patients with limited involvement, especially those with scalp and/or palmoplantar psoriasis, I have found that apremilast works quite well. Apremilast, in general, would be a good first-step medication for patients wary of systemic therapy, and with its relatively benign side-effect profile, it has almost completely supplanted methotrexate in my practice. We also have a few newer topical medicines such as a calcipotriene 0.005%-betamethasone dipropionate 0.064% foam and a betamethasone dipropionate spray 0.05% that have proven useful, with more products in the pipeline.

How do you keep patients compliant with treatment?

Setting expectations is most important, and letting patients know what to expect from their first visit really helps to keep them satisfied with the plan and progress. Giving the patient a say in guiding the treatment and perhaps coming up with a rough treatment plan with a defined timeline also helps, such as starting with a topical regimen but moving on to an oral medicine if the topical does not work within 2 to 3 months, and then a biologic if oral therapy does not work well within 3 to 6 months. It is important not to push the patient to pursue a more aggressive therapy unless he/she wants to, otherwise the patient might not be compliant or may stop altogether.

What do you do if they refuse treatment?

If the patient is in your office, clearly he/she does want some help. Try to figure out what is at the root of the treatment refusal. Is the patient refusing topical steroids because he/she is afraid of them? Is the patient unable to stomach having to inject himself/herself? Finding the basis of their reticence may take more time, but we usually can find a mutually agreeable plan of action. Even if the first step is to watch and wait, you want the patient leaving your office knowing that if things do not progress as expected or get worse, they can have faith in you to come back and get more help.

What resources do you recommend to patients for more information?

The National Psoriasis Foundation is a great resource for patients. They have numerous outreach programs and a wealth of patient information. Also, the American Academy of Dermatology is a good resource, not just for patients but for providers; for example, the academy offers appeals letters that can be sent to insurance companies to try to advocate for a specific medication for patients.

What are your go-to treatments?

I tend to be as aggressive as the patient wants to be with therapy. I regularly see patients in whom multiple systemic treatments have failed and a more creative regimen is needed, such as combining a biologic medication with an oral antipsoriatic treatment (eg, apremilast, acitretin). However, I do have patients with moderate to severe psoriasis who have not seen a dermatologist before. I do not find it necessary to have topical treatments fail before starting a biologic; after all, the sequelae of long-term topical steroid use are notable.

With the newer biologics on the market, such as the IL-17 and IL-23 inhibitors, the sky's the limit for psoriasis area and severity index clearance, but the true benefit is that these medications are much more targeted toward the pathogenesis of psoriasis. Unfortunately, we have to be mindful of insurance and formulary restrictions, but when faced with choosing a broad-acting immunomodulatory agent or a more specific/targeted immunomodulatory agent for an inflammatory disease, most dermatologists would choose the more targeted medication. The data support that the newer agents have better psoriasis area and severity index responses and a much greater proportion of clearance, but there is something to be said about biologics such as etanercept, adalimumab, and ustekinumab, which have been on the market for much longer and have shown durable response with a longer track record of safety and efficacy. Recent head-to-head comparisons can help guide treatment. For instance, patients who achieved suboptimal clearance on ustekinumab can safely and reasonably be switched to guselkumab based on the findings of the NAVIGATE study, which looked at this exact situation. More of these studies looking at specific prior treatment failures and improvement upon switching to a newer agent are needed to underscore the efficacy of these drugs and also to help argue for their placement on insurance formularies.

For a new patient with psoriasis, I will screen for psoriatic arthritis, look at involvement (eg, body surface area, individual plaque severity/thickness, locations such as scalp and extremities), and assess patient attitudes toward different treatments. Two patients with the exact same clinical appearance might have completely different strategies, one wanting to be as aggressive as possible to get rid of the psoriasis and the other not believing in systemic treatments and wanting to be as "natural" as possible.

For patients with only cutaneous involvement, the dosing frequency and efficacy of the newer IL-17 and IL-23 classes of medications are hard to beat. If a patient has notable psoriatic arthritis, I still tend to reach for a tumor necrosis factor α inhibitor first. For patients with limited involvement, especially those with scalp and/or palmoplantar psoriasis, I have found that apremilast works quite well. Apremilast, in general, would be a good first-step medication for patients wary of systemic therapy, and with its relatively benign side-effect profile, it has almost completely supplanted methotrexate in my practice. We also have a few newer topical medicines such as a calcipotriene 0.005%-betamethasone dipropionate 0.064% foam and a betamethasone dipropionate spray 0.05% that have proven useful, with more products in the pipeline.

How do you keep patients compliant with treatment?

Setting expectations is most important, and letting patients know what to expect from their first visit really helps to keep them satisfied with the plan and progress. Giving the patient a say in guiding the treatment and perhaps coming up with a rough treatment plan with a defined timeline also helps, such as starting with a topical regimen but moving on to an oral medicine if the topical does not work within 2 to 3 months, and then a biologic if oral therapy does not work well within 3 to 6 months. It is important not to push the patient to pursue a more aggressive therapy unless he/she wants to, otherwise the patient might not be compliant or may stop altogether.

What do you do if they refuse treatment?

If the patient is in your office, clearly he/she does want some help. Try to figure out what is at the root of the treatment refusal. Is the patient refusing topical steroids because he/she is afraid of them? Is the patient unable to stomach having to inject himself/herself? Finding the basis of their reticence may take more time, but we usually can find a mutually agreeable plan of action. Even if the first step is to watch and wait, you want the patient leaving your office knowing that if things do not progress as expected or get worse, they can have faith in you to come back and get more help.

What resources do you recommend to patients for more information?

The National Psoriasis Foundation is a great resource for patients. They have numerous outreach programs and a wealth of patient information. Also, the American Academy of Dermatology is a good resource, not just for patients but for providers; for example, the academy offers appeals letters that can be sent to insurance companies to try to advocate for a specific medication for patients.

What does your patient need to know at the first visit?

Risk factors for onychomycosis include prior trauma, history of tinea pedis, sports activities, frequenting gyms and pools, hyperhidrosis, advancing age, diabetes mellitus, immunosuppression, smoking, and family history of onychomycosis. Toenails are involved more frequently than fingernails, and typical physical examination findings are distal and lateral nail plate onycholysis with subungual hyperkeratosis. In more severe cases, there may be nail plate thickening, crumbling, yellowing, and involvement of the nail matrix.

Because other nail conditions may resemble onychomycosis, it is imperative to confirm the diagnosis using histopathology, direct microscopy, fungal culture, and/or polymerase chain reaction on nail plate clippings or subungual debris. 

What are your go-to treatments? What are the side effects?

After laboratory confirmation, assess the patient for the severity of the infection based on the surface area of nail plate affected, nail plate thickness, involvement of the nail matrix, and number of nails affected. United States Food and Drug Administration-approved oral and topical antifungals are used first line for the treatment of onychomycosis. Devices such as lasers are approved by the US Food and Drug Administration for temporary cosmetic improvement in the appearance of the nail without eradicating the fungus.

Oral antifungals such as terbinafine, itraconazole, and fluconazole (off label) are indicated for patients with severe disease. Patients with mild to moderate disease may benefit from oral or topical antifungals such as efinaconazole, tavaborole, or ciclopirox.

I recommend terbinafine to many of my patients due to its high complete and mycological cure rates, short list of drug-drug interactions, and low incidence of side effects. Adverse reactions are uncommon, with the most common being gastrointestinal upset. While liver injury has been reported, it is exceedingly rare. Itraconazole has many important drug interactions and is contraindicated in patients with congestive heart failure. With topical antifungals, side effects are uncommon, but dermatitis, ingrown nails, and vesicles may occur.

How do you keep patients compliant with treatment?

Patients on a 3-month course of daily oral terbinafine or itraconazole for toenail onychomycosis are typically highly compliant. Compliance for patients on oral fluconazole (off label) is generally more challenging because it is dosed weekly until the nail grows out (1-1.5 years for toenails). To circumvent missed fluconazole doses, I recommend that the patient schedule quarterly visits with me and also to set a cell phone alarm as a weekly reminder to take the medication.

Because topical medications are prescribed for the toenails for a year-long course (with avoidance of nail polish during this period), I prescribe topical antifungals only to highly motivated patients. In addition, because topical antifungals are retained in the nail plate for at least several days after a month-long application, I tell my patients that if they have a big event to attend that they can take a vacation from the topical antifungal, get a pedicure, and then resume treatment after the event. 

What do you do if they refuse treatment?

In 2018, we have many options to treat onychomycosis effectively, and therapy is individualized based on the patient's severity of disease, infecting organism(s), comorbidities, concomitant medications, and preferences. If the patient's fungal nail infection is asymptomatic and not aesthetically bothersome, he/she may opt for observation rather than treatment. If the decision is observation, I recommend use of a topical antifungal on the feet and web spaces to prevent worsening of onychomycosis.

What is the recent research behind 5-fluorouracil cream 5% combined with calcipotriol ointment 0.005% for actinic keratoses?

Cunningham et al published a randomized double-blind study in which 131 patients with actinic keratoses (AKs) were assigned to either 5-fluorouracil (5-FU) cream 5% combined with calcipotriol (calcipotriene) ointment 0.005% twice daily to the face, scalp, and arms for 4 days, or 5-FU 5% combined with petrolatum applied in the same fashion. There was an 87.8% versus 26.3% mean reduction in the number of AKs and less severe pain, crusting, and ulceration in the study cohort compared to the 5-FU plus petrolatum group.

The same study also investigated immune parameters in these patients and found that the study group preferentially displayed activated thymic stromal lymphopoietin and a CD4 T cell-mediated reaction, among other effects. In prior studies, thymic stromal lymphopoietin has been shown to be upregulated in barrier-defective skin, displays antitumor activity, and is enhanced by topical calcipotriol application based on its original indication for psoriasis.

How do these study results impact patient care?

In a perfect world, every patient could tolerate and afford chemopreventative measures such as 5-FU cream, apply it diffusely to sun-exposed skin, and experience no severe irritant reactions and/or social pariah status. We all know that this product is effective, and we all overprepare patients to use it, knowing that they will call our offices panicked and fearful that they are allergic to or are becoming infected by this cream.

Although further study clearly is needed to determine the optimal application amount, duration of use, and vehicle mix, this new compound utilizing 2 topicals that are familiar to us--5-FU cream approved for AKs and early squamous cell skin cancers and calcipotriol ointment (though available only in cream in the United States currently) for psoriasis--is an encouraging step. Home therapy for AKs and possibly early nonmelanoma skin cancers that is more tolerable, of shorter duration, and in turn more effective than the current options would lessen the burden of treating these lesions surgically or rescheduling 5-FU patients often for irritation reaction education.

How do patients respond to this regimen?

In my own anecdotal experience, this regimen has been well received by patients and often is covered by most insurances when written as 2 separate prescriptions (both in cream vehicle).  They still report some irritation, but I prefer to utilize it segmentally instead of treating all sun-exposed areas at once (ie, treat one side of the face/scalp twice daily for 4 days, then the other, or even divide it into smaller segments once the prior segment has healed). This combination, in addition to, for example, adding nicotinamide 500 mg twice daily to a patient's skin cancer chemopreventative sequence, is in my opinion a novel but safe, effective, and well-tolerated field therapy recommendation.

Practice Gap

For first-year dermatology residents, dermatologic surgeries can present many challenges. Although approximation of wound edges following excision may be intuitive for the experienced surgeon, an early trainee may need some guidance. Infusion of anesthetics can distort the normal skin field or it may be difficult for the patient to remain in the same position for the required period of time; for example, an elderly patient who requires an excision on the posterior aspect of the neck may be unable to assume the same position for the full duration of the procedure. We offer a simple and effective technique for early-learning dermatology residents to improve surgical closures.

The Technique

We propose drawing straight lines using a sterile marking pen perpendicular to the fusiform plane laid out for any simple, intermediate, or complex linear closure (Figure 1). These lines can then be used as scaffolding for the surgical closure (Figure 2). We recommend drawing the lines at the time of initial planning when the site of excision is in the normal anatomic position.

Practice Implications

By creating a sketch with perpendicular lines, approximation of skin edges and surgical closures may become easier for the learning resident. Patients also can rest more comfortably during the procedure, and the overall cosmesis, healing, and outcome of the procedure may improve. The addition of a sterile marking pen to the surgical tray may aide in highlighting faded pen markings for easier visualization after cleansing of the surgical site.

Patients also can rest more comfortably during the procedure, and the overall cosmesis, healing, and outcome of the procedure may improve. The addition of a sterile marking pen to the surgical tray may aide in highlighting faded pen markings for easier visualization after cleansing of the surgical site.

Practice Gap

For first-year dermatology residents, dermatologic surgeries can present many challenges. Although approximation of wound edges following excision may be intuitive for the experienced surgeon, an early trainee may need some guidance. Infusion of anesthetics can distort the normal skin field or it may be difficult for the patient to remain in the same position for the required period of time; for example, an elderly patient who requires an excision on the posterior aspect of the neck may be unable to assume the same position for the full duration of the procedure. We offer a simple and effective technique for early-learning dermatology residents to improve surgical closures.

The Technique

We propose drawing straight lines using a sterile marking pen perpendicular to the fusiform plane laid out for any simple, intermediate, or complex linear closure (Figure 1). These lines can then be used as scaffolding for the surgical closure (Figure 2). We recommend drawing the lines at the time of initial planning when the site of excision is in the normal anatomic position.
