Blood pressure changes with alemtuzumab infusion in MS
Key clinical point: This study found significant increases in blood pressure (BP) during alemtuzumab infusions in patients with multiple sclerosis (MS).
Major finding: For cycle 1, systolic BP (SBP) increased by 19.2 ± 9.4 mmHg during first infusion, with comparable percentage over the next 5 infusions (16%, 22%, 17%, 11%, and 13%), respectively. Diastolic BP (DBP) increased by 6.2 ± 3.8 mmHg with similar percentage increase as well (8.4%, 11.5%, 5.5%, 7%, and 3%). Second cycle (12 months later) showed similar increases in SBP and DBP as the first cycle. Third cycle (at variable follow-up times) showed similar trends with increased SBP and DBP. Overall, 54.8% of patients had increasing BP reading by 20% or more from baseline, while 29% had increased by at least 20 mmHg from baseline.
Study details: The data come from a retrospective study of SBP and DBP in MS patients treated with alemtuzumab at the London MS Clinic (n = 31; 64.5% females; mean age, 35.2 years).
Disclosures: No study sponsor was identified. Eslam Shosha and Christine Tomkinson reported no disclosures. Sarah Morrow and Courtney Casserly reported relationships with multiple pharmaceutical companies.

Prescribing Patterns of Onychomycosis Therapies in the United States
To the Editor:
Onychomycosis is the most common nail disorder, affecting approximately 5.5% of the world’s population.1 There are a limited number of topical and systemic therapies approved by the US Food and Drug Administration (FDA), but no consensus guidelines exist for the management of onychomycosis. Therefore, we hypothesized that prescribing patterns would vary among different groups.
We examined data from the Centers for Medicare & Medicaid Services’ Part D Prescriber Public Use Files for 2013 to 2016.2 Prescribing patterns were assessed for dermatologists, nurse practitioners, physician assistants, and podiatrists prescribing systemic (ie, terbinafine, itraconazole) or topical (ie, efinaconazole, tavaborole, ciclopirox) therapies. A cut-off of systemic therapy lasting 84 days or more (reflecting FDA-approved treatment regimens for toenail onychomycosis) was used to exclude prescriptions for other fungal conditions that require shorter treatment courses. Statistical analysis with χ2 tests identified differences among specialties’ prescribing patterns.
Overall, onychomycosis medications accounted for $85.4 million in expenditures from 2013 to 2016, with spending increasing at a rate of 21.2% annually (Table 1). The greatest single-year increase was observed from 2014 to 2015, with a 40.6% surge in overall expenditures for onychomycosis medications—increasing from $17.8 million to $25.0 million in spending. Dermatologists’ prescriptions accounted for 14.8% of all claims for onychomycosis medications and 18.3% of total expenditures during the study period, totaling $15.7 million in costs. Dermatologists’ claims increased at a rate of 7.4% annually, while expenditures increased at 15.4% annually. A greater proportion of dermatologists (96.4%) prescribed topicals for onychomycosis relative to nurse practitioners (90.2%) and podiatrists (91.3%)(P<.01)(Table 2). No significant difference was observed in the prescribing patterns of dermatologists and physician assistants (P=.99).
Per-claim spending for treating onychomycosis increased 7.4% annually for dermatologists, second only to podiatrists at 17.2% annually. Each analyzed group reported at least a 7% annual increase in the amount of topicals prescribed for onychomycosis. Following their FDA approvals in 2014, tavaborole and efinaconazole accounted for 0.9% and 2.3% of onychomycosis claims in 2016, respectively, and 15.0% and 25.1% of total Medicare expenditures on onychomycosis treatments that same year, respectively. Itraconazole also disproportionately contributed to expenditures, accounting for 1.3% of onychomycosis claims in 2016 while accounting for 9.5% of total expenditures.
The introduction of efinaconazole and tavaborole in 2014 resulted in large increases in Medicare spending for onychomycosis. Limited manufacturer competition due to patents may contribute to increased spending on these topicals in the future.3 A prior analysis demonstrated that podiatrists prescribe topicals more often than other clinicians,4 but after adjusting for the number of dermatologists managing onychomycosis, we found that a greater proportion of dermatologists (96.4%) are prescribing topicals for onychomycosis than other clinicians. This includes these newly approved, high-cost topicals, thus disproportionately contributing to the cost burden of onychomycosis treatment.
Ciclopirox is the most commonly prescribed therapy for onychomycosis across all groups, prescribed by more than 88% of prescribers in all studied specialties. Although ciclopirox is one of the least expensive treatment options available for onychomycosis, it has the lowest relative cure rate.5 Onychomycosis management requires understanding of drug efficacy and disease severity.6 Inappropriate treatment selection may result in prolonged treatment courses and increased costs. Consensus guidelines for onychomycosis therapies across specialties may yield more cost-effective treatment for this common nail condition.

Practice Points
- Dermatologists should consider efficacy and cost of onychomycosis therapies, as inappropriate treatment selection results in longer treatment courses and increased costs.
- Creation of consensus guidelines for the management of onychomycosis may decrease the costs of treating this difficult-to-manage disease.
Natalizumab superior to fingolimod for active relapsing-remitting MS
Key clinical point: The proportion of patients with active relapsing-remitting multiple sclerosis (MS) reaching “no evidence of disease activity” (NEDA) was greater with natalizumab (NTZ) vs. fingolimod (FTY) after a year of treatment.
Major finding: At 12 months, 47.8% of NTZ-treated patients reached NEDA vs. 30.4% of FTY-treated patients. The risk of relapse was lower with NTZ vs. FTY after 6 months of treatment (annualized relapse rate, 0.02 vs. 0.09; P = .05). MRI outcomes revealed a higher NTZ effectiveness regarding the number of new T2 (0.44 vs. 1.14; P = .03) and gadolinium-enhancing (0.03 vs. 0.48; P = .03) lesions.
Study details: BEST-MS was a multicentric, prospective study with a 12-month follow-up period that compared the efficacy of NTZ and FTY in active relapsing-remitting MS. A total of 223 patients were included (109 patients were treated with NTZ and 114 with FTY).
Disclosures: The study has received funding from FP7 Health Innovation-1 in 2012. Pierre Labauge received grants from Biogen and Novartis. Kevin Bigaut received grant travel by Biogen Idec and Sanofi-Genzyme. No other disclosures were reported.

PPMS: Sustained benefit of ocrelizumab treatment on disease progression
Key clinical point: Earlier and continuous ocrelizumab treatment provided sustained benefits on measures of disease progression in patients with primary progressive multiple sclerosis (PPMS).
Major finding: Over a period of 6.5 study years, the proportion of patients with progression on disability measures at 24 weeks was lower in those who started ocrelizumab early vs. those who started with placebo: Expanded Disability Status Scale Score (51.7% vs. 64.8%; P = .0018), 9-Hole Peg Test (30.6% vs. 43.1%; P = .0035), Timed 25-Foot Walk (63.2% vs. 70.7%; P = .058), and composite progression (73.2% vs. 83.3%; P = .0023). No new safety signals emerged compared with the double-blind phase of ORATORIO.
Study details: The findings are based on a long-term follow-up from the phase 3 ORATORIO extension study. 732 patients with PPMS were randomly assigned (2:1) to receive ocrelizumab or placebo every 24 weeks for at least 120 weeks. Overall, 544 participants completed the double-blind period and 527 people entered the open-label extension phase, during which they continued ocrelizumab or switched from placebo to ocrelizumab.
Disclosures: The study was funded by F Hoffmann-La Roche. The presenting author received personal fees for consulting, serving on a scientific advisory board, speaking, or other activities with AbbVie, Actelion, Alkermes, Brainstorm Cell Therapeutics, Celgene, EMD Serono, GeNeuro, GW Pharma, MedDay Pharmaceuticals, NervGen Pharma, Novartis, Otsuka, PTC Therapeutics, Roche/Genentech, and Sanofi Genzyme; and royalties for out licensed monoclonal antibodies through UTHealth from Millipore Corporation.

Dermatology Battles COVID-19 With Comfort
We are in unprecedented times. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is attacking our communities and, as with any battle, we face unexpected challenges from the global pandemic. What can dermatologists, as highly skilled health care experts, do to support the fight against coronavirus disease 2019 (COVID-19)?
In early 2020, I became involved in a fulfilling and stimulating opportunity to contribute as a US Navy reservist, having just returned from a 3-month deployment. I served in the Medical Operations Center aboard the hospital ship USNS Comfort, which was docked in New York Harbor, as liaison to surrounding New York City hospitals. I also served as sole dermatologist on the ship, caring for the dermatologic needs of our team and consulting on numerous COVID-19 inpatients.
In May 2020, upon return to Virginia from New York City, I served as senior medical officer to medically clear other Navy Reserve health care workers returning from the field hospital at the Jacob K. Javits Convention Center of New York and from serving as embedded caregivers in existing New York City hospitals. I share 2 very important observations from my work there: First, COVID-19 is devastatingly real; second, we dermatologists can be valuable team members in the fight against this disease.
It is normal for us to feel scared, confused, and helpless; as 1% of the physician population, dermatologists represent a small focused fraction of the health care force. Nevertheless, we are all well-trained medical professionals who have taken the same Hippocratic Oath as other physicians. As members of the global health care team, we can each play a role in defeating COVID-19: We can be a trusted voice of reason, set an example, implement safe and effective distancing and hygiene precautions, and assist our local overburdened medical teams.
The magnitude and severity of COVID-19 can create a mass casualty–type phenomenon, overwhelming health care systems if the disease curve is not flattened. We can help flatten that curve by lengthening the pulse duration (to use dermatology jargon): that is, slowing the abrupt impact of cases to allow health care systems to triage, treat, and discharge in a more controlled manner.
How We Can Make a Difference
Despite representing a fraction of the health care team, we see a larger percentage of the population. On the Comfort, for example, dermatology visits accounted for approximately 20% of outpatient crew visits. We have an opportunity and a voice to reach a large percentage of the population directly. Whether we are now seeing patients face-to-face or virtually, we can spread the public health message and set an example. Wearing masks and social distancing do help to slow and markedly decrease the spread of SARS-CoV-2.
When you see patients in your office, consider the following:
• Have patients wait outside the office in their car and call the receptionist upon arrival.
• Have the receptionist call back the patient when the office is ready.
• Prescreen the patient before having him/her enter the clinic.
• Do not allow handshaking.
• Require everyone to wear a mask.
• Wear gloves.
• Have ample hand sanitizer openly available for all.
• Thoroughly clean or disinfect surfaces between patients.
Recalling the Difficult Experience of a Colleague-Patient
I think back to a crew member of Comfort who presented with new-onset pruritus and erythematous papules on the arms, legs, and torso. She was an intensive care unit nurse working 13-hour days, every day, for weeks on a COVID-positive unit—double-masked, gowned, wearing eye protection, in a warmer than usual intensive care unit, managing the most critically ill patients she’s ever cared for. Outside work, her life consisted of a commute on a government-chartered bus between Comfort and a contracted hotel while eating boxed meals. For 6 hours daily, she would—unsuccessfully—attempt to sleep with raging pruritus. Treating this routine case of eczema had a domino effect, improving her quality of life and thus allowing her to provide better care for the critically ill.
Let Us All Join in the Fight
As well-educated medical experts, we have the ability and the opportunity to reach outside our comfort zone and assist our medical colleagues. As I saw in New York City, the spectrum of specialists bravely worked together to meet overwhelming demand on the health care system and care for thousands of critically ill and dying patients. Dermatologists treated extensive eczema, ulcers, and other dermatoses on caretakers; triaged patients for appropriate allocation of care; and delivered care outside their comfort zone as physician extenders on inpatient and critical care units.
We are all in this together. I encourage all dermatologists who are in an area of need to ask your health care system how you can join the fight against SARS-CoV-2. Let’s step forward to help, in recognition of the oath we took to “prevent disease whenever we can.”
We are in unprecedented times. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is attacking our communities and, as with any battle, we face unexpected challenges from the global pandemic. What can dermatologists, as highly skilled health care experts, do to support the fight against coronavirus disease 2019 (COVID-19)?
In early 2020, I became involved in a fulfilling and stimulating opportunity to contribute as a US Navy reservist, having just returned from a 3-month deployment. I served in the Medical Operations Center aboard the hospital ship USNS Comfort, which was docked in New York Harbor, as liaison to surrounding New York City hospitals. I also served as sole dermatologist on the ship, caring for the dermatologic needs of our team and consulting on numerous COVID-19 inpatients.
In May 2020, upon return to Virginia from New York City, I served as senior medical officer to medically clear other Navy Reserve health care workers returning from the field hospital at the Jacob K. Javits Convention Center of New York and from serving as embedded caregivers in existing New York City hospitals.

Skin Eruption and Gastrointestinal Symptoms as Presentation of COVID-19
In December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started an outbreak of respiratory illnesses in Wuhan, China. The respiratory disease was termed coronavirus disease 2019 (COVID-19) and rapidly spread worldwide, resulting in a pandemic classification on March 11, 2020. 1 Recently, several cutaneous manifestations of COVID-19 have been reported. Skin manifestations have been reported to be similar to other common viral infections. 2 However, there is a paucity of published clinical images of more atypical presentations.
Case Report
A 52-year-old black man presented via urgent store-and-forward teledermatology consultation from his primary care provider with a self-described “vesicular,” highly pruritic rash of both arms and legs of 1 week’s duration without involvement of the trunk, axillae, groin, face, genitalia, or any mucous membranes. He noted nausea, loss of appetite, and nonbloody diarrhea 4 days later. He denied fever, chills, dry cough, shortness of breath, or dyspnea. He had a history of hypertension and type 2 diabetes mellitus. There were no changes in medications; no outdoor activities, gardening, or yard work; no exposure to plants or metals; and no use of new personal care products.
The digital images showed zones of flesh-colored to slightly erythematous, somewhat “juicy” papules with some coalescence into ill-defined plaques. There were scattered foci of scale and hemorrhagic crust that involved both palms, forearms (Figure, A), and legs (Figure, B). There were no intact vesicles, and a herald patch was not identified. Vital signs at the time of imaging were normal, with the exception of a low-grade fever (temperature, 37.3°C). Basic laboratory testing showed only mild leukocytosis with mild neutropenia and mild aspartate aminotransaminase elevation. A skin biopsy was not performed. Pulmonary imaging and workup were not performed because of the lack of respiratory symptoms.
The teledermatology differential diagnosis included a drug eruption, autosensitization eruption, unusual contact dermatitis, viral exanthem, secondary syphilis, and papular pityriasis rosea with an unusual distribution. The absence of changes in the patient’s medication regimen and the lack of outdoor activity in late winter made a drug eruption and contact dermatitis less likely, respectively. A rapid plasma reagin test drawn after disappearance of the rash was negative. Although the morphology of this eruption displayed some features of papular pityriasis rosea, this diagnosis was considered to be less likely given the presence of palmar involvement and the absence of any truncal lesions. This variant of pityriasis rosea is more commonly encountered in younger, darker-skinned patients.
Given the presence of an unusual rash on the extremities followed shortly by gastrointestinal (GI) symptoms and coupled with a low-grade fever, a nasopharyngeal swab was obtained to test for COVID-19 using a reverse transcriptase–polymerase chain reaction test. The results were positive.
The patient was treated with triamcinolone 0.1% slush (triamcinolone cream 0.1% mixed 1:1 with tap water) to the affected skin of the extremities 3 times daily, and he experienced a reduction in pruritus. He developed new lesions on the face and eyelids (not imaged) 2 days after teledermatology consultation. The facial involvement was treated with hydrocortisone cream 1%. During the following week, the GI symptoms and skin eruption completely resolved. However, postinflammatory hyperpigmentation was observed in areas of the resolved papules and plaques. Over the course of this illness, the patient reported no respiratory symptoms.
Comment
Coronavirus disease 2019 is caused by SARS-CoV2, an enveloped, nonsegmented, positive-sense RNA virus of the coronavirus family. It is currently believed that SARS-CoV-2 uses the angiotensin-converting enzyme 2 receptor to gain entry into human cells, leading to infection primarily affecting the lower respiratory tract.3 Patients suspected of COVID-19 infection most often present with fever, dry cough, dyspnea, and fatigue, while GI symptoms such as nausea, vomiting, and diarrhea are uncommon.4 More recently, several reports describe a variety of skin findings associated with COVID-19. A current theory suggests that the virus does not directly target keratinocytes but triggers a systemic immune response, leading to a diversity of skin morphologies.5 The main types of described cutaneous findings include pseudochilblains, overtly vesicular, urticarial, maculopapular, and livedo/necrosis.6 Others have described petechial7 and papulosquamous eruptions.8 Most of these patients initially presented with typical COVID-19 symptoms and frequently represented more severe cases of the disease. Additionally, the vesicular and papulosquamous eruptions reportedly occurred on the trunk and not the limbs, as in our case.
This confirmed COVID-19–positive patient presented with an ill-defined vesicular and papulosquamous-type eruption on the arms and legs and later developed only mild GI symptoms. By sharing this case, we report yet another skin manifestation of COVID-19 and propose the possible expansion of testing for SARS-CoV-2 in patients presenting with rash and GI symptoms, which holds the potential to increase the identification of COVID-19 in the population, thereby increasing strict contact tracing and slowing the spread of this pandemic.

- Awareness of atypical presentations of COVID-19, including uncommon cutaneous manifestations, may identify more cases and help slow the expansion of this pandemic.
Toxoplasma gondii infection may protect against MS
Key clinical point: Toxoplasma gondii (T. gondii) is negatively associated with multiple sclerosis (MS), suggesting a possible protective role of the parasite in MS.
Major finding: Anti-T. gondii antibodies were detected in 38 MS patients (29.5%) and 130 healthy controls (45.4%). After adjustment, T. gondii seropositivity was significantly associated with a reduced risk of MS (adjusted odds ratio, 0.56; P = .02).
Study details: The data come from an Italian population‑based case-control study of 129 patients with MS and 287 age- and sex-matched controls.
Disclosures: This research was funded by the Department of Medical and Surgical Sciences and Advanced Technologies “G.F. Ingrassia,” University of Catania, Italy. The authors declared no conflicts of interest.

Combined Treatment of Disfiguring Facial Angiofibromas in Tuberous Sclerosis Complex With Surgical Debulking and Topical Sirolimus
Practice Gap
Tuberous sclerosis complex (TSC) is an autosomal-dominant genetic disorder resulting in loss-of-function mutations in the TSC1 and TSC2 genes. These mutations lead to constitutive activation of the mitogenic mTOR pathway and release of lymphangiogenic growth factors, causing the formation of hamartomatous tumors throughout multiple organ systems.1 Facial angiofibromas (FAs) are a common cutaneous manifestation of TSC, affecting up to 80% of patients worldwide.2 Aesthetic disfigurement, vision obstruction, and breathing impairment often are associated with FAs. They frequently arise in children with TSC and impose a psychosocial burden that can affect the patient’s overall quality of life.
Cutaneous stigmata of TSC pose a significant therapeutic challenge. Topical sirolimus has become a first-line treatment of FAs by inhibiting the mitogenic mTOR pathway1; however, thicker, more extensive lesions are less responsive to topical therapy. The entire dermis is involved in TSC, and topical sirolimus alone often is ineffective for large fibrous FAs.3 Likewise, oral mTOR inhibition has shown only 25% to 50% improvement in FAs and has potential side effects that can limit patients’ tolerance and compliance.4
The Technique
A 46-year-old man with TSC was referred to dermatology for treatment of numerous facial papules and plaques that had been present since childhood and were consistent with FAs (Figure 1A). The lesions were tender, impaired the patient’s breathing, and caused emotional distress. Dermabrasion was attempted 20 years prior with minimal improvement and subsequent progression of the FAs. Other stigmata of TSC were present, including cutaneous hypopigmented macules and shagreen patches as well as seizures and renal angiomyolipomas. Due to multiorgan involvement, the patient was started on once-daily oral everolimus 2.5 mg; however, the FAs were progressive despite the systemic mTOR inhibition. Furthermore, it was presumed that topical sirolimus monotherapy would be ineffective due to thickness and extent of FAs; therefore, we proposed a novel treatment approach combining initial surgical debulking with subsequent longitudinal use of topical sirolimus to reduce the risk of recurrence.
Local anesthesia with lidocaine 1% and epinephrine 1:100,000 was administered. Larger FAs were removed at the base with a sterile surgical blade. Nasal recontouring subsequently was performed using a combination of shave biopsy and curettage. Extensive electrocautery was performed for hemostasis and destruction of residual FAs. Figure 1B shows the immediate postoperative result.
One month postoperatively, the patient stopped the oral everolimus at his oncologist’s recommendation due to abdominal pain and peripheral edema. Once the abraded skin showed evidence of wound healing, the patient was instructed to initiate sirolimus ointment 1% twice daily to reduce the risk of recurrence.1,5,6 At 8-week follow-up, the patient was noted to have cosmetic improvement and resolution of breathing impairment (Figure 2A). He continued to show excellent cosmetic results at 1-year follow-up using topical sirolimus monotherapy (Figure 2B).
Practical Implications
Surgical debulking combined with longitudinal use of sirolimus ointment 1% can achieve an optimal therapeutic response for disfiguring phymatous presentation of FAs in the setting of TSC. We believe it is an effective approach for thick disfiguring FAs that are unlikely to respond to mTOR inhibition alone.

Doctor in a Bottle: Examining the Increase in Essential Oil Use
What Are Essential Oils?
Essential oils are aromatic volatile oils produced by medicinal plants that give them their distinct flavors and aromas. They are extracted using a variety of different techniques, such as microwave-assisted extraction, headspace extraction, and the most commonly employed hydrodistillation.1 Different parts of the plant are used for the specific oils; the shoots and leaves of Origanum vulgare are used for oregano oil, whereas the skins of Citrus limonum are used for lemon oil.2 Historically, essential oils have been used for cooking, food preservation, perfume, and medicine.3,4
Historical Uses for Essential Oils
Essential oils and their intact medicinal plants were among the first medicines widely available to the ancient world. The Ancient Greeks used topical and oral oregano as a cure-all for ailments including wounds, sore muscles, and diarrhea. Because of its use as a cure-all medicine, it remains a popular folk remedy in parts of Europe today.3 Lavender also has a long history of being a cure-all plant and oil. Some of the many claims behind this flower include treatment of burns, insect bites, parasites, muscle spasms, nausea, and anxiety/depression.5 With an extensive list of historical uses, many essential oils are being researched to determine if their acclaimed qualities have quantifiable properties.
Science Behind the Belief
In vitro experiments with oregano (O vulgare) have demonstrated notable antifungal and antimicrobial effects.6 Gas chromatographic analysis of the oil shows much of it is composed of phenolic monoterpenes, such as thymol and carvacrol. They exhibit strong antifungal effects with a slightly stronger effect on the dermatophyte Trichophyton rubrum over other yeast species such as Candida.7,8 The full effect of the monoterpenes on fungi is not completely understood, but early data show it has a strong affinity for the ergosterol used in the cell-wall synthesis. Other effects demonstrated in in vitro studies include the ability to block drug efflux pumps, biofilm formation, cellular communication among bacteria, and mycotoxin production.9
A double-blind, randomized trial by Akhondzadeh et al10 demonstrated lavender (Lavandula officinalis) to have a mild antidepressant quality but a noticeably more potent effect when combined with imipramine. The effects of the lavender with imipramine were stronger and provided earlier improvement than imipramine alone for treatment of mild to moderate depression. The team concluded that lavender may be an effective adjunct therapy in treating depression.10
In a study by Mori et al,11 full-thickness circular wounds were made in rats and treated with either lavender oil (L officinalis), nothing, or a control oil. With the lavender oil being at only 1% solution, the wounds treated with lavender oil demonstrated earlier closure than the other 2 groups of wounds, where no major difference was noted. On cellular analysis, it was seen that the lavender had increased the rate of granulation as well as expression of types I and III collagen. The most striking result was the large expression of transforming growth factor β seen in the lavender group compared to the others. The final thoughts on this experiment were that lavender may provide new approaches to wound care in the future.11
Potential Problems With Purity
One major concern raised about essential oils is their purity and the fidelity of their chemical composition. The specific aromatic chemicals in each essential oil are maintained for each species, but the proportions of each change even with the time of year.12 Gas chromatograph analysis of the same oil distilled with different techniques showed that the proportions of aromatic chemicals varied with technique. However, the major constituents of the oil remained present in large quantities, just at different percentages.1 Even using the same distillation technique for different time periods can greatly affect the yield and composition of the oil. Although the percentage of each aromatic compound can be affected by distillation times, the antioxidant and antimicrobial effects of the oil remain constant regardless of these variables.2 There is clearly a lack in standardization in essential oil production, which may not be an issue for its use in complementary medicine if its properties are maintained regardless.
Safety Concerns and Regulations
With essential oils being a natural cure for everyday ailments, some people are turning first to oils for every cut and bruise. The danger in these natural cures is that essential oils can cause several types of dermatitis and allergic reactions. The development of allergies to essential oils is at an even higher risk, considering people frequently put them on wounds and rashes where the skin barrier is already weakened. Many essential oils fall into the fragrance category in patch tests, negating the widely circulating blogger and online reports that essential oils cannot cause allergies.
Some of the oils, although regarded safe by the US Food and Drug Administration for consumption, can cause dermatitis from simple contact or with sun exposure.13 Members of the citrus family are notorious for the phytophotodermatitis reaction, which can leave hyperpigmented scarring after exposure of the oils to sunlight.14 Most companies that sell essential oils are aware of this reaction and include it in the warning labels.
The legal problem with selling and classifying essential oils is that the US Food and Drug Administration requires products intended for treatment to be labeled as drugs, which hinders their sales on the open market.13 It all boils down to intended use, so some companies sell the oils under a food or fragrance classification with vague instructions on how to use said oil for medicinal purposes, which leads to lack of supervision, anecdotal cures, and false health claims. One company claims in their safety guide for topical applications of their oils that “[i]f a rash occurs, this may be a sign of detoxification.”15 If essential oils had only minimal absorption topically, their safety would be less concerning, but this does not appear to be the case.
Absorption and Systemics
The effects of essential oils on the skin is one aspect of their use to be studied; another is the more systemic effects from absorption through the skin. Most essential oils used in small quantities for fragrance in over-the-counter lotions prove only to be an issue for allergens in sensitive patient groups. However, topical applications of essential oils in their pure concentrated form get absorbed into the skin faster than if used with a carrier oil, emulsion, or solvent.16 For most minor uses of essential oils, the body can detoxify absorbed chemicals the same way it does when a person eats the plants the oils came from (eg, basil essential oils leaching from the leaves into a tomato sauce). A possible danger of the oils’ systemic properties lies in the pregnant patient population who use essential oils thinking that natural is safe.
Many essential oils, such as lavender (L officinalis), exhibit hormonal mimicry with phytoestrogens and can produce emmenagogue (increasing menstrual flow) effects in women. Other oils, such as those of nutmeg (Myristica fragrans) and myrrh (Commiphora myrrha), can have abortifacient effects. These natural essential oils can lead to unintended health risks for mother and baby.17 With implications this serious, many essential oil companies put pregnancy warnings on most if not all of their products, but pregnant patients may not always note the risk.
Conclusion
Essential oils are not the newest medical fad. They outdate every drug on the market and were used by some of the first physicians in history. It is important to continue research into the antimicrobial effects of essential oils, as they may hold the secret to treatment options with the continued rise of multidrug-resistant organisms. The danger of these oils lies not in their hidden potential but in the belief that natural things are safe. A few animal studies have been performed, but little is known about the full effects of essential oils in humans. Patients need to be educated that these are not panaceas with freedom from side effects and that treatment options backed by the scientific method should be their first choice under the supervision of trained physicians.

The legal problem with selling and classifying essential oils is that the US Food and Drug Administration requires products intended for treatment to be labeled as drugs, which hinders their sales on the open market.13 It all boils down to intended use, so some companies sell the oils under a food or fragrance classification with vague instructions on how to use said oil for medicinal purposes, which leads to lack of supervision, anecdotal cures, and false health claims. One company claims in their safety guide for topical applications of their oils that “[i]f a rash occurs, this may be a sign of detoxification.”15 If essential oils had only minimal absorption topically, their safety would be less concerning, but this does not appear to be the case.
Absorption and Systemics
The effects of essential oils on the skin is one aspect of their use to be studied; another is the more systemic effects from absorption through the skin. Most essential oils used in small quantities for fragrance in over-the-counter lotions prove only to be an issue for allergens in sensitive patient groups. However, topical applications of essential oils in their pure concentrated form get absorbed into the skin faster than if used with a carrier oil, emulsion, or solvent.16 For most minor uses of essential oils, the body can detoxify absorbed chemicals the same way it does when a person eats the plants the oils came from (eg, basil essential oils leaching from the leaves into a tomato sauce). A possible danger of the oils’ systemic properties lies in the pregnant patient population who use essential oils thinking that natural is safe.
Many essential oils, such as lavender (L officinalis), exhibit hormonal mimicry with phytoestrogens and can produce emmenagogue (increasing menstrual flow) effects in women. Other oils, such as those of nutmeg (Myristica fragrans) and myrrh (Commiphora myrrha), can have abortifacient effects. These natural essential oils can lead to unintended health risks for mother and baby.17 With implications this serious, many essential oil companies put pregnancy warnings on most if not all of their products, but pregnant patients may not always note the risk.
Conclusion
Essential oils are not the newest medical fad. They outdate every drug on the market and were used by some of the first physicians in history. It is important to continue research into the antimicrobial effects of essential oils, as they may hold the secret to treatment options with the continued rise of multidrug-resistant organisms. The danger of these oils lies not in their hidden potential but in the belief that natural things are safe. A few animal studies have been performed, but little is known about the full effects of essential oils in humans. Patients need to be educated that these are not panaceas with freedom from side effects and that treatment options backed by the scientific method should be their first choice under the supervision of trained physicians. The Table outlines the uses and side effects of the essential oils discussed here.
What Are Essential Oils?
Essential oils are aromatic volatile oils produced by medicinal plants that give them their distinct flavors and aromas. They are extracted using a variety of different techniques, such as microwave-assisted extraction, headspace extraction, and the most commonly employed hydrodistillation.1 Different parts of the plant are used for the specific oils; the shoots and leaves of Origanum vulgare are used for oregano oil, whereas the skins of Citrus limonum are used for lemon oil.2 Historically, essential oils have been used for cooking, food preservation, perfume, and medicine.3,4
Historical Uses for Essential Oils
Essential oils and their intact medicinal plants were among the first medicines widely available to the ancient world. The Ancient Greeks used topical and oral oregano as a cure-all for ailments including wounds, sore muscles, and diarrhea. Because of its use as a cure-all medicine, it remains a popular folk remedy in parts of Europe today.3 Lavender also has a long history of being a cure-all plant and oil. Some of the many claims behind this flower include treatment of burns, insect bites, parasites, muscle spasms, nausea, and anxiety/depression.5 With an extensive list of historical uses, many essential oils are being researched to determine if their acclaimed qualities have quantifiable properties.
Science Behind the Belief
In vitro experiments with oregano (O vulgare) have demonstrated notable antifungal and antimicrobial effects.6 Gas chromatographic analysis of the oil shows much of it is composed of phenolic monoterpenes, such as thymol and carvacrol. They exhibit strong antifungal effects with a slightly stronger effect on the dermatophyte Trichophyton rubrum over other yeast species such as Candida.7,8 The full effect of the monoterpenes on fungi is not completely understood, but early data show it has a strong affinity for the ergosterol used in the cell-wall synthesis. Other effects demonstrated in in vitro studies include the ability to block drug efflux pumps, biofilm formation, cellular communication among bacteria, and mycotoxin production.9
A double-blind, randomized trial by Akhondzadeh et al10 demonstrated lavender (Lavandula officinalis) to have a mild antidepressant quality but a noticeably more potent effect when combined with imipramine. The effects of the lavender with imipramine were stronger and provided earlier improvement than imipramine alone for treatment of mild to moderate depression. The team concluded that lavender may be an effective adjunct therapy in treating depression.10
In a study by Mori et al,11 full-thickness circular wounds were made in rats and treated with either lavender oil (L officinalis), nothing, or a control oil. With the lavender oil being at only 1% solution, the wounds treated with lavender oil demonstrated earlier closure than the other 2 groups of wounds, where no major difference was noted. On cellular analysis, it was seen that the lavender had increased the rate of granulation as well as expression of types I and III collagen. The most striking result was the large expression of transforming growth factor β seen in the lavender group compared to the others. The final thoughts on this experiment were that lavender may provide new approaches to wound care in the future.11
Potential Problems With Purity
One major concern raised about essential oils is their purity and the fidelity of their chemical composition. The specific aromatic chemicals in each essential oil are maintained for each species, but the proportions of each change even with the time of year.12 Gas chromatograph analysis of the same oil distilled with different techniques showed that the proportions of aromatic chemicals varied with technique. However, the major constituents of the oil remained present in large quantities, just at different percentages.1 Even using the same distillation technique for different time periods can greatly affect the yield and composition of the oil. Although the percentage of each aromatic compound can be affected by distillation times, the antioxidant and antimicrobial effects of the oil remain constant regardless of these variables.2 There is clearly a lack in standardization in essential oil production, which may not be an issue for its use in complementary medicine if its properties are maintained regardless.
Safety Concerns and Regulations
With essential oils being a natural cure for everyday ailments, some people are turning first to oils for every cut and bruise. The danger in these natural cures is that essential oils can cause several types of dermatitis and allergic reactions. The development of allergies to essential oils is at an even higher risk, considering people frequently put them on wounds and rashes where the skin barrier is already weakened. Many essential oils fall into the fragrance category in patch tests, negating the widely circulating blogger and online reports that essential oils cannot cause allergies.
Some of the oils, although regarded safe by the US Food and Drug Administration for consumption, can cause dermatitis from simple contact or with sun exposure.13 Members of the citrus family are notorious for the phytophotodermatitis reaction, which can leave hyperpigmented scarring after exposure of the oils to sunlight.14 Most companies that sell essential oils are aware of this reaction and include it in the warning labels.

Practice Points
- Essential oils are a rising trend of nonprescribed topical supplements used by patients to self-treat.
- Research into historically medicinal essential oils may unlock treatment opportunities in the near future.
- Keeping an open-minded line of communication is critical for divulgence of potential home remedies that could be causing patients harm.
- Understanding the mindset of the essential oil–using community is key to building trust and treating these patients who are often distrusting of Western medicine.
Mobile Apps for Professional Dermatology Education: An Objective Review
With today’s technology, it is easier than ever to access web-based tools that enrich traditional dermatology education. The literature supports the use of these innovative platforms to enhance learning at the student and trainee levels. A controlled study of pediatric residents showed that online modules effectively supplemented clinical experience with atopic dermatitis.1 In a randomized diagnostic study of medical students, practice with an image-based web application (app) that teaches rapid recognition of melanoma proved more effective than learning a rule-based algorithm.2 Given the visual nature of dermatology, pattern recognition is an essential skill that is fostered through experience and is only made more accessible with technology.
With the added benefit of convenience and accessibility, mobile apps can supplement experiential learning. Mirroring the overall growth of mobile apps, the number of available dermatology apps has increased.3 Dermatology mobile apps serve purposes ranging from quick reference tools to comprehensive modules, journals, and question banks. At an academic hospital in Taiwan, both nondermatology and dermatology trainees’ examination performance improved after 3 weeks of using a smartphone-based wallpaper learning module displaying morphologic characteristics of fungi.4 With the expansion of virtual microscopy, mobile apps also have been created as a learning tool for dermatopathology, giving trainees the flexibility and autonomy to view slides on their own time.5 Nevertheless, the literature on dermatology mobile apps designed for the education of medical students and trainees is limited, demonstrating a need for further investigation.
Prior studies have reviewed dermatology apps for patients and practicing dermatologists.6-8 Herein, we focus on mobile apps targeting students and residents learning dermatology. General dermatology reference apps and educational aid apps have grown by 33% and 32%, respectively, from 2014 to 2017.3 As with any resource meant to educate future and current medical providers, there must be an objective review process in place to ensure accurate, unbiased, evidence-based teaching.
Well-organized, comprehensive information and a user-friendly interface are additional factors of importance when selecting an educational mobile app. When discussing supplemental resources, accessibility and affordability also are priorities given the high cost of a medical education at baseline. Overall, there is a need for a standardized method to evaluate the key factors of an educational mobile app that make it appropriate for this demographic. We conducted a search of mobile apps relating to dermatology education for students and residents.
Methods
We searched for publicly available mobile apps relating to dermatology education in the App Store (Apple Inc) from September to November 2019 using the search terms dermatology education, dermoscopy education, melanoma education, skin cancer education, psoriasis education, rosacea education, acne education, eczema education, dermal fillers education, and Mohs surgery education. We excluded apps that were not in English, were created for a conference, cost more than $5 to download, or did not include a specific dermatology education section. In this way, we hoped to evaluate apps that were relevant, accessible, and affordable.
We modeled our study after a review of patient education apps performed by Masud et al6 and utilized their quantified grading rubric (scale of 1 to 4). We found their established criteria—educational objectives, content, accuracy, design, and conflict of interest—to be equally applicable for evaluating apps designed for professional education.6 Each app earned a minimum of 1 point and a maximum of 4 points per criterion. One point was given if the app did not fulfill the criterion, 2 points for minimally fulfilling the criterion, 3 points for mostly fulfilling the criterion, and 4 points if the criterion was completely fulfilled. Two medical students (E.H. and N.C.)—one at the preclinical stage and the other at the clinical stage of medical education—reviewed the apps using the given rubric, then discussed and resolved any discrepancies in points assigned. A dermatology resident (M.A.) independently reviewed the apps using the given rubric.
The mean of the student score and the resident score was calculated for each category. The sum of the averages for each category was considered the final score for an app, determining its overall quality. Apps with a total score of 5 to 10 were considered poor and inadequate for education. A total score of 10.5 to 15 indicated that an app was somewhat adequate (ie, useful for education in some aspects but falling short in others). Apps that were considered adequate for education, across all or most criteria, received a total score ranging from 15.5 to 20.
Results
Our search generated 130 apps. After applying exclusion criteria, 42 apps were eligible for review. At the time of publication, 36 of these apps were still available. The possible range of scores based on the rubric was 5 to 20. The actual range of scores was 7 to 20. Of the 36 apps, 2 (5.6%) were poor, 16 (44.4%) were somewhat adequate, and 18 (50%) were adequate. Formats included primary resources, such as clinical decision support tools, journals, references, and a podcast (Table 1). Additionally, interactive learning tools included games, learning modules, and apps for self-evaluation (Table 2). Thirty apps covered general dermatology; others focused on skin cancer (n=5) and cosmetic dermatology (n=1). Regarding cost, 29 apps were free to download, whereas 7 charged a fee (mean price, $2.56).
Comment
In addition to the convenience of having an educational tool in their white-coat pocket, learners of dermatology have been shown to benefit from supplementing their curriculum with mobile apps, which sets the stage for formal integration of mobile apps into dermatology teaching in the future.8 Prior to widespread adoption, mobile apps must be evaluated for content and utility, starting with an objective rubric.
Without official scientific standards in place, it was unsurprising that only half of the dermatology education applications were classified as adequate in this study. Among the types of apps offered—clinical decision support tools, journals, references, podcast, games, learning modules, and self-evaluation—certain categories scored higher than others. App formats with the highest average score (16.5 out of 20) were journals and podcast.
One barrier to utilization of these apps was that a subscription to the journals and podcast was required to obtain access to all available content. Students and trainees can seek out library resources at their academic institutions to take advantage of journal subscriptions available to them at no additional cost. Dermatology residents can take advantage of their complimentary membership in the American Academy of Dermatology for a free subscription to AAD Dialogues in Dermatology (otherwise $179 annually for nonresident members and $320 annually for nonmembers).
On the other hand, learning module was the lowest-rated format (average score, 11.3 out of 20), with only Medical Student: Dermatology qualifying as adequate (total score, 16). This finding is worrisome given that students and residents might look to learning modules for quick targeted lessons on specific topics.
The lowest-scoring app, a clinical decision support tool called Naturelize, received a total score of 7. Although it listed the indications and contraindications for dermal filler types to be used in different locations on the face, there was a clear conflict of interest, oversimplified design, and little evidence-based education, mirroring the current state of cosmetic dermatology training in residency, in which trainees think they are inadequately prepared for aesthetic procedures and comparative effectiveness research is lacking.9-11
At the opposite end of the spectrum, MyDermPath+ was a reference app with a total score of 20. The app cited credible authors with a medical degree (MD) and had an easy-to-use, well-designed interface, including a reference guide, differential builder, and quiz for a range of topics within dermatology. As a free download without in-app purchases or advertisements, there was no evidence of conflict of interest. The position of a dermatopathology app as the top dermatology education mobile app might reflect an increased emphasis on dermatopathology education in residency as well as a transition to digitization of slides.5
The second-highest scoring apps (total score of 19 points) were Dermatology Database and VisualDx. Both were references covering a wide range of dermatology topics. Dermatology Database was a comprehensive search tool for diseases, drugs, procedures, and terms that was simple and entirely free to use but did not cite references. VisualDx, as its name suggests, offered quality clinical images, complete guides with references, and a unique differential builder. An annual subscription is $399.99, but the process to gain free access through a participating academic institution was simple.
Games were a unique mobile app format; however, 2 of 3 games scored in the somewhat adequate range. The game DiagnosUs, which tested users’ ability to differentiate skin cancer and psoriasis from dermatitis on clinical images, would benefit from more comprehensive content as well as professional verification of true diagnoses, which earned the app 2 points in both the content and accuracy categories. The Unusual Suspects tested the ABCDE algorithm in a short learning module, followed by a simple game that involved identification of melanoma in a timed setting. Although the design was novel and interactive, the game was limited to the same 5 melanoma tumors overlaid on pictures of normal skin. The narrow scope earned 1 point for content, the redundancy in the game earned 3 points for design, and the lack of real clinical images earned 2 points for educational objectives. Although game-format mobile apps have the capability to challenge the user’s knowledge with a built-in feedback or reward system, improvements should be made to ensure that apps are equally educational as they are engaging.
AAD Dialogues in Dermatology was the only app in the form of a podcast and provided expert interviews along with disclosures, transcripts, commentary, and references. More than half the content in the app could not be accessed without a subscription, earning 2.5 points in the conflict of interest category. Additionally, several flaws resulted in a design score of 2.5, including inconsistent availability of transcripts, poor quality of sound on some episodes, difficulty distinguishing new episodes from those already played, and a glitch that removed the episode duration. Still, the app was a valuable and comprehensive resource, with clear objectives and cited references. With improvements in content, affordability, and user experience, apps in unique formats such as games and podcasts might appeal to kinesthetic and auditory learners.
An important factor to consider when discussing mobile apps for students and residents is cost. With rising prices of board examinations and preparation materials, supplementary study tools should not come with an exorbitant price tag. Therefore, we limited our evaluation to apps that were free or cost less than $5 to download. Even so, subscriptions and other in-app purchases were an obstacle in one-third of apps, ranging from $4.99 to unlock additional content in Rash Decisions to $69.99 to access most topics in Fitzpatrick’s Color Atlas. The highest-rated app in our study, MyDermPath+, historically cost $19.99 to download but became free with a grant from the Sulzberger Foundation.12 An initial investment to develop quality apps for the purpose of dermatology education might pay off in the end.
To evaluate the apps from the perspective of the target demographic of this study, 2 medical students—one in the preclinical stage and the other in the clinical stage of medical education—and a dermatology resident graded the apps. Certain limitations exist in this type of study, including differing learning styles, which might influence the types of apps that evaluators found most impactful to their education. Interestingly, some apps earned a higher resident score than student score. In particular, RightSite (a reference that helps with anatomically correct labeling) and Mohs Surgery Appropriate Use Criteria (a clinical decision support tool to determine whether to perform Mohs surgery) each had a 3-point discrepancy (data not shown). A resident might benefit from these practical apps in day-to-day practice, but a student would be less likely to find them useful as a learning tool.
Still, by defining adequate teaching value using specific categories of educational objectives, content, accuracy, design, and conflict of interest, we attempted to minimize the effect of personal preference on the grading process. Although we acknowledge a degree of subjectivity, we found that utilizing a previously published rubric with defined criteria was crucial in remaining unbiased.
Conclusion
Further studies should evaluate additional apps available on Apple’s iPad (tablet), as well as those on other operating systems, including Google’s Android. To ensure the existence of mobile apps as adequate education tools, they should be peer reviewed prior to publication or before widespread use by future and current providers at the minimum. To maximize free access to highly valuable resources available in the palm of their hand, students and trainees should contact the library at their academic institution.

With today’s technology, it is easier than ever to access web-based tools that enrich traditional dermatology education. The literature supports the use of these innovative platforms to enhance learning at the student and trainee levels. A controlled study of pediatric residents showed that online modules effectively supplemented clinical experience with atopic dermatitis.1 In a randomized diagnostic study of medical students, practice with an image-based web application (app) that teaches rapid recognition of melanoma proved more effective than learning a rule-based algorithm.2 Given the visual nature of dermatology, pattern recognition is an essential skill that is fostered through experience and is only made more accessible with technology.
With the added benefit of convenience and accessibility, mobile apps can supplement experiential learning. Mirroring the overall growth of mobile apps, the number of available dermatology apps has increased.3 Dermatology mobile apps serve purposes ranging from quick reference tools to comprehensive modules, journals, and question banks. At an academic hospital in Taiwan, both nondermatology and dermatology trainees’ examination performance improved after 3 weeks of using a smartphone-based wallpaper learning module displaying morphologic characteristics of fungi.4 With the expansion of virtual microscopy, mobile apps also have been created as a learning tool for dermatopathology, giving trainees the flexibility and autonomy to view slides on their own time.5 Nevertheless, the literature on dermatology mobile apps designed for the education of medical students and trainees is limited, demonstrating a need for further investigation.
Prior studies have reviewed dermatology apps for patients and practicing dermatologists.6-8 Herein, we focus on mobile apps targeting students and residents learning dermatology. General dermatology reference apps and educational aid apps have grown by 33% and 32%, respectively, from 2014 to 2017.3 As with any resource meant to educate future and current medical providers, there must be an objective review process in place to ensure accurate, unbiased, evidence-based teaching.
Well-organized, comprehensive information and a user-friendly interface are additional factors of importance when selecting an educational mobile app. When discussing supplemental resources, accessibility and affordability also are priorities given the high cost of a medical education at baseline. Overall, there is a need for a standardized method to evaluate the key factors of an educational mobile app that make it appropriate for this demographic. We conducted a search of mobile apps relating to dermatology education for students and residents.
Methods
We searched for publicly available mobile apps relating to dermatology education in the App Store (Apple Inc) from September to November 2019 using the search terms dermatology education, dermoscopy education, melanoma education, skin cancer education, psoriasis education, rosacea education, acne education, eczema education, dermal fillers education, and Mohs surgery education. We excluded apps that were not in English, were created for a conference, cost more than $5 to download, or did not include a specific dermatology education section. In this way, we hoped to evaluate apps that were relevant, accessible, and affordable.
We modeled our study after a review of patient education apps performed by Masud et al6 and utilized their quantified grading rubric (scale of 1 to 4). We found their established criteria—educational objectives, content, accuracy, design, and conflict of interest—to be equally applicable for evaluating apps designed for professional education.6 Each app earned a minimum of 1 point and a maximum of 4 points per criterion. One point was given if the app did not fulfill the criterion, 2 points for minimally fulfilling the criterion, 3 points for mostly fulfilling the criterion, and 4 points if the criterion was completely fulfilled. Two medical students (E.H. and N.C.)—one at the preclinical stage and the other at the clinical stage of medical education—reviewed the apps using the given rubric, then discussed and resolved any discrepancies in points assigned. A dermatology resident (M.A.) independently reviewed the apps using the given rubric.
The mean of the student score and the resident score was calculated for each category. The sum of the averages for each category was considered the final score for an app, determining its overall quality. Apps with a total score of 5 to 10 were considered poor and inadequate for education. A total score of 10.5 to 15 indicated that an app was somewhat adequate (ie, useful for education in some aspects but falling short in others). Apps that were considered adequate for education, across all or most criteria, received a total score ranging from 15.5 to 20.
Results
Our search generated 130 apps. After applying exclusion criteria, 42 apps were eligible for review. At the time of publication, 36 of these apps were still available. The possible range of scores based on the rubric was 5 to 20. The actual range of scores was 7 to 20. Of the 36 apps, 2 (5.6%) were poor, 16 (44.4%) were somewhat adequate, and 18 (50%) were adequate. Formats included primary resources, such as clinical decision support tools, journals, references, and a podcast (Table 1). Additionally, interactive learning tools included games, learning modules, and apps for self-evaluation (Table 2). Thirty apps covered general dermatology; others focused on skin cancer (n=5) and cosmetic dermatology (n=1). Regarding cost, 29 apps were free to download, whereas 7 charged a fee (mean price, $2.56).
Comment
In addition to the convenience of having an educational tool in their white-coat pocket, learners of dermatology have been shown to benefit from supplementing their curriculum with mobile apps, which sets the stage for formal integration of mobile apps into dermatology teaching in the future.8 Prior to widespread adoption, mobile apps must be evaluated for content and utility, starting with an objective rubric.
Without official scientific standards in place, it was unsurprising that only half of the dermatology education applications were classified as adequate in this study. Among the types of apps offered—clinical decision support tools, journals, references, podcast, games, learning modules, and self-evaluation—certain categories scored higher than others. App formats with the highest average score (16.5 out of 20) were journals and podcast.
One barrier to utilization of these apps was that a subscription to the journals and podcast was required to obtain access to all available content. Students and trainees can seek out library resources at their academic institutions to take advantage of journal subscriptions available to them at no additional cost. Dermatology residents can take advantage of their complimentary membership in the American Academy of Dermatology for a free subscription to AAD Dialogues in Dermatology (otherwise $179 annually for nonresident members and $320 annually for nonmembers).
On the other hand, learning module was the lowest-rated format (average score, 11.3 out of 20), with only Medical Student: Dermatology qualifying as adequate (total score, 16). This finding is worrisome given that students and residents might look to learning modules for quick targeted lessons on specific topics.
The lowest-scoring app, a clinical decision support tool called Naturelize, received a total score of 7. Although it listed the indications and contraindications for dermal filler types to be used in different locations on the face, there was a clear conflict of interest, oversimplified design, and little evidence-based education, mirroring the current state of cosmetic dermatology training in residency, in which trainees think they are inadequately prepared for aesthetic procedures and comparative effectiveness research is lacking.9-11
At the opposite end of the spectrum, MyDermPath+ was a reference app with a total score of 20. The app cited credible authors with a medical degree (MD) and had an easy-to-use, well-designed interface, including a reference guide, differential builder, and quiz for a range of topics within dermatology. As a free download without in-app purchases or advertisements, there was no evidence of conflict of interest. The position of a dermatopathology app as the top dermatology education mobile app might reflect an increased emphasis on dermatopathology education in residency as well as a transition to digitization of slides.5
The second-highest scoring apps (total score of 19 points) were Dermatology Database and VisualDx. Both were references covering a wide range of dermatology topics. Dermatology Database was a comprehensive search tool for diseases, drugs, procedures, and terms that was simple and entirely free to use but did not cite references. VisualDx, as its name suggests, offered quality clinical images, complete guides with references, and a unique differential builder. An annual subscription is $399.99, but the process to gain free access through a participating academic institution was simple.
Games were a unique mobile app format; however, 2 of 3 games scored in the somewhat adequate range. The game DiagnosUs, which tested users’ ability to differentiate skin cancer and psoriasis from dermatitis on clinical images, would benefit from more comprehensive content as well as professional verification of true diagnoses, which earned the app 2 points in both the content and accuracy categories. The Unusual Suspects tested the ABCDE algorithm in a short learning module, followed by a simple game that involved identification of melanoma in a timed setting. Although the design was novel and interactive, the game was limited to the same 5 melanoma tumors overlaid on pictures of normal skin. The narrow scope earned 1 point for content, the redundancy in the game earned 3 points for design, and the lack of real clinical images earned 2 points for educational objectives. Although game-format mobile apps have the capability to challenge the user’s knowledge with a built-in feedback or reward system, improvements should be made to ensure that apps are equally educational as they are engaging.
AAD Dialogues in Dermatology was the only app in the form of a podcast and provided expert interviews along with disclosures, transcripts, commentary, and references. More than half the content in the app could not be accessed without a subscription, earning 2.5 points in the conflict of interest category. Additionally, several flaws resulted in a design score of 2.5, including inconsistent availability of transcripts, poor quality of sound on some episodes, difficulty distinguishing new episodes from those already played, and a glitch that removed the episode duration. Still, the app was a valuable and comprehensive resource, with clear objectives and cited references. With improvements in content, affordability, and user experience, apps in unique formats such as games and podcasts might appeal to kinesthetic and auditory learners.
An important factor to consider when discussing mobile apps for students and residents is cost. With rising prices of board examinations and preparation materials, supplementary study tools should not come with an exorbitant price tag. Therefore, we limited our evaluation to apps that were free or cost less than $5 to download. Even so, subscriptions and other in-app purchases were an obstacle in one-third of apps, ranging from $4.99 to unlock additional content in Rash Decisions to $69.99 to access most topics in Fitzpatrick’s Color Atlas. The highest-rated app in our study, MyDermPath+, historically cost $19.99 to download but became free with a grant from the Sulzberger Foundation.12 An initial investment to develop quality apps for the purpose of dermatology education might pay off in the end.
To evaluate the apps from the perspective of the target demographic of this study, 2 medical students—one in the preclinical stage and the other in the clinical stage of medical education—and a dermatology resident graded the apps. Certain limitations exist in this type of study, including differing learning styles, which might influence the types of apps that evaluators found most impactful to their education. Interestingly, some apps earned a higher resident score than student score. In particular, RightSite (a reference that helps with anatomically correct labeling) and Mohs Surgery Appropriate Use Criteria (a clinical decision support tool to determine whether to perform Mohs surgery) each had a 3-point discrepancy (data not shown). A resident might benefit from these practical apps in day-to-day practice, but a student would be less likely to find them useful as a learning tool.
Still, by defining adequate teaching value using specific categories of educational objectives, content, accuracy, design, and conflict of interest, we attempted to minimize the effect of personal preference on the grading process. Although we acknowledge a degree of subjectivity, we found that utilizing a previously published rubric with defined criteria was crucial in remaining unbiased.
Conclusion
Further studies should evaluate additional apps available on Apple’s iPad (tablet), as well as those on other operating systems, including Google’s Android. To ensure the existence of mobile apps as adequate education tools, they should be peer reviewed prior to publication or before widespread use by future and current providers at the minimum. To maximize free access to highly valuable resources available in the palm of their hand, students and trainees should contact the library at their academic institution.

Practice Points
- Mobile applications (apps) are a convenient way to learn dermatology, but there is no objective method to assess their quality.
- To determine which apps are most useful for education, we performed a graded review of dermatology apps targeted to students and residents.
- By applying a rubric to 36 affordable apps, we identified 18 (50%) with adequate teaching value.
