Picosecond 755-nm laser found effective for neck rejuvenation
DALLAS –
“It’s important to note that response was variable, but many patients were satisfied with the treatment,” Hana Jeon, MD said at the annual conference of the American Society for Laser Medicine and Surgery, Inc. “Further studies are needed to identify the clinical characteristics of neck laxity that would most benefit from this treatment.”
Dr. Jeon, a dermatologist at the Laser & Skin Surgery Center of New York, and her associates examined the safety and efficacy of the treatment of skin laxity on the neck using a picosecond 755-nm laser with focus lens array, which uses a diffractive lens to redistribute the energy at both low- and high-intensity energies. “High-intensity energy leads to cellular changes, which then results in dermal remodeling,” she said. “This technology has been shown to be helpful for acne scar treatment and skin rejuvenation. A big advantage of this technology is that there is really no downtime other than transient erythema. Given that both collagen and elastin have been shown to increase over time after treatment, we decided to evaluate its role in treating neck laxity.”
The researchers enrolled 25 patients with an average age of 58 years. The laser treatment settings were a 6-mm spot side-delivered at a fluence of 0.71 J/cm2 in a pulse width of 750 picoseconds. The patients were treated five times on the neck every 2-4 weeks, and follow-up visits were scheduled for 1 month and 3 months after the last treatment. Digital photos were taken at each visit. Formal assessment tools included patient and physician satisfaction scores and the Global Aesthetic Improvement Scale. In all, 21 women and 3 men completed the study. The majority (72%) had Fitzpatrick skin type II, while 16% had type III, 8% had type I, and 4% had type IV. An average of 5,042 pulses were delivered during each treatment session. The majority of patients (84%) required no anesthesia, while the rest used topical numbing medicine from 30 minutes to an hour prior to the procedure.
Dr. Jeon reported that the average pain score during the procedure was 4.7 on a 10-point scale. Forced-air cooling was used for comfort, and on average, mild redness following the treatment lasted less than 1 day (a mean of 0.6 days, with a range of 0-5 days). Mild pain also lasted less than 1 day (a mean of 0.1 days, with a range of 0-2 days). No swelling, crusting, bruising, bleeding, infection, blistering, scarring, burn, or dyspigmentation occurred.
Analysis of satisfaction scores at 3-month follow-up revealed that 43% of patients and 36% of physicians, respectively, felt “neutral” about the results, 30% and 27%, respectively, reported being “satisfied” with the results, and 13% and 14%, respectively, reported being “extremely satisfied” with the results.
On the Global Aesthetic Improvement Scale at 1 and 3 months, physicians described 43% and 23% of cases, respectively, as “improved,” 17% and 18% of cases as “much improved,” and 4% and 9% of cases as “extremely improved.”
At 3 months, 35% of patients said they would be “somewhat likely” to recommend the procedure, and 30% said they would be “extremely likely” to recommend it.
Dr. Jeon reported having no financial disclosures.

Consider hydroxychloroquine in treating pediatric alopecia areata
according to Duri Yun, MD, of the University of Chicago Medicine, and associates.
In a retrospective review published in Pediatric Dermatology, nine children aged 6-16 years with AA and diverse ethnicities were treated with hydroxychloroquine between July 1, 2013, and July 1, 2015; all had failed multiple previous treatment modalities. In patient 1, hydroxychloroquine therapy was initiated, fine hair regrowth occurred after 5 months of therapy and was maintained, with dosage tapered to 200 mg once daily after 1 year. After 2 years of therapy, hair had nearly completely regrown. Similar results occurred in patient 2, who had nearly complete hair loss within 2 weeks of initiating hydroxychloroquine. Steady regrowth continued to near-complete regrowth after 1 year of treatment, when dosage was tapered to 200 mg once daily.
Four patients (44%) had no evidence of regrowth after 4-6 months of hydroxychloroquine therapy so they discontinued therapy. The most common adverse events while taking hydroxychloroquine were abdominal pain in two patients (22%) and headache in two patients (22%).
“In the context of children with severe AA failing multiple first-line therapies, our findings suggest that there may be a subgroup that benefits from therapy with hydroxychloroquine,” the researchers concluded. “Determining which factors might predict response to various therapies will come from combined efforts to conduct well-controlled clinical trials of treatments for AA.”

Alopecia areata has female predominance, more severe types common in boys
reported Iris Wohlmuth-Wieser, MD, of the department of dermatology, MD Anderson Cancer Center, Houston, and her associates, who conducted a large review of U.S. registry data.
Although it is the third most common dermatosis in children, there are not much data on AA in children, so the researchers used information from the National Alopecia Areata Registry, which was established in 2000. First, interested patients and parents were contacted and asked to fill out a web-based screening questionnaire. In the second phase, they were asked to fill out a more extensive survey and visit one of five U.S. sites for a clinical exam by a dermatologist.
Of the 2,218 children and teens who completed the initial questionnaire, the mean age at the time of the survey was 10 years, and their mean age of onset of AA was 6 years. The female to male ratio was 1.5:1; boys were significantly more likely to have severe types of AA (P = .009). Most patients (70%) were white, followed by mixed ethnicity (11%), Hispanic (3%), and then other ethnicities. About 3% of patients said they had a sibling with AA, 14% said that another first-degree relative had AA, and 8% said that at least three first-degree relatives had AA.
In terms of the degree of hair loss, 45% lost all scalp hair, 31% lost all body hair, and 14% lost all nails.
Concomitant diseases were reported by 47% of the responders, with atopic dermatitis, asthma, hay fever, and allergies the most common.
Of the 643 children and teens who completed a more detailed questionnaire and underwent clinical examination, 63% were female; 26% had at least one relative with AA and 8% had at least three first-degree relatives with AA. Almost 4% had congenital AA.
At the physical exam, there were data on the amount of hair loss in 617 children: Of these children, 37% had lost all scalp hair and 19% had lost up to three-quarters of their scalp hair. In 618 children (in whom information on body hair loss was obtained at the physical exam), 72% lost all or some of their body hair. Information on nails was available in 609 children; in this group, 44% had some nail involvement. More detailed information was available in 290 children; in this group, findings included pitting in 86%, dystrophy in 10%, onycholysis in 2%, ridging in 1%, and onychomycosis in 1%.
Commenting on the 25 children who presented with congenital AA, the authors wrote that this is “an extremely rare and infrequently reported form of AA.
“This is an interesting and important finding, because AA has traditionally been described as an acquired disease,” they added.
In their cohort overall, 25% had a family history of AA, with 8% having more than three first-degree relatives with AA. The researchers said that the percentage of children with AA and a positive family history ranges from 8% to 52% in the literature.
“The predominant presentation of AA types in our cohort (61.4%) was severe hair loss (76%-100% of scalp hair loss). This is comparable with a European study reporting a prevalence of 65%. Other studies on childhood AA conducted in Asian and Arab populations observed mainly mild cases,” they wrote.
Nail involvement, often reported with AA, was evident in 39% of patients who completed the questionnaire online and in 44% on physical exam. This agreed with the 26%-40% involvement reported in the literature.
There were no conflicts of interest or funding information reported.

Clinical pattern may help distinguish pediatric NMN from subungal melanoma
When longitudinal melanonychia appears as a sharply demarcated pigment band of even width against normal nail in a child, Hutchinson’s sign with longitudinal brushy pigmentation may be a useful clinical pattern suggesting a diagnosis of nail matrix nevus rather than subungual melanoma, said Jae Ho Lee, MD, of Sungkyunkwan University, Seoul, South Korea, and associates.
Hutchinson’s sign was seen in seven pediatric patients, but no adult patients. In most cases, Hutchinson’s sign had hyponychial pigmentation, and on dermoscopy showed a pigment pattern presenting longitudinally and resembling a brush mark (longitudinal brushy pigmentation or LBP). LBP of nail matrix nevi is different from the Hutchinson’s sign that occurs in subungual melanoma (SUM), where it is typically a “haphazard pigmentation pattern involving periungual skin.
“We propose that Hutchinson’s sign occurs more commonly in pediatric NMN than in adult NMN, and that the presence of the LBP pattern can help distinguish pediatric NMN from SUM,” the investigators said.
Histologically, the biopsies of the NMN in this study showed some important differences from known SUM histology. All the study biopsies “showed a melanocytic proliferation exhibiting a predominantly nested growth pattern, with the nests mostly located at the dermoepithelial junction and with retraction artifact surrounding the nests. There were variable nuclear hyperchromatism, nuclear sizes, and cytologic atypia within the NMN biopsy specimens,” the researchers said. “In contrast, the histology of SUM demonstrates a predominance of atypical single melanocytes over nests, retraction artifacts around individual melanocytes, and uniform atypia of melanocytes throughout the biopsy specimen.”

VIDEO: Device-based therapy for onychomycosis
REPORTING FROM AAD 18
SAN DIEGO – which has been studied in two clinical trials and case series, Shari Lipner, MD, PhD, said in a video interview at the annual meeting of the American Academy of Dermatology, where she presented on this topic.
“Something that we’re looking at is plasma treatment of onychomycosis basically using ionized gas,” which has been shown to inhibit the growth of Trichophyton rubrum in vitro, added Dr. Lipner of the department of dermatology, Cornell University, New York.
In a pilot study of 19 patients with onychomycosis, she and her associates found that the clinical cure with nonthermal plasma was about 50% and the mycological cure rate was 15%, “and we’re now trying to improve efficacy using this device,” she said (Clin Exp Dermatol. 2017 Apr;42[3]:295-8). With a dielectric insulator, “nonthermal plasma is created by short pulses (about 10 ns) of strong (about 20 kV/mm peak) electric field that ionizes air molecules, creating ions and electrons, as well as ozone, hydroxyl radicals and nitric oxide,” according to the description in the study.
Other device-based therapies include iontophoresis, using electrical currents to increase drug delivery, and creating small punch biopsies or using a device to create “microholes” in the nails to increase delivery of topical medication across the nail, Dr. Lipner said.
Patients often ask about another device-based treatment, laser therapy, which she pointed out is not approved by the Food and Drug Administration for cure, but for a temporary increase in clear nail in patients with onychomycosis, “very different” than the criteria used for topical and systemic medications, making it difficult to compare efficacy data between lasers and medications, she noted.

SAN DIEGO – which has been studied in two clinical trials and case series, Shari Lipner, MD, PhD, said in a video interview at the annual meeting of the American Academy of Dermatology, where she presented on this topic.
“Something that we’re looking at is plasma treatment of onychomycosis basically using ionized gas,” which has been shown to inhibit the growth of Trichophyton rubrum in vitro, added Dr. Lipner of the department of dermatology, Cornell University, New York.
In a pilot study of 19 patients with onychomycosis, she and her associates found that the clinical cure with nonthermal plasma was about 50% and the mycological cure rate was 15%, “and we’re now trying to improve efficacy using this device,” she said (Clin Exp Dermatol. 2017 Apr;42[3]:295-8). With a dielectric insulator, “nonthermal plasma is created by short pulses (about 10 ns) of strong (about 20 kV/mm peak) electric field that ionizes air molecules, creating ions and electrons, as well as ozone, hydroxyl radicals and nitric oxide,” according to the description in the study.
Other device-based therapies include iontophoresis, using electrical currents to increase drug delivery, and creating small punch biopsies or using a device to create “microholes” in the nails to increase delivery of topical medication across the nail, Dr. Lipner said.
Patients often ask about another device-based treatment, laser therapy, which she pointed out is not approved by the Food and Drug Administration for cure, but for a temporary increase in clear nail in patients with onychomycosis, “very different” than the criteria used for topical and systemic medications, making it difficult to compare efficacy data between lasers and medications, she noted.

Onychomycosis Diagnosis and Long-term Treatment
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.

Phase 3 trials show halobetasol/tazarotene lotion works for psoriasis
KAUAI, HAWAII – in two phase 3 randomized, double-blind, multicenter clinical trials, Linda Stein Gold, MD, reported at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation.
The fixed combination of halobetasol 0.01%/tazarotene 0.045% lotion takes advantage of an observation made 20 years ago: When tazarotene is combined with a potent topical corticosteroid, therapeutic efficacy is amplified synergistically while the problematic local side effects of each agent are diminished, explained Dr. Stein Gold, director of dermatology research at the Henry Ford Health System, Detroit.
Tazarotene is approved for treatment of psoriasis in both its cream and gel formulations and at 0.1% and 0.05% concentrations, whereas only the 0.1% concentration is approved for acne. Yet when Dr. Stein Gold asked how many audience members prescribe tazarotene for their psoriasis patients, only a few tentative hands were raised.
“Tazarotene: Great for acne, but think of it again for psoriasis,” Dr. Stein Gold said. “It makes sense. Tazarotene improves differentiation of the skin; it decreases inflammation; it decreases proliferation – it does all the good things that we want to do for psoriasis.
“It’s got a little bit of baggage, though,” she continued. “It’s pregnancy Category X, so you have to make sure a woman who is or may become pregnant is not using it. And there are some side effects. It can be tough to use. When you use it in psoriasis you can get local irritation up to 30% of the time.”
The two parallel phase 3 randomized trials plus a separate phase 2 study, all of which Dr. Stein Gold was involved in, showed that the efficacy of the investigational halobetasol/tazarotene fixed combination was greater than either component alone, side effects were minimized, and efficacy remained durable 4 weeks after the 8-week treatment course ended.
The not-yet-published phase 3 trials included 418 patients with moderate to severe psoriasis randomized 2:1 to once-daily application of halobetasol/tazarotene or its vehicle for 8 weeks. Treatment success, defined as at least a two-grade improvement from baseline in Investigator’s Global Assessment score plus a score of clear or almost clear, was documented at 8 weeks in 35.8% of the halobetasol/tazarotene group in one study and 45.3% in the other, compared with 7% and 12.5% of controls, respectively.
In addition, after 8 weeks, affected body surface area was reduced by a mean of 32.8% in one study and by 42.5% in the other. There was also at least a two-grade improvement in plaque erythema at the target lesion site in 42.2% and 49.6% of halobetasol/tazarotene–treated patients in the two trials. A two-grade improvement in plaque elevation was noted in 59.3% and 59.7% of patients, while for plaque scaling, the figures were 59.4% and 62.9%.
“What we found in the two sister studies was statistically significant success in getting those plaques from moderate/severe all the way down to clear/almost clear,” Dr. Stein Gold said.
The most frequently reported treatment-emergent adverse events included contact dermatitis in 7.4% of the active treatment group and application site pain in 2.6%. Most side effects were mild or moderate in nature.
The phase 2 study, which included 212 psoriasis patients, looked specifically at maintenance of efficacy after end of treatment. Here, halobetasol/tazarotene showed durability of therapeutic benefit: 4 weeks after completing the 8-week course of once-daily halobetasol/tazarotene, 38.2% of patients still met the criteria for treatment success. The minimal skin atrophy that arose during treatment largely resolved during the subsequent 4 weeks off treatment.
The clinical trials were supported by Valeant. Dr. Stein Gold reported receiving research grants from and serving as a consultant to, paid speaker for, and scientific advisory board member for Valeant and numerous other pharmaceutical companies active in dermatologic drug development.

EXPERT ANALYSIS FROM SDEF HAWAII DERMATOLOGY SEMINAR
Refractory alopecia patients could consider a JAK inhibitor
SAN DIEGO – Treatment with a Janus kinase inhibitor such as tofacitinib is a reasonable option for patients with refractory alopecia who seek resolution of their hair loss and understand the adverse event risk from using this drug class, John E. Harris, MD, PhD, said at the annual meeting of the American Academy of Dermatology.
Using a Janus kinase (JAK) inhibitor to treat alopecia areata or totalis is a “highly successful, emerging therapy,” with efficacy rates for good responses of about a third or higher in a handful of published reports with experiences in more than 150 patients, said Dr. Harris, an associate professor of dermatology and director of the Vitiligo Clinic and Research Center at the University of Massachusetts Medical School in Worcester.
A review of the reported experience using tofacitinib to treat alopecia was recently published (J Investig Dermatol Symp Proc, 2018 Jan;19[1]:S18-S20). Although the incidence of shingles in patients treated with tofacitinib in trials was about 5%, no cases of this adverse event have yet been reported in alopecia patients who received the drug. The absence of shingles cases in the treated alopecia patients may be because they are generally much younger than the patients with rheumatic diseases who were in the trials, Dr. Harris suggested.
“Some clinicians may say ‘I’d never prescribe a JAK inhibitor for hair loss, it’s too dangerous,’ but several hundred alopecia patients have now received this with no serious adverse effects,” said Dr. Harris. He acknowledged, however, that eventually some patients treated this way will have serious adverse effects. He said that he is treating with tofacitinib a “handful” of alopecia patients who have been unresponsive to other treatments, are eager for an intervention that might regrow their hair, and who understand and accept the risk for developing an infection, shingles, or myelosuppression (with ruxolitinib treatment).
Roughly half of the alopecia patients prescribed tofacitinib (Xeljanz) by Dr. Harris have had their drug cost covered by health insurance, with the others paying for it themselves. Arranging for insurance coverage has usually involved filing an appeal, Dr. Harris said in an interview. The reported successful dosages have been 5 mg bid, with a boost to 10 mg bid for patients who don’t initially respond.
Insurance companies have not yet paid for treatment with ruxolitinib (Jakafi), which has been described in case reports in far fewer patients and which costs about $120,000 a year, he noted.
Dr. Harris said that JAK inhibitors also have great potential for treating vitiligo, a disorder he thinks shares many features in common with alopecia ( J Allergy Clin Immunol. 2017 Sept;140[3]:654-62).
“I think [JAK inhibitors] will have the same efficacy in vitiligo,” he predicted. He is particularly enthused about the possibility of administering ruxolitinib topically to patients with alopecia or vitiligo. Ruxolitinib is well suited to topical administration because of its good skin penetration, Dr. Harris said. Several trials now in progress are further studying JAK inhibitors for alopecia using oral or topical formulations.
Dr. Harris has been a consultant to and has received research funding from Pfizer, the company that markets tofacitinib (Xeljanz). He has also been a consultant to a dozen other companies, and has also received research support from Aclaris Therapeutics, Celgene, Dermavant, Genzyme, Sanofi, and Stiefel/GlaxoSmithKline.

Insurance companies have not yet paid for treatment with ruxolitinib (Jakafi), which has been described in case reports in far fewer patients and which costs about $120,000 a year, he noted.
Dr. Harris said that JAK inhibitors also have great potential for treating vitiligo, a disorder he thinks shares many features in common with alopecia ( J Allergy Clin Immunol. 2017 Sept;140[3]:654-62).
“I think [JAK inhibitors] will have the same efficacy in vitiligo,” he predicted. He is particularly enthused about the possibility of administering ruxolitinib topically to patients with alopecia or vitiligo. Ruxolitinib is well suited to topical administration because of its good skin penetration, Dr. Harris said. Several trials now in progress are further studying JAK inhibitors for alopecia using oral or topical formulations.
Dr. Harris has been a consultant to and has received research funding from Pfizer, the company that markets tofacitinib (Xeljanz). He has also been a consultant to a dozen other companies, and has also received research support from Aclaris Therapeutics, Celgene, Dermavant, Genzyme, Sanofi, and Stiefel/GlaxoSmithKline.
SAN DIEGO – Treatment with a Janus kinase inhibitor such as tofacitinib is a reasonable option for patients with refractory alopecia who seek resolution of their hair loss and understand the adverse event risk from using this drug class, John E. Harris, MD, PhD, said at the annual meeting of the American Academy of Dermatology.
Using a Janus kinase (JAK) inhibitor to treat alopecia areata or totalis is a “highly successful, emerging therapy,” with efficacy rates for good responses of about a third or higher in a handful of published reports with experiences in more than 150 patients, said Dr. Harris, an associate professor of dermatology and director of the Vitiligo Clinic and Research Center at the University of Massachusetts Medical School in Worcester.
A review of the reported experience using tofacitinib to treat alopecia was recently published (J Investig Dermatol Symp Proc, 2018 Jan;19[1]:S18-S20). Although the incidence of shingles in patients treated with tofacitinib in trials was about 5%, no cases of this adverse event have yet been reported in alopecia patients who received the drug. The absence of shingles cases in the treated alopecia patients may be because they are generally much younger than the patients with rheumatic diseases who were in the trials, Dr. Harris suggested.
“Some clinicians may say ‘I’d never prescribe a JAK inhibitor for hair loss, it’s too dangerous,’ but several hundred alopecia patients have now received this with no serious adverse effects,” said Dr. Harris. He acknowledged, however, that eventually some patients treated this way will have serious adverse effects. He said that he is treating with tofacitinib a “handful” of alopecia patients who have been unresponsive to other treatments, are eager for an intervention that might regrow their hair, and who understand and accept the risk for developing an infection, shingles, or myelosuppression (with ruxolitinib treatment).
Roughly half of the alopecia patients prescribed tofacitinib (Xeljanz) by Dr. Harris have had their drug cost covered by health insurance, with the others paying for it themselves. Arranging for insurance coverage has usually involved filing an appeal, Dr. Harris said in an interview. The reported successful dosages have been 5 mg bid, with a boost to 10 mg bid for patients who don’t initially respond.

EXPERT ANALYSIS AT AAD 18
Nail-Patella Syndrome: Clinical Clues for Making the Diagnosis
Nail-patella syndrome (NPS), also known as hereditary osteo-onychodysplasia syndrome, is a rare autosomal-dominant disorder with an estimated incidence of 1 per 50,000 individuals in the United States. Nail-patella syndrome presents due to a heterozygous loss-of-function mutation in the LIM homeobox transcription factor 1 beta gene, LMX1B, on chromosome 9q34.1 LMX1B gene mutations are fully penetrant, but there is variable expressivity, even within families.2
Case Report
A 69-year-old man presented to the dermatology clinic for a routine skin cancer screening. The patient’s history was remarkable for dystrophic fingernails and toenails since birth. In his 20s he developed progressively worsening instability of the left knee and chronic back pain due to scoliosis, lumbar lordosis, and spinal disc herniation. Since then, he underwent knee surgery and 7 back surgeries for rheumatologic disease. His medical history also was remarkable for osteoporosis, hypertension, and glaucoma. Family history was notable for similar findings in the patient’s sister; mother; and maternal aunt, uncle, and grandmother, all with varying disease severity.
Physical examination was remarkable for bilateral fingernail hypoplasia that was most prominent on the thumb, with improvement in each nail on progression toward the fifth digit (Figure 1A). Triangular fingernail lunulae, longitudinal ridging, and nail splitting were present (Figure 1A and 1B). Hypoplastic crumbly toenails also were appreciated (Figure 1C). Skin creases over the distal interphalangeal joints of the fingers and toes were conspicuously absent. Limited range of motion was noted in multiple joints, with profound limitation of bilateral elbow extension. Review of prior imaging reports revealed bilateral iliac horns as well as left patellar absence and right patellar hypoplasia (Figure 2). Urinalysis was remarkable for proteinuria and microscopic hematuria. Given the constellation of examination findings and positive family history, a diagnosis of NPS was made.
Comment
Nail-patella syndrome is characterized by variable dermatologic, neurologic, nephrogenic, ophthalmologic, and orthopedic clinical manifestations.3 Almost all patients with NPS have bilateral and symmetric nail changes, including absent or hypoplastic nails with ridging, splitting, or discoloration and triangular-shaped lunulae.1,4 Nail findings are the most consistent findings of NPS, as they are present in more than 98% of patients.5 The thumb often is the most severely affected nail, with improvement appreciated on progression toward the fifth digit, as seen in our patient (Figure 1A).5 Each individual nail usually is more severely affected on its ulnar side. When toenails are involved, the abnormalities tend to be less severe, and the little toenail is most commonly affected. Distal digital changes also are observed in almost all patients. Loss of dorsal creases in the skin overlying the distal interphalangeal joints can be considered as a diagnostic clue.3,4
There are a variety of orthopedic manifestations of NPS. Hypoplastic or absent patellae leading to recurrent subluxations or dislocations is a common finding.4 Bilateral symmetric bone formations (horns) arising from the iliac crest are pathognomonic but only found on radiography 70% of the time.6 Occasionally these protuberances can be palpated on physical examination,5 though this finding was not appreciated in our patient. Dysplasia of the elbows may result in limited elbow extension and limited pronation and supination. Early degenerative arthritis, lumbar lordosis, and scoliosis also are not uncommon. In addition, skeletal integrity is compromised, leading to early osteoporosis and increased risk for fractures.5
Nephropathy develops in approximately 30% to 40% of patients and is a major determinant of mortality in these patients.2 Mutations in the LMX1B gene lead to abnormal development of podocytes and reduction in collagen in the glomerular basement membrane. The first sign of renal involvement usually is proteinuria, with or without microscopic hematuria. As in our patient, many patients develop hypertension. Patients may progress to develop nephrotic syndrome and end-stage renal failure (5%–10%).7 Death from NPS-related nephropathy has occurred, even in childhood.4,5
Primary open-angle glaucoma has been recognized as a feature of NPS.8 It is the most frequent ocular abnormality observed, followed by ocular hypertension and Lester sign of the iris.3,5 These conditions also are more common in younger patients with NPS than in the general population.5 Important neurologic findings include epilepsy, peripheral neuropathy, attention deficit disorder, major depressive disorder, and vasomotor problems.9
Our case highlights the importance of recognizing this rare condition to provide a multidisciplinary approach to care that addresses all aspects of LMX1B-associated disease in affected individuals. Nail findings may be the first clue to the need for additional screenings in these patients. Nail-patella syndrome patients should undergo thorough ophthalmologic examinations every 2 years, including measurement of intraocular pressure, examination of the optic disc, and assessment of visual fields. Given the variability in severity of joint problems and the unpredictable anatomy of the joints, magnetic resonance imaging of the joints is recommended prior to orthopedic intervention. Most importantly, physicians should recognize this genodermatosis to implement periodic screenings for renal disease, as up to 40% of NPS patients develop kidney failure. Annual blood pressure measurements, urinalysis, and measurement of the protein to creatinine ratio in the urine are recommended. For patients with end-stage renal failure, renal transplantation results in cure of nephropathy and may even result in nail regrowth.10 Further, this case is notable in that it describes a patient with NPS who is older than most other individuals presenting with the condition, thereby revealing novel information about NPS in its more advanced stages.

Practice Points
- Nail-patella syndrome (NPS) is a multisystem disease.
- Nail findings (eg, triangular lunulae) may be the first clue to NPS and should prompt investigation of associated renal, ocular, neurologic, skeletal, and orthopedic abnormalities.
- Early intervention and a multidisciplinary approach to care can improve morbidity and mortality in patients with NPS.
Maximizing topical toenail fungus therapy
KAUAI, HAWAII – Two keys to effective topical treatment of onychomycosis are treat it early and address coexisting tinea pedis, according to Theodore Rosen, MD.
A third element in achieving treatment success is to use one of the newer topical agents: efinaconazole (Jublia) or tavaborole (Kerydin). The efficacy of efinaconazole approaches that of terbinafine, the most effective and widely prescribed oral agent, which has a 59% rate of almost complete cure, defined as less than 10% residual abnormal nail with no requirement for mycologic cure.
And while tavaborole isn’t quite as effective, it’s definitely better than previous topical agents, Dr. Rosen said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.
Both of these topicals are well tolerated and feature good nail permeation. They also allow for spread to the lateral nail folds and hyponychium. They even penetrate nail polish, although efinaconazole often causes the polish to lose its spiffy gloss, said Dr. Rosen, professor of dermatology at Baylor College of Medicine, Houston.
To underscore the importance of early treatment and addressing concomitant tinea pedis, he cited published secondary analyses of two identical double-blind, multicenter, 48-week clinical trials totaling 1,655 adults with onychomycosis who were randomized 3:1 to once-daily efinaconazole 10% topical solution or its vehicle.
Treat early
Phoebe Rich, MD, of the Oregon Dermatology and Research Center, Portland, broke down the outcomes according to disease duration, in a study of more than 1,500 patients with onychomycosis. She found that the complete cure rate at 52 weeks dropped off markedly in patients with a history of onychomycosis for 1 year or longer at baseline.
Complete cure – defined as no clinical involvement of the target toenail along with both a negative potassium hydroxide examination and a negative fungal culture at 52 weeks – was achieved in 43% of efinaconazole-treated patients with onychomycosis for less than 1 year. The rate then plunged to 17% in those with a disease duration of 1-5 years and 16% in patients with onychomycosis for more than 5 years. Nevertheless, the topical antifungal was significantly more effective than was the vehicle, across the board, with complete cure rates in the vehicle group of roughly 18%, 5%, and 2%, respectively, in patients with onychomycosis for less than 1 year, 1-5 years, and more than 5 years (J Drugs Dermatol. 2015 Jan;14[1]:58-62).
Tackle coexisting tinea pedis
Podiatrists analyzed the combined efinaconazole outcome data based on whether participants had no coexisting tinea pedis, baseline tinea pedis treated concomitantly with an investigator-approved topical antifungal, or tinea pedis left untreated. They concluded that treatment of coexisting tinea pedis decisively enhanced the efficacy of efinaconazole for onychomycosis.
A total of 21% of study participants had concomitant tinea pedis, and 61% of them were treated for it. At week 52, the onychomycosis complete cure rate was 29% in the efinaconazole group concurrently treated for tinea pedis, compared with just 16% if their tinea pedis was untreated (J Am Podiatr Med Assoc. 2015 Sep;105[5]:407-11).
“If you see tinea pedis, don’t blow it off. Treat it. Otherwise, you’re not getting rid of the fungal reservoir,” Dr. Rosen emphasized.
He noted that two topical agents approved for tinea pedis – naftifine 2% cream or gel and luliconazole 1% cream – are effective as once-daily therapy for 2 weeks, a considerably briefer regimen than with other approved topicals. And short-course therapy spells improved adherence, he added.
In the pivotal trials, naftifine had an effective treatment rate – a clinically useful endpoint defined as a small amount of residual scaling and/or redness but no itching – of 57%, while for luliconazole the rates were 33%-48%.
These two agents also are approved for treatment of tinea corporis and tinea cruris. Naftifine is approved as a once-daily treatment for 2 weeks, while luliconazole is, notably, a 7-day treatment. Luliconazole, in particular, is a relatively expensive drug, Dr. Rosen added, so insurers may require prior failure on clotrimazole.
When to treat onychomycosis topically
The pivotal trials of tavaborole and efinaconazole were conducted in patients with 20%-60% nail involvement. The infection didn’t extend to the matrix, and nail thickness and crumbly subungual debris were modest at baseline.
“There are always potential safety issues – drug interactions, GI disturbance, taste loss, headache, teratogenicity, cardiotoxicity, hepatotoxicity – anytime you put a pill in your mouth. So if you have a patient who’s dedicated enough to use a topical for 48 weeks and it’s a modestly affected nail, think about it,” Dr. Rosen advised.

KAUAI, HAWAII – Two keys to effective topical treatment of onychomycosis are treat it early and address coexisting tinea pedis, according to Theodore Rosen, MD.
A third element in achieving treatment success is to use one of the newer topical agents: efinaconazole (Jublia) or tavaborole (Kerydin). The efficacy of efinaconazole approaches that of terbinafine, the most effective and widely prescribed oral agent, which has a 59% rate of almost complete cure, defined as less than 10% residual abnormal nail with no requirement for mycologic cure.
And while tavaborole isn’t quite as effective, it’s definitely better than previous topical agents, Dr. Rosen said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.
Both of these topicals are well tolerated and feature good nail permeation. They also allow for spread to the lateral nail folds and hyponychium. They even penetrate nail polish, although efinaconazole often causes the polish to lose its spiffy gloss, said Dr. Rosen, professor of dermatology at Baylor College of Medicine, Houston.
To underscore the importance of early treatment and addressing concomitant tinea pedis, he cited published secondary analyses of two identical double-blind, multicenter, 48-week clinical trials totaling 1,655 adults with onychomycosis who were randomized 3:1 to once-daily efinaconazole 10% topical solution or its vehicle.
Treat early
Phoebe Rich, MD, of the Oregon Dermatology and Research Center, Portland, broke down the outcomes according to disease duration, in a study of more than 1,500 patients with onychomycosis. She found that the complete cure rate at 52 weeks dropped off markedly in patients with a history of onychomycosis for 1 year or longer at baseline.
Complete cure – defined as no clinical involvement of the target toenail along with both a negative potassium hydroxide examination and a negative fungal culture at 52 weeks – was achieved in 43% of efinaconazole-treated patients with onychomycosis for less than 1 year. The rate then plunged to 17% in those with a disease duration of 1-5 years and 16% in patients with onychomycosis for more than 5 years. Nevertheless, the topical antifungal was significantly more effective than was the vehicle, across the board, with complete cure rates in the vehicle group of roughly 18%, 5%, and 2%, respectively, in patients with onychomycosis for less than 1 year, 1-5 years, and more than 5 years (J Drugs Dermatol. 2015 Jan;14[1]:58-62).
Tackle coexisting tinea pedis
Podiatrists analyzed the combined efinaconazole outcome data based on whether participants had no coexisting tinea pedis, baseline tinea pedis treated concomitantly with an investigator-approved topical antifungal, or tinea pedis left untreated. They concluded that treatment of coexisting tinea pedis decisively enhanced the efficacy of efinaconazole for onychomycosis.
A total of 21% of study participants had concomitant tinea pedis, and 61% of them were treated for it. At week 52, the onychomycosis complete cure rate was 29% in the efinaconazole group concurrently treated for tinea pedis, compared with just 16% if their tinea pedis was untreated (J Am Podiatr Med Assoc. 2015 Sep;105[5]:407-11).
“If you see tinea pedis, don’t blow it off. Treat it. Otherwise, you’re not getting rid of the fungal reservoir,” Dr. Rosen emphasized.
