Phototherapy remains a viable element of psoriasis care for many patients, used alone or in conjunction with other treatments, according to updated guidelines issued jointly by the American Academy of Dermatology and the National Psoriasis Foundation.

“Phototherapy serves as a reasonable and effective treatment option for patients requiring more than topical medications and/or those wishing to avoid systemic medications or simply seeking an adjunct to a failing regimen,” wrote working group cochair Craig A. Elmets, MD, professor of dermatology at the University of Alabama at Birmingham, and coauthors.

The guidelines, which focus on phototherapy for adults with psoriasis, join a multipart series on psoriasis being published this year in the Journal of the American Academy of Dermatology.

The working group used an evidence-based model to examine efficacy, effectiveness, and adverse effects of the following modalities: narrow-band ultraviolet B (NB-UVB); broadband ultraviolet B (BB-UVB); targeted phototherapy using excimer laser and excimer lamp; psoralen plus ultraviolet A (PUVA) therapy, including topical, oral, and bath PUVA; photodynamic therapy (PDT), grenz ray therapy, climatotherapy; visible light therapy; Goeckerman therapy; and pulsed dye laser/intense pulsed light.

NB-UVB, which can be used to treat generalized plaque psoriasis, refers to wavelengths of 311-313 nm. The recommended treatment is two or three times a week, with a starting dose based on skin phenotype or minimal erythema dose. Although oral PUVA has shown higher clearance rates, compared with NB-UVB, NB-UVB has demonstrated fewer side effects. NB-UVB also has shown effectiveness for psoriasis in combination with medications including oral retinoids, “particularly useful in patients at increased risk for skin cancer,” the working group wrote. Genital shielding and eye protection are recommended during all phototherapy sessions to reduce the risk of cancer and cataracts, they emphasized.

BB-UVB, an older version of NB-UVB, is still effective for generalized plaque psoriasis as monotherapy, but evidence does not support additional benefit in combination with other treatments, and overall BB-UVB is less effective than either NB-UVB or oral PUVA, the working group said.

For treatment of localized psoriatic lesions, some evidence supports the ability of targeted UVB therapy to improve lesions in fewer treatments and at a lower cumulative dose, compared with nontargeted phototherapy, for palmoplantar plaque psoriasis and palmoplantar pustulosis. Excimer lasers also have shown effectiveness against scalp psoriasis, the working group noted. However, “there is insufficient evidence to recommend the excimer laser rather than topical PUVA for treatment of localized plaque psoriasis,” they said.

PUVA treatments are available as topical creams, or they can be taken orally, or mixed with bath water. All forms of PUVA include psoralens, photosensitizing agents that prepare target cells for the effects of UVA light. Topical PUVA has demonstrated particular effectiveness for palmoplantar psoriasis, the working group noted, but there is a risk of phototoxicity, so it has become less popular, they added. Similarly, evidence supports effectiveness of oral and bath PUVA, but all forms are used less frequently because of the increased availability of NB-UVB phototherapy, they said.

PDT is primarily used to destroy premalignant or malignant cells, and in theory “PDT-induced apoptosis of T lymphocytes could lead to reductions in inflammatory cytokines and, in turn, to improvement of psoriasis,” the working group noted. However, “clinical studies have failed to find significant benefit” of PDT using either 5-aminolevulinic acid (ALA) or methyl aminolevulinic acid (MAL) for psoriasis, or any significant benefits of MAL-PDT for nail psoriasis.

The grenz ray is an effective, but rarely used treatment in which 75% of long-wavelength ionizing radiation is absorbed by the first 1 mm of skin and 95% is absorbed within the first 3 mm of skin to protect the deeper tissues from radiation. Although more alternatives are available, grenz rays can be used for psoriasis patients unable to tolerate UV therapy, according to the working group.

Climatotherapy involves temporary or permanent relocation of the patient to a part of the world with a climate that could be favorable for psoriasis because of the unique effects of environmental factors in those areas. The evidence to support climatotherapy is both subjective and objective, but considered safe.

Visible light has been associated with improvement in erythema in psoriasis, with hyperpigmentation as the only notable side effect based on the evidence reviewed. However, the working group found the current evidence insufficient to recommend the use of intense pulsed light for treating psoriasis.

Goeckerman therapy, a method that combines coal tar and UVB phototherapy, has shown safety and effectiveness for patients with recalcitrant or severe psoriasis, and remains a recommended treatment, according to the working group research. However, this method is underused, especially in the United States, because of the messiness of the application, challenge of insurance reimbursement, and investment of time for outpatient care, the work group noted.

Pulsed dye laser treatment is effective for nail psoriasis, and reported adverse effects have been mild, according to the working group.

Overall, the guidelines emphasize that quality of life and disease severity should be considered and discussed with patients along with efficacy and safety information so they can make informed decisions about adding phototherapy to a current regimen or switching among modalities.

The guidelines have no funding sources. Several coauthors disclosed relationships with multiple companies, including manufacturers of psoriasis products; however, a minimum of 51% of the work group had no relevant financial conflicts to disclose, in accordance with AAD policy. Work group members with potential conflicts recused themselves from discussion and drafting of recommendations in the relevant topic areas. Alan Menter, MD, chairman of the division of dermatology, Baylor University Medical Center, Dallas, is the other cochair of the work group.

To the Editor:

Erlotinib is a small-molecule selective tyrosine kinase inhibitor that functions by blocking the intracellular portion of the epidermal growth factor receptor (EGFR)^1,2; EGFR normally is expressed in the basal layer of the epidermis, sweat glands, and hair follicles, and is overexpressed in some cancers.^1,3 Normal activation of EGFR leads to signal transduction through the mitogen-activated protein kinase (MAPK) signaling pathway, which stimulates cell survival and proliferation.^4,5 Erlotinib-induced inhibition of EGFR prevents tyrosine kinase phosphorylation and aims to decrease cell proliferation in these tumors.

Erlotinib is indicated as once-daily oral monotherapy for the treatment of advanced-stage non–small cell lung cancer (NSCLCA) and in combination with gemcitabine for treatment of advanced-stage pancreatic cancer.¹ A number of cutaneous side effects have been reported, including acneform eruption, xerosis, paronychia, and pruritus.⁶ Other tyrosine kinase inhibitors, which also decrease signal transduction through the MAPK pathway, have some overlapping side effects; among these are vemurafenib, a selective BRAF inhibitor, and sorafenib, a multikinase inhibitor.^7,8

A 70-year-old man with NSCLCA presented with eruptive nevi and darkening of existing nevi 3 months after starting monotherapy with erlotinib. Physical examination demonstrated the simultaneous appearance of scattered acneform papules and pustules; diffuse xerosis; and numerous dark brown to black nevi on the trunk, arms, and legs. Compared to prior clinical photographs taken in our office, darkening of existing medium brown nevi was noted, and new nevi developed in areas where no prior nevi had been visible (Figure 1).

A review of the patient’s treatment timeline revealed that all other chemotherapeutic medications had been discontinued a minimum of 5 weeks before starting erlotinib. A complete cutaneous examination performed in our office after completion of these chemotherapeutic agents and prior to initiation of erlotinib was unremarkable for abnormally dark or eruptive nevi.

Since starting erlotinib treatment, the patient underwent 10 biopsies of clinically suspicious dark nevi performed by a dermatologist in our office. Two of these were diagnosed as melanoma in situ and one as an atypical nevus. A temporal association of the darkening and eruptive nevi with erlotinib treatment was established; however, because erlotinib was essential to his NSCLCA treatment, he continued erlotinib with frequent complete cutaneous examinations.

A number of cutaneous side effects have been described during treatment with erlotinib, the most common being acneform eruption.⁶ The incidence and severity of acneform eruptions have been positively correlated to survival in patients with NSCLCA.^3,5,6 Other common side effects include xerosis, paronychia, and pruritus.^1,5,6 Less common side effects include periungual pyogenic granulomas and hair growth abnormalities.¹

Eruptive nevi previously were reported in a patient who was treated with erlotinib.¹ Other tyrosine kinase inhibitors that also decrease signal transduction through the MAPK pathway, including sorafenib and vemurafenib, have been reported to cause eruptive nevi. There are 7 reports of eruptive nevi with sorafenib and 5 reports with vemurafenib.^7-9 Development of nevi were noted within a few months of initiating treatment with these medications.⁷

A PubMed search of articles indexed for MEDLINE using the terms erlotinib and melanoma and erlotinib and nevi yielded no prior reports of darkening of existing nevi or the development of melanoma during treatment with erlotinib. However, vemurafenib has been reported to cause dysplastic nevi, melanomas, and darkening of existing nevi, in addition to eruptive nevi.^8-10 The side effects of vemurafenib have been ascribed to a paradoxical upregulation of MAPK in BRAF wild-type cells. This effect has been well documented and demonstrated in vivo.^8,10 Perhaps erlotinib has a similar potential to paradoxically upregulate the MAPK pathway, thus stimulating cellular proliferation and survival.

Another tyrosine kinase receptor, c-KIT, is found on the cell membrane of melanocytes along with EGFR.^11,12 The c-KIT receptor also activates the MAPK pathway and is critical to the development, migration, and survival of melanocytes.^11,13 Stimulation of the c-KIT tyrosine kinase receptor also can induce melanocyte proliferation and melanogenesis.¹¹ The c-KIT receptor is encoded by the KIT gene (KIT proto-oncogene receptor tyrosine kinase). Mutations in this gene are associated with melanocytic disorders. Inherited KIT mutation leading to c-KIT receptor deficiency is associated with piebaldism. Acquired activating KIT mutations increasing c-KIT expression are associated with acral and mucosal melanomas as well as melanomas in chronically sun-damaged skin.¹³

We hypothesized that erlotinib-induced inhibition of the MAPK pathway could lead to a reactive increase in expression of c-KIT and thus stimulate melanocyte proliferation and pigment production. Similar feedback upregulation of an MAPK pathway stimulating receptor during downstream MAPK inhibition has been demonstrated in colon adenocarcinoma; in this setting, BRAF inhibitors blocking the MAPK pathway leads to upregulation of EGFR.­¹⁴ In our patient, c-KIT immunostaining revealed a mild to moderate increase in intensity (ie, the darkness of the staining) in nevi and melanomas during treatment with erlotinib compared to nevi biopsied before erlotinib treatment (Figure 2). The increased intensity of c-KIT immunostaining was further confirmed via semiquantitative digital image analysis. Using this method, a darkened nevus biopsied during treatment with erlotinib demonstrated 43.16% of cells (N=31,451) had very strong c-KIT staining, while a nevus biopsied before treatment with erlotinib demonstrated only 3.32% of cells (N=7507) with very strong c-KIT staining. Increased expression of c-KIT, possibly reactive to downstream inhibition the MAPK pathway from erlotinib, could be implicated in our case of eruptive nevi.

ORLANDO – Thyroid disorders can have significant effects on the heart and the cardiovascular system, Christine Kessler, MN, ANP-C, CNS, BC-ADM, FAANP, said at the Cardiovascular & Respiratory Summit by Global Academy for Medical Education.

Even subclinical hypothyroidism “can be really impactful,” said Ms. Kessler, the founder of Metabolic Medicine Associates in King George, Va.

Thyroid function should be evaluated in patients with a fast resting heart fate, new-onset atrial fibrillation (AFib), idiopathic heart failure, bradycardia, using amiodarone, resistant hypertension, pericardial effusion, and statin-resistant hyperlipidemia, said Ms. Kessler, who also is a nurse practitioner and researcher. Other patients who should be evaluated: those older than 60 years, with a family history of autoimmune disease, fertility issues, new-onset anxiety/depression, and patients with high-risk pregnancy. Hypothyroidism may have more impact on cardiac health than does hyperthyroidism.

Levels of thyroid-stimulating hormone (TSH), triiodothyronine (T₃), and free thyroxine (FT₄) are typically used to evaluate thyroid function. High TSH levels are usually indicative of hypothyroidism if FT₄ and T₃ are low; hyperthyroidism is likely the diagnosis if TSH is low while FT₄ and T₃ are high. Subclinical hypothyroidism is characterized by high TSH and normal FT₄ and T₃ levels; subclinical hyperthyroidism is associated with low TSH with normal FT₄ and T₃ levels.*

Hypothyroidism can cause increased diastolic hypertension and systemic vascular resistance, elevated levels of C-reactive protein (CRP) and homocysteine, decreased myocardial contractility, decreased cardiac output, reduced heart rate, and liver function abnormalities. Most commonly, it is caused by the autoimmune disease Hashimoto’s hypothyroidism but also can result from radiation, thyroidectomy, nontoxic multinodular goiter, and drugs with antithyroid activity such as birth control medications that contain estrogen. Hypothyroidism also raises the risk of coronary artery disease through lipid aberrations such as increased LDL level and decreased number of LDL cholesterol receptors. Myocardial contractility from hypothyroidism also increases the risk of mortality in patients with heart disease and heart failure. Clinicians also should take special precautions with narcotics and anesthesia when caring for patients with hypothyroidism because of the risk of bradycardia, Ms. Kessler said.

In subclinical hypothyroidism, clinicians should treat with half the recommended dose of levothyroxine in patients aged 45-65 years and who have high levels of lipids and CRP. “At the age of 70, I don’t worry if you’re subclinical unless [the patient is] profoundly, profoundly symptomatic,” she said. In overt hypotension, the main concern is an increased risk of ischemic heart disease that can result from overtreatment, and these patients usually are started on a low dose of levothyroxine with escalated doses until the patient achieves a euthyroid state.

Hyperthyroidism is most commonly caused by Grave’s disease, with 85% of those affected younger than age 40 years. Other causes include toxic multinodular goiter, toxic adenoma, TSH-producing pituitary adenomas, resistance to thyroid hormone, thyroiditis, excessive ingestion of iodine, shrinking of the thyroid gland, and a human chorionic gonadotropin–producing tumor such as struma ovarii. Common cardiac complications of hyperthyroidism are increased heart rate and blood pressure, reduced systemic vascular resistance, and increased cardiovascular disease and mortality in addition to increased cardiac hypertrophy, pulmonary hypertension, and heart failure. Heart rhythm, atrial fibrillation, atrial flutter, increased sinus tachycardia, and increased angina are all possible complications of hyperthyroidism.

Treatment priorities for hyperthyroidism are the immediately relieving any symptoms, reducing thyroid hormone production, and blocking the conversion of T₄ to T₃. For symptomatic patients, beta-blockers will help relieve symptoms and block the T4/T₃ conversion. Follow-up treatment should include antithyroid drugs such as methimazole or propylthiouracil.

Patients who have subclinical hyperthyroidism are usually asymptomatic and may not always require treatment.

“In subclinical hypothyroidism, keep your mitts off the older patients. They’re usually going to do better, and you don’t want to throw them into hyperthyroidism,” she said. “If they’re [experiencing] subclinical hyperthyroidism, you’re going to treat them, because if not, they’re going to go into AFib, cardiovascular death, [and] they’re going to have osteoporosis. It’s not a good thing.”

Ms. Kessler reports being on the speakers bureau and an adviser for Novo Nordisk on obesity, and an adviser for them on type 2 diabetes, as well. She also reports being the study chairperson for the Florajen Patient Trial Program. The Cardiovascular & Respiratory Summit is part of Global Academy for Medical Education.

A 34-year-old woman with a history of adamantinoma of the right tibia that had been surgically resected with tibial reconstruction 5 years prior presented with a mildly tender, enlarging lesion on the right distal shin of 6 months’ duration that had started to change color. Review of systems was otherwise negative. Physical examination revealed an 8-mm, slightly tender, rubbery, pink papule adjacent to the surgical scar over the right tibia (Figure 1). Given the rapid growth of the lesion and its proximity to the surgical site, a punch biopsy was performed.

Histopathologic examination demonstrated a densely cellular dermal tumor composed of spindle cells with large hyperchromatic nuclei, numerous mitotic figures, and minimal eosinophilic cytoplasm (Figure 2A). Immunohistochemical studies revealed that approximately 40% of the tumor nuclei were immunoreactive to Ki-67 (Figure 2B), and total cytokeratin was focally positive (Figure 2C). A diagnosis of metastatic adamantinoma was made. Positron emission tomography and magnetic resonance imaging revealed new lytic lesions involving the T10 and L2 vertebrae (without frank spinal cord compression) and the right superior sacrum. Additionally, a small pulmonary nodule on the left upper lobe was noted on positron emission tomography, but it was below the size threshold for reliable detection. A computed tomography–guided biopsy of the T10 lesion demonstrated metastatic adamantinoma. The patient underwent a spinal stabilization procedure and discussed options regarding further oncologic and palliative management.

Adamantinomas are slow growing, and as a result, patients often present with gradual onset of pain and swelling that persists for years.^3,4 Metastasis occurs in 10% to 30% of patients, typically located in regional lymph nodes, the lungs, and distant bone.^1,4 Our case represents a rare instance of adamantinoma metastasis to the skin. Although primary adamantinomas consist of both epithelial and stromal components, the typical metastatic lesions of adamantinomas are solely epithelial (often in a spindle-cell pattern),¹ as was seen in our patient.

Operative removal via amputation or en bloc resection with limb salvage is the current treatment of choice. Adamantinomas are highly radioresistant, and chemotherapy has shown minimal efficacy.^3,5

In conclusion, the presence of cutaneous metastasis from an adamantinoma is rare. Our case emphasizes this tumor’s potential for late metastasis as well as late recurrence.^3,6 Most importantly, dermatologists should be made aware of this rare bone tumor and its unusual presentation, as early detection can aid in prognosis.

In what is becoming an annual tradition, the Mayo Clinic came out on top of the U.S. News & World Report 2019-2020 Best Hospitals ranking.

The Rochester, Minn., hospital has now been No. 1 on the U.S. News Honor Roll for 4 consecutive years. The last institution to head the list before that streak, Massachusetts General Hospital in Boston, was second this year, followed by Johns Hopkins Hospital in Baltimore, the Cleveland Clinic, and New York-Presbyterian Hospital–Columbia and Cornell in New York, U.S. News reported July 30.

The Mayo Clinic finished first in five of the 16 specialties used in the evaluation process – diabetes and endocrinology; ear, nose, and throat; gastroenterology and GI surgery; urology; and nephrology – and had a total of 13 top-five rankings. Massachusetts General had one first place in psychiatry and six total top fives, while Johns Hopkins, despite its lower overall ranking, had three top rankings – geriatrics, neurology and neurosurgery, and rheumatology – and nine top fives, the U.S. News data show.


This year’s 30th edition of the rankings involved 4,653 community inpatient hospitals, of which 1,447 received a “High Performing” rating in at least one of the nine procedures and conditions assessed and 165 were nationally ranked (top 50) in at least one of the 16 specialties. Twelve specialties are ranked largely on objective data, with the three most recent years of an annual expert opinion survey of specialized physicians also factored in. The other four specialties are ranked based entirely on the survey of expert opinion.

The research organization RTI International conducted the physician survey and produced the Best Hospitals methodology and national rankings under contract with U.S. News.

The Food and Drug Administration has accepted the new drug application for dasotraline for the treatment of moderate to severe binge-eating disorder, the drug’s developer, Sunovion, announced July 30.

Dasotraline, a dopamine and norepinephrine reuptake inhibitor, demonstrated significant efficacy in a pair of 12-week, randomized, placebo-controlled studies (SEP360-221 and SEP360-321). The drug also was found to be well tolerated by patients with binge-eating disorder (BED), both in those studies and in a long-term safety study that followed patients for up to a year (SEP360-322).

The medication – characterized by an extended half-life – is to be taken once a day. The most common adverse events reported by patients who took dasotraline include insomnia, dry mouth, decreased appetite, anxiety, nausea, and decreased weight.

BED is more common than any other eating disorder, with an estimated lifetime prevalence among U.S. adults of 1.25% for women and 0.42% for men (CNS Spectr. 2019 Jun 14. doi: 10.1017/S109285291900103). The condition also might run in families. BED often is comorbid with other psychiatric and behavioral disorders, such as depression, substance use, and PTSD, noted Antony Loebel, MD, president and CEO of Sunovion, in a press release. He also said BED often is underrecognized and undertreated.

Meta-analytic reviews show that cognitive-behavioral therapy is considered first-line treatment for BED. However, limited access to such psychological treatments makes the development of medication options such as dasotraline important.

Last year, the agency rejected a new drug application for dasotraline for the treatment of ADHD, citing a need for additional data. The action date by the FDA on dasotraline for BED is May 14, 2020, Sunovion reported.

NEW YORK – Flaking, itchy, swollen lips represent more than a cosmetic problem. Eczematous cheilitis can interfere with communication and nutrition, but patients may be slow to seek help, Bethanee Schlosser, MD, PhD, said at the American Academy of Dermatology summer meeting.

One of the challenges in helping patients with lip problems is that lips are constantly in motion and constantly interacting with the outside world, said Dr. Schlosser, of the department of dermatology, Northwestern University, Chicago. There’s ongoing low-level trauma with phonation, eating, drinking, and general environmental exposure, she said. Eczematous cheilitis will present with scaling and erythema of the vermilion lips, with lower lip involvement often more pronounced than symptoms on the upper lip. Fissuring and erosion are sometimes, but not always, present as well.

In addition to flaking and redness, Dr. Schlosser noted that patients will complain of dry lips, irritation, itching, and sometimes tingling.

Sorting out the etiology of eczematous cheilitis requires a thorough history. “Ask about habits, such as lip licking, picking, or biting,” she said. Recent dental work, braces, or other appliances for alignment or temporomandibular joint problems can introduce both mechanical irritation and potential allergens, and even musical instruments can be culprits, such as when an oboe reed causes an allergic reaction.

Personal hygiene products, cosmetics, gum chewing, and candy consumption can be the irritant culprits, noted Dr. Schlosser. Careful questioning of patients and examination of the products used can provide clues, since dyes and pigments in cosmetics and gum may provoke reactions.

History taking should also include questions about tobacco in all forms, marijuana, and prescription medication, which can cause lip problems. And it’s important to ask about skin disease in general, to determine if symptoms are present in other anatomic locations, and to ask about any family history of skin disease, she said.

Endogenous contributors can include true atopic dermatitis, psoriasis, and nutritional deficiencies. Psoriatic cheilitis can have prominent crusting and exfoliation. In a Brazilian study that evaluated patents with cutaneous psoriasis and age-, race-, and sex-matched controls with no history of skin disease, psoriasis was associated with geographic tongue, with an odds ratio of 5.0 (95% CI 1.5-16.8). Geographic stomatitis can also be seen, said Dr. Schlosser. Tongue fissures were also more common among those with psoriasis cheilitis (OR 2.7, 95% confidence interval, 1.3-5.6) in the same study (Med Oral Patol Oral Cir Bucal. 2009 Aug 1;14[8]:e371-5).

For psoriatic cheilitis, looking beyond the lips can help refine the diagnosis, she noted. There may be intra-oral signs or signs of extra-oral involvement, especially on the scalp, ears, and genitalia. Koebnerization may be difficult to detect on the lips, but may be present elsewhere. A family history of psoriasis may also tip the scales toward this diagnosis.

Exogenous causes of eczematous cheilitis are much more common and can include contact with irritants and allergens, factitial cheilitis, and cheilitis medicamentosa, Dr Schlosser pointed out.

Allergic contact dermatitis can come from local exposure (to cosmetics and other personal care items, for example) or from incidental exposures. Components of saliva can become concentrated when saliva dries outside the oral cavity, so for chronic lip lickers, saliva alone can be sufficiently irritating to provoke a cheilitis, Dr. Schlosser said.

Transfer of an irritant or allergen is also possible from other body sites, as when a nail-chewer develops allergic cheilitis from an ingredient in nail polish. Transfer from products used on other facial areas and the hair is also possible, as is “connubial transfer,” when an allergen is transferred from an intimate partner.

Cutaneous patch tests can be helpful in pinpointing the offending agent, or agents, according to Dr. Schlosser. She cited a study of 91 patients (77% of whom were female) who underwent patch testing for eczematous cheilitis. The researchers determined that 45% of patients had allergic contact cheilitis (Int J Dermatol. 2016 Jul;55[7]:e386-91).

The patch testing revealed that fragrances, balsam of Peru (Myroxylon pereirae resin), preservatives, and even metals such as nickel and gold were common allergens. The findings echo those in another database review that showed fragrances, M. pereirae, and nickel as the top three allergens on patch testing for lip cheilitis.

Dr. Schlosser said that the most common offending sources are lipsticks, makeup, other cosmetic products, and moisturizer, which are responsible for 10% or more of reactions.

Whatever the etiology, the treatment of eczematous cheilitis can be divided conceptually into two phases. During the induction phase, use of a low- to mid-potency topical corticosteroid ointment quiets inflammation. Examples include alclometasone 0.05%, desonide 0.05%, fluticasone 0.005%, or triamcinolone 0.1%. “Ointment formulations are preferred,” said Dr. Schlosser, since they won’t dissolve so easily with lip licking and will adhere well to the surface of the vermilion lip.

Next, a topical calcineurin inhibitor such as tacrolimus 0.1% can be used for maintenance. Other topical medications, especially topical anesthetics, should be used with caution, she said.

For psoriatic cheilitis, induction with 5% salicylic acid ointment can be followed by the topical calcineurin inhibitor phase, said Dr. Schlosser.

NEW YORK – Flaking, itchy, swollen lips represent more than a cosmetic problem. Eczematous cheilitis can interfere with communication and nutrition, but patients may be slow to seek help, Bethanee Schlosser, MD, PhD, said at the American Academy of Dermatology summer meeting.

One of the challenges in helping patients with lip problems is that lips are constantly in motion and constantly interacting with the outside world, said Dr. Schlosser, of the department of dermatology, Northwestern University, Chicago. There’s ongoing low-level trauma with phonation, eating, drinking, and general environmental exposure, she said. Eczematous cheilitis will present with scaling and erythema of the vermilion lips, with lower lip involvement often more pronounced than symptoms on the upper lip. Fissuring and erosion are sometimes, but not always, present as well.

In addition to flaking and redness, Dr. Schlosser noted that patients will complain of dry lips, irritation, itching, and sometimes tingling.

Sorting out the etiology of eczematous cheilitis requires a thorough history. “Ask about habits, such as lip licking, picking, or biting,” she said. Recent dental work, braces, or other appliances for alignment or temporomandibular joint problems can introduce both mechanical irritation and potential allergens, and even musical instruments can be culprits, such as when an oboe reed causes an allergic reaction.

Personal hygiene products, cosmetics, gum chewing, and candy consumption can be the irritant culprits, noted Dr. Schlosser. Careful questioning of patients and examination of the products used can provide clues, since dyes and pigments in cosmetics and gum may provoke reactions.

History taking should also include questions about tobacco in all forms, marijuana, and prescription medication, which can cause lip problems. And it’s important to ask about skin disease in general, to determine if symptoms are present in other anatomic locations, and to ask about any family history of skin disease, she said.

Endogenous contributors can include true atopic dermatitis, psoriasis, and nutritional deficiencies. Psoriatic cheilitis can have prominent crusting and exfoliation. In a Brazilian study that evaluated patents with cutaneous psoriasis and age-, race-, and sex-matched controls with no history of skin disease, psoriasis was associated with geographic tongue, with an odds ratio of 5.0 (95% CI 1.5-16.8).

NEW YORK – Nail discoloration, in all its variety, has a wide differential. And while that differential narrows when a patient presents with concerns about nails with red discoloration, there’s still a long list of diagnoses to consider.

During a nail-focused session at the American Academy of Dermatology summer meeting, Shari Lipner, MD, PhD, took attendees through a presentation-based approach that gets to the root etiology of erythronychia and guides diagnosis and treatment options. The first conceptual division is to differentiate localized longitudinal erythronychia from polydactylous longitudinal erythronychia.

“However, regardless of the etiology, erythronychia shares a common pathogenesis,” said Dr. Lipner, a dermatologist at New York–Presbyterian Hospital and Weil Cornell Medicine. The process begins in the distal nail matrix, resulting in a thin long strip of ventral nail becoming discolored, with the nail bed filling in the concavity. The engorged nail bed also makes the affected nail unit prone to splinter hemorrhages, and the thinned, transparent nail makes the erythema more visible, she explained.
 

Polydactylous longitudinal erythronychia

For erythronychia affecting several nails, onychotillomania is among the possible causes. This condition “often goes hand in hand with onychophagia,” and trichotillomania, skin-picking, or other self-mutilating disorders may also be present, she said. In both the adult and pediatric population, onychotillomania can accompany psychiatric disorders, including depression and obsessive-compulsive disorder, and may be associated with suicidal ideation, she added.

When onychotillomania is the cause, erythronychia may be accompanied by paronychia, and patients will often have a shortened nail bed and an atrophic nail plate. Dorsal pterygium may also be present.

Dermoscopy can provide some clues that onychotillomania is the culprit, said Dr. Lipner, citing a study that looked at dermoscopic images of 36 cases, which found scales in 94%, absence of the nail plate in 83%, and characteristic wavy lines in 69% (J Am Acad Dermatol. 2018 Oct;79[4]:702-5). Other frequent dermoscopy findings included hemorrhages (64%), crusts (61%), nail bed pigmentation (47%), and speckled dots (39%).

Lichen planus can also affect the nails, with erythronychia among its manifestations, she noted. Though lichen planus is thought of as a disease of middle or older age, usually affecting those aged 50-70 years, “15% of those affected are less than 20 years old,” she said.

The erythronychia of lichen planus is often accompanied by longitudinal riding, splitting, and atrophy of the nail plate, she said. Pterygium can also be present, representing a scar in the nail matrix. Dermatopathology will reveal a patchy, bandlike lichenoid infiltrate, with variable sawtooth hypergranulosis and hyperplasia.

“There’s not much evidence about how to treat lichen planus of the nails,” noted Dr. Lipner. Options can include intralesional corticosteroid injections at the nail matrix, topical corticosteroids, oral methotrexate, and retinoids.

Darier disease, an inherited condition caused by mutations in ATP2A2, has both skin and nail manifestations. Characteristic skin signs include hyperkeratotic papules, cobblestone papules, and palmar pits, she said. When nails are affected – as they are in up to 95% of Darier disease patients – they can have a characteristic “candy cane” appearance, with bands of longitudinal erythronychia alternating with normal-colored nail. The nails can also have V-shaped notching, she added.

Patients with systemic lupus erythematosus can also have longitudinal erythronychia; here, dermoscopy will show the characteristic prominent capillary loops in the proximal nail folds, she said.

Foreign substances such as nail polish and dyes, when they’re the source of erythronychia in one or several nails, can usually be wiped off with alcohol or acetone; also, “the proximal margin of discoloration will follow the same pattern as the nail fold,” said Dr. Lipner.

Localized longitudinal erythronychia

When the red discoloration is limited to a single nail, the differential shifts, said Dr. Lipner. With a hematoma, there’s often a history of trauma, and dermoscopy will show characteristic globules and streaks.

The first clue that erythronychia caused by onychopapilloma can be seen at the lunula: There will often be a comet- or pencil-shaped point to the discoloration in that region. But, she said, “the key is to do dermoscopy at the free edge of the nail plate. In 100 percent of cases, there will be a subungual hyperkeratotic papule” that will solidify the diagnosis.

Histopathology of onychopapillomas – a relatively recently recognized entity – will show nail bed and distal matrix acanthosis, with the distal nail bed showing matrix metaplasia, Dr. Lipner said.

Glomus tumors arise from cells of the glomus body, a specialized vascular apparatus that is involved in temperature regulation. “These structures are abundant in the digits and the subungual region,” said Dr. Lipner, which means that glomus tumors – a benign lesion – may develop subungually. Glomus tumors can be idiopathic, but she added, “think neurofibromatosis type 1 if you see multiple glomus tumors.”

Glomus tumors will present with longitudinal erythronychia, with a distal split of the nail sometimes accompanying the discoloration. A round bluish to gray nodule can also be seen. A thorough history and exam can help solidify the diagnosis, said Dr. Lipner; there’s a characteristic triad of point tenderness with the application of pressure to the nail, pain, and cold hypersensitivity.

Classically, the point tenderness is assessed by Love’s test, which elicits severe pain when the subungual tumor is pressed with a small object like the end of paper clip or a ballpoint pen. Application of a tourniquet to the arm after elevation, termed Hildreth’s test, should alleviate subungual glomus tumor pain, and release of the tourniquet causes an abrupt and marked recurrence of pain. Immersing the patient’s affected hand in cold water also increases glomus tumor pain.

“Imaging can be quite helpful” to confirm a glomus tumor diagnosis, said Dr. Lipner. “X-ray is cheap, and you can see erosions in 50% of patients.” However, she added, doppler ultrasound and magnetic resonance imaging are more sensitive, detecting tumors as small as 2 mm.

“Biopsy with histopathology is the gold standard in making the diagnosis” of glomus tumor, though, she noted. Pathologic examination will show monomorphic cells with small caliber vascular channels.

Malignancy is actually uncommon with erythronychia, though it’s always in the differential diagnosis, she said.

In one case series examining subungual squamous cell carcinomas, common findings included onycholysis and localized hyperkeratosis, along with longitudinal erythronychia. “This may be subtle; splinter hemorrhages can also be present,” noted Dr. Lipner, adding, “If there are any symptoms, or an evolving band, a biopsy is indicated.”

“Even with erythronychia, the presentation can be quite variable,” she said. Nail unit melanoma can count erythronychia among the presenting signs. Clues that should raise suspicion for melanoma can include a wide band and prominent onycholysis, especially distal onycholysis and splintering. Again, she said, “biopsy with histopathology is the gold standard in making the diagnosis”; any symptoms or evidence of an evolving band should trigger a biopsy.

Dr. Lipner had no conflicts of interest relevant to her presentation.

Histopathology of onychopapillomas – a relatively recently recognized entity – will show nail bed and distal matrix acanthosis, with the distal nail bed showing matrix metaplasia, Dr. Lipner said.

Glomus tumors arise from cells of the glomus body, a specialized vascular apparatus that is involved in temperature regulation. “These structures are abundant in the digits and the subungual region,” said Dr. Lipner, which means that glomus tumors – a benign lesion – may develop subungually. Glomus tumors can be idiopathic, but she added, “think neurofibromatosis type 1 if you see multiple glomus tumors.”

Glomus tumors will present with longitudinal erythronychia, with a distal split of the nail sometimes accompanying the discoloration. A round bluish to gray nodule can also be seen. A thorough history and exam can help solidify the diagnosis, said Dr. Lipner; there’s a characteristic triad of point tenderness with the application of pressure to the nail, pain, and cold hypersensitivity.

Classically, the point tenderness is assessed by Love’s test, which elicits severe pain when the subungual tumor is pressed with a small object like the end of paper clip or a ballpoint pen. Application of a tourniquet to the arm after elevation, termed Hildreth’s test, should alleviate subungual glomus tumor pain, and release of the tourniquet causes an abrupt and marked recurrence of pain. Immersing the patient’s affected hand in cold water also increases glomus tumor pain.

“Imaging can be quite helpful” to confirm a glomus tumor diagnosis, said Dr. Lipner. “X-ray is cheap, and you can see erosions in 50% of patients.” However, she added, doppler ultrasound and magnetic resonance imaging are more sensitive, detecting tumors as small as 2 mm.

“Biopsy with histopathology is the gold standard in making the diagnosis” of glomus tumor, though, she noted. Pathologic examination will show monomorphic cells with small caliber vascular channels.

Malignancy is actually uncommon with erythronychia, though it’s always in the differential diagnosis, she said.

In one case series examining subungual squamous cell carcinomas, common findings included onycholysis and localized hyperkeratosis, along with longitudinal erythronychia. “This may be subtle; splinter hemorrhages can also be present,” noted Dr. Lipner, adding, “If there are any symptoms, or an evolving band, a biopsy is indicated.”

“Even with erythronychia, the presentation can be quite variable,” she said. Nail unit melanoma can count erythronychia among the presenting signs. Clues that should raise suspicion for melanoma can include a wide band and prominent onycholysis, especially distal onycholysis and splintering. Again, she said, “biopsy with histopathology is the gold standard in making the diagnosis”; any symptoms or evidence of an evolving band should trigger a biopsy.

Dr. Lipner had no conflicts of interest relevant to her presentation.

U.S. regulators canceled a July 31, 2019, advisory committee about lumateperone, an experimental schizophrenia drug that has had some mixed results in testing.

On July 23, the Food and Drug Administration announced the cancellation of the Psychopharmacologic Drugs Advisory Committee meeting it had previously called for to review the new drug application for lumateperone. The agency said the meeting was canceled because of “new information regarding the application.” The FDA said it was continuing to evaluate the application and would, as needed, announce a future meeting on it.

The developer of lumateperone, Intra-Cellular Therapies, issued its own statement on July 23, noting that a meeting had been scheduled with the FDA “shortly” and that an update would be provided after the meeting. The New York–based firm also said it recently had provided additional information to the FDA to meet agency requests. This information was related to “nonclinical studies.”

“The FDA canceled the advisory committee meeting to allow sufficient time to review this new and any forthcoming information as they continue” to review the new drug application for lumateperone, Intra-Cellular said in the July 23 statement. The company also said there may be an extension of the FDA’s Sept. 27, 2019, target action date on the lumateperone application.

Investors viewed this as bad news. Shares of Intra-Cellular on July 23 dropped from an opening price of $11.90 to a closing one of $8.19. On July 29, they closed at $8.12.

Still, it is unclear how the FDA will decide on the lumateperone application and whether the agency will call another advisory committee meeting on it.

Last year, the FDA accepted the application for lumateperone, a once-daily treatment, Intra-Cellular said. The agency had in 2017 given a fast-track designation to lumateperone for the treatment of schizophrenia.


Lumateperone is the lead product for the company. Intra-Cellular describes lumateperone as having a novel mechanism of action, and is said to act on the serotonergic, dopaminergic, and glutamatergic systems.

On the company’s website, Intra-Cellular says three large randomized, double-blind, placebo-controlled trials have been done for lumateperone as a schizophrenia drug. In two of these studies, results for lumateperone at a 60-mg dose showed a “statistically significant separation from placebo on the primary endpoint, the Positive and Negative Syndrome Scale or PANSS total score.”

In a recent routine filing with the Securities and Exchange Commission, Intra-Cellular said it was having an “ongoing dialogue” with the FDA about lumateperone. The company in 2016 had announced that, in a phase 3 study known as ITI-007-302, lumateperone had not separated from placebo on the primary endpoint, change from baseline on the PANSS total score, in the predefined patient population. The active control for ITI-007-302, risperidone, did separate from placebo.

In the recent SEC filing, Intra-Cellular said the FDA already has confirmed that the results of ITI-007-302 did not preclude the submission of a new drug application.

Intra-Cellular also said “lumateperone was statistically significantly better than risperidone on key safety and tolerability parameters, and exhibited a safety profile similar to placebo” in the 302 study. Lumateperone’s failure to best placebo in the 302 test was “in part due to an unusually high placebo response at certain sites.”

For most patients taking antiplatelet and/or anticoagulant therapies, the proton pump inhibitor (PPI) pantoprazole is unnecessary, based on findings from the prospective COMPASS trial, which involved more than 17,000 participants.

Pantoprazole may reduce the risk of bleeding from gastroduodenal lesions, but it is unlikely to prevent upper-gastrointestinal events, reported lead author Paul Moayyedi, MB ChB, PhD, of McMaster University in Hamilton, Canada, and colleagues.

The investigators wrote in Gastroenterology, “Guidelines suggest that patients receiving the combination of antiplatelet and anticoagulant therapy should receive PPIs to reduce the risk of upper-GI bleeding. However … there are no randomized data to support the use of PPI therapy in patients taking oral anticoagulants, and a paucity of data relating to aspirin.”

To fill this knowledge gap, the investigators recruited 17,598 participants from 33 countries who had stable peripheral artery disease and cardiovascular disease. Participants were randomized to one of three groups: 100-mg aspirin once daily, 5-mg rivaroxaban twice daily, or a combination of 2.5-mg rivaroxaban twice daily with 100-mg aspirin once daily. This part of the trial was discontinued before completion because of early cardiovascular advantages associated with combination therapy over aspirin alone, and related findings were reported previously. While combination therapy did reduce cardiovascular risks, it had less favorable effects on gut health, highlighted by an associated increase in major GI bleeding events. Despite early cessation of the cardiovascular portion of the trial, the pantoprazole regimen was continued, offering a look at the effect of long-term PPI use on gut health.

At baseline, about two-thirds of participants (64%) were not taking a PPI, requiring randomization to either 40-mg pantoprazole once daily or matching placebo. The primary efficacy outcome was time to first upper-GI clinical event, defined as a composite of the following: upper-GI obstruction, perforation, at least five gastroduodenal erosions with at least 3 days of GI pain, symptomatic gastroduodenal ulcer involving at least 3 days of GI pain, overt upper-GI bleeding of unknown origin, occult bleeding (drop in hemoglobin of at least 2 g/dL), overt bleeding with a gastroduodenal lesion (active bleeding during endoscopy), or a symptomatic gastroduodenal ulcer involving at least 3 days of GI pain. In addition to this measure, the investigators evaluated a post-hoc endpoint with a looser definition of peptic ulcer events, most notably eliminating the requirement that a lesion be actively bleeding during endoscopy.

Most patients in the trial (78%) were male, and 23% were current smokers. Smaller proportions of the population were taking a nonsteroidal anti-inflammatory drug (5%) and/or had a history of peptic ulcer disease (2.6%). The median follow-up was 3.01 years, ranging from 2.49 to 3.59 years. Permanent discontinuations occurred at approximately equal rates in the pantoprazole (21%) and placebo (22%) group, after a median of 11 months (338 days). In both groups, more than 96% of participants who continued treatment took their medications as prescribed at least 80% of the time.

Analysis showed that upper-GI events occurred marginally less often in the pantoprazole group than the placebo group, but without statistical significance (1.2% vs. 1.3%; P = .35). Of the outcomes measured, only overt bleeding of gastroduodenal origin detected by radiography or endoscopy was statistically less common in the pantoprazole group than the placebo group, with a 48% reduced rate (0.2% vs. 0.4%; P = .03). No statistical efficacy differences or statistical interactions were detected between population subgroups.

“The data suggest that routine use of PPI therapy is not warranted for patients receiving low-dose rivaroxaban with or without aspirin for the prevention of atherothrombotic events in patients with stable coronary artery disease or symptomatic peripheral artery disease, as there was no overall impact on clinical upper-GI events or upper-GI bleeding,” the investigators wrote. “This is in contrast to previous systematic reviews of randomized trials reporting that PPIs were associated with a 50%-70% reduction in bleeding and symptomatic peptic ulcers related to nonsteroidal anti-inflammatory drugs, including in the critical care setting.”

Post-hoc analysis, which allowed for a broader definition of upper-GI events related to gastroduodenal ulcers, revealed a slightly greater reduction in risk of bleeding lesions in patients taking pantoprazole, compared with placebo (hazard ratio, 0.45), and additional risk reductions for peptic ulcers (HR, 0.46) and erosions (HR, 0.33). Ultimately, pantoprazole reduced the combined rate of post-hoc events by 56%.

The investigators noted that these ulcer- and erosion-reducing effects of pantoprazole align with previous reports. “It is therefore possible that PPIs might be beneficial for patients at particularly high risk for peptic ulcer disease who are also taking aspirin and/or anticoagulants,” the investigators concluded.

The COMPASS trial was funded by Bayer AG. The investigators disclosed additional relationships with Allergan, Takeda, Janssen, and others.
