The FP recognized that this could be a wart but was concerned that it might be a squamous cell carcinoma (SCC) related to HPV and sun exposure.

He performed a shave biopsy and the pathology report indicated it was an SCC in situ. (See the Watch & Learn video on “Shave biopsy.”)  At the follow-up visit, the FP reviewed the patient’s treatment options, which included topical 5% fluorouracil, topical imiquimod, and surgical excision. He also explained that the topical treatments were off label, so these options might have a lower success rate than the surgery.

The patient chose to have the surgery, even though he’d be out of work while the excision site was healing. The FP provided counseling about sun avoidance, the consistent use of a hat outdoors, and the use of sunscreens when exposed to the sun. He also referred the patient to a dermatologist who had extensive experience doing skin cancer surgery.

Atopic dermatitis associated with increased suicidality

Article Type
Changed

 

Patients with atopic dermatitis might face up to a 44% increased risk of suicidal ideation and are 36% more likely to attempt suicide than those without the disorder, a large meta-analysis has determined.

aniaostudio/Thinkstock.com

The analysis, which included data from studies published as far back as 1945, also found some correlation of increased suicide risk and increasing disease severity, although the numbers were small, Jeena K. Sandhu and her colleagues reported in JAMA Dermatology.

Both physical and psychological factors could be involved in the link, wrote Ms. Sandhu, a medical student at the University of Missouri–Kansas City, and her coauthors.

“Atopic dermatitis is associated with multiple physical comorbidities, such as asthma, allergic rhinitis, metabolic syndrome, and sleep disturbances, which all contribute to the overall physical burden of the disease. Many patients also have a profound psychosocial burden. Because of the visibility of the disease, patients may experience shame, embarrassment, and stigmatization,” they wrote.

But the disease also is associated with high levels of proinflammatory cytokines, and those proteins have been isolated in the cerebrospinal fluid of patients who have attempted suicide, the investigators noted. “Treatments targeting cytokines, such as interleukin-4 and interleukin-13, have been shown to decrease symptoms of depression and anxiety in patients with atopic dermatitis.”

The investigators plumbed several databases of medical literature, searching for studies that mentioned both atopic dermatitis (AD) and suicide, suicidal ideation, or suicidal behavior. They found 15 studies, published from 1945 to May 2018. Most (13) were cross sectional; the remainder were cohort studies. Together, they comprised a total of 4.7 million subjects, 310,681 of whom had AD. The analysis looked at risks in three areas: suicidal ideation, suicide attempts, and completed suicides.

Of the studies, 11 investigated suicidal ideation. Pooled data determined that patients with AD were a significant 44% more likely to experience suicidal ideation than those without the disease.

Three studies mentioned suicide attempts and had complete data for pooling. Taken together, they showed a significant 36% increased risk of attempted suicide among patients with AD, compared with those without the disorder.

Two studies investigated the prevalence of completed suicides among patients. One did report a significantly increased risk of 40%, compared with the control group, but it failed to report the number of suicides in the control group. The other study found no increased risk of completed suicides in patients with either mild or moderate to severe disease, compared with controls.

Two studies involved only pediatric patients. One, conducted in Korea, found a significant 23% increased risk of suicidal ideation and a 31% increased risk of attempted suicide. The other failed to find any increased risks in the overall analysis, but did find small increases in the risks of ideation and attempt in girls with AD, compared with healthy controls.

“Monitoring for suicidality in patients with atopic dermatitis is crucial to improving patient outcomes,” the team concluded. “Dermatology providers may use several tools to screen patients for suicidality. Asking patients about suicidal ideation with a question may be integrated into a patient visit. If a patient screens positive for suicidality, the dermatology provider should send a referral to the patient’s primary care or mental health provider for follow-up care. If the patient reports an orchestrated plan to commit suicide, this patient should be urgently referred to the emergency department for further assessment.”

Ms. Sandhu reported no financial disclosures.

Wart on scalp

The FP had seen many recalcitrant warts before, but rather than repeat the cryotherapy, he performed a shave biopsy to get a definitive diagnosis. (See the Watch & Learn video on “Shave biopsy.”) The biopsy revealed a well-differentiated squamous cell carcinoma (SCC).

This lesion may have started with a wart, as human papillomavirus (HPV) is both the cause of warts and a risk factor for cutaneous SCC. The FP referred the patient to a Mohs surgeon for complete excision of the SCC. He also provided counseling about sun avoidance, the consistent use of a hat outdoors, and the use of sunscreens when exposed to the sun.

How I Became a Derm Guru (And How You Can, Too)

How I Became a Derm Guru (And How You Can, Too)

Many years ago, when I was still in primary care (internal medicine), I thought I knew a bit about the practice of medicine. I was totally comfortable in the hospital (in those days, we saw our own patients twice a day in the hospital), including the ER, the OR, even obstetrics. MIs, shootings, stab wounds, renal failure—I would never say I had mastered them, but I was comfortable with most of what I saw. Deliveries, assisting with C-sections, performing lumbar punctures, performing and interpreting exercise tolerance tests, performing flexible sigmoidoscopies—no problem.

But the one thing that nearly always stopped me in my tracks was … you guessed it: dermatology complaints. Rashes, lesions, or any other skin complaint the least bit out of the ordinary were completely baffling to me. I still remember that feeling after all these years (and I still occasionally experience it!).

I felt like saying to those patients: What in the world would make you think I’d have any idea what that is? But of course, I couldn’t say that, so I’d mumble something, throw some cream at it, then quickly change the subject. Mind you, this was in a setting where a derm referral from us would take 4 to 6 months. And in case you’re wondering, the other providers in my department were as bad at derm as I was.

Long story short, it got to the point that I would scan my schedule every morning, praying I wouldn’t see the word “rash” or “skin.” But, of course, they still came—often just as my hand touched the doorknob to leave: “Oh, by the way, what about this …?” You get the picture. Many of you, if not most, live that picture.

I finally got up the nerve to go to our dermatology department to ask if I could follow one of the docs while he saw patients. Little did I know that practically every provider in the building had already done the same, and had been dismissed with words that essentially meant, “You? A mere PA? You can’t get there from here. Just send ’em to us.”

For a short time, I bought that line—but in the meantime, my patients were not getting the care they needed. So, driven in part by anger at the notion that a mere PA was simply unable to learn dermatology, I bought a decent textbook, Fitzpatrick’s Color Atlas of Dermatology, and started reading it. I also started collecting all the derm articles I could find in the journals, and read about those cases.

I won’t bore you with the grimy details, but what I did differently was work at learning derm (what a concept!). I started going to derm conferences, bought a good camera and started taking pictures with it, and continued to buy books (this was in the pre-computer days of the ’80s) and actually read them.

Continue to: And a funny thing happened...

 

 

And a funny thing happened: The more I read, the more diagnoses I recognized on my patients. My colleagues and the clinic schedulers took note of this and began sending me their problem cases. Even the derm department, beleaguered as usual by huge backlogs of patients, started sending patients to me. By 1985, even though I was in the internal medicine department, I had transitioned to doing derm fulltime. And that’s what I’ve been doing since.

Around 1992, I discovered that I was one of 6 dermatology PAs in this country. Last time I checked, our numbers were approaching 4,000. So, yes, derm is indeed difficult, but rocket science it isn’t.

Being the pedantic sort that I am, and finding that whole experience so enlightening, I resolved to make it my mission to foster the use of PAs in dermatology—part of which involves the education of those PAs, by means of taking students but also by writing articles (several hundred at last count) and lecturing at conferences and at PA programs. Nearing retirement, I only practice two days a week, but I write and publish at least 5 clinical articles a month, all of which are based on real cases: my cases, using my photos, doing new research on each case. This keeps my knowledge fresh and my 75-year-old mind sharp, helps ward off burnout, and, most importantly, saves lives while reducing patient discomfort.

What follows are 10 dermatology pearls that I have gleaned along the way. My apologies to my former students and attendees at my lectures who’ve heard all this before:

1 If the treatment for your diagnosis isn’t working, consider another diagnosis. Here’s an example (Figure 1): A man in his 50s was sent to dermatology for psoriasis that wasn’t responding to a biologic. Was it really psoriasis? A KOH prep quickly showed it to be tinea corporis, which cleared completely with a month’s worth of oral terbinafine (250 mg qid).

Dermatophytosis misdiagnosed as psoriasis

Continue to: #2...

 

 

2 The correct diagnosis dictates correct treatment. This may sound obvious, but in primary care, the emphasis is often on “let’s try this” or “let’s try that,” an understandable approach to a symptomatic patient with an uncertain diagnosis. But by the time he finally gets to dermatology, the patient has tried a whole bag full of prescription and OTC products given for numerous, totally different diagnoses. A better approach might be to expedite an urgent referral to dermatology, when possible.

3 Cutaneous fungal infections (ie, dermatophytosis) are vastly overdiagnosed, especially by novices. If you truly suspect it, ask about a potential source; one doesn’t acquire a fungal infection out of thin air. It must come from a person, animal, or occasionally, the soil. It also helps if the victim has been rendered susceptible by the injudicious use of steroids. Better yet, find the fungus with a microscopic examination (KOH prep) or culture. Finally, remember, not everything round and scaly is fungal (see Figure 2).

Granuloma annulare

4 Remember these ancient words of wisdom regarding skin complaints: (a) A diagnosis is seldom made if not entertained, (b) you won’t entertain it if you’ve never heard of it, (c) you will not see it if you’re not looking for it, and (d) even if you did see it, you would not “see” it because you’re not looking for it. Dermatology is far deeper and wider than most imagine it to be. The trick is to expose yourself to as many different diagnoses as possible, by reading and attending lectures, ahead of the possible sighting. Figures 3 and 4 offer examples of common conditions that are seldom recognized outside dermatology.

5 Skin cancer can present as a rash. Examples abound, such as mammary and extramammary Paget’s disease (Figure 5), mycosis fungoides, metastatic breast cancer (Figure 6), and superficial basal cell carcinoma. A biopsy is usually required to diagnose these, but you wouldn’t think to do that if you’d never heard of the condition.

Paget’s disease, type 2 and Metastatic breast cancer

6 Melanoma doesn’t typically arise from a mole or other pre-existing lesion. Far more often, it arises “de novo,” out of nothing. So, in general, we’re not worried about “moles” (nevi) unless there’s a history of change (see Figure 7).

Melanoma

Continue to: #7...

 

 

7 When looking for skin cancer, pay as much attention to the owner as to the lesion. The most common skin cancers—basal cell and squamous cell carcinoma—usually occur on sun-damaged, fair-skinned, blue-eyed older patients. Though there are certainly exceptions to this paradigm, it pays to be generally suspicious of any odd lesion seen on these patients (Figure 8).

Dermatoheliosis

8 It’s practically impossible to overstate the role of atopy when evaluating pediatric skin complaints. These children—20% of all newborns!—are born with thin, dry, sensitive, overreactive skin that is prone to eczema and urticaria. They will also have a marked tendency to develop seasonal allergies, allergic rhinitis, and asthma. Parents find it difficult to accept the genetic basis for atopic dermatitis (Figure 9), preferring instead to blame everything on laundry detergent or food. Education (of oneself first!) is the key.

Atopic dermatitis

9 “Infections” are not always what they seem. These pearls may help: a) There are many causes of localized erythema, swelling, and tenderness that have nothing to do with infection. Examples include relapsing polychondritis (Figure 10) and cutaneous lupus (Figure 11). b) Skin cancer, such as basal cell carcinoma (see Figure 12), is often mistaken for infection. c) Some infections have less conventional or obvious sources; those caused by atypical mycobacteria (see Figure 13), leishmaniasis (see Figure 14), and sporothrix (see Figure 15), are good examples of this phenomenon. Consider thinking outside the box.

Relapsing polychondritis; Cutaneous lupus; Perinasal basal cell carcinoma

10 Overcome your fear of steroids by educating yourself about their safe use. Glucocorticoids (eg, triamcinolone, prednisone, betamethasone) are extremely useful in treating common derm conditions. We see patients every day who are so frightened of steroids, they won’t even consider using them because some well-meaning medical provider scared them to death. The proper use of these miraculous products could easily be the subject of an entire article. For now, I’ll advise you to read about their safe use in any number of dermatology texts (including online publications).

But of course, I couldn’t say that, so I’d mumble something, throw some cream at it, then quickly change the subject. Mind you, this was in a setting where a derm referral from us would take 4 to 6 months. And in case you’re wondering, the other providers in my department were as bad at derm as I was.

Long story short, it got to the point that I would scan my schedule every morning, praying I wouldn’t see the word “rash” or “skin.” But, of course, they still came—often just as my hand touched the doorknob to leave: “Oh, by the way, what about this …?” You get the picture. Many of you, if not most, live that picture.

I finally got up the nerve to go to our dermatology department to ask if I could follow one of the docs while he saw patients. Little did I know that practically every provider in the building had already done the same, and had been dismissed with words that essentially meant, “You? A mere PA? You can’t get there from here. Just send ’em to us.”

For a short time, I bought that line—but in the meantime, my patients were not getting the care they needed. So, driven in part by anger at the notion that a mere PA was simply unable to learn dermatology, I bought a decent textbook, Fitzpatrick’s Color Atlas of Dermatology, and started reading it. I also started collecting all the derm articles I could find in the journals, and read about those cases.

I won’t bore you with the grimy details, but what I did differently was work at learning derm (what a concept!). I started going to derm conferences, bought a good camera and started taking pictures with it, and continued to buy books (this was in the pre-computer days of the ’80s) and actually read them.

And a funny thing happened: The more I read, the more diagnoses I recognized on my patients. My colleagues and the clinic schedulers took note of this and began sending me their problem cases. Even the derm department, beleaguered as usual by huge backlogs of patients, started sending patients to me. By 1985, even though I was in the internal medicine department, I had transitioned to doing derm fulltime. And that’s what I’ve been doing since.

Around 1992, I discovered that I was one of 6 dermatology PAs in this country. Last time I checked, our numbers were approaching 4,000. So, yes, derm is indeed difficult, but rocket science it isn’t.

Being the pedantic sort that I am, and finding that whole experience so enlightening, I resolved to make it my mission to foster the use of PAs in dermatology—part of which involves the education of those PAs, by means of taking students but also by writing articles (several hundred at last count) and lecturing at conferences and at PA programs. Nearing retirement, I only practice two days a week, but I write and publish at least 5 clinical articles a month, all of which are based on real cases: my cases, using my photos, doing new research on each case. This keeps my knowledge fresh and my 75-year-old mind sharp, helps ward off burnout, and, most importantly, saves lives while reducing patient discomfort.

What follows are 10 dermatology pearls that I have gleaned along the way. My apologies to my former students and attendees at my lectures who’ve heard all this before:

1 If the treatment for your diagnosis isn’t working, consider another diagnosis. Here’s an example (Figure 1): A man in his 50s was sent to dermatology for psoriasis that wasn’t responding to a biologic. Was it really psoriasis? A KOH prep quickly showed it to be tinea corporis, which cleared completely with a month’s worth of oral terbinafine (250 mg qid).

2 The correct diagnosis dictates correct treatment. This may sound obvious, but in primary care, the emphasis is often on “let’s try this” or “let’s try that,” an understandable approach to a symptomatic patient with an uncertain diagnosis. But by the time he finally gets to dermatology, the patient has tried a whole bag full of prescription and OTC products given for numerous, totally different diagnoses. A better approach might be to expedite an urgent referral to dermatology, when possible.

3 Cutaneous fungal infections (ie, dermatophytosis) are vastly overdiagnosed, especially by novices. If you truly suspect it, ask about a potential source; one doesn’t acquire a fungal infection out of thin air. It must come from a person, animal, or occasionally, the soil. It also helps if the victim has been rendered susceptible by the injudicious use of steroids. Better yet, find the fungus with a microscopic examination (KOH prep) or culture. Finally, remember, not everything round and scaly is fungal (see Figure 2).

Granuloma annulare

4 Remember these ancient words of wisdom regarding skin complaints: (a) A diagnosis is seldom made if not entertained, (b) you won’t entertain it if you’ve never heard of it, (c) you will not see it if you’re not looking for it, and (d) even if you did see it, you would not “see” it because you’re not looking for it. Dermatology is far deeper and wider than most imagine it to be. The trick is to expose yourself to as many different diagnoses as possible, by reading and attending lectures, ahead of the possible sighting. Figures 3 and 4 offer examples of common conditions that are seldom recognized outside dermatology.

5 Skin cancer can present as a rash. Examples abound, such as mammary and extramammary Paget’s disease (Figure 5), mycosis fungoides, metastatic breast cancer (Figure 6), and superficial basal cell carcinoma. A biopsy is usually required to diagnose these, but you wouldn’t think to do that if you’d never heard of the condition.

Paget’s disease, type 2 and Metastatic breast cancer

6 Melanoma doesn’t typically arise from a mole or other pre-existing lesion. Far more often, it arises “de novo,” out of nothing. So, in general, we’re not worried about “moles” (nevi) unless there’s a history of change (see Figure 7).

Melanoma

Continue to: #7...

 

 

7 When looking for skin cancer, pay as much attention to the owner as to the lesion. The most common skin cancers—basal cell and squamous cell carcinoma—usually occur on sun-damaged, fair-skinned, blue-eyed older patients. Though there are certainly exceptions to this paradigm, it pays to be generally suspicious of any odd lesion seen on these patients (Figure 8).

Dermatoheliosis

8 It’s practically impossible to overstate the role of atopy when evaluating pediatric skin complaints. These children—20% of all newborns!—are born with thin, dry, sensitive, overreactive skin that is prone to eczema and urticaria. They will also have a marked tendency to develop seasonal allergies, allergic rhinitis, and asthma. Parents find it difficult to accept the genetic basis for atopic dermatitis (Figure 9), preferring instead to blame everything on laundry detergent or food. Education (of oneself first!) is the key.

Atopic dermatitis

9 “Infections” are not always what they seem. These pearls may help: a) There are many causes of localized erythema, swelling, and tenderness that have nothing to do with infection. Examples include relapsing polychondritis (Figure 10) and cutaneous lupus (Figure 11). b) Skin cancer, such as basal cell carcinoma (see Figure 12), is often mistaken for infection. c) Some infections have less conventional or obvious sources; those caused by atypical mycobacteria (see Figure 13), leishmaniasis (see Figure 14), and sporothrix (see Figure 15), are good examples of this phenomenon. Consider thinking outside the box.

Relapsing polychondritis; Cutaneous lupus; Perinasal basal cell carcinoma

10 Overcome your fear of steroids by educating yourself about their safe use. Glucocorticoids (eg, triamcinolone, prednisone, betamethasone) are extremely useful in treating common derm conditions. We see patients every day who are so frightened of steroids, they won’t even consider using them because some well-meaning medical provider scared them to death. The proper use of these miraculous products could easily be the subject of an entire article. For now, I’ll advise you to read about their safe use in any number of dermatology texts (including online publications).

Many years ago, when I was still in primary care (internal medicine), I thought I knew a bit about the practice of medicine. I was totally comfortable in the hospital (in those days, we saw our own patients twice a day in the hospital), including the ER, the OR, even obstetrics. MIs, shootings, stab wounds, renal failure—I would never say I had mastered them, but I was comfortable with most of what I saw. Deliveries, assisting with C-sections, performing lumbar punctures, performing and interpreting exercise tolerance tests, performing flexible sigmoidoscopies—no problem.

But the one thing that nearly always stopped me in my tracks was … you guessed it: dermatology complaints. Rashes, lesions, or any other skin complaint the least bit out of the ordinary were completely baffling to me. I still remember that feeling after all these years (and I still occasionally experience it!).

I felt like saying to those patients: What in the world would make you think I’d have any idea what that is? But of course, I couldn’t say that, so I’d mumble something, throw some cream at it, then quickly change the subject. Mind you, this was in a setting where a derm referral from us would take 4 to 6 months. And in case you’re wondering, the other providers in my department were as bad at derm as I was.

Natural killer cells implicated in psoriatic arthritis

Article Type
Changed

 

A specific type of natural killer cell has for the first time been implicated as playing a key contributory role in the development of psoriatic arthritis in patients with psoriasis.

Bruce Jancin/MDedge News
Dr. Vinod Chandran

This natural killer cell interacts with the CD94/NKG2A receptor, part of a system believed to have been in place in humans for more than 90 million years.

“We believe there is a possible role for the innate immune system in the development of psoriatic arthritis and its distinction from psoriasis,” Vinod Chandran, MD, PhD, declared at the annual meeting of the American College of Rheumatology.

Dr. Chandran, of the University of Toronto, presented an analysis of a discovery cohort comprising 1,155 patients with dermatologist-diagnosed psoriasis of greater than 10 years duration, 664 rheumatologist-diagnosed psoriatic arthritis patients, and 3,118 controls, all participants in the International Psoriasis and Arthritis Research Team program. These findings were then independently confirmed in a separate University of Toronto replication cohort of 659 psoriasis patients, 1,177 psoriatic arthritis patients of European ancestry, and 1,096 controls.

By way of background, the rheumatologist explained that psoriasis and psoriatic arthritis are known to differ in terms of their genetic architecture, the biggest difference being in the HLA class I region, where HLA-C predominates in psoriasis and HLA-B in psoriatic arthritis. These structurally unrelated forms of HLA class I are known to educate natural killer cells and shape their function. Dr. Chandran and his coinvestigators were eager to shed new light on the mechanisms by which this leads to rheumatic disease.

Humans can be divided into three groups based upon whether they are HLA-B21 methionine/methionine (M/M), HLA-B21 M/threonine (T), or HLA-B21 T/T. The B21 M types educate CD94/NKG2A-positive natural killer cells by delivering functional peptides to the CD94/NKG2A receptor, while the B21 T/T version does not.



In the discovery cohort, individuals with psoriatic arthritis turned out to be 36% more likely to be HLA-B21 M/M or HLA-B21 M/T than were the psoriasis patients, while the psoriasis patients were 22% less likely to be B21 M–positive than controls. These relationships were confirmed in the replication cohort, where psoriatic arthritis patients were 40% more likely to be B21 M–positive than psoriasis patients, and psoriasis patients were 18% less likely to be B21 M–positive than controls, with all of these differences being statistically significant.

While this is translational science, Dr. Chandran explained that it has important clinical implications. He and his coinvestigators are developing a genetic marker panel to differentiate psoriatic arthritis from psoriasis, as are other research groups. And the Toronto investigators are now convinced that including HLA-B21 M/M and HLA-B21 M/T in their evolving genetic test is worthwhile in terms of boosting the test’s predictive power. The 36%-40% increased risk of psoriatic arthritis associated with B21 M–positivity isn’t sufficiently large for it to serve as a standalone test, but when the genetic test panel is finalized and the investigators can evaluate its positive and negative predictive value, it will be clear that the B21 M component will provide added value, he predicted.

Because psoriatic arthritis can take on a variety of disparate forms clinically, Dr. Chandran and his coworkers believe their genetic test will prove most useful for nonrheumatologists, especially dermatologists and primary care physicians.

He reported having no relevant financial relationships regarding this study, funded by the Canadian Institutes of Health Research, the Krembil Foundation, and the Arthritis Foundation.

Increased cancer risk in dermatomyositis has temporal limits

Article Type
Changed

The increased risk of cancer associated with anti-TIF1-Ab-positive dermatomyositis is limited almost exclusively to 3 years on either side of the onset of dermatomyositis, new research suggests.

Idiopathic inflammatory myopathy have been associated with malignancy, in particular dermatomyositis (DM) and the DM-specific antitranscriptional intermediary factor 1 antibody (anti-TIF1-Ab).

Around one-fifth of the 236 patients diagnosed with DM in the current study, published online Dec. 7 in Rheumatology, were anti-TIF1-Ab positive, and these patients had a more than threefold higher risk of developing cancer comapared with patients who were anti-TIF1-Ab negative (hazard ratio = 3.4, 95% confidence interval, 2.2-5.4; P less than .01).

Overall, 38% of patients in the anti-TIF1-Ab-positive group developed cancer during the 10-year follow-up, compared with 15% of patients with anti-TIF1-Ab-negative DM.

However, all the cancers in the anti-TIF1-Ab-positive group occurred within the 3 years before the onset of DM or within 2.5 years after onset. No anti-TIF1-Ab-positive patients developed cancers after this time, but some patients in the anti-TIF1-Ab-negative group did.

“This finding is not likely to be due to a disparity in follow-up time between anti-TIF1-Ab-positive and -negative cases, as the median follow-up times were similar for both groups: 10 years and 12 years, respectively,” wrote Alexander Oldroyd, MBChB, a clinical research fellow in the Centre for Musculoskeletal Research at the University of Manchester (England), and his coauthors. “Further, this finding is unlikely to be due to differences in cancer detection methods, as both cohorts’ cancer diagnoses were identified through HSCIC [U.K. Health and Social Care Information Centre] data, ensuring capture of all incident cancers during the follow-up period.”

Anti-TIF1-Ab-positive patients were more likely to develop cancer if they were older. None of the 15 anti-TIF1-Ab-positive patients who were aged under 39 when they developed DM went on to develop cancer. But cancer developed in around half of the anti-TIF1-Ab-positive patients who were aged 39 years or older when their DM began.


The anti-TIF1 antibody is commonly found in juvenile DM, but previous research has not found an association with an increased risk of cancer in this younger patient population.

“Our findings add strength to the hypothesis that there exists a subset of young adult anti-TIF1-Ab-positive cases who do not have a discernible increased risk of cancer, similar to that observed in TIF1-Ab-positive juvenile DM,” the authors wrote. They suggested that given the increased risk of malignancy in older patients who were anti-TIF1-Ab positive, this group should be subject to more detailed cancer screening.

Breast cancer was the most common malignancy among both anti-TIF1-Ab-positive and anti-TIF1-Ab-negative patients (33% and 25%, respectively). However, ovarian cancer was significantly more common among the anti-TIF1-Ab-positive patients than among the anti-TIF1-Ab-negative patients (19% vs. 2%; P less than .05); four of the five ovarian cancers in the entire cohort occurred in the anti-TIF1-Ab-positive group.

The authors noted that this confirmed the finding of a number of previous studies suggesting an increased risk of ovarian cancer with DM.

“However, this is the first large study to identify that ovarian cancer is overrepresented in anti-TIF1-Ab-positive individuals, suggesting that the true association between DM and ovarian cancer may be through possession of anti-TIF1-Abs,” they noted.

The authors wrote that they had aimed to inform cancer screening strategies among patients with DM.

“It may be that a focus on screening for cancer within the first 3 years after DM onset and particularly screening for ovarian cancer in anti-TIF1-Ab-positive female patients may be required,” they wrote. “Our findings also strengthen the hypothesis that inflammatory myopathies represent a paraneoplastic reaction initiated by attempted immune-mediated clearance of a cancer.”

The increased risk of cancer associated with anti-TIF1-Ab-positive dermatomyositis is limited almost exclusively to 3 years on either side of the onset of dermatomyositis, new research suggests.

Idiopathic inflammatory myopathy have been associated with malignancy, in particular dermatomyositis (DM) and the DM-specific antitranscriptional intermediary factor 1 antibody (anti-TIF1-Ab).

Around one-fifth of the 236 patients diagnosed with DM in the current study, published online Dec. 7 in Rheumatology, were anti-TIF1-Ab positive, and these patients had a more than threefold higher risk of developing cancer comapared with patients who were anti-TIF1-Ab negative (hazard ratio = 3.4, 95% confidence interval, 2.2-5.4; P less than .01).

Overall, 38% of patients in the anti-TIF1-Ab-positive group developed cancer during the 10-year follow-up, compared with 15% of patients with anti-TIF1-Ab-negative DM.

However, all the cancers in the anti-TIF1-Ab-positive group occurred within the 3 years before the onset of DM or within 2.5 years after onset. No anti-TIF1-Ab-positive patients developed cancers after this time, but some patients in the anti-TIF1-Ab-negative group did.

“This finding is not likely to be due to a disparity in follow-up time between anti-TIF1-Ab-positive and -negative cases, as the median follow-up times were similar for both groups: 10 years and 12 years, respectively,” wrote Alexander Oldroyd, MBChB, a clinical research fellow in the Centre for Musculoskeletal Research at the University of Manchester (England), and his coauthors. “Further, this finding is unlikely to be due to differences in cancer detection methods, as both cohorts’ cancer diagnoses were identified through HSCIC [U.K. Health and Social Care Information Centre] data, ensuring capture of all incident cancers during the follow-up period.”

Anti-TIF1-Ab-positive patients were more likely to develop cancer if they were older. None of the 15 anti-TIF1-Ab-positive patients who were aged under 39 when they developed DM went on to develop cancer. But cancer developed in around half of the anti-TIF1-Ab-positive patients who were aged 39 years or older when their DM began.


The anti-TIF1 antibody is commonly found in juvenile DM, but previous research has not found an association with an increased risk of cancer in this younger patient population.

New worldwide atopic dermatitis survey brings big surprises

Article Type
Changed

 

– A major worldwide survey of the 12-month prevalence of atopic dermatitis (AD) across the course of life provides new insights into global disease trends, Jonathan I. Silverberg, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.

Dr. Jonathan Silverberg

Among the most important takeaways from this Internet-based survey of more than 273,645 infants, children, and adults in 18 countries across five continents conducted in 2017 was that “global atopic dermatitis prevalence appears to be higher in adults, at 10%, than in younger cohorts, where it’s 4%-8%, which I think is quite provocative and requires further study and confirmation,” said Dr. Silverberg, a dermatologist at Northwestern University in Chicago.

“Let’s keep in mind that there’s this accepted dogma in the literature than atopic dermatitis is somehow only a childhood disorder – it doesn’t affect adults. Well, these data tell a very different story because we’re actually seeing overall highest prevalences throughout the world occurring in adulthood,” based on the U.K. Working Party’s Diagnostic Criteria for Atopic Dermatitis (Br J Dermatol. 1994 Sep;131[3]:383-96).

This is the biggest epidemiologic survey ever to examine the 12-month prevalence and severity of AD around the world for both adults and children. Survey respondents included 172,627 adults aged 18 years and older, 34,212 adolescents aged 12-17 years, 54,806 children aged 2-11 years, and more than 12,000 infants.

Key findings from the study include the following:

  • AD prevalence rates varied widely from country to country around the world, as well as by age groups (see graphic).
  • The highest rate in adults was observed in China. South Korea had the highest rates in both children and adolescents. The top AD rates in infancy occurred in France and the United Kingdom.
  • Rates across the age spectrum were consistently lowest in Israel and Switzerland.

“These kinds of patterns raise fascinating questions about the potential risk factors or protective factors that happen in different countries. There are some startling differences in terms of the different regions,” Dr. Silverberg observed. “Certain regions of the world really stand out as having much higher prevalences, particularly China and South Korea, and then as you get into the adult years, Brazil and Mexico, which I think are areas that, at least in the global atopic dermatitis epidemiology community, are not quite as well recognized as being hot spots for atopic dermatitis.”



Indeed, the 12-month prevalence rate of AD among adults was 14% in Mexico and 12% in Brazil, as compared with 13% in Saudi Arabia, 11% in Australia and Spain, 10% in Canada and the United Kingdom, and 9% in the United States.

The prevalence was generally lowest in infants, then jumped substantially within countries during the childhood years, declined slightly in adolescents, and then peaked in adulthood.

AD severity was assessed using PO-SCORAD, the Patient-Oriented Scoring AD measure. Most affected individuals had moderate AD as defined by a PO-SCORAD score of 25-50. Across the age spectrum, the highest proportion of infants with AD who had moderate disease was in China, with 72%. In Taiwan, 63% of children with AD had moderate disease, as did 68% of adolescents and an equal proportion of adults.

In the United Kingdom, 49% percent of infants with AD had severe disease, making that country the world leader in the youngest age group. Severe AD was most common among Turkish children, where 30% of kids with the skin disease had a PO-SCORAD score greater than 50. In Brazil, 31% of adolescents with AD had severe disease, the world’s highest rate in that age group. Among adults with AD, the world’s highest rate of severe disease was 25%, which was seen in the United States, Brazil, and Saudi Arabia.

Across the age spectrum, Japan had a consistently lower-end, overall, 12-month AD prevalence rate of 5%. Germany, Italy, and France had overall rates of 6%, 7%, and 8%, respectively. The rate was 9% in the United States and Canada, and it was 10% in Australia.

Dr. Silverberg performed validation analyses using the Patient-Oriented Eczema Measure (POEM) and diagnostic criteria similar to the earlier landmark International Study of Asthma and Allergies in Childhood, or ISAAC (Lancet. 1998 Apr 25;351[9111]:1225-32). This was a huge study that excluded the United States, leaving a hole in the epidemiologic picture of the disease that the new survey fills. The validation analyses were supportive of the main findings based on the U.K. Working Party criteria.

Dr. Silverberg reported serving as a consultant to Pfizer, which sponsored the global epidemiologic survey, as well as to roughly a dozen other pharmaceutical companies.

Algorithm proposes approach for managing TNF inhibitor–induced psoriasis

Article Type
Changed

 

Patients with tumor necrosis factor inhibitor–induced psoriasis could potentially be switched to a different drug class if they have moderate to severe skin eruption or mild skin eruption with an uncontrolled underlying disease such as inflammatory bowel disease, psoriasis, psoriatic arthritis, or rheumatoid arthritis, according to a new treatment algorithm proposed by researchers from Brigham and Women’s Hospital and Harvard Medical School in Boston.

Dr. Joseph F. Merola

The researchers outlined the prevalence of tumor necrosis factor–alpha inhibitor (TNFi)-induced psoriasis in a literature review of inflammatory bowel disease (IBD), psoriasis, psoriatic arthritis (PsA), and rheumatoid arthritis (RA) and identified an estimated rate of between 2.3% and 5% in patients with RA and between 1.6% and 2.7% in patients with IBD. Although there have been reports of TNFi-induced psoriasis in patients with psoriasis and PsA, the prevalence is unclear, they wrote in the Journal of Psoriasis and Psoriatic Arthritis.

The authors then created an algorithm to manage and treat TNFi-induced psoriasiform skin eruptions with decisions to continue therapy and “treat through” symptoms, switch to a different anti-TNF therapy, or switch to a different drug class based on severity of symptoms, whether the underlying disease is well controlled, and how patients with those underlying diseases have fared with those specific therapies or agents.

“We’ve shifted gears over the past decade, and we’ve gone from having very few agents and trying to keep patients desperately on one or two agents because we didn’t want to have to give up on them for their other comorbid disease, whether it was Crohn’s, colitis, RA, or whatever it may be,” senior author Joseph Merola, MD, director of the Center for Skin and Related Musculoskeletal Diseases at Brigham and Women’s Hospital, Boston, said in an interview. “We’re now in an area where we can have an algorithm like this, and we have so many more mechanistic options to move to.”

Dr. Merola, who is board certified in dermatology and rheumatology, said the algorithm is meant to “open a dialogue” with other specialists in different areas and raise awareness of treatments in related but separate fields. For diseases not often seen by more than one specialty, with the exception of psoriasis and PsA, he said that “the idea is to start a dialogue and increase communication between specialists.”



Dr. Merola noted that while the algorithm in many respects is meant to guide a physician in a specialty in appropriate medication decisions, at the same time he hopes that “it opens a dialogue and communication with the other specialty who tends to oversee this particular disease state or class of medicine to really work together to try to find the right drug for the right person.”

For patients with a mild skin eruption and a controlled underlying disease, the algorithm recommends a “treat through” approach by continuing anti-TNF therapy and treating psoriasis symptoms with topical steroids, ultraviolet therapy, methotrexate, cyclosporine, or acitretin, and to consider dapsone in cases of pustular psoriasis. However, the researchers noted that “treat through” studies have reported complete symptom resolution in 26%-41% of patients.

For patients with recalcitrant or worsening TNFi-induced psoriasis or patients with mild skin eruptions with an uncontrolled underlying disease, the researchers proposed considering switching to a different anti-TNF therapy, although studies have shown complete resolution of symptoms in only 5%-37% of patients.

If patients worsen from there, or if they have moderate to-severe skin eruption with uncontrolled underlying disease, they could be considered for switching to a different drug class and treated based on their underlying disease, along with treatment for psoriasis symptoms. This approach has been shown to completely resolve lesions in up to 64% of cases, they said. IBD patients could benefit from ustekinumab, vedolizumab, 6-mercaptopurine, or azathioprine as an alternative to anti-TNF therapy. Those patients with psoriasis should be considered for guselkumab, while ustekinumab, ixekizumab, secukinumab, and apremilast are effective treatments for patients with psoriasis and PsA. Patients with RA could receive treatment with tocilizumab, rituximab, abatacept, and tofacitinib, the authors wrote.

Dr. Merola reported serving as a consultant and/or investigator for Merck Research Laboratories, AbbVie, Dermavant, Eli Lilly, Novartis, Janssen, UCB, Samumed, Celgene, Sanofi Regeneron, GlaxoSmithKline, Almirall, Sun Pharma, Biogen, Pfizer, Incyte, Aclaris, and Leo Pharma.

“We’ve shifted gears over the past decade, and we’ve gone from having very few agents and trying to keep patients desperately on one or two agents because we didn’t want to have to give up on them for their other comorbid disease, whether it was Crohn’s, colitis, RA, or whatever it may be,” senior author Joseph Merola, MD, director of the Center for Skin and Related Musculoskeletal Diseases at Brigham and Women’s Hospital, Boston, said in an interview. “We’re now in an area where we can have an algorithm like this, and we have so many more mechanistic options to move to.”

Dr. Merola, who is board certified in dermatology and rheumatology, said the algorithm is meant to “open a dialogue” with other specialists in different areas and raise awareness of treatments in related but separate fields. For diseases not often seen by more than one specialty, with the exception of psoriasis and PsA, he said that “the idea is to start a dialogue and increase communication between specialists.”



Dr. Merola noted that while the algorithm in many respects is meant to guide a physician in a specialty in appropriate medication decisions, at the same time he hopes that “it opens a dialogue and communication with the other specialty who tends to oversee this particular disease state or class of medicine to really work together to try to find the right drug for the right person.”

For patients with a mild skin eruption and a controlled underlying disease, the algorithm recommends a “treat through” approach by continuing anti-TNF therapy and treating psoriasis symptoms with topical steroids, ultraviolet therapy, methotrexate, cyclosporine, or acitretin, and to consider dapsone in cases of pustular psoriasis. However, the researchers noted that “treat through” studies have reported complete symptom resolution in 26%-41% of patients.

For patients with recalcitrant or worsening TNFi-induced psoriasis or patients with mild skin eruptions with an uncontrolled underlying disease, the researchers proposed considering switching to a different anti-TNF therapy, although studies have shown complete resolution of symptoms in only 5%-37% of patients.

If patients worsen from there, or if they have moderate to-severe skin eruption with uncontrolled underlying disease, they could be considered for switching to a different drug class and treated based on their underlying disease, along with treatment for psoriasis symptoms. This approach has been shown to completely resolve lesions in up to 64% of cases, they said. IBD patients could benefit from ustekinumab, vedolizumab, 6-mercaptopurine, or azathioprine as an alternative to anti-TNF therapy. Those patients with psoriasis should be considered for guselkumab, while ustekinumab, ixekizumab, secukinumab, and apremilast are effective treatments for patients with psoriasis and PsA. Patients with RA could receive treatment with tocilizumab, rituximab, abatacept, and tofacitinib, the authors wrote.

Patients with tumor necrosis factor inhibitor–induced psoriasis could potentially be switched to a different drug class if they have moderate to severe skin eruption or mild skin eruption with an uncontrolled underlying disease such as inflammatory bowel disease, psoriasis, psoriatic arthritis, or rheumatoid arthritis, according to a new treatment algorithm proposed by researchers from Brigham and Women’s Hospital and Harvard Medical School in Boston.

Dr. Joseph F. Merola

The researchers outlined the prevalence of tumor necrosis factor–alpha inhibitor (TNFi)-induced psoriasis in a literature review of inflammatory bowel disease (IBD), psoriasis, psoriatic arthritis (PsA), and rheumatoid arthritis (RA) and identified an estimated rate of between 2.3% and 5% in patients with RA and between 1.6% and 2.7% in patients with IBD. Although there have been reports of TNFi-induced psoriasis in patients with psoriasis and PsA, the prevalence is unclear, they wrote in the Journal of Psoriasis and Psoriatic Arthritis.

The authors then created an algorithm to manage and treat TNFi-induced psoriasiform skin eruptions with decisions to continue therapy and “treat through” symptoms, switch to a different anti-TNF therapy, or switch to a different drug class based on severity of symptoms, whether the underlying disease is well controlled, and how patients with those underlying diseases have fared with those specific therapies or agents.

When Skin Damage Takes Sides

When Skin Damage Takes Sides

A 61-year-old man is sent to dermatology by his primary care provider for evaluation of several facial lesions. Although they have been present for years, the patient says they have never caused any symptoms.

The patient’s work history includes extensive outdoor activity, as well as more than 20 years of driving a truck. He is now retired and spends most of his days fishing.

He has a history of at least two unspecified skin cancers but denies receiving facial radiation treatment. He has been a smoker since age 12 and admits to heavy drinking.

When Skin Damage Takes Sides

EXAMINATION
The patient’s face is uneven in appearance, with deep wrinkles and multiple areas of discoloration. His skin is type III.

Multiple open and closed comedones are seen around the left malar and brow areas, where the underlying skin has a whitish look to it. The comedones are not inflamed, and no pustules are observed. Some of the comedones extend into the infra-orbital area on the left side of his face. Almost no such changes are seen on the right side.

There is no increase in hair in the affected areas and no skin changes observed on his hands or arms, other than moderately severe sun damage.

What is the diagnosis?

 

 

DISCUSSION
In the 1930s, two French dermatologists, Favre and Racouchot, began to see several cases like this one. Following a review of available literature, they published their findings, calling the condition “nodular elastosis with cysts and comedones.” This quickly became known as Favre-Racouchot syndrome (FRS), the name it still bears today.

FRS is quite common, especially on the faces of white men older than 50. More men than woman are affected, and smoking almost certainly contributes to the problem.

The connection between FRS and sun exposure is well established: the basophilic degeneration of the dermis (solar elastosis) seen in FRS is identical to that seen from overexposure to the sun. Another clue to the cause is exemplified in cases involving truck drivers, since the side of the face nearest the window is usually affected more than the other side. In most countries, the left side of the face sustains the most damage; in countries with right-hand drive, the right side of the face is affected.

Significant focal nodular solar elastosis, along with open and closed comedones, notably worse on the more sun-exposed side, is unique to FRS. The lack of increase in facial hair in the affected area is significant, in that it effectively rules out the only other major item in the differential: porphyria cutanea tarda.

Treatment is problematic at best. Except in younger patients, sunscreens are largely a waste. The comedones can be manually extracted, but recurrence is certain. For the truly motivated patient, laser resurfacing and peels can help. To slow the progression of the disease, smoking cessation is necessary.

TAKE-HOME LEARNING POINTS

  • Favre-Racouchot syndrome (FRS) is most commonly seen in older men with a history of excessive chronic sun exposure. Most are smokers.
  • FRS primarily affects the malar and lateral brow areas with nodular elastosis, in which are embedded multiple cysts and comedones.
  • In the United States, FRS is usually more pronounced on the left side of the face.
  • Other signs of chronic sun damage (actinic weathering, also known as dermatoheliosis) are almost always seen over the entire face of FRS patients.

Growing lesion on lip

The FP recognized the lesion as a probable squamous cell carcinoma (SCC) due to its appearance and location on the lower lip. He was also aware that immunosuppressive medications increase a patient's risk for SCC.

The FP performed a shave biopsy of a portion of the lesion and the result confirmed SCC. (See the Watch & Learn video on “Shave biopsy.”)  A careful head and neck exam did not reveal palpable lymph nodes. Given the location of the lesion and the risk for metastases, the FP referred the patient for Mohs surgery and provided counseling about sun avoidance, the consistent use of a hat outdoors, and the use of sunscreens when exposed to the sun.
