Acne and Antiaging: Is There a Connection?
As a chronic inflammatory skin disease well known for its poor cosmesis including scarring, residual macular erythema, and postinflammatory pigment alteration, acne vulgaris may, according to recent research, confer some antiaging benefits to affected patients. In a research letter published online on September 27 in the Journal of Investigative Dermatology, Ribero et al analyzed white blood cells and found that women who said they had acne had longer telomeres (the "caps" at the end of chromosomes that protect them from deteriorating following repeated cell replication). Telomere length, or rather shortening, has been correlated with age-related degenerative change, according to Saum et al (Exp Gerontol. 2014;58:250-255), and therefore the thinking is that in women with acne, something is going on that maintains the length of the cellular guardians. Let's clarify a couple things to help us all understand the why and what.
The impetus of this study, according to Ribero et al, was the observation that women with acne show signs of aging later than those who have never had acne. I personally have not witnessed this finding in my patients, and given that acne in its essence is a disease of chronic inflammation resulting from, for example, persistent activation of toll-like receptor 2 (TLR2) and NOD-like receptor family pyrin domain containing 3 (NLRP3) pattern recognition receptors, one would think the skin damage accrued would make these individuals look older, right? Last I checked, pitted scarring does not make one immediately think of the fountain of youth.
The results from the study show that there is a link between acne and longer telomeres, but the study did not show that telomere length is a cause of acne, that women with longer telomeres had fewer signs of skin aging, or that women with acne lived longer.
Given these points, Ribero et al concluded that "delayed skin aging may be due to reduced senescence," which means that skin aging may be delayed because the longer telomeres in the cells protect them from deterioration. They did find that the expression of one gene in particular was reduced in women with acne--the regulatory gene zinc finger protein 420, ZNF420--suggesting that those without acne may produce more of a particular protein linked to that gene, though the significance is unclear.
What's the issue?
This study is interesting, but it is important not to make any broad conclusions, such as those who get acne will live longer or look younger longer regardless of other factors such as acne treatment, comorbidities, or even environmental factors. This study may give more support for the genetic contribution of acne, but much more work is needed to determine the clinical relevance. For starters, what about men?
Would you assure your acne patients that their disease may be for their own cosmetic good?

Sunscreen and Sperm: Can Chemical UV Filters Alter Sperm Function?
In an article published online on September 1 in Endocrinology, Rehfeld et al discussed their results after testing 29 UV filters. They found that 13 of 29 filters tested had in vitro effects on Ca2+: 4-methylbenzylidene camphor, 3-benzylidene camphor, menthyl anthranilate, isoamyl p-methoxycinnamate, ethylhexyl salicylate, benzylidene camphor sulfonic acid, homosalate, ethylhexyl methoxycinnamate, octcrylene, butyl methoxydibenzoylmethane, and diethylamino hydroxybenzoyl hexyl benzoate.
This study was prompted by a prior study by Schiffer et al (EMBO Rep. 2014;15:758-765) on multiple endocrine disrupting chemicals of which 33 of 96 tested chemicals induced Ca2+ signals in human sperm cells in vitro. Of these previously tested chemicals, some of the chemical sunscreen filters were the most potent, leading to the current study.
Rehfeld et al sought to determine how the UV filters affected calcium signaling, which is a pathway that is essential for sperm cells to be able to swim healthily. These calcium-signaling pathways usually are triggered by progesterone, but the authors showed that 13 of 29 UV filters (45%) also commenced calcium signaling. This effect began at low doses of the chemicals, below the levels of some UV filters found in people after whole-body application of sunscreens.
What’s the issue?
Are these chemical UV filters mimicking progesterone in vivo and could it be interfering with sperm motility? A suboptimal progesterone-induced Ca2+ influx has been associated with reduced male fertility and CatSper (cation channel of sperm) is essential for male fertility (Hum Reprod. 1995;10:120-124).
The UV filters tested are widely available in Europe and the United States. Although this study was in vitro, the in vivo effects will need to be explored. It has been reported by Chivsvert et al (Anal Chim Acta. 2012;752:11-29) that some UV filters can be transcutaneously absorbed into bodily tissues, which could be potentially important for men trying to conceive or for reproductively challenged couples.

Surgical Risks From Systemic Psoriasis Therapies
I am a coauthor on a recent literature review (J Am Acad Dermatol. 2016;75:798.e7-805.e7) that addressed a common question regarding the use of systemic agents: What should a clinician do if a patient on one of these therapies has an upcoming elective surgery?
Treatment with systemic immunomodulatory agents commonly is employed in patients with moderate to severe plaque psoriasis and psoriatic arthritis. In these individuals, the concern is that surgery may carry an increased risk for infectious or surgical complications. Based on the available literature, my coauthors and I sought to create recommendations for the perioperative management of systemic immunosuppressive therapies in patients with psoriasis and psoriatic arthritis. We conducted a literature review to examine studies that addressed the use of methotrexate, cyclosporine, and biologic agents in patients undergoing surgery. A total of 46 studies were examined, nearly all retrospective studies in patients with inflammatory bowel disease and rheumatoid arthritis.
Based on level III evidence, we concluded that infliximab, adalimumab, etanercept, methotrexate, and cyclosporine can be safely continued through low-risk operations in patients with psoriasis and psoriatic arthritis. For moderate- and high-risk surgeries, a case-by-case approach should be taken based on the patient’s individual risk factors and comorbidities.
What’s the issue?
This study does not provide specific guidelines because of limited and conflicting literature. However, it does provide general guidelines that hopefully will be augmented in the future. How will you handle this situation when it arises in your practice?

Scalp Psoriasis: Weighing Treatment Options
Scalp psoriasis often is the initial presentation of psoriasis, and it can be one of the most challenging aspects of the disease. It can be difficult to treat for several reasons. First, hair can interfere with topical therapy reaching its site of action on the scalp. Second, facial skin also can be exposed to these treatments with the associated risk for adverse events. Finally, compliance often is difficult.
An evidence-based review published online on September 21 in the American Journal of Clinical Dermatology examined treatments for scalp psoriasis, including newer systemic therapies. Of 475 studies initially identified from PubMed and 845 from Embase (up to May 2016), the review included 27 clinical trials, 4 papers reporting pooled analyses of other clinical trials, 10 open-label trials, 1 case series, and 2 case reports after excluding non-English literature.
Wang and Tsai noted that few randomized controlled trials have been performed specifically in scalp psoriasis. The authors found that topical corticosteroids provide good effects and are usually recommended as first-line treatment. Calcipotriol–betamethasone dipropionate is more highly effective than either of its individual components.
The analysis also suggested that localized phototherapy is better than generalized phototherapy on hair-bearing areas. Methotrexate, cyclosporine, fumaric acid esters, and acitretin are well-recognized agents in the treatment of psoriasis, but they located no published randomized controlled trials specifically evaluating these agents in scalp psoriasis. Wang and Tsai also commented that biologics and new small-molecule agents show excellent effects on scalp psoriasis, but the high cost of these treatments mean they may be limited to use in extensive scalp psoriasis. They suggested that more controlled studies are needed for an evidence-based approach to scalp psoriasis.
What’s the issue?
Scalp psoriasis can be an isolated condition or may occur in association with more extensive disease. There has been increased attention to its treatment over the last several years, with several new options. What is your preferred approach to scalp psoriasis?

In Orbit
When using biologic therapies for psoriasis, it is important to evaluate long-term efficacy (>4 years of follow-up). Biologic drug survival in psoriasis reflects long-term performance in real-life settings. Prior studies have yielded inconsistent results.
Vilarrasa et al (J Am Acad Dermatol. 2016;74:1066-1072) conducted an observational retrospective study called ORBIT (Outcome and Retention Rate of Biologic Treatments for Psoriasis) to determine drug survival (the mean length of time patients remain on a drug) in a cohort of 427 patients (63.5% male; mean age, 50.2 years) with moderate to severe psoriasis vulgaris (mean baseline psoriasis area and severity index [PASI], 16.4). In addition to determining mean drug survival times for etanercept, infliximab, adalimumab, and ustekinumab, investigators searched for variables that positively or negatively affected drug survival times. Data were extracted from clinical records of patients treated with biologic agents over a 4-year period. Drug survival was analyzed using the Kaplan-Meier method and the influence of several covariates was assessed using Cox regression.
The investigators evaluated 703 treatment courses. The overall median drug survival was 31.0 months. Cumulative probability of drug survival was lower in obese patients (23.0 months; 95% CI, 17.4-28.6) than in patients with body mass index less than 30 (37.3 months; 95% CI, 29.4-45.1; P=.001). Drug survival was significantly higher for ustekinumab than for any other biologic agent (log-rank test, P<.001). Multivariate analysis showed that obesity, etanercept treatment, and strict adherence to approved doses were associated with an increased probability of drug withdrawal, whereas ustekinumab treatment and PASI 75 and PASI 90 responses at week 16 prolonged drug survival. Data were collected retrospectively.
What’s the issue?
These results should help to educate patients and to manage expectations about drug efficacy.

Knowledge of the Platysma Muscle Anatomy in the Face Can Improve Cosmetic Outcomes
The platysma muscle has been widely studied in its course through the cervical region in an attempt to develop more effective surgical approaches for rejuvenation. As a person ages, the platysma muscle becomes thinner, less defined, and ptotic, which results in the clinical appearance of a sagging neck that prompts patients to undergo neck-lift procedures. However, little is known about the course of the platysma in the mid and lower face and the implications on facial aging.
Bae et al (Plast Reconstr Surg. 2016;138:365-371) performed a cadaveric dissection of the facial portion of the platysma muscle to delineate the morphology and extension of the muscle in the mid and lower face. Thirty-four adult hemifaces were dissected. The demographics were broken down by age (mean, 71.4 years; range, 41–93 years), gender (29 men; 5 women), and ethnicity (14 Korean; 20 Thai). The extension of the platysma was documented according to a grid the authors created. The grid was divided along 3 horizontal lines (H1–H3) and 3 vertical lines (V1–V3). The intersection of these lines created a grid that was comprised of 3×3 squares and was labeled superior (S1–S3), middle (M1–M3), and inferior (I1–I3). H1 was a line drawn horizontally from the tragus to the lateral orbit, H2 was a line from the earlobe to the nasal ala, and H3 was a line from the angle of the mandible to the corner of the mouth.
The extension pattern of the facial portion of the platysma muscle was classified into patterns: A (n=3; S1–S2, M1–M3, and I1-I3 were covered by the muscle), B-1 (n=20; M1–M3, I1–I3), B-2 (n=9; M1–M2, I1–I3), and C (n=2; I1-I3).
The platysma muscle is divided into anterior and posterior portions. The anterior platysma ascends superiorly and medially in the face to interdigitate with the depressor anguli oris and the depressor labii inferioris muscles. The morphology pattern of the posterior platysma varied and was classified into 1 of 3 patterns: straight (n=13), straight-curved (n=18), and curved (n=3). The straight pattern showed platysma fibers that travel parallel to the mandibular malar line and head toward the zygomaticus major or the orbicularis oculi muscles. The straight-curved type has fibers that travel straight from the neck to the face but then curve, heading toward the risorius, zygomaticus major, or orbicularis oculi muscle depending on the extent of the platysma muscle in the area. The curved type has fibers that run parallel to the zygomaticus arch and interdigitate with the orbicularis oculi muscle and either the risorius or zygomaticus major muscle.
What’s the issue?
For many years, the cervical platysma muscle was studied and surgical approaches were modified to enhance results. The authors of this study have taken the study of the platysma muscle further to delineate its course through the face. Knowledge of the various pathways of the muscle can help us determine the most natural direction to resuspend ptotic facial tissue during surgery and minimally invasive procedures such as thread-lifting. The most salient points include: (1) the lower one-third of the masseter muscle is covered by the platysma, and (2) straight-curved was the most common morphology type, suggesting that the vector for repositioning the platysma muscle is vertical.
Although Bae et al do not discuss the use of botulinum toxin (BTX) in the treatment of the platysma, the results of this study further support the importance of BTX to the lower face. We can look back at more than 14 years of cosmetic use of BTX for the glabella and see the reduced number of brow-lift surgeries nationwide. Although the preventative effects of BTX on brow depression still need to be scientifically proven, it may behoove us to think preventatively on the use of BTX in the platysma to minimize ptosis of the lower face and neck. The results of this anatomic study support the importance of tailoring the approach to the dynamic lines caused by the platysma muscle in each patient to address jowls and neck bands. Have you been offering lower face BTX treatments to patients in an effort to reduce lower face aging?
The platysma muscle has been widely studied in its course through the cervical region in an attempt to develop more effective surgical approaches for rejuvenation. As a person ages, the platysma muscle becomes thinner, less defined, and ptotic, which results in the clinical appearance of a sagging neck that prompts patients to undergo neck-lift procedures. However, little is known about the course of the platysma in the mid and lower face and the implications on facial aging.
Bae et al (Plast Reconstr Surg. 2016;138:365-371) performed a cadaveric dissection of the facial portion of the platysma muscle to delineate the morphology and extension of the muscle in the mid and lower face. Thirty-four adult hemifaces were dissected. The demographics were broken down by age (mean, 71.4 years; range, 41–93 years), gender (29 men; 5 women), and ethnicity (14 Korean; 20 Thai). The extension of the platysma was documented according to a grid the authors created. The grid was divided along 3 horizontal lines (H1–H3) and 3 vertical lines (V1–V3). The intersection of these lines created a grid that was comprised of 3×3 squares and was labeled superior (S1–S3), middle (M1–M3), and inferior (I1–I3). H1 was a line drawn horizontally from the tragus to the lateral orbit, H2 was a line from the earlobe to the nasal ala, and H3 was a line from the angle of the mandible to the corner of the mouth.
The extension pattern of the facial portion of the platysma muscle was classified into patterns: A (n=3; S1–S2, M1–M3, and I1-I3 were covered by the muscle), B-1 (n=20; M1–M3, I1–I3), B-2 (n=9; M1–M2, I1–I3), and C (n=2; I1-I3).
The platysma muscle is divided into anterior and posterior portions. The anterior platysma ascends superiorly and medially in the face to interdigitate with the depressor anguli oris and the depressor labii inferioris muscles. The morphology pattern of the posterior platysma varied and was classified into 1 of 3 patterns: straight (n=13), straight-curved (n=18), and curved (n=3). The straight pattern showed platysma fibers that travel parallel to the mandibular malar line and head toward the zygomaticus major or the orbicularis oculi muscles. The straight-curved type has fibers that travel straight from the neck to the face but then curve, heading toward the risorius, zygomaticus major, or orbicularis oculi muscle depending on the extent of the platysma muscle in the area. The curved type has fibers that run parallel to the zygomaticus arch and interdigitate with the orbicularis oculi muscle and either the risorius or zygomaticus major muscle.
What’s the issue?
For many years, the cervical platysma muscle was studied and surgical approaches were modified to enhance results. The authors of this study have taken the study of the platysma muscle further to delineate its course through the face. Knowledge of the various pathways of the muscle can help us determine the most natural direction to resuspend ptotic facial tissue during surgery and minimally invasive procedures such as thread-lifting. The most salient points include: (1) the lower one-third of the masseter muscle is covered by the platysma, and (2) straight-curved was the most common morphology type, suggesting that the vector for repositioning the platysma muscle is vertical.

Reducing Risk for Coronary Artery Disease
For the last decade, we have considered the cardioprotective benefit of biologics, especially in patients with chronic inflammatory diseases. Due to accelerated coronary artery disease, inflammatory pathways of psoriasis share connections with the mechanisms of atherosclerosis.
In a July 7 article published online in JAMA Dermatology, Hjuler et al investigated the association of biological therapy with changes in coronary artery disease progression, measured by serial coronary computed tomography (CT). Patients with severe psoriasis were enrolled in a single-center, prospective, controlled, observer-blinded clinical study. Between April 2011 and June 2014, biologic therapy (intervention group) and a matched control that did not receive the same therapy (control group) were initiated. Biological therapies included adalimumab, etanercept, infliximab, and ustekinumab, along with the possibility to switch between treatments to ensure inflammation control.
At baseline and 13-month follow-up, 28 treated patients (mean age [SD], 49.2 [10.2] years; 71% men; mean psoriasis area severity index [PASI][SD], 15.4 [4.3]) and 28 controls (mean age [SD], 52.8 [10.6] years; 71% men; mean PASI [SD], 12.4 [3.9]) underwent noncontrast coronary artery calcium (CAC) CT and contrast-enhanced coronary CT angiography. Changes in CAC score, number of coronary plaques, severity of luminal narrowing, composition, and vessel wall volume were measured.
In the intervention group, the CAC scores remained stable (mean yearly CAC change [SD], -16 [56]; P=.15) and progressed in the control group (14 [29]; P=.02). The severity of luminal narrowing in the diseased segments remained unchanged in the intervention group (Wilcoxon W=76; n=483; P=.39) but increased at follow-up in the control group (Wilcoxon W=281; n=414; P=.02). Luminal abnormalities remained unchanged in both groups.
The authors concluded that clinically effective treatment with biologic agents is associated with reduced coronary artery diseases in patients with severe psoriasis. These findings support a beneficial effect of biologic anti-inflammatory agents in preventing cardiovascular disease progression in addition to disease control in inflammatory diseases.
What’s the issue?
These findings give continued support to the cardioprotective effects of biologics in inflammatory diseases. How will these data change your prescribing habits?

Reversing Facial Fillers: How Much Hyaluronidase Is Needed to Dissolve Unwanted Filler?
Hyaluronic acid (HA) fillers are among the most commonly injected soft-tissue fillers worldwide. However, even with proper technique, there may be instances in which the filler becomes visible (Tyndall effect) or edematous, prompting the need to dissolve it. Not all HA fillers are identical; many differ in their degree of cross-linking or classification as monophasic or biphasic, which may affect the success in dissolving them with hyaluronidase. Rao et al (J Drugs Dermatol. 2014;13:1053-1056) published a study that looked at 2 commonly used hyaluronidase agents and how well they dissolved 4 commonly used HA fillers in the United States.
Rao et al performed an in vitro study using Vitrase (ovine testicular hyaluronidase)(Bausch & Lomb Incorporated) and Hylenex (recombinant human hyaluronidase)(Halozyme Therapeutics). The HA fillers tested were Restylane (Galderma Laboratories, LP), Juvéderm and Juvéderm Voluma (Allergan), and Belotero (Merz Aesthetics).
Phase 1 of the study looked at the volume of hyaluronidase on 3 of 4 fillers. The researchers utilized 0.1 mL of Vitrase or Hylenex to treat 0.2 mL of Restylane, Belotero, and Juvéderm. A control slide was kept for each filler. For Vitrase, 0.1 mL is 20 U of hyaluronidase. For Hylenex, 0.1 mL is 15 U of hyaluronidase. The filler and hyaluronidase were mixed together for 10 seconds using a 27-gauge needle. Photograph assessment of the slides was taken at 1 and 5 minutes.
Phase 2 of the study looked at the number of units of hyaluronidase on all 4 fillers. For this phase, 15 U and 30 U of Hylenex were mixed with 0.2 mL aliquots of each filler. Photographs and qualitative observations were taken at 1 and 5 minutes. The aliquots were observed for a total of 15 minutes.
For phase 1, the 2 hyaluronidase agents worked similarly on all 3 HA fillers. The greatest effect on dissolving or changing the shape of a filler was on Restylane, followed by Juvéderm and Belotero (a monophasic filler). The greatest effect was in the first minute and continued through the fifth minute. Even at 5 minutes, Belotero maintained most of its shape.
Phase 2 showed similar results with Restylane reacting the most to the hyaluronidase, followed by Juvéderm Voluma, Juvéderm, and Belotero. The higher dose (30 U) of hyaluronidase had a more dramatic effect on all fillers compared to the lower dose (15 U). Results were time dependent with the greatest changes seen at 5 minutes as opposed to 1 minute. The results of the 15-minute observation did not show any further changes. Belotero also maintained most of its shape during this phase.
What’s the issue?
With the increased number of HA fillers coming onto the market, it will become more important to understand the interaction between HA fillers and hyaluronidase. Hyaluronic acid fillers will vary in their degree of cross-linking, water absorption, and classification as monophasic (cohesive) or biphasic. Oftentimes, it is not until we use fillers in off-label manners that we realize some unintended consequences. We realized all too quickly that fillers, such as Restylane, placed superficially under eyelid skin gave an unsightly Tyndall effect. We then relied on hyaluronidase injections to resolve this issue. Furthermore, we learned that Juvéderm Ultra Plus XC could hold approximately 300% of its weight in water, causing unsightly eyelid edema in some patients. Luckily, the use of hyaluronidase can be a saving grace for physicians. However, the success of hyaluronidase injections varies. From the results of this study, it may be true that certain fillers need higher volumes or a higher number of units than other fillers to dissolve them. I would like to see this study expanded as newer HA fillers are brought onto the market.
Have you found that you have had to use varying amounts of hyaluronidase to address different filler complications?

Dermatologists Should Get the Point: Acupuncture for the Treatment of Skin Disorders
Complementary and alternative medicine has a definite adjunctive and even at times primary role in the medical management of patients. Its prevalence in the United States is estimated to be 38% and it is used to treat dermatologic conditions in 6% of patients (Harris et al; Smith et al). Acupuncture, a component of traditional Chinese medicine, has a prevalence of 0.6% to 1.4% and is used to treat 0.6% of dermatologic conditions (Smith et al; Cooper et al).
Acupuncture involves stimulation of specific points usually located along meridians. The source of stimulation on the skin can be elicited using needle points, pressure, or heat. Diseases disturb the body’s vital energy (qi), and stimulation along the appropriate meridian channel achieves balance and cures disease by restoring the normal circulation of the body’s qi.
Ma and Sivamani (J Altern Complement Med. 2015;21:520-529) performed a systematic review of articles indexed for MEDLINE, EMBASE, and the Cochrane Central Register using acupuncture therapy or acupuncture and skin diseases or dermatology as search terms to synthesize the evidence on the use of acupuncture as a primary treatment modality for dermatologic conditions. Twenty-four studies met inclusion criteria; of them, 17 showed statistically significant improvements (P<.05) in outcome measures. Specifically, acupuncture improved the outcome measures in the treatment of several dermatologic conditions including chloasma, dermatitis, facial elasticity, hyperhidrosis, pruritus, and urticaria.
What’s the issue?
Patients often have insight into potential available therapies for their medical problems. Hence, it is not unexpected that individuals with dermatologic conditions may not only be aware of complementary and alternative medicine approaches, such as acupuncture, but also seek dermatologists who can provide them with these possible therapeutic options. Although the frequency and duration of acupuncture treatments may not allow it to be a practical modality for all individuals, this treatment appears to be effective for reducing the severity of itch in patients with atopic dermatitis.
Should dermatologists incorporate acupuncture into their therapeutic armamentarium? Should national dermatology meetings provide courses on acupuncture technique? Should dermatology residency programs add competency in acupuncture management to their curriculum?

Complementary and alternative medicine has a definite adjunctive and even at times primary role in the medical management of patients. Its prevalence in the United States is estimated to be 38% and it is used to treat dermatologic conditions in 6% of patients (Harris et al; Smith et al). Acupuncture, a component of traditional Chinese medicine, has a prevalence of 0.6% to 1.4% and is used to treat 0.6% of dermatologic conditions (Smith et al; Cooper et al).
