FDA: 246 new reports on breast implant-associated lymphoma
The Food and Drug Administration has identified 457 unique cases of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL) and 9 related deaths since 2010, and received 246 new medical device reports (MDRs) regarding BIA-ALCL between September 2017 and September 2018, according to an update from the agency’s Center for Devices and Radiological Health.
That brings the total number of reports to 660; however, that number reflects duplicative cases, Binita Ashar, MD, a general surgeon and the director of the division of surgical devices at the center, said in a statement.
“These types of increases in the MDRs are to be expected and may include past cases that were not previously reported to the FDA,” Dr. Ashar said, addressing the high number of new reports. “The increased number of MDRs contributes to our evolving understanding of BIA-ALCL and represents a more thorough and comprehensive analysis.”
BIA-ALCL is a type of non-Hodgkin lymphoma and a known risk from breast implants that was first communicated by the FDA in 2011. Regular updates have been provided with respect to related medical device reports, cases, deaths, and known risks.
“We hope that this information prompts providers and patients to have important, informed conversations about breast implants and the risk of BIA-ALCL. At the same time, we remain committed to working in partnership with all stakeholders to continue to study, understand, and provide updates about this important public health issue,” Dr. Ashar said.
To that end, the center also issued a Letter to Health Care Providers to “encourage those who regularly treat patients, including primary care physicians and gynecologists, to learn about BIA-ALCL in patients with breast implants.”
Patients and providers are encouraged to file MDRs with the FDA via MedWatch, the FDA Safety Information and Adverse Event Reporting program, she said.

Melatonin update, Part 1
Found in various plant and animal species, including humans, melatonin (N-acetyl-5-methoxytryptamine) is best known for its daily fluctuations in circulating levels that regulate circadian rhythms. But this ancient serotonin derivative, stimulated by beta-adrenergic receptors, is the primary neuroendocrine product of the pineal gland (discovered as such in 1917) in humans and a dynamic compound with diverse roles in human health levels of which decrease with age.1,2 Over the last quarter of a century, we have arrived at a much greater understanding of the varied biological functions of this highly lipophilic hormone, which is now recognized as the strongest endogenous antioxidant, particularly potent against hydroxyl radicals, the most harmful of reactive oxygen species, and known to protect mitochondria and DNA from direct oxidative harm.2-4 Directly or via its circadian impact, melatonin also affects skin as well as core body temperature.1 This column is a . Next month’s column will address some more of the activities of this dynamic hormone while concentrating on the interaction of melatonin and ultraviolet radiation.
Early studies
In the mid-1990s, Bangha et al. performed several studies in healthy human volunteers that demonstrated that topically applied melatonin suppressed UVB-induced erythema (with one study showing pre- and posttreatment as effective and a subsequent one showing only pretreatment as effective), and also found that melatonin appears to have the potential to accumulate in the stratum corneum with extended release into the blood system through cutaneous delivery.5-7
A randomized, double-blind study by Dreher et al. in 12 healthy adults (6 women and 6 men, all white, aged 29-49 years) considered the short-term photoprotective effects of topically applied vitamin C, vitamin E, and melatonin, alone or in combination, 30 minutes after UV exposure. A dose-dependent photoprotective effect was associated with melatonin, and photoprotective properties were enhanced when melatonin in was combined with vitamins C and E.8
The following year, Dreher et al. evaluated the short-term photoprotective effects of the same compounds in a randomized, double-blind, placebo-controlled human study. Each antioxidant was topically applied alone or in combination after UV exposure in a single application (immediately or 30 minutes after UV exposure) or in multiple applications 30 minutes, 1 hour, and 2 hours after UV exposure (totaling three applications). Interestingly, no photoprotective effects were seen. The researchers concluded that given the speed of cutaneous damage from UV radiation, antioxidants likely must be delivered at the appropriate site in sufficient doses at the outset of and during active oxidative harm.9
In 2004, Fischer et al. conducted a clinical study of 15 healthy volunteers to test the skin penetration activity of melatonin 0.01% in a cream and 0.01% and 0.03% in a solution. During a 24-hour period, researchers obtained blood samples for melatonin measurement prior to application at 9 a.m. as well as 1, 4, 8, and 24 hours after application. Preapplication serum melatonin levels ranged from 0.6 to 15.9 pg/mL. The mean serum value 24 hours later after application of the 0.01% melatonin cream was 9.0 pg/mL. For the 0.01% solution group, the mean melatonin level was 12.7 pg/mL 24 hours after application. Melatonin levels also substantially rose just 1 and 8 hours later in the 0.03% solution group, with cumulative melatonin measured as 7.1 pg/mL in the 0.01% cream group, 8.6 pg/mL in the 0.01% solution participants, and 15.7 pg/mL in the 0.03% group. The investigators concluded that as a strong lipophilic compound melatonin penetrates the skin with serum blood levels increasing in a dose- and galenic-dependent manner without prompting spikes above the physiological range.10
Wound healing and atopic dermatitis
In 2006, Sener et al. reported that topically applied and systemically administered melatonin was successful as a pressure ulcer treatment in rats.11 Four years later, in a study using a chronic wound model in rats with pinealectomy that suppressed basal melatonin, Ozler et al. found that systemic and topical melatonin treatment were equally effective in imparting wound healing effects.12
A study in mice conducted by Kim et al. at around the same time showed that topically applied melatonin, by reducing total IgE in serum and interleukin-4 and interferon-gamma production by activated CD4(+) T cells, inhibits atopic dermatitis–like skin lesion development engendered by 2,4-dinitrofluorobenzene (DNFB) treatment in NC/Nga mice.13
More recently, Abbaszadeh et al. have suggested that melatonin has the potential to enhance the therapeutic ratio in radiation oncology, and to be more effective at reducing skin damage in this setting when used in optimal and non-toxic doses.2
Pigmentation disorders
Melatonin and serotonin are thought to have potential to ameliorate or attenuate the spread of vitiligo.1 In addition, melatonin appears to have potential in the realm of hyperpigmentation treatment. Investigators have found that the combination of topical melatonin 5% and a daily dose of 3 g of oral melatonin over 120 days significantly reduces Melasma Area Severity Index scores in comparison to placebo; the improvement is attributed primarily to the use of topical melatonin.14,15
Androgenetic alopecia
In 2018, Hatem et al. designed nanostructured lipid carriers to better deliver melatonin in antioxidant oils to treat androgenic alopecia. They found that the carriers achieved a sustained release of 6 hours and raised the skin deposition of melatonin 4.5-fold in the stratum corneum, 7-fold in the epidermis, and 6.8-fold in the dermis compared with a melatonin solution. The nanostructured lipid carriers also improved on clinical results, compared to the melatonin formula, by increasing hair density and thickness and reducing hair loss in patients with androgenic alopecia.16
Conclusion
Studies in humans have shown that through systemic administration and, particularly, topical application. Demonstrated to be safe and effective, topically applied melatonin appears to warrant serious consideration as a skin-protective, anti-aging tool in the dermatologic armamentarium.

Winter exfoliation: A multicultural approach
Winter or postwinter exfoliation may seem counterintuitive to some patients because skin is often more dry because of cold weather and dry heat from heaters in the home, car, and workplace. Some patients even admit to using emollients less frequently in the winter because they are too cold to do it after bathing or are covering more of their body. But winter exfoliation can be an important method for improving skin hydration by aiding skin cell turnover, removing surface flaky skin, and enhancing penetration of moisturizers and active ingredients applied afterward. Here we explore exfoliation techniques used in various cultures around the world.
Ancient Egypt: Egyptians are credited with the first exfoliation techniques. Mechanical exfoliation was practiced in ancient Egypt via pumice stones, as well as alabaster particles, and scrubs made from sand or plants, such as aloe vera. (Although the subject is beyond the scope of this article, the first use of chemical exfoliation, using sour milk, which contains lactic acid, has been credited to ancient Egypt.)
Iran: Most traditional Iranian households are familiar with kiseh and sefidab, used for exfoliation as often as once a week. Kiseh is a special loofah-like exfoliating mitt, often hand woven. Sefidab is a whitish ball that looks like a dense piece of chalk made from animal fats and natural minerals that is rubbed on the kiseh, which is then rubbed on the skin. Exfoliation results as the sefidab and top layers of skin come off in gray white rolls, which are then rinsed off. The dead skin left on the mitt is known as “chairk.” Archaeological excavations have provided evidence that sefidab may have been used in Persian cosmetics as long ago as 2000 BC–4500 BC, as part of Zoroastrian traditions.
Korea: Koreans have long been known for practicing skin exfoliation. Here in Los Angeles, especially in Koreatown, many Korean spas or bathhouses, known as jjimjilbang, can be found; these provide various therapies, particularly “detoxification” in hot tubs, saunas (many with different stones and crystal minerals for healing properties), computer rooms, restaurants, theater rooms. They also provide body scrubs, or seshin: A soak in the hot tub for at least 30 minutes is recommended, followed by a hot water rinse and a scrub by a “ddemiri” (a scrub practitioner), who intensely scrubs the skin from head to toe using a roughened cloth. Going into a hot room or sauna is recommended after the scrub for relaxation, with the belief that the sweat won’t be blocked by dirty or clogged pores. Scrubs in jjimjilbang are recommended as often as once per week.
Indigenous people of the Americas and Caribbean: Sea salt is used commonly as an exfoliant among people from Caribbean countries and those of indigenous ancestry in the Americas (North America, including Hawaii, and Central and South America). Finer-grained sea salt is commonly found in the showers of my friends of Afro-Caribbean and indigenous American descent. While sugar is less coarse and easy to wash off in warm water, finer-grained sea salt provides more friction but is not as rough as coarse sea salt. Fine sea salt, because it is less coarse, can also be used on the face, if used carefully. While the effect of topical salt on skin microbes is unknown, cutaneous sodium storage has been found to strengthen the antimicrobial barrier function and boost macrophage host defense (Cell Metab. 2015 Mar 3;21[3]:493-501). Additionally, it has been noted that some Native Americans used dried corncobs for exfoliation. The people of the Comanche tribe would use sand from the bottom of a river bed to scrub the skin (similarly, Polynesian people have been known to use crushed sea shells for this purpose).
India (Ayurveda): Garshana is a dry brushing technique performed in Ayurvedic medicine. Dry brushing may be performed with a bristle brush or with slightly roughened silk gloves. The motion of dry brushing is intended to stimulate lymphatic drainage for elimination of toxins from the body. Circular strokes are used on the stomach and joints (shoulders, elbows, knees, wrists, hips, and ankles), and long sweeping strokes are used on the arms and legs. It is recommended for the morning, upon awakening and before a shower, because it is a stimulating practice. Sometimes oils, specific to an individual’s “dosha” (constitutional type or energy as defined by Ayurveda) – are applied afterward in a similar head-to-toe motion as a self-massage called Abhyanga.
Japan: Shaving, particularly facial shaving, is frequently done not just among men in Japan, but also among women who have shaved their faces and skin for years as a method of exfoliation for skin rejuvenation. In the United States, facial shaving among women has evolved to a method of exfoliation called “dermaplaning,” which involves dry shaving hairs (including facial vellus hairs) as well as top layers of stratum corneum. The procedure uses of a 25-centimeter (10-inch) scalpel, which curves into a sharp point. Potential risks include irritation from friction, as well as folliculitis.
France: It is not certain whether “gommage” originated in France, but in French, it means “to erase” because the rubbing action is similar to erasing a word. In gommage, a paste is applied to the skin and allowed to dry slightly while gentle enzymes digest dead skin cells on the surface; then it is rubbed off, taking skin cells with it. Most of what comes off is the product itself, but this may include some skin cells. One commonly used enzyme in gommage is papain, derived from the papaya fruit. Gommage was popular with facials before stronger chemical exfoliants like alpha-hydroxy acids became widely available commercially.
West Africa (Ghana, Nigeria): A long mesh body exfoliator, much like a tightly woven fishing net made of nylon, is common in Ghanaian and Nigerian households. The textured washcloth typically stretches up to 3 times the size of a regular washcloth, making it easy to scrub hard-to-reach places like the back.
Worldwide: Around the world in places where coffee beans are native, including Kenya and other parts of Africa, the Middle East, South America, Australia, and Hawaii, coffee beans are used as a skin exfoliant. Coffee grounds can however, should be used cautiously in showers as they can coagulate in water and clog drains and pipes. One tradition in Kenya is to crush and rub coffee beans on the skin with a piece of sugarcane to remove top layers of skin. Often too harsh to use directly, coffee grounds in cosmetic formulations are often mixed with oils or shea butter to create a smoother texture.
May this list grow as we continue to learn from the skin care techniques practiced in different cultures around the world.

Winter or postwinter exfoliation may seem counterintuitive to some patients because skin is often more dry because of cold weather and dry heat from heaters in the home, car, and workplace. Some patients even admit to using emollients less frequently in the winter because they are too cold to do it after bathing or are covering more of their body. But winter exfoliation can be an important method for improving skin hydration by aiding skin cell turnover, removing surface flaky skin, and enhancing penetration of moisturizers and active ingredients applied afterward. Here we explore exfoliation techniques used in various cultures around the world.
Ancient Egypt: Egyptians are credited with the first exfoliation techniques. Mechanical exfoliation was practiced in ancient Egypt via pumice stones, as well as alabaster particles, and scrubs made from sand or plants, such as aloe vera. (Although the subject is beyond the scope of this article, the first use of chemical exfoliation, using sour milk, which contains lactic acid, has been credited to ancient Egypt.)
Iran: Most traditional Iranian households are familiar with kiseh and sefidab, used for exfoliation as often as once a week. Kiseh is a special loofah-like exfoliating mitt, often hand woven. Sefidab is a whitish ball that looks like a dense piece of chalk made from animal fats and natural minerals that is rubbed on the kiseh, which is then rubbed on the skin. Exfoliation results as the sefidab and top layers of skin come off in gray white rolls, which are then rinsed off.

Fine-tuning the male aesthetic consultation includes consideration of gender-specific wrinkle pattern
ORLANDO – The , a dermatologist in private practice in Arlington, Va. And he may not even be sure what he’s looking for.
However, he probably knows what he doesn’t like about his appearance. When men are questioned, the three areas they are most concerned about is their hairline, their eyes, and their jawline, said Dr. Keaney, speaking at the Orlando Dermatology Aesthetic and Clinical Conference.
It’s important to evaluate men differently, not just for anatomic differences from women, but also for behavioral and psychological factors unique to men as aesthetic patients, he noted.
Anatomic differences are significant and fundamentally shape treatment decisions, Dr. Keaney said. Broadly speaking, “the male face is traditionally more square, with a prominent supraorbital ridge.” Rather than emphasizing breadth across the cheeks, as in rejuvenation for women, a strong, youthful male face will have a square jaw, appropriate width across the cheeks, and a strong brow line with an arch that is flatter than what women seek.
Male cosmetic goals can be complicated by the fact that men “age poorly” and tend to look older than their stated age, he continued, referring to a study that found that men appear about one-third year older than their age, and women about a half year younger. A higher rate of smoking and excess ultraviolet light exposure among men may contribute to this discrepancy, he said.
Overall, men see steady atrophy of facial soft tissue throughout adulthood, in contrast to women who see a more rapid decline that starts at menopause. This makes sense in the context of the slow drop in circulating testosterone that men see beginning at about age 30, at which time men can expect a decrease of about 1% per year, he noted.
A common opener from men, said Dr. Keaney, is “’I look tired.’ When I hear that, I’m thinking about the eyes.” Men are more likely to develop tear troughs and a sunken appearance because of their larger orbital cavities and smaller orbital fat pads, so periocular fillers are often a treatment tool to consider.
Around mens’ eyes, “it’s not just the presence, but the pattern of wrinkles that guides treatment,” he noted. At the lateral canthi, both at rest and with maximum smile, the predominant wrinkle pattern in crows’ feet is the lower fan. The cheek elevator musculature, including the zygomaticus major, are more involved in animation around the eyes with smiling, which is important because reaching for botulinum toxin alone is probably not going to give the patient his desired effect, he added.
Other differences in the male wrinkle pattern can be found on the brow. The “U” contraction pattern between the brows is more common in men than women, at least partly because men have greater involvement of the procerus muscle, Dr. Keaney said.
Taking all of this into account, caution is the watchword when using botulinum toxin for the glabellar and brow region. “Beware of eyebrow ptosis: avoid the frontalis in patients with eyebrow ptosis,” he said. Treating the corrugators can also be an unwise move, since toxin can diffuse to the inferior fibers of the frontalis muscle, he added.
For men with jawline concerns, consider a combination approach, Dr. Keaney said. The lower face and neck can be rejuvenated by a redraping solution, such as skin tightening with high frequency ultrasound or radiofrequency ablation.
Sometimes, a clean, tight sweep of jawline can be restored with dermal fillers to the lower face, along with a noninvasive fat reduction approach, said Dr. Keaney.
Knowing men’s unique anatomy and aging patterns is only half the battle, though. “How you communicate with men and evaluate them has to take into account that you might be seeing a sweaty, nervous, treatment-naive patient,” at the initial consultation, said Dr. Keaney. “Do men care? Yes, but men display a different set of motivations.”
Plan for all of this to take time. “The initial consultation tends to be longer” for male patients, who are “less savvy” about cosmetic procedures than women, he pointed out.
A clear discussion of side effects is critical when discussing treatment options with men. “If they get a side effect, you’ll never see them again – and you won’t ever hear about it,” he added.
Though overall, women have been shown to be more sensitive to pain, in cosmetic procedures, “men are less tolerant of pain.” Plan for this, set reasonable expectations but be proactive about pain control, and still expect a need for some hand-holding, said Dr. Keaney.
“Men do not like surprises,” he added. Clearly define what expected side effects may be, what they’ll look like, and what downtime the patient should expect.
For Dr. Keaney’s part, he’s found that the best way to retain men in his cosmetic practice is to “start with a home run treatment to earn trust.” Men often appreciate a slow and steady approach to addressing concerns. “Make sure to connect the treatment plan to the primary cosmetic concern.”
Dr. Keaney reported that he has relationships with multiple pharmaceutical and cosmetic companies.

EXPERT ANALYSIS FROM ODAC 2019
Small White Spots on the Lips
The Diagnosis: Fordyce Granules
Fordyce granules are prevalent benign anatomic variations that occur in approximately 80% of the population.1 The spots usually present as multiple (usually >10) 1- to 2-mm, painless, yellow-white papules in a symmetric bilateral distribution. They are normal superficial sebaceous glands seen on mucosal surfaces including the oral mucosa, lips, and genitalia. The papules are asymptomatic, and patients often are unaware of their presence. They can appear at any age and can last for months to years. No treatment is indicated, and patients need only reassurance.1
There are several differential diagnoses.2 Granular cell tumors present as solitary, yellowish or pink, slightly indurated, nonmobile, firm masses that usually measure less than 2 cm in diameter and can be associated with local paresthesia. The oral cavity is the second most common site after the skin and usually involves the dorsum of the tongue; however, granular cell tumors also may develop in the substance of the buccal mucosa, lips, or floor of the mouth. On histopathology, the neoplasm is composed of cells with granular cytoplasm that is of neural origin. Granular cell tumors are slow growing and may be present for months.

Mucoceles of the mouth are solitary, bluish clear, fluctuant, dome-shaped, well-demarcated nodules that usually appear on the lower lip.3 They are caused by rupture of a salivary gland duct due to minor trauma. Mucin is excreted into the surrounding soft tissues, leading to abrupt nontender swelling over the next several weeks. If they originate deeper within the lip they may appear normal in color. Most range from 1 to 2 mm in diameter but can grow to up to several centimeters in size. Other affected sites may include the ventral tongue, posterior buccal mucosa, or soft palate. Excisional biopsy and conservative surgical excision are recommended for diagnosis and management, respectively.3
Oral leukoplakia is a sharply demarcated, white, mucosal plaque that represents either epithelial dysplasia, carcinoma in situ, invasive carcinoma, or hyperkeratosis of unknown etiology. It is a clinical diagnosis of exclusion. The patient may present with a hoarse voice and history of tobacco use. The risk for malignant transformation to squamous cell carcinoma varies from 0% to 20% over the course of 30
years.4 The lesions occur on any mucosal surface, cannot be rubbed off, and usually are asymptomatic.5 The ventral tongue, floor of the mouth, and soft palate are associated with epithelial dysplasia and invasive carcinoma more often than other mucosal sites. There are 2 main types of leukoplakia: localized (unilateral plaque) and proliferative. Because of the risk for cancer, biopsy always is indicated and should be taken from different areas of the lesion (ie, red, verrucous, or nodular areas) if the lesion is nonhomogeneous. Treatment involves excision in the setting of dysplasia or invasive carcinoma. Photodynamic therapy has been shown to reduce the size of oral leukoplakia lesions and is being studied as an alternative therapy.5
Herpes simplex virus type 1 is a common infection of the oral mucosa that classically causes multiple vesicular lesions with an inflammatory erythematous base.6 The lesions are painful and may last for 10 to 14 days. Patients also may develop systemic symptoms such as fever and malaise. Once primary infection with herpes simplex virus has occurred, the virus lives in a latent state in ganglion neurons and can reactivate.6

The Diagnosis: Fordyce Granules
Fordyce granules are prevalent benign anatomic variations that occur in approximately 80% of the population.1 The spots usually present as multiple (usually >10) 1- to 2-mm, painless, yellow-white papules in a symmetric bilateral distribution. They are normal superficial sebaceous glands seen on mucosal surfaces including the oral mucosa, lips, and genitalia. The papules are asymptomatic, and patients often are unaware of their presence. They can appear at any age and can last for months to years. No treatment is indicated, and patients need only reassurance.1
There are several differential diagnoses.2 Granular cell tumors present as solitary, yellowish or pink, slightly indurated, nonmobile, firm masses that usually measure less than 2 cm in diameter and can be associated with local paresthesia. The oral cavity is the second most common site after the skin and usually involves the dorsum of the tongue; however, granular cell tumors also may develop in the substance of the buccal mucosa, lips, or floor of the mouth. On histopathology, the neoplasm is composed of cells with granular cytoplasm that is of neural origin. Granular cell tumors are slow growing and may be present for months. The mean age of onset is in the fourth decade, and females are more likely to be affected. Excisional biopsy is diagnostic and curative.2

Platelet-rich plasma: Is your practice ready?
ORLANDO – Platelet-rich plasma offers much for patients and dermatologists: It’s low-risk, has a low cost of entry, and usefully augments other medications and procedures for androgenetic alopecia and facial rejuvenation.
But there’s work to be done in standardizing its use and really understanding where, when, and for whom platelet-rich plasma (PRP) will be best used, said Dierdre Hooper, MD, a dermatologist in private practice in New Orleans.
As far back as the 1970s, PRP was used as a transfusion product, with use expanding during the following decade. “It’s really the ‘everywhere’ product,’” said Dr. Hooper, speaking at the Aesthetic, Surgical, and Clinical Dermatology Conference (ODAC).
Over the course of the past four decades, PRP has been explored for musculoskeletal healing, in gynecology, urology, cardiac surgery, ophthalmology, and for plastic surgery. “Initial skepticism has given way as some evidence is building,” said Dr. Hooper.
PRP, considered a biologic product, is produced by centrifuging a donor venipuncture. Among the pros of using PRP in a clinical practice, said Dr. Hooper, is the fact that numerous clinical studies do show benefit. The risk is low, as is the cost, and downtime is brief. All of these contribute to attractiveness to patients, who also like the idea of an all-natural product with an autologous source.
But consensus is lacking about some key aspects of utilization, including the best mode of preparation and optimal treatment schedule. Outcomes can be unpredictable, making it tough to say how cost-effective the regimen will be for a particular patient. “The ‘cons’ just come down to no consensus,” said Dr. Hooper.
Some of the basic science makes a compelling case for PRP: Activated platelets have secretory granules. These modify the pericellular milieu through release of a variety of growth factors by secretory granules. “We all were taught back in the day that platelets adhere to promote clotting, but they do a lot more than that – when the platelet is activated, it releases growth factors,” said Dr. Hooper. “Big picture? Think: This is how we heal.”
After blood collection, the sample is centrifuged. The goal of centrifuging is to achieve a platelet concentration of 1 to 1.5 million platelets per mL, or four to six times the platelet concentration seen in whole blood. In practice, there are variations in the mode of preparation, and in an individual’s platelet level at the time of venipuncture, said Dr. Hooper, so it’s hard to know what the platelet “dose” is from PRP.
After centrifuging, the sample will be stratified into a bottom portion, consisting primarily of red blood cells, a middle portion that’s the PRP, and a top portion that is platelet-poor plasma. Dr. Hooper draws up and saves the platelet- poor plasma as well, since it probably also contains some growth factors. She’ll save that for application or injection after a PRP treatment for some patients.
Dermatology presents a host of uses for PRP. In addition to application after microneedling or resurfacing and injectable aesthetic uses, PRP can also be used to treat melasma, acne scarring, and androgenetic alopecia.
The strongest data for PRP currently are for androgenetic alopecia, said Dr. Hooper, because that’s where most of the work has been done to date. Growth factors in PRP can target the dermal papillae, shortening the anagen phase. “You will improve the anagen:telogen ratio and increase hair density and thickness,” she said.
“When you talk to your hair loss patients, there are drawbacks” with home therapy such as minoxidil and finasteride, said Dr. Hooper. “Compliance is an issue. I’m a firm believer in combination treatment for hair loss.” Studies have shown increased hair thickness and moderately decreased hair loss with PRP. Anecdotally, said Dr. Hooper, hair becomes coarser, feeling fuller and thicker; one study found that about a quarter of patients reported this effect.
Through experience, Dr. Hooper’s learned some pearls for using PRP for androgenetic alopecia. Her male patients appreciate the use of a chilling device to help with pain, especially since Dr. Hooper uses a triple-needle syringe to stamp the scalp as she injects the PRP. Depending on how her patients are tolerating the procedure, she’ll follow up by injecting some platelet-poor plasma as well.
An additional pearl? “Have your patients bring a baseball cap.” Between procedure preparation, some oozing of PRP, and bleeding from injection sites, men don’t leave as well-coiffed as when they entered, she said.
Dr. Hooper has patients return four times over the course of 6 months for androgenetic alopecia, with repeat treatments about every 6 months thereafter.
Several studies have looked at using intradermal PRP for facial rejuvenation, with largely positive results. “Once again, we see consistent efficacy with no side effects,” said Dr. Hooper. She will use PRP either intradermally or topically after microneedling or fractional ablative laser resurfacing.
If it’s being used topically, Dr. Hooper will simply wipe the PRP on after the resurfacing treatment. For microneedling, “As we finish one zone, we topically apply the PRP and move on,” she said, adding that she instructs the patient not to wash her face until bedtime.
“I like injectable delivery for PRP as well,” said Dr. Hooper. She will often use it for crepey skin under the eyes as an add-on to other treatments, she said.
Her patients report that one major upside of post-resurfacing PRP is that they feel they recover more quickly. “Less erythema and less recovery time – that’s something that’s always helpful,” said Dr. Hooper. She uses the same treatment schedule for rejuvenation as for alopecia.
Some studies have shown promise for injected PRP for striae, said Dr. Hooper. She has just begun using injected PRP for striae in her practice and is encouraged by early results she’s seeing. It’s easier for patients than using multiple at-home treatments: “I think it’s just an option, they can pop in 3 times over the next few months” for some added benefit, she said.
Scanning the audience, Dr. Hooper said, “I see a lot of younger faces out there. I would challenge you to do the studies” to build evidence-based protocols for PRP in dermatology, since lack of consensus still hinders both adoption and high-quality research.
Dr. Hooper reported multiple financial relationships with pharmaceutical and cosmetic companies.

EXPERT ANALYSIS FROM ODAC 2019
Brazilian study finds oral tranexamic acid effective for facial melasma
of patients from a public dermatology clinic in Brazil.
“Our study was one of the few to compare the use of oral TA isolated against a control group using a placebo and to evaluate the results by four different methods,” wrote lead author Mariana Morais Tavares Colferai, MD, of the Universidade de Mogi das Cruzes (Brazil), and her coauthors. The study was published online in the Journal of Cosmetic Dermatology.TA is a plasmin inhibitor, first described as a treatment for melasma in 1979. It is approved in the United States for treating menorrhagia.
In the randomized, double-blind, controlled trial of 47 patients with facial melasma – 37 completed the study – participants were assigned to one of two groups: Group A received 250 mg of tranexamic acid twice daily (n = 20) while group B received a placebo twice daily (n = 17). All patients were advised to use sunscreen. Before treatment and after 12 weeks, the researchers evaluated patients with four methods: the Melasma Area Severity Index (MASI), photographic records, patient evaluation with questionnaire (MELASQoL), and colorimetry assessed via a colorimeter.
Per evaluation of all tests, melasma improved in 50% of patients in group A, compared with 5.9% of patients in group B (P less than .005). Group A saw improvements in the mean MASI score (20.9 at pretreatment vs. 10.8 after treatment, P less than .001), mean MELASQoL value (55.4 vs. 38.2, P less than .001), and colorimetry (55.0 vs. 56.1, with higher values indicating lighter pigmentation, P = .033).
The most common side effects among those who received TA were gastrointestinal effects, such as nausea and diarrhea (5%); changes in menstrual flow (10%); and headache (14%). No serious side effects were reported.
The authors acknowledged several potential limitations in their study, including a lack of intermediate evaluations between pretreatment and 12 weeks. They also noted that the photographs were dichotomously classified as either “yes for improvement” or “no for the lack of improvement or worsening,” which may “limit the accuracy of our results” for that particular method.
The tranexamic acid and placebo for the study was provided by U.SK Dermatology/Brazil. No conflicts of interest were reported.

“Our study was one of the few to compare the use of oral TA isolated against a control group using a placebo and to evaluate the results by four different methods,” wrote lead author Mariana Morais Tavares Colferai, MD, of the Universidade de Mogi das Cruzes (Brazil), and her coauthors. The study was published online in the Journal of Cosmetic Dermatology.TA is a plasmin inhibitor, first described as a treatment for melasma in 1979. It is approved in the United States for treating menorrhagia.
In the randomized, double-blind, controlled trial of 47 patients with facial melasma – 37 completed the study – participants were assigned to one of two groups: Group A received 250 mg of tranexamic acid twice daily (n = 20) while group B received a placebo twice daily (n = 17). All patients were advised to use sunscreen. Before treatment and after 12 weeks, the researchers evaluated patients with four methods: the Melasma Area Severity Index (MASI), photographic records, patient evaluation with questionnaire (MELASQoL), and colorimetry assessed via a colorimeter.
Per evaluation of all tests, melasma improved in 50% of patients in group A, compared with 5.9% of patients in group B (P less than .005). Group A saw improvements in the mean MASI score (20.9 at pretreatment vs. 10.8 after treatment, P less than .001), mean MELASQoL value (55.4 vs. 38.2, P less than .001), and colorimetry (55.0 vs. 56.1, with higher values indicating lighter pigmentation, P = .033).
The most common side effects among those who received TA were gastrointestinal effects, such as nausea and diarrhea (5%); changes in menstrual flow (10%); and headache (14%). No serious side effects were reported.
The authors acknowledged several potential limitations in their study, including a lack of intermediate evaluations between pretreatment and 12 weeks. They also noted that the photographs were dichotomously classified as either “yes for improvement” or “no for the lack of improvement or worsening,” which may “limit the accuracy of our results” for that particular method.
The tranexamic acid and placebo for the study was provided by U.SK Dermatology/Brazil. No conflicts of interest were reported.

The role of the skin microbiome in skin disease
The microbiome of the gut and skin can impact one another in health and disease. Numerous dermatologic disorders can be traced to gastrointestinal etiologic origins.1 Incorporating discussion of the latest findings on the cutaneous and gut microbiome expands our understanding of the origin of dermatologic disease. , but the gut microbiome also has effects on the skin microbiome that are just being elucidated. Although we do not yet know enough to give our patients definitive advice about probiotics, the knowledge in this field is rapidly expanding and is an exciting area to watch. Certainly, everything applied to the skin or ingested in the diet plays a role in the skin and gut microbiome. Therefore, the savvy dermatologist understands that personal care products, including cosmeceuticals, will affect the microbiome. At this point, we do not yet know what is beneficial, but we do know that diversity of organisms is important and is the preferred state as compared to having fewer types of organisms on the skin.
Acne
Acne has long been known to have a multifactorial etiologic pathway. It is increasingly thought that understanding the role of the skin (and possibly gut) microbiome in acne pathophysiology may lead to enhanced treatments.2 New gene sequencing technologies, particularly those based on recA and tly loci, are teaching us more about the anaerobic bacterium Propionibacterium acnes (now called Cutibacterium acnes).3
In 2017, Dréno et al. studied the skin microbiota in 26 subjects with mild to moderate acne. The microflora were characterized using a high‐throughput sequencing approach that targets a portion of the bacterial 16S rRNA gene. The samples were obtained before and after 28 days of treatment with erythromycin 4% or a cosmeceutical containing lipohydroxy acid, salicylic acid, linoleic acid, niacinamide, piroctone olamine, a ceramide, and thermal spring water. Upon conclusion of the study, Actinobacteria were reduced in both groups while staphylococci were reduced only in the dermocosmetic group.4 The interesting point of this study was that the cosmeceutical had a greater impact on staphylococci than did topical erythromycin, demonstrating that personal care products can have profound effects on the microbiome.
Early in 2018, Kelhälä et al. compared the impact of the systemic acne treatments isotretinoin and lymecycline on cutaneous microbiota in the cheeks, back, and axillae of mild to moderate acne patients using gene sequencing. They found that acne severity positively correlated with Propionibacterium acnes levels. P. acnes levels were decreased by both treatments, but isotretinoin resulted in a greater decrease. Increased microbiome diversity was seen on the cheek and back in all treated subjects, but diversity was highest in those treated with isotretinoin.5 The authors postulated that the diversity resulted from a decrease in P. acnes levels.

Atopic dermatitis
Atopic dermatitis (AD) is associated with dysbiosis of cutaneous microbiota and diminished diversity in microbial communities.6,7 There is also a robust epidemiologic relationship between the cutaneous and gut microbiomes and AD.8 Many studies have looked at the role of the microbiome in AD, including the role of Staphylococcus aureus, because it selectively colonizes the lesional skin of AD patients but is notably lacking on the skin of most healthy people.
In a 2017 literature review, Bjerre et al. found that while the data were not extensive, AD-affected skin was characterized by low bacterial diversity with S. aureus and Staphylococcus epidermidis more abundant. Also that year, Williams and Gallo reported on a prospective clinical trial in children that colonization by S. aureus occurred before the emergence of AD symptoms.9 In 2018, Clausen et al. reported on an observational case-control study of 45 adult healthy controls and 56 adult patients with AD between January and June 2015 to evaluate skin and nasal microbiome diversity and composition and to elucidate the relationship between disease severity and filaggrin gene mutations in AD patients. Next-generation sequencing targeting 16S ribosomal RNA was used to show that microbiome diversity was lower in the lesional skin, nonlesional skin, and nose in AD patients compared with controls. Such diversity was also found to be inversely correlated with disease severity, and microbiome composition in nonlesional AD skin was found to be associated with filaggrin gene mutations. The authors concluded that host genetics and skin microbiome may be connected in AD.10
However, the role of S. aureus in AD and the effect of its presence on microbiome diversity is still unclear. Marrs and Flohr note that the eradication of S. aureus does not appear to account for improvement in AD and increase in bacterial diversity after the use of antimicrobial and anti-inflammatory therapy.11
Rosacea
Rosacea is a chronic inflammatory skin condition long associated with Demodex mites (Demodex folliculorum and Demodex brevis).12 In rosacea-affected skin, Demodex mites are found to occur in greater density than in unaffected skin.13 Other microbiota-linked alterations have been detected on the skin and in the small intestines in cases of rosacea.14 One twin study showed that increased levels of Gordonia correlated with rosacea severity.15 A study in Korean women with rosacea demonstrated a reduction of Peptococcaceae, Methanobrevibacter, Slackia, Coprobacillus, Citrobacter (genus), and Desulfovibrio and an increased amount of Acidaminococcus, Megasphaera, and Lactobacillales in women with rosacea.16
Other studies have shown that treating bacterial overgrowth in the gut can improve rosacea.17 In my favorite recent study,18 complement appeared to affect microbial diversity and richness of the skin and the gut in mice, demonstrating that the immune system plays an important role in rosacea and the skin and gut microbiome. Certainly we have a lot to learn before we can make specific recommendations, but I feel certain that this area of research will unlock some of the mysteries of rosacea.

Conclusion
In recent years, it has become increasingly clear that the cutaneous microbiome is a factor in various skin disorders. Some authors such as Egert et al. advocate the use of pre- and probiotics, including topical microbiome transplantation therapies, to treat acne, rosacea, and AD.14 I believe that we do not yet have enough data to support this approach or predict which ones may be effective. Stay tuned for more developments.

Knee and elbow rejuvenation
The cosmetic industry improves techniques for tightening faces, hands, necks, and decolletes; meanwhile, sagging elbows and knees, once ignored, also are a visible sign of aging. Modifying techniques commonly used for the face and neck can yield significant improvements in the elbows and knees. The elbows and knees naturally have looser skin to allow for joint movement; over time, the skin over these joints is exposed to sun damage, friction, and recurrent extension and flexion, which cause skin laxity and aging.
A combination approach addressing skin texture, collagen damage, rhytides, and fat deposition is the most effective method for knee and elbow rejuvenation.
For knees and elbows with loose skin and rhytides, in-office noninvasive and minimally invasive radio-frequency and light energy treatments are helpful in increasing collagen production and tissue tightening. Similarly, microfocused ultrasound has been shown to be a safe and effective skin tightening treatment for the knees. In comparison to the face, however, the skin around the elbows and knees can be thinner and has fewer sebaceous glands. Caution should be used particularly with minimally invasive radio-frequency techniques in order to protect the epidermal skin. Often, treatments have to be repeated to give optimal results, which are not apparent until 3-6 months after the initial procedure.
For knee skin with severe laxity, a comprehensive approach using polydioxanone (PDO) or poly-l-lactic acid (PLLA) threads in both the upper thighs and circumferentially around the knees provides collagen production and tightening of the loose skin. Treatment of the upper thighs is essential in providing a vector that lifts the skin of the knees. Treatments can be repeated, with results seen after 90 days. Thread lifts of the knees and thighs are highly effective, noninvasive procedures with little to no downtime and can be used for severe skin laxity, wrinkling, and thinning of the knee skin.
Loose, roughened knee and elbow skin can also be treated with nonablative factional resurfacing, radio-frequency microneedling, or a series of monthly treatments with PLLA and hyaluronic acid fillers injected in the superficial to mid-dermis. Both fractional resurfacing and dermal filler injections help stimulate collagen production and improve both fine rhytides and dermatoheliosis.
Adipose tissue around the knees can be treated with monthly deoxycholic acid injections (for a video of this procedure, go to https://drive.google.com/file/d/1rhw-nESy15AoDhKUrc25DDjKEun7RL4i/view). The volume of injection, however, is significantly higher than that recommended in the submental area. Two to four times the volume is needed per knee over a series of 3-6 treatments, depending on the amount of fat in the knees.
Cryolipolysis is also an effective option for fat pockets around the knees; however, in my experience, it can be difficult to fit the applicators onto the area of concern appropriately unless smaller applicators are applied.
With the increasing demand for body rejuvenation techniques, providers are adapting techniques used for the face and neck to lift, tighten, thin, and sculpt the knees and elbows. A combination approach using lasers, ultrasound, fillers, threads, and cryolipolysis can be effective for these areas. Results are obtainable when repeat treatments are performed; however, one must be patient because results are not seen for 6 months or more.

A case of cold burn reported with whole-body cryotherapy
by Mackenzie O’Connor and her colleagues in the department of dermatology and cutaneous biology at Thomas Jefferson University, Philadelphia.
In the report, they describe the case of a 71-year-old man who presented with a cold burn injury a day after a WBC session. These treatments typically involve sessions of 2-5 minutes, in a chamber that is cooled down to –100°C to –140°C.
The likely cause in this case was a nozzle malfunction that caused liquid nitrogen to come in direct contact with the patient’s skin for a prolonged period of time (less than 1 minute), causing stinging and pain, followed by redness and blistering of the skin. The patient had received four WBC treatments previously for arthritis and back pain, with no adverse effects. In addition to ibuprofen, he was treated with systemic steroids, topical corticosteroids, and silver sulfadiazine cream.
Despite claims that WBC can aid muscle recovery and alleviate joint pain, and can improve skin health, and is increasingly available in spas and other sites, the Food and Drug Administration has not approved the procedure for treatment of any medical conditions, the researchers noted (JAAD Case Rep. 2019;5[1]:29-30). They also referred to a 2015 Cochrane review, which found insufficient evidence that WBC treatment is beneficial for muscle recovery in active young adult men.
