Portulaca oleracea, also known as purslane, has long been used in various traditional medicine systems to relieve pain and edema.¹Portulaca oleracea is a warm-climate annual plant originally found in the Middle East, North Africa, and the Indian subcontinent and now cultivated in the Arabian peninsula; Japan, where it is an abundant garden plant from spring to fall;^2,3 and throughout the world.

The use of P. oleracea, a member of the Portulacaceae family, as a vegetable as well as herbal medicine dates back several centuries.⁴ In modern times, purslane has been found to be rich in antioxidants, particularly omega-3 fatty acids, vitamins C and E, beta-carotene, melatonin, and glutathione, as well as several minerals.^5,6,7 Currently, it is considered one of the top ten most common plants in the world, and one of the most-used medical plants according to the World Health Organization.⁶ It is considered a weed in the United States, but is eaten in many parts of the world.

Antioxidant activity

Using two different assays, Uddin et al. determined in 2012 that P. oleracea cultivars exhibited significant antioxidant activity through various growth stages. In addition, the researchers suggested that purslane could provide multiple minerals as well as antioxidants in the context of nutraceutical products and functional food.⁷ Early this year, Silva et al. studied the antioxidant activity of P. oleracea leaves, flowers, and stems from two different locations in Portugal, with assays revealing significantly greater antioxidant activity in the stems of both samples compared to the leaves and flowers. However, the phenolic extracts of all three plant sections from both samples were found to protect DNA against hydroxyl radicals. The investigators concluded that their findings, particularly related to high antioxidant activity, support the potential benefits of purslane consumption to human health.⁸

A 2014 analysis of 13 collected purslane accessions revealed significant mineral content (particularly potassium, followed by nitrogen, sodium, calcium, magnesium, phosphorus, iron, zinc, and manganese) and showed that antioxidant activity was more strongly associated with ornamental as opposed to common purslane, the latter of which was richer in mineral content.⁶

Anti-inflammatory activity

In 2000, Chan et al. found that a 10% ethanolic extract of the dried leaves and stem of a P. oleracea cultivar displayed significant anti-inflammatory and analgesic properties after topical and intraperitoneal, but not oral, administration in comparison to diclofenac sodium, a synthetic drug used as active control. They added that these activities corresponded to the reputed effects of the traditional uses of the wild species.⁹

Wound healing activity

Rashed et al. reported in 2003 that a crude extract of P. oleracea accelerates wound healing. They used Mus musculus JVI-1 to show that fresh homogenized crude aerial parts of the plant topically applied on excision wound surfaces reduced wound surface areas and increased tensile strength. The best documented contraction was associated with a single dose of 50 mg, followed by two doses of 25 mg each.¹⁰

Oral lichen planus treatment

In 2010, Agha-Hosseini et al. conducted a randomized double-blind placebo-controlled 3-month study to assess the effectiveness of purslane in the treatment of oral lichen planus. Thirty-seven symptomatic patients (confirmed by biopsy) were divided into a purslane treatment group (n = 20) and a placebo group (n = 17). The investigators reported that partial to complete clinical improvement was observed in 83% of the treatment group, with no response in the remaining 17%, whereas partial improvement was seen in 17% of the placebo group, 73% had no response, and the condition was aggravated in 10% of the placebo group. No adverse side effects were reported in either group, and the researchers concluded that purslane was clinically effective in treating oral lichen planus and warrants consideration as a treatment option for the disorder.⁵

Other activities

In 2001, Radhakrishnan et al. identified several neuropharmacological actions, particularly anti-nociceptive and muscle-relaxing activity, with a range of effects on the central and peripheral nervous system observed in animal studies.¹ The betacyanins found in P. oleracea have subsequently been found to confer a protective effect against neurotoxicity, specifically, ameliorating the D-galactose-induced cognitive deficits in senescent mice.¹¹P. oleracea also has been shown to efficiently eliminate the endocrine-disrupting chemical bisphenol A from a hydroponic solution.¹²

In 2012, Yan et al. showed that three newly isolated homoisoflavonoids, known as portulacanones, and the compound 2,2’-dihydroxy-4’,6’-dimethoxychalcone selectively exhibited in vitro cytotoxic activities against four human cancer cell lines.²

Conclusions

This antioxidant-rich plant is found throughout the world and has long been associated with traditional health care. Modern research into its potential dermatologic uses is ongoing, but the evidence is relatively scarce. There are indications that the antioxidant, anti-inflammatory, and wound healing activity reportedly exhibited by purslane may be harnessed for various cutaneous applications. However, much more research is necessary to determine how extensive a role purslane may play in skin care.

As summertime approaches, opportunities for outdoor activities increase. For many of our patients, summer inspires a desire to have aesthetic procedures in preparation for outdoor events, such as weddings and vacations. We must, however, be mindful that increased sun exposure after some aesthetic procedures can mean an increased risk of complications.

The main complication we worry about with sun exposure is, of course, hyperpigmentation. The risk is low with injectable procedures such as botulinum toxin and fillers, but sun protection is still encouraged, especially in skin types III-VI. The risk increases greatly with chemical peels and laser and light-based procedures, such as intense pulsed light, vascular lasers, pigment lasers, laser hair removal, and especially nonablative and ablative resurfacing (including nonlaser resurfacing such as dermabrasion).

Sun protection should be encouraged, even with seemingly less invasive procedures, such as electrodessication. I once had a patient with type-IV skin tell me at her first visit that, years before, she had electrodessication on her face for DPN (dermatosis papulosa nigra), a procedure she had done on several occasions without complications and great results. However, she went to a party on a boat the weekend after the procedure and developed hyperpigmentation at the procedure areas, and she still had a few dark macules several years later.

At a follow-up visit, she said the doctor told her she should not have gone out on the boat and should have worn sunscreen. Of course, she was highly upset that she wasn’t advised about sun protection at the time of the procedure. This is one of several stories I’ve heard or seen of complications and postinflammatory hyperpigmentation after an aesthetic procedure, when the patients felt that the treating physician or practitioner did not counsel them about sun exposure during the consultation or treatment visit. It seems intuitive, but I’ve made it a habit to make sun protection part of my counseling routine.

In my practice, we often give patients sunscreen to apply immediately after a procedure. Specifically encouraging the use of zinc- and/or titanium-based, broad-spectrum, noncomedogenic physical blockers that are SPF 30 or higher may help reduce the risk of potential irritation or allergy and subsequent postinflammatory pigmentary alteration from chemical blocking ingredients. We provide a postprocedure handout, and the medical assistant also will counsel about sun protection when applying it to the patient or reviewing postprocedure instructions. So the patient is counseled at least three times: By me during consultation or pre-procedure, by the medical assistant post procedure, and by written instructions.

Vigorous sun protection is encouraged for at least 1 week after any aesthetic procedure (and longer if the downtime is longer or if multiple treatments are required). Some practices also use antioxidant serums to reduce free radicals, encourage healing, and reduce the risk of hyperpigmentation after procedures. Wide-brimmed hats also are encouraged, particularly after resurfacing or photodynamic therapy (PDT). We give patients sun-protective hats when they leave our office after PDT. We counsel them to practice vigorous sun protection for at least 1 week and to avoid sitting by a window for 48 hours after the procedure so as to not reactivate the levulan.

Delaying more high-risk procedures, such as laser treatments, until after the summer months may be appropriate if sun cannot be avoided to mitigate the risk of complications. If a patient comes to the office for a laser procedure and is visibly more tan than at the time of the last treatment, I will counsel about risks, adjust the settings appropriately, or even delay the treatment altogether to a time when the tan has faded. This is particularly important for lasers and light treatments for which melanin is the target chromosphere, such as intense pulsed light and laser hair removal. Although UV exposure is more intense in the summer, in our practice in Southern California we follow these principles year-round for the safety of our patients.

CHICAGO – Adult survivors of childhood burns have significantly higher rates of Axis I mental and physical disorders years after their injury, a population-based study shows.

“We think it is really important to screen for, identify, and treat these illnesses not only in that acute period and shortly after the burn injury, but well into adulthood,” study author James Stone said at the annual meeting of the American Burn Association.

Patrice Wendling/Frontline Medical News

He reported on 745 adult burn survivors identified using administrative data from a regional pediatric burn center registry in Manitoba, Canada, who were matched 1:5 with 3,725 controls from the general Manitoba population based on age, sex, and geographic location. The burn survivors had an average age of 5.9 years at the time of burn injury, burns involved an average 12% of total body surface area, and 65% of burn survivors were male. The average follow-up was nearly 15 years (range 2.8-24.7 years).

In unadjusted univariate analysis, adult survivors had significantly higher rates than matched controls for any lifetime physical disorder (rate ratio, 1.17), arthritis (RR, 1.23), cancer (RR, 1.94), diabetes (RR, 1.69), fractures (RR, 1.45), and total respiratory morbidity (RR, 1.15).

After adjustment for gender, geography, and income, any physical disorder (RR, 1.15; P value < .01), arthritis (RR, 1.24; P < .01), fractures (RR, 1.37; P .001), and total respiratory morbidity (RR, 1.13; P < .05) remained significant, Mr. Stone, from the University of Manitoba, Winnipeg, Canada, reported.

Further, 81% of burn survivors had a lifetime physical illness compared with 69% of controls.

“The fact that 81% of our burn cohort was diagnosed with a physical illness is definitely concerning,” he said. “We hypothesize that the prolonged hyperinflammatory and hypermetabolic state that has been previously reported makes these individuals more susceptible to these illnesses down the road.”

The burn cohort also had significantly higher unadjusted rate ratios for any Axis 1 mental disorder (RR, 1.62), major depressive disorder (RR, 1.64), anxiety (RR, 1.57), substance abuse (RR, 2.86), and suicide attempts (RR, 5.00).

All disorders remained statistically significant after adjustment with rate ratios of 1.54 (P < .001), 1.54 (P < .001), 1.50 (P < .001), 2.35 (P < .001), and 4.33 (P < .01), respectively.

The high rates of substance abuse and suicide attempts are consistent with previous clinical interview studies, but are still cause for great concern, Mr. Stone said.

The risk for any mental or physical disorder was not significantly impacted by burn location or by burns that affected more than 30% of total body surface area. Age older than 5 years at the time of the burn significantly increased the risk of any mental disorder (relative risk, 1.92; P < .001).

Limitations of the study include the potential for bias because the data relied on individuals presenting to physicians, discrepancies between ICD codes for physician billings and hospital claims, and some survivors may have moved out of the province, Mr. Stone said. The study, however, had a sample size three times greater than the next largest study of its kind, and importantly, matched burn patients to the general population.

CHICAGO – Adult survivors of childhood burns have significantly higher rates of Axis I mental and physical disorders years after their injury, a population-based study shows.

“We think it is really important to screen for, identify, and treat these illnesses not only in that acute period and shortly after the burn injury, but well into adulthood,” study author James Stone said at the annual meeting of the American Burn Association.

He reported on 745 adult burn survivors identified using administrative data from a regional pediatric burn center registry in Manitoba, Canada, who were matched 1:5 with 3,725 controls from the general Manitoba population based on age, sex, and geographic location. The burn survivors had an average age of 5.9 years at the time of burn injury, burns involved an average 12% of total body surface area, and 65% of burn survivors were male. The average follow-up was nearly 15 years (range 2.8-24.7 years).

In the United States, the cosmetic use of botulinum toxin type A (BTX-A) has continued to grow over the last 15 years, according to multispecialty data recently released by the American Society for Aesthetic Plastic Surgery. During these years, many of our patients, if not ourselves, have undergone treatment faithfully every 3 to 6 months to combat the signs of aging. Subsequently, with the monitoring of adverse events (AEs), the US Food and Drug Administration has issued a black box warning that covers serious side effects—respiratory compromise and death—associated with treatment, yet most of what is listed in the black box warning pertains to medical use rather than cosmetic use. However, with the ever-growing indications for BTX-A, we must be cognizant of the fact that our patients may be receiving concomitant treatment with BTX-A for medical conditions (eg, migraines, hyperhidrosis, achalasia, dysphonia, dystonia, strabismus) by other specialists. Thus, there is a need to understand the potential side effects associated with BTX-A treatments and long-term consequences.

In a January 21 article published online in Pharmacology Yiannakopoulou looked at national monitoring programs through the US Food and Drug Administration and the Danish Medicines Agency. Many of the AEs reported were related to medical use of BTX-A, including anaphylaxis, death, generalized weakness, and dysphagia. Serious AEs related to the cosmetic use of BTX-A included thyroid eye disease, sarcoidal granuloma, pseudoaneurysm of the frontal branch of the superior temporal artery, and severe respiratory failure. Additionally, a patient receiving BTX-A for palmar and axillary hyperhidrosis developed botulinumlike generalized weakness. Upon review of epidemiological studies, the incidence and types of AEs were covered. The vast majority of these events were related to the medical use of BTX-A, which could stem from the lack of long-term studies on cosmetic patients and the lack of reporting of many AEs. The author summarized that minimizing potential AEs relies on proper injection technique, proper storage of the medication, proper dosing, and thorough knowledge of the anatomy.

What’s the issue?

Botulinum toxin type A remains one of the most gratifying treatments for both physicians and patients alike. However, with the potential for abuse, as in the case of the recent fake Botox Cosmetic that has shown up on the market in the United States), we must remain vigilant for AEs. Furthermore, we must continue to emphasize to patients that it is a medical treatment and deserves all the attention and respect we give to other medical interventions. However, as the Yiannakopoulou review has shown, proper injection techniques have a low rate of AEs in the cosmetic use of BTX-A. Have you seen an increase in the number of cosmetic BTX-A patients receiving concomitant treatments with BTX-A for medical conditions? If so, how do you manage them?
