Onion extract gel versus petrolatum emollient on new surgical scars: prospective double-blinded study.

BACKGROUND: Cutaneous scars resulting from surgical procedures can be erythematous, hypertrophic, pruritic, painful, or cosmetically unacceptable. An onion extract-based topical gel (Mederma, Merz Pharmaceuticals, Greensboro, NC, USA) has been marketed as a product to improve scar appearance and texture. However, few data are available to substantiate these claims. OBJECTIVE: To compare the efficacy between the onion extract gel and a petrolatum-based emollient (Aquaphor, Beiersdorf, Inc., Wilton, CT, USA) in improving the appearance and symptoms of new surgical scars. METHODS: Twenty-four patients with new surgical wounds of at least 4 cm in length were enrolled in the study. Using a randomized, double-blinded, split-scar study design, each scar was divided into two equal portions, and each half was assigned treatment with either onion extract gel or petrolatum ointment at the time of suture removal. Each product was applied three times daily for 8 weeks, and patients were evaluated at 2, 8, and 12 weeks following initiation of treatment. A follow-up telephone interview was conducted at least 11 months postoperatively. RESULTS: Scar halves were evaluated by blinded investigators for overall cosmetic appearance, erythema, and hypertrophy. Patients also independently rated side-specific erythema, pruritus, burning, and pain. Using the paired t-test and the Wilcoxon signed rank test, we found no statistically significant difference (p < .1) between the two treatment groups in any of the outcome variables studied. CONCLUSION: Petrolatum-based topical agents constitute standard therapy in the management of postoperative wounds. In this side-by-side, randomized, double-blinded, split-scar study, the onion extract gel did not improve scar cosmesis or symptomatology when compared with a petrolatum-based ointment.

Mastitis: effect of pH, temperature, and emollients on disinfecting action of N,N-dimethyldodecanamine.

Growth inhibition of bacteria over time by N,N-dimethyldodecanamine, a tertiary alkyl amine, was studied to evaluate disinfecting action with changes in pH and temperature and with addition of emollients. Because alkyl amines have limited solubility in aqueous solutions, the effect of pH on solubility of the tertiary amine was determined. Non-growing cultures of Streptococcus agalactiae or Escherichia coli were added to sterile buffer or buffer containing the amine, and at specific intervals aliquots were removed, neutralized in a lecithin/Tween 80 quencher, and then plated to determine the number of surviving bacteria per plate. Survival curves were used to determine the effect of changing environmental conditions on antimicrobial activity. Antimicrobial activity was greater at pH 7 than at pH 8 and was least at pH 6. Increases in temperature from 20 to 40 degrees C caused a corresponding increase in antimicrobial activity. Addition of up to 10% glycerin or propylene glycol caused no significant decrease in antimicrobial activity of the tertiary amine.

Clobetasol propionate 0.05% lotion in the treatment of moderate to severe atopic dermatitis: a randomized evaluation versus clobetasol propionate emollient cream.

Atopic dermatitis (AD) is a chronic inflammatory and pruritic skin disorder marked by alternating periods of relapse and remission. This multicenter, randomized, active- and vehicle-controlled, investigator-blinded study compared the efficacy and safety of clobetasol propionate lotion to clobetasol propionate cream formulation and lotion vehicle in the treatment of moderate to severe AD. A total of 229 subjects applied treatment twice-daily for 2 weeks. Clobetasol propionate lotion was significantly more effective than its lotion vehicle at 2 weeks and comparable to the cream formulation. Clinical success after a 2-week, treatment-free follow-up period was greater in the clobetasol propionate lotion group than in the cream group. Clobetasol propionate lotion is effective, safe, well tolerated and offers a better remission profile in the treatment of moderate to severe AD as compared to clobetasol propionate emollient cream.

[Quality of life, emollients and hydrating agents].

So-called dry skin is a quite common and annoying condition. This skin may affect individuals that are otherwise healthy. It may be particularly severe and unpleasant in cases of ichthyosis, atopic dermatitis or psoriasis. The inductive effects of the environment must not be ignored. Emollients and hydrating agents for the stratum corneum can help relieve the clinical manifestations.

A clinical study on the efficacy of two commercial veterinary emollients (MicroPearls and Humilac) in the management of wintertime dry skin in dogs.

Twenty dogs with wintertime dry skin were treated with 2 commercial veterinary emollients. All dogs received weekly treatment for 4 weeks according to manufacturers' recommendations. In one-half of the dogs, treatment was initiated with MicroPearls (2 weeks) and followed with Humilac (2 weeks). This sequence was reversed for the other one-half of the dogs. MicroPearls was the superior product in 16 of the 20 dogs (80%). Side effects were rare with either product.

Tazarotene cream for the treatment of facial photodamage: a multicenter, investigator-masked, randomized, vehicle-controlled, parallel comparison of 0.01%, 0.025%, 0.05%, and 0.1% tazarotene creams with 0.05% tretinoin emollient cream applied once daily for 24 weeks.

OBJECTIVE: To assess the safety and efficacy of 4 concentrations of tazarotene cream in the treatment of facial photodamage. DESIGN: Prospective weekly multicenter, investigator-masked, randomized, parallel-group study. SETTING: University hospitals and clinical research centers. PATIENTS: Three hundred forty-nine subjects with facial photodamage. INTERVENTION: Daily topical application of tazarotene cream (0.01%, 0.025%, 0.05%, and 0.1%) compared with its vehicle and with 0.05% tretinoin emollient cream. RESULTS: Tazarotene cream and tretinoin cream significantly improved mottled hyperpigmentation and fine wrinkles. At week 24, treatment success rates based on global responses were 67% (39 of 58 subjects) with 0.1% tazarotene, 52% (30 of 58 subjects) with 0.05% tazarotene, 36% (21 of 58 subjects) with 0.025% tazarotene, 41% (24 of 59 subjects) with 0.01% tazarotene, 55% (32 of 58 subjects) with 0.05% tretinoin, and 22% (13 of 58 subjects) with vehicle. Local adverse events, although more frequent with tazarotene at higher concentrations, were generally mild to moderate. CONCLUSIONS: Tazarotene in a cream formulation is safe and is associated with positive changes in the treatment of photodamaged facial skin.

Effects of pretreatment with a urea-containing emollient on nickel allergic skin reactions.

The aim of this study was to evaluate the effect of a moisturizer containing urea on allergic contact dermatitis. Twenty-five nickel-sensitized patients and five controls (non-sensitized volunteers) applied such a moisturizer on the volar side of one forearm twice daily for 20 days, while the other forearm served as the control. After treatment with the moisturizer, patch tests with 0%, 0.5% and 2% NiSO4 in petrolatum were applied in a randomized manner on each arm. After 72 h, the skin reactions were blindly evaluated by clinical scoring and by measuring transepidermal water loss and electrical impedance. After treatment, the baseline transepidermal water loss values were lower and the baseline magnitude impedance index values were higher on the pretreated forearm. According to clinical scoring and measurements with the two physical measurement techniques, the degree of the patch test reactions was equal. All control subjects had negative nickel tests. We concluded that the skin reactivity to nickel in nickel-sensitized patients is not significantly affected by use of the urea-containing moisturizer.

Effects of some emollients on the transmission of ultraviolet.

BACKGROUND/PURPOSE: Various topical agents which can be used in combination with phototherapy may have blocking or enhancing effects. In this in vivo study, the effects of topical petrolatum, basis cream, glycerine and olive oil on the transmission of ultraviolet B (UVB) were investigated. METHODS: A phototest was performed to determine the minimal erythema dose (MED) on 32 volunteers and the test was repeated with white petrolatum, basis cream, glycerine, olive oil and sunscreen (0.3 cm3/25 cm2). The effects of each agent on MED was determined after 24 h. RESULTS: MEDs were increased with the application of white petrolatum and basis cream. However, MEDs were not changed with the application of glycerine and olive oil. CONCLUSION: The application of white petrolatum and basis cream, which have blocking effects, immediately before UVB therapy is not recommended. However, glycerine and olive oil, which does not have any effect, can be used before phototherapy.
