Efficacy of a Natural Topical Skin Ointment for Managing Split-Thickness Skin Graft Donor Sites: A Pilot Double-blind Randomized Controlled Trial.

OBJECTIVE: To evaluate the safety and efficacy of a new topical skin ointment with natural ingredients (aloe vera, honey, and peppermint) for dressing skin graft donor sites. DESIGN: A double-blind, placebo-controlled, randomized clinical trial. PATIENTS AND INTERVENTION: Researchers enrolled patients who were referred for split-thickness skin graft after burns or surgical wounds on the scalp or face area. For each patient, a thin layer of skin (depth, 0.04 mm; approximate size, less than 15 × 7 cm) was harvested from the thigh by a plastic surgeon with an electric or manual dermatome. The donor sites were divided and randomized to receive either natural ointment or petroleum jelly as a topical agent to dressing. Topical agents were applied on donor site wounds on days 0, 4, 7, and 14. MAIN OUTCOME MEASURES: Wound size, pain, erythema, pruritus, patient discomfort, complications, and physician satisfaction were evaluated at each visit. MAIN RESULTS: Among 28 patients, there was no significant difference between the two treatment agents regarding the rate of wound healing (P = .415), pain (P = .081), pruritus (P = .527), and patient discomfort (P = .616). The ointment was superior to petroleum jelly in reducing wound erythema (P = .001) and was associated with significantly better treatment satisfaction (P < .001). CONCLUSIONS: The natural topical ointment investigated in this study may be an acceptable alternative to petroleum jelly in caring for split-thickness donor skin graft donor site wounds to effectively promote wound healing, prevent infection and scarring, reduce pain, and comfort the patient.

Relationship Between Level of Serum 25-Hydroxyvitamin D and Risk of Squamous Cell Carcinoma in an Iranian Population.

BACKGROUND: The relationship between vitamin D and skin squamous cell carcinoma (SCC) is not well defined. OBJECTIVE: To investigate the relationship between vitamin D levels and the incidence of skin SCC for the first time in Iran. METHODS AND STUDY DESIGN: In this case-control study, 126 subjects were enrolled (63 in each group) out of referents to Razi Skin Hospital in Tehran in 2014. The risk factors for cancer gathered by self-reported questionnaires and blood samples were obtained to measure the level of 25-hydroxyvitamin D. Multivariate logistic regression was used to neutralize the effect of confounding factors. RESULTS: Cases of SCC were more likely to be in men, older than 49 years and working in an outdoor environment, and with longtime exposure to sunlight and a personal history of skin cancers. Family history of skin cancer and of cigarette smoking were not significantly related to SCC. In the SCC and control groups, 69.8% and 31.7%, respectively, had sufficient levels of vitamin D (P < 0.001). Mean level of 25-hydroxyvitamin D was 40.99 ng/mL in the SCC group and 26.34 ng/mL in the control group (P < 0.05). In the unadjusted model, the level of vitamin D as a continuous variable was positively related to SCC risk. In the adjusted model, vitamin D did not independently predict the likelihood of SCC. CONCLUSION: Vitamin D level and SCC risk are directly related, although not in an independent fashion. Indeed, this relation is severely confounded by exposure to sunlight, which was evidenced by an increased vitamin D level in the people working outside and the higher prevalence of SCC in the same population.

Comparison of topical 8-methoxypsoralen and narrowband ultraviolet B with narrowband ultraviolet B alone in treatment-resistant sites in plaque-type psoriasis: a placebo-controlled study.

BACKGROUND: Combination of topical methoxsalen and narrowband ultraviolet B (NBUVB) was shown to be more effective than NBUVB alone in treating plaque-type psoriasis. OBJECTIVE: To find out whether topical methoxsalen and NBUVB had any benefit in induction of remission on treatment-resistant plaques of psoriasis on the legs in comparison with NBUVB alone. METHODS: Ten patients were included. Two symmetric lesions with similar Psoriasis Severity Index score on the lower legs were randomly assigned to be treated with cold cream as placebo or 0.1% 8-methoxypsoralen (8MOP) cream 15 min before phototherapy with NBUVB. Phototherapy was given three times per week for up to three months. Severity scores were recorded each week and side effects were observed before each session. RESULTS: Significant decrease in the severity score was observed in both groups (P-value < 0.001), but none of the lesions cleared completely at the end of the study. The decrease of the score in the 8MOP arm was greater than the control arm; however, the difference was not significant. The only side effect was pigmentation that occurred in all of the 8MOP-treated patients after 2 weeks. CONCLUSION: We could not confirm any significant benefit of topical methoxsalen and NBUVB in comparison to NBUVB alone in treating resistant plaques of psoriasis on the legs.
