RESUMO

BACKGROUND: Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) is a reliable treatment for actinic keratosis (AK), but its effect needs to be enhanced in thick lesions. Plum-blossom needle is a traditional Chinese cost-effective instrument for enhancing the transdermal delivery of ALA. However, whether it could improve the efficacy of AK treatment has not yet been investigated. OBJECTIVE: To compare the efficacy and safety of plum-blossom needle-assisted PDT in facial AK in the Chinese population. METHODS: In this multicenter, prospective study, a total of 142 patients with AKs (grades I-III) were randomized into the plum-blossom needle-assisted PDT group (P-PDT) and control PDT group (C-PDT). In the P-PDT group, each AK lesion was tapped vertically by a plum-blossom needle before the application of 10% ALA cream. In the C-PDT group, each lesion was only wiped with regular saline before ALA cream incubation. Then, 3 hours later, all the lesions were irradiated with light-emitting diode (LED) at a wavelength of 630 nm. PDT was performed once every 2 weeks until all lesion patients achieved complete remission or completed six sessions. The efficacy (lesion response) and safety (pain scale and adverse events) in both groups were evaluated before each treatment and at every follow-up visit at 3-month intervals until 12 months. RESULTS: In the P-PDT and C-PDT groups, the clearance rates for all AK lesions after the first treatment were 57.9% and 48.0%, respectively (P < 0.05). For grade I AK lesions, the clearance rates were 56.5% and 50.4%, respectively (P = 0.34). For grade II AK lesions, the clearance rates were 58.0% and 48.9%, respectively (P = 0.1). For grade III AK lesions, the clearance rates were 59.0% and 44.2%, respectively (P < 0.05). Moreover, grade III AK lesions in the P-PDT group required fewer treatment sessions (P < 0.05). There was no significant difference in the pain score between the two groups (P = 0.752). CONCLUSION: Plum-blossom needle tapping may enhance the efficacy of ALA-PDT by facilitating ALA delivery in the treatment of AK.

RESUMO

BACKGROUND: Hospitalized preterm infants with compromised skin barrier function treated topically with sunflower seed oil (SSO) have shown reductions in sepsis and neonatal mortality rate (NMR). Mustard oil and products commonly used in high-mortality settings may possibly harm skin barrier integrity and enhance risk of infection and mortality in newborn infants. We hypothesized that SSO therapy may reduce NMR in such settings. METHODS AND FINDINGS: This was a population-based, cluster randomized, controlled trial in 276 clusters in rural Uttar Pradesh, India. All newborn infants identified through population-based surveillance in the study clusters within 7 days of delivery were enrolled from November 2014 to October 2016. Exclusive, 3 times daily, gentle applications of 10 ml of SSO to newborn infants by families throughout the neonatal period were recommended in intervention clusters (n = 138 clusters); infants in comparison clusters (n = 138 clusters) received usual care, such as massage practice typically with mustard oil. Primary analysis was by intention-to-treat with NMR and post-24-hour NMR as the primary outcomes. Secondary analysis included per-protocol analysis and subgroup analyses for NMR. Regression analysis was adjusted for caste, first-visit weight, delivery attendant, gravidity, maternal age, maternal education, sex of the infant, and multiple births. We enrolled 13,478 (52.2% male, mean weight: 2,575.0 grams ± standard deviation [SD] 521.0) and 13,109 (52.0% male, mean weight: 2,607.0 grams ± SD 509.0) newborn infants in the intervention and comparison clusters, respectively. We found no overall difference in NMR in the intervention versus the comparison clusters [adjusted odds ratio (aOR) 0.96, 95% confidence interval (CI) 0.84 to 1.11, p = 0.61]. Acceptance of SSO in the intervention arm was high at 89.3%, but adherence to exclusive applications of SSO was 30.4%. Per-protocol analysis showed a significant 58% (95% CI 42% to 69%, p < 0.01) reduction in mortality among infants in the intervention group who were treated exclusively with SSO as intended versus infants in the comparison group who received exclusive applications of mustard oil. A significant 52% (95% CI 12% to 74%, p = 0.02) reduction in NMR was observed in the subgroup of infants weighing ≤1,500 g (n = 589); there were no statistically significant differences in other prespecified subgroup comparisons by low birth weight (LBW), birthplace, and wealth. No severe adverse events (SAEs) were attributable to the intervention. The study was limited by inability to mask allocation to study workers or participants and by measurement of emollient use based on caregiver responses and not actual observation. CONCLUSIONS: In this trial, we observed that promotion of SSO therapy universally for all newborn infants was not effective in reducing NMR. However, this result may not necessarily establish equivalence between SSO and mustard oil massage in light of our secondary findings. Mortality reduction in the subgroup of infants ≤1,500 g was consistent with previous hospital-based efficacy studies, potentially extending the applicability of emollient therapy in very low-birth-weight (VLBW) infants along the facility-community continuum. Further research is recommended to develop and evaluate therapeutic regimens and continuum of care delivery strategies for emollient therapy for newborn infants at highest risk of compromised skin barrier function.

RESUMO

Plant tissue culture holds immense potential for the production of secondary metabolites with various physiological functions. We recently established a plant tissue culture system capable of producing secondary metabolites from Aster yomena. This study aimed to uncover the mechanisms underlying the potential therapeutic effects of Aster yomena callus pellet extract (AYC-P-E) on photoaging-induced skin pigmentation. Excessive melanogenesis was induced in B16F10 melanoma cells using α-melanocyte stimulating hormone (α-MSH). The effects of AYC-P-E treatment on melanin biosynthesis inducers and melanin synthesis inhibition were assessed. Based on the results, a clinical study was conducted in subjects with skin pigmentation. AYC-P-E inhibited melanogenesis in α-MSH-treated B16F10 cells, accompanied by decreased mRNA and protein expression of melanin biosynthesis inducers, including cyclic AMP response element-binding protein (CREB), tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase related protein-1 (TRP-1), and TRP-2. This anti-melanogenic effect was mediated by mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) and protein kinase B (AKT) phosphorylation. Treatment of subjects with skin pigmentation with AYC-P-E-containing cream formulations resulted in 3.33%, 7.06%, and 8.68% improvement in the melanin levels at 2, 4, and 8 weeks, respectively. Our findings suggest that AYC-P-E inhibits excessive melanogenesis by activating MEK/ERK and AKT signaling, potentiating its cosmetic applications in hyperpigmentation treatment.

RESUMO

BACKGROUND: Impetigo, a highly contagious bacterial skin infection commonly occurring in young children, but adults may also be affected. The superficial skin infection is mainly caused by Staphylococcus aureus (S. aureus) and less frequently by Streptococcus pyogenes (S. pyogenes). Antimicrobial resistance has become a worldwide concern and needs to be addressed when selecting treatment for impetigo patients. An evidence-based impetigo treatment algorithm was developed to address the treatment of impetigo for pediatric and adult populations. METHODS: An international panel of pediatric dermatologists, dermatologists, pediatricians, and pediatric infectious disease specialists employed a modified Delphi technique to develop the impetigo treatment algorithm. Treatment recommendations were evidence-based, taking into account antimicrobial stewardship and the increasing resistance to oral and topical antibiotics. RESULTS: The algorithm includes education and prevention of impetigo, diagnosis and classification, treatment measures, and follow-up and distinguishes between localized and widespread or epidemic outbreaks of impetigo. The panel adopted the definition of localized impetigo of fewer than ten lesions and smaller than 36 cm2 area affected in patients of two months and up with no compromised immune status. Resistance to oral and topical antibiotics prescribed for the treatment of impetigo such as mupirocin, retapamulin, fusidic acid, have been widely reported. CONCLUSIONS: When prescribing antibiotics, it is essential to know the local trends in antibiotic resistance. Ozenoxacin cream 1% is highly effective against S. pyogenes and S. aureus, including methycyllin-susceptible and resistant strains (MRSA), and may be a suitable option for localized impetigo.J Drugs Dermatol. 2021;20(2):134-142. doi:10.36849/JDD.5475 THIS ARTICLE HAD BEEN MADE AVAILABLE FREE OF CHARGE.

RESUMO

BACKGROUND: Neck/shoulder, sudden pain, or muscular pain (not associated to structural or bone/joints components), due to fascial or muscular strain is common in active subjects, in non-professional athletes and sports performers. The aim of this supplement registry was the evaluation of a cream based on natural, active ingredients for topical application in supporting the improvement of pain and improving head/neck mobility, possibly minimizing the use of systemic drugs. METHODS: The cream includes standardized active ingredients of natural origin as an extract of Harpagophytum procumbes, an extract from Boswellia serrata, a CO2 extract of ginger and escin. Subjects were divided into three groups, all using the standard management (SM) in combination with the Sport Cream or in addition to Flector (diclofenac) patch. RESULTS: The groups were comparable and homogeneous at the baseline. No side effects or skin tolerability issues were observed with the Sport Cream nor with the SM or diclofenac patches. Subjects receiving sport cream + SM reported a significant improvement in pain, stiffness, altered mobility and altered working capacity, with a reduced need for rescue medication (diclofenac) compared to subjects in the other two groups. CONCLUSIONS: Finally, subjects receiving sport cream + SM reported a more remarkable decrease in skin temperature in the affected area associated to an improvement in clinical symptoms.

RESUMO

Vitiligo pathophysiology is mediated by antigen-specific cytotoxic T cells. Environmental stressors cause susceptible melanocytes to secrete damage-associated molecular patterns (DAMPs). DAMPs are recognized by receptors such as the endocytic low-density lipoprotein receptor-related protein (LRP1/CD91), expressed in antigen-presenting cells, which activate self-reactive CD8+ T cells, leading to melanocyte destruction. Within this response, interferon gamma triggers production of cytokine CXCL10, recruiting more activated T cells causing further melanocytic damage. We hypothesized that expression of LRP1/CD91 was higher in vitiligo patients compared to non-vitiligo individuals. And further that levels/expression of CXCL10 in plasma were linked to disease severity. We enrolled forty individuals in this study: 18 patients with vitiligo and 22 healthy volunteers. We assessed LRP1/CD91 expression and plasma CXCL10 in patients with vitiligo and healthy volunteers. Additionally, vitiligo patients received combined treatment for 16 weeks following which the said parameters were reassessed. Vitiligo Area Scoring Index was calculated before and after treatment for these patients. Analysis of LRP1/CD91 MFI values in monocytes from vitiligo patients showed high surface levels of LRP1/CD91 than from healthy volunteers (10.50 ± 0.77 vs. 6.55 ± 0.77 MFI units, p < 0.001). This expression did not change after treatment. Plasma levels of CXCL10 were higher in vitiligo patients than healthy volunteers (93.78 ± 7.73 vs. 40.17 ± 6.25 pg/ml). The patients with a good clinical response to treatment had a parallel reduction in plasma CXCL10 levels (105.8 ± 18.44 vs. 66.13 ± 4.87 pg/ml) before and after treatment. LRP1/CD91 expression may reflect susceptibility to vitiligo. Plasma levels of CXCL10 can represent a biomarker for monitoring treatment response. LRP1 and CXCL10 may represent therapeutic targets.

RESUMO

This retrospective study assessed the efficacy and safety of 1% topical clotrimazole cream for the treatment of patients with tinea cruris (TC).We included 86 patients with confirmed TC for the presence of fungal hyphae. Of those, 43 patients received 1% topical clotrimazole cream for a total of 4 consecutive weeks, and were assigned to an experimental group. The other 43 patients underwent 1% topical butenafine cream for a total of 2 consecutive weeks, and were allocated to a control group. The efficacy and safety were measured and analyzed after 4 weeks treatment.After treatment, patients in both groups achieved better improvements in erythema (P < .01), scaling (P < .01), itching (P < .01), and KOH-negative results (P < .01), compared with those in patients before the treatment. However, there were not significant differences in erythema (P = .61), scaling (P = .57), itching (P = .47), and KOH-negative results (P = .67) between 2 groups. In addition, no treatment-related adverse events were recorded in both groups.Both 1% topical clotrimazole and butenafine cream are found to be effective and safe for patients with TC. However, there is not significant difference in efficacy and safety between two groups.

RESUMO

BACKGROUND: Hand-foot skin reaction (HFSR) is the most common adverse event during sorafenib treatment in patients with hepatocellular carcinoma (HCC). In the present study, we aimed to investigate the role of urea cream in the prevention of HFSR or amelioration of HFSR severity. PATIENTS AND METHODS: Patients with HCC were treated with either placebo cream or urea cream for 12 weeks concomitantly with sorafenib treatment. HFSR development, the Hand-Foot Skin Reaction and Quality of Life (HF-QoL) questionnaire score, and adverse events were assessed at 2, 4, 8 and 12 weeks. RESULTS: Of the 288 patients, 247 patients, with 117 patients in the placebo control group and 130 patients in the urea cream group, were analysed. The urea cream group showed a trend towards a lower cumulative incidence of any-grade HFSR (log-rank, P = 0.247) and severe HFSR of grade II or higher (log-rank, P = 0.394) without statistical significance. In the incidence by time point, the incidence of severe HFSR of grade II or higher was significantly lower in the urea cream group than in the placebo control group at 2 weeks (13.8% versus 23.9%, P = 0.042). The urea cream group showed a significantly better HF-QoL questionnaire score than the placebo control group (11.8 versus 19.7, P = 0.014) at 12 weeks. CONCLUSIONS: Treatment with urea cream showed a lower incidence of severe sorafenib-induced HFSR at 2 weeks and reduced the tendency of HFSR development in HCC patients. Therefore, treatment with urea cream may be considered for prophylaxis or improvement of HFSR grade in HCC patients treated with sorafenib. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03212625).

RESUMO

Colloidal oatmeal has a long-standing history in the treatment of dermatologic disease. It is composed of various phytochemicals, which contribute to its wide-ranging function and clinical use. It has various mechanisms of action including direct anti-inflammatory, anti-pruritic, anti-oxidant, anti-fungal, pre-biotic, barrier repair properties, and beneficial effects on skin pH. These have been shown to be of particular benefit in the treatment of atopic dermatitis. In Part 1 of this two-part series, we will explore the history of colloidal oatmeal, basic science, mechanism of action, and clinical efficacy in the treatment of atopic dermatitis.

RESUMO

Skin health is vital for a healthy body. Herbal remedies have long been used for skin care, and their global use has tremendously increased over the past three decades. Although cellulite is seen as a normal condition by the medical community, it is considered a serious cosmetic concern for most affected women. Many topical anti-cellulite creams are available on the market, but unfortunately, their efficacy has not been proven scientifically. Microneedles (MNs) represent a new approach to enhance the permeation of loaded medication through the skin. In this study, the anti-cellulite effects of Vitex agnus-castus and Tamarindus indica extracts were compared using safe and effective polymeric MNs. This delivery system offers a painless alternative to the combined treatment strategy of microneedling devices and anti-cellulite products. The selected standardized extracts were evaluated for their mineral, phenolic and flavonoid contents, which are correlated to a promising antioxidant effect, as demonstrated by an in vitro radical scavenging activity assay. 3D-printing techniques were chosen for fabrication of a micromold, which is inexpensive for mass production. To ensure that MNs were sufficiently strong to perforate the skin without breaking, axial failure force was measured using a micro-mechanical test machine. The anticellulite effects of MNs were assessed using an in vivo diet-induced obesity guinea pig model. Skin properties, histopathology and inflammatory markers were examined. MNs loaded with plant extracts were statistically comparable in normalizing the oxidative state and reducing inflammation, while myeloperoxidase levels were more significantly reduced by T. indica than by V. agnus-castus. This novel delivery system opens the door for new transdermal strategies for cellulite management.

RESUMO

BACKGROUND: Pharmacotherapy for allergic rhinitis (AR) still remains unsatisfying regarding its effect and safety. Barrier protection measures may be a good choice for the patients with AR. OBJECTIVE: To assess the efficacy and safety of barrier protection measures in the treatment of AR. METHODS: We selected relevant randomized controlled trials published between January 1, 1990, and February 20, 2019, by searching Embase, PubMed, Cochrane, Web of Knowledge, and ClinicalTrials.gov. The primary outcome for this analysis was rhinitis symptom scores, overall quality of life, nasal peak inspiratory flow (NPIF), and adverse events. Differences were expressed as weighted mean difference (WMD) with 95% confidence intervals (CIs) for continuous outcomes. Statistical heterogeneity across trials was assessed with the statistic (P < .1) and the I2 statistic. RESULTS: Fifteen RCTs (with data for 1154 participants) satisfied our inclusion criteria. The types of barrier protection measures comprised cellulose, pollen blocker cream, microemulsion, and nasal filter. To reduce the potential risk of bias and heterogeneity, we carried out subgroup analysis according to different types of barrier protection measures (cellulose: WMD = -2.18, 95% CI, -3.01 to -1.35, P < .00001; pollen blocker cream: WMD = -4.55, 95% CI, -6.10 to -3.00, P < .00001; microemulsion: WMD = -0.22, 95% CI, -0.42 to -0.03, P = .03). Findings from our meta-analysis show that, compared with placebo, barrier protection measures can yield improved symptomatic control for AR, with no increase in adverse events. Furthermore, barrier protection measures can improve the quality of life and NPIF. CONCLUSION: Although further studies are still needed, our findings clearly lend support to barrier protection measures as a safe and efficacious option for the treatment of AR patients.

RESUMO

BACKGROUND: Pruritus is a sensation that leads to the desire to scratch; its origin is unknown in 8% to 15% of affected patients. The prevalence of chronic pruritus of unknown origin (CPUO) in individuals with generalised pruritus ranges from 3.6% to 44.5%, with highest prevalence among the elderly. When the origin of pruritus is known, its management may be straightforward if an effective treatment for the causal disease is available. Treatment of CPUO is particularly difficult due to its unknown pathophysiology. OBJECTIVES: To assess the effects of interventions for CPUO in adults and children. SEARCH METHODS: We searched the following up to July 2019: Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and trials registries. We checked the reference lists of included studies for additional references to relevant trials. SELECTION CRITERIA: We sought to include randomised controlled trials and quasi-randomised controlled trials that assessed interventions for CPUO, as defined in category VI ('Other pruritus of undetermined origin, or chronic pruritus of unknown origin') of the International Forum for the Study of Itch (IFSI) classification, in children and adults. Eligible interventions were non-pharmacological or topical or systemic pharmacological interventions, and eligible comparators were another active treatment, placebo, sham procedures, or no treatment or equivalent (e.g. waiting list). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Our primary outcomes were 'Patient- or parent-reported pruritus intensity' and 'Adverse events'. Our secondary outcomes were 'Health-related quality of life', 'Sleep disturbances', 'Depression', and 'Patient satisfaction'. We used GRADE to assess the certainty of evidence. MAIN RESULTS: We found there was an absence of evidence for the main interventions of interest: emollient creams, cooling lotions, topical corticosteroids, topical antidepressants, systemic antihistamines, systemic antidepressants, systemic anticonvulsants, and phototherapy. We included one study with 257 randomised (253 analysed) participants, aged 18 to 65 years; 60.6% were female. This study investigated the safety and efficacy of three different doses of oral serlopitant (5 mg, 1 mg, and 0.25 mg, once daily for six weeks) compared to placebo for severe chronic pruritus; 25 US centres participated (clinical research centres and universities). All outcomes were measured at the end of treatment (six weeks from baseline), except adverse events, which were monitored throughout. A pharmaceutical company funded this study. Fifty-five per cent of participants suffered from CPUO, and approximately 45% presented a dermatological diagnosis (atopic dermatitis/eczema 37.3%, psoriasis 6.7%, acne 3.6%, among other diagnoses). We unsuccessfully attempted to retrieve outcome data from study authors for the subgroup of participants with CPUO. Participants had pruritus for six weeks or longer. Total study duration was 10 weeks. Participants who received serlopitant 5 mg may have a greater rate of relief of patient-reported pruritus intensity as measured by the visual analogue scale (VAS; a reduction in VAS score indicates improvement) compared to placebo (126 participants, risk ratio (RR) 2.06, 95% confidence interval (CI) 1.27 to 3.35; low-certainty evidence). We are uncertain of the effects of serlopitant 5 mg compared to placebo on the following outcomes due to very low-certainty evidence: adverse events (127 participants; RR 1.48, 95% CI 0.87 to 2.50); health-related quality of life (as measured by the Dermatology Life Quality Index (DLQI); a higher score indicates greater impairment; 127 participants; mean difference (MD) -4.20, 95% CI -11.68 to 3.28); and sleep disturbances (people with insomnia measured by the Pittsburgh Sleep Symptom Questionnaire-Insomnia (PSSQ-I), a dichotomous measure; 128 participants; RR 0.49, 95% CI 0.24 to 1.01). Participants who received serlopitant 1 mg may have a greater rate of relief of patient-reported pruritus intensity as measured by VAS compared to placebo; however, the 95% CI indicates that there may also be little to no difference between groups (126 participants; RR 1.50, 95% CI 0.89 to 2.54; low-certainty evidence). We are uncertain of the effects of serlopitant 1 mg compared to placebo on the following outcomes due to very low-certainty evidence: adverse events (128 participants; RR 1.45, 95% CI 0.86 to 2.47); health-related quality of life (DLQI; 128 participants; MD -6.90, 95% CI -14.38 to 0.58); and sleep disturbances (PSSQ-I; 128 participants; RR 0.38, 95% CI 0.17 to 0.84). Participants who received serlopitant 0.25 mg may have a greater rate of relief of patient-reported pruritus intensity as measured by VAS compared to placebo; however, the 95% CI indicates that there may also be little to no difference between groups (127 participants; RR 1.66, 95% CI 1.00 to 2.77; low-certainty evidence). We are uncertain of the effects of serlopitant 0.25 mg compared to placebo on the following outcomes due to very low-certainty evidence: adverse events (127 participants; RR 1.29, 95% CI 0.75 to 2.24); health-related quality of life (DLQI; 127 participants; MD -5.70, 95% CI -13.18 to 1.78); and sleep disturbances (PSSQ-I; 127 participants; RR 0.60, 95% CI 0.31 to 1.17). The most commonly reported adverse events were somnolence, diarrhoea, headache, and nasopharyngitis, among others. Our included study did not measure depression or patient satisfaction. We downgraded the certainty of evidence for all outcomes due to indirectness (only 55% of study participants had CPUO) and imprecision. We downgraded outcomes other than patient-reported pruritus intensity a further level due to concerns regarding risk of bias in selection of the reported result and some concerns with risk of bias due to missing outcome data (sleep disturbances only). We deemed risk of bias to be generally low. AUTHORS' CONCLUSIONS: We found lack of evidence to address our review question: for most of our interventions of interest, we found no eligible studies. The neurokinin 1 receptor (NK1R) antagonist serlopitant was the only intervention that we could assess. One study provided low-certainty evidence suggesting that serlopitant may reduce pruritus intensity when compared with placebo. We are uncertain of the effects of serlopitant on other outcomes, as certainty of the evidence is very low. More studies with larger sample sizes, focused on patients with CPUO, are needed. Healthcare professionals, patients, and other stakeholders may have to rely on indirect evidence related to other forms of chronic pruritus when deciding between the main interventions currently used for this condition.

RESUMO

OBJECTIVE: This study examined the effects of treatment with Phyllanthus amarus nanoparticle gel applied by phonophoresis (PP) and ultrasound therapy (UT) in patients with symptomatic knee osteoarthritis (OA) using a randomized, double-blind, controlled trial. METHODS: Patients with knee OA (n = 40; mean age ±â€¯SD, 64.30 ±â€¯9.71 years), who had visual analogue scale (VAS) scores for knee pain intensity of 68.00 ±â€¯9.58 (UT group) and 71.00 ±â€¯8.74 (PP group, respectively) before treatment, were randomly allocated into two groups. Both groups were treated with an ultrasound program in continuous mode, 1.0 W/cm2, 10 min per session, for 10 sessions. Nanoparticles of P. amarus were used in the PP group, whereas a nondrug coupling gel was used in the UT group. The 6-min walk test (6-MWT) was performed to evaluate functional capacity. The VAS and the 6-MWT were evaluated before and after 10 treatment sessions in both groups using a double-blind procedure. RESULTS: VAS and 6-MWT showed significant improvement after treatment in both groups (p < 0.05). The PP group showed more significant effects than the UT group, in terms of both reducing the VAS pain score (p < 0.05) and improving 6-MWT (p < 0.05). CONCLUSIONS: PP is suggested as an effective method for the treatment of symptomatic knee OA for reducing pain and improving functional capacity.

RESUMO

Alopecia areata is a chronic inflammatory disease that characterized by round or oval patches of non-scarring hair loss. From the past, Urginea maritima (white squill) was used for the treatment of hair loss in Iranian traditional medicine. We aimed the comparison of Clobetasol lotion and squill extract efficacy in treatment of alopecia areata in a randomized, double-blind clinical trial. The 42 patients were randomized into two groups. Both groups received topical squill and clobetasol lotion twice daily lotion for 12 weeks. Clinical evaluation included size of patches (using 1×1 cm2 schablone), total number of grown hair and number of terminal hair was performed every 2 weeks. Re-growth of terminal coarse hairs was evaluated using a semi-quantitative regrowth score (RGS) (0: no regrowth, 1: growth of <25%, 2: growth of 25-50%, 3: growth of 51-75%, 4: growth of >75%). There were significant differences between RGS4 in two groups after 2- and 3-month treatment (P<0.05). At the end of follow-up period, the mean hair growth rates increased significantly from 6.5 to 11.3 in squill group (P = 0.031) and it improved significantly from 10.3 to 17.9 in clobetasol group (P = 0.001). There were no significant differences between mean hair growth rates in two groups after 3-month treatment (P = 0.969). The lotion 2% of U. maritima bulbs extract showed good effect in 45% patients with patchy alopecia areata and showed moderate effect on re-growth of terminal hairs.

RESUMO

Introduction: The aim of this study was to investigate the effects of a topical mucoadhesive formulation with Curcuma longa L. extract (MFC) on oral wound healing. Methods: Seventy-two Wistar rats were randomly assigned to 3 groups: Control, Vehicle, and MFC. Traumatic ulcers were made on the dorsum of the tongue with a 3-mm diameter punch. Vehicle and MFC groups received application of the products twice a day, while animals in the control group were cared for in identical conditions but received no product application. Six rats in each group were euthanized at days 3, 5, 10, and 14. Percentage of repair was calculated based on wound area. HE-stained histological sections were obtained for semi-quantitative analysis of re-epithelization and inflammation. Results: Clinical findings revealed that at days 3 and 5, animals from the MFC group exhibited a significantly higher percentage of wound repair. At day 5, animals from this group also demonstrated a significant increase in the degree of re-epithelization and inflammation. Conclusions: MFC is capable of accelerating oral wound repair in an in vivo model by modulating the inflammatory process and stimulating epithelial proliferation. (AU)

RESUMO

The skin is the largest organ in the body, providing an effective barrier against excessive fluid loss and invasion from bacteria, but the barrier function of the skin can be lost when it is damaged by prolonged contact with moisture. Moisture-associated skin damage can be caused by prolonged exposure to perspiration, urine or faeces, wound exudate or stomal output. Prevention and treatment of moisture-associated skin damage involves application of skin protectants, but there is a wide range of these products available to nursing staff, and clinical decision making is hampered by a lack of robust comparative evidence. Medihoney® Barrier Cream may be used for a number of indications related to moisture-associated skin damage, including incontinence-associated dermatitis. The use of Medihoney Barrier Cream has been shown to lower pruritis complaints associated with intertrigo, and promotes patient comfort.

RESUMO

The anti-inflammatory properties of the topical herbal composition VEL-091604 with gentian root, licorice root, and willow bark extract were assessed in a randomized, prospective, placebo-controlled, double-blind ultraviolet (UV)-erythema test study with 42 healthy volunteers in comparison to 1% hydrocortisone acetate. The efficacy and tolerability of VEL-091604 cream 2 times daily over 2 wk was evaluated in an open-label, prospective proof of concept study in 10 subjects with atopic dermatitis using a lesional SCORAD severity score. In the UV-erythema test VEL-091604 cream significantly reduced inflammation compared to placebo and was as effective as 1% hydrocortisone acetate. The clinical study with atopic subjects revealed a significant and rapid reduction of the lesional SCORAD severity score in the test areas after 1 and 2 wk. No adverse events were recorded. It is concluded that the herbal cream VEL-091604 with licorice root, willow bark, and gentian root extract display anti-inflammatory properties in vivo. It is a promising new treatment option for atopic dermatitis that warrants further investigation in controlled studies.

RESUMO

OBJECTIVE: A randomized, double-blinded, crossover, placebo controlled trial was conducted to evaluate the efficacy and safety of 0.075% capsaicin lotion for treating painful diabetic neuropathy (PDN). PATIENTS AND METHODS: PDN subjects were randomized to receive 0.075% capsaicin/placebo for 8 weeks, then crossing over to the other treatment after a 4-weeks washout period. Primary endpoint was the change in visual analog scale score of pain severity. Secondary outcomes were score changes in Neuropathic Pain Scale, short-form McGill Pain Questionnaires, and proportions of patients with pain score reductions of 30% and 50%, and adverse events. RESULTS: A total of 42 subjects were enrolled, 27 completed at least an 8-week treatment period. Intention-to-treat analysis showed no significant improvement in pain control with capsaicin lotion compared with placebo for all pain measures and proportion of patients who had 30% or 50% pain relief, respectively. Per protocol analysis were consistent. Capsaicin lotion was well tolerated but local skin reactions were common. CONCLUSION: In patients with PDN, the efficacy of 0.075% capsaicin lotion was similar to placebo but was well tolerated. More work is needed to assess different capsaicin formulations.
