RESUMEN

BACKGROUND: Although there is a standard guideline for the treatment of acne, it is still a common skin disease, and suboptimal medication adherence is a major reason for treatment failure. Herbal extracts are an interesting alternative medicine because they consist of a variety of active ingredients. Moreover, herbal extracts may have improved therapeutic efficacy because of the combination of various herbs. OBJECTIVES: To evaluate the effectiveness of herbal extracts for the treatment of mild to moderate acne vulgaris. METHODS: A total of 77 patients were randomized to receive either an herbal extract or 2.5% benzoyl peroxide, which were applied for a period of 12 weeks. Acne lesion counts, adherence, porphyrin counts, the Dermatology Life Quality Index, satisfaction and side effects were assessed. RESULT: At the 12-week point, the acne lesion counts decreased, with statistically significant differences from the baseline values in both groups and for all types of acne (P-value < 0.001). The adherence rate was significantly higher in the patients using the herbal extract than in the patients using 2.5% benzoyl peroxide (P-value = 0.002). There was no statistically significant difference in terms of porphyrin counts, spot scores, the Dermatology Life Quality Index or satisfaction with efficacy between the groups; however, satisfaction with drug administration was significantly higher in the patients using the herbal extract (P-value = 0.001). CONCLUSION: Herbal extracts could be beneficial for anti-acne pharmaceutical preparations and may be used as an alternative medicine for patients with mild to moderate acne vulgaris who do not adhere to benzoyl peroxide treatment.

RESUMEN

Acne and rosacea are common inflammatory processes historically classified in the same disease category, but evolving understanding of their disparate pathophysiology and exacerbating factors have generated an enormous armamentarium of therapeutic possibilities. Patients seek over-the-counter therapies first when managing cutaneous disease; therefore, this review defines ingredients considered to be effective over-the-counter acne and rosacea products, their mechanisms, and safe formulations, including botanical components, oral supplements, and other anecdotal options in this vast skin care domain.

RESUMEN

A supplement article recently published in the Journal of the European Academy of Dermatology and Venereology by Dréno et al., members of the Global Alliance to Improve Outcomes in Acne group, summarized the data for the emerging concept that inflammation in general and the innate immune system specifically play a central role in the pathogenesis of acne. This review, entitled "Understanding innate immunity and inflammation in acne: implications for management", also discusses the impact of different treatment options on the innate immune response and inflammation. The aim of the present summary is to provide a synopsis of the key points made in the paper, from the members of the Global Alliance, as relevant to the main article within this supplement: "Recent advances in the use of adapalene 0.1%/benzoyl peroxide 2.5% to treat acne patients with moderate to severe acne".

RESUMEN

BACKGROUND: Over-the-counter acne treatments have assumed more importance for the dermatologist as access and affordability of prescription acne medications has decreased. AIM: This research evaluated the efficacy of a three step acne treatment regimen containing stabilized botanical anti-inflammatory ingredients as compared to a currently marketed acne regimen. METHOD: 80 female/male subjects 12+ years with mild to moderate acne (at least 10 inflammatory and 10 non-inflammatory lesions) were enrolled for 12 weeks and randomized to use the study botanical anti-inflammatory acne regimen or the traditional benzoyl peroxide comparator. Evaluations included investigator global assessment, investigator tolerability assessment, acne lesion characteristics (erythema, lesion height, diameter of inflammation, and amount of pus), subject product assessment, and digital photos at baseline, 2, 4, and 12 weeks. RESULTS: The botanical regimen outperformed the comparator in terms of target lesion erythema, height, inflammation, and pus at weeks 2 and 4, perhaps due to anti-inflammatory ingredients, however parity was reached between the two products by week 12. No difference in lesion counts between the two groups was noted at week 2, however by week 4, there was a lower lesion count with the study regimen in terms of closed comedones (P<0.001) and inflammatory (P=0.016) lesions than the comparator. This statistically significant difference continued into week 12 with a reduction in closed comedones (P=0.006) for the study regimen. CONCLUSION: Modern OTC cosmetic formulation ingredients including emollients, anti-inflammatory/antioxidants, and sensitive skin modulators provided an improved skin appearance, less lesional erythema, and a better overall appearance in subjects with acne treated for 12 weeks.

RESUMEN

Combination therapy using medications with complementary mechanisms of action is the standard of care in treating acne. We report results of a clinical trial evaluating the use of a fixed-dose tretinoin 0.025%/clindamycin phosphate 1.2% (T/CP) gel in combination with a benzoyl peroxide 6% foaming cloth compared with T/CP alone for facial acne. At week 12, the combination therapy group showed a trend toward greater efficacy compared with T/CP alone. There was a high success rate observed in the study, which may be attributable to the large percentage of adult female acne patients enrolled. Cutaneous adverse events were not statistically different in using combination therapy compared with T/CP alone.

RESUMEN

The goals of this study were to determine if adding annatto color to milk or applying a bleaching process to whey or microfiltration (MF) permeate influenced ultrafiltration (UF) flux, diafiltration (DF) flux, or membrane fouling during production of 80% whey protein concentrate (WPC80) or 80% serum protein concentrate (SPC80). Separated Cheddar cheese whey (18 vats using 900 kg of whole milk each) and MF permeate of skim milk (18 processing runs using 800 kg of skim milk each) were produced to make WPC80 and SPC80, respectively. The 6 treatments, replicated 3 times each, that constituted the 18 processing runs within either whey or MF permeate UF were as follows: (1) no annatto; (2) no annatto+benzoyl peroxide (BPO); (3) no annatto+hydrogen peroxide (H2O2); (4) annatto; (5) annatto+BPO; and (6) annatto+H2O2. Approximately 700 kg of whey or 530 kg of MF permeate from each treatment were heated to 50°C and processed in 2 stages (UF and DF) with the UF system in batch recirculation mode using a polyethersulfone spiral-wound UF membrane with a molecular weight cutoff of 10,000 Da. Addition of annatto color had no effect on UF or DF flux. The processes of bleaching whey or MF permeate with or without added color improved flux during processing. Bleaching with H2O2 usually produced higher flux than bleaching with BPO. Bleaching with BPO increased WPC80 flux to a greater extent than it did SPC80 flux. Though no differences in mean flux were observed for a common bleaching treatment between the WPC80 and SPC80 production processes during the UF stage, mean flux during WPC80 DF was higher than mean flux during SPC80 DF for each bleaching treatment. Water flux values before and after processing were used to calculate a fouling coefficient that demonstrated differences in fouling which were consistent with flux differences among treatments. In both processes, bleaching with H2O2 led to the largest reduction in fouling. No effect of annatto on fouling was observed. The reasons for flux enhancement associated with bleaching treatments are unclear.

RESUMEN

OBJECTIVE: To evaluate the clinical effectiveness and safety of Chinese medical facial mask comprehensive therapy in treating acne vulgaris. METHODS: Totally 233 acne vulgaris patients (FAS set) in I -III degree were randomly assigned to the facial mask group (113 cases) and the Western medicine group (120 cases). They were respectively treated with external application of Chinese medical facial mask (twice a week) and 5% benzoyl peroxide gel (Benzine, once in the evening). The treatment lasted for four successive weeks. The integrals of lesions and the improvement of Chinese medicine syndrome integrals were observed 1 week, 2 weeks and 4 weeks after treatment respectively. The occurrence of adverse reactions was recorded. The subjects' evaluation on using the Chinese medical facial mask comprehensive therapy was also recorded. RESULTS: Totally 228 of the 233 patients completed the therapeutic course (7 cases of overtime, 221 cases of PPS set, 105 cases in the facial mask group and 116 cases in the Western medicine group). After 4 weeks of treatment, the lesions and the total effective rate of CM symptoms were obviously higher in the facial mask group than in the control group (46.9% vs 30.0%, 70.8% vs 55.8%, P < 0.05). The statistical results of FAS set and PPS set showed no difference. After 4 weeks of treatment, the integrals of PPS lesions and the CM syndrome integrals in the facial mask group were lower than in the Western medicine group, showing statistical difference (P < or = 0.05). After 2 weeks and 4 weeks of treatment, the integrals of lesions and the CM syndrome integrals of FAS set and PPS set were all higher in the facial mask group than in the control group (P < 0.05). The occurrence of adverse reactions was 1.8% (2/113) in the facial mask group and 2.5% (3/120) in the control group without statistical difference (P > 0.05). CONCLUSIONS: Chinese medical facial mask comprehensive therapy is safe and effective in treating acne vulgaris of I - III degree. The occurrence of adverse reactions is very low. It is easy to operate and spread.

RESUMEN

Progressive macular hypomelanosis (PMH) is an acquired disorder of skin pigmentation, which is mostly under-diagnosed. It is characterized by nummular hypopigmented lesions appearing on the trunk in young persons. Several treatment options are available, although topical clindamycin and benzoyl peroxide have been used traditionally. However, good results have recently been achieved using narrow-band ultraviolet B (NBUVB) phototherapy. We present the case of a 13-year-old girl with hypopigmented lesions on the trunk and limbs that had progressed over 1 year and that were diagnosed as PMH. The patient was initially treated with topical clindamycin and benzoyl peroxide. However, little improvement was seen and treatment was then started with NBUVB phototherapy. After 25 sessions, with a total cumulative dose of 18 J/cm(2) , the patient showed almost total repigmentation of the lesions. The treatment of PMH is often difficult, and very little is currently known about the treatment response in this disorder, as most reports have very small series of patients with a short disease progression time. NBUVB phototherapy has been shown to be effective, as seen in our patient, although in many cases, there is recurrence after the cessation of treatment.

RESUMEN

Benzoyl peroxide (BPO) is a commonly used and highly effective topical treatment for acne that is available in concentrations from 2.5-10%. The compound is not associated with bacterial resistance, and published acne treatment guidelines recommend BPO in conjunction with the long-term use of both topical and systemic antibiotics. A number of combination products containing antibiotics, BPO and/or retinoids are available and useful for tailoring treatment to the needs of each patient over the course of what is often a chronic condition. Fixed combinations of BPO and antibiotics or retinoids address multiple pathogenetic factors by using agents with complementary, but different modes of action. These agents are convenient to use and may improve adherence to therapy by simplifying the regimen for the patient. However, BPO is associated with dose-dependent irritation and dryness. Therefore, formulations containing lower concentrations of BPO (2.5%) minimize irritation, which may improve tolerability and maximize treatment outcomes.

RESUMEN

This article reviews various studies supporting the use of a fixed-combination monotherapy hydrating gel containing clindamycin 1% and benzoyl peroxide 5% (C/BPO), which is the only available formulation with a hydrating gel vehicle containing a humectant and an occlusive. The C/BPO hydrating gel provides a flexible and complementary efficacy and/or tolerability profile when used alone or with topical retinoids, which results in rapid response in inflammatory and noninflammatory acne. It also mitigates the irritation associated with disease flare or topical retinoid use, and reduces the postinflammatory hyperpigmentation (PIH) seen in women and in patients with skin of color with acne. These benefits are important because they have the potential to improve patient adherence to therapy and clinical outcomes.

RESUMEN

FUNDAMENTOS: Muitos pacientes relatam melhora da acne com a exposição à luz solar, e vários estudos demonstram que a luz azul é efetiva no tratamento da acne. OBJETIVOS: Verificar a segurança e a eficácia da luz azul (espectro eletromagnético de 407 a 420 nm) no tratamento da acne inflamatória graus II e III, comparada à terapêutica tópica com peróxido de benzoíla a 5 por cento. MÉTODOS: O estudo avaliou 60 pacientes em cinco visitas: uma de seleção, uma com 7, 14 e 28 dias de tratamento e uma última de seguimento, 14 dias após o término do tratamento. Trinta foram randomizados para luz azul (oito sessões, duas vezes por semana), e outros 30, para peróxido de benzoíla a 5 por cento, duas vezes ao dia, diariamente. A avaliação foi por meio da contagem das lesões e fotografias. RESULTADOS: A redução no número médio de lesões foi semelhante com os dois tratamentos, independente do tipo de lesão (p 0,05), porém o tratamento com a luz azul apresentou menos efeitos colaterais. CONCLUSÕES: A luz azul foi um tratamento tão eficaz quanto o peróxido de benzoíla a 5 por cento para o tratamento da acne graus II e III, mas com menos efeitos adversos.


BACKGROUND: Many acne patients improve after exposure to sunlight and there are many reports about the efficacy of blue light phototherapy on acne lesions. OBJECTIVES - The purpose of this study was to evaluate efficacy and safety of blue light treatment versus topical benzoyl peroxide 5 percent formulation in patients with acne grades II and III. METHODS - Sixty volunteers with facial acne were included and evaluated in 5 visits: the first one for screening, another 3 held on days 7, 14 and 28 of treatment, and the last one after 14 days of the end of treatment. Thirty of them were irradiated with Blue Light (8 times, twice a week) and the other thirty were treated with topical Benzoyl Peroxide 5 percent formulation, auto-applied twice a day, every day. We assessed the severity of acne by counting the lesions and analyzing the photographs. RESULTS - The improvement achieved by the blue light was the same as the one with benzoyl peroxide, regardless of the type of lesion (p 0.05). Otherwise, the side effects were less frequent in the group treated with blue light. CONCLUSIONS - Blue light irradiation was as effective as Benzoyl Peroxide in acne treatment grades II and III but there were fewer side effects.

RESUMEN

International guidelines recommend the combination of retinoids (e.g. adapalene, tazarotene) and benzoyl peroxide for treating acne because of their complementary mechanisms of action. A new fixed-dose combination gel of adapalene 0.1% and benzoyl peroxide (BPO) 2.5% (adapalene/BPO*) is an effective acne treatment and offers the advantage of a once daily application. This paper reports the results of a cumulative irritancy study in healthy volunteers comparing adapalene/BPO to adapalene 0.1% and BPO 2.5% applied separately, BPO 10% gel, tazarotene 0.1% gel and the gel vehicle as a control.There was no significant difference between the mean cumulative irritation index (MCII) for adapalene/BPO and any test product except tazarotene 0.1% gel, which had a significantly greater MCII than all other test products (p < 0.05). This study showed that adapalene/BPO as a fixed-dose combination is as well tolerated as BPO 2.5% gel alone or adapalene 0.1% gel alone in terms of cumulative irritancy.*Epiduo, Galderma S.A.

RESUMEN

The management of acne is a gratifying experience. Available treatments are effective, relatively nontoxic and generally safe. However, there is no quick fix. Antibiotics, hormone therapies and topical therapies are maintenance treatments. Isotretinoin can induce remission, as can some of the newer physical modalities of lights, lasers and radiofrequency devices. Effective management of acne often requires using a combination of treatments that act on different parts of the pathogenic process of acne development.

RESUMEN

The current study unveils the effect of O. echioides extract on two-stage skin carcinogenesis and on tumor promoter induced markers and oxidative stress in Swiss mice. Treatment of dorsal shaven cutaneous portions of the mice with single topical application of benzoyl peroxide (BPO) followed by exposure to ultraviolet B (UVB) radiation induced significant oxidative stress and elevated the marker parameters of tumor promotion. Similar effects were observed with 12-O-tetradecanoyl phorbol-13-acetate (TPA) treatment. Pretreatment of O. echioides extract (5 mg & 10 mg/Kg b.wt) in both the studies with BPO+UVB and TPA restored the levels of reduced glutathione (GSH) and cellular protective enzymes (p < 0.05). Concomitantly, malondialdehyde (MDA) formation and hydrogen peroxide (H2O2) content were also reduced significantly (p < 0.05) at both the doses. The promotion parameters tested (ornithine decarboxylase activity and DNA synthesis) were also significantly suppressed (p < 0.05). Thereafter, we proceeded with studies on mouse skin carcinogenesis. After ten days of 7,12-dimethylbenz(a)anthracene (DMBA) treatment, twice-weekly applications of croton oil for 20 weeks resulted in 100% incidence of tumors in the animals. However, O. echioides showed reduction in the number of tumors/ mouse and percentage of tumor bearing mice at the end of the study. The study was further histologically confirmed. The protective activity of the plant might be due to the two major constituents (alkannins and shikonins) present in the plant. O. echioides is thus, proposed to be helpful in prevention of experimental skin carcinogenesis.

RESUMEN

Tea-tree oil (an essential oil of the Australian native tree Melaleuca alternifolia) has long been regarded as a useful topical antiseptic agent in Australia and has been shown to have a variety of antimicrobial activities; however, only anecdotal evidence exists for its efficacy in the treatment of various skin conditions. We have performed a single-blind, randomised clinical trial on 124 patients to evaluate the efficacy and skin tolerance of 5% tea-tree oil gel in the treatment of mild to moderate acne when compared with 5% benzoyl peroxide lotion. The results of this study showed that both 5% tea-tree oil and 5% benzoyl peroxide had a significant effect in ameliorating the patients' acne by reducing the number of inflamed and non-inflamed lesions (open and closed comedones), although the onset of action in the case of tea-tree oil was slower. Encouragingly, fewer side effects were experienced by patients treated with tea-tree oil.

RESUMEN

In this excellent article, Dr. McCarthy presents some of the most current concepts in the treatment of lower extremity ulcerations. This common clinical finding is frequently frustrating and difficult to treat effectively. It also requires a high degree of suspicion as to the primary underlying cause and many hours of careful treatment and follow-up to prevent serious secondary complications, such as infection and gangrene. The emphasis on therapeutic approaches lends much useful information in our fight with this condition and its sequelae.
