Sinecatechins and imiquimod as proactive sequential therapy of external genital and perianal warts in adults.

This review about the proactive sequential therapy (PST) of external genital and perianal warts (EGW) is based on the most current available clinical literature and on the broad clinical experience of a group of international experts, physicians who are well versed in the treatment of human papillomavirus-associated diseases. It provides a practical guide for the treatment of EGW, including epidemiology, etiology, clinical appearance, and diagnostic procedures for these viral infections. Furthermore, the treatment goals and current treatment options, elucidating provider- and patient-applied therapies, and the parameters driving treatment decisions are summarized. Specifically, the mode of action of the topical treatments sinecatechins and imiquimod, as well as the PST for EGW to achieve rapid and sustained clearance is discussed. The group of experts has developed a treatment algorithm giving healthcare providers a practical tool for the treatment of EGW which is very valuable in the presence of many different treatment options.

ß-Glucan-based cream (containing pleuran isolated from pleurotus ostreatus) in supportive treatment of mild-to-moderate atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases with serious impact on quality of life. ß-Glucans are natural substances with potent immunomodulatory and anti-inflammatory activity. METHODS: In a multicentre open split-body study, we studied the effect of Imunoglukan P4H® cream in a group of 105 patients with AD (39 males, 37%). Evaluation of subjective (visual analogue scale, VAS) and objective (EASI score, eczema area and severity index) characteristics of AD was carried out. RESULTS: In total, 80 patients (76.2%) completed the study. Topical ß-glucan application resulted in the significant improvement of both objective and subjective symptoms of AD. On the application side, significant decline in the number of days with AD exacerbation and its severity was observed. Moreover, the subjects experienced decline of pruritus on the ß-glucan half of the body (VAS score: 1.68 vs. 1.95, p < 0.001). During the study, the continual and significant decline of EASI scores on the site of ß-glucan application was observed (V4: 1.57 vs. 1.85, p < 0.001). The preparation was in general well tolerated. CONCLUSIONS: This is the first study evaluating and confirming the potential use of ß-glucan-based cream as a supportive complementary therapy of atopic dermatitis.

Treatments of vitiligo: what's new at the horizon.

Vitiligo is a manageable disease. However, current vitiligo treatments can be considered suboptimal as they do not guarantee high efficacy and cannot be standardized for most patients. Recently, combination therapies have been introduced in order to obtain better results and reduce risks in the management of the disease. Novel efficacious products are hereunder discussed to improve the therapeutic options for vitiligo patients.

Vitiligo road map.

Vitiligo is a depigmenting disorder stemming from melanocyte loss or dysfunction. It has a complex, multifaceted etiology. We constructed a "vitiligo road map," consisting of basic science, clinical, and treatment components, in order to better portray our current understanding of vitiligo pathogenesis and reflect upon novel biomarkers and therapeutic targets for future research. The melanocyte map elaborates on the molecular processes and intracellular signaling pathways initiated by various external autocrine/paracrine factors in representing normal melanocyte homeostatic functions modulating its viability, proliferation, differentiation, dendricity, migration, and melanogenic processes. This vitiligo map identifies known inducers/triggers of vitiligo onset and progression that cultivate a microenvironment for melanocyte disappearance, real or functional. This map describes the molecular mechanisms of currently utilized clinical and experimental treatments of vitiligo that facilitate repigmentation.

Clinical efficacy of a novel topical formulation for vitiligo: compared evaluation of different treatment modalities in 149 patients.

Current vitiligo treatments are not always satisfactory for both patients and dermatologists. Recently, combination therapies have been introduced in order to obtain better results and reduce risks in the management of the disease. Novel efficacious products are needed to improve the therapeutic possibilities of dermatologists in the respect of safety for the patients. The objective of the present study was to evaluate the effects of a novel topical in a gel formulation containing phenylalanine, cucumis melo extract, and acetyl cysteine in vitiligo. The present study used an open observational study to evaluate the efficacy and safety of the investigated product, given alone or in combination with 311-nm narrow band microphototherapy. Results were compared with those obtained treating a matched patient population with microphototherapy alone and with clobetasol propionate 0.05% ointment alone. One hundred forty-nine patients suffering from symmetrical vitiligo affecting less than 10% of the skin surface were evaluated. Patients affected by acral vitiligo only were excluded from the analysis. Treatment duration was scheduled for 12 weeks. Excellent repigmentation (>75%) was achieved by 38-73% of patients, depending on the treatment regimen. Mild to moderate side effects were observed only in patients treated with clobetasol 0.05% ointment. The tested gel formulation showed a good efficacy in improving vitiligo repigmentation. No side effects were observed.

Management of lymphedema.

The basic principle of the management of lymphedema is so called complex decongestive physical therapy. This therapy is divided into two phases: (i) edema reduction phase--an initial intensive treatment phase aiming for limb volume reduction; and (ii) maintenance phase--following long-term phase to sustain a manageable limb volume. The first phase consists of a number of physical therapeutic approaches which are: manual lymph drainage, pneumatic pump drainage, low-stretch bandaging, exercises, and skin care. Long-term maintenance phase consists of self-lymph drainage, low-stretch bandaging, or compressive garments, and sometimes when indicated pneumatic pump drainage, exercises, and skin care.

Targeted and combination treatments for vitiligo. Comparative evaluation of different current modalities in 458 subjects.

The current treatment of vitiligo is not satisfactory according to the opinions of both the patient population and the dermatologists. Recently, combination therapies have been introduced, which are both systemic and targeted (microphototherapy). To evaluate the effects of topical treatments given alone or in combination with 311-nm narrow-band microphototherapy. We evaluated the efficacy and safety of: (1) 311-nm narrow-band microphototherapy;(2) tacrolimus 0.1% ointment twice a day; (3) pimecrolimus 1% cream twice a day; (4) betamethasone dipropionate 0.05% cream twice a day; (5) calcipotriol ointment 50 microg/g twice a day; and (6) 10%l-phenylalanine cream twice a day, for the treatment of exclusively vitiligo patches. A 311-nm narrow-band microphototherapy (Bioskin) was given alone or in combination with the above-mentioned popular local treatments. Four hundred and seventy patients suffering from vitiligo that affected less than 10% of the skin surface were evaluated. The patients were divided into 11 groups according to the selected treatment modalities. Four hundred and fifty-eight patients completed the study period of 6 months. Excellent repigmentation (> 75%) was achieved by 72% of the patients in group 1, 76.5% in group 2, 76.1% in group 3, 90.2% in group 4, 75.6% in group 5, 74.8% in group 6, 61% in group 7, 54.6% in group 8, 71.2% in group 9, 59.1% in group 10, and 29.3% in group 11. Marked repigmentation (50-75%) was evident in 19.8% of the patients in group 1, 18.2% in group 2, 20.1% in group 3, 6.7% in group 4, 14.1% in group 5, 11.3% in group 6, 16.1% in group 7, 18.4% in group 8, 25% in group 9, 10.6% in group 10, and 8.1% in group 11. Moderate results (25-50% repigmentation) were seen in 4.6% of the patients in group 1, 3.3% in group 2, 2.7% in group 3, 2.2% in group 4, 7.4% in group 5, 10.1% in group 6, 18.4% in group 7, 21.7% in group 8, 2.1% in group 9, 27.1% in group 10, and 55% in group 11. Finally, minimal (< 25%) or no response was achieved in 3.6% of the patients in group 1, 2% in group 2, 1.1% in group 3, 0.9% in group 4, 2.9% in group 5, 3.8% in group 6, 4.5% in group 7, 5.3% in group 8, 1.75% in group 9, 3.2% in group 10, and 7.6% in group 11. Side effects were skin atrophy (76% in group 4 and 81% in group 9), stinging and burning (groups 2, 3, 7, and 8). Targeted combination therapies in vitiligo are remarkably more effective than single treatments. When single treatments are considered alone, 311-nm narrow-band UVB microfocused phototherapy and 0.05% betamethasone dipropionate cream are the most effective treatments in our study. When combined therapies are chosen, 0.05% betamethasone dipropionate cream plus 311-nm narrow-band UVB microfocused phototherapy apparently give the highest repigmentation rate. In the short term, the only side-effects registered have been cutaneous atrophy with corticosteroid cream, and stinging and burning with 0.1% tacrolimus ointment and, less frequently, with 1% pimecrolimus cream.

A rational approach to the treatment of vitiligo and other hypomelanoses.

A rational approach to hypopigmented disorders needs a clear and widely accepted classification and meta-analysis of the literature to position the medical, physical, surgical, and combined treatments available in terms of safety and effectiveness profiles. Best available scientific evidence must be rationally adapted to the patient's expectations and to the clinical presentation of the hypopigmentary disease, to reach the most valid final results.

Incidental granular parakeratosis associated with molluscum contagiosum.

A patient presented with a 4-month history of slowly progressive pruritic papules on her trunk and extremities. Biopsies from 2 of these lesions revealed molluscum contagiosum. One of the biopsies also showed several small foci of granular parakeratosis. Based on the clinical features and course of this patient, the granular parakeratosis seems to be an incidental finding.

Evaluation of dietary intake of vitamin E in the treatment of atopic dermatitis: a study of the clinical course and evaluation of the immunoglobulin E serum levels.

BACKGROUND: Vitamin E (VE) is a potent antioxidant that can improve the immune macrophage-mediated response, decrease the production and/or release of prostaglandins in humans, and decrease the serum levels of immunoglobulin E (IgE) in atopic subjects. AIM: To compare the effects of placebo (PL) and VE intake (400 IU/day) on subjective symptoms and serum IgE levels in 96 subjects with atopic dermatitis. MATERIALS AND METHODS: A single-blind clinical analysis was performed on 96 subjects randomly divided into two groups. Fifty subjects were given orally 400 IU (268 mg) of VE of natural origin, once a day for 8 months, and 46 took PL for the same period. Complete blood count, serum IgE levels, radioallergosorbent test (RAST) score, antinuclear antibodies (ANA), and biochemical analysis were obtained at the time of enrollment and every 15 days during the 8 months of the study. To evaluate VE therapy, a questionnaire was sent to each subject for completion at the end of the study. RESULTS: The results were as follows: (A) four subjects treated with VE worsened, compared to 36 in the PL group; (B) six subjects in the VE group and five in the PL group showed no change; (C) slight improvement was observed in 10 subjects in the VE group and four in the PL group; (D) 23 of the 50 subjects treated with VE showed great improvement, compared to only one in the PL group; and (E) there was almost complete remission of atopic dermatitis in seven of the 50 subjects in the VE group, but none in the PL group. Females showed less progression of atopic dermatitis than males in both groups and a higher percentage of almost complete remission (five females and two males). The range of serum IgE levels varied markedly from 1005 to 490 IU/mL in the VE group and from 1239 to 812 IU/mL in the PL group over 8 months. Subjects with great improvement and near remission of atopic dermatitis in the VE group demonstrated a decrease of 62% in serum IgE levels based on initial conditions, while, in subjects taking PL, the difference was approximately 34.4%. No complications were observed in either group. A remarkable improvement in facial erythema, lichenification, and the presence of apparently normal skin was reported. Eczematous lesions healed mostly as a result of decreased pruritus. CONCLUSIONS: The correlation between VE intake, IgE levels, and the clinical manifestations of atopy indicates that VE could be an excellent therapeutic tool for atopic dermatitis.
