RESUMO

BACKGROUND: Acne vulgaris is a common chronic inflammatory disorder of the pilosebaceous unit, characterized by papules, pustules and/or nodules manifesting primarily on the face and/or upper back that can leave scars, post-inflammatory hyperpigmentation (PIH) and erythema (PIE). OBJECTIVE: To evaluate the anti-inflammatory properties of a protein-free sap extruded from Rhealba® oat plantlets and a Garcinia mangostana extract on Cutibacterium acnes-induced inflammation in vitro and assess the tolerability and efficacy of a dermocosmetic product containing these actives in subjects with mild-to-moderate acne. METHODS: Monocyte-derived dendritic cells (Mo-DCs) from acne patients were stimulated with a planktonic culture of C. acnes and cytokine production was evaluated before and after addition of the test extracts by RT-PCR and ELISA. The clinical study was conducted in subjects with mild-to-moderate acne who applied the product to their face and upper back twice-daily for 2 months. RESULTS: Cutibacterium acnes-induced IL-6, IL-12p40, IL-10 and TNFα synthesis was reduced by the addition of the Garcinia mangostana extract and oat sap in vitro. The clinical study included 54 subjects. The 2-month, twice-daily application of the test product to the whole face and acne-affected areas on the upper back was well tolerated. It led to significant decreases in the number of retentional (-21% for 69% of subjects at D57) and inflammatory (-35% for 79% of subjects at D57) acne lesions, as well as a decrease in Global Acne Evaluation severity scores (2.5 at D1, 2.2 at D29 and 2.1 at D57). The dermatologist also rated the product as effective or very effective in most subjects with PIE (82%; n = 33/40) and PIH (70%; n = 8/11) at D57. CONCLUSION: The actives demonstrated anti-inflammatory effects in vitro, and the dermocosmetic product showed good clinical efficacy and tolerability in subjects with mild-to-moderate acne, supporting the use of this product in acne management.

RESUMO

BACKGROUND: The skin microbiota is known to be imbalanced in acne vulgaris, but the changes occurring during the early stages of acne onset remain poorly described. OBJECTIVES: To characterize the skin microbiome of subclinical stages of acne in adults and adolescents. METHODS: The composition and diversity of the microbiota from non-lesional skin on the forehead of subjects with mild-to-moderate acne were compared to the ones from non-acne subjects. Analyses of skin swab samples were performed using high-throughput sequencing of the V1-V3 regions of the bacterial 16S ribosomal RNA gene, the tuf gene fragment of Staphylococcus species and the internal transcribed spacer (ITS1) region of the fungal rRNA gene to determine the relative abundance, alpha-diversity and beta-diversity of bacteria and fungi. RESULTS: Compared with non-acne subjects, acne subjects had a higher abundance of Cutibacterium (72.4% vs. 57.8%) and lower abundances of Corynebacterium (2.8% vs. 4.8%) and Streptococcus (1.4% vs. 3.2%). Bacterial alpha- and beta-diversity indices also differed significantly between the two groups, reflecting differences in richness, evenness, abundance and phylogenetic distance between bacterial populations. Differences were also observed at the level of Staphylococcus species: S. capitis was predominant in skin samples from non-acne subjects (46.7%), whereas S. epidermidis was the most abundant Staphylococcus species in non-lesional forehead skin areas of acne subjects (44.2%). Conversely, no significant between-group differences were found for fungi, with Malasseziales being the predominant order in both subject groups. CONCLUSION: Dysbiosis was observed very early in subclinical acne stages of the forehead skin, with the overall abundance, richness and evenness of the bacterial population being lower in acne than in non-acne skin samples. Dysbiosis was also found at the level of Staphylococcus species. The development of acne lesions could therefore be prevented by using a skin care product that rebalances facial skin microbiota at very early stages.

RESUMO

BACKGROUND: Rosacea is a chronic inflammatory disease of the facial skin that affects all skin types and occurs mostly in adults. The main clinical sign of rosacea is a characteristic and persistent form of centro-facial erythema that is prone to exacerbation and can impair quality of life (QoL). The current therapeutic approach for rosacea is to combine various treatments, use appropriate skincare products and avoid flare-up triggers. OBJECTIVE: To evaluate the use of a facial skincare product containing protein-free sap extruded from Rhealba® oat plantlets and mandarin extract in subjects with rosacea. METHODS: Three clinical studies were conducted in adult subjects with various rosacea phenotypes (erythematotelangiectatic or papulopustular) and treatment histories to assess the dermatological and ophthalmological tolerance of the study product, as well as its clinical effectiveness, after a twice-daily application on the whole face and neck for up to 4 weeks. RESULTS: Tolerance of the product was rated as good to very good by dermatologists across the three studies, which involved a total of 105 evaluable subjects. Subjects with untreated erythematotelangiectatic rosacea reported fewer functional signs and symptoms of the disease and an improved QoL. The evaluation of skin biometric parameters revealed a reduction in transepidermal water loss, indicating that the study product helped to restore skin barrier integrity after 4 weeks, and a higher skin pH, indicating that the cutaneous microbiote was respected. Most subjects (93%) who had either undergone a superficial dermatological procedure for erythematotelangiectatic rosacea or were taking oral/topical treatments for papulopustular rosacea, rated the study product as very good (8/10) and felt it further relieved their symptoms. CONCLUSION: Overall, the study product was very well tolerated and may be beneficial for subjects with rosacea as an adjunct to superficial dermatological procedures or oral/topical therapies, in line with the current recommendations for rosacea management.

RESUMO

BACKGROUND: Chronic cutaneous pain has a substantial negative impact on quality of life (QoL). Dermo-cosmetics can support therapies for treatment of chronic skin diseases, providing symptomatic relief from chronic cutaneous pain and improved QoL. OBJECTIVES: To assess the global tolerance and efficacy of a dermo-cosmetic spray containing Rhealba® Oat Plantlet and Uncaria tomentosa extracts in reducing cutaneous pain when used as a monotherapy or in association with drug or dermo-cosmetic treatments in patients with an underlying skin pathology. METHODS: Patients aged ≥1 month with a cutaneous pain level ≥3 and an underlying skin pathology were provided with the spray to use up to six times daily for 6-8 weeks. Immediate effect on cutaneous pain and patient satisfaction were assessed after the first application. Global efficacy and tolerance, reduction in symptoms, improvement in QoL, pain reduction and patient overall satisfaction were assessed after 6-8 weeks. RESULTS: Immediately after the first application, significant reductions in cutaneous pain were observed across all age groups (P < 0.0001), with 94% of patients reporting a reduction in pain. After 6-8 weeks, global tolerance was rated 'very good' or 'good' for 97% of patients, and the spray was efficacious in 95% of patients. Patient satisfaction with the efficacy of the spray was 95%. QoL scores improved in 86% and 94% of patients aged ≥12 and <12 years, respectively. Findings were similar across underlying pathology and therapy types (monotherapy or in association with another therapy). CONCLUSIONS: The spray was well-tolerated and efficacious in providing symptom relief in patients with mild-to-moderate cutaneous pain, irrespective of the underlying pathology or therapy type.

RESUMO

BACKGROUND: Inflammation from skin conditions such as psoriasis, eczema-like atopic dermatitis (AD) and hand eczema (HE) and following dermatological procedures (post-acts) can result in intense itching and cutaneous pain. Dermo-cosmetics containing plant extracts have been shown to reduce or alleviate these symptoms. OBJECTIVES: Assessment of the tolerability and efficacy of a spray containing Rhealba\xAE Oat plantlets and Uncaria tomentosa extracts in adults and children with inflammatory skin diseases and after dermatological procedures. METHODS: Data from five open label studies were analysed (Study 1: adults with AD; Study 2: children with AD; Study 3: adults with psoriasis; Study 4: adults with HE; Study 5: adults who had undergone a dermatological procedure: laser, intense pulsed light, glycolic acid peeling, photodynamic therapy or cryotherapy procedure). In all studies, subjects could use the test product up to six times per day for symptom relief. Physical and functional signs of inflammation, treatment-emergent adverse events (TEAEs), soothing effect, changes in quality of life, cutaneous pain and cosmetic acceptability were compared pre- and postapplication. RESULTS: A total of 176 subjects were enrolled across the five studies. Overall, investigators judged the dermatological tolerance of the test product containing Rhealba\xAE Oat plantlets extract and Uncaria tomentosa as good to excellent. All studies showed significant improvements in physical signs, reduction in itching and feeling of pain (P < 0.05). The soothing effect was evident after the first application. TEAEs were mostly mild, transient and occurred within the first few days of treatment. The majority of subjects reported improved QoL across the studies. CONCLUSIONS: The dermo-cosmetic spray containing Rhealba\xAE Oat plantlets extract and U. tomentosa was well tolerated and efficacious in providing relief of symptoms associated with cutaneous pain from inflammatory skin diseases and following dermatological procedures; however, further studies are needed to rule out alternative explanations of symptom reduction such as natural history and response biases.

RESUMO

BACKGROUND: The frequency of dermatological procedures is steadily increasing, accompanying a growing demand from patients. Chemical peels are a method of resurfacing in the treatment of various skin conditions. However, during the early healing process, patients may impose downtime on themselves. The erythema, pain and poor aesthetic appearance of the skin can lead to unwillingness to participate in social or professional activities. OBJECTIVES: The objective of this study was to evaluate the tolerance and efficacy of a repair cream based on Rhealba Oat plantlets extract and active healing compounds after a peeling procedure. METHODS: Men and women, aged 18-65 years, with Fitzpatrick phototype I-IV, who had previously received a medium-depth chemical peel on the face (TCA 30%) entered with their consent a clinical study evaluating the new test product based on Rhealba Oat and active healing compounds. At the beginning of the study, the selected patients received a TCA 30% medium-depth peel. Afterwards, they were treated during 29 days with the repair cream and evaluated for the benefits to downtime and pain. RESULTS: Significant reductions of pain (P < 0.0114) and erythema (P < 0.0001) were observed in the study. The downtime reduction with the tested cream was 92% - from 9 days after the previous peeling procedure to 0.74 days with application of the tested cream - a difference of 8.39 days. CONCLUSION: In consequence, the tested repair cream based on Rhealba Oat plantlets extract and active healing compounds brings clinical benefit to patients who undergo peeling procedures. By reducing pain and downtime, it allows patients to get back to their daily life activities a week earlier than with previous peels.

RESUMO

OBJECTIVE: Correction of iodine deficiency diminishes the incidence of toxic nodular goitre. The aim of this study was to assess the etiology of thyrotoxicosis in two areas with different goitre prevalence in Galicia, fifteen years after the institutional campaign of salt iodination. Results of the present survey are compared with those from a study performed ten years ago. METHODS: Two hundred and two thyrotoxic patients attended in La Coruña (coastal zone) and Lugo (inland zone) from January 2000 to May 2002 were included. Clinical and exploratory data were recorded. Thyroid hormones, thyroid-directed antibodies and thyroid stimulating immunoglobulin (TSI) were measured. A thyroid 99m technetium or 123 iodine scintigram was performed. RESULTS: In the whole group 58.6% of the cases were diagnosed of nodular goitre, 30.3% of Graves disease, 7.1% of iodine induced thyrotoxicosis and 3.5% of subacute thyroiditis. In coastal zone these percentages were 52.2, 37.0, 5.4 and 4.3%, respectively. In the inland area, 64.2% nodular goitre, 24.5% Graves disease, 8.5% iodine induced thyrotoxicosis and 2.8% subacute thyroiditis. The most frequent diagnosis in both the whole group and in each area was toxic multinodular goitre. CONCLUSIONS: In some areas of Spain, toxic nodular goitre continues to be the most frequent cause of thyrotoxicosis. It is necessary to insist on implementation and monitoring of iodine supplementation programs.

RESUMO

We report the ultrasound, CT, and MR findings in a patient with Riedel thyroiditis. The hypointensity of the lesion observed on T1- and T2-weighted sequences, especially when associated with infiltration of adjacent structures of the neck, can be suggestive of Riedel thyroiditis.
