RESUMEN

BACKGROUND: The protection for different skin types with impaired skin barrier in the market is insufficient. AIM: To evaluate the efficacy and safety of a panthenol-enriched mask (La Roche-Posay Mask Pro) in addressing various skin barrier impairment subgroups, including dry sensitive, oily sensitive, and oily acne skin. METHODS: A total of 177 participants were enrolled in the study and divided into three subgroups based on their skin type. Participants used the mask following the specified protocol, with measurements taken for skin hydration, transepidermal water loss (TEWL), sebum content, and skin redness-factors that are directly influenced by skin barrier function. Assessments were conducted at baseline and after 1 day (tested 15 min post-application), 7 days, and 14 days of application using Sebumeter, Tewameter, Corneometer, Mexameter, and VISIA. RESULTS: Results showed significant improvements in skin parameters across all subgroups. In the dry sensitive skin subgroup, the mask increased skin hydration, sebum content, and reduced redness. For the oily sensitive skin subgroup, the mask regulated sebum production and improved skin hydration. In the oily acne skin subgroup, the mask reduced sebum content, redness, TEWL, and post-inflammatory erythema and hyperpigmentation. Tolerance was excellent for all skin types, with no adverse reactions observed. CONCLUSIONS: This study highlights the efficacy and safety of the panthenol-enriched LRP Mask Pro for individuals with distinct skin barrier impairment subgroups. The mask's versatile formulation and proven efficacy make it a valuable skincare product for addressing various skin concerns and achieving healthier, more balanced skin.

RESUMEN

Calcium pantothenate (CAS no. 137-08-6) is the calcium salt of pantothenic acid (vitamin B5). It is used in cosmetics due to its anti-static and hair conditioning properties. A 53-year-old female nurse's aide presented with intermittent facial eruptions (Figure S1). Patch tests were positive to calcium pantothenate, an ingredient of two of her products (a cleansing milk and a facial tonic). To our knowledge, no previous cases of sensitization from calcium pantothenate have been reported except for one case of systemic dermatitis from a nutritional supplement in a dexpanthenol-sensitized patient.

RESUMEN

BACKGROUND: Panthenol (synonym: dexpanthenol), the alcohol analogue of panthothenic acid, is frequently included in moisturizers, wound-healing agents, and other cosmetics, and has been shown to be responsible for allergic contact dermatitis (ACD). OBJECTIVES: To evaluate the frequency of ACD caused by dexpanthenol, and to characterize reactive patients. METHODS: We retrospectively reviewed the files of patients patch tested between 2009 and 2017 in the Department of Dermatology of the Coimbra's University Hospital and describe patients who reacted to dexpanthenol 5% pet., tested initially in a cosmetic/vehicle series and in the last 3 years in consecutive patients. RESULTS: Among 2171 patients, 26 (1.2%) had positive patch test reactions to dexpanthenol, mostly patients tested for chronic eczema (88.5%, n = 23), either widespread (5), or localized to the hands (5), face (4), or legs (7). Relevance could be traced in 20 patients (76.9%), related to the use of Bepanthene cream (15), moisturizers (3), topical medications (1), and a shampoo (1). Twenty-five of 26 patients (96.2%) reacted to several other allergens, mostly ingredients of cosmetic or pharmaceutical products. CONCLUSIONS: Although ACD caused by dexpanthenol is considered to be rare, it may be frequently overlooked. As we found a relatively high frequency of relevant cases, in agreement with a previous study, the inclusion of dexpanthenol in patch test series, at least in cosmetic and topical drug series, is encouraged.

RESUMEN

Coronary artery calcification (CAC) is a widespread condition in chronic kidney disease (CKD). Diet may play an important role in CAC, but this role is not clear. This study evaluated the association between macro-and micronutrient intakes and CAC in non-dialysis CKD patients. We analyzed the baseline data from 454 participants of the PROGREDIR study. Dietary intake was evaluated by a food frequency questionnaire. CAC was measured by computed tomography. After exclusion of participants with a coronary stent, 373 people remained for the analyses. The highest tertile of CAC was directly associated with the intake of phosphorus, calcium and magnesium. There was a higher intake of pantothenic acid and potassium in the second tertile. After adjustments for confounding variables, the intake of pantothenic acid, phosphorus, calcium and potassium remained associated with CAC in the generalized linear mixed models. In order to handle the collinearity between these nutrients, we used the LASSO (least absolute shrinkage and selection operator) regression to evaluate the nutrients associated with CAC variability. In this approach, the nutrients that most explained the variance of CAC were phosphorus, calcium and potassium. Prospective studies are needed to confirm these findings and assess the role of interventions regarding these micronutrients on CAC prevention and progression.

RESUMEN

BACKGROUND: The aim of this paper was to evaluate efficacy and tolerability of a topical gel (ACNAID TM gel medical device) containing 3% hydrogen peroxide (HPO), 1.5% salicylic acid (SA) and 4% D-panthenol (D-p) in the treatment of mild-moderate acne, comparing it with a previous formulation (ACNAID TM gel Cosmetic) containing 4% HPO, 0.5% SA, 4% D-p. METHODS: Twenty patients of both sex with mild-moderate acne have been selected. The topical gel was applied twice a day for 60 days. Evaluations included: Global Acne Grading System (GAGS); lesions count; photographic assessment; a questionnaire to assess the tolerability. The results have been compared with those obtained in a previous study conducted with the formulation containing 4% HPO, 0.5% SA, 4% D-p. RESULTS: The GAGS score showed a reduction of 43% from T0 to T1 and of 61% from T0 to T2. Count of lesions: comedones reduction of 62% from T0 to T1 and of 95% from T0 to T2; papules reduction of 49% from T0 to T1 and of 68% from T0 to T2; pustules reduction of 75% from T0 to T1 and of 100% from T0 to T2. Digital images showed a significant reduction of acne lesions. At T2 the tolerability of the topical product was excellent according to 83% of patients and good according to 17% of patients. CONCLUSIONS: The topical gel has demonstrated to be effective and safe for treatment of mild to moderate acne. No patients reported side effects. These results are superior to those obtained in the previous study.

RESUMEN

AIM: Despite the availability of a number of pharmacological options, relief of allergic rhinitis (AR) symptoms, especially nasal obstruction, is often limited and local and systemic adverse reactions are not infrequent. The main aim of the present pilot study was to provide subjective and objective evidence of the clinical efficacy in reducing symptoms and safety of a medical device-Grip stop DMG (lactoferrin, carboximetil ß-glucan, D-panthenol, dipotassiumglycyrrhizinate) in children affected by allergic rhinitis. METHODS: A prospective study with a pre- and post-design has been performed consecutively enrolling 50 pediatric both genders patients affected by persistent AR. Patients received 2 puffs into each nostril twice a day over the course of 4 weeks. The severity of AR symptoms was assessed subjectively as measured by a 0 to 5 Visual Analog Scale, and objectively through active anterior rhinomanometry (AAR) and by means of the evaluation of mucociliary transport time (MCTt). Differences in symptoms scores measured before and after the treatment were compared using Paired-Sample Wilcoxon Signed Rank Test. Proportion of participants with adverse effects attributed to the treatment was computed. The relationship between the subjective score and the AAR and MCT measurements was also assessed. RESULTS: All considered symptoms, including nasal congestion, significantly improved after treatment (P<0.001), while only 1 patient suffered from moderate adverse effects. CONCLUSION: Results confirm efficacy and safety of this device used in the pediatric population. As previously reported in the scientific literature, also in our study, patient's perception of nasal symptoms corresponded with objective testing.

RESUMEN

Pustular irritant contact dermatitis is rare and unusual clinic form of contact dermatitis. Dexpanthenol is the stable alcoholic analogue of pantothenic acid. It is widely used in cosmetics and topical medical products for several purposes. We present the case of 8-year-old girl with pustules over erythematous and eczematous areas on the face and neck. To the best of our knowledge, this is the first case reported that is diagnosed as pustular irritant contact dermatitis caused by dexpanthenol.

RESUMEN

A randomized study on the efficacy and safety of the hopantenic acid preparation (pantocalcin) and its effect on cognitive functions in children with cerebral palsy (CCP) has been carried out. The positive effect of pantocalcin on the visual memory and attention concentration, activity and fatigability has been shown. At the same time, there was a decrease of anxiety in children and adolescents with CCP. No evidence for the effect of the drug on visual-motor skills has been found. The results of the study have demonstrated the high safety profile of pantocalcin when used in pediatric practice.

RESUMEN

This study aimed to investigate symptom reduction via the liposomal nasal spray LipoNasal (LN) in patients with rhinitis sicca. Tolerability and the impact on quality of life were also examined. The same parameters were established in parallel for treatment approaches with Bepanthen (BP) nasal ointment containing dexpanthenol and the Rhinomer (RH) nasal spray containing NaCl. This prospective, controlled, open-label observation study was a multicenter trial. 92 patients with rhinitis sicca were allocated to three arms according to their symptoms: LN: n = 33; BP: n = 32 and RH: n = 27. The study comprised three visits at an interval of 14 days. Efficacy was examined by the Rhinitis Sicca Symptom Score (RSSS) documented daily and at the visits based on an endoscopic evaluation. The nasal spray sensory scale was used to investigate the tolerability. Quality of life (QoL) was measured by means of the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and the "Short Form 12" of the "Impact on Health-Related Quality of Life (HRQL)" questionnaire on general quality of life. Nasal symptoms improved significantly (p = 0.001) under all three treatment approaches, reflected by the reduction in the RSSS and the Endoscopy Sum Score. A comparison of the three groups showed that no therapy was significantly superior to any of the others (p = 0.410). The tolerability of all treatments was good. Concerning the nasal moisturization, LipoNasal was evaluated better than Bepanthen and Rhinomer. Quality of life improved in all groups, but not significantly. The results show good efficacy and tolerability of the liposomal nasal spray compared to generally recognized treatments of rhinitis sicca with dexpanthenol nasal ointment and NaCl nasal spray. LipoNasal therefore constitutes a good treatment for patients suffering from dry nose.

RESUMEN

PURPOSE: More than 80% of patients with breast cancer undergoing postsurgical radiotherapy (RT) will develop radiodermatitis and approximately 10% of these patients show grade 3 lesions. Side effects may reduce the patient's compliance and can be limiting factors to follow RT protocols. Therefore, there is a high need for more effective prophylactic treatments. In this study, a silymarin-based cream (Leviaderm(®)) was tested in comparison to our standard of care (SOC) at the involved site. METHODS: A total of 101 patients were evaluated after breast-conserving surgery followed by RT with 50.4 Gy plus boost 9-16 Gy. Of these, 51 patients were treated with the silymarin-based cream. In addition, 50 patients were documented receiving a panthenol-containing cream interventionally, if local skin lesions occurred. The acute skin reactions were classified according to the RTOG and VAS (Visual Analogue Scale) scores. RESULTS: The median time to toxicity was prolonged significantly with silymarin-based cream (45 vs. 29 days (SOC), p < 0.0001). Only 9.8% of patients using silymarin-based cream showed grade 2 toxicity in week 5 of RT in comparison to 52% with SOC. At the end of RT, 23.5% of patients in the silymarin-based study group developed no skin reactions vs. 2% with SOC, while grade 3 toxicity occurred only in 2% in the silymarin-based arm compared to 28% (SOC). CONCLUSIONS: Silymarin-based cream Leviaderm(®) may be a promising and effective treatment for the prevention of acute skin lesions caused by RT of breast cancer patients. To confirm the results of this nonrandomized, observational trial, this component should be tested in larger multicenter studies in this setting.
