Ocoxin as a complement to first line treatments in cancer.

Chemotherapy and radiotherapy are the most frequent treatment for patients suffering from malignant progression of cancer. Even though new treatments are now being implemented, administration of these chemotherapeutic agents remains as the first line option in many tumor types. However, the secondary effects of these compounds represent one of the main reasons cancer patients lose life quality during disease progression. Recent data suggests that Ocoxin, a plant extract and natural compound based nutritional complement rich in antioxidants and anti-inflammatory mediators exerts a positive effect in patients receiving chemotherapy and radiotherapy. This mixture attenuates the chemotherapy and radiotherapy-related side effects such as radiation-induced skin burns and mucositis, chemotherapy-related diarrhea, hepatic toxicity and blood-infection. Moreover, it has been proven to be effective as anticancer agent in different tumor models both in vitro and in vivo, potentiating the cytotoxic effect of several chemotherapy compounds such as Lapatinib, Gemcitabine, Paclitaxel, Sorafenib and Irinotecan. The aim of this review is to put some light on the potential of this nutritional mixture as an anticancer agent and complement for the standard chemotherapy routine.

Optimal Support of Wound Healing: New Insights.

BACKGROUND: The ultimate goal of wound healing following minor injury is to form a tissue regenerate that has functionality and visual appearance as close to the original skin as possible. The body's physiological response to any wound is traditionally characterised by three distinct steps: inflammation, proliferation and remodelling. SUMMARY: New insights suggest that the three phases overlap (and even occur in parallel) in both time and space in the wound, necessitating a clinical approach that targets each stage simultaneously to ensure rapid repair and wound closure without further complications. Ingredients that exhibit activity across each of the three phases, such as dexpanthenol, are of value in the context of minor wound care and scar management. Key Messages: In addition to treatment and ingredient selection, it is also important to consider broader clinical best practices and self-care options that can be used to optimise the management of minor wounds. An individualised approach that can account for a patient's unique requirements and preferences is critical in achieving effective wound recovery.

Clinical and in vitro evaluation of new anti-redness cosmetic products in subjects with winter xerosis and sensitive skin.

OBJECTIVE: To demonstrate the in vitro activities of panthenol, palmitoylethanolamide (PEA), and niacinamide (NAM) and determine the biophysical properties, clinical safety, tolerability together with efficacy of two developmental anti-redness (AR) formulations containing these ingredients, in alleviating facial redness associated with winter xerosis in healthy volunteers with sensitive skin. METHODS: The anti-inflammatory and skin protective properties of panthenol, PEA and NAM were evaluated in vitro. The physical properties of the AR formulations were analysed using measurement of water vapour transport rate (WVTR) and infrared spectroscopy. Clinical studies were performed between the months of December and April (2014-2015) with efficacy assessed during the winter. Facial redness, irritation, sensitization potential, photo-irritation, and photo-sensitization were evaluated. Self-assessed adverse reactions were reported in diaries of use. RESULTS: Panthenol and PEA reduced prostaglandin E2 , interleukin-6, and thymic stromal lymphopoietin levels in vitro, while NAM induced nicotinamide adenine dinucleotide (NAD) levels and the keratinocyte differentiation markers: filaggrin (2-fold increase, P < 0.001), loricrin (2-fold increase, P < 0.05), involucrin (2 fold increase, P < 0.001) & peroxisomal proliferator activated receptor-alpha (1.5 fold increase, P < 0.05). The two AR products exhibited low WVTR vs. no treatment (P < 0.001) and displayed an ordered lipid structure. The day cream formulation protected against ultraviolet B radiation in vitro. A total of 382 participants were included in clinical studies which showed the AR formulations significantly improved facial redness associated with winter xerosis (Day 29 mean change from baseline: AR day cream 0.77 (P < 0.001); AR serum 0.67 (P < 0.001)). No irritation, sensitization, photo-irritation, photo-sensitization or product-related adverse reactions were observed or reported in the clinical studies. CONCLUSION: The new products significantly improved skin redness associated with winter xerosis in participants with self-perceived sensitive skin. Both products were well tolerated with a suitable safety profile for topical use in subjects with sensitive skin.

OBJECTIF: Démontrer l'activité in vitro du panthénol, du palmitoyléthanolamide (PEA), et du nicotinamide (NAM) et déterminer les propriétés biophysiques, la sécurité clinique, la tolérance ainsi que l'efficacité de deux formulations anti-rougeurs (AR) en développement contenant ces ingrédients pour atténuer les rougeurs faciales associées à la xérose hivernale chez des volontaires sains présentant une peau sensible. MÉTHODES: Les propriétés anti-inflammatoires et protectrices du panthénol, du PEA et du NAM ont été évaluées in vitro. Les propriétés physiques des formulations AR ont été analysées en mesurant le taux de transport de vapeur d'eau (WVTR) et par spectroscopie infrarouge. Des études cliniques ont été réalisées entre décembre et avril (2014-2015) et l'efficacité a été évaluée pendant l'hiver. Les rougeurs, l'irritation, le potentiel de sensibilisation, la photo-irritation et la photosensibilisation au niveau du visage ont été évalués. Des effets indésirables auto-évalués ont été signalés dans des journaux d'utilisation. RÉSULTATS: Le panthénol et le PEA ont réduit les niveaux de prostaglandine E2 , d'interleukine-6 et de lymphopoiétine stromale thymique in vitro, tandis que le NAM a généré une augmentation des taux de nicotinamide adénine dinucléotide (NAD) et des marqueurs de différenciation kératinocytaire : filaggrine (multiplication des taux par 2, P < 0,001), loricrine (multiplication des taux par 2, P < 0,05), involucrine (multiplication des taux par 2, P < 0,001) et du récepteur alpha activé de la prolifération peroxysomale (multiplication des taux par 1,5, P < 0,05). Les deux produits antirétroviraux présentaient un faible taux de WVTR par rapport à l'absence de traitement (P < 0,001) et présentaient une structure lipidique ordonnée. La formulation de la crème de jour protège contre le rayonnement ultraviolet B in vitro. Un total de 382 participants ont été inclus dans les études cliniques qui ont montré que les formulations AR amélioraient significativement les rougeurs faciales associées à la xérose hivernale (changement moyen du jour 29 par rapport à la référence : crème de jour AR 0,77 (P < 0,001) ; sérum AR 0,67 (P < 0,001)). Aucune irritation, sensibilisation, photo-irritation, photosensibilisation ni effet indésirable lié au produit n'a été observé ou signalé dans les études cliniques. CONCLUSION: Les nouveaux produits ont considérablement amélioré la rougeur de la peau associée à la xérose hivernale chez les participants présentant une peau sensible auto-perçue. Les deux produits ont été bien tolérés avec un profil de sécurité approprié pour un usage topique chez les sujets présentant une peau sensible.

Accelerated wound healing with a dexpanthenol-containing ointment after fractional ablative CO2 laser resurfacing of photo-damaged skin in a randomized prospective clinical trial.

Background: Laser therapy with an ablative CO2 laser is a prominent treatment option for photo-damaged skin. The healing process and therefore the success of a laser can be supported by an appropriate postoperative treatment of the laser-treated skin. Objective: The effect of a dexpanthenol-containing ointment with petroleum jelly on wound healing after fractional ablative CO2 laser therapy of photo-damaged skin. Methods: A total of 38 patients with photo-damaged skin received fractional ablative CO2 laser treatment. Occlusive wound care was conducted for a period of 7 days. The complete wound area was divided into two sections: one that was treated with a dexpanthenol-containing ointment and a section that was treated with petroleum jelly. This study had three primary outcome measures: (1) Overview images as well as dermatoscopic images of the laser treated skin were taken immediately after laser treatment and on days 1, 2, 5 and 14 (study visits). Dermatoscopic images were analysed to determine changes of the diameter of the individual lesions between the study visits. (2) Wound-healing rate was visually assessed, based on the measure of re-epithelialization. (3) Cosmetic results were evaluated during study visits by patients and physicians applying a visual analogue scale (VAS). Results: Measuring the diameter of laser-generated lesions revealed a significantly faster cure of the lesions in wound sections that were treated with the dexpanthenol-containing ointment on days 1 and 2, in comparison to the lesions that were treated with petroleum jelly. Concordantly, visual evaluation of the wounds revealed significantly better cosmetic results and re-epithelialization on days 1, 2 and 5 after laser treatment in wound sites that were treated with the dexpanthenol-containing ointment. All patients exhibited a completed wound healing on day 14 after laser treatment. Conclusion: In this comparative study, post-operative treatment of laser-treated skin with a dexpanthenol-containing ointment led to a significantly faster wound closure in comparison to petroleum jelly, especially during the early phase of wound healing. Moreover, assessment of the cosmetic result exhibited beneficial effects of the dexpanthenol-containing ointment in the post-operative wound care after laser treatment. These results emphasize that the use of a dexpanthenol-containing ointment in the post-operative phase following CO2 laser therapy could be a promising alternative to the routinely used treatment with petroleum jelly.

Film wound dressing containing dexpanthenol - preparation and evaluation.

Currently, a wide variety of wound dressings of varying composition and effects is used to treat wounds. These include also film dressings where one of the promising materials for its preparation is sodium carboxymethylcellulose (NaCMC) as a material of natural origin with excellent film-forming properties. Its application is particularly in the field of absorbent dressings, films for wounds from this material are not used in practice yet. Hidden potential offers also dexpanthenol, a substance widely used in dermatological practice. Therefore, the aim of this research was to prepare films from textile NaCMC with dexpanthenol by the solvent evaporation method and their subsequent physicochemical evaluation. The presence of microfibrillar fibers of partially substituted carboxymethylcellulose together with HCMC has ensured optimal parameters for wound application such as pH, swelling and mechanical properties. The films showed satisfactory mass content uniformity and those with dexpanthenol also drug content uniformity.

Effects of rumen-protected pantothenate supplementation on lactation performance, ruminal fermentation, nutrient digestion and blood metabolites in dairy cows.

BACKGROUND: Lactation performance of dairy cow has considerably increased with animal breeding and management improvement in recent years. Ruminal net synthesised pantothenic acid is insufficient to meet the requirement of high producing dairy cows. The objective was to investigate the effects of rumen-protected pantothenate (RPP) on lactation performance, ruminal fermentation, nutrient digestion and blood metabolites in dairy cows. RESULTS: Dry matter (DM) intake tended to increase, whereas milk yields, milk fat percentage and yield, body condition score (BCS) changes and net energy output except for maintenance increased linearly with increasing RPP supplementation. Ruminal pH and ammonia N concentration tended to decrease, total VFA tended to increase, while acetate-to-propionate ratio increased linearly with increasing RPP supplementation. Digestibilities of DM, organic matter and crude protein increased linearly, but neutral detergent fibre and acid detergent fibre digestibility tended to increase. Blood glucose, total protein, non-esterified fatty acids, pantothenic acid, pantothenate kinase, succinyl CoA, acyl carrier protein and acetyl CoA also increased linearly with increasing RPP supplementation. CONCLUSION: The results indicated that supplementary RPP improved lactation performance, nutrient digestion and blood parameters in a dose-dependent manner, and the optimal dose was 12 g RPP per cow per day in the current study. © 2017 Society of Chemical Industry.

Mutations in SLC5A6 associated with brain, immune, bone, and intestinal dysfunction in a young child.

The human sodium-dependent multivitamin transporter (hSMVT) is a product of the SLC5A6 gene and mediates biotin, pantothenic acid, and lipoate uptake in a variety of cellular systems. We report here the identification of mutations R94X, a premature termination, and R123L, a dysfunctional amino acid change, both in exon 3 of the SLC5A6 gene in a child using whole genome-scanning. At 15 months of age, the child showed failure to thrive, microcephaly and brain changes on MRI, cerebral palsy and developmental delay, variable immunodeficiency, and severe gastro-esophageal reflux requiring a gastrostomy tube/fundoplication, osteoporosis, and pathologic bone fractures. After identification of the SLC5A6 mutations, he responded clinically to supplemental administration of excess biotin, pantothenic acid, and lipoate with improvement in clinical findings. Functionality of the two mutants was examined by 3H-biotin uptake assay following expression of the mutants in human-derived intestinal HuTu-80 and brain U87 cells. The results showed severe impairment in biotin uptake in cells expressing the mutants compared to those expressing wild-type hSMVT. Live cell confocal imaging of cells expressing the mutants showed the R94X mutant to be poorly tolerated and localized in the cytoplasm, while the R123L mutant was predominantly retained in the endoplasmic reticulum. This is the first reporting of mutations in the SLC5A6 gene in man, and suggests that this gene is important for brain development and a wide variety of clinical functions.

The long-term relationship between dietary pantothenic acid (vitamin B5) intake and C-reactive protein concentration in adults aged 40 years and older.

BACKGROUND AND AIMS: Low-grade inflammation, represented by minor C-reactive protein (CRP) elevation, has a critical role in the early stages of atherosclerosis, and pantothenic acid (PA) may have an antioxidant effect in inflammatory process. However, the long-term relationship between PA intake and CRP has not yet been studied. The objective of the present study was to evaluate the long-term relationship of PA intake to CRP concentration in healthy adults aged 40 years or older living in a rural area of South Korea. METHODS AND RESULTS: A total of 908 subjects (349 men, 559 women) with repeated data on dietary PA intake and CRP concentration were included in the final analysis. To represent the long-term effect of PA intake, both PA intake at the baseline and average PA intake were used as the exposure, and CRP concentration at the third visit and its change from the baseline to the third visit were used as the outcome. After adjustment for potential confounders, a significant inverse relationship between PA intake and CRP concentration at the third visit was observed (P for trend = 0.001, ß = -0.07 (P-value = 0.001) for PA baseline; P for trend = <0.0001, ß = -0.11 (P-value = 0.0004) for PA average (baseline, 2nd, 3rd)). Higher PA intake was significantly related to lower or attenuated increase in CRP concentration (P for trend = 0.002, ß = -0.24 (P-value = 0.002) for PA baseline; P for trend = 0.001, ß = -0.35 (P-value = 0.001) for PA average (baseline, 2nd, 3rd)). CONCLUSIONS: In conclusion, dietary PA intake was inversely related to subsequent CRP concentration in both men and women aged 40 years or older in South Korea.

Comparative study between excimer light and topical antioxidant versus excimer light alone for treatment of vitiligo.

BACKGROUND: Vitiligo is an acquired idiopathic cutaneous disease characterized by pearly white patches of variable shapes and sizes. Various medical and surgical therapeutic options have been proposed to achieve repigmentation; phototherapy is one of the most efficient options. Topical therapies have been a mainstay of vitiligo treatment, with or without phototherapy. AIM OF THE WORK: To compare the efficacy of combined topical antioxidant hydrogel and excimer light versus excimer light alone in treating vitiligo. PATIENTS AND METHODS: Thirty patients were included in this comparative, prospective, randomized study. For each patient, at least 2-4 vitiliginous macules were randomly selected and treated while an untreated vitiliginous macule served as control. Lesions were divided into two groups: Group A received combination therapy of daily topical antioxidant plus excimer light, while Group B received only excimer light. Lesions were treated twice a week for a maximum of 24 sessions. Initial fluencies were adjusted individually according to the minimal erythema dose in vitiliginous skin. Efficacy based on repigmentation percentages were blindly evaluated by two independent physicians. RESULTS: Group A lesions showed significant efficacy than group B (p < 0.001), specially on treating UV-sensitive lesions with no side effects. CONCLUSION: Topical antioxidant and excimer light represents a valuable, effective therapy for localized vitiligo.

The Uncommon Localization of Herpes Zoster.

INTRODUCTION: Herpes zoster is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus (VZV) that is the cause of varicella. It is an acute neurological disease which can often lead to serious postherpetic neuralgia (PHN). Different nerves can be included with the skin rash in the area of its enervation especially cranial nerves (CV) and intercostal nerves. CASE REPORT: In this report we present a patient with herpes zoster which involved ulnar nerve with skin rash in the region of ulnar innervations in women with no disease previously diagnosed. The failure of her immune system may be explained by great emotional stress and overwork she had been exposed to with neglecting proper nutrition in that period. CONCLUSION: Herpes zoster may involve any nerve with characteristic skin rash in the area of its innervations, and failure in immune system which leads reactivation of VZV may be caused by other factors besides the underlying illness.

Dietary pantothenic acid depressed the gill immune and physical barrier function via NF-κB, TOR, Nrf2, p38MAPK and MLCK signaling pathways in grass carp (Ctenopharyngodon idella).

This study explored the effects of pantothenic acid (PA) on the immune and physical barrier function, and relative mRNA levels of signaling molecules in the gill of grass carp (Ctenopharyngodon idella). The results indicated that compared with optimal PA supplementation, PA deficiency (1.31 mg/kg diet) decreased gill interleukin 10, transforming growth factor ß1, inhibitor of κBα (IκBα), eIF4E-binding protein 2, Claudin b and ZO-1 mRNA levels; anti-superoxide anion activity, and activities and mRNA levels of copper/zinc superoxide dismutase, manganese superoxide dismutase, glutathione peroxidase, glutathione reductase and NF-E2-related factor (P < 0.05). Additionally, PA deficiency and excess (75.08 mg/kg diet) decreased gill complement 3 and glutathione contents, lysozyme and acid phosphatase, anti-hydroxy radical, catalase and glutathione S-transferases activities, and liver-expression antimicrobial peptide 2, hepcidin, Claudin 3, Claudin c and Occludin mRNA levels (P < 0.05). Conversely, PA deficiency increased gill reactive oxygen species and protein carbonyl contents, and interferon γ2, interleukin 8, nuclear factor kappa B P65, Claudin 15a, Kelch-like ECH-associating protein 1a and Kelch-like ECH-associating protein 1b mRNA levels (P<0.05). Moreover, PA deficiency and excess increased gill malondialdehyde content, and tumor necrosis factor α, interleukin 1ß, IκB kinase α, IκB kinase ß, IκB kinase γ, target of rapamycin and ribosomal S6 protein kinase1 p38 mitogen-activated protein kinases and myosin light-chain kinase mRNA levels (P<0.05). In conclusion, PA deficiency decreased immune and physical barrier function, and regulated relative mRNA levels of signaling molecules in fish gill. Based on the quadratic regression analysis of gill lysozyme activity, the optimal PA levels in grass carp (253.44-745.25 g) were estimated to be 36.97 mg/kg diet.

Effects of a Preparation Containing Pantogam, Succinic Acid, and Chitosan on Activities of the Glutathione System and NADPH-Generating Enzymes in Rat Tissues under Conditions of Cerebral Ischemia/Reperfusion.

Treatment with the complex preparation containing pantogam, succinic acid, and chitosan normalized the concentration of reduced glutathione and activities of glutathione peroxidase, glutathione reductase, and some NADPH-generating enzymes (glucose-6-phosphate dehydrogenase and NADPH-isocitrate dehydrogenase) in animals with experimental hypoxia/reperfusion of the brain. These results can be explained by suppression of free radical oxidation and normalization of the antioxidant system related to the neuroprotective, antihypoxic, and antioxidant properties of these substances, their involvement into the regulation of cell metabolism under pathological conditions accompanied by oxidative stress.

[Corneal protection in contact lens users].

PURPOSE: To evaluate the efficacy of corneoprotective agents (Corneregel and Solcoseryl) in contact lens users. MATERIAL AND METHODS: A total of 66 long-term contact lens wearers with dry eye symptoms and varying degrees of corneal epitheliopathy were monitored. All patients used artificial tears, which, however, were not effective enough to suppress manifestations of corneal epitheliopathy and to release the associated discomfort. The therapy was supplemented with Corneregel. The following examination methods were applied: biomicroscopy with fluorescent staining, Norn test, Schirmer's test, advanced tearscopy with digital image analysis of the precorneal tear film lipid layer, corneal confocal microscopy. In all cases the assessment was performed prior to starting Corneregel and repeated in 7 days, 14 days and 1 month. RESULTS: Complete corneal re-epithelization and restoration of the most superficial layer of the epithelium were achieved within 7-14 days. In case of severe initial epitheliopathy the effect of Corneregel was not sufficient and epithelium defects remained. These patients additionally received Solcoseryl Eye Gel. After the treatment course the condition of corneal epithelium ameliorated and contact lens wearing comfort increased. A longer precorneal tear film break-up time indicated an increase of tear film stability. The total tear production did not change significantly. The moistening effect of Corneregel and low-viscosity artificial tears together with intensive regeneration of corneal epithelium enables structural recovery of the epithelial membrane and considerable improvement of the anterior corneal stroma. CONCLUSION: At the first stage of corneoprotective treatment it is appropriate to use preservative-free artificial tears of low and high viscosity. If the effect of tear substitutive therapy is unsatisfactory it is recommended to prescribe Corneregel and Solcoseryl. The regimen is to be adjusted individually.

Efficacy and safety of a panthenol-enriched mask for individuals with distinct impaired skin barrier subtypes.

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.

Efficacy of dexpanthenol for pediatric post-tonsillectomy pain and wound healing.

OBJECTIVES: We evaluated the efficacy of dexpanthenol in managing pediatric post-tonsillectomy pain and wound healing and sought to discover which of two surgical tonsillectomy techniques provides better healing and less postoperative pain. METHODS: One hundred twenty patients who underwent tonsillectomy were equally randomized to thermal welding and cold dissection groups. Dexpanthenol pastilles were given to half of each group. Postoperative throat pain was determined with a visual analog scale on the 1st, 3th, 7th, and 14th days, and mucosal healing patterns were assessed on the 7th and 14th days. RESULTS: Regardless of surgical technique, post-tonsillectomy throat pain was significantly less in the dexpanthenol groups than in the placebo groups (p < 0.05), and tonsillar wound healing was significantly better in the dexpanthenol groups than in the placebo groups (p < 0.05). When a comparison was made with regard to surgical technique, wound healing was significantly better in the cold dissection group (p < 0.05), whereas postoperative throat pain was less in the thermal welding group (p < 0.05). CONCLUSIONS: Postoperative administration of dexpanthenol significantly accelerates the wound healing process and decreases tonsillectomy-related pain complaints.

Tolerability and effects on quality of life of liposomal nasal spray treatment compared to nasal ointment containing dexpanthenol or isotonic NaCl spray in patients with rhinitis sicca.

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.

Impact of a childcare centre nutrition program on nutrient intakes in Nunavik Inuit children.

PURPOSE: We assessed the impact of a nutrition program implemented in Nunavik childcare centres on Inuit children's food and dietary intakes. METHODS: Two hundred and forty-five Inuit children (aged 25.0 ± 9.6 months) were recruited between 2006 and 2010 in Nunavik childcare centres. Dietary intakes were assessed using a single 24-hour dietary recall (n=217). We compared participants' energy and nutrient intakes, and the proportions who met iron requirements and Canada's Food Guide - First Nations, Inuit and Métis recommendations, depending on whether or not they attended a childcare centre during the 24-hour dietary reference period. RESULTS: Children who attended a childcare centre on the day of the recall had significantly higher intakes of omega-3 fatty acids, calcium, total iron, bioavailable iron, phosphorus, beta-carotene, folate, pantothenic acid, riboflavin, and vitamin K, while a higher proportion of them met the recommended intake for total and bioavailable iron. The proportion of children who met the recommended servings for vegetables and fruit, grain products, and milk and alternatives was also significantly higher among participants who attended a childcare centre. CONCLUSIONS: The nutrition program was effective at improving these Inuit preschoolers' diet.

Confirmation of the efficacy of vitamin B6 supplementation for McArdle disease by follow-up muscle biopsy.

No effective treatment for McArdle disease exists.We report a Japanese patient with McArdle disease who was treated with vitamin B(6) supplementation (60-90 mg/day). After treatment, increased muscle phosphorylase activity was confirmed by follow-up muscle biopsy (3.8 times higher than pretreatment levels). Increased lactate levels were seen on the forearm exercise test, and regular work activities could be resumed. Vitamin B(6) supplementation can enhance residual phosphorylase activity and improve insufficient anaerobic glycolysis of skeletal muscle.

Comparative trial of 5% dexpanthenol in water-in-oil formulation with 1% hydrocortisone ointment in the treatment of childhood atopic dermatitis: a pilot study.

BACKGROUND: Atopic dermatitis (AD) is a common chronic relapsing disease particularly affecting children. The emollient used for protection of skin barrier function is the standard treatment for patients with AD. Currently, there is a growing interest in the use of nonsteroidal anti-inflammatory agents such as dexpanthenol (vitamin B5) as an alternative treatment. OBJECTIVE: To compare the effectiveness of 5% dexpanthenol (DT) ointment with 1% hydrocortisone (HC) ointment in childhood AD therapy. METHOD: Patients were treated topically with 5% DT ointment on the right side of the body and 1% HC ointment on the other side twice daily for 4 weeks. The clinical responses were evaluated by SCORAD (Scoring Atopic Dermatitis index) with statistical analysis using paired t-test. RESULT: Of the 30 children enrolled, 26 completed the protocol; mean age was 7.19 years. The average baseline SCORAD score of the DT-treated side and the HC-treated side was 30.95 and 30.54, respectively. There was no statistically significant difference in SCORAD score reduction between the 2 agents. The edematous score of the HC-treated side exhibited faster resolution than that of the DT-treated side, with a statistically significant difference at week 1 and without a statistically significant difference at weeks 2 to 4. The lichenification response rate of HC treatment was more rapid than that of DT treatment; however, there was no statistical group difference. No adverse events were observed with either agent. CONCLUSION: The effectiveness of 5% DT ointment is equal to that of 1% HC ointment. DT ointment may be used as alternative treatment in mild to moderate childhood AD therapy.
