RESUMO

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.

RESUMO

OBJECTIVE: Colistin is a potent antibiotic which is mainly preferred in the treatment of multidrug-resistant (MDR) gram-negative bacilli. However, due to the increased risk of acute kidney injury following its use, the clinical application is limited. This nephrotoxicity is known to be induced by oxidative stress and related inflammation. In this study on rats, potent antioxidants Dexpanthenol (DEX) and Ascorbic acid (Vit C) have been administered in combination with Colistin to find out whether they would weaken Colistin's nephrotoxic effects. MATERIALS AND METHODS: Inflammation biomarkers were studied with enzyme-linked immunosorbent assay (ELISA) kits, and oxidative stress biomarkers were studied with different photometric methods in blood and tissue samples taken after treatment with DEX and Vit C in rats with colistin nephrotoxicity. In addition, inflammation and necrosis in the kidney tissues were examined pathologically. RESULTS: It has been observed in the serum and tissue samples that DEX and Vit C decrease oxidative stress and inflammation biomarkers, therefore acting as nephroprotective agents. CONCLUSIONS: These compounds have been found to ameliorate the nephrotoxic effects of Colistin, which were demonstrated in the rats treated with Colistin, as well as the combinations.

RESUMO

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.

RESUMO

This study determined if supplementation with pantothenic acid (PA) for 16 weeks could increase skeletal muscle coenzyme A (CoASH) content and exercise performance. Trained male cyclists (n = 14) were matched into control or PA (6 g·day-1) groups. At 0, 4, 8, and 16 weeks, subjects performed an incremental time to exhaustion cycle with muscle biopsies taken prior to and following exercise. Prolonged PA supplementation did not change skeletal muscle CoASH and acetyl-CoA contents or exercise performance. Novelty: Supplementation with pantothenic acid for 16 weeks had no effect on skeletal muscle CoASH and acetyl-CoA content or exercise performance in trained male cyclists.

RESUMO

AIMS: Pantothenic acid (PA) has been applied to treat alopecia, but the underlying mechanism is still unclear. Our study aims to explore the underlying mechanism of PA in regulating hair follicle (HF) growth. MAIN METHODS: Mink HFs and dermal papilla (DP) cells were isolated and cultured in vitro. HFs and DP cells were treated with 0, 10, 20, 40 µg/ml PA. The effect of PA on HF growth, DP cell proliferation, cell cycle distribution, cell migration, and insulin-like growth factor-1 (IGF-1) and vascular endothelial growth factor (VEGF) expressions in DP cells was measured. Moreover, the effect of PA on inhibitor of DNA binding 3 (ID3)/Notch signaling pathway was analyzed. Subsequently, ID3 was silenced to validate whether ID3/Notch signaling pathway was involved in regulating DP cell proliferation by PA. KEY FINDINGS: Both 20 µg/ml and 40 µg/ml PA promoted HF growth, G1/S transition of DP cells and IGF-1 and VEGF expressions in DP cells, while only 20 µg/ml PA promoted cell viability and the migration of DP cells. Thus 20 µg/ml PA was chosen for the following experiments. PA treatment was found to up-regulate ID3 expression but down-regulate Notch receptor 1 (Notch1) and Notch signaling targets expressions. Furthermore, ID3 knockdown reversed PA-induced cell proliferation and inhibition of Notch1 and Notch signaling targets expressions, indicating that PA-induced DP cell proliferation and inhibition of Notch signaling were mediated via up-regulation of ID3. SIGNIFICANCE: This study provides an underlying mechanism related to the effect of PA on stimulating DP cell proliferation.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: In this study, the authors aimed to research the histopathologic effects of intraurethral use of dexpanthenol for hypospadias repair. Dexpanthenol is a derivative of pantothenic acid, a B complex vitamin. Pantothenic acid is a molecule contributing in the structure of coenzyme A. It decreases the release of myeloperoxidase from granulocytes and inhibits the formation of free oxygen radicals, and it exhibits an anti-inflammatory effect by increasing mitotic activity. OBJECTIVE: The objective of this study is to evaluate the use of dexpanthenol after a tubularized incised plate urethroplasty (TIP) on wound healing, inflammation, and fibrosis. STUDY DESIGN: In this study, 18 healthy male New Zealand white rabbits weighing 2500-3000 g were used. The 18 rabbits were randomly divided into 3 groups. For the hypospadias model, rabbits had a urethral catheter inserted in the urethra and a ventral midline incision was made from the glans tip to the central line of the penis. Afterward, the incision was closed with Vicryl (7/0) using the continuous suture technique, and urethroplasty was completed. For fourteen days, group I had 0.9% saline solution administered intraurethrally twice per day with a 22G catheter sleeve (control group), group II had one dose of 500 mg/kg dexpanthenol (Bepanthene®; Bayer Turk Chemical Industry Limited Company, Turkey) ampoule and one dose of saline solution administered in the same way, and group III had two doses of 500 mg/kg dexpanthenol ampoule administered. On the fifteenth day, the penis was degloved and rabbits had penectomy performed with samples sent to the pathology department for histopathological assessment. RESULTS: The degree of fibrosis and inflammation in group I (control group) was more severe than groups II and III. The differences between groups I and II were statistically significantly different for both fibrosis and inflammation (P = 0.018 and P = 0.041, respectively). The differences between groups I and III were also statistically significantly different for both fibrosis and inflammation (P = 0.019 and P = 0.011, respectively). Groups II and III were not different significantly for fibrosis and inflammation (P > 0.05). DISCUSSION: This study shows that intraurethral dexpanthenol application has positive effects on fibrosis and inflammation. The main limitations of the study are that the hypospadias model was created surgically and long-term follow-up for fistula formation was not assessed. CONCLUSIONS: Administration of intraurethral dexpanthenol after hypospadias repair has positive effects on fibrosis and inflammation.

RESUMO

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.

RESUMO

PURPOSE: To investigate the effects of over-the-counter products on the healing of denture-induced ulcerations and patients' self-reported pain. MATERIALS AND METHODS: A total of 140 patients with acute denture-induced ulcerations were randomized into seven treatment groups: denture grinding (control); topical application of corn oil gel (placebo); triester glycerol oxide gel; D-panthenol gel; D-panthenol mouthwash; L-arginine mouthwash; and hyaluronic acid gel. Healing and self-reported pain were assessed after 1, 3, and 7 days of treatment. RESULTS: The percentage of healed lesions in the mandible and maxilla after 7 days was 67% and 65%, respectively. The only significance in healing was for mandibular lesions at 3 days after application of L-arginine mouthwash; at this period, the healing rate was significantly higher than d-panthenol gel, d-panthenol mouthwash, and hyaluronic acid gel (P < .05). CONCLUSION: Denture grinding as the current protocol for acute denture-induced ulcerations should remain as the default.

RESUMO

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.

RESUMO

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.

RESUMO

Nasal blockage is the most bothersome symptom of acute rhinitis. Nasal decongestant sprays containing alpha-sympathomimetics, such as oxymetazoline and xylometazoline, have a rapid onset of action. However, this effect decreases with repeated application and, furthermore, the ciliary function of the nasal mucosa is practically paralyzed. Dexpanthenol promotes cell proliferation and protects the epithelium. Combining these two agents has demonstrated beneficial synergetic effects on the symptoms of acute rhinitis. In a post hoc analysis of a large-scale double-blind, active-controlled study including 152 patients, we could demonstrate that the benefit of added dexpanthenol appears as early as on the third day of the combined application of xylometazoline and dexpanthenol in terms of complete or near-to-complete freedom from symptoms. After 5 days, 47% of the patients were cured under the combined treatment compared with only 1% under xylometazoline monotherapy. These data show that the addition of dexpanthenol to an alpha-sympathomimetic nasal spray not only improves its tolerability but also further increases its effectiveness and leads to expedited cure.

RESUMO

An adult diabetic male with three toes amputated on his right foot presented with an ulcer infection on his left foot, unresponsive to conventional antifungal oral medication for over two months. The ulcerated foot wound had a large impairment on the patient's quality of life, as determined by the Wound-QoL questionnaire. The compounding pharmacist recommended and the physician prescribed two topical compounded medicines, which were applied twice a day, free of charge at the compounding pharmacy. The foot ulcer infection was completely resolved following 13 days of treatment, with no longer any impairment on the patient's quality of life. This scientific case study highlights the value of pharmaceutical compounding in current therapeutics, the importance of the triad relationship, and the key role of the compounding pharmacist in diabetes care.

RESUMO

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.

RESUMO

PURPOSE: Two randomized, intra-individual comparison studies were performed in healthy subjects to evaluate the skin moisturization and barrier restoration potential of a new topical panthenol-containing emollient (NTP-CE) (Study 1), and its effect on skin microflora (Study 2). METHODS: In Study 1 (N = 23), two skin areas, one challenged with 0.5% sodium dodecyl sulfate (SDS) solution and one unchallenged, were treated with NTP-CE for 3 weeks. Transepidermal water loss (TEWL), skin hydration, and intercellular lipid lamellae (ICLL) organization were measured at regular intervals during the study. In Study 2 (N = 20), quantitative bacterial cultures were obtained over 6 h from a skin area undergoing wash stress with 10% SDS with subsequent single application of NTP-CE. RESULTS: In Study 1, mean AUC for TEWL reduction from baseline was more pronounced with NTP-CE compared with control (-168.36 vs. -123.38 g/m2/h, p = 0.023). NTP-CE use was also associated with statistically significant improvements in stratum corneum hydration and an increase in mean ICLL length from baseline (day 22: 120.61 vs. 35.85 nm/1000 nm2, p < 0.001). In Study 2, NTP-CE use had no negative impact on bacterial viability. CONCLUSIONS: NTP-CE use has favorable and lasting effects on barrier function and repair as well as skin hydration without negatively influencing bacterial viability.

RESUMO

AIM: To study the efficacy of pantogam syrup 10% (hopantenic acid) in the treatment of breath-holding spells (BHS). MATERIAL AND METHODS: Sixty children, aged from 2 to 4 years, with BHS were studied. The evaluation of clinical manifestations and anxiety level was performed. Results of neurophysiological examination (long-term video-EEG-monitoring) were analyzed. Children were divided into 2 groups: main, in which the patients received pantogam syrup, and control group, in which only psychological methods were used. RESULTS AND CONCLUSION: The results of the clinical and neurophysiological studies performed after the treatment, showed the clinical improvement in 73.3% of patients of the main group compared with similar data from the children in the control group (16.7%). The anxiety level significantly decreased after the neuroprotective therapy. A comparative analysis of electroencephalographic indicators demonstrated a significant (р<0.05) reduction in the power range of slow rhythms and manifestations of functional immaturity of the brain in patients of the main group. These results give evidence for the high efficacy of pantogam syrup in the treatment of children with BHS.
