Abstract
Doxorubicin (DOX), which is used as a chemotherapeutic agent in the treatment of tumors, has limited use due to its toxicity in various organs and tissues. One of the organs where DOX has a toxic effect is the lung. DOX shows this effect by increasing oxidative stress, inflammation, and apoptosis. Dexpanthenol (DEX), a homologue of pantothenic acid, has anti-inflammatory, antioxidant, and anti-apoptotic properties. Therefore, the purpose of our investigation was to explore how DEX could counteract the harmful effects of DOX on the lungs. Thirty-two rats were used in the study, and 4 groups were formed (control, DOX, DOX + DEX, and DEX). In these groups, parameters of inflammation, ER stress, apoptosis, and oxidative stress were evaluated by immunohistochemistry, RT-qPCR, and spectrophotometric methods. In addition, lung tissue was evaluated histopathologically in the groups. While CHOP/GADD153, caspase-12, caspase-9, and Bax gene expressions increased in the DOX group, Bcl-2 gene expression levels significantly decreased. In addition, changes in Bax and Bcl-2 were supported immunohistochemically. There was a significant increase in oxidative stress parameters and a significant decrease in antioxidant levels. In addition, an increase in inflammatory marker (TNF-α and IL-10) levels was determined. There was a decrease in CHOP/GADD153, caspase-12, caspase-9, and Bax gene expressions and an increase in Bcl-2 gene expression in the DEX-treated group. In addition, it was determined that there was a decrease in oxidative stress levels and inflammatory findings. The curative effect of DEX was supported by histopathological findings. As a result, it was experimentally determined that DEX has a healing effect on oxidative stress, ER stress, inflammation, and apoptosis in lung damage caused by DOX toxicity.

Abstract
Issues of regeneration of the cornea, which is the most vulnerable structure of the eyeball, suffering from various diseases and injuries, burns, when wearing contact lenses and glaucoma, are highly relevant for ophthalmologists. It is also necessary to minimize damage and stimulate corneal epithelization during and after the use of steroidal and non-steroidal anti-inflammatory drugs, antibacterial drugs and antiseptics, which have a cytotoxic effect and often inhibit regeneration processes, potentially even leading to the development of corneal epithelial defects. This review analyzes the effectiveness of a promising drug 5% dexpanthenol in terms of improving the reparative processes and the function of epithelial cells.

Abstract
Here, we demonstrate that the two distinct formulations of our anti-sepsis drug candidate Rejuveinix (RJX), have a very favorable safety profile in Wistar Albino rats at dose levels comparable to the projected clinical dose levels. 14-day treatment with RJX-P (RJX PPP.18.1051) or RJX-B (RJX-B200702-CLN) similarly elevated the day 15 tissue levels of the antioxidant enzyme superoxide dismutase (SOD) as well as ascorbic acid in both the lungs and liver in a dose-dependent fashion. The activity of SOD and ascorbic acid levels were significantly higher in tissues of RJX-P or RJX-B treated rats than vehicle-treated control rats (p < 0.0001). There was no statistically significant difference between tissue SOD activity or ascorbic acid levels of rats treated with RJX-P vs. rats treated with RJX-B (p > 0.05). The observed elevations of the SOD and ascorbic acid levels were transient and were no longer detectable on day 28 following a 14-day recovery period. These results demonstrate that RJX-P and RJX-B are bioequivalent relative to their pharmacodynamic effects on tissue SOD and ascorbic acid levels. Furthermore, both formulations showed profound protective activity in a mouse model of sepsis. In agreement with the PD evaluations in rats and their proposed mechanism of action, both RJX-P and RJX-B exhibited near-identical potent and dose-dependent anti-oxidant and anti-inflammatory activity in the LPS-GalN model of ARDS and multi-organ failure in mice.

Abstract
Post-acne hyperpigmentation (PAH) occurs secondary to acne vulgaris and may cause significant adverse effects. Although may occur in any skin types, PAH has been found to be more common and severe in people with colored skin. This study aimed to assess the effectiveness of combination serum containing galactomyces ferment filtrate (GFF), dexpanthenol, and Centella asiatica for treating PAH. This randomized controlled clinical trial involved Fitzpatrick skin type (FST) IV and V patients with PAH. Subjects were equally divided into treatment group, who received three drops of combination serum twice daily for 8 weeks, and placebo group. The melanin index (MI) and Lightness (L*) score were assessed every 2 weeks. Out of 51 subjects, the L* score of the treatment group in subjects with FST V was significantly higher on the 4th and 6th week compared to the placebo group (P ˂ 0.05). The MI of subjects with FST IV was significantly lower compared to the placebo group after 8 weeks (P ˂ 0.05). The treatment group showed consistent increasing and decreasing trend in L* score and MI, respectively (r ˃ 0.9, P ˂ 0.05). Combination serum containing GFF, dexpanthenol, and C. asiatica may be effective in treating PAH in subjects with colored skin by accelerating lessening of PAH.

Abstract
In cells, phosphorylation of pantothenic acid to generate phosphopantothenic acid by the pantothenate kinase enzymes is the first step in coenzyme A synthesis. Pantothenate kinase 2, the isoform localized in neuronal cell mitochondria, is dysfunctional in patients with pantothenate kinase-associated neurodegeneration. Fosmetpantotenate is a phosphopantothenic acid prodrug in clinical development for treatment of pantothenate kinase-associated neurodegeneration, which aims to replenish phosphopantothenic acid in patients. Fosmetpantotenate restored coenzyme A in short-hairpin RNA pantothenate kinase 2 gene-silenced neuroblastoma cells and was permeable in a blood-brain barrier model. The rate of fosmetpantotenate metabolism in blood is species-dependent. Following up to 700 mg/kg orally, blood exposure to fosmetpantotenate was negligible in rat and mouse, but measurable in monkey. Consistent with the difference in whole blood half-life, fosmetpantotenate dosed orally was found in the brains of the monkey (striatal dialysate) but was absent in mice. Following administration of isotopically labeled-fosmetpantotenate to mice, ~40% of liver coenzyme A (after 500 mg/kg orally) and ~50% of brain coenzyme A (after 125 μg intrastriatally) originated from isotopically labeled-fosmetpantotenate. Additionally, 10-day dosing of isotopically labeled-fosmetpantotenate, 12.5 μg, intracerebroventricularly in mice led to ~30% of brain coenzyme A containing the stable isotopic labels. This work supports the hypothesis that fosmetpantotenate acts to replace reduced phosphopantothenic acid in pantothenate kinase 2-deficient tissues.

Abstract
The mechanisms by which vitamins regulate immunity and their effect as an adjuvant treatment for tuberculosis have gradually become very important research topics. Studies have found that vitamin B5 (VB5) can promote epithelial cells to express inflammatory cytokines. We aimed to examine the proinflammatory and antibacterial effect of VB5 in macrophages infected with Mycobacterium tuberculosis (MTB) strain H37Rv and the therapeutic potential of VB5 in vivo with tuberculosis. We investigated the activation of inflammatory signal molecules (NF-κB, AKT, JNK, ERK, and p38), the expression of two primary inflammatory cytokines (tumor necrosis factor and interleukin-6) and the bacterial burdens in H37Rv-infected macrophages stimulated with VB5 to explore the effect of VB5 on the inflammatory and antibacterial responses of macrophages. We further treated the H37Rv-infected mice with VB5 to explore VB5's promotion of the clearance of H37Rv in the lungs and the effect of VB5 on regulating the percentage of inflammatory cells. Our data showed that VB5 enhanced the phagocytosis and inflammatory response in macrophages infected with H37Rv. Oral administration of VB5 decreased the number of colony-forming units of H37Rv in lungs of mice at 1, 2, and 4 weeks after infection. In addition, VB5 regulated the percentage of macrophages and promoted CD4+ T cells to express interferon-γ and interleukin-17; however, it had no effect on the percentage of polymorphonuclear neutrophils, CD4+ and CD8+ T cells. In conclusion, VB5 significantly inhibits the growth of MTB by regulating innate immunity and adaptive immunity.

Abstract
The goal of the present study was to develop a new intramammary combination preparation for veterinary use based on silver citrate, arginine and dexpanthenol for the treatment and prophylaxis of subclinical mastitis in cattle. When creating combined medicines for veterinary use, attention must be paid to the factors that influence their stability in a combined presence, and the composition of drugs, as well as the technology for their preparation should be determined. In the current study, a qualitative and quantitative control of model mixtures of active ingredients, as well as of a silver citrate-based combined preparation was carried out. The following parameters that define intramammary drug stability were studied: clarity, pH, and the quantitative content of the active ingredient. Based on the experimental studies, optimal pH limits for a new preparation were determined ranging from 6.4 to 6.7. Considering the instability of solutions based on silver citrate, studies on the stabilization of the preparation were conducted at the obtained pH values. As the result, we used povidone, which possessed the stabilizing properties. The amount of arginine that provides the optimum pH level for the selected combination of active ingredients was also determined. In conclusion, the optimal composition of an intramammary preparation for veterinary medicine in 10 ml ampoules with a shelf life of 6 months was developed.Key words: silver citrate arginine dexpanthenol intramammary dosage form stability.

Abstract
OBJECTIVE Acne vulgaris is a disease of the sebaceous follicle which affects up to 90% of adolescent patients. Topical retinoids, benzoyl peroxide and antibiotics are the main treatments for mild to moderate acne vulgaris. The use of such topical treatments is often associated with local irritation and dryness making the skin more sensitive to the sun. The aim of our study was to assess the efficacy and skin tolerability of a fixed-dose combination therapy with hydrogen peroxide (4%), Salicylic acid (0.5%) and D-panthenol (4%) (HSD) gel, in mild-moderate acne vulgaris, during the period of sun exposure. PATIENTS AND METHODS We retrospectively observed 30 patients of Central Italy with mild to moderate acne between April and September 2012. All the patients selected underwent only therapy with HSD gel once a day in the evening for 60 days, while in the morning they just applied SPF 50 sunscreen. We evaluate the efficacy at 30 and 60 days with the "Global Evaluation Scale" (GES) and the tolerability with a 0-3 qualitative scale. RESULTS The mean GES value showed a statistically significant reduction: 2.03 (SD 0.81) at baseline, 1.63 (SD 0.81) and 0.90 (SD 0.71) respectively at 30 and 60 days (p < 0.01). 21 (70%) and 27 patients (90%) did show good or very good tolerability at 30 and 60 days respectively. CONCLUSIONS Topical treatments with retinoids, antibiotics and antiseptics may increase skin irritation reducing patient adherence to the treatment. HSD gel has shown a good skin tolerability and efficacy in reducing acne lesions, even during the sun exposure period in which traditional treatments should be cautiously used.

Abstract
BACKGROUND Problems affecting the vaginal tract in diabetic women are very often neglected. The efficacy and safety of three gynecological treatments in diabetic women have been assessed. MATERIALS AND METHODS A single-blind randomized progressive trial on 48 diabetic women affected by vaginal dryness, dyspareunia, and recurrent Candida infections was carried out. The ICIQ Vaginal Symptoms (ICIQ-VS) questionnaire was administered. RESULTS The analysis of the parameters of ICIQ-VS questionnaire among the three groups showed significant difference only for "dragging pain" (p = 0.0 19) and "soreness" (p = 0.028). In all groups and for all parameters of the questionnaire, improvement of symptoms was observed. In particular, in Group 1 for all symptoms a highly significant difference was observed, to support the already known benefits of the products and of the proposed combination. Significant improvement was also observed in Group 2. CONCLUSIONS The proposed treatment with DermoXEN® Ultracalming Special for diabetics and DermoXEN® Vitexyl vaginal gel exert effective moisturizing and soothing action. Indeed, the aforementioned products have been proven effective for the main gynecological problems of diabetic women.

Abstract
OBJECTIVES This study investigated whether Dexpanthenol (DEX) improves diabetic cardiovascular function and cardiac performance by regulating total oxidant and antioxidant status. METHODS Diabetes was induced by a single intraperitoneal injection of Streptozocin (50 mg/kg in 1 ml of saline) and treatment groups received DEX (300 mg/kg/day) for 6 weeks. Endothelium (in)dependent relaxation responses were assessed in thoracic aortic rings and coronary vasculature together with alpha receptor and voltage dependant contractile responses of aorta. Myocardial contractility has been recorded by an intra ventricular latex balloon. Total oxidant and antioxidant status were measured from the serum samples. RESULTS Induction of diabetes resulted in an apparent body weight loss, high blood glucose, endothelial dysfunction and increased serum oxidant status. DEX supplementation restored the endothelial dysfunction, antioxidant status and body weight whereas decreasing blood glucose level. CONCLUSION Along with the standard therapy of diabetes, DEX can be used as a safe and economical way of adjuvant therapy to diminish the burden of the disease (Tab. 3, Fig. 3, Ref. 30).

Abstract
Postoperative sore throat (POST) is usually self-limiting but was rated by patients as one of the top 10 most undesirable anesthetic outcomes. Pharmacologic interventions that have been suggested to decrease the incidence of POST include application of local anesthetics and corticosteroids to the cuff of the endotracheal tube. These interventions often require extra steps during induction of general anesthesia. We sought evidence for using nonsteroidal, nonlocal anesthetic, topical pharmacologic interventions conveniently implemented preoperatively to decrease the incidence of POST. One hundred seventeen potential evidence sources were located, with 11 randomized controlled trials meeting inclusion criteria. The evidence examined ketamine, aspirin, and azulene gargle; benzydamine gargle or oral spray; dexpanthenol pastilles; and lozenges containing amyl-m-cresol or magnesium. Although there were methodologic concerns with the studies, the evidence suggested that all the treatment medications decreased the incidence of POST at early and late intervals. The severity of POST was also typically reduced. Preoperative ketamine and aspirin gargle are probably the most promising for providers practicing in the United States. However, before these agents are recommended for general use, large multicenter trials should be done exploring not only efficacy but also dose-response relationships and side effects.

Abstract
OBJECTIVE To objectify indications for treatment with pantogam in premature infants with perinatal hypoxic-ischemic injury of the CNS. MATERIAL AND METHODS We studied 71 children, with GA (gestation age) 24-36 weeks (32,9±2,9 weeks), with perinatal hypoxic-ischemic injury of the CNS, I-II grades, and hyperexitability syndrome. The main group (33 patients) received pantogam in dose 50 mg/kg/day at the adjusted age (AA) 36-40 weeks from the conception. The comparison group included 38 patients. EEG day sleep monitoring was performed before and at the end of treatment. RESULTS Shortening of sleep cycle was observed in 78,8% children of the main group and in 78,9% of the comparison group. Duration of transitional sleep over 1 min was 78,79% and 81,58%. At AA 44-46 weeks, the frequency of sleep disorders decreased to 45,45% (p=0,012) and 52,63% (p=0,05). Duration of transitional sleep over 1 min was 45,45% and 65,79%. Duration of the latent period of the 2nd stage of slow wave sleep was 6,4±2,57 and 12,5±7,18 min (p=0,0004). CONCLUSION The treatment reduced sleep disorders, changed the duration of transitional sleep stage and latent period of the 2nd stage of slow wave sleep.

Abstract
Background Tungiasis, a parasitic skin disease caused by the female sand flea Tunga penetrans, is a prevalent condition in impoverished communities in the tropics. In this setting, the ectoparasitosis is associated with important morbidity. It causes disfigurement and mutilation of the feet. Feasible and effective treatment is not available. So far prevention is the only means to control tungiasis-associated morbidity. Methodology In two villages in Central Madagascar, we assessed the efficacy of the availability of closed shoes and the twice-daily application of a plant-based repellent active against sand fleas (Zanzarin) in comparison to a control group without intervention. The study population was randomized into three groups: shoe group, repellent group and control group and monitored for ten weeks. The intensity of infestation, the attack rate and the severity of tungiasis-associated morbidity were assessed every two weeks. Findings In the repellent group, the median attack rate became zero already after two weeks. The intensity of the infestation decreased constantly during the observation period and tungiasis-associated morbidity was lowered to an insignificant level. In the shoe group, only a marginal decrease in the intensity of infestation and in the attack rate was observed. At week 10, the intensity of infestation, the attack rate and the severity score for acute tungiasis remained significantly higher in the shoe group than in the repellent group. Per protocol analysis showed that the protective effect of shoes was closely related to the regularity with which shoes were worn. Conclusions Although shoes were requested by the villagers and wearing shoes was encouraged by the investigators at the beginning of the study, the availability of shoes only marginally influenced the attack rate of female sand fleas. The twice-daily application of a plant-based repellent active against sand fleas reduced the attack to zero and lowered tungiasis-associated morbidity to an insignificant level. Tungiasis (sand flea disease) is a parasitic skin disease present in many resource-poor communities in South America, the Caribbean and sub-Saharan Africa. In this setting tungiasis is associated with important morbidity. Hitherto, the only effective treatment is the surgical extraction of embedded sand fleas. In the endemic areas this is done using inappropriate sharp instruments and causes more harm than good. The prevention of the infestation is the only option to control morbidity. In this study we show that the twice daily application of a herbal repellent based on coconut-oil (Zanzarin), is highly effective in preventing sand flea disease in a heavily affected community in Madagascar. The attack rate became zero immediately after starting the application of the repellent. The degree of tungiasis associated morbidity approached zero within 10 weeks. In contrast, the availability of closed solid shoes had only a marginal protective effect; although shoes were requested by the villagers and wearing shoes was encouraged by the investigators at the beginning of the study. In a control group from the same village the attack rate, the intensity of infestation and of tungiasis-associated morbidity remained unchanged. Our study in rural Madagascar shows that effective und sustainable morbidity control is possible using a repellent derived from coconut oil.

Abstract
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.

Abstract
UNLABELLED The aim of the study was to assess the possibility and effectiveness of hopaten acid use for early postoperative cognitive dysfunction correction in children of school age. MATERIALS AND METHODS In compliance with inclusion and exclusion criteria, totally 40 children of school age (7-16 years old, ASA status I-II) with surgical pathology: (varicocele, cryptorchidism, inguinal hernia) were included A comperative assessment of neuropsychic status during pre - and postoperative are period in children, operated under propofol-fentanyl total intravenous anesthesia (TIVA) was conducted All patients were randomized to the control (without cepebroprotection 1st group, 20 children) and experimental (using cepebroprotection with hopaten acid within 1 month after the operation, 2nd group, 20 children) groups. Dimension of the study: Harvard standard monitoring, respiratory gas composition, neuropsychic tests (Bourdon test, "10 words test", etc.). RESULTS For full compatibility groups (age, ASA status and anthropometric data, equal operation duration and the equipotential drug dosage adjustment is revealed, that in group of propofol-fentanyl TIVA in the early postoperative period in school age children postoperative cognitive dysfunction (POCD) is developing, which in case of absence of the corresponding correction is maintained after 1 month after operation (at least) in 80% of cases. In the application of hopaten acid cerebroprotection (40 mg/kg per day) severity of POCD reliably is reduced or compensated by the time of discharge from the hospital (3-7-th day when non-traumatic interventions), and 1 month after the operation in 30% of patients experienced improvement of cognitive functions, which proves the effectiveness of hopaten acid for POCD treatment. CONCLUSION In case of propofol-fentanyl TIVA anesthesia in children of school age is indicated preventive prescription of multimodal cerebroprotectors without age limitations (for example hopaten acid (40 mg/kg per day) for POCD treatment.

Abstract
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.

Abstract
OBJECTIVES Post-operative ileus can also occur in other types of surgery not strictly related to abdomen. The objective of this study was to investigate the efficacy of pantothenic acid administration to stimulate intestinal peristalsis in case of post-operative ileus and estimate the most effective dose. This vitamin can be used for the treatment of chronic atonic intestine or for chronic constipation, but therapeutic indications are not precise in these conditions. PATIENTS AND METHODS This pilot study has used patients divided in groups treated in post-operative period with physiological solution for patients in control group (Placebo) and Dexpantenolo, which is a derivative in alcohol of pantothenic acid, for all the actively treated patients. The treatments were administered intravenously during the second and third post-operative day, according to the treatment schedule. RESULTS 60 patients were recruited and they were allocated to five treatment groups or one control group. For males, the median time of the first bowel evacuation was 90 hours while for females the median time was 84 hours (p=0.891). For patients who received a spinal anesthetic, the median time was 72 hours, while for those who received a peridural anesthetic the median time was 96 hours (p=0.571). Between six treatment groups, instead, there is a significant difference between the median times from the operation to the first bowel evacuation (p<0.001). Linear regression model obtained using as outcome evacuation hours after surgery show that only variable which significantly affects time between operation and the first bowel evacuation is treatment dose (Beta = -0.868, p<0.001). DISCUSSION This study would seem to indicate that pantothenic acid is effective for treatment of post-operative intestinal ileus; there is a dose response relationship between pantothenic acid and the decreasing time from surgical operation to first bowel evacuation. However, this study is preliminary; further studies are necessary, preferably randomized and with a larger number of patients.

Abstract
We have analyzed the efficacy of nootropic drug pantogam in the treatment of hyperkinetic disorders in children aged 6-12 years. The results of the randomized placebo-controlled trial demonstrated the decrease of major symptoms of hyperkinetic disorders (inattention, hyperactivity, impulsivity), comorbid mental and behavior disorders, the improvement of cognitive functions in the group of children treated with pantogam during 6 weeks and the absence of significant changes in the placebo group. It has been concluded that pantogam is effective in the treatment of hyperkinetic disorders in children.

Abstract
Efficacy of pantogam active in the complex treatment of facial and cervical dystonic hyperkineses was studied in 37 patients (25 women, 12 men) with dystonic torticollis, blepharospasm, oromandibular dystonia with illness duration more than 6 months. In these patients, the previous treatment had no positive effect. Pantogam active was prescribed in dose 900-1800 mg/day during 12 weeks. Efficacy was assessed with the TWSTRS, the HADS and the CGI-I. Pantogam active as add-on to basic treatment led to the reduction of severity in dystonic hyperkineses on the average 2-2,5 months from baseline. The best effect was seen in patients with short disease duration. The prescription of this drug allowed to increase the dose of drugs traditionally used in treatment of dystonia (clonazepam, cyclodole, tiapridal, baclofen) due to the decrease of their side-effects.

Abstract
The present study comprised two parts. In the first part, authors attempted to work out the systematics of asthenic disorders based on our own observations of 189 children aged 7-14 years. The following clinical variants of asthenic states in children were singled out: cerebrogenic asthenia (14.3%), somatogenic (13.8%), residual (16.4%), dysontogenetic (20.1%) and neurasthenia (35.4%). In the second part, we summarized the results of treatment of neurasthenia with adaptol (32 patients) compared to pantoham (30 patients). The efficacy of adaptol was higher: the improvement was seen in 71.9% of cases compared to pantoham (56.7%). The good tolerability of adaptol which clinical efficacy is confirmed by neurophysiological and psychological studies is discussed.

Abstract
PURPOSE OF REVIEW This review evaluates the efficacy of vitamin supplementations for prevention and treatment of pressure ulcer and surgical wounds on the basis of recent clinical intervention studies. RECENT FINDINGS Intervention studies show that an energy and protein-rich oral nutritional supplement providing high doses of vitamin C and zinc in combination with arginine may prevent the development of pressure ulcers. This measure seems to improve the healing of pressure ulcer, which is questionable for vitamin C alone. For surgical wounds, data from randomized controlled studies are scarce, but results on the use of vitamin C in combination with pantothenic acid are promising. SUMMARY Considerable evidence suggests that supplementation of vitamin C together with zinc by an oral nutritional supplement rich in energy, protein and arginine may be an efficient tool for pressure ulcer healing in contrast to single vitamin C. The evidence for prevention of pressure ulcer by such an oral nutritional supplement is comparably low. This fits also for single vitamin C supplementation in the healing of surgical wounds. Further, well designed and well powered studies on the benefit of antioxidant vitamins for wound healing within a diet providing adequate energy and protein are necessary.

Abstract
Forty-five patients with discirculatory encephalopathy, I-II stages, and moderate cognitive disorders of vascular genesis were examined. All patients were stratified into 2 groups: 25 patients of the main group received pantoham in the complex therapy in dose 250 mg 3 times a day during 2 months; 20 patients of the comparison group received only a unified therapy (antihypertensive drugs and, if necessary, coronarolytics and glucose-decreasing drugs. The clinical/neurological and instrumental examinations and neuropsychological testing were performed before the treatment and after 8 weeks. The subjective improvement of the state of patients treated with pantoham, together with the significant improvement (p < 0.05) in the performance of cognitive tests (a battery of frontal dysfunction tests, the Clock drawing test, generalization ability) was found. No positive changes in the performance of cognitive tests were observed in the comparison group. None of the patients had side-effects that led to a change of the therapeutic scheme.

Abstract
OBJECTIVE To compare the efficacy of dexpanthenol spray and saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery (ESS). MATERIAL AND METHOD One hundred twenty eight sinusitis patients undergoing ESS were randomly allocated to receive dexpanthenol spray (Mar plus) or saline irrigation twice a day for 4 weeks after the operation. Total nasal symptom score, crusting, infection, compliance, and patient satisfaction were evaluated at 1, 2-3, 4-6, and 12 weeks. Mucociliary clearance was assessed with the saccharin test before ESS and at the last visit. One hundred ten patients remained at the present study termination. Chi-square test and Mann-Whitney U test were employed. RESULTS Total nasal symptom score, mucociliary clearance, and infection improved in both groups after the operation. The dexpanthenol group resulted in a better mucociliary clearance than saline irrigation (9.93 +/- 6.04 vs. 12.38 +/- 9.32 min, p = 0.43). Saline irrigation resulted in a greater reduction of post nasal drip than dexpanthenol at the first visit (74% vs. 87%, p = 0.04). Compliance and patient satisfaction were comparable. CONCLUSION The efficacy of dexpanthenol was comparable to nasal saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery. Dexpanthenol is an alternative treatment, which may be useful in young children and complicated cases.

Abstract
Published clinical experience with hamamelis ointment in children is limited. This observational study included children (age 27 days to 11 years) with minor skin injuries, diaper dermatitis, or localized inflammation of skin. The children received either hamamelis ointment or dexpanthenol ointment in groups at a 3-to-1 ratio. Baseline and post-treatment assessments compared the total scores of predefined signs and symptoms for each condition. Physicians and parents were asked for a global assessment of efficacy and tolerability of the respective treatments at the end of therapy. A total of 309 children were treated (hamamelis n = 231; dexpanthenol n = 78). The treatment groups were comparable regarding demographic data and baseline total scores of signs and symptoms. In all three diagnosis groups, the efficacy of hamamelis and dexpanthenol was shown by a statistically significant and clinically relevant decrease of total scores from baseline to endpoint (p < 0.0001 for each group, Wilcoxon signed-rank test). Overall, the results for the hamamelis and the dexpanthenol groups were similar. Descriptive advantages for the hamamelis group were observed for a number of parameters and diagnosis groups. Both treatments were well tolerated. Ratings of the tolerability of hamamelis were "excellent" or "good" in 99.1% (physicians) and 98.2% (parents) of cases, respectively. The corresponding ratings for dexpanthenol were 97.4 and 92.3%. In conclusion, hamamelis ointment is an effective and safe treatment for certain skin disorders in children up to the age of 11 years. The observed effects are similar to dexpanthenol.

Abstract
OBJECTIVE To investigate the effect of the addition of Tonimer gel spray into nasal mucosa care on nasal mucosal findings and patient comfort in the postoperative period of endonasal surgery. MATERIAL AND METHOD 40 patients who underwent endonasal surgery were included in the study. For the postoperative nasal care, isotonic saline was applied to both nasal cavities, and subsequently, Tonimer nasal gel spray was additionally applied to the right nasal cavity. Patients were examined on the 2nd, 7th, and 15th postoperative days. The findings of the examinations were scored with respect to crusting and the patient nasal comfort was assessed using the visual analog scale (VAS). RESULTS The VAS values which measure patient comfort and crusting were significantly lower on the Tonimer side compared to control (p < 0.01). CONCLUSION Tonimer and saline combination was found to be superior to saline per se in decreasing crusting and improving patient nasal comfort in the postoperative period.

Abstract
Despite the prompt diagnosis and treatment of testicular torsion (TT), there are problems with fertility and atrophy after testicular salvage. Dexpanthenol (Dxp) is the biologically active alcohol of pantothenic acid (PA). Dxp is converted to PA in tissues. PA increases the content of reduced glutathione (GSH), Coenzyme A and ATP synthesis in cells. GSH and glutathione-dependent peroxidases (GPX) are the major defense systems against oxidative stress. GPX-4 is the major antioxidant in testicular tissue. However, the activity of GPX-4 appeared and increased only after puberty. We investigated the effect of Dxp on testicular atrophy after TT at the 60th day. Rats were separated randomly into four groups. Group C: control group, group Td: torsion + detorsion, group Sal: torsion + saline + detorsion, group Dxp: torsion + Dxp + detorsion. The left testis was rotated 720 degrees for 2 h. In group Sal, normal saline and in group Dxp, Dexpanthenol were injected intraperitonally, 30 min before detorsion. After 60 days, the testicular weights and volumes were measured. Histopathology of the left testis was evaluated with mean seminiferous tubular diameter (MSTD) and mean testicular biopsy score (MTBS). The left (torsed) testicular weight and volume of groups Td and Sal were significantly lower compared to group Dxp. The MSTD and MTBS of group Td and Sal were significantly lower than group Dxp. Contralateral testicular weight and volume of groups Td, Sal and Dxp had no significant difference compared to the control group. Dxp significantly prevented testicular atrophy after 60 days of TT. Dxp has FDA approval, is safe, cost effective and readily available. Its relevance for clinical trials may especially be for the problem of testicular atrophy catastrophe, seen very frequently following testicular salvage.

Abstract
BACKGROUND In this study, we aimed to compare the effectiveness of dexpanthenol pastille and benzydamine hydrochloride spray on the prevention of a sore throat. METHODS One hundred and eighty patients undergoing general anaesthesia, who were ASA I-II and with their ages ranging between 15 and 70 years, were randomly allocated to three groups, each consisting of 60 patients. For group B, four puffs of benzydamine hydrochloride were sprayed into the mouth initially 30 min before the operation and repeatedly 5 min before anaesthesia induction. For group D, two pastilles of dexpanthenol were administered orally to be sucked 30 min before the operation. For group P, four puffs of distilled water were sprayed into the mouth initially 30 min before the operation. Post-operatively, patients were evaluated for a sore throat for the duration of 24 h. RESULTS The incidence of a sore throat was significantly lower for group D when compared with group B and group P. The incidence of a sore throat was similar for group B and group P. According to the sore throat grading system, the number of patients experiencing no complaints was significantly higher for group D when compared with group B and group P. The number of patients achieving moderate scores was significantly higher for group B when compared with group D. CONCLUSION The administration of 200 mg of dexpanthenol prophylactically before endotracheal intubation is effective in the prevention of post-operative sore throat.

Abstract
AIM Napkin dermatitis or diaper dermatitis is one of the most frequent cutaneous disease in the pediatric age. The most common type of napkin dermatitis is the irritant contact form, which is frequently complicated by an overinfection with bacteria or Candida albicans. METHODS In this paper, 25 children (7 males and 18 females), aged between 1 month and 4 years and affected by napkin dermatitis, were treated with a barrier cream containing zinc oxide, vitamin E, panthenol (NoAll Bimbi Pasta Trattante, PSN Rottapharm, Milan, Italy). In 20 patients, a diagnosis of irritant contact diaper dermatitis was made, 3 patients suffered from atopic dermatitis, 1 patient was affected by psoriasis and 1 patient presented to a perianal streptococcal dermatitis. A candidal overinfection was diagnosed in 12 patients and was treated with a topical antifungal agent, applied twice daily for 2 weeks. NoAll Bimbi Pasta Trattante was applied at every diaper change. In all cases, we considered 2 subjective symptoms (burning and itching), and 3 objective parameters (erythema, oedema, exudation/vesiculation), at baseline and after 4 weeks of treatment. RESULTS One patient withdrew the study. In 13 patients clinical healing was observed, 9 patients showed marked improvement, in 2 patients we did not observe improvement. Tolerability was considered excellent in 13 patients, good in 9 and sufficient in 2. CONCLUSIONS The results obtained demonstrated that NoAll Bimbi Pasta Trattante, applied at every change of the napkin, is very effective and well tolerated in the treatment of irritant diaper dermatitis. Moreover, NoAll Bimbi Pasta Trattante, applied in association with other pharmacological treatments, may accelerate healing in case of overinfection due to Candida albicans and in case of inflammatory dermatoses localized in the gluteo-perineal area.

Abstract
A double-blind, randomized, parallel-group, placebo-controlled study has been carried out in order to evaluate the effect of orally self-administered Slim339, a proprietary fixed combination of Garcinia cambogia extract with calcium pantothenate (standardized for the content of hydroxycitric acid and pantothenic acid) and extracts of Matricaria chamomilla, Rosa damascena, Lavandula officinalis and Cananga odorata, on body weight in overweight and obese volunteers. During a 60-day treatment period, the average reduction in body weight for the group receiving Slim339 (n = 30) was 4.67% compared with 0.63% for the placebo group (n = 28) (p < 0.0001). Weight losses of >or=3 kg were recorded for 23 subjects in the treatment group and only one in the placebo group. It is concluded that Slim339 represents a potential therapy for obesity.

Abstract
Pantogam was used as a corrector of the side-effects of neuroleptic therapy. The adverse effects were assessed psychometrically with several scales. Attention was focused on the unwanted signs (pathological movements of different groups of muscles). Fifty patients were studied, 37 of them completed the treatment course. Pantogam was administered in dosage 750-3000 mg per day along with traditional and atypical neuroleptics. The drug was effective against the most prevalent side-effects. The mild sedative effect of pantogam, absence of negative influence on myocardial vessels and possibility of its combination with most pharmacological drugs make its possible to use the drug in patients of different age groups.

Abstract
BACKGROUND Severity of irritant diaper dermatitis (IDD) from diarrhea varies from patient to patient depending on the nature of feces and the number of bowel movements. The purpose of the present study was to compare the effectiveness of dexpanthenol and zinc oxide ointment with ointment base in the treatment of irritant diaper dermatitis from acute diarrhea in children by measuring transepidermal water loss (TEWL). MATERIAL AND METHOD Forty-six children with diarrhea were prospectively, block randomized, investigator-blinded to receive dexpanthenol and zinc oxide ointment on one side and ointment base on the other side. TEWL was measured before and on days 1, 3, and 7 of treatment together with the assessment of severity score. The efficacy of treatment was defined by complete clearance of the lesion. RESULTS TEWL in the treated and control side was not different before the application of the topical medication. In the present study, the efficacy of 5% dexpanthenol and zinc oxide ointment on D3 was 39% (18from 46 patients) compared to 32% in the ointment base side. On D7, the efficacy of the treated side was 58.7% and the ointment base side was 56%. The patients who still had skin lesions were those who had prolonged diarrhea. On the treated side, the mean of TEWL was lower than the control side on DI (p = 0.18) and had significant improvement on D3 (p = 0. 002). At the end of the present study, TEWL on the treated side was less than TEWL of the control side but it did not have statistical significance (p = 0.07). There was no rash or sign of abnormality on the treated side at the end of D7. CONCLUSION In the treatment of lDD from acute diarrhea, 5% dexpanthenol and zinc oxide ointment significantly decreased TEWL in the treated side more than the ointment base on day 3 but the severity score was not significantly different on days 1, 3 and 7.

Abstract
In utero exposure to valproic acid (VPA) during pregnancy is associated with an increased risk of neural tube defects (NTDs). Although the mechanism by which VPA mediates these effects is unknown, VPA-initiated changes in embryonic protein levels have been implicated. The objectives of this study were to investigate the effect of in utero VPA exposure on embryonic protein levels of p53, NF-kappaB, Pim-1, c-Myb, Bax, and Bcl-2 in the CD-1 mouse. We also evaluated the protective effects of folic acid and pantothenic acid on VPA-induced NTDs and VPA-induced embryonic protein changes in this model. Pregnant CD-1 mice were administered a teratogenic dose of VPA prior to neural tube closure and embryonic protein levels were analyzed. In our study, VPA (400 mg/kg)-induced NTDs (24%) and VPA-exposed embryos with an NTD showed a 2-fold increase in p53, and 4-fold decreases in NF-kappaB, Pim-1, and c-Myb protein levels compared to their phenotypically normal littermates (P<0.05). Additionally, VPA increased the ratio of embryonic Bax/Bcl-2 protein levels (P<0.05). Pretreatment of pregnant dams with either folic acid or pantothenic acid prior to VPA significantly protected against VPA-induced NTDs (P<0.05). Folic acid also reduced VPA-induced alterations in p53, NF-kappaB, Pim-1, c-Myb, and Bax/Bcl-2 protein levels, while pantothenic acid prevented VPA-induced alterations in NF-kappaB, Pim-1, and c-Myb. We hypothesize that folic acid and pantothenic acid protect CD-1 embryos from VPA-induced NTDs by independent, but not mutually exclusive mechanisms, both of which may be mediated by the prevention of VPA-induced alterations in proteins involved in neurulation.

Abstract
OBJECTIVE To review the literature on nipple pain and to delineate effective strategies for the prevention and treatment of nipple pain in breastfeeding mothers. DATA SOURCES Computerized searches on MEDLINE, Pre-MEDLINE, CINAHL, and the Cochrane Library. STUDY SELECTION Articles from indexed journals relevant to the objective were reviewed from January 1983 to April 2004. Preference was given to research-based studies in English. DATA EXTRACTION Data were extracted and organized under two headings: prevention of nipple pain or trauma and treatment of nipple pain or trauma. The Critical Appraisal Form by J. Briggs was used to extract the data from research-based articles. DATA SYNTHESIS The health benefits of breastfeeding for mother and infant are well documented; however, nipple pain is a common reason reported by women for the early termination of breastfeeding. Several studies have compared various treatments for either the prevention of or treatment for nipple pain. These treatments include warm water compresses, tea bag compresses, heat, application of expressed mother's milk, lanolin, vitamin A, collagenase, dexpanthenol, hydrogel therapy, glycerin gel therapy, moist occlusive dressing, education regarding proper latch-on and positioning, and no treatment. CONCLUSIONS No one topical agent showed superior results in the relief of nipple discomfort. The most important factor in decreasing the incidence of nipple pain is the provision of education in relation to proper breastfeeding technique and latch-on as well as anticipatory guidance regarding the high incidence of early postpartum nipple pain.

Abstract
A fundamental issue in regulatory decision making is the assessment of the benefit/risk profile of a compound. In order to do this, establishing the existence of a treatment effect by a significance test is not sufficient, but the clinical relevance of a potential benefit must also be taken into account. A number of regulatory guidelines propose that clinical relevance should be assessed by considering the rate of responders, i.e. the proportion of patients who are observed to achieve an apparently meaningful benefit. In this paper, we present methods for planning clinical trials that aim at demonstrating both statistical and clinical significance in superiority trials. Procedures based on analytical calculations are derived for normally distributed data and the case of a single endpoint as well as multiple primary outcomes. A bootstrap procedure is proposed that can be applied to non-normal data. Application is illustrated by a clinical trial in Alzheimer's disease.

Abstract
Neurotrophic keratopathy is one of the most challenging conditions among the disorders of wound healing of the ocular surface. In addition to bilateral assessment of corneal sensitivity, tear status and lid function must be analyzed and treated by unpreserved artificial tears and adequate lid surgery. Further conservative treatment options include hyaluronic acid and dexpanthenol as well as autologous serum. Application of recombinant growth factors (especially NGF) represents an interesting perspective. Concerning surgical interventions, temporary or permanent occlusion of the lacrimal punctum may be accompanied by lateral tarsorrhaphy which is easy to perform, potentially reversible, and in most cases successful. Depending on the type of wound healing disorder amniotic membrane transplantation may be helpful either as basal membrane transplant (graft) or as a patch, or in combination (sandwich). A tectonic keratoplasty a chaud should typically be combined with a simultaneous amniotic membrane patch and/or a lateral tarsorrhaphy to avoid persistent epithelial defects.

Abstract
Mitochondrial decay due to oxidant byproducts is a principal underlying contributor to aging, including the degenerative diseases of aging such as brain degeneration [15,23,32]. The energy for basic metabolic processes comes from mitochondria, and their decay with age impairs cellular metabolism and leads to cellular decline. Our progress over the last decade in delaying the mitochondrial decay of aging is briefly reviewed.

Abstract
BACKGROUND More than 600 million units of nasal decongestants are sold worldwide annually. The cytotoxic and ciliary toxic potential of decongestants, as well as the preservatives of these products, in particular benzalkonium chloride (BKC), is well established. Recently, a beneficial effect of dexpanthenol on the tolerability of the alpha-sympathomimetic xylometazoline and BKC has been described; however, it was unclear if this effect, resulting in significantly higher cell counts in a cytotoxicity study and an increase in ciliary beat frequency in a ciliary toxicity study was of protective or therapeutic nature. The objective of this study was (a) to evaluate whether dexpanthenol would be a useful additive to nasal decongestants to counter the cytotoxic and ciliary toxic effects of the active ingredient and the preservative and (b) to find out whether this beneficial effect is of protective or therapeutic nature. METHODS Systematic cytotoxic in vitro tests were performed. After exposure to xylometazoline (0.1%), the effect of dexpanthenol (5%) and BKC (0.01%) was determined by placebo-controlled assessment of cell growth in a human amniotic cell line. RESULTS Dexpanthenol significantly reduces the toxic effects of xylometazoline regarding cell growth (p < 0.001) when applied in advance. When BKC is eliminated from the nasal sprays, a further significant increase of cell growth was found (p < 0.001). When dexpanthenol is therapeutically applied after xylometazoline, effects on cell growth are only one-half of those of the protective approach. CONCLUSION The additive application of dexpanthenol (5%) given before nasal decongestants or preserved nasal sprays is able to improve the tolerability of these substances and to counteract the toxic effects.

Abstract
PURPOSE Anesthesia impairs lid closure and decreases tear secretion and stability. Protection may, in principle, be conveyed by manual eye closure, taping the eyelids closed, and by instillation of protective substances into the conjunctival sac. Both hydro-gels and ointments are used in clinical practice. It was the objective of the present study to compare a transparent clear ocular hydro-gel (Vidisic) and a commonly used dexpanthenol and vitamin A (Oleovit) based ointment as examples of these classes of ocular lubricants in their capability to provide perioperative eye comfort. Furthermore, their bacteriostatic properties were assessed in vitro. METHODS Ninety-two consecutive patients undergoing total iv general anesthesia were randomly allocated to receive either ocular dexpanthenol ointment or a clear hydro-gel after induction of anesthesia. Subjects were assessed one hour following termination of anesthesia. RESULTS Main findings were an increased incidence of foreign body sensation, adherent eyelashes and disturbance elicited by blurred vision in the ointment group as compared to clear hydro-gel (P < 0.001). Bacterial growth was significantly attenuated by the ocular hydro-gel as compared to ointment. DISCUSSION Clear ocular hydro-gel offers improved patient comfort and decreased ocular inflammation as compared to conventional eye ointments. In addition, it decreases bacterial growth. Therefore, the use of clear ocular hydro-gel for perioperative ocular comfort is suggested.

Abstract
BACKGROUND Acute Rhinitis is based on an inflammation of the nasal mucous membrane with nasal discharge and obstruction. Symptomatic treatment includes local application of decongestants as Xylometazoline and epithelia-protective agents as Dexpanthenol. After proving a synergistic effect of Xylometazoline and Dexpanthenol (Nasic) in patients after nasal surgery, this result should be checked in patients with acute non-allergic rhinitis. PATIENTS AND METHODS Randomised verum controlled double-blind parallel-group-comparison of five days treatment with nasal sprays containing the combination of Xylometazolin-Dexpanthenol or Xylometazolin. MAIN OUTCOME MEASURE The assessments of nasal obstruction, rhinorrhea, hyperplasia of nasal concha and redness of the nasal mucous membrane were defined as main-target parameters. RESULTS 152 outpatients diagnosed with non-allergic, acute rhinitis were included in this study. 151 patients completed the study according to protocol. The superiority of the treatment with Xylometazolin-Dexpanthenol could be proven for the main outcome measures in comparison to Xylometazolin clinically relevant and statistically significant. The result was also validated by the secondary endpoints. The clinically proven efficacy is emphasized by the rhinoscopic findings and safety parameters showing a better tolerability of the combination. CONCLUSION Accelerating the wound healing corroborates the superiority of the combination and is due to the epithelia protective effect of Dexpanthenol. These results allow especially under socio-economic points of view the conclusion that shorter treatment time with a diminishing risk of a "rebound effect" will improve compliance.
