Abstract
BACKGROUND Xerostomia, or dry mouth, can be a temporary or persistent symptom resulting from various factors, such as medication use, therapeutic radiation, chemotherapy, autoimmune conditions (e.g., Sjögren's syndrome), and hormonal imbalances. Xerostomia often leads to associated mucositis, which significantly impacts patients' quality of life. The nano-bio-fusion (NBF) gingival gel, a gel-type functional toothpaste containing vitamins C, E, propolis, and herbal extracts in a nano-emulsion state, has shown potential in accelerating the healing of oral mucosal lesions. METHODS A total of 127 patients (102 females, 25 males) with persistent xerostomia were treated from 2018 to 2023. Of these, 32 patients were treated exclusively with NBF Gel, while 95 patients received NBF Gel in combination with other medications, such as pilocarpine. The underlying causes of xerostomia included irradiation and chemotherapy (12 patients), medication (40 patients), hormonal imbalance (28 patients), and Sjögren's syndrome (47 patients). NBF Gel was applied 2-3 times daily to the tongue and oral mucosa. Treatment effectiveness was evaluated through physical examinations and a patient-reported scale ranging from 1 (no improvement) to 10 (complete improvement), focusing on the healing of mucosal lesions rather than saliva production. RESULTS Both treatment groups showed significant improvements in the healing of xerostomia-associated mucositis, particularly in severe cases with visible lesions. Patients treated with NBF Gel reported improved symptoms related to mucosal health, while those who received combination therapy also experienced reduced side effects of pilocarpine due to dose reduction. The most substantial improvements were observed in patients with drug-induced and hormonally-caused xerostomia-related mucositis. No adverse side effects from NBF Gel were reported during the study. CONCLUSION NBF gingival gel proved to be beneficial in accelerating the healing of mucositis associated with xerostomia, regardless of the underlying cause, including medication use, radiotherapy, chemotherapy, hormonal imbalances, and Sjögren's syndrome. It presents a promising adjunctive treatment to improve mucosal health and quality of life for patients suffering from xerostomia-associated mucositis.

Abstract
Background: Although low-level laser therapy (LLLT) is a widely used noninvasive treatment because of photobiomodulation effects, its application for xerostomia remained uncertain. Tight junctions (TJs), mainly composed of claudins, occludin, and ZO family members, are crucial structures that determine material transport through paracellular pathway in salivary gland epithelial cells. This work aimed to investigate whether LLLT affected salivary secretion through epithelial TJs. Methods: Transepithelial electrical resistance (TER) measurement and paracellular permeability assay were applied to evaluate paracellular permeability in submandibular gland (SMG)-C6 cells after irradiation with 540 nm green light. Immunofluorescence and western blot were used to detect the expression of TJ proteins. Quantitative phosphoproteomics were performed to explore possible intracellular signals. Results: We found that irradiation with 540 nm green light significantly decreased TER values while increased paracellular transport in SMG-C6 cells. 540 nm green light-induced redistribution of claudin-1, -3, and -4, but not occludin or ZO-1. Moreover, above phenomena were abolished by preincubation with capsazepine, an antagonist of transient receptor potential vanilloid subtype 1. Notably, irradiation with 540 nm green light on the skin covering the whole submandibular gland regions promoted salivary secretion and attenuated lymphocytic infiltration in 21-week-old non-obese diabetic mice (n = 5 per group), a xerostomia animal model for Sjögren's syndrome. Through in-depth bioinformatics analysis and expression verification, ERK1/2 and EphA2 served as potential canonical and noncanonical signals underlying 540 nm green light. Conclusions: Our findings uncovered the novel therapeutic effects of 540 nm green light on xerostomia through regulation on the expression and distribution of TJs.

Abstract
Episil is a bioadhesive barrier-forming liquid gel that can relieve mucositis caused by radiotherapy (RT) and effectively relieve pain. The purpose of this trial is to compare the efficacy and safety of Episil in improving acute radiation dermatitis (ARD) in patients with breast cancer. This study included patients who met the criteria for postoperative RT for breast cancer. The primary end point was the grade of RD during treatment. A total of 102 patients were included in this study. The patients were grouped in a 2:1 ratio using the randomized number table method: 67 patients received Episil combined with conventional skin care (the Episil group), whereas the remaining 35 patients served as the control group and received conventional skin care only (the control group). According to the grading criteria of the Radiation Therapy Oncology Group (RTOG), the skin reaction rate and severity were significantly better in the Episil group than the control group (24.62%, 72.31%, 3.08, 0, 0 vs. 0, 85.71%, 14.29%, 0, 0, 0) across grades 0 to 4 (P < 0.05). The itchiness score exhibited s significant reduction in the Episil group as compared with the control group (P < 0.05). The results of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) showed that the overall health (z = -5.855, P < 0.001) and overall quality of life (z = -6.583, P < 0.001) were better in the Episil group than the control group after RT. Overall, in patients with breast cancer receiving RT, the topical application of Episil may significantly reduce the grading of ARD, alleviate patient symptoms, and improve the patient's overall quality of life.

Abstract
Ferulic acid is a crucial bioactive component of broccoli, wheat, and rice bran and is also an essential natural product that has undergone significant research. Ferulic acid's precise mode of action and effect on system-level protein networks have not been thoroughly investigated. An interactome was built using the STRING database and Cytoscape tools, utilizing 788 key proteins collected from PubMed literature to identify the ferulic acid-governed regulatory action on protein interaction network (PIN). The scale-free biological network of ferulic acid-rewired PIN is highly interconnected. We discovered 15 sub-modules using the MCODE tool for sub-modulization analysis and 153 enriched signaling pathways. Further, functional enrichment of top bottleneck proteins revealed the FoxO signaling pathway involved in enhancing cellular defense against oxidative stress. The selection of the critical regulatory proteins of the ferulic acid-rewired PIN was completed by performing analyses of topological characteristics such as GO term/pathways analysis, degree, bottleneck, molecular docking, and dynamics investigations. The current research derives a precise molecular mechanism for ferulic acid's action on the body. This in-depth in silico model would aid in understanding how ferulic acid origins its antioxidant and scavenging properties in the human body.Communicated by Ramaswamy H. Sarma.

Abstract
Reactive Infectious Mucocutaneous Eruption is an acute mucocutaneous inflammation secondary to an infection with minimal to absent cutaneous features that has recently been linked to the Severe Acute Respiratory Syndrome Coronavirus-19 (SARS-CoV-19 virus). Unfortunately, the relative rarity of case reports of Reactive Infectious Mucocutaneous Eruption in paediatric populations has led to fewer known successful treatment options with the current mainstay being systemic immunosuppression (e.g. corticosteroids, cyclosporine and etanercept). In this case report, we discuss a case of an adolescent patient with (polymerase chain reaction) PCR+ coronavirus disease 2019 infection and an oral eruption without cutaneous symptoms. He was treated successfully using a single dose of dexamethasone and supportive care through amorphous hydrogel (Intrasite gel), thus providing a safe, cheap and effective treatment option in mild coronavirus disease 2019-associated Reactive Infectious Mucocutaneous Eruption in paediatric patients. We also discuss the current findings, diagnostic terms and treatment options of mucosal manifestations of coronavirus disease 2019 in children.

Abstract
Background: Radiodermatitis is a common side effect of breast cancer radiotherapy; however, there is no current consensus regarding an effective standard therapy. Objective: To evaluate the efficacy of topical ectoin versus dexpanthenol in the management of acute radiodermatitis after breast cancer radiotherapy. Methods: Fifty patients randomly used dexpanthenol 5% cream (25 patients), or ectoin 7% cream (25 patients), applied twice daily to the irradiated area during and for 2 weeks after radiotherapy. The study was stratified by the radiotherapy schedule and was double-blind. Radiodermatitis grade, radiation-associated symptoms, and adverse events were assessed weekly during radiotherapy and 2 weeks thereafter. Skin-related quality of life (QOL) scores were measured using the Skindex-16 questionnaire. Results: Both agents were effective in preventing severe radiodermatitis (≥G3). Ectoin had a lower radiodermatitis grade level than dexpanthenol, with a significant difference at week 2 (P = 0.008). Radiation-associated pain (P = 0.003) and itching (P = 0.001) were lower with ectoin than dexpanthenol. Side effects were not significantly different between the 2 treatments (P = 0.107). Ectoin showed less QOL impairment than dexpanthenol. The radiation schedule was an independent predictor for radiodermatitis persistence. Conclusion: Ectoin showed some clinical benefit over dexpanthenol in improving radiation dermatitis and the radiation schedule is a predictor of radiodermatitis persistence.

Abstract
In addition to the anti-diabetic effect of metformin, a growing number of studies have shown that metformin has some exciting properties, such as anti-oxidative capabilities, anticancer, genomic stability, anti-inflammation, and anti-fibrosis, which have potent, that can treat other disorders other than diabetes mellitus. We aimed to describe and review the protective and antidotal efficacy of metformin against biologicals, chemicals, natural, medications, pesticides, and radiation-induced toxicities. A comprehensive search has been performed from Scopus, Web of Science, PubMed, and Google Scholar databases from inception to March 8, 2023. All in vitro, in vivo, and clinical studies were considered. Many studies suggest that metformin affects diseases other than diabetes. It is a radioprotective and chemoprotective drug that also affects viral and bacterial diseases. It can be used against inflammation-related and apoptosis-related abnormalities and against toxins to lower their effects. Besides lowering blood sugar, metformin can attenuate the effects of toxins on body weight, inflammation, apoptosis, necrosis, caspase-3 activation, cell viability and survival rate, reactive oxygen species (ROS), NF-κB, TNF-α, many interleukins, lipid profile, and many enzymes activity such as catalase and superoxide dismutase. It also can reduce the histopathological damages induced by many toxins on the kidneys, liver, and colon. However, clinical trials and human studies are needed before using metformin as a therapeutic agent against other diseases.

Abstract
OBJECTIVES This study sought to evaluate the remineralization of ex vivo human teeth using commercially available artificial saliva, SalivaMAX®, a supersaturated calcium phosphate rinse (SSCPR). METHODS early enamel lesions were artificially induced on ex vivo human teeth by chemical means. The teeth were exposed to the SSCPR for two minutes (experimental) or dH2O (control) four times per day for a total of 35 days. At time points of 0, 2.5, 21, and 35 days, micro-CT was utilized to determine the mineral density profile across the lesion and evaluate lesion depth. The relative percent remineralization was calculated from the initial lesion depth (Time 0) at each evaluation time. Student's t-test was used to compare the extent of remineralization between the SSCPR and control groups for statistical significance at each time. To evaluate the changes in percent remineralization over time, a two-way ANOVA was used. RESULTS At Time 0 and 2.5 days, there was no difference in the percent remineralization between the SSCPR and control groups (p > 0.05). After 21 days, the teeth exposed to the SSCPR remineralized 56.7 ± 3.7%, while the control only remineralized 10.7 ± 11.0% (p < 0.0001). At day 35, the remineralization was 73.7 ± 5.4% and 18.2 ± 10.8% (p < 0.0001) for the SSCPR and control groups, respectively. CONCLUSIONS A marked increase in remineralization occurred with the use of the SSCPR. Notably, the remineralization of the SSCPR occurred deep within the tooth and progressed toward the surface over time.

Abstract
The incidence of head and neck cancers (HNC) is rising worldwide especially with HPV-related oropharynx squamous cell carcinoma. The standard of care for the majority of patients with locally advanced pharyngeal disease is curative-intent radiotherapy (RT) with or without concurrent chemotherapy. RT-related toxicities remain a concern due to the close proximity of critical structures to the tumour, with xerostomia inflicting the most quality-of-life burden. Thus, there is a paradigm shift towards research exploring the use of imaging biomarkers in predicting treatment outcomes. Diffusion-weighted imaging (DWI) is a functional MRI feature of interest, as it quantifies cellular changes through computation of apparent diffusion coefficient (ADC) values. DWI has been used in differentiating HNC lesions from benign tissues, and ADC analyses can be done to evaluate tumour responses to RT. It is also useful in healthy tissues to identify the heterogeneity and physiological changes of salivary glands to better understand the inter-individual differences in xerostomia severity. Additionally, DWI is utilised in irradiated salivary glands to produce ADC changes that correlate to clinical xerostomia. The implementation of DWI into multi-modal imaging can help form prognostic models that identify patients at risk of severe xerostomia, and thus guide timely interventions to mitigate these toxicities.

Abstract
In recent years, evidence has shown the potential therapeutic effects of different natural compounds for the prevention and treatment of radiotherapy-induced mucositis (RIOM). RIOM represents one of the most frequent side effects associated with anti-neoplastic treatments affecting patients' quality of life and treatment response due to radiation therapy discontinuation. The innate radio-protective ability of natural products obtained from plants is in part due to the numerous antioxidants possessed as a part of their normal secondary metabolic processes. However, oxygen presence is a key point for radiation efficacy on cancer cells. The aim of this review is to describe the most recent evidence on radiation-induced injury and the emerging protective role of natural compounds in preventing and treating this specific damage without compromising treatment efficacy.

Abstract
Ginger is a medicinal and valuable culinary plant. Gingerols, as an active constituent in the fresh ginger rhizomes of Zingiber officinale, exhibit several promising pharmacological properties. This comprehensive literature review was performed to assess gingerol's protective and therapeutic efficacy against the various chemical, natural, and radiational stimuli. Another objective of this study was to investigate the mechanism of anti-inflammatory, antioxidant, and antiapoptotic properties of gingerol. It should be noted that the data were gathered from in vivo and in vitro experimental studies. Gingerols can exert their protective activity through different mechanisms and cell signaling pathways. For example, these are mitogen-activated protein kinase (MAPK), nuclear factor-kappa B (NF-kB), Wnt/β-catenin, nuclear factor erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE), transforming growth factor beta1/Smad3 (TGF-β1/Smad3), and extracellular signal-related kinase/cAMP-response element-binding protein (ERK/CREB). We hope that more researchers can benefit from this review to conduct preclinical and clinical studies, treat cancer, inflammation, and attenuate the side effects of drugs and industrial pollutants.

In vivo Study of a Newly Synthesized Chromen-4-one Derivative as an Antitumor Agent against HCC. J Gastrointest Cancer 2021; 53:980-989. [PMID: 34698995 DOI: 10.1007/s12029-021-00724-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/26/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Chromenes are a wide group of natural compounds that can be synthesized chemically. The chromen-4-one nucleus acts as a skeleton for varieties of additional active groups that makes the chromene activity vary between antioxidant and anti-inflammatory agents. In the present study, a newly synthesized chromene compound exhibits different behaviors other than anti-inflammatory and antioxidant activities that it is the first time that a member of chromen-4-one compound can control the cancer progress. Inflammation is the first step in tumor development where the severity grade can potentiate tumor growth and progression. In many tumors, pro-inflammatory genes record high expression level such as tumor necrosis factor (TNF-α) and vascular endothelial growth factors (VEGF). These pro-inflammatory factors act as rate limiting steps in tumor initiation, and controlling its expression acts as an early therapeutic way to control the tumor proliferation. The chromone derivatives have biological activities such as anti-inflammatory and anti-tumor activity. METHODS In the present study, hepatocellular cancer (HCC) induced by diethylnitrosamine (DEN) in rats and then treated with the new chromene derivative and the parameters TNF-α, VEGF, p53, Cyt C, MMP-9, Bcl2, and Bax were measured. RESULTS The treatment strategy Ch compound is to downregulate pro-inflammatory gene expression of early genes as TNF-α as well as VEGF and subsequently control other factors such as p53, Cyt C, and MMP-9. Also, retrieve the balance between Bcl2 and Bax proteins in DEN-induced HCC in rats. CONCLUSION The ability of the new Ch derivative to control the primary initiators of HCC such as TNF-α offers this derivative an anti-tumor activity and encourages further researches to follow and monitor its effect on the molecular level.

[PMID: 33820524 DOI: 10.2174/1871520621666210405093236] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 12/16/2020] [Accepted: 01/15/2021] [Indexed: 11/22/2022]
Abstract
In the treatment of cancer, the use of ionizing radiation is an important modality. However, on the downside, radiation, when used for curative purposes, causes acute dermatitis or radiodermatitis at the site of radiation in most individuals. From a clinical viewpoint, severe dermatitis causes a burning and itching sensation is very painful, and severely affects the quality of life of the individual undergoing treatment. In worse situations, acute radiation dermatitis can cause gaps or breaks in the planned treatment and this can adversely affect the treatment objective and outcome. BACKGROUND In various traditional and folk systems of medicine, plants and plant products have been used since time immemorial for treating various skin ailments. Further, many cosmeceutical creams formulated based on knowledge from ethnomedicinal use are marketed and used to treat various ailments. In the current review, an attempt is made at summarizing the beneficial effects of some plants and plant products in mitigating acute radiation dermatitis in humans undergoing curative radiotherapy. Additionally, the emphasis is also placed on the mechanism/s responsible for the beneficial effects. OBJECTIVE The objective of this review is to summarize the clinical observations on the prevention of radiodermatitis by plant products. In this review, the protective effects of Adlay (Coix lachryma-jobi L.) bran extract, Aloe vera, Calendula officinalis, Cucumis sativus, green tea constituent the epigallocatechin-3-gallate, honey, Achillea millefolium, Matricaria chamomilla, olive oil and some polyherbal creams are addressed by also addressing on the mechanism of action for the beneficial effects. METHODS Two authors' data mined for information in Google Scholar, PubMed, Embase and the Cochrane Library for publications in the field from 1901 up to July 2020. The focus was on acute radiation dermatitis, ionizing radiation, curative radiotherapy, human cancer. The articles were collected and analyzed. RESULTS For the first time, this review addresses the usefulness of natural products like adlay bran, Aloe vera, Calendula officinalis, Cucumis sativus, green tea constituent the epigallocatechin-3-gallate, honey, Achillea millefolium, Matricaria chamomilla, olive oil and some experimentally constituted and commercially available polyherbal creams as skincare agents against the deleterious effects of ionizing radiation on the skin. The protective effects are possibly due to the free radical scavenging, antioxidant, anti-inflammatory, wound healing and skin protective effects. CONCLUSION The authors suggest that these plants have been used since antiquity as medicinal agents and require in-depth investigation with both clinical and preclinical validated models of study. The results of these studies will be extremely useful to cancer patients requiring curative radiotherapy, the dermatology fraternity, agro-based and pharmaceutical sectors at large.

Abstract
Radiation treatments often unfavorably damage neighboring healthy organs and cause a series of radiation sequelae, such as radiation-induced hematopoietic system diseases, radiation-induced gastrointestinal diseases, radiation-induced lung diseases, and radiation-induced skin diseases. Recently, emerging nanomaterials have exhibited good superiority for these radiation-induced disease treatments. Given this background, the rational design principle of nanomaterials, which helps to optimize the therapeutic efficiency, has been an increasing need. Consequently, it is of great significance to perform a systematic summarization of the advances in this field, which can trigger the development of new high-performance nanoradioprotectors with drug efficiency maximization. Herein, this review highlights the advances and perspectives in the rational design of nanomaterials for preventing and treating various common radiation-induced diseases. Furthermore, the sources, clinical symptoms, and pathogenesis/injury mechanisms of these radiation-induced diseases will also be introduced. Furthermore, current challenges and directions for future efforts in this field are also discussed.

Abstract
Background: Radiodermatitis is a frequent side effect of breast cancer radiotherapy (RT). Treating radiation oncologist should know the prevention and treatment of every grade of radiodermatitis. Aims: The aim of this study was to compare the topical corticosteroid and moisturizer usage in breast cancer RT. Materials and Methods: Fifty patients with early-stage breast cancer undergoing breast-conserving surgery referred to our department for adjuvant RT between October 2009 and October 2016 were compared with regard to topical steroid or moisturizer usage. Patients were followed up weekly after the start of treatment. Results: Mean age was 46 years. Twenty-four patients had stage 1 breast cancer and 26 patients had stage 2 disease. KPS (Karnofsky performance score) was 100 for all patients. Five patients (20.8%) had grade 2 and seven (29.1%) patients had grade 1 acute radiodermatitis in the first group. Eleven (42.3%) patients had grade 2 and 12 (46.1%) patients had grade 1 acute radiodermatitis in the second group. Thirteen (54.1%) patients in the first group had no acute radiodermatitis and three (11.5%) patients in the second group had no acute radiodermatitis. No patient in either group experienced grade 3 radiodermatitis. Conclusions: Daily use of topical betamethasone for breast cancer RT improves dermal sparing, reduces acute radiodermatitis, and may be recommended for patients receiving RT to the breast.

Abstract
Fatigue in breast cancer patients undergoing radiotherapy has been studied less comprehensively than fatigue from chemotherapy. The aim of this study was to test the impact of psycho-social factors on the fatigue among breast cancer patients undergoing radiotherapy. This was a cross-sectional correlational study and participants were 210 breast cancer patients currently undergoing radiotherapy in an outpatient setting in Korea. Data collection was carried out from 22 July to 30 September 2019. The results of this study showed that symptom assessment, anxiety and depression, uncertainty, and perceived stress had a direct effect on the fatigue of breast cancer patients receiving radiotherapy, while social support had an indirect effect. These factors explained 67.2% of the fatigue among the participants. This study confirmed that various interventions for symptom assessment, anxiety and depression, uncertainty, and stress reduction need to be developed to reduce fatigue of breast cancer patients receiving radiotherapy. The present results form the basis for developing such interventions.

Abstract
BACKGROUND Treatment for most patients with head and neck cancers includes ionizing radiation with or without chemotherapy. This treatment causes irreversible damage to salivary glands in the irradiation field accompanied by a loss of fluid-secreting acinar cells and a considerable decrease of saliva secretion. There is currently no adequate conventional treatment for this condition. In recent years, we developed an effective culture method to enhance the anti-inflammatory and vasculogenic phenotypes of peripheral blood mononuclear cells (PBMNCs), and such effectively conditioned PBMNC (E-MNC) therapy has shown promising improvements to the function of radiation-injured salivary glands in preclinical studies. However, the safety and effect of E-NMC therapy have yet assessed in human. The objective of this ongoing first-in-man study is to assess the safety, tolerability, and in part the efficacy of E-MNC therapy for treating radiation-induced xerostomia. METHODS/DESIGN This phase 1 first-in-man study is an open-label, single-center, two-step dose escalation study. A total of 6 patients, who had no recurrence of head and neck cancer over 5 years following radiation therapy and suffered from radiation-induced xerostomia, will receive a transplantation of E-NMCs derived from autologous PBMNCs to a submandibular gland. The duration of the intervention will be 1 year. To analyze the recovery of salivary secretion, a gum test will be performed. To analyze the recovery of atrophic salivary glands, computed tomography (CT), and magnetic resonance imaging (MRI) of salivary glands will be conducted. The primary endpoint is the safety of the protocol. The secondary endpoints are the changes from baseline in whole saliva secretion and salivary gland atrophy. DISCUSSION This will be the first clinical study of regenerative therapy using E-MNCs for patients with severe radiation-induced xerostomia. The results of this study are expected to contribute to developing the low-invasive cell-based therapy for radiation-induced xerostomia. TRIAL REGISTRATION This study was registered with the Japan Registry of Clinical Trials (http://jrct.niph.go.jp) as jRCTb070190057.

[PMID: 32037577 DOI: 10.1002/mp.14086] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 02/03/2020] [Accepted: 02/03/2020] [Indexed: 11/11/2022] Open
Abstract
PURPOSE/OBJECTIVE Quantification of surface dose within the first few hundred water equivalent µm is challenging. Nevertheless, it is of large interest for the proton therapy community to study dose effects in the skin. The experimental determination is affected by the detector properties, such as the detector volume and material. The International Commission on Radiation Units and Measurements in its report 39 recommends assessing the skin dose at a depth of 0.07 mm. The aim of this study is the estimation of the absorbed dose at and around a depth of 70 µm. We used various dosimetric approaches in conjunction with proton pencil beam scanning delivery to determine the skin dose in a clinical setting. MATERIAL/METHODS Five different detectors were tested for determining the surface dose in water: EBT3 and HD-V2 GAFCHROMIC™ radiochromic film, LiF:Mg,Ti thermoluminescent dosimeter, IBA PPC05 plane-parallel ionization chamber, and PTW 23391 extrapolation chamber. The irradiation setup consisted of quasi-monoenergetic scanned proton pencil beams with kinetic energies of 100, 150, and 226.7 MeV, respectively. Radiochromic films were placed within a vertical stack and in wedge geometry and were analyzed with FilmQA Pro™ adopting triple channel dosimetry. The extrapolation chamber PTW 23391, which served as a reference in the current work, was used in a conventional ionization chamber setup with a fixed electrode gap of 2 mm. Three Kapton® entrance windows with thicknesses of 25, 50, and 75 µm were employed. Thermoluminescent dosimeters were provided as powder and were pressed onto a sheet of aluminum. Furthermore, the Monte Carlo code TOol for PArticle Simulation (TOPAS) in version 3.1.p2 was used to model an IBA pencil beam scanning nozzle and score dose to water in a water phantom. RESULTS The resulting depth dose curves were normalized to their 100% dose at the reference depth of 3 cm. We obtained the skin doses with the extrapolation chamber and with TOPAS. For the experimental approach this resulted in 79.7 ± 0.3%, 86.0 ± 0.6%, and 87.1 ± 0.1% for the proton energies 100, 150, and 226.7 MeV, respectively. The results for TOPAS were 80.1 ± 0.2% (100 MeV), 87.1 ± 0.5% (150 MeV), and 86.9 ± 0.4% (226.7 MeV), respectively. Based on the experimental results of the skin dose, we provided a clinically relevant surface extrapolation factor for the common measurement methods. This allows the result of the first measurement depth of a detector to be scaled to the dose at the skin depth. Most practical would be the use of the surface extrapolation factor for the PPC05 chamber, due to its direct reading, the wide availability in clinics and the low uncertainties. The calculated factors were 0.986 ± 0.004 for 100 MeV, 0.961 ± 0.008 for 150 MeV, and 0.963 ± 0.003 for 226.7 MeV. CONCLUSIONS In this study, dissimilar experimental approaches were evaluated with respect to measurements at depths close to the surface. The experimental depth dose curves are in good agreement with the simulation with TOPAS Monte Carlo. To the author's knowledge this was the first experimental determination of the skin dose according to the International Commission on Radiation Units and Measurements 39 definition in proton pencil beam scanning.

Abstract
Despite its effectiveness, radiochemotherapy treatment in the head and neck region is accompanied by acute oral complications such as oral mucositis, dysphagia, xerostomia, and dysgeusia. The aim of this study was to analyze and prospectively assess the frequency and evolution of acute oral complications during radiochemotherapy in patients diagnosed with squamous cell carcinoma in the head and neck region. We have analyzed oral complications of 20 patients during 6 weeks of radiochemotherapy treatment for squamous cell carcinoma. Oral mucositis was evaluated according to the World Health Organization criteria, dysphagia, and dysgeusia according to the National Cancer Institute Common Toxicity Criteria, and xerostomia according to parameters set by the Seminars in Radiation Oncology. Mucositis was first observed in the second week and all patients presented some degree of mucositis in the fourth week of radiotherapy. Xerostomia and dysphagia were initially reported already in the first week of radiotherapy. All patients presented xerostomia in the fourth week; however, dysphagia was observed in all patients, only in the sixth week. Dysgeusia was first observed in the second week, becoming more severe in the third week. Acute oral complications can be observed throughout the treatment, but the third week of radiotherapy seems to represent a critical week, regardless of the grade of the complication. The sixth week presents the worst grades of these complications. Knowledge about the natural course of oral complications during radiotherapy is important to develop better strategies for treatment and improve the patients' quality of life.

Abstract
OBJECTIVE The present study aimed to evaluate the effectiveness of Nigella sativa L. (N. sativa) extract on preventing the incidence of acute radiation dermatitis (ARD) in breast cancer patients. METHODS Sixty-two breast cancer patients undergoing radiotherapy (RT) were randomly assigned to receiveN. sativa 5% gel or placebo. Patients were instructed to apply the medications twice daily during RT period. The severity of ARD, the incidence of moist desquamation, worst experienced pain, and skin-related quality of life (SRQOL) scores were assessed weekly during RT. RESULTS Patients who were treated with the N. sativa gel developed ARD significantly less frequently compared to those who used the placebo (p < 0.05 for all weeks except week 2, p = 0.36). The incidence time of grade 2 and 3 of Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer (RTOG/EORTC) toxicity was prolonged significantly with N. sativa gel as compared to placebo (35 vs. 29 days, p = 0.00 and 42 vs. 40 days, p = 0.01, respectively). Furthermore, the occurrence of moist desquamation was delayed in the N. sativa gel group compared with the placebo group (37 vs. 33 days, p = 0.01). The mean score of the worst pain that patients experienced in the placebo group was significantly higher than that of the N. sativa gel group at week 3 (2.5 ± 0.5 vs. 1.2 ± 0.3, p < 0.05). Nonetheless, the application of N. sativa gel had no significant effect on the SRQOL of patients at any week. CONCLUSION N. sativa extract significantly decreases the severity of ARD and delays the onset of moist desquamation in breast cancer patients.

Abstract
Introduction: Xerostomia is a frequent complication after curative intended radiotherapy (RT) for head and neck squamous cell carcinoma (HNSCC). Assessment of xerostomia is commonly done by the physician. The aim of this study is to investigate the relation between patient and physician-rated xerostomia and to predict the degree of xerostomia from patients with self-reported xerostomia based on delivered doses to the oral cavity, parotid, and submandibular glands. Material and methods: During a 2-year period, consecutive HNSCC patients attending the follow-up clinic were included. All included patients had self-reported xerostomia, and completed the disease-specific EORTC QLQ-H&N35 questionnaire. The physician assessed the degree of xerostomia with the DAHANCA toxicity scale and was blinded for the EORTC score. Oral cavity, parotid, and submandibular glands (OAR) were delineated on the planning CT according to international guidelines. DVH were extracted from treatment plans. Logistic regression tested the relation between mean doses, patient characteristics, and xerostomia scores. Differences between DVH values and scoring of xerostomia were analyzed with a Kruskal-Wallis test. The relation between xerostomia and dose distributions was further investigated using principal component analysis (PCA). Results: In total, 109 patients were included in the study. A weak correlation was seen between patient and physician-rated toxicity (p = .001), however, in general patients reported more toxicity than physicians. For EORTC score ≥2, the multi-variable analysis was significant for doses to the oral cavity, tobacco status and use of xerogenic medication. Neither the DVH analysis nor the PCA found any clear distinction between xerostomia scores for EORTC or DAHANCA and investigated OARs. Conclusion: Patients tended to report higher scores of xerostomia than the physician. PCA indicated a complex relation between doses to the OAR and xerostomia scores, showing e.g., that reducing doses in one organ was on the expense of increased dose to another organ.

Abstract
The chronic sensation of a dry mouth is a disease condition called xerostomia and affects a large part of the population. Xerostomia is associated with decreased secretion, or more often, qualitative changes in saliva proteins and immunoglobulin concentrations that develop as a result of salivary gland dysfunction. Several reasons causing dry mouth were described, and usually, they include taking medications, diseases or radiotherapy. In some situations, when it is difficult to use salivary stimulants or salivary gland damage is irreversible, the only option might seem to be saliva substitutes. The paper presents the most important aspects considering saliva preparations. The rheological and lubricating properties and the reconstruction of the complex saliva structure has been the main purpose of research. The biological properties of saliva preparations were also widely discussed. As part of the work, the antimicrobial effect of three commercial saliva preparations was tested. Finally, inadequate antimicrobial properties against the strains isolated from the oral cavity were demonstrated. The development of salivary substitutes, in particular, the improvement of antimicrobial properties, can be achieved using nanotechnology, including drug delivery systems containing nanocarriers.

Abstract
Purpose: To investigate the prevention effect of low-temperature atomization inhalation for radiation induced oral mucositis (OM) in patients with head and neck cancer (HNC) undergoing radiotherapy. Patients and methods: A total of 68 patients with HNC (including nasopharyngeal cancer) undergoing radiotherapy were divided into an intervention group (33 cases) and a control group (35 cases). During radiotherapy, the intervention group received low-temperature (between 4°C and 8°C) atomization inhalation; while the control group received normal temperature (between 18°C and 24°C) atomization inhalation. Atomization inhalation was performed twice a day, 20 minutes per time, using distilled water. The incidence and severity of OM was evaluated every week during radiotherapy. The comparation was made between the two groups. Results: The two groups were comparable among age, sex, Eastern Cooperative Oncology group (ECOG) score, body mass index (BMI) before radiotherapy, BMI loss during radiotherapy, original tumor site, pathological type, TNM stage, and mean oral cavity irradiated dose. There was a significant difference in the incidence of OM between the two groups (P<0.05). There were fewer patients with severe OM in the intervention group compared to the control group (P<0.05). The onset time of OM in the intervention group was delayed by about 4 days compared to that in the control group (P<0.05). Low-temperature atomization inhalation helped to avoid radiotherapy interruption in the intervention group. No patient in the intervention group suffered any adverse reaction for low-temperature atomization inhalation treatment. Conclusions: Low-temperature atomization inhalation can reduce the incidence and severity of OM, and slow down the progression process of it. It can be used as a new prevention method during radiotherapy, and should be promoted in clinical practice.

Abstract
Oral mucositis (OM) is a common and dose-limiting side effect of cancer treatment, including 5-fluorouracil (5-FU) and radiotherapy. The efficacy of the therapeutic measures to prevent OM is limited and disease prevention is not fully observable. Amifostine is a cytoprotective agent with a described anti-inflammatory potential. It is clinically used to reduce radiotherapy and chemotherapy-associated xerostomia. This study investigated the protective effect of amifostine on an experimental model of OM. Hamsters were divided into six groups: saline control group (5 mL/kg), mechanical trauma (scratches) of the right cheek pouch; 5-FU (60 and 40 mg/kg, ip, respectively, administered on days 1 and 2); amifostine (12.5, 25, or 50 mg/kg) + 5-FU + scratches. Salivation rate was assessed and the animals were euthanized on day 10 for the analysis of macroscopic and microscopic injury by scores. Tissue samples were harvested for the measurement of neutrophil infiltration and detection of inflammatory markers by ELISA and immunohistochemistry. 5-FU induced pronounced hyposalivation, which was prevented by amifostine (P<0.05). In addition, 5-FU injection caused pronounced tissue injury accompanied by increased neutrophil accumulation, tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β) tissue levels, and positive immunostaining for TNF-α, IL-1β, and inducible nitric oxide synthase (iNOS). Interestingly, amifostine prevented the inflammatory reaction and consequently improved macroscopic and microscopic damage (P<0.05 vs 5-FU group). Amifostine reduced inflammation and protected against 5-FU-associated oral mucositis and hyposalivation.

Abstract
Radiotherapy is considered as a primary modality for cancer treatment which accompanied by several side effects. Protection of normal tissues from radiation effects is one of the most significant concerns for researchers. Although many compounds acting as radio protectors, only two compounds were licensed clinically. Cyclooxygenase-2 (COX-2), as an inflammatory mediator is associated with ROS production with a NF-κB gene up regulation dependent manner in normal tissues. To that extend, his study was designed to target COX-2 and NF-κB by a newly synthesized benzopyran-4-one or chromone derivative; (2E)-2-((4-oxo-4H-chromen-3-yl) methylene amino-4- nitrobenzoic acid (Ch). Exposure of mice to IRR significantly induced intestinal inflammation via overexpression of COX-2 and NF-κB which is accompanied by an increase in the levels of MDA and iNOS in tissue homogenate and in the production of TNF-α and IL-6 as inflammatory signs. Moreover, the apoptotic effect of IRR was manifested by obvious elevation in caspase-3. Interapretonial injection of Ch significantly controls the inflammatory response by blocking the COX-2 and decrease the expression NF-κB which subsequently decreases other inflammatory parameters. Thus Ch compound might be a promising nonsteroidal anti-inflammatory drug (NSAID) against radiation-induced inflammation with a specific mode of COX-2 inhibition. Further researches are needed to elucidate its molecular mechanism and its combination with radiotherapy as a protector.

Abstract
BACKGROUND Honey is a natural product made from the nectar of flowers by honey bees and has over 200 compounds in it, including sugars, water, organic acids, minerals and polyphenols - the exact structure and composition of honey often determined by which plant source(s) the honey bee took the nectar from. Honey has been used in diets and medicines for thousands of years; however, this review, for the first time, aims to look at its place in modern medicine concerning oral health. HIGHLIGHT The present review for the first time attempted to address the protective effect of honey in the oral care. CONCLUSION For the first time this review addresses the usefulness of honey against Streptococcus mutans infections, dental plaque and caries, gingivitis and halitosis. Honey was also useful in preventing side effects associated with treatment of cancers of the head and neck, namely, radiation induced mucositis, xerostomia and poor wound healing. This is well supported by evidence in literature and was examined in this review.

Abstract
Unmitigated UV radiation (UVR) induces skin photoaging and multiple forms of cutaneous carcinoma by complex pathways that include those mediated by UV-induced reactive oxygen species (ROS). Upon UVR exposure, a cascade of events is induced that overwhelms the skin’s natural antioxidant defenses and results in DNA damage, intracellular lipid and protein peroxidation, and the dysregulation of pathways that modulate inflammatory and apoptotic responses. To this end, natural products with potent antioxidant properties have been developed to prevent, mitigate, or reverse this damage with varying degrees of success. Mitochondria are particularly susceptible to ROS and subsequent DNA damage as they are a major intracellular source of oxidants. Therefore, the development of mitochondrially targeted agents to mitigate mitochondrial oxidative stress and resulting DNA damage is a logical approach to prevent and treat UV-induced skin damage. We summarize evidence that some existing natural products may reduce mitochondrial oxidative stress and support for synthetically generated mitochondrial targeted cyclic nitroxides as potential alternatives for the prevention and mitigation of UVR-induced skin damage.

Abstract
Background: Xerostomia is a very relevant and frequent complication of radiotherapy, causing the irradiated oral mucosa to be affected by bacterial, fungal and viral infections. Objective: The objective of this study was to evaluate a possible relationship between oral shedding of human herpesviruses and xerostomia in patients with squamous cell carcinoma of head and neck submitted to radio/chemotherapy. Methods: In this study, oral rinse samples were collected weekly from 20 patients during radiotherapy. The samples were submitted to PCR and enzymatic digestion for detection of human herpesviruses. Xerostomia was evaluated according to the Seminars in Radiation Oncology criteria. Results: There was a higher frequency of grade 1 xerostomia (51.4%), observed first in the 1st week of radiotherapy. In the 4th week of radiotherapy, all patients presented some degree of xerostomia. Analysis of herpesviruses showed oral shedding of EBV, HHV-6 and HHV-7 in all weeks. Considering all the periods, the highest frequency was in patients with EBV excretion (55.0%), which was significantly higher than that of other viruses. Conclusion: We observed that oral shedding of herpesviruses was not affected by xerostomia as there was a progression in their excretion, even with the evolution of xerostomia. This suggested that there is a local replication in the oral cavity that is not completely dependent of salivary excretion.

Abstract
AIM To offer a practice insight for the management of chemoradiation toxic mucositis. METHOD Review chemoradiation toxic mucositis, its pathobiology and breadth of symptom presentation. Review mucositis guidelines and guideline-supported anti-mucositis therapies. Offer guidance on guidelines and an abbreviated review of high potency cross-linked sucralfate for management of chemoradiation toxic mucositis. RESULT There are six major mucositis guidelines but only one that is current and regularly updated. Guidelines from the Multinational Association Supportive Cancer Care suggest 14 interventions gleaned from controlled trials, 12 of which are off-label uses of therapies that offer statistically significant but incrementally beneficial outcomes. Several evidence-based limitations of guidelines are discussed. Data on high potency polymerized cross-linked sucralfate confirming complete prevention and rapid (2-3 days) elimination, sustained throughout cancer treatment is verified as high quality evidence in accordance to standards adopted by Agency for Healthcare Research and Quality. A 96-97% reduction in mucositis duration qualifies as a positive Glasziou treatment effect, which is discussed as an additional measure of evidence-based medicine. CONCLUSION Statistically significant but fractional treatment effects of guideline-supported interventions are not likely to substantially alter the course of mucositis when it occurs nor completely prevent its onset. Complete prevention and rapid sustained elimination should be the goal, therefore high potency polymerized cross-linked sucralfate may be useful. Where guidelines fail, institution-based protocols led by oncology pharmacists could succeed. In an effort to eliminate toxic mucositis, enhance compliance to chemoradiation regimens, and improve survival, such protocols for practice may verify pharmacoeconomic benefits, if any, in using high potency polymerized cross-linked sucralfate to manage toxic mucositis.

An Aloe Vera-Based Cosmeceutical Cream Delays and Mitigates Ionizing Radiation-Induced Dermatitis in Head and Neck Cancer Patients Undergoing Curative Radiotherapy: A Clinical Study. MEDICINES 2017; 4:medicines4030044. [PMID: 28930258 PMCID: PMC5622379 DOI: 10.3390/medicines4030044] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2017] [Revised: 06/14/2017] [Accepted: 06/19/2017] [Indexed: 11/16/2022]
Abstract
Background: This study was planned to evaluate the efficacy of topical application of an Aloe vera-based cream (AVC) for the prevention of ionizing radiation (X ray)-induced dermatitis in head and neck cancer patients requiring therapeutic radiation treatment (>62 Gy). Methods: From July 2012 to December 2012, a total of 60 head and neck cancer patients requiring curative radiotherapy (RT) of more than 66 Gy were prospectively enrolled and treated with AVC or a comparator Johnson’s Baby Oil (JBO). Acute skin reaction was monitored and classified according to the Radiation Therapy Oncology Group (RTOG) four-point rating scale on a weekly basis. Results: The results indicate that there was a statistically significant delay in the incidence (p = 0.04) of dermatitis at week three in the AVC application group. Application of AVC reduced the incidence of Grade 1, 2, and 3 dermatitis at subsequent time points, while Grade 4 dermatitis was not seen in either cohort. The other most important observation was that the continued application of AVC two weeks after the completion of RT was effective in reducing the average grade of dermatitis and was statistically significant (p < 0.02). Conclusions: Prophylactic use of an AVC-based cream is thus effective in delaying radiation dermatitis in head and neck cancer.

Abstract
Background: The primary objective of this study was to ascertain the benefit of Vicco turmeric Ayurvedic cream (VTC; Vicco Laboratories, Mumbai, India) sandalwood oil and turmeric-based cream in preventing radiodermatitis in women undergoing curative radiotherapy for their breast cancer. Methods and Materials: The study was an investigator-blinded randomized study with Johnsons Baby Oil (JBO; Johnson & Johnson Ltd., Baddi, India) as a comparator, administered daily from the start of radiation therapy for 5 weeks in women receiving breast radiation therapy, 50 Gy in 2 Gy fractions daily for 5 weeks. The endpoints were to ascertain the delay in the appearance and the degree of severity of dermatitis throughout the study period in accordance to the Therapy Oncology Group (RTOG) score. Results: The results indicated that the topical application of VTC delayed and mitigated the radiodermatitis. When compared to the Johnson’s Baby Oil, a significant decrease (p = 0.025) in the incidence of grade 1 was seen at week two, and also in grade 2 and 3 at week 3 (p = 0.003) and week 4 (p = 0.02), respectively, in the VTC cohort. A concomitant decrease in the average severity was also observed at week 2 (p = 0.02), week 3 (p = 0.05) and week 4 (p = 0.03). Conclusions: The results indicate that VTC cream significantly reduces radiation dermatitis when applied to the breast during and after radiation therapy. The result of this study indicates the beneficial effects. Double blind randomized control studies are required to further confirm the beneficial effects of VTC in mitigating radiodermatitis is people undergoing radiation treatment for their cancer.

Abstract
The primary goal of radiotherapy in oncology is to enhance the efficacy of tumor cell death while decreasing damage to surrounding normal cells. Positive therapeutic outcomes may be accomplished by improved targeting, precisely targeting tumor cells or protecting normal cells against radiation-induced damage. The potential for antioxidants to decrease normal tissue damage induced by radiation has been investigated in animal models for a number of decades. In attempts for radioprotection, certain synthetic chemicals are suggested as antioxidants and normal tissue protectors against radiation-induced damage, but they have exhibited limitations in pharmacological application due to undesirable effects and high toxicities at clinical doses. The present review focuses on the radioprotective efficacy of traditional oriental medicines with the advantage of low toxicity at pharmacological doses and how such treatments may influence various harmful effects induced by radiation in vitro and in vivo. In addition, medicinal plants and their active constituents with biological activities that may be associated with alleviation of radiation-induced damage through antioxidant, anti-inflammatory, wound healing and immunostimulatory properties are discussed.

Abstract
AIMS AND OBJECTIVES To review literature associated with external beam radiotherapy and skin damage. A focus of the literature search is to highlight and discuss the myriad of skin assessment tools that are available to the clinician when assessing skin injury in patients receiving external beam radiation therapy. BACKGROUND It is apparent that despite considerable work being progressed in the development of individualised skin assessment tools, uptake and use is poor. These tools are designed to assist the clinician in the evaluation of damaged skin and predict the radiation wound development pathway. DESIGN An integrated review can be used to address a mature or new and emerging topic through a systematic methodology, which is either theoretical or empirical, gained from research, practice or policy initiatives (Whittemore & Knafl, Journal of Advanced Nursing, 52, 2005, 546). This review is particularly concerned with the employment of skin assessment tools by clinicians in patients with radiation damaged skin. Using the search terms synonyms for radiation, skin and epidermal damage, PubMed/MEDLINE, Medical Complete and Web of Science databases were searched. Consulting professional peers was employed as part of the inclusion and exclusion process. CONCLUSION There is a high level of unpredictability about which patient will have an uncomplicated course of external beam radiotherapy. Variables may include, but are not limited to, an acute reaction, a delayed reaction resulting in actual skin damage or no visible skin disturbance. The skin assessment tools that are readily available are not regularly referenced in clinical practice when attempting to manage the many side effects of radiation therapy. Skin assessment tools require ongoing clinical validation, so they can be used to guide practitioners to undertake further assessment of skin integrity. RELEVANCE TO CLINICAL PRACTICE The current body of knowledge suggests clinicians caring for patients receiving therapeutic radiotherapy should consider integrating a recognised patient assessment skin framework into their daily routine. Such validated tools may add value to postradiotherapy patient care by providing a consistency of management and accordingly refining best practice.

Abstract
PURPOSE Radiation-induced xerostomia is one of the most common side effects that head and neck cancer patients experience during and after treatment. Despite the various methods for the prevention and treatment of radiation-induced xerostomia, it remains highly prevalent among patients treated for head and neck cancers negatively influencing their lives. The purpose of this study was to evaluate the effectiveness of thyme honey as a means for managing radiation-induced xerostomia. METHOD This was a parallel randomised controlled trial with two equal arms, the experimental arm (thyme honey) and the control arm (saline). 72 head and neck cancer patients receiving radiotherapy or/and chemotherapy or/and surgery were recruited in a specialised cancer centre. Patients in both arms followed the same administration protocol with thyme honey and saline respectively. Identical assessments at baseline, 1 month and 6 months following completion of the intervention were performed in both arms including the National Cancer Institute (NCI) xerostomia scale and the Xerostomia Questionnaire (XQ) additionally to weekly oral clinical assessments. The ClinicalTrials.gov Identifier for this study is NCT01465308. RESULTS Linear Mixed Models revealed the statistically significant effect of the intervention on xerostomia (F = 8.474 p < 0.001) and overall quality of life (F = 13.158 p < 0.001). Moreover, Generalised Estimating Equations revealed a statistically significant effect on strong and unbearable pain (F = 10.524 p < 0.001) and dysphagia (F = 4.525 p = 0.033). CONCLUSION The study has demonstrated the safety and efficacy findings of Thyme honey in head and neck cancer patients for the management of treatment induced xerostomia.

Abstract
Radiodermatitis (radiation dermatitis, radiation-induced skin reactions, or radiation injury) is a significant side effect of ionizing radiation delivered to the skin during cancer treatment as well as a result of nuclear attacks and disasters, such as that which occurred in Fukushima in 2011. More specifically, 95 % of cancer patients receiving radiation therapy will develop some form of radiodermatitis, including erythema, dry desquamation, and moist desquamation. These radiation skin reactions result in a myriad of complications, including delays in treatment, diminished aesthetic appeal, and reduced quality of life. Recent technological advancements and novel treatment regimens have only been successful in partly ameliorating these adverse side effects. This article examines the current knowledge surrounding the pathogenesis, clinical manifestations, differential diagnoses, prevention, and management of radiodermatitis. Future research should examine therapies that incorporate the current understanding of the pathophysiology of radiodermatitis while measuring effectiveness using objective and universal outcome measures.

Abstract
Radiation therapy (RT) evolved to be a primary treatment modality for cancer patients. Unfortunately, the cure or relief of symptoms is still accompanied by radiation-induced side effects with severe acute and late pathophysiological consequences. Inhibitors of cyclooxygenase-2 (COX-2) are potentially useful in this regard because radioprotection of normal tissue and/or radiosensitizing effects on tumor tissue have been described for several compounds of this structurally diverse class. This review aims to substantiate the hypothesis that antioxidant COX-2 inhibitors are promising radioprotectants because of intercepting radiation-induced oxidative stress and inflammation in normal tissue, especially the vascular system. For this, literature reporting on COX inhibitors exerting radioprotective and/or radiosensitizing action as well as on antioxidant COX inhibitors will be reviewed comprehensively with the aim to find cross-points of both and, by that, stimulate further research in the field of radioprotective agents.

Abstract
Objectives: Amifostine is a drug which can eliminate free oxygen radicals that appear in the body after radiation or chemotherapeutic agent exposure. It is used to decrease the renal toxicity of cisplatin. The aim of this study was to determine the role of amifostine in warm ischemia kidney model for prevention of ischemia/reperfusion injury and also to find out the mechanism for prevention from ischemia/reperfusion injury if such an effect does exist. Materials and Methods: Adult female rats (n = 40) that used in our study were divided into three groups. Group 1: Control (n = 8), group 2: Ischemia-control (n = 16), group 3: Amifostine treated (n = 16). The effect of amifostine on ischemia/reperfusion injury investigated in rat kidneys. Results: At the 7th day, blood urea nitrogen level was statistically significantly higher in ischemia-control group than all groups (P = 0.001) and mean serum creatinine levels were found to be the highest in ischemia-control group (P = 0.091). Mean malondialdehyde levels in left kidneys removed on the 7th day were not significantly different (P = 0.105) at all three groups. Between ischemia-control group and amifostine group, there was a significant difference in reduced glutathione (GSH) levels (P = 0.001). In amifostine group, grade 4 necrosis was not detected neither on 7th day nor day 0. Conclusion: Amifostine could decrease the degree and severity of necrosis after reperfusion. Amifostine could not prevent membrane lipid peroxidation caused by superoxide anion radicals in kidney but they could protect tissues from the harmful effects of ischemia/reperfusion injury by increasing the level of reduced GSH which is a well-known oxygen radical eliminator.

Abstract
BACKGROUND The irradiation of head and neck cancer (HNC) often causes damage to the salivary glands. The resulting salivary gland hypofunction and xerostomia seriously reduce the patient's quality of life. PURPOSE To analyze the literature of actual management strategies for radiation-induced hypofunction and xerostomia in HNC patients. METHODS MEDLINE/PubMed and the Cochrane Library databases were electronically evaluated for articles published from January 1, 1970, to June 30, 2013. Two reviewers independently screened and included papers according to the predefined selection criteria. RESULTS Sixty-one articles met the inclusion criteria. The systematic review of the literature suggests that the most suitable methods for managing the clinical and pathophysiological consequences of HNC radiotherapy might be the pharmacological approach, for example, through the use of cholinergic agonists when residual secretory capacity is still present, and the use of salivary substitutes. In addition, a modified diet and the patient's motivation to enhance oral hygiene can lead to a significant improvement. CONCLUSION Radiation-induced xerostomia could be considered a multifactorial disease. It could depend on the type of cancer treatment and the cumulative radiation dose to the gland tissue. A preventive approach and the correct treatment of the particular radiotherapeutic patient can help to improve the condition of xerostomia.

Lycium barbarum berries, also named wolfberry, Fructus lycii, and Goji berries, have been used in the People’s Republic of China and other Asian countries for more than 2,000 years as a traditional medicinal herb and food supplement. L. barbarum polysaccharides (LBPs) are the primary active components of L. barbarum berries and have been reported to possess a wide array of pharmacological activities. Herein, we update our knowledge on the main pharmacological activities and possible molecular targets of LBPs. Several clinical studies in healthy subjects show that consumption of wolfberry juice improves general wellbeing and immune functions. LBPs are reported to have antioxidative and antiaging properties in different models. LBPs show antitumor activities against various types of cancer cells and inhibit tumor growth in nude mice through induction of apoptosis and cell cycle arrest. LBPs may potentiate the efficacy of lymphokine activated killer/interleukin-2 combination therapy in cancer patients. LBPs exhibit significant hypoglycemic effects and insulin-sensitizing activity by increasing glucose metabolism and insulin secretion and promoting pancreatic β-cell proliferation. They protect retinal ganglion cells in experimental models of glaucoma. LBPs protect the liver from injuries due to exposure to toxic chemicals or other insults. They also show potent immunoenhancing activities in vitro and in vivo. Furthermore, LBPs protect against neuronal injury and loss induced by β-amyloid peptide, glutamate excitotoxicity, ischemic/reperfusion, and other neurotoxic insults. LBPs ameliorate the symptoms of mice with Alzheimer’s disease and enhance neurogenesis in the hippocampus and subventricular zone, improving learning and memory abilities. They reduce irradiation- or chemotherapy-induced organ toxicities. LBPs are beneficial to male reproduction by increasing the quality, quantity, and motility of sperm, improving sexual performance, and protecting the testis against toxic insults. Moreover, LBPs exhibit hypolipidemic, cardioprotective, antiviral, and antiinflammatory activities. There is increasing evidence from preclinical and clinical studies supporting the therapeutic and health-promoting effects of LBPs, but further mechanistic and clinical studies are warranted to establish the dose–response relationships and safety profiles of LBPs.
