Abstract
Herpes simplex virus type 1 (HSV-1) infections are prevalent illnesses that can cause mucocutaneous ulcerative disease, keratitis, and genital herpes. In patients with compromised immune systems, the infection can lead to serious problems, such as encephalitis. Additionally, neonatal infections can cause brain problems and even death. Current first-line antiviral drugs are nucleoside analog inhibitors that target viral polymerase, and resistant strains have emerged. As a result, new drugs with distinct action modes are needed. Recent research indicates that cyclin-dependent kinases (CDKs) are prospective antiviral targets. Thus, CDK inhibitors may be effective antiviral agents against HSV-1 infection. In this study, we examined a panel of CDK inhibitors that target CDKs in the present study. BMS-265246 (BMS), a CDK 1/2 inhibitor, was found to effectively limit HSV-1 multiplication in Vero, HepG2, and Hela cells. A mechanism of action study suggested that BMS inhibits the early stages of viral replication when added early in the viral infection. The suppression of multiple steps in viral replication by BMS was revealed when HSV-1 infected cells were treated at different time periods in the viral life cycle. Our results suggest that BMS is a potent anti-HSV-1 agent and unique in that it may interfere with multiple steps in HSV-1 replication.

Abstract
Herpes labialis remains exceedingly prevalent and is one of the most common human viral infections throughout the world. Recurrent herpes labialis evolves from the initial viral infection by herpes simplex virus type 1 (HSV-1) which subsequently presents with or without symptoms. Reactivation of this virus is triggered by psychosocial factors such as stress, febrile environment, ultraviolet light susceptibility, or specific dietary inadequacy. This virus infection is also characterized by uninterrupted transitions between chronic-latent and acute-recurrent phases, allowing the virus to opportunistically avoid immunity and warrant the transmission to other vulnerable hosts simultaneously. This review comprehensively evaluates the current evidence on epidemiology, pathogenesis, transmission modes, clinical manifestations, and current management options of herpes labialis infections.

Abstract
(1) Background: Tannic acid is a plant-derived polyphenol showing antiviral activity mainly because of an interference with the viral adsorption. In this work, we tested whether the modification of silver nanoparticles with tannic acid (TA-AgNPs) can provide a microbicide with additional adjuvant properties to treat genital herpes infection. (2) Methods: The mouse model of the vaginal herpes simplex virus 2 (HSV-2) infection was used to test immune responses after treatment of the primary infection with TA-AgNPs, and later, after a re-challenge with the virus. (3) Results: The mice treated intravaginally with TA-AgNPs showed better clinical scores and lower virus titers in the vaginal tissues soon after treatment. Following a re-challenge, the vaginal tissues treated with TA-AgNPs showed a significant increase in the percentages of IFN-gamma+ CD8+ T-cells, activated B cells, and plasma cells, while the spleens contained significantly higher percentages of IFN-gamma+ NK cells and effector-memory CD8+ T cells in comparison to NaCl-treated group. TA-AgNPs-treated animals also showed significantly better titers of anti-HSV-2 neutralization antibodies in sera; and (4) Conclusions: Our findings suggest that TA-AgNPs sized 33 nm can be an effective anti-viral microbicide to be applied upon the mucosal tissues with additional adjuvant properties enhancing an anti-HSV-2 immune response following secondary challenge.

Abstract
Bell's palsy is an idiopathic peripheral nerve palsy involving the facial nerve. It accounts for 60 to 75% of all cases of unilateral facial paralysis. The main mechanisms to induce BP remain unclear, but infection, ischemic condition and immunodeficiency may contribute to the development of Bell's palsy. Accumulating evidence has shown several factors can trigger the reactivation of latent HSV including psychological stressors, physical stressors and immunosuppression. Ionization and non-ionization radiations are of importance of physical stressors. Some data have shown radiation can reactivate HSVs. Based on preliminary studies showing radiation reactivation of HSVs, we aimed to hypothesize radiation (in both forms of ionization and non-ionization) may cause Bell's palsy. In the future, the role of radiotherapy, radiofrequency radiation from mobile phones and wireless devices in HSV reactivation and Bell's palsy should be investigated.

Abstract
PURPOSE Infection by Human Herpes Viruses (HHV) types 1-3, are prevalent throughout the world. It is known that radiotherapy can reactivate HHVs, but it is unclear how and to what extent reactivations can interact with or affect radiotherapeutic efficacy, patient outcomes and mortality risk. Herein, we aim to summarize what is known about Herpes Simplex Virus (HSV)-1,2 and Varicella Zoster Virus (VZV) pathophysiology as it relates to tumor biology, radiotherapy, chemo-radiotherapy, diagnosis and management so as to optimize cancer treatment in the setting of active HHV infection. Our secondary aim is to emphasize the need for further research to elucidate the potential adverse effects of active HHV infection in irradiated tumor tissue and to design optimal management strategies to incorporate into cancer management guidelines. MATERIALS AND METHODS The literature regarding herpetic infection, herpetic reactivation, and recurrence occurring during radiotherapy and that regarding treatment guidelines for herpetic infections are reviewed. We aim to provide the oncologist with a reference for the infectious dangers of herpetic reactivation in patients under their care and well established methods for prevention, diagnosis, and treatment of such infections. Pain management is also considered. CONCLUSIONS In the radiotherapeutic setting, serologic assays for HSV-1 and HSV-2 are feasible and can alert the clinician to patients at risk for viral reactivation. RT-PCR is specific in identifying the exact viral culprit and is the preferred diagnostic method to measure interventional efficacy. It can also differentiate between herpetic infection and radionecrosis. The MicroTrak® HSV1/HSV2/VZV staining kit has high sensitivity and specificity in acute lesions, is also the most rapid means to confirm diagnosis. Herpetic reactivation and recurrences during radiotherapy can cause interruptions, cessations, or prolongations of the radiotherapeutic course, thus decreasing the biologically effective dose, to sub-therapeutic levels. Active HHV infection within the treatment volume results in increased tumor radio-resistance and potentially sub-therapeutic care if left untreated. Visceral reactivations may result in fatality and therefore, a high index of suspicion is important to identify these active infections. The fact that such infections may be mistaken for acute and/or late radiation effects, leading to less than optimal treatment decisions, makes knowledge of this problem even more relevant. To minimize the risk of these sequelae, prompt anti-viral therapy is recommended, lasting the course of radiotherapy.

Abstract
Herpes zoster, commonly called shingles, is a disease that results from the reactivation of varicella zoster virus. Local trauma has been reported as a precipitant for reactivation, but this condition is rarely seen localized to a fresh surgical incision. We present the case of a patient who developed shingles overlying the incision site of a recently buried central venous access port, illustrating the need to consider this diagnosis as a unique imposter of localized infection or reaction at sites of recent procedural trauma.

Abstract
PURPOSE Oral mucositis (OM) is a frequent side effect resulting from antineoplastic treatment and is described as an acute alteration characterized by ulcerative lesions, with the presence of a persistent chronic inflammatory infiltrate, erythema, and pain. AIMS The purpose of the study was to evaluate the presence of the herpes simplex virus (HSV-1/2) in patients with squamous cell carcinoma of the head and neck region (SCC) and its influence on the aggravation of oral mucositis after radiotherapy or radio/chemotherapy treatment. METHODS In this prospective cohort study, 91 patients were evaluated with regard to their serological status for IgG before treatment (initial time interval--TI) and for IgM before treatment (T1) and on the 30th day after the first day of radiotherapy application/radiation therapy (final time interval--TF), using immunoenzymatic assay (ELISA), and the results were correlated with the intensity of OM. RESULTS The seroprevalence for IgG was 97.8 %. IgM (TI) was positive in 18.7% and IgM (TF) in 20.9% of patients. All the patients developed some degree of oral mucositis; however, there was statistically significant correlation between positivity for IgM and degree of severity of OM, irrespective of the type of treatment to which the patient was submitted. CONCLUSION The reactivation of HSV-1/2 was shown to be relatively infrequent and there was no correlation between presence of the virus and aggravation of oral mucositis resulting from antineoplastic treatment.

Abstract
BACKGROUND There is a growing body of literature documenting local herpes zoster outbreak following procedures. The mechanism underlying these outbreaks remains elusive. We present a case of zoster following onabotulinumtoxinA (BTX) for migraine and a literature review. METHODS Chart and literature review. CASE A 72-year-old woman with chronic migraine received BTX injections for 3 years without incident. She had a history of thoracic zoster with subsequent post-herpetic neuralgia. In August 2013, 48 hours after receiving BTX injections, she developed a painful rash in the right V1 distribution consistent with herpes zoster ophthalmicus. One week later the rash had resolved without treatment. LITERATURE REVIEW We identified 65 (including 2 from Juel-Jenson) cases of zoster reactivation following minor procedures. These cases tend to be in young patients without specific risk factors. Outbreaks characteristically occur at the level of exposure to local trauma. DISCUSSION Our review suggests that local trauma, regardless of the nature of stimuli, may be sufficient for zoster reactivation. We hypothesize that the stressors in these reported cases exert a local epigenetic influence on viral transcription, allowing for viral reactivation. CONCLUSION Zoster is a potential complication of BTX administration for chronic migraine in adults. Physician awareness can reduce the significant morbidity associated with this disease.

Abstract
Herpes simplex virus infection of the central nervous system is still a significant cause of morbidity and often mortality. Early diagnosis is critical because treatment with the antiviral drug acyclovir dramatically decreases morbidity and mortality in children. The use of polymerase chain reaction techniques is a diagnostic procedure in herpes simplex virus infection, but negative polymerase chain reaction test results of cerebrospinal fluid herpes simplex virus can occur within the first 72 hours of illness, with subsequent test results becoming positive as in this case. Therefore, diffusion-weighted magnetic resonance may play a major role as a first and early diagnostic step.

Abstract
Herpes Simplex Virus Type 1 (HSV-1) is a nuclear replicating enveloped virus, usually acquired through direct contact with infected lesions or body fluids (typically saliva). The prevalence of HSV-1 infection increases progressively from childhood, the seroprevalence being inversely related to socioeconomic background. Primary HSV-1 infections in children are either asymptomatic or following an incubation period of about 1 week gives rise to mucocutaneous vesicular eruptions. Herpetic gingivostomatitis typically affects the tongue, lips, gingival, buccal mucosa and the hard and soft palate. Most primary oro-facial HSV infection is caused by HSV-1, infection by HSV-2 is increasingly common. Recurrent infections, which occur at variable intervals, typically give rise to vesiculo-ulcerative lesions at mucocutaneous junctions particularly the lips (herpes labialis). Recurrent HSV-1 infection within the mouth is uncommon in otherwise healthy patients, although in immunocompromised patients, recurrent infection can be more extensive and/or aggressive. The diagnosis of common herpetic infection can usually be based upon the clinical history and presenting features. Confirmatory laboratory diagnosis is, however, required when patients are, or may be, immunocompromised.

Abstract
Eight of the more than 80 known herpesviruses are human pathogens. Human herpes simplex virus (HSV) is a contagious infection with a large reservoir in the general population. It has a potential for significant complications in the immunocompromised host. In addition, psychological distress caused by the negative stigma associated with genital herpes and visible facial lesions in those experiencing frequent outbreaks renders it a challenging clinical dilemma. This article reviews the epidemiology, pathogenesis, and diagnostic features of HSV infections, providing the clinician with an up-to-date understanding of the available management strategies for mucocutaneous HSV-induced disease.

Abstract
Oral mucositis is a serious complication of cancer therapy and in severely immunosuppressed patients. In immunosuppressed patients, the signs and symptoms of infection often are muted because of limited host response, and accurate diagnosis and appropriate treatment may be difficult. Prevention of mucosal breakdown, suppression of microbial colonization, control of viral reactivation, and effective management of severe xerostomia are all critical steps to reducing the overall morbidity and mortality of oromucosal infections.

Abstract
The literature has been reviewed for evidence of the efficacy of antiviral agents in both the prophylaxis and treatment of recurrent oral herpes simplex virus (HSV) infections and discussed by a panel of experts. Emphasis was given to randomized controlled trials. Management of herpes-associated erythema multiforme and Bell palsy were also considered. The evidence suggests that 5% acyclovir (ACV) in the cream base may reduce the duration of lesions if applied early. Recurrent herpes labialis (RHL) and recurrent intraoral HSV infections can be effectively treated with systemic ACV 400 mg 3 times a day or systemic valacyclovir 500 to 1000 mg twice a day for 3 to 5 days (longer in the immunocompromised). RHL in the immunocompetent can be effectively prevented with (1) sunscreen alone (SPF 15 or above), (2) systemic ACV 400 mg 2 to 3 times a day, or (3) systemic valacyclovir 500 to 2000 mg twice a day. Valacyclovir 500 mg twice a day is also effective in suppressing erythema multiforme triggered by HSV. Further studies are needed to compare treatment efficacy between topical penciclovir, docosanol, and ACV cream for RHL.

Herpes simplex virus type 1 (HSV-1) gives rise to a variety of clinical disorders and is a major cause of morbidity and mortality worldwide. HSV-1 infections are common in oral and perioral area. The aim of the present report was to critically examine the published literature to evaluate the advantages and limitations of therapy of HSV-1 infection in both immunocompetent and immunocompromised patients. Systemic antiviral therapy has been widely accepted as effective for primary herpetic gingivostomatitis. Aciclovir (ACV) 5% cream seems to be the accepted standard topical therapy for herpes labialis, being both effective and well tolerated, although penciclovir 1% cream has been proposed as a potentially useful treatment. Systemic ACV may be effective in reducing the duration of symptoms of recurrent HSV-1 infection, but the optimal timing and dose of the treatment are uncertain. Aciclovir and famciclovir may be of benefit in the acute treatment of severe HSV-1 disease in immunocompromised patients. There is also evidence that prophylactic oral ACV may reduce the frequency and severity of recurrent attack of herpetic infection in immunocompromised patients, but the optimal timing and duration of treatment is uncertain and can vary in different situations.

Abstract
GOAL OF WORK The aim of the study was to investigate the incidence of herpes simplex virus-1 (HSV-1) infection in mucositis during head and neck cancer radiotherapy. PATIENTS AND METHODS Sixty patients with malignant head and neck tumor, eligible to receive radiotherapy, who were referred to the Dental Oncology Unit, entered the study. Sixteen patients (26.6%) received concomitant chemotherapy. Mucositis was recorded weekly. Smears taken from the ulcers of mucositis grade 2, or 3, or 4 were stained with Papanicolaou and alkaline phosphatase/antialkaline phosphatase immunocytochemical method to identify HSV-1. MAIN RESULTS Forty-eight of all 60 patients developed ulcerative mucositis. Smear was available from 29 of 48 patients with ulcerations. HSV-1 infection was identified in 14 of 29 smears available (48.2%). Mucositis healed or was reduced after 1 week of antiviral treatment in 11 of those 14 HSV-1-positive patients; 3 patients responded to 1 g/day of valacyclovir, 7-2 g/day, and 1 patient responded to i.v. acyclovir. Ulcerations recurred after quitting antivirals. Three patients did not respond to 1 g/day of valacyclovir. No HSV-1-negative patient responded to acyclovir (P = 0.000). CONCLUSION HSV-1 was isolated from 14 of 29 available smears taken from 48 patients with ulcerative mucositis. The incidence of HSV-1 infection during radiotherapy was estimated as being 14 of all 48 patients at risk (29.1%). Healing or reduction in the grade of mucositis after antivirals in HSV-1 positive patients, combined with the negative response to antivirals in HSV-1 negative patients, denoted that HSV-1 infection was a component of ulcerative radiation mucositis in those HSV-1-positive patients.

Abstract
PURPOSE Endostatin is a potent antiangiogenesis protein with little or no toxicity that has potential to enhance radiotherapy. The major goal of this study was to evaluate the combination of radiation and endostatin gene therapy in a preclinical lung cancer model. METHODS Plasmid pXLG-mEndo, constructed in our laboratory, includes the mouse endostatin gene cloned into the pWS4 vector. The kinetics of endostatin expression and efficacy of the pXLG-mEndo and radiation ((60)Co gamma-rays) combination was evaluated in the C57BL/6 mouse-Lewis lung carcinoma (LLC) model. The LLC cells were implanted s.c. and pXLG-mEndo was injected intratumorally 12-14 days later without any transfection agent; a dose of 10 Gy radiation was applied approximately 16 h thereafter. Some groups received each modality twice. Endostatin, vascular endothelial growth factor (VEGF), and transforming growth factor-beta1 (TGF-beta1) were quantified in plasma and tumors, and tumor vasculature was examined. RESULTS Endostatin expression within LLC tumors peaked on Day 7 after pXLG-mEndo injection. Addition of radiation to pXLG-mEndo significantly enhanced the level of tumor endostatin compared with plasmid alone (p < 0.05). Tumor growth was significantly delayed in mice receiving pXLG-mEndo plus radiation compared with no treatment (p < 0.005), radiation (p < 0.05), and control plasmid (p < 0.05). The number of LLC tumor vessels was reduced after combined treatment (p < 0.05), and significant treatment-related changes were observed in both VEGF and TGF-beta1. CONCLUSIONS The data demonstrate that delivery of endostatin by pXLG-mEndo as an adjuvant to radiation can significantly enhance the antitumor efficacy of radiotherapy in the LLC mouse tumor model and support further investigation of this unique combination therapy.

Abstract
The pathogenesis underlying the reactivation of latent herpes simplex virus remains undefined. This article presents the case of a 15-year-old male who developed herpes simplex encephalitis, as proven by a positive cerebrospinal fluid polymerase chain reaction and supported by magnetic resonance imaging findings during radiotherapy for pontine glioma. The temporal relation of radiotherapy to the occurrence of herpes simplex encephalitis suggests that cranial irradiation may play a role in the reactivation of latent herpes simplex virus. This finding suggests that herpes simplex encephalitis should be a part of the differential diagnosis of acute neurologic decline in patients undergoing cranial radiotherapy.

Abstract
OBJECTIVE Herpes viruses are characterized by their ability to establish and maintain a latent infection that can reactivate. Only 2 preliminary studies have examined herpes simplex virus (HSV) reactivation in patients receiving head and neck radiotherapy. The role of radiation therapy in the reactivation of a latent virus has not been established. The purpose of the present study was to evaluate the incidence of HSV reactivation in patients receiving radiation treatment for head and neck malignancies. METHODS Twenty patients, 19 of whom were HSV seropositive, undergoing head and neck radiation therapy were assessed weekly before and during radiation therapy, and HSV cultures were completed during cancer treatment. RESULTS Only 3.6% of the cultures were positive for HSV during radiation therapy. HSV was cultured in 4 men receiving a mean of 6,000 cGy to the head and neck area. Recovery from HSV was seen in patients nearing completion of radiation therapy. CONCLUSIONS The results of this study suggest that HSV reactivation is not common during radiation therapy. Therefore, this study does not support prophylaxis of HSV in patients undergoing head and neck irradiation.

Abstract
Periodontal infection may exacerbate during cancer therapy and may result in oral pain and infection, and systemic infection, which may cause morbidity and can lead to mortality in neutropenic cancer patients. Periodontal disease in head and neck cancer patients treated with radiation therapy may lead to acute and chronic complications. The literature was reviewed by a search of Medline of the National Library of Medicine. The search was conducted to identify publications assessing periodontal disease in cancer patients. In addition, a review of papers referenced in the retrieved papers was conducted to identify additional publications for review. Periodontal disease should be assessed and managed prior to medical treatment of cancer for those with oropharyngeal cancer, and for patients in whom neutropenia may develop during treatment. Pretreatment assessment and management, and maintenance of oral hygiene have been shown to be effective in preventing oral and systemic complications during treatment. A complete oral and periodontal examination is appropriate for all patients planned to receive head and neck radiation therapy and those to be treated with medical protocols that are anticipated to result in neutropenia. Oral and periodontal care must continue following cancer therapy, and requires that the health care provider have an understanding of the malignant disease, oral manifestations of the disease, medical management of the disease, and of the oral complications that may develop.

Abstract
Reactivation of latent herpes simplex virus (HSV) in the trigeminal ganglion most commonly gives rise to recurrent herpes labialis and rarely to herpes simplex encephalitis. The mechanisms underlying reactivation of latent trigeminal HSV are complex. Here we report the case history of a 25-year-old woman who developed a fatal, bilateral necrotizing destructive temporal lobe lesion following surgical removal of a cerebellar medulloblastoma and combined radiotherapy and chemotherapy for recurrent tumor. Neuropathologic examination of the brain revealed minimal inflammatory changes, but immunohistochemistry was positive for HSV protein, and HSV deoxyribonucleic acid (DNA) was recovered from formalin-fixed paraffin-embedded brain tissue. The temporal proximity of the surgery, chemotherapy, and radiotherapy to the onset of disease suggests that these factors may have acted as triggers that precipitated conversion of latent HSV to overt HSV.

Abstract
Earlier comparisons of epidemiological and geochemical maps of China disclosed associations between high mortality rates from nasopharyngeal carcinoma (NPC) and low contents of magnesium in the soil. More recent work has shown that high rates of NPC are also associated with high levels of uranium and thorium in the soil. These latest findings are consistent with the earlier ones, since uranium and thorium occur predominantly in acid rocks poor in magnesium. Uranium and thorium are radioactive, and their progeny include radioactive elements such as radium and radon. Whether or not naturally occurring radioactive elements could be risk factors in NPC should, therefore, be further investigated. Direct carcinogenic properties of radon are well known, but in connection with NPC possibilities for reactivation of virus by natural ionizing radiation should also be considered.

Abstract
The oral manifestations of oropharyngeal infection in immunocompromised patients present a particular challenge for both medical and dental professionals because clinical signs and symptoms may be minimal and accurate diagnosis and appropriate treatment may be difficult. Effective control of infection and management of oral symptoms are important and may be achieved by the judicious use of topical and systemic agents and by maintaining good oral hygiene. Prevention of mucosal breakdown, suppression of microbial colonization, control of viral reactivation, and effective management of severe xerostomia are all critical steps to reduce the overall morbidity and mortality of oromucosal infections in the severely immunocompromised patient.
