Abstract
The purpose of this descriptive study was to examine gender differences in the disease experience of persons who have genital herpes. Participants were 60 volunteers (34 females, 26 males) with recurrent genital herpes. Their average age was 31.7 years and the average length of time since diagnosis was 5.3 years. They completed questionnaires that included items about disease characteristics, disease stressors, and disease impact. The majority of reported stressors related to the consequences of the disease. A wide diversity of stressors were described, and results gave evidence of gender similarities in the disease experience. Exceptions were that women reported experiencing more worry with regard to negative effects on future and present health, disruption of daily activity, and disease symptoms. Men reported that recurrences last longer. Both disease symptoms and the presence of an intimate relationship were related to the perceived disease impact. Implications for sensitive interventions are discussed.

Abstract
HSV-1 continues to be the leading cause of infectious corneal blindness. Clinical trials for vaccines against genital HSV infection have been ongoing for more than three decades. Despite this, no approved vaccine exists, and no formal clinical trials have evaluated the impact of HSV vaccines on eye health. We review here the current state of development for an efficacious HSV-1 vaccine and call for involvement of ophthalmologists and vision researchers.

Abstract
Herpes simplex virus (HSV) is associated with a variety of ocular diseases, including epithelial and stromal keratitis. HSV can cause stromal opacification and is believed to be the leading cause of infectious blindness in the developed world. An improved understanding of the global burden of HSV keratitis, including the incidence of severe vision loss, could have a significant effect on prevention and treatment and place it in perspective among causes of corneal ulceration. We found that the global incidence of HSV keratitis is roughly 1.5 million, including 40,000 new cases of severe monocular visual impairment or blindness each year. We also discuss relevant epidemiologic issues regarding HSV epithelial and stromal disease.

Abstract
Infection prevention in dentistry is an important topic that has gained more interest in recent years and guidelines for the prevention of cross-transmission are common practice in many countries. However, little is known about the real risks of cross-transmission, specifically in the dental healthcare setting. This paper evaluated the literature to determine the risk of cross-transmission and infection of viruses and bacteria that are of particular relevance in the dental practice environment. Facts from the literature on HSV, VZV, HIV, Hepatitis B, C and D viruses, Mycobacterium spp., Pseudomonas spp., Legionella spp. and multi-resistant bacteria are presented. There is evidence that Hepatitis B virus is a real threat for cross-infection in dentistry. Data for the transmission of, and infection with, other viruses or bacteria in dental practice are scarce. However, a number of cases are probably not acknowledged by patients, healthcare workers and authorities. Furthermore, cross-transmission in dentistry is under-reported in the literature. For the above reasons, the real risks of cross-transmission are likely to be higher. There is therefore a need for prospective longitudinal research in this area, to determine the real risks of cross-infection in dentistry. This will assist the adoption of effective hygiene procedures in dental practice.

Abstract
Herpes simplex virus (HSV) is one of the most common viral infections of the human being. Although most of the seropositive persons do not manifest symptoms, infected individuals may present recurrent infections, characterized by cold sores. HSV-1 infection can result in potentially harmful complications in some patients, especially in those with compromised immunity. We report a clinical case of a patient with severe oral HSV-1 infection in the lower lip. The treatment of the lesions with the association of high-intensity (erbium-doped yttrium aluminum garnet, 2.94 mum, 80 mJ/pulse, 2-4 Hz) and low-intensity (indium gallium aluminum phosphide, 660 nm, 3.8 J/cm(2), 10 mW) lasers has not been reported in the literature. During treatment, no systemic or topical medication was used. Pain sensitivity was completely gone after the first irradiation with the low-intensity laser. During the healing process, lesions were traumatized twice, on the days 4 and 7. Even though the lesions were completely healed within 10 days.

Abstract
The frequent oral shedding of herpes simplex virus type 1 (HSV-1) in the absence of clinical disease suggests that symptomatic HSV-1 recurrences may be inhibited by the mucosal environment. Indeed, saliva has been shown to contain substances with anti-HSV activity. In the current study, we investigated the anti-HSV-1 activity of human lactoferrin (hLf) and lysozyme (hLz), two highly cationic polypeptides of the mucosal innate defence system. HLf blocked HSV-1 infection at multiple steps of the viral replication cycle, whereas lysozyme displayed no anti-HSV-1 activity. Preincubation of HSV-1 virions and presence of hLf during or after viral absorption period or for the entire HSV-1 infection cycle inhibited HSV-1 infection by reducing both the plaque count and plaque size in a dose- and virus strain-dependent manner. Cell-to-cell spread of wild-type HSV-1 and the strain gC-39, deleted of glycoprotein C, was dramatically reduced, but the cell-to-cell spread of HSV-1 Rid1, harboring a mutated gD and thus unable to react with the cellular HVEM receptor, remained unchanged. This suggests that the inhibition of cell-to-cell spread is mediated by effects on gD or its cellular counterparts. Our results show that the cationic nature is not a major determinant in the anti-HSV action of mucosal innate cationic polypeptides, since whereas hLf inhibited HSV-1 infection efficiently, hLz had no HSV-1 inhibiting activity. Our results show that in addition to inhibiting the adsorption and post-attachment events of HSV-1 infection, hLf is also able to neutralize HSV-1 and that the inhibition of cell-to-cell spread involves viral gD. These results suggest that Lf may have a significant role in the modulation of HSV-1 infection in the oral cavity as well as in the genital mucosa, the major sites of HSV-1 infection.

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
BACKGROUND Reactivation of herpes simplex virus-1 (HSV-1) can result in recurrent herpes labialis lesions (RHL) and in oral shedding of virus. This study utilized polymerase chain reaction (PCR) to document the frequency and quantity of such shedding. METHODS Thirty adults with greater than three RHL episodes per year were followed through one recurrence. They collected swabs for PCR every 12 h starting at prodrome and for 10 days thereafter. Shedding was analyzed with regard to frequency, timing and quantity. RESULTS HSV-1 was detectable in 87% of participants for a mean of 4 days. Shedding occurred most frequently during the vesicle/ulcer stage (91% of subjects), but was common in both clinical and subclinical stages (50% vs. 23%, average log DNA copy number/ml(2) 2.6 vs. 1.4). CONCLUSION The majority of RHL patients shed viral DNA. Shedding occurred before and after the appearance of clinical lesions. Such findings may be useful in designing methods to reduce viral shedding and prevent transmission.

Abstract
A wide variety of both DNA and RNA viruses affect the oral cavity. When considered in conjunction with cutaneous features, careful examination of the oral mucosa and oropharynx aids the clinician in making a diagnosis. Examination of the oral cavity should be incorporated as a regular component of the dermatologic examination because diagnostic clues are readily available to assist in the evaluation of infectious processes.

Abstract
A European panel of physicians reviewed the current treatments and perceptions of recurrent genital herpes (GH) across the continent. The panel consisted of specialists in dermatology and venereology from France, Finland, Germany, Italy, Norway, Spain, Sweden and the UK. A wide variety of factors that influence GH management were considered, including different health delivery systems, funding and cultural differences. The poor awareness of GH among both the general public and physicians was highlighted. The effectiveness of GH management was then examined from a patient's viewpoint, including the confirmation of the diagnosis, information and counselling about GH, as well as prescriptions for treatment. It was agreed that both physicians and patients often feel uncomfortable about discussing the disease, and that a European-wide effort is needed to re-educate patients and physicians about GH. The panel identified clear and unmet needs to manage a patient with clinical recurrences and to attempt to reduce the risk of GH transmission. Finally, resiquimod, an immune response modifier, was considered as a potential treatment option for GH.

Abstract
Although herpes simplex virus (HSV) has been detected in the peripheral blood of immunocompromised patients and in neonates with disseminated disease, the extent to which the virus may be present in the blood during a localized infection in otherwise healthy patients is still unknown. Literature on patterns of HSV shedding into the oral cavity at the prodromal stage of the disease, during recurrences, and also during asymptomatic periods is still lacking. The present study aims at the detection of HSV DNA in the serum and oral secretions during acute herpes labialis using a highly sensitive technique, the polymerase chain reaction (PCR). The study included 10 patients with acute herpes labialis and five healthy controls. Using PCR, herpes simplex virus DNA was detected in the serum of seven patients (70%) and in the saliva of nine patients (90%). One of the control cases showed positive HSV DNA in the saliva (20%). There was good statistical agreement between the presence of HSV DNA in the serum and saliva. Frequency of attacks, patient's age, and gender had no statistically significant effect on the presence of the virus in serum or in saliva. It is concluded that HSV viremia during attacks of recurrent herpes simplex is more frequent than previously appreciated.

Abstract
Saliva may contribute to a lowering of the infectious herpes simplex virus (HSV) dose during transmission and consequently abrogate infection or lead to decreased reactivation. To test this hypothesis, we assayed saliva for innate defense factors, immunoglobulin content, and the capacity to interfere with HSV infection. Serum or salivary anti-HSV IgG levels did not correlate with control of recurrent labial herpes (RLH) and were significantly higher in subjects with RLH compared with asymptomatic seropositive subjects. Although no differences in levels or output rate of innate defense factors between the groups were observed, the salivary neutralizing activity correlated with lactoferrin and hypothiocyanite concentrations in the asymptomatic seropositive group. Our results suggest that saliva contains factors, in addition to anti-HSV immunoglobulins, that neutralize HSV and may indirectly contribute to the control of RLH.

Abstract
PURPOSE To review the changing epidemiology of herpes simplex disease and correlate it with the epidemiology of ocular herpes simplex disease. METHOD A review of pertinent reports in the world literature about the epidemiology of herpes simplex and specifically about ocular herpes simplex. RESULTS In developed countries, many individuals are reaching adolescence and adulthood without prior herpesvirus infection. Herpes simplex genital infection is increasing at a rapid rate in sexually active adolescents and adults, with about one in six adults now infected in the United States. Similar statistics are confirmatory worldwide in developed countries. Active herpes simplex infection is a risk factor for acquisition of human immunodeficiency virus. The Herpetic Eye Disease Study, as well as prior studies from Moorfields Eye Hospital and the Mayo Clinic in Rochester, Minnesota, provides us with the epidemiology of ocular herpes simplex. Recent studies suggest an older age of onset and perhaps overall more severe ocular disease as compared with the older literature. CONCLUSIONS Herpes simplex is a significant health concern at present with genital infections increasing in epidemic proportions. This is also reflected in a rise in the incidence of neonatal herpes. Herpes simplex virus type 1 (HSV-1) infection is being acquired for the first time in an older age group. A significant and increasing proportion of genital herpes is caused by HSV-1. Serologic studies are no longer as useful in distinguishing orofacial herpes from genital herpes. More acute retinal necrosis syndrome cases are associated with HSV-2. Speculation about the future of ocular herpes is made based on this changing epidemiology.

Abstract
Reactivation in the oral cavity either symptomatically (recrudescence) or without symptoms (recurrence) may contribute to the transmission of herpes simplex virus type 1 (HSV-1), especially in critical areas of exposure such as dentistry. In order to measure the frequency of HSV-1 reactivation, nested polymerase chain reaction (PCR) was performed on oral swabs collected from 30 healthy people over a period of 58-161 days. In total 19 of 25 (76%) seropositive people were PCR-positive at least once, 6 of these 19 (32%) had recrudescence and 13 (68%) had only asymptomatic reactivation. Frequencies of additional recurrences were higher in people showing symptomatic reactivation than in those who had only recurrences. Recrudescence is a risk factor for elevated levels of asymptomatic HSV-shedding. In most cases HSV-1 was detected only by nested PCR investigated by early onset of therapy or time span before sampling.

Abstract
BACKGROUND Reactivation of herpes simplex virus-1 (HSV-1) after facial resurfacing has led to severe outbreaks, delayed reepitheliazation, and scarring. Current recommendations regarding the dosing of antivirals used prophylactically are based mostly on anecdotal experience. No studies have addressed the question of when such antiviral prophylaxis should begin. OBJECTIVE The purpose of this study was to compare the efficacy of valacyclovir used as an antiviral prophylaxis when started the morning before versus the morning of facial resurfacing procedures. METHODS Eighty-four patients who presented for facial resurfacing were enrolled. Resurfacing was performed using laser (CO2, Er:YAG), chemical peeling, dermabrasion/dermasanding, or some combination of these techniques. Patients were randomly assigned to start valacyclovir 500 mg twice daily either the morning before or the morning of the procedure. Viral cultures were performed at baseline on all patients, at any sign of infection, and at the end of the 14-day treatment period. All patients were followed for 21 days postoperatively. RESULTS Valacyclovir was 100% effective in the prevention of HSV reactivation in both regimens with no adverse effects reported. CONCLUSION This study demonstrates the efficacy of valacyclovir as a preventive agent against HSV outbreaks following facial resurfacing whether started the day before or the day of surgery.

Abstract
In some individuals a local herpetic lesion precipitates a generalized inflammation of the skin, designated as erythema multiforme (EM). We determined the frequencies of the immune response genes of the HLA system by molecular HLA class II typing in 46 patients with EM and in many of their family members. Allele frequencies were correlated with disease form and disease-inducing factors. We found that specific complications of HSV infection occur preferentially in patients with certain HLA-DQB1 alleles. In 21 of the 46 patients EM was induced by recurrent HSV infection. Thirteen of these patients showing only minor or no involvement of mucous membranes had the HLA allele DQB1*0302 (phenotype frequency 61.9% versus 18.8% in controls, p corr = 0.0008) and all three patients with major involvement of mucous membranes had the rare HLA allele DQB1*0402 (phenotype frequency in controls 6,4%, p corr = 0.017).

Abstract
Herpes simplex virus type 1 (HSV-1) and, to a lesser extent, type 2 (HSV-2) are the aetiological agents of recrudescent herpes labialis (RHL). The available literature on patterns of HSV-1 shedding into the oral cavity at the prodromal stage of disease, during recrudescences and also during asymptomatic periods, is reviewed, as are the potential sources of virus and the known trigger factors leading to viral reactivation. Attention is given to the methodologies in use for the detection of HSV-1 and the relevance to the risk of cross-infection in surgery. This review also discusses the increase in incidence of HSV-1 genital infections and the significance of salivary inhibitors of the herpes simplex type 1 virus.

Abstract
Orolabial human infections with herpes simplex virus type 1 (HSV-1) are very common; following the primary epidermal infection, the virus is retained in a latent form in the trigeminal ganglia from where it can reactivate and cause a recrudescent lesion. Recrudescences are triggered by various stimuli including exposure to sunlight. In this review three categories of mouse models are used to examine the effects of UV irradiation on HSV infections: these are UV exposure prior to primary infection, UV exposure as a triggering event for recrudescence and UV exposure prior to challenge with virus in mice already immunized to HSV. In each of these models immunosuppression occurs, which is manifest, in some instances, in increased morbidity or an increased rate of recrudescence. Where known, the immunological mechanisms involved in the models are summarized and their relevance to human infections considered.

Abstract
Oral and intravenous acyclovir formulations provide effective virostasis against many herpes viruses infections, especially severe herpes simplex or varicella-zoster infections in ambulatory and immunocompromised patients. The therapeutic virostatic efficacy of topical acyclovir formulations requires further development, however, especially for orolabial herpetic infections.

Abstract
Langerhans cells are part of a vast system of potent antigen-presenting cells known under the name of dendritic cells. During the last decade, much has been learned on dendritic cell involvement in the immune response to infectious diseases. This review briefly summarizes our current understanding of the role played by Langerhans cells and other dendritic cells in the pathogenesis of DNA and RNA virus infections. These data may form the basis for the development of innovative approaches in the diagnosis, prevention, and treatment of viral diseases.

Abstract
Interleukin-1, tumour necrosis factor-alpha and interleukin-6 are considered to be major mediators of inflammatory processes. In the present study, cytokine gene transcription was detected by the polymerase chain reaction technique during cutaneous and intraperitoneal infection with herpes simplex virus-1. Epidermal cell suspensions obtained from mice infected with herpes simplex virus-1 in the ear pinna were enriched or depleted in Langerhans cells by immunomagnetic fractionation. Herpes simplex virus-1 infection in the skin was found to induce interleukin-1 beta, tumour necrosis factor-alpha and interleukin-6 gene transcription in keratinocytes at 24 hours post-infection. Gene transcription declined by 48 hours post-infection. Induction of interleukin-1 beta and tumour necrosis factor-alpha but not of IL-6 gene transcription was detected in Langerhans cells obtained from infected mice at 24 hours post-infection. In order to study cytokine gene transcription during intraperitoneal infection with herpes simplex virus-1, peritoneal exudate cells were obtained from infected mice. Maximal levels of interleukin-1 beta, tumour necrosis factor-alpha, and interleukin-6 mRNA were found in peritoneal exudate cells 6 hours after infection. RNA transcription declined at 24 hours post-infection and was no longer detectable at 48 hours post-infection. Since the higher susceptibility of newborn mice to intraperitoneal herpes simplex virus-1 infection has been suggested to be related to defective cytokine production, cytokine gene transcription was compared in peritoneal exudate cells obtained from infected newborn and adult mice. No significant differences in interleukin-1 beta, tumour necrosis factor-alpha and interleukin-6 gene expression were observed in peritoneal exudate cells obtained from newborn mice as compared with adult mice. In conclusion, cutaneous and intraperitoneal infection with herpes simplex virus-1 induces interleukin-1 beta, tumour necrosis factor-alpha and interleukin-6 gene transcription in epidermal and peritoneal exudate cells.
