Abstract
The incidence of sexually transmitted infections (STIs) is increasing in Spain. Suppurative STIs are one of the most frequent reasons for consultation in specialized centers. The reason for suppurative STIs is multiple and their empirical treatment varies with the currently growing problem of antimicrobial resistance. Dermatologists are trained and prepared to treat these diseases, but their correct management requires active knowledge of national and international guidelines. The present document updates, reviews and summarizes the main expert recommendations on the management and treatment of these STIs.

Abstract
This guideline intents to offer guidance on the diagnosis and management of patients with gastrointestinal symptoms and a suspected sexually transmitted cause. Proctitis is defined as an inflammatory syndrome of the anal canal and/or the rectum. Infectious proctitis can be sexually transmitted via genital-anal mucosal contact, but some also via digital contact and toys. Neisseria gonorrhoeae, Chlamydia trachomatis (including lymphogranuloma venereum), Treponema pallidum and herpes simplex virus are the most common sexually transmitted anorectal pathogens. Shigellosis can be transferred via oral-anal contact and may lead to proctocolitis or enteritis. Although most studies on these infections have concentrated on men who have sex with men (MSM), women having anal intercourse may also be at risk. A presumptive clinical diagnosis of proctitis can be made when there are symptoms and signs, and a definitive diagnosis when the results of laboratory tests are available. The symptoms of proctitis include anorectal itching, pain, tenesmus, bleeding, constipation and discharge in and around the anal canal. The majority of rectal chlamydia and gonococcal infections are asymptomatic and can only be detected by laboratory tests. Therefore, especially when there is a history of receptive anal contact, exclusion of anorectal infections is generally indicated as part of standard screening for sexually transmitted infections (STIs). Condom use does not guarantee protection from STIs, which are often spread without penile penetration. New in this updated guideline is: (i) lymphogranuloma venereum proctitis is increasingly found in HIV-negative MSM, (ii) anorectal Mycoplasma genitalium infection should be considered in patients with symptomatic proctitis after exclusion of other common causations such N. gonorrhoeae, C. trachomatis, syphilis and herpes, (iii) intestinal spirochetosis incidentally found in colonic biopsies should not be confused with syphilis, and (iv) traumatic causes of proctitis should be considered in sexually active patients.

Abstract
Objective: To compare laboratory tests that can simultaneously detect and type herpes simplex virus (HSV) directly from the genital ulcer specimens in clinically suspected cases of genital herpes. Materials and Methods: A study was conducted over 10 months and 44 adult male and female patients clinically suspected with genital herpes were recruited. Genital ulcer swab specimens were subjected to glycoprotein-G gene-based conventional polymerase chain reaction (PCR) and commercially available direct fluorescent antibody (DFA) test and the results were compared. Results: PCR for HSV was positive in 82% (36/44) cases. DFA was positive in 68.2% (30/44) cases. There was 100% agreement between HSV types detected by DFA and PCR. The strength of agreement between the results was better in primary genital herpes than recurrent cases. Conclusion: PCR was found to be better in the detection of HSV in recurrent genital herpes patients. It is a better modality, especially when genital herpes clinically presents with ulcerative or crusted lesions, and is also a cheaper alternative as compared to DFA.

Abstract
These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of HSV in the pre- and post-transplant period. A majority of transplant recipients are seropositive for HSV-1 or 2. Compared with immunocompetent persons, SOT recipients shed HSV more frequently, have more severe clinical manifestations, and are slower to respond to therapy. Most HSV infection is diagnosed on clinical grounds, but patients may present with atypical lesions and/or other clinical manifestations. Acquisition from the donor is rare. Polymerase chain reaction is the preferred diagnostic test unless culture is needed for resistance testing. For limited mucocutaneous lesions, oral therapy can be used; however, in severe, disseminated, visceral or CNS involvement, acyclovir doses of up to 10 mg/kg every 8 hours intravenously should be initiated. Acyclovir-resistant HSV is less common in SOT patients than in HSCT and can be treated with foscarnet, though other novel therapies are currently under investigation. HSV-specific prophylaxis should be considered for all HSV-1 and HSV-2-seropositive organ recipients who are not receiving antiviral medication for CMV prevention that has activity against HSV.

Abstract
Genital herpes is a sexually transmitted disease caused by herpes simplex virus type1 (HSV-1) and type2 (HSV-2) belonging to the alphaherpesvirus family, that includes the varicella zoster virus. HSV infection continues to be the most common cause of vulvar ulcers among the sexually active population. Its incidence increases every year. This review summarises the microbiology of the virus, pathogenesis and infection in genitalia, clinical manifestations and correct identification, the different laboratory diagnostic methods, and choice of the correct treatment according to the first infection, recurrence or special cases. Finally, the cost of routine herpes simplex virus infection is analysed.

Abstract
Genital herpes is one of the commonest sexually transmitted infections worldwide. Using the best available evidence, this guideline recommends strategies for diagnosis, management, and follow-up of the condition as well as for minimising transmission. Early recognition and initiation of therapy is key and may reduce the duration of illness or avoid hospitalisation with complications, including urinary retention, meningism, or severe systemic illness. The guideline covers a range of common clinical scenarios, such as recurrent genital herpes, infection during pregnancy, and co-infection with human immunodeficiency virus.

Abstract
Caused by the herpes simplex virus (HSV), herpes is a viral infection that is one of the most widespread diseases worldwide. Here we present a computational sensing technique for specific detection of HSV using both viral immuno-specificity and the physical size range of the viruses. This label-free approach involves a compact and cost-effective holographic on-chip microscope and a surface-functionalized glass substrate prepared to specifically capture the target viruses. To enhance the optical signatures of individual viruses and increase their signal-to-noise ratio, self-assembled polyethylene glycol based nanolenses are rapidly formed around each virus particle captured on the substrate using a portable interface. Holographic shadows of specifically captured viruses that are surrounded by these self-assembled nanolenses are then reconstructed, and the phase image is used for automated quantification of the size of each particle within our large field-of-view, ~30 mm2. The combination of viral immuno-specificity due to surface functionalization and the physical size measurements enabled by holographic imaging is used to sensitively detect and enumerate HSV particles using our compact and cost-effective platform. This computational sensing technique can find numerous uses in global health related applications in resource-limited environments.

Abstract
INTRODUCTION HSV-1 and HSV-2 are among the most common causes of sexually transmitted infections (stis) globally. these infections are strongly associated with increased risk of hiv acquisition and rare, but devastating, neonatal disease. available treatment options can reduce HSV transmission and improve quality of life. accurate diagnosis early in disease can improve patient management. Areas covered: This paper describes the clinical manifestations of HSV infection often used for clinical diagnostic purposes. The paper then describes the evolution of laboratory diagnostic assays. Serology, culture and molecular diagnostics are described since all are currently in use. The features and performance characteristics of the cobas 4800 HSV1 and HSV2 Test (cobas HSV) on the cobas 4800® system (cobas 4800) are described in detail. Expert commentary: Diagnosis of HSV has historically been unreliable or technically difficult, but the availability of molecular assays such as the cobas HSV test for detection and typing of herpes can improve our ability to correctly manage this disease. Utilization of tools such as the cobas HSV assay may help shorten the time to accurate diagnosis and treatment thus potentially reducing the risk of transmission and the global burden of HSV.

Abstract
Etiology, transmission and protection: Herpes simplex virus-2 (HSV-2) is a leading cause of sexually transmitted infections with recurring manifestations throughout the lifetime of infected hosts. Currently no effective vaccines or prophylactics exist that provide complete protection or immunity from the virus, which is endemic throughout the world. Pathology/Symptomatology: Primary and recurrent infections result in lesions and inflammation around the genital area and the latter accounts for majority of genital herpes instances. Immunocompromised patients including neonates are susceptible to additional systemic infections including debilitating consequences of nervous system inflammation. Epidemiology, incidence and prevalence: More than 500 million people are infected worldwide and most reported cases involve the age groups between 16-40 years, which coincides with an increase in sexual activity among this age group. While these numbers are an estimate, the actual numbers may be underestimated as many people are asymptomatic or do not report the symptoms. Treatment and curability: Currently prescribed medications, mostly nucleoside analogs, only reduce the symptoms caused by an active infection, but do not eliminate the virus or reduce latency. Therefore, no cure exists against genital herpes and infected patients suffer from periodic recurrences of disease symptoms for their entire lives. Molecular mechanisms of infection: The last few decades have generated many new advances in our understanding of the mechanisms that drive HSV infection. The viral entry receptors such as nectin-1 and HVEM have been identified, cytoskeletal signaling and membrane structures such as filopodia have been directly implicated in viral entry, host motor proteins and their viral ligands have been shown to facilitate capsid transport and many host and HSV proteins have been identified that help with viral replication and pathogenesis. New understanding has emerged on the role of autophagy and other innate immune mechanisms that are subverted to enhance HSV pathogenesis. This review summarizes our current understanding of HSV-2 and associated diseases and available or upcoming new treatments.

Abstract
PCR methods are nowadays between the most rapid and sensitive methods for screening and diagnosing herpes simplex virus (HSV) type 1 and 2. The aim of this study was to analyze the reliability, accuracy, and usefulness of the new assay HSV OligoGen kit in comparison with the Roche LightCycler HSV ½ Qual Kit assay for the detection of HSV in clinical samples. For this analysis, a prospective study was designed for detection of HSV-1 and HSV-2 including 110 ulcer specimens, 48 urine, 48 endocervical, 43 cerebral spinal fluids, 4 urethral and 3 pharyngeal swabs that were sent from a regional STI clinic or an Intensive Clinical Unit, both in Seville, Spain. In comparison to the Roche LightCycler HSV ½ Qual Kit assay, sensitivity, specificity, positive and negative predicative values, and kappa value for HSV detection using the HSV OligoGen kit were 96.2%, 100%, 100%, 98.3%, and 0.97 for HSV-1, respectively. For HSV-2, the corresponding values were 98.3%, 100%, 100%, 99.5%, and 0.98, respectively. Statistical data obtained in this study confirms the usefulness and reliable results of this new assay.

Abstract
Chancroid, lymphogranuloma venereum, and granuloma inguinale may be considered as tropical venereal diseases. These diseases were a major diagnostic and therapeutic challenge in past centuries. Currently, patients with these bacterial infections that are endemic to the tropics occasionally consult with dermatologists in temperate climates. Due to the increasing frequency of travel to the tropics for tourism and work, as well as the increasing number of immigrants from these areas, it is important for dermatologists practicing in temperate climates to be familiar with the dermatologic manifestations of such infections, to be prepared to diagnose these diseases, and to treat these patients. All three "tropical" infections respond well to prompt and appropriate antimicrobial treatment, although herpes progenitalis still cannot be cured, and the number of people infected keeps growing; moreover, genital herpes can be transmitted by viral shedding before and after the visual signs or symptoms. Acyclovir, valacyclovir, and famciclovir can shorten outbreaks and make them less severe or even stop them from happening. There is currently no etiologic treatment for molluscum contagiosum, and the majority of treatment options are mechanical, causing a certain degree of discomfort. The molluscum contagiosum virus, unlike the other infectious agents mentioned, does not invade the skin.

Abstract
Since the type of herpes simplex virus (HSV) infection affects prognosis and subsequent counseling, type-specific testing to distinguish HSV-1 from HSV-2 is always recommended. Although PCR has been the diagnostic standard method for HSV infections of the central nervous system, until now viral culture has been the test of choice for HSV genital infection. However, HSV PCR, with its consistently and substantially higher rate of HSV detection, could replace viral culture as the gold standard for the diagnosis of genital herpes in people with active mucocutaneous lesions, regardless of anatomic location or viral type. Alternatively, antigen detection—an immunofluorescence test or enzyme immunoassay from samples from symptomatic patients--could be employed, but HSV type determination is of importance. Type-specific serology based on glycoprotein G should be used for detecting asymptomatic individuals but widespread screening for HSV antibodies is not recommended. In conclusion, rapid and accurate laboratory diagnosis of HSV is now become a necessity, given the difficulty in making the clinical diagnosis of HSV, the growing worldwide prevalence of genital herpes and the availability of effective antiviral therapy.

Abstract
It is becoming increasingly clear that the herpes simplex viruses (HSVs) 1 and 2 constitute a major, global, public health problem, particularly as genital herpes is implicated in the causation of a significant percentage of onwards transmission of the HIV virus. A major factor in the transmission of HSV is that most carriers are unaware of their diagnosis. In the last few years, the development of nucleic acid amplification technology and type-specific antibody serology to test for HSV-1 and -2 has contributed significantly to the accurate diagnosis of these infections. Despite guidance to the contrary, there is still much use of less sensitive tests such as viral culture and antibody testing based on crude antigen. It is essential that we use the most sensitive and specific diagnostic tests if we are to curb this epidemic.

Abstract
Proctitis is defined as an inflammatory syndrome of the distal 10-12 cm of the anal canal, also called the rectum. Infectious proctitis can be sexually transmitted via genital-anal mucosal contact, but some also via mutual masturbation.N. gonorrhoeae,C. trachomatis(including lymphogranuloma venereum), Herpes Simplex Virus andT. pallidumare the most common sexually transmitted anorectal pathogens. Shigellosis can be transferred via oral-anal contact and may lead to proctocolitis or enteritis. Although most studies on these infections have concentrated on men who have sex with men (MSM), a significant proportion of women have anal intercourse and therefore may also be at risk. A presumptive clinical diagnosis of proctitis can be made when there are symptoms and signs, and a definitive diagnosis when the results of laboratory tests are available. The symptoms of proctitis include anorectal itching, pain, cramps (tenesmus) and discharge in and around the anal canal. Asymptomatic proctitis occurs frequently and can only be detected by laboratory tests. The majority of rectal chlamydia and gonococcal infections are asymptomatic. Therefore when there is a history of receptive anal contact, exclusion of anorectal infections is generally indicated as part of standard screening for sexually transmitted infections (STIs). Condom use does not guarantee protection from bacterial and protozoan STIs, which are often spread without penile penetration.

Abstract
The Simplexa HSV 1 & 2 direct PCR assay was compared with conventional cell culture, cytospin-enhanced direct fluorescent antibody (DFA), and a laboratory-developed real-time TaqMan PCR (LDT HSV PCR) using extracted nucleic acid for the detection of herpes simplex virus (HSV) in dermal, genital, mouth, ocular, and other swab samples. One hundred seventy-one swabs were tested prospectively, and 58 were positive for HSV (34 HSV-1 and 24 HSV-2). Cytospin-DFA detected 50 (86.2%), conventional cell culture 51 (87.9%), Simplexa direct 55 (94.8%), and LDT HSV PCR 57 (98.3%) of 58 true positives. Simplexa direct detected more positives than DFA and culture, but the differences were not significant (P = 0.0736 and P = 0.3711, respectively, by the McNemar test). Samples that were positive by all methods (n = 48) were strong positives (LDT cycle threshold [CT] value, 14.4 to 26.1). One strongly positive sample was falsely negative by LDT HSV PCR due to a failure of TaqMan probe binding. Three samples falsely negative by Simplexa direct had high CT values by LDT HSV PCR (LDT CT, 35.8 to 38.2). Omission of the DNA extraction step by Simplexa direct led to a drop in sensitivity compared to the sensitivity of LDT HSV PCR using extracted samples (94.8% versus 98.3%, respectively), but the difference was not significant (P = 0.6171). Simplexa HSV 1 & 2 direct PCR was the most expensive but required the least training of the assays used, had the lowest hands-on time and fastest assay time (75 min, versus 3 h by LDT HSV PCR), and provided the HSV type.

Abstract
Herpes simplex virus (HSV) is one of the most common, yet frequently overlooked, sexually transmitted infections. Since the type of HSV infection affects prognosis and subsequent counseling, type-specific testing to distinguish HSV-1 from HSV-2 is recommended. Although PCR has been the diagnostic standard for HSV infections of the central nervous system, until now viral culture has been the test of choice for HSV genital infection. However, HSV PCR, with its consistently and substantially higher rate of HSV detection, will likely replace viral culture as the gold standard for the diagnosis of genital herpes in people with active mucocutaneous lesions, regardless of anatomic location or viral type. Alternatively, type-specific serologic tests based on glycoprotein G should be the test of choice to establish the diagnosis of HSV infection when no active lesion is present. Given the difficulty in making the clinical diagnosis of HSV, the growing worldwide prevalence of genital herpes and the availability of effective antiviral therapy, there is an increased demand for rapid, accurate laboratory diagnosis of patients with HSV.

Abstract
Clinical diagnosis of genital herpes simplex virus (HSV) (GH) infection is insensitive and non-specific and requires laboratory confirmation. In this study we compared viral culture and the amplification of HSV DNA by polymerase chain reaction (PCR) with respect to turnaround time and cost. We compared 182 swabs submitted to our laboratory between March and May 2005, which were tested using MRC-5 cell culture, with 168 genital swabs submitted during the same months in 2006, and were tested by PCR. We concluded that PCR testing in our laboratory has significantly improved the turnaround time, with 68.4% of tests having been reported in less than 24 hours. This in turn significantly improved the service provided for the diagnosis of genital herpes without additional costs.

Abstract
BACKGROUND Successful conduct of HIV vaccine efficacy trials entails identification and enrollment of at-risk populations, assessment of appropriate end points as measures of vaccine efficacy for prevention of HIV acquisition, and amelioration of disease course among infected vaccinees, as well as identification of potential confounders or effect modifiers. Although not invariably useful and bringing their own cost in terms of measurement and validation, a variety of biomarkers may aid at each stage of trial conduct. METHODS A review of selected articles, chosen based on quality, relevance of the biomarker to HIV vaccine trials, and availability of the publication, was conducted. The authors also drew experience from current trials and other planned or ongoing trials. CONCLUSIONS Biomarkers are available to assess HIV incidence in potential study populations, but care is needed in interpreting results of these assays. During trial conduct, sexually transmitted infections such as herpes simplex virus type 2 may act as effect modifiers on primary and secondary end points, including HIV incidence and set point viral load. The utility of sexually transmitted infection biomarkers will likely depend heavily on local epidemiology at clinical trial sites. Analyses from recent large HIV vaccine efficacy trials point to the complexities in interpreting trial results and underscore the potential utility of biomarkers in evaluating confounding and effect modification.

Abstract
Historically, the diagnosis of sexually transmitted diseases (STDs) has been difficult. The introduction of molecular biology techniques in microbiological diagnosis and their application to non-invasive samples has produced significant advances in the diagnosis of these diseases. Overall, detection of Neisseria gonorrhoeae by molecular biology techniques provides a presumptive diagnosis and requires confirmation by culture in areas with a low prevalence. For Chlamydia trachomatis infections, these techniques are considered to be the most sensitive and specific procedures for mass screening studies, as well as for the diagnosis of symptomatic patients. Diagnosis of Mycoplasma genitalium infection by culture is very slow and consequently molecular techniques are the only procedures that can provide relevant diagnostic information. For Treponema pallidum, molecular techniques can provide direct benefits in the diagnosis of infection. Molecular techniques are not established for the routine diagnosis of donovanosis, but can be recommended when performed by experts. Molecular methods are advisable in Haemophilus ducreyi, because of the difficulties of culture and its low sensitivity. In genital herpes, molecular techniques have begun to be recommended for routine diagnosis and could soon become the technique of choice. For other genital infections, bacterial vaginosis, vulvovaginal candidosis and trichomoniasis, diagnosis by molecular methods is poorly established. With genital warts, techniques available for screening and genotyping of endocervical samples could be used for certain populations, but are not validated for this purpose.

Abstract
A retrospective analysis of patients, who have been on long-term suppressive therapy for recurrent episodes of herpes simplex (HSV) in a university hospital, was performed and the findings were documented and orchestrated into bar graphs. The study involved patients between the years 2000 and 2007, both inclusive. The results were compared with the British Association for Sexual Health and HIV guidelines. Eighty-two percent (57) had had the infection for at least 12 months at the start of therapy and 78.2% (54) had at least six recurrences per year before the start of treatment. Indeed, only four patients (5.8%) had a treatment interruption at 12 months or less; also only 11 patients (15.9%) had less than six outbreaks per year at the start of treatment. The former is not in-line and the latter is in-line with the guidelines.

Abstract
In the last decade, cases of sexually-transmitted infections (STIs) have progressively increased in Europe. The reasons for this increase are unclear, but may involve changes in social behavior, migration and international travel, coupled with the emergence of risk groups that have not been taken into sufficient consideration to date. The routine use of molecular diagnostic techniques for many of these infections has solved many problems of sensitivity and the suitability of samples for microbiological diagnosis: non-invasive samples can be used, which has undoubtedly contributed to the increase in the number of cases. Moreover, molecular methods have also been introduced for antibiotic and antiviral susceptibility testing, as well as for molecular characterization of clinical isolates. All of these factors, together with the approval of the vaccine against the human papillomavirus, have changed the landscape of STIs across Europe.

Abstract
OBJECTIVE To determine the acceptability to pregnant women and their health care providers of a rapid test for genital herpes simplex virus (HSV) in labour. METHODS A cross-sectional survey was conducted with outpatient pregnant women and their health care providers (obstetricians, family physicians and midwives) at BC Women's Hospital and Health Centre. RESULTS Of pregnant women approached, 207 (92%) completed the survey; 90% reported no history of genital herpes. Rapid HSV testing in labour was acceptable to 85% of pregnant women. Among the 133 women who were planning a vaginal delivery, 63% were willing to consider delivery by Caesarean section and 53% were willing to consider intrapartum anti-viral medications if HSV was present in the genital tract. Of 51 health care providers surveyed, 98% indicated interest in knowing if their patient had a newly acquired HSV infection, while 84% indicated interest in knowing if the patient had a reactivation of infection. If HSV was detected in their patient's genital tract, 36% indicated they would recommend a Caesarean section, and 25% would consider antiviral medication as an investigational intrapartum treatment. Interestingly, both of these proportions increased if the patient had ruptured membranes for more than four hours. CONCLUSION Most pregnant women and their health care providers are receptive to the use of a rapid polymerase chain reaction test to detect genital HSV shedding in labour. This supports the development of HSV rapid testing and antiviral therapy trials in the labour setting.

Abstract
Sexually transmitted infections (STIs) constitute an important world-wide public health problem. The use of sensitive and specific laboratory methods for diagnosing this condition is crucial to reduce the transmission and sequelae of STI. The present review describes current microbiological methods for the diagnosis of STIs. Neisseria gonorrhoeae and Chlamydia trachomatis are the pathogens most frequently involved in urethral and cervical infection. Culture continues to be the gold standard for diagnosing gonorrhea. Nucleic acid amplification assays are considered the new gold standard for C. trachomatis, although culture is till the most specific technique. Genital ulcers due to Treponema pallidum, Haemophilus ducreyi, or herpes simplex virus have little clinical and bacteriological correlation; therefore, it is essential to establish the microbiological diagnosis. Lesions present in the primary or secondary period of syphilis can be diagnosed by dark field microscopy. Serologic diagnosis for the remaining periods is based on non-treponemal tests associated with confirmatory treponemal tests. Cell culture is considered the gold standard for herpes simplex virus although molecular methods also have a sensitivity and specificity near 100%. Currently, microbiologic diagnosis of H. ducreyi and venereal lymphogranuloma is achieved with the use of molecular methods on samples obtained from the ulceration or lymph adenopathy. The diagnosis of genital warts in immunocompetent patients is based on clinical findings in most cases because the lesions are sufficiently characteristic. Culture is considered the reference method in Trichomonas vaginalis infection.

Abstract
Genital herpes is the main cause of genital ulcers worldwide; the prevalence of herpes simplex virus (HSV) type 2 infections in the general population ranges from 10% to 60%. Most genital herpes is caused by HSV-2, although HSV-1 accounts for about half of new cases in developed countries. The risk of HIV acquisition is three times higher in people with HSV-2. Neonatal herpes is an uncommon but serious complication of genital herpes. Most genital HSV-2 infections are unrecognised and undiagnosed; infected individuals, even with mild symptoms, shed HSV, and can infect sexual partners. Since clinical diagnosis is neither sensitive nor specific, virological and type-specific serological tests should be used routinely. Oral antiviral drugs for HSV infections are safe and effective and can be used both to treat episodes and to prevent recurrences. Antiviral treatment of the infected partners and condom use reduce the risk of sexual transmission of HSV-2.

Abstract
BACKGROUND Children who may have been sexually abused are examined in many different settings by medical providers with variable levels of education and experience in this special area of practice. Therefore, there is a need for a consistent evidence-based approach that is agreed upon by medical experts. OBJECTIVES To develop and provide guidelines and recommendations for performing and interpreting findings of the medical evaluation of children referred for sexual abuse medical evaluations, and to provide guidelines for the education, oversight, and peer review process for clinicians who provide assessments for suspected child sexual abuse. METHODS Participation from medical providers was solicited through postings on the Internet list-serves administered by Cornell University (Special Interest Group in Child Abuse), and by the Ray E. Helfer Society, an honorary society for physician specialists in child abuse diagnosis and treatment. The guidelines were developed through review and critique of published research studies, discussions in focus group meetings at child abuse medical conferences, and ongoing communication leading to revision of draft documents. RESULTS Groups of 10 to 40 physician experts met at child abuse conferences between January 2002 and January 2005 to revise the table summarizing the interpretation of physical and laboratory findings in suspected child sexual abuse and to develop guidelines for medical care for sexually abused children. Between January and December 2005, the guidelines were expanded and revised. CONCLUSIONS The guidelines presented here reflect the current knowledge, recommended clinical approaches, and required competencies in the field of child sexual abuse medical evaluation.

Abstract
Significant synergistic interactions have been observed between HIV and herpes simplex virus (HSV). HIV-induced immune compromise can cause frequent and persistent HSV disease, while poorly controlled HSV replication may influence HIV pathogenicity and transmission. HSV-2 seroprevalence is high in HIV-infected cohorts worldwide, with rates of over 80% for HSV-1 and ranging from 33% to more than 80% for HSV-2. As seen in HIV-negative individuals, HSV-2 coinfection is associated with female gender, older age and black ethnicity. HSV infection is commonly under-diagnosed in HIV-infected individuals, although the use of PCR for HSV detection in mucocutaneous swabs and HSV type-specific serology can improve the diagnostic yield. In HIV-1-infected patients with frequent clinical episodes of HSV reactivation, suppressive antiviral therapy may prove beneficial in controlling HSV disease while also reducing HSV-mediated promotion of HIV replication. Antiretroviral therapy leads to a gradual recovery of HSV-specific T-cell responses and a reduction in HSV-related morbidity, indicating that successful management of coinfection should target both HIV and HSV replication. The aim of this review is to address the more speculative issues surrounding the management of HSV/HIV coinfection and to summarize the data that inform them.

Abstract
Genital herpes simplex virus type 2 (HSV2) is highly prevalent worldwide and an increasingly important cause of genital ulcer disease (GUD). Continued HSV2 transmission is facilitated by the large number of undiagnosed cases, the frequency of atypical disease and the occurrence of asymptomatic shedding. The lack of easy, affordable diagnostic methods and specific antiviral treatment in countries with low and middle income is of great concern, given the ability of GUD to enhance HIV transmission and acquisition. With rising HSV2 prevalence contributing to an increase in the proportion of GUD attributed to genital herpes in high-HIV prevalence settings, a safe and effective HSV vaccine is urgently needed. Meanwhile, multifaceted interventions are required to improve recognition of genital herpes, to prevent its spread and also to prevent its potential to promote HIV transmission in developing countries.

Abstract
Eczema herpeticum is an acute, disseminated herpes simplex virus infection which remains a feared complication of eczematous skin diseases, especially atopic dermatitis. The vesicular and erosive clinical picture is often accompanied by systemic signs and symptoms. Why some atopic patients experience multiple attacks of eczema herpeticum and others never have the disorder remains a mystery. Patients with severe or untreated atopic dermatitis are more likely to be affected. The pathogenesis appears to involve a complex interplay of factors, including demasking of binding sites for the virus through the dermatitis, failure to up-regulate antiviral proteins and a lack of plasmacytoid dendritic cells. Treatment of choice is systemic acyclovir therapy.

Abstract
The episodic and daily suppressive treatment of genital herpes is safe and effective with the currently available antiviral agents: acyclovir, valacyclovir and famciclovir. Clinical strategies for the comprehensive management of genital herpes simplex virus infections are recommended. Data from recent clinical trials demonstrating the efficacy of shorter duration of therapy for recurrences and the use of antivirals for the prevention of transmission are reviewed in this article. The factors influencing the choice of therapy, such as cost, ease of dosing and acyclovir resistance are also discussed.

Abstract
OBJECTIVE The objective of this study was to determine herpes simplex virus type 2 (HSV-2) seroprevalence at HIV-1 diagnosis and seroincidence > or =1 year after HIV-1 diagnosis. METHODS HSV type-specific antibodies were detected by enzyme immunoassay. RESULTS The cohort comprised 850 adults diagnosed HIV-positive in 1986-2001 and followed for a median of 3 years. HSV-2 seroprevalence was 63% (95% confidence interval [CI], 60-66%) and was associated with female gender, heterosexual risk group, black ethnicity, and older age. HSV-2 seroincidence was 1.8 per 100 person-years (95% CI, 0.8-2.8) and was associated with other sexually transmitted diseases, including human papilloma virus infection (P = 0.005) and gonorrhea (P = 0.05). A diagnosis of genital herpes was made in 21% HSV-2-seropositive persons and was more likely in those who tested HIV-positive before 1997 (adjusted odds ratio, 5.11; 95% CI, 3.28-7.98; P = 0.0001). CONCLUSIONS Results confirm the epidemiologic association between HIV-1 and HSV-2. HSV-2 seroconversion was a marker of high-risk sexual behavior. The likelihood of developing symptoms of genital herpes declined from 1997 onward.

Abstract
OBJECTIVE To investigate the provision of diagnostic services for genital herpes simplex virus (HSV) infection in the United Kingdom. METHODS National survey of laboratories providing diagnostic services for genital herpes. RESULTS Completed questionnaires were returned from 25/32 (78%) laboratories participating in the Clinical Virology Network, including seven in London, 12 in the rest of England, one in Wales, four in Scotland, and one in Northern Ireland. Virus culture was the diagnostic method of choice in 20/25 (80%) laboratories; 5/25 (20%) routinely used HSV DNA detection by polymerase chain reaction (PCR). HSV PCR for DNA detection in cerebrospinal fluid (CSF) was available in 17/25 (68%) laboratories. Typing of isolates (HSV-1 or HSV-2) was performed routinely in 22/25 (88%) laboratories. Only 2/25 (8%) laboratories offered HSV type specific serology, although an additional 12/25 (48%) referred requests elsewhere. Consistent with this finding, the number of HSV type specific antibody tests referred to the Health Protection Agency increased by nearly fivefold between 1997 and 2003. CONCLUSIONS Virus culture remains the preferred diagnostic method for genital herpes, despite evidence indicating that its sensitivity is suboptimal compared to PCR. As HSV PCR is widely available for testing of CSF, it is recommended that clinicians and virologists discuss ways to implement PCR testing of genital swabs, thus enabling greater diagnostic accuracy. A call is made for studies to assess the use of HSV type specific serology in genitourinary medicine (GUM) settings, now that rapid and validated assays have become available and guidelines have been issues to provide recommendations on their use.

Abstract
Background Herpes Simplex Virus (HSV) Genital Ulcer Disease (GUD) is an important public health problem, whose interaction with HIV results in mutually enhancing epidemics. Conventional methods for detecting HSV tend to be slow and insensitive. We designed a rapid PCR-based assay to quantify and type HSV in cervicovaginal lavage (CVL) fluid of subjects attending a Genito-Urinary Medicine (GUM) clinic. Vaginal swabs, CVL fluid and venous blood were collected. Quantitative detection of HSV was conducted using real time PCR with HSV specific primers and SYBR Green I. Fluorogenic TaqMan Minor Groove Binder (MGB) probes designed around a single base mismatch in the HSV DNA polymerase I gene were used to type HSV in a separate reaction. The Kalon test was used to detect anti-HSV-2 IgG antibodies in serum. Testing for HIV, other Sexually Transmitted Infections (STI) and related infections was based on standard clinical and laboratory methods. Results Seventy consecutive GUM clinic attendees were studied. Twenty-seven subjects (39%) had detectable HSV DNA in CVL fluid; HSV-2 alone was detected in 19 (70%) subjects, HSV-1 alone was detected in 4 (15%) subjects and both HSV types were detected in 4 (15%) subjects. Eleven out of 27 subjects (41%) with anti-HSV-2 IgG had detectable HSV-2 DNA in CVL fluid. Seven subjects (10%) were HIV-positive. Three of seven (43%) HIV-infected subjects and two of five subjects with GUD (40%) were secreting HSV-2. None of the subjects in whom HSV-1 was detected had GUD. Conclusion Quantitative real-time PCR and Taqman MGB probes specific for HSV-1 or -2 were used to develop an assay for quantification and typing of HSV. The majority of subjects in which HSV was detected had low levels of CVL fluid HSV, with no detectable HSV-2 antibodies and were asymptomatic.
