Inamdar DP, Kulkarni A, Basavaraju A. Genital ulcer disease: Study of factors associated and utility of rapid diagnostic methods in current pandemic. J Family Med Prim Care 2024; 13:1473-1480. [PMID: 38827702 PMCID: PMC11141987 DOI: 10.4103/jfmpc.jfmpc_1729_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/20/2023] [Accepted: 12/21/2023] [Indexed: 06/04/2024] Open
Abstract
Background Genital ulcer disease (GUD) is regarded as the most difficult conundrum for clinicians, as valid and rapid methods to diagnose them are limited, especially in India. The sexual behavior of an individual plays a role in the causation of GUD, and it depends on psychological, behavioral, and social well-being, which was significantly affected during the COVID-19 pandemic. Hence, the present study was undertaken to determine the etiology of genital ulcers by using simple, rapid microbiological methods and to study various factors associated with them. Materials and Methods Various rapid tests like staining (Giemsa, Gram, and Diff Quick) and serology for antibody detection were used to diagnose agents causing genital ulcers among 71 suspected patients during the study period of 1 year. After due informed consent, sociodemographic and behavioral factors were recorded in proforma and analyzed. Results Rapid tests could aid in diagnosing 47.9% of cases of GUD. Turnaround time was less than 60 minutes for all tests carried out. Genital herpes was the most common GUD followed by syphilis. Male gender (74.6%), age group of more than 34 years old (62%), literate (71.8%), and earning (70.4%) constituted most of the population presenting with GUD. Behavioral factors like promiscuity with a known person (83.1%) had a significant association (P 0.04) with GUD. Conclusion Rapid diagnostic tests could assist in the early treatment of GUD cases. Factors like literacy, financial independence, and promiscuity with known individuals were associated with GUD in our study during the COVID-19 pandemic.

Korean sexually transmitted infection guidelines 2023 revision, guideline update of viral infections: Genital herpes and anogenital warts. Investig Clin Urol 2024; 65:9-15. [PMID: 38197746 PMCID: PMC10789539 DOI: 10.4111/icu.20230275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/15/2023] [Accepted: 11/06/2023] [Indexed: 01/11/2024] Open
Abstract
The Korean Association of Urogenital Tract Infection and Inflammation and the Korea Disease Control and Prevention Agency regularly update, revise, and develop new content for the Korean sexually transmitted infection (STI) guidelines. These professional bodies respond to changing epidemiological trends and evolving scientific evidence, and consider advances in laboratory diagnostics and research. The principal recommendations of the 2023 Korean STI guidelines in terms of viral infection follow: 1) If genital herpes recurs more than 4-6 times annually, suppressive therapy with acyclovir 400 mg orally 2 times/day or famciclovir 250 mg orally 2 times/day or valacyclovir 500 mg orally once a day (for patients with <10 episodes/year) or valacyclovir 1 g orally once daily (for patients with ≥10 episodes/year) is recommended to prevent recurrence; 2) molecular human papillomavirus (HPV) testing is not recommended as a routine test for STI status, nor for determination of HPV vaccination status; and 3) patients should inform their current sexual partners about anogenital warts because the types of HPV that cause such warts can be passed to partners. These guidelines will be updated every 5 years and will be revised when new knowledge on STIs becomes available and there is a reasonable need to improve the guidelines. Physicians and other healthcare providers can use the guidelines to assist in the prevention and treatment of STIs.

Abstract
Genital herpes, primarily caused by herpes simplex virus-2 (HSV-2), remains a pressing global health concern. Its remarkable ability to intertwine with cellular processes, from harnessing host machinery for replication to subverting antiviral defenses like autophagy and programmed cell death, exemplifies the intricate interplay at the heart of its pathogenesis. While the biomedical community has extensively researched antiviral interventions, the efficiency of these strategies in managing HSV-2 remains suboptimal. Recognizing this, attention has shifted toward leveraging host cellular components to regulate HSV-2 replication and influence the cell cycle. Furthermore, innovative interventional strategies-including drug repurposing, microbivacs, connecting the host microbiome, and exploiting natural secondary metabolites-are emerging as potential game changers. This review summarizes the key steps in HSV-2 pathogenesis and newly discovered cellular interactions, presenting the latest developments in the field, highlighting existing challenges, and offering a fresh perspective on HSV-2's pathogenesis and the potential avenues for its treatment by targeting cellular proteins and pathways.

Abstract
Herpes simplex virus type 2 (HSV-2) infection, which is almost exclusively sexually transmitted, causes genital herpes. Although this lifelong and incurable infection is extremely widespread, currently there is no readily available diagnostic device that accurately detects HSV-2 antigens to a satisfactory degree. Here, we report an ultrasensitive electrochemical device that detects HSV-2 antigens within 9 min and costs just $1 (USD) to manufacture. The electrochemical biosensor is biofunctionalized with the human cellular receptor nectin-1 and detects the glycoprotein gD2, which is present within the HSV-2 viral envelope. The performance of the device is tested in a guinea pig model that mimics human biofluids, yielding 88.9% sensitivity, 100.0% specificity, and 95.0% accuracy under these conditions, with a limit of detection of 0.019 fg mL-1 for gD2 protein and 0.057 PFU mL-1 for titered viral samples. Importantly, no cross-reactions with other viruses were detected, indicating the adequate robustness and selectivity of the sensor. Our low-cost technology could facilitate more frequent testing for HSV-2.

Abstract
Herpes simplex virus (HSV) belongs to the Herpesviridae family and is divided into two subtypes: HSV-1 and HSV-2. It is known that herpesviruses lie dormant in neural ganglion cells and are reactivated during times of stress, trauma, fever, and immunosuppression. While HSV primarily causes mucosal infections such as cold sores or upper respiratory tract manifestations, it can also lead to serious, life-threatening infections, particularly in immunocompromised patients. Although HSV is occasionally detected in airway samples from critically ill patients, true HSV pneumonia is rare. HSV pneumonia is thought to result from the aspiration of salivary secretions that can travel from the pharynx and tracheobronchial areas to the lungs. It can be difficult to diagnose, and the presence of HSV in respiratory specimens does not necessarily indicate true infection. Treatment with antiviral drugs such as acyclovir should be considered based on the clinical presentation, corroborative findings, and the presence of cytopathological changes in the bronchoalveolar specimen. The prognosis of HSV pneumonia is generally poor and early detection is critical for better outcomes. This review discusses the risk factors, clinical presentation, diagnosis, treatment, and prognosis of HSV pneumonia and emphasizes the importance of distinguishing between true infection and carrier status.

Abstract
Background: Herpes simplex virus (HSV) is a neurotropic DNA virus with a high prevalence. Following primary infection, HSV remains dormant in the neural ganglia. Secondary infection can emerge after the reactivation of latent infection, presenting as neurological manifestations. Previous studies have demonstrated the relationship between HSV reactivation and selective involvement of cranial nerves. Depending on the affected nerve, cranial mononeuropathies can present with symptoms, including diplopia, blurred vision, vertigo, unilateral facial palsy, speech impairment, swallowing difficulties, and hoarseness. Objectives: This study used a serological assay to compare HSV reactivation frequency between patients with recent idiopathic cranial mononeuropathies and normal individuals. Methods: Plasma samples from 35 idiopathic cranial mononeuropathy cases (57.2% women, mean age 58.37 years) and 35 age and sex-matched healthy controls were analyzed for anti-HSV immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies by enzyme-linked immunosorbent assay (ELISA). Results: Anti-HSV IgG antibody was positive in 91.4% of patients and 88.6% of controls. The mean serum anti-HSV IgG antibody level was significantly higher in patients (146.78 ± 60 RU/mL) than in the controls (130.61 ± 52.99 RU/mL) (P-value = 0.037). Anti-HSV IgM antibody was positive in 37.1% of patients and 14.3% of controls (P = 0.042). Conclusions: The frequency of HSV reactivation was significantly higher in patients with acute idiopathic cranial mononeuropathy than in the healthy controls, indicating the possible role of HSV as an etiology of cranial mononeuropathy.

Abstract
The herpes virus was named by the Greek physician Hippocrates who called it herpes because the lesions appeared near each other and were vesicular. Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae are subfamilies of the human herpes virus family. The Alphaherpesvirinae subfamily includes the simplex viruses-HSV-1 and HSV-2-and varicellovirus-varicella zoster virus. There are more than 200 members of the Herpesviridae family capable of infecting different species, 8 of which are known to cause disease in humans. The simplex viruses can cause lifelong genital infections, and despite the prevalence of HSV-1 and HSV-2 infections in the United States decreasing in the past 20 years, infections with these viruses continue to contribute to significant clinical and psychological morbidities.

Abstract
Herpes simplex virus (HSV) usually produces cytopathic effect (CPE) within 24-72 h post-infection (P.I.). Clinical isolates from recurrent HSV infections in patients on Acyclovir therapy were collected between 2016 and 2019 and tested in cell cultures for cytopathic effects and further in-depth characterization. Fourteen such isolates did not show any CPE in A549 or Vero cell lines even at 120 h P.I. However, these cultures remained positive for HSV-DNA after several passages. Sequence analysis revealed that the non-CPE isolates were all HSV-1. Analysis of the thymidine kinase gene from the isolates revealed several previously reported and two novel ACV-resistant mutations. Immunofluorescence and Western blot data revealed a low-level expression of the immediate early protein, ICP4. Late proteins like ICP5 or capsid protein, VP16 were almost undetectable in these isolates. AFM imaging revealed that the non-CPE viruses had structural deformities compared to wild-type HSV-1. Our findings suggest that these strains are manifesting an unusual phenomenon of being non-CPE herpesviruses with low level of virus protein expressions over several passages. Probably these HSV-1 isolates are evolving towards a more "cryptic" form to establish chronic infection in the host thereby unraveling yet another strategy of herpesviruses to evade the host immune system.

Abstract
Compounds based on cerium are highly promising objects in biotechnology regarding their high biological activities such as antiviral, antibacterial, antifungal, neuro- and radioprotective action, and antioxidant activity. On their basis is possible to develop compositions capable of activating the systems of cellular and humoral immune defence and use them for the prevention and therapy of viral diseases, which makes it achievable to use them for the development of potential antiherpetic agents. Despite the success of their application in biotechnological fields, the mechanism of their action on biological objects requires detailed research. The work aimed to verify in vitro anti-HSV-1/2 activity of trivalent and tetravalent cerium salts (1 mM – 0.01 nM) according to the preventive and therapeutic regimen. Methods: virological, cytological, statistical. Results. The therapeutic regime was noneffective. In the preventive regime, salt (NH4)2Ce(NO3)6 in vitro forms antiviral resistance in the range of investigated concentrations, while the salt CeCl3·7Н2О forms a non-linear, sinusoidal-like concentration-dependent anti-HSV-1/2 response of cells. Conclusions. Cerium salts (III and IV) can cause the formation of a state of antiviral resistance in the model system MA-104 - HSV-1/2 during their previous 24 h of contact with test cells. Cerium salt (IV) provides 50% inhibition of the cytopathic action of HSV-1/2 at a concentration of 1 μM. It is assumed that the shown antiviral activity of cerium salts may be due to their effect on the interferon system and the formation of antiviral resistance in cells.

Abstract
Introduction Herpes simplex virus (HSV) Type 2 primarily causes genital herpes, while HSV Type 1 is responsible for oral and facial lesions. The objective of this study was to isolate and characterize HSV from herpetic lesions among human immunodeficiency virus (HIV) infected patients and to evaluate their acyclovir susceptibility pattern. Materials and Methods Blister fluid and swabs from ulcers were collected from patients with clinical diagnosis of HSV infection among patients attending the HIV clinic of two tertiary care centers - Medical College, Kolkata, and School of Tropical Medicine, Kolkata. These samples were cultured in the Vero cell line. Growth of virus was noted by observing the characteristic cytopathic effect of HSV, which was further confirmed by immunofluorescence and polymerase chain reaction (PCR). These isolates were then subjected to the Vero cells with serial dilutions of acyclovir for determining the susceptibility pattern. Results Among the 52 samples received, 8 (15.38%) showed growth of HSV. After confirmation by immunofluorescence and PCR, all seven isolates from genital samples were identified as HSV-2 and the lone isolate from oral lesion was confirmed as HSV 1. Out of the eight isolates, 25% showed resistance to acyclovir. The overall isolation rate was more from genital blister than genital ulcer which was 46.15% and 2.86%, respectively. Conclusion HSV was isolated in 15.38% of cases of clinical herpes. There was a higher isolation rate of virus from blister fluid as compared to ulcer scrapings. Acyclovir resistance in 25% of cases is alarmingly high.

Abstract
Herpes is a widespread viral infection caused by the herpes simplex virus (HSV) that has no permanent cure to date. There are two subtypes, HSV-1 and HSV-2, that are known to cause a variety of symptoms, ranging from acute to chronic. HSV is highly contagious and can be transmitted via any type of physical contact. Additionally, viral shedding can also happen from asymptomatic infections. Thus, early and accurate detection of HSV is needed to prevent the transmission of this infection. Herpes can be diagnosed in two ways, by either detecting the presence of the virus in lesions or the antibodies in the blood. Different detection techniques are available based on both laboratory and point of care (POC) devices. Laboratory techniques include different biochemical assays, microscopy, and nucleic acid amplification. In contrast, POC techniques include microfluidics-based tests that enable on-spot testing. Here, we aim to review the different diagnostic techniques, both laboratory-based and POC, their limits of detection, sensitivity, and specificity, as well as their advantages and disadvantages.

Abstract
BACKGROUND Herpes simplex virus (HSV) is a highly infectious pathogen that is easily transmitted via the bodily fluids of an infected individual. This virus usually affects individuals older than six months of age, and rarely causes lesions or symptoms in younger patients.
CASE SUMMARY We present the case of a five-month-old healthy girl who presented with painful herpetic gingivostomatitis and perioral vesicles. We discuss the pathophysiology of primary HSV infection and the effect of maternal antibodies on the infant’s immune system. In addition, we explain the diagnosis, management, and prognosis of HSV infection in young infants.
CONCLUSION This case highlights the importance of early diagnosis and management of HSV infections to decrease the risk of developing severe complications and death.

Abstract
INTRODUCTION Febrile neutropenia represents one of the most common treatment-associated complications in the management of acute myeloid leukemia (AML) and is considered an oncologic emergency. Rapid and detailed workup as well as the initiation of empiric broad-spectrum antibiotic therapy are critical to avoid sepsis and to reduce mortality. Although a definitive source of infection is frequently not identified, the severely immunosuppressed status of the AML patient undergoing cytotoxic therapy results in a high risk for a wide array of bacterial, fungal, and viral etiologies. AREAS COVERED The authors herein review the diagnostic and therapeutic approach to the neutropenic leukemia patient based on the current knowledge. Special consideration is given to the rapidly changing therapeutic landscape in AML, creating new challenges in the management of infectious complications. EXPERT OPINION Multidrug-resistant organisms pose a major challenge in the management of neutropenic fever patients with hematologic malignancies - including AML. Future directions to improve outcomes demand innovative treatment approaches as well as advances in biomarker research to facilitate diagnosis and disease monitoring. Recent achievements in AML-targeted therapy led to an increased incidence of differentiation syndrome, a potentially life-threatening side effect that frequently resembles clinical infection and requires prompt recognition and aggressive intervention.

Abstract
Treatment of cancer is a major challenge even though the pathophysiology is becoming clearer with time. A number of new chemical entities are developed to target cancer growth inhibition, but the targeted delivery of these products still needs novel research. This is of utmost importance not only for higher efficacy but also for a reduction in systemic toxicity and cost of treatment. Although multiple novel targets and molecules are being researched, most of them could not pass the regulatory approval process, due to low benefit-risk ratio and lack of target specificity. Failure of a majority of these drugs was in part due to their superiority claimed via surrogate markers. Despite these, currently, more than 100 chemotherapeutic agents are in practice. This review paper discusses in detail the molecular basis, drug discovery, and pros and cons over conventional treatment approaches of three novel approaches in cancer therapy, i.e., (i) antibody-drug conjugates, (ii) cancer immunotherapy, and (iii) metronomic chemotherapy. All the drugs developed using these three novel approaches were compared against the established treatment regimens in clinical trials with clinical end points, such as overall survival, progression-free survival, and quality of life.

Abstract
Infection of Herpes Simplex Virus type 2 (HSV-2) is a lifelong sexually transmitted disease. According to the Center for Disease Control and Prevention (CDC), 11.9% of the United States (U.S.) population was infected with HSV-2 in 2015-2016. The HSV-2 pathogen establishes latent infections in neural cells and can reactivate causing lesions later in life, a strategy that increases pathogenicity and allows the virus to evade the immune system. HSV-2 infections are currently treated by Acyclovir only in the non-constitutional stage, marked by genital skin lesions and ulcers. However, patients in the constitutional stage expressing mild and common (with other diseases) symptoms, such as fever, itching and painful urination, remain difficult to detect and are untreated. In this study, we develop and analyze a mathematical model to study the transmission and control of HSV-2 among the U.S. population between the ages of 15-49 when there are options to treat individuals in different stages of their pathogenicity. In particular, the goals of this work are to study the effect on HSV-2 transmission dynamics and to evaluate and compare the cost-effectiveness of treating HSV-2 infections in both constitutional and non-constitutional stages (new strategy) against the current conventional treatment protocol for treating patients in the non-constitutional stage (current strategy). Our results distinguish model parameter regimes where each of the two treatment strategies can optimize the available resources and consequently gives the long-term reduced cost associated with each treatment and incidence. Moreover, we estimated that the public health cost of HSV-2 with the proposed most cost-effective treatment strategy would increase by approximately 1.63% in 4 years of implementation. However, in the same duration, early treatment via the new strategy will reduce HSV-2 incidence by 42.76% yearly and the reproduction number will decrease to 0.84 from its current estimate of 2.5. Thus, the proposed new strategy will be significantly cost-effective in controlling the transmission of HSV-2 if the strategy is properly implemented.

Abstract
Background Rapid identification of human herpesviruses from lesion swabs is necessary for timely initiation of antiviral treatment, especially with infections involving neonates and immunocompromised individuals. The aim of the study was to investigate the results of an in-house polymerase chain reaction (PCR) test for herpesviruses in patients with symptoms suggestive for a herpesvirus infection. Patients and methods In this single center retrospective study the results of 3677 lesion swab specimens tested for human herpes simplex virus 1 and 2 (HSV 1 and 2) and varicella zoster virus (VZV) were analyzed in the context of data sheets giving details of the suspected diagnosis, medical history as well as the demographic data of the patients. The PCR procedures for cytomegalovirus (CMV), Epstein-Barr virus (EBV) and human herpes virus 8 (HHV-8) were applied on special occasions. Results Of the samples 3369 (91.6%) were swabs and a minority were tissue or blood samples. Of the 3015 samples tested for HSV‑1, HSV‑2 and VZV concomitantly, 52.3% were positive for at least one of these viruses. Clinically distinct conditions, such as herpes zoster and varicella had a high rate of positive PCR results, ranging from 81% to 88%, respectively. Among HSV‑2 positive samples, 23.7% derived from human immunodeficiency virus (HIV) positive patients, in contrast to the 10.8% originating from immunocompetent patients, the difference being statistically significant (p < 0.002). The HSV‑2 was detected more often in women than in men. Conclusion Distinct clinical diagnoses have a high correlation rate with positive PCR results. A significantly higher number of HSV‑2 positive results were found in HIV positive patients and in women.

Abstract
There is a growing need to screen multiple infections simultaneously rather than diagnosis of one pathogen at a time in order to improve the quality of healthcare while saving initial screening time and reduce costs. This is the first demonstration of a five-step protein array assay for the multiplexed detection of HIV, HPV and HSV antibodies on an integrated microfluidic system. HIV, HPV and HSV reactive antibodies from both serum and saliva were rapidly detected by acoustic streaming-based mixing and pumping to enable an integrated, rapid and simple-to-use multiplexed assay device. We validated this device with 37 serum and saliva samples to verify reactivity of patient antibodies with HIV, HPV and HSV antigens. Our technology can be adapted with different protein microarrays to detect a variety of other infections, thus demonstrating a powerful platform to detect multiple putative protein biomarkers for rapid detection of infectious diseases. This integrated microfluidic protein array platform is the basis of a potent strategy to delay progression of primary infection, reduce the risk of co-infections and prevent onward transmission of infections by point-of-care detection of multiple pathogens in both serum and oral fluids.

Abstract
Herpes simplex virus type 1 and type 2 (HSV-1 & HSV-2) are one of the leading causes of ulcer and blister lesions worldwide. These infections are latent with recurrences but many people may have a seropositive antibody yet remain asymptomatic. Although HSV presenting with hypertrophic lesions have been reported in the literature at urogenital, lung, and conjunctival sites, we describe a case of a mass lesion in the nasal cavity of a 46 year-old female with a history of human immunodeficiency virus (HIV). The patient presented initially with nasal congestion and subsequently developed facial edema. The mass lesion regressed after one month of treatment with valacyclovir.

Abstract
Herpes Simplex Virus (HSV) hepatitis in liver transplant patients is a rarely reported infective complication of HSV with severe consequences, often leading to fulminant hepatitis if left untreated. The clinical signs are often atypical, leading to under-reporting in the literature and potential delays in treatment. Our case report describes such atypical mucocutaneous lesions in a liver transplant recipient. We highlight the need for further reports, especially those with images, in order to aid the diagnosis of HSV infection, and to allow prompt treatment to prevent complications such as HSV hepatitis.

Abstract
Background Human herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are responsible for a plethora of human diseases, of which cutaneous and mucocutaneous infections are the most prevalent. In its most severe form, HSV infection can cause meningitis/encephalitis. We compared the Luminex ARIES HSV 1&2 assay (Luminex Corp., Austin, TX, USA), an automated sample-to-result molecular solution, to two non-automated HSV DNA assays. Methods A total of 116 artificial controls were used to determine the analytical performance of the ARIES assay. Controls were prepared by spiking universal transport medium (UTM) and cerebrospinal fluid (CSF) samples from patients who tested negative for HSV by an in-house HSV-1 and -2 DNA assay with reference materials (SeraCare Life Sciences, MA, USA; ZeptoMetrix Corp., MA, USA). Another 117 clinical samples were then used to compare the clinical performance of the ARIES assay with those of an in-house assay and the FTD Neuro 9 assay (Fast Track Diagnostics, Junglinster, Luxembourg). Results The analytical sensitivity (95% limit of detection) of the ARIES assay was 318 copies/mL (UTM samples) and 935 copies/mL (CSF samples) for HSV-1 strain 96 and 253 copies/mL (UTM samples) and 821 copies/mL (CSF samples) for HSV-2 strain 09. No cross-reactivity was observed in samples spiked with 14 non-HSV microorganisms. Compared with the reference result (agreement between the in-house and FTD Neuro 9 results), the ARIES assay had overall concordance rates of 98.2% (111/113) and 100% (113/113) for HSV-1 and HSV-2, respectively. Conclusions The ARIES assay appears to be an excellent alternative for rapid detection and differentiation of HSV in skin and genital infections, meningitis, and encephalitis.

Abstract
BACKGROUND This article provides an update on the incidence of neonatal herpes, guideline adherence by health care professionals (HCP) and trends in genital herpes simplex virus (HSV) infection during pregnancy in the Netherlands. METHODS Questionnaires were sent to all hospitals inquiring about numbers and characteristics of neonatal and maternal HSV infections, and guideline adherence between 2012 and 2015. Longitudinal trends were investigated from 1999 onward using survey data and Perinatal Registry of the Netherlands data (Perined). Trends were smoothed with Poisson regression splines. Risk indicators for neonatal and maternal HSV infections were examined with Poisson regression analyses. RESULTS Neonatal herpes incidence was 4.8/100,000 live births based on survey data (2012-2015) and 3.4/100,000 based on Perined (2012-2014). Mortality rate was 23% (7/30). Neonatal herpes incidence increased slightly over time as did the prevalence of genital HSV infection among pregnant women. Non-Western ethnicity (Rate Ratio: 1.9; 95% confidence interval: 1.5-2.5) and age <20 years (Rate Ratio: 2.3; 95% confidence interval: 1.2-4.7) were associated with genital herpes during pregnancy. In Perined, none of the neonatal herpes cases had a mother diagnosed with an active genital herpes infection during pregnancy. Preventive measures to reduce vertical herpes transmission (such as cesarean section) were less commonly reported by HCP in 2012-2015 compared with 2006-2011. CONCLUSIONS Neonatal herpes incidence in the Netherlands slowly increased over the last 15 years. An increased genital HSV prevalence during pregnancy or, to lower extent, the decreased guideline adherence by HCP may be responsible. A rise in asymptomatic maternal HSV shedding is also plausible, emphasizing the challenges in preventing neonatal herpes.

Abstract
A middle-aged man with decompensated cirrhosis and a dimorphic multisite skin rash is diagnosed with rare atypical herpes simplex infection, manifesting Sweet's syndrome (SS) in the absence of other described associations. SS, an acute febrile neutrophilic dermatosis, has three common forms-classical or idiopathic, malignancy associated and drug induced. Systemic autoimmune, connective tissue diseases and infections are also strong associations. The latter is commonly described in Gram-positive bacteria, salmonellosis and Yersinia Herpes infections are a rare cause of SS, reported only thrice in literature, one with concomitant lupus, the second with associated mycobacterial infection and third, in metastatic breast disease in contrast to our patient. Atypical rash, especially if dimorphic, warrants histopathological evaluation to confirm underlying disease.

Abstract
We are reporting the first case of lymphogranuloma venereum in women in East-Central Europe. A 22-year-old heterosexual woman attended our department of venereology. She complained about a burning sensation in the urethra and vaginal discharge. Many tests were performed, and lymphogranuloma venereum, syphilis, gonorrhea, chlamydial urethritis and cervicitis, genital herpes, genital warts, and hepatitis C were diagnosed. Lymphogranuloma venereum was originally endemic in tropical and subtropical areas, but since 2003, outbreaks of this infection have been reported in North America, Europe, and Australia in men who have sex with men (MSM) community. To date, all cases of lymphogranuloma venereum in the Czech Republic appeared in men, predominantly in HIV-positive MSM. There are not many evidences about lymphogranuloma venereum (LGV) in women in developed countries. This report underlines the need for awareness of lymphogranuloma venereum in women among gynecologists, venereologists, and other physicians not only in Western Europe, but across all European countries.

Abstract
BACKGROUND Sexually transmitted infections (STIs) are spread primarily through sexual contact and are a major cause of morbidity and mortality worldwide. Once identified, some STIs can be cured following appropriate therapy; for others, suppressive regimens and approaches to prevent ongoing transmission are important. The incidence of many common STIs is increasing in the US as well as worldwide, and hundreds of millions of people are currently infected. Laboratory testing plays a major role in the diagnosis and treatment of STIs, and clinical laboratorians should be familiar with the current guidelines and methods for testing. CONTENT Accurate and sensitive methods to diagnose STIs are essential to direct appropriate antimicrobial therapy and interrupt the cycle of disease transmission. This review summarizes laboratory testing for common bacterial, viral, and parasitic causes of STIs. Disease manifestations reviewed include cervicitis and urethritis, genital ulcerative disease, human immunodeficiency virus, viral hepatitis, human papilloma virus, and vaginitis. Recent advancements in the recognition and management of STIs, including updates to diagnostic algorithms, advances in testing methods, and emerging challenges with antimicrobial resistance, are summarized. SUMMARY Diagnostic methods and therapeutic guidelines for STIs are rapidly evolving. In combination with changing epidemiology, the development of novel therapeutics, and advancements in diagnostic methods, this has resulted in changing practices in laboratory testing and, subsequently, management of disease. Molecular methods have facilitated personalized therapy and follow-up regimens targeted for individual types or strains of some STIs.

Abstract
Herpes simplex virus (HSV) primary infection and reactivation has been associated with the inflammation and transient decrease in immunocompetence after surgery and local trauma. In addition, HSV infection is known to impair wound healing, increase risk of scarring, and impede connective tissue graft transplantation. To our knowledge, this is the first case of HSV infection complicating cleft palate repair presented in literature. In this report, we present a case of primary HSV infection occurring in a healthy 26-month-old patient after repair of the secondary cleft palate with mucoperichondrial flaps and V-Y pushback. The patient developed high fever on postoperative day 1, which was followed by perioral vesicular lesions and multiple intraoral ulcerations involving the lips, palate, and posterior pharynx. Unknown to the surgeons, the patient was exposed to HSV before surgery by a sibling with orolabial HSV infection. The infective cause was ascertained via polymerase chain reaction for HSV-1 DNA, and the infection was treated with topical and intravenous acyclovir for 1 week. The patient recovered well with adequate flap healing, good aesthetic outcome, and no complications on 1-month follow-up. This report underscores the importance of prompt recognition of herpetic infections in the patient with craniofacial surgery and reviews the association and complications of HSV infection in surgical healing. Early identification with prompt antiviral therapy and meticulous wound care are essential to ameliorate the scarring and delayed wound healing associated with HSV infection.

Abstract
BACKGROUND Miscarriage is the spontaneous loss of a pregnancy before 12 weeks (early miscarriage) or from 12 to 24 weeks (late miscarriage) of gestation. Miscarriage occurs in one in five pregnancies and can have considerable physiological and psychological implications for the patient. It is also associated with significant health care costs. There is evidence that potentially preventable infections may account for up to 15% of early miscarriages and up to 66% of late miscarriages. However, the provision of associated screening and management algorithms is inconsistent for newly pregnant women. Here, we review recent population-based studies on infections that have been shown to be associated with miscarriage. METHODS Our aim was to examine where the current scientific focus lies with regards to the role of infection in miscarriage. Papers dating from June 2009 with key words 'miscarriage' and 'infection' or 'infections' were identified in PubMed (292 and 327 papers, respectively, on 2 June 2014). Relevant human studies (meta-analyses, case-control studies, cohort studies or case series) were included. Single case reports were excluded. The studies were scored based on the Newcastle - Ottawa Quality Assessment Scale. RESULTS The association of systemic infections with malaria, brucellosis, cytomegalovirus and human immunodeficiency virus, dengue fever, influenza virus and of vaginal infection with bacterial vaginosis, with increased risk of miscarriage has been demonstrated. Q fever, adeno-associated virus, Bocavirus, Hepatitis C and Mycoplasma genitalium infections do not appear to affect pregnancy outcome. The effects of Chlamydia trachomatis, Toxoplasma gondii, human papillomavirus, herpes simplex virus, parvovirus B19, Hepatitis B and polyomavirus BK infections remain controversial, as some studies indicate increased miscarriage risk and others show no increased risk. The latest data on rubella and syphilis indicate increased antenatal screening worldwide and a decrease in the frequency of their reported associations with pregnancy failure. Though various pathogens have been associated with miscarriage, the mechanism(s) of infection-induced miscarriage are not yet fully elucidated. CONCLUSIONS Further research is required to clarify whether certain infections do increase miscarriage risk and whether screening of newly pregnant women for treatable infections would improve reproductive outcomes.

Abstract
High titers of infectious viruses for vaccine and diagnostic reference panel development are made by infecting susceptible mammalian cells. Laboratory procedures are strictly performed in a Bio-Safety Level-3 (BSL3) laboratory and each entry and exit involves the use of disposable Personnel Protective Equipment (PPE) to observe cell culture conditions. Routine PPE use involves significant recurring costs. Alternative non-invasive optical sensor based approaches to remotely monitor cell culture may provide a promising and cost effective approach to monitor infectious virus cultures resulting in lower disruption and costs. We report here the monitoring of high titer cultures of Human Immunodeficiency Virus-1 (HIV-1) and Herpes Simplex Virus-2 (HSV-2) remotely with the use of optical oxygen sensors aseptically placed inside the cell culture vessel. The replacement of culture media for cell and virus propagation and virus load monitoring was effectively performed using this fluorescent sensor and resulted in half the number of visits to the BSL3 lab (five versus ten).

Abstract
Background: PCR is a molecular technique for herpes simplex virus (HSV) detection that can cause life-threatening infections such as encephalitis and keratitis. However, the main issues, false-negative results causing by PCR inhibitors, of this technique that reduce PCR efficiency. To overcome this problem, a competitive internal amplification control (IAC) was constructed for conventional PCR using the PCR-cloning technique. Objectives: The purpose of this study is the design of competitive IAC for PCR diagnosis of HSV, which in fact is the main cause of keratitis and viral encephalitis in developed countries. Materials and Methods: Composite primers for PCR amplification of Leishmania major kDNA (kinetoplast DNA) were designed and optimized to use as IAC-HSV. IAC-HSV amplified in a non-stringent condition, ligated into pTZ57R plasmid vector, and transformed into Escherichia coli JM207 and then cloned. Resulting IAC was used for 105 CSF and 78 keratitis specimens. Results: PCR amplicons for HSV and IAC-HSV were 454-bp and 662-bp, respectively. Detection limit of IAC was determined as 1000 plasmids per PCR reaction. IAC sensitivity for HSV detection was determined as 1000 plasmids per PCR reaction. IAC sensitivity for HSV detection was 500 copies/mL of HSV DNA. Among all specimens, 7 inhibited specimens were detected. Conclusions: Indeed, using other DNA as an IAC is expected to detect false-negative results and amplification of the DNA is the key tool to examine the accuracy of amplification and detection steps. This internal amplification control is applicable for early reliable diagnosis of HSV in different loads of virus in different specimens.

Abstract
Sexually transmitted infections (STIs) are a public health problem, and their prevalence is rising even in developed nations, in the era of HIV/AIDS. While the consequences of STIs can be serious, the good news is that many of these complications are preventable if appropriate screening is done in high-risk individuals, when infection is strongly suspected. The diagnostic tests for STIs serve many purposes. Apart from aiding in the diagnosis of typical cases, they help diagnose atypical cases, asymptomatic infections and also multiple infections. But, the test methods used must fulfill the criteria of accuracy, affordability, accessibility, efficiency, sensitivity, specificity and ease of handling. The results must be rapid, cost-effective and reliable. Most importantly, they have to be less dependent on collection techniques. The existing diagnostic methods for STIs are fraught with several challenges, including delay in results, lack of sensitivity and specificity. With the rise of the machines in diagnostic microbiology, molecular methods offer increased sensitivity, specificity and speed. They are especially useful for microorganisms that cannot be, or are difficult to cultivate. With the newer diagnostic technologies, we are on the verge of a major change in the approach to STI control. When diagnostic methods are faster and results more accurate, they are bound to improve patient care. As automation and standardization increase and human error decreases, more laboratories will adopt molecular testing methods. An overview of these methods is given here, including a note on the point-of-care tests and their usefulness in the era of rapid diagnostic tests.

Abstract
BACKGROUND HSV-2 diagnosis is typically by viral culture, viral DNA amplification of lesion material or by serology in cases of subclinical presentation. These methods can be time consuming and expensive. The Uni-Gold™ HSV-2 Rapid is a fast, point-of-care diagnostic test that can be performed outside a full service laboratory. OBJECTIVE To evaluate the ability of the Uni-Gold™ HSV-2 Rapid to correctly diagnose the presence or absence of anti-HSV-2 antibodies in patient serum samples in comparison to the University of Washington HSV Western blot (UWWB). STUDY DESIGN Sera from 100 adult patients in the USA were tested for HSV-2 specific antibodies by Uni-Gold™ HSV-2 Rapid and results were compared to those of the UWWB to determine the test's sensitivity and specificity. RESULTS Of 18 patients seropositive for HSV-2 by UWWB, 17 were correctly identified as such by the Uni-Gold™ HSV-2 Rapid. Of 76 patients who were seronegative for HSV-2 by UWWB, 75 were correctly identified by the rapid test. Six sera had indeterminate results by UWWB. Sensitivity for the Uni-Gold™ HSV-2 Rapid was 94% and specificity was 99%. CONCLUSION The Uni-Gold™ HSV-2 Rapid had high sensitivity and specificity in a small sample of unselected, adults seeking care in the Seattle, USA area. An accurate, near-person test allows immediate counseling directed toward symptom recognition, treatment, and practices that can limit the risk of HSV-2 transmission.

Abstract
BACKGROUND A rapid point-of-care test with high sensitivity and specificity is required in order to fulfill the need for early detection and screening of Herpes simplex virus type 2 (HSV-2) infection among patients with genital ulcer disease (GUD), for better management and control of virus transmission. METHODS The goal of this study is to evaluate the performance of the commercially available HerpeSelect Express rapid test in comparison with three ELISA assays: HerpeSelect ELISA, Kalon HSV-2 glycoprotein G2 assay, and monoclonal antibody blocking enzyme immunoassay, which was used as the gold standard for the detection of HSV-2 antibodies. RESULTS This study showed high sensitivity (ranging from 82.6 to 100%) and specificity (100%) of the HerpeSelect Express rapid test when compared to the three ELISA assays. The agreement between the HerpeSelect Express rapid test with the three ELISAs ranged from 93.3 to 100%. CONCLUSION The HerpeSelect Express rapid test has adequate sensitivity and specificity for confirming HSV-2 infection in patients with GUD, indicating its suitability for epidemiological studies.

Abstract
We report a challenging case of an atypical presentation of recrudescent herpes simplex virus infection in a patient with common variable immunodeficiency. Oral infections in immunosuppressed patients may present with unusual clinical features that can mimic non-infectious diseases. This report discusses the diagnostic steps necessary for definitive diagnosis and to guide appropriate and effective management.

Abstract
The American Academy of Pediatrics recommends that site-specific cultures be obtained, when indicated, for sexually victimized children. Nucleic acid amplification testing is a highly sensitive and specific methodology for identifying sexually transmitted infections. Nucleic acid amplification tests are also less invasive than culture, and this may provide an efficacious alternative for children suspected of being sexually abused.

Abstract
Accurate identification of persons with genital herpes is necessary for optimal patient management and prevention of transmission. Because of inherent inaccuracies, clinical diagnosis of genital herpes should be confirmed by laboratory testing for the causative agents herpes simplex virus type 1 (HSV-1) and HSV type 2 (HSV-2). Further identification of the HSV type is valuable for counselling on the natural history of infection and risk of transmission. Laboratory methods include antigen detection, culture, polymerase chain reaction (PCR) and conventional and type-specific serology (TSS). PCR has, by far, the greater sensitivity and should be the test of choice for symptomatic cases. HSV-2 TSS is indicated for patients with genital lesions in whom antigen detection, culture or PCR fail to detect HSV, and for patients who are asymptomatic but have a history suggestive of genital herpes. HSV-2 TSS is further indicated for patients infected with HIV. HSV-2 TSS along with HSV-1 TSS may be considered, as appropriate, in evaluating infection and/or immune status in couples discordant for genital herpes, women who develop their first clinical episode of genital herpes during pregnancy, asymptomatic pregnant women whose partners have a history of genital herpes or HIV infection, and women contemplating pregnancy or considering sexual partnership with those with a history of genital herpes. The above should be performed in conjunction with counselling of infected persons and their sex partners.
