Abstract
Abnormal liver function tests during pregnancy are common. While hepatic injury during pregnancy mostly has minimal adverse influence on maternal and fetal outcomes, severe maternal and fetal morbidities, and even death, sometimes occur. Here, we review the epidemiology, clinical features, diagnosis, and management of hepatitis during pregnancy caused by the less common pathogens, including Epstein-Barr virus (EBV), cytomegalovirus (CMV), herpes simplex viruses (HSVs), dengue fever, malaria, leptospirosis, Q fever, typhoid fever, and other occasional infections, as well as the implications on breastfeeding of the infants. Hepatitis during pregnancy with fever and systemic clinical presentations, which are not attributable to the common infectious agents, should raise the suspicion of infection with above-mentioned pathogens, and appropriate laboratory tests are required. Early recognition of severe hepatitis or acute liver failure is critical in initiating appropriate and specific therapy, together with systemic supportive care, to reduce maternal and fetal mortality and long-term sequelae.

Abstract
BACKGROUND Neonatal herpes simplex virus (HSV) infection and its implications have been well defined. Several methods are recommended to mitigate the risk of maternal transmission of HSV to the neonate, including CS, suppressive antiviral therapy for the mother, and prophylaxis for the infant. The utility of CS in women who present with a duration of rupture of membranes greater than 4 hours remains a question. CASE We present a case of a woman who presented following 10 hours of rupture of membranes with HSV genital lesions, suspected to be the result of untreated recurrent infection. A CS was done. CONCLUSION Extensive studies for the presence of HSV by PCR of the placenta and infant failed to detect the virus.

Abstract
Herpes simplex virus (HSV) infections in newborns are associated with severe disease and death. Trials conducted by the Collaborative Antiviral Study Group have established the standard of care for the treatment of neonatal HSV disease with marked improvements in morbidity and mortality. We review the studies that have contributed to our understanding of the epidemiology and clinical course of neonatal HSV disease and discuss the landmark trials that have resulted in safe and effective treatment together with improved diagnostics. Although significant advances have been made, neonatal HSV disease continues to have an unacceptably high mortality rate with significant sequelae in survivors. Further research is urgently needed for prevention.

Abstract
BACKGROUND Neonatal herpes infection is the most serious complication of Herpes Simplex Virus (HSV) infection during pregnancy and perinatal period. Few studies have reported neonatal HSV infection in developing countries. OBJECTIVES The aim of this study was to detect the HSV infection among neonates and infants with sepsis. MATERIALS AND METHODS In a cross sectional study all infants aged less than 3 months, admitted to neonatal intensive care unit and pediatric emergency ward of Ghaem Hospital (a university hospital with 900 beds) in Mashhad (Northeast of Iran) with clinical diagnosis of sepsis and at least one inclusion criteria during one year from November 2009 to October 2010, were enrolled in the study. Polymerase chain reaction (PCR) was done on clinical samples obtained from patients. RESULTS Among 150 neonates and infants younger than 3 months old with sepsis, the PCR results for detecting the HSV DNA, were positive in 6 samples of 5 patients (3.3 %). None of the mothers had symptomatic HSV infection during delivery. The mean age of the patients was 18 days. Two of them died due to shock and disseminated intravascular coagulation (DIC). CONCLUSIONS In neonates and infants with primary diagnosis of sepsis, HSV infection should be considered especially if the clinical condition does not improve after 48 hours of antibiotic therapy, and sepsis still exists with elevated liver enzymes.

Abstract
One of the most deleterious consequences of maternal infection with herpes simplex virus is neonatal herpes, which results in death or significant neurodevelopmental impairment in the majority of infected babies. Herpes simplex virus infection during pregnancy can also impact the psychologic health of the mother. The ability to minimize the risk of herpes simplex virus transmission has improved in tandem with advances in understanding of the mechanisms and epidemiology of acquisition of neonatal herpes simplex virus. In particular, antiviral pharmacotherapy is now recognized as an important option both for reducing the risk of transmission of herpes simplex virus from a seropositive to a seronegative partner and, potentially, for modifying several risk factors for transmission of the virus from a herpes simplex virus-infected mother to the neonate. This review discusses the consequences and management of herpes simplex virus infection during pregnancy, with a focus on the evolving role of antiviral therapy.

Abstract
BACKGROUND Neonatal herpes simplex virus (HSV) is a serious, life-threatening infection that is usually acquired during birth from contact with infected maternal genital secretions. Primary maternal HSV gingivostomatitis is a rare occurrence during pregnancy, and HSV type 1 (HSV-1) neonatal disease after primary maternal HSV gingivostomatitis during pregnancy has not been reported in detail. METHODS We reviewed the medical records of neonates (≤28 days of age) with a confirmed diagnosis of neonatal HSV-1 at a single pediatric center from January 1981 to January 2010 to identify cases in which the mother had primary gingivostomatitis during pregnancy or at term. RESULTS Seven neonates whose mothers had primary HSV-1 gingivostomatitis during pregnancy were identified from a review of 48 neonates with laboratory-proven HSV-1 neonatal disease. Of the 7 women, 2 presented with symptoms of primary HSV-1 gingivostomatitis during the first trimester and 5 in the third trimester. Three of the neonates developed skin, eye, and mucous membrane disease, 2 developed central nervous system disease, and 2 developed disseminated disease. One of the neonates with disseminated HSV-1 disease died. CONCLUSIONS Primary maternal HSV gingivostomatitis during pregnancy may lead to HSV-1 transmission to the neonate. Physicians caring for pregnant women should communicate the diagnosis of HSV gingivostomatitis to the neonate's primary provider to ensure proper surveillance, early evaluation, and prompt treatment.

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
BACKGROUND Neonatal herpes simplex virus (HSV) infection, while uncommon, is associated with substantial morbidity and mortality. However, there is little nationally representative data describing resource utilization. METHODS This retrospective cohort study was conducted using the Pediatric Health Information System, an administrative database that contains discharge diagnosis and resource utilization data from 35 free-standing children's hospitals. Patients <or=60 days of age with a primary discharge diagnosis of HSV were study eligible if they received intravenous acyclovir and were discharged between January 1, 2003 and December 31, 2005. RESULTS There were 406 patients with HSV. The median age was 16 days (interquartile range: 8-31 days); 52% of patients were female. Congenital heart disease, the most common congenital anomaly, occurred in 10% of patients. The median length of stay was 15 days; 21 (5%) patients died. HSV was associated with substantial resource utilization. The median hospital charge was $37,431 (interquartile range: $14,667-$74,559) per infant. The presence of congenital heart disease independently increased the hospital length of stay by 93% (adjusted LOS ratio: 1.93; 95% CI: 1.5-2.5). CONCLUSIONS HSV infection in neonates and young infants was associated with substantial resource utilization. The presence of an underlying congenital cardiac anomaly was associated with a significantly longer length of stay and higher hospital charges.

Abstract
Many women seek care for vulvar, vaginal, or pelvic complaints. Primary care providers should possess a solid understanding of the differential diagnosis and treatment of gynecologic infections. Many infections in the reproductive tract are sexually transmitted, whereas other common infections are attributable to an overgrowth of the normally present bacteria or yeast in the vagina. Presenting symptoms and signs are helpful in determining the source of infection, but often a battery of tests must be performed to make a definitive diagnosis.

Abstract
Herpes simplex virus (HSV) infection is one of the most common viral sexually transmitted diseases worldwide. The first time infection of the mother may lead to severe illness in pregnancy and may be associated with virus transmission from mother to foetus/newborn. Since the incidence of this sexually transmitted infection continues to rise and because the greatest incidence of herpes simplex virus infections occur in women of reproductive age, the risk of maternal transmission of the virus to the foetus or neonate has become a major health concern. On these purposes the Authors of this review looked for the medical literature and pertinent publications to define the status of art regarding the epidemiology, the diagnosis, the therapy and the prevention of HSV in pregnant women and neonate. Special emphasis is placed upon the importance of genital herpes simplex virus infection in pregnancy and on the its prevention to avoid neonatal HSV infections.

Abstract
The rate of cesarean deliveries has increased dramatically over the past decade. Studies to date have highlighted a number of factors on the part of the treating physician and the expectant mother contributing to this increase. Maternal infections are not a major cause of this increase. There are a limited number of infections in a pregnant woman that warrant cesarean delivery to prevent perinatal transmission. This article outlines those infections known to be transmitted perinatally through the infected birth canal and details the current recommendations for cesarean delivery. Pregnant women with active genital herpes lesions or with known herpes simplex virus infection and a prodromal illness consistent with recurrence at the time of presentation in labor should undergo cesarean delivery. Pregnant women who are HIV infected and have detectable viremia (>1000 copies/mL) should be counseled regarding the potential benefits of cesarean delivery as an adjunct to antiretroviral therapy. Hepatitis C virus (HCV) can be transmitted intrapartum, but prevention of HCV transmission by cesarean delivery has not been proved effective and is not generally indicated. A limited number of other infectious agents can be transmitted through the birth canal but do not constitute an indication for cesarean delivery.

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
OBJECTIVE To determine the incidence of possible neonatal herpes simplex virus (HSV) infections, HSV infection status of women with infected infants, and use of measures to reduce risk of HSV transmission to the neonate in a large US managed-care population. STUDY DESIGN Retrospective analysis of administrative claims from the Integrated Health Care Information Services National Managed Care Benchmark database. RESULTS Of 233,487 infants born to 252,474 mothers from January 1997 to June 2002, the numbers assigned an ICD-9 code reflecting possible neonatal HSV infection </=30 and </=90 days of birth were 178 (0.08%) and 338 (0.15%), respectively. Of the 338 mothers delivering infants with possible neonatal HSV </=90 days postnatally, 12% had a prior HSV diagnosis, 5% were prescribed an antiviral medication during the study period, and 3% used antiviral medication and had a cesarean delivery. CONCLUSION These results support national surveillance of neonatal HSV to better define its incidence, strengthen health policies, and improve prevention and treatment.

Abstract
Fetal growth restriction remains a major cause of perinatal morbidity and mortality in modern obstetric practice. Placental insufficiency is the most common association, but is often a diagnosis of exclusion. Currently, no treatment can ameliorate or reverse established growth restriction: maximising gestational age and judicious timing of steroid administration and delivery are the primary tasks for the obstetrician. Although comprehensive surveillance of the preterm fetus now includes ductus venosus Doppler studies, its effectiveness in timing delivery has yet to be confirmed in randomised controlled trials. More basic research on the regulation of fetal growth is needed before specific therapies for established growth restriction can be developed.

Abstract
Herpes simplex virus (HSV) infections are fortunately quite rare in the neonatal population. Nevertheless, due to their life-threatening nature and the tremendous damage that surviving infants can incur, neonatal HSV is actually considered in a differential diagnosis relatively commonly. The availability of safe and effective antiviral therapy for the management of neonatal HSV also can accelerate a clinician's decision to consider HSV as the cause of a neonate's disease presentation, and then to obtain appropriate diagnostic studies and empirically institute antiviral treatment. Decisions on whether to continue antiviral therapy for a full course are predicated on the appropriate interpretation of these diagnostic studies as they subsequently are reported to the treating physician. For HSV-infected neonates, the duration of parenteral acyclovir therapy ranges from 14 to 21 days, depending on the extent of disease. Use of subsequent oral suppressive antiviral therapy is under investigation in randomized controlled trials, and at this time cannot be routinely recommended. This article will summarize the current state of neonatal HSV disease presentation, diagnosis, and management.

Abstract
OBJECTIVE To determine whether herpes simplex virus type 2 (HSV-2) infection was associated with risk of intrapartum human immunodeficiency virus type 1 (HIV-1) transmission and to define correlates of HSV-2 infection among HIV-1-seropositive pregnant women. METHODS We performed a nested case control study within a perinatal cohort in Nairobi, Kenya. Herpes simplex virus type 2 serostatus and the presence of genital ulcers were ascertained at 32 weeks of gestation. Maternal cervical and plasma HIV-1 RNA and cervical HSV DNA were measured at delivery. RESULTS One hundred fifty-two (87%) of 175 HIV-1-infected mothers were HSV-2-seropositive. Among the 152 HSV-2-seropositive women, nine (6%) had genital ulcers at 32 weeks of gestation, and 13 (9%) were shedding HSV in cervical secretions. Genital ulcers were associated with increased plasma HIV-1 RNA levels (P=.02) and an increased risk of intrapartum HIV-1 transmission (16% of transmitters versus 3% of nontransmitters had ulcers; P = .003), an association which was maintained in multivariable analysis adjusting for plasma HIV-1 RNA levels (P=.04). We found a borderline association for higher plasma HIV-1 RNA among women shedding HSV (P=.07) and no association between cervical HSV shedding and either cervical HIV-1 RNA levels or intrapartum HIV-1 transmission (P=.4 and P=.5, [corrected] respectively). CONCLUSION Herpes simplex virus type 2 is the leading cause of genital ulcers among women in sub-Saharan Africa and was highly prevalent in this cohort of pregnant women receiving prophylactic zidovudine. After adjusting for plasma HIV-1 RNA levels, genital ulcers were associated with increased risk of intrapartum HIV-1 transmission. These data suggest that management of HSV-2 during pregnancy may enhance mother-to-child HIV-1 prevention efforts. LEVEL OF EVIDENCE II.

Abstract
Advances in the diagnosis of herpes simplex virus infections of the CNS have occurred rapidly over the past 10 years. The development and application of PCR technology to the detection of herpes simplex virus DNA from cerebrospinal fluid has resulted in tremendous improvements in the management of patients with suspected herpes simplex virus CNS infections, not the least of which is decreasing the necessity for invasive brain biopsy to establish the diagnosis. The pace of discovery has continued in recent years with the development of more rapid DNA amplification techniques that do not require postamplification analysis using amplified products (real-time PCR). However, despite the power of these new diagnostic modalities, test results must always be considered in the context of the patient, and physician judgment should never be usurped by technological advances. This article will summarize the advances in the diagnosis of herpes simplex virus CNS disease within the context of how these advances can enhance the care of individual patients.

Abstract
OBJECTIVE Calls for universal antenatal type-specific herpes simplex virus (HSV) screening to prevent neonatal herpes have recently increased and would affect the four million pregnant women and their partners annually in the United States. We undertook this review to assess the appropriateness of such screening, making relevant comparisons to established antenatal human immunodeficiency virus (HIV) and hepatitis B virus (HBV) screening programs. DATA SOURCES We conducted a full PubMed and bibliographic search for relevant literature in English available from 1966 through February 2006, using the terms "genital herpes," "neonatal herpes," "decision analysis" or "cost-effectiveness analysis," and "herpes and pregnancy" or "antenatal herpes screening." Comparison literature was obtained by replacing "herpes" with "HBV" or "HIV". METHODS OF STUDY SELECTION We appraised antenatal type-specific HSV screening using well-established criteria for a good screening program, which we articulated as questions. Of 455 articles we selected those that addressed at least one of the questions and were pertinent to the U.S. population. TABULATION, INTEGRATION, AND RESULTS We found that neonatal HSV is rare and its incidence is imprecisely defined. There is a lack of evidence supporting the effectiveness of interventions to prevent maternal acquisition of new infection in late pregnancy, which accounts for 60-80% of neonatal herpes. The consequences of universal screening are incompletely understood but include the potential for unnecessary cesarean deliveries and medical treatment, maternal psychosocial stress, and discord among partners. The available evidence indicates universal screening is not cost-effective. In contrast, antenatal HIV and HBV screening programs better satisfy accepted criteria for screening. CONCLUSION On the basis of this appraisal, universal antenatal type-specific HSV screening to prevent neonatal herpes does not adequately satisfy criteria of a good screening program, and we recommend against its adoption.

Abstract
OBJECTIVE To estimate the frequency of isolation of herpes simplex virus (HSV) from the genital tract when recurrent herpes lesions were present on the buttocks. METHODS Data were extracted from a prospectively observed cohort attending a research clinic for genital herpes infections between 1975 and 2001. All patients with a documented herpes lesion on the buttocks, upper thigh or gluteal cleft ("buttock recurrence") and concomitant viral cultures from genital sites including the perianal region were eligible. RESULTS We reviewed records of 237 subjects, 151 women and 86 men, with a total of 572 buttock recurrences. Of the 1,592 days with genital culture information during a buttock recurrence, participants had concurrent genital lesions on 311 (20%, 95% confidence interval [CI] 14-27%) of these days. Overall, HSV was isolated from the genital region on 12% (95% CI 8-17%) of days during a buttock recurrence. In the absence of genital lesions, HSV was isolated from the genital area on 7% (95% CI 4%-11%) of days during a buttock recurrence and, among women, from the vulvar or cervical sites on 1% of days. CONCLUSION Viral shedding of herpes simplex virus from the genital area is a relatively common occurrence during a buttock recurrence of genital herpes, even without concurrent genital lesions, reflecting perhaps reactivation from concomitant regions of the sacral neural ganglia. Patients with buttock herpes recurrences should be instructed about the risk of genital shedding during such recurrences. LEVEL OF EVIDENCE II-2.

Abstract
OBJECTIVE The goal was to determine incidence, determinants, and morbidity and mortality rates of neonatal herpes simplex virus infections in Canada. METHODS From October 1, 2000, to September 30, 2003, reports of neonatal herpes simplex virus infection were solicited actively from all Canadian pediatricians and pediatric subspecialists on a monthly basis. RESULTS Fifty-eight cases of neonatal herpes simplex virus were reported (5.9 cases per 100,000 live births). Cesarean section was performed in 24.6% of cases, 28.1% of patients were born prematurely, 28.6% had birth weights of < 2500 g, and 7.5% had Apgar scores of < 7 at 5 minutes of life. Mothers < 20 years of age and those reporting Aboriginal ethnicity were affected disproportionately; 40% of mothers had no history of genital herpes before delivery, and intrapartum genital lesions were present in only 1 of 58 cases. Of cases with known herpes simplex virus type, 62.5% were herpes simplex virus-1. Localized infections accounted for 59.6% of cases, whereas disseminated disease and central nervous system disease were reported for 17.5% and 22.8%, respectively. Localized infections were more likely to be herpes simplex virus-1 and disseminated and central nervous system infections herpes simplex virus-2. Nine of 58 cases were fatal. All cases with known treatment information (n = 55) were treated with intravenously administered acyclovir. CONCLUSIONS This is the first study to examine the national incidence of neonatal herpes simplex virus in Canada. Many women had no genital herpes simplex virus history before delivery, and the majority of cases were herpes simplex virus-1, which has implications for prenatal screening and vaccine/drug development. Follow-up monitoring of case subjects is being performed annually for 3 years, to be completed in October 2006.

Abstract
PURPOSE OF REVIEW To examine and evaluate ways of managing genital infections in pregnant women. RECENT FINDINGS The need to screen for sexually transmitted diseases during pregnancy depends on the prevalence of the condition, its pathogenesis and the cost-benefit analysis for a population or risk group. For a few genital infections with severe impact on the outcome of the pregnancy, such as syphilis and gonorrhoea, a 'screen and treat' policy is almost always cost-effective. SUMMARY Genital infections often remain unnoticed during pregnancy, as their signs and symptoms may be seen as part of the normal discomfort of pregnancy. Also it is sometimes not clear whether there are multiple partners or whether the partners have been treated, making re-infection after treatment highly likely. Partner tracing may be difficult, but the 'screen and treat' policy is usually the best solution.

Abstract
The endocrinologic, immunological, and vascular changes that occur during pregnancy are far-reaching. These systemic factors produce profound local impact on the physiology and pathology of the oral cavity, vagina, and vulva. Physiological changes can be expected and tolerable or of such severity that they are viewed as pathological. Existing disease can be exacerbated and dermatoses specific to pregnancy can erupt. Each of these conditions can pose potentially challenging treatment considerations.

Abstract
Primary infections with herpes simplex virus (HSV) and varicella-zoster virus (VZV) may lead to severe illness in pregnancy. Both diseases may be associated with transplacental virus transmission and fetal infection. Such infections can lead to intrauterine death, severe malformations and premature birth; the fetal/congenital varicella syndrome is well-defined. Herpes genitalis and varicella at the time of labor may lead to life threatening neonatal-herpes or varicella of the newborn. Currently neither active immunization nor neutralizing immunoglobulin is available for HSV infections. VZV-seronegative women in child-bearing age can be vaccinated and pregnant women exposed to VZV can be given specific immunoglobulins. While an infection is rarely blocked, the severity is generally reduced. For severe disease antiviral treatment is necessary, with valacyclovir and acyclovir represents the drugs of choice. Primary or recurrent overt disease of the genital tract at the time of delivery an indication for caesarean section. Suppression of recurrent genital herpes during the last weeks of pregnancy with valacyclovir and acyclovir reduces the need for surgical intervention. Neonates exposed to VZV should receive specific immunoglobulin. If neonates show signs of either infection, immediate treatment with acyclovir must be initiated.

Abstract
OBJECTIVE Potential strategies to prevent neonatal herpes include herpes simplex virus (HSV) serologic testing and counseling of pregnant women and rapid HSV polymerase chain reaction (PCR) testing of maternal genital secretions at delivery. The cost-effectiveness of these interventions would be improved if high-risk pregnancies could be easily identified for targeted testing. STUDY DESIGN Washington State birth certificate data for all singleton live births from 1987 through 2002 were linked with infant death and hospital discharge data for birth and subsequent hospitalizations in a population-based case-control study of risk factors for neonatal herpes. A case was defined as an infant with a discharge diagnosis of HSV infection (International Classification of Diseases 9th edition [ICD-9] code 054.X) from birth admission or readmission within 30 days of life. Five controls per case were frequency matched to cases by year of birth. RESULTS Ninety-one neonatal HSV cases were identified (8.4/100,000 live births). Risk factors for infection included maternal age younger than 25 years (adjusted odds ratio [aOR] = 1.9, 95% CI 1.1-3.3) and paternal age younger than 20 years or unknown (aOR = 1.7, 95% CI 0.7-3.7). Testing couples with either risk factor would require testing 36% of couples and could potentially prevent up to 60% of cases. Maternal history of genital herpes, fever during labor, and premature rupture of membranes were also associated with neonatal disease; using all risk factors identifiable at delivery would require screening 60% of pregnancies and identifying 84% of cases. CONCLUSION Targeted HSV testing would miss a substantial proportion of neonatal herpes.

Abstract
OBJECTIVE To assess ultrasound findings of a fetus with intrauterine growth retardation (IUGR) and skin damage, related to intrauterine herpes simplex virus (HSV) infection. METHODS A 23-year-old, G1, P0 woman was referred at 23.5 weeks' gestation (WG) for IUGR. The patient had a previous single episode of serotype 1 herpes progenitalis at 11 WG. Ultrasound examination revealed extensive skin changes with no cerebral involvement. The methods employed for evaluation of the disease included maternal serology, amniocentesis and repeated ultrasound examinations. RESULTS Maternal serology was positive for HSV1 and fetal infection was confirmed via polymerase chain reaction (PCR). At 27 WG, amniotic fluid index decreased and lower limb skin as well as abdominal skin was irregular. Oesophagus was thickened. In contrast, upper limb skin and cranial vault were thin and less visible. IUGR was predominant as regards bone parameters. After termination of pregnancy, the fetus showed macroscopic characteristics of HSV infection. Microscopic examination revealed only placental and skin lesions. CONCLUSIONS Our report illustrates a rare case of HSV1 intrauterine infection that occurred during the first trimester with bone and cephalic IUGR associated with extensive skin damage, and with no cerebral involvement.

Abstract
The majority of neonatal Herpes Simplex Virus (HSV) infections are acquired at birth as a consequence of direct fetal contact with the infected birth canal or through an ascending infection after premature rupture of the amniotic membranes. Intrauterine transmission of HSV infection from mother to the fetus is rare; in only 5% of the cases it occurs from haematogenous transplacental dissemination. We present a case of transplacental intrauterine HSV infection after a primary maternal HSV infection in the first trimester of pregnancy. The diagnosis was assessed by viral culture and serologic tests. Ultrasound imaging revealed fetal brain damage in the third trimester. Finally, the MRI showed the devastating extensiveness of the HSV infection, which was beyond the expectation based on the ultrasound images.

Abstract
Growing understanding of the mechanisms and epidemiology of neonatal herpes simplex virus acquisition allows for the development of a new management of the pregnant patient, one that will reduce the risk of transmitting herpes to the newborn. Maternal herpes simplex virus infection, especially acquired during pregnancy, can result in transmission to the newborn. Infection of the CNS of the newborn results in death or significant neurodevelopmental impairment in most of these infected babies. Herpes simplex virus infection acquired prior to or during pregnancy has a physical and psychologic impact on the health of the mother. Newer, more sensitive and specific serology testing for herpes simplex virus in combination with antiviral pharmacotherapy is now recognized as an important option for reducing the risk of herpes simplex virus transmission from mother to newborn. This review discusses new information concerning the prevention, diagnosis and treatment options for the management of herpes simplex virus infection during pregnancy with a focus on the evolving role of prevention.

Abstract
Of the commonly considered congenital infections, those caused by cytomegalovirus (CMV), syphilis, and herpes simplex virus (HSV) are frequently (CMV, HSV) or exclusively (syphilis) acquired sexually by the mother, with subsequent transmission to the developing fetus. Of the other commonly considered congenital infections, including rubella and toxoplasma infections, the mother is exposed to the infectious agent via interpersonal or environmental contacts. Unlike each of these other pathogens, which are transmitted transplacentally to the developing fetus following maternal infection though, HSV usually is transmitted perinatally as the neonate is exposed to the virus during passage through an infected birth canal. This difference in timing of acquisition of infection has had important consequence in the therapeutic advances achieved during the last 30 years in the management of neonatal HSV infections. Because the time period between the acquisition of infection and initiation of effective antiviral therapy is shorter in neonatal herpes than in congenital toxoplasmosis or CMV infections, the outcomes of therapy have the potential to be markedly different. This article will summarize the current state of neonatal HSV disease presentation, diagnosis, and management.

Abstract
Neonatal herpes simplex virus (HSV) infection usually is acquired during the birth process, as the neonate comes in contact with the virus during passage through an infected birth canal. After an incubation period which can last as long as 2 to 4 weeks, neonatal HSV disease then manifests in 1 of 3 ways: (1) disseminated disease, with visceral organ involvement (including infection of the brain in two-thirds to three-quarters of patients); (2) central nervous system disease (with no other visceral organ involvement, but with skin lesions in two-thirds of patients); or (3) disease limited to the skin, eyes, and/or mouth (ie, SEM disease). Diagnostic advances in recent years have focused primarily on applying polymerase chain reaction technology to babies suspected of having neonatal HSV disease. Treatment of neonatal HSV disease with intravenous acyclovir has improved the likelihood of survival substantially, although neurologic morbidity remains a common sequelae, especially among survivors of central nervous system disease. Despite these advances, the duration of time from onset of symptoms and initiation of antiviral therapy has remained unchanged for the past 20 years. The surest way to improve outcomes rapidly at this point is to raise awareness of neonatal HSV disease, resulting in the establishment of earlier diagnoses and more rapid institution of antiviral therapy. In the longer term, development of a bedside nucleic acid detection kit for real-time detection of HSV DNA in the maternal genital tract at the time of delivery could identify which babies are at risk of developing neonatal HSV disease.

Abstract
BACKGROUND Oral acyclovir is commonly used for genital herpes and other herpesvirus infections. Data on potential fetal risk are extremely limited. From 1984 to 1998, the Acyclovir in Pregnancy Registry monitored birth outcomes of women exposed to oral or intravenous acyclovir during pregnancy. This report describes the final results. METHODS The registry was publicized to health care providers most likely to diagnose pregnancy; providers called the registry telephone number, then mailed in a brief questionnaire. Pregnancy outcomes were categorized either as outcomes with birth defects or outcomes without birth defects, subcategorized as live births, spontaneous pregnancy losses (including stillbirths), and induced abortions. Birth defects were defined using a modification of the CDC definition for birth defects surveillance systems. Observed rates were compared to the rate (3.2%) of birth defects expected in the general population. RESULTS Between June 1, 1984 and June 30, 1998, 1695 pregnancies exposed to oral or IV acyclovir were registered; 461 (27%) were lost to follow-up. A total of 1234 pregnancies in 24 countries were followed, with a total of 1246 outcomes. Among 1246 pregnancy outcomes, 756 involved acyclovir exposure in the first trimester, 197 in the second trimester, and 291 in the third trimester. Among live births with first trimester acyclovir exposure, risk of birth defects was 19 of 596 (3.2%; 95% CI, 2.0-5.0%). No unusual defects or pattern of defects were apparent. CONCLUSIONS The observed rates and types of birth defects for pregnancies exposed to acyclovir did not differ significantly from those in the general population.

Abstract
BACKGROUND Herpes simplex virus (HSV) type-specific serological tests are now widely available, but indications for their use have not been well defined. The California Sexually Transmitted Diseases (STD) Controllers Association convened a committee of clinicians and researchers to make recommendations for the use of type-specific HSV type 2 (HSV-2) serological tests. METHODS By means of a systematic review of the literature, evidence to support screening in selected high-risk groups was compiled. Screening recommendations were developed by applying standard screening criteria to each specific population. RESULTS The committee concluded that, in addition to serological testing for the diagnostic evaluation of patients with symptoms, screening of asymptomatic patients is likely to be beneficial among the following groups: those at high risk for STDs and human immunodeficiency virus (HIV) infection who are motivated to reduce their sexual risk behavior, HIV-infected patients, and patients with sex partners with genital herpes. In contrast, universal screening for HSV-2 infection in pregnant women is unlikely to be beneficial. CONCLUSIONS The targeted use of HSV-2 serological tests for specific diagnostic situations and selected populations should benefit patients, providers, and the community. Until more data become available, these recommendations provide justification for selective diagnostic and screening uses of HSV-2 serological tests.

Abstract
As many as 2,500 infants develop neonatal herpes each year, most of whom are born to women with no history or physical findings suggestive of genital herpes. Infection usually takes one of three forms: 1) disease localized to skin, eyes, and mucous membranes, 2) localized central nervous system infection, or 3) disseminated infection. Exposure to the virus occurs during passage through an infected birth canal, but 5% of infants acquire the infection in utero. The mortality rate is 31% for disseminated infection and 6% for localized central nervous system disease; long-term neurologic sequelae are seen in 17% and 70% of survivors, respectively. Diagnosis is made by isolating of the virus from skin lesions or other involved sites. The polymerase chain reaction for the detection of viral DNA in cerebrospinal fluid or serum is now the diagnostic test of choice for central nervous system or disseminated neonatal herpes because it has higher sensitivity than traditional culture methods. Treatment is with high-dose intravenous acyclovir (60 mg/kg per day in three divided doses), with adjustments made for infants with renal or hepatic insufficiency. Supportive measures and neuroimaging studies are often required. Acyclovir is administered for three weeks, but infants with disease localized to the skin, eyes, and mucous membranes can be treated for two weeks if the cerebrospinal fluid polymerase chain reaction assay is negative for herpes simplex virus DNA. Prevention of infection in infants can be accomplished by cesarean delivery when women have active lesions at the onset of labor. Neonates delivered through an infected birth canal should be screened between 24 and 48 hours of age with viral cultures of eyes, nasopharynx, mouth, and rectum. If positive, they should be treated with acyclovir even if asymptomatic. Suppressive acyclovir therapy beginning at 36 weeks gestation is often prescribed for women with frequent recurrences of genital herpes.

Varicella zoster virus (VZV), herpes simplex virus (HSV) and cytomegalovirus (CMV) are all members of the Herpesviridae family.Humans are the only source of infection for these double stranded DNA viruses. Infants may acquire these infections in utero, peripartum, or postnatally, resulting in a variety of clinical syndromes, ranging from asymptomatic infection to severe infection,with high mortality rates and significant long-term morbidity. This article presents the epidemiology, clinical characteristics, treatment,and prevention strategies for VZV, HSV, and CMV infections in infants.

Abstract
Tremendous advances have occurred over the past 30 years in the diagnosis and management of neonatal herpes simplex virus (HSV) disease. Mortality in patients with disseminated disease has decreased from 85 to 29%, and that in patients with central nervous system (CNS) disease has decreased from 50 to 4%. Morbidity has been improved more modestly: the proportion of patients with disseminated disease who are developing normally at 1 year has increased from 50 to 83%. While the proportion of patients with neurologic morbidity following CNS disease has remained essentially unchanged over the past three decades, the total number of patients who are developing normally following HSV CNS disease has increased due to the improved survival. Although additional therapeutic advances in the future are possible, more immediate methods for further improvements in outcome for patients with this potentially devastating disease lie in an enhanced awareness of neonatal HSV infection and disease. A thorough understanding of the biology and natural history of HSV in the gravid woman and the neonate provides the basis for such an index of suspicion and is provided in this article.
