Abstract
OBJECTIVE The recent recrudescence of syphilis among women of childbearing age is associated with an increasing number of cases of congenital syphilis. We aimed to summarize the fetal and neonatal abnormalities due to congenital syphilis infection, particularly signs amenable to prenatal diagnosis. METHODS Eligible studies were retrieved from the PubMed collection database. Articles focusing on postnatal and antenatal abnormalities covered the periods from 1969 to 2019 and 1975 to 2019, respectively. This review included cohort studies, case series and case reports reporting findings regarding congenital syphilis infections described before and/or after birth. Articles were reviewed by three experts in prenatal diagnosis, and all findings were classified as amenable or not amenable to prenatal diagnosis. RESULTS A total of 432 cases of congenital syphilis infection were reported. Abnormalities were described antenatally in 161 cases, postnatally in 319 cases, and in both the antenatal and postnatal periods in 57 cases. The most frequently reported signs amenable to prenatal diagnosis were abdominal abnormalities (hepatomegaly, splenomegaly, and bowel abnormalities), fetal growth restriction, and elevated middle cerebral artery peak systolic velocity in the context of ascites or atypical hydrops. Brain abnormalities were rare and never isolated. In the neonatal period, the most common abnormalities were hepatosplenomegaly, bone damage and skin lesions. CONCLUSION We found that no individual sonographic sign or pattern of signs is pathognomonic for fetal syphilis. In fetuses with ultrasound abnormalities suggestive of congenital infection, syphilis must be considered as part of the work-up. This article is protected by copyright. All rights reserved.

Abstract
Background Neonatal jaundice is common, and despite the considerable medical costs associated with it, there are still few studies on the maternal factors associated with it. Identification of maternal factors associated with neonatal jaundice is very important in terms of prevention, screening and management of neonatal jaundice. The current study aimed to identify maternal disease factors associated with neonatal jaundice. Methods We compared the maternal disease diagnostic codes during pregnancy (study A) and 1 year before conception (study B) in mothers whose insurance claims data included newborns treated for neonatal jaundice before birth registration via the National Health Insurance Service–National Sample Cohort (control group). To decrease the effect of confounding variables, the neonatal jaundice and control groups were matched at a ratio of 1:10 via propensity score matching using covariates including age and income. Results The matched samples for studies A and B included 4,026 and 3,278 (jaundice group: 366 and 298) delivery cases, respectively. In both studies, the jaundice group had a higher proportion of patients who underwent cesarean section than the control group. In study A, other diseases of the digestive system had the highest odds ratio (OR) (K92; adjusted OR: 14.12, 95% confidence interval [CI]: 2.70–82.26). Meanwhile, gastritis and duodenitis had the lowest OR (K29; adjusted OR: 0.39, 95% CI: 0.22–0.69). In study B, salpingitis and oophoritis had the highest OR (N70; adjusted OR: 3.33, 95% CI: 1.59–6.94). Heartburn had the lowest OR (R12; adjusted OR: 0.29, 95% CI:0.12–0.71). Conclusions This study identified maternal disease factors correlated with neonatal jaundice during pregnancy and 1 year before conception. Maternal risk factors for neonatal jaundice included syphilis and leiomyoma during pregnancy, and salpingo-oophoritis before pregnancy. The protective factors included infection, inflammatory diseases, and dyspepsia.

Abstract
OBJECTIVES to identify the scientific evidence about the clinical complications and manifestations of congenital syphilis and aspects related to its prevention. METHODS integrative review after a search in the databases LILACS and MEDLINE, carried out in March 2018, using the descriptors "syphilis, congenital", "complications", and "signs and symptoms", leading to the selection of 27 researches. RESULTS the publications found were published from 1966 to 2017, and most of them were from Latin America and Africa. Negative outcomes, laboratory changes, and the clinical manifestations in congenital syphilis, whether early or delayed, were, respectively: low weight at birth, anemia, hepatosplenomegaly, and dental alterations. The lack of treatment of the pregnant women in the prenatal was the most common occasion in which the opportunity to prevent the complications of congenital syphilis was lost. CONCLUSIONS the scientific evidences analyzed showed serious complications of congenital syphilis that could be avoided if early opportunities of diagnosing and treating the pregnant women are not lost during the prenatal.

Abstract
We report a case of a preterm infant with congenital syphilis who presented with non-immune hydrops fetalis. Hepatic dysfunction was present at birth and acutely worsened following antibiotic administration. Placental pathology demonstrated infiltration with numerous spirochetes. Although critically ill, the infant recovered with intravenous penicillin G and supportive care. This case demonstrates that congenital syphilis remains a contemporary disease demanding enhanced awareness from clinicians. Manifestations evident in utero or in the newborn can be severe and may result in fetal demise or neonatal death. Moreover, we hypothesize that the treatment resulted in a Jarisch-Herxheimer reaction as manifested by the hepatic deterioration. The incidence of congenital syphilis and its associated complications can be greatly reduced with strict adherence to universal prenatal testing and comprehensive follow-up.

Abstract
Congenital syphilis (CS) is a disease that continues to persist in the United States despite its preventable nature. Mother-to-child transmission of CS can be avoided with appropriate maternal diagnosis and treatment during the pregnancy. Diagnosing CS and determining the therapeutic course can be challenging. This review covers the recent guidelines for the diagnosis and treatment of CS and the various factors that affect management decisions. These factors include the mother's antenatal management, the infant's clinical presentation and results, laboratory and serologic testing, and more.

Abstract
PURPOSE OF REVIEW Untreated syphilis may have profound adverse effects on pregnancy outcome, resulting in spontaneous abortion, stillbirth, premature delivery or perinatal death, or can result in significant morbidity during infancy, childhood or adolescence. In this article, we review current strategies for the management of maternal and congenital syphilis nationally and in resource-poor settings. RECENT FINDINGS Since 1998, a dramatic increase in syphilis diagnoses has been documented among women of child-bearing age in the UK and elsewhere. The low prevalence of congenital syphilis in many developed countries may have led to complacency, hindering modern-day management of this historically important condition. Follow-up studies indicate that present antenotal and postnatal interventions could be improved. This conclusion extends to resource-poor settings endemic for syphilis in which rapid diagnostic techniques are currently being validated. SUMMARY A stringent follow-up of pregnant women with syphilis before delivery and a proactive approach to identifying and treating exposed neonates born to such patients are needed.

Abstract
Neonatal alopecia has been described in many circumstances but never as a part of the constellation of signs in congenital syphilis. Common clinical features of early congenital syphilis include hepatosplenomegaly, skeletal deformities, hematologic disturbances, and mucocutaneous features such as rhinitis and maculopapular rash. Syphilitic alopecia has previously been described only in conjunction with secondary syphilis. In this article, we describe the first occurrence of alopecia in a neonate with congenital syphilis.

Abstract
Syphilis rates in women and congenital syphilis rates have declined steadily in the United States in recent years. However, syphilis remains a worldwide public health problem, with more than 12 million cases in adults and more than half a million pregnancies affected yearly. Prenatal screening and treatment programs are limited or nonexistent in many developing countries. The genome of Treponema pallidum, one of the smallest among prokaryotes, has been sequenced, but methods for continuous in vitro cultivation of the microbe remain elusive. There are no promising candidates for future vaccines at this time. Serologic testing, for both specific treponemal and nontreponemal antibodies, continues to be a primary means of diagnosis. Penicillin remains the drug of choice for congenital and acquired syphilis in childhood. The diagnosis of syphilis beyond early infancy raises concerns for possible child sexual abuse, although progression of congenital syphilis may account for some cases. Syphilis is a potentially eradicable disease, but this can be achieved only with sustained international will and cooperation to fund the necessary screening and treatment programs.

Abstract
One of the major medical concerns in neonates is their vulnerability to life-threatening complications. Early diagnosis of potentially serious medical conditions is essential in prevention of such complication by prompt administration of appropriate treatments. Recognition of cutaneous manifestations of potentially fatal diseases may assist a clinician in management of newborns. To overview the full spectrum of this category of conditions, Medline search was performed for cases of cutaneous manifestations associated with mortality during the first month of live that were published in the English language literature since 1977. This is a concise review of the clinical aspects of most of the potentially life-threatening disorders in neonates divided by basic morphology of their cutaneous manifestations.

Abstract
Syphilis is a chronic disease with a waxing and waning course, the manifestations of which have been described for centuries. It occurs worldwide, and the incidence varies significantly with geographic location. Transmission is mainly by sexual contact. The causative organism, Treponema pallidum, was first described in 1905, but because of the inability to culture the organism and the limitations of direct microscopy, serologic testing is the mainstay of laboratory diagnosis. The disease has been arbitrarily divided into several stages. The primary stage is defined by a chancre at the site of inoculation. The secondary stage is characterized by a polymorphic rash, lymphadenopathy, and other systemic manifestations. A variable asymptomatic latent period follows, which for epidemiologic purposes is divided into early (<1 year) and late (>1 year) stages. The early stages (primary, secondary, and early latent) are potentially infectious. The tertiary stage is the most destructive and is marked by cardiovascular and neurologic sequelae and gummatous involvement of any organ system. Congenital infection may result in protean early or late manifestations. Unlike many other bacteria causing infectious diseases, the organism remains sensitive to penicillin, and this remains the mainstay of therapy.

Abstract
The aim of this work was to disclose risk factors associated with birth defects which were heterogeneously distributed in the different geographic regions sampled by the Latin American Collaborative Study of Congenital Malformations (ECLAMC). The material included 2,159,065 hospital births, delivered in the 1967-1989 period in 24 geographic regions of Latin America. Birth defect types with 50 case-control pairs or more were analyzed. A risk factor was defined as that available variable with differential geographic rates, correlated with those of a given birth defect type. Identified factors were tested by case-control multivariate logistic regression to confirm their role in the occurrence of the defect. Altitude and maternal acute illness during first trimester of pregnancy, named influenza, were risk factors for microtia. Prenatal drug exposure, mainly sex hormones, were connected with the occurrence of hypospadias in low frequency areas, while Native ancestry was a "protective" factor in the same regions. Acute (influenza), and chronic (epilepsy and syphilis) maternal illness during first trimester of pregnancy and gravidity higher than four were risk factors for cleft lip. The independence of these variables from maternal age suggested that low maternal socioeconomic level could explain the high birth defect order and, perhaps, syphilis in mothers. Postaxial polydactyly was associated with parental consanguinity, as well as Afro-American ancestry, suggesting genetic heterogeneity.

Abstract
A variety of infectious agents have been associated with nonimmune hydrops fetalis, most notably parvovirus B19, cytomegalovirus, herpes simplex virus, Toxoplasma gondii, and Treponema pallidum. These agents produce hydrops through effects on fetal bone marrow, myocardium, or vascular endothelium. Knowledge of the epidemiology and clinical characteristics of maternal and fetal infection can be used to select a diagnostic approach. Etiologic diagnosis will guide prognosis and the selection of specific chemotherapy.

Abstract
During the 4-year period February 1989 to January 1993, 13 premature babies aged 1-21 days and with congenital syphilis were admitted to the National Cheng Kung University Hospital. Of the 13 premature infants, 8 (62%) had unusual desquamation over palms and soles. Bone changes with periosteal reaction and/or metaphyseal dystrophy were observed in 11 cases (85%). Three mothers were diagnosed as being infected during pregnancy; 2 were treated with penicillin. The clinical features of congenital syphilis in premature neonates are somewhat different from those previously reported. Bone changes, hepatosplenomegaly, respiratory distress, skin lesions, especially over the soles and palms, cerebrospinal fluid abnormalities, and jaundice were the major manifestations in our series. In premature infants with these symptoms and signs, congenital syphilis should be considered as one of the differential diagnoses. Once the diagnosis of congenital syphilis is made, adequate penicillin therapy should be given.

Abstract
OBJECTIVE To determine the performance of the FTA-ABS (IgM) test in congenital syphilis after eliminating interference by IgM rheumatoid factor (RF) and preventing competitive inhibition by IgG. DESIGN The FTA-ABS (IgM) test was carried out before and after RF removal (achieved by immunoprecipitation of the IgG) in infants with congenital syphilis and controls. SETTING Newborns delivered in the Peninsula Maternal and Neonatal Services in Cape Town and infants presenting at Red Cross War Memorial Children's Hospital. SUBJECTS Infants with congenital syphilis aged 0-4 months were divided into those with clinical signs at presentation and those who were asymptomatic at delivery. In addition, patients without congenital syphilis but with similar clinical signs at presentation were investigated as were control infants. OUTCOME MEASURE The diagnosis of congenital syphilis was based on the criteria suggested by Kaufman et al (1977). RESULTS Amongst symptomatic infants with congenital syphilis the FTA-ABS (IgM) test was positive in 34 (92%) of 37 cases prior to abolishing the RF effect and in 29 (78.4%) of 37 cases afterwards (p = 0.19). In 12 cases of congenital syphilis who were asymptomatic at birth, 10 had positive FTA-ABS (IgM) tests before RF removal and only three had positive tests afterwards (p = 0.006). False positive tests were not found amongst 15 symptomatic infants whose clinical features mimicked those of the infants with congenital syphilis. Among 51 healthy infants the test had a false-positive rate of 2% in newborns and 13% in older infants. The false positive reactions were eradicated by IgG precipitation. CONCLUSIONS Following IgG and RF removal there was an improvement in the specificity of the FTA-ABS (IgM) test but this was at the expense of a loss of sensitivity, particularly in asymptomatic newborns. For newborns, if the FTA-ABS (IgM) test was positive, the patient was likely to require treatment for congenital syphilis, regardless of whether the result was due to the presence of RF or specific IgM.

Abstract
Intrauterine infection with syphilis was diagnosed by reactive maternal serologic studies, ultrasonographic findings, and exclusion of other causes in three hydropic fetuses at 31, 34, and 35 weeks' gestation. With penicillin therapy and preterm delivery all infants survived through the perinatal period. Intrauterine infection that follows syphilis is a potentially treatable cause of nonimmune hydrops.

Abstract
As autopsy rates in general hospitals decline, interest in the perinatal autopsy continues to rise, reflecting the emergence of a vigorous specialty growing in parallel with fetal medicine, prenatal diagnosis and clinical genetics. Perinatal autopsies are best carried out in tertiary centres which provide these services. Meticulous documentation, flexibility of technique, intelligent use of laboratory tests and wide systematic histopathologic sampling are emphasized. Microbiologic examination is of particular value when carried out by a laboratory having a special interest in genital tract and perinatal pathogens. Karyotyping must be selective if resources are to be conserved and is most productive when there are multiple malformations. Perinatal autopsy is not complete without examination of the placenta and significant lesions should be clearly distinguished from curiosities and from changes secondary to fetal death. The pathologist's wider contribution to perinatal medicine includes providing high quality data to epidemiology units and auditing committees, contributing to the multidisciplinary management of prenatally diagnosed fetal abnormalities, monitoring iatrogenic disease patterns and supporting the process of perinatal grief management. Special problems and diagnostic challenges are to be found when investigating sudden, unexplained intrauterine fetal death, hydrops, bone dysplasias and complicated multiple pregnancies.

Abstract
Congenital syphilis (CS) has been and continues to be a principal public health problem in developing countries. Despite the wide experience acquired, physicians still have problems in diagnostic evaluation. We report 145 cases of CS at the Central Hospital, Maputo, emphasizing the differences in clinical features and in the results of serological and X-ray examinations between the neonatal and post-neonatal age groups. In the post-neonatal age group, the clinical expression of CS is mostly overt. It is commonly recognized that manifestations of CS in the neonatal age group are often poor or negative, yet a relevant percentage of CS that we report were fully symptomatic. In the neonatal age, the Venereal Disease Research Laboratory (VDRL) test in the mother and characteristic osteochondritic lesions on X-ray examination of the long bones help to make the diagnosis; in the post-neonatal age group, the VDRL test in the child is more often positive than in the mother and X-ray examination shows most periostitic lesions.

Abstract
A prospective study of newborns whose mothers had untreated or inadequately treated syphilis was undertaken. The infants were followed up for 3-4 months to ascertain whether they had congenital syphilis. A number of variables were analysed as possible predictive factors for the development of congenital syphilis. A maternal Venereal Disease Research Laboratory (VDRL) titre of 1:32 or above indicated which infants would develop congenital syphilis with a sensitivity of 93% and a specificity of 78%. The risk of a congenitally infected infant was significantly higher amongst the group of untreated mothers (p = 0.036). Low birthweight per se did not appear to be a predictor of the subsequent diagnosis of congenital syphilis. Using these simple predictive factors it may be possible to determine which at-risk infants would most benefit from careful supervision or a full 10-day course of therapy.
