Toxoplasma gondii is a widespread parasitic pathogen that infects over one third of the global human population. The parasite invades and chronically persists in the central nervous system (CNS) of the infected host. Parasite spread and persistence is intimately linked to an ensuing immune response, which does not only limit parasite-induced damage but also may facilitate dissemination and induce parasite-associated immunopathology. Here, we discuss various aspects of toxoplasmosis where knowledge is scarce or controversial and, the recent advances in the understanding of the delicate interplay of T...

Zika virus (ZIKV) infection during pregnancy is associated with microcephaly and other birth defects, collectively termed Congenital Zika Syndrome (CZS). During the epidemic in 2015-16, ZIKV spread through the Americas and quickly joined the list of other known teratogenic pathogens, TORCH. Multiple ZIKV vaccines have been developed for protection of pregnant women and women of childbearing age. However, ZIKV infection incidence has since waned substantially, and adverse birth outcomes are rare outcomes of infection...

Mother-to-child transmission of syphilis remains a major global public health issue, and elimination of congenital syphilis is one of the millennium development goals of the World Health Organization (1). In 2012, an estimated 930,000 maternal syphilis infections caused 350,000 adverse pregnancy outcomes, including 143,000 early fetal deaths and stillbirths, 62,000 neonatal deaths, 44,000 preterm or low-weight births, and 102,000 infected infants worldwide (2). In China, the number of congenital syphilis cases reported annually increased from 468 in 2000 to 10,032 in 2013; the corresponding national congenital syphilis incidence rate increased nearly 26-fold, from 2...

A foetus affected by a congenital rubella infection can develop congenital rubella syndrome (CRS). Aniridia is the absence of iris, rarely been described in literature in association with CRS, can easily be overlooked, leading to complications e.g. glaucoma and blindness later in life. We report a case of a neonate with CRS and aniridia presenting at a tertiary care hospital.

The risk of Zika virus (ZIKV) infection during pregnancy depends on the incidence of the disease, which is highly variable in different affected geographic areas (<1% to 75%). Among infected pregnant women, the risk of any adverse fetal/neonatal outcome was estimated at 5-42%, with 1-4% of fetal loss and 4-9% of suspected CZS. The estimated rate of maternal-fetal transmission ranges between 7% and 26%, depending on the methodology of the study. Findings associated with CZS are microcephaly (33-64%), ventriculomegaly (63-92%), calcifications (71-92%), malformations of cortical development (79-82%), anomalies of the corpus callosum (71-100%) and of the posterior fossa (21-82%), arthrogryposis (10-25%), eye abnormalities (25%), and extra-neurologic signs such as intra uterine growth restriction (14%), placentomegaly, transient hepatitis, mild anemia...

OBJECTIVES/HYPOTHESIS: Thyroglossal duct cysts (TGDCs) are the most common congenital neck cyst and typically present in childhood or adolescence, although a subset remains asymptomatic until adulthood. Although treatment involves surgical excision, few large-scale studies exist regarding the risks of surgical treatment of TGDCs in adults. This study aims to describe the characteristics of adult patients undergoing TGDC excision and to analyze risk factors associated with reoperation or other postoperative complications...

INTRODUCTION: Experts of pediatric endosurgery recommend early thoracoscopic resection of congenital pulmonary airway malformations (CPAM) even in asymptomatic infants due to the risk of later infections. However, neither the rate of lower airway inflammation nor the underlying microbes and their pathogenic potential have been revealed in CPAMs yet. Using latest gene-sequencing techniques, we present the first study analyzing the pulmonary microbiome in young asymptomatic infants with CPAM...

Toxoplasmosis is caused by the globally distributed protozoan parasite Toxoplasma gondii (phylum Apicomplexa); the disease can be clinically important for almost all homeothermic animals, including birds and humans. Toxoplasmosis course involves general clinical signs, such as fever, anorexia, or dyspnea, and more specific signs with neural, respiratory, cutaneous, or ocular involvement. Because of the wide range of clinical signs, the diagnosis in domestic and pet animals can be complicated. Hence, this review aims to provide a comprehensive analysis of some scarcely discussed aspects of toxoplasmosis, such as ocular and cutaneous manifestations, congenital infections, influence of T...

Sufficient internal fixation for occipitocervical (OC) or C1-C2 instability in pediatric patients with Down syndrome is difficult owing to small osseous structures, congenital deformities, and immature ossification. The purpose of this study was to evaluate the clinical outcomes of patients aged 8 years or younger with Down syndrome who underwent OC or C1-C2 fusion using freeze-dried allograft as bone graft substitute. The participants included seven consecutive patients aged 8 years or younger with Down syndrome who were treated for upper cervical disorders with posterior OC or C1-C2 fusion using freeze-dried allografts at our hospital between 2007 and 2016 and had a minimum follow-up of 1 year...

To achieve a contemporary understanding of the common and rare lesions that affect wild, urban Norway rats ( Rattus norvegicus), we conducted a detailed pathology analysis of 672 rats from Vancouver, British Columbia, Canada. Grossly evident lesions, such as wounds, abscesses, and neoplasms, were present in 71 of 672 rats (11%) and tended to be severe. The most common and significant lesions were infectious and inflammatory, most often affecting the respiratory tract and associated with bite wounds. We assessed a subset of rats (up to n = 406 per tissue) for the presence of microscopic lesions in a variety of organ systems...

Fibropolycystic liver diseases, also known as ductal plate malformations, are a group of associated congenital disorders resulting from abnormal development of the biliary ductal system. These disorders include congenital hepatic fibrosis, biliary hamartomas, polycystic liver disease, choledochal cysts and Caroli disease. Recently, it has been thought to include biliary atresia in this group of diseases, because ductal plate malformations could be implicated in the pathogenesis of this disease. Concomitant associated renal anomalies can also be present, such as autosomal recessive polycystic kidney disease (ARPKD), medullary sponge kidney and nephronophthisis...

Zika virus (ZIKV) can cause devastating congenital syndrome in fetuses from pregnant women and autoimmune disorder Guillain-Barré syndrome in adults. No clinically approved vaccine or drug is currently available for ZIKV. This unmet medical need has motivated a global effort to develop countermeasures. Several promising ZIKV vaccine candidates have already entered clinical trials. In contrast, antiviral development of ZIKV is lagging behind. Here, we review the overall strategies for ZIKV drug discovery, including (i) repurposing of clinically approved drugs, (ii) viral replication-based phenotypic screening for inhibitors, and (iii) targeted drug discovery of viral proteins...
