Perineal tears are common during vaginal delivery and are associated with significant maternal morbidity. While chorioamnionitis and intrapartum fever are known to affect labor dynamics and perineal tissue integrity, their relationship with perineal trauma in spontaneous vaginal deliveries has not been established. This study aimed to evaluate the prevalence of perineal tears among women with intrapartum fever who delivered spontaneously. This retrospective cohort study included women who underwent spontaneous vaginal delivery during 2013–2021 in Israel. The study group comprised women diagnosed with intrapartum fever (≥38 °C), while afebrile women served as controls in a 1:2 ratio matched by age (<35 or ≥35 years) and gestational age (preterm/term). Perineal tears were classified according to the Royal College of Obstetricians and Gynaecologists (RCOG) criteria. Multivariable logistic regression was performed to adjust for statistically significant variables including obesity, induction of labor, epidural analgesia, amniotomy, delivery week, gestational diabetes, birth number, duration of the second stage of labor, and episiotomy. The cohort included 373 women with intrapartum fever and 746 controls. The overall rate of perineal tears was similar between febrile and afebrile women (42% vs. 40%; adjusted odds ratio [aOR] 0.99, 95% confidence interval [CI] 0.72–1.36). However, the rate of obstetric anal sphincter injury (OASIS) was lower among women with intrapartum fever (0.5% vs. 2.0%; aOR 0.10, 95% CI 0.02–0.52). Intrapartum fever was associated with higher rates of postpartum hemorrhage, manual exploration of the uterus, endometritis, anemia, and blood transfusion. Bacterial cultures were positive in 31% of febrile women, predominantly Escherichia coli and Group B Streptococcus, without association with perineal trauma. Alltogether, Intrapartum fever did not increase the risk of perineal tears in spontaneous vaginal deliveries and was paradoxically associated with a lower rate of OASIS. Further studies are warranted to explore the underlying physiological mechanisms linking temperature and perineal tissue resilience. Full article

Nontuberculous Mycobacteria (NTM), often referred to as environmental or atypical mycobacteria, are opportunistic pathogens phylogenetically as well as clinically distinct from both the Mycobacterium tuberculosis complex and Mycobacterium leprae. In the pediatric age group, NTM disease manifests with a diverse range of clinical phenotypes. Cervicofacial lymphadenitis stands out as the most common presentation among children who are immunocompetent. Conversely, skin and soft tissue infections, pulmonary disease and disseminated infections constitute less prevalent, yet clinically important, disease forms. Accurate identification is paramount, as differentiating NTM infections from tuberculosis (TB) remains challenging based solely on clinical symptoms, initial laboratory analyses, or standard radiological findings. This distinction is critical because treatment protocols for NTM infections differ substantially from those for tuberculosis. This narrative review offers a comprehensive and up-to-date summary of NTM infections in children. It examines the spectrum of clinical presentations and their prevalence, addresses the complexities of diagnosis and therapy, and underscores the importance of differential diagnosis against tuberculosis. Furthermore, we explore current diagnostic strategies, available therapeutic options, and the link between specific clinical syndromes and tailored management, pointing out existing knowledge gaps and suggesting priorities for future research. The absence of rapid, species-specific diagnostic tools often results in delayed initiation of targeted treatment, while overlapping clinical features with TB can lead to misdiagnosis. Therapeutic management is complicated by the necessity for prolonged drug courses, frequent occurrences of drug intolerance, limited availability of child-appropriate formulations, and the rising tide of antimicrobial resistance. Successfully tackling these issues demands enhanced surveillance, precise species-level identification, the creation of child-friendly drug formats, and the development of evidence-based treatment guidelines specifically designed for the pediatric population.

Although Cesarean section (C-section) delivery is often a necessary medical intervention, it also increases the risk of the infant developing chronic inflammatory, metabolic, and neurodevelopmental disorders. The association of C-section with the development of these conditions is thought to be partially mediated by the effects of the C-section on the infant’s microbiome development and subsequent immune regulation. C-section-delivered infants acquire a different set of microbes compared with infants who are vaginally delivered. “Vaginal seeding” exposes C-section-delivered infants to the maternal vaginal microbiome directly after birth, partly replicating the microbial exposures they would have received during a vaginal delivery. Studies have shown that vaginal seeding at birth partially restores the infant microbiome towards that of a vaginally delivered infant. More recently, preliminary studies have shown a potential benefit of vaginal seeding on health outcomes. Here, we examine the evidence from observational studies and randomized controlled trials that have evaluated microbiome restoration after C-section, and we discuss new research assessing the potential impact of vaginal seeding on immune, metabolic, and neurodevelopmental outcomes and the underlying mechanisms. Collectively, we review the potential health benefits, safety risks, regulatory implications, and future directions for the use of vaginal seeding in infants delivered by C-section. Full article
