Numerous disorders present with vesiculopustular eruptions in the neonatal period, ranging from benign to life-threatening. Accurate and prompt diagnosis is imperative to avoid unnecessary testing and treatment for benign eruptions, while allowing for adequate treatment of potentially fatal disorders. In this review, we highlight several rare blistering diseases of the newborn. A diagnostic approach is outlined to provide clinicians with a framework for approaching a neonate with vesicles, pustules, or ulcers. Autoinflammatory disorders are rare genetic defects that result in inflammation in the absence of an infectious or autoimmune disease. Although very rare, these disorders can occur in the perinatal period, and recognizing their presentation is important because there are often long-term complications and effective targeted therapies for these disorders. Most of these disorders present with rash, fevers, and laboratory evidence of inflammation. Importantly, these disorders can now be separated into their pathophysiologic mechanisms of action, which can also guide therapies. The article reviews the different mechanisms of autoinflammatory disorders and highlights those disorders that can present in the newborn period. Neonatal acute liver failure (NALF) is a rare disease with a few known primary causes gestational alloimmune liver disease (GALD), viral infections, metabolic diseases, and ischemic injury. Many cases still do not have a known cause. Laboratory evaluation may suggest a diagnosis. Most of the known causes have disease-specific treatments that improve outcomes. Survival is improving with better knowledge about and treatment options for GALD; however, overall mortality for NALF is still 24%. Liver transplant remains an important option for neonates with an indeterminate cause of NALF and those who do not respond to established treatments. The congenital muscular dystrophies and congenital myopathies are a heterogenous group of diseases with a wide variety of presentations and outcomes. buy Bobcat339 With the growing understanding of genetic involvement, and developing therapies, having a genetically confirmed diagnosis with phenotype correlation is essential. To achieve this, a structured approach is warranted to each child to ensure that mimickers are excluded. By structuring the evaluation appropriately, the clinician can help expedite the evaluation of these infants in a cost-effective manner. Understanding the pitfalls of each step of testing will allow the clinician to better understand variants in presentation and avoid cognitive errors in the process. Neonatal appendicitis is a rare disease with a high mortality rate. Appendicitis is difficult to diagnose in neonatal and infant populations because it mimics other more common conditions in these age groups. Furthermore, signs and symptoms of appendicitis are often nonspecific in nonverbal patients and a high index of suspicion is necessary to initiate the appropriate diagnostic work-up. The keys to successful management of appendicitis in infants include keeping the diagnosis on the differential in the setting of unexplained intra-abdominal sepsis, following a diagnostic algorithm in the work-up of infant abdominal pathology, and performing appendectomy once the diagnosis is confirmed. Heterotaxy is a generalized term for patients who have an abnormality of laterality that cannot be described as situs inversus. Infants with heterotaxy can have significant anatomic and medical complexity and require personalized, specialized care, including comprehensive anatomic assessment. Common and rare anatomic findings are reviewed by system to help guide a thorough phenotypic evaluation. General care guidelines and considerations unique to this patient population are included. Future directions for this unique patient population, particularly in light of improved neonatal survival, are discussed. Metabolic disorders are disruptions in nutrient metabolism or basic cellular processes that can result in severe neonatal crisis. Basic laboratory findings may reveal hypoglycemia, acidosis, or hyperammonemia, but may also be normal even in infants with severe metabolic decompensation. Breast milk or milk-based formulas often contain the nutrient that precipitates the metabolic crisis and may need to be held during acute illness. Instead, infants with suspected metabolic disorders should be administered a high glucose infusion rate with isotonic fluids to reverse catabolism. Combined advanced biochemical and molecular testing is often needed to identify specific metabolic disorders and guide ongoing treatment. Dysmorphology is the practice of defining the morphologic phenotype of syndromic disorders. Genomic sequencing has advanced our understanding of human variation and molecular dysmorphology has evolved in response to the science of relating embryologic developmental implications of abnormal gene signaling pathways to the resultant phenotypic presentation. Machine learning has enabled the application of deep convoluted neural networks to recognize the comparative likeness of these phenotypes relative to the causal genotype or disrupted gene pathway. Anemia in the newborn period can be a diagnostic challenge. This article explores the diagnosis, work-up, and differential diagnosis of anemia in this patient population with a focus on anemia that is not related to blood loss or immune-mediated conditions (isoimmune hemolysis). Mitochondrial disorders present in a myriad of ways, which causes them to be included in the differential diagnosis for many patients with undiagnosed disease. A subset of mitochondrial disorders are caused by intrinsic defects in the mitochondrial replication machinery, leading to loss of cellular mitochondrial content over time. The diagnosis of mitochondrial disease is complex. Several best-practice guides are available that enable a higher likelihood of detecting a mitochondrial disorder. The application of genomic sequencing and advanced physiologic analysis of the electron transport chain can offer more definitive evidence of mitochondrial dysfunction. Nonimmune hydrops fetalis (NIHF) historically has been considered a lethal fetal condition. Understanding NIHF to be a symptom or an end-stage status of a variety of fetal conditions, along with improved fetal diagnostics and interventions, has changed the landscape for at least some fetuses. Understanding the pathophysiologic mechanisms has led to the development of diagnostic algorithms, improved understanding of cause, and therefore fetal or neonatal treatments. Multidisciplinary counseling and shared decision making are critical to supporting families through pregnancy decisions, potential fetal therapeutic interventions, neonatal management decisions, and at times accepting or transitioning to palliative care. Critically ill neonates experience high rates of morbidity and mortality. Major diagnostic errors are identified in up to 20% of autopsied neonatal intensive care unit deaths. Neonates with undiagnosed or rare congenital disorders may mimic critically ill neonates with more common acquired conditions. The context of the diagnostic evaluation can introduce unique biases that increase the likelihood of diagnostic error. Herein is presented a framework for understanding diagnostic errors in perinatal medicine, and individual, team, and systems-based solutions for improving diagnosis learned through the implementation and administration of an undiagnosed and rare disease program. Macrophages are one of the key immune cells within the tumor microenvironment that encourage the growth of tumors at the primary site as well as contributing to all parts of the metastatic cascade. Although it is possible to isolate macrophages directly from the tumor, this can be a laborious process and due to their plasticity, it is not possible to maintain their in vivo phenotype in vitro. For this reason, differentiating macrophages from bone marrow is an attractive alternative. Here we present robust methods to study in vitro derived macrophages including (i) the isolation and generation of macrophages from bone marrow, (ii) differentiation/characterization of classically activated, alternatively activated and tumor-conditioned macrophages, as well as (iii) in vitro co-culturing assays for tumor cell-macrophage interaction/transmigration. © 2020 Elsevier Inc. All rights reserved.The intestinal tract is home to trillions of microbes that make up the gut microbiota and is a major source of environmental antigens that can be derived from food, commensal microorganisms, and potential pathogens. Amidst this complex environment, myeloid cells, including macrophages (MPs) and dendritic cells (DCs), are key immunological sentinels that locally maintain both tissue and immune homeostasis. Recent research has revealed substantial functional and developmental heterogeneity within the intestinal DC and MP compartments, with evidence pointing to their regulation by the microbiota. DCs are classically divided into three subsets based on their CD103 and CD11b expression CD103+CD11b-(XCR1+) cDC1s, CD103+CD11b+ cDC2s, and CD103-CD11b+ cDC2s. Meanwhile, mature gut MPs have recently been classified by their expression of Tim-4 and CD4 into a long-lived, self-maintaining Tim-4+CD4+ population and short-lived, monocyte-derived Tim-4-CD4+ and Tim-4-CD4- populations. In this chapter, we provide experimental procedures to classify and isolate these myeloid subsets from the murine intestinal lamina propria for functional characterization. © 2020 Elsevier Inc. All rights reserved.Dendritic cells have been widely investigated in cancer immunotherapy clinical trials for the last two decades mainly due to their robust ability to elicit an adaptive anticancer immune response of the cellular and humoral types. Immature DCs can be easily loaded with desired antigens. However, to become efficient antigen-presenting cells, DCs must first undergo a process of maturation. Protocols for the generation of DCs for use in cancer immunotherapy, including the generation of a large number of immature DCs for antigen pulsing and the selection of a well-defined immunostimulatory agent to achieve complete and reproducible maturation, which is a crucial step for further stimulation of T cell activation, must carefully consider the characteristics of DC physiology. In this report, we provided a detailed protocol for DC generation, pulsation and activation with the subsequent induction of T cell-specific immune responses. © 2020 Elsevier Inc. All rights reserved.Dendritic cells (DCs) are professional antigen-presenting cells, which are optimal for the priming of a T cell response against pathogens and tumors. Therefore, many efforts are made to develop therapeutic cancer vaccines which preferentially target the antigen to DC subsets. To this aim, we developed two types of recombinant fusion proteins, which favor antigen delivery to pro-inflammatory DCs as well as the crosstalk between specialized subpopulations of DCs. The first approach combines peptide/CpG vaccination with the recruitment of iNKT cells to the tumor site via CD1d-antitumor scFv fusion proteins. The second approach is targeting the tumor antigen to cross-presenting Xcr1+ DCs via a fusion protein made of Xcl1 fused to a synthetic long peptide followed by an IgG1 Fc fragment. Both strategies allow a potent tumor-specific CD8 T cell response associated with tumor regression or tumor growth delay depending on the model. In the case of iNKT cell activation, the strategy relies on a strong IL-12 release by splenic DCs, while in the second case, the T cell response is strictly dependent on the presence of Xcr1+ cross-presenting DCs.
