PURPOSE: Mesenchymal stem cells (MSCs) represent a promising source for stem cell therapies in numerous diseases, including pediatric respiratory system diseases. Characterized by low immunogenicity, high anti-inflammatory, and immunoregulatory features, MSCs demonstrated an excellent therapeutic profile in numerous in vitro and preclinical models. MSCs reside in a specialized physiologic microenvironment, characterized by a unique combination of biophysical, biochemical, and cellular properties...

Background In the palliative pathway of single-ventricle physiology, lymphatic abnormalities on T2-weighted magnetic resonance imaging have been shown after the Glenn operation. It is believed that postsurgical hemodynamic changes contribute to the lymphatic changes.However, little is known about how early these abnormalities occur. Our purpose was to determine if lymphatic abnormalities occur as early as before the Glenn operation. Methods and Results We retrospectively reviewed patients with single-ventricle physiology and a T2-weighted magnetic resonance imaging scan before their Glenn operation (superior cavopulmonary connection) at The Children's Hospital of Philadelphia from 2012 to 2022...

Childhood interstitial lung disease (chILD) is a collective term for a group of rare lung disorders of heterogeneous origin. Surfactant dysfunction disorders are a cause of chILD with onset during the neonatal period and infancy. Clinical signs of tachypnea and hypoxemia are nonspecific and usually caused by common conditions like lower respiratory tract infections. We report on a full-term male newborn who was readmitted to the hospital at 7 days of age with marked tachypnea and poor feeding during the respiratory syncytial virus season...

Interstitial and diffuse lung diseases in children constitute a range of congenital and acquired disorders. These disorders present with signs and symptoms of respiratory disease accompanied by diffuse radiographic changes. In many cases, radiographic findings are nonspecific, while in other disorders, chest computed tomography (CT) is diagnostic in the appropriate context. Regardless, chest imaging remains central in the evaluation of the patient with suspected childhood interstitial lung disease (chILD)...

Congenital malformations are defined as single or multiple defects of the morphogenesis of organs or body parts, identifiable during intrauterine life or at birth. With recent advances in prenatal detection of congenital malformations, many of these disorders can be identified early on a routine fetal ultrasound. The aim of the present systematic review is to systematize the current knowledge about the mode of delivery in pregnancies complicated by fetal anomalies. The databases Medline and Ebsco were searched from 2002 to 2022...

BACKGROUND: Congenital absence of the pericardium (CAP) is rare in clinical practice, the symptoms vary among patients, and most doctors do not have enough knowledge of the condition. Most reported CAP cases are incidental findings. Therefore, this case report aimed to present a rare case of left partial CAP that presented with non-specific, possibly cardiac-related symptoms. CASE PRESENTATION: The patient, male, 56 years old, Asian, was admitted on March 2, 2021...

BACKGROUND Agnathia-otocephaly complex (AOC) is a rare congenital malformation due to a first-branch arch disorder and has been considered lethal. However, milder variants of the isolated type of AOC have been reported as nonlethal. The ex-utero intrapartum treatment (EXIT) procedure is basically indicated for a fetus with a high risk of airway obstruction immediately after birth; it is not indicated for all AOC cases but is chosen to treat cases until the airway can be evaluated to achieve a better prognosis...

BACKGROUND: Pathologic characterization of pulmonary complications following hematopoietic stem cell transplantation (HSCT) is limited. We describe lung findings in pediatric patients who died following HSCT and attempt to identify potential clinical associations. METHODS: Pathology databases at Texas Children's Hospital and the Children's Hospital of Philadelphia were queried (2013-2018 CHOP and 2017-2018 TCH). Electronic medical records and slides were reviewed...

Congenital alpha-1 antitrypsin deficiency (AATD) is a rare inherited disorder caused by the mutation of the SERPINA1 gene on chromosome 14. At pulmonary level, AAT deficiency leads to an increased risk of chronic obstructive pulmonary disease (COPD) and emphysema, starting from the third-fourth decade of life. At hepatic level, some variants of the allelic, in particular PI*Z, cause a conformational change of the AAT molecule, which polymerizes within the hepatocytes. Excessive hepatic accumulation of these abnormal molecules can lead to liver disease in both adults and children, with clinical presentation ranging from cholestatic jaundice in the newborn to abnormal blood indices of liver function in children and adults, up to fatty liver, cirrhosis and hepatocarcinoma...

BACKGROUND: Vascular rings, including right aortic arch with aberrant left subclavian artery (RAA-ALSCA), double aortic arch (DAA) and pulmonary artery sling (PAS), are congenital anomalies that may cause airway and oesophageal compression. As prenatal detection has improved, literature comparing clinical outcomes of antenatally versus postnatally diagnosed cases continues to emerge. The aim is to define a statewide tertiary paediatric institution's clinical profile and outcomes of prenatal versus postnatally diagnosed isolated vascular rings...

Hepatocyte nuclear factor-1 beta (HNF1B) gene is predominantly expressed in the liver, kidney, lung, genitourinary tract, and pancreas. It is an important transcription factor that regulates pancreas development. Mutation or absence of this gene is rare and can cause incomplete pancreatic development known as the agenesis of the dorsal pancreas. This rare genetic abnormality is associated with other disorders like maturity-onset diabetes of the young, abnormal liver function tests, genitourinary tract malformation, pancreatitis, and renal cysts...

Lung cancer (LC) is one of the most common causes of death worldwide. The identification of oncogene-addicted driving mutations suitable for targeted therapy has improved clinical outcomes in advanced diseases. Clinical trials, on the other hand, rarely involve vulnerable groups such as pregnant women. We report a 37-year-old woman with advanced non-small cell lung cancer (NSCLC) harboring an exon 19 deletion of EGFR treated with afatinib. After the initial treatment, the patient achieved a complete response and had an unplanned pregnancy...

Neonatal lung and heart diseases, albeit rare, can result in poor quality of life, often require long-term management and/or organ transplantation. For example, Congenital Heart Disease (CHD) is one of the most common type of congenital disabilities, affecting nearly 1% of the newborns, and has complex and multifactorial causes, including genetic predisposition and environmental influences. To develop new strategies for heart and lung regeneration in CHD and neonatal lung disease, human induced pluripotent stem cells (hiPSCs) provide a unique and personalized platform for future cell replacement therapy and high-throughput drug screening...

Congenital diaphragmatic hernia (CDH) is a severe birth anomaly where a defect in the diaphragm allows abdominal organs to herniate into the chest with compression of the intrathoracic structures, specifically the lungs and heart. Pulmonary and left ventricular hypoplasia result in respiratory insufficiency after birth with disordered transition and persistent pulmonary hypertension of the newborn (PPHN). As a result, infants need immediate intervention after birth to support the transition. Delayed cord clamping (DCC) is recommended for all healthy newborns and improves outcomes in infants born preterm and in infants with congenital heart disease; however, DCC may not be feasible in newborns needing immediate intervention after birth...

INTRODUCTION: Alveolar Capillary Dysplasia with Misaligned Pulmonary Veins (ACDMPV) is a fatal congenital disease resulting from a pulmonary vascular endothelial deficiency of FOXF1, producing abnormal morphogenesis of alveolar capillaries, malpositioned pulmonary veins and disordered development of lung lobes. Affected neonates suffer from cyanosis, severe breathing insufficiency, pulmonary hypertension, and death typically within days to weeks after birth. Currently, no treatment exists for ACDMPV, although recent murine research in the Kalinichenko lab demonstrates nanoparticle delivery improves survival and reconstitutes normal alveolar-capillary architecture...

Each year, 2.4 million children die within their first month of life. Child Health and Mortality Prevention Surveillance (CHAMPS) established in 7 countries aims to generate accurate data on why such deaths occur and inform prevention strategies. Neonatal deaths that occurred between December 2016 and December 2021 were investigated with MITS within 24-72 hours of death. Testing included blood, cerebrospinal fluid and lung cultures, multi-pathogen PCR on blood, CSF, nasopharyngeal swabs and lung tissue, and histopathology examination of lung, liver and brain...

BACKGROUND: There is overlap between movement disorders and neuroendocrine abnormalities. OBJECTIVES AND METHODS: To provide a systematic review on the association of thyroid dysfunction and movement disorders. Thyroid physiological function and classical thyroid disorders highlighting typical and atypical manifestations including movement disorders, as well as diagnostic procedures, and treatments are discussed. RESULTS: Hypothyroidism may be associated with hypokinetic and hyperkinetic disorders...

Toxoplasmosis is a zoonotic protozoal disease characterized by a chronic course, polymorphism of clinical manifestations, predominant damage to the central nervous system, organs of vision, liver and lungs. The causative agent of the disease is the obligate intracellular parasite Toxoplasma gondii, which circulates widely in the external environment and has a large circle of intermediate hosts. Toxoplasmosis is classified by the method of infection (congenital or acquired), by pathogenesis (acute or chronic), by manifestation (latent or with the manifestation of symptoms)...

Classic alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is a rare congenital lung disorder presenting in the early neonatal period with refractory hypoxemic respiratory failure and pulmonary hypertension. No curative treatment is currently available. Although definitive diagnosis is obtained by histology, lung biopsy is often challenging in unstable, critically ill neonates. Molecular diagnosis has been achieved with chromosomal microarray and targeted gene sequencing; however, each of these modalities can be limited by turnaround time, coverage of the genome, and inability to detect all pathogenic variant types for ACDMPV...
