Abstract
Congenital lobar emphysema (CLE)/congenital alveolar overdistension/congenital lobar overinflation or infantile lobar emphysema is a rare developmental anomaly of the lower respiratory tract which is characterised by hyperinflation of one or more of the pulmonary lobes. Histopathology may be variable, which may show abnormality in the cartilage, granulation tissue, mucosal folds, etc. We report a rare underlying histopathology in a preterm neonate with CLE. This entity referred to as pulmonary interstitial glycogenosis (PIG) is a group of heterogeneous lung disease affecting the lung parenchyma and is characterised by the presence of glycogen laden cells in the lung interstitium. This impairs the gas exchange and typically manifest as tachypnoea, retractions, hypoxia and increased respiratory support. Our case report highlights the association of CLE and PIG and a review of literature. One should always have a detailed histopathology in children presenting with CLE to rule out PIG.

Interstitial Lung Disease in Children: “Specific Conditions of Undefined Etiology” Becoming Clearer. CHILDREN 2022; 9:children9111744. [PMID: 36421193 PMCID: PMC9688624 DOI: 10.3390/children9111744] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 11/07/2022] [Accepted: 11/11/2022] [Indexed: 11/16/2022]
Abstract
Background: Children’s interstitial lung disease (chILD) is a rare group of pediatric lung diseases affecting the lung interstitium diffusely. In this work, we focused our attention on a specific infant group of chILD, also known as “specific conditions of undefined aetiology”, including pulmonary interstitial glycogenosis (PIG) and neuroendocrine cell hyperplasia of infancy (NEHI). Methods: PubMed was searched to conduct this narrative review. We searched for articles in English using the following keywords: (1) neuroendocrine cell hyperplasia of infancy; (2) NEHI; (3) pulmonary interstitial glycogenosis; (4) PIG; (5) chILD. Results: An increasing interest and insight into these two conditions have been reported. The updated literature suggests that it is possible to look at these disorders as a continuum of diseases, rather than two different entities, since they share a pulmonary dysmaturity. Conclusions: NEHI and PIG are featured by dysmaturity of airway development and consequent respiratory distress. Understanding the underlying pathogenic mechanisms would lead to identifying new targeted therapies to ameliorate the mortality and morbidity of these rare conditions.

Abstract
Interstitial lung diseases in children are a diverse group in terms of etiology and pathogenesis. With advances in genetic testing, mutations in surfactant protein have now been identified as the etiology for childhood interstitial lung disease of variable onset and severity, ranging from fatal acute respiratory distress syndrome (RDS) in neonates to chronic lung disease in adults. We presented an 11-month-old girl with surfactant protein C deficiency and secondary pulmonary hypertension, successfully treated with hydroxychloroquine, and provided a detailed discussion of the clinical and diagnostic approach and management.

Abstract
Children's interstitial lung disease (chILD) encompasses a wide and heterogeneous spectrum of diseases substantially different from that of adults. Established classification systems divide chILD into conditions more prevalent in infancy and other conditions occurring at any age. This categorisation is based on a multidisciplinary approach including clinical, radiological, genetic and histological findings. The diagnostic evaluation may include lung biopsies if other diagnostic approaches failed to identify a precise chILD entity, or if severe or refractory respiratory distress of unknown cause is present. As the majority of children will be evaluated and diagnosed outside of specialist centres, this review summarises relevant clinical, genetic and histological findings of chILD to provide assistance in clinical assessment and rational diagnostics. ILD of childhood is comparable by name only to lung disease in adults. A dedicated interdisciplinary team is required to achieve the best possible outcome. This review summarises the current clinicopathological criteria and associated genetic alterations.https://bit.ly/3mpxI3b

Abstract
Congenital interstitial lung diseases can affect both adults and children. Pediatric congenital interstitial lung diseases generally carry high risk for morbidly and mortality and include congenital alveolar capillary dysplasia with misalignment of pulmonary veins, congenital alveolar dysplasia, acinar dysplasia, congenital pulmonary lymphangiectasis, diffuse pulmonary lymphangiomatosis, neuroendocrine cell hyperplasia of infancy, pulmonary hemosiderosis, pulmonary alveolar proteinosis, and pulmonary interstitial glycogenosis. Given their usual non-specific clinical presentation, they are frequently misdiagnosed and recognized late, particularly in children who have been apparently healthy for several years (eg, diffuse pulmonary lymphangiomatosis). Some diseases have a very poor prognosis, whereas others have a benign course with appropriate treatment. The current manuscript reviews congenital interstitial lung diseases that typically affect neonates and young children and may be encountered by the pediatric anesthesiologist.

Abstract
OBJECTIVE To analyze the etiology of chest diffuse radiological changes (DRC) in children older than 2 years. METHODS A retrospective study was conducted on a primary cohort of children with DRC underwent high resolution computed tomography (HRCT). RESULTS DRC mainly included bronchial wall thickening, interlobular septal thickening, pleural thickening, ground glass opacity, mosaic perfusion, reticular & linear opacities, nodular opacity, and tree-in-bud. Of the identified 457 children with DRC, 83 of children older than 2 years with DRC were included in the present study. Ground glass opacity (53, 63.9%) and reticular & linear opacities (44, 53.0%) were frequently identified findings of HRCT, and no tree-in-bud pattern was observed. By contrast, among children with DRC by M. pneumoniae (n = 64), bronchial wall thickening (33, 51.6%), and mosaic perfusion (17, 26.6%) were common patterns of HRCT in addition to ground glass opacity (36, 56.3%). Most of etiologies were connective tissue disease (24, 28.9%), followed by diffuse alveolar hemorrhage syndrome (9, 10.8%), Langerhans cell histiocytosis (7, 8.4%), and recurrent aspiration (6, 7.2%). CONCLUSIONS This study adds further insights into the role of HRCT in diagnosing childhood interstitial lung diseases, indirectly reflecting disease compositions.

Abstract
Surfactant protein C (SP-C) is a hydrophobic lipoprotein necessary for lowering alveolar surface tension and lung defense mechanisms. Defects in its function due to genetic mutations in the SFTPC gene have been increasingly identified in patients presenting with childhood interstitial lung disease. SFTPC mutations are inherited in an autosomal dominant pattern with reduced penetration and variable expressivity, although de novo mutations have also been documented. In this article, we present the case of an oxygen-dependent 13-year-old male with interstitial lung disease and severe pulmonary hypertension. Genetic analysis and lung biopsy confirmed the diagnosis of SP-C deficiency with the rare heterozygous mutation IVS4+2. To our knowledge, this is the first documented case of SP-C deficiency in the Puerto Rican population and the second worldwide with the IVS4+2 genetic mutation.
