[PMID: 36335759 DOI: 10.1016/j.ijporl.2022.111373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 10/22/2022] [Accepted: 10/30/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE People with 22q11.2 deletion syndrome (22q11DS) can present with a wide variety of findings. Various airway anomalies have been described intermittently within this syndrome, but this feature has not been extensively investigated. Increased provider awareness of these findings may help guide clinical decision-making and improve overall patient outcomes. The objectives of this review are to identify the types of airway anomalies in 22q11DS and the prevalence of airway anomalies within symptomatic individuals. METHODS PubMed/MEDLINE, Cochrane Library, and EMBASE databases were searched in February 2022 for all available articles. Search terms included those that described 22q11DS or one of its synonymous conditions AND those that described airway anatomy and anomalies. The term airway anomaly was defined as any structural aberration in the conductive airway from the oral or nasal vestibule region to the mainstem bronchus. Studies were screened by two authors. A review of references was conducted. Eligible manuscripts underwent full-text review for quality appraisal and data extraction. RESULTS From a total of 909 unique manuscripts, 58 studies were selected, describing 328 people. The prevalence of airway anomaly diagnosis within symptomatic individuals ranged from 14% to 74%. Twenty-two unique airway anomalies were described. Laryngeal web was the most frequently described anomaly, followed by airway malacia and subglottic stenosis. Laryngeal web was 40% sensitive for suggesting a diagnosis of 22q11DS. Among affected individuals, as many as 46% had multiple concomitant airway anomalies. Aside from respiratory symptoms, other features that prompted airway evaluation included difficult intubation or failed extubation. CONCLUSION The findings within this review support the notion that a wide variety of airway anomalies may be seen in people with 22q11DS and that these findings have been discovered frequently in those with airway symptoms. Providers should maintain a low threshold to perform an airway examination in those with 22q11DS, especially when airway symptoms are present.

Abstract
22q11.2 deletion syndrome (22q11DS) is the most common microdeletion in humans. There have been few studies assessing the impact of this condition on the family and no previous studies conducted on unaffected siblings of children with 22q11DS. The goal of this study was to determine the frequency, method, and content of information being communicated by parents to unaffected siblings about the condition and to assess unaffected siblings' knowledge of 22q11DS and perceptions of the impact of the condition on their affected sibling and themselves. Families were recruited from several 22q11DS educational and support organizations and asked to complete a single anonymous online survey. Families were eligible to participate if they had one child with 22q11DS and at least one unaffected child between the ages of 12 and 17. Survey questions were developed based on previous literature and authors' expertise with individuals with 22q11DS. Responses to quantitative and qualitative questions were analyzed to calculate frequencies and proportions and to extract themes, respectively. A total of 25 families (defined as a unit of at least one parent, one affected child, and at least one unaffected child) participated in the study. Parents shared genetic information less often as compared to behavioral and medical information. Siblings of children with 22q11DS had both positive and negative experiences in having a brother or sister with this condition. Genetic counselors can use the results of this study to develop anticipatory guidance for parents of children with 22q11DS in talking with their unaffected children about the condition.

Abstract
We assessed feeding-related developmental anomalies in the LgDel mouse model of chromosome 22q11 deletion syndrome (22q11DS), a common developmental disorder that frequently includes perinatal dysphagia – debilitating feeding, swallowing and nutrition difficulties from birth onward – within its phenotypic spectrum. LgDel pups gain significantly less weight during the first postnatal weeks, and have several signs of respiratory infections due to food aspiration. Most 22q11 genes are expressed in anlagen of craniofacial and brainstem regions critical for feeding and swallowing, and diminished expression in LgDel embryos apparently compromises development of these regions. Palate and jaw anomalies indicate divergent oro-facial morphogenesis. Altered expression and patterning of hindbrain transcriptional regulators, especially those related to retinoic acid (RA) signaling, prefigures these disruptions. Subsequently, gene expression, axon growth and sensory ganglion formation in the trigeminal (V), glossopharyngeal (IX) or vagus (X) cranial nerves (CNs) that innervate targets essential for feeding, swallowing and digestion are disrupted. Posterior CN IX and X ganglia anomalies primarily reflect diminished dosage of the 22q11DS candidate gene Tbx1. Genetic modification of RA signaling in LgDel embryos rescues the anterior CN V phenotype and returns expression levels or pattern of RA-sensitive genes to those in wild-type embryos. Thus, diminished 22q11 gene dosage, including but not limited to Tbx1, disrupts oro-facial and CN development by modifying RA-modulated anterior-posterior hindbrain differentiation. These disruptions likely contribute to dysphagia in infants and young children with 22q11DS.

Abstract
This study examines the rate of utilization of mental health services in children and adolescents with 22q11DS relative to their remarkably high rate of psychiatric disorders and behavior problems. Seventy-two children and adolescents with 22q11DS were participants; their parents completed the Diagnostic Interview Schedule for Children (DISC) and the Child Behavior Checklist (CBCL). The results indicated that 22q11DS children and adolescents have higher rates of psychopathology than the general pediatric population, with ADHD and anxiety disorders being the most common. However, among youth with 22q11DS, those with psychopathology are often no more likely to receive either pharmacological or non-pharmacological mental health care than those without a given psychiatric diagnosis. Thus, although psychopathology is fairly common in this sample, many children with 22q11DS may not be receiving needed psychiatric care. These results have significant implications for these children and their families, as well as for the health care providers who treat them. In particular, the results may suggest a need for careful screening of psychiatric disorders that are likely to affect this population as well, as making appropriate treatment recommendations to remedy childhood mental health problems. Since these children face an extraordinarily high risk of psychoses in late adolescence/adulthood, treatment of childhood psychopathology could be crucial in mitigating the risk/consequences of major psychiatric illnesses in later life.

Abstract
BACKGROUND The 22q11 deletion syndrome (22q11DS) is one of the most common multiple anomaly syndromes, with an incidence of approximately one per 4000 newborns. Although a patient may have several not too severe symptoms, the cumulative effect may be substantial disability. The aim of this study was to explore and describe parents' experiences of the diagnostic process and of being parents of a child with 22q11DS. METHODS Open, tape-recorded interviews were carried out with 12 parents. The interviews were analysed in accordance with classical grounded theory. RESULTS The analysis show that parents describe the disclosure of their child's medical diagnosis as two-sided, ambivalence between relief and sorrow, and the differences between these two aspects were related to the age of the child at time of diagnosis as well as to the problems and symptoms that had led to the diagnosis. Different strategies for handling this ambivalence are presented in the categories. CONCLUSIONS Our conclusions are that information must be individually tailored, and there is no standard format for how to describe the syndrome to the parents. After disclosure, scheduled appointments for follow-up on diagnosis-related information is essential.

Abstract
BACKGROUND 22q11 deletion syndrome (22q11DS) is one of the most common multiple anomaly syndromes, and many dentists are likely to meet patients with the syndrome. Odontological research has focused on describing and analysing conditions/concepts based on the current state of knowledge within the dental profession. Yet, these research topics are not necessarily the most important issues for the patients. AIMS To explore and describe, by use of Grounded theory, parents' experiences of oral health issues and needs for dental care in their children with 22q11DS. DESIGN Twelve parents from different regions in Sweden were interviewed. Analyses were carried out according to Grounded theory. RESULTS Parents recognised good oral health as important for the wellbeing of their children. Oral health was a concern and the parents described the fight for this as struggling in vain for good oral health in their child. CONCLUSIONS Parents not only described their children's oral health as important but also hard to gain. Thus, it is important that all patients with disabilities, regardless of whether there is a defined medical diagnosis or not, are identified and well taken care of in the dental care system.

Abstract
OBJETIVO:Realizar uma revisão dos aspectos históricos, epidemiológicos, clínicos, etiológicos e laboratoriais da síndrome de deleção 22q11.2, salientando-se a importância e as dificuldades do seu diagnóstico. FONTES DE DADOS: Pesquisa nas bases de dados Medline, Lilacs e SciELO, além da Internet e capítulos de livros em inglês, acerca de publicações feitas entre 1980 e 2008. Para isso, utilizaram-se os descritores "22q11", "DiGeorge", "Velocardiofacial" e "CATCH22". SÍNTESE DOS DADOS: A síndrome de deleção 22q11.2, também conhecida como síndrome de DiGeorge ou velocardiofacial, foi identificada no começo da década de 1990. A microdeleção 22q11.2 é considerada uma das síndromes de microdeleção genética mais frequentes em seres humanos. Caracteriza-se por um espectro fenotípico bastante amplo, com mais de 180 achados clínicos já descritos do ponto de vista físico e comportamental. Contudo, nenhum achado é patognomônico ou mesmo obrigatório. A maioria dos pacientes apresenta uma deleção pequena, detectada somente por técnicas de genética molecular, como a hibridização in situ fluorescente. Apresenta padrão de herança autossômico dominante, ou seja, indivíduos acometidos apresentam um risco de 50% de transmiti-la a seus filhos. CONCLUSÕES: Pacientes com a síndrome de deleção 22q11.2 frequentemente necessitam, ao longo de suas vidas, de um grande número de intervenções médicas e hospitalizações. O diagnóstico precoce é fundamental para a adequada avaliação e manejo clínico dos indivíduos e seus familiares.

Abstract
Infections with adenoviruses are a common problem in the pediatric population. Normally asymptomatic to mild, those infections tend to take a more severe course in immunocompromised patients. 22q11 deletion syndrome (22q11DS) represents a common genetic disorder causing immunodeficiency from thymic hypoplasia or aplasia, heart defects, a characteristic facial appearance, and velopharyngeal dysfunction. Necrotizing enterocolitis (NEC) is a frequent gastrointestinal emergency observed in neonatal intensive care units. The occurrence of NEC is more prevalent in preterm infants. However, there are cases in term infants, but usually, they are associated with predisposing disorders. In this case report, a child is presented with 22q11DS that postnatally developed NEC associated with an adenoviral infection. Although other viruses such as toroviruses or cytomegaloviruses have been implicated in the pathogenesis of NEC in preterm infants, we could not find any report in the recent medical literature describing an association between adenoviral infections, NEC, and 22q11DS in a term infant.

Abstract
OBJECTIVES The aims were to compare saliva secretion rate, buffer capacity, cariogenic bacteria, total protein, IgA, and electrolytes between patients with 22q11 deletion syndrome (22q11DS) and control subjects and to study correlations between saliva and serum levels of IgA and electrolytes in 22q11DS patients. STUDY DESIGN Twenty-nine consecutive 22q11DS patients (mean age 12.6 years) and matched healthy control subjects were clinically examined, and stimulated saliva samples were collected. RESULTS Patients with 22q11DS had impaired salivary secretion rate (P < .01) and buffer capacity (P < .05), higher numbers of cariogenic bacteria (P < .01), increased saliva protein concentrations (P < .001), and reduced output of electrolytes (P < .001-.05) compared with control subjects. A correlation between concentration in serum and saliva was found only for IgA (r = .622; P < .01). CONCLUSIONS Different salivary components were affected in patients with 22q11DS, which may explain the increased caries risk seen in these patients.

Abstract
Patients with 22q11 deletion syndrome have many and complex medical problems, including hypocalcemia and/or hypoparathyroidism. Odontological findings include enamel aberrations in both dentitions. In order to describe enamel morphology, chemical composition in primary teeth, and to investigate the relationship between medical history and morphological appearance, dental enamel was investigated in 38 exfoliated primary teeth from 15 children and adolescents. Morphology was studied by the use of a polarized light microscope, microradiography, scanning electron microscopy, X-ray microanalysis, and secondary ion mass spectrometry. The morphological findings were compared with medical history. The teeth showed, in principle, a normal morphological appearance with regard to prism structure. A high frequency of aberrations, such as hypomineralization, hypoplasia and extra incremental lines, were found. The majority of the aberrations were found around the neonatal line. There was a relationship between high numbers of medical problems in the patients and enamel deviations. The result supports the hypothesis of under-reporting of both hypocalcemia and hypoparathyroidism in patients with 22q11 deletion syndrome.

Abstract
OBJECTIVE To determine if chromosome 22q11 deletion status can be predicted in fetuses with tetralogy of Fallot as regards additional phenotypic anomalies. METHODS One hundred and fifty-one consecutive fetuses with tetralogy of Fallot without or with pulmonary atresia were screened for 22q11 deletion. Additional echographic features [increased nuchal translucency (NT), intrauterine growth retardation (IUGR), polyhydramnios, extracardiac malformations, pulmonary arteries abnormalities] were noted. RESULTS Twenty-five fetuses had a 22q11 deletion (16.6%). Increased NT, polyhydramnios and IUGR were more frequent in fetuses with 22q11 deletion as well as pulmonary arterial abnormalities. When these different features were present in the same fetus with tetralogy of Fallot, 22q11 deletion can be predicted with a sensitivity of 88%. CONCLUSION Simple echographic features can help to predict 22q11 status in fetuses with tetralogy of Fallot. This may improve the efficiency of prenatal screening for this defect.

Abstract
DiGeorge syndrome is characterized by conotruncal cardiac defects, hypocalcemia, and a hypoplastic thymus. Many, but not all, patients have a heterozygous deletion of chromosome 22q11.2. In its most severe form, it represents a devastating syndrome with high mortality. Patients with severe immunodeficiency are candidates for a thymic transplant or a fully matched bone marrow transplant. Fortunately, the majority of patients with either DiGeorge syndrome or chromosome 22q11.2 deletion syndrome have a mild to moderate immunodeficiency. These patients may develop recurrent infections or autoimmune disease.
