    Abstract Aim: To develop a feeding scale for parents/care givers of individuals of all ages with genetic syndromes experiencing extensive feeding and swallowing problems. Second, to assess its validity and reliability in CHARGE syndrome.
    Methods: The new Feeding Assessment Scale (FAS) was adapted from a scale for children who need prolonged tube feeding (Paediatric Assessment Scale for Severe Feeding Problems, PASSFP). Ten parents piloted the new scale before it was sent out with the PASSFP and feeding history questions. A subset completed the new scale again 4-8 weeks later.
    Results: One hundred parents of individuals with CHARGE syndrome participated from around the world. The new scale had good construct validity, with a significant effect for an increased number of feeding risk factors having higher scale scores (P < 0.001). Face validity was high, as scores significantly differed between individuals whose parents identified their feeding difficulties as very mild, mild, moderate, severe and very severe (P < 0.001). Test-retest reliability (r = 0.94, P < 0.001) and internal consistency (Cronbach's alpha 0.91) were both high. There was significant convergent validity between the new scale and the PASSFP (r = -0.79, P < 0.001).
    Conclusions: This new tool is reliable and valid for parents/care givers of individuals with CHARGE syndrome. It can be used to assess the current severity of feeding difficulties and to track progress before and after treatment. It expands upon previous existing tools in that it can be used in both individuals who are not tube fed, as well as in those who are, as well as across the life-span.

    Abstract CHARGE syndrome is an autosomal dominant genetic condition that is primarily diagnosed based on clinical features, with genetic testing available for confirmation. The CHARGE mnemonic stands for some of the common characteristics: coloboma, heart defects, atresia/stenosis of the choanae, retardation of growth/development, genitourinary anomalies, and ear abnormalities (CHARGE). However, many of the common clinical features are not captured by this mnemonic, including cranial nerve dysfunction, considered by some to be one of the major diagnostic criteria. Over 90% of individuals experience feeding and gastrointestinal dysfunction, which carries great morbidity and mortality. The aim of this review is to examine the nature of gastrointestinal (GI) symptoms and feeding difficulties in CHARGE syndrome, focusing on their underlying pathology, associated investigations, and available treatment options. We also provide information on available tools (for parents, clinicians, and researchers) that are important additions to the lifelong healthcare management of every individual with CHARGE syndrome. We review how cranial nerve dysfunction is one of the most important characteristics underlying the pervasive GI and feeding dysfunction, and discuss the need for future research on gut innervation and motility in this genetic disorder.

    Abstract Factitious disorder imposed on another (FDIA) and malingering by proxy (MAL-BP) are two forms of underreported child maltreatment that should remain on physicians' differential. This case of a 2-year-old boy, which spans 6 years, reveals the complexity in and difficulties with diagnosis. Key features include the patient's mother using advanced medical jargon to report multiple disconnected concerns and visits to numerous providers. As a result, the patient underwent many investigations which often revealed normal findings. FDIA was suspected by the paediatrician, especially following corroboration with the child's day care and past primary health care provider. This case demonstrates the possible overlap in diagnoses, which are characterized by a lack of consistent presentation and deceitful caregivers, often complicated by true underlying illness. The authors use clinical experience and limited existing literature to empower paediatricians to confidently diagnose and report FDIA and MAL-BP to limit future harm to children.

    Abstract CHARGE syndrome typically results from mutations in the gene encoding chromodomain helicase DNA-binding protein 7 (CHD7). CHD7 is involved in regulating neural crest development, which gives rise to tissues of the skull/face and the autonomic nervous system (ANS). Individuals with CHARGE syndrome are frequently born with anomalies requiring multiple surgeries and often experience adverse events post-anesthesia, including oxygen desaturations, decreased respiratory rates, and heart rate abnormalities. Central congenital hypoventilation syndrome (CCHS) affects ANS components that regulate breathing. Its hallmark feature is hypoventilation during sleep, clinically resembling observations in anesthetized CHARGE patients. Loss of PHOX2B (paired-like homeobox 2b) underlies CCHS. Employing a chd7-null zebrafish model, we investigated physiologic responses to anesthesia and compared these to loss of phox2b. Heart rates were lower in chd7 mutants compared to the wild-type. Exposure to tricaine, a zebrafish anesthetic/muscle relaxant, revealed that chd7 mutants took longer to become anesthetized, with higher respiratory rates during recovery. chd7 mutant larvae demonstrated unique phox2ba expression patterns. The knockdown of phox2ba reduced larval heart rates similar to chd7 mutants. chd7 mutant fish are a valuable preclinical model to investigate anesthesia in CHARGE syndrome and reveal a novel functional link between CHARGE syndrome and CCHS.

    Abstract CHARGE syndrome is a genetic disorder that affects multiple organ and sensory systems. Cranial nerve involvement is one of the key clinical diagnostic criteria. We present the case of an 8-year-old girl with CHARGE syndrome, associated right-sided facial palsy, and chronic severe migraines, that were intractable to medical treatment. At age 6, onabotulinum toxin A was used to weaken the contralateral non-paralyzed side of her face to address her stigmatizing asymmetry. Onabotulinum toxin A chemodenervation was performed on the left lower lip depressors to relax the muscles and improve left lower lip position. Coincidentally, it was noted that with these treatments, migraine symptoms resolved. As the chemodenervation subsided over the next 3-4 months, the severe migraines returned. Continued treatment with onabotulinum toxin A injections every 3 months has resulted in ongoing improvements in facial symmetry and migraine control. Onabotulinum toxin A is a well-known treatment of chronic migraine. Injections are usually directed to the occipitalis, frontalis, and corrugator muscles. The literature has no reports of injections to the lower lip depressors as a useful therapy for migraine, making the results from this case unique.

    Abstract Feeding and swallowing difficulties are common among individuals with CHARGE syndrome. Many children require gastrostomy tube feeding in their early years and often undergo a delay in feeding and oral-motor skill development. There is little information available on adults with CHARGE syndrome, and the feeding difficulties they face. The present case describes newly emerging mouth over-stuffing feeding behaviors and feeding difficulties in a 33-year-old adult with CHARGE syndrome who had not undergone feeding therapy since childhood.

    Abstract Background: Little is known about how Canadian medical schools teach paediatric clinical skills (history and physical exam) to preclerkship students, or its cost to the institutions.
    Methods: Clinical skills program directors from all 17 Canadian medical schools were contacted to complete a questionnaire focused on teaching methods, and barriers/strengths of their Preclerkship Paediatric Clinical Skills program.
    Results: Seventeen schools (100% response rate) participated. Seven schools (41%) do not introduce paediatric clinical skills until the second year of medicine. Half of the schools (53%) dedicate <10 total hours to preclerkship paediatric clinical skills. Fifty-nine per cent have ≤6 total hours of hands-on paediatric patient interaction (real or simulated). Medical students were least likely to be exposed to the infant age group (age 1 to 24 months). Twelve schools (71%) used simulated parent/child dyads. The most significant barriers identified by programs were limited time for sessions and patient availability. We describe one sample medical school's simulated parent/paediatric patient program where every student has hands-on learning with paediatric patients of all ages (program cost $938/student).
    Discussion: This study is the first to summarize Canadian preclerkship paediatric clinical skills programs, among which there is great variability and commonly experienced barriers. Many students are not being exposed to all age groups of paediatric patients before their clerkship years. Medical schools can use this information to strengthen this important and challenging aspect of the curriculum, while being mindful of its fiscal implications.
