Persistent omphalomesenteric duct in an infant with trisomy 21.

We present the case of a term newborn with trisomy 21 who presented to the paediatric emergency department with periumbilical flare and green-brown discharge from a clamped umbilical cord, initially suspected to be omphalitis. However, it was noticed later, that when the infant strained or cried, a thick, bubbling and offensive green-brown discharge came out of the clamped umbilical cord with umbilical flatus. An ultrasound abdomen and umbilical cord confirmed the presence of a persistent omphalomesenteric duct (POMD). He was then transferred to the paediatric surgical unit. There, he underwent a laparotomy and surgical resection of the POMD and was discharged home 2 days later.

Neurodevelopmental impairments in children with septo-optic dysplasia spectrum conditions: a systematic review.

BACKGROUND: Septo-optic dysplasia (SOD) is a rare condition diagnosed in children with two or more of the following: hypopituitarism, midline brain abnormalities, and optic nerve hypoplasia. Children with SOD experience varied visual impairment and endocrine dysfunction. Autistic-like behaviours have been reported; however, their nature and prevalence remain to be fully understood. The present systematic review aimed to explore the type and prevalence of neurodevelopmental impairments in children with SOD spectrum conditions. METHODS: The search was conducted in PubMed, EMBASE, and PsycInfo. Hand-searching reference lists of included studies was conducted. All peer-reviewed, observational studies assessing behavioural and cognitive impairments or autism spectrum disorder (ASD) symptoms in children (< 18 years) with SOD, optic nerve hypoplasia, and SOD-plus were included. Studies were excluded if they did not report standardised measures of neurodevelopmental impairments or ASD outcomes. RESULTS: From 2132 screened articles, 20 articles reporting data from a total of 479 children were included in prevalence estimates. Of 14 studies assessing cognitive-developmental outcomes, 175 of 336 (52%) children presented with intellectual disability or developmental delay. A diagnosis of ASD or clinical level of symptoms was observed in 65 of 187 (35%) children across five studies. Only five studies assessed for dysfunction across behavioural, emotional, or social domains and reported impairments in 88 of 184 (48%) of children assessed. LIMITATIONS: Importantly, high heterogeneity among the samples in relation to their neuroanatomical, endocrine, and optic nerve involvement meant that it was not possible to statistically assess the relative contribution of these confounding factors to the specific neurodevelopmental phenotype. This was further limited by the variation in study designs and behavioural assessments used across the included studies, which may have increased the risk of information bias. CONCLUSIONS: This systematic review suggests that the prevalence of neurodevelopmental impairments in children within the SOD spectrum may be high. Clinicians should therefore consider including formal assessments of ASD symptoms and neurodevelopmental impairments alongside routine care. There is, additionally, a need for further research to define and validate a standardised battery of tools that accurately identify neurodevelopmental impairments in SOD spectrum conditions, and for research to identify the likely causal mechanisms.

'Virtual neonatal crash course': quality improvement in neonatal teaching for paediatric trainees.

There are limited Foundation Programme posts with rotations in paediatrics. Many junior paediatric trainees therefore start their neonatal jobs, including a mandatory 6-month tertiary neonatal placement during Level 1 training, without prior experience. The aim of this project was to improve trainees' confidence in the practical aspects of neonatal medicine prior to their first neonatal jobs. A virtual course was delivered to paediatric trainees, on the core principles of neonatal intensive care medicine. Trainees' confidence levels in different domains of neonatology were assessed with pre- and postcourse questionnaires, showing a significant improvement in confidence following the course. Trainees' qualitative feedback was also overwhelmingly positive. Overall, there is evidently a desire for supplemental neonatal education for paediatric trainees. The long-term plan to address this is to build upon this course with a transition to face-to-face lectures paired with skills workshops for paediatric trainees in London.

A case of likely acute febrile neutrophilic dermatosis in a 17-year-old male presenting to general paediatrics.

We present the case of a 17-year-old male with a sore throat, tender cervical lymphadenopathy, bilateral erythematous and enlarged tonsils, fever, joint pain, widespread tender purpuric nodules, ulcerative lesions and erythematous pustules. The diagnosis was initially unclear. He had raised neutrophils, erythrocyte sedimentation rate and C-reactive protein. His skin biopsy showed a neutrophilic dermatosis with superficial pustulosis and leukocytoclastic vasculitis. Most likely, the patient suffered from a rare condition called acute febrile neutrophilic dermatosis (AFND). AFND is a very rare disorder of poorly understood aetiology, with only a few hundred reported cases in the literature. The complexity and rarity of this condition, and the difficulty in diagnosing, is an example of the challenge facing paediatricians as the paediatric admission age threshold increases to include older adolescents and young adults up to the age of 25 years, as per the National Health Service (NHS) long-term plan.

A novel heterozygous mutation in the insulin receptor gene presenting with type A severe insulin resistance syndrome.

Background Inherited severe insulin resistance syndromes (SIRS) are rare and can be caused by mutations in the insulin receptor gene (INSR). Case presentation A 12-year-old Jamaican girl with a BMI of 24.4 kg/m2 presented with polyuria and polydipsia. A diagnosis of T1DM was made in view of hyperglycaemia (18 mmol/l), and elevated Hba1C (9.9%), and insulin therapy was initiated. Over the next 2 years, she developed hirsutism and acanthosis nigricans, and had minimal insulin requirements with frequent post-prandial hypoglycaemia. In view of this, and her strong family history suggestive of a dominantly inherited type of diabetes, the diagnosis was revisited. Targeted next-generation sequencing (NGS) of the patient's monogenic diabetes genes was performed. What is new? NGS revealed a novel heterozygous missense INSR variant, NM_000208.3:c.3471T>G, p.(His1157Gln), confirming a diagnosis of Type A SIRS. Conclusions Type A SIRS can be difficult to differentially diagnose due to the variable phenotype. Features of insulin resistance may be absent at initial presentation and may develop later during pubertal progress. Awareness of the clinical features and comprehensive genetic testing are essential to identify the condition.
