Childhood outcomes after low-grade intraventricular haemorrhage: A systematic review and meta-analysis.

AIM: To undertake a systematic review and meta-analysis exploring school-age neurodevelopmental outcomes of children after low-grade intraventricular haemorrhage (IVH). METHOD: The published and grey literature was extensively searched to identify observational comparative studies exploring neurodevelopmental outcomes after IVH grades 1 and 2. Our primary outcome was neurodevelopmental impairment after 5 years of age, which included cognitive, motor, speech and language, behavioural, hearing, or visual impairments. RESULTS: This review included 12 studies and over 2036 infants born preterm with low grade IVH. Studies used 30 different neurodevelopmental tools to determine outcomes. There was conflicting evidence of the composite risk of neurodevelopmental impairment after low-grade IVH. There was evidence of an association between low-grade IVH and lower IQ at school age (-4.23, 95% confidence interval [CI] -7.53, -0.92, I2 = 0%) but impact on school performance was unclear. Studies reported an increased crude risk of cerebral palsy after low-grade IVH (odds ratio [OR] 2.92, 95% CI 1.95, 4.37, I2 = 41%). No increased risk of speech and language impairment or behavioural impairment was found. Few studies addressed hearing and visual impairment. INTERPRETATION: This systematic review presents evidence that low-grade IVH is associated with specific neurodevelopmental impairments at school age, lending support to the theory that low-grade IVH is not a benign condition. WHAT THIS PAPER ADDS: The functional impact of low-grade intraventricular haemorrhage (IVH) at school age is unknown. Low-grade IVH is associated with a lower IQ at school age. The risk of cerebral palsy is increased after low-grade IVH. Low-grade IVH is not associated with speech and language impairment.

School-age outcomes of children after perinatal brain injury: a systematic review and meta-analysis.

BACKGROUND: Over 3000 children suffer a perinatal brain injury in England every year according to national surveillance. The childhood outcomes of infants with perinatal brain injury are however unknown. METHODS: A systematic review and meta-analyses were undertaken of studies published between 2000 and September 2021 exploring school-aged neurodevelopmental outcomes of children after perinatal brain injury compared with those without perinatal brain injury. The primary outcome was neurodevelopmental impairment, which included cognitive, motor, speech and language, behavioural, hearing or visual impairment after 5 years of age. RESULTS: This review included 42 studies. Preterm infants with intraventricular haemorrhage (IVH) grades 3-4 were found to have a threefold greater risk of moderate-to-severe neurodevelopmental impairment at school age OR 3.69 (95% CI 1.7 to 7.98) compared with preterm infants without IVH. Infants with perinatal stroke had an increased incidence of hemiplegia 61% (95% CI 39.2% to 82.9%) and an increased risk of cognitive impairment (difference in full scale IQ -24.2 (95% CI -30.73 to -17.67) . Perinatal stroke was also associated with poorer academic performance; and lower mean receptive -20.88 (95% CI -36.66 to -5.11) and expressive language scores -20.25 (95% CI -34.36 to -6.13) on the Clinical Evaluation of Language Fundamentals (CELF) assessment. Studies reported an increased risk of persisting neurodevelopmental impairment at school age after neonatal meningitis. Cognitive impairment and special educational needs were highlighted after moderate-to-severe hypoxic-ischaemic encephalopathy. However, there were limited comparative studies providing school-aged outcome data across neurodevelopmental domains and few provided adjusted data. Findings were further limited by the heterogeneity of studies. CONCLUSIONS: Longitudinal population studies exploring childhood outcomes after perinatal brain injury are urgently needed to better enable clinicians to prepare affected families, and to facilitate targeted developmental support to help affected children reach their full potential.

Preterm Brain Injury and Neurodevelopmental Outcomes: A Meta-analysis.

CONTEXT: Preterm brain injuries are common; neurodevelopmental outcomes following contemporary neonatal care are continually evolving. OBJECTIVE: To systematically review and meta-analyze neurodevelopmental outcomes among preterm infants after intraventricular hemorrhage (IVH) and white matter injury (WMI). DATA SOURCES: Published and grey literature were searched across 10 databases between 2000 and 2021. STUDY SELECTION: Observational studies reporting 3-year neurodevelopmental outcomes for preterm infants with IVH or WMI compared with preterm infants without injury. DATA EXTRACTION: Study characteristics, population characteristics, and outcome data were extracted. RESULTS: Thirty eight studies were included. There was an increased adjusted risk of moderate-severe neurodevelopmental impairment after IVH grade 1 to 2 (adjusted odds ratio 1.35 [95% confidence interval 1.05-1.75]) and IVH grade 3 to 4 (adjusted odds ratio 4.26 [3.25-5.59]). Children with IVH grade 1 to 2 had higher risks of cerebral palsy (odds ratio [OR] 1.76 [1.39-2.24]), cognitive (OR 1.79 [1.09-2.95]), hearing (OR 1.83 [1.03-3.24]), and visual impairment (OR 1.77 [1.08-2.9]). Children with IVH grade 3 to 4 had markedly higher risks of cerebral palsy (OR 4.98 [4.13-6.00]), motor (OR 2.7 [1.52-4.8]), cognitive (OR 2.3 [1.67-3.15]), hearing (OR 2.44 [1.42-4.2]), and visual impairment (OR 5.42 [2.77-10.58]). Children with WMI had much higher risks of cerebral palsy (OR 14.91 [7.3-30.46]), motor (OR 5.3 [3-9.36]), and cognitive impairment (OR 3.48 [2.18-5.53]). LIMITATIONS: Heterogeneity of outcome data. CONCLUSIONS: Mild IVH, severe IVH, and WMI are associated with adverse neurodevelopmental outcomes. Utilization of core outcome sets and availability of open-access study data would improve our understanding of the nuances of these outcomes.

Urine collection methods and dipstick testing in non-toilet-trained children.

Urinary tract infection is a commonly occurring paediatric infection associated with significant morbidity. Diagnosis is challenging as symptoms are non-specific and definitive diagnosis requires an uncontaminated urine sample to be obtained. Common techniques for sampling in non-toilet-trained children include clean catch, bag, pad, in-out catheterisation and suprapubic aspiration. The pros and cons of each method are examined in detail in this review. They differ significantly in frequency of use, contamination rates and acceptability to parents and clinicians. National guidance of which to use differs significantly internationally. No method is clearly superior. For non-invasive testing, clean catch sampling has a lower likelihood of contamination and can be made more efficient through stimulation of voiding in younger children. In invasive testing, suprapubic aspiration gives a lower likelihood of contamination, a high success rate and a low complication rate, but is considered painful and is not preferred by parents. Urine dipstick testing is validated for ruling in or out UTI provided that leucocyte esterase (LE) and nitrite testing are used in combination.

Presentation of childhood cancers to a paediatric shared care unit.

OBJECTIVE: To describe the pathways by which children with cancer present to a shared care oncology unit. DESIGN: A population-based retrospective cohort study of children diagnosed with cancer between the years 2004 and 2014. SETTING: District General Hospital with a level 2 Paediatric Oncology Shared Care Unit. PATIENTS: 93 children aged 0-15 years . OUTCOME MEASURES: Time to presentation (TTP) was defined as time from initial symptoms to time seen by secondary paediatrics. Time to diagnosis (TTD) was defined as time from initial symptoms to diagnosis at a Principal Treatment Centre. Patient pathways to diagnosis were mapped and routes for different cancers were compared. RESULTS: Only 2/93 cases (2.1%) in 10 years were referred via the 2-week pathway. Most presentations were acute via immediate general practitioner (GP) referral or self-referral to the emergency department 62/93 (67%). Leukaemia presented acutely and via the GP more often than via self-presentation to the emergency department 21/28 (75% vs 25%), while solid tumours were self-referred to the emergency department 21/34 (62% vs 38%) more often than via the GP. TTP and TTD were calculated for 87 patients. Wilms' tumour demonstrated the shortest median TTP of 7 days and TTD of 16 days. Lymphoma had the longest TTD, with TTP 107 days and TTD 120 days. Pathways to diagnosis via other specialties were longer. CONCLUSION: The majority of children diagnosed with cancer present via acute services, with the route varying between tumour types. Only two cases in 10 years were referred via the 2-week pathway, thus challenging its relevance in the paediatric population.
