    Audit of acute limb ischaemia in a paediatric intensive care unit
    (2016) Mumba, Jesse Musokota; Hodges, Owen; Thomas, Jenny
    Objective:Iatrogenic acute limb ischaemia in paediatric patients is a well-recognised complication of vascular access. This retrospective review of a paediatric intensive care unit identified patients who developed iatrogenic acute limb ischaemia between January 2008 and July 2013. Methods: The medical records of inpatients diagnosed with acute limb ischaemia during the study period were reviewed. Patients with other causes of acute limb ischaemia were excluded. A descriptive analysis of demographics, primary diagnosis, type of vascular access used, affected anatomical region, clinical presentation, type of therapy, type of block, response to intervention used and outcomes was conducted. Results:A total of 28 patients presented with signs of acute limb ischaemia, of whom 28.6% were aged <30 days, 46.4 % were between one and 12 months and 25% were between one and five years old; 78.6% of the affected limbs were lower limbs. Four patients had resolution of ischaemia upon removal of the vascular access devices. 23 patients received various forms of pharmacological sympathectomy, in addition to conservative therapy. One patient had missing data on the type of sympathectomy that was done. The response to the sympathectomies was: 60.9% good, 8.7% moderate, 8.7% poor and in 21.7% no responses. Documented tissue loss related to the ischaemia occurred in six (21.4%) of the 28 patients. Conclusions: Iatrogenic acute limb ischaemia in children are usually managed without surgical intervention. Pharmacological sympathectomies lead to increased blood flow to the affected limb via vasodilatation of collateral vessels, with an added advantage of reducing ischemic pain. The improved blood flow is postulated to avoid and/or minimise the amount of tissue loss. Pharmacological sympathectomies may, thus, have a role to play in th e management of iatrogenic acute limb ischaemia in the paediatric population.

    Liver transient elastography values in healthy South African children
    (2023-07-13) Rose, Penelope C.; Cotton, Mark F.; Otwombe, Kennedy; Innes, Steve; Nel, Etienne D.
    Abstract Background Transient elastography (TE) is a rapid noninvasive ultrasound-based technology that measures liver stiffness as a surrogate for liver fibrosis and controlled attenuation parameter (CAP) as a measure of liver steatosis. However, normal ranges in children are not well defined in all populations. The aim of this study was to determine transient elastography values in healthy South African children. Methods From April 2019 to December 2021, children were recruited from the HIV negative control group of a cohort study. Only children neither overweight nor obese, without evidence of liver disease, no medical condition or medication associated with hepatic steatosis or fibrosis and normal metabolic profile were included in this cross-sectional analysis. Clinical data, anthropometry and blood samples were collected on the same day as transient elastography with controlled attenuation parameter was performed. Results 104 children (median age 12.8 years [IQR 11.4–14.8, range 7.9–17.7 years]; 59 [57%] boys) were included. Liver stiffness was positively correlated with age (Pearson’s r = 0.39, p < 0.001). Median liver stiffness in boys (5.2 kPa [5th to 95th percentiles 3.6 to 6.8 kPa]) was greater than in girls (4.6 kPa [5th to 95th percentiles 3.6 to 6.1 kPa; p = 0.004]), but there was no difference by ethnicity. Median CAP was 179dB/m (5th to 95th percentiles 158 to 233dB/m). There was a positive correlation between CAP and body mass index (BMI) z-score, but no difference by age, sex, ethnicity or pubertal status. Conclusion Liver stiffness values increase with age and are higher in healthy South African boys than girls, whereas CAP values vary with BMI, but not with age or sex.

    Outcomes following admission to paediatric intensive care: A systematic review
    (2020) Procter, Claire; Argent, Andrew; Morrow, Brenda
    Introduction Paediatric Intensive Care has developed rapidly in recent years with a dramatic increase in survival rates. However, there are increasing concerns regarding the impact that admission to a Paediatric Intensive Care Unit (PICU) has on both the child and their family. Following discharge from PICU, children may be living with complex medical problems as well as dealing with the psychosocial impact that their illness has had on them and their family. Objectives To describe the long-term health outcomes of children admitted to a paediatric intensive care unit (PICU). Methods A full literature search was conducted including the databases; MEDLINE via PubMed, Cochrane Central Register of Controlled Trials, (CENTRAL), Scopus, Web of Science, CINAHL, ERIC, Health Source Nursing/Academic, APA PsycInfo. All studies including children under 18 admitted to a PICU were included. Primary outcome was short- and longerterm mortality. Secondary outcomes were neurodevelopment/cognition/school performance; physical function, psychological function/behaviour impact, quality of life outcomes and social/family implications. Studies focused on Neonatal Intensive Care Admission and articles with no English translation were excluded. Results One hundred and five articles were included in the analysis. Mortality in PICU ranged from 1.3% to 50%. Mortality in high income countries reduced over time but the data did not show the same trend for low- and middle-income countries. Higher income countries were found to have lower Standardised Mortality Rates (SMRs) than low- and middle-income countries. Children had an ongoing risk of death for up to 10 years following PICU admission. Children admitted to PICU also have more ongoing morbidity than their healthy counterparts with more cognitive/developmental problems, more functional health issues, poorer quality of life as well as increased psychological problems. Their parents also have an increased risk of Post Traumatic Stress Disorder (PTSD). Discussion Most of the studies identified are from high income countries and only include short-term follow up. More data is needed from low- and middle-income countries and over longer terms. The studies were markedly heterogenous and were all observational. Agreement is needed regarding which outcomes are most important to measure as well as standardised methods of assessing them. Further research is needed to identify the risk factors which cause children to have poorer outcomes as well as to identify predictive and modifiable factors which could be targeted in practice improvement initiatives.

    Paediatric and Adolescent civilian gunshot injuries: a 10 year epidemiological study
    (2025) Verfuss, Frances; Maqungo, Sithombo
    Introduction: In South Africa, the prevalence of violent crime, especially involving firearms, poses a significant public health challenge, particularly when it affects children. Previous studies showed a decrease in paediatric civilian gunshot injuries following the introduction of the 2004 Firearms Control Act. This study examines the epidemiological trends of gunshot injuries in children from January 2011 to December 2020. Methods: A descriptive cross-sectional study was performed on children aged 0-12 years presenting to the Red Cross War Memorial Children's Hospital (RXH) in Cape Town with gunshot injuries from January 2011 to December 2020. The data were drawn from the ChildSafe database and hospital records. We evaluated demographics, injury specifics, and orthopaedic outcomes. Results: The number of gunshot wounds(GSW) in the observational record showed an increasing trend of +2.69 (95%CI 1.05 – 4.33) patients per year with a total of 236 patients affected. There was a male predominance (56.8%), with the largest age group affected being children aged 5-9 years (44%). Orthopaedic injuries were prevalent in 69 patients (29.2%), including fractures and injuries to the peripheral nerves and spinal cord. A total of 71 fractures were recorded, with 54 occurring in the extremities and 17 involving the spine or pelvis. The lower extremities were most affected, necessitating surgical interventions such as external fixators and/or femur nails. Peripheral nerve injuries and spinal cord injuries resulted in significant long-term morbidities. The severity and complexity of all assessed injuries often required multiple surgical procedures and extended hospital stays, with an admission length of ~10 days, with some patients requiring intensive care (17.37% of cases). Morbidity included complications like wound infections and long-term disabilities such as paralysis and traumatic brain injuries. Conclusion: Despite legislative measures aimed at reducing such incidents, this study reveals an upward trend in gunshot injuries among children in Cape Town. Gunshot injuries remain a significant and increasing public health challenge among paediatric populations in Cape Town, with profound implications for morbidity, mortality, and healthcare resource utilization. Addressing this issue requires a comprehensive and multi-sectoral approach that prioritizes prevention, early intervention, and addressing the underlying social determinants of violence.

    Paediatric nonbronchoscopic bronchoalveolar lavage: Overview and recommendations for clinical practice
    (AOSIS, 2006) Morrow, B M; Futter, M J; Argent, A C
    NB-BAL is an effective procedure for the diagnosis of pulmonary disease processes in ventilated infants and children. This procedure is, however, not without risks to both patients and staff. Numerous complications of NB-BAL exist, with hypoxia being the most common. As a result, care should be taken in performing NB-BAL on haemodynamically unstable patients; patients with coagulation defects; and patients with cardiac or brain abnormalities. This paper presents an overview of paediatric nonbronchoscopic bronchoalveolar lavage (NB-BAL) including: the rationale for NB-BAL; the complications associated with the procedure; indications and contraindications. It also recommends an evidence-based clinical guideline for performing the procedure in the paediatric intensive care unit. By following the NB-BAL guidelines presented in this paper, one can ensure that an effective specimen is obtained from the lower respiratory tract, whilst minimising the risk to the patient.

    Reference intervals for the echocardiographic measurements of the right heart in children and adolescents: a systematic review
    (BioMed Central Ltd, 2014) Lemmer (Hunsinger), Carolina; Engel, Mark E; Stanfliet, John; Mayosi, Bongani
    BACKGROUND: Transthoracic echocardiography is the primary imaging modality for the diagnosis of right ventricular (RV) involvement in congenital and acquired heart diseases. There is increasing recognition of the contribution of RV dysfunction in heart diseases affecting children and adolescents, but there is insufficient information on reference intervals for the echocardiographic measurements of the right heart in children and adolescents that represent all the continental populations of the world.OBJECTIVE:The aim of this systematic review was to collate, from published studies, normative data for echocardiographic evaluation of the right heart in children and adolescents, and to identify gaps in knowledge in this field especially with respect to sub-Saharan Africans. METHODS: We performed a systematic literature search to identify studies of reference intervals for right heart measurements as determined by transthoracic echocardiography in healthy children and adolescents of school-going age. Articles were retrieved from electronic databases with a combination of search terms from the earliest date available until May 2013. RESULTS: Reference data were available for a broad range of variables. Fifty one studies out of 3096 publications were included. The sample sizes of the reference populations ranged from 13 to 2036 with ages varying from 5 to 21 years. We identified areas lacking sufficient reference data. These included reference data for determining right atrial size, tricuspid valve area, RV dimensions and areas, the RV % fractional area change, pulmonary artery pressure gradients and the right-sided haemodynamics, including the inferior vena cava dimensions and collapsibility. There were no data for sub-Saharan African children and adolescents. CONCLUSION: Reliable reference data are lacking for important echocardiographic measurements of the RV in children and adolescents, especially for sub-Saharan Africans.

    Valuing EQ-5D-Y: the current state of play
    (2022-07-06) Devlin, N; Pan, T; Kreimeier, S; Verstraete, J; Stolk, E; Rand, K; Herdman, M
    Background For nearly a decade, value sets for the EQ-5D-Y were not available, reflecting challenges in valuing child HRQoL. A methodological research programme led to publication of a valuation protocol in 2020, which was rapidly taken up by local study teams. By the end of 2022, between 11 and 17 EQ-5D-Y value sets will be available, more than for any other child HRQoL measure. It is timely to review the experience of those using the protocol to identify early learnings and remaining issues where more research is needed. Methods In June 2021, the EuroQol Group organised a three-day workshop, bringing together all those involved in EQ-5D-Y value set studies and related methodological research concerning EQ-5D-Y and valuation. Workshop discussions were captured by note taking and recording all sessions and online chat. A narrative summary of all sessions was produced and synthesised to identify points of agreement and aspects of methods where uncertainty remains. Results There was broad agreement that DCE is working well as the principal valuation method. However, the most appropriate means of anchoring the latent scale values produced by DCE remains unclear. Some studies have deviated from the protocol by extending the number of states included in TTO tasks, to better support modelling of DCE and TTO. There is ongoing discussion about the relative merits of alternative variants of TTO and other methods for anchoring. Very few studies have consulted with local end-users to gauge the acceptability of methods used to value EQ-5D-Y. Conclusions Priority areas for research include testing alternative methods for anchoring DCE data; exploring the preferences of adolescents; and scale differences in values for EQ-5D-Y and adult EQ-5D states, and implications of such differences for the use of EQ-5D-Y values in HTA. Given the normative elements of the protocol, engaging with HTA bodies and other local users should be the first step for all future value set studies. Value sets undertaken to date are for the three-level EQ-5D-Y. However, the issues discussed in this paper are equally relevant to valuation of the five-level version of EQ-5D-Y; indeed, similar challenges are encountered valuing any measure of child HRQoL.
