These cases challenge the under-resourced and non-standardized U.S. medicolegal death investigation system, leaving a devastating impact on affected families (8, 9). Paterson DS, Trachtenberg FL, Thompson EG, Belliveau RA, Beggs AH, Darnall R, et al. At a diagnostic level an absence of procedural guidelines for pediatric death investigation beyond infancy, combined with uneven access to pediatric and neuropathology expertise has resulted in large variation of autopsy standards, with neuropathologic examinations that are frequently insufficient. This is a non-traumatic and sudden death of a child or an adult with epilepsy. It is the lesser-known cousin of Sudden Infant Death Syndrome (SIDS), which the Centers for Disease Control and Prevention (CDC) defines as "the sudden death of an infant less than one year of age that cannot be explained after a thorough investigation is conducted, including a complete autopsy, examination of the death scene, and review of the clinical history." Epilepsia. Then why did she die? Moreover, minor inflammatory infiltrates are common in the lungs and other organs at autopsy, suggesting that post-infectious immunologically mediated processes could also be relevant, although these findings are not specific and occur commonly in other children with well-explained causes of death (1). (1995) 155:23469. When Marissa Wong, 32, received a call from her two-year-old daughters daycare, she thought it would be routine. collaborating to understand and reduce mortality.

Multiple serotonergic brainstem abnormalities in sudden infant death syndrome. Before 2005, few studies considered unexplained post-infancy death other than brief descriptions in occasional medico-legal series primarily concerned with distinguishing natural from unnatural death (7780). (1982) 57:5726. Half of SUDC cases showed HMASD with or without a FS history and the most frequent histologic findings in this group were GCD, FDGB, irregularity of the DG, and ectopic granule cells.

SUDC likely represents a phenotypic endpoint for a heterogeneous group of underlying disorders, the mechanisms of which remain poorly defined. The causes for SUDEP could be the following: These are genetic heart conditions and usually occur in young children and even young adults. SUDC is a major cause of unexpected mortality in toddlers that devastates families. (1994) 65:1947. Retrospective, small SUDC studies with non-standardized methodologies most often demonstrate minor hippocampal abnormalities, as well as focal cortical dysplasia and dysgenesis of the brainstem and cerebellum. Thus, the SUDC Registry and Research Collaborative (SUDCRRC) at NYU Langone Health undertook a 5-year prospective analysis of 20 SUDC cases accrued through a registry where systematic sampling of whole brains was performed with blinded independent reviews conducted by neuropathologists (15). Dr Spencer said: I will work with SUDC to raise this issue and the need for additional support with the NHS and ministers., The Snowdon mums include Tamzin Maynard, whose son Jude died aged seven, and Jane Smith, who lost her daughter in 2019.

What is SUDC?It is the lesser-known cousin of Sudden Infant Death Syndrome (SIDS), which theCenters for Disease Control and Prevention (CDC)defines as the sudden death of an infant less than one year of age that cannot be explained after a thorough investigation is conducted, including a complete autopsy, examination of the death scene, and review of the clinical history., Whatmany parents dont know is that even older children can die suddenly and from no apparent cause.. doi: 10.1111/epi.12489, 24. (1995) 374:5426. A history of minor blunt head injury identified in one quarter of SUDC cases from the initial SDSRP cohort, suggested a potential role for post-concussive mechanisms, although trauma has not been reported as a correlative risk for SUDC in subsequent analyses (1). But meeting Nikki and Camilla was such a relief. The registry provided ex vivo MRI imaging and brain examination by a board-certified neuropathologist. Sharon, 39, of Bushey, Herts, who has two other children with husband James, said: I didnt know anything was wrong until we answered the emergency bleep and I saw my son lying there. A history of FS was present in ~60% of these SUDC cases, substantially more than previously reported cohorts and likely reflecting referral bias from forensic institutions with limited access to neuropathology expertise. 10. It remains unclear whether hippocampal structural changes in SUDC can result from disturbed neurotransmission due to an intrinsic brainstem serotonergic defect arising during early development. Acta Neuropathol. doi: 10.1111/epi.13066, 13. This short video explains the tragedy of Sudden Unexplained Death in Childhood. An audit of the quality of autopsy reporting. (2005) 8:30719. The challenge is that studies typically focus on one or two anatomical structures or functional assays, and the brain has hundreds of networked structures and scores of neurotransmitters, neuromodulators and receptors. Early exploratory analyses of the San Diego SUDC Research Project, (SDSRP), a multicenter initiative created to characterize the main pathologic features and risk profile of SUDC, were key to elucidating the initial relationships between external and microscopic abnormalities of the hippocampus, sudden death during apparent sleep, and FS history (1, 3, 13).

General autopsy findings such as tongue biting and urinary incontinence are occasionally seen in older children and adults; however, these only occur in a minority of cases and lack specificity (2, 3335). Further, the low incidence of SUDC creates additional challenges for healthcare providers who often rely on an interdisciplinary approach to recently bereaved families, and interface with the medico-legal system (8, 11). Bundock E, Corey T. Unexplained Pediatric Deaths. (2017) 88:7015. doi: 10.1136/adc.57.8.572, 79.

Reportedly, SUDC affectsabout 1.4 deaths per 100,000 children globally. 74. Finally, although essential for public health surveillance, the medical death investigation system is under-resourced, short-staffed, and chronically under-funded, problems which have deepened during the opioid epidemic, and COVID-19 novel coronavirus disease pandemic. D'Gama AM, Walsh AC. McGarvey CM, O'Regan M, Cryan J, Treacy A, Hamilton K, Devaney D, et al. Neuropathologic research in SUDC has focused primarily on the hippocampus, with speculative mechanisms of a limbic-brainstem network disorder contributing to epileptogenesis and brainstem dysfunction in susceptible children (48, 56). | Image courtesy: Pixabay. In contrast, SUDC has received relatively little attention, partly because it is such a rare condition The Sudden Death in the Young registry, under the auspices of the Centers for Disease Control and Prevention and the National Institutes for Health is responsible for tracking unexplained infant as well as childhood deaths, although just 13 states or jurisdictions actively participate in this program (75, 76). Some experimental data suggest seizure induced neurogenesis and altered neuronal migration as playing a causal role in GCL alterations (4951). Keeling JW, Knowles AS. Clare, 41, who has three other children with husband Lee in Yearsley, North Yorks, said: I got him to hospital, but nothing could be done. doi: 10.1016/j.pediatrneurol.2012.02.007, 18. By definition, autopsy examination and ancillary studies are negative or reveal only minor pathologic changes insufficient to explain death.

The age of epilepsy onset influences SUDEP risk, which increases with earlier onset epilepsy, implying that developmental mechanisms might influence vulnerability (62, 64). Relative frequency of hippocampal findings and associated changes in SUDC in published series. Deaths are usually unwitnessed, occur during apparent sleep, and most children are discovered in a prone position, often face down (11). Despite reductions in sudden unexpected infant death (SUID) and other causes of mortality in childhood, the rate of SUDC has increased during the past two decades (35). (2013) 12:96677. But we all did it for our children.. doi: 10.1016/S2352-4642(17)30003-2, 12. Thom M, Boldrini M, Bundock E, Sheppard MN, Devinsky O. Investigation, Certification, Family Needs.

The most frequent DG alterations included alternating thickness, irregular configuration, focal GCL loss, and ectopic neuronal clusters. 11:582051. doi: 10.3389/fneur.2020.582051. It is the 5th leading category of death in children aged 14 years, and resulted in 243 deaths in 2017 (7). First defined in 2005, SUDC cases are more often male, with death occurring during a sleep period, being found prone, peak winter incidence, associated with febrile seizure history in ~28% of cases and mild pathologic changes insufficient to explain the death (1, 2). The eight other mums tell their stories here today. If you continue to use this site we will assume that you are happy with it. Presently, experts are trying to understand more about SUDC. As morphometric analysis was not conducted the possibility of heightened sensitivity and observer bias to specific lesions, particularly in more subtle cases, cannot not be entirely excluded. 78. Some children with SUDC had a history of febrile seizures, or a family history of febrile seizures., Dr. Henry Krous, former director of the San Diego SUDC research project (2001 to 2012) alsoexplains, At the present time, there is no way to prevent SUDC as its cause(s) is not known.

Almost 60 percent of toddlers between the ages of one and four who die, die of SUDC. Mum Clare Smith says more research into SUDC is desperately needed to help grieving parents. On the basis of the probable causes of sudden unexplained death of a child, NORD suggests that one must keep an eye out for signs of seizures. Molecular testing has yielded high rates of pathogenic cardiac variants in up to 25% of cases of published sudden death cohorts, and ~12% of explained sudden pediatric deaths which possibly explain cause and mechanism of death in some cases, underscoring the necessity of comprehensive ancillary testing to identify causes (15, 20, 21). The Mortality in Epilepsy Monitoring Units Study, (MORTEMUS), identified 11 SUDEP patients who died after terminal generalized tonic-clonic seizures during epilepsy monitoring (68). A high prevalence of FS history across SUDC cohorts generally comports with a spectrum of neuropathologic hippocampal observations of unclear biologic significance (Table 2). doi: 10.1089/brain.2015.0378, 39. Data Are From the Multiple Cause of Death Files, 1999-2017, as Compiled From Data Provided by the 57 Vital Statistics Jurisdictions Through the Vital Statistics Cooperative Program, Atlanta, GA (2018). When it happens in children under 1 year of age, it's called sudden infant death syndrome (SIDS). Imaging and volumetric assessments of SUDEP brains have demonstrated volume changes affecting brain regions responsible for modulating cardiorespiratory control, including atrophy in areas that protect against cardiorespiratory collapse, and increased volume in areas that predispose to apnea and/or hypotension (69, 70).
