Understanding the immune profile of sudden infant death syndrome – proteomic perspectives

Linda Ferrante, Siri H. Opdal, Roger W. Byard

Acta Paediatrica > 113 > 2 > 249 - 255

Aim The aim of this study was to investigate a panel of immune proteins in cases of sudden infant death syndrome (SIDS). It was hypothesised that, in at least a subset of SIDS, a dysregulated immune response may be a contributing factor leading to death. Methods The subjects included 46 SIDS cases and 41 controls autopsied at the Department of Forensic Sciences, Norway. The causes of death in the...

The San Diego SIDS definition—20 Years on

Roger W. Byard, Luzern Tan

Acta Paediatrica > 112 > 7 > 1389 - 1391

Aim As it is now 20 years since the San Diego definition of sudden infant death syndrome (SIDS) was proposed, it is timely to examine the impact of this consensus statement. Results Concerns at the time were expressed that ‘death scene’ had been replaced by circumstances of death and so it may have been more useful to have a more inclusive statement of ‘death scene, including circumstances of death’...

Investigating genetic variants in microRNA regulators of Neurokinin‐1 receptor in sudden infant death syndrome

Zeeshan Shaukat, Roger W. Byard, Robert Vink, Rashid Hussain, more

Acta Paediatrica > 112 > 2 > 273 - 276

Sudden infant death syndrome (SIDS) occurs more often in male than in female infants, suggesting involvement of the X‐chromosome. Histopathological studies have suggested that altered expression of the Neurokinin‐1 receptor may also play a role in the pathogenesis of SIDS. It was hypothesised that genetic variants in three X‐chromosome‐encoded microRNA (miRNA/miR), known to down‐regulate expression...

Luzern Tan, Roger W. Byard

Acta Paediatrica > 111 > 5 > 1019 - 1022

Aim To evaluate the use of the three standard definitions of sudden infant death syndrome (SIDS) in the contemporary literature. Methods A search was undertaken of the US National Library of Medicine ‘PubMed’ database for all research articles listed under ‘sudden infant death syndrome’ or ‘SIDS’, from 2019 to 2021 accessible through the University of Adelaide library. Results 564 papers had...

Is academic rigor in Sudden Infant Death Syndrome (SIDS) research in decline?

Sebastian Oliver Sterling, Roger W. Byard

Acta Paediatrica > 111 > 5 > 1015 - 1018

Aim To determine how well definitions of SIDS in the literature are being cited and referenced. Methods The “PubMed” database was searched for “sudden infant death syndrome” from 2020 to 2021. Of 421 original papers, 50 were randomly selected and checked to determine whether one of the three internationally accepted definitions of SIDS: Seattle, NICHD and San Diego definitions had been cited/quoted...

Vehicular Locard’s principle and patterned tire markings

Roger W. Byard

Journal of Forensic Sciences > 67 > 2 > 806 - 808

A 32‐year‐old man was found dead beside a road with severe complex traumatic brain injuries due to blunt craniocerebral trauma compatible with being run over by a vehicle. A subsequent review of closed‐circuit television (CCTV) footage showed him to be unaccompanied and to fall over beside the road. At autopsy, distinctive black patterned markings were present on the left side of his face and head,...

Methamphetamine and alcohol detection in vehicle‐driver fatalities in South Australia: A 10‐year survey (2008–2018)

Siobhan O’Donovan, Daniel Lewis, Corinna den Heuvel, Matthew Baldock, more

Journal of Forensic Sciences > 67 > 1 > 257 - 264

Motor vehicle driver fatalities (≥18 years) from the files at Forensic Science South Australia were reviewed from January 2008 to December 2018 for cases in which either positive blood sample for methamphetamine (MA) or an illegal blood alcohol concentration (BAC) >0.05g/100 ml were found. Three hundred driver deaths were found with MA detected in 28 cases (age range 21–62 years; ave. 37.8 years;...

Macroscopic identification of visceral titanium pigment in an intravenous drug user

John D. Gilbert, Ken Neubauer, Roger W. Byard

Journal of Forensic Sciences > 66 > 5 > 2024 - 2028

Autopsy findings in intravenous drug addicts are quite variable and may involve a number of organ systems. Reports of the macroscopic identification at autopsy of components of tablets that have been crushed and injected are, however, exceedingly rare. The case of 34‐year‐old man who died of zolpidem toxicity on a background of pulmonary hypertension attributed to intravenous injections of crushed...

Fatal jellyfish envenoming—Pediatric and geographic vulnerabilities

Marianne Tiemensma, Bart J. Currie, Roger W. Byard

Journal of Forensic Sciences > 66 > 5 > 2006 - 2009

Lethal jellyfish envenoming is a very rare event. Two illustrative cases of fatalities following envenomation from the multi‐tentacled box jellyfish, Chironex fleckeri, are reported that involved a six‐year‐old boy and a three‐year‐old girl, both of whom had been playing in shallow beach waters in remote Northern Territory communities (Australia). A recommended approach to autopsy in suspected cases...

Acute Respiratory Obstruction due to Accidental Inhalation of Perlite: A Novel Mechanism for Upper Airway Occlusion with Cast Formation

Marianne Tiemensma, Robert W. Fitzpatrick, Mark D. Raven, Roger W. Byard

Journal of Forensic Sciences > 65 > 4 > 1354 - 1359

A 56‐year‐old man died following a fall resulting in complete submersion into a deep pit containing insulation material, expanded perlite. The most striking finding at autopsy was of impacted, moist pale yellow perlite that extended from the epiglottis into the main bronchi resulting in complete obstruction of the larger and smaller airways with cast formation. Perlite inhalation differs from inhalation...

Increasing Methamphetamine Detection in Cases of Early Childhood Fatalities

Michaela Kenneally, Roger W. Byard

Journal of Forensic Sciences > 65 > 4 > 1376 - 1378

Age and organ maturity can influence drug toxicity in children; however, most clinical data and literature are based on drug concentrations in adults. Therefore, the interpretation of drugs detected in children is often difficult or not possible. Retrospective reviewing of pathology and toxicology information from postmortem cases may assist in future interpretations or identify drug trends. A search...

The use of post‐mortem lividity to determine sleep position in sudden unexpected deaths in infancy

Rebecca Shipstone, John M.D. Thompson, Jeanine Young, Roger W. Byard

Acta Paediatrica > 109 > 6 > 1162 - 1165

Aim To compare parental reports of position found in sudden unexpected deaths in infancy (SUDI) to autopsy reports of lividity and to more accurately classify infant sleep position. Methods Cases of SUDI in Queensland between 2010 and 2014 were reviewed to determine the position in which infants were reported to have been placed and found. This was compared to the distribution of post‐mortem lividity...

Thoracic Visceral Compression–A Useful Technique for Demonstrating Small Bleeding Points in the Dissected Neck at Autopsy

Roger W. Byard

Journal of Forensic Sciences > 65 > 1 > 274 - 275

A 29‐year‐old man died at the scene of an altercation from a stab wound to the left side of the neck. At autopsy, careful in situ examination of the common carotid artery did not reveal any evidence of hemorrhage or apparent vascular injury. However, applying pressure to the chest wall and underlying thoracic viscera (lungs and heart) resulted in filling of the collapsed vessel with blood causing...

Arid Climate Adipocere—The Importance of Microenvironment

Roger W. Byard, Ellie Simpson, Shari L. Forbes

Journal of Forensic Sciences > 65 > 1 > 327 - 329

Skeletal remains were retrieved from a cave in an arid desert environment. The submitted material consisted of dried grass, soil, and malodorous skeletal remains wrapped in leather. After examination, it was revealed that the smell had not been due to recent decomposition but to adipocere. The cause of death was listed as “undetermined” and a suggested date of death as “unknown.” Although adipocere...

How reliable is parental/carer assessment of infant health status?

Roger W. Byard, Rebecca Shipstone, John M. D. Thompson, Jeanine Young

Forensic Science, Medicine and Pathology > 2019 > 15 > 4 > 629-630

Problems often arise in cases of lethal inflicted injury in infants and children in determining the chronology of events. However, on occasion it may be assumed that a parent’s statement that the child appeared normal at a particular time is correct. It is then inferred that the lethal injury occurred after this time. In a study of infants from Queensland, Australia a significant number of cases occurred...
