Used infant mattresses and sudden infant death syndrome in Scotland: case-control study

<P>OBJECTIVE: To examine the proposition that a used infant mattress is associated with an increased risk of sudden infant death syndrome. DESIGN: Case-control study. SETTING: Scotland (population 5.1 million, with about 53 000 births a year).</P> <P>PARTICIPANTS: 131 infants who died of sudden infant death syndrome between 1 January 1996 and 31 May 2000 and 278 age, season, and obstetric unit matched control infants.</P> <P>MAIN OUTCOME MEASURES: Routine use of an infant mattress previously used by another child and place of last sleep.</P> <P>RESULTS: Routine use of an infant mattress previously used by another child was significantly associated with an increased risk of sudden infant death syndrome (multivariate odds ratio 3.07, 95% confidence interval 1.51 to 6.22). Use of a used infant mattress for last sleep was also associated with increased risk (6.10, 2.31 to 16.12). The association was significantly stronger if the mattress was from another home (4.78, 2.08 to 11.0) than if it was from the same home (1.64, 0.64 to 4.2).</P> <P>CONCLUSION: A valid significant association exists between use of a used infant mattress and an increased risk of sudden infant death syndrome, particularly if the mattress is from another home. Insufficient evidence is available to judge whether this relation is cause and effect.</P&gt

Sudden infant death syndrome (SIDS) - How to reduce the risk?

Sudden infant death syndrome (SIDS) is a complex, multifactorial phenomenon with an etiology that has not been fully clarified to this day. Despite a noticeable decrease in the number of SIDS cases worldwide, sudden infant death syndrome remains one of the most common causes of death among children in infancy. Sudden infant death syndrome is still the subject of scientific research aimed to clearly determine and identify potential pathogenetic factors responsible for the occurrence of SIDS. Many years of efforts to clarify the etiology of the discussed issue have made it possible to characterize important factors that increase the risk of sudden infant death syndrome. In addition, research has made it possible to develop important approaches that make a significant contribution to reduce the risk of SIDS in an infant. Complete knowledge of the specific conditions that have a protective effect against SIDS will significantly reduce the risk of sudden infant death syndrome, so a very important aspect is not only their precise analysis, but also their propagation among the public

Triadin Knockout Syndrome Is Absent in a Multi-Center Molecular Autopsy Cohort of Sudden Infant Death Syndrome and Sudden Unexplained Death in the Young and Is Extremely Rare in the General Population

Background: Triadin knockout syndrome (TKOS) is a potentially lethal arrhythmia disorder caused by recessively inherited null variants in TRDN-encoded cardiac triadin. Despite its malignant phenotype, the prevalence of TKOS in sudden infant death syndrome and sudden unexplained death in the young is unknown. Methods: Exome sequencing was performed on 599 sudden infant death syndrome and 258 sudden unexplained death in the young cases. Allele frequencies of all TRDN null variants identified in the cardiac-specific isoform of TRDN in the Genome Aggregation Database were used to determine the estimated prevalence and ethnic distribution of TKOS. Results: No triadin null individuals were identified in 599 sudden infant death syndrome and 258 sudden unexplained death in the young exomes. Using the Genome Aggregation Database, we estimate the overall prevalence of TKOS to be ≈1:22.7 million individuals. However, TKOS prevalence is 5.5-fold higher in those of African descent (≈1:4.1 million). Conclusions: TKOS is an exceedingly rare clinical entity that does not contribute meaningfully to either sudden infant death syndrome or sudden unexplained death in the young. However, despite its rarity and absence in large sudden death cohorts, TKOS remains a malignant and potentially lethal disorder which requires further research to better care for these patients

Case-control study of sudden infant death syndrome in Lithuania, 1997–2000

BACKGROUND: To identify risk factors for sudden infant death syndrome relevant in Lithuania. METHODS: A nationwide case-control study surveying parents of 35 infants who died from sudden infant death syndrome during the period of 1997–2000 and parents of 145 control infants matched with SIDS infants for date of birth and for region of birth was carried out. RESULTS: Deaths incidence was greater in the warm period (60%) vs. cold period (40%). Prone and side sleeping positions both carried no increased risk of sudden infant death syndrome compared with supine because of a rare prone sleeping (4.1% of controls vs. 0% of dead infants) and more prevalent side than supine sleeping (84.8% of controls vs. 94.3% of dead infants) in the controls as well as the cases. Bed sharing for the whole night as a risk factor for sudden infant death syndrome has not been confirmed, either, as bed sharing was common only for the controls (13.8% of controls vs. 0% of dead infants). Routine sleeping environment factors such as heavy wrapping (≥4 togs) of an infant (odds ratio 8.49; 95% confidence interval 2.38 to 30.32), sleeping in a bassinet (4.22; 1.16 to 15.38) and maternal factors such as maternal education ≤12 years (4.48; 1.34 to 14.94), unplanned pregnancy (5.22; 1.49 to 18.18) and ≥2 previous live births (3.90; 1.00 to 15.10) were significantly associated with sudden infant death syndrome on multivariate analysis. CONCLUSION: The results of this first population-based case-control study have shed some light on the epidemiology of the syndrome in Lithuania. Although the mortality of sudden infant death syndrome in Lithuania is not high, it might be lowered moreover by public informing about sudden infant death syndrome and related risk factors. Special attention must be paid to mothers with low education on potentially modifiable risk factors such as routine heavy wrapping of an infant during sleep, routine sleeping in a bassinet and unplanned pregnancy

Understanding Sleep-Related Infant Deaths

Sudden Infant Death Syndrome and the Stress-Buffer Model of Social Support

This study examines the effect of social support on the adverse effects of Sudden Infant Death Syndrome stress. The effect of participation in the Sudden Infant Death Syndrome support group on the facilitation of the grief process is also examined. The data for this study were collected from personal interviews with 31 SIDS parents. The data are analyzed within a stress-buffer model of social support

Sudden Infant Death Syndrome: A Case Report in Pakistan

Sudden infant death syndrome (SIDS) is the sudden death of an infant without any identified cause after a complete autopsy report, death scene investigation and from parent’s history. There is little published literature or statistics present in a developing country like Pakistan. So the aim of this study was to identify those factors that are associated with Sudden infant death syndrome in relation to Pakistani culture. The case report was based on a case of two months old baby previously healthy was found dead on his crib. The autopsy report and investigation of the scene giving non-specified symptoms further, diagnose the case as Sudden infant death syndrome. The study found that in our culture early marriages, inadequate knowledge regarding child-rearing and traditional use of Quilts for children are the major contributing factors in the prevention of Sudden infant death syndrome.

Laryngeal inflammation in the sudden infant death syndrome

Sudden infant death syndrome (SIDS) is marked by 'the sudden death of an infant that is unexpected by history and remains unexplained after a thorough forensic autopsy and a detailed death scene investigation'. The cause is unknown. Excessive subglottic submucosal glandular tissue and excessive sulphated mucus glycoprotein in the larynges of SIDS babies have been previously reported from our institution. We now report on laryngeal immunohistology
