Sudden infant death syndrome (SIDS) involves failure of arousal to potentially life threatening events, including hypoxia, during sleep. While neuronal dysfunction and abnormalities in neurotransmitter systems within the medulla oblongata have been implicated, the specific pathways associated with autonomic and cardiorespiratory failure are unknown. The neuropeptide substance P (SP) and its tachykinin neurokinin-1 receptor (NK1R) have been shown to play an integral role in the modulation of homeostatic function in the medulla, including regulation of respiratory rhythm generation, integration of cardiovascular control, and modulation of the baroreceptor reflex and mediation of the chemoreceptor reflex in response to hypoxia...

Brugada syndrome (BrS) is an autosomal dominant inherited channelopathy. It is associated with a typical pattern of ST-segment elevation in the precordial leads V1-V3 and potentially lethal ventricular arrhythmias in otherwise healthy patients. It is frequently seen in young Asian males, in whom it has previously been described as sudden unexplained nocturnal death syndrome. Although it typically presents in young adults, it is also known to present in children and infants, especially in the presence of fever...

Serotonin (5-hydroxytryptamine [5-HT]) neurons in the medulla oblongata project extensively to key autonomic and respiratory nuclei in the brainstem and spinal cord regulating critical homeostatic functions. Multiple abnormalities in markers of 5-HT function in the medulla in sudden infant death syndrome (SIDS) have been reported, informing the hypothesis that at least a subset of SIDS cases is caused by deficits in 5-HT function resulting in impaired homeostatic responses to potentially life-threatening events during sleep...

Pediatric cardiomyopathies are rare diseases with an annual incidence of 1.1 to 1.5 per 100 000. Dilated and hypertrophic cardiomyopathies are the most common; restrictive, noncompaction, and mixed cardiomyopathies occur infrequently; and arrhythmogenic right ventricular cardiomyopathy is rare. Pediatric cardiomyopathies can result from coronary artery abnormalities, tachyarrhythmias, exposure to infection or toxins, or secondary to other underlying disorders. Increasingly, the importance of genetic mutations in the pathogenesis of isolated or syndromic pediatric cardiomyopathies is becoming apparent...

Objective: To estimate annual infant morbidity and mortality attributable to prenatal smoking in Chile during 2008-2012. Methods: Population-attributable fractions (PAFs) for several infant outcomes were calculated based on previous study estimates of prenatal smoking prevalence and odds ratios associated with exposure (prenatal smoking relative to non-prenatal smoking). Prenatal smoking-attributable infant morbidity and mortality cases were calculated by multiplying the average annual number of morbidity and mortality cases registered in Chile during 2008-2012 by the corresponding PAF...

Sudden infant death syndrome (SIDS) remains the leading cause of infant mortality beyond the neonatal period. An increase in body temperature as a result of high environmental temperature, over-wrapping of infants and/or infection are associated with SIDS. Endotoxins such as lipopolysaccharide (LPS) and heat stress may perturb cardiorespiratory function and thermoregulation. Although LPS-mediated body temperature and cytokine responses are well-documented in older animals, the capacity of LPS to induce fever and cytokine response in young rats remains unclear...

Sudden infant death syndrome (SIDS) is the leading cause of post-neonatal infant mortality in developed countries, characterized by the death of infants for no obvious reason and without prior warning. The complex interaction of multiple factors in the pathogenesis of SIDS is illustrated by the 'triple risk hypothesis', which proposed that SIDS results from a convergence of three overlapping risk factors: a critical developmental period, an exogenous stressor, and underlying genetic and/or nongenetic vulnerability in the infant...

A non-linear relationship between maximum ambient temperature and number of sudden infant death syndrome (SIDS) cases had been reported for Montreal, Canada, for the warm season. In particular, high maximum ambient temperatures were found to be extra-hazardous for infants. The study was replicated with data from Vienna, Austria, applying the same statistical approach. Vienna is roughly comparable to Montreal with regard to temperatures in the warm season, size of population, and number of SIDS cases. Although the Viennese study was powerful enough to detect even smaller effects, the Montrealean results could not be confirmed...

Acute myeloid leukaemia (AML) often presents with non-specific symptoms such as fatigue, anaemia or infection. Pulmonary involvement is uncommon in AML during the course of the disease and is usually caused by infection, haemorrhage, leukaemic pulmonary infiltrates and leukostasis. Lung localization of AML is very uncommon and potentially life threatening if not diagnosed and treated rapidly. The authors describe the sudden death of an asymptomatic five-month-infant because of a misdiagnosed lung localization of AML...

Septic shock sometimes starts with unspecific symptoms that hamper the clinical diagnosis and, therefore an appropriate treatment. When the septic shock follows a fulminating course with a fatal outcome, the etiological diagnosis has to be conducted post-mortem. Sudden unexpected deaths in children and young adults are frequently the object of medico-legal autopsies. Some sudden unexpected deaths have an infectious origin, which requires further analyses, including microbiology, to establish the cause of death...

BACKGROUND: Especially in the first 6 months of life, skull deformities manifesting as a uni- or bilateral flattening of the occiput often give rise to questions of differential diagnosis and potential treatment. In this review, the authors summarize the current understanding of risk factors for this condition, and the current state of the relevant diagnostic assessment and options for treatment. METHODS: The recommendations given in this selective review of the literature are based on current studies and on existing guidelines on the prevention of sudden infant death, the recommendations of the German Society for Pediatric Neurology (Deutsche Gesellschaft für Neuropädiatrie), and the American guidelines on the treatment of positional plagiocephaly in infancy...

BACKGROUND AND OBJECTIVES: Prematurity, a strong risk factor for sudden unexpected infant death (SUID), was addressed in recommendations by the American Academy of Pediatrics in 2011 for safe sleep education in NICUs. We documented associations between gestational age (GA) and SUID subsequent to these guidelines. METHODS: Using the 2012-2013 US linked infant birth and death certificate period files, we documented rates per live births of sudden infant death syndrome, ill-defined and unspecified causes, accidental suffocation and strangulation in bed, and overall SUID by GA in postneonatal, out-of-hospital, and autopsied cases; compared survivors and cases; and estimated logistic regression models of associations between GA and SUID...

OBJECTIVES: To quantify and describe variation in cause-of-death certification of sudden unexpected infant deaths (SUIDs) among US medical examiners and coroners. METHODS: From January to November 2014, we conducted a nationally representative survey of US medical examiners and coroners who certify infant deaths. Two-stage unequal probability sampling with replacement was used. Medical examiners and coroners were asked to classify SUIDs based on hypothetical scenarios and to describe the evidence considered and investigative procedures used for cause-of-death determination...

OBJECTIVE: To investigate mothers' knowledge of reducing the risks for sudden infant death syndrome (SIDS) and attitudes towards safer sleep practices. DESIGN AND SETTING: A cross-sectional survey was carried out in deprived areas of Bristol, UK. Recruitment took place in 2014 at local health visitor-led baby clinics. PARTICIPANTS: Of 432 mothers approached, 400 (93%) completed the face-to-face survey. Participants with infants at 'higher' risk of SIDS (using an algorithm based on a previous observational study) were compared with those at 'lower' risk...

In 2015, there was an increase in the number of births in South Dakota compared to the previous year. Further, the state's 2014 birth rate (14.4) exceeded the 12.5 rate observed nationally for this year. Similar to national trends, one-quarter of South Dakota newborns represent minority populations. The infant mortality rate of 7.3 for the state in 2015 was 24 percent higher than the 2014 rate. Analyses of factors that contributed to this increase show that twice as many infants died of sudden unexpected infant death (SUID) in 2015 as has been observed in previous years...

Home cardiorespiratory monitoring has changed significantly since it was first introduced in the 1970s. It has improved from a simple alarm system to a sophisticated piece of equipment capable of monitoring the patient's electrocardiogram, respiratory effort, and oxygen saturations. In addition, the indications for using a monitor have also changed. The home monitor was initially used to reduce the incidence of sudden infant death syndrome (SIDS). Although there were several studies demonstrating the reduction of SIDS rates in communities where apnea programs existed, none was a prospective, double-blinded study or had adequate numbers to be clinically significant...

This review article describes the role of the medicolegal death investigator and medical examiner or coroner (MEC) in the investigations of a sudden unexpected infant death (SUID) beginning with an introduction into the case types that should be investigated and how infant deaths fit into that legal framework. The article also provides an overview of the history of the Centers for Disease Control and Prevention SUID investigation guidelines and process. The article concludes with a description of how the MEC correlates the scene investigation with autopsy findings, as well as the role of the MEC in cause of death determinations...

Although the incidence of sudden unexpected infant death declined by nearly 50% in the 1990s, there has been little improvement in the past 15 years. Significant disparities in infant sleep practices and sleep-associated death exist, particularly by maternal race/ethnicity. This article provides a brief overview of recent observational and intervention studies related to infant sleep practices to describe the context and motivation for the population-based Study of Attitudes and Factors Effecting Infant Care (SAFE)...

Sudden infant death syndrome (SIDS) remains the leading cause of postneonatal mortality in the United States, despite reduction in rates of more than 50% since the initiation of the "Back to Sleep" (now called "Safe to Sleep") campaign in 1994. In recent years, the rate of decline in SIDS deaths has plateaued, even with the ongoing educational efforts that promote safe sleep and other risk reduction measures. The 2016 American Academy of Pediatrics guidelines for reducing the risk of SIDS focus heavily on sleep practices, bedding, and location, but also include factors that often receive less attention (ie, prenatal care, maternal smoking, alcohol and drug use, and childhood vaccinations)...

Sudden unexpected infant death (SUID) is the leading cause for post-neonatal mortality in industrialized nations. Case-control studies have identified risk factors for SUID that have shaped research into studies of causation. Most current hypotheses for the mechanisms for SUID contribute to the "SUID sequence"-hypoxia and/or hypercarbia in sleep to which a vulnerable infant fails to respond adequately and that results in death. Reducing vulnerability in infants and promoting safe sleep for infants is important for prevention and requires knowledge of the prevalence of risk factors within the target population and a culturally sensitive approach...
