Pacifier Use and Sids: Evidence for a Consistently Reduced Risk

Sleep apnea pathophysiology

OBJECTIVE

The purpose of this study is to examine the pathophysiology underlying sleep apnea (SA).

BACKGROUND

We consider several critical features of SA including the roles played by the ascending reticular activating system (ARAS) that controls vegetative functions and electroencephalographic findings associated with both SA and normal sleep. We evaluate this knowledge together with our current understanding of the anatomy, histology, and physiology of the mesencephalic trigeminal nucleus (MTN) and mechanisms that contribute directly to normal and disordered sleep. MTN neurons express γ-aminobutyric acid (GABA) receptors which activate them (make chlorine come out of the cells) and that can be activated by GABA released from the hypothalamic preoptic area.

METHOD

We reviewed the published literature focused on sleep apnea (SA) reported in Google Scholar, Scopus, and PubMed databases.

RESULTS

The MTN neurons respond to the hypothalamic GABA release by releasing glutamate that activates neurons in the ARAS. Based on these findings, we conclude that a dysfunctional MTN may be incapable of activating neurons in the ARAS, notably those in the parabrachial nucleus, and that this will ultimately lead to SA. Despite its name, obstructive sleep apnea (OSA) is not caused by an airway obstruction that prevents breathing.

CONCLUSIONS

While obstruction may contribute to the overall pathology, the primary factor involved in this scenario is the lack of neurotransmitters.

Evidence Base for 2022 Updated Recommendations for a Safe Infant Sleeping Environment to Reduce the Risk of Sleep-Related Infant Deaths

Every year in the United States, approximately 3500 infants die of sleep-related infant deaths, including sudden infant death syndrome (SIDS) (International Statistical Classification of Diseases and Related Health Problems 10th Revision [ICD-10] R95), ill-defined deaths (ICD-10 R99), and accidental suffocation and strangulation in bed (ICD-10 W75). After a substantial decline in sleep-related deaths in the 1990s, the overall death rate attributable to sleep-related infant deaths have remained stagnant since 2000, and disparities persist. The triple risk model proposes that SIDS occurs when an infant with intrinsic vulnerability (often manifested by impaired arousal, cardiorespiratory, and/or autonomic responses) undergoes an exogenous trigger event (eg, exposure to an unsafe sleeping environment) during a critical developmental period. The American Academy of Pediatrics recommends a safe sleep environment to reduce the risk of all sleep-related deaths. This includes supine positioning; use of a firm, noninclined sleep surface; room sharing without bed sharing; and avoidance of soft bedding and overheating. Additional recommendations for SIDS risk reduction include human milk feeding; avoidance of exposure to nicotine, alcohol, marijuana, opioids, and illicit drugs; routine immunization; and use of a pacifier. New recommendations are presented regarding noninclined sleep surfaces, short-term emergency sleep locations, use of cardboard boxes as a sleep location, bed sharing, substance use, home cardiorespiratory monitors, and tummy time. In addition, additional information to assist parents, physicians, and nonphysician clinicians in assessing the risk of specific bed-sharing situations is included. The recommendations and strength of evidence for each recommendation are published in the accompanying policy statement, which is included in this issue.

Toward a speech-motor account of the effect of Age of Pacifier Withdrawal

Recently published works suggest that prolonged pacifier use affects abstract word processing later in life. Using the pacifier beyond age 3 years affects the conceptual relations used to define the meaning of words at age 6 years. Similarly, when semantically categorizing a set of abstract, concrete and emotional words, children aged 8 years who used the pacifier for a longer period of time were slower to process abstract stimuli, but not concrete and emotional ones. The children of these studies had typical development and no diagnosis of cognitive or linguistic disorders. These results, although correlational, suggest a possible relationship between extended use of a pacifier and the development of language skills, particularly for abstract words. The first goal of this theoretical work is to outline current evidence suggesting an association between prolonged pacifier use and the processing of abstract words. The second goal is to propose an account of the effect of Age of Pacifier Withdrawal (APW) within the DIVA neurocomputational model of speech development and production (Guenther & Vladusich, 2013). Using the pacifier during social interaction for a longer period might impede the processing of proprioceptive information and speech-motor programs (i.e., by limiting the co-articulation of speech, it could inhibit the building and consolidation of speech-motor articulatory gestures) as well as auditory input (because the child receives inaccurate input about his/her own speech). Thus, it seems useful to explore the auditory speech representation of children who use a pacifier beyond 3 years of age. We suggest that after the first year of life pacifier use should be impeded during social interaction and limited to use at bed time.

Sudden Infant Death Syndrome: Beyond Risk Factors

Sudden infant death syndrome (SIDS) is defined as "the sudden death of an infant under 1 year of age which remains unexplained after thorough investigation including a complete autopsy, death scene investigation, and detailed clinical and pathological review". A significant decrease of SIDS deaths occurred in the last decades in most countries after the beginning of national campaigns, mainly as a consequence of the implementation of risk reduction action mostly concentrating on the improvement of sleep conditions. Nevertheless, infant mortality from SIDS still remains unacceptably high. There is an urgent need to get insight into previously unexplored aspects of the brain system with a special focus on high-risk groups. SIDS pathogenesis is associated with a multifactorial condition that comprehends genetic, environmental and sociocultural factors. Effective prevention of SIDS requires multiple interventions from different fields. Developing brain susceptibility, intrinsic vulnerability and early identification of infants with high risk of SIDS represents a challenge. Progress in SIDS research appears to be fundamental to the ultimate aim of eradicating SIDS deaths. A complex model that combines different risk factor data from biomarkers and omic analysis may represent a tool to identify a SIDS risk profile in newborn settings. If high risk is detected, the infant may be referred for further investigations and follow ups. This review aims to illustrate the most recent discoveries from different fields, analyzing the neuroanatomical, genetic, metabolic, proteomic, environmental and sociocultural aspects related to SIDS.

Maternal psychosocial predictors of pacifier use in a mother-infant interaction task: An observational study from the MPEWS pregnancy cohort

The prevalence of pacifier use is high but when it occurs outside of the recommended sleep context, it becomes more controversial. Using 211 mother-infant dyads recorded as part of the Mercy Pregnancy and Emotional Wellbeing Study, we examined the maternal psychosocial predictors of pacifier use within an interaction task (i.e., ten minutes face-to-face followed by 30-minutes unstructured play). Predictors included maternal emotional availability measured with the Emotional Availability Scales; depression measured by the Structured Clinical Interview for the DSM-IV-TR Clinician Version; and maternal history of childhood trauma measured by the Childhood Trauma Questionnaire. An unadjusted odds ratio demonstrated that women classified as non-emotionally available to their infants were three-and-a-half-times more likely to use a pacifier. Multivariate logistic regression including all maternal psychosocial predictors demonstrated that even when adjusting for cessation of breastfeeding, maternal emotional availability remained the only significant predictor of pacifier use. This is the first time that predictors of pacifier use have been examined with a sample of clinically depressed women, as well as women with childhood trauma history. The results provide preliminary evidence that women who are not emotionally available might be more likely to rely on a pacifier during mother-infant interaction.

Pacifier Use and Breastfeeding: A Qualitative Study of Postpartum Mothers

Objective: Due to the inconclusive evidence supporting the traditional recommendation to avoid early pacifier use among breastfeeding newborns, this study aims to understand what information mothers are receiving from hospital based care providers and their perspectives about pacifier use in the newborn period. Methods: Interviews with mothers of healthy, term newborns during the postpartum hospitalization were conducted in this qualitative study. Results: Qualitative data analysis yielded several major themes that included the following: (1) pacifiers are beneficial for the maternal/infant experience, (2) concerns that pacifiers may interfere with breastfeeding, and (3) concerns about long-term use (including reliance and effect on teeth). Conclusion: Given the maternal perception of benefit and the paucity of high-quality evidence showing harm, further research on the effects of early pacifier use is needed.

Impact of a Baby-Friendly-Aligned Pacifier Policy on Pacifier Use at 1 Month of Age

OBJECTIVE

Pacifier use decreases the risk of sudden infant death syndrome, but its impact on breastfeeding remains controversial. We evaluated the impact of a pacifier policy aligned with the World Health Organization and United Nations Children's Fund Baby-Friendly Hospital Initiative on subsequent pacifier use and breastfeeding at 1 month of age.

METHODS

We conducted a prospective 2-stage (pre- and post-implementation) cohort study of newborns at a birth hospital before and after implementation of a Baby-Friendly-aligned pacifier policy. Consecutive mothers of newborns admitted to the nursery participated in a telephone survey when the infants were 1 month of age.

RESULTS

In total, 342 mothers participated (190 before and 152 after implementation of the policy). Pacifier adoption was delayed in the post-implementation group, but pacifier use by 1 month of age was comparable (78.9% pre-implementation vs 77.6% post-implementation; P = .793). In the pre-implementation group, female and male infants used pacifiers at comparable rates; however, in the post-implementation group, females were significantly less likely to use a pacifier compared to males after controlling for insurance, race, parity, and delivery mode (adjusted odds ratio, 0.35; 95% confidence interval, 0.15-0.83; P = .02). In the post-implementation group, exclusive breastfeeding rates at discharge increased significantly (from 40% to 51.3%; P = .04), but rates were not different at 1 month (23.7% pre-implementation vs 24.3% post-implementation; P = .89).

CONCLUSION

A Baby-Friendly-aligned pacifier policy delayed pacifier adoption but did not impact overall pacifier use or breastfeeding rates at 1 month of age. The finding of lower pacifier use rates among female infants post-intervention requires verification in other populations before evaluating public heath relevance.

Preventing sudden infant death syndrome and other sleep-related infant deaths

Sudden infant death syndrome, a type of sleep-related sudden unexpected infant death (SUID) is the leading cause of postneonatal mortality in the United States and the third leading cause of infant death overall. Despite the evidence-based risk-reduction strategies and the highly publicized campaigns for a safe sleep environment, some infants continue to sleep in unsafe sleep conditions. Clinicians need to know the current best practices to reduce the incidence of sleep-related SUID and be knowledgeable to counsel caregivers who may resist adhering to these recommendations. This article describes the different types of SUID, associated risk factors, and highlights recommendations to help parents and caregivers ensure safe sleep environments for infants.

Trends in the Incidence of Sudden Unexpected Infant Death in the Newborn: 1995-2014

OBJECTIVE

To evaluate the epidemiology of sudden unexpected infant death (SUID) over a 20-year period in the US, to assess the potential frequency of sudden unexpected postnatal collapse in the early days of life, and to determine if SUID rates in the neonatal period (0-27 days) have changed in parallel with rates in the postneonatal periods, including the percentages attributed to codes that include accidental suffocation.

STUDY DESIGN

Data from the US Centers for Disease Control and Prevention Linked Birth/Infant Death Records for 1995-2014 were analyzed for the first hour, day, week, and month of life. A comparison of neonatal and postneonatal data related to SUID, including accidental suffocation, was carried out.

RESULTS

Death records for 1995-2014 indicate that, although SUID rates in the postneonatal period have declined subsequent to the 1992 American Academy of Pediatrics sleep position policy change, newborn SUIDs have failed to decrease, and the percentage of SUIDs attributed to unsafe sleep conditions has increased significantly in both periods; 29.2% of the neonatal cases occurred within the first 6 days of life.

CONCLUSIONS

The frequency of SUIDs during the neonatal period warrants ongoing attention to all circumstances contributing to this category of deaths. The development of a standardized definition of sudden unexpected postnatal collapse and a national registry of these events is recommended. Ongoing research on the effects of early neonatal practices on postneonatal SUID should also be encouraged.

Risky Behaviors of Mothers with Infants on Sudden Infant Death Syndrome in Turkey

PURPOSE

Sudden infant death syndrome is the most common cause of death during the post-neonatal period. Factors such as sleeping position, bed sharing, pillow use, smoking during pregnancy and the breastfeeding period constitute risk factors for sudden infant death syndrome. This study aims to identify the risky behaviors of mothers with infants that may put their children at risk for sudden infant death syndrome.

DESIGN AND METHODS

This is a cross-sectional, descriptive study. Data were collected using a questionnaire that was developed by the researchers. The questionnaire was filled out by 456 mothers who applied to the family health center between October 2014 and January 2015.

RESULTS

The greatest risk factor is the infant's sleeping position. A total of 77.9% of the mothers put their babies in bed in a non-supine position; 65.8% used a pillow when they put their babies in bed, 52.9% used a soft mattress, and 28.5% shared their beds with their babies. Prone sleeping was more likely to occur when smoke was present in the home or a pillow was used.

CONCLUSION

Nurses should notify families of the risky behaviors that can cause sudden infant death syndrome and plan appropriate nursing care.

When is the use of pacifiers justifiable in the baby-friendly hospital initiative context? A clinician's guide

BACKGROUND

The use of pacifiers is an ancient practice, but often becomes a point of debate when parents and professionals aim to protect and promote breastfeeding as most appropriately for nurturing infants. We discuss the current literature available on pacifier use to enable critical decision-making regarding justifiable use of pacifiers, especially in the Baby-Friendly Hospital Initiative context, and we provide practical guidelines for clinicians.

DISCUSSION

Suck-swallow-breathe coordination is an important skill that every newborn must acquire for feeding success. In most cases the development and maintenance of the sucking reflex is not a problem, but sometimes the skill may be compromised due to factors such as mother-infant separation or medical conditions. In such situations the use of pacifiers can be considered therapeutic and even provide medical benefits to infants, including reducing the risk of sudden infant death syndrome. The argument opposing pacifier use, however, is based on potential risks such as nipple confusion and early cessation of breastfeeding. The Ten Steps to Successful Breastfeeding as embedded in the Baby-Friendly Hospital Initiative initially prohibited the use of pacifiers in a breastfeeding friendly environment to prevent potential associated risks. This article provides a summary of the evidence on the benefits of non-nutritive sucking, risks associated with pacifier use, an identification of the implications regarded as 'justifiable' in the clinical use of pacifiers and a comprehensive discussion to support the recommendations for safe pacifier use in healthy, full-term, and ill and preterm infants. The use of pacifiers is justifiable in certain situations and will support breastfeeding rather than interfere with it. Justifiable conditions have been identified as: low-birth weight and premature infants; infants at risk for hypoglyceamia; infants in need of oral stimulation to develop, maintain and mature the sucking reflex in preterm infants; and the achievement of neurobehavioural organisation. Medical benefits associated with the use of pacifiers include providing comfort, contributing towards neurobehavioural organisation, and reducing the risk of sudden infant death syndrome. Guidelines are presented for assessing and guiding safe pacifier use, for specific design to ensure safety, and for cessation of use to ensure normal childhood development.

Pacifier Use, Finger Sucking, and Infant Sleep

Few studies to date have investigated the relationship between pacifier use or finger sucking and infant sleep. One hundred and four mothers of infants (ages 0-11 months) completed the Brief Infant Sleep Questionnaire (BISQ). Infants who engaged in finger sucking had fewer night wakings and longer stretches of nighttime sleep, although less daytime sleep. There were no significant differences in sleep patterns between pacifier users and infants who did not engage in nonnutritive sucking. Furthermore, no significant differences were found across groups for sleep ecology, including parental involvement at bedtime and following night wakings. Finally, infants were consistently able to retrieve their pacifiers independently by 7 months of age, although this did not appear to be associated with sleep outcomes. Results suggest that when parents are deciding whether to give their infant a pacifier, sleep may not be a critical factor. In contrast, parents of finger and thumb suckers should be reassured that this nonnutritive sucking is beneficial to sleep, at least in the first year of life.

SIDS and Other Sleep-Related Infant Deaths: Evidence Base for 2016 Updated Recommendations for a Safe Infant Sleeping Environment

Approximately 3500 infants die annually in the United States from sleep-related infant deaths, including sudden infant death syndrome (SIDS), ill-defined deaths, and accidental suffocation and strangulation in bed. After an initial decrease in the 1990s, the overall sleep-related infant death rate has not declined in more recent years. Many of the modifiable and nonmodifiable risk factors for SIDS and other sleep-related infant deaths are strikingly similar. The American Academy of Pediatrics recommends a safe sleep environment that can reduce the risk of all sleep-related infant deaths. Recommendations for a safe sleep environment include supine positioning, use of a firm sleep surface, room-sharing without bed-sharing, and avoidance of soft bedding and overheating. Additional recommendations for SIDS risk reduction include avoidance of exposure to smoke, alcohol, and illicit drugs; breastfeeding; routine immunization; and use of a pacifier. New evidence and rationale for recommendations are presented for skin-to-skin care for newborn infants, bedside and in-bed sleepers, sleeping on couches/armchairs and in sitting devices, and use of soft bedding after 4 months of age. In addition, expanded recommendations for infant sleep location are included. The recommendations and strength of evidence for each recommendation are published in the accompanying policy statement, "SIDS and Other Sleep-Related Infant Deaths: Updated 2016 Recommendations for a Safe Infant Sleeping Environment," which is included in this issue.

Effects of pacifier and taste on swallowing, esophageal motility, transit, and respiratory rhythm in human neonates

BACKGROUND

Pacifier use is widely prevalent globally despite hygienic concerns and uncertain mechanistic effects on swallowing or airway safety.

AIMS

The effects of pacifier and taste interventions on pharyngo-esophageal motility, bolus transit, and respiratory rhythms were investigated by determining the upper esophageal sphincter (UES), esophageal body, esophagogastric junction (EGJ) motor patterns and deglutition apnea, respiratory rhythm disturbances, and esophageal bolus clearance.

METHODS

Fifteen infants (six males; median gestation 31 weeks and birth weight 1.4 kg) underwent high-resolution impedance manometry at 43 (41-44) weeks postmenstrual age. Manometric, respiratory, and impedance characteristics of spontaneous swallows, pacifier-associated dry swallowing and taste (pacifier dipped in 3% sucrose)-associated swallowing were analyzed. Linear mixed and generalized estimating equation models were used. Data are presented as mean ± SEM, %, or median (IQR).

KEY RESULTS

Pharyngo-esophageal motility, respiratory, and impedance characteristics of 209 swallows were analyzed (85 spontaneous swallows, 63 pacifier- swallows, 61 taste- swallows). Basal UES and EGJ pressures decreased upon pacifier (p < 0.05) and taste interventions (p < 0.05); however, esophageal motility, respiratory rhythm, and impedance transit characteristics were similar with both interventions.

CONCLUSIONS & INFERENCES

Oral stimulus with pacifier or taste interventions decreases UES and EGJ basal pressure, but has no effects on pharyngo-esophageal motility, airway interactions, or esophageal bolus transit. A decrease in central parasympathetic-cholinergic excitatory drive is likely responsible for the basal effects.

Reasons for Pacifier Use and Non-Use in African-Americans: Does Knowledge of Reduced SIDS Risk Change Parents' Minds?

To investigate African-American parental reasons for pacifier use or non-use, and whether knowledge of the association with decreased SIDS risk changes decisions about pacifier use. We conducted focus groups and individual interviews with mothers. Grounded theory methodology was used. 83 mothers participated; 72.3 % of infants used pacifiers. Reasons for pacifier use included comfort/soothing, safety/SIDS, and preference over digit-sucking. Reasons for pacifier non-use included infant refusal, fear of attachment, nipple confusion, and germs. Many parents were unaware that pacifier use reduces SIDS risk; however, most parents of non-users did not think that this knowledge would have changed their decision. Reasons included skepticism about the pacifier-SIDS link. Many reasons underlie African-American parental decisions about pacifier use. Providers should provide information about the benefits of pacifiers. Establishing for parents any plausible link between the protective mechanism of pacifiers and SIDS pathophysiology may be important in promoting pacifier use.

Parent-child bed-sharing: The good, the bad, and the burden of evidence

The practice of parent and child sharing a sleeping surface, or 'bed-sharing', is one of the most controversial topics in parenting research. The lay literature has popularized and polarized this debate, offering on one hand claims of dangers, and on the other, of benefits - both physical and psychological - associated with bed-sharing. To address the scientific evidence behind such claims, we systematically reviewed 659 published papers (peer-reviewed, editorial pieces, and commentaries) on the topic of parent-child bed-sharing. Our review offers a narrative walkthrough of the many subdomains of bed-sharing research, including its many correlates (e.g., socioeconomic and cultural factors) and purported risks or outcomes (e.g., sudden infant death syndrome, sleep problems). We found general design limitations and a lack of convincing evidence in the literature, which preclude making strong generalizations. A heat-map based on 98 eligible studies aids the reader to visualize world-wide prevalence in bed-sharing and highlights the need for further research in societies where bed-sharing is the norm. We urge for multiple subfields - anthropology, psychology/psychiatry, and pediatrics - to come together with the aim of understanding infant sleep and how nightly proximity to the parents influences children's social, emotional, and physical development.

Sudden infant death syndrome caused by cardiac arrhythmias: only a matter of genes encoding ion channels?

Sudden infant death syndrome is the unexpected demise of a child younger than 1 year of age which remains unexplained after a complete autopsy investigation. Usually, it occurs during sleep, in males, and during the first 12 weeks of life. The pathophysiological mechanism underlying the death is unknown, and the lethal episode is considered multifactorial. However, in cases without a conclusive post-mortem diagnosis, suspicious of cardiac arrhythmias may also be considered as a cause of death, especially in families suffering from any cardiac disease associated with sudden cardiac death. Here, we review current understanding of sudden infant death, focusing on genetic causes leading to lethal cardiac arrhythmias, considering both genes encoding ion channels as well as structural proteins due to recent association of channelopathies and desmosomal genes. We support a comprehensive analysis of all genes associated with sudden cardiac death in families suffering of infant death. It allows the identification of the most plausible cause of death but also of family members at risk, providing cardiologists with essential data to adopt therapeutic preventive measures in families affected with this lethal entity.

Breastfeeding and dummy use have a protective effect on sudden infant death syndrome

We conducted a literature review on the effect of breastfeeding and dummy (pacifier) use on sudden infant death syndrome (SIDS). From 4343 abstracts, we identified 35 relevant studies on breastfeeding and SIDS, 27 on dummy use and SIDS and 59 on dummy use versus breastfeeding.

Conclusion

We found ample evidence that both breastfeeding and dummy use reduce the risk of SIDS. There has been a general reluctance to endorse dummy use in case it has a detrimental effect of breastfeeding. However, recent evidence suggests that dummy use might not be as harmful to breastfeeding as previously believed.

Exploring caregiver behavior and knowledge about unsafe sleep surfaces in infant injury death cases

OBJECTIVES

In the United States, infant deaths due to sleep-related injuries have quadrupled over the past two decades. One of the major risk factors is the placement of an infant to sleep on a surface other than a crib or bassinet. This study examines contextual circumstances and knowledge and behaviors that may contribute to the placement of infants on an unsafe sleep surface in infant injury death cases.

METHOD

This study employed a retrospective review of 255 sleep-related injury death cases in New York City from 2004 to 2010 where an infant was found sleeping on an unsafe sleep surface. Mixed-methods analyses, employing both quantitative analysis of vital statistics data and risk variables extracted from the medical examiner files and qualitative analysis of the narrative content of the files, were conducted.

RESULTS

In 48% of cases, a crib or bassinet was identified in the home. Quantitative analysis revealed no significant differences in demographic or risk factor characteristics between infants who had a crib or bassinet and those who did not. Qualitative analysis highlighted factors in caregivers' decision making related to situational convenience, preference, and misconceptions concerning safe infant sleep. The health belief model (HBM), specifically the constructs of perceived susceptibility, severity, benefits, and barriers, was used as a lens to understand factors associated with caregiver behavior.

CONCLUSIONS

This study provides evidence that infants are at risk of sleep-related injury death even when a crib or bassinet is present. Understanding the factors that may influence safe sleep behaviors can help produce more appropriate interventions.

Dummy (pacifier) use and sudden infant death syndrome: potential advantages and disadvantages

The large decline in deaths due to the sudden infant death syndrome (SIDS) in the last 20 years in many countries is largely due to risk-reduction advice resulting from observational studies that examined the relationship between infant care practices and SIDS. Most of this advice remains largely uncontroversial and educators and researchers in this field are in agreement as to the specific recommendations that should be given to parents and health professionals. However, advice surrounding the apparent protective effect of dummies (also known as pacifiers) has been controversial. Several systematic reviews have demonstrated a strong association between the lack of a pacifier being used by the infant for the final sleep and SIDS, but it is not clear how pacifiers confer protection or if this is a marker for something as yet unmeasured. The Epidemiology and Physiology Working Groups of the International Society for the Study and Prevention of Perinatal and Infant Death (ISPID) are comprised of leading SIDS researchers with an objective to provide evidence-based position statements surrounding the factors associated with SIDS (http://www.ispid.org/) and risk-reduction strategies. The evidence, discussion and conclusions from these working groups regarding dummies (pacifiers) are described below to help inform this debate and describe the future evidence required so that we might find a common recommendation about dummies (pacifiers) and SIDS.

Conduct of pediatricians in relation to the oral health of children

OBJECTIVE: Pediatricians are health professionals who treat the child during the first years of their life. The purpose of this study was to evaluate the conduct adopted by pediatricians regarding the oral health of children. METHOD: This was a descriptive cross-sectional observational study with a sample of 100 physicians specialized in pediatrics, working in the public and private sectors. A questionnaire was used for data collection, and the pediatricians were approached in their workplaces. RESULT: Most pediatricians (69%) belong to the female gender, with an average age of 48 years, and work in both the public and private sectors of health and have over 20 years of professional experience. Regarding their level of knowledge on oral health, 59% consider it to be good and 59% said that they had not been approached about this issue during their training in pediatrics. Ninety-two percent routinely examine the oral cavity of the baby; 64% recommend the use of fluoridated toothpaste, and 66.7% direct patients to a dental appointment in the first year of life. Regarding breastfeeding at night, 55.6% do not make the association between breastfeeding and the onset of early childhood caries. Furthermore, 74.7% do not justify the associations between the eruption of the first primary teeth and systemic manifestations, and 93% contraindicate the use of a dummy. CONCLUSION: It was concluded that pediatricians have proactive attitudes with regards to oral health. However, they need more information on the importance of fluoride for the control of dental caries

Sudden infant death syndrome: an update

Based on strong research evidence: All infants should be placed in the supine position for every sleep. Tobacco exposure pre- and postnatally should be avoided. Room sharing without bed sharing is recommended. It is recommended that blankets, pillows, and other soft bedding be removed from the infant sleep area. Overheating should be avoided. Breastfeeding should be encouraged for SIDS risk reduction. Pacifier use should be encouraged for SIDS risk reduction. Immunizations should be encouraged for SIDS risk reduction. The evidence for fan use or swaddling as strategies to reduce the risk of SIDS is inconclusive.
