Asphyxiated Neonates Treated with Hypothermia: Birth Place Matters.

OBJECTIVE: This study aimed to assess whether the hospital level of care where asphyxiated neonates treated with hypothermia were originally born influences their outcome. STUDY DESIGN: We conducted a retrospective cohort study of all asphyxiated neonates treated with hypothermia in a large metropolitan area. Birth hospitals were categorized based on provincially predefined levels of care. Primary outcome was defined as death and/or brain injury on brain magnetic resonance imaging (adverse outcome) and was compared according to the hospital level of care. RESULTS: The overall incidence of asphyxiated neonates treated with hypothermia significantly decreased as hospital level of care increased: 1 per 1,000 live births (109/114,627) in level I units; 0.9 per 1,000 live births (73/84,890) in level II units; and 0.7 per 1,000 live births (51/71,093) in level III units (p < 0.001). The rate of emergent cesarean sections and the initial pH within the first hour of life were significantly lower in level I and level II units compared with level III units (respectively, p < 0.001 and p = 0.002). In a multivariable analysis adjusting for the rates of emergent cesarean sections and initial pH within the first hour of life, being born in level I units was confirmed as an independent predictor of adverse outcome (adjusted odds ratio [OR] level I vs. level III 95% confidence interval [CI]: 2.13 [1.02-4.43], p = 0.04) and brain injury (adjusted OR level I vs. level III 95% CI: 2.41 [1.12-5.22], p = 0.02). CONCLUSION: Asphyxiated neonates born in level I units and transferred for hypothermia treatment were less often born by emergent cesarean sections, had worse pH values within the first hour of life, and had a higher incidence of adverse outcome and brain injury compared with neonates born in level III units. Further work is needed to optimize the initial management of these neonates to improve outcomes, regardless of the location of their hospital of birth. KEY POINTS: · The incidence of asphyxiated neonates treated with hypothermia varied by hospital level of care.. · Their rates of emergent cesarean sections and their initial pH within the first hour of life varied by hospital level of care.. · The hospital level of care was an independent predictor of their adverse outcome, defined as death and/or brain injury on brain MRI..

Nasal Intermittent Positive Pressure Ventilation versus Continuous Positive Airway Pressure and Apnea of Prematurity: A Systematic Review and Meta-Analysis.

OBJECTIVE: The study aimed to systematically review and analyze the impact of nasal intermittent positive pressure ventilation (NIPPV) versus continuous positive airway pressure (CPAP) on apnea of prematurity (AOP) in preterm neonates. STUDY DESIGN: In this systematic review and meta-analysis, experimental studies enrolling preterm infants comparing NIPPV (synchronized, nonsynchronized, and bi-level) and CPAP (all types) were searched in multiple databases and screened for the assessment of AOP. Primary outcome was AOP frequency per hour (as defined by authors of included studies). RESULTS: Out of 4,980 articles identified, 18 studies were included with eight studies contributing to the primary outcome. All studies had a high risk of bias, with significant heterogeneity in definition and measurement of AOP. There was no difference in AOPs per hour between NIPPV versus CPAP (weighted mean difference = -0.19; 95% confidence interval [CI]: -0.76 to 0.37; eight studies, 456 patients). However, in a post hoc analysis evaluating the presence of any AOP (over varying time periods), the pooled odds ratio (OR) was lower with NIPPV (OR: 0.46; 95% CI: 0.32-0.67; 10 studies, 872 patients). CONCLUSION: NIPPV was not associated with decrease in AOP frequency, although demonstrated lower odds of developing any AOP. However, definite recommendations cannot be made based on the quality of the published evidence. KEY POINTS: · AOP is a common clinical complication related to preterm birth.. · NIPPV is often used to mitigate AOP and complications.. · Relative impact of NIPPV and CPAP on AOP remains unclear..

Thyroid Storm in a Toddler Presenting as a Febrile Seizure.

Although simple febrile seizures are relatively common and benign in toddlers, it is important to rule out any underlying critical disease that necessitates further intervention and treatment. Thyroid storm, the extreme manifestation of hyperthyroidism, is relatively rare and not often considered in the differential diagnosis of a febrile seizure despite its high mortality rate. Here, we report 1 of the youngest patients with thyroid storm, who initially presented with a febrile seizure. After reevaluation, the 2-year-9-month-old patient was discovered to have thyromegaly, which led to recognition that her persistent tachycardia and widened pulse pressure were likely signs of thyrotoxicosis. Laboratory results were consistent with primary hyperthyroidism due to Graves' disease. Thyroid storm was then diagnosed on the basis of clinical features including gastrointestinal and central nervous system disturbances. Treatment with methimazole, propranolol, hydrocortisone, and Lugol's iodine solution was used. This medication regimen was safe and effective with restoration of a euthyroid state after 2 months and no recurrence of seizures. Improved awareness of hyperthyroidism and thyroid storm can lead to prompt diagnosis and treatment of this endocrine emergency, thus reducing mortality and morbidity. Pediatricians should consider this diagnosis in children with febrile seizures and suggestive vital signs and physical examination findings.

The Steinberg Centre for Simulation and Interactive Learning at McGill University.

Simulation allows for learner-centered health professions training by providing a safe environment to practice and make mistakes without jeopardizing patient care. It was with this goal in mind that the McGill Medical Simulation Center was officially opened on September 14, 2006, as a partnership between McGill University, the Faculty of Medicine and its affiliated hospitals. Its mandate is to provide state-of-the-art facilities to support simulation-based medical and allied health education initiatives. Since its inception, the center, recently renamed the Steinberg Center for Simulation and Interactive Learning (SCSIL), has undergone a major expansion and logged more than 130,000 learner visits. Educational activities are offered at all levels of medical and allied health care training, and include standardized patient encounters, partial task trainers, multidisciplinary courses, and high-fidelity trainers, among many others. In addition to its educational mandate, the center also supports an active research program, programs to enhance collaboration with disciplines outside of health care to spur innovation, and community outreach initiatives.
