Outcome Following Carbon Monoxide Poisoning in Children

Carbon Monoxide Poisoning

Carbon monoxide poisoning is common. Many adults with CO poisoning have long-term, even permanent brain injury following poisoning. However, very little is known about the long-term outcome of children with carbon monoxide (CO) poisoning. In this study we plan to perform cognitive (thinking) and vestibular (balance) testing in children (ages 6 to 16)at 6 weeks and 6 months following CO poisoning. At the 6-week visit, if the child and parents agree, we will ask each child to provide a DNA sample by one of three methods: mouthwash, spit collection, or swabbing the inside of the child's cheek. Each child's DNA will be analyzed for genes that are known to affect outcome following brain injury.

Health Professions Students and Faculty Perceptions of Poisoning Severity

Poisoning

Inaccurate perceptions of the severity of an exposure may result in unnecessary visits to the Emergency Department or Health Care Facility which can result in crowding of Emergency Departments, unnecessary utilization of valuable health care resources, unnecessary treatments, and or mistakes / errors resulting in harm to the patient. Inaccurate perceptions about the severity of an exposure can result in delays in proper evaluation and treatment resulting in harm or in some cases death of the patient.

Causality of Poisoning of the Elderly: Prospective Study Based on Data From the Poison Control Centre...

Intoxication

Elderly is often associated with social, physiological and psychic changes. However, no study has examined accidental poisoning-induced changes. The objective of the study is to identify and analyze the various causes of potentially toxic accidental exposure of the elderly to determine preventable causes and propose prevention strategies.

Cardiac Magnetic Resonance Image (CMR) in Acute Carbon Monoxide (CO) Poisoning

Carbon Monoxide PoisoningMyocardial Injury2 more

Previous report showed that 37% of patients with moderate to severe carbon monoxide (CO) poisoning experienced a myocardial injury, defined as elevated cardiac enzyme [creatine kinase, CK-MB, and cardiac troponin I (TnI)] or ischemic electrocardiogram (ECG) change. In other study, 24% of the patients with the myocardial injury after CO poisoning died during a median follow-up of 7.6 years. The myocardial injury was the major predictor of mortality. In addition, in the Taiwanese nationwide population-based cohort study, CO poisoning itself reported as a higher risk of a major adverse cardiovascular event. According to the previous study of investigators, among CO poisoned patients with myocardial injury, 74.4% of patients experienced CO-induced cardiomyopathy. All CO-induced cardiomyopathy recovered to normal status. In this situation, there is no definite approved reason why more cardiovascular events are occurred in CO poisoned patients with myocardial injury during long term follow-up period despite normalization of CO-induced elevated TnI and cardiac dysfunction. Two image cases related to cardiac magnetic resonance imaging (CMR) in acute CO poisoning previously reported. One image case reported that patient had mildly depressed left ventricular (LV) systolic function with hypokinesis of the anterior wall and regional akinesis of the inferior wall on the transthoracic echocardiography performed during hospitalization and late gadolinium-enhancement (LGE) images of CMR demonstrated multiple focal areas of high signal consistent with myocardial necrosis or fibrosis. Another image case reported an image case that in CMR, inferolateral mid-wall myocardial fibrosis, which was defined as LGE, was present despite the setting of a completely normal echocardiogram at 4-month follow-up in CO poisoned patients. Therefore, the investigators evaluate prevalence (frequency of LGE positive) and patterns (involved LV wall and range of LGE positive) of myocardial fibrosis (LGE positive) in acute CO-poisoned patients during acute (within seven days after CO exposure) and chronic phase (at 4-5 months after CO exposure) and whether LGE positive developed in acute phase have been changed through cardiac MRI performed at chronic phase. The investigators also evaluate LV ejection fraction and global longitudinal strain in transthoracic echocardiography performed at the ED (baseline) and within seven days (follow-up). The investigators also assessed the association between neurocognitive outcomes using the global deterioration scale (at 1, 6, and 12 months after CO exposure) and the presence of LGE positive.

Quantitative Assessment of Pupillary Light Reflex in Acute Carbon Monoxide Poisoning

Carbon Monoxide Poisoning

Neurological complications after acute carbon monoxide (CO) poisoning can range from transient headache or dizziness to cognitive dysfunction, seizure, permanent anoxic brain damages or death. A recent study reported that a lack of standard pupillary light reflex (sPLR), assessed using a pen light, was a predictor of 30-day neurological sequelae in patients with CO poisoning. Given that the basic sPLR has a poor inter-rater reliability, more objective and quantitative methods are required in the assessment of PLR. An automated pupillometer has been used in the intensive care unit to quantitatively assess the PLR. Therefore, we hypothesized that quantitative assessment of PLR might be associated with neurocognitive sequelae after acute CO poisoning. The purpose of this study was to assess the value of quantitative pupillary reactivity (NPi and qPLR) in comparison to that of sPLR in predicting neurocognitive outcome at 1 month after acute CO poisoning.

Early Exposure to Lead and Adolescent Development

Lead Poisoning

This prospective cohort study examines the role of prenatal and early postnatal lead exposure on the neuropsychological status and social adjustment of adolescents enrolled in the Cincinnati Lead Study. We are examining the relationship between moderate exposure to lead and neuropsychological deficits, difficulties in peer relationships, personality disturbances and juvenile delinquency. This birth cohort of approximately 300 subjects has been followed since 1980 with regularly scheduled assessments of blood lead concentrations, health history, social and hereditary factors, and neurobehavioral development.
