ABSTRACT

BACKGROUND: Diagnosis of lateral medullary syndrome (LMS) is often delayed due to elusive clinical presentations and frequently non-revealing neuroimaging tests. We aimed to investigate the use of ipsilateral vocal cord paresis (VCP) identified on neck computed tomography angiography (CTA) as an early diagnostic sign for LMS. METHODS: Medical records were queried for patients admitted with LMS between 1/2012 and 10/2020. A control group of patients undergoing CTA for transient or no neurological symptoms was matched for sex and age. Clinical data were collected by a stroke neurologist. Two neuroradiologists independently and blindly assessed CTA images for radiological signs of VCP. RESULTS: Fifteen LMS and 15 control patients were included in the analysis. Median time from arrival to LMS diagnosis was 29.4 h [IQR 7,47] and twice as long in patients who suffered aspiration pneumonia. Thrombolysis rate was 0% in LMS patients versus 14.5% in general stroke patients. Dysphonia was noted in the emergency department in three (20%) patients, whereas all 15 patients had radiological signs of VCP on CTA. Medialization of a true vocal cord was the most sensitive (100%) and specific (80-87%) sign for LMS, with good inter-rater agreement (kappa 0.66). Timely detection of VCP on CTA could have shortened median time to LMS diagnosis by 14 h and enabled thrombolytic therapy in 3 (20%) patients. CONCLUSIONS: VCP on CTA is a valuable sign for the diagnosis of LMS. If detected early, it may enable reperfusion therapy and prevent aspiration pneumonia, consequently saving life and diminishing disability.

ABSTRACT

Introduction: Forty percent of young children worldwide are exposed to the harmful effects of tobacco smoke, predominantly by parental smoking. Little is known about why parents regularly expose their children to these risks; perhaps parents underestimate the degree of exposure. Qualitative methods were used to investigate parental perceptions of tobacco smoke exposure. Methods: Sixty-five in-depth interviews were conducted with parents of young children in smoking families in central Israel. Parents were asked to explain what "exposure to smoking" meant. Thematic analysis was performed, a conceptual model of perceptions was built, and misconceptions were identified. Results: Parents reported that exposure occurs when smoke or smokers are visible, when smoke can be smelled, felt, or inhaled, or when it "reaches" an individual. Conversely, some believed that exposure does not occur in the absence of odor, visible smoke, or smokers or if smoking occurs outdoors or in indoor ventilated environments. Proximity in space and time affected perceptions of exposure; some parents believed that smoke does not spread far but dissipates rapidly. There was some uncertainty regarding whether or not exposure was occurring. Conclusions: Awareness of child exposure to tobacco smoke among parents in this study was based on sensory perceptions in the context of the physical environment. The limited capacity of humans to perceive tobacco smoke can lead to misconceptions about exposure. In order to protect children, parents must be convinced that exposure can occur even in situations where they are unable to sense it. Implications: Parents use sensory perceptions (sight, smell, and feel) in the context of the physical environment to assess whether or not their children are exposed to tobacco smoke. Because 85% of smoke is invisible and the sense of smell is unreliable, assessments based on sensory perceptions cannot provide accurate information about the presence of tobacco smoke. In order to protect children, parents must be convinced that exposure can occur even in situations where they are unable to sense it. The scientific information summarized here about exposure in common situations should be useful in persuading parents to protect their children. Clinical Trial Registration: This study is registered as a Phase I study which is part of a larger research endeavor entitled: A program to protect young children from tobacco smoke exposure. Registration number: NCT01335178.

ABSTRACT

BACKGROUND: Vaccine compliance has long been a cause for concern for health authorities throughout the world. However very little effort has been made to examine parental discourse during the decision-making process. METHODS: An online survey was conducted (N = 437) to examine predictors of parents' attitudes regarding childhood vaccination. RESULTS: Hesitant parents were 4 times more likely to conduct intrafamily discussion regarding vaccination compared with provaccination parents (Exp[B] = 4.26). There were no significant differences between hesitant and antivaccination parents with respect to intrafamily discussion. Hesitant parents were also 4 times more likely than provaccination parents to report intrafamily disagreements regarding vaccination (Exp[B] = 4.27). They were also twice as likely as antivaccination parents to express disagreements regarding vaccination within their families (Exp[B] = 2.33). Likewise, Jewish parents were significantly more likely to define themselves as vaccination-hesitant, whereas Muslim parents were significantly more likely to be provaccination. CONCLUSIONS: To improve the way health organizations communicate information about vaccines and increase parental trust in immunization programs, we should not only look at the level of understanding, perceptions, and biases of different groups, but also thoroughly examine parents' decision-making processes and the discourse during this process. We must communicate risk to all groups, including the provaccination group, to improve parents' decision making and the process of informed consent.

ABSTRACT

OBJECTIVE: Widespread tobacco smoke exposure (TSE) of children suggests that parents may be unaware of their children's exposure. Biomarkers demonstrate exposure and may motivate behavior change, but their acceptability is not well understood. METHODS: Sixty-five in-depth interviews were conducted with parents of young children, in smoking families in central Israel. Data were analyzed using thematic analysis. RESULTS: Consent to testing was associated with desire for information, for reassurance or to motivate change, and with concerns for long-term health, taking responsibility for one's child, and trust in research. Opposition to testing was associated with preference to avoid knowledge, reluctance to cause short-term discomfort, perceived powerlessness, and mistrust of research. Most parents expressed willingness to allow measurement by urine (83%), hair (88%), or saliva (93%), but not blood samples (43%); and believed that test results could motivate behavior change. CONCLUSIONS: Parents were receptive to non-invasive child biomarker testing. Biomarker information could help persuade parents who smoke that their children need protection. PRACTICE IMPLICATIONS: Biomarker testing of children in smoking families is an acceptable and promising tool for education, counseling, and motivation of parents to protect their children from TSE. Additionally, biomarker testing allows objective assessment of population-level child TSE.
