panayiotopoulos syndrome a benign childhood autonomic epilepsy frequently imitating encephalitis syncope migraine Sleep Disorder or gastroenteritis
Pediatrics, 2006Co-Authors: Athanasios CovanisAbstract:BACKGROUND. Panayiotopoulos syndrome is a common idiopathic childhood-specific seizure Disorder formally recognized by the International League Against Epilepsy. An expert consensus has defined Panayiotopoulos syndrome as “a benign age-related focal seizure Disorder occurring in early and mid-childhood. It is characterized by seizures, often prolonged, with predominantly autonomic symptoms, and by an EEG [electroencephalogram] that shows shifting and/or multiple foci, often with occipital predominance.” OBJECTIVE. The purpose of this review is to provide guidance for appropriate diagnosis and management of Panayiotopoulos syndrome. CLINICAL FEATURES. Autonomic epileptic seizures and autonomic status epilepticus are the cardinal manifestations of Panayiotopoulos syndrome. Autonomic seizures in Panayiotopoulos syndrome consist of episodes of disturbed autonomic function with emesis as the predominant symptom. Other autonomic manifestations include pallor (or, less often, flushing or cyanosis), mydriasis (or, less often, miosis), cardiorespiratory and thermoregulatory alterations, incontinence of urine and/or feces, hypersalivation, and modifications of intestinal motility. In approximately one fifth of the seizures the child becomes unresponsive and flaccid (ictal syncope) before or often without convulsions. Cardiorespiratory arrest is exceptional. More-conventional seizure symptoms often appear after the onset of autonomic manifestations. The child, who was initially fully conscious, becomes confused and unresponsive. Eyes turn to one side or gaze widely open. Only half of the seizures end with brief hemiconvulsions or generalized convulsions. Convulsive status epilepticus is extremely rare. Autonomic symptoms may be the only features of the seizures. Half of the seizures in Panayiotopoulos syndrome last for >30 minutes, thus constituting autonomic status epilepticus, which is the more common nonconvulsive status epilepticus in normal children. Two thirds of seizures occur during Sleep. EPIDEMIOLOGY. Panayiotopoulos syndrome probably affects 13% of children aged 3 to 6 years who have had 1 or more afebrile seizures and 6% of such children in the 1- to 15-year age group. DIAGNOSTIC TESTS. An electroencephalogram is the only investigation with abnormal results, usually showing multiple spikes in various brain locations. PATHOPHYSIOLOGY. Panayiotopoulos syndrome is probably the early-onset and Rolandic epilepsy the late-onset phenotype of a maturation-related benign childhood seizure-susceptibility syndrome. Ictal epileptic discharges in Panayiotopoulos syndrome, irrespective of their location at onset, activate autonomic disturbances and emesis, to which children are particularly vulnerable. The symptoms/sequence of autonomic seizures and autonomic status epilepticus in Panayiotopoulos syndrome are specific to childhood, and they do not occur in adults. PROGNOSIS. Panayiotopoulos syndrome is remarkably benign in terms of seizure frequency and evolution. Autonomic status epilepticus imparts no residual neurologic deficit. The risk of epilepsy in adult life seems to be no higher than in the general population. However, autonomic seizures are potentially life-threatening in the rare context of cardiorespiratory arrest, an area in which additional study is required. MISDIAGNOSIS. The clinical features of Panayiotopoulos syndrome are frequently mistaken as nonepileptic conditions such as acute encephalitis, syncope, migraine, cyclic vomiting syndrome, motion sickness, Sleep Disorder, or gastroenteritis. The consequence is avoidable misdiagnosis, high morbidity, and costly mismanagement. MANAGEMENT. Education about Panayiotopoulos syndrome is the cornerstone of management. Prophylactic treatment with antiepileptic medication may not be needed for most patients. Autonomic status epilepticus in the acute stage needs thorough evaluation; aggressive treatment may cause iatrogenic complications including cardiorespiratory arrest.

relationships between nutritional knowledge obesity and Sleep Disorder severity
Journal of Sleep Research, 2016Co-Authors: Shiho Rose, Jeffrey J Pretto, Christine L Paul, Brooke Emmett, M J Hensley, Frans HenskensAbstract:Obstructive Sleep apnea affects 20% of the adult population. Weight control is considered the best non-medical means of managing the condition, therefore improving nutritional knowledge in individuals may be an appropriate strategy. This study aimed to describe the relationship between nutritional knowledge and: (i) Sleep Disorder severity; (ii) body mass index; and (iii) demographic characteristics in persons suspected of obstructive Sleep apnea. Nutrition knowledge scores were also compared with the general population. Consecutive newly-referred patients attending the Sleep laboratory for diagnostic polysomnography were invited to participate. Those who consented (n = 97) were asked to complete a touchscreen survey. Apnea-hypopnea index to measure Sleep Disorder severity and anthropometric measurements were obtained from the clinic. A quarter of participants were diagnosed with severe obstructive Sleep apnea; and a majority (88%) were classed as being overweight or obese. The overall mean nutrition knowledge score was 58.4 ± 11.6 (out of 93). Nutrition knowledge was not associated with Sleep Disorder severity, body mass index or gender. The only significant difference detected was in relation to age, with older (≥35 years) participants demonstrating greater knowledge in the 'food choices' domain compared with their younger counterparts (18-34 years; P < 0.030). Knowledge scores were similar to the general population. The findings suggest that nutrition knowledge alone is not an important target for weight control interventions for people with obstructive Sleep apnea. However, given the complexities of Sleep Disorders, it may complement other strategies.

relationships between nutritional knowledge obesity and Sleep Disorder severity
European Respiratory Journal, 2014Co-Authors: Shiho Rose, Jeffrey J Pretto, Brooke Emmett, M J Hensley, Frans Henskens, Chris PaulAbstract:There is a causal relationship between obesity and Sleep-Disordered breathing (SDB) and weight loss is a recommended intervention. Nutrition knowledge (NK) allows healthy dietary choices and may assist in weight loss strategies; however this has not been assessed in the Sleep Disorders population. Aims: To document nutrition knowledge of patients assessed for suspected Sleep Disorders, and to assess relationships between NK, obesity and SDB. Methods: Adult patients attending a Sleep laboratory for polysomnography (PSG) completed a nutrition knowledge questionnaire (Hendrie et al, Pub Health Nutr, 2008;11:1365). Relationships between NK and anthropometric and PSG data were evaluated. Results: 97 patients completed the study with mean (SD) age of 48 (16). 65% were obese, and mean BMI was 34.8 (10.2). The mean AHI (AASMalt) was 17.8 (23.2). Score for overall NK was not different between sexes (t-test p=0.34) and was not correlated with BMI, waist or neck circumference, nor with AHI. There was a single moderate correlation between one domain of NK (everyday food choice) and BMI (r=0.204, p=0.027). Discussion: Nutrition knowledge in this patient cohort is no worse than that of the general Australian community suggesting that lack of NK does not explain the high level of obesity in this group. The overall lack of relationship between NK and severity of SDB or obesity suggests that knowledge deficit is not a contributory cause of obesity or SDB in this cohort. Nutritional knowledge in this group does not seem to determine dietary behaviour. These data suggest that providing education to improve knowledge of diet and nutrition may not be effective as a weight loss strategy for the management of SDB.

shift work and shift work Sleep Disorder clinical and organizational perspectives
Chest, 2017Co-Authors: Emerson M Wickwire, Christopher L Drake, Jeanne Geigerbrown, Steven M ScharfAbstract:Throughout the industrialized world, nearly one in five employees works some form of nontraditional shift. Such shift work is associated with numerous negative health consequences, ranging from cognitive complaints to cancer, as well as diminished quality of life. Furthermore, a substantial percentage of shift workers develop shift work Disorder, a circadian rhythm Sleep Disorder characterized by excessive Sleepiness, insomnia, or both as a result of shift work. In addition to adverse health consequences and diminished quality of life at the individual level, shift work Disorder incurs significant costs to employers through diminished workplace performance and increased accidents and errors. Nonetheless, shift work will remain a vital component of the modern economy. This article reviews seminal and recent literature regarding shift work, with an eye toward real-world application in clinical and organizational settings.

Sleep Disorders and work performance findings from the 2008 national Sleep foundation Sleep in america poll
Journal of Sleep Research, 2011Co-Authors: Leslie M Swanson, Todd J Arnedt, Mark R Rosekind, Gregory Belenky, Thomas J Balkin, Christopher L DrakeAbstract:Chronic Sleep deprivation is common among workers, and has been associated with negative work outcomes, including absenteeism and occupational accidents. The objective of the present study is to characterize reciprocal relationships between Sleep and work. Specifically, we examined how Sleep impacts work performance and how work affects Sleep in individuals not at‐risk for a Sleep Disorder; assessed work performance outcomes for individuals at‐risk for Sleep Disorders, including insomnia, obstructive Sleep apnea (OSA) and restless legs syndrome (RLS); and characterized work performance impairments in shift workers (SW) at‐risk for shift work Sleep Disorders relative to SW and day workers. One‐thousand Americans who work 30 h per week or more were asked questions about employment, work performance and Sleep in the National Sleep Foundation's 2008 Sleep in America telephone poll. Long work hours were associated with shorter Sleep times, and shorter Sleep times were associated with more work impairments. Thirty‐seven percent of respondents were classified as at‐risk for any Sleep Disorder. These individuals had more negative work outcomes as compared with those not at‐risk for a Sleep Disorder. Presenteeism was a significant problem for individuals with insomnia symptoms, OSA and RLS as compared with respondents not at‐risk. These results suggest that long work hours may contribute to chronic Sleep loss, which may in turn result in work impairment. Risk for Sleep Disorders substantially increases the likelihood of negative work outcomes, including occupational accidents, absenteeism and presenteeism.

shift work Sleep Disorder is associated with an attenuated brain response of sensory memory and an increased brain response to novelty an erp study
Sleep, 2010Co-Authors: Valentina Gumenyuk, Thomas Roth, Oleg Korzyukov, Catherine Jefferson, Ashley Kick, Laura Spear, Norman Tepley, Christopher L DrakeAbstract:THE OBJECTIVE ASSESSMENT OF THE CONSEQUENCES OF SleepINESS ON COGNITIVE FUNCTIONS IS PARTICULARLY RELEVANT IN THE MANAGEMENT OF shift work. Shift work has been shown to impair performance on variety of tasks as well as quality of work across different occupations.1,2 In contrast to the literature regarding cognitive function in shift work, evidence for the impact of shift work as well as shift work Sleep Disorder (SWSD) on neurophysiological measures of brain function is limited. SWSD is prevalent3 and is diagnosed when clinically significant symptoms of insomnia and/or excessive Sleepiness are present in shift workers and cannot be accounted for by another Sleep Disorder or medical condition (ICSD-2, 2005). Exposures to major circadian and homeostatic challenges affect cognition in patients with SWSD. However, there have been no studies assessing neurophysiological aspects of brain function specifically related to attention and memory that may occur in conjunction with SWSD. Excessive Sleepiness is the main symptom reported by night shift workers, in part, because their daytime Sleep is fragmented and can be reduced by 2–4 h.2,4 Since Sleep loss leads to deficits in brain functioning,5 it is possible that significant Sleep disturbance in night shift workers may alter activity of neuronal circuitry underlying their attention and memory. The major misalignment of circadian rhythms associated with shift work also contributes to cognitive deficits. The neurophysiology of the attention system can be evaluated by the P300 component of event-related brain potentials (ERP). More specifically, changes in attention can be assessed with the P3a component that reflects the involuntary switching of attention toward an attention-eliciting event, for example, a novel sound such as a dog barking or a car horn.6–8 It has been shown that the prefrontal cortex is a critical element of the neural circuitry that generates the P3a. However, there is strong evidence for a distributed network of cortical regions generating the P3a including the auditory cortex,9 posterior hippocampus,10 temporoparietal junction,11 and anterior cingulate gyrus.12 ERP findings from previous studies looking at the relationship between neural system underlying the P3a and Sleepiness or insomnia13–15 suggest that the P3a response may be useful for assessment of neurophysiological changes in involuntary attention occurring with changes in Sleep-wake function associated with SWSD. For example, it was shown that disturbed Sleep is related to a reduced amplitude of P3a,13 suggesting that an intact involuntary attention switching system reflected by the P3a is critically dependent upon adequate Sleep.15 Another auditory ERP component that has been used widely in Sleep research is mismatch negativity (MMN). MMN has been used most commonly to assess neurocognitive functions related to auditory sensory memory.16,17 Auditory sensory memory is an automatic process involving transient storage of sensory information arising from incoming acoustic stimuli until they can be integrated with previous stimuli or recalled from memorized auditory events. MMN generation depends on the ability of auditory system to remember attributes of frequently presented sounds and thus provides a noninvasive measure of sensory memory.18 Whereas the P3a is associated with attention switching to a novel event in an unattended auditory stream, the MMN is associated with pre-attentive initiation of an attention switch to deviant sounds.18 Importantly, MMN is an involuntary electrical brain response and therefore can be elicited independent of voluntary attention. Thus, MMN provides an unbiased estimate of sensory memory processing without the influence of an individual's motivation or cooperation. It has been shown that excessive Sleepiness is associated with reduced amplitude of MMN at frontal and central brain regions, but not at temporal locations.19,20 Studies indicate that the fontal lobe subcomponent of MMN associated with initiation of an automatic attention switch might be more sensitive to Sleepiness than the temporal lobe MMN component that originates from auditory cortices, which in turn reflects sensory-memory function.18–21 These data are consistent with neuroimaging data that show a reduction of frontal lobe activity following Sleep deprivation.5 In addition, these data suggest that both MMN and P3a brain responses are potentially useful tools for the study of neurophysiological changes in attention and memory function in SWSD. Although the frontal subcomponents of MMN and P3a are related to attention switching, there are critical differences between them. The frontal subcomponent of MMN is associated with pre-attentive initiation of an attention switch to deviant sounds, whereas the P3a frontal-central component reflects attention switching to novel events in an unattended auditory stream.18 The current study uses these auditory ERP measures to evaluate the impact of SWSD on the neurophysiology of memory and attention. In addition to assessing the differences in MMN and P3a associated with night work, we also compared data from the night workers to a control group of day workers assessed using the same tasks.

shift work Sleep Disorder prevalence and consequences beyond that of symptomatic day workers
Journal of Clinical Sleep Medicine, 2005Co-Authors: Christopher L Drake, Thomas Roth, Timothy Roehrs, Gary S Richardson, James K WalshAbstract:Study Objectives: Although there are considerable data demonstrating the impact of shift work on Sleep and alertness, little research has examined the prevalence and consequences of shift work Sleep Disorder in comparison to the difficulties with insomnia and excessive Sleepiness experienced by day workers. The present study was designed to determine the relative prevalence and negative consequences associated with shift work Sleep Disorder in a representative sample drawn from the working population of metropolitan Detroit. Design: Random-digit dialing techniques were used to assess individuals regarding their current work schedules and a variety of Sleep- and non-Sleep-related outcomes. Setting: Detroit tricounty population. Participants: A total of 2,570 individuals aged 18 to 65 years from a representative community-based sample including 360 people working rotating shifts, 174 people working nights, and 2036 working days. Measurements and Results: Using standardized techniques, individuals were assessed for the presence of insomnia and excessive Sleepiness, based on DSM-IV and ICSD criteria. Those individuals with either insomnia or excessive Sleepiness and who were currently working rotating or night schedules were classified as having shift work Sleep Disorder. Occupational, behavioral, and health-related outcomes were also measured. Individuals who met criteria for shift work Sleep Disorder had significantly higher rates of ulcers (odds ratio = 4.18, 95% confidence interval = 2.00-8.72), Sleepiness-related accidents, absenteeism, depression, and missed family and social activities more frequently compared to those shift workers who did not meet criteria (P <.05). Importantly, in most cases, the morbidity associated with shift work Sleep Disorder was significantly greater than that experienced by day workers with identical symptoms. Conclusion: These findings suggest that individuals with shift work Sleep Disorder are at risk for significant behavioral and health-related morbidity associated with their Sleep-wake symptomatology. Further, it suggests that the prevalence of shift work Sleep Disorder is approximately 10% of the night and rotating shift work population.
