Pediatric Functional Movement Disorders: Experience from a Tertiary Care Centre.

OBJECTIVES: Functional movement disorders (FMDs) pose significant diagnostic and management challenges. We aimed to study the socioeconomic and cultural factors, underlying psychopathology and the phenomenology of FMDs in children. METHODS: The study is a retrospective chart review of 39 children (16 girls and 23 boys) who attended our neurology OPD and the movement disorders clinic at the National Institute of Mental Health and Neurosciences (NIMHANS) between January 2011 and May 2020. The diagnosis of FMD was based on Fahn and Williams criteria and the patients were either diagnosed as "documented" or "clinically established". All the relevant demographic data including the ethnicity, socioeconomic and cultural background, examination findings, electrophysiological, and other investigations were retrieved from the medical records. RESULTS: The mean age at onset was 12.69 ± 3.13 years. Majority of the children were from urban regions (56.41%) and belonging to low socioeconomic status (46.15%). Thirty (76.92%) were found to have a precipitating factor. Myoclonus was the most common phenomenology observed in these patients (30.76%), followed by tremor (20.51%), dystonia (17.94%), and gait abnormality (7.69%). Chorea (5.12%) and tics (2.56%) were uncommon. Tremor (37.5%) and dystonia (18.75%) were more common in girls, whereas myoclonus (39.13%) was more common in boys. CONCLUSIONS: The symptoms of FMD have great impact on the mental health, social, and academic functioning of children. It is important to identify the precipitating factors and associated psychiatric comorbidities in these children as prompt alleviation of these factors by engaging parents and the child psychiatrist will yield better outcomes.

Death in delirious palliative-care patients occurs irrespective of age: A prospective, observational cohort study of 229 delirious palliative-care patients.

OBJECTIVES: Patients with terminal illness are at high risk of developing delirium, in particular, those with multiple predisposing and precipitating risk factors. Delirium in palliative care is largely under-researched, and few studies have systematically assessed key aspects of delirium in elderly, palliative-care patients. METHODS: In this prospective, observational cohort study at a tertiary care center, 229 delirious palliative-care patients stratified by age: <65 (N = 105) and ≥65 years (N = 124), were analyzed with logistic regression models to identify associations with respect to predisposing and precipitating factors. RESULTS: In 88% of the patients, the underlying diagnosis was cancer. Mortality rate and median time to death did not differ significantly between the two age groups. No inter-group differences were detected with respect to gender, care requirements, length of hospital stay, or medical costs. In patients ≥65 years, exclusively predisposing factors were relevant for delirium, including hearing impairment [odds ratio (OR) 3.64; confidence interval (CI) 1.90-6.99; P < 0.001], hypertension (OR 3.57; CI 1.84-6.92; P < 0.001), and chronic kidney disease (OR 4.84; CI 1.19-19.72; P = 0.028). In contrast, in patients <65 years, only precipitating factors were relevant for delirium, including cerebral edema (OR 0.02; CI 0.01-0.43; P = 0.012). SIGNIFICANCE OF RESULTS: The results of this study demonstrate that death in delirious palliative-care patients occurs irrespective of age. The multifactorial nature and adverse outcomes of delirium across all age in these patients require clinical recognition. Potentially reversible factors should be detected early to prevent or mitigate delirium and its poor survival outcomes.

Delirium is associated with an increased morbidity and in-hospital mortality in cancer patients: Results from a prospective cohort study.

OBJECTIVE: Delirium is a frequent complication in advanced cancer patients, among whom it is frequently underdiagnosed and inadequately treated. To date, evidence on risk factors and the prognostic impact of delirium on outcomes remains sparse in this patient population. METHOD: In this prospective observational cohort study at a single tertiary-care center, 1,350 cancer patients were enrolled. Simple and multiple logistic regression models were utilized to identify associations between predisposing and precipitating factors and delirium. Cox proportional-hazards models were used to estimate the effect of delirium on death rate. RESULTS: In our patient cohort, the prevalence of delirium was 34.3%. Delirium was associated inter alia with prolonged hospitalization, a doubling of care requirements, increased healthcare costs, increased need for institutionalization (OR 3.22), and increased mortality (OR 8.78). Predisposing factors for delirium were impaired activity (OR 10.82), frailty (OR 4.75); hearing (OR 2.23) and visual impairment (OR 1.89), chronic pneumonitis (OR 2.62), hypertension (OR 1.46), and renal insufficiency (OR 1.82). Precipitating factors were acute renal failure (OR 7.50), pressure sores (OR 3.78), pain (OR 2.86), and cystitis (OR 1.32). On multivariate Cox regression, delirium increased the mortality risk sixfold (HR 5.66). Age ≥ 65 years and comorbidities further doubled the mortality risk of delirious patients (HR 1.77; HR 2.05). SIGNIFICANCE OF RESULTS: Delirium is common in cancer patients and associated with increased morbidity and mortality. Systematically categorizing predisposing and precipitating factors might yield new strategies for preventing and managing delirium in cancer patients.

A multicenter study of transient global amnesia for the better detection of magnetic resonance imaging abnormalities.

BACKGROUND AND PURPOSE: The detection rate of diffusion-weighted (DWI) hyperintense lesions varies widely in patients with transient global amnesia (TGA). The aim was to examine the association of hyperintense lesions on DWI magnetic resonance imaging (MRI) with patient characteristics, precipitating factors, clinical presentation and MRI settings in patients with TGA. METHODS: In this multicenter retrospective observational study, using the standardized diagnosis entry system of electronic health records of four tertiary medical centers in the Kansai district of Japan, TGA patients (n = 261) who underwent brain MRI within 28 days of onset were examined. When the onset time was unavailable, the discovery time was used. RESULTS: Diffusion-weighted hyperintense lesions were observed in 79 patients (30%). There were no significant differences in age, sex, vascular risk factors, precipitating factors or clinical presentation between patients with and without DWI lesions. The detection rate increased linearly 24 h after onset and then reached a plateau of 60%-80% by 84 h. After 84 h, the detection rate decreased rapidly. In a multivariate logistic regression model, MRI examination 24-84 h after onset (odds ratio 7.00, 95% confidence interval 3.50-13.99) and a thin-slice (≤3 mm) DWI sequence (odds ratio 7.59, 95% confidence interval 3.05-18.88) were independent predictors of DWI lesions. CONCLUSIONS: This study suggests that DWI hyperintense lesions in TGA are not associated with patient characteristics and clinical presentation. Brain MRI examination 24-84 h after onset and thin-slice DWI sequences enhance the detection of DWI lesions in TGA patients.

Precipitating factors of heart failure decompensation, short-term morbidity and mortality in patients attended in primary care.

OBJECTIVE: To evaluate the precipitating factors for heart failure decompensation in primary care and associations with short-term prognosis. Design Prospective cohort study with a 30-d follow-up from an index consultation. Regression models to determine independent factors associated with hospitalisation or death. SETTING: Primary care in ten European countries. Patients Patients with diagnosis of heart failure attended in primary care for a heart failure decompensation (increase of dyspnoea, unexplained weight gain or peripheral oedema). MAIN OUTCOME MEASURES: Potential precipitating factors for decompensation of heart failure and their association with the event of hospitalisation or mortality 30 d after a decompensation. RESULTS: Of 692 patients 54% were women, mean age 81 (standard deviation [SD] 8.9) years; mean left ventricular ejection fraction (LVEF) 55% (SD 12%). Most frequently identified heart failure precipitation factors were respiratory infections in 194 patients (28%), non-compliance of dietary recommendations in 184 (27%) and non-compliance with pharmacological treatment in 157 (23%). The two strongest precipitating factors to predict 30 d hospitalisation or death were respiratory infections (odds ratio [OR] 2.8, 95% confidence interval [CI] (2.4-3.4)) and atrial fibrillation (AF) > 110 beats/min (OR 2.2, CI 1.5-3.2). Multivariate analysis confirmed the association between the following variables and hospitalisation/death: In relation to precipitating factors: respiratory infection (OR 1.19, 95% CI 1.14-1.25) and AF with heart rate > 110 beats/min (OR 1.22, 95% CI 1.10-1.35); and regarding patient characteristics: New York Heart Association (NYHA) III or IV (OR 1.22, 95% CI 1.15-1.29); previous hospitalisation (OR 1.15, 95% CI 1.11-1.19); and LVEF < 40% (OR 1.14, 95% CI 1.09-1.19). CONCLUSIONS: In primary care, respiratory infections and rapid AF are the most important precipitating factors for hospitalisation and death within 30 d following an episode of heart failure decompensation. Key points Hospitalisation due to heart failure decompensation represents the highest share of healthcare costs for this disease. So far, no primary care studies have analysed the relationship between precipitating factors and short term prognosis of heart failure decompensation episodes. We found that in 692 patients with heart failure decompensation in primary care, the respiratory infection and rapid atrial fibrillation (AF) increased the risk of short-term hospital admission or death. Patients with a hospital admission the previous year and a decompensation episode caused by respiratory infection were even more likely to be hospitalized or die within 30 d.

Precipitating Factors for Hospitalization with Heart Failure: Prevalence and Clinical Impact Observations from the Gulf CARE (Gulf aCute heArt failuRe rEgistry).

OBJECTIVE: Despite the expanding burden of heart failure (HF) worldwide, data on HF precipitating factors (PFs) in developing countries, particularly the Middle East, are very limited. We examined PFs in patients hospitalized with acute HF in a prospective multicenter HF registry from 7 countries in the Middle East. METHOD: Data were derived from the Gulf CARE (Gulf aCute heArt failuRe rEgistry) for a prospective, multinational, multicenter study of consecutive patients hospitalized with HF in 47 hospitals in 7 Middle Eastern countries between February 2012 and November 2012. PFs were determined by the treating physician from a predefined list at the time of hospitalization. RESULTS: The study included 5,005 patients hospitalized with acute HF, 2,276 of whom (45.5%) were hospitalized with acute new-onset HF (NOHF) and 2,729 of whom (54.5%) had acute decompensated chronic HF (DCHF). PFs were identified in 4,319 patients (86.3%). The most common PF in the NOHF group was acute coronary syndromes (ACS) (39.2%). In the DCHF group, it was noncompliance with medications (27.8%). Overall, noncompliance with medications was associated with a lower inhospital mortality (OR 0.47; 95% CI 0.28-0.80; p = 0.005) but a higher 1-year mortality (OR 1.43; 95% CI 1.1-1.85; p = 0.007). ACS was associated with higher inhospital mortality (OR 1.84; 95% CI 1.26-2.68; p = 0.002) and higher 1-year mortality (OR 1.62; 95% CI 1.27-2.06; p = 0.001). CONCLUSION: Preventive and therapeutic interventions specifically directed at noncompliance with medications and ACS are warranted in our region.

Predisposing and precipitating risk factors for delirium in palliative care patients.

OBJECTIVE: Delirium is a common complication in palliative care patients, especially in the terminal phase of the illness. To date, evidence regarding risk factors and prognostic outcomes of delirium in this vulnerable population remains sparse. METHOD: In this prospective observational cohort study at a tertiary care center, 410 palliative care patients were included. Simple and multiple logistic regression models were used to identify associations between predisposing and precipitating factors and delirium in palliative care patients. RESULTS: The prevalence of delirium in this palliative care cohort was 55.9% and reached 93% in the terminally ill. Delirium was associated with prolonged hospitalization (p < 0.001), increased care requirements (p < 0.001) and health care costs (p < 0.001), requirement for institutionalization (OR 0.11; CI 0.069-0.171; p < 0.001), and increased mortality (OR 18.29; CI 8.918-37.530; p < 0.001). Predisposing factors for delirium were male gender (OR 2.19; CI 1.251-3.841; p < 0.01), frailty (OR 15.28; CI 5.885-39.665; p < 0.001), hearing (OR 3.52; CI 1.721-7.210; p < 0.001), visual impairment (OR 3.15; CI 1.765-5.607; p < 0.001), and neoplastic brain disease (OR 3.63; CI 1.033-12.771; p < 0.05). Precipitating factors for delirium were acute renal failure (OR 6.79; CI 1.062-43.405; p < 0.05) and pressure sores (OR 3.66; CI 1.102-12.149; p < 0.05). SIGNIFICANCE OF RESULTS: Our study identified several predisposing and precipitating risk factors for delirium in palliative care patients, some of which can be targeted early and modified to reduce symptom burden.

Infection as a Stroke Trigger.

Background and Purpose- The relationships between different infection types and stroke subtype are not well-characterized. We examined exposure to infections in different organ systems in different time periods before the acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. Methods- We used the New York State Inpatient Databases and Emergency Department Databases (2006-2013). Validated International Classification of Diseases, Ninth Edition definitions identified index hospitalizations for acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage, and emergency department visits and hospitalizations for infection (skin, urinary tract infection, septicemia, abdominal, and respiratory). We used case cross-over analysis with conditional logistic regression to estimate odds ratios (OR) for the association between each infection type during case periods compared with control periods 1 year before. Results- Every infection type was associated with an increased likelihood of acute ischemic stroke. The greatest association was for urinary tract infection, with OR of 5.32 (95% CI, 3.69-7.68) within the 7-day window. The magnitude of association between urinary tract infection and intracerebral hemorrhage was of lesser magnitude, with OR of 1.80 (1.04-3.11) in the 14-day exposure period and OR of 1.54 (1.23-1.94) in the 120-day exposure period. Only respiratory infection was associated with subarachnoid hemorrhage, with OR of 3.67 (1.49-9.04) in the 14-day window and 1.95 (1.44-2.64) in the 120-day window. Conclusions- All infection types were associated with subsequent acute ischemic stroke, with the greatest association for urinary tract infection.

The predisposing and precipitating risk factors for delirium in neurosurgery: a prospective cohort study of 949 patients.

BACKGROUND: Delirium is the most common neuropsychiatric presentation during hospitalization. In neurosurgery, studies on predisposing and precipitating risk factors for the development of delirium are rare but required for the individual risk estimation. METHODS: Prospective cohort study in a tertiary university center. In total, 949 neurosurgical patients, 307 with and 642 without delirium, were included. Demographic factors, neurosurgery-related, neurological, and medical clusters were tested as predictors of delirium in multiple logistic regression analyses. RESULTS: The incidence of delirium in this cohort of neurosurgical patients was 32.4%. Compared to patients without delirium, those with delirium were significantly older, more cognitively and neurologically impaired, transferred from hospitals and nursing homes, admitted as emergencies, longer hospitalized (16.2 vs. 9.5 days; p < 0.001), in greater need of intensive care management, and more frequently transferred to rehabilitation. Predisposing factors of delirium were stroke (OR 5.45, CI 2.12-14.0, p < 0.001), cardiac insufficiency (OR 4.59, CI 1.09-19.26, p = 0.038), cerebral neoplasm (OR 1.53, CI 0.92-2.54, p = 0.019), and age ≥ 65 years (OR 1.47, CI 1.03-2.09, p = 0.030). Precipitating factors of delirium were acute cerebral injury (OR 3.91, CI 2.24-6.83, p < 0.001), hydrocephalus (OR 3.10, CI 1.98-4.87, p < 0.001), and intracranial hemorrhage (OR 1.90, CI 1.23-2.94, p = 0.004). CONCLUSIONS: Delirium in acute neurosurgical patients was associated with longer hospitalization. Whereas common etiologies of delirium like infections and dementia, did not predict delirium, pre-existing neurovascular and traumatic diseases, as well as surgery-related events seem important risk factors contributing to delirium in neurosurgery.

5-oxoprolinuria (Pyroglutamic Aciduria) and Metabolic Acidosis: Unraveling the Mystery.

A case of high anion gap metabolic acidosis (HAGMA) and high level of 5-oxoprolinuria were noticed in an elderly female of 66 years who had multiple risk/precipitating factors and recovered well with N-acetyl cysteine infusion. This is reported in view of its rarity and to create awareness of this entity among medical students and practicing physicians who handles such cases in emergency room or critical care unit. Moreover they have to remember and investigate the cases of metabolic acidosis for 5-oxoprolinuia especially in susceptible individuals who are on paracetamol with or without other precipitating factors.

Migraine triggers and habituation of visual evoked potentials.

Background Identifying specific subsets of patients within the clinical spectrum of migraine could help in personalizing migraine treatment. Profiling patients by combining clinical characteristics and neurophysiological biomarkers is largely unexplored. We studied the association between migraine attack triggers and habituation of visual evoked potentials. Methods We personally interviewed 25 patients about their migraine triggers following a structured list, and measured the N1-P1 habituation slope over six blocks of 100 averaged pattern-reversal VEP afterwards. Results The mean number of triggers per patient was 4.52 ± 1.42. Habituation slopes differed significantly between subjects who reported stress as a migraine trigger (deficient VEP habituation) and subjects who did not (preserved VEP habituation). For the remaining categories, the mean amplitude slope was always positive, indicating deficient habituation, and was not significantly different between subgroups. Conclusions Migraine patients not reporting perceived stress as a trigger for their attacks might constitute a distinct clinic-physiological subset within the migraine spectrum.

Association of recent major psychological stress with cardiac arrest: A case-control study.

OBJECTIVE: We hypothesized that major psychological stress can be a risk factor for cardiac arrest and that effects are modified by elapsed time from specific stressful events. METHODS: Case-control study was conducted using database for cardiac arrest and emergency department (ED) visiting. Cases included adult patients with cardiac arrest with presumed cardiac etiology. Controls were matched with sex and age and visiting day from unintentional injured patients in same ED. The occurrence of 9 major life events (MLEs) such as a divorce within 1year was used as a proxy measure of major psychological stress. A multivariable conditional logistic regression conducted to estimate the effect of MLEs on the risk of cardiac arrest according to the elapsed time from the MLEs. RESULTS: A total of 95 patients with cardiac arrest and 95 controls were assessed. In the case group, a total of 58 MLEs occurred, while 33 MLEs occurred in the control group during the same period. Recent MLEs were associated with a higher risk of sudden cardiac arrest (AOR 2.26 [95% CI:1.01-5.03]). The AORs of cardiac arrest were 4.65 (95% CI, 1.38-15.67) and 7.02 (95% CI, 2.03-24.48) among participants experiencing MLEs within the last 0-3months and those experiencing MLEs within the last 0-6months, respectively. Cardiac arrest and MLEs in participants experiencing MLEs between 7 and 12months prior showed no association (AOR 4.76 [95% CI, 0.97-18.36]). CONCLUSIONS: MLEs were associated with cardiac arrest occurrence, and the effect was modified by the elapsed time from the MLEs.

Physical Activity and Anger or Emotional Upset as Triggers of Acute Myocardial Infarction: The INTERHEART Study.

BACKGROUND: Physical exertion, anger, and emotional upset are reported to trigger acute myocardial infarction (AMI). In the INTERHEART study, we explored the triggering association of acute physical activity and anger or emotional upset with AMI to quantify the importance of these potential triggers in a large, international population. METHODS: INTERHEART was a case-control study of first AMI in 52 countries. In this analysis, we included only cases of AMI and used a case-crossover approach to estimate odds ratios for AMI occurring within 1 hour of triggers. RESULTS: Of 12 461 cases of AMI 13.6% (n=1650) engaged in physical activity and 14.4% (n=1752) were angry or emotionally upset in the case period (1 hour before symptom onset). Physical activity in the case period was associated with increased odds of AMI (odds ratio, 2.31; 99% confidence interval [CI], 1.96-2.72) with a population-attributable risk of 7.7% (99% CI, 6.3-8.8). Anger or emotional upset in the case period was associated with an increased odds of AMI (odds ratio, 2.44; 99% CI, 2.06-2.89) with a population-attributable risk of 8.5% (99% CI, 7.0-9.6). There was no effect modification by geographical region, prior cardiovascular disease, cardiovascular risk factor burden, cardiovascular prevention medications, or time of day or day of onset of AMI. Both physical activity and anger or emotional upset in the case period were associated with a further increase in the odds of AMI (odds ratio, 3.05; 99% CI, 2.29-4.07; P for interaction <0.001). CONCLUSIONS: Physical exertion and anger or emotional upset are triggers associated with first AMI in all regions of the world, in men and women, and in all age groups, with no significant effect modifiers.

Weather as a risk factor for epileptic seizures: A case-crossover study.

OBJECTIVE: Most epileptic seizures occur unexpectedly and independently of known risk factors. We aimed to evaluate the clinical significance of patients' perception that weather is a risk factor for epileptic seizures. METHODS: Using a hospital-based, bidirectional case-crossover study, 604 adult patients admitted to a large university hospital in Central Germany for an unprovoked epileptic seizure between 2003 and 2010 were recruited. The effect of atmospheric pressure, relative air humidity, and ambient temperature on the onset of epileptic seizures under temperate climate conditions was estimated. RESULTS: We found a close-to-linear negative correlation between atmospheric pressure and seizure risk. For every 10.7 hPa lower atmospheric pressure, seizure risk increased in the entire study population by 14% (odds ratio [OR] 1.14, 95% confidence interval [CI] 1.01-1.28). In patients with less severe epilepsy treated with one antiepileptic medication, seizure risk increased by 36% (1.36, 1.09-1.67). A high relative air humidity of >80% increased seizure risk in the entire study population by up to 48% (OR 1.48, 95% CI 1.11-1.96) 3 days after exposure in a J-shaped association. High ambient temperatures of >20°C decreased seizure risk by 46% in the overall study population (OR 0.54, 95% CI 0.32-0.90) and in subgroups, with the greatest effects observed in male patients (OR 0.33, 95% CI 0.14-0.74). SIGNIFICANCE: Low atmospheric pressure and high relative air humidity are associated with an increased risk for epileptic seizures, whereas high ambient temperatures seem to decrease seizure risk. Weather-dependent seizure risk may be accentuated in patients with less severe epilepsy. Our results require further replication across different climate regions and cohorts before reliable clinical recommendations can be made.

Characterisation of aggression in Huntington's disease: rates, types and antecedents in an inpatient rehabilitation setting.

AIMS AND OBJECTIVES: To systematically review aggression in an inpatient Huntington's cohort examining rates, types and antecedents. BACKGROUND: Although the prevalence of aggression in Huntington's disease is high, research into this problematic behaviour has been limited. Few studies have investigated the nature of aggressive behaviour in Huntington's disease or antecedents that contribute to its occurrence. DESIGN: A systematic, double-coded, electronic medical file audit. METHODS: The electronic hospital medical records of 10 people with Huntington's disease admitted to a brain disorders unit were audited for a 90-day period using the Overt Aggression Scale-Modified for Neurorehabilitation framework, yielding 900 days of clinical data. RESULTS: Nine of 10 clients exhibited aggression during the audit period. Both verbal (37·1%) aggression and physical aggression were common (33·8%), along with episodes of mixed verbal and physical aggression (15·2%), while aggression to objects/furniture was less prevalent (5·5%). The most common antecedent was physical guidance with personal care, far exceeding any other documented antecedents, and acting as the most common trigger for four of the nine clients who exhibited aggression. For the remaining five clients, there was intraindividual heterogeneity in susceptibility to specific antecedents. CONCLUSION: In Huntington's sufferers at mid- to late stages following disease onset, particular care should be made with personal care assistance due to the propensity for these procedures to elicit an episode of aggression. However, given the degree of intraindividual heterogeneity in susceptibility to specific antecedents observed in the present study, individualised behaviour support plans and sensory modulation interventions may be the most useful in identifying triggers and managing aggressive episodes. RELEVANCE TO CLINICAL PRACTICE: Rates of aggression in Huntington's disease inpatients can be high. Knowledge of potential triggers, such as personal care, is important for nursing and care staff, so that attempts can be made to minimise distress for patients and maximise the personal safety of care staff.

Antecedents of Suicide among Youth Aged 11-15: A Multistate Mixed Methods Analysis.

Suicide is the second leading cause of death for youth aged 11 to 15, taking over 5,500 lives from 2003 to 2014. Suicide among this age group is linked to risk factors such as mental health problems, family history of suicidal behavior, biological factors, family problems, and peer victimization and bullying. However, few studies have examined the frequency with which such problems occur among youth suicide decedents or the context in which decedents experience these risk factors and the complex interplay of risk that results in a decedent's decision to take his/her own life. Data from a random sample of 482 youth (ages 11-15) suicide cases captured in the National Violent Death Reporting System from 2003 to 2014 were analyzed. The sample had fewer girls than boys (31 vs. 69 %) and comprised primarily White youth (79 %), but also African Americans (13 %), Asians (4 %), and youth of other races (4 %). Narrative data from coroner/medical examiner and law enforcement investigative reports were coded and analyzed to identify common behavioral patterns that preceded suicide. Emergent themes were quantified and examined using content and constant comparative analysis. Themes regarding antecedents across multiple levels of the social ecology emerged. Relationship problems, particularly with parents, were the most common suicide antecedent. Also, a pattern demonstrating a consistent progression toward suicidal behavior emerged from the data. Narratives indicated that youth were commonly exposed to one or more problems, often resulting in feelings of loneliness and burdensomeness, which progressed toward thoughts and sometimes plans for or attempts at suicide. Continued exposure to negative experiences and thoughts/plans about suicide, and/or self-injurious acts resulted in an acquired capacity to self-harm, eventually leading to suicide. These findings provide support for theories of suicidal behavior and highlight the importance of multi-level, comprehensive interventions that address individual cognitions and build social connectedness and support, as well as prevention strategies that increase awareness of the warning signs and symptoms of suicide, particularly among family members of at-risk youth.

[Assessment to carry out with a patient who has suffered a fall]. / Bilan à réaliser devant un patient chuteur.

A fall in an elderly person can lead to severe complications. It is a serious event which must not be minimised in any way and which must serve as a warning signal for the caregiver. The exploration of the factors involved requires a detailed and comprehensive evaluation of the patient. A complete assessment coordinated by a geriatric doctor is recommended.

Reliability of assessing lifestyle and trigger factors in patients with migraine--findings from the PAMINA study.

BACKGROUND AND PURPOSE: Numerous lifestyle factors are blamed for triggering migraine attacks. The reliability of assessing these factors retrospectively is unknown. Therefore, retrospective and prospective assessments of lifestyle in general and of migraine triggers in particular were compared in patients with migraine. METHODS: At baseline, the patients filled in two questionnaires covering the previous 90 days. Thereafter they kept a prospective 90-day diary. Questionnaires and diary included the same set of 45 factors. In the first questionnaire the patients assessed their lifestyle, in the second they rated for each factor the likelihood of triggering a migraine attack, and in the diary they recorded the daily presence of these factors irrespective of headache. Five categories were used for comparing frequencies in questionnaire and diary, defining agreement as identical categories in diary and questionnaire, minor disagreement and major disagreement as overestimation or underestimation by one category and two or more categories, respectively. RESULTS: In all, 327 patients (283 women, age 41.9 ± 12.1 years) who recorded 28,325 patient days were included. Calculating for each factor the percentage of patients with major disagreement the mean proportion was larger for trigger factors than for lifestyle (38.7% ± 6.6% vs. 16.9% ± 6.4%, P < 0.001). The proportion of factors showing major disagreement in more than 20% of the patients was 8.8% for lifestyle but 94.1% for trigger factors (P < 0.001). CONCLUSION: Comparing questionnaire and diary assessments of lifestyle and trigger factors in patients with migraine shows that questionnaire assessment of lifestyle is reliable, whereas trigger factors are overestimated and/or underestimated in retrospective questionnaires.

Status epilepticus in patients with juvenile myoclonic epilepsy: Frequency, precipitating factors and outcome.

Status epilepticus (SE) is rarely described in patients with juvenile myoclonic epilepsy (JME), and little is known about its frequency, subtypes, and predictors and the prognosis of these patients. In this retrospective study, we aimed to analyze the incidence of SE in patients with JME and emphasize the risk factors and long-term outcome of SE in an epilepsy outpatient-based cohort. We included patients with JME with a history of predominant myoclonic seizures and at least one diagnostic EEG with normal background activity and bursts of typical ≥3-Hz generalized spike-polyspike and waves. We investigated the electroclinical features of patients with JME who had experienced SE and compared them with patients with JME without SE. Of the 133 patients with JME, only 5 patients were diagnosed with SE (3.8%) according to new criteria. The most common SE subtype was myoclonic SE (MSE, 4 patients), followed by generalized clonic-tonic-clonic SE (1 patient) and nonconvulsive SE (1 patient). One patient had both MSE and generalized clonic-tonic-clonic SE. In three out of five patients, recurrent episodes of SE were observed. Same seizure precipitants including sleep deprivation, inappropriate antiepileptic drug treatment, and noncompliance were identified in patients with JME with and without SE, not reaching a significant difference between the groups. Myoclonia limited to specific body parts (one arm, face, or head) were significantly more common in patients with JME with SE (p: 0.002). We did not find any significant correlation with drug-resistant course and SE. Status epilepticus is rarely observed in patients with JME, and MSE appears to be the most common subtype. Local myoclonia might predict SE in a subgroup of patients with JME. We may suggest that some patients with JME have a liability to SE, in addition to usual seizure precipitating factors of JME. It seems that SE per se does not affect the outcome of JME and the patients with SE did not have drug-resistant course in the final analysis.
