Background Suicide has profound effects on families and communities, but is a statistically rare event. Psychological autopsies using a case-control design allow researchers to examine risk factors for suicide, using a variety of sources to detail the psychological and social characteristics of decedents and to compare them to controls. The Suicide Support and Information System Case Control study (SSIS-ACE) aimed to compare psychosocial, psychiatric and work-related risk factors across three groups of subjects: suicide decedents, patients presenting to hospital with a high-risk self-harm episode, and general practice controls. Methods The study design includes two inter-related studies; one main case-control study: comparing suicide cases to general practice (GP) controls, and one comparative study: comparing suicide cases to patients presenting with high-risk self-harm. Consecutive cases of suicide and probable suicide are identified through coroners’ registration of deaths in the defined region (Cork City and County, Ireland) and are frequency-matched for age group and gender with GP patient controls recruited from the same GP practice as the deceased. Data sources for suicide cases include coroners’ records, interviews with health care professionals and proxy informants; data sources for GP controls and for high-risk self-harm controls include interviews with control, with proxy informants and with health care professionals. Interviews are semi-structured and consist of quantitative and qualitative parts. The quantitative parts include a range of validated questionnaires addressing psychiatric, psychosocial and occupational factors. The study adopts several methodological innovations, including accessing multiple data sources for suicide cases and controls simultaneously, recruiting proxy informants to examine consistency across sources. Conclusions The study allows for the investigation of consistency across different data sources and contributes to the methodological advancement of psychological autopsy research. The study will also inform clinical and public health practice. The comparison between suicide cases and controls will allow investigation of risk and protective factors for suicide more generally, while the comparison with high-risk self-harm patients will help to identify the factors associated specifically with a fatal outcome to a self-harm episode. A further enhancement is the particular focus on specific work-related risk factors for suicide.

Background Risk of self-harm repetition has consistently been shown to be higher following self-cutting compared to intentional drug overdose (IDO) and other self-harm methods. The utility of previous evidence is limited due to the large heterogeneous method categories studied. This study examined risk of hospital presented self-harm repetition according to specific characteristics of self-harm methods. Methods Data on consecutive self-harm presentations to hospital emergency departments (2010–2016) were obtained from the National Self-Harm Registry Ireland. Associations between self-harm method and repetition were analysed using survival analyses. Results Overall, 65,690 self-harm presentations were made involving 46,661 individuals. Self-harm methods associated with increased repetition risk included minor self-cutting, severe self-cutting, multiple drug IDOs involving psychotropic drugs and self-harm by blunt object. Minor self-cutting was the method associated with highest repetition risk (adjusted hazard ratio (AHR) 1.38, 95% CI 1.31–1.45). Risk of repetition was comparable following IDOs of four or more drugs involving psychotropic drugs (AHR = 1.29, 95% CI 1.20–1.39), severe self-cutting (AHR 1.25, 95% CI 1.16–1.34) and blunt object (AHR = 1.23, 95% CI 1.07–1.42). Limitations Information was not available on suicide or other causes of mortality. Conclusions Self-harm method and the associated risk of repetition should form a core part of biopsychosocial assessments and should inform follow-up care for self-harm patients. The observed differences in repetition associated with specific characteristics of IDO underline the importance of safety planning and monitoring prescribing for people who have engaged in IDO.

OBJECTIVE: The specific objectives of this study were to examine variation in the care of self-harm patients in hospital settings and to identify the factors that predict recommended next care following self-harm. METHODS: Data on consecutive presentations to Irish emergency departments (EDs) involving self-harm from the National Self-Harm Registry Ireland from 2004 to 2012 were utilised. Univariate and multivariate regression analyses were performed to assess the associations between patients' clinical and demographic characteristics, and recommended next care received. RESULTS: Across the study period a total 101,904 self-harm presentations were made to hospital EDs, involving 63,457 individuals. Intentional drug overdose was the most common method of self-harm, present in 72% of all episodes. Over the course of the study there was a declining number of presentations resulting in patient admission following attendance with self-harm. Recommended next care varied according to hospital location, with general admission rates ranging from 11% to 61% across administrative health regions. Multinomial logistic regression identified that the factor which most strongly affected next care was the presenting hospital. Being male, older age, method, repeat self-harm, time of attendance and residence of the patient were all identified as influencing care received. Psychiatric admission was most common when highly lethal methods of self-harm were used (OR = 4.00, 95% CI, 3.63-4.41). A relatively large proportion of patients left the ED without being seen (15%) and the risk of doing so was highest for self-harm repeaters (1.64, 1.55-1.74 for those with 5+ presentations). CONCLUSIONS: The extensive hospital variation in recommended next care indicates that management of self-harm patients may be determined more by where they present than by the needs of the patient. The study outcomes underline the need to standardise the clinical management of self-harm patients in general hospital settings.

IntroductionWe previously reported that benzodiazepine detoxification for alcohol withdrawal using symptom-triggered therapy (STT) with oral diazepam reduced length of stay (LOS) and cumulative benzodiazepine dose by comparison with standard fixed-dose regimen. In this study, we aim to describe the feasibility of STT in an emergency department (ED) short-stay clinical decision unit (CDU) setting.MethodsIn this retrospective cohort study, we describe our experience with STT over a full calendar year (2014) in the CDU. A retrospective chart review was conducted and data collection included demographics, clinical details, total cumulative dose of diazepam, receipt of parenteral thiamine, LOS and disposition.Results5% (n=174) of 3222 admissions to CDU required STT. Collapse or seizure (41%, n=71) and alcohol withdrawal (21%, n=37) were the most common reasons recorded for admission to CDU in those who required STT. Median Alcohol Use Disorders Identification Test score was 25 and 112 patients (64%) had at least one Clinical Institute Withdrawal Assessment for Alcohol revised measurement ≥10, triggering a dose of diazepam (20 mg). The median cumulative oral diazepam dose was 20 mg while 24 (15%) patients received a cumulative dose of 100 mg or more. Median time for STT was 12 hours (IQR=12, R=1–48). 3% (n=5) of patients required further general hospital admission and median LOS in CDU, was 22 hours (IQR=20, R=1–168).ConclusionSTT is potentially feasible as a rapid and effective approach to managing alcohol withdrawal syndrome in the ED/CDU short-stay inpatient setting where patient LOS is generally less than 24 hours.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a newly described form of encephalitis associated with prominent psychiatric symptoms at onset. Recognition of the symptom complex is the key to diagnosis. Most patients with anti-NMDAR encephalitis develop a multistage illness that progresses from initial psychiatric symptoms to memory disturbance, seizures, dyskinesia, and catatonia. Psychiatric manifestations include anxiety, mania, social withdrawal, and psychosis (i.e., delusions, hallucinations, disorganized behavior). The disorder is more common in females (80%), in approximately half of whom it is associated with an underlying ovarian teratoma. Treatment involves immunosuppression, with steroids and intravenous immunoglobulin considered first line. The disorder is particularly relevant to psychiatrists, because most patients are initially seen by psychiatric services. Psychiatrists should consider anti-NMDAR encephalitis in patients presenting with psychosis as well as dyskinesia, seizures, and/or catatonia, especially if there is no history of a psychiatric disorder. We present the case of a 37-year-old woman who demonstrated many of the key clinical features of this potentially treatable disorder.

Objectives Brief screening tools may help clinicians in busy settings detect patients who are experiencing severe psychological distress. This study examined the performance of the Distress Thermometer (DT) and a two-item depression screen [the Patient Health Questionnaire-2 (PHQ-2)] with a ‘help’ question in screening for distress and psychiatric morbidity among patients with advanced cancer. Methods Two hundred and five patients with advanced cancer completed the DT, the PHQ-2 and ‘help’ question and the Hospital Anxiety and Depression Scale and were interviewed using the Structured Clinical Interview for DSM-IV (SCID). The performance of the screening tools was examined against the Hospital Anxiety and Depression Scale and the SCID. Results Overall, discrimination levels were comparable for the DT [area under the curve (AUC) 0.80–0.81] and the PHQ-2 (AUC 0.73–0.85). The DT performed best in detecting cases of distress and mood, anxiety or adjustment disorders (sensitivity 100%), but it had poor specificity (49–60%). The best performance in terms of combined sensitivity and specificity was the PHQ depression item versus the SCID (sensitivity 88%, specificity 73%). The inclusion of the ‘help’ question with the PHQ-2 resulted in high levels of specificity (≥89%), but there was a significant drop in sensitivity (≤54%). Conclusion Ultra-brief screening tools offer an efficient means of identifying patients with advanced cancer with severe distress or psychiatric morbidity but are less effective at identifying non-distressed individuals. Used in conjunction with a ‘help’ question, these tools can help clinicians identify patients who are both distressed and likely to accept professional support.

Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder referred to gastroenterologists. Although the pathophysiology remains unclear, accumulating evidence points to the presence of low-level immune activation both in the gut and systemically. Circulating polyunsaturated fatty acids (PUFA) have recently attracted attention as being altered in a variety of disease states. Arachidonic acid (AA), in particular, has been implicated in the development of a pro-inflammatory profile in a number of immune-related disorders. AA is the precursor of a number of important immunomodulatory eicosanoids, including prostaglandin E(2) (PGE(2)) and leukotriene B(4) (LTB(4)). We investigated the hypothesis that elevated plasma AA concentrations in plasma contribute to the proposed pro-inflammatory profile in IBS. Plasma AA and related PUFA were quantified by gas chromatography analysis in IBS patients and controls. Both PGE(2) and LTB(4) were measured in serum using commercially available ELISA assays. AA concentrations were elevated in our patient cohort compared with healthy controls. Moreover, we demonstrated that this disturbance in plasma AA concentrations leads to downstream elevations in eicosanoids. Together, our data identifies a novel proinflammatory mechanism in irritable bowel syndrome and also suggests that elevated arachidonic acid levels in plasma may serve as putative biological markers in this condition.

Objective The goal of this article was to describe the clinical characteristics and outcomes of patients diagnosed with psychogenic nonepileptic seizures (PNES). Methods We conducted a retrospective review of patients diagnosed with PNES in a 5-year period. Results Fifty patients with PNES were identified, giving an estimated incidence of 0.91/100,000 per annum. Thirty-eight were included for review, 15 of whom were male (39%). Eighteen patients had been diagnosed with epilepsy as well as PNES (47%). We demonstrated a gender difference in our patients, with males having higher seizure frequencies, more antiepileptic drug use, and a longer interval before diagnosis of PNES. Females were diagnosed with other conversion disorders more often than males. Impaired social function was observed in PNES, as was resistance to psychological interventions with a subsequent poor response to treatments. Conclusions PNES remains a difficult condition to treat, and may affect males in proportions higher than those described in previous studies.

Stroke has a major impact on physical and cognitive ability, and quality of life. This study aims to examine the effect of multidisciplinary rehabilitation on outcome in an Irish young stroke population.Fifty consecutive patients younger than 65 were prospectively recruited to this observational study. Physical and cognitive ability, and quality of life were measured on admission and discharge.All patients were transferred to the rehabilitation unit from the acute hospital where they had received their initial management. Median length of time from stroke onset to transfer was 112 days. After a median of 70 days, 43 patients were discharged home. Patients made significant gains in physical (Barthel index 12 to 18) and cognitive ability (mini-mental state examination 22 to 25). Quality of life improved in all eight domains of the 36-items Short Form with four domains returning to level seen in the general population.This study documents the improvements in physical and cognitive abilities, and quality of life in a sample of patients in rehabilitation. A comprehensive rehabilitation programme that includes acute and late multidisciplinary phases can improve the outcome of patients following stroke.

Depression is a significant risk factor for and consequence of both cardiovascular disease and stroke. The pathophysiological processes underlying this association are poorly understood. This study utilised a technique for measurement of whole blood platelet surface glycoproteins involved in early adhesion and aggregation in sample populations of patients with depression and stroke, and healthy controls. We analysed the platelet surface glycoproteins GPIb and GPIIbIIIa using flow cytometry in eight depressed subjects (Hamilton depression score >17), 14 post-stroke subjects (seven depressed and seven non-depressed), and in eight healthy control subjects. The number of GPIb receptors was significantly increased in subjects with depression and in post-stroke subjects compared to control subjects. The number of GPIb receptors from post-stroke subjects was not significantly different from that of depressed subjects. There were no differences between any groups in measures of GPIIbIIIa receptor numbers. No additive effect of co-morbid depression on the surface expression level of either marker could be detected in the post-stroke subjects. Platelet dysfunction may be involved in the pathophysiological process underlying the association between depression and cerebrovascular disease.

Serotonin has long been implicated as a key neurotransmitter in migraine. There is a dearth of research specifically examining 5-HT1A receptor sensitivity in migraine despite the importance of this receptor in regulating central serotonergic tone. In this study we examined the hypothesis that migraine without aura is associated with hypersensitivity of central 5-HT1A receptors, using a 5-HT1A neuroendocrine challenge drug and comparing serum prolactin responses between a test group with migraine and a matched group of healthy controls. Twelve female subjects fulfilling International Headache Society (IHS) criteria for migraine without aura were evaluated. Following an overnight fast, subjects presented for testing at 9am. An intravenous canula was inserted and serum prolactin was assessed at baseline and every 30 min for 3 h following a single dose of 30 mg oral buspirone, a 5-HT1A-receptor agonist. Subjects were assessed during the first 5 days of the menstrual cycle. No subjects were taking psychotropic medication or migraine prophylactic treatment. Patients with current or previous psychiatric disorder, daily headache or analgesic overuse were excluded. 16 healthy female volunteers matched for age and menstrual status were also evaluated and served as controls. There was no difference in baseline prolactin between groups. There was a significant rise in prolactin following buspirone in both groups. Subjects with migraine had a significantly increased prolactin response to buspirone (delta max) compared to controls ( P < 0.001). This study supports the hypothesis that migraine without aura is associated with a relative hypersensitivity of central 5-HT1A receptors. This is of relevance given the role of the 5-HT1A receptor in controlling raphe 5-HT tone and in the possible association between migraine and anxiety and depression.

The aim of the study was to compare symptom-triggered and standard benzodiazepine regimens for the treatment of alcohol withdrawal syndrome in an emergency department clinical decision unit. The authors found that the symptom-triggered approach reduced cumulative benzodiazepine dose and length of stay.

Objective This study examined the psychiatric and neuropsychological profiles of people with psychogenic nonepileptic seizures (PNES). Methods Twenty-people who had been diagnosed with psychogenic nonepileptic seizures (PNES), but not epilepsy, were recruited into this study. A healthy control group was also recruited and was matched for age and gender. All participants underwent structured psychiatric assessment and psychometric assessment. Neuropsychological assessment was carried out using the Cambridge Neuropsychological Test Battery (CANTAB) after participants passed the Medical Symptom Validity Test (MSVT) of effort. Results One patient failed the MSVT and was excluded from the analysis. Therefore, data from 19 people with PNES and their matched healthy controls were analyzed. Compared with controls, people with PNES had significantly higher levels of depressive symptoms, anxiety symptoms, dissociative experiences, and alexithymic traits. In addition, people with PNES had impairments in spatial working memory and attention when compared with healthy controls. Conclusion To our knowledge, this is the first study to report that, compared with controls, people with PNES have abnormal cognitive functioning after controlling for effects of effort and FSIQ. People with PNES also have high levels of anxiety, depressive, and dissociative symptoms. In addition, they appear to particularly focus on health problems and show evidence of chronic emotional dysregulation. Further studies are required to replicate our results and to help clarify the pathogenic mechanisms underlying PNES.

Background The EEG is a commonly requested test on patients attending psychiatric services, predominantly to investigate for a possible organic brain syndrome causing behavioural changes. Aims To assess referrals for EEG from psychiatric services in comparison with those from other sources. We determine which clinical factors were associated with an abnormal EEG in patients referred from psychiatric sources. Methods A retrospective review of EEG requests in a 1-year period was performed. Analysis of referral reasons for psychiatric patients was undertaken, and outcome of patients referred from psychiatric services post-EEG was reviewed. Results One thousand four hundred and seventy EEGs were reviewed, of which 91 (6.2%) were referred from psychiatry. Neurology service referrals had detection rates of abnormal EEGs of 27%, with psychiatric referrals having the lowest abnormality detection rate of 17.6% (p

(1). To examine the prevalence of depressive symptoms and operationally defined depressive disorder (major depression) in an Irish sample of subjects undergoing inpatient rehabilitation following their first stroke. (2). To investigate factors predictive of depression following stroke. (3). To examine the relationship between post-stroke depression and outcome following inpatient rehabilitation.Fifty consecutive patients meeting inclusion criteria who were admitted for inpatient rehabilitation to a specialised unit following their first stroke were prospectively studied.first stroke 3 - 12 months previously, lesion identified on CT or MRI, age 18 - 65 years, at least some sensory/motor impairment, no pre-existing disabling condition and Barthel Index score14 prior to stroke. Mood (Center for Epidemiologic Studies Depression scale, Hamilton Depression Rating Scale, DSM-IV diagnostic criteria for Major Depressive Disorder), Cognition (Mini-Mental State Examination) and Disability (Barthel Index, Rankin Disability Scale) were assessed one week after admission (baseline) and again after 2 months of rehabilitation. Outcome was measured as effectiveness of rehabilitation (Shah et al., 1990) and length of inpatient stay (LOS).10/50 (20%) of the sample met criteria for major depressive disorder on admission. The best predictor of depression was gender, with females having a two-fold higher rate of both subjectively reported and objectively rated depressive symptoms. Depression was unrelated to baseline Barthel Disability, side of lesion or previous psychiatric history. The best predictor of effectiveness of rehabilitation was baseline Barthel Disability score. Depression did not predict either effectiveness or LOS.(1). Major depression is common in subjects undergoing rehabilitation following their first stroke. (2). Females appear to be especially at risk, possibly reflecting an increased general risk of depression. (3). Depression in our sample was not related to functional disability following stroke or early functional outcome following rehabilitation.

Objective.—To examine factors associated with social, occupational, and psychological burden of common primary headache (migraine and tension-type headache). Background.—The personal and social burden of primary headache is high. Health, occupational, social, and psychological factors contributing to burden in people with disabling headache have not been fully unravelled. Methods.—One hundred eighty consecutive patients with either migraine or tension-type headache attending a specialty headache outpatient clinic for the first time were evaluated over a 9-month period. Headache subtype was operationally defined according to International Headache Society criteria. Headache frequency, duration, and severity were recorded. Occupational and social disability were quantified using the Migraine Disability Assessment questionnaire. Psychological burden was quantified using the 28-item General Health Questionnaire, the Beck Depression Inventory, and the State-Trait Anxiety Inventory. Premorbid vulnerability to life stress was quantified using the neuroticism subscale of the Eysenck Personality Inventory. Results.—Patients with frequent (chronic) headache scored higher on the Migraine Disability Assessment questionnaire and had higher Beck Depression Inventory and General Health Questionnaire depression scores than those with less frequent (episodic) headache. Frequency of headache, but not pain severity, duration, or diagnosis, predicted both Migraine Disability Assessment total disability and General Health Questionnaire/Beck Depression Inventory depression. Neuroticism was predictive of depression but not disability. Patients with chronic migraine had the highest depression and disability scores. Conclusion.—The number of days per month with headache is a key determinant of headache-related burden in those attending specialty clinics. Frequent (chronic) headache is associated with significantly higher psychopathology scores and general social impairment, but the direction of this relationship is not clear. Those with migraine and chronicity are the most impaired.

Despite the importance of the 5HT1A receptor in regulating central serotonergic tone, there is a dearth of research examining its role in migraine. In this study, we examined the hypothesis that there would be altered neuroendocrine responses to a 5HT1A agonist challenge in different migraine subtypes. Prolactin (PRL) responses to the 5HT1A receptor agonist drug buspirone were compared in 30 female subjects with migraine (ten migraine with aura, MA; ten migraine without aura, MO and ten chronic/transformed migraine, CM), and ten healthy controls matched for age, gender and menstrual status. None of the subjects were taking psychotropic medication or migraine prophylactic treatment and those with formal psychiatric disorder were excluded. Endocrine responses were determined by measuring differences between baseline PRL and maximum increases post-buspirone (deltaPRL). There was no difference in baseline PRL between groups. MA subjects did not differ in their PRL responses to buspirone compared to healthy controls. The MO group had a four-fold increase in mean deltaPRL responses compared to healthy controls. Mean deltaPRL was also increased in the CM group compared to controls, but the difference was less exaggerated. This study indicates that there is supersensitive central amine receptor function in MO and CM, but not in MA. These findings support the hypothesis that central 5HT function differs among the migraine subtypes. The results also suggest that migrainous 'transformation' may be associated with adaptive changes in central 5HT receptor sensitivity. The relative contribution of 'state' and 'trait' receptor function to these findings as well as the possible role of dopamine receptors is discussed.

Major depression is associated with both hypothalamic-pituitary-adrenal (HPA) axis overactivity and immune system activation. Depression is a common occurrence following interferon (IFN)-a treatment. While IFN-alpha is known to stimulate the HPA axis, little is known about the effects of exogenous IFN-a in humans on the proinflammatory cytokine interleukin (IL)-6, a marker of immune system activation. This study examined the acute effects of IFN-alpha on cortisol and IL-6 release, and the time course of any changes in these variables. Serum cortisol and plasma IL-6 were assessed in healthy volunteers over an 8-h period following 3 million units subcutaneous IFN-alpha or placebo using a double-blind, placebo-controlled crossover design. IFN-alpha resulted in a significant increase in both cortisol and IL-6. Regular sampling over 8 h did not delineate any sequential effect of the rise in these variables over time. We conclude that IFN-alpha acutely stimulates both the HPA axis and proinflammatory cytokine release. The hypothesis that the effect of IFN-alpha on the HPA axis is indirect and mediated by IL-6 was not supported by this study. Our findings are nonetheless of relevance to the aetiology of depression following IFN-alpha.

We present the case of a 31-year-old woman with recent refractory bipolar disorder who developed a malignant syndrome preceded by catatonic motor features. This resistant case of lethal catatonia responded selectively to high-dose olanzapine treatment. The case illustrates the need to consider lethal catatonia in apparent cases of neuroleptic malignant syndrome that do not respond to conventional treatment with dantrolene and bromocriptine.

SummaryBoth poor insight and depressive symptomatology are common features of schizophrenia that may be independent of positive and negative symptoms. Forty-six patients with DSM-III-R schizophrenia were evaluated for level of insight (schedule for unawareness of mental disorder), depression (Calgary depression scale for schizophrenia, Beck depression inventory), and self-deception or denial (balanced inventory of desirable responding). Patients with a greater unawareness of their illness had relatively less depressive symptomatology and relatively greater self-deception. This relationship was particularly strong for unawareness of the social consequences of having a mental disorder. These results suggest that the presence of depressive symptomatology in schizophrenia is related to the level of insight, and contingent at least in part on the absence of self-deception as a denial defense.
