Objectives: To describe existing Scottish psychiatric emergency services, particularly the staffing levels and supervision of junior staff, to assess the level of recording of the urgency of referrals to such services and to determine the approximate rates of emergency presentations. Method: A postal questionnaire was sent to all 29 Scottish psychiatric hospitals, addressed to the physician superintendent or the consultant in charge of emergency services. Twenty-six were returned and further details on these and the other three services were clarified by telephone contact with medical records and medical staff. Description of services, number of presentations, staffing levels and degree of supervision were recorded. Rates of referral were estimated for Health Board populations. Results: Services varied from hospital based walk-in clinics through to community orientated domicillary assessment services. Emergency presentations are usually seen by junior staff in a psychiatric hospital outpatient department, a psychiatric ward or at an accident and emergency department. Out of hours supervision is typically by telephone advice from a consultant. Rates of emergency presentations based on collected and estimated figures were highest in urban areas. Conclusions: Scottish psychiatric emergency services are disparate in nature but all provide a 24 hour service. There is a lack of reliably collected data on the urgency of referrals but estimates suggest that there is a greater need for emergency psychiatric care in the large urban areas. Working definitions are proposed to assist in the classification of the urgency of referrals.

A 54 year old woman presenting to the psychiatric services with persecutory delusions, complex visual hallucinations and fluctuating levels of consciousness was discovered to have a meningioma occupying the cerebellopontine angle. The psychiatric symptomatology of cerebellopontine angle lesions is reviewed and the pathogenic mechanisms are explored in the light of the symptomatology observed.

Objective: To quantify the perceived discrepancies between the medication that GPs believed their patients were taking and that which was recorded on admission to acute psychiatric wards.

Methods: A prospective survey of 107 consecutive admissions to a Swansea psychiatric hospital was carried out.

Results: In 62% of patients studied, there was at least one discrepancy each and in 33%, the discrepancies were considered potentially clinically significant.

Conclusions: The study showed a significant number of potentially serious discrepancies in medication at the GP-Hospital interface and highlighted the need for improved communication between GPs and their psychiatric colleagues. The possible reasons for the discrepancies and the implications for communication between primary and secondary care for psychiatric patients are explored.

Objective: The authors were aware of a high level of aggression in their centre and felt that a systematic review of incidents of aggression could be of benefit to both staff and residents. Method: A retrospective review of all incidents over a one year period was performed. Data involving the resident and the incident itself were analysed. An ICD 9 psychiatric diagnosis was attributed to each resident where possible. Results: The results show a large number of incidents, mostly of a minor nature. In almost half the incidents the nurse was the victim. There was a lower number of incidents in January and February. Forty one of the 45 residents involved in incidents had a psychiatric diagnosis. Conclusion: There is a general trend for moving from residential settings to the community. Our results suggest that as time goes on our centre will contain more residents with a psychiatric diagnosis who have a potential for aggression. We suggest ways of coping with this aggression and produce an incident form for recording aggressive incidents.

With advancements in medical science over past decades, our aging population has increased substantially. Census studies in 2001 showed that 429,100 of the population of the Republic of Ireland were aged 65yrs and older, making up 11.2% of the overall population. While the overall population of the Republic is expected to remain stable over the next ten years, the demographic projections for the elderly population is for significant growth: numbers of over 65yrs are expected to increase by nearly 108,000 people between 1996 - 2011, comprising over 14.1% of the overall population. In particular, our communities will contain a much higher proportion of octogenarians and nonagenarians: at present 21% of our over 65's are 80 yrs or older; by 2011, it is projected that this number will increase to 25%. In tandem, the prevalence of dementia will increase.

In 2000, it was estimated that 31,000 people suffered with dementia in the Republic of Ireland, and this figure is expected to increase by 5000 cases per year between 2001-2011. The ultimate outcome of this demographic shift, will be higher demands on medical services for older people, especially geriatric medicine and old age psychiatry. This paper will focus on two particular aspects of management which will increasingly impact on the work of old age psychiatrists – medicolegal issues and management issues in dementia.

Three cases of schizophrenia (DSM-III-R) (l), whilst responding to treatment, exhibit a group of symptoms which had the essential features of “flashbacks”, as described in relation to psychedelic drugs, though there was no evidence of psychedelic drug misuse. Symptoms were characterised by memory flashes of the original psychotic experience, followed immediately by very brief re-experiencing of earlier symptoms, including visual perceptual changes in clear consciousness and full insight. Symptoms were less clear, less severe, but more distressing, than the original episodes. Symptoms were triggered by stress/anxiety, and relieved by an anxiolytic. The association of flashbacks with schizophrenia is discussed.

A case of chronic disulfiram (Antabuse) toxicity is described, in the context of a literature review, apparently the first such description from Ireland. The rare combination of encephalopathy with peripheral neuropathy occurred in this case, along with other probably related features. These included a fluctuating clinical course, cerebellar ataxia, grand mal seizures, impotence and a delay in improvement on discontinuing disulfiram. It is likely that symptoms of anxiety and depression in this man were also in part induced by disulfiram toxicity, but interpretation of events is complicated by developing arteriosclerosis. The difficulties in distinguishing toxic effects of disulfiram from complications of chronic alcoholism are emphasized, with resulting delay in recognizing disulfiram toxicity.

We describe an unusual cause of autobiographical memory loss in a 55 year old man who presented with prominent memory loss for significant events in his life over a period of five years with evidence of patchy memory loss for events prior to this. It was associated with emotional lability and was complicated by a number of tragic events in his life in the previous four years. In addition there were a number of brief episodes (< 30 mins) where he would transiently lose his memory for events including for hours, days or months prior to the event. Neuropsychological assessment confirmed prominent autobiographical memory loss with minimal deficits in other domains. An electroencephalogram (EEG) revealed a simple partial seizure arising from the right temporal lobe, pointing to a diagnosis of Transient Epileptic Amnesia. He was commenced on anti-epileptic medication and responded both subjectively and objectively. There are approximately 94 cases of TEA described in the literature and the diagnostic criteria and postulated aetiology of this illness is discussed here. Clinicians need to have high index of suspicion of epilepsy when assessing a patient with prominent autobiographical memory impairments.

Objectives: To describe the psychosocial and clinical characteristics of children referred to a community-based child and adolescent mental health service, whose mothers reported that they took opiates during the pregnancy.

Methods: In a retrospective study, the case notes of all children whose mothers reported that they had been exposed to opiates in utero, and who were referred to the Department of Child and Family Psychiatry, Mater Hospital, between 2001–2003, were identified by maternal reports. Information was obtained on age, gender, referral source, socio-economic group, family type, number of siblings, involvement of community care services, nature of presenting problems, diagnosis, interventions offered, and treatment difficulties. Information was recorded anonymously.

Results: 15 children were identified, of whom nine were male. Most were found to be living with their mother alone or with their mother and a partner, and to be socially and financially disadvantaged. Their presenting complaints usually involved combinations of aggressive, hyperactive, and oppositional behaviour. Diagnoses included ADHD, a speech and language disorder, and an axis II disorder. Interventions were frequently unsuccessful because of parents' difficulties with attending appointments, and because of instability in the families' living arrangements.

Conclusions: These children, due to a complex interplay of biological and psychosocial adversity, are at serious risk of ongoing psychiatric disorders in childhood and adolescence, and for adverse outcomes in adult life. A prospective cohort study of all children born to opiatedependent mothers is necessary to quantify the level of risk and identify resilience factors.

What is probably one of the most exciting potential advances in psychiatry is occurring slowly, possibly too slowly and has gone unnoticed by many. I am talking about ‘Chaos theory’, which is a mathematical concept that has influenced the study of such diverse subjects as the weather, evolution and the electroencephalogram. Is it our lack of mathematical training that makes us so fearful? This may be so, but we can still understand chaos theory without having to learn large mathematical formulae.

Chaos theory is about dynamic non-linear systems that are orderly at first, but may become completely disorganised over time. That is initial conditions that are alike in the beginning, may have markedly different outcomes over time. An analogy commonly drawn from weather studies is the butterfly effect. This draws on the premise of initial conditions which is a butterfly fluttering its wings in Tokyo can lead over time and distance to a storm for example over New York. In other words a small perturbation in a non-linear system can lead to great variations in outcome. The chaos theory is about how phenomena can vary between different kinds of states around what is called a ‘strange attractor’ and obtain from this a semblance of order out of what initially can be perceived as disorder.

In this way chaos differs from random behaviour and causal systems. Eventual outcome in a random system is not determined by initial conditions. The eventual outcome in a causal system has a linear relationship with its initial conditions. In other words a small change in initial conditions will lead to a small change in the eventual outcome. But in Chaos theory a small change in the initial conditions can lead to major changes in the eventual outcome. These changes become exponential over time.

The original example of a chaotic system was developed by Lorenz. In his early work on weather systems he found using computer simulations that started with similar, but slightly different initial data, orbits would stay close to each other for a while but would eventually diverged in a manner that turned out to be exponential over time. His model was deterministic, that is the orbits were unique in the sense that there was only one orbit passing through a given point of the space in which the orbit lay. The three variables he was measuring were convective air circulation in relation to vertical and horizontal temperature variations.

This article outlines the development of the role of the Health Service Executive Authorised Officer in Ireland, the professional applicant for the involuntary admission of an adult to hospital beyond that which was envisioned in the Mental Health Act 2001.

We present the case of a 68-year-old lady with a background diagnosis of bipolar disorder, who developed significant episodes of intractable delirium during each of her last three inpatient psychiatric admissions, where she was admitted with mania and psychosis. The case demonstrates diagnostic and management difficulties secondary to this delirium. We discuss the probable cause of this delirium and the various management strategies utilised in an effort to ameliorate her condition.
