Follow up of patients presenting with fatigue to an infectious diseases clinic.

OBJECTIVES: To determine the symptomatic and functional status during follow up of patients referred to hospital with unexplained fatigue and to identify patient variables associated with persistent functional impairment. DESIGN: Follow up by postal questionnaire six weeks to four years (median 1 year) after initial clinical assessment of patients referred to hospital during 1984-8. SETTING: Infectious diseases outpatient clinic in a teaching hospital. PATIENTS: 200 consecutive patients with fatigue of uncertain cause for at least six weeks; 177 fulfilled the inclusion criteria. MAIN OUTCOME MEASURES: Findings at initial assessment; current symptoms, beliefs about the cause of illness, coping behaviours emotional disorder, social variables including membership of self help organizations, and degrees of recovery and functional impairment from questionnaire responses. RESULTS: 144 (81%) patients returned completed questionnaires. Initial assessment did not indicate the cause of fatigue, other than preceding infection. The proportion of patients with functional impairment was significantly smaller with longer follow up (33% (11/33) at two to four years, 73% (29/40) at six weeks to six months; chi 2 for trend = 12.5, df = 1; p less than 0.05). Functional impairment was significantly associated with belief in a viral cause of the illness (odds ratio = 3.9; 95% confidence interval 1.5 to 9.9), limiting exercise (3.2; 1.5 to 6.6), avoiding alcohol (4.5; 1.8 to 11.3), changing or leaving employment (3.1; 1.4 to 6.9), belonging to a self help organization (7.8; 2.5 to 23.9), and current emotional disorder (4.4; 2.0 to 9.3). CONCLUSIONS: Short term prognosis for recovery of function was poor but improved with time. Most patients had made a functional recovery by two years after initial clinic attendance. Impaired functioning was more likely with certain patient characteristics. Prospective studies are required to clarify whether these associations are the consequences of a more disabling illness or indicate factors contributing to impaired function.

Trends in deliberate self poisoning and self injury in Oxford, 1976-90.

OBJECTIVE: To review trends in deliberate self poisoning and self injury (attempted suicide) over 15 years (1976-90) on the basis of general hospital referrals. DESIGN: Prospective data collection by computerised monitoring system. SETTING: Teaching general hospital. SUBJECTS: All patients aged 15 and over (n = 9605) referred to the hospital after episodes (n = 13,340) of deliberate self poisoning or self injury. MAIN OUTCOME MEASURES: Rates based on population of Oxford city; changes in substances used for self poisoning; history and repetition of attempts; and rates of admission to the hospital and of referral to the psychiatric service. RESULTS: Attempted suicide rates for women declined during the late 1970s and early 1980s but increased again during the late 1980s. Those for men remained relatively steady throughout the period. Highest mean annual rates occurred in women aged 15-19 (711/100,000) and in 20-34 year old men (334/100,000). The proportion of overdoses with paracetamol increased from 14.3% (125/873) in 1976 to 42% (365/869) in 1990 (chi 2 for trend = 481, p less than 0.01). Throughout the period the proportions of referred patients admitted to hospital and of those attempting suicide for the first time (over two thirds) did not decrease. Annual rates of repetition of attempts by women declined from 15.1% (257/1700) in 1976-8 to 11.9% (161/1356) in 1987-9 (chi 2 for trend = 7.8, p less than 0.01). Lower repetition rates occurred in women admitted to hospital and referred to the psychiatric service (431/4585, 9.4%) than in those not referred (42/235, 17.9%; chi 2 = 17.2, p less than 0.0001). CONCLUSIONS: Rates of attempted suicide declined in the 1970s and early 1980s, in women, but there are probably at least 100,000 hospital referrals a year in England and Wales because of this problem. Prevention of paracetamol self poisoning requires urgent attention, and psychosocial assessment should be conducted with as many of those who attempt suicide as possible.

Sex therapy for erectile dysfunction: characteristics of couples, treatment outcome, and prognostic factors.

Outcome and prognostic factors were studied in 36 couples who entered sex therapy because of the male partners' erectile dysfunction. Treatment was completed by two thirds. Noncompletion was associated with lower socioeconomic status, the female partner having a history of psychiatric treatment, pretreatment poorer motivation of the male partner, poor communication in the general relationship, and less sexual pleasure experienced by the female. A positive treatment outcome occurred in 69.4%, and was associated with better pretreatment communication and general sexual adjustment, especially the female partner's interest and enjoyment of sex, absence of a positive psychiatric history in the female partner, and a couple's early engagement in homework assignments. Results highlight important aspects of the initial assessment, indicate couples for whom the initial phase of treatment should be prolonged and modified or an alternative approach considered, and have implications for assignment of couples to treatment groups in evaluative studies of therapy.

Deliberate self-poisoning and self-injury in adolescents. A study of characteristics and trends in Oxford, 1976-89.

In Oxford during the late 1970s and early 1980s a decline in rates of deliberate self-poisoning and self-injury in older female teenagers was followed by a steady increase between 1986 and 1989. Rates for male adolescents and young female adolescents remained relatively stable throughout 1976-89. Applying the Oxford rates to England and Wales suggest a total of 18,000-19,000 hospital-referred cases per year. While self-poisoning with minor tranquillisers and sedatives has declined, there has been a marked increase in paracetamol self-poisoning, such that by 1988-89 it was involved in 48.3% of overdoses. Relationship difficulties were the most frequent problems faced by these adolescents, especially the females, with unemployment and alcohol and drug problems also being common, especially in males, but psychiatric disorders relatively rare. Substantial proportions of the adolescents, especially the males, were not living with either relatives or friends, and had a history of violence or a criminal record. The annual rate of repetition of attempts, which was 8.9% overall, was higher in adolescents not admitted to the general hospital, and in females not referred to the hospital psychiatric service. Adolescent attempted suicide clearly continues to be a major health problem for which both effective preventive and therapeutic strategies are badly needed.

Low sexual desire: sex therapy results and prognostic factors.

In a prospective study of 60 couples who entered sex therapy because of the female partners' low sexual desire, 38 (63.3%) completed treatment and 34 (56.7%) had a positive outcome. The principal predictor of completion of treatment was the male partners' apparent motivation at the outset. Poorer outcome was associated with younger age of the couple (especially the male partner) and a shorter duration of the sexual problem. Surprisingly, few aspects of the couples' general relationships prior to treatment were related to outcome, except for poorer outcome being associated with a history of previous separations. The apparent lack of significant contribution of general relationship factors and psychopathology to outcome probably reflects the stringency of the initial selection process. Eventual outcome was also related to couples' progress by the third treatment session. The modest outcome of treatment for low sexual desire in this and other studies emphasises the need for further understanding of factors which contribute to this problem and for the development of novel treatment strategies.

Mood disorders in the year after first stroke.

An unselected community sample of 128 patients were studied over the 12 months after their first stroke, and compared with a control sample of subjects from the general population. Psychiatric status was assessed using the PSE and BDI. Symptoms of mood disorder were commoner in the stroke patients than the controls, but the differences were not substantial and had largely disappeared by 12 months. Psychiatric problems encountered included agoraphobia, social withdrawal, apathy and self-neglect, irritability and pathological emotionalism. While there was a high cumulative incidence of psychiatric disorder, little of it persisted: only two cases of major depression were present for the whole 12 months. We believe undue emphasis has been placed in the recent literature on major depression as a specific syndrome following stroke.

Psychiatric problems among medical admissions.

The prevalence, nature, associations and outcome of psychiatric morbidity among four hundred and fifty severe general medical admissions are described. Affective disorder was diagnosed in 13 percent of men and 17 percent of women. It was associated with a history of previous psychiatric disorder and current social problems. Persistent affective disorder after discharge was associated with continuing medical and social problems. Alcohol problems were common in men, especially in those with social problems, and often went unrecognized by medical staff. Cognitive impairment was confined to the elderly and was associated with longer hospital stay and high mortality. Patients with emotional and cognitive disorder make considerable demands on medical, social and psychiatric services during and following admission. The implications for improved recognition and management of psychiatric morbidity in general medical patients are discussed.

Significance of psychiatric symptoms in general medical patients with mood disorders.

Little difference was found between the psychiatric symptoms of medical patients and general-population subjects with affective disorder, both groups having been assessed with the same procedure (Present State Examination). Discrimination between medical patients with and without affective disorder was best achieved when patients with depressive and anxiety disorders were considered separately. Depressed mood, morning depression, and hopelessness were the key symptoms in the depressives, and nervous tension, free-floating anxiety, panic attacks, and specific phobias in the patients with anxiety disorders. Symptom profile did not distinguish patients with persistent affective disorders from those whose disorders had resolved at a 4-month follow-up.

The relationship between intellectual impairment and mood disorder in the first year after stroke.

In a community-based study of patients with a first-ever stroke, intellectual impairment (as defined by scores on a common screening test for dementia, the Mini-Mental State Examination) was found in 26% at 1 month post-stroke, and in 21% at 6 and 12 month follow-up. Low scores on the screening test were associated with greater age, physical disability before the stroke, larger stroke lesion volumes as measured on CT scan, and non-stroke changes such as atrophy and white matter low attenuation on the CT scan. There was a negative correlation between scores on the Mini-Mental State Examination and symptom levels on two measures of mood disorder. However, there was no evidence of a specific relationship between major depression and low scores on the Mini-Mental State. We examined various aspects of the relationship between mood symptoms and low scores on the Mini-Mental State, but found no evidence to support the suggestion that this relationship represented an example of depressive pseudodementia. We discuss the significance of our findings for clinical psychiatry and neuropsychology.

Mood disorders in long-term survivors of stroke: associations with brain lesion location and volume.

Sixty surviving patients from a community-based stroke register who had CT scan evidence of a single brain lesion and neurological signs appropriate to it were interviewed three to five years following their first-ever stroke. Mood disorder (anxiety and depression), physical disability, and intellectual impairment were assessed using standardized measures. The position and volume of the brain lesion was determined from CT scans performed soon after the stroke. The prevalence of depressive disorder was lower in this sample than that reported in previous studies (DSM-IIIR major depression 8.3%; all DSM-IIIR depressive disorders 18.3%). Reports by other workers for an association of depressive disorder either with left-sided brain lesions, or with anteriorly placed lesions in the left cerebral hemisphere, were not supported. Neither was there evidence of a correlation between symptom score and proximity of the lesion to the anterior pole of the left cerebral hemisphere. Psychiatric symptom scores were however greater with larger volume brain lesions. Anxiety disorders, especially agoraphobia, were relatively common (20% if diagnosed in the presence of depressive disorder), but were not related to lesion location or volume.

Mood disorders after stroke and their relation to lesion location. A CT scan study.

In a community-based study of stroke survivors, we identified 73 consecutive patients with a stroke, the first ever in a lifetime, who had a CT scan which showed a neurologically appropriate single stroke lesion, and who did not have a psychiatric disorder in the year preceding the stroke. A detailed follow-up study of these patients using standardized psychiatric assessments failed to confirm a number of recent claims about poststroke depressive disorders. We found no evidence that left-sided lesions were associated with more severe or persistent depressive symptoms, or that right-sided lesions were associated with hypomania. The DSM III syndrome of major depression was much less common than has previously been reported, and was not specifically associated with lesions placed anteriorly in the left hemisphere. There was a weak correlation between mood symptom scores and the proximity of the stroke lesion to the frontal pole of the hemisphere, but no evidence of a difference between right and left hemisphere strokes in the nature of the relationship between lesion distribution and mood symptoms. We suggest that previous studies have different findings because of differences in the conventions applied to the definition and measurement of psychiatric disorders after stroke, and because other studies have concentrated on selected inpatient populations.

Reliability of routine hospital data on poisoning as measures of deliberate self poisoning in adolescents.

STUDY OBJECTIVE: The aim was to assess the extent to which routinely collected data on poisoning in adolescents reflected deliberate self poisoning and, in doing, so to assess the accuracy of the diagnostic information on poisoning in the routine hospital abstracts which form the joint data base of Hospital Activity Analysis and the Oxford Record Linkage Study (ORLS). DESIGN: A comparison was made (a) of all eligible ORLS records during the study period with an independent source of records; and (b) of a random sample of records from an independent source with ORLS. SETTING: Records of patients admitted to the John Radcliffe Hospital in Oxford were used. SUBJECTS: These were (a) patients aged 10-20 years between 1980 and 1985 with a diagnosis of poisoning by drugs and medicaments in ORLS; (b) a random sample of 500 patients selected from the self harm monitoring files at the hospital (12 patients were not eligible for inclusion in ORLS and were therefore excluded from the rest of the study). MEASUREMENTS AND MAIN RESULTS: The recorded diagnosis was compared on the records selected from the two files. Of the 1123 events of poisoning identified in ORLS, 1081 (96.3%) were correctly coded as poisoning and 1065 (95%) of these were deliberate self poisoning. Of the 488 cases from the monitoring files, 467 (95.7%) of all cases had a correct diagnosis of injury or poisoning on the ORLS file. Of the 453 poisoning cases 436 (96.2%) were correctly recorded in ORLS. CONCLUSIONS: Deliberate self poisoning in adolescents can be identified through routinely collected hospital statistics. A very high percentage of the diagnostic information on poisoning in ORLS files is correctly recorded.

Life events and difficulties preceding stroke.

Life events and difficulties were recorded for the year before stroke, using a standardised semi-structured interview, in 113 surviving patients seen after their first ever in a lifetime stroke. An age and sex-matched control group (n = 109) was also interviewed about the preceding year. The stroke patients reported fewer non-threatening events and events with only a short-term threat, while difficulties were reported with equal frequency by the two groups. However, events which were severely threatening in the long-term were significantly more common in the stroke patients (in the 52 weeks before stroke 26% versus 13%, odds ratio 2.3, 95% confidence interval 1.1-4.9). The increased rate was apparent throughout the year and not just in the weeks immediately before stroke onset. The number of stroke patients experiencing severe events in the follow up year fell to the level found in the control group. Recognised risk factors for stroke were found equally in those patients with and without severe events before onset, except that hypertension was rather less common in the patients who had experienced a severe event. It therefore appears that severe life events may be one of the determinants of stroke onset.

Couples referred to a sexual dysfunction clinic. Psychological and physical morbidity.

Two hundred couples referred to a sexual problems clinic were assessed in a standardised way for their suitability for sex therapy. The assessment focused on the nature of the sexual dysfunction, motivation for treatment, marital and relationship problems, psychiatric status, and physical problems. Approximately one-third of the couples were found to have significant marital and relationship problems, and more than 30% were suffering from psychiatric disorders, although these were usually of mild to moderate intensity. A third of males and 18% of females were suffering from physical disorders likely to contribute to the sexual dysfunction. Patients who were offered sex therapy and who completed their course of treatment were more likely to show high levels of motivation and an absence of physical disorders, marital relationship problems and psychiatric disorder. There should be careful assessment of couples suffering from sexual dysfunction before specific treatment is offered.

Single-photon emission computerised tomography (SPECT) in schizophrenia.

SPECT studies were carried out on three occasions in a woman with schizophrenia. Marked 'hypofrontality' was demonstrated during an acute phase of illness. A study during remission was within normal limits, but some return of the original defect was noted in a subsequent relapse. These findings parallel those found in PET studies of schizophrenia.

Self-poisoning in adolescents. Hospital admissions and deaths in the Oxford region 1980-85.

Linked hospital and death records for 10-20-year-olds admitted with a diagnosis of poisoning were analysed. Between 1980 and 1985 there was a significant decline in admission rates, which was mainly attributable to a decline among 16-20-year-old females. There was no evidence of a decline in the admission rates among 12-15-year-olds. Ten per cent of the study population had at least one further hospital admission for poisoning during the mean follow-up period of 3.6 years. Female admission rates were substantially higher than those in males but readmission rates, given a first admission, were similar. The death rate in the study cohort was significantly higher than would be expected in the general population of this age and nearly all the deaths were from violent or unnatural causes.

Emotionalism after stroke.

OBJECTIVE: To estimate the prevalence of emotionalism after stroke, to assess its relation with other mood disorders, and to identify clinical variables with which it is associated. DESIGN: Descriptive study of a cohort of patients consecutively entered on a community stroke register. SETTING: Community based research project. PATIENTS: A total of 128 patients who had suffered first ever stroke. INTERVENTIONS AND END POINTS: Patients were interviewed by a psychiatrist at 1, 6, and 12 months after stroke. Mood state was assessed by standardised semistructured interview (present state examination) and self report (Beck depression inventory). Intellectual impairment was assessed by mini mental state examination and Frenchay aphasia screening test. In addition, stroke lesions were localised by computed tomography. MAIN RESULTS: Emotionalism was reported by 13 of 89 patients (15%) at one month, 25 of 119 (21%) at six months, and 12 of 112 (11%) at 12 months after stroke. Patients with emotionalism had higher scores on both measures of mood disorder (at 6 months: mean Beck score 10.5 v 6.4; present state examination score 7.2 v 5.1) and more diagnosable psychiatric disorder (at 6 months: 40% v 14%; odds ratio 4.2, 95% confidence interval 1.5 to 11.9). Almost all episodes were provoked by clearly identified and appropriate emotional experiences. Patients with emotionalism also had more intellectual impairment and larger lesions on computed tomography. Lesions in the left frontal and temporal regions were particularly associated with emotionalism: at 6 months 8 of 14 patients (57%) with such lesions had emotionalism compared with 10 of 52 (19%) of those with lesions elsewhere (odds ratio 5.6, 95% confidence interval 1.4 to 22). CONCLUSIONS: Emotionalism is common after stroke. It is neither emotionally meaningless and inappropriate, nor is it found mostly in patients with bilateral brain damage. Emotionalism is associated with symptoms of a more general mood disturbance and is found especially in patients with left frontal and temporal lesions.
