Benefits and problems of routine laboratory investigations in adult psychiatric admissions.

A survey of laboratory investigations in the management of 1007 non-geriatric admissions to a district general hospital adult psychiatric unit showed a wide variation in the number of tests performed, and in the abnormal proportion between test types. Despite a policy of screening on admission, 40% of admissions had no tests. Physical illness attributable to mental illness was common, but rarely serious and usually apparent clinically. Mental illness attributable to physical illness detected by laboratory tests was rare: five cases of thyroid disease in women with affective disorder, and two cases of chest infection with raised white cell count in sustained mania. The findings show that tests are frequently used in circumstances where the result is of no apparent value. Test use might be improved by restricting screening to thyroid function and laboratory urine analysis, each in women. There are particular indications for white cell count in sustained or unexplained relapse of mental illness, and for syphilis serology when disinhibition may have exposed the patient to infection.

Localization of a susceptibility locus for schizophrenia on chromosome 5.

Schizophrenia is a common disorder with a life time prevalence of approximately 1 per cent. The illness often develops in young adults, who were previously normal, and is characterized by a constellation of symptoms including hallucinations and delusions (psychotic symptoms) and symptoms such as severely inappropriate emotional responses, a disorder of thinking and concentration, erratic behaviour as well as social and occupational deterioration. A considerable proportion of the variance in the liability to develop schizophrenia may be genetic, but segregation analysis, to establish a mode of transmission, has not produced a consistent result. One of these studies was carried out in Iceland and made use of the large family size and extensive geneaological information present in that country. Here we demonstrate genetic linkage of two DNA polymorphisms on the long arm of human chromosome 5 to schizophrenia in seven British and Icelandic families with multiple affected members. The results indicate the existence of a gene locus with a dominant schizophrenia-susceptibility allele. Inheritance of the allele in the families studied suggests that it may also predispose to psychiatric conditions such as schizophrenia spectrum disorders and a variety of other disorders. This report provides the first strong evidence for the involvement of a single gene in the causation of schizophrenia.

Thyroid disease and mental illness: a study of thyroid disease in psychiatric admissions.

The notes of 1007 consecutive admissions to a District General Hospital adult psychiatry unit were examined retrospectively to establish the role of the thyroid disease detected in routine management. Thyroid function tests were performed on 300 admissions, leaving 707 untested. Ten had abnormal results (3.3% of admissions tested), accounted for by nine patients with affective disorder. Two of the nine settled spontaneously, but seven cases (2.3%) had sustained abnormality. Five of the seven had a known history of thyroid disease, leaving two new findings of hypothyroidism who presented with no clinical signs other than their mental illness (0.7% of admissions tested). In five cases, which included the two new findings, the thyroid disease had been judged to precipitate the mental illness. All cases except one transitory abnormality occurred in females. When the results of this and other surveys are compared with the figures for thyroid disease in the general population, the value of screening psychiatric patients seems questionable. However, diagnosis is important in a few cases where thyroid disease apparently contributes to the mental illness. For psychiatric patients aged up to 65, elimination of unnecessary thyroid function tests without sacrificing detection may be possible by restricting use to female patients with affective disorder, patients with a past or family history of thyroid disease or with presenile dementia. Abnormal results obtained during the acute phase of the illness may be transitory and require confirmation.

Fat necrosis of the breast following lumpectomy and radiation therapy for early breast cancer.

Between January 1980 and December 1985, 121 patients with early breast cancer were treated in the Department of Radiation Oncology at Westmead Hospital by external beam irradiation and an iridium wire boost following "lumpectomy". After a median follow-up of 26 months, 14 patients have developed recurrent masses in the treated breast. In four, recurrent carcinoma was strongly suspected and subsequently confirmed by fine needle aspiration biopsy, but in only two was a subsequent salvage mastectomy possible. The remaining 10 patients developed a nodule which was usually tender. With three exceptions, the nodule was at the primary tumour site and developed 4-43 months after treatment. In seven, tumour recurrence was suspected but not confirmed by biopsy and the other three were accepted as having post-treatment "radiation fibrosis". Excision biopsy was undertaken in eight of the 10 patients. Another patient underwent partial mastectomy for presumed local recurrence. The histological appearance in all cases was similar, with areas of fat necrosis and fibrosis with atypical stromal fibroblasts. Suture material was present microscopically in eight patients and was noted macroscopically (that is, by mammogram) in the one patient who did not undergo surgery. This complication is most likely caused by a combination of surgical and radiation factors. The difficulty in management is differentiation between tumour recurrence and a benign condition.

Early breast cancer: cosmetic and functional results after treatment by conservative techniques.

Between January 1980 and December 1985, 121 patients with early breast cancer were referred to the Department of Radiation Oncology at Westmead Hospital for radiation therapy following initial tumour excision. After a median follow-up of 26 months, five patients developed a loco-regional recurrence (4%) and nine developed metastatic disease but with local control. There were 105 eligible patients who were sent a letter/questionnaire which included: a request to attend a clinic, to allow an objective assessment of the cosmetic result of the treated breast by two clinicians, questions regarding breast function as it affected quality of life, and a request that they undertake a self-assessment of the treated breast from a cosmetic point of view. Seventy-six patients attended for assessment of the following factors: whether surgery was optimal as determined by predefined criteria, measurement of breast oedema, arm oedema, breast retraction and telangiectasia, and an overall cosmetic assessment performed independently by both a radiation oncologist and surgeon. A physician not involved in management undertook a cosmetic assessment using standard photographs. Approximately 20% of patients replied that their choice of clothing had been affected by treatment, 10% were embarrassed and 70% experienced some continuing tenderness or discomfort in their treated breast. The extent of surgery was judged to be suboptimal in 22% but that proportion increased to 34% of cases referred from external clinics. The overall incidence of moderate or severe breast oedema was 9%, breast retraction 50%, telangiectasia 16% and arm oedema 21%. Those patients with longer follow-up (i.e., greater than 36 months) had a higher incidence of breast retraction (67%), telangiectasia (30%) and arm oedema (33%) but less breast oedema (7%). As expected, the patients rated the appearance of their breast more favourably than did clinicians. Overall, the result was rated as good or excellent by 75% of patients compared with 55% when the assessment was made by a surgeon or radiation oncologist. The main factor identified as contributing to a poor cosmetic result was the area of the iridium implant. The area of implant was larger when suboptimal surgery had been carried out, the main component of which was excessive length of scar.

Depression among men made involuntarily redundant.

Ninety-eight men aged 25-50, who were unemployed because of involuntary redundancy and out of work for 2-18 months, completed the Beck Depression Inventory (BDI) and the General Health Questionnaire (GHQ-30). Their scores were compared with those of a group of employed men matched for age and social class. The mean GHQ score for the redundant men was 13.0, compared with 4.0 for the employed group. The mean BDI score was 11.1 for the redundant group and 5.6 for the employed group. Eighteen per cent of the redundant men, compared with 6% of the employed group, scored 18 or more which are scores corresponding to those in depressive illness. We conclude that the prevalence of depressive illness may be increased among redundant men.

Why teetotallers abstain.

Drinking practices and attitudes to alcohol among the members of a Southampton church were investigated by questionnaire (602 subjects) and by interviews (126 subjects). Teetotallers were older than drinkers, and included a higher proportion of women. They perceived their childhood upbringing and the teaching of the Bible as the main factors influencing them to abstain. Both teetotallism and alcoholism were more common among relatives of teetotallers than among relatives of social drinkers.

Legal and administrative influences on the English suicide rate since 1900.

We examined the hypothesis that changes in the suicide rate of England and Wales since 1900 are an artefact of changes in the process of classifying violent deaths. Four potential sources of artefact were considered: (1) the reliability of the procedure for investigating suspected suicides; (2) coding by the Office of Population Censuses and Surveys; (3) changes in the law; (4) High Court decisions on suicide. None of these can explain the large observed fluctuations in the suicide rate.

Influence of coroners' officers and pathologists on suicide verdicts.

Three-hundred-and-thirty cases of unnatural death, leading to 110 open verdicts, 110 verdicts of suicide and 110 of accident, from the Inner West London Coroner's District have been examined to see if particular coroner's officers or pathologists were associated with disproportionate numbers of suicide verdicts. No significant deviations from the expected numbers were found. Coroner's officers probably share common ideas about the features defining suicide, and so do pathologists.
