Neuroendocrine and personality variables in dysthymic disorder.

In an attempt to characterize a subgroup of depressed patients diagnosed as having dysthymic disorder, the authors gave them two commonly used biological tests for depression and several personality inventories and compared the results with those from age- and sex-matched normal control subjects. There were no significant differences between the 11 early-onset dysthymic disorder patients and the 11 controls on the dexamethasone suppression test or the thyrotropin-releasing hormone test. The personality questionnaires, however, showed that the dysthymic disorder patients were significantly more neurotic, extrapunitive, and intrapunitive and had significantly lower self-esteem than the control subjects.

Suicide and psychiatric patients.

The social and psychiatric risk factors associated with suicide in patients with different psychiatric disorders are reviewed. Suicide among emergency room attenders, inpatients, and outpatients is considered. The assessment and treatment of suicidal patients and the prediction and prevention of suicide are discussed.

Serum protein polymorphisms in selected areas of West Bengal, India.

Serum proteins like haptoglobins and transferrin and total protein types were determined in healthy donors from West Bengal, with different levels of industrialisation and urbanisation, by disc gel electrophoresis. The frequency of the allele Hp2 was much higher in all the areas. A highly significant difference was observed between industrial and agricultural areas. However, the differences among the industrial districts were not significant except between the districts of Howrah and 24-Parganas.

Self-destructive dermatoses.

It appears certain that the causes of self-destructive dermatoses are many and complex. The disorder spans diagnostic categories and varies from unconscious picking at the skin to severe self-destructive actions. Although not limited to any one diagnosis, skin disorders appear to be more prevalent in depression. This association may involve activation of the hypothalamic-pituitary-adrenal axis commonly found in depression. Two specific types of commonly occurring dermatoses-neurotic excoriations and dermatitis artefacta-are reviewed in this article. The major distinction of these disorders centers on whether the patient can admit to self-mutilation. Because of the difficulties in dermatitis artefacta with insight and body-image, it has been compared with anorexia nervosa. Often, dermatitis artefacta coexists with anorexia nervosa. In both disorders, neurotic excoriations and dermatitis artefacta, the personality style tends to be introverted with emotional immaturity. These patients have difficulty when they are under stress; the problem is compounded because of poor communication skills. Pharmacotherapy is of limited usefulness, and psychotherapy is often times hindered by strong resistance to exploring long-standing emotional issues. Once an alliance is established with the therapist, however, these issues may be examined. Prognosis is variable but does seem to directly correlate with the duration of the illness. Young individuals may experience alleviation of symptoms after one session of psychotherapy, whereas older patients may never have resolution. Dermatologic abuse involving psychosis has many presentations; one of the most common involves infestation. Organic causes must always be excluded as part of the differential diagnosis. In schizophrenia, this presentation has one of the highest incidences of suicide.(ABSTRACT TRUNCATED AT 250 WORDS)

Suicide in doctors.

This article critically reviews the evidence as to whether or not those who choose medicine for a career have an increased risk of suicide. Evidence is examined in relation to medical students, physicians, physicians' wives, women physicians, psychiatric residents, and psychiatrists.

[Interruption of the aortic arch and malformative cardiac lesions requiring repair under extracorporeal circulation. Apropos of 3 cases].

Interruption of the aortic arch is practically always associated with intracardiac malformations of variable complexity, at the least, a ventricular septal defect. Surgery is usually performed in two stages: aortic repair and pulmonary artery banding after intravenous prostaglandin administration. The second stage comprises debanding and repair of the intracardiac lesions under cardiopulmonary bypass. However, in some cases, interruption of the aortic arch is associated with intracardiac lesions which necessitate correction under cardiopulmonary bypass from the onset, this was the situation in two of the three cases described by the authors: aorto-pulmonary window, a lesion which can only be corrected under circulatory arrest and deep hypothermia. One of these two children, operated in the neonatal period, did not survive: the other, operated at 6 weeks, had an excellent result. In the third case, the association of tricuspid atresia and a restrictive ventricular septal defect necessitated enlargement of the septal defect and therefore, open heart surgery under circulatory arrest; the results were favourable.

Family history of suicide in affective disorder patients.

In a consecutive series of 137 affective disorder patients with a family history of suicide, bipolar disorder formed the biggest group. Of the 137 patients, 61 (44.5%) had made a total of 117 attempts at suicide. The patients who had attempted suicide, compared with those who had not, had a significantly earlier age of onset and longer duration of illness, and more of them were unmarried.
