Psychologically mediated abdominal pain in surgical and medical outpatients clinics.

Ninety-six patients complaining of recurrent or persistent abdominal pain were referred consecutively to a surgical clinic and a medical clinic, respectively. They were examined psychiatrically after their initial physical investigation. The psychiatric examination included rating scales for depression and anxiety, a personality inventory, life-events schedule, scale of verbal expressivity, and family and personal patterns of pain and invalidism. Only 15 patients (15-6%) had organic disorders that could be responsible for their symptoms. In the remainder, psychiatric factors were considered primarily responsible for their abdominal pain: 31 were depressed; 21 had chronic tension; in 17 hysterical mechanisms were prominent; and 12 were found to be unrecognised alcoholics. Follow-up at three and six months and recognition by 80% of the psychogenic group that a psychological explanation was plausible, confirmed the diagnoses, and over half responded favourably to psychiatric management. Features distinguishing the organic and psychogenic groups were delineated. Psychiatric assessment has a place among the investigations of non-acute abdominal pain; certainly it should not be condisered simply as "a last resort."

Presence of serotonin in the rat vas deferens: its influence on contractile responses.

Serotonin has been detected in the rat vas deferens. Increase in the serotonin concentration by exposure of the rat vas deferens to L-tryptophan occurs in vitro. p-chlorophenylalanine partly blocks the increase in serotonin concentration induced by tryptophan in vitro but not in vivo. Chronic sympathetic denervation induces an increase in 5-HT concentration. Responses of the vas deferens to transmural stimulation are depressed by pretreatment of rats with p-chlorophenylalanine, and the depression is reversed by incubation in vitro with 5-hydroxytryptophan or serotonin. Serotonin can enhance the response to transmural stimulation at low concentrations but has no effect at higher concentrations. Physostigmine-induced enhancement of the response to stimulation is depressed only by higher concentrations of serotonin. The results raise the question whether endogenous serotonin can act as a modulator of neurotransmission in the rat vas deferens.

The use of selected questions from the Symptom-Sign Inventory with long-stay psychiatric patients.

The Symptom-Sign Inventory was administered to 57 long-stay psychiatric in-patients with the object of selecting a group of questions which would stimulate the production of delusional or other psychotic material. The scoring of the responses as positive was made on verbal affirmative and other specific behaviours which were thought to indicate emotional impact. It was found that the ten questions selected compared favourably with longer questionnaires in discriminating schizophrenic from normal subjects and from those with organic brain disease. It is suggested that these questions might be included in brief assessment interviews on which day-to-day management decisions are made.

Women senior registrars in psychiatry: background and career intentions.

An inquiry was made of all women senior registrats in general psychiatry who were known to be planning to remain in psychiatry in this country. Most were hoping to work full or maximum part-time, and all except one were aiming for a consultant appointment in general psychiatry or one of the specialties. Many anticipated difficulties in realizing their ambitions because of being tied to one particular area on account of their husbands' employment. A number of solutions to this problem are suggested.

Pericarditis, pleural effusion, and pneumonitis with transient mitochondrial antibodies.

Four women with fever, arthromyalgias, pericarditis, pleural effusion, high erythrocyte sedimentation rates, and lymphopenia had mitochondrial antibodies in the serum in the absence of antinuclear antibody. Their illness lasted 5-12 weeks and the antibody test results became negative on remission. Absence of specific bacteriological findings, normal antistreptolysin O titres, resistance to antibiotics, and good response to steroids suggested that these cases represented a milder and less persistent form of the syndrome resembling systemic lupus erythematosus described by German authors.

Intravenous tranquillization with ECT.

Forty depressed in-patients for whom electro-convulsive therapy had been prescribed were rated before treatment on depression and anxiety scales. Side effects, post-operative agitation and retrograde memory impairment were assessed in each patient after each of several treatments. Results were compared when no tranquillizer was given and when either diazepam or haloperidol was administered intravenously immediately before the anaesthetic. It was found than when ECT was given without tranquillization, the incidence and severity of post-operative agitation and of side effects were significantly greater in those patients with a high level of anxiety before treatment. Both diazepam and haloperidol were found to be effective in subduing agitation and side effects in anxious, depressed patients, but with diazepam recovery time was longer.

Subjective side-effects of ECT.

The incidence of side-effects present 24 hours after electroconvulsive therapy was studied in 96 patients who between them received 500 treatments in a consecutive series. None of the side-effects occurred frequently: headache was experienced after 2-6 per cent and subjective memory impairment after 3 per cent of treatments. None of the unwanted effects held any serious physical threat. The aspect of ECT most disliked by the patients in this study, and mentioned by 16 per cent of them, was the fear of permanent memory upset.

[Effect of the steroid sex hormones on the LH and FSH responses to LHRH in the normal subject].

In man both basal gonadotrophin levels and the pituitary responses to LHRH remained relatively constant throughout life. In women the pituitary sensitivity varied in the menstrual cycle due to the typical cyclic variation of oestradiol and progesterone. The max delta LH increase to 100 mug LHRH was observed in the periovulatory period (183 +/- 41 mU/ml); it was also significantly higher in the luteal (49 +/- 7 mu/ml) than in the early follicular phase (18 +/- 3 mU/ml). The effect of exogenous sex steroid hormones taken as contraceptive drugs was then studied in 15 women. Significantly lower LH and FSH basal values as well as responses to LHRH were observed in 8 normal women under oral combined contraceptives. Conversely, in 7 women under oral sequential contraceptives, basal LH and FSH remained in the normal range. The LH-FSH responses were increased and delayed when these tests were performed during the period of estrogen treatment. Thus, with combined oral contraceptives, constant and high levels of estrogens and progesterone not only inhibit the LH peak, but also decrease the basal LH-FSH levels and responses to releasing hormone. Conversely, with sequential oral contraceptives, the low level of estradiol does not inhibit these responses and even enhances them. In menopausal women both basal and gonadotrophin responses to LHRH were increased indicating an important pituitary reserve. In menstruating women a significant estradiol increase is observed 2 and 4 hours after a 100 mug LHRH injection, both during the follicular and the luteal phases whereas progesterone increases only in the luteal phase. In men, testosterone was found to increase 4 hours after a 100 mug LHRH injection. These studies show that in normal subjects, sex steroid hormones are important regulators of the sensitivity of the pituitary responsiveness to releasing hormone.
