Afro-American women, poverty and mental health: a social essay.

The experience of poverty can be a risk factor for mental illness. Afro-American women are disproportionately represented among the poor, the majority of whom are single mothers and heads of households who are concentrated in the secondary labor market and the secondary welfare system. These economic and social factors can engender stress and can limit opportunities for its resolution or for the gratification of psychological needs. The consequences can range from mild emotional distresses to severe mental illnesses. Recommendations for improving mental health status include public mental health promotion and education programs, and social, economic and political actions such as increased and better quality employment opportunities and educational system reforms.

The effects of neurohypophysial hormones on the vascular resistance of the isolated perfused gill of the European eel, Anguilla anguilla L.

Arginine vasotocin (AVT) and oxytocin (OXY), in the dose range of 2 X 10(-13)-2 X 10(-8) mol, were found to be potent vasoconstrictors of the arterioarterial pathway of isolated perfused eel gills. AVT was significantly (P less than 0.05) more potent than OXY, as indicated by the results of both dose- and concentration-response curves. Isotocin (IT) and arginine vasopressin (AVP) were unable to elicit a vascular response at doses of up to 2 X 10(-8) mol. The arteriovenous component of branchial flow was not affected by these four peptides. Results from constant-pressure head and constant-flow preparations yielded similar results.

Identification of beta-adrenergic receptors in teleost red blood cells.

Beta-adrenoceptors have been identified in eel erythrocyte membranes using [3H]dihydroalprenolol binding. These receptors exhibit a mean dissociation constant (KD) of 1.36 nM and a mean maximum number of binding sites (Bmax) of 315 fmol/mg protein. These receptors do not appear to belong to the beta 1-subtype.

The uses of hopelessness.

If most emotional problems, like most medical problems, are caused by bad luck as well as by factors over which man has control, then those who suffer from such problems must accept a burden of helplessness. When patients and their families overuse theories of causality to avoid accepting their helplessness and to create an illusory sense of human control, unjust assignment of responsibility and excessive expectations for change may erode self-esteem and make change more difficult. The authors present examples of interventions that challenge the overuse of theories of causality. Although these interventions aroused hopelessness, they also fostered realistic hope and change.

Training psychiatric residents in chronic care.

Because of recent advances in the care of the chronically mentally ill, psychiatric residents need to have more specialized training in the treatment of this group of patients. The Massachusetts Mental Health Center has developed a training program in chronic care for psychiatric residents that is a combination of didactic presentations and placements in programs serving chronic patients. In learning to treat the chronically mentally ill, residents face a variety of clinical, countertransference, and supervisory issues. They must learn to conduct therapy that is rehabilitation-based; to combine their role as medical doctor with their role as psychiatric specialist; to work with a multidisciplinary team; and to coordinate patient care among serveral community agencies.

The five-year survival rate in urban patients with ovarian carcinoma.

The 5-year survival of 253 patients with ovarian malignancy of epithelial origin is reviewed. Although this is closely related to the clinical stage at presentation, the overall survival is poor, because the majority present with disease which has spread beyond the pelvis. There are more deaths in the first 2 years after diagnosis; thereafter the survival curve gradually flattens off and becomes almost horizontal during the 4th and 5th years.

Success or failure: psychotherapeutic considerations for women in conflict.

The authors describe conflicts experienced by women who request therapeutic intervention because of symptoms of depression, anxiety, marital discord, difficulty in asserting themselves, or inability to complete work that would lead to advancement. They discuss the developmentally based difficulties experienced by women in making career choices, advancing their careers, and facing midlife issues. The therapist who deals with such patients must be aware of reality-based factors and of his or her own values and attitudes as they influence choice of therapeutic approach.

Transnasal hypophysectomy.

A transnasal trans-sphenoidal surgical approach to the pituitary gland is described. The operative and post-operative experiences with the use of this technique on 21 patients with hormone-dependent malignant disease are reported. In 2 patients the procedure was abandoned because of intrasellar haemorrhage and in 1 an empty sella was found. Fifteen patients developed diabetes insipidus and 1 patient died in the postoperative period.

Hormonal therapy of breast cancer with special reference to Masteril therapy.

From 1968 to 1972, a trial of a new agent, drostanolone propionate (Masteril), was conducted. This agent was tested against oophorectomy in a group of premenopausal patients, against nandrolone phenylpropionate (Durabolin) in a perimenopausal group, and against ethinyl oestradiol in a postmenopausal group. In the premenopausal group, 44% responded to Masteril and 22% to oophorectomy. In the perimenopausal group, 34,5% responded to Masteril and 39% to Durabolin. In the postmenopausal group, 57% responded to oestrogens and 38,5% to Masteril. The side-effects of Masteril are generally not serious and rarely contra-indicate its use. Masteril has been shown to be a useful and safe agent for all age groups, even though it may appear to be less effective than oestrogens in the postmenopausal patients.
