Religious beliefs and practices among 52 psychiatric inpatients in Minnesota.

The authors studied the religious beliefs, practices, and experiences of 52 psychiatric inpatients. The rate of belief in the major tenets of faith (God, the Devil, and an afterlife) was uniformly high and in accord with national and local public poll results. Patients with depressive and anxiety disorders tended to score lower than those with other diagnoses on a wide variety of indexes of religion. The authors conclude that religion is an important factor in most patients' lives and that individual inquiry and systematic research into this neglected area are both feasible and important.

Depression and posttraumatic stress disorder in Southeast Asian refugees.

The authors report on 404 Southeast Asian refugees seen at a community clinic. Approximately three-quarters of these patients met DSM-III criteria for major depressive episode, and 14% had posttraumatic stress disorder. Complaints of pain and sleep disturbances were the predominant presenting symptoms. Most of the men were married, but more than 40% of the women were widowed. Between 15% and 30% of the patients reported specific traumatic experiences either in their homeland or during their escape. Widowhood and such traumatic experiences were positively correlated with more symptoms of depression and anxiety.

[The application of additives and compounds to meat products].

From the economic and perspective point of view the application of compounds and extenders in meat products represents an unavoidable world-wide development. The present study reviews additives and compounds for sausages and other comminuted meat products which have an influence on water binding and fat emulsifying. In the paper details and results of the patent publications published since 1960 are presented and discussed.

Water binding of proteins in the processing frankfurter-type sausages. Part. 1. Water-binding ability of freeze-dried meat fractions containing myofibrillar and stromal proteins.

As soon as possible and 48 h after slaughter respectively, from both blade-bone muscle groups of cattle and pig carcasses the "thick pieces" were excised, extracted, and fractionated. Residues and precipitates from water and salt extracts resulted were freeze-dried, and an improved Baumann capillary suction apparatus was used to measure their water binding capacity (WBC) with and without addition of 2% sodium chloride and/or heating to 80 degrees C. With one exception the WBC results followed a relative pattern demonstrating the final residues (stromal proteins and leavings of myofibrillar proteins) binding the highest amount of added water, precipitates of dialysis (mainly containing myofibrillar proteins) a remarkable amount and powdered meats the least. As scanning electron micrographs confirmed, there were no fibrous structures in the precipitates resulted from dialysis of salt solutions (1.0 mol/1). Heating decreased the spontaneous water uptake of all fractions. Addition of sodium chloride had only a noticeable capillary-suction and swelling effect on unheated samples. Hence swelling of undissolved protein structures (extraction of myosin and possibly of actomyosin) is therefore not the only way for water binding in frankfurter-type sausages.

Evaluation of the water binding properties of meat binders, substitutes and extenders by different physical and chemical methods.

From investigations concerning water binding capacity measured by an improved Baumann technique, differential scanning calorimetry, nitrogen solubility, moisture sorption isotherms, specific surface area, and specific volume of powdered proteinaceous materials proposed as binders and/or substitutes in frankfurter-type sausages it has been concluded, that in water uptake on the Baumann apparatus activation energies comparable to diffusion processes and enzymic reactions and not comparable to chemical reactions are favoured. Water taken up on the Baumann apparatus predominantly is freezable, that is free and only physical bound water. Powdered proteinaceous materials do not take up water discontinuously by strictly limited surface areas and perforations. At first the geometrical surface is completely wetted. Not till then water will be bound by capillary effects. Thus only up to a certain degree of moistening (aw 0.92) the more water is bound, the lower the material's solubility. Afterwards solubility, capillary suction pressure and swelling (increasing pore space) will compete.

The relationship of borderline personality disorder to the affective disorders.

The proposition that Borderline Personality Disorders (BPDs) are atypical forms of affective disorder is reviewed in the light of pharmacological, outcome and clinical studies. The case can be summarized briefly as follows: that the basic underlying cause of borderline symptomatology is an effective disorder; that mood disturbance, which is viewed as primarily biological, is more important than developmental experience and life events in maintaining borderline personality features; that therapies aimed at treating the mood disorder should therefore be expected to relieve the personality disorder. However, the pharmacological studies suggest that antidepressant medications have been largely ineffective in treating well defined BPD, except in the presence of coexisting depressive disorder. Indeed low dose antipsychotics have a demonstrated efficacy in the treatment of BPD, which does not strengthen the case for an affective etiology. Follow-up studies of BPDs suggest that dramatic characterological features seen at the time of index hospitalization tend to recede by the time patients are in their 30s, that major affective disorders fail to emerge over time, and that long-term marginal functioning derives from long-term maladaptive patterns across a variety of areas. Clinical studies suggest that 20-60 per cent of patients with BPD have a concomitant depressive disorder. Conversely the prevalence of personality disorders in depressions varies with depressive category, with considerably higher incidence of personality disturbance found in non-endogenous depression. The high rate of coexistence of these two disorders does not imply causality or primacy, in the sense that it is the affective disorder which brings out and causes the personality disorder. The review concludes that the assertion that BPD represents atypical affective disorder begs the possibility that it is precisely in having borderline features that they are atypical, and hence distinct.

The adolescence of a thirteenth-century visionary nun.

Among the most notable features of the religious revival in western Europe in the early thirteenth century was the development of mysticism among the nuns and religious women of the lowlands. As scholarly attention becomes increasingly focused on this group of remarkable women, the question arises whether a psychiatric viewpoint has something of value to offer to the understanding of such individuals and the culture in which they struggled. The methodological and intellectual problems inherent in examining the life of a thirteenth-century mystic with a twentieth-century empirical frame of reference are illustrated in this study of the adolescence of Beatrice of Nazareth. Beatrice's stormy asceticism, ecstatic states and mood swings lend themselves to potentially competing hypotheses regarding the spiritual and psychopathological significance of her adolescent development and eventual life-course. Common grounds for reconciling these alternative models are discussed.

A survey of homeless adults in urban emergency shelters.

Following a review of several studies of homeless populations, the authors describe a survey of 68 homeless adults in eight urban emergency shelters in Hennepin County, Minnesota. The results indicated impressive rates of mental illness, alcoholism, minor criminality, and chronic medical and dental problems. More significant, the authors believe, both for the homeless and for public policy planners, is that a majority of the interviewees were disconnected from supportive social networks and were underutilizing medical and welfare programs for which they were eligible. Almost 40 percent of those with chronic health problems were receiving no medical care, and only 6 percent were receiving mental health services, although more than 50 percent needed such care. The authors compare the findings with those of studies discussed in the literature review.

Sin and mental illness in the Middle Ages.

The modern stereotype that in the Middle Ages there was a general belief that mental illness was caused by sin is reviewed. The authors examined 57 descriptions of mental illness (madness, possession, alcoholism, epilepsy, and combinations thereof) from pre-Crusade chronicles and saints' lives. In only 9 (16%) of these descriptions did the sources attribute the mental illness to sin or wrongdoing, and in these cases the medieval authors appeared to use this attribution for its propaganda value against an enemy of their patron saints, their monastery lands, or their religious values. The medieval sources indicate that the authors were well aware of the proximate causes of mental illness, such as humoral imbalance, intemperate diet and alcohol intake, overwork, and grief. The banality that, since God causes all things he also causes mental illness, was only used by medieval authors under special circumstances and in a minority of cases. It does not constitute evidence of superstitious and primitive notions about mental illness in the early Middle Ages.

Consultation outcomes. The psychiatrist as consultee.

The frequent coexistence of psychiatric and medical illness supports the need for excellent medical care on inpatient psychiatric services. Effective use of consultation is an important element in ensuring this care. In our study of medical-surgical consultation to an inpatient psychiatric service during a two-year period, outcome variables, such as frequency of and concordance with drug and diagnostic action recommendations, were determined and compared with similar data for psychiatric consultations to medical-surgical services. Thirty-eight percent of cases received a consultation. Patients seen by a consultant had a longer hospital stay. Twenty-seven and forty-six percent of consultantions contained a drug or a diagnostic action recommendation, respectively. The concordance of psychiatric consultees was 79% for drugs and 75% for diagnostic action recommendations. Comparison with medical-surgical consultations done by psychiatric consultants revealed important important differences and similarities.

Discriminating borderline disorder from other personality disorders. Cluster analysis of the diagnostic interview for borderlines.

The statistical technique of cluster analysis was applied to 252 hospitalized patients' scores on the 29 statements of the Diagnostic Interview for Borderlines. We found that this statistical treatment could reliably differentiate borderline disorder from other personality disorders. Two subtypes similar to Spitzer's schizotypal and unstable subtypes emerged.

When psychiatrists are liable: risk management and violent patients.

In an era of rapid discharge and community treatment, psychiatrists must assess, with insufficient information, their patients' potential for committing a violent act outside of the hospital every time they authorize a pass or a discharge. The authors review court decisions on prediction of dangerousness and research data on the risk of homicide, assault, and suicide among released mental patients. They then discuss a risk-management approach to decision-making that consists of three components--risk assessment, risk evaluation, and risk reduction. The authors also provide a decision table that clinicians can use to identify factors that suggest a high risk of violence in a patient's current status, history, and treatment response.
