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)

The clinical features in six patients who developed schizophrenia or schizophrenic form illnesses in the context of their anorexia nervosa were described. The patients appeared to have retained their anorectic psychopathology even in their psychosis.

Immunoreactive somatostatin, bombesin, and cholecystokinin were measured in cerebrospinal fluid of normal subjects and patients with anorexia nervosa, depression, mania, and schizophrenia. Somatostatin-like immunoreactivity was decreased in anorexic and depressed patients. Bombesin-like immunoreactivity tended to be decreased in schizophrenics. Cholecystokinin-like immunoreactivity did not differ between groups. These data suggest a possible function for neuropeptides in regulation of human behavior.

In this paper we have reported the results of studies in psychiatric patient groups using the strategy of measuring opioid activity and beta-endorphin (ir) in CSF. Our findings do not lend support to the notion of excess endorphin activity in schizophrenia, but rather suggest the possibility of a decrease in endogenous opioid activity in some schizophrenic patients. In affectively ill patients our data suggest that there may be a relative change in endogenous opioid system activity across state change in manic-depressive illness. Who also found a relationship between nurses' ratings of anxiety and CSF opioid activity in depressed patients, although it is unknown whether this directly relates to the pathophysiology of this symptom, or is related to stress response. The relationship between CSF opioid activity and HPA axis activity, as reflected by urinary free cortisol excretion, supports the notion of important physiologic relationships between these systems and raises the issue of a role for the endogenous opioid system in the abnormal activation of this system in depression. Finally, the finding of increased CSF opioid activity in anorexia nervosa patients when a minimum weight coupled with data relating endogenous opioids to eating behavior raises interesting questions regarding a possible involvement of the endogenous opioid system involvement in this illness.

Adolescent psychiatry as a body of knowledge has shown encouraging growth in recent years, as research findings from general psychiatry have been added to new data on adolescent psychological and physical development. The author reviews recent findings on selected topics in adolescent psychopathology, including adaptive disorders, obsessive-compulsive disorders, phobias, attention deficit disorders, depression, manic-depressive illness, suicidal impulses, schizophrenia, anorexia nervosa, and borderline states. He also outlines findings on normal adolescent development and discusses the problems of diagnosing children and adolescents with psychological problems. Studies in anxiety, attention deficit, and conduct disorders, he says, are yielding important new findings by combining biological and psychological insights.

The measurement of endorphins in body fluids has been an important advance in clinical research attempting to link the endogenous opioid system to psychiatric illness and symptomatology. The consideration of methodologic differences in assay technique and in clinical methods is important in evaluating results of studies. Whereas findings in early clinical studies supported the notion of increased endorphin system function in patients with schizophrenia, cumulative data from the considerable number of studies carried out throughout world centers have been unable to demonstrate a consistent abnormality in levels of endorphins in CSF or plasma of patients with schizophrenia. Among the affective disorders, data suggest the possibility of relative changes in levels of opioids within individual manic-depressive patients when studied across state change from depression to mania. In studies of depressive illness there is accumulating evidence that the endogenous opioid system may relate or contribute to abnormality of the HPA axis. In our work measuring opioids in CSF we have observed relationships between anxiety and CSF opioids in normals and psychiatric patients and changes in CSF opioid activity in patients with anorexia nervosa accompanying weight change. These data are consistent with other evidence linking endorphins to CNS noradrenergic systems and to biologic response to stress.

Recently, anorexia nervosa has received much attention in the scientific and lay press. As a result there is a danger that the other emotional disorders that can present with weight loss and vomiting will be overlooked. Case examples are presented for anorexia nervosa, conversion disorder, schizophrenia and depression. The presentation and treatment of these four disorders are compared.

In a sample of 130 consecutive patients with a lifetime diagnosis of anorexia nervosa and/or bulimia, 17 displayed psychotic symptoms. In 16 patients, these symptoms appeared attributable to major affective disorder or schizo-affective disorder, while in one, they appeared to represent factitious psychosis. No cases of schizophrenia or organic psychosis were identified.

The author presents four criteria for the diagnosis of anorexia nervosa and reviews laboratory studies, follow-up study, family history, and differential diagnosis of anorectics. Current findings on other related conditions such as affective disorder, medical illness accompanied by weight loss, somatization disorder, and schizophrenia are discussed.

Fifty patients with severe weight loss thought to be caused by anorexia nervosa were hospitalized for evaluation. On the basis of psychiatric history and mental state examination, they were divided into three diagnostic categories: anorexia nervosa; other. The MMPI of patients with anorexia nervosa was markedly abnormal, with highest peaks on the D (depression), PT (obsessionality and anxiety), and SC (schizophrenia) scales. This profile was similar to that of patients with obsessional symptoms and neurotic depression, but differed significantly from the profile of patients with low weight but normal mental state examination. These findings suggest that starvation alone does not explain the psychopathological symptoms similar to those with depressive and obsessional symptomatology. The MMPI is useful in differentiating anorexia nervosa from those with lowered weight from nonpsychiatric causes, but does not by itself provide a distinct diagnostic category when compared with neurotic disorders having similar symptom clusters.
