Over a 12-month period in 1985-1986, 325 cases of deliberate self-poisoning were admitted to the Princess Alexandra Hospital in Brisbane. This survey confirms that deliberate self-poisoning remains common, accounting for 19.6% of all admissions to the intensive-care unit, and 5.4% of all medical-ward admissions. In 232 (71.4%) cases formal psychiatric consultation occurred, and some form of follow-up was organized in 227 (69.8%) cases. In the total group, the female-to-male ratio was 1.5 to one. In the 325 cases, a total of 489 substances was consumed. Benzodiazepine agents were consumed the most often (39.5% of all substances), followed by antidepressant drugs (11.7% of substances) and paracetamol (7.2% of substances). Barbiturate drugs, which previously have been shown to be prominent in deliberate self-poisoning, accounted for only 1.6% of the substances that were used in this survey. Alcohol was consumed in almost one-third (31.1%) of cases. The diagnosis of adjustment disorder with depressed mood was the most-frequent primary diagnosis (64.8% of diagnosed cases), followed by personality disorder (16.7% of diagnosed cases), schizophrenia (5.5% of diagnosed cases) and major depression (3.7% of diagnosed cases). Nearly one-half (46.8%) of all cases involved a past history of deliberate self-poisoning. Comparison of the results of this survey with those of past surveys shows that the profile of deliberate self-poisoning is changing. Barbiturate usage has declined markedly with a reciprocal increase in benzodiazepine usage. A review of the prescribing pattern of antidepressant agents in groups of individuals who are at high risk of deliberate self-poisoning is suggested in the light of the frequency of this phenomenon.

One hundred forty-eight psychiatric inpatients, 12 outpatients, and 17 normal controls were given the 1.0-mg overnight Dexamethasone Suppression Test (DST), with salivary cortisol concentrations being measured as the dependent variable. Based on the Structured Clinical Interview for DSM-III, the patients were diagnosed as having major depression with melancholia (n = 21), nonmelancholic major depression (n = 50), mania (n = 15), schizophrenia (n = 32), dementia (n = 6), substance dependence/abuse n = 18), and miscellaneous (n = 18). Neither the melancholic major depressives nor the entire group of major depressives had significantly higher salivary cortisol pre- or postdexamethasone as compared with all the other patients combined, nor did the melancholic patients have significantly higher cortisol than the nonmelancholic depressives. The inpatients as a group had significantly higher pre- and postdexamethasone cortisol values than the normal controls; cortisol values for the outpatients were intermediate between these two groups. Illness severity (in the depressives), length of time in hospital before the DST, and medication regimen were all unrelated to DST outcome. Thus, in this study, the salivary cortisol DST showed little clinical utility in discriminating major depressives with and without melancholia from other patients with a broad range of psychiatric diagnoses. The test did distinguish between hospitalized psychiatric patients and normal control subjects and between depressed inpatients and depressed outpatients, indicating that hospitalization-related variables contributed to DST outcome.

Of 301 first-time admitted patients with delusional psychoses, 50 met DSM-III criteria for major depressive disorder (MDD), 33 schizoaffective disorder, depressive type (SADD), and 94 schizophrenia. At personal follow-up after 3-39 (mean 22) years, the SADD group was recorded in between on course and outcome variables, but closer to MDD. The findings in MDD and SADD were respectively: remission 66% vs. 42%, personality disorders 14% vs. 12%, anxiety disorder or alcohol abuse 2% vs. 6%, psychosis 18% vs. 36% (with bipolar development in 2% vs. 6%, paranoid disorder 2% vs. 3%, schizophrenia 4% vs. 3%). Chronic psychosis was recorded in 10% vs. 27%. No significant outcome difference was found between early onset MDD and SADD cases and those who fell ill at a higher age. The assumption that antidepressants may induce mania could not be confirmed. Normal premorbid personality seemed to predict a favourable course.

The existence of seasonal variations in the dexamethasone suppression test (D.S.T.) has been remarked. In a sample of 345 patients with affective symptomatology and various psychiatric diagnostics, patient with major depression have higher non suppression levels in spring and winter; a similar but stronger seasonal variations is observed in patients with melancholic and patients with psychotic syndrome showed a similar tendency. In patients with diagnostics different from depression (dementia, schizophrenia, mania, anxiety disorders), the non suppression level is higher in winter. Some similarities with the contributions of other authors are observed but in general disagreements are more frequent, which suggests us the influence of latitude and geo-climatic changes, since the seasonal variability can not be explained by means of seasonal changes in demographic or clinical variables, as diagnostic or psychiatric syndrome.

One hundred and seventeen biological mothers and 63 biological fathers of depressed and nondepressed, psychiatrically disturbed children and adolescents were interviewed with the Schedule for Affective Disorders and Schizophrenia-Lifetime Version. Diagnostic information was also obtained on 54 biological fathers who were unavailable for interview. Histories of depressive disorders and other forms of psychopathology were reported at high rates in the parents. Major depression was the most commonly reported disorder in interviewed parents of both sexes, but it was reported more often in mothers. Substance abuse and antisocial pathology was more prevalent in fathers. Depression in parents did not distinguish depressed from nondepressed probands, but maternal history of anxiety disorders, alcoholism and/or drug abuse, and suicidality did. Depressed probands were more likely than their nondepressed peers to have two parents with histories of depression. Mothers of younger patients had more substance abuse and suicidality in their histories than mothers of adolescents. They also reported earlier age of onset of depression and earlier age of entry into treatment.

To establish the differential indication of trazodone and to find the predictors of its efficacy, we conducted a study in which 45 patients with major depressive disorder and 75 patients with acute schizophrenia were randomly assigned under double-blind conditions to either 400 mg trazodone daily, 150 mg amitriptyline daily, 20 mg haloperidol daily, or placebo daily. At the beginning of the investigations, numerous variables (basic data, MMPI, AMDP, HAM-A, HAM-D) were documented and evaluated on days 3, 7, 14, and 21. In our study, trazodone proved to be as effective an antidepressant drug as amitriptyline. In group comparison, no antipsychotic action of trazodone in schizophrenic patients could be proved. Yet the trazodone treatment was clearly of less risk than the amitriptyline treatment. Under trazodone, provocation of schizophrenic symptoms, which occurred numerously under amitriptyline, was found only in one patient out of 17 schizophrenics. Related to anamnesis and characteristics of the schizophrenic patient, a predictor-variable concerning the antipsychotic effect was not found. It can be assured, however, that patients with depressive symptoms (regarding the entity classification) respond to trazodone. After only 7 days of trazodone treatment, a relatively reliable decision can be established as to whether a therapeutical success can be expected if treatment is continued.

A 3-year urban material of suicides in adolescents and young adults (age 15-29 years) was studied retrospectively by means of interviews with survivors (n = 58). Classification of mental disorders according to DSM-III-R showed that major depression was important as background to suicides in 41%, primary (22%) or secondary (19%) to other disorders. Adding major depression, depressive disorder, not otherwise specified, dysthymia and adjustment disorder with depressed mood gave a total of 64% depressive syndromes. Schizophrenia (14%) and borderline personality disorder (28%) constituted other relevant groups. Coexisting substance use disorder occurred in 47%. A majority of the subjects (72%) were known by psychiatric caregivers and 16% committed suicide during inpatient care.

The lifetime and current prevalence of depression and anxiety disorders was determined in 41 children with Crohn's disease, 12 children with ulcerative colitis, and 52 children with cystic fibrosis, using the Kiddie-Schedule for Affective Disorders and Schizophrenia interview. The lifetime prevalence of depression was 29% in Crohn's disease, 21% in ulcerative colitis, and 11.5% in cystic fibrosis. The difference in the prevalence of depression between Crohn's disease and cystic fibrosis was significant (p less than 0.05). The lifetime and current prevalence of dysthymia was significantly greater in ulcerative colitis than Crohn's disease (p less than 0.01) or cystic fibrosis (p less than 0.01). The lifetime prevalence of atypical depression was significantly greater in Crohn's disease than cystic fibrosis (22% versus 5.8%, p less than 0.05) and was also greater in ulcerative colitis than cystic fibrosis (21% versus 5.8%, p = 0.1). There was no difference between the groups in the current prevalence of major depression or atypical depression, or in the lifetime or current prevalence of anxiety disorders.

Although a familial component to schizophrenia has been established through several family, twin and adoption studies, an inherited biological factor has yet to be established. Efforts to define clinical familial subtypes of schizophrenia have generally been unsuccessful, although recent data from our study population of pairs of siblings with schizophrenia suggests that schizophrenia with recurrent episodes of major depression may define one such group. There have only been a few biological traits consistently found to be associated with schizophrenia and also found to be heritable. These findings (e.g. measures of monoamine metabolism, brain structural morphology, neurophysiological markers, and protein polymorphisms) are reviewed in the present chapter. The proportion of patients with any of the noted abnormalities never approaches 100%, nor have any been found to be specific to schizophrenia. Research into the biogenetics of schizophrenia is clearly just beginning.

This paper has examined the possibilities of applying significant pharmacologic help to a variety of psychiatric problems that may accompany narcotic addiction. It has been shown that many of the patients do have such difficulties, with affective disorders being most common. As far as the various psychotropic drugs are concerned, neuroleptics for schizophrenia and lithium for manic disorders are generally agreed upon. A more extensive trial of lithium in a variety of situations seems indicated. Minor tranquilizers for anxiety and MAO-inhibitors for depression are both seen as problematic in this population--the former because of the possibility of abuse, the latter because of the danger of drug interaction associated with the addict's careless lifestyle. Tricyclic antidepressants may clearly have a role in treating major depression in opiate addicts on or off methadone, but the lability of the syndrome over time with frequent spontaneous remission argues against their routine use until it is clear that depression has persisted 3-6 months into methadone. Disulfiram appears to be a useful adjunct for drug abusers with serious alcohol problems. Psychotropic agents are most helpful to opiate addicts when used to treat coexisting psychopathology. While there is no clear evidence that such agents will reduce or affect the addiction itself, they may help keep patients available for rehabilitation efforts. Failure to intervene may make treatment dropout and recidivism more likely. Given the relative frequency of potentially treatable psychiatric disorders in these patients and the consequences of undiagnosed and untreated conditions, it is important for clinicians to maintain a high index of suspicion for concomitant psychiatric illness and for programs to have a mechanism for routinely diagnosing either all patients or, at a minimum, all patients not doing well. If programs used a standard instrument such as the SADS, it would be possible to compare various programs on this factor; in addition, it would provide a rich source of data for outcome studies.
