Of 510 patients consecutively admitted and diagnosed as schizophrenic, 310 who failed to meet research criteria for schizophrenia were labelled as having ‘atypical psychosis'. This heterogeneous group of patients was then subtyped into more homogeneous subgroupings according to their clinical characteristics, independent of their family data. One subgroup resembled schizophrenia, one resembled affective disorders and a third (n = 57), which did not resemble either schizophrenia or affective disorder, was defined as ‘schizoaffective’. Comparing the morbidity risks for schizophrenic and affective disorders in the relatives of this schizoaffective group with those of the relatives of ‘typical’ groups of schizophrenia and affective disorder, showed that this group was different from those with schizophrenic and affective disorders.

SummaryOne thousand five hundred and seventy eight first degree relatives of schizophrenics, manics, depressives and controls were personally interviewed using the Iowa Structured Psychiatric Interview Form without knowledge of the probands' diagnoses. Our data, based on blind diagnostic assessment of the relatives, support the distinction between schizophrenia and affective disorders, although the distinction between schizophrenia and mania was not clear-cut. Our data could not support familial subtyping of paranoid and non-paranoid schizophrenia, and unipolar and bipolar affective disorders. Future studies attempting to develop research criteria for subtyping schizophrenia and affective disorders should utilize not only clinical and familial data but also biological markers and other non-familial variables.

A family study was carried out in two groups of patients fulfilling RDC for schizoaffective disorder: in one, a full affective and a full schizophrenic syndrome were simultaneously present; in the other, affective and schizophrenic features appeared within a polymorphic and rapidly changing clinical picture, with depersonalisation/derealisation and/or confusion. In the first-degree relatives of patients of the former group, the risk of major psychiatric disorders was not significantly different from that of relatives of schizophrenics, whereas in the first-degree relatives of patients of the latter group a low risk for both schizophrenia and major affective disorders, and a relatively high risk for schizoaffective disorders, were observed.

OBJECTIVEIn the past decade, a gradual transition of health policy to value-based healthcare has brought increased attention to measuring the quality of care delivered. In spine surgery, adolescents with scoliosis are a population particularly at risk for depression, anxious feelings, and impaired quality of life related to back pain and cosmetic appearance of the deformity. With the rising prevalence of mental health ailments, it is necessary to evaluate the impact of concurrent affective disorders on patient care after spinal surgery in adolescents. The aim of this study was to investigate the impact that affective disorders have on perioperative complication rates, length of stay (LOS), and total costs in adolescents undergoing elective posterior spinal fusion (PSF) (≥ 4 levels) for idiopathic scoliosis.METHODSA retrospective study of the Kids’ Inpatient Database for the year 2012 was performed. Adolescent patients (age range 10–17 years old) with AIS undergoing elective PSF (≥ 4 levels) were selected using the International Classification of Diseases, Ninth Revision, Clinical Modification coding system. Patients were categorized into 2 groups at discharge: affective disorder or no affective disorder. Patient demographics, comorbidities, complications, LOS, discharge disposition, and total cost were assessed. The primary outcomes were perioperative complication rates, LOS, total cost, and discharge dispositions.RESULTSThere were 3759 adolescents included in this study, of whom 164 (4.4%) were identified with an affective disorder (no affective disorder: n = 3595). Adolescents with affective disorders were significantly older than adolescents with no affective disorders (affective disorder: 14.4 ± 1.9 years vs no affective disorder: 13.9 ± 1.8 years, p = 0.001), and had significantly different proportions of race (p = 0.005). Aside from hospital region (p = 0.016), no other patient- or hospital-level factors differed between the cohorts. Patient comorbidities did not differ significantly between cohorts. The number of vertebral levels involved was similar between the cohorts, with the majority of patients having 9 or more levels involved (affective disorder: 76.8% vs no affective disorder: 79.5%, p = 0.403). Postoperative complications were similar between the cohorts, with no significant difference in the proportion of patients experiencing a postoperative complication (p = 0.079) or number of complications (p = 0.124). The mean length of stay and mean total cost were similar between the cohorts. Moreover, the routine and nonroutine discharge dispositions were also similar between the cohorts, with the majority of patients having routine discharges (affective disorder: 93.9% vs no affective disorder: 94.9%, p = 0.591).CONCLUSIONSThis study suggests that affective disorders may not have a significant impact on surgical outcomes in adolescent patients undergoing surgery for scoliosis in comparison with adults. Further studies are necessary to elucidate how affective disorders affect adolescent patients with idiopathic scoliosis, which may improve provider approach in managing these patients perioperatively and at follow-up in hopes to better the overall patient satisfaction and quality of care delivered.

Fifty outpatients in a ‘schizophrenia clinic’ were examined, and sixteen were found to be suffering from periodic affective disorders. Nine of these were given lithium carbonate, and eight responded well. Case histories illustrate three separate reasons for incorrect diagnosis. Examination of extensive old clinical notes of five of these patients suggests that the problems of diagnosis which have been described in the literature in the past, continue to represent obstacles to correct diagnosis. Suggestions for improvement are offered.

Twin data on bipolar and unipolar affective disorders are analyzed by multiple threshold models of inheritance. The two illness types are represented in the models on a continuum of genetic–environmental liability in which bipolar illness has a higher liability threshold than unipolar disorder. Autosomal single major locus model provides an acceptable fit to observed concordance rates in monozygotic twins. The multifactorial-polygenic model is rejected.

For the use of the term “affective disorder” there is good literary warrant. Shakespeare, writing in the last decade of the sixteenth century, or just before it, uses the word thus:“Necessity will make us all forswornThree thousand times within this three years' space;For every man with his affects is born,Not by might mastered, but by special grace” (92).

Advances towards the understanding of the etiological mechanisms involved in mood disorders provide interesting yet diverse hypotheses and promising models. In this context, molecular genetics has now been widely incorporated into genetic epidemiological research in psychiatry. Affective disorders and, in particular, bipolar affective disorder (BPAD) have been examined in many molecular genetic studies which have covered a large part of the genome, specific hypotheses such as mutations have also been studied. Most recent studies indicate that several chromosomal regions may be involved in the aetiology of BPAD. Other studies have reported the presence of anticipation in BPAD and in unipolar affective disorder (UPAD). In parallel to these new developments in molecular genetics, the classical genetic epidemiology, represented by twin, adoption and family studies, provided additional evidence in favour of the genetic hypothesis in mood disorders. Moreover, these methods have been improved through models to test the gene-environment interactions. In addition to genetic approaches, psychiatric research has focused on the role of psychosocial factors in the emergence of mood disorders. In this approach, psychosocial factors refer to the patient's social life context as well as to personality dimensions. Abnormalities in the social behavior such as impairment in social relationships have been observed during episode of affective disorders, and implicated in the etiology of affective disorders. Further, gender and socio-economic status also emerged as having a possible impact on the development of affective disorders. Finally, the onset and outcome of affective disorders could also be explained by interactions between the social life context and the individual's temperament and personality. The importance of temperament and personality characteristics in the etiology of depression has been emphasized in various theories, although disagreement exists with regard to terminology and the etiology. While significant advances have been done in these two major fields of research, it appears that integrative models, taking into account the interactions between biological (genetic) factors and social (psychosocial environment) variables offer the most reliable way to approach the complex mechanisms involved in the etiology and outcome of mood disorders. This chapter will review some of the most promising genetic and psychosocial hypotheses in mood disorders that can be integrated in interactive models.

SummaryPatients receiving prophylactic lithium therapy for primary affective disorder during a four year period were studied for recurrence of affective illness. Patients who had affective episodes during this period did not differ from those who remained well in age, sex or diagnosis. Those with a favourable outcome had spent significantly less time at serum lithium levels above 0.9 mmol/litre than those who had a recurrence of affective episodes.
