A meta-analysis of controlled studies on prevalence of eating disorders in Type 1 diabetes was performed in order to assess differences between diabetic and non-diabetic female subjects. All controlled studies using the Diagnostic and Statistical Manual of Mental Disorders Third Edition Revised (DSM III-R) or the DSM Fourth Edition (DSM IV) criteria for interview-based diagnosis were included in the analysis. The total sample was composed of 748 and 1587 female subjects with and without diabetes, respectively. The prevalence of anorexia nervosa (AN) in Type 1 diabetic subjects was not significantly different from that of controls (0.27 vs 0.06%), while that of bulimia nervosa and of the two conditions combined was significantly higher in diabetic patients (1.73 vs 0.69%, and 2.00 vs 0.75%, respectively; both p<0.05). Type 1 diabetes is associated with a higher prevalence of bulimia nervosa in females.

Various studies have evaluated the possible role of the −1438G/A polymorphism within the 5-HT2A receptor gene in the susceptibility to Eating Disorders (EDs). One hundred and forty-eight ED patients (EDp) and 89 control subjects were interviewed by means of the Eating Disorder Examination (EDE) and analyzed for distribution of the −1438G/A polymorphism. Patients with the AA genotype suffering from Anorexia Nervosa and Bulimia Nervosa showed higher Weight and Shape Concern (P=0.003 and P=0.010, respectively) scores and greater overall severity of the ED psychopathology (EDE total score) (P=0.012). The obtained preliminary data suggest the use of dimensional psychopathological measures in ED genetic studies.

The prevalence and the clinical meaning of cannabis use in patients with chronic psychosis has not been systematically explored. The authors have compared the diagnostic and symptomatological characteristics of 111 male patients affected by chronic psychosis with and without past or current use of cannabis. Sixty-six patients were still using or had used cannabis; in all cases the use preceded the onset of psychotic symptoms. Forty-three patients were cannabis-positive on urinary screening at the moment of hospitalization and 23 were currently cannabis-free but reported the use of cannabis in the past. Forty-five patients were negative on urinary screening and reported no past history of cannabis use. In evaluating the psychopathological features, the Brief Psychiatric Rating Scale (BPRS) and the Overt Aggression Rating Scale (AORS) were used. The three groups showed similar demographic data, except for age, which was lower in current cannabis users than in nonusers; no differences were found between current and past users. As regards diagnostic features, "mood cluster" was significantly better represented in cannabis users and "schizophrenic cluster" in nonusers; bipolar spectrum disorders were more frequently reported than unipolar ones. When past and current users were grouped together, only blunted affect score was significantly higher in nonusers than in users, while clastic violence showed higher scores in users. These data indicate that chronic psychosis, whether associated with past or with current use of cannabis, is frequently associated with bipolar spectrum disorders and tends to display less blunted affect and more clastic behavior.

Background: In this study, we investigate the affective temperamental characteristics in a sample of ED (eating disorder) patients. Methods: 49 ED patients diagnosed by the SCID (Structured Clinical Interview for DSM-IV), were divided into two groups on the basis of the presence or absence of Binge Eating (restricting-anorexia nervosa [R-AN]= 16; Binge Eaters= 33). All patients were administered the TEMPS-I (Temperament Evaluation Memphis Pisa Semistructured — Interview), to assess affective temperament. A third group of controls (N= 1010), derived from a study with the TEMPS-I on normal subjects, was included for comparison. Results: A full affective temperament was not found in patients of the restricting group. By contrast 24% of the binge eating group had a full affective temperament of one of three types. Comparing the three temperaments for the three groups, only cyclothymic temperament proved to be significant, with higher levels in the binge eating group (p<0.01). Conclusions: In this study, people with R-AN do not show a full affective temperament. However, people with binge eating, had depressive and hyperthymic temperament, and displayed higher level of cyclothymic temperament than the normal population. The findings of this study add to a growing literature on temperament in people with ED; particularly, they add to the view that may be various paths leading to R-AN, and these may differ from those of binge eating.

Objective: Aim of this study was the assessment of the prevalence of eating disorders, and of eating disorder symptoms, in obese patients with type 2 diabetes, compared to non-diabetic subjects. Design: Three samples of individuals were studied: a series of 156 (76 male, 80 female) overweight and obese type 2 diabetic patients, aged 30–65 y, with a body mass index (BMI)>28 kg/m 2 (DM); a series of 192 (20 male, 172 female) obese (BMI>30 kg/m 2 ) non-diabetic patients aged 30–65 y seeking treatment for weight loss (OC); and a non-clinical sample of 48 (22 male, 26 female) obese (BMI>30 kg/m 2 ) subjects aged 30–65 y selected from the lists of two general practices (OP). Eating behavior was assessed using the Eating Disorder Examination (EDE 12.0D). Results: The prevalence of Binge Eating Disorder was lower than 5% in all the three samples. Median EDE scores in females were significantly higher in OC (3.0) and OP (3.4) than in DM (1.7), while diabetic patients showed higher scores on Restraint than both non-diabetic samples. Among diabetic patients, a significant correlation of EDE scores with HbA 1 c was observed. Conclusions: Type 2 diabetes is unlikely to induce relevant eating disturbances in obese patients, apart from an increase in restraint. Abnormalities of eating attitudes and behavior are associated with an impairment of metabolic control.

Although obsessive-compulsive disorder (OCD) has been found to be the 10th leading cause of disability of all medical conditions in the industrialized world, comparatively little is known about psychosocial functioning and quality of life (QOL) in OCD, particularly with regard to their relationship with symptom severity.Quality of life and psychosocial function of 197 adults were assessed as part of a larger intake interview for a 5-year prospective study of OCD course. Two self-report measures (the Quality of Life Enjoyment and the Medical Outcomes Survey 36-Item Short-Form Health Survey) and 2 clinician-rated measures (the Range of Impaired Functioning Tool and the Social and Occupational Functioning Assessment Scale), each with established reliability and validity, were administered. Symptom severity was assessed with the Yale-Brown Obsessive-Compulsive Scale (YBOCS).Quality of life was significantly impaired compared with published community norms with large effect sizes found for all domains assessed. The correlations (r) between all QOL measures and the YBOCS total score were significant, ranging from 0.40 to 0.77. Correlations between the YBOCS obsessions subscore and QOL measures were higher than those found between the YBOCS compulsions subscore and QOL. Insight as measured by the Brown Assessment of Beliefs Scale was significantly correlated with 5 of the 7 measures, although more modestly than the YBOCS correlations (r = 0.22 to 0.37). Subjects with a YBOCS score of 20 or higher had significant decline in QOL compared with those subjects with YBOCS scores lower than 20. Severity of obsessions and depressive symptoms, as well as marital status, were significant predictors of impairment in QOL.These findings indicate that all aspects of QOL are markedly affected in individuals with OCD and are associated with OCD severity (particularly obsessional severity) and depression severity. Exploratory results suggest that QOL and psychosocial functioning begins to be more significantly affected at YBOCS scores higher than 20. This score might be considered as a threshold criterion for OCD for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition.

Dysthymia, as defined in the American Psychiatric Association and International Classification of Mental Disorders, refers to a prevalent form of subthreshold depressive pathology with gloominess, anhedonia, low drive and energy, low self-esteem and pessimistic outlook. Although comorbidity with panic, social phobic, and alcohol use disorders has been described, the most significant association is with major depressive episodes. Family history is loaded with affective, including bipolar, disorders. The latter finding explains why dysthymia, especially when onset is in childhood, can lead to hypomanic switches, both spontaneously and upon pharmacologic challenge in as many as 30%. Indeed, antidepressants from different classes -tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), reversible inhibitors of monoamine oxidase A (RIMAs), selective serotonin-reuptake inhibitors (SSRIs) and, more recently, amisulpride, and spanning noradrenergic, serotonergic as well as dopaminergic mechanisms of action - have been shown to be effective against dysthymia in an average of 65% of cases. This is a promising development because social and characterologic disturbances so pervasive in dysthymia often, though not always, recede with continued pharmacotherapy beyond acute treatment. Despite symptomatic overlap of dysthymia with chronic fatigue syndrome - especially with respect to the cluster of symptoms consisting of low drive, lethargy, lassitude and poor concentration - neither the psychopathologic status, nor the pharmacologic response profile of the latter syndrome is presently understood. Chronic fatigue today is where dysthymia was two decades ago. We submit that the basic science - clinical paradigm that has proven so successful in dysthymia could, before too long, crack down the conundrum of chronic fatigue as well. At a more practical level, we raise the possibility that a subgroup within the chronic fatigue group represents a variant of dysthymia.

Objective: It is generally accepted that temperament is not entirely stable, and that it changes with development, particularly in juvenile subjects also, some temperaments are believed to be inherently more unstable. There is a great deal of current interest in Kraepelin a thesis that temperamental dysregulation in juvenile subjects represents the constitutional foundation from which the more florid episodes of manic-depressive illness arise; the cyclothymic, hyperthymic, depressive and irritable temperaments under consideration might represent the first observable phenotypes of the genetic diathesis for bipolarity. The analyses on the temperamental attributes in juvenile subjects were undertaken within this theoretical framework. Method: We evaluated 206 Italian high school students (14-18 years old) by means of a semi-structured affective temperament interview (TEMPS-I) at TO and TI two years later. Age, sex and psychometric properties of TEMPS-I raw scale score and weighted cut-off las specially weighted linear combination of items) were used as predictive variables of stability. Results: Affective temperaments had a low to moderate level of stability, reaching 60% in the case of subjects with dominant cyclothymic temperament. The stability of the depressive temperament was primarily related to its weighted cut-off. The stability of the hyperthymic temperament appeared related to male sex, young age, and total scale score. Male sex represented the best stability predictor for the cyclothymic temperament as well. The group of subjects with an unstable depressive temperament showed a change toward the dominant cyclothymic temperament, whereas individuals with unstable hyperthymic temperamental traits moved on towards the dominant cyclothymic and depressive temperaments. The irritable construct was the least stable. Limitations: The infeasibility of a multiwave design represents the main limitation in evaluating the predictors of stability. Furthermore, in the present analyses, the size of the cyclothymic subsample was small. Conclusion: Our data indicate considerable fluctuation and instability in depressive and hyperthymic temperaments in mid-adolescence. The cyclothymic temperament appears to be the most stable. Interestingly, cyclothymic moodiness appears more persistent in juvenile males; likewise persistent hyperthymic traits appear more of a "male" attribute. Clinical and Public Health Implications: We submit that these sex-relevant traits could be important in the risk of developing juvenile bipolarity. Literature review indicates that clinical studies, albeit on small samples, have already provided some support for this thesis. Larger studies on epidemiological samples could be more informative from a public health perspective. A user-friendly affective temperament questionnaire, which is under development, is critical for the methodology of such studies. Our study indicates that the present version of the Akiskal-Malya questionnaire can be easily used post-pubertally. Age adjustment must be considered for younger subjects.

BACKGROUND:Although most personality constructs have been standardized in population studies, cyclothymic, depressive, irritable and hyperthymic temperaments putatively linked to mood disorders have been classically derived from clinical observations. METHODS:We therefore administered the semi-structured affective temperament schedule of Memphis, Pisa, Paris and San Diego, Interview version (TEMPS-I) -- in its original University of Tennessee operationalization -- to 1010 Italian students aged between 14 and 26. The interview, administered in a randomized format, took 20 min per subject. RESULTS:The semi-structured interview was easy to administer and well accepted by subjects, with no refusals. Principal component analysis with varimax rotation confirmed the hypothesized four-dimensional factor structure of the interview, with good to excellent internal consistency. Furthermore, discriminant analysis and multiple regression provided suggestions for identifying the traits that are most useful in defining a weighted cut-off for each of the temperaments (and which, with minor exceptions, are in agreement with those previously proposed on clinical grounds). In an additional exploratory factorial analysis, a depressive type which loads negatively on hyperthymia was distinguished from cyclothymia; the irritable temperament did not appear to have significant loading on either factor. LIMITATION:All the present analyses were internal to the scale itself, but ongoing studies are comparing them with other systems of temperament as well as testing their clinical cogency for affectively ill populations. CONCLUSION:While more work needs to be done on better operationalization of the irritable temperament, our findings overall support the existence -- in a relatively young nonpatient population -- of cyclothymic, depressive and hyperthymic types according to the classic descriptions of Kraepelin, Kretschmer and Schneider, in their TEMPS-I operationalization. CLINICAL IMPLICATIONS:Coupled with a previous report identifying 10% of the same 14-26-year-old nonpatient population meeting an empirically defined statistical cut-off for these temperaments, the present data define the putative 'fundamental states' that Kraepelin considered to be the personal predisposing anlagé of major affective disorders.

A role of psychic stress in precipitating hyperthyroid Graves’ disease has been suggested, but the evidence in support of this pathogenetic mechanism is conflicting. In this study we investigated the possible occurrence of Graves’ disease in patients with panic disorder, a psychiatric condition characterized by recurrent endogenous stress. The study group included 87 consecutive patients suffering from panic disorder since 1 to 30 years: 17 males (mean age 31.3, range 26–43 years) and 70 females (mean age 37.6, range 15–73 years). Two hundred and sixty-two normal subjects with no present or past history of psychiatric disorder served as controls. Patients were submitted to a full evaluation of the thyroid that included physical examination, assays for free thyroid hormones, TSH, thyroglobulin (TgAb), thyroperoxidase (TPOAb) and TSH receptor (TRAb) antibodies, and thyroid echography. The prevalence of circulating TgAb and/or TPOAb in patients with panic disorder did not differ from that in the control group. Twelve patients with panic disorder (13.7%) had circulating TgAb and/or TPOAb, but none had TRAb. Three out of 12 patients with thyroid antibodies, indicating a genetic susceptibility to autoimmune thyroid disease, had a family history of clinical thyroid autoimmunity, and 4 of them had a hypoechogenic pattern of the thyroid at ultrasound suggesting autoimmune thyroiditis. None of the patients with panic disorder had a previous history of hyperthyroidism. On examination, clinical hyperthyroidism or endocrine ophthalmopathy were not found in any of them. A small goiter was appreciated by palpation in 16 patients (18.3%). Free thyroid hormones and TSH were within the normal range in all patients but one: a 55-year old lady with normal serum free thyroid hormones and undetectable TSH. During an 18-month follow-up she did not develop hyperthyroidism and her TSH spontaneously returned in the normal range. Considering the individual duration of panic disorder, evidence for previous or present Graves’ hyperthyroidism was not found for a total of 478 patient-years of exposure to recurrent endogenous stress in the whole study group, and for a total of 39 patient-years in patients with a genetic susceptibility to autoimmune thyroid disease. In conclusion, we found that recurrent endogenous stress did not precipitate Graves’ hyperthyroidism in a series of 87 patients with panic disorder, encompassing a total of 478 patient-years of exposure to stress. Failure to activate the hypothalamic-pituitary-adrenal axis by endogenous stress due to panic disorder as opposed to exogenous stress due to life-events might explain why panic disorder does not precipitate Graves’ hyperthyroidism.

BACKGROUND:The purpose of this study was to evaluate the reliability and psychometric properties of the Semistructured Affective Temperament Interview, and determine cut-offs for each temperament.METHOD:1010 Italian students aged between 14 and 26 were evaluated by means of the Akiskal and Mallya criteria in a Semistructured Interview for depressive, cyclothymic, hyperthymic, and irritable temperaments.RESULTS:This instrument has very good reliability and internal consistency. The percentage of subjects with a z-score higher than the second positive standard deviation ( + 2 SD) on the scales of depressive and cyclothymic temperaments are 3.6% and 6.3% (reaching scores of 7/7 and 9/10), respectively. Hyperthymic traits, on the other hand, are widespread in our sample: most subjects are included within the second positive standard deviation ( + 2 SD), and 8.2% of these reach a 7/7 score; therefore, the problem of defining a cut-off for this temperament is still open. By contrast, the irritable temperament is rare, conforming to a non-gaussian distribution, with 2.2% of cases above the second positive standard deviation ( + 2 SD).LIMITATION:The data are based on subject report without collateral information and external validation.CONCLUSION:This study contributes to more accurate definition of cut-offs for individual temperament scales. The standardization of the interview thus makes it possible to compare three out of four temperamental scales, showing the dominant temperamental characteristics for each subject. Prospective studies are needed to demonstrate the stability of these traits over time.

A group of 33 sportsmen and 43 sportswomen and a group of 488 subjects (less than 30 years old) selected from a sample of 816 subjects representative of the general Italian population were compared using the factor scores and total scores on the Italian version of the Buss and Durkee questionnaire. Analysis suggests a positive correlation between aggressiveness and sport and are compatible with the hypothesis that sporting activities serve as a means of controlling aggressiveness of women and help the individual psychosocial development of men. The decision to practice sports would seem to be connected with the needs to conform to cultural stereotypes, which portray the man as aggressive and the woman as gentle and submissive.

It has been generally agreed that mood disturbances are quite common in patients with thyroid dysfunctions. Depressive symptoms are very frequent in hypothyroid patients although manic episodes may be occasionally observed. On the other hand, it has been reported that depressive patients may show some clinical symptoms of hypothyroidism (Gold et al. 1981; McGaffe et al. 1981); treatment with thyroid hormones may have beneficial effects on these patients.

In the late 1960s interest in the clinical activity of rubidium was stimulated by the reports of Meltzer and coworkers (Meltzer et al. 1973; Meltzer and Fieve 1975; Fieve 1976; Fieve and Meltzer 1974a, b; Fieve et al. 1973). Since then various open and a few controlled studies have been published on the antidepressant efficacy of this compound (Calandra and Nicolosi 1980; Casacchia et al. 1984; Corsini et al. 1984; Belmaker et al. 1984; Geisler et al. 1984; Sarteschi et al. 1984; Vampini and Robotti 1985).
