Dysthymic disorder: clinical characteristics in relation to age at onset.

BACKGROUND: The variability in the clinical presentation of dysthymia has given rise to a rich debate in literature, and various hypotheses have been proposed. One is that the clinical presentation differs in relation to age at onset. The aim of the study was to evaluate differences in socio-demographic and clinical characteristics in a sample of patients with dysthymia (DSM-IV), in relation to age at onset. METHOD: 84 consecutive outpatients with a diagnosis of dysthymia (DSM-IV) were studied. All subjects were evaluated by a semistructured clinical interview and the following rating scales: HAM-A, HAM-D, MADRS, Paykel's Interview for Recent Life Events. RESULTS: 23.8% of the sample had early-onset (<21 yrs) dysthymia. Patients with early-onset disorder were significantly younger at the observation, more frequently female and single. They had a significantly longer duration of illness and in a significantly higher percentage had already received a specialist treatment before admission in the present trial. No differences in the frequency of symptoms were observed. A significantly higher percentage of patients with late-onset disease reported at least one stressful event in the year preceding the onset of dysthymia. A positive history of major depression was significantly more common among the early-onset group; social phobia, panic disorder and conversive disorder were also more frequent in this group. The late-onset patients frequently presented generalized anxiety disorder, substance abuse and somatization disorder. LIMITATION: The study is retrospective and enrolls a limited number of cases. CONCLUSIONS: The present study agrees with other reports on the differences in clinical presentation of dysthymia according to age at onset. Although they are not actually related to age at onset, some interesting findings emerged in the symptomatological characterization of the disorder, referring to the diagnostic criteria proposed in DSM-IV.

Gender-related distribution of personality disorders in a sample of patients with panic disorder.

OBJECTIVE: We examined gender differences in the frequency of DSM-IV personality disorder diagnoses in a sample of patients with a diagnosis of panic disorder (PD). METHOD: One hundred and eighty-four outpatients with a principal diagnosis of PD (DSM-IV) were enrolled. All patients were evaluated with a semi-structured interview to collect demographic and clinical data and to generate Axis I and Axis II diagnoses in accordance with DSM-IV criteria. RESULTS: Males were significantly more likely than females to meet diagnoses for schizoid and borderline personality disorder. Compared to males, females predominated in histrionic and cluster C diagnoses, particularly dependent personality disorder diagnoses. A significant interaction was found between female sex and agoraphobia on personality disorder (PD) distribution. CONCLUSIONS: Male PD patients seem to be characterized by more severe personality disorders, while female PD patients, particularly with co-morbid agoraphobia, have higher co-morbidity rates with personality disorders belonging to the 'anxious-fearful cluster'.

Gender-related differences in the onset of panic disorder.

OBJECTIVE: To investigate gender-related differences in premorbid conditions and in the role of triggering events in the onset of panic disorder (PD). METHOD: One hundred and eighty-four out-patients with a principal diagnosis of PD (DSM-IV) were evaluated with a semi-structured interview to generate Axis I and Axis II diagnoses according to DSM-IV, to collect family history of psychiatric disorders and life events. The statistical analysis was performed comparing men and women. RESULTS: Men and women showed similar age at onset of PD. A family history of mood disorders characterized females. Men had higher rates of cyclothymia, body dysmorphic disorder and depersonalization disorder preceding PD, while women had higher rates of bulimia nervosa. Dependent and histrionic PDs were more common among women, while borderline and schizoid PDs were more common among men. Life events showed a significant role in precipitating PD onset in women. CONCLUSION: Premorbid clinical conditions of PD seem to differentiate between males and females in the role of precipitating events.

Therapeutic effect and safety of adjunctive risperidone in refractory obsessive-compulsive disorder (OCD).

It has been well established that more than 40 percent of patients with obsessive-compulsive disorder (OCD) do not improve after an adequate trial with serotonin uptake inhibitors (SUIs). The first purpose of this trial was to compare the short-term efficacy and safety of two different strategies in a sample of treatment-refractory OCD patients: dose increase of the ongoing treatment versus the addition of another SUI. The second purpose was to investigate the short-term efficacy and safety of adjunctive risperidone in SUI-refractory OCD patients. Thirty-three OCD patients who were unimproved after a short-term treatment with clomipramine (150 mg/day) were admitted to the study. In the first part of the study, the dose increase of clomipramine was compared with sertraline addition, in an open-label manner. The addition of sertraline to the ongoing treatment appeared to be more effective and tolerable than the clomipramine dose increase. Seven (50%) of the 14 patients who were considered nonresponders after the first part of the study, showed good clinical improvement and good tolerability after risperidone augmentation. These results suggest that risperidone addition to ongoing SUIs may be useful in augmenting pharmacologic response in OCD.

Drug treatment of obsessive-compulsive disorder (OCD): long-term trial with clomipramine and selective serotonin reuptake inhibitors (SSRIs).

A 2-year, open-label followup was performed on 130 obsessive-compulsive patients who were responders to a previous 6-month treatment with clomipramine (150 mg/day), fluoxetine (40 mg/day), or fluvoxamine (300 mg/day). Continuation treatment with the same daily dose was compared to continuation with half doses or to discontinuation of pharmacotherapy. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Clinical Global Impressions (CGI) scale were used every 3 months, or whenever a worsening of symptoms was experienced. Maintenance treatments were found significantly superior to discontinuation in preventing relapses, and no differences in efficacy were found between full and half doses. A comparison of the three subgroups of patients who were withdrawn from drug therapy failed to demonstrate any statistical difference.

[Stress, depression and anxiety in patients with headache. Considerations of literature and experimental data]. / Stress, depressione e ansia in pazienti cefalalgici. Considerazioni sulla letteratura e dati sperimentali.

After having examined the main studies which suggest the existence of correlations between anxiety, depression and cephalagia, the authors report the results of a study performed in a sample population of some three hundred subjects. During the presentation and discussion of results they also comment on some of the main psychodynamic theories relating to the etiology of idiopathic cephalea. In particular, they examine the theories which relate the onset of cephalea to the inhibition of thought and those which instead connect the onset of cephalea to aggressiveness. The present study also comments on possible interpretative models along Individual-psychology lines concerning stress-related somatisation.

Predictors of drug treatment response in obsessive-compulsive disorder.

BACKGROUND: Although a large body of evidence indicates the efficacy of pharmacotherapy in the treatment of obsessive-compulsive disorder (OCD), a considerable percentage of these patients do not respond. Very few studies focus on factors related to treatment response of OCD. The purpose of this study was to investigate which clinical factors are related to drug treatment response in OCD. METHOD: We examined 53 OCD patients treated with either clomipramine or fluoxetine for a period of 6 months, dividing the sample into "responders" and "nonresponders" to treatment. At admission, patients were evaluated using a semistructured clinical interview, the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Hamilton Rating Scale for Depression, and the Hamilton Rating Scale for Anxiety. We then compared acute-phase patient characteristics and response to drug treatment. Response was defined as a decrease of at least 40% in the Y-BOCS total score and a rating of "improved" or "very improved" on the Clinical Global Impressions scale within 16 weeks of treatment and maintained over three consecutive evaluations. RESULTS: By the sixth month of treatment, 31 patients (58.5%) responded to either clomipramine or fluoxetine. Nonresponders had lower age at onset and longer duration of the disorder; in addition, they showed higher frequency of compulsions, washing rituals, chronic course, concomitant schizotypal personality disorder, and previous hospitalizations. A worse response to drug treatment was predicted in a stepwise multiple regression by (1) concomitant schizotypal personality disorder, (2) presence of compulsions, and (3) longer illness length. CONCLUSION: Our findings suggest that there are distinct types of OCD with respect to drug treatment response. They provide indirect evidence of treatment specificity by identifying characteristics responsive to different modalities, which may be of value in the selection of patients for alternative treatments.

Type I and type II schizophrenia: relations between tonic electrodermal activity and clinical ratings before and after haloperidol treatment.

To test the hypothesis that schizophrenic patients with positive vs. negative symptoms show different tonic electrodermal patterns, 26 patients with Type I schizophrenia and 19 patients with Type II schizophrenia were evaluated before and after 2 weeks of haloperidol treatment (standard daily dose = 4.5 mg). Clinical assessments were made with the Brief Psychiatric Rating Scale, the Scale for the Assessment of Positive Symptoms, and the Scale for the Assessment of Negative Symptoms. Skin conductance level (SCL) and spontaneous fluctuations (SF) frequency were recorded for each patient. Before treatment, Type I patients showed higher SCL and SF compared with Type II patients; after treatment, a significative decrease of clinical and psychophysiological variables was found only in Type I patients.

[Comments relating to the psychosexual characteristics of the male transsexual. A clinical study]. / Alcune considerazioni relative alle caratteristiche psicosessuologiche del transessuale maschio. Una ricerca clinica.

In this paper the authors analyse transexualism from a psychopathological, nosographic and clinical point of view. The re-examine the theories on the subjects elaborated by a number of authors and describe the clinical characteristics of the syndrome, paying special attention to problems relating to differential diagnosis. Moreover, they present the results ofa study carried out in a personal series of cases. The sample studied included 11 male transsexual subjects. The latter were evaluated through psychiatric interview and a questionnaire aimed at obtaining information on the following topics: the subjects' social and affective relations; their childhood experience; their perception and acceptance of themselves; the meaning, characteristics, localisation and experience of sexual pleasure. The results are discussed and compared with those of national and international literature on this subjects.
