Incidence of obsessive-compulsive phenomena in the course of acute schizophrenia and schizoaffective disorder.

Studies examining OC phenomena in schizophrenic and schizoaffective disorders have shown a prevalence of such phenomena in 1 to 60% of schizophrenic or schizoaffective patients. In this prospective study, about 10% of 150 male patients suffering from acute psychotic disorders (fulfilling DSM-IV criteria for Schizophrenia or Schizoaffective Disorder) were found to have OC symptoms. These symptoms showed no correlation to the type and severity of psychosis. As only 19% of the patients with obsessions and compulsions during acute psychosis showed an obsessive-compulsive personality disorder prior to their psychotic episodes, it may be concluded that there is no clear linkage between intrapsychotic OC phenomena and premorbid anancastic personality traits.

Basic symptoms and their contribution to the differential typology of acute schizophrenic and schizoaffective disorders.

One hundred and fifty male inpatients - 128 patients with DSM-IV schizophrenia and 22 patients with DSM-IV schizoaffective disorder - were investigated, over the course of their acute psychosis, on whether there were differences in the extent of basic symptoms (measured by the Bonn Scale for the Assessment of Basic Symptoms) according to their diagnostic subtype. Another aim was to find out if the diagnostic subtypes could be discriminated by means of basic symptoms and if clusters gained from basic symptoms were in accordance with the diagnostic subtypes. Differences in basic symptoms were found between the subtypes, but a clear discrimination of diagnostic subtypes by means of basic symptoms could not be achieved. There was indication that patients with prominent delusions or auditory hallucinations reported more basic symptoms than patients with exclusively prominent disorganization.

A case of comorbidity between panic disorder and photosensitive epilepsy.

Panic disorder and epilepsy usually are distinct entities which require different and specific therapeutic strategies. While anticonvulsant medication is the treatment of choice for seizure disorders, behavioral methods have proven to be effective in panic disorder. We here report a case of comorbidity between panic disorder and photosensitive epilepsy. Special attention is given to the different symptomatic presentations of the disorders, because a thorough knowledge of both disorders may save unnecessary diagnostic procedures. Therefore, the necessity of taking a careful patient's history is underlined. Furthermore the different possible relationship between panic disorder and epilepsy are discussed.

The development of agoraphobia in panic disorder: a predictable process?

BACKGROUND: Panic attacks are conceptualized to be the central feature of both panic disorder without (PDU) and with agoraphobia (PDA). As a sizeable percentage of panic patients do not develop avoidance behavior, other factors than 'panic attacks', in general, must influence the different courses of the disorder. METHOD: We studied 84 outpatients suffering from PDU or PDA concerning different factors which were hypothesized to influence the development of agoraphobia. RESULTS: 'Earlier age of onset', 'fear of losing control' and 'chills or hot flushes' turned out to correlate statistically significantly with PDA, while 'chest pain or discomfort' occurred more often in PDU. LIMITATIONS: The present study used retrospective data. CONCLUSIONS: The results of this study suggest that the development of agoraphobia in panic disorder is influenced by specific variables and is not a purely coincidental process.

[Frequency of immunologic disorders in acute schizophrenia]. / Zur Häufigkeit immunologischer Auffälligkeiten bei akuten Schizophrenien.

Immunological examinations in schizophrenic patients have shown that there are many alterations in both arms of the immune system, i.e. cellular and humoral activities. The results are quite heterogeneous, as not even all schizophrenics show these pathological changes. Immunological findings are assumed to be etiopathogenetically related to the disease process or to be an epiphenomenon. The present study supposes that immunological alterations as they can be found during the course of schizophrenia may be an indicator for somatic vulnerability or an epiphenomenon. 60 male inpatients, fulfilling DSM-IV criteria of schizophrenia where examined during their acute phases of psychosis and during their phases of clinical improvement, by means of a serological profile including cellular and humoral parameters. The control group consisted of 42 healthy male volunteers. It was the aim of this study to find out if there were (a) overall differences in the immune profiles between patients and control group and (b) differences between different categories of schizophrenic disorder. During the acute phase nearly half of the schizophrenic patients showed pathologic immunological parameters, whereas none of the controls did. During the phase of clinical improvement the number of patients with normal immunological findings predominated. Furthermore there was a difference between the Paranoid and the Disorganized Subtype, the latter showing more immunological abnormalities. The results of this study give further support to the hypothesis that immunological aberrations should not be seen as closely etiopathogenetically related to schizophrenic disorders, but rather as an epiphenomenon (e.g. as a stress marker) and/or as indicators for somatic vulnerability.

Prevalence, patterns and role of personality disorders in panic disorder patients with and without comorbid (lifetime) major depression.

A total of 84 consecutive out-patients from the Anxiety Disorders Clinic of the Psychiatric University Hospital in Graz with a current panic disorder were diagnosed for Axis I and II disorders using the Structured Clinical Interviews for DSM-III-R. The subjects were divided into two groups: (i) 49 patients who met the criteria for panic disorder with or without agoraphobia and had no history of an affective disorder and (ii) 35 patients who had a (lifetime) comorbidity of a major depressive disorder. There was a statistically significant difference in the prevalence of personality disorders between the two groups, which was due to the higher frequency of narcissistic personality disorder in the comorbid sample. Logistic regression analysis revealed that agoraphobia and/or major depression were associated with personality disorders, thus indicating that the relationship between panic disorder, agoraphobia and major depression is not straightforward, but is strongly influenced by the presence of Axis II disorders. Furthermore, the results of this study provide support for the 'unitary position' concerning the relationship between panic disorder and depression.

Pharmacotherapy of alcohol dependence.

The current pharmacotherapeutic approaches to alcohol dependence, together with the results of a number of clinical trials, are reviewed in this article. Despite the somewhat disappointing clinical results, pharmacotherapeutic interventions did lead to some small, but significant, improvements in alcohol abstinence rates.

Can cannabis trigger recurrent panic attacks in susceptible patients?

Cannabis has been reported to produce acute psychiatric reactions, among these panic anxiety and derealization, which are self-limited. We report on three patients who experienced an initial panic attack during cannabis intake. Anxiety attacks reoccurred after the cessation of intake. Two of these patients had a current depressive disorder, one of them had a single Grand Mal seizure before the onset. We suggest that cannabis may trigger the emergence of recurrent panic attacks and uncover latent panic disorders in vulnerable persons.

[Effect of mianserin and additional fluid intake on depression and blood urea concentration in elderly patients]. / Der Einfluss von Mianserin und zusätzlicher Flüssigkeitszufuhr auf die Depression und die Blutharnstoff-Konzentration älterer Patienten.

36 elderly outpatients (mean age 68.6 years) with depression and increased blood urea level were treated with mianserin (60 mg every evening). All patients were ordered to drink additionally 11 of mineral water per day, which only 30 patients complied with. The patients who complied with the ordered increase in fluid intake (responder, n = 30) showed in comparison to those who did not comply (non-responder, n = 6) a significant improvement in depression (i.e., HAM-D, p < 0.001) after a four week period of treatment (t2). The responders' blood urea level normalized whereas the non-responders' level, although lowered, still remained in the pathological range.

[Changes in disordered motor skills in depressed right handed patients due to antidepressive therapy]. / Veränderungen der gestörten motorischen Wendigkeit bei depressiven, rechtshändigen Patienten durch antidepressive Therapie.

30 right-handed male and female inpatients with Major Depression diagnosed with the Diagnostic and Statistical Manual of Mental Disorders, revised Third Edition, (DSM-III-R) were investigated with reference to the retarded motor activity of their dominant hand. The treatment included antidepressants, neuroleptics and tranquilizers. The tests (handedness test, HDT; a test showing evaluation for the degree of depression, TSD; a test for mood disturbance, EWL) were carried out at the onset of drug treatment (t1) and after improvement of the depression (t2). Both motor retardation and the scores of the depressivity-tests ameliorated significantly.
