Is valproate promising in cardiac fatal arrhythmias? Comparison of P- and Q-wave dispersion in bipolar affective patients on valproate or lithium-valproate maintenance therapy with healthy controls.

Autonomic nerve system is considered to be involved in bipolar affective disorder (BAD) or to be influenced by valproate monotherapy or valproate plus lithium combination. We planned to assess the effects of medication on atrial and ventricular conduction. The electrocardiography records were performed with eligible 15 patients with valproate, 20 patients with lithium-valproate combination use in euthymic phases of BAD and 20 healthy participants. The blood valproate and lithium concentrations in groups were in normal range. The difference in P maximum, P minimum, maximum QTc were statistically insignificant. Minimum QTc (F = 6.36; df = 2; P = 0.003) and QT dispersion (QTD) (F = 5.57; df = 2; P = 0.006) were statistically significant among the groups. There were no significant differences between patient groups among ECG parameters. Minimum QTc was significantly longer in combination group than healthy controls, whereas the QTD values in both patient groups were significantly lower than controls'. Valproate might have some preventive effects on ventricular electrical conduction because of lower QTD in both patient groups. Thus, valproate seems to have cardiac conduction stabilizing effect beside its mood stabilizing aspect. However, this finding needs replication and further corroboration in well-designed studies.

Olanzapine treatment in Jarisch-Herxheimer reaction due to neurosyphilis with dementia: a case report.

We discussed a neurosyphilis case who had a risky sexual intercourse history nearly 10 years ago. After the neurosyphilis diagnosis, the patient has clinical symptoms of a demential case starting as a typical manic episode and Jarisch-Herxheimer reaction because of intravenous penicillin treatment that has improved with olanzapine treatment.

Effect of informed consent for intravascular contrast material on the level of anxiety: how much information should be given?

PURPOSE: To compare the effect of two different informed consent forms on patients' anxiety level prior to intravenous contrast material (IVCM) injection. MATERIAL AND METHODS: Two different informed consent forms were randomly given to 265 consecutive patients referred for either intravenous pyelography or computed tomography requiring IVCM injections. Form 1 had brief information, including only the common risks and risk factors associated with IVCM, while Form 2 had more comprehensive information. Before being presented with the two different informed consent forms, 191 of the 265 patients filled out two other forms evaluating: 1: How they felt in that particular situation/moment (STAI-T); and 2: How they felt independently of the situation or condition at that moment (STAI-S). After the patients were informed, the STAI-T (measuring how they felt in that particular situation) was filled out once more to see if the anxiety level had changed. RESULTS: The anxiety level for 88 patients receiving Form 1 decreased after they were given the informed consent (P=0.033). However, among the 103 patients receiving Form 2, the anxiety level showed a significant increase (P=0.001) compared to the values obtained before Form 2 was given. CONCLUSION: These results indicate that informed consent, including brief information about the risk factors and potential adverse reactions of IVCM, reduces anxiety level, while detailed information before the procedure increases the anxiety level.

Sociodemographic and clinical characteristics of patients with conversion disorder in Eastern Turkey.

BACKGROUND: Conversion disorder (CD) is a common disease and its importance still continues in Turkey and particularly in Eastern Turkey. The aim of this study is to examine sociodemographic and clinical characteristics of CD. METHOD: Among 198 consecutive patients having CD diagnosed by structured DSM-III-R clinical interview, the psychosocial characteristics of the patients were clinically investigated. RESULTS: The most common subtype of CD was non-epileptic seizure (NES) (41.4 %). The psychosocial stress factors were found in the initiation or at the last episode of the disorder (88.9 %). The most prominent problem related with primary support group was traumatic event (37.9 %) followed by problems associated with migration and related economical problems which are the most important problems of the study area. The incidence of depressive disorders was high in patients with CD, and the histrionic personality disorder was the most prominent personality pathology among the patients. Direct referral to psychiatry clinics appeared to be low (12.1 %). CONCLUSION: Our findings have shown that traumatic events may have an important role in the occurrence, severity and duration of CD, and most of the patients seek help from religious healers. The study has also revealed that lower education level and socioeconomic and sociocultural problems may play a role in the occurrence of the disorder as well as regarding its course.

Quetiapine augmentation in patients with treatment resistant obsessive-compulsive disorder: a single-blind, placebo-controlled study.

Recently, atypical antipsychotics have been used for the management of the patients with refractory obsessive-compulsive disorder (OCD). The aim of the present study was to evaluate the results of quetiapine augmentation to a serotonin reuptake inhibitor (SRI) in the patients with refractory OCD. Fifty-two patients with OCD according to DSM-IV entered 3 months of an open-label phase treatment with a SRI with or without concomitant adjunctive treatment regimen. Of them, 27 patients were refractory OCD. These patients were randomly divided into two groups, SRI plus quetiapine and SRI plus placebo, for an 8-week single-blind phase. The course of OCD was evaluated by Yale-Brown Obsession-Compulsion (Y-BOCS) and Clinical Global Impression-Severity of Illness and Improvement (CGI-SI and I) Scales every other week for 8 weeks. Of the 14 patients in group I, nine (64.4%) showed significant improvement with 60% or greater improvement on the Y-BOCS and one (7.1%) partial improvement with 30% or greater improvement on the Y-BOCS, whereas no improvement was observed in group II. The addition of quetiapine to ongoing SRI therapy has been found to be effective and well-tolerated approach in patients with refractory OCD.
