Acute stress disorder and post-traumatic stress disorder following traumatic amputation.

Traumatic amputations are important causes of acute stress disorder and post-traumatic stress disorder. In this study, we aimed to find out the occurrence rate of symptoms of acute and post-traumatic stress disorder after traumatic amputations and according to this, to assess the psychiatric status of the patients in the postoperative period. Twenty-two patients with traumatic limb amputation who were treated in our institution were retrospectively evaluated. During the early post-traumatic period, the patients were observed to determine whether they needed any psychiatric supportive treatment. During the follow-up period, after the sixth month from the trauma, the patients were referred to the psychiatry department and they were evaluated to determine whether they needed any psychiatric supportive treatment, by clinical psychiatric examination and use of the 'post-traumatic stress disorder scale' (Clinician Administered Post traumatic Scale, or CAPS). Twenty-one (95.5%) of 22 patients were male, one (4.5%) female. Mean age of the patients was 40.8 years (range: 15 to 69). During the early posttraumatic period, 8 (36.3%) of these patients consulted the psychiatry clinic following the orthopaedists' observations. Five (22.7%) of these patients needed psychiatric supportive treatment for acute stress disorder. After the 6th month (6 months to 5 years), 17 (77.2%) had chronic and delayed post-traumatic stress disorder and needed psychiatric supportive treatment. Patients who have sustained a traumatic amputation may need psychiatric supportive treatment in the late period after the trauma. As we orthopaedic surgeons treat these patients surgically, we should be aware of their psychiatric status.

[Combination therapy using sertraline with sleep deprivation and light therapy compared to sertraline monotherapy for major depressive disorder]. / Majör depresyonda sertralin ile birlikte uygulanan uyku yoksunlugu ve isik tedavisinin etkinliginin sertralin tedavisi ile karsilastirilmasi.

OBJECTIVE: Bright light therapy is effective and well tolerated in seasonal affective disorder and some studies reported an antidepressant effect of bright light also in non-seasonal depression. On the other hand, total sleep deprivation leads to a rapid and marked improvement of mood in 60% of depressed patients. Combinations of antidepressant medication with those somatic therapies are generally indicated. The aim of this study was to compare the efficacy of the combination of sertraline and partial sleep deprivation or light therapy with sertraline monotherapy in the treatment of major depression. METHOD: Thirty-seven patients with major depressive disorder were randomly allocated into 3 treatment groups. Thirteen were treated with sertraline and late partial sleep deprivation, 13 with sertraline and bright light therapy and 11 sertraline monotherapy as a control group. Outcome measures included daily (first 15 days) and weekly Hamilton Rating Scale for Depression and biweekly Hamilton Anxiety Rating Scale. RESULTS: Partial sleep deprivation group improved significantly and more rapidly. Accelerated treatment response was shown in sleep deprivation group that improvement was observed after the third day. Bright light and sleep deprivation combinations with sertraline were more effective than sertraline monotherapy for accompanied anxiety in depression. CONCLUSION: Late partial sleep deprivation in combination with sertraline can accelerate and increase the treatment response in non-seasonal major depressive disorder.

Delirium and extrapyramidal symptoms due to a lithium-olanzapine combination therapy: a case report.

We report an elderly patient who developed severe delirium and extrapyramidal signs after initiation of lithium-olanzapine combination. On hospital admission, serum levels of lithium were found to be 3.0 mM/L which were far above toxic level. Immediate discontinuation of both drugs resulted in complete resolution of most of the symptoms except for perioral dyskinesia which persisted for three more months. We critically discussed the differential diagnosis of lithium intoxication and assessed confounding factors which induce delirium and extrapyramidal signs related with combination therapy of lithium and olanzapine.

Clastogenicity of selective serotonin-reuptake inhibitors.

OBJECTIVE: Selective serotonin-reuptake inhibitors (SSRIs) are used in the treatment of various forms of psychiatric disorders. Preclinical studies in laboratory animals have indicated that SSRIs were not genotoxic, but clear results from in vitro testing of SSRIs in a human cell system are currently scarce. The purpose of this study was to investigate whether SSRIs might be genotoxic. Sertraline was chosen as model SSRI, since it appears to be at least as well-tolerated as other SSRIs and may even have a more favourable side-effect profile. Unlike fluoxetine, fluvoxamine and paroxetine, sertraline has low potential for pharmacokinetic drug interactions. So, sertraline would be considered first in the treatment of psychiatric disorders requiring SSRI therapy in the future. We therefore examined peripheral lymphocytes from sertraline-treated patients for both sister chromatid exchanges (SCEs), cells with a high frequency of SCEs (HFC) and chromosome aberrations (CA) to evaluate the clastogenicity of SSRIs. METHOD: Ten sertraline-treated patients meeting 'Structured Clinical Interview for DSM-IV' criteria for both generalized anxiety disorder and major depression were compared with 18 healthy volunteers and 18 non-treated patients with similar psychopathology. Sertraline hydrochloride was administered orally at 50 mg daily for 10 months to 1 year. The participants were selected on the basis of similar responses to a questionnaire assessing risk of genotoxicity related to other aspects of life. All participants had very similar lifestyles, medical histories, biological and dietary factors. All subjects were non-smokers. RESULT: A statistically significant difference between patients with both generalized anxiety disorder and major depression (sertraline-treated or non-treated) and healthy volunteer groups was found by both SCE frequencies and HFC percentages. Both patient groups showed higher frequencies of SCEs than the healthy controls. No statistically significant difference was found between SCE frequencies or HFC percentages observed in sertraline-treated and non-treated patient groups. No statistical difference was found between groups with respect to the frequency of CA. CONCLUSION: There are no adequate studies analysing the clastogenicity of SSRIs, in particular of sertraline. The SCE frequency, the percentage HFC and the frequency of CA in patients with both generalized anxiety disorder and major depression exposed to daily doses of sertraline do not indicate a possible clastogenic hazard. The increased SCE frequencies in patients with both generalized anxiety disorder and major depression in our study-irrespective of sertraline treatment-indicate a possible genotoxic effect. However, our observations were based on a limited number of patients; the results may be explained by psychogenic stress.

Increased serum tumor necrosis factor-alpha levels and treatment response in major depressive disorder.

RATIONALE: Over the last 15 years, an increasing body of evidence has suggested a causal relationship between depression and the immunological activation and hypersecretion of pro-inflammatory cytokines, such as interleukin-1, interleukin-6 and tumor necrosis factor-alpha (TNF-alpha). However, little is known about the probable relationship of serum TNF-alpha with major depressive disorder (MDD). OBJECTIVE: To assess whether serum TNF-alpha levels could be associated with the clinical course of MDD. SUBJECTS AND METHODS: TNF-alpha and C-reactive protein (CRP) serum concentrations, erythrocyte sedimentation rate, and leukocyte count were measured in 26 MDD patients and in 17 controls. The measurements were repeated following 6 weeks of antidepressant treatment with selective serotonin re-uptake inhibitors. Psychopathological improvement and the severity of depression were evaluated with the Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI). RESULTS: On admission, serum TNF-alpha and leukocyte count were significantly higher in MDD patients compared to controls ( P<0.001 and P=0.005, respectively). With the antidepressant treatment, both HAMD and BDI scores decreased significantly (P<0.001 for both). Comparison of pre- and post-treatment measurements revealed that TNF-alpha, CRP, and leukocyte count decreased to levels comparable with those of the control subjects ( P<0.001, P=0.01, and P=0.01, respectively). CONCLUSIONS: The results emphasized that some immunological parameters, such as CRP, leukocyte count and TNF-alpha, are significantly involved in the clinical course and treatment response in MDD. TNF-alpha in particular could be considered as a potential state marker in MDD.

Seasonal affective disorder in eight groups in Turkey: a cross-national perspective.

OBJECTIVE: Previous estimates of the prevalence of seasonal affective disorder (SAD) in community-based samples generally originated from western countries. We report prevalence rates in eight groups from four latitudes in Turkey. METHOD: Seasonal Pattern Assessment Questionnaire (SPAQ) was distributed to the community-based samples from eight different locations at four latitudes in Turkey. The prevalence rates of winter SAD and subsyndromal SAD (S-SAD) were estimated for the four groups at the same latitudes by using SPAQ responses. RESULTS: We distributed 3229 SPAQs, had an overall response rate of 54.16% and 1749 SPAQs were included in the analyses. Seasonality was reported as a problem by 549 subjects (31.57%) of our 1749 respondents. Prevalence of winter SAD and S-SAD are estimated as 4.86 and 8.35%, respectively, for the whole group. Prevalence rates were determined for each center and for four latitudes (two centers at the same latitude were grouped as one). In Adana-Gaziantep (lt. 37), Izmir-Elazig (lt. 38), Eskisehir-Ankara (lt. 39) and Trabzon-Edirne (lt. 41), the prevalence rates for winter SAD were 6.66, 2.25, 8.00 and 3.76%, respectively. CONCLUSIONS: Our prevalence estimates of winter SAD are similar to those found in previous community-based studies at the same latitudes; no correlation was found between latitude and prevalence of winter SAD, which could be related to the sampling methodology or to the fact that there were only 5 degrees of difference between the latitudes.
