[Show abstract][Hide abstract] ABSTRACT: The aim of the present study was to assess the occurrence of obsessive-compulsive symptoms (OCS) in schizophrenic patients treated with clozapine, and to examine the relationship between OCS and other clinical variables. The results support earlier findings which suggest that clozapine produces or unmasks OCS. In addition, the severity of OCS was not related to other dimensions of psychopathology, severity of illness, clinical improvement or dose and duration of clozapine treatment.

[Show abstract][Hide abstract] ABSTRACT: Creutzfeldt-Jakob disease (CJD) is a rapidly progressive prion disease that causes deficits involving movement, cognition, and mental status. The clinical heterogeneity of the disease can make diagnosis difficult. Thorough neurologic, cognitive, and psychiatric examinations are necessary for observing its clinical features. In this case report we describe a 62-year-old male patient who was initially followed with a diagnosis of depression and later was diagnosed with CJD. The patient had a one-year history of anhedonia, loss of interest, social withdrawal, anxiety and decrease in speech and was given paroxetin 20 mg/day with a diagnosis of depression. During follow up, neurological symptoms including ataxia and rigidity became evident and dementia and akinetic mutism developed in a rapidly progressive course. Although electroencephalography (EEG) and magnetic resonance imaging (MRI) revealed nonspecific findings initially, typical findings for CJD were seen during the follow up. The positive 14-3-3 protein in CSF supported the diagnosis. The aim of this report is to emphasize the fact that CJD may present with different psychiatric symptoms and can be initially misdiagnosed. CJD should be considered in the differential diagnosis of patients who have focal neurological signs in addition to psychiatric symptoms. Repeated neurological examinations, EEG and cranial MRI may help in the diagnosis of these patients.

[Show abstract][Hide abstract] ABSTRACT: On clinical grounds, somatosensory evoked potentials (SEP) and motor evoked potentials (MEP) are currently used to discriminate between hysterical and neurological conditions. The present paper reports on two patients with severe gait disturbance who had the near-total absence of SEP responses on the scalp during the symptomatic period, which normalized after recovery. These findings, along with others, may shed light on the brain correlates of conversion phenomena.

[Show abstract][Hide abstract] ABSTRACT: Selective serotonin reuptake inhibitors (SSRIs) are currently used as a first-line treatment for depression, as they have a favorable side-effect profile. Escitalopram, a new SSRI, is also well-tolerated and serious side effects are rarely associated with its use. There have been several reports that SSRIs might increase bleeding tendency in some patients by affecting platelet function. However, to our knowledge, there have been no reports about their relation to thrombosis. In this brief report, we present a case of venous thromboembolism associated with escitalopram in a patient with psychotic depression without any major risk factors for thrombosis. SSRIs might have a dual effect on platelet function. The immediate and early effect of SSRI use on platelets might be an increase be an in tendency for thrombosis, whereas the late effect after repeated dosing might be an increase in tendency to bleed, as suggested by previous literature.

[Show abstract][Hide abstract] ABSTRACT: This cross-sectional study investigated whether a group of unmedicated patients with major depressive disorder, single episode, had decreased bone mineral density (BMD). The BMD at the lumbar spine and proximal femur in 25 premenopausal women with major depressive disorder and 15 normal women was measured by dual-energy X-ray absorptiometry. Bone turnover markers and serum cortisol levels were also evaluated for each subject. As compared with values in the normal women, the mean BMD in the depressed women was significantly lower at the lumbar spine and at all sites of the proximal femur. There was no statistically significant difference between serum cortisol levels and bone turnover markers except for significantly higher urinary excretion of deoxypyridinoline cross-links in the patients compared with the controls. In conclusion, depressed women may have decreased BMD even at the very early stages of the illness, and this possibility should be taken into consideration in treatment.

[Show abstract][Hide abstract] ABSTRACT: (a) To investigate the prevalence of neurological soft signs (NSS) in schizophrenic patients and their nonpsychotic siblings and (b) to examine the clinical correlates of NSS in the schizophrenic group.
Ninety-nine schizophrenic patients, 80 of their nonpsychotic siblings and 59 healthy controls were included in the study. NSS were assessed with the Neurological Evaluation Scale (NES). Psychiatric assessment of the patients was conducted with the Positive and Negative Syndrome Scale (PANSS). Siblings and the control group were evaluated with Schedules for Clinical Assessment in Neuropsychiatry (SCAN) to determine the presence of any past or current psychotic disorder.
Schizophrenic patients had significantly higher scores overall and on each subscale of NES than the sibling and control groups. The sibling group's scores were intermediate between those of the schizophrenic patients and those of the healthy controls. All subscale scores and the total NES scores correlated positively with the negative symptoms subscale scores of PANSS. The general psychopathology subscale scores of PANSS also showed a positive correlation with all subscale scores of NES, except the 'sequencing of complex motor acts' subscale. The total NES scores of the patients as well as their scores for the 'sequencing of complex motor acts' and 'others' subscales were significantly correlated with the respective scores of their own siblings.
These results support the findings of previous studies suggesting that there might be common genetic and/or environmental factors in the pathogenesis of neurological impairment in schizophrenic patients and their siblings. They also indicate that neurological soft signs in schizophrenic patients are associated with prominent negative symptoms.
