[Limb apraxia].

Apraxia is the disturbance of planning and of execution of motor activity. It is not caused by a lesion or a disturbance of the motor or sensory nervous system, it is elicited by a dysfunction of an area in the left cortex of the brain. This area in the left fronto-parietotemporal hemisphere is located right beside the area for speech. Therefore it is not unusual that patients with apraxia suffer from aphasia as well. The two different types of limb apraxia are ideomotor apraxia and ideational apraxia. Ideomotor apraxia is apraxia without tool use, it includes imitation of positions of hands and fingers, performance of gestures on demand, and pantomime of object use. Ideational apraxia is apraxia with tool use like cutting with a knife or utilizing a pencil.

Soluble interleukin 2 receptor levels, temperament and character in formerly depressed suicide attempters compared with normal controls.

An imbalance of the immune system and mixed personality profiles in suicide attempters have been reported. As suicidal behavior is common in patients with psychiatric disorders within the spectrum of depressive features, in this study we measured soluble interleukin-2 receptor concentrations in plasma (sIL-2R) and investigated temperament and character profile and their potential correlation in formerly depressed patients with a history of suicide attempt. We studied sIL-2R levels in plasma and personality characteristics (using Cloninger's Temperament and Character Inventory [TCI]) of formerly depressed patients who had attempted suicide a mean of 3 years previously (n = 25), and age and gender matched normal controls (n = 25). There was no significant difference in sIL-2R levels between formerly depressed suicide attempters and age and gender matched normal controls (0.23 ng/ml +/- 0.25 vs. 0.19 ng/ml +/- 0.16). When compared to normal controls, suicide attempt patients had a significantly higher score on the temperament dimension "harm avoidance" and a lower score on the character dimension "self-directedness." No significant correlation was found between sIL-2R values and TCI dimensions. We propose that the liability to suicidal behavior among suicide attempters susceptible to depressive symptomatology may be related to high harm avoidance and low self-directedness.

Somatic symptoms in depression.

Both painful and nonpainful somatic symptoms essentially characterize clinical states of depressive mood. So far, this well-established psychopathological knowledge has been appreciated only insufficiently by the official diagnostic systerms of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV TR) and the ICD-10 Classification of Mental and Behavioral Disorders. Clinical Descriptions and Diagnostic Guidelines (ICD-10). From a perspective of primary care services, this unmet diagnostic need is deplorable, as the main mode of presenting a depression is by reporting somatic symptoms. This somatic form of presentation, however, significantly contributes to low rates of recognition in primary care. A diagnostic challenge may be seen in the differentiation of a depression with prevailing somatic symptoms from anxiety, somatoform disorders, and medical conditions. When somatic symptoms, particularly painful physical conditions, accompany the already debilitating psychiatric and behavioral symptoms of depression, the course of the illness may be more severe, implying a higher risk of early relapse, chronicity, suicide, or mortality due to other natural causes, the economic burden increases considerably the functional status may be hampered heavily, and health-related quality of life may be lowered dramatically. The neurobiological underpinnings of somatic symptoms in depression may guide more promising treatment approaches.

[Psychopharmacotherapy in somatic diseases -- treatment principles in daily medical routine].

Up to 46.5% of general hospital inpatients suffer from clinically relevant psychiatric disorders. Appropriate psychopharmacotherapy of comorbid mental disorders in the medically ill can have positive effects on the course of somatic illness and can enhance quality of life in patients with medical or neurologic conditions. However, treating psychiatric disorders in this population can often be challenging, even for the most seasoned clinicians. An increasingly important issue in daily medical routine when prescribing medications is the possibility that a newly prescribed drug may interact with existing pharmacotherapy. Most often the concern is to avoid adverse consequences, such as undermining the effectiveness of previously stable drug therapy or precipitating the appearance of new adverse events. We have used the examples of Parkinson's disease, epilepsy and cardiovascular disease commonly associated with mental disorders to illustrate how these considerations affect the clinician's choice of a psychotropic drug in the medically ill.

[Somatoform and factitious disorders in clinical medicine].

Patients with "medically unexplained somatic symptoms" are frequent in every health care system. The bodily complaints may persist over a long period of time, cause serious subjective suffering and be associated with secondary psychiatric comorbidity and major disabilities in psychosocial life. The doctor-patient relationship is often hampered by emotional conflicts, leading to unsuccessful treatment, doctor-shopping and chronic courses of illness. A major subgroup of patients with somatoform disorders and a minor subgroup of patients with self-induced, i.e., factitious disorders must be differentiated, both showing a complex etiopathogenesis of their somatic symptoms. Patients with somatoform and factitious disorders present a special challenge within the health care system.

The influence of psychotropic drugs on cerebral cell death: female neurovulnerability to antipsychotics.

Tissue transglutaminase (tTG) is a marker for apoptosis, and its protein level is known to be increased in post-mortem Alzheimer's and Huntington's disease brains. tTG is increased in the cerebrospinal fluid of patients with Alzheimer's disease. However, the influence of psychotropic medication on acute cell death has not been studied so far in vivo, although some experiments performed in vitro suggest that antipsychotic drugs are neurotoxic. The protein level of tTG was examined in the cerebrospinal fluid obtained from 29 patients under neuroleptic medication in the last 24 h before lumbar puncture (eight patients diagnosed with Alzheimer's disease and 21 patients with other neurological diseases), and compared with those from 55 patients without antipsychotic medication (25 Alzheimer's patients and 30 others). In addition, the influence of several other psychotropic drugs on apoptosis was analysed. A significant influence (P<0.01) of antipsychotic drugs for both the Alzheimer's and the non-Alzheimer's group was found with respect to tTG protein levels in cerebrospinal fluid. By contrast to the male subgroups, the female groups showed a strong influence of neuroleptics on cerebral cell death. Surprisingly, atypical antipsychotics did not differ from typical neuroleptics in neurotoxicity. By contrast, no influence of antidepressants, cholinesterase-inhibitors, nootropics, tranquilizers and tramadol on cerebral cell death was found. The results suggest that typical and atypical antipsychotic drugs may induce cerebral cell death, especially in female patients. Subjects with Alzheimer's disease might be even more vulnerable to any antipsychotic. Therefore, subsequent research should aim to identify atypical neuroleptics without neurotoxicity. A limit on the use of first- and second-generation antipsychotics in elderly patients is proposed. Finally, the possible connection between the observed increased cerebral cell death and tardive dyskinesia, the most threatening side-effect in antipsychotic therapy, is discussed.

Amantadine in the akinetic-rigid variant of Huntington's disease.

OBJECTIVE: To report the effects of amantadine on an akinetic-rigid variant of Huntington's disease (HD). CASE SUMMARY: We describe a 36-year-old woman with HD who was treated with intravenous amantadine for 5 days. The woman was evaluated with the Unified Huntington's Disease Rating Scale before and after treatment. Parkinsonism, bradykinesia, and dystonia improved significantly. DISCUSSION: Amantadine is a noncompetitive N-methyl d-aspartate receptor antagonist. It is mainly used in the treatment of Parkinson's disease, as it increases dopamine levels in the brain. This effect is said to ameliorate akinesia. Although the effect of amantadine on choreatic dystonia in HD has been reported in several studies, to the best of our knowledge, this is the first report of the ameliorative effects of amantadine on the rigid form of HD. Our patient showed improvements of gait, parkinsonism, and dystonia. Fine-motor tasks and eye movement did not change significantly. CONCLUSIONS: We suggest that amantadine treatment might be of value to patients with the akinetic-rigid variant of HD.

Stress doses of hydrocortisone, traumatic memories, and symptoms of posttraumatic stress disorder in patients after cardiac surgery: a randomized study.

BACKGROUND: Traumatic experiences associated with cardiac surgery (CS) can result in traumatic memories and posttraumatic stress disorder (PTSD). Because it is known that subjects who develop PTSD often show sustained reductions in circulating cortisol concentrations, we performed a prospective, randomized study to examine whether exogenously administered stress doses of hydrocortisone during the perioperative period of CS reduces the long-term incidence of chronic stress and PTSD symptoms. METHODS: Patients (n = 91) were prospectively randomized to receive either stress doses of hydrocortisone or standard treatment during the perioperative period of CS. Of 48 available patients at 6 months after CS, 26 had received stress doses of hydrocortisone and 22 standard treatment. Traumatic memories and PTSD symptoms were diagnosed with previously validated questionnaires. RESULTS: As compared with patients after standard therapy, patients from the hydrocortisone group had significantly lower chronic stress symptom scores (p <.05). There was no significant difference regarding the number or type of traumatic memories between the hydrocortisone and the standard treatment groups. CONCLUSIONS: Stress doses of hydrocortisone in patients undergoing CS are associated with a lower intensity of chronic stress and PTSD symptoms at 6 months after CS.

Neuroprotection in Huntington's disease: a 2-year study on minocycline.

Huntington's disease (HD), a relentlessly progressive neurodegenerative disorder, is characterized by a clinical triad of psychiatric, cognitive and motor disturbances. The antibiotic minocycline, a caspase inhibitor exhibiting antiapoptotic properties, has been shown to prolong survival in the transgenic mouse model of HD. We administrated minocycline to 14 patients with genetically confirmed HD. The patients were psychiatrically, neurologically and neuropsychologically evaluated at baseline, and after 6 and 24 months of treatment, using the Unified HD Rating Scale and a neuropsychological test battery. After 12 months, three patients were lost to follow-up so that 11 patients were analysed at the endpoint. Minocycline was well tolerated. Unlike the expected natural course of HD, patients exhibited stabilization in general motor and neuropsychological function at endpoint, after improving in the first 6 months. Moreover, we found a significant amelioration of psychiatric symptoms that was not apparent after the first 6 months. In detail, the Mini-Mental State Examination, the Total Motor Score, the Total Functional Capacity Scale and the Independence Scale, as the most prominent scales in HD, were stabilized after 3 years of treatment. Our results confirm previous animal studies and indicate a neuroprotective effect of this agent in HD. A long-term, double-blind, placebo-controlled trial appears highly warranted for definitively establishing the value of minocycline in HD.

Exposure to high stress in the intensive care unit may have negative effects on health-related quality-of-life outcomes after cardiac surgery.

OBJECTIVE: Up to 20% of patients do not show improvements in health-related quality of life (HRQL) after cardiac surgery, despite apparently successful surgical procedures. We sought to determine whether failed improvements in HRQL after cardiac surgery are associated with the development of traumatic memories and chronic stress states as a result of high perioperative stress exposure. DESIGN: Prospective cohort study. SETTING: A 10-bed cardiovascular intensive care unit of a tertiary care university hospital. PATIENTS: A total of 148 cardiac surgical patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The patients were evaluated for traumatic memories from postoperative treatment in the cardiovascular intensive care unit (defined as the subjective recollection of pain, respiratory distress, anxiety/panic, and nightmares), symptoms of chronic stress, including those of posttraumatic stress disorder, and HRQL preoperatively (at baseline) and at 6 months after cardiac surgery. A state of chronic stress was defined as the development of posttraumatic stress disorder at 6 months after surgery. Factors predicting the decline in HRQL were determined by multivariable linear regression. Twenty-seven patients (18.2%) had posttraumatic stress disorder at 6 months after cardiac surgery; seven of these patients (4.8%) had evidence of preexisting posttraumatic stress disorder before undergoing cardiac surgery. Patients with new posttraumatic stress disorder at 6 months after cardiac surgery had a significantly higher number of traumatic memories from postoperative treatment in the cardiovascular intensive care unit (p =.01). A multiple regression model included the number of traumatic memories from the intensive care unit and stress symptom scores at 6 months after heart surgery as predictors for variations in physical HRQL outcome scores (R2 =.30, p <.04). Stress symptom scores were the most significant predictors of mental health HRQL outcomes (R2 =.52, p <.01). CONCLUSIONS: Exposure to high stress in the cardiovascular intensive care unit can have negative effects on HRQL outcomes of cardiac surgery.

Ziprasidone in Huntington's disease: the first case reports.

Huntington's disease (HD) is a relentlessly progressive neuropsychiatric disorder with an underlying autosomal dominantly inherited genetic defect. Classical antipsychotics (i.e. phenothiazines or butyrophenones) are the most used medication to reduce the (probably dopamine-born) choreiform hyperkinesias. Ziprasidone is the latest of a new class of atypical antipsychotics; it has not been studied so far in this indication. We report three genetically confirmed HD patients who improved significantly in several categories of the motor scale of the Unified HD Rating Scale.

[Capacitive requirement for acute in-patient care of patients with psychosomatic diseases in bavaria].

Estimations of the requirement for acute in-patient care of patients with psychosomatic diseases in Bavaria have to rely on respective data on their incidence and prevalence as valid requirement data are missing. The required capacity of in-patient beds depends on several, inconsistently figured parameters: hospitalization rate, length of stay, occupancy rate. Based on conservative assumptions the hospitalization rate was calculated to be at least 1.3 admissions per 1000 and for adequate treatment the average length of stay should not be limited to less than 50 days. In order to avoid unnecessary delay of treatment a realistic occupancy rate has to be 90 %. Thus the minimal capacity for in-patient care is assessed to be 2453 beds. At present patients with psychosomatic diseases in Bavaria receive in-patient treatment in psychosomatic departments of general hospitals, hospitals and rehab clinics of psychosomatic and psychotherapeutic medicine, and in hospitals of psychiatry and psychotherapy, in each with a different focus. When the expertise was drafted these acute care and rehab hospitals provided some 2500 beds - with only 76 beds in general hospitals. For quality assessment of the available beds for in-patient care and future planning minimal standards of structural quality have to be consented. At present it is not possible to make a clear and substantial distinction between the treatment for patients with psychosomatic diseases in acute-care hospitals and in psychosomatic rehab clinics respectively. Thus, the necessary in-patient rehab capacity can only be assessed roughly. The existing pluralism of the in-patient care providing system for patients with psychosomatic diseases is considered to be appropriate for different needs of this patient group. In the future excellent care for this patient group will acknowledge options for a more flexible and interconnected care-providing system. This is a publication of the complete expertise by the project group "Acute In-patient Care for Patients with Psychosomatic Diseases in Bavaria" which has been handed to the Bavarian Ministry of Social Affairs in December 1999.

[Munchhausen patients in general hospitals--Clinical features and treatment approaches in C-L psychiatry settings].

Factitious disorders have been reported in 0.5 - 1 % of general hospital patients. It often takes several years until the disorder is detected. During this period, enormous health care cost can arise not least out of iatrogenic self-induced mutilations and related secondary somatic complications. Apart from surgeons and physicians, consultation-liaison (C-L) psychiatrists are particularly called on to diagnose factitious disorders at an early stage in order to avoid unnecessary diagnostic and therapeutic procedures, treatment dropout and doctor shopping. This article gives an overview of clinical features and treatment approaches in C-L psychiatry settings.

Psychiatric and psychosocial outcome of cardiac surgery with cardiopulmonary bypass: a prospective 12-month follow-up study.

Little is known concerning the natural history of psychiatric morbidity, postoperative delirium, cognitive decline and health-related quality of life (HRQOL) in cardiac surgery patients and the impact of neurocognitive dysfunction on HRQOL after cardiac surgery with cardiopulmonary bypass (CPB). In a prospective study, we followed up for 1 year 30 of the original 34 patients who had undergone cardiac surgery with CPB. Patients were assessed preoperatively, before discharge, and at 1 year after surgery with the Structural Clinical Interview for DSM-IV and a series of neuropsychological tests. Psychometric scales were administered to evaluate cognitive functioning (Syndrom Kurztest), depressive symptomatology (Montgomery-Asberg Depression Rating Scale), posttraumatic stress symptoms (Posttraumatic Stress Syndrome 10-Questions Inventory) and HRQOL (SF-36 Health Status Questionnaire). Delirium Rating Scale (DRS) was used daily over the course of intensive care unit treatment. Postoperative delirium developed in 11 of the 34 patients (mean DRS rating scale score+/-S.D.: 20.36+/-6.22, range: 14-31). Short-term consequences of cardiac surgery included adjustment disorder with depressed features (n=11), posttraumatic stress disorder (n=6), major depression (n=6) and clinically relevant cognitive deficits (n=13). At 12 months, the severity of depression and anxiety disorders improved and returned to the preoperative level, and 6 out of the 30 followed-up patients displayed cognitive deficits. Our patients' HRQOL SF-36 self-reports significantly improved compared with baseline quality of life data. However, 1-year overall lower cognitive function scores were associated with lower HRQOL. Cardiac surgery with CPB is associated with improvements in HRQOL relative to the preoperative period, but the presence of cardiac surgery-related cognitive decline impairing HRQOL is a complication for a subgroup of cardiac surgical patients in the long-term outcome.

[Psychosocial screening and selection of candidates for liver transplantation].

281 consecutive candidates for liver transplantation were referred to our consultation-liaison service for psychiatric evaluation over a 4-year period. For these candidates a semistructured psychiatric interview according to the codes listed in the DSM-III-R and the Transplant Evaluation Rating Scale (TERS) classifying patients' level of adjustment in psychosocial functioning were completed. Our study showed a prevalence rate of psychiatric disorders of 65.8 % among candidates. The categories of alcohol abuse (27.8 %) and alcohol dependence (11.7 %) were the most frequent psychiatric diagnoses. The mean TERS summary score of the whole sample was 33.38 +/- 7,31. 68.4 % of the sample were considered good candidates, 18.1 % of the candidates were identified borderline, but acceptable under some conditions, and 13.5 % of the referrals were rated poor liver transplant candidates. The TERS summary scores discriminated well between the three rating categories of candidate quality. Apart from a careful assessment of psychiatric morbidity including substance abuse disorders, the C-L psychiatrist should always rate psychosocial functioning referring to coping, compliance, social support and lifestyle factors among liver transplant candidates. The TERS therefore may be used routinely.
