[Prevalence of sleep-related breathing disorders of inpatients with psychiatric disorders]. / Prävalenz schlafbezogener Atmungsstörungen bei stationären Patienten mit psychischen Erkrankungen.

BACKGROUND: Sleep-related breathing disorders seriously impair well-being and increase the risk for relevant somatic and psychiatric disorders. Moreover, risk factors for sleep-related breathing disorders are highly prevalent in psychiatric patients. The aim of this study was for the first time in Germany to study the prevalence of obstructive sleep apnea syndrome (OSAS) as the most common form of sleep-related breathing disorder in patients with psychiatric disorders. METHODS: In 10 psychiatric hospitals in Germany and 1 hospital in Switzerland, a total of 249 inpatients underwent an 8­channel sleep polygraphy to investigate the prevalence of sleep apnea in this group of patients. RESULTS: With a conspicuous screening result of 23.7% of the subjects, a high prevalence of sleep-related breathing disorders was found to occur among this group of patients. Male gender, higher age and high body mass index (BMI) were identified as positive risk factors for the detection of OSAS. DISCUSSION: The high prevalence indicates that sleep apnea is a common sleep disorder among psychiatric patients. Although OSAS can lead to substantial disorders of the mental state and when untreated is accompanied by serious somatic health problems, screening procedures are not part of the routine work-up in psychiatric hospitals; therefore, sleep apnea is presumably underdiagnosed in psychiatric patients. In view of the results of this and previous studies, this topic complex should be the subject of further research studies.

[Specialist Training in Psychiatry and Psychotherapy : Evaluation of the East Westphalia-Lippe Academy curriculum]. / Facharztweiterbildung Psychiatrie und Psychotherapie : Evaluation des Curriculums eines Weiterbildungsverbunds in Ostwestfalen-Lippe.

BACKGROUND: Despite of the undisputed impact of education quality on becoming a specialist in psychiatry and psychotherapist, systematic studies in this field do not exist in Germany, apart from the evaluation of practical education by the medical councils. MATERIALS AND METHODS: The Akademie-OWL, an education union of psychiatric clinics in the East Westphalia region of Germany, has provided 12-item questionnaire-based routine evaluations of theoretical education seminars since 2009. Seminars are held by consultants of psychiatry and psychotherapy within six separate weeks over a period of four years. All lecturers receive feedback from the evaluation. The results of this ongoing evaluation are presented using a typical example and in an aggregated format as a time series on the basis of one global item. RESULTS: The data show that (1) the full range of a five-point Likert scale is used by the candidates, (2) psychiatric competences of the lecturers are more positively evaluated than their didactic competences, (3) neither within the four-years period of psychiatric education nor between different generations of candidates are systematic changes of evaluation results observed, and (4) minor to moderate differences of evaluation were observed between the different thematic fields of psychiatry and psychotherapy. DISCUSSION: These results indicate the need of more systematic education research on establishing valid and reliable specific instruments as well as the need of systematic training of didactic competences of teaching consultants.

[Computer-assisted treatment pathway for schizophrenia. Development and initial experiences]. / EDV-gestützter Behandlungspfad für Schizophrenie. Pfadentwicklung und erste Erfahrungen.

Standardization in psychiatry is a developmental process which, following on from psychopathology and nosology is now increasingly affecting the field of treatment. The development of guidelines for the treatment of psychiatric diseases has now become well accepted, although the impact on routine practice is still limited. Treatment pathways bring recommendations from guidelines into a clear and practice-oriented algorithm. The prerequisite for this is the inclusion of all aspects and elements of the treatment as well as all professions involved in the treatment and a valid electronic data processing foundation. Such an approach is presented here with the example of the development and implementation of a clinical pathway for inpatients with schizophrenia. Initial results revealed that patients who received multi-professional treatment within such a clinical pathway, improved better than patients of the control group, as measured by CGI, PANSS and PSP. This shows that introduction of a clinical pathway leads to an improvement of treatment quality. Standardization of psychiatric treatment processes could be highly relevant in respect to the new remuneration system for psychiatry in Germany.

Influence of levothyroxine in augmentation therapy for bipolar depression on central serotonergic function.

INTRODUCTION: Adjunctive treatment with supraphysiological doses of levothyroxine (L-T4) in bipolar depression shows promise, but the neurobiological mechanisms underlying clinical improvement are unknown. It has been postulated from animal studies that exogenous thyroid hormones may exert their modulatory effects in patients with affective disorders via an increase in serotonergic neurotransmission. Therefore, we investigated the loudness dependence of auditory evoked potentials (LDAEP) as a measure of central serotonergic activity and response to L-T4. METHODS: This 6-week, double-blind, randomized, placebo-controlled study assessed the efficacy of L-T4 adjunctive to continuing treatment with mood stabilizer and/or antidepressant medication in 20 patients with bipolar depression. LDAEP was assessed before and after treatment with L-T4. RESULTS: Scores of the Hamilton Depression Rating Scale and Montgomery Asberg Depression Rating Scale decreased significantly during the study. There was no difference in pre- and post-treatment LDAEP between the groups, and no correlation between LDAEP and psychometric measures in the course of the study. DISCUSSION: The hypothesis of a relationship between response of augmentation therapy with levothyroxine in bipolar depression and serotonergic activity could not be confirmed.

[Sleep disturbances and suicidality: relationships and clinical implications]. / Schlafstörungen und Suizidalität: Zusammenhänge und klinische Bedeutung.

Besides several risk factors for suicide, there is a recent increase in clinical and epidemiological studies pointing to a potential relationship between sleep loss or sleep disturbances and suicidality. This work, based on a systematic literature research, gives an overview on the findings of relationships between suicidality (i. e., suicidal thoughts, suicide attempts, suicides) and sleep disturbances, especially insomnia, nightmares, but also hypersomnia and nocturnal panic attacks. There is evidence that sleep disturbances in suicidal insomniacs with comorbid psychiatric disorder are independently predictive for suicidality, too. Shared aspects of pathogenesis of the two entities and therapeutic options are also discussed. Recognition of sleep disturbances is essential for suicide prevention in clinical practice.

[On the role of pharmacists in the care of patients with depressive disorders--evaluation of a training programme for pharmacists]. / Zur Rolle der Apotheker in der Versorgung depressiver Patienten--Evaluation eines Fortbildungsprogramms für Pharmazeuten.

Depressive disorders are highly prevalent, under-diagnosed and under-treated, causing high direct and socioeconomic costs. So far, the role of pharmacists in counselling and supervision of patients with depression has hardly been investigated. However, as pharmaceutical experts for doctor's prescriptions as well as self-medication, they represent an important multiplicator group in health care systems. The aim of nationwide seminars for pharmacists was to improve attitudes and knowledge of the spectrum of depressive disorders. The evaluation (n=102) which was performed within the seminars shows that personal beliefs of pharmacists regarding depression depend on their own age and years of professional experience. The study points out that specific training programmes (e. g., communication techniques), especially in a subgroup of younger and less experienced staff members in the pharmacy, may improve the care of depressive individuals. This should--in close cooperation with general practitioners, mental health specialists and health care systems--also substantially contribute to enhance effectiveness of treatment of depressive disorders and to reduce healthcare costs.

Moderate physical exercise: a simplified approach for ventricular rate control in older patients with atrial fibrillation.

AIMS: This prospective pilot-study was performed to assess whether regular moderate physical activity elevates the parasympathetic tone to the atrio-ventricular node and decreases VR during permanent AF. BACKGROUND: Adequate ventricular rate (VR) control in patients with permanent atrial fibrillation (AF) is not easy to accomplish. METHODS: 10 patients (mean age 59 +/- 10 years) with permanent AF (duration: 10 +/- 8 years) underwent moderate physical exercise adjusted to their individual physical capability (45 min walking/jogging twice a week). To analyze VR control physical exercise tests and Holter-ECG recordings were performed before and after 4 months. In addition, stepwise lactate tests and psycho-pathometric examinations were obtained. RESULTS: After 4 months of training, there was a trend toward a decrease of mean VR in 24 h Holter-ECGs by 12% from 76 +/- 20 to 67 +/- 12 bpm (P = 0.05) while there was no significant decrease of the minimal VR (38 +/- 8 vs. 36.3 +/- 4.5 bpm, P = 0.54). At a lactate threshold of 2 mmol/l there was a trend towards an increase of the running speed from 105 +/- 11 to 116 +/- 12 m/min (P = 0.05). A significant VR decrease of 8% (range 5-10%) was observed at almost all exercise levels during exercise treadmill testing. Increases of exercise capacity and decreases of VR were accompanied by subjective improvements of health perception. CONCLUSION: Regular moderate physical activity decreases VR at rest and during exercise while increasing exercise capacity. Physical training should be taken into account for ventricular rate control during AF.

[Monoaminergic function in major depression. A possibly helpful tool for choosing treatment strategy]. / Monoaminerge Funktion bei depressiven Patienten. Eine Hilfe bei der Wahl der Behandlungsstrategie?

Little is known about the variables that might predict outcome in major depression. Most studies do not imply any clinical consequences for treatment because their predictors were nonspecific and results did not differ between the different treatment options. Finding a variable that can predict the antidepressive treatment option best suited to an individual might help in reducing the considerable number of nonresponders in the treatment of depression. As most antidepressants influence the serotonergic or noradrenergic system, monoaminergic function at the start of therapy might be a possible specific response predictor. In this review, measures that can determine monoaminergic function are presented along with their relationship to treatment response, e.g., monoaminergic metabolites, neuroendocrine challenge tests, evoked event-related potentials, genetics, and neuroimaging. In conclusion, the results of serotonergic functions are still heterogeneous, but the relationship between noradrenergic function and treatment response has not been investigated in any detail yet.

[Cognitive impairment after accidental high-dose corticosteroid therapy]. / Kognitive Störungen nach akzidenteller hoch dosierter Kortisontherapie.

Synthetic glucocorticosteroids can induce various severe mental disorders. Persisting cognitive disorder represents a rare complication of corticoid therapy involving memory, concentration, attention, or occupational performance. We observed the effects of a 20-day self-induced high-dose corticosteroid treatment on the cognitive functions in a 54-year-old patient. Having excluded dementia due to other organic causes, we examined the patient neuropsychologically immediately at the end of the steroid therapy and at follow-up (1, 2, 4, and 6 months). The initial tests showed seriously impaired functioning of concentration, attention, learning, and memory as well as of common ability to solve problems. The follow-up tests up to 6 months revealed an improvement of concentration and attention, but there were still serious deficits of the declarative memory with a high confabulating tendency. Our results confirm those of human experimental studies that exogenous steroids can cause serious persisting specific cognitive disorders especially of the declarative, hippocampus-dependent memory.

[Stalking: problems in differentiation between aberrant social behaviour and mental disorders]. / Stalking: Probleme bei der Differenzierung zwischen sozialer Auffälligkeit und psychischer Störung.

The concept "stalking" refers to willful, malicious, and repeated following or harassment of another person that threatens her or his security. Although there is nothing new about the occurrence of this conduct it has been discussed in psychiatry more intensely in recent years. As a result there are a few attempts at classification, without any claim of general validity. Patterns of stalking behaviour reflect a wide spectrum from aggressive actions in the course of conflicts in a relationship to schizophrenia. Thus, it is not adequate to classify this as a psychiatric disorder per se. Thorough diagnostic assessments are mandatory before introducing legal measures, whereas if these are omitted, the term "mental disorder" may be inappropriately used in a wider sense. This may entail unfavourable consequences to be discussed in this paper.

Ping-pong gaze in combined intoxication with tranylcypromine, thioridazine, and clomipramine.

OBJECTIVE: This paper reports the occurrence of ping-pong gaze, a neuro-ophthalmological syndrome usually related to severe structural brain damage, in a patient intoxicated with tranylcypromine, thioridazine, and clomipramine. BACKGROUND: Although there have been some reports about the occurence of Ping-pong gaze after intoxications, it is usually related to severe bilateral hemispheric brain damage following stroke or traumatic injuries. METHOD: We report the case of a 56-year old woman who developed a neurotoxic syndrome with coma, hyperthermia, muscular rigidity, myoclonic jerks and tachycardia following an intoxication. Additionally rhythmic and pendular conjugate horizontal eye movements could be observed for three days, so that the diagnosis of ping-pong gaze was made. RESULTS: A treatment with dantrolene lead to complete remission of the neurotoxic syndrome with no signs of neurological or physical deficits. At the stage of regaining consciousness the eye movements became normal. CONCLUSION: In our case the combined intoxication with an monoamine oxidase inhibitor, a neuroleptic and a tricyclic agent lead to a neurotoxic syndrome and the occurrence of a rare neuro-ophthalmological syndrome usually related to bilateral hemispheric brain dysfunction.

High intensity dependence of auditory evoked dipole source activity indicates decreased serotonergic activity in abstinent ecstasy (MDMA) users.

Neurotoxic damage of central serotonergic systems has been demonstrated in numerous animal studies after exposure to methylenedioxyamphetamines (ecstasy). A high intensity dependence of auditory evoked potentials and, particularly, of the tangential N1/P2 source activity has been associated with low levels of serotonergic neurotransmission in humans. We performed an auditory evoked potentials study in 28 abstinent recreational ecstasy users and two equally sized groups of cannabis users and nonusers. The ecstasy users exhibited an increase of the amplitude of the tangential N1/P2 source activity with higher stimulus intensities; whereas, both control groups failed to exhibit this feature. These data are in line with the hypothesis that abstinent ecstasy users present with diminished central serotonergic activity. This feature of information processing is probably related to the well-recognized neurotoxic potential of ecstasy. Our data indicate that recreational ecstasy use may cause long-term alterations in the function (and possibly structure) of the human brain.
