[Gender aspects in female and male physicians : Occupational and psychosocial stress]. / Gender-Aspekte bei Ärztinnen und Ärzten : Berufsleben und psychosoziale Belastungen.

BACKGROUND: International studies have shown that physicians have an elevated risk of developing depression or burnout syndrome. Gender aspects with regard to occupation are discussed in German politics and society. Currently, there is little data comparing female and male physicians with regard to stress at work, depression, and burnout. OBJECTIVES: Are there differences between male and female physicians with respect to psychosocial strain, emotional exhaustion, and depression? METHODS: In different cross-sectional studies, anaesthetists, psychiatrists and dentists filled out a questionnaire containing questions on personal data, occupation, past medical history and medication intake. Additional standardized questionnaires (Beck Depression Inventory (BDI) and Maslach Burnout Inventory (MBI)) were performed. RESULTS: The return rate was 51.8 % (n = 3782). Male and female physicians vary significantly in social data, participation in the job, and health status. Female physicians are on average not married (p < 0.001) and have significantly fewer children (p < 0.05). Leading positions are mostly held by male physicians (p < 0.001); female physicians more often work in part-time jobs (p < 0.001). Female physicians reached higher scores of emotional exhaustion (MBI) (p < 0.01) and depression (BDI) (p < 0.001). DISCUSSION: The study shows big differences between male and female physicians with respect to their occupation, personal life, and psychosocial wellbeing. Female physicians more often report burnout and depression. Causes might be family and job strain, gender aspects in hierarchy, as well as different recognition and interpretation of symptoms.

Risk of bleeding related to selective and non-selective serotonergic antidepressants: a case/non-case approach using data from two pharmacovigilance databases.

INTRODUCTION: There is increasing evidence for an association between treatment with selective serotonin reuptake inhibitors (SSRI) and an increased risk of bleeding events. The most important underlying mechanism appears to be inhibition of serotonin uptake in platelets, an effect that is also present in antidepressants with non-selective serotonin-reuptake inhibition (NSRI). Accordingly, also NSRI may be associated with an increased risk of bleeding. However, there is little data in this regard. METHODS: Based on data (spontaneous reports of adverse drug reactions) from 2 pharmacovigilance databases (WHO-database/Vigibase™; BfArM/AkdÄ-database in Germany) we used a case/non-case approach and calculated reporting odds ratios (ROR) as measures for disproportionality regarding the association of treatment with an agent of the group SSRI/NSRI and haemorrhages. RESULTS: Whereas both positive control agents (ASS and diclofenac) were statistically associated with haemorrhages in both databases (ASS: BfArM/AkdÄ, ROR 13.62 [95% CI 12.76-14.53]/WHO, ROR 12.96 [95% CI 12.75-13.16]; diclofenac: BfArM/AkdÄ, ROR 3.01 [95% CI 2.71-3.21]/WHO, ROR 2.11 [95% CI 2.05-2.16]), none of the agents of the group SSRI (ROR<1) was associated with haemorrhages. In group NSRI, only St. John's wort/hypericum was associated with haemorrhages (WHO-database, ROR 1.31 [95% CI 1.06-1.63]). DISCUSSION: Signal detectioning in 2 pharmacovigilance databases suggest that serotonin reuptake inhibition is not associated with an increased risk of bleeding. However, underreporting may have accounted for the evaluated absent associations, particularly concerning SSRI. Regarding the detected increased risk of bleeding associated with hypericum, pharmacokinetic drug-drug interactions may be relevant independent of serotonin reuptake inhibition.

[Optical Coherence Tomography (OCT)--a new diagnostic tool in psychiatry?]. / Optische Kohärenztomografie (OCT)--ein neues diagnostisches Instrument in der Psychiatrie?

Optical coherence tomography (OCT) is a non-invasive, contact-less imaging method which provides an "in vivo" representation of the retina. It allows the quantitative measurement of retinal nerve fibre layer thickness (RNFLT) and macula thickness (MT) and, in addition, is suitable to measure volumes (e.g., macula volume/MV). In the research of neurodegenerative diseases, OCT has been increasingly used and has shown its potential as a possible diagnostic tool over the course of the last few years. In recent years, the hypothesis that mental disorders like schizophrenia or unipolar depressive disorder have a degenerative component was established through a variety of volumetric MRI studies. This review article aims to present the method of OCT, to display its recent use in medicine and psychiatry, as well as to examine possible additional applications in the field of psychiatry.

[Animal hoarding: a mental disorder with implications for public health]. / Animal Hoarding: eine psychische Störung mit Implikationen für die Öffentliche Gesundheit.

Animal hoarding (AH) is a mental disorder that is characterised by an excessive number of kept animals, inability to maintain minimal standards of animal care and hygiene, and deficient insight into the thereby developing failures and problems. Although AH as a disease concept is neither represented in the DSM-5 nor the ICD-10, it may be classified as a subform of the hoarding disorder (DSM-5 300.3) that was implemented in the DSM-5 as an obsessive-compulsive disorder. Due to the hygienic deficiencies of the living spaces and the insufficient keeping of animals there is an increased risk of epizootic diseases and zoonoses. Specific epidemiological studies do not exist, however, women seem to be affected more frequently. AH is diagnosed mostly in late adulthood. Besides thorough somatic and psychiatric medical diagnostics, cooperation with the veterinary offices and authorities is usually necessary. Comorbid mental disorders (particularly depressive, obsessive-compulsive and personality disorders) are frequent. Currently, no evidence-based therapies exist. Social therapy and cognitive-behavioural psychotherapeutic interventions as well as sufficient treatment of comorbid mental disorders are recommended.

[Botulinum toxin for the treatment of major depressive disorder]. / Botulinumtoxin bei der Behandlung depressiver Störungen.

OBJECTIVE: Botulinum toxin (BTX) plays an important role in the treatment and prophylaxis of migraine and is also used for the treatment of focal dystonia, spasm, hypersalivation, and hyperhydrosis. Recent clinical trials suggest that BTX treatment of muscles involved in the development of negative emotions may also have an antidepressant effect. This article gives a systematic review of the literature regarding BTX in the treatment of major depression. METHODS: We screened the databases of Medline and Scopus using the search terms [("botulinum toxin" OR "botox") AND ("antidepressant" OR "depression" OR "depressed")]. The website www.clinicaltrials.gov was screened with the same search terms in order to detect current studies. RESULTS: As of April 2013, we identified 3 studies that evaluated the antidepressant effects of BTX in the treatment of major depression. An improvement in mood after treatment with BTX was seen in a case series of 10 depressed patients. In a randomised, placebo-controlled study of thirty patients assigned to a verum (BTX, n = 15) or placebo (saline, n = 15) group, treatment with BTX has also shown a positive effect on mood. Another prospective, open-label study evaluated the antidepressive effect of BTX in 25 subjects with major depression. On www.clinicaltrials.gov we identified 2 ongoing studies, which are currently investigating the antidepressant effect of BTX. CONCLUSION: Recently published studies have shown a reduction of depressive symptoms after treatment of the glabellar frown lines with BTX injections. Further clinical studies in larger patient samples are necessary to prove the efficacy and safety of BTX injections used for the treatment of depressive disorders.

Agomelatine and hepatotoxicity: implications of cumulated data derived from spontaneous reports of adverse drug reactions.

Considering the antidepressant agomelatine (AGM) there is a discrepancy between the widespread knowledge of the potential of AGM to cause hepatotoxic adverse drug reactions (ADR) and the availability of corresponding published data. This impedes an adequate assessment of the hepatotoxicity profile of AGM. We conducted a query of the database of a German Medical Regulatory Body (BfArM) and analyzed spontaneous reports of hepatotoxic ADR. We identified n=58 cases of AGM-related hepatotoxic ADR. Most frequent ADR was asymptomatic increase of liver enzymes (79%); n=6 patients (10%) with AGM-related toxic hepatitis were reported. Characteristics of patients: female sex (69%), age > 50 years (mean 54 years), polypharmacy (57%), and presence of cardiovascular risk factors (58.5%). Most of the hepatotoxic ADR (90%) were reported to have improved/recovered after discontinuation of AGM. Our evaluation suggests that AGM features a potential to cause severe forms of hepatotoxicity and emphasizes that a pre-existing liver disease is a contraindication for treatment with AGM. Secondly, increased age, female sex and polypharmacy may be risk factors for the development of AGM-related hepatotoxic ADR.

[Succinic semialdehyde dehydrogenase deficiency: an inheritable neurometabolic disease]. / Succinat-Semialdehyd-Dehydrogenase-Mangel: eine vererbbare neurometabolische Erkrankung.

Succinic semialdehyde dehydrognase deficiency (SSADHD) is a neurometabolic disease with autosomal recessive inheritance. Although only about 450 cases are known worldwide, SSADHD is a frequent paediatric disorder of the neurotransmitter metabolism. SSADHD is caused by a mutation of the Aldh5a1-gene resulting in a dysfunction of the enzyme succinic semialdehyde dehydrogenase. This is followed by an accumulation of γ-aminobutyric acid and succinic semialdehyde that is alternatively metabolised via succinic semialdehyde reductase to γ-hydroxybutyric acid. The clinical phenotype is unspecific with pronounced interindividual variability. However, delayed acquisition of motor and language developmental milestones as well as epilepsy, mental retardation, sleep disorder, ataxia, muscle hypotonia, and behavioural disturbances are frequent. First symptoms frequently occur in the first year of life while the general course of the disease is non-progressive. Currently, no causal therapy exists.

[Liquid ecstasy in general psychiatry: a case series]. / Liquid ecstasy in der allgemeinpsychiatrie: eine fallserie.

BACKGROUND: In emergency medicine and anesthaesiology liquid ecstasy (LE), the street name for GHB, GBL or 1,4-B, has become infamous for causing severe intoxications and withdrawal. In general psychiatry, however, it is little known. Therefore, we set out to gather data about the role of LE in general psychiatry, typical users and common clinical problems associated with the use of LE. METHODS: We retrospectively identified and studied all patients with a reported the use of LE seen at the Department of Psychiatry, University of Ulm, Germany, between 1998 and 2011. RESULTS: In 14 years, 19 users of LE were identified, the first dating from 2005. The majority reported a use of GBL (63 %), GHB was less common, and 1,4-B was not reported. Patients were predominantly young men (median age 25 years, 79 % men) with a history of multiple substance abuse. Ten patients had only a former use of LE, the other nine patients used it at the time of presentation. Of these, every third patient had to be transiently treated in an intermediate care unit, usually because of very severe and sudden withdrawal symptoms. Otherwise, detoxification was possible in psychiatry, but often required high doses of benzodiazepines. Three patients met the criteria for dependence from GBL. CONCLUSIONS: In recent years, a small number of users of LE is seen also in general psychiatry, The problem is rather the severity of withdrawal than the number of cases. Close cooperation with intermediate care units is needed. In any case of coma of unknown origin or delirium with sudden onset LE use or withdrawal has to be taken into consideration, respectively. Many clinical problems result from the fact that LE cannot be detected in routine drug screenings. According to our experience, withdrawal from LE can be controlled with benzodiazepines.

Withdrawal and discontinuation phenomena associated with tranylcypromine: a systematic review.

Tranylcypromine (TCP) is an effective antidepressant with a complex pharmacological profile and a relevant risk of abuse and dependence. Withdrawal phenomena (WP, in the case of TCP-abuse/dependence) or discontinuation phenomena (DP, in the case of absent TCP-abuse/dependence) subsequent to abrupt termination of TCP are a potentially severe clinical syndrome. We conducted a systematic review of all previously published WP/DP cases following abrupt termination of TCP in order to identify typical clinical presentations and risk factors of WP/DP and frequency of TCP abuse or dependence within these patients. By searching the Medline and Scopus databases we identified n=25 cases (cohort WP: n=18, cohort DP: n=7). Delirium was found in n=13 patients (cohort WP: 10/55.6%; cohort DP: 3/42.9%), n=6 demonstrated WP/DP without delirium (WP: 6/33.3%; DP: 0/0%) and n=5 rapid relapse in depression (WP: 1/5.6%; DP: 4/57.1%). Mean time until development of WP/DP was 1.9 (WP) and 2.2 (DP) days. Mean duration of WP/DP was 5.7 (WP) and 11.3 (DP) days. All patients of cohort WP were described to feature TCP-abuse/dependence. Patients with delirium were on average older (41.8 years vs. 37.8 years) and featured higher mean prescribed (71.0 mg vs. 38.3 mg) and actually taken daily TCP dosages (285.8 mg vs. 187.7 mg). In conclusion, even termination of lower daily dosages of TCP may result in delirium. Thrombocytopenia features diagnostic value in patients with deliria of unknown etiology. TCP should be administered with great care, especially in dependence-prone patients.·

Aseptic gingivitis related to quetiapine hemifumarate.

Quetiapine hemifumarate (QF) is widely used in psychiatry and is associated with regularly occurring side effects such as dizziness and metabolic problems. Apart from these typical adverse events the agent has attracted attention for several rare phenomena (priapism, cholestasis, rhabdomyolysis) that indeed feature anecdotal character, but are nevertheless indispensable for a comprehensive understanding of the factual risk profile of quetiapine. We present the first report of aseptic gingivitis associated with QF in a patient with mental retardation.

Non-fatal and fatal liver failure associated with valproic acid.

Little is known about hepatotoxicity associated with valproic acid (VPA), a widely used substance in neuropsychiatry.All reported cases to the German Federal Institute for Drugs and Medical Devices between 1993 and 2009 of VPA-induced serious hepatic side effects were evaluated.A total of 132 cases of serious VPA-associated liver failure were identified. Approximately one third (34.8%) occurred under VPA monotherapy, while the majority was seen with VPA plus co-medication, most frequently antiepileptics (34.8%) and benzodiazepines (16.7%). A subgroup of 34 cases (25.8%) had a fatal outcome, the largest number reported to date. Of these, 32.4% were under VPA monotherapy and 67.6% under VPA plus concomitant medication. Within the study period a significant increase in the total number of reported cases and the subgroup of fatal cases was found.This first pharmacovigilance study of VPA-associated liver failure indicates a higher rate of non-fatal and fatal liver failure when VPA is given with co-medication as compared to monotherapy. However, co-medication per se does not increase the risk of fatalities.

Delusional infestation and the specimen sign: a European multicentre study in 148 consecutive cases.

BACKGROUND: Systematic studies of delusional infestation (DI), also known as delusional parasitosis, are scarce. They lack either dermatological or psychiatric detail. Little is known about the specimens that patients provide to prove their infestation. There is no study on the current presentation of DI in Europe. OBJECTIVES: To determine the number of true infestations, to assess with which pathogens patients believe themselves to be infested, and to gather details about the frequency and nature of the specimens and the containers used to store them, based on European study centres. METHODS: Retrospective study of consecutive cases with suspected DI from six centres (Dermatology, Psychiatry, Tropical Medicine) in four European countries (U.K., Germany, Italy, France). RESULTS: In total, 148 consecutive cases of suspected DI were included, i.e. the largest cohort reported. None of the patients had evidence of a genuine infestation, as shown by examinations by dermatologists and/or infectious disease specialists. Only 35% believed themselves to be infested by parasites; the majority reported a large number of other living or inanimate (17%) pathogens. Seventy-one patients (48%) presented with what they believed was proof of their infestation. These specimens were mostly skin particles or hair, and rarely insects (only very few of which were human pathogenic or anthropophilic, and none of these could be correlated with the clinical presentation), and only 4% were stored in matchboxes (three of 71). CONCLUSIONS: This first multicentre study of DI in Europe confirms that the term 'delusional infestation' better reflects current and future variations of this entity than 'delusional parasitosis'. The presentation of proofs of infestation, commonly referred to as 'the matchbox sign', is typical but not obligatory in DI and might better be called 'the specimen sign'.

Successful treatment of major depression with electroconvulsive therapy in a pregnant patient with previous non-response to prefrontal rTMS.

The treatment of psychiatric disorders during pregnancy poses a challenge particularly regarding limited pharmacological possibilities. Repetitive transcranial magnetic stimulation (rTMS) and electroconvulsive therapy (ECT) have been described to be successful in single cases, however, guidelines are lacking. In order to contribute to the pool of empirical data that is necessary to create evidenced-based recommendations we present a case of successful treatment of major depression with ECT in a pregnant patient with previous non-response to rTMS.

Transcranial magnetic stimulation in depression--lessons from the multicentre trials.

Looking at novelties and advances in medicine in particular in the treatment of major depressive disorder no principally new antidepressant treatment strategy has been established in clinical routine in the last fifty years. However, regarding the considerable issue of treatment resistance in depression, new therapeutic strategies are urgently required. In this context, repetitive transcranial magnetic stimulation above the dorsolateral prefrontal cortex has been proposed as a potential new treatment option for depression; furthermore, in October 2008 a first rTMS-device (NeuroStar TMS Therapy System) was approved by the FDA for the treatment of treatment resistant major refractory depression in adults. Yet, despite now nearly two decades of research in this field, no final answer concerning its validity for antidepressant treatment in the clinical practice is given. Numerous studies with small sample sizes and heterogeneous designs have been performed in this field yielding to different results. These were subjected to meta-analyses, assessing the antidepressant effect of rTMS, which are briefly summarized in this article. Further, multicentre-trials with larger numbers of patients were performed, which are presented and critically discussed here in more detail. This short review shall thus provide an overview of the current status of knowledge concerning rTMS in depression and it also provides some recommendations for future research in this field.

Delusional infestation in dermatology in the UK: prevalence, treatment strategies, and feasibility of a randomized controlled trial.

BACKGROUND: Delusional infestation (DI) is considered rare, but true epidemiological studies are only available for Germany. Patients usually contact dermatologists, and psychiatric referral is often impossible. AIM: To estimate the prevalence of DI in UK dermatology clinics, to examine the feasibility of a multicentre randomized controlled trial (RCT) in dermatology, and to evaluate the psychopharmacotherapy of DI in dermatology. METHODS: A short questionnaire survey was distributed to 231 UK dermatologists, asking how many new and ongoing patients with DI they had seen in the past 3 years, which treatments they had used, and whether they thought an RCT would be feasible. RESULTS: The return rate was good (44.6%, n=103 of 231). In total, 103 British dermatology consultants reported 182 cases seen over the past 3 years and 54 current cases. The 3-year prevalence of DI in dermatology outpatients was 4.99 per million; the point prevalence was 1.48 per million. Around a third (35%) of patients were prescribed psychotropic medication, mostly pimozide. Respondents were evenly split in their view of the feasibility of organizing an RCT of treatment of DI. CONCLUSIONS: Our survey covers more than half of the UK population, allowing the first estimate of basic epidemiological data on DI in dermatology in the UK. Our prevalence estimates indicate that DI is not as rare an illness in dermatological practice as previously assumed. There are potential difficulties in organizing an RCT of DI treatment. British dermatologists do not regularly use second-generation antipsychotics as their first choice of treatment.
