Clinician treatment choices for post-traumatic stress disorder: ambassadors survey of psychiatrists in 39 European countries.

BACKGROUND: Considering the recently growing number of potentially traumatic events in Europe, the European Psychiatric Association undertook a study to investigate clinicians' treatment choices for post-traumatic stress disorder (PTSD). METHODS: The case-based analysis included 611 participants, who correctly classified the vignette as a case of PTSD, from Central/ Eastern Europe (CEE) (n = 279), Southern Europe (SE) (n = 92), Northern Europe (NE) (n = 92), and Western Europe (WE) (N = 148). RESULTS: About 82% woulduse antidepressants (sertraline being the most preferred one). Benzodiazepines and antipsychotics were significantly more frequently recommended by participants from CEE (33 and 4%, respectively), compared to participants from NE (11 and 0%) and SE (9% and 3%). About 52% of clinicians recommended trauma-focused cognitive behavior therapy and 35% psychoeducation, irrespective of their origin. In the latent class analysis, we identified four distinct "profiles" of clinicians. In Class 1 (N = 367), psychiatrists would less often recommend any antidepressants. In Class 2 (N = 51), clinicians would recommend trazodone and prolonged exposure therapy. In Class 3 (N = 65), they propose mirtazapine and eye movement desensitization reprocessing therapy. In Class 4 (N = 128), clinicians propose different types of medications and cognitive processing therapy. About 50.1% of participants in each region stated they do not adhere to recognized treatment guidelines. CONCLUSIONS: Clinicians' decisions for PTSD are broadly similar among European psychiatrists, but regional differences suggest the need for more dialogue and education to harmonize practice across Europe and promote the use of guidelines.

The complex presentation of carcinomatous meningitis / A meningitis carcinomatosa komplex megjelenése.

Összefoglaló. Az emlotumor miatt kezelt, majd gondozott beteget - több tünetmentes év után - fejfájás, szédülés, ataxia, megváltozott, furcsa viselkedés, emlékezetzavar és dezorientáció miatt neurológiai, majd belgyógyászati osztályokon vizsgálták. Az alapos kivizsgálás ellenére a tüneteit magyarázó organikus eltérést nem igazoltak, ugyanakkor már a kezdetektol felmerült a szomatizációs tünetképzés lehetosége, ezért pszichiátriai osztályos felvételére került sor. Az elvégzett vizsgálatok, illetve a klinikai kép regresszív állapotot valószínusítettek. Terápiás próbálkozásaink ellenére a páciens állapota romlott, végül a megismételt neurológiai vizsgálatok meningitis carcinomatosát igazoltak. Az esettel szemléltetni kívánjuk, hogy a beteg premorbid muködési nívója, személyiségstruktúrája hogyan képes befolyásolni az ellátószemélyzetet, milyen külso és belso konfliktusokat válthat ki. A diagnózishoz vezeto folyamat bemutatásával fel kívánjuk hívni a figyelmet az interdiszciplináris együttmuködés fontosságára. Orv Hetil. 2021; 162(43): 1744-1748. Summary. Our patient with known breast cancer in her past medical history was hospitalized - after several asymptomatic years - for headache, dizziness, ataxia, changed behaviour and disorientation. Thorough internal and neurologic investigations did not find any disease underlying her symptoms, therefore the possibility of somatization disorder was raised. Despite lege artis therapeutic interventions carried out on the psychiatry ward, the patient's condition deteriorated and repeated neurological examinations eventually revealed carcinomatous meningitis. With this case, we would like to illustrate how the patient's premorbid function level and personality features might influence the attitude and opinion of the health care personnel, and what kind of external and internal conflicts might be triggered. By presenting the complexity of the diagnostic work-up, we would like to emphasize the importance of interdisciplinary cooperation in the interest of our patients.

A Real-World, Prospective, Multicenter, Single-Arm Observational Study of Duloxetine in Patients With Major Depressive Disorder or Generalized Anxiety Disorder.

Background: Suboptimal treatment response during anti-depressive treatment is fairly common with the first antidepressant (AD) choice, followed by switching to another agent in the majority of cases. However, the efficacy of this strategy over continuation of the original agent is less solidly documented in real-life studies. The aim of our present study was to ascertain the effects of switching to duloxetine following inadequate response to prior ADs on general illness severity, pain, and health-related quality of life in a large sample of major depressive disorder (MDD) and generalized anxiety disorder (GAD) patients in a prospective, real-world, multicenter, observational study. Methods: A total of 578 participants with MDD or GAD were enrolled in 58 outpatient sites in an 8-week, single-arm, open-label, flexible-dose trial with duloxetine. Severity of symptoms [with Clinical Global Impression-Severity (CGI-S) and Clinical Global Impression-Improvement (CGI-I)], severity of pain (with a Visual Analog Scale), satisfaction with current treatment, and health-related quality of life [with the three-level version of the EuroQol five-dimensional questionnaire (EQ-5D-3L)] measures were recorded at baseline and at follow-up visits 4 and 8 weeks after initiation of treatment. Data were analyzed using ANOVA and mixed linear models. Results: 565 patients completed the study and comprised the analyzed dataset. Results indicated that severity of illness significantly decreased over the 8 weeks of the study and already at 4 weeks in both patient groups. Overall quality of life and all of its subindicators also significantly improved in both patient groups and so did subjective experience of pain. Satisfaction with current treatment also significantly increased during the study period. Frequency of side effects was low. In both GAD and MDD groups, two patients dropped out of the study due to adverse effects, leading to treatment termination in four cases (0.7%). Conclusions: This 8-week, multicenter, flexible-dosing, single-arm, open-label, observational real-life study in MDD and GAD patients switched to duloxetine after inadequate response or low tolerability to other ADs showed a significant positive effect on all outcome measures, including a significant decrease in illness severity as well as significant overall symptomatic improvement, with good tolerability.

[Professional identity of Hungarian psychiatrist. Experiences of a study]. / A magyar pszichiáter identitása. Egy tudományos felmérés tapasztalatai.

INTRODUCTION: A main determinant of professional identity is the integrity of the discipline. The complexity of psychiatry in biological, psychological and sociological aspects is a typical instance of the necessity for integration. AIM: Based on the bio-psycho-social dimensions and on their opinion about acceptance of psychiatry, we explored the professional identities of physicians working in Hungarian contemporary psychiatry. METHOD: Voluntary, anonymous responses were collected by using a 10-point evaluation scale on professional attitude, appreciation of psychiatry from lay society and other medical professions, and the importance of biology, psychology and sociology within psychiatry. RESULTS: The 228 respondents showed a highly significant effect of basic sciences: biology was the most relevant followed by psychology and sociology. Specialists in psychiatry (n = 171) showed a more marked preference for biology than the trainees, while specialists in psychotherapy (n = 74) considered the psychological component significantly more important than other respondents. The public acceptance of psychiatry was low as compared with other medical professions. CONCLUSIONS: The consistency between self-image and profession shows that the multidimensionality of psychiatry is not primarily an individual challenge. The impact on identity shows the key importance of education. Improving the prestige of psychiatry requires keeping our professional identity up-to-date, communicating with physicians with different preferences, and cooperating with other medical professions.

[The association between the serotonin receptor family and depression]. / A szerotonin receptorcsalád és a depresszió kapcsolata.

It is commonplace that depression is a heterogeneous mental disorder and this fact is the main driver of seek for aetiology and therapeutic opportunities. Selective serotonin reuptake inhibitors emerging in the 1980s are still among the most commonly prescribed medicines in the world. Due to their use, large groups of patients who previously remained untreated or treated at the cost of unwanted side effects of older antidepressants have chance to receive more optimal therapy. The background of the potential aetiology is multifaceted. However, we can point out that, according to the huge amount of data available, elements of the 5-HT system determine both directly and indirectly a number of emotional states, moods, stress responses, predispositions to affective diseases, and ultimately depression itself. In this article we review the role of relevant elements of the system and novelties in explanation of therapeutic mechanism.

Continuous maintenance antipsychotic treatment in schizophrenia.

During recent years concerns have been raised about the long-term cumulative and potentially negative impact of continuous maintenance antipsychotic treatment of schizophrenia on the human body, especially on the central nervous system. This paper aims at providing a summary of literature data on continuous maintenance treatment for practicing physicians. The results show that continuous maintenance antipsychotic treatment can significantly decrease the risk of relapses and improve the long-term outcome in schizophrenia. Regarding the long-term effects of antipsychotic treatment on the central nervous system, however, further research is needed to answer the question: are brain morphological and functional changes associated with the disease or the treatment or both? 'Based on the data available, low antipsychotic doses are effective and safe while high doses of antipsychotics should be avoided. This review concludes that the minimum effective doses of antipsychotics should be administered for continuous maintenance treatment.

Circadian clocks and tumor biology: what is to learn from human skin biopsies?

Some of the components of the circadian molecular clock have been shown to link directly to tumor suppression. Most studies on human tumorous biopsies with consistently down-regulated clock gene expression suggested a protective role for these genes against cancer formation. To highlight some limitations of this hypothesis we review these data in light of recent evidences from animal research, epidemiologic studies, and clinical data on skin tumors. We emphasize the role of circadian rhythmic orchestration in cellular metabolism with a potential in cancer development.

Altered expression patterns of clock gene mRNAs and clock proteins in human skin tumors.

The majority of our genes may be regulated in a daily rhythm, including the genes for cell cycle control. Epidemiological and genetic evidences suggest that disruption of circadian timing mechanisms makes our cells more vulnerable to cancer formation. The aim of this study was to investigate the relationship between expression patterns of circadian clock genes (period homolog (per)1, per2, clock, and cry1) and tumor development by analyzing human skin biopsies of malignant melanoma and nonmalignant naevus tumors. We found that mRNA levels and nuclear immunopositivity for the investigated clock genes were reduced by 30-60 % in both melanoma and in naevus biopsies if compared with adjacent nontumorous samples. The alterations in melanoma presented significant associations with clinicopathological characteristics (e.g., Breslow thickness). Contrary to previous reports, the moderate decrease of per1 expression seen in malignant tissues could not be linked to malignant transformation itself; rather, it reflects only the alterations in tissue composition. In turn, clock expression was upregulated in nontumorous cells of melanoma biopsies but not in melanoma cells or naevus cells. As this gene (clock) is closely related to cellular metabolism, our data suggest its role in the impaired regulation of metabolism in malignant tumors. Our results present the first clinical evidence for a possible link between circadian clock genes and human skin tumorigenesis.

Capsaicin-sensitive afferentation represents an indifferent defensive pathway from eradication in patients with H. pylori gastritis.

AIM: To study the role of capsaicin-sensitive afferent nerves in Helicobacter pylori (H. pylori) positive chronic gastritis before and after eradication. METHODS: Gastric biopsy samples were obtained from corpus and antrum mucosa of 20 healthy human subjects and 18 patients with H. pylori positive chronic gastritis (n = 18) before and after eradication. Traditional gastric mucosal histology (and Warthin-Starry silver impregnation) and special histochemical examinations were carried out. Immunohistochemistry for capsaicin receptor (TRVP1), calcitonin gene-related peptide (CGRP) and substance P (SP) were carried out by the labeled polymer immunohistological method (Lab Vision Co., USA) using polyclonal rabbit and rat monoclonal antibodies (Abcam Ltd., UK). RESULTS: Eradication treatment was successful in 16 patients (89%). Seven patients (7/18, 39%) remained with moderate complaints, meanwhile 11 patients (11/28, 61%) had no complaints. At histological evaluation, normal gastric mucosa was detected in 4 patients after eradication treatment (4/18, 22%), and moderate chronic gastritis could be seen in 14 (14/18, 78%) patients. Positive immuno-staining for capsaicin receptor was seen in 35% (7/20) of controls, 89% (16/18, P < 0.001) in patients before and 72% (13/18, P < 0.03) after eradication. CGRP was positive in 40% (8/20) of controls, and in 100% (18/18, P < 0.001) of patients before and in 100% (18/18, P < 0.001) after eradication. The immune-staining of gastric mucosa for substance-P was positive in 25% (5/20) of healthy controls, and in 5.5% (3/18, P > 0.05) of patients before and in 0% of patients (0/18, P > 0.05) after H. pylori eradication. CONCLUSION: Distibution of TRVP1 and CGRP is altered during the development of H. pylori positive chronic gastritis. The immune-staining for TRVP1, CGRP and SP rwemained unchanged before and after H. pylori eradication treatment. The capsaicin-sensitive afferentation is an independent from the eradication treatment. The 6 wk time period might not be enough time for the restituion of chronic H. pylori positive chronic gastritis. The H. pylori infection might not represent the main pathological factor in the development of chronic gastritis.

Comparative immunohistochemical study of tissue integration of macroporous and laminar surgical meshes.

Intraperitoneal surgical mesh implantation is required for laparoscopic ventral hernia repair. Composite meshes are well known in animal models and human practice. The aim of our study is to compare the biological behaviour of two different textured silicone-covered polypropylene meshes. Transmural abdominal wall defect was created in 40 rabbits and treated as follows: In 20 animals a polypropylene mesh with a laminar silicone covering (LSPP) and in the rest a macroporous textured mesh knitted of silicone-impregnated polypropylene filaments (MSPP) was applied. One and three weeks after implantation we evaluated the intraperitoneal adhesion formation of the mesh macroscopically, histologically and immunohistochemically to detect the reactive cells, especially inflammatory, endothelial and mesothelial cells, as well as their proliferative activity, and with Scanning Electron microscopy to visualize the surface of the meshes. The adhesion formation caused by the composites showed no statistical difference after one week although in the three weeks old samples the LSPP adhesion was significantly weaker than that of MSPP. As complications, serome formation in both groups, fistulas, abscesses, and sc. haematoma in the LSPP group were found. Only in MSPP containing tissues was the decrease of Ki-67 positive proliferating cells significant. A significant increase in VEGF expressing cells was observed only in MSPP containing three week old samples, suggesting better regulation of vascular growth in tissues surrounding the implants. In one week old specimens we observed an irregular proliferation of cytokeratin containing mesothelial cells in both group. The intraperitoneal surface of MSPP mesh was covered with neoperitoneum, while it was not regularly seen on LSPP mesh after three week.

[From the surgical field to the microscope. A new tool to identify the lymph node specimens in oncologic surgery]. / A mutotol a mikroszkópig. A rendszerezett nyirokcsomóminták azonosításának új eszköze a ráksebészetben.

Oncologic surgery and pTNM staging require systemic removal of the locoregional lymphnodes. While the optimal extent and therapeutical and/or prognostic value of the lymphadenectomy/sampling are debated organ by organ and (sub)speciality by (sub)speciality, relevance of the lymphnode sytem-tumor concept itself is beyond doubt. Loss of information and existence of traps on the "surgical field-microscope" pathway is an international phenomenon, calling for solution. An integrated sterile and disposable lymphnode tray system is presented here for applications in the different fields of cancer surgery of the upper GI tract, retroperitoneum (gynecology, urology) and ear-nose-throat surgery.

Two subgroups of schizophrenia identified by systematic cognitive neuropsychiatric mapping.

The description of the heterogeneous phenomenological, pathophysiological, and etiological nature of schizophrenia is under way; however, the relationships between heterogeneity levels are still unclear. We performed a robust cross-sectional study, including a systematic neuropsychological battery, assessment of clinical symptoms, neurological soft signs, morphogenetic anomalies and smell identification, and measurement of event-related potentials on 50 outpatients with schizophrenia in their compensated states. An explorative fuzzy cluster analysis revealed two subgroups in this sample that could be distinguished from each other on symptomatological, cognitive and neurological levels. The patterns of cognitive dysfunctions and neurological developmental anomalies equally indicate that there may be hemispherical differences between the patients belonging to the different clusters.

Effects of a hypnotically altered state of consciousness on intensification of semantic processing.

In a study of the linguistic processes involved in hypnosis, 22 volunteer medical students performed semantic and phonologic fluency tasks and then associative priming tests with 2 delay-lengths in waking alert and hypnotic conditions as well. The participants performed better during semantic than phonological fluency tests in alert and also in hypnotic states, and this difference was significantly greater in hypnosis. The increased semantic performance in hypnosis was accompanied by a decrease of the rule-offending errors. Significant semantic priming effects were detected in both states of consciousness in direct and indirect relations as well as in the automatic, intralexical level, and also when the extralexical control processes were activated. Overall, the results appear to show that the hypnotically altered state of consciousness produces significantly better performance in semantic information processing than can be elicited in alert waking conditions.

Abnormal neurological signs, visual contrast sensitivity, and the deficit syndrome of schizophrenia.

This study was designed to investigate the relationship between abnormal neurological signs, visual contrast sensitivity, and the deficit syndrome of schizophrenia. Visual contrast sensitivity for counterphase-modulated low spatial frequency gratings was measured in 32 non-deficit and 12 deficit schizophrenia patients and 20 healthy controls subjects. Abnormal neurological signs were evaluated with the Neurological Evaluation Scale (NES). Compared with the controls, patients with schizophrenia displayed impaired visual contrast sensitivity, which was associated with sensory integration deficits, as measured with the NES. The deficit syndrome was predicted by negative symptoms and sensory integration deficits. These results suggest that early-stage perceptual dysfunctions, which may reflect the abnormality of precortical magnocellular visual pathways, are related to a specific group of abnormal neurological signs.

Correlations between clinical symptoms, working memory functions and structural brain abnormalities in men with schizophrenia.

Thirteen male patients with schizophrenia and thirteen male normal control subjects were compared by magnetic resonance imaging (MRI) on volumes of the straight gyrus (SG), anterior cingulate gyrus, middle frontal gyrus, hippocampus, third ventricle, cavum septi pellucidi, total brain volume and intracranial volume. In addition, neuropsychological tasks were used to measure working memory and executive functions. Healthy volunteers and schizophrenic patients showed no significant differences in mean values for volumes of regions of interests. In the case of the SG, we found a significant difference in laterality: the tendency toward left dominance in healthy volunteers changed to significant right dominance in patients. The schizophrenic patients showed lower performance in working memory tasks, and strongly significant group differences were observed in measures of neurological signs assessed by the Neurological Evaluation Scale (NES). Negative symptoms correlated with the level of spatial working memory and executive functions. Negative symptoms also correlated with the volume of the right hippocampus, while the rate of anhedonia negatively correlated with the relative volume of the left SG.

Participation of vanilloid/capsaicin receptors, calcitonin-gene-related peptide and substance P in gastric protection of omeprazole and omeprazole-like compounds.

The effects of omeprazole and different omeprazole-like compounds, associated with anti-ischaemic, antioxidant and poly(adenosine-diphosphate-ribose) polymerase (PARP) inhibitory properties, on the gastric acid secretion (4 h pylorus-ligated) and indomethacin-induced gastric mucosal damage connected with the specific immunohistochemical distribution of TRPV1, CRGP and SP during the effects of these compounds, were studied. The observations were carried out in CFY-strain rats (180-210 g), according to the standard methods and the above-mentioned parameters were studied in these experimental circumstances without and with application of different compounds. We found that: (1) all of the compounds dose-dependently inhibited the gastric acid secretion and mucosal damage; (2) the expression of TRPV1 receptor, CGRP and SP decreased significantly in both pylorus-ligated and indomethacin-treated animals and (3) the expression of TRPV1 and CGRP was reduced. Meanwhile, no change was obtained in SP expression during the gastric mucosal protection produced by omeprazole and omeprazole-like compounds. The conclusions were that (1) a functional overlap exists between the capsaicin-sensitive afferent and efferent vagal nerve during omeprazole effects; (2) chemical modification of omeprazole molecule offers a new pathway to obtain a new drug for the introduction in the clinical practice.

Immunohistochemical distribution of vanilloid receptor, calcitonin-gene related peptide and substance P in gastrointestinal mucosa of patients with different gastrointestinal disorders.

The immunohistochemical distribution of capsaicin/vanilloid (transient receptor potential vanilloid 1, TRPV1) receptors and neuropeptides (CGRP, SP) was studied in the gastrointestinal mucosal biopsies of patients with gastritis, erosions, ulcers, polyps, adenocarcinoma, chronic inflammatory bowel diseases, polyps without and with hyperplasia, dysplasia and adenocarcinoma in colon. The studies were carried out in 127 patients and 30 people with only functional dyspepsia (without any histological alteration). The results were: (1) the positivity of TRPV1 receptor and CGRP was detected, and weak participation of SP was detected in patients with different gastric diseases; (2) the presence of TRPV1, CGRP and SP could be detected in chronic inflammation of bowel disease; (3) SP could not detected in patients with colon polyps, dysplasia and adenocarcinoma; (4) the presence of TRPV1 and CGRP was proved in colon dysplasia and adenocarcinoma. We conclude that (1) the immunohistochemical distribution of TRPV1, CGRP and SP differs in gastrointestinal diseases of the upper and lower tract, and (2) the participation of TRPV1, CGRP and SP differs significantly in these different gastrointestinal diseases.
