RESUMO

BACKGROUND: Based on promising effects seen in a pilot study evaluating a generic mindfulness-based program for migraine, we developed a migraine-specific adaptation of the Mindfulness-Based Cognitive Therapy (MBCT) program. The aim of this study was to evaluate this program for feasibility and effectiveness in a randomized controlled trial. METHOD: Fifty-four patients suffering from migraine were randomly allocated to either waitlist or the adapted MBCT. Outcomes were migraine-related parameters as well as variables of psychological functioning and coping. Assessment took place at baseline and post-intervention, for the intervention group also at follow-up (7 months). The effects of the intervention were analyzed by the use of ANCOVAs and linear mixed models. RESULTS: With respect to migraine parameters we did not find a significant group difference in the primary outcome (headache-related impairment), but the intervention resulted in a significant reduction of headache frequency (p = .04). In the analysis of secondary outcomes, MBCT showed superiority in four out of eight psychological parameters (perceived stress, anxiety, rumination, catastrophizing) with small to medium effect sizes. The intervention proved to be feasible and participants reported high degrees of contentment and achievement of personal goals. CONCLUSIONS: The migraine-specific MBCT program did not result in improvements with regard to headache-related impairment but showed a reduction in headache frequency as well as improved psychological functioning in secondary outcomes. TRIAL REGISTRATION: This trial was registered in the German Trial Registry "Deutsches Register Klinischer Studien" (ID: DRKS00007477), which is a WHO-listed primary trial register.

RESUMO

Patient history taking and semiology provide seminal clues to the diagnosis of dissociative seizures. Openness and alertness of the treating physician are essential. Video-electroencephalogram(EEG)-based analyses of the events are crucial to establish the correct diagnosis, particularly in complex cases. The patient-doctor relationship is of particular importance in order to successfully motivate the patient for psychotherapeutic treatment. Coexisting psychiatric morbidity as well as other functional somatic symptoms must be actively explored. Current changes in the established diagnostic manuals, including ICD-11, reflect the ongoing vivid interest and controversial discussions in the field of dissociative disorders.

RESUMO

OBJECTIVES: This study aimed to examine the association of adipocyte fatty acid-binding protein (FABP4) levels with left ventricular diastolic dysfunction (LVDD) in obese subjects with varying degrees of the metabolic syndrome (MetS). METHODS: Fifty morbidly obese subjects with LVDD were selected at random and matched by age (±5 years) and sex with 50 morbidly obese with normal left ventricular (LV) function. In addition, 24 healthy lean subjects were included as controls. RESULTS: Median FABP4 levels (interquartile range) in obese subjects with LVDD were significantly higher (42 ng ml(-1) (32-53)) than in obese with normal LV function (24 ng ml(-1) (36-43), P=0.036), and in normal weight controls (13 ng ml(-1) (10-20), P<0.0001). Increasing FABP4 tertiles were significantly associated with parameters of LVDD, the number of LVDD components, physical performance and epicardial fat thickness. In multivariate regression analysis adjusting for age, sex and adiposity, FABP4 levels remained significantly associated with parameters of diastolic function. The association of FABP4 levels with LVDD was mainly observed in subjects with metabolic complications, but not in metabolically healthy obese. CONCLUSIONS: FABP4 levels are significantly associated with LVDD in obese subjects, when the MetS is present. Thus, FABP4 may be a link between obesity and cardiometabolic disorders.

RESUMO

This report describes the objectives, design, and methods of the Munich Diagnostic and Predictor Study of Dizziness, a prospective study investigating diagnostic subgroups, correlates, and predictors of dizziness that is not sufficiently explained medically but clearly related to a psychiatric disorder. All patients presenting at the Integrated Centre for Research and Treatment of Vertigo, Balance and Ocular Motor Disorders at the University Hospital Großhadern in Munich, Germany, are investigated during their first-time visit. The study consists of a baseline and two follow-up assessment points at 6 and 12 months. At the baseline assessment point, all participants complete self-rated questionnaires concerning dizziness, depression, anxiety, dissociative and traumatic experiences, somatization, body sensations and perception, cognitions, attachment, personality, quality of life and experiences with the health care system. Additionally, a structured clinical interview is conducted to assess mental disorders. Then, the neurologists complete questionnaires regarding the subjective doctor-patient relationship and to document the somatic diagnoses and results. The follow-up measurements consist of self-rated questionnaires. This study aims to improve the diagnosis and treatment of patients who suffer from dizziness related to a psychiatric disorder and who are often severely impaired in their working and daily lives.

RESUMO

BACKGROUND: Multisomatoform disorder is characterised by severe and disabling bodily symptoms, and pain is one of the most common and impairing of these. Furthermore, these bodily symptoms cannot be explained by an underlying organic disorder. Patients with multisomatoform disorder are commonly found at all levels of healthcare and are typically difficult to treat for physicians as well as for mental health specialists. AIMS: To test whether brief psychodynamic interpersonal therapy (PIT) effectively improves the physical quality of life in patients who have had multisomatoform disorder for at least 2 years. METHOD: We recruited 211 patients (from six German academic outpatient centres) who met the criteria for multisomatoform disorder for a randomised, controlled, 12-week, parallelgroup trial from 1 July 2006 to 1 January 2009 (International Standard Randomised Controlled Trial Number ISRCTN23215121). We randomly assigned the patients to receive either 12 weekly sessions of PIT (n = 107) or three sessions of enhanced medical care (EMC, n = 104). The physical component summary of the Short Form Health Survey (SF-36) was the pre-specified primary outcome at a 9-month follow-up. RESULTS: Psychodynamic interpersonal therapy improved patients' physical quality of life at follow-up better than EMC (mean improvement in SF-36 score: PIT 5.3, EMC 2.2), with a small to medium between-group effect size (d = 0.42, 95% CI 0.15-0.69, P = 0.001). We also observed a significant improvement in somatisation but not in depression, health anxiety or healthcare utilisation. CONCLUSIONS: This trial documents the long-term efficacy of brief PIT for improving the physical quality of life in patients with multiple, difficult-to-treat, medically unexplained symptoms.

RESUMO

Illness behaviour involves cultural, situational and personal predispositions. World Wide Web search statistics provided by internet applications like Google Insights for Search have the potential to facilitate our research on the distribution of mental disorders, our understanding of both sociocultural imprintings and trends in psychophenomenology and could make a remarkable contribution to medical research and public health.

RESUMO

BACKGROUND: About 30-50% of complex dizziness disorders are organically not sufficiently explained or related to a psychiatric disorder. Of patients with such dizziness disorders, 80% are severely impaired by dizziness in their daily and working lives; nevertheless, they are often not diagnosed or treated adequately. OBJECTIVES: This review aims to give a systematic overview of psychotherapeutic approaches and their efficacy regarding the treatment of dizziness that is medically not sufficiently explained or related to a psychiatric disorder. METHODS: A systematic literature search was conducted in Medline, PSYNDEX and PsycINFO. Included in this systematic review were (randomised) controlled trials ((R)CTs) concerning psychotherapy in patients with dizziness, medically not sufficiently explained or associated with a psychiatric disorder. If possible, Hedges' g was used to express the effect sizes (ES) of the treatment. Heterogeneity was assessed using the Q statistic. In addition, the quality of the studies was rated. RESULTS: Three (R)CTs were included. All studies used cognitive-behavioural treatment methods in combination with relaxation techniques or vestibular rehabilitation. All studies suggested that psychotherapy may provide improvement. The mean ES in the treatment groups was 0.46 (95% CI 0.05 to 0.88) for dizziness related outcome, 0.10 (-0.44 to 0.64) for anxiety and 0.17 (-0.24 to 0.58) for depression whereas in the control groups the mean dizziness related ES was -0.04 (-0.44 to 0.37), anxiety related ES was -0.03 (-0.43 to 0.38) and depression related ES was -0.02 (-0.42 to 0.38). The quality of the studies was average. Sample sizes were small, however, and there was a lack of long term studies. CONCLUSION: This systematic review provides some preliminary evidence that psychotherapy may be effective in patients with dizziness that is medically not sufficiently explained or due to a psychiatric disorder. The results should be replicated in larger samples and follow-up RCTs.

RESUMO

Somatoform symptoms occur in the absence of clear organic pathology. Typically, such symptoms are long-lasting and disabling. Somatoform symptoms and disorders are highly prevalent in primary care. The course of somatoform disorders is mostly chronic, and remission rates are low. Multiple factors influence the development and perpetuation of somatoform disorders. Currently, there is strong debate about the classification of somatoform disorders, and it is very likely that there will be significant changes in the classification of somatoform disorders in the upcoming DSM-V. With regard to the psychotherapeutic treatment of somatoform disorders, there is empirical evidence for the efficacy of cognitive-behavioral as well as psychodynamic-interpersonal strategies. Pharmacotherapy plays a minor role, but it can be useful mainly in cases of comorbid depression or anxiety.

RESUMO

BACKGROUND: Asthma is a frequently disabling and almost invariably distressing disease that has a high overall prevalence. Although relaxation techniques and hypnotherapeutic interventions have proven their effectiveness in numerous trials, relaxation therapies are still not recommended in treatment guidelines due to a lack of methodological quality in many of the trials. Therefore, this study aims to investigate the efficacy of the brief relaxation technique of functional relaxation (FR) and guided imagery (GI) in adult asthmatics in a randomized controlled trial. METHODS: 64 patients with extrinsic bronchial asthma were treated over a 4-week period and assessed at baseline, after treatment and after 4 months, for follow-up. 16 patients completed FR, 14 GI, 15 both FR and GI (FR/GI) and 13 received a placebo relaxation technique as the control intervention (CI). The forced expiratory volume in the first second (FEV(1)) as well as the specific airway resistance (sR(aw)) were employed as primary outcome measures. RESULTS: Participation in FR, GI and FR/GI led to increases in FEV(1) (% predicted) of 7.6 +/- 13.2, 3.3 +/- 9.8, and 8.3 +/- 21.0, respectively, as compared to -1.8 +/- 11.1 in the CI group at the end of the therapy. After follow-up, the increases in FEV(1) were 6.9 +/- 10.3 in the FR group, 4.4 +/- 7.3 in the GI and 4.5 +/- 8.1 in the FR/GI, compared to -2.8 +/- 9.2 in the CI. Improvements in sR(aw) (% predicted) were in keeping with the changes in FEV(1) in all groups. CONCLUSIONS: Our study confirms a positive effect of FR on respiratory parameters and suggests a clinically relevant long-term benefit from FR as a nonpharmacological and complementary therapy treatment option.

RESUMO

Psychosomatic rehabilitation and the concluding social-medical assessment constitute a particular challenge. The aim of this study was to examine whether inpatient psychosomatic rehabilitation in the context of an integrated treatment concept, conducted in Turkish and German, is effective in the rehabilitation of Turkish migrant laborers, and what concluding socio-medical assessment results from this treatment. 195 Turkish patients--44 male and 151 female--received inpatient psychosomatic treatment for approximately 40 days. Sociodemographic, psychiatric and social-medical data were recorded, as well as Symptom Checklist (SCL-90-R) testing upon admission and discharge. A predominant number of patients were laborers, with a low level of primary education, who were afflicted with psychosocial problems and dissatisfaction with their workplace and who first came into psychosomatic treatment many years following the onset of their illness. Many of them had a clearly defined desire to retire. At the end of their admission, a significant improvement in almost all the scales of the SCL-R-90 was ascertained on the one hand, but on the other, adequate socio-medical results were hardly observed. The symptoms' improvement would confirm that the combination of service offerings in Turkish and German proved themselves. A portion of the patients (approx. 40 %) were classified subsequent to treatment as capable of working for 6 hours or more. Nevertheless, approximately approx. 75 % still sought to retire. Timely psychosomatic treatment could counteract chronification of the illness and the establishment of a steadfast desire to enter retirement, and consequently represent an improvement in the prognosis. Likewise, consistent psychosomatic training of physicians, as well as systematic prophylactic measures with the migrant laborers, should be considered.

RESUMO

Whether the treatment results in inpatient psychotherapy are significantly influenced by the patient's motivation is a subject of discussion. The goal of this study was to assess whether the primary motivation for therapy in depressive women influences the results of psychotherapeutic treatment. In a prospective study, the monitored results from 64 female inpatients (32 who were highly motivated to enter therapy, and 32 who were minimally motivated) were compared to each other. The period of observation was six weeks. As instruments of assessment, the Fragebogen zur Therapiemotivation (FMP) (Questonnaire on Motivation for Entering Therapy) and the Beck Depression Inventory (BDI) were aministered upon admission; after the fourth and sixth weeks of therapy, the Veränderungsfragebogen des Erlebens und Verhaltens (VEV) (Questionnaire of Changes in Experience and Behavior) was administered as well. All patients who had applied for a pension were found in the group of less motivated patients and consolidated into a subgroup. The analysis was carried out according to the intent-to-treat principle. The variance analysis for the repeat measurements showed significant differences on all the FMP scales and on the BDI (all P< 0.001). The measurements with VEV likewise resulted in a significant difference (P< 0.01). The subgroup of "pension patients" showed significantly less change in all three of the above measurements. Patients with depressive symptomology who essentially are relatively highly motivated for therapy could profit significantly more from inpatient psychosomatic treatment than those who are less motivated. Establishing and developing motivation prior to inpatient hospitalization could possibly contribute to more efficient and cost-effective clinical treatment. Where legal proceedings pertaining to a pension are pending, relatively less motivated patients fare significantly worse not only in their motivational development for therapy, but also in their final treatment results. It should be noted, however, that the relatively small random sample, the restricted blinding, which was only partially possible, could have led to possible distortions.

RESUMO

OBJECTIVE: Extreme obesity causes grave psychosocial and psychopathological problems in addition to somatic morbidity. One possible treatment is gastric banding, a surgical reduction of stomach volume. The aim of this study was to investigate whether gastric banding leads to lasting change in: 1) the Body Mass Index (BMI); 2) social factors such as work and partnerships, eating behavior, anxiety and depression symptoms; and 3) health related quality of life. METHOD: We surveyed a sample of 50 adipose women (BMI > 40 kg/m2). Primary outcome measures were self-reported changes on the scales of the Three-Factor Eating Questionnaire (TFEQ), the Hospital Anxiety and Depression Scale (HADS-D), and the Health Survey (SF-36). RESULTS: In comparison with the control group, we observed significant changes in BMI (p < 0.01) and the existence of a partnership (p < 0.01), on all three scales of the TFEQ (p < 0.01), on both scales of the HADS-D (anxiety: p < 0.05; depression:p < 0.01), and on all scales of the SF-36 Health Survey (p between < 0.05 and < 0.01 in every case). The most marked changes in all the qualities investigated occurred within the first 12 months of surgery. CONCLUSIONS: Three years after gastric banding, positive changes in BMI reduction, partnership, eating behavior, anxiety, depressive symptomatology, and health related quality of life could be observed. There was also a significant correlation between BMI reduction and reduction firstly on the depression scale (HADS-D) and secondly on the SF-36 scales for physical functioning (PHFU), role physical (ROPH), mental health (PSYC), and vitality (VITA).

RESUMO

Repeated exposure to solar ultraviolet radiation results in premature skin aging due, in part, to the degradation of dermal collagen by fibroblast collagenase (matrix metalloproteinase 1 [MMP-1]). We have established TaqMan reverse transcription (RT) polymerase chain reaction (PCR) systems to quantify the messenger RNA (mRNA) expression of MMP-1 and its specific inhibitor TIMP-1 in human buttock skin exposed in vivo to solar simulated radiation (SSR). A time-course study (n = 6) with two minimal erythema doses (MED) of SSR showed maximal induction of MMP-1 and TIMP-1 at 24 h. A dose-response study (n = 6) sampled at 24 h revealed that doses of about 1 MED were necessary to induce expression of MMP-1 mRNA, and our data suggest that the response is saturated at about 2 MED. We also investigated SSR-induced gene expression in the dermis and epidermis separately (n = 5). MMP-1 was present in both tissues, but TIMP-1 was only detected in the dermis. In general, we could only measure MMP-1 mRNA in the nonirradiated control skin of volunteers who were smokers. We hypothesize very large interpersonal variation with MMP-1 induction compared with TIMP-1 which was detected in all the control sites. This suggests a lack of relationship between MMP-1 and TIMP-1 mRNA expression. The large donor variability for MMP-1 in all the studies demonstrates that it is important to analyze gene expression individually.

RESUMO

Smokers look older than non-smokers of the same age. We have compared the concentrations of mRNA for matrix metalloproteinase 1 (MMP-1) in the buttock skin of smokers and non-smokers with quantitative real-time polymerase chain reactions. MMP-1 degrades collagen, which accounts for at least 70% of the dry weight of dermis. We report significantly more MMP-1 mRNA in the skin of smokers than non-smokers whereas no difference was seen for the tissue inhibitor of metalloproteinases 1 (TIMP-1) or the housekeeping gene GAPDH (glyceraldehyde-3-phosphate dehydrogenase). We suggest that smoking-induced MMP-1 might be important in the skin-ageing effects of tobacco smoking.

RESUMO

The results of 119 radioimmunoscintigraphies (RIS) in 113 patients with the 99mTc-labeled monoclonal anti-CEA-antibody BW 431/26 (Behring) have been analysed. The aim of our study was the estimation of the method's sensitivity and specificity under different aspects to find out for which indications and questions the 99mTc-RIS is useful. Colorectal primary tumours in 19 patients were scintigraphically detected with a sensitivity of 83% and a specificity of 100%; 3 out of 7 other tumour sites were localised correctly. 55 patients were examined during the follow-up of colorectal cancer. There were 17 out of 22 true positive findings of local recurrences (sensitivity 77%, specificity 88%). Liver metastases were imaged as hot lesions with only 41% sensitivity and 86% specificity. The detection of extrahepatic tumour sites is difficult because of the persistently high blood-pool activity of the monoclonal antibody and, in the pelvic area, the unspecific bowel activity. Skeletal metastases were recognised in 7 out of 9 cases. In 14 patients with other non-colorectal carcinomas, RIS was successful in single cases. It is not helpful, however, when searching for tumours of unknown origin or for the screening of patients with elevated CEA levels without tumour history. The high technical, methodological and time effort required by RIS is justified in the follow-up of cancer patients when conventional diagnostic procedures are inconclusive or the status of morphological findings remains unclear. The use of RIS as an unspecific screening tool in tumour diagnosis must be rejected because of the not completely explored risks of the examination. Repeated applications of monoclonal antibodies require controls of the patients' HAMA titers before performing RIS.
