Urine samples from 402 victims of ski accidents were analyzed for the presence of benzodiazepines (BZD) and alcohol. Eighty-one (20%) samples were positive for alcohol; BZD were detected in 34 (8.5%) cases. Ten of the samples (2.5%) were found to be positive for both alcohol and BZD. Subjects who were positive for either alcohol or BZD or both were older than the other persons examined. The prevalence of alcohol was significantly higher among male accident victims. BZD intake could be demonstrated to have a significant influence on the severity of injuries. Besides an increased awareness of the need for skier education regarding drug use, heightened attention of medical caregivers is warranted to inform their patients about potential accident hazards in sport activities when BZD are prescribed. 相似文献

Background: Fructose malabsorption is characterized by the inability to absorb fructose efficiently. As a consequence fructose reaches the colon where it is broken down by bacteria to short fatty acids, CO2, H2, CH4 and lactic acid. Bloating, cramps, osmotic diarrhea and other symptoms of irritable bowel syndrome are the consequence and can be seen in about 50% of fructose malabsorbers. Recently it was found that fructose malabsorption was associated with early signs of depressive disorders. Therefore, it was investigated whether fructose malabsorption is associated with abnormal tryptophan metabolism. Methods: Fifty adults (16 men, 34 women) with gastrointestinal discomfort were analyzed by measuring breath hydrogen concentrations after an oral dose of 50 g fructose after an overnight fast. They were classified as normals or fructose malabsorbers according to their breath H2 concentrations. All patients filled out a Beck depression inventory questionnaire. Blood samples were taken for plasma tryptophan and kynurenine measurements. Results: 相似文献

A great number of studies show biological alterations in patients with schizophrenia, but many of these data are conflicting. Schizophrenia is a vastly heterogeneous disorder, most likely not caused by one etiological factor, but rather due to a complex network of different, interacting pathogenic influences. Variable clinical pictures may reflect different etiological factors. In a comprehensive theory of the origin of schizophrenic disorders, genetic and environmental influences cause changes in neuronal development which result in functional alterations of different neurotransmitter systems. Immunological research in schizophrenia was initially based on the "infection hypothesis" which was triggered by observing schizophrenia-like psychoses after influenza pandemic. Numerous immunological studies focusing on antibodies against specific viruses, unspecific antibodies and different other immune-phenomena were carried out in schizophrenia patients. Although the variability of the results from these studies is strikingly high, subgroups of patients with schizophrenia show an activated inflammatory response system with increased levels of proinflammatory cytokines and acute phase proteins. Furthermore, some investigations find changing activities in the T-cell system with a shift of TH-1 to an increased TH-2 activity. Endocrinological factors which may play a relevant role in the etiopathogenesis of schizophrenia include sex hormones and all changes caused by stress or other influences which are directly related to the HPA-axis. Alterations of the immune and the endocrinological systems might be caused by environmental factors like infections or exogenous stress. Due to the intensive interaction between the central nervous system, the immune system and different hormones the "development of a pathology" like schizophrenia can be seen in an integrative but multifactorial fashion. The clinical manifestation, the severity and the course of the disease might then be modulated by genetic vulnerability, the time of the "primary insult" -- which could be an infection, or psychological stress -- and its neuronal localisation and intensity. Different compensatory and decompensatory mechanisms in later life very likely play a crucial role for the further course of the disorder. 相似文献

OBJECTIVE: To assess normalization in the lives of liver transplant patients and the impact of preoperative expectations on postoperative quality of life (QOL). DESIGN: A semistructured interview, 2 QOL questionnaires, and chart reviews of medical histories. SETTING: Internal medicine department at Innsbruck university hospital, Austria. PARTICIPANTS: Fifty-five patients (32 men, 23 women) with liver transplants. INTERVENTIONS: The Sickness Impact Profile (SIP) and Functional Assessment of Cancer Therapy-General. RESULTS: Patients' preoperative expectations of a normal life style posttransplantation were predominantly optimistic (60%), but postoperatively only 40% thought that their expectations had been realized. The patients' SIP values showed significant impairments in nearly every area of life when compared with the values of a healthy control group. Only "complications during the hospitalized phase" had a statistically significant impact among the sociodemographic and clinical parameters on postoperative QOL. The lowest QOL scores were found among patients whose expectations of a return to normal life style had not been realized. CONCLUSION: Unmet life-style expectations after liver transplantation may lead to increased stress, which affects QOL long term. This finding is of clinical relevance; therapeutic measures, particularly professional pretransplant counseling, are indicated. 相似文献

To reinvestigate the viral hypothesis of schizophrenia as well as possible immunological dysfunction, neopterin, which is an indicator of the activity in the cellular immune system, was determined in acute and chronic schizophrenics. Both diagnostic groups showed neopterin levels within the normal range. Patients with chronic schizophrenia of the residual type presented a significant dependency between neopterin concentrations and Brief Psychiatric Rating Scale (BPRS) total scores. In a long-term observation of 14 acute schizophrenic (paranoid type) inpatients, neopterin levels were found to be lowest at day 0. During the first week of treatment neopterin concentrations increased significantly whereas a concomitant decrease of the psychopathological symptoms could be observed. In comparison to healthy controls patients showed significantly lower neopterin levels at baseline. These findings will be discussed referring to the viral hypothesis of schizophrenia as well as to possible immunological alterations caused by stress or by changes in neurotransmitter synthesis. 相似文献

Zotepine in the treatment of schizophrenic patients with prevailingly negative symptoms. A double-blind trial vs. haloperidol. 总被引:1,自引:0,他引:1

Zotepine, a neuroleptic agent with additional 5-HT2 blocking properties, was compared with haloperidol in the treatment of schizophrenic patients with predominantly negative symptoms using a double-blind design. During the investigation period zotepine treated patients showed significant improvements in all rating instruments whereas haloperidol treated patients did not. Patients in the zotepine group developed fewer clinical side effects. The results of the presented study confirm the positive impressions gained in earlier open trials with zotepine. 相似文献

BACKGROUND: Activation of the tryptophan-degrading enzyme indoleamine (2,3)-dioxygenase was demonstrated to be critically involved in tolerance induction to prevent fetal rejection. Our study was designed to examine alterations of tryptophan and its catabolic product kynurenine in the postpartum period and to compare them to neopterin as an immunological marker. METHODS: 95 healthy women delivering without complications provided blood during labour, and 2 and 4 days after birth. The blood samples were analysed for concentrations of tryptophan, kynurenine and neopterin. Women were asked to perform the Edinburgh Postnatal Depression Scale (EPDS) on days 2 and 4. RESULTS: In women without blues symptoms (n=86) tryptophan concentrations increased within 2 days after birth, whereas they did not change in women with postpartum blues (n=9; 9.5%). The group difference reached statistical significance (p<0.05). The change of the kynurenine to tryptophan ratio (kyn/trp), which estimates the degree of tryptophan degradation, was also different between the two groups at days 0 and 2 (p<0.05). Neopterin concentrations decreased between days 2 and 4 (p<0.05), but there were no differences between the two groups. LIMITATIONS: Our study population had a low prevalence of postpartum blues symptoms. CONCLUSION: Low postpartal mood is associated with continuously low serum tryptophan after delivery due to an increased degradation to kynurenine, but is independent of the postpartal course of neopterin. 相似文献

Psycho-oncology is defined by psychosocial aspects of prevention, etiology, diagnostics, treatment, and rehabilitation of cancer. It is characterized by interdisciplinary medicine, as well as cooperation between medical and nonmedical professionals. Psychosocial distress and/or psychiatric disorders are manifested in 30-60% of cancer patients. The primary target of psycho-oncological management is to retain and ideally optimize the subjective quality of life of cancer patients. It is important to understand that psycho-oncological care is part of an integrative oncological patient management. Basic psycho-oncological management is usually provided by the primary oncologist, whereas more specific psycho-oncological measures call for specially trained psychiatric/psychotherapeutic staff. Psycho-oncological interventions include psychological/psychotherapeutic, as well as psychopharmacologic interventions. 相似文献

Alzheimer's disease (AD) is the most prevalent type of dementia. Despite considerable advances in diagnostic accuracy, diagnostic procedures that are easily accessible are still sorely needed. Blood biomarkers are therefore in the focus of research. Platelets contain a high concentration of the amyloid precursor protein (APP), which has been mentioned as a potentially useful diagnostic marker. The aim of the present study was to analyze various cell adhesion molecules (CAMs), cytokines, growth factors, and matrix metalloproteinases (MMPs) in platelets of AD and mild cognitively impaired (MCI) patients as compared to healthy controls. Our data show a significant decrease in the levels of epidermal growth factor (EGF) and of MMP-2 in platelets of AD patients and decreased levels of MMP-2 in MCI. The APP ratio was slightly but not significantly decreased in AD patients, whereas CD40L and serotonin were unchanged. Our findings demonstrate specific changes in AD platelets. Whether these biomarkers can be established as potential early diagnostic biomarkers for AD remains to be established in longitudinal studies. 相似文献
