Validating the eating disorder inventory (EDI‐2) in two danish samples: A comparison between female eating disorder patients and females from the general population

The Eating Disorder Inventory, Version 2 (EDI‐2) is a questionnaire used clinically and in research all over the world. EDI‐2 is cross‐culturally valid, yet normative values may depend on culture. Norms and reliability of the Danish version have to date been lacking, and will be presented in this article, comparing patients (N = 575) and controls (N = 881). Also, internal reliability of scales is tested for both groups. Differences between norms of the Danish and the North American version of EDI were small but significant for all scales except asceticism (eating disorder patients) and ineffectiveness, interpersonal distrust and maturity fears (normal controls). For both groups the internal consistency was >0.70 for all subscales except asceticism. Although differences across the eating disorder diagnostic groups were dubious, the EDI‐2 is useful to screen for eating problems in the general population as well as to rate progress and outcome among eating disorder patients.

Reduced serotonin-1A receptor binding in social anxiety disorder.

BACKGROUND: Results from studies in serotonin-1A (5-HT1A) knockout mice and previous positron emission tomography (PET) studies in humans imply a role for 5-HT1A receptors in normal state anxiety as well as in certain anxiety disorders. The objective of this study was to investigate 5-HT1A receptor binding potential (BP) in social anxiety disorder (SAD). METHODS: Using PET and [carbonyl-11C]WAY-100635, we compared a homogeneous group of 12 unmedicated, male SAD patients with 18 healthy control subjects (HC). A multivariate ANOVA with all regional BP values as dependent variables, age and four radiochemical variables as covariates was performed. RESULTS: We found a significantly lower 5-HT1A BP in several limbic and paralimbic areas but not in the hippocampus (p = .234) of SAD patients. The difference in 5-HT1A binding was most significant in the amygdala (-21.4%; p = .003). There was also a more than 20% lower 5-HT(1A) BP of SAD patients in the anterior cingulate cortex (p = .004), insula (p = .003), and dorsal raphe nuclei (p = .030). CONCLUSIONS: The lower 5-HT1A binding in the amygdala and mesiofrontal areas of SAD patients is consistent with 1) preclinical findings of elevated anxiety in 5-HT1A knockout mice, 2) a previous PET study in healthy volunteers showing an inverse correlation between 5-HT1A BP and state anxiety, and 3) another human PET study in patients with panic disorder showing reduced 5-HT1A binding, thus corroborating the potential validity of 5-HT1A receptors as targets in the treatment of human anxiety disorders.     

心血管疾病并发焦虑抑郁症状2050例心理干预治疗分析

目的:了解心血管疾病并发焦虑抑郁症状的情况并探讨心理干预等对焦虑抑郁症状的影响。方法:对住院的2050例心血管疾病并发焦虑抑郁症状的患者进行回顾性分析。结果:心血管疾病患者中并发有焦虑抑郁症状者占56%;其常表现为类似心绞痛、左心衰竭症状,可并发有心律失常;高血压病并发有焦虑抑郁患者对血压升高的耐受性差,动态血压检查以非勺型改变者居多;单纯使用心血管药物治疗效果欠佳,心理干预,焦虑抑郁症状严重者结合抗焦虑抑郁药物疗效显著。结论:心血管疾病患者常并发焦虑抑郁症状,心理干预治疗等可有效改善患者的症状。     

On the physical properties of red cell ghost membranes in the affective disorders and psychoses A fluorescence polarization study

Membrane order was measured in the erythrocyte ghost membranes of DSM-III schizophreniform disorder (SF), DSM-III schizophrenic (SCZ) and DSM-III manic (bipolar) (M) patients and a group of age- and sex-matched controls. Fluorescence polarization with the probe 1,6-diphenyl1-1,3,5-hexatriene was used to determine the steady-state fluorescence anisotropy (r_s). The SF group showed a significant increase in r_s (Δr_s = 0.037) from the control group. Although the means were not significantly different, 3 of 8 Ms and 5 of 8 SCZs also had r_s values > the highest control value. Thermotropic behavior of the membranes was evaluated over the range of 40 to 20°C. No difference among groups in membrane enthalpy was detected. Thus, the differences in r_s appear to be associated with differences in entropy. Phosphatidylcholine (PC) levels, which were known to be abnormal in these patients, were compared with the r_s values. A significant (P < 0.001, R= -0.63) linear correlation between r_s and membrane PC levels was observed. Overall these data further support the view that unusual membrane biophysical factors may occur with high frequency in the psychoses and affective disorders.     

The pattern evoked response in disorders of the optic nerve

The pattern evoked electroretinogram (PERG) was investigated in 11 patients with unilateral optic nerve disease and in a series of age-matched controls. The visually evoked potential (VEP) was also measured. The PERG showed a similar reduction to the VEP in optic nerve disease. Serial studies indicate that the PERG may not be affected immediately in some instances but may show a gradual decline over several months.     

精神病住院病例45年抽样分析

目的　对 4 5年来本院住院精神病病例的病种、分型、治疗措施和疗效等作一简要的回顾总结。方法　将自 195 4年 5月到 1999年 9月入院的病人 ,按首次入院日期每隔五年连续抽取 10 0份病例 ,扼要摘录有关内容进行登记、统计、分析。结果　男女病例数大致相仿。平均年龄 (31 9± 12 1)岁 ,平均住院日期 (6 2 1± 36 3)月 ,遗传史阳性率占 2 3 4 % ,精神分裂症占 5 4 % ,心境障碍占 13% ,癔症占 12 5 % ,电休克应用例数自 195 4年的 4 1 5 %降到 1999年的 2 % ,胰岛素治疗自 195 4年的 4 8%逐渐降低到 1989年 4 % ,1999年后为零。药物治疗西药自 5 7年的一种 (氯丙嗪 )增加到 1999年的 2 0余种。中药治疗经过 195 9年和 1970年的两个高潮 ,新针治疗自 196 9年至 1989年亦告结束。两者均无明显疗效。精神分裂症和心境障碍的显效率平均为 70 6 %和 90 8%。但均有评价过高之嫌。结论　根据我院的实践 ,传统的中药方剂、单味草药和“新针”治疗对主要精神病无明显疗效 ,195 9年后住院病人的疗效有明显的提高 ,愈来愈多的抗精神病药和取代了原有的胰岛素休克和电休克治疗。
