Evaluation of Eye Movement Desensitization and Reprocessing in the management of tinnitus. An observational study

ObjectivesTinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus.Materials and methodsThis was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score > 17, causing psychological distress motivating active treatment after ineffective “classic” treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy.ResultsThirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P < 0.0001; 64.8 ± 20.8 before versus 31.8 ± 24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P < 0.0001; 7.24 ± 2.12 before versus 3.58 ± 2.03 after treatment). The treatment acceptability was 86.8%.ConclusionEMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of “classic” first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.     

神经症患者主客观生活事件的影响因素

目的研究应对方式、社会支持和压力反应等与应激有关因素对神经症患者主观、客观生活事件的影响。方法应用自编生活事件量表、压力反应问卷、特质应对问卷、领悟社会支持量表及一般情况调查表对88例神经症患者和88名健康对照进行调查和分析。结果神经症组主观事件得分[(13.295±11.845)分]高于健康组[(7.261±10.873)分](P<0.01),而神经症组客观事件得分[(10.239±9.105)分]与健康组得分[(8.376±11.213)分]差异无显著性(P>0.05)。神经症组主观事件与压力反应正相关,与家庭内支持和年龄负相关(P<0.01),客观生活事件与应激其他因素均无关;健康对照组主观事件与压力反应正相关,客观生活事件与压力反应和消极应对正相关(P<0.01)。多元逐步回归分析提示,影响神经症组主观事件的因素依次有客观事件、年龄、压力反应和家庭内支持,预测力为47.7%;但影响神经症组客观事件、健康组主观事件和客观事件的仅有相对应的主观或客观事件。结论神经症患者主观事件报告明显多于健康人群,且神经症患者主观事件受其他压力有关因素的影响较大。     

研究生主观幸福感与人格特征相关研究

目的探讨研究生的主观幸福感与人格的关系。方法采用艾森克人格问卷量表与总体主观幸福感量表（GWB）对200名研究生进行测验。结果（1）在专业、性别、年级、年龄、婚姻状况上及来源上，研究生的主观幸福感不存在显著差异。（2）相关分析表明外向性人格纬度与总体幸福感存在显著的正相关，神经质与总体幸福感存在显著的负相关。稳定外向型和稳定内向型人格的总体幸福感水平最高，其次是不稳定外向型人格，总体幸福感水平最低的是不稳定内向型人格。结论外向性与神经质等人格特征是影响研究生幸福感的重要因素。     

Ill-health as a household norm: Evidence from other people's health problems

This paper proposes that an individual's self-assessed health (SAH) does not only suffer from systematic reporting bias and adaptation bias but is also biased owing to confounding health norm effects. Using 13 waves of the British Household Panel Survey covering the period 1991–2005, I show that, while there is a negative and statistically significant correlation between SAH and individuals' own health problem index, this negative effect reduces with the average number of health problems per (other) family member. The relative health bias is small, however, which implies that measures of SAH may not suffer seriously from systematic health norm bias. This is an important finding for researchers working with SAH data as it indicates that we do not have to worry too much about controlling for confounding influences from the health of other household members when estimating SAH regression equations.

The discriminative stimulus and subjective effects of d-amphetamine,phenmetrazine and fenfluramine in humans

The discriminative stimulus (DS) and subjective effects of d-amphetamine (AMP), phenmetrazine (PMT) and fenfluramine (FFL) were studied in a group of normal healthy adults. Subjects (N=27) were trained to discriminate between placebo and 10 mg AMP (PO). Fourteen of the subjects (discriminators) reliably learned the discrimination, whereas the other 13 did not. Nearly all discriminators labelled AMP as a stimulant, and AMP, relative to placebo, increased ratings of drug liking and general activity level, and produced typical stimulant-like subjective effects, as measured by the Profile of Mood States, the Addiction Research Center Inventory, and a series of visual analog scales. The discrimination accuracy of discriminators increased as a function of hour after drug ingestion, as did analog ratings of how certain subjects were that their discrimination responses were correct. Discriminators were tested with doses of PMT (25 and 50 mg) and FFL (20 and 40 mg) to determine whether the DS properties of these drugs would substitute for those of AMP. Both doses of PMT consistently substituted for AMP, and PMT produced subjective effects very similar to those of AMP. Conversely, neither dose of FFL consistently substituted for AMP, and FFL produced essentially no subjective effects. These findings are consistent with results from discrimination studies with other species, and provide further evidence of the validity of this procedure for studying the DS properties of drugs in humans.

Nicotine discrimination and self-administration in humans as a function of smoking status

Nicotine’s discriminative stimulus effects may be critical to understanding reinforcement of tobacco smoking. It is not known whether regular nicotine exposure produces tolerance or sensitivity to these effects. In this study, male and female smokers (n = 11) and never-smokers (n = 10) were trained to discriminate 20 μg/kg nicotine by nasal spray from placebo (0) on day 1. On day 2, both groups were tested on generalization of this discrimination across intermittent presentations of 0, 3, 6, 12, and 20 μg/kg nicotine in random order. Quantitative and quantal behavioral discrimination tasks, used in previous research, were employed. On day 3, subjects were instructed to self-administer sprays from the 20 μg/kg nicotine versus 0 bottles in a concurrent-choice procedure. All but one subject (female smoker) learned reliably to discriminate 20 μg/kg nicotine from placebo (≥ 80% correct) on day 1. Nicotine-appropriate responding on day 2 was attenuated in smokers versus never-smokers at 20 μg/kg on the quantitative task and at 12 μg/kg on the quantal task, suggesting tolerance. There was no difference in responding at other doses. Smokers also showed attenuated responses on the subjective measure of “head rush”, which was associated with discrimination responding in both groups. Nicotine self-administration was significantly greater in smokers versus never-smokers, who self-administered nicotine below chance levels, and was inversely related to discrimination behavior in never-smokers but unrelated in smokers. Women smokers showed less change in nicotine-appropriate responding across generalization doses, reported less confidence in discriminating training doses during acquisition on day 1, and tended to self-administer less nicotine on day 3. These results indicate that smokers may become tolerant to the discriminative stimulus effects of nicotine, perhaps promoting increased use.

Sex differences in plasma cocaine levels and subjective effects after acute cocaine administration in human volunteers

Gender differences after acute cocaine administration have received little attention in spite of the fact that males and females respond differently to many drugs. Seven male and seven female occasional cocaine users received both an intranasal dose of cocaine hydrochloride (0.9 mg/kg) and placebo powder in a randomized order and reported subjective effects via an instrumental joystick device and various questionnaires. Blood samples were withdrawn at 5-min intervals to assess pharmacokinetic differences. Male subjects achieved the highest peak plasma cocaine levels (144.4 ± 17.5 ng/ml), detected cocaine effects significantly faster than females and also experienced a greater number of episodes of intense good and bad effects. Women studied during the follicular phase of their menstrual cycle had peak plasma cocaine levels of 73.2 ± 9.9 ng/ml, which was significantly higher than when they were studied during their luteal phase (54.7 ± 8.7 ng/ml), but there were no differences in their subjective reports of cocaine effects. In spite of the different cocaine blood levels and subjective effects, peak heart rate increases did not differ between males and females suggesting that women may be more sensitive than males to the cardiovascular effects of cocaine. These data suggest that there are significant gender and menstrual cycle differences in the response to acute intranasal cocaine administration and these differences may have implications for the differential abuse of this drug.This paper is dedicated to Xavier Lamas, MD, PhD, who lost his life while ascending Mt.
