Skin test results and self-reported symptom severity in allergic rhinitis: the role of psychological factors

BACKGROUND: In allergic conditions, the degree of skin test reactivity does not always correlate with the severity of clinical symptoms. Additional factors may contribute to the reported symptom severity. OBJECTIVES: To investigate the association between the magnitude of the skin prick test (SPT) response and the reported symptom severity in patients with allergic rhinitis and the possible modifying role of psychological factors. METHODS: One hundred four patients with allergic rhinitis and 23 with non-allergic rhinitis, classified according to their SPT response to 19 aeroallergens, were asked to rate the severity of five symptoms and to indicate whether their symptoms intensified on exposure to five common aeroallergens. They also completed a psychological questionnaire. Results Reported symptom severity of allergic rhinitis did not correlate with weal size for any of the aeroallergens tested or with the number of positive responses on SPT. It was not related to patient age, sex, or education. The reported symptoms severity correlated positively (0.29, P < 0.01) with reported symptom intensification on exposure to allergens. Moreover, both outcomes were positively associated with the psychological factors of hypochondriasis (0.20, P < 0.05 and 0.18, P < 0.05, respectively), and somatic awareness (0.24, P < 0.05 and 0.33, P < 0.01, respectively), but not with neuroticism. CONCLUSIONS: The severity of symptoms experienced by patients with allergic rhinitis is apparently not related to the magnitude of SPT response, but rather to psychological factors of hypochondriasis and somatic awareness. Physicians should be aware of the contribution of psychological factors to patient perceptions of the intensity of symptoms and of the intensification of symptoms on their exposure to allergens.     

社会能力评定量表的编制及信效度检验

目的：编制社会能力评定量表并检测其信度和效度。方法：在全国五大行政区用社会能力评定量表评估1605例正常人(男性814名，女性791名)，分析量表的信效度。结果：全量表的Cronbach's α系数为0．88-0．92，三个分量表的d系数为0．81～0．88；量表的分半信度为0．76～0．87，量表的重测信度为0．67～0．86，量表评分者信度为0．91～0．97，表明量表具有较好的内部一致性和稳定性；各条目与总分的相关系数0．49-0．80，分量表与总分的相关系数为0．76～0.89，通过因子分析，证实了量表的结构效度；全量表总分和职业能力得分与被试单位提供的实际社会能力评分呈高度相关，与韦氏智商呈中低度相关。结论：量表编制符合心理测量学要求，具有良好的信度和效度。     

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.     

Discrimination of idiopathic pain syndromes from neurogenic pain syndromes and healthy volunteers by means of clinical rating,personality traits,monoamine metabolites in CSF,serum cortisol,platelet MAO and urinary melatonin

Summary The aim of the present study was to investigate the discriminative power of a series of variables (including determination of depressive symptomatology by means of a visual analogue scale, determination of personality traits by means of the Karolinska Scales of Personality, determination of monoamine metabolites in CSF, platelet MAO activities, serum cortisol before and after dexamethasone suppression and urinary melatonin) in differentiating (a) chronic pain patients from healthy subjects, and (b) patients with idiopathic pain syndromes from patients with neurogenic pain syndromes. Separately each of the measures gave a significant but often low contribution to the discrimination, while a combination of several measures gave a complete discrimination both between healthy subjects and patients with chronic pain syndromes and between patients with idiopathic and neurogenic pain syndromes, respectively.Supported in part by grants from the Swedish Medical Research Council (grants no. 3371, 4145 and 5740) and by a grant from Stiftelsen Söderström-Königska Sjukhemmet     

持续正压通气辅助治疗高血压并发睡眠呼吸暂停综合征的临床研究

目的探讨持续正压通气辅助治疗高血压并发睡眠呼吸暂停综合征（SAS）对血压的影响。方法41例高血压并发睡眠呼吸暂停综合征病人,随机分为常规组（21例）和持续正压通气治疗组（20例）均给予常规降压药物治疗4周,治疗在常规治疗基础上加用气道持续正压通气治疗,观察两组治疗前后24 h血压变化。结果治疗组治疗后24 h平均收缩压、舒张压进一步降低,夜间收缩压及舒张压则显著降低（P〈0.01）。结论高血压并发睡眠呼吸暂停综合征病人,在常规应用降压药物同时应用持续正压通气辅助治疗血压下降更理想。
