Congenital esophageal stenosis presenting as noncardiac,esophageal chest pain

Summary A case of a 31-year-old female with congenital esophageal stenosis presenting with symptoms of chest pain caused by esophageal dysmotility is described. The involved segment in congenital esophageal stenosis has a characteristic thickening of the muscularis propria layer, as seen by EUS examination. In these patients, symptoms of dysphagia can be managed with esophageal dilation and noncardiac esophageal chest pain responds to pharmacotherapy with diltiazem.The opinions and assertions contained herein are the private ones of the authors and are not to be construed as official policy or reflecting the views of the Army or the Department of Defense.

Relationship of "bleeding on probing" and "gingival index bleeding" as clinical parameters of gingival inflammation

Abstract Bleeding on probing (BOP) and the gingival index have been used to clinically characterize the degree of gingival inflammation. It is, however, unclear to what extent these parameters correlate to each other and to probing pocket depth (PD). The purpose of this clinical study was to evaluate the association between BOP and GI bleeding (scores of 2 and 3), as well as the relationship of these variables to PD, in a group of patients presenting with naturally-occurring gingivitis. Based on screening examinations of 125 subjects with at least 20 teeth, no more than 4 sites with PD over 6 mm, a BOP frequency of 30% or greater, and no systemic condition that would influence the inflammatory response, were selected. 2 weeks after screening they were examined at 6 sites per tooth for plaque index, GI, PD and BOP. A standardized pressure sensitive probe (Florida Probe) with 20 g probing force was used for BOP and PD measurements. In this population, means of 40.9% (S.E.= 1.36) BOP sites and 35.3% (S.E, = 1.81) GI bleeding sites per patient were found. A total of 20,008 sites ranging in PD up to 5.9 mm were evaluated; however, the majority of sites (19,723, 98.6%) presented with <4 mm PD. When sites were evaluated, BOP demonstrated a positive correlation with PD, whereas GI bleeding correlated with PH. For sites characterized by the absence of BOP as well as the absence of GI bleeding (scores 0 and 1), the highest % of agreement between the 2 indices (77.7%) was found in shallow sites (0.1–2 mm). In contrast, when sites presenting with both BOP and GI bleeding were analyzed, the highest % of agreement (85,4%) was found for sites with PD >4.0 mm. In this gingivitis population group, it appears that BOP and GI bleeding evaluate distinct inflammatory1 conditions of the gingival tissues, and the relationship between the 2 clinical parameters may vary according to PD at the individual site examined.     

丙氧氨酚与酮咯酸治疗癌痛的比较

晚期肿瘤疼痛病人３１例（男性１７例，女性１４例，年龄５０±５１４ａ），用丙氧氨酚２片，ｐｏ，ｔｉｄ，共７ｄ。相似病人３０例（男性１６例，女性１４例，年龄５１±１３ａ），用酮咯酸１０ｍｇ，ｐｏ，ｑｉｄ，共７ｄ。结果：疼痛强度（标尺法）２组均有降低；显效时间前组（丙氧氨酚）快于后组（酮咯酸）；药效维持时间后组长于前组；不良反应前组嗜睡多于后组，而胃肠道不适少于后组。     

5-羟色胺对大鼠脊髓P物质痛觉调制的影响(英文)

比较SP,5-HT与For诱发的脊髓内c-fos表达的异同,以及它们之间的相互关系,从而进一步了解SP在脊髓痛觉调制中的主要作用.方法:用免疫组织化学法和痛阈测定法.结果:发现大鼠it P物质(sP)10μg和sc5％甲醛(For)150μL诱发的脊髓c-fos表达主要在背角Ⅰ,Ⅱ,Ⅴ及Ⅵ层,同时SP使痛阈降低,For使痛级均数(PIR)升高.5-HT it 20μg引起的c-fos表达较多地分布于背角Ⅲ—Ⅳ层,并可使痛阈升高.5-HT和Fen可分别减弱和增加SP及For诱发的脊髓c-fos表达及痛反应.结论:SP在脊髓内可能主要起致痛作用,5-HT可抑制SP引起的脊髓c-fos表达,从而参与SP的痛觉调制作用.

A daily process design study of attentional pain control strategies in the self-management of cancer pain.

This study investigated the use of attentional control strategies in the self-management of pain using daily process design methodology. Twenty six cancer patients with pain completed diaries 3 times daily for 10 days. Diaries incorporated measures of pain intensity, affect, coping, coping efficacy, and the novelty and predictability of pain, and participants completed a cross-sectional measure of catastrophizing. At the across-person level, focusing on pain was associated with increased negative affect, and the use of pain focusing strategies was positively correlated with experiencing pain that was novel in its location or quality. Distractions that were interesting, important and pleasant were positively correlated with positive affect, perceptions of control over pain and ability to decrease pain. Over-prediction of pain was positively correlated with catastrophizing, and negatively correlated with perceptions of control over and ability to decrease pain. The within-person analysis (ARIMA modelling) showed that catastrophizing moderated the effects of pain focusing strategies, novel pain and over-predictions of pain. Meta-analysis of the ARIMA models revealed that the within-person effects of using attentional strategies did not generalize across the sample. These findings indicated that the effects of distraction strategies are influenced by their motivational-affective significance rather than the frequency with which they are used, and provided further evidence that the threat value of pain influences the way in which people cope with their pain. Theoretical and clinical implications are discussed.     

Do ethnicity and gender have an impact on pain thresholds in minor dermatologic procedures?

Background and Objectives: The perception of pain is a personal experience influenced by many factors, including genetic, ethnic and cultural issues. Understanding these perceptions is especially important in dermatologic patients undergoing minor surgical operations and who often differ in their pain response to surgical treatments. Little is known about how these differences affect the perception of experimental pain. The purpose of this study was to determine experimental pain perception differences in three distinct East Asian ethnic populations.
Methods: Pain thresholds were examined with a psychophysical computerized quantitative thermal sensory testing device (TSA 2001) in healthy volunteers recruited from three different Asian ethnic groups. Using the methods of limits, experimental pain perception threshold was measured on the forehead and volar aspect of the forearm in 49 healthy subjects. The measurements were then repeated after skin barrier perturbation with adhesive tape stripping of the stratum corneum. All three ethnic groups were analyzed separately with respect to age, gender educational level and skin type.
Results: A total of 20 Chinese, 14 Malay and 15 Indian subjects completed the study. Thermal pain thresholds were similar in all three ethnic groups before and after tape strippings. No significant differences were noted between genders.
Conclusions: Using quantitative sensory thermal testing, we demonstrated that no significant differences in pain occur between different races and genders.
