Mirizzi综合征的影像学诊断

目的:探讨Mirizzi综合征的发病机理、临床表现、影像学诊断及术前诊断的重要价值.方法:查阅了大量的相关资料文献,进行对比、分析、总结归纳.结果:Mirizzi综合征是胆道系统感染的一种特殊类型,临床少见,极易造成漏诊和误诊,在术中造成不必要的胆道损伤和胆总管探查,影像学检查在诊断此综合征方面有较多的独特优势.结论:Mirizzi综合征术前可以通过影像学检查尤其是超声检查明确诊断.

目的 评价Manning标准诊断肠易激综合征(IBS)的真实性。方法 采用自行设计的调查表对499例对象进行调查。结果 1．随着Manning标准中结合指标数的增多，IBS组与非溃疡性消化不良及溃疡性结肠炎组鉴别的灵敏度及其95％CI明显下降，特异度及其95％CI明显上升，同时阳性预测值、阳性似然比及阴性似然比也明显上升。2．符合Manning标准中二项以上结合指标，IBS组就具有较好与健康对照组鉴别的灵敏度及其95％CI、特异度及其95％CI。结论 Manning标准中需要3项以上结合指标可较好地使IBS与非溃疡性消化不良或溃疡性结肠炎鉴别；2项以上结合指标可较好地使IBS与健康人鉴别。     

Cutaneous manifestations in the cardiofaciocutaneous syndrome, a variant of the classical Noonan syndrome. Report of a case and review of the literature

We report one patient with cardiofaciocutaneous (CFC) syndrome. He presented with clinical findings characteristic of this condition such as: cutaneous abnormalities, including ichthyosis, widespread keratosis pilaris, a peculiar craniofacial appearance with sparse, curly hair and low-set posteriorly rotated ears; congenital heart defects; and mild mental and motor retardation. We submit a comprehensive review of previously published articles regarding the dermatological findings in CFC syndrome (recently shown to be a variant of Noonan syndrome) emphasizing diagnostic criteria and its differentiation from the Costello syndrome.     

Acute pustulosis of the legs in diverticulitis with sigmoid stenosis: an overlap between bowel-associated dermatosis–arthritis syndrome and pustular pyoderma gangrenosum

BACKGROUND: Bowel-associated dermatosis-arthritis syndrome denotes the occurrence of diarrhoea with arthritis and skin lesions related to bowel disease with or without bowel bypass. In this condition, the histological finding of cutaneous aseptic neutrophilic cell infiltrate is non-specific and common to a wide spectrum of neutrophilic dermatoses, including pyoderma gangrenosum. OBSERVATION: We describe a 78-year-old woman with fever, abdominal discomfort and arthralgias, who developed grouped pustular lesions on her shins with histologically spongiform pustule formation. Aetiological assessment disclosed diverticular disease with sigmoid stenosis. CONCLUSION: Although clinical and histological features in our case fit the diagnosis of bowel-associated dermatosis-arthritis syndrome, they may also correspond to a pustular variant of pyoderma gangrenosum. Our observation raises the question of the nosological classification of bowel-associated dermatosis-arthritis syndrome within the spectrum of neutrophilic diseases.     

左双腔支气管导管管端位置与吸气峰压变化的关系

目的 观测无隆突钩双腔支气管导管(DLT)管端位置与吸气峰压(Ppeak)以及肺顺应性环形状改变的关系，探讨用Ppeak和顺应性环的变化评估DLT管端位置的可行性。方法 拟行右侧剖胸手术的成年患者32例，静脉诱导后插入左Mallinckrodt DLT，吸入氧化亚氮和地氟醚维持麻醉。按纤维支气管镜(FOB)确认DLT管端位置和通气方式将观测过程分为四个阶段：第一阶段(S1)，管端位置正确的双肺通气；第二阶段(S2)，管端位置正确的左侧单肺通气；第三阶段(S3)，管端插入左下支气管(置管过深)的左侧单肺通气；第四阶段(S。)，管端处在左支气管开口(置管偏浅)的左侧单肺通气。每阶段均机械通气15min。结果 回归方程预计插管深度与FOB检查符合者占71．9％。S2时Ppeak值比S1时增加50．8％，肺顺应性(Cdyn)值减少36．2％；S3时Ppeak值比S1时增加87．4％，Cdyn值减少56．8％。PV环曲线斜率向右明显移位，环体显著延长。结论 用无隆突钩DLT行肺隔离，在无FOB定位的条件时，联合应用听诊法、回归方程预计插管深度、动态监测气道峰压和P-V环的变化综合评估，可提高DLT管端的正确到位率。单肺通气的气道峰压超过双肺通气时的1．65倍，且气道峰压超过25cm H2O．应高度怀疑DLT管端发生过深移位。

Inhaled allergen-driven CD1c up-regulation and enhanced antigen uptake by activated human respiratory-tract dendritic cells in atopic asthma

Background Dendritic cells (DC) mediate inflammation in rodent models of allergic airway disease, but the role played by human respiratory‐tract DC (hRTDC) in atopic asthma remains poorly defined. Recent data suggest that CD1 antigen presentation by hRTDC may contribute to asthma pathogenesis. Objective To investigate the influence of hRTDC on the balance between atopy and allergic asthma in human subjects and to determine whether CD1 expression by hRTDC is modulated during asthmatic inflammation. Methods Sputum cells were induced from steroid‐naïve, allergen‐challenged and allergen‐naïve subjects (atopic asthmatics, atopic non‐asthmatics and non‐atopic controls). hRTDC were identified using monoclonal antibody labelling and analysis by flow cytometry. Results hRTDC stained HLA‐DR⁺ (negative for markers of other cell lineages) were predominantly myeloid and comprised ∼0.5% of viable sputum cells. Sputum cells were potent stimulators of allogeneic CD4⁺ naïve T cells and enrichment/depletion experiments correlated stimulatory potency with DC numbers. Sputum contained cells that exhibited typical dendritic morphology when analysed by electron microscopy. Myeloid hRTDC were endocytically active, but uptake of FITC‐dextran was enhanced in cells from asthmatics (P<0.001). Despite their increased endocytic capacity, asthmatic myeloid hRTDC appeared mature and expressed increased levels of maturation markers (P<0.05–P<0.001), CD1c, CD1d and langerin (P<0.05). CD1c expression by asthmatic myeloid hRTDC was enhanced upon in vivo allergen challenge (three to ninefold within 24 h; P<0.05). CD11c⁻CD123^high hRTDC were only detected in asthmatic sputum and were increased in number following allergen challenge. Conclusion Despite limited cell numbers, it proved possible to analyse human RTDC in induced sputum, providing evidence that increased antigen uptake and enhanced CD1 presentation by activated hRTDC may contribute to allergic airway disease. CD1 presentation by hRTDC in atopic asthma may therefore constitute a novel target for future intervention strategies.
