While systemic autoimmune diseases are the main possibilities in the differential diagnosis of scleritis, other less common etiologies such as infections must also be considered. The authors report four cases of infectious scleritis to review predisposing factors, clinical characteristics, methods of diagnostic approach, and response to therapy. Two patients had primary scleritis and two patients had secondary scleritis following extension of primary corneal infection (corneoscleritis). Diagnoses included three local infections (one each withStaphylococcus. Acanthamoeba, and herpes simplex) and one systemic infection (Lyme disease). Stains, cultures, or immunologic studies from scleral, conjunctival, and/or corneal tissues, and serologic tests were used to make the diagnosis. Medical therapy, including antimicrobial agents, was instituted in all patients, and surgical procedures were additionally required in two patients (scleral grafting in one and two penetrating keratoplasties in another); the patient who required two penetrating keratoplasties had corneoscleritis and underwent eventual enucleation. Infectious agents should be considered in the differential diagnosis of scleritis. 相似文献

The author describes his surgical approach to the problems of the aging upper arm and elbow region. Surgery at an appropriate age can prevent the progressive wrinkling of the elbow which is further aggravated by aging of the upper arm. The author's operation is aimed at correcting both portions of the arm anatomy at the same time. 相似文献

几丁糖预防术后腹腔粘连的实验研究 总被引:1,自引:1,他引:0
目的探讨几丁糖对术后腹腔粘连的预防作用.方法将45只大鼠随机分为A、B、C 3组,于腹腔内浆膜损伤部位分别注入1%乳酸液、32%右旋糖酐-70液和2%几丁糖乳酸液各2 ml,术后14 d处死动物,观察各组腹腔粘连状况.结果 3组粘连分级比较有显著性差异(P<0.01),C组粘连发生率与另2组有显著差异(P<0.05).光镜下C组炎症反应轻微,纤维增生不明显;电镜下C组纤维细胞分泌胶原能力弱,间皮细胞增生活跃.结论几丁糖可有效降低大鼠术后腹腔粘连的发生和粘连程度,其作用优于右旋糖酐-70,且不影响切口的愈合. 相似文献

Bacterial components regulate the expression of Toll-like receptor 4 on human mast cells 总被引:3,自引:0,他引:3
Y. Kubo N. Fukuishi M. Yoshioka Y. Kawasoe S. Iriguchi N. Imajo Y. Yasui N. Matsui M. Akagi 《Inflammation research》2007,56(2):70-75
Objectives and design: The aim of this study was to investigate whether the exposure of mast cells (MCs) to bacterial components affects the expression
of Toll-like receptor (TLR) 4, and to elucidate the behavior of MCs during the early response to infection.
Materials: Two human MC lines, HMC-1 and LAD2, were employed. Messenger RNA expression was observed by RT and real-time PCR. TLR4 expression
was determined by Western blotting. TNF-α secretion was analyzed with ELISA. The degranulation ratio was measured with betahexosaminidase
assay.
Results: Although bacterial components increased TLR4 mRNA, only lipopolysaccharide (LPS) augmented the TLR4 protein expression. LAD2
pre-treated with LPS for 8 h resulted in 2-fold increased TNF-α secretion on LPS restimulation.
Conclusion: These results suggest that the exposure of MCs to LPS may reinforce the innate immune system due to up-regulation of MC TLR4,
followed by increased TNF-α release.

OBJECTIVE: To explore pregnancy outcome in HIV-1-positive and HIV-negative women, and mother-to-child transmission (MTCT) according to mode of delivery under effective highly active antiretroviral therapy (HAART). DESIGN: Cohort of 143 pregnant HIV-1-infected women including a matched case-control study in a 2:1 ratio of controls to cases (n=98). SETTING: Academic Medical Center in Amsterdam and Erasmus Medical Center in Rotterdam, the Netherlands. POPULATION: Consecutive referred HIV-1 infected pregnant women treated with HAART and matched control not infected pregnant women. MAIN OUTCOME MEASURES: MTCT, preterm delivery, low birthweight, pre-eclampsia. RESULTS: MTCT was 0% (95% CI 0-2.1%). Seventy-eight percent of HIV-1-infected women commenced and 62% completed vaginal delivery. The calculated number of caesarean sections needed to prevent a single MTCT was 131 or more. Preterm delivery rates were 18% (95% CI 11-27) in women infected with HIV-1 and 9% (95% CI 5-13) in controls (P=0.03). HAART used at <13 weeks of gestation was associated with a 44% preterm delivery rate compared with 21% when HAART was started at or after 13 weeks and 14% in controls. (Very) low birthweight and incidence of pre-eclampsia were not different between HIV-1 and controls. CONCLUSIONS: We have not demonstrated any MTCT after vaginal delivery in women effectively treated by HAART. The HAART-associated increase in preterm delivery rate is mainly seen after first trimester HAART use. 相似文献

胃幽门弯曲菌感染对胃癌发生影响的探讨 总被引:1,自引:1,他引:0
应用Warthin-starry镀银技术检查胃幽门弯曲菌,对中国胃癌高发区及美国胃癌高发区新奥尔良检查了300例具有胃症状的胃粘膜标本。结果发现幽门弯曲菌阳性率为60~62%,并且看到这种细菌的感染与慢性胃炎病变的程度有明显的关系。本文探讨了幽门弯曲菌的感染与胃癌癌前病变的关系。 相似文献
