In a study of bowel parasites in 128 Australian homosexual men attending a sexually transmitted diseases (STD) clinic, Entamoeba histolytica was detected in 37%, Giardia intestinalis in 3% and at least one protozoan in 81% of the group. There was no evidence of pathogenicity of E. histolytica, nor was there any association between the detection of E. histolytica and sexual practices, gastrointestinal symptoms, proctitis, human immunodeficiency virus antibody result or T-cell subset values. However it was noted that those subjects with an elevated IgM greater than 4 g/l were more likely to harbour E. histolytica trophozoites than those with a level below 4 g/l (OR 6.54, 95% CI 1.3-32.8). Travel to South-East Asia, India, China, Africa, South America or the Pacific islands in the previous 3 years emerged also as an independent factor (OR 2.70, 95% CI 1.12-6.53) associated with detection of E. histolytica. 相似文献

We report a case of appendicial paraganglioma in a 40 year old female who presented with acute appendicitis and underwent laparoscopic appendectomy. To the best of our knowledge this is the first reported case of appendicial gangliocytic paraganglioma with features suggestive of malignancy in the modern literature. Van Eeden S. et al. reported the first case of appendicial paraganglioma in a 47 year old man who also presented with acute appendicitis. The appendectomy specimen showed a distended appendix with thickened wall, and a 1.3 cm mucosal based yellow lesion. Microscopically this lesion was centered in the submucosa and consisted of three different cell types: (a) epithelioid cells with pale eosinophilic finely granular cytoplasm containing bland oval nucleus with stippled chromatin, that form solid nests lying in a trabecular pattern and in formations reminiscent of ‘Zellballen’ as seen in paragangliomas (b) second type cells have large vesicular nuclei with prominent nucleoli and abundant cytoplasm that are scattered singly, (c) third type cells with bland elongated nuclei form broad fascicle and envelop the epithelioid and ganglion cells. Immunohistochemical analysis showed the epithelioid cell nests immunoreactive for synaptophysin and the ganglion-like cells and spindle Schwann cells to be immunoreactive for S100 protein, whereas all three cells populations were negative for CAM5.2 and Pancytokeratin. We do believe that an accurate diagnosis of Gangliocytic paraganglioma (GP) of the appendix was rendered, detailed microscopic examination of doubled hematoxylin and eosinophil stained sections as well as the immunohistochemical phenotype of the three components have been undertaken to confirm the diagnosis of GP. 相似文献

In a cross-sectional study of 140 homosexual men attending a sexually transmissible diseases clinic, the association between the presence of antibody to the human immunodeficiency virus (HIV) and the presence of proctitis, as determined by histologic examination, as well as part or present exposure to other pathogens and details of sexual practices was analyzed. Significant associations with HIV seropositivity were found with the number of lifetime partners, positive treponemal serology, and evidence of previous infection with herpes simplex virus. However the major and unique finding was the strong and independent association between proctitis diagnosed by histologic criteria and seropositivity for HIV. Whether this is cause or effect awaits further elucidation. 相似文献

The role of antibiotic and probiotic therapies in current and future management of inflammatory Bowel disease 总被引:2,自引:0,他引:2
Abundant evidence indicates that the intestinal microflora have a role in the pathogenesis of inflammatory bowel disease (IBD).
The composition of the gut microflora is altered in IBD patients with increased "pathogenic" bacteria and decreased bifidobacteria
and lactobacilli. In light of this dysbiosis, various methods have been examined to alter the composition of the intestinal
microflora, including the administration of antibiotics and introduction of probiotic species. This article summarizes studies
evaluating the efficacy of antibiotics and probiotics in the induction and maintenance of remission of ulcerative colitis,
Crohn’s disease, and pouchitis. 相似文献

Anterior cruciate ligament (ACL) rupture is a common sporting injury, often managed surgically with patella-tendon or hamstrings-gracilis autograft. Some people who sustain the injury, request information about their prognosis if they choose to forgo surgery and opt for conservative management. Numerous studies provide data on the prognosis of conservatively managed ACL injuries. These studies have not been systematically reviewed. Thus, the aims of this systematic review are to describe the natural history and clinical course of function and proprioception in the conservatively managed ACL-deficient knee, and to identify prognostic factors. We searched MEDLINE, CINAHL, EMBASE, SportDiscus, PEDro and the Cochrane Central Register of Clinical Trials without language restrictions from the earliest record available up to July 2006. We also searched the Science Citation Index, and iteratively searched bibliographies for prospective studies of outcomes (>6 months follow-up) of conservatively managed complete ACL tears. Six criteria were used to assess the methodological quality of included studies. The main outcome measures were self-reported measures of knee function, activity level, performance in functional tasks and knee proprioception. Fifteen studies of variable methodological quality were included in the review. On average, patients with mixed or isolated ACL-deficient knees reported good knee function (87/100 Lysholm knee scale) at follow-up duration of 12-66 months. On average, functional performance assessed with the hop-for-distance test, was in the normal range. From pre-injury to follow-up there was a reduction in Tegner activity level of 21.3%. According to the methods used in the assessed studies, conservatively managed ACL-deficient knees have a good short- to mid-term prognosis in terms of self-reported knee function and functional performance. However, subjects reduced their activity levels on average by 21% following injury. 相似文献

OBJECTIVES--(I) to determine the relative sensitivities of clinical examination, cytology and HPV DNA hybridisation for the detection of anal human papillomavirus infection; and (ii) to examine various factors which may influence presentation of anal human papillomavirus infection in homosexual men. METHODS AND RESULTS--112 unselected homosexual men attending a Sydney STD clinic for routine screening underwent a complete anogenital and physical examination, during which blood samples (for haematological, serological and immunological investigations), rectal swabs (for culture of anal pathogens) and anal scrapes of the dentate line (for cytology and HPV DNA hybridisation) were collected. Papanicolaou-stained anal smears were examined for cytological abnormalities, including those indicative of HPV infection or anal intraepithelial neoplasia (AIN). HPV DNA was detected by high stringency dot hybridisations using radiolabelled HPV 6, 11, 16 and 18 DNA probes. Visible anal condylomata, situated either externally or in the anal canal, were present in 26% of these men; 46% had cytological evidence of HPV infection, and 19% of the smears showed evidence of mild to moderate dysplastic changes (AIN I-II). Detectable HPV DNA was present in 40% of the anal scrapes. By combining these results, a total of 73 men (65%) were found to have at least one of the indicators of HPV infection. These data, together with that relating to HIV antibody, immune status and past or present infection with other STDs, was correlated with information obtained from a questionnaire administered to the patients at the time of their clinical examination. CONCLUSIONS--In this study cytology was found to be slightly more sensitive than HPV DNA dot hybridisation for the detection of HPV infection in the anal canal, providing the full range of HPV-associated cytological changes were accepted as a basis for diagnosis. Clinical anal lesions were more likely to be detected in young men, men who had symptomatic HIV infection and those with a history of past anal wart infection. The latter group also had a higher incidence of cytologically apparent HPV infection in their anal smears. There was a significant association between the detection of HPV 16/18 and the presence of anal dysplasia, but there were no significant correlations between HPV infection or anal dysplasia and HIV antibody, immune function status, sexual practices or history of other STDs. 相似文献
