目的探讨微创玻璃体切除术后引起早期高眼压的相关因素。方法 2016年4月至2017年10月我院开展的微创玻璃体切除术治疗玻璃体视网膜疾病的患者217例。观察术后高眼压发生率,并对影响眼压高低的相关因素进行分析。结果微创玻璃体切除术后26眼(11.98%)发生高眼压。高眼压组术前最佳矫正视力(Log MAR)、手术时间、术后眼压高于无高眼压组;两组间前房闪辉及房水细胞分级差异有统计学意义(P0.05)。有晶体眼、人工晶体眼及无晶体眼术后高眼压发生率比较,差异无统计学意义(P=0.065)。25 g玻切术组高眼压发生率高于27 g玻切术组(P=0.026)。硅油组高眼压发生率为22.3%,灌注液组为4.7%,空气组无高眼压发生,三组间差异有统计学意义(P0.001)。糖尿病视网膜病变、眼内填充物(硅油)、术后前房闪辉及术后眼压波动是引起微创玻璃体切除术后早期高眼压的独立危险因素。结论微创玻璃体切除术后早期高眼压的发生受多种因素影响,对于手术时间长、糖尿病视网膜病变患者、眼内填充物为硅油及术后前房炎症反应重的患者尤其要重视术后早期高眼的防治。 相似文献

黄斑裂孔性视网膜脱离是一种特殊类型的孔源性视网膜脱离,是黄斑全层裂孔形成后,液化的玻璃体经此孔到达视网膜神经上皮层下而造成的,是眼科临床常见疾病[1],其发生率占孔源性视网膜脱离的10%~20%[2],较早即产生严重的视力损害,常造成视力下降、视物变形及视野缺损等.黄斑裂孔性视网膜脱离治疗较为棘手,实施手术治疗对术后视功能恢复有重要意义.自20世纪70年代开创现代玻璃体手术以来,玻璃体视网膜手术领域取得了极大的发展,微创玻璃体切割术也日益引起人们的关注[3].23 G高速玻璃体切割术是近年来发展迅速的新型微创玻璃体切割术,与传统20 G玻璃体切割术相比,具有切口小、免缝合、损伤小、手术时间短、恢复快等优点[4].我院2011年3月至2012年12月对接受23G玻璃体切割术联合内界膜剥除术治疗的20例(20只眼)特发性黄斑裂孔性视网膜脱离患者进行手术治疗,效果满意,现报道如下. 相似文献

Diagnostic cytology is a core veterinary pathology service involving specimens from domestic animals, laboratory animals, and exotic species. Evidence-based application of cytopathology involves management of preanalytical factors, and thorough evaluation of the diagnostic accuracy of the technique in each species and for all specimen types. Unique to veterinary medicine is the reliance on cytology as the basis for crucial medical decisions such as humane euthanasia, especially when the patient is critically ill or when financial considerations limit diagnostic and therapeutic options. This article reviews the cytologic criteria for the diagnosis of selected neoplastic and infectious diseases. 相似文献

Evaluation of informative value of laboratory tests and test complexes for the occupational diseases
The authors discuss the criteria for rational selection of laboratory parameters most informative for the diagnosis of occupational diseases. Such criteria as diagnostic significance, diagnostic specificity, diagnostic informative value according to Kulback (Igx), and diagnostic selectiveness ensure the optimal selection of laboratory parameters for the diagnosis of occupational diseases. Diagnostic sensitivity is not a stable value, as it depends on the disease severity and degree of exposure to harmful factors. Basic requirements, which should be taken account of when selecting the complex of laboratory methods for the diagnosis of occupational diseases, are defined. 相似文献

Direct detection of Mycobacterium tuberculosis was performed in parallel with the Amplicor M. tuberculosis test (Roche Diagnostic System, USA) and the LCx M. tuberculosis (Abbott Diagnostic Division, USA) on 697 samples, collected from 481 patients, in three different Italian laboratories. Though both systems are licensed only for pulmonary specimens, 113 extrapulmonary specimens (represented mainly by pleural fluids, cerebrospinal fluids and urines) were included in the study. Amplification results were compared with acid-fast microscopy, culture, and identification of isolates. Final clinical diagnosis was used to resolve discrepant results. M. tuberculosis was detected in 105 specimens by both assays, whereas 561 were agreeing negatives; 21 and 6 of the remaining true-positive samples scored positive with LCx only and with Amplicor only, respectively. There were three false-positives with LCx and one false-positive with Amplicor. The diagnostic sensitivity of both methods was significantly better when only respiratory specimens were considered (78% versus 59% in nonrespiratory samples with Amplicor, and 88% versus 65% with LCx). Our data reveal a significantly better sensitivity of the LCx (p = 0.026) and a slight better specificity of the Amplicor assay. It is noteworthy that 16 of the 21 Amplicor-negative specimens in which LCx detected M. tuberculosis were culture negative, thus suggesting that the higher diagnostic sensitivity of the latter assay is attributable to its better analytical sensitivity. However, the majority of such samples originated from patients under antimicrobial treatment, which makes uncertain the clinical significance of such increased sensitivity. Considering true-positive for LCx and true-negative for Amplicor, the 16 culture-negative/LCx-positive/Amplicor-negative specimens resulted true-positives after the resolution of discrepancies, the final overall sensitivity and specificity values of the LCx assay were not significantly different from the ones of the Amplicor assay. 相似文献

Functional genomics and proteomics involve the simultaneous analysis of hundreds or thousands of expressed genes or proteins and have spawned the modern discipline of computational biology. Novel informatic applications, including sophisticated dimensionality reduction strategies and cancer outlier profile analysis, can distill clinically exploitable biomarkers from enormous experimental datasets. Diagnostic pathologists are now charged with translating the knowledge generated by the "omics" revolution into clinical practice. Food and Drug Administration-approved proprietary testing platforms based on microarray technologies already exist and will expand greatly in the coming years. However, for diagnostic pathology, the greatest promise of the "omics" age resides in the explosion in information technology (IT). IT applications allow for the digitization of histological slides, transforming them into minable data and enabling content-based searching and archiving of histological materials. IT will also allow for the optimization of existing (and often underused) clinical laboratory technologies such as flow cytometry and high-throughput core laboratory functions. The state of pathology practice does not always keep up with the pace of technological advancement. However, to use fully the potential of these emerging technologies for the benefit of patients, pathologists and clinical scientists must embrace the changes and transformational advances that will characterize this new era. 相似文献

Rationale, aims and objectives Diagnostic errors and delays carry potentially grave consequences for patients and feature prominently in studies of adverse events in health care. Diagnostic errors present a particular challenge for error/incident reporting systems because they involve clinical reasoning and are difficult to define precisely. The aim of the present study was to investigate what insights can be gained about diagnostic error from an incident reporting system. Methods Diagnostic errors reported to the UK's National Reporting and Learning System (NRLS) between November 2003 and October 2005 were investigated. We analysed reported level of harm to the patient and incident location and we compared diagnostic with non‐diagnostic incidents. We also assessed the quality of reporting in a subset of reports associated with a patient's death. Results Of 316 589 incidents reported in the period under investigation, 1674 were diagnostic (0.5%). Diagnostic incidents were more likely than other incidents to be associated with moderate or severe harm, or a patient's death and were more likely to occur in a hospital emergency department than other incidents. Diagnostic incidents in emergency departments were more likely to be associated with greater harm than similar incidents in wards. Observed reporting quality (detail; clarity) was very variable. Conclusion These findings replicate findings from studies in emergency departments and suggest that reporting systems have a role to play in understanding diagnostic errors alongside other sources of error analysis. Accurate and complete reporting of adequate volume enhances the potential contribution of an incident reporting system to understanding diagnostic error. 相似文献
