目的:评估B超在不同性质眼后段异物大小测量中的准确性。
方法:回顾性分析2016-01/12在我院被诊断为眼后段异物的患者13例13眼。异物在取出后用直尺测量实际大小,并同术前B超所测数值进行比较,同时计算相关系数(B超测量值/实际大小)。为了排除手术操作损伤异物对真实大小测量的影响,选定长度为5mm的不同材质物体(分别为金属、玻璃和木质)放入直径约20~30mm的水囊中模拟眼内异物,同样进行以上的测量,测量重复4次。
结果:选取13眼内异物均经玻璃体手术完整取出,其中金属磁性异物12眼,玻璃异物1眼。12个金属异物术前B超所测长轴和实际长度的平均值分别为3.65±1.30和2.45±0.94mm,所有测量值均大于实际值(P=0.016)。相关系数的平均值为1.49。体外实验中,金属、玻璃和木质三种不同性质异物B超的平均测量值分别为6.76±0.15、6.55±0.04和6.02±0.07mm,相关系数分别为1.35、1.31和1.20。
结论:B超用于眼后段异物测量时,其所测量值会大于真实大小,尤其是对于金属和玻璃异物。因此在术中制作异物取出切口时需要进行考虑。 相似文献

Purpose: To report a critical case series of five patients with posterior microphthalmos and the review of their clinical findings with the analyses of retinal imaging. Method: Case series. Complete ophthalmological examinations including optical coherence tomography (OCT) were evaluated. Results: All patients had decreased visual acuity with high hyperopic refraction. Dilated fundus examination demonstrated that elevated papillomacular retinal folds with anterior segment were unremarkable. Total axial lengths measurements showed reduced axial lengths and B-scan ultrasonography revealed sclerochoroidal thickening. Moreover, papillomacular folds were confirmed by OCT. Conclusion: Dilated fundus examination, fundus fluorescein angiography, orbital ultrasonography, and proper OCT evaluation will be helpful to reach a diagnosis. 相似文献

Objectives: Systemic mastocytosis (SM) is a myeloproliferative disease characterized by the accumulation of aberrant mast cells. Since advanced subtypes of SM can lead to organ dysfunction and shortened survival, timely recognition of progressive disease is important for the adequate treatment of SM patients.Methods: Here, we report the results of our cohort study on the value of routine abdominal ultrasonography for the detection of progression of indolent systemic mastocytosis (ISM).Results: We included 88 patients with ISM, of whom 9 developed new hepatosplenomegaly during follow-up. In this group, the median serum tryptase level increased by 11.60?μg/l, compared with a decrease of ?0.20?μg/l in the 79 patients with unchanged ultrasonography results (p?=?0.016). A change in liver and/or spleen size never led to a change in clinical classification, nor management.Discussion: Based on the finding that a change in ultrasonography findings did not correlate to disease progression in general, it appears that isolated hepatosplenomegaly does not have prognostic implications in patients with ISM.Conclusions: Routine abdominal ultrasonography is redundant in the follow-up of patients with ISM. A combination of physical examination with serum tryptase levels can be used to screen for hepatosplenomegaly. 相似文献

目的探讨山莨菪碱联合安定用于超声内镜检查的价值及护理配合方法。方法选择2014年8月~2016年8月本院收治的食管胃内黏膜下病变实施超声内镜检查者80例,按照随机数字法分两组,各40例,所有入组者均行相应护理干预,其中对照组使用安定,观察组联合使用山莨菪碱,比较两组检查期间血氧饱和度变化情况及总检查时间,统计两组检查过程中的不良反应。结果观察组血氧饱和度显著高于对照组(P0.05),总检查时间显著短于对照组(P0.05),观察组发生咳嗽、憋气及呕吐总发生率显著低于对照组(P0.05)。结论行内镜超声检查时使用山莨菪碱联合安定治疗,能更有效地维持患者血氧饱和度,缩短检查时间,减少检查过程导致的不良反应。 相似文献

Objective: Only few determinants of gallstone formation have been identified in cohort studies. The aim was to identify further determinants for gallstones in a Danish cohort and to perform a meta-analysis of results from existing cohorts.Material and methods: Data from a cohort study was used. Gallstone incidence was assessed through repeated ultrasound examinations. Body mass index (BMI), blood pressure, self-rated health, lifestyle variables, blood lipids, and use of female sex hormones were measured at the baseline examination. Statistical analyses included logistic regression. Based on a prospective protocol, a systematic review of the literature was performed identifying all articles dealing with determinants of incident gallstones. Meta-analyses of comparable determinants were performed through fixed effect models.Results: Participants with no gallstones at baseline and with at least one re-examination were followed-up completely (mean 11.6 years, N?=?2848). The overall cumulative incidence of gallstones was 0.60% per year. Independent positive determinants for incident gallstones were age, female sex, non-high density lipoprotein (non-HDL) cholesterol, and gallbladder polyps. In addition, BMI was positively associated in men. The systematic review additionally identified associations for comorbidities, parity, and dietary factors. Meta-analysis confirmed the significant associations for incident gallstones and age, female sex, BMI, and non-HDL cholesterol. No significant associations were found for blood pressure, smoking, alcohol consumption, HDL cholesterol, or triglycerides in meta-analyses.Conclusions: Age, female sex, BMI, non-HDL cholesterol, and polyps are independent determinants for gallstone formation. Incident gallstones and the metabolic syndrome share common risk factors. More studies are needed for further exploration. 相似文献
