ABSTRACT
Objective: It was aimed at investigating the role of lung ultrasonography in assessment of pneumonia as compared to chest x-ray in pediateric age group
Purpose: to evaluate the ultrasound efficiency in the assessment of pneumonia in pediatric age group as compared to chest x-ray
Methodology: This study was carried out at the general pediatric wards and PICUs of El-Demrdash hospital, Ain Shams University.40 patients were clinically diagnosed with pneumonia. For every child included in the study, a chest x-ray and a chest US were performed
Result: the detection rate of consolidative patches was higher in ultrasound compared to the x-ray technique
Conclusion: Lung ultrasound is safe and accurate for the diagnosis suspected cases of community acquired pneumonia and it is more sensitive than chest X-ray and allows a radiation free technique for detection of consolidations in children, thus reducing radiation exposure in this population
ABSTRACT
Background: Lower limb peripheral arterial disease [PAD] is a common disease that affects about two hundred million peoples per year. It is the third leading cause of cardiovascular morbidity. We plan to evaluate the diagnostic performance of 64-section computed tomographic [CT] angiography in the assessment of steno-occlusive disease in patients with PAD, with conventional digital subtraction angiography [DSA] as the reference standard
Aim of study: is to compare the diagnostic accuracy of multidetector computed tomographic [MDCT] angiography in diagnosis of PAD compared to the DSA as pre-operative evaluation of lower limb peripheral arterial diseases
Patients and methods: The study included 20 patients clinically presented with symptomatic PAD from February 2018 to July 2018. The study protocol was approved, and written informed consent was obtained from all patients. The patients underwent CT angiography and subsequent DSA. For stenosis analysis [>/=70% stenosis], the arterial bed was divided into 35 segments and evaluated by three readers. Inter observer agreement was determined with generalized Kappa statistics. Accuracy, sensitivity, specificity, was calculated. Mc Nemar test was used to prove significant differences between CT angiographic and DSA findings
Results: A total of 700 arterial segments were evaluated, with excellent agreement between readers [Kappa >/= . 0.928]. On a segmental basis, both sensitivity and specificity for stenosis of 70% or more were at least 96% [386 of 400 segments and 290 of 300 segments, respectively], with an accuracy of 98% [686 of 7oo segments].There was no significant difference between CT angiographic and DSA findings [P = .62-.87]
Conclusion: The diagnostic performance of 64-section CT angiography is excellent in patients with clinical symptoms of PAD
ABSTRACT
Background: lung ultrasound is a part of the diagnostic armamentarium in Resuscitation and Recovery Units with an enormous potential due to its advantages capacity to diagnose more precisely than conventional radiology, earlier diagnosis, convenience due to being able to perform at the bedside, possibility of being performed by one person, absence of ionizing radiation and due to its dynamic character
Aim of the Work: this study aimed to assess the impact of chest ultrasonography in detecting, differentiation and management of the different pleural diseases
Patients and Methods: this prospective study included 50 patients who were presented with suspected clinical and/or radiological evidence of pleural disease in the Chest Department of Demerdash Hospital, during the period between November 2014 and June 2017. Patients with pleural diseases with lung involvement were excluded
Results: US were more statistically significantly sensitive and specific in the detection of pleural effusion compared to chest radiography. A sensitivity of 0.92 for US examination against 0.74 for chest radiography in detection of pleural thickening was noted. There were no statistically significant differences between the sensitivity and specificity of chest US and chest CT in detection of different pleural pathologies
Conclusion: US are an efficient and suitable method for the evaluation of different pleural diseases in critically ill patients in the RICU. US are mostly sensitive and specific in diagnosing pleural effusions. US-guided diagnostic and therapeutic pleural interventions are successful in achieving their goal with favorable outcomes and minimal complications
Recommendations: US accessibility was difficult for some patients because of tissue edema, subcutaneous emphysema and obesity. Thus further studies are needed in order to generalize these results
ABSTRACT
Previous investigation indicated that adding of 10-15 wt% iodine polymer could render the zinc polycarboxylate cement disinfectant. This modification had also no significant effect on the cements setting characteristics. The current study aimed to evaluate the physico-mechanical properties of the zinc polycarboxylate cement after modifying its powder by adding 10, 12.5 and 15 wt% iodine polymer [povidone iodine]. The modified cement was tested for the compressive strength, diametral tensile strength, film thickness and solubility. All the evaluating tests were adopted from the ANSI/ADA specifications no. 96. Statistical analysis of the results using both one-way analysis of variance [ANOVA] and student t-test revealed no significant change in both compressive and tensile strengths [t-test. P= 0.0269 and 0.3253] when the cement is modified by 10 wt% iodine polymer. The same modification ratio had also no significant effect [t-test. P= 0.0249] on the solubility of set cement. All the modifying ratios under investigation recorded no significant effect [ANOVA, P> 0.05] on the film thickness of the polycarboxylate cement. Depending on those results the following conclusion could be drawn: Modifying the polycarboxylate cement powder by adding 10 wt% iodine polymer has no adverse effect on the cement's physico-mechanical properties
