A set of parametric studies by using the Abaqus software is conducting to investigate the effective method to seal the CWO sewer from the tunneling process. These methods include: (i) two deep grouted walls, (ii) adjacent slurry piles, (iii) bored reinforced concrete piles assisted with slurry piles, and (iv) grouted block confining the twin tunnel wall. Based on the results of parametric studies. Most of the protective studied technique was effective on reducing the tunneling effect on the ground movements. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the correlation between the diffusion tensor imaging (DTI) measures and the reading, spelling, writing, rapid naming, memory, and motor abilities in Arabic dyslexic children. This could verify the influence of possible white matter alterations on the abilities of those children. Methods: Twenty native Arabic-speaking children with dyslexia (15 males and 5 females; 8.2 years ± 1) underwent DTI of the brain on 1.5 T scanner. Diffusion-weighted images were acquired in 32 noncollinear direction. Tractography of the arcuate fasciculus (AF) was performed. Region of interest (ROI)-based approach was also used. Regions encompass superior longitudinal fasciculus (SLF), anterior and superior corona radiata (CR), and posterior limb of internal capsule (PLIC) were analyzed. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured. The aptitudes of those children were evaluated by the dyslexia assessment test. These abilities were statistically correlated with the FA and ADC of the AF and other ROIs. Results: The reduction of FA of right AF was related to worse overall reading and related abilities performance. The ADC of right SLF was negatively correlated with memory abilities. The ADC of right PLIC was positively correlated with writing performance. Other relations were also found. Conclusion: White matter microstructural DTI measurements in the right AF, right PLIC, SLF, and left anterior and superior CR are correlated to reading, spelling, writing, memory, and rapid naming abilities of the participants. The DTI measures could be promising regarding their use as a biomarker for follow-up in developmental dyslexia. [ABSTRACT FROM AUTHOR]

Background: Pain that pursues coronary artery bypass graft (CABG) surgery is usually associated with increased both recovery duration and hospital stay. Patient outcome could be worsened owing to large doses of opioids for pain control through over sedation, and prolonged mechanical ventilation. This study was designed to evaluate the effect of preemptive gabapentinoids on post CABG surgery pain control. Objective: to evaluate the effect of pre-operative administration of pregabalin and gabapentin in limiting the post-operative pain in coronary artery bypass surgeries. Patients and Methods: Type of Study: Prospective double – blinded, randomized controlled Trial. After Approval is obtained from the research ethics committee of anesthesia and intensive care department, Ain Shams University. Study Setting: National Heart Institute, Egypt. Study Period: 6 months. Study Population: adult undergoing coronary artery bypass graft surgeries. Results: The primary outcome of this study was to compare the effect of gabapentinoids on post CABG pain as reflected by morphine consumption. The secondary outcome was to address the influence of gabapentinoids on patient satisfaction post CABG, Background: Pain that pursues coronary artery bypass graft (CABG) surgery is usually associated with increased both recovery duration and hospital stay.

Objective: The aim of this study was to describe average nasal anthropometric measurements for young Egyptian males by using the Rhinobase ® software., Materials and Methods: This was a cross-sectional study involving the evaluation of facial photographs. Frontal, right lateral and basal photographs for 300 healthy adult male Egyptian volunteers (n = 300) were taken; then, the photos were edited using Rhinobase ® Software and CorelDraw graphics (2017) software. Twenty anthropometric landmarks were determined. The calculated measurements of the soft tissue of the external nose included ten linear measurements and five angles., Results: The means of the linear measurements of the external nose in this study were as follows: nasal height (56.12 mm), nasal bridge length (47.0 mm), columella length (9.1 mm), alar length (29.3 mm), morphological nose width (41.0 mm), anatomical nose width (38.0 mm), nasal tip protrusion (21.0 mm), nasal tip projection using 'Goode's method' (29.36 mm), dorsum width (9.6 mm) and nasion height (2.04 mm). The means of the angular measurements of the nose were as follows: nasofacial angle (33.1°), nasofrontal angle (144.0°), nasolabial angle (104.5°), nasomental angle (127.6°) and mentocervical angle (104.7°)., Conclusions: Racial differences of the external nasal anthropometric values exist; hence, it is important to establish the average anthropometric measures for several races and ethnic groups. Measurements collected in this study can serve as a database for anthropometric average values of the external nose in healthy adult Egyptian males. Moreover, these measurements can aid in planning prior to nasal reconstruction and esthetic rhinoplasty by serving as a reference standard. Although the Rhinobase ® software is an easy, reliable and safe indirect method for nasal analysis, we should be cautious during interpretation of some edited landmarks on Rhinobase ® software pictures. In addition, inserting two rulers (in the horizontal and vertical dimension) allows accurate assessment of the linear anthropometric measurements., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.
