Objective: To study the effect of cerebral ischemic vascular insult on the localization of language areas as regard to automatic speech, initiation, and mutism. Materials and Methods: Seventy ischemic stroke patients were selected within the first 48 h of the onset of stroke with left hemispheric stroke with aphasia. Inclusion criteria: any age above seven years, both sexes, first ever clinical stroke, admitted within the first 2 days of stroke insult. Patients underwent careful history taking, neurological examination, routine laboratory investigations, echo cardiography, and carotid duplex and language assessments. Results: Automatic speech disorders were mainly seen along left insular, left supramarginal and left frontal inferior orbital lesions. Initiation difficulty is seen mainly along as left insular, left temporal superior and left periventricular lesions. Mutism is seen along left external capsule, left internal capsule, left pallidum, left frontal inferior orbital and left inferior trigone lesions. Conclusions: Deep periventricular white matter and insular area in the dominant hemisphere play an important role in many language tasks. Thus aphasia is not a mere cortical function.

This paper devoted to propose template match object detection for inertial navigation systems (INS). The proposed method is an image processing technique to improve the precision of the INS for detecting and tracking the ground objects from flying vehicles. Template matching is one of the methods used for ground object detection and tracking. Robust and reliable object detection is a critical step of object recognition. This paper presents a proposed mathematical morphological template matching method for detection and tracking of ground objects. Our focus is on flying systems equipped with camera to capture photos for the ground and recognize it. The proposed method is independent on the altitude or the orientation of the object. The algorithm is simulated using Matlab program and the numerical experiments are shown which verify the object detection for a wide range altitude and orientation. The results show superiority of this method for identifying and recognizing the ground objects.

Background: The surgery of cerebellopontine angle tumours has remarkably progressed over the last 2 decades due to improved microsurgical techniques. The primary operative goals are microscopic total removal of the tumour while securing the adjacent cranial nerves. Facial Nerve plays a critical role in facial muscles function and one’s cosmetic appearance, and its weakness can have profound implications on a patient’s quality of life. Aim of the Study: To assess the impact of monitoring techniques on the preservation of facial nerve function during cerebellopontine angle tumours surgery. Patients and Methods: This is a prospective study. This study was conducted on 30 cases (2 groups, each had 15 patients) with CPA lesions that had undergone surgical excision of these lesions performed by retrosigmoid approach (Group A: the patients were operated under continuous intraoperative facial nerve monitoring (IOFNM) and Group B: the patients were operated without IOFNM). They were operated upon in neurosurgery departments at Al-Azhar university hosp

Background: Patients with ischemic heart disease and reduced ejection fraction have increased risk for postoperative complications and mortality. Our aim was to evaluate the effect of low EF (on the early outcomes after CABG and identify the predictors of mortality. Methods: From August 2018 to November 2019, 170 consecutive patients underwent CABG. Group 1 included 120 patients with EF ( EF (>40;57.90% ± 2.27%), 41 were men (82.0%), and the mean age was 54.30 ± 7.01 years and used as a control group. Results: Overall 30-day mortality was 10/120 patients (8.3%). Factors associated with higher mortality were females (70.0% vs. 17.3%, P Conclusion: CABG in EF < 40% is associated with more complications compared with those had EF higher than 40%;however, the clinical and echocardiographic parameters improved over time.
