作者： Mohamed Ahmed Sabry Said Shalaby montaser Cardiology Department National Heart Institute Giza Egypt Cardiology Department Faculty of Medicine Menoufiya University Shebien El Kom Egypt

Background: Percutaneous mitral balloon valvuloplasty is the main procedure in mitral stenosis (MS). It can replace surgical commissurotomy in many cases;however, mitral regurgitation (MR) remains the major procedure complication. Objectives: This study was conducted to investigate predictors of MR as a complication followingpercutaneous mitral valvuloplasty (PMV) using multitrack balloon technique. Methods: This cohort study was conducted at both Menoufia University Hospital and Mabaret Misr Elkadima Hospital. We enrolled 121 patients with moderate to severe MS who were subjected to PMV using multitrack balloon technique during the period from October 2017 to October 2019. Transthoracic echocardiographic evaluation was performed for all patients before and after the procedure. Patients who developed severe MR post procedure were compared with other patients to identify important distinction points. Results: Most patients (N = 109, 90.1%) developed no/mild MR (group A), whereas 12 (9.9%) patients developed severe MR

Bronchotomy as a Safe and Feasible Alternative to Failed Bronchoscopic Removal of Foreign Body Inhalation in Pediatrics. A Seven-Year Review

引用

Open Journal of Thoracic Surgery 2021年第2期11卷 47-57页

作者： montaser Abd Elaziz Mohammed Eltaweel Mohamed Elsayed Mohammed El-Hag-Aly Cardiothoracic Surgery Department Faculty of Medicine Menoufia University Al Minufya Egypt Faculty of Medicine Jazan University Jazan KSA

Background: Aspiration of foreign body is popular in pediatric age group and is considered as an important cause of respiratory distress and chocking in these children. Management strategies are different according to the mode of presentation. This study aims to assess the efficacy of rigid bronchoscopy and the role of bronchotomy as a safe alternative for failed removal of inhaled foreign body. Methods: We enrolled 254 patients with foreign body aspiration (FBA) up to 14 years old in a retrospective observational study. Our patients were reviewed from the Cardiothoracic Surgery Department and cases referred from Otorhinolaryngology Department, Menoufia University Hospital between June 2010 and July 2017. Using jet ventilation technique, foreign body was removed by the rigid bronchoscopy with either extracting forceps or postural drainage. Surgical interference such as bronchotomy needed in distally impacted foreign bodies (FBs). Results: Our study included 254 patients prepared for bronchoscopic FBs extraction. Most of cases (68.8%) presented early within first week (174 cases). No FBs detected in 44 cases by rigid bronchoscopy, although it was successful in 176 (69.5%) cases with non- impacted inhaled FBs. 14 cases only needed postural drainage due to inaccessible FBs, another 12 cases failed to extract FB with rigid bronchoscopy but they were managed with flexible bronchoscopy. Bronchotomy was needed for impacted FBs in eight cases (3%). Conclusion: This study’s findings support that rigid bronchoscopy is the gold standard in the diagnosis and removal of foreign body aspirations in pediatrics, but rigid bronchoscopy demonstrated less capability in the diagnosis and removal of small distally located foreign bodies. Bronchotomy is safe and effective alternative.

引用

World Journal of Cardiovascular Diseases 2018年第12期8卷 557-568页

作者： Mahmoud Kamel Ahmed Emara Said Shalaby montaser Mahmoud Said Menufia University Hospital Shibin El Kom Egypt

Objective: Early detection of LV mechanical abnormalities in patients with cardiac syndrome X (CSX) by speckle tracking echocardiography (STE). Background: Cardiac syndrome X is a triad of angina pectoris, positive stress test for myocardial ischemia and angiographically free coronary arteries. Two dimensional speckle tracking?echocardiography (2D-STE) provides a more sensitive method for evaluation of global and segmental LV function than conventional two dimensional echocardiographic parameters. Subjects and Methods: Seventy patients proved to have CSX and 20 healthy control volunteers were included with a mean age of 49.43 ± 5.92 vs. 49.40 ±6.27 years respectively with no difference regarding sex for both patients and controls. Patients with hypertension, diabetes mellitus, valvular heart disease, cardiomyopathies, inflammatory diseases, myocarditis and arrhythmias were excluded. All included individuals were subjected to complete conventional echocardiographic assessment and left ventricular global and segmental mechanical function was assessed using 2D based strain and strain rate (longitudinal, radial and circumferential) imaging. Results: There was no statistically significant difference in LV conventional echo parameters between patients and controls. However, global mean longitudinal strain was significantly lower in patients than controls (-15.05 ± 3.28 vs. -20.22 ± 2.49;p 0.001). For radial and circumferential strain stain, there was no significant changes between patients vs. controls (29.75 ± 18.26 vs. 28.09 ± 15.48;p = 0.74) and (-19.88 ± 8.63 vs. -21.93 ± 5.69;p 0.05) respectively. Conclusion: In spite of normal conventional echo parameters among patients and controls, LV longitudinal strain and strain rate by 2D speckle tracking imaging were lower in the patients denoting subclinical left ventricular mechanical dysfunction in patients with CSX.

作者： montaser M. Mohamed Rasha A. Ali Mohammed N. Hamdoon Faculty of Medicine Sohag University Sohag Egypt

Background: Diabetic peripheral neuropathy (DPN) is a common complication among children with TIDM and is related to poor glycemic control. The aim of the study is to determine prevalence and determinants of diabetic neuropathy in diabetic children. Material& Methods: This is a cross sectional study conducted on 50 children having Type I diabetes mellitus for more than year presented to Pediatric Neurology and Endocrinology Outpatient Clinics, Sohag University Hospital, Sohag, Egypt, during one year duration (2017). Children were subjected to detailed neurological examination and electrophysiologic studies in addition to recording of socio demographic and laboratory findings with special regard to level of HbA1c. Results: The mean age of the studied children was 10.5 ± 0.3 years ranging from 5 to 18 years. 22 cases (44%) were younger than 10 years, 27 children (54%) were females. DPN was diagnosed in 12% of the studied children. No significant relation was found as regard age, gender, family history, consanguinity and duration of the diseases. Significant association was found between the HbA1c level and development of DPN in the studied children. Conclusion: Based on the results of this study, 12% of the studied diabetic children had DPN of whom more than 16% had subclinical neuropathy indicating the need for annual screening of neuropathy using Nerve Conduction Study. Moreover strict glycaemic control is needed to prevent rapid development of diabetic among these children.

Preliminary molecular variability among haplotypes of Saudi Arabian house sparrow <i>Passer domesticus</i>

引用

Open Journal of Ecology 2011年第3期1卷 73-76页

作者： Sayed A. M. Amer Metwally M. montaser Mohammed Shobrak 不详

Genetic variability of Passer domesticus from different localities of Saudi Arabia was investigated. Six hundred and fifty nine nucleotides were sequenced from the mitochondrial cytochrome b gene. There was a slight difference among the studied haplotypes and most substitutions were synonymous. In some haplotypes at the west of Arabian Peninsula (mountainous habitat), two transitions only were non-synonymous. The data were used to construct the relationship of the Arabian house sparrow to its con specific taxa from Europe and America. Neigh-bor-joining (NJ), maximum-par-simony (MP) and maximum-likelihood (ML) analytical methods were used. The three methods showed clustering of the Arabian haplotypes in one group and their sister relationship with the haplotypes from Netherlands and America. A spanish Haplotypes came basal to both groups. Collecting more samples and more DNA data could be of necessary to clearly address the genetic variability of this rapidly propagated species in Arabia.

Introduction: Anterior ST-segment elevation myocardial infarctions (STEMI) are those involving the anterior ECG leads of the heart as a result of transmural ischaemia. They can be subdivided according to their extension into anteroseptal and anterolateral infarctions. Objective: The aim of this study is assessment of right ventricular function using strain and strain rate imaging in patients with anterior ST segment elevated myocardial infarction (STEMI). Methods: This prospective study was conducted on 35 patients with anterior ST segment elevated myocardial infarction (STEMI) who were admitted to ER and CCU department in National Heart Institute from May 2018 to May 2019. Results: Comparison between groups regarding longitudinal strain showed that there is highly statistically significant difference between them in lateral wall (all segments), septum (all segments) and global LS of right ventricle. Comparison between studied groups regarding circumferential strain revealed that there is highly statistically significant difference between them in all segments of right ventricle. Conclusions:Strain and strain rate imaging are feasible and reproducible tools in assessment of right ventricular function in patients with anterior ST segment elevated myocardial infarction (STEMI).

引用

Open Journal of Thoracic Surgery 2022年第2期12卷 21-32页

作者： montaser Elsawy Abd Elaziz Eman Gomaa Saleh Mohamed Gaber Elsayed Bassem A. Hafez Cardiothoracic Surgery Department Faculty of Medicine Menoufia University Menoufia Egypt Faculty of Medicine Jazan University Jazan Saudi Arabia Neuropsychiatry Department Faculty of Medicine Menoufia University Menoufia Egypt

Background: The aim of this study is to assess the necessity of temporary cardiac pacing and identify the predictors of pacing after coronary artery bypass graft (CABG). Methods: This was a retrospective observational study of 150 patients who had isolated CABG between November 2013 and December 2021. Patients were classified into two groups: group A, (n = 135) who did not need to be paced and group B, (n = 15) who needed temporary epicardial pacing. Only 10% (15/150) of patients in the study needed pacing. The primary outcome variable was assessment of the need for postoperative temporary cardiac pacing (TCP) (patients were paced during chest closure or at any time during hospital admission). The incidence of pacing during the postoperative period was observed. Univariate and multivariate predictors for postoperative pacing were determined and specicific predictors for cardiac pacing were found. Results: In both univariate and multivariate analysis, Old age > 65 years, diabetes mellitus, pacing to come off cardiopulmonary bypass (CPB), CPB time > 100 min, cardioversion to leave OR, antiarrhythmics to leave OR and new onset of atrial fibrillation (AF), were found to be significant predictors for the need to cardiac pacing. Conclusion: After coronary artery bypass surgery, a small percentage of patients require TCP. We emphasize unique predictors for postoperative pacing in this study.
