Technical considerations of computer-aided planning in severe orbital trauma: A retrospective study.

The aim of this study was to evaluate the clinical outcomes of linear and orbital volume measurements in severe orbital trauma. Patients with severe orbital trauma that involved more than two walls and entailed a marked degree of comminution were included in this retrospective analysis. However, patients with incomplete clinical records and a simple blowout or zygmatico-orbital fractures were excluded.

One-Piece Fronto-orbital Distraction With Midline Splitting But Without Bandeau for Metopic Craniosynostosis: Craniometric, Volumetric, and Morphologic Evaluation.

Background: Distraction osteogenesis has gained popularity in the treatment of different types of craniosynostosis. We aimed to present the technique of 1-piece fronto-orbital distraction with midline splitting osteotomy but without bandeau for the treatment of metopic craniosynostosis, and the protocol of outcome evaluation using craniometric, volumetric, and morphologic parameters based on 3-dimensional computer simulation.

Methods: This retrospective study included 9 patients with isolated metopic craniosynostosis who underwent surgical correction with distraction osteogenesis between December 2015 and February 2018.

Evaluation of virtual surgical plan applicability in 3D simulation-guided two-jaw surgery.

Background: Three-dimensional (3D) simulation-based orthognathic surgery is becoming a more popular technique. Therefore, standardized methods for evaluating the efficacy and reliability are required. The virtual surgical plan (VSP) applicability, which represents the degree of similarity between planned movements and actual surgical events, should be accurately measured as a separate entity.

Surgery for Active Infective Endocarditis of the Aortic Valve With Infection Extending Beyond the Leaflets.

Background: The optimal aortic substitute in extensive aortic valve active infective endocarditis (AIE) continues to be debated. To determine the surgical approach in aortic valve AIE with infection extension beyond the leaflets, we evaluated the outcome of reconstructive surgery with various valve substitutes in those patients.

Methods: During 2000-2013, 168 patients had surgery for extensive aortic valve AIE.

Molecular differentiation and phylogenetic analysis of the Egyptian foot-and-mouth disease virus SAT2.

In February 2012, a massive new foot-and-mouth disease (FMD) outbreak struck Egypt. In this work, one-step RT-PCR assays were used for in-house detection and differentiation of foot-and-mouth disease virus (FMDV) in Egypt in this year using pan-serotypic and serotype-targeting sequence primers. FMDV SAT2 was the dominant virus in the examined isolates from the epidemic.

HLA class I and class II HLA DRB profiles in Egyptian children with rheumatic valvular disease.

Poststreptococcal sequelae, especially acute rheumatic fever/rheumatic heart disease continues to occur in significant proportions in many parts of the world, especially in less developed countries. An important factor in the study of rheumatic heart disease is the human genetic susceptibility to the disease. The aim of the present study was to detect the most prevalent HLA class I and class II types associated with risk of rheumatic heart disease in Egyptian children.
