Alagille syndrome(ALGS;OMIM#118450)is a highlyvariable,multi-systemic,autosomal dominant disorder,caused by mutations in the Jagged Canonical notch Ligand 1(JAG1)gene(20p12.2)or in the neurogenic locus notch homolog protein 2(nOTCH2)gene(1p13).^(1)It primarily affects the liver,heart,eyes,face,kidney,skin,vertebrae,and skeleton.^(1,2)The JAG1 gene has 26 exons and about 90%of the ALGS cases result from pathogenic variants in the JAG1 and around 7%of cases have deletions in chromosome 20 that include this gene.

Reconstructive surgery for phantom and residual limb pain in post-conflict settings

引用

Chinese Journal of Plastic and Reconstructive Surgery 2024年第1期6卷 54-55页

作者： Damián Palafox Plastic and Reconstructive Surgery Department Hospital Angeles Puebla

Traumatic amputations remain one of the most frequent and disturbing wounds of armed conflict. In this scenario,most amputees develop residual and phantom limb pain, impacting their quality of life. There are several elective surgical procedures available for both conditions, such as neuroma excision followed by nerve reconstruction,nerve relocation, e.g., surgically implanting a transected nerve into a muscle, nerve transfers in cases of associated paralysis, and most recently, regenerative peripheral nerve interface surgery. Whenever possible in the postconflict phase, a coordinated effort between traveling humanitarian surgeons specializing in reconstructive microsurgery and local healthcare providers is essential for successfully treating phantom and chronic residual limb pain in post-conflict amputees. While providing a detailed logistical framework for global humanitarian missions is beyond the scope of this article, we provide a brief perspective on a topic of utmost importance for reconstructive surgeons worldwide: the high-quality care and treatment of refugees and those whose lives have been impacted by conflict, disaster, or displacement.
