“…Anecdotal reports with small patient numbers have documented its selected use and immediate success. 26 , 50 , 51 Complications of this modality include stent-graft sepsis, occlusion, endoleaks and missed opportunistic infections. 4 , 52 Scholtz 53 has raised concerns about this modality, from a radiological perspective, with regard to angiographic access, small-calibre vessels and contrast pooling in the multiple aneurysms.…”

An established relationship exists between human immunodeficiency virus (HIV) and the vascular system, which is characterised by clinical expressions of aneurysmal and occlusive disease that emanate from a common pathological process. The exact pathogenesis is currently unknown; attempts to implicate opportunistic pathogens have been futile. Theories converge on leucocytoclastic vasculitis with the vaso vasora as the vasculopathic epicentre. It is thought that the virus itself or viral proteins trigger the release of inflammatory mediators that cause endothelial dysfunction and smooth muscle proliferation leading to vascular injury and thrombosis. The beneficial effects of highly active anti-retroviral therapy alter the natural history of the disease profile and promote longevity but are negated by cardiovascular complications. Atherosclerosis is an emerging challenge. Presently patients are managed by standard surgical protocols because of non-existent universal surgical interventional guidelines. Clinical response to treatment is variable and often compounded by complications of graft occlusion, sepsis and poor wound healing. The clinical, imaging and pathological observations position HIV-associated large-vessel vasculopathy as a unique entity. This review highlights the spectrum of HIV-associated large-vessel aneurysmal, occlusive and atherosclerotic disease in vascular surgical practice.

“…The effect is more visible within the first four days of treatment. Aside from inhibiting normal infection resistance, after four days steroids have almost imperceptible effect 38 . According to Branski et al 39 , the acute stage of the healing process is critical.…”

Os corticosteróides são potentes inibidores da inflamação e da cicatrização. Administração local de esteróides diretamente na laringe tem sido relatada em diversas patologias laríngeas. OBJETIVO: O objetivo desse estudo é realizar uma revisão da literatura sobre o uso de infiltração de corticosteróide em pregas vocais, em pacientes com patologias vocais benignas, inflamatórias e crônicas de laringe. METODOLOGIA: Realizou-se uma busca eletrônica na base de dados Medline, selecionando-se estudos clínicos que utilizavam corticosteróides em patologias benignas da laringe. RESULTADOS: Os corticosteróides são indicados nas seguintes situações: 1) doenças inflamatórias agudas, principalmente naquelas relacionadas a edema que comprometa a via aérea; 2) doenças auto-imunes com alterações laríngeas; 3) estenose laríngea; 4) em lesões benignas inflamatórias das pregas vocais, como nódulos, pólipos e edema de Reinke, para diminuir o processo inflamatório pré-cirúrgico ou na tentativa de se evitar uma intervenção cirúrgica; 5) em fonocirurgia, com o objetivo de reduzir a formação de cicatriz. Seu uso pode ser profilático, visando à prevenção da formação de cicatriz ou terapêutico em uma cicatriz já formada. CONCLUSÃO: Os corticosteróides podem ser considerados uma opção terapêutica importante no manejo de várias patologias, principalmente aquelas de origem inflamatória que causam alterações vocais.

“…The development of vasculitis and arterial aneurysms in the setting of HIV infection has been well described. [3][4][5] Calabrese et al 6 described 14 cases of acquired immunodeficiency syndrome vasculitis, 5 defined as having angiocentric immunoproliferative features attributed to autoimmune mechanisms and the remaining 9 having regions of necrotizing vasculitis with aneurysm formation from intraluminal thrombosis or focal vessel wall infection.…”
