Myositis, Vasculitis, Hepatic Dysfunction in Adult-Onset Still's Disease

Emergency Mechanical Thrombectomy for Acute Middle Cerebral Artery Occlusion Accompanied by Adult-Onset Still's Disease

Adult-onset Still's disease (AOSD) is a rare systemic inflammatory condition of an unknown etiology. Stroke is a rare complication associated with AOSD; most of these are cerebral infarctions due to the occlusion of small blood vessels. Here, we report the first case of mechanical thrombectomy in a patient with cerebral infarction due to a large vessel occlusion associated with AOSD. A 60-year-old man with no underlying disease was diagnosed with AOSD. Sixteen days after admission, he suddenly lost consciousness and was found to have right hemiplegia and aphasia. Head CT showed early signs of ischemic infarction in the left insular cortex, and head CT angiography demonstrated occlusion in a part of the left middle cerebral artery (MCA). Therefore, we decided that mechanical thrombectomy was an indication of revascularization. We performed mechanical thrombectomy using a Trevo NXT 4 × 28 mm (Stryker, Kalamazoo, USA) and obtained reperfusion of the MCA. The results of the cerebral angiography were indicative of an embolic cerebral infarction, and we investigated the source of the embolism including an insertable cardiac monitor (ICM) (Reveal LINQ, Medtronic, Minneapolis, USA). However, no disease other than AOSD that could be a source of embolism was observed. Therefore, AOSD was assumed to be associated with embolisms. AOSD may cause embolic cerebral infarction and may be indicated for mechanical thrombectomy.

Typical evanescent and atypical persistent polymorphic cutaneous rash in an adult Brazilian with Still's disease: a case report and review of the literature

Adult onset Still's disease (AOSD) is a systemic auto-inflammatory condition of unknown etiology, characterized by high fever, an evanescent, salmon-pink maculopapular skin rash, arthralgia or arthritis and leukocytosis. AOSD can also present with atypical cutaneous manifestations, such as persistent pruritic coalescent papules or plaques and linear lesions that have highly distinctive pathological features and are usually associated with severe disease. Herein, we present a 31-year-old Brazilian man with both typical Still's rash and atypical persistent polymorphic cutaneous manifestations associated with severe systemic inflammatory response syndrome. Eosinophils that are consistently lacking in the AOSD-associated skin lesions were evident in the skin biopsy of the persistent atypical cutaneous manifestations and were either drug-related or AOSD-associated.

Severe inflammatory response and vasculitis leading to quadruple limb amputations

A systemic inflammatory response causing multi-organ failure and requiring multiple amputations was refractory to all treatments except Anakinra, and the cause remains unclear.

Complex Situations in Patients with Adult-Onset Still’s Disease

Adult-onset Still’s disease (AOSD) is a rare systemic inflammatory disorder of unknown etiology, characterized by quotidian or double quotidian fever, a peri-febrile cutaneous eruption, polyarthritis, and multiorgan involvement. AOSD is a challenging disease with protean disease manifestations and rare, albeit potentially life-threatening, complications. In such cases, prompt diagnosis and treatment may prove life-saving.

The purpose of this chapter is to review the diagnosis and management of challenging clinical situations in AOSD patients that are associated with significant morbidity and mortality and to provide the readers with information that could aid their decision-making process.
