Given that European and national legislation in the field of disability is particularly broad and complex, it is often misunderstood not only by persons with disabilities and their families but also by the general public, schools, public authorities, and politicians, in addition to public and private sector employers.

Moreover, persons with disabilities tend to face great difficulties in enforcing their rights. Inclusion starts with knowledge and respect of their most fundamental rights. This is the reason that has motivated the creation of DHEI, which is a new non-profit organization (NPO) that acts in the disability and inclusion field. As a legal support structure in the field of disability, this NPO seeks to make people with disabilities, their families, and healthcare professionals aware of the existing rights via two main axes: training courses in disability law and frontline legal assistance without cost for people with disabilities and their families. By combining both the human and technical aspects of the law, the DHEI actively works in collaboration with various network partners that share extensive expertise in the field of disability.

We report the case of a 17-year-old man presenting with bilateral visual loss, panuveitis, exudative retinal detachments, and diffuse choroidal infiltration. The patient also complained of headaches and ear pain. Based on the fundus image analysis, fluoangiography, indocyanine green angiography, and optical coherence tomography, Vogt-Koyagani-Harada disease was diagnosed. The patient received high-dose methylprednisolone along with azathioprine. He responded well to treatment with progressive visual improvement and subretinal fluid disappearance. One month later, his right eye exhibited a sectorial retinal vasculitis with infero-temporal vein branch occlusion and massive sub-retinal hemorrhages. Coagulation screening as well as HIV and syphilis serology were all negative; whereas QuantiFERON was positive. An 18F-FDG PET/CT revealed hypermetabolic mediastinal lymph nodes, and a biopsy confirmed active tuberculosis (TB) infection. Anti-TB quadritherapy was initiated, resulting in cytochrome P450 enzyme induction and lowered steroid treatment efficacy, with consecutive recurrence of choroidal inflammation.

Diagnosis is an incredibly dynamic and complex process, which is prone to errors. We all make many diagnostic errors and this, in every healthcare setting, but particularly so in the emergency department. However, these errors are preventable. It is thus essential to better understand how and why these errors occur; then, some simple steps must be taken to avoid their repetition. Many of these errors pertain to the clinical reasoning process and are due to cognitive errors, although other system-related factors are likely present in most cases.
