Wandering spleen is a rare condition that occurs when there is an acquired or congenital hypelaxity of the suspensory ligaments of the spleen, resulting in its migration to any abdominal or pelvic position. ⋯ A wandering spleen is most frequently observed in children and young women. This rare diagnosis should be considered facing a recurrent abdominal pain syndrome, a splenomegaly accompanied with pain, or a pelvic lump. A wandering spleen may lead to torsion of the vascular pedicle of the spleen, a chronic volvulus with portal hypertension, or even a splenic infarction. The diagnosis is performed by computed tomography. Wandering spleen is treated surgically, by splenopexy or splenectomy.

Pre-exposure prophlaxis (PrEP) is the use of antiretroviral drugs by uninfected people to prevent human immunodeficiency virus (HIV) infection. PrEP is used by people who are at substantial risk of being exposed to HIV. ⋯ As a result, the difference between the proportion of people on PrEP and the proportion of people who would be very likely to use PrEP if they could access it -otherwise known as the PrEP gap- remains high. Nowadays, studies continue to explore long-term effects of PrEP as well as expand the array of available technologies and regimens.

Infections are a frequent cause of cerebral vasculitis, important to diagnose because a specific treatment may be required. Infection-associated vasculitis can be caused by angiotropic pathogens (varicella zoster virus, syphilis, aspergillus). They can be associated with subarachnoidal meningitis (tuberculosis, pyogenic meningitis, cysticercosis). ⋯ Cerebral vasculitis are severe conditions and their prognosis is directly linked to early recognition and diagnosis. Infectious causes must therefore be systematically considered ahead of cerebral vasculitis, and the appropriate investigations must be determined according to the patient's clinical context. We propose here an update on the infectious causes of cerebral vasculitis, their diagnosis modalities, and therapeutic options.
