The antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by thrombosis and/or obstetrical manifestations and the persistent presence, at least 12 weeks apart, of antiphospholipid antibodies (aPL) such as lupus anticoagulant (LA) and/or anticardiolipin antibodies (ACL) and/or anti-β2 glycoprotein I antibodies (aβ2GPI). The finding of patients with clinical profile highly suggestive of APS but who are negative for conventional biological criteria has led to the concept of seronegative APS. ⋯ Although seronegative APS is still controversial, there is increasing recognition of the existence of this subgroup. However, clinical relevance of non conventional aPL need to be confirmed by efforts toward standardizing new biological tools and longitudinal studies involving large cohort of patients.

Review Case Reports
[Third degree atrio-ventricular blockade during a myocarditis occurring under anti-PD1 : Case report and literature review].
Immune Checkpoint Inhibitor (ICI) therapy is now a standard of care in numerous cancers with very promising results. Nevertheless, adverse events, and especially immune-related adverse events (irAEs) not reported during clinical trials, are emerging and can be life-threatening. ⋯ Myocarditis occurring during ICI treatment is a rare but potentially lethal event. Daily serum troponin level seems to predict ICI-related myocarditis but interpretation could be difficult in the context of associated myositis. Echocardiography and cardiac MRI are also useful but can remain negative. Electrocardiogram is a cornerstone of myocarditis diagnosis. In case of cardiac involvement, continuous heart rhythm monitoring should be performed in addition to the administration of high-dose corticosteroids therapy and the cessation of ICI therapy. Add-on treatments should be discussed with a well-trained multidisciplinary team.

Infectious myositis is a rare condition that can be caused by bacteria, viruses, parasites or fungi. Muscle pain or weakness are symptoms shared by all type of myositis. Diagnosis is made on clinical presentation: fever and poor general state is found in bacterial myositis, diffuse muscle pain with flu-like symptoms in viral causes, eosinophilia and a tropical travel history can be related to parasitic etiology, and immunocompromising condition suggests fungal infection. ⋯ The causative organism can be identified on blood cultures, skeletal muscle biopsy, serology or any other pathogen specific test. Treatment depends on the causative organism. Open surgical or imaging-guided drainage is usually necessary in bacterial myositis.

Review Case Reports
[Purtscher-like retinopathy associated with adult onset still disease: Case report and review of the literature].
Putscher-like retinopathy is a retinal disease that is similar to the syndrome initially described in 1910 by Purtscher, but occurring in a non-traumatic context. ⋯ When visual functional signs appear during adult Still's disease, it is necessary to evoke Putscher-like retinopathy, and to ask for an ophthalmological expertise.

Sodium-glucose cotransporter type 2 inhibitors (SGLT2i) are new therapeutic agents that improves the management of type 2 diabetes. Clinical trial results for SGLT2i have shown a reduction in blood glucose levels and a decrease in significant cardiovascular and renal complications related to diabetes. However, rare adverse events such as diabetic ketoacidosis have been reported in these clinical trials and in "real life". These ketoacidosis were atypical because the hyperglycemia was less severe than in traditional acute diabetes, hence the name of "euglycemic" ketoacidosis. We detail a series of local cases associated with the use of SGLT2i in type 2 diabetic patients. ⋯ The increasing use of SGLT2i in individuals with type 2 diabetes is likely to increase the number of ketoacidosis cases. It is essential to recognise this complication and prevent it according to each patient's risk factors.
