Autoimmune pancreatitis (AIP) remains little known. It is part of the differential diagnosis of acute non-alcoholic, non-biliary pancreatitis. The clusters of arguments in favor of type 1 AIP diagnosis are the clinical profile (male aged 50-70), the imaging (diffusely enlarged, “sausage-like”, pancreas), the elevation of serum IgG4 beyond the threshold of 135 mg/dl, the histological criteria and the disease corticosensitivity. Type 1 AIP is a component of the systemic IgG4 disease. Lymphadenopathies, pancreatitis and tubulointerstitial nephritis are the most frequent pathologies occurring in IgG4 disease. The evolution is often favorable following treatment with corticosteroids. Given the risk of relapse, a follow-up is necessary. The purpose of this article is to highlight the major elements leading to the diagnosis and treatment of type 1 AIP.

Proton pump inhibitors, an essential treatment of gastric acid-related disorders, can cause hypomagnesemia, associated with functional hypoparathyroidism and hypocalcemia. Symptoms may be either minor like cramps or more severe like rhabdomyolysis, cardiac arrhythmias, or epilepsy. We have herein reported on two cases presenting with severe hypomagnesemia, which quickly resolved following drug withdrawal. We have additionally reviewed the underlying mechanism, which is only partially elucidated to date, though possibly linked to a reduced intestinal absorption of magnesium, which as dependent on the channel TRPM6 (transient receptor potential melastatin type 6).

GIST are rare mesenchymal tumors, and their pre-operative diagnosis may prove challenging. This can be accounted for by less accessible anatomical localizations, and particularly the duodenum and angle of Treitz, in addition to the fact that the biopsies obtained may turn out to be poorly contributory. Surgical intervention that usually allows for a formal diagnosis remains the cornerstone of treatment. When a GIST is suspected, surgery must be encouraged and this, even in the absence of histologically confirmed disease.
