[Management of Gitelman syndrome during pregnancy reporting 12 cases].

Introduction: Gitelman syndrome is a rare hereditary renal tubulopathy, responsable of hypokalemia and hypomagnesaemia-related ionic disorders, which management is poorly codified during pregnancy. We report 12 cases of pregnancies with Gitelman syndrome and we compare our data with those of literature.

Material And Methods: It is a report of 12 pregnancies in 5 patients with Gitelman syndrome between 2002 and 2016.

Renal involvement in Behçet's disease. Case report and review of the literature.

A female patient has suffered from Behçet's disease (BD) for 15 years. During one recurrent episode proteinuria and microscopic hematuria were discovered. Renal biopsy revealed focal segmental glomerulopathy with IgA deposits.

Insufficient dialysis shunts: improved long-term patency rates with close hemodynamic monitoring, repeated percutaneous balloon angioplasty, and stent placement.

Over 54 months, 70 short stenoses of 63 shunts (32 Brescia-Cimino fistulas, 31 grafts) in 59 patients necessitated a first percutaneous transluminal angioplasty (PTA). Restenosis led to 63 redilations in 38 lesions. Nine stents were inserted in seven grafts and two proximal veins in seven patients, the indication being that stenosis had recurred twice in 6 months.

Changes in parathyroid hormone during haemodialysis sessions with two different dialysis membranes: specific adsorption of intact parathyroid hormone.

In patients dialysed with two different membranes (cuprophan and high-flux polysulphone) and using three radioimmunoassays recognizing either intact molecule (iPTH), C terminal (cPTH) or median fragments (mPTH), we compared parathyroid hormone levels at the beginning of and during dialysis. At the beginning of dialysis, cPTH and mPTH levels were always increased but iPTH levels were sometimes within the normal range; during dialysis only iPTH distinctly decreased whichever membrane was used. The behaviour of iPTH cannot be explained by crossing through the membrane because its molecular weight is too high; it cannot be explained by the variation of calcium and phosphate parameters during the session because no correlation exists between the variations in plasma levels of iPTH and the variations in phosphorous and calcium levels.

Iododerma and acute respiratory distress with leucocytoclastic vasculitis following the intravenous injection of contrast medium.

A 72-year-old woman with chronic renal failure requiring haemodialysis developed acute iododerma twice, after receiving iodide contrast dye for radiological procedures. Iododerma was localized to the face, scalp and elbows and was associated with papular purpura of the legs. Histopathology of the skin lesions showed acute necrotizing vasculitis.
