[Dialysis: past, present, future. Between technology and ecology].

Dialysis, hemodialysis or peritoneal dialysis, allows the purification of body waste, the elimination of excess water (ultrafiltration) and the restoration of homeostasis. The treatment is nevertheless cumbersome and burdened with multiple constraints that have changed little over the last 70 years. The ecological balance of hemodialysis is also very heavy.

[When necrosis threatens the kidney patient…].

Calciphylaxis is a rare but devastating condition characterized by a calcifying thrombosing microangiopathy resulting in painful necrotic skin lesions. Risk factors are multiple, the most important being obesity, disorders of phosphocalcic metabolism and acenocoumarol. Largely unknown by the medical community, its pathogenesis is still incompletely elucidated; its diagnosis by skin biopsy remains difficult and increasingly debated because potentially associated with an aggravation of lesions.
