The schedule of administration of canakinumab in cryopyrin associated periodic syndrome is driven by the phenotype severity rather than the age.

Introduction: Interleukin-1 (IL-1) blockade is the treatment of choice of cryopyrin associated periodic syndromes (CAPS). Anti-IL-1 monoclonal antibody (canakinumab) was recently registered. However no clear data are available on the optimal schedule of administration of this drug.

Mycophenolate mofetil treatment in two children with severe polyarteritis nodosa refractory to immunosuppressant drugs.

Polyarteritis nodosa (PAN) is a necrotizing vasculitis of small- and medium-sized arteries with multiorgan involvement, rarely reported in childhood. Despite aggressive treatment with the combination of corticosteroids and cytotoxic agents, the overall prognosis is poor in most patients. We report on two siblings, now 15- and 14-year-old, affected with childhood onset PAN, refractory to multiple therapies, who showed rapid clinical and laboratory improvement when mycophenolate mofetil was introduced.

A new familial case of spondylo-epi-metaphyseal dysplasia with multiple dislocations Hall type (leptodactylic form).

We report a father and son affected by spondylo-epi-metaphyseal dysplasia with multiple dislocations (Hall type), also called leptodactylic form. This family contributes to the delineation of the clinical and radiological phenotype of this rare condition.

Characterization of liver involvement in defects of cholesterol biosynthesis: long-term follow-up and review.

Inborn defects of cholesterol biosynthesis are a group of metabolic disorders presenting with mental retardation and multiple congenital anomalies (MCA/MR syndromes). Functional and structural liver involvement has been reported as a rare (2.5-6%) complication of the Smith-Lemli-Opitz syndrome (SLOS) and it has not been fully characterized.
