[Primary focal segmental glomerular sclerosis in children: epidemiology and prognosis].

Focal segmental glomerulosclerosis (FSGS) is the morphologic description of a glomerular lesion which is "focal", meaning a few but not all of the total sampled glomeruli have and "segmental" solidification of the tuft that is an accumulation of extracellular matrix with obliteration of the capillary lumina (sclerosis). It represents 20% of nephrotic syndrome in children and adults. To study the role of epidemiology, clinical presentation, histology, and treatment in the prognosis of HSF child, we retrospectively analyzed 23 children with primary focal segmental glomerulosclerosis (FSGS) hospitalized in pediatric nephrology unit of Children's Hospital Harrouchi Abderrahim, CHU Ibn Rochd Casablanca from January 2000 to December 2012.

[Primary peritonitis in children with nephrotic syndrome].

The primitive peritonitis (PP) is one of the rare but severe complications of the nephrotic syndrome. Through a series of 25 children who suffer from a primitive peritonitis complicating or revealing a nephritic syndrome, we tried to analyse the epidemiological and bacteriological aspects of these peritonitis. The mean age of the children is 7 years old with neat male predominance (3 boys/1 girl).

A rare cause of painful cervical swelling: myositis ossificans progressiva in childhood. Report of a case.

Myositis ossificans progressiva (MOP) is a rare condition of which we report a case in a 13-year-old girl with involvement of the cervical paraspinal and periscapular muscles. No ectopic ossifications were visible on plain radiographs. Computed tomography disclosed diffuse inflammation.
