[Acute postinfectious glomerulonephritis].

Acute postinfectious glomerulonephritis are defined by an acute nonsuppurative inflammatory insult predominantly glomerular. Its current incidence is uncertain because of the frequency of subclinical forms. The most common infectious agent involved is beta hemolytic streptococcus group A.

[Hamartoma of the spleen (splenoma) in a child with sickle cell anemia].

Hamartomas of the spleen or splenomas are uncommon benign lesions that predominantly occur in adults. We report a case of an 11-year-old girl with sickle cell anemia who had a single splenic 1.8 cm nodule incidentally found during splenectomy and histologically characterized by disorganized red pulp tissue without interspersed white pulp leading to the diagnosis of hamartoma.

Ehlers-Danlos syndrome coexisting with juvenile nephronophtisis.

Ehlers-Danlos syndrome (EDS), a heterogeneous disease of the connective tissues, is diagnosed by a triad of symptoms that include skin hyperextensibility, joint hypermobility and connective tissue fragility. Nephronophtisis (NPH) is an autosomal recessive interstitial nephritis leading to terminal renal insufficiency around puberty. The occurrence of these two rare diseases together is unusual.
