Childhood-onset systemic lupus erythematosus associated with inborn errors of immunity: One or several conditions?

Childhood-onset systemic lupus erythematosus (cSLE) is a multisystem disease; its severity depends on the organs involved. Monogenic diseases have been described as predisposing to the onset of cSLE. Analytical and immunological tests are used for diagnostic confirmation.

Pylephlebitis in pediatrics: A diagnostic challenge.

Pylephlebitis is defined as suppurative thrombosis of the portal vein as a complication of abdominal infections. In pediatrics, the most frequent etiology is appendicitis, generally of late diagnosis, presenting as sepsis, with a high mortality rate. Imaging methods are necessary for diagnosis; the most common are the Doppler ultrasound and computed tomography angiography.

Brodie abscess in the clavicle: an uncommon presentation.

Osteomyelitis is defined as an inflammation of the bone caused by infection. Acute osteomyelitis is common in pediatrics. A Brodie abscess is a type of subacute osteomyelitis, with a historically low incidence; however, its incidence is currently increasing.

Associations between endothelial dysfunction and clinical and laboratory parameters in children and adolescents with sickle cell anemia.

Background: Hematological changes can drive damage of endothelial cells, which potentially lead to an early endothelial dysfunction in patients with sickle cell anemia (SCA). An association may exist between endothelial dysfunction and several clinical manifestations of SCA. The present study aims to evaluate the links between changes in endothelial function and clinical and laboratory parameters in children and adolescents with SCA.

[Direct effect of nitroxoline in the inhibition of bacterial adherence to urinary catheters].

Nitroxolin or 5-nitro-8-hydroxyquinoline, used in the treatment of acute or recurrent uncomplicated urinary tract infection, has been investigated to demonstrate direct inhibitory effect on Escherichia coli adherence to solid surfaces. First of all, influence of growth medium on bacterial adherence was studied. No relation occurs between growth media enhancing production of adhesins and the ability to adhere to solid surfaces.
