Complement profile in childhood immune thrombocytopenic purpura: a prospective pilot study.

Immune thrombocytopenic purpura (ITP) is a frequent, usually acute hematologic complication of viral diseases in children. Its evolution is usually benign with spontaneous resolution. Some authors have raised the hypothesis of a possible role of the complement system in the pathogenesis of ITP.

The neonatal variant of Bartter syndrome and deafness: preservation of renal function.

Background: A subtype of antenatal Bartter syndrome and sensorineural deafness (BSND) was originally described among families from southern Israel, and its gene (Barttin, OMIM #606412) has recently been identified. A report has suggested that these children develop chronic renal insufficiency during childhood attributable to chronic tubulointerstitial fibrosis and atrophy.

Methods: Data from 13 infants with BSND, who were born during a 20-year period in our institution, were retrospectively analyzed.

Severe dyspnea due to jellyfish envenomation.

During the summer, jellyfish stings are the most common envenomation situations encountered by humans in the marine environment. The more people swim, scuba dive, or snorkel, the more necessary it is to know what should be done immediately, how life can be saved, how to prevent early and late complications, and how to facilitate convalescence in the event of jellyfish envenomation. We describe an atypical case of a 14-year-old boy with severe dyspnea due to upper airway obstruction caused by a jellyfish sting to the face and outline a practical approach to the treatment of jellyfish stings.

Study Design: Retrospective study.

Fabrication and tests of 3He and 2H targets for beam polarization measurement.

3He and 2H targets were fabricated through implantation of 3He and 2H ions in 0.2-0.3 mm thick tantalum and titanium foils.
