G-6PD "ankara". a new G-6PD variant with deficiency found in a Turkish family.

A new G-6PD varient with enzyme deficiency is described in a 7-month-old Turkish boy without any hemolytic manifestation, except neonatal hyperbilirubinemia. The main characteristics of this variant were the following: Severe enzyme deficiency in erythrocytes (8% of normal), fast starch-gel-electrophoretic mobility (110% of normal), increased Ki NADPH with respect to NADP+, slightly biphasic pH curve, enzyme instability, in vivo and in vitro, decreased molecular specific activity (58% of normal).

[Hemodynamic consequences of umbilical arterial catheterization. Photoplethysmographic study].

The hemodynamic consequences of umbilical arterial infusions in newborns can be registered by photoplethysmography. Thirty-nine children were observed according to the same protocol: it was possible to recognize, on the side of the infusion, without other clinical symptoms, very early but after different times: - in 3 cases, the supression of arteriolar oscillations, back to normal after 24 hours in one case, and after several weeks in 2 cases; - in 2 cases, a transitory increase of arteriolar oscillations; - in 7 cases, an elective decrease of the arteriolar systolic pressure, with unchanged diastolic pressure. In 4/7 cases, it became normal in less than 3 days; - in 3 cases, a decrease in arteriolar systolic and diastolic pressures, during 2 days.
