    Notizen: Abstract Objective To evaluate the efficiency of a new device developed to remove obstructions from endotracheal tubes (ETT) in mechanically ventilated patients. Design Open study in mechanically ventilated sedated and paralyzed ICU patients. Setting General ICU and Laboratory of Respiratory Mechanics of the University of Rome “La Sapienza”. Patients 8 consecutive unselected mechanically ventilated, critically ill patients in which a partial obstruction of ETT was suspected on the basis of an increase of the peak inspiratory pressure (〉20%) plus the difficult introduction of a standard suction catheter. Interventions Obstructions to ETT were removed with an experimental “obstruction remover” (OR) Measurements “In vivo” ETT airflow resistance (0.25; 0.5; 0.75; 1l/s) was evaluated before and after use of the OR; the work of breathing necessary to overcome ETT resistance (WOBett) was also evaluated before and after OR use. Results The use of OR significantly reduced in all patients the ETT “in vivo” resistance (From 5.5±2.3 to 2.9±0.5 cmH2O/l/s at 0.25l/s,p〈0.05; from 9±2.4 to 3.8±0.8 cmH2O/l/s at 0.51l/s; from 12.2±3.5 to 5.7±1.2 cmH2O/l/s at 0.75l/s; from 16.9±6 to 9.3±3.8 cmH2O/l/s at 1l/s,p〈0.01 respectively). Also the WOBett was significantly reduced after use of the OR (from 0.66±0.19 to 0.34±0.08 J/l;p〈0.05) Conclusion This experimental device can be safely and successfully used to remove obstructions from the ETT lumen, without suspending mechanical ventilation, reducing the need for rapid ETT substitution in emergency and life-threatening situations.

    Corticosterone methyl oxidase type II deficiency: a cause of failure to thrive and recurrent dehydration in early infancy (1992)
    Springer
    European journal of pediatrics 151 (1992), S. 170-173

    Notizen: Abstract Corticosterone methyl oxidase type II (CMO II) deficiency is an uncommon cause of salt-wasting in infancy. We describe a boy who presented with recurrent dehydration and severe failure to thrive in the first 3 months of life, associated with mild hyponatraemia (serum Na+ 127–132 mEq/l) and hyperkalaemia (serum K+ 5.3–5.9 mEq/l). The diagnosis was suggested by an elevated plasma renin activity (PRA): serum aldosterone ratio, and subsequently confirmed by an elevated serum 18-hydroxycorticosterone: aldosterone ratio. Treatment with 9α-fluorohydroxycortisone normalized growth parameters and PRA levels. CMO II deficiency should be considered in infants with recurrent dehydration and failure to thrive, even when serum sodium and potassium levels are not strikingly abnormal.

    HLA class I residue mismatch and renal graft outcome (2000)
    Springer
    Transplant international 13 (2000), S. S444

    Notizen: Abstract Donor-recipient HLA matching was retrospectively evaluated in 111 cadaveric renal transplants using Takemoto's ten-residue model in which HLA class I antigens are clustered by crossreactive group (CREGs) on the basis of amino acid sequence homology and the sharing of a particular public epitope. The grade and type of HLA residue mismatching were correlated to posttransplant, class I donor-specific antibody production (monitored by flow cytometry crossmatch), rejection occurrence and clinical outcome during the 1st year posttransplant. In 52 patients with 0 mismatchings (MMs) we observed a low incidence of rejection (11.1 %) and antibody production (11.1 %) for 0 CREG MM grade, while 1 MM was enough to increase immune response against graft (rejection 35 %; antibodies 30 %). Moreover, a significant correlation was observed between Q144, E163, Q62 and L82/R82 epitopes and the incidence of acute rejection and antibody production (“immunogenic” residues) in patients grouped for a single residue mismatch.
