[Experiences with the preventive use of aminophylline (Euphylline) in apnea and periodic respiration in infants].

Sleep apnea and periodic breathing in infants are the result of a mild hypoxia and they are the requirement for SIDS. As a results of the modern medicine each 4.-5.

[Apneas and periodic breathing in mature newborn infants].

50 healthy term newborn infants without a history of sudden infant death syndrome among their relationship were investigated between the second and fourth day of life using a modified test of Brady and McCann. In a thermoneutral environment pneumograms (respiration by thoracic impendance, heart rate, tcpO2) were obtained with an FiO2 of 21, 16, and 30% oxygen. In 12 of the 50 sleeping infants (24%) apnea periods or periodic breathing were observed with an FiO2 of 16%.

[Recurrent hemolytic-uremic syndrome with positive immunofluorescence].

The hemolytic uremic syndrome is a disease of infancy, its major clinical manifestations include reversible thrombocytopenia, hemolytic anemia, and renal failure. Although a great number of patients with HUS have been published, relapses as well as positive immunofluorescence studies are rare findings. In our patient the disease began at age of 7 years and recovered completely.

[Infantile transitory distal renal tubular acidosis with bicarbonate loss].

Apart from the classic distal renal tubular acidosis (RTA), the proximal RTA, and a few cases of distal RTA and renal bicarbonate wasting we know only 2 cases of infantile transient distal RTA with bicarbonate wasting. A 3 month-old male patient is admitted because of deficient suction, vomiting and dehydration. Despite a strong metabolic acidosis (pH 7,09, bicarbonate 8,6 mMol/l, chloride 110 meq/l) the urine is constantly alkaline; clinically the disease manifests itself in the form of an alkali-resistant RTA.
