Aim: To develop a fast bedside test for prediction and early targeted intervention of bronchopulmonary dysplasia (BPD) to improve the outcome.

Methods: In a multicentre study of preterm infants with gestational age 24-31 weeks, clinical data present at birth were combined with spectral data of gastric aspirate samples taken at birth and analysed using artificial intelligence. The study was designed to develop an algorithm to predict development of BPD.

Aim: To develop a fast bedside lung maturity test.

Methods: Gastric aspirates obtained from premature infants contain lamellar bodies, carrying lung surfactant. To estimate lung maturity, we isolated lamellar bodies from fresh gastric aspirates by centrifugation.

Aim: To evaluate the accuracy of our new rapid point-of-care (POC) test for lung maturity. The method as we describe in an accompanying article was developed with the purpose of improving the outcome from respiratory distress syndrome (RDS). The test enables the delivery of surfactant in infants with immature lungs already at birth and ensures that infants with mature lungs are not treated unnecessarily.

This case report presents a newborn boy with hypoglycaemia, anaemia, jaundice and severe coagulopathy during the first day of his life, imitating sepsis and disseminated intravascular coagulation. One week after the birth he was diagnosed with acute liver failure due to gestational alloimmune liver disease (GALD). Despite the fact that GALD is rare, it must be suspected in all unexplained stillborn children and infants with severe liver disease.

Our case story is about a two year-old girl who, despite full vaccination with neonatal hepatitis B immunoglobulin and hepatitis B vaccination and revaccination with hepatitis B vaccine at one, two and 12 months of age, got chronic hepatitis B presumably due to intrauterine mother-to-child transmission. Her mother was known to be HBsAg and HBeAg positive with genotype C and a viral load of one billion IU/ml. It is important that children with HBV infection are detected and seen in a special department.

Aims: To evaluate area bone mineral density (aBMD) and volumetric BMD (vBMD) by dual-energy X-ray absorptiometry, and relations to bone markers and hormones in adolescent women with Turner syndrome (TS).

Methods: Cross-sectional study in TS patients (n = 37, 16.7 ± 3.

Objective: To determine uterine and ovarian size in Turner syndrome (TS) and to compare uterine and ovarian size evaluated by transabdominal ultrasound (US) and magnetic resonance imaging (MRI) in girls with TS and two groups of controls.

Design: A cross-sectional study.

Patients: Forty-one girls with TS (17·0 ± 3·3 years, range 11·2-24·9 years), 50 healthy age-matched controls (16·9 ± 3·2 years, range 12·5-25·0 years) and 107 Tanner-stage-matched controls (15·0 ± 3·2 years, range 10·1-24·2).

This case-report presents a 5-year-old girl with gastrointestinal symptoms, who became increasingly confused over the last day before admission. She was believed to be in septic shock or have meningitis and was treated with normal saline infusion, glucocorticoid and antibiotics intravenously. A few days later she was diagnosed with primary adrenal insufficiency (Morbus Addison), which is a very rare disorder among children.

This study aimed to determine the dimensions of the thoracic aorta and the predictors of aortic dimensions in girls and young women with Turner syndrome (TS). A cross-sectional study was performed at a secondary care center. The study compared 41 TS patients with 50 healthy age-matched control subjects.
