AIM To investigate the trueness and uncertainty of two transcutaneous bilirubinometers BiliCheck and Minolta JM-103 in preterm infants; establish cut-off values for the transcutaneous bilirubin (TcB) level, indicating the need for total serum bilirubin (TsB) measurement; and estimate how many blood samples could be saved. METHODS In 133 neonates with(More)
BACKGROUND Although results from blood gas analyzers are frequently used in clinical work surprisingly few and small studies have examined reference intervals for arterial blood gases and acid-base status. We have established reference values based on a large group of healthy people with a wide age distribution. METHODS A group of medical students (n=182)(More)
BACKGROUND Blue light with peak emission around 460 nm is the preferred treatment of neonatal hyperbilirubinemia. However, studies using fluorescent light tubes have suggested that turquoise light with peak emission at 490 nm may be more efficient. At present, the predominant light source for phototherapy is light emitting diodes (LEDs). Hence, the aim of(More)
BACKGROUND Phototherapy using blue light is the treatment of choice worldwide for neonatal hyperbilirubinemia. However, treatment with turquoise light may be a desirable alternative. Therefore, the aim of this randomized, controlled study was to compare the bilirubin isomer distribution in serum of jaundiced neonates after 24 h of therapy with narrow-band(More)
BACKGROUND A sensitive method to detect intrathecal IgG production is important in diagnosing inflammatory central nervous system (CNS) diseases, including multiple sclerosis (MS). OBJECTIVE To compare cerebrospinal fluid (CSF) electrophoresis with isoelectric focusing (IEF), immunofixation-peroxidase electrophoresis (IFPE) and high-resolution agarose(More)
OBJECTIVE To investigate the prognosis of liver disease in Aagenaes syndrome (lymphoedema cholestasis syndrome 1 (LCS1)), which is an autosomal recessive inherited syndrome consisting of neonatal cholestasis with intermittent cholestatic episodes in childhood into adulthood and development of lymphoedema. Forty Norwegian patients are known to have this(More)
BACKGROUND The clinical significance of myocardial infarction related to treatment with percutaneous coronary intervention (PCI) has been subject of great discussion. This subject has been studied for many years using different definitions of peri-procedural myocardial infarction and different biomarkers, the results have varied greatly depending on methods(More)
Persons with glucose-6-phosphate dehydrogenase (G6PD) deficiency may suffer episodesof acutehemolysis triggeredby infection, drugs, andchemicals [1]. Acute favism after ingestion of fava beans is a special type [2]. Recently, two caseswith clinically manifest methemoglobinemia, a hitherto unrecognized feature, were reported [3, 4]. We saw two similar(More)
Recently it was reported that l~«,25-dihydro\y vitamin O, [1,25iOH)zl),l inhibited cell growth in a cell Une derived from a metastasis from renal cell carcinoma. We have examined samples from 23 primary renal cell carcinomas for I,2S-(<)H)2D, receptor content, and compared it with the concentrations in autologous normal kidney tissue. Nineteen of 23 (83%)(More)
