Although the immunopathogenesis of primary biliary cirrhosis (PBC) remains unknown, familial clustering of patients with PBC suggests an important role for genetic factors. In addition, recent data support the thesis that the mucosal immune response against intraluminal pathogens may be involved with the onset of PBC. Mannose-binding lectin (MBL) is a key(More)
AIM To determine if the diuretic spironolactone cross reacts with 17alpha-hydroxyprogesterone (17OHP) in an enzyme linked immunosorbent assay (ELISA) kit used for the mass screening of congenital adrenal hyperplasia. METHODS Concentrations of 17OHP on a blood filter paper disc were measured using an ELISA kit (kit C-7: ENZAPLATE N-17alpha -OHP-7; Chiron,(More)
BACKGROUND Peripherally inserted central catheters (PICC) are being increasingly used in neonatal practice. Their use is not without technical difficulty. This report describes the use of continuous pressure monitoring to detect catheter occlusion in critically ill neonates. METHODS In-line venous pressure of the PICC line was monitored by pressure(More)
Therapeutic hypothermia is recommended for moderate and severe neonatal encephalopathy, but is being applied to a wider range of neonates than originally envisaged. To examine the clinical use of therapeutic hypothermia, data collected during the first 3 years (2012-2014) of the Baby Cooling Registry of Japan were analysed. Of 485 cooled neonates, 96.5%(More)
Ornithine transcarbamylase (OTC) is one of the enzymes involved in the urea cycle. OTC deficiency, which is caused by impaired synthesis of OTC in the liver, is the most common inherited disease of urea cycle disorders. In this paper, we describe the case of an OTC-deficient Japanese boy wherein an analysis based on high-density single-nucleotide(More)
Matrix metalloproteinase-9 (MMP-9) is detected in lung tissues subjected to ventilator-induced injury and is involved in the process of lung injury. We investigated the immunohistochemical expression of MMP-9 in the bilateral lungs of newborns with congenital diaphragmatic hernia (CDH) during mechanical ventilation and evaluated the degree of damage based(More)
More than 1000 hemoglobin (Hb) variants have been identified. Hb Kirksey, a rare Hb variant involving mutation at codon 94 of α2-globin, is associated with low oxygen affinity. To our knowledge, there is no case report on Hb Kirksey in the literature, and, accordingly, the clinical features of patients with Hb Kirksey are currently unknown. We report here(More)
