[Examination of tumor diameter measurement precision by RECIST].

Image evaluation with Response Evaluation Criteria in Solid Tumors (RECIST) evaluates the change in a measurable lesion as determined by ruler or micrometer caliper. However, there is no definition of the conditions thought to influence the precision of measurement. We therefore examined the effects on measurement precision by changing image amplification, WW, WL, and time phase.

Audiological outcome of infants with congenital cytomegalovirus infection in a prospective study.

The aim of this study was to evaluate the audiological outcome of long-term follow-up of infants with asymptomatic congenital cytomegalovirus (CMV) infection as defined by the presence of CMV DNA in neonatal urine. 12599 pregnant women underwent screening for CMV IgG and IgM antibodies between 1996 and 2003. Eighteen infants with congenital CMV infection were identified.

Improvement of vitamin K status of breastfeeding infants with maternal supplement of vitamin K2 (MK40).

The present study is aimed at evaluating the efficacy of maternal vitamin K2 supplementation on the vitamin K status of newborn infants using the measurement of des-gamma-carboxyprothrombin (PIVKA-II [protein induced by vitamin K absence]) and the hepaplastin test (HPT). PIVKA-II and HPT were measured at the 1st month of age in two groups: 31 infants with maternal vitamin K supplementation (15 mg/d Menatetrenone since the 14th day after parturition) (group 1) and 46 without maternal supplementation (group 2). All infants received vitamin K2 syrup twice within the 1st week of life.
