Treatment of ventricular arrhythmias (VAs) commonly involves ablating sites showing electrograms with the earliest activity relative to the VA, but there is no threshold value for prematurity guaranteeing success. Ablation of sites with great prematurity can still result in failure.We hypothesized that isochronal map area (ISCA), derived from isochrones indicating electrogram prematurity, could...

OBJECTIVE To describe retinal detachment with macular holes in infants with retinopathy of prematurity and the methods of surgical repair with their outcomes. METHODS A retrospective review of 4 cases of retinopathy of prematurity and 1 case of retinopathy in a full-term infant that resembled retinopathy of prematurity, in which a macular hole and associated retinal detachment developed and s...

background: recent studies have demonstrated the high prevalence of vitamin d deficiency in the general population. pregnancy and preterm delivery are known as risk factors for vitamin d deficiency. consequently, vitamin d level in women with preterm deliveries might vary from those with term pregnancies. in this study, we aimed to compare vitamin d level in term and preterm infant–mother pairs...

abstract background: preterm labor (delivery after 20 weeks and before 37 weeks of gestation) is the leading cause of prenatal mortality in developed countries. many women who have pre term labor have abnom1ally high plasma levels of a-fetoprotein in early pregnancy. methods: this study was designed to evaluate the ability of this biochemical test and a clinical risk factor scoring system to pr...

BACKGROUND It is unclarified as to whether viral co-detection and human metapneumovirus (HMPV) genotypes relate to clinical manifestations in children with HMPV and lower respiratory tract infection (LRTI), and if the clinical course and risk factors for severe LRTI differ between HMPV and respiratory syncytial virus (RSV). METHODS We prospectively enrolled hospitalized children aged <16 year...

BACKGROUND Caffeine, the most commonly used medication in Neonatal Intensive Care Units, has calciuric and osteoclastogenic effects. METHODS To examine the association between the cumulative dose and duration of therapy of caffeine and osteopenia of prematurity, a retrospective cohort study was conducted including premature infants less than 31 weeks and birth weight less than 1500 g. Osteope...

Excess perinatal morbidity and mortality continue to be major problems in developed and developing nations. Most perinatal deaths occur in infants born weighing less than 2500 g. Large expenditures of time, equipment, and personnel have led to striking reductions in neonatal mortality. However, rates of prematurity have not declined. Exploration of proven causes of prematurity and low birth wei...

447 Dear Editor, We would like to report a pilot study to establish the use of smart phone as a diagnostic tool for detecting severe retinopathy of prematurity (ROP) compared to digital wide‐field photographic images. ROP is fast emerging as an important cause of childhood blindness in India.[1‐3] In spite of recommendations for screening of preterm babies to rule out ROP,[4] there is no eviden...
