Nephrocalcinosis in preterm babies.
OBJECTIVES To determine prospectively the incidence and cause of nephrocalcinosis in preterm infants. STUDY DESIGN Inborn babies of gestation less than 32 weeks or birth weight less than 1500 g were eligible to be entered into a prospective observational study. Two renal ultrasound scans were performed, the first at 1 month postnatal age and the second at term or discharge. Data were collecte...
متن کاملEffect of Expiratory Resistive Loading in Expiratory Muscle Strength Training on Orbicularis Oris Muscle Activity
[Purpose] The purpose of this study was to elucidate the effect of expiratory resistive loading on orbicularis oris muscle activity. [Subjects] Subjects were 23 healthy individuals (11 males, mean age 25.5±4.3 years; 12 females, mean age 25.0±3.0 years). [Methods] Surface electromyography was performed to measure the activity of the orbicularis oris muscle during maximum lip closure and resisti...
متن کاملRefractive errors in preterm babies.
Fifty preterm neonates were followed up at the age of 6 months and 1 year. In addition to developmental assessment, a complete ophthalmological examination was done on both visits. The largest (62%) gestational age group was of 34-36 weeks. At 6 months, none of the infants had normal vision. At 1 year of age, 64% of the babies had normal vision while incidence of myopia and hypermetropia was 16...
متن کاملEffects of expiratory muscle work on muscle sympathetic nerve activity.
We hypothesized that contractions of the expiratory muscles carried out to the point of task failure would cause an increase in muscle sympathetic nerve activity (MSNA). We measured MSNA directly in six healthy men during resisted expiration (60% maximal expiratory pressure) leading to task failure with long [breathing frequency (f(b)) = 15 breaths/min; expiratory time (TE)/total respiratory cy...
متن کاملSodium intake and preterm babies.
How much sodium do preterm babies need and when should sodium supplementation start? Sodium is required to maintain extracellular tonicity and positive sodium balance is a prerequisite of growth. However, for most preterm babies, growth is unlikely during the first days after birth, as overall nutritional intake is limited. The primary aim of nutritional management, during this time, should be ...
