The discovery BPD (D-BPD) program: study protocol of a prospective translational multicenter collaborative study to investigate determinants of chronic lung disease in very low birth weight infants.

Background: Premature birth is a growing and serious public health problem affecting more than one of every ten infants worldwide. Bronchopulmonary dysplasia (BPD) is the most common neonatal morbidity associated with prematurity and infants with BPD suffer from increased incidence of respiratory infections, asthma, other forms of chronic lung illness, and death (Day and Ryan, Pediatr Res 81: 210-213, 2017; Isayama et la., JAMA Pediatr 171:271-279, 2017).

[[Effects of local treatment with sodium fluoride mouthrinse on peroxidase and hypothiocyanite saliva levels in adolescent]/].

The present work describes and analyzes the results of a randomized clinical trial on adolescents (age 18.2 +/- 0.6) carried out in order to evaluate the effects of a twice daily mouthrinse application containing xylitol, sorbitol, sacarine, ciclamate, aspartame, chlorhexidine, hexetidine or NaF for 14 days on amylase, peroxidase, thiocyanate, hypothiocyanite, secretory IgA and total proteins in whole saliva.

Calcitriol and calcium carbonate therapy in early chronic renal failure.

The aim of this study was to evaluate the effects of a combined low-dose therapy of calcitriol and calcium carbonate on bone metabolism in the early phases of chronic renal failure. A 30-month study involving 17 patients with ECRF was made: 6 months of observation were followed by 24 months of therapy (calcitriol 0.25 microgram/day plus calcium carbonate 1 g/day).

Low-dose intravenous calcitriol treatment of secondary hyperparathyroidism in hemodialysis patients. Italian Group for the Study of Intravenous Calcitriol.

Intravenous calcitriol is known to directly suppress PTH secretion and release. We evaluated the effect of four months of treatment with low-dose intravenous calcitriol on PTH levels in 83 hemodialysis patients. The criteria for including patients in the study were a serum PTH levels at least four times the normal limit, a serum total calcium less than 10 mg/dl and good control of the serum phosphorus level.
