RESUMO
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). BPD is now understood as a longitudinal disease process influenced by the intrauterine environment during gestation and modulated by gene-environment interactions throughout the neonatal and early childhood periods. Despite of this concept, there remains a paucity of multidisciplinary team-based approaches dedicated to the comprehensive study of this complex disease. METHODS: The Discovery BPD (D-BPD) Program involves a cohort of infants < 1,250 g at birth prospectively followed until 6 years of age. The program integrates analysis of detailed clinical data by machine learning, genetic susceptibility and molecular translation studies. DISCUSSION: The current gap in understanding BPD as a complex multi-trait spectrum of different disease endotypes will be addressed by a bedside-to-bench and bench-to-bedside approach in the D-BPD program. The D-BPD will provide enhanced understanding of mechanisms, evolution and consequences of lung diseases in preterm infants. The D-BPD program represents a unique opportunity to combine the expertise of biologists, neonatologists, pulmonologists, geneticists and biostatisticians to examine the disease process from multiple perspectives with a singular goal of improving outcomes of premature infants. TRIAL REGISTRATION: Does not apply for this study.

El albinismo oculocutáneo (AOC) comprende un grupo de trastornos de herencia autosómica recesiva, producidos por una alteración en la vía sintética de la melanina en la piel, el peloy los ojos. Clínicamente se caracteriza por lahipopigmentación cutánea, ocular y pilar, asociada a alteraciones oculares, como fotofobia severa, disminución de la agudeza visualynistagmo. El AOC tipo 1es producido por mutaciones en latirosinasa, enzima codificada por el genTYR (11q14-q21), habiéndose identificado más de 270 mutacioneshasta la fecha. Presentamos el caso de mellizasnacidas pretérmino, de 14 meses de vida, producto de un embarazo controlado, con AOC. Destacamos la escasa frecuencia de presentación de esta patología en pacientes mellizos.
Oculocutaneous albinism (OCA) is an autosomal recessive disorder caused by a defective synthesis of melanin in the skin, hair and eyes. It is clinically characterized by a generalized reduction of pigment in the skin, eyes and hair, associated with ocular alterations, as severe photosensitivity, reduced vision and nystagmus.The OCA type 1 is caused by mutations in the tyrosinase, enzyme that is codified by TYR (11q14-q21), with more than 270 mutations identified up to date. We report the case of preterm 14 month-olddizygotic females twinsfrom a controlled pregnancy, with OCA. We emphasize the low frequency of presentation of this disease in dizygotic twins.
