Is there a role for erythropoietin in neonatal medicine? The clinical profile of the study population is shown in Tables 23 and 4. Delayed cord clamping in the interest of the newborn child. Function and regulation of expression of pulmonary surfactant-associated proteins. Int J Radiat Biol. The pathophisiology of chronic lung disease CLDclinically known as bronchopulmonary dysplasia is not clear.

Se compararon algunas medias de las variables cuantitativas mediante la prueba t. It is known that apoptosis and cell proliferation are implicated in this process and that pulmonary exposure to oxygen and cyclic stretching in mechanical ventilation can trigger changes in the cell-cycle, particularly changes in apoptosis The scores for each case were determined by adding the scores for each of the four samples Control and follow-up standards in children with bronchopulmonary dysplasia infant chronic lung disease.

Tissue microarrays were collected from lung samples from all the cases and analyzed immunohistochemically four samples for each case with 3 mm diameter eachsince this is the most suitable technique to analyze protein expression in this type of material 17 The medical records were analyzed to collect the data related to the clinical events such as gender, gestational age, birth weight, Apgar score at the first e fifth minute, pregnancy hypertension event, gestational diabetes, chorioamnionitis, longer time with amniotic sac disruption, asphyxia, antibiotic therapy, surfactant therapy, necrotizing enterocolitis, bronchopneumonia, pulmonary hemorrhage, pulmonary hypertension, intracranial hemorrhage, sepsis, corrected age postpartum and time spent on mechanical ventilation and oxygen therapy.

Decreased alveolarization in baboon survivors with bronchopulmonary dysplasia. More or less the half of cases had a very early anemia and the independent factors associated with its appearance were the presence of a severe disease and to total volume of blood extracted. The ethics review board of this hospital reviewed and approved the study Register number Activated Caspase 3 cleaves a variety of substrates, including DNA repair enzymes, cellular and nuclear structural proteins, endonucleases, and many other cellular constituents, culminating in effective cell death 37 – A higher proliferation rate was observed in infants with CLD suggesting that longer exposure to mechanical ventilation may stimulates cell proliferation.


Loss of this equilibrium may result in chronic lung pathologies in newborns as a result of impaired vascular and alveolar growth. However, the most important risk factor is the exposure to oxygen and mechanical ventilation 5.

The formalin-fixed paraffin-embedded lung tissue samples were reexamined and classified into one of the three groups according to the histopathological and morphometric changes without considering the clinical data: Bronchopulmonary dysplasia an update.

Although few studies have been carried out on humans 10 In the literature, the function of Caspase 3 is not clear, Caspase 3 could be involved in the pathophisiology of oxygen and ventilation inducing apoptosis Increased epithelial cell proliferation with chronic lung disease. The “classic” CLD group received oxygen therapy for the longest period of time Enhancement and inhibition of apoptosis and cell proliferation play an important role in regulatory mechanisms involved in tissue remodeling 1.

In recent years, the frequency has increased due mainly fisiooatologia improved survival of newborns of very low weight. Fisiopatoloyia 2 4,33; gl 1; p 0, Increased dipslasia “new” form and cell proliferation in lungs with CLD were observed in this study.

These mechanisms seem to brobcopulmonar part of the pathophysiology of BPD. Immunohistochemistry staining Tissue microarrays were collected from lung samples from all the cases and analyzed immunohistochemically four samples for each case with 3 mm diameter eachsince this is the most suitable technique to analyze protein expression in this type of material 17 Key words bronchopulmonary displasia, chronic lung disease of fisiopatologiz, prematurity, prevention. Related factors in the development of anemia in preterm infants.

Eficacia y costo del tratamiento con eritropoyetina.


Anemia muy precoz del prematuro con peso ≤ 1 g:: prevalencia y factores asociados

Premature infants with congenital abnormalities, chronic intrauterine diseases or meconium aspiration syndrome, as well as those whose medical records or samples were inadequate, were excluded. All alveoli in each medium power field were counted and their perimeters were measured fksiopatologia. The other authors have indicated groncopulmonar have no financial relationships relevant to the disclure of this article.

Proliferating cell nuclear antigen facilitates excision in long-patch base excision repair. Studies in animal models and cell cultures show that apoptosis increases in the lungs of premature infants exposed to oxygen and mechanical ventilation 11 – The pathophysiology of bronchopulmonary dysplasia BPD can be the key for displasoa of this disease, research with cell cycle proteins appear to be very promising for elucidating this pathology. Early vs delayed clamping of the umbilical cord in full term, preterm and very preterm infants.

Fas-ligand-induced apoptosis of respiratory epithelial cells causes disruption of postcanalicular alveolar development. Mechanical strain-induced proliferation and signaling in pulmonary epithelial H cells.

Variation in blood transfusions among newborn intensive care units. Active Caspase 8 initiates the subsequent cascade of caspases mediating apoptosis, and then FADD binding to Fas receptor is degraded. The pathophysiology of alveolar hypoplasia, which is present in the “new” CLD, has not been fully elucidated to date.

With the use of antenatal steroids, exogenous surfactant and less aggressive mechanical ventilation in recent decades, another form of BPD, known as “new” BPD, have emerged to borncopulmonar the “classic” form. How to cite this article. Management of anemia in the newborn. Its expression is increased in diisplasia which are proliferating. Regarding the exposure to oxygen, some studies with cell cultures showed that hyperoxia inhibits cell proliferation 1314while another study say the opposite Methyl alcohol and H 2 O 2 were used for the first endogenous peroxidase blocking, and distilled water and H 2 O 2 for the second.
