The is weight.Methods: cross-sectional comparative carried out by reviewing medical records newborn delivered for one year in 250 newborn. Birth weight categorized into two as (birth <2500 grams), considered cases, normal ≥2500 controls or the reference weight.Results: In our moth...

OBJECTIVE to determine the risk factors for premature birth. METHODS retrospective case-control study of 600 pregnant women assisted in a hospital, with 298 pregnant women in the case group (who gave birth prematurely <37 weeks) and 302 pregnant women who gave birth to a full-term newborn in the control group. Stata software version 12.2 was used. The Chi-square test was used in bivariate ana...

Congenital cystic adenomatoid malformation (CCAM) is an hamartomatous congenital pulmonary airway malformation with incidence ranging between 1:10,000 and 1:35,000 newborns. Currently CCAM is classified into five groups according to clinical and pathological features. The clinical outcome varies depending on the subtype and the extent of involvement. The authors report the case of a premature m...

OBJECTIVES To examine whether exogenous pulmonary surfactants (exPS) substitute for or merely supplement endogenous pulmonary surfactants (enPS) by looking at sequential changes in the surfactant proteins (SP) SP-A and SP-D in alveolar pools. METHODS Fourteen preterm infants with RDS treated with an artificial surfactant were compared to five normal-term infants without RDS who were treated w...

Background: The impact of SARS-CoV-2 infection during pregnancy is currently uncertain, however, maternal respiratory and intestinal symptoms, as well fetal complications such abortion, intrauterine growth restriction premature delivery have been reported. Case Report: A 27-week pregnant lady with a history Bochdalek hernia corrected at birth presented hematemesis, hematochezia, second stage la...

BACKGROUND: Pneumopericardium (PPC) is one of the rarest pulmonary air leak syndromes, but incidence highest in neonatal period. Risk factors include premature infants with respiratory distress (RD) syndrome, receiving active resuscitation, meconium aspiration and aggressive mechanical ventilation. Several cases have also been reported related to COVID-19. CASE PRESENTATION: We report a case fe...

in 17 hospitals, 13123 new births were born during 1989 in tehran. some well-trained personnel observed the events, filling the required questionnaires, interviewing, and collecting necessary information. among them 730 newborns was low birth weight (less than 2500 grams) which was considered as cases. immediately after each case was born, two normal newborn were randomly selected as controls. ...

OBJECTIVE A review of the indications, contraindications, ideal timing, immunogenic efficacy and reactogenicity (adverse events) of active and passive immunization for extremely preterm infants. SOURCES OF DATA Research in classic textbooks on pediatric infectology and in the electronic databases MEDLINE, Lilacs, PubMed and Akwanmed, using the following health sciences descriptors: premature,...

Persistent pulmonary hypertension of the newborn is a disorder with failure to decrease pulmonary vascular resistance after birth. Persistent pulmonary hypertension of the newborn happens in one out of 500 live births with a mortality rate 10-50%. Right after birth the pulmonary vascular resistance decreases drastically within a few minutes when oxygen enters into the fluid-filled alveoli. Fail...

Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of failed circulatory adaptation at birth, seen in about 2/1000 live born infants. While it is mostly seen in term and near-term infants, it can be recognized in some premature infants with respiratory distress or bronchopulmonary dysplasia. Most commonly, PPHN is secondary to delayed or impaired relaxation of the pulmonary v...
