The latter is influenced by genetic, racial and nutritional factors varying from one population to another, explaining why a standard cannot be applied to all populations. Research question: should the Caucasian frame of reference be dogmatically applied in our African context? Multicenter studies are therefore necessary;hence the interest of this work, the main objective of which was to describe the anthropometric profile of full-term newborns in the city of Douala. Methodology: We carried out a cross-sectional study with an analytical aim and prospective data collection in the maternity wards of the Douala General Hospital, Laquintinie Hospital, District hospitals of Deido, Nylon and Bonassama over a period of 4 months (January to April 2020). We were interested in any newborn, born alive, vaginally or by cesarean section, seen in the first 24 hours from a full-term single-fetal pregnancy whose mother had given consent. We excluded newborns whose term was unclear and those with congenital malformations or signs of embryo-foetopathy. Data collection was done using structured and pre-tested survey sheets. The study variables were obstetric and anthropometric. Statistical analyzes were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables, the percentages with a significance threshold P value Results: During the study period, 305 full-term newborns were included, divided into 172 boys and 133 girls. The average anthropometric parameters of the full-term newborn in the city of Douala were: average weight: 3305 grams, average height: 49.8 centimeters, average head circumference: 34.6 centimeters, average upper arm circumference: 11.3 centimeters, circumference average thoracic: 32.8 centimeters. The percentile distribution showed a 10th percentile at 2656 grams and a 90th percentile at 3966 grams for weight defining the limits for small-for-gestational-age neonates and macrosomes. Conclusion: The anthropometric data of the full-term newborn in the city of Douala were: an average weight of 3305.4 grams, an average height of 49.8 centimeters, an average head circumference of 34.2 centimeters, an average upper arm circumference of 11.3 centimeters, and an average thoracic circumference of 32.8 centimeters with higher valuesin male newborns.展开更多

METHODS: Totally 816 full-term infants admitted in the neonate intensive unit of Boai Hospital of Zhongshan between 1 May, 2008 and 30 June, 2011 were included in the study. Fundus examination was performed and evaluated individually on them at the age of 48 hours after delivery, 2 weeks and 1 month. Some possible risk factors happening prenatally or during delivery such as pregnant related hypertension, placenta previa, placental abruption etc, as well as some neonatal risk factors such as neonatal asphyxia, hypoxic-ischemic encephalopathy (HIE), low birth weight etc, were recorded and evacuated. Then the effect of the risk factors of full-term infants on retinopathy was studied. RESULTS: The incidence of retinal hemorrhage of full-term infants with prenatal pregnant related hypertension (PRH) of the mother (43.6%) was significantly higher than that of full-term infants without (8.0%). (P<0.001). The incidence of retinal hemorrhage of full-term infants with neonatal asphyxia and /or hypoxic-ischemic encephalopathy (HIE)(29.3%) was significantly higher than that of those without (15.7%), but correlation was not found between the severity of retina hemorrhage and the degree of hypoxic disease. A pale color of optic disc was associated with a low birth weight of full-term infant. Full-term infants with birth weigh-less than 2500g had a significant higher incidence of retinopathy than those with birth weight equal or more than 2500g( P<0.001). CONCLUSION: The main influencing factors which lead to retinopathy of high risk full-term infants are prenatal factors such as PRH, and some neonatal risk factors such as asphyxia, hypoxic-ischemic encephalopathy, and low birth weight.展开更多

This study was to investigate the pathogenesis, clinical characteristics and management strategies of RDS in full-term neonates, with the aim of developing a working protocol for improving the outcome in full-term neonates with RDS. Methods A total of 125 full-term infants with RDS were enrolled in this study. Their clinical and laboratory data were collected for analyzing the characteristics of full-term neonatal RDS. Results （1） The 125 cases included 94 male and 31 female infants, vaginal delivery occurred in 80 cases and cesarean section in 45 cases. （2） The onset time of RDS was （3.11±3.59） hours after birth. （3）The possible reasons included severe perinatal infections in 63 patients, elective cesarean section in 34 cases, severe birth asphyxia in 12 patients, meconium aspiration syndrome in 9 patients, pulmonary hemorrhage in 4 patients and maternal diabetes in 3 patients. （4） Complications included multiple organ system failure （MOSF） in 49 patients, persistent pulmonary hypertension of newborn （PPHN） in 25 patients, acute renal failure in 18 patients, severe hyperkalemia in 25 patients, severe metabolic acidosis in 6 cases, severe myocardial injury in 9 cases, pulmonary hemorrhage in 3 cases, disseminated intravascular coagulation in 14 patients and shock in 12 patients.（5） Four patients died, the mortality was therefore 3.2% with the main cause of septicemia complicating of MOSF, but their prognosis was improved while comprehensive treatment measures including early mechanical ventilation and broad spectrum antibiotics were taken into account. Conclusions RDS is not an uncommon disease in full-term infants and is associated with a higher mortality, its clinical characteristics are very different from premature RDS, and its onset is earlier and is more likely to develop into PPHN and/or MOSE The main cause of death is severe infection complicating of MOSF and most patients require prolonged mechanical ventilation. Comprehensive management strategies will help to improve patient＇s prognosis.展开更多
