Background Head growth and anterior fontanel (AP) closureare passive processes in response to brain growth. The growthof the brain and skull starts in the third week of intrauterinegestation. roth processes run simultaneously as a part of integralgrowth, along 'With increasing gestational age, until post􀀿birth.Measurement of head circumference (He) and AF in newbornsis done to determine if the brain and skull grew normally duringthe intrauterine period.Objectives To investigate the differences in He and AF sizebetween preterm and full􀀿term infants, and the relationshipbetween gestational age (GA) and birth weight (BW) to Heand AF size.Methods This was a descriptive analytic study on preterm andfull􀀿term newborns. Measurement of HC and AF was conductedin three phases: just after birth, 1x24 and 2x24 hours of age.Analysis of HC and AF size differences between preterm and fullterm subjects was performed, as well as analysis of the correlationbetween GA and BW to HC and AF size.Results Two hundred fifty newborns completed the study. Therewere 180 full􀀿term and 70 preterm subjects. Median HC in full􀀿term and preterm male subjects were 34 cm (range 31􀀿37 cm)and 31 cm (27􀀿34 cm), respectively. Median HC in full􀀿termand preterm female subjects were 33 cm (31􀀿36 cm) and 32 cm(27􀀿3S.S cm), respectively. Median AF in full􀀿term and pretermmale subjects were 2.17 cm (1.0SA.6 cm) and 2.22 cm (1.3SA.Scm), respectively, and in full􀀿term and preterm female subjectswere 2.02 cm (lA.1S cm) and 2.22 cm (0.7SA cm), respectively.The HC of preterms were significantly lower than the fullterms(P<O.OOl), however the AF size was not different between these2 groups of newborns (P =0 .28). Correlation test between GA andBW to HC size revealed a positive correlation (r=0.620, P<O.OO 1and r=0.801, P<O.OOl, respectively), but not to AF size (r=􀀿 0.06,p􀁀 0.279 and F- 0.049, P􀁀0.44, respectively).Concl usions We found that the HC size of pre terms wassignificantly lower than thefullterms, but no significant differences in AF size between the two groups. GA and BW were associatedwith HC size, but not associated to AF size. [paediatr lndones.2012;52:145-51].

The frequency of sex chromatin-positive nuclei during the first 7 days of life was determined in oral mucosa smears stained with lactic acetic orcein in three groups of newborn female infants: 28 cases of full-term newborns, 17 cases of infants with low birth weight (less than 2,000 gm) and high gestational age (more than 32 weeks), and 11 cases of infants with low birth weight and low gestational age (32 weeks or less). A transient suppression of sex chromatin frequency was observed for the first 3 days of life in the full-term females, as has been reported by previous workers. The infants with low birth weight and high gestational age likewise showed transient suppression. The infants with low birth weight and low gestational age, on the other hand, exhibited no comparable suppression of sex chromatin. The findings suggest that the mechanism responsible for sex chromatin suppression is related to a physiologic process that develops in the last 8 weeks of gestation.

Relevance: The growth of neuropsychiatric diseases caused by perinatal pathology indicates the need to study the biochemical markers of brain damage in the newborn for the timely prevention of adverse consequences. Serotonin in early ontogenesis provides intensive development of neuronal structures and cortical networks involved in the mechanisms of formation of cyclic sleep organization a fine criterion of morphofunctional development of the brain. aim: The aim of the work is to study the content of serotonin in healthy full-term newborns in comparison with the quantitative and qualitative characteristics of the electropoligraphic sleep pattern. Material and methods: 84 healthy newborns were examined, which, depending on the gestational age, were divided into 3 groups: I 37 weeks (20 people), II 38 weeks (24 people), III 39-40 weeks (40 people). The content of serotonin in platelet-rich plasma of blood from the umbilical cord vein and in platelet suspension prepared from venous blood taken from mothers and children on the first day of life and again on day 5 was determined by high-performance liquid chromatography with electrochemical detection. A quantitative and qualitative analysis of the sleep electropoligram was performed 7-12 hours after birth. Results: The content of serotonin in platelet-rich plasma in umbilical cord blood in children does not depend on the method of birth, is 2 times lower than in the venous blood of mothers (0.379 0.116 microns/l, versus 0.756 0.200 microns/l, but there is a high correlation between the indicators (r = 0.8, p 0.05). At the gestational age of 39-40 weeks, the level of serotonin in platelet-rich plasma and in venous blood platelets is significantly higher than in those born at 37 weeks. In the latter, the increase in the content of serotonin in platelets continues after birth (at day 1, 0.539 0.149 nM/109 Tr, and on day 5 0.846 0.094 nM/109 Tr; p 0.05), whereas the indicators for those born at 39-40 weeks of pregnancy. They do not change (0.797 0.190 nM/109 Tr and 0.749 0.142 nM/109 Tr, respectively). A significant increase in the content of serotonin in the platelet-rich plasma and in the platelets of the child in the period from 37 to 39 weeks, both during intrauterine development and in the first days of life, correlates with an increase in the representation of the orthodox phase in the sleep cycle. Conclusion: The general pattern of changes in serotonin content and cyclic sleep organization in the early neonatal period in healthy newborns, depending on gestational age, indicates the possibility of using the obtained standard values of serotonin as a biochemical marker of functional brain development.

Purpose. To perform fundus examinations of full-term and premature infants to identify common congenital ocular diseases and determine the incidence and additional risk factors in Ningbo, China. Methods. Fundus examinations were performed on newborns between January 2017 and July 2020 in Ningbo using a RetCam3 or PanoCam LT wide-field digital imaging system. The neonates’ birth weight, gestational age, gender, delivery mode, oxygen intake, and other conditions were recorded. We compared the incidence of ocular abnormalities in both full-term newborns and premature infants. Results. There were 23,861 newborns in this study comprising 12,605 (52.8%) male and 11,256 (47.2%) female infants, 20,938 full-term babies, and 2,923 premature babies. The average gestational age was 37.9 ± 5.6 weeks, and the average birth weight was 3,189 ± 417 g. Overall, we found ocular abnormalities in 6,645 (27.8%). The most common abnormality in full-term newborns was retinal hemorrhage (RH), which we found in 3,827 (18.3%) cases. Other diseases identified included familial exudative vitreoretinopathy (FEVR), retinoblastoma (RB), and congenital cataracts. The delivery method had a significant impact on the incidence of neonatal RH ( P < 0.001 ). Retinopathy of prematurity (ROP) was observed in 617 newborns accounting for 21.1% of all screened premature infants. Logistic analysis showed that gestational age and birth weight were important risk factors for ROP ( P < 0.001 ). For treatable diseases, such as ROP, FEVR, congenital cataract, glaucoma, and RB, early identification allows for active treatment or referral to a specialized hospital for further treatment. Conclusion. Early examination and prompt treatment of ocular disorders in newborns are important to avoid lifelong visual impairment. Eye examinations should be performed during the neonatal period and at regular follow-up visits.

Nephron number at birth has relevant clinical importance with implications for long-term renal health. In recent years, the podocyte depletion hypothesis has emerged as an important concept in kidney pathology. This study was aimed at verifying whether human podocyte number changes significantly during intrauterine life. To this end, 62 subjects with gestational ages ranging from 20 to 41 wk were examined. Kidney sections were stained with hematoxylin and eosin and digitally scanned at ×400 magnification. Subjects were subdivided into fetuses (gestational age ≤24 wk, n = 5), preterms (gestational age ≥25 and ≤36 wk, n = 39), and full-term newborns (gestational age ≥37 wk, n = 18). The average podocyte number of 1,908 ± 645, 1,394 ± 498, and 1,126 ± 256 was, respectively, observed in fetuses, preterms, and full-term newborns. A significant main effect ( P = 0.0051) of gestational age on podocyte number was observed with a significantly lower number in full-term newborns than in fetuses ( P < 0.01). Intragroup variability was also observed. We speculate that variations in podocyte number could be correlated with factors such as drugs and maternal diet occurring during intrauterine life. In conclusion, this study shows, for the first time, a decreasing trend in podocyte number during gestation.

Cord serum lipid and lipoprotein values were measured in 117 normal full-term newborns, in 42 full-term newborns who had received antepartum phenobarbital therapy and in 19 full-term newborns who had received antepartum betamethasone-phenobarbital-ritodrine therapy. The values were the same in untreated and phenobarbital treated newborns, whereas a marked hypercholesterolemia with an increase primarily in very-low-density lipoprotein/low-density lipoprotein cholesterol was found in betamethasone-phenobarbital-ritodrine-treated newborns, compared with untreated infants. Furthermore, cord serum lipid and lipoprotein values were compared in 15 untreated and 10 betamethasone- phenobarbital-ritodrine-treated premature newborns. Again, hypercholesterolemia was seen in the treated newborns with an increase primarily in high-density lipoprotein cholesterol. No difference was found in the cord serum lipid and lipoprotein levels of 31 untreated and 11 betamethasone-phenobarbital-ritodrine-treated small-for-gestational-age infants. The hypercholesterolemia seen in appropriate-for-gestational-age infants after this triple drug treatment is probably caused by betamethasone. This is a cause of hypercholesterolemia in the newborn that has not been described earlier.
