The effect of birth weight on tooth development by Demirjian's method.

OBJECTIVES: The aim of this study was to investigate the impact of birth weight on tooth development in children aged 7-8 years. MATERIALS AND METHODS: This retrospective cohort study comprised 75 children born at Bint Al-Huda Hospital, Bojnurd, in 2013-2014. The children were categorized into three groups based on their birth weight: Normal Birth Weight (NBW), Low Birth Weight (LBW), and Very Low Birth Weight (VLBW). Panoramic radiographs were taken for orthodontic examination, and Demirjian's 8-teeth method was employed to determine dental age. The study compared dental and chronological age within each group. Data analysis utilized SPSS software version 26, employing One-way ANOVA and chi-square tests. Statistical significance was set at P ≤ 0.05. RESULTS: The mean difference in dental and chronological age for Very Low Birth Weight (VLBW) children was 0.22 ± 0.44 years, for Low Birth Weight (LBW) children it was 0.19 ± 0.45 years, and for Normal Birth Weight (NBW) children, it was 0.08 ± 0.46 years. Although the mean difference decreased with increasing birth weight, this trend did not achieve statistical significance (P = 0.55). Furthermore, no significant differences were observed between the weight groups (P = 0.529) or genders (P = 0.191).

Interleukin-6 as A Prognostic Biomarker in Perinatal Asphyxia.

OBJECTIVE: Early diagnosis is has a crucial role in both prevention and treatment of asphyxia-related complications. The current study aimed to evaluate the prognostic value of interleukin-6 (IL-6) and hypoxic-ischemic encephalopathy grade in the prediction of mortality and the developmental status of neonates affected by prenatal asphyxia. MATERIALS & METHODS: This cohort study was conducted on 38 term asphyxiated infants at Ghaem hospital, Mashhad, Iran, from 2013 to 2017. The HIE grade and serum IL-6 levels were determined at the time of birth. The developmental status was evaluated using the Denver II test at the end of the two-year follow-up. RESULTS: HIE grade 3 resulted in 83% mortality rate and developmental delay among all survivors. The mean IL-6 level was 2.7 ng/ml in the control group (not affected HIE), which increased up to 29, 175, and 136 ng/ml in those with HIE grades of 1, 2, and 3, respectively. According to the ROC curve analysis, the cut-off level of 24 pg/ml could predict the developmental delay with sensitivity and specificity of 96 and 92%, respectively. CONCLUSION: The IL-6 level and HIE grade are potential prognostic biomarkers for the determination of mortality and morbidity in asphyxiated neonates.

Evaluation of serum interleukins-6, 8 and 10 levels as diagnostic markers of neonatal infection and possibility of mortality.

OBJECTIVE(S): Bacterial infection contributes substantially to neonatal morbidity and mortality. Early diagnosis of neonatal sepsis is difficult because clinical signs are non-specific. We have evaluated serum IL-6, 8 and 10 as potential early diagnostic markers of neonatal infection and their relationship to mortality rate and poor prognosis. Materials and Methods : A total of 84 infants, aged ≥ 72 hr were enrolled in this prospective case-control trial. The case group (n=41) included babies with clinical and laboratory findings compatible with sepsis and/or positive blood or cerebrospinal fluid cultures. The control group (n=43) included healthy infants. IL-6, 8 and 10 were measured for all infants. Receiver-operating characteristic (ROC) curves were used for the determination of thresholds. Results : Statistically significant differences were observed between control and case groups for serum median level of IL-6, 8 and 10 (P<0.001). IL-6 cut-off values of 10.85 Pg/ml for discriminating between cases and controls and 78.2 Pg/ml for predicting mortality are suggested. IL-8 at a cut-off value of 60.05 Pg/ml was valuable for differentiation of definite versus indefinite infection. Conclusion : Evaluating the IL-6, 8 and 10 simultaneously, could improve the sensitivity and specificity of early diagnosis of the neonatal sepsis. Regarding our results, interleukin 6 had the greatest value for predicting infection and possible mortality, whereas IL-8 was valuable for diagnosing definitive infection.

Effect of prenatal selenium supplementation on cord blood selenium and lipid profile.

BACKGROUND: Selenium is an essential trace element and as a component of selenoproteins it plays a key role as an antioxidant. We aimed to evaluate the effect of selenium supplementation during pregnancy on cord blood selenium content and lipid profile. METHODS: This trial was performed on 166 eligible women who were randomized to receive 100 µg of selenium, as selenium-yeast (Se group) or a placebo-yeast tablet (placebo group). Umbilical cord blood samples were collected at the time of delivery and selenium concentration and lipid profile were measured. RESULTS: Triglyceride levels were found to be significantly higher in the Se group than in the placebo group (p=0.01). However, no significant difference in cord blood selenium was observed between the groups nor were there any significant correlations between cord blood selenium and lipid profile parameters. CONCLUSION: Our findings suggest that selenium supplementation in pregnant women may be associated with an increased cord-blood triglyceride level, although total cholesterol, low-density lipoprotein and high-density lipoprotein cholesterol levels did not change significantly. The clinical significance of the increased cord triglyceride concentration needs to be evaluated.

The Effect of Traditional Remedies (Camel's Thorn, Flixweed and Sugar Water) on Idiopathic Neonatal Jaundice.

OBJECTIVE: Jaundice is the most common reason of newborn's admission to neonatal ward. Many Iranian families give traditional remedies like sugar water, camel's thorn and flixweed extracts to breast-fed babies for reducing jaundice. This study investigated the effect of traditional remedies on idiopathic neonatal jaundice. METHODS: This prospective study has been performed on 336 babies with idiopathic jaundice in a four year period (2005-2009) at Ghaem hospital, Mashhad, Iran. The babies were divided into two groups. In case group (n=234) breast-fed babies received no remedy and in control group (n=102), traditional remedies were given additional to breast milk and the results recorded and compared. FINDINGS: In the present study significant differences were observed between the two groups in age of admission (6.8±3.2 vs 9.2±3.7 day, P<0.001), serum bilirubin values (17.8 vs 21.3 mg/dl, P<0.001) and percent of weight loss (P<0.01). There were no significant differences between the two groups in birth weight, sex, gestational age and duration of hospitalization, age at jaundice remission, hematocrit value and maternal factors (age, gestational order, pregnancy and labor problems)(P>0.05). CONCLUSION: Traditional remedies (camel's thorn, flixweed and sugar water) cause more weight loss and delayed reexamination of newborns leading to increased hyperbilirubinemia. These remedies may raise pseudo confidence in parents, which postpones reexamination and follow up of the newborns.

Intrapulmonary arteriovenous shunt in children with chronic liver disease: clinical features, laboratory data and outcome.

OBJECTIVE: To determine the frequency of hepatopulmonary syndrome in children with chronic liver disease, and its clinical and biochemical associations. METHOD: This study included 53 children with chronic liver disease, who underwent contrast echocardiography with agitated saline and measurement of arterial blood gases. RESULTS: Of the 53 patients studied, 18 had intrapulmonary shunting of blood. This shunting was associated with presence of palpable spleen, cyanosis and dyspnea, but not with abnormalities in the biochemical tests of liver function. At 1-year follow-up, there were 5 deaths among 18 patients with intrapulmonary shunt. In a logistic regression model, PaO 2 < 70 mmHg was found to be a predictor of death (p< 0.05). CONCLUSION: Intrapulmonary shunting is a common and important complication in children with chronic liver disease.
