Background: Nowadays, though more attention is being paid to oral and dental hygiene all over the world, dental caries and periodontal diseases are increasing daily. We decided to study the effectiveness of natural toothbrush in prevention of dental caries and plaque formation. Methods: This analytic, semi-experimental clinical trial included 390 individuals. Subjects were divided into 3 groups: using natural toothbrush, using artificial toothbrush and using both natural and artificial toothbrush. The plaque index and DMFT was assessed at the beginning of the study until 1 year. ANOVA, Kruskal Wallis, LSD, Paired t-test, chi square, Fisher exact and Mc-Nemar tests were used for data analysis. Results: The plaque index in all three groups showed a mean reduction of 0.71. The mean DMFT in the samples before intervention was 8.38 ± 4.14 and increased to 9.1 ± 4.56. At the end of the study, the lowest plaque index was observed in the group using both the natural and artificial methods. During one year follow-up, the plaque index decreased 1.16, 0.83, and 0.21 degrees in the first, second and third groups. Conclusion: The increase in DMFT in the group that used artificial toothbrush was more than other groups. Thus, use of natural toothbrush leads to a decrease in growth rate of DMFT. Therefore natural toothbrush can be used for the cleaning of teeth and prevention of dental caries
Background: Red blood cells transfusion is a useful practice for preterm infants. Large amount of blood is usually wasted in the infants. Considering that few studies have been carried out on infants, the aim of current study was to investigate the frequency of packed red blood cells transfusion in preterm infants admitted to NICU of Shahid Sadoughi Hospital in Yazd during 2016 Materials and Methods: This retrospective descriptive-analytical study was conducted on infants admitted to Neonatal intensive care unit (NICU) of Shahid Sadoughi Hospital, Yazd, Iran during 2016. Variables including fetal age, sex, birth weight, delivery method, Apgar score, infant status, premature birth complications and transfusion information were extracted from medical records of patients. Results: Current study was conducted on 335 premature infants. Among them, 85 cases were received packed red blood cells transfusion (25.4%). Of the infants receiving packed red blood cells, 59 cases (69.4%) were alive and 26 (30.6%) dead. Distribution of preterm complications in infants including respiratory distress syndrome, sepsis, respiratory failure and Pneumothorax was observed in 66 (77.6%), 19(22.4%), 52(61.2%) and 14 patients (16.5%), respectively. There was significant difference between mean age and mean Apgar score in terms of transfusion (p<0.01). The mean volume of consumed blood was 34.20 ± 27.44 ml. The mean volume of wasted blood was 488.39±355.88 ml. Minimum and Maximum volume of wasted blood was 220 and 1873 ml. Conclusion: According to results of current study, the mean age and mean Apgar score in patients undergoing transfusion was lower than those did not have transfusion. Moreover, total volume of wasted blood was 14.2 times more than consumed blood. Therefore, optimal usage of blood products and the use of smaller blood bags are proposed in order to improve the health of infants in intensive care units and lessen complications of blood transfusion in newborns.
Background & Objective: Low birth weight is considered as one the causes of infant mortality across the world. Accordingly, paying attention to neonatal growth leads to mortality rate decrement and consequently prevents future physical and mental disabilities in this age group. Materials & Methods: This historic (retrospective) cohort study was conducted on 280 one-year-old male and female infants who were divided into two equal groups of low and normal birth weights. Then, the developmental status of the neonates at the corrected age of one year was assessed using the Ages and Stages Questionnaire (ASQ). Data analysis was performed using SPSS 19 via t-test and multiple regression analysis. Results: Of the 280 infants examined, 142 (50.7%) of them were male and 138 (49.3%) were female with the mean weight of 640.9±2696.9 gr, and the mean gestational age of 37.8 ± 2.4 weeks. Moreover, the findings revealed that the gross motor skills and the problem-solving areas had the highest levels of developmental delay in the subjects. In addition, a significant relationship was observed between the developmental delay of the neonates in different areas and the variables of birth weight, birth height, birth rate, duration of hospitalization in neonatal intensive care units (NICUs), and some causes of neonatal hospitalization (P<0.05). Conclusion: According to the results, health policymakers were recommended to pay much more attention to the assessment of the developmental status of low-weight neonates for timely diagnosis and treatment as well as the education of health care providers and parents.
