Comparing Budesonide and Fluticasone Propionate in Children with Moderate to Severe Asthma: A Pilot Randomized Controlled Trial

The aim of asthma treatment is to reduce airway inflammation by avoiding environmental triggers and using daily anti-inflammatory medications. This study aimed to compare the effects of fluticasone propionate (FP) and budesonide (Bud) on the clinical symptoms and control of asthma in children with moderate to severe asthma. In this open-label study, children with moderate to severe asthma were randomly selected to receive either FP 250 mcg or Bud 400 mcg for 3 months. Asthma control test scores were measured in both groups monthly. The clinical symptoms, drug adherence, and rescue medication were also evaluated. A total of 50 patients with ages between 4 and 7 years old were included in the study (25 cases received Bud and 25 cases received FP). Asthma control test scores, daily and nocturnal symptoms, and cough rates were significantly improved in both groups. The average asthma control scores for the fluticasone group were 21.68±3.32 in the second month and 24.84±2.67 in the third month, whereas the budesonide group had scores of 18.52±3.32 and 22.48±4.12 during the same periods. These variances were statistically significant. Additionally, the requirement for salbutamol use was notably reduced in the fluticasone group compared to the budesonide group throughout all three months. The efficacy of fluticasone propionate in decreasing the need for rescue medication and enhancing asthma control test scores was markedly superior to that of budesonide.

The relationship between mean platelet volume (MPV) and intraventricular hemorrhage in very low birth weight infants

BACKGROUND

Intra ventricular hemorrhage (IVH) is a major cause of mortality among very low birth weight infants. This study aimed to investigate the relationship between mean platelet volume (MPV) and IVH in very low birth weight infants.

METHOD

In this cohort study, all premature infants weighing less than 1500 grams who were admitted to the NICU were enrolled from August 2018 to July 2019. Brain ultrasonography was performed on the first and seventh days and one month of age and were compared with Platelet count and MPV.

RESULTS

From 183 neonates, 23 cases (12.6%) had IVH. The mean MPV on the first day in the group with IVH was 10.48±0.85 and in the non-IVH group was 9.9±0.74 (P = 0.005). The mean MPV on the seventh day in the IVH and non-IVH group were 10.4±0.92 and 10.03±0.74 (P = 0.04) respectively. On the first and seventh day, for one unit of MPV increase, the chance of IVH increased by 2.68 and 2.1 respectively. (p = 0.001; OR3.643; 95% CI [1.703-7.753]).

CONCLUSION

The mean MPV index is significantly higher in the infants with IVH and therefore it can be used in early detection of IVH in neonates weighing less than 1500 grams.

A randomized clinical trial to assess the effect of zinc and vitamin D supplementation in addition to hypertonic saline on treatment of acute bronchiolitis

Background

Bronchiolitis, the most common cause of hospitalization in infancy has not yet a definitive treatment. This study was conducted to assess the effect of Zinc and vitamin D on treatment of infants with bronchiolitis.

Methods

In this double blind, randomized clinical trial, 94 infants aged 2 to 23 months, admitted in Mousavi Hospital in Zanjan, Iran, with the diagnosis of acute bronchiolitis were randomly assigned into 3 groups. The control group was only treated with hypertonic saline. The two case groups received either 100 unit/kg/day of Vitamin D or 20 mg/day of zinc in addition to hypertonic saline. Wheezing, duration of hospital stay, cough, cyanosis, respiratory distress and the respiratory rate in the first, third and seventh day of hospitalization were evaluated.

Results

There was no significant difference between groups in terms of age, sex, weight, passive smoking, wheezing, oxygen saturation, cyanosis and type of delivery. On the third day of hospitalization, the respiratory rate/min in the control group, the groups receiving vitamin D and zinc were 45.2 ± 10.7, 37.8 ± 3.9 and 41.1 ± 9.1 respectively and the result of repeated measure analysis didn’t show any significant difference between the 3 groups (P = 0.562). Duration of hospitalization in the group receiving Vitamin D or zinc and in controls were 4.2 ± 2.6, 4.4 ± 2.2 and 5.1 ± 2.4 days respectively and this difference was not significant. Zinc receiving patients did not differ from the control group regarding to respiratory rate, cyanosis and wheezing.

Conclusion

Vitamin D or zinc administration was not effective in reducing respiratory rate in children with bronchiolitis.

The effect of symbiotic in the treatment of infantile colic: A double-blind, randomized, placebo-controlled clinical trial

Background

This study aims to evaluate the effect of symbiotic (Pedilact) on the treatment of infantile colic.

Materials and Methods

In this randomized clinical trial in Zanjan, Iran, 76 infants with infantile colic were assigned to two groups of 38 cases using block randomization. The intervention group received 5 drops of Pedilact, a symbiotic containing Lactobacillus reuteri and simethicone (20 mg twice daily), and the control group received placebo in addition to simethicone for 4 weeks. Daily crying time, number of crying attacks per day, and sleep duration were recorded on days 1, 7, 14, 21, and 28, and the results were compared.

Results

Thirty-three infants in the intervention group and 35 infants in the control group were enrolled. There was no significant difference between the two groups in terms of age, gender, gestational age, maternal age, type of delivery, type of feeding, and weight at the beginning and the end of the study (all P > 0.05). Daily crying time in the control and intervention groups decreased from 240 and 210 min/day, respectively, to 0 min/day in both the groups. Daily crying attacks decreased from 5 and 4/day in the control and intervention groups, respectively, to 0/day. Sleep duration in both the groups increased from 720 to 840 and 930 min/day in the control and intervention groups, respectively, but the changes were not significant (P = 0.56, P = 0.52, and P = 0.13, respectively).

Conclusion

We did not find a significant improvement in colic symptoms in infants receiving symbiotic compared to placebo.

The Urinary Uric Acid / Cr ratio as a marker of morbidity and mortality of preterm infants: a case-control study

BACKGROUND

Perinatal asphyxia is one of the main causes of preterm infant mortality. Some studies have shown that The Urinary Uric Acid / Cr (UUA/Cr) ratio may be used as an additional marker for perinatal asphyxia.This study intend to investigate the relationship of this ratio with outcomes of preterm infants admitted to NICU.

METHODS

This case-control study was carried on 102 preterm newborn infants with gestational age of 30 weeks to 33 weeks and 6 days admitted in the neonatal intensive care unit.The case group, consisted of 51 premature neonates with a history of intubation, cardiopulmonary resuscitation, mechanical ventilation and Nasal continuous positive airway pressure (NCPAP) at birth, were compared with 51 matched neonates. The UUA/Cr ratio was measured in the first 24 h after birth. Complications during hospitalization, duration of hospitalization, and final outcome were evaluated.

RESULTS

The mean level of UUA/Cr ratio in case and control group were 5.4 ± 4.1 and 3.6 9 ± 2.9 respectively and this difference was statistically significant (p = 0.014). The UUA/Cr ratio were significantly higher in females, cesarean section delivery, Apgar score ≥ 8, neonates without any complication and neonates with less than 10 days of hospitalization. However, this ratio has no predictive value for the incidence of complications during hospitalization and long-term hospital stay for infants of the case group.

CONCLUSIONS

The Urinary Uric Acid / Cr ratio in the first 24 h after birth in preterm neonates who underwent intubation, NCPAP or cardiopulmonary resuscitation was higher than healthy neonates.

The serum vitamin D levels in children with urinary tract infection: a case-control study

Urinary tract infection (UTI) is one of the most common infections in infants and children. The aim of this study is to evaluate the association between vitamin D levels and urinary tract infections in children. This case-control study was performed on 80 children aged 1–12 years with urinary tract infection referred to the pediatric clinic of Mousavi Hospital in Zanjan, Iran. For each patient in the case group, an individual of the same age and sex was selected in the control group. Vitamin D was measured by the ELISA method. Statistical analysis was performed by SPSS V22 software. In this study, 80 children were divided into two groups of 40 cases (UTI) and control. Serum levels of vitamin D in the case group were significantly lower than in the control group [OR (95%CI) = 3.316 (1.286–8.550),( p = 0.013)]. In females, serum levels of vitamin D in cases were significantly lower than for controls [OR (95%CI) = (5.417 (1.685–17.417), P-value = 0.005)]. No significant relationship was found between serum levels of vitamin D in cases and controls regarding male gender, age and weight. Conclusions: This study showed that vitamin D deficiency has a significant relationship with the prevalence of UTI in children. Vitamin D deficiency and female gender are more frequent risk factors for UTI.

Combination of different clinical reasoning tests in a national exam

INTRODUCTION

Clinical reasoning as a critical and high level of clinical competency should be acquired during medical education, and medical educators should attempt to assess this ability in medical students. Nowadays, there are several ways to evaluate medical students' clinical reasoning ability in different countries worldwide. There are some well-known clinical reasoning tests such as Key Feature (KF), Clinical Reasoning Problem (CRP), Script Concordance Test (SCT), and Comprehensive Integrative Puzzle (CIP). Each of these tests has its advantages and disadvantages. In this study, we evaluated the reliability of combination of clinical reasoning tests SCT, KF, CIP, and CRP in one national exam and the correlation between the subtest scores of these tests together with the total score of the exam.

METHODS

In this cross sectional study, a total number of 339 high ranked medical students from 60 medical schools in Iran participated in a national exam named "Medical Olympiad". The ninth Medical Olympiad was held in Shahid Beheshti University of Medical Sciences, Tehran, Iran, under the direct supervision of the Ministry of Health and Medical Education in summer 2017. The expert group designed a combination of four types of clinical reasoning tests to assess both analytical and non-analytical clinical reasoning. Mean scores of SCT, CRP, KF, and CIP were measured using descriptive statistics. Reliability was calculated for each test and the combination of tests using Cronbach's alpha. Spearman's correlation coefficient was used to evaluate the correlation between the score of each subtest and the total score. SPSS version 21 was used for data analysis and the level of significance was considered <0.05.

RESULTS

The reliability of the combination of tests was 0.815. The reliability of KF was 0.81 and 0.76, 0.80, and 0.92 for SCT, CRP, and CIP, respectively. The mean total score was 169.921±41.54 from 240. All correlations between each clinical reasoning test and total score were significant (P<0.001). The highest correlation (0.887) was seen between CIP score and total score.

CONCLUSION

The study showed that combining different clinical reasoning tests can be a reliable way of measuring this ability.

Comparison of Problem-based Learning With Lecture-based Learning

Background:

Problem-based learning (PBL) is one of the most commonly used educational methods in medical schools of different countries. By working through this method, students think critically, generate ideas, and acquire the knowledge and skills required to become a doctor.

Objectives:

This study aimed to compare problem-based learning with lecture-based learning in the education of medical students.

Materials and Methods:

This crossover interventional study was conducted on 40 medical students in pediatric ward of Zanjan University of Medical Sciences. All of the students were enrolled in the study and divided into two groups by simple randomization. Then two topics in pediatric courses were chosen. One of the topics was presented as LBL for the first group and as PBL for the second group. The other topic was presented as PBL for the first group and as LBL for the second group.

Results:

The median score of the exam was higher in the intervention group compare to the control group for both topics. However, the difference was not statistically significant. Students preferred problem-based learning over lecture-based learning because of motivation boost, a higher quality of education, knowledge retention, class attractiveness, and practical use.

Conclusions:

Students’ knowledge was similar in both methods.
