The effect of complete reopening of schools on the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not fully known. In the 2021–2022 academic year, the Ministry of National Education of Türkiye has decided to continue face-to-face education at all levels and in all private and public schools, by following a series of measures. There are no studies on school transmission reported from Türkiye since then. This study aimed to assess the dynamics of coronavirus diseases 2019 (COVID-19) transmission in schools by evaluating the data of the school contact screening outpatient clinic of a tertiary children's hospital. Methods  According to the Ministry of National Education guidelines in Türkiye, all students in a class with two polymerase chain reaction (PCR)–confirmed COVID-19 cases are sent to their homes and have a SARS-CoV-2 PCR test on the fifth day. While the students with negative test results return to school, students who test positive continue to stay at home until the 10th day. The current study retrospectively analyzed the screening results of primary, middle, and high school students who presented at the school contact screening polyclinic during the first semester of the 2021–2022 academic season. Results  There were a total of 11,608 presentations to the school contact screening polyclinic, and 1,107 children tested positive with SARS-CoV-2 PCR (9.5%). The median weekly positivity rate was 9.7% in primary school, 9.4% in middle school, and 5.6% in high school. The weekly positivity rate increased from the 16th week at all school levels; the positivity rates ran in parallel before this time but significantly increased from the 16th week to the half-term break. Conclusion  The curve of the positivity rates in schools was similar to Türkiye's pandemic curve. In this respect, the low SARS-CoV-2 transmission in schools correlated with the low number of cases in the community.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":"18 1","pages":"077 - 082"},"PeriodicalIF":0.3,"publicationDate":"2022-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43339173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we aimed to determine the incidence of hyperglycemia, understanding the underlying risk factors in MIS-C patients. Methods  All MIS-C patients were retrospectively evaluated and compared according to the presence of hyperglycemia and the need of insulin. Inflammatory markers and body mass index Z-scores were also compared. Results  The median age of the patients with hyperglycemia was higher than those without ( p  = 0.001). Disease severity scores of patients with hyperglycemia were higher. Procalcitonin levels of patients with hyperglycemia were higher, while ferritin, CRP, and interleukin-6 levels were not. BMIs of patients with hyperglycemia were higher ( p  = 0.01) but BMI Z-scores were similar ( p  = 0.055). There was a positive correlation between BMIs and CRP (r: 0.31, p  = 0.015). There was a positive correlation between procalcitonin (r: 0.431, p  = 0.001) and CRP (r: 0.279, p  = 0.029) and maximum PG. Conclusion  Hyperglycemia is a common feature of MIS-C patients and is associated with the severity of the inflammation. As a novel finding, high CRP and procalcitonin should be considered as predictive markers for impaired glucose homeostasis in MIS-C patients.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":"18 1","pages":"031 - 037"},"PeriodicalIF":0.3,"publicationDate":"2022-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43796209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oxidative stress index (OSI) value was significantly higher in the study group compared to the control group (p = 0.024).\u0000 Conclusion Our results confirmed that the thiol/disulfide homeostasis was reduced, and disulfide formation, which is rereducible to thiol, was insufficient in children with S-ECC to compensate oxidative stress compared with the control group. Also, thiol levels were inadequate to compensate for oxidative stress, and thiol/disulfide homeostasis was not an independent parameter for S-ECC. Besides, the increases in the TOS level and OSI value show that oxidative stress had significant effects on S-ECC's etiopathogenesis.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48667316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Testing for SARS-CoV-2 infection helped to define the interventions against the spread of the disease. A polymerase chain reaction (PCR) test has been the mainstay of diagnostic testing. Cycle threshold (Ct) is a semiquantitative value that indicates approximately how much viral genetic material was in the sample. The aim of this study was to evaluate the impact of Ct values among children with SARS-CoV-2 infection. Methods  Between May 3, 2020 and August 3, 2020, clinical laboratory input and the data of patients with positive SARS-CoV-2 PCR tests were retrospectively studied. Results  There was no statistical significance between Ct values and the patient's status, symptoms other than fever, or other laboratory findings. However, the Ct value of patients who had symptoms at the time of admission to the hospital was significantly lower. Conclusion  In this study, symptomatic patients had lower Ct than asymptomatic patients that reflected higher viral loads. In evidence-based medicine applications, it might be useful to correlate the clinical history with laboratory test results. Even symptomatic patients with high Ct value coinfections, or an alternative acute infection, should be considered.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":"18 1","pages":"010 - 016"},"PeriodicalIF":0.3,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44051160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we aimed to evaluate parents' attitudes toward vaccinating themselves and their children. We also searched whether information about the multisystem inflammatory syndrome in children (MIS-C), a severe complication of COVID-19, could change parents' decisions on vaccinating their children. Methods  A questionnaire form consisting of sociodemographic features, COVID-19 vaccination practices, and knowledge about MIS-C was applied to parents of children attending Bezmialem Vakıf University Hospital from March through June 2022. Factors affecting vaccine hesitancy were evaluated. Results  Among 383 parents, COVID-19 history was present in 248 (64.8%), and 165 (43.1%) were hesitant to vaccinate themselves. The number of cases where both parents had received at least one dose of COVID-19 vaccine was 256/354 (72.3%). The most common reasons for vaccine hesitancy were vaccines being new in 53/165 (32.1%) and fears of side effects in 95/165 (57.6%). Parents' hesitation toward vaccination of their children with the COVID-19 vaccine was highest for the 0 to 6 age group (78.9%) (73.6% in the 6–12 age group, and 47.3% in the 12–18 age group). In total, 365/383 (95.3%) parents did not have an opinion about MIS-C. After information was given, 62.5% of the 302 participants who opposed vaccinating children under 6 years changed their decision to have their children vaccinated. Conclusion  Although routine childhood vaccinations were performed in 99% of children, more than half of parents were hesitant to vaccinate their children with the COVID-19 vaccine. The majority did not have an opinion about MIS-C. Briefings by pediatricians about complications of COVID-19 will help avoid vaccine hesitancy.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":"18 1","pages":"127 - 131"},"PeriodicalIF":0.3,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42390365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the mortality from CAP has decreased over the last decade, it is still unacceptably high in lower-middle-income countries (LMICs). We aimed to determine the case fatality rate (CFR), and factors associated with treatment failure and outcome, using recommended antimicrobials. Methods  A 5-year retrospective review of severe pediatric pneumonia admissions between August 1st, 2014 and July 31st, 2019 at the University College Hospital, Ibadan, Nigeria was conducted. Relevant clinical information including antibiotics use and outcome was analyzed using descriptive statistics, test of association, and logistic regression. Results  There were 588 children aged 2 to 59 months, male:female ratio was 1.5:1. About two-thirds were aged ≤12 months. The majority were fully immunized for age (87.2%), about 34% were malnourished and 68% were hypoxemic at presentation. Only 71% of children were commenced on the recommended first-line antibiotics following the Pediatric Association of Nigeria (PAN) antibiotic guidelines. Initial antibiotics were changed in 22.3% of the patients. The need to change intravenous (iv) amoxicillin plus iv gentamicin was necessary in 23.80% compared with 18.1% for iv cefuroxime plus iv gentamicin. Severe acute malnutrition (odds ratio [OR]: 2.8 [95% confidence interval [CI]: 1.1–7.3]) and hypoxemia (OR:2.3 [95%CI: 1.0–5.6]) were independently associated with antibiotics change. The CFR was 1.36%. Conclusion  The low CFR suggests a better outcome compared with other previous studies in LMICs. However, the high rate of antibiotics changes (22.3%) was possibly due to failure of first line antibiotics; especially among malnourished and hypoxemic children. Randomized controlled trial of iv cefuroxime plus gentamicin versus iv amoxicillin plus gentamicin is recommended.","PeriodicalId":16739,"journal":{"name":"Journal of Pediatric infectious diseases","volume":"18 1","pages":"153 - 162"},"PeriodicalIF":0.3,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49358592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to highlight the contribution of vitamin D status to the disease severity of hospitalized pediatric patients suffering from COVID-19 infection.\u0000 Methods This was a cross-sectional study that was conducted on 42 children with documented positive polymerase chain reaction for COVID-19 infection. Detailed history taking and thorough clinical examination were done for each recruited patient. Besides the laboratory and radiological assessment done for COVID-19 patients, 25 hydroxy vitamin D levels [25(OH) D] in the serum were estimated using enzyme linked immunosorbent assay.\u0000 Results Using the cutoff level of 10 ng/mL, only 40% of the patients were below this level and 60% had their vitamin D level more than or equal to 10 ng/mL. Significantly more patients of the first group needed oxygen support (denoting more severe COVID-19 infection and lung involvement). The older the patients, the more evident was vitamin D deficiency among them, and 25(OH) D values were not correlated to weight for length nor weight categories in the studied series of patients suffering from COVID-19.\u0000 Conclusion Vitamin D deficiency affects the severity of pediatric COVID-19 infection in hospitalized patients. It is prudent to advise vitamin D level assessment in such cases and promptly manage the patients accordingly.
