Impact of the COVID-19 pandemic and the restrictions on pediatric appendicitis in Turkey: A single-center experience.

BACKGROUND: In this study we investigated how the incidence and course of acute appendicitis (AA) changed in children during the pandemic. METHODS: Children diagnosed with AA during the 1-year pandemic period after the first COVID-19 case in Turkey and the previous 1 year were included in the study. Children were divided into two groups: those hospitalized during the pandemic (group A) and those hospitalized in the year before the pandemic (group B). Furthermore, we compared the findings obtained for COVID-19-positive and COVID-19-negative children in the whole study group and within group A. RESULTS: A significant difference was found between the two groups in terms of gender, the rate of vomiting and the number of days of vomiting. Complicated AA was more frequent in group B than in group A. In addition, the hospital stay was significantly longer, the mean number of days with fever was significantly higher, and mean body temperature was significantly higher in COVID-19-positive patients in the whole study group and within group A. CONCLUSIONS: Contrary to most studies in the literature, in the present study the patients in the pre-pandemic period were admitted to hospital later, and this may have been associated with the higher frequency of complicated AA in these patients. During the pandemic, however, the arrangements and warnings of health authorities might have reduced the anxiety and the hesitancy of families to go to the hospital, and hence this may have been associated with the lower rate of complicated AA in this period.

Neurological symptoms and signs associated with COVID-19 in pediatric patients: a single-center experience.

There is insufficient evidence on SARS-CoV-2 induced neurological effects. Studies on CNS involvement during COVID-19 in children are limited. This study aims to identify and manage the neurological signs and symptoms in COVID-19-infected pediatric patients during follow up and plan future follow-ups. Children diagnosed COVID-19 and hospitalized in the pediatric pandemic services, between March 18, 2020, and June 18, 2021, were included in the study. Children with underlying neurological disease were excluded from the study. Patient data retrieved from hospital files and medical records. Children divided into 2 groups, 1 and 2, based on the presence or absence of neurological findings. A total of 243 children received follow-ups in the pandemic wards, 35 (14.4%) of these patients had neurological findings. Major neurological manifestations were headache (n:17, 7%), seizure (n:4, 1.6%), and anosmia/hyposmia (n:17, 7%). The number of boys (n:13, 37.1%) was smaller than the number of girls (n:22, 62.9%) in Group 1. Group 1 showed higher blood leukocyte, lymphocyte, thrombocyte, AST, LDH, d-dimer values. Anosmia/hyposmia occurred more often in girls, anosmia and headache occurred more often over 9 years of age. Pulmonary and hematologic involvement was more common in children with anosmia and headache. Our study is one of the few studies on neurological involvement in COVID-19 in children. To the best of our knowledge, there is limited data on these subjects in the literature.

Evaluation of vaccination status of health care workers for recommended vaccines and their acceptance of SARS-CoV-2 vaccines.

INTRODUCTION: Health care workers (HCWs) are disproportionately exposed to infectious diseases and play a role in nosocomial transmission, making them a key demographic for vaccination. HCW vaccination rates are not optimal in many countries; hence, compulsory vaccination policies have been implemented in some countries. Although these policies are effective and necessary under certain conditions, resolving HCWs' hesitancies and misconceptions about vaccines is crucial. HCWs have the advantage of direct contact with patients; hence, they can respond to safety concerns, explain the benefits of vaccination, and counter antivaccine campaigns that escalate during pandemics, as has been observed with COVID-19. METHOD: A short survey was carried out in May-June 2020 on the vaccination status of HCWs working with pediatric patients with COVID-19. The survey inquired about their vaccination status (mumps/measles/rubella [MMR], varicella, influenza, and diphtheria/tetanus [dT]) and willingness to receive hypothetical future COVID-19 vaccines. The respondents were grouped according to gender, age, occupation, and region. RESULTS: In total, 4927 HCWs responded to the survey. Most were young, healthy adults. The overall vaccination rates were 57.8% for dT in the past 10 years, 44.5% for MMR, 33.2% for varicella, and 13.5% for influenza. Vaccination rates were the highest among physicians. The majority of HCWs (81%) stated that they would be willing to receive COVID-19 vaccines. CONCLUSION: Although vaccination rates for well-established vaccines were low, a majority of HCWs were willing to receive COVID-19 vaccines when available. Education and administrative trust should be enhanced to increase vaccination rates among HCWs.

Epidemiological, Clinical, and Laboratory Features of Children With COVID-19 in Turkey.

Objectives: The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children. Methods: A retrospective study was conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined. Results: There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (n = 582) and females constituted 49.7% (n = 574). The median age of the confirmed cases was 10.75 years (4.5-14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1-3 years of age (9.3%), 148 were 3-6 years of age (12.8%), 298 were 6-12 years of age (25.8%), 233 were 12-15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (n = 583) for a median of 2 days (IQR: 1-3 days). Fever was median at 38.4°C (38.0-38.7°C). The second most common symptom was cough (n = 543, 46.9%). The other common symptoms were sore throat (n = 143, 12.4%), myalgia (n = 141, 12.2%), dyspnea (n = 118, 10.2%), diarrhea (n = 112, 9.7%), stomachache (n = 71, 6.1%), and nasal discharge (n = 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (p < 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (p = 0.38), but the need for intensive care was higher in patients who had an underlying condition (p < 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma). Conclusions: To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution.

Genotypic characterization of Pseudomonas aeruginosa isolates from Turkish children with cystic fibrosis.

Objective: To identify epidemic and other transmissible Pseudomonas aeruginosa strains, genotypic analyses are required. The aim of this study was to assess the distribution of P. aeruginosa strains within the Turkish pediatric cystic fibrosis (CF) clinic population. Methods: Eighteen patients attending the pediatric CF clinic of Cerrahpasa Medical Faculty were investigated in the study. Throat swab and/or sputum samples were taken from each patient at 3-month intervals. The isolates of patients were analyzed by pulsed-field gel electrophoresis (PFGE). The intra- and interpatient genotypic heterogeneity of isolates was examined to determine the clonal isolates of P. aeruginosa within the cohort. Results: A total of 108 clinical isolates of P. aeruginosa were obtained from 18 patients between May 2013 and May 2014. The pulsotypes of the first patient's isolates could not be obtained by PFGE. From the remaining 17 patients and 101 isolates, 55 distinct pulsotypes were detected. The number of pulsotypes observed in more than one patient (minor clonal strains, cluster strains) was 8 (14.5%), and one of them colonized three patients. However, none of them was detected in more than three patients. These pulsotypes were composed of 20 isolates. In addition, with the PFGE analysis of 81 isolates, we detected 47 (85.6%) pulsotypes, which belonged to only one patient. Over different periods of this study, only 2 (11.8%) patients were colonized with the same pulsotype. Conclusion: Our study indicates that there was considerable genomic diversity among the P. aeruginosa isolates in our clinic. The presence of shared pulsotypes supports cross-transmission between patients.
