RESUMO
We first aimed to investigate resting-state functional connectivity (rs-FC) differences between adolescents exposed to SARS-CoV-2 and healthy controls. Secondly, the moderator effect of PLEs on group differences in rs-FC was examined. Thirdly, brain correlates of inflammation response during acute SARS-CoV-2 infection were investigated. Eighty-two participants aged between 14 and 24 years (SARS-CoV-2 (n = 35), controls (n = 47)) were examined using rs-fMRI. Seed-based rs-FC analysis was performed. The positive subscale of Community Assessment of Psychotic Experiences-42 (CAPE-Pos) was used to measure PLEs. The SARS-CoV-2 group had a lesser rs-FC within sensorimotor network (SMN), central executive network (CEN) and language network (LN), but an increased rs-FC within visual network (VN) compared to controls. No significant differences were detected between the groups regarding CAPE-Pos-score. However, including CAPE-Pos as a covariate, we found increased rs-FC within CEN and SN in SARS-CoV-2 compared to controls. Among the SARS-CoV-2 group, neutrophil/lymphocyte and thrombocyte*neutrophil/lymphocyte ratio was correlated with decreased/increased FC within DMN and SN, and increased FC within CEN. Our results showed rs-FC alterations within the SMN, CEN, LN, and VN among adolescents exposed to SARS-CoV-2. Moreover, changes in rs-FC associated with PLEs existed in these adolescents despite the absence of clinical changes. Furthermore, inflammation response was correlated with alterations in FC within the triple network system.

OBJECTIVE: In this study, it was aimed to evaluate the demographic, clinical and laboratory characteristics of MIS-C patients in our hospital, to share our treatment approach, and to assess the outcomes of short- and long-term follow-up. METHODS: MIS-C patients who were admitted and treated in our hospital between July 2020 and July 2021 were evaluated. Demographic, clinical, laboratory, and follow-up data were collected from patient records retrospectively. RESULTS: A total of 123 patients with MIS-C (median age, 9.6 years) were included the study. Nineteen (15.4%) were mild, 56 (45.6%) were moderate, and 48 (39%) were severe MIS-C. High CRP, ferritin, pro-BNP, troponin, IL-6, and D-dimer values were found in proportion to the severity of the disease (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.005, p < 0.001), respectively. Two (1.6%) patients died. The mean follow-up period was 7.8 months. Valve failure, left ventricular dysfunction/hypertrophy, coronary involvement, and pericardial effusion were the most common cardiac pathologies in the short- and long-term follow-up of the patients. In the long-term follow-up, the most common reasons for admission to the hospital were recurrent abdominal pain (14.2%), cardiac findings (14.2%), pulmonary symptoms (8%), fever (7.1%), neuropsychiatric findings (6.2%) and hypertension (3.5%). Neuropsychiatric abnormalities were observed significantly more common in severe MIS-C patients at follow-up (p = 0.016). In the follow-up, 6.2% of the patients required recurrent hospitalization. CONCLUSION: MIS-C is a serious and life-threatening disease, according to short-term outcomes. In addition to the cardiac findings of patients with MIS-C, long-term outcomes such as neuropsychiatric findings, persistent gastrointestinal symptoms, fever and pulmonary symptoms should be monitored. Key Points ⢠In MIS-C patients, attention should be paid not only to cardiac findings, but also to symptoms related to other systems. ⢠Patients should be followed up in terms of neuropsychiatric findings, persistent gastrointestinal symptoms, fever and pulmonary symptoms that may occur during follow-up.

BACKGROUND: Concerns about the psychiatric sequelae after COVID-19 infection have increased as the pandemic spreads worldwide. The increase in self-isolation during this pandemic period has also revealed the importance of feelings of loneliness. This study aimed to examine the relationship between baseline inflammation levels, internalizing symptoms, and feelings of loneliness in adolescent COVID-19 survivors in the long term. METHODS: A total of 74 adolescents (41 girls, 55.4%, mean age 14.88) and their parents were included in the study. This cross-sectional study assessed internalizing symptoms via Revised Children's Anxiety and Depression Scale (RCADS) and feelings of loneliness using the UCLA-loneliness scale. Baseline inflammatory markers at COVID-19 diagnosis were collected. Logistic regression analysis was used to determine predictors for depression in adolescents. RESULTS: The most common disorder was Major Depressive Disorder (MDD) (25.7%), and 33.8% of the adolescents were in the clinical range in at least one internalizing domain. Baseline C-Reactive Protein (CRP) levels correlated weakly with MDD scores. Loneliness scores correlated with all internalizing symptoms, strong association with MDD scores. Loneliness, anxiety, and parental anxiety were associated with an increased likelihood of MDD. Baseline CRP positivity did not predict MDD in adolescent COVID-19 survivors. CONCLUSIONS: This study indicates that anxiety, loneliness, and parental anxiety play an important role in adolescents' experience of depressive symptoms after COVID-19 infection. Thus, screening parental psychopathology and loneliness in COVID-19 survivors seems to be preventive for adolescent mental health problems.

INTRODUCTION: The aim of this study was to make the differential diagnosis between acute appendicitis and multisystem inflammatory syndrome in children (MIS-C) for patients presenting with the complaint of acute abdominal pain (AAP) and to identify the determining factors for the diagnosis of MIS-C. MATERIALS AND METHODS: Eighty-one children presenting with AAP/suspected AAP were evaluated. Of these, 24 (29.6%) were included in the MIS-C group (MIS-C/g) and 57 were included in the suspected appendicitis group (S-A/g), which consisted of two subgroups: appendicitis group (A/g) and control observation group (CO/g). RESULTS: Comparing MIS-C/g, A/g, and CO/g, duration of abdominal pain (2.4, 1.5, 1.8 days), high-grade fever (38.8, 36.7, 37°C), severe vomiting, and severe diarrhea were higher in MIS-C/g. Lymphocytes count (LC) was lower, while values of C-reactive protein (CRP), ferritin, and coagulopathy were higher in MIS-C/g (p < 0.05). The optimal cutoffs for the duration of abdominal pain was 2.5 days; the duration of fever, 1.5 days; peak value of fever, 39°C; neutrophil count, 13,225 × 1,000 cell/µMoL; LC, 600 × 1,000 cell/µMoL; ferritin, 233 µg/L; and D-dimer, 16.4 mg/L (p < 0.05). The optimal cutoff for CRP was 130 mg/L (sensitivity 88.9, specificity 100%, positive predictive value 100%, NPV, negative predictive value 92.5%, p < 0.001). All patients in MIS-C/g tested positive by serology by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). CONCLUSION: The duration of abdominal pain, presence of high-grade and prolonged fever, and evaluation of hemogram in terms of high neutrophil count and low LC exhibit high sensitivity and negative predictive value for MIS-C presenting with AAP. In case of doubt, inflammatory markers such as CRP, ferritin, D-dimer, and serology for SARS-CoV-2 should be studied to confirm the diagnosis.

Impact of the mandatory Hepatitis A immunization program: before and after the vaccine in Ankara, Central of Turkey. Turk J Pediatr 2019; 61: 677-685. In Turkey Hepatitis A virus (HAV) infection is considered to be moderateendemic. Hepatitis A vaccine was included in the mandatory vaccination schedule of Turkey on November 2012. We aimed to evaluate the cases of HAV infection followed in Ankara, which is located in the center of Central Anatolia, retrospectively according to the date of the administration of the mandatory hepatitis A vaccine. A total of 272 children followed-up between January 2008 and December 2015 for HAV infection in five separate hospitals were enrolled to the study. There were 200 (68.2%) cases in the pre-vaccination group, 72 (31.74%) cases in the post-vaccination group, and 55.1% were male in total. The immunization status were as follow; 89.7% (n = 244) unvaccinated, 0.4% (n = 1) vaccinated and 9.9% (n = 27) with unknown immune status. There was a statistically significant difference between the groups in hospitalization rates, but no statistically significant differences in hospitalization indications, length of hospital stay, complication types and proportions, and normalization period of transaminases. The national hepatitis A immunization program in Turkey has had a significant impact when the targeted population is considered, with suggestive herd protection effects.

This is an observational epidemiological study to describe causes of bacterial meningitis among persons between 1 month and 18 y of age who are hospitalized with suspected bacterial meningitis in 7 Turkish regions. covering 32% of the entire population of Turkey. We present here the results from 2013 and 2014. A clinical case with meningitis was defined according to followings: any sign of meningitis including fever, vomiting, headache, and meningeal irritation in children above one year of age and fever without any documented source, impaired consciousness, prostration and seizures in those < 1 y of age. Single tube multiplex PCR assay was performed for the simultaneous identification of bacterial agents. The specific gene targets were ctrA, bex, and ply for N. meningitidis, Hib, and S. pneumoniae, respectively. PCR positive samples were recorded as laboratory-confirmed acute bacterial meningitis. A total of 665 children were hospitalized for suspected acute meningitis. The annual incidences of acute laboratory-confirmed bacterial meningitis were 0.3 cases / 100,000 population in 2013 and 0.9 cases/100,000 in 2014. Of the 94 diagnosed cases of bacterial meningitis by PCR, 85 (90.4%) were meningococcal and 9 (9.6%) were pneumococcal. Hib was not detected in any of the patients. Among meningococcal meningitis, cases of serogroup Y, A, B and W-135 were 2.4% (n = 2), 3.5% (n = 3), 32.9% (n = 28), and 42.4% (n = 36). No serogroup C was detected among meningococcal cases. Successful vaccination policies for protection from bacterial meningitis are dependent on accurate determination of the etiology of bacterial meningitis. Additionally, the epidemiology of meningococcal disease is dynamic and close monitoring of serogroup distribution is comprehensively needed to assess the benefit of adding meningococcal vaccines to the routine immunization program.

BACKGROUND: The rapid detection of Streptococcus pneumoniae could assist in the management of pneumococcal infections. The Binax NOW S. pneumoniae test is a rapid immunochromatographic test for this purpose. METHODS: Multiplex PCR in parapneumonic pleural effusion fluid (PPEF) and cerebrospinal fluid (CSF) with Binax NOW urinary pneumococcal antigen test (PAT) from 80 children was compared in this study. RESULTS: PAT had a sensitivity of 36.4%, specificity of 97.3%, in CSF. PAT had a sensitivity of 50%, specificity of 81% for parapneumonic pleural effusion fluid. CONCLUSIONS: When rapid management of a serious infection is needed the Binax NOW test could be a reliable method for the exclusion of S. pneumoniae infection.

OBJECTIVE: The aim of this multicenter prospective study was to evaluate the efficacy of a new bioequivalent formulation of oseltamivir for the treatment of influenza A, influenza B, and H1N1 during the 2010-2011 influenza season. METHODS: We compared the symptoms and signs of 300 pediatric patients presenting to three university hospitals with an influenza-like illness between January and March 2011. Nasal swab specimens were collected from all children and tested by reverse-transcription polymerase chain reaction (RT-PCR) for influenza viruses. After randomization, half of the participants were prescribed oseltamivir, while the other half were observed conservatively. Forty patients who were followed-up for influenza prior to the study were also included in the evaluation. RESULTS: Influenza was confirmed by RT-PCR in 129 children, 71 of whom were prescribed oseltamivir. The durations of the symptoms fever, cough, nasal congestion, and rhinorrhea were significantly shorter for patients who were treated with oseltamivir compared with untreated patients (p<0.002 for all symptoms). Early initiation of oseltamivir therapy (within 48 h of the onset of symptoms) was associated with more favorable outcomes and an earlier recovery than in patients for whom treatment was delayed (beyond 48 h). Thirty-seven patients (28.7%) had H1N1, 44 (34.1%) had influenza A, 46 (35.7%) had influenza B, one (0.8%) had H1N1 plus influenza A, and one (0.8%) had influenza A plus influenza B viruses. In the comparison of the duration of symptoms according to the different virus types, a statistically significant difference was only observed in patients with influenza B who had a longer duration of cough (p<0.001), nasal congestion (p<0.001), and rhinorrhea (p<0.001). CONCLUSIONS: Oseltamivir is an effective treatment for the management of seasonal influenza and H1N1, and should be initiated immediately without waiting for laboratory confirmation of diagnosis.

OBJECTIVE: Congenital heart disease is the most common life-threatening anomaly in the neonatal period. Screening for this disease with portable echocardiography is crucial to diagnose in the early period, and it has benefits in saving time and decreasing the cost. Portable echocardiography has advantages of rapid access and lower costs and also has advantage that in intensive care units there is no necessity to move patients. With these advantages, it is aimed to compare the sensitivity of portable echocardiography comparing to standard echocardiography. METHODS: In this study, the portable echocardiography results of the sequentially enrolled newborns hospitalized in the neonatal departments are revised. Portable echocardiography results were verified with standard echocardiography in 83 (43%) female and 111 (57%) male patients. This study was planned as a study on diagnostic accuracy. RESULTS: The gestational periods were between 24 weeks, 3 days and 42 weeks (average 35 weeks±4 weeks 3 days). Birth weights were between 500 and 4850 grams (average 2370±936 grams). The reason that portable echocardiography had been studied was murmur in 113 (58.2%) patients, cyanosis in 47 (24.2%) patients, prenatal anomaly in 12 (6.2%) patients, bradycardia in 12 (6.2%) patients, maternal diabetes in 6 (3.1%) patients and respiratory distress in 4 (2.1%) patients. Out of 194 patients 8 (4.1%) had differences between standard and portable echocardiography. Compared to standard echocardiography, portable echocardiography has the sensitivity values ranged between 99.3-100% and the specificity values ranged between 90.9-100% in diagnosis of specific CHD anomalies. Positive predictive value was between 50-100% whereas negative predictive value was between 97.9-100%. The agreement between results of two tests was determined as very good - kappa 0.886, 95%CI -0.821-0.951, p<0.0001. CONCLUSION: It is demonstrated that portable echocardiography has a high sensitivity especially diagnosing major heart defects, and with advantages of rapid access and lower costs it is estimated that increasing usage of portable echocardiography could be beneficial.
