    Abstract Coronavirus disease (COVID-19) was firstly reported at the end of 2019. The disease rapidly spread all around the world in a few months and was declared a worldwide pandemic by WHO in March 2020. By April 9, there were 1,436,198 confirmed COVID-19 cases in the world, nearly with 6% mortality rate. This novel infectious disease causes respiratory tract illness that may generally occur as mild upper respiratory tract disease or pneumonia. In older patients and/or patients with underlying conditions, it may result in acute respiratory distress syndrome, multi organ failure and even death. According to the current literature, children account approximately for 1%–5% of diagnosed COVID-19 cases. Generally, COVID-19 seems to be a less severe disease for children than adults. Approximately 90% of pediatric patients are diagnosed as asymptomatic, mild, or moderate disease. However, up to 6.7% of cases may be severe. Severe illness is generally seen in patients smaller than 1 year of age and patients who have underlying disesases. The epidemiological and clinical patterns of COVID-19 and treatment approaches in pediatric patients still remain unclear although many pediatric reports are published. This review aims to summarize the current epidemics, clinical presentations, diagnosis, and treatment of COVID-19 in pediatric patients.

    Abstract Rubella infections are rarely seen where immunization programmes are in place. Congenital rubella syndrome is however still observed where the vaccination programme against rubella is not administered or interrupted. We present such a case, with typical clinical anomalies including congenital cataracts, sensorineural hearing loss and bone lesions. The diagnosis was verified by detection of rubella immunoglobulin M positivity in the mother in the first trimester and positive rubella serology in both baby and mother.

    Abstract Introduction: Biologic modifying agents are associated with an increased risk for infection with mycobacteria. The aim of this study is to document patients who received different biologic modifying therapies in our pediatric rheumatology department and the possibility of development of tuberculosis (TB).
    Methodology: This retrospective study was conducted in Ankara City Hospital. Pediatric patients who were treated with biologic modifying agents between 2010-2020 were documented. Development of TB and the risk factors were assessed in this patient group.
    Results: There were 72 patients who were treated with different biologic modifying agents. Tuberculin skin test (TST) was positive in 7 (9.7%) patients during follow up. Three patients whose TST was positive had received canakinumab, 2 received etanercept, 1 received adalimumab and 1 received anakinra. Median duration of therapy was 43.5 (16.5-168) months for these patients and the duration was longer than patients who did not develop latent tuberculosis (p = 0.04). Patients who developed latent TB under treatment were significantly older than the patients who did not (p = 0.01).
    Conclusions: According to our findings, 9.7% of pediatric patients who received biologic modifying agent therapy developed latent TB. Patients who developed latent TB were older, and the duration of treatment was longer than patients who did not develop latent TB. Although not statistically significant, canakinumab, which is known as an agent less likely to cause TST conversion, was in fact the most common agent that caused TST conversion.

    Abstract Human Rhinovirus (HRV) is one of the most common pathogens causing acute respiratory tract infections in infants and children. Several reports suggest that HRV has the potential to cause chronic infection after an acute viral infection in an immunosuppressed patient. Although chronic HRV infection has been reported in lung transplant recipients, patients with hypogammaglobulinemia and cystic fibrosis, the duration and severity of HRV infection remain unclear. In this study, we present a case of persistent HRV infection in a stem cell transplanted leukemia patient. This report raises several questions regarding the risk factors, duration, and severity of persistent HRV infection in acute leukemia patients, which warrants prospective and longitudinal studies.

    Abstract Studies have demonstrated an association between CHD and neurodevelopmental delay. This delay is associated with many factors like reduced blood flow and oxygen, cardiac catheterisations, and genetic factors. Apo E gene polymorphism is one of these genetic factors. This study aims to show the effect of Apo E gene polymorphism on neurodevelopmental process in children having CHD. A total of 188 children having CHD were admitted to the study. Apo E gene polymorphism of these patients was determined, and psychometric evaluation was performed. The relationship between psychometric test results and gene polymorphism was evaluated. This study shows that, similar to the literature, patients having cyanotic CHD have worse scores than acyanotic patients, and the children with CHD are under risk in terms of neuropsychiatric disorders. Other novel and important findings of this study were the lower verbal scores of ε2 allele carriers than ε4 carriers in Wechsler Intelligence Scale for Children-Revised group and the worse test score of patients having VSD than other acyanotic patients. Besides, some special disorders may be seen in this patient group.
