Objective: Appendicitis is a common surgical emergency among children. The coronavirus pandemic affected the system of hospitals more than any other field, and great amount of people were concerned about visiting the hospitals for any reason. In this study, it was aimed to evaluate the profile of appendicitis by emphasizing perforated and acute appendicitis in the pandemic period and to compare the rates with previous three years. Material and Methods: Charts of the children who underwent laparoscopic appendectomy due to appendicitis between March 11-September 30 between 2017-2020 were retrospectively analyzed in terms of demographic data, duration of symptoms, duration between hospital admission and surgery, radiologic imaging and perioperative outcomes. Results: This study includes 467 children who underwent laparoscopic appendectomy. There were 97 procedures in 2020, 111 in 2019, 146 in 2018 and 113 in 2017. Multiple comparison tests revealed that age did not show difference; but onset of symptoms in admission (p= 0.004), hospitalization time before surgery (p< 0.001), total hospitalization time (< 0.001) showed statistically significant difference between years. Pairwise comparisons showed that these parameters were increased in 2020 compared to other years. Perforated appendicitis rate was significantly increased in 2020 when compared to previous years. Conclusion: Although there is no direct relation between appendicitis and COVID-19 infection in the current knowledge, perforated appendicitis was found to be increased in children during the COVID pandemic. Reason of the higher rate of perforated appendicitis may be multifactorial; however, the pandemic appears to have a role in increased morbidity in children with appendicitis indirectly due to delay of hospital admissions.

Case Presentation A 2-year-old boy was referred to the Ankara University School of Medicine Children’s Hospital with a history of recurrent respiratory distress and cyanosis since birth. His medical history was significant for premature birth at 31 weeks via cesarean section, as an infant of a diabetic mother. There was no parental consanguinity. He was hospitalized in the neonatal ICU after birth because of respiratory distress. After receiving invasive mechanical ventilation for 4 days, noninvasive mechanical ventilation and oxygen therapy were given gradually. As a result of further investigations, he received a diagnosis of situs inversus totalis and pulmonary hypertension. He was discharged on postnatal day 53 without supplemental oxygen therapy or treatment for pulmonary hypertension. Up to the age of 2 years, the patient had a history of multiple admissions to hospital for respiratory distress, lower respiratory tract infection, and cyanosis as an inpatient and outpatient. After starting to walk, shortness of breath and coughing occurred with effort.

Most IMDs are diagnosed in the neonatal period and have severe neurological findings. Neuroimaging plays an essential role in the diagnosis. We aim to investigate early cranial MRI findings of newborns suspected with IMDs to determine IMD-related neuroimaging patterns in the early infant period.The medical records of a total of 195 infants with suspected IMDs were screened, and 56 patients who underwent a cranial MRI within the first three months of life were included in the study. The 56 patients were categorized into those diagnosed (Group I) and those not diagnosed (Group II) with IMDs. The patient's clinical findings and radiological imaging reports were extracted to a database.The most common IMDs were mitochondrial diseases, urea cycle disorders, and organic acidemias. In the cranial MRI evaluations, the T2-hyperintensity of white matter and the T2-hyperintensity of basal ganglia were higher in Group I. It was found that high lactate/lipid peaks onEarly neuroimaging findings are essential in evaluations of IMDs, so familiarity with neuroimaging findings is essential for diagnosis, especially in countries that lack an expanded neonatal screening program.
