Stroke in a child with SARS-CoV-2 infection: A case report.

Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some patients with COVID-19 show widely neurological manifestations including stroke. We report a child who was hospitalized due to seizures and was later diagnosed with COVID-19. Acute infarction was seen in the right putamen, globus pallidus, and the posterior part of the insula. A small focal dilatation within M1 segment of the left middle cerebral artery (MCA) was also observed. According to the present case report, COVID-19 infection may contribute to the occurrence and development of ischemic stroke.

Surveillance of Antibiotic Consumption Point Prevalence Survey 2014: Antimicrobial Prescribing in Pediatrics Wards of 16 Iranian Hospitals.

BACKGROUND: Antibiotics are among the most commonly prescribed drugs in pediatrics. Due to lack of uniformity in pediatric antimicrobial prescribing and the emergence of antibiotic resistance, appropriate drug utilization studies have been found to be crucial to evaluate whether these drugs are properly used. METHODS: Data were collected between January 2014 and February 2014 in 16 Iranian pediatric hospitals using a standardized method. The point prevalence survey included all inpatient beds. RESULTS: Of 858 children, 571 (66.6%) received one or more antimicrobials. The indications were therapeutic in 60.6%. The parenteral route was used in 92.5% of therapeutic indications. Ceftriaxone was the most prescribed antimicrobials for therapeutic indications (32.4%) and combination-therapy was the most type of therapy in pediatric intelligent care unit (PICU). CONCLUSION: According to results of this study, antibiotics' prescribing in pediatrics wards of Iranian hospitals is empirical. Therefore, for quality improvement of antimicrobial use in children continuous audit process and antibiotic prescriptions require further investigation.

Evaluation of procalcitonin and neopterin level in serum of patients with acute bacterial infection.

BACKGROUND: Fever as a common presenting complaint in pediatric patients can be due to various causes. Differentiating bacterial infection from other causes is important because the prompt use of antibiotics is critical in bacterial infection. Traditional markers of infection such as BT and WBC count may be unspecific and culture may be late or absent. CRP and Procalcitonin (PCT) have been considered to evaluate the evolution of infections and sepsis in patients presenting with SIRS. Neopterin has also been proposed to aid in the diagnosis of bacterial infection. In this study, we compared the value of the serum PCT, neopterin level, and WBC count for predicting bacterial infection and outcome in children with fever. METHODS: 158 pediatric (2-120-month-old) patients suspected to have acute bacterial infection, based on clinical judgment in which other causes of SIRS were ruled out were included in the study. WBC count with differential was determined and PCT and neopterin levels were measured. RESULTS: PCT level was higher in bacterial infection and patients who were complicated or expired. CONCLUSION: Rapid PCT test is superior to neopterin and WBC count for anticipating bacterial infection, especially in ED where prompt decision making is critical.

Frequency and antimicrobial susceptibility of Shigella species isolated in Children Medical Center Hospital, Tehran, Iran, 2001-2006.

Appropriate antimicrobial treatment of shigellosis depends on identifying its changing resistance pattern over time. We evaluated 15,255 stool culture submitted from July 2001 to June 2006 to the Laboratory of Children Medical Center Hospital. Specimen culture, bacterial identification, and disk diffusion susceptibility testing were performed according to National Committee for Clinical Laboratory Standards guidelines. From 15,255 stool samples, 682 (4.5%) were positive for Shigella species. The most common species of Shigella were S. flexneri (48%) and S. sonnei (45%); other results were S. dysenteriae (5%) and S. boydii (2%). The rate of sensitivity to ceftriaxone (95%), ceftizoxime (94%), and nalidixic acid (84%) were among our isolates. Resistance to co-trimoxazole and ampicillin was 87% and 86%, respectively. S. flexneri was more multiresistant than other species (47.9%). Our isolates are overall most sensitive to ceftriaxone, ceftazidime, and nalidixic acid (> 84%). They were most resistant to co-trimoxazole and ampicillin (> 86%). Because resistance varies according to specific location, continuous local monitoring of resistance patterns is necessary for the appropriate selection of empirical antimicrobial therapy.
