Variability of the optic nerve sheath diameter on brain computed tomography in Turkish children based on sex and age.

BACKGROUND: Optic nerve sheath diameter (ONSD) measurement is a noninvasive method that can be used for intracranial pressure monitoring. Several studies have investigated normal ONSD values in children, but no general consensus has been reached yet. OBJECTIVES: The aim of our study was to reveal normal ONSD, eyeball transverse diameter (ETD), and ONSD/ETD values on brain computed tomography (CT) in healthy children aged 1 month to 18 years. METHODS: Children admitted to the emergency department with minor head trauma and had normal brain CT were included in the study. The demographic characteristics of the patients (age and sex) were recorded, and the patients were divided into four age groups: 1 month to 2 years, 2 to 4 years, 4 to 10 years, and 10 to 18 years. RESULTS: The images of 332 patients were analyzed. When the median values of all measurement parameters (right and left ONSD, ETD, and ONSD/ETD) were compared between the right and left eyes, no statistically significant differences were found. When the same parameters were compared according to age group, the ONSD and ETD values differed significantly (values of males were found to be higher), but the ONSD proximal/ETD and ONSD middle/ETD values did not differ significantly. CONCLUSION: In our study, normal ONSD, ETD, and ONSD/ETD values were determined according to age and sex in healthy children. As the ONSD/ETD index did not statistically significantly differ according to age and sex, diagnostic studies for traumatic brain injuries can be performed using the index.

Use of the pleth variability index in children with obstructive respiratory disease.

INTRODUCTION: The phenomenon of pulsus paradoxus (PP) develops at varying rates in relation to the severity of the disease in obstructive respiratory tract disease. The Pleth Variability Index (PVI) is the measurement value of perfusion index changes that occur with ventilation, which are determined during at least one respiratory cycle. Therefore, noninvasive measurement of PVI can help in the measurement of PP. The current study aims to determine the role of PVI measurements before and after bronchodilator therapy during admission to the hospital in children with obstructive respiratory tract disease. METHODS: Age, gender, Pulmonary Index Score (PIS), and PVI data of patients aged 2-18 years who applied to the pediatric emergency department with signs of obstructive respiratory tract disease were recorded in triage. The PVI and PIS scores of the patients, who were divided into three groups according to their clinical severity scores, were recorded before and after bronchodilator treatment, and they were compared to the PVI values according to the disposition results. RESULTS: A total of 133 patients were included in this prospective, single-center study. The PVI values before and after treatment were significantly higher in patients with severe disease compared to the mild and moderate groups (p < 0.001). Post-treatment PVI values were significantly lower than pre-treatment values in all clinical severity groups (p < 0.001). While a total of 95 (71.43%) patients were discharged from the emergency department, 31 (23.31%) patients were admitted to the relevant department, and seven (5.26%) patients were admitted to the pediatric intensive care unit. The PVI values before and after treatment were significantly higher in the hospitalized group compared to the group discharged from the emergency department (p < 0.001). The areas under the ROCs were 0.940, 0.865, and 0.843 for the PVI measurements in patients with severe disease, moderate disease, and hospitalization (p< 0.001). CONCLUSIONS: Automated PVI measurement can be used as a noninvasive, rapid, and objective tool in the emergency department triage of patients admitted to the pediatric emergency department with signs of asthma attack or reactive respiratory tract disease.

Clinical and laboratory characteristics of children with SARS-CoV-2 infection.

We describe the demographic, clinical, radiological, and laboratory findings of 422 children (0-18 year-of-age) suspected of having severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection admitted to a pediatric emergency department between March 23, and July 23, 2020. We compared the characteristics of SARS-CoV-2-positive patients to SARS-CoV-2-negative patients. SARS-CoV-2 infection was confirmed in 78 (18.4%). Fever (51.2%) and cough (43.5%) were the most commonly reported signs in the SARS-CoV-2-positive patients. Isolated rhinorrhea (7.2%) was reported only in the SARS-CoV-2-negative group (p = .0014). Patients with SARS-CoV-2 infection were classified according to severity, with the percentages of asymptomatic, mild, moderate, severe, and critical cases determined to be 29.5%, 56.4%, 12.9%, 1.2%, and 0%, respectively. Of the 422 children, 128 (30.3%) underwent nasopharyngeal polymerase chain reaction testing for other respiratory viral pathogens; 21 (16.4%) were infected with viral pathogens other than SARS-CoV-2. Only one patient (4.7%) with confirmed coronavirus disease 2019 (COVID-19) disease was coinfected with respiratory syncytial virus and rhinovirus. The results indicate lower median white blood cell, neutrophil, and lymphocyte counts, lower lactate dehydrogenase, d-dimer, and procalcitonin levels in the SARS-CoV-2-positive group (p ≤ .001). Our findings confirm that COVID-19 in children has a mild presentation. In our cohort, no patient with SARS-CoV-2 infection had isolated rhinorrhea.

A rare cause of dyspnea in emergency medicine: transfusion-related acute lung injury.

The earliest definition of transfusion-related acute lung injury (TRALI) included all patients who developed acute respiratory distress, moderate to severe hypoxemia, rapid onset of pulmonary edema, mild to moderate hypotension, and fever within 6 hours of receiving a plasma containing blood transfusion. The definition excluded patients if they had underlying cardiac or respiratory disease. The mechanism is not known exactly but it causes morbidity and mortality. Incidence of TRALI changes between 0.08% and 15% of patients receiving a blood transfusion. A 78 year old female patient with history of myelodysplastic syndrome, coronary artey disease and hypertansion, was admitted to the hospital because of dyspnea after the blood transfusion. She was managed as TRALI after diagnostic workup and transported to the intensive care unit. In the following days her clinical status changed dramatically with complete recovery.
