Aim: To demonstrate the demographic data, subgroup distributions, responses to treatment and outcomes of long-term follow-up in patients who were followed up and treated in our clinics with a diagnosis of juvenile idiopathic arthritis, and to compare these data with national and international data. Material and Methods: The files of 116 patients who had been diagnosed as having juvenile idiopathic arthritis, were initiated on treatment and presented for regular follow-up visits between January 2012 and January 2018, were examined. Their demographic findings, treatments, active/inactive disease states (on-medication and off-medication) and treatment response states were evaluated. Results: According to the International League of Associations for Rheumatology criteria, the subtypes were specified as enthesitis-related arthritis (n=38), oligoarticular (n=37), rheumatoid factor (-) polyarticular (n=17), systemic (n=15), rheumatoid factor (+) polyarticular (n=5), and psoriatic juvenile idiopathic arthritis (n=4). In total, the female/male ratio was found to be 1.5. The mean delay time between the first complaint and the diagnosis was found to be 5.7±5.2 months. The patients with systemic type were diagnosed at the earliest, while the patients with polyarticular and enthesitis-related subtypes were diagnosed at the latest. Thirty-two percent of the patients were treated with methotrexate alone, and 38% were given additional biologic drugs. In both treatment groups, the time to achieve inactive disease was the shortest in the oligoarticular group and the longest in the enthesitis-related arthritis group. In the study period, 38 patients were in remission off-medication (the highest rate (53.3%) was observed in the systemic group) and 71 patients were in remission on-medication (the highest rate (70.2%) was observed in the oligoarticular group). Remission was obtained in 94% of the patients. Conclusion: Enthesitis which is the remarkable finding of enthesitis-related arthritis, should not be overlooked in routine physical examination. Awareness of enthesitis can contribute to the prevention of diagnostic delay in children with enthesitis-related arthritis. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the clinical characteristics, risk factors, and prognosis of pertussis in the pediatric intensive care unit. Material and Methods: Patients who were hospitalized in pediatric intensive care unit between January 2017 and January 2019 and diagnosed as having pertussis were retrospectively evaluated. Samples were taken from tracheal aspirate material in intubated patients and nasopharyngeal swabs in the other patients. Samples for Bordetella pertussis were studied using multiplex real-time polymerase chain reaction. Results: Eighteen patients were admitted to our pediatric intensive care unit with a diagnosis of pertussis. Ten patients were female (55.5%), and all patients were unvaccinated. The median age was 40 (range, 38-47.5) days and the median intensive care unit stay was 9 (range, 5-14) days. All patients had respiratory distress, 14 patients had cough (77.7%), four patients had fever (22.2%), and three patients had convulsions (16.6%). Seven patients were intubated. Three patients died of multiple organ failure and cardiogenic shock despite extracorporeal treatment. Respiratory syncytial virus was found in two patients and rhinovirus was found in one patient. The median leukocyte count was significantly higher in non-survivors than in survivors. Blood exchange was performed in three patients due to hyperleukocytosis. Pulmonary hypertension was the most common cardiac pathology detected in echocardiographic examinations. Conclusion: We found that high leukocyte count, viral co-infection, and severe pulmonary hypertension were associated with mortality and morbidity in pertussis. [ABSTRACT FROM AUTHOR]
