Progressive Multifocal Leukoencephalopathy in Children with Primary and Secondary Immune Deficiency.
Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system that is caused by John Cunningham virus (JCV). It occurs almost exclusively in immunosuppressed individuals, for example, patients with AIDS and hematological and lymphoreticular malignancies. In this article, we present a review of the literature and 2 case reports with PML. The first report examines a 15-year-old male (who presented with dedicator of cytokinesis 8 deficiency) who was diagnosed as having PML based on characteristic magnetic resonance imaging (MRI) lesions and a positive PCR for JCV in cerebrospinal fluid. He was transferred for bone marrow transplantation after stabilization with therapy of maraviroc and cidofovir. The second report examines a 6-year-old male who presented with encephalitis and was also diagnosed with AIDS. He was diagnosed with PML and started treatment with cidofovir. His clinical status and MRI findings deteriorated rapidly. In immunosuppressive patients who developed encephalopathy, JCV ought to be considered
The Safety and the Efficacy of First-line Antiretroviral Treatment Regimens in Children: A Single Center Experience in Turkey
Objective: Active antiretroviral therapy refers to the use of a combination of drugs for treating human immune deficiency virus infection with the aim of preventing long-term toxicity
Shear wave elastography of parotid glands in pediatric patients with HIV infection
ObjectivesParotid gland (PG) involvement is common among the patients with HIV infection. Shear wave elastography (SWE) is a noninvasive method used to measure the tissue stiffness of several organs including PG. The aim of this study was to evaluate the tissue stiffness values of PGs of HIV-infected children via SWE and compare the results with the counterparts of healthy subjects.Materials and methodsThis single-center, prospective study included the PG examinations of 23 pediatric HIV patients and 40 healthy children via grayscale ultrasound and SWE. Independent sample T test and Mann-Whitney U test were used in statistical analysis.ResultsStiffness of both PGs was significantly higher in patients' group when compared with control subjects. In addition, when the patients were separated into two groups according to the appearance of PG on grayscale ultrasound as homogeneous and heterogeneous, stiffness values were increased in the patients with homogeneous parenchymal appearance. No significant difference was achieved in terms of median CD4 and CD8 counts, HIV RNA levels or median duration of illnesses.ConclusionsPG examination of HIV-infected children via SWE reveals increased tissue stiffness when compared with healthy subjects. SWE can be used as an ultrasound-assisted noninvasive technique in this manner
Prevalence of Mycoplasma pneumoniae from Symptomatic Pediatric Patients Referred to a Child Outpatient Clinic of a University Hospital
Objective: Lower respiratory tract infections are one of the major causes of morbidity and mortality in children worldwide. Besides, epidemiological data on this subject is very limited. Mycoplasma pneumoniae is an important bacterial agent in community-acquired pneumonia (CAP) and may cause mild, moderate and severe lower respiratory tract infections. Clinical diagnosis is very difficult
EXPERIENCE IN CHILDREN IN THE COVID-19 PANDEMIC OF A TERTIARY CENTER, IN ISTANBUL
Objective: The SARS-CoV-2 virus, which unexpectedly has affected the whole world, continues to infect millions of people and causes the death of hundreds of thousands of people. There has been no consensus on the pediatric age group yet. For this reason, it was aimed to share the pediatric group experience of our center
Evaluation of cases of pediatric extrapulmonary tuberculosis: a single center experience
Aim: Extrapulmonary tuberculosis is observed more frequently and leads to complications with a higher rate in children compared with adults because the risk of lymphohematogen spread is higher. In this study, the clinical, laboratory, and radiologic findings and treatment outcomes were evaluated in pediatric patients who were followed up in our clinic with a diagnosis of extrapulmonary tuberculosis
Correlation of laboratory parameters and Chest CT findings in young adults with COVID-19 and comparison of imaging findings with children*
Purpose: We aimed to compare COVID-19 imaging findings of young adults (19-35 years of age) with those of children (0-18 years) and to correlate imaging findings of young adults with their laboratory tests. Materials and methods: This retrospective study included Real Time-Polymerase Chain Reaction (RT-PCR) confirmed 130 young adults (mean age: 28.39 +/- 4.77; 65 male, 65 female) and 36 children (mean age: 12.41 +/- 4.51; 17 male, 19 female), between March and June 2020. COVID-19 related imaging findings on chest CT were examined in young adults and compared with children by the Mann-Whitney U, and Chi-square or Fisher's exact test. Laboratory examinations of young adults were assessed in terms of correlation with radiological findings by the Spearman's correlation analysis. Results: Bilateral multiple distributions (p = 0.014), subpleural involvement, and pleural thickening (p = 0.004), GGOs with internal consolidations were more frequent in adults (p = 0.009). Infiltrations were significantly larger than 20 mm in young adults (p = 0.011). The rates of feeding vessel sign, vascular enlargement, and halo sign were significantly higher in young adults (p < 0.003). Highly significant positive correlations were found between radiological and biochemical parameters. Conclusion: Distribution, size, and pattern of COVID-19 related imaging findings differed in children and young adults. Radiological findings were correlated with biochemical parameters but not with blood count results of young adults
Active and Latent Tuberculosis in Children Treated with Anti-TNF-alpha: A Retrospective Multicenter Study
Objective This study aimed to investigate the frequency of latent and active tuberculosis (TB) in pediatric patients receiving anti-tumor necrosis factor (TNF)-alpha therapy
Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study)
Aim Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. Methods The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. Results The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 mu g/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. Conclusion The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management
