To identify the differences between the RSV and non-RSV bronchiolitis in hospitalized infants in a Greek tertiary pediatric unit and the possible risk factors related to severe forms of the illness. We performed a retrospective cross-sectional data analysis by reviewing medical records of patients that were hospitalized for acute bronchiolitis from 2012 to 2019. The patients with RSV bronchiolitis were found to require antibiotic treatment, IV fluids, adrenaline, and hypertonic saline inhalations more frequently than the non-RSV patients. They also required prolonged hospitalization, especially those that were admitted to PICU, and received oxygen therapy for longer periods. We searched risk factors for severe forms of the disease according to the need for admission to PICU, the supplemental oxygen and the extended length of hospital stay, concurrently. The patients with RSV bronchiolitis developed more severe illness in comparison with patients with bronchiolitis due to other respiratory viruses.
In the last 10 years, an increased number of patients presenting with acute encephalitis is being observed, a finding that is attributed to autoimmune mechanisms.Despite the fact that autoantibodies usually target the neuronal cell surface or synaptic proteins in the central nervous system (CNS), in many cases these remain undetectable, constituting a future diagnostic and therapeutic challenge. Human herpesvirus-7 (HHV-7) is proven to be a neurotropic virus, causing various neurological complications mostly in the adult population. We present the case of a 10-year-old girl, with confirmed active HHV-7 infection of the CNS, who developed acute seronegative autoimmune encephalitis. To our best knowledge, there is no literature concerning pediatric cases of autoimmune encephalitis following HHV-7 infection.
Primary thyroid lymphoma (PTL) is a rare thyroid gland cancer, with diffuse large B-cell lymphomas (DLBCL) being extremely rare in children and adolescents. Thus, optimal therapy is debatable. We describe a rare case of thyroid DLBCL in an adolescent girl with a history of Hashimoto thyroiditis (HT), the difficulty in diagnosis and the outcome of treatment. A 12-year-old girl with a nine-year history of HT was admitted with a right-sided painless progressive swelling of the neck. Physical examination and imaging including ultrasound (US), computed tomography (CT) and positron emission tomography/CT revealed an enlarged thyroid gland with right side lymphadenopathy and no metastasis. Two fine needle aspirations were done showing suspected lymphoblastic lesions for non-Hodgkin lymphoma without precise diagnosis. US guided core needle biopsy was finally performed confirming the diagnosis of DLBCL. She was treated according to LMB 96-group B protocol with no surgical removal of thyroid. The patient responded very well to treatment and 14 months later there is no evidence of relapse or metastases. PTL is an extremely rare cause of thyroid malignancy in children. However, it should be considered in the differential diagnosis of a thyroid mass in adolescents presenting with a rapidly enlarging neck mass and a history of HT. It is a treatable condition with a good prognosis, even in aggressive histological subtypes, with no need for thyroidectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
