Internet addiction and depression: a study among adolescents.

Objective: The goal of our study is to determine the level of Internet addiction (IA) in adolescents by utilizing the IA scale.

Methods: We employed two tools: the IA test (IAT) and the beck depression inventory (BDI), complemented by a sociodemographic information form, to assess IA and depression levels.

Results: A total of 201 participants were included.

The relationship between nutrition and micronutrients in healthy Turkish infants and young children.

Background: A healthy diet is important at every stage of life. We aimed to determine the serum vitamin D and iron, folic acid, and vitamin B levels in healthy children younger than 48 months and to investigate the relationship between nutrition and micronutrients in children of this age.

Methods: In this observational study children who presented to the Pediatrics Clinic of our hospital during the period 2015-2022 were included.

Diagnostic performance of routine blood parameters in periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome.

Background: We aimed to investigate the difference between PFAPA and streptococcal tonsillitis (Strep Pharyngitis) by using blood parameters. We want to evaluate the relationship between periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome, and tonsillitis by using NLR.

Methods: The data of 141 pediatric patients who had applied to our clinic between October 2016 and March 2019 and were diagnosed with PFAPA syndrome and tonsillitis were reviewed from hospital records.

Intravenous Immunoglobulin: A Good Choice for Acute Cerebellar Ataxia Associated with Varicella.

Postinfectious cerebellar ataxia is the most common cause of acute ataxia in childhood. The most frequently associated viral agent is varicella. Acute cerebellar ataxia is considered benign, and its symptoms usually diminish within several weeks.

Immunohistochemical HER2 Status Evaluation in Breast Cancer Pathology Samples: A Multicenter, Parallel-Design Concordance Study.

Objective: As patients with increased human epidermal growth factor receptor (HER2) overexpression are more likely to benefit from trastuzumab treatment, the accuracy of HER2 receptor status in breast cancer patients is significant for appropriate disease management. However, this assessment is not harmonized and results may be highly variable between centers. The aim of this study was to investigate the degree of interlaboratory variability in the results of HER2 expression reported by 5 participating centers and to assess the concordance between these centers and a reference laboratory.
