As one of the most common solid pediatric cancers, Neuroblastoma (NBL) accounts for 15% of all of the cancer-related mortalities in infants with increasing incidence all around the world. Despite current therapeutic approaches for NBL (radiotherapies, surgeries, and chemotherapies), these approaches could not be beneficial for all of patients with NBL due to their low effectiveness, and some severe side effects. These challenges lead basic medical scientists and clinical specialists toward an optimal medical interventions for clinical management of NBL.

Extreme hyperleukocytosis (Leukocyte count >200 × 10/L) in an adolescent young adult (AYA) patient with B-ALL could result in mild symptoms of leukostasis. Hyperleukocytosis requires prompt initiation of therapy with adequate hydration, cytoreduction and prevention of tumor lysis. Ph + B-ALL may present with extreme hyperleukocytosis and may be resistant to initial pre-phase therapy.

Neurology Department, Gülhane Training and Research Hospital, University of Health Sciences, Ankara, Turkiye.

Neurological disorders encompass a complex and heterogeneous spectrum of diseases affecting the brain, spinal cord, and peripheral nervous system, each presenting unique challenges that extend well beyond primary neurological symptoms. These disorders profoundly impact cardiovascular health, prompting an intensified exploration into the intricate interconnections between the neurological and cardiovascular systems. This review synthesizes current insights and research on cardiovascular comorbidities associated with major neurological conditions, including stroke, epilepsy, Parkinson's disease, multiple sclerosis, and Alzheimer's disease.

Introduction Tumor staging is essential for determining treatment strategies and predicting prognosis in cancer patients. Accurate imaging techniques are critical for staging, metastasis screening, treatment response assessment, and recurrence detection. Objective In this prospective study, we aimed to compare the sensitivity of whole-body diffusion-weighted imaging (WB-DWI) with positron emission tomography/computed tomography (PET/CT) in detecting metastases.

Background/aim: We aimed to investigate the relationship between serum antidrug antibodies (ADAbs), systemic hypersensitivity, or local injection site reactions to tumor necrosis factor (anti-TNF) drugs and to detect the role of skin tests in the diagnosis of hypersensitivity reactions (HSRs) against anti-TNFs.

Materials And Methods: Sixty-nine ankylosing spondylitis (AS) and 46 rheumatoid arthritis (RA) patients taking infliximab (IFX), adalimumab (ADA), and etanercept (ETN) were enrolled. The demographical data, erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP) levels of the patients were determined, and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) assessment for AS patients and DAS28 (disease activity score) for RA patients were assessed.

Growing teratoma syndrome (GTS) is characterized by a reduction in serum tumor markers despite the growth of a benign mature teratomatous mass following chemotherapy for germ cell tumors. Gliomatosis peritonei (GP) typically accompanies ovarian teratomas, marked by the dissemination of mature glial tissue across the peritoneum. The concurrent presence of GTS and GP after treatment for ovarian immature teratoma (IMT) is notably rare, with approximately 20 reported cases.

Phthalates and bisphenols, ubiquitous compounds found in various everyday products, have garnered attention due to their potential health-disrupting effects. This study aimed to (1) investigate urinary phthalate metabolites and bisphenol A (BPA) levels in donors and recipients prior to allogeneic hematopoietic stem cell transplantation (HSCT) and monitor changes in these compounds in pediatric recipients at different time points (Day-9, Day 0, Day+7, Day+28, Day+90), and (2) assess their association with engraftment success. Urine samples from pediatric recipients and donors were collected for analysis of phthalate metabolites and BPA in 34 donor-recipient pairs.

Objectives: Sialidosis type 1 is a rare autosomal recessive lysosomal storage disorder caused by pathogenic variants in the gene, which encodes the sialic acid-degrading enzyme α-neuraminidase. Sialidosis type 1 is a milder form with a late-onset phenotype, characterized by progressive myoclonic epilepsy and ataxia with cherry-red spots. Sialidosis type 2 is an early-onset and more severe form presenting with dysmorphic features, hepatosplenomegaly and cognitive delay.

Background And Aims: Insulin resistance is considered the most important key mechanism in the development of nonalcoholic fatty liver disease (NAFLD). Some studies have reported that hyperinsulinemia decreases the hepatic secretion of apolipoprotein (Apo) B. Chronic hyperinsulinemia in NAFLD may be responsible for the accumulation of triglycerides in hepatocytes.

This study evaluated the management of dyslipidemia in Turkey with the goal of understanding current diagnosis and treatment patterns, as well as identifying unmet needs in achieving effective low-density lipoprotein cholesterol (LDL-C) targets. Using a Delphi panel consisting of nine expert cardiologists, the study reveals key gaps in dyslipidemia management, particularly in the underutilization of combination therapies, such as statins and PCSK9 inhibitors, which are crucial for achieving LDL-C targets in high-risk patients. The findings indicate that while many patients with very high cardiovascular risk are diagnosed, a significant proportion do not receive optimal treatment to reach LDL-C levels recommended by European guidelines.

CD47 interacts with signal regulatory protein alpha (SIRPα) on macrophages to deliver an anti-phagocytic signal, enabling tumor cells to evade immune destruction. This study explores the relationship between CD47 and SIRPα expression and key clinical prognostic factors, microvascular density (MVD), and tumor-infiltrating lymphocytes (TIL) in Diffuse Large B Cell Lymphoma (DLBCL) cases. We analyzed tissue samples from 122 DLBCL cases using tissue microarray (TMA) blocks and immunohistochemical staining for CD47, SIRPα, CD31, and CD3.
