Case report: A case study of variant calling pipeline selection effect on the molecular diagnostics outcome.

Next-generation sequencing technologies have not only defined a breakthrough in medical genetics, but also been able to enter routine clinical practice to determine individual genetic susceptibilities. Modern technological developments are routinely introduced to genetic analysis overtaking the established approaches, potentially raising a number of challenges. To what extent is the advantage of new methodologies in synthetic metrics, such as precision and recall, more important than stability and reproducibility? Could differences in the technical protocol for calling variants be crucial to the diagnosis and, by extension, the patient's treatment strategy? A regulatory review process may delay the incorporation of potentially beneficial technologies, resulting in missed opportunities to make the right medical decisions.

Apixaban versus no anticoagulation for the prevention of venous thromboembolism in children with newly diagnosed acute lymphoblastic leukaemia or lymphoma (PREVAPIX-ALL): a phase 3, open-label, randomised, controlled trial.

Background: Paediatric patients with acute lymphoblastic leukaemia or lymphoma are at increased risk of venous thromboembolism resulting in increased mortality and morbidity. We hypothesised that apixaban, a direct oral anticoagulant, would safely reduce venous thromboembolism in this patient population.

Methods: PREVAPIX-ALL was a phase 3, open-label, randomised, controlled trial conducted in 74 paediatric hospitals in 9 countries.

DNA methylation-based diagnosis confirmation in a pediatric patient with low-grade glioma: a case report.

Central nervous system (CNS) tumors in children comprise a highly heterogenous and complex group of diseases. Historically, diagnosis and confirmation of these tumors were routinely based on histological examination. However, recently obtained data demonstrate that such a diagnostic approach is not completely accurate and could lead to misdiagnosis.

Effectiveness of metronomic chemotherapy in a child with medulloblastoma: A case report.

Medulloblastoma (MB) is one of the most common pediatric malignant tumors arising from the central nervous system with an unknown etiology and variable prognosis. Relapsed or refractory MB in pediatric patients after intensive anticancer therapy (chemo-, radiotherapy) is associated with treatment resistance and poor survival prognosis. Metronomic chemotherapy in combination with mTOR inhibitors may have advantages due to an alternate mechanism of cytotoxicity and a favourable adverse effects profile.

Presentation of severe brucellosis in 5-year-old boy - challenges and results.

Brucellosis is highly contagious zoonotic bacterial disease caused by gram-negative genus. It has a wide spectrum of clinical manifestations and due to variety and nonspecificity of clinical signs the diagnostics can be very complicated. We present a clinical case of severe chronic brucellosis in a 5-years old boy with long-term course of disease and multiorgan involvement.

Case report: Somatic mutations in microtubule dynamics-associated genes in patients with WNT-medulloblastoma tumors.

Medulloblastoma (MB) is the most common pediatric brain tumor which accounts for about 20% of all pediatric brain tumors and 63% of intracranial embryonal tumors. MB is considered to arise from precursor cell populations present during an early brain development. Most cases (~70%) of MB occur at the age of 1-4 and 5-9, but are also infrequently found in adults.

Case Report: Primary Leptomeningeal Medulloblastoma in a Child: Clinical Case Report and Literature Review.

Medulloblastoma is one of the most common pediatric central nervous system malignancies worldwide, and it is characterized by frequent leptomeningeal metastasizing. We report a rare case of primary leptomeningeal medulloblastoma of an 11-year-old Caucasian girl with a long-term disease history, non-specific clinical course, and challenges in the diagnosis verification. To date, 4 cases of pediatric primary leptomeningeal medulloblastoma are reported, and all of them are associated with unfavorable outcomes.

Efficacy of combined immunosuppression with or without eltrombopag in children with newly diagnosed aplastic anemia.

We compared the efficacy and safety of eltrombopag (ELTR) combined with immunosuppressive therapy (IST) and IST alone in treatment-naïve children with severe (SAA) and very severe (vSAA) aplastic anemia. Ninety-eight pediatric patients were randomized to receive horse antithymocyte globulin (hATG) and cyclosporin A (CsA) with (n = 49) or without (n = 49) ELTR. The primary endpoint was the overall response rate (ORR) at 4 months.

Ovarian tissue cryopreservation in prepubertal patients with oncological diseases: multidisciplinary approach and outcomes.

In children with cancer, the issues related to the quality of life are becoming increasingly important together with the improvement of survival rates. This creates an entirely new challenge - minimizing the toxicity of the antitumor therapy without reducing its effectiveness. One of the specific side effects of the antitumor therapy is gonadotoxicity, which negatively affects both the somatic and mental state of the survivors.
