Purpose: Throughout a child's cancer treatment, health professionals (HPs) constitute an important source of support for the entire family. However, the understanding of their presence and essential attributes is unclear. This study explored HPs' presence and attributes in connecting with parents and identified facilitators and barriers for connectedness.

Objectives: Childhood cancer often presents with non-specific signs and symptoms that might mimic non-malignant disorders including musculoskeletal diseases, potentially leading to rheumatic and orthopaedic misdiagnoses. We aimed to compare clinical presentation, diagnostic interval and survival in paediatric acute myeloid leukaemia (AML) with and without initial musculoskeletal symptoms.

Methods: This nationwide retrospective, cohort study reviewed medical records of 144 children below 15 years diagnosed with AML in Denmark from 1996 to 2018.

Objective: Childhood spinal tumors often present with musculoskeletal symptoms, potentially causing a misdiagnosis and delays in diagnosis and treatment. This study aims to identify, characterize, and compare children with spinal tumors who had prior musculoskeletal misdiagnoses to those without, analyzing clinical presentation, diagnostic interval, and outcome.

Study Design: This retrospective cohort study evaluated all children aged 0-14 years diagnosed with a spinal tumor in Denmark from 1996 to 2018.

Purpose: Parents of children/adolescents with cancer are placed in a state of severe suffering due to serious concerns, fears, and radical daily life changes. Human support is an important source of support for successful coping. This study explored fundamental aspects of parents' daily, social, and personal life during their child's treatment to deepen our understanding of 'who' plays a significant role in supporting parents, and how, and to what extent this support is provided.

Article Synopsis
  • * Results revealed that 10% of the children had harmful variants in known cancer genes, and these individuals had a higher likelihood of specific tumor types and multiple CNS tumors.
  • * The researchers found that genes linked to childhood cancers are more evolutionarily constrained than those associated with adult cancers, suggesting a significant genetic component in the etiology of pediatric CNS tumors.

Purpose: Cerebellar mutism syndrome (CMS) is a severe neurological complication of posterior fossa tumour surgery in children, and postoperative speech impairment (POSI) is the main component. Left-handedness was previously suggested as a strong risk factor for POSI. The aim of this study was to investigate the relationship between handedness and the risk of POSI.

Objectives: Survival among children diagnosed with acute lymphoblastic leukaemia (ALL) has increased considerably. However, morbidity in survivors constitutes a potential increasing burden not limited to secondary health care. Our objectives were to compare health care utilisation, including both primary and secondary health care, between childhood ALL survivors and matched references up to 15 years after curative treatment.

Objectives: To investigate health care utilisation including both primary and secondary health care 6 months before the diagnosis of a relapse or a second malignant neoplasm (SMN) in survivors of childhood acute lymphoblastic leukaemia (ALL).

Design And Setting: A Danish population-based matched cohort study linking multiple nationwide registries.

Participants: Participants were recruited from a total of 622 childhood ALL 2.

Maintenance therapy containing methotrexate and 6-mercapto - purine is essential to cure acute lymphoblastic leukemia (ALL). Cytotoxicity is elicited by incorporation of thioguanine nucleotides into DNA (DNA-TG), and higher leukocyte DNA-TG is associated with increased relapse-free survival. As 6-thioguanine provides 6- fold higher cytosolic levels of thioguanine nucleotides than does 6- mercapto purine, we added low-dose 6-thioguanine to methotrexate/6- mercapto purine maintenance therapy to explore if this combination results in significantly higher DNA-TG.

Background: Candidemia is the most frequent pediatric fungal infection, but incompletely elucidated in population-based settings. We performed a nationwide cohort study including all pediatric patients with candidemia in Denmark from 2004 to 2014 to determine age, incidence, species distribution, underlying diseases, patient management and outcomes.

Methods: All candidemia episodes were identified through the active nationwide fungemia surveillance program.

Nausea and vomiting are burdensome side effects of chemotherapy. Vomiting is observed in up to 60% of treated children. An appropriate and effective antiemetic regimen has the potential to eradicate or reduce the symptoms.
