Implemented nutritional intervention algorithm in pediatric oncology compared to standard nutritional supportive care outcomes.

Aim: To implement a childhood cancer-specific nutritional algorithm adapted for the South African context for interventions at time-set intervals to evaluate differences in the nutritional status of newly diagnosed children with cancer.

Method: Children with newly diagnosed cancer were assessed for stunting, underweight, wasting, and moderate to severe malnutrition (MUAC < -2SD and < - 3 SD) between October 2018 and December 2020 in a longitudinal nutritional assessment study with monthly assessments. Two pediatric oncology units (POUs) served as the intervention group that implemented the nutritional algorithm-directed intervention and three other POUs formed the control group that implemented standard supportive nutritional care.

Stem Cell Transplant in Immune-deficiency-associated Vaccine-derived Poliovirus.

Patients with severe primary immunodeficiency are at risk for complications from live-attenuated vaccines. Here, we report a case of a vaccine-associated paralytic polio and Bacille Calmette-Guérin disease in a 6-month-old girl with severe combined immunodeficiency resulting from homozygous recombinant activating gene 1 deficiency. The patient was successfully treated with intravenous immunoglobulins and oral pocapavir for poliovirus, and antimycobacterial therapy for regional Bacille Calmette-Guérin disease, allowing stem cell transplant.

The Utility of Metabolic Parameters on Baseline F-18 FDG PET/CT in Predicting Treatment Response and Survival in Paediatric and Adolescent Hodgkin Lymphoma.

Lymphoma is the third most common paediatric cancer. Early detection of high-risk patients is necessary to anticipate those who require intensive therapy and follow-up. Current literature shows that residual tumor avidity on PET (Positron Emission Tomography) following chemotherapy corresponds with decreased survival.

Reporting Incidences of Neuroblastoma in Various Resource Settings.

Purpose: The incidences of neuroblastoma (NB) differ significantly between various resource settings because of varying quality of cancer registries and underdiagnoses. This study aimed to evaluate current regional variations as reported by international cancer registries and the theoretical and reported differences in international NB incidences and to evaluate South Africa (SA) as a case for variable reporting.

Methods: A comprehensive literature review on registries reporting on NB was performed to construct incidence tables.

Travel burden and clinical presentation of retinoblastoma: analysis of 1024 patients from 43 African countries and 518 patients from 40 European countries.

Background: The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.

Methods: A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.

Endocrine profiling in patients with Fanconi anemia, homozygous for a FANCG founder mutation.

Background: Fanconi anemia (FA) is phenotypically diverse, hereditary condition associated with bone marrow failure, multiple physical abnormalities, and an increased susceptibility to the development of malignancies. Less recognized manifestations of FA include endocrine abnormalities. International discourse has highlighted that these abnormalities are widespread among children and adults with FA.

Global Retinoblastoma Presentation and Analysis by National Income Level.

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale.

Torsion of a bifid omentum as a rare cause of acute abdomen: a case report.

Background: Omental torsion is a rare and very unusual cause of acute abdominal pain. If often mimics other acute pathologies and it is very difficult to diagnose preoperatively, which can lead to deterioration of the patient. It is seldom reported in the literature.

Nosocomial outbreak of hepatitis B virus infection in a pediatric hematology and oncology unit in South Africa: Epidemiological investigation and measures to prevent further transmission.

Background: Hospital-acquired hepatitis B virus (HBV) infection has been well described and continues to occur worldwide. Recent nosocomial outbreaks have been linked to unsafe injection practices, use of multi-dose vials, and poor staff compliance with standard precautions. This report describes a nosocomial outbreak that occurred in a pediatric hematology and oncology unit of a large academic hospital, the epidemiological investigation of the outbreak, and preventive measures implemented to limit further in-hospital transmission.

Investigating hepatitis B immunity in patients presenting to a paediatric haematology and oncology unit in South Africa.

Background: Hepatitis B is an important public health concern in South Africa (SA). The hepatitis B virus (HBV) vaccine was introduced into the South African Expanded Programme on Immunisation (EPI-SA) in 1995. There is no 'catch-up' programme in place.

Malignancies in South African children with HIV.

Objectives: In 2008 the South African Children's Cancer Study Group decided to review the epidemiology, management, and chemotherapy response of HIV-positive children with malignancy.

Methods: This is a retrospective analysis of data collected from the records of HIV-positive children diagnosed with malignancy at 7 university-based pediatric oncology units serving 8 of the 9 provinces in South Africa.

Results: Two hundred eighty-eight HIV-positive children were diagnosed with 289 malignancies between 1995 and 2009.
