OBJECTIVE: Paediatric laboratory reference intervals used in Africa and Asia may be derived from historical intervals of predominantly Caucasian infants in Europe or North America. These intervals may therefore not be compatible with the range of normality for developing country populations. We aimed to compare haematology and biochemistry parameters in healthy South African infants with local laboratory reference intervals. METHODS: We compared the baseline haematology and biochemistry results of 634 (316 male and 318 female) HIV-unexposed infants, aged 3-6 months, living in a rural area of the Western Cape Province, South Africa, against laboratory reference intervals supplied by the South African National Health Laboratory Services (NHLS)...

INTRODUCTION: Individuals can be exposed to gonadotoxic agents in the course of treatment for cancers and other medical conditions. Fertility preservation refers to strategies that aim to preserve fertility by protecting it against the damage inflicted by gonadotoxic treatment. Many young patients are prescribed gonadotoxic treatment without prior counselling. This study aimed to study the awareness of, attitude to, and knowledge about fertility preservation among clinicians in Hong Kong...

BACKGROUND: Studies of family history of cancer in paediatric germ cell tumours (GCTs) are few, and none has had sufficient sample size to specifically evaluate family history of GCT. METHODS: We utilised family history data from a paediatric GCT study to calculate standardised incidence ratios (SIR) for GCT and other cancers using age- and sex-specific incidence rates from the SEER Program. RESULTS: This analysis included 7998 relatives of paediatric GCT probands...

BACKGROUND: Prior to commencing antiretroviral therapy (ART), haematological abnormalities are a common occurrence in individuals diagnosed with human immunodeficiency virus (HIV). In the course of receiving ART, these abnormalities usually improve. We determined the prevalence of haematological abnormalities in children diagnosed with HIV-1 and the changes in haematological parameters that occur after 6 and 12 months of being on ART. METHODS: A cross-sectional study of HIV-1 infected children aged 2 months to 15 years, between July 2005 and March 2013, at the paediatric HIV clinic of the Jos University Teaching Hospital, Jos...

BACKGROUND: Dose-escalation trials aim to identify the maximum tolerated dose and, importantly, the recommended phase II dose (RP2D) and rely on the occurrence of dose-limiting toxicities (DLTs) during the first treatment cycle. Molecularly targeted agents (MTAs) often follow continuous and prolonged administrations, displaying a distinct toxicity profile compared to conventional chemotherapeutics, and classical DLT criteria might not be appropriate to evaluate MTAs' toxicity. We investigated this issue in children...

INTRODUCTION: Noonan syndrome (NS) is an autosomal dominant disorder characterized by short stature, skeletal and haematological/lymphatic defects, distinctive facies, cryptorchidism, and a wide spectrum of congenital heart defects. Recurrent features also include variable cognitive deficits and behavioural problems. Recent research has been focused on the assessment of prevalence, age of onset and characterization of psychiatric features in this disorder. Herein, we evaluated the prevalence of attention deficit and hyperactivity disorder (ADHD), anxiety and depressive symptoms and syndromes in a cohort of individuals with clinical and molecular diagnosis of NS...

BACKGROUND: The reported incidence of childhood cancer in upper-middle-income South Africa (SA) is much lower than in high-income countries, partly due to under-diagnosis and under-reporting. Documented survival rates are disturbingly low, prompting an analysis of potential factors that may be responsible. OBJECTIVES: To determine final-year medical students' level of knowledge of early warning signs of childhood cancer and whether a correlation existed between test scores and participants' age, gender and previous exposure to a person with cancer...

OBJECTIVES: This randomized controlled trial tested the hypothesis that children with non-high risk acute lymphoblastic leukemia could benefit from individualized 6-mercaptopurine increments during consolidation therapy (NCT00816049). Primary and secondary end points were end of consolidation minimal residual disease (MRD) positivity and event-free survival. METHODS: 392 patients were randomized to experimental and 396 to standard therapy. Patients allocated to standard therapy received oral 6-mercaptopurine (25 mg/m(2) /day) from days 30 to 85, while the experimental arm received stepwise increments of additional 25 mg/m(2) /day beginning on days 50 and/or 71 unless dose-limiting myelosuppression had occurred...

Primary Intestinal Lymphangiectasia (PIL) is a rare disease of unknown aetiology which presents in the paediatric age group with anasarca, diarrhoea, hypoproteinaemia, lymphoedema and chylous effusions. Tuberculosis, filariasis, chest trauma, malignancies and haematological disorders usually contribute to most cases of secondary lymphangiectasia and chylous effusions. We hereby describe a case of PIL presenting with chylous effusions which remained undiagnosed for eight years.

Osteoporosis in childhood is uncommon, and it may be secondary to a spectrum of diverse conditions. Idiopathic juvenile osteoporosis is a primary osteoporosis of unknown aetiology present in previously well children and is a diagnosis of exclusion. We describe a 10-year-old prepubertal boy who presented with back pain of 1-week duration. His spinal X-ray showed generalised loss of vertebral body heights in keeping with osteoporosis. Endocrine and haematological work-up were normal. He was treated with vitamin D supplement and intravenous pamidronate...

BACKGROUND: Neuroblastoma (NB) is the most common extracranial solid tumour in children. This is a very rare disease with heterogeneous biology varying from complete spontaneous regression to a highly aggressive tumour responsible for 15% of malignancy-related death in early childhood. Analyses of survival rates in Europe have shown a considerable difference between Northern/Western and Eastern European countries. Treatment results of NB in Lithuania have never been analyzed. AIM: To assess the survival rate of children with NB according to initial spread of the disease, age at diagnosis, the MYCN amplification, risk group, and treatment period...

OBJECTIVES: To establish the current use of granulocyte transfusions in haematology patients and explore interest in further research. BACKGROUND: Granulocytes may be used for the treatment of severe infection in neutropenic patients or for primary or secondary prophylaxis. Clinical utility of granulocyte transfusions is unclear, and recent studies have demonstrated equivocal outcomes. Pooled granulocytes are the main granulocyte product used in England and Wales, but there are no data on the patterns of use and little consensus on accepted indications...

Michele M Pasierb, Stephen P Seslar
In critically ill children, multi-organ-system disease can influence the choice of antiarrhythmic medication. Intravenous therapy is often necessary. There is a scarcity of paediatric critical-care cases demonstrating the dosing, monitoring, and efficacy of intravenous sotalol. This case demonstrates the effective use of intravenous sotalol in an adolescent with renal, hepatic, and haematological dysfunctions.

Lymphoma patient presenting with isolated third nerve palsy is relatively rare, and diagnosis of underlying disease may be challenging. Until this date, less than 20 cases have been described in the literature. This is the case of a 3-year-old boy who presented to neurologist with ptosis of left eye for 8 days. On examination, abdominal mass was detected, and the child was referred to paediatric surgery department. Laparotomy and excision of the mass was done. Histopathology and immunohistochemistry of the mass confirmed it to be a case of Burkitt's lymphoma...

BACKGROUND: Colour vision of candidates is tested in many medical colleges in India at the time of admission to undergraduate courses; however, there are no guidelines, and therefore no counselling, on how students with congenital colour vision deficiency (CCVD) should negotiate the medical course, and how best they can practise safely after graduation. Problems in interpreting coloured signs may lead to misdiagnosis. This study aimed to explore difficulties during clinical work that requires colour discrimination, and to offer suggestions on safe practice based on the findings and a review of the literature...
