    A retrospective review of the prevalence and management of anaemia in children in at Red Cross War Memorial Children's Hospital
    (2015) Wege, Martha Helena; Hartley, Patricia; Muloiwa, Rudzani
    Introduction Childhood anaemia is a major public health problem, iron deficiency being most common. WHO estimates anaemia to occur in 24.1% of pre-school South African children. Our study describes prevalence and management of anaemia in children aged 6 - 36 months presenting to a children's hospital. Methods In a retrospective cross-sectional study, laboratory data were used to estimate prevalence of anaemia in children aged 6 - 36 month presenting to medical emergency or ambulatory services of Red Cross Children's Hospital in 2012. A random sample of 50% of anaemic children was sampled for detailed review. Results 2661 subjects were included. Anaemia (H b < 10.5) was found in 40.8 % (1088/2661. Children presenting to medical emergency had a higher prevalence of anaemia compared to those presenting to ambulatory services ( 42.7% vs. 34.9 % ; p=0.001 ). Anaemia prevalence increased with decreasing age with RR 1.25 (95% CI 1.10 - 1.43) and RR 1.15 (95% CI 1.02 - 1.31) in children aged 6 - 11 months and 12 - 23 months respectively compared to children aged 24 - 36 months. Microcytosis was found in 51.3% (558/1088) of anaemic children and in 19.3% (n=303/1573) of children without anaemia ; p<0.001 Folders were reviewed i n 502 children with anaemia , 36.1% had mild anaemia (Hb 10 - 10.5g/dl), while moderate ( Hb 8 - 10 g/dl ) and severe ( Hb < 8 g/dl ) anaemia was found in 52.5% and 11.4% respectively. Breastfeeding for longer than six months was associated with higher risk of microcytic anaemia [RR 1.26 (95%CI 1.08 - 1.47)]. Only 12.2 % (31 /254) of children with microcytic anaemia received adequate iron therapy, 50.0 % (127/254) received no iron therapy. Conclusions Prevalence of anaemia in children presenting to hospital is higher than predicted for well children in South Africa. The risk is higher in younger and acutely sick children. Prolonged breasting is associated with increased risk of microcytosis. Most children with suspected iron deficiency anaemia did not receive appropriate treatment.

    The evolving management of Burkitt's lymphoma at Red CrossChildren's Hospital
    (2006) Davidson, Alan; Desai, Farieda; Hendricks, Marc; Hartley, Patricia; Millar, Alastair; Numanoglu, Alp; Rode, Heinz
    Background. Treatment for Burkitt’s lymphoma at Red Cross Children’s Hospital has evolved from the use of aggressive surgery and less intensive chemotherapy to a conservative surgical approach with more intensive chemotherapy. Methods. The study was a retrospective folder review of patients diagnosed with Burkitt’s lymphoma at RCCH between 1984 and 2004. Results. Ninety-two children were treated for Burkitt’s lymphoma at RCCH between 1984 and 2004. There were 10 patients with group A or fully resected disease, 52 with group B or extensive localised disease, and 30 with dissemination to the bone marrow and/or central nervous system or group C disease. Protocol 1 (less intensive chemotherapy based on the COMP regimen) was used from 1984, with protocol 2 (more intensive chemotherapy based on the LMB regimen) introduced in 1988 for group C disease, 1991 for group B disease and 1996 for group A disease. Overall 5-year survival increased from 20% with protocol 1 to 66% with protocol 2 for group C disease, and from 76.5% with protocol 1 to 88.2% with protocol 2 for group B disease. There were more admissions for neutropenic fever in patients on protocol 2 and more episodes of mucositis, and these patients required more red cell and platelet transfusions. With a more conservative surgical approach, biopsy largely replaced attempts to partially resect the tumour at primary surgery, and there was a consequent decline in surgical complications. Conclusions. Intensive chemotherapy with protocol 2 has resulted in improved survival for group C and group B patients, but with more morbidity. Protocol 1, which is less intensive with less morbidity, remains a viable strategy for group A and group B disease in resource-poor settings.
