RESUMEN

BACKGROUND: Information on adverse events (AEs) in hospitalised patients in developing countries is scanty. OBJECTIVE: To compare the magnitude and characteristics of inpatient AEs in a tertiary, not-for-profit healthcare facility in Kenya, using medical records review and incident reporting. METHODS: Estimation of prevalence was done using incidents reported in 2010 from a random sample of medical records for hospital admissions. Nurse reviewers used 18 screening criteria, followed by physician reviewers to confirm occurrence. An AE was defined as an unexpected clinical event (UE) associated with death, disability or prolonged hospitalisation not explained by the disease condition. The kappa statistic was used to estimate inter-rater agreement, and analysis was done using logistic regression. RESULTS: The study identified 53 UEs from 2 000 randomly selected medical records and 33 reported UEs from 23 026 admissions in the index year. The prevalences of AEs from medical records review and incident reports were 1.4% (95% confidence interval (CI) 0.9 - 2.0) and 0.03% (95% CI 0.012 - 0.063), respectively. Compared with incident reporting, review of medical records identified more disability (13.2% v. 0%; p=0.03) and prolonged hospital stays (43.4% v. 18.2%; p=0.02). CONCLUSIONS: Review of medical records is preferable to incident reporting in determining the prevalence of AEs in health facilities with limited inpatient quality improvement experience. Further research is needed to determine whether staff education and a positive culture change through promotion of non-punitive UE reporting or a combination of approaches would improve the comprehensiveness of AE reporting.

RESUMEN

OBJECTIVE: The aim was to determine relative frequencies of acute leukemia immunophenotypes using commonly expressed markers and to describe the clinicopathological characteristics. Design: This was a prospective cross-sectional study. SETTING: The study was based at Aga khan clinical laboratory department. SUBJECTS: One hundred and thirty two (132) consecutive blood and bone marrow specimens from patients suspected to have acute leukemia were analysed for cytomorphological characteristics and immunophenotyping. The clinical-pathological characteristics were also recorded. Immunological category was assigned using the EGIL criteria. RESULTS: There were 88 AML and 42 ALL patients analysed for immunophenotypes. Only tw cases of biphenotypic leukemia were found. The commonest overall AML morphological sub-type was AML-M2, 26 (29.5%). Majority of ALL cases were B-cell immunological sub-type (96.6%). Early pre-B phenotype constituted 62.07% and Common B-cell ALL 37.93%. There were only 4 cases of T-cell ALL. Majority of patients presented with anaemia with a median hemoglobin of 7.5g/dl (range 2-15g/dl). The median platelet count was 55 (range 4-462 x 10(9)/L). CONCLUSION: Immunophenotyping of acute leukemia is beneficial in accurate diagnosis of patients with these malignancies in this setup. T-cell ALL, AML-M6 and M7 are less frequent than what has been reported in most studies in Africa.

RESUMEN

OBJECTIVE: To assess the frequency and nature of adverse events to patients in selected hospitals in developing or transitional economies. DESIGN: Retrospective medical record review of hospital admissions during 2005 in eight countries. SETTING: Ministries of Health of Egypt, Jordan, Kenya, Morocco, Tunisia, Sudan, South Africa and Yemen; the World Health Organisation (WHO) Eastern Mediterranean and African Regions (EMRO and AFRO), and WHO Patient Safety. PARTICIPANTS: Convenience sample of 26 hospitals from which 15,548 patient records were randomly sampled. MAIN OUTCOME MEASURES: Two stage screening. Initial screening based on 18 explicit criteria. Records that screened positive were then reviewed by a senior physician for determination of adverse event, its preventability, and the resulting disability. RESULTS: Of the 15,548 records reviewed, 8.2% showed at least one adverse event, with a range of 2.5% to 18.4% per country. Of these events, 83% were judged to be preventable, while about 30% were associated with death of the patient. About 34% adverse events were from therapeutic errors in relatively non-complex clinical situations. Inadequate training and supervision of clinical staff or the failure to follow policies or protocols contributed to most events. CONCLUSIONS: Unsafe patient care represents a serious and considerable danger to patients in the hospitals that were studied, and hence should be a high priority public health problem. Many other developing and transitional economies will probably share similar rates of harm and similar contributory factors. The convenience sampling of hospitals might limit the interpretation of results, but the identified adverse event rates show an estimate that should stimulate and facilitate the urgent institution of appropriate remedial action and also to trigger more research. Prevention of these adverse events will be complex and involves improving basic clinical processes and does not simply depend on the provision of more resources.

RESUMEN

OBJECTIVE: To evaluate utility of C-reactive protein (CRP) in the early diagnosis of neonatal sepsis in a tertiary care Newborn Unit in Kenya. DESIGN: Cross-sectional study. SETTING: Newborn Unit, Kenyatta National Hospital. SUBJECTS: All neonates admitted to Newborn Unit, Kenyatta National Hospital during the study period with suspected sepsis based on specified clinical criteria. RESULTS: Of the 310 infants, there were 83 episodes of proven sepsis and 94 episodes of probable sepsis. Using the standard CRP cut-off value of 5 mg/dl, a sensitivity of 95.2% in proven sepsis and 98.9% for probable septic episodes were noted. In proven sepsis, a specificity of 85.3%, positive predictive value of 80.6%, and a negative predictive value of 96.5% were noted. In probable sepsis, a specificity of 83.3%, positive predictive value of 80.9% and a negative predictive value of 99.1% were noted. The overall accuracy in proven sepsis was 96.5%, and in probable sepsis was noted to be 99.1%. Sub-analysis showed a lower positive predictive value (61.5%) for early onset sepsis compared to 93% for late onset sepsis. Repeat CRP tests were done in 33 babies. Twenty two of the 29 with proven/probable infection had a ten-fold increase in CRP levels, but levels were noted to be low or reducing in seven (24.1%) babies showing signs of improvement clinically. Using a receiver operator characteristic curve, the optimal cut-off point for CRP was found to be 5 mg/dl. CONCLUSIONS: Serum CRP is an accurate indicator of neonatal sepsis, with high sensitivity, specificity and predictive values, at the standard cut-off of 5. CRP is a better screening test for late-onset than early-onset neonatal sepsis. The standard recommended CRP cut -off point of 5 is appropriate for local use.

RESUMEN

BACKGROUND: Road traffic injuries (RTI) are on increase in developing countries. Health care facilities are poorly equipped to provide the needed services. OBJECTIVE: Determine access and quality of care for RTI casualties in Kenya. DESIGN: Cross-sectional survey SETTING: 53 large and medium size private, faith-based and public hospitals. PARTICIPANTS: In-patient road traffic crash casualties and health personnel in the selected hospitals were interviewed on availability of emergency care and resources. Onsite verification of status was undertaken. RESULTS: Out of 310 RTI casualties interviewed, 72.3%, 15.6% and 12.2% were in public, faith-based and private hospitals, respectively. Peak age of the injured was 15-49 years. First aid was availed to 16.0% of casualties. Unknown persons transported 76.5% of the injured. Police and ambulance vehicles transported 6.1% and 1.4%, respectively. 51.9% reached health facilities within 30 minutes of crash and medical care provided to 66.2% within one hour. 40.8% of recipient facilities were adequately prepared for RTI emergencies. CONCLUSIONS: Most RTI casualties were young and from poor backgrounds. Training of motorists and general public in first aid should be considered in RTI control initiatives. Availability of basic trauma care medical supplies in public health facilities was highly deficient.

RESUMEN

BACKGROUND: Effectiveness and toxicity of childhood cancer treatments have never been evaluated in Kenya since introduction of structured care in the early seventies. OBJECTIVE: To evaluate effectiveness and toxicity of two treatment protocols for Non-Hodgkin's lymphoma (NHL). DESIGN: Historical cohort study using medical records. SETTING: Kenyatta National Hospital, a tertiary care and medical teaching hospital. SUBJECTS: Children < or =15 years with diagnosis of non-Hodgkin's Lymphoma. MAIN OUTCOME MEASURES: Primary outcomes were median survival, event free survival and toxicity. RESULTS: Out of 101 records, only 26 (25.7%) met inclusion criteria. Baseline characteristics were similar in the two treatment arms. Median survival was 0.75 months (95% CI = 0.54-0.96) and 1.0 months (95% CI = 0.29-1.71) for short and long arm groups. There was no difference in event free survival and haematological toxicity. CONCLUSION: No clear difference in effectiveness and toxicity between the intensive-short and the less aggressive long course chemotherapy regimens was evident. Though lack of difference may be attributed to the small sample size, suboptimal supportive care for intensive treatment would increase risk of toxic deaths. As the short course protocol did not demonstrate obvious deterioration of median and event free survival, a strong case may be made for a randomised clinical trial within a context of improved supportive care.

RESUMEN

OBJECTIVE: To determine clinical-pathologic characteristics, treatment modalities and treatment outcomes of children diagnosed with neuroblastoma. DESIGN: Cross-sectional descriptive study based on secondary data from patient records. SETTING: Records department of Kenyatta National Hospital (KNH), a tertiary teaching and referral hospital based in Nairobi. SUBJECTS: Children aged 15 years and below, admitted with the diagnosis of neuroblastoma, between January 1997 and December 2005. MAIN OUTCOME MEASURES: Presenting clinical features, diagnostic modalities including laboratory and imaging data, treatment modalities, response to treatment and patient survival. RESULTS: Twenty six patients were eligible for the study; 13 males and 13 females giving a M:F ratio of 1:1. The age range was 5 days to 12 years, with a median age of five years. Abdominal swelling (53.8%), inability to walk due to bone pains, (50%), and cranial or periorbital swelling, (38.5%) were the commonest presenting features. Diagnosis of neuroblastoma was based on tissue biopsy in 50% (95% CI 40.6-79.8%) of the patients, and on fine needle aspiration cytology of mass or bone marrow in the rest. Bone marrow involvement was present in 16, (75%). Anaemia, was common with 72.7% patients having a haemoglobin (HB) <8 g/dl at presentation. Immunohistochemistry and cytological grading were done in two, (8%), patients. Urinary vanilly 1 mandelic acid (VMA), screening was positive in 50% (95% CI 29.9%-70.1%). The most frequently involved organs were abdomen (88.9%), and skeleton, (84.6%). Majority of patients, (92.3%), presented with advanced stage IV disease. Three patients died before commencement of treatment. All treated patients (100%), received cytotoxic therapy. Only two patients (8.6%) had surgery as part of treatment while one, (4.3%) was treated with radiotherapy. The initial treatment regimen was similar for all the patients. Although most patients had a complete initial response to treatment, early relapse, treatment failure, death or loss to follow up of patients with progressive disease were common. Overall survival (OS) at one year and two years were 19.2% (95% CI 6.6-39.4%) and 7.7% (95% CI 0.9%-25.1%) respectively. Only one patient was alive, (also free of disease), five years after diagnosis. CONCLUSION: Although other clinical-pathologic findings of the patients were similar to those reported elsewhere, virtually all study patients presented with advanced stage IV disease, which would be associated with poor prognosis irrespective of quality of care. Priority must therefore be on ensuring early diagnosis and referral of patients with neuroblastoma before any other interventions can be expected to positively impact on outcome. The limited role of surgery and radiotherapy observed over the study period may be attributed to late presentation of the patients. Pathologic evaluation of important information could have been availed at minimal extra cost. To be at par with current internationally accepted treatment approaches that have been associated with improved survival, there is need to base choice of regimens for individual patients on clinical and readily accessible pathologic markers.

RESUMEN

OBJECTIVE: To determine the seroprevalence of varicella zoster in paediatric patients at a high risk of developing complications. DESIGN: A cross-sectional study. SETTING: Paediatric general wards at Kenyatta National Hospital. SUBJECTS: Children with malignancies, severe malnutrition and were HIV positive. INTERVENTIONS: The sample size was calculated at 147 subjects. Venous samples were tested for varicella zoster virus (VZV) antibodies using enzyme immunosorbent assay (ELISA) technique at Kenya Medical Research Institute (KEMRI) laboratories, The data were analysed using the SPSS software and presented in form of tables and graphs. The prevalence of VZV antibodies was determined and 95% confidence interval computed. RESULTS: The overall seroprevalence of VZV antibodies in the three groups of children studied was 23.6% (95% CI = 17.4, 29.8). The seroprevalence of VZV antibodies in those with malignancies and severe malnutrition was 24.1 and 25.0% respectively. About 22% of HIV positive children had protective levels of VZV antibodies. Though the seroprevalence increased with age, it was not significantly associated with area of residence, size of residence, family size or income. CONCLUSIONS: The low prevalence of protective VZV antibodies among children with severe malnutrition, malignancies and HIV infection children at Kenyatta National Hospital warrants routine immunisation of the high-risk population.

RESUMEN

OBJECTIVES: To identify bacterial isolates and determine antibiotic sensitivity pattern in children with severe Protein Energy Malnutrition (PEM) presenting at the Paediatric Filter Clinic (PFC) of Kenyatta National Hospital (KNH). DESIGN: Hospital based cross-sectional survey. SETTING: Paediatric Filter Clinic of Kenyatta National Hospital (KNH), a tertiary level teaching institution for the University of Nairobi, Kenya. SUBJECTS: Children between two and sixty months presenting at the hospital outpatient filter clinic with severe malnutrition. RESULTS: Ninety-one children, forty six female and forty five males, were recruited for the study. Of these, sixty had Marasmus, twenty Kwashiorkor and eleven Marasmic-Kwashiorkor. HIV serology was positive in 43% of study subjects. There were 30 bacterial isolates from 26 subjects. Ten bacterial isolates were gram positive and twenty gram negative. Isolation rates did not vary by HIV serological status. Twenty one out of the 30 isolates were from blood culture. About 1/3 of the gram positive isolates were coagulase negative staphylococci, largely resistant to commonly used antibiotics such as Erythromycin, Ampicillin, Cotrimoxazole, Chloramphenicol and even Oxacillin. More than half demonstrated resistance to commonly used oral antibiotics while 80% of all gram positive and negative isolates were sensitive to Ciprofloxacin. Aminoglycosides, Gentamicin and Amikacin, and third generation Cephalosporins, Ceftriaxone and Ceftazidime, were found to be effective against most gram-negative isolates. CONCLUSION: Nearly a third (28.9%) of children admitted with severe malnutrition at KNH have concomitant severe bacterial infections; primarily manifesting as bacteraemia. Gram-negative agents are responsible for most severe bacterial infections in children admitted at the KNH, regardless of their HIV serological status. Whenever possible, blood culture should be included in the initial septic screening of severely malnourished children at KNH. In the absence of culture and sensitivity information, ciprofloxacin should be considered among the first line options in the empirical treatment of severe bacterial infections among these children. Clinical trials to further evaluate in-vivo effectiveness of various single or combination antibiotics are recommended.

RESUMEN

BACKGROUND: Kenya has a soaring rate of road traffic fatalities. Available evidence suggests significant alcohol-relatedness to trauma. We know little about the prevalence of alcohol-related injuries in Nairobi. OBJECTIVE: To determine the extent and pattern of alcohol use in subjects admitted following road traffic accident. DESIGN: A descriptive hospital based survey. SETTING: Kenyatta National Hospital (KNH)- a university affiliated hospital in Nairobi, Kenya. RESULTS: The overall incidence of alcohol use was 26.3%. This was higher in males (29.6%) than females (9.1%). Use was 24.4%, 31.0%, 28.6% and 13.6% in the 16-25, 26-35, 36-45 and 46-55 age groups respectively. The mean ages, pre-hospital times and ISS were similar for the AUG and NAUG. The incidence of males, weekend injuries, night collisions, and pedestrian involvement was 94.4%, 69.4%, 41.7%, 77.8% in the AUG and 83.2%, 35.6%, 19.8% and 61.4% in the NAUG respectively. The incidence of head and extremity injuries in AUG was 27.8% and 50% respectively compared to 11.9% and 66.3% in the NAUG. Treatment costs were higher for the NAUG. CONCLUSIONS: The results suggest a high incidence and potential alcohol-relatedness to road trauma in Nairobi. The study calls for objective evaluation of the extent, interactions and effects of this modifiable trauma factor.

RESUMEN

Angio-oedema may be hereditary or acquired and is characterised by episodes of potentially life threatening localised tissue oedema and swelling resulting from deficiency of compliment pathway C1 esterase inhibitor. Acquired angio-oedema is about ten times less frequent than the hereditary type and has been associated with immune-deficiency disorders, malignancies and exposure to specific medications and food substances. We present a case of seven year old, human immune-deficiency virus positive girl, who developed gross swelling of the tongue and neck while on treatment for pneumococcal meningitis with ceftriaxone. Difficulties in arriving at a definitive diagnosis of angio-oedema in a resource poor country are discussed and alternative diagnostic options proposed.

RESUMEN

OBJECTIVE: To review the clinical presentation and management of children with nephroplastoma and the factors influencing the outcome at Kenyatta National Referral and Teaching Hospital (KNH). DESIGN: This was a retrospective case series study based on secondary data accumulated between 1990 and 1996. SETTING: The relevant data were extracted from records of all children aged 12 years and below, admitted for cancer at KNH, Nairobi. RESULTS: Out of 803 children with cancer, 71 (8.8%) had histologically proven nephroblastoma. At presentation, 1.5% were in stage I, 13.2% stage II, 36.8% stage III, 41.2% stage IV and 7.4% stage V. Eighty five per cent presented with stage III-V disease. Ninety five per cent had nepherectomy and received chemotherapy. Radiotherapy was given to 50.7% of the patients. Nine patients died before commencement of chemotherapy, two of whom died in the immediate post-operative period. The median duration between admission and surgery was 41 days. Pre-operative chemotherapy was given to 42% of the patients. Approximately 25.5% of the patients received little or no induction chemotherapy due to unavailability of drugs while only 2.8% received the prescribed maintenance treatment with the remainder getting erratic or no treatment. Overall, only 34.7% remained disease free two years from time of diagnosis. CONCLUSION: Late presentation, poor availability of cytotoxic drugs and frequent treatment interruptions for various reasons have contributed to the poor outcome of nephroblastoma in Kenya.

RESUMEN

OBJECTIVE: To ascertain the prevalence of iron deficiency anaemia(IDA) and its risk factors. DESIGN: A cross-sectional survey. SETTING: A peri-urban health centre in Nairobi, Kenya. SUBJECTS: Four hundred and three children, aged six months to six years. INTERVENTION: Demographic data were obtained and each child examined for signs of iron deficiency anaemia. Blood was drawn for haemoglobin determination. MAIN OUTCOME MEASURE: The diagnosis of iron deficiency anaemia was made using a pre-defined criteria. RESULTS: Iron deficiency anaemia had a prevalence of 7.4% (95% CI = 4.8-10.0) and was predominantly mild (93.6%). Age was found to be significantly associated with iron deficiency anaemia with a prevalence of (14.6%) in infants. No association was found between IDA and sex, birthweight, weaning age and weaning diet, sanitation, water source or mother's education. CONCLUSION: The prevalence of iron deficiency anaemia in this health facility was relatively low and was predominantly mild.


PIP: This cross-sectional survey, conducted in a periurban health center in Nairobi, Kenya, determined the prevalence of iron deficiency anemia (IDA) and its risk factors among 403 children aged 6 months to 6 years. Demographic data were obtained and each child was assessed for signs of IDA. Blood was drawn for hemoglobin determination. The diagnosis of IDA was made using predefined criteria. Findings revealed that the prevalence of IDA was 7.4% (95% confidence interval = 4.8-10.0) and was predominantly mild (93.6%). Age was found to be significantly associated with IDA, with a 14.6% prevalence rate in infants. No association was found between IDA and factors such as sex, birth weight, weaning age and weaning diet, sanitation, water source, or education of the mother. Although the study showed that IDA was not a major health problem in the area, as evidenced by the low prevalence rate and presence of only mild cases, there is still a need for emphasis on health education at the health facility since young children are at high risk of IDA.

RESUMEN

Neutropaenia and immunosuppression place children on treatment for malignancies at a high risk for infections. We undertook to determine the prevalence of urinary tract infection (UTI) in children on treatment for cancer at the Kenyatta National Teaching and Referral hospital. With the understanding that many laboratories in the rural areas of the country lack appropriate facilities for confirmation of UTI, it was also important to evaluate simple and inexpensive screening methods against a "gold standard" in this cross sectional study. One hundred and eighty six children between the ages of five and 14 years admitted in Kenyatta hospital with leukaemia or lymphoma were enrolled. Besides clinical evaluation, urinalysis and culture and sensitivity were performed on all the subjects. Urine culture was considered the "gold standard" for diagnosis for UTI. The prevalence of UTI was 8.1% (CI = 6.1, 10.1). Only five out of 15 patients were symptomatic. E. coli and klebsiella spp. were responsible for 93.4% of the infections. Presence of pyuria, defined as five or more pus cells per high power field, had a sensitivity of 80.0%, specificity of 97.1% and a positive predictive value of 70.6% while comparative values associated with a positive nitrite test were 60%, 97.7% and 96%. Other clinical and laboratory tests had low sensitivity. UTI is a relatively frequent infection in children on cancer treatment. Screening for pyuria is simple, inexpensive and an accurate method of diagnosing UTI in children on treatment for lymphohaematopoietic malignancies in situations where facilities for urine culture are unavailable.

RESUMEN

To identify child feeding behavior and household hygiene practices that are risk factors for prolonged diarrheal illness, a longitudinal community study was conducted over a 14-month period among 920 children aged 3-37 months who lived in an urban slum settlement in Nairobi, Kenya. Morbidity surveillance was done by home visits every third day in the absence of diarrhea and daily during diarrheal illness until termination of the episode. In-home observations were made to characterize maternal hygiene, cooking, and child feeding practices. Overall, 1,496 episodes of diarrhea were detected. The average diarrheal incidence was 3.5 episodes/child-year, and the incidence of diarrhea > 14 days was 3 episodes/100 child-years. Cox regression was used to examine the independent effects of covariates on time to recovery from a diarrheal episode. Adjusted behavioral factors that were observed to influence recovery from diarrhea included: uncovered water containers (rate ratio (RR) = 0.77, 95% confidence interval (CI) 0.64-0.94); giving no fluids (as opposed to oral rehydration solutions (ORS)/sugar salt solutions (SSS)) (RR = 1.42, 95% CI 1.14-1.77); and administration of diluted cow's milk during the first 3 days of an episode (RR = 1.23, 95% CI 1.00-1.52). These associations remained significant after adjusting for diarrheal severity. The authors recommend, among other measures, improvement of water storage and promotion of continued feeding with cereal-milk mix during diarrhea.

RESUMEN

The objective of this study was to evaluate knowledge, attitudes and beliefs (KAB) that may influence health seeking behaviour of caretakers of children with sickle cell disease (SCD). A cross-sectional survey was undertaken at Nyanza provincial hospital in Kenya between March and September 1993 to identify socio-demographic and economic factors that may influence health seeking behaviour of primary caretakers of children with SCD. All caretakers accompanying children under the age of 18 years to the Sickle Cell Clinic were eligible. Guardians accompanying children to the clinic were interviewed using pretested questionnaires. An exploratory factor analysis method was used to categorise questionnaire items into domains (knowledge, attitude and belief) and to investigate for association between certain socio-demographic factors and KAB. Seventy five per cent of the 108 respondents interviewed were mothers and 16.7% fathers. Seventy eight percent knew SCD to be hereditary while 55% knew how the disease presents in childhood. Only 42% associated SCD with increased risk of infection. Many felt severe infections are largely preventable and that prevention would reduce their anxiety and illness related costs. In factor analysis, variables loaded almost exclusively on "Attitudes" and "Beliefs" factors. Only family size was found to influence caretaker attitudes (p = 0.0095) and beliefs (p = 0.0034). Education, monthly income, occupation and religion had no significant influence. The majority of caretakers had good knowledge and positive attitudes towards SCD in children. Interventions aimed at management of SCD or prevention of its sequelae would be well accepted. Factor analysis is recommended for statistical analysis of KAB data. The effect of family size on attitudes and behaviour needs further evaluation.

RESUMEN

This was a cross-sectional survey in which 80 children with malignancies were studied at the Kenyatta National Hospital to determine cardiac status before and during cancer therapy. An equal number of age and sex matched subjects admitted to the surgical wards for minor procedures was recruited as a comparison group. All the subjects underwent clinical cardiac assessment. Chest radiographs, electrocardiograms (ECG), echocardiograms, haemograms and renal function tests were also performed. Overall, 13 cases (16.3%) had abnormal cardiac findings compared to 7 (8%) in the comparison group (p = 0.429). Sixteen, two and five subjects had abnormal velocity of circumferential fibre shortening, ejection fraction and pericardial effusion respectively. Three out of the five subjects with pericardial effusion were cancer patients who had not undergone treatment. Mitral valve prolapse with regurgitation was diagnosed in one cancer patient. Though not statistically significant, children with malignancies appear to have a higher frequency of acquired cardiac abnormalities than those without cancers. Since a larger proportion of the abnormalities occurred in cancer children before commencement of treatment, the pathology is more likely to have resulted from the malignancies than therapy. There was no evidence to suggest that cancer treatment contributed to cardiac morbidity. We recommend that all oncology patients undergo cardiac evaluation on admission.
