SummaryBackgroundCancer is a major cause of death in children worldwide, and the recorded incidence tends to increase with time. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. This study aimed to provide internationally comparable local data on the incidence of childhood cancer to promote research of causes and implementation of childhood cancer control.MethodsThis population-based registry study, devised by the International Agency for Research on Cancer in collaboration with the International Association of Cancer Registries, collected data on all malignancies and non-malignant neoplasms of the CNS diagnosed before age 20 years in populations covered by high-quality cancer registries with complete data for 2001–10. Incidence rates per million person-years for the 0–14 years and 0–19 years age groups were age-adjusted using the world standard population to provide age-standardised incidence rates (WSRs), using the age-specific incidence rates (ASR) for individual age groups (0–4 years, 5–9 years, 10–14 years, and 15–19 years). All rates were reported for 19 geographical areas or ethnicities by sex, age group, and cancer type. The regional WSRs for children aged 0–14 years were compared with comparable data obtained in the 1980s.FindingsOf 532 invited cancer registries, 153 registries from 62 countries, departments, and territories met quality standards, and contributed data for the entire decade of 2001–10. 385 509 incident cases in children aged 0–19 years occurring in 2·64 billion person-years were included. The overall WSR was 140·6 per million person-years in children aged 0–14 years (based on 284 649 cases), and the most common cancers were leukaemia (WSR 46·4), followed by CNS tumours (WSR 28·2), and lymphomas (WSR 15·2). In children aged 15–19 years (based on 100 860 cases), the ASR was 185·3 per million person-years, the most common being lymphomas (ASR 41·8) and the group of epithelial tumours and melanoma (ASR 39·5). Incidence varied considerably between and within the described regions, and by cancer type, sex, age, and racial and ethnic group. Since the 1980s, the global WSR of registered cancers in children aged 0–14 years has increased from 124·0 (95% CI 123·3–124·7) to 140·6 (140·1–141·1) per million person-years.InterpretationThis unique global source of childhood cancer incidence will be used for aetiological research and to inform public health policy, potentially contributing towards attaining several targets of the Sustainable Development Goals. The observed geographical, racial and ethnic, age, sex, and temporal variations require constant monitoring and research.FundingInternational Agency for Research on Cancer and the Union for International Cancer Control.

Re-establishment of the cancer registry in Kyadondo County, Uganda, has allowed estimation of incidence rates for the period September 1989 to December 1991. The results are compared with earlier data from the same area, and from other African cancer registries. The most striking feature is the emergence of Kaposi's sarcoma as the leading cancer in males (almost half of all registered cases) and the second most frequent (17.9%) in females. This parallels the evolution of the epidemic of AIDS. There were also marked increases in the incidence of both oesophageal and prostatic carcinoma, while the incidence of cancer of the penis and the urinary bladder declined, possibly as a result of improved standards of hygiene. In females, the incidence of cancer of the cervix has more than doubled since the 1950s, and is now among the highest recorded in the African continent.

Background: Staphylococcus aureus, a mainly acquired hospital infection is responsible for many suppurative lesions and has demonstrated the ability of developing resistance to many antimicrobial agents leading to life threatening infections and long hospital stay. Objective: To determined the prevalence and antibiotic susceptibility of Staphylococcus aureus in suppurative lesions of the surgical ward and outpatients of Lacor Hospital (Uganda). Methods: A cross-sectional study was conducted at St. Mary's Hospital Lacor to determine the prevalence and antibiotic susceptibility profiles of Staphylococcus aureus in suppurative lesions in both surgical inpatients and outpatients. Using culture techniques on MacConkey and blood agar, Staphylococcus aureus was isolated based on the colonial characteristics and confirmed by Catalase and tube Coagulase tests. The antibiotic susceptibility test was done using Kirby-Buer disk diffusion method on 4% Salt Muellar Hinton II agar for the Methicillin and non salted Muellar Hinton II agar for the other antibiotics (NCCLS M100S9). Results: The prevalence of Staphylococcus aureus in 122 patients sampled was 59.4% for the surgical inpatients and 48.3% for outpatients giving an average prevalence of 53.9% for both groups of patients. The average antibiotic susceptibility patterns for the 8 antibiotic tested were: Ampicillin (75.0%), Chloramphenicol (34.4%), Ciprofloxacin (1.6%), Erythromycin (7.8%), Gentamycin (0%), Methicillin (1.6%), Tetracycline (45.3%) and Co-trimoxazole (50.0%). The resistance in surgical inpatients was significantly higher than outpatients (t=1299, p<0.05) and Methicillin resistance was confirmed by PCR. Conclusion: Staphylococcus aureus is highly prevalent and more resistant in inpatients. There is a higher risk of acquiring drug resistant staphylococcus aureus infection in inpatients of Lacor Hospital with a Methicillin resistance of 0% and 2.6% for out and inpatients respectively.
