VOA News Examines Malaria In Southern Sudan
VOA News examines malaria in southern Sudan. In the region, malaria is "widespread" and accounts for "up to 30 percent of all diseases treated by health facilities." It is the "number one killer of children in southern Sudan," though there are "no reliable statistics on the number in southern Sudan who suffer, or die from, malaria," VOA News reports.

What Are Cataracts? What Causes Cataracts?
Cataracts are cloudy areas in the lens inside the eye - which is normally clear. Cataracts can develop in one or both eyes. If they develop in both eyes, one will be more severely affected than the other. A normally clear lens allows light to pass through to the back of the eye, so that the patient can see well-defined images. If a part of the lens becomes opaque light does not pass through easily and the patient"s vision becomes blurry - like looking through cloudy water or a fogged-up window. The more opaque (cloudier) the lens becomes, the worse the person"s vision will be.

Lifelong Cancer Risk For Patients Treated For Childhood Cancer

Childhood cancer survivors have a persistent and high risk for a second primary cancer throughout their lives, according to a new study published in the May 26 online issue of the Journal of the National Cancer Institute. Previous studies established that second primary cancer risk after treatment in childhood is higher than that in the general population, but follow-up was restricted to a few decades and the incidence in long-term survivors was rarely investigated. This study presents data for incidence of second cancers among childhood cancer patients in the Nordic countries over a full age range, from birth to age 79. In the study, JÃñrgen H. Olsen, M.D., of the Institute of Cancer Epidemiology, Danish Cancer Society, in Copenhagen, Denmark, and colleagues studied a cohort of 47,697 people who were diagnosed with cancer prior to the age of 20, from 1943 to 2005. Members of the cohort were followed for subsequent primary cancers listed in registries, and the age-specific risk pattern of the survivors was compared with that of the national populations using country and sex standardized incidence ratios (SIRs). The researchers found that the observed incidence rate of new primary cancers was higher than the expected rates, and the relative risk of second primary cancers was statistically significantly increased in all age groups. A total of 1,180 second primary cancers were observed in 1,088 persons, yielding a SIR of 3.3, with the brain as the most common site. They also found that the relative risk for second primary cancers in male survivors was statistically significantly higher than in female survivors. "This study quantified long-term temporal patterns of increased risk of cancer at specific sites in survivors of childhood cancer," the authors write. "The results may be useful in the screening and care of these individuals." Citation: Olsen et al. Lifelong Cancer Incidence in 47 697 Patients Treated for Childhood Cancer in the Nordic Countries.
