BACKGROUND The specificity of childhood cancers led to the creation of regional childhood cancer registries. An epidemiological study of childhood cancers in the Auvergne area was carried out over a 6 year-period (1986-1991) in order to create a registry. POPULATION AND METHODS The population of our study was 252,820 children (0-15 years old), living in(More)
Serum immunoreactive calcitonin (iCT), serum immunoreactive parathyroid hormone (iPTH) and serum Ca, Mg, P and total protein levels were determined sequentially at 5 given periods of time from 1 to 48 h of age in 16 low birth weight infants. Mean +/- SD serum Ca levels decreased from 8.99 +/- 0.79 mg/100 ml at time 1--2 h to 7.00 +/- 0.51 mg/100 ml at time(More)
BACKGROUND Current recommendations for prophylaxis of Pneumocystis carinii pneumonia (PCP) are based on data from patients who have had at least one episode of PCP (secondary prevention). We designed a study to determine the efficacy and side effects of inhaled pentamidine in the primary prevention of PCP. METHODS Two hundred twenty-three patients(More)
BACKGROUND Aristolochic acid (AA) is a nephrotoxicant associated with AA nephropathy (AAN) and upper urothelial tract cancer (UUTC). Whole-genome sequences of 14 Romanian cases of renal cell carcinoma (RCC) recently exhibited mutational signatures consistent with AA exposure, although RCC had not been previously linked with AAN and AA exposure was(More)
The utility of KRAS mutations in plasma circulating cell-free DNA (cfDNA) samples as non-invasive biomarkers for the detection of pancreatic cancer has never been evaluated in a large case-control series. We applied a KRAS amplicon-based deep sequencing strategy combined with analytical pipeline specifically designed for the detection of low-abundance(More)
Human papillomavirus (HPV) causes oropharyngeal squamous cell carcinoma (OPSCC), although strongly divergent results have been reported regarding the prevalence of HPV16 in different countries, whether this represents important differences in etiology remains unclear. Applying rigorous protocols for sample processing, we centrally evaluated 1,420 head and(More)
Patients with AIDS but without pneumocystis carinii pneumonia, patients with advanced AIDS-related complex (ARC), and asymptomatic patients with less than 200 CD4-positive lymphocytes/mm3 were randomized to one of two groups: group I: Inhalation of 300 mg of pentamidine every 28 days; group II: Inhalation of placebo (300 mg of Na isethionate) every 28 days.(More)
