[Mortality from renal causes of death in an Italian population under 20 years of age in the 1979-1991 period].

The present paper addresses mortality from urinary diseases (ICD9 codes 580-599) in the Italian pediatric population aged 0-19 years, in the period 1979-91. Mortality data were obtained from the Italian National Statistical Institute (ISTAT). A total number of 522 deaths were recorded among people aged 0-19 years, amounting to 0.33% of all casualties. Half of these deaths were due to renal failure (ICD9 codes: 584-586). While mortality from all causes decreased by 35% among the Italian pediatric population, mortality from urinary diseases remained stable during the same period, and even increased in the age range 0-4 years (from 3.47 per million person-years in 1979 to 9.83 per million person-years in 1990; p < 0.001). This outbreak in mortality was entirely due to an increase in casualties from acute renal failure (ICD9 code: 584). In conclusion, since the increase in mortality from urinary diseases among Italian children aged 0-4 years takes place in the presence of a substantial drop in mortality from all causes, attention should be paid to this problem and surveillance systems should be reinforced.
