Iodine deficiency in Calabria: Characterization of endemic goiter and analysis of different indicators of iodine status region-wide
摘要:
The distribution of goiter prevalence in schoolchildren (no.=13,984, age 6-14 yr), the neonatal TSH results obtained from the congenital hypothyroidism screening program and the urinary iodine excretion values (no.=284) were employed for the assessment of iodine deficiency in Calabria, a Southern Italy region. Data were collected during the years 1990-1996. In the inland territory, goiter prevalence ranged from 19 to 64%. At sea level, there was a great variability of goiter prevalence, with values varying from 5.3 to 25.7%. The analysis of the neonatal hypothyroidism screening program data (no.=21,078) showed a 14.8% frequency of TSH levels >5 muU/ml whole blood in newborns from the inland territory and a 14.1% frequency at sea level. Urinary iodine excretion resulted (mean+/-SD) 53.8+/-43.4 mug/l (range: <20 to 189 mu g/1) in the inland territory and 89.6+/-59.8 mu g/l (range: 26 to 333 mu g/l) at sea level. Median urinary iodine excretion values in 13 villages or small towns of the inland territory ranged from 31 to 57 mu g/l. In 2 major towns located at sea level, the median iodine excretion values were 72 mu g/l in Crotone main city and 94 mu g/l in Reggio Calabria main city. The data indicated that moderate, with pockets of severe iodine deficiency is present in the inland region while iodine supply varies from sufficient to marginally low in the coastal areas. Mild iodine deficiency was found in a major town located at sea level.

An efficient copper-catalyzed synthesis of N-substituted isatins has been developed in good yields from easily accessible arylacetamides. A wide range of electronically and structurally varied nitrogen fragments could be assembled through this tandem C–O/C–N bond-forming process by tuning the reaction conditions.
