RESUMO
Aim: To compare the efficacy and safety of ferrous ascorbate and colloidal iron in children with iron deficiency anemia. Study Design: An open, randomized, comparative, parallel-group study. Place and Duration of Study: Department of Pediatric Medicine of ‘Nilratan Sircar Medical College and Hospital’, Kolkata, India, between January 2009 and February 2010. Methodology: Children between the age group of 6 months to 12 years were included if they had anemia defined as hemoglobin <10 gm%. Children received treatment with either ferrous ascorbate or colloidal iron for 12 weeks. Each child received elemental iron 3 mg/kg body weight/day. Follow-up assessments were performed at the end of week 4, week 8 and week 12. Results: Out of the 137 children screened, 80 were included in the analysis. The mean rise in hemoglobin at the end of the 12 weeks was significantly higher in ferrous ascorbate group than colloidal iron group [3.24 ± 1.66 gm% vs. 1.42 ± 2.04 gm%; p <0.01]. Responder rate (hemoglobin ≥11.5 gm%) after 12 weeks of therapy was 53.57% in ferrous ascorbate group versus 10.34% in colloidal iron group; p<0.01. Conclusion: The study provides evidence for the role of ferrous ascorbate as an efficient oral iron supplement in the treatment of iron deficiency anemia in children.
RESUMO
We report 13 chromophobe renal cell carcinomas (10.8%) observed among 120 renal cell carcinomas in adults. The average age was 53 (range: 34-72) years old, and 6 were males and 7 females. The mean tumor size was 10 (range: 5-17) cm, mean nuclear grade 2.4, and mean Robson's stage was 1.9. There were two distinct histologic variants; typical variant (n=9) and eosinophilic variant (n=4). Both of them showed typical light microscopic features and positive reaction with Hale's colloidal iron and carbonic anhydrase II, a marker protein of intercalated cells of renal collecting ducts. A strong positive immunoreactivity for epithelial membrane antigen was noted in the cytoplasm in 12 of 13 tumors. Numerous microvesicles, 180~440 nm in diameter, were identified ultrastructurally. DNA aneuploidy was found in 3 out of 10 cases. Neither local recurrence nor metastasis have been identified during the following period of 4~144 (mean 48) months.
