Color Duplex Doppler US can Follow up the Response of Radioiodine in Graves' Disease by Evaluating the Thyroid Volume and Peak Systolic Velocity.

PURPOSE: The objective of this study was to prove the efficacy of Doppler ultrasonography (US-Doppler) in the follow-up of patients with GD treated with radioactive iodine. METHODS: 97 patients (77 female and 20 male) with a mean age of 42 years (SD ±â€Š15) and with prior diagnosis of GD were treated with radioiodine. In total, 88.5 % achieved euthyroidism or hypothyroidism after treatment. The study was documented before treatment and one, three, and six months after treatment with radioactive iodine (131I) by a single investigator. The volume, echogenicity, echotexture and vascularization of the glands as well as the peak systolic velocity (PSV) of the inferior thyroid arteries were evaluated and compared with the laboratory data. RESULTS: Thyroid volume and PSV had a statistically significant correlation with hormone levels (p < 0.05). The mean pre-dose therapeutic thyroid volume was 43.01 ±â€Š3.88 cm3 and was 11.58 ±â€Š11.26 cm3 6 months after treatment. The mean PSV before 131I was 90.06 ±â€Š44.13 cm/s and decreased significantly over time (p < 0.001). Six months after the therapeutic dose, the mean PSV was 32.95 ±â€Š16.36 cm/s. However, the subjective parameters did not have a significant correlation with the normalization of the thyroid hormones. CONCLUSION: Doppler US was useful for monitoring the therapeutic response of GD patients after treatment with radioiodine by evaluating the thyroid volume and peak systolic velocity.

Polyacrylamide gel electrophoresis and combined immunoenzyme assay for rotavirus and adenovirus were used to analyze 380 fecal samples from children up to three years of age who were hospitalized with acute diarrhea in Campo Grande, State of Mato Grosso do Sul, between May 2000 and January 2004. Among all the samples, 88 (23.2%) were positive for Rotavirus A. Out of these, 81 (92%) had a defined electrophoretic pattern: 77 (87.5%) with a long pattern and four (4.5%) with a short pattern. Genotype G and P characterization was done by nested RT-PCR for 85 samples, of which 56 (65.9%) were genotyped as type G. Among these, 49 (87.5%) were G1, five (8.9%) were G4, one (1.8%) was G3 and one (1.8%) was G9. The genotype was found to be type P in 37 samples (43.5%) and all of these were P[8]. The G and P association most observed was G1P[8], with 33 samples (89.2%), followed by G4P[8], two samples (5.4%); G3P[8], one sample (2.7%); and G9P[8], one sample (2.7%).

Através da eletroforese em gel de poliacrilamida e do ensaio imunenzimático combinado para rotavírus e adenovirus, foram analisadas 380 amostras fecais de crianças com até 3 anos, hospitalizadas com diarréia aguda, entre maio de 2000 e janeiro de 2004, em Campo Grande, MS. Do total de amostras, 88 (23,2 por cento) foram positivas para Rotavirus A. Dentre essas, 81 (92 por cento) tiveram padrão eletroferotípico definido, sendo 77 (87,5 por cento) de padrão longo e quatro (4,5 por cento) de padrão curto. A caracterização genotípica G e P foi feita por RT-Nested-PCR para 85 amostras, sendo 56 (65,9 por cento) genotipáveis para genótipo G. Dentre essas, 49 (87,5 por cento) foram G1, cinco (8,9 por cento) G4, uma (1,8 por cento) G3 e uma (1,8 por cento) G9. Considerando a genotipagem P, 37 (43,5 por cento) foram genotipáveis e todas eram P[8]. A associação G e P mais observada foi G1P[8], 33 (89,2 por cento) amostras; seguida de G4P[8], duas (5,4 por cento) amostras; G3P[8], uma (2,7 por cento) amostra; e G9P[8], uma (2,7 por cento) amostra.
