Nódulos de tireóide: valor da ultra-sonografia e da biópsia por pun o aspirativa no diagnóstico de cancer
Peccin Simone,Furlanetto Tania Weber,Castro José Augusto Sisson de,Furtado álvaro Porto Alegre
Revista da Associa??o Médica Brasileira , 2003,
Abstract: Os nódulos de tireóide s o um problema clínico comum e a pun o aspirativa por agulha fina (PAAF) é o principal exame utilizado para seu diagnóstico diferencial. Recentemente, foi demonstrado que algumas características ultra-sonográficas dos nódulos est o associadas a um maior risco de cancer. Entretanto, n o encontramos estudos que avaliassem o desempenho dos dois exames de forma comparativa e/ou complementar. OBJETIVO: Avaliar o desempenho da ultra-sonografia (US), da PAAF e de sua combina o no diagnóstico de cancer em nódulos de tireóide. MéTODOS: Oitenta pacientes com nódulos únicos ou dominantes, com indica o cirúrgica, foram selecionados dentre 289 pacientes com nódulos tireoidianos atendidos entre mar o de 1995 e julho de 1997. Os pacientes foram submetidos à PAAF e à US de tireóide por um dos autores. A PAAF foi considerada positiva quando os achados citológicos eram suspeitos ou diagnósticos de cancer. A US foi considerada positiva quando os nódulos apresentavam pelo menos um dos seguintes achados: microcalcifica es, hipoecogenicidade ou halo ausente. PAAF e US foram combinados em paralelo (o resultado positivo em qualquer um dos dois exames era considerado indicativo de malignidade) e em série (somente o resultado positivo de ambos os testes indicava presen a de malignidade). RESULTADOS: A sensibilidade e a especificidade da PAAF na detec o do cancer em nódulos de tireóide foram, respectivamente, 87% e 62%, e a sensibilidade e a especificidade da US foram, respectivamente, 81% e 70%. A combina o em série dos dois exames (PAAF e US) resultou em sensibilidade de 69% e especificidade de 91%, e a combina o em paralelo (PAAF ou US) apresentou sensibilidade de 94% e especificidade de 52%. CONCLUS O: A US pode ser útil na avalia o dos nódulos de tireóide, alternativamente ou em combina es com a PAAF. Como o resultado da US depende da experiência do operador e das características do equipamento, s o necessários estudos em diferentes centros para o seu uso na prática clínica.

Abstract: background: thyroid nodules are a very common clinical problem and fine-needle aspiration biopsy (fnab) is its main diagnostic test. recently, it has been shown that some ultrasonographic features are associated to an increased risk of cancer, but a comparison between fnab and ultrasonography (us) or its combination is not available. the aim of this study was to evaluate fnab and us performance, isolated or combined, for cancer diagnosis in thyroid nodules. methods: eighty patients, with palpable solitary thyroid nodules or multinodular goiters, who were to undergo surgery, were selected among 289 patients seen in our clinic between march, 1995 and july, 1997. us and fnab were performed by one of us. us was considered positive for cancer when microcalcifications, absent halo or hypoechogenicity were seen. fnab was considered positive for cancer when it was either suspicious or compatible with malignancy. both methods (fnab and us) were evaluated in parallel combination (positive when fnab or us was positive) and in serial combination (positive when both, fnab and us, were positive). results: sensitivity and specificity of fnab and us for cancer diagnosis in thyroid nodules were, respectively, 87% and 62%, and 81% and 70%. serial combination of fna and us had sensitivity of 69% and specificity of 91%, and parallel combination resulted in sensitivity of 94% and specificity of 52%. conclusion: the us had good accuracy in the evaluation of thyroid nodules, and can help us take some decisions in the clinical practice, supplementary to fna. nevertheless, the quality of the ultrasound examination depends on the experience of the examiner and on the characteristics of the equipment, so new studies are necessary to evaluate these factors to the current usage of ultrasonographic characteristics in the evaluation diagnostic of thyroid nodules.

Abstract: the effects of anionic and cationic diets, associated or not with estradiol injection, and two dry periods (30 days and 60 days), were evaluated in dry matter intake in prepartum and postpartum. the trial was undertaken at dairy research unit of florida university, in gainesville, usa. forty holstein cows were randomly assigned to the treatments in a factorial design: 1. anionic diet, 30 days dry period (ad30) 2. cationic diet, 30 days dry period (cd30), 3. anionic diet, 30 days dry period plus estradiol (ad30e) 4. cationic diet, 30 days dry period plus estradiol (cd30e); 5.anionic diet, 60 days dry period (ad60); 6. cationic diet, 60 days dry period (cd60). after calving, a standard early lactation diet was fed to all cows for 21 days. the cows were under two different range of temperatures: up to 260c, that calved in autumn (season 1) and over 260c, (extreme temperatures) and calved in summer (season 2). ad did not affect prepartum feed intake, however it increases intake when compared to ca in postpartum. the contrasts between treatments showed ad increased postpartum intake in 60 days period (p<0.01) and in 30 days period only when associated with estradiol (p<0.01), suggesting that ad comes the cows faster to feeding, however, ad30 did not affect feed intake, and contrast was not significant (p>0,05).when diets associated with estradiol (ad30e and cd30e) were contrasted with the others, they showed lower intakes, what means that exogenous estrogen reduces postpartum intake. no differences were observed when 30 days period without estradiol injection were compared to sixty days dry period. the days in relation to peripartum showed cubic effects on intake (p<0,01), increasing the intake in the first week postpartum. both feed intake in prepartum and postpartum decreased in season 2, when contrasted to season 1 (p<0,01). in conclusion, however differences between treatments were not detected in prepartum, estradiol injection in prepartum can decrease feed intake.

Abstract: three new cases of human infection with lagochilascaris minor are reported. all the patients were from the state of pará (brazil), living in rural areas or close to the forest. they were admitted to hospitals in the federal district due to the presence of abscesses in the region of the neck, ear, mastoid process and, in two of them, to the involvement also of the central nervous system. microscopic examination of tissue samples taken from the lesions showed sections of eggs and worms - in different evolutive stages - identified as lagochilascaris minor. larvae and adult worms obtained from existing fistulae proved also to be of the same species. the three patients were treated with autihelmintic drugs and surgical excision of the lesions, with good clinical results. in two of them, however, relapsing occurred, suggesting that the drugs do not destroy the worm eggs, in spite of the apparent healing of the lesions.

Jornal Vascular Brasileiro , 2006, DOI: 10.1590/S1677-54492006000100010
Abstract: objectives: chemical sclerotherapy is the most traditional treatment to eliminate telangiectasias. for several decades, it has been carried out in the office, although it has a high index of treatment dropout for being a painful, long and, therefore, little efficient treatment. most of these patients also present insufficient varicose veins, which require phlebectomy and are candidates for surgery. the aim of this paper is to describe the combined treatment including varicose vein surgery and sclerotherapy for telangiectasias at the same procedure. methods: from january 1998 to march 2002, 213 patients (426 lower limbs) with telangiectasias were treated by means of hypertonic glucose infusion during the varicose vein surgery. results: more than 90% of the patients reported high indices of aesthetic satisfaction. the complementary sclerotherapy was necessary in 165 patients to have full aesthetic satisfaction during follow-up. any cases of superficial thrombophlebitis or of deep venous thrombosis were reported. there were no serious complications either. in 10% of cases, small drainage of residual microthrombus was necessary. the index of hyperchromic spots did not exceed 3%. only one patient developed a small ulcer in the back of the foot (0.2%), which spontaneously healed. conclusions: combined treatment including surgery with sclerotherapy for varicose veins and lower extremity telangiectasias is an alternative for patients who desire faster and painless results. multiple session sclerotherapy with hypertonic glucose is a safe and efficient procedure.
