RESUMO Introdução: a videocirurgia no Brasil iniciou em 1990 com a realização da colecistectomia laparoscópica, sendo incluída pelo sistema público de saúde em 2008. Avaliamos a situação atual do emprego desta tecnologia no Sistema Único de Saúde (SUS). Métodos: de 2013 a 2019, 1.406.654 pacientes registrados no Departamento de Informática do SUS (DATASUS) foram analisados para calcular a taxa de colecistectomias laparoscópicas (CL) em relação a colecistectomias abertas (CA). Avaliaram-se características dos pacientes, apresentação da doença e mortalidade pós-operatória. Resultados: a taxa de CL atingiu 41,5%, com crescimento de 68%, sem ocorrer diminuição do número absoluto de CA. Já em Hospitais Universitários (HUs) a taxa de CL chegou a 91,96%. A técnica aberta em urgências esteve mais associada a pacientes masculinos, com 60 anos ou mais, à internação prolongada e em UTI. Aqueles submetidos à CL estiveram menos predispostos à morte pós-operatória, tanto em caráter eletivo (OR 0,49; IC 95% 0,42 - 0,56; NNT = 20) como na urgência (OR 0,23; IC 95% 0,20 - 0,25; NNT ≅ 1), conferindo efeito protetor. Conclusão: apesar do aumento da indicação da CL, a cirurgia aberta durante os anos estudados se manteve estável e a técnica mais utilizada no sistema público de saúde do Brasil. A efetividade de políticas de saúde pública para abreviar a completa implementação da videocirurgia no SUS necessita ser investigada em estudos epidemiológicos futuros, assim como seu impacto na morbimortalidade pós-operatória.

ABSTRACT Objective: videosurgery in Brazil started in 1990 with the performance of laparoscopic cholecystectomy, being included by the public health system in 2008. We evaluated the current situation of the use of this technology in the Unified Health System (SUS - Sistema Único de Saúde). Methods: from 2013 to 2019, 1,406,654 patients registered at the SUS Informatics Department (DATASUS) were analyzed to calculate the rate of laparoscopic cholecystectomies (LC) in relation to open cholecystectomies (OC). Patient characteristics, disease presentation and postoperative mortality were evaluated. Results: the LC rate reached 41.5% (growth of 68%) with no decrease in the absolute number of OC. In University Hospitals (UH), the LC rate reached 91.96%. The open technique in emergencies was more associated with male patients, aged 60 years or older, with prolonged hospitalization and in the ICU. Those undergoing LC were less predisposed to postoperative death, both electively (OR 0.49; 95% CI 0.42 - 0.56; NNT=20) and urgently (OR 0.23; 95% CI 0.20 - 0.25; NNT ≅1), providing a protective effect. Conclusion: despite the increase in the indication of LC, the open technique during the years studied remained stable and the most used in the public health system in Brazil. The effectiveness of public health policies to shorten the complete implementation of videosurgery in SUS needs to be investigated in future epidemiological studies, as well as its impact on postoperative morbidity and mortality.

Abstract: En | Text: En | PDF: En

ABSTRACT Hypopituitarism is a disorder characterized by insufficient secretion of one or more pituitary hormones. New etiologies of hypopituitarism have been recently described, including head trauma, cerebral hemorrhage, and drug-induced hypophysitis. The investigation of patients with these new disorders, in addition to advances in diagnosis and treatment of hypopituitarism, has increased the prevalence of this condition. Pituitary hormone deficiencies can induce significant clinical changes with consequent increased morbidity and mortality rates, while hormone replacement based on current guidelines protects these patients. In this review, we will first discuss the different etiologies of hypopituitarism and then address one by one the clinical aspects, diagnostic evaluation, and therapeutic options for deficiencies of TSH, ACTH, gonadotropin, and GH. Finally, we will detail the hormonal interactions that occur during replacement of pituitary hormones.

ABSTRACT Objective Investigate the therapeutic response of acromegaly patients to pegvisomant (PEGV) in a real-life, Brazilian multicenter study. Subjects and methods Characteristics of acromegaly patients treated with PEGV were reviewed at diagnosis, just before and during treatment. All patients with at least two IGF-I measurements on PEGV were included. Efficacy was defined as any normal IGF-I measurement during treatment. Safety data were reviewed. Predictors of response were determined by comparing controlled versus uncontrolled patients. Results 109 patients [61 women; median age at diagnosis 34 years; 95.3% macroadenomas] from 10 Brazilian centers were studied. Previous treatment included surgery (89%), radiotherapy (34%), somatostatin receptor ligands (99%), and cabergoline (67%). Before PEGV, median levels of GH, IGF-I and IGF-I % of upper limit of normal were 4.3 µg/L, 613 ng/mL, and 209%, respectively. Pre-diabetes/diabetes was present in 48.6% and tumor remnant in 71% of patients. Initial dose was 10 mg/day in all except 4 cases, maximum dose was 30 mg/day, and median exposure time was 30.5 months. PEGV was used as monotherapy in 11% of cases. Normal IGF-I levels was obtained in 74.1% of patients. Glycemic control improved in 56.6% of patients with pre-diabetes/diabetes. Exposure time, pre-treatment GH and IGF-I levels were predictors of response. Tumor enlargement occurred in 6.5% and elevation of liver enzymes in 9.2%. PEGV was discontinued in 6 patients and 3 deaths unrelated to the drug were reported. Conclusions In a real-life scenario, PEGV is a highly effective and safe treatment for acromegaly patients not controlled with other therapies.

Abstract: En | Text: En | PDF: En

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called “hook effect”. Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

Abstract: En | Text: En | PDF: En

ABSTRACT The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal pituitary surgery is the main treatment option for the majority of cases, even in macroadenomas with low probability of remission. In cases of surgical failure, another subsequent pituitary surgery might be indicated in cases with persistent tumor imaging at post surgical magnetic resonance imaging (MRI) and/or pathology analysis of adrenocorticotropic hormone-positive (ACTH+) positive pituitary adenoma in the first procedure. Medical treatment, radiotherapy and adrenalectomy are the other options when transsphenoidal pituitary surgery fails. There are several options of medical treatment, although cabergoline and ketoconazole are the most commonly used alone or in combination. Novel treatments are also addressed in this review. Different therapeutic approaches are frequently needed on an individual basis, both before and, particularly, after surgery, and they should be individualized. The objective of the present review is to provide the necessary information to achieve a more effective treatment for CD. It is recommended that patients with CD be followed at tertiary care centers with experience in treating this condition.

Abstract: En | Text: En | PDF: En

ABSTRACT Although it is a rare condition, the accurate diagnosis and treatment of Cushing’s disease is important due to its higher morbidity and mortality compared to the general population, which is attributed to cardiovascular diseases, diabetes mellitus and infections. Screening for hypercortisolism is recommended for patients who present multiple and progressive clinical signs and symptoms, especially those who are considered to be more specific to Cushing’s syndrome, abnormal findings relative to age (e.g., spinal osteoporosis and high blood pressure in young patients), weight gain associated with reduced growth rate in the pediatric population and for those with adrenal incidentalomas. Routine screening is not recommended for other groups of patients, such as those with obesity or diabetes mellitus. Magnetic resonance imaging (MRI) of the pituitary, the corticotropin-releasing hormone (CRH) test and the high-dose dexamethasone suppression test are the main tests for the differential diagnosis of ACTH-dependent Cushing’s syndrome. Bilateral and simultaneous petrosal sinus sampling is the gold standard method and is performed when the triad of initial tests is inconclusive, doubtful or conflicting. The aim of this article is to provide information on the early detection and establishment of a proper diagnosis of Cushing’s disease, recommending follow-up of these patients at experienced referral centers.

Abstract: En | Text: En | PDF: En

OBJECTIVE: Studies suggest an association between vitamin D deficiency and morbidity/mortality in critically ill patients. Several issues remain unexplained, including which vitamin D levels are related to morbidity and mortality and the relevance of vitamin D kinetics to clinical outcomes. We conducted this study to address the association of baseline vitamin D levels and vitamin D kinetics with morbidity and mortality in critically ill patients. METHOD: In 135 intensive care unit (ICU) patients, vitamin D was prospectively measured on admission and weekly until discharge from the ICU. The following outcomes of interest were analyzed: 28-day mortality, mechanical ventilation, length of stay, infection rate, and culture positivity. RESULTS: Mortality rates were higher among patients with vitamin D levels <12 ng/mL (versus vitamin D levels >12 ng/mL) (32.2% vs. 13.2%), with an adjusted relative risk of 2.2 (95% CI 1.07-4.54; p< 0.05). There were no differences in the length of stay, ventilation requirements, infection rate, or culture positivity. CONCLUSIONS: This study suggests that low vitamin D levels on ICU admission are an independent risk factor for mortality in critically ill patients. Low vitamin D levels at ICU admission may have a causal relationship with mortality and may serve as an indicator for vitamin D replacement among critically ill patients.

OBJETIVO: Avaliar os níveis séricos dos principais fatores que regulam a ativação da zona glomerulosa e a produção de aldosterona em pacientes com choque séptico, assim como sua resposta ao teste de cortrosina em alta dose (250 µg). SUJEITOS E MÉTODOS: Em 27 portadores de choque séptico, foram aferidos níveis basais de aldosterona, cortisol, ACTH, renina, sódio, potássio e lactato, bem como realizado teste de cortrosina. RESULTADOS: Renina se correlacionou com níveis basais de aldosterona e sua variação após teste de cortrosina. Cortisol basal e sua variação não se correlacionaram com ACTH. Apenas três pacientes apresentaram disfunção concomitante da secreção de aldosterona e cortisol. CONCLUSÕES: Ativação das zonas fasciculada e glomerulosa são independentes. Secreção de aldosterona é dependente da integridade do sistema renina-angiotensina-aldosterona, enquanto secreção de cortisol não parece predominantemente dependente do eixo hipotálamo-hipófise-adrenal. Esses resultados sugerem que a ativação da adrenal em pacientes críticos ocorre por múltiplos mecanismos.

OBJECTIVE: To assess serum levels of the main factors that regulate the activation of the zona glomerulosa and aldosterone production in patients with septic shock, as well as their response to a high-dose (250 µg) adrenocorticotropic hormone (ACTH) stimulation test. SUBJECTS AND METHODS: In 27 patients with septic shock, baseline levels of aldosterone, cortisol, ACTH, renin, sodium, potassium, and lactate were measured, followed by a cortrosyn test. RESULTS: Renin correlated with baseline aldosterone and its variation after cortrosyn stimulation. Baseline cortisol and its variation did not correlate with ACTH. Only three patients had concomitant dysfunction of aldosterone and cortisol secretion. CONCLUSIONS: Activation of the zona glomerulosa and zona fasciculata are independent. Aldosterone secretion is dependent on the integrity of the renin-angiotensin-aldosterone system, whereas cortisol secretion does not appear to depend predominantly on the hypothalamic-pituitary-adrenal axis. These results suggest that activation of the adrenal gland in critically ill patients occurs by multiple mechanisms.

OBJETIVOS: Avaliar a presença de diabetes melito (DM) em uma coorte de acromegálicos. MÉTODOS: Este é um estudo transversal. RESULTADOS: Cinquenta e oito pacientes acromegálicos foram analisados. Apenas 29% preencheram critérios de cura e 27% estavam com a doença controlada. Vinte e dois pacientes (38%) apresentaram DM, HbA1c 7,34 ± 2,2%. Destes, 18 não preencheram critérios de cura. Pacientes com DM foram mais frequentemente hipertensos [16/22 (73%) vs. 17/36 (46%), p = 0,04] e usavam mais estatina [14/22 (64%) vs.8/36 (21%), p = 0,004]. Após regressão múltipla, hipertensão foi associada a DM [razão de chances (RC): 9,28 (95% CI: 1,59 - 54,00), p = 0,01], e acromegalia curada/controlada foi fator protetor para presença de diabetes [OR: 0,17 (95% CI: 0,03-0,78), p = 0,02]. CONCLUSÕES: A presença de DM esteve associada com acromegalia ativa e com a presença de hipertensão. No entanto, os níveis absolutos de GH e IGF-1 não diferiram entre aqueles com e sem diabetes.

OBJECTIVES: To evaluate the presence of diabetes mellitus (DM) in a cohort of patients with acromegaly. METHODS: This was a cross sectional study. RESULTS: Fifty-eight acromegalic patients were assessed. Only 29% met the criteria for cure, and 27% had the disease controlled. Twenty-two had DM; HbA1c was equal to 7.34 ± 2.2%. Most of the diabetic patients (18 out of 22, 82%) did not meet criteria for cure. They were more often hypertensive [16/22 (73%) vs. 17/36 (46%), p = 0.04], and used statins more frequently [14/22 (64%) vs. 8/36 (21%), p = 0.004]. After regression analysis, hypertension was associated with diabetes [odds ratio (OR): 9.28 (95% CI: 1.59 - 54.00), p = 0.01], and cured/ controlled acromegaly was associated with protection against the presence of diabetes [OR: 0.17 (95% CI: 0.03 - 0.78), p = 0.02]. CONCLUSIONS: The presence of DM was associated with active acromegaly and presence of hypertension. However, absolute levels of GH and IGF-1 did not differ between patients with and without diabetes.

INTRODUÇÃO: Existem várias complicações no sistema cardiovascular causadas pela acromegalia, especialmente a hipertensão. OBJETIVOS: Avaliar as características da hipertensão em pacientes com acromegalia curada/controlada e com doença ativa. PACIENTES E MÉTODOS: Estudo transversal com 44 pacientes com acromegalia seguidos em nosso serviço. Eles foram submetidos a avaliação clínica, exames laboratoriais e ecocardiograma. Pacientes com doença curada/controlada foram avaliados como um grupo único e os indivíduos com doença ativa como outro grupo. RESULTADOS: Quarenta e sete por cento dos pacientes apresentaram acromegalia ativa. Esses indivíduos foram mais jovens e apresentaram níveis mais baixos de pressão arterial que os indivíduos com doença controlada/curada. A hipertensão foi detectada em 50% da amostra. Indivíduos com doença ativa mostraram uma correlação positiva entre os níveis de IGF-1 e os níveis de pressão arterial sistólica e de pressão arterial diastólica (r = 0,48, p = 0,03; e r = 0,42, p = 0,07, respectivamente) e também apresentaram uma correlação positiva entre IGF-1 e excreção urinária de albumina (EUA). Em pacientes com doença ativa, o IGF-1 foi um preditor da pressão arterial sistólica, embora não tenha sido independente da taxa de EUA. Para indivíduos com doença curada/controlada, a circunferência da cintura e os triglicérides foram os preditores associados aos níveis de pressão arterial sistólica e diastólica. CONCLUSÕES: Nossos resultados sugerem que os níveis pressóricos em pacientes com acromegalia ativa dependem do excesso de GH. No entanto, uma vez que a doença torna-se controlada e os níveis de IGF-1 reduzem, os níveis de pressão arterial dependerão de outros fatores de risco cardiovasculares.

INTRODUCTION: There are several complications of the cardiovascular system caused by acromegaly, especially hypertension. OBJECTIVES: To evaluate hypertension characteristics in patients with cured/controlled acromegaly and with the active disease. PATIENTS AND METHODS: Cross-sectional study of the follow-up of forty-four patients with acromegaly submitted to clinical evaluation, laboratory tests and cardiac ultrasound. Patients with cured and controlled disease were evaluated as one group, and individuals with active disease as second one. RESULTS: Forty-seven percent of the patients had active acromegaly, and these patients were younger and had lower blood pressure levels than subjects with controlled/cured disease. Hypertension was detected in 50% of patients. Subjects with active disease showed a positive correlation between IGF-1 and systolic and diastolic blood pressure levels (r = 0.48, p = 0.03; and r = 0.42, p = 0.07, respectively), and a positive correlation between IGF-1 and urinary albumin excretion (UAE) rates. In patients with active disease, IGF-1 was a predictor of systolic blood pressure, although it was not independent of UAE rate. For individuals with cured/controlled disease, waist circumference and triglycerides were the predictors associated with systolic and diastolic blood pressure. CONCLUSIONS: Our findings suggest that blood pressure levels in patients with active acromegaly are very similar, and depend on excess GH. However, once the disease becomes controlled and IGF-1 levels decrease, their blood pressure levels will depend on the other cardiovascular risk factors.

A acromegalia é uma doença associada à elevada morbidade e à redução da expectativa de vida. Em virtude do seu caráter insidioso e do seu não reconhecimento, o diagnóstico é frequentemente realizado com atraso, o que, associado às complicações relacionadas ao excesso do GH/IGF-I, determina elevada morbimortalidade. No entanto, um diagnóstico precoce e um tratamento efetivo minimizam a morbidade e normalizam a taxa de mortalidade. Nesta publicação, o objetivo do Departamento de Neuroendocrinologia da Sociedade Brasileira de Endocrinologia e Metabologia é divulgar quando suspeitar clinicamente da acromegalia e como diagnosticá-la. Além disso, discute-se a maneira mais eficaz e segura de realizar o tratamento da acromegalia, enfatizando que este deve ser realizado em centros de referência. Assim, com base em dados publicados em periódicos de nível científico reconhecido e na experiência dos autores, são apresentadas as recomendações para o diagnóstico e tratamento da doença.

Acromegaly is a disease associated with increased morbidity and reduced life expectancy. Because of its insidious character and its non-recognition, the diagnosis is often made with delay, which, along with the complications related to GH/IGF-I excess, determines high morbidity and mortality. However, an early diagnosis and an effective treatment reduce the morbidity and normalize the mortality rate. In this publication, the goal of Neuroendocrinology Department from Brazilian Society of Endocrinology and Metabolism is to disclose which clinical set should arouse the suspicious of acromegaly and how to diagnose it. Furthermore, we discuss the most effective and safe approach to perform the treatment of acromegaly, emphasizing that it must be carried out in reference centers. Therefore, based on data published in journals with recognized scientific level and authors' experience, recommendations are presented for diagnosis and treatment of the disease.

OBJETIVO: Verificar em que medida o Recordatório Alimentar de 24 horas como instrumento de avaliação do consumo alimentar contribui para a avaliação de parâmetros biológicos envolvidos no metabolismo de cálcio, fósforo e vitamina D em crianças e adolescentes de baixa estatura. MÉTODOS: Foram avaliados 59 crianças e adolescentes com baixa estatura do Ambulatório de Baixa Estatura do Serviço de Endocrinologia do Hospital das Clínicas de Porto Alegre. Causas orgânicas, genéticas e endócrinas de baixa estatura foram excluídas da avaliação. Foram dosados cálcio, fósforo, creatinina, vitamina D, paratormônio fosfatase alcalina no soro e cálcio, fósforo, creatinina e sódio em urina de Recordatório Alimentar de 24h foi empregado para estimar o consumo dietético. RESULTADOS: Foi constatada ingestão reduzida de cálcio e vitamina D, em relação ao recomendado para idade e sexo. Verificou-se correlação negativa entre paratormônio e vitamina D dietética (r= -0,46; p<0,01), consumo de cálcio (r= -0,41; p<0,001), calciúria (r= -0,41; p<0,001) e o índice de excreção de cálcio na urina de 24 horas (r= -0,36; p<0,01). CONCLUSÃO: Quando comparados os resultados do Recordatório Alimentar de 24 horas com seus parâmetros bioquímicos, este instrumento pareceu adequado na estimativa do consumo dietético de micronutrientes de crianças e adolescentes.

OBJECTIVE: The objective of this study was to verify the extent to which the 24 hour recall, used as a tool to assess dietary intake, contributes to the assessment of biological parameters involved in the metabolism of calcium, phosphorus and vitamin D in stunted children and adolescents. METHODS: A total of 59 stunted children and adolescents seen at the outpatient clinic that specializes in stunting of the Endocrinology Service of Hospital das Clínicas in Porto Alegre, were assessed. Organic, genetic and endocrine causes of stunting were excluded from the assessment. Serum calcium, phosphorus, creatinine, vitamin D, parathormone and alkaline phosphatase and urine calcium, phosphorus, creatinine and sodium were measured. The 24 hour recall was used to determine dietary intake of these nutrients. RESULTS: Calcium and vitamin D intakes were low according to the values recommended for the two genders and studied age groups. There was a negative correlation between parathormone and dietary vitamin D (r= -0.46; p<0.01), calcium intake (r= -0.41; p<0.001), urine calcium (r= -0.41; p<0.001) and the calcium excretion index in the 24 hour urine (r= -0.36; p<0.01). CONCLUSION: When the 24-hour recall results were compared with their biochemical parameters, this instrument seemed to estimate the dietary micronutrient intakes of children and adolescents correctly.

A acromegalia acarreta uma série de distúrbios ao sistema cardiovascular, decorrentes da exposição crônica a níveis elevados de GH e IGF-1. Estes distúrbios são os principais responsáveis pelo aumento da mortalidade de acromegálicos. Entre as várias formas de acometimento cardiovascular, destaca-se a miocardiopatia acromegálica, entidade caracterizada, inicialmente, pelo estado hiperdinâmico, seguido de hipertrofia ventricular esquerda concêntrica e disfunção diastólica por déficit de relaxamento, culminando com disfunção sistólica e, por vezes, insuficiência cardíaca franca. Além disso, são também relevantes as arritmias, as valvulopatias, sobretudo mitral e aórtica, a cardiopatia isquêmica, a hipertensão e os distúrbios dos metabolismos glicêmico e lipídico. Nesta revisão são abordados os principais aspectos clínicos e prognósticos destas entidades, os efeitos do tratamento da acromegalia sobre elas e as repercussões correspondentes sobre a sobrevida dos pacientes.

Acromegaly causes a number of disorders in the cardiovascular system, resulting from chronic exposure to high levels of GH and IGF-1. Such disorders are the main responsible for increased mortality rates among acromegalic patients. Among several forms of cardiovascular impairment is acromegalic cardiomyopathy, an entity that is initially characterized by a hyperdynamic state, followed by concentric left ventricular hypertrophy and diastolic dysfunction due to relaxation deficit, culminating in systolic dysfunction and sometimes heart failure. In addition, arrhythmias and heart valve diseases are also relevant, especially mitral and aortic, ischemic heart disease, hypertension, and glucose and lipid metabolism disorders. This review approaches the main clinical and prognostic aspects of these entities, the effects of acromegaly treatment on them, and the respective consequences on patient survival.

Os nódulos de tireóide são um problema clínico comum e a punção aspirativa por agulha fina (PAAF) é o principal exame utilizado para seu diagnóstico diferencial. Recentemente, foi demonstrado que algumas características ultra-sonográficas dos nódulos estão associadas a um maior risco de câncer. Entretanto, não 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 combinação no diagnóstico de câncer em nódulos de tireóide. MÉTODOS: Oitenta pacientes com nódulos únicos ou dominantes, com indicação cirúrgica, foram selecionados dentre 289 pacientes com nódulos tireoidianos atendidos entre março 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 câncer. A US foi considerada positiva quando os nódulos apresentavam pelo menos um dos seguintes achados: microcalcificações, 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 presença de malignidade). RESULTADOS: A sensibilidade e a especificidade da PAAF na detecção do câncer em nódulos de tireóide foram, respectivamente, 87% e 62%, e a sensibilidade e a especificidade da US foram, respectivamente, 81% e 70%. A combinação em série dos dois exames (PAAF e US) resultou em sensibilidade de 69% e especificidade de 91%, e a combinação em paralelo (PAAF ou US) apresentou sensibilidade de 94% e especificidade de 52%. CONCLUSÃO: A US pode ser útil na avaliação dos nódulos de tireóide, alternativamente ou em combinações com a PAAF. Como o resultado da US depende da experiência do operador e das características do equipamento, são necessários estudos em diferentes centros para o seu uso na prática clínica.

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.
