ABSTRACT

Venous thromboembolism (VTE) is a common event in cancer patients and one of the major causes of cancer-associated mortality and a leading cause of morbidity. In recent years, the incidence rates of VTE have notably increased; however, VTE is still commonly underestimated by oncologists. VTE is considered an adverse prognostic factor in cancer patients in all settings. In 2011 the Spanish Society of Medical Oncology (SEOM) first published a clinical guideline of prophylaxis and treatment of VTE in cancer patients. In an effort to incorporate evidence obtained since the original publication, SEOM presents an update of the guideline for thrombosis and cancer in order to improve the prevention and management of VTE.

ABSTRACT

Introducción: La presencia de nódulos tiroideos palpables en la población general, es uno de los signos clínicos tiroideos más frecuentes en la práctica diaria. Objetivos: 1) establecer la prevalencia de las distintas patologías en bocio nodular único palpable y analizar sus características y su relación con los resultados citológicos. 2) analizar la existencia de diferencias regionales en Argentina. Pacientes y Métodos: Estudio prospectivo de 739 pacientes con bocio nodular único palpable evaluados entre el 1/1/2000 y el 31/12/2001 en Centros de Buenos Aires, Bahía Blanca, Mendoza y La Pampa. Se recabaron datos de examen clínico, ecografía tiroidea, TSH, ATPO y citología por punción con aguja fina. (PAAF). Fue utilizado para el análisis estadístico Correlación de Pearson, X2 y Test de Fisher. Resultados: la edad (X ± DS) fue 46,3 ± 14 años, 93,1 % eran de sexo femenino. El 1,6 % tenía historia de radiación en cuello y el 29,9 % antecedentes familiares de patología tiroidea. Hallazgos clínicos: disfagia en el 7,9 %, disfonía 3,5 %, crecimiento nodular en los últimos 6 meses 19,2 %, consistencia dura el 24,7 %, fijeza a estructuras adyacentes 1,5 % y adenopatías en el 3 %. Hallazgos bioquímicos: TSH normal en el 81,2 % y ATPO positivos en el 30,3 % de los casos. Características Ecográficas: nódulos sólidos: 53,1 %, hipoecoicos: 63,8 %, microcalcificaciones 10,3 %, halo incompleto: 15 %, multinodular: 30,5 %, tiroides heterogénea: 60,2 % y adenopatías: 3,8 %. Hallazgos citológicos: En el 86,8 % de los casos fue necesario solo una punción para llegar al diagnóstico. Insatisfactorio (excluyendo quiste): 3,2 %: benignos: 77,3 %; sospechosos: 12,6 % y cáncer: 7 % (42 papilar, 2 medular y 3 sin especificar). Una correlación significativa (p<0,02) fue observada entre citología maligna y crecimiento rápido, dureza, fijeza a estructuras vecinas, nódulo sólido, halo incompleto y adenopatías aunque estos parámetros son más frecuentes en números absolutos en nódulos benignos. La mayoría de las cirugías fueron indicadas en base al hallazgo citológico. El diagnóstico histológico de los 96 pacientes que fueron operados mostró 51 carcinomas, de los cuales solo dos tenían citología benigna y 31 adenomas. Conclusión: Los nódulos palpables únicos fueron más frecuentes en mujeres eutiroideas en la edad media de la vida. Un tercio tenía historia familiar de patología tiroidea, similar al porcentaje hallado de ATPO positivos. Por ecografía los nódulos fueron predominantemente sólidos, hipoecoicos, únicos con resto de la glándula tiroides heterogénea. La PAAF fue predominantemente benigna. El crecimiento rápido, la dureza, la fijeza a estructuras adyacentes, el halo incompleto y la presencia de adenopatías fueron relacionados con malignidad, pero la benignidad fue más frecuente. En la mayoría de los pacientes la cirugía fue recomendada por los hallazgos citológicos. Nuestros resultados son similares a los reportados en otras áreas geográficas.


Introduction: the presence of palpable thyroid nodules in the general population is one of the most common clinical signs of thyroid disease in daily practice. Objectives: 1) To assess the prevalence of pathologies, clinical and cytological findings of single palpable thyroid nodules (SPTN) in Argentina. 2) Analyze the regional differences in Argentina. Methods: Prospective study of 739 patients with STPN were evaluated at centres in Buenos Aires, Bahía Blanca, Mendoza, and La Pampa between 1/1/00 and 12/31/01. Clinical examination, thyroid ultrasound scan (US), TSH, TPOAb and fine needle aspirations (FNA) were performed. Statistics: Pearson Correlation, X2 & Fisher Tests. Results: Age (X ± SD) 46 ± 14ys: 93.1 % were women. Previous history of neck radiation & familial thyroid disease were found in 1.6 and 29.9 % respectively. Clinical findings: dysphagia: 7.9 %; dysphonia: 3.5%; nodule growth: 19.2 %; hard consistence: 24.7 %; fixation to adjacent structure: 1.5 % and lymphadenopathies (ADP): 3 %. Biochemical findings: TSH was normal in 81.2 % & TPOAb+ in 30.3 %. US features: solid: 53.1 %; hypoechoic: 63.8 %; microcalcifications: 10.3 %; incomplete halo: 15 %; more than 1 nodule: 30.5 %; thyroid heterogeneity: 60.2 % and ADP: 3.8 %. Cytology: Only 1 FNA was needed in 86.8%. Unsatisfactory (excluding cysts): 3.2 %; benign: 77.2%; suspicious: 12.6 % and cancer: 7 % (42 papillary, 2 medullary and 3 non specified). A significant correlation (p<0.02) was established between malignant nodules and rapid growth, hard, fixed, solid nodule, incomplete halo and ADP, though these parameters were more frequent (in absolute number) in benign nodules. Surgery was mainly indicated based on FNA results. Histological diagnosis of 96 patients who underwent surgery showed 51 carcinomas, of which only 2 were cytologically benign and 31 adenomas. Conclusion: Palpable single nodules were more frequent in middle aged euthyroid women. One third had familial thyroid pathology, similar to the presence of TPOAb. On US, nodules were predominantly solid, hypoechoic, single with heterogeneous thyroid gland. FNA was predominantly benign. Rapid growth, hard, fixed, solid nodule, incomplete halo and ADP were associated with malignancy, but benignity was more common. In most of the patients surgery was recommended based on cytological findings. Our results are similar to those reported in other geographic areas.

ABSTRACT

Neurocysticercosis is a helminthiasis of the central nervous system produced by the encysted larvae of the pork tapeworm Taenia solium. We report 4 cases of neurocysticercosis observed in immigrants from endemic areas (India and Latin America). Three of the patients were diagnosed because of new onset of seizures, all of the no received anthelmintic therapy with favourable outcome. The fourth case was a form known as racemose cysticercosis. She was admitted because of CNS sensorial symptoms with later development of severe intracranial hypertension that required surgical treatment. All the cases had a positive result in the ELISA test for cysticercosis. In only one patient chronic epilepsy persisted thus needing long-term anticonvulsant therapy as a sequelae. Our report helps to familiarize clinicians with the characteristic radiological findings from cysticercosis and em s the fact that epidemiological suspicion and serological data are usually enough to get the diagnosis and avoid unnecessary probes.
