ABSTRACT Objective: A primary medical relevance of thyroid nodules consists of excluding thyroid cancer, present in approximately 5% of all thyroid nodules. Fine-needle aspiration biopsy (FNAB) has a paramount role in distinguishing benign from malignant thyroid nodules due to its availability and diagnostic performance. Nevertheless, intraoperative frozen section (iFS) is still advocated as a valuable tool for surgery planning, especially for indeterminate nodules. Subjects and methods: To compare the FNAB and iFS performances in thyroid cancer diagnosis among nodules in Bethesda Categories (BC) I to VI. The performance of FNAB and iFS tests were calculated using final histopathology results as the gold standard. Results: In total, 316 patients were included in the analysis. Both FNAB and iFS data were available for 272 patients (86.1%). The overall malignancy rate was 30.4%% (n = 96). The FNAB sensitivity, specificity, and accuracy for benign (BC II) and malignant (BC V and VI) were 89.5%, 97.1%, and 94.1%, respectively. For all nodules evaluated, the iFS sensitivity, specificity, and accuracy were 80.9%, 100%, and 94.9%, respectively. For indeterminate nodules and follicular lesions (BC III and IV), the iFS sensitivity, specificity, and accuracy were 25%, 100%, and 88.7%, respectively. For BC I nodules, iFS had 95.2% of accuracy. Conclusion: Our results do not support routine iFS for indeterminate nodules or follicular neoplasms (BC III and IV) due to its low sensitivity. In these categories, iFS is not sufficiently accurate to guide the intraoperative management of thyroidectomies. iFS for BC I nodules could be an option and should be specifically investigated

Resumen Introducción: La elastografía por ondas de corte (SWE) ha demostrado ser predictiva de malignidad en nódulos tiroideos. Objetivo: Determinar mediante SWE, el punto de corte de la rigidez con mayor especificidad y sensibilidad para detectar nódulos tiroideos que requieren cirugía. Métodos: Estudio transversal de pacientes con nódulos tiroideos evaluados ultrasonográficamente en un periodo de tres años; se empleó la clasificación TI-RADS y mediante SWE se determinó la rigidez de los nódulos. Con el sistema Bethesda se clasificaron las muestras histopatológicas y mediante curva ROC se obtuvo el punto de corte de la rigidez con mayor especificidad y sensibilidad. Resultados: 41 % de los nódulos fue TI-RADS 5 y 59 %, TI-RADS 1-4. En los TI-RADS 5, la mediana de rigidez de los nódulos con categoría IV-VI del sistema Bethesda fue de 35.9 kPa y en los nódulos con TI-RADS 1-4, 21.6 kPa. En los nódulos TI-RADS 5, la rigidez > 32.5 kPa tuvo especificidad de 75 % y sensibilidad de 57 % para detectar los que requieren cirugía; en los TI-RADS 1-4, el valor de corte de 21.5 kPa tuvo especificidad de 63 % y sensibilidad de 51 %. Conclusión: La rigidez determinada por SWE es útil para detectar nódulos que requerirán exploración quirúrgica.

Abstract Introduction: Shear-wave elastography (SWE) has been shown to be predictive of malignancy in thyroid nodules. Objective: To determine, by SWE, the stiffness cutoff point with the highest specificity and sensitivity to detect thyroid nodules that require surgery. Methods: Cross-sectional study of ultrasonographically-evaluated patients for thyroid nodules over a period of three years; the TI-RADS classification system was used, and nodule stiffness was determined by SWE. Histopathological specimens were classified using the Bethesda system, and the stiffness cutoff point with the highest specificity and sensitivity was obtained using ROC curves. Results: Forty-one percent of the nodules were classified as TI-RADS 5, and 59 %, as TI-RADS 1-4. In TI-RADS 5 nodules, median stiffness of those in Bethesda system IV-VI categories was 35.9 kPa; in nodules with TI-RADS 1-4, 21.6 kPa. In TI-RADS 5 nodules, a cutoff point > 32.5 kPa had a specificity of 75 % and sensitivity of 57 % to detect those requiring surgery; in TI-RADS 1 to 4 nodules, a cutoff point of 21.5 kPa had a specificity of 63 % and sensitivity of 51 %. Conclusion: SWE-determined stiffness is useful to detect nodules that require surgical evaluation.

Abstract Introduction: Laryngeal lesions are usually evaluated by microlaryngoscopy/direct laryngoscopy under anaesthesia for disease mapping and tissue diagnosis. However patients with anticipated airway compromise due to laryngeal mass may require either a protective tracheotomy or emergency tracheotomy to secure the airway. To minimise risk of unplanned tracheotomy and expedite the diagnosis we performed ultrasound-guided transcutaneous fine needle aspiration cytology. Objective: To evaluate the feasibility and performance of ultrasound-guided transcutaneous fine needle aspiration cytology of suspicious/recurrent laryngo-hypopharyngeal masses. Methods: Fine needle aspiration cytology was performed under ultrasound guidance. Twenty- four patients were recruited, of which 17 had a pure laryngeal lesion; 6 patients had laryngo-pharyngeal, and one patient had a base tongue lesion with supra-glottis extension. Results: Out of 24 patients, 21 had positive cytology for squamous cell carcinoma, 2 patients had non-diagnostic cytology (atypical cells) and the other had inadequate tissue for definitive diagnosis. Patients with negative and inconclusive cytology underwent direct laryngoscopy biopsy, which was positive for squamous malignancy. All patients tolerated the procedure well and no adverse events were noted. Conclusion: Although direct laryngoscopy remains the standard of care in evaluation of laryngo-hypopharyngeal lesions, this pilot study has shown that ultrasound-guided transcutaneous fine needle aspiration cytology was feasible as an out-patient procedure, employing safe and sensitive technique enabling rapid diagnosis and avoiding the need for direct laryngoscopy under GA for tissue diagnosis.

Resumo Introdução: As lesões laríngeas são geralmente avaliadas por microlaringoscopia/laringoscopia direta sob anestesia para mapeamento da doença e diagnóstico tecidual. No entanto, em pacientes com comprometimento prévio das vias aéreas devido à lesão laríngea, pode ser necessária uma traqueostomia protetora ou traqueostomia de emergência para assegurar as vias aéreas. Para minimizar o risco de uma traqueostomia não planejada e facilitar o diagnóstico, realizamos punção aspirativa por agulha fina guiada por ultrassonografia transcutânea. Objetivo: Avaliar a viabilidade e o desempenho da punção aspirativa por agulha fina guiada por ultrassonografia transcutânea em lesões laríngeo-hipofaríngeas suspeitas/recorrentes. Método: A punção aspirativa por agulha fina foi realizada sob orientação ultrassonográfica. Foram recrutados 24 pacientes, 17 com lesão laríngea apenas, 6 com lesão laríngeo-faríngea e um com lesão na base da língua com extensão supraglótica. Resultados: Dos 24 pacientes, 21 apresentaram citologia positiva para carcinoma espinocelular, 2 citologia não diagnóstica (células atípicas) e o outro tecido inadequado para o diagnóstico definitivo. Os pacientes com citologia negativa e inconclusiva foram submetidos à biópsia através de laringoscopia direta, que foi positiva para lesão maligna espinocelular. Todos os pacientes toleraram bem o procedimento e nenhum evento adverso foi observado. Conclusão: Embora a laringoscopia direta continue a ser o padrão de cuidado na avaliação das lesões laríngeo-hipofaríngeas, este estudo piloto demonstrou que a punção aspirativa por agulha fina guiada por ultrassonografia transcutânea é uma técnica viável, ambulatorial, segura e sensível, permite rápido diagnóstico e evita a necessidade de laringoscopia direta sob anestesia geral para diagnóstico tecidual.

ABSTRACT Introduction: Nodular thyroid disease is a reason for medical consultation, the surgical decision is marked by the suspicion of malignancy, an increase in size, the presence of a compression symptoms, and even aesthetic reasons. Objective: To describe the clinical and surgical characteristics of patients with thyroid disease, operated at the "Comandante Pinares" hospital. Methods: A descriptive, ambispective study of patients undergoing thyroid surgery at the "Comandante Pinares" Hospital was performed in the period from January 2014 to December 2018. A sample was taken of 85 patients who met the inclusion criteria. Data was obtained from medical records in a form designed for research. Demographic, epidemiological, clinical, paraclinical and surgical variables were measured using statistical methods for quantitative and qualitative variables. Results: Surgical thyroid conditions were more frequent in females, between 50 and 59 years of age, with benign nodules prevailing. The most frequent clinical form of presentation was solid nodular, and malignant nodules appeared mainly in tumors smaller than 2 cm. The definitive diagnosis according to the results of the paraffin biopsy showed that the majority of the lesions were benign, with a predominance of nodular goiter and fine needle aspiration biopsy. The most frequent result was negative. The most widely used surgical technique was Total Thyroidectomy at one time. Most of the patients did not present complications. Conclusions: The treatment of surgical thyroid conditions shows satisfactory results, predominating the conditions in the female sex, of benign etiology(AU)

OBJECTIVE: Fine-needle aspiration cytology is the risk stratification tool for thyroid nodules, and ultrasound elastography is not routinely used for the differential diagnosis of thyroid cancer. The current study aimed to compare the diagnostic parameters of ultrasound elastography and fine-needle aspiration cytology, using surgical pathology as the reference standard. METHODS: In total, 205 patients with abnormal thyroid function test results underwent ultrasound-guided fine-needle aspiration cytology on the basis of the American College of Radiology Thyroid Imaging-Reporting and Data System classification and strain ultrasound elastography according to the ASTERIA criteria. Histopathological examination of the surgical specimens was performed according to the 2017 World Health Organization classification system. Moreover, a beneficial score analysis for each modality was conducted. RESULTS: Of 265 nodules, 212 measured ≥1 cm. The strain index value increased from benign to malignant nodules, and the presence of autoimmune thyroid diseases did not affect the results (p>0.05 for all categories). The sensitivities of histopathological examination, ultrasound elastography, and fine-needle aspiration cytology for detection of nodules measuring ≥1 cm were 1, 1, and 0.97, respectively. The working area for detecting nodule(s) in a single image was similar between strain ultrasound elastography and fine-needle aspiration cytology for highly and moderately suspicious nodules. However, for mildly suspicious, unsuspicious, and benign nodules, the working area for detecting nodule(s) in a single image was higher in strain ultrasound elastography than in fine-needle aspiration cytology. CONCLUSION: Strain ultrasound elastography for highly and moderately suspicious nodules facilitated the detection of mildly suspicious, unsuspicious, and benign nodules.

Dada la mayor accesibilidad a la ecografía tiroidea, se diagnostican más nódulos de forma incidental aumentando su prevalencia al 65% en las tres últimas décadas. Todo ello ha supuesto un aumento de punciones innecesarias. El objetivo de nuestro estudio es identificar la utilidad de la clasificación TIRADS y de las características ecográficas de los nódulos tiroideos para establecer la probabilidad de malignidad de los mismos y seleccionar aquellos sospechosos para realizar la punción y aspiración con aguja fina (PAAF). Se encontró una relación estadísticamente significativa entre la malignidad y nódulo sólido, hipoecogenicidad, márgenes irregulares y microcalcificaciones. Sin embargo, no se encontró relación estadísticamente significativa entre malignidad y número de nódulos, tamaño nodular, diámetro craneocaudal y vascularización central. Asimismo, un 26.1% de los nódulos TIRADS-2 (todos ellos microcarcinomas), un 30% de los TIRADS-3 y un 54 % de los TIRADS-4 fueron malignos (p 0.027). Tanto el TIRADS como las características ecográficas aisladas son útiles para identificar nódulos sugerentes de malignidad.

Owed to the easier accessibility to thyroid ecography, more incidental nodules are discovered reaching their prevalence the 65 % of population in the last three decades. All of it has resulted in a growth of unnecessary fine needle aspirations (FNA). Our study objective is to identify the TIRADS classification utility and the nodules sonographic characteristics to establish their probability of malignancy and to select those suspicious susceptible of FNA. We found a statistically significant relationship between malignancy and solid nodule, hypoechogenicity, irregular margins and microcalcifications. However we didn´t find a relation between malignancy and number, size, shape (taller than wide) and central vascularity. With respect to TIRADS classification, 26,1% of TIRADS-2 (all of them microcarcinomas), 30% of TIRADS-3 and 54% of TIRADS-4 were malignant (p: 0,027). Both of them, TIRADS and individual sonographic characteristics are useful to identify nodules suspicious of malignancy.

RESUMEN Paciente masculino de 53 años con antecedentes de alergia, trabajador artesanal que realiza serigrafías, con alta exposición a productos químicos que, al someterse a altas temperaturas desprenden gran cantidad de vapor. Acude a consulta refiriendo que desde aproximadamente 2 meses antes presenta decaimiento con calambres musculares, palpitaciones, enrojecimiento de la cara y, aumento de tamaño de la glándula tiroides. Se diagnostica un bocio multinodular tóxico, por cifras hormonales elevadas. Se realiza ultrasonido de tiroides que informa bocio multinodular, una biopsia por aspiración con aguja fina, con atipia de significado incierto, y lesión folicular del tiroides. Se separa de su centro de trabajo y se logra revertir la sintomatología a los 15 días del tratamiento. Frecuentemente aparecen enfermedades asociadas a intoxicaciones por químicos y medicamentos, donde la presencia de hipertiroidismo no es habitual. Se requiere una anamnesis exhaustiva y exámenes complementarios específicos para un diagnóstico y tratamiento adecuados(AU)

ABSTRACT 53 years old male patient with a history of allergy; he works as a craft worker (producing serigraphs) very exposed to chemicals, which when subjected to high temperatures emit large amount of steam. The patient attends to the consultation referring that from approximately 2 months before he has been presenting weakness with muscle cramps, palpitations, flushing of the face and, increase in the size of the thyroid glands. It is diagnosed by the high hormonal figures a toxic multinodular goiter. Thyroid ultrasound is performed that shows multinodular goiter; it is also conducted a biopsy by fine-needle aspiration resulting in atypia of uncertain significance, and follicular lesion of the thyroid. The patient was separated from his workplace and there were reversed the symptoms after 15 days of treatment. Frequently appear diseases associated to poisonings caused by chemicals and medicines, where the presence of hyperthyroidism is not usual. It requires a comprehensive anamnesis and complementary tests that are specific for a proper diagnosis and treatment(AU)

Abstract Introduction: The fine-needle cytology is being used as a first line of investigation in the diagnosis of head and neck swellings, as it is simple, cost effective and less invasive as compared to biopsy. Objective: The aims of this study were to evaluate the results of the fine-needle non-aspiration cytology of cervical lymphadenopathy and to study the factors influencing the rate of non-diagnosis results. Methods: This retrospective study was conducted on selected patients with cervical lymphadenopathy that had undergone a fine-needle non-aspiration cytology followed by a histological biopsy. The sensitivity, specificity, positive predictive value and negative predictive value of fine-needle non-aspiration cytology for diagnosing tuberculosis were estimated. The risk factors of non-diagnosis results were evaluated. Results: The sensitivity, specificity, positive predictive value rates of fine-needle non-aspiration cytology for tuberculosis were 83.3%, 83.3%, 78.9% and 86.9% respectively. In total, 47 out of the 131 samples (35.8%) were considered non-diagnosis. Of the non-diagnosis samples, 84.2% (38 out of 47) were benign mostly due to tuberculosis (30 cases). Among the studied factors, only tuberculosis (confirmed by histopathological examination) was significantly associated with non-diagnosis cytology (p = 0.02, Odds-Ratio = 2.35). Conclusion: Tuberculosis is currently the commonest cause of cervical lymphadenopathy in North Africa. Fine-needle non-aspiration cytology is safe and accurate in the diagnosis of cervical tuberculous lymph node that is associated with the risk of non-diagnosis cytology.

Resumo Introdução: A punção não aspirativa com agulha fina tem sido utilizada como primeira linha de investigação no diagnóstico de tumores de cabeça e pescoço, por ser uma técnica simples, custo-efetiva e menos invasiva quando comparada à biópsia. Objetivo: Os objetivos deste estudo foram avaliar os resultados de citologia por punção não-aspirativa com agulha fina de linfadenopatias cervicais e estudar os fatores que influenciam a taxa de falha diagnóstica. Método: Este estudo retrospectivo foi realizado em pacientes selecionados com linfadenopatia cervical submetidos a punção não aspirativa com agulha fina, seguida por biópsia histológica. Foram estimadas a sensibilidade, especificidade, o valor preditivo positivo e valor preditivo negativo da punção não aspirativa com agulha fina para o diagnóstico de tuberculose. Os fatores de risco dos resultados com falha diagnóstica foram avaliados. Resultados: As taxas de sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo da punção não aspirativa com agulha fina para tuberculose foram de 83,3%, 83,3%, 78,9% e 86,9%, respectivamente. Das 131 amostras, 47 (35,8%) foram consideradas como falha diagnóstica. Das amostras não diagnosticadas, 84,2% (38 de 47) eram benignas, principalmente devido à tuberculose (30 casos). Entre os fatores estudados, apenas a tuberculose (confirmada pelo exame histopatológico) estava significativamente associada à citologia com falha diagnóstica (p = 0,02, odds ratio = 2,35). Conclusão: A tuberculose é atualmente a causa mais comum de linfadenopatia cervical no norte da África. A punção não aspirativa com agulha fina é uma técnica segura e precisa no diagnóstico de linfonodos cervicais associados ao risco de citologia com falha diagnóstica.

RESUMEN La presencia de la escleritis necrotizante es rara; necesita de un diagnóstico y de un tratamiento oportuno, ya que su curso es rápido, severo y destructivo de la integridad del globo ocular. Se presenta una paciente de 43 años de edad, quien requirió atención oftalmológica al presentar el ojo derecho rojo con intenso dolor. Se le encontraron 3 nódulos en la región antero-inferior escleral. Se le realizó punción-aspiración con aguja fina en los nódulos esclerales y se obtuvo un fragmento de uno de ellos para el corte histológico. En ambas muestras se observó infiltrado inflamatorio de linfocitos y neutrófilos con algunas células plasmáticas. Se le impuso tratamiento con prednisona oral (0,5 mg/kg/día), prednisolona colirio y azatioprina a dosis de 1,5 mg/kg/día. La evolución al mes fue satisfactoria con mejoría gradual de las lesiones. El tratamiento se mantuvo por 3 meses con chequeos hematológicos reiterados. Se disminuyeron posteriormente las dosis medicamentosas hasta su eliminación a los 6 meses. La curación de las lesiones fue total. No se encontró enfermedad sistémica en el chequeo clínico efectuado(AU)

ABSTRACT The presence of necrotizing scleritis is rare; it needs a diagnosis and an opportune treatment, since its course is fast, severe and destructive of the integrity of the eyeball. We present a 43-year-old patient who required ophthalmological attention when presenting the red right eye with intense pain. Three nodules were found in the antero-inferior scleral region. Fine needle aspiration was performed on the scleral nodules and a fragment of one of them was obtained for the histological section. In both samples, inflammatory infiltrate of lymphocytes and neutrophils with some plasma cells was observed. He was prescribed treatment with oral prednisone (0.5 mg /kg/day), prednisolone eye drops and azathioprine at a dose of 1.5 mg/kg/day. The evolution to the month was satisfactory with gradual improvement of the lesions. The treatment was maintained for 3 months with repeated blood tests. Drug doses were subsequently reduced until their elimination at 6 months. The healing of the injuries was total. No systemic disease was found during the clinical check-up(AU)

RESUMEN El cáncer cérvico uterino, causa alrededor de 250 000 muertes anuales en el mundo y alrededor de 400 en Cuba, a pesar del esfuerzo que realiza el MINSAP, a través del Programa de Pesquisaje. Con el mismo se puede obtener el diagnóstico de lesiones precursoras del cáncer de cuello uterino, este diagnóstico citológico se realiza en Cuba a través del método de Richard y Barron que demuestra que existe un progreso citológico aparente hasta llegar al cáncer, que comienza con neoplasia intraepitelial (NICI a NICIII y carcinoma in situ), hasta finalmente el cáncer invasor. Por otro lado existe el método de Bethesda que responde casi todas las interrogantes que la citología plantea para su enfrentamiento, evidentemente los mayores aportes y revisiones se enfocan al manejo de las citologías atípicas de significado incierto, ya que no sólo presentan un mayor número de posibles evaluaciones, sino que representan el mayor porcentaje de citologías alteradas y la inclusión del VPH en las lesiones de bajo grado. En Cuba todavía se clasifica por el método de Richard y no se utiliza el Bethesda. Por la alta incidencia de esta entidad el propósito de este trabajo es emitir consideraciones sobre la implementación del sistema de Bethesda en el diagnóstico citológico de lesiones precancerosas del cérvix.

ABSTRACT The cervical-uterine cancer causes almost 250 000 death a year around the world and around 400 in Cuba in spite of the efforts made by the Public Health Ministry through the Screening Program. With it, the diagnosis of lesions that are predecessors of the cervical cancer could be reached. This cytological diagnosis is carried out through the Richard and Barron method, showing that there is an apparent cytological progress leading to the cancer that begins with intraepithelial neoplasia (NICI and NICIII and carcinoma in-situ) and ends in the invasive cancer. From the other hand there is the Bethesda methods answering to all the questions cytology ask for confronting it. Obviously the biggest contributions and reviews are focused in the management of the atypical cytologies with uncertain significance since they not only have a higher number of possible evaluations, but also represent the highest percent of the altered cytologies and the inclusion of the HPV in low grade lesions. The classification in Cuba is still made by the Richard method and the Bethesda one is not used. Due to the high incidence of this entity, the aim of this article is exposing considerations on the implementation of the Bethesda system in the cytological diagnosis of cervix pre-cancerous lesions.

Introducción: el carcinoma diferenciado del tiroides representa la neoplasia maligna más frecuente en Endocrinología. Su presentación clínica y su diagnóstico se han modificado gracias a la disponibilidad de herramientas diagnósticas, tales como, el ultrasonido tiroideo y la biopsia aspirativa con aguja fina. Objetivos: describir las características clínicas, ultrasonográficas y citohistológicas de los pacientes intervenidos quirúrgicamente por enfermedad tiroidea maligna, y evaluar en ellos la prevalencia de hipocalcemia crónica y el valor de la hormona estimulante del tiroides. Métodos: se realizó un estudio descriptivo retrospectivo, en el cual se revisaron los informes consecutivos de Anatomía Patológica de todos los pacientes intervenidos quirúrgicamente por enfermedad tiroidea nodular en el Hospital General Provincial Camilo Cienfuegos en el periodo comprendido de enero de 2012 a diciembre 2014. La muestra estuvo conformada por 118 historias clínicas de pacientes operados por enfermedad tiroidea nodular que reunieron los criterios siguientes: datos clínicos, resultados según los criterios de Bethesda de la punción aspirativa con aguja fina, del ultrasonido del tiroides y la biopsia. A estos pacientes se les citó para una evaluación clínica y se les determinó en ayunas, la hormona estimulante del tiroides y en 2 días diferentes, la calcemia. Los pacientes fueron clasificados en portadores de: enfermedad tiroidea maligna (n= 39) y enfermedad tiroidea benigna (n= 79). Resultados: clínicamente solo el 15,4 por ciento de los pacientes con enfermedad tiroidea maligna presentaron dolor o molestia espontánea y/o a la palpación de la glándula del tiroides. La enfermedad tiroidea maligna se diagnosticó en todas las categorías del citodiagnóstico: I: 1/1 (100 por ciento), II: 8/83 (9,6 pòr ciento), III: 4/6 (66,7 por ciento), IV: 2/2 (100 por ciento), V: 18/20 (90 por ciento), VI: 6/6 (100 por ciento). El carcinoma papilar representó la neoplasia más frecuentemente diagnosticada (37/39 pacientes), el 33,3 por ciento de estos enfermos mostraron cifras de hormona estimulante del tiroides por encima de 2,0 mU/L, y hubo un 46,15 por ciento de hipocalcemia crónica. Conclusiones: el carcinoma papilar fue la neoplasia más frecuentemente diagnosticada en los pacientes operados por enfermedad tiroidea maligna. La mayoría de estos pacientes tuvieron un comportamiento subclínico, un tercio de valores no óptimos de la hormona estimulante del tiroides y una prevalencia alta de hipocalcemia crónica(AU)

ntroduction: differentiated thyroid carcinoma represents the most frequent malignant neoplasia in Endocrinology. Its clinical presentation and diagnosis have been modified thanks to the availability of diagnostic tools, such as thyroid ultrasound and fine needle aspiration biopsy. Objectives: to describe the clinical, ultrasonographic and cytohistological characteristics of patients undergoing surgery for malignant thyroid disease, and to evaluate in them the prevalence of chronic hypocalcemia and the value of the thyroid´s stimulating hormone. Methods: a retrospective descriptive study was carried out, in which consecutive reports of Pathological Anatomy of all patients surgically treated for nodular thyroid disease at Camilo Cienfuegos Provincial General Hospital in the period from January 2012 to December 2014 were reviewed. The sample consisted of 118 medical records of patients operated on for nodular-thyroid disease that met the following criteria: clinical data, results according to the Bethesda criteria of fine needle aspiration, thyroid ultrasound and biopsy. These patients were called for a clinical evaluation and they were indicated to be fasting. The patients were classified into carriers of: ETM (n=. 39) and benign thyroid disease (n= 79). Results: in clinical terms, only 15.4 percent of the patients with malignant thyroid disease presented spontaneous pain or discomfort, and / or during palpation of the thyroid glands. Malignant thyroid disease was diagnosed in all categories of cytodiagnosis: I: 1/1 (100 percent), II: 8/83 (9.6 percent), III: 4/6 (66.7 percent), IV: 2/2 (100 percent), V: 18/20 (90 percent), VI: 6/6 (100 percent). Papillary carcinoma represented the most frequently diagnosed neoplasm (37/39 patients); 33.3 percent of these patients showed thyroid stimulating hormone levels above 2.0 mU / L, and there was 46.15 percent of chronic hypocalcemia. Conclusions: papillary carcinoma was the most frequently diagnosed neoplasm in patients operated of malignant thyroid disease. The majority of these patients had a subclinical behavior, a third of non-optimal values of the thyroid stimulating hormone and a high prevalence of chronic hypocalcemia(AU)

Abstract Salivary gland tumors are relatively rare neoplasms, mostly located in the parotid gland, and few are malignant. Preoperative evaluation of salivary gland tumors includes fine needle aspiration cytology (FNAC). Objective The purpose of this study was to determine the importance of FNAC in the evaluation of rare salivary gland neoplasms. Material and Methods Four cases of rare salivary gland tumors were included, which were preoperatively assessed by clinical investigation, computed tomography, and FNAC. Results The presented cases include myoepithelial carcinoma, oncocytic carcinoma, undifferentiated lymphoepithelial carcinoma, and marginal zone lymphoma. Conclusion FNAC is a reliable diagnostic tool for common salivary gland neoplasms; however, rare tumors often represent diagnostic challenges. Clinical relevance In such rare tumors, the role of aspiration cytology may be limited to establishing the dignity of the lesion (benign/malignant). This knowledge enables the surgeon to choose the most appropriate therapeutic procedure. A definitive diagnosis of rare tumors (either epithelial or nonepithelial) is obtained by histological examination; cytology is limited in this regard due to overlapping features.

O objetivo com este estudo foi comparar as técnicas de citologia aspirativa, biópsia e citobloco para identificação e quantificação parasitológica de Leishmania (Leishmania) infantum chagasi em medula óssea de cães. Amostras de tecido medular de 26 animais, em diferentes estágios clínico-laboratoriais da doença, foram estudadas obedecendo-se os mesmos critérios de investigação nas técnicas de citologia aspirativa, biópsia e citobloco. O menor número de campos para a confirmação parasitológica foi constatado no esfregaço direto obtido por citologia aspirativa. O estágio clínico-laboratorial não influenciou no número de campos necessários para a primeira visualização do agente em nenhuma das técnicas (p>0,05), e menor intensidade parasitária foi observada nas lâminas de citobloco. As técnicas de citologia aspirativa e biópsia concordaram na estimativa do coeficiente de infectividade no tecido estudado (p<0,05). Apesar de a técnica de citobloco permitir a concentração de células e o melhor reaproveitamento de amostras, não demonstrou ser um método adequado para rápida identificação e quantificação parasitológica na leishmaniose visceral canina. Considerando-se suas vantagens, a citologia aspirativa foi o melhor método para detecção microscópica do parasito e determinação do nível de intensidade parasitária no tecido estudado.(AU)

The aim of the present study was to compare the aspiration cytology, biopsy and cell block techniques for identification and parasitological quantification of Leishmania (Leishmania) infantum chagasi in dog bone marrow. Bone marrow tissue samples from 26 animals, in different clinical-laboratory stages of the disease, were studied according to the same criteria of investigation in the aspiration cytology, biopsy and cell block techniques. The lowest number of fields for the parasitological confirmation was found in the direct smear obtained by aspiration cytology. The clinical-laboratory stage did not influence the number of fields required for the first visualization of the agent in any of the techniques (p> 0.05) and less parasitic intensity was observed in the cell block slides. The aspiration cytology and biopsy techniques agreed on the estimation of infectivity coefficient in the tissue studied (p< 0.05). Although the cell block technique allows the concentration of cells and better reutilization of samples, it has not been shown to be an adequate method for rapid identification and parasitological quantification in canine visceral leishmaniasis. Considering its advantages, aspiration cytology was the best method for microscopic detection of the parasite and determination of the level of parasite intensity in the tissue studied.(AU)

ABSTRACT Objectives The presence of thyroglobulin (Tg) in needle washouts of fine needle aspiration biopsy (Tg-FNAB) in neck lymph nodes (LNs) suspected of metastasis has become a cornerstone in the follow-up of patients with papillary thyroid carcinoma (PTC). However, there are limited data regarding the measurement of anti-Tg antibodies in these washouts (TgAb-FNAB), and it is not clear whether these antibodies interfere with the assessment of Tg-FNAB or whether there are other factors that would more consistently justify the finding of low Tg-FNAB in metastatic LNs. Materials and methods We investigated 232 FNAB samples obtained from suspicious neck LNs of 144 PTC patients. These samples were divided according to the patient’s serum TgAb status: sTgAb- (n = 203 samples) and sTgAb+ (n = 29). The TgAb-FNAB levels were measured using two different assays. Tg-FNAB was also measured using two assays when low levels (< 10 ng/mL) were identified in the first assay of the metastatic LNs from the sTgAb+ samples. Results The TgAb-FNAB results were negative in both assays in all samples. Low levels of Tg-FNAB were identified in 11/16 of the metastatic LNs of the sTgAb+ patients and 16/63 of the sTgAb- patients (p < 0.05) using assay 1. The measurement of the Tg-FNAB levels using assay 2 indicated additional metastases in 5 LNs of the sTgAb+ patients. Conclusions Factors other than the presence of TgAb-FNAB may contribute to the higher number of metastatic LNs with undetectable Tg-FNAB in the sTgAb+ group. In addition, the measurement of Tg-FNAB using different assays was useful to enhance the diagnosis of metastatic LNs, particularly when cytological and Tg-FNAB results are discordant.

Antecedentes: la enfermedad de Castleman es conocida como hiperplasia linfática angiofolicular y se caracteriza por crecimiento masivo del tejido linfático. Histológicamente hay tres categorías: hialino-vascular, tipo células plasmáticas y mixto. Se describen dos variantes clínicas: monocéntrica (localizada) y multicéntrica. Objetivo: presentar nuestra experiencia en el manejo de esta enfermedad haciendo énfasis en su compromiso mediastinal y pulmonar. Material y métodos: revisión de historias clínicas e informes patológicos. Resultados: se identificaron 5 pacientes, 1 mujer y 4 hombres, con edad promedio de 58,5 años. Tres pacientes presentaron la forma localizada y dos la multicéntrica. Los síntomas fueron: dolor torácico en dos casos, astenia en 1 caso y síndrome POEMS (polineuropata, organomegalia, endocrinopata y pico monoclo-nal) en 2 casos. Se realizó toracotomía y resección en 2 casos, lobectomía superior derecha en bloque con la lesión mediastinal en 1 caso, biopsia de masa apical en 1 caso y biopsia ganglionar por mediastinoscopia en 1 caso. Se realizó reoperación por sangrado en 1 caso. Tres pacientes presentaron la forma hialino-vascular y 2 la variante de células plasmáticas. Un paciente resecado se perdió de seguimiento. Los pacientes con síndrome POEMS fallecieron, uno al 8° día por neumonía intrahospitalaria y otro al 6° mes por sepsis. Los enfermos resecados restantes cursan buena evolución. Conclusiones: se recomienda la resección quirúrgica en pacientes con enfermedad de Castleman variedad localizada, la cual es curativa. Los pacientes con la variedad multicéntrica no se benefician con esta terapéu-tica, pero son pasibles de quimioterapia o radioterapia o combinación de ambas.

Background: Castleman's disease, known as angio follicular lymph node hyperplasia, is characterized by the massive growth of lymphoid tissue. Histollogically there are three categories: hyaline-vascular, plasm cell type and mixed type. Two clinical variantis have been described: monocentric (localized) and multicentric. Objective: to describe our experience in the treatment of this disease, focusing on itis mediastinal and pulmonary afecton. Method: review of clinical records and pathological reportis. Resultis: 5 patentis (1 female and 4 male), within an age -range of 58, 5 years were screened. Three patentis were afected by the localized type and two by the multicentric type. The symptoms were: thoracic pain in two of the cases, asthenia in one and POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy and monoclonal changes) in 2 cases. We performed thoracotomy and resecton in two cases, upper right side lobectomy in block with the mediastinal lesion in 1 case, apical mass biopsy in 1 case and lymph node biopsy by mediastinoscopy in one case. We performed reoperaton by bleeding in one case. Three patentis presented the hyaline vascular type and two, the plasma-cell type. We lost track of a resectoned patent. Those patentis with POEMS syndrome died, one of them of intra-hospital pneumonia on the eighth day, and another of sepsis on the sixth month. The remaining resectoned patentis are evolving well. Conclusions: on patentis presenting localized type Castleman's disease, we recommend surgical resecton, which is a curative therapy. Patentis presenting the monocentric type do not beneft from this therapy and are passible of chemotherapy and /or radiotherapy.

Introducción: el diagnóstico temprano del cáncer del pulmón es de vital importancia para tratar de disminuir la mortalidad por esta enfermedad (que es muy alta). La citología aspirativa con aguja fina transbronscoscópica juega un papel significativo en el diagnóstico y estadiamiento del carcinoma broncógeno. Objetivo: determinar la eficacia de la citología aspirativa con aguja fina transbroncoscópica en lesiones tumorales endobronquiales. Métodos: se realizó un estudio descriptivo, de corte transversal prospectivo, en pacientes a los que se les realizó citología aspirativa con aguja fina transbroncoscópica en lesiones endobronquiales, en el servicio de Neumología del Hospital Hermanos Ameijeiras, en el periodo comprendido entre enero de 2015 a enero de 2016. Se tomó en cuenta como variables la ubicación del tumor endobronquial, el diagnóstico citológico, el tipo de lesión tumoral y las complicaciones. Resultados: predominó el sexo masculino, el rango de edad mayor de 60 años y el color de piel blanca. Las lesiones fueron más frecuentes del lado derecho, fue más eficaz el proceder cuando los tumores se ubicaron hacia los bronquios inferiores, y se describían como masa tumoral o tipo mixta. La sensibilidad diagnóstica fue de aproximadamente 70 por ciento. El número de complicaciones fue muy bajo. Conclusiones: la biopsia aspirativa con aguja fina de tumores endobronquiales tiene un alto rendimiento diagnóstico con un número bajo de complicaciones(AU)

Introduction: Early diagnosis of lung cancer is vital in trying to reduce mortality from this disease (which is very high). Transbronscoscopic needle aspiration cytology plays a significant role in the diagnosis and staging of bronchogenic carcinoma. Objective: Determine the efficacy of transbronchoscopic needle aspiration cytology in endobronchial tumor lesions. Methods: A prospective, cross-sectional, descriptive study was performed in patients undergoing transbronchoscopic needle aspiration cytology in endobronchial lesions, in the Pulmonology Department of Hermanos Ameijeiras Hospital, from January 2015 to January 2016. The location of the endobronchial tumor, the cytologic diagnosis, the type of tumor lesion and the complications were taken into account as variables. Results: Age range was greater than 60, male gender and white skin color predominated. The lesions were more frequent on the right side, the procedure was more effective when the tumors were located towards the lower bronchi, and they were described as tumor mass or mixed type. The diagnostic sensitivity was approximately 70 percent The number of complications was very low. Conclusions: Spinal biopsy with fine needle of endobronchial tumors has a high diagnostic yield with a low number of complications(AU)

PURPOSE: We investigated factors predictive of false-negative pulmonary lesions with nonspecific benign cytology results on percutaneous transthoracic fine-needle aspiration biopsy (FNAB). MATERIALS AND METHODS: We included 222 pulmonary lesions that had a nonspecific benign result from percutaneous transthoracic FNAB between March 2005 and December 2012, and were confirmed by subsequent pathologic results or adequate clinical follow up over at least 2 years. Clinical, imaging, and biopsy procedure-related findings were compared between lesions with a final diagnosis of malignancy (false-negative) and lesions with a benign diagnosis (true-negative). Multivariate logistic regression analysis was performed to identify significant predictors of false-negatives. RESULTS: Of 222 lesions, 115 lesions were proved to be false-negatives, and 107 were true-negatives. Compared with the true-negatives, false-negative lesions showed significantly older age (p=0.037), higher maximum standardized uptake value (SUVmax) on positron emission tomography (p=0.001), larger lesion size (p=0.007), and lesion characteristics of a subsolid nodule (p=0.007). On multivariate logistic regression analysis, SUVmax, lesion size, and lesion characteristics were significant predictors of false-negative results. CONCLUSION: Among the clinical, radiologic, and procedure-related factors analyzed, high SUVmax, large lesion size, and subsolid lesions were useful for predicting malignancy in pulmonary lesions with nonspecific benign cytology results on FNAB.
