Resumo: Abstract Prolactin (PRL) secreting adenomas are associated with high incidence of headache. The role of hyperprolactinemia in the headache context is not clear, nor is the effect of its treatment on headache. Methods: The present longitudinal study evaluated hyperprolactinemic patients (69), in terms of presence and characteristics of headache before and after hyperprolactinemia treatment. Results: Headache was reported by 45 (65.2%) patients, independent of the etiology of hyperprolactinemia. The migraine phenotype was the most prevalent (66.6%). Medications used in the treatment of headache not changed during the study. The first line of treatment of hyperprolactinemia was dopaminergic agonists. In the last reevaluation, PRL level under treatment was within the reference range in 54.7% of the cases, and it was observed complete or partial resolution of the headache in 75% of the cases. The median PRL at this time in patients with complete headache resolution was 17 ng/mL, in those who reported partial recovery was 21 ng/mL, and in those in whom the headache did not change was 66 ng/mL, with a significant difference between the group with complete headache resolution vs. the group with unchanged headache (p=0.022). In the cases with complete headache resolution, the median fall on PRL levels was 89% and in those cases with partial headache resolution 86%, both significantly different (p<0.001) from the fall in the cases with an unchanged headache. Conclusion: Data allow us to conclude that, in this series, in the majority of cases the reduction in the level of PRL was followe3d by cessation or relief of the pain.

Resumo Os adenomas secretores de prolactina (PRL) estão associados à alta incidência de cefaleia. O papel da hiperprolactinemia no contexto da dor de cabeça não está claro, nem o efeito da redução dos níveis da PRL na cefaleia. Métodos: O presente estudo longitudinal avaliou pacientes hiperprolactinêmicos (69), quanto à presença e às características da cefaleia antes e após o tratamento da hiperprolactinemia. Resultados: Cefaleia foi relatada por 45 (65,2%) pacientes, independente da etiologia da hiperprolactinemia. O fenótipo de enxaqueca foi mais prevalente (66,6%). Os medicamentos usados ​​no tratamento da cefaleia não foram alterados durante o estudo. A primeira linha de tratamento da hiperprolactinemia foram os agonistas dopaminérgicos. Na última reavaliação, o nível de PRL sob tratamento estava dentro da faixa de referência em 54,7% dos casos, observando-se resolução completa ou parcial da cefaleia em 75% dos casos. A mediana de PRL neste momento em pacientes com resolução completa da cefaleia foi de 17 ng/mL, nos que relataram recuperação parcial foi de 21 ng/mL, e naqueles em que a cefaleia não se alterou foi de 66 ng/mL, com uma diferença significativa entre o grupo com resolução completa da cefaleia versus o grupo com cefaleia inalterada (p=0,022). Nos casos com resolução completa da cefaleia, a queda mediana nos níveis de PRL foi de 89% e nos casos com resolução parcial de cefaleia de 86%, ambos significativamente diferentes (p<0,001) da queda nos casos com cefaleia inalterada. Conclusão: Os dados permitem concluir que, nesta série, na maioria dos casos, a redução do nível de PRL foi seguida pela cessação ou alívio da dor.

Resumo: ABSTRACT Background: An inverse association between circulating vitamin D and adenoma risk hasbeen reported, but less is known about proximal inflammatory-hyperplastic polyps.Purpose: To investigate circulating 25(OH)D3and risk factors of proximal inflammatory-hyperplastic and adenoma colorectal polyps.Methods: From January 2017 to June 2019, consecutive asymptomatic average-risk partic-ipants undergoing initial screening colonoscopy. Questionnaires provided information oncolorectal polyp risk factors, and plasma samples were assayed for 25-Hydroxyvitamin-D ­25(OH)D3. The colorectal polyps were assessed, and medical history and demographic datawere obtained from each patient.Results: Of the 220 asymptomatic subjects, the prevalence of proximal inflammatory-hyperplastic polyps and adenoma polyps were 16.8%; 18.1% and 22.2%, respectively.Multivariate analysis revealed that low vitamin D (25(OH)D3< 18 ng/mL, OR = 3.94; 95%CI: 1.81­9.51) and current/former smoking (OR = 6.85; 95% CI: 2.98­15.70), high bodymass index (BMI > 24, OR = 5.32, 95% CI: 2.62­4.71) were independent predictors forproximal inflammatory-hyperplastic colorectal polyps (non-adenoma). Low vitamin D(25(OH)D3< 18 ng/mL, OR = 7.75; 95% CI: 3.19­18.80) and current/former smoking (OR = 3.75;95% CI: 1.30­10.81), age over 60 years old (OR = 2.38, 95% CI: 1.02­5.57), were independentpredictors for adenoma colorectal polyps.Conclusion: Low vitamin D and smoking are common risk factors for both adenomatous andproximal inflammatory hyperplastic polyps. Old age and BMI are additional risk factors forthe development of adenomatous and non-adenomatous colorectal polyps.

Título: Adenoma hipofisario ectópico del seno esfenoidal persistente tras cirugía manejado con tratamiento conservador / Ectopic pituitary adenoma in the sphenoid sinus persistent after surgery managed with conservative treatment
Fonte: Rev. chil. endocrinol. diabetes;13(4):150-153, 2020. ilus.
Idioma: es.
Resumo: Los adenomas hipofisarios ectópicos (EPA) constituyen un reto diagnóstico, dada su escasa prevalencia y variada presentación en la que puede incluirse un síndrome de hipersecreción de hormonas hipofisarias. La clínica suele ser larvada e inespecífica, no presentan ninguna característica radiológica diferencial y el diagnóstico habitualmente es anatomopatológico. Sin embargo, a pesar de ser tumores benignos, pueden presentar un comportamiento agresivo, con invasión ósea y difícil resección completa, por lo que un diagnóstico de sospecha precoz podría resultar en un tratamiento más eficaz y con un menor número de complicaciones. Presentamos el caso de una paciente con un adenoma hipofisario ectópico silente en el seno esfenoidal con inmunohistoquímica positiva para Hormona de crecimiento (GH) y prolactina que presentaba restos tumorales tras la intervención quirúrgica y ha sido manejada con tratamiento médico conservado, con buenos resultados.

Ectopic pituitary adenomas constitute a diagnostic challenge, given their low prevalence and varied presentation in which a pituitary hormone hypersecretion syndrome may be included. Clinical symptoms are usually latent and nonspecific, they have no differential radiological characteristics and the diagnosis is usually anatomopathological. However, despite being benign tumors, they can exhibit aggressive behavior, with bone invasion and difficult complete resection, so a diagnosis of early suspicion could result in more effective treatment and fewer complications. We present the case of a patient with a silent ectopic pituitary adenoma in the sphenoid sinus with positive immunohistochemistry for Growth Hormone (GH) and prolactin who had tumor remnants after surgery and was managed with conservative medical treatment, with good results.

Título: Hipertiroidismo en personas mayores de 65 años: serie de casos de un hospital universitario / Thyrotoxicosis in the elderly: case series report from a university hospital
Fonte: Rev. chil. endocrinol. diabetes;13(4):166-169, 2020. tab.
Idioma: es.
Resumo: Introducción: En Chile en las últimas décadas ha aumentado la población de personas mayores de 65 años. La tirotoxicosis en este grupo está asociada a complicaciones como fibrilación auricular (FA), insuficiencia cardiaca (ICC), osteoporosis y aumento de la mortalidad. En algunos casos puede presentarse con síntomas no específicos, cuadro conocido como hipertiroidismo apático. Objetivos: Evaluar las características clínicas de la tirotoxicosis en personas mayores. Método: Serie de casos retrospectiva. Se analizaron fichas clínicas de pacientes mayores de 65 años con el diagnóstico de tirotoxicosis controlados en nuestro centro entre enero de 2012 y mayo de 2018. Resultados: En el periodo estudiado 54 pacientes fueron diagnosticados de tirotoxicosis. Se excluyen 4 por datos incompletos. El 80% corresponden a mujeres. La mediana de edad fue 71 años (rango 65-94), sin diferencias por género (p=0,61). La etiología más frecuente fue enfermedad de Graves (EG) en 64%, seguido por bocio multinodular hiperfuncionante en 20%, adenoma tóxico en 10% y asociada a fármacos en 6%. De los pacientes con EG, 28% presentó orbitopatía distiroidea (OD) clínicamente evidente. Un 30% se diagnosticó en contexto de baja de peso, deterioro cognitivo o patología cardiovascular, sin presentar síntomas clásicos de hipertiroidismo. Un 16% presentó FA, 14% ICC y 6% fractura osteoporótica. El 28% fue diagnosticado durante una hospitalización o requirió ser hospitalizado durante los meses siguientes. Los mayores de 75 años presentan una mayor probabilidad de hipertiroidismo apático (OR 5,1, IC95% 1,15-22,7 p=0,01). Además, las complicaciones aumentan en mayores de 75 años, encontrándose en este grupo todos los casos de FA. Conclusiones: La etiología más común de tirotoxicosis fue la EG, a diferencia de lo reportado en otras poblaciones. Un número importante de pacientes debutó sin síntomas clásicos de hipertiroidismo, principalmente mayores de 75 años, por lo que se debe tener una alta sospecha en este grupo etario.

Introduction: Hyperthyroidism in the elderly can produce severe complications such as atrial fibrillation (AF), heart failure (CHF) and osteoporosis. In the elderly, thyrotoxicosis may have only nonspecific symptoms, known as apathetic hyperthyroidism. Objective: To evaluate the clinical characteristics of thyrotoxicosis in the elderly. Methods: Retrospective case series. We reviewed clinical records of patients with thyrotoxicosis older than 65 years, between January 2012 and March 2019. Results: During this period, 54 patients were diagnosed with thyrotoxicosis. Four patients were excluded due to incomplete data. 80% were women. The average age was 73 years (range 65-94), without age difference between gender (p=0,61). The most frequent etiology was Graves' disease in 64%. Hyperfunctioning multinodular goiter was confirmed in 20%, toxic adenoma in 10% and drug-associated in 6%. Twenty eight percent of Graves' disease patients had dysthyroid orbitopathy. Thirty percent presented as apathetic hyperthyroidism. Sixteen percent of the patients presented AF, 14% CHF, and 6% osteoporotic fracture. Twenty-eight percent were diagnosed during hospitalization or required hospitalization in the following months. Those older than 75 years had a greater probability of presenting apathetic hyperthyroidism (OR 5.1, 95% CI 1.15- 22.7 p=0.01). Complications increase in this age group, with all cases of AF. Conclusions: The most common etiology of thyrotoxicosis in this group was GD. This differs from other populations. A significant number of patients presented without classic symptoms of hyperthyroidism, especially in people older than 75 years. Special attention should be paid to atypical symptoms of hyperthyroidism in this group.

Resumo: Introducción: Los tumores de hipófisis representan aproximadamente un 10% de los tumores intracraneales. Los adenomas hipofisarios son ampliamente la lesión selar más frecuente. Es fundamental que se conformen equipos capaces de tratar holísticamente esta patología en las distintas regiones de nuestro vasto territorio. El propósito del presente trabajo es presentar nuestra experiencia en el manejo quirúrgico de los adenomas hipofisarios en el Noroeste Argentino. Materiales y métodos: Estudio retrospectivo de pacientes operados por adenomas selares, desde enero de 2013 hasta abril de 2019, en la provincia de Tucumán, por el autor Senior. Resultados: Se analizaron 211 pacientes operados de adenomas pituitarios. En el 75% (n=158) las resecciones fueron totales y en el 25% (n=53) fueron resecciones subtotales. De los 88 pacientes con macroadenomas no funcionantes y déficit visual, el 94% (n=83) presentó mejoría visual en el postoperatorio. De los 52 pacientes con acromegalia, un 75% (n=39) presentó remisión bioquímica completa postquirúrgica. De los 26 pacientes con enfermedad de Cushing, un 81% (n=21) presentó remisión bioquímica completa postquirúrgica. De los 21 pacientes con prolactinomas, un 71% (n=15) normalizaron los niveles de prolactina en el postoperatorio. Conclusión: Los resultados en el tratamiento quirúrgico de los adenomas hipofisarios de la presente serie son comparables a los reportados por centros especializados internacionales. Debemos formar equipos capaces de tratar esta patología en las distintas regiones de la Argentina.

Background: Pituitary tumors account for 10% of intracranial tumors. Pituitary adenomas are the most common selar lesion. It is essential that teams be formed capable of treating this pathology holistically in the different regions of our vast territory. The purpose of this article is to present our experience in the surgical management of pituitary adenomas in the Northwest of Argentine. Materials and methods: A retrospective analysis was done studding patients operated from pituitary adenomas, from January 2013 to April 2019, in Tucumán, by the Senior Author. Results: We analyzed 211 patients operated from pituitary adenomas, of which 75% (n=158) had gross total resections and 25% (n=53) had subtotal resections. Of the 88 patients with non-functioning macroadenomas and visual deficit, 94% (n=83) presented visual improvement after surgery. Of the 52 patients with acromegaly, 75% (n=39) presented complete biochemical remission after surgery. Of the 26 patients with Cushing's disease, 81% (n=21) presented complete biochemical remission after surgery. Of the 21 patients with prolactinomas, 71% (n=15) normalized prolactin levels after surgery. Conclusion: Our results in the surgical treatment of pituitary adenomas are comparable to those reported by international specialized centers. We must form teams capable of treating this pathology in the different regions of Argentina

Idioma: en.
Resumo: Abstract Background: Majority of the incidentally discovered adrenal masses, called adrenal incidentaloma (AI), are nonfunctioning adrenal adenomas. The appropriate management of AI is still a matter debate, so it is necessary to investigate their associated morbidity. However, data regarding morphological and functional cardiac alterations are limited in this group. Objective: In this study, we aimed to assess cardiac structural and functional characteristics and atrial conduction properties in patients with nonfunctioning AI. Methods: Thirty patients with nonfunctioning AI and 46 properly matched control subjects were included in the study. After hormonal and biochemical analysis, all participants underwent transthoracic echocardiography to obtain systolic and diastolic parameters of both ventricles, in addition to atrial conduction times by tissue Doppler echocardiography. Data were analyzed with Statistical Package for the Social Sciences (SPSS, Chicago, IL, United States) statistics, version 17.0 for Windows. P < 0.05 was considered statistically significant. Results: Left ventricular (LV) mass index and LV myocardial performance index were significantly increased in AI group. Among atrial conduction times, both intra- and interatrial electromechanical delays were significantly prolonged in patients with nonfunctioning AI. Other laboratory and echocardiographic findings were similar between groups. Conclusion: Our study revealed that intra- and inter-atrial conduction times were prolonged, and LV mass index was increased in patients with nonfunctioning AI. These findings may be markers of subclinical cardiac involvement and tendency to cardiovascular complications. Close follow-up is necessary for individuals with nonfunctioning AI for their increased cardiovascular risk.

Resumo Fundamento: A maioria das massas adrenais descobertas incidentalmente, denominadas incidentaloma adrenal (IA), são adenomas adrenais não funcionantes. O manejo adequado da IA ainda é um tema de debate, e por isso é necessário investigar suas morbidades associadas. Entretanto, dados referentes a alterações cardíacas morfológicas e funcionais são limitados nesse grupo. Objetivo: Neste estudo, objetivamos avaliar as características estruturais e funcionais cardíacas e as propriedades de condução atrial em pacientes com IA não funcionante. Métodos: Trinta pacientes com IA não funcionante e 46 controles adequadamente pareados foram incluídos no estudo. Após análise hormonal e bioquímica, todos os participantes foram submetidos a ecocardiograma transtorácico para obtenção de parâmetros sistólicos e diastólicos de ambos os ventrículos, além dos tempos de condução atrial pelo ecocardiograma com Doppler tecidual. Os dados foram analisados com o Statistical Package for the Social Sciences (SPSS, Chicago, IL, Estados Unidos), versão 17.0 para Windows. P < 0,05 foi considerado estatisticamente significativo. Resultados: O índice de massa do ventrículo esquerdo (VE) e o índice de desempenho miocárdico do VE foram significativamente aumentados no grupo IA. Entre os tempos de condução atrial, os atrasos eletromecânicos intra- e interatriais foram significativamente prolongados em pacientes com IA não funcionante. Outros achados laboratoriais e ecocardiográficos foram semelhantes entre os grupos. Conclusão: Nosso estudo revelou que os tempos de condução intra- e interatrial estavam prolongados e o índice de massa do VE estava aumentado em pacientes com IA não funcionante. Esses achados podem ser marcadores de envolvimento cardíaco subclínico e de tendência a complicações cardiovasculares. Um acompanhamento rigoroso é necessário para indivíduos com IA não funcionante, devido ao aumento do risco cardiovascular.

Título: Situación actual del cáncer de colon en Chile: una mirada traslacional / The present situation of colorectal cancer in Chile
Fonte: Rev. méd. Chile;148(6):858-867, jun. 2020. graf.
Idioma: es.
Resumo: Colorectal (CRC) is one of the most common types of cancer worldwide. Most tumors develop from an adenoma in a period of 10 to 15 years, but some may appear without previous adenomatous lesions. Seventy-five percent of colorectal cancers are sporadic, 20% have a family component (first or second-degree relatives with CRC) and 5% have a hereditary predisposition with a Mendelian pattern. The epidemiological evolution in the recent years in Chile has a worrisome evolution and the treatment costs of advanced stages are a burden for the healthcare system. We herein highlight the main Chilean medical and scientific contributions on the pathogenesis, early diagnosis, and treatment of CRC, which lead to its better understanding, and therefore better management, based on local evidence.

Fonte: Rev. cuba. cir;48(4), sept.-dic. 2009.
Idioma: es.
Resumo: INTRODUCCIÓN. El objetivo del presente estudio fue evaluar la indicación y los resultados de la microcirugía endoscópica transanal (TEM) para el tratamiento de los tumores benignos y malignos del recto, en el Centro Nacional de Cirugía de Mínimo Acceso (La Habana). MÉTODOS. Se realizó una amplia revisión bibliográfica acerca del manejo actual de los tumores benignos y malignos de recto mediante TEM y se evaluaron los resultados de dicha técnica en un período de 4 años en el Centro Nacional de Cirugía de Mínimo Acceso. RESULTADOS. En el período estudiado se operaron 33 pacientes mediante esta técnica. Las principales indicaciones de la TEM fueron los adenomas (72,8 por ciento). El tiempo quirúrgico promedio fue de 189,1 min; se usó transfusión intraoperatoria en 4 pacientes (12,1 por ciento) y la estancia hospitalaria fue de 2,5 días. Las principales complicaciones transoperatorias fueron el sangramiento y la perforación en la cavidad peritoneal. Las complicaciones posoperatorias fueron la fístula rectovaginal, el sangramiento y la dehiscencia. El seguimiento de los pacientes osciló entre 1 y 54 meses (media 28,3), y se encontraron 2 recidivas locales en el grupo de los adenomas. CONCLUSIONES. La TEM es un método seguro y eficaz para el tratamiento de los tumores benignos y malignos del recto (en estadios iniciales). Es la técnica de elección en grandes adenomas rectales y cánceres de recto con estadios pT1 localizados en toda la ampolla rectal. Tiene todas las ventajas de la cirugía de mínimo acceso; los resultados de recidiva son similares a los de la cirugía abdominal y no tiene complicaciones de disfunción urinaria o sexual y las de incontinencia fecal son mínimas(AU)

INTRODUCTION: The aim of present study was to assess the indication and the results of transanal endoscopic microsurgery (TEM) for treatment of rectal benign and malign tumors in National Center of Minimal Access Surgery in Havana city. METHODS: A comprehensive review of literature was made on present managing of rectal benign and malign tumors by TEM and results of such technique were assessed during 4 years in National Center of Minimal Access Surgery. RESULTS: During study period 33 patients were operated on by this technique. Main indications of TEM were the presence of adenomas (72,8 percent). Mean surgical time was of 189,1 minutes; in 4 patients ( 12,1 percent) transoperative transfusion was used, and hospital stay was of 2,5 days. Main transoperative complications were the rectovaginal fistula, bleeding and dehiscence. Follow-up of patients fluctuates between 1 and 54 months (mean 28,3) with 4 local relapses in adenoma group. CONCLUSIONS: TEM is a safe and effective method for treatment of rectal benign and malign tumors (in early stages). It is the choice technique for the big rectal adenomas and rectum cancer with pT1 stages located in all the ampulla of rectum. It has all advantages of the minimal access surgery; relapse results are similar to that of abdominal surgery without complications of urinary or sexual dysfunction and that of fecal incontinence are minimal(AU)

Título: Hiperparatiroidismo primario por adenoma con gammagrafía negativa / Primary hyperparathyroidism due to negative scintigraphy adenoma
Fonte: Rev. cuba. med;59(3):e1324tab.
Idioma: es.
Resumo: Introducción: El hiperparatiroidismo es una de las causas más frecuente de hipercalcemia. El 85 por ciento de los pacientes son mayores de treinta años, su frecuencia más alta se encuentra por encima de 60 años, a largo plazo puede producir una serie de complicaciones. Objetivo: Describir el caso clínico de hiperparatiroidismo primario que resultó negativa al estudio de gammagrafía con localización ectópica del adenoma. Caso Clínico: Paciente femenina de 20 años con antecedentes de litiasis renal y uretral de 7 años de evolución, la cual se sometió a 13 sesiones de litotricia y dos cirugías renales con recidivas, hace 6 meses se detectó cifras elevadas de calcio. Se realiza protocolo de estudio de hipercalcemia determinándose hiperparatiroidismo primario, ultrasonido y tomografía de cuello reportan lesión que podría corresponder a un adenoma paratiroideo paratraqueal; sin embargo, la gammagrafía con metoxi-isobutilisonitrilo y tecnecio 99 fue negativa. Se realizó cirugía de cuello convencional ya que la cirugía radioguiada no fue útil para la localización del adenoma paratiroideo intraoperatorio. Estudio histopatológico reportó adenoma paratiroideo. Conclusiones: En adenomas paratiroideo con gammagrafía negativa se puede hacer el diagnostico con estudios de imagen convencional. La localización ectópica del adenoma paratiroideo constituye una causa de gammagrafía negativa. La cirugía radioguiada no es útil en los adenomas paratiroides ectópicos con gammagrafía negativa(AU)

Introduction: Hyperparathyroidism is one of the most frequent causes of hypercalcemia. 85 percent of patients are older than thirty years, its highest frequency is over 60 years, in the long term it can produce a series of complications. Objective: To describe a clinical case of primary hyperparathyroidism that was negative in the scintigraphy study with ectopic location of the adenoma. Clinical case report: A 20-year-old female patient with a 7-year history of renal and urethral lithiasis, who had undergone 13 lithotripsy sessions and two recurrent kidney surgeries. Six months ago, elevated calcium levels were detected. A study protocol for hypercalcemia was carried out, determining primary hyperparathyroidism. Ultrasound and neck tomography report a lesion that could correspond to a paratracheal parathyroid adenoma; however, methoxy-isobutylisonitrile and technetium-99 scintigraphy was negative. Conventional neck surgery was performed since radioguided surgery was not useful for locating the intraoperative parathyroid adenoma. Histopathological study reported parathyroid adenoma. Conclusions: In parathyroid adenomas with negative scintigraphy, the diagnosis can be reached with conventional imaging studies. The ectopic location of the parathyroid adenoma is a cause of negative scintigraphy. Radioguided surgery is not helpful in scan-negative ectopic parathyroid adenomas(AU)

Título: Metanephric Adenoma with cystic changes- An uncommon presentation of a rare tumor in a young adult
Fonte: Autops. Case Rep;10(3):e2020148, 2020. graf.
Idioma: en.
Resumo: Metanephric adenoma (MA) is a rare benign neoplasm of the kidney that is usually asymptomatic and incidentally diagnosed. MA usually present as a solid mass; however, a cystic presentation has been reported. The main differential diagnosis of MA is the epithelial predominant Wilms tumor (e-WT) and the solid variant of papillary renal cell carcinoma (pRCC). The presence of the BRAF gene mutation has recently been reported in 85% of MA, and less than 10% of cases of MA do not express this specific gene mutation. Herein we report a 22-year-old man who presented with back pain and abdominal discomfort with a renal mass on the computed tomographic scan. The diagnosis of metanephric adenoma was confirmed histopathologically. In our case, the tumor presented as a solid and cystic mass hence mimicking a papillary renal cell carcinoma. The VE1 protein, which correlates with BRAF gene mutation, did not show any significant expression. We want to highlight that MA can present as a cystic lesion that should be taken into account to avoid unnecessary radical nephrectomy. Also, we demonstrated that a subset of MA might not harbor the BRAF gene and, they are classified as the BRAF wild type MA.
