Avaliação dos pacientes com hiperparatireoidismo primário submetidos à paratireoidectomia no INCA RJ, Brasil) no período de janeiro 1998 até maio 2022 / Evaluation of patients with primary hyperparathyroidism who underwent parathyroidectomy at INCA (RJ, Brazil) from January 1998 to May 2022

Introdução: o hiperparatireoidismo primário (HPTP) é um distúrbio endócrino comum, tipicamente caracterizado por hipercalcemia e níveis elevados ou inapropriadamente normais do hormônio da paratireoide (HPT). O HPTP resulta da secreção autônoma e excessiva do HPT de uma ou mais glândulas paratireoides. O HPTP é benigno e causado por adenoma, na maioria dos casos. Os elementos essenciais para definir a natureza benigna ou maligna da paratireoide requerem informações clínicas juntamente com as peças cirúrgicas para avaliação patológica, além de elementos não essenciais como avaliação bioquímica pré-operatória e achados operatórios, auxiliando na definição dessa doença. Objetivo: descrever o perfil clínico-epidemiológico dos pacientes com HPTP operados no Instituto Nacional de Câncer (INCA). Método: estudo epidemiológico observacional descritivo com desenho transversal retrospectivo de pacientes maiores de 18 anos de idade, de ambos os sexos, submetidos à paratireoidectomia no INCA, cujas peças cirúrgicas e laudos histopatológicos estavam registradas pela Divisão de Patologia (DIPAT), além do registro bioquímico da elevação do HPT no pré-operatório, no período de janeiro de 1998 até maio 2022. Resultados: dos 28 prontuários avaliados, verificou se que 78,6% dos pacientes eram do sexo feminino; relação mulher/homem de 3 a 4:1; a idade média foi de 55 anos; 75,0% tinham adenoma como principal causa de HPTP, seguido do carcinoma da paratireoide (CP) (14,3%); como fator etiológico da tumorigênese, 14,3% fazem parte da síndrome endócrina hereditária, incluindo neoplasia endócrina múltipla (NEM). 71,2% dos pacientes com HPTP são sintomáticos; 57,3% manifestação esquelética pré-operatória, sendo a dor óssea (28,8%), o sintoma mais frequente, 17,8% radiograficamente representado pelo tumor marrom; 53,5% manifestação renal pré-operatória, 42,8% radiograficamente representado por litíase renal. O principal fator de risco para carcinoma da paratireoide (CP) pré-operatório foi a avaliação bioquímica com dosagem sérica pré-operatório do cálcio, PTH e fósforo (p<0,05). Finalizando, a média de seguimento foi de 31,1 meses, com a cura cirúrgica (92,8%) como principal desfecho clínico seguido de doença estrutural (7,2%). Durante todo o seguimento 17,8% evoluíram com óbito. Conclusão: evidenciou-se uma população de HPTP de maioria benigna, tipicamente por adenoma com manifestação sintomática, com hipercalcemia acentuada, onde CP foi a segunda causa mais prevalente do HPTP operado no INCA

Introduction: Primary hyperparathyroidism (PHPT) is a common endocrine disorder, typically characterized by hypercalcemia and elevated or inappropriately normal levels of parathyroid hormone (PTH). HPTP results from autonomous and excessive secretion of HPT from one or more parathyroid glands. HPTP is benign and caused by adenoma in most cases. The essential elements to define the benign or malignant nature of the parathyroid require clinical information together with the surgical specimens for pathological evaluation, in addition to non-essential elements such as preoperative biochemical evaluation and operative findings, helping to define this disease. Objective: to describe the clinical-epidemiological profile of patients with PHPT operated on at Brazilian National Cancer Institute (INCA). Method: descriptive observational epidemiological study with retrospective cross-sectional design of patients over 18 years of age, of both sexes, submitted to parathyroidectomy at INCA, whose surgical specimens and histopathological reports were registered by the Division of Pathology (DIPAT), in addition to the biochemical registry preoperative HPT elevation, from January 1998 to May 2022. Results: of the 28 medical records evaluated, it was found that 78.6% of the patients were female; female/male ratio from 3 to 4:1; the average age was 55 years; 75.0% had adenoma as the main cause of PHPT, followed by parathyroid carcinoma (PC) (14.3%); as an etiological factor of tumorigenesis, 14.3% are part of the hereditary endocrine syndrome, including multiple endocrine neoplasia (MEN). 71.2% of patients with PHPT are symptomatic; 57.3% preoperative skeletal manifestation, with bone pain (28.8%) being the most frequent symptom, 17.8% radiographically represented by the brown tumor; 53.5% preoperative renal manifestation, 42.8% radiographically represented by renal lithiasis. The main risk factor for preoperative parathyroid carcinoma (PC) was the biochemical evaluation with preoperative serum levels of calcium, PTH and phosphorus (p<0.05). Finally, the mean follow-up was 31.1 months, with surgical cure (92.8%) as the main clinical outcome, followed by structural disease (7.2%). During the entire follow-up, 17.8% died. Conclusion: a benign majority of PHPT population was evidenced, typically due to adenoma with symptomatic manifestation, with severe hypercalcemia, where CP was the second most prevalent cause of PHPT operated at INCA

[Primary lymph node gastrinoma]. / Gastrinoma primario de ganglio linfático.

Gastrinomas are neuroendocrine tumors usually located in the duodenum and pancreas, in the context of a Multiple Endocrine Neoplasm and forming a Zollinger-Ellison syndrome. The location of this type of lymph node tumor is extremely unusual and its early diagnosis constitutes a real challenge to be able to establish an adequate treatment and manage the complications that these entail. We present the case of a 64-year-old male patient with a lymph node gastrinoma and whose surgical removal resulted in the immediate remission of the patient's symptoms.

Neoplasia endócrina múltipla tipo 2A: relato de caso / Multiple endocrine neoplasia type 2A: a case report / Neoplasia endocrina múltiple tipo 2A: reporte de caso

As neoplasias endócrinas múltiplas (NEM) são síndromes genéticas autossômicas dominantes implicadas no desenvolvimento de neoplasias benignas ou malignas, envolvendo ao menos duas glândulas endócrinas. Entre seus subtipos, está a NEM2A, que consiste em carcinoma medular de tireoide (CMT), feocromocitoma e hiperparatireoidismo. Este texto apresente o relato de caso de um paciente de 40 anos, previamente hígido, que passou a apresentar episódios de cefaleia associada a sudorese profusa, vômitos e taquicardia. Evoluiu com distensão abdominal intensa após alimentação por via oral, perda ponderal, desnutrição, astenia, obstipação, humor deprimido e picos pressóricos. Exames laboratoriais evidenciaram alterações dos hormônios tireoidianos, PTH e hormônios da adrenal. Foi levantada a suspeita clínica de NEM2A, posteriormente corroborada pelos diagnósticos anatomopatológicos de feocromocitoma e CMT, associados à presença de hiperparatireoidismo. Foi possível concluir que, a despeito de sua baixa prevalência na população geral, a NEM é uma síndrome clínica de grande relevância, tendo em vista os impactos para os pacientes e famílias acometidas. Dessa forma, é necessário que os profissionais de saúde tenham conhecimento acerca da síndrome e que o Sistema Único de Saúde (SUS) esteja apto a assistir aos pacientes portadores de NEM, possibilitando diagnóstico precoce e tratamento adequado.

Multiple endocrine neoplasias (MEN) are dominant autosomal genetic syndromes involved in the development of benign or malignant tumors in at least two endocrine glands. MEN2A is one of its subtypes, which consists of medullary thyroid carcinoma (MTC), pheochromocytoma, and hyperparathyroidism. This study reports the case of a healthy 40-year-old male patient presenting with episodes of headache associated with profuse sweating, vomiting, and tachycardia. The patient evolved with severe abdominal distension after oral feeding, weight loss, malnutrition, asthenia, constipation, depressed mood, and pressure peaks. Laboratory tests showed abnormalities in thyroid, parathyroid (PTH), and adrenal hormones ­ thus raising the hypothesis of MEN2A, which was later corroborated by the histological diagnosis of pheochromocytoma and MTC, associated with hyperparathyroidism. The results indicate that, despite its low prevalence in the general population, MEN has a great impact on affected patients and families, thus being a relevant clinical syndrome. For enabling early diagnosis and adequate treatment, health professionals must be familiarized with such a condition, and the Brazilian Unified Health System (SUS) must be able to assist affected patients.

Las neoplasias endocrinas múltiples (NEM) son síndromes genéticos autosómicos dominantes involucrados en el desarrollo de neoplasias benignas o malignas, que afectan al menos dos glándulas endocrinas. Entre sus subtipos se encuentra NEM2A, que consiste en carcinoma medular de tiroides (CMT), feocromocitoma e hiperparatiroidismo. Este es un reporte de caso de un paciente de 40 años de edad, previamente sano, que comenzó a presentar episodios de cefalea asociada a sudoración profusa, vómitos y taquicardia. Evolucionó con distensión abdominal severa después de alimentarse, pérdida de peso, desnutrición, astenia, estreñimiento, estado de ánimo deprimido y picos de presión. Las pruebas de laboratorio mostraron alteraciones en las hormonas tiroideas, PTH y hormonas suprarrenales. Se planteó la hipótesis de MEN2A, posteriormente corroborada por el diagnóstico anatomopatológico de feocromocitoma y CMT, asociado a hiperparatiroidismo. Se pudo concluir que, a pesar de su baja prevalencia en la población general, el NEM es un síndrome clínico de gran relevancia, dado el impacto que tiene en los pacientes y familiares afectados. Por tanto, es necesario que los profesionales sanitarios tengan conocimiento sobre el síndrome y que el Sistema Único de Salud (SUS) sea capaz de asistir a los pacientes con NEM, posibilitándoles diagnóstico precoz y tratamiento adecuado.

Manifestaciones maxilofaciales en una familia chilena con adenomatosis poliposa familiar / Maxillofacial manifestations in a Chilean family with familial adenomatous polyposis

RESUMEN: La Poliposis Adenomatosa Familiar (PAF) es un síndrome hereditario autosómico dominante causado por la mutación del gen APC. En su forma clásica se desarrollan más de 100 pólipos adenomatosos intestinales que progresan a cáncer colorrectal en casi el 100% de los casos no tratados. Dentro de las manifestaciones extracolónicas de PAF, se encuentran las maxilofaciales, como: osteomas y alteraciones dentales, que pueden preceder por años al desarrollo de poliposis colónica. A pesar de que en Chile hay estudios de PAF y cáncer de colon, son escasos los reportes de manifestaciones maxilofaciales en estos pacientes. En la familia en estudio se encontró manifestaciones descritas previamente como: odontoma, osteomas y malformaciones de incisivos; adicionalmente tags mucosos que no se han asociado previamente al síndrome.

ABSTRACT: Familial adenomatous polyposis (FAP) is an autosomal dominant hereditary syndrome caused by the mutation of the APC gene. In its classic form, more than 100 intestinal adenomatous polyps progress to colorectal cancer in almost 100% of cases if they are not treated. Within the extracolonic manifestations of FAP are the maxillofacial, such as: osteomas and dental alterations, which may precede the development of colonic polyposis. Although studies of colonic adenomatous polyposis and colon cancer exist in Chile, there are few reports of maxillofacial manifestations in these patients. In the family under study, previously described manifestations were found, such as: odontoma, osteomas and dental malformations; mucosal tags were also observed, with no previous association with the syndrom.

Síndromes de neoplasia endocrina múltiple: revisión radiológica / Multiple Endocrine Neoplasia Syndromes: Radiological Review

Los síndromes de neoplasia endocrina múltiple (MEN), incluyen una serie de enfermedades con alteraciones genéticas que se caracterizan por la presencia de tumores que afectan a dos o más glándulas endocrinas. Son síndromes con una herencia autosómica dominante e incluyen tres patrones: MEN 1 (síndrome de Wermer), MEN 2 (que incluye MEN 2A o síndrome de Sipple y MEN 2B o síndrome de Wagenmann-Froboese) y MEN 4. Los adenomas paratiroideos y el carcinoma medular tiroideo, son los tumores más frecuentes del MEN tipo 1 y 2 respectivamente. Esos síndromes son más comunes en pacientes jóvenes, con patología de afectación bilateral, múltiple o multifocal y, sobre todo, en pacientes con antecedentes familiares. Es necesario el trabajo en equipo de endocrinólogos, cirujanos, oncólogos y radiólogos para optimizar el tratamiento de esos pacientes.

Multiple endocrine neoplasia (MEN) encompasses a serial of familial genetically disorders in wich tumors simultaneusly occur in two or more endocrine organs. MEN síndromes are autosomal-dominant disorders categorized into three main patterns: MEN 1 (Wermer syndrome), MEN 2 (includes MEN 2A o Sipple syndrome and MEN 2B o Wagenmann-Froboese syndrome) and MEN 4. Parathyroid adenomas and medullary thyroid carcinoma are the most frecuent tumors in MEN 1 and MEN 2 respectively. These entities will be suspected in younger patients, bilateral, multiple or multifocal disease and, specially, in patients with family background. Cooperation between endocrinologist, surgeons, oncologists and radiologists is pivotal for optimizing patient treatment.

Efficacy and Long-Term Safety of Everolimus in Pancreatic Neuroendocrine Tumor Associated with Multiple Endocrine Neoplasia Type I: Case Report.

BACKGROUND: Approximately 10% of pancreatic neuroendocrine tumors (NET) are associated with familial syndromes, with the most common type being multiple endocrine neoplasia type 1 (MEN-1). However, the available evidence on how to treat NET comes from studies in sporadic NET. CASE REPORT: Here we report the case of a 51-year-old male patient with a metastatic MEN-1-associated pancreatic NET and hypercalcemia related to primary hyperparathyroidism and tumor-secreted parathyroid-related protein. The patient was treated with everolimus, and showed complete resolution of hypercalcemia and tumor control for 3 years when he presented with pulmonary cryptococcosis and disease progression. CONCLUSION: This case report describes the activity of everolimus in a patient with MEN-1-associated pancreatic NET, its efficacy in treating malignant hypercalcemia associated with NET and the risk of opportunistic infections with prolonged use of this agent.

Síndrome de Zollinger-Ellison: revisión del conocimiento actual / Zollinger-Ellison syndrome: review of current knowledge

El síndrome de Zollinger-Ellison se caracteriza por la presencia de úlceras pépticas resistentes al tratamiento que se deben a la hipersecreción ectópica de gastrina por un tumor neuroendocrino, que es el gastrinoma y que resulta en la hipersecreción de ácido clorhídrico en el estómago. Este síndrome se presenta en forma esporádica y también se asocia al síndrome de neoplasia neuroendocrina múltiple de tipo 1. Se describen ambas presentaciones clínicas, así como también la fisiopatología, el diagnóstico, el estudio, el tratamiento y el pronóstico, enfatizando en los detalles técnicos de la cirugía. El pronóstico de los gastrinomas cuando son identificados precozmente es bueno, aun en aquellos casos malignos, por lo que la sospecha clínica asociada al estudio específico y al tratamiento de estos pacientes es fundamental. Dada la tecnología diagnóstica disponible en la actualidad, la identificación de estos tumores será cada vez más frecuente, por lo que el conocimiento de los detalles esenciales para su tratamiento es importante para el cirujano.

Zollinger-Ellison syndrome is characterized by peptic ulcers refractory to treatment secondary to ectopic gastrin hypersecretion by a neuroendocrine tumor called gastrinoma resulting in gastric hydrochloride acid hypersecretion. This syndrome occurs sporadically and is also associated to Multiple Neuroendocrine Neoplasia type 1. The present article describes their clinical presentations, as well as their pathophysiology, diagnosis, study, treatment and prognosis, emphasizing the surgical technical details. Early diagnosis of gastrinoma carries a good prognosis, even in those malignant cases. Consequently, clinical suspicion associated to specific study leading to diagnosis and treatment is fundamental for these patients. Due to the available current technology, the diagnosis of these tumors should be more common, as a consequence the knowledge of important details within their management is important for the surgeon.

Síndrome de zolinger - Elison / Syndrome of Zolinger - Elison

Resumen:El síndrome de Zollinger - Ellison es una endocrinopatía que fue descrita en 1955 por los doctores Robert Zollinger y Edwin Ellison, quienes propusieron la triada diagnóstica que incluye hipersecreción gástrica ácida, úlcera péptica y gastrinoma. Esta enfermedad predomina en mujeres entre los 50 y 60 años de edad. Según su etiología, este síndrome se clasifica en una forma esporádica o asociada a neoplasia endocrina múltiple tipo 1 (NEM - 1).Más de la mitad de los gastrinomas se localizan en la pared duodenal, el páncreas es la segunda ubicación en frecuencia. Existen localizaciones ectópicas en ovario, mesenterio, hígado y ducto biliar. A nivel histopatológico se encuentran células tumorales redondas, con núcleos pequeños y nucléolos prominentes. La hipersecreción ácida gástrica está asociada a un defecto en la inhibición del retrocontrol negativo de la somatostatina sobre las células G antrales productoras de gastrina. Clínicamente, los pacientes manifiestan dolor abdominal, diarrea, pirosis, náuseas y vómitos; relacionados principalmente a la formación de úlceras pépticas. El diagnóstico debe incluir una medición en los niveles séricos de gastrina y valores de pH gástrico. El tratamiento de primera línea es la terapia antisecretora, principalmente con inhibidores de la bomba de protones. Los estudios de imágenes son deutilidad para detectar metástasis y evaluar la enfermedad quirúrgicamente resecable. Se debe hacer diagnóstico diferencial con otros tumores neuroendocrinos y causas de hipergastrinemia.

Abstract:Zollinger - Ellison syndrome is an endocrinopathy that was first described in 1955 by doctors Robert Zollinger and Edwin Ellison, who proposed the diagnostic triad that includes gastric acid hypersecretion, peptic ulcer and gastrinoma. This disease predominates in women between 50 and 60 years old. Based on the etiology, the syndrome is classified in sporadic or associated with multiple endocrine neoplasia type 1 (NEM - 1). Over half of gastrinomas are located in the duodenal wall, the pancreas is the second frequency location. There are ectopic locations, such as ovary, mesentery, liver and bile duct. Round cells, small nuclei and prominent nucleoli, are the main hispathologycal characteristics. Gastric acid hypersecretion is associated with a defect in the negative feedback inhibition of somatostatin on G antral gastrin-producing cells. Clinically, patients present abdominal pain, diarrhea, heartburn, nausea and vomiting; primarily related to the development of peptic ulcers. Diagnosis includes a measurement in serum gastrin levels and gastric pH values. The first line treatment is the antisecretory therapy, primarily proton-pump inhibitor. Imaging studies are useful to detect metastases and evaluate the surgically resectable disease. Neuroendocrine tumors and hypergastrinemia causes are the main differential diagnoses, the clinician should consider.

Complexo de Carney esporádico com tumor testicular e mixoma atrial: relato de caso / Sporadic Carney complex with testicular tumor and atrial myxoma: case report

O complexo de Carney é uma rara forma de neoplasia endócrina múltipla familial autossômica dominante. Está associado à alteração de pigmentação cutânea e mucosa, doença nodular adrenal pigmentosa primária, mixomas cardíacos e cutâneos, adenomas hipofisários funcionantes, neoplasia testicular, adenoma ou carcinoma de tireoide, além de cistos ovarianos. Aproximadamente 70% dos indivíduos diagnosticados com complexo de Carney têm pais afetados, e 30% apresentam forma esporádica. O objetivo deste estudo foi relatar um caso de complexo de Carney esporádico por mixoma cardíaco e tumor testicular. Ressalta-se a importância do caso por sua raridade e sua forma curiosa de apresentação. Homem, 33 anos, manifestou dois quadros de acidentes vasculares cerebrais em 4 meses. Na investigação apresentou pressão arterial elevada com sopro sistólico discreto e fraqueza muscular (força grau 4 em membro superior direito e grau 3 em membro inferior direito). História mórbida de tumor testicular de células de Sertoli há 7 anos com orquiectomia bilateral. História familiar sem particularidades. Na investigação, evidenciaram-se sobrecarga atrial esquerda ao eletrocardiograma e massa tumoral pedunculada compatível com mixoma atrial esquerdo ao ecocardiograma transesofágico. Foi configurada síndrome de Carney pela presença de dois critérios maiores, e o paciente foi submetido à atriotomia esquerda, com ressecção da massa tumoral e confirmação anatomopatológica. A curiosa apresentação do caso recorda que, diante de um caso de acidente vascular cerebral em paciente jovem, a suspeita clínica seja direcionada a causas mais raras. O complexo de Carney esporádico é raro, dificultando ainda mais a elucidação.

Carney complex is a rare form of autosomal dominant multiple endocrine neoplasia familial. Changing skin pigmentation and mucos, primary pigmented nodular adrenal disease, cardiac and cutaneous myxomas, functioning pituitary adenomas, testicular cancer, thyroid adenoma or carcinoma is associated, and ovarian cysts. Approximately 70% of individuals diagnosed with Carney complex have affected parents and 30% have sporadically. The aim of this study was to report a case of sporadic Carney complex due to cardiac myxoma and testicular tumor. We emphasized the importance of the case for its rarity and curious form of presentation. Man, 33, showed two episodes of strokes in 4 months. In research presented high blood pressure with mild systolic murmur and muscle weakness (grade 4 strengthin the right arm and grade 3 in the right lower limb). Morbid history of testicular Sertoli cell tumor 7 years ago with bilateral orchiectomy. No special family history. On investigation, left atrial enlargement and was evident on the electrocardiogram, and transesophageal echocardiogram revealed the presence of pedunculated tumor mass setting a left atrial myxoma. Carney's syndrome was characterized by the existence of two major criteria and patient underwent left atriotomy with resection of the tumor mass and anatomic-pathologic confirmation. The curious case presentation reminded us that before a case of stroke in a young patient should direct the clinical suspicion for rarer causes. The Carney complex sporadic is rare, yet difficult to elucidate.

Tumor neuroendócrino pancreático metastásico, caso clínico / Metastatic pancreatic neuroendocrine tumor: clinical case

Introducción: los insulinomas son tumores neuroendocrinos pancreáticos secretores de insulina, la incidencia en la población en general estimada es de 1 a 4 casos en un millón de habitantes por año. Los insulinomas constituyen el 60% de los tumores de páncreas, de los cuales el 90% son benignos y únicos; el 10% son múltiples, la mayoría asociados a MEN 1 (Neoplasia Endocrina Múltiple) y del 5 al 10% son malignas. La posibilidad de recidiva obliga a un diagnóstico y seguimiento a largo plazo. La característica clínica del insulinoma es la hipoglucemia en ayunas, con signos y síntomas de neuroglucopenia, que pueden estar precedidos o no por manifestaciones adrenérgicas. El tratamiento de elección es el quirúrgico; en etapas irresecables o avanzadas se proponen tratamientos paliativos o sintomáticos con quimioterapia o procedimientos mediante radiología intervencionista con pobres respuestas. Se ha demostrado que con nuevos tratamientos con inhibidores de la tirosina kinasa e inhibidores de la vía de la rapamicina en tumores neuroendocrinos pancráticos bien diferenciados las respuestas tanto en sobrevida libre de progresión así como sobrevida global mejoran importantemente. Caso: presentamos el caso de un hombre de 44 años, con diagnóstico de insulinoma y MEN 1, debutó con convulsiones tónico clónicas generalizadas tratado con pancreatectomia parcial, siete años más tarde, tras haber permanecido asintomático nuevo episodio de convulsiones, documentándose hipoglicemias severas y múltiples metástasis hepáticas, sometido a una pancreatoduodenectomia y como tratamiento sintomático recibió corticoides en altas dosis, diazóxido, octreotide mensual y dos líneas de quimioterapia, además de embolización de las metástasis hepáticas de mayor tamaño y por progresión de enfermedad se inició inhibidores de tirosin-kinasa por un período de tres meses y el paciente fallece.

Introduction: the Insulinomas are pancreatic neuroendocrine tumors secreting insulin. The incidence in the general population is estimated 1-4 per 1 000 000 yearly Insulinoma accounts for 60% of pancreatic tumors, of which 90% are benign and unique, 10% are multiple, mostly associated with MEN 1 (Multiple Endocrine Neoplasia), and 5-10% is malignant. The possibility of recurrence requires diagnosis and long-term monitoring. The clinical characteristic of insulinoma is fasting hypoglycemia, with signs and symptoms of neuroglucopenia, which may be preceded or not by adrenergic manifestations. Surgery is the treatment of choice, in irrsecable; and in advanced stages the proposed palliatives or symptomatic treatments are with chemotherapy or procedures through interventional radiologist with poor responses. It has been shown that new treatments with inhibitors of tyrosine kinase inhibitors and rapamycin pathway for pancreatic neuroendocrine well differentiated tumors, the response in both progression-free survival and overall survival signifcantly improved. Case study: we report the case of a 44 year old male of, diagnosed with insulinoma and MEN 1, debuted with tonic clonic seizures treated with partial pancreatectomy, 7 years later after a new episode of seizures documented severe hypoglycemia and multiple liver metastases, underwent a pancreatoduodenectomy and as symptomatic treatment received high-dose corticosteroids, diaxozido, octreotide monthly and 2 lines of chemotherapy, in addition to embolization of the larger liver metastases masses, and due to disease progression tyrosine kinase inhibitors was initiated for a period of 3 months and the patient dies.

Factors associated with reporting of abuse against children and adolescents by nurses within Primary Health Care / Fatores associados à notificação de maus-tratos em crianças e adolescentes realizada por enfermeiros na Atenção Primária à Saúde / Factores asociados a la notificación del maltrato en niños y adolescentes realizada por enfermeros en la Atención Primaria a la Salud

OBJECTIVE: to analyze the factors associated with the underreporting on the part of nurses within Primary Health Care of abuse against children and adolescents. METHOD: cross-sectional study with 616 nurses. A questionnaire addressed socio-demographic data, profession, instrumentation and knowledge on the topic, identification and reporting of abuse cases. Bivariate and multivariate logistic regression was used. RESULTS: female nurses, aged between 21 and 32 years old, not married, with five or more years since graduation, with graduate studies, and working for five or more years in PHC predominated. The final regression model showed that factors such as working for five or more years, having a reporting form within the PHC unit, and believing that reporting within Primary Health Care is an advantage, facilitate reporting. CONCLUSION: the study's results may, in addition to sensitizing nurses, support management professionals in establishing strategies intended to produce compliance with reporting as a legal device that ensures the rights of children and adolescents. .

Cognitive behavioural therapy for depression in multiple endocrine neoplasia type IIB: a 1-year follow-up.

This case report describes a 24-year-old man diagnosed with multiple endocrine neoplasia type IIB and major depression. Because cognitive behavioural therapy (CBT) has proven effective in the treatment of major depression in the general population and patients with cancer, we decided to adapt and use this therapy and evaluate its impact on major depression and the patient's quality of life. The therapy was conducted individually in 15 sessions that were given over a span of 25 weeks. The data show that therapy was a useful treatment that reduced depression according to the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria and self-report instruments. CBT also helped improve the patient's quality of life, and it was considered to be an acceptable intervention for the patient, with ongoing positive results 1 year after the last psychotherapy session. CBT is a potential option for treating depression in this population but further research is needed.

A differential diagnosis of inherited endocrine tumors and their tumor counterparts.

Inherited endocrine tumors have been increasingly recognized in clinical practice, although some difficulties still exist in differentiating these conditions from their sporadic endocrine tumor counterparts. Here, we list the 12 main topics that could add helpful information and clues for performing an early differential diagnosis to distinguish between these conditions. The early diagnosis of patients with inherited endocrine tumors may be performed either clinically or by mutation analysis in at-risk individuals. Early detection usually has a large impact in tumor management, allowing preventive clinical or surgical therapy in most cases. Advice for the clinical and surgical management of inherited endocrine tumors is also discussed. In addition, recent clinical and genetic advances for 17 different forms of inherited endocrine tumors are briefly reviewed.

The early diagnosis of patients with inherited endocrine tumors may be performed either clinically or by mutation analysis in at-risk individuals. Early detection usually has a large impact in tumor management, allowing preventive clinical or surgical therapy in most cases. Advice for the clinical and surgical management of inherited endocrine tumors is also discussed. In addition, recent clinical and genetic advances for 17 different forms of inherited endocrine tumors are briefly reviewed.

Feocromocitoma asintomático / Asymptomatic pheochromocytoma

El feocromocitoma es un tumor que produce catecolaminas,mayor responsable de la hipertensión arterial en jóvenes,con mayor frecuencia se localiza en la medula suprarrenal, unilateral.Generalmente asociado con neoplasia endócrina múltiple.Los pacientes presentan una serie de síntomas, entre ellosla hipertensión arterial.Se presenta el caso de una paciente de 31 años, con doloren hipocondrio derecho de un año de evolución, tipo pesadezy pérdida de peso de 3 kg. Al examen físico se constató tumoraciónen hipocondrio derecho que llega a epigastrio, de 12cm de diámetro. Con el diagnóstico de tumor retroperitonealobtenido por imágenes se decide una laparotomía exploradoradonde se visualizó un tumor de 18cm. de diámetro, sólido, enpolo superior del riñón derecho, adherido a vena cava. Se realizóuna exéresis tumoral y el informe de anatomía patológicaconfirmó feocromocitoma

Narrowing the gap of personalized medicine in emerging countries: the case of multiple endocrine neoplasias in Brazil.

The finished version of the human genome sequence was completed in 2003, and this event initiated a revolution in medical practice, which is usually referred to as the age of genomic or personalized medicine. Genomic medicine aims to be predictive, personalized, preventive, and also participative (4Ps). It offers a new approach to several pathological conditions, although its impact so far has been more evident in mendelian diseases. This article briefly reviews the potential advantages of this approach, and also some issues that may arise in the attempt to apply the accumulated knowledge from genomic medicine to clinical practice in emerging countries. The advantages of applying genomic medicine into clinical practice are obvious, enabling prediction, prevention, and early diagnosis and treatment of several genetic disorders. However, there are also some issues, such as those related to: (a) the need for approval of a law equivalent to the Genetic Information Nondiscrimination Act, which was approved in 2008 in the USA; (b) the need for private and public funding for genetics and genomics; (c) the need for development of innovative healthcare systems that may substantially cut costs (e.g. costs of periodic medical followup); (d) the need for new graduate and postgraduate curricula in which genomic medicine is emphasized; and (e) the need to adequately inform the population and possible consumers of genetic testing, with reference to the basic aspects of genomic medicine.

MENX and MEN4.

Multiple endocrine neoplasias are autosomal dominant disorders characterized by the occurrence of tumors in at least two endocrine glands. Two MEN syndromes have long been known and are well characterized: the MEN type 1 (MEN1) and type 2 (MEN2). These syndromes are caused by germline mutations in the MEN1 and RET genes, respectively, and have a different tumor spectrum. Recently, a variant of the MEN syndromes arose spontaneously in a rat colony and was named MENX. Affected animals consistently develop multiple endocrine tumors, with a spectrum that shares features with both MEN1 and MEN2 human syndromes. Genetic studies identified a germline mutation in the Cdkn1b gene, encoding the p27 cell cycle inhibitor, as the causative mutation for MENX. Capitalizing on these findings, heterozygous germline mutations in the human homologue, CDKN1B, were searched for and identified in patients with multiple endocrine tumors. As a consequence of this discovery, a novel human MEN syndrome, named MEN4, was recognized, which is caused by mutations in p27. Altogether, these studies identified Cdkn1b/CDKN1B as a novel tumor susceptibility gene for multiple endocrine tumors in both rats and humans. Here we review the characteristics of the MENX and MEN4 syndromes and we briefly address the main function of p27 and how they are affected by MENX/4-associated mutations.
