Chromoscopy-Guided Endomicroscopy Increases the Diagnostic Yield of Intraepithelial Neoplasia in Ulcerative Colitis
2007
Background & Aims: Because of the large number of biopsy specimens, surveillance colonoscopy in ulcerative colitis (UC) is currently time consuming and significant flat lesions still may be missed. In this study we assessed the value of combined chromoscopy and endomicroscopy for the diagnosis of intraepithelial neoplasias in a randomized controlled trial. Methods: A total of 161 patients with long-term UC in clinical remission were randomized at a 1:1 ratio to undergo conventional colonoscopy or chromoscopy with endomicroscopy. Eight patients were excluded because of insufficient bowel preparation. In the conventional colonoscopic group (n = 73), random biopsy examinations and targeted bio…
Medullary thyroid carcinoma in a 2-month-old male with multiple endocrine neoplasia 2B and symptoms of pseudo-Hirschsprung disease: a case report
2007
A 5-week-old male patient was seen for symptoms suggestive of Hirschsprung disease (abdominal distension, failure to thrive, and explosive defecation). Rectum biopsies revealed an intestinal ganglioneuromatosis, which is usually associated with multiple endocrine neoplasia (MEN) syndrome type 2B. The ensuing molecular genetic analysis revealed a M918T mutation of the RET protooncogene, which is associated with early-onset medullary thyroid carcinoma (MTC). Therefore, total thyroidectomy and central lymphadenectomy were performed at the age of 9 weeks. Histology showed a medullary microcarcinoma. This report of MTC occurrence within the first weeks of life underlines the importance of early …
Edad, creencias de salud y asistencia a un programa de cribado mamográfico en la comunidad valenciana
2004
Yolanda Andreu Vaillo, Mª José Galdón Garrido, Estrella Durá Ferrandis, Stephanie Carretero Gómez (yolanda.andreu@uv.es) La edad influye significativamente en las creencias de salud relacionadas con la asistencia a programas de cribado mamográfico. El objetivo de este trabajo es analizar las creencias y actitudes hacia el cáncer de mama asociadas a la asistencia a un programa de cribado en diferentes grupos de edad.Métodos: Utilizando un diseño transversal se comparan las creencias de salud de un grupo de mujeres que acuden a un programa de cribado con las de las mujeres que no lo hacen, considerando tres intervalos de edad: menores de 50 años (N=279), 50-60 años (N=463), mayores de 60 (N=2…
Vulvar cancer: a review for dermatologists.
2015
Vulvar malignancies are important tumors of the female reproductive system. They represent a serious health issue with an incidence between 2 and 7 per 100,000 and year. We provide a review about most important cancer entities, i.e., melanoma, squamous cell carcinoma, basal cell carcinoma, neuroendocrine cancer, and skin adnexal malignancies. Squamous cell carcinoma is the most common vulvar malignancy that can develop from vulvar intraepithelial neoplasia or de novo. Basal cell carcinoma represents only 2 % of all vulvar cancers. Melanoma of the vulva exists in two major types—superficial spreading and acral lentiginous. A special feature is the occurrence of multiple vulvar melanomas. Of …
Complicaciones infecciosas en el trasplante de sangre de cordón umbilical de donante no emparentado en adultos con enfermedades hematológicas malignas
2019
El trasplante de sangre de cordón umbilical (TSCU) es una opción terapéutica con potencial curativo para pacientes con enfermedades hematológicas malignas u otras enfermedades con grave afectación de la hematopoyesis que carecen de un donante familiar idéntico y precisan ser trasplantados en un breve plazo. Sin embargo, una de las principales limitaciones del TSCU es la importante morbilidad y mortalidad infecciosa que se observa con este procedimiento. Un detallado conocimiento del perfil clínico y microbiológico de las infecciones que desarrollan los pacientes sometidos a un TSCU es una condición necesaria para tratar de disminuir su impacto en la morbilidad y mortalidad. Así, el análisis…
Burkitt lymphoma with a granulomatous reaction: an M1/Th1‐polarised microenvironment is associated with controlled growth and spontaneous regression
2021
Aims Burkitt lymphoma (BL) is an aggressive B-cell lymphoma that, in some instances, may show a granulomatous reaction associated with a favourable prognosis and occasional spontaneous regression. In the present study, we aimed to define the tumour microenvironment (TME) in four such cases, two of which regressed spontaneously. Methods and results All cases showed aggregates of tumour cells with the typical morphology, molecular cytogenetics and immunophenotype of BL surrounded by a florid epithelioid granulomatous reaction. All four cases were Epstein-Barr virus (EBV)-positive with type I latency. Investigation of the TME showed similar features in all four cases. The analysis revealed a p…
The diagnostic possibilities of Positron Emission Tomography (PET)
2014
Se describen los principios de la tomografía por emisión de positrones (PET) como procedimiento diagnóstico de reciente introducción en el campo de las Ciencias de la Salud. Las aplicaciones clínicas principales se dan en un grupo concreto de especialidades: la cardiología, neurología, psiquiatría y sobre todo la oncología. La tomografía por emisión de positrones es una técnica de diagnóstico por la imagen no invasiva de uso clínico. Se trata de una excelente herramienta para el estudio de la estadificación y la posible malignización de los tumores de cabeza y cuello, la detección de metástasis y linfoadenopatías no valorables clínicamente, así como para el diagnóstico de recidivas tumorale…
Prädiktive genetische Untersuchungen: Individualisierung von Diagnostik und Therapie bei Familien mit multipler endokriner Neoplasie Typ II
2008
BACKGROUND AND OBJECTIVE When multiple endocrine neoplasia type 2 (MEN2) is suspected, genetic tests are at the centre of screening procedures. It was the aim of this study to compare the diagnostic value of molecular biological investigations with that of conventional biochemical tests. PATIENTS AND METHODS The study cohort consisted of all 144 patients cared for in our department since 1990 with the suspected diagnosis of MEN2 (evidence of a medullary thyroid carcinoma [MTC]), coexistence of two MEN2 tumours or a family history of MEN2. 14 of the 144 patients (from 12 families) were already known to have an hereditary MTC, while the remaining 130 had been referred for further diagnostic i…
MEN1 Disease Occurring Before 21 Years Old: A 160-Patient Cohort Study From the Groupe d'étude des Tumeurs Endocrines
2015
Multiple endocrine neoplasia Type-1 (MEN1) in young patients is only described by case reports.To improve the knowledge of MEN1 natural history before 21 years old.Obtain a description of the first symptoms occurring before 21 years old (clinical symptoms, biological or imaging abnormalities), surgical outcomes related to MEN1 Neuro Endocrine Tumors (NETs) occurring in a group of 160 patients extracted from the "Groupe d'étude des Tumeurs Endocrines" MEN1 cohort.The first symptoms were related to hyperparathyroidism in 122 cases (75%), pituitary adenoma in 55 cases (34%), nonsecreting pancreatic tumor (NSPT) in 14 cases (9%), insulinoma in 20 cases (12%), gastrinoma in three cases (2%), mal…
Primary multifocal anaplastic large cell lymphoma with eyelid involvement: a case report
2019
ABSTRACT Ocular adnexal involvement in CD30+ lymphoproliferative disorders is rare. We report the case of a 73-year-old woman with a relapsing primary cutaneous anaplastic large cell lymphoma on her eyelid. A systemic extension study excluded extracutaneous involvement. Systemic chemotherapy resulted in an optimal response, with complete regression of the cutaneous lesions. There has been no recurrence during the 2 years of follow-up. RESUMO O acometimento ocular adicional nos distúrbios linfoproliferativos CD30+ é raro. Relatamos o caso de uma mulher de 73 anos com linfoma de grandes células anaplásicas primárias recidivantes em sua pálpebra. A avaliação sistêmica excluiu envolvimento extr…
