ABSTRACT

OBJECTIVE: To determine whether medical history, clinical examination and human papilloma virus (HPV) genotype influence spontaneous regression in cervical intraepithelial neoplasia grade I (CIN-I). MATERIAL AND METHODS: We retrospectively evaluated 232 women who were histologically diagnosed as have CIN-I by means of Kaplan-Meier curves, the pattern of spontaneous regression according to the medical history, clinical examination, and HPV genotype. RESULTS: Spontaneous regression occurred in most patients and was influenced by the presence of multiple HPV genotypes but not by the HPV genotype itself. In addition, regression frequency was diminished when more than 50% of the cervix surface was affected or when an abnormal cytology was present at the beginning of follow-up. CONCLUSION: The frequency of regression in CIN-I is high, making long-term follow-up and conservative management advisable. Data from clinical examination and HPV genotyping might help to anticipate which lesions will regress.

ABSTRACT

Introducción. La punción aspiración con aguja fina (PAAF) es un procedimiento diagnóstico mínimamente invasivo y extremadamente útil para tipificar lesiones. La limitación de medios en las prácticas de anatomía patológica ha dificultado su enseñanza. Describimos la incorporación de maniquíes diseñados para realizar PAAF en nuestro centro. Material y métodos. Los maniquíes consisten en 2 simuladores de tareas, artesanales y a tamaño natural, de las regiones facial/cervical (modelo de utilidad U201500372) y de torso, respectivamente, revestidos por silicona, simulando piel, con áreas tumorales. Permiten realizar PAAF (palpación, punción, aspiración, obtención de material y extensión sobre portaobjetos) y son reutilizables. La práctica se realizó durante 3 cursos académicos (2013-2016) y consistió en realizar PAAF de manera individualizada sobre contexto clínico, con ulterior correlación citológica. Resultados. Un total de 178 estudiantes de medicina de la Universidad de Murcia de tercer curso realizaron la práctica (28 grupos: 105 mujeres, 73 hombres). La tasa de acierto (punción, aspiración de material y extensión en portaobjetos) fue del 97,2% con la primera punción. Además, 13 estudiantes procedentes de otras 10 universidades (nacionales e internacionales) llevaron a cabo la práctica, refiriendo la no existencia en sus centros de procedencia. Fue considerada como de gran valor sobre encuesta anónima. Discusión. Las prácticas de PAAF son fácilmente implementables y potencialmente incorporables a los formatos evaluativos tipo examen clínico objetivo estructurado (ECOE). No existe una adecuada estandarización en las prácticas de diferentes centros universitarios. Las prácticas de PAAF mejoran la formación del estudiante y proporciona un mayor conocimiento y una mejor consideración de nuestra especialidad (AU)


Background. Fine needle aspiration cytology (FNAC) is a minimally invasive and extremely useful procedure. The characteristics of the practice of pathology, together with limited equipment, make teaching this technique difficult. We therefore have introduced phantoms designed to perform FNAC as part of the medical education programme in our hospital. Material and methods. Phantoms are two life-sized hand-made reproductions of an adult head & neck (utility model ES1140059) and a trunk, respectively, coated with silicone simulating skin and with inserted tumor areas. They allow the whole FNAC process (palpation, puncture, aspiration, placement of material on slide and smear preparation) to be performed and, furthermore, are reusable. During 3 academic years (2013-2016) FNAC samples have been obtained in this way by each student individually, in a clinical context and with subsequent cytological correlation. Results. A total of 178 third year medical students from the University of Murcia, Spain, took part in the FNAC training programme (28 groups: 105 women, 73 men). The success rate in the first attempt (puncture, aspiration of material, placing and extending the obtained material on slides) was 97.2%. Furthermore, 13 students from 10 other universities (national and international) also took part, not having such a programme in their medical schools. In an anonymous survey the consensus was that it was valuable practical training. Discussion. Training in FNAC techniques is easy to include in the undergraduate curriculum and also in the Objective Structured Clinical Examination (OSCE) evaluation format. There is no proper standardization in training among different universities. FNAC simulation provides students with greater knowledge and appreciation of our specialty (AU)

ABSTRACT

Introducción: En la literatura científica se han publicado resultados contradictorios sobre el valor pronóstico de la pérdida de la expresión del antígeno de grupo sanguíneo A (GSA) en el cáncer de pulmón, por lo que analizamos retrospectivamente este hecho en nuestra serie quirúrgica. Pacientes y métodos. En un estudio multicéntrico de 402 pacientes con carcinoma no microcítico de pulmón (CNMP) en estadio I patológico según la nueva clasificación TNM-2009 se analizó la influencia pronóstica de la pérdida de la expresión del antígeno del GSA en los 209 pacientes con grupos sanguíneos A o AB. Resultados: La supervivencia a los 5 años de los pacientes en estadio I patológico que mantenían la expresión del antígeno del GSA fue del 73%, frente a una supervivencia del 53% en los pacientes que habían perdido la expresión del mismo (p=0,03). Cuando se analizó la supervivencia subdividiendo la muestra en estadios IA y IB, solo se alcanzó la significación estadística en el estadio IA (p=0,038). Al analizar la supervivencia según el tipo histológico, los pacientes con adenocarcinoma que perdían la expresión del antígeno del GSA tenían una menor supervivencia, con una p estadísticamente muy significativa (p=0,003). El análisis multivariable mostró que la edad, el género y la expresión del antígeno del GSA eran factores pronósticos independientes. Conclusiones: La pérdida de la expresión del antígeno del grupo sanguíneo A tiene una influencia pronóstica negativa en el CNMP estadio I patológico, sobre todo en el tipo histológico adenocarcinoma(AU)


Introduction: In the scientific literature, contradictory results has been published on the prognostic value of the loss of expression of blood group antigen A (BAA) in lung cancer. The objective of our study was to analyze this fact in our surgical series. Patients and methods: In a multicenter study, 402 non-small-cell lung cancer (NSCLC) patients were included. All were classified as stage-I according to the last 2009-TNM classification. We analyzed the prognostic influence of the loss of expression of BAA in the 209 patients expressing blood group A or AB. Results: The 5-year cumulative survival was 73% for patients expressing BAA vs 53% for patients with loss of expression (P=.03). When patients were grouped into stages IA and IB, statistical significance was only observed in stage I-A (P=.038). When we analyzed the survival according to histologic type, those patients with adenocarcinoma and loss of expression of BAA had a lower survival rate that was statistically very significant (P=.003). The multivariate analysis showed that age, gender and expression of BAA were independent prognostic factors. Conclusions: The loss of expression of blood group antigen A has a negative prognostic impact in stage I NSCLC, especially in patients with adenocarcinoma(AU)

ABSTRACT

La telepatología es la transmisión de imágenes digitales de anatomía patológica por sistemas de telecomunicación, y con fines de consulta, diagnóstico, investigación, o docencia. La telepatología estática utiliza imágenes fijas, mientras que la dinámica se basa en el envió de imágenes obtenidas mediante videocámara. La telepatología estática comienza con la selección por un patólogo de las imágenes demostrativas de una lesión. Posteriormente las imágenes deben ser procesadas y comprimidas, lo que permite mejorar su calidad diagnóstica y, fundamentalmente su tamaño, para que puedan ser enviadas de forma efectiva por vías de comunicación con anchos de banda limitados. En este artículo se analizan todas estas etapas y sus aspectos técnicos. En la actualidad, la telepatología estática cuenta con un papel dentro de la patología diagnóstica, aunque este papel es todavía limitado. En otros campos, como la docencia, foros de discusión y consulta de imágenes de casos, la telepatología estática cuenta con una amplia aceptación (AU)
