[Times and conditions of storage of samples in anatomic pathology. Recommendations of the Spanish Society of Anatomic Pathology (SEAP) part 1: samples for diagnosis]. / Tiempos y condiciones de almacenamiento de las muestras en anatomía patológica. Recomendaciones de la Sociedad Española de Anatomía Patológica parte 1: muestras destinadas al diagnóstico.

INTRODUCTION: The correct storage of specimens in the Pathology service is of vital importance for patient safety. However, there are no clear recommendations as regarding how long samples should be stored for a minimum period. MATERIAL AND METHODS: A working group of the Spanish Society of Anatomic Pathology has reviewed a series of recommendations established in the literature and after two rounds of consultations and a discussion and voting phase has established a series of storage time proposals. RESULTS: Each of the proposals is presented with the data found in the literature and sometimes offers definitions and exceptions to the proposal. CONCLUSION: These recommendations, which are minimums, establish a period of at least 10 years for paraffin embedded blocks (including cell blocks), histological preparations, general cytology, pathologic cervico-vaginal cytology and electron microscopy blocks; at least 3 years for cervico-vaginal cytology, 5 years for extracted nucleic acids, at least 4 weeks for tissue in formalin and from the time of diagnosis for liquid cytology material and fluids.

[SEAP-IAP recommendations for the collection, storage and use of biological materials of human origin and related data intended for research. Generic biobank consideration and ethical-legal review (Part II)]. / Recomendaciones de la SEAP-IAP para la recolección, el almacenamiento y el uso de materiales biológicos de origen humano y los datos relacionados, destinados a la investigación. Consideración genérica de biobanco y revisión ético-legal (Parte II).

The working group set up by the SEAP-IAP addresses in this Part II some general considerations and five particular considerations to be taken into account when a biological sample of human origin, coming from our archives, acquires a different destination from the usual one, in this case for research. From this moment on, we must follow mandatory legal and ethical rules, and the different recitals provide us with guidelines to ensure good practice, both for biological material and its associated data. The traditional task of custody given to the Pathological Anatomy is approached, as always, from the point of view of responsibility and, in this article, adjusted to its time.

Comparative study of the prevalence of the human papilloma virus in Spanish and foreign women participating in a population screening programme in Castilla y León. / Estudio comparativo de la prevalencia de virus de papiloma humano en las mujeres españolas y extranjeras, participantes en un programa de cribado poblacional en Castilla y León.

INTRODUCTION: The objective of this study was to compare the prevalence of human papilloma virus (HPV) in Spanish and foreign women in a cervical cancer screening programme of Castilla y León and foreign women living in the community who participated in the programme. METHODS: This was an observational, descriptive, cross - sectional, retrospective study of period prevalence. The sample consisted of all the women included in the cervical cancer prevention programme of the Regional Ministry of Health of the Junta de Castilla y León who were screened for cervical cancer during the period from 2012 to 2014, aged between 25 and 64 years of age. RESULTS: Of the 190,203 cervical smear samples collected, 10.2% were foreign (n=19,329). The prevalence of HPV in the foreign women was 23.51%, significantly higher than in the Spanish women (P<.001). The presence of morphological and microbiological changes in the foreign women was also greater. CONCLUSIONS: This study makes an important contribution, since it comprised a voluminous population screening sample. The prevalence of HPV in the foreign women was significantly higher than in the women born in Spain. It is important to continue studying this type of population, who are difficult to recruit for cultural reasons.
