[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)].

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.

Atypical double colorectal metastasis: spleen and uterus.

Oligometastatic disease is a relatively new concept that refers to an intermediate stage between disseminated and localized cancer. Most frequent locations for colorectal metastasis are lung and liver. We present an a typical case of an 85-year-old woman who was diagnosed with a low-grade adenocarcinoma in left colon; she underwent a left laparoscopic hemicolectomy which resulted in a stage IIIb.

Predictors of Metachronous Risk Polyps After Index Colonoscopy.

Introduction: Guidelines for surveillance after polypectomy are lacking in strong evidence. Our aim was to identify some precursors of colorectal cancer lesions at 3 years after polypectomy to improve stratification and surveillance programs.

Methods: We included patients with high-risk lesions (HRLs), defined as advanced adenoma (AA), large serrated polyps (SPs), and multiplicity (≥3 of any adenomas/SPs).

[Olfactory dysfunction in COVID-19, a review of the evidence and implications for pandemic management].

There is debate as to whether olfactory dysfunction should be considered a symptom of COVID-19 infection. We undertook a systematic literature review of the articles indexed in PubMed on olfactory disorders in viral respiratory tract conditions, with special emphasis on COVID-19. The main objective was to find evidence of clinical interest to support the relationship between anosmia and COVID-19.

[Olfactory dysfunction in COVID-19, a review of the evidence and implications for pandemic management].

There is debate as to whether olfactory dysfunction should be considered a symptom of COVID-19 infection, given the implications for managing the symptom itself, for diagnostic testing, and for implementing isolation measures. We undertook a systematic literature review of the articles indexed in PubMed on olfactory disorders in viral respiratory tract conditions, with special emphasis on COVID-19. The main objective was to find evidence of clinical interest to support the relationship between anosmia and COVID-19.

Incidental focal uptake in colorectal location on oncologic ¹⁸FDG PET and PET/CT studies: histopathological findings and clinical significances.

Purpose: Unexpected focal colonic or rectal radiotracer activity is an usual finding in patients subjected to a PET study. The aim of this work has been to evaluate the clinical significance of this finding in the prediction of an existing colorectal malignancy.

Material And Methods: During the last three years, all patients studied with (18)F-FDG PET/CT and PET for oncologic work-up purposes were prospectively surveyed for focal colorectal radiotracer activity.
