    Title translation Analysis of the major clinical-pathological discrepancies in autopsies of adults in a tertiary referral hospital between 2008-2017.
    Abstract Objective: To compare and contrast clinical diagnoses with autopsy findings in order to identify unexpected, relevant discrepancies.
    Material and method: A retrospective observational study of the revision of autopsies of adults and their respective medical records in order to classify them according to referral department and Goldman's classification was carried out at the Central University Hospital of Asturias between 2008-2017.
    Results: 694 (52.6%) of 1320 autopsies were included in the study. Discrepancies were observed in 57.6% of cases, although the majority (39.3%) were minor. Type I discrepancies were identified in 63 autopsies (9.1%); malignant neoplasms being the main pathology observed (57.1%), mainly of gastrointestinal origin (about 28%). The second most common discrepancy was found in cases of infectious diseases (23.8%) followed by pulmonary embolism (15.9%). 64 autopsies were classified as type II discrepancies (9.2%), with myocardial infarct the most common (37.5%), especially acute myocardial infarction (18 cases), followed by bronchoaspirations (18.7%), DIC (15.6%), massive haemorrhages (9.4%) and other conditions. It was considered that both the ICU and the Internal Medicine Service were responsible for the largest number of major discrepancies (type I and II), accounting for about 45% of type I and slightly more than 56% for type II.
    Conclusion: Autopsies are an essential means of identifying ante-mortem clinical errors. The incidence of major discrepancies in the Central University Hospital of Asturias (18.3%) is comparable to that of leading hospitals worldwide.

    Abstract Barrett's esophagus (BE) is the most important risk factor for the development of esophageal adenocarcinoma. It develops through a progressive sequence of histologic and molecular events that begin with metaplasia and then progresses through various stages of dysplasia. Matrix metalloproteinases are involved in the degradation of the extracellular matrix and play an important role in tumor progression. The immunohistochemical expression of MMP-1, TIMP-2 and p53 in 111 samples from 45 patients diagnosed with BE with and without dysplasia and adenocarcinoma of the esophagus was retrospectively studied, and statistical analysis was conducted to measure the association between their expression and the degree of dysplasia present. MMP-1 was expressed in 33.3% of the samples studied, mainly in the adenocarcinoma subgroup with up to 40% positive cases (p = 0.494). In contrast, TIMP-2 was expressed in 25.2% of the samples, and no positive cases were identified in the adenocarcinoma subgroup (p = 0.037). Aberrant p53 expression was observed in 81.4% of the samples diagnosed with some degree of dysplasia (p < 0.001). MMP-1 showed no statistically significant differences between diagnostic entities. A statistically significant loss of TIMP-2 expression was observed in distal esophageal adenocarcinoma samples, which contrasts with the aberrant expression of p53 in dysplastic cases.

    Abstract Introduction: Smartphone applications (apps) have become increasingly prevalent in medicine. Due to most pathologists, pathology trainees, technicians, and medical students use smartphones; apps can be a different way for general pathology education. "General pathologist-helper (GP-HELPER)" is a novel app developed as a reference tool in general pathology and especially for general pathologists, developed for Android and iOS platforms.
    Materials and methods: "GP-HELPER," was created using Mobincube website platform. This tool also integrates "FORUM GP-HELPER," an external website created using Miarroba website (http://forum-gp-helper.mboards.com) and "COMMUNITY GP-HELPER" a multichannel chat created using Chatango website platform.
    Results: The application was released in July 2015, and it is been periodically updated since then. The app has permanent information (offline data) about different pathology protocols (TNM latest edition, protocols regarding management of tumors of unknown primary origin, and flowcharts for some of the most difficult tumors to diagnose) and a database with more than 5000 immunohistochemistry results from different tumors. Online data have links to more than 1100 reference pathology video lectures, 250 antibodies information, more than 70 pathology association websites, 46 pathology providers, and 78 outstanding pathology journal websites. Besides this information, the app has two interactive places such as "FORUM GP-HELPER" and "COMMUNITY GP-HELPER" that let users to stay in touch everywhere and every time. Expert consult section is also available.
    Conclusions: "GP-HELPER" pretends to integrate offline and online data about pathology with two interactive external places in order to represent a reference tool for general pathologists and associate members.

    Title translation Study of the evolution in the activity of a Department of Pathology from a third level hospital in the last decade (2007-2016).
    Abstract Objective: To study the evolution of variables of interest in a department of pathology from a third level hospital during the last decade and to evaluate the impact on these of the hospital relocation in 2014.
    Material and method: Retrospective observational study in which the recorded samples (biopsies, cytology specimens, FNA, autopsies, intraoperative) as well as the complementary techniques (IHC, Histochemistry, IF and FISH) and portfolio of services were analyzed during the years 2007-2016 inclusive. For the statistical analysis, the five-year periods 2007-2011 and 2012-2016 were compared.
    Results: The following variables were statistically significant: cytology (34055.8±1994.0 vs 26590.4±2938.3, p=0.002), autopsies (156.2±27.3 vs 122.0±14.78, p=0.039), immunohistochemistry (17855.4±3424.2 vs 28559.2±4734.7, p=0.003), histochemistry (11117.8±2300.9 vs 6225.0±1330.5, p=0.003) and immunofluorescence (610.2±185.3 vs. 1205.4±154.0, p=0.001). Statistical correlations of interest among variables have been identified. In 2014, it was observed that the variables of greater specific weight (biopsies, cytology, IHQ and histochemistry) in the work load of the Department showed an average decrease of 12.5%. A generalized increase in the panel of available samples has been identified, the largest increase being seen in the number of antibodies (78.7%), histochemistry (38.7%) and FISH (400%).
    Conclusion: Relevant variations in work volume, as well as the service portfolio, have been identified, especially in the techniques aimed at improving diagnostic accuracy (IHQ and FI), and a significant decrease in the number of cytology specimens, autopsies and histochemistry. In the year 2014 a decrease of more than 12% in the main variables of the study was observed.

    Abstract Cutaneous squamous cell carcinoma (cSCC) is the second most common form of skin cancer. The incidence of metastasis for cSCC is estimated to be around 1.2-5%. Ribosomal protein S6 (p-S6) and the p21 protein (p21) are two proteins that play central roles in other cancers. These proteins may be equally important in cSCC, and together, these could constitute a good candidate for metastasis risk assessment of these patients. We investigate the relationship of p-S6 and p21 expression with the impact on the prognosis of head and neck cSCC (cSCCHN). p-S6 and p21 expression was analyzed by immunohistochemistry on paraffin-embedded tissue samples from 116 patients with cSCCHN and associations sought with clinical characteristics. Kaplan-Meier estimators and Cox proportional hazard regression models were also used. The expression of p-S6 was significantly inversely associated with tumor thickness, tumor size, desmoplastic growth, pathological stage, perineural invasion and tumor buds. p21 expression was significantly inversely correlated with >6 mm tumor thickness, desmoplastic growth, and perineural invasion. p-S6-negative expression significantly predicted an increased risk of nodal metastasis (HR = 2.63, 95% CI 1.51-4.54;

    Abstract PTEN-induced kinase-1 (PINK1) is the initiator of the canonical mitophagy pathway. Our aim was to study the immunoexpression of PINK1 in surgical specimens from ninety patients with metastatic colorectal adenocarcinoma (CRC) to the liver (CRLM). Tissue arrays were produced, and immunohistochemical studies were analyzed by the H-Score method. The mean immunoexpression of PINK1 in normal tissues was between 40 to 100 points. In tumoral tissues, positive PINK1 immunoexpression was observed in all samples, and no differences were noted between CRCs. In CRLMs, a significant under-expression was noted for PINK1 from the rectum (71.3 ± 30.8;

    Abstract A previously healthy 12-year-old boy had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related multisystem inflammatory syndrome (MIS-C) that was rapidly fatal. Autopsy revealed the presence of a large intracardiac thrombus. SARS-CoV-2 spike protein was detected in intestinal cells, supporting the hypothesis that viral presence in the gut may be related to the immunologic response of MIS-C.
