In the daily practice of forensic pathology, sudden cardiac death (SCD) is a diagnostic challenge. Our aim was to determine the usefulness of blood biomarkers [creatine kinase CK-MB, myoglobin, troponins I and T (cTn-I and T), and lactate dehydrogenase] measured by immunoassay technique, in the postmortem diagnosis of SCD. Two groups were compared, 20 corpses with SCD and 8 controls. Statistical significance was determined by variance analysis procedures, with a post hoc Tukey multiple range test for comparison of means (p < 0.05). SCD cases showed significantly higher levels (p < 0.05) of cTn-T and cTn-I compared to the control group. Although only cases within the first 8 h of postmortem interval were included, and the control group consisted mainly of violent death cases, our results suggest that blood troponin levels may be useful to support a diagnosis of SCD.

Introduction: Sudden death (SD) is a health problem worldwide affecting all strata of the population. The main cause of SD is ischemic heart disease (IHD). The aims of the study were as follows: (i) to analyze the incidence of deaths from IHD in two successive periods (1998-2006 and 2007-2015) to visualize the magnitude of the problem and (ii) to review the official reports of SD in the same lapse of time. Materials and Methods: During that period, instantaneous death (ISD) and death that occurred in the first 24 h after the onset of symptoms were analyzed according to the official databases of National

Breast density (BD) is a risk factor for breast cancer. Aims. To describe BD patterns in asymptomatic Mexican women and the pathological mammographic findings. Methods and Material. Prospective, descriptive, and comparative study. Women answered a questionnaire and their mammograms were analyzed according to BI-RADS. Univariate (χ 2) and conditional logistic regression analyses were performed. Results. In 300 women studied the BD patterns were fat 56.7% (170), fibroglandular 29% (87), heterogeneously dense 5.7% (17), and dense pattern 8.6% (26). Prevalence of fat pattern was significantly different in women under 50 years (37.6%, 44/117) and older than 50 (68.8%, 126/183). Patterns of high breast density (BD) (dense + heterogeneously dense) were observed in 25.6% (30/117) of women ≤50 years and 7.1% (13/183) of women >50. Asymmetry in BD was observed in 22% (66/300). Compression cone ruled out underlying disease in 56 cases. In the remaining 10, biopsy revealed one fibroadenoma, one complex cyst, and 6 invasive and 2 intraductal carcinomas. 2.6% (8/300) of patients had non-palpable carcinomas. Benign lesions were observed in 63.3% (190/300) of cases, vascular calcification in 150 cases (78.9%), and fat necrosis in 38 cases (20%). Conclusions. Mexican women have a low percentage of high-density patterns.

Background: Up to the present, NAFLD diagnosis has been established through the invasive method of biopsy. The search for a non-invasive alternative, for example biomarkers, is a motive for research. Previous studies have shown that for diabetic or obese patients with NAFLD, the profile of liver enzymes as NAFLD biomarkers has so far not defined pathological liver condition as such. This study aim was comparatively analyze the results of previous research on liver function enzymes of obese patients with NAFLD and to corroborate them with this type of patient in Veracruz.
