Abstract The article presents two cases of the Arad Medico-Legal Department illustrating just a part of the role of the forensic pathologist at the death scene but there are sufficient to fully justify the importance of this investigation as no example can comprise the complexity of problems and the particularity of each case, nor a statistic can be made. Both cases were found dead at home and forensically autopsied, but the two of them were distinct in terms of forensic pathologist's request death scene participation. In the first case, the autopsy did not find traumatic lesions, but revealed that the death was due to massive hemoptysis caused by cavernous tuberculosis with subsequent exsanguination, microscopically confirmed. The death was nonviolent. In the second case, the autopsy revealed findings of mechanical asphyxia due to neck compression, both macroscopically and microscopically. The death was violent. In both cases the forensic expert participation is required at the death-scene. In the first case it allowed the correct interpretation of the traces of blood found on site, and in the second case, an onsite research would have properly helped for restoring the death‟s occurrence. The scene investigation and autopsy provide, together, the basis for an accurate determination of cause and circumstances of death.

Background and Purpose: An accurate determination of the cardioembolic risk in patients with atrial fibrillation (AF) is crucial to prevent consequences like stroke. Obstructive sleep apnea (OSA) is a known risk factor for both AF and stroke. We aim to explore a possible association between OSA and an increased cardioembolic risk in patients with AF. Methods: We assessed data from the ESADA (European Sleep Apnea Database) cohort where patients with known AF and OSA were included. Parameters of OSA severity and related hypoxia like lowest Sp o 2 and 4% oxygen desaturation index were analyzed. Patients were stratified according to their cardioembolic risk estimated with the CHA 2 DS 2 -VASc score. Results: From the initial cohort of 14 646 patients, a final set of 363 patients were included in the analysis. Indices of hypoxia during sleep were associated with increased CHA 2 DS 2 -VASc score (4% oxygen desaturation index 17.9 versus 29.6 versus 30.5 events/hour and the lowest Sp o 2 81.2 versus 77.8 versus 77.5% for low, moderate, and high cardioembolic risk, respectively, P <0.05). Conclusions: These results support the potential role of OSA-related hypoxia in the risk for cardioembolic complications such as stroke in patients with AF.
