Authors describe two cases of intoxications imitating of morphological changes in the brain in this work. Initially it was meant to stem a stroke. Later, it was found that it is an intoxication by Amanita dapple. To this must be meant in practice and at the first contact with the patient.

This case report describes a case of fatal intestinal obstruction in a 4-year-old girl caused by malrotation and internal hernia, which led to distortion and necrosis of the small intestine. Although resuscitation was immediately initiated, multiorgan failure and death occurred within hours of the onset of the first symptoms. Autopsy revealed extensive ischemic changes in the small intestine and a congenital mesocolon defect as the cause of the internal hernia. This case highlights the critical importance of considering internal hernias in the differential diagnosis of acute abdomen in pediatric patients and emphasizes the need for prompt surgical intervention. Early recognition and treatment are essential to prevent catastrophic consequences in these rare but life-threatening conditions.

Whole-body post mortem CT angiography (PMCTA) is an innovative and experimental imaging technique that relies heavily on interdisciplinary collaboration, access to skilled personnel, advanced technical equipment and the financial possibilities of the workplace. Native CT examinations (PMCT) prior to autopsy are already a standard procedure in certain forensic departments in the Czech Republic (e.g., murders, suicides, deaths of children, traffic accidents etc.). Nonetheless, the progression of forensic sciences all over the world shows the necessity to integrate other advanced imaging modalities in routine forensic practice. Incorporating PMCTA into standard forensic workflows enhances the precision of forensic diagnostics, supplements traditional autopsy findings, and elevates the objectivity of forensic outputs. This paper presents technical notes on the development of PMCTA in forensic practice in a department that since 2015 until now has routinely performed native CT examinations. Institutional support was crucial in enabling the adoption of the imaging technique, which has so far been applied to more than thirty cases. The department is currently conducting a comparative study focused on the application of three different types of perfusion media - polyethylene glycol (PEG), saline, paraffin oil - and assessing the diagnostic efficacy of PMCTA relative to conventional autopsy. Based on our experience, PMCTA is suitable for all corpses except those with advanced post-mortem decomposition or extensive open injuries. The highest diagnostic yield is achieved in cases involving suspected gastrointestinal bleeding or vascular pathologies and lesions especially of large vessels (e.g., dissection/rupture of the aorta). The protocol for whole-body PMCTA can be adapted to meet the specific needs and conditions of individual forensic departments, providing a flexible yet robust framework for enhancing forensic medical investigations.

Previous studies have reported that respiratory infections can cause sudden death in infants. In one report, many infants had mild respiratory infection symptoms before their sudden death. However, we have also seen many cases of sudden death in asymptomatic infants who were diagnosed with respiratory infections based on detailed postmortem examinations. However, no study has investigated the differences between symptomatic death and asymptomatic death in infants with respiratory infections. In the present study, the risk factors for sudden death in infants with asymptomatic antemortem respiratory infections were investigated using forensic autopsy cases in our laboratory. The investigation showed that deaths associated with asymptomatic respiratory infections were relatively more common in infants younger than one year, of normal birth weight, and fed exclusively with formula milk, as well as infants who had fallen asleep within one hour of their last meal. The results reconfirmed that such small daily changes, such as expression and behavior changes, should be carefully observed when managing infants, including those with no apparent health problems.

This review article highlights the crucial role of organ weights and dimensions as key indicators in forensic diagnosis. Organ weight changes serve as valuable markers for pathological conditions, aiding forensic doctors in interpreting autopsy findings. The review emphasizes the importance of precision in establish- ing organ reference values, considering factors like population-specific norms and correlations with body parameters. Furthermore, it explores the impact of obesity on organ weights, emphasizing the need for updated databases that accurately reflect diverse populations. The article underscores the inadequacy of relying on outdated sources and advocates for creating a comprehensive and updated database of organ weights and dimensions for the local population, essential for accurate forensic interpretations.

Avalanche fatalities are quite rare in the Czech Republic. Due to the presence of avalanche fields in the two Czech mountains, forensic pathologists at some forensic medicine departments may encounter this specific mechanism of accidental death. The authors summarize medicolegal aspects of deaths in avalanches in the territory of the Czech Republic for the twenty-three-year period between 1993-2015. Ten avalanche fatalities were recorded during study period. The studied group consisted of nine male and one female victims. The average age of the deceased was 27.9 years. Skiers or ski-alpinists died in the avalanche in five cases (50%), climbers in two cases (20%), snowboarders in one case (10%), cross-country skiers in one case (10%) and in one case it was a fatality of child playing on a snowy hill (10%). The cause of death was suffocation in four cases (40%), blunt trauma in four cases (40%), and in the remaining two cases it was the survival of trapped persons several hours after being rescued from the avalanche in the hospital; both victims subsequently died as a result of prolonged shock (20%) due to a combination of prolonged suffocation and hypothermia. The time interval from the fall of the avalanche to the rescue of the trapped person was in the range of minutes to 3 hours. The presence of alcohol or drugs was not detected in any studied case.

Death from positional asphyxia occurs when the victim is found in a position that interferes with adequate breathing. We present an unusual case of a 67-yearold man who was found deceased trapped in a badger sett. The autopsy revealed marked congestion, cyanosis and a multitude of pinpoint hemorrhages in the face, neck and upper chest. Confluent scleral and conjunctival hemorrhage were observed and numerous petechial bleedings were found in the oral mucosa and within the reflected scalp. Death was attributed to positional asphyxia due to head-down position in a badger sett.

This article describes a method of introducing postmortem CT angiography into daily forensic medicine practice involving cases of limb stab wounds investigated at the Department of Forensic Medicine, University Hospital Ostrava. The essential preparation of the vessels as well as practical tips facilitating the subsequent performance of a classic autopsy are described in detail. Article also includes brief review of published papers dealing with PMCT angiography related issues, advantages which brings CT angiography into forensic routine work, but also its limits and pitfalls.

The authors present the case of a fatal accident of a 16-year-old skier who crashed into a tree during a downhill skiing lesson at school. Although the skier was wearing a protective helmet at the time of the accident and his condition did not appear to be too serious immediately after the accident, he later died in hospital as a result of a craniocerebral injury with cerebral contusion and intracranial haemorrhage. His life could not be saved even by immediate neurosurgery, during which fragments of the broken protective helmet were removed from his cranial cavity. By analysing the international literature, the authors identify head and brain injuries as the most common immediate cause of death in downhill skiing and provide insights into the possibilities of preventing these injuries by simple technical means on the part of ski area operators. These means are in particular protective covers for lift columns and protective nets placed in front of fixed, non-movable obstacles on the track.

Presented case study deals with the sudden death of a 47 years old male, shortly after a mountain bike race after reported nausea and chest pain followed by loss of consciousness and resuscitation. Cardiopulmonary resuscitation was unsuccessful. An autopsy was enacted due to the sudden death in a seemingly healthy person. An acute infarction of the anterior cardiac wall on the basis of stenosis of the anterior interventricular branch of the left coronary artery with histopathological findings of eosinophilic coronary periarteritis was assessed. Sudden death during sport activities represents a complex problem which forensic physicians have to face. An external and internal examination of the body is not always sufficient. It is crucial for the forensic physician to have sufficient knowledge and enough information about the circumstances of the death and anamnestic records. Eosinophilic coronary periarteritis occurs rarely, predominantly in males and with uncertain etiology.
