Volatile substance addiction and toxic gas inhalation are now an important health problem. The pleasure-based inhalation of butane gas, also known as lighter refill gas, is especially prevalent among children and young people. The most important reasons for this situation are that they are cheap and easy to obtain and lack of legal supervision. The exhaled gas is absorbed through the alveolar surface and rapidly enters the bloodstream and leads to clinical signs. It can cause dizziness, nausea, vomiting, confusion, hallucinations, and euphoria in the acute phase. In severe cases, bronchospasm, hypoxia, ventricular arrhythmia, cardiopulmonary arrest, and death can occur. Our case is one of the rare cases in the literature that was diagnosed by postmortem histopathological examination. Our case is a 15-year-old girl who was found in front of a tobacco product store. On gross examination, there was a hemorrhagic area under the aortic valve that continued to interventricular septum. There was no coronary artery lesion. Histopathological examination revealed hypereosinophilia and contraction band necrosis in myocardial fibers, which was more intense in papillary muscle. Immunohistochemical studies also supported early myocardial ischemic changes. Upon toxicological examination, butane gas was detected in lung and blood samples.

Lower respiratory infections are commonly due to viruses and are the third largest cause of death. Respiratory tract viruses have a tendency to target the specific regions in the lung and can harm the host via direct effect of the virus and the host's inflammatory response. In this study, relationships between morphologic changes in the lung and the viral agent type isolated in the lung by the polymerase chain reaction technique were investigated. This study was performed retrospectively at 113 autopsy cases in the Council of Forensic Medicine in Istanbul. Slides from the lung tissues diagnosed as interstitial pneumonia and detected viral agent in polymerase chain reaction were evaluated and reviewed under light microscope by 2 pathologists simultaneously according to predetermined bronchiolar, alveolar, and interstitial findings. Alveolar findings were detected in 108 cases (95.6%), whereas interstitial and bronchiolar findings were detected in 91 (80.5%) and 38 (33.6%) cases, respectively. Intra-alveolar edema was the most common alveolar finding. Some findings such as multinucleated syncytial cells and smudge cells can aid the search for etiologic agent. Interstitial inflammation was the most common histopathologic finding in the lung in viral infections and the most prominent clue to viral infections in the lung histopathologically without discrimination of viral agent type.

The number of cases with spontaneous coronary artery dissection (SCAD) is considered to be being underestimated because of a large amount of SCAD leading to sudden death without previous diagnosis. Besides, not only in clinics but also in autopsy practice, correct diagnosis of SCAD is important to prevent forensic malpractice.The article is intended to discuss the pathological findings through the forensic point of view for improving the malpractice expertise in scope of clinicians' timely antemortem diagnosis according to risk factors and in scope of forensic pathologists' the cause of death determination ability according to macroscopical and microscopical findings of the autopsy.In 3 cases reported, the main characteristics were the female sex, pregnancy history and a sudden death without any trauma. However, although there are many women giving birth or using oral contraceptives, only some of them are facing with SCAD. This suggests the possibility of some hereditary factors, whereas hereditary characteristics may be understood in many different ways like hormone-releasing regulating mechanisms as well as immunity, morphology, or any other mechanism. For instance, autoimmunity has been also a hereditary underlying factor for vessel injury considered in presented cases.

WOS: 000382182000019 PubMed: 27389692 A lithopedion is a rare complication of pregnancy that occurs when a fetus in an intraabdominal location dies, and it is too large to be reabsorbed by the body. The case was an 87-year-old woman, and she was transferred to the morgue department in April 2014 to determine the cause of death. During autopsy, an intraabdominally located calcified dead fetus and a 12-cm diameter calcified cyst in the right ovary were incidentally detected. It was aged 25 to 29 weeks (according to femur and humerus measurements) with a size of 12.5 x 8 x 5 cm and a weight of 227 g. According to investigation reports, her husband died in 1990, and she had 3 deliveries, the most recent of which was in 1946. Because the menopause age of the case was not exactly known, the retention time of the lithopedion was supposed to be 24 to 68 years according to the date of the most recent pregnancy and the date of her spouse's death. It is the first case that has been incidentally detected and identified during an autopsy in Turkey and also one of the oldest cases in the literature.

Hydatid disease is a parasitic infestation caused by ingestion of eggs of echinococcal species. For Echinococcus granulosus, the definitive host is the dog, and sheeps are the usual intermediate hosts. Humans are accidental intermediate hosts, infected by ingestion of food contaminated with eggs shed by dogs or foxes. The most common organs that hydatid disease encountered are the liver and lungs. Involvement of the kidney is rare and usually accompanies the other organ involvements. Cardiac involvement of echinococcosis is also very rare. We report the case of a 31-year-old woman with a 6-year history of asthma who collapsed after strenuous activity and died despite the interventions carried out. At autopsy, cystic masses were detected in the apex of the heart, in the right kidney, and in the liver. There were no macroscopic pathologic findings in the other organs. Microscopic examination revealed the diagnosis of hydatid cyst in the heart, right kidney, and liver besides medial hypertrophy of the lung vessels. Cause of death was attributed to hydatid cyst and its complications. Patients who have symptoms akin to asthma at clinical presentation have to be further investigated for organic cardiac and pulmonary diseases such as hydatid cyst, especially in endemic countries.
