Objective:In our study, we aimed to determine the accompanying cardiac pathologies and accompanying findings in other organs in the cases of giant cell myocarditis.Methods:The histopathology reports of the autopsied cases between 2011 and 2020 were reviewed. Cases diagnosed with myocarditis were evaluated retrospectively according to their histopathological pattern. According to the histopathological pattern, it was divided into subgroups as neutrophilic, lymphocytic, lymphohistiocytic, eosinophilic, myocarditis accompanied by granulomas, and giant cell myocarditis. Age and gender distribution, death patterns, autopsy findings, concomitant cardiac pathologies, and histopathological findings in other organs of the cases diagnosed with giant cell myocarditis were evaluated retrospectively.Results:Between 2011 and 2020, 558 of 49,612 autopsies performed in Morgue Department of the Council of Forensic Medicine were diagnosed as myocarditis in the histopathological examination. 1.02% (n=6) were giant cell myocarditis. Three of the cases with giant cell myocarditis were male and three were female. Histopathological findings were similar in all cases diagnosed with giant cell myocarditis. The mean age was found to be 55.66 (31-80). Heart weight ranged from 433-740 gram. Mononuclear cells, polymorphonuclear leukocytes and, eosinophils accompanying giant cells were seen in the inflammatory infiltrate with necrosis. On macroscopic examination, variegated discoloration and scarring on the ventricular wall was the most common finding. Giant cell myocarditis resulted was the cause of death in four cases. Lobular pneumonia was observed in the lungs in two cases. One case had acalculous cholecystitis.Conclusion:Autopsy and histopathological diagnosis in sudden and unexpected deaths gain importance to diagnose giant cell myocarditis.

Objective:It is aimed to reveal the demographic characteristics of patients who died due to non-traumatic aortic dissection, the findings that will increase the risk of aneurysm and dissection, and the complications that develop after dissection, in the light of histopathological findings.Methods:One hundred thirty-eight cases diagnosed with non-traumatic aortic dissection, whose autopsies were performed in Council of Forensic Medicine Morgue Department between 2014 and 2018, were retrospectively analyzed. Age and gender distribution, body mass index, distribution of dissection types, complications that may develop after dissection in organs, and histopathological changes in the aortic wall were evaluated.Results:Cardiac tamponade was detected in 67.4% (n=93) of the cases, tamponade and hemothorax in 15.9% (n=22) and hemothorax in 11.6% (n=16). 5.1% (n=7) had a bicuspid aortic valve. 28.2% (n=39) had atherosclerosis, 21.7% (n=30) had elastic degeneration, and 10.8% (n=15) had cystic medial necrosis. In 55.8% (n=77), pathological changes in the vessel wall were not reported. There was widespread intraalveolar bleeding in 34.8% (n=48) and focal intraalveolar hemorrhage in 6.5% (n=9). When cardiac findings were examined, myocardial infarction was observed in 2.2% (n=3).Conclusion:In cases of aortic dissection, a detailed macroscopic and microscopic examination should be performed together with the clinical history. Histopathological examination of the dissected area is important in demonstrating the underlying factors. Histopathological findings in the organs may be useful in predicting the complications of the disease. Autopsy has a critical importance not only in recognizing and understanding the disease, but also in determining the treatment methods to be applied for the disease.

Amaç: Resveratrol, ilk olarak 1940 yılında Melanthiaceae (Dokuztepegiller) familyasında yer alan bitkinin köklerinden izole edilmiştir. Bitkilerde özellikle kırmızı üzüm, yer fıstığı, ananas, dut ve yaban mersininde yüksek konsantrasyonda bulunmaktadır. Resveratrol (3,5,4'-trihidroksistilben) antioksidan, antifungal, antibakteriyel, anti-inflamatuar, anti-proliferatif etkilerin yanında çeşitli biyokimyasal etkilere sahip doğal bir polifenoldür. Bitkiler tarafından mikrobik, fungal ve fiziksel uyaranlara karşı üretilen antimikrobiyel ve antifungal etkili bir bileşik yani fitoaleksindir. Bu çalışmada Polygonum Cuspidatum kökünden elde edilen resveratrolün bazı mikrobik ve fungal insan enfeksiyonları üzerindeki çoğalmayı azaltıcı veya durdurucu etkisi olup olmadığı araştırılmıştır. Yöntem: Bu çalışmada Candida albicans, Escherichia coli, Pseudomonas aeruginosa ve Staphylococcus aureus mikroorganizmaları kullanılmıştır. Çalışmada kullanılan mikroorganizmaların her biri üremeleri için uygun besiyerlerine ekilmiştir. Her bir mikroorganizma biri normal şartlarda (resveratrol içermeyen) diğerleri ise 1/4 ve 1/1 dilüsyon oranlarında resveratrol içeren besiyerlerine ekilmiş ve organizmaların üremeleri için belirli sürelerde inkübasyona bırakılmıştır. Bulgular: Bu süre sonunda resveratrol içermeyen besiyerinde Staphylococcus aureus'un beta hemoliz ve üremesi saptanırken, 1/1 ve 1/4 dilüsyonlu resveratrol içeren %5 koyun kanlı besiyerinde beta hemoliz yapma yeteneği kaybolmuş olup 1/1 ve 1/4 dilüsyonlu resveratrol içeren Mueller Hinton besiyerinde üremesi inhibe olmuştur. Resveratrol içermeyen ve içeren (1/1 ve 1/4 dilüsyonlu) besiyerlerinde Escherichia coli, Pseudomonas aeruginosa ve Candida albicans mikroorganizmalarının üremelerinde değişiklik saptanmamıştır. Sonuç: Resveratrolün gram pozitif bakteriler üzerindeki etkilerinin yanında çeşitli antibiyotikler ve dezenfektanlar ile kombine edilerek tedavi edici ve koruyucu etkinliği yeni yapılacak çalışmalarla değerlendirilebilir.

Sarcina ventriculi is a gram-positive anaerobic coccus with characteristic tetrad morphology. Sarcina ventriculiis identified by light microscopy with features of basophilic staining, cuboidal shape, tetrad morphology, and refractile nature. There have been very few case reports of Sarcina ventriculi reported in the literature. We present a case of a 53-year-old male, with gastric ulcer perforation where peritonitis was incidentally found to harbor Sarcina ventriculi in postmortem histopathological examination. Most of the cases exhibit abdominal pain, nausea, vomiting and delayed gastric emptying. It has also fatal life-threatening complications, such as gastric perforation and emphysematous gastritis. The histopathological examination has a key role for identification of the bacteria. The pathologist must always keep it in mind these bacteria as a cause of gastric ulcer perforation in the differential diagnosis. We want to present a case of a 53-year-old male gastric ulcer perforation who was found dead in his bed.

Pneumocystis jiroveci is the most common and serious opportunistic infection in acquired immune deficiency syndrome patients. It is detected in approximately 80% of human immunodeficiency virus (HIV) infected individuals. In this paper, we present a case of pneumocystic jiroveci pneumonia in a 32-year-old HIV-infected patient who committed suicide. We also present histopathological findings in the lung and aim to draw attention to suicidal tendency in HIV-infected individuals.

Cryptococcus neoformans is a highly mortal opportunistic yeast causing pneumonia and meningoencephalitis in cases with HIV infection. In rare cases, it causes systemic infections, spreading to organs like the spleen, liver, and kidneys. In this paper we present the post-mortem evaluation results of a systemic cryptococcal infection in a HIV-positive case found dead at home. A 30-year-old, 167 cm tall, 57 kg Chinese man found dead at home was sent to the Morgue Department for autopsy. In the anogenital region, multiple papular lesions,which were found 1 cm in diameter, off-white, having hard consistency, and raising from surface, were found. In autopsy, edema was found in the brain and cerebellum and cerebellar tonsils were prominent. The brain weighed 1561 g. Right lung was found 943 g and left lung 800 g in weight. Yeast growth was observed in the aerobic cultures of CSF, lung and spleent issue. The yeast form was defined as C. neoformans with API 32 C and Maldi-T of method. In addition, Serratia marcescens grew in blood and lung tissue culture. Plenty of gram-negative bacilli were seen in the Gram stain of tissue smear. In the post mortem histopathological examination of the tissues, histiocytic-pneumonia caused by cryptococcus and bacterial bronchopneumonia findings were seen in lungs and the parenchyma of the brain, and other organs were reported to be widely in vaded with cryptococcus. HIV-RNA was found positive in high quantitation in the blood sample of the case. HIVpositive immunocompromised people often die due to opportunistic infections. Our case died due to pneumonia infection caused by C. neoformans and secondary infection with S. marcescens and meningo encephalitis caused by systemic cryptococcus infection. Therefore, AIDS and related opportunistic infections should be strongly considered in cases where there is death of a foreign person at home with unknown clinical data and stories.

Phenylthiocarbamide (PTC) is known as phenylthiourea and it is an organic compound that has the phenyl ring. Ability to perceive the tastes of PTC chemical is related to the dominance of taste genes. There are a large number of population studies regarding the PTC taste perception and different personal characteristics or disease conditions. The purpose of this study is to reveal and compare the relation between the PTC taste perception and work-out habits, smoking, alcohol consumption and tendency to the depression of people. A total of 2500 adults were volunteered to be included in this study. PTC taste perception was measured by tasting with PTC solution (10 mg/L) filtered in a paper. It showed that tasters were significantly more frequent (81.8%) than nontasters (18.2%) in all population. And in some parameters analyzed in this study, there are significant differences. The taste genetics show up with environmental factors and create the sense of taste, which develops the feeding behaviors. The taste perception resulting from food and beverages diversifies by genetic and environmental effects and the nervous system interprets this perception. This study is enlightening in terms of presenting that the taste perception of people affects their lifestyles and lead them to start and either continue or discontinue some habits.
