Background: Fat embolism (FE) may develop following many traumatic and atraumatic clinical conditions; however, fewer data exist regarding the occurrence of isolated pulmonary FE (IPFE). Cardiopulmonary resuscitation (CPR) is an emergency procedure for maintaining blood circulation and oxygenation during cardiac arrest. In this study, we aimed to evaluate the association of CPR with IPFE in autopsy cases. Methods: A total 402 cases among 4,118 autopsies were diagnosed with IPFE, and the medical background of these cases was retrospectively evaluated. Diagnosis of FE and FE grading were performed with histopathological examinations of postmortem tissue samples, and injury-severity scores of traumatic cases were assessed. Data of traumatic and atraumatic cases were statistically compared. Results: Of the IPFE cases, 298 (741%) were male and 104 (25.9%) female, with overall mean age 53.7 (2–99) years. Causes of death of studied subjects were traumatic for 302 (75.1%) and atraumatic reasons for 100 (24.9%) cases. CPR was performed for 277 cases of which 177 (63.9%) were traumatic and 100 (36.1%) were non-traumatic. In comparison to traumatic cases, significantly higher CPR frequency was determined in atraumatic IPFE ( P =0.001). High grade FE in the traumatic cases, and mild-moderate grade of FE in the nontraumatic cases were found statistically significant ( P =0.001). Conclusion: This study indicates that CPR may be one of the leading factors in the development of IPFE in atraumatic conditions, and this procedure was related to mild–moderate IPFE manifestations. Regardless of whether conditions were traumatic or atraumatic, in patients who survive following CPR for manifest ventilation/perfusion problems, it should be remembered that IPFE may have developed due to CPR.

Eosinophilic myocarditis in long term use of antipsychotics: case series and review of the literature Long term use of antipsychotics, is encountered in many psychiatric disorders, especially in schizophrenia. Eosinophilic myocarditis is a rare form of myocarditis characterized by myocardial inflamation composed of mostly eosinophils. It is known that it may develop at a rate of 0.2-3 % in long term therapies, especially with clozapine use. Standart treatment can not be established because of rarity of disease and difficulties in the determination of the etiology. In this article, three cases, who have been receiving long term drug treatment for schizoaffective disorder and faced sudden death, were presented. Their autopsies were performed in our institution. When myocardial sections were examinated with light microscope, common findings with three cases were, myocyte damage accompanied with patchy distribution of perivascular and interstitial inflamatory infiltrate rich in eosinophils. When the light microscopic findings evaluated with detailed medical history, autopsy findings and toxicological analysis results, we considered these entities may have developed as a result of hypersensitivity reaction due to long term antipsychotic drug use. Eosinophilic myocarditis is encountered as a rare clinical entity and probably it is a subtype of myocarditis that is overlooked. Failure in the clinical diagnosis and delay in treatment may lead to irreversible myocardial damage and death. Endomyocardial biopsy is still the gold standard in the diagnosis of eosinophilic myocarditis. Here, we present these cases since the drug use is the most frequently accused cause, it is rarely seen in acute deaths and the diagnosis can be reached by histopathological examination.
