A systemic review and recommendation for an autopsy approach to death followed the COVID 19 vaccination.

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started in December 2019. An immediate prevention approach for the outbreak is the development of a vaccination program. Despite a growing number of publications showing the effectiveness of vaccination in preventing SARS-CoV-2 outbreak and reducing the mortality rate, substantial fatal adverse effects were reported after vaccination. Confirmation of the causal relationship of death is required to reimburse under the national vaccination program and could provide a reference for the selection of vaccination. However, a lack of guidelines in the laboratory study and autopsy approach hampered the investigation of post-vaccination death. In this paper, we performed a systematic electronic search on scientific articles related to severe Covid-19 vaccination adverse effects and approaches in identifying the severe side effects using PubMed and Cochrane libraries. A summary on the onset, biochemistry changes and histopathological analyzes of major lethally side effects post-vaccination were discussed. Ultimately, a checklist is suggested to improve the quality of investigation.

Intestinal Obstruction Secondary to Malformation in a Child with Mayer-Rokitansky-Küster-Hauser Syndrome.

BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by underdevelopment of the uterus and vagina. CASE: A 4-year-old girl was declared dead on arrival to the hospital with a history of chronic constipation since birth. Postmortem examination showed Müllerian remnants attached to abnormal fibrous tissue. The fibrous tissue extended from the descending colon to the rectum and connected to a urinary bladder duplication cyst. The fibrous tissue formed into a constricted band around the rectum. The cause of death was Streptococcus pyogenes sepsis with intestinal obstruction secondary to the rectal fibrotic band and urinary bladder duplication cyst. SUMMARY AND CONCLUSION: MRKH syndrome is a rare congenital disorder, and the malformations rarely cause death. We describe the features of abnormal fibrous tissue and urinary bladder duplication cyst in a patient with MRKH syndrome.

Cardiac beriberi: morphological findings in two fatal cases.

Cardiovascular beriberi is categorized into two main groups, according to its cause: alcoholic and non-alcoholic (dietary). Cardiovascular beriberi can also be divided into a fulminant form (Shoshin beriberi) and a chronic form. Shoshin beriberi is characterized by hypotension, tachycardia, and lactic acidosis and is mainly encountered in non-alcoholic patients in Asian countries, although it has also been seen in alcoholics in Western countries. Due to the complex clinical presentation and to the lack of diagnostic tests, thiamine deficiency is still being missed, especially among non-alcoholics patients. We present two fatal cases of non - alcohol associated cardiac beriberi. An acute myocardial infarction was observed in one case; extensive colliquative myocytolisis (grade 2) was described in the second case respectively. Morphologically, myocardial necrosis and colliquative myocytolysis are the histologic hallmarks of this acute, rare clinical entity. An increase in apoptotic myocytes was demonstrated probably sustaining the cardiogenic shock.
