Objective: In sub-Saharan Africa, only a few studies of neurologic complications of human immunodeficiency virus 1 (HIV-1) infection have been done. The authors studied neuropathology of HIV-1 infection in Tanzania.
Design: Forensic autopsy study at Dar es Salaam, Tanzania.
Setting: A joint research project between Dar es Salaam, Tanzania, and Kumamoto, Japan.
Patients: Thirty patients with risk factors for HIV-1 infection.
Main Outcome Measures: Human immunodeficiency virus 1 infection was evaluated by HIV-1 antibody test on postmortem serum samples. The brains of HIV-1-infected persons were studied histopathologically.
Results: Infection with HIV-1 was identified on postmortem serum samples in 10 of 30 forensic autopsy cases. Neuropathologic changes of the brain were observed in 8 of the 10 HIV-1-infected persons; these changes consisted of lymphocytic meningitis, bacterial meningoencephalitis, cryptococcal meningoencephalitis, tuberculous meningitis with brain abscesses, and intracerebral hemorrhage.
Conclusions: Because none of the persons studied was suspected to have had brain diseases before autopsy, the results suggest that brain diseases of HIV-1-infected patients are likely to go unrecognized in Tanzania. In addition, the high incidence of neuropathologic findings in HIV-1-infected persons indicates that HIV-1-related brain diseases are common in Tanzania, as they are in developed countries. Further forensic autopsy study will determine the range and prevalence of brain complications and have immediate impact on the management of HIV-1-infected patients in Tanzania and other developing countries.

Following the establishment of Nepal's first medical college in 1972, forensic medicine was introduced in 1978. To date, 25 medical colleges in the country have included forensic medicine as a compulsory subject in the undergraduate medical curriculum. Although this subject has been introduced into the medical curriculum, the outcome is unsatisfactory, as reflected by the poor medico-legal reports prepared by newly graduated medical students.

Background: Femicides, defined as the gender-based killing of women, are a pressing public health issue worldwide, with South Africa experiencing some of the highest rates globally. This study focuses on the North-west region of Tshwane, particularly the Garankuwa area, aiming to address gaps in understanding the epidemiology, demographics, circumstances, and pathology associated with femicides. The Garankuwa mortuary serves as the primary site for this investigation, providing a detailed analysis over a ten-year period, shedding light on contributing risk factors in the context of systemic gender inequality.

Department of Nephrology, Japan Community Healthcare Organization Sendai Hospital, 981-3281, Sendai, Miyagi, Japan.
Background: Oliguric acute kidney injury (AKI) is one of the critical conditions which needs emergent treatment due to the lack of the capacity of excreting toxins and fluids, and plasma membrane bleb formation is considered as one of the characteristic morphologic alterations in ischemic AKI in both animal models and human. We present here an autopsy case with clear electron microscopy images capturing a definitive instance of blebbing in ischemic AKI.
Case Presentation: A 66-year-old man was admitted for oliguric AKI with nephrotic syndrome (NS).

Background: Data on the occurrence of unexpected sudden cardiac death (SCD) in different seasons are limited.
Methods: All unexpected sudden death victims have to undergo medico-legal autopsy obligated by the Finnish law. Consecutive series of all unexpected autopsied SCD victims (n=5,869) were prospectively collected from the geographically defined area in the Northern Finland during a twenty years period from 1998 to 2017.
