On 7 October 2023, a large-scale invasion by armed Hamas terrorists occurred in southern Israel. Approximately 1500 militants breached the Gaza security barrier using tractors, RPGs, and explosives. Concurrently, the terrorists utilized various means including armed vehicles, motorized paragliders, sea incursions, and a massive rocket attack launched toward Israel. On entering Israeli territory, the militants dispersed and targeted several towns, kibbutzim (collective communities), and Israel Defense Forces (IDF) military bases near Gaza. This strategy resulted in a death toll exceeded 1300 civilians and soldiers. In addition, more than 240 individuals were abducted. This attack occurred in one day. In this article, we introduce the Israeli National Institute of Forensic Medicine, which specialized in forensic analysis during mass casualty incidents, and pivotal role it played on 7 October. We present a detailed discussion on methods, challenges, and adaptations the institute took in response to the event of 7 October.

Background: Virtual autopsies by computer tomography (CT) or magnetic resonance imaging can be valuable in cases of unexplained infant death. The radiologist must be familiar with the normal appearance of all the segments of the thoracic aorta in normal and deceased children. A thorough review of the literature revealed no prior articles describing CT changes in the ascending aorta or the aortic arch in pediatric virtual autopsies.

Objectives: To compare the CT appearance of the thoracic aorta in deceased children and in those younger than 3 years of age.

Methods: Hospital registries were searched for cases of unexpected deaths in children younger than 3 years old, with a postmortem CT available, as well as for clinically indicated chest CT in children of the same age during a 5 year period. The ascending aorta (AA), aortic arch (arch), and the descending aorta (DA) diameters were measured. Student's t-tests and Mann–Whitney U-tests were used to compare the two groups.

Results: A total of 64 scans were reviewed: 35 postmortem and 29 performed on living patients. The differences in the diameter and the ratios of the diameter between the AA and the arch, as well as between the arch and the DA in the postmortem and living groups were statistically significant (P < 0.05).

Conclusions: On postmortem CT scans, we found focal tapering of the aortic caliber at the level of the arch between the origin of the brachiocephalic artery and left subclavian artery. This finding should not be misinterpreted as a hypoplastic aortic arch.

Abstract

Background: Forensic imaging was officially introduced in Israel in 2011. Religious and cultural opposition to autopsies prevails in most of the population in Israel.

Objectives: To examine the extent to which forensic imaging has been accepted as an adjuvant or partial replacement of forensic autopsy, particularly among those opposed to forensic autopsy.

Methods: The study was conducted in a pediatric population. Data were collected from the National Center of Forensic Medicine and Assaf Harofeh Medical Center during the 18 month period following the introduction of forensic imaging (group A). The data were compared to those of the previous 18 months (group B). The examined parameters were cases submitted, examined, autopsied or imaged depending on family consent.

Results: Consent to autopsy was similar in both groups (A = 56% vs. B = 54%). In group A, consent for imaging was 24% of all cases, and of those imaged 77% underwent autopsy. Of those examined externally only, 16% consented to imaging. For 7% of the total cases in group A, estimation of cause of death was based on virtopsy alone.

Conclusions: In a country with a high level of religious opposition to autopsy, it is a challenge to add forensic to the pediatric forensic investigation. Those consenting to forensic imaging are more likely to be those consenting to autopsy. Consent for forensic imaging only was given in 7% of cases. Greater efforts should be invested to educate and inform the public regarding the benefits of virtual autopsy and the importance of data acquired from forensic images. 

A thorough medical inquiry is included in every aviation mishap investigation. While the gold standard of this investigation is a forensic pathology examination, numerous reports stress the important role of computed tomography in the postmortem evaluation of trauma victims. To characterize the findings identified by postmortem CT and compare its performance to conventional autopsy in victims of military aviation mishaps, we analyzed seven postmortem CT examinations. Musculoskeletal injuries accounted for 57.8% of traumatic findings, identified by postmortem CT. The most frequent findings were fractures of the rib (47%), skull (9.6%) and facial bones (8.6%). Abnormally located air accounted for 24% of findings, for which CT was superior (3.5% detected by autopsy, 100% by postmortem CT, P < 0.001).  The performance of autopsy in detecting injuries was superior (autopsy detected 85.8% of all injuries, postmortem CT detected 53.9%, P < 0.001), especially in the detection of superficial lesions (100% detected by autopsy, 10.5% by postmortem CT, P < 0.001) and solid organ injuries (100% by autopsy, 18.5% by postmortem CT, P < 0.001), and in the detection of musculoskeletal injuries (91.3% for autopsy, 90.3% for postmortem CT, P = not significant). Postmortem CT and autopsy have distinct performance profiles, and although the first cannot replace the latter it is a useful complementary examination.

Background: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on the subject of gender-associated pathology in the elderly is also scarce.

Objective: To seek eventual gender-related differences in autopsies of elderly patients.

Methods: We analyzed the data extracted from a published report on 93 PMEs[1] performed at a geriatric hospital during the past 20 years.

Results: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P< 0.02). There was no significant difference in the gender distribution of the other diagnoses.

Conclusion: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.
