Endoscopic transthoracic sympathectomy is an effective form of treatment for palmar primary hyperhidrosis, is associated with a low morbidity, and can be performed as an ambulatory procedure.
Blast injuries are rare, and although blast-induced perforations of the bowel have been described in the past, the entity of a delayed perforation caused by an evolving injury has not been reported. We report three men injured by the explosion of a terrorist bombing in open air. They suffered primary blast injuries, which resulted in isolated perforations of the terminal ileum. They were operated at different times after the blast event. The resected specimens were examined under light microscopy. One patient was operated immediately, and had three perforations in the terminal ileum. In the other two patients, abdominal complaints appeared only 24 and 48 hours later. These two patients were found to have hematomas in the wall of the terminal ileum, and small perforations therein, with almost no contamination of the peritoneal cavity. On histological examination, there were small perforations with disruption of all intestinal layers. In the vicinity of the perforations, the mucosa was necrotic and disorganized. The submucosa showed edema and vascular thrombi, and at several points mucus was shown dissecting through the muscularis propria, thus creating minute microperforations. Because of the findings in these patients, we suggest a mechanism of evolving damage to the bowel wall and delayed perforation rather than delayed diagnosis, after blast injuries. We suggest that patients exposed to a significant blast should be watched carefully for at least 48 hours.
The latest wave of terrorism worldwide has seen significant use by terrorists of mundane, "low-technology" weapons, such as utility knives and civilian vehicles. How do the injuries they produce compare with that of more conventional terrorism mechanisms, such as use of firearms and explosives? We compare injury patterns of the most frequent terrorism-related injury mechanisms in an Israeli data set.Methods: This was a retrospective study of 1,858 patients hospitalized because of terrorism events, which were recorded in the Israeli National Trauma Registry between January 1997 and December 2016. The events were divided into 4 groups based on weapon used: explosions, shootings, stabbings, and vehicular attacks. The groups were compared in terms of injuries sustained, use of hospital resources, and clinical outcomes.Results: Explosion-related and vehicular terrorism resulted in a higher proportion of multiple injuries, whereas stabbings and shootings mostly led to isolated injuries. Victims of vehicular attacks had a high proportion of severe head injuries, whereas stabbing victims had a high volume of vascular injuries. All mechanisms involved significant damage to extremities; however, among stabbing victims injury was mainly to the upper extremities, whereas among vehicular attack victims it was mostly to the lower extremities. The overall injury severity of the compared groups was similar, leading to comparable levels of intensive care use and inhospital mortality. Certain similarities in victims' characteristics were observed between the shootings and stabbings and between explosions and vehicular attacks.
Conclusion:Despite differences between various terrorist attack mechanisms, the resulting injury severity and inhospital mortality are very similar, with stabbings and vehicular attacks causing injuries as serious as those caused by conventional weapons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
