Functional outcome and quality of life in victims of terrorist explosions as compared to conventional trauma.
Following trauma, the number of preventable deaths is low. Outcome should also be measured in terms of quality of life (QoL). Studies analyzing QoL in trauma patients have been published, but little is known about the long term QoL of victims of terrorist attacks. ⋯ Subjects present more emotional distortions, residual pain in the head region and a tendency towards a worsened perception of their own health and wellness. They also present symptoms associated to PTSD more frequently. The presence of symptoms associated to PTSD, depression or anxiety was an independent variable related to lower QoL in both groups.

To evaluate the pattern, demographics, circumstances behind events and patient outcome of civilian gunshot wounds (GSWs), we conducted a prospective review in a surgical department in Durban, South Africa over a period of 9 months. ⋯ This study provides evidence that the burden of GSW-related mortality and morbidity poses a substantial threat to the local public health. A national database for reporting all GSWs is recommended for proper assessment of the magnitude of the problem and to facilitate funding for research into injury prevention.

Hemobilia is a rare cause of upper gastrointestinal bleeding. More than 50% of hemobilia cases are related to iatrogenic trauma from hepatobiliary procedures, and needle biopsy of the liver represents the most common cause. A minority of hemobilia cases are due to hepatobiliary disorders such as cholangitis, hepatobiliary cancers, choledocholithiasis, and vascular abnormalities in the liver. The classic presentation of hemobilia is the triad of right upper quadrant (biliary) pain, obstructive jaundice, and upper gastrointestinal bleeding. We report a rare case of hemobilia caused by a spontaneous hepatic cyst rupture, where our patient presented without the classical symptoms, in the absence of therapeutic or pathological coagulopathy, and in the absence of spontaneous or iatrogenic trauma. ⋯ Hemobilia is an infrequent cause of upper gastrointestinal bleeding and rarely occurs due to hepatic cyst rupture. To the best of our knowledge, this is only the second case report in the literature that describes hemobilia due to hepatic cyst rupture. However, it is the first case in the literature of hemobilia due to hepatic cyst rupture in the absence of iatrogenic or spontaneous trauma, and in the absence of a spontaneous or pathological coagulopathy.

ReviewBiomedical engineering strategies for peripheral nerve repair: surgical applications, state of the art, and future challenges.
Damage to the peripheral nervous system is surprisingly common and occurs primarily from trauma or a complication of surgery. Although recovery of nerve function occurs in many mild injuries, outcomes are often unsatisfactory following severe trauma. Nerve repair and regeneration presents unique clinical challenges and opportunities, and substantial contributions can be made through the informed application of biomedical engineering strategies. ⋯ In this fight for time, degeneration of the distal nerve support structure and target progresses, ultimately blunting complete functional recovery. Thus, the most pressing challenges in peripheral nerve repair include the development of tissue-engineered nerve grafts that match or exceed the performance of autografts, the ability to noninvasively assess nerve damage and track axonal regeneration, and approaches to maintain the efficacy of the distal pathway and targets during the regenerative process. Biomedical engineering strategies can address these issues to substantially contribute at both the basic and applied levels, improving surgical management and functional recovery following severe peripheral nerve injury.

The neuropathic pain syndrome is complex. Current drugs to treat neuropathic pain, including anticonvulsivants and antidepressants, fail in up to 40-50% of the patients, while in the rest of them total alleviation is not normally achieved. Increased research advances in the neurobiology of neuropathic pain have not translated in more successful pharmacological treatments by the moment, but recent progress in the experimental methods available for this purpose could result in significant advances in the short term. ⋯ Following this strategy, neurotrophic factors such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) have been postulated as potential pharmacological targets to treat neuropathic pain. In addition, during the last few years, strong scientific evidences point to novel neurotrophic factors, such as pleiotrophin (PTN), as important factors to limit neuropathic pain development because of their remodeling and angiogenic actions in the injured area. This review focuses on recent research advances identifying new pharmacological targets in the treatment of the cause, not only the symptoms, of neuropathic pain.
