Lead Toxicity From Intradiscal Retained Bullet Fragment: Management Considerations and Recommendations.

BACKGROUND: Lead toxicity (plumbism) secondary to retained lead missiles in synovial joint spaces is a rare complication after gunshot injuries. Management of lead missiles in the intradiscal space regarding potential lead toxicity is less certain. CASE DESCRIPTION: We reviewed the literature regarding lead toxicity secondary to intradiscal bullets particularly concerning incidence, management, and outcomes. A lack of high-quality published data precludes a meta-analysis from taking place. Only four reports of lead toxicity secondary to missiles in the intradiscal space have been published. Including an additional case presented in this report, our review of the literature has led us to make several management recommendations, largely based on both the available literature and our current report. CONCLUSIONS: First, there is insufficient evidence for removing retained lead missiles solely to mitigate the risk of lead toxicity. Second, chelation therapy in addition to surgical removal of the lead source is a valuable adjunct in the perioperative period and should be undertaken with the assistance of medical toxicology. Third, a retained missile does not mandate a simultaneous stabilization procedure in lieu of other indications based on the data available at this time.

Index Use of Smoflipid in a Tertiary Intestinal Rehabilitation and Transplantation Program.

Long-term parenteral nutrition (PN) may be complicated by PN-associated liver disease (PNALD), and some studies suggest an association between the use of soy-based fat emulsions and PNALD development. Patients' liver function typically improves and PNALD resolves after reducing or stopping a soy-based fat emulsion, and thus lipid minimization has been the primary strategy for managing PNALD in many intestinal rehabilitation programs. However, fat emulsions often cannot be stopped entirely, leading some patients to develop PNALD even after lipid reduction strategies have been implemented. Smoflipid emulsion (Kabi-Fresenius, Bad Homburg, Germany), a balanced mixture of soybean oil, medium-chain triglycerides (MCTs), olive oil, and fish oil, was recently approved by the Food and Drug Administration for use in the United States as an equivalent alternative to Intralipid (Baxter Healthcare Corporation, Deerfield, IL). In several pediatric studies, patients who received Smoflipid had significantly lower serum bilirubin levels than those who received Intralipid. In this case report, we present a patient who developed severe PNALD with subsequent resolution after 20 weeks on Smoflipid.

Severe Systemic Lead Toxicity Resulting From Extra-Articular Retained Shrapnel Presenting as Jaundice and Hepatitis: A Case Report and Review of the Literature.

INTRODUCTION: Despite greater than 60,000 nonfatal firearm injuries per year in the United States, retained shrapnel is a relatively rare cause of systemic lead toxicity with less than 100 cases reported in the medical literature since 1867. While intra-articular retained shrapnel as a cause of lead toxicity is well-described, extra-articular fragments are less well known to cause symptomatic disease. CASE REPORT: A 31-year-old man initially presented with abdominal pain, constipation, jaundice, and elevated liver transaminases approximately 3 weeks after suffering a left lower extremity injury during athletic activity. The patient was found to have steatohepatitis after extensive inpatient and outpatient gastroenterological workup to include upper and lower endoscopy, liver ultrasound, and biopsy of the liver to confirm the diagnosis. Imaging was incidentally notable for retained gunshot in the left flank and large shell fragment containing seroma in the left thigh. The patient was initially discharged with improved pain, but later presented to a primary care clinic with weight loss and continued pain. This was followed by a subsequent progression to diffuse weakness, ultimately resulting in an inability to ambulate. The patient was readmitted to a tertiary care medical center, 3 months after the initial presentation. Physical exam was then notable for 70-lb weight loss from initial admission and diffuse peripheral weakness with global muscle atrophy. Following a broad differential workup, he was found to have a blood lead level of 129 µg/dL, and hemoglobin of 7.7 g/dL with basophilic stippling on peripheral smear. The patient was transferred to the intensive care unit for chelation therapy with dimercaprol and calcium ethylenediaminetetraacetic acid. Lead levels initially decreased, but rose when patient was transitioned to oral therapy with succimer. Surgery was consulted for removal of multiple retained fragments, which were analyzed by the Joint Pathology Center and found to contain lead. The patient's motor function gradually improved on oral chelation and he was discharged to a subacute rehabilitation facility. CONCLUSION: This complex case describes a rare cause for a relatively common clinical presentation, jaundice and hepatitis, and reinforces the importance of longitudinal follow up and reassessment of a patient with an unknown illness and worsening clinical condition. Diagnosis of systemic lead toxicity is challenging because of its protean clinical manifestations, and relative rarity with the advent of strict environmental lead controls and decrease in lead-based paint and industrial products. Furthermore, extra-articular lead remains a rare cause of systemic toxicity, and the surgical standard of care has been to not remove these fragments in gunshot victims. This case adds to a small amount of evidence that lead screening may be of value in selected patients with extra-articular retained shrapnel, especially those with seroma and osteophyte formation in the wound.

[CHARACTERISTICS OF ANTIBIOTICORESISTANCE OF MICROFLORA IN A COMBAT (THE GUN-SHOT ANO THE MINE-EXPLOSION) WOUNDS OF THE EXTREMITIES].

Abstract Results of bacteriological investigations of a gun-shot and a mine-explosion woundings of the extremities were analyzed in Military-Medical Clinical Centres (MMCC) of Kyiv, Lviv and Vinnytsya. Spectrum of the allotted microorganisms and profile of their antibioticoresistance were disclosed. The patterns of resistance were determined in accordance to offering of international experts of European Committee on Antimicrobial Susceptibility Testing (EUCAST). Dominating microflora in a Chief MMCC (Kyiv) and MMCC of a Western Region (Lviv) were various species of the Enterobacteriaceae and P. aeruginosa families, while in MMCC of a Central Region (Vinnytsya)--a gramm-negative non-fermentative bacilli of the Acinetobacter genus and Pseudomonas genus. The majority (79.5%) of isolates were characterized by polyresistance for antibiotics. Maximal quantity of strains with a widened spectrum of resistance was revealed in 2 - 3 weeks after a wounding--in 71.4 and 96.9% accordingly.

Zinc Deficiency With Dermatitis in a Parenteral Nutrition-Dependent Patient Due to National Shortage of Trace Minerals.

The shortages of intravenous drugs remains critical, with sterile injectables accounting for 80% of the approximately 300 shortages. The impact is being felt in patients dependent on parenteral nutrition (PN), and severe deficiencies are becoming more commonplace. We report here a man who developed severe zinc deficiency, manifesting as a painful desquamative rash, due to an inability to obtain multi-trace element additives for his PN.

Vitreoretinal surgery for shotgun eye injuries: outcomes and complications.

PURPOSE: To analyse the postoperative anatomic and functional outcomes in addition to complications after vitreoretinal surgery for patients with shotgun eye injuries related to hunting accidents. MATERIALS: Retrospective review of the clinical records of all cases of shotgun eye injuries presented between January 2000 and January 2011 and with a minimum follow-up of 1 year. Collection of demographics, type of injury, choice of management, complications and final surgical success with final visual acuity is reported. RESULTS: Twenty eyes of 19 patients (all male) with a mean age of 36.1 years (range 16-60 years) were included in the study. Mean postoperative follow-up was 47.5 months (range 15-118 months). Best corrected visual acuity (BCVA) at presentation ranged from perception of light to 20/200. Ten eyes had a penetrating injury and 10 others had a perforating injury. All the eyes underwent an initial vitrectomy and the intraocular pellet was removed in all the 10 penetrating injuries. Concurrent cataract surgery was performed in 12 cases, internal tamponade was used in 15 cases and a supplemental encircling scleral buckle was inserted in 12 cases. One additional vitreoretinal surgery was required in seven cases (35%) and two additional surgeries required in two other cases (10%). At last follow-up BCVA ranged from NPL to 20/20 and was 20/100 or better in 10 eyes (50%). All patients had a flat retina except for two cases (10%) that developed severe proliferative vitreoretinopathy. CONCLUSION: These results suggest that vitreoretinal surgery can offer good visual rehabilitation in patients with shotgun eye injuries.

Systemic plumbism following remote ballistic injury.

We report an unusual case of systemic lead poisoning, i.e., plumbism, following a remote gunshot injury to the right femur. Plumbism is a rare side-effect of penetrating projectiles and has been shown to be directly related to the degree of ballistic fragmentation, as well as to the impact location, with intra-synovial, intra-osseous, head, spine and maxillofacial injuries having the highest correlation. Our patient, a 44-year-old male, presented to the ER with a 3-week history of mid epigastric cramping abdominal pain and intermittent vomiting as well as mild mental status changes. Abdominal radiographs and ultrasound were noncontributory. Laboratory findings were notable for underlying microcytic anemia with basophilic stippling observed on peripheral blood smear. Serum iron studies were normal. Lead levels were found to be elevated at 306 µg/dl. Prior EGD had demonstrated mild erosive gastritis with subsequent multiple negative gastric lavages. The patient's past medical history was notable for a previous gunshot injury to the right femur with open fracture 2 years previously. Radiographs of the proximal right lower extremity, subsequent ultrasound and CT demonstrated an uncomplicated healed fracture of the mid right femoral diaphysis with an adjacent partially cystic lesion, an approximately 7-cm collection in the medial soft tissues containing internal ballistic fragments. Mottled surrounding capsular density was observed with mural calcific and micrometallic fragments. Systemic plumbism was suspected in relation to the remote ballistic injury and chelation therapy was initiated. Following surgical removal of the encapsulated fluid collection, systemic lead levels were observed to decline precipitously. The abdominal and CNS symptoms resolved in due course and the patient was discharged on oral chelation therapy.

Lead toxicity and management of gunshot wounds in the lumbar spine.

INTRODUCTION: Gunshot wounds are one of the commonest causes of spinal injury. Management of these patients differs from other blunt trauma injuries to the spine. We present a case of a gunshot wound to the lumbar spine that occurred in 1985 which was treated non-operatively. METHODS: In the last 10 years, the patient was admitted multiple times for confusion and lead toxicity with blood levels over 100 µg/dl. Inpatient chelation therapy was implemented. After multiple recommendations for surgery, the patient agreed to have as much of the bullet removed as possible. The patient successfully underwent decompression and fusion from both anterior and posterior approaches. Lead levels subsequently declined. CONCLUSION: The purpose of this paper is to show a case of a gunshot wound to the spine that ultimately caused plumbism and required surgery. Technical aspects of the surgery are described as well as pre- and post-procedural imaging. Recommendations for the general management of spine gunshot wounds are also described.

Severe facial and ocular injuries from a potato gun.

Potato guns or spud guns are homemade firearms built primarily for recreational use. Information on how to make these can be found easily by searching the topic on the Internet. There is a surplus of Web sites dedicated to providing information to anyone looking to make one of their own. We present an interesting case that illustrates the extent of trauma, which can be caused by these dangerous devices. Despite the growing information available for consumers of any age, there is little information for clinicians regarding these devices and the serious threat of injury that they pose. The current trauma and injury databases, unfortunately, do not gather data pertaining specifically to these devices. In addition, because they are homemade and primarily built for recreational purposes, their use is not controlled or regulated by the government. It is important for clinicians to be aware of homemade firearms such as potato guns, be prepared to manage injury from these devices, and as with other weapons or firearms provide patients and families with the appropriate anticipatory guidance.

[Pulmonary resection and ECMO: A salvage therapy for penetrating lung trauma]. / Lobectomie d'hémostase et ECMO : une association salvatrice après plaie pénétrante du thorax.

The majority of chest penetrating trauma patients are successfully managed with tube thoracostomy and general supportive measures. Pulmonary resection for hemorrhagic shock is rarely required after trauma to control bleeding. Both pulmonary injury and massive blood transfusion can lead to acute respiratory distress syndrome (ARDS). The mortality rate in these patients reaches up to 40% despite advanced ventilatory treatment. The use of extracorporeal membrane oxygenation (ECMO) can be started as rescue therapy. We report a case of 24-year-old man with major hemorrhagic shock with cardiac arrest and ARDS after traumatic penetrating lung injury that was successfully treated with pulmonary resection and ECMO.

Feasibility, reproducibility, risks and benefits of face transplantation: a prospective study of outcomes.

Composite tissue allotransplantations can be indicated when autologous transfers fail to restore human appearance. We report the reproducibility, difficulties, serious adverse events and outcomes of our patients. Five patients were included in a registered clinical research protocol after thorough screenings assessed by an independent expert committee systematically discussing the alternative options. One patient suffered from plexiform neurofibromas, two from third degree burns and two from gunshot injuries. They were included on a national waiting list with a dedicated face procurement procedure. Transplants were harvested from heart beating brain-dead donors before other tissues and organs. Induction immunosuppressive therapy included antithymocyte globulins, steroids, mycophenolate mophetil and tacrolimus. Maintenance therapy included the last three ones associated with extracorporeal-photopheresis. Four patients were transplanted with 7- to 38-month follow-up. One could not due to multiple panel reactive antibodies after 18 months on waiting list. Acute cellular rejections were controlled by conventional treatment. Opportunistic infections affected all patients and lead one patient to die two month after the transplantation. Voluntary facial activity appeared from 3 to 5 month. Face transplantation has been reproducible under conventional immunosuppression. Major improvements in facial aesthetic and function allowed patients to recover social relations and improved their quality of life.

Management of a mandibular fracture accompanying a gunshot wound.

Gunshot injuries of the mandible can result in high rates of complications, especially in cases of bone loss. A fractured mandible accompanying a gunshot wound almost always has an external wound; the fracture is always compound and comminuted. Sometimes management of these injuries may require multiple surgical interventions. In this clinical report, treatment of a patient, who had a mandibular fracture due to a gunshot wound, is presented.A 52-year-old man with a mandibular fracture in the right mandibular body accompanying a gunshot wound was operated on. Owing to a nonunion, a second surgery was performed using reconstruction plates after hyperbaric oxygen treatment. Healing was uneventful after the second surgical intervention.

Sir Victor Horsley's contributions to the study and treatment of gunshot wounds of the head.

Sir Victor Horsley'S many contributions to neurological surgery include experimental and clinical studies of gunshot wounds (GSW) of the head. Horsley's publications from 1894 to 1897 and 1914 to 1915 on GSWs were reviewed. Horsley described GSWs in animal and clay models, illustrating characteristics of the primary missile tract and secondary cavitation. A transcranial GSW model in 67 dogs related intracranial damage to the projectile's velocity and sectional area, producing a marked sudden increase in intracranial pressure that presumably "tunneled" to the medullary respiratory and cardiac centers. If the resultant sudden apnea was treated with artificial respiration and prompt surgical decompression, the animal often survived. In these animal experiments, Horsley clearly described increased intracranial pressure, hypertension, and bradycardia-later recognized as the Cushing response or triad. With the onset of World War I, Horsley again reviewed the ballistics of military weaponry, emphasizing projectile spin and velocity as the main wounding mechanisms. He was outspoken against the "wicked tradition" of neglecting cranial GSWs and personally treated cases with aggressive respiratory support and prompt decompression of devitalized tissue. Horsley's contributions to the experimental and clinical aspects of GSWs to the head are consistent with his other important contributions to neurosurgery and have largely stood the test of time.

[Cranial surgery in XVIIth century Vienna: a case from Evliya Celebi's Book of Travel]. / XVII. Yüzyil viyana'sinda kafatasi cerrahisi: Evliya Celebi seyahatnamesi'nden bir olgu.

Book of Travel (Seyâhatnâme) of Evliya Celebi has always been an invaluable resource for history and ethnography researchers. And it is found out via our paper about "neurosurgical operation" that the above mentioned work can be studied for researches concerning the history of medicine. It is seen that Evliya Celebi reports a neurosurgical operation for curing a gunshot wound, and that he is very well aware of medical paradigm of his era. And he reports the situation without departing from the work and the dominant literary language of the work and without passing over the technical details, and he also does not get lost in the details. He also reports all the general stages of the operation by giving all the techniques and methods of his era. This work can also be considered as an evidence for the origins of western medicine and surgery in the east. Because it is observed that eastern scientists such as Ibn Sina and Zehravi have been referenced for the situation the surgeon took care of, the methods the surgeon used and the stages during the operation.

Infection prophylaxis of gunshot wounds using probiotics.

OBJECTIVE: To report a new method of surgical infection prophylaxis for postoperative gunshot wounds to the extremities. METHOD: Gunshot wounded animals were divided into three groups: treatment (probiotic Sporobacterin), antibiotic (cephalosporin cefamezin) and control (no treatment). Histological studies of wound-bed tissue were taken on days 1, 3, 5 and 10 of the study. RESULTS: The probiotic administered per os was more effective than antibiotics for prophylaxis of surgical infection. CONCLUSION: The probiotic's effect is based on the natural defence mechanism activated after injury--the bacterial translocation of saprophytic bacteria from the gut to the wound. DECLARATION OF INTEREST: None.

[Surgical infection in combat injuries of extremities]. / Khirurgicheskaia infektsiia pri boevykh povrezhdeniiakh oporno-dvigatel'nogo apparata.

A retrospective analysis was performed of treatment of 1612 patients with gunshot fractures of long bones of the extremities wounded in the Republic of Afghanistan and Chechen Republic. Under study was the infrastructure of the gunshot fractures, general and local factors responsible for the development of suppurations. A angioneurodystrophy theory of pathogenesis of gunshot osteomyelitis is proposed. The level of proinflammatory cytokines was determined in blood serum and wound discharge for the early diagnosis of purulent complications. An algorithm of the diagnostic search was developed with using modern radio- and electrophysiological methods. The standards of general and local treatment are proposed for different stages and spread of the purulent process.

Wound shock: a history of its study and treatment by military surgeons.

The treatment of wounds has received considerable attention from the time of the Trojan War. However, it was not until the American Civil War that shock was described as an entity distinct from the wounds themselves and that efforts were directed at more than just treatment of the wound. The need for fluid resuscitation in the treatment of hemorrhagic shock was first recognized in the Spanish American War, as was the association of sepsis with shock. World War I showed the need for blood in the treatment of "wound shock," a lesson that had to be relearned in World War II through bitter experience. Studies in the Korean War described the concept of disseminated intravascular coagulation and multiple organ failure, and the existence of disseminated intravascular coagulation was confirmed by studies in Vietnam. The treatment of hemorrhagic shock is now very effective, but the treatment of traumatic and septic shock remains unsatisfactory.

[Regional circulation in gunshot wounds of the ankle joint and foot]. / Regionarnoe krovoobrashchenie pri ognestrel'nykh raneniiakh golenostopnogo sustava i stopy.

Problems of treatment of battle injuries of the ankle joint and foot are discussed. These injuries are characterized with severe disturbances of regional circulation and microcirculation causing hypoxia and metabolic disorders both in soft tissues and in bones. Digital substraction angiography (DSA) was used in 7 wounded (7.53%) of all patients with battle injuries of the foot and ankle joint. Combined treatment including surgery, drugs, physical and exercise therapy, hyperbaric oxygenation was used in all the patients. Prolonged intraarterial infusion of drugs was carried out in 4 of 7 patients. It is concluded that early evaluation of regional circulation permits to clarify expediency of applied combined treatment. Injury of three arteries is the indication for amputation, but even one functioning artery enables use of combined therapy with intraarterial infusion for extremity salvage.
