[Antimicrobial anti-inflammatory photodynamic and light-emitting-diode phototherapy of the consequences of the gunshot and mine-blast injury to the face, head, and neck including damage to the ENT organs]. / Antimikrobnaia protivovospalitel'naia fotodinamicheskaia i svetodiodnaia fototerapiia posledstvii ognestrel'noi i minno-vzryvnoi travmy golovy i shei.

The objective of the present study was the enhancement of the effectiveness of the treatment of the consequences of the gunshot wounds and mine-blast injuries inflicted to the face, head, and neck encountered in the otolaryngological practice as well as the prevention of the formation of the large demarcation areas in the injured tissues and the preparation of these tissues for the further restorative treatment. Anti-microbial and anti-inflammatory photodynamic therapy (PDT) as well as light-emitting-diode (LED) phototherapy were carried out in 20 patients who suffered gunshot wounds and mine-blast injuries to the face, head, and neck. The photodynamic therapy was performed with the use of an aqueous solution of methylene blue at a concentration of 0.1%, the 'Alod-1' infrared laser ('Granat' modification, Russia), and the 'AFS-Solaris' light-emitting diode-based phototherapeutic apparatus (Russia). The analysis of the results of the study has demonstrated the high efficiency of the proposed approach that made it possible to prevent the development of severe septic complications, reduce the amount of drug therapy, significantly shorten duration of the treatment, and create the conditions for the earlier rehabilitation and further plastic and cosmetic restoration of the tissue structures.

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.

Quadriparesis Caused by Lead Poisoning Nine Years After a Gunshot Wound With Retained Bullet Fragments: A Case Report.

Lead toxicity in adults is characterized by nonspecific symptoms of abdominal pain, vomiting, constipation, fatigue, and weight loss. We present a case of severe lead toxicity that developed subacutely, causing quadriparesis 9 years after a gunshot wound with retained bullet fragments. The onset of symptoms may have been related to the development of a pseudocyst. The long interval between the gunshot wound and the onset of symptoms contributed to a delay in suspecting that the retained bullet was a source of lead toxicity. The patient's symptoms gradually improved after chelation therapy, removal of the bullet fragment, and an extended program of acute inpatient rehabilitation. LEVEL OF EVIDENCE: V.

Retained Lumbar Bullet: A Case Report of Chronic Lead Toxicity and Review of the Literature.

BACKGROUND: Lead toxicity from retained bullet fragments is difficult to both predict and diagnose, but important to treat early, given the potential severity of disease. Blood lead levels > 25 µg/dL and 40 µg/dL are considered toxic in children and adults, respectively. Symptoms may range from nonspecific constitutional symptoms to seizures and coma. Chelation is the mainstay therapy for lead poisoning and levels to treat depend on patient age, blood lead levels, and the presence of symptoms. CASE  REPORT: We present the case of a woman with symptoms of severe lead toxicity from 20-year-old retained bullet fragments. She had been seen by multiple providers for evaluation of each symptom, but a unifying diagnosis had not been found. After identifying this complication, she was treated appropriately and more serious complications were prevented. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We present this case to increase awareness among emergency physicians of lead toxicity in patients with a seemingly unrelated constellation of symptoms and a history of a previous gunshot wound with retained bullet or bullet fragments.

Nausea, Vomiting, and Weight Loss in a Young Adult Patient With a History of a Gunshot Wound.

Assessing victims of gunshot wounds with retained bullets/bullet fragments for lead toxicity is not always considered until the patient develops signs and symptoms of toxicity. We discuss the case of a 19-year-old young man who received a diagnosis of chronic lead toxicity (serum lead concentration 51 µg/dL) 5 weeks after a hunting accident. Extensive wound debridement occurred following the accident; however, lead toxicity was not diagnosed until after his fourth emergency department visit. Oral chelation therapy was required for the management of his lead toxicity.

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.

Traumatic laceration of the cisterna chyli treated by lymphangiography and percutaneous embolization.

Lymphangiography and percutaneous embolization has been described for the treatment of thoracic duct injury, usually occurring in the postsurgical period. We report a case of a traumatic gunshot-induced massive chylothorax. Inguinal lymphangiogram was performed demonstrating the site of injury at the cisterna chyli. The cisterna chyli was successfully accessed via a percutaneous approach, and embolization was performed. Chylothorax immediately resolved after two rounds of embolization. Although lymphangiography has been traditionally challenging and cumbersome, because of the need for pedal lymph access, the recent use of inguinal lymphangiography has made this technique more practical. Techniques used for embolization of the thoracic duct may be applied to the cisterna chyli, which is much more challenging to treat surgically.

[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.

Treatment of chronic lead toxicity with succimer: a case series of 2 adults with retained lead shotgun fragments.

UNLABELLED: Few recommendations exist for management of chronic lead toxicity in instances when the source of lead exposure cannot be removed. CASES: We describe 2 patients who had shotgun wounds resulting in multiple retained lead pellets. They developed elevated blood lead levels and were treated with 2 weeks of high-dose oral succimer before being placed on maintenance oral succimer therapy with the goal of sustaining suppressed lead levels. DISCUSSION: Retained lead pellets have been associated with increasing blood lead levels over time. Chronic lead toxicity can cause significant morbidity. Few treatments for lead toxicity are available, and there is scarce data on maintenance therapy for patients who have large numbers of retained shotgun pellets. CONCLUSIONS: This case series documents 2 patients who continue on maintenance oral chelation therapy with succimer in an effort to prevent the sequelae of chronic lead toxicity by maintaining blood lead levels less than 20 µg/dL.

Lead poisoning from a gunshot wound.

Lead poisoning from gunshot wounds is unusual. Awareness of this rare but serious complication can guide the physician in making a prompt diagnosis. We present a case of a 30-year-old male who had a remote history of a gunshot wound in the right knee and presented with right knee pain. Plain film showed intrarticular invasion of the bullet fragments. He was also found to have microcytic anemia with high blood lead levels. Chelation therapy was immediately started, followed with surgical removal of the bullet fragments. Lead intoxication is a rare but fatal complication of gunshot wounds. After a timely diagnosis, chelation therapy should be immediately started.

Lead poisoning due to gunshot bullet in contact with cerebrospinal fluid: case report.

CONTEXT: Lead poisoning due to retained gunshot bullets is a well-known clinical problem that is fairly frequently described in the literature. The risk factors for this occurrence relate mainly to whether the lead bullet is in contact with the joint fluid or cerebrospinal fluid (CSF). The treatment for these cases entails chelation therapy while symptoms are shown and definitive surgical removal of the bullet as a potential source of lead. The aim of this paper is to describe a clinical case of lead poisoning due to a retained gunshot bullet in contact with CSF. CASE REPORT: A 42-year-old male was hit by gunshot bullets during a holdup, and one of them was retained in the spinal cord. Six years later, he developed intense low back pain and underwent laminectomy. Nine years later, he then underwent arthrodesis on L5-S1, but he developed intense abdominal pain after the surgical procedure. For five years, he was treated with calcium versenate in five-day cycles, with a good response. The chelation therapy cycles showed great efficacy during symptomatic periods, thus reducing the symptoms and signs of poisoning and promoting great amounts of lead excretion, thereby reducing the total lead burden responsible for the symptoms. Fortunately, over the last four years, the symptoms have improved and the urine levels of aminolevulinic acid (ALA) have declined, to reach complete normalization. This shows that a healing process is probably taking place on the spinal wound, thereby isolating the bullet fragments from CSF contact.

Hypnotic analgesia for combat-related spinal cord injury pain: a case study.

A U.S. Army soldier stationed in Iraq developed myriad pain problems after sustaining a high-level spinal cord injury (SCI) from a gunshot wound. These problems were negatively impacting his ability to participate fully in his physical rehabilitation and care. Ten sessions of self-hypnosis training were administered to the patient over a 5-week period to help him address these problems. Both the patient and his occupational therapist reported a substantial reduction in pain over the course of treatment, which allowed the patient to actively engage in his therapies. Six months post treatment, the patient reported continued use of the hypnosis strategies taught, which effectively reduced his experience of pain. This case study demonstrates the efficacy of hypnotic analgesia treatment for U.S. military veterans who are experiencing pain problems due to traumatic or combat-related SCIs.

Lead poisoning due to gunshot bullet in contact with cerebrospinal fluid: case report / Intoxicação por chumbo devida a projétil de arma de fogo em contato com o líquido cefalorraquidiano: relato de caso

CONTEXTO: A intoxicação por chumbo devida a projétil retido em ferimento por arma de fogo é uma complicação já conhecida e descrita na literatura. O risco de intoxicação endógena por chumbo está associado ao contato do projétil com o líquido sinovial ou líquido o cefalorraquidiano. O tratamento requer terapia de quelação e retirada cirúrgica do projétil como tratamento definitivo. Este artigo descreve caso clínico de paciente que desenvolveu intoxicação por chumbo devida a projétil retido em contato com líquido cefalorraquidiano. RELATO DE CASO: Paciente masculino, 42 anos, foi baleado durante assalto e teve projéteis que se alojaram no abdômen, perna direita e coluna lombo-sacra. Seis anos depois, desenvolveu intensa lombociatalgia e foi submetido a laminectomia. Nove anos após o acidente, foi submetido a artrodese de L5-S1, quando foi tentada a retirada do projétil, sem sucesso, desenvolvendo no pós-operatório intensa dor abdominal. Foi então feito diagnóstico de intoxicação por chumbo, que foi tratada com gluconato de cálcio, com boa resposta. Durante os cinco anos seguintes, fez ciclos de quelação com ácido etilenodiaminotetracético (EDTA) cálcico, com boa evolução. Os ciclos de quelação mostraram grande eficácia na redução dos sinais e sintomas da intoxicação, promovendo um grande aumento da excreção de chumbo e reduzindo a carga corpórea total de chumbo responsável pelos sintomas. Nos últimos quatro anos, apresentou melhora dos sintomas de intoxicação, com diminuição dos níveis de ALA urinário até a normalização, mostrando que provavelmente houve um processo de cicatrização da lesão, isolando os fragmentos de chumbo do contato com o líquor.

Structure and function in acquired prosopagnosia: lessons from a series of 10 patients with brain damage.

Acquired prosopagnosia varies in both behavioural manifestations and the location and extent of underlying lesions. We studied 10 patients with adult-onset lesions on a battery of face-processing tests. Using signal detection methods, we found that discriminative power for the familiarity of famous faces was most reduced by bilateral occipitotemporal lesions that involved the fusiform gyri, and better preserved with unilateral right-sided lesions. Tests of perception of facial structural configuration showed severe deficits with lesions that included the right fusiform gyrus, whether unilateral or bilateral. This deficit was most consistent for eye configuration, with some patients performing normally for mouth configuration. Patients with anterior temporal lesions had better configuration perception, though at least one patient showed a more subtle failure to integrate configural data from different facial regions. Facial imagery, an index of facial memories, was severely impaired by bilateral lesions that included the right anterior temporal lobe and marginally impaired by fusiform lesions alone; unilateral right fusiform lesions tended to spare imagery for facial features. These findings suggest that (I) prosopagnosia is more severe with bilateral than unilateral lesions, indicating a minor contribution of the left hemisphere to face recognition, (2) perception of facial configuration critically involves the right fusiform gyrus and (3) access to facial memories is most disrupted by bilateral lesions that also include the right anterior temporal lobe. This supports assertions that more apperceptive variants of prosopagnosia are linked to fusiform damage, whereas more associative variants are linked to anterior temporal damage. Next, we found that behavioural indices of covert recognition correlated with measures of overt familiarity, consistent with theories that covert behaviour emerges from the output of damaged neural networks, rather than alternative pathways. Finally, to probe the face specificity of the prosopagnosic defect, we tested recognition of fruits and vegetables: While face specificity was not found in most of our patients, the data of one patient suggested that this may be possible with more focal lesions of the right fusiform gyrus.

Fracture of the coronoid and pterygoid processes by firearms: case report.

A rare case of fracture of the coronoid and the pterygoid process caused by firearms is described. A 28-year-old male was hit by a bullet in the face, resulting in restricted mouth opening, difficulty in chewing and pain when opening the mouth. Clinical examination revealed a perforating wound in the right parotid region and a similar wound on the left side of the same region. A CT scan showed comminuted fracture of the left coronoid process and bilateral comminuted fracture of the pterygoid processes. Treatment was conservative, speech therapy was conducted and it was successful. Details of the clinical signs, radiology (3D-CT scan), treatment and follow-up are presented.

Complementary and alternative medicine approaches to pain management.

This article argues for and illustrates incorporating complementary and alternative medicine (CAM) interventions into pain treatment plans. Two CAM treatments, cranial electrotherapy stimulation (CES) and self-hypnosis training, are offered in a multidisciplinary pain treatment program. Because these interventions focus on pain relief, they may be of particular interest to patients who have chronic pain who begin treatment with a primary interest in pain reduction. Two cases that illustrate the clinical application of CES and self-hypnosis are presented. When effective, these interventions can help patients have greater confidence in treatments offered by psychologists for pain management and may help make them more open to participating in other psychological interventions that have established efficacy for pain management (e.g., cognitive-behavioral therapy). Because of their brevity, these treatments also can be offered alone to patients who may not have the resources or time to participate in more time-intensive treatment.
