Electronic cigarettes are increasingly popular as a supposed safer alternative to tobacco cigarettes or a smoking cessation tool. Research and debate have focused primarily on possible adverse effects caused by the inhaled aerosol produced by electronic cigarettes and on smoking cessation efficacy. Few reports in the medical literature describe injuries secondary to device malfunction. We present a case of electronic cigarette explosion, with a projectile fracturing the patient's right naso-orbital-ethmoid complex and anterior and posterior frontal sinus tables, with frontal sinus outflow tract involvement...

Occupational inhalation of dust, such as crystalline silica, for prolonged periods in the workplace leads to fibrotic lung diseases worldwide. The mechanisms underlying the diseases are unknown, so that no effective treatment exists for these conditions. We found elevated levels of follistatin like 1 (FSTL1) in serum from patients with silicosis and in lungs from silica-induced mouse model. The induced Fstl1 regulated inflammation response via activation of nod-like receptor family, pyrin domain containing 3v (NLRP3) inflammasome-mediated IL-1β production from macrophages...

INTRODUCTION: Burns cause physiologic changes in multiple organ systems in the body. Burn mortality is usually attributable to pulmonary complications, which can occur in up to 41% of patients admitted to the hospital after burn. Patients with preexisting comorbidities such as chronic lung diseases may be more susceptible. We therefore sought to examine the impact of preexisting respiratory disease on burn outcomes. METHODS: A retrospective analysis of patients admitted to a regional burn center from 2002-2012...

Introduction: Cigarette smoking (CS) remains a major public health concern and has recently been associated with an increased risk of developing acute respiratory distress syndrome (ARDS). Bronchoalveolar lavage (BAL) experiments in human volunteers have demonstrated that active smokers develop increased alveolar-epithelial barrier permeability to protein after inhaling lipopolysaccharide (LPS). Here we tested the hypothesis that short-term whole-body CS exposure would increase LPS-induced lung edema in mice...

The purpose of this study is to determine the incidence of sinusitis in mechanically ventilated burn victims and to examine if the presence of inhalational injury increases the likelihood of developing sinusitis. The authors hypothesize that the incidence of sinusitis will be increased in burn victims who have concomitant inhalational injury. A retrospective chart analysis was performed on all patients who were admitted to the Nathan Speare Regional Burn Treatment Center over a 24-month time frame. Patients who were mechanically ventilated for greater than 24 hours were then selected, resulting in a total of 137 patients for analysis...

BACKGROUND: Remimazolam is an ester-based short-acting benzodiazepine currently in clinical trials for IV administration. This study explored the feasibility of delivering remimazolam alone and as an adjunct to remifentanil via inhalation in rodent models. METHODS: Mice were exposed to remimazolam via inhalation; sedation was assessed using time to movement outside a set perimeter. Rats were also exposed to remimazolam aerosol alone and in combination with inhaled remifentanil, and analgesia was quantified by using a tail flick meter...

BACKGROUND: The deficit of donor sites in major burns over 50% of the total body surface area has necessitated the application of methods besides traditional meshed autografting to achieve definitive skin cover. The Meek micrografting technique was introduced at this hospital in 2011, especially in the absence of a reliable source of deceased donor allograft skin. The purpose of this study was to evaluate this strategy with reference to its technical execution, efficacy and indications in the context of major paediatric burn surgery...

The present study investigated the effects of diesel exhaust (DE) on an experimental model of bleomycin (BLM)-induced lung injury and fibrosis in mice. BLM was intravenously administered to both Nrf2(+/+) and Nrf2(-/-) C57BL/6J mice on day 0. The mice were exposed to DE for 56 days from 28 days before the BLM injection to 28 days after the BLM injection. Inhalation of DE induced significant inhibition of airway clearance function and the proinflammatory cytokine secretion in macrophages, an increase in neutrophils, and severe lung inflammatory injury, which were greater in Nrf2(-/-) mice than in Nrf2(+/+) mice...

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans that tends to affect immunocompromised individuals. The fungi are mostly acquired by inhalation, which leads to an initial pulmonary infection. Later, other organs - such as the central nervous system and the skin - can be affected by hematogenous spread. In addition, cutaneous contamination can occur by primary inoculation after injuries (primary cutaneous cryptococcosis), whose diagnosis is defined based on the absence of systemic involvement...

BACKGROUND Recognition and appropriate management of right ventricular (RV) infarction is essential, as RV injury increases mortality and substantially alters management during acute coronary syndrome. We report a case of RV infarction presenting with new right bundle branch block (RBBB), and therapeutic use of inhaled epoprostenol to reduce RV afterload and augment cardiac output during refractory cardiogenic shock. CASE REPORT A 53-year-old male presented to our institution in ventricular fibrillation with subsequent development of RBBB in the setting of proximal right coronary artery occlusion...

INTRODUCTION: Malignant hyperthermia (MH) is an inherited hypermetabolic condition characterized by uncontrolled calcium release from the sarcoplasmic reticulum of skeletal muscle, usually from exposure to inhaled general anesthetics and/or the depolarizing neuromuscular blocking agent succinylcholine. Multiple case reports now reveal that crises may be precipitated by environmental factors such as exercise or high ambient temperatures. Common signs of an MH crisis include life-threatening hyperthermia, metabolic acidosis, muscle rigidity, and tachycardia...

During a judicial inquiry, the forensic doctor is frequently required to examine the hospitalized fire victim. He has to produce a certificate on the burns, defining their origin, seriousness and prognosis. The expert assessment of serious burn victims consists in an overall evaluation of functional and psychological sequelae, and can be conducted only after the long period of treatment needed for them to heal. The expert must know the forensic rules concerning the specific features of sequelae that follow a cutaneous burn injury...

BACKGROUND: Respiratory diseases are mainly derived from acute and chronic inflammation of the alveoli and bronchi. The pathophysiological mechanisms of pulmonary inflammation mainly arise from oxidative damage that could ultimately lead to acute lung injury. Apigenin (Api) is a natural polyphenol with prominent antioxidant and anti-inflammatory properties in the lung. Inhalable formulations that consist of nanoparticles (NPs) have several advantages over other administration routes, and therefore, this study investigated the application of apigenin-loaded bovine serum albumin nanoparticles (BSA-Api-NPs) for pulmonary delivery...

The use of electronic cigarettes has become increasingly popular with claims suggesting healthier alternatives to tobacco cigarettes. However, research regarding the safety of such devices has been limited to an analysis of the inhaled vapor and the short and long-term effects on the body. A lesser recognized risk of electronic cigarette use is that of lithium-ion battery failure causing ignition, leading to severe thermal injury. Such incidents have been reported in the media but with inconsistencies from a lack of focus on the injuries sustained and a cause of ignition...

Postconditioning with inhalational anesthetics can reduce ischemia-reperfusion brain injury, although the cellular mechanisms for this effect have not been determined. The current study was designed to test if TASK channels contribute to their neuroprotective actions. Whole cell recordings were used to examine effects of volatile anesthetic on TASK currents in cortical neurons and to verify loss of anesthetic-activated TASK currents from TASK(-/-) mice. A transient middle cerebral artery occlusion (tMCAO) model was used to establish brain ischemia-reperfusion injury...

Minocycline has been demonstrated to exert neuroprotective effects in various experimental models. In the present study, we investigated the mechanisms underlying the protective effects of minocycline on cell injury induced by the inhalation of the anesthetic, sevoflurane. In our in vivo experiments using rats, minocycline attenuated sevoflurane-induced neuronal degeneration and apoptosis in the rat hippocampus, and this effect was associated with the minocycline-mediated suppression of oxidative stress in the hippocampus...
