| bronchiolitis obliterans organizing pneumonia and erythema nodosum are immunologic diseases that have not been reported to occur together. We report the case of a lady who developed bronchiolitis obliterans organizing pneumonia and erythema nodosum simultaneously, several weeks after smoke inhalation in a house fire. ( info) |
2/41. Pneumomediastinum associated with inhalation of white smoke. Hexachloroethane (HC) smoke, also known as white smoke, is an obscurant used in numerous military situations. Many adverse health effects are associated with the use of white smoke, some of which are potentially life threatening. inhalation is the most frequent route of injury. Two deaths among U.S. Army personnel resulted from HC smoke exposure in 1988. As recently as 1997, a united nations soldier in Bosnia died after an HC smoke canister was discharged in his tent. Injuries are predominantly pulmonary and range from cough and dyspnea to chemical pneumonitis, pulmonary edema, and adult respiratory distress syndrome. In the case presented, a soldier developed pneumomediastinum after exposure to HC smoke. This is the first case reported in the literature of pneumomediastinum associated with HC smoke inhalation.

3/41. zinc chloride smoke inhalation: a rare cause of severe acute respiratory distress syndrome. zinc chloride smoke inhalation is a rare cause of slowly progressive and often fatal acute respiratory distress syndrome (ARDS). The conventional treatment includes intravenous N-acetylcysteine, L-3, 4-dehydroproline, methylene blue, and respiratory support according to the lung protective strategy. This report presents the cases of three patients with serious zinc chloride inhalation and ARDS, the last of whom survived after prolonged intensive care, videothoracoscopic excision of emphysema bullae, and recurrent chemical pleurodesis.

| The objective of this study was to discuss the case of a patient with severe smoke inhalation-related respiratory failure treated with extracorporeal support. The study was set in a 12-bed multi-trauma intensive care unit at a level one trauma center and hyperbaric medicine center. The patient under investigation had carbon monoxide poisoning, and developed acute respiratory distress syndrome and cardiovascular collapse following smoke inhalation. Rapid initiation of extracorporeal support, extreme inverse-ratio ventilation and intermittent prone positioning therapy were carried out. Admission and serial carboxyhemoglobin levels, blood gases, and computerized tomography of the chest were obtained. The patient developed severe hypoxia and progressed to cardiovascular collapse resistant to resuscitation and vasoactive infusions. Veno-venous extracorporeal support was initiated. Cardiovascular parameters of blood pressure, cardiac output, and oxygen delivery were maximized; oxygenation and ventilation were supported via the extracorporeal circuit. Airway pressure release ventilation and intermittent prone positioning therapy were instituted. Following 7 days of extracorporeal support, the patient was decannulated and subsequently discharged to a transitional care facility,neurologically intact. smoke inhalation and carbon monoxide poisoning may lead to life-threatening hypoxemia associated with resultant cardiovascular instability. When oxygenation and ventilation cannot be achieved via maximal ventilatory management, extracorporeal support may prevent death if initiated rapidly. ( info) |
5/41. Acute pulmonary oedema following smoke inhalation. A case of acute pulmonary oedema after smoke inhalation from a chip pan fire is presented. The role of bronchial and pulmonary circulation in the development of pulmonary oedema after smoke inhalation is discussed. We stress the importance not only of observation after smoke inhalation, as the manifestation of pulmonary oedema may be delayed, but also of a baseline chest X-ray before admission for comparison.

6/41. Failure to clear casts and secretions following inhalation injury can be dangerous: report of a case. A 27-year-old man suffered smoke inhalation during a fire. Three days later, he complained of respiratory difficulty and was admitted to our hospital. bronchoscopy revealed a very large buildup of sputum mixed with soot extending from the left main bronchus to the bifurcation of the upper and lower lobe bronchi and causing both pulmonary atelectasis and pneumonia. The debris was successfully removed the next day with basket forceps via bronchoscopy. The patient's airway pressure dropped significantly, enabling extubation almost immediately. Because of the possibility for respiratory failure caused by viscous secretion, it is important to perform initial bronchoscopy in cases of suspected inhalation injury. ( info) |
7/41. Early and late fatal complications of inhalation injury. Severe inhalation injury causes a substantial deterioration in the prognosis and increases the general mortality of patients with extensive burns. Recently, in particular due to the development of invasive monitoring of patients and effective treatment of acute burn shock, we encounter with increasing frequency patients who survive the acute stage, including complications such as ARDS, and reach the stage of late complications. The latter include tracheooesophageal fistulas that develop on the basis of pressure ulcers and chondromalacia, usually at the site of the balloon of the tracheostomic cannula, and the overproduction of fibrous tissue in the area of the airways which leads to the development of stenosis, pulmonary fibrosis and bronchiectasia. Frequently, different early and late complications combine. ( info) |
8/41. Acute eosinophilic pneumonia in a new york city firefighter exposed to World Trade Center dust. We report a sentinel case of acute eosinophilic pneumonia in a firefighter exposed to high concentrations of World Trade Center dust during the rescue effort from September 11 to 24. The firefighter presented with a Pa(O2) of 53 mm Hg and responded to oxygen and corticosteroids. Computed tomography scan showed patchy ground glass density, thickened bronchial walls, and bilateral pleural effusions. bronchoalveolar lavage recovered 70% eosinophils, with only 1% eosinophils in peripheral blood. eosinophils were not degranulated and increased levels of interleukin-5 were measured in bronchoalveolar lavage and serum. Mineralogic analysis counted 305 commercial asbestos fibers/10(6) macrophages including those with high aspect ratios, and significant quantities of fly ash and degraded fibrous glass. Acute eosinophilic pneumonia is a rare consequence of acute high dust exposure. World Trade Center dust consists of large particle-size silicates, but fly ash and asbestos fibers may be found in bronchoalveolar lavage cells. ( info) |
9/41. Plastic reconstruction of an extended corrosive injury of the posterior tracheal wall with an autologous esophageal patch. We report on a patient with an extended corrosive injury of the posterior tracheal wall and left-sided tracheo-esophageal fistula after severe inhalative trauma. Resection of the fistula and necrotic tissue was followed by reconstruction of the posterior tracheal wall with an esophageal patch. Interposition of the stomach was performed to restore upper gastro-intestinal continuity. Revision was necessary due to an anastomotic insufficiency and a recurrent fistula between the trachea and the esophago-gastrostomy on the left side. The stomach was resected and the fistula was covered with a sternocleidomastoideus muscle flap. Several weeks later interposition of the right hemicolon was performed to establish the gastro-intestinal tract and the patient recovered completely, thereafter. ( info) |
| A previously healthy 26 year old woman who was exposed to smoke during a house fire developed acute anterior myocardial infarction complicated by ventricular fibrillation. Subsequent left ventriculography confirmed anterior infarction, but coronary arteriography was normal apart from myocardial bridging over a segment of the left anterior descending artery. The development of acute myocardial infarction in this patient suggests that, in the presence of bridging, carbon monoxide inhalation may cause regional infarction. ( info) |
