Prophylaxis of alcohol withdrawal syndrome (AWS) in alcohol-dependent patients shortens the duration of stay in the intensive care unit (ICU). The objective of this study was to assess the effect of four different prophylactic regimens on the duration of ICU stay, prevention of AWS and rate of major intercurrent complications in alcohol-dependent patients admitted to the ICU after tumour resection. A total of 197 alcohol-dependent patients, diagnosed by the Diagnostic and Statistical Manual of Mental Disorders (third revised edition) with a daily ethanol intake of 60 g, were allocated randomly to one of the following regimens which were commenced on admission to the ICU: flunitrazepam-clonidine, chlormethiazole-haloperidol, flunitrazepam-haloperidol or ethanol. The duration of ICU stay, prevention of AWS, incidence of tracheobronchitis and major intercurrent complications such as pneumonia, sepsis, cardiac disorders, bleeding disorders and death were documented. On admission, patients did not differ significantly in age, APACHE II and multiple organ failure scores. ICU stay, incidence of AWS, severity of AWS (revised clinical institute withdrawal assessment for alcohol scale > 20) and major intercurrent complication rate did not differ significantly between groups. Although there was no advantage in any of the four regimens with respect to the primary outcome measures, pulmonary and cardiac patients were not included in the study. Patients in the chlormethiazole-haloperidol group had a significantly increased incidence of tracheobronchitis (P = 0.0023), probably because of an increased incidence of hypersecretion.

Aspergillus can cause a wide spectrum of pulmonary complications. It may colonize pre-existing cavities to form mycetomas. In asthmatic patients it may lead to a hypersensitivity reaction involving eosinophilic infiltration of the bronchial wall and mucoid impaction (a condition called allergic bronchopulmonary aspergillosis) or granulomatous inflammation (bronchocentric granulomatosis). In the immunocompromised host, Aspergillus may invade blood vessels, causing hemorrhagic infarction (angioinvasive aspergillosis), or it may cause tracheobronchitis, bronchiolitis or pneumonia (airway invasive aspergillosis), as well as abscess formation with or without adjacent tissue invasion. Each of the manifestations of Aspergillus infection has a distinct histologic and high-resolution computed tomography (CT) appearance. This pictorial essay reviews the characteristic high-resolution CT and corresponding pathologic findings of pulmonary complications due to Aspergillus fumigatus.

From March 1995 to March 1997, sulbactam was prospectively evaluated in patients with non-life-threatening multiresistant Acinetobacter baumannii infections. During this period, 47 patients were treated with sulbactam; of them, five were excluded because they had received < or =48 h of sulbactam therapy. A total of 42 patients, 27 males and 15 females with a mean age of 60+/-15 years, were finally evaluated. Infections were as follows: surgical wound, 19; tracheobronchitis, 12; urinary tract, 7; catheter-related bacteraemia, 2; and pneumonia, 2. Eighteen patients received intravenous sulbactam alone (1 g every 8 h) and 24 patients received intravenous sulbactam/ampicillin (1 g:2 g every 8 h) with no major adverse effects. Of the 42 patients, 39 improved or were cured and showed A. baumannii eradication and one patient had persistence of wound infection after 8 days of sulbactam/ampicillin requiring surgical debridement. Two patients died after 3 days of therapy (one of the deaths was attributable to A. baumannii infection). The in-vitro activity of the sulbactam/ampicillin combination was by virtue of the antimicrobial activity exhibited by sulbactam. Killing curves showed that sulbactam was bacteriostatic; no synergy was observed between ampicillin and sulbactam. Our results indicate that sulbactam may prove effective for non-life-threatening A. baumannii infections. Its role in the treatment of severe infections is unknown. However, the current formulation of sulbactam alone may allow its use at higher doses and provide new potential synergic combinations, particularly for those infections by A. baumannii resistant to imipenem.

Although antimicrobial therapy has been administered through the inhaled route for decades, it has always been controversial. There are relatively few accepted indications for this mode of administration. Well-controlled studies of aerosolized antibiotics in cystic fibrosis demonstrate that tobramycin on a cyclical basis may reduce sputum volume, bacterial counts, and improve pulmonary function. Preliminary data indicate that inhaled antibiotic therapy of ventilator-associated tracheobronchitis may reduce sputum volume, but the clinical significance of this finding remains to be determined. Inhaled pentamidine is used for prophylaxis of Pneumocystis carinii in patients with human immunodeficiency virus infection who are intolerant of oral prophylactic agents. Ribavirin has been used for 30 years to treat respiratory syncytial virus. The role, if any, of inhaled antifungal therapy with amphotericin B remains undetermined.

We report the case of a young woman with Crohn's disease of the bowel who presented with a purulent tracheobronchitis and life-threatening upper airway obstruction. Fibreoptic bronchoscopy demonstrated severe tracheal and upper bronchial pseudotumours and stenosis. The role of recent discontinuation of corticosteroids, for quiescent inflammatory bowel disease, in the development of endobronchial disease and the dramatic response in airway patency after reintroduction of prednisolone in this rare complication of Crohn's disease are discussed.

We report 2 patients with necrotizing tracheobronchitis (NTB) associated with patent ductus arteriosus-dependent cyanotic congenital heart disease. The pathologic findings suggest that hypotension and decreased tracheo-bronchial perfusion were the major contributing factors in the development of NTB. Necrotizing tracheobronchitis developed in infants with pulmonary atresia and Ebstein's anomaly with pulmonary stenosis. Both infants required prostaglandin E1 infusion from early infancy, and presented with sudden onset of dyspnea and hypercapnea. In one infant, NTB developed prior to mechanical ventilation. In the other infant, NTB developed after 4 days of mechanical ventilation. Care of both infants involved minimal pressures and FiO(2), adequate humidification, and optimal temperature of inspired gases; these factors probably did not play a role in the development or worsening of NTB. Both infants had hypotension and hypoxemia. These factors could have contributed to the development of NTB because of decreased perfusion pressure and tissue hypoxia. As the area of necrosis and its severity correlated with the area of blood supply served by the specific feeding arteries, we speculate that tissue hypoperfusion was the major cause of NTB.

The aim of this study was to determine the incidence, the organisms responsible for and the impact on outcome of nosocomial tracheobronchitis (NTB) in the intensive care unit (ICU). This prospective observational cohort study was conducted in a 30-bed medical/surgical ICU over a period of 6.5 yrs. All patients ventilated for >48 h were eligible. Patients with nosocomial pneumonia (NP) without prior NTB were excluded. Patients with first episodes of NTB were compared with those without NTB by univariate analysis. The study diagnosed 201 (10.6%) cases of NTB. Pseudomonas aeruginosa was the most common bacteria. NP rates were similar in patients with NTB compared with patients without NTB. Even in the absence of subsequent NP, NTB was associated with a significantly higher length of ICU stay and duration of mechanical ventilation in both surgical and medical populations. Mortality rates were similar in NTB patients without subsequent NP compared with patients without NTB. Antimicrobial treatment in NTB patients was associated with a trend to a better outcome. Nosocomial tracheobronchitis is common in mechanically ventilated intensive care unit patients. In this population, nosocomial tracheobronchitis was associated with longer durations of intensive care unit stay and mechanical ventilation. Further studies are needed to determine the impact of antibiotics on outcomes of patients with nosocomial tracheobronchitis.

Mycoplasmas cause chronic inflammation and are implicated in asthma. Mast cells defend against mycoplasma infection and worsen allergic inflammation, which is mediated partly by histamine. To address the hypothesis that mycoplasma provokes histamine release, we exposed mice to Mycoplasma pulmonis, comparing responses in wild-type and mast cell-deficient KitW-sh/KitW-sh (W-sh) mice. Low histamine levels in uninfected W-sh mice confirmed the conventional wisdom that mast cells are principal sources of airway and serum histamine. Although mycoplasma did not release histamine acutely in wild-type airways, levels rose up to 50-fold above baseline 1 week after infection in mice heavily burdened with neutrophils. Surprisingly, histamine levels also rose profoundly in infected W-sh lungs, increasing in parallel with neutrophils and declining with neutrophil depletion. Furthermore, neutrophils from infected airway were highly enriched in histamine compared with naive neutrophils. In vitro, mycoplasma directly stimulated histamine production by naive neutrophils and strongly upregulated mRNA encoding histidine decarboxylase, the rate-limiting enzyme in histamine synthesis. In vivo, treatment with antihistamines pyrilamine or cimetidine decreased lung weight and severity of pneumonia and tracheobronchitis in infected W-sh mice. These findings suggest that neutrophils, provoked by mycoplasma, greatly expand their capacity to synthesize histamine, thereby contributing to lung and airway inflammation.

We describe a 44 year-old woman who presented with dyspnea and cough 5 years after initial diagnosis of ulcerative colitis. The evaluation of patient showed findings of large airway inflammation with tracheal wall thickening and mucosal irregularities. The etiology was investigated and was diagnosed as tracheobronchitis that is a rare extraintestinal manifestation of ulcerative colitis. She was treated with systemic corticosteroids and rapid clinical improvement was detected.
