Two adults were admitted to the University Hospital of Geneva with acute Haemophilus influenzae type b epiglottitis. The disease was characterized by rapid progression of sore throat, upper dysphagia, fever and dyspnea. Acute upper airway obstruction required emergency tracheotomy in both cases. The patients recovered under ampicillin therapy. All the 100 cases from the literature for which clinical data were available have been analyzed:--Epiglottitis in adult is not exceptional.--Haemophilus influenzae type b is the most common infective organism documented, and was found in all positive blood cultures but one.--The typical presentation is severe sore throat, with upper dysphagia, fever and dyspnea.--Clinical course is rapid and serious, and acute respiratory distress develops in 57% of cases; overall mortality is 27%.--Emergency routine tracheotomy appears to be the most reliable treatment.

Report on two deaths from a natural internal cause in children beyond the first year of life. The children (a two-year and a three-year old boy), who seemed completely healthy, sudden suffered from acute inflammation of the upper respiratory tract with dyspnea, inspiratory stridor, fever, dysphagia, and flow of saliva. The disease took a fulminant course and the children died within a few hours showing symptoms of intense dyspnea and cyanosis. The above symptoms and progress were typical of acute epiglottitis. Autopsy revealed an intense inflammation and tumescence of the epiglottis in both cases. The diagnosis of epiglottitis was confirmed histologically and bacteriologically (Haemophilus influenzae).

Purulent bronchitis was identified in 19 of 422 patients undergoing fiberoptic bronchoscopy during a 32-month period because of suspicion of an opportunistic lung infection complicating acquired immunodeficiency syndrome or human immunodeficiency virus infection. Five patients had Pneumocystis carinii pneumonia, but other opportunistic lung infections were excluded in the remaining 14 patients. Characteristics of these 14 patients included fever (greater than 38.3 degrees C), cough, and dyspnea in 14 of 14 patients; purulence of expectorated sputum (11/14); and widened alveolar-arterial oxygen gradient (13/14). Rapid (2 +/- 1.4 days) clinical response (defervescence and resolution of pulmonary symptoms) occurred with antibiotic therapy in 10 of 14 patients. In three patients, there was no improvement, and adult respiratory distress syndrome developed. Bacterial isolates from bronchoalveolar lavage included Streptococcus viridans (n = 12), Haemophilus influenzae (n = 7), Staphylococcus aureus (n = 3). Roentgenographic features of bronchiectasis were present in seven patients. Differential cell counts revealed greater than 50% neutrophils in the bronchial washings of all patients with purulent bronchitis. Neutrophil percentages in bronchoalveolar lavage were as follows: patient with purulent bronchitis without P carinii pneumonia (n = 14), 54.53% +/- 29.18%; patients with purulent bronchitis and concomitant P carinii pneumonia (n = 5), 62% +/- 31.9%. In a control group of 17 patients with P carinii pneumonia who did not have purulent bronchitis, the neutrophil percentage was 6.8% +/- 6.17% (p = less than 0.00001, t-test). Purulent bronchitis appears to be a distinct, treatable entity in patients with HIV infection and may accompany bacterial pneumonia, bronchiectasis, and P carinii pneumonia.

Approximately 4% of recipients of solid organ transplants in the United States develop bacterial pneumonia in the posttransplant period, often in the first 3 months following transplantation. The incidence of bacterial pneumonia is highest in recipients of heartlung (22%) and liver transplants (17%), intermediate in recipients of heart transplants (5%), and lowest in renal transplant patients (1 to 2%). The crude mortality of bacterial pneumonia in solid organ transplantation has exceeded 40% in most series. Beyond those risk factors identified for nosocomial pneumonia, the occurrence of primary cytomegalovirus (CMV) infection, graft rejection, maintenance antirejection therapy with prednisone, azathioprine, and antilymphocyte globulin, antirejection therapy with high-dose corticosteroids or OKT3 and splenectomy have been associated with a significantly increased risk of bacterial pneumonia in these patients. In the first 3 months posttransplant, gram-negative bacilli, Staphylococcus aureus and Legionella predominate and mortality is very high, in excess of 60%. Thereafter, bacterial pneumonias are caused primarily by Streptococcus pneumoniae and Hemophilus influenzae, with considerably lower mortality. Bacterial pneumonia must be suspected in any transplant patient presenting with fever and cough, especially associated with dyspnea or infiltrates on chest radiograph. If large numbers of bacteria and polymorphonuclear leukocytes are not visualized in respiratory secretions the work-up should proceed directly to fiberoptic bronchoscopy with bronchoalveolar lavage and/or protected brush specimen to establish the microbiologic diagnosis as accurately as possible. For presumptive gram-negative bacillary pneumonia, the initial regimen must be effective against Pseudomonas aeruginosa. Prevention of bacterial pneumonia in transplant patients must begin with immunization against S pneumoniae and Influenza A, and include precautions taken to prevent nosocomial pneumonia. It further may include measures to prevent CMV infection and the use of trimethoprim/sulfamethoxazole prophylaxis during the first year posttransplantation. Ultimately, novel technologies such as selective antimicrobial decontamination and/or protective isolation during the early postoperative period may prove effective.

During the 11 month period up to 30 September 1987, 37 patients (26 male, 11 female, mean age 27 years) with respiratory symptoms who were human immunodeficiency virus (HIV) positive, were studied prospectively on 40 occasions to determine the cause of any pulmonary complications. HIV was heterosexually transmitted. Predominant symptoms were cough (89%), fever (89%), weight loss (83%), and dyspnoea (60%). Transnasal fibre-optic bronchoscopy (with bronchoalveolar lavage, bronchial brushings and transbronchial lung biopsies) was performed on 35 patients, twice on 3 patients. 'Tru-cut' lung biopsies were obtained from 2 patients who died before bronchoscopy. Pulmonary tuberculosis was the commonest disease, being found in one-third of the patients (12 of 37). Mycobacterium tuberculosis was cultured from 4; the remainder of the plates were contaminated. Pneumocystis carinii was present in 8 patients: as the sole pathogen in 3, with Streptococcus pneumoniae in 4, Staphylococcus aureus in 2, and one also had tuberculous lymphadenitis. Endobronchial Kaposi's sarcoma was seen in 6 of 7 patients with skin nodules. Bacterial pathogens isolated included Staph. aureus (5), S. pneumoniae (5), Klebsiella pneumoniae (2), Haemophilus influenzae (2), H. parainfluenzae (1) and Pseudomonas aeruginosa (1). Invading Aspergillus fumigatus was diagnosed by lung biopsy in one. No diagnosis was reached for 8 patients. It is concluded that in Central Africa pulmonary complications in AIDS patients are similar to those in Europe and North America but the incidence of different pathogens depends on the prevalence of pathogens in the community. M. tuberculosis is probably the commonest pathogen. This study has confirmed that P. carinii pneumonia does occur, but occurs less frequently.

Laryngoscopic examination of new-born infants with laryngeal dyspnea or dysphonia usually reveals a congenital lesion, but true infections laryngitis, although rare, does still exist. Three cases are reviewed and the literature searched. Functional laryngeal signs are non-pathognomonic, all three levels of the larynx may be affected by inflammation, and pathogenic agents may be viral (herpes), bacterial (Haemophilus Para-Influenzae) or mycotic. In two of the cases reported confirmation of diagnosis was by local swab under laryngoscopic guidance. Recovery occurred after medical treatment alone and intubation was not required in any of the three patients. These findings emphasize the value of laryngoscopy with swab in all neonates with dyspnea or dysphonia in an infectious context.

Chronic obstructive pulmonary disease (COPD) is equated with chronic bronchitis and emphysema as one disease entity. In COPD airflow limitation is relatively persistent--unlike asthma. Tests for "small-airways disease" form no part of routine practice, for their accuracy in detecting pathological change is debatable. The proteolytic theory of the pathogenesis of emphysema highlights the role of neutrophil elastase, antielastases, oxidants, antioxidants, and thus of potential new treatments. Clinical features of COPD include breathlessness, cough, and sputum, with airflow obstruction and lung hyperinflation. The differential diagnosis includes bronchiectasis, cystic fibrosis, and pulmonary hypertension, but pulmonary fibrosis, etc., is distinguished by radiological infiltrates. Plain chest radiography cannot reliably diagnose emphysema in life, but a new method measuring lung density from the computed tomographic (CT) scan allows location, quantitation, and diagnosis of emphysema (defined by enlargement of distal air spaces) in humans in life. "Pink puffers" with breathlessness, hyperinflation, mild hypoxemia, and a low PCO2 are contrasted with "blue bloaters" with hypoxemia, secondary polycythemia, CO2 retention, and pulmonary hypertension and cor pulmonale. Antismoking measures are a major aim in management. A bronchodilator regimen combining a slow-release oral theophylline with an inhaled beta 2-agonist, ipratropium, and high-dose inhaled steroids is proposed because even modest improvement in obstruction can help these patients. In acute exacerbations with purulent sputum, antimicrobials against Streptococcus pneumoniae and Hemophilus influenzae are used with controlled oxygen therapy aiming to keep the arterial PO2 over 50 mm Hg without the pH falling below 7.25. Influenza prophylaxis is recommended, but pneumococcal vaccination remains debatable. Chronic under-nutrition in "emphysema" implies controlled trials of feeding regimens--but these remain to be assessed. Long-term oxygen therapy is the only treatment known to prolong life in blue bloaters, and oxygen concentrators and transtracheal oxygen delivery are discussed. Pulmonary vasodilators (e.g., beta 2-agonists, hydralazine, nifedipine, angiotensin-converting enzyme [ACE] inhibitors, etc.) have not yet been proved to provide long-term reduction in pulmonary arterial pressure. Blue bloaters have severe nocturnal hypoxemia in rapid eye movement (REM) sleep that is corrected by oxygen or the investigational drug almitrine.(ABSTRACT TRUNCATED AT 400 WORDS)

Three patients had diffuse reticulonodular shadowing on chest roentgenogram, dyspnea, cough, purulent sputum, airways obstruction, variable fever, and leukocytosis. Lung tissue from two showed inflammatory exudate in bronchioles and peribronchiolar alveoli; all had multiple isolates of either Haemophilus influenzae or Streptococcus pneumoniae from sputum or lung tissue. When examined in the context of similar syndromes reported by others under different labels in the past, these observations suggest that this is a specific clinical entity, which is both uncommon and serious. Despite initial misdiagnosis in all three cases, the two patients in whom the true nature of the disease was promptly recognized had complete recovery after the institution of appropriate antibacterial therapy. The most accurate and appropriate term for this entity is diffuse bacterial bronchiolitis with bronchiolar pneumonia.

Haemophilus influenzae and Streptococcus pneumoniae are found in 87% of all cases of exacerbated chronic obstructive bronchopulmonary disease. Complications of viral respiratory tract disease are most frequently caused by H. influenzae. Not only encapsulated forms of H. influenzae, but also non-encapsulated strains may be responsible for the onset of pneumonia and acute exacerbations of chronic bronchitis in adults. The most common symptoms of infections with H. influenzae are cough, dyspnoea, increase in purulent sputum and wheezing. A quantitative sputum culture is recommended for diagnosing chronic obstructive bronchopulmonary disease. Acute exacerbations of chronic bronchitis are always treated with antibiotics effective against H. influenzae and pneumococci. As a rule, empirical treatment should suffice in general practice. In the comparison between ampicillin, co-trimoxazole and cefaclor included in the study protocol appended to this report, the latter produced the most favourable results both in the empirical and specific forms of treatment. We would recommend cefaclor as the antibiotic of choice for this disease.

Imipenem, a potent new beta-lactam antibiotic, which is bactericidal against most pathogenic bacteria, and cilastatin, a dehydropeptidase inhibitor combined with imipenem to prevent the metabolism of imipenem in the kidney, were evaluated in the treatment of bacterial endocarditis. Seventeen patients, including 14 who used intravenous drugs, were treated with imipenem/cilastatin in a dose of 500 mg each infused over 30 minutes every six hours. The mean duration of treatment was 29 days with a range of 21 to 56 days. Causative bacteria were Staphylococcus aureus in 10 patients, S. aureus plus group B Streptococcus in one, viridans group Streptococcus in two, Neisseria subflava, Eikenella corrodens, and group G Streptococcus in one patient, and Staphylococcus epidermidis, Hemophilus aphrophilus, and Enterobacter aerogenes in one patient each. The minimal bactericidal concentration of imipenem against 16 of 18 isolates tested was 0.04 micrograms/ml, 1 microgram/ml against H. aphrophilus, and 0.4 micrograms/ml against E. aerogenes. The site of infection was the right side of the heart in 11 patients, the left side in five, and both sides in one. The mean number of days to defervescence was 9.7. All patients were cured, and none required cardiac surgery. Adverse effects were few and interrupted treatment occurred in only one patient who had acute dyspnea during an infusion on Day 26 of therapy. Imipenem/cilastatin appears to be a relatively safe and highly effective treatment of staphylococcal endocarditis in intravenous drug users; too few patients with endocarditis caused by other bacteria were treated to allow a firm statement about efficacy in non-staphylococcal endocarditis.
