Eleven cases of blood culture-positive, community-acquired pneumonia due to the human commensal Acinetobacter baumannii were studied in Darwin in the Northern Territory of Australia during the 10-year period from March 1981 through February 1991. Demographic risk factors included male gender, age of greater than 45 years, and Aboriginal ethnic background. Multiple clinical risk factors, including cigarette smoking, alcoholism, chronic obstructive airway disease, and diabetes mellitus, were noted in all cases and contributed to the high mortality (64%). In all cases pneumonia was clinically fulminant. A fatal outcome was strongly associated with inappropriate initial antibiotic therapy. All tested isolates of Acinetobacter were sensitive to gentamicin and resistant to cefotaxime. The 34 previously reported cases of community-acquired acinetobacter pneumonia are reviewed, and appropriate therapeutic regimens are identified.

Initially a right sided pulmonary hypoplasia was diagnosed in our patient at the age of 9 years. The previous years were characterized by recurrent pneumonia, bronchitis and daily coughing fits. Findings of the chest radiograph suggested the diagnosis of right sided hypoplasia. The right hemithorax was small with mediastinal structures being pushed to the right and a clearly reduced blood flow on the same side. DSA of the arteria pulmonalis showed hypoplasia of the right arteria pulmonalis and confirmed our diagnosis. In addition to that an obstructive airway disease was assessed by measurement of lung function. Since the time when the diagnosis was found our patient has inhaled DSCG and beta 2-adrenergic drugs and no surgical treatment has been required as there have been no further episodes of pneumonia.

Kr-81m ventilation and Tc-99m perfusion images of 392 patients were examined retrospectively for the incidence and etiology of the reverse mismatch defect, which is characterized by a region of lung where the perfusion defect exceeds the ventilation defect. Forty-six patients (11.7%) showed such defects. The most frequent causes were pneumonia (15%), atelactasis (15%), pleural effusions (15%), chronic obstructive airway disease (24%), and bronchial obstruction (31%). The significance of the reverse mismatch defect is discussed.

Fifty-eight patients were ventilated for acute respiratory failure complicating respiratory diseases between 1985 to 1990. There were 19 cases of chronic obstructive airway disease (COAD), 17 cases of asthma, 16 cases of pneumonia and 6 cases with other diagnoses. Overall, 40% of patients survived and were discharged from the ward. Patients with pneumonia had the lowest survival rate (25%) whilst the survival rates for asthma and COAD were 47% and 42% respectively. Increasing age had an inverse relationship to survival rate (r = 0.96, p < 0.05) but the duration of ventilation did not correlate with survival. Patients who were electively ventilated before respiratory arrest had a better chance of survival (57%) compared with only 18% survival rate in patients who were ventilated as an emergency (x2 = 4.47, p < 0.05). Patients who developed other organ failure had higher mortality (71%) than those who did not (22%; x2 = 2.14, p < 0.05). We conclude that patients younger than 50 years of age, who were electively ventilated and without other organ failure had a better immediate survival after assisted ventilation.

Twenty-nine patients (16 males, 13 females) with spontaneous pneumothorax admitted into Hospital Universiti Sains Malaysia, Kubang Kerian, from September 1984 to September 1990 were reviewed. Their ages ranged from newborn to 75 years. The commonest chief presenting symptom was dyspnoea (69%), followed by chest pain (35%). Four patients had chronic obstructive airway disease, 7 had pneumonia, 2 had pulmonary tuberculosis, one patient had emphysema while 4 patients had multiple underlying lung disorders. The left and right lungs were involved with equal frequency. Bilateral pneumothorax occurred in one patient. Most patients had a single episode of pneumothorax but recurrent pneumothoraces occurred in 3 patients (10%). Six patients were observed conservatively, 20 patients required chest tube insertion alone and 3 patients also required pleurodesis. Death occurred in 8 patients (28%) mainly due to coexisting infection and respiratory failure.

To assess awareness and understanding of obstructive airway diseases by primary-care physicians, the authors surveyed a randomly selected population of 75 primary care practitioners. During one-on-one interviews, physicians were presented with a standardized case scenario and a subsequent series of open-ended questions concerning asthma and COPD. Each respondent was presented in randomized fashion with one of two versions of a case description of a hypothetical 52-year-old male smoker with a recent upper respiratory tract infection and persistent productive cough. The only difference between case descriptions was that one included explicit reference to an earlier tentative diagnosis of chronic bronchitis (CB version); the other description made no specific mention of this diagnostic term (NCB version). Chest radiographs were requested by 80 percent of physicians and sputum cultures by 50 percent, these percentages not differing significantly between CB and NCB groups. Spirometry was requested less often than either of the foregoing tests (21 percent). The CB group requested spirometry significantly more often than the NCB group (38 percent vs 5 percent, p < 0.05). The most frequently mentioned primary diagnosis was bronchitis/pneumonia (33 percent), followed by bronchitis (28 percent) and chronic bronchitis (16 percent), all of which were similar in both groups. However, the diagnostic term "COPD" was the primary diagnosis in 16 percent of the CB group, compared with 8 percent in the NCB group (p > 0.05). Oral antibiotics were the most frequently chosen first-line drug therapy (63 percent). In subsequent questions concerning the management of obstructive airway diseases, primary practitioners distinguished COPD from asthma conceptually, but their prescribed therapy for the two disorders was less distinct. beta 2-agonists were selected most frequently and similarly as initial therapy for both disorders (53 percent). Minor differences between first-line therapeutic choices included nonsignificant trends toward the more frequent mention of anticholinergic bronchodilators for COPD than for asthma (10 percent vs 0 percent) and the more frequent selection of inhaled corticosteroids for asthma (12 percent vs 5 percent). The authors conclude that to the extent that questionnaire responses reflect actual practice, primary care practitioners (1) have a low index of suspicion for obstructive airway disease, (2) markedly underutilized spirometry as a screening tool, (3) consider beta 2-agonists first-line therapy for COPD and asthma, and (4) despite considering COPD and asthma different disease processes, choose similar medications for each disorder.

1. After ingestion, Dettol liquid (4.8% chloroxylenol, pine oil, isopropyl, alcohol), a common household disinfectant, can cause central nervous system depression and corrosion of the oral mucosa, larynx and the gastrointestinal tract. The main risk from Dettol poisoning is pulmonary aspiration, leading to pneumonia, adult respiratory distress syndrome (ARDS) and/or sudden cardiorespiratory arrest. 2. To determine to what extent pulmonary aspiration in Dettol poisoning could be prevented, 13 patients treated in a general teaching hospital in Hong Kong were studied. Their clinical details were compared with those of control Dettol poisoning cases without pulmonary aspiration in order to identify possible risk factors for this complication. 3. At presentation, evidence of pulmonary aspiration was present in eight of the 13 patients prior to gastric emptying, but the use of gastric lavage without adequate protection of the airways could have aggravated the problem in three. In two other patients, evidence of aspiration was only present after gastric lavage was performed. The consequences of pulmonary aspiration were pneumonia (n = 10), ARDS (n = 2), acute exacerbation of asthma or chronic obstructive airway disease (n = 2) and sudden cardiorespiratory arrest (n = 1). Three patients with aspiration pneumonia (n = 2), ARDS (n = 1) and/or sudden cardiorespiratory arrest (n = 1) died. 4. Compared with the controls, the median amount of Dettol ingested was considerably larger (400 vs 150 ml), vomiting (100% vs 72.6%) and drowsiness/ confusion (60.2% vs 19.4%) occurred more often. 5. Amongst the 13 patients with Dettol poisoning and pulmonary aspiration, gastric lavage using the nasogastric tube technique without adequate production of the airways had been responsible for the occurrence or worsening of aspiration in two and three patients, respectively. Thus, gastric lavage particularly when using a nasogastric tube appeared to carry more harm than benefits in patients with Dettol poisoning. If the procedure is considered necessary, say because of the concomitant ingestion of the other poisons, the airways must first be well protected and the oropharyngeal aspiration and lavage technique using a wide bore Jacques tube is recommended. 6. Comparison with a control group has identified other risk factors for pulmonary aspiration: the amount of Dettol ingested, the occurrence of vomiting, drowsiness or confusion.

To determine changes in hospital mortality that occurred in association with the dissemination of data by a regional initiative to profile hospital performance, we conducted a retrospective cohort study of patients admitted before and subsequent to dissemination of comparative data in 1992. The analysis included 101,060 consecutive eligible discharges from 30 hospitals in Northeast Ohio with eight diagnoses: acute myocardial infarction, congestive heart failure (CHF), obstructive airway disease, gastrointestinal hemorrhage, pneumonia, stroke, coronary artery bypass surgery, and lower bowel resection. Baseline (1991, N = 35,629) mortality rates were compared to rates during three subsequent periods (July-December 1992, N = 20,392; January-June 1993, N = 23,070; and July-December 1993, N = 21,969). Mortality rates were risk-adjusted using validated multivariable models based on data abstracted from patient's medical records. For all conditions, risk-adjusted mortality declined from a baseline rate of 7.5% to rates of 6.8%, 6.8%, and 6.5%, respectively, during the three subsequent periods. Using weighted linear regression analysis to estimate trends across periods, declines in mortality rates were significant for CHF (0.50% per period; P = 0.002) and pneumonia (0.38% per period; P = 0.03). We conclude that hospital mortality declined in association with the dissemination of comparative data. Although changes in hospital care were not directly examined, the results suggest that initiatives to examine provider performance may have a beneficial impact on quality of care.

Many countries' guidelines recommend pneumococcal vaccination for patients suffering from obstructive airway disease. This paper reviews the literature as to immunogenicity and safety of this immunization. There is no evidence for a negative effect of pneumococcal vaccination on these patients. Only a few data exist on the preventive impact of pneumococcal vaccination as to exacerbations of obstructive airway diseases. Existing studies mostly took up this question as a side aspect. The effect in children and adults appears limited. On the other hand, the pneumococcal conjugate vaccine prevents life-threatening invasive infections in children younger than 5 years, and pneumococcal polysaccharide vaccine protects healthy adults against bacteriaemic pneumonia. Thus, pneumococcal vaccination of patients suffering from obstructive airway disease is recommendable.

We report a case of bacterial pericarditis in an immunologically competent adult female caused by nonencapsulated Haemophilus influenzae (H influenzae) that was complicated by the acute development of life-threatening pericardial tamponade. H influenzae is a gram-negative coccobacillus, a pathogen most frequently associated with childhood exanthema (otitis media, meningitis) and, less frequently, adult pneumonia. Encapsulated, type b, or typable H influenzae is the strain implicated in childhood infections. On the other hand, nonencapsulated or nontypable H influenzae is the specific strain most often associated with exacerbation of chronic obstructive airway disease. Bacterial pericarditis caused by either subtype of H influenzae is exceedingly rare. We have located only 15 previously reported cases of H influenzae pericarditis occurring in adults in the world medical literature, the majority of which date back to the pre-antibiotic era. In 12 of these 15 cases (the only cases in which typing could be accomplished), the encapsulated strain of H influenzae was cultured from the pericardial fluid. Thus, to the best of our knowledge, we are reporting here the first case of bacterial pericarditis caused by nonencapsulated H influenzae in an immunologically competent adult.
