Six auto parts manufacturing workers were referred for evaluation of a 6-week history of work-related dyspnea, cough, and fatigue. Two workers also reported fever and weight loss. All six worked in a machining area where a waterbased metalworking fluid was used and recirculated under high pressure, thereby creating an aerosol. Chest radiographs revealed pulmonary interstitial infiltrates in four workers. Lung function tests showed that four workers had decreased diffusing capacity. After removal from the work area, all workers recovered. The metalworking fluid was cultured for bacteria and fungi. Isolates from broth cultures were sonicated to obtain antigen extracts. Serum precipitins to one or more of the microbial isolates were identified in all six workers but not in eight of nine nonexposed control subjects. The most frequent precipitin response (six of six workers) was against antigens of Pseudomonas fluorescens, which was cultured from the metalworking fluid. In all workers, precipitins to at least one other cultured organism were detected; these included Aspergillus niger, Staphylococcus capitas, an acid-fast Rhodococcus sp, and Bacillus pumilus. This represents the first report of hypersensitivity pneumonitis associated with industrial exposure to aerosolized metalworking fluid. Observed precipitin responses to a variety of microbial contaminants in metalworking fluid strongly suggest a causative role for microbial antigens in the induction and elicitation of this manifestation of hypersensitivity pneumonitis.

This article gives a clinical analysis upon 60 cases of nosocomial acquired pneumonia. All the patients are > 18 years old and the onset time ranged from 3 to 180 days after they were hospitalized with an average of 38.77 days, mostly 30 days after admission (27 cases, 49%). Among the primary diseases, the hematologic disorder (18 cases, 30%) rank the first, followed by cerebrovascular disease (9 cases, 15%) and connective tissue disease (8 cases, 13.3%), The common inducing factors are the using of corticosteroids and chemotherapy (34 cases, 58%), tracheotomy and tracheal cannula (7 cases, 11.6%). Fever occurs in 96% of the patients and cough 63.3%. The positive rate of sputum bacterial culture is 95.46%. Pseudomonas aeruginosa isolated in 25 cases (56.8%). and Klebsiella pneumoniae 18 cases (40%). P. aeruginosa shows resistant to the third generation of cefalosporins more than before, and is sensitive to ciprofloxacin and polymyxin B, while K. pneumoniae is resistant to many kinds of antibiotics, especially ampicilline and carbenicilline. The death rate of infection of P. aeruginosa is 58.33% (14/25) and that of K. pneumoniae is 60% (12/18), that of mixed infection is 66.67% (16/23).

We prospectively studied 110 adult patients coming to Black Lion Hospital between August 1987 and July 1989 with community acquired pneumonia (CAP) for various etiologic agents and clinical and radiographic presentation. Streptococcus pneumoniae was the most common offending pathogen in 72% and 67.5% from sputum and lung aspirate (LA) Gram stain respectively, and in 41% by pneumococcal serotyping of sputum. Blood and LA culture grew Streptococcus pneumoniae in 4 (6%), Staphylococcus aureus in 4 (6%), Enterobacteriaceae in (3%), Pseudomonas, Klebsiella and Streptococcus viridans in one case each. Non-bacterial pathogens included Mycoplasma pneumoniae in 3 (3%), Influenza A in 4 (4%), Influenza B in 3 (3%) and psittacosis/LGV in 4 (4%). Fever, cough, chest pain, tachypnea and coarse crepitations/bronchial breathing were the most common presenting signs and symptoms. Thirty per cent had associated diarrhoea and vomiting initially and 9% had altered state of consciousness at admission. Six patients came in a state of shock. Thirty-nine per cent had underlying illnesses. Ninety-three per cent had either segmental or lobar consolidation. Parapneumonic effusion occurred in 14%. The mortality was 11%. Tachypnea, the presence of underlying illness, altered state of consciousness, extreme leucocytosis and the presence of bilateral and multilobar lung involvement were found to be signs of poor prognosis. Our finding is similar to those from other African countries, except that we are reporting psittacosis/LGV for the first time in Africa.

Hydrocarbon pneumonitis is usually related to accidental poisoning in children. We describe a case of hydrocarbon pneumonitis after petroleum aspiration in an adult fire eater. The main symptoms were cough, dyspnea, chest pain and fever. The patient showed bilateral infiltrates in the middle and lower parts of the lung, hypoxemia and a restrictive ventilatory defect. The evolution was complicated by superinfection with Pseudomonas aeruginosa and by pneumatoceles. The acute stage lasted three weeks, and the patient recovered without sequelae within two months. Prophylactic application of antibiotics and corticosteroids cannot be recommended for prevention of hydrocarbon pneumonitis.

A 38-year-old man, HIV-positive for 6 years, developed fever and cough with deterioration in his general state. Chest radiography demonstrated an infiltration in the left upper lobe and computed tomography showed a septated cavity. Three bronchioalveolar lavages over 4 weeks recovered Klebsiella, Candida, Pseudomonas and Staphylococcus in the lavage fluid. Acid-fast rods were not found in any of the microscopic preparations. His clinical condition and the radiological findings deteriorated despite appropriate antibiotic administration. A further cavity occurred in the right upper lobe and the inflammatory infiltrations extended further. Although no acid-fast organism had been demonstrated, tuberculostatic treatment was begun (daily 300 mg isoniazid, 600 mg rifampicin, 900 mg streptomycin, 2 g pyrazinamide). His general condition and the radiological findings rapidly improved. Four weeks after culturing the lavage fluid atypical Mycobacterium xenopi was isolated. This case illustrates the difficulty of diagnosing an atypical mycobacterial infection. It takes time and effort, but it is of great importance because up to 50% of patients with AIDS contract such infection. Early and appropriate treatment will significantly improve quality of life and life expectancy.

Fifty seven children with thoracic empyema (37 boys and 20 girls) aged less than 12 years were seen at the University of Port Harcourt Teaching Hospital between January 1989 and December 1991. Staphylococcus aureus was the most common organism isolated from the pus of these patients (36 (63%) patients). Pseudomonas aeruginosa, the next most common organism, was isolated in 10 (18%) patients. The most common symptoms at presentation were acute illness with fever and cough (51 (89%) patients). All the patients were treated with closed intercostal tube drainage and appropriate antibiotics. Decortication was resorted to in only one patient. There were two deaths and the overall survival rate was 97%.

In 31 adult patients with cystic fibrosis (CF) who were chronically infected with Pseudomonas aeruginosa we examined the effect of giving regular three monthly oral ciprofloxacin. Patients received ciprofloxacin or placebo for 10 days every 3 months for 1 yr in a randomized, double-blind, placebo-controlled study. During each course of treatment patients receiving ciprofloxacin reported an improvement in cough, sputum production and peak expiratory flow (PEF) P = < 0.005. During the year of study patients receiving ciprofloxacin showed an improvement in PEF when compared with those receiving placebo (P = < 0.05) but the changes in FEV1 and FVC were not statistically different in either group. Regular oral ciprofloxacin was well tolerated but did not prevent hospital admissions or reduce the number of courses of intravenous antibiotics throughout the year. The median MIC to ciprofloxacin in the active treatment group rose from 0.5 mg l-1 to 0.75 mg l-1 during treatment. We conclude that CF patients are likely to benefit from oral ciprofloxacin for exacerbations of respiratory symptoms. However, regular treatment with ciprofloxacin over 1 yr improves PEF but does not reduce the rate of hospital admissions with acute exacerbations of respiratory symptoms.

We identified 31 patients with human immunodeficiency virus (HIV) infection and lung abscess. All patients had advanced HIV disease, and the mean CD4 cell count was 17/mm3 (range, 2-50/mm3). Twenty-two patients (71%) had previous opportunistic infections, and 24 (77%) had previous pulmonary infections. Symptoms at the time of presentation included fever (90% of patients), cough (87%), dyspnea (35%), pleuritic chest pain (26%), and hemoptysis (10%). The microbiological etiology was established for 28 patients, and the pathogens recovered were bacteria (65%), Pneumocystis carinii (6%), fungi (3%), and mixed microorganisms (16%). The pathogens included Pseudomonas aeruginosa (11), Streptococcus pneumoniae (6), P. carinii (5), Klebsiella pneumoniae (5), Staphylococcus aureus (4), Aspergillus species (3), viridans streptococcus (2), Haemophilus influenzae (1), Streptococcus milleri (1), Proteus mirabilis (1), and Cryptococcus neoformans (1). Mycobacterium tuberculosis was not isolated; two patients for whom a microbiological etiology was not established responded to antituberculous therapy. Patients were treated for 2-12 weeks; 25% of the patients received > 4 weeks of therapy. The outcome was poor: 36% of the patients had recurrences, and 19% died. In patients with AIDS, lung abscess is associated with advanced HIV infection, is due to a broad spectrum of pathogens, responds poorly to antibiotics, and has a poor prognosis.

Underlying diseases, complications, clinical findings, and laboratory findings were evaluated in 158 cases of septicaemia admitted to Jikei University Hospital from 1975 to 1994, in order to conjectured factors that prescribe for the prognosis. 50% of the patients had underlying diseases. Malignancy including leukaemia (31 cases, 39.2%) was the most common underlying disease, followed by low birth weight infant (17 cases, 21.5%), aplastic anemia (9 case, 11.4%), and congenital heart disease (7 cases, 8.9%). The death rate for patients with underlying disease (27.8%) was significantly greater than the mortality for normal patients with septicaemia (8.9%) (p < 0.05). Meningitis (24.7%) was the most common complication, followed by DIC (19.6%), shock (15.2%), and pneumonia (10.8%). The mortality rate of septicaemia complicated by shock was 66.7% (p < 0.01), and that complicated by DIC was 45.2% (p < 0.01). The mortality rate for patients with the clinical findings of respiratory distress, cough, abdominal distention, cyanosis, splenomegaly, or peripheral coldness was more than 40% and significantly greater (p < 0.01). Mortality rate in patients with granulocyte counts of < 4.000/mm3, platelet counts of < 5 x 10(4)/ mm3, total protein of < 5.0 g/dl, or ESR of < 20 mm/hr were significantly greater (p < 0.01) than those in patients with normal laboratory findings. Coincidence rate of blood and stool cultures was 57.9% for E. coli, and 28.6% for Klebsiella sp., and that of blood and throat cultures was more than 30% for Pseudomonas sp., Haemophilus influenzae, and Staphylococcus aureus. In the study of antimicrobial susceptibility for microorganisms isolated, the number of drug resistant S. aureus had increased in the last 10 years.

The aetiology and outcome of hospitalized patients with moderate to severe community-acquired pneumonia (CAP) were evaluated in 60 adult patients (38 male 22 female, mean age 68.4 years). They were randomized for treatment with either ceftazidime or imipenem/cilastatin intravenously for 7 days. Bacteriological diagnoses were made in 25 cases (41.6%): Streptococcus pneumoniae (5), Haemophilus influenzae (5), Pseudomonas spp. in particular Pseudomonas aeruginosa (8), Staphylococcus aureus (4), Chlamydia spp. (2), Mycobacterium tuberculosis (2) and Moraxella catarrhalis (3); mixed organisms were found in 4 patients. Forty-two patients (70%) responded satisfactorily to the regimens with improvement in sputum purulence cough and dyspnoea scores; there was no difference in response between the two groups. Sixteen patients (26.6%) underwent bronchoscopy on day 4 because of inadequate response to the antibiotics regimens, and 9 of them (15%) required a modification of the initial treatment with addition of erythromycin in 5 patients vancomycin in 1 cloxacillin in 1 and antituberculous drugs in 2. Three out of the 60 patients (5%) died of pulmonary sepsis: the aetiological agents were M. tuberculosis in one, Pseudomonas spp./methicillin-resistant S. aureus in another, but were not identified in the third. We conclude that treatment with either ceftazidime or imipenem/cilastatin was efficacious for moderate to severe CAP in Hong Kong.
