1/229. Mushroom worker's lung resulting from indoor cultivation of pleurotus osteatus.Indoor cultivation of oyster mushroom pleurotus osteatus lead to an outbreak of extrinsic allergic alveolitis in two workers. High titer of indirect fluorescent antibody and positive precipitins against basidiospores of P. osteatus were demonstrated in sera of the patients. Mushroom workers should protect themselves from the basidiospores, being aware of their pathogenicity.- - - - - - - - - - ranking = 1keywords = allergic alveolitis, alveolitis (Clic here for more details about this article) |
2/229. Polymyalgia, hypersensitivity pneumonitis and other reactions in patients receiving HMG-CoA reductase inhibitors: a report of ten cases.Ten patients who take hydroxy-methylglutaryl coenzyme a reductase inhibitors, or statin medications, and experience adverse reactions are described. All patients experienced various manifestations of hypersensitivity while receiving the drugs. One patient is described with hypersensitivity pneumonitis, which was graphically demonstrated by both high resolution computerized axial tomography and open lung biopsy.- - - - - - - - - - ranking = 0.045585532348145keywords = pneumonitis (Clic here for more details about this article) |
3/229. mycobacterium sp. as a possible cause of hypersensitivity pneumonitis in machine workers.hypersensitivity pneumonitis (HP) in workers exposed to metal removal fluids (MRFs) is increasing. This study supports the hypothesis that aerosolized mycobacteria colonizing the MRFs likely cause the disease. Three case studies of HP outbreaks among metal workers showed potentially high exposures to a rare and newly proposed mycobacterium species. Retrospective review of samples submitted to our laboratory showed an association between presence of mycobacteria and HP.- - - - - - - - - - ranking = 0.045585532348145keywords = pneumonitis (Clic here for more details about this article) |
4/229. Aerobiological analysis in a salami factory: a possible case of extrinsic allergic alveolitis by penicillium camembertii.A 39-year-old man was hospitalized with a history of fatigue, dyspnoea and low grade fever which seemed to be related to his working environment. The patient was employed in a salami factory, working near the area where the salami are seasoned with fungal inocula. Chest X-ray showed diffuse initial changes of reticulonodular pattern that disappeared after a brief course of steroids therapy. Precipitating antibodies to penicillium notatum and aspergillus fumigatus were found both in plasma and bronchoalveolar lavage fluid. This, together with the finding of a lymphocytic alveolitis with CD4 depletion and CD8 increase, suggested the possibility of extrinsic allergic alveolitis of fungal aetiology. Qualitative and quantitative monitoring with an impinger of both the working and outside environment for aerial fungal concentration demonstrated a very high level of contamination (up to 1.14x10(9) fungal propagules m-3 of air) and an inside/outside ratio from 21 to about 2000. penicillium camembertii was the most common species found in all the indoor sites (60-100% of the fungal load). The patient's BALF and serum both displayed precipitating antibodies to P. camembertii from the powder used for the inoculum and the air samples. These results together with the patient's working history gave some evidence of relationship between the indoor P. camembertii concentration and the patient's symptoms.- - - - - - - - - - ranking = 5.17145835893keywords = allergic alveolitis, alveolitis (Clic here for more details about this article) |
5/229. Extrinsic allergic alveolitis due to rat serum proteins.In a research assistant with recurrent episodes of extrinsic allergic alveolitis on exposure to rats, typical systemic and pulmonary reactions on inhalation and positive reaction on prick testing were elicited only by tests with rat serum; precipitins were present against rat serum and rat pelt, but not rat fur, and were also present against rat urine, which may contain large amounts of serum protein and which may have been a main source of antigenic exposure.- - - - - - - - - - ranking = 5keywords = allergic alveolitis, alveolitis (Clic here for more details about this article) |
6/229. hypersensitivity pneumonitis from Pezizia domiciliana. A case of El Nino lung.A previously healthy woman developed severe dyspnea and was found to have restrictive lung disease and evidence of alveolitis. Open lung biopsy revealed extrinsic allergic alveolitis (hypersensitivity pneumonitis). The etiology was not initially apparent, but a home inspection showed an unusual mushroom growing in the patient's basement. air sampling and serum precipitins against the fungal antigens confirmed that Pezizia domiciliana was the cause of the patient's hypersensitivity pneumonitis. This is the first described case of hypersensitivity pneumonitis cause by P. domiciliana. We speculate that unprecedented rainfall and flooding of the patient's basement as a result of El Nino rains produced ideal factors for the growth of this fungus.- - - - - - - - - - ranking = 1.2352781042174keywords = allergic alveolitis, alveolitis, pneumonitis (Clic here for more details about this article) |
7/229. hypersensitivity pneumonitis associated with co-proxamol (paracetamol dextropropoxyphene) therapy.A 61-year-old man developed hypersensitivity pneumonitis and skin rash in close association with taking co-proxamol. These problems occurred in spite of being treated with prednisolone 40 mg daily (20 mg daily at the time of presentation) for assumed cranial arteritis. A therapeutic challenge with paracetamol was negative and the patient continues to take this drug. It seems likely that this patient's rash and hypersensitivity pneumonitis was caused by dextropropoxyphene. dextropropoxyphene has not been reported previously as a cause of hypersensitivity pneumonitis.- - - - - - - - - - ranking = 0.063819745287403keywords = pneumonitis (Clic here for more details about this article) |
8/229. The invaluable pressure-volume curve.We present a case in which the pressure-volume (P-V) curve proved invaluable in the diagnostic workup of a patient. The patient was a 43-year-old man who presented with progressive dyspnea on exertion, restrictive spirometry, exercise desaturation, and an unremarkable CT scan. Because of the unexpected finding of an unremarkable CT scan, we wanted more data assuring the presence of an indication for lung biopsy. Detailed pulmonary function tests, including a P-V curve, were administered. The P-V curve was abnormal, thus prompting a biopsy, which revealed hypersensitivity pneumonitis. In this report, we discuss the use of P-V curves and the clinical presentation of hypersensitivity pneumonitis.- - - - - - - - - - ranking = 0.018234212939258keywords = pneumonitis (Clic here for more details about this article) |
9/229. hypersensitivity pneumonitis resulting from community exposure to canada goose droppings: when an external environmental antigen becomes an indoor environmental antigen.BACKGROUND: In the past, hypersensitivity pneumonitis has been attributed to occupational, agricultural, or home environmental exposure. OBJECTIVE: This report describes the first case of hypersensitivity pneumonitis due to community exposure to droppings from canada geese migrating through a suburban environment. METHOD: Clinical and serologic information was used in making the diagnosis of hypersensitivity pneumonitis. RESULTS: Serologic analysis demonstrated precipitating antibodies against goose droppings and against an extract made from washings from a filter taken from the patient's office. These studies also showed that the antigens in the office filter were goose dropping antigens. CONCLUSION: hypersensitivity pneumonitis can result from exposure to goose dropping antigens in the community that enter buildings through ventilation systems. This represents a new form of an old disease.- - - - - - - - - - ranking = 0.072936851757031keywords = pneumonitis (Clic here for more details about this article) |
10/229. Two year follow-up of a garbage collector with allergic bronchopulmonary aspergillosis (ABPA).BACKGROUND: Separate collection of biodegradable garbage and recyclable waste is expected to become mandatory in some western countries. A growing number of persons engaged in garbage collection and separation might become endangered by high loads of bacteria and fungi. Case history and examination A 29 year old garbage collector involved in emptying so-called biological garbage complained of dyspnea, fever, and flu-like symptoms during work beginning in the summer of 1992. Chest x-ray showed streaky shadows near both hili reaching into the upper regions. IgE- and IgG-antibodies (CAP, Pharmacia, sweden) were strongly positive for aspergillus fumigatus with 90.5 kU/L and 186%, respectively. Total-IgE was also strongly elevated with 5430 kU/L. Bronchial challenge testing with commercially available aspergillus fumigatus extract resulted in an immediate-type asthmatic reaction. Two years later he was still symptomatic and antibodies persisted at lower levels. CONCLUSIONS: Our diagnosis was allergic bronchopulmonary aspergillosis (ABPA) including asthmatic responses as well as hypersensitivity pneumonitis (extrinsic allergic alveolitis) due to exposure to moldy household waste. A growing number of persons engaged in garbage collection and handling are exposed and at risk to develop sensitization to fungi due to exposure to dust of biodegradable waste. Further studies are necessary to show if separate collection of biodegradable waste increases the health risks due to exposure to bacteria and fungi in comparison to waste collection without separation.- - - - - - - - - - ranking = 1.0091171064696keywords = allergic alveolitis, alveolitis, pneumonitis (Clic here for more details about this article) |
