Mushroom Worker's Lung

Mushroom Picker Disease


Presentation

  • The first patient presented in respiratory failure, with radiological features characteristic of hypersensitivity pneumonitis.[ncbi.nlm.nih.gov]
  • The etiology of the disease is allergic with a radiographic appearance of alveolitis which may present with consolidation or a reticular pattern. None of the 26 patients exhibited enlargment of the hilar lymph nodes.[ncbi.nlm.nih.gov]
  • Because high numbers of spores of E. flexuosa, T. alba, T. curvata and T. fusca were present in the air that was used for successful inhalation provocation of mushroom workers with MWL and because of the elevated serum titres of these workers, we presume[ncbi.nlm.nih.gov]
  • Compost particles present on several retail Oklahoma mushroom samples purchased from the Tulsa area grocery stores were also spread over Starch Nitrate Agar plates and incubated at 55 C.[citation.allacademic.com]
Camping
  • Straatsma G, Gerrits JPG, Augustijn MPAM, Op den Camp HJM, Vogels GD, Van Griensven LJLD. Population dynamics of Scytalidium thermophilum in mushroom compost and stimulatory effects on growth rate and yield of Agaricus bisporus .[link.springer.com]
Rales
  • The physician would hear fine inspiratory noises, called rales, by auscultation. In the subacute form the shortness of breath and a chronic cough would develop over days or several weeks.[nethealthbook.com]
Allergic Cough
  • HLA class II DPB1, DQA1, DQB1, and DRB1 genotypic associations with occupational allergic cough to Bunashimeji mushroom. Tissue Antigens. 2005;65:459-66[themushroompeople.com]
Arthritis
  • Different control groups, viz, MWL patients employed in the cultivation of the white button mushroom Agaricus bisporus (n 14) and of the oyster mushroom Pleurotus spp (n 3), patients with Bechterew's syndrome (n 7), sarcoidosis (n 7), rheumatoid arthritis[ncbi.nlm.nih.gov]
Neglect
  • I have actually gotten a "mushroom cough" a couple of times...usually when I get busy on other things and neglect blocks in the GH in my man-cave.[shroomery.org]
Urinary Incontinence
  • He has developed and maintained an academic and clinical interest in urinary incontinence, alongside his clinical and educational responsibilities.[books.google.com]

Workup

Thermoactinomyces Vulgaris
  • No antibodies were found against Streptomyces thermovulgaris, Thermoactinomyces vulgaris and T. sacchari nor against the fungi Aspergillus fumigatus, Penicillium brevicompactum, P. chrysogenum, Scytalidium thermophilum and Trichoderma viride.[ncbi.nlm.nih.gov]
  • DNA–DNA relatedness among Thermoactinomyces species: Thermoactinomyces candidus as a synonym of Thermoactinomyces vulgaris and Thermoactinomyces thalpophilus as a synonym of Thermoactinomyces sacchari.[jmm.microbiologyresearch.org]
  • No antibodies were found against Streptomyces thermovulgaris , Thermoactinomyces vulgaris and T. sacchari nor against the fungi Aspergillus fumigatus , Penicillium brevicompactum , P. chrysogenum , Scytalidium thermophilum and Trichoderma viride .[link.springer.com]
  • This may include exposure to Saccharopolyspora rectivirgula, Thermoactinomyces vulgaris, Thermoactinomyces viridis, or Thermoactinomyces sacchari . These species are usually found in decaying organic matter, such as compost, hay or sugar cane.[news-medical.net]
  • Causes: -Farmer’s lung turning mouldy hay or other vegetable material ( Micropolyspora faeni) -Bird fancier’s and pigeon-fancier’s lung (proteins in bird droppings) -Mushroom worker’s lung turning mushroom compost (Thermoactinomyces vulgaris) -Malt worker[clumsylostmedicalstudent.wordpress.com]

Treatment

  • Treatment depends on the type of exposure and the stage of the disease. It may involve medicines, oxygen therapy, or a lung transplant in severe cases.[icdlist.com]
  • Treatment Options If you develop symptoms of hypersensitivity pneumonitis, contact your doctor. Treatment involves avoiding further exposure.[sciencing.com]
  • Some individuals benefit from treatment with corticosteroid medication for acute forms of the disease, although this is less effective for chronic EEA.[news-medical.net]
  • (b) Staphylococcus aureus, Salmonella organisms, Hepatitis B virus Employment where close and frequent contact with a source or sources of the infection has been established and the employment necessitates (1) the treatment, nursing or examination of[bclaws.ca]
  • Treatment The most important thing to do for the patient is to provide respiratory support in terms of intubation and what is called “positive pressure ventilation” with help of a respirator.[nethealthbook.com]

Prognosis

  • -Compensation may be payable Complications: -progressive lung fibrosis -type 1 respiratory failure -pulmonary hypertension and cor pulmonale Prognosis: -the acute form generally resolves if further exposure is prevented -with chronic disease some patients[clumsylostmedicalstudent.wordpress.com]

Etiology

  • The etiology of the disease is allergic with a radiographic appearance of alveolitis which may present with consolidation or a reticular pattern. None of the 26 patients exhibited enlargment of the hilar lymph nodes.[ncbi.nlm.nih.gov]
  • Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.[icd10coded.com]

Pathophysiology

  • Pathophysiology Extrinsic allergic alveolitis is caused by inhalation of antigens that cause a hypersensitivity reaction in the respiratory system.[news-medical.net]

Prevention

  • Prevention of the condition by avoiding or reducing exposure to the allergen is the best course of action.[news-medical.net]
