Abstract
BACKGROUND Antigen avoidance (AA) is essential for people with hypersensitivity pneumonitis (HP). An intervention programme to promote continuous AA in people with HP will be the focus of future research. OBJECTIVES We systematically analysed the AA behaviour of people with HP, interventions of health-care providers to promote AA behaviour, clinical outcomes after AA, and evaluation methods after AA. METHODS We conducted a scoping review using six online databases and manual searches. Papers written in English or Japanese that reported cases on AA were selected. The extracted data were classified qualitatively. RESULTS In total 205 cases included in 109 eligible papers were examined. CONCLUSIONS This review clarified the fundamental evidence of AA in people with HP. These people required the continuous support of health-care providers to continue appropriate AA. This review highlighted four aspects that require further research to design interventions for promoting effective and continuous AA in people with HP.

Abstract
Bird Fancier's Lung is a type of hypersensitivity pneumonitis, an immunologically mediated lung disease due to repetitive exposure of air-borne avian antigen. This was first described in 1965 and is known as one of the most common causes of hypersensitivity pneumonitis. This case highlights this underdiagnosed etiology of dyspnea, disease presentation and exposure variability, and methods of diagnosis.

Abstract
Hypersensitivity pneumonitis (HP) is a complex syndrome caused by the inhalation of a variety of antigens in susceptible and sensitized individuals. These antigens are found in the environment, mostly derived from bird proteins and fungi. The prevalence and incidence of HP vary widely depending on the intensity of exposure, the geographical area and the local climate. Immunopathologically, HP is characterized by an exaggerated humoral and cellular immune response affecting the small airways and lung parenchyma. A complex interplay of genetic, host and environmental factors underlies the development and progression of HP. HP can be classified into acute, chronic non-fibrotic and chronic fibrotic forms. Acute HP results from intermittent, high-level exposure to the inducing antigen, usually within a few hours of exposure, whereas chronic HP mostly originates from long-term, low-level exposure (usually to birds or moulds in the home), is not easy to define in terms of time, and may occur within weeks, months or even years of exposure. Some patients with fibrotic HP may evolve to a progressive phenotype, even with complete exposure avoidance. Diagnosis is based on an accurate exposure history, clinical presentation, characteristic high-resolution CT findings, specific IgG antibodies to the offending antigen, bronchoalveolar lavage and pathological features. Complete antigen avoidance is the mainstay of treatment. The pharmacotherapy of chronic HP consists of immunosuppressive drugs such as corticosteroids, with antifibrotic therapy being a potential therapy for patients with progressive disease.

Abstract
BACKGROUND Hypersensitivity pneumonitis (HP) is a rare interstitial lung disease in children, and very little data are available on the frequency, diagnosis, and outcomes of HP. In a pediatric cohort with HP, the characteristics of the CD4/CD8 lymphocyte ratio are often described as nonspecific. METHODS We used the National French Database (RespiRare) to collect data from the last decade on HP. The diagnosis of HP was defined by the presence of a relevant exposure, clinical symptoms, and compatible lung imaging radiology and was usually defined by positive precipitins antibodies. RESULTS A total of 16 children with a mean age of 10 years (4-13) presented with HP. All children presented with dyspnea on exertion. Diffuse ground-glass opacity was present in all computed tomography (CT) scans. Research guided by a questionnaire and precipitins antibodies against the corresponding antigens showed that patients were positive for contact with birds with or without fungi. Bronchoalveolar lavage (BAL) was performed in 12 children. The total cell counts were elevated in BAL fluid, with a mean value of 36% lymphocytes. The CD4/CD8 lymphocyte ratio was below one for all children. CONCLUSION BAL in our pediatric cohort with HP had the same characteristics as that of adults with HP. An HP diagnosis must be considered when dyspnea on exertion and diffuse ground-glass opacity are observed. Carrying out BAL and serological tests can help diagnose and avoid lung biopsy.

Abstract
Bird related hypersensitivity pneumonitis (HP) is becoming more common than other forms of HP around the world. We present two cases of HP, associated with exposure to visiting birds which had nested within their homes in semi urban areas of Colombo, Sri Lanka. A 65-year-old female (case 1) and a 61-year-old male (case 2) presented to the chest clinic complaining of gradually progressive and persistent chronic dry cough and dyspnoea during the year 2018. Both were found to have close contact with red-vented bulbuls (Konda kurulla) in their homes for more than 6 months prior to onset of symptoms and denied any other risk exposures in detail history taking. In both patients, high-resolution computed tomography chest (HRCT) showed centrilobular nodules of ground glass density with significant lobular air trapping. Video-assisted thoracoscopic (VATs) lung biopsy of case 1 showed patchy and focal interstitial thickening with lymphocytic infiltrate, minimal fibrosis, and few noncaseating granulomata within the interstitium. Transbronchial lung biopsy of case 2 showed thickened alveolar septae with lympho-histiocytic infiltrate and occasional neutrophils and eosinopils. Both showed severe reduction in forced vital capacity (FVC) at presentation. Multidisciplinary diagnosis of HP associated with red-vented bulbuls was made. Both achieved good improvement in clinical, lung function, and radiological assessment following removal of offending antigen exposure and treatment with oral corticosteroids.

Abstract
Widespread food poisoning due to microbial contamination has been a major concern for the food industry, consumers and governing authorities. This study is designed to determine the levels of fungal contamination in edible bird nests (EBNs) using culture and molecular techniques. Raw EBNs were collected from five house farms, and commercial EBNs were purchased from five Chinese traditional medicine shops (companies A-E) in Peninsular Malaysia. The fungal contents in the raw and commercial EBNs, and boiled and unboiled EBNs were determined. Culturable fungi were isolated and identified. In this study, the use of these methods revealed that all EBNs had fungal colony-forming units (CFUs) that exceeded the limit set by Standards and Industrial Research Institute of Malaysia (SIRIM) for yeast and moulds in EBNs. There was a significant difference (p < 0.05) in the number of types of fungi isolated from raw and commercial EBNs, but no significant difference in the reduction of the number of types of fungi after boiling the EBNs (p > 0.05). The types of fungi isolated from the unboiled raw EBNs were mainly soil, plant and environmental fungi, while the types of fungi isolated from the boiled raw EBNs, unboiled and boiled commercial EBNs were mainly environmental fungi. Aspergillus sp., Candida sp., Cladosporium sp., Neurospora sp. and Penicillum sp. were the most common fungi isolated from the unboiled and boiled raw and commercial EBNs. Some of these fungi are mycotoxin producers and cause opportunistic infections in humans. Further studies to determine the mycotoxin levels and methods to prevent or remove these contaminations from EBNs for safe consumption are necessary. The establishment and implementation of stringent regulations for the standards of EBNs should be regularly updated and monitored to improve the quality of the EBNs and consumer safety.

Abstract
PATIENT Female, 60 FINAL DIAGNOSIS: Bird fanciers' lung Symptoms: Cough productive • hypoxia • short of breath • substernal chest pain MEDICATION - Clinical Procedure: - Specialty: - OBJECTIVE Rare disease. BACKGROUND Hypersensitivity pneumonitis (HP) is a group of inflammatory interstitial lung diseases caused by hypersensitivity reactions from repeated insults of inhalation of fine particulate organic dusts derived from environmental sources. Bird fanciers' lung (BFL) is the most common form of HP, with an estimated prevalence of 0.5-7.5% and is observed in individuals who develop a hypersensitivity response to avian droppings or antigens on bird feathers. CASE REPORT A 60-year-old woman presented to our care with shortness of breath with exertion. She was hypoxic with oxygen saturation of 70% on room air. The CTA of the chest revealed a diffuse bilateral ground glass density in the lung parenchyma with a mosaic attenuation pattern. On further questioning she explained that she collected many duck and goose feathers she found on the ranch and placed them in a vase at home. Transbronchial lung biopsy revealed non-caseating granulomas, aggregates of epithelioid macrophages, and patchy mononuclear cell infiltration with lymphocytes and fibrotic tissue. The patient clinically improved and was discharged home on the 6(th) hospital day with prednisone 20 mg daily, with clinical improvement noted on subsequent follow up visits. CONCLUSIONS There is no specific clinical manifestation; abnormal laboratory test results help establish a definitive diagnosis. The best diagnostic tool is the correlation of symptom onset with the environmental exposure. The prognosis is excellent after a single episode of HP, but continuous re-exposure carries the risk of progressive pulmonary impairment.

Abstract
The prevalence of exotic pet allergies has been increasing over the last decade. Years ago, the main allergy-causing domestic animals were dogs and cats, although nowadays there is an increasing number of allergic diseases related to insects, rodents, amphibians, fish, and birds, among others. The current socio-economic situation, in which more and more people have to live in small apartments, might be related to this tendency. The main allergic symptoms related to exotic pets are the same as those described for dog and cat allergy: respiratory symptoms. Animal allergens are therefore, important sensitizing agents and an important risk factor for asthma. There are three main protein families implicated in these allergies, which are the lipocalin superfamily, serum albumin family, and secretoglobin superfamily. Detailed knowledge of the characteristics of allergens is crucial to improvement treatment of uncommon-pet allergies.

Abstract
Zoonotic transmission of disease from pet birds is uncommon, but there are some recognized dangers. Most notably, Chlamydophila psittaci can be transmitted from pet birds to humans. Allergic responses to pet birds, including pneumonitis and contact dermatitis, have also been documented. Bite wounds from pet birds are rarely reported but can cause trauma and develop infection. The other diseases discussed here are considered potential zoonotic diseases of pet birds because of either isolated reports of suspected but unconfirmed transmission to humans or from reports of wild conspecifics being reported to have the disease.

Abstract
PURPOSE OF REVIEW To bring readers up to date on recent reports, both clinical and basic understanding, on hypersensitivity pneumonitis. RECENT FINDINGS Although many antigens and environmental settings have already been described as sources of this hyperimmune pulmonary disease, the literature continues to bring forth other conditions that can cause hypersensitivity pneumonitis. We also highlight new findings in the diagnosis of hypersensitivity pneumonitis, its histopathology, insight into its potential outcomes, and understanding of its immune mechanisms that could lead to new treatments. SUMMARY The review will help clinicians in their diagnostic approach to hypersensitivity pneumonitis and lead them to look for other potential sources of the disease. The findings described will help guide further research on the pathophysiology and seek new treatments for this worldwide orphan disease.

Abstract
A 51-year old woman developed hypersensitivity pneumonitis (HP) after inhaling the excrement of starlings that populated a park adjacent to her home. The clinical symptoms consisted of a non-productive cough and grade II dyspnea and radiological interstitial micronodular involvement. The respiratory function tests showed a restrictive pattern with desaturation on effort and a biopsy using videothorascopy was highly suggestive of HP. After taking a very detailed clinical history the patient mentioned an increase in cough when she crossed a park near her home, where a high population of starlings lived in its trees. Specific antigen extracts were prepared and skin tests were performed, precipitins measured, and bronchial provocation tests specific to this antigen were all positive. This observation identified a species of bird capable of causing the disease and shows a lung disease secondary to the exposure of a not very large but persistent antigen load.
