Farmer's lung is a form of hypersensitivity pneumonitis, which is manifested mainly as an occupational disease among dairy farmers exposed to organic dusts from moldy hay and compost in silos and lofts. In Europe and America, it has been known for many years. In Japan, it frequently occurs in Hokkaido, Iwate and Hokuriku districts during winter months from November to March. The culprit antigens are spores of actinomycetes thermophilus such as Micropolyspora faeni and Thermoactinomyces vulgaris. In recent years, various preventive measures have been taken. For instance, in order to prevent hay from heating by fermentation and the thermophile from thriving, farmers desiccate hay as much as possible and keep it in air-tight plastic containers. The result is a notable decrease in the prevalence rate of this ailment. Nonetheless, with graying the rural population, pulmonary fibrosis caused by chronic exposure to low levels of organic dust is posing a grave health problem in the dairy farming communities. As a prophylactic measure against chronic fibrotic lung disease, there is a need to implement a comprehensive heath control program consisting of continual sanitary checkups at workplace and counseling at an early stage in addition to periodic health examinations. Another health threat which has more recently loomed up in the dairy farming communities is environmental pollution.

In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise. Findings obtained in several imaging examinations led to a diagnosis of facial asymmetry associated with right mandibular condyle hyperplasia. Following 3 months of preoperative orthodontic treatment, in October 2018 under general anesthesia the patient underwent a right mandibular condylectomy, Le Fort I osteotomy, right mandibular sagittal split ramus osteotomy, and left mandibular inverted L ramus osteotomy. In examinations up to 3 years after surgery, good results were noted.For this case of severe facial asymmetry with mandibular condyle hyperplasia, early surgery and condylectomy were performed simultaneously to significantly shorten the total treatment time. The effectiveness of a surgery-early approach was confirmed by no postoperative findings indicating abnormalities in the TMJ or retroversion.
