Rhinitis is a chronic inflammatory disease of the upper respiratory tract, characterized by a high prevalence and a complex pathogenesis. Work-related rhinitis (WRR) can be divided into occupational rhinitis (OR) and work-exacerbated rhinitis (WER). It is not only considered as a disease entity but also in the context of medical certification as the allergic disease associated with occupational...

OBJECTIVES Occupational exposures have been associated with an increased risk of new-onset rhinitis in apprentices. However, population-based prospective data are scarce and do not cover new onset of rhinitis later in life. The authors studied the association between occupational exposure and adult onset of rhinitis prospectively. METHODS The data of 4994 participants (age at follow-up 28-57 ...

Although most cases of food allergy are related to food ingestion, occupational exposure to foods by contact or inhalation may also lead to adverse reactions, inducing contact urticaria or dermatitis, asthma, rhinitis, hypersensitivity pneumonitis, and anaphylaxis. Almost 10–25% of cases of allergic occupational asthma and rhinitis are due to food products. Animal and vegetal highmolecular weig...

Previously we observed an excess risk for occupational asthma among florists with rhinitis. To further evaluate the link between upper and lower airways, we investigated united airways disease in the same occupational group. Occupational history, symptoms and atopy were investigated among 128 florists. Age-, smoking-, and gender-adjusted risks were calculated using logistic regression models co...

Corn is a major staple food, along with rice and wheat, in many parts of the world. There are several reports of hypersensitivity to maize pollen. However, cases of occupational allergic rhinitis induced by inhalation of maize pollen are very rare. We herein report the case of a 67-year-old male with occupational rhinitis caused by occupational exposure to maize pollen in a cornfield. He showed...

Subjects with occupational asthma may also report symptoms of rhinoconjunctivitis. The aims of this study were: 1) to assess the prevalence of rhinoconjunctivitis in association with occupational asthma, and the severity of rhinoconjunctivitis according to the type of agent (high (HMW) and low (LMW) molecular weight agents) causing occupational asthma; and 2) to evaluate the timing of occurrenc...

• The main objectives of the management of occupational rhinitis are, elimination of symptoms and prevention of development of asthma. • Management strategies include, environmental interventions (cessation or reducing the exposure to the causal agent) and appropriate pharmacologic treatment. • Drug therapy does not differ from non-occupational rhinitis. • Given the increased risk for occupatio...

BACKGROUND Numerous studies confirm the association between exposure to indoor air dampness and molds and different health outcomes. Of these, upper respiratory tract problems are the most commonly reported work-related symptoms in damp indoor environments. The aim of this study was to describe a clinically investigated patient series with occupational rhinitis induced by molds. METHODS Nasal...
