BACKGROUND The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. OBJECTIVE The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for incr...

Occupational rhinitis is characterized by nasal congestion, rhinorrhea, nasal itching, and/or sneezing that occur secondary to exposures in the workplace. This disease can be classified into allergic or nonallergic subgroups based upon the underlying disease pathogenesis as well as the type of causative agent. While the true prevalence of occupational rhinitis is unknown, there are certain prof...

STUDY OBJECTIVES To determine the risk of asthma among patients with occupationally induced rhinitis. DESIGN Patients with confirmed occupational rhinitis were followed for asthma incidence through register linkage. Patients with other occupational diseases were used as a reference population. SUBJECTS Patients entered into the Finnish Register of Occupational Diseases in from 1988 to 1999 ...

Allergic rhinitis, the most common type of rhinitis, generally can be differentiated from the numerous types of nonallergic rhinitis through a thorough history and physical examination. Allergic rhinitis may be seasonal, perennial, or occupational. The most common cause of nonallergic rhinitis is acute viral infection. Other types of nonallergic rhinitis include vasomotor, hormonal, drug-induce...

occupational asthma has been reported  to  be the most  common  chronic respiratory occupational disease in many developed countries, and  as with other  occupational lung diseases, occupational asthma is potentially preventable. we report  the case of a 24-year-old baker who experienced pneumomediastinum as a consequence of workplace exposure. this is the first report of pneumomediastinum as a...

Although adult asthma is attributable to occupational factors and asthma and rhinitis are related, relatively few studies have investigated the prevalence of occupational rhinitis based on occupation, and knowledge of occupational rhinitis in Japan is currently limited. The objective of this cross-sectional study was to estimate the prevalence of allergic rhinitis among Japanese nursing profess...

BACKGROUND Avoidance of occupational allergens or reduction in exposure has been advocated as the mainstay of the management of occupational rhinitis. Sparse data to the effect of allergen avoidance are available. OBJECTIVE To identify factors that may lead to leaving work and to address the effect of subsequent allergen avoidance on quality of life. METHODS A survey to the prevalence of oc...

Occupational rhinitis (OR), a very frequent disease caused by several occupations, tends to share etiological agents and to be three times more prevalent than occupational asthma (OA). Exposure, which can be reliably estimated by means of job description or mean week exposure, may be the single most important determinant of occupational sensitization and OR. Atopy is a controversial risk factor...

A health surveillance study of male grain food manufacturing workers used a respiratory health questionnaire and spirometry to assess the prevalence of work-related respiratory symptoms and impaired ventilatory performance. The prevalence of cough, breathlessness, wheeze and chest tightness was between 8-13% but was 20% for rhinitis. Rhinitis was the most common symptom with 37% of those report...
