Aim: The aim of this study was to assess the knowledge regarding prevention bronchial asthma among workers in JK cement factory Kashmir.Introduction: Occupational refers induced by exposure working environment airborne dusts, vapors, or fumes, with without preexisting asthma.. Over 250 materials encountered at workplace can cause occupational asthma, which accounts for about 15% all cases. Meth...

Workplace exposures may result, in susceptible workers, in the development of occupational asthma from sensitising or toxic/irritant exposure, or in the worsening of a pre-existing asthmatic condition, so-called ‘‘work-exacerbated asthma’’ [1–3]. Occupational asthma is a relatively common condition, although it is often unrecognised [1, 4]. Exposure to the sensitising agents can lead to permane...

BACKGROUND Occupational non-malignant respiratory disease arises from exposure of workers to airborne agents, mostly particulate or dusts. We describe the worldwide mortality and morbidity from asthma, chronic obstructive pulmonary disease (COPD), and pneumoconioses arising from these occupational exposure and focus on cases reported in the year 2000. METHODS The proportions of workers expose...

There are differences in the management of workers with work-related asthma within Canadian provinces. In Quebec, the compensation of a case of occupational asthma is usually based on the positivity of a specific inhalation challenge, whereas in Ontario, the diagnosis is usually based on serial peak expiratory flow (PEF), provocative methacholine concentration causing a 20% decrease in forced e...

Occupational asthma among hairdressers has been recognised for some years and cases of work related asthma due to hair bleaches containing persulphates and hair dyes have been reported. The extent of the disease among hairdressers remains unknown. An investigation was carried out on an entire hairdressing salon, which specialised in hair bleaching and colouring and which employed 23 staff. On t...

European Respiratory Society guidelines on the management of work-related asthma recommend that occupational asthma with an allergic mechanism should be diagnosed by both identifying the workplace as the cause, and confirming sensitisation to the asthmagen by specific inhalational challenge (SIC), in the absence of any available specific IgE tests [1, 2]. Used (contaminated) metalworking fluid ...

International reviews suggest that the median proportion of adult cases of asthma attributable to occupational exposure is between 10% and 15%. Therefore, it is essential that clinicians have a broad knowledge of the various causes associated with occupational asthma. Occupational asthmagens are categorized as low-molecular-weight (LMW, ≤1000 kd) and high-molecular-weight (HMW, ≥1000 kd) antige...

A large number of agents in the workplace have been shown to give rise to occupational asthma. With the rapid introduction of new compounds into industries, it is likely that the prevalence of occupational asthma will continue to increase. This condition may well exceed pneumoconiosis as the most important cause of occupational lung disease. During the past two decades, there have been many stu...
