Respiratory symptoms in Lancashire textile weavers. (1/80)
OBJECTIVES: To investigate a large population of cotton textile weavers for reported respiratory symptoms relative to occupational factors, smoking, and exposure to dust. Cotton processing is known to produce a respiratory disease known as byssinosis particularly in the early processes of cotton spinning. Relatively little is known about the respiratory health of the cotton weavers who produce cloth from spun cotton. By the time cotton is woven many of the original contaminants have been removed. METHODS: 1295 operatives from a target population of 1428 were given an interviewer led respiratory questionnaire. The presence of upper and lower respiratory tract symptoms were sought and the work relatedness of these symptoms determined by a stem questionnaire design. Also occupational and demographic details were obtained and spirometry and personal dust sampling performed. RESULTS: Byssinosis was present in only four people (0.3%). Chronic bronchitis had a moderate overall prevalence of about 6% and was related predominantly to smoking. There were several other work related respiratory symptoms (persistent cough 3.9%, chronic production of phlegm 3.6%, chest tightness 4.8%, wheezing 5.4%, and breathlessness 2.3%). All of these were predicted predominantly by smoking (either past or present), with no consistent independent effect of exposure to dust. Work related eye and nasal symptoms were more common (10.4% and 16.9% respectively). CONCLUSION: Byssinosis is a rare respiratory symptom in cotton weaving. Other work related respiratory symptoms were reported but their presence was predominantly related to smoking with no consistent effects of exposure to dust. (+info)A clinical and radiographic study of coir workers. (2/80)
Processing of coir, which is the fibre obtained from the husk of the coconut, is a dusty procedure; 779 workers in two coir processing factories in Sri Lanka were examined clincally and radiographically for evidence of respiratory disease. Respiratory symptoms were present in 20 (2-6%) of them, which is no higher than in the general population. Respiratory disease such as asthma, chronic bronchitis, byssinosis, and pulmonary tuberculosis which may occur from occupational exposures were considered, but there was no evidence to suggest a definite association between these conditions and coir dust. Twenty-two workers had abnormal chest radiographs, but when compared with a control group of 591 workers from an engineering firm where lesions were found in 20 cases, there was no significant difference. In the opinion of the medical officer, management and workers of the large factory investigated, coir dust does not produce any respiratory disability. The chemical composition of coir dust is similar to that of sisal which is also relatively inert. (+info)Dust exposure in manual flax processing in Egypt. (3/80)
Manual flax processing originated in Egypt in 2 000 BC. In the present study a representative sample of the workers involved in this trade, where flax is processed in small workshops or homes, was examined, and their dust exposure was evaluated. The study showed that workers handling and processing flax are exposed to high concentrations of dust; the levels of dust at hackling and combing are considerably higher than at batting and spinning. Byssinosis prevailed in 22-9% of the examined workers, and 18-4% of them had their forced expiratory volume in one second reduced by more than 10% at the end of the first morning work period (4 hours) of the week. Both the rates and the grades of these syndromes increased with duration of exposure. Smoking appeared to be one of the important contributory factors in the production of byssinosis. The relationship between dust concentration and prevalence of byssinosis seems to be curvilinear. (+info)Pilot study of closing volume in byssinosis. (4/80)
A study of the relative sensitivities of forced expiratory volume in one second (FEV1), maximal mid-expiratory flow (MMF), and closing volume (CV) in the detection of subjects with byssinosis was carried out in a North Carolina cotton mill. Altogether 35 workers participated in the study. Of these, nine showed a decline in FEV1 of 10% or more during the first work shift that followed the weekend break. Twelve subjects showed a decrease in MMF of 15% or more. In contrast only six workers exhibited a 10% increase in closing capacity, while ten showed a 10% increase in CV. Recent evidence of the magnitude of variability in closing volume manoeuvres suggests that our chosen level of change was too low, A 40% change in CV would have identified only five subjects. CV is a more complex manoeuvre for the subject being tested and for the technician to perform, is more time consuming, and is subject to greater variation. To have any advantage over spirometry, CV would have to be appreciably more sensitive. Our study suggests that it is not. However, the MMF may prove to be more sensitive than the FEV1 in the detection of byssinosis. (+info)An evaluation of effect of airborne dust from a cotton mill on the guinea-pig ileum with reference to byssinosis. (5/80)
The effect of airborne dust on the guinea-pig ileum was studied. Tyrode extracts of airborne dust collected freshly in the cardroom of a cotton mill, and extracts of air pollutant samples drawn on the roof of the mill and of the local town hall were all found to induce the guinea-pig ileum to contract when applied in a tissue-bath. However, the force of contraction with air pollutants was rather greater than that with the cardroom dust. Considering the variables involved, the ileum response to the cardroom dust may have been due to ordinary air pollutants which constitute a significant part of the dust. It is concluded that this pharmacological phenomenon is probably not relevant in the context of byssinosis. (+info)Prevalence of byssinosis and respiratory symptoms among cotton mill workers. (6/80)
BACKGROUND: While the prevalence of byssinosis is decreasing in industrialized countries and persists at high levels in developing countries, this prevalence is remaining constant in Turkey. OBJECTIVE: In order to determine the effects of past cotton dust exposure on the respiratory tract, a total of 223 persons working in a cotton mill were included in this study. METHODS: A questionnaire was used to inquire about respiratory symptoms. Participants underwent several spirometric measurements, which were performed on the 1st, 3rd and 5th day of the working week. Cotton dust measurements were performed in different divisions of the factory. RESULTS: The most common respiratory symptom was chest tightness (20.3%). The prevalence of byssinosis was 14.2% in cotton-processing workers. Among these cases, 28.6% had symptoms on the 1st day of the week, and 71.4% had symptoms on all days of the week. An acute effect was seen in 53.6% of the workers with byssinosis. Mean respirable dust levels were between 0.095 and 0.413 mg/m(3). CONCLUSIONS: In spite of technological improvements, respirable dust concentrations are still above the permissible limits, and thus the risk of byssinosis remains. Workers in the cotton industry where obsolete technology is used and standardized protection measures are not applied should be followed for byssinosis. (+info)Comparative study of the smooth muscle contractor activity of airborne dusts and of dustiness in cotton, flax, and jute mills. (7/80)
A bioassay technique using isolated guinea-pig ileum was employed to compare the smooth muscle contractor activity of various dusts from mills in which the prevalence of byssinosis was known. The activity of dust from a mill spinning a coarse grade of cotton was several times greater than that in dust from a mill processing a fine grade of cotton. There was a similar order in the difference of the prevalence of byssinosis in these mills. However, the activities of fine cotton, flax, and jute dusts were very similar to each other, in spite of marked differences in the prevalence of byssinosis in these mills. For cotton dust, smooth muscle contractor activity was associated with all particle sizes, although the lowest level of activity was found in the largest sized fraction (less than 2 mm). Activity in the cotton dust extracts was not correlated with nitrogen, carbohydrate, or potassium content. However, about one-fifth of the activity of a cotton dust extract was associated with an insoluble particulate fraction. The possible chemical nature of the water-soluble contractor agent is discussed. It is concluded that, until the role of this agent in the pathogenesis of byssinosis has been established, the bioassay technique cannot be employed as a means of assessing the byssinogenic potential of cotton dust. (+info)Epidemiological investigation of the role of family susceptibility and occupational and family histories in the development of byssinosis among workers exposed to flax dust. (8/80)
Epidemiological investigation of 475 workers exposed to dust in flax processing has shown that family susceptibility has a decisive role in the development of byssinosis in those workers. Workers whose fathers had occupational history of exposure to flax dust were more resistant to the development of the disease than those whose fathers had no such history. Such tolerance was much higher in workers whose fathers were byssinotic than those with byssinosis-free fathers. Further hereditary and immunological investigations are, however, needed. (+info)Byssinosis is a respiratory condition that primarily affects textile workers who are exposed to high levels of cotton, flax, or hemp dust. It's also known as brown lung disease. The medical definition of byssinosis is:
A restrictive lung disease characterized by chest tightness, cough, and shortness of breath that typically occurs in workers exposed to high levels of organic dust from cotton, flax, or hemp. The symptoms usually appear after the first day of exposure (known as "Monday fever") and improve with continued exposure during the week, only to recur again at the beginning of the next workweek. Chronic byssinosis can lead to progressive shortness of breath, chronic cough, and significant lung function impairment. The exact mechanism by which the dust causes the disease is not fully understood but may involve an immune response or direct toxicity to the airways.
I'm sorry for any confusion, but "Textile Industry" and "medical definition" are not related. The textile industry is the overall system of designing, producing, and distributing clothing and their raw materials, which include fiber, yarn, and cloth. It involves several processes such as spinning, weaving, knitting, dyeing, and finishing.
If you're looking for a medical term or definition, please provide me with the term so I can assist you better.
"Gossypium" is the scientific name for the cotton plant. It belongs to the Malvaceae family and is native to tropical and subtropical regions around the world. The cotton plant produces soft, fluffy fibers that are used to make a wide variety of textiles, including clothing, bedding, and other household items.
The medical community may use the term "Gossypium" in certain contexts, such as when discussing allergic reactions or sensitivities to cotton products. However, it is more commonly used in botany and agriculture than in medical terminology.
In medical terms, "dust" is not defined as a specific medical condition or disease. However, generally speaking, dust refers to small particles of solid matter that can be found in the air and can come from various sources, such as soil, pollen, hair, textiles, paper, or plastic.
Exposure to certain types of dust, such as those containing allergens, chemicals, or harmful pathogens, can cause a range of health problems, including respiratory issues like asthma, allergies, and lung diseases. Prolonged exposure to certain types of dust, such as silica or asbestos, can even lead to serious conditions like silicosis or mesothelioma.
Therefore, it is important for individuals who work in environments with high levels of dust to take appropriate precautions, such as wearing masks and respirators, to minimize their exposure and reduce the risk of health problems.
Cotton fiber is not a medical term, but I can provide you with some information about cotton fibers in a general context.
Cotton fibers are soft, fluffy staple fibers that grow in a protective case called a boll around the seeds of cotton plants. Cotton fibers are primarily composed of cellulose, which is an organic compound and the main structural component of plant cells. These fibers are typically spun into yarn or thread and used to make a wide variety of textiles, including clothing and other soft goods.
Cotton fibers have some unique properties that make them suitable for medical applications as well:
1. Hypoallergenic: Cotton is generally considered hypoallergenic, meaning it is less likely to cause an allergic reaction compared to other materials. This makes cotton a popular choice for medical bandages, swabs, and other products that come into contact with the skin.
2. Absorbent: Cotton fibers are highly absorbent, which can be useful in medical settings for managing wounds, incontinence, or excessive sweating.
3. Breathable: Cotton is a breathable material, allowing air to pass through and helping to maintain a comfortable body temperature. This property makes cotton an excellent choice for medical garments, bedding, and other products that require good ventilation.
4. Comfortable: Cotton fibers are soft, lightweight, and gentle on the skin, making them a preferred material for medical textiles and clothing designed for people with sensitive skin or medical conditions like eczema or dermatitis.
5. Durable: Although cotton fibers can be delicate when wet, they are relatively strong and durable in dry conditions. This makes cotton an appropriate choice for reusable medical products like gowns, scrubs, and linens.
Tannins, also known as tannic acid or gallotannins, are a type of polyphenolic biomolecule found in plants. They are most commonly known for their ability to bind to proteins and other organic compounds, forming insoluble complexes. This property is what gives tannins their characteristic astringent taste and is also the basis for their use in traditional medicine and industry.
In the context of human health, tannins have been studied for their potential beneficial effects on various physiological processes, such as antioxidant activity, anti-inflammatory effects, and inhibition of enzymes involved in cancer development. However, excessive consumption of tannins can also have negative health effects, including stomach irritation, nausea, and liver damage.
Tannins are found in a wide variety of plants, including fruits, vegetables, grains, nuts, bark, leaves, and roots. They are particularly abundant in certain types of food and beverages, such as red wine, tea, coffee, chocolate, and some herbs and spices. In the medical field, tannins have been used topically for their astringent properties to treat wounds, burns, and skin irritations. However, it is important to note that the evidence supporting the health benefits of tannins is still limited and more research is needed to fully understand their effects on human health.
Bronchitis is a medical condition characterized by inflammation of the bronchi, which are the large airways that lead to the lungs. This inflammation can cause a variety of symptoms, including coughing, wheezing, chest tightness, and shortness of breath. Bronchitis can be either acute or chronic.
Acute bronchitis is usually caused by a viral infection, such as a cold or the flu, and typically lasts for a few days to a week. Symptoms may include a productive cough (coughing up mucus or phlegm), chest discomfort, and fatigue. Acute bronchitis often resolves on its own without specific medical treatment, although rest, hydration, and over-the-counter medications to manage symptoms may be helpful.
Chronic bronchitis, on the other hand, is a long-term condition that is characterized by a persistent cough with mucus production that lasts for at least three months out of the year for two consecutive years. Chronic bronchitis is typically caused by exposure to irritants such as cigarette smoke, air pollution, or occupational dusts and chemicals. It is often associated with chronic obstructive pulmonary disease (COPD), which includes both chronic bronchitis and emphysema.
Treatment for chronic bronchitis may include medications to help open the airways, such as bronchodilators and corticosteroids, as well as lifestyle changes such as smoking cessation and avoiding irritants. In severe cases, oxygen therapy or lung transplantation may be necessary.
Occupational air pollutants refer to harmful substances present in the air in workplaces or occupational settings. These pollutants can include dusts, gases, fumes, vapors, or mists that are produced by industrial processes, chemical reactions, or other sources. Examples of occupational air pollutants include:
1. Respirable crystalline silica: A common mineral found in sand, stone, and concrete that can cause lung disease and cancer when inhaled in high concentrations.
2. Asbestos: A naturally occurring mineral fiber that was widely used in construction materials and industrial applications until the 1970s. Exposure to asbestos fibers can cause lung diseases such as asbestosis, lung cancer, and mesothelioma.
3. Welding fumes: Fumes generated during welding processes can contain harmful metals such as manganese, chromium, and nickel that can cause neurological damage and respiratory problems.
4. Isocyanates: Chemicals used in the production of foam insulation, spray-on coatings, and other industrial applications that can cause asthma and other respiratory symptoms.
5. Coal dust: Fine particles generated during coal mining, transportation, and handling that can cause lung disease and other health problems.
6. Diesel exhaust: Emissions from diesel engines that contain harmful particulates and gases that can cause respiratory and cardiovascular problems.
Occupational air pollutants are regulated by various government agencies, including the Occupational Safety and Health Administration (OSHA) in the United States, to protect workers from exposure and minimize health risks.

Dust14
- Byssinosis is an occupational lung disease caused by inhalation of cotton or jute dust in inadequately ventilated working environments and can develop over time with repeated exposure. (wikipedia.org)
- Later in the 1978 OSHA developed the Cotton Dust Standard which aimed to prevent occupational respiratory disease, such as byssinosis, through medical monitoring of employees. (wikipedia.org)
- However, a NISOH sponsored committee remained apprehensive about this standard as an earlier study conducted by NIOSH found that byssinosis diagnoses were brought on by cotton dust levels as low as 0.1 mg/m3 meaning that there is still a risk for the development of byssinosis for cotton dust exposure under the PEL. (wikipedia.org)
- Byssinosis can become chronic in a patient if they are continually exposed to cotton, jute, or yarn dust over time. (wikipedia.org)
