Exposure to indoor background radiation and urinary concentrations of 8-hydroxydeoxyguanosine, a marker of oxidative DNA damage. (1/20)

We investigated whether exposure to indoor [gamma]-radiation and radon might be associated with enough free radical formation to increase urinary concentrations of 8-hydroxydeoxyguanosine (8-OHdG), a sensitive marker of DNA damage, due to a hydroxyl radical attack at the C8 of guanine. Indoor radon and [gamma]-radiation levels were measured in 32 dwellings for 6 months by solid-state nuclear track detectors and thermoluminescent dosimeters, respectively. Urine samples for 8-OHdG determinations were obtained from 63 healthy adult subjects living in the measured dwellings. An overall tendency toward increasing levels of 8-OHdG with increasing levels of radon and [gamma]-radiation was seen in the females, presumably due to their estimated longer occupancy in the dwellings measured. Different models were considered for females, with the steepest slopes obtained for [gamma]-radiation with a coefficient of 0.500 (log nmol/l of 8-OHdG for each unit increase of [gamma]-radiation on a log scale) (p<0.01), and increasing to 0.632 (p = 0.035), but with larger variance, when radon was included in the model. In conclusion, there seems to be an effect of indoor radioactivity on the urinary excretion of 8-OHdG for females, who are estimated to have a higher occupancy in the dwellings measured than for males, for whom occupational and other agents may also influence 8-OHdG excretion. ree radicals; [gamma]-radiation; radon.  (+info)

Cancer risk around the nuclear power plants of Trillo and Zorita (Spain). (2/20)

AIM: To investigate the association between cancer risk and proximity of place of residence to the Guadalajara nuclear power plants: Trillo and Zorita. METHODS: Case-control study. Cases were patients admitted with cancer and controls were non-tumorous patients, both admitted to Guadalajara Hospital (period 1988-99). Exposure factor: place of residence (areas within 10, 20, and 30 km of each plant). Odds ratios (ORs) of those areas closest to the plants were calculated with respect to those furthest away; a linear trend analysis was also performed. RESULTS: In the extreme areas in the vicinity of Trillo, an OR of 1.71 was obtained (95% CI 1.15 to 2.53), increasing in magnitude in the subgroup of more radioinducible tumours and in the period considered as post-latency (1997-99). Risk increased linearly with proximity to the two plants, significantly in Trillo (p < 0.01) but not in Zorita (p = 0.19). CONCLUSIONS: There is an association between proximity of residence to Trillo and cancer risk, although the limitations of the study should be kept in mind when interpreting the possible causal relation.  (+info)

RADIATION PROTECTION IN CANADA. III. THE ROLE OF THE RADIATION PROTECTION DIVISION IN SAFEGUARDING THE HEALTH OF THE PUBLIC. (3/20)

The current status of radiation protection in Canada is discussed in the last of a three-part series. Particular emphasis has been placed on the role of the Radiation Protection Division of the Department of National Health and Welfare. A radioactive fallout study program has been established involving the systematic collection of air and precipitation samples from 24 locations, soil samples from 23 locations, fresh-milk samples from 16 locations, wheat samples from nine areas and human-bone specimens from various hospitals throughout Canada. A whole-body-counting facility and a special study of fallout in Northern areas have also been initiated. For any age group, the highest average strontium-90 concentration in human bone so far reported has been less than four picocuries per gram of calcium compared with the maximum permissible level of 67 derived from the International Committee on Radiation Protection (ICRP) recommendations. By the end of 1963 a general downward trend of levels of radioactivity detected in other parts of the program has been observed. Programs to assess the contribution to the radiation exposure of members of the population from medical x-rays, nuclear reactor operations and natural background-radiation sources have also been described. The annual genetically significant dose from diagnostic x-ray examinations in Canadian public hospitals has been estimated to be 25.8 mrem. Results from the reactor-environment monitoring programs have not suggested the presence of radioactivity beyond that contributed from fallout.  (+info)

Radon in homes and risk of lung cancer: collaborative analysis of individual data from 13 European case-control studies. (4/20)

OBJECTIVE: To determine the risk of lung cancer associated with exposure at home to the radioactive disintegration products of naturally occurring radon gas. DESIGN: Collaborative analysis of individual data from 13 case-control studies of residential radon and lung cancer. SETTING: Nine European countries. SUBJECTS: 7148 cases of lung cancer and 14,208 controls. MAIN OUTCOME MEASURES: Relative risks of lung cancer and radon gas concentrations in homes inhabited during the previous 5-34 years measured in becquerels (radon disintegrations per second) per cubic metre (Bq/m3) of household air. RESULTS: The mean measured radon concentration in homes of people in the control group was 97 Bq/m3, with 11% measuring > 200 and 4% measuring > 400 Bq/m3. For cases of lung cancer the mean concentration was 104 Bq/m3. The risk of lung cancer increased by 8.4% (95% confidence interval 3.0% to 15.8%) per 100 Bq/m3 increase in measured radon (P = 0.0007). This corresponds to an increase of 16% (5% to 31%) per 100 Bq/m3 increase in usual radon--that is, after correction for the dilution caused by random uncertainties in measuring radon concentrations. The dose-response relation seemed to be linear with no threshold and remained significant (P = 0.04) in analyses limited to individuals from homes with measured radon < 200 Bq/m3. The proportionate excess risk did not differ significantly with study, age, sex, or smoking. In the absence of other causes of death, the absolute risks of lung cancer by age 75 years at usual radon concentrations of 0, 100, and 400 Bq/m3 would be about 0.4%, 0.5%, and 0.7%, respectively, for lifelong non-smokers, and about 25 times greater (10%, 12%, and 16%) for cigarette smokers. CONCLUSIONS: Collectively, though not separately, these studies show appreciable hazards from residential radon, particularly for smokers and recent ex-smokers, and indicate that it is responsible for about 2% of all deaths from cancer in Europe.  (+info)

Archeo-cell biology: carbon dating is not just for pots and dinosaurs. (5/20)

Defining the life span of specific human cell populations is limited by our inability to mark the exact time when cells are born in a way that can be detected over many years. In this issue of Cell, Spalding et al. (2005) describe a clever strategy for retrospectively birth dating human cells in vivo, based on their incorporation of 14C during a peak in atmospheric levels of this isotope resulting from above-ground nuclear arms testing in the 1950s.  (+info)

Indoor radon and lung cancer. Estimating the risks. (6/20)

Radon is ubiquitous in indoor environments. Epidemiologic studies of underground miners with exposure to radon and experimental evidence have established that radon causes lung cancer. The finding that this naturally occurring carcinogen is present in the air of homes and other buildings has raised concern about the lung cancer risk to the general population from radon. I review current approaches for assessing the risk of indoor radon, emphasizing the extrapolation of the risks for miners to the general population. Although uncertainties are inherent in this risk assessment, the present evidence warrants identifying homes that have unacceptably high concentrations.  (+info)

Indoor-atmospheric radon-related radioactivity affected by a change of ventilation strategy. (7/20)

The present author has kept observation for concentrations of atmospheric radon, radon progeny and thoron progeny for several years at the campus of Fukushima Medical University. Accidentally, in the midst of an observation term, i.e., February 2005, the facility management group of the university changed a strategy for the manner of ventilation, probably because of a recession: (I) tidy everyday ventilation of 7:30-24:00 into (II) shortened weekday ventilation of 8: 00-21 : 00 with weekend halts. This change of ventilation manner brought a clear alteration for the concentrations of radon-related natural radioactivity in indoor air. The present paper concerns an investigation of the effect of the ventilation strategy on the indoor-atmospheric radon-related radioactivity.  (+info)

Indoor radon concentrations and assessment of doses in four districts of the Punjab Province - Pakistan. (8/20)

Seasonal indoor radon measurement studies have been carried out in four districts, namely, Jhelum, Chakwal, Rawalpindi and Attock of the Punjab Province. In this regard, CR-39 based detectors were installed in bedrooms, drawing rooms and kitchens of 40 randomly selected houses in each district. After exposing to radon in each season, CR-39 detectors were etched in 6M NaOH at 80 degrees C and counted under an optical microscope. Indoor radon activity concentrations in the houses surveyed ranged from 15 +/- 4 to 176 +/- 7 Bq m(-3) with an overall average value of 55 +/- 31 Bq m(-3). The observed annual average values are greater than the world average of 40 Bq m(-3). Maximum indoor radon concentration levels were observed in winter season whereas minimum levels were observed in summer season. None of the measured radon concentration value exceeded the action level of 200-400 Bq m(-3). The season/annual ratios for different type of dwellings varied from 0.87 +/- 0.93 to 1.14 +/- 1.10. The mean annual estimated effective dose received by the residents of the studied area was found to be 1.39 +/- 0.78 mSv. The annual estimated effective dose is less than the recommended action level (3-10 mSv).  (+info)

9. Tuberculosis (TB): A bacterial infection that primarily affects the lungs and can cause coughing, fever, and difficulty breathing.
10. Lung cancer: A type of cancer that originates in the lungs and can cause symptoms such as coughing, chest pain, and difficulty breathing.

These are just a few examples of respiration disorders, and there are many other conditions that can affect the respiratory system and cause breathing difficulties. If you are experiencing any symptoms of respiration disorders, it is important to seek medical attention to receive an accurate diagnosis and appropriate treatment.

Some common types of environmental illness include:

1. Asthma and other respiratory allergies: These conditions are caused by exposure to airborne pollutants such as dust, pollen, and smoke.
2. Chemical sensitivity: This condition is caused by exposure to chemicals in the environment, such as pesticides, solvents, and cleaning products.
3. Allergic contact dermatitis: This condition is caused by skin contact with allergens such as latex, metals, and certain plants.
4. Mold-related illnesses: Exposure to mold can cause a range of symptoms, including respiratory problems, skin irritation, and headaches.
5. Radon exposure: Radon is a radioactive gas that can accumulate in homes and buildings, particularly in basements and crawl spaces. Prolonged exposure to radon can increase the risk of lung cancer.
6. Carbon monoxide poisoning: This condition is caused by exposure to carbon monoxide, a colorless, odorless gas that can build up in enclosed spaces with faulty heating or cooking appliances.
7. Lead poisoning: Exposure to lead, particularly in children, can cause a range of health problems, including developmental delays, learning disabilities, and behavioral issues.
8. Mercury poisoning: Exposure to mercury, particularly through fish consumption, can cause neurological symptoms such as tremors, memory loss, and cognitive impairment.
9. Pesticide exposure: Exposure to pesticides, particularly organophosphates, can cause a range of health problems, including respiratory issues, skin irritation, and neurological symptoms.
10. Particulate matter exposure: Exposure to fine particulate matter (PM2.5) from air pollution can increase the risk of respiratory problems, cardiovascular disease, and cancer.

These are just a few examples of environmental health hazards that may be present in your home or building. It's important to be aware of these potential risks and take steps to mitigate them to ensure the health and safety of occupants.

Asthma can cause recurring episodes of wheezing, coughing, chest tightness, and shortness of breath. These symptoms occur when the muscles surrounding the airways contract, causing the airways to narrow and swell. This can be triggered by exposure to environmental allergens or irritants such as pollen, dust mites, pet dander, or respiratory infections.

There is no cure for asthma, but it can be managed with medication and lifestyle changes. Treatment typically includes inhaled corticosteroids to reduce inflammation, bronchodilators to open up the airways, and rescue medications to relieve symptoms during an asthma attack.

Asthma is a common condition that affects people of all ages, but it is most commonly diagnosed in children. According to the American Lung Association, more than 25 million Americans have asthma, and it is the third leading cause of hospitalization for children under the age of 18.

While there is no cure for asthma, early diagnosis and proper treatment can help manage symptoms and improve quality of life for those affected by the condition.

A blockage caused by air bubbles in the bloodstream, which can occur after a sudden change in atmospheric pressure (e.g., during an airplane flight or scuba diving). Air embolism can cause a variety of symptoms, including shortness of breath, chest pain, and stroke. It is a potentially life-threatening condition that requires prompt medical attention.

Note: Air embolism can also occur in the venous system, causing a pulmonary embolism (blockage of an artery in the lungs). This is a more common condition and is discussed separately.

Some common types of lung diseases include:

1. Asthma: A chronic condition characterized by inflammation and narrowing of the airways, leading to wheezing, coughing, and shortness of breath.
2. Chronic Obstructive Pulmonary Disease (COPD): A progressive condition that causes chronic inflammation and damage to the airways and lungs, making it difficult to breathe.
3. Pneumonia: An infection of the lungs that can be caused by bacteria, viruses, or fungi, leading to fever, chills, coughing, and difficulty breathing.
4. Bronchiectasis: A condition where the airways are damaged and widened, leading to chronic infections and inflammation.
5. Pulmonary Fibrosis: A condition where the lungs become scarred and stiff, making it difficult to breathe.
6. Lung Cancer: A malignant tumor that develops in the lungs, often caused by smoking or exposure to carcinogens.
7. Cystic Fibrosis: A genetic disorder that affects the respiratory and digestive systems, leading to chronic infections and inflammation in the lungs.
8. Tuberculosis (TB): An infectious disease caused by Mycobacterium Tuberculosis, which primarily affects the lungs but can also affect other parts of the body.
9. Pulmonary Embolism: A blockage in one of the arteries in the lungs, often caused by a blood clot that has traveled from another part of the body.
10. Sarcoidosis: An inflammatory disease that affects various organs in the body, including the lungs, leading to the formation of granulomas and scarring.

These are just a few examples of conditions that can affect the lungs and respiratory system. It's important to note that many of these conditions can be treated with medication, therapy, or surgery, but early detection is key to successful treatment outcomes.

1. Coronary artery disease: The narrowing or blockage of the coronary arteries, which supply blood to the heart.
2. Heart failure: A condition in which the heart is unable to pump enough blood to meet the body's needs.
3. Arrhythmias: Abnormal heart rhythms that can be too fast, too slow, or irregular.
4. Heart valve disease: Problems with the heart valves that control blood flow through the heart.
5. Heart muscle disease (cardiomyopathy): Disease of the heart muscle that can lead to heart failure.
6. Congenital heart disease: Defects in the heart's structure and function that are present at birth.
7. Peripheral artery disease: The narrowing or blockage of blood vessels that supply oxygen and nutrients to the arms, legs, and other organs.
8. Deep vein thrombosis (DVT): A blood clot that forms in a deep vein, usually in the leg.
9. Pulmonary embolism: A blockage in one of the arteries in the lungs, which can be caused by a blood clot or other debris.
10. Stroke: A condition in which there is a lack of oxygen to the brain due to a blockage or rupture of blood vessels.

Clinical Significance:
Respiratory sounds can help healthcare providers diagnose and manage respiratory conditions, such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. By listening to the sounds of a patient's breathing, healthcare providers can identify abnormalities in lung function, airway obstruction, or inflammation.

Types of Respiratory Sounds:

1. Vesicular Sounds:
a. Inspiratory wheeze: A high-pitched whistling sound heard during inspiration, usually indicative of bronchial asthma or COPD.
b. Expiratory wheeze: A low-pitched whistling sound heard during expiration, typically seen in patients with chronic bronchitis or emphysema.
c. Decreased vocal fremitus: A decrease in the normal vibratory sounds heard over the lung fields during breathing, which can indicate fluid or consolidation in the lungs.
2. Adventitious Sounds:
a. Crackles (rales): High-pitched, bubbly sounds heard during inspiration and expiration, indicating fluid or air in the alveoli.
b. Rhonchi: Low-pitched, harsh sounds heard during inspiration and expiration, often indicative of bronchitis, pneumonia, or COPD.
c. Stridors: High-pitched, squeaky sounds heard during breathing, commonly seen in patients with inflammatory conditions such as pneumonia or tuberculosis.

It's important to note that the interpretation of lung sounds requires a thorough understanding of respiratory physiology and pathophysiology, as well as clinical experience and expertise. A healthcare professional, such as a nurse or respiratory therapist, should always be consulted for an accurate diagnosis and treatment plan.

Otitis can be caused by a variety of factors, including bacterial or viral infections, allergies, and exposure to loud noises. Symptoms may include ear pain, fever, difficulty hearing, and discharge or fluid buildup in the ear canal.

There are several types of otitis, including:

1. Otitis externa: Inflammation of the outer ear canal, often caused by bacterial or fungal infections.
2. Otitis media: Inflammation of the middle ear, often caused by bacterial or viral infections.
3. Suppurative otitis media: A severe form of otitis media that is characterized by the formation of pus in the middle ear.
4. Tubotympanic otitis media: Inflammation of the middle ear and mastoid bone, often caused by bacterial or viral infections.
5. Otitis media with effusion: A condition in which fluid accumulates in the middle ear without signs of infection.

Treatment for otitis depends on the type and severity of the inflammation or infection, but may include antibiotics, ear drops, or other medications to relieve symptoms. In severe cases, surgery may be necessary to drain fluid or remove infected tissue.

Acute bronchitis is a short-term infection that is usually caused by a virus or bacteria, and can be treated with antibiotics and supportive care such as rest, hydration, and over-the-counter pain relievers. Chronic bronchitis, on the other hand, is a long-term condition that is often associated with smoking and can lead to chronic obstructive pulmonary disease (COPD).

Bronchitis can cause a range of symptoms including:

* Persistent cough, which may be dry or produce mucus
* Chest tightness or discomfort
* Shortness of breath or wheezing
* Fatigue and fever
* Headache and body aches

The diagnosis of bronchitis is usually made based on a physical examination, medical history, and results of diagnostic tests such as chest X-rays and pulmonary function tests. Treatment for bronchitis typically focuses on relieving symptoms and managing the underlying cause, such as a bacterial infection or smoking cessation.

Bronchitis can be caused by a variety of factors, including:

* Viral infections, such as the common cold or flu
* Bacterial infections, such as pneumonia
* Smoking and exposure to environmental pollutants
* Asthma and other allergic conditions
* Chronic lung diseases, such as COPD

Preventive measures for bronchitis include:

* Quitting smoking and avoiding exposure to secondhand smoke
* Getting vaccinated against flu and pneumonia
* Practicing good hygiene, such as washing hands frequently
* Avoiding exposure to environmental pollutants
* Managing underlying conditions such as asthma and allergies.

Premature birth can be classified into several categories based on gestational age at birth:

1. Extreme prematurity: Born before 24 weeks of gestation.
2. Very preterm: Born between 24-27 weeks of gestation.
3. Moderate to severe preterm: Born between 28-32 weeks of gestation.
4. Late preterm: Born between 34-36 weeks of gestation.

The causes of premature birth are not fully understood, but several factors have been identified as increasing the risk of premature birth. These include:

1. Previous premature birth
2. Multiple gestations (twins, triplets etc.)
3. History of cervical surgery or cervical incompetence
4. Chronic medical conditions such as hypertension and diabetes
5. Infections such as group B strep or urinary tract infections
6. Pregnancy-related complications such as preeclampsia and placenta previa
7. Stress and poor social support
8. Smoking, alcohol and drug use during pregnancy
9. Poor nutrition and lack of prenatal care.

Premature birth can have significant short-term and long-term health consequences for the baby, including respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, retinopathy of prematurity and necrotizing enterocolitis. Children who are born prematurely may also have developmental delays, learning disabilities and behavioral problems later in life.

There is no single test that can predict premature birth with certainty, but several screening tests are available to identify women at risk. These include ultrasound examination, maternal serum screening for estriol and pregnancy-associated plasma protein A (PAPP-A), and cervical length measurement.

While there is no proven way to prevent premature birth entirely, several strategies have been shown to reduce the risk, including:

1. Progesterone supplementation: Progesterone appears to help prevent preterm labor in some women with a history of previous preterm birth or other risk factors.
2. Corticosteroids: Corticosteroids given to mothers at risk of preterm birth can help mature the baby's lungs and reduce the risk of respiratory distress syndrome.
3. Calcium supplementation: Calcium may help improve fetal bone development and reduce the risk of premature birth.
4. Good prenatal care: Regular prenatal check-ups, proper nutrition and avoiding smoking, alcohol and drug use during pregnancy can help reduce the risk of premature birth.
5. Avoiding stress: Stress can increase the risk of premature birth, so finding ways to manage stress during pregnancy is important.
6. Preventing infections: Infections such as group B strep and urinary tract infections can increase the risk of premature birth, so it's important to take steps to prevent them.
7. Maintaining a healthy weight gain during pregnancy: Excessive weight gain during pregnancy can increase the risk of premature birth.
8. Avoiding preterm contractions: Preterm contractions can be a sign of impending preterm labor, so it's important to be aware of them and seek medical attention if they occur.
9. Prolonged gestation: Prolonging pregnancy beyond 37 weeks may reduce the risk of premature birth.
10. Cervical cerclage: A cervical cerclage is a stitch used to close the cervix and prevent preterm birth in women with a short cervix or other risk factors.

It's important to note that not all of these strategies will be appropriate or effective for every woman, so it's important to discuss your individual risk factors and any concerns you may have with your healthcare provider.
