Tuberculosis
Missed opportunities for prevention of tuberculosis among persons with HIV infection--selected locations, United States, 1996-1997. (1/72)
Public health contact investigations are conducted to find persons who have been exposed to patients with active tuberculosis (TB) and to evaluate and treat those contacts for TB infection and active TB. Persons in close (i.e., prolonged, frequent, or intense) contact with patients with active TB are at high risk for TB infection. The risk for TB infection is increased greatly if the close contact is infected with human immunodeficiency virus (HIV) (1,2). Isoniazid (INH) treatment for latent TB infection (LTBI) reduces the riskfor developing active TB by 41%-92% (1). This study examined the clinic records of TB programs to determine whether these programs used recommended practices to manage HIV-positive persons exposed to TB (3-8). The study suggests TB programs need to review their contact investigation policies, procedures, and outcomes to reduce missed opportunities for preventing active TB among HIV-positive close contacts. (+info)Effectiveness of postmigration screening in controlling tuberculosis among refugees: a historical cohort study, 1984-1998. (2/72)
OBJECTIVES: This study assessed the effectiveness of postmigration screening for the control of tuberculosis (TB) among refugee migrants. METHODS: We conducted a historical cohort study among 24 610 predominantly Southeast Asian refugees who had arrived in Sydney, Australia, between 1984 and 1994. All had been screened for TB before arrival and had radiologic follow-up for 18 months after arrival. Incident cases of TB were identified by record linkage analysis with confirmatory review of case notes. RESULTS: The crude annual incidence rate over 10-year follow-up was 74.9 per 100 000 person-years. Only 29.6% of the cases were diagnosed as a result of routine follow-up procedures. CONCLUSIONS: Enhanced passive case finding is likely to be more effective than active case finding for the control of TB among refugees. (+info)Tuberculosis screening among foreign-born persons applying for permanent US residence. (3/72)
OBJECTIVES: This study sought to determine adherence of physicians to tuberculosis (TB) screening guidelines among foreign-born persons living in the United States who were applying for permanent residency. METHODS: Medical forms of applicants from 5 geographic areas were reviewed, along with information from a national physician database on attending physicians. Applicant and corresponding physician characteristics were compared among those who were and were not correctly screened. RESULTS: Of 5739 applicants eligible for screening via tuberculin skin test, 75% were appropriately screened. Except in San Diego, where 11% of the applicants received no screening, most of the inappropriate screening resulted from the use of chest x-rays as the initial screening tool. CONCLUSIONS: Focused physician education and periodic monitoring of adherence to screening guidelines are warranted. (+info)Tuberculosis screening in the federal prison system: an opportunity to treat and prevent tuberculosis in foreign-born populations. (4/72)
OBJECTIVES: Despite recent success in tuberculosis (TB) control efforts in the United States, marked declines in TB case rates have not been observed in foreign-born populations. Because foreign-born populations are becoming more important for targeted national TB control efforts, the Federal Bureau of Prisons (BOP) reviewed inmate medical data to evaluate risk factors associated with Mycobacterium tuberculosis infection and active TB disease. To improve screening strategies, BOP implemented chest radiograph screening for all inmates entering a federal detention center in San Diego, California. METHODS: Tuberculin skin test (TST) data from an approximated intake cohort of inmates entering the system from February 1 to June 30, 1999, were analyzed to assess risk factors for M. tuberculosis infection among inmates entering federal prisons. The most recent case reports of inmates diagnosed with TB disease were reviewed. All inmates entering a San Diego detention facility from July 1 to December 31, 1998, were screened for TB by symptom review, TST, and chest radiographs. RESULTS: System-wide, foreign-born inmates were 5.9 times more likely to have a positive TST than US-born inmates, and accounted for 60% of recently diagnosed TB cases. Chest radiograph screening of all inmates entering the San Diego facility reduced exposure time to active TB cases by 75%, but TB incidence remained unchanged. CONCLUSIONS: The high prevalence of M. tuberculosis infection and TB disease among foreign-born inmates entering the federal prison system presents a strategic opportunity to provide preventive therapy to a high-risk population and to identify contagious cases that might elude traditional public health efforts. Universal chest radiograph screening was no more sensitive than TST for detecting active TB cases among newly incarcerated foreign-born inmates with a high prevalence of TB infection, but the screening reduced potential TB exposures through rapid identification of contagious cases. (+info)Longitudinal analyses of chest radiographs from the European Carbon Black Respiratory Morbidity Study. (5/72)
High levels of exposure to carbon black have been linked with an increased prevalence of chest radiograph abnormalities. However, it is unclear to what extent current levels of exposure in the carbon black manufacturing industry are associated with new cases of and progression in small opacities. Longitudinal analyses were carried out on data from workers in the European carbon black manufacturing industry who provided three full-size chest radiographs sequentially between 1987-1995. All chest radiographs were independently read by three experienced readers according to the International Labour Organisation (ILO) classification. After exclusion of participants with previous lung diseases or injuries, females, unreadable chest radiographs and from factories with a low participation rate, data from 675 workers were available for the longitudinal analyses. An association was observed between cumulative carbon black exposure and new cases of chest radiograph abnormalities (ILO category > or = 1/0) and progression in small opacities. These associations were mainly related to changes in chest radiographs from workers at one factory. A large percentage of workers with chest radiograph abnormalities reversed to normal chest films; however, after adjusting for other factors, this was not associated with levels of exposure to carbon black dust. In conclusion, the results show that exposure to carbon black is associated with increased risk of chest radiographic abnormalities, which may be reversible after reduction or cessation of exposure. (+info)Examining the effects of false positive lung cancer screening results on subsequent lung cancer screening adherence. (6/72)
OBJECTIVE: The study goal was to examine the effects of an initial false positive chest X-ray screening result on subsequent lung cancer screening adherence. METHODS: Adherence rates among 4705 individuals in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial at the Henry Ford Health System site with an abnormal/suspicious chest X-ray screening result in the first study year that was subsequently determined to be noncancerous (false positive result, n = 1137 exams) were compared with adherence rates among individuals with an initial negative chest X-ray screening result (n = 3568 exams). RESULTS: Univariate results showed a >50% increase in subsequent nonadherence among individuals with false positive screening results compared with those with negative screening results (17.2% versus 10.3% nonadherence rate, respectively; P < 0.001). Multivariable results showed that statistically significant predictors of nonadherence were false positive cases with current smoking status (P < 0.001) and false positive cases with past smoking status (P < 0.001). Additional predictors of subsequent nonadherence were being African-American (P < 0.01), being female (P < 0.001), and having a high school education or less (P < 0.01). CONCLUSION: Our results demonstrate that the impact of previous screening results, smoking status, race, gender, and education on subsequent screening adherence needs to be weighed carefully, particularly for smokers, an at-risk group, when conducting lung cancer screening intervention studies and perhaps should be considered in clinical practice as well. (+info)Pneumoconiosis prevalence among working coal miners examined in federal chest radiograph surveillance programs--United States, 1996-2002. (7/72)
Coal workers' pneumoconiosis (CWP) is a chronic lung disease caused by inhalation of coal mine dust. To characterize the prevalence of CWP, the National Institute for Occupational Safety and Health (NIOSH) analyzed recent radiographic information from the U.S. National Coal Workers' X-ray Surveillance Program (CWXSP). Established under the Federal Coal Mine Health and Safety Act of 1969, CWXSP is administered by NIOSH under federal regulations. NIOSH is responsible for approving coal miner examination plans, submitted approximately every 5 years by companies that operate underground coal mines. This report summarizes the results of the analysis, which indicate that the overall prevalence of CWP among participating miners continues to decline; however, new cases are occurring among miners who have worked exclusively under current dust exposure limits. An evaluation of the mining conditions that have resulted in these cases is underway. (+info)PUVALLUTTUQ: AN EPIDEMIC OF TUBERCULOSIS AT ESKIMO POINT, NORTHWEST TERRITORIES. (8/72)
An explosive epidemic of tuberculosis in a small isolated settlement is described. This outbreak, in a population of 329 Eskimos and 16 whites, produced 80 cases of active tuberculosis, involving 55% of all the house-holds. Forty-five of these patients were children under 10 years of age and only five were persons over 30. These patients probably were infected by one highly infectious individual.The contributing causes of poor housing, overcrowding and poor nutrition, coupled with the debilitating effect of recent epidemics of virus diseases, measles, mumps and German measles, are discussed.Since this article was written, a third resurvey in the same year, conducted in November 1963, revealed 11 more cases among the 279 members of the population who underwent radiological examination; all are hospitalized. (+info)A "mass chest X-ray" is a term used to describe a radiological screening procedure where a large number of individuals undergo chest X-rays, usually as part of a public health campaign or community screening event. The goal is to identify any early signs of lung diseases such as tuberculosis, lung cancer, or other pulmonary abnormalities. It's important to note that while mass screenings can help detect diseases at an earlier stage, they also raise concerns about radiation exposure and the potential for overdiagnosis. Therefore, such procedures are typically carried out under strict medical guidelines and regulations.
Pneumoconiosis is a group of lung diseases caused by inhaling dust particles, leading to fibrosis or scarring of the lungs. The type of pneumoconiosis depends on the specific dust inhaled. Examples include coal worker's pneumoconiosis (from coal dust), silicosis (from crystalline silica dust), and asbestosis (from asbestos fibers). These diseases are generally preventable by minimizing exposure to harmful dusts through proper engineering controls, protective equipment, and workplace safety regulations.
Occupational diseases are health conditions or illnesses that occur as a result of exposure to hazards in the workplace. These hazards can include physical, chemical, and biological agents, as well as ergonomic factors and work-related psychosocial stressors. Examples of occupational diseases include respiratory illnesses caused by inhaling dust or fumes, hearing loss due to excessive noise exposure, and musculoskeletal disorders caused by repetitive movements or poor ergonomics. The development of an occupational disease is typically related to the nature of the work being performed and the conditions in which it is carried out. It's important to note that these diseases can be prevented or minimized through proper risk assessment, implementation of control measures, and adherence to safety regulations.
A lung is a pair of spongy, elastic organs in the chest that work together to enable breathing. They are responsible for taking in oxygen and expelling carbon dioxide through the process of respiration. The left lung has two lobes, while the right lung has three lobes. The lungs are protected by the ribcage and are covered by a double-layered membrane called the pleura. The trachea divides into two bronchi, which further divide into smaller bronchioles, leading to millions of tiny air sacs called alveoli, where the exchange of gases occurs.
Chest pain is a discomfort or pain that you feel in the chest area. The pain can be sharp, dull, burning, crushing, heaviness, or tightness. It may be accompanied by other symptoms such as shortness of breath, sweating, nausea, dizziness, or pain that radiates to the arm, neck, jaw, or back.
Chest pain can have many possible causes, including heart-related conditions such as angina or a heart attack, lung conditions such as pneumonia or pleurisy, gastrointestinal problems such as acid reflux or gastritis, musculoskeletal issues such as costochondritis or muscle strain, and anxiety or panic attacks.
It is important to seek immediate medical attention if you experience chest pain that is severe, persistent, or accompanied by other concerning symptoms, as it may be a sign of a serious medical condition. A healthcare professional can evaluate your symptoms, perform tests, and provide appropriate treatment.
Chest tubes are medical devices that are inserted into the chest cavity to drain fluid, air, or blood. They are typically used to treat conditions such as pneumothorax (collapsed lung), hemothorax (blood in the chest cavity), pleural effusion (excess fluid in the chest cavity), and chylothorax (milky fluid in the chest cavity).
Chest tubes are usually inserted between the ribs and directed into the chest cavity, allowing for drainage of the affected area. The tubes are connected to a collection system that creates negative pressure, which helps to remove the air or fluid from the chest cavity.
The size and number of chest tubes used may vary depending on the severity and location of the condition being treated. Chest tubes are typically removed once the underlying condition has been resolved and the drainage has decreased to a minimal amount.
Gamma rays are a type of ionizing radiation that is released from the nucleus of an atom during radioactive decay. They are high-energy photons, with wavelengths shorter than 0.01 nanometers and frequencies greater than 3 x 10^19 Hz. Gamma rays are electromagnetic radiation, similar to X-rays, but with higher energy levels and the ability to penetrate matter more deeply. They can cause damage to living tissue and are used in medical imaging and cancer treatment.
Mass spectrometry (MS) is an analytical technique used to identify and quantify the chemical components of a mixture or compound. It works by ionizing the sample, generating charged molecules or fragments, and then measuring their mass-to-charge ratio in a vacuum. The resulting mass spectrum provides information about the molecular weight and structure of the analytes, allowing for identification and characterization.
In simpler terms, mass spectrometry is a method used to determine what chemicals are present in a sample and in what quantities, by converting the chemicals into ions, measuring their masses, and generating a spectrum that shows the relative abundances of each ion type.
Radiography is a diagnostic technique that uses X-rays, gamma rays, or similar types of radiation to produce images of the internal structures of the body. It is a non-invasive procedure that can help healthcare professionals diagnose and monitor a wide range of medical conditions, including bone fractures, tumors, infections, and foreign objects lodged in the body.
During a radiography exam, a patient is positioned between an X-ray machine and a special film or digital detector. The machine emits a beam of radiation that passes through the body and strikes the film or detector, creating a shadow image of the internal structures. Denser tissues, such as bones, block more of the radiation and appear white on the image, while less dense tissues, such as muscles and organs, allow more of the radiation to pass through and appear darker.
Radiography is a valuable tool in modern medicine, but it does involve exposure to ionizing radiation, which can carry some risks. Healthcare professionals take steps to minimize these risks by using the lowest possible dose of radiation necessary to produce a diagnostic image, and by shielding sensitive areas of the body with lead aprons or other protective devices.
Thoracic radiography is a type of diagnostic imaging that involves using X-rays to produce images of the chest, including the lungs, heart, bronchi, great vessels, and the bones of the spine and chest wall. It is a commonly used tool in the diagnosis and management of various respiratory, cardiovascular, and thoracic disorders such as pneumonia, lung cancer, heart failure, and rib fractures.
During the procedure, the patient is positioned between an X-ray machine and a cassette containing a film or digital detector. The X-ray beam is directed at the chest, and the resulting image is captured on the film or detector. The images produced can help identify any abnormalities in the structure or function of the organs within the chest.
Thoracic radiography may be performed as a routine screening test for certain conditions, such as lung cancer, or it may be ordered when a patient presents with symptoms suggestive of a respiratory or cardiovascular disorder. It is a safe and non-invasive procedure that can provide valuable information to help guide clinical decision making and improve patient outcomes.
The thoracic wall refers to the anatomical structure that surrounds and protects the chest cavity or thorax, which contains the lungs, heart, and other vital organs. It is composed of several components:
1. Skeletal framework: This includes the 12 pairs of ribs, the sternum (breastbone) in the front, and the thoracic vertebrae in the back. The upper seven pairs of ribs are directly attached to the sternum in the front through costal cartilages. The lower five pairs of ribs are not directly connected to the sternum but are joined to the ribs above them.
2. Muscles: The thoracic wall contains several muscles, including the intercostal muscles (located between the ribs), the scalene muscles (at the side and back of the neck), and the serratus anterior muscle (on the sides of the chest). These muscles help in breathing by expanding and contracting the ribcage.
3. Soft tissues: The thoracic wall also contains various soft tissues, such as fascia, nerves, blood vessels, and fat. These structures support the functioning of the thoracic organs and contribute to the overall stability and protection of the chest cavity.
The primary function of the thoracic wall is to protect the vital organs within the chest cavity while allowing for adequate movement during respiration. Additionally, it provides a stable base for the attachment of various muscles involved in upper limb movement and posture.
Electron Probe Microanalysis (EPMA) is a technique used in materials science and geology to analyze the chemical composition of materials at very small scales, typically on the order of microns or less. In this technique, a focused beam of electrons is directed at a sample, causing the emission of X-rays that are characteristic of the elements present in the sample. By analyzing the energy and intensity of these X-rays, researchers can determine the concentration of different elements in the sample with high precision and accuracy.
EPMA is typically performed using a specialized instrument called an electron probe microanalyzer (EPMA), which consists of an electron column for generating and focusing the electron beam, an X-ray spectrometer for analyzing the emitted X-rays, and a stage for positioning and manipulating the sample. The technique is widely used in fields such as mineralogy, geochemistry, metallurgy, and materials science to study the composition and structure of minerals, alloys, semiconductors, and other materials.
One of the key advantages of EPMA is its ability to analyze the chemical composition of small regions within a sample, even in cases where there are spatial variations in composition or where the sample is heterogeneous. This makes it an ideal technique for studying the distribution and behavior of trace elements in minerals, the microstructure of alloys and other materials, and the composition of individual grains or phases within a polyphase material. Additionally, EPMA can be used to analyze both conductive and non-conductive samples, making it a versatile tool for a wide range of applications.
Body Mass Index (BMI) is a measure used to assess whether a person has a healthy weight for their height. It's calculated by dividing a person's weight in kilograms by the square of their height in meters. Here is the medical definition:
Body Mass Index (BMI) = weight(kg) / [height(m)]^2
According to the World Health Organization, BMI categories are defined as follows:
* Less than 18.5: Underweight
* 18.5-24.9: Normal or healthy weight
* 25.0-29.9: Overweight
* 30.0 and above: Obese
It is important to note that while BMI can be a useful tool for identifying weight issues in populations, it does have limitations when applied to individuals. For example, it may not accurately reflect body fat distribution or muscle mass, which can affect health risks associated with excess weight. Therefore, BMI should be used as one of several factors when evaluating an individual's health status and risk for chronic diseases.
'Elasmobranchii' is a superorder in the class Chondrichthyes, which includes all sharks, skates, rays, and sawfishes. This group is characterized by several distinct features, including:
1. Cartilaginous skeletons: Unlike bony fishes, elasmobranchs have skeletons made of cartilage rather than bone.
2. Five to seven gill slits: Most elasmobranchs have five pairs of gill slits on each side of their body, although some species may have six or seven pairs. These gill slits are open to the outside environment and lack protective covers found in bony fishes.
3. Heterocercal tail: Elasmobranchs possess a unique tail structure called a heterocercal tail, where the upper lobe is longer than the lower lobe. This tail design provides powerful propulsion and maneuverability in the water.
4. Dermal denticles: The skin of elasmobranchs is covered with small, tooth-like structures called dermal denticles, which provide a protective covering and reduce friction while swimming.
5. No swim bladders: Unlike bony fishes, elasmobranchs do not have a gas-filled swim bladder to help maintain buoyancy. Instead, they rely on their large liver, which contains low-density oil, to provide some degree of buoyancy.
6. Electrosensory organs: Many elasmobranchs possess specialized sensory organs called the ampullae of Lorenzini, which allow them to detect electric fields generated by living organisms and other environmental sources. This ability aids in hunting, navigation, and communication.
7. Carnivorous diet: Elasmobranchs are primarily carnivorous, feeding on various marine animals such as fish, squid, and crustaceans. Some species may also consume smaller elasmobranchs.
8. Live birth or egg laying: Most elasmobranchs reproduce by giving live birth (viviparity), where the embryos develop inside the mother's body and receive nourishment through a placenta-like structure. However, some species lay eggs (oviparity) in protective cases called mermaid's purses.
9. Slow growth and late maturity: Elasmobranchs generally grow slowly and reach sexual maturity at a relatively advanced age compared to many bony fishes. This slow life history makes them particularly vulnerable to overfishing and other human-induced threats.
The thorax is the central part of the human body, located between the neck and the abdomen. In medical terms, it refers to the portion of the body that contains the heart, lungs, and associated structures within a protective cage made up of the sternum (breastbone), ribs, and thoracic vertebrae. The thorax is enclosed by muscles and protected by the ribcage, which helps to maintain its structural integrity and protect the vital organs contained within it.
The thorax plays a crucial role in respiration, as it allows for the expansion and contraction of the lungs during breathing. This movement is facilitated by the flexible nature of the ribcage, which expands and contracts with each breath, allowing air to enter and exit the lungs. Additionally, the thorax serves as a conduit for major blood vessels, such as the aorta and vena cava, which carry blood to and from the heart and the rest of the body.
Understanding the anatomy and function of the thorax is essential for medical professionals, as many conditions and diseases can affect this region of the body. These may include respiratory disorders such as pneumonia or chronic obstructive pulmonary disease (COPD), cardiovascular conditions like heart attacks or aortic aneurysms, and musculoskeletal issues involving the ribs, spine, or surrounding muscles.
Flail chest is a serious injury to the thorax characterized by a segment of the chest wall that moves paradoxically in relation to the rest of the chest wall during respiration. This occurs due to multiple rib fractures at two or more places, resulting in a free-floating section of the chest wall that is not connected to the sternum or spine.
During inspiration, when the chest normally expands, the flail segment moves inward, and during expiration, it moves outward, which can lead to significant impairment of ventilation and oxygenation. Flail chest can result from high-impact trauma such as motor vehicle accidents or falls, and it is often associated with underlying lung contusions or other injuries. It requires immediate medical attention and may necessitate mechanical ventilation and surgical stabilization of the rib cage to prevent complications such as pneumonia and respiratory failure.
Thoracic injuries refer to damages or traumas that occur in the thorax, which is the part of the body that contains the chest cavity. The thorax houses vital organs such as the heart, lungs, esophagus, trachea, and major blood vessels. Thoracic injuries can range from blunt trauma, caused by impacts or compressions, to penetrating trauma, resulting from stabbing or gunshot wounds. These injuries may cause various complications, including but not limited to:
1. Hemothorax - bleeding into the chest cavity
2. Pneumothorax - collapsed lung due to air accumulation in the chest cavity
3. Tension pneumothorax - a life-threatening condition where trapped air puts pressure on the heart and lungs, impairing their function
4. Cardiac tamponade - compression of the heart caused by blood or fluid accumulation in the pericardial sac
5. Rib fractures, which can lead to complications like punctured lungs or internal bleeding
6. Tracheobronchial injuries, causing air leaks and difficulty breathing
7. Great vessel injuries, potentially leading to massive hemorrhage and hemodynamic instability
Immediate medical attention is required for thoracic injuries, as they can quickly become life-threatening due to the vital organs involved. Treatment may include surgery, chest tubes, medications, or supportive care, depending on the severity and type of injury.
X-ray computed tomography (CT or CAT scan) is a medical imaging method that uses computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of the body. These cross-sectional images can then be used to display detailed internal views of organs, bones, and soft tissues in the body.
The term "computed tomography" is used instead of "CT scan" or "CAT scan" because the machines take a series of X-ray measurements from different angles around the body and then use a computer to process these data to create detailed images of internal structures within the body.
CT scanning is a noninvasive, painless medical test that helps physicians diagnose and treat medical conditions. CT imaging provides detailed information about many types of tissue including lung, bone, soft tissue and blood vessels. CT examinations can be performed on every part of the body for a variety of reasons including diagnosis, surgical planning, and monitoring of therapeutic responses.
In computed tomography (CT), an X-ray source and detector rotate around the patient, measuring the X-ray attenuation at many different angles. A computer uses this data to construct a cross-sectional image by the process of reconstruction. This technique is called "tomography". The term "computed" refers to the use of a computer to reconstruct the images.
CT has become an important tool in medical imaging and diagnosis, allowing radiologists and other physicians to view detailed internal images of the body. It can help identify many different medical conditions including cancer, heart disease, lung nodules, liver tumors, and internal injuries from trauma. CT is also commonly used for guiding biopsies and other minimally invasive procedures.
In summary, X-ray computed tomography (CT or CAT scan) is a medical imaging technique that uses computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional images of the body. It provides detailed internal views of organs, bones, and soft tissues in the body, allowing physicians to diagnose and treat medical conditions.
"Fast neutrons" are defined in the field of medical physics and nuclear medicine as neutrons that have high kinetic energy, typically greater than 1 MeV (mega-electron volts). These high-energy neutrons can cause ionization and damage to tissues and cells when they interact with matter, including biological tissue. They are produced in various nuclear reactions, such as those occurring in the core of a nuclear reactor or in the detonation of a nuclear weapon. In medical contexts, fast neutrons may be used in radiation therapy for cancer treatment, where they can deposit their energy directly into tumors and cause DNA damage that leads to cell death.
A Radiology Department in a hospital is a specialized unit where diagnostic and therapeutic imaging examinations are performed using various forms of radiant energy, including X-rays, magnetic fields, ultrasound, and radio waves. The department is staffed by radiologists (physicians who specialize in the interpretation of medical images) and radiologic technologists who operate the imaging equipment.
The Radiology Department provides a range of services, such as:
1. Diagnostic Radiology: Uses various imaging techniques to diagnose and monitor diseases and injuries, including X-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and mammography.
2. Interventional Radiology: Utilizes image guidance to perform minimally invasive procedures, such as biopsies, tumor ablations, and angioplasty.
3. Nuclear Medicine: Uses small amounts of radioactive materials to diagnose and treat diseases, including bone scans, thyroid studies, and positron emission tomography (PET) scans.
4. Radiation Therapy: Treats cancer using high-energy radiation beams targeted at tumors to destroy cancer cells while minimizing damage to surrounding healthy tissue.
The primary goal of the Radiology Department is to provide accurate and timely diagnostic information, support clinical decision-making, and contribute to improved patient outcomes through effective imaging services.
Mass spectrometry with electrospray ionization (ESI-MS) is an analytical technique used to identify and quantify chemical species in a sample based on the mass-to-charge ratio of charged particles. In ESI-MS, analytes are ionized through the use of an electrospray, where a liquid sample is introduced through a metal capillary needle at high voltage, creating an aerosol of charged droplets. As the solvent evaporates, the analyte molecules become charged and can be directed into a mass spectrometer for analysis.
ESI-MS is particularly useful for the analysis of large biomolecules such as proteins, peptides, and nucleic acids, due to its ability to gently ionize these species without fragmentation. The technique provides information about the molecular weight and charge state of the analytes, which can be used to infer their identity and structure. Additionally, ESI-MS can be interfaced with separation techniques such as liquid chromatography (LC) for further purification and characterization of complex samples.
Thoracic neoplasms refer to abnormal growths or tumors that develop in the thorax, which is the area of the body that includes the chest and lungs. These neoplasms can be benign (non-cancerous) or malignant (cancerous). Malignant thoracic neoplasms are often referred to as lung cancer, but they can also include other types of cancer such as mesothelioma, thymoma, and esophageal cancer.
Thoracic neoplasms can cause various symptoms depending on their location and size. Common symptoms include coughing, chest pain, shortness of breath, hoarseness, and difficulty swallowing. Treatment options for thoracic neoplasms depend on the type, stage, and location of the tumor, as well as the patient's overall health. Treatment may include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these approaches.
Tandem mass spectrometry (MS/MS) is a technique used to identify and quantify specific molecules, such as proteins or metabolites, within complex mixtures. This method uses two or more sequential mass analyzers to first separate ions based on their mass-to-charge ratio and then further fragment the selected ions into smaller pieces for additional analysis. The fragmentation patterns generated in MS/MS experiments can be used to determine the structure and identity of the original molecule, making it a powerful tool in various fields such as proteomics, metabolomics, and forensic science.
Radiation dosage, in the context of medical physics, refers to the amount of radiation energy that is absorbed by a material or tissue, usually measured in units of Gray (Gy), where 1 Gy equals an absorption of 1 Joule of radiation energy per kilogram of matter. In the clinical setting, radiation dosage is used to plan and assess the amount of radiation delivered to a patient during treatments such as radiotherapy. It's important to note that the biological impact of radiation also depends on other factors, including the type and energy level of the radiation, as well as the sensitivity of the irradiated tissues or organs.
The pleura is the medical term for the double-layered serous membrane that surrounds the lungs and lines the inside of the chest cavity. The two layers of the pleura are called the parietal pleura, which lines the chest cavity, and the visceral pleura, which covers the surface of the lungs.
The space between these two layers is called the pleural cavity, which contains a small amount of lubricating fluid that allows the lungs to move smoothly within the chest during breathing. The main function of the pleura is to protect the lungs and facilitate their movement during respiration.
The wrist joint, also known as the radiocarpal joint, is a condyloid joint that connects the distal end of the radius bone in the forearm to the proximal row of carpal bones in the hand (scaphoid, lunate, and triquetral bones). It allows for flexion, extension, radial deviation, and ulnar deviation movements of the hand. The wrist joint is surrounded by a capsule and reinforced by several ligaments that provide stability and strength to the joint.
Photofluorography is not a widely used medical term, but it generally refers to a radiographic technique that uses fluorescent screens to produce images. It was historically used for mass screening of pulmonary diseases such as tuberculosis. The patient would be exposed to a low-dose X-ray, and the resulting image would be captured on a special film or sensor that is sensitive to light emitted by the fluorescent screen.
However, it's worth noting that photofluorography has largely been replaced by digital radiography and other modern imaging techniques in clinical practice.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
I believe there may be a slight misunderstanding in your question. "Inventors" are typically not a term used in the medical field to describe a condition or diagnosis. An inventor is an individual who creates or designs a new device, method, process, or product, through the use of creativity and innovation.
If you meant to ask for a medical definition of a different term, please let me know and I would be happy to help.
Fluoroscopy is a type of medical imaging that uses X-rays to obtain real-time moving images of the internal structures of the body. A continuous X-ray beam is passed through the body part being examined, and the resulting fluoroscopic images are transmitted to a monitor, allowing the medical professional to view the structure and movement of the internal organs and bones in real time.
Fluoroscopy is often used to guide minimally invasive procedures such as catheterization, stent placement, or joint injections. It can also be used to diagnose and monitor a variety of medical conditions, including gastrointestinal disorders, musculoskeletal injuries, and cardiovascular diseases.
It is important to note that fluoroscopy involves exposure to ionizing radiation, and the risks associated with this exposure should be carefully weighed against the benefits of the procedure. Medical professionals are trained to use the lowest possible dose of radiation necessary to obtain the desired diagnostic information.
Pulmonary medicine is a medical specialty that deals with the diagnosis, treatment, and prevention of diseases and conditions affecting the respiratory system, including the lungs, trachea, bronchi, bronchioles, and alveoli. Pulmonologists are specialists who treat a wide range of respiratory disorders such as chronic obstructive pulmonary disease (COPD), asthma, bronchitis, pneumonia, lung cancer, sleep-disordered breathing, tuberculosis, and interstitial lung diseases. They use various diagnostic techniques including chest X-rays, CT scans, pulmonary function tests, bronchoscopy, and sleep studies to evaluate and manage respiratory disorders. Pulmonologists also provide care for patients who require long-term mechanical ventilation or oxygen therapy.
Tuberculosis (TB) is a chronic infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also involve other organs and tissues in the body. The infection is usually spread through the air when an infected person coughs, sneezes, or talks.
The symptoms of pulmonary TB include persistent cough, chest pain, coughing up blood, fatigue, fever, night sweats, and weight loss. Diagnosis typically involves a combination of medical history, physical examination, chest X-ray, and microbiological tests such as sputum smear microscopy and culture. In some cases, molecular tests like polymerase chain reaction (PCR) may be used for rapid diagnosis.
Treatment usually consists of a standard six-month course of multiple antibiotics, including isoniazid, rifampin, ethambutol, and pyrazinamide. In some cases, longer treatment durations or different drug regimens might be necessary due to drug resistance or other factors. Preventive measures include vaccination with the Bacillus Calmette-Guérin (BCG) vaccine and early detection and treatment of infected individuals to prevent transmission.
Interventional Magnetic Resonance Imaging (MRI) is a medical imaging technique that combines the diagnostic capabilities of MRI with minimally invasive image-guided procedures. It uses a strong magnetic field, radio waves, and computer software to produce detailed images of the body's internal structures and soft tissues.
In interventional MRI, the technology is used in real-time to guide the placement of needles, catheters, or other medical instruments for diagnostic or therapeutic purposes. This can include biopsies, tumor ablations, or targeted drug deliveries. The primary advantage of interventional MRI over traditional interventional radiology techniques is its ability to provide high-resolution imaging without the use of radiation, making it a safer option for certain patients. However, it requires specialized equipment and trained personnel to perform these procedures.
