Acute knee joint rupture after yttrium 90 injection. (1/11)
Two cases of acute rupture of the knee joint are reported after the intra-articular injection of radioactive yttrium 90. It is suggested that this may be a complication of intra-articular radioactive injections. (+info)Biologic and immunologic therapies for ovarian cancer. (2/11)
Biologic therapy of ovarian cancer has been conducted using nonspecific biologic response modifiers, cytokines, monoclonal antibodies (MAbs), vaccines, and gene therapy. Antibodies directed toward her2/neu have also been studied. Phase I and II gene therapy trials using adenoviral vectors containing a wild-type or modified p53 have shown that the treatment is well tolerated. Phase II and III trials are ongoing with MAbs directed against CA-125 (MAb B43.13) and an antibody directed against HMFG1 (anti-HMFG1-yttrium-90-labeled antibody). The trials have shown that these agents are well tolerated and that immunologic responses occur, although the ultimate clinical value of these agents remains to be determined. Prolonged survival after MAb B43.13 treatment has been correlated with changes in several immune parameters, including human antimurine antibody, Ab2, anti-CA-125 antibody development, and induced T-cell immunity. Clinical trials using a MAb directed toward the encoded products of her2/neu have shown minimal activity against ovarian cancer in a phase I and II trial conducted by the Gynecologic Oncology Group. Cytokine therapies have been administered systemically and intraperitoneally. Intracavitary interferon alfa, interferon gamma, and interleukin-2 alone or in combination with cytotoxic therapy in phase I and II trials demonstrated intraperitoneal lymphoid cell stimulation and produced antitumor responses. A randomized trial of chemotherapy with or without interferon gamma in primary treatment produced a response and a progression-free survival advantage in the arm that incorporated the interferon gamma, without a statistically significant benefit in overall survival. A phase III study of interferon gamma in combination with first-line chemotherapy is currently ongoing.

(+info)Quantitative comparison of yttrium-90 (90Y)-microspheres and technetium-99m (99mTc)-macroaggregated albumin SPECT images for planning 90Y therapy of liver cancer. (5/11)
Yttrium-90 ((90)Y)-microspheres administered via the hepatic artery has been used for the treatment of unresectable primary or metastatic cancer in the liver. Prior to (90)Y therapy, however, the (90)Y administered activity and the percent shunting to lungs must be determined, most commonly by gamma camera imaging of technetium-99m ((99m)Tc)-macroaggregated albumin (MAA). The purpose of the current study was to identify and evaluate an objective measure of the correlation of (90)Y and MAA activity distributions and thus assess the reliability of MAA imaging for evaluation of (90)Y administered activity and tumor and liver radiation doses. The MAA study consisted of two acquisitions. After administration of 185 MBq of MAA, a partial-body or so-called breakthrough scan was performed in order to determine the percent shunting to lungs. Immediately after a breakthrough scan, a combined single-photon emission computed tomography (SPECT)/transmission computed tomography (CT) scanner was used to image MAA distribution in order to derived the prescribed (90)Y administered activity based on tumor and liver dosimetry. (90)Y SPECT/CT was performed 2-4 weeks later and activities used were in the range of 777-2,442 MBq. In order to compare (90)Y and MAA SPECT images, first the respective CT image sets were registered using a transform based on normalized mutual information. The transform thus derived was used to align the 90Y and MAA SPECT image sets, and the Spearman's (rho) rank correlation as well as image distance (L2-norm) between the registered SPECT images were then calculated. The Spearman's rank correlation values ranged from 0.451 to 0.818 and the L2 distances from 0.626 to 2.889. Based on visual inspection, the registration of the (90)Y and MAA SPECT images appeared reasonably accurate. The regression coefficient (r) between visual scoring and the Spearman's rank correlation was 0.65 and between visual scoring and L2 distance 0.61. The Spearman's rank correlation thus appears to be more reliable than the image distance for assessing the correlation of the (90)Y and MAA images.

(+info)Histochemical phosphatases and metachromasia in murine tumours induced by bone seeking radionuclides. (7/11)
Tumours induced in mice, either CBA normal and chimaerical, or C3H, by (90)Sr or (226)Ra or plutonium have been examined histochemically with (1) diazotate fast red violet LB salt in naphthol AS-MX phosphate buffer at pH 8.6 and 5.2, (2) 1: 9 dimethyl methylene blue (Taylor).It is concluded:(a) The diagnosis of osteosarcoma is facilitated with Taylor's Blue which stains osteoid metachromatically. Cells of osteosarcoma, like normal osteoblasts, contain alkaline phosphatase but this may be lost by mutation either in the original tumour or subsequently on passage of the tumour serially to compatible hosts.(b) Osteosarcomata may contain giant-cells of two forms, bizarre tumour cells and osteoclasts; the latter contain acid phosphatase. Osteosarcomata which retain their osteoid on serial passage have few cells containing acid phosphatases.(c) Primitive mesenchymal cell tumours of angiomatous form may occur, if the bone marrow is irradiated, e.g. by (90)Sr-(90)Y and Pu. These tumours lack osteoid and cells interpretable as osteoblasts or osteoclasts (though they destroy bone).(d) Tumours classifiable as fibrosarcomata occur rarely, and may be truly of fibroblastic origin or be mutated osteosarcomata.(e) Lymphomata also occur when the marrow is irradiated ((90)Sr-(90)Y and Pu). They may be generalized, when their cells may contain alkaline phosphatase or lack it. They may be localized to abdominal viscera, the reticulo-sarcomatous form, in which case the cells lack alkaline phosphatase. (+info)Sebum excretion in acromegaly. (8/11)
The sebum excretion rate (S.E.R.) was measured in 20 patients with acromegaly. Eleven were untreated at the time of the measurement and nine had previously undergone surgical hypophysectomy or had received pituitary irradiation by yttrium-90 or radiotherapy. In five patients the S.E.R. was measured before and after such treatment. The mean S.E.R. in the untreated acromegalics was much greater than in a normal population and decreased significantly after successful pituitary ablation. No significant decrease in mean S.E.R. occurred in the group of patients with a poor clinical response to ablation. The correlations between S.E.R. and log serum growth hormone, plasma 11-hydroxycorticosteroid levels, and heel-pad thickness were significant, but there was no significant correlation between S.E.R. and serum protein-bound iodine levels. This suggests that the changes in S.E.R. were due to pituitary ablation but could not necessarily be attributed solely to changes in growth hormone, thyroid-stimulating hormone, or adrenocorticotrophic hormone. The association between the clinical state of the acromegaly and the S.E.R. was better than the association between acromegaly and serum growth hormone. We conclude that the S.E.R. is a useful addition to the clinical and endocrinological data used in assessing acromegaly. (+info)Yttrium isotopes are different forms of the element yttrium, which have the same number of protons in their atomic nuclei (which is 39 and defines the element), but different numbers of neutrons. This results in a difference in the mass number of the isotopes. For example, the most common yttrium isotope is Y-89, which has 39 protons and 50 neutrons, giving it a mass number of 89. However, there are also other yttrium isotopes such as Y-88, Y-90, Y-91 etc., with different numbers of neutrons and thus different mass numbers. Some yttrium isotopes are stable, while others are unstable and radioactive, meaning they will decay into other elements over time.
Yttrium is not a medical term itself, but it is a chemical element with the symbol "Y" and atomic number 39. It is a silvery-metallic transition element that is found in rare earth minerals.
In the field of medicine, yttrium is used in the production of some medical devices and treatments. For example, yttrium-90 is a radioactive isotope that is used in the treatment of certain types of cancer, such as liver cancer and lymphoma. Yttrium-90 is often combined with other substances to form tiny beads or particles that can be injected directly into tumors, where they release radiation that helps to destroy cancer cells.
Yttrium aluminum garnet (YAG) lasers are also used in medical procedures such as eye surgery and dental work. These lasers emit a highly concentrated beam of light that can be used to cut or coagulate tissue with great precision.
Overall, while yttrium is not a medical term itself, it does have important applications in the field of medicine.
Yttrium radioisotopes are radioactive isotopes or variants of the element Yttrium, which is a rare earth metal. These radioisotopes are artificially produced and have unstable nuclei that emit radiation in the form of gamma rays or high-speed particles. Examples of yttrium radioisotopes include Yttrium-90 and Yttrium-86, which are used in medical applications such as radiotherapy for cancer treatment and molecular imaging for diagnostic purposes.
Yttrium-90 is a pure beta emitter with a half-life of 64.1 hours, making it useful for targeted radionuclide therapy. It can be used to treat liver tumors, leukemia, and lymphoma by attaching it to monoclonal antibodies or other targeting agents that selectively bind to cancer cells.
Yttrium-86 is a positron emitter with a half-life of 14.7 hours, making it useful for positron emission tomography (PET) imaging. It can be used to label radiopharmaceuticals and track their distribution in the body, providing information on the location and extent of disease.
It is important to note that handling and use of radioisotopes require specialized training and equipment due to their potential radiation hazards.
Isotopes are variants of a chemical element that have the same number of protons in their atomic nucleus, but a different number of neutrons. This means they have different atomic masses, but share similar chemical properties. Some isotopes are stable and do not decay naturally, while others are unstable and radioactive, undergoing radioactive decay and emitting radiation in the process. These radioisotopes are often used in medical imaging and treatment procedures.
Isotope labeling is a scientific technique used in the field of medicine, particularly in molecular biology, chemistry, and pharmacology. It involves replacing one or more atoms in a molecule with a radioactive or stable isotope of the same element. This modified molecule can then be traced and analyzed to study its structure, function, metabolism, or interaction with other molecules within biological systems.
Radioisotope labeling uses unstable radioactive isotopes that emit radiation, allowing for detection and quantification of the labeled molecule using various imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT). This approach is particularly useful in tracking the distribution and metabolism of drugs, hormones, or other biomolecules in living organisms.
Stable isotope labeling, on the other hand, employs non-radioactive isotopes that do not emit radiation. These isotopes have different atomic masses compared to their natural counterparts and can be detected using mass spectrometry. Stable isotope labeling is often used in metabolic studies, protein turnover analysis, or for identifying the origin of specific molecules within complex biological samples.
In summary, isotope labeling is a versatile tool in medical research that enables researchers to investigate various aspects of molecular behavior and interactions within biological systems.
I'm sorry for any confusion, but "Neodymium" is not a medical term. It is a chemical element with the symbol Nd and atomic number 60. Neodymium is a rare-earth metal that has been used in various industrial and technological applications, such as magnets, lasers, and glass coloration. It is not directly related to medical terminology or healthcare.
Solid-state lasers are a type of laser that uses solid materials as the gain medium – the material that amplifies the light energy to produce laser emissions. In contrast to gas or liquid lasers, solid-state lasers use a crystal, ceramic, or glass as the gain medium. The active laser medium in solid-state lasers is typically doped with rare earth ions, such as neodymium (Nd), yttrium (Y), erbium (Er), or thulium (Tm).
The most common type of solid-state laser is the neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. In this laser, neodymium ions are doped into a crystal lattice made up of yttrium, aluminum, and garnet (YAG). The Nd:YAG laser emits light at a wavelength of 1064 nanometers (nm), which can be frequency-doubled to produce emissions at 532 nm.
Solid-state lasers have several advantages over other types of lasers, including high efficiency, long lifetimes, and compact size. They are widely used in various applications, such as material processing, medical treatments, scientific research, and military technology.
Laser therapy, also known as phototherapy or laser photobiomodulation, is a medical treatment that uses low-intensity lasers or light-emitting diodes (LEDs) to stimulate healing, reduce pain, and decrease inflammation. It works by promoting the increase of cellular metabolism, blood flow, and tissue regeneration through the process of photobiomodulation.
The therapy can be used on patients suffering from a variety of acute and chronic conditions, including musculoskeletal injuries, arthritis, neuropathic pain, and wound healing complications. The wavelength and intensity of the laser light are precisely controlled to ensure a safe and effective treatment.
During the procedure, the laser or LED device is placed directly on the skin over the area of injury or discomfort. The non-ionizing light penetrates the tissue without causing heat or damage, interacting with chromophores in the cells to initiate a series of photochemical reactions. This results in increased ATP production, modulation of reactive oxygen species, and activation of transcription factors that lead to improved cellular function and reduced pain.
In summary, laser therapy is a non-invasive, drug-free treatment option for various medical conditions, providing patients with an alternative or complementary approach to traditional therapies.
"Light coagulation," also known as "laser coagulation," is a medical term that refers to the use of laser technology to cauterize (seal or close) tissue. This procedure uses heat generated by a laser to cut, coagulate, or destroy tissue. In light coagulation, the laser beam is focused on the blood vessels in question, causing the blood within them to clot and the vessels to seal. This can be used for various medical purposes, such as stopping bleeding during surgery, destroying abnormal tissues (like tumors), or treating eye conditions like diabetic retinopathy and age-related macular degeneration.
It's important to note that this is a general definition, and the specific use of light coagulation may vary depending on the medical specialty and the individual patient's needs. As always, it's best to consult with a healthcare professional for more detailed information about any medical procedure or treatment.
Nitrogen isotopes are different forms of the nitrogen element (N), which have varying numbers of neutrons in their atomic nuclei. The most common nitrogen isotope is N-14, which contains 7 protons and 7 neutrons in its nucleus. However, there are also heavier stable isotopes such as N-15, which contains one extra neutron.
In medical terms, nitrogen isotopes can be used in research and diagnostic procedures to study various biological processes. For example, N-15 can be used in a technique called "nitrogen-15 nuclear magnetic resonance (NMR) spectroscopy" to investigate the metabolism of nitrogen-containing compounds in the body. Additionally, stable isotope labeling with nitrogen-15 has been used in clinical trials and research studies to track the fate of drugs and nutrients in the body.
In some cases, radioactive nitrogen isotopes such as N-13 or N-16 may also be used in medical imaging techniques like positron emission tomography (PET) scans to visualize and diagnose various diseases and conditions. However, these applications are less common than the use of stable nitrogen isotopes.
Erbium is a chemical element with the symbol "Er" and atomic number 68. It is a rare earth element that belongs to the lanthanide series in the periodic table. Erbium is not naturally found in its pure form, but it is typically extracted from minerals such as xenotime and bastnasite.
In medical terms, erbium is used in the form of erbium-doped yttrium aluminum garnet (Er:YAG) lasers for various surgical procedures. These lasers emit light at a wavelength of 2940 nanometers, which is highly absorbed by water and therefore ideal for cutting and coagulating tissue with minimal thermal damage to surrounding tissues. Erbium lasers are commonly used in dermatology and ophthalmology for procedures such as skin resurfacing, removal of tattoos and birthmarks, and cataract surgery.
Oxygen isotopes are different forms or varieties of the element oxygen that have the same number of protons in their atomic nuclei, which is 8, but a different number of neutrons. The most common oxygen isotopes are oxygen-16 (^{16}O), which contains 8 protons and 8 neutrons, and oxygen-18 (^{18}O), which contains 8 protons and 10 neutrons.
The ratio of these oxygen isotopes can vary in different substances, such as water molecules, and can provide valuable information about the origins and history of those substances. For example, scientists can use the ratio of oxygen-18 to oxygen-16 in ancient ice cores or fossilized bones to learn about past climate conditions or the diets of ancient organisms.
In medical contexts, oxygen isotopes may be used in diagnostic tests or treatments, such as positron emission tomography (PET) scans, where a radioactive isotope of oxygen (such as oxygen-15) is introduced into the body and emits positrons that can be detected by specialized equipment to create detailed images of internal structures.
Radioimmunotherapy (RIT) is a medical treatment that combines the specificity of antibodies and the therapeutic effects of radiation to target and destroy cancer cells. It involves the use of radioactive isotopes, which are attached to monoclonal antibodies, that recognize and bind to antigens expressed on the surface of cancer cells. Once bound, the radioactivity emitted from the isotope irradiates the cancer cells, causing damage to their DNA and leading to cell death. This targeted approach helps minimize radiation exposure to healthy tissues and reduces side effects compared to conventional radiotherapy techniques. RIT has been used in the treatment of various hematological malignancies, such as non-Hodgkin lymphoma, and is being investigated for solid tumors as well.
Carbon isotopes are variants of the chemical element carbon that have different numbers of neutrons in their atomic nuclei. The most common and stable isotope of carbon is carbon-12 (^{12}C), which contains six protons and six neutrons. However, carbon can also come in other forms, known as isotopes, which contain different numbers of neutrons.
Carbon-13 (^{13}C) is a stable isotope of carbon that contains seven neutrons in its nucleus. It makes up about 1.1% of all carbon found on Earth and is used in various scientific applications, such as in tracing the metabolic pathways of organisms or in studying the age of fossilized materials.
Carbon-14 (^{14}C), also known as radiocarbon, is a radioactive isotope of carbon that contains eight neutrons in its nucleus. It is produced naturally in the atmosphere through the interaction of cosmic rays with nitrogen gas. Carbon-14 has a half-life of about 5,730 years, which makes it useful for dating organic materials, such as archaeological artifacts or fossils, up to around 60,000 years old.
Carbon isotopes are important in many scientific fields, including geology, biology, and medicine, and are used in a variety of applications, from studying the Earth's climate history to diagnosing medical conditions.
Intra-articular injections refer to the administration of medication directly into a joint space. This route of administration is used for treating various joint conditions such as inflammation, pain, and arthritis. Commonly injected medications include corticosteroids, local anesthetics, and viscosupplementation agents. The procedure is usually performed using imaging guidance, like ultrasound or fluoroscopy, to ensure accurate placement of the medication within the joint.
A posterior capsulotomy is a surgical procedure that involves making an opening in the back part (posterior) of the lens capsule, which is a thin, clear membrane that holds the lens in place inside the eye. This procedure is typically performed to treat after-cataract, also known as posterior capsular opacification (PCO), which can cause vision loss or disturbance after cataract surgery. During cataract surgery, the cloudy natural lens of the eye is removed and replaced with an artificial intraocular lens (IOL). However, sometimes the back part of the lens capsule may become hazy or opaque over time, leading to visual symptoms similar to those experienced before cataract surgery.
In a posterior capsulotomy, a laser (usually a YAG laser) is used to create an opening in the cloudy posterior capsule, allowing light to pass through and restoring clear vision. The procedure is typically quick, painless, and performed as an outpatient procedure in a doctor's office or clinic. Patients may experience some side effects such as floaters, glare, or flashes of light after the procedure, but these usually resolve within a few days or weeks.
I'm sorry for any confusion, but "Ytterbium" is not a medical term. It is a chemical element with the symbol "Yb" and atomic number 70. Ytterbium is a rare earth metal that is silvery white, soft, malleable, and has many uses in scientific research, particularly in the field of laser technology.
