Idiopathic pulmonary haemosiderosis. Epidemiology, pathogenic aspects and diagnosis. (1/132)
Idiopathic pulmonary haemosiderosis (IPH) is a rare clinical entity characterized by recurrent episodes of diffuse alveolar haemorrhage, often presenting with haemoptysis. Many patients have iron deficiency anaemia due to deposition of haemosiderin iron in the alveoli, and eventually develop moderate pulmonary fibrosis. Typically, intensive search for an aetiology ends up negative. There is no evidence of pulmonary vasculitis or capillaritis. The aetiology is obscure, but may be an immunological or toxic mechanism causing a defect in the basement membrane of the pulmonary capillary. IPH affects both children and adults. During an acute episode, a chest X-ray demonstrates bilateral, alveolar infiltrates. Sputum examination discloses haemosiderin-laden alveolar macrophages. Diagnosis is established by lung biopsy (fiber-optic or thoracoscopic), showing large numbers of haemosiderin-laden macrophages in the alveoli and without evidence of capillaritis or deposition of immunoglobulins. Corticosteroids and/or immunosuppressive drugs may be effective during an acute bleeding episode, and may in some patients improve symptoms and prognosis on the long-term, but the response to treatment displays great interindividual variation. (+info)Histopathologic analysis of foci of signal loss on gradient-echo T2*-weighted MR images in patients with spontaneous intracerebral hemorrhage: evidence of microangiopathy-related microbleeds. (2/132)
BACKGROUND AND PURPOSE: Patients with spontaneous intracerebral hemorrhage (ICH) frequently have small areas of signal loss on gradient-echo T2*-weighted MR images, which have been suggested to represent remnants of previous microbleeds. Our aim was to provide histopathologic support for this assumption and to clarify whether the presence and location of microbleeds were associated with microangiopathy. METHODS: We performed MR imaging and correlative histopathologic examination in 11 formalin-fixed brains of patients who had died of an ICH (age range, 45-90 years). RESULTS: Focal areas of signal loss on MR images were noted in seven brains. They were seen in a corticosubcortical location in six brains, in the basal ganglia/thalami in five, and infratentorially in three specimens. Histopathologic examination showed focal hemosiderin deposition in 21 of 34 areas of MR signal loss. No other corresponding abnormalities were found; however, hemosiderin deposits were noted without MR signal changes in two brains. All specimens with MR foci of signal loss showed moderate to severe fibrohyalinosis, and there was additional evidence of amyloid angiopathy in two of those brains. CONCLUSION: Small areas of signal loss on gradient echo T2*-weighted images indicate previous extravasation of blood and are related to bleeding-prone microangiopathy of different origins. (+info)Alveolar haemorrhage in a case of high altitude pulmonary oedema. (3/132)
A case of high altitude pulmonary oedema (HAPE) in a climber who made a rapid ascent on Mt McKinley (Denali), Alaska is described. The bronchoalveolar lavage (BAL) fluid contained increased numbers of red blood cells and an abundance of haemosiderin laden macrophages consistent with alveolar haemorrhage. The timing of this finding indicates that alveolar haemorrhage began early during the ascent, well before the onset of symptoms. Although evidence of alveolar haemorrhage has been reported at necropsy in individuals dying of HAPE, previous reports have not shown the same abundance of haemosiderin laden macrophages in the BAL fluid. These findings suggest that alveolar haemorrhage is an early event in HAPE. (+info)Anthracycline cardiotoxicity in a black rhinoceros (Diceros bicornis): evidence for impaired antioxidant capacity compounded by iron overload. (4/132)
Two weeks before dying of congestive heart failure, a juvenile black rhinoceros (Diceros bicornis minor) received a single low dose of doxorubicin as part of combination chemotherapy for acute lymphoblastic leukemia. Diffuse hemosiderosis was present at necropsy in a pattern indicative of dietary iron overload, but unique iron-positive degenerative lesions were found in isolated myocardiocytes. Serum analyses revealed hyperferremia, 87% transferrin saturation, and 5- to 10-fold elevations in ferritin concentration, reflecting markedly increased tissue iron stores. Since both toxic and therapeutic effects of anthracyclines are mediated by formation of reactive free radicals via iron-catalyzed reactions, these observations suggest that iron overload may have enhanced myocardial susceptibility to cardiotoxic effects of doxorubicin. Impairments in other myocardial antioxidant defenses, such as deficiencies in catalase and glutathione S-transferase that are known to exist in rhinoceros erythrocytes, may have been underlying factors contributing to an inherent sensitivity of rhinoceros tissues to oxidant-induced injury. (+info)Low-frequency low-field magnetic susceptibility of ferritin and hemosiderin. (5/132)
Low-frequency low-field magnetic susceptibility measurements were made on four samples of mammalian tissue iron oxide deposits. The samples comprised: (1) horse spleen ferritin; (2) dugong liver hemosiderin; (3) thalassemic human spleen ferritin; and (4) crude thalassemic human spleen hemosiderin. These samples were chosen because Mossbauer spectroscopic measurements on the samples indicated that they exemplified the variation in magnetic and mineral structure found in mammalian tissue iron oxide deposits. The AC-magnetic susceptometry yielded information on the magnetization kinetics of the four samples indicating samples 1, 2, and 3 to be superparamagnetic with values of around 10(11) s(-1) for the pre-exponential frequency factor in the Neel-Arrhenius equation and values for characteristic magnetic anisotropy energy barriers in the range 250-400 K. Sample 4 was indicated to be paramagnetic at all temperatures above 1.3 K. The AC-magnetic susceptometry data also indicated a larger magnetic anisotropy energy distribution in the dugong liver sample compared with samples 1 and 3 in agreement with previous Mossbauer spectroscopic data on these samples. At temperatures below 200 K, samples 1-3 exhibited Curie-Weiss law behavior, indicating weak particle-particle interactions tending to favor antiparallel alignment of the particle magnetic moments. These interactions were strongest for the dugong liver hemosiderin, possibly reflecting the smaller separation between mineral particles in this sample. This is the first magnetic susceptometry study of hemosiderin iron deposits and demonstrates that the AC-magnetic susceptometry technique is a fast and informative method of studying such tissue iron oxide deposits. (+info)Benign transport of breast epithelium into axillary lymph nodes after biopsy. (6/132)
The most important prognostic indicator of distant metastasis in breast cancer is histologic documentation of axillary lymph node metastasis. Controversy exists about the importance of micrometastases (< 0.2 cm), and current pathology practice includes a careful search for their presence. We describe the histologic findings in a series of axillary lymph node dissections taken approximately 2 weeks after breast biopsy. Each case has limited presence of epithelial cells in the subcapsular sinus of a draining lymph node that we attribute to mechanical transport of tumor and/or normal breast epithelium secondary to the previous surgical or needle manipulation. These cells were accompanied by hemosiderin-laden macrophages and damaged RBCs. While the clinical implication of these findings is unknown, we believe that it will be of no clinical significance and have no untoward prognostic effect. (+info)Iron overload and kidney lysosomes. (7/132)
Iron overload has been associated with damage of the liver and other organs of patients with primary or secondary increased iron load. In order to study the effect of iron overload on the pathophysiology of kidney lysosomes, experimentally induced iron overload models were employed. Iron overload was achieved through intraperitoneal injections of Fe-dextran (Imferon) in male rats, at different final iron concentrations (825 and 1650 mg/kg, single and double dose groups respectively). Controls were injected with dextran following a similar protocol. The animals were killed at different time points after the last injection. Subcellular fractionation studies of kidney homogenates were carried out by differential centrifugation and density gradient centrifugation. The kidney iron load was increased with both doses. Iron appeared to accumulate mainly in the lysosomes, bringing about distinct changes in the behaviour of the organelles as judged by subcellular fractionation studies. Lysosomes became more fragile and showed increased density. The extent of the above changes seemed to correlate with the extent and duration of iron accumulation and could be reversed when the iron load was reduced. (+info)Ferritin iron absorption in man. (8/132)
The iron absorption from ferritin and hemosiderin biosynthetically labeled with radioiron was studied in 108 subjects. The geometric mean absorption of ferritin iron in both normal and iron-deficient subjects was 1.9 percent. Its mean absorption ranged from 0.9 percent in normal subjects to 2.5 percent in subjects with moderate iron deficiency and 5.7 percent in subjects with marked iron deficiency. The administration of this iron compound with vegetals in a meal showed distinctly lower absorption values than the absorption from either maize, wheat, or soybean. Ferritin iron absorption was also different from that of ferric chloride when they were administered together as a drink or mixed with maize or liver. The iron absorption from ferritin was markedly increased when it was administered with either meat or liver, but it did not reach the absorption level of these foods. It is still to be elucidated whether the difference in iron absorption between ferritin and vegetable foods administered together reflect that this iron is incompletely miscible with a nonheme iron pool or that it really forms a third iron pool. (+info)Hemosiderin is a golden-brown pigment that consists of iron-containing protein complexes called ferritin and ferrikinase. It is insoluble in water and forms as a result of the breakdown of hemoglobin in the reticuloendothelial system, primarily in macrophages. Hemosiderin deposits can be found in various tissues and organs, such as the spleen, liver, and brain, under conditions of increased red blood cell destruction or impaired iron metabolism. These deposits are often associated with diseases such as hemochromatosis, thalassemia, and chronic inflammation.
Hemosiderosis is a medical condition characterized by the abnormal accumulation of hemosiderin, an iron-containing protein, in various organs and tissues of the body. Hemosiderin is derived from the breakdown of hemoglobin, which is the oxygen-carrying protein in red blood cells. When there is excessive breakdown of red blood cells or impaired clearance of hemosiderin, it can lead to its accumulation in organs such as the liver, spleen, and lungs.
Hemosiderosis can be classified into two types: primary and secondary. Primary hemosiderosis is a rare condition that is caused by genetic disorders affecting red blood cells, while secondary hemosiderosis is more common and is associated with various conditions that cause excessive breakdown of red blood cells or chronic inflammation. These conditions include hemolytic anemias, repeated blood transfusions, liver diseases, infections, and certain autoimmune disorders.
The accumulation of hemosiderin can lead to tissue damage and organ dysfunction, particularly in the lungs, where it can cause pulmonary fibrosis, and in the heart, where it can lead to heart failure. Hemosiderosis is typically diagnosed through a combination of medical history, physical examination, and laboratory tests, including blood tests and imaging studies such as chest X-rays or MRI scans. Treatment of hemosiderosis depends on the underlying cause and may include medications, blood transfusions, or supportive care to manage symptoms and prevent complications.
Siderosis is a medical condition characterized by the abnormal accumulation of iron in various tissues and organs, most commonly in the lungs. This occurs due to the repeated inhalation of iron-containing dusts or fumes, which can result from certain industrial processes such as welding, mining, or smelting.
In the lungs, this iron deposit can lead to inflammation and fibrosis, potentially causing symptoms like coughing, shortness of breath, and decreased lung function. It is important to note that siderosis itself is not contagious or cancerous, but there may be an increased risk for lung cancer in individuals with severe and prolonged exposure to iron-containing particles.
While siderosis is generally non-reversible, the progression of symptoms can often be managed through medical interventions and environmental modifications to reduce further exposure to iron-containing dusts or fumes.
Forensic pathology is a subspecialty of pathology that focuses on determining the cause and manner of death by examining a corpse. It involves applying scientific knowledge and techniques to investigate criminal or suspicious deaths, often in conjunction with law enforcement agencies. A forensic pathologist performs autopsies (postmortem examinations) to evaluate internal and external injuries, diseases, and other conditions that may have contributed to the individual's death. They also collect evidence such as tissue samples, which can be used for toxicological, microbiological, or histological analysis. The information gathered by forensic pathologists is crucial in helping to establish the facts surrounding a person's death and assisting legal proceedings.
A dugong is a large marine mammal that belongs to the family Dugongidae. Its scientific name is Dugong dugon. It is also known as the sea cow because of its habit of feeding on seagrasses. Dugongs are found in warm coastal waters of the Indian and Pacific Oceans, ranging from East Africa to Vanuatu in the west and from Japan to Australia in the east. They can grow up to 3 meters in length and weigh between 200-500 kilograms.
Dugongs have a streamlined body with a flat, paddle-like tail and two flippers. Their skin is thick and wrinkled, and they are usually gray or brownish-gray in color. Dugongs have a unique feeding apparatus that allows them to graze on seagrasses, which include specialized lips and teeth.
Dugongs are social animals that live in small groups called herds. They communicate with each other using a variety of sounds, including clicks, chirps, and whistles. Dugongs have a long lifespan, with some individuals living up to 70 years or more.
Unfortunately, dugongs are threatened by various human activities, such as hunting, habitat loss, and entanglement in fishing nets. They are currently listed as vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.
A cavernous hemangioma in the central nervous system (CNS) refers to a type of benign vascular tumor that is made up of dilated and thin-walled blood vessels. These tumors are called "cavernous" because they are filled with blood-filled sacs or "caverns."
When these hemangiomas occur in the CNS, which includes the brain and spinal cord, they can cause various neurological symptoms depending on their size and location. Small hemangiomas may not cause any symptoms at all, while larger ones can cause seizures, headaches, weakness, or sensory changes.
Cavernous hemangiomas in the CNS are typically congenital, meaning that they are present at birth. However, they may not become symptomatic until later in life. Treatment options for cavernous hemangiomas in the CNS include observation, surgery, or radiation therapy, depending on the size, location, and symptoms caused by the tumor.
Ferritin is a protein in iron-metabolizing cells that stores iron in a water-soluble form. It is found inside the cells (intracellular) and is released into the bloodstream when the cells break down or die. Measuring the level of ferritin in the blood can help determine the amount of iron stored in the body. High levels of ferritin may indicate hemochromatosis, inflammation, liver disease, or other conditions. Low levels of ferritin may indicate anemia, iron deficiency, or other conditions.
Biological pigments are substances produced by living organisms that absorb certain wavelengths of light and reflect others, resulting in the perception of color. These pigments play crucial roles in various biological processes such as photosynthesis, vision, and protection against harmful radiation. Some examples of biological pigments include melanin, hemoglobin, chlorophyll, carotenoids, and flavonoids.
Melanin is a pigment responsible for the color of skin, hair, and eyes in animals, including humans. Hemoglobin is a protein found in red blood cells that contains a porphyrin ring with an iron atom at its center, which gives blood its red color and facilitates oxygen transport. Chlorophyll is a green pigment found in plants, algae, and some bacteria that absorbs light during photosynthesis to convert carbon dioxide and water into glucose and oxygen. Carotenoids are orange, yellow, or red pigments found in fruits, vegetables, and some animals that protect against oxidative stress and help maintain membrane fluidity. Flavonoids are a class of plant pigments with antioxidant properties that have been linked to various health benefits.
In the context of medicine, iron is an essential micromineral and key component of various proteins and enzymes. It plays a crucial role in oxygen transport, DNA synthesis, and energy production within the body. Iron exists in two main forms: heme and non-heme. Heme iron is derived from hemoglobin and myoglobin in animal products, while non-heme iron comes from plant sources and supplements.
The recommended daily allowance (RDA) for iron varies depending on age, sex, and life stage:
* For men aged 19-50 years, the RDA is 8 mg/day
* For women aged 19-50 years, the RDA is 18 mg/day
* During pregnancy, the RDA increases to 27 mg/day
* During lactation, the RDA for breastfeeding mothers is 9 mg/day
Iron deficiency can lead to anemia, characterized by fatigue, weakness, and shortness of breath. Excessive iron intake may result in iron overload, causing damage to organs such as the liver and heart. Balanced iron levels are essential for maintaining optimal health.
I'm sorry for any confusion, but "Venezuela" is not a medical term. It is the name of a country located in South America, known officially as the Bolivarian Republic of Venezuela. If you have any questions about medical terms or health-related topics, I would be happy to try and help answer those for you!
"Iron radioisotopes" refer to specific forms of the element iron that have unstable nuclei and emit radiation. These isotopes are often used in medical imaging and treatment procedures due to their ability to be detected by specialized equipment. Common iron radioisotopes include Iron-52, Iron-55, Iron-59, and Iron-60. They can be used as tracers to study the distribution, metabolism, or excretion of iron in the body, or for targeted radiation therapy in conditions such as cancer.
Medical Definition:
Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic imaging technique that uses a strong magnetic field and radio waves to create detailed cross-sectional or three-dimensional images of the internal structures of the body. The patient lies within a large, cylindrical magnet, and the scanner detects changes in the direction of the magnetic field caused by protons in the body. These changes are then converted into detailed images that help medical professionals to diagnose and monitor various medical conditions, such as tumors, injuries, or diseases affecting the brain, spinal cord, heart, blood vessels, joints, and other internal organs. MRI does not use radiation like computed tomography (CT) scans.
