Organ-specific (localized) synthesis of Ig light chain amyloid. (1/144)
Ig amyloidosis is usually a systemic disease with multisystem involvement. However, in a significant number of cases amyloid deposition is limited to one specific organ. It has not been determined if the Ig light chain (LC) amyloid precursor protein in localized amyloidosis is synthesized by circulating plasma cells with targeting of the amyloid fibril-forming process to one specific organ, or whether the synthesis of Ig LC and fibril formation occurs entirely as a localized process. In the present study local synthesis of an amyloid fibril precursor LC was investigated. Amyloid fibrils were isolated from a ureter that was obstructed by extensive infiltration of the wall with amyloid. Amino acid sequence analysis of the isolated fibril subunit protein proved it to be derived from a lambdaII Ig LC. Plasma cells within the lesion stained positively with labeled anti-lambda Ab and by in situ hybridization using an oligonucleotide probe specific for lambda-LC mRNA. RT-PCR of mRNA extracted from the tumor and direct DNA sequencing gave the nucleotide sequence coding specifically for the lambdaII amyloid subunit protein, thus confirming local synthesis of the LC protein. (+info)Sonographic diagnosis of ureteral tumors. (2/144)
We present our experience with transabdominal ultrasonographic diagnosis of ureteral tumors. During the years 1989 to 1998, 16 patients were diagnosed as having ureteral tumors. These patients were referred for sonographic examination for evaluation of hematuria (seven patients) or flank pain (four patients) or for follow-up screening in patients who were asymptomatic but at high risk for transitional cell carcinoma because of known past bladder tumor (five patients). Ten of these patients underwent intravenous urography examination, three patients had retrograde pyelography, and 11 patients underwent CT scanning. Ultrasonography revealed the ureteral tumors in all 16 patients, which appeared as hypoechoic intraluminal soft tissue. Three tumors were localized in the upper ureter, four in the middle ureter, and nine in the distal ureter. The degree of ureterohydronephrosis was minimal (two cases), mild (five cases), moderate (eight cases), or severe (one case). Eleven tumors caused local widening of the ureteral diameter. On intravenous urography, four patients had a nonfunctioning kidney, three patients had unexplained ureterohydronephrosis, and three patients showed ureteral filling defects, of which only two had irregular contours. On retrograde pyelography, two patients had filling defects (one of which with smooth margins), and one had a truncated ureter. On CT the tumor was clearly demonstrated in only seven patients. We found that ultrasonography can be a useful diagnostic tool in the workup of ureteral tumors. (+info)Cytogenetic monoclonality in multifocal uroepithelial carcinomas: evidence of intraluminal tumour seeding. (3/144)
Twenty-one multifocal urinary tract transitional cell carcinomas, mostly bladder tumours, from a total of six patients were processed for cytogenetic analysis after short-term culturing of the tumour cells. Karyotypically related, often identical, cytogenetically complex clones were found in all informative tumours from each case, including the recurrent tumours. Rearrangement of chromosome 9, leading to loss of material from the short and/or the long arm, was seen in all cases, indicating that this is an early, pathogenetically important event in transitional cell carcinogenesis. The presence of related clones with great karyotypic similarity in anatomically distinct tumours from the same bladder indicates that multifocal uroepithelial tumours have a monoclonal origin and arise via intraluminal seeding of viable cancer cells shed from the original tumour. Later lesions may develop also from cells shed from the so called second primary tumours. The relatively complex karyotypes seen in all lesions from most cases argue that the seeding of tumour cells is a late event that succeeds the acquisition by them of multiple secondary genetic abnormalities. (+info)Transitional cell carcinoma of the ureter and struvite calculi. (4/144)
CONTEXT: The association of primary carcinoma of the ureter and lithiasis is extremely rare. We report a rare case of a primary carcinoma of the ureter with corariform calculus. CASE REPORT: 60-year-old phaeodermal female, reported a history of right-side nephritic colic, hyperthermia and pyuria during the past 20 years and had received treatment for urinary infections a number of times. The first clinical presentation was related to lithiasis and the tumor had not been shown up by excretory urography, cystoscopy or ultrasonography. Two months after the calculus had been eliminated, the patient began to have serious symptoms and a grade III transitional cell carcinoma of the ureter was discovered. Total nephroureterectomy and M.V.A.C. (Methotrexate + Vinblastina + Doxo Rubicina + Cisplatina) chemotherapy were tried unsuccessfully. In this report we emphasize the diagnostic difficulty caused by the concomitant presence of the two pathologies. In our opinion, the rapid evolution in this case is directly related to the high grade of the tumor. (+info)Gemcitabine plus cisplatin, an active regimen in advanced urothelial cancer: a phase II trial of the National Cancer Institute of Canada Clinical Trials Group. (5/144)
PURPOSE: To evaluate the efficacy and toxicity of gemcitabine (2', 2'-difluorodeoxycytidine) plus cisplatin in previously untreated patients with advanced transitional-cell carcinoma. PATIENTS AND METHODS: Thirty-one patients with measurable advanced transitional-cell carcinoma who had received no prior chemotherapy for metastatic disease were scheduled to receive gemcitabine 1,000 mg/m(2) intravenously over 30 minutes on days 1, 8, and 15 and cisplatin 70 mg/m(2) over 1 hour on day 2 of a 28-day cycle. Prior adjuvant or neoadjuvant therapy for locally advanced disease was allowed if this was completed more than 1 year before study entry. RESULTS: There were six complete responses and 10 partial responses in 28 assessable patients, for an overall response rate of 16 of 28 (57%). The response rate on an intent-to-treat basis was 16 of 31 patients (52%). The median survival is 13.2 months, with 18 patients still alive at this time. Toxicity was primarily hematologic, with 12 of 31 patients (39%) having > or = grade 3 granulocytopenia and 17 of 31 (55%) having > or = grade 3 thrombocytopenia. Two patients had febrile neutropenia. All patients required a dose modification of gemcitabine at some point in their therapy; the primary reason was thrombocytopenia and/or neutropenia. CONCLUSION: Gemcitabine plus cisplatin is an active regimen for the treatment of urothelial cancer. (+info)Urothelial cancer at different tumour sites: role of smoking and habitual intake of analgesics and laxatives. Results of the Berlin Urothelial Cancer Study. (6/144)
BACKGROUND: In Germany about 20000 new cases of urothelial cancer (UC) and about 7500 deaths from bladder cancer alone occur each year. Among the manifold risk factors, little research has been done on the role of smoking and the habitual intake of analgesics and laxatives-practices that are common in parts of the German population. The aim of this study is to define the proportion of risk derived from these preventable habits for the development of UC at its different sites. Subjects and methods. A case-control study in the area of the former West Berlin was performed from 1990 to 1995 including all newly diagnosed incident cases of UC from the eight hospitals of the study area. Study subjects and population-based controls individually matched by age (+/-2 years) and sex were evaluated by a standardized face-to-face interview about the lifelong exposure to cigarette smoking, analgesics, and laxatives. Adjusted risk analysis was carried out for the main exposure variables in relation to the different sites of UC in the bladder, ureter, and renal pelvis. RESULTS: Six hundred and forty-seven cases of UC (571 bladder, 25 ureter, and 51 renal pelvis) and an identical number of controls were included in the analysis (response rate in cases, 84.6%; in controls, 70.2%). Smoking increased the risk of bladder cancer (BC) by an odds ratio (OR) of 3.22 (95% confidence interval (CI) 2.29-4.52), that of ureter (URC) or renal pelvis cancer (RPC) together by OR 6.20 (95% CI 2.04-18.81), and that of RPC alone by OR 5.91 (95% CI 1.47-23.66). Ex-smoking was associated with an increased risk for BC (OR 1.55, 95% CI 1.10-2.19). Intake of more than 1 kg of phenacetin in analgesic mixtures was associated with an OR of 5.28 for RPC (intake of > or = 1 kg paracetamol, OR 3.27; > or = 1 kg pyrazolones, 1.12) and 0.75 for BC (not significant). Laxatives significantly increased the risk of BC (OR 2.14, 95% CI 1.26-3.63) and RPC/URC (OR 9.62, 95% CI 1. 01-91.24) in both sexes. CONCLUSION: Habitual risks from smoking and intake of laxatives significantly contribute to the development of UC, especially of the renal pelvis and ureter cancer. Intake of at least 1 kg of analgesic substances (anilides, pyrazolones) as calculated from this study base is associated with increased but not significant risks for RPC. These data underline that restrictive and educational measurements focusing on common habits would have a strong impact on preventing UC in Germany. (+info)An unusual presentation of enzootic bovine leukosis. (7/144)
A 6-year-old, Holstein x Simmental cow diagnosed with pyelonephritis had increasing difficulty rising and became recumbent, despite treatment with antibiotics. A serological test for the bovine leukemia virus was positive; at necropsy, the left kidney and ureter and the myocardium showed lesions of lymphosarcoma, confirmed by histology. (+info)Synchronous presentation of primary renal adenocarcinoma and contralateral ureteric metastasis. (8/144)
The synchronous presentation of a primary renal adenocarcinoma and contralateral uretic metastasis is discussed. The pattern of immunohistochemical staining confirmed that the contralateral ureteric obstruction was the result of a metastasis from the primary renal adenocarcinoma. (+info)Ureteral neoplasms refer to abnormal growths or tumors in the ureters, which are the tubes that carry urine from the kidneys to the bladder. These neoplasms can be benign (non-cancerous) or malignant (cancerous). Benign ureteral neoplasms are rare and usually do not pose a significant health risk, although they may need to be removed if they cause obstructions or other complications.
Malignant ureteral neoplasms, on the other hand, are more serious and can spread to other parts of the body. The most common type of malignant ureteral neoplasm is transitional cell carcinoma (TCC), which arises from the cells that line the inside of the ureters. Other types of malignant ureteral neoplasms include squamous cell carcinoma, adenocarcinoma, and sarcoma.
Symptoms of ureteral neoplasms may include hematuria (blood in the urine), flank pain, weight loss, and fatigue. Diagnosis typically involves imaging tests such as CT scans or MRIs, as well as urine cytology and biopsy to confirm the presence of cancer cells. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.
Pancreatic neoplasms refer to abnormal growths in the pancreas that can be benign or malignant. The pancreas is a gland located behind the stomach that produces hormones and digestive enzymes. Pancreatic neoplasms can interfere with the normal functioning of the pancreas, leading to various health complications.
Benign pancreatic neoplasms are non-cancerous growths that do not spread to other parts of the body. They are usually removed through surgery to prevent any potential complications, such as blocking the bile duct or causing pain.
Malignant pancreatic neoplasms, also known as pancreatic cancer, are cancerous growths that can invade and destroy surrounding tissues and organs. They can also spread (metastasize) to other parts of the body, such as the liver, lungs, or bones. Pancreatic cancer is often aggressive and difficult to treat, with a poor prognosis.
There are several types of pancreatic neoplasms, including adenocarcinomas, neuroendocrine tumors, solid pseudopapillary neoplasms, and cystic neoplasms. The specific type of neoplasm is determined through various diagnostic tests, such as imaging studies, biopsies, and blood tests. Treatment options depend on the type, stage, and location of the neoplasm, as well as the patient's overall health and preferences.
Neoplasms are abnormal growths of cells or tissues in the body that serve no physiological function. They can be benign (non-cancerous) or malignant (cancerous). Benign neoplasms are typically slow growing and do not spread to other parts of the body, while malignant neoplasms are aggressive, invasive, and can metastasize to distant sites.
Neoplasms occur when there is a dysregulation in the normal process of cell division and differentiation, leading to uncontrolled growth and accumulation of cells. This can result from genetic mutations or other factors such as viral infections, environmental exposures, or hormonal imbalances.
Neoplasms can develop in any organ or tissue of the body and can cause various symptoms depending on their size, location, and type. Treatment options for neoplasms include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapy, among others.
Neoplasms: Neoplasms refer to abnormal growths of tissue that can be benign (non-cancerous) or malignant (cancerous). They occur when the normal control mechanisms that regulate cell growth and division are disrupted, leading to uncontrolled cell proliferation.
Cystic Neoplasms: Cystic neoplasms are tumors that contain fluid-filled sacs or cysts. These tumors can be benign or malignant and can occur in various organs of the body, including the pancreas, ovary, and liver.
Mucinous Neoplasms: Mucinous neoplasms are a type of cystic neoplasm that is characterized by the production of mucin, a gel-like substance produced by certain types of cells. These tumors can occur in various organs, including the ovary, pancreas, and colon. Mucinous neoplasms can be benign or malignant, and malignant forms are often aggressive and have a poor prognosis.
Serous Neoplasms: Serous neoplasms are another type of cystic neoplasm that is characterized by the production of serous fluid, which is a thin, watery fluid. These tumors commonly occur in the ovary and can be benign or malignant. Malignant serous neoplasms are often aggressive and have a poor prognosis.
In summary, neoplasms refer to abnormal tissue growths that can be benign or malignant. Cystic neoplasms contain fluid-filled sacs and can occur in various organs of the body. Mucinous neoplasms produce a gel-like substance called mucin and can also occur in various organs, while serous neoplasms produce thin, watery fluid and commonly occur in the ovary. Both mucinous and serous neoplasms can be benign or malignant, with malignant forms often being aggressive and having a poor prognosis.
Skin neoplasms refer to abnormal growths or tumors in the skin that can be benign (non-cancerous) or malignant (cancerous). They result from uncontrolled multiplication of skin cells, which can form various types of lesions. These growths may appear as lumps, bumps, sores, patches, or discolored areas on the skin.
Benign skin neoplasms include conditions such as moles, warts, and seborrheic keratoses, while malignant skin neoplasms are primarily classified into melanoma, squamous cell carcinoma, and basal cell carcinoma. These three types of cancerous skin growths are collectively known as non-melanoma skin cancers (NMSCs). Melanoma is the most aggressive and dangerous form of skin cancer, while NMSCs tend to be less invasive but more common.
It's essential to monitor any changes in existing skin lesions or the appearance of new growths and consult a healthcare professional for proper evaluation and treatment if needed.
Multiple primary neoplasms refer to the occurrence of more than one primary malignant tumor in an individual, where each tumor is unrelated to the other and originates from separate cells or organs. This differs from metastatic cancer, where a single malignancy spreads to multiple sites in the body. Multiple primary neoplasms can be synchronous (occurring at the same time) or metachronous (occurring at different times). The risk of developing multiple primary neoplasms increases with age and is associated with certain genetic predispositions, environmental factors, and lifestyle choices such as smoking and alcohol consumption.
Kidney neoplasms refer to abnormal growths or tumors in the kidney tissues that can be benign (non-cancerous) or malignant (cancerous). These growths can originate from various types of kidney cells, including the renal tubules, glomeruli, and the renal pelvis.
Malignant kidney neoplasms are also known as kidney cancers, with renal cell carcinoma being the most common type. Benign kidney neoplasms include renal adenomas, oncocytomas, and angiomyolipomas. While benign neoplasms are generally not life-threatening, they can still cause problems if they grow large enough to compromise kidney function or if they undergo malignant transformation.
Early detection and appropriate management of kidney neoplasms are crucial for improving patient outcomes and overall prognosis. Regular medical check-ups, imaging studies, and urinalysis can help in the early identification of these growths, allowing for timely intervention and treatment.
A "second primary neoplasm" is a distinct, new cancer or malignancy that develops in a person who has already had a previous cancer. It is not a recurrence or metastasis of the original tumor, but rather an independent cancer that arises in a different location or organ system. The development of second primary neoplasms can be influenced by various factors such as genetic predisposition, environmental exposures, and previous treatments like chemotherapy or radiation therapy.
It is important to note that the definition of "second primary neoplasm" may vary slightly depending on the specific source or context. In general medical usage, it refers to a new, separate cancer; however, in some research or clinical settings, there might be more precise criteria for defining and diagnosing second primary neoplasms.
Adenocarcinoma, mucinous is a type of cancer that begins in the glandular cells that line certain organs and produce mucin, a substance that lubricates and protects tissues. This type of cancer is characterized by the presence of abundant pools of mucin within the tumor. It typically develops in organs such as the colon, rectum, lungs, pancreas, and ovaries.
Mucinous adenocarcinomas tend to have a distinct appearance under the microscope, with large pools of mucin pushing aside the cancer cells. They may also have a different clinical behavior compared to other types of adenocarcinomas, such as being more aggressive or having a worse prognosis in some cases.
It is important to note that while a diagnosis of adenocarcinoma, mucinous can be serious, the prognosis and treatment options may vary depending on several factors, including the location of the cancer, the stage at which it was diagnosed, and the individual's overall health.
Thyroid neoplasms refer to abnormal growths or tumors in the thyroid gland, which can be benign (non-cancerous) or malignant (cancerous). These growths can vary in size and may cause a noticeable lump or nodule in the neck. Thyroid neoplasms can also affect the function of the thyroid gland, leading to hormonal imbalances and related symptoms. The exact causes of thyroid neoplasms are not fully understood, but risk factors include radiation exposure, family history, and certain genetic conditions. It is important to note that most thyroid nodules are benign, but a proper medical evaluation is necessary to determine the nature of the growth and develop an appropriate treatment plan.
Myeloproliferative disorders (MPDs) are a group of rare, chronic blood cancers that originate from the abnormal proliferation or growth of one or more types of blood-forming cells in the bone marrow. These disorders result in an overproduction of mature but dysfunctional blood cells, which can lead to serious complications such as blood clots, bleeding, and organ damage.
There are several subtypes of MPDs, including:
1. Chronic Myeloid Leukemia (CML): A disorder characterized by the overproduction of mature granulocytes (a type of white blood cell) in the bone marrow, leading to an increased number of these cells in the blood. CML is caused by a genetic mutation that results in the formation of the BCR-ABL fusion protein, which drives uncontrolled cell growth and division.
2. Polycythemia Vera (PV): A disorder characterized by the overproduction of all three types of blood cells - red blood cells, white blood cells, and platelets - in the bone marrow. This can lead to an increased risk of blood clots, bleeding, and enlargement of the spleen.
3. Essential Thrombocythemia (ET): A disorder characterized by the overproduction of platelets in the bone marrow, leading to an increased risk of blood clots and bleeding.
4. Primary Myelofibrosis (PMF): A disorder characterized by the replacement of normal bone marrow tissue with scar tissue, leading to impaired blood cell production and anemia, enlargement of the spleen, and increased risk of infections and bleeding.
5. Chronic Neutrophilic Leukemia (CNL): A rare disorder characterized by the overproduction of neutrophils (a type of white blood cell) in the bone marrow, leading to an increased number of these cells in the blood. CNL can lead to an increased risk of infections and organ damage.
MPDs are typically treated with a combination of therapies, including chemotherapy, targeted therapy, immunotherapy, and stem cell transplantation. The choice of treatment depends on several factors, including the subtype of MPD, the patient's age and overall health, and the presence of any comorbidities.
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.
Transitional cell carcinoma (TCC) is a type of cancer that develops in the transitional epithelium, which is the tissue that lines the inner surface of the urinary tract. This includes the renal pelvis, ureters, bladder, and urethra. Transitional cell carcinoma is the most common type of bladder cancer and can also occur in other parts of the urinary system.
Transitional cells are specialized epithelial cells that can stretch and change shape as the organs they line expand or contract. These cells normally have a flat, squamous appearance when at rest but become more cuboidal and columnar when the organ is full. Transitional cell carcinomas typically start in the urothelium, which is the innermost lining of the urinary tract.
Transitional cell carcinoma can be classified as non-invasive (also called papillary or superficial), invasive, or both. Non-invasive TCCs are confined to the urothelium and have not grown into the underlying connective tissue. Invasive TCCs have grown through the urothelium and invaded the lamina propria (a layer of connective tissue beneath the urothelium) or the muscle wall of the bladder.
Transitional cell carcinoma can also be categorized as low-grade or high-grade, depending on how abnormal the cancer cells look under a microscope and how likely they are to grow and spread. Low-grade TCCs tend to have a better prognosis than high-grade TCCs.
Treatment for transitional cell carcinoma depends on the stage and grade of the cancer, as well as other factors such as the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, or immunotherapy.
The kidney pelvis, also known as the renal pelvis, is the funnel-shaped part of the upper end of the ureter in the kidney. It receives urine from the minor and major calyces, which are extensions of the renal collecting tubules, and then drains it into the ureter, which carries it to the bladder for storage and eventual elimination from the body. The kidney pelvis is lined with transitional epithelium, which is designed to stretch and accommodate changes in urine volume.
I'm sorry for any confusion, but "handbooks" is a general term that refers to a booklet or guide containing information on a specific subject or set of procedures. It is not a medical term with a specific definition. There are many handbooks related to the medical field, such as medical terminology handbooks, clinical practice handbooks, or first aid handbooks, but each one contains different information depending on its purpose.
Urinary Bladder Neoplasms are abnormal growths or tumors in the urinary bladder, which can be benign (non-cancerous) or malignant (cancerous). Malignant neoplasms can be further classified into various types of bladder cancer, such as urothelial carcinoma, squamous cell carcinoma, and adenocarcinoma. These malignant tumors often invade surrounding tissues and organs, potentially spreading to other parts of the body (metastasis), which can lead to serious health consequences if not detected and treated promptly and effectively.
A kidney, in medical terms, is one of two bean-shaped organs located in the lower back region of the body. They are essential for maintaining homeostasis within the body by performing several crucial functions such as:
1. Regulation of water and electrolyte balance: Kidneys help regulate the amount of water and various electrolytes like sodium, potassium, and calcium in the bloodstream to maintain a stable internal environment.
2. Excretion of waste products: They filter waste products from the blood, including urea (a byproduct of protein metabolism), creatinine (a breakdown product of muscle tissue), and other harmful substances that result from normal cellular functions or external sources like medications and toxins.
3. Endocrine function: Kidneys produce several hormones with important roles in the body, such as erythropoietin (stimulates red blood cell production), renin (regulates blood pressure), and calcitriol (activated form of vitamin D that helps regulate calcium homeostasis).
4. pH balance regulation: Kidneys maintain the proper acid-base balance in the body by excreting either hydrogen ions or bicarbonate ions, depending on whether the blood is too acidic or too alkaline.
5. Blood pressure control: The kidneys play a significant role in regulating blood pressure through the renin-angiotensin-aldosterone system (RAAS), which constricts blood vessels and promotes sodium and water retention to increase blood volume and, consequently, blood pressure.
Anatomically, each kidney is approximately 10-12 cm long, 5-7 cm wide, and 3 cm thick, with a weight of about 120-170 grams. They are surrounded by a protective layer of fat and connected to the urinary system through the renal pelvis, ureters, bladder, and urethra.
