p53 and p16INK4A mutations during the progression of glomus tumor. (1/24)

Glomus tumors are significantly rare tumors of carotid body. The great majority of these tumors are benign in character. Here we present two brothers with hereditary glomus jugulare tumor who had consanguineous parents. Radiotherapy was applied approximately 8 and 10 years ago for treatment in both cases. Eight years later, one of these cases came to our notice due to relapse. The mutation pattern of p53, p57KIP2, p16INK4A and p15NK4B genes which have roles in the cell cycle, was analyzed in tumor samples obtained from the two affected cases in the initial phase and from one of these cases at relapse. The DNA sample obtained from the case in initial diagnosis phase revealed no p53, p57KIP2, p16INK4A or p15INK4B mutation. He is still in remission phase. Despite the lack of p53, p57KIP2, p16INK4A and p15INK4B mutation at initial diagnosis the tumor DNA of the other case in relapse revealed p53 codon 243 (ATG-->ATC; met-->ile) and p16 codon 97 (GAC-->AAC; asp-->asn) missense point mutations. No loss of heterozygosity in p53 and p16INK4A was observed by microsatellite analysis of tumoral tissues in these cases. P53 and p16INK4A mutations observed in relapse phase were in conserved regions of both genes. No previous reports have been published with these mutations in glomus tumor during progression. The mutation observed in this case may due to radiotherapy. In spite of this possibility, the missense point mutations in conserved region of p53 and p16INK4A genes may indicate the role of p53 and p16INK4A in tumor progression of glomus tumors.  (+info)

Imaging findings in schwannomas of the jugular foramen. (2/24)

BACKGROUND AND PURPOSE: Tumors of the cranial nerve sheath constitute 5% to 10% of all intracranial neoplasms, yet few articles have described their CT and MR characteristics. We report the imaging findings in a relatively large series of schwannomas of the jugular foramen, contrasting them with other disease entities, especially vestibular schwannomas and tumors of the glomus jugulare. METHODS: CT and/or MR studies of eight patients who underwent surgery for histologically proved schwannomas were reviewed retrospectively. One additional patient with an assumed schwannoma of the jugular foramen, who did not have surgery, was also included. RESULTS: Surgical findings showed schwannomas of the glossopharyngeal nerve in seven patients and tumor involvement of both the glossopharyngeal and vagal nerves in one patient. All tumors were partially located within the jugular foramen. Growth extending within the temporal bone was typical. Tumor extended into the posterior cranial fossa in all nine patients and produced mass effect on the brain stem and/or cerebellum in seven patients; in five patients, tumor extended below the skull base. On unenhanced CT scans, tumors were isodense with brain in six patients and hypodense in two. In seven patients, CT scans with bone algorithm showed an enlarged jugular foramen with sharply rounded bone borders and a sclerotic rim. On MR images, T1 signal from tumor was low and T2 signal was high relative to white matter in all patients. Contrast enhancement on CT and/or MR studies was strong in eight patients and moderate in one. CONCLUSION: Schwannoma of the jugular foramen is characteristically a sharply demarcated, contrast-enhancing tumor, typically centered on or based in an enlarged jugular foramen with sharply rounded bone borders and a sclerotic rim. Intraosseous extension may be marked.  (+info)

Stereotactic linear accelerater-based radiosurgery for the treatment of patients with glomus jugulare tumors. (3/24)

BACKGROUND: The optimal treatment for patients with glomus jugulare tumor (GJT) of the skull base remains controversial. Surgical excision is associated with a high incidence of cranial nerve injury, decreased quality of life, and high mortality. Fractionated radiotherapy is used to control the majority of these tumors, but disadvantages are a prolonged therapy interval and exposition of adjacent brain tissue to irradiation. The authors present the results of a study on 12 of 14 consecutively admitted patients who were treated using linear accelerator-based radiosurgery (LINAC-RS), an innovative method for the treatment of GJT. METHODS: From May 1991 to March 2001, 14 patients with GJT were treated with stereotactic LINAC-RS for continued growth of tumor or of remaining tumor after surgery. Twelve patients (9 women and 3 men; age range, 28-71 years; median age, 59 years) with a median follow-up of 4 years (range, 0.8-9,0 years), were selected for retrospective analysis. A median single dose of 15 grays (Gy; range, 11-20 Gy) was applied to the surface of the tumor. RESULTS: After undergoing LINAC-RS, 8 of 12 patients (67%) reported partial or complete subjective improvement, whereas complaints remained unchanged in 4 patients (33%). Neurologic status improved in 3 patients (25%) and remained unchanged in 8 patients (67%). Magnetic resonance images showed tumor shrinkage in 8 patients (67%) and no further progression in 4 patients (33%). CONCLUSIONS: LINAC-RS is an effective and safe therapy for patients with GJT and may be used as an alternative to surgical resection. Compared with fractionated radiotherapy, LINAC-RS has some advantages. However, to clarify the question of long-term tumor control, longer observation times are required.  (+info)

Intratumoral injection of cyanoacrylate glue in head and neck paragangliomas. (4/24)

BACKGROUND AND PURPOSE: Substantial intraoperative bleeding during surgical removal of head and neck paragangliomas may be a major problem in the management of these highly vascularized tumors. Traditional preoperative embolization via a transarterial approach has proved beneficial but is often limited by complex vascular anatomy and unfavorable locations. We report our experience with the preoperative devascularization of head and neck paragangliomas by using direct puncture and an intralesional injection of cyanoacrylate. METHODS: We retrospectively analyzed nine consecutive patients with head and neck paragangliomas who were referred for preoperative devascularization. Three patients were treated for carotid-body tumors; two for vagal lesions; and four, for jugular paragangliomas. Direct puncture of the lesion was performed by using roadmap fluoroscopic guidance. Acrylic glue was injected by using continuous biplane fluoroscopy. All patients underwent postembolization control angiography and immediate postoperative CT scanning. RESULTS: Angiograms showed that complete devascularization was achieved in all cervical glomus tumors, whereas subtotal devascularization was achieved in jugular paragangliomas. In this latter location, the injection of acrylic glue was limited by the potential risk of reflux into normal brain territory via feeders from the internal carotid or vertebral artery. The tumors were surgically removed and histologically examined. No technical or clinical complications related to the embolization procedure occurred. CONCLUSION: Percutaneous puncture of paragangliomas in the head and neck region and their preoperative devascularization by intralesional injection of acrylic glue is a feasible, safe, and effective technique.  (+info)

Intradural jugular foramen tumors. (5/24)

Eleven patients with jugular foramen lesions with or without extradural extension were operated at University Hospital of Campinas (UNICAMP), in Campinas, Brazil, between 1998 and 2001. Neck dissection, mastoidectomy without transposition of the facial nerve and myofascial flap reconstruction of the cranial base with an especially developed technique were carried out in 7 patients. Four patients were operated using retrosigmoid craniectomy. Total excision was accomplished in 9 cases. All patients did not show evidence of disease progression at least after 2 years follow-up. There was no mortality. New lower cranial nerve deficits occurred in 5 patients. Nine maintain or improved their preoperative status based on Karnofsky and Glasgow Outcome Scale. A complex anatomy of this region demand wide exposures for treat those tumors. For this reason, an adequate approach for curative resection of most lesions and an efficient skull base reconstruction decreasing postoperative morbidity are essential.  (+info)

Active succinate dehydrogenase (SDH) and lack of SDHD mutations in sporadic paragangliomas. (6/24)

BACKGROUND: Paragangliomas are benign, slow-growing tumours of the head and neck region. The candidate gene for familial and some sporadic paragangliomas, SDHD (succinate dehydrogenase, subunit D), has been mapped to the PGL1 locus in 11q23.3. MATERIALS AND METHODS: Normal and tumour DNA of 17 patients with sporadic paragangliomas were analysed by sequencing (SDHD, SDHB and SDHC genes), fluorescence in situ hybridisation (FISH). In addition, loss of heterozygosity (LOH) and succinate dehydrogenase (SDH) enzyme activity assays were performed. RESULTS AND CONCLUSION: Only two patients from our collective showed SDH gene mutations, one in SDHD and one in SDHB, respectively. Moreover, SDH activity detected in 5/8 patients confirmed the fact that SDH inactivation is not a major event in sporadic paragangliomas. LOH and FISH analysis demonstrated a frequent loss of regions within chromosome 11, indicating that additional genes in 11q may play a role in tumour genesis of sporadic paragangliomas.  (+info)

Radiation therapy for glomus tumors of the temporal bone. (7/24)

The treatment of glomic tumors has been controversial since its first description. It can be done with surgery, radiotherapy or just expectation. AIM: The objective of this paper was to evaluate the effectiveness and complications of radiotherapy. STUDY DESIGN: clinical with transversal cohort. MATERIAL AND METHOD: It was made a retrospective review in the charts of the patients with glomus jugulare tumors treated with radiotherapy. Disease control was determined by (1) no progression of symptoms or cranial nerve dysfunction or (2) no progression of the lesion in radiological follow-up. It was also evaluated the follow-up period and the sequelae of the treatment. RESULTS: Twelve patients were included, 8 of then women. The follow-up period was from 3 to 35 years, with a media of 11,6 years. The main symptoms were: hearing loss, pulsate tinnitus, dizziness and vertigo. The signs were pulsate retrotympanic mass, facial palsy and cofosis. The tumors were staged using Fisch's classification. The radiotherapy was performed with linear accelerator with dose ranging from 4500-5500 in 4-6 weeks. In the follow-up period were possible to identify sequelaes like dermatitis, meatal stenosis, cofosis and facial palsy. DISCUSSION: The signs and symptoms were the same found in the medical literature. The type and dosages of the radiotherapy were also the same of others reports. All patients had improvement of the symptoms and only one was not considered as having disease controlled. Complications were, in general, minor complications, with exception of the cofosis and facial palsy. CONCLUSION: Radiotherapy is a viable alternative to treatment of these tumors because their good response and low level of complications. It should be considered specially in advanced tumors where a surgical procedure could bring a high level of morbidity.  (+info)

Reduced quality of life in patients with head-and-neck paragangliomas. (8/24)

 (+info)

A Glomus Jugulare Tumor is a rare, usually benign, slow-growing tumor that develops from the glomus body, a small collection of modified blood vessels involved in temperature regulation, located near the jugular bulb in the skull. This type of tumor can cause symptoms such as hearing loss, pulsatile tinnitus (a rhythmic sound in the ear), and cranial nerve palsies due to its proximity to critical structures in the head and neck. Treatment typically involves surgical removal or radiation therapy.

Glomus jugulare is a small, highly vascular tumor that originates from the glomus body, which is a type of nerve ending involved in temperature regulation, located near the jugular bulb in the skull. These tumors are typically benign but can cause serious symptoms due to their location and effects on surrounding structures. Symptoms may include hearing loss, pulsatile tinnitus (a rhythmic buzzing or whooshing sound in the ear), dizziness, and difficulty swallowing. Treatment options include surgical removal and radiation therapy.

The temporal bone is a paired bone that is located on each side of the skull, forming part of the lateral and inferior walls of the cranial cavity. It is one of the most complex bones in the human body and has several important structures associated with it. The main functions of the temporal bone include protecting the middle and inner ear, providing attachment for various muscles of the head and neck, and forming part of the base of the skull.

The temporal bone is divided into several parts, including the squamous part, the petrous part, the tympanic part, and the styloid process. The squamous part forms the lateral portion of the temporal bone and articulates with the parietal bone. The petrous part is the most medial and superior portion of the temporal bone and contains the inner ear and the semicircular canals. The tympanic part forms the lower and anterior portions of the temporal bone and includes the external auditory meatus or ear canal. The styloid process is a long, slender projection that extends downward from the inferior aspect of the temporal bone and serves as an attachment site for various muscles and ligaments.

The temporal bone plays a crucial role in hearing and balance, as it contains the structures of the middle and inner ear, including the oval window, round window, cochlea, vestibule, and semicircular canals. The stapes bone, one of the three bones in the middle ear, is entirely encased within the petrous portion of the temporal bone. Additionally, the temporal bone contains important structures for facial expression and sensation, including the facial nerve, which exits the skull through the stylomastoid foramen, a small opening in the temporal bone.

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.

Goosecoid protein is not a term that has a specific medical definition. However, it is a biological term related to the field of developmental biology and genetics.

Goosecoid protein is a transcription factor that plays a crucial role in embryonic development, particularly during gastrulation - an early stage of embryogenesis where the three germ layers (ectoderm, mesoderm, and endoderm) are formed. The goosecoid gene encodes this protein, and it is primarily expressed in the Spemann-Mangold organizer, a structure located in the dorsal blastopore lip of amphibian embryos. This organizer region is essential for establishing the body axis and inducing the formation of the central nervous system.

In humans, goosecoid protein homologs have been identified, and they are involved in various developmental processes, including limb development and craniofacial morphogenesis. Dysregulation of goosecoid protein expression or function has been implicated in several congenital disorders and cancer types. However, a direct medical definition focusing on 'Goosecoid Protein' is not available due to its broader biological context.

The tympanic membrane, also known as the eardrum, is a thin, cone-shaped membrane that separates the external auditory canal from the middle ear. It serves to transmit sound vibrations from the air to the inner ear, where they are converted into electrical signals that can be interpreted by the brain as sound. The tympanic membrane is composed of three layers: an outer layer of skin, a middle layer of connective tissue, and an inner layer of mucous membrane. It is held in place by several small bones and muscles and is highly sensitive to changes in pressure.

The hyoid bone is a U-shaped bone located in the anterior neck, superior to the thyroid cartilage. It does not articulate with any other bones and serves as an attachment point for various muscles, including those involved in swallowing, breathing, and speaking. The unique structure of the hyoid bone allows it to support the tongue and contribute to the stability of the airway.

The Circle of Willis is a circulatory arrangement in the brain where the major arteries that supply blood to the brain converge to form an almost circular structure. It is named after Thomas Willis, an English physician who first described it in 1664.

This circle is formed by the joining of the two internal carotid arteries, which divide into the anterior cerebral and middle cerebral arteries, with the basilar artery, which arises from the vertebral arteries. These vessels anastomose, or connect, to form a polygon-like structure at the base of the brain.

The Circle of Willis plays a crucial role in maintaining adequate blood flow to the brain, as it allows for collateral circulation. If one of the arteries that make up the circle becomes blocked or narrowed, blood can still reach the affected area through the other vessels in the circle. This helps to minimize the risk of stroke and other neurological disorders.

The glossopharyngeal nerve (cranial nerve IX) is a mixed nerve that provides both sensory and motor functions to the posterior third of the tongue, the pharynx, the middle ear, and parts of the palate and neck. Glossopharyngeal nerve injuries refer to damages or trauma to this nerve, which can result in various symptoms:

1. Ipsilateral loss of taste sensation on the posterior one-third of the tongue.
2. Difficulty swallowing (dysphagia) and speaking due to paralysis of the associated muscles.
3. Reduced sensitivity to touch, pressure, and temperature in the affected areas.
4. Impaired or absent gag reflex on the side of the injury.
5. Pain in the ear (otalgia), throat, or neck.
6. Hoarseness or weak voice due to vocal cord paralysis.

Glossopharyngeal nerve injuries can occur due to various reasons, such as trauma, tumors, surgical complications, or neurological disorders like multiple sclerosis and stroke. Proper diagnosis and management of these injuries require a thorough examination by a healthcare professional, often involving a detailed clinical evaluation and imaging studies.

It is produced by the U.S. National Library of Medicine, the world's largest medical library, and is widely recognized as a trusted source of health information.

MedlinePlus offers information on various health topics, including conditions, diseases, tests, treatments, and wellness. It also provides access to drug information, medical dictionary, and encyclopedia, as well as links to clinical trials, medical news, and patient organizations. The website is available in both English and Spanish and can be accessed for free.

Head and neck neoplasms refer to abnormal growths or tumors in the head and neck region, which can be benign (non-cancerous) or malignant (cancerous). These tumors can develop in various sites, including the oral cavity, nasopharynx, oropharynx, larynx, hypopharynx, paranasal sinuses, salivary glands, and thyroid gland.

Benign neoplasms are slow-growing and generally do not spread to other parts of the body. However, they can still cause problems if they grow large enough to press on surrounding tissues or structures. Malignant neoplasms, on the other hand, can invade nearby tissues and organs and may also metastasize (spread) to other parts of the body.

Head and neck neoplasms can have various symptoms depending on their location and size. Common symptoms include difficulty swallowing, speaking, or breathing; pain in the mouth, throat, or ears; persistent coughing or hoarseness; and swelling or lumps in the neck or face. Early detection and treatment of head and neck neoplasms are crucial for improving outcomes and reducing the risk of complications.

Salivary glands are exocrine glands that produce saliva, which is secreted into the oral cavity to keep the mouth and throat moist, aid in digestion by initiating food breakdown, and help maintain dental health. There are three major pairs of salivary glands: the parotid glands located in the cheeks, the submandibular glands found beneath the jaw, and the sublingual glands situated under the tongue. Additionally, there are numerous minor salivary glands distributed throughout the oral cavity lining. These glands release their secretions through a system of ducts into the mouth.

Lymph nodes are small, bean-shaped organs that are part of the immune system. They are found throughout the body, especially in the neck, armpits, groin, and abdomen. Lymph nodes filter lymph fluid, which carries waste and unwanted substances such as bacteria, viruses, and cancer cells. They contain white blood cells called lymphocytes that help fight infections and diseases by attacking and destroying the harmful substances found in the lymph fluid. When an infection or disease is present, lymph nodes may swell due to the increased number of immune cells and fluid accumulation as they work to fight off the invaders.

In medical terms, the "neck" is defined as the portion of the body that extends from the skull/head to the thorax or chest region. It contains 7 cervical vertebrae, muscles, nerves, blood vessels, lymphatic vessels, and glands (such as the thyroid gland). The neck is responsible for supporting the head, allowing its movement in various directions, and housing vital structures that enable functions like respiration and circulation.

I'm sorry for any confusion, but "Gross Domestic Product" (GDP) is an economic term, not a medical one. GDP is the total monetary or market value of all the finished goods and services produced within a country's borders in a specific time period. It serves as a comprehensive measure of a nation’s overall economic activity.

If you have any medical questions or terms you would like defined, I would be happy to help!

In medical terms, the "head" is the uppermost part of the human body that contains the brain, skull, face, eyes, nose, mouth, and ears. It is connected to the rest of the body by the neck and is responsible for many vital functions such as sight, hearing, smell, taste, touch, and thought processing. The head also plays a crucial role in maintaining balance, speech, and eating.
