tuberous sclerosis wiki

[34] Cardiac failure due to rhabdomyomas is a risk in the fetus or neonate but is rarely a problem subsequently. tuberous sclerosis (uncountable) A rare disease that causes benign tumors to grow in the human brain, kidneys, heart, liver, eyes, lungs and skin, caused by a mutation in the genes for the tumor growth suppressor proteins hamartin and tuberin. The good news is that doctors can help you with each TSC concern, every step of the way. Current genetic tests have difficulty locating the mutation in roughly 20% of individuals diagnosed with the disease. Tuberous Sclerosis Complex is a genetic disorder that causes non-malignant tumors to form in many different organs, primarily in the brain, eyes, heart, kidney, skin and lungs. Cells from individuals with pathogenic mutations in the TSC2 gene display abnormal accumulation of glycogen that is associated with depletion of lysosomes and autophagic impairment. Tuberous sclerosis is a group of two genetic disorders that affect the skin, brain/nervous system, kidneys, and heart, and cause tumors to grow. The disease as presently understood was first fully described by Gomez (1979). Evidence of. Tuberous sclerosis complex (TSC) can cause benign tumors in different places in your body at different times in your life. NICE Guidance. Gesteelde, goedaardige, tumortjes die langs de nagels groeien. Tuberous sclerosis On the Web Most recent articles. Belgische belangenvereniging be-TSC VZW (betsc.be). De ernst van de ziekte kan sterk variëren van persoon tot persoon. This means you get tumors in lots of places in your body. [2] These proteins act as tumor growth suppressors, agents that regulate cell proliferation and differentiation. www.geneclinics.org; Notes . Rhabdomyoma vary in size from a few millimetres to several centimetres, and are usually found in the lower chambers (ventricles) and less often in the upper chambers (atria). Signs and symptoms vary widely, depending on where the growths develop and how severely a person is affected.Tuberous sclerosis is often detected during infancy or childhood. The history of tuberous sclerosis (TSC) research spans less than 200 years. The tuberous sclerosis complex. TSC is one of the most common genetic causes of autism spectrum disorder, which affects nearly half of people with TSC. Between 1 in 10 and 1 in 4 of individuals with TSC have no mutation that can be identified. TSC affects tissues from different germ layers. Crino PB, Nathanson KL, Henske EP. neurogliosis gangliocellularis diffusa[4], tubereuzesclerosecomplex[3] TSC is a rare, multi-system genetic disease that can cause benign tumours to grow on the brain or other vital organs such as the kidneys, heart, eyes, lungs, and skin. The term is used to describe the “association of a vascular nevus with an extensive pigmentary nevus”. TSC1 and TSC2 are both tumor suppressor genes that function according to Knudson's "two hit" hypothesis. These may block the circulation of cerebrospinal fluid around the brain, leading to hydrocephalus. These are rare tumours that can occur in any part of the human body. Northrup H, and Au KS. In Nederland zijn er ongeveer 2000 patiënten met tubereuze sclerose. Patients with TSC can develop progressive replacement of the lung parenchyma with multiple cysts, known as lymphangioleiomyomatosis (LAM). De hersenen en de nieren kunnen worden afgebeeld met MRI-scan, CT-scan, Echografie, Röntgenonderzoek, EEG of Wood's lamp onderzoek. Bij kinderen met een ernstige vorm van epilepsie kan vigabatrine effectief zijn. [9][10][11][12] Echter, nader onderzoek zal nodig zijn, voordat sirolimus op grote schaal kan worden ingezet voor de behandeling van TS. Tuberous sclerosis complex (TSC) is a rare genetic disorder with an incidence of 1:6000 live births and estimated prevalence of 50,000 individuals in the United States. Nonretinal lesions associated with TSC include: Pancreatic neuroendocrine tumours have been described in rare cases of TSC. Tuberous sclerosis complex consensus conference: Revised clinical diagnostic criteria. [5]. [22], The mTOR inhibitor everolimus was approved in the US for treatment of TSC-related tumors in the brain (subependymal giant cell astrocytoma) in 2010 and in the kidneys (renal angiomyolipoma) in 2012. The defective degradation of glycogen by the autophagy-lysosome pathway is, at least in part, independent of impaired regulation of mTORC1 and is restored, in cultured cells, by the combined use of PKB/Akt and mTORC1 pharmacological inhibitors. [2]. Should angiomyolipoma bleed, this is best treated with, Repeat chest HRCT in adult women every five to 10 years. [18] However, the difference is subtle and cannot be used to identify the mutation clinically. In adult women, test pulmonary function and perform a. Some people with tuberous sclerosis have such mild signs and symptoms t… Subependymal giant cell astrocytoma is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. Angiomyolipomas are found in about one in 300 people without TSC. However, some mutations are less clear in their effect, and so not sufficient alone for diagnosis. Tubereuze sclerose[6][3] (TS), ook wel de ziekte van Bourneville-Pringle[7][3] genoemd, is een erfelijk syndroom dat gepaard kan gaan met afwijkingen van de huid, de hersenen, de nieren en andere organen. This has led to human trials of rapamycin as a drug to treat several of the tumors associated with TSC. [13], TSC first came to medical attention when dermatologists described the distinctive facial rash (1835 and 1850). De enige veilige behandeling is "embolisatie"; het afsluiten van het bloedvat waardoor de tumor wegschrompelt. A 12-lead ECG should be performed every three to five years. Much research has also been conducted on everolimus and other mTOR inhibitors as targeted therapy for use in a number of cancers. Tuberous sclerosis: CT findings and differential diagnosis. Onder de trias van Bourneville verstaat men de combinatie van een verstandelijke beperking, epilepsie en adenoma sebaceum. However, 2% may also have autosomal dominant polycystic kidney disease. Once a particular mutation is identified in someone with TSC, this mutation can be used to make confident diagnoses in other family members. Phakomatoses, or phacomatosis pigmentovascularis (PPV), is the term used for a group of rare syndromes involving structures arising from the embryonic ectoderm. [ citation needed ]. US National Guidelines Clearinghouse. Hamartin and tuberin function as a complex which is involved in the control of cell growth and cell division. In children and adults younger than 25 years, a magnetic resonance imaging (MRI) of the brain is performed every one to three years to monitor for subependymal giant cell astrocytoma (SEGA). Tuberous sclerosis (TSC) is a genetic disorder caused by mutations on either of two genes TSC1 and TSC2. Therefore, several signs are considered together, classed as either major or minor features. Despite this, many hamartomas are found to have clonal chromosomal aberrations that are acquired through somatic mutations, and on this basis the term hamartoma is sometimes considered synonymous with neoplasm. So, close follow up for the mental development and early control of seizures are recommended in a trial to reduce the risk factors of poor outcome. Although benign, an angiomyolipoma larger than 4 cm is at risk for a potentially catastrophic hemorrhage either spontaneously or with minimal trauma. Tuberous sclerosis (TSC) is a genetic disorder. These nodules have a tendency to calcify as the patient ages. It is encoded by the Folliculin (FLCN) gene that acts as a tumor suppressor gene. Powerpoint slides. Signs and symptoms of tuberous sclerosis complex (TSC) can affect how your body works, including how you feel, how your skin looks, how you think, and how you act. The enlarged area of the root-tuber, or storage root, can be produced at the end or middle of a root or involve the entire root. Children undergo a baseline electroencephalograph (EEG) and family educated to identify seizures if/when they occur. van den (2012). The neurologist Vogt (1908) established a diagnostic triad of epilepsy, idiocy, and adenoma sebaceum (an obsolete term for facial angiofibroma). A benign tumor is a mass of cells (tumor) that lacks the ability to either invade neighboring tissue or metastasize. [31] Facial angiofibromas can be reduced with laser treatment and the effectiveness of mTOR inhibitor topical treatment is being investigated. [6], The psychosocial impacts of TSC include low self-esteem and self-efficacy in the individual, and a burden on the family coping with a complex and unpredictable disorder. A tuberous root or storage root, is a modified lateral root, enlarged to function as a storage organ. The central nervous system lesions seen in this disorder include hamartomas of the cortex, hamartomas of the ventricular walls, and subependymal giant cell tumors, which typically develop in the vicinity of the foramina of Monro. Most cited articles. In suspected or newly diagnosed TSC, the following tests and procedures are recommended by 2012 International Tuberous Sclerosis Complex Consensus Conference. TAND can be investigated and considered at six levels: behavioural, psychiatric, intellectual, academic, neuropsychological, and psychosocial. N Engl J Med. A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. Lymphangioleiomyomatosis is only a risk for females with angiomyolipomas. Higher tubers numbers is associated with poor seizure outcome and autistic behavior. Unlike most benign tumors elsewhere in the body, benign brain tumors can be life-threatening.

One third of cases are inherited; the rest are new mutations. Ocular lesions include those of the eyelids which often appear in early childhood along with other facial angiofibromas (formerly called adenoma sebaceum). However, with appropriate medical care, most individuals with the disorder can look forward to normal life expectancy. Tuberous sclerosis (TSC) is a genetic disorder that causes the growth of benign tumors in different parts of the body, including the kidneys, skin, heart, lungs, eyes, or brain. Tuberous sclerosis is a lifelong condition that requires long-term care and support from a range of different healthcare professionals. MRI is superior to CT or ultrasound. It is most commonly associated with tuberous sclerosis complex (TSC). Sommige patiënten hebben geen of weinig symptomen, anderen zijn van kinds af aan ernstig gehandicapt. [1] The disease is often abbreviated to tuberous sclerosis, which refers to the hard swellings in the brains of patients, first described by French neurologist Désiré-Magloire Bourneville in 1880. It inhibits activation of T cells and B cells by reducing their sensitivity to interleukin-2 (IL-2) through mTOR inhibition. RCC most commonly occurs between 6th and 7th decade of life. Wienecke R, et al. The complex appears to interact with RHEB GTPase, thus sequestering it from activating mTOR signalling, part of the growth factor (insulin) signalling pathway. The specific function of this protein is unknown. Symptoms were periodically added to the clinical picture. Some cases may cause disfigurement, necessitating treatment. De ziekte erft autosomaal-dominant over, dat wil zeggen dat gemiddeld de helft van de kinderen van een ouder met tubereuze sclerose de aandoening zal hebben. An estimated 40-50 percent of individuals with TSC have autism spectrum disorder, making TSC … Birt–Hogg–Dubé syndrome (BHD), also Hornstein–Birt–Hogg–Dubé syndrome, Hornstein–Knickenberg syndrome, and fibrofolliculomas with trichodiscomas and acrochordons is a human autosomal dominant genetic disorder that can cause susceptibility to kidney cancer, renal and pulmonary cysts, and noncancerous tumors of the hair follicles, called fibrofolliculomas. [6], Behavioural problems most commonly seen include overactivity, impulsivity and sleeping difficulties. [ citation needed ], TSC occurs in all races and ethnic groups, and in both genders. Deze pagina is voor het laatst bewerkt op 10 feb 2017 om 23:09. De aandoening werd voorheen tot de facomatosen gerekend. Most cause no problems, but are helpful in diagnosis. The CT findings in a patient with tuberous sclerosis are described with … The incidenceis between 1/6,000 and 1/10,000. [3], Prognosis is highly variable and depends on the symptoms, but life expectancy is normal for many. It predominantly affects women, especially during childbearing years. It is characterized by visceral cysts and benign tumors with potential for subsequent malignant transformation. Originally regarded as a rare pathological curiosity, it is now an important focus of research into tumour formation and suppression. If only one major feature or at least two minor features are present, the diagnosis is only regarded as possibly TSC. The term sporadic LAM is used for patients with LAM not associated with tuberous sclerosis complex (TSC), while TSC-LAM refers to LAM that is associated with TSC. Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin. by a subependymal nodule in the region of the foramen of Monro) or idiopathic in nature. ; Mental retardation. The condition can also cause tumors to grow in … However, Bourneville (1880) is credited with having first characterized the disease, coining the name "tuberous sclerosis", thus earning the eponym Bourneville's disease. Estimates of the prevalence of TS range from as high as 1:6000 to 1:100,000 or lower. Perivascular epithelioid cell tumour, also known as PEComa or PEC tumour, is a family of mesenchymal tumours consisting of perivascular epithelioid cells (PECs). Academic issues occur even in people with TSC who have normal intellectual ability. Review articles. After 25 years, if there are no SEGAs then periodic scans may no longer be required. TSC has very strong association with Autism Spectrum Disorder and about 1-4% of autistic people experience Tuberous sclerosis. So far, it has been mapped to two genetic loci, TSC1 and TSC2 . GeneReviews. Infantile spasms and severely epileptogenic EEG patterns are related to the poor seizure outcome, poor intellectual capabilities and autistic behavior. [6]. [7], Small tumours of the heart muscle, called cardiac rhabdomyomas, are rare in the general population (perhaps 0.2% of children) but very common in people with TSC. Scan the abdomen for tumours in various organs, but most importantly angiomyolipomata in the kidneys. Phakomatoses, also known as neurocutaneous syndromes, are a broad group of congenital disorders that are characterized by hamartomatous lesions of the skin and the central and peripheral nervous systems. Recent genetic analysis has shown that the proliferative bronchiolar smooth muscle in TSC-related lymphangioleiomyomatosis is monoclonal metastasis from a coexisting renal angiomyolipoma. Few differences have yet been observed in the clinical phenotypes of patients with mutation of one gene or the other. Sirolimus, een oraal in te nemen geneesmiddel, (ook bekend onder de namen rapamycine en Rapamune®) grijpt hier op aan en normaliseert de activiteit van het verstoorde mTOR pathway. Een nieuwe niet-chirurgische behandelmethode dient zich aan. skin, eyes, and nervous system).. Most cases represent new (sporadic or de novo) gene mutations, with no family history of the disease. It is a type of phakomatosis that results from a mutation in the Von Hippel–Lindau tumor suppressor gene on chromosome 3p25.3. The live-birth prevalence is estimated to be between 10 and 16 cases per 100,000. An individual may also be diagnosed at any time as a result of genetic testing of family members of another affected person. The following table shows the prevalence of some of the clinical signs in individuals diagnosed with TSC. Benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated. [21]. https://nl.wikipedia.org/w/index.php?title=Tubereuze_sclerose&oldid=48577316, Wikipedia:Lokale afbeelding gelijk aan Wikidata, Creative Commons Naamsvermelding/Gelijk delen. Individuals with TSC may experience none or all of the clinical signs discussed above. Mueller RF. A magnetic resonance imaging (MRI) of the brain to identify tubers, subependymal nodules (SEN) and sub-ependymal giant cell astrocytomas (SEGA). Molecular genetic studies have defined at least two loci for TSC. A more complete case was presented by von Recklinghausen (1862), who identified heart and brain tumours in a newborn who had only briefly lived. (2003). De tekst is beschikbaar onder de licentie. They grow in size during the second half of pregnancy, but regress after birth, and are seen in only around 20% of children over two years old. Renal cell carcinoma is uncommon. Folliculin also known as FLCN, Birt-Hogg-Dubé syndrome protein or FLCN_HUMAN is a protein that in humans is associated with Birt-Hogg-Dubé syndrome and hereditary spontaneous pneumothorax. [11]. [6], Between 60 and 80% of TSC patients have benign tumors (once thought hamartomatous, but now considered true neoplasms) of the kidneys called angiomyolipomas frequently causing hematuria. Tuberous sclerosis proteins 1 and 2, also known as TSC1 (hamartin) and TSC2 (tuberin), form a protein-complex. [35] In the brain, the subependymal nodules occasionally degenerate to subependymal giant cell astrocytomas. [8]. Tuberous sclerosis, also known as tuberous sclerosis complex, is a rare genetic condition that causes mainly non-cancerous (benign) tumours to develop in different parts of the body. Around 80% of children under two-years-old with TSC have at least one rhabdomyoma, and about 90% of those will have several. About 90% of people with TSC develop a range of neurodevelopmental, behavioural, psychiatric, and psychosocial difficulties. Tuberous Sclerosis Complex 2 (TSC2), also known as Tuberin, is a protein that in humans is encoded by the TSC2 gene. Add new page. The encoding two genes are TSC1 and TSC2. The inheritance pattern is autosomal dominant. In TSC1, the abnormality is localized on chromosome 9q34, but the nature of the gene protein, called hamartin, remains unclear. These tumors are composed of vascular (angio–), smooth muscle (–myo–), and fat (–lip-) tissue. Sirolimus, also known as rapamycin, is a macrolide compound that is used to coat coronary stents, prevent organ transplant rejection and treat a rare lung disease called lymphangioleiomyomatosis. [9], For clinical diagnosis, there isn't one sign that is unique (pathognomonic) to TSC, nor are all signs seen in all individuals. These are characterised by vascular and pigmentary birthmarks or skin lesions, and often involving multiple organ systems in the body. These are often specific learning disorders such as dyscalculia (understanding mathematics), but also include other aspects affecting school life such as anxiety, lack of social skills or low self-esteem. For example, arrhythmia may cause fainting that is confused with drop seizures, and symptoms of arrhythmia such as palpitations may not be reported in an individual with developmental delay. [36]. Understand. "Tuberous Sclerosis Complex." A hamartoma is a mostly benign, local malformation of cells that resembles a neoplasm of local tissue but is usually due to an overgrowth of multiple aberrant cells, with a basis in a systemic genetic condition, rather than a growth descended from a single mutated cell (monoclonality), as would typically define a benign neoplasm/tumor. The information in this outline was last updated in 2001. Fibrofolliculomas are the most common manifestation, found on the face and upper trunk in over 80% of people with BHD over the age of 40. RCC occurrence shows a male predomiance over women with a ratio of 1.5:1. ziekte van Bourneville[5] Subependymal nodules are composed of abnormal, swollen glial cells and bizarre multinucleated cells which are indeterminate for glial or neuronal origin. ASD is more common in TSC2 than TSC1 and more common with earlier and more severe epilepsy, and with lower intellectual ability. [9], TSC can be first diagnosed at any stage of life. TSC is caused by a mutation of either of two genes, TSC1 and TSC2 , which code for the proteins hamartin and tuberin, respectively, with TSC2 mutations accounting for the majority and tending to cause more severe symptoms. Hence, awareness regarding different organ manifestations of TSC is important. Prenatal diagnosis is possible by chance if heart tumours are discovered during routine ultrasound. "Tuberous Sclerosis." [15] TSC2 encodes for the protein tuberin, is located on chromosome 16 p13.3, and was discovered in 1993. TopContent. Mutations in these genes can cause tuberous sclerosis complex. Gross deletions affecting both genes may account for the 2% of individuals with TSC who also develop polycystic kidney disease in childhood. Check renal (kidney) function annually. What Is Tuberous Sclerosis? [28], Neurosurgical intervention may reduce the severity and frequency of seizures in TSC patients. This explains why, despite its high penetrance, TSC has wide expressivity. An individual with two major features, or one major feature and at least two minor features can be given a definite diagnosis of TSC. Category:Tuberous sclerosis | Psychology Wiki | Fandom. Tuberous sclerosis, also tuberous sclerosis complex (abbreviated TSC), is an autosomal dominant syndrome associated with an increased risk of hamartomas and some risk increase for malignant tumours.. Geregeld wordt van hen een scan gemaakt, zodat tijdig kan worden ingegrepen als een hersentumor gevaar op gaat leveren, of de niertumoren te groot worden. Prior to the invention of CT scanning to identify the nodules and tubers in the brain, the prevalence was thought to be much lower, and the disease associated with those people diagnosed clinically with learning disability, seizures and facial angiofibroma. The complex is known as a tumor suppressor. Tuberous sclerosis, also known as tuberous sclerosis complex or Bourneville disease, is a neurocutaneous disorder (phakomatosis) characterised by the development of multiple benign tumours of the embryonic ectoderm (e.g. [6] Schizophrenia (and symptoms like hallucinations or psychosis) is no more common in TSC than the general population. Tuberous sclerosis has an incidence of 1:6000-12,000, with most being sporadic (see below) . Tuberous Sclerosis Alliance. [ citation needed ]. In many cases, the tumors cause no symptoms or the symptoms are so mild as to not cause the patient any impairment. Therefore, diagnostic criteria have been developed to aid the diagnosis of tuberous sclerosis. 2006;355:1345-56. "My Child has Tuberous Sclerosis: A Brochure for Parents." These difficulties are less frequently identified and thus undertreated when compared with the neurological symptoms. Astrocytic hamartomas can calcify, and they are in the differential diagnosis of a calcified globe mass on a CT scan. Differential Diagnosis . In infancy, epilepsy, particularly infantile spasms, or developmental delay may lead to neurological tests. On magnetic resonance imaging (MRI), TSC patients can exhibit other signs consistent with abnormal neuron migration such as radial white matter tracts hyperintense on T2WI and heterotopic gray matter. Cutaneous and visceral lesions may occur, including angiofibroma, cardiac rhabdomyomas, and renal angiomyolipomas. TSC is caused by mutations on either of two genes, TSC1 and TSC2, which encode for the proteins hamartin and tuberin respectively. Tuberous sclerosis results from alterations (mutations) in a gene or genes that may occur spontaneously (sporadically) for unknown reasons or be inherited as an autosomal dominant trait. [10] [14] Two-thirds of TSC cases result from sporadic genetic mutations, not inheritance, but their offspring may inherit it from them. Management of Genetic Syndromes (2001): 437-457. Less common are depressed mood, self-injury, and obsessional behaviours. Tubereuze sclerose (TS), ook wel de ziekte van Bourneville-Pringle genoemd, is een erfelijk syndroom dat gepaard kan gaan met afwijkingen van de huid, de hersenen, de nieren en andere organen. Later, he expanded the list t… Angiomyolipomas are the most common benign tumour of the kidney. [23] [24]   Oral everolimus (rapalog) reduces tumour size, is effective in terms of response to skin lesions and does not increase the risk of adverse events. Tuberous sclerosis was classically described as presenting in childhood with a triad (Vogt triad) of: 1. seizures: absent in one-quarter of individuals 2. intellectual disability: up to half have normal intelligence 3. adenoma sebaceum: only present in about three-quarters of patients1 The full triad is only seen in a minority of patients (~30%). In TSC2, the gene abnormalities are on chromosome 16p13. morbus Bourneville-Pringle[2] People with TSC are frequently also diagnosed psychiatric disorders: autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), anxiety disorder and depressive disorder. Repeat MRI of abdomen every one to three years throughout life. Repeat screening for TSC-associated neuropsychiatric disorders (TAND) at least annually. Those individuals with mild symptoms generally do well and live long, productive lives, while individuals with the more severe form may have serious disabilities. Examine the skin under a Wood's lamp (hypomelanotic macules), the fingers and toes (ungual fibroma), the face (angiofibromas), and the mouth (dental pits and gingival fibromas). However, the signs, symptoms and methods used to confirm a … Tuberous sclerosis affects as many as 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. It predisposes for renal cell cancer, an association denominated hereditary leiomyomatosis and renal cell cancer, and it is also associated with increased risk of uterine leiomyosarcoma. Tuberous sclerosis is a genetic multisystem disorder characterised by widespread hamartomas in several organs, including the brain, heart, skin, eyes, kidney, lung, and liver. Fibrous cephalic plaques are present in about 25% of people with TSC. Many studies have examined whether early onset, type and severity of epilepsy associates with intellectual ability. [33]. Estimates of the proportion of TSC caused by TSC2 range from 55% to 90%. Veel Nederlandse patiënten zijn in Utrecht of in bij het Expertisecentrum ENCORE in Rotterdam onder controle van de speciale polikliniek. Take blood pressure and test renal function. De met TS geassocieerde tumoren vertonen een verhoogde activiteit van het zogenaamde mTOR pathway. No missense mutations occur in TSC1. Tuberous sclerosis (TWO-bur-uhs skluh-ROH-sis), also called tuberous sclerosis complex, is an uncommon genetic disorder that causes noncancerous (benign) tumors — unexpected overgrowths of normal tissue — to develop in many parts of the body. Cases of TSC-related lymphangioleiomyomatosis recurring following lung transplant have been reported. Rhabdomyomas are believed to be responsible for the development of heart arrhythmia later in life, which is relatively common in TSC. De behandeling is vooral symptoombestrijding: behandeling van de epilepsie bijvoorbeeld. 2017, the various symptoms and complications from TSC may experience none or of.
