Cherubism is a rare genetic disorder that causes prominence in the lower portion in the face. The name is derived from the temporary chubby-cheeked resemblance to putti, often confused with cherubs, in Renaissance paintings. The appearance of people with the disorder is caused by a loss of bone in the mandible which the body replaces with excessive amounts of fibrous tissue. In most cases, the condition fades as the child grows, but in a few even rarer cases the condition continues to deform the affected persons face. Cherubism also causes premature loss of the primary teeth and uneruption of the permanent teeth. The condition Cherubism is a rare autosomal dominant disease of the maxilla and mandible. Approximately 200 cases have been reported by medical journals with the majority being males. Cherubism is usually first diagnosed around age 7 and continues through puberty and may or may not continue to advance with age. The degrees of Cherubism vary from mild to severe. Osteoclastic and ...
surrounding the eye socket) causes the eyeball to tip upward. The name of the condition is derived from cherub (angelic looking, as depicted in Renaissance paintings).. The medical community currently believes that the condition develops when a gene that governs the function of cells that buildup bone (osteoblasts) and breakdown bone (osteoclasts) works in an atypical manner. Usually osteoblasts and osteoclasts build up and breakdown bone in a balanced way, so that the strength of bone is maintained. Persons with the genetic make up of cherubism appear to breakdown bone at an increased rate and to build it up in an atypical way (through large multinucleated cells). The imbalanced osteoblast and osteoclast activity appears to lead to the formation of fibrous tissue, which appears as bubbles or spongy in radiographs. The lesions of cherubism are graded into levels indicating the involvement of the mandible and/or maxilla, the resorption of the roots of teeth, and the involvement of the ...
Discussion. Cherubism results from replacement of bone with multilocular cysts due to osteoblasts and osteoclasts malfunctioning (Figs. 2 and 3, Supplementary Material). As already mentioned it represent a benign fibro-osseous pathology and it should be distinguished from central giant cell granuloma (CGCG), multiple giant-cell lesion syndrome, fibrous dysplasia, brown tumors and Ramon syndrome and hyperparathyroidism.6 Differential diagnosis is based on specific clinical, radiological and anatomo-pathological features.. Although the severity of pathology, no effective treatment exists. Therapy strategies include: (a) surgical treatment; (b) medical treatment.. In relation to surgery, the strategy of wait and see is the most commonly used in these patients (Table 1, Supplementary Material). Surgery before puberty is only recommended in case of serious deformity or severe psychological impact.7. In relation to medical treatment, there is no evidence for an effective medical treatment. Recently, ...

Cherubism is a rare benign (non-neoplastic) hereditary condition of childhood, which is inherited as an autosomal dominant trait and is characterized by bilateral expansion of the mandible, maxilla or both. Giving them a characteristic cherubic appearance. The treatment of cherubism is still controversial and is said that the disease regresses itself and after regressing if any asymmetry is left then the bony deformity can be corrected by decortications of bone and osseous shaving. This article reviews the recent development in the literature of cherubism ...
Cherubism is a rare genetic disorder of the jaw characterized by bilateral, symmetrical enlargement of the mandible and/or maxilla resulting from rapid bone degradation followed by extensive bone remodeling with multilocular benign cysts. As a consequence, the skin is stretched over the classically swollen cheeks, pulling the lower eyelids down and exposing a line of sclera so that the eyes appear to be raised heavenward. This facial appearance of the upwardly turning eyes and swollen cheeks has been described as resembling the faces of cherubs found in Renaissance art. The variable cherubism phenotype can range from absence of any clinical features to severe mandibular and maxillary overgrowth causing respiratory, vision, speech, and swallowing concerns. Typical age of onset is 2 to 5 years, with the jaw lesions progressing gradually until puberty when the swelling spontaneously stabilizes and then regresses. Residual radiographic changes can last into the fourth decade. Associated dental ...
Patients may look normal in the first years of life. The initial changes are characterized by unilateral fullness of the cheeks, most often starting during the second or third year of life (but later onset is possible). Eventually, both mandibular rami and angles are involved, along with the maxilla. The growth rate is fastest during the first 2 years, then slows down and finally regresses during puberty. Hypertelorism is a constant sign. There is also an association with hyperplasia of cervical lymph nodes. The teeth are often loose and irregularly positioned. Extragnathic skeletal involvement is rare. Conservative management is recommended because it is a benign, self-limited condition. However, curettage of tissue hindering nasal breathing or function of the tongue may be indicated. Surgery may be requested for cosmetic reasons. Patients are mentally normal. ...

Small business owners take note, with the Section 179 deduction small companies save big! Business owners who acquire equipment for their business, including medical equipment including EKG machines and spirometers, can elect for a section 179 tax saving.. This tax saving allows a small business to obtain an enhanced deduction in a single tax year, rather than a little at a time over a number of years. This deduction is known by its section in the tax code: a section 179 deduction.. Under this section, businesses that spend less than $2,000,000 a year on qualified equipment may write off up to $500,000. Because this section is designed to benefit small companies, this deduction phases out dollar for dollar when a business purchases more than $2,000,000 in one year.. For more information or to purchase medical equipment, call 877-646-3300 or visit Medical Device Depot.. ...

Giant cell lesions are locally aggressive intraosseous neoplasms with capacity to metastasize. The role of immune surveillance in the pathophysiology of giant cell lesions is poorly understood, and understanding what role the immune system plays in giant cell lesions may lead to the development of more effective treatment. The aim of this study was to explore the role of immune surveillance in giant cell lesions by examining the expression of the HLA class I and class II antigens and tumor infiltrating lymphocytes. In addition, we examined the role of the immune modulating surface antigen B7-H3, which belongs to the B7 superfamily, a group of molecules that modulates T-cell responses.. ...

This paper has two parts. In the first part, I demonstrate that, in the absence of price and wage bounds, monetary models do not have current equilibria - and so lack predictive content - for a wide range of possible policy rules and/or beliefs about future equilibrium outcomes. This non-existence problem disappears in models in which firms face (arbitrarily loose) finite upper bounds on prices or positive lower bonds on nominal wages. In the second part, I study the properties of a class of dynamic monetary models with these kinds of bounds on prices/wages. Among other results, I show that these models imply that the Phillips curve is L-shaped, are consistent with the existence of permanently inefficiently low output (secular stagnation), and do not imply that forward guidance is surprisingly effective. I show too that economies with lower nominal wage floors have even worse equilibrium outcomes in welfare terms. It follows that models with arbitrarily low but positive nominal wage floors are ...
The central giant cell granuloma is felt to be a benign lesion that only occurs in the jaws, though similar lesions occur in the fingers and toes. Its relationship to the giant cell tumor of the long bones is unknown, but it is felt that the giant cell tumor represents a more aggressive and possibly malignant lesion that rarely occurs in the jaws, if at all. Other authorities feel that these lesions represent a spectrum of disease from malignant to very benign. Central giant cell granulomas normally occur in the anterior part of the jaws (in areas where deciduous teeth were present) and normally occur in the second and third decades, although they have been noted in all decades of life. Histologically similar, or even identical, appearances may occur in hyperparathyroidism, cherubism, and aneurysmal bone cysts, which should normally be ruled out prior to establishing the diagnosis. When the central giant cell granuloma was first identified as a distinct lesion (previously, it had been included ...
Central giant cell granuloma (CGCG) is a benign intraosseous lesion predominantly involving the mandible in young females. Exact etiology of this lesion is controversial and remains unknown. However, three competing theories are prevailing which states that it could be a reactive lesion, a developmental anomaly or a benign neoplasm. CGCG has been grouped into non-aggressive and aggressive variants on the basis of clinical, radiographic and histopathologic features. This paper reported a case of 29 year old female patient, presented with complain of pain and swelling in right vestibule region for one and half month. Based on clinicoradiologic findings, provisional diagnosis of aggressive CGCG was given and the lesion was surgically intervened. Histopathological report revealed central giant cell granuloma. The healing was uneventful and no complication noted till date. The purpose of this article is to review the clinical, radiological, histopathological features and management of aggressive CGCG ...
This report suggests that early exfoliation of primary teeth can be a side effect of bone resorption in patients with CAH. Early exfoliation of the primary dentition and bone loss is an uncommon finding in children. However, whenever it occurs is important to diagnose the patient early because it is usually correlated with serious systematic diseases.18. Premature loss of primary teeth has not been reported in the past in a case of CAH. However, CAH should be included in the differential diagnosis of premature loss of teeth because disturbance in dental development may be the first symptom of this disorder.13 Other systematic diseases that may cause premature exfoliation of teeth include hypophosphatasia, aggressive periodontitis, Papillon-Lefèvre syndrome, Singleton-Merten syndrome, Hajdu-Cheney syndrome immunodeficiency (neutropenia, leukocyte adhesion deficiency, leukemia), Langerhans histocytosis, diabetes mellitus, hyperthyroidism, cherubism, dentinal dysplasia, Ehlers-Danlos syndrome, ...

Central giant cell granuloma adalah lesi intraosseus yang jinak atau benignan. CGCG merupakan lesi pada tulang yang jarang terjadi dan bersifat asimptomatik serta berkembang lambat. Namun lesi ini dapat juga berkembang menjadi ganas atau malignan. Pada pemeriksaan klinis dan radiografi, lesi CGCG sering salah didiagnosa. Pada gambaran radiografi, lesi CGCG terlihat sebagai gambaran radiolusen dan tedapat gambaran yang berwarna opak (wispy) yang menutupi lesi tersebut. Diagnosa yang akurat diperoleh melalui pemeriksaan histopatologi. Maka dengan pemeriksaan histopatologis Terlihat adanya giant cell dengan inti sel 5-20 yang memiliki vakuola dan terdapat jaringan mesenkim yang berbentuk spindel serta oval. Perawatan lesi ini biasanya dengan kuretase lokal, walaupun dapat menyebabkan rekuren jika tidak bersih. CGCG adalah lesi intraosseous yang jinak yang sering terjadi pada usia muda, khususnya pada wanita ...
19 cases of central giant cell granuloma (CGCG) were reviewed after screening the records of the past four years of the Dental out patient department of AIIMS Hospital, New Delhi. It was found that CGCG usually occurs in the 2nd and 3rd decades and is more common in females. The mandible is more frequently involved than the maxilla and lesions occur more commonly on the right than left side.
