myoepitheliomas are benign tumors which account for less than 1% of all salivary gland tumors. in this article, we report the clinical, pathologic, and immunohistochemical features of plasmacytoid myoepithelioma of the hard palate in a 73-year-old man having a painless hard palate mass with progressive growth for one month who was admitted in alzahra hospital of isfahan university of medical sc...

introduction: cleft lip (cl) and cleft palate (cp) are among the most common congenital anomalies. constituting 65% of head and neck anomalies in isolated or syndromic forms, they are considered as the most common head and neck congenital deformities in children. methods: 15 children from the tabriz children hospital were evaluated in this descriptive-analytic cross sectional study that possess...

introduction: cleft lip and palate are among the most common congenital anomalies worldwide. this study was conducted in order to explore the incidence and related factors of cleft lip and/or palate (cl/p) among live births in mashhad, north-eastern iran.   materials and methods: in this cross-sectional study, records of 28,519 infants born between march 1982 and march 2011 at three major hospi...

results no significant difference was found between the groups regarding bmht rs3797546 gene polymorphism. the c allele was not associated with ns-cl/p (or = 1.27, 95% ci = 0.85-2.79, p = 0.690). conclusions our data suggested that bmht rs3797546 gene polymorphism was not associated with risk/ protection for ns-cl/p in a sample of iranian population. larger studies are required to validate our ...

Background & Objectives: The levator veli palatini (LVP) muscle is most commonly reported as the most abnormal muscle in the population with cleft palate and the muscle plays a significant role in velar elevation, and therefore speech production. Methods: This article reviewed the literature focusing on anatomic aspects of the LVP muscle in normal and cleft palate populations and addressed the ...

A two-way tactile communication system incorporating oral-based tactile modes is developed. The prototype system allows the user to both receive navigation cues, via a microfabricated flexible electrotactile palate display, and transmit information to the outside environment using a tongue operated device (TOD). The palate display consists of a flexible electrocutaneous-mode 7x7 electrode array...

Cocaine abuse occasionally causes extensive destruction of the osteocartilaginous structures of the nose, sinuses and palate, which mimics the clinical picture of other diseases associated with necrotising midfacial lesions. The differentiation of cocaine-induced midline destructive lesions (CIMDL) and limited granulomatosis with polyangiitis (GPA) may be difficult, particularly if patients do ...

OBJECTIVE The objective of this study was to improve and evaluate cleft lip/palate face models to give support information to the parents whose children have cleft lip/palate. MATERIAL AND METHOD Cleft lip/palate face models are made from a mold of about the same size as a child'head using rubber, wood and silicone and can be separated into parts to match the severity of the disease. The auth...

One of the most frequent congenital malformations is cleft lip and/or palate. The above-mentioned defect is a serious medical and social problem, and knowledge concerning its incidence pictures the scale of this phenomenon. the aim of the study was to determine the prevalence of cleft lip and/or palate in children in Łódź during the period between 2001 and 2010. Material and methods. We were ab...

We have identified a role for two evolutionarily related, secreted metalloproteases of the ADAMTS family, ADAMTS20 and ADAMTS9, in palatogenesis. Adamts20 mutations cause the mouse white-spotting mutant belted (bt), whereas Adamts9 is essential for survival beyond 7.5 days gestation (E7.5). Functional overlap of Adamts9 with Adamts20 was identified using Adamts9(+/-);bt/bt mice, which have a fu...
