Background: Geographic tongue is an inflammatory disorder of unknown etiology that affects the epithelium of the tongue. It has been associated with several cutaneous diseases. Objective: To determine the prevalence of geographic tongue and its association with other cutaneous diseases in patients referred to the dermatology clinic of Razi hospital. Patients and methods: A cross-sectional study...

geographic tongue is a benign disorder involving the dorsal surface of the tongue characterized by depapillated areas with leading and folded edges in yellowish or grayish white color and sometimes with unclear borders. many studies have reported a relationship between such condition and different risk factors. this study aimed to investigate the prevalence rate and the risk factors of geograph...

This paper deals with the design and performance analysis of centrifugal pump. In this paper, centrifugal pump is analyzed by using a single-stage end suction centrifugal pump. Two main components of a centrifugal pump are the impeller and the casing. The impeller is a rotating component and the casing is a stationary component. In centrifugal pump, water enters axially through the impeller eye...

The flow in a double-suction twin-volute five-stage centrifugal pump is studied numerically using Computational Fluid Dynamics (CFD) calculations. performance at various rates obtained are compared with the theoretically results. deterioration were investigated to find losses associated design of components. stage-wise analysis revealed hydraulic second-stage impeller due highly swirled exiting...

background and objectives: squamous cell carcinoma of the tongue (sccot) is the most common malignant neoplasm in oral cavity. at the time of the diagnosis of sccot regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. although the level of healthcare has significantly improved, the survival rate is still low with an un...

granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

Background and Aim: Benign migratory glossitis, or geographic tongue, is usually an asymptomatic inflammatory disorder of unknown etiology that affects the epithelium of the tongue. Among the etiologic factors proposed, emotional causes were suspected by several investigators. The objective of this study was to evaluate the anxiety and cortisol level in patients with geographic tongue compared ...
