purpose : granular cell tumors (gct) are benign unusual neoplasms which have been proven to have a schwann cell phenotype. they rarely occur in the eye region. case reports : we report three cases of gct in the ocular adnexa including palpebra, subconjuctiva and orbit which rarely occur. patients are, a young girl with the lesion in orbit and presentation of proptosis, a middle aged man with th...

tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...

statement of problem: failure of endodontic treatment is determined on the basis of radiographic findings and clinical signs and/ or symptoms of the treated teeth. purpose: the purpose of this study was to determine endodontic treatment failure in relation to various factors influencing it in teeth with periapical lesions (clinically and radiographically). materials and methods: teeth which had...

introduction: chronic sclerosing sialadenitis is a relatively uncommon disorder of the salivary gland. because of its clinical similarity to a salivary gland neoplasm, this condition has been known as kuttner tumor and is classified as a tumorlike lesion. case report: this is the first reported case of bilateral kuttner tumor of the submandibular glands in iran. it was initially diagnosed as a ...

PURPOSE To compare the capabilities of apparent diffusion coefficient (ADC) and normalized ADC using the pancreatic parenchyma as reference organ in the characterization of focal pancreatic lesions. PATIENTS AND METHODS Thirty-six patients with focal pancreatic lesions (malignant, n=18; benign tumors, n=10; focal pancreatitis, n=8) underwent diffusion-weighted MR imaging (DWI) at 1.5-Tesla us...

Background: Shoulder instability with critical bipolar bone loss can be difficult to treat. Anterior glenoid block augmentation and partial humeral head resurfacing is a viable option. Indications: This procedure indicated in patients both anterior (≥20%) an engaging Hill-Sachs lesion. Technique Description: A deltopectoral approach performed, followed by subscapularis tenotomy. The lesion resu...

Exposure of the retina of the rhesus monkey to visible and infrared radiation from CW optical sources like the Sun, xenon lamps, etc. produces small lesions or scotomata which may be classified as thermal or photochemical, depending on the wavelength and duration of exposure. The action spectrum for the production of retinal lesions has been determined for eight monochromatic laser wavelengths ...

Objective(s): In developing countries and worldwide cervical cancer is an important cause of   female mortality. Reports describing the frequency and pattern of abnormal Pap smears in Saudi Arabia, using the revised Bethesda system (RBS) are very few. The current study was conducted to explore the changing pattern of epithelial cell abnormalities (ECA) detected in Pap smears (PS) in females of ...

Objective(s): There are many reports about the role of rostral ventromedial medulla (RVM) in modulating stress-induced analgesia (SIA). In the previous study we demonstrated that temporal inactivation of RVM by lidocaine potentiated stress-induced analgesia. In this study, we investigated the effect of permanent lesion of the RVM on SIA by using formalin test as a model of acute inflammatory pa...
