In addition to its well-known homoeostatic actions in the cardiovascular system, ET-1 has been shown to constitute a potent growth regulatory peptide in various tissues. We have studied the expression of ET-1 and its receptors (ETAr and ET-Br) in human meningiomas (n = 35) as well as their involvement in cellular growth. By PCR of reversetranscribed RNA we detected ET-1 mRNA in 91% (32 of 35), ...

A discrete MIBI avid lung lesion was found in cinematic views of myocardial perfusion imaging (MPI) of a 59 year-old woman. Interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. MPI was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  She had no...

TC is a rare disorder, characterized by calcified tumors and dysfunction of large joints. To date there have been no reports of calcification involving the airway. CD is a 43 year old male with a long history of TC who developed dysphagia prompting otolaryngic evaluation. He was fo...

background: linear endoscopic ultrasonography (eus) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. the aim of this study was to describe the role of eus-fna in the evaluation of pancreatic and submucosal lesions. materials and methods: over a 1-year period, in a prospective descriptive study, patients referred to naft hospital, underwent linear eus. ...

Introduction: Rhinophyma is an uncommon subtype of rosacea, the clinical diagnosis of which is straightforward. However, localized, especially well-circumscribed,  rhinophyma is a very rare condition, which requires a paraclinical assessment to be accurately diagnosed.   Case Report: We report a 48-year-old male patient who presented with a well-circumscribed and dark re...

"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...

Chronic shoulder pain can be caused by muscle, bone and joint inflammatory and tumoral lesions; however, chronic shoulder pain secondary to benign vascular tumor called glomus tumor is an extremely rare occurrence. To the best of our knowledge less than 15 cases of chronic shoulder pain have been reported secondary to glomus tumor. Herein we report our experience with a young lady who presented...

Galactoceles are the most common benign breast lesions during breastfeeding period that can mimic carcinomas. We report a galactocele with malignant appearance on ultrasound in the accessory breast. The patient was a 32-year-old lactating woman presented to our hospital for considerable swelling in the left axilla. Ultrasound examination revealed a hypoechoic mass with heterogeneous echogenicit...
