conclusion hsg is considered to have a high sensitivity and specificity. hsg and laparoscopy are not alternative, but are the complementary methods in the examination of no tubal patency. results the sensitivity and specificity of hsg on bilateral tubal patency or no bilateral tubal patency were 92.1% and 85.7% respectively. the positive and negative predictive values were 97.2% and 66.7%, and ...
background and aims: iron deficiency anemia (ida) and beta thalassemia minor (btm) are the most common hypochromic microcytic anemias, and it is regarded important to differentiate between them. several formulae can be taken into consideration based on red blood cell (rbc) parameters in order to distinguish between these two disorders. hence, the present study intended to evaluate the sensitivi...
Background: The purpose of our study was to assess the potential of color Doppler (CD) and Power Doppler Imaging (PDI) to differentiate benign from malignant solid breast masses. Materials and Methods: Seventy-one biopsy proven solid breast masses were evaluated with CD and PDI using 7.5 MHZ Transducer. Vascularity, Resistive Index (RI) and patterns of vascular distribution of masses were assig...
background: positron emission tomography (pet) scan is a non-invasive, complicated and expensive medical imaging technology used for diagnosis and treatment of various diseases including cancers. this study aimed to evaluate the safety and effectiveness of this technology in iran. methods: the major medical electronic databases including cochrane library, google scholar, medline and iranmedex w...
Background and purpose: Airway assessment is very important in anesthesia. The aim of this study was to determine the diagnostic value of Mallampati test indicators in supine and sitting positions with and without phonation in anesthesia candidate patients. Materials and methods: This cross-sectional descriptive study (diagnostic approach) was done in 200 adult patients ≥16 years, undergoing s...
Helicobacter pylori (H.pylori) is the most prominent causative agent of gastroduodenal diseases all over the world. Other manifestations such as urticaria and coronary heart diseases, also are suspected to be induced by H.pylori. Non invasive methods are preferred for diagnosis and ELISA, because of its reliability, speed, sensitivity and specificity is widely preferred as diagnostic tool. Prev...
background: according to recent studies comparing magnetic resonance enterography (mre) with ileocolonoscopy for assessing inflammation of small bowel and colonic segments in adults with active crohn’s disease (cd), we aimed to compare the accuracy of these two diagnostic methods in iranian population. method: during 2013-2014 a follow-up study was done on 30 patients with active cd ina gastroe...
ABSTRACT Attention to high prevalence of inflammatory disease of upper gastrointestinal system and determination of Helicobacter pylori, “a great importance etiology of gastric disorders”, this study was performed for rapid diagnostic evaluation of Helicobacter pylori. This observational & cross-sectional study was performed in 100 cases who suffered from upper gastrointestinal symptoms. By an ...
Introduction: Patients with Cystic Fibrosis have increased risk of malnutrition. Early detection of nutritional deterioration enables prompt intervention and correction. The aims of this project were to: - Define the nutritional status of CF patients in Iran and New Zealand - Compare and contrast the MacDonald Nutritional Screening tool with the Australasian guidelines for Nutrition in Cyst...
background: accumulation of pleural and peritoneal fluid is seen in some diseases. in order to diagnose the disease and start the treatment, one of the most important actions will be to differentiate between exudates and transudates. the objective of this study was to determine the diagnostic value of measuring the specific gravity of the fluid through refractometer and strip in differentiation...
