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: sonoelastography (se) is introduced as a complementary technique for ultrasoungraohy (us) to evaluate breast lesions. this method is based on tissue strain in response to compression and decompression. the current study was designed to investigate the diagnostic performance of se for differentiating between benign and malignant breast lesions methods: a total of 35 women with 45 bre...

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...

objective: anti-cyclic citrullinated peptide (anti-ccp) antibodies are highly specific markers for rheumatoid arthritis (ra) and useful for predicting rheumatoid arthritis (ra) development and progression. we assessed the diagnostic value of anti-ccp antibodies in our patients with ra. materials and methods: anti-ccp antibodies and rheumatoid factor (rf) titers were determined in 247 serum sam...

background paranasal sinus ct has high sensitivity and specificity for sinusitis. however, this modality is costly and involves greater radiation exposure than plain radiographs. objectives we tried to compare 10-cut limited ct scan and standard ct scan in the diagnosis of sinusitis. materials and methods we conducted a cross sectional case series from august to december 2010 on 150 patients wi...

Background: Colorectal cancer (CRC) is the third most common cancer worldwide. microsatellite instability (MSI) is a molecular marker of a deficient mismatch repair system and happens in almost 15% of CRCs. Because of a wide frequency of MSI+ CRC in Iran compared to other parts of the world, the importance of screening for this type of cancer is highlighted. Methods: The most common MSI detecti...

Background: Value of Corticosteroid Randomisation after Significant Head Injury (CRASH) prognostic model has not been assessed in children with traumatic brain injury (TBI). This study is designed to examine the value of CRASH model in prediction of 14-day mortality and 6-month unfavourable outcome of pediatric TBI. Materials and Methods: </stron...

Ejection fraction is the most important indicator of heart failure. Angiography , is a standard method to demonstrate ejection fraction but it is invasive. Therefore determination of sensitivity and specificity of echocardiography versus angiography is a good guidance for physicians. A total number of 50 patients were enrolled in a prospective study. Two dimension and M-Mode echocardiography...
