OBJECTIVE Since cytology is the examination utilized for the screening of cervical cancer, it is important to determine its correlation with histologic examination, the gold standard in the diagnosis of cervical disease. STUDY DESIGN A retrospective evaluation was made of 431 patients who presented with colposcopic indication for cervical biopsy between 2003 and 2007. RESULTS In 90.8% (289/...
Abstract Aim Risk stratification of thyroid nodules based on ultrasound scan (USS) features using the TIRADS- or U-scale has been widely adopted. However, management decisions for patients whose work-up provide conflicting information, remains challenging. The aim this study was to assess rate malignancy among those with suspicious cytology after USS-evaluation. Methods Retrospective review cli...
ذرت از تیره poaceaeو زیر تیره punicoideaeاست. گیاهی است که قدرت سازش با شرایط آب و هوایی مختلف دارد و کشت آن در جهان بسرعت رو به افزایش است. گیاهان تیره کندمیان مقدار زیادی دانه های گرده تولید می کند. دانه های گرده گندمیان یکی از مهم ترین آلرژن ها د رجهان در طی فصول بهار و تابستان محسوب می شوند. این گرده ها درااری 20 ترکیتب فعال آنتی ژنتیک می باشند. هدف این پژوهش بررسی مراحل تکوینی اقدام زایشی...
Background & Aim: Fine needle aspiration biopsy(FNAB) is a well recognized diagnostic method in various organs. Since it is a non-invasive, quick, easy and cost - effective procedure, it is considered suitable for clinical evaluation of various lesions. The goal of this analytical cross-sectional study is to evaluate the value of cytology of cutaneous and subcutaneous nodules as a diagnosti...

BACKGROUND In qualitative diagnosis of bile duct stenosis, single diagnostic measure is difficult to make a correct diagnosis, to combine several diagnostic techniques may be helpful to make an accurate diagnosis. The aim of this study was to evaluate the value of intraductal ultrasonography (IDUS), endoscopic brush cytology and K-ras, P53 gene mutation in the early diagnosis of malignant bilia...
INTRODUCTION We evaluated the UroVysion (Abbott Molecular, IL, USA) fluorescence in situ hybridization (FISH) assay for the diagnosis of urothelial cancer in patients diagnosed with or suspected to have bladder, upper tract urothelial carcinoma (UTUC), and combined upper and lower tract urothelial carcinoma (BC). MATERIALS AND METHODS A single institution retrospective analysis comparing sens...
Extrahepatic biliary stenosis can be caused by benign and malignant disorders. In most cases, a tissue diagnosis is needed for optimal management of patients, but the sensitivity of biliary cytology for the diagnosis of a malignancy is relatively low. The additional diagnostic value of K-ras mutational analysis of endobiliary brush cytology was assessed. Endobiliary brush cytology specimens obt...
BACKGROUND Human papillomavirus (HPV)-based screening needs triage. In most randomized controlled trials (RCTs) on HPV testing with cytological triage, cytology interpretation has been blind to HPV status. METHODS Women age 25 to 60 years enrolled in the New Technology in Cervical Cancer (NTCC) RCT comparing HPV testing with cytology were referred to colposcopy if HPV positive and, if no cerv...
Abstract Background To evaluate the clinical effectiveness of a novel CellDetect staining technique, compared with fluorescent in situ hybridization (FISH), and urine cytology, diagnosis urothelial carcinoma (UC). Methods A total 264 patients suspicious UC were enrolled this study. All tissue specimens collected by biopsy or surgery. Urine specimen was obtained for examinations prior to surgica...
