Comparison of fine needle aspiration and direct skin smear in the diagnosis of acute cutaneous leishmaniasis: polymerase chain reaction as a reference method

Background: Accurate diagnosis of cutaneous leishmaniasis wouldavoid unnecessary treatment and scar formation. Direct smear isthe most common method for the diagnosis of this disease but itsnegative result could not rule out the infection; so, the need formore sensitive methods is obvious. We conducted this study tocompare the efficiency of direct skin smear with smears preparedby fine needle a...

EVALUATION OF DIRECT MICROSCOPY, CULTURE, AND POLYMERASE CHAIN REACTION FOR THE DIAGNOSIS OF TUBERCULOUS MENINGITIS

In view of the importance of early diagnosis of tuberculous meningitis (TBM), the efficiency of the polymerase chain reaction (PCR), one of the most reliable and sensitive DNA-based assays, was compared with conventional methods (acid-fast microscopy and culture) for the detection of M. tuberculosis in cerebrospinal fluid (CSF) specimens from patients suspected of TBM. Of the 29 CSF specim...

Fetal RHD Genotyping Using Real-Time Polymerase Chain Reaction Analysis of Cell-Free Fetal DNA in Pregnancy of RhD Negative Women in South of Iran

Objective Maternal-fetal RhD antigen incompatibility causes approximately 50% of clinically significant alloimmunization cases. The routine use of prophylactic anti-D immunoglobulin has dramatically reduced hemolytic disease of the fetus and newborn. Recently, fetal RHD genotyping in RhD negative pregnant women has been suggested for appropriate use of anti-D immunoglobulin antenatal prophylaxi...

Detection of Plasmodium falciparum Directly from Blood Samples Using the Polymerase Chain Reaction

Polymerase Chain Reaction Study of Anogenital Condylomas for High Risk HPV Types

Background: Anogenital wart is a common sexually transmitted disease affecting both genders. The aim of this study was to evaluate human papilloma virus types of anogenital warts with Polymerase Chain Reaction (PCR). Method: 65 formalin fixed paraffin embedded (FFPE) tissue blocks of the anogenital warts obtained from the pathology lab of Loghman Hakim hospital were included in this study. Resu...

Development of New Modified Simple Polymerase Chain Reaction and Real-time Polymerase Chain Reaction for the Identification of Iranian Brucella abortus Strains

Brucellosis is primarily a worldwide zoonotic disease caused by Brucella species. The genus Brucella contains highly infectious species that are classified as biological threat agents. In this regard, the identification of Brucella can be a time-consuming and labor-intensive process posing a real risk of laboratory-acquired infection to the laboratory staff. This stud...
