background: pneumocystis carinii is one of opportunistic organisms especially in immuno-compromised patients. for years, diagnosis of pneumocystis pneumonia (pcp) has relied on microscopic visualization of organism in specimens obtained from the lung either by bronchoalveolar lavage (bal) or by induction of sputum, but failed to provide efficient diagnosis. the aim of this study was to compare ...

Scabies is a common, highly contagious skin parasitosis caused by Sarcoptes scabiei var. hominis. Early identification and prompt treatment of infested subjects is essential, as missed diagnosis may result in outbreaks, considerable morbidity, and significantly increased economic burden. The standard diagnostic technique consists of mites' identification by microscopic examination of scales obt...

BACKGROUND We designed a simple and integrated diagnostic algorithm for acute pulmonary embolism (PE). Diagnosis was based on clinical probability assessment, plasma D-dimer testing, then sequential testing to include lower limb venous compression ultrasonography, ventilation perfusion lung scan, and chest multidetector CT (MDCT) imaging. METHODS We included 321 consecutive patients presentin...

Hepatocellular carcinoma (HCC) is the 6th most common cancer in the world and the third most common malignant tumor following stomach and lung cancers in Korea. Approximately 90% of HCCs are associated with a known underlying risk factor. The most frequent risk factors include chronic viral hepatitis (hepatitis B virus, hepatitis C virus) and alcohol intake. Cirrhosis is an important risk facto...

hepatobiliary scintigraphy is a sensitive method for intra & extera hepatic bile leak diagnosis. bile lead may be seen after hepatobiliary surgery, trauma, inflammatory disease or malignant neoplasms. although sonography and ct scanning are useful for diagnosis of peritoneal or perihepatic fluid, they cannot prove bile ascites. hepatobiliary scintigraphy with tc-99m-ida agents is a physiolo...

We evaluated the system accuracy of noninvasive prenatal diagnosis for abnormal chromosome genetic diseases using cell-free fetal DNA in maternal plasma. Previous studies were searched in the MEDLINE database using the following keywords: "prenatal" and "aneuploidy" and "noninvasive or non-invasive" and "maternal". Identified studies were filtered using a QUADAS instrument. Four studies were id...

For decades, noninvasive analysis of the fetal genotype has been the holy grail of the field of prenatal diagnosis. Noninvasive prenatal diagnosis (NIPD) would use a sample source other than amniocentesis or chorionic villus sampling. The focus has been primarily on the use of maternal blood samples, with less attention given to the possibility of recovering fetal cells from maternal cervical s...

background in the diagnosis of malignant lymph nodes (lns) and staging of lung cancer, sampling of mediastinal and hilar lns is essential. mediastinoscopy is known as the gold standard. convex probe (cp) endobronchial ultrasound (ebus)-guided transbronchial needle aspiration (tbna) is a noninvasive and highly sensitive diagnostic method in mediastinal and hilar ln sampling. objectives evaluatin...
