Methodology In Madinah, a case-control was conducted between October 2022 March 2023. Two oral cytologic smear samples were collected from each 500 volunteers; 250 consumers cigarettes non-smok...

Macroscopic purulence, leukocyte counts, and bacterial morphotypes in Gram-stained smears were investigated in 335 sinus secretions (240 aspirates and 95 injection aspirates) obtained by puncture in 234 young patients with acute maxillary sinusitis. Over 90% of the 147 aspirates macroscopically classified as purulent also contained high numbers of leukocytes (greater than 20 per oil immersion f...

Leukemia, the malignancy of blood-forming tissues, becomes fatal if not detected in early stages. It is through a blood smear test that involves morphological analysis stained slide. The manual microscopic examination slides tedious, time-consuming, error-prone, and subject to inter-observer intra-observer bias. Several computerized methods automate this task have been developed alleviate these...

BACKGROUND AND OBJECTIVES Diagnosis of tuberculosis (TB) is largely based on microscopy and culture examination which are either less sensitive, or time consuming. In the present study a PCR (polymerase chain reaction) test based on DNA sequence coding for a 38-kilodalton protein antigen b (Pab) ,specific for Mycobacterium tuberculosis was compared with Ziehl-Neelsen (ZN) stained AFB (acid fast...

As a result of disposal problems related to the use of mercury compounds, many laboratories have considered switching from mercuric chloride-based Schaudinn's and polyvinyl alcohol (PVA) stool preservatives to other non-mercury-based preservatives. The primary use for PVA-preserved specimens is the permanent stained smear, the most important technique in the routine ova and parasite examination...
