The Comparison of Direct Microscopic Examination and Culture Results in Diagnosis of Cutaneous Leishmaniasis

Abstract Background and Objectives: one of the endemic foci for Cutaneous Leishmaniasis in Iran is Mashhad in which limited outbreak have recently been reported. The commonly used method for diagnosis is the clinical features confirmed by direct microspic examination and culture or biopsy. We compared these two tests to determine the level of their sensitivity, specificity and positive predicti...

Misinformation from sputum cultures without microscopic examination.

Only 13 of 38 hospital laboratories surveyed include a Gram stain routinely in microbiological sputum examination. In a prospective three-hospital study, 60% of over 1,200 "sputum" specimens consisted predominantly of saliva, as judged by cell composition. Compared with the results of cultures in which microorganisms presumptively identified on sputum smears were specifically sought ("directed ...

quality control of sputum smears examination by re-reading in a tuberculosis screening

background: sputum smear examination is the basis of diagnosis of tuberculosis and quality control for the correct diagno­sis of tuberculosis is necessary. this study was a method survey and performed with 930 smears with the aim to compare the confidence rate of sputum smear examination reported by one laboratory technician with the findings reported by two techni­cians in a tuberculosis scree...

Some Aspects of Sputum Examination in Tuberculosis Case-finding

For the purpose, overnight collected sputum specimens are considered superior to spot specimens (Andrews & Radhakrishna, 1959) though not always (Rao et al, 1966).
