A 57-year-old male was found to have papillary transitional cell carcinoma of the urinary bladder and underwent a tranurethral resection of the tumor. He suffered from multiple asymptomatic red papules on glans penis after 9 th intravesical therapy with Bacillus Calmette-Guerin (BCG ). His left inguinal lymph node was enlarged and tender. The skin lesions were found to be due to suppurative gra...

AIMS Despite its long history, the acid fast smear remains unstandardised. Technical variations in both the preparation of clinical material and subsequent staining mean that smear sensitivity relative to culture may vary from 50% to over 80%. This study assessed the sensitivity of acid fast microscopy at each of five stages of sample preparation and by both commonly used staining methods. ME...

A polymerase chain reaction (PCR) protocol for detecting IS6110 repetitive insertion sequence of Mycobacterium tuberculosis (MTB) was tested on archival Papanicolaou (Pap)-stained fine needle aspirated (FNA) smears from 24 patients with cervical tuberculous lymphadenopathy and 30 negative controls. The protocol involved protease digestion or phenolchloroform extraction, and simple or nested PCR...

Lepromatous leprosy is a sys temic disorder. In many cases there is extensive involvemen,t not only of the reticuloendothelial system, but also of other organs. Intimal cells of blood vessels may be almost bursting with leprosy bacilli. Liver changes in lepromatous leprosy are well known. They consist chiefl y of foam-cell granulomas, with or without acid-fas t bacilli, in the portal ti ssues a...

OBJECTIVE Auramine-phenol stain was compared with Kinyoun's acid-fast stain to detect coccidia parasites in fecal samples from immunocompromised patients. The comparison was based on the number of detected cases, sensitivity, specificity, time required for the procedure, ease of use, interpretation, and cost. METHODS A total of 112 fecal specimens were examined by conventional methods: Direct...

background and objective: tuberculosis is still a major health problem, involving about 1/3 of the world´s population. diagnosis is difficult when we only use ziehl-neelson staining. many cases may be missed. a more rapid and sensitive diagnostic method is necessary. pcr may be helpful. the aim of this study was to compare pcr, zieh-neelsen staining and histopathologic findings in diagnosis of ...

UNLABELLED The resurgence of Mycobacterium tuberculosis in association with HIV infection has focussed much attention in the rapid diagnosis of high risk cases. Infection with HIV is known to alter the presentation of pulmonary tuberculosis. The present study was under taken to compare the efficacy of fluorochrome stain (Fl) with conventional Ziehl Neelsen (ZN) stain in the diagnosis of pulmona...
