In Uruguay (population 3,323,906; notified tuberculosis incidence 18.4/100,000), virtually all 30,000 samples yearly collected for mycobacterial culture countrywide are processed in a central laboratory. An average of 110 samples are routinely shipped daily and maintained 48-96 hours at room temperature until cultured on Löwenstein-Jensen slants using the standard NALC-NaOH decontamination proc...

Buschke-Löwenstein tumor (BLT), known as giant condyloma acuminatum (GCA), is a very rare disease that typically appears as a penile lesion but can although appear in the anogenital region, bladder, vulva, scrotum and sacrococcygeal area as well. Despite of its histologically benign signs, a high recurrence rate, invasiveness and destructive growth characterizes this rare disease as clinically ...

UNLABELLED The current study was aimed to evaluate the performance of direct 2,3,5-triphenyl tetrazolium chloride assay and direct microscopic observation drug susceptibility assay with indirect Löwenstein-Jensen proportion method directly on Ziehl-Neelsen smear positive sputum specimens. METHODS Direct acid fast bacilli smear positive sputum specimens (n=264) were subjected to isoniazid and ...

BACKGROUND Resistance to commonly used antituberculosis drugs is emerging worldwide. Conventional drug-susceptibility testing (DST) methods are slow and demanding. Alternative, rapid DST methods would permit the early detection of drug resistance and, in turn, arrest tuberculosis transmission. METHODS A cost-effectiveness analysis of 5 DST methods was performed in the context of a clinical tr...

We investigated the effect of aluminum distribution in adsorption properties carbon dioxide MFI, MOR, and ITW zeolites. Because its lack experimental evidence theoretical validation, Löwenstein’s rule was not generally imposed, special attention paid to Al–O–Al linkages. To this end, we first generalized an existing transferable force field for CO2 non-Löwenstein By means molecular simulations ...

BACKGROUND Molecular resistance testing fails to explain all fluoroquinolone resistance, with a continued need for a suitable rapid phenotypic drug susceptibility testing method. OBJECTIVE To evaluate the optimal method for phenotypic fluoroquinolone susceptibility testing. METHODS Using Löwenstein-Jensen medium, Middlebrook 7H11 agar, BACTEC-MGIT 960 and the resazurin microtitre plate assa...

Buschke-Löwenstein tumor is a rare manifestation of a sexually transmitted human papilloma virus infection that affects the anogenital area. Wide local excision of the lesion is the mainstay of treatment. Malignancy though must be excluded.

Introduction: Early recurrence of hepatocellular carcinoma (HCC) is a major risk factor affecting survival even after hepatectomy. Many clinical, biochemical parameters and pathological grading like fibrosis 1 index have been used for risk stratifying HCC. However not many studies have combined all of them. It is therefore important to risk stratify HCC especially with newer PE...

INTRODUCTION Verrucous carcinoma of the external genitalia and perianal region is a rare variant of well-differentiated squamous cell carcinoma. It has been reported to have limited metastatic potential. CASE PRESENTATION We report the case of a 54 year-old Moroccan man who presented with locally advanced giant condyloma acuminatum (Buschke-Löwenstein tumor) after prolonged intervals of negle...
