تومور buschke-lowenstein tumor (blt) یا تومور گل کلمی شکل یا کوندیلوم آکومیناتوم بزرگ giant condyloma acuminatum (gca) با رشد آهسته و تهاجم موضعی است که اندازه بزرگی دارد و معمولاً در ناحیه پرینه ایجاد می شود. blt توسط ویروس پاپیلومای انسانی، معمولاً توسط ژنوتیپ 6 یا 11 ایجاد می شود. blt معمولاً در زمینه condyloma acuminatum ایجاد می شود و در هر سنی بعد از دوران بلوغ می تواند بروز کند. ولی معمولاً ...
BACKGROUND There is an urgent need for low-cost methods for rapid, accurate detection of Mycobacterium tuberculosis in clinical specimens. The microscopic-observation drug-susceptibility (MODS) assay is a relatively low-cost and simple liquid culture method that has been proposed for use in resource-limited environments. METHODS This prospective study evaluated the performance of the MODS ass...
There is an urgent need to improve the methods used for the bacteriological diagnosis of childhood mycobacterial disease. This study compared the mycobacterial yields and the times to detection (in days) of mycobacteria in pediatric clinical specimens by using Mycobacterial Growth Indicator Tubes (MGITs) and solid Löwenstein-Jensen (LJ) slants with and without a nutrient broth supplement. A tot...
BACKGROUND Surveillance and effective management of drug resistance is important to sustaining tuberculosis (TB) control efforts. We aimed to determine resistance rates to first line anti tuberculosis drugs and to describe factors associated with the resistance to any of the first line anti tuberculosis drugs in Dar es Salaam Tanzania. MATERIALS Newly diagnosed, TB patients with neither histo...
BACKGROUND & OBJECTIVES In human immunodeficiency virus (HIV) infected persons with pulmonary tuberculosis (TB), sputum may not always show acid fast bacilli (AFB). Moreover, in most cases of suspected extrapulmonary TB (irrespective of HIV status) mycobacteria-containing material is not readily available for investigation. This study evaluated whether blood culture for Mycobacterium tuberculos...
The laboratory diagnosis of tuberculosis usually relies on culture-based isolation of the causative Mycobacterium tuberculosis bacteria. We developed and evaluated the performance of MOD9, a new blood-free derivative of the MOD4 solid medium on which we previously reported for the isolation and culture of mycobacteria. First, inoculation of Lowenstein-Jensen medium with 21 M. tuberculosis isola...
In this and the previous volume on lipids, Vol. XXXIV, Lowenstein has assembled two of the stronger recent volumes in this series. The first volume dealt with the enzymes of lipid synthesis and degradation, general analytical methods, and the preparation of substrates. This new volume is divided into the same sections, although the bulk of the book is concerned with enzymes. I think this is the...
