BACKGROUND Many adults with pulmonary tuberculosis are unable to expectorate. Gastric washing, sputum induction using nebulized hypertonic saline, and bronchoscopy with bronchoalveolar lavage have all been used to obtain specimens for diagnosis, but to our knowledge, the timing and volume of induced sputum have not been well studied, and these 3 methods have not been compared. METHODS The stu...

BACKGROUND Modern molecular-based approaches for the detection of Mycobacterium tuberculosis in sputum samples promise quicker and more accurate detection of cases. However, processing sputum samples at central diagnostic facilities provides a diagnostic approach, but requires a safe and efficient system that is not affected by transport delays and ambient temperature to be feasible. We evaluat...

conclusions with regard to the ease of urine sample preparation and the 100% specificity the pcr method, performing urine pcr could be used as a diagnostic aid in ptb cases obtaining sputum samples is problematic. results results of the current study indicated that 48 (62.3%) patients out of 77 had a positive sputum culture. urine cultures and acid-fast smears were negative. urine pcr-tb was po...

background: one-third of the world’s population is currently infected by tubercle bacillus. this study was performed to evaluate epidemiological and clinical aspects of confirmed cases of tuberculosis infections in a seven-year time period, between years of 2002 to 2008, in the city of hamadan, west of iran. materials and methods: in this descriptive retrospective study, medical records of 375 ...

The Gen-Probe Amplified Mycobacterium Tuberculosis Direct (MTD) test has been approved for use in the United States for the rapid diagnosis of pulmonary tuberculosis in patients with acid-fast smear-positive sputum samples since 1996. Four patients infected with human immunodeficiency virus and one chronic pulmonary-disease patient seen in our institutions with abnormal chest radiographs and fl...

BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) is an important global health problem. Furthermore, the time to identify a positive sputum culture is an important risk factor for the spread of tuberculosis, and several factors can predict a prolonged time to culture conversion. Moreover, the relationship between poor nutritional status and infectious disease is clearly established. Therefo...

BACKGROUND Bacteriological confirmation of pulmonary tuberculosis is difficult in infants and young children. In adults and older children, sputum induction has been successfully used; this technique has not been tested in younger children. AIMS To investigate whether sputum induction can be successfully performed in infants and young children and to determine the utility of induced sputum co...

The Pulmonary Tuberculosis has been known to mankind cause increased morbidity and mortality especially in elderly. There is delay diagnosis of pulmonary tuberculosis which led mortality. Hence, this study looks into the pattern presentations radiological features that these patients demonstrate, may help early effective management. A cross-sectional, descriptive was conducted on seventy above ...

objective: trichomonas species usually reside in the mouth and occasionally in the respiratory tract. these species can be found in the lungs of humans. although the pathogenicity of the parasite in the respiratory system has not been proven, it is more prevalent in people who lack good oral health or suffer from asthma or chronic pulmonary diseases. in the present descriptive study, we have id...
