Purpose: The purpose of this study was to determine differences in pretreatment and posttreatment radiographic findings in pulmonary tuberculosis (PTB) patients with and without human immunodeficiency virus (HIV) infection.
Materials And Methods: All patients were reviewed in terms of pre- and posttreatment radiographic findings comparing non-HIV-related versus HIV-related PTB.
Results: Among 177 PTB patients, 38 (22%) were HIV seropositive and 139 (78%) were HIV-seronegative. The most common radiographic finding in non-HIV-related TB was reticular infiltration (66.2%), whereas the miliary pattern was the most common radiographic finding in HIV-related TB (34.2%). Radiographic findings in HIV related TB significantly presented with higher prevalence of the miliary pattern (P < 0.0001) and lower prevalence of reticular infiltration (P < 0.0001), cavitation (P = 0.003), and mass-like lesions (P = 0.039) compared to non-HIV-related TB. During the posttreatment period, normal chest radiographs were significantly present in the patients who had HIV-seropositivity, the miliary pattern, and sputum negative for acid-fast bacilli during the pretreatment period (P < 0.05).
Conclusion: Pretreatment radiographic features of HIV-related TB had a significantly higher prevalence of the miliary pattern and lower prevalence of reticular infiltration, cavitation, and mass-like lesions. HIV-related TB and the miliary pattern seen by pretreatment radiography were significantly associated with normal chest radiographs during the posttreatment period.

Introduction: BCG therapy is the standard treatment for bladder tumors that do not infiltrate smooth muscle. Fluoroquinolones for antibiotic prophylaxis are recommended to lessen the risk of BCG infection (BCGitis) with respiratory involvement.
Case Report: This study describes five cases of BCGitis in males, with a median age of 71years [range: 66-77years] having undergone ofloxacin prophylaxis during their BCG therapy for a non-invasive bladder tumor (grade pT1a).

Introduction: Candida albicans infection shows a wide range of patterns on chest computed tomography, including ground glass opacities and consolidation, with the miliary pattern being the least frequent. The miliary pattern is not exclusive to tuberculosis. Fungal lung infections are rare and potentially fatal.

Background: Histoplasma is a fungal pathogen found in many parts of the world. In North America, its distribution is traditionally thought to be endemic to the Ohio and Mississippi River valleys. Development of histoplasmosis after Histoplasma exposure is related to degree of inoculum exposure and susceptibility, for example, immunocompromised status.

Article Synopsis
- * The report details a case of a 39-year-old woman who suffered from a seizure; her normal chest X-ray delayed the detection of MTB, ultimately leading to severe health consequences.
- * It underscores the limitations of traditional chest X-rays in diagnosing MTB, recommending more advanced imaging techniques like chest CT or MRI, and stresses the importance of timely treatment, especially in developing countries affected by conflict and poverty.

Objectives: Although a "multisite" definition of disseminated tuberculosis (DTB) exists, there is limited evidence to support its use. Herein, we sought to generate that evidence.
Methods: We evaluated treatment outcomes and reporting requirements against two distinct definitions of DTB in a 15-year population-based cohort of consecutively diagnosed patients with tuberculosis (TB) in Canada.
