Good’s syndrome is a relatively rare immunodeficiency condition that presents in the fourth or fifth decade of life and is defined by hypogammaglobulinemia in the setting of a thymoma. The humoral defect may be severe enough to cause an absence in B cells, with a consequent recurrence of sinopulmonary disease, chronic non-infectious diarrhea and opportunistic infections. The prognosis in patien...
Intra-cavitary cardiac tumours are rare and a high index of suspicion is required on the part of the physician to make the clinical diagnosis. With the advent of two dimensional real time echocardiography this diagnosis can be easily and rapidly confirmed. Over the past two decades M-mode echocardiography has been widely used for the diagnosis of left atrial myxomas. Though it has been shown to...
Background Pulmonary sporotrichosis is a rare disease caused by a dimorphic fungus, Sporothrix schenckii. It is rarely found in association with malignancy. We present a case of pulmonary sporotrichosis recurrence after chemotherapy. Case Presentation A 44-year-old man, treated for pulmonary sporotrichosis in the past, presented with dysphagia and was found to have squamous cell carcinoma of ...
Mucinous adenocarcinoma represents a rare subtype of adenocarcinoma of the lung, which is frequently invasive and has a poorer prognosis. Of its wide range of imaging appearances, air-space consolidation is the most frequent pattern while cavitary form has only rarely been reported. Despite imaging advancements, the differentiation of benign and malignant cavitary lung lesions sometimes remains...
The rabbit model of tuberculosis is attractive because of its pathophysiologic resemblance to the disease in humans. Rabbits are naturally resistant to infection but may manifest cavitary lung lesions. We describe here a novel approach that utilizes presensitization and bronchoscopic inoculation to reliably produce cavities in the rabbit model. With a fixed inoculum of bacilli, we were able to ...
A critical element of tuberculosis control is early and sensitive diagnosis of infection and disease. Our laboratories recently showed that different stages of disease were distinguishable via two-dimensional Western blot analyses of Mycobacterium tuberculosis culture filtrate proteins. However, this methodology is not suitable for high throughput testing. Advances in protein microarray technol...
Postprimary tuberculosis occurs in immunocompetent people infected with Mycobacterium tuberculosis. It is restricted to the lung and accounts for 80% of cases and nearly 100% of transmission. Little is known about the immunopathology of postprimary tuberculosis due to limited availability of specimens. Tissues from 30 autopsy cases of pulmonary tuberculosis were located. Sections of characteris...
Hot tub lung (HTL) is a granulomatous lung disease thought to occur as a result of a hypersensitivity response to non-tuberculous mycobacteria (NTM). Typical radiographic findings are diffuse micronodular and/or ground glass opacities. We report an interesting case of HTL that presented with unique radiographic features, making its diagnosis a predicament. A 56-year-old immunocompetent female w...
It should have been a wake-up call. Thirty years ago, TOMLINSON and SAHN [1] found that seven out of 12 (58%) patients with aspergillosis complicating sarcoidosis died over a 2 year period. Three years earlier, WOLLSCHLAGER and KHAN [2] had found evidence of aspergillosis in 12% of 100 consecutive sarcoidosis referrals, and aspergillomas were found in 53% of the 19 patients with fibrocystic asp...
