ABSTRACT
CONTEXT: Mycobacterium tuberculosis (MTB) infection is rarely seen in cystic fibrosis (CF) patients. CASE REPORT: We report a 24-year-old CF patient with fever, cough, hemoptysis, and weight loss of 1week duration prior to admission. Past sputum cultures grew methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa. The patient was treated with broad spectrum antibiotics based on previous culture data, but failed to improve. Chest radiograph and computed tomography (CT) chest revealed chronic collapse of the anterior subsegment of right upper lobe and multiple bilateral cavitary lesions which were worse compared to prior films. MTB was suspected and was confirmed by positive acid-fast bacilli (AFB) smears and cultures. After receiving first-line antituberculous drugs, the patient's condition markedly improved. CONCLUSION: MTB is an infrequent finding, but considered a potential pathogen in CF patients, and may lead to serious pulmonary complications if there is a delay in diagnosis and treatment.
ABSTRACT
Cystic Fibrosis (CF) is a multisystem disease predominantly affecting the airways and predisposing patients to recurrent infections with various multidrug resistant organisms. Mycobacterium tuberculosis (MTB) infection is rarely seen, but considered a potential pathogen in CF patients. We report a 26 year old pregnant CF patient on Ivacaftor who was admitted with symptoms suggestive of tuberculosis. Three years prior to the current admission, she had completed four drug anti- MTB therapy for pulmonary tuberculosis and was considered cured as her sputum cultures after six months of treatment were negative. Genotype analysis revealed the current MTB strain to be different from the strain causing the previous infection. After receiving first line anti-tuberculous regimen for nine months, the patient's condition markedly improved culminating in an uneventful pregnancy and delivery. To our knowledge, this is the only reported case of reinfection tuberculosis in a CF patient.

Ultrasound-guided transbronchial needle aspiration using the bronchoscope with a dedicated curvilinear probe has emerged as a primary tool for the investigation of mediastinal pathology. Recently, the utility of this scope has been expanded to include access via the esophagus. In this case series, we describe a role for esophageal ultrasound using the endobronchial ultrasound bronchoscope in the diagnostic evaluation of critically ill/intubated patients with mediastinal disease. Esophageal access with the ultrasound bronchoscope allows the pulmonologist to diagnose mediastinal disease in the intubated patient with minimal risk.

Aspergillus brain abscess is a rare clinical entity, which remains a challenge to diagnose and treat. Most fungi are low virulence organisms, often living as commensals. They however, pose a considerable challenge in an immune-compromised host. Systemic steroids are commonly used in treatment of various inflammatory conditions. Despite their relatively safe profile, one peril of such treatment is immune suppression. It is prudent that physicians remain aware of the risk of various opportunistic infections in such patients. We present a case of fatal intra-cranial aspergillosis in an immuno-compromised patient on systemic steroids.
