Tuberculosis continues to be an important cause of morbidity and mortality worldwide. It is the leading cause of infection-related deaths worldwide. Children are amongst the high-risk groups for developing tuberculosis and often pose a challenge to the clinicians in making a definitive diagnosis. The newly released global tuberculosis report from World Health Organization reveals a 50% increase in fatality from tuberculosis in children. Significantly, diagnostic and treatment algorithms of tuberculosis for children differ from those of adults...

Hydroxyurea treatment is recommended for children with sickle cell anemia (SCA) living in high-resource malaria-free regions, but its safety and efficacy in malaria-endemic sub-Saharan Africa, where the greatest sickle cell burden exists, remain unknown. In vitro studies suggest hydroxyurea could increase malaria severity, and hydroxyurea-associated neutropenia could worsen infections. NOHARM was a randomized, double-blinded, placebo-controlled trial conducted in malaria-endemic Uganda, comparing hydroxyurea to placebo at 20 ± 2...

Driveline infections (DLI) remain a major source of morbidity for patients requiring long-term ventricular assist device (VAD) support. We aimed to assess whether VAD driveline exit site (DLES) (abdomen versus chest wall) is associated with DLI. All adult patients who underwent insertion of a Heartware HVAD® or Heartmate II (HMII) between 2009 and 2016 were included. DLI was defined as clinical evidence of DLI accompanied by a positive bacterial swab and need for antibiotics. Competing risks analysis was used to assess the association between patient characteristics and DLI...

The causative organism is not identified in some cases of infected aneurysms, a life-threatening condition. A 68-year-old man presented with chest/back pain and a 1-year history of intermittent fever and fatigue. Computed tomography revealed a thoracic aortic aneurysm. After several negative blood cultures, he was eventually diagnosed with an infected aneurysm caused by Helicobacter cinaedi via gene analysis of an aortic tissue specimen. As H. cinaedi is a low-virulence bacterium, infection with this pathogen should be suspected in cases of aortic aneurysms with unidentified causative organism and a long history of subjective symptoms...

This is a report of an atypical presentation of pyoderma gangrenosum (PG) in a 26-year-old male who had a negative septic screen. The patient had a life-threatening presentation requiring an intensive care unit (ICU) admission for vasopressor support. It was thought that the likely cause of circulatory collapse was an overwhelming cytokine reaction or systemic inflammatory response syndrome (SIRS) secondary to extensive PG lesions rather than septic shock. The patient presented with multiple large ulcers, the largest being 4 cm in diameter on the central chest...

Although the majority of patients with Mycobacterium tuberculosis have pulmonary involvement, some cases have pleural involvement as extra-pulmonary sites of infection. We herein report a case of upper lobe-predominant pulmonary fibrosis that developed in a 47-year-old male with a history of bilateral tuberculous pleurisy. Based on his chest radiological findings, pleuroparenchymal fibroelastosis (PPFE) was most strongly suspected, and a surgical lung biopsy (SLB) was performed to obtain a pathological diagnosis...

Pseudomonas aeruginosa is a common bacterial pathogen in the evolution of bronchiectasis in cystic fibrosis. The appearance of resistant strains of pseudomonas is increasing with the earlier and more liberal use of a range of anti-pseudomonal antibiotics for the treatment of bacterial chest infections. The rationale for treatment and potential benefits of aggressive treatment of resistant strains of Pseudomonas aeruginosa from early in life are discussed.

Background: Inhaled tobramycin is important in the treatment of Pseudomonas aeruginosa ( Pa ) infections in cystic fibrosis (CF). However, despite its use it fails to attenuate the clinical progression of CF lung disease. The bactericidal efficacy of tobramycin is known to be concentration-dependent and hence changing the dosing regimen from a twice-daily (q12h) inhalation to a once-daily (q24h) inhaled double dose could improve treatment outcomes. Objectives: To predict local concentrations of nebulized tobramycin in the airways of patients with CF, delivered with the small airway-targeting Akita ® system or standard PARI-LC ® Plus system, with different inspiratory flow profiles...
