BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is guided-bronchoscopy to pulmonary nodules (PN) which relies on a pre-procedural chest CT to create a 3-dimensional (3-D) virtual airway map. The CT is traditionally done at a full inspiratory breath hold (INSP) but the procedure is performed while the patient tidal breaths, where lung volumes are closer to functional residual capacity. Movement of a PN from INSP to expiration (EXP) has been shown to average 17.6 mm. Therefore, the hypothesis of this study is that pre-procedural virtual maps built off a CT closer to physiological lung volumes during bronchoscopy may better represent the actual 3-D location of a PN...

BACKGROUND: Epithelioid haemangioendothelioma (EHE) is a rare low-grade vascular neoplasm that can arise in the lung, liver, soft tissues or, less commonly, bone. Due to its low prevalence of less than one in a million and its non-specific clinical features, EHE is often misdiagnosed and managed inappropriately. Here we discuss the case of a 58 year-old gentleman with mediastinal EHE and review existing literature on pulmonary EHE (PEH). CASE HISTORY: A 58 year-old gentleman presented to our outpatient Clinic with chest discomfort and palpitations...

Lung cancer is the leading contributor to morbidity and mortality from cancer worldwide, with its 5-year overall survival being only about 15.6%. Due to the lack of specific early screening methods for lung cancer, about 75% patients are diagnosed late. Therefore, it remains the big challenge for the early diagnosis of lung cancer. We need to pay more attention to the screening of lung cancer, and more precise assessment and management to the pulmonary nodules screened out. Further study on liquid biopsy, optimization of new fiberoptic bronchoscopy and the sampling methods to harvest small volume of lung tissue, could be helpful to improve the early diagnosis of lung cancer...

Cytomegalovirus (CMV) infection is a well-recognised complication of immunodeficiency, although the burden of CMV disease in immunocompetent adults is still unknown. We present the case of a 54-year-old male patient admitted due to severe diarrhoea, epigastric pain and fever. Initial diagnostic workup revealed pericardial and pleural effusion, enlarged abdominal lymph nodes and mild elevation of liver enzymes. CMV serology was IgM positive, and upper endoscopy revealed proximal enteritis. Histology and immunohistochemistry of duodenal samples confirmed CMV disease...

Granulomatosis with polyangiitis (GPA) is a systemic disease characterized by necrotizing, granulomatous vasculitis of the upper and lower respiratory tracts and glomerulonephritis, and is classified as a classical or limited form. The classical form of GPA demonstrates the involvement of the upper respiratory tract, sinuses, lungs and kidneys, whereas the limited form is characterized by the lack of the renal involvement with female predominance. On the other hand, mixed connective tissue disease (MCTD) shows the clinical and laboratorial features of systemic lupus erythematosus, systemic sclerosis and polymyositis, along with high titers of anti-ribonucleoprotein antibodies and is characterized by good response to corticosteroid therapy and favorable prognosis...

Lung cancer is primarily caused by cigarette smoking and the leading cancer killer in the USA and across the world. Early detection of lung cancer by low-dose CT (LDCT) can reduce the mortality. However, LDCT dramatically increases the number of indeterminate pulmonary nodules (PNs), leading to overdiagnosis. Having a definitive preoperative diagnosis of malignant PNs is clinically important. Using microarray and droplet digital PCR to directly profile plasma miRNA expressions of 135 patients with PNs, we identified 11 plasma miRNAs that displayed a significant difference between patients with malignant versus benign PNs...

In resource-limited countries, the diagnosis of pulmonary tuberculosis (TB) is based on clinical findings, chest radiography and the demonstration of acid-fast bacilli in sputum. Few data are available on the use of ultrasound (US) to diagnose pulmonary TB. Chest US was performed in patients with lung TB from a rural African setting, to look for signs of the disease and to clarify the role US may have in the diagnosis of pulmonary TB. Sixty adult patients diagnosed with lung TB underwent chest US. All patients had abnormal findings...

Genitourinary Tuberculosis (GUTB) is the second most common extra-pulmonary manifestation of tuberculosis (Tb) and an isolated involvement of genital organs is reported in 5-30% of the cases. Genital involvement results from primary reactivation of latent bacilli either in the epididymis or the prostate or by secondary spread from the already infected urinary organs. The epididymis are the commonest involved organs affected primarily by a hematogenous mode of spread. Tb is characterized by extensive destruction and fibrosis, thus an early diagnosis may prevent function and organ loss...
