BACKGROUND: Emphysema is one of the most common lung diseases in HIV+ individuals. The pathogenesis of HIV-associated emphysema remains unclear; however, radiographic distribution and earlier age of presentation of emphysema in the lungs of HIV+ patients are similar to deficiency of alpha-1 antitrypsin (A1AT), a key elastase inhibitor in the lung. Reduced levels of circulating A1AT have been detected in HIV+ patients, suggesting a potential mechanism for emphysema development. In the present study, we asked if A1AT levels and activity in the bronchoalveolar lavage fluid (BALF) differ in patients with and without HIV and emphysema...

BACKGROUND: Treatment of pleural infection with instillation of sequential intrapleural tissue plasminogen activator (tPA) and human recombinant deoxyribonuclease (DNase) twice daily for a total of 6 doses has been shown to decrease surgical referral and improve radiographic imaging. This labor-intensive regimen was empirically chosen. Thus, it remains unclear whether the 2 drugs can be administered immediately one after the other (concurrent administration) instead of instilling them separately with a 1-hour to 2-hour interval in between (sequential administration)...

BACKGROUND: Tuberculosis and cryptococcosis co-infection usually occurs in immunosuppressed patients with impaired cell-mediated immunity. However, there are few reports about such co-infection in non-HIV patients without underlying diseases. Here, we report a case of miliary tuberculosis with co-existing pulmonary cryptococcosis in non-HIV patient without underlying diseases. CASE PRESENTATION: An 84-year-old Asian female presented to our hospital with complaints of a 1-week history of abdominal pain and appetite loss...

Chest tomosynthesis (CTS) is a newly developed imaging technique which provides pseudo-3D volume anatomical information of thorax from limited-angle projections and contains much less of superimposed anatomy than the chest X-ray radiography. One of the relatively common problems in CTS is the patient respiratory motion during image acquisition, which negatively impacts the detectability. In this work, we propose a sin-quadratic model to analyze the respiratory motion during CTS scan, which is a real time method where the respiratory signal is generated by extracting the motion of diaphragm from projection radiographs...

Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disorder recently included in rare idiopathic interstitial pneumonias according to the updated American Thoracic Society/European Respiratory Society classification. IPPFE is characterized by pleural and subpleural parenchymal fibrosis causing volume loss predominantly in the upper lung lobes. Age of onset is variable, IPPFE mainly occurs in third and fourth decades. We present a 16 year old patient with a 2-year history of exertional dyspnea, nonproductive cough and weight loss...

BACKGROUND: Opinions differ as to the need of a lateral radiograph for diagnosing community acquired pneumonia in children referred to the emergency department. A lateral radiograph increases the ionizing radiation burden but at the same time may improve specificity and sensitivity in this population. OBJECTIVES: To determine the value of the frontal and lateral chest radiographs compared to frontal view stand-alone images for the management of children with suspected community acquired pneumonia seen in a pediatric emergency department...

We report a case of bilateral pulmonary infiltrates and haemoptysis following low-voltage electricity exposure in an agricultural worker. A 58-year-old man standing in water reached for an electric watering machine and sustained an exposure to 220 V circuit for an uncertain duration. The electricity was turned off by another worker, and the patient was asymptomatic for the next 10 h until he developed haemoptysis. A chest radiograph demonstrated bilateral infiltrates, and chest computed tomography (CT) revealed ground-glass opacities with interstitial thickening...

We developed a functional digital radiography system that provides physiological and functional information of the chest and/or joints using an X-ray flat-panel detector (FPD) system. During chest examination, sequential chest radiographs are taken from inspiration to expiration in order to analyze diaphragmatic movements. Pixel value changes in localized areas of the lung are then assessed to analyze ventilation and circulation. For limb joints, such as the wrist, shoulder, and knee, sequential radiographs during flexion and extension or rotational movement are considered, and movement angles are analyzed...

Background: Patients with small pneumothoraces are usually treated with oxygen therapy. However, evidence that oxygen therapy increases resolution rate is based on small populations with secondary spontaneous pneumothorax. Therefore, this study aimed to confirm whether oxygen therapy increases the resolution rate of primary spontaneous pneumothorax (PSP). Methods: We retrospectively reviewed records of patients with PSP who had undergone outpatient observation (room air group) and those who were admitted for oxygen therapy (O2 group) between March 2005 and February 2016...

RATIONALE: Complex pelvic ring fracture associated with floating knee is comparatively rare which usually results from high-energy trauma including vehicle-related accidence, falls from height, and earthquake-related injury. To our knowledge, few literatures have documented such injuries in the individual patient. Management of both injuries present challenges for surgical management and postoperative care. The purpose of this study is to prove the feasibility and benefits of damage control orthopedics (DCO)...

A 45-year old man with intermittent dyspnea was found to have a large mediastinal mass on chest radiograph. Computerized tomography scan revealed a 14.7 cm anterior mediastinal mass with cystic and solid components. The patient underwent a thoracoscopic resection of the mass without complication. Techniques utilized during this surgery may be helpful in avoiding pitfalls for other surgeons.

Background and Aims: The external jugular vein (EJV), often used for resuscitation, has been underutilised for central venous catheterisation (CVC) in view of an unpredictable success rate. There is an encouraging literature on the improved success rate of CVC through EJV with the inclusion of certain body manoeuvres. This prospective randomised controlled study was conducted with the aim of evaluating the efficacy of body manoeuvres in improving the success rate of CVC through EJV. Methods: One hundred patients aged 18-50 years, scheduled for elective surgery requiring CVC, were randomly assigned to either undergo CVC using Seldinger technique with body manoeuvres or a control group undergoing CVC without body manoeuvres...

BACKGROUND: Hemothorax is most commonly resulted from a closed chest trauma, while a tube thoracostomy (TT) is usually the first procedure attempted to treat it. However, TT may lead to unexpected results and complications in some cases. The advantage of thoracic ultrasound (TUS) over a physical examination combined with chest radiograph (CXR) for diagnosing hemothorax1 has been proposed previously. However, its benefits in terms of avoiding non-therapeutic TT have not yet been confirmed...

Introduction: Globally, Xpert MTB/RIF (Xpert) is the most widely-used PCR test for tuberculosis (TB). Positive results in previously-treated patients, which are due to old DNA or active disease, are a diagnostic dilemma.Materials and methods: We prospectively re-tested sputum from 238 patients, irrespective of current symptoms, who were previously-diagnosed as Xpert-positive and treated successfully. Patients who re-tested as Xpert-positive, culture-negative were exhaustively investigated (repeated culture, chest radiography, bronchoscopy with bronchoalveolar lavage, long-term clinical follow-up)...
