BACKGROUND: Postoperative ipsilateral shoulder pain occurs in 37% to 68% of patients undergoing a thoracotomy. We examined whether interscalene brachial plexus block using a lower concentration of local anesthetic would reduce the incidence of post-thoracotomy ipsilateral shoulder pain with assessment of pulmonary function in patients who underwent a lung lobectomy. METHODS: Forty-four patients who underwent a lung lobectomy were randomly assigned to either the control or the interscalene block group...

BACKGROUND: Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has an excellent diagnostic yield, there remain cases where the diagnosis is not obtained. We hypothesized that additional sampling with a 19-G EBUS-TBNA needle may increase diagnostic yield in a subset of cases where additional tissue sampling was required. METHODS: Indications for use of the 19-G needle following 22-G sampling with rapid on-site cytologic examination were: (1) diagnostic uncertainty of the on-site cytopathologist (eg, nondiagnostic, probable lymphoma, etc...

BACKGROUND: Point of care bedside ultrasound is widely utilized as a rapid technique to evaluate patients with acute pulmonary emergencies, including acute pneumothorax. The presence of a pneumothorax is a known cause of loss of lung sliding by ultrasound examination, but no other risk factors have been clearly identified. We attempted to identify demographic and patient characteristics that are risk factors for loss of ultrasonographic lung sliding in the absence of a pneumothorax. METHODS: Data were collected on 159 patients admitted to the medical intensive care unit with acute respiratory failure, undergoing routine admission lung ultrasound...

BACKGROUND: The value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the mediastinal staging of lung cancer has been well established. However, data regarding its utility in the diagnosis of intrapulmonary lesions has been sparse. This study assesses the sampling utility of convex probe EBUS-visible intrapulmonary lesions not visualized by the white-light bronchoscopy. METHODS: A retrospective analysis of EBUS-TBNA of EBUS-visible intrapulmonary lesions was performed between January 2010 and March 2015...

BACKGROUND: Despite major advances in medical technology, the incidence of preterm birth remains high. The use of antenatal corticosteroid administered transplacentally, by intramuscular injection to women at risk of preterm birth, has reduced the incidence of respiratory distress syndrome and increased the survival rates of preterm infants. However, this intervention also comes with its own risks and side effects. Animal studies and early studies in pregnant women at risk of preterm birth have reported the use of an alternative route of administration, by direct intramuscular injection of corticosteroid into the fetus under ultrasound guidance, in an attempt to minimise the side-effect profile...

BACKGROUND: The limited negative predictive value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has often been discussed. OBJECTIVE: The aim of this study was to identify a highly sensitive molecular biomarker for lymph node staging by EBUS-TBNA. METHODS: Five microRNAs (miRNAs) (miR-200a, miR-200b, miR-200c, miR-141, and let-7e) were selected as biomarker candidates for the detection of nodal metastasis in a miRNA expression analysis...

Human immunodeficiency virus (HIV) infection is a major risk factor for the development of active tuberculosis (TB), one of the deadliest infectious diseases globally. The high mortality associated with the disease can be reduced by early diagnosis and prompt antituberculous treatment initiation. Facilities in TB-endemic regions are increasing the use of nucleic acid amplification (e.g., GeneXpert), which provides rapid results but may have suboptimal sensitivity in HIV-associated TB. Our objective was to evaluate the current practices for TB diagnosis at Edendale Hospital, a large regional hospital in KwaZulu-Natal, South Africa-a TB-endemic region with high HIV prevalence...

We present a case of a 76 year-old, non-smoking Honduran female who was referred to our clinic for years of persistent dry cough. Cardiac evaluation was unremarkable. She denied symptoms of heartburn, allergic rhinitis, and there was no personal or family history of asthma. Her physical exam demonstrated wheezing over the right mid-posterior chest. Spirometry was within normal limits. CT-imaging of the chest demonstrated right middle lobe bronchus and lingular segmental bronchus narrowing with bibasilar atelectasis and mild interlobular septal thickening with prominent mediastinal adenopathy...

The purpose of this case presentation is to discuss right upper quadrant pain as an atypical presenting symptom in pulmonary infarction and review the typical computed tomography (CT) imaging features of pulmonary infarction to improve diagnostic accuracy. Pulmonary infarction results from occlusion of distal arterial vasculature within the lung parenchyma leading to ischemia, hemorrhage, and ultimately necrosis. Patients with lung infarction typically present with pleuritic chest pain and may have associated signs or symptoms of pulmonary thromboembolism or deep vein thrombosis...

In this article we have presented a case of 31-year-old male with thickening of the skin and tender cord of superficial veins of the penis and laboratory findings of the high titer of PM/Scl-100 antibodies in the serum. The patient was referred to the Rheumatology Department due to suspected systemic sclerosis. The HRCT scan of his lungs revealed fibrous degeneration and ground-glass opacity in the lower lobes. Capillaroscopy showed abnormalities, which were not typical for systemic sclerosis. In Doppler ultrasound examination of penis, superficial dorsal and circumflex veins thrombosis and inflammatory infiltration were observed...

OBJECTIVES: The clinical diagnosis of pneumonia lacks specificity and may lead to antibiotic overuse, whereas radiological diagnoses can lack sensitivity. Point-of-care lung ultrasound is an emerging diagnostic tool. There are limited prospective data, however, on the accuracy of sonologists in the paediatric emergency department setting. We aimed to test the diagnostic accuracy of lung ultrasound for pneumonia using chest radiograph (CR) as the reference standard. METHODS: This prospective observational cohort study in a paediatric emergency department enrolled children aged 1 month to <18 years, who had a CR ordered for possible pneumonia...

AIM: B-lines count measured with lung ultrasound (LUS) quantifies extravascular lung water and is validated in the setting of acute cardiac failure or chronic dialysis. Patients are often kept in moderately overhydrated states during the early postoperative period following kidney transplantation (KT). We described congestion changes during the early postoperative period following KT and the feasibility of LUS in this setting. METHODS: LUS (28 scanning-points method) and inferior vena cava (IVC) measurements were routinely performed in 36 patients after KT...

PURPOSE: Optimal strategies to detect early interstitial lung disease (ILD) are unknown. ILD is frequently subpleural in distribution and affects lung elasticity. Lung ultrasound surface wave elastography (LUSWE) is a noninvasive method of quantifying superficial lung tissue elastic properties. In LUWSE a handheld device applied at the intercostal space vibrates the chest at a set frequency, and the lung surface wave velocity is measured by an ultrasound probe 5 mm away in the same intercostal space...

Progressive fibrobullous changes in the residual lobes are sometimes observed after lobectomy. Aspergillus osteomyelitis is an uncommon infection that rarely occurs sternally. A 70-year-old man who had undergone lobectomy 12 years earlier was admitted to our hospital for chest pain. He was diagnosed with Aspergillus sternomyelitis based on sternal bone culture after an ultrasound-guided percutaneous needle biopsy. The fibrosis and right residual lung apex volume loss had gradually progressed over 12 years, and therefore, chronic pulmonary aspergillosis (CPA) with direct invasion sternal from the CPA was considered...

The first perioperative transesophageal echocardiography (TEE) guidelines published 21 years ago were mainly addressed to cardiac anesthesiologists. TEE has since expanded its role outside this setting and currently represents an invaluable tool to assess chamber sizes, ventricular hypertrophy, and systolic, diastolic, and valvular function in patients undergoing orthotopic liver transplantation (OLT). Right-sided microemboli, right ventricular dysfunction, and patent foramen ovale (PFO) are the most common intra-operative findings described during OLT...

BACKGROUND: In the investigation of lung cancer, current practice in many healthcare systems would support bronchoscopy regardless of CT findings in patients with hemoptysis. We sought to identify the cause, the diagnostic yield of CT and bronchoscopy and the requirement for bronchoscopy in at risk patients with hemoptysis with a normal CT scan through our rapid access lung cancer clinic (RALC). METHODS: Initially, a chart review was performed on all patients with hemoptysis (2011-2012) and thereafter a prospective analysis was performed (2013-2016)...

Lung mass density is directly associated with lung pathology. Computed Tomography (CT) evaluates lung pathology using the Hounsfield unit (HU) but not lung density directly. We have developed a lung ultrasound surface wave elastography (LUSWE) technique to measure the surface wave speed of superficial lung tissue. The objective of this study was to develop a method for analyzing lung mass density of superficial lung tissue using a deep neural network (DNN) and synthetic data of wave speed measurements with LUSWE...
