Low-dose computed tomography (LDCT) screening has increased the detection rate for small pulmonary nodules with ground-glass opacity (GGO) in the peripheral lung parenchyma. Minimally invasive thoracoscopic surgery for these lung nodules is challenging for thoracic surgeons, and image-guided preoperative localization is mandatory for their successful resection. Image-guided localization methods primarily include two imaging tools: computed tomography (CT) and bronchoscopy. These different methods may use different localized materials, including hookwires, dyes, microcoils, fiducial markers, contrast media, and radiotracers...

The advancement of imaging technology has recently facilitated single port minimally-invasive thoracic surgery techniques. Cone-beam computed tomography (CBCT) shows promising results in visualizing the target lesion and its surrounding critical anatomy, with an error of less than 2 mm. The integration of CBCT with the operating room (OR) to form the hybrid OR, provides unparalleled real-time imaging of the patient, which can be used with electromagnetic navigation bronchoscopy to confirm successful navigation and increase procedural accuracy particularly for small peripheral pulmonary targets...

BACKGROUND: Transbronchial biopsy (TBB) using radial endobronchial ultrasound with a guide sheath (REBUS-GS) has improved the diagnosis of peripheral pulmonary lesions (PPLs). Because of the high cost of the GS, REBUS with distance (REBUS-D) has certain advantages. The aim of this study was to compare the diagnostic yield of the REBUS-GS and REBUS-D by thin bronchoscopy for PPLs. METHODS: Patients with PPLs were enrolled in a prospective randomized crossover study from August 2014 and July 2015...

BACKGROUND: Osteosarcoma (OS) and Ewing sarcoma (ES) have a high propensity to develop pulmonary metastases. Lung lesions with calcification, peripheral location, and size >5 mm are more likely to represent malignant metastases. We evaluated the incidence of malignancy in nodules 5 mm or less to potentially guide decisions between biopsy and observation. MATERIALS AND METHODS: A retrospective review of patients <25 years of age with metastatic OS and ES treated at our institution between 2001 and 2014 who had undergone pulmonary nodule biopsy was performed...

The ability to reach the peripheral pulmonary nodule/mass with bronchoscopy has improved greatly over the past several years with the use of Electromagnetic navigational bronchoscopy; however, many of these lesions are unable to be adequately sampled due to their location outside the bronchial airways. We report the first use of the transbronchial access tool that creates a pathway from the bronchial airway through the lung parenchyma into the targeted lung abnormality.

Observation of major pathological alterations in a young person involves etiological and clinical justifications, in order to properly assess, treat and control these conditions. The aim of this paper is to present severe, acute pathological lesions, installed in a young person, secondary to hypodiastolic heart failure, due to persistent supraventricular tachyarrhythmia, triggered by a post-traumatic external stimulus, with complete remission post-electrical conversion. Pathological and clinical modification are revealed, in a young person, shortly after a minor thoracic trauma, in the absence of traumatic injury but with high-frequency palpitations onset and progressive installation of vascular, visceral and interstitial stasis modifications, as well as of vascular and tissular hypoperfusion with reactive vasoconstriction...

We report a case of invasive candidiasis presenting as multiple lung nodules and cavitary lesions with minimal pleural effusion. Candida infections of the lung are rare but can occur after hematologic dissemination of the yeast from other body sites, such as the skin and the gastrointestinal and genitourinary tracts. Here, we describe the case of a 56-year-old female with a history of end-stage renal disease (ESRD) who presented with fever, productive cough, and pulmonary nodules and cavitary lesions seen on a chest computed tomography (CT)...

BACKGROUND: Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. METHODS: Three sets of opaque soft copper wires visible under the fluoroscopy (Flu) in the Flu-flexible bronchoscopy (FB) group (n = 24), which determined the three planes of the lesion, were respectively placed firmly on the surface of the chest wall with adhesive tape on the chest wall...

BACKGROUND: Pulmonary cryptococcosis (PC) was not a rare infectious disease in non-AIDS patients. However, data on the immune status were lacking in southern China for comparative analysis of differences between immunocompromised and immunocompetent hosts. This study was to investigate the epidemiological, clinical, radiological, and treatment profiles for patients with PC. METHODS: We performed a retrospective review of 88 patients diagnosed with tissue-confirmed PC who were not HIV-infected from 2003 to 2013...

BACKGROUND: Computed tomography guided transthoracic needle aspiration (CT-TTNA) and endobronchial ultrasonography with guide sheath (EBUS-GS) transbronchial lung biopsy are important methods for the diagnosis of peripheral pulmonary lesions (PPLs). Without enough evidence, it is controversial which is a better choice for diagnosing PPLs. In this study, we hypothesized that the complication rate of EBUS-GS would be lower than CT-TTNA and the diagnostic accuracy of EBUS-GS were not inferior to CT-TTNA...

Bone metastases occur in over 75% of patients with advanced breast cancer and are responsible for high levels of morbidity and mortality. In this study, ex vivo expanded cytotoxic Vγ9Vδ2 T cells isolated from human peripheral blood were tested for their anti-cancer efficacy in combination with zoledronic acid (ZOL), using a mouse model of osteolytic breast cancer. In vitro, expanded Vγ9Vδ2 T cells were cytotoxic against a panel of human breast cancer cell lines, and ZOL pre-treatment further sensitised breast cancer cells to killing by Vγ9Vδ2 T cells...

A 12-year-old boy with a right atrium endocardial mass was initially diagnosed as having Lemierre's syndrome on the basis of previous mastoiditis and jugular vein and cerebral venous thrombosis. Lack of response to antibiotics, persistent high fever with chills, acute-phase reactants, and peripheral arterial pseudoaneurysms made us reconsider the diagnosis. Only after the late appearance of radiological pulmonary lesions and recognition of pulmonary artery aneurysms, Hughes-Stovin syndrome was diagnosed. Hughes-Stovin syndrome is an exceedingly rare vasculitis, especially in childhood, consisting of multiple pulmonary artery aneurysms and deep venous thromboses...

Objective: Conventional bronchoscopy has a low diagnostic yield for peripheral pulmonary lesions. Radial-probe EBUS employs a rotating ultrasound transducer at the end of a probe that is passed through the working channel of the bronchoscope. Radial-probe EBUS facilitates the localization of peripheral pulmonary nodules, thus increasing the diagnostic yield. The objective of this study was to present our initial experience using radial-probe EBUS in the diagnosis of peripheral pulmonary lesions at a tertiary hospital...
