With improved awareness of public health and the recent advances in various imaging technologies, the detection rate of solitary pulmonary nodules (SPN) is continuously increasing. Transthoracic needle aspiration (TTNA) has represented a major approach for the diagnosis and differential diagnosis of pulmonary masses, owing to its simplicity and minimal invasiveness. This paper demonstrates the role of TTNA in SPN.

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

Background Soluble receptor for advanced glycation end-products (sRAGE), a soluble isoform of the RAGE receptor, is elevated in lungs from patients with acute conditions such as acute respiratory distress syndrome and bronchiolitis. This study investigated whether sRAGE is present in ventilated infants. Methods Tracheal aspirates from the first week or the fifth week of life were obtained from intubated very low birth weight subjects and analyzed by Western blot. Immunohistochemistry analysis for sRAGE was performed on paraffin-embedded lung autopsy slides from 19 other infants...

We report a case with suggestive antiprogrammed death-1 inhibitor-related pneumonitis in an endometrial cancer patient. This case presented with fever and cough after three dosages of nivolumab. Computed tomography initially showed centrilobular nodularities in a unilateral lung, which was compatible with aspiration pneumonia. However, diffuse ground-glass opacities (GGO) rapidly developed in the unilateral lung over 4 days despite the use of broad-spectrum antibiotics. Development of GGO was considered to be related to a nivolumab-mediated immune reaction...

Cervical chylomas are rare pseudocystic collections that lack an epithelial lining and arise from the thoracic duct or its tributaries; although they typically develop after neck surgery or trauma, they can arise from unknown causes. Treatment options include not only conservative therapy, such as dietary modification, repeated aspirations, and sclerotherapy, but also include surgical excision. We describe a case of a chyloma in a 64-year-old Japanese woman with squamous cell carcinoma of the gingiva. The chyloma developed following left segmental mandibulectomy with radical neck dissection and reconstruction, using a titanium plate and a pectoralis major myocutaneous flap...

Acid pneumonitis is a major cause of sterile acute lung injury (ALI) in humans. Acid pneumonitis spans the clinical spectrum from asymptomatic to acute respiratory distress syndrome (ARDS), characterized by neutrophilic alveolitis, and injury to both alveolar epithelium and vascular endothelium. Clinically, ARDS is defined by acute onset of hypoxemia, bilateral patchy pulmonary infiltrates and non-cardiogenic pulmonary edema. Human studies have provided us with valuable information about the physiological and inflammatory changes in the lung caused by ARDS, which has led to various hypotheses about the underling mechanisms...

Zinc oxide nanoparticles (ZnONPs) are widely used in our daily life, such as in sunscreens and electronic nanodevices. However, pulmonary exposure to ZnONPs causes acute pulmonary inflammation, which is considered as an initial event for various respiratory diseases. Thus, elucidation of the underlying cellular mechanisms of ZnONPs can help us in predicting their potential effects in respiratory diseases. In this study, we observed that ZnONPs increased proinflammatory cytokines, accompanied with an increased expression of aryl hydrocarbon receptor (AhR) and its downstream target cytochrome P450 1A1 (CYP1A1) in macrophages in vitro and in mouse lung epithelia in vivo...

OBJECTIVE: To compare a series of monomicrobial Propionibacterium acnes (P. acnes) knee and hip periprosthetic joint infection (PJI) cases with cases of polymicrobial PJI which included P. acnes. We hypothesized that the presence of a polymicrobial P. acnes infection would lead to worse outcomes than those in cases of monomicrobial P. acnes PJI. METHODS: Retrospective multicentre study. All patients with hip or knee PJIs including P. acnes diagnosed from August-2002 to July-2013 in two university hospitals were included...

OBJECTIVE: To assess the cost-effectiveness of various modes of mediastinal staging in non-small cell lung cancer (NSCLC) in a single-payer health care system. METHODS: We performed a decision analysis to compare the health outcomes and costs of 4 mediastinal staging strategies: no invasive staging, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), mediastinoscopy, and EBUS-TBNA followed by mediastinoscopy if EBUS-TBNA is negative. We determined incremental cost effectiveness ratios (ICER) for all strategies and performed comprehensive deterministic sensitivity analyses using a willingness to pay threshold of $80,000/quality adjusted life year (QALY)...

BACKGROUND: The rates of resection of nonmalignant lung nodules suspected preoperatively to be lung cancer vary widely and are reported to be as high as 40%. We determined the impact of the frequent use of computed tomography (CT)-guided fine needle aspiration (FNA) on the resection rate of nonmalignant nodules and frequency of resections of benign disease among patients undergoing evaluation for lung cancer resection operation in an academic medical center. METHODS: Eligible patients underwent CT-guided FNA, surgical resection, or both during the 12-month period between July 2013 and July 2014 for known or suspected first primary resectable stage I-III lung cancer...

BACKGROUND: Mesenchymal stem cells (MSCs) might act as fine-tuners of inflammation during acute lung injury. We assessed the effects of adoptive transfer of MSCs in acid aspiration acute lung injury and explored the role of long pentraxin PTX3. METHODS: We conducted a prospective experimental interventional study on wild-type (WT) and PTX3-deficient (PTX3(-/-)) mice. Acute lung injury was induced in WT and PTX3(-/-) mice by instillation of hydrochloric acid into the right bronchus...

Paragangliomas are rare neoplasms that arise from neural crest cells of the autonomous system. Herein, we present a case of a 37-year-old patient with a history of retroperitoneal paraganglioma and tuberculous infection presenting with a paraganglioma of the neck that was initially misdiagnosed as metastatic tumor originating from the lungs. Cytological features from fine needle aspiration and immunocytochemistry pointed to the right diagnosis. However, distinguishing between primary and metastatic site of a paraganglioma can be very challenging due to the overlapping features of these entities...

PURPOSE: Mechanically ventilated patients are at risk for developing ventilator-associated pneumonia, and it has been reported that dental plaque provides a reservoir of respiratory pathogens that may aspirate to the lungs and endotracheal tube (ETT) biofilms. For the first time, metataxonomics was used to simultaneously characterize the microbiome of dental plaque, ETTs, and non-directed bronchial lavages (NBLs) in mechanically ventilated patients to determine similarities in respective microbial communities and therefore likely associations...

BACKGROUND: Patients sometimes require insertion of a nasogastric tube for the administration of a large volume of a polyethylene glycol electrolyte solution. If the tube is malpositioned, the risk for direct instillation of the solution into the lung increases. The risk for aspiration also increases if the infusion rate exceeds gastrointestinal tolerance. PURPOSE: To review published cases of patients' experiencing adverse pulmonary events after administration of polyethylene glycol electrolyte solution via a nasogastric tube and to offer suggestions to prevent these outcomes...

Lung carcinoma is the main cause of cancer death worldwide. Adenocarcinoma molecular biomarkers have been discovered, and targeted therapies have been developed with encouraging results. The epidermal growth factor receptor gene is one of these biomarkers. Exons 18 to 21 should be studied in patients with advanced adenocarcinoma, who are candidates for treatment with tyrosine kinase inhibitors. The objective was to compare the performance of the determination in large and small samples in daily practice conditions, trying to adjust to published consensus guidelines...
