AIMS: Combination of exogenous surfactant with antioxidant enzyme recombinant human superoxide dismutase (rhSOD) was tested in the treatment of experimental meconium aspiration syndrome as oxidative processes play key role in its pathogenesis. MATERIAL AND METHODS: Young New Zealand rabbits were instilled by saline (Sal group) or by meconium suspension (Mec group). Some of meconium-instilled animals were treated by surfactant alone (Surf group) or surfactant in combination with rhSOD (Surf + SOD group) and oxygen-ventilated for 5 h...

RATIONALE: An accurate assessment of the mediastinal lymph nodes status is essential in the staging and treatment planning of potentially resectable non-small cell lung cancer (NSCLC). OBJECTIVES: We performed this meta-analysis to evaluate the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in detecting occult mediastinal disease in NSCLC with no radiologic mediastinal involvement. METHODS: The PubMed, Embase, and Cochrane libraries were searched for studies describing the role of EBUS-TBNA in lung cancer patients with radiologically negative mediastinum...

The heterozygous PHOX2B gene mutation is related to congenital central hypoventilation syndrome (CCHS). It is characterized by defective autonomous nervous system development leading to inadequate breathing response to hypoxia and hypercapnia, leading to hypoventilation especially during non-REM sleep, but also during waking in the more severe cases. Herein we report a case of sudden death in a 28-day-old child. The mother reported the infant was found lying on her own bed in the prone position. The infant was wearing a romper and lying in her crib without any blanket or other objects...

RATIONALE: Multiwalled carbon nanotubes (MWCNTs) are a potential risk for pulmonary fibrosis because of their fiber-like shape; other physicochemical features, such as rigidity, could also confer fibrogenicity. The signal transducer and activator of transcription 1 (STAT1) is an important antifibrogenic transcription factor that promotes fibroblast growth arrest. STAT1-deficient (Stat1-/- ) mice are susceptible to pulmonary fibrosis. OBJECTIVES: In this study, we hypothesized that Stat1-/- mice exhibit a differential fibrogenic response to tangled MWCNTs versus rigid MWCNTs above that seen with wild-type (Stat1+/+ ) mice...

Despite recent advances in screening methods, lung cancer remains the leading cause of cancer-related deaths worldwide. By the time lung cancer becomes symptomatic and patients seek treatment, it is often too advanced for curative measures. Low-dose computed tomography (CT) screening has been shown to reduce mortality in patients at high risk of lung cancer. We present a 66-year-old man with a 50-pack-year smoking history who had a right upper lobe (RUL) pulmonary nodule and left lower lobe (LLL) consolidation on a screening CT...

Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung...

Lung cancer is one of the most frequent neoplastic diseases. To date, most lung cancer is diagnosed at an advanced stage, making it difficult to choose the diagnostic and therapeutic strategy. Surgical resection represents the best therapeutic solution. However, the best results are obtained only in the early stages of the disease. Lymph node involvement conditions the treatment (surgical or non-surgical approach). Mediastinoscopy is an effective and widely used method for mediastinal staging but does not allow us to reach many mediastinal lymph nodes...

BACKGROUND: Rescue ventilations are given during respiratory and cardiac arrest. Tidal volume must assure oxygen delivery; however, excessive pressure applied to an unprotected airway can cause gastric inflation, regurgitation, and pulmonary aspiration. The optimal technique provides mouth pressure and breath duration that minimize gastric inflation. It remains unclear if breath delivery should be fast or slow, and how inflation time affects the division of gas flow between the lungs and esophagus...

Extranodal lymphomas involve adrenal glands as a mass lesion in 3% to 5% of cases as identified by imaging studies. Definitive diagnosis of the neoplasm is provided by morphological and immunophenotypical evaluation on limited tissue obtained by fine needle aspiration or core biopsy. We report a diagnostically challenging case that presented as masses involving adrenal gland and lung in the setting of a concurrent primary renal cell carcinoma. PAX8, a frequently used marker for renal cell carcinoma, was immunoreactive in the neoplastic cells of the adrenal mass, and thus highly suggestive for metastatic renal cell carcinoma...

BACKGROUND: Bronchoscopic techniques can be used to safely sample peripheral lung nodules (PLN), and transbronchial needle aspiration (TBNA) can further increase the diagnostic yield. Current needle devices not necessarily designed for this indication have limitations. We report our initial experience with a new flexible nitinol peripheral TBNA needle specifically designed for such sampling. METHODS: Retrospective case review describing the first clinical cases performed with a commercially available 21-G peripheral TBNA device in 4 centers...

Medullary thyroid carcinoma occurs in a sporadic setting and may also be inherited in an autosomal dominant fashion, which is related with germline mutations of the RET gene. Metastases are often present at the time of a diagnosis-most frequently within the cervical lymph nodes, followed by the liver, lungs, and bones. Intraocular metastases are extremely rare. We present a case of choroidal metastasis as a first presentation of disease progression in a patient with Multiple Endocrine Neoplasia type 2A syndrome (MEN2A) who had undergone thyroidectomy 33 years earlier for medullary thyroid carcinoma...

We report a very rare case of pulmonary chromomycosis caused by Scedosporium prolificans that developed after lung transplantation and was successfully treated with endobronchial topical amphotericin B instillation. The subject was a woman in her 50s with a history of bilateral lobar lung transplantation from living donors for idiopathic pulmonary hypertension. Eight years after the lung transplantation, chest radiography X-ray and computed tomography showed an abnormal shadow in the right lung. Bronchoscopic findings showed obstruction by a fungal component at the laterobasal bronchus B9...

BACKGROUND: Transbronchial needle aspiration (TBNA), often used to sample lymph nodes for lung cancer staging, is subject to sampling error even when performed with endobronchial ultrasound. Optical coherence tomography (OCT) is a high-resolution imaging modality that rapidly generates helical cross-sectional images. We aim to determine if needle-based OCT can provide microstructural information in lymph nodes that may be used to guide TBNA, and improve sampling error. METHODS: We performed ex vivo needle-based OCT on thoracic lymph nodes from patients with and without known lung cancer...

The aim of this work was to study the antifibrotic effect of pulmonary administration of tilorone to lung fibrosis. L-leucine coated tilorone particles were prepared and their aerosolization properties were analyzed using two dry powder inhalers (Easyhaler and Twister). In addition, the biological activity and cell monolayer permeation was tested. The antifibrotic effect of tilorone delivered by oropharyngeal aspiration was studied in vivo using a silica-induced model of pulmonary fibrosis in mice in a preventive setting...

A 76-year-old female underwent breast-conserving surgery of the right breast and sentinel lymph node biopsy for primary breast cancer. Three years later, mammography and ultrasonography showed a small nodule in the right breast. There was nothing abnormal in the left breast. Three months later, she complained of a huge and rapid growing mass in the left breast. Malignant cells were obtained on fine needle aspiration biopsy in the right breast tumor. But it was not possible to diagnose whether the left breast tumor was benign or malignant on fine needle aspiration biopsy and needle biopsy...

Mesenchymal stromal cells (MSCs) are released into the airways of preterm infants following lung injury. These cells display a pro-inflammatory phenotype and are associated with development of severe bronchopulmonary dysplasia (BPD). We aimed to characterize the functional properties of MSCs obtained from tracheal aspirates of 50 preterm infants who required invasive ventilation. Samples were separated by disease severity. The increased proliferative capacity of MSCs was associated with longer duration of mechanical ventilation and higher severity of BPD...
