BACKGROUND: It is well known that ultrasound-guided needle-aspiration (USGNA) for intrapulmonary subpleural lesion in contact with the pleura is useful and safe, and its diagnostic yield is high. However, reports concerned with the analyses of cases with intrapulmonary subpleural lesion which could not be diagnosed using USGNA are limited. The objective of this study is to clarify the radiological properties of subpleural primary lung cancer which obstruct diagnosis by USGNA. METHODS: The consecutive cases with subpleural primary lung cancer whose radiological properties could be confirmed by thoracic computed tomography (CT) without contrast enhancement (CE), and examined by USGNA at our hospital between January 1999 and December 2014 have been analyzed...

BACKGROUND: Birt-Hogg-Dubé syndrome (BHDS) is a recently recognized inherited multiple cystic lung disease causing recurrent pneumothoraces. Similarly to the lesions in patients with lymphangioleiomyomatosis (LAM), the pulmonary cysts are innumerable and widely dispersed and cannot all be removed. We recently described a total pleural covering (TPC) that covers the entire visceral pleura with oxidized regenerated cellulose (ORC) mesh. TPC successfully prevented the recurrence of pneumothorax in LAM patients...

Polyserositis (PS) is the inflammation, with effusion, of different serous membranes. It has been associated with different aetiologiesbut the aetiology of PS remains unknown in a high percentage of patients. The general objective of this retrospective study was to analyse the aetiology of PS cases seen at Son Llàtzer Hospital in an eleven-year period. Other objectives were to determine epidemiological, clinical, and analytical characteristics of these patients. Ninety-two patients were included in the study...

BACKGROUND: The Easy IJ procedure involves placement of a 4.8-cm intravenous catheter into the internal jugular (IJ) vein using ultrasound guidance. It is not known whether this needle length has the potential to cause a pneumothorax. OBJECTIVE: The objective of this study was to determine if a radiographic "safe margin" exists. We hypothesized that an average margin of ≥2 cm would exist between the catheter tip and the pleura. METHODS: Operators used a central approach to the IJ vein...

Pleuropulmonary Blastoma corresponds to a malignant primary lung disorder, exclusive of pediatric age, infrequent and of aggressive characteristics. Age on diagnosis is 1 month-12 years. Rates per sex are equal. It can be found inside pleura or lungs. Respiratory distress associated or not with pneumothorax, chest pain and fever are classical clinical signs. These symptoms could be misdiagnosed as pneumonia. Radiologically, a large mass near the pleura at the base of the right lung without air bronchogram is its most common form...

Histiocytic sarcoma (HS) is a rare malignant neoplasm showing morphological and immunophenotypic features of mature tissue histiocytes. As HS may mimic non-Hodgkin lymphoma (NHL) pathologically, before the era of immunohistochemistry, many previously reported cases were misdiagnosed NHL. Up to date, there are only a few reports delineating the cytological features in fine-needle aspiration or bronchoalveolar lavage, but not in the effusion fluid yet. Herein, we report the case of a 61-year-old male with a mediastinal tumor presenting with malignant pleural effusion...

A 44-year-old woman was referred to our hospital with pleural effusion and unknown fever. Mycobacterium tuberculosis was not detected by culture of pleural effusion and sputum and gastric fluid. Pleural fluid was serous and exudative, and cytological examination showed no malignant cells. Computed tomography revealed a little pleural thickening of the right middle lobe and massive pleural effusion. As acute pleurisy was suspected based on the findings of imaging studies, thoracoscopy was performed under general anesthesia...

BACKGROUND: The incidence of metachronous esophageal squamous cell cancer (ESCC) after head and neck cancer (HNC) and in elderly patients has increased. Both elderly ESCC patients and ESCC patients after HNC surgery are at potential risk for dysphagia, and for the latter, surgery in the neck is difficult. An intrathoracic anastomosis that bypasses the cervical procedure is preferable to preserve swallowing function and reduce surgical risk. In gastrectomized patients, because the stomach cannot be used as a substitute, securing graft blood supply is critical, but microvascular anastomosis cannot be easily added in procedures for intrathoracic posterior mediastinal reconstruction...

During video-assisted thoracic surgery (VATS), localization is sometimes needed to detect a target lesion that is too small and/or too far from the pleura. In 1995, Kanazawa et al. developed short hookwire and suture system. Since then, this system has been placed often for selected targets before VATS in Japan. This short hookwire and suture system is a representative preoperative localization method and the placement procedure is well-established. Its placement success rates are very high (range: 97.6%-99...

Upon inhalation, multi-walled carbon nanotubes (MWCNTs) may reach the subpleura and pleural spaces, and induce pleural inflammation and/or mesothelioma in humans. However, the mechanisms of MWCNT-induced pathology after direct intrapleural injections are still only partly elucidated. In particular, a role of the proinflammatory interleukin-1 (IL-1) cytokines in pleural inflammation has so far not been published. We examined the MWCNT-induced pleural inflammation, gene expression abnormalities, and the modifying role of IL-1α and β cytokines following intrapleural injection of two types of MWCNTs (CNT-1 and CNT-2) compared with crocidolite asbestos in IL-1 wild-type (WT) and IL-1α/β KO (IL1-KO) mice...

Background: To find small pulmonary nodules or ground grass nodules (GGNs) with video-assisted thoracoscopic surgery (VATS) is very difficult. There are several conventional methods to localize small nodules or GGNs, which require additional radiation exposure and may cause some complications such as pneumothorax or hemothorax. We aimed to evaluate the effectiveness and feasibility of electromagnetic navigational bronchoscopy-guided pulmonary localization in a minimally invasive thoracic surgery field...

INTRODUCTION: Although human intrapleural hyperthermic perfusion (HIHP) has achieved excellent palliative effects in metastatic pleural malignancies, the optimum treatment conditions, including inlet temperature and treatment times based on tumor size, have yet to be determined. However, such information is recognized to be critical for treatment planning in clinics. Therefore, the current research aimed to solve these issues. METHODS: Using the finite-element method (FEM), a simplified three-dimensional HIHP model was established and verified according to the temperature data of specific measuring points based on a clinical therapeutic case...

BACKGROUND: Thoracic paravertebral block is a technique for perioperative analgesia in patients undergoing thoracic, chest wall, or breast surgery, or for pain management with rib fractures, which can be performed with or without ultrasound guidance. The ultrasound guidance technique can be used to identify the thoracic paravertebral space, guide needle placement, monitor the spread of local anesthetic (LA) solution, and reduce complications such as pleural puncture and pneumothorax. The possibility of assessing anesthetic spread in real time using ultrasound guidance during paravertebral block offers numerous advantages, including the immediate and accurate identification of the extent of nervous block, with a consequent reduction of LA dose...

This study provides an understanding of the biokinetics and potential toxicology in the lung and pleura following inhalation of brake-dust (brakes manufactured with chrysotile). The design included a 28-day repeated multi-dose inhalation exposure (6 h/d, 5 d/wk, 4 wks) followed by 28-days without exposure. Fiber control groups included a similar grade chrysotile as used in the brakes and a commercial crocidolite asbestos. Aerosol fiber distributions of the chrysotile and crocidolite were similar (fiber-length > 20 μm/cm3 : Chrysotile-low/high 42/62; Crocidolite-low/high 36/55; WHO-fibers/cm3 : Chrysotile-low/high 192/219; Crocidolite-low/high 211/255)...
