Fontan circulation is the consequence of an operation that results in the flow of systemic venous blood to the lungs without passing through a ventricle. An 18-year old man with a history of congenital heart disease surgically treated with Fontan circulation, presented with pleuritic chest pain and a raised D-dimer level. Perfusion/ventilation SPECT was performed to exclude the possibility of pulmonary embolism (PE) that showed unilateral reduced perfusion of the left lung with a mismatched right upper lobe defect, suspicious of PE...

In rapidly deteriorating patients awaiting lung transplantation (LT), supportive strategies are only temporary and Urgent LT (ULT) remains the last option. The few publications on this topic report conflicting results. According to the Italian national program, patients on mechanical ventilation and/or extracorporeal membrane oxygenation may be included in urgent list. We reviewed our experience from January 2012 to December 2014 with ULT and Elective LT (ELT), focusing on outcomes. In the study period, 16 patients received ULT, while 51 received ELT...

Ventilation-perfusion scintigraphy (VPS) depicts the two main physiological processes that are fundamental to oxygen-dependent life. The test has affirmed its critical place in the evaluation of patients with lung cancer preparing for lung resection. The results of the study can differentiate patients who are very likely to survive surgery and the subsequent pulmonary function loss from those who are not. This review presents validated and evolving testing techniques for this critical indication. VPS has long been an integral part of the preoperative evaluation of lung transplant candidates, guiding the single lung grafts to the side with the worst function...

As precision medicine is becoming standard of care to select tailored rather than average treatments, physiological measurements might represent the first step to apply personalized therapy in the intensive care unit (ICU). Systematic assessment of respiratory mechanics in patients with the acute respiratory distress syndrome (ARDS) could represent a step towards this direction for two main reasons. On the one hand, respiratory mechanics are a powerful physiological method to understand the severity of this syndrome in each single patient...

BACKGROUND/PURPOSE: Lung transplantation in Taiwan began in 1991, but the experience was limited and diverse in the early years. We examined the cumulative institutional experience of the largest lung transplant cohort in Taiwan. METHODS: A retrospective review of lung transplantations performed at a single institution from December 1995 through August 2016 was conducted. For comparative purposes, the cohort was divided into halves, with an early group (undergoing lung transplantation in the first decade) vs a late group (undergoing lung transplantation in the second decade)...

BACKGROUND: Allergy and asthma are closely linked. Inhalation of allergen induces an early allergic response (EAR) within the airways of allergic asthmatic subjects, which is followed by a late allergic response (LAR) in approximately 50% of the subjects. The LAR is defined as a drop in forced expiratory volume in 1 s (FEV1 ) from baseline usually occurring 4-8 h after exposure, and is believed to affect small airways. However, FEV1 is insensitive to changes in small airway physiology...

How termite mounds function to facilitate climate control is still only partially understood. Recent experimental evidence in the mounds of a single species, the south Asian termite Odontotermes obesus, suggests that the daily oscillations of radiant heating associated with diurnal insolation patterns drive convective flow within them. How general this mechanism is remains unknown. To probe this, we consider the mounds of the African termite Macrotermes michaelseni, which thrives in a very different environment...

Arterial oxygen partial pressure can increase during inspiration and decrease during expiration in the presence of a variable shunt fraction, such as with cyclical atelectasis, but it is generally presumed to remain constant within a respiratory cycle in the healthy lung. We measured arterial oxygen partial pressure continuously with a fast intra-vascular sensor in the carotid artery of anaesthetized, mechanically ventilated pigs, without lung injury. Here we demonstrate that arterial oxygen partial pressure shows respiratory oscillations in the uninjured pig lung, in the absence of cyclical atelectasis (as determined with dynamic computed tomography), with oscillation amplitudes that exceeded 50 mmHg, depending on the conditions of mechanical ventilation...

BACKGROUND: With a mortality estimated at 25% when missed, diaphragmatic injuries due to penetrating thoracoabdominal trauma present a diagnostic challenge for both the radiologist and the surgeon. In the current literature, chest x-ray has a sensitivity of 27-60% for left-sided injuries and only 17% for right-sided injuries while, CT scan has a sensitivity of 14-61% and a specificity of 76-99%. Thoracoscopy using a single lung ventilation is one of the modalities of choice for the diagnosis of these injuries with a specificity of 100% and a sensitivity of 87...

The obesity rate is increasing worldwide and the percentage of obese patients in the intensive care unit (ICU) is rising concomitantly. Ventilatory support strategies in obese patients must take into account the altered pathophysiological conditions. Unfortunately, prospective randomized multicenter trials on this subject are lacking. Therefore, current strategies are based on the individual experiences of ICU physicians and single-center studies. Noninvasive ventilation (NIV) in critically ill patients with acute respiratory failure and obesity hypoventilation syndrome (OHS) is an efficient treatment option and should be provided as early as possible is an effort to avoid intubation...

PURPOSE: To provide updated radiation dose from diagnostic exams performed for pregnant patients suspected of pulmonary embolism (PE) using the recently developed BREP phantoms of pregnant woman and the fetus. Also to challenge the validity of current recommendations suggest that ventilation/perfusion (V/Q) single photon emission computed tomography (SPECT) vs. computed tomography pulmonary angiography (CTPA) should be considered for diagnosis of PE in radiosensitive groups such as pregnant women...

Abnormal pulmonary function is prevalent in survivors of allogeneic hematopoietic cell transplantation (HCT). Post-transplantation recovery of pulmonary function, and its effect on survival, in children are not known. This retrospective cohort study of 308 children followed for 10 years after HCT at a single institution included 2 groups of patients. Group 1 comprised 188 patients with 3 or more pulmonary function test (PFT) results, of which at least 1 was abnormal, and group 2 comprised 120 patients with 3 or more PFTs, all of which were normal...

Several factors have been recognized as possible triggers of ventilator-induced lung injury (VILI). The first is pressure (thus the 'barotrauma'), then the volume (hence the 'volutrauma'), finally the cyclic opening-closing of the lung units ('atelectrauma'). Less attention has been paid to the respiratory rate and the flow, although both theoretical considerations and experimental evidence attribute them a significant role in the generation of VILI. The initial injury to the lung parenchyma is necessarily mechanical and it could manifest as an unphysiological distortion of the extracellular matrix and/or as micro-fractures in the hyaluronan, likely the most fragile polymer embedded in the matrix...

INTRODUCTION: Advances in knowledge regarding mechanical ventilation (MV), in particular lung-protective ventilation strategies, have been shown to reduce mortality. However, the translation of these advances in knowledge into better therapeutic performance in real-life clinical settings continues to lag. High-fidelity simulation with a mannequin allows students to interact in lifelike situations; this may be a valuable addition to traditional didactic teaching. The purpose of this study is to compare computer-based and mannequin-based approaches for training residents on MV...

Since 1995, video-assisted thoracoscopic oesophagectomy (VATS), according the same surgical principles as the Japanese open surgery, has been completed in 700 patients with oesophageal cancer. Our indication for VATS is (I) no extensive pleural adhesion; (II) no contiguous tumor spread; (III) pulmonary function capable of sustaining single-lung ventilation, and (IV) non radiated patients. We use 4 ports around a 5 cm mini-thoracotomy on 5th intercostal space. We laid emphasis on utilizing magnifying effect of video (5 to 20 magnifications), obtained by positioning the camera at close vicinity to the dissection...
