BACKGROUND: Endotracheal tube placement is necessary for the control of the airway in patients who are mechanically ventilated. However, prolonged duration of endotracheal tube placement contributes to the development of ventilator-associated pneumonias (VAPs). The aim of this study was to evaluate whether subglottic suctioning using TaperGuard EVAC tubes was effective in decreasing the frequency of VAP. METHODS: A total of 276 mechanically ventilated patients for more than 72 hours were randomly assigned to group E (EVAC tube) and group C (conventional tube)...

The purpose of this report is to describe a minimally invasive alternative endovascular technique for the treatment of chronically occluded stents when it is not possible to cross them endoluminally. A 71-years-old patient with recurrent severe lower limb claudication due to occlusion of a stent placed in the common iliac artery 5 years earlier underwent subintimal recanalization of the stented segment and re-stenting after failed intraluminal approach. The postoperative CT scan showed that the re-stented segment was patent with a flattening of the previous stent...

Burn injury is associated with a loss of gut barrier function, resulting in systemic dissemination of gut-derived bacteria and their products. The bacterial protein and TLR5 agonist, flagellin, induces non-specific innate immune responses. Because we detected flagellin in the serum of burn patients, we investigated whether gut-derived flagellin was a primary or secondary contributor to intestinal dysfunction and systemic inflammation following burn injury. The apical surface of polarized human intestinal epithelial cells (IECs), Caco-2BBe, were exposed to 50 or 500 ng of purified flagellin and 1 x 105 of an intestinal E...

Ricardo Espinoza González
Gastrointestinal bezoars are a concretion of indigested material that can be found in the gastrointestinal tract of humans and some animals. This material forms an intraluminal mass, more commonly located in the stomach. During a large period of history animal bezoars were considered antidotes to poisons and diseases. We report a historical overview since bezoars stones were thought to have medicinal properties. This magic conception was introduced in South America by Spanish conquerors. In Chile, bezoars are commonly found in a camelid named guanaco (Lama guanicoe)...

Therapeutic access to the biliary system is generally limited to endoscopic or percutaneous approaches. A variety of percutaneous transhepatic biliary interventions are applicable for the diagnosis and treatment of biliary system pathologies, the majority of which may be performed in conjunction with one another. The backbone of nearly all of these interventions is percutaneous transhepatic cholangiography for opacification of the biliary tree, after which any number of therapeutic or diagnostic modalities may be pursued...

BACKGROUND: Abdominal aortic aneurysm (AAA) wall inflammation and mechanical structural stress may influence AAA expansion and lead to rupture. We hypothesized a positive correlation between structural stress and fluorine-18-labeled 2-deoxy-2-fluoro-d-glucose ((18)F-FDG) positron emission tomography-defined inflammation. We also explored the influence of computed tomography-derived aneurysm morphology and composition, including intraluminal thrombus, on both variables. METHODS AND RESULTS: Twenty-one patients (19 males) with AAAs below surgical threshold (AAA size was 4...

Direct numerical simulations were performed on four patient-specific abdominal aortic aneurysm (AAA) geometries and the resulting pulsatile blood flow dynamics were compared to aneurysm shape and correlated with intraluminal thrombus (ILT) deposition. For three of the cases, turbulent vortex structures impinged/sheared along the anterior wall and along the posterior wall a zone of recirculating blood formed. Within the impingement region the AAA wall was devoid of ILT and remote to this region there was an accumulation of ILT...

During Salmonella Typhimurium infection, intestinal CX3CR1(+) cells can either extend transepithelial cellular processes to sample luminal bacteria or, very early after infection, migrate into the intestinal lumen to capture bacteria. However, until now, the biological relevance of the intraluminal migration of CX3CR1(+) cells remained to be determined. We addressed this by using a combination of mouse strains differing in their ability to carry out CX3CR1-mediated sampling and intraluminal migration. We observed that the number of S...

Cystadenoma is a rare benign salivary gland epithelial tumor that is characterized by intraluminal papillary projection. Majority of the tumors are located in minor salivary glands and usually occur in palatal and buccal mucosa, but rarely found in retromolar area. Clinically it is difficult to differentiate it from other minor salivary gland tumors, and diagnosis is chiefly based on characteristic clinical features and immunohistochemistry. We present a case of Cystadenoma arising from the minor salivary gland in retromolar area of a 44 year old female patient with a special emphasis on the immunohistochemistry to rule out the metastatic follicular carcinoma of thyroid...

EXT-induced arteriolar adaptations in skeletal muscle are heterogeneous because of spatial variations in muscle fiber type composition and fiber recruitment patterns during exercise. The purpose of this report is to summarize a series of experiments conducted to test the hypothesis that changes in vascular gene expression are signaled by alterations in shear stress resulting from increases in blood flow, muscle fiber type composition and fiber recruitment patterns. We also report results from a follow-up study of Ankrd23, one gene whose expression was changed by EXT...

OBJECTIVES: The aim of this study was to identify histological features that correlate with terms commonly used to describe optical coherence tomographic (OCT) and optical frequency-domain imaging (OFDI) images of stented vessels, by means of a histopathological validation study using stented human coronary arteries. BACKGROUND: OCT imaging and OFDI are used to evaluate vascular responses to stent implantation. Descriptive terms such as "peristrut low attenuation" and "heterogeneous" have been used to describe neointimal characteristics that may have clinical relevance...

BACKGROUND: Positive end-expiratory pressure (PEEP) has beneficial pulmonary effects but may worsen the hemodynamic repercussions induced by pneumoperitoneum (PNP) in patients undergoing liver laparoscopic liver resection. However, by the increase of intraluminal vena cava (VC) pressures, PEEP may prevent PNP-induced VC collapse. The aim of this original article was to test the validity of this hypothesis. METHODS: After IRB approval and written inform consents, 20 patients were prospectively evaluated...

REVIEW
Nathan J Pavlos, Peter A Friedman
Emerging findings disclose unexpected components of G protein-coupled receptor (GPCR) signaling and cell biology. Select GPCRs exhibit classical signaling, that is restricted to cell membranes, as well as newly described persistent signaling that depends on internalization of the GPCR bound to β-arrestins. Termination of non-canonical endosomal signaling requires intraluminal acidification and sophisticated protein trafficking machineries. Recent studies reveal the structural determinants of the trafficking chaperones...

Elastin and collagen fibers play important roles in the mechanical properties of aortic media. Because knowledge of local fiber structures is required for detailed analysis of blood vessel wall mechanics, we investigated 3D microstructures of elastin and collagen fibers in thoracic aortas and monitored changes during pressurization. Using multiphoton microscopy, autofluorescence images from elastin and second harmonic generation signals from collagen were acquired in media from rabbit thoracic aortas that were stretched biaxially to restore physiological dimensions...

The Crosser catheter is a unique device that facilitates antegrade intraluminal recanalization by high-frequency vibration energy and cavitation. We used this device not only as a chronic total occlusion (CTO) crossing device, but also as a flossing device in stenotic lesions and we also evaluated the efficacy of this device when used with both the "Crosser preceding" and the "Guidewire preceding" in CTOs. Complications related to this device were investigated, too. We retrospectively analyzed a total of 90 consecutive patients with peripheral artery disease in the femoropopliteal artery and below-the-knee artery (BTA)...

A 46-year-old Chinese woman with a history of cholecystectomy and appendicectomy presented to the emergency department with symptoms of intestinal obstruction. Physical examination revealed central abdominal tenderness but no clinical features of peritonism. Plain radiography of the abdomen revealed a grossly distended large bowel loop with the long axis extending from the right lower abdomen toward the epigastrium, and an intraluminal air-fluid level. These findings were suspicious for an acute caecal volvulus, which was confirmed on subsequent contrast-enhanced computed tomography (CT) of the abdomen and pelvis...

In drug development, the stomach is often considered to be a simple, one-compartmental organ, a waiting room for transfer of an orally administered dosage form to the duodenum. However, factors such as gastric acidity and hydrodynamics in the gastric environment may influence drug disposition. Although a link between gastrointestinal drug behaviour and gastric motility has often been hypothesized, they have not been simultaneously investigated in humans yet. In this proof-of-concept study, the combination of a well-established intraluminal sampling technique with high-resolution manometric measurements in the gastrointestinal tract was evaluated...
