Non invade ventilation

INTRODUCTION AND IMPORTANCE: Intratracheal tumors account for approximately 0.2 % of respiratory tumors, including primary and secondary tumors. Secondary tumors of the upper trachea are most commonly derived from advanced thyroid cancer. Surgical resection is currently the general curative modality for thyroid cancer with tracheal invasion. Patients with tracheal tumors invading and protruding into the lumen may have reduced oxygen reserve capacity, leading to a shorter safe window for general anesthesia induction...

BACKGROUND: Since the first attempts for ventilation, there have been significant changes in terms of the size of devices, ventilation techniques, and technology. In time, invasive methods and huge devices were replaced by non-invasive methods and small and portable devices. Increased use of non-invasive methods was followed by enrichment of literature on the topic. This study aimed to determine the evolution of non-invasive ventilation (NIV) literature and predict future trends. MATERIALS AND METHODS: We used the Web of Science database for search...

Novel approaches to treat carbapenem-resistant Acinetobacter baumannii (CRAB) infections are urgently needed and anti-virulence drugs represent promising alternatives, but our knowledge on potential targets is scarce. We searched for potential A. baumannii virulence factors by whole-genome sequencing-based comparisons of CRAB clinical isolates causing bloodstream infections secondary to ventilator-associated pneumonia from demographics and clinically homogeneous patients, who received optimal treatment but with different clinical outcomes...

BACKGROUND: Primary cardiac neoplasms are extremely rare, with an autopsy incidence of 0.0001-0.003%. Primary cardiac sarcoma is usually derived from the right atrium and it manifests as chest pain, arrhythmia, hemoptysis, dyspnea, and fatigue. The most common target organ for metastasis of primary angiosarcoma is the lungs, but the radiological-pathological correlation has been rarely reported. CASE PRESENTATION: A 38-year-old healthy Japanese man was admitted to our hospital with persistent hemoptysis, exaggerated dyspnea, and two episodes of loss of consciousness in the past 3 months...

We report the case of isolation of Bordetella trematum from the respiratory tract of a patient with lung carcinoma. This gram-negative, opportunistic rod was firstly described in 1996. To date, only several strains of Bordetella trematum have been isolated and reported, mostly from skin and soft tissue infections. The patient was admitted to the ICU of the Pulmonary Department in incipient septic shock with respiratory failure. Intravenous fluid resuscitation and non-invasive ventilation were administered immediately...

BACKGROUND: Non-invasive ventilation is used with a mechanical ventilator and an interface that is interposed between the patient and the ventilator without invading the airway. It is an alternative to the artificial airway in situations of acute respiratory insufficiency. OBJECTIVE: Determine if the selection of an appropriate interface to the contour of the patient's face and the pathology involves the triumph or failure of the procedure, deeming it is a dependent variable in the success of the NIV...

OBJECTIVE: To investigate the prevalence and risk factors of upper gastrointestinal bleeding (UGIB) in patients with severe acute pancreatitis (SAP). METHODS: Altogether 101 patients were admitted to the Department of Gastroenterology, Changhai Hospital, Second Medical Military Hospital from July 2006 to June 2010 due to SAP. Their prevalence and risk factors of UGIB were retrospectively analyzed. RESULTS: In total, 18 (17.8%) patients developed UGIB and 13 received endoscopic examination, which yielded six cases of acute gastric mucosal lesions (AGML), five of peptic ulcers (PU) and two of pancreatic necrotic tissue invading the duodenal bulb and presenting as multilesion, honeycomb-like ulcer...

Non-invasive mechanical ventilation is a technique that has ceased to be exclusively used in intensive medicine services to form part of the armamentarium of emergency and critical services, assuming an adaptation to this procedure by the nursing staff whose participation is crucial to achieve the triumph of technique. Composed basically of a mechanical ventilator and a mask (interface) which is interposed between the patient and the fan without invading the airway, requires the collaboration of the patient unlike conventional mechanical ventilation and, initially, a longer time of dedication of the nurse...

Uniquely among extant vertebrates, birds possess complex respiratory systems characterised by the combination of small, rigid lungs, extensive pulmonary air sacs that possess diverticula that invade (pneumatise) the postcranial skeleton, unidirectional ventilation of the lungs, and efficient crosscurrent gas exchange. Crocodilians, the only other living archosaurs, also possess unidirectional lung ventilation, but lack true air sacs and postcranial skeletal pneumaticity (PSP). PSP can be used to infer the presence of avian-like pulmonary air sacs in several extinct archosaur clades (non-avian theropod dinosaurs, sauropod dinosaurs and pterosaurs)...

To determine whether there are differences in risk factors and outcomes among patients with E. coli bacteremia caused by strains that produce CTX-M or non-CTX-M extended-spectrum beta-lactamases. From 1 July 2005 to 30 June 2007, patients with positive blood culture of extended-spectrum β-lactamases (ESBL)-producing E. coli were reviewed. Sixty patients with ESBL-producing E. coli bacteremia were identified. These included 41 (68.3%) isolates with CTX-M β-lactamases. CTX-M-14 accounted for 31 (75.6%) and CTX-M-3 for 9 (22...

Sepsis is physiologically viewed as a proinflammatory and procoagulant response to invading pathogens. There are three recognized stages in the inflammatory response with progressively increased risk of end-organ failure and death: sepsis, severe sepsis, and septic shock. Patients with cirrhosis are prone to develop sepsis, sepsis-induced organ failure, and death. There is evidence that in cirrhosis, sepsis is accompanied by a markedly imbalanced cytokine response ("cytokine storm"), which converts responses that are normally beneficial for fighting infections into excessive, damaging inflammation...

BACKGROUND: We present our perioperative management of operable nonsmall-cell lung cancer invading the tracheobronchial bifurcation and the results obtained. METHODS: Fifty consecutive patients undergoing carinal surgery with radical lymphadenectomy over a 5-year period were studied. RESULTS: Eighteen patients (36%) were N2 and had chemoradiation (48 +/- 6 Gy) preoperatively. Surgery included 34 carinal pneumonectomies (24 right, 10 left), 11 carinal lobectomies (n = 6) or bilobectomies (n = 5), and 5 carinal resections, with (n = 3) and without (n = 2) reconstructions...

Determining the appropriate surgery-based treatment for complicated anterior mediastinal malignancies (CAMM), especially those invading the superior vena cava (SVC) and its branches, remains a challenge for general thoracic surgeons. In this report, we summarize our experience and lessons regarding this issue in order to discuss a reasonable strategy for diagnosis and treatment of CAMM. Between January 2001 and April 2003, 15 patients with CAMM invading the SVC and/or its branches with or without invasion of other neighboring organs were surgically treated in our institution by a single surgeon team...

BACKGROUND: Resection of T4 non-small cell lung cancer (NSCLC) on cardiopulmonary bypass (CPB) has rarely been reported in the literature. Hence, we have reviewed our experience in the role of CPB for the surgical treatment of locally advanced NSCLC. METHODS: All patients undergoing lung resection for bronchogenic carcinoma on CPB in our institution between January 1998 and June 2004 were reviewed. RESULTS: Seven patients underwent lung resections on CPB for bronchogenic carcinoma during the study period...

OBJECTIVE: To propose a new hypothesis that attempts to explain the pathogenesis of petrous apex cholesterol granuloma (PA CG). CLASSIC OBSTRUCTION-VACUUM HYPOTHESIS: PA CGs form when mucosal swelling blocks the circuitous pneumatic pathways to the apical air cells. Trapped gas resorption results in a vacuum that triggers bleeding, and CG forms through anaerobic breakdown of blood products. PROBLEMS WITH THE CLASSIC (OBSTRUCTION-VACUUM) HYPOTHESIS: Impaired ventilation of mucosa-lined pneumatic tracts in the middle ear, mastoid, paranasal sinuses, and lung are very common, but CG is rare...

Inflammation represents the consequence of capillary dilation with accumulation of fluid and transmigration of leukocytes into the surrounding tissue. Leukocytes play a major role in the defense system of the body against invading microorganisms. This defense system has a non-specific branch consisting of granulocytes and macrophages and a specific branch of lymphocytes. Granulocytes release cytotoxic compounds from their intracellular granules into their local environment when encountering microorganisms. This random destruction happens rapidly, but it may also harm healthy tissue of the body...

BACKGROUND: Neutrophils are of great importance for the host's defense against invading organisms. Granulocyte colony-stimulating factor (G-CSF) has been used to augment both the neutrophil number and function, and its prophylactic administration has proved beneficial in animal models of sepsis. However, pretreatment with G-CSF is not practical under clinical conditions. We therefore investigated the effect of recombinant human (rh)G-CSF, administered only after infection, on the survival rate as well as the hemodynamic and cytokine response of the animals...
