Filter by:The Thoracic ultrasound is a safer and sensitive technique than conventional radiography because it detects less than 1 cm pneumonic consolidations and minimal pleural effusions. The main objective is to evaluate the efficacy of thoracic ultrasound performed by unskilled personnel in the emergency service prdiatricas to diagnose pneumonia in children.
This study will investigate the safety and efficacy of the administration of inhaled GM-CSF to patients with respiratory virus-associated pneumonia.
Ventilator associated pneumonia (VAP) is common problem among ICU patients and major source of infection among patients receiving mechanical ventilation. Patients on mechanical ventilation accumulate secretion leading to aspiration of infected secretions. Using new generation endotracheal tube (Hi-Lo tube) can reduce the incidence of VAP.
This study will be a double-blind, randomized, multicenter trial to assess the safety and efficacy of a single 1500 mg IV dose of dalbavancin plus a single 500 mg IV dose of azithromycin in comparison to an approved antibiotic regimen of linezolid 600 mg every 12 hours for 10-14 days plus a single 500 mg IV dose of azithromycin for the treatment of Community Acquired Bacterial Pneumonia.
To demonstrate the safety and efficacy of adjunctive therapy with the Amikacin Fosfomycin Inhalation System (AFIS) versus aerosolized placebo in mechanically ventilated patients with Gram-negative and / or Gram-positive bacterial colonization.
The purpose of the study is to create a clinical pneumonia tool that can be used to predict the cause of community-acquired pneumonia, which is a lung infection that began outside of the hospital in critically ill children therefore limiting unnecessary antibiotic use. The investigators will enroll critically ill children admitted with acute respiratory failure and suspected pneumonia. Each patient will receive a clinical pneumonia score blinded from culture and respiratory viral panel results. All care after samples obtained will be at the discretion of the PICU team. The investigators believe that our clinical pneumonia scale with procalcitonin will accurately designate viral from bacterial etiologies.
Background and rationale: Antimicrobial resistance is a global public health threat. An increasing number of Gram-negative bacteria isolates worldwide are resistant to virtually all antibiotics including carbapenems. Although polymyxins are the current gold standard antibiotic for treatment of severe extensively drug-resistant Gram-negative bacteria (XDR-GNB - defined in Appendix I) infections, resistance development on therapy and treatment failures are common. Combination antibiotics therapy have better in vitro efficacy, but have not been formally tested in a prospective trial. We will conduct a Phase IIB, prospective, open-label, randomized-controlled trial in 4 major Singaporean hospitals, with balanced treatment assignments achieved by permuted block randomization, stratified by hospital. There will be 75 subjects per arm, with the subjects in the comparator arm receiving standard-dose polymyxin B while the intervention arm will receive a second antibiotic, doripenem, with polymyxin B against the bacterial isolate in question. Subjects with ventilator-associated pneumonia (VAP) will additionally receive nebulized colistin. The primary outcome is 30-day mortality while secondary outcomes include microbiological clearance, time to defervescence, and toxicity of therapy, presence of secondary infections due to new multi-drug resistant bacteria and length of ICU stay. Plasma drug levels will be measured by liquid chromatography-mass spectrometry. Hypothesis: The underlying primary hypothesis is that combination antibiotic therapy (IV polymyxin B + IV doripenem) is superior to mono-antibiotics therapy (IV polymyxin B) in reducing 30-day mortality from XDR-GNB infections.
Historically, ultrasound has been unable to provide interpretable data from the lung parenchyma, mainly because of the high total ultrasound energy attenuation and scattering by the air in the lungs. Recently it has been shown that clear reproducible Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package (transthoracic parametric Doppler, TPD, EchoSense Ltd., Haifa, Israel). These lung Doppler signals (LDS) are in full synchrony with the cardiac cycle and can be obtained from the lungs, including areas remote from the heart and main pulmonary vessels. The LDS waves typically have peak velocities of up to 30 cm/s and are of relatively high power, making it possible to detect them despite the aforementioned attenuation by the air in the lungs. The LDS are thought to represent the radial wall movement of small pulmonary blood vessels, caused by pressure pulse waves of cardiac origin which propagate throughout the lung vasculature. The LDS may contain information of significant diagnostic and physiological value regarding the pulmonary parenchyma and vasculature, as well as the cardio-vascular system in general. Preliminary data from ongoing studies employing the TPD in chronic diseases such as CHF, COPD and pulmonary hypertension, show promise regarding the diagnostic potential of the lung Doppler signals (unpublished data). However, lung Doppler signals in acute disease states were not investigated so far. It is reasonable to speculate that the pathological processes underlying acute cardiovascular and pulmonary diseases will affect the LDS. Therefore, the TPD may have diagnostic potential in these conditions. For example, during acute pulmonary embolism a portion of the pulmonary vascular system is occluded; therefore it's reasonable to assume that the LDS will disappear in the affected area, enabling to confirm the diagnosis without using ionizing radiation (as in CT or lung scan). Another example is COPD exacerbation, during which there is usually air trapping in the lungs; thus, the LDS may be attenuated by the increase of air volume in the lungs.
This PMS study aims to collect safety and reactogenicity data of Synflorix™ in healthy infants and children of the local population as per the licensing requirement of the Sri Lankan regulatory authority.
Intravenous Azythromycin therapy is considerably more expensive than oral therapy. The investigators believe that intravenous therapy is prolonged more that necessary and that oral therapy can be used much earlier in the course of the disease. The investigators plan to check if that statement is true and intervene in order to shorten the intravenous therapy.
