Nuclear medicine dynamic investigations of diffuse chronic liver diseases and portal hypertension.
Authors: Dragoteanu M, Cotul SO, Tamas S, Piglesan C Abstract Radio-isotopic techniques may be useful in diagnosis and staging of chronic diffuse liver diseases. Liver angioscintigraphy (LAS) and per-rectal portal scintigraphy (PRPS) are at well discriminating portal hypertension (PHT), very early cirrhosis hemodynamic failure and compensatory arterialisation of liver perfusion. Supplied information is related to PHT, liver morphology and mesenchimal activity in liver, spleen and bone marrow. Correlation of LAS and PRPS may diagnose installing of PHT earlier than any actual morphologic imagistic method. Our experie...

Respiratory system: applied pharmacology
Publication date: November 2014 Source:Anaesthesia & Intensive Care Medicine, Volume 15, Issue 11 Author(s): Richard L. Dodwell , Jonathan B. Kendall Manipulation of respiratory physiology by pharmacological intervention is a significant role of the anaesthetist and intensivist. Successful use of these various agents requires a thorough understanding of their mechanisms of actions, potential side-effects and limitations. These interventions involve changes in airway calibre, secretions and sensitivity of the airway to noxious stimuli. Other agents act to inhibit the depressant effect that sedatives may have on th...

Use of a novel hemoadsorption device for cytokine removal as adjuvant therapy in a patient with septic shock with multi-organ dysfunction: A case study
Reshma Basu, Sunjay Pathak, Jyoti Goyal, Rajeev Chaudhry, Rati B Goel, Anil BarwalIndian Journal of Critical Care Medicine 2014 18(12):822-824CytoSorb ® (CytoSorbents Corporation, USA) is a novel sorbent hemoadsorption device for cytokine removal. The aim of this study was to examine the clinical use of CytoSorb ® in the management of patient with septic shock. We used this device as an adjuvant to stabilize a young patient with multi-organ failure and severe sepsis with septic shock. A 36-year-old female patient was hospitalized with the complaints of malaise, general body ache, and breathing diffi...

Measurement of respiratory function: an update on gas exchange
Publication date: Available online 15 January 2015 Source:Anaesthesia & Intensive Care Medicine Author(s): Salahuddin Mahmood Qureshi Gas exchange is the main function of the lungs. Oxygen and carbon dioxide diffuse along their partial pressure gradient across the alveolar-capillary membrane. Lungs have a large reserve for gas exchange. Alveolar ventilation and pulmonary circulation are closely matched to provide efficient gas exchange in the lungs. Hypoxaemia often results from mismatch in ventilation–perfusion. Gas exchange can be impaired in various disease states. Measurement of the diffusing capacity for c...

Assessment of microcirculation by contrast-enhanced ultrasound: a new approach in vascular medicine.
Abstract Contrast-enhanced ultrasound (CEUS) has emerged as a valuable imaging modality that complements and enhances standard vascular ultrasound imaging. Ultrasound contrast agents are gas-filled microbubbles that are injected intravenously and serve as intravascular tracers. Based on the properties to enhance and to quantify the macro- and microcirculation down to the capillary perfusion level in different vascular territories and organs, CEUS imaging has the potential to improve the diagnostic performance in the detection and characterisation of various vascular disorders reviewed in this article. In carotid a...

Ischemic Colitis
Publication date: Available online 17 January 2015 Source:Hospital Medicine Clinics Author(s): Kathy Navid , Umesh Gidwani , Juan Pena , Andrew DunnTeaser Ischemic colitis (IC) is the most common form of intestinal ischemia and results from inadequate colonic perfusion from low flow states, arterial thrombosis, embolism, or ligation and can also occur postoperatively from cardiac or gastrointestinal surgery. Most IC is idiopathic or caused by shock associated with sepsis. Treatment is generally supportive and most patients recover with conservative measures; however, approximately 20% will require surgical intervention, ...

Dynamic Contrast-Enhanced Ultrasound for Quantification of Tissue Perfusion
This article reviews and discusses the published literature on the clinical use of dynamic contrast-enhanced US. This review finds that dynamic contrast-enhanced US imaging is the most sensitive cross-sectional real-time method for measuring the perfusion of parenchymatous organs noninvasively. It can measure parenchymal perfusion and therefore can differentiate between benign and malignant tumors. The most important routine clinical role of dynamic contrast-enhanced US is the prediction of tumor responses to chemotherapy within a very short time, shorter than using Response Evaluation Criteria in Solid Tumors criteria. Ot...

Utility of left lateral supine position for myocardial perfusion single-photon emission computed tomography compared with other methods of correcting inferior wall attenuation
Conclusion: Visual and quantitative evaluations of the variation in inferior wall activity lead us to suggest that SPECT imaging with Tc-99m MIBI be performed in the left lateral position to allow better visualization of the inferior and septal walls in those departments not able to utilize computed tomographic attenuation correction.
