- ItemEndoscopic lung volume reduction in severe emphysema(Health & Medical Publishing Group, 2015) Koegelenberg, Coenraad Frederik N.; Theron, Johan; Bruwer, J. W.; Allwood, Brian W.; Vorster, Morne J.; Von Groote-Bidlingmaier, Florian; Dheda, KeertanENGLISH ABSTRACT: Therapeutic options in severe emphysema are limited. Endoscopic lung volume reduction (ELVR) refers to bronchoscopically inducing volume loss to improve pulmonary mechanics and compliance, thereby reducing the work of breathing. Globally, this technique is increasingly used as treatment for advanced emphysema with the aim of obtaining similar functional advantages to surgical lung volume reduction, while reducing risks and costs. There is a growing body of evidence that certain well-defined subgroups of patients with advanced emphysema benefit from ELVR, provided that a systematic approach is followed and selection criteria are met. In addition to endobronchial valves, ELVR using endobronchial coils is now available in South Africa. The high cost of these interventions underscores the need for careful patient selection to best identify those likely to benefit from such procedures.
- ItemA practical approach to diagnosing pleural effusion in Southern Africa(Health & Medical Publishing Group, 2013) Bruwer, J. W.; Batubara, E.; Koegelenberg, C. F. N.Excessive fluid accumulating within the pleural space is a common medical affliction and invariably indicates disease. [1,2] Under physiological conditions fluid enters and exits the pleural space at the same rate.[3] The rate of production is determined by Starling’s forces, i.e. hydrostatic pressure, osmotic pressure and membrane permeability, whereas the exit rate is determined by clearance through lymphatic drainage.[3] Alterations in any of these forces can lead to the formation of a pleural effusion.
