influence of a specialised leg ulcer Service and venous surgery on the outcome of venous leg ulcers
European Journal of Vascular and Endovascular Surgery, 1998Co-Authors: A S K Ghauri, I Nyamekye, Anthony J Grabs, J R Farndon, M R Whyman, K R PoskittAbstract:Objectives: To assess the influence of a vascular-led community Service on the outcome of chronic leg ulcers. Design: Before and after study. Method: Healing and recurrence were compared between ulcerated limbs (n=149) from a random sample of 200 patients treated in the community and consecutive limbs (n=200) from 180 patients treated in specialised clinics. In these clinics, vascular disease was Routinely identified with venous duplex and ankle-brachial pressure index. Surgery was offered if superficial vein reflux alone was detected. Compression bandaging was applied to limbs with ABPI >0.85. Healed limbs were treated with compression hosiery. Results: After the clinics were introduced, the 12 and 24-week healing rates increased from 12 and 29 per cent to 53 and 68 per cent respectively (p Conclusion: Outcome of leg ulcers is improved in a vascular-led community Service. Routine surgical correction, in cases of reflux limited to the superficial system, may further reduce the chance of recurrence.

testing interrupts having a Service priority order by applying different interrupt priority levels
2001Co-Authors: Harry AthanassiadisAbstract:A test of interrupts in a microprocessor system having a number of interrupt sources which are associated with a memory and assigned a default priority level and a position in a Service order. In operation requests for Service from the interrupt sources will be processed by calling the interrupt Service Routine of the interrupt request having the highest priority level or in the event that interrupt requests are at the same priority level are received the interrupt requests will be Serviced from first in the Service order to last in the Service order. The testing mechanism comprises applying an array of priority levels (priority window) to some of the interrupt request lines and enabling all other interrupt requests at their default priority level simultaneously. A value from a global counter is then applied to the memory associated with the interrupt source which is to be Serviced. This global counter is then incremented by one and the array of priority values is shifted along the Service order from last in the Service order to first for successive tests until the test is complete (figure 2b). The values stored in the memories associated with each interrupt source are then compared to a pre-arranged sequence of expected values to determine if an error has occurred in the microprocessor interrupts.

testing interrupts having a Service priority order by applying combinations of interrupt priority levels
2001Co-Authors: Harry AthanassiadisAbstract:A test of interrupts in a microprocessor system having a number of interrupt sources which are associated with a memory and assigned a default priority level and a position in a Service order. In operation requests for Service from the interrupt sources will be processed by calling the interrupt Service Routine of the interrupt request having the highest priority level or in the event that interrupt requests are at the same priority level are received the interrupt requests will be Serviced from first in the Service order to last in the Service order. The testing mechanism comprises applying an array of priority levels (priority window, figure 1) except the interrupt having the highest priority to some of the interrupt request lines and enabling all other interrupt requests at their default priority level simultaneously. A value from a global counter is then applied to the memory associated with the interrupt source which is to be Serviced. This global counter is then incremented by one and the test is repeated enabling all interrupts simultaneously including the interrupt having the highest priority and the value in the global counter is again applied to the memory of the interrupt to be Serviced. Next the array of priority values is shifted along the Service order from last in the Service order to first according to a sequence for successive tests until all tests have been completed (figure 2b). The values stored in the memories associated with each interrupt source are then compared to a pre-arranged sequence of expected values to determine if an error has occurred in the microprocessor interrupts.
