Hospitalised Patients

Objective: A pressure ulcer (PU) is an area of tissue trauma caused by continuous and prolonged pressure, often associated with hospitalised patients immobilised due to neurological problems, negatively affecting their quality of life, and burdening the public budget. The aim of this study was to report the follow-up, for 45 weeks, of three patients with neurological lesions due to trauma who subsequently developed PUs, and who were treated with a combination of photodynamic therapy (PDT), low level laser therapy (LLLT) and cellulose membrane (CM). Method: PDT was mediated by the photosensitiser curcumin on a 1.5% emulsion base. Blue LED light at 450 nm was delivered continuously for 12 minutes at an irradiance of 30mW/cm2 and total energy delivered to the tissue was 22J/cm2. LLLT was performed with 660 nm laser, punctuated and continuous, twice a week with parameters: spot size 0.04cm2, power of 40mW, 10 seconds per point, fluence of 10J/cm2 and irradiance of 1000mW/cm2. Results: All PUs had a significant reduction (range: 95.2–100%) of their area after 45 weeks of follow-up and two PUs had complete healing at 20 weeks and 30 weeks. All of the PUs showed a reduction in contamination with the PDT treatments in different proportions. Conclusion: From the results obtained, we conclude that the combination of PDT, LLLT and CM is a promising treatment for PU healing.

AbstractThe objective of this study was to investigate the effect of power on low-level lasers used in photodynamic therapy (PDT) to treat chronic plaque psoriasis in a group of Sudanese patients.Twenty-four patients with chronic plaque psoriasis were randomly selected to enter this study from a total of 100 patients who attended the Khartoum Dermatology Teaching Hospital between 2010 and 2011. The lasers used for PDT were three continuous wave diode lasers in the red portion of the electromagnetic spectrum (671–675 nm) with output powers of 16, 50 and 100 mW to activate the chemical photosensitizer (LevulanThis study showed that 62% of the patients treated with 100 mW achieved complete clearance compared with 25% for those treated with 50 mW and 0% for those treated with 16 mW.The results showed that increasing the power of low-level laser in PDT increased the clearance of plaque psoriasis. PDT can be used as an alternative method for treatment of psoriasis.

Suggested here is a neural net algorithm for the n-queens problem. The net is basically a Hopfield net but with one major difference: every unit is allowed to inhibit itself. This distinctive characteristic enables the net to escape efficiently from all local minima. The net’s dynamics then can be described as a travel in paths of low-level energy spaces until it finds a solution (global minimum). The paper explains why standard Hopfield nets have failed to solve the queens problem and proofs that the self-inhibiting net (NQ2 algorithm in the text) never stabilizes in local minima and relaxes when it falls into a global minimum are provided. The experimental results supported by theoretical explanation indicate that the net never continually oscillates but relaxes into a solution in polynomial time. In addition, it appears that the net solves the queens problem regardless of the dimension n or the initialized values. The net uses only few parameters to fix the weights; all globally determined as a function of n.
