Papase as a treatment option for the overgranulating wound

Mustafah NM, Chung TY

J Wound Care, 2014 Feb;23(2 Suppl):S10-2.
PMID: 24526167

Overgranulation (also commonly known as hypergranulation) is a common problem in chronic wound management. We describe a case involving a 57-year-old lady with a chronic diabetic foot ulcer, complicated with overgranulation for the past year. She was administered with various treatments, including hydrocortisone 1% cream and hydrofiber, which proved ineffective and further delayed the healing process of her ulcer. We then decided to use crushed Papase tablets applied to her ulcer after a normal saline dressing and prior to an application of secondary dressing. The patient was instructed clearly on the dressing technique to be performed daily at home and was monitored weekly in a foot care clinic. The overgranulation resolved within 5 weeks and the patient continues recieving care to promote epithelialisation.

Maggot debridement therapy with Lucilia cuprina: a comparison with conventional debridement in diabetic foot ulcers

Paul AG, Ahmad NW, Lee HL, Ariff AM, Saranum M, Naicker AS, et al.

Int Wound J, 2009 Feb;6(1):39-46.
PMID: 19291114 DOI: 10.1111/j.1742-481X.2008.00564.x

This is prospective case-control study of more than 18 months performed to assess the effectiveness of maggot debridement therapy (MDT) with the sterile larvae of Lucilia cuprina (a tropical blowfly maggot) for the treatment of diabetic foot ulcers. Literature thus far has only reported results with the temperate maggot, Lucilia sericata. This study documents outcome in diabetic foot wounds treated with maggot debridement versus those treated by conventional debridement alone. In this series of 29 patients treated with MDT, 14 wounds were healed, 11 were unhealed and 4 were classified under others. The control group treated by conventional debridement had 30 patients of which 18 wounds were healed, 11 unhealed and 1 classified under others. There was no significant difference in outcome between the two groups. The conclusion that can be made from this study is that MDT with L. cuprina is as effective as conventional debridement in the treatment of diabetic foot ulcers. It would be a feasible alternative to those at high risk for surgery or for those who refuse surgery.

Increasing productivity with smartphone digital imagery wound measurements and analysis

Nair HKR

J Wound Care, 2018 Sep 01;27(Sup9a):S12-S19.
PMID: 30207849 DOI: 10.12968/jowc.2018.27.Sup9a.S12

OBJECTIVE: The primary aim was to determine the productivity increase using digital imagery for better documentation and analysis. A case series was done in a specialised care centre with patients managed with advanced dressings and using state-of-the-art smartphone technology for documentation to save costs and time.
METHOD: Wounds were cleansed and debrided before using the application to photograph, document, measure and analyse the wounds. The smartphone app was oriented parallel to the plane of the wound, where possible, to obtain accurate measurements. A longitudinal study report was generated for each wound and showed the progress of the wound healing until the wound was closed.
RESULTS: A sample size of 60 patients consisting of wounds from different locations, and a total of 203 measurements and analyses were conducted over a period of seven months. The wound monitoring app proved to be effective for wound monitoring and required less than two hours' training. A report summary of wounds recorded could also be generated automatically through the dashboard. All 60 patients' cases were automatically recorded, measured and presented into reports for use in clinical analysis. There was a significant time savings (27 hours per day for a specialised care centre with 10 nurses) increase over manual wound documentation and measuring methods.
CONCLUSION: The app provided a non-contact, easy to use, reliable and accurate smart wound management solution for clinicians and physicians to track wound healing in patients. The app could also be used by patients and caregivers for home monitoring of their wounds.

Silver nanoparticles: Advanced and promising technology in diabetic wound therapy

Choudhury H, Pandey M, Lim YQ, Low CY, Lee CT, Marilyn TCL, et al.

Mater Sci Eng C Mater Biol Appl, 2020 Jul;112:110925.

Wounds associated with diabetes mellitus are the most severe co-morbidities, which could be progressed to cause cell necrosis leading to amputation. Statistics on the recent status of the diabetic wounds revealed that the disease affects 15% of diabetic patients, where 20% of them undergo amputation of their limb. Conventional therapies are found to be ineffective due to changes in the molecular architecture of the injured area, urging novel deliveries for effective treatment. Therefore, recent researches are on the development of new and effective wound care materials. Literature is evident in providing potential tools in topical drug delivery for wound healing under the umbrella of nanotechnology, where nano-scaffolds and nanofibers have shown promising results. The nano-sized particles are also known to promote healing of wounds by facilitating proper movement through the healing phases. To date, focuses have been made on the efficacy of silver nanoparticles (AgNPs) in treating the diabetic wound, where these nanoparticles are known to exploit potential biological properties in producing anti-inflammatory and antibacterial activities. AgNPs are also known to activate cellular mechanisms towards the healing of chronic wounds; however, associated toxicities of AgNPs are of great concern. This review is an attempt to illustrate the use of AgNPs in wound healing to facilitate this delivery system in bringing into clinical applications for a superior dressing and treatment over wounds and ulcers in diabetes patients.

Risk factor analysis on the healing time and infection rate of diabetic foot ulcers in a referral wound care clinic

Kee KK, Nair HKR, Yuen NP

J Wound Care, 2019 Jan 01;28(Sup1):S4-S13.
PMID: 30724120 DOI: 10.12968/jowc.2019.28.Sup1.S4

OBJECTIVE:: Objectives. To determine the prevalence and risk factors for diabetic foot infection (DFI), and to identify factors associated with delayed wound healing of diabetic foot ulcer (DFU).
METHOD:: The retrospective study was performed in a referral wound care clinic in Hospital Kuala Lumpur. Data was collected from January 2014 to October 2016 on DFU patients who attended this clinic.
RESULTS:: Of the 340 patients (216 male and 124 female) DFU patients who attended the clinic (mean age: 58.1±10.8 years old), 41.5% presented with infection with a mean cross-sectional ulcer area of 21.5±33.2cm2. Binary logistic regression analysis revealed that patients of Chinese ethnicity (OR: 3.39; 95%CI 1.49 to 7.70), with fasting blood glucose ≥7mmol/l (OR: 3.41; 95%CI 1.57 to 7.39), ulcer size ≥10cm2 (OR: 2.90; 95%CI 1.45 to 5.82) and blood pressure ≥140/90mmHg (OR: 2.52; 95%CI 1.54 to 4.14) were more likely to develop DFI. The median healing time for patients with DFUs was three months. There were six variables identified as significantly associated with prolonged healing time of DFU, namely presence of infection (p<0.001), poor glycaemic control with fasting blood glucose ≥7mmol/l (p<0.001), high blood pressure ≥140/90mmHg (p<0.001), large DFU size ≥2cm2 (p<0.001), history of amputation (p<0.005) and plantar location of the DFU (p<0.05).
CONCLUSION:: Large DFU size, poor glycaemic and blood pressure control are common risk factors for both DFU and DFI. Unexpected high prevalence and ethnicity risk factor for DFI urge more comprehensive primary and secondary preventative strategies to reduce its incidence.

PMID: 18301834

INTRODUCTION: This study was designed to evaluate the histopathological features of skin microvasculature in patients with a diabetic foot, specifically the number of blood vessels, number of endothelial cells and endothelial thickness.
METHODS: This study involved 41 diabetic foot patients admitted to Hospital Universiti Sains Malaysia for surgical management of foot problems. Skin biopsies were taken for histological evaluation following surgical procedures, such as wound debridement or local foot amputation. The skin microvasculature features examined were the number of blood vessels, the endothelial thickness of the vessels and the cross-sectional endothelial cell count. The findings were compared with the similar parameters of non-diabetic patients (control) and analysed.
RESULTS: The mean blood vessel count (BVC), endothelial cell thickness (ECT) and endothelial cell count (ECC) for the diabetic group were 12.56 +/- 2.77, 4.81 +/- 1.5 micrometres and 7.07 +/- 1.88, respectively. The mean BVC, ECT and ECC for the non-diabetic control group were 5.25 +/- 1.98, 1.9 +/- 0.55 micrometres and 4.11 +/- 1.17, respectively. The mean BVC, ECT and ECC for the diabetic group were significantly higher than those for the non-diabetic control group.
CONCLUSION: The increased number of blood vessels to the skin and their endothelial cell number and thickness may be the contributing factors for problems related to the diabetic foot, such as tendency for skin ulceration, infection and poor wound-healing in these patients. These may also contribute to secondary changes of diabetic foot lesions, indicating failure of adequate vascularisation of the foot.
