ABSTRACT The extract of oak bark (QRB7) has been used for years as a topical medication with success. QRB7 is the proprietary oak bark extract in Bensal HP. It is indicated as an external treatment for the inflammation and irritation associated with many common forms of dermatitis, including certain eczematoid conditions. These conditions include complications associated with pyodermas, and in the treatment of insect bites, burns, and fungal infections.
To quantitatively measure the difference in diabetic ulcer size reduction when using Bensal HP versus silver sulfadiazine cream (SSC) for topical treatment as an adjunct to conventional treatment.

Forty diabetic patients with noncellulitic plantar Wagner grade 1 or 2 ulcers and a minimal ankle brachial index of 0.75 were randomly assigned to either the Bensal HP (QRB7) treatment group or SSC control group for 6 weeks of treatment. In addition to either Bensal HP or SSC, all wounds were cultured and treated with debridement at time 0, 2, 4, and 6 weeks and with off-loading.
The combined wound diameter of the Bensal HP group decreased 72.5% compared to 54.7% for the SSC group. There was a statistical significance between the decreases in wound sizes after 6 weeks of treatment (P = .016). The Cohen effect size for the Bensal HP group was 2.06 compared with 1.03 for the SSC group.
In this tightly controlled 6-week study in which no patients were lost to follow-up, Bensal HP seems to be an effective treatment for properly treated diabetic ulcers, outperforming an identical control group whose only difference was SSC as a medication.

    ABSTRACT: MEDICATION SAFETY Overlooked Renal Dosage Adjustments A retrospective analysis of 647 patients at hospital discharge com-pared required renal dosage adjust-ments to dosage actually prescribed. This study was conducted at VieCuri Medical Centre in Venlo, Netherlands. Patient demographics and renal function data were col-lected, and dosage adjustment needs were assessed via the pharmacy-supported discharge counseling ser-vice. The incidence of inappropriate dosing based on renal function was measured at hospital discharge. Thirty-seven percent of patients evaluated during the study period (237/647) had a creatinine clear-ance less than 51 mL/min/1.73 m 2 ; dosage adjustment was warranted in 23.9% (411/1,718) of prescrip-tions. When dosage adjustment should have been performed, more than 40% of prescriptions (169/411; 41.1%) were inappropri-ate for renal function (9.8% of pre-scriptions overall; 169/1,718). Fur-thermore, 60.4% (102/169) of inappropriate prescriptions pos-sessed the potential for moderate or severe clinical consequences, as evaluated by a panel of two clinical pharmacologists and one nephrolo-gist. Study authors also noted a lack of standardized dosing guidelines for agents requiring renal dosage adjustment. The authors also sug-gested that augmenting medication systems by adding dynamic renal dosing alerts would improve moni-toring. Summary: A comparison of suggested renal dosing and actual dosing at hospital discharge revealed that appropriate prescribing may be overlooked. van Dijk EA, Drabbe NRG, Kruijtbosch M, De Smet PAGM.

    ABSTRACT: The outcome of management of diabetic foot ulcers is poor and there is uncertainty concerning optimal approaches to management. We have undertaken a systematic review to identify interventions for which there is evidence of effectiveness. A search was made for reports of the effectiveness of interventions assessed in terms of healing, ulcer area or amputation in controlled clinical studies published prior to December 2006. Methodological quality of selected studies was independently assessed by two reviewers using Scottish Intercollegiate Guidelines Network (SIGN) criteria. Selected studies fell into the following categories: sharp debridement and larvae; antiseptics and dressings; chronic wound resection; hyperbaric oxygen (HBO); reduction of tissue oedema; skin grafts; electrical and magnetic stimulation and ultrasound. Heterogeneity of studies prevented pooled analysis of results. Of the 2251 papers identified, 60 were selected for grading following full text review. Some evidence was found to support hydrogels as desloughing agents and to suggest that a systemic (HBO) therapy may be effective. Topical negative pressure (TNP) may promote healing of post-operative wounds, and resection of neuropathic plantar ulcers may be beneficial. More information was needed to confirm the effectiveness and cost-effectiveness of these and other interventions. No data were found to justify the use of any other topically applied product or dressing, including those with antiseptic properties. Further evidence to substantiate the effect of interventions designed to enhance the healing of chronic ulcers is urgently needed. Until such evidence is available from robust trials, there is limited justification for the use of more expensive treatments and dressings.

    ABSTRACT: Wound dressings and creams containing silver are widely used. It is thought that silver may help wounds to heal faster and prevent infection, but we did not know if this was true. This review identified 26 trials (involving 2066 participants) comparing silver-containing dressings or creams against dressings or creams that did not contain silver. Twenty of the trials were on burn wounds, while the other trials were on a mixture of wound types. Most studies were small and of poor quality. After examining them all, the authors concluded that there is not enough evidence to support the use of silver-containing dressings or creams, as generally these treatments did not promote wound healing or prevent wound infections. Some evidence from a number of small, poor-quality studies suggested that one silver-containing compound (silver sulphadiazine) has no effect on infection, and actually slows down healing in patients with partial-thickness burns.
