- Brief Summary
PURPOSE: to determine the impact of bee venom phonophoresis in accelerating ulcers healing.
BACKGROUND: Bee venom (BV) phonophoresis has been suggested as a noninvasive treatment for a number of inflammatory conditions and in healing of ulcers.
Ulceration due to vascular causes is often multifactorial and can be caused by both arterial and venous disease. Hypertension and atherosclerosis of the peripheral vessels lead to arterial disease associated with ischemic ulcers. Chronic venous insufficiency and the resulting venous hypertension cause venous ulcers.
There are lack in knowledge and information in published studies about the efficacy of bee venom phonophoresis as physical therapy modality in accelerating ulcers healing.
So, this study will be designed to provide a guideline about the efficacy of of bee venom phonophoresis in accelerating ulcers healing.
HYPOTHESES:
It will be hypothesized that:
It was hypothesized that Bee venom phonophoresis has no or limited effect in accelerating ulcers healing.
RESEARCH QUESTION: Does Bee venom phonophoresis an effect in accelerating ulcers healing?
- Detailed Description
• A verbal explanation about the importance of this research procedure, main aims and conceptual approaches were explained to every participant. • Every participant was given his written informed consent for bee venom phonophoresis treatment • The procedures of this study were divided into two main parts: part one (measurement procedures) and part two (treatment procedures).
Bee venom allergy test: The participants had been tested for BV allergy; diluted BV, 0.05 ml, in normal saline (1 mg/ml) was injected intra-dermally into the forearm. If the tested lesion resulted in a wheal with a diameter of less than 10 mm and erythema with a diameter of less than 26.5 mm after 10 to 15 minutes, subjects were participated in this study.
1. Measurement procedure:
A- Ulcer surface area Ulcer surface (UAS) would be calculated by placing a piece of sterilized transparency film over the ulcer and tracing the ulcer perimeter on the film with fine tipped transparency marker. A separate transparency was used for each Ulcer. The tracing is then placed over metric graph paper and the number of 1mm the tracing was counted (only full 1 millimeter squares inside the perimeter is counted and the area was converted to square centimeters).
Ulcer area was measured before the beginning of the study and at the end of the first and second months of therapy and this process was repeated a minimum of three times for each measurement with the value obtained two or more times was reported.
B-Ulcer volume measurement in cm3 (width x length x depth):
* The patient would be positioned in a relaxed position with the ulcer directed upward.
* The ulcer would be traced on transparent paper and placed over the metric graph paper to have the longest length and width.
* A measuring tape would be directed into the deepest point of the ulcer to record the ulcer depth.
* (width x length x depth)would be calculated to have the volume of the ulcer.

2. Treatment procedures:
Participants treated as outpatients, they were given information about the measurement and treatment procedures as well as about the bee venom phonophoresis before the beginning of the treatment, each participant history sheet was taken, they were asked to follow the surgeon and physical therapist instruction and asked to avoid heavy objects lifting as well as smoking.
Steps of the bee venom phonophoresis treatment procedures:
* Position of the participant: Put the participant in the most comfortable and relaxed position which is supine lying position then Remove any clothes above the abdomen to avoid restriction.
* Ultrasound device preparation: the plug of the ultrasound unit was inserted into the main current supply.
* Bee venom gel: the treatment approach (phonophoresis application for bee venom gel) had been prepared. Bee venom gel had been used for the study group and pure ultrasound gel had been used for the control group. Each participant received 0.6 mg up to maximum 1 mg BV gel each session • Phonophoresis application for bee venom gel (study group): A pulsed ultrasound (applicator 1.9 cm 2 ) had been applied around the incision site, the movement was over the incision margins with pulsed duty cycle 40% (4 ms on, 6 ms off), and Power density 0.5 W/cm2 and Time was 5 minutes each session. Treatment sessions were 3 sessions a week, for 3 consecutive weeks .
* Low intensity ultrasound with pure gel (control group): A low intensity pulsed ultrasound (applicator 1.9 cm 2 ) had been applied over the incision margins with pulsed duty cycle 20% (2 ms on, 8 ms off), and Power density 0.8 W/ cm 2 and Time was 5 minutes each session. Treatment sessions were 3 sessions a week, for 3 consecutive weeks 35 and medical treatment.

Group Intervention Description group A Bee venom phonophoresis received phonophoresis with Bee Venom gel in form of a noncontact low-frequency pulsed ultrasound delivered through Bee Venom gel as a topical treatment at a distance of between 5 and 15 mm from the ulcer wound bed, and time was 10 minutes for each session in addition to conservative treatment of medical ulcer care. group C low intensity ultrasound received a noncontact low-frequency pulsed ultrasound delivered through only plain gel without BV gel at a distance of between 5 and 15 mm from the ulcer wound bed, and time was 10 minutes for each session in addition to conservative treatment of medical ulcer care. group B Bee venom phonophoresis received phonophoresis with Bee Venom gel in form of a noncontact low-frequency pulsed ultrasound delivered through Bee Venom gel as a topical treatment at a distance of between 5 and 15 mm from the ulcer wound bed, and time was 10 minutes for each session in addition to conservative treatment of medical ulcer care.
- Primary Outcome Measures
Name Time Method The ulcer surface area changes from baseline, 6 weeks, 12 weeks of therapy. The ulcer surface area would be estimated by placing a piece of sterilized transparency film over the ulcer and using a fine-tipped transparency marker to trace the ulcer perimeter on the film. Each ulcer was treated with its own transparency. The trace was then placed on metric graph paper, and the count of 1mm squares within the perimeter was counted (only entire 1mm squares were counted, and the area was converted to square centimeters)
ulcer volume measurement changes from baseline, 6 weeks, 12 weeks of therapy. The patient would be in a comfortable position, with the ulcer facing upward. To have the longest length and width, the ulcer would be traced on translucent paper and placed over the metric graph paper. A disposable measuring tape would be directed into the deepest point of the ulcer to record the ulcer depth. The volume of the ulcer would be calculated to have the width x length x depth ratio
