A prospective randomized controlled trial comparing negative pressure dressing and conventional dressing methods on split-thickness skin grafts in burned patients

INTRODUCTION Split-thickness skin grafting (SSG) is a technique used extensively in the care of burn patients and is fraught with suboptimal graft take when there is a less-than-ideal graft bed and/or grafting conditions. The technique of Negative Pressure Dressing (NPD), initially used for better wound healing has been tried on skin-grafts and has shown to increase the graft take rates. However, comparative studies between the conventional dressing and vacuum assisted closure on skin grafts in burn patients are unavailable. The present study was undertaken to find out if NPD improves graft take as compared to conventional dressing in burns patients. MATERIALS AND METHODS Consecutive burn patients undergoing split-skin grafting were randomized to receive either a conventional dressing consisting of Vaseline gauze and cotton pads or to have a NPD of 80 mm Hg for four days over the freshly laid SSG. The results in terms of amount of graft take, duration of dressings for the grafted area and the cost of treatment of wound were compared between the two groups. RESULTS A total of 40 split-skin grafts were put on 30 patients. The grafted wounds included acute and chronic burns wounds and surgically created raw areas during burn reconstruction. Twenty-one of them received NPD and 19 served as controls. Patient profiles and average size of the grafts were comparable between the two groups. The vacuum closure assembly was well tolerated by all patients. Final graft take at nine days in the study group ranged from 90 to 100 per cent with an average of 96.7 per cent (SD: 3.55). The control group showed a graft take ranging between 70 and 100 percent with an average graft take of 87.5 percent (SD: 8.73). Mean duration of continued dressings on the grafted area was 8 days in cases (SD: 1.48) and 11 days in controls (SD: 2.2) after surgery. Each of these differences was found to be statistically significant (p<0.001). CONCLUSION Negative pressure dressing improves graft take in burns patients and can particularly be considered when wound bed and grafting conditions seem less-than-ideal. The negative pressure can also be effectively assembled using locally available materials thus significantly reducing the cost of treatment.

Comparison of intralesional verapamil with intralesional triamcinolone in the treatment of hypertrophic scars and keloids

BACKGROUND The calcium channel blocker, verapamil stimulates procollagenase synthesis in keloids and hypertrophic scars. AIM To study the effect of verapamil in the treatment of hypertrophic scars and keloids and to evaluate the effect of verapamil on the rate of reduction of hypertrophic scars and keloids in comparison with triamcinolone. METHODS The study was a randomized, single blind, parallel group study in which 54 patients were allocated to to receive either verapamil or triamcinolone. Drugs were administered intralesionally in both groups. Improvement of the scar was measured using modified Vancouver scale and by using a centimeter scale serially till the scar flattened. RESULTS There was a reduction in vascularity, pliability, height and width of the scar with both the drugs after 3 weeks of treatment. These changes were present at one year of follow-up after stopping treatment. Scar pigmentation was not changed desirably by either drug. Length of the scars was also not altered significantly by either drug. The rate of reduction in vascularity, pliability, height and width of the scar with triamcinolone was faster than with verapamil. Adverse drug reactions were more with triamcinolone than with verapamil. CONCLUSION Intralesional verapamil may be a suitable alternative to triamcinolone in the treatment of hypertrophic scars and keloids.

Correction of post burns contracture of wrist with Ilizarov method

A case of severe post burns contracture of the wrist, of 43 years duration resulting in recurrent ulceration of the skin was successfully treated by gradual distraction using the Ilizarov method. This method is superior to plaster of Paris cast and is more versatile than other forms of external fixation.

Vacuum closure as a skin-graft dressing: a comparison against conventional dressing

BackgroundGrafting condition is one of the important determinants of skin-graft take. The technique of Vacuum-Closure has been claimed to improve the same and thereby graft take. However, there are few comparative studies against the conventional dressing technique evaluating its effectiveness in skin grafting. The present study was undertaken to compare Vacuum-closure with conventional dressing over freshly laid split-skin grafts.MethodsConsecutive patients undergoing split-skin grafting were randomized into cases and controls. The grafts in controls were covered by a conventional dressing consisting of vaseline gauze and cotton pads. Those in cases were covered by a vacuum-closure assembly and connected to a wall-suction of 80 mm Hg continuously for four days. The percentage of graft take was assessed at nine days and at two weeks and duration of the dressing were compared between the two groups. The difference in cost of the dressing was noted down.ResultsSixty four patients underwent split skin grafting of 71 wounds. Forty three of them were males and twenty nine were females. The grafted wounds included fresh surgically created wounds, traumatic wounds, acute and chronic burn wounds, post-inflammatory wounds and diabetic wounds. Thirty five of the grafts were cases and 36 were controls. Final graft take at two weeks in the study group ranged from 70-100 per cent with an average of 95.29 per cent graft take (SD: 5.9) while the control group showed a graft take ranging between 0-100 percent with an average graft take of 85.89 percent (SD: 25.1) Duration of dressing of the grafts was 11.63 days in cases as against 15.11 days in controls. The differences were statistically significant. The additional cost of the vacuum-closure assembly for an average sized ulcer was 6.27 pounds.ConclusionNegative pressure dressing increases the amount of graft take and should be used particularly when the wound bed and grafting conditions seem less-than-ideal for a complete graft take. Negative-pressure dressing can be economically and effectively assembled using locally available materials.Level of Evidence:Level I, therapeutic study.

Chondroid syringoma with extensive ossification

Chondroid syringoma is a rare appendagel skin tumor. Due to its uncharacteristic presentation, it is rarely diagnosed clinically. Here we present one such case in a 50-year-old lady. She presented with a hard mobile lesion over her nose which was excised. The histologic picture is characterized by a combination of epithelial and myoepithelial structures within a chondromyxoid and fibrous stroma. For these tumors, excision is the treatment of choice.

Groin reconstruction after inguinal block dissection

Inguinal block dissection is a necessary component in the treatment of certain cancers. Cancer of the penis is not an uncommon malignancy in the Indian subcontinent and while no one questions the treatment of the primary lesion, the need to remove the inguinal lymph glands concurrently, remains a matter of great controversy. Never the less, the survival of patients with penile cancer depends solely on the presence or absence of metastasis to the inguinal lymph nodes. The hesitation in offering inguinal lymph node dissection in every case is significantly related to the morbidity of the procedure in an attempt to reduce these complications, skin flaps can be used to cover the groin. This article looks at various flaps that can be used in groin reconstruction.

Abstract An adequate increase in oxygenation has been achieved by using facemask CPAP therapy in three burn patients with refractory hypoxaemia following sepsis, obviating the need for endotracheal (ET) intubation.

Heminasal aplasia: A report of two cases.

Heminasal aplasia is a rare congenital malformation. It is often associated with other malformations of the facial region, including abnormalities of the eye and lacrimal system, facial bone malformations and proboscis lateralis. We present two cases of heminasal aplasia, discuss their embryological basis and nasal reconstruction of the same.

Mammoth orbitofrontal neurofibromatosis with herniating meningo-encephalocele

We are presenting a mammoth orbito-frontal neurofibroma with a herniating meningo-encephalocele in a 23 year old African male. The tumour measured 87cm x 54cm and occupied the right orbito-temporo-facial region and had destroyed the right orbit. A pre operative embolization of the feeding vessels was followed by a one stage near total excision of the tumour and repair of the meningo-encephalocele in hypotensive anaesthesia. The excised tumour weighed 8 Kg and, to the best of our knowledge, is the largest orbito-facial neurofibroma reported in literature.
