ABSTRACT
Background: Percutaneous collagen induction [PCI] promotes removal of damaged collagen and induces more collagen immediately under the epidermis. The chemical reconstruction of skin scars [CROSS] method is a focal application of full-concentration trichloroacetic acid [TCA] to atrophic acne scars. The CROSS method has the advantage of reconstructing acne scars by increasing dermal thickening and collagen production
Objective: To compare the safety and efficacy of PCI and the 80% TCA CROSS method for the treatment of atrophic post acne scars
Patients and Methods: Thirty four participants were randomly divided into two groups; group 1[19 patients] underwent four sessions [4 weeks apart] PCI, and group 2 [15 patients] underwent five sessions [2 weeks apart] of 80% TCA CROSS. The two groups were compared regarding photo evaluation, patient satisfaction and adverse effects
Results: All patients improved in both groups. However, the mean percentage of improvement was statistically significantly higher in the first group treated by the dermaroller [59.89%] than in the second group treated by TCA CROSS 80% [42.73%] [p = 0.025] but there was no statistical significant difference regarding the patient satisfaction
Conclusions: PCI and 80% TCA CROSS were effective in the treatment of atrophic acne scars with superior results were in favor of dermaroller

<p><b>OBJECTIVE</b>To analyze the management of high-voltage electrical burn injury of the scalp in our hospital.</p><p><b>METHODS</b>This study involved 10 patients who suffered from high-voltage electrical burn injury of the scalp. Scalp reconstruction was done by different modalities according to the size and location of the defect.</p><p><b>RESULTS</b>Complete flap viability was achieved in all the cases. We had one case of gapped wound which was managed only by dressing. Widening of the scar was found in 2 cases.</p><p><b>CONCLUSION</b>Rotation, advancement and transposition scalp flaps are used for reconstructing scalp defects caused by electrical burn. The choice of ideal flaps for reconstruction depends upon the size and site of scalp defect.</p>
