Scar Management

Introduction: Scar treatments aim to address pathologic collagen deposition; however, they can be expensive or difficult to control. Electrochemical therapy (ECT) offers a simple alternative treatment. The purpose of this study is to examine the acid-base and histological changes in ex vivo human abdominal skin following ECT. Methods: Forty-two ex vivo human panniculus tissue sections collected from six individuals were tumesced with normal saline. ECT was performed by inserting two platinum needle electrodes connected to a DC power supply into each specimen. Voltage was varied (3–6 V) and applied for 5 minutes. Each specimen was sectioned across both electrode insertion sites and immediately stained with pH sensitive dye. The width of dye color change for each dosimetry pair was calculated. Hematoxylin and eosin staining was used to evaluate samples. Results and Discussion: ECT caused a spatially localised and dose-dependent increased area of acidic and basic pH around the anode and cathode, respectively. A significantly greater mean width of pH change was generated at the cathode compared to the anode in all treatment groups. Histological evaluation displayed broad condensation and hyalinisation of dermal collagen. Conclusion: ECT triggered dermal pH alterations and changed the underlying structural framework of the specimen. This technology may serve as a low-cost, minimally invasive local soft-tissue remodeling technique with potential application in scar management. Level of Evidence: 5 Lay Summary Electrochemical therapy is a novel treatment that causes spatially selective dermal injury in areas of interest. This study measures the effects of electrochemical therapy when applied to abdominal skin. Electrochemical therapy appears to have beneficial effects by causing a highly localised reduction in collagen content or local softening of tissue, which is consistent with other studies on scar therapies, including chemexfoliation, radiofrequency technologies, and lasers. However, electrochemical therapy can be performed at a fraction of the costs of these aforementioned modalities.

Normal Sensitivity

The urinary excretion of histamine was found to rise rapidly in rats exposed to cold (6 C). A sevenfold increase above normal is maintained during the 1st month of exposure, but during the 2nd month a decline from these high values is observed, and after 1 year the urine histamine is within normal limits. Similarly, a marked increase in the number of mast cells in the abdominal skin is observed during the first 2 months of cold exposure with a return to initial values by the 4th month. The blood pressure response to intravenous histamine is decreased during the 1st month of cold adaptation but after 1 year in the cold normal sensitivity to histamine is re-established. The excretion of 5-hydroxytryptamine is also rapidly increased during cold adaptation but no decline with time was observed. These findings obtained with histamine are compared with those found previously with noradrenaline. Whereas the urinary levels of these amines show similar variations during cold adaptation, the cardiovascular response differs. The sensitivity to histamine is decreased with increased excretion and the response to noradrenaline increased with increased secretion.

Abdominal Liposuction

A retrospective study of 100 patients who underwent abdominal liposuction under local anesthesia from 1991 to 1995 is presented. All patients were overweight and had redundant abdominal skin fold. With the advent of superficial liposuction plus adequate and strict garment usage in the postoperative period we believe that abdominoplasty is rarely indicated in this type of patient. There is marked abdominal skin retraction after superficial liposuction. The results are excellent as can be seen with pre- and postoperative photographs. By avoiding abdominoplasty some complications can be minimized, such as pulmonary embolism, pulmonary fat embolism, and hypovolemic shock, as well as “minor” complications like anemia, blood transfusion, long scars (stigma), wound dehiscence, hematomas, seromas, atelectasis, and nerve damage. With liposuction, general anesthesia, with long and painful recovery and time away from work, may be avoided. Patients are very grateful when they are told that their abdominal deformity can be corrected with no major risks, and with fast recovery.
