Many clinicians expect complete healing after the removal of temporary anchorage devices, but clinical examination may reveal scar-like tissue. This report presents the typical features of scarring detected after the removal of miniscrews, and the clinical outcome of scar revision along with its pathologic features.

OBJECTIVES: To compare the efficacy, safety and cost of locally-produced microcellulose dressing from Acetobacter xylinum in promoting healing of superficial partial thickness burn wounds to standard dressing using silver sulfadiazine (SSD) cream and gauze in terms of the following: time to healing, morbidity/infection rate, pain score, scarring and cost of dressing

METHODS: Comparative controlled trial. Each patient served as his own control, that is, one area was randomized to the treatment group dressed with microcellulose dressing, while another was assigned to the control group dressing with SSD. Both areas were inspected regularly for signs of infection, as well as reepithelialization. The patients were also asked for the pain score at rest, and during dressing using the visual analog scale. Once healed, the Vancouver scale was used to grade the resultant scars.

RESULTS: Ten patients were included from February to June 2008. All patients were males, with a mean age of 30.1 years (17-48 years, ± 12.05), and a mean total body surface involvement of 12.75% (4-22% TBSA,?± 7.0) superficial partial thickness burns. The time in days to complete reepithelialization was significantly lower in MCD dressings (p-value=0.05760). The mean times (in days) to complete reepithelialization for MCD and SSD were 11.4 (90 percent CI: 9.80-13.0) and 13.8 (90 percent CI: 12.33-15.27) days, respectively. Statistical analysis of differences of VAS scores during dressing changes were significantly lower in MCD dressing on days 2,6,9 and 12 post burn. Background VAS scores were also lower in those patients with MCD dressing on days 6, 9 and 12 post burn. None of the wounds in either treatment arm had signs of infection. Scarring of wounds dressed with MCD were better, based on the Vancouver scar score than those dressed with SSD (p = 0.0299). The means for the Vancouver score for MCD and SSD were 2.65 (90 percent CI: 2.25-3.05) and 4.05 (90 percent CI: 3.32-4.78), respectively.

CONCLUSION: Microcellulose dressing is significantly more effective than silver sulfadiazine in treatment of second degree burn wounds in terms of number of days to full reepithelialization and quality of scarring. Dressing with MCD was less painful on days 2, 6, 9 and 12 post burn. Background VAS scores were also lower on days 6, 9 and 12 post burn. None ofthe wounds in both treatment arms had signs of infection throughout the treatment period.

Recently, more and more clinical and basic studies have shown that early intervention of scars after wound healing can shorten the immature period of scars, improve the final outcome of scars, effectively prevent and control the occurrence and development of pathological scars. However, there are many methods for early management of scars with varying quality, and there is a lack of expert consensus on early scar management. Based on the existing clinical evidence of each intervention method and clinical experience of experts, more than 40 domestic experts from Standing Committee of Chinese Association of Plastics and Aesthetics Scar Medicine Branch have reached a consensus on definition, therapeutic principles, therapeutic methods, and other aspects of early scars after multiple discussions and revisions, providing reference for clinical treatment.

In recent years, there is a growing enthusiasm in honey which has potential health benefits, disease prevention and serves as substitution of modern medicine. Honey is a natural sweet product which is produced by honey bees from floral nectar and has been traditionally used to treat several diseases such as cardiovascular disease, diabetes mellitus, cancer and Alzheimer’s disease since ancient times. Gelam honey (GH) is one of the Malaysian wild monofloral honey which is widely used as traditional medicine by the local population. GH is enriched with several therapeutic properties namely, antioxidative, antiinflammatory, anticancer and accelerated wound healing activities. However, there is lack of literature focusing on the overall effects of GH and its medicinal value. This review paper summarises the phytochemistry characteristics of GH along with its therapeutic values which lead to a broad spectrum idea on several diseases. A concise clarification on the therapeutic properties of GH is expected to provide new knowledge to thescientific society in these modern globalization eras.

Objective: To evaluate the association of glycated haemoglobin (HbA1c) reduction and wound healing in patients with diabetic foot ulcer (DFU). Methodology: A 12-week prospective, non-controlled, interventional study in suboptimal-controlled T2DM patients with DFU was conducted. Antidiabetic medications were adjusted with the aim of at least 1% in relation to patient’s individualised HbA1c target. The wound area was determined by using specific wound tracing. The daily wound area healing rate in cm2 per day was calculated as the difference between wound area at first visit and the subsequent visit divided by the number of days between the two visits. Results: 19 patients were included in the study. There was a significant HbA1c reduction from 10.33 %+1.83% to 6.89%+1.4% (p<0.001) with no severe hypoglycaemia. The median daily wound area healing rate was 0.234 (0.025,0.453) cm2/day. There was a strong positive correlation between these two variables (r=0.752,p=0.01). After dividing the patients into four quartiles based on final HbA1c and comparing the first quartile vs fourth quartile, there was a significant difference in daily wound area healing rates (0.597 vs 0.044 cm2/day,p=0.012). Conclusion There was a positive correlation between HbA1c reduction and wound healing rate in patients with DFU. Although this is an association study, the study postulated the benefits of achieving lower HbA1c on wound healing rate in DFU which require evidence from future randomised controlled studies.

BACKGROUND: The degree of scar formation varies according to the sites. Oral mucosa heals faster with lesser scar formation than skin and it is very rare for oral mucosa to develop hypertrophic scars. Collagen gel seeded with fibroblasts is considered as a valuable model for studying wound healing in vitro. OBJECTIVE: The purpose of this study was to find out whether there are any differences in contractiliy of collagen gel by fibroblasts derived from different sites. METHODS: Fibroblasts were cultured from normal skin, oral mucosa, and hypertrophic scar. They were seeded into collagen gel with or without serum, and the degree of contraction of the collagen gel was measured for 5 days. RESULTS: Hypertrophic scar fibroblasts in collagen gel possessed the greatest contraction potency followed by normal skin fibroblasts and oral mucosal fibroblasts. Serum significantly increased the contractility of each of the fibroblasts. The differences of contractility of collagen gel between oral mucosal fibroblasts and others became more obvious in the presence of serum, however, those between normal skin fibroblasts and hypertrophic scar fibroblasts became less obvious. CONCLUSION: The degree of contraction of collagen gel by fibroblasts correlated with the degree of scar formation. Addition of serum modified the degree of contractile potency which may reflect the differences in the fibroblasts with phenotypic alteration and the subtype of fibroblasts.

PURPOSE: The mechanism of scar formation is not fully understood. Fibroblast is an important cell in wound healing process. We experienced a patient who was taking progesterone orally. Upper blepharoplasty was performed on her but, wound healing was delayed. We hypothesized that progesterone was the cause of delayed wound healing and fibroblast proliferation inhibition. We investigated the effect of progesterone in vitro on human dermal fibroblasts to study the effects on fibroblast proliferation. METHODS: Human dermal fibroblasts from four persons were cultured initially. Progesterone is mixed to them at various concentrations, and fibroblast cell count was measured by MTT assay method at 570nm. We confirmed that progesterone has some inhibitory effect on fibroblast proliferation and maximal inhibitory concentration of progesterone was determined. Then fibroblasts from a total of nineteen persons were cultured and the effects of progesterone were studied. RESULTS: The initial study showed the maximal inhibitory concentration of progesterone to be 50 microgram/ml. The main study showed that progesterone had 70.9% inhibitory effect on human dermal fibroblast in vitro. CONCLUSION: Progesterone has inhibitory effect on cultured human dermal fibroblast proliferation in vitro.

Keloids are fibrous overgrowth resulting from abnormal wound healing processes at the site of cutaneous injury. It extends beyond the confines of the original wound, begins later after injury, and does not regress with time contrary to hypertrophic scar. The gold standard has not been established in the treatment of keloids, yet. Excision of keloid alone showed a high rate of recurrence (45-100%). Recently, we have experienced two keloidal masses in the auricle (one on helix, the other on lobule), which were treated with surgery and adjuvant steroid injection. We developed an anteriorly-based skin flap from the skin covering of the keloidal mass and used it for several reasons. We also used triamcinolone injection after the surgery. In this paper, we are presenting the result of these cases with a review of literature.

After healing of burn wound, skin of scar, transplanted skin grafts, and healed donor site wound suffer from temporary or permanent loss of function of sebaceous glands and dysfunction of skin surface lipid film formation, resulting in desiccation, desquamation, and sensitiveness of the skin, making areas of newly formed skin unsatisfactory. Therefore a good rehabilitation may fail. In this paper, the composition, physiochemical properties, and reconstruction of skin surface lipid film are discussed.
