Scars can cause great psychological stress among patients. Currently, there are numerous topical agents, laser and surgical treatments available for skin rejuvenation and scar minimization. Laser-assisted drug delivery (LADD) is a treatment method that increases drug delivery by stimulating the skin physically and chemically to enhance the penetration of topical agents. This is one of the areas of great interest in the treatment of various skin diseases in addition to its use for cosmetic purposes. In particular, LADD is relatively non-invasive and has advantages in terms of accessibility and stability. Poly-L-lactic acid (PLLA) is a collagen stimulator known to gradually restore skin volume by inducing inflammation and fibroplasia. Herein, we report a case of treatment of an atrophic scar with fractional carbon dioxide laser-assisted PLLA delivery.

Purpose : An atrophic renal scar(RS) is one of the underlying causes for childhood hyper tension and chronic renal failure. The risk factors for atrophic renal scar were evaluated. Methods : 41 children, who presented with first febrile urinary tract Infection at the Ewha Womans University Hospital between 1995 and 2003 and had generalized atrophic RS on $^{99m}Tc-DMSA$ renal scan, were retrospectively studied. Atrophic RS was divided into severe atrophic RS(n=14) if relative uptake on renal scan was below 10$\%$, or mild atrophic RS(n=27) if relative uptake on renal scan was between 10-35$\%$. RS was defined as congenital if the scar was detected on the first renal scan, and as acquired if the scar developed on the follow-up renal scan from acute pyelonephritis of the first renal scan. The control group was consisted of randomly selected 41 children with segmental RS. The risk factors for atrophic RS such as the generation time, VUR, gender and ACE gene polymorphism were evaluated. Results : The age distribution of atrophic RS and segmental RS did not differ significantly (P>0.05). The rate of congenital RS in atrophic RS was 61.0$\%$(25/41), which was significantly higher than 9.8$\%$(4/41) of segmental RS(P<0.01). Atrophic RS developed mote frequently in male children(M:F 68.3$\%$ 31.7$\%$) than segmental RS(M:F 41.4$\%$ .58.5$\%$)(P<0.05). Vesicoureteral reflux(VUR) was found in 92.7$\%$(38/41) of 4he atrophic RS, which was significantly higher than 53.7$\%$(22/41) of segmental RS(P<0.05). In children without VUR, the male to female ratio did not differ between atrophic RS and segmental RS(P>0.05) But in children with VUR, there was a higher proportion of males with severe atrophic RS than segmental RS($85.7\%:45.5\%$) ACE gene polymorphism did not differ between the atrophic and segmental RS groups, irrespective of the presence of VUR(P>0.05). Conclusion : Most atrophic RSs were congenital which could not be preventable postnatally and the major risk factors were VUR and the male gender. ACE gene polymorphism was not the significant risk factor for an atrophic RS. (J Korean Soc Pedialr Nephrol 2005;9:193-200)

Background and Objective : Atrophic scars are the most common complication of acne. Many modalities are proposed but each does not yield satisfactory clinical outcomes. Among therapeutic modalities of acne scars, subcision is a simple, safe procedure with a different and basic mechanism for correcting atrophic and depressed scars. However, there are few reports about such procedure. This study performed to evaluate the effect of subcision treatment on atrophic acne scar. Methods : Five patients with atrophic acne scars of various types(rolling, superficial and deep boxcar, pitted and icepick) were treated by superficial dermal undermining with 25~27 gauge needles. We used GASC(Global Acne Scarring Classification). Satisfaction degree was asked from the patients. Results and Conclusions : After observing patients satisfaction, comparing case photos and GASC, it can be considered that subcision treatment brings great results when performed on atrophic post acne scars.

Objectives : The purpose of this study is to present the effect of subcision, microneedle therapy system and herbal peeling therapy which is treatment of Korean medicine to atrophic acne scar patients. Methods : We administered subcision, microneedle therapy system and herbal peeling therapy to atrophic acne scar patients and tested the results by Qualitative Global Acne Scarring Grading System and Korean Acne Grading System as well. Results : After the treatment, all of the patients showed improvements in Qualitative Global Acne Scarring Grading System and Korean Acne Grading System as well. Qualitative Global Acne Scarring Grading System of patients changed from grade 2.71±0.71 to grade 1.14±0.86 along with the change of Korean Acne Grading System from grade 1.57±0.57 to grade 1.00±0.00. Conclusions : Subcision, microneedle therapy system and herbal peeling therapy may be effective in the treatment of moderate to severe acne scars, and could be applied in clinical practice.

Objective : The aim of this study is to report the effect of Hani-maehwa laser(fractional mode) treatment on acne scar. Methods : The patient with atrophic facial acne scars was treated with 5 sessions of laser therapy at 4-week intervals. The therapeutic response to treatment was assessed at 3 months after last laser session. The treatment effect was evaluated by standardized photography, anti aging, skin brightness and flatness. That was measured by micro fluorescence measurement camera(ECO SKIN, Cuvitz Inc.) in 16(left zygoma) and 26(right zygoma) spot. And side effects were also checked. Results : Atrophic facial acne scars have improved markedly. Anti aging, skin brightness and flatness were improved. Especially anti aging and flatness were noticeably improved. Adverse effects were not reported.Conclusions : Korean medicine cautery method applies to high level laser(CO₂ Hani-maehwa laser). These are different designs but same principle. It can be considered that laser therapy is effective method for treating acne scars.

Objective: Acne scarring is the most common sequela after dermal inflammation caused by acne. Many methods are currently used to treat acne scarring; doctors using traditional Korean medicine have also attempted to treat acne scarring in a new way that was developed from traditional methods. This study examines the effectiveness of re-cell therapy.Method: Eleven patients with various types of acne scars were treated by re-cell therapy. We used the global acne scarring classification (GASC) and ECCA (from the French “echelle d’evaluation clinique des cicatrices d’acne”), both of which are generally used to measure and grade the degree of acne scarring.Results: As a result of the treatment, the conditions of all patients were conspicuously improved in both scales. The GASC scores of the patients changed from grade 19.6±10.4 to grade 4.9±3.3 (p=0.001), and the ECCA scores changed from grade 120.9±28.7 to grade 41.8±18.3.Conclusion: Re-cell therapy showed effectiveness in treating acne scarring and could be applied in clinical cases.
