Treatment of Surgical Scars with Nonablative Fractional Laser Versus Pulsed Dye Laser: A Randomized Controlled Trial

DERMATOLOGIC SURGERY, Issue 8 2009
EMILY TIERNEY MD
OBJECTIVE Comparison of the efficacy of nonablative fractional laser (NAFL) and the V-beam pulsed dye laser (PDL) for improvement of surgical scars. METHODS A randomized blinded split-scar study. Fifteen scars in 12 patients were treated a minimum of 2 months after Mohs surgery. Patients were treated on half of the scar with a 1,550-nm NAFL and on the contralateral half with the 595 nm PDL. MAIN OUTCOME MEASURE(S) A nontreating physician investigator evaluated the outcome of the scar in terms of scar dyspigmentation, thickness, texture, and overall cosmetic appearance (5-point grading scale). RESULTS After a series of four treatments at 2-week intervals, greater improvements were noted in the portion of surgical scars treated with NAFL (overall mean improvement 75.6%, range 60,100%, vs. PDL, 53.9%, range 20,80%; p<.001). CONCLUSION These data support the use of NAFL as a highly effective treatment modality for surgical scars, with greater improvement in scar appearance than with PDL. It is likely that the greater depth of penetration and focal microthermal zones of injury with NAFL, inducing neocollagenesis and collagenolysis, account for its greater improvement in scar remodeling. These encouraging results lead us to recommend that NAFL be added to the current treatment armamentarium for surgical scars. [source]

Late-onset Papillon,Lefevre syndrome with pyogenic liver abscesses: report of one case

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 1 2009
Ameneh Yazdanfar MD
A 25-year-old woman living in Hamedan, Iran, presented originally at 7 years of age with erythematous, hyperkeratotic lesions on the palms and soles with extension to the dorsal side of the hands and feet. Involvement of the elbows and knees was also seen. From 12 years of age, she started to lose her teeth. At the same age, she experienced fever, chills, malaise, myalgia, and right upper quadrant abdominal pain. With a diagnosis of pyogenic liver abscesses, the patient underwent successful surgical treatment. ,Examination revealed erythematous, hyperkeratotic, scaling plaques on the palms and soles, dorsal side of the hands and feet (Fig. 1), elbows and knees. All the teeth were missing from the mouth (Fig. 2), and she used a dental prosthesis. A surgical scar was observed on the right upper quadrant of the abdomen (Fig. 3). Skull X-ray and computed tomography scan were normal. Skin biopsy of the dorsal right hand demonstrated hyperkeratosis, focal parakeratosis, hypergranulosis, and acanthosis with a mild inflammatory infiltrate around the vessels (Fig. 4). Figure 1.

Adverse reaction to surgical sutures in thyroid surgery

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 1 2003
Eitan Hocwald MD
Abstract Background. A mild reaction to surgical sutures after thyroid surgery is common and is characterized by local edema and inflammation around the surgical scar. Severe reaction with microabscesses and granulomatous masses is quite rare. Methods and Results. Two cases of severe reaction to silk sutures after thyroid surgery are presented. Meticulous surgical removal of all surgical sutures along with granulomatous masses, granulation tissue, and microabscesses cured both patients. Pathologic examination revealed giant cells and lymphocytes. Intradermal skin tests were positive to silk sutures. The etiology and the treatment options are discussed. Conclusions. In rare cases, severe reaction to silk sutures may develop after thyroid surgery. Surgical removal of the stitches is the treatment of choice. Intradermal skin test is a good predictor of allergy to sutures. © 2002 Wiley Periodicals, Inc. Head Neck 24: 000,000, 2002 [source]

Mechanisms of Right Atrial Tachycardia Occurring Late After Surgical Closure of Atrial Septal Defects

JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 7 2005
ISABELLE MAGNIN-POULL M.D.
Introduction: In patients without structural heart disease, the most frequently occurring AT is the common atrial flutter. In patients with repaired congenital heart disease other mechanisms of AT may occur, due to the presence of an atriotomy that can provide a substrate for reentry. The aim of the present study was to identify the mechanisms of atrial tachycardia (AT) occurring late after atrial septum defect (ASD) repair, with the help of a three-dimensional electroanatomical mapping system. Methods and Results: Twenty-two consecutive patients presenting with AT underwent complete electroanatomic mapping (CARTO®, Biosense Webster, Diamond Bar, CA) of spontaneously occurring and inducible right ATs. Complete maps of 26 ATs were obtained. Three tachycardia mechanisms were identified: single-loop macroreentrant atrial tachycardia (MAT) (n = 7), double-loop MAT (n = 18), and focal AT (n = 1). In all MATs, protected isthmuses were identified as the electrophysiological substrate of the arrhythmia, most frequently the cavotricuspid isthmus (CTI) (n = 24), and a gap between the inferior vena cava and a line of double potentials (n = 11). A mean number of 13.5 ± 2.1 radiofrequency applications were delivered to transect these critical parts of the circuit. During a follow-up of 25 ± 16 months the RF ablation was acutely successful in all patients. Thirteen patients (59%) had an early recurrence of MAT and needed an additional ablation procedure. One of those patients needed two additional ablation procedures. Conclusions: Three-dimensional electroanatomic mapping is useful to identify postsurgical AT mechanisms; the CTI isthmus is involved in 92% MAT, and if the right atrial free wall (RAFW) abnormal tissue related to surgical scar is present this substrate contributes to the MAT circuit [source]

Recurrent keratoacanthoma with vascular invasion: A diagnostic and management dilemma

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2009
Anil Kurien
ABSTRACT A 71-year-old man with chronic renal failure and on peritoneal dialysis presented with recurrence of multiple keratotic nodules along a surgical scar. This was 6 months after the excision of a recurrent keratotic nodule reported as squamous cell carcinoma from the same site. The lesions were initially reported as squamous cell carcinomas, but on review of histology were consistent with keratoacanthomas. One of the keratoacanthomas showed vascular invasion. These responded well to low-dose acitretin at 10 mg three times per week and the patient stayed in remission after 18 months of follow up. [source]

4268: Metadifferentiation of iris nevi after iridectomy: a clinicopathological small case series.

ACTA OPHTHALMOLOGICA, Issue 2010
A SCHALENBOURG
Purpose Iridectomy of suspicious pigmented tumors provides the presumed advantage of both a histopathological diagnosis and treatment of the lesion. We present 2 patients that developed an iris melanoma with extrascleral extension at the site of their iridectomy of a histopathologically proven nevus, 46 and 2.5 years later. Methods Retrospective, clinicopathological small case series of 2 patients. Results Two patients underwent iridectomy for a suspicious tumor, the first in 1963 and the second in 2006. Pathological diagnosis was a benign and a borderline nevus respectively. In 2009, both patients presented with a recurrent melanocytic iridociliary tumor with an extrascleral extension adjacent to the surgical scar. Pathological examination confirmed melanoma. Consequently, the two patients underwent proton beam therapy of the whole anterior segment, with limbus deposition and reposition. Conclusion Iridectomy of a histopathologically proven nevus doesn't exclude the possibility of a metadifferentiation of remaining nevus cells into melanoma, even after 46 years. Additionally, treatment in case of a recurrence is more complicated than a primary radiotherapy of the unbiopsied iris tumor, with clinical proof of growth, would have been. [source]

585-nm Pulsed Dye Laser in the Treatment of Surgical Scars Starting on the Suture Removal Day

DERMATOLOGIC SURGERY, Issue 1 2003
Keyvan Nouri MD
Background The optimal time frame to improve the quality and cosmetic appearance of scars by laser therapy has not been clearly elucidated by prior controlled clinical trials. Objective To determine the efficacy of the 585-nm pulsed dye laser (PDL) in the treatment of surgical scars starting on the day of suture removal. Methods Eleven patients (skin types I,IV) with 12 postoperative linear scars that were greater than 2 cm were treated three times on monthly intervals with the 585-nm PDL (450 ,s, 10-mm spot size, 3.5 J/cm2 with 10% overlap) on one scar half, whereas the other half received no treatment. Scars were later evaluated by a blinded examiner using the Vancouver Scar Scale (VSS) for pigmentation, vascularity, pliability, and height. Scars were then blindly examined for cosmetic appearance using a visual analog scale. Results One month after the last treatment, final scar analysis by the blinded examiner revealed a significant difference between treated and untreated sites, with the treated halves scoring better in all scar parameters in the VSS and in cosmetic appearance. The treated halves demonstrated an overall average improvement in the VSS between the first treatment score and the final score of 54% versus 10% in the controls (P=0.0002). The cosmetic appearance score (0=worst; 10=best) at final assessment was significantly better for the treated scars, scoring 7.3 versus the averaged control score of 5.2 (P=0.016). Conclusion The 585-nm PDL is effective and safe in improving the quality and cosmetic appearance of surgical scars in skin types I,IV starting on the day of suture removal. [source]
