Verruga plantar recalcitrante tratada exitosamente con una sesión de láser PDL / Recalcitrant plantar wart treated successfully with a PDL laser session

Las verrugas plantares son una patología común en la población. Estas lesiones son a menudo dolorosas y recidivantes. Entre los tratamientos más utilizados están las terapias tópicas destructivas, y menos frecuentemente, el tratamiento quirúrgico. Sin embargo, con frecuencia recurren, por lo que representan un desafío para los dermatólogos. Se presenta a un paciente de 29 años con una verruga plantar recalcitrante que fue tratada exitosamente con una sesión de láser PDL, sin recidiva luego de 12 meses de seguimiento.

Plantar warts are a common pathology in the population. These lesions are often painful and recurring. Among the most used treatments are topical destructive therapies, and less frequently, surgical treatment. However, they frequently recur, so they represent a challenge for the dermatologist. A 29 years old patient is presented with a recalcitrant plantar wart that was successfully treated with a single PDL laser session, without relapse after 12 months of follow-up.

Tratamiento con Pulsed Dye Laser de mancha de vino oporto: seguimiento a 10 años / Treatment with Pulsed Dye Laser of wine stain Porto: 10-year follow-up

Las manchas de vino de oporto son un tipo de malformación capilar que afecta del 0,3 al 0,5% de la población. Están presentes desde el nacimiento como máculas o placas eritematosas en la piel o mucosas. Sin tratamiento, las lesiones tienden a oscurecerse con la edad, tornándose rojizas o color púrpura, y pueden desarrollar engrosamiento nodular o un granuloma piógeno asociado. Los tratamientos con láser proporcionan mejoría mediante la destrucción selectiva de la vasculatura. Se han utilizado una variedad de láseres vasculares selectivos, pero el tratamiento de primera elección es el láser de colorante pulsado. Los mejores resultados se obtienen cuando el tratamiento es instaurado tempranamente. (AU)

Port wine stains are a type of vascular malformation that affects 0.3% to 0.5% of the population. They are present from birth as erythematous macules or plaques on the skin or mucous membranes. Without treatment, these lesions tend to darken with age, becoming reddish or purple and may develop nodular thickening or an associated pyogenic granuloma. Laser treatments might provide an improvement by selective destruction of the vasculature. A variety of selective vascular lásers may be employed, with the pulsed dye laser as the gold standard treatment. Better results are obtained when the treatment is established early. (AU)

Two Cases of Mucosal Bridge Crossing the Membrane of Vocal Folds / 대한이비인후과학회지

Mucosal bridges of vocal fold have been described as a parallel band to vocal folds with the presence of sulcus vocalis. However, the type of mucosal bridge crossing each vocal fold has not been well documented in the literature. Herein, we present two cases of mucosal bridge found in the vocal fold connecting the mid-portions of true vocal folds. Two patients who had no history of laryngeal trauma, surgery or oro-tracheal intubation visited our clinic due to voice change. Laryngoscopic examination revealed that they had a mid-portion mucosal band without any other mucosal lesions. Two patients underwent laryngomicrosurgery with pulsed dye laser. After the surgery, they showed significant improvement of voice quality.

Nail psoriasis treated with pulsed dye laser

Abstract: Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by the Nail Psoriasis Severity Index (NAPSI). The median improvement in the scores of the overall NAPSI, nail bed NAPSI, and nail matrix NAPSI were 44.2% (P = 0.002), 50% (P = 0.033) and 65.1% (P = 0.024), respectively.

Surgical Treatment of Sulcus Vocalis Using KTP Laser

Sulcus vocalis remains a surgical challenge despite many recent advances in laryngomicrosurgeries. We previously reported that 585-nm Pulsed dye laser (PDL) exerts favorable outcome in treatment of sulcus vocalis due to its therapeutic effects of collagen rearrangement and improved wound remodeling. In spite of the usefulness of PDL glottoplasty for treating sulcus vocalis, the device is no more available in the country. It prompted us to focus another angiolytic laser ; 532-nm KTP laser which has similar mechanisms of action and has been used for treatment of other laryngeal lesions elsewhere. Herein, we present a case of sulcus vocalis successfully treated with KTP laser. A patient underwent laryngomicrosurgery with angiolytic KTP laser (KTP glottoplasty) by the same surgical procedure with PDL glottoplasty. After the surgery, the patient presented improved voice outcome in time without complications.

Intense Pulsed Light and Q-Switched 1,064-nm Neodymium-Doped Yttrium Aluminum Garnet Laser Treatment for the Scarring Lesion of Discoid Lupus Erythematosus

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, and immunosuppressive agents. Topical tacrolimus and pimecrolimus have also been evaluated. Recent studies reported that several treatments, including pulsed dye laser, CO₂ laser, intense pulsed light (IPL), and 1,064-nm long-pulse neodymium-doped yttrium aluminum (Nd:YAG) have been used for the cosmetic treatment of DLE. Here, we report a case of a DLE scar that was successfully treated with a combination therapy of IPL and Q-switched 1,064-nm Nd:YAG laser.

Pulsed Dye Laser Treatment Combined with Oral Minocycline Reduces Recurrence Rate of Rosacea

BACKGROUND: The recurrence rate of rosacea was not known very well, but has been reported as 60% in 6 months after withdrawal of the drug. It is not known which treatment can reduce relapses of rosacea effectively. OBJECTIVE: The objective was to identify whether 595 nm-pulsed dye laser (PDL) treatment reduced recurrence rate among rosacea patients who were treated with oral minocycline. METHODS: One hundred and seven Korean patients with rosacea who started treatment with oral minocycline (100 mg/d) with or without PDL (2∼4 sessions) were evaluated retrospectively. The recurrence rate was estimated using the Kaplan-Meier method, and difference was evaluated using the log-rank test. Cox proportional hazards model was used to estimate hazard ratios and 95% confidence intervals (CIs) of risk factors for the recurrence of rosacea. RESULTS: The recurrence-free survival analysis revealed that the group with oral minocycline plus PDL was significantly different compared with the group with oral minocycline alone (p=0.011). Cox proportional hazards model showed that the combined use of PDL with oral minocycline appeared to be a significant protective factor for the hazard of recurrence of rosacea (hazard ratio, 0.492; 95% CI, 0.257∼0.941; p=0.032). CONCLUSION: PDL can be used added to oral minocycline to reduce relapses among rosacea patients who are undergoing oral minocycline treatment.

Two Cases of Secondary Sublesional Laryngeal Cyst after Pulsed Dye Laser Glottoplasty / 대한이비인후과학회지

The pulsed dye laser (PDL) has been shown to be effective for hypertrophic scars and keloids in dermatology initially. The fundamentals of PDL are based on photoacoustic, photothermal and photochemical effects. Because of noninvasive and physiologic features of PDL, it is recently used to treat vocal cord diseases. In particualr, treating sulcus vocalis with PDL (PDL glottoplasty) is a recently introduced surgical treatment. The sulcus vocalis irradiated with PDL can induce collagen synthesis and natural mucosal healing without adherent tissue injury. Although PDL glottoplasty is beneficial in the treatment of sulcus vocalis, we experienced two cases of secondary sublesional laryngeal cysts after PDL glottoplasty during long-term follow-up periods. There have been no reported cases of complication after PDL treatment for sulcus vocalis until now. Therefore, these two cases seem to be the first complication of PDL application reported in literature.

A Case of Acne Fulminans after Oral Isotretinoin Therapy / 대한피부과학회지

Acne fulminans (AF) is a rare severe form of acne associated with systemic symptoms. It primarily affects male adolescents and is clinically characterized by painful ulcerative nodules on the face, chest, and back. The associated systemic symptoms, such as fever, myalgia, and arthralgia, are usually present at the onset. The etiology of AF remains unknown, but there are many theories, such as increased androgens, autoimmune complex disease, and genetic predisposition. Treatment can be challenging because its response to traditional acne therapies is poor. A combination of oral steroids and isotretinoin is the most recommended treatment. Herein, we report a case of a 16-year-old Korean man with acne fulminans presenting with tender, hemorrhagic, crusted, inflammatory nodules on the upper chest, which occurred after isotretinoin use. After treatment with oral isotretinoin and pulsed dye laser for 23 weeks, most of the lesions healed leaving some scars.

Prospective Comparison of Dual Wavelength Long-Pulsed 755-nm Alexandrite/1,064-nm Neodymium:Yttrium-Aluminum-Garnet Laser versus 585-nm Pulsed Dye Laser Treatment for Rosacea

BACKGROUND: Rosacea treatments including oral/topical medications and laser therapy are numerous but unsatisfactory. OBJECTIVE: To compare the effectiveness of the dual wavelength long-pulsed 755-nm alexandrite/1,064-nm neodymium: yttrium-aluminum-garnet laser (LPAN) with that of 585-nm pulsed dye laser (PDL) for rosacea. METHODS: This was a randomized, single-blinded, comparative study. Full face received four consecutive monthly treatments with LPAN or PDL, followed-up for 6 months after the last treatment. Erythema index was measured by spectrophotometer, and digital photographs were evaluated by consultant dermatologists for physician's global assessment. Subjective satisfaction surveys and adverse effects were recorded. RESULTS: Forty-nine subjects with rosacea enrolled and 12 dropped out. There were no significant differences between LPAN and PDL in the mean reduction of the erythema index (p=0.812; 3.6% vs. 2.8%), improvement of physician's global assessment (p=1.000; 88.9% vs. 89.5%), and subject-rated treatment satisfaction (p=0.842; 77.8% vs. 84.2%). PDL showed more adverse effects including vesicles than LPAN (p=0.046; 26.3% vs. 0.0%). No other serious or permanent adverse events were observed in both treatments. CONCLUSION: Both LPAN and PDL may be effective and safe treatments for rosacea.

Incidental Ignition of a Pulsed Dye Laser Fiber During Laryngomicrosurgery: A Case Report

Surgical fires require an ignition source, oxidizer, and fuel. The pulsed dye laser (PDL) has been shown to be effective in the treatment of hypertrophic scars and keloids in dermatology. With the increasing number of applications of CO2, laser as ignition source has been associated with operating room fires in the otorhinolaryngologic field. There have been many case reports on PDL-induced fires in dermatology, but until now, there were no reports in the larynx. We describe a 57-year-old patient diagnosed with laryngeal hyperkeratosis treated by PDL-assisted laryngomicrosurgery. In this case, we experienced incidental PDL tip flaring during pulsed dye laser vaporization.

Surgical Excision Followed by Pulsed Dye Laser Sessions for the Successful Treatment of Glomangiomatosis on the Left Flank: A Case Report and Literature Review

Glomus tumors are benign neoplasms that are usually found in the subungual area, and are painful upon palpation. The typical treatment of choice is surgical excision. In rare cases, glomus tumors are observed as large-sized clusters, and are classified as atypical tumors known as glomangiomatosis. While surgical excision is the accepted standard of care, this proves difficult because of the tumors' large size and satellite lesions. We present the successful treatment of asymptomatic glomangiomatosis is situated on the left flank area by a combination of surgical excision and pulsed dye laser, which minimized the risk of scar formation.

Combined Treatment with Botulinum Toxin and 595-nm Pulsed Dye Laser for Traumatic Scarring

Traumatic scars on skin covering areas of high movement, especially areas on the face, can be stressful for patients. We report two cases of traumatic scars that occurred on the chin, and that were successfully treated with a combined therapy of 595-nm pulsed dye laser (PDL) and intramuscular injection of botulinum toxin. After the treatment, good cosmetic results were achieved in both patients. The only adverse effect during and after the treatments was mild pain, which resolved within several days without any additional treatment. In conclusion, the combination of 595-nm PDL and intramuscular botulinum toxin injection was shown to be a safe and effective treatment for traumatic scars on the mobile chin area in Korean patients.

Pigmentation after Intravenous Iron Injection Treated with 1064 nm Nd:YAG Laser and 595 nm Pulse Dye Laser / 대한피부과학회지

Ferric carboxymaltose is a non-dextran?iron complex used in patients with iron deficiency. However, iron injections may lead to long-lasting brown discoloration secondary to extravasation at the injection site. We herein report a case involving a patient who developed pigmentation after intravenous iron injection and was successfully treated with combined laser therapy. A 36-year-old woman presented with circumscript pigmentation on her left arm after having undergone intravenous iron injection for the treatment of iron deficiency anemia. Histopathologic examination revealed basal hypermelanosis and dermal infiltration of siderophages. Combined therapy with 1064 nm Nd:YAG laser and 595 nm pulsed dye laser was performed to treat the lesion, and marked improvement was noted after five sessions.

Nail Psoriasis Treated with 595 nm Pulsed Dye Laser / 대한피부과학회지

Nail psoriasis is a common finding in psoriatic patients and is associated with substantial adverse effects on the patient's quality of life. Although several treatment options are available, nail psoriasis tends to be persistent and refractory to therapy. Pulse dye laser (PDL) has been demonstrated to be effective for plaque-type psoriasis, but there are no reports on nail psoriasis being successfully treated with PDL in the Korean literature. We here report on a 46-year-old woman presenting with nail psoriasis recalcitrant to conventional treatment modalities, showing pitting, nail bed discoloration, and crumbling. We successfully treated the symptoms with 595 nm PDL, supporting the hypothesis that PDL may be a safe and effective therapeutic option in patients with recalcitrant nail psoriasis.
