Efficacy of combination therapy with efinaconazole 10% solution and 1064 nm Nd:YAG laser for treatment of toenail onychomycosis.

BACKGROUND: Onychomycosis is a common but difficult to treat nail disorder. Treatment strategies thus far have included oral and topical antifungals, surgical treatment and recently lasers have emerged as a therapeutic modality. OBJECTIVE: The objective of this study was to assess whether efinaconazole together with laser would result in greater clinical and mycologic cure and lower rate of relapse compared to efinaconazole alone. METHODS: Thirty subjects were randomized to either self-apply efinaconazole 10% once daily for 48 weeks, or follow the same treatment plan but also receive six treatments with a 1064 nm Nd: YAG laser every 4 weeks. The primary endpoint was to assess the proportion of subjects who achieved complete cure at week 52. RESULTS: The combination therapy group showed significantly quicker mycological cure at the 48- and 52-week follow-up. CONCLUSION: Both efinaconazole and combination with laser were efficacious treatment, but the combination therapy leads to quicker resolution with fewer rate of relapse.

Electrosurgical debulking of pretibial myxedema of the foot.

Pretibial myxedema or thyroid dermopathy constitutes dermal deposition of mucin, primarily hyaluronic acid and chondroitin sulfate. It is a manifestation of autoimmune thyroiditis, seen more in Graves disease than in Hashimoto thyroiditis. The time delay from treatment of hyperthyroidism to appearance of localized myxedema varies from one month to 16 years (mean 5.13 years). Despite a variety of therapeutic options, failure and relapse rates are high. Therapeutic options reported in the literature include compression, topical and intralesional corticosteroids, oral pentoxifylline, octreotide, rituximab, plasmapheresis, and high-dose intravenous immunoglobulin. We share our experience in two patients who were treated with electrosurgical debulking of selected longstanding myxedematous lesions, with one positive result and one negative result.

Pulsed Dye Laser Therapy in the Treatment of Warts: A Review of the Literature.

BACKGROUND: Warts or verrucae vulgaris are common cutaneous infections with currently no definitive curative treatments available. OBJECTIVE: To determine the efficacy of pulsed dye laser (PDL) in the treatment of warts. MATERIALS AND METHODS: A literature search was performed using the PubMed and MEDLINE databases. A search using {(Wart[s], verruca or condylomata)} AND [(Pulsed dye laser)] was used. Forty-four articles were identified as relevant to this review. RESULTS: Simple warts were very responsive to PDL, being treated successfully in over 95% of patients. Facial and anogenital warts also demonstrated excellent outcomes. Recalcitrant warts, displayed significant variability in their response, ranging between 50% and 100% across all articles. The response rates seen in peripheral warts (involving the hands and feet) were also very variable, ranging between 48% and 95%. Recurrence rates at 4 months of follow-up were documented as 0% to 15%. Complications have been described as very few and rare, the main ones being topical discomfort and erythema. CONCLUSION: Pulsed dye laser is a safe and effective modality in the treatment of warts that can be applied to most body parts. Cost and availability remain a limitation to the use of PDL; however, this modality can be used when other more traditional and accessible treatments have failed.

Use of a punch tool for paring plantar warts in an "awl-like" manner.

Paring is useful for both diagnosis and treatment of plantar warts. Paring techniques generally involve scalpel blades, abrasive tools, or curettes. However, these tools do not permit the use of an "awl-like" carving technique of the wart afforded by using a punch biopsy tool. We have found this technique to be associated with greater precision and safety, as well as potentially increased efficacy compared to traditional methods.

A pedunculated lesion on the foot: acquired fibrokeratoma.

Acquired fibrokeratomas are benign and uncommon lesions consisting of collagenous papules and nodules covered by hyperkeratotic epidermis. These tumors occur mainly on the fingers and toes and infrequently on the palms and soles. They may possibly be triggered by a reaction to a trauma and presents as small and solitary dome-shaped lesions with a collarete of slightly raised skin at the base. Several case reports have been published of this rare lesion, with only a few investigators describing lesions of the feet.

Evaluation of Nd:YAG laser device efficacy on onychomycosis: a case series of 30 patients.

Until recently, pharmacologic molecules have been the only available treatments for onychomycosis. Laser treatments were introduced for recurrent or resistant cases or in patients in whom oral treatments are contra-indicated. Some devices were approved by the Food and Drug Administration (FDA). Neodymium yttrium aluminium garnet (Nd:YAG) is used for onychomycosis as a short-pulse or a long-pulse system. We aim to evaluate the efficacy of the short-pulse Nd:YAG in treating onychomycosis, its side effects, cure rates, and 12-month recurrence rates. Efficacy was evaluated based on a subjective measure of patient satisfaction on a scale from 1 to 10, and an objective measure based on the results of the mycologic cultures. Medical records of 30 patients were reviewed. Ages ranged from 22 to 85, with a mean of 44. Mycologic cure at 12 months was not achieved in 5 patients (16.67%) who had received laser treatment. None of these patients showed any signs of clinical improvement. Twenty patients (66.67%) were completely cured at 12 months, with corroborating negative mycologic cultures. The remaining five patients (16.67%) had discordance between their clinical cure status and their mycologic cultures. Side effects were reported by 7 patients out of 30 (33%): pain within 48 hours of the treatment session, burning sensation in the treated nail bed area. Our primary end point of negative mycologic cultures at 12 months was seen in 24 out of 30 (80%) of our patients. Similar culture cure rates have not been reported before, not even with systemic treatments with oral antifungals. However, few limitations should warrant us (False-negative results in fungal cultures; time limitation; sample size…). Still, we propose that this alternative should be offered for patients in whom antifungals are contraindicated or for patients previously treated, but not cured by oral antifungals, and in elderly and polymedicated patients.

Quality of life after endoscopic lumbar sympathectomy for primary plantar hyperhidrosis.

BACKGROUND: Primary plantar hyperhidrosis is characterised by excessive secretion of the sweat glands of the feet and may lead to significant limitations in private and professional lifestyle. The aim of this prospective study was to assess the effect of endoscopic lumbar sympathectomy (ESL) on the quality of life (QL) of patients with primary plantar hyperhidrosis. METHODS: Bilateral ESL was performed on 52 patients, 31 men and 21 women with primary plantar hyperhidrosis. Perioperative morbidity and clinical results were evaluated in all patients after a mean follow-up of 15 months. Postoperative QL was examined with the SF-36V2 questionnaire and the hyperhidrosis-specific questionnaires devised by Milanez de Campos and Keller. RESULTS: All procedures were carried out endoscopically with no perioperative morbidity. Plantar hyperhidrosis was eliminated in 50 patients (96%) and two patients (4%) suffered a relapse. Unwanted side effects occurred in the form of compensatory sweating in 34 (65%) and in the form of postsympathectomy neuralgia in 19 patients (37%). Ninety six percentage of patients were satisfied with the postoperative result and 88% would have the surgery repeated. The SF-36V2 questionnaire revealed a significant improvement of QL after lumbar sympathectomy in physical health (physical component summary, p < 0.01) as well as mental health (mental component summary, p < 0.05). Improved QL was also demonstrated in the Milanez de Campos questionnaire in the dimensions functionality/social interactions (p < 0.01), intimacy (p < 0.01), emotionality (p < 0.01) and specific circumstances (p < 0.01) as well as in the Keller questionnaire in the area of plantar hyperhidrosis (p < 0.01). CONCLUSION: The performance of an ESL in patients with primary plantar hyperhidrosis leads to the effective elimination of excessive sweat secretion of the feet and to an increase in QL.

[Mycetoma of the foot: a case report]. / Mycétome actino-mycosique du pied, à propos d'un cas.

Mycetoma is a chronic inflammatory cutaneous and subcutaneous pathology caused by either a fongic (eumycetoma) or bacterial (actinomycetoma) infection, which lead to a granulomatous tumefaction with multiple sinuses. When localized in the foot this infection is named "Madura foot". This infection is endemic to tropical and subtropical regions and rarely occurs in western countries. A historical case in Europe of a foot mycetoma evolving since 20 years without any treatment is presented. A histopathologic diagnosis of actinomycetoma has been done in 1987. The patient presented a severe Staphylococcus aureus chronic osteitis leading to a trans-tibial amputation. This case allows to present this infection which, even if rarely presented in France, can be meet especially among a migrant's population.

Lack of efficacy with 1064-nm neodymium:yttrium-aluminum-garnet laser for the treatment of onychomycosis: a randomized, controlled trial.

BACKGROUND: Laser therapies have been Food and Drug Administration approved for temporary nail plate clearance; however, there is minimal evidence of their long-term efficacy. OBJECTIVE: We sought to evaluate the clinical and mycological clearance of toenails treated with 1064-nm neodymium:yttrium-aluminum-garnet laser versus no treatment. METHODS: This was a randomized, controlled, single-center trial comparing 2 treatments with 1064-nm neodymium:yttrium-aluminum-garnet laser (fluence of 5 J/cm(2), rate of 6 Hz) spaced 2 weeks apart versus no treatment in 27 patients (N = 125 affected nails) with clinical and mycological diagnosis of onychomycosis. At 3 months, patients were assessed with mycological cultures and proximal nail plate measurements. Patients treated with laser were also assessed with proximal nail plate measurements at 12 months. RESULTS: At 3 months, 33% of patients treated with laser achieved a negative mycological culture compared with 20% of the control group (P = .49), and had more proximal nail plate clearance compared with control subjects (0.44 vs 0.15 mm, P = .18), which was not statistically significant. At 12 months, there was no difference in nail plate clearance between laser versus control subjects (0.24 vs 0.15 mm, P = .59). LIMITATIONS: Our study was limited by the small sample size and number of treatments. CONCLUSIONS: There was no significant mycological culture or clinical nail plate clearance with 1064-nm neodymium:yttrium-aluminum-garnet laser compared with control.

Punch grafting of chronic ulcers in patients with laminin-332-deficient, non-Herlitz junctional epidermolysis bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is a genetic, heterogeneous, trauma-induced blistering disease. Patients with laminin-332-deficient non-Herlitz junctional EB (JEB-nH) can have impaired wound healing witnessed by persistent, small, deep ulcers on the hands and feet that adversely affect the quality of life. OBJECTIVE: We sought to present the results of punch grafting in patients with laminin-332-deficient JEB-nH, and to discuss its therapeutic value. METHODS: Retrospective analysis of the Dutch EB Registry revealed 4 patients with laminin-332-deficient JEB-nH who were treated with punch grafting. Punch grafting was performed according to protocol, and the patients were followed up. RESULTS: In the past 10 years we have treated 23 ulcers in 4 patients with JEB-nH using punch grafting without any complications or adverse effects. The ulcers had on average persisted 6 years before treatment. Healing rate after punch grafting was 70% (n = 16), with a mean healing time of 2 months. Thirty percent (n = 7) of the treated ulcers did not completely heal, but did show improvement. The recurrence rate after 3 months was 13% (n = 2), and was a result of renewed blistering. LIMITATIONS: Limitations of the study are the retrospective design, small number of patients, absence of a control group, and follow-up and ulcer measurement that were not standardized. CONCLUSIONS: Punch grafting can be used as a first-line treatment in small persistent ulcers in patients with JEB-nH. The method is easy, is inexpensive, has little risk of complications, and results in significant healing rates and improvement in quality of life.

Hair-thread tourniquet syndrome: a hidden hazard.

Hair-thread tourniquet syndrome (HTTS) is a rare disorder characterized by the encircling of an appendage by a hair or thread. We report an 8-month-old boy with toe HTTS. Early recognition is required to avoid the serious consequences of its delayed diagnosis.

Long-term efficacy of radiofrequency ablation in treatment of common and palmo-plantar warts.

Current treatments for warts induce significant local tissue damage and do not prevent recurrence. We evaluated the efficacy of localised radiofrequency heat (RFH) therapy in inducing the long-term resolution of common and palmo-plantar warts in a placebo-controlled randomised single blind trial. Our data show that RFH therapy is a safe, cosmetically acceptable and long-term effective treatment for warts.

Treating onychomycoses of the toenail: clinical efficacy of the sub-millisecond 1,064 nm Nd: YAG laser using a 5 mm spot diameter.

BACKGROUND: Onychomycosis is a relatively common fungal infection. Current treatments have limited applicability and low cure rates. Recently introduced laser therapy has shown to be a safe and effective treatment for onychomycosis. In this study, we evaluate a submillisecond Nd:YAG 1,064 nm laser for treating onychomycoses of the tonail. METHODS: Thirteen subjects (9 female, 4 male) with 37 affected toenails received 1 to 3 treatments 4 and/or 8 weeks apart with a sub-millisecond 1,064 nm Nd:YAG laser. Diagnosis of onychomycosis was confirmed with microscopy. Average follow-up time was 16 weeks post-final treatment. Photos were taken and degree of turbidity was determined using a turbidity scale (ranging from "0 = clear nail" to "10 = completely turbid nail") at each visit. Improvement in turbidity was determined by comparison of turbidity scores at baseline and 16-week follow-up on average. Efficacy was assessed by an overall improvement scale (0 to 4), which combined improvement in turbidity scores and microscopic examination. Overall improvement was classified as "4 = complete clearance" if the turbidity score indicated "0 = clear nail" accompanied by a negative microscopic result. No microscopic examination was performed unless the turbidity score showed "0 = clear nail." RESULTS: Treatments were well tolerated by all subjects and there were no adverse events. Of the 37 toenails treated, 30 (81%) had "moderate" to "complete" clearance average of 16 weeks post-final treatment. Nineteen toenails (51%) were completely clear and all tested negative for fungal infection on direct microscopic analysis. Seven (19%) toenails had significant clearance and four (11%) had moderate clearance. CONCLUSIONS: The preliminary results of this study show this treatment modality is safe and effective for the treatment of onychomycosis in the short term. Additional studies are needed to more fully assess the clinical and mycological benefits as well as optimize the treatment protocol and parameters.

308-nm Excimer laser treatment of palmoplantar psoriasis.

Psoriasis is a chronic inflammatory condition affecting 1-3% of the population. The incidence of palmoplantar involvement has been estimated to be between 2.8% and 40.9%. Significant psychosocial distress and difficulty performing activities of daily living can result. Treatment is often challenging. Traditional treatments include topical steroids, anthralin, calcipotriene, PUVA, methotrexate, cyclosporine, retinoids and biologics. In this case series, we report our success with the 308-nm excimer laser in the treatment of palmoplantar psoriasis.

Application of dermal regenerative template in reconstructing skin defects after plantar malignant melanoma excision.

PURPOSE: The excision of plantar malignant melanoma frequently leads to wide skin defects on the plantar surface. This study aimed to investigate the advantages and feasibility of dermal regenerative template reconstructing plantar blemishes caused by malignant melanoma. METHODS: 28 patients identified with plantar malignant melanoma were included in this retrospective article. Eighteen patients received immediate skin grafts after wide excision skin graft (SG) group), whereas the remaining 10 patients were treated with dermal regenerative template (DRT) (Lando ®, Shenzhen TsingCare Medical Co. Ltd) 14 days before skin grafts (DRT group) and the postoperative survival rate in the two groups was analyzed. During the 6-month follow-up, we compared the scar index, plantar pain, and recurrent skin graft ulcer incidence on the skin grafts area. RESULTS: Postoperative survival rate in the DRT group (91.75% ± 7.64%) was higher than in the SG group (80.51% ± 7.17%). The DRT group showed less scar formation on Vancouver scar scale (VSS index): 3.40 ± 1.07 than the SG group (VSS index: 6.33 ± 0.68). The dermal regenerative template alleviated plantar pain and decreased the incidence of ulcer on the skin grafts area. CONCLUSIONS: The dermal regenerative template not only improves the survival rate of skin grafts but also alleviates scar condition, plantar pain and recurrent skin graft ulcer. This study provides a new reconstructive strategy in plantar skin defects after the excision of malignant melanoma.
