Novel emerging therapy for erectile dysfunction: efficacy and safety of flat magnetic stimulation.

BACKGROUND: The erectile dysfunction (ED), which is the inability to achieve and/or sustain a penile erection sufficient to result in a satisfying sexual performance, represents a very common complaint. for men over forty years old. The aim of the study was to evaluate if Flat Magnetic Stimulation (FMS) technology could help individuals with symptomatic erectile dysfunction. METHODS: Twenty patients with erectile dysfunction, underwent eight sessions of about 30 minutes each in a twice a week frequency with the study device. During treatments, every potential side effect was assessed. The International Index of Erectile Function (IIEF) was compiled by all patients at the beginning, after the eighth treatment and at 1 month from the end of the last treatment. The questionnaire scores were presented as median values along with the interquartile range (IQR) and we set the significance threshold at 0.01. RESULTS: After the treatment and at 1-month follow-up, the increase in questionnaire scores was statistically significant compared to the baseline, thus supporting the clinical usefulness of this treatment. In particular, the result of the study indicates a statistically significant difference between IIEF score before treatment (Median = 34) and IIEF score after the end of treatment (Median = 45) and between IIEF score before treatment and IIEF score at 1-month follow-up (Median = 54). CONCLUSIONS: The study findings showed that FMS represents a promising treatment option to individuals affected by symptomatic erectile dysfunction.

Fractional CO2 Laser Therapy for Effective Treatment of Facial Traumatic Hypertrophic Scar: A Case Report.

BACKGROUND Hypertrophic scars occur when there is an excessive wound-healing response in the skin. Fractional, or fractionated, carbon dioxide (CO2) laser therapy uses narrow shafts of light to smooth the skin surface and stimulate dermal collagen, which tightens the skin. This case report describes a 57-year-old woman with a traumatic hypertrophic scar of the face treated with fractional carbon dioxide laser therapy. The purpose of this case report was to highlight the role of fractional CO2 laser therapy in treatment of a facial traumatic hypertrophic scar in a patient after a motor vehicle crash. CASE REPORT A 57-year-old female patient presented with a hypertrophic, rigid, post-traumatic scar on the left side of her face following a motor vehicle crash. For the hypertrophic scar removal, the patient underwent 1 treatment session with fractional CO2 laser using the µ-Scan DOT scanning system. After 1 laser treatment session, the photographic documentation, which permits monitoring the treatment's effectiveness in esthetic improvement, showed a significant improvement in scar texture and color. In addition, a significant reduction in scar height was observed following laser therapy. Fractional laser treatment with the device was very well tolerated by the patient, who reported no pain or discomfort, complications, or adverse effects either during treatment or in the follow-up period (3 months). CONCLUSIONS This report demonstrates the cosmetic application of fractional carbon dioxide laser therapy in a case of hypertrophic scar with the use of an effective therapeutic protocol that did not require the use of suturing.

BACKGROUND: Studies on pulsed dye laser (PDL) have shown the best efficacy and safety data for treating vascular anomalies among the various lasers used and the 595-nm PDL has been used to treat cutaneous vascular anomalies for about 30 years. The purpose of this study was to assess the efficacy of 595 nm Pulsed Dye Laser in the management of facial flat angiomas present in the form of Port-Wine Stain. MATERIALS AND METHODS: Seven cases of PWS in Fitzpatrick skin type ranged from I to III and colour ranging from pink to purple, were treated with 595 nm pulse Dye Laser. Patients underwent to 6-8 laser sessions at 20-30 days intervals. Results obtained were judged by dermatologist, by comparing pre-treatment and post-treatment photographs, 6 months after the last session and a quartile scale of lesion clearance (4-point Investigator Global Assessment scale): 1 = no or low results (0%-25% of the lesion area improved), 2 = slight improvement (25%-50% of the lesion area cleared), 3 = moderate-good improvement (50%-75%), and 4 = excellent improvement (75%-100%) was used. Possible side effects such as blisters, hyper/hypopigmentation, and scarring were monitored. RESULTS: All patients observed global improvements. 71% of patients achieved excellent clearance and 29% patients achieved good-moderate clearance of their angioma. Patients were asked for a subjective evaluation of the results: 57% of patients were very satisfied, 29% were satisfied, and 14% patients were not very satisfied with the results. No patients were dissatisfied. No significant side effects were noted. CONCLUSION: This research confirms the efficacy of the 595 nm PDL for flat angioma management, without considerable side effects.

Clinical evidence of 595 nm pulse dye laser treatment for viral warts on hands and feet.

BACKGROUND: Viral warts, induced by infection by different HPV genotypes, are highly frequent in the general population, particularly during infancy and among adolescents. The effectiveness of the 595 nm Pulse dye-laser in treating viral warts on the hands and feet in both adults and children was investigated in this study. MATERIALS AND METHODS: A selection of 203 patients with multiple viral warts was made. All patients underwent 4-5 treatment sessions with a 595 nm pulse Dye Laser (PDL). Treatment outcome was assessed by a quartile scale: 1 indicates no or low results (0%-25% of the lesion area cleared), 2 indicates slight clearance (25%-50% of the lesion area cleared), 3 indicates moderate-good clearance (50%-75%), and 4 indicates excellent clearance (75%-100%). Patients were asked for a subjective evaluation of the perceived overall results by means of the following score: unsatisfied (1), not very satisfied (2), satisfied (3), and very satisfied (4). Possible side effects were monitored. Results obtained were judged with a photographic evaluation, immediately and at the control visit (6 months after the last laser session). RESULTS: All patients observed global improvements. Most of the lesions were completely removed after laser therapy. A total of 95% of patients achieved excellent clearance and they were very satisfied following the laser treatment. Relevant side effects were absent in all patients. CONCLUSION: PDL treatment with the study device using a wavelength of 595 nm has proven to be a tolerable and safe therapy for viral warts management.

The 675-nm wavelength for treating facial melasma.

BACKGROUND: Melasma is an acquired skin problem. It characterises sun-exposed areas, particularly on the face, with irregular borders and bilateral distribution. With this study, we want to strengthen the scientific literature regarding the use of a 675-nm laser device for the treatment of women and men with facial melasma pigmentary and vascular symptoms. MATERIALS AND METHODS: Eighteen patients were treated for facial melasma. A total of three sessions at 30-day intervals were performed with a 675-nm laser device. A five-point Global Aesthetic Improvement Scale was used to separately assess the improvement of the patient's skin 3 months after the last treatment (T1) compared to baseline (T0). The pain during treatment was measured using a Visual Analog Scale of 10 points. The non-ablative laser system used emits red light with a wavelength of 675 nm through a 13 × 13 mm scanning system. RESULTS: At T1 , a consistent improvement in the pigmentary and vascular components was visible. This is always combined with a considerable reduction in vascular expression. CONCLUSION: Our research shows that individuals with Fitzpatrick phototypes II to III can treat facial melasma with the 675-nm laser source system without risk. Due to its interaction with melanin, collagen and haemoglobin chromophores, as well as its excellent capacity to penetrate tissues with less heating, this system is promising in the treatment of pigmentary and vascular illnesses such as melasma. The great success of the technology we used came from the reduced levels of inflammation produced after the treatments and the low energy level implied.

Efficacy and Safety of Carbon Dioxide Laser System in the Treatment of Scalp Sebaceous Adenoma With the Use of a New Scanner Unit.

Sebaceous adenoma (SA) is a rare solitary tumor that preferentially affects the forehead and scalp. The objective of this case report was to determine the efficacy and safety of a 10,600-nm carbon dioxide (CO2) laser device in the treatment of large scalp SA, using a new scanning system which allows to speed up the removal of the lesion. A 65-year-old male with SA on the scalp area underwent one session with the CO2 laser system. For this procedure, a new scanner system with 7-inch or 4-inch focal handpieces were used. A local anesthesia with lidocaine was performed before laser treatment. Some possible side effects such as dyschromia, burning sensation, bleeding and mild to moderate post-treatment erythema, itching, crusting, and edema, were checked. In order to monitor the effectiveness of the treatment, clinical photos that documented the patient lesion were captured before treatment and at 1 month of follow-up. The clinical and aesthetic results observed after laser procedure were excellent, with a complete remission of patient's scalp SA lesion at 4 weeks' follow-up. Patient satisfaction was very high, and no side effects were observed. This laser system technology allows for precise, effective, and targeted action on the lesions treated while simultaneously protecting the surrounding areas, ensuring the best possible re-epithelialization.
