Background Treatment of vascular skin diseases is one of the most important indications of the laser. Aims To evaluate the effectiveness of 577‐nm pro‐yellow laser in the treatment of some vascular skin diseases. Patients/methods Ninety‐five patients with vascular skin diseases were included in this prospective monocentric study. They were classified into: port‐wine stain birthmarks (n = 37), papulopustular rosacea (n = 20), facial telangiectasia (n = 16), and facial erythema (n = 22). All participants received a monthly session of 577‐nm pro‐yellow laser. Follow‐up was done by comparing the photographs before and at every follow‐up visit. Results At the final visit, there was a significant improvement (>50%) occurred in 24/37 (64.82%), 12/20 (60%), 10/16 (62.5%), and 19/22 (86.3%) cases and poor response occurred in 6/37 (16.2%), 2/20 (10%), 2/16 (12.5%), and 0/22 cases after a mean number of sessions 7.76 ± 2.28, 3.1 ± 1.8, 3.63 ± 1.12, and 1.8 ± 0.85 in port‐wine stain, rosacea‐, facial telangiectasia‐, and facial erythema‐treated groups, respectively. Transient irritation and erythema during the session were the only complications reported in the study. Conclusion Facial port‐wine stains, rosacea, telangiectasia, and erythema can be successfully treated with a single pass of 577‐nm pro‐yellow laser with a minimal side effect. Facial erythema showed the highest degree of success with the least number of sessions, while more sessions needed for the treatment of port‐wine stain.

Objective. To investigate the clinical efficacy and safety of intralesional injection of 2% zinc sulfate solution in the treatment of common warts. Patients and Methods. One hundred and twenty patients (78 females and 42 males) aged 5–55 years with 225 common warts participated in this prospective monocentric randomized study. All lesions were treated with intralesional injection of 2% zinc sulfate. Results. From 225 warts injected, 135 warts (60%) cured from the first session, 51 warts (22.67%) cured from the second session, and 12 warts (5.33%) cured from the third session. There is no significant relation between improvement and patient's ages, duration, or number of warts (P > 0.05). All patients complained from pain during injection, and all treated lesions showed redness, tenderness, and swelling in the first 3 days after injection. Late complications were postinflammatory hyperpigmentation in 90 patients (75%), scaring in 9 patients (7.5%), and ulceration in 3 patients (2.5%). Recurrence occurred in 3 lesions (1.33%). Conclusion. The clinical data indicate that intralesional injection of 2% zinc sulfate is an effective maneuver in the treatment of common warts; however, its associated complications limit its use.

Punch grafting is more effective than follicular grafting in the treatment of stable vitiligo; however, follicular hair transplantation is cosmetically better, so we recommend it in exposed areas as face.

Photodynamic therapy (PDT) can be defined as the administration of a nontoxic drug or dye known as Photosensitizer (PS) either systemically, locally, or topically to a patient bearing a lesion. Methylene blue considered as a photosensitizer for photodynamic therapy. Current topical and oral therapies for acne vulgaris have limited efficacy, especially in moderate to severe cases, In view of this, the aim of our study was to use methylene blue in the form of niosomal hydrogel for photodynamic treatment of acne. To reach this objective we studied the following aspects; formulation of MB blue in different niosomal preparation, characterization of methylene blue niosomes, Span 60 transition temperatures, In vitro release study, kinetic analysis of the release data, factors affecting the encapsulation of methylene blue in niosomes via effect of: amount of drug, cholesterol: span 60 ratios, and stabilizers. The results revealed that, niosomes were successfully produced by reversed phase evaporation technique using different ratio of cholesterol: span 60.The most favorable amount of MB could be used in niosomal preparation was 1000µg. The best fit kinetic favored Higuchi diffusion mechanism. The incorporation of MB niosomes in HPMC 3% gel resulted in feasible release rate of MB. The data obtained served as the basis to reach a secondary objective which is clinical evaluation of selected niosomal gel of methylene blue for photodynamic treatment of acne which showed higher significant improvement in inflammation when compared with IPL treatment.

One thousand and sixty-four-nm Nd:YAG laser is an effective and safe method in the reduction of unwanted facial hair. Trichoscan is an easy and more accurate method in monitoring the treatment of hair disorders.
