Topical minoxidil 5% are effective in androgenetic alopecia (AGA). Spironolactone acts as an androgen antagonist by competitively blocking androgen receptors. Studying the effect of topical minoxidil 5% gel and spironolactone gel 1% in management of AGA. The study includes 60 patients diagnosed as AGA; (group I): treated with topical minoxidil gel 5%, (group II): with topical spironolactone gel 1% and group (III) treated with combined minoxidil 5% and spironolactone 1% gel. All patients were followed up monthly throughout the treatment period. Scalp biopsy was taken before and after 12 months. In group I, the clinical response was in 90% of patients with variable degrees in improvement, in group II, the clinical response was in 80% of patients, meanwhile, in group III the clinical response was in all patients (100%). Histopathological examination of skin biopsy after treatment revealed significant increase in anagen hair on the other hand, both telogen and vellus hair was significantly decreased meanwhile, the T/V ratio was significantly increased. The results of this work revealed that topical minoxidil gel 5% and topical spironolactone gel 1% were effective in treatment of AGA, while the combination of two agents was better in treatment.

Intralesional injection of bleomycin is an effective and safe treatment of plantar warts. Dermoscope is recommended in the evaluation of treatment success, as it can accurately tell if the wart needs further treatment, preventing premature stoppage of the treatment, thus decreasing the possibility of recurrences.

Many medications are available for scabies treatment including oral and topical ivermectin. However, studies comparing these two forms as a scabies treatment are few. This study compares efficacy and safety of topical versus oral ivermectin as scabies treatment. The study included 62 confirmed uncomplicated scabies patients, divided into: Group I (32 patients, received topical ivermectin) and Group II (30 patients, received oral ivermectin). Patients were assessed, clinically and by KOH smear at 1, 2 and 4 weeks. Treatment was repeated after one week in patients with persistent infection. Adverse events were recorded. Most patients (87.5% and 73.5% in group I and group II respectively) were symptom free after a single treatment. A second treatment was required in 4 patients of group I and 8 patients of group II. However, 2 weeks after treatment symptoms and signs completely resolved in all cases with no recurrence at 4 weeks. This study suggests that both topical and oral ivermectin are safe and equally effective in treatment of uncomplicated scabies. Single treatment, whether topical or oral, is associated with high cure rate in a week post treatment. However, repeating treatment after one week may be required to achieve 100% cure.

The present study suggests that one of the actions of PUVA therapy in psoriasis might be exerted through induction of apoptosis especially of lymphocytes by suppression of Bcl-2 expression and of keratinocytes through P53 and Fas pathways leading to healing of psoriasis.

The full exploration of the 'nutraceuticals' therapeutic potential in cosmetics has been hindered by their poor stratum corneum permeation. Therefore, the aim of the present study was to formulate a nutraceutical; quercetin, in novel vitamin C based nanovesicles (aspasomes), and to explore their beneficial effects in the treatment of acne. Aspasomes were characterized for their particle size, zeta potential, entrapment efficiency (EE%), 3-months storage stability, skin deposition/permeation, antioxidant potential, and morphology. Aspasomes antibacterial efficacy on Propionibacterium acnes using the zone of inhibition assay was also tested, whilst their safety on skin fibroblastic cells was assessed in vitro using 3T3 CCL92 cell lines. An exploratory clinical trial was conducted in acne patients, and the percentage reduction of inflammatory, noninflammatory and total acne lesions was taken as the evaluation criterion. Results revealed that quercetin-loaded aspasomes displayed a desirable nanometer size (125-184 nm), negative charge with good storage stability, and high skin deposition reaching 40%. Aspasomes managed to preserve the antioxidant activity of quercetin, and exhibited a significantly higher antibacterial effect (15 ± 1.53 mm) against Propionibacterium acnes than quercetin alone (8.25 ± 2.08 mm), and were safe on skin fibroblastic cells. Upon clinical examination in 20 acne patients (14 females, 6 males), quercetin aspasomes exhibited reduction percentages of 77.9%, 11.8% and 55.3% for inflammatory lesions, comedones and total lesions respectively. This opens vast applications of the presented formulation in the treatment of other oxidative skin diseases, and delineates the nutraceuticals and nanoformulations prepared from natural materials as promising dermatological treatment modes.

Background NB‐UVB has long been the vitiligo management pillar with capability of achieving the main treatment outcomes; repigmentation and stabilization. Its stabilizing effect in dark skin has been debatable. However, randomized controlled trials regarding NB‐UVB ability to control disease activity are lacking. Purpose To assess stabilizing effect of NB‐UVB in comparison to systemic corticosteroids, the mainstay in vitiligo stabilization, in skin photo‐types (III‐V). Methods This is a multicenter, placebo‐controlled, randomized, prospective study. Eighty patients with active nonsegmental vitiligo (NSV) (Vitiligo disease activity (VIDA) ≥2) were randomized to either NB‐UVB and placebo (NB‐placebo) or NB‐UVB and dexamethasone oral mini‐pulse (OMP) therapy (NB‐OMP) for 6 months. Sixty four patients completed the study, 34 in the NB‐OMP group and 30 in the NB‐placebo group. Patients were evaluated fortnightly according to presence or absence of symptoms/signs of activity. Results In spite of earlier control of disease activity observed in the NB‐OMP group, it was comparable in both groups by the end of the study period. Disease activity prior to therapy, but not extent, was found to influence control of activity in both groups. Thus, NB‐UVB is a safe sole therapeutic tool in vitiligo management. Not only does it efficiently achieve repigmentation, but also it is a comparable stabilizing tool for systemic corticosteroids in spite of slightly delayed control. Conclusion NB‐UVB is the only well‐established vitiligo therapy that can be used solely whenever corticosteroids are contraindicated or immune‐suppression is unjustified. Nonetheless, its combination with corticosteroids expedites response and improves compliance.
