We have determined the depth and duration of analgesia to needle insertion after topical application of EMLA cream (Eutectic Mixture of Local Analgesics). EMLA was applied for 30, 60, 90 and 120 min and the sensory and pain threshold depths were determined before analgesia (1.0 and 1.9 mm, respectively) and up to 4 h after the cream was removed from the skin. The maximal depth of analgesia (app...

OBJECTIVE To review the evidence regarding the treatment and prevention of herpes labialis. QUALITY OF EVIDENCE The evidence relating to treatment and prevention of herpes labialis is derived from randomized controlled trials (level I evidence). MAIN MESSAGE Treatment with an indifferent cream (zinc oxide or zinc sulfate), an anesthetic cream, or an antiviral cream has a small favourable ef...

in order to improve local therapeutic techniques for the massively burnt patients and to minimize the pain associated with dressing change, the concept of topical film was utilized to formulate a topical antimicrobial spray. the commonly used topical antimicrobial silver sulfadiazine spray was formulated as a new drug delivery system. the release of therapeutic agents in vitro from medicated sp...

OBJECTIVES To evaluate histological alterations in prepuce of patients with phimosis submitted to topic treatment with betamethasone in association with hyaluronidase. MATERIALS AND METHODS We studied sixty patients (mean age 4.5), presenting true phimosis and treated with a topical treatment with betamethasone cream (0.2%) + hyaluronidase. The parents of seven of these patients opted for cir...

BACKGROUND Permethrin, a pyrethroid insecticide, is not yet available in Iran and may be a useful substitute for the control of scabies in Iran. AIM To compare the efficacy of topical lindane with topical permethrin in the treatment of scabies in a population in Iran. METHODS In a double-blind, randomized study, all consecutive patients with scabies were randomized into two groups. One grou...

Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei va. hominis). It is commonly treated with topical insecticides, but the treatment of choice is still controversial. The aim of this study is to compare the efficacy of topical ivermectin vs. permethrin 2.5% cream for the treatment of scabies. In total, 380 patients with scabies were enrolled, and ran...

A topical o/w cream containing tretinoin microspheres was prepared. Gelatin microspheres of tretinoin were prepared using coacervation method. These microspheres contained about 50% w/w tretinoin. The particle size range of microspheres was between 90-150 m m. In vitro drug release from microspheres and a cream formulation was studied. It was shown that drug release from microspheres followed H...

Purpose of this study was to establish a lecithin nanoemulsion (LNE) without any synthetic surfactant as a topical delivery vehicle and to evaluate its topical delivery potential by the following factors: particle size, morphology, viscosity, stability, skin hydration and skin penetration. Experimental results demonstrated that an increasing concentration of soybean lecithin and glycerol result...

BACKGROUND Imiquimod, a synthetic Toll-like receptor 7 agonist enhanced immunogenicity of influenza vaccine in a mouse model. We hypothesized that topical imiquimod before intradermal influenza vaccination (TIV) would produce similar effect in human. METHODS We performed a prospective 1-year follow-up, double-blind, randomized, controlled trial with adults with comorbidities. Participants wer...
