    The highly skewed distribution of species among genera, although challenging to macroevolutionists, provides an opportunity to understand the dynamics of diversification, including species formation, extinction, and morphological evolution. Early models were based on either the work by Yule [Yule GU (1925) Philos Trans R Soc Lond B Biol Sci 213:21-87], which neglects extinction, or a simple birth-death (speciation-extinction) process. Here, we extend the more recent development of a generic, neutral speciation-extinction (of species)-origination (of genera; SEO) model for macroevolutionary dynamics of taxon diversification. Simulations show that deviations from the homogeneity assumptions in the model can be detected in species-per-genus distributions. The SEO model fits observed species-per-genus distributions well for class-to-kingdom-sized taxonomic groups. The model's predictions for the appearance times (the time of the first existing species) of the taxonomic groups also approximately match estimates based on molecular inference and fossil records. Unlike estimates based on analyses of phylogenetic reconstruction, fitted extinction rates for large clades are close to speciation rates, consistent with high rates of species turnover and the relatively slow change in diversity observed in the fossil record. Finally, the SEO model generally supports the consistency of generic boundaries based on morphological differences between species and provides a comparator for rates of lineage splitting and morphological evolution.

    This article reviews topical management strategies for degenerative osteoarthritis (OA) of the knee. A search of Pubmed, Embase and the Cochrane library using MeSH terms including "topical," "treatment," "knee" and "osteoarthritis" was carried out. Original research and review articles on the effectiveness and safety, recommendations from international published guidelines and acceptability studies of topical preparations were included. Current topical treatments included for the management of knee OA include topical nonsteroidal anti-inflammatory drugs, capsaicin, salicylates and physical treatments such as hot or cold therapy. Current treatment guidelines recommend topical nonsteroidal anti-inflammatory drugs as an alternative and even first-line therapy for OA management, especially among elderly patients. Guidelines on other topical treatments vary, from recommendations against their use, to in favor as alternative or simultaneous therapy, especially for patients with contraindications to other analgesics. Although often well-tolerated and preferred by many patients, clinical care still lags in the adoption of topical treatments. Aspects of efficacy, safety and patient quality of life data require further research. Copyright © 2018 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

    Diet is commonly assumed to affect the evolution of species, but few studies have directly tested its effect at macroevolutionary scales. Here we use Bayesian models of trait-dependent diversification and a comprehensive dietary database of all birds worldwide to assess speciation and extinction dynamics of avian dietary guilds (carnivores, frugivores, granivores, herbivores, insectivores, nectarivores, omnivores and piscivores). Our results suggest that omnivory is associated with higher extinction rates and lower speciation rates than other guilds, and that overall net diversification is negative. Trait-dependent models, dietary similarity and network analyses show that transitions into omnivory occur at higher rates than into any other guild. We suggest that omnivory acts as macroevolutionary sink, where its ephemeral nature is retrieved through transitions from other guilds rather than from omnivore speciation. We propose that these dynamics result from competition within and among dietary guilds, influenced by the deep-time availability and predictability of food resources.

    The evolution of quantitative characters over long timescales is often studied using stochastic diffusion models. The current toolbox available to students of macroevolution is however limited to two main models: Brownian motion and the Ornstein-Uhlenbeck process, plus some of their extensions. Here, we present a very general model for inferring the dynamics of quantitative characters evolving under both random diffusion and deterministic forces of any possible shape and strength, which can accommodate interesting evolutionary scenarios like directional trends, disruptive selection, or macroevolutionary landscapes with multiple peaks. This model is based on a general partial differential equation widely used in statistical mechanics: the Fokker-Planck equation, also known in population genetics as the Kolmogorov forward equation. We thus call the model FPK, for Fokker-Planck-Kolmogorov. We first explain how this model can be used to describe macroevolutionary landscapes over which quantitative traits evolve and, more importantly, we detail how it can be fitted to empirical data. Using simulations, we show that the model has good behavior both in terms of discrimination from alternative models and in terms of parameter inference. We provide R code to fit the model to empirical data using either maximum-likelihood or Bayesian estimation, and illustrate the use of this code with two empirical examples of body mass evolution in mammals. FPK should greatly expand the set of macroevolutionary scenarios that can be studied since it opens the way to estimating macroevolutionary landscapes of any conceivable shape.

    1986-01-01

    A randomised, double blind, single dose study of topical haloperidol, a dopamine receptor blocking drug, was performed on 20 healthy volunteers. After its administration a modest reduction in intraocular pressure was recorded over the six-hour study period, but the difference was not significant at the p less than 0.05 level. Although dopamine blocking agents are effective in reducing intraocular pressure in experimental animals, topical haloperidol appears unlikely to be clinically useful in...

    Honey is a viscous, supersaturated sugar solution derived from nectar gathered and modified by the honeybee, Apis mellifera. Honey has been used since ancient times as a remedy in wound care. Evidence from animal studies and some trials has suggested that honey may accelerate wound healing. The objective of this review was to assess the effects of honey compared with alternative wound dressings and topical treatments on the of healing of acute (e.g. burns, lacerations) and/or chronic (e.g. venous ulcers) wounds. For this update of the review we searched the Cochrane Wounds Group Specialised Register (searched 15 October 2014); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 9); Ovid MEDLINE (1946 to October Week 1 2014); Ovid MEDLINE (In-Process & Other Non-Indexed Citations 13 October 2014); Ovid EMBASE (1974 to 13 October 2014); and EBSCO CINAHL (1982 to 15 October 2014). Randomised and quasi-randomised trials that evaluated honey as a treatment for any sort of acute or chronic wound were sought. There was no restriction in terms of source, date of publication or language. Wound healing was the primary endpoint. Data from eligible trials were extracted and summarised by one review author, using a data extraction sheet, and independently verified by a second review author. All data have been subsequently checked by two more authors. We identified 26 eligible trials (total of 3011 participants). Three trials evaluated the effects of honey in minor acute wounds, 11 trials evaluated honey in burns, 10 trials recruited people with different chronic wounds including two in people with venous leg ulcers, two trials in people with diabetic foot ulcers and single trials in infected post-operative wounds, pressure injuries, cutaneous Leishmaniasis and Fournier's gangrene. Two trials recruited a mixed population of people with acute and chronic wounds. The quality of the evidence varied between different comparisons and

    During the production of oil and gas, large amounts of water are brought to the surface and must be disposed of in an environmentally sensitive manner. This is an especially difficult problem in offshore production facilities where space is a major constraint. The chief regulatory criterion for produced water is oil and grease. Most facilities have little trouble meeting this criterion using conventional oil-water separation technologies. However, some operations have significant amounts of naphthenic acids in the water that behave as oil and grease but are not well removed by conventional technologies. Aerobic biological treatment of naphthenic acids in simulated-produced water has been demonstrated by others; however, the system was easily overloaded by the large amounts of low-molecular-weight organic acids often found in produced waters. The objective of this research was to determine the ability of an anaerobic biological system to treat these organic acids in a simulated produced water and to examine the potential for biodegradation of the naphthenic acids in the anaerobic environment. A small fixed-film anaerobic biological reactor was constructed and adapted to treat a simulated produced water. The bioreactor was tubular, with a low-density porous glass packing material. The inocula to the reactor was sediment from a produced-water holding pond from a municipal anaerobic digester and two salt-loving methanogenic bacteria. During start-up, the feed to the reactor contained glucose as well as typical produced-water components. When glucose was used, rapid gas production was observed. However, when glucose was eliminated and the major organic component was acetate, little gas was generated. Methane production from acetate may have been inhibited by the high salt concentrations, by sulfide, or because of the lack, despite seeding, of microbes capable of converting acetate to methane. Toluene, a minor component of the produced water (0.1 g/L) was removed in the

    2010-12-01

    Osteoarthritis (OA), the most common form of arthritis, often affects hands, hips, and knees and involves an estimated 26.9 million US adults. Women have a higher prevalence of OA, and the risk of developing OA increases with age, obesity, and joint malalignment. OA typically presents with pain and reduced function. Therapeutic programs are often multimodal and must take into account pharmaceutical toxicities and patient comorbidities. For example, nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with cardiovascular, gastrointestinal, and renal adverse events. Topical NSAIDs offer efficacy with reduced systemic drug exposure. This is a review of current guideline recommendations regarding the use of topical NSAIDs in OA of the hand and knee. Articles were identified by PubMed search (January 1, 2000 to May 21, 2010). Several current guidelines for management of OA recommend topical NSAIDs, indicating them as a safe and effective treatment. One guideline recommends that topical NSAIDs be considered as first-line pharmacologic therapy. A US guideline for knee OA recommends topical NSAIDs in older patients and in patients with increased gastrointestinal risk. The consensus across US and European OA guidelines is that topical NSAIDs are a safe and effective treatment for OA. Because the research base on topical NSAIDs for OA is small, guidelines will continue to evolve.

  18. Principles of topical treatment: advancement in gel vehicle technology.

    2014-04-01

    Topical treatment is a pillar of dermatologic practice. The delivery of drug by a topical vehicle is dependent on complex physical chemistry and on how well patients apply the product. The potency of topical agents is not solely dependent on the concentration of active drug in the vehicle. A corticosteroid molecule may have vastly different potency depending on what vehicle is used to deliver it. Similarly, a new gel vehicle is able to deliver considerably more active antifungal than an older vehicle technology and may represent a promising vehicle for other novel formulations. The use of new vehicles can provide more effective means for treating patients with skin disease.

  19. Topical ganciclovir in the treatment of acute herpetic keratitis.

    Tabbara, Khalid F; Al Balushi, Noorjehan

    2010-08-19

    Herpetic keratitis is caused by herpes simplex virus (HSV) and is a common cause of corneal blindness. Following a primary ocular herpetic infection, latency of the virus occurs, followed by subsequent recurrences of herpetic keratitis. Such recurrences may lead to structural damage of the cornea. Recurrent herpetic keratitis is a common indication for corneal transplantation. Recurrences of herpetic keratitis in the corneal graft may lead to corneal graft rejection. Several antiviral agents for HSV are available, including the thymidine analogs. Prolonged use of thymidine analogs may lead to toxicity of the ocular surface, including epithelial keratitis, corneal ulcers, follicular conjunctivitis, and punctal occlusions. Availability of topical antiviral agents that are safe and effective in the treatment and prophylaxis of herpetic keratitis is highly desirable. Ganciclovir is a potent inhibitor of members of the herpes virus family. The drug has been used systemically for the treatment of cytomegalovirus (CMV) retinitis. Its hematologic toxicity secondary to systemic administration led to its limited use in herpetic infections. On the other hand, topical ganciclovir has been shown to be as safe and effective as acyclovir in the treatment of herpetic epithelial keratitis. Furthermore, topical ganciclovir can reach therapeutic levels in the cornea and aqueous humor following topical application. Several clinical trials have shown that topical ganciclovir 0.15% ophthalmic gel is safe and effective in the treatment and prophylaxis of herpetic epithelial disease. Long-term use of ganciclovir ophthalmic gel in patients with penetrating keratoplasty following herpetic keratitis has prevented recurrences of the disease. Topical ganciclovir ophthalmic gel is well tolerated, does not cause toxic effects on the ocular surface, and does not cause hematologic abnormalities. Clinical studies have underscored the potential role of ganciclovir ophthalmic gel in the treatment and

Objectives: To establish patterns of use and adherence with topical treatments for AK and to identify treatment-related factors that impact on adherence. Methods: A community-based, cross-sectional study was performed using a standardized questionnaire completed online or via telephone interview. Patients were stratified according to the presence of AK lesions on the scalp and/or other extremities; and presence of scarring resulting from treatment. Results: This study included 305 patients with AK who were currently using a patient-applied topical therapy for AK or had used one within the previous 12 months. In total, 88% (n = 268/305 of patients were either non-adherent, non-persistent or both non-adherent and non-persistent to topical therapy. Duration of treatment was associated with increasing rates of non-adherence (adjusted odds ratio [OR]; for treatment durations greater than 4 weeks, 2.2, P < 0.01: 52% of patients were non-adherent with 3–4 week treatment duration; 69% of patients with 4–8 week treatment duration; and 71% of patients with 6–12 week treatment duration. There were similar increases in non-persistence with increasing treatment duration (adjusted OR; for treatment durations greater than 4 weeks, 2.1, P < 0.05. Conclusion: This study found high rates of non-adherence and non-persistence in patients with AK. Duration of treatment was a significant factor contributing to non-adherence and non-persistence to topical treatments. Patient-applied topical therapies that require less frequent application and have shorter treatment duration may be associated with improved

    Full Text Available Niklas Schuelert, Fiona A Russell, Jason J McDougallDepartment of Physiology and Pharmacology, University of Calgary, Calgary, AB, CanadaAbstract: Osteoarthritis (OA is a common disease that affects millions of people worldwide. As there is no cure for OA, drug treatment to relieve symptoms is the main form of management. Nonsteroidal anti-inflammatory drugs (NSAIDs such as diclofenac are the most commonly used drugs to treat knee OA pain. Unfortunately, these agents are associated with gastrointestinal and cardiovascular risks, which limit their chronic use. Topical NSAIDs are emerging as a viable alternative for managing OA pain. Because a pharmacologically effective dose can be restricted to the site of pain, there is superfluous systemic absorption, and the risk of related adverse effects is minimized. This article reviews the currently available preclinical and clinical information on topical diclofenac for the treatment of OA pain, including data from recently published randomized controlled trials regarding the efficacy and safety of topical diclofenac. Most studies confirm topical diclofenac to be as effective as oral diclofenac with significantly reduced side effects; however, the efficacy of NSAIDs is far from optimal, and more research needs to be done to investigate the underlying mechanisms of OA in order to improve treatment options, especially for patients with NSAID-resistant OA pain.Keywords: osteoarthritis, topical diclofenac, NSAID, joint pain

    Topical treatment of mild to moderate psoriasis is first-line treatment and exhibits varying degrees of success across patient groups. Key factors influencing treatment success are physician topical treatment choice (high efficacy, low adverse events) and strict patient adherence. Currently, no formalized, international consensus guidelines exist to direct optimal topical treatment, although many countries have national guidelines. To describe and analyse cross-regional variations in the use and access of psoriasis topical therapies. The study was conducted as an observational cross-sectional study. A survey was distributed to dermatologists from the International Psoriasis Council (IPC) to assess topical therapy accessibility in 26 countries and to understand how body surface area (BSA) categories guide clinical decisions on topical use. Variation in the availability of tars, topical retinoids, dithranol and balneotherapy was reported. The vast majority of respondents (100% and 88.4%) used topical therapy as first-line monotherapy in situations with BSA 10%, the number of respondents who prescribe topical therapy decreased considerably. In addition, combination therapy of a topical drug and a systemic drug was frequently reported when BSA measured >10%.

    This article describes topical therapies and treatment guidelines for psoriasis and is based on a presentation given by the authors at a satellite symposium held during the 19th Congress of the European Academy of Dermatology and Venereology, 6-10 October, 2010, in Gothenburg, Sweden. The highly variable nature of psoriasis and its individual presentation in patients can make it difficult to choose the most appropriate treatment. There are many treatment options, from topical treatment with emollients for very mild psoriasis, to systemic therapy with fumaric acid esters, methotrexate or biologics for severe disease. For the treatment of mild-to-moderate psoriasis, topical therapy is generally the most appropriate and a variety of options, both historical and recent, are available. Newer therapies offer greater convenience and fewer side-effects. Of the more recently available therapies, vitamin D analogues and topical corticosteroids are the two with the greatest proven efficacy in randomized clinical trials. A recent Cochrane review showed the highest efficacy overall with the fixed combination vitamin D analogue (calcipotriol) and corticosteroid (betamethasone dipropionate). Indeed, clinical trials have shown that two-compound calcipotriol\\/betamethasone dipropionate ointment has higher efficacy than calcipotriol or betamethasone dipropionate alone. With regard to safety, two-compound calcipotriol\\/betamethasone dipropionate was shown to be suitable for intermittent long-term treatment of mild-to-moderate psoriasis. The findings of the Cochrane review are reflected in the current treatment guidelines from the USA and Germany regarding the treatment of mild-to-moderate psoriasis. In both these guidelines, which will be discussed in this article, the recommended treatments for this patient group are vitamin D analogues and corticosteroids, particularly when used in combination.

    2017-01-01

    Background: Diabetes Mellitus is a pandemic of the modern era owing to our rapidly deteriorating lifestyle. Painful diabetic neuropathy is one of the costliest and disabling complications of diabetes mellitus. No single treatment exists to prevent or reverse neuropathic changes or to provide total pain relief. Topical Capsaicin and Turpentine Oil are found to be effective in treatment of painful diabetic neuropathy. Methods: Patients of either gender with ages between 18 and 70 years having painful diabetic neuropathy already taking one oral drug for painful neuropathy and treatment for diabetes mellitus and an HbA1C less than 8.5% were included while Pregnant or lactating mothers, patients with chronic liver disease and patients with renal insufficiency (creatinine >3.0 mg/dl) and peripheral arterial disease were excluded from study. Patients were randomly divided into two groups (A and B) using computer generated random number table. Group A was given topical application of capsaicin while Group B was given topical application of commercially available turpentine oil over painful site on feet. Results: 300 patients were equally divided in two groups. The patients in group A had a Visual Analog Pain Score of 7.91±5.10 at baseline and 5.10±1.343 after 3 months of treatment (p-value 0.0001). The patients in group B had a Visual Analog Pain Score of 7.83±1.012 at baseline and 5.20±1.187 after 3 months of treatment (p-value 0.0001). Chi Square test was applied to compare efficacy of both groups. It was noted that 71 (53%) had efficacy in group A and 63 (47%) had efficacy in the group B but the difference was not statistically significant. (p-value=0.399). Conclusion: It has been concluded that turpentine oil is effective in managing diabetic neuropathic pain similar to capsaicin cream.

    2017-06-01

    Osteoarthritis (OA) is one of the most common causes of joint pain in the United States and non-steroidal anti-inflammatories (NSAIDs), such as Diclofenac sodium, which is currently available in two main routes of administration; oral and topical distribution have been established as one of the standard treatments for OA. Generally, oral NSAIDs are well tolerated; however our narrative review suggests that the topical solution had a better tolerability property than oral Diclofenac sodium, especially due to side effects of gastrointestinal bleeding with the utilization of the oral format. In addition, the topical route may be considered a reasonable selection by clinicians for management of musculoskeletal pain in those patients with a history of potential risk and adverse side effects. Most studies reviewed comparing oral versus topical solution of Diclofenac sodium revealed comparable efficacy, with minimal side effects utilizing the topical route. The key point of this narrative review is to help clinicians that currently must decide between very inexpensive diclofenac oral presentations and expensive topical presentations especially in the elderly population and the pros and cons of such decision-making process.

    Full Text Available A select group of patients with upper tract urothelial carcinoma may be appropriate candidates for minimally invasive management. Organ-preserving endoscopic procedures may be appropriate for patients with an inability to tolerate major surgery, solitary kidney, bilateral disease, poor renal function, small tumor burden, low-grade disease, or carcinoma in situ. We review the published literature on the use of topical treatment for upper tract urothelial carcinoma and provide our approach to treatment in the office setting.

    Full Text Available Khalid F Tabbara1,2,3, Noorjehan Al Balushi11The Eye Center and The Eye Foundation for Research in Ophthalmology, Riyadh, 2Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia; 3The Wilmer Ophthalmological Institute of The Johns Hopkins University School of Medicine, Baltimore, Maryland, USAAbstract: Herpetic keratitis is caused by herpes simplex virus (HSV and is a common cause of corneal blindness. Following a primary ocular herpetic infection, latency of the virus occurs, followed by subsequent recurrences of herpetic keratitis. Such recurrences may lead to structural damage of the cornea. Recurrent herpetic keratitis is a common indication for corneal transplantation. Recurrences of herpetic keratitis in the corneal graft may lead to corneal graft rejection. Several antiviral agents for HSV are available, including the thymidine analogs. Prolonged use of thymidine analogs may lead to toxicity of the ocular surface, including epithelial keratitis, corneal ulcers, follicular conjunctivitis, and punctal occlusions. Availability of topical antiviral agents that are safe and effective in the treatment and prophylaxis of herpetic keratitis is highly desirable. Ganciclovir is a potent inhibitor of members of the herpes virus family. The drug has been used systemically for the treatment of cytomegalovirus (CMV retinitis. Its hematologic toxicity secondary to systemic administration led to its limited use in herpetic infections. On the other hand, topical ganciclovir has been shown to be as safe and effective as acyclovir in the treatment of herpetic epithelial keratitis. Furthermore, topical ganciclovir can reach therapeutic levels in the cornea and aqueous humor following topical application. Several clinical trials have shown that topical ganciclovir 0.15% ophthalmic gel is safe and effective in the treatment and prophylaxis of herpetic epithelial disease.

  12. Transdermal and Topical Drug Administration in the Treatment of Pain

    Directory of Open Access Journals (Sweden)

    Wojciech Leppert

    2018-03-01

    Full Text Available The comprehensive treatment of pain is multidimodal, with pharmacotherapy playing a key role. An effective therapy for pain depends on the intensity and type of pain, the patients’ age, comorbidities, and appropriate choice of analgesic, its dose and route of administration. This review is aimed at presenting current knowledge on analgesics administered by transdermal and topical routes for physicians, nurses, pharmacists, and other health care professionals dealing with patients suffering from pain. Analgesics administered transdermally or topically act through different mechanisms. Opioids administered transdermally are absorbed into vessels located in subcutaneous tissue and, subsequently, are conveyed in the blood to opioid receptors localized in the central and peripheral nervous system. Non–steroidal anti–inflammatory drugs (NSAIDs applied topically render analgesia mainly through a high concentration in the structures of the joint and a provision of local anti–inflammatory effects. Topically administered drugs such as lidocaine and capsaicin in patches, capsaicin in cream, EMLA cream, and creams containing antidepressants (i.e., doxepin, amitriptyline act mainly locally in tissues through receptors and/or ion channels. Transdermal and topical routes offer some advantages over systemic analgesic administration. Analgesics administered topically have a much better profile for adverse effects as they relieve local pain with minimal systemic effects. The transdermal route apart from the above-mentioned advantages and provision of long period of analgesia may be more convenient, especially for patients who are unable to take drugs orally. Topically and transdermally administered opioids are characterised by a lower risk of addiction compared to oral and parenteral routes.

    Full Text Available Background: The skin is one of the most affected organs in tuberous sclerosis complex and angiofibromas are seen in almost 80% of such patients. These benign tumors impose a great psycho-social burden on patients. Objective: The aim of the study was to evaluate the effectiveness and tolerability of topical sirolimus for facial angiofibromas in patients with tuberous sclerosis complex. Methods: This was a prospective, single-blinded, cross-over study which involved twelve patients. We investigated the effect and safety of topical 0.1% sirolimus, which was obtained by crushing sirolimus tablets and mixing it with petrolatum. The patients were asked to apply the cream to one side of their face, and vaseline to the other side. The effect of topical sirolimus was evaluated using the “facial angiofibroma severity index.” Results: There was a significant improvement in the redness and extension of the tumors on the sides to which the active ingredient was applied. Some side effects such as itching and irritation occurred in three patients, which were treated with topical hydrocortisone cream. Conclusion: Topical sirolimus appears to be a promising, fairly well tolerated treatment for facial angiofibromas in patients with tuberous sclerosis complex. Although its efficacy diminishes with time, repetitive usage is effective.

  14. Acute Toxicity from Topical Cocaine for Epistaxis: Treatment with Labetalol.

    2017-03-01

    Topical cocaine is sometimes used for the treatment of epistaxis, as it has both potent anesthetic and vasoconstrictive properties. Cocaine has unpredictable cardiovascular effects, such as sudden hypertension, tachycardia, coronary arterial vasoconstriction, and dysrhythmia. We report a case of acute iatrogenic cardiovascular toxicity from the use of topical cocaine in a 56-year-old man presenting to the Emergency Department with profound epistaxis. To prepare for cauterization and nasal packing, the patient received 4% topical cocaine-soaked nasal pledgets. He became hypertensive, tachypneic, tachycardic, and dysphoric immediately after administration. To directly counter these adverse hyperadrenergic effects, the patient was given 10 mg intravenous labetalol, a mixed β- and α-blocker. This instantly normalized his vital signs and adverse subjective effects. His epistaxis was successfully treated, and he was discharged 1 h later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We believe that emergency physicians should be aware of the unpredictable acute cardiovascular toxicity of topical cocaine. Labetalol represents an effective first-line treatment, which, unlike benzodiazepines, directly counters the pharmacologic effects of cocaine and has no respiratory or sedative side effects. Labetalol, with its mixed β/α-blocking properties, also mitigates the potential for "unopposed α-stimulation." Copyright © 2016 Elsevier Inc. All rights reserved.

    1975-12-01

    Twenty-six patients with mycosis fungoides were treated topically with three nitrosourea compounds: carmustine (BCNU), lomustine (CCNU), and 1-methyl-1-nitrosourea. A high percentage experienced good to excellent results. Remissions following treatment of individual lesions varied from one month to at least three years. Remissions following total body surface treatment varied from two weeks to at least four months. Two of 13 patients treated over the entire body suffered temporary bone marrow depression, indluding one with severe pancytopenia. This toxic effect was attributed to lomustine and was not seen in patients treated with carmustine alone. Thirteen patients highly allergic to mechlorethamine hydrochloride showed no cross-sensitivity to nitrosourea compounds. A primary irritant dermatitis occurred in about one half of the patients and telangiectasia in two. Two patients developed hypersensitivity to nitrosourea compounds. Carmustine is the preferred nitrosourea compound for topical therapy of mycosis fungoides.

    To investigate the effects of topical vitamin E and hydrocortisone acetate treatments on corneal healing response after -10.0 D photorefractive keratectomy (PRK) in rabbits. Thirty-three New Zealand white rabbits were divided into four groups and -10 D PRK was performed under in vivo conditions. Following PRK, group 1 (n = 9) received no topical treatment and served as control. Group 2 (n = 8) received 0.1% hydrocortisone acetate ointment twice a day, group 3 (n = 8) received 1% vitamin E ointment and group 4 (n = 8) received both 0.1% hydrocortisone acetate and 1% vitamin E twice a day for a month. At the end of the third month, corneal haze was graded and the corneal hydroxyproline levels were measured, as a crude indicator of new collagen synthesis. Finally corneal samples were examined by transmission electron microscopy. Non-homogeneously distributed strong haze was identified in group 1 which was greater than in the other groups; haze was least in groups 2 and 4. Corneal hydroxyproline levels were found to be significantly lower in groups 2, 3 and 4 compared with the control (Student's t-test, p < 0.05). Histopathologically, the most aggressive wound healing response was detected in group 1. The corneal wound healing response of group 2 was less than that of group 1 and equal to or more than that of group 4. Deep corneal photoablation induces an aggressive healing response, and topical hydrocortisone acetate reduces this corneal wound healing effectively. The inhibitory effect of topical vitamin E on corneal wound healing seems to be less than that of hydrocortisone acetate, but combined treatment with these two drugs may have an additive effect in controlling corneal wound healing after PRK.

    2012-01-01

    Full Text Available Abstract Background Common warts (verruca vulgaris are benign epithelial proliferations associated with human papillomavirus (HPV infection. Salicylic acid and cryotherapy are the most frequent treatments for common warts, but can be painful and cause scarring, and have high failure and recrudescence rates. Topical vitamin A has been shown to be a successful treatment of common warts in prior informal studies. Case The subject is a healthy, physically-active 30 old female with a 9 year history of common warts on the back of the right hand. The warts resisted treatment with salicylic acid, apple cider vinegar and an over-the-counter blend of essential oils marketed for the treatment of warts. Daily topical application of natural vitamin A derived from fish liver oil (25,000 IU led to replacement of all the warts with normal skin. Most of the smaller warts had been replaced by 70 days. A large wart on the middle knuckle required 6 months of vitamin A treatment to resolve completely. Conclusion Retinoids should be further investigated in controlled studies to determine their effectiveness in treating common warts and the broad range of other benign and cancerous lesions induced by HPVs.

    Purpose To examine the effect of topical ranibizumab on clinically stable corneal neovascularization (NV). Methods This was a prospective, open-label, monocentric, uncontrolled, non-comparative study. Ten eyes of 9 patients with corneal NV received topical ranibizumab (1%) 4 times a day for 3 weeks with a follow-up of 16 weeks. The main corneal neovascularization outcome measures were: neovascular area (NA), the area occupied by the corneal neovessels; vessel caliber (VC), the mean diameter of the corneal neovessels; and invasion area (IA), the fraction of the total cornea area covered by the vessels. This study was conducted at the Massachusetts Eye and Ear Infirmary, Boston, MA, USA. Results Statistically significant decreases in NA (55.3%, P<0.001), which lasted through 16 weeks, and VC (59%, P<0.001), which continued to improve up to week 16, were observed after treatment. No significant decrease was observed in IA (12.3%, P=0.49). There was no statistically significant change in visual acuity or intraocular pressure. No adverse events ascribed to the treatment were noted. Conclusions Topical application of ranibizumab is effective in reducing the severity of corneal NV in the context of established corneal NV, mostly through decrease in VC rather than IA.

    Scheinfeld, Noah

    2014-07-15

    Hidradenitis Supprurativa (HS) is a painful chronic follicular disease. Few papers have addressed pain control for this debilitating condition. Possible topical agents include tricyclic antidepressants, opioids, anticonvulsants, NSAIDs, NMDA receptor antagonists, local anesthetics and other agents. The first line agents for the topical treatment of the cutaneous pain of HS are diclonefac gel 1% and liposomal xylocaine 4% and 5% cream or 5% ointment. The chief advantage of topical xylocaine is that is quick acting i.e. immediate however with a limited duration of effect 1-2 hours. The use of topical ketamine, which blocks n-methyl-D-aspartate receptors in a non-competitive fashion, might be a useful tool for the treatment of HS pain. Topical doxepin, which available in a 5% commercially preparation (Zonalon®) , makes patients drowsy and is not useful for controlling the pain of HS . Doxepin is available in a 3% or 3.3% concentration (which causes less drowsiness) from compounding pharmacies and can be used in compounded analgesic preparations with positive effect. Topical doxepin is preferred over use of topical amitriptyline because topical doxepin is more effective. Nevertheless, topical amitriptyline increase of the tactile and mechanical nociceptive thresholds and can be used for topical pain control in compound mixture of analgesics . Gabapentin and pregablin can also be used compounded with other agents in topical analgesic preparations with positive topical anesthetic effect. Capsaicin is not useful for topical treatment of the pain of HS. Sometimes compounded of anesthetics medications such as ketamine 10%, bupivacaine 1%, diclofenac 3%, doxepin 3% or 3.3%, and gabapentin 6% can extend the duration of effect so that medication only needs to be used 2 or 3 times a day. Still in my experience the easiest to get and most patient requested agent is topical diclonefac 1% gel.

    2011-01-01

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    Rowlands, Megan A; Giacometti, Joseph N; Servat, Javier; Materin, Miguel A; Levin, Flora

    Conjunctival actinic keratosis is rare and difficult to treat, as recurrences are common. Imiquimod, an immune response modulator, is currently Food and Drug Administration-approved for cutaneous actinic keratosis and superficial basal cell carcinomas. Emerging reports have shown it to be effective in treating some periocular and conjunctival lesions. The authors present a case of a 68-year-old white man with recurrent actinic keratosis involving the pretarsal conjunctiva, which was successfully treated with 5% topical imiquimod following previous failure with cryotherapy and interferon α-2b. The patient had ocular irritation that resolved on cessation of treatment. To the authors' knowledge, this is the first report of conjunctival actinic keratosis being treated with and successfully eradicated by topical imiquimod.

    Existing therapies for vitiligo are limited in efficacy and can be associated with undesirable side effects. Topical Janus kinase inhibitors may offer a new therapeutic option for vitiligo. We sought to assess the role of topical ruxolitinib 1.5% cream, a Janus kinase inhibitor, in vitiligo treatment. This 20-week, open-label, proof-of-concept trial of twice-daily topical ruxolitinib 1.5% cream was conducted in 12 patients with a minimum of 1% affected body surface area of vitiligo. The primary outcome was percent improvement in Vitiligo Area Scoring Index from baseline to week 20. Of 12 patients screened, 11 were enrolled and 9 completed the study (54.5% men; mean age, 52 years). Four patients with significant facial involvement at baseline had a 76% improvement in facial Vitiligo Area Scoring Index scores at week 20 (95% confidence interval, 53-99%; P = .001). A 23% improvement in overall Vitiligo Area Scoring Index scores was observed in all enrolled patients at week 20 (95% confidence interval, 4-43%; P = .02). Three of 8 patients responded on body surfaces and 1 of 8 patients responded on acral surfaces. Adverse events were minor, including erythema, hyperpigmentation, and transient acne. Limitations of the study include the small sample size and open-label study design. Topical ruxolitinib 1.5% cream provided significant repigmentation in facial vitiligo and may offer a valuable new treatment for vitiligo. Copyright © 2017 American Academy of Dermatology, Inc.

    2005-03-01

    Necrotic angiodermatitis is a variety of leg ulcer, characterized by very painful and rapidly spreading lesions. Healing takes time, a mean of 4 to 11 months. Current treatment is difficult and rarely satisfactory. Only early skin grafts lead to rapid sedation of pain and stop the lesion from extending. However, this technique, performed during a progressive phase, enhances the risk of losing a certain number of grafts. We wanted to confirm the efficacy of local auto-haemo-therapy proposed in 2 non-controlled studies. Eleven patients with necrotic angiodermatitis were included in our non-controlled prospective study. The topical hemotherapy was applied three times a week for one month, with initial hospitalization for 15 days. The criteria of assessment were: evolution of pain, surface of the ulcer, colorimetric scale and the date of disappearance of the purple halo. Ten patients were relieved by the treatment, with progressive withdrawal of the analgesics. The progression of the lesion had stopped and the purple halo had disappeared in general by D6 (range: 2 to 21 days). The percentage of granulation tissue with regard to the surface of the ulcer was of 45.4 p. 100 on D0, 80 p. 100 on D14 and 85 p. 100 on D28. Topical hemotherapy applied during the initial phase of treatment would reduce the pain and prepare the lesion for a secondary skin graft.

  4. Systemic vs. Topical Therapy for the Treatment of Vulvovaginal Candidiasis

    1994-01-01

    Full Text Available It is estimated that 75% of all women will experience at least 1 episode of vulvovaginal candidiasis (VVC during their lifetimes. Most patients with acute VVC can be treated with short-term regimens that optimize compliance. Since current topical and oral antifungals have shown comparably high efficacy rates, other issues should be considered in determining the most appropriate therapy. It is possible that the use of short-duration narrow-spectrum agents may increase selection of more resistant organisms which will result in an increase of recurrent VVC (RVVC. Women who are known or suspected to be pregnant and women of childbearing age who are not using a reliable means of contraception should receive topical therapy, as should those who are breast-feeding or receiving drugs that can interact with an oral azole and those who have previously experienced adverse effects during azole therapy. Because of the potential risks associated with systemic treatment, topical therapy with a broad-spectrum agent should be the method of choice for VVC, whereas systemic therapy should be reserved for either RVVC or cases where the benefits outweigh any possible adverse reactions.

    2005-08-01

    Full Text Available OBJECTIVES: To correlate topical steroidal treatment of stenosed foreskin with the different degrees of glans exposure and the length of time the ointment is applied. MATERIALS AND METHODS: We studied 95 patients with phimosis, divided according to the degree of foreskin retraction. Group A presented no foreskin retraction, group B presented exposure of only the urethral meatus, group C presented exposure of half of the glans, and group D presented exposure of the glans, which was incomplete because of preputial adherences to the coronal sulcus. Patients were submitted to application of 0.05% betamethasone ointment on the distal aspect of the prepuce twice daily for a minimum of 30 days and a maximum of 4 months. RESULTS: Of 95 patients, 10 (10.52% abandoned the treatment and 15 patients in groups C and D were excluded from the study. Among the remaining 70 patients, only 4 patients (5.7% in group A did not obtain adequate glans exposure after treatment. In group A (38 patients, fully retractable foreskins were obtained in 19 patients (50% after 1 month of treatment. In group B (28 patients, fully retractable foreskins were obtained in 18 patients (64.2% after 1 month. CONCLUSIONS: Treatment was successful in 94.2% of patients, irrespective of the type of foreskin anatomy. The improvement may require several months of treatment. Patients with impossibility of urethral meatus exposure present around 10% treatment failure.

    2017-05-01

    Full Text Available In the last two decades, many new peptides have been developed, and new knowledge on how peptides improve the skin has been uncovered. The spectrum of peptides in the field of cosmetics is continuously growing. This review summarizes some of the effective data on cosmeceutical peptides that work against intrinsic and extrinsic aging. Some peptides have been proven in their efficacy through clinical skin trials. Well-known and documented peptides like copper tripeptide are still under research to obtain more details on their effectiveness, and for the development of new treatments. Palmitoyl pentapeptide-4 and Carnosine are other well-researched cosmeceuticals. Additionally, there are many more peptides that are used in cosmetics. However, study results for some are sparse, or have not been published in scientific journals. This article summarizes topical peptides with proven efficacy in controlled in vivo studies.

    Full Text Available Abstract OBJECTIVE To evaluate the costs of a topical treatment of pressure ulcer (PU patients in a hospital unit for treatment of chronic patients in 2014. METHOD This is an activity-based costing study. This method encompasses the identification, measurement and pricing of physical and human resources consumed for dressings. RESULTS Procedure costs varied between BRL 16.41 and BRL 260.18. For PUs of the same category, of near areas and with the same type of barrier/adjuvant, the cost varied between 3.5% and 614.6%. For most dressings, the cost increased proportionally to the increase of the area and to the development of PU category. The primary barrier accounted for a high percentage of costs among all items required to the application of dressings (human and material resources. Dressings applied in sacral PUs had longer application times. CONCLUSION This study allowed us to understand the costs involved in the treatment of PUs, and it may support decision-makers and other cost-effectiveness studies.

    The success of many medical treatments is built on compliance. Electronic monitoring is the most accurate tool to quantify compliance by measuring adherence. In order to assess the efficiency of a recently introduced miniature monitoring device for eye drop application, we evaluated adherence in ophthalmic patients undergoing post-operative short-term topical treatment. This pilot study enrolled 30 outpatients (mean age 61.8 +/- 18.5 years) after cataract (n = 24) and glaucoma filtration surgery (n = 6) applying fixed-combination eye drops containing prednisolone and gentamicin five times daily for 2 weeks. Patients received eye drops in conventional bottles each equipped with a miniature monitoring device recording events of application. Two patients failed to bring back the monitoring device; therefore data collected from only 28 patients could be examined. Data showed highly variable results with a mean dose compliance of 50.2%. Dose compliance was below 25% in approximately one out of five patients. Four cataract patients, but no glaucoma patient, discontinued therapy prematurely. The observed mean dosage interval was calculated for each patient and ranged 4.6-19.7 h. Thirty percent of analysed dosage intervals exceeded 12.0 h. Different patterns of compliance behaviour-like early non-persistence, drug holiday and low treatment frequency could be identified and illustrated using electronic data. Age or gender did not significantly influence compliance rates. Our pilot study demonstrates successful electronic compliance monitoring using a technology capable of continuous data recording over weeks of treatment. The low compliance rate for a relevant part of the patients demonstrates the necessity to study and improve compliance in ophthalmology. In future, new application methods and electronic application devices may improve treatment response in eye care.

    Periodic fluctuations in past biodiversity, speciation, and extinction have been proposed, with extremely long periods ranging from 26 to 62 million years, although forcing mechanisms remain speculative. In contrast, well-understood periodic Milankovitch climate forcing represents a viable driver for macroevolutionary fluctuations, although little evidence for such fluctuation exists except during the Late Cenozoic. The reality, magnitude, and drivers of periodic fluctuations in macroevolutionary rates are of interest given long-standing debate surrounding the relative roles of intrinsic biotic interactions vs. extrinsic environmental factors as drivers of biodiversity change. Here, we show that, over a time span of 60 million years, between 9 and 16% of the variance in biological turnover (i.e., speciation probability plus species extinction probability) in a major Early Paleozoic zooplankton group, the graptoloids, can be explained by long-period astronomical cycles (Milankovitch "grand cycles") associated with Earth's orbital eccentricity (2.6 million years) and obliquity (1.3 million years). These grand cycles modulate climate variability, alternating times of relative stability in the environment with times of maximum volatility. We infer that these cycles influenced graptolite speciation and extinction through climate-driven changes to oceanic circulation and structure. Our results confirm the existence of Milankovitch grand cycles in the Early Paleozoic Era and show that known processes related to the mechanics of the Solar System were shaping marine macroevolutionary rates comparatively early in the history of complex life. We present an application of hidden Markov models to macroevolutionary time series and protocols for the evaluation of statistical significance in spectral analysis.

    Full Text Available INTRODUCTION: There are various approaches to the treatment of cutaneous tumors; one of them is treatment with imiquimod, a synthetic toll-like receptor agonist with a low molecular weight that offers a topical, noninvasive, and non-surgical therapeutic option. The main objective of our study was to provide data on 89 patients who used a 5% imiquimod cream for the treatment of cutaneous tumors at the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas from 2003 to 2008. MATERIALS AND METHODS: Here, we present our experience in the treatment of 123 cutaneous tumors of various types, including basal cell carcinoma (BCC, squamous cell carcinoma (SCC, Bowen's disease, erythroplasia of Queyrat, Paget's disease, and trichoepithelioma, with 5% imiquimod cream from 2003 to 2008 in the Cutaneous Oncology Group of the Dermatology Department of Hospital das Clinicas. Patients were divided into two separate groups according to their diagnosis and comorbidities; these comorbidities included epidermodysplasia verruciformis, xeroderma pigmentosum, albinism, basal cell nevus syndrome, Brooke-Spiegler syndrome, HIV, chronic lymphocytic leukemia, B-cell lymphoma, and kidney transplantation. Treatment duration, response to imiquimod, follow-up, recurrence, and local and systemic reactions associated with use of the drug were analyzed. Epidemiological data were obtained and cure rates were calculated. RESULTS: The ratio of women to men was 1.28:1, and the mean age was 63.1 years. Tumors were located mainly on the face, back, trunk, and legs. For patients with comorbidities, the overall cure rate was 38%. These specific patients demonstrated cure rates of 83.5% for superficial BCC and 50% for Bowen's disease. Aggressive BCC and superficial and nodular BCC did not present a good response to treatment. Trichoepitheliomas and nodular BCC showed a partial response, and erythroplasia of Queyrat showed a complete response. For patients without

    Full Text Available Adele Sparavigna, Beatrice Tenconi, Ileana De Ponti, Laura La PennaDermIng srl, Clinical Research and Bioengineering Institute, Monza, MB, ItalyAbstract: Acne is characterized by primary lesions on the face, chest, and back, and by a variety of other signs and symptoms. In particular, acne inflammatory lesions result from Propionibacterium acnes colonization and are of particular relevance as they can cause permanent scarring. Acne also causes significant psychological morbidity in affected patients. Products currently available for the treatment of acne include systemic and topical treatments. As these products can cause severe side effects, new, innovative therapies are needed. Farmaka Acne Cream (FAC is a novel, film-forming cream developed to treat mild and moderate acne. In vitro studies have demonstrated that FAC is as effective as 5% benzoyl peroxide in inhibiting growth of P. acnes. In 32 subjects with mild or moderate acne, FAC reduced all the major signs and symptoms of the disease. These included itching, erythema, and scaling, as well as reductions in the numbers of papules, pustules, and open and closed comedones. Acne severity improved in 38% of subjects, while none worsened. FAC was found to be effective in controlling sebum secretion, and was non-comedogenic. Most subjects (90% reported tolerability as good or very good, while clinical efficacy and cosmetic acceptability were judged as good. For assessment of contact sensitization and photosensitization, FAC was applied daily to the backs of 29 subjects in two symmetric areas for 10 days. Using a solar stimulator, one minimal erythema dose was delivered to one side of the back from days 11 to 13. The four different subareas of treated/untreated and irradiated/nonirradiated and combinations thereof were compared. No cases of contact sensitization or photosensitization were observed, and FAC is considered safe for use in intense sunlight. In vitro and in vivo studies provide

    To evaluate the costs of a topical treatment of pressure ulcer (PU) patients in a hospital unit for treatment of chronic patients in 2014. This is an activity-based costing study. This method encompasses the identification, measurement and pricing of physical and human resources consumed for dressings. Procedure costs varied between BRL 16.41 and BRL 260.18. For PUs of the same category, of near areas and with the same type of barrier/adjuvant, the cost varied between 3.5% and 614.6%. For most dressings, the cost increased proportionally to the increase of the area and to the development of PU category. The primary barrier accounted for a high percentage of costs among all items required to the application of dressings (human and material resources). Dressings applied in sacral PUs had longer application times. This study allowed us to understand the costs involved in the treatment of PUs, and it may support decision-makers and other cost-effectiveness studies.

    A modified double blind crossover study was performed to assess the effect of 1% topical minoxidil as compared with placebo in 30 patients with alopecia areata and alopecia totalis. The active preparation produced a highly significant incidence of hair regrowth. A cosmetically acceptable response was noted in 16 patients. No side effects were seen. The study confirmed that topical minoxidil will induce new hair growth in alopecia areata but that it is less likely to do so in more severe and extensive disease. Furthermore, patients with alopecia universalis and totalis may not respond at all. Nevertheless, as compared with other drugs minoxidil applied topically is relatively non-toxic, is easy to use, and has no systemic or local side effects. Images p1016-a PMID:6412929

    A neuropathy is a disturbance of function or pathological change in nerves. In some cases, peripheral neuropathic pain may occur due to a lesion or disease of the peripheral somatosensory nervous system. Efficacy of different agents for peripheral neuropathic pain conditions is less than optimal. The administration of topical analgesics might be an option, due to the potential of reduced adverse effects and increased patient compliance. There is major interest in compounding topical analgesics for peripheral neuropathic pain, but several challenges remain for this approach. Topical analgesics have the potential to be a valuable additional approach for the management of peripheral neuropathic pain. Topical amitriptyline-ketamine combination (AK) is a promising agent for peripheral neuropathic pain conditions. Some studies have shown its efficacy in neuropathic pain conditions. However, this data was not uniformely obtained and its role remains still controversial. Efficacy may depend on many factors, including the choice of the vehicle, the concentration, the pain site, and specific diseases. More studies are necessary to support the use of AK in clinical practice.

    Various treatment modalities are available for management of melasma, ranging from topical and oral to chemical peeling, but none is promising alone. Very few studies are available regarding efficacy of combination of topical treatment with chemical peeling. Combination of chemical peeling and topical regimen can be a good treatment modality in the management of this recalcitrant disorder. To assess the efficacy of combination of topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling in the treatment of melasma in Indian patients. Forty Indian patients of moderate to severe epidermal variety melasma were divided into two groups of 20 each. One Group i.e. peel group received topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling and other group i.e. control group received topical regimen (2% hydroquinone, 1% hydrocortisone, 0.05% tretinoin). There was an overall decrease in MASI from baseline in 24 weeks of therapy in both the groups (P value peel with topical regimen showed early and greater improvement than the group which was receiving topical regimen only. This study concluded that combining topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling significantly enhances the therapeutic efficacy of glycolic acid peeling. The combination of glycolic acid peeling with the topical regimen is a highly effective, safe and promising therapeutic option in treatment of melasma.

    Full Text Available Objectives: Oral lichen planus (OLP is a chronic inflammatory disorder of unknown etiology that affects the skin and the mucosa, especially the oral mucosa. Several therapeutic agents have been investigated for the treatment of OLP. All agents used in the OLP therapy are palliative. Potent topical steroids are used as the conventional therapy for OLP. Since side-effects or steroid resistance may be encountered, alternative treatments may be necessary. This study aimed to evaluate the efficacy and safety of the topical pimecrolimus in the treatment of OLP. Methods: Seventeen patients with OLP were recruited into this study. Topical pimecrolimus 1% cream was applied twice a day to the affected areas. Patients were followed up for 3-6 months. Photographs of the lesions were taken and analyzed for areas of ulceration, erythema, and reticulation in every clinical examination. Results: We found that topical pimecrolimus 1% cream was an effective treatment for OLP. Two patients could not complete the treatment protocol because of the side effects such as local irritation and nausea. Conclusion: Topical pimecrolimus may be a valuable second treatment choice for patients with steroid-related side-effects or steroid-resistant OLP. However further randomized controlled studies have to be conducted to compare conventional treatment of topical corticosteroid with topical pimecrolimus.

    This randomized controlled trial aimed to investigate the distinctness after treatment among hot herbal compress, hot compress, and topical diclofenac. The registrants were equally divided into groups and received the different treatments including hot herbal compress, hot compress, and topical diclofenac group, which served as the control group. After treatment courses, Visual Analog Scale and 36-Item Short Form Health survey were, respectively, used to establish the level of pain intensity and quality of life. In addition, cervical range of motion and pressure pain threshold were also examined to identify the motional effects. All treatments showed significantly decreased level of pain intensity and increased cervical range of motion, while the intervention groups exhibited extraordinary capability compared with the topical diclofenac group in pressure pain threshold and quality of life. In summary, hot herbal compress holds promise to be an efficacious treatment parallel to hot compress and topical diclofenac.

    Full Text Available Compression is the most effective treatment to promote skin ulcer healing, although there are as many different methods of performing a leg compression as the number of phlebologists, each one having personal tricks, solutions, habits. Conversely, though dressings may be done in different ways, none is considered the standard solution. We asked few (18 questions to physicians involved in this field, in Italy and abroad, looking for some common feature. The analysis of 100 replies indicated the average treatment: compression made by multilayer bandage when edema is present, knee long stocking when edema is removed, mostly based on patient’s agreement. Escharectomy should be done when ulcer bed is covered by necrotic tissue. Advanced wound care is used, with dressing changed several times a week. For highly exuding ulcers, a specific dressing is used or frequent changing is performed. The treatment in early stage of disease is done by the physician while subsequently the dressings may be performed by the patient himself, nurses or doctors. Usually no medical treatments are associated. The cost of a single dressing is often lower than 10 Euro, without any reimbursement. The compression devices aren’t reimbursed as well. The expected compression pressure is 30/40 mm Hg. Daytime compression is not reduced at night-time. The patient is always invited to walk. The same compression is used if the ABPI is <1. However the survey shows that several variations in the cookbook may occur, sometimes even contradictory.

    This systematic review compared the relative efficacy of 5-fluorouracil 0.5% in salicylic acid 10% (5-FU/SA), ingenol mebutate (IMB) and imiquimod 2.5%/3.75% (IMI) for actinic keratosis on the face, forehead or scalp. Only 11 publications, relating to 7 randomised controlled trials, met inclusion criteria and it was only possible to compare the effect of all 3 treatments on complete clinical clearance, and the effect of 5-FU/SA and IMB on actinic keratosis recurrence rate. Despite a higher vehicle response rate for 5-FU/SA, complete clinical clearance was higher than IMB and IMI (55.4, 42.2, and 25.0-30.6/34.0-35.6%, [corrected] respectively). 5-FU/SA was also associated with lower actinic keratosis recurrence rate than IMB at 12 months post-treatment (32.7 vs. 53.9%). Although qualitative assessment suggested a numerical advantage of 5-FU/SA over IMB and IMI in terms of complete clinical clearance and sustained clearance, clinical data from longer term trials, with comparable outcome measures, are required to corroborate these findings.

  12. Before hierarchy: the rise and fall of Stephen Jay Gould's first macroevolutionary synthesis.

    Dresow, Max W

    2017-06-01

    Few of Stephen Jay Gould's accomplishments in evolutionary biology have received more attention than his hierarchical theory of evolution, which postulates a causal discontinuity between micro- and macroevolutionary events. But Gould's hierarchical theory was his second attempt to supply a theoretical framework for macroevolutionary studies-and one he did not inaugurate until the mid-1970s. In this paper, I examine Gould's first attempt: a proposed fusion of theoretical morphology, multivariate biometry and the experimental study of adaptation in fossils. This early "macroevolutionary synthesis" was predicated on the notion that parallelism and convergence dominate the history of higher taxa, and moreover, that they can be explained in terms of adaptation leading to mechanical improvement. In this paper, I explore the origins and contents of Gould's first macroevolutionary synthesis, as well as the reasons for its downfall. In addition, I consider how various developments during the mid-1970s led Gould to identify hierarchy and constraint as the leading themes of macroevolutionary studies-and adaptation as a macroevolutionary red herring.

  13. Treatment with silver nitrate versus topical steroid treatment for umbilical granuloma: A non-inferiority randomized control trial.

    Directory of Open Access Journals (Sweden)

    Chikako Ogawa

    Full Text Available The aim of this prospective multicenter randomized controlled trial was to compare the efficacy of silver nitrate cauterization against that of topical steroid ointment in the treatment of neonatal umbilical granuloma.An open-label, non-inferiority randomized controlled trial was conducted from January 2013 to January 2016. The primary endpoint for the silver nitrate cauterization and topical steroid ointment groups was the healing rate after 2 weeks of treatment, applying a non-inferiority margin of 10%. The healing rate was evaluated until completion of 3 weeks of treatment.Participants comprised 207 neonates with newly diagnosed umbilical granuloma, randomized to receive silver nitrate cauterization (n = 104 or topical steroid ointment (n = 103. Healing rates after 2 weeks of treatment were 87.5% (91/104 in the silver nitrate cauterization and 82% (82/100 in the topical steroid ointment group group. The difference between groups was -5.5% (95% confidence interval, -19.1%, 8.4%, indicating that the non-inferiority criterion was not met. After 3 weeks of treatment, the healing rate with topical steroid ointment treatment was almost identical to that of silver nitrate cauterization (94/104 [90.4%] vs. 91/100 [91.0%]; 0.6% [-13.2 to 14.3]. No major complications occurred in either group.This study did not establish non-inferiority of topical steroid ointment treatment relative to silver nitrate cauterization, presumably due to lower healing rates than expected leading to an underpowered trial. However, considering that silver nitrate cauterization carries a distinct risk of chemical burns and that the overall efficacy of topical steroid ointment treatment is similar to that of silver nitrate cauterization, topical steroid ointment might be considered as a good alternative in the treatment of neonatal umbilical granuloma due to its safety and simplicity. To clarify non-inferiority, a larger study is needed.

  14. Species coexistence: macroevolutionary relationships and the contingency of historical interactions.

    Evolutionary biologists since Darwin have hypothesized that closely related species compete more intensely and are therefore less likely to coexist. However, recent theory posits that species diverge in two ways: either through the evolution of 'stabilizing differences' that promote coexistence by causing individuals to compete more strongly with conspecifics than individuals of other species, or through the evolution of 'fitness differences' that cause species to differ in competitive ability and lead to exclusion of the weaker competitor. We tested macroevolutionary patterns of divergence by competing pairs of annual plant species that differ in their phylogenetic relationships, and in whether they have historically occurred in the same region or different regions (sympatric versus allopatric occurrence). For sympatrically occurring species pairs, stabilizing differences rapidly increased with phylogenetic distance. However, fitness differences also increased with phylogenetic distance, resulting in coexistence outcomes that were unpredictable based on phylogenetic relationships. For allopatric species, stabilizing differences showed no trend with phylogenetic distance, whereas fitness differences increased, causing coexistence to become less likely among distant relatives. Our results illustrate the role of species' historical interactions in shaping how phylogenetic relationships structure competitive dynamics, and offer an explanation for the evolution of invasion potential of non-native species. © 2016 The Author(s).

  15. Molecular evolution across the Asteraceae: micro- and macroevolutionary processes.

    Kane, Nolan C; Barker, Michael S; Zhan, Shing H; Rieseberg, Loren H

    2011-12-01

    The Asteraceae (Compositae) is a large family of over 20,000 wild, weedy, and domesticated species that comprise approximately 10% of all angiosperms, including annual and perennial herbs, shrubs and trees, and species on every continent except Antarctica. As a result, the Asteraceae provide a unique opportunity to understand the evolutionary genomics of lineage radiation and diversification at numerous phylogenetic scales. Using publicly available expressed sequence tags from 22 species representing four of the major Asteraceae lineages, we assessed neutral and nonneutral evolutionary processes across this diverse plant family. We used bioinformatic tools to identify candidate genes under selection in each species. Evolution at silent and coding sites were assessed for different Gene Ontology functional categories to compare rates of evolution over both short and long evolutionary timescales. Our results indicate that patterns of molecular change across the family are surprisingly consistent on a macroevolutionary timescale and much more so more than would be predicted from the analysis of one (or many) examples of microevolution. These analyses also point to particular classes of genes that may be crucial in shaping the radiation of this diverse plant family. Similar analyses of nuclear and chloroplast genes in six other plant families confirm that many of these patterns are common features of the plant kingdom.

    This article discusses current practice in the treatment of conjunctivitis and how the use of topical moxifloxacin can increase therapeutic effectiveness, reduce treatment failures and, consequently, be cost effective and reduce the societal burden of the disorder. Current practice and effectiveness data were derived from the literature. Data on healthcare utilization as a result of treatment failure were collected by survey and the cost of treatment was defined using national costings. A decision-analytic model to assess cost effectiveness was developed and the impact on the healthcare budget was calculated to define the health economic impact. Bacterial conjunctivitis represents a significant health problem and accounts for an estimated 1-1.5% of primary-care consultations. The disorder is highly contagious and causes a substantial healthcare and societal burden. Bacterial conjunctivitis is generally self-limiting, resolving within 1-2 weeks. However, the use of antibacterials significantly improves clinical and microbiological remission, shortens symptom duration, and enables more effective use of healthcare resources, compared with placebo. From a health economic perspective this benefits the healthcare system and society, since fewer healthcare resources are needed and the adult affected, or the parent/caregiver of the child affected, can return to full work capacity sooner, reducing loss of productivity. Treatment strategies vary significantly between countries. Most patients are first seen in primary care, where 'wait-and-see', lubrification and antiseptic or antibacterial treatment is provided. In Europe, when antibacterials are prescribed most general practitioners (GPs) prescribe a broad-spectrum topical antibacterial. The most commonly used drugs are chloramphenicol and fusidic acid, with fluoroquinolones rarely reported as first-line treatment by GPs. At the specialist (ophthalmologist) level, or for second-line treatment at the GP level, topical

    Atopic dermatitis (AD) is a chronic or chronically relapsing inflammatory skin condition that primarily affects children. Topical corticosteroids have been the mainstay of treatment since the late 1950s. While providing excellent short-term efficacy, topical corticosteroid usage is limited by potential adverse effects, including impairment of the function and viability of Langerhans cells/dendritic cells. The recently introduced topical calcineurin inhibitors pimecrolimus cream 1% (Elidel) and tacrolimus ointment 0.03 and 0.1% (Protopic) exhibit a more selective mechanism of action and do not affect Langerhans cells/dendritic cells. For the immune system of young children 'learning' to mount a balanced Th1/Th2 response, this selective effect has particular benefits. In clinical experience, topical calcineurin inhibitors have been shown to be a safe and effective alternative to topical corticosteroids in almost 7 million patients (>5 million on pimecrolimus; >1.7 million on tacrolimus). Topical pimecrolimus is primarily used in children with mild and moderate AD, whereas tacrolimus is used preferentially in more severe cases. None of the topical calcineurin inhibitors have been associated with systemic immunosuppression-related malignancies known to occur following long-term sustained systemic immunosuppression with oral immunosuppressants (e.g., tacrolimus, cyclosporine A, and corticosteroids) in transplant patients. Preclinical and clinical data suggest a greater skin selectivity and larger safety margin for topical pimecrolimus. (c) 2005 S. Karger AG, Basel

    Full Text Available Treatment of wet age-related macular degeneration (AMD requires frequent intravitreal injections of anti-VEGF agents, sometimes on monthly basis during a long period of time. Endophthalmitis is a rare but extremely severe complication of intravitreal injections. As it has been proven before, the flora from the conjunctival surface is the main source for endophthalmitis. Using Povidone-iodine solution (Betadine10 % Povidone-iodine, EGIS PHARMACEUTICALS is the only way to prevent endophthalmitis. The efficacy of it was proven by numerous studies. No evidence exists that topical antibiotiotics prior and after injections could be effective for prevention of endophthalmitis. Purpose: To study the advisability of topical antibiotic application before intravitreal injection. Materials and methods: Under investigation, there were 25 eyes of 25 patients with wet AMD treated by anti-VEGF intravitreal injections. All patients used topical antibiotics 3 days before injection. Conjunctival culture from injection eye was collected three times: before topical antibiotic use; after topical antibiotic use, and after Betadine 5 % application. Results: The rates of Staphylococcus epidermidis before and after topical antibiotic use were approximately equal. However there was no Staphylococcus epidermidis found after Betadine 5 % application. Conclusion: Our study showed the effectiveness of Betadine 5 % solution in conjunctival flora reduction. Use of topical antibiotics 3 days prior intravitreal injections is not effective. Key words: age-related macular degeneration; endophthalmitis; intravitreal injection; topical antibiotics; endophthalmitis prevention.

    Serum thymus and activation-regulated chemokine (TARC) levels are associated with the disease activity of patients with atopic dermatitis (AD) and sensitively reflect short-term changes in skin conditions. The main treatment for AD is topical agent application. This study investigated the relationship between serum TARC levels and the dosage of topical agents, including corticosteroids and/or tacrolimus, in patients with AD. The serum TARC levels of 56 AD patients and the amounts of topical agents prescribed to them were investigated retrospectively. The weekly reduction in serum TARC levels and weekly dosage of topical agents among AD patients were compared and their associations were evaluated. The dosage of topical agents was closely related to serum TARC levels. One gram of strong rank steroid or the equivalent amount of steroid/tacrolimus is required to reduce serum TARC levels by 9.94 pg/mL weekly in moderate to severe AD patients. Higher initial TARC levels require more topical agent, which results in a more rapid decrease in TARC levels. The serum TARC levels and eosinophil numbers in peripheral blood are significantly correlated. Serum TARC level improvement and topical agent dosage are strongly correlated. TARC and eosinophil numbers are significantly correlated, but the wider range of TARC levels seems to be clinically more useful for monitoring AD severity. The serum TARC level is a very sensitive biomarker for monitoring the severity and treatment response in AD.

    Topical corticosteroids or dietary elimination are recommended as first-line therapies for eosinophilic esophagitis, but data to directly compare these therapies are scant. We performed a cost utility comparison of topical corticosteroids and the 6-food elimination diet (SFED) in treatment of eosinophilic esophagitis, from the payer perspective. We used a modified Markov model based on current clinical guidelines, in which transition between states depended on histologic response simulated at the individual cohort-member level. Simulation parameters were defined by systematic review and meta-analysis to determine the base-case estimates and bounds of uncertainty for sensitivity analysis. Meta-regression models included adjustment for differences in study and cohort characteristics. In the base-case scenario, topical fluticasone was about as effective as SFED but more expensive at a 5-year time horizon ($9261.58 vs $5719.72 per person). SFED was more effective and less expensive than topical fluticasone and topical budesonide in the base-case scenario. Probabilistic sensitivity analysis revealed little uncertainty in relative treatment effectiveness. There was somewhat greater uncertainty in the relative cost of treatments; most simulations found SFED to be less expensive. In a cost utility analysis comparing topical corticosteroids and SFED for first-line treatment of eosinophilic esophagitis, the therapies were similar in effectiveness. SFED was on average less expensive, and more cost effective in most simulations, than topical budesonide and topical fluticasone, from a payer perspective and not accounting for patient-level costs or quality of life.

    Erythema-directed digital photography is a novel method for evaluating the efficacy and tolerability of topical acne treatments. Here, we describe three case reports in which erythema-directed digital photography was used to evaluate acne before and after up to 12 weeks of treatment with clindamycin 1%/tretinoin 0.025% (Clin-RA). Erythema-directed digital photography was used to evaluate acne in three patients with mild-to-moderate facial acne, two of whom had refused to continue previous topical acne treatment (benzoyl peroxide 5% and clindamycin 1%/benzoyl peroxide 5%) due to persistent irritation. Acne lesions and erythema were evaluated using standard clinical photography and erythema-directed digital photography (VISIA-CR ™ system) before and after 8-12 weeks of treatment with Clin-RA. Erythema-directed digital photography revealed background erythema from previous topical acne treatments that was not evident from standard clinical photographs and allowed a better visualization of both inflammatory and non-inflammatory lesions. In all patients, there was a clear improvement in background erythema and a reduction in acne lesions following treatment with Clin-RA. This study has demonstrated for the first time that erythema-directed digital photography can enhance the evaluation of the efficacy and tolerability of topical acne treatments. These cases show that Clin-RA was associated with improved efficacy and tolerability vs previous treatments with topical monotherapy (benzoyl peroxide 5%) or a topical fixed-dose combination (clindamycin 1%/benzoyl peroxide 5%). © 2018 The Authors.

    To compare oil of evening primrose (OEP) and topical nonsteroidal anti-inflammatory (NSAIDs) with respect to safety, effectiveness, rapidity of response, cost effectiveness and acceptability in the treatment of breast pain. An open, non-randomised, comparative study of topical (NSAI) gel versus OEP was carried out, over a period of one year. Fifty female patients attending the outpatient department with moderate to severe breast pain were given one of the two agents alternatively, after selection. Results showed that out of 25 patients treated with OEP, 64% had a clinically significant response after three months of treatment, compared with 92% with topical NSAIDs. Only one patient (4%) had side effects with OEP, while no patient had side effects with topical NSAIDs. Twenty per cent and seventy per cent showed acceptability as far as costs were concerned and mode of administration respectively, with OEP. The acceptability rate was 68% and 96% respectively, with topical NSAIDs. This study has shown topical NSAIDs to be safe, effective, rapid and acceptable mode of treatment for cyclical and non-cyclical mastalgia.

    Scarring from bacterial keratitis remains a leading cause of visual loss. To determine whether topical corticosteroids are beneficial as an adjunctive therapy for bacterial keratitis if given early in the course of infection. The Steroids for Corneal Ulcers Trial (SCUT) was a randomized, double-masked, placebo-controlled trial that overall found no effect of adding topical corticosteroids to topical moxifloxacin hydrochloride in bacterial keratitis. Here, we assess the timing of administration of corticosteroids in a subgroup analysis of the SCUT. We define earlier administration of corticosteroids (vs placebo) as addition after 2 to 3 days of topical antibiotics and later as addition after 4 or more days of topical antibiotics. We assess the effect of topical corticosteroids (vs placebo) on 3-month best spectacle-corrected visual acuity in patients who received corticosteroids or placebo earlier vs later. Further analyses were performed for subgroups of patients with non-Nocardia keratitis and those with no topical antibiotic use before enrollment. Patients treated with topical corticosteroids as adjunctive therapy within 2 to 3 days of antibiotic therapy had approximately 1-line better visual acuity at 3 months than did those given placebo (-0.11 logMAR; 95% CI, -0.20 to -0.02 logMAR; P = .01). In patients who had 4 or more days of antibiotic therapy before corticosteroid treatment, the effect was not significant; patients given corticosteroids had 1-line worse visual acuity at 3 months compared with those in the placebo group (0.10 logMAR; 95% CI, -0.02 to 0.23 logMAR; P = .14). Patients with non-Nocardia keratitis and those having no topical antibiotic use before the SCUT enrollment showed significant improvement in best spectacle-corrected visual acuity at 3 months if corticosteroids were administered earlier rather than later. There may be a benefit with adjunctive topical corticosteroids if application occurs earlier in the course of bacterial

  4. Macroevolutionary patterns of sexual size dimorphism in copepods

    Major theories compete to explain the macroevolutionary trends observed in sexual size dimorphism (SSD) in animals. Quantitative genetic theory suggests that the sex under historically stronger directional selection will exhibit greater interspecific variance in size, with covariation between allometric slopes (male to female size) and the strength of SSD across clades. Rensch's rule (RR) also suggests a correlation, but one in which males are always the more size variant sex. Examining free-living pelagic and parasitic Copepoda, we test these competing predictions. Females are commonly the larger sex in copepod species. Comparing clades that vary by four orders of magnitude in their degree of dimorphism, we show that isometry is widespread. As such we find no support for either RR or for covariation between allometry and SSD. Our results suggest that selection on both sexes has been equally important. We next test the prediction that variation in the degree of SSD is related to the adult sex ratio. As males become relatively less abundant, it has been hypothesized that this will lead to a reduction in both inter-male competition and male size. However, the lack of such a correlation across diverse free-living pelagic families of copepods provides no support for this hypothesis. By comparison, in sea lice of the family Caligidae, there is some qualitative support of the hypothesis, males may suffer elevated mortality when they leave the host and rove for sedentary females, and their female-biased SSD is greater than in many free-living families. However, other parasitic copepods which do not appear to have obvious differences in sex-based mate searching risks also show similar or even more extreme SSD, therefore suggesting other factors can drive the observed extremes.

    This article is a report of a study evaluating changes in health status before and after topical ginger treatment for adults with moderate to severe osteoarthritis. In 2011, 20 adults with chronic osteoarthritis were randomly assigned to one of two groups for 7 consecutive days of topical ginger treatment by trained nurses: Group 1 received a manually prepared ginger compress and Group 2 a standardized ginger patch. Participants had the option to continue self-treatment using the ginger patch for a further 24 weeks. A brief arthritis health questionnaire was completed weekly for 3 weeks and 4 weekly for 24 weeks. The mean scores for Group 1 and Group 2 show a notable decline following 1-week topical ginger treatment; scores in pain, fatigue, global effect, and functional status reduced by 48%, 49%, 40%, and 31%, respectively, whereas health satisfaction improved from 80% dissatisfied to 70% satisfied. Scores for all participants in all five domains progressively reduced over the following 24 weeks of self-treatment. Topical ginger treatment has the potential to relieve symptoms, improve the overall health, and increase independence of people with chronic osteoarthritis. © The Author(s) 2013.

    The immunopathogenic mechanisms of dry eye disease (DED), one of the most common ophthalmic conditions, is incompletely understood. Data from this prospective, double-masked, randomized trial demonstrate that targeting interleukin 1 (IL-1) by topical application of an IL-1 antagonist is efficacious in significantly reducing DED-related patient symptoms and corneal epitheliopathy. To evaluate the safety and efficacy of treatment with the topical IL-1 receptor antagonist anakinra (Kineret; Amgen Inc) in patients having DED associated with meibomian gland dysfunction. Prospective phase 1/2, randomized, double-masked, vehicle-controlled clinical trial. Seventy-five patients with refractory DED. Participants were randomized to receive treatment with topical anakinra, 2.5% (n = 30), anakinra, 5% (n = 15), or vehicle (1% carboxymethylcellulose) (n = 30) 3 times daily for 12 weeks. Primary outcomes were corneal fluorescein staining (CFS), complete bilateral CFS clearance, dry eye-related symptoms as measured by the Ocular Surface Disease Index, tear film breakup time, and meibomian gland secretion quality. Topical anakinra was well tolerated compared with vehicle, with no reports of serious adverse reactions attributable to the therapy. After 12 weeks of therapy, participants treated with anakinra, 2.5%, achieved a 46% reduction in their mean CFS score (P = .12 compared with vehicle and P treatment with anakinra, 2.5%, and treatment with anakinra, 5%, led to significant reductions in symptoms of 30% and 35%, respectively (P = .02 and P = .01, respectively, compared with vehicle); treatment with vehicle led to a 5% reduction in symptoms. Treatment with topical anakinra, 2.5%, for 12 weeks was safe and significantly reduced symptoms and corneal epitheliopathy in patients with DED. These data suggest that the use of an IL-1 antagonist may have a role as a novel therapeutic option for patients with DED. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00681109.

  8. Tempo and mode in the macroevolutionary reconstruction of Darwinism.

    Gould, S J

    1994-01-01

    Among the several central meanings of Darwinism, his version of Lyellian uniformitarianism--the extrapolationist commitment to viewing causes of small-scale, observable change in modern populations as the complete source, by smooth extension through geological time, of all magnitudes and sequences in evolution--has most contributed to the causal hegemony of microevolution and the assumption that paleontology can document the contingent history of life but cannot act as a domain of novel evolutionary theory. G. G. Simpson tried to combat this view of paleontology as theoretically inert in his classic work, Tempo and Mode in Evolution (1944), with a brilliant argument that the two subjects of his title fall into a unique paleontological domain and that modes (processes and causes) can be inferred from the quantitative study of tempos (pattern). Nonetheless, Simpson did not cash out his insight to paleontology's theoretical benefit because he followed the strict doctrine of the Modern Synthesis. He studied his domain of potential theory and concluded that no actual theory could be found--and that a full account of causes could therefore be located in the microevolutionary realm after all. I argue that Simpson was unduly pessimistic and that modernism's belief in reductionistic unification (the conventional view of Western intellectuals from the 1920s to the 1950s) needs to be supplanted by a postmodernist commitment to pluralism and multiple levels of causation. Macro- and microevolution should not be viewed as opposed, but as truly complementary. I describe the two major domains where a helpful macroevolutionary theory may be sought--unsmooth causal boundaries between levels (as illustrated by punctuated equilibrium and mass extinction) and hierarchical expansion of the theory of natural selection to levels both below (gene and cell-line) and above organisms (demes, species, and clades). Problems remain in operationally defining selection at non-organismic levels

    Full Text Available Introduction: Otorrhea and granulation tissue in Canal Wall Down mastoidectomy (CWD is the common problem in cholesteatoma removal and leads to many discomfort for both the patient and the physician. The main objective in CWD is creating the dry cavity, so the topical antibiotic and acetic acid in variable saturations are used for this purpose. In this study we evaluate the effectiveness of topical MMC and chemical cautery by acetic acid.   Materials and Methods: Study population consists of 50 patients with cholesteatoma whom underwent CWD. All patient allocated randomly in two study groups, MMC and acetic acid. After 3 weeks, the first visit is planned, extension of granulation tissue and dryness of cavity are evaluated and topical drugs are used in blind fashion. MMC in 4% and acetic acid in 12.5% saturation are applied. Other visits are completed at next month and 3 months later.   Results: Both methods are effective in treatment of granulation tissue. In each group both treatment were effective too but MMC was more effective than acid acetic in the treatment of granulation tissue after 4 weeks.   Conclusion: Based on our findings, it is clear that topical MMC is very effective in the treatment of granulation tissue and in CWD. It results in dry cavity much better than acetic acid without any complication.

    Topical therapy is important in the treatment of actinic keratosis, but guidance for improving adherence/persistence during topical therapy is still lacking. To utilize expert consensus to generate a list of recommendations to improve real-world efficacy when prescribing topical therapy for actinic keratosis. An expert panel of eight dermatologists was convened to generate recommendations based on facilitated discussion and consensus generation using a modified Delphi session. The recommendations were ratified with the expert panel. Facilitated discussion generated 31 issues within five themes, which were prioritized using expert voting. Consensus was achieved on the importance of short and simple treatment regimens for maximizing patient compliance, physician awareness of the progression of actinic keratosis to squamous cell carcinoma, provision of appropriate patient information, and the use of effective communication strategies to educate physicians about actinic keratosis. Based on these key findings, eight recommendations were generated. The recommendations will assist physicians when prescribing topical actinic keratosis therapy. Further research should focus on the types of patient outcomes that are influenced by the characteristics of topical field therapy. © 2015 The Authors.

    2014-08-01

    To evaluate preoperative and postoperative dry eye and the effect of cyclosporine A treatment in patients screened for corneal refractive surgery and treated with photorefractive keratectomy (PRK) or LASIK. A consecutive case series of 1,056 patients screened for corneal refractive surgery from 2007 to 2012 was retrospectively analyzed. The level of preoperative and postoperative dry eye and the responsiveness to topical cyclosporine A treatment were assessed. One eye of each patient was randomly selected. A total of 642 eyes progressed to surgery: 524 (81.6%) and 118 (18.4%) underwent LASIK and PRK, respectively. Of 81 (7.7%) diagnosed as having dry eye, 55 were deemed potential candidates and optimized for refractive surgery. Thirty-seven patients with moderate dry eye were treated with topical cyclosporine A prior to surgery (mean duration: 3.2 ± 2.1 months; range: 1 to 12 months). After cyclosporine A treatment, 28 (75.7%) eyes underwent LASIK, 4 (10.8%) eyes underwent PRK, and 5 (13.5%) eyes were not operated on due to failed treatment of dry eye. Postoperative refractive surgery-induced neurotrophic epitheliopathy (LINE in LASIK) was noted in 132 (27.3%) and 12 (11.1%) eyes that underwent LASIK and PRK, respectively. Topical cyclosporine A was prescribed in 79 LASIK-induced and 3 PRK-induced dry eyes. After 12 months or more of cyclosporine A treatment, 5 (6.1%) eyes continued to have dry eye symptoms or signs. Topical cyclosporine A treatment is effective therapy for optimizing patients for refractive surgery and treatment of new onset or worsened dry eye after surgery. Copyright 2014, SLACK Incorporated.

    Abstract Background: Skin laxity and cellulite on the buttocks and thighs are two common cosmetic concerns. Skin tightening with radiofrequency (RF) devices has become increasingly popular. The purpose of this study is to evaluate the efficacy and safety of a topical skin laxity tightening agent when used in combination with an RF device. A double-blinded, randomized clinical trial enrolled twenty females with mild-to-moderate skin laxity on the posterior thighs/buttocks. Each subject underwent two monthly treatments with an RF source (Alma Accent) to both legs. Subjects were then randomized to apply a topical agent (Skinceuticals Body Tightening Concentrate) twice daily to only one designated thigh/buttock throughout the eight-week duration of the study. All subjects were evaluated for improvement in lifting, skin tone, radiance, firmness/tightness, skin texture, and overall appearance based on photographic evaluation by blinded investigators at 12 weeks following the final RF treatment. A statistically significant improvement was found in the overall appearance on both sides treated with the RF device when compared to baseline. However, the area treated with the topical agent showed a statistically significantly greater degree of improvement than the side where no topical agent was applied. No adverse effects were reported. The use of a novel skin tightening agent used after RF procedures is both safe and effective for treatment of skin laxity on the buttocks and thighs. Combined therapy leads to a better result.

    Continuous positive airways pressure (CPAP) for treatment of obstructive sleep apnea (OSA) can produce troublesome nasal symptoms (i.e. congestion, rhinorrhea) that may reduce the compliance of CPAP. Topical nasal steroids are often prescribed to reduce these side effects, although scientific data are scarce supporting any benefits of this treatment for CPAP-induced nasal side effects. To study whether a topical nasal steroid can reduce CPAP-induced nasal symptoms and improve CPAP adherence during the initial phase of OSA treatment. A randomized, double-blinded, placebo-controlled study with fluticasone propionate 100 μg/nasal cavity twice daily Treatment was started 10 days prior to and continued throughout the first 4 weeks of CPAP. 63 patients who were selected for CPAP treatment participated. Nasal symptoms were recorded, nasal patency was assessed and lung function was measured with a peak flow meter. The patients' adherence to CPAP was recorded by the CPAP device. Total nasal symptoms increased from baseline to 4 wks after CPAP use for both nasal treatments (p < 0.05). No differences in total nasal symptoms between treatments were seen (p = 1), and no differences in nasal peak flow values after treatment were seen (p = 0.11). Moreover, there were no differences in CPAP use between the treatments. Fluticasone propionate as a nasal topical steroid does not reduce CPAP-induced unwanted nasal side effects, and has no beneficial effect on CPAP compliance during the first four weeks of treatment in unselected patients with OSAS.

    The most frequent symptom of craniomandibular dysfunction is pain in the preauricular area or in the temporo-mandibular joint, usually localized at the level of the masticatory musculature. Patients sometimes also complain of reflect otalgia, headaches and facial pain. Osteoarthrosis is a frequent degenerative debilitating chronic disorder that can affect the temporomandibular joint. It causes pain and articular rigidity, a reduction in mobility, and radiological alterations are visible in stratigraphy. The aim of this study was to compare the efficacy of a topically applied non-steroid anti-inflammatory drug that has recently become commercially available (diclofenac sodium in a patented carrier containing dimethyl sulfoxide, that favours transcutaneous absorption) which is commonly used to alleviate pain in knee or elbow joints, versus oral diclofenac, in the treatment of symptoms of temporomandibular joint dysfunction. Dysfunction of the temporomandibular joint was diagnosed in 36 adult patients. The patients were randomized in two age- and gender -matched groups. Group A (18 patients) received oral diclofenac sodium administered after a meal in 50-mg tablets twice a day for 14 days. Group B (18 patients) received 16 mg/ml topical diclofenac (diclofenac topical solution, 10 drops 4 times a day for 14 days). All patients completed a questionnaire at the start and end of therapy. Patients were asked to quantify on a graded visual analogue scale and to reply to questions about the pain and tenderness of the temporomandibular joint and the functional limitation of mouth opening. Patients were also requested to report side-effects of the treatment. All patients showed relief from pain after treatment: the difference between the two groups was not significant (p > 0.05). Post-treatment, 16 patients of group A had epigastralgic symptoms. Three patients treated with topical diclofenac showed a modest irritation of the temporomandibular joint region, and disappeared

    Medication nonadherence is a major impediment to the management of many health conditions. A better understanding of the factors underlying noncompliance to treatment may help health professionals to address it. Patients use peer-to-peer virtual communities and social media to share their experiences regarding their treatments and diseases. Using topic models makes it possible to model themes present in a collection of posts, thus to identify cases of noncompliance. The aim of this study was to detect messages describing patients' noncompliant behaviors associated with a drug of interest. Thus, the objective was the clustering of posts featuring a homogeneous vocabulary related to nonadherent attitudes. We focused on escitalopram and aripiprazole used to treat depression and psychotic conditions, respectively. We implemented a probabilistic topic model to identify the topics that occurred in a corpus of messages mentioning these drugs, posted from 2004 to 2013 on three of the most popular French forums. Data were collected using a Web crawler designed by Kappa Santé as part of the Detec't project to analyze social media for drug safety. Several topics were related to noncompliance to treatment. Starting from a corpus of 3650 posts related to an antidepressant drug (escitalopram) and 2164 posts related to an antipsychotic drug (aripiprazole), the use of latent Dirichlet allocation allowed us to model several themes, including interruptions of treatment and changes in dosage. The topic model approach detected cases of noncompliance behaviors with a recall of 98.5% (272/276) and a precision of 32.6% (272/844). Topic models enabled us to explore patients' discussions on community websites and to identify posts related with noncompliant behaviors. After a manual review of the messages in the noncompliance topics, we found that noncompliance to treatment was present in 6.17% (276/4469) of the posts. ©Redhouane Abdellaoui, Pierre Foulquié, Nathalie Texier, Carole

    Ectodermal dysplasia is a clinically and genetically heterogeneous group of inherited disorders characterized by abnormal development of two or more of the following ectodermal-derived structures: hair, teeth, nails and sweat glands. The hair is the most frequently affected structure. Hair shaft abnormalities are of great concern to these patients, but no effective treatments are available. We describe three girls with congenital hypotrichosis (9, 5 and 6 years old) caused by ectodermal dysplasia treated with topical cetirizine solution (2 mL. once daily) and oral vitamin D supplementation (1000 IU daily). After 6 months of treatment, the density of hair on the scalp increased in all patients. The vellus hair was replaced by terminal hair. Hair regrowth was evaluated both from the clinical and trichoscopic point of view. We propose a combination of topical cetirizine and oral vitamin D as a rational treatment of choice in congenital hypotrichosis caused by ectodermal dysplasia. © 2016 European Academy of Dermatology and Venereology.

    Ligneous conjunctivitis (LC) is a rare form of bilateral chronic recurrent disease in which thick membranes form on the palpebral conjunctiva and other mucosal sites. We report the clinical features and describe the management of two cases. Case 1 was an 8-month-old patient with bilateral membranous conjunctivitis. Case 2 was a 5-year-old patient with unilateral membranous conjunctivitis, esotropia, mechanical ptosis and complicated cataract, and had been treated with a number of medications. Histological investigation of the membrane in both cases showed LC. Treatments with amniotic membrane transplantation and institution of topical cyclosporine have shown good response. There has been complete resolution of the membranes with no recurrence at the end of 40- and 28-month follow-ups, respectively. No treatment related side effects were seen. Thus, it appears that amniotic membrane transplantation and topical cyclosporine are effective alternatives for the treatment of LC. PMID:23202401

Psoriatic patients have different attitudes toward their condition. Topical medications are essential for the treatment of psoriasis, but the majority of patients do not adhere to these therapies. Objective: The history of treatment success or failure seems to influence patient attitude toward topical therapy. Therefore, it is important to understand the psychological, experiential, and motivational aspects that could be critical for treatment adherence, and to describe the different attitudes toward topical treatment. Furthermore, the physician–patient relationship and the willingness to trust the dermatologist may have a substantial role in encouraging or discouraging patients’ attitudes toward topical therapy. Methods: A survey was designed to collect aspects that could be relevant to understanding different patient attitudes toward psoriasis and its treatments. A total of 495 self-administered questionnaires compiled by psoriatic patients were analyzed from 20 Italian specialized hospital centers in order to provide a nationwide picture. Results: Psoriatic patients have different perceptions and experiences in relation to their condition: half of them consider psoriasis as a disease, while the other half consider psoriasis as a disorder or a nuisance. Topical therapy is the most widely used treatment, even though it is not considered the most effective one and often perceived to be cosmetic. The main findings are: 1

    Full Text Available Background: Topical anaesthetics are effective for patients undergoing superficial dermatological and laser procedures. Our objective was to compare the efficacy and patient preference of three commonly used topical anaesthetics: (2.5% lidocaine/2.5% prilocaine cream (EMLA ® , 4% tetracaine gel (Ametop TM and 4% liposomal lidocaine gel (LMX4 ® in patients undergoing laser procedures and skin microneedling. Settings and Design: This was a prospective, double-blind study of patients undergoing laser and skin microneedling procedures at a laser unit in a tertiary referral dermatology centre. Materials and Methods: All 29 patients had three topical anaesthetics applied under occlusion for 1 hour prior to the procedure, at different treatment sites within the same anatomical zone. A self-assessment numerical pain rating scale was given to each patient to rate the pain during the procedure and each patient was asked to specify their preferred choice of topical anaesthetic at the end of the procedure. Statistical Analysis: Parametric data (mean pain scores and frequency of topical anaesthetic agent of choice were compared using the paired samples t-test. A P-value of ≤0.05 was considered as statistically significant. Results and Conclusions: Patients reported a mean (±SD; 95% confidence interval pain score of 5 (±2.58; 3.66-6.46 with Ametop TM , 4.38 (±2.53; 2.64-4.89 with EMLA ® and 3.91 (±1.95; 2.65-4.76 with LMX4 ® . There was no statistically significant difference in pain scores between the different topical anaesthetics. The majority of patients preferred LMX4 ® as their choice of topical anaesthetic for dermatological laser and skin microneedling procedures.

    Patients with psoriasis often enquire about the use of numerous botanical therapeutics. It is important for dermatologists to be aware of the current evidence regarding these agents. We conducted a systematic literature search using the PubMed, MEDLINE, and EMBASE databases for controlled and uncontrolled clinical trials that assessed the use of topical botanical therapeutics for psoriasis. The search included the following keywords: 'psoriasis' and 'plant' or 'herbal' or 'botanical'. We also reviewed citations within articles to identify additional relevant sources. We then further refined the results by route of administration and the topical botanical agents are reviewed herein. A total of 27 controlled and uncontrolled clinical trials addressing the use of topical botanical agents for psoriasis were assessed in this review. We found that the most highly studied and most efficacious topical botanical therapeutics were Mahonia aquifolium, indigo naturalis, aloe vera, and, to a lesser degree, capsaicin. The most commonly reported adverse effects were local skin irritation, erythema, pruritus, burning, and pain. However, the overall evidence for these therapeutics remains limited in quantity and quality. The literature addresses a large number of studies in regard to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary before topical botanical agents can be consistently recommended to patients.

    Few studies have focused on therapeutic as well as side effects of tranexamic acid (TXA) as a topical drug compared to other topical drugs in treating melasma. The present study aimed to assess and compare the beneficial therapeutic effects and also side effects of local TXA in comparison with hydroquinone in treating women with melasma. This randomized double-blinded clinical trial was performed on 60 women who suffered from melasma and were referred to the skin disorders clinic at the Rasoul-e-Akram hospital in Tehran in 2015. The patients were then randomly assigned via computerized randomization to two groups: group A received TXA%5 (topically twice a day for 12 weeks in the location of the melasma) and group B (received hydroquinone 2% with the same treatment order). Prior to intervention and at 12 weeks after intervention, the intensity and extension of melasma were assessed based on the Melasma Area and Severity Index (MASI) scoring method. The mean MASI score in both treatment groups decreased considerably after completion of treatment and was not significant between the two groups. No side effects were detected in group A, but 10% of those in group B complained of drug-related side effects including erythema and skin irritation (p = 0.131). Regarding the level of patient satisfaction, the patients in group A had a significantly higher level of satisfaction level of 33.3% compared with 6.7% in group B (p = 0.015) (Fig. 9). Multivariate linear regression modeling with the presence of age, history of systemic disorder, drug history, and family history of melasma demonstrated no difference in the mean MASI between the two groups. Topical use of TXA significantly reduced both melanin level and MASI score. Given its high efficiency and low drug side effects, this regimen results in high patient satisfaction compared with topical hydroquinone. IRCT code: IRCT2016040627220N2.

    Full Text Available The variety and multiple dimensions of pain (acute/chronic, mild/moderate/severe, nociceptive/neuropathic requires different pharmacologic and non-pharmacologic treatments in certain patients. A lot of topical formulation, from various therapeutic classes have been proposed in order to decrease systemic exposure and to reduce the risks of adverse events. Topical as well as transdermal drug delivery systems are proposed as medicated plasters with: anesthetics (lidocaine, analgesic or nonsteroidal anti-inflamatory drugs (NSAIDs, alone or co-formulated. Capsaicin, salicylates, menthol and camphor represent the counterirritant class of topical analgesics used as patch active compounds. These compounds produce their analgesic effect by activating and desensitizing epidermal nociceptors. The most used topical treatment in order to decrease pain is the application of cold and heat patches - by acting directly on the affected tissue. In many cases there is a limited number of studies providing insufficient information to clinicians in order to evaluate the benefits of these products. This paper reviews the use and efficacy of available self-adhesing occlusive medicated plaster (pain patches that might represent an alternative option for the management of patient pain, specially in the case of musculoskeletal and neuropathic disorders.

    Male androgenetic alopecia (AGA) is a common hair problem. Serenoa repens extract has been shown to inhibit both types of 5-α reductase and, when taken orally, has been shown to increase hair growth in AGA patients. The aim of this study was to assess the efficacy of topical products containing S. repens extract for the treatment of male AGA. This was a pilot, prospective, open, within-subject comparison limited to 24 weeks using no placebo controls. In all, 50 male volunteers aged between 20 and 50 years received topical S. repens products for 24 weeks. The primary end-point was a hair count in an area of 2.54 cm(2) at week 24. Secondary end-points included hair restoration, investigators' photographic assessment, patients' evaluation and discovering adverse events. The average hair count and terminal hair count increased at weeks 12 and 24 compared to baseline. Some of these positive results levelled off at week 24, presumably because the concentrated topical product containing S. repens extract was stopped after 4 weeks. The patients were satisfied with the products and the side-effects were limited. The topical application of S. repens extract could be an alternative treatment in male pattern baldness in male patients who do not want or cannot tolerate the side-effects of standard medications, but the use of a concentrated S. repens product beyond 4 weeks may be necessary for sustained efficacy. © 2015 The Australasian College of Dermatologists.

    Minoxidil is one of the drugs approved for the treatment of androgenetic alopecia. This article presents a case of central serous chorioretinopathy after application of topical minoxidil solution. We examined a 37-year-old man who complained of a positive relative scotoma, metamorphopsia and impaired dark adaptation involving the right eye. The patient reported an 8 month history of daily topical use but denied previous treatment with other drugs. Dilated fundus examination of right eye revealed central swelling located over the macula. Optical coherence tomography showed the presence of subretinal fluid. Fluorescein angiography disclosed one focal hyperfluorescent spot in the foveal area with minimal pigmentary changes limitated to that area. The patient was diagnosed with central serous chorioretinopathy (CSC) potentially related to an 8 month topical minoxidil solution administration. One month after the drug was discontinued, normal findings were found upon reexamination. The patient reported no previous episode of CSC. Major systemic side effects from topical solution of minoxidil are rare. To our knowledge, this is the first reported case of a central serous chorioretinopathy associated with long-term use of this drug.

    Psoriasis has been considered as systemic disorder. Lipocalin-2 might be a link between psoriasis and its comorbidities. Aim of the study was to investigate the associations between serum lipocalin-2 levels and the disease activity, markers of inflammation or metabolic disturbances and changes after topical treatment in psoriatic patients. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were recruited. Blood samples were collected before and after 14 days of therapy. Serum lipocalin-2 concentrations were examined by enzyme-linked immunosorbent assay. The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and with effectiveness of topical treatment. Lipocalin-2 serum levels were significantly increased in psoriatic patients in comparison to the controls (p = 0.023). No significant correlations with indicators of inflammation, nor BMI or PASI were noted. A statistical association between lipocalin-2 and low-density lipoprotein-cholesterol was shown. After topical treatment serum lipocalin-2 level did not significantly change (p = 0.9), still remaining higher than in the controls, despite clinical improvement. Lipocalin-2 might be a marker of psoriasis and convey cardiovascular or metabolic risk in psoriatic patients, but may not be a reliable indicator of inflammation, severity of psoriasis nor efficacy of antipsoriatic treatment.

Methods: This is a retrospective case series of patients with cystoid macular edema managed with a topical combination of strong steroid (difluprednate, NSAID, and carbonic anhydrase inhibitor drops. The patients were followed with optical coherence tomography and fluorescein angiography. Results: In our six cases, resolution of the cystic edema with improvement in visual acuity was achieved with the use of a combination cocktail of drops. Leakage on fluorescein angiography and cystic edema on optical coherence tomography both responded to treatment with the topical cocktail of drops. Conclusion: A topical cocktail of strong steroid, NSAID, and carbonic anhydrase inhibitor drops are effective for managing cystoid macular edema. Further studies comparing this combination with more invasive treatments should be undertaken to determine the efficacy of this cocktail over other treatment options.

    Limited data is available for treatment of scald lesions in adults. The use of the biosynthetic matrix Biobrane ® has been suggested as treatment option with more benefits over topical dressings. Application of Biobrane ® in scalds in our center led to a perceived increase of infection, secondary deepening, surgery and length of stay. We therefore assessed the effect of different treatment options in adult scalds in our center. We performed a retrospective cohort study of adult patients that have been admitted with scalds in our center between 2011 and 2014. We assessed two groups, group 1 with Biobrane ® as initial treatment and group 2 with topical treatment using polyhexanid hydrogel and fatty gauze. Primary outcome variables were rate of secondary deepening, surgery, infection (defined as positive microbiological swabs and antibiotic treatment) and length of stay. Total body surface area (TBSA) as well as diabetes mellitus (DM), hypertension, smoking and alcohol consumption as potential confounders were included. A total of 52 patients were included in this study. 36 patients received treatment with Biobrane ® and 16 with ointment and fatty gauze. No significant differences were found for age and TBSA whereas gender ratio was different (25/11 male/female in group 1 vs 4/12 in group 2, p=0.003). Rate of secondary deepening, surgery, infection as well as days of hospital stay (DOHS) were comparable. Logistic and multilinear regression showed TBSA to be a predictive factor for infection (p=0.041), and TBSA and age for length of stay (age p=0.036; TBSA p=0.042) in group 1. The use of Biobrane ® in adult scald lesions is safe and non-inferior to topical treatment options. In elder patients and larger TBSA Biobrane ® may increase the risk of infection or a prolonged stay in hospital. Level 3 - retrospective cohort study. Copyright © 2016 Elsevier Ltd and ISBI.

    This randomized, double-blind, placebo-controlled crossover study assessed the efficacy of topical tocopherol acetate compared with placebo in easing oral discomfort in patients with reticular oral lichen planus (ROLP). Thirty-four patients with clinically diagnosed and histologically confirmed ROLP were randomly assigned to two groups, which received first one of two treatments (treatment 1 or 2) for a month, then the other (treatment 2 or 1) for another month, with a two-week washout between them. One treatment contained tocopherol acetate and the other only liquid paraffin. The primary outcome was less discomfort, measured on a visual analog scale (VAS). Secondary outcomes were as follows: length of striae measured and photographed at each follow-up; surface area of lesions; and a modified Thongprasom score. No statistically significant differences emerged between the two treatments (1 vs 2) in terms of VAS scores (P > 0.05; 0.8624) or length of striae (P = 0.0883). Significant differences were seen for surface area of lesions (P < 0.05, P = 0.0045) and modified Thongprasom scores (P = 0.0052). The two treatments differed only in terms of the surface area of the lesions and Thongprasom scores, not in VAS scores for discomfort or the length of patients' striae. Topical tocopherol proved effective in the treatment of ROLP. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as tragacanth have been introduced in Iranian traditional medicine (ITM as depigmenting agents. Moreover, modern studies have shown their antioxidant and inhibitory mushroom tyrosinase effect.In this study, a topical gel containing Allium cepa L. and Cucumis melo L. seeds extract was prepared with tragacanth and quality control evaluations have been accomplished. Method: After performing quality control of plants seeds and tragacanth according to pharmacopoeia, the ethanol extract of A. cepa and hydroalcoholic extract of C. melo seeds were prepared. An appropriate gel formulation was selected on the base of suitable viscosity. The gel product was formulated using 5% of each plant extracts in tragacanth gel base. In addition, the herbal gel was evaluated using pharmaceutical behavior such as physical appearance, pH, viscosity, spreadability as well as phenolics content. Results: The herbal gel product showed acceptable pharmaceutical behavior as well as considerable phenolic content (1.43±0.01 mg/g. Conclusion: The prepared topical gel product could be a good natural formulation candidate for clinical studies in the field of hyperpigmentation. Moreover, phenolic content of the product could be considered as an indicator for its quality control.

    To determine whether topical acyclovir in polyethylene glycol could reduce the severity of herpes simplex labialis if applied immediately after onset of a recurrence, 10% acyclovir in polyethylene glycol ointment or polyethylene glycol alone was prospectively dispensed to 352 patients in a double-blind, randomized trial. Sixty-nine subjects initiated treatment in the prodrome (57%) or erythema (43%) stage and were followed by clinical and virological criteria. The healing time (6.0 days), maximum lesion area (42 mm2), vesicle or ulcer formation (91%), and maximum lesion virus titer (4.8 log10 PFU) in the drug recipients were not reduced in comparison with those who received the vehicle (5.2 days, 30 mm2, 75%, and 4.5 log10 PFU, respectively). Topical acyclovir in polyethylene glycol was ineffective for the treatment of herpes labialis despite an optimum therapeutic opportunity. PMID:6732224

    Topical infections, involving a number of diseases such as impetigo, eczema, pustular acne, psoriasis and infected seborrheic dermatitis are one among the many challenges to health which stand out for their profound impact on human species. The treatment of topical infections has always been a difficult proposition because of the lack of efficacy of existing anti-infectives, longer period of treatment and yet incomplete recovery. The increasing emergence of antibiotic resistant bacterial strains like Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa undermine the need of development of new delivery systems to enhance the therapeutic efficacy of existing topical anti-infectives. The application of nanotechnology to medicine, or nanomedicine, is rapidly becoming a major driving force behind ongoing changes in the anti-infective field because of its interaction at the sub-atomic level with the skin tissue. The latter, in the current scenario, points towards vesicular carriers like liposomes, lipidic nanoparticles and silver nanoparticles etc. as the most promising drug delivery solutions for topical infection disorders. These have exhibited immense significance owing to their uniqueness to facilitate the interactions at interfaces with the barrier membranes. The present review summarizes the emerging efforts in combating topical infections particularly using nanomedicine based delivery systems as new tools to tackle the current challenges in treating infectious diseases. Besides, compiling various research reports, this article also includes formulation considerations, mechanisms of penetration and patents reported. Despite the new emerging technologies and delivery systems, efforts are still needed in the right direction to combat this global challenge.

    Topical minoxidil is the only drug approved by the US FDA for the treatment of female pattern hair loss. Unfortunately, following 16 weeks of daily application, less than 40% of patients regrow hair. Several studies have demonstrated that sulfotransferase enzyme activity in plucked hair follicles predicts topical minoxidil response in female pattern hair loss patients. However, due to patients’ discomfort with the procedure, and the time required to perform the enzymatic assay it would be ideal to develop a rapid, non-invasive test for sulfotransferase enzyme activity. Minoxidil is a pro-drug converted to its active form, minoxidil sulfate, by sulfotransferase enzymes in the outer root sheath of hair. Minoxidil sulfate is the active form required for both the promotion of hair regrowth and the vasodilatory effects of minoxidil. We thus hypothesized that laser Doppler velocimetry measurement of scalp blood perfusion subsequent to the application of topical minoxidil would correlate with sulfotransferase enzyme activity in plucked hair follicles. In this study, plucked hair follicles from female pattern hair loss patients were analyzed for sulfotransferase enzyme activity. Additionally, laser Doppler velocimetry was used to measure the change in scalp perfusion at 15, 30, 45, and 60 minutes, after the application of minoxidil. In agreement with our hypothesis, we discovered a correlation (r=1.0) between the change in scalp perfusion within 60 minutes after topical minoxidil application and sulfotransferase enzyme activity in plucked hairs. To our knowledge, this is the first study demonstrating the feasibility of using laser Doppler imaging as a rapid, non-invasive diagnostic test to predict topical minoxidil response in the treatment of female pattern hair loss.

    Vitiligo is the most common acquired hypopigmentary disease in the community. Piperine as an herbal extract derived from black pepper has strong impact on the melanocyte proliferation and adverse side effects less than synthetic drugs such as corticosteroids. For the first time, this study was aimed to evaluate the effect of topical piperine combined with narrowband ultraviolet B (NB-UVB) on vitiligo treatment. In this double-blind clinical trial, 63 patients with facial vitiligo were randomly divided into 2 groups: treated with piperine (case) and placebo (control). Also, both groups received NB-UVB phototherapy every other day for 3 months. In the case group, 10 patients have burning sensation on their skin areas (p value = .002). Also, redness of the treated areas was observed in 6 patients (p value = .028). Both side effects were temporary. Regarding repigmentation at time intervals of 1, 2, and 3 months after treatment, its level in the case group was significantly higher than the control group (p value topical piperine has more influence on facial vitiligo than that of NB-UVB alone. It could be concluded that the simultaneous use of NB-UVB and topical piperine has a remarkable effect on treatment of vitiligo. Copyright © 2018 John Wiley & Sons, Ltd.

    Alopecia areata (AA) is one of the most common causes of localized hair loss. There is no universally proven therapy that induces and sustains remission of hair growth in AA. To compare the efficacy and safety of topical latanoprost, minoxidil and betamethasone valerate on hair growth in patients with AA. Hundred patients with AA classified into five groups of 20 treated with: Group I, latanoprost 0.1% lotion; Group II, minoxidil 5% lotion; Group III, betamethasone valerate 0.1% solution; Group IV, combination of latanoprost lotion and betamethasone valerate solution and Group V, a vehicle lotion control group. There was a statistically significant improvement in all therapeutic groups when compared with control group and reduction of severity of alopecia tool score of scalp and beard before and after treatment for all therapeutic groups. Latanoprost, minoxidil and betamethasone valerate are effective and safe in the treatment of patchy AA. The use of latanoprost added to the therapeutic efficacy of topical betamethasone valerate in the treatment of AA and could be an effective adjunctive topical therapy for AA.

    Tenoxicam (TNX) is a non-steroidal anti-inflammatory drug (NSAID) used for the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, backache and pain. However, prolonged oral use of this drug is associated with gastrointestinal adverse events like peptic ulceration, thus necessitating its development as topical formulation that could obviate the adverse effects and improve patient compliance. The present study was aimed at development of microemulsion-based formulations of TNX for topical delivery at the affected site. The pseudoternary phase diagrams were developed and microemulsion formulations were prepared using Captex 300/oleic acid as oil, Tween 80 as surfactant and n-butanol/ethanol as co-surfactant. Optimized microemulsions were characterized for drug content, droplet size, viscosity, pH and zeta potential. The ex vivo permeation studies through Laca mice skin were performed using Franz diffusion cell assembly, and the permeation profile of the microemulsion formulation was compared with aqueous suspension of drug and drug incorporated in conventional cream. Microemulsion formulations of TNX showed significantly higher (p Microemulsion formulations were found to be superior in controlling inflammation as compared to conventional topical dosage forms and showed efficacy equivalent to oral formulation. Results suggest that the developed microemulsion formulations may be used for effective topical delivery of TNX to treat various inflammatory conditions.

    Pain associated with integumentary wounds is highly prevalent, yet it remains an area of significant unmet need within health care. Currently, systemically administered opioids are the mainstay of treatment. However, recent publications are casting opioids in a negative light given their high side effect profile, inhibition of wound healing, and association with accidental overdose, incidents that are frequently fatal. Thus, novel analgesic strategies for wound-related pain need to be investigated. The ideal methods of pain relief for wound patients are modalities that are topical, lack systemic side effects, noninvasive, self-administered, and display rapid onset of analgesia. Extracts derived from the cannabis plant have been applied to wounds for thousands of years. The discovery of the human endocannabinoid system and its dominant presence throughout the integumentary system provides a valid and logical scientific platform to consider the use of topical cannabinoids for wounds. We are reporting a prospective case series of three patients with pyoderma gangrenosum that were treated with topical medical cannabis compounded in nongenetically modified organic sunflower oil. Clinically significant analgesia that was associated with reduced opioid utilization was noted in all three cases. Topical medical cannabis has the potential to improve pain management in patients suffering from wounds of all classes. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    2016-04-01

    Full Text Available Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hypervascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly.

  12. Evolving guidelines in the use of topical nonsteroidal anti-inflammatory drugs in the treatment of osteoarthritis.

    2014-01-21

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are a standard treatment for osteoarthritis (OA), but the use of oral NSAIDs has been linked to an elevated risk for cardiovascular and gastrointestinal adverse events and renal toxicity. Topical NSAIDs are thought to afford efficacy that is comparable to oral formulations while reducing widespread systemic drug exposure, which may provide a benefit in terms of safety and tolerability. As a result, European treatment guidelines have, for many years, recommended the use of topical NSAIDs as a safe and effective treatment option for OA. Following the recent approval of several topical NSAID formulations by the US Food and Drug Administration, US treatment guidelines are increasingly recommending the use of topical NSAIDs as an alternative therapy and, in some cases, as a first-line option for OA. This commentary summarizes OA treatment guidelines that are currently available and discusses their potential evolution with regard to the increased inclusion of topical NSAIDs.

    Full Text Available Background: Serum estradiol level is a controversial prognostic factor in the outcome of labial adhesion. The aim of this study was to evaluate serum estradiol levels and topical estrogen response in patients with labial adhesion.Methods: A prospective interventional study was conducted among girls with labial adhesion that referred to Pediatrics clinic in Taleghani University Hospital, Gorgan city, Iran in 2011. One hundred patients entered the study. The diagnosis was conducted by clinical examination of vestibule area. Inclusion criteria were, three months to eight years old prepuberty girls, no ambiguous genitalia, lack of vulvovaginitis symptoms, labial adhesion more than twenty five percent, no history of previous topical estrogen treatment since two weeks ago and previous incomplete treatment. The patients who did not use proper amount and duration of drug and also with adverse drug reactions during treatment period were excluded from the study. Results: The maximum frequency of labial adhesion was in the group of less than one year old. The minimum frequency of labial adhesion was in the 7-8 years old group. Eighty six patients had complete or partial remission. No evidence of an improvement was observed in fourteen children. Severity of adhesions did not worsen in our patients. Serum estradiol levels were lower in patients who had a positive response to treatment. There were significant differences in serum estradiol levels between full or relative improvement with no improvement groups (P=0.044.Conclusion: Findings of this study showed that the labial adhesion patients with low serum estradiol level had better treatment response after using topical estrogen.

    To examine the effect of topical corticosteroid treatment on acute sunburn. Randomized, double-blind clinical trial. University dermatology department. Twenty healthy volunteers with Fitzpatrick skin types I (highly sensitive, always burns easily, tans minimally) through III (sun-sensitive skin, sometimes burns, slowly tans to light brown). Seven 34-cm(2) areas were marked on the upper aspect of the back of each participant. An untreated area was tested to determine UV sensitivity. Two areas were treated with excess amounts (2 mg/cm(2)) of either a moderate-potency corticosteroid or a high-potency corticosteroid 30 minutes before UV-B exposure as controls. Six or 23 hours after exposure to radiation, the remaining areas were treated with the 2 corticosteroid preparations. The sunburn improvement factor (SIF) was determined by the following equation: SIF = MED (minimal erythema dose) on treated skin/MED on nontreated skin. An SIF greater than 1 indicated an effect of topical corticosteroids in sunburn relief. The SIFs in the areas treated with either topical corticosteroid 30 minutes before UV-B exposure or high-potency corticosteroid 6 hours after UV-B exposure were significantly different from SIFs in areas that received no treatment (SIF 1.1-1.7; P sunburn reaction when applied 6 or 23 hours after UV exposure.

    The use of pain relief during castration and dehorning of calves on commercial beef operations can be limited by constraints associated with the delivery of analgesic agents. As topical anaesthetic (TA) and buccal meloxicam (MEL) are now available in Australia, offering practical analgesic treatments for concurrent castration and dehorning of beef calves, a study was conducted to determine their efficacy in providing pain relief when applied separately or in combination. Weaner calves were randomly allocated to; (1) no castration and dehorning/positive control (CONP); (2) castration and dehorning/negative control (CONN); (3) castration and dehorning with buccal meloxicam (BM); (4) castration and dehorning with topical anaesthetic (TA); and (5) castration and dehorning with buccal meloxicam and topical anaesthetic (BMTA). Weight gain, paddock utilisation, lying activity and individual behaviours following treatment were measured. CONP and BMTA calves had significantly greater weight gain than CONN calves ( p castrated calves spent more time walking ( p = 0.024) and less time eating ( p castration and amputation dehorning.

    The use of Monte Carlo particle transport simulations in radiotherapy was pioneered in the early nineteen-seventies, but it was not until the eighties that they gained recognition as an essential research tool for radiation dosimetry, health physics and later on for radiation therapy treatment planning. Since the mid-nineties, there has been a boom in the number of workers using MC techniques in radiotherapy, and the quantity of papers published on the subject. Research and applications of MC techniques in radiotherapy span a very wide range from fundamental studies of cross sections and development of particle transport algorithms, to clinical evaluation of treatment plans for a variety of radiotherapy modalities. The International Workshop on Current Topics in Monte Carlo Treatment Planning took place at Montreal General Hospital, which is part of McGill University, halfway up Mount Royal on Montreal Island. It was held from 3-5 May, 2004, right after the freezing winter has lost its grip on Canada. About 120 workers attended the Workshop, representing 18 countries. Most of the pioneers in the field were present but also a large group of young scientists. In a very full programme, 41 long papers were presented (of which 12 were invited) and 20 posters were on display during the whole meeting. The topics covered included the latest developments in MC algorithms, statistical issues, source modelling and MC treatment planning for photon, electron and proton treatments. The final day was entirely devoted to clinical implementation issues. Monte Carlo radiotherapy treatment planning has only now made a slow entrée in the clinical environment, taking considerably longer than envisaged ten years ago. Of the twenty-five papers in this dedicated special issue, about a quarter deal with this topic, with probably many more studies to follow in the near future. If anything, we hope the Workshop served as an accelerator for more clinical evaluation of MC applications. The

    Full Text Available Topical medicinal patches have been popular for the treatment of minor injuries like sprains and avulsions. Other inflammatory conditions like chronic musculo-tendinous pain and or fasciitis are also taken care of by local ointments or rubs. In the oriental communities, medicinal herbs frequently form the major components of the patches.In spite of the lack of scientific evidence of efficacy, the popularity of such traditional application persists for centuries.In this era of evidence-based clinical treatment, there is an urgent need to look into this traditional practice. The purpose should include a scientific verification of the efficacy of the practice, and once proven, further explorations would be indicated to bring the practice to a higher level.A system of comprehensive exploration was proposed and practiced in the past years to fulfill the aspiration. The research consisted of four areas:(1Identification of the suitable medicinal herbs for the topical study;(2Study of the biological activities of the selected herbs, concentrating on the areas of anti-inflammation, anti-oxidation, angiogenesis and cellular proliferation;(3Study on the transcutaneous transport of the chemicals of the selected herbs to deeper tissues; and(4Pilot clinical studies on common superficial inflammatory musculo-skeletal conditions to give objective clinical evidences to the topical applications.Five herbs were identified as suitable candidates of study. They were put into relevant laboratory platforms and were proven to be anti-oxidant, anti-inflammatory and pro-angiogenic. Three of the herbs were prepared as topical patches with an enhancer and used to treat three common ailments in pilot clinical trials, viz., plantar fasciitis, undisplaced metatarsal fracture and tendonitis of the wrist (de-Quervain’s disease and the elbow (Tennis elbow. The clinical results of the pilot studies were very positive.It is therefore concluded that further explorations are

  19. Evolution of topical NSAIDs in the guidelines for treatment of osteoarthritis in elderly patients.

    2012-07-01

    Increasing age is the primary predictor of osteoarthritis, the most prevalent painful condition in the US. Because there are no disease-modifying therapies for osteoarthritis, relief of symptoms and maintenance of quality of life through improving joint function become the focus of management. Although highly effective for pain relief, oral nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with systemic adverse reactions that are sometimes treatment limiting, especially for older patients. Thus, osteoarthritis management in elderly populations is shifting away from traditional NSAIDs to therapies that provide comparable pain relief with improved safety. Since the approval by the US Food and Drug Administration of the use of topical NSAIDs to manage osteoarthritis pain, current treatment guidelines put forth by several professional societies have begun to recommend topical NSAIDs as an alternative therapy and, most recently, as first-line therapy for osteoarthritis management in the elderly. This review provides an overview of the various treatment guidelines that are available to assist prescribers in making safe and effective decisions in the treatment of osteoarthritis in this high-risk patient population.

  20. Topical tacrolimus for the treatment of severe allergic keratoconjunctivitis in children

    Directory of Open Access Journals (Sweden)

    Vera Lucia Liendo

    Full Text Available ABSTRACT Purpose: Administration of eye drops containing antihistamines or sodium cromoglycate and its derivatives for the treatment of allergic keratoconjunctivitis is often insufficient and usually requires the addition of corticosteroids. However, the risk of complications, such as glaucoma and cataract, limits the use of corticosteroids to short courses, resulting in inadequate long-term treatment response. Immunosuppressive drugs have been considered as a valid alternative to steroids for atopic keratoconjunctivitis and vernal keratoconjunctivitis. This study aimed to evaluate the use of topical tacrolimus (TCL in improving the clinical signs of severe allergic keratoconjuctivitis in children. Methods: Patients with severe allergic keratoconjunctivitis associated with corneal epitheliopathy, gelatinous limbal infiltrates, and/or papillary reaction, along with a history of recurrences and resistance to conventional topical anti-allergy agents, were included in this open clinical trial. Patients were treated with 0.03% TCL ointment for ocular use. A severity score ranging from 0 to 9, with 9 being the highest and 0 being the lowest, was assigned based on signs observed on biomicroscopy prior to and following TCL treatment. Results: Analyses included 66 eyes of 33 patients. After a mean follow-up period of 13 months (range, 12-29 months, TCL treatment significantly decreased the mean symptom score severity for the right (from 5.56 ± 1.18 to 2.76 ± 1.5; p<0.001 and left (from 5.94 ± 1.16 to 2.86 ± 1.64; p<0.001. Conclusion: Topical TCL was effective and significantly improved the clinical signs of allergic keratoconjuctivitis in children. Thus, it is a potential new option for severe and challenging cases of ocular allergy.

    Leishmaniasis is a spectrum of disease condition with considerable health impacts, caused by different species of Leishmania . This disease is currently endemic in 98 countries and territories in the world. There are many treatment modalities for cutaneous leishmaniasis. The use of topical terbinafine in the treatment of cutaneous leishmaniasis has recently been considered. Eighty-eight participants more than two years old with proven acute CL by a positive direct smear were randomly allocated to one of the two study arms: first group received meglumine antimoniate (Glucantime) 20 mg/kg/day intramuscular injection (IM) plus a placebo ointment (Mahan Vaseline) for 20 days. The second group received meglumine antimoniate (Glucantime) 20 mg/kg/day IM plus topical terbinafine, for 20 days and were monitored closely by dermatologist during the course of the study. Crude regression analysis showed that there was no significant difference between placebo and intervention group regarding partial or complete treatment (partial treatment: HR crude  = 1.1, CI 95 % = 0.7-1.7; complete treatment: HR crude  = 1.1, CI 95 % = 0.8-1.7). Although, there was no statistically significant different between the two treatment groups, but clinically it seems that the treatment rate in those who receive glucantime plus terbinafine was more effective than the other group. However this rate depended on the type of lesions. As data indicated ulcerated nodules, papules and plaque in experimental group have been completely improved two times faster than placebo group. Ulcerated nodules, nodules and plaque were partially improved faster in those used tebinafine than placebo ointment.

    Full Text Available Diabetes mellitus (DM is a metabolic disease which is becoming the first number of health problem in Indonesia, based on the results of the Basic Health Research of Ministry of Health in 2013. One of the diabetes complications affected by high levels of blood glucose is diabetic ulcers wich 85% the number of cases was overed by amputation as the result of improper handling. Herbal treatments could be an alternative treatment of diabetic ulcers, one of them is binahong plant. The results of previous studies have shown the ability of ethanolic extract of binahong leaf in accelerating wound healing in diabetic rats. This study would be a continued study to test five kinds of binahong leaf fractions (FDB with gradual solvent polarity in accelerating wound healing in diabetic ulcer. Wound healing parameters observed were percentage of wound healing from the wound diameter contraction. The test begins with ethanolic extract of binahong leaf fractionation to produce fractions of hexane (FHDB, chloroform (FKDB, ethyl acetate (FEADB, and ethanol (FEDB. Water fraction (FADB was obtained from ethanolic leaf extract residues of binahong leaf extraction. Each fraction activity was tested topically twice daily on dorsal of test animals that created wounds using a punch biopsy 5 mm diameters. Grouping of test animals were divided into 13 groups with normal control group (non diabetes, negative control (diabetes + topical application of biocream®, positive control (diabetes + topical application of madecassol, and 10 diabetes groups with topical application of 5 kinds of binahong leaf fractions with each fractions consist of a concentrations of 5% and 10% with biocream® as a vehicle. Diabetic parameters measured include blood glucose levels (KGD and weight lost percentage (PB% in day 1 and 10 during a 10-day treatment. The results showed the influence of KGD in the condition of diabetes on wound healing rats diabetic ulcers which topically treated with

    Recent research suggests that statins might be useful in the process of wound healing, playing a positive immune-modulatory role, improving microvascular function and reducing oxidative stress. The aim of this pilot study was to evaluate the efficacy of topic application of Simvastatin-based cream in the treatment of chronic vascular cutaneous ulcers, comparing this type of treatment to a collagen-based dressing, proven to be effective for ulcer treatment. A total of 20 ulcers were studied in 2 Groups of randomly-chosen patients for a period of one month. In the first Group a 0.5% Simvastatin-based cream was topically administered, while the second Group (control) was treated with an absorbable type I bovine collagen-based medication. Each week, wound healing progress was observed in both Groups, and the ulcers photographed. Wound healing rate was calculated by considering the absolute change in area and by the formula "healing ratio (%) = [(Area 0 - Area t4 )/Area 0 ] × 100," both sets of data being related to the days comprised in the study in order to calculate healing rate per day. Statistical analysis was performed by Student t test. Study endpoint equaling the time-course changes of ulcer areas. At the end of the study, when considering absolute change in area, the experimental Group appeared to heal better and faster than the control Group although differences between the Groups were not statistically significant. Conversely, rates of wound healing in the experimental and control Groups were 46.88% and 64% respectively, revealing statistically significant differences. ( P topic application of a simvastatin-based cream proved to be well- tolerated but not effective in the management of vascular leg ulcers in a 4 week-period.

    To evaluate efficacy of oral dextrose, in addition to topical anesthesia in providing pain relief during laser ablation therapy of retinopathy of prematurity (ROP). In this randomized controlled trial, neonates with type 1 ROP undergoing laser ablation of peripheral retina were randomized to receive or not to receive 2 ml of 25 % dextrose orally just before the laser therapy. In both the groups, topical anesthesia was provided by instilling paracaine eye drops twice at 10 min interval just before the laser treatment. Main outcome was Premature Infant Pain Profile (PIPP) recorded before and 30 s after starting the laser treatment. Birth weight, gestation, stage and extent of ROP and other baseline variables were comparable among neonates randomized to dextrose (n = 12) or control (n = 12) groups. Both groups required comparable number of laser spots. PIPP scores was comparable in neonates randomized to dextrose or control groups and indicated significant amount of pain felt during laser ablation despite local anesthesia with or without oral dextrose. Single dose of oral dextrose did not significantly reduce pain during laser treatment in premature neonates. Further studies with multiple doses of dextrose and its combination with other non-pharmacological (e.g., behavioral, physical) interventions may be needed.

    Actinic keratosis (AK) is a common skin disease seen in daily practice. It is associated with a risk of progression to invasive squamous cell carcinoma and can be regarded as a marker of increased risk for non-melanoma skin cancer. The use of a field-directed treatment approach reflects the need to initiate early treatment over an affected area to prevent tumour development and local recurrence. Candidate field-directed treatments require a mechanism of action compatible with an effect on field cancerisation, immediate and long-term efficacy against visible lesions and efficacy against subclinical AK. Applicability to large treatment areas, tolerability compatible with long-term use, utility in organ transplant patients and, ideally, evidence of extended long-term activity may also be desirable. We review the evidence of a role for topical diclofenac sodium 3% administered in a 2.5% hyaluronic acid gel (diclofenac/HA) as field-directed treatment. Diclofenac/HA directly targets AK pathophysiology through multiple mechanisms, including induction of apoptosis, inhibition of angiogenesis and reduced inflammation. Clearance of visible field cancerisation is safely and rapidly achieved with a 90-day treatment course in patients with affected areas of up to 50 cm(2) and is associated with a ≥75% reduction in target lesion number score in 85% and 91% of patients, respectively, at 30 days and 1 year post-treatment. Following treatment of AK in high-risk transplant patients, 45% remained free of lesions in the treatment area at 2 years post-treatment. We conclude that diclofenac/HA fulfils most criteria necessary to be considered an appropriate candidate for a field-directed treatment in AK.

    Sucralfate is a cytoprotective agent which adheres to mucoproteins and forms a protective barrier at wound sites. In oral form it is a common ulcer medication, and as a topical preparation it has been used to treat a wide variety of wounds. The present study was designed to evaluate the effectiveness and safety of topical sucralfate in wound healing after anal fistulotomy. Double-blind, randomized controlled study comparing topical application of sucralfate or placebo. Private outpatient clinic specializing in anorectal disease in Nagpur, India. Patients with a wound length of at least 5 cm after low anal fistulotomy were eligible for the study. Patients were randomly assigned to receive ointment containing 7% sucralfate or a placebo ointment consisting of petroleum jelly. Patients were instructed to apply approximately 3 g of ointment to the wound twice daily after a sitz bath for 6 weeks or until the wound had healed. The wounds were examined by a blinded independent observer at 2, 4, and 6 weeks after the operation. The primary end point was the proportion of patients with wounds that had completely healed. Secondary end points included amount of mucosal covering (scored by the observer), adverse events, and postoperative pain (self-rated on a visual analog scale). Of 80 participants (29 women, 51 men; median age, 23 (range, 17-49) years), 76 participants completed the trial (sucralfate, 39; placebo, 37). At 6-week follow-up, complete wound healing was achieved in 37 patients (95%) in the sucralfate group and 27 patients (73%) in the placebo group (P = .009). Mucosal coverage of the wound was significantly greater with sucralfate than with placebo at each measurement point (P = .01). No adverse events were observed. Postoperative pain scores were significantly lower for sucralfate than for placebo at 2 and 4 weeks after the start of treatment. Wound tissue specimens were not available for morphological and ultrastructural analysis. The results of this study add

    Many over the counter topical products claim to reverse the signs of cutaneous photo-damage. To date, the two most studied ingredients for improving the texture, tone, and pigmentation of the skin are topical retinoids and hydroquinone. This split face study compares a mass market skincare regimen with a prescription skin care regimen for improvement in photo damaged skin. Twenty-seven subjects with moderate photo damaged facial skin were enrolled. Each subject was consented and assigned with the mass market anti-aging system (Treatment A) to one side of the face and the prescription anti-aging system (Treatment B or Treatment C) to the other side of the face. Treatment B contained 13 subjects whom did not use 0.025% Retinol cream. Treatment C contained 14 subjects who used a 0.025% Retinol Cream. Subjects had 4 visits over 12 weeks for digital photography and surveys. Photographs were evaluated by blinded physicians. Physician objective analysis showed all three systems to have a statistically significant clinical improvement in photoaged skin seen in as little as 4 weeks of use. Participant's surveys rated the mass market system higher than both of the professional systems for visible skin changes, ease of use, and likelihood to recommend to a friend. Twelve of twenty-seven subjects preferred the mass market system for overall improvement while twelve thought each system gave the same improvement. This study demonstrates that a mass marketed skin care system can give similar clinical improvements in photo-aged skin as a professionally dispensed prescription system and the majority of participants preferred the mass-marketed system.

    Plane wart is a common dermatological disease that is caused by human papilloma virus; although the rate of spontaneous recovery is high, it usually takes a long time to occur. Many modalities of treatments have been used but none of them proved to be uniformly effective. Potassium hydroxide (KOH) solution is a well-known keratolytic agent with many dermatological uses. To evaluate the efficacy and tolerability of topical KOH solution in the treatment of plane warts. A total of 250 patients with plane warts, consulting the department of Dermatology and Venereology of Basra Teaching Hospital between March 2008 and October 2009, were enrolled in this opened therapeutic trial study. Patients were divided into two age and sex cross-matched equal groups; patients in group (A) were treated with topical 5% KOH solution once at night, while patients in group (B) were treated with topical 10% KOH solution once nightly. Only 107 patients from group (A) and 95 patients from group (B) completed the study, while the remainders were defaulted for unknown reasons. The patients were evaluated at second and fourth week to assess the cure rates and side effects, those patients who showed complete cure were followed up for 3 months to detect any recurrence. At the end of second week, 9.3% of group (A) patients showed complete disappearance of their warts, vs 66.3% of group (B) patients. At the end of fourth week, 80.3% of group (A) patients showed complete response in comparison with 82.1% of group (B) patients. The side effects for the treating solution in both concentrations include itching, burning sensation, erythema, and temporary dyspigmentations, that were reported in 77.6% of group (A) patients in comparison with 90.5% of group (B) patients. Recurrence rate was reported in 5.8% of group (A) patients vs 5.1% of group (B) patients during the three months period of follow-up.

    Full Text Available Background & Objectives: Considering the prevalence of Alopecia areata, , failure of treatment, and the unknown pathogenesis of this illness, a comparative study was performed by using topical Minoxidil 2% and topical rosemary solution alone and in combination to treatment this disease. Materials & Methods: This study is a clinical trial performed on 200 patients with Alopecia areata referring to Hamzeh clinic of Fasa during the years 2012 and 2013. They were divided into four groups by random permutation, each group contained 50 patients. Group one received the combination of topical Minoxidil 2% and topical rosemary, group two received only topical Minoxidil 2% solution, group three received only topical rosemary solution and the fourth group, the case-control group, did not receive any medication and were just advised to rub the site of the disease for the same period of time. The patients were under observation for one year. Results: The Results of this investigation showed that the best remissions after treatments were as follow (respectively: combination of topical Minoxidil 2% and topical rosemary (27 patient=54 %, Minoxidil 2% solution (23 patients =46%, rosemary solution (21 patients =42%, and case- control group (9 patients =18%. These results showed that despite better response to the combination of rosemary and Minoxidil solutions in comparison to the two other treated groups, the changes were minimal and statistically insignificant (P-value =0.0411. Conclusion: Using the combination of both rosemary and Minoxidil is more effective than the individual one on treatment of Alopecia areata.

    The purpose of this study was to compare the apoptotic responses to systemic, topical, and intrapolyp injection of glucocorticoid with no treatment in nasal polyps. Prospective, randomized controlled study. Tertiary training hospital. The study was performed on 48 patients with nasal polyposis in the Department of Otorhinolaryngology between 2008 and 2009. Patients were assigned to 1 of 4 groups of 12 patients. Group A was treated with oral methylprednisolone 1 mg/kg/d, and the dose was tapered gradually. Group B received 0.3 mL triamcinolone acetonide (40 mg/mL), which was injected into polyp tissue. Group C was treated with topical 55 µg triamcinolone acetonide 2 times daily for 1 month. Group D received no medication. Samples were collected endoscopically after the seventh day for groups A and B, the first month for group C, and the first visit for group D. Apoptotic indexes were determined using the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method. Statistically significant differences in apoptotic index were found between each steroid-medicated group and the control group (P (D-A) = .0001; P (D-B) = .003; P (D-C) = .026) and between groups A and C (P (A-C) = .012). Group B did not differ significantly from either group A or C (P (A-B) = .11; P (B-C) = .75). The apoptotic index in nasal polyps treated with systemic, topical, and intrapolyp injection forms of glucocorticoids was higher than that in the control group. Systemic steroid treatment induced the most apoptosis.

    Venous leg ulcers are an important medical issue due to their high incidence in the elderly and the lack of a standard curative approach. Apart from surgical therapy, different medical treatments to effect ulcer wound repair and regeneration are currently being investigated. Sucralfate is a cytoprotective agent employed to prevent or treat several gastrointestinal diseases such as gastroesophageal reflux, gastritis, peptic ulcer, stress ulcer and dyspepsia. In this study we evaluated the efficacy, safety and tolerability of topical sucralfate (SUC-LIS 95) on the healing of chronic venous leg ulcers in 50 patients by a double-blind, placebo-controlled, randomized study. Our results indicated that the daily application of SUC-LIS 95 to non-infected post-phlebitis/vascular ulcers, for a median period of 42.0 days, led to complete healing in 95.6% of patients, against only 10.9% of cases with a matched placebo. A significant improvement was obtained in the SUC-LIS 95-treated patient group with regard to local tissue inflammation as well as pain and burning, and consequently, in ulcer size and the evolution of granulation tissue. Our findings were corroborated for selected patients by the morphological analysis of biopsies obtained before and after treatment. Using ultrastructural analysis we demonstrated that the topical use of SUC-LIS 95 was able to affect neoangiogenesis, increase wound contraction, promote re-epithelialization of the wound area and diminish the inflammatory reaction. Overall, our results indicated that patients with chronic venous ulcers show improvement after the use of topical sucralfate.

    Full Text Available The use of pain relief during castration and dehorning of calves on commercial beef operations can be limited by constraints associated with the delivery of analgesic agents. As topical anaesthetic (TA and buccal meloxicam (MEL are now available in Australia, offering practical analgesic treatments for concurrent castration and dehorning of beef calves, a study was conducted to determine their efficacy in providing pain relief when applied separately or in combination. Weaner calves were randomly allocated to; (1 no castration and dehorning/positive control (CONP; (2 castration and dehorning/negative control (CONN; (3 castration and dehorning with buccal meloxicam (BM; (4 castration and dehorning with topical anaesthetic (TA; and (5 castration and dehorning with buccal meloxicam and topical anaesthetic (BMTA. Weight gain, paddock utilisation, lying activity and individual behaviours following treatment were measured. CONP and BMTA calves had significantly greater weight gain than CONN calves (p < 0.001. CONN calves spent less time lying compared to BMTA calves on all days (p < 0.001. All dehorned and castrated calves spent more time walking (p = 0.024 and less time eating (p < 0.001 compared to CONP calves. There was a trend for CONP calves to spend the most time standing and CONN calves to spend the least time standing (p = 0.059. There were also trends for the frequency of head turns to be lowest in CONP and BMTA calves (p = 0.098 and tail flicks to be highest in CONN and BM calves (p = 0.061. The findings of this study suggest that TA and MEL can potentially improve welfare and production of calves following surgical castration and amputation dehorning.

  14. JAK3 as an Emerging Target for Topical Treatment of Inflammatory Skin Diseases.

    Directory of Open Access Journals (Sweden)

    Ana Karina Alves de Medeiros

    Full Text Available The recent interest and elucidation of the JAK/STAT signaling pathway created new targets for the treatment of inflammatory skin diseases (ISDs. JAK inhibitors in oral and topical formulations have shown beneficial results in psoriasis and alopecia areata. Patients suffering from other ISDs might also benefit from JAK inhibition. Given the development of specific JAK inhibitors, the expression patterns of JAKs in different ISDs needs to be clarified. We aimed to analyze the expression of JAK/STAT family members in a set of prevalent ISDs: psoriasis, lichen planus (LP, cutaneous lupus erythematosus (CLE, atopic dermatitis (AD, pyoderma gangrenosum (PG and alopecia areata (AA versus healthy controls for (pJAK1, (pJAK2, (pJAK3, (pTYK2, pSTAT1, pSTAT2 and pSTAT3. The epidermis carried in all ISDs, except for CLE, a strong JAK3 signature. The dermal infiltrate showed a more diverse expression pattern. JAK1, JAK2 and JAK3 were significantly overexpressed in PG and AD suggesting the need for pan-JAK inhibitors. In contrast, psoriasis and LP showed only JAK1 and JAK3 upregulation, while AA and CLE were characterized by a single dermal JAK signal (pJAK3 and pJAK1, respectively. This indicates that the latter diseases may benefit from more targeted JAK inhibitors. Our in vitro keratinocyte psoriasis model displayed reversal of the psoriatic JAK profile following tofacitinib treatment. This direct interaction with keratinocytes may decrease the need for deep skin penetration of topical JAK inhibitors in order to exert its effects on dermal immune cells. In conclusion, these results point to the important contribution of the JAK/STAT pathway in several ISDs. Considering the epidermal JAK3 expression levels, great interest should go to the investigation of topical JAK3 inhibitors as therapeutic option of ISDs.

    Several topical treatments are used in the management of Chronic Rhinosinusitis (CRS), some of which the safety and efficacy has yet to be determined. The purpose of this study was to investigate the effect of commonly used topical treatments on the sinonasal epithelial barrier. Normal saline (0.9% Sodium Chloride), hypertonic saline (3% Sodium Chloride), FESS Sinu-Cleanse Hypertonic, FLO Sinus Care and Budesonide 1 mg/ 2 ml were applied to the apical side of air-liquid interface (ALI) cultures of primary human nasal epithelial cells (HNECs) from CRS patients (n=3) and non-CRS controls (n=3) for 24 hours. Epithelial barrier structure and function was assessed using trans-epithelial electrical resistance (TEER), measuring the passage of Fluorescein Isothiocyanate labelled Dextrans (FITC-Dextrans) and assessing the expression of the tight junction protein Zona Occludens-1 (ZO-1) using immunofluorescence. Toxicity was assessed using a Lactate Dehydrogenase (LDH) assay. Data was analysed using ANOVA, followed by Tukey HSD post hoc test. Hypertonic solution and budesonide significantly increased TEER values in CRS derived HNECs. In contrast, FESS Sinu-Cleanse Hypertonic significantly reduced TEER 5 minutes after application of the solution followed by an increase in paracellular permeability of FITC-Dextrans (30 minutes) and increased LDH levels 6 hours after application of the solution. Our findings confirm that isotonic and hypertonic saline solutions do not compromise epithelial barrier function in vitro but underscore the importance of examining safety and efficacy of over-the-counter wash solutions.

    Full Text Available Spencer M Onishi, Masumi G Asahi, Calvin Chou, Ron P Gallemore Retina Macula Institute, Torrance, CA, USA Purpose: To describe the use of topical difluprednate for treatment of patients who presented with Harada’s disease.Methods: Retrospective case series of patients managed with topical difluprednate alone at the onset of the diagnosis. The patients were followed with optical coherence tomography (OCT and fluorescein angiography.Results: In our three cases, complete resolution of the exudative detachments with improvement in visual acuity was achieved in each case. Central macular thickness was reduced by a mean of 365±222 µm. Initial loading dose was one drop every hour while awake, followed by a variable tapering regimen. Leakage on fluorescein angiography and exudative detachments on OCT both responded to treatment with difluprednate. In two of the three cases, the patients recovered vision to 20/20, and the third case recovered to 20/25. Steroid-induced glaucoma was observed and managed with one to two glaucoma drops as needed.Conclusion: Difluprednate is effective for managing ocular manifestations of Harada’s disease. Further studies of this drug for the management of noninfectious posterior uveitis are warranted. Keywords: serous retinal detachment, noninfectious posterior uveitis, steroid

    Full Text Available Background: Treatment of plaque-induced periodontal disease is largely based on the mechanical debridement of the tooth surface and meticulous maintenance of oral hygiene thereafter. Various chemical plaque control agents are used as adjuncts along with the mechanical plaque control methods for this treatment. Most of these chemical plaque control agents have varied side effects. This has led to the search of natural products which are highly effective in controlling plaque microbes while being biocompatible. Turmeric is one such well-known plant product, known for its varied medicinal value. Aim: The aim of this study is to evaluate the clinical efficacy of Curcuma longa oral formulation in treatment of infective inflammatory early periodontal diseases. Materials and Methods: This clinical study comprised twenty individuals presenting with clinical features of plaque-induced gingivitis and mild periodontitis. Three groups were randomly made in mouth of each patient selected for the study. Group I was treated with scaling and root planing (SCRP only. Group II was treated with SCRP plus C. longa oral formulation topical application for 2 weeks. Group III was treated only with topical application of C. longa extract oral formulation for 2 weeks. Gingival index, sulcus bleeding index, and plaque index were scored in each group before and after the treatment. Results: The results showed statistically significant improvement with respect to all the clinical parameters in all the three groups. However, Group II showed the maximum improvement (P < 0.001, followed by Group I (P < 0.001 and Group III (P < 0.05. The intergroup difference between the three groups for the improvements in clinical parameters was statistically nonsignificant. Conclusion: The oral formulation containing C. longa extract is effective in treating early infective-inflammatory periodontal diseases not only when used as an adjunct to SCRP but also when used alone.

    A recently performed randomised controlled trial investigated the clinical effectiveness of dermal substitutes (DS) and split skin grafts (SSG) in combination with topical negative pressure (TNP) in the surgical treatment of burn wounds. In the current study, medical and non-medical costs were investigated, to comprehensively assess the benefits of this new treatment. The primary outcome was mean total costs of the four treatment strategies: SSG with or without DS, and with or without TNP. Costs were studied from a societal perspective. Findings were evaluated in light of the clinical effects on scar elasticity. Eighty-six patients were included. Twelve months post-operatively, highest elasticity was measured in scars treated with DS and TNP (p=0.027). The initial cost price of treatment with DS and TNP was €2912 compared to treatment with SSG alone €1703 (ptreatment contributed maximal 7% to the total costs and total costs varied widely within and between groups, but were not significantly different. Therefore, in the selection of the most optimal type of surgical intervention, cost considerations should not play an important role. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    The development of cross-sectoral quality assurance programs usually requires extensive topic identification. Illustrated by the complex processes of care for stroke and transient ischemic attacks (TIAs), a method for comprehensive topic identification is presented. The first step involves a thorough literature search in terms of systematic reviews, health technology assessments, guidelines, studies into healthcare delivery and the use of specific instruments. Routine data as well as epidemiologic studies are used to analyze the reality of service provision. In addition, experts are consulted to gain expertise concerning deficits of care, approaches to quality assurance and experience with existing quality assurance programs. Furthermore individual patient experiences are collected to add the patients' perceptions of care. Because of the limitation on the regulatory scope of Book V of the German Social Code, which, in this case, was necessary, another source of information was the legal framework and its impact on rescue chain, acute treatment and rehabilitation. Existent quality management systems, accreditations and quality assurance programs in prevention, acute treatment and rehabilitation have been searched in order to avoid any overlap with existing measures. After identifying a total of 71 quality targets according to deficits of care, recommendations for care and expert opinions in primary and secondary prevention, rescue chain, acute treatment, rehabilitation and supply of assistive equipment and therapies, respectively, the usability of instruments was tested. These instruments included case documentation, patient surveys and routine data. 14 quality targets proved to be reproducible by these instruments and were included in the recommendations for a cross-sectoral quality assurance program for stroke and TIA.

    2016-08-01

    Full Text Available Background: Stevens - Johnson syndrome (SJS and Toxic Epidermal Necrolysis (TEN are currently regarded to be same disease entity which differs only in the extent and severity of epidermal sloughing. Both are potentially life-threatening mucocutaneous immunologic reaction, which are most frequently induced by drug consumption. The epithelial destruction of skin and mucosal membrane can cause both acute as well as chronic/ long term outcomes in term of  late sequelae during the course of the disease. Sequelae often occur during the late phase of SJS/TEN and become a significant problem due its chronicity and severe degree of impairment, which leads to deterioration of quality of life for the patients. This may prevented or decreased in terms of intensity if the patient’s received prompt and sufficient topical therapy, particularly in managing lesions on the mucosa of the eye, oral, and genital. Objective : This review underlines topical therapies which could be delivered for management of mucocutaneous lesions from SJS/ TEN, aimed to prevent late sequelae due to SJS – TEN in order to improve the life quality of SJS – TEN survivors. Conclusion: SJS/ TEN frequently lead to late sequeale which includes skin, ocular, oral, and genital involvement. These sequelaes are often severe and chonic. Thus, may cause significant decrease in quality of life of SJS/TEN survivors. It is therefore most important to detect them early in order to manage them adequately. To date, we still have an impression that the specific sequelae of SJS – TEN are often late diagnosed and insufficiently treated. Finally, we want to emphasize that for mucosal involvement in particular, such as ocular, genital and oral involvement, a careful topical treatment have to be taken into special consideration in order to prevent severe late sequelae.

    Objectives: To evaluate the effectiveness of topical 5-aminolevulinic acid (ALA)- medicated photodynamic therapy (ALA PDT) for the treatment of moderate to severe acne vulgaris. Methods: Sixteen Chinese patients with moderate to severe facial acne were treated with 1-3 courses of ALA PDT. ALA cream (3%) was freshly prepared and applied to acne lesions for 3-4 h. The lesions were irradiated by a 635 nm diode laser at dose levels of 60 - 80 J/cm2 at 100 mW/cm2. Clinical assessments were conducted before and after treatment up to 3 months. Results: All patents showed response to ALA PDT. Complete clearance was seen in 10 patients (62.5%) and partial clearance in 6 patients (37.5%). One case showed recurrence after complete clearance at 2 months and another two showed recurrence after complete clearance at 3 months. However, the number of new lesions were significantly reduced. Adverse effects were minimal. Conclusions: The results of this preliminary clinical study is encouraging. ALA PDT is a simple, safe and useful therapeutic option for the treatment of moderate to severe acne. Further studies to evaluate the treatment with a larger number of patients and for a longer period of follow-up are needed.

    Recurrent keloid scarring has a significant impact on quality of life. Management is complex, particularly for scars resistant to conventional treatments and in paediatric cases where radiotherapy is not a suitable adjunct to surgical excision. We present the case of a nine-year-old African Caribbean girl with multiple large and recurrent keloid scars on both ears and bilateral sensorineural deafness. Following repeated intralesional excisions, corticosteroid and botulinum toxin injections, she continued to experience rapid recurrence of her keloids, worsening pain and pruritus. She was no longer able to wear her hearing aids because of the large size of the keloids. We employed a novel technique using topical intralesional cryotherapy, applying liquid nitrogen intraoperatively to the inside of the skin flaps immediately post-intralesional keloid excision and before wound closure. At 26-month follow-up a good aesthetic and symptomatic result was achieved, with minimal hypopigmentation, significantly reduced scar volume and significantly slowed recurrence. We discuss this case and review the current literature on the use of topical intralesional cryotherapy for keloid scarring.

  5. Topical PDT in the Treatment of Benign Skin Diseases: Principles and New Applications

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

    Laser tattoo removal using multiple passes per session, with each pass delivered after spontaneous resolution of whitening, improves tattoo fading in a 60-minute treatment time. Our objective was to evaluate the safety and efficacy of topical perfluorodecalin (PFD) in facilitating rapid effective multiple-pass tattoo removal. In a randomized, controlled study using Q-switched ruby or Nd:YAG laser, 22 previously treated tattoos were treated with 3 passes using PFD to resolve whitening after each pass ("R0 method"). In previously untreated symmetric tattoos, seven were treated over half of the tattoo with the R20 method, and the opposite half with 4 passes using PFD (R0 method); two were treated over half with a single pass and the opposite half with 4 passes using PFD (R0 method); and six treated over half with a single pass followed by PFD and the opposite half with a single pass alone. Blinded dermatologists rated tattoo fading at 1-3 months. Optical coherence tomography (OCT) imaging of whitening was performed in two tattoos. Topical PFD clinically resolved immediate whitening reactions within a mean 5 seconds (range 3-10 seconds). Tattoos treated with the R0 method demonstrated excellent fading in an average total treatment time of 5 minutes. Tattoo areas treated with the R0 method demonstrated equal fading compared to the R20 method, and improved fading compared to a single pass method. OCT imaging of whitening demonstrated epidermal and dermal hyper-reflective "bubbles" that dissipated until absent at 9-10 minutes after PFD application, and at 20 minutes without intervention. Multiple-pass tattoo removal using PFD to deliver rapid sequential passes (R0 method) appears equally effective as the R20 method, in a total treatment time averaging 5 minutes, and more effective than single pass treatment. OCT-visualized whitening-associated "bubbles," upon treatment with PFD, resolve twice as rapidly as spontaneous resolution. Copyright © 2012 Wiley

    In treating androgenetic alopecia, 5% minoxidil is a commonly used topical drug. By using electrodynamic microneedle at the same time may increase absorption of minoxidil and further stimulate hair growth. A 24-week, randomized, evaluator blinded, comparative study was performed to evaluate the efficacy of treating Chinese male androgenetic alopecia using microneedle combined with 5% minoxidil topical solution. Randomized subjects received topical 5% minoxidil (group 1, n = 20), local electrodynamic microneedle treatments (group 2, n = 20), or local electrodynamic microneedle treatments plus topical 5% minoxidil (group 3, n = 20). A total of 12 microneedle treatments were performed every 2 weeks with 2ml 5% minoxidil delivery in group 3 during each microneedle treatment. Patient receiving topical 5% minoxidil applied 1 ml of the solution twice daily over the course of the study. A total of 60 Chinese male subjects with Norwood-Hamilton type III-VI androgenetic alopecia were treated. The mean improvement in total hair density from baseline to 24 weeks was 18.8/cm 2 in group 1, 23.4/cm 2 in group 2, and 38.3/cm 2 in group 3. The hair growth in the 3 groups was significantly different (P = 0.002), but there were no significant differences in toxicity found between the 3 groups. Treatment with microneedle plus topical 5% minoxidil was associated with the best hair growth.

    Oral lichen planus and mouth dryness are common pathoses, yet not entirely understood. These two conditions may be associated, with a few studies investigating the relationship between mouth dryness and oral lichen planus providing conflicting results. None of the studies have explored the specific impact of disease treatment on mouth dryness. The purpose of this observational before and after comparison study was to examine the effect of treatment of oral lichen planus with topical corticosteroids on mouth dryness. Nineteen subjects with oral lichen planus were evaluated for the severity of xerostomia using a xerostomia inventory and a visual analogue scale. Stimulated and unstimulated whole salivary flow rates, unstimulated salivary pH and buffering capacity were also measured. All subjects were evaluated before and after treatment with topical corticosteroids. All subjects reported xerostomia before treatment with topical corticosteroids, with 79% reporting a significant improvement ( P = 0.03) after treatment. Topical corticosteroid treatment was not associated with statistically significant differences in stimulated or unstimulated salivary flow rates, unstimulated salivary pH or buffering capacity. The results of this study suggest that treatment of oral lichen planus with topical corticosteroids may decrease the severity of dry mouth symptoms.

    The American Nuclear Society Topical Meeting on the Treatment and Handling of Radioactive Wastes was held in Richland, Washington, from 19-22 April 1982. The object of the meeting was to provide a thorough assessment of the status of technology. The response to the meeting was excellent: 123 papers were presented. There were 505 registrations; 83 were from outside the USA, representing 13 countries. The large and diverse attendance provided a broad technological view and perspective. The following major points emerged from the conference: (1) In an extensive world-wide effort, techniques are being developed to cover all phases of radioactive waste management. (2) A broad and deep technological base has been developed. (3) Many adequate processes are ready for actual application while others are ready for demonstration of applicability. These demonstrations are important to further public acceptance of nuclear energy. (4) At the present level of maturity, systematic analyses should be performed to determine actual requirements for the treatment and handling of radioactive wastes. These analyses can be used to focus our research and development, and demonstration activities to achieve treatment and conditioning systems which are both appropriate and cost-effective. (author)

    We sought to understand pregnant women's product preference and likelihood of use of topical microbicides for bacterial vaginosis (BV) prevention and treatment. Pregnant women (N = 196) in a obstetrics clinic completed a survey between June 2014 and January 2015 about vaginal product use for BV. This cross-sectional study explored product preferences, likelihood of product use for BV management and father of the baby (FOB) involvement. Most participants were under 30 (68%) and underrepresented minorities (47% Hispanic, 21% African-American). Most women preferred the gel (69%). Only 30% were likely to use either product for prevention of BV; 76% if high risk for BV; 83% treatment of BV. Anticipated FOB involvement in decision-making included that 46% would ask his opinion, 38% would inform him of the decision and 7% would need approval. Most (87%) would ask the FOB for reminders and 66% for insertion help. Those under 30 were more likely to agree to ask the FOB for reminders (p Product preferences may be less critical than risk perception. Involvement of the FOB in decision-making may be vital.

    Background and aims. Oral lichen planus (OLP is a common chronic mucocutaneous disease. Patients with atrophic and erosive lichen planus often have symptoms of soreness and need proper treatment. The main therapy of OLP has been the administration of topical or systemic corticosteroids. Potent topical corticosteroids have been increasingly prescribed in the treatment of erosive lichen planus. The purpose of this study was to compare the efficacy of adcortyl ointment (triamcinolone in orabase with topical tacrolimus for the treatment of erosive oral lichen planus.

    Materials and methods. Sixty Patients with histopathologically confirmed oral lichen planus were enrolled in the study. The severity of lesions was scored from 0 to 5 according to the criteria described in a previous study. Patients were randomly given adcortyl (group A and topical tacrolimus ointment (group B and asked to apply the medication on dried lesions 4 times a day. The lesions were evaluated after 4 weeks of treatment. Visual analogue scale was used to assess the severity of pain before and after treatment. The severity scores were analyzed using the Kruskal-Wallis k-sample test.

    Results. The average score of lesions improved from 3.4 to 1.5 in patients who received adcortyl ointment and from 3.2 to 1.2 in patients who received topical tacrolimus ointment. The differences between the improvements in scores were not statistically significant in the two groups. The average pain severity in A and B groups was 8.2 and 7.8 at the beginning of treatment, and 3.5 and 3.2 at the end of treatment, respectively. There was a statistically significant reduction in pain severity in both groups.

    Conclusion. Topical tacrolimus is a safe and effective alternative therapy in the treatment of oral lichen planus.

    We used JetPeel, combined with topical minoxidil to treat patients with AGA, in order to observe whether the JetPeel can accelerate the recovery of the disease and find a new method for AGA treatment. Thirty patients who met the standard were included in the study. The patients were randomly divided into three groups. The first group was treated with JetPeel-assisted topical minoxidil. The second group received topical minoxidil monotherapy. The third group was not given any treatment. We used objective evaluation (amount and diameter of hair, oil secretion level) and subjective evaluation (hair growth score marked by dermatologist and patient) to evaluate the hair growth condition before treatment and every other month. The calculated p values of less than 0.05 were accepted as significant. All of the 30 patients finished the study. There was no difference in age, sex, and duration and severity of the disease among groups prior to treatment (p > 0.05). And there was greater improvement in scores of hair growth in the first group compared to the second and third group, which was statistically significant (p topical minoxidil monotherapy, JetPeel-assisted topical minoxidil is more effective during the treatment of androgenetic alopecia.

    Hyperkeratotic-type tinea pedis is chronic and recalcitrant to topical antifungal agents. Some topical antifungal agents are effective; however, long duration of therapy is required, which often reduce the treatment compliance of patients. To seek for short period therapy of hyperkeratotic type tinea pedis, in this study, we observed the efficacy and safety of treatment of topical terbinafine and 10% urea ointment combined oral terbinafine. Participants with hyperkeratotic type tinea pedis were randomly assigned to two groups. Patients in group I were treated with oral terbinafine for 2 weeks and topical terbinafine and 10% urea ointment for 4 weeks, whereas in group II, only the above topical agents were applied for 12 weeks. Clinical improvement rates and fungal eradication rates were compared between the two groups at 24 weeks after the initiation of treatment. The group I had stopped the topical therapy 8 weeks earlier than group II. There were no significant differences in mycological eradication rates and clinical improvement rates between the two groups, besides, no major side effects were noted in both groups. The short combination therapy with oral terbinafine was effective and safe; it should be a valuable option for patients with hyperkeratotic type tinea pedis. © 2014 Blackwell Verlag GmbH.

    Impaired skin wound healing is a significant co-morbid condition of diabetes that is caused by poor microcirculation among other factors. Hypoxia-inducible factors (HIFs) are transcription factors that mediate the effects of decreased levels of oxygen in biological environments. Inducing mild hypoxia in the tissue could promote angiogenesis, a critical step in the wound healing process in diabetic wounds. To investigate the relationship between hypoxia and diabetic wound healing, a topical treatment consisting of a HIF-activating prolyl-hydroxylase inhibitor was administered to the wounded skin of diabetic (db/db) mice. Studies were conducted in accordance with the GSK Policy on the Care, Welfare and Treatment of Laboratory Animals and were reviewed at GSK or by the ethical review process at the institution where the work was performed. The wounded area was tracked in vivo for 28 days utilizing a custom-built multimodal microscopy system. An increase in vascular density around the wounds of treated animals was observed using phase-variance optical coherence tomography (PV-OCT), in comparison to normal controls. In addition, second harmonic generation (SHG) and fluorescence lifetime imaging microscopy (FLIM) were utilized to examine the collagen regeneration and cellular metabolic activity, respectively, in the wounded skin. The utilization of these light based methods can follow metabolic and morphologic changes in the wound healing process in ways not possible with current evaluation processes. Insights demonstrated in these studies could lead to new endpoints for evaluation of the efficacy of drugs and lead to more direct ways of detecting patient response to treatment.

    Full Text Available Ravi Shrivastava, Nathalie Cucuat, Monika Rousse, Thomas Weigand, Pedro Neto, Claire Janicot, Christiane Shrivastava VITROBIO Research Institute, Issoire, France Purpose: Incidence of chronic wounds is constantly rising worldwide, but all currently available treatments are intended either to provide symptomatic relief or to assist cicatrization to some extent, but not to directly stimulate cellular growth. Physiologically, chronic wound healing simply requires cell growth to fill the injured cavity. To grow, our cells need to attach onto a cushion, called extracellular matrix (ECM, secreted by the mother cells and composed of multiple proteins. Recent scientific works prove that the concentration of certain matrix metalloproteinases (MMPs is extremely high in all chronic wounds and, because of their proteolytic nature, some MMPs completely degrade the ECM, hindering cell attachment and cell growth. The aim of this study was to identify, neutralize, and eliminate these MMPs from the wound surface so as to design an effective treatment for chronic wounds. Methods: Acute and chronic models of human epithelial and fibroblast cells were prepared on a defined ECM cushion in vitro and MMPs were added in the culture medium to identify the MMPs causing ECM disintegration for each cell type. ECM-degrading MMPs were then incubated with selected procyanidin-rich plant extracts (PCDs and cell growth was reanalyzed. Results: It was observed that: 1 multiple MMPs are involved in cellular matrix destruction; 2 ECM-destroying MMPs are specific with respect to cell type; and 3 specific PCDs may bind and neutralize selected MMPs. Conclusion: Topical application of specific plant PCDs to selectively neutralize ECM-destroying MMPs in acute and chronic wounds represents a novel approach for the treatment of superficial and deep skin wounds.

    Warts are benign proliferations of skin and mucosa caused by the human papillomavirus (HPV). Plane warts are caused by HPV types 3, 10, 28, and 41, occurring mostly in children and young adults. Among the treatment modalities, topical application of trichloroacetic acid (TCA) is age old. Potassium hydroxide (KOH) has a keratolytic effect on virus-infected cells. It is less irritating, less painful, less scar forming, and can be safely used in children too. Hence, it could be a better topical agent in the treatment of plane warts. To compare the safety and efficacy of topical 10% KOH with 30% TCA in the treatment of plane warts. Sixty consecutive patients with plane warts were randomly assigned into two arms of thirty patients each; arm A received topical 10% KOH and arm B received topical 30% TCA as a once weekly application until the complete clearance of warts or a maximum period of 12 weeks. Statistically no significant difference ( P = 0.07) was found between the objective therapeutic response to 10% KOH and 30% TCA at the end of study (12 weeks). However, subjective response to 10% KOH was better and statistically significant ( P = 0.03). There was no recurrence of warts seen on follow-up for 3 months of complete responders in both the arms. 10% KOH is found to be equally effective in the treatment of plane warts compared to 30% TCA with the advantage of faster onset of action and tendency of completely clearing warts with fewer side effects.

    Dry eye is a prevalent condition and one of the main reasons for patients to seek ophthalmic medical care. A low systemic level of omega fatty acids is a risk factor for dry eye disease (DED). There are two groups of essential fatty acids (EFAs): the omega-6 (n-6) family and the omega-3 (n-3) family. Humans evolved on a diet in which the n-6:n-3 ratio was approximately 1:1, however the current Western diet tends to be deficient in n-3 EFAs and this ratio is typically much higher (approaching 17:1). The metabolism of EFAs generates four new families of local acting mediators: lipoxins, resolvins, protectins, and maresins. These molecules have anti-inflammatory and pro-resolution properties. We present a critical overview of animal model studies and human clinical trials that have shown that dietary modification and oral supplementation could be complementary therapeutic strategies for the treatment of dry eye. Furthermore, we discuss preliminary results of the topical application of n-3 and n-6 EFAs because these molecules may act as natural anti-inflammatory agents with positive changes of the entire ocular surface system.

    Full Text Available Abstract Background The objective of this study was to identify the molecular processes responsible for the anti-lesional activity of imiquimod in subjects with actinic keratosis using global gene expression profiling. Methods A double-blind, placebo-controlled, randomized study was conducted to evaluate gene expression changes in actinic keratosis treated with imiquimod 5% cream. Male subjects (N = 17 with ≥ 5 actinic keratosis on the scalp applied placebo cream or imiquimod 3 times a week on nonconsecutive days for 4 weeks. To elucidate the molecular processes involved in actinic keratosis lesion regression by imiquimod, gene expression analysis using oligonucleotide arrays and real time reverse transcriptase polymerase chain reaction were performed on shave biopsies of lesions taken before and after treatment. Results Imiquimod modulated the expression of a large number of genes important in both the innate and adaptive immune response, including increased expression of interferon-inducible genes with known antiviral, anti-proliferative and immune modulatory activity, as well as various Toll-like receptors. In addition, imiquimod increased the expression of genes associated with activation of macrophages, dendritic cells, cytotoxic T cells, and natural killer cells, as well as activation of apoptotic pathways. Conclusion Data suggest that topical application of imiquimod stimulates cells in the skin to secrete cytokines and chemokines that lead to inflammatory cell influx into the lesions and subsequent apoptotic and immune cell-mediated destruction of lesions.

    The evolutionary radiation of dinosaurs in the Late Triassic and Early Jurassic was a pivotal event in the Earth's history but is poorly understood, as previous studies have focused on vague driving mechanisms and have not untangled different macroevolutionary components (origination, diversity, abundance and disparity). We calculate the morphological disparity (morphospace occupation) of dinosaurs throughout the Late Triassic and Early Jurassic and present new measures of taxonomic diversity. Crurotarsan archosaurs, the primary dinosaur 'competitors', were significantly more disparate than dinosaurs throughout the Triassic, but underwent a devastating extinction at the Triassic-Jurassic boundary. However, dinosaur disparity showed only a slight non-significant increase after this event, arguing against the hypothesis of ecological release-driven morphospace expansion in the Early Jurassic. Instead, the main jump in dinosaur disparity occurred between the Carnian and Norian stages of the Triassic. Conversely, dinosaur diversity shows a steady increase over this time, and measures of diversification and faunal abundance indicate that the Early Jurassic was a key episode in dinosaur evolution. Thus, different aspects of the dinosaur radiation (diversity, disparity and abundance) were decoupled, and the overall macroevolutionary pattern of the first 50Myr of dinosaur evolution is more complex than often considered.

    Full Text Available Abstract Background Retinopathy of Prematurity (ROP is a common retinal neovascular disorder of premature infants. It is of variable severity, usually heals with mild or no sequelae, but may progress to blindness from retinal detachments or severe retinal scar formation. This is a preliminary report of the effectiveness and safety of a new and original use of topical ketorolac in preterm newborn to prevent the progression of ROP to the more severe forms of this disease. Methods From January 2001 to December 2002, all fifty nine preterm newborns with birthweight less than 1250 grams or gestational age less than 30 weeks of gestational age admitted to neonatal intensive care were eligible for treatment with topical ketorolac (0.25 milligrams every 8 hours in each eye. The historical comparison group included all 53 preterm newborns, with the same inclusion criteria, admitted between January 1999 and December 2000. Results Groups were comparable in terms of weight distribution, Apgar score at 5 minutes, incidence of sepsis, intraventricular hemorrhage and necrotizing enterocolitis. The duration of oxygen therapy was significantly longer in the control group. In the ketorolac group, among 43 children that were alive at discharge, one (2.3% developed threshold ROP and cryotherapy was necessary. In the comparison group 35 children survived, and six child (17% needed cryotherapy (Relative Risk 0.14, 95%CI 0.00 to 0.80, p = 0.041. Adjusting by duration of oxygen therapy did not significantly change these results. Adverse effects attributable to ketorolac were not detected. Conclusions This preliminary report suggests that ketorolac in the form of an ophthalmic solution can reduce the risk of developing severe ROP in very preterm newborns, without producing significant adverse side effects. These results, although promising, should be interpreted with caution because of the weakness of the study design. This is an inexpensive and simple intervention that

    Currently available treatment options for impetigo are limited by either systemic side effects (for oral therapy) or lack of ease of use (for topical ointment). A novel foam formulation of minocycline for topical use may improve convenience and treatment utilization for pediatric patients with impetigo. To evaluate the safety and efficacy of topically applied minocycline foam (FMX-102 1% and 4%) in the treatment of impetigo and to determine the optimal therapeutic active ingredient concentration. In this randomized, parallel-group, double-blind, comparative clinical trial, 32 subjects aged ≥2 years with a clinical diagnosis of pure impetigo, impetigo contagiosa, or uncomplicated blistering impetigo were randomized to treatment with FMX-102 1% or 4%, twice daily for 7 days. Subjects were followed for up to 7 days post-treatment. Clinical cure, defined as ≥80% cured lesions (fully recovered lesions, visually determined by investigators), was achieved by 57.1% and 50.0% of FMX-102 1% and 4% subjects, respectively, at the end of treatment (visit 3). Clinical success, defined as the absence of lesions, or the drying or improvement of treated lesions (decrease in size of affected area, lesion number, or both), was demonstrated in 81.3% and 78.6% of FMX-102 1% and 4% subjects, respectively, following 3 days of treatment (visit 2), in 92.3% and 100% of the respective subjects at the end of treatment, and in 100% in both groups at follow-up (visit 4). Bacteriologic success rates at the end of treatment, defined as complete pathogen eradication, were 85% and 74% in the FMX-102 1% and 4% groups, respectively. The bacteriologic success rate for MRSA infections was 100% (11/11), with no recurrences. Both FMX-102 1% and 4% were considered well tolerated and safe. Topical minocycline foam may be a safe and effective new treatment option for impetigo in children, including those with MRSA. J Drugs Dermatol. 2016;15(10):1238-1243.

    Biofilms are aggregates of bacteria residing in a self-assembled matrix, which protects these sessile cells against external stress, including antibiotic therapies. In light of emerging multidrug-resistant bacteria, alternative strategies to antibiotics are emerging. The present study evaluated the activity of colloidal silver nanoparticles (AgNPs) of different shapes against biofilms formed by Staphylococcus aureus (SA), methicillin-resistant SA (MRSA), and Pseudomonas aeruginosa (PA). Colloidal quasi-spherical, cubic, and star-shaped AgNPs were synthesized, and their cytotoxicity on macrophages (THP-1) and bronchial epithelial cells (Nuli-1) was analyzed by the lactate dehydrogenase assay. The antibiofilm activity was assessed in vitro by the resazurin assay and in an in vivo infection model in Caenorhabditis elegans. Cubic and star-shaped AgNPs induced cytotoxicity, while quasi-spherical AgNPs were not toxic. Quasi-spherical AgNPs showed substantial antibiofilm activity in vitro with 96% (±2%), 97% (±1%), and 98% (±1%) biofilm killing of SA, MRSA, and PA, respectively, while significantly reducing mortality of infected nematodes. The in vivo antibiofilm activity was linked to the accumulation of AgNPs in the intestinal tract of C. elegans as observed by 3D X-ray tomography. Quasi-spherical AgNPs were physically stable in suspension for over 6 months with no observed loss in antibiofilm activity. While toxicity and stability limited the utilization of cubic and star-shaped AgNPs, quasi-spherical AgNPs could be rapidly synthesized, were stable and nontoxic, and showed substantial in vitro and in vivo activity against clinically relevant biofilms. Quasi-spherical AgNPs hold potential as pharmacotherapy, for example, as topical treatment for biofilm-related infections.

    Acute pain caused by musculoskeletal disorders is very common and has a significant negative impact on quality-of-life and societal costs. Many types of acute pain have been managed with traditional oral non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitors (coxibs). Data from prospective, randomised controlled clinical trials and postmarketing surveillance indicate that use of oral traditional NSAIDs and coxibs is associated with an elevated risk of developing gastrointestinal, renovascular and/or cardiovascular adverse events (AEs). Increasing awareness of the AEs associated with NSAID therapy, including coxibs, has led many physicians and patients to reconsider use of these drugs and look for alternative treatment options. Treatment with NSAIDs via the topical route of administration has been shown to provide clinically effective analgesia at the site of application while minimising systemic absorption. The anti-inflammatory and analgesic potency of the traditional oral NSAID diclofenac, along with its physicochemical properties, makes it well suited for topical delivery. Several topical formulations of diclofenac have been developed. A topical patch containing diclofenac epolamine 1.3% (DETP, FLECTOR(®) Patch), approved for use in Europe in 1993, has recently been approved for use in the United States and is indicated for the treatment of acute pain caused by minor strains, sprains and contusions. In this article, we review the available clinical trial data for this product in the treatment of pain caused by soft tissue injury. © 2010 Blackwell Publishing Ltd.

    Non-extensive superficial partial thickness burns constitute a major proportion of burns. Conventional treatment involves regular changing of absorptive dressings including the application of a topical antimicrobial, commonly silver sulfadiazine. A systematic review has found insufficient evidence to support or refute such antimicrobial prophylaxis. Another review compared silver sulfadiazine dressings with other occlusive and non-antimicrobial dressings and found insufficient evidence to guide practice. Other research has suggested that dressings with petrolatum gel are as effective as silver sulfadiazine. Single-center, randomized, controlled parallel group trial comparing conventional silver sulfadiazine dressings with treatment with petrolatum gel alone. Consenting adults 18-45 years old with superficial partial thickness burns≤10% total body surface area seen within 24h of the injury were randomized to daily dressing either with petrolatum gel without top dressings or conventional silver sulfadiazine treatment with gauze dressings. Primary outcomes were blinded assessment of time to complete re-epithelialization, wound infection or allergic contact dermatitis. Secondary outcomes included assessment of ease, time and pain of dressing changes. 26 patients were randomized to petrolatum and 24 to silver sulfadiazine dressings. Follow up data available for 19 in each group. Mean time to re-epithelialization was 6.2 days (SD 2.8) in the petrolatum group and 7.8 days (SD 2.1) in the silver sulfadiazine group (p=0.050). No wound infection or dermatitis was observed in either group. Scores for adherence to wound, ease of dressing removal and time required to change dressings were significantly better in the petrolatum treatment arm (ptreatment of minor superficial partial thickness burns in adults.

    The debate whether the coevolution of plants and insects or macroevolutionary processes (phylogeny) is the main driver determining the arsenal of molecular defensive compounds of plants remains unresolved. Attacks by herbivorous insects affect not only the composition of defensive compounds in plants but the entire metabolome (the set of molecular metabolites), including defensive compounds. Metabolomes are the final products of genotypes and are directly affected by macroevolutionary processes, so closely related species should have similar metabolomic compositions and may respond in similar ways to attacks by folivores. We analyzed the elemental compositions and metabolomes of needles from Pinus pinaster, P. nigra and P. sylvestris to determine if these closely related Pinus species with different coevolutionary histories with the caterpillars of the processionary moth respond similarly to attacks by this lepidopteran. All pines had different metabolomes and metabolic responses to herbivorous attack. The metabolomic variation among the pine species and the responses to folivory reflected their macroevolutionary relationships, with P. pinaster having the most divergent metabolome. The concentrations of phenolic metabolites were generally not higher in the attacked trees, which had lower concentrations of terpenes, suggesting that herbivores avoid individuals with high concentrations of terpenes. Our results suggest that macroevolutionary history plays important roles in the metabolomic responses of these pine species to folivory, but plant-insect coevolution probably constrains those responses. Combinations of different evolutionary factors and trade-offs are likely responsible for the different responses of each species to folivory, which is not necessarily exclusively linked to plant-insect coevolution.

    The treatment of dermatophytoses, including onychomycosis, has come a long way over the past few decades with the introduction of oral antifungals (e.g., terbinafine and itraconazole). However, with these advancements in oral therapies come several undesirable effects, such as kidney and liver toxicity, along with drug-drug interactions. Consequently, there is a need for new topical agents that are effective against dermatophytosis. ME1111 is a topical antifungal under development. In this study, the in vivo efficacy of ME1111 was compared to that of ciclopirox in the topical treatment of dermatophytosis caused by Trichophyton mentagrophytes using a guinea pig model. Animals were treated with the topical antifungals starting at 3 days postinfection, with each agent being applied once daily for seven consecutive days. After the treatment period, the clinical and mycological efficacies were evaluated. The data showed that both antifungals demonstrated significant clinical and mycological efficacies; however, ME1111 showed clinical efficacy superior to that of ciclopirox (46.9% and 25.0%, respectively, with a P value of <0.001). The potent efficacy of ME1111 could be attributed to its properties, such as low keratin binding. PMID:26833160

    A multicentre double-blind randomized study was carried out to compare topical ciprofloxacin and topical gentamicin in the treatment of simple non-cholesteatomatous purulent chronic otitis media. Three hundred and eight patients were included in the study, 159 treated with ciprofloxacin and 149 treated with gentamicin. The percentage of clinical success (elimination of otorrhoea) was 95% with ciprofloxacin and 94% with gentamicin (ns). Likewise, the percentage of bacteriological erradication was 96% with ciprofloxacin and 93% with gentamicin. Both drugs were well tolerated, without changes in the audiometric values. In these patients, topical ciprofloxacin shows the same efficacy as topical gentamicin without any potential ototoxic effect.

A 9-year-old Malay girl with a history of bilateral blepharokeratoconjunctivitis was regularly treated with lid scrubbing using diluted baby shampoo, fusidic acid gel, and topical steroids as well as an intermittent course of oral doxycycline for the past year. She developed acute onset bilateral eye redness associated with poor vision in her right eye. Both eyes showed marked diffuse hyperemic conjunctiva with corneal vascularization. The presence of corneal vascularization obscured the visual axis in the right eye. The condition did not improve with regular intensive lid hygiene using diluted baby shampoo, fusidic acid gel, and topical steroids. She was started on topical cyclosporin A 0.5% every 6 hours. There was a dramatic regression of corneal vascularization after 3 days on topical cyclosporin, with marked improvement in visual acuity. This is a single case in which cyclosporin improved the status of the ocular surface. A large cohort study is required to justify its effectiveness in treating blepharokeratoconjunctivitis and to test its potential as an alternative immunosuppressive agent in comparison to conventional corticosteroids.Keywords: blepharokeratoconjunctivitis, cyclosporin

    Full Text Available We reported here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

    Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa with treatment challenges for clinicians. The objective of this study is to compare the effects of cryotherapy as a new modality with topical corticosteroids as a conventional therapy in the treatment of OLP. Thirty patients with bilateral OLP lesions were selected. From each patient a lesion on one side was chosen randomly for a single session of cryotherapy with nitrous oxide gas and the lesion on the other side received triamcinolone acetonide 0.1% ointment in orabase. Treatment outcome was measured by means of an appearance score, pain score (visual analogue scale), and severity of lesions before treatment and after 2, 4 and 6 weeks of treatment. Paired samples t-test and Wilcoxon test. In both methods of treatment sign score, pain score and severity of lesions was significantly reduced in all follow-up sessions (Ptreatment outcome and relapse was not significantly different between the two treatment methods (P>0.05). Cryotherapy with nitrous oxide gas is as effective as topical triamcinolone acetonide in the treatment of OLP with no systemic side effects and needs less patient compliance. It can be considered as an alternative or adjuvant therapy in OLP patients to reduce the use of treatments with adverse effects.

    Topical treatment of onychomycoses is time consuming, cost-intensive and subject to relatively high failure rates. Light-based devices may be effective treatment modalities. Aim of this work: To compare the clinical and mycological efficacy of Nd-YAG laser versus topical terbinafine in the treatment of onychomycosis. This study included 40 patients with onychomycosis randomized to receive four sessions of Nd-YAG laser (group A) or topical terbinafine twice daily for six months (group B). Follow-up was performed monthly. Mycological examination was done at third and sixth months following the start of treatment. After six months, all patients in group A showed marked improvement, while in group B only 50% of patients showed mild to moderate improvement. In addition, by the end of six months, 80% of the patients in group A showed mycological clearance, while all patients in group B still had positive cultures. Long pulse Nd-YAG laser therapy of onychomycosis is a safe and efficient method for treating onychomycosis. It is especially beneficial in elderly, compromised and hepatopathic patients for whom other alternative treatments could present some risks.

    Oral lichen planus (OLP) is a relatively common chronic mucocutaneous inflammatory disease and a search for novel therapeutic options has been performed. We sought to compare the efficacy of laser phototherapy (LPT) to topical clobetasol propionate 0.05% for the treatment of atrophic and erosive OLP. Forty-two patients with atrophic/erosive OLP were randomly allocated to two groups: clobetasol group (n=21): application of topical clobetasol propionate gel (0.05%) three times a day; LPT group (n=21): application of laser irradiation using InGaAlP diode laser three times a week. Evaluations were performed once a week during treatment (Days 7, 14, 21, and 30) and in four weeks (Day 60) and eight weeks (Day 90) after treatment. At the end of treatment (Day 30), significant reductions in all variables were found in both groups. The LPT group had a higher percentage of complete lesion resolution. At follow-up periods (Days 60 and 90), the LPT group maintained the clinical pattern seen at Day 30, with no recurrence of the lesions, whereas the clobetasol group exhibited worsening for all variables analyzed. These findings suggest that the LPT proved more effective than topical clobetasol 0.05% for the treatment of OLP.

    Ecomorphology studies focus on understanding how anatomical and behavioral diversity result in differences in performance, ecology, and fitness. In mammals, the determinate growth of the skeleton entails that bite performance should change throughout ontogeny until the feeding apparatus attains its adult size and morphology. Then, interspecific differences in adult phenotypes are expected to drive food resource partitioning and patterns of lineage diversification. However, Formal tests of these predictions are lacking for the majority of mammal groups, and thus our understanding of mammalian ecomorphology remains incomplete. By focusing on a fundamental measure of feeding performance, bite force, and capitalizing on the extraordinary morphological and dietary diversity of bats, we discuss how the intersection of ontogenetic and macroevolutionary changes in feeding performance may impact ecological diversity in these mammals. We integrate data on cranial morphology and bite force gathered through longitudinal studies of captive animals and comparative studies of free-ranging individuals. We demonstrate that ontogenetic trajectories and evolutionary changes in bite force are highly dependent on changes in body and head size, and that bats exhibit dramatic, allometric increases in bite force during ontogeny. Interspecific variation in bite force is highly dependent on differences in cranial morphology and function, highlighting selection for ecological specialization. While more research is needed to determine how ontogenetic changes in size and bite force specifically impact food resource use and fitness in bats, interspecific diversity in cranial morphology and bite performance seem to closely match functional differences in diet. Altogether, these results suggest direct ecomorphological relationships at ontogenetic and macroevolutionary scales in bats. © The Author 2016.

    Anti-VEGF agents (Bevacizumab, Ranibizumab and Aflibercept seem to have a higher efficiency and efficacy for corneal NV treatment. Both subconjunctival therapy and topical therapy of bevacizumab prohibit corneal NV, while early treatment with subconjunctival administration of ranibizumab may successfully reduce corneal NV. Therefore, establishment of safe doses is highly important before these drugs can be involved in the clinical setting. Further investigations and studies are highly warranted to adjust the dose and route of administration for the antibodies directed against VEGF to be the key therapeutic agents in the corneal NV treatment.

    Full Text Available Joint pain is one of the most common complaints with many possible causes.Some medicines used for joint pain relief such as NSAIDs have substantial and frequent side effects. Topical route possibly reduces adverse reactions by maximizing local delivery and minimizing systemic toxicity. Throughout history, plants have been the most important sources of medicines for human health and Iranian Traditional Medicine (ITM is well known for its extensive use of herbal medicines to treat diseases accompanied with joint pain for centuries. In the present study, the plants used topically for relieving joint pain in ITM were searched. Moreover, their pharmacological effectiveness in modern medicine was reviewed. The terms “Waja mafasil” (joint pain, “Waja-ol-mafasil” (joint pain, “Irq-on-nasa” (sciatica, “Waja-ol-warik” (coxalgia, ‘Waja-ol-zahr” (back pain, “Waja-ol-rakbah” (knee pain and “Niqris” (gout were searched in three important Iranian traditional books including “Canon”, “Al-Hawi” and “Tohfat al-mu’minin” and topical preparations introduced as “Tela” and “Zemad” were selected. The scientific literatures were searched for their effectiveness related to the analgesic and anti-inflammatory activities. Thirty five plants were selected on the basis of their topical use to relief joint pain. Among these plants, 22 species have been found to exhibit anti-inflammatory and analgesic activities.

    Full Text Available Regardless the psoriasis subtype, up to 79% of people with this skin condition present scalp involvement, which is often the first site to show symptoms of the disease. In addition to being itchy, the red and scaly lesions are usually easy to see, and may be embarrassing. Topical therapy is usually the first line of treatment; however the wide array of available interventions can make the choice difficult, and may even lead to an inadequate treatment. The objective of this review was to evaluate the efficacy and safety of topical treatments for scalp psoriasis. A systematic review was performed according to the methodology recommended by Cochrane in order to evaluate the clinical severity of psoriasis, quality of life, and adverse events that led to treatment discontinuation. To evaluate this, 59 studies were included, with a total of 11 561 participants, and 15 comparisons were made between the various drugs and application vehicles tested. The principal conclusion is that corticosteroids of high or very high potency are more effective than vitamin D. The combination of a corticosteroid with vitamin D has only a marginal benefit over corticosteroid monotherapy, but is superior to vitamin D alone. Given the similar safety profile and only marginal benefit of the combination of corticosteroid with vitamin D over the corticosteroid alone, topical corticosteroid monotherapy appears to be fully acceptable for short-term therapy of scalp psoriasis.

    Full Text Available Background: One of the preservative treatments of knee osteoarthritis is the use of topical medications. This study is aimed to clinically evaluate the effect of topical products containing essential oils of rosemary and lavender herbs on the treatment of patients with osteoarthritis of the knee. Materials and Methods: Rosemary and lavender essential oils were prepared by steam distillation method and inserted into the ointment with the hydrophilic base. In this study, 15 patients with knee osteoarthritis were treated with this ointment for three months. The results were assessed using WOMAC and Lequesne indices and were evaluated by the Wilcoxon statistical test.Results: At the week of admission to the hospital, mean WOMAC index was equal to 71.4, mean Lequesne index was equal to 18 and the average time of passing through the distance of fifty feet by patients was equal to 19.4. After 4, 8 and 12 weeks, all these indices significantly decreased (p≤ 0.05. The WOMAC questionnaire denotative survey also showed that the pain and physical function at the 4th, 8th and 12th weeks were significantly less than the first week of admission (p≤ 0.05, but there was no significant difference as far as joint stiffness is concerned.Conclusion: Topical application of essential oils of rosemary and lavender herbs in a hydrophilic ointment base can be useful as a preservative treatment for the patients with knee osteoarthritis.

    Leishmaniasis is a protozoan zoonotic parasitic infection with cutaneous, mucocutaneous, and visceral manifestations. Israel is endemic for cutaneous leishmaniasis, which is a self-limited disease but is associated with scarring, which is often a source of psychological and social burden for patients. Scars can be especially devastating for children and teenagers. A wide range of physical and medical approaches is used to treat cutaneous leishmaniasis, among which intralesional injections of sodium stibogluconate rank among the most frequently used. Unfortunately, despite being effective, this therapeutic modality can be very painful. Fractional ablative laser creates a controlled mesh-like pattern of tissue ablation in the skin that promotes dermal remodeling and collagen production while at the same time facilitating enhanced delivery of topically applied medications. Patients were treated with fractional ablative carbon dioxide laser followed by immediate topical application of sodium stibogluconate. All children were diagnosed with cutaneous leishmaniasis prior to treatment initiation.. Ten children were treated. One leishmania tropica-positive girl failed to respond. The other nine patients achieved clinical cure and demonstrated good to excellent final cosmesis. Self-rated patient satisfaction and tolerance were high No adverse effects were observed or reported during treatment. Fractional ablative carbon dioxide laser followed by topical sodium stibogluconate application appears to be a safe and promising treatment for cutaneous leishmaniasis infection in children. Future controlled studies are required to validate these findings and compare this technique with traditional approaches. © 2018 Wiley Periodicals, Inc.

    Male pattern hair loss is widespread around the world. Its prevalence indicates the importance of finding the best treatment modalities. This study evaluates the efficacy and safety of minoxidil 5% topical foam in male pattern hair loss treatment and patient satisfaction. This study was a before-and-after trial on 17 male patients with male pattern hair loss. Subjects were instructed to apply one capful (1 ml) of minoxidil 5% topical foam on the scalp daily for 6 months. Efficacy was assessed through hair counts, subject assessment, and global photographic review. Seventeen male volunteers were recruited, and three volunteers were withdrawn; 14 participated in the trial for 16 weeks, and 12 continued up to 24 weeks. The average hair count with a camera at week 16 (181.87 ± 52.42) and week 24 (194.58 ± 62.82) and with an eye count at week 16 (62.57 ± 15.28) and week 24 (69.91 ± 15.61) increased significantly compared to the baseline after intervention. This study confirmed that minoxidil 5% topical foam is a safe and effective treatment for MPHL. The effect of it is evident after 24 weeks of use.

    The aim of this study is to compare the effectiveness of low-level laser irradiation to traditional topical fluoride treatment for treatment choices of dentinal hypersensitivity following scaling and root planing. The experimental group (15 patients) was treated with low-energy-level diode laser at each site of dentinal hypersensitivity following scaling and root planning. The control group (15 patients) received topical fluoride treatment (protective varnish for desensitization). All the patients were treated at baseline visit, and then at day 2 and 4 after the initial treatment; the pain was subjectively assessed by the patients as strong, medium, medium low, low, or no pain. Total absence of the dental hypersensitivity was reported in 26.66% of the examined group even after the second visit, compared to the control group where complete resolution of the hypersensitivity was not present after the second visit in any of the treated cases. Complete absence of pain was achieved in 86.6% of patients treated with laser and only in 26.6% in the fluoride treated group, after the third visit. Based on our findings, we conclude that low-energy biostimulative laser treatment can be successfully used for treatment of dental hypersensitivity following scaling and root planing.

    Current treatments for high-grade cervical intraepithelial neoplasia (CIN2/3) are mainly excisional procedures, which are associated with significant side effects and pose risks for future pregnancies. An effective and safe therapy is needed to reduce the requirement for surgical interventions in women of reproductive age. This review looks at the pharmacokinetic and clinical data for topical hexaminolevulinate (HAL) photodynamic therapy (PDT), which is currently entering late phase clinical trials for high-grade CIN. The authors include published studies in patients and volunteers but laboratory and animal studies have been excluded as have studies on other porphyrins such as Photofrin, 5-aminolevulinic acid, methyl aminolevulinate and studies reporting other clinical applications for HAL. Topical HAL PDT has potential as a non-surgical tissue-preserving treatment for CIN and persistent oncogenic human papilloma virus infections. HAL PDT selectively treats the entire epithelial sheet, without the tissue destruction seen in excisional procedures. The authors believe that this treatment could replace surgery in a large proportion of patients. It would be of particular value to the high percentage of women who are interested in future child-bearing. If the treatment is approved, it is very likely that physicians will want to use this treatment, as many patients will be keen to consider a non-surgical option.

    2018-01-01

    Full Text Available Simultaneous or sequential, planned administration of ipilimumab could significantly enhance the antitumor effects of nivolumab in advanced melanoma patients. On the other hand, the efficacy of ipilimumab for nivolumab-resistant advanced melanoma is extremely poor. Therefore, additional supportive therapy for anti-PD-1 antibody therapy-resistant advanced melanoma has been widely investigated. In this report, we describe a case of multiple in-transit melanomas developing in a nivolumab-resistant patient successfully treated with ipilimumab in combination with imiquimod. Our present case suggested a possible therapy for nivolumab-resistant multiple in-transit melanomas using ipilimumab in combination with topical imiquimod.

    2012-06-01

    Headache after administration of electroconvulsive therapy (ECT) is common, affecting approximately half of patients treated. Post-ECT headache is typically treated with acetaminophen or nonsteroidal anti-inflammatory drugs but occasionally requires agents such as sumatriptan, opioids, or β-blockers. We report on a patient whose severe post-ECT headaches responded completely to methyl salicylate ointment, applied to the area of his temporalis and masseter muscles. Topical methyl salicylate is generally well tolerated and may be a viable option for some patients with post-ECT headache.

    Full Text Available Background: Peptic ulcers are among the most common causes of upper gastrointestinal (GI bleeding in children. The standard care for GI bleeding is endoscopy for diagnostic and therapeutic purposes. We aimed to assess the effect of topical tranexamic acid (TXA via endoscopic procedures in children with GI bleeding caused by bleeding ulcers. Procedure: In this randomised controlled trial, 120 children were evaluated by diagnostic procedures for GI bleeding, of which 63 (30 girls, 33 boys aged 1-month to 15 years were recruited. The patients were randomly divided into case and control groups. In the case group, TXA was administered directly under endoscopic therapy. In the control group, epinephrine (1/10,000 was submucosally injected to the four quadrants of ulcer margins as the routine endoscopic therapy. In both groups, the patients received supportive medical therapy with intravenous fluids and proton pump inhibitor drugs. Results: The mean ± standard deviation age of the children was 5 ± 2.03 years. Rebleeding occurred in 15 (11.4% and 21 (9.8% patients in the case and control groups, respectively (P = 0.50. The frequency of blood transfusion episodes (P = 0.06 and duration of hospital stay (P = 0.07 were not statistically different between the groups. Conclusion: Using topical TXA via endoscopic procedures may be effective in cases of GI bleedings caused by active bleeding ulcers. In order to establish this therapeutic effect, a large number of clinical studies are needed.

    To evaluate the efficacy and safety of topical diquafosol ophthalmic solution for treatment of dry eye. Randomized clinical trials (RCTs) from MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) were identified to evaluate the efficacy and safety of topical administration of diquafosol to patients with dry eyes. Data evaluation was based on endpoints including Schirmer test, tear film break-up time, ocular surface staining score, subjective symptom score, and adverse events. A total of 8 RCTs involving 1516 patients were selected based on the prespecified criteria. Significant improvement of Schirmer test values and tear film break-up time were reported in 40% (2 of 5) and 80% (4 of 5) studies, respectively. Ocular surface staining scores significantly decreased in 100% (fluorescein corneal staining, 6 of 6; Rose Bengal corneal and conjunctival staining, 4 of 4) RCTs. Symptoms significantly improved in 75% (6 of 8) RCTs in patients with dry eyes. No severe adverse events were reported with the concentration of diquafosol from 0.5% to 5%. Heterogeneity in study design prevented meta-analysis from statistical integration and summarization. Topical diquafosol seems to be a safe therapeutic option for the treatment of dry eye. The high variability of the selected RCTs compromised the strength of evidence and limits the determination of efficacy. However, the topical administration of diquafosol seems to be beneficial in improving the integrity of the epithelial cell layer of the ocular surface and mucin secretion in patients with dry eyes. This review indicates a need for standardized criteria and methods for evaluation to assess the efficacy of diquafosol in the future clinical trials.

    The in vivo efficacy of terbinafine was compared to lanoconazole and luliconazole in the topical treatment of dermatophytosis caused by Trichophyton mentagrophytes using a guinea pig model. Topical antifungal treatment commenced three days post-infection, and each agent was applied once daily for seven consecutive days. Upon completion of the treatment period, evaluations of clinical and mycological efficacies were performed, as was scanning electron microscopy (SEM) analyses. Data showed that while all tested antifungals demonstrated significant mycological efficacy in terms of eradicating the fungi over untreated control, terbinafine and luliconazole showed superior clinical efficacy compared to lanoconazole (P-values Terbinafine demonstrated the highest clinical percent efficacy. SEM analysis revealed hairs from terbinafine and lanoconazole-treated animals had near complete clearance of fungi, while samples from luliconazole-treated animals were covered with debris and few conidia. This study demonstrates that, in general, terbinafine possessed similar efficacy to lanoconazole and luliconazole in the treatment of dermatophytosis. Terbinafine tended to have superior clinical efficacy compared to the azoles tested, although this difference was not statistically significant against luliconazole. This apparent superiority may be due to the fungicidal activity of terbinafine compared to the fungistatic effect of the other two drugs.

    In the field of veterinary dermatology dermatophytosis is one of the most frequently occurring infectious diseases, therefore its treatment should be effective, convenient, safe and inexpensive. The aim of this study was to evaluate the efficacy of newly developed topical formulations in the treatment of cats with dermatophytosis. Evaluation of clinical efficacy and safety of terbinafine and econazole formulations administered topically twice a day was performed in 40 cats. Cats, suffering from the most widely spread Microsporum canis-induced dermatophytosis and treated with terbinafine hydrochloride 1% cream, recovered within 20.3±0.88 days; whereas when treated with econazole nitrate 1% cream, they recovered within 28.4±1.14 days. A positive therapeutic effect was yielded by combined treatment with local application of creams and whole coat spray with enilconazole 0.2% emulsion "Imaverol". Most cats treated with econazole cream revealed redness and irritation of the skin at the site of application. This study demonstrates that terbinafine tended to have superior clinical efficacy (p<0.001) in the treatment of dermatophytosis in cats compared to the azole tested.

    The first World Congress on Tourette Syndrome and Tic Disorders was held in London, June 2016 by the Tourette Association of America, Tourettes Action (UK), and the European Society for the Study of Tourette Syndrome. Presentations arising from large-scale collaborative projects were an important component of the scientific programme. This article focuses on areas raised in the hot topics session and two moderated debates, which covered emerging research in etiology and treatment. The hot topics ranged across genetics, arguably including the first confirmed Tourette Syndrome (TS) susceptibility gene NRXN1, neurocognition, and neurophysiology, including the possibility of a neurocognitive endophenotype for TS and the use of depth and cortical surface electrodes to investigate the neurophysiology of tics on the background of the evolving field of deep brain stimulation (DBS), to novel treatment approaches such as dental orthotics and an online behavioral intervention. The debates aired controversies in treatment; pharmacotherapy vs. behavioral treatment and the place of medical cannabinoids. These sessions demonstrate the vibrancy of a field that has considerably expanded in the last decade, the significant progress that has been made, and the direction that some of the most fruitful next phases of research will take.

    Molluscum contagiosum is the most common skin infection in children. One topical treatment used for Molluscum contagiosum is potassium hydroxide. The objective of this study was to compare the efficacy of potassium hydroxide topical treatment at different concentrations with that of placebo in terms of complete clearing of Molluscum contagiosum lesions and to assess the safety and tolerance of potassium hydroxide topical treatment. This was a double-blind randomized clinical trial of three treatments (potassium hydroxide 10%, potassium hydroxide 15%, placebo) applied once daily up to complete clearing of lesions (maximum duration 60 days) in 53 children aged 2-6 years in primary health care pediatric offices in Catalonia, Spain. In the intention-to-treat analysis, potassium hydroxide 10% (58.8%, P = .03) and potassium hydroxide 15% (64.3%, P = .02) had efficacy superior to that of placebo (18.8%). The number of Molluscum contagiosum lesions was significantly reduced with potassium hydroxide 10% and 15%. The main efficacy outcome was achieved in 58.8% of children in the potassium hydroxide 10% group (P = .03 vs placebo) and in 64.3% of children in the potassium hydroxide 15% group (P = .02 vs placebo). Potassium hydroxide 10% and 15% were not significantly different in efficacy from each other. Potassium hydroxide 10% and placebo were better tolerated than potassium hydroxide 15%. No adverse events were reported during the study period. Potassium hydroxide 10% and 15% demonstrated high rates of efficacy in clearing Molluscum contagiosum lesions, with potassium hydroxide 10% being better tolerated. © 2018 Wiley Periodicals, Inc.

    Senile purpura presents itself as a largely unexplored challenge as it has been long thought of as a benign condition without long-term health sequelae. It is becoming increasingly accepted that skin aging not only results in cosmetic disturbances, but as a functional ones. With modern increases in lifespan, skin atrophy associated with solar damage is presenting as a clinically significant inability to mechanically protect patients. This chronic cutaneous insufficiency/fragility syndrome was recently termed dermatoporosis and senile purpura appears to be a visible marker of early stage dysfunction. To examine the effects of topically human epidermal growth factor on the clinical presence of senile purpura and its effect on skin thickness as measured via cutaneous ultrasound. Six subjects applied human epidermal growth factor morning and night for six weeks. Clinical outcomes were evaluated by comparing initial clinical photos to 6-week photos and performing a blinded investigator's global assessment (IGA). Skin thickness was evaluated via cutaneous ultrasound measurement. Ultrasound measurements indicated a mean skin thickening of 195.2 ± 35.7 um (SEM) over 6 weeks. The average number of purpuric lesions decreased from 15 ± 4.6 (SEM) to 2.3 ± 0.7 (SEM) over that same period. Senile purpura presents itself as a cosmetic disturbance posing significant psychological distress and serves as a marker of the severity of skin thinning. In this study, we demonstrate that topical h-EGF diminishes the appearance of senile purpura by thickening skin and may help prevent the development of late stage dermatoporosis.

  1. PRODUCTION WELL WATER SHUT-OFF TREATMENT IN A HIGHLY FRACTURED SANDSTONE RESERVOIR; TOPICAL

    2001-01-01

    As domestic oil and gas fields approach maturity or even abandonment, new methods are being tested to add life to the fields. One area being addressed is the reduction of water production to extend the economic life of a field. In many fields a very common problem is permeability heterogeneity from matrix variations, fractures, or both. Conventional procedures to remediate high water rates in fractured networks, including cement squeezing, openhole packers, and liners are generally unsuccessful. The objective of this project was to test the viability of using sequential treatment of a production well with a cross-linked polymer to restrict water production from highly permeable and fractured zones. The field used for testing was the Ashley Valley field in northeastern Utah. The process proposed for testing in this field was the sequential application of small batches of a cross-linked polymer, chromium (III) polyacrylamide polymer (Marcit(trademark)). First, the highest permeability fractures were to be blocked, followed progressively by smaller fractures, and finally the higher permeability matrix channels. The initial application of this polymer in September 1997 in the Ashley Valley (AV) well No.2 did increase oil production while decreasing both water production and the relative permeability to water. The successive application of the polymer was considered as a method to increase both daily and ultimate oil production and reduce produced water. The second polymer treatment was conducted in October 1999 in AV No.2. The treatment consisted of 4,994 barrels of 1,500-mg/l to 9,000-mg/l polymer at surface injection pressures no higher than 380 psig. During injection, four offset wells showed polymer breakthrough and were shut in during the remaining treatment. Present oil and water production rates for AV No.2 are 14 BOPD and 2,700 BWPD, which is a 44% decrease in the oil rate and a 40% reduction in water from the rates after the first treatment. The decrease in

    A 1.5-year-old castrated male domestic shorthair cat presented with a 2 month history of progressive nasal swelling and hyporexia. Minimal improvement prior to referral was achieved with a course of antibiotics and glucocorticoids. Cytology of an ulcerative lesion on the dorsal aspect of the nose was consistent with a diagnosis of phaeohyphomycosis. The cat achieved static disease for 6 weeks following initiation of itraconazole but developed epistaxis at 9 weeks. CT of the head demonstrated nasal and frontal sinus involvement. Nasal biopsy and culture identified infection with a Cladophialophora species not previously reported to cause disease. Initial response to a combination of itraconazole and terbinafine was noted, but owing to severe thrombocytopenia this combination was discontinued. Voriconazole was used but discontinued because of adverse side effects. Posaconazole treatment was offered throughout the clinical course but rejected owing to financial constraints and an uncertain response to medical therapy. Rhinotomy with debulking of diseased tissue and topical malachite green treatment was performed. Following the procedure itraconazole was continued and the cat has had no recurrence for over 1 year. Infections by Cladophialophora species have been reported in veterinary species, including cats. The specific fungal organism isolated from this cat has not been previously reported to cause disease in humans or animals and has only been described in the mangroves of Brazil. Furthermore, this is the first report to describe the use of topical malachite green as a treatment for refractory phaeohyphomycosis.

    We have previously reported that the topical application of erythropoietin (EPO) to cutaneous wounds in rats and mice with experimentally induced diabetes accelerates their healing by stimulating angiogenesis, reepithelialization, and collagen deposition, and by suppressing the inflammatory response and apoptosis. Aquaporins (AQPs) are integral membrane proteins whose function is to regulate intracellular fluid hemostasis by enabling the transport of water and glycerol. AQP3 is the AQP that is expressed in the skin where it facilitates cell migration and proliferation and re-epithelialization during wound healing. In this report, we provide the results of an investigation that examined the contribution of AQP3 to the mechanism of EPO action on the healing of burn wounds in the skin of pigs with experimentally induced type 1 diabetes. We found that topical EPO treatment of the burns accelerated their healing through an AQP3-dependent mechanism that activates angiogenesis, triggers collagen and hyaluronic acid synthesis and the formation of the extracellular matrix (ECM), and stimulates reepithelialization by keratinocytes. We also found that incorporating fibronectin, a crucial constituent of the ECM, into the topical EPO-containing gel, can potentiate the accelerating action of EPO on the healing of the burn injury. © 2017 by the American Diabetes Association.

    Full Text Available Aim: To compare the efficacy and safety of Olopatadine hydrochloride (0.1% with Cyclosporine A ophthalmic solution (0.05% in treating the signs and symptoms of VKC. Material and Method: Twenty-five patients with VKC were included in a prospective study. One eye of each patient was treated with Olopatadine while the other eye was treated with Cyclosporine A. Subjective symptoms of the patients such as itching, tearing, foreign body sensation, and mucus discharge were recorded and scored. The objective signs, such as the presence of giant papillae on the tarsal conjunctiva, bulbar conjunctival hyperemia, keratitis, limbal hypertrophy, corneal vascularization, and conjunctival cicatrization, were scored. Results: There was no significant difference between the Olopatadine group and the Cyclosporine A group regarding subjective symptoms at the 3rd, 6th, 12th, and 18th month. There was a significant improvement in the subjective symptoms of both groups. No significant difference was seen between the groups with regard to objective signs. A significant improvement was observed in the Cyclosporine group in the late period of the study. Discussion: In long-term therapy of VKC, similar effects were seen regarding improvement in the subjective symptoms during the use of topical Olopatadine and Cyclosporine A. In terms of improvement regarding the objective signs, Cyclosporine A was seen to be more effective in the late period.

    The auricle is a frequently injured part of the head and neck during thermal injury leading to ear deformity. The burned ear represents one of the most difficult problems for reconstructive surgeons. Mafenide acetate is a topical agent used routinely for these patients, but it has some disadvantages including painful application and allergic rash. Some authors have reported the healing effect and antibacterial activity of honey. The study reported here was undertaken to compare the effect of honey and mafenide acetate on auricular burn in rabbit. In our study, although the pathologic score of the honey group was better than that of the mafenide group both on 14 and 21 days after burning, it was not statistically significant. In the mafenide acetate group, deep complication of burn (chondritis) was significantly lower than that of the honey group. In conclusion, in contrast to healing and antibiotic activity reported for honey, it may have failure in preventing deep bacterial complications of wound (like chondritis). So in deep wounds, the use of honey as dressing is not recommended. Copyright © 2011 Elsevier Inc. All rights reserved.

Study Design: Randomized controlled trial. Place and Duration of Study: Ophthalmology department of HIT Hospital Taxila, from Oct 2014 to May 2015. Material and Methods: The patients with keratoconjunctivitis sicca (KCS) were selected from outpatient and divided in two treatment groups. The dry eye disease was defined according to criteria set by International task force for dry eye disease (ITF). The group I was treated with 0.05 percent cyclosporine drops while group-II was treated with 0.1 percent fluromethalone eye drops three times a day after informed written consent. The patients were followed up after three months and six months. Results: At the start of treatment 94 patients were placed in two treatment groups (n=47 in each group) and all the patients with KCS were graded according to severity following rules set by ITF. There were 46 patients in grade III (severe) KCS and 20 patients in grade IV (very severe) KCS. At the end of study only 24 were in grade II (moderate) KCS and 2 in grade III KCS. Of these only 5 patients in grade II and none in grade III were in treatment group I (cyclosporine). The remaining 19 patients in grade II and 5 patients in grade III KCS belonged to group II (fluromethalone). Conclusion: Cyclosporine eye drops are better than fluromethalone in treatment of keratoconjunctivitis sicca. (author)

    Atopic dermatitis affects 3-15% of the general dog population and it has been diagnosed by veterinarians up to 58% of dogs affected with skin disease. It is usually a life-long pathology which can be controlled, but it can be seldom cured. The present investigation describes a case study in which lactoferricin and verbascoside are part of a formulation to obtain a dermatological lotion for canine dermatitis treatment. The study was an open-label trial design of two-week treatment. Thirty-eight dogs (23 females and 15 males), with atopic dermatitis and secondary bacterial or yeast overgrowth have been included. During treatment period the total clinical score progressively decreased associated with an improvement in clinical signs. No adverse effects were reported in any of the treated dogs. The present research suggests that daily applications of tested emulsion are effective in reducing bacterial overgrowth and clinical signs in skin folds and atopic dermatitis.

    Full Text Available Abstract Background Leishmaniasis is an endemic disease in Iran. Although many treatments have been suggested for this disease, there hasn't been an effective and safe treatment yet. Regarding the healing effect of honey in the chronic ulcers and its reported therapeutic effect in cutaneous leishmaniasis, we performed a study to better evaluate the efficacy of honey in cutaneous leishmaniasis and its final scar. Methods In a prospective clinical trial, 100 patients with confirmed cutaneous leishmaniasis were selected and randomized into 2 groups. Group A were treated with topical honey twice daily along with intralesional injection of glucantime once weekly until complete healing of the ulcer or for maximum of 6 weeks. Group B were treated with intralesional injection of glucantime alone until complete healing of the ulcer or for a maximum of 6 weeks, too. The patients were followed for 4 months. The collected data were analyzed statistically using statistical tests including Chi-square, Mann Whitney and Kaplan – Mayer tests. Results In this study, 45 patients that had cutaneous leishmaniasis were treated with intralesional glucantime alone and 45 patients were treated with topical honey and glucantime . Ten patients left out the study. In the glucantime alone treated group, 32 patients (71.1% had complete cure whereas in the group treated with both glucantime & topical honey, 23 patients (51.1% achieved complete cure. This difference was significant statistically (p = 0.04. Conclusion Further studies to better clarify the efficacy of honey in cutaneous leishmaniasis is needed. We suggest that in another study, the efficacy of honey with standardized level of antibacterial activity is evaluated against cutaneous leishmaniasis.

    The present study aimed to evaluate the acute locally injurious property of hydroxyl radical generation system by photolysis of H(2)O(2), which is a new disinfection system for the treatment of periodontitis developed in our laboratory. Firstly, generation of the hydroxyl radical by a test device utilizing the photolysis of H(2)O(2) was confirmed by applying an electron spin resonance (ESR)-spin trapping technique. Secondly, the bactericidal effect of the device was examined under a simulant condition in which Staphylococcus aureus suspended in 1 M H(2)O(2) was irradiated with laser light emitted from the test device, resulting in substantial reduction of the colony forming unit of the bacteria within a short time as 2 min. Finally, acute topical effect of the disinfection system on rat oral mucosa and wounded skin was evaluated by histological examination. No abnormal findings were observed in the buccal mucosal region treated three times with 1 M H(2)O(2) and irradiation. Similarly, no abnormal findings were observed during the healing of skin treated with 1 M H(2)O(2) and irradiation immediately after wounding. Since topical treatment with the novel disinfection technique utilizing the photolysis of H(2)O(2) had no detrimental effect on the oral mucosa and the healing of full thickness skin wounds in rats, it is expected that the acute locally injurious property of the disinfection technique is low.

    Ubiquinone (coenzyme Q10, Q10) represents an endogenously synthesized lipid-soluble antioxidant which is crucial for cellular energy production but is diminished with age and under the influence of external stress factors in human skin. Here, it is shown that topical Q10 treatment is beneficial with regard to effective Q10 replenishment, augmentation of cellular energy metabolism, and antioxidant effects. Application of Q10-containing formulas significantly increased the levels of this quinone on the skin surface. In the deeper layers of the epidermis the ubiquinone level was significantly augmented indicating effective supplementation. Concurrent elevation of ubiquinol levels suggested metabolic transformation of ubiquinone resulting from increased energy metabolism. Incubation of cultured human keratinocytes with Q10 concentrations equivalent to treated skin showed a significant augmentation of energy metabolism. Moreover, the results demonstrated that stressed skin benefits from the topical Q10 treatment by reduction of free radicals and an increase in antioxidant capacity. © 2015 International Union of Biochemistry and Molecular Biology.

    Oral lichen planus is a chronic inflammatory mucocutaneous disease. Topical use of steroids and other immuno-modulating therapies have been tried for this intractable condition. Nowadays, tacrolimus ointment is used more commonly as a choice for treatment. However, a number of discussions have taken place after tacrolimus was reported to be carcinogenic. This report describes a patient who applied tacrolimus ointment to the lower lip after being diagnosed with oral lichen planus in 2008, and whose lesion developed squamous cell carcinoma in 2010. Since the relationship between tacrolimus and cancer development has been reported in only a few cases, including this case report, the clinician must be careful selecting tacrolimus as a second-line treatment for oral lichen planus.

    The present study was designed to develop a nanoemulsion formulation of Amphotericin B (AmB) for the treatment of skin candidiasis and aspergillosis. Several ingredients were selected on the basis of AmB solubility and compatibility with skin. The formulation that exhibited the best properties was selected from the pseudo-ternary phase diagram. After physicochemical characterization its stability was assessed. Drug release and skin permeation studies were also accomplished. The antifungal efficacy and skin tolerability of developed AmB nanoemulsion was demonstrated. Finally, our results showed that the developed AmB formulation could provide an effective local antifungal effect without theoretical systemic absorption, based on its skin retention capacity, which might avoid related side effect. These results suggested that the nanoemulsion may be an optimal therapeutic alternative for the treatment of skin fungal infections with AmB. Copyright © 2017 Elsevier Inc. All rights reserved.

    Rectal sucralfate has been reported to deliver clinical improvement in haemorrhagic radiation proctitis, but patients with active proctitis find the enema suspension difficult to retain thus reducing compliance and effectiveness. We describe a novel method of rectal administration via a low-volume sucralfate paste and report its results in a series of 23 patients. Patients with rectal bleeding occurring more than 6 months after radiotherapy were shown how to prepare and self-administer sucralfate paste enemas (SPEs) twice daily for 6 weeks. The SPE was prepared using two sucralfate 1-g tablets mixed with 4.5 ml of water in an enema applicator producing a low-volume paste. The clinical response was evaluated by comparison of pre- and posttreatment clinical proctitis scores (Radiation Therapy Oncology Group/European Organisation for Research and Treatment of Cancer). Eighteen male (postprostatic radiotherapy) and five female (postcervical radiotherapy) patients with a median age of 67 (32-75) years were included. The median interval between pelvic irradiation and SPE treatment was 24 (7-69) months. Twenty-two patients had full clinical scoring, of whom 16 (73%) demonstrated clinical improvement. Six (27%) had neither clinical improvement nor deterioration. Seven (32%) had resolution of all symptoms. Most patients demonstrated clinical improvement. This initial experience of the sucralfate paste enema may provide the basis for a prospective study of its effectiveness in the treatment of haemorrhagic radiation proctitis.

    SSc is a chronic progressive disorder of unknown aetiology characterized by excess synthesis and deposition of collagen and other extracellular matrix components in a variety of tissues and organs. Localized scleroderma (LS) differs from SSc in that with LS only skin and occasionally subcutaneous tissues are involved. Although rarely life threatening, LS can be disfiguring and disabling and, consequently, can adversely affect quality of life. There is no known effective treatment for LS, and various options, including, as examples, corticosteroids and other immunomodulatory agents, ultraviolet radiation and vitamin D analogues, are of unproven efficacy. Clinical trials evaluating combination therapy such as corticosteroids with MTX or UVA1 exposure with psoralens have not been established as consistently effective. New immunomodulators such as tacrolimus and thalidomide are also being evaluated. A better understanding of the molecular and cellular mechanisms of LS has led to evaluation of new treatments that modulate profibrotic cytokines such as TGF-beta and IL-4, regulate assembly and deposition of extracellular matrix components, and restore Th1/Th2 immune balance by administering IL-12 or IFN-gamma. IFN-gamma acts by directly inhibiting collagen synthesis and by restoring immune balance. In this review, we evaluate current and future treatment options for LS and cutaneous involvement in SSc. Recent advances in therapy focus mainly on anti-fibrotic agents. Delivery of these drugs into the skin as the target tissue might be a key factor in developing more effective and safer therapy.

    Joint replacement infections and osteomyelitis are among the most serious complications in orthopaedics and traumatology. The risk factors for these infections are often bacterial resistance to antimicrobials. One of the few solutions available to control bacterial resistance involves antimicrobials, which have a different mechanism of action from traditional antibiotics. Antimicrobial peptides (AMP) appear to be highly promising candidates in the treatment of resistant infections. We have identified several AMP in the venom of various wild bees and designed analogues that show potent antimicrobial activity and low toxicity against eukaryotic cells. The aim of the present study was to test the efficacy of one of those synthetic peptide analogues for the treatment of acute osteomyelitis invoked in laboratory rats. Femoral cavities of 20 laboratory Wistar rats were infected with Staphylococcus aureus. After 1 week, eight rats received an injectable calcium phosphate carrier alone, another eight rats were treated with a calcium phosphate mixed with AMP, and four rats were left without any further treatment. After another week, all rats were euthanized and radiographs were made of both the operated and healthy limbs. The animals with the carrier alone exhibited more severe acute osteomyelitis on radiographs in comparison to the recipients of the calcium phosphate carrier loaded AMP and untreated infected individuals. Based on the results of the above mentioned experiment, it was concluded that when injected directly into the site of femoral acute osteomyelitis, the calcium phosphate carrier mixed with AMP reduced osteomyelitis signs visible on radiographs.

    To investigate the efficacy and safety of low-concentration 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in the treatment of different severity of acne vulgaris and optimize the treatment regimen. A self-controlled multicenter clinical trial was carried out in 15 centers throughout China. A total of 397 acne patients of grade II-IV received 3- or 4-session PDT treatment. 5% ALA gel was applied topically to acne lesions for 1h incubation. The lesions were irradiated by a LED light of 633 nm at dose levels of 96-120 J/cm(2). Clinical assessment was conducted before and after every treatment up to 8 weeks. The effective rate overall and of grade II, III and IV are 82.1%, 71.6%, 79.6% and 88.2%, respectively. The effective rate rises significantly proportionally to the severity of acne (P0.05). The count of inflammatory and non-inflammatory acne lesions gradually decrease after each treatment (Pacne vulgaris in Chinese patients. Superior efficacy is found in severe cystic acne of grade IV with mild side effects. Copyright © 2013 Elsevier B.V. All rights reserved.

    Port wine stain (PWS) birthmarks are a congenital cutaneous vascular malformation involving ecstatic post-capillary venules. Current standard treatment for PWS is the pulsed dye laser (PDL). Vascular-targeted photodynamic therapy (PDT) has been used for the treatment of PWS in China since the early 1990's. Both can achieve a certain degree of color blanching in various types of PWS lesions. However, the majority of PWS lesions require multiple treatments. Some PWS lesions can recur or become darker after successful treatment. Recently, it has been proposed that this phenomenon might be initiated by neoangiogenesis that can be caused by treatment via wound healing response. The combined use of photothermolysis and a topical application of an angiogenic inhibitor such as Imiquimod and Rapamycin, were evaluated in several pilot studies. It is well-known that PDT can induce various host immune responses VEGF overexpression. Recent clinical data also show that improved clinical outcomes are obtained through the combination of ocular PDT and anti-VEGF therapy. This article will discuss rationales and implications of using such a combination modality and highlight recent progress based on our clinical experience and published data.

    The aim of the present study was to develop liposomal gel containing ketoconazole and neem extract for the treatment of seborrheic dermatitis in an effectual means. Azoles derivatives that are commonly used to prevent superficial fungal infections include triazole category like itraconazole. These drugs are available in the form of oral dosage that required a long period of time for treatment. Ketoconazole is available in the form of gel but is not used with any herbal extract. Neem ( Azadirachta indica) leaves show a good anti-bacterial and anti-fungal activity and have great potential as a bioactive compound. The thin film hydration method was used to design an herbal liposomal preparation. The formulation was further subjected to their characterization as particle size, zeta potential, entrapment efficiency, % cumulative drug release, and anti-fungal activity and it was also characterized by the mean of their physicochemical properties such as FTIR, SEM, DSC, TGA, and AFM. The results show that the formulation of liposomes with neem extract F12 were found to be optimum on the basis of entrapment efficiency in the range 88.9 ± 0.7%, with a desired mean particle size distribution of 141.6 nm and zeta potential - 45 mV. The anti-fungal activity of liposomal formulation F12 was carried out against Aspergillus niger and Candida tropicalis by measuring the inhibition zone 8.9 and 10.2 mm, respectively. Stability of optimized formulation was best seen at refrigerated condition. Overall, these results indicated that developed liposomal gel of ketoconazole with neem extract could have great potential for seborrheic dermatitis and showed synergetic effect for the treatment.

    Targeting the TNFα pathway is a validated approach to the treatment of psoriasis. In this pathway, TACE stands out as a druggable target and has been the focus of in-house research programs. In this article, we present the discovery of clinical candidate 26a. Starting from hits plagued with poor solubility or genotoxicity, 26a was identified through thorough multiparameter optimisation. Showing robust in vivo activity in an oxazolone-mediated inflammation model, the compound was selected for development. Following a polymorph screen, the hydrochloride salt was selected and the synthesis was efficiently developed to yield the API in 47% overall yield. Copyright © 2017. Published by Elsevier Ltd.

    Herpes simplex virus (HSV) is a common human pathogen. Despite current antivirals, it causes a significant medical burden. Drug resistant strains exist and they are especially prevalent in immunocompromised patients and in HSV eye infections. New treatment modalities are needed. BALB/c mice were corneally infected with HSV and subsequently treated with a swarm of enzymatically created, Dicer-substrate small interfering RNA (siRNA) molecules that targeted the HSV gene UL29. Two infection models were used, one in which the infection was predominantly peripheral and another in which it spread to the central nervous system. Mouse survival, as well as viral spread, load, latency and peripheral shedding, was studied. The anti-HSV-UL29 siRNA swarm alleviated HSV infection symptoms, inhibited viral shedding and replication and had a favourable effect on mouse survival. Treatment with anti-HSV-UL29 siRNA swarm reduced symptoms and viral spread in HSV infection of mice and also inhibited local viral replication in mouse corneas.

    Acne vulgaris is a common dermatologic disease in African patients, as well as in Caucasians. Our report evaluates the safety and efficacy of adapalene gel 0.1% in African patients with acne vulgaris. We used a 12-week, 2-center, open-label, noncomparative study of adapalene gel 0.1% in 65 African patients with acne vulgaris to assess the drug's effect on hyperpigmented lesions in people with dark skin. The study demonstrated that the progressive and significant improvements in lesion counts and global acne grades produced by adapalene in African patients were paralleled by significant improvements in the degree of hyperpigmentation of acne lesions. During treatment with adapalene, less than 5% of patients reported moderate or severe skin irritation at any time during the study, and the incidence of skin oiliness decreased markedly. We conclude that adapalene gel 0.1% was well tolerated and highly effective in African patients with acne vulgaris and was found to reduce hyperpigmentation.

  17. Macroevolutionary dynamics and historical biogeography of primate diversification inferred from a species supermatrix.

    Directory of Open Access Journals (Sweden)

    Mark S Springer

    Full Text Available Phylogenetic relationships, divergence times, and patterns of biogeographic descent among primate species are both complex and contentious. Here, we generate a robust molecular phylogeny for 70 primate genera and 367 primate species based on a concatenation of 69 nuclear gene segments and ten mitochondrial gene sequences, most of which were extracted from GenBank. Relaxed clock analyses of divergence times with 14 fossil-calibrated nodes suggest that living Primates last shared a common ancestor 71-63 Ma, and that divergences within both Strepsirrhini and Haplorhini are entirely post-Cretaceous. These results are consistent with the hypothesis that the Cretaceous-Paleogene mass extinction of non-avian dinosaurs played an important role in the diversification of placental mammals. Previous queries into primate historical biogeography have suggested Africa, Asia, Europe, or North America as the ancestral area of crown primates, but were based on methods that were coopted from phylogeny reconstruction. By contrast, we analyzed our molecular phylogeny with two methods that were developed explicitly for ancestral area reconstruction, and find support for the hypothesis that the most recent common ancestor of living Primates resided in Asia. Analyses of primate macroevolutionary dynamics provide support for a diversification rate increase in the late Miocene, possibly in response to elevated global mean temperatures, and are consistent with the fossil record. By contrast, diversification analyses failed to detect evidence for rate-shift changes near the Eocene-Oligocene boundary even though the fossil record provides clear evidence for a major turnover event ("Grande Coupure" at this time. Our results highlight the power and limitations of inferring diversification dynamics from molecular phylogenies, as well as the sensitivity of diversification analyses to different species concepts.

    With possible implications in multiple autoimmune diseases, the retinoic acid receptor-related orphan receptor RORγ has become a sought-after target in the pharmaceutical industry. Herein are described the efforts to identify a potent RORγ inverse agonist compatible with topical application for the treatment of skin diseases. These efforts culminated in the discovery of N-(2,4-dimethylphenyl)-N-isobutyl-2-oxo-1-[(tetrahydro-2H-pyran-4-yl)methyl]-2,3-dihydro-1H-benzo[d]imidazole-5-sulfonamide (CD12681), a potent inverse agonist with in vivo activity in an IL-23-induced mouse skin inflammation model. © 2018 Wiley-VCH Verlag GmbH & Co.

    Two percent topical minoxidil is the only US Food and Drug Administration-approved drug for the treatment of female androgenetic alopecia (AGA). Its success has been limited by the low percentage of responders. Meta-analysis of several studies reporting the number of responders to 2% minoxidil monotherapy indicates moderate hair regrowth in only 13-20% of female patients. Five percent minoxidil solution, when used off-label, may increase the percentage of responders to as much as 40%. As such, a biomarker for predicting treatment response would have significant clinical utility. In a previous study, Goren et al. reported an association between sulfotransferase activity in plucked hair follicles and minoxidil response in a mixed cohort of male and female patients. The aim of this study was to replicate these findings in a well-defined cohort of female patients with AGA treated with 5% minoxidil daily for a period of 6 months. Consistent with the prior study, we found that sulfotransferase activity in plucked hair follicles predicts treatment response with 93% sensitivity and 83% specificity. Our study further supports the importance of minoxidil sulfation in eliciting a therapeutic response and provides further insight into novel targets for increasing minoxidil efficacy. © 2014 Wiley Periodicals, Inc.

    Conclusion: Finding an effective and safe treatment regimen for AA, especially in children is difficult. Our regimen allows for more rapid lowering of oral doses with maintaining the cosmetic response and minimizing the side effects. Therefore, a trial course of this regiment would seem to be a reasonable approach for nearly hopeless but highly motivated pediatric patients of extensive and recalcitrant AA.

    2016-01-01

    Conclusion: Indications for surgical treatment of NHNA can be: unsatisfying response to topical agents; young patients who want to restore the aesthetic appearance of the breast; and patients with concomitant indication for corrective surgery of the breast. Advantages are: predictable time of healing; predictable final result; radical excision of the affected tissue; and possibility of histologic analysis of the whole areola. In rare cases of lesions extending to the breast, preliminary treatment with topical agents can limit the extent of excision. Management and treatment should always be tailor-made for each individual case.

    A single application of a water-miscible cream base containing the recently identified mitosis inhibitory epidermal pentapeptide pyroGlu-Glu-Asp-Ser-GlyOH (EPP) to hairless mouse skin is followed by a long-lasting period of reduced epidermal cell proliferation. To examine if a similar growth inhibition could be achieved in stimulated and rapidly proliferating epidermis, EPP was applied at two different concentrations, 0.005 or 0.02%, to hairless mouse skin immediately after exposure of the left flank to an erythemic dose of ultraviolet B light (UVB). This dose of UVB alone induces a sustained period of rapid epidermal cell proliferation, starting at about 18 h after the irradiation. Epidermal cell proliferation was followed from 18 to 54 h (0.005% cream) or from 18 to 30 h (0.02% cream) after the treatment by estimating the rate of G2-M cell flux (the mitotic rate) by means of Colcemid, and epidermal DNA synthesis by counting labeled cells after pulse-labeling with 3H-thymidine. The unirradiated side of the mice was used as reference. The results showed that topical treatment with a 0.02% EPP cream partially inhibited UVB-induced epidermal hyperproliferation, while the 0.005% EPP cream inhibited as well as stimulated the UVB-induced hyperproliferation. Thus, EPP is effective even in rapidly proliferating epidermal cell populations, but the outcome is obviously dose-dependent in this test system

    Full Text Available Background: Onychomycosis is a fungal infection of nails caused by dermatophytes, yeasts and molds. Aims: To study the efficacy and safety of oral terbinafine pulse as a monotherapy and in combination with topical ciclopirox olamine 8% or topical amorolfine hydrochloride 5% in onychomycosis. Methods: A clinical comparative study was undertaken on 96 Patients of onychomycosis during the period between August 2005 to July 2006. Forty-eight patients were randomly assigned in group A to receive oral terbinafine 250 mg, one tablet twice daily for seven days every month (pulse therapy; 24 patients in group B to receive oral terbinafine pulse therapy plus topical ciclopirox olamine 8% to be applied once daily at night on all affected nails; and 24 patients in group C to receive oral terbinafine pulse therapy plus topical amorolfine hydrochloride 5% to be applied once weekly at night on all the affected nails. The treatment was continued for four months. The patients were evaluated at four weekly intervals till sixteen weeks and then at 24 and 36 weeks. Results: We observed clinical cure in 71.73, 82.60 and 73.91% patients in groups A, B and C, respectively; Mycological cure rates against dematophytes were 88.9, 88.9 and 85.7 in groups A, B and C, respectively. The yeast mycological cure rates were 66.7, 100 and 50 in groups A, B and C, respectively. In the case of nondermatophytes, the overall response was poor: one out of two cases (50% responded in group A, while one case each in group B and group C did not respond at all. Conclusion: Terbinafine pulse therapy is effective and safe alternative in treatment of onychomycosis due to dermatophytes; and combination therapy with topical ciclopirox or amorolfine do not show any significant difference in efficacy in comparison to monotherapy with oral terbinafine.

    Minoxidil is efficacious in inducing hair growth in patients with androgenetic alopecia by inducing hair follicles to undergo transition from the early to late anagen phase. Although the efficacy of 1% topical minoxidil has been confirmed in Japan, no controlled study of 5% topical minoxidil has been conducted using male Japanese subjects. The objective of this trial was to verify the superiority in clinical efficacy of 5% topical minoxidil to 1% topical minoxidil in a double-blind controlled study with male, Japanese androgenetic alopecia patients as the subjects. The trial included 300 Japanese male patients aged 20 years or older with androgenetic alopecia who were administered either 5% topical minoxidil (n = 150) or 1% topical minoxidil (n = 150) for 24 weeks. The mean change from the baseline in non-vellus hair/cm(2), the primary efficacy variable, was 26.4 (n = 142) in the 5% topical minoxidil group and 21.2 (n = 144) in the 1% topical minoxidil group at 16 weeks, the main time point for the evaluation. The difference between the groups was significant (P = 0.020). The incidence of adverse events was 8.7% (13/150) in the 5% group and 5.3% (8/150) in the 1% group, with no significant difference between the groups (chi(2)-test: P = 0.258). Our findings confirmed the superiority of 5% topical minoxidil to 1% topical minoxidil in treating Japanese men with androgenetic alopecia.

    The objective of the study was to evaluate the effect of ligation of the ipsilateral common carotid artery (CCA) combined with various antimycotic treatments for the prevention of epistaxis in horses with guttural pouch mycosis. For each case, ipsilateral ligation of the CCA was performed, followed by application of various topical medications under endoscopic guidance. Frequency and number of treatments, outcome and recurrence of haemorrhage were retrospectively recorded. Twenty-four horses were included. Topical medication was administered by detachment of the diphtheric membrane and spraying (n=16) or by intralesional injection directly in the plaques using a transendoscopic needle (n=8). Epistaxis recurred in five horses (20.8 per cent), causing death of four horses (16.6 per cent). The mean number of treatments was 6.3±4.0 (range 2-14) for all topical treatments. Ligation of the ipsilateral CCA and topical medication carries a fair prognosis for avoidance of recurrent episodes of epistaxis, but fatal haemorrhage can occur. Removal of the fungal plaque and topical treatment of the underlying lesion appeared to speed up resolution of the mycotic mucosal lesions. The described technique is a salvage procedure when financial or technical constraints prevent the use of transarterial catheter occlusion techniques. British Veterinary Association.

    Topical application of timolol cream is effective and convenient for treating superficial infantile hemangiomas. Intralesional injection of corticosteroids, such as diprospan, is useful for the treatment of superficia infantile hemangiomas without systemic side effects. We conducted a self-controlled study to investigate whether a combination of intralesional injection of diprospan with topical timolol 0.5% cream would be more efficient than timolol cream alone in thick superficial infantile hemangiomas. Thirty-eight patients with 39 thick superficial infantile hemangiomas were recruited. Each lesion was randomly divided into two equal parts: one part was treated with topical timolol 0.5% cream (timolol cream group), while the other part was treated with injection of diprospan combined with topical timolol 0.5% cream (combined treatment group). Infants were followed every 4 weeks to determine whether injections should be continued, and timolol cream was applied four times daily for 5 months. During 5 months of treatment, three specialist physicians were invited to evaluate the therapeutic effects. The combined treatment group showed better lesion involution than did the timolol cream group regarding lesion thickness and color of lesions. The combination of intralesional injection of diprospan with topical timolol 0.5% cream is a suitable and safe strategy for thick superficial infantile hemangiomas. © 2018 Wiley Periodicals, Inc.

    Histological examination is the gold standard for actinic keratosis diagnosis; however, it is not always a feasible approach. Reflectance confocal microscopy (RCM) is a non-invasive technique that may be an alternative for monitoring actinic keratoses treatment response. Topical 5-fluorouracil is indicated for actinic keratosis multiple lesions and for field cancerization treatment. To assess the RCM accuracy, sensibility and specificity for actinic keratosis, considering as a gold standard the histopathological examination; as well as to evaluate the efficacy of 5% 5-fluorouracil treatment. This is a prospective study in actinic keratosis patients between August 2014 and November 2015. RCM analyses were performed in one randomly selected actinic keratosis lesion of the upper limbs by two independent observers before and after 5% 5-fluorouracil treatment. At the end of treatment and with clinical bleaching of treated lesions, histological examination was performed by two pathologists. A total of 50 lesions were enroled, and 40 lesions presented complete clinical bleaching after treatment and were included in the final analysis.

Samples were characterized using polarized light microscopy (PLM and rheology analysis. In vitro safety profile was evaluated using red cell hemolysis and in vitro cytotoxicity assays. In vitro antioxidant activity was performed by the DPPH method. PLM analysis showed the presence of lamellar LCS just to TLS. Regardless of the presence of RP, the rheological studies showed the pseudoplastic behavior of the formulations. The results showed that the incorporation of RP in LCS improved the safety profile of the drug. In vitro antioxidant activity suggests that LCS presented a higher capacity to maintain the antioxidant activity of RP. PFS-based systems may be a promising platform for RP topical application for the treatment of skin aging.

    Finasteride at 1 mg/day and 5% topical minoxidil are effective in male androgenetic alopecia (MAGA). However, studies describing their effects in Chinese individuals are scarce. 450 Chinese MAGA patients were randomly assigned to receive finasteride (n = 160), minoxidil (n = 130) and combined medication (n = 160) for 12 months. The patients returned to the clinic every 3 months for efficacy evaluation. And efficacy was evaluated in 428 men at treatment end, including 154, 122, and 152 in the finasteride, 5% minoxidil, and combination groups, respectively. All groups showed similar baseline characteristics, including age at enrollment, and duration and severity of alopecia (p > 0.05). At 12 months, 80.5, 59, and 94.1% men treated with finasteride, 5% minoxidil and the combination therapy showed improvement, respectively. Adverse reactions were rare (finasteride, 1.8%; minoxidil, 6.1%), and disappeared right after drug withdrawal. In conclusion, finasteride is superior to 5% minoxidil, while the combined medication showed the best efficacy. © 2015 Wiley Periodicals, Inc.

    Compare the safety and efficacy of topical gentian violet with that of nystatin oral suspension (NYS) for the treatment of oropharyngeal candidiasis in HIV-1-infected adults in resource-limited settings. Multicenter, open-label, evaluator-blinded, randomized clinical trial at eight international sites, within the AIDS Clinical Trials Group. Adult HIV-infected participants with oropharyngeal candidiasis, stratified by CD4 cell counts and antiretroviral therapy status at study entry, were randomized to receive either gentian violet (0.00165%, BID) or NYS (500 000 units, QID) for 14 days. Cure or improvement after 14 days of treatment. Signs and symptoms of oropharyngeal candidiasis were evaluated in an evaluator-blinded manner. The study was closed early per Data Safety Monitoring Board after enrolling 221 participants (target = 494). Among the 182 participants eligible for efficacy analysis, 63 (68.5%) in the gentian violet arm had cure or improvement of oropharyngeal candidiasis versus 61 (67.8%) in the NYS arm, resulting in a nonsizable difference of 0.007 (95% confidence interval: -0.129, 0.143). There was no sizable difference in cure rates between the two arms (-0.0007; 95% confidence interval: -0.146, 0.131). No gentian violet-related adverse events were noted. No sizable differences were identified in tolerance, adherence, quality of life, or acceptability of study drugs. In gentian violet arm, 61 and 39% of participants reported 'no' and 'mild-to-moderate' staining, respectively. Cost for medication procurement was significantly lower for gentian violet versus NYS (median $2.51 and 19.42, respectively, P = 0.01). Efficacy of gentian violet was not statistically different than NYS, was well tolerated, and its procurement cost was substantially less than NYS.

    To investigate the safety and preliminary efficacy of OT-551, a disubstituted hydroxylamine with antioxidant properties, for the treatment of geographic atrophy (GA), the advanced atrophic form of age-related macular degeneration (AMD). The study was a single-center, open-label phase II trial, enrolling 10 participants with bilateral GA. Topical 0.45% OT-551 was administered in one randomly assigned eye three times daily for 2 years. Safety measures were assessed by complete ophthalmic examination, fundus photography, and review of symptoms. The primary efficacy outcome measure was the change in best corrected visual acuity at 24 months. Secondary efficacy measures included changes in area of GA, contrast sensitivity, microperimetry measurements, and total drusen area from baseline. Study drug was well tolerated and was associated with few adverse events. The mean change in BCVA at 2 years was +0.2 ± 13.3 letters in the study eyes and -11.3 ± 7.6 letters in fellow eyes (P = 0.0259). However, no statistically significant differences were found between the study and fellow eyes for all other secondary outcome measures. OT-551 was well tolerated by study participants and was not associated with any serious adverse effects. Efficacy measurements in this small study indicate a possible effect in maintaining visual acuity. However, the absence of significant effects on other outcomes measures in this study suggests that OT-551, in the current concentration and mode of delivery, may have limited or no benefit as a treatment for GA (ClinicalTrials.gov number, NCT00306488).

    To investigate the topical effect of dorzolamide versus ketorolac on retinitis pigmentosa (RP) and Usher's syndrome (US) macular edema. Prospective, randomized and interventional study. A total of 28 eyes of 18 patients were included. Five eyes had US, 23 had RP. Fifteen eyes were allocated to ketorolac tromethamine 0.5% (4 drops daily regimen) and 13 eyes to dorzolamide hydrochloride 2% (3 drops daily regimen) treatment groups. Snellen's best-corrected visual acuity (BCVA), foveal thickness (FT) and foveal zone thickness (FZT) measured by Stratus® optical coherence tomography (OCT) were evaluated at baseline, 1, 3, 6 and 12 months after treatment. Patients assigned to ketorolac had a baseline BCVA of 0.37 ± 0.17 logMAR which improved at the end of 1 year to 0.28 ± 0.16 (p = 0.02). Three eyes (20%) of 2 patients improved by 7 letters or more. Mean FT and FZT did not change significantly during the study follow-up. After 1 year of treatment, 4 eyes (27%) of 3 patients showed an improvement of at least 16% of FT and 11% of FZT. Patients assigned to dorzolamide had a baseline BCVA of 0.48 ± 0.34 logMAR which improved in the first 6 months (0.40 ± 0.30; p = 0.01), with a decrease at 1 year (0.42 ± 0.27; p = 0.20). Seven eyes (54%) of 5 patients had an improvement of 7 letters or more. Mean FT and FZT did not change significantly either. After 1 year of treatment, 3 eyes (23%) of 2 patients showed an improvement of at least 16% on FT and 11% on FZT. RESULTS suggest that dorzolamide and ketorolac might improve visual acuity and therefore be of interest in selected cases. No relationship between retinal thickness fluctuation and visual acuity was found. Sample size was a limitation to the study. © 2014 S. Karger AG, Basel.

    Full Text Available Objective: To determine the efficacy of topical curcumin in reducing breast inflammation in women suffering from lactational mastitis. Methods: A randomized double-blind, placebo-controlled study including 63 breastfeeding women with lactational mastitis were randomly assigned to receive curcumin topical cream, one pump every 8 hours for 3 days (n=32 or topical moisturizer as placebo (n=31. Using an index for severity of breast inflammation, all of the patients had moderate breast inflammation before entering the study. The outcome of treatment was evaluated using the same index at 24, 48 and 72 hours of starting the treatment. Results: There was no significant difference between two study groups regarding the baseline characteristics such as age (p=0.361 and duration of lactation (p=0.551. After 72-hour of therapy, patients in curcumin groups had significantly lower rate of moderate (p=0.019 and mild (p=0.002 mastitis. Patients in curcumin group had significantly lower scores for tension (p<0.001, erythema (p<0.001 and pain (p<0.001, after 72-hour of treatment. Conclusion: The results of the current study indicate that topical preparation of curcumin successfully decrease the markers of lactational mastitis such as pain, breast tension and erythema within 72 hours of administration without side effects. Thus, topical preparation of curcumin could be safely administered for those suffering from lactational mastitis after excluding infectious etiologies.

    To compare the efficacy of dioctahedral smectite and iodine glycerin (DSIG) cream with topical mouth rinse (composed of saline, gentamicin and Vitamin B12) in treatment of chemotherapy induced oral mucositis (OM). A total of 130 intensive chemotherapy or stem cells transplantation induced OM patients were recruited. Among these patients, 67 patients received topical mouth rinse and 63 patients received DSIG cream treatment. The OM would be treated on the OM appearance and sustained for 5 days. OM severity was measured daily using The American Oncology Nursing Society recommended Oral Assessment Guideline (OAG) score system. Compared with topical mouth rinse treatment, a significant lower OAG score was observed in DSIG cream treated patients. Specifically, the OAG scores were respectively 12.1 ± 1.1, 12.0 ± 1.2, 11.3 ± 1.3 and 10.4 ± 1.3 from day 2 to day 5 in topical mouth rinse treatment subgroup. Correspondingly, the OAG scores were respectively 10.2 ± 1.0, 9.3 ± 0.9, 8.5 ± 0.6 and 8.0 ± 0.2 for DSIG cream treatment subset (all P < 0.05). Importantly, compared with topical mouth rinse treatment, the DSIG cream significantly shortened OM repair time (4.68 ± 0.98 vs. 8.76 ± 1.80 days, P < 0.001). After 5 days treatment, 54 patients (85.7%) obtained complete regression with an OAG score ≤8, and 7 patients (11.1%) had partial regression with an OAG score of 9-10 in DSIG cream treatment subgroup. However, only 2 patients (3.0%) obtained completed regression and 32 patients (47.8%) had partial regression in topical mouth rinse treatment cohort. Moreover, no serious side-effect was observed in both cohorts. Compared with topical mouth rinse, DSIG cream significantly lowered the OAG score and shortened OM duration.

Inhibition of tyrosinase, a key regulator of melanin production, has been used as an effective strategy to treat hyperpigmentation. In this study, we investigated the use of solid lipid nanoparticles (SLNs as a highly effective and nontoxic means to deliver a newly synthesized potent tyrosinase inhibitor, MHY498, and to target melanocytes through the skin. MHY498-loaded SLNs (MHY-SLNs were prepared by an oil-in-water emulsion solvent-evaporation method, and their morphological and physicochemical properties were characterized. MHY-SLNs showed a prolonged drug-release profile and higher skin permeation than that of MHY solution. In an in vivo evaluation of antimelanogenic activity, MHY-SLNs showed a prominent inhibitory effect against ultraviolet B-induced melanogenesis, resulting in no change in the skin color of C57BL/6 mouse, compared with that observed in an MHY solution-treated group and an untreated control group. The antimelanogenic effect of MHY-SLNs was further confirmed through Fontana–Masson staining. Importantly, MHY-SLNs did not induce any toxic effects in the L929 cell line. Overall, these data indicate that MHY-SLNs show promise in the topical treatment of hyperpigmentation. Keywords: melanogenesis, hyperpigmentation, MHY498, solid lipid nanoparticles, skin delivery

    Key features of lip aging include loss of volume, color, and definition as well as increases in lines/wrinkles and uneven skin texture. A single-center, open-label clinical study was conducted to assess the efficacy and tolerability of a novel, topical two-step lip treatment (HA5 LS) in female subjects presenting with mild to moderate lip dryness and mild to severe lip condition. Subjects were instructed to apply HA5 LS at least three times a day to ensure coverage 8 hours a day for four weeks. Clinical assessments for efficacy and tolerability were conducted at baseline, baseline post-application, week 2, and week 4. Standardized digital photography, subject self-assessment questionnaires, and instrumentation measurements for skin hydration (corneometer) and lip plumpness (digital caliper) were also conducted. Thirty-six female subjects aged 22-40 years enrolled in the study. HA5 LS provided instant and long term effects, achieving significant improvements in all clinical grading parameters including lip texture, color, definition/contour, scaling, cupping, lines/wrinkles, lip plumpness, and overall lip condition from baseline post-application to week 4 (all P less than equal to .001; Wilcoxon signed-rank test). Instrumentation measurements for hydration and digital caliper at weeks 2 and 4 were also significant (all P less than equal to .032; paired t-test). HA5 LS was also well-tolerated and highly-rated by subjects throughout the study duration. Results from this study suggest that HA5 LS addresses the key features of lip aging, providing both instant and long-term benefits. J Drugs Dermatol. 2017;16(4):366-371..

    The objective of this study is to compare the effects of topical estrogen and genistein (a soy isoflavone) on the facial skin collagen of postmenopausal women not undergoing systemic hormonal therapy. This is a prospective, double blind, randomized, controlled clinical trial. Volunteer women (N = 30) 45-55 year old from the Endocrine Gynecology sector of the Gynecology Department of the Federal University of São Paulo (UNIFESP). The Ethical Committee of the Federal University of São Paulo approved the study (report no. 386/2004; registration on ClinicalTrials.gov NCT01553773), were assigned to topical treatment with either estrogen or genistein for 24 weeks. We quantified and compared facial collagen concentration before and after each treatment by performing pre-auricular skin biopsies. Our data showed an increase in the amount of both type I and type III facial collagen by the end of both treatments. However, the outcomes of the estrogen GI (ER) group were superior to the genistein GII (GEN) group, with statistical significance p < 000.1 Conclusion: Treatment with topical estrogen is superior to genistein, but both have positive impacts on facial skin collagen. Nevertheless, it is still unclear whether prolonged use of genistein and other topical phytoestrogens could produce systemic effects and further research is needed to clarify this question.

    Psoriasis is a common, chronic, inflammatory, multi-system disease with predominantly skin and joint manifestations affecting approximately 2% of the Population. In this third of 6 sections of the guidelines of care for psoriasis, we discuss the use of topical medications for the treatment of psoriasis. The majority of patients with psoriasis have limited disease (<5% body surface area involvement) and can be treated with topical agents, which generally provide a high efficacy-to-safety ratio. Topical agents may also be used adjunctively for patients with more extensive psoriasis undergoing therapy with either ultraviolet light, systemic or biologic medications. However, the use of topical agents as monotherapy in the setting of extensive disease or in the setting of limited, but recalcitrant, disease is not routinely recommended. Treatment should be tailored to meet individual patients' needs. We will discuss the efficacy and safety of as well as offer recommendations for the use of topical corticosteroids, vitamin D analogues, tazarotene, tacrolimus, pimecrolimus, emollients, salicylic acid, anthralin, coal tar, as well as combination therapy.

    Mice with a constitutive or tamoxifen-induced Cre recombinase (Cre) expression are frequently used research tools to allow the conditional deletion of target genes via the Cre-loxP system. Here we analyzed for the first time in a comprehensive and comparative way, whether retinal Cre expression or topical tamoxifen treatment itself would cause structural or functional changes, including changes in the expression profiles of molecular markers, glial reactivity and photoreceptor vulnerability. To this end, we characterized the transgenic α-Cre, Lmop-Cre and the tamoxifen-inducible CAGG-CreER™ mouse lines, all having robust Cre expression in the neuronal retina. In addition, we characterized the effects of topical tamoxifen treatment itself in wildtype mice. We performed morphometric analyses, immunohistochemical staining, in vivo ERG and angiography analyses and realtime RT-PCR analyses. Furthermore, the influence of Cre recombinase or topical tamoxifen exposure on neuronal vulnerability was studied by using light damage as a model for photoreceptor degeneration. Taken together, neither the expression of Cre, nor topical tamoxifen treatment caused detectable changes in retinal structure and function, the expression profiles of investigated molecular markers, glial reactivity and photoreceptor vulnerability. We conclude that the Cre-loxP system and its induction through tamoxifen is a safe and reliable method to delete desired target genes in the neural retina. Copyright © 2016 IBRO.

    Aloe vera gel is widely used in the treatment of an array of disturbances, especially skin disorders. The wound-healing effects have been attributed to its moisturizing and anti-inflammatory effects as well as its beneficial effect on the maturation of collagen. The aim of the present study is to compare the effects of topically applied extracts of Aloe ferox with that of Aloe vera on the symptoms as well as IgE levels of a mouse model of atopic dermatitis (AD). Mice were sensitized and challenged with 2,4-dinitrochlorobenzene and treated afterwards for 10 consecutive days with the gels of either A. ferox or A. vera applied topically to the affected areas. A placebo gel was used for the control mice. Blood was collected at the beginning and end of the treatment period to measure serum IgE levels. Although the gels of both the Aloe species inhibited the cutaneous inflammatory response as well as serum IgE levels in the rats, the extracts of A. ferox were superior to that of A. vera in reducing IgE levels. The gels of A. ferox and A. vera, applied topically, may be a safe and useful alternative to antihistamines and topical corticosteroids, for the treatment of patients suffering from recurring chronic AD.

    Molluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution. The study design is a double-blind, randomized clinical trial, using three types of topical treatment. The treatment consist of daily applications of potassium hydroxide (KOH) in aqueous solution at 10% and 15% concentration, and a placebo administered in the control group. Four follow-up visits (at 15, 30, 45 and 60 days) are planned to evaluate treatment effectiveness and patient tolerance. The main outcome measure of the trial will be the healing rate, defined as lesion disappearance in the affected zones after the topic application of the experimental treatment. Secondary measures will be the principal characteristics and evolution of the affected zone (surface area, number of lesions, size and density of lesions), treatment tolerance (hyperpigmentation, itching, burning, pain), recurrence rate and the natural evolution of lesions in the control group. KOH can potentially be an effective and safe treatment for MC in primary care, and can also reduce referrals to dermatologists and hospital pediatric departments. In addition, KOH may be a valid and less expensive alternative to current invasive treatments (surgical excision).

The main outcome measure of the trial will be the healing rate, defined as lesion disappearance in the affected zones after the topic application of the experimental treatment. Secondary measures will be the principal characteristics and evolution of the affected zone (surface area, number of lesions, size and density of lesions, treatment tolerance (hyperpigmentation, itching, burning, pain, recurrence rate and the natural evolution of lesions in the control group. Discussion KOH can potentially be an effective and safe treatment for MC in primary care, and can also reduce referrals to dermatologists and hospital pediatric departments. In addition, KOH may be a valid and less expensive alternative to current invasive treatments (surgical excision. Trial Registration ClinicalTrials.gov: NCT01348386

    To examine the clinical response to topical administration of clotrimazole in dogs with nasal aspergillosis, to compare effect of surgically placed versus nonsurgically placed catheters used for administration on outcome, and to examine whether subjective scoring of computed tomographic images can predict outcome. Retrospective case series. 60 dogs with nasal aspergillosis. Information including signalment, history, diagnostics, treatment method, and outcome was retrieved from medical records of dogs with nasal aspergillosis treated between 1990 and 1996 at the University of California School of Veterinary Medicine or cooperating referral practices. Final outcome was determined by telephone conversations with owners and referring veterinarians. Images obtained before treatment were subjectively assessed to develop an algorithm for predicting outcome. Clotrimazole solution (1%) was infused during a 1-hour period via catheters surgically placed in the frontal sinus and nose (27 dogs) and via nonsurgically placed catheters in the nose (18). An additional 15 dogs received 2 to 4 infusions by either route. Topical administration of clotrimazole resulted in resolution of clinical disease in 65% of dogs after 1 treatment and 87% of dogs after one or more treatments. The scoring system correctly classified dogs with unfavorable and favorable responses 71 to 78% and 79 to 93% of the time, respectively. Topical administration of clotrimazole, using either technique, was an effective treatment for nasal aspergillosis in dogs. Use of non-invasive intranasal infusion of clotrimazole eliminated the need for surgical trephination of frontal sinuses in many dogs and was associated with fewer complications

    Full Text Available Because of the ever-increasing incidence of ultraviolet light B (UVB-induced skin cancer, considerable attention is being paid to prevention through the use of both sunscreens and after sun treatments, many of which contain antioxidants. Vitamin E is included as an antioxidant in many sunscreens and lotions currently on the market. Studies examining the efficacy of vitamin E as a topical preventative agent for UVB-induced skin cancer have yielded conflicting results. A likely contributor to differences in study outcome is the stability of vitamin E in the particular formulation being tested. In the current study we examined the effects of topical vitamin E alone as well as vitamin E combined with vitamin C and ferulic acid in a more stable topical formula (C E Ferulic®. Mice were exposed to UVB for 10 weeks in order to induce skin damage. Then, before the appearance of any cutaneous lesions, mice were treated for 15 weeks with a topical antioxidant, without any further UVB exposure. We found that topical C E Ferulic decreased tumor number and tumor burden and prevented the development of malignant skin tumors in female mice with chronically UVB-damaged skin. In contrast, female mice chronically exposed to UVB and treated topically with vitamin E alone showed a trend towards increased tumor growth rate and exhibited increased levels of overall DNA damage, cutaneous proliferation, and angiogenesis compared to vehicle-treated mice. Thus, we have demonstrated that topical 5% alpha tocopherol may actually promote carcinogenesis when applied on chronically UVB-damaged skin while treating with a more stable antioxidant compound may offer therapeutic benefits.

    Full Text Available Birt-Hogg-Dubé syndrome (BHD is a rare autosomal dominant disorder characterised by the occurrence of benign, mostly facial, skin tumours called fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax and an increased renal cancer risk. Current treatments for fibrofolliculomas have high rates of recurrence and carry a risk of complications. It would be desirable to have a treatment that could prevent fibrofolliculomas from growing. Animal models of BHD have previously shown deregulation of mammalian target of rapamycin (mTOR. Topical use of the mTOR inhibitor rapamycin is an effective treatment for the skin tumours (angiofibromas in tuberous sclerosis complex, which is also characterised by mTOR deregulation. In this study we aimed to determine if topical rapamycin is also an effective treatment for fibrofolliculomas in BHD.We performed a double blinded, randomised, facial left-right controlled trial of topical rapamycin 0.1% versus placebo in 19 BHD patients. Trial duration was 6 months. The primary outcome was cosmetic improvement as measured by doctors and patients. Changes in fibrofolliculoma number and size were also measured, as was occurrence of side effects.No change in cosmetic status of fibrofolliculomas was reported in the majority of cases for the rapamycin treated (79% by doctors, 53% by patients as well as the placebo treated facial sides (both 74%. No significant differences between rapamycin and placebo treated facial halves were observed (p = 1.000 for doctors opinion, p = 0.344 for patients opinion. No significant difference in fibrofolliculoma number or change in size of the fibrofolliculomas was seen after 6 months. Side effects occurred more often after rapamycin treatment (68% of patients than after placebo (58% of patients; p = 0.625. A burning sensation, erythema, itching and dryness were most frequently reported.This study provides no evidence that treatment of fibrofolliculomas with topical

    The nonablative, fractional, 1,927-nm diode laser is theoretically a safe and effective treatment for hyperpigmentation and melasma in darker skin and may potentiate topical cosmeceutical delivery. To evaluate the use of a nonablative, fractional, 1,927-nm diode laser with and without topical 2% hydroquinone (HQ) cream for moderate-to-severe facial hyperpigmentation in Fitzpatrick skin Types III-V. Forty adults underwent 4 laser treatments at 2-week intervals and were randomized to daily application of 2% HQ cream or moisturizer. Follow-ups were conducted 4 and 12 weeks after the final laser treatment. Hydroquinone and moisturizer groups demonstrated Mottled Pigmentation Area and Severity Index improvements of approximately 50% at post-treatment Weeks 4 and 12. Blinded investigator-assessed hyperpigmentation and photodamage improved significantly for both the groups at post-treatment Weeks 4 and 12. Subject satisfaction improved significantly in both the groups by post-treatment Week 4. Although investigator-rated Global Aesthetic Improvement Scale scores were significantly better in the HQ group at post-treatment Week 12, satisfaction was higher among those using moisturizer. No adverse events were noted. The nonablative, fractional, 1,927-nm diode laser produced significant improvement in hyperpigmentation in Fitzpatrick skin Types III-V by 4 weeks, with maintenance of results at 12 weeks after treatment even without HQ.

    Tracheobronchial stenosis is a known complication of endobronchial tuberculosis. Despite antituberculous and steroid therapy, the development of bronchial stenosis is usually irreversible and requires airway patency to be restored by either bronchoscopic or surgical interventions. We report the use of balloon dilatation and topical mitomycin-C to successful restore airway patency. We present a 24-year old lady with previous pulmonary tuberculosis and laryngeal tuberculosis in 2007 and 2013 respectively who presented with worsening dyspnoea and stridor. She had total left lung collapse with stenosis of both the upper trachea and left main bronchus. She underwent successful bronchoscopic balloon and manual rigid tube dilatation with topical mitomycin-C application over the stenotic tracheal segment. A second bronchoscopic intervention was performed after 20 weeks for the left main bronchus stenosis with serial balloon dilatation and topical mitomycin-C application. These interventions led to significant clinical and radiographic improvements. This case highlights that balloon dilatation and topical mitomycin-C application should be considered in selected patients with tracheobronchial stenosis following endobronchial tuberculosis, avoiding airway stenting and invasive surgical intervention.

    Background: Chronic recalcitrant plantar fasciitis is a disabling condition. We presumed if shock wave could increase the permeability of skin and facilitate penetration of topical corticosteroid through the skin; the combinational therapeutic effect would be stronger than using shock wave alone. The study purpose was to utilize the synergistic effect of shock wave and topical corticosteroid in treatment of plantar fasciitis. Materials and Methods: Patients in both groups (n = 40) received four sessions of shock wave with the same protocol at weekly intervals. At 30 min before each session, we used an occlusive dressing of topical clobetasol for the intervention group and Vaseline oil for the control group. Pain severity was assessed with visual analog scale (VAS) and modified Roles and Maudsley score (RMS) at baseline and 1 month and 3 months after intervention. Plantar fascia (PF) thickness was measured with ultrasonography at baseline and 3 months after intervention. Results: One month after intervention, VAS morning showed significant improvement in intervention group (P = 0.006) and RMS showed better improvement in intervention group (P = 0.026). There was no significant difference between the two groups after 3 months in RMS or VAS score. PF thickness was decreased significantly in both groups, but it was not significant between the two groups (P = 0.292). Conclusions: This combinational therapy yielded earlier pain reduction and functional improvement than using shock wave alone; topical corticosteroid could enhance the effectiveness of shockwave in short-term in the treatment of recalcitrant plantar fasciitis.

    Topical photochemotherapy with psoralen and its derivatives 4,5',8-trimethylpsoralen (TMP) and 8-methoxypsoralen (8-MOP), with UVA irradiation, was evaluated with regard to minimum phototoxic dose, concentration, timing of UVA irradiation and systemic and local side-effects, in healthy volunteers. Psoralen (0.005%) in aqueous gel was found to be superior to TMP and 8-MOP in aqueous gel. No hyperpigmentation was seen after topical PUVA treatment with psoralen in aqueous gel. Patients with plaque-type psoriasis (n=7), palmoplantar psoriasis (n=7) and hyperkeratotic eczema (n=2) were treated. Topical PUVA therapy was effective in most psoriasis patients, without the occurrence of local or systemic side-effects. Moreover, hyperkeratotic eczema patients who did not respond to conventional therapy showed partial remission. These results indicate that topical PUVA therapy with psoralen in aqueous gel is a useful therapeutic modality for treatment of psoriasis patients, and patients with recalcitrant dermatoses such as palmoplantar psoriasis and hyperkeratotic eczema.

    In an in vitro study, fixed-combination fortified vancomycin and amikacin ophthalmic solutions (VA solution) had the same potency and stable physical properties as the separate components. In this retrospective clinical study, we evaluated the efficacy of the topical VA solution in the treatment of bacterial corneal ulcer and comparison with separate topical fortified vancomycin and amikacin. Separate topical fortified eye drops was used prior to January 2004 and switched to the VA solution afterwards in the treatment of bacterial corneal ulcer. The medical records of 223 patients diagnosed with bacterial corneal ulcers between January 2002 and December 2005 were reviewed retrospectively. There were 122 patients in the VA group and 101 in the separate group. Cure was defined as complete healing of the ulcer accompanied by a nonprogressive stromal infiltrate on two consecutive visits. No significant difference was found between the VA and separate therapy group. The mean treatment duration was 15.4 days in the VA group and 16.1 days in the separate therapy group. The average hospital stay was 5.4 days (VA) and 7.2 days (separate antibiotics). Stromal infiltration regressed significantly without further expansion in both groups. All corneal ulcers completely re-epithelialized without complications related to drugs. VA solution provided similar efficacy to the conventional separate therapy in the treatment of bacterial corneal ulcers; however, it is more convenient and tolerable, promotes patient's compliance, avoids the washout effect, and reduces nurse utilization. Hence, VA solution is a good alternative to separate therapy.

    A combination topical suspension/gel containing calcipotriene plus betamethasone dipropionate has been developed as a safe and effective treatment for patients with psoriasis vulgaris of the scalp. This same preparation has the potential to be a convenient, effective, and cosmetically appealing formulation for psoriasis on the body. This trial evaluated the efficacy and safety of a topical suspension containing calcipotriene plus betamethasone dipropionate compared with its constituent components and topical suspension vehicle in the treatment of mild to moderate psoriasis on the trunk and limbs. This was a randomized, double-blind, vehicle-controlled, 4-arm trial in 1,152 subjects. The co-primary efficacy end points were the proportion of subjects achieving controlled disease based on the Investigators' Global Assessment of disease severity at weeks 4 and 8. Adverse events, vital signs, and clinical laboratory measurements were also assessed. At week 4, a greater proportion of subjects in the calcipotriene plus betamethasone group achieved controlled disease compared with subjects in the calcipotriene-only and vehicle-only treatment groups. At week 8, a statistically significantly (Psuspension containing calcipotriene plus betamethasone dipropionate traditionally used for scalp psoriasis is also a safe and effective once-daily treatment for psoriasis vulgaris on the body.

    Oral lichen planus (OLP) is a chronic inflammatory disease that causes bilateral white striations, papules, or plaques on the buccal mucosa, tongue, and gingivae. Erythema, erosions, and blisters may or may not be present. Several empirical therapies have been used in the treatment of (OLP). To evaluate the effect of low level laser therapy (LLLT) versus topical steroids for the treatment of erosive-atrophic lichen planus. Twenty-four patients with erosive-atrophic (OLP) were categorized into two groups. In the first group patients were treated with 970 nm diode laser irradiation, while, in the second group patients used topical corticosteroids (0.1% triamcinolone acetonide orabase). The gender, medical history and pain score were recorded. The pain score was measured before and after treatment by visual analogue scale (VAS). Steroid-treated group (0.1% triamcinolone acetonide orabase) show reduced pain score than laser group. Topical steroids are more effective than LLLT. LLLT may be used as an alternative treatment for symptomatic OLP when steroids are contraindicated.

    The efficacy of fluralaner, formulated as a chewable tablet (Bravecto™) or topical solution (Bravecto™ Spot-on Solution), was evaluated against naturally acquired Sarcoptes scabiei var. canis infestation in dogs. The study was performed in privately-owned dogs naturally infested with S. scabiei var. canis. All dogs living in the same household as the infested dog were enrolled into one of 3 groups (2 fluralaner treated and 1 negative control). All dogs within one household were administered the same treatment, with one dog per household included in further observations and assessments. In total, 29 dogs confirmed positive for sarcoptic mange were included. On Day 0, all dogs in group 1 (n = 9) were treated once orally with fluralaner at a minimum dose of 25 mg/kg body weight; all dogs in group 2 (n = 11) were treated once topically with fluralaner at a dose of 25 mg/kg body weight; and dogs in group 3 (n = 9) were treated once topically with saline solution. Sarcoptes scabiei var. canis mites on each dog were counted before treatment and at 4 weeks after treatment in deep skin scrapings (~4 cm(2)) from 5 different body areas. Clinical signs of infestation (i.e. erythematous papules; casts, scales and crusts; body areas with hair loss) and pruritus were recorded at the same time points. Single oral or topical treatment with fluralaner resulted in a 100 % reduction in mite counts post-treatment (group 1: P = 0.0009 and group 2: P = 0.0011). Resolution of clinical signs at four weeks post-treatment was variable, with improvement observed for erythematous papules, casts and crusts, and pruritus. All fluralaner treated dogs showed an improvement in overall hair re-growth compared with pre-treatment observations. Fluralaner administered either orally or topically to naturally infested dogs eliminates Sarcoptes scabiei var. canis mites and improves clinical signs over a 4-week observation period.

    Recurrent and painful ulcers of the oral mucosa and genital skin/mucosa are the most commonly observed manifestations in patients with Behçet's disease (BD). They affect patients' quality of life. Because of the effectiveness of granulocyte colony-stimulating factor (G-CSF) in wound healing, it may also be useful for the treatment of oral ulcers (OU) and genital ulcers (GU) of BD. We aimed to determine the efficacy of topically applied G-CSF in the treatment of OU and GU of BD. Seven patients with BD diagnosed according to the criteria of the International Study Group for Behçet's Disease were involved in the study. The patients were observed for 3 months before the study, and all occurrences were recorded during this period. Patients were given topical G-CSF for OU (4 x 120 microg/day, for 5 days) and/or GU (4 x 30 microg/day, for 5 days) and followed-up for 3 months after treatment. No concurrent disease-specific or immunosuppressive topical or systemic drugs were given during the study period. G-CSF treatment decreased the healing time and pain of OU and GU in six of seven patients compared with the pretreatment period. However, the effectiveness of the G-CSF treatment on OU and GU healing time and pain severity did not continue during the post-treatment period. G-CSF has beneficial effects on the healing duration and pain severity of OU and GU of patients with BD. However, given the high cost, impractical preparation and inability to cure the disease, G-CSF treatment should be chosen only in selected patients.

    Full Text Available Topical anesthetics are being widely used in numerous medical and surgical sub-specialties such as anesthesia, ophthalmology, otorhinolaryngology, dentistry, urology, and aesthetic surgery. They cause superficial loss of pain sensation after direct application. Their delivery and effectiveness can be enhanced by using free bases; by increasing the drug concentration, lowering the melting point; by using physical and chemical permeation enhancers and lipid delivery vesicles. Various topical anesthetic agents available for use are eutectic mixture of local anesthetics, ELA-max, lidocaine, epinephrine, tetracaine, bupivanor, 4% tetracaine, benzocaine, proparacaine, Betacaine-LA, topicaine, lidoderm, S-caine patch™ and local anesthetic peel. While using them, careful attention must be paid to their pharmacology, area and duration of application, age and weight of the patients and possible side-effects.

    Four laboratory studies were conducted to demonstrate that a single topical dose of a novel spot-on combination containing fipronil, amitraz and (S)-methoprene (CERTIFECT™, Merial Limited, GA, USA) is efficacious against the brown dog tick, Rhipicephalus sanguineus. In each study, 6-8 male and 6-8 female purpose-bred, laboratory mongrels, terrier cross or Beagles were randomly assigned to one of two study groups (treated and untreated), based on pre-treatment parasite counts. Starting on the day before treatment, each dog was infested weekly with 50 ticks. Ticks were thumb counted at various time points after treatment and weekly infestations starting as early as 6h and continued at 12, 18 and 24h depending on the study. Ticks were removed and counted at 48 h after treatment and weekly infestations. CERTIFECT provided rapid and excellent control of pre-existing and newly acquired infestations of R. sanguineus with efficacy as high as 93% within the first 12h after a single topical treatment. Excellent control (>96%) of R. sanguineus as early as 18 h, following post treatment infestations was maintained for at least 35 days. Copyright © 2011 Elsevier B.V. All rights reserved.

    2017-08-01

    Smoking is a risk factor in at least 18 cancers, and approximately two-thirds of cancer survivors continue smoking following diagnosis. Text mining of survivors' online posts related to smoking and quitting could inform strategies to reduce smoking in this vulnerable population. We identified posts containing smoking/cessation-related keywords from the Cancer Survivors Network (CSN), an online cancer survivor community of 166 000 members and over 468 000 posts since inception. Unsupervised topic model analysis of posts since 2000 using Latent Dirichlet Allocation extracted 70 latent topics which two subject experts inspected for themes based on representative terms. Posterior analysis assessed the distribution of topics within posts, and the range of themes discussed across posts. Less than 1% of posts (n = 3998) contained smoking/cessation-related terms, and covered topics related to cancer diagnoses, treatments, and coping. The most frequent smoking-related topics were quit smoking methods (5.4% of posts), and the environment for quitters (2.9% of posts), such as the stigma associated with being a smoker diagnosed with cancer and lack of empathy experienced compared to nonsmokers. Smoking as a risk factor for one's diagnosis was a primary topic in only 1.7% of smoking/cessation-related posts. The low frequency of smoking/cessation-related posts may be due to expected criticism/stigma for smoking but may also suggests a need for health care providers to address smoking and assist with quitting in the diagnostic and treatment process. Topic model analysis revealed potential barriers that should be addressed in devising clinical or population-level interventions for cancer survivors who smoke. Although smoking is a major risk factor for cancer, little is known about cancer patients' or survivors' views or concerns about smoking and quitting. This study used text mining of posts to an online community of cancer patients and survivors to investigate contexts in which

    Guidelines recommend limiting the duration of oral antibiotic therapy in acne to 3 to 6 months and prescribing concomitant topical retinoids for all patients. We sought to evaluate the duration of therapy with oral tetracyclines and the use of topical retinoids among patients with acne treated primarily by general practitioners in the United Kingdom. We conducted a retrospective cohort study using the Health Improvement Network database. The mean duration of therapy was 175.1 days. Of antibiotic courses, 62% were not associated with a topical retinoid; 29% exceeded 6 months in duration. If all regions were to achieve uses similar to the region with the shortest mean duration of therapy, approximately 3.3 million antibiotic days per year could be avoided in the United Kingdom. The Health Improvement Network does not include information on acne severity and clinical outcomes. Prescribing behavior for oral antibiotics in the treatment of acne among general practitioners is not aligned with current guideline recommendations. Increasing the use of topical retinoids and considering alternative agents to oral antibiotics when appropriate represent opportunities to reduce antibiotic exposure and associated complications such as antibiotic resistance and to improve outcomes in patients treated for acne.

    A simple efficacious topical treatment for cutaneous leishmaniasis (CL) is still an unresolved challenge. This study aimed to evaluate the efficacy of the topical use of thioxolone plus benzoxonium chloride (Thio-Ben) tincture in combination with cryotherapy in comparison with intralesional meglumine antimoniate (Glucantime) along with cryotherapy in treating anthroponotic CL (ACL). The study was conducted in Leishmaniasis Center in Dadbin Health Care Clinic, Kerman, Iran. Sixty-four CL lesions were randomly assigned to receive Thio-Ben plus cryotherapy (TC) (n = 32) or Glucantime plus cryotherapy (GC) (n = 32). Thio-Ben was used topically every other day and Glucantime was used intralesionally once a week for a maximum of 3 months. In both study groups, cryotherapy was administered using liquid nitrogen once every 2 weeks. Of 64 recruited lesions, 47 lesions completed the study protocol. Twenty lesions (91%) in TC group and 23 lesions (92%) in GC group showed complete cure. TC group showed faster clinical response. Pain, hypersensitivity reaction, dizziness, and nausea were only seen in GC group. This study showed that the topical use of Thio-Ben combined with cryotherapy has a good efficacy in treating ACL with the benefit that Thio-Ben has more patient compliance and less side effects than intralesional Glucantime. © 2015 Wiley Periodicals, Inc.

    Calcipotriol 50 µg/g and betamethasone 0.5 mg/g dipropionate (Cal/BD) aerosol foam formulation provides greater effectiveness and improved patient preference compared with traditional Cal/BD formulations for the topical treatment of plaque psoriasis. To determine the cost-effectiveness of Cal/BD foam compared with Cal/BD gel from the Australian perspective. A Markov model was developed to evaluate the cost-effectiveness of topical Cal/BD foam and gel for the treatment of people with plaque psoriasis. Treatment effectiveness, safety, and utilities were based on a randomized control trial, resource use was informed by expert opinion, and unit costs were obtained from public sources. Outcomes were reported in terms of 1-year costs, quality-adjusted life years, and incremental cost-effectiveness ratios. All costs were reported in 2017 Australian Dollars. The model showed that patients using Cal/BD foam had more QALYs and higher costs over 1 year compared with patients using Cal/BD gel, resulting in a cost of $13,609 per QALY gained at 4-weeks. When 4 weeks of Cal/BD foam was compared with 8 weeks of Cal/BD gel treatment, Cal/BD foam was $8 less expensive and resulted in 0.006 more QALYs gained. Sensitivity analyses showed that, compared with Cal/BD ointment, Cal/BD foam was associated with an incremental cost of $15,091 per QALY gained. Cal/BD foam is the most cost-effective Cal/BD formulation for the topical treatment of patients with plaque psoriasis.

    With shifts in island area, isolation, and cycles of island fusion-fission, the role of Quaternary sea-level oscillations as drivers of diversification is complex and not well understood. Here, we conduct parallel comparisons of population and species divergence between two island areas of equivalent size that have been affected differently by sea-level oscillations, with the aim to understand the micro- and macroevolutionary dynamics associated with sea-level change. Using genome-wide datasets for a clade of seven Amphiacusta ground cricket species endemic to the Puerto Rico Bank (PRB), we found consistently deeper interspecific divergences and higher population differentiation across the unfragmented Western PRB, in comparison to the currently fragmented Eastern PRB that has experienced extreme changes in island area and connectivity during the Quaternary. We evaluate alternative hypotheses related to the microevolutionary processes (population splitting, extinction, and merging) that regulate the frequency of completed speciation across the PRB. Our results suggest that under certain combinations of archipelago characteristics and taxon traits, the repeated changes in island area and connectivity may create an opposite effect to the hypothesized "species pump" action of oscillating sea levels. Our study highlights how a microevolutionary perspective can complement current macroecological work on the Quaternary dynamics of island biodiversity. © 2017 The Author(s).

    Competition among organisms has ecological and evolutionary consequences. However, whether the consequences of competition are manifested and measureable on macroevolutionary time scales is equivocal. Marine bivalves and brachiopods have overlapping niches such that competition for food and space may occur. Moreover, there is a long-standing debate over whether bivalves outcompeted brachiopods evolutionarily, because brachiopod diversity declined through time while bivalve diversity increased. To answer this question, we estimate the origination and extinction dynamics of fossil marine bivalve and brachiopod genera from the Ordovician through to the Recent while simultaneously accounting for incomplete sampling. Then, using stochastic differential equations, we assess statistical relationships among diversification and sampling dynamics of brachiopods and bivalves and five paleoenvironmental proxies. None of these potential environmental drivers had any detectable influence on brachiopod or bivalve diversification. In contrast, elevated bivalve extinction rates causally increased brachiopod origination rates, suggesting that bivalves have suppressed brachiopod evolution. © 2015 The Authors.

    Patients affected by cutaneous leishmaniasis need a topical treatment which cures lesions without leaving scars. Lesions are produced not only by the parasite but also by an uncontrolled and persistent inflammatory immune response. In this study, we proposed the loading of β-lapachone (β-LP) in lecithin-chitosan nanoparticles (NP) for targeting the drug to the dermis, where infected macrophages reside, and promote wound healing. Although the loading of β-LP in NP did not influence the drug antileishmanial activity it was critical to achieve important drug accumulation in the dermis and permeation through the skin. When topically applied in Leishmania major infected BALB/c mice, β-LP NP achieved no parasite reduction but they stopped the lesion progression. Immuno-histopathological assays in CL lesions and quantitative mRNA studies in draining lymph nodes confirmed that β-LP exhibited anti-inflammatory activity leading to the down-regulation of IL-1β and COX-2 expression and a decrease of neutrophils infiltrate. Cutaneous leishmaniasis often leaves patients with unsightly scars due to the body's inflammatory response to the infection. The authors in this paper described topical treatment using β-lapachone (β- LP) loaded in lecithin-chitosan nanoparticles (NP) in an animal model. Results confirmed the reduction of inflammatory response without affecting the parasite killing efficacy. These findings would pave way for further clinical testing in the near future.

    Several herbal remedies have been used as topical agents to cure burn wound, one of the most common injuries in worldwide. In this study, we investigated the potential use of Cleistocalyx operculatus essential oil to treat the burn wound. We identified a total of 13 bioactive compounds of essential oil, several of which exhibited the anti-inflammatory and antimicrobial activities. Furthermore, the essential oil showed the antibacterial effect against S. aureus but not with P. aeruginosa. The supportive effect of essential oil on burn wound healing process also has been proven. Among three groups of mice, wound contraction rate of essential oil treated group (100%) was significantly higher than tamanu oil treated (79%) and control mice (71%) after 20 days (0.22 ± 0.03 versus 0.31 ± 0.02 cm 2 , resp., p essential oil formed a complete epidermal structure, thick and neatly arranged fibers, and scattered immune cells in burn wound. On the contrary, saline treated burn wound formed uneven epidermal layer with necrotic ulcer, infiltration of immune cells, and existence of granulation tissue. This finding demonstrated Cleistocalyx operculatus essential oil as promising topical dermatological agent to treat burn wound.

    To assess the comparative effectiveness and cost-effectiveness (cost-utility) of a 0.05% emulsion of topical cyclosporine (Restasis; Allergan Inc, Irvine, California) for the treatment of moderate to severe dry eye syndrome that is unresponsive to conventional therapy. Data from 2 multicenter, randomized, clinical trials and Food and Drug Administration files for topical cyclosporine, 0.05%, emulsion were used in Center for Value-Based Medicine analyses. Analyses included value-based medicine as a comparative effectiveness analysis and average cost-utility analysis using societal and third-party insurer cost perspectives. Outcome measures of comparative effectiveness were quality-adjusted life-year (QALY) gain and percentage of improvement in quality of life, and for cost-effectiveness were cost-utility ratio (CUR) using dollars per QALY. Topical cyclosporine, 0.05%, confers a value gain (comparative effectiveness) of 0.0319 QALY per year compared with topical lubricant therapy, a 4.3% improvement in quality of life for the average patient with moderate to severe dry eye syndrome that is unresponsive to conventional lubricant therapy. The societal perspective incremental CUR for cyclosporine over vehicle therapy is $34,953 per QALY and the societal perspective average CUR is $11,199 per QALY. The third-party-insurer incremental CUR is $37,179 per QALY, while the third-party-insurer perspective average CUR is $34,343 per QALY. Topical cyclosporine emulsion, 0.05%, confers considerable patient value and is a cost-effective therapy for moderate to severe dry eye syndrome that is unresponsive to conventional therapy.

    Current treatments for erectile dysfunction (ED) have some limitations. This study evaluated the efficacy and tolerability of MED2005, a 0.2% glyceryl trinitrate topical gel, formulated into an enhanced absorption topical delivery system (DermaSys), administered on demand, in the treatment of ED. This randomized, double-blinded, placebo-controlled, phase II crossover trial involved 232 men with ED (231 treated, 230 assessed for efficacy) and their partners. After a 4-week run-in period, patients were randomized to 1 of 2 treatment sequences, MED2005-placebo or placebo-MED2005. Each treatment was given for 4 weeks, separated by a 1-week washout interval. Efficacy was assessed by the International Index of Erectile Function (IIEF), the Sexual Encounter Profile, a Global Assessment Questionnaire (GAQ), and specific questions about the onset and offset of action and treatment preferences (patients and partners). The primary outcome measure was the IIEF erectile function domain (IIEF-EF) score. Other efficacy assessments were secondary outcomes. The mean baseline IIEF-EF score was 17.1 (SD = 5.7), and this increased to 19.6 (SD = 7.5) after MED2005 treatment and 18.5 (SD = 6.7) after placebo (P = .0132). Overall, 23.1% of patients showed a clinically relevant (≥4-point) increase in IIEF-EF scores after treatment with MED2005 only compared with 14.5% who responded after MED2005 and placebo, 14.0% who responded after placebo only, and 48.4% who did not respond after either treatment (P = .0272). MED2005 also was associated with significant improvements compared with placebo in the other IIEF domains, and this was consistent with patients' and partners' responses to the GAQ. For all assessments, significant effects of MED2005 were seen primarily in patients with mild ED. The start of erection was noticed within 5 and 10 minutes in 44.2% and 69.5%, respectively, of all intercourse attempts with MED2005. Patients and partners showed significant preferences for MED2005

    Pimecrolimus and topical corticosteroids (TCS) combination therapy may provide an alternative treatment for patients with severe atopic dermatitis (AD), with faster clearance of disease flares, consequently reducing the duration of TCS treatment. To assess the safety profile of pimecrolimus cream 1% combined with fluticasone versus fluticasone alone in paediatric patients with severe AD. Patients (n = 376) were randomized to a combination of pimecrolimus cream 1% with fluticasone or vehicle plus fluticasone for 4 weeks. The primary outcome measure was the frequency of clinically relevant pre-defined adverse events (AEs) associated with the topical use of corticosteroids in patients with severe AD. Erythematous rash was the only AE, occurring more frequently in the combination group, while there were no noticeable differences in the frequency of other AEs of clinical interest between treatment groups. Efficacy variables were comparable between the two groups. A trend for greater time to relapse was observed for the combination of pimecrolimus cream 1% with fluticasone in patients who were clear at the end of treatment, with a marked improvement in facial AD. In paediatric patients with severe AD the overall safety profile of pimecrolimus cream 1% combined with fluticasone was similar to that of fluticasone alone.

    A clinical field investigation was conducted to evaluate the safety and efficacy of 10% imidacloprid/2.5% moxidectin for the treatment of ear mites (Otodectes cynotis) in dogs. The study was a multi-centered, blinded, positive controlled, randomized clinical trial conducted under field conditions with privately owned pets. A total of 17 veterinary clinics enrolled cases for the study. An otoscopic examination was performed to confirm the presence of O. cynotis residing in the ear of the dog prior to enrollment. A single-dog household was enrolled in the study if the dog had 5 or more ear mites and an acceptable physical examination. A multi-dog household was eligible if at least one dog in the household had 5 or more mites and all dogs in the household had acceptable physical exams and met the inclusion criteria. Qualified households were randomly assigned to treatments to receive either 10% imidacloprid+2.5% moxidectin topical solution or topical selamectin solution (positive control product) according to a pre-designated enrollment ratio of 2:1, respectively. If more than one dog in a multiple dog household had adequate numbers of ear mites, one dog was randomly selected to represent the household for efficacy evaluation prior to treatment. Treatments were administered twice per label and dose banding directions for each product approximately 28 days apart (Days 0 and 28), by the dog's owner at the study site. All dogs in a household were treated on the same day and with the same product. The owners completed a post-treatment observation form one day after each treatment. Post-treatment otoscopic examinations were performed by the investigators or attending veterinarian on Days 28 and 56. Physical examinations were performed on Days 0 and 56. One hundred and four (104) households were evaluated for efficacy on SD 28, and 102 households were evaluated for efficacy on SD 56. The dogs' ages ranged from 2 months to 16 years. A total of 247 dogs were evaluated for

    Patients with onychomycosis may mask infected nails with polish. Tavaborole topical solution, 5% is a boron-based, small-molecule pharmaceutical approved for the treatment of toenail onychomycosis caused by Trichophyton rubrum and Trichophyton mentagrophytes; efinaconazole topical solution, 10% is approved for the same indication. Nail polish appearance after application of tavaborole (dropper) or efinaconazole (brush); respective applicator appearance; presence of color transfer from respective applicators; and color transfer to remaining solutions after dosing of polished nails were evaluated. Twelve ex vivo human cadaver fingernails were cleaned, polished with two coats of L'Oréal® Nail Color, Devil Wears Red #420, and mounted on floral foam. Nails were treated with tavaborole or efinaconazole solutions once daily for 7 days. Dropper and brush applicators were applied to white watercolor paper immediately after dosing to evaluate color transfer from polished nails. On day 7, remaining solutions were transferred to clear glass vials to evaluate color transfer from applicators to solutions. Nails, applicators, and papers were photographed daily following application; remaining solutions were photographed after 7 days of dosing. Tavaborole-treated polished nails showed no polish discoloration, and tavaborole applicators did not change in appearance during treatment. No color transfer from polished nails was evident to applicator, paper, or remaining solution. Efinaconazole-treated polished nails showed substantial polish changes after the first day of treatment, with polish appearance and discoloration progressively worsening over 7 days of treatment. Color transfer from nails was evident to applicator, paper, and remaining solution. Daily dropper application of tavaborole to ex vivo polished nails did not alter polish appearance. Brush application of efinaconazole produced visible changes in polish appearance and color transfer to applicators, paper, and

    To evaluate the efficacy of topical administration of a 2% solution of cyclosporine (CsA) for treatment of dogs with keratoconjunctivitis sicca (KCS) and to correlate results with histopathologic characteristics and local cellular immunity of the gland of the third eyelid. 24 dogs with bilateral KCS. Lacrimal secretion was measured, using Schirmer tear test (STT) strips. Leukocyte and T-lymphocyte subsets were determined in blood samples. Histopathologic changes as well as CD4+, CD8+, and alpha-naphthyl-acetate esterase-positive (ANAE+) lymphocytes were evaluated. Clinical signs resolved at the end of 1 month in conjunction with significantly increased STT values, compared with baseline values. Fifteen and 30 days after discontinuation of CsA treatment, a decrease was observed in STT values in both eyes; however, only values for the right eye were significantly different. There was a significant decrease in the number of lymphocytes and ANAE+ lymphocytes 15 and 30 days after discontinuation of CsA treatment, compared with baseline values. Differences were not observed in number of CD4+ lymphocytes among treatment groups. However, there was a significant decrease in number of CD8+ lymphocytes with reversal of the CD4+:CD8+ in both eyes after CsA treatment for 30 days, compared with the control group. Increased secretory activity and decreased lymphocyte infiltration were characteristic histopathologic findings. Topical administration of a 2% solution of CsA was effective for the treatment of dogs with KCS. Strict follow-up monitoring is required after the cessation of treatment because of the possibility of recurrence of KCS.

    Oral lichen planus is an autoimmune disorder with several challenges in treatment. Photodynamic therapy has been proposed as a new treatment option for the disease. The present study compared the clinical effects of photodynamic therapy to dexamethasone mouthwash in the treatment of oral lichen planus lesions. In this randomized clinical trial, 30 patients with oral lichen planus were included.15 patients were treated with 5% methylene blue mediated photodynamic therapy using Fotosan device for 30s (630nm wavelength and 7.2-14.4J/cm 2 dose) for 4 sessions in the days 1, 4, 7, 14. In another group, the treatment was done on 15 patients by 0.5mg tab dexamethasone solution in 5cc water, rinsed 4 times in a day within two weeks. The sign score, symptoms scores (pain), clinical severity and treatment efficacy were measured at the days 15, 30, 60, 90 after beginning of the treatment. The results were subjected to Mann-whitney U test in both groups. No significant difference existed between the two modalities regarding the treatment efficacy index, sign score, symptom score and clinical severity on the 15, 30, 60 and 90 post-treatment days. Decreases in patient's symptoms were statistically significant in both groups. Photodynamic therapy was as effective as the dexamethasone mouth wash in the treatment of oral lichen planus. It could be used as a safe modality in the treatment of oral lichen planus lesions without identified side effects. Copyright © 2017 Elsevier B.V. All rights reserved.

    The use of light-emitting diode light offers practical advantages in photodynamic therapy (PDT) with topical methyl-aminolevulinate (MAL) for management of actinic keratoses (AK). We sought to evaluate the efficacy of MAL PDT using red light-emitting diode light. We conducted a multicenter, double-blind, randomized study. A total of 49 patients with 363 AK lesions had 16.8% MAL cream applied under occlusion for 3 hours, and 47 patients with 360 AK lesions had vehicle cream similarly applied. The lesions were then illuminated (630 nm, light dose 37 J/cm2) with repeated treatment 1 week later. Complete lesion and patient (all lesions showing complete response) response rates were evaluated 3 months after last treatment. MAL PDT was superior (PAK. MAL PDT using red light-emitting diode light is an appropriate treatment alternative for multiple AK lesions.

    This study aimed to evaluate the chronic topical anti-inflammatory activity of the pharmaceutical formulation ProHLP containing the hexane fraction of Lacistema pubescens (HLP). It was also investigated the possible cutaneous and systemic adverse effects of HLP and ProHLP in mice when compared to dexamethasone. The chronic topical anti-inflammatory activity was determined by croton oil multiple application-induced mouse ear oedema model. Histopathological analyses of ear tissue samples sensitized with croton oil were performed. Cutaneous atrophy induced by HLP and topical glucocorticoid treatments and excision skin wounds model to evidenced possible adverse reactions were also determined. ProHLP significantly reduced the mice ear oedema and considerably accelerated the wound-healing process. Also, HLP did not lead cutaneous atrophy and preserved the clinical aspect of the thymus, adrenal and spleen, unlike dexamethasone. The results suggested that ProHLP is an efficient and safer pharmaceutical formulation to treat chronic inflammatory diseases. © 2018 Royal Pharmaceutical Society.

    Full Text Available Acyclovir is not a good candidate for passive permeation since its polarity and solubility limit is partitioning into the stratum corneum. This work aims to develop a new topical formulation for the acyclovir delivery. New chitosan nanospheres (NS were prepared by a modified nano-emulsion template method. Chitosan NS were characterized by Dynamic Light Scattering (DLS, Transmission Electron Microscopy (TEM, and an in vitro release study. The in vitro skin permeation experiment was carried out using Franz cells and was equipped with porcine skin. Biological studies were performed on the Vero cell line infected by HSV-1 and HSV-2 strains. The acyclovir loaded chitosan NS appeared with a spherical shape, a size of about 200 nm, and a negative zeta potential of about 40.0 mV. The loading capacity of the drug was about 8.5%. In vitro release demonstrated that the percentage of acyclovir delivered from the nanospheres was approximately 30% after six hours. The in vitro skin permeation studies confirmed an improved amount of permeated acyclovir. The acyclovir-NS complex displayed a higher antiviral activity than that of free acyclovir against both the HSV-1 and the HSV-2 strain. The acyclovir-loaded NS showed no anti-proliferative activity and no signs of cytotoxicity induced by NS was detected. Confocal laser scanning microscopy confirmed that the NS are taken up by the cells.

    The 2 most commonly used topical agents for partial thickness burns are silver sulfadiazine (SSD) and collagenase ointment (CO). Silver sulfadiazine holds antibacterial properties, and eschar separation occurs naturally. Collagenase ointment is an enzyme that cleaves denatured collagen facilitating separation but has no antibacterial properties. Currently, there are no prospective comparative data in children for these 2 agents. Therefore, we conducted a prospective randomized trial. After institutional review board approval, patients were randomized to daily debridement with SSD or CO. Primary outcome was the need for skin grafting. Patients were treated for 2 days with SSD with subsequent randomization. Polymyxin was mixed with CO for antibacterial coverage. Debridements were performed daily for 10 days or until the burn healed. Grafting was performed after 10 days if not healed. From January 2008 to January 2011, 100 patients were enrolled, with no differences in patient characteristics. There were no differences in clinical course, outcome, or need for skin grafting. Wound infections occurred in 7 patients treated with CO and 1 patient treated with SSD (P = .06). Collagenase ointment was more expensive than SSD (P burns results. Copyright © 2012 Elsevier Inc.

    Photodynamic therapy (PDT) with aminolevulinic acid (ALA) or methyl aminolevulinate (MAL) is an approved modality for the non-invasive treatment of actinic keratoses (AK) and basal cell carcinoma (BCC) offering excellent cosmetic outcome. However, pain during and after illumination is the most frequent and limiting side effect. The aim of this study was to precisely assess how reported pain during PDT is influenced by sex, age, treatment site, disease (AK/BCC) as well as the photosensitizer used. 467 lesions consisting of AK (primary treatments: n=158; follow-up: n=47) or BCC (primary treatments: n=138; follow-up: 124) were treated by ALA- or MAL-PDT using metal halide lamps (580-750 nm). Pain was assessed during illumination using a continuous visual analogue scale (VAS). Factors predictive for higher pain levels during PDT are treatment of the head, treating AK and using ALA. The observed results may improve patient management and predict which level of pain to expect, and what kind of pain relief to prepare.

    Actinic keratoses (AK) are carcinomas in situ and can progress to invasive squamous cell carcinomas. Treatment of actinic keratoses can be achieved by physical ablation, chemotherapeutic agents, immunomodulators or photodynamic therapy. We conducted a proof of concept study with 15 patients. Overall 66 actinic keratoses were treated with 5-FU (0.5%) and salicylic acid (10%) for 4 weeks (3 times per week). After 12 weeks complete response of 47 AK (77%), partial response of 13 AK (21%) and non-response of 1 AK (2%) were achieved. Treatment was well tolerated and efficient.

    Context Incontinence-associated dermatitis (IAD) is a type of moisture-associated dermatitis caused by repeated skin exposure to urine or stool. A product that could mitigate such symptoms would have a significant impact on cost of care and patients' quality of life. Objective This study compared the clinical efficacy of RD1433 and a comparator product (Vaseline®) in preventing and treating experimental IAD skin lesions. Materials and methods For the "prevention" part of the study, skin sites in eight human volunteers were treated daily for 5 d with either RD1433 or Vaseline® immediately prior to synthetic urine exposure. In the "treatment" part, exposure to synthetic urine was substituted for Vaseline® or RD1433 application on the first 2 d to promote the development of skin lesions prior to the application of the products from day three. Product efficacy was quantified by visual scoring and an array of biophysical instruments. Results Both RD1433 and Vaseline® significantly reduced lesion progression when applied as a prophylactic. When applied as a treatment (following establishment of skin lesions), RD1433 demonstrated a statistically significant improvement in several measures of skin function whereas there was no statistically significant improvement following treatment with Vaseline®. Conclusions The findings of this study suggest that RD1433 may be superior to Vaseline® in the prevention and treatment of experimental IAD lesions. Clearly, further work is required to establish the efficacy of RD1433 with patients in a clinical environment.

  16. Preventative topical diclofenac treatment differentially decreases tumor burden in male and female Skh-1 mice in a model of UVB-induced cutaneous squamous cell carcinoma

    Ultraviolet B (UVB) light is the major environmental carcinogen contributing to non-melanoma skin cancer (NMSC) development. There are over 3.5 million NMSC diagnoses in two million patients annually, with men having a 3-fold greater incidence of squamous cell carcinoma (SCC) compared with women. Chronic inflammation has been linked to tumorigenesis, with a key role for the cyclooxygenase-2 (COX-2) enzyme. Diclofenac, a COX-2 inhibitor and non-steroidal anti-inflammatory drug, currently is prescribed to patients as a short-term therapeutic agent to induce SCC precursor lesion regression. However, its efficacy as a preventative agent in patients without evidence of precursor lesions but with significant UVB-induced cutaneous damage has not been explored. We previously demonstrated in a murine model of UVB-induced skin carcinogenesis that when exposed to equivalent UVB doses, male mice had lower levels of inflammation but developed increased tumor multiplicity, burden and grade compared with female mice. Because of the discrepancy in the degree of inflammation between male and female skin, we sought to determine if topical treatment of previously damaged skin with an anti-inflammatory COX-2 inhibitor would decrease tumor burden and if it would be equally effective in the sexes. Our results demonstrated that despite observed sex differences in the inflammatory response, prolonged topical diclofenac treatment of chronically UVB-damaged skin effectively reduced tumor multiplicity in both sexes. Unexpectedly, tumor burden was significantly decreased only in male mice. Our data suggest a new therapeutic use for currently available topical diclofenac as a preventative intervention for patients predisposed to cutaneous SCC development before lesions appear.

    PURPOSE OF INVESTIGATIONS: The aim of this randomized controlled trial was to evaluate efficacy and tolerability of a new association of lipohydroperoxides and glycyrrhetic acid on topical treatment of bacterial and mycotic vulvovaginitis. One hundred consecutive patients with bacterial or mycotic vulvovaginitis were randomly assigned to a study group treated with vaginal lipohydroperoxides and a derivative of glycyrrhetic acid for three days (n = 50), and a control group using vaginal antibacterial metronidazole (500 mg) or antimycotic econazole (150 mg) for six days (n = 50). A clinical and microbiological response was achieved in 80.4% and 88.9% in investigational and control group, respectively (p > 0.05). Compared to traditional antimicrobial drugs, the effect appears to be faster and safer, even if not significantly. The 6-month recurrence rate was 7.7% and 5.6% in the investigational and control group, respectively. Topical medication based on lipohydroperoxides and glycyrrhetic acid showed a clinical and microbiological efficacy in the first-line treatment of bacterial and mycotic vulvovaginitis, comparable to conventional drugs.

    A cream formulation containing high concentrations (10%) of a standard mixture of solasodine glycosides (BEC) has been shown to be effective in the treatment of malignant and benign human skin tumours. We now report that a preparation (Curaderm) which contains very low concentrations of BEC (0.005%) is effective in the treatment of keratoses, basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) of the skin of humans. In an open study, clinical and histological observations indicated that all lesions (56 keratoses, 39 BCCs and 29 SCCs) treated with Curaderm had regressed. A placebo formulation had no effect on a smaller number of treated lesions. Curaderm had no adverse effect on the liver, kidneys or haematopoietic system.

    Mondor's disease of the breast is a rare, benign sclerosing superficial thrombophlebitis of the subcutaneous veins of the anterior or lateral chest wall, which is treated conservatively. We aim in this study to evaluate the outcome and effectiveness of our treatment protocol using oral diclofenac sodium and topical diclofenac sodium patch in 172 patients. A retrospective database analysis of 172 female patients between January 2001 and December 2010 was done. The treatment protocol consisted of group 1: treatment by oral diclofenac sodium 100 mg once daily for 3 weeks. Group 2: treatment by diclofenac sodium patches for 8 hours twice daily (morning and evening) for 1 week. The patients were instructed to document the time as soon as pain relief is achieved following the patch application and the intake of the oral dose. The incidence rate was 2.49%. Diclofenac sodium patch was statistically found to be significantly better in subsiding the inflammatory process of the veins, relieving the pain, and enhancing faster healing rate. We conclude that diclofenac sodium patch showed a promising role in the treatment of Mondor's disease of the breast by significantly decreasing the inflammatory process due to its transdermal migration action within a short period and the ability to reach a high local concentration. It achieved the best results for rapid relief of pain and disease regression compared to the oral capsules. Therefore, our protocol was changed to implement diclofenac sodium patch as the first choice in treating Mondor's disease of the breast. © 2017 Wiley Periodicals, Inc.

    The high rate of relapse of acne lesions following oral isotretinoin treatment is a common problem which remains unsolved. To avoid or minimize relapses, topical retinoids have been used for many years as maintenance treatment. However, adverse effects frequently occur. To determine the efficacy and safety of a new retinoid combination (Retinsphere technology) in maintaining post-treatment response to oral isotretinoin. Prospective, randomized, double-blind and vehicle-controlled study of 30 patients with acne previously treated with isotretinoin. Treatment with the retinoid combination was applied to one side of the face and vehicle was applied to the other, once daily, for 3 months. Standardized photographs were taken using RBX technology at baseline, 1.5 months and 3 months. The primary efficacy endpoint was the appearance of relapse on the treated side compared to the vehicle-treated side. Other endpoints included lesion count, investigator-reported improvement, patient-reported improvement, impact on quality-of-life, and side effects. Although the majority of patients did not reach the total target dose of oral isotretinoin, the relapse rate was significantly lower on the retinoid-treated side compared to the vehicle-treated side. Likewise, improved lesion count and excellent tolerance were observed. This new retinoid combination (Retinsphere technology) were effective and safe as maintenance therapy after post-treatment response to oral isotretinoin in patients with acne.

    The aim of this work was to investigate new pro-vitamins based on α-tocopherol (α-Toc) and fatty acids, and to compare their properties with those of α-tocopherol acetate (α-TAc). Skin levels of α-Toc-fatty acid ester conjugates, total α-Toc and endogenous α-Toc were measured in skin samples taken from separate groups of treated and untreated rats. Multiple and extensive treatment with α-Toc oleate and α-TAc was also carried out to assess the skin accumulation and safety of these esters. The in-vivo studies revealed that α-Toc-fatty acid conjugates penetrated into the skin quantitatively while being comparable with the permeation of α-TAc. Differences were found between the levels of total α-Toc and endogenous α-Toc after application of α-TAc, α-Toc oleate, α-Toc linoleate, α-Toc-α linolenate and α-Toc palmitate, indicating that α-Toc conjugates of these fatty acids, but not α-Toc γ-linolenate or α-Toc stearate, were hydrolysed to free α-Toc. In long-term and extensive treatment, α-TAc was found to be lethal to rats treated with 1.15 mg/kg of this agent, which had been spread over 16 cm(2) of skin. Similar treatment with α-Toc oleate did not produce any side effects. This study suggests that α-Toc conjugates with unsaturated fatty acids may be a good alternative as stable vitamin E derivatives, rather than the α-TAc ester. © 2013 The Authors.

    Full Text Available ANGIPARSTM is a new herbal extract which has been produced in oral, topical, and intravenous forms. The present article contains preliminary results of the study which was planned to evaluate the efficacy and safety of orally applied ANGIPARSTM and to compare it with the combination of oral and topical forms and also with conventional therapy in patients with diabetic ulcers of the lower extremities."nTwenty one patients with diabetic foot ulcers were divided into 3 groups. The first group received 100 mg of oral ANGIPARSTM twice a day for 6 weeks in addition to conventional therapies. In the second group, ANGIPARSTM gel 3% was added to the oral form of the same product besides the conventional therapies for the same period of time. Finally, in the third group which was considered as control, only conventional therapies were performed. The patients were followed for 6 weeks. Parameters such as granulation tissue formation, skin epithelization, and wound surface areas changes were analyzed to determine the effectiveness of the compound in wounds healing. Furthermore, drug safety was assessed by monitoring adverse events and by clinical and laboratory evaluations."nThe study data showed significant differences between the intervention and control groups with respect to efficacy and tolerability. In each intervention group, primary wound healings occurred following 2 weeks. Complete wound healing which was greater than 70% improvement in wounds surface areas was achieved in 83% and 100% of group 1 and group 2 participants, respectively after 6 weeks. On the other hand, at the same period of time, only 22.2% of patients in control group revealed complete healing. Therefore, ANGIPARSTM had significant positive effect in increasing the incidence of complete wound closure compared with control group (p = 0.042. However, our evaluations indicated that adding topical treatment with 3% gel once a day to the oral therapy with the same product did not make

    There is yet no consensus among prescribers whether minoxidil (MXD) formulations should be applied on wet/damp or dry scalp and no clear FDA guidelines on the matter. We hypothesized that the use of MXD on damp scalp may lead to higher drug penetration. First, because the drug diffusion and consequent deposition into the hair follicle may be favored when follicle cast is humid. Second, because humidity may also prevent drug crystallization and, therefore, maintain a higher thermodynamic activity for longer periods, which leads to increased penetration. Following in vitro experiments on rat and porcine skin we confirmed the hypothesis, which could markedly improve treatment effectiveness. © 2016 Wiley Periodicals, Inc.

    The report examines environmental issues related to hydrostatic testing of discharge waters generated from integrity testing of natural gas pipelines. Hydrostatic testing, and proper environmental management of the discharge waters, can be required by DOT regulations. However, disposal of water used to conduct a hydrostatic pipeline test is regulated on a state-by-state basis. State-specific requirements vary widely, ranging from an authorization letter to a complete NPDES permit. Monitoring may be required before and during discharge, include a variety of analyses, have varying protocols for obtaining samples, and may be required either to obtain data or to ascertain compliance with stipulated discharge limits. The composition of the discharge and state-specific discharge limitations dictate treatment needs on a case-by-case basis. The volume consists of the Executive Summary of a five-volume report series

    The aim was to compare the effects of topical cyclosporine A and artificial tears combination with artificial tears alone in patients with dysfunctional tear syndrome (DTS). Forty-two eyes of 42 patients with DTS were enrolled in the study. The inclusion criteria for the study were Schirmer I (without anesthesia) scores below 10 mm/5 min and tear film break-up time (BUT) below 10 sec. The patients were randomly divided into two groups. The study group (22 patients) underwent 0.05% cyclosporine A treatment twice a day and preservative-free artificial tears for four times a day for 4 months. The control group (20 patients) was administered only preservative-free artificial tears four times a day for 4 months. The BUT, Schirmer test scores, corneal fluorescein staining, conjunctival lissamine green staining, and goblet cell density derived by impression cytology were recorded before and after treatment in each group. In the study group, all parameters improved statistically significantly after treatment at the 4-month follow-up compared with the pretreatment values (Ptears treatment significantly increases goblet cell density, decreases the signs of DTS, and improves ocular surface health.

    Full Text Available Burns are serious traumas related to skin damage, causing extreme pain and possibly death. Natural drugs such as Aloe vera and vitamin E have been demonstrated to be beneficial in formulations for wound healing. The aim of this work is to develop and evaluate polymeric films containing Aloe vera and vitamin E to treat wounds caused by burns. Polymeric films containing different quantities of sodium alginate and polyvinyl alcohol (PVA were characterized for their mechanical properties and drug release. The polymeric films, which were produced, were thin, flexible, resistant, and suitable for application on damaged skin, such as in burn wounds. Around 30% of vitamin E acetate was released from the polymeric films within 12 hours. The in vivo experiments with tape stripping indicated an effective accumulation in the stratum corneum when compared to a commercial cream containing the same quantity of vitamin E acetate. Vitamin E acetate was found in higher quantities in the deep layers of the stratum corneum when the film formulation was applied. The results obtained show that the bioadhesive films containing vitamin E acetate and Aloe vera could be an innovative therapeutic system for the treatment of burns.

    The aim of the research was to study a new cidofovir/sucralfate drug product to be used as a spray for treating the mucosal and/or skin lesions. The product, i.e., a water suspension of sucralfate (15% w/w) and cidofovir (1% w/w), combines the potent antiviral activity of the acyclic nucleoside phosphonate cidofovir ((S)-1-[3-hydroxy-2-(phosphonomethoxy)propyl]cytosine) and the wound healing properties of sucralfate gel (sucrose octasulphate basic aluminum salt). The product was characterized in vitro with respect to compatibility between drug and carrier, spray particle size, spray deposition, drying kinetics, and drug content and release. An interaction between the two active substances was found. The interaction between sucralfate and cidofovir was counteracted by introducing sodium dihydrogen phosphate (16% w/w) in the preparation. The spray formulation containing cidofovir/sucralfate gel painted the skin and dried quickly to a scab, remaining firmly adhered to the lesions. The therapeutic paint was tested in vivo on lambs infected with orf virus by treating the animals with different cidofovir/sucralfate formulations (0.5% or 1% cidofovir + sucralfate 15% + NaH(2)PO(4) 16% w/w) and with sucralfate gel suspension alone as control. The treatment with formulations containing cidofovir and phosphate salt for four consecutive days resulted in a rapid resolution of the lesions, with scabs containing significantly lower amounts of viable virus when compared with untreated lesions and lesions treated with sucralfate suspension alone.

    Skin Aging manifests primarily with wrinkles, dyspigmentations, texture changes, and loss of elasticity. During the skin aging process, there is a loss of moisture and elasticity in skin resulting in loss of firmness finally leading to skin sagging. The key molecule involved in skin moisture is hyaluronic acid (HA), which has a significant water-binding capacity. HA levels in skin decline with age resulting in decrease in skin moisture, which may contribute to loss of firmness. Clinical trials have shown that topically applied ROL effectively reduces wrinkles and helps retain youthful appearance. In the current study, ROL was shown to induce HA production and stimulates the gene expression of all three forms of hyaluronic acid synthases (HAS) in normal human epidermal keratinocytes monolayer cultures. Moreover, in human skin equivalent tissues and in human skin explants, topical treatment of tissues with a stabilized-ROL formulation significantly induced the gene expression of HAS mRNA concomitant with an increased HA production. Finally, in a vehicle-controlled human clinical study, histochemical analysis confirmed increased HA accumulation in the epidermis in ROL-treated human skin as compared to vehicle. These results show that ROL increases skin expression of HA, a significant contributing factor responsible for wrinkle formation and skin moisture, which decrease during aging. Taken together with the activity to increase collagen, elastin, and cell proliferation, these studies establish that retinol provides multi-functional activity for photodamaged skin.

  10. What defines an adaptive radiation? Macroevolutionary diversification dynamics of an exceptionally species-rich continental lizard radiation.

    2015-08-07

    Adaptive radiation theory posits that ecological opportunity promotes rapid proliferation of phylogenetic and ecological diversity. Given that adaptive radiation proceeds via occupation of available niche space in newly accessed ecological zones, theory predicts that: (i) evolutionary diversification follows an 'early-burst' process, i.e., it accelerates early in the history of a clade (when available niche space facilitates speciation), and subsequently slows down as niche space becomes saturated by new species; and (ii) phylogenetic branching is accompanied by diversification of ecologically relevant phenotypic traits among newly evolving species. Here, we employ macroevolutionary phylogenetic model-selection analyses to address these two predictions about evolutionary diversification using one of the most exceptionally species-rich and ecologically diverse lineages of living vertebrates, the South American lizard genus Liolaemus. Our phylogenetic analyses lend support to a density-dependent lineage diversification model. However, the lineage through-time diversification curve does not provide strong support for an early burst. In contrast, the evolution of phenotypic (body size) relative disparity is high, significantly different from a Brownian model during approximately the last 5 million years of Liolaemus evolution. Model-fitting analyses also reject the 'early-burst' model of phenotypic evolution, and instead favour stabilizing selection (Ornstein-Uhlenbeck, with three peaks identified) as the best model for body size diversification. Finally, diversification rates tend to increase with smaller body size. Liolaemus have diversified under a density-dependent process with slightly pronounced apparent episodic pulses of lineage accumulation, which are compatible with the expected episodic ecological opportunity created by gradual uplifts of the Andes over the last ~25My. We argue that ecological opportunity can be strong and a crucial driver of adaptive

    Life diversifies via adaptive radiation when natural selection drives the evolution of ecologically distinct species mediated by their access to novel niche space, or via non-adaptive radiation when new species diversify while retaining ancestral niches. However, while cases of adaptive radiation are widely documented, examples of non-adaptively radiating lineages remain rarely observed. A prolific cold-climate lizard radiation from South America (Phymaturus), sister to a hyper-diverse adaptive radiation (Liolaemus), has extensively diversified phylogenetically and geographically, but with exceptionally minimal ecological and life-history diversification. This lineage, therefore, may offer unique opportunities to investigate the non-adaptive basis of diversification, and in combination with Liolaemus, to cover the whole spectrum of modes of diversification predicted by theory, from adaptive to non-adaptive. Using phylogenetic macroevolutionary modelling performed on a newly created 58-species molecular tree, we establish the tempo and mode of diversification in the Phymaturus radiation. Lineage accumulation in Phymaturus opposes a density-dependent (or 'niche-filling') process of diversification. Concurrently, we found that body size diversification is better described by an Ornstein-Uhlenbeck evolutionary model, suggesting stabilizing selection as the mechanism underlying niche conservatism (i.e., maintaining two fundamental size peaks), and which has predominantly evolved around two major adaptive peaks on a 'Simpsonian' adaptive landscape. Lineage diversification of the Phymaturus genus does not conform to an adaptive radiation, as it is characterised by a constant rate of species accumulation during the clade's history. Their strict habitat requirements (rocky outcrops), predominantly invariant herbivory, and especially the constant viviparous reproduction across species have likely limited their opportunities for adaptive diversifications throughout novel

Considering that alopecia affects so many people and that there is currently no scientifically proven treatment with few side effects, new drug-delivery systems able to improve alopecia therapy are urgently required. With this purpose in mind, the present study aimed to develop lipid nanoparticles (nanostructured lipid carriers with the ability to incorporate and deliver anti-alopecia active compounds (minoxidil and finasteride into the dermis and hair follicles. Lipid nanoparticles, prepared by ultrasonication method, showed mean particle sizes around 200 nm, which is sufficient for reaching the dermis and hair follicles, and zeta potential values around -30 mV, which indicates good physical stability. Over 28 days of storage, no significant variations in these parameters were observed, which indicates that all nanoformulations are stable in storage over that period. Cryo-scanning electron microscope measurements showed that all the lipid nanoparticles exhibited a spherical shape and a smooth surface regardless of their composition. Differential scanning calorimetry studies allowed the determination of phase transition temperatures and confirmed the recrystallization of the lipid nanoparticles (recrystallization index between 11% and 86%. A high loading efficiency was achieved for finasteride (between 70% and 90%, while less than 30% was

Lesions take between 6 and 18 months to resolve spontaneously and are a source of great embarrassment to both caretakers and children, often affecting attendance at school and limiting social activity. Treatment options to date have been poorly tolerated by children but recent studies have suggested that potassium hydroxide may be beneficial. This double-blind, randomized, placebo-controlled study compared 10% potassium hydroxide with placebo (normal saline). Twenty patients, aged 2 to 12 years, were recruited. Parents applied a solution twice daily to lesional skin until signs of inflammation appeared. Children were examined by the same observer on days 0, 15, 30, 60, and 90. Seventy percent of children receiving topical potassium hydroxide cleared, compared with 20% in the placebo group. Further dosing studies are required to identify whether weaker concentrations of potassium hydroxide are as efficacious, with less irritancy.

    Full Text Available Two new topical immunomodulators, pimecrolimus cream and tacrolimus ointment for atopic dermatitis (AD in pediatric patients, have provided alternatives to topical corticosteroids without the associated adverse events. Objective: To evaluate the efficacy and safety of tacrolimus ointment and pimecrolimus cream for the treatment of AD in pediatric patients. MEDLINE, Embase, the CNKI and Cochrane Library databases were searched up to December 2008. Additional data sources were manual searches of abstract proceedings and personal contact with investigators and pharmaceutical companies. Two investigators assessed the quality of trials with unified tables independently. Disagreements on validity assessment were resolved through discussion or consultation with the third author. Quality analysis of methodology was evaluated according to the Jadad scale, including randomization, blinding and patients’ discontinuation. Twenty trials involving 6288 infants and children with AD met the inclusion criteria. More patients using tacrolimus had a good response than those in control groups including vehicle, 1% hydrocortisone acetate and 1% pimecrolimus, the corresponding OR were (4.56; 95%CI: 2.80 to 7.44, (3.92; 95% CI: 2.96 to 5.20 and (1.58; 95% CI: 1.18 to 2.12. The effect difference between 0.03% tacrolimus and 0.1% tacrolimus ointments was not statistically significant (OR = 0.90; 95% CI: 0.55 to 1.48. The incidence of adverse events of tacrolimus ointment or pimecrolimus cream was similar to the vehicle. The major adverse events were burning and pruritus. Both tacrolimus ointment and pimecrolimus cream are safe and effective in the treatment of AD in pediatric patients. Tacrolimus ointments were superior to pimecrolimus cream.

    Full Text Available Background and Design: Acne vulgaris is a multifactorial chronic inflammatory disase of the pilosebaceous unit. Topical antibiotics and anti-inflammatory treatment are used for mild and moderate acne. Clindamycin is frequently used for acne treatment, altough nadifloxacin is a relatively new agent. There are few studies evaluating nadifloxacin efficacy. It's impact on quality of life has not been determined previously. In this study, it is aimed to compare the effect of these two agents, and to evaluate the effect of these treatments on quality of life. Materials and Methods: Eighty patients with mild-moderate acne vulgaris were divided in two groups of 40 people that had no difference in terms of age, gender and acne severity. The combination of topical clindamycin and 5% benzoyl peroxide gel twice a day was given to group 1 for 12 weeks. The combination of nadifloxacin cream and 5% benzoyl peroxide gel twice a day was given to group 2 for 12 weeks. The number of the inflammatory and non-inflammatory lesions were recorded at baseline and on weeks 2, 4, 8, 12 and side effects were recorded and evaluated. Global improvement was evaluated separately by patients and doctor after the treatment. Before and after the treatment, the quality of life of the patients were evaluated with Skindex-29. Results: Both treatment group regimens were significantly effective on inflammatory and non-inflammatory lesions and were well tolerated by patients in terms of side effects. It was also observed that there was statistically significant recovery after treatment in terms of clinical severity and quality of life. There was not any statistically significant difference between two treatment methods in terms of effectiveness, side effect and quality of life. Conclusion: Nadifloxacin and 5% benzoyl peroxide combination is effective in the treatment and improvement of quality of life in acne patients.

  17. Recent advances in topical anesthesia

    Science.gov (United States)

    2016-01-01

    Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

    Full Text Available Balanitis xerotica obliterans (BXO is a chronic inflammatory skin disorder, considered the male genital variant of lichen sclerosus. Anti-inflammatory drugs are commonly used in BXO. We evaluated the effects of an innovative formulation of ozonated olive oil with vitamin E acetate (OZOILE® on the inflammatory status and tissue remodeling in male children with BXO. The mRNA transcripts of proteins involved either in inflammation or in dynamics of tissue regeneration were analyzed by quantitative real-time PCR, in foreskins affected by BXO removed from patients untreated or treated with OZOILE® cream for 7 days before circumcision. We found a significant reduction in mRNA levels of IL-1β, TNF-α, INF–γ, transglutaminase 2 and NOS2 in foreskins treated with OZOILE® in comparison to untreated ones (p < 0.001. No significant differences were observed in NF-κB activation in the specimens obtained from treated and untreated patients. Hence, OZOILE® treatment up-regulated hypoxia-inducible factor (HIF-1alpha, vascular endothelial growth factor (VEGF and E-cadherin gene expression (p < 0.001. The treatment with OZOILE® showed effective results in children affected by BXO by reducing the inflammatory process and stimulating mechanisms for tissue regeneration of the foreskin. A randomized clinical trial on a large number of children affected by BXO might be useful to verify the efficacy of topical treatment with OZOILE®.

    Full Text Available Organ transplant recipient (OTR subjects are at high risk of skin cancer such as squamous cell carcinoma and basal cell carcinoma. Actinic keratosis (AK is considered the precursor of these non-melanoma skin cancers. Sun protection is mandatory in subjects with AK and this preventive strategy is very important in OTR. Treatment of the field of cancerization is also crucial to reduce the risk of recurrence of skin lesions in AK and non-melanoma skin cancer patients. Activation of cyclooxygenase 1 and 2 enzymes plays an important role in the pathogenesis of skin cancers. Topical application of cyclooxygenase inhibitors such as diclofenac and, more recently, piroxicam has shown to reduce AK lesions in immunocompetent subjects. A medical device containing piroxicam and SPF 50+ sunscreen filters (P+SS has been demonstrated to be effective in reducing AK lesions and improving the field of cancerization. We report the effect of P+SS, applied for 16 weeks, in a case series of 10 OTR subjects with multiple AK lesions. P+SS treatment was associated with a relevant AK lesion reduction (>75% in 7 patients (with a complete clearance in 3 subjects with an improvement in the field of cancerization. This medical device could be considered a promising long-term curative and preventive treatment in OTR patients at high risk of non-melanoma skin cancers.

    Actinic keratoses (AK) are premalignant lesions occurring mainly in sun-damaged skin. Current topical treatment options for AK and photo-damaged skin such as liquid nitrogen and electrosurgery are not suitable for field treatment. Otherwise, therapies suitable for field treatment bring along considerable patient discomfort. Non-ablative fractional resurfacing has emerged as a logical treatment option especially for field treatment of AK. To evaluate the clinical efficacy of fractional laser therapy for clearing AK and improving skin quality. To compare patient friendliness of the "fractional" therapy with those reported for other field treatment modalities. Ten patients with Fitzpatrick skin type I to III with multiple AK and extensive sun-damaged skin, received 5-10 sessions with a 4-week interval using a 1550 nm Erbium-Glass Fractionated laser (Sellas, Korea). Four weeks and 24 weeks after the last treatment the clinical results were evaluated by an independent physician. The mean degree of improvement, in terms of reduction in the number of AK and improvement of skin texture, was 54% on a 4 point PGA scale, and persisted for approximately 6 months. The biggest advantage of fractional laser treatment, besides the eradication of AK and a clear rejuvenation effect, is the absence of "downtime". Fractional non-ablative resurfacing induces significant reduction in the number of AK and improves the skin quality. Also all patients preferred fractional laser therapy above other AK treatment modalities.

    Warts are commonly acquired viral tumors, caused by Human apilloma Virus (HPV). This virus can infect and cause disease at any site in the stratified squamous epithelium either keratinizing or non-keratinizing. A plantar wart (also called verruca plantaris) is a lesion that appears on the plantar surface of foot as a small, shining, sago-grain papule which soon assumes the typical appearance of a sharply-defined rounded lesion with a rough keratotic surface, surrounded by a smooth collar of thickened horn. Objective: To compare the efficacy and safety of oral zinc sulphate versus topical application of salicylic (16.7%) and lactic acid (16.7%) combination, in the treatment of plantar warts. Study Design: Comparative interventional study. Setting and Duration of Study: Department of Dermatology Unit-I, King Edward Medical University, Mayo Hospital Lahore, from 15 February, 2009 till 14 February, 2010. Methodology: After informed consent, one hundred patients of plantar warts were selected from the outpatient Department of Dermatology, Mayo Hospital, Lahore. The patients were divided into two equal groups; in group A, 50 patients were given oral zinc sulphate (10 mg/kg/day) in two or three divided doses and in group B, 50 patients were advised to apply a combination of salicylic (16.7%) and lactic acid (16.7%) once at night daily. In group A, using oral zinc sulphate, the treatment was given for two months and follow up continued for next 4 months. In group B, the topical preparation was also continued for 2 months or till the complete removal of wart (if before two months) and follow up was extended up to 4 months after treatment. Results:The mean age of patients in group A was 26.2 +- 8.1 years and in group B 26.3 +- 7.3 years. The mean number of warts in group A was 7.9 +- 3.5 and in group B 5.7 +- 2.6. The mean duration of disease in group A was 6.9 +- 4.1 months and in group B 6.0 +- 3.9 months. On follow up at 2nd month, in group A, 41 (82%) patients showed an

    Public health nurses report on effects of fresh human milk as treatment for conjunctivitis, rhinitis and atopic eczema (AE), the latter being highly prevalent in early childhood. Emollients and topical corticosteroids are first line treatment of AE. As many caregivers have steroid phobia, alternative treatment options for mild AE are of interest. The aim of this small pilot study was to assess the potential effects and risks of applying fresh human milk locally on eczema spots in children with AE. This was a split body, controlled, randomized and physician blinded pilot study, of children with AE with two similar contralateral eczema spots having a mother breastfeeding the child or a sibling. Fresh expressed milk and emollient was applied on the intervention spot and emollient alone on the control area, three times a day for four weeks. The severity and area of the eczema spots was evaluated weekly, and samples from milk and the spots were analysed weekly with respect to bacterial colonisation. Of nine patients included, six completed the study. Mean age at inclusion was 18.5 months. The spots examined were localized on the arms, legs or cheeks. The spots were similar in severity, but differed in area. In one patient the eczema ceased after inclusion. In four patients both control and intervention areas increased during the intervention. The relative change in eczema area compared to baseline showed less increase in the intervention spots in two patients, whereas the opposite was observed in three. In four children Staphylococcus aureus was found in their eczema once or more. In three of the 28 human milk samples, Staphylococcus aureus, alfa haemolytic streptococci or coagulase negative staphylococci were detected. Staphylococcus aureus was found once both in human milk and in the eczema spots, no clinical signs of infection were however observed. No secondary infection due to milk application was detected. In this small pilot study, no effect was found on eczema

    Tavaborole is a topical antifungal agent approved by the US Food and Drug Administration for the treatment of toenail onychomycosis. As part of the nonclinical development program, reproductive and developmental toxicity studies were conducted (rat oral fertility and early embryonic development, rat (oral) and rabbit (dermal) embryo-fetal development). There were no effects on fertility or reproductive performance at doses up to 300 mg/kg/d (107 times the maximum recommended human dose [MRHD] based on mean area under the plasma concentration-time curve comparisons). In the rat embryo-fetal development toxicity studies, teratogenicity was not observed at doses up to 100 mg/kg/d (29 times the MRHD). However, several treatment-related skeletal malformations and variations were observed at 300 mg/kg/d (570 times the MRHD). In rabbit embryo-fetal development toxicity studies dosed via oral or dermal administration, the no observable adverse effect level for maternal toxicity and embryo-fetal toxicity was 50 mg/kg/d (16 times the MRHD) and 5% (26 times the MRHD), respectively. © The Author(s) 2016.

    Atopic dermatitis (AD) is most prevalent in areas of reduced skin barrier reserve, like face and neck, especially in children. Treatment with topical corticosteroids (TCS) is limited due to heightened risk of treatment-associated side-effects, thus necessitating alternative AD therapies. The primary study objective was to determine the efficacy of pimecrolimus cream 1% in children with mild-moderate facial AD dependent on/intolerant of TCS. Secondary objectives included effects on overall Eczema Area and Severity Index (EASI), head/neck EASI, pruritus severity and time to clearance of facial AD. A multicentre, double-blind (DB) study of < or = 6 weeks, followed by a 6-week, open-label (OL) phase was conducted. Two hundred patients (aged 2-11 years) were randomized 1:1 to pimecrolimus cream 1% (n = 99) or vehicle (n = 101) twice daily until clearance of facial AD or for a maximum of 6 weeks (DB phase). Sixteen patients receiving vehicle were allowed to switch to the OL phase at day 22. Significantly more pimecrolimus-treated vs. vehicle-treated patients were cleared/almost cleared of facial AD (Investigators' Global Assessment 0/1): 74.5% vs. 51.0%, P < 0.001 (day 43) [57.1% vs. 36.0%, P = 0.004 (day 22)]. Median time to clearance was 22.0 vs. 43.0 days (pimecrolimus vs. vehicle, respectively). Statistically significant differences for pimecrolimus vs. vehicle were also seen on head/neck EASI, overall EASI, and head/neck pruritus scores. Adverse events were mainly mild-moderate, occurring with similar frequency in both treatment groups. In children with facial dermatitis intolerant of/dependent on TCS, pimecrolimus cream 1% effectively controls eczema and pruritus and is well tolerated.

The proportions of patients who achieved complete wound closure after 11, 20, and 30 weeks of treatment was 54%, 68%, and 78%, respectively; mean healing time was 15.5 ± 6.7 weeks. When individual weekly healing rates (the percentage reduction in wound area per week) were corrected for variability in initial DFU area, the values were nearly 6-fold higher for complete wound closure (7.8% ± 3.6%) than for incomplete wound closure (1.4% ± 0.7%) (Student t-test; P = 0.001). After 30 weeks of treatment, the number of colonized wounds decreased from 29 at baseline to 5, and the number of odorous wounds decreased from 19 to 1. Ulcer bed planimetry data showed a significant reduction in the amount of exudate, fibrin slough, and necrotic tissue after the treatment with C. officinalis hydroglycolic extract (χ(2) test; P = 0.001). No adverse events were observed during treatment. The study findings suggest C. officinalis extract is safe and has a beneficial effect on DFU healing. Randomized, controlled studies using C. officinalis hydroglycolic extract are warranted to confirm its safety and establish its clinical efficacy and effectiveness for the topical treatment of DFUs.

    A 55-year-old man with severe plaque psoriasis presented with a 2-week history of feeling generally unwell with lethargy and thirst. His symptoms had developed 6 weeks after commencement of the topical vitamin D3 analogue calcitriol. Investigations revealed hypercalcaemia and acute-on-chronic kidney injury, probably directly induced by systemic absorption of vitamin D3 following extensive topical use. Topical calcitriol had been started as a steroid-sparing agent to reduce the patient's liberal potent corticosteroid usage during anti-tumour necrosis factor-alfa therapy. Topical vitamin D analogues are commonly prescribed in dermatological and general practice, with hypercalcaemia being a rare but potentially serious adverse effect. This case serves to outline key factors that may predispose to hypercalcaemia, such as disease extent, quantity of drug applied, comorbidities and concurrent medications, and it highlights the importance of considering these factors when prescribing topical therapies. © 2016 British Association of Dermatologists.

  12. Topics in atomic physics

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen.

    The prevalence of dry eye following cataract surgery was reported as high as 55.7%, this acute and iatrogenic disorder urgently required appropriate clinical management. The purpose of this study is to compare the efficacy of diquafosol sodium ophthalmic solution (DQS) and conventional artificial tears (AT) for the treatment of dry eye following cataract surgery. The PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched from their earliest entries through June 2017 to obtain the studies, which evaluated the efficacy of DQS for patients with dry eye after cataract surgery. The relevant data were analyzed using StataSE 12.0 software. The PRISMA checklist was used as protocol of the meta-analysis and the guideline was followed. The weighted mean difference, relative risk, and their 95% confidence interval were used to assess the strength of the association. The authors identified 21 references of which 4 studies evaluating the efficacy of DQS for patients with dry eye after cataract surgery were included. The dataset consisted of 291 patients of dry eye following cataract surgery (371 postoperative eyes). The pooling result of our study suggested that the DQS could significantly better improve the indices like corneal and conjunctival fluorescein staining scores, tear breakup time, and Schirmer I test than AT (P dry eye. Based on the available evidence, topical DQS has a superior efficacy than AT in the management of dry eye after cataract surgery; however, further researches with larger sample sizes and focus on indicators such as higher-order aberrations, symptom questionnaire scores, and cost-effective ratio are required to reach a firmer conclusion.

    Colonization with Staphylococcus aureus in atopic dermatitis (AD) is often associated with worsening of clinical symptoms. Staphylococcus aureus produces superantigens that contribute to cutaneous inflammation and corticosteroid (CS) resistance. To investigate the relationship between CS insensitivity, S. aureus colonization and superantigen production in AD, and to explore the efficacy of pimecrolimus cream in CS-insensitive AD. This was a randomized, double-blind, vehicle-controlled, multicentre, parallel-group study. Seventy-three patients with AD, aged 2-49 years, who had a documented clinical insensitivity to topical CS, were recruited. The primary efficacy parameters combined laboratory (including S. aureus colonization, superantigens) and clinical assessments [including Eczema Area and Severity Index (EASI), whole body Investigator's Global Assessment (IGA), pruritus assessment score, patient's assessment score of disease control]. An increase in S. aureus counts correlated with worsening of clinical score (week 6 vs. baseline) when assessed by IGA, pruritus severity and patient assessment. The presence of superantigens correlated with this worsening. During the 6-week double-blind phase, disease improvement in the pimecrolimus cream group was demonstrated by decreasing EASI scores compared with vehicle. Mean EASI scores for the head and neck showed greater improvement in the pimecrolimus cream group than in the vehicle group at all observed time points. In a cohort of patients with clinical insensitivity to CS there was a significant positive correlation between S. aureus and disease severity. Results suggest that for some of these patients, treatment with pimecrolimus cream 1% is useful, especially in the head/neck area.

    Tavaborole is a topical antifungal agent approved by the US Food and Drug Administration for the treatment of toenail onychomycosis. The effects of tavaborole on gestation, parturition (delivery, labor), offspring development, and survival during the perinatal and postnatal periods were assessed in mated female rats. Females (F0 generation) were administered single daily oral (gavage) doses of 15, 60, or 100 mg/kg/d from gestation day 6 through lactation day 20. The females were allowed to deliver naturally and rear their offspring until lactation day 21, at which time the F0 females were euthanized. One male and female from each litter were selected (F1 generation) and retained for assessments, including growth, neurobehavior, fertility, and their ability to produce an F2 generation. Reproductive and offspring parameters were determined for the F1 and F2 generations, as applicable. F1 females and F2 pups were euthanized on postnatal day 7. In the F0 females, decreased activity was observed in the 100 mg/kg/d dose group. Excess salivation was observed in the 60 and 100 mg/kg/d dose groups (slight to moderate), however, this finding was not considered adverse. There were no tavaborole-related effects on the growth, viability, development, neurobehavioral assessments, or reproductive performance of the F1 generation. Survivability and mean body weight of the F2 pups were unaffected. The no observed adverse effect level (NOAEL) for maternal toxicity (F0 generation) was 60 mg/kg/d, based on the decreased activity observed in the 100 mg/kg/d dose group. The NOAEL for the offspring effects was ≥100 mg/kg/d, based on the lack of test article-related changes. © The Author(s) 2016.

    Polymorphic light eruption (PLE) is a very frequent photodermatosis whose pathogenesis may involve resistance to ultraviolet (UV)-induced immune suppression. Similar to UV radiation, calcitriol (1,25-dihydroxyvitamin D₃) and its analogues such as calcipotriol have been shown to exhibit immunosuppressive properties. We performed a randomized double-blinded placebo-controlled intraindividual half-body trial (NCT00871052) to investigate the preventive effect of a calcipotriol-containing cream in PLE. Thirteen patients with PLE (10 women, three men; mean age 37 years) pretreated their skin on two symmetrically located test fields with calcipotriol or placebo cream twice daily for 7 days before the start of photoprovocation testing with solar-simulated UV radiation. We established a specific PLE test score [AA + SI + 0·4 P (range 0-12), where AA is affected area score (range 0-4), SI is skin infiltration score (range 0-4) and P is pruritus score on a visual analogue scale (range 0-10)] to quantify PLE severity. Photoprovocation led to PLE lesions in 12/13 (92%) patients. As shown by the PLE test score, compared with placebo calcipotrial pretreatment significantly reduced PLE symptoms in average by 32% (95% confidence interval 21-44%; P = 0·0022, exact Wilcoxon signed-rank test) throughout the observation period starting at 48 h until 144 h after the first photoprovocation exposure. At 48, 72 and 144 h calcipotriol pretreatment resulted in a lower PLE test score in 7 (58%), 9 (75%) and 10 (83%) of the 12 cases, respectively. Considering all time points together, calcipotriol diminished the PLE test score in all 12 photoprovocable patients (P = 0·0005; Wilcoxon signed-rank test). These results suggest a potential therapeutic benefit of topical 1,25-dihydroxyvitamin D₃ analogues as prophylactic treatment in patients with PLE. © 2011 The Authors.

    Topical photodynamic therapy (PDT) has limitations in the treatment of thick skin tumours. The aim of the study was to evaluate the effect of pre-PDT deep curettage on tumour thickness in thick (≥2 mm) basal cell carcinoma (BCC). Additionally, 3-month treatment outcome and change of tumour thickness from diagnosis to treatment were investigated. At diagnosis, mean tumour thickness was 2.3 mm (range 2.0-4.0). Pre- and post-curettage biopsies were taken from each tumour prior to PDT. Of 32 verified BCCs, tumour thickness was reduced by 50% after deep curettage (ρ≤0.001) . Mean tumour thickness was also reduced from diagnosis to treatment. At 3-month followup, complete tumour response was found in 93% and the cosmetic outcome was rated excellent or good in 100% of cases. In conclusion, deep curettage significantly reduces BCC thickness and may with topical PDT provide a favourable clinical and cosmetic short-term outcome.

    Full Text Available Abstract Background Many older people have chronic knee pain. Both topical and oral non- steroidal anti-inflammatory drugs (NSAIDs are commonly used to treat this. Oral NSAIDS are effective, at least in the short term, but can have severe adverse effects. Topical NSAIDs also appear to be effective, at least in the short term. One might expect topical NSAIDs both to be less effective and to have fewer adverse effects than oral NSAIDs. If topical NSAIDs have fewer adverse effects this may outweigh both the reduction in effectiveness and the higher cost of topical compared to oral treatment. Patient preferences may influence the comparative effectiveness of drugs delivered via different routes. Methods TOIB is a randomised trial comparing topical and oral ibuprofen, with a parallel patient preference study. We are recruiting people aged 50 or over with chronic knee pain, from 27 MRC General Practice Research Framework practices across the UK. We are seeking to recruit 283 participants to the RCT and 379 to the PPS. Participants will be followed up for up to two years (with the majority reaching one year. Outcomes will be assessed by postal questionnaire, nurse examination, laboratory tests and medical record searches at one and two years or the end of the study. Discussion This study will provide new evidence on the overall costs and benefits of treating chronic knee pain with either oral or topical ibuprofen. The use of a patient preference design is unusual, but will allow us to explore how preference influences response to a medication. In addition, it will provide more information on adverse events. This study will provide evidence to inform primary care practitioners, and possibly influence practice.

  7. Syntacticized topics in Kurmuk

    Andersen, Torben

    2015-01-01

    This article argues that Kurmuk, a little-described Western Nilotic language, is characterized by a syntacticized topic whose grammatical relation is variable. In this language, declarative clauses have as topic an obligatory preverbal NP which is either a subject, an object or an adjunct....... The grammatical relation of the topic is expressed by a voice-like inflection of the verb, here called orientation. While subject-orientation is morphologically unmarked, object-oriented and adjunct-oriented verbs are marked by a subject suffix or by a suffix indicating that the topic is not subject, and adjunct......-orientation differs from object-orientation by a marked tone pattern. Topic choice largely reflects information structure by indicating topic continuity. The topic also plays a crucial role in relative clauses and in clauses with contrastive constituent focus, in that objects and adjuncts can only be relativized...

    An eco-epidemiological investigation was carried out on Madagascar bat communities to better understand the evolutionary mechanisms and environmental factors that affect virus transmission among bat species in closely related members of the genus Morbillivirus, currently referred to as Unclassified Morbilli-related paramyxoviruses (UMRVs). A total of 947 bats were investigated originating from 52 capture sites (22 caves, 18 buildings, and 12 outdoor sites) distributed over different bioclimatic zones of the island. Using RT-PCR targeting the L-polymerase gene of the Paramyxoviridae family, we found that 10.5% of sampled bats were infected, representing six out of seven families and 15 out of 31 species analyzed. Univariate analysis indicates that both abiotic and biotic factors may promote viral infection. Using generalized linear modeling of UMRV infection overlaid on biotic and abiotic variables, we demonstrate that sympatric occurrence of bats is a major factor for virus transmission. Phylogenetic analyses revealed that all paramyxoviruses infecting Malagasy bats are UMRVs and showed little host specificity. Analyses using the maximum parsimony reconciliation tool CoRe-PA, indicate that host-switching, rather than co-speciation, is the dominant macro-evolutionary mechanism of UMRVs among Malagasy bats.

    Atopic dermatitis is a chronic inflammatory skin disease that may require systemic therapy. Ciclosporin A (CsA) is a widely used, potent immunosuppressant but it is not effective in all patients with atopic dermatitis, and side-effects limit its use. Dupilumab, a fully human anti-interleukin 4 receptor-alpha monoclonal antibody, inhibits signaling of IL-4 and IL-13, key drivers of Type 2/Th2-mediated inflammation, and is approved in the U.S.A. and the European Union for the treatment of inadequately-controlled moderate-to-severe atopic dermatitis in adults. To evaluate efficacy and safety of dupilumab with concomitant topical corticosteroids (TCS) in adults with atopic dermatitis with inadequate response to/intolerance of CsA, or for whom CsA treatment was medically inadvisable. In this 16-week, double-blind, randomized, placebo-controlled, phase III trial, patients were randomized 1 : 1 : 1 to subcutaneous dupilumab 300 mg weekly (qw) or every 2 weeks (q2w) or placebo. All received concomitant medium-potency TCS from Week -2 through Week 16; dosage could be tapered if lesions cleared, or stopped for adverse reactions to TCS. In total, 390 patients were screened, 325 were randomized, and 318 completed the trial. Treatment groups had similar baseline characteristics. Significantly more patients in the dupilumab qw + TCS and q2w + TCS groups achieved ≥ 75% improvement from baseline in the Eczema Area and Severity Index at Week 16 vs. the placebo + TCS group (primary end point) (59·1% and 62·6% vs. 29·6%, respectively; P < 0·001 vs. placebo + TCS, both doses). Other clinical outcomes and atopic dermatitis symptoms were significantly improved in the dupilumab qw + TCS and q2w + TCS groups, including pruritus, pain, sleep disturbance, symptoms of anxiety and depression, and quality of life (QoL). Treatment groups had similar overall rates of adverse events (qw + TCS, q2w + TCS and placebo + TCS groups: 69·1%, 72·0% and 69·4%, respectively) and serious adverse

    Cyclosporine A (Cs) has been used as effective topical therapy for inflammatory dry eye disease since more than a decade. However, due to its lipophilic character, Cs is formulated as emulsions or oily solutions for topical application. This experimental study aimed to test if the use of semifluorinated alkanes (SFAs) as a preservative-free, well-tolerated non-stinging or burning vehicle maintains or even improves the benefits of Cs in the topical therapy of dry-eye disease. Desiccating stress was applied to C57BL/6 mice for 14 consecutive days to induce experimental dry-eye. Cs dissolved in SFA (perfluorobutylpentane = F4H5with 0.5% Ethanol), F4H5 with 0.5% ethanol only, 0.05% Cs (Restasis®), and dexamethasone (Monodex®) were applied three times daily beginning either at day 4 or day 11 of desiccating stress for up to 3 weeks after end of dry-eye induction. In comparison to other groups, Cs/F4H5 demonstrated high efficacy and earlier reduction of corneal staining. In this study, Cs/F4H5 had the ability to maintain conjunctival goblet cell density once applied on day 4. Flow cytometry analysis from cervical lymphnodes demonstrated a significantly lower CD4+ and CD8+ T-cells in the Cs/F4H5 group following 3 weeks of therapy than at baseline, but no difference in regulatory T cells from regional lymphnodes were seen. Overall, compared to a commercially available Cs formulation (Restasis®) and dexamethasone, Cs/F4H5 was shown to be equally effective but with a significantly faster therapeutic response in reducing signs of dry-eye disease in an experimental mouse model.

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

    As described in this article, there are many advances in topical and local anesthesia. Topical and local anesthetics have played a great role in dentistry in alleviating the fears of patients, eliminating pain, and providing pain control. Many invasive procedures would not be performed without the use and advances of topical/local anesthetics. The modern-day dentist has the responsibility of knowing the variety of products on the market and should have at least references to access before, during, and after treatment. This practice ensures proper care with topical and local anesthetics for the masses of patients entering dental offices worldwide. Copyright © 2016 Elsevier Inc. All rights reserved.

    Resveratrol is an effective anti-aging molecule with diverse biologic activity. It functions as a dual antioxidant that can neutralize free radicals and increase intrinsic antioxidant capacity. Additionally resveratrol increases mitochondrial biogenesis and has anti-inflammatory, anti-diabetic, and anti-cancer activity. In this paper we will focus on the use of topically applied resveratrol using a proprietary blend containing 1% resveratrol, 0.5% baicalin, and 1% vitamin E. This stabilized high concentration formulation demonstrates percutaneous absorption and alterations in gene expression such as hemoxygenase-1 (HO-1), vascular endothelial growth factor (VEGFA), and collagen 3 (COL3A1). Clinical assessment showed a statistically significant improvement in fine lines and wrinkles, skin firmness, skin elasticity, skin laxity, hyperpigmentation, radiance, and skin roughness over baseline in 12 weeks. Ultrasound measurements in the periorbital area showed an average improvement of 18.9% in dermal thickness suggesting significant dermal remodeling. These studies confirm that topical resveratrol, baicalin, and vitamin E are valuable ingredient that can be used for skin rejuvenation.

    The Alignable Tight Genomic Clusters (ATGCs) database is a collection of closely related bacterial and archaeal genomes that provides several tools to aid research into evolutionary processes in the microbial world. Each ATGC is a taxonomy-independent cluster of 2 or more completely sequenced genomes that meet the objective criteria of a high degree of local gene order (synteny) and a small number of synonymous substitutions in the protein-coding genes. As such, each ATGC is suited for analysis of microevolutionary variations within a cohesive group of organisms (e.g. species), whereas the entire collection of ATGCs is useful for macroevolutionary studies. The ATGC database includes many forms of pre-computed data, in particular ATGC-COGs (Clusters of Orthologous Genes), multiple sequence alignments, a set of 'index' orthologs representing the most well-conserved members of each ATGC-COG, the phylogenetic tree of the organisms within each ATGC, etc. Although the ATGC database contains several million proteins from thousands of genomes organized into hundreds of clusters (roughly a 4-fold increase since the last version of the ATGC database), it is now built with completely automated methods and will be regularly updated following new releases of the NCBI RefSeq database. The ATGC database is hosted jointly at the University of Iowa at dmk-brain.ecn.uiowa.edu/ATGC/ and the NCBI at ftp.ncbi.nlm.nih.gov/pub/kristensen/ATGC/atgc_home.html.

    The efficacy of the treatment with Certifect ® (containing fipronil 6.26% w/v, amitraz 7.48% w/v, (S)-methoprene 5.63% w/v) applied topically was assessed in 18 dogs diagnosed with clinical generalized demodicosis. Three treatment regimens were compared over a 3-month period. Starting at Day 0, dogs were treated monthly (group 1) or every two weeks (group 2) with the combination of fipronil, amitraz, and (S)-methoprene or with monthly topical applications of the combination of amitraz and metaflumizone (group 3, reference treatment). Clinical examinations including deep skin scrapings were performed every month in order to evaluate the resolution of clinical signs and the reduction in mite counts. On Day 84, the percentage reduction of mite counts in group 1 was 99.8%, whereas no Demodex canis could be detected in groups 2 and 3 (i.e. 100% parasitological efficacy). As a result of the Demodex mite count reduction, the skin condition of the dogs improved significantly in all groups. This study illustrates, that both monthly and bi-weekly treatments with Certifect were effective in treating dogs with generalized demodicosis over a 3-month period. © J.

    2003-01-01

    Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

    The physicochemical properties of the optimized microemulsion and the permeating ability of oxyresveratrol in microemulsion were evaluated, and the efficacy of oxyresveratrol microemulsion in cutaneous herpes simplex virus type 1 (HSV-1) infection in mice was examined. The optimized microemulsion was composed of 10% w/w of isopropyl myristate, 35% w/w of Tween 80, 35% w/w of isopropyl alcohol, and 20% w/w of water. The mean particle diameter was 9.67 ± 0.58 nm, and the solubility of oxyresveratrol in the microemulsion was 196.34 ± 0.80 mg/ml. After accelerated and long-term stability testing, the microemulsion base and oxyresveratrol-loaded microemulsion were stable. The cumulative amount of oxyresveratrol permeating through shed snake skin from microemulsion at 6 h was 93.04 times compared to that of oxyresveratrol from Vaseline, determined at 20% w/w concentration. In cutaneous HSV-1 infection in mice, oxyresveratrol microemulsion at 20%, 25%, and 30% w/w, topically applied five times daily for 7 days after infection, was significantly effective in delaying the development of skin lesions and protecting from death (p microemulsion at 25% and 30% w/w was significantly more effective than that of 30% w/w of oxyresveratrol in Vaseline (p  0.05). These results demonstrated that topical oxyresveratrol microemulsion at 20-30% w/w was suitable for cutaneous HSV-1 mouse infection.

    The aim of this work was to compare the effects of estradiol and genistein treatment on hyaluronic acid (HA) concentration in postmenopausal facial skin. In this study, 30 postmenopausal women were evaluated in a prospective, randomized, double-blind trial. The volunteers were postmenopausal women treated in the Gynecology Department of the Federal University of São Paulo. The participants were divided into two groups: group E, treated with 0.01% 17β-estradiol gel (n = 15), and group G, treated with 4% genistein gel (isoflavones, n = 15). The treatment lasted for 24 consecutive weeks. Preauricular skin biopsies were performed for each participant at baseline (E1 and G1) and after treatment (E2 and G2) to evaluate HA concentration in tissue. The materials were processed using immunohistochemical and biochemical methods. After 24 weeks of treatment, HA concentration increased in both groups, but the effect was greater for estradiol treatment than for genistein treatment. Our data suggest that both treatments may enhance HA concentration in postmenopausal skin but that estrogen produces results that are greater than those produced by isoflavones.

    Combination therapy with pimecrolimus cream 1%, a topical calcineurin inhibitor (TCI), and fluticasone propionate cream 0.05% (FP), a mid-potency topical corticosteroid, may have a synergistic effect for treatment of atopic dermatitis (AD) because their mechanism of action differs. To assess the efficacy of concomitant pimecrolimus twice daily/FP once daily vs. vehicle twice daily/FP once daily in patients with severe AD. An exploratory, 2-week, double-blind, randomized, within-patient study was conducted (n = 45). Two target areas of similar severity, size and location were assessed. Assessments included the modified Eczema Area and Severity Index (0-12 scale) (primary variable), localized investigator global assessment (0-4 scale) and Patients' Self-Assessment of Disease Severity (0-4 scale). Data for all variables were similar for the TCI/FP and vehicle/FP treatments. The efficacy observed for treatment of severe AD flares with this TCI/FP combination regimen was equivalent to that of vehicle/FP.

    Non-steroidal anti-inflammatory drugs (NSAIDs), including diclofenac, are the mainstay of analgesic and anti-inflammatory treatment in dentistry. Diclofenac epolamine [diclofenac N-(2-hydroxyethyl)pyrrolidine; DHEP] is a diclofenac salt with greater water solubility and better cutaneous absorption properties than other commonly used forms of the drug. IBSA has recently developed a mouthwash formulation of DHEP for the topical treatment of inflammatory conditions of the oral cavity. The aim of this study was to compare the efficacy and tolerability of DHEP mouthwash (Osmal®) with that of a reference product (commercially available diclofenac mouthwash). This was a randomized, investigator-blind, parallel-group, controlled, phase III study that enrolled 80 patients with conditions affecting the oral cavity, characterized by an inflammatory component, and eligible for analgesic and anti-inflammatory treatment. Patients were randomized 1 : 1 to DHEP mouthwash (0.103% DHEP in aqueous solution) or to diclofenac mouthwash (0.074% free diclofenac in aqueous solution). The treatment regimen was the same in both groups: 1-minute rinse with 15 mL of mouthwash, twice daily for 7 days. Visits were scheduled at study inclusion (D0), and 3 days (D3) and 7 days (D7) after treatment initiation. During each visit assessments were made of pain severity (using a 5-point semi-quantitative scale and a 100-mm visual analogue scale [VAS]) and inflammatory signs (using a 5-point scale). The primary study endpoint was the change in pain severity scores from D0 to D3 and D7. Secondary endpoints included effects of treatment on inflammation score, quality of sleep, compliance with treatment and the safety and tolerability of treatment. The two treatment arms were homogeneous in terms of patient characteristics. The most prevalent oral condition was gingivitis. Overall both topical treatments were effective in alleviating pain and inflammation, as evidenced by decreases in pain and

  12. Topical antifungal agents: an update.

    So many topical antifungal agents have been introduced that it has become very difficult to select the proper agent for a given infection. Nonspecific agents have been available for many years, and they are still effective in many situations. These agents include Whitfield's ointment, Castellani paint, gentian violet, potassium permanganate, undecylenic acid and selenium sulfide. Specific antifungal agents include, among others, the polyenes (nystatin, amphotericin B), the imidazoles (metronidazole, clotrimazole) and the allylamines (terbinafine, naftifine). Although the choice of an antifungal agent should be based on an accurate diagnosis, many clinicians believe that topical miconazole is a relatively effective agent for the treatment of most mycotic infections. Terbinafine and other newer drugs have primary fungicidal effects. Compared with older antifungal agents, these newer drugs can be used in lower concentrations and shorter therapeutic courses. Studies are needed to evaluate the clinical efficacies and cost advantages of both newer and traditional agents.

    Cutaneous leishmaniasis is one of the highly prevalent endemic diseases in the Middle East and North Africa. Many treatment modalities have been recommended for this condition but success rates remain limited. Herbal remedies have also been used for treatment but evidence-based clinical trials with these products are sparse. In-vitro and in-vivo studies have shown the anti-leishmanial and curative effects of extract of fruits and leaves of Juniperus excelsa (J. excelsa). The aim of this study was to determine the efficacy of topical J. excelsa M. Bieb extract as an adjuvant to cryotherapy for the treatment of human CL. This study was designed as a two-arm triple-blind randomized placebo-controlled clinical trial using a parallel design. Seventy-two patients with clinical diagnosis of CL confirmed by leishmania smears were allocated to receive either a topical formulation of leaf of J. excelsa extract (group A) or placebo (group B) for 3 months. Both groups received cryotherapy as baseline standard treatment. Patients were evaluated before and weekly after the intervention was initiated until complete cure. Overall, 82% of patients in group A, experienced complete cure and 9% of them had partial cure. On the other hand, 34% in group B reported complete cure, while 14% of them had partial cure at the end of treatment protocol with a significant difference between the two groups (Pcryotherapy for accelerating the time to cure in addition to increasing the complete cure rate in CL.

  18. Discriminative Relational Topic Models.

    2015-05-01

    Relational topic models (RTMs) provide a probabilistic generative process to describe both the link structure and document contents for document networks, and they have shown promise on predicting network structures and discovering latent topic representations. However, existing RTMs have limitations in both the restricted model expressiveness and incapability of dealing with imbalanced network data. To expand the scope and improve the inference accuracy of RTMs, this paper presents three extensions: 1) unlike the common link likelihood with a diagonal weight matrix that allows the-same-topic interactions only, we generalize it to use a full weight matrix that captures all pairwise topic interactions and is applicable to asymmetric networks; 2) instead of doing standard Bayesian inference, we perform regularized Bayesian inference (RegBayes) with a regularization parameter to deal with the imbalanced link structure issue in real networks and improve the discriminative ability of learned latent representations; and 3) instead of doing variational approximation with strict mean-field assumptions, we present collapsed Gibbs sampling algorithms for the generalized relational topic models by exploring data augmentation without making restricting assumptions. Under the generic RegBayes framework, we carefully investigate two popular discriminative loss functions, namely, the logistic log-loss and the max-margin hinge loss. Experimental results on several real network datasets demonstrate the significance of these extensions on improving prediction performance.

    Atopic keratoconjunctivitis (AKC) is a chronic ocular surface non-infectious inflammatory condition that atopic dermatitis patients may suffer at any time point in the course of their dermatologic disease and is independent of its degree of severity. AKC is usually not self resolving and it poses a higher risk of corneal injuries and severe sequelae. Management of AKC should prevent or treat corneal damage. Although topical corticosteroids remain the standard treatment for patients with AKC, prolonged use may lead to complications. Topical cyclosporine A (CsA) may improve AKC signs and symptoms, and be used as a corticosteroid sparing agent. To determine the efficacy and gather evidence on safety from randomised controlled trials (RCTs) of topical CsA in patients with AKC. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 6), MEDLINE (January 1946 to July 2012), EMBASE (January 1980 to July 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to July 2012), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (January 1937 to July 2012), OpenGrey (System for Information on Grey Literature in Europe) (www.opengrey.eu/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en), the IFPMA Clinical Trials Portal (http://clinicaltrials.ifpma.org/no_cache/en/myportal/index.htm) and Web of Science Conference Proceedings Citation Index- Science (CPCI-S).

    2010-03-01

    Nanotechnology is a rapidly growing discipline that capitalizes on the unique properties of matter engineered on the nanoscale. Vehicles incorporating nanotechnology have led to great strides in drug delivery, allowing for increased active ingredient stability, bioavailability, and site-specific targeting. Botulinum toxin has historically been used for the correction of neurological and neuromuscular disorders, such as torticollis, blepharospasm, and strabismus. Recent dermatological indications have been for the management of axillary hyperhydrosis and facial rhytides. Traditional methods of botulinum toxin delivery have been needle-based. These have been associated with increased pain and cost. Newer methods of botulinum toxin formulation have yielded topical preparations that are bioactive in small pilot clinical studies. While there are some risks associated with topical delivery, the refinement and standardization of delivery systems and techniques for the topical administration of botulinum toxin using nanotechnology is anticipated in the near future.

    Topical cosmetic agents may play a role in the management of facial seborrheic dermatitis by reducing inflammation and scale production. Advanced digital photography, equipped with technology able to provide a detailed evaluation of red skin components corresponding to vascular flare (erythema-directed digital photography), is a useful tool for evaluation of erythema in patients affected by inflammatory dermatoses. The aim of this study was to assess the efficacy and safety of a new cosmetic topical gel containing piroctone olamine, lactoferrin, glycero-phospho-inositol, and Aloe vera for the treatment of facial seborrheic dermatitis by clinical and advanced digital photography evaluation. An open-label, prospective, clinical trial was conducted on 25 patients with mild to moderate facial seborrheic dermatitis. Subjects were instructed to apply the gel twice daily for 45 days. The clinical efficacy was evaluated by measuring at baseline, at day 15 and 45 the degree of desquamation (by clinical examination) and erythema (by digital photography technology via VISIA-CR™ system equipped with RBX™), using a 5-point severity scale, and pruritus (by subject-completed Visual Analogue Scale; scale from 0 to 100 mm). Finally, at baseline and at the end of the study, IGA (Investigator Global Assessment) was performed using a 5-point severity scale (from 0 = worsening to 4 = excellent response). At the end of treatment, a significant reduction (P80% improvement) was recorded in 47.9% of patients, with no case of worsening. No signs of local intolerance were documented. The tested cosmetic topical gel was effective in treating mild to moderate seborrheic dermatitis of the face. Erythema-directed digital photography may represent a noteworthy tool for the therapeutic monitoring of facial seborrheic dermatitis and an important adjunct aid in the dermatologic clinical practice.

  5. Influence of continental history on the ecological specialization and macroevolutionary processes in the mammalian assemblage of South America: Differences between small and large mammals

    drivers of mammalian evolution. Nevertheless, deviations from the expectations indicate the importance of differences in reproductive traits and paleobiogeographic history for the macroevolutionary processes involved. In the case of South American mammals, the Pliocene Great American Biotic Interchange strongly influences the ecological characteristics of this assemblage. Furthermore, the Andes have acted as a fertile ground for speciation in environments prone to vicariance. Finally, the micromammals appear as more prone to biomic specialization than larger species. These factors are responsible for some of the differences found between South America and Africa in the studied pattern. For example, the extensive South American mountain ranges favour a higher number of combinations of inhabited biomes in comparison with Africa.

    Full Text Available Justin J Gandy, Jacques R Snyman, Constance EJ van RensburgDepartment of Pharmacology, Faculty of Health Sciences, University of Pretoria, Pretoria, South AfricaBackground: The purpose of this study was to evaluate the efficacy and safety of carbohydrate-derived fulvic acid (CHD-FA in the treatment of eczema in patients two years and older.Methods: In this single-center, double-blind, placebo-controlled, parallel-group comparative study, 36 volunteers with predetermined eczema were randomly assigned to receive either the study drug or placebo twice daily for four weeks.Results: All safety parameters remained within normal limits, with no significant differences in either group. Significant differences were observed for both severity and erythema in the placebo and CHD-FA treated groups, and a significant difference was observed for scaling in the placebo-treated group. With regard to the investigator assessment of global response to treatment, a significant improvement was observed in the CHD-FA group when compared with the placebo group. A statistically significant decrease in visual analog scale score was observed in both groups, when comparing the baseline with the final results.Conclusion: CHD-FA was well tolerated, with no difference in reported side effects other than a short-lived burning sensation on application. CHD-FA significantly improved some aspects of eczema. Investigator assessment of global response to treatment with CHD-FA was significantly better than that with emollient therapy alone. The results of this small exploratory study suggest that CHD-FA warrants further investigation in the treatment of eczema.Keywords: fulvic acid, eczema, anti-inflammatory, efficacy, safety

  14. Topical immunomodulators in dermatology

    2004-04-01

    Full Text Available Topical immunomodulators are agents that regulate the local immune response of the skin. They are now emerging as the therapy of choice for several immune-mediated dermatoses such as atopic dermatitis, contact allergic dermatitis, alopecia areata, psoriasis, vitiligo, connective tissue disorders such as morphea and lupus erythematosus, disorders of keratinization and several benign and malignant skin tumours, because of their comparable efficacy, ease of application and greater safety than their systemic counterparts. They can be used on a domiciliary basis for longer periods without aggressive monitoring. In this article, we have discussed the mechanism of action, common indications and side-effects of the commonly used topical immunomodulators, excluding topical steroids. Moreover, newer agents, which are still in the experimental stages, have also been described. A MEDLINE search was undertaken using the key words "topical immunomodulators, dermatology" and related articles were also searched. In addition, a manual search for many Indian articles, which are not indexed, was also carried out. Wherever possible, the full article was reviewed. If the full article could not be traced, the abstract was used.

    In applications we may want to compare different document collections: they could have shared content but also different and unique aspects in particular collections. This task has been called comparative text mining or cross-collection modeling. We present a differential topic model for this application that models both topic differences and similarities. For this we use hierarchical Bayesian nonparametric models. Moreover, we found it was important to properly model power-law phenomena in topic-word distributions and thus we used the full Pitman-Yor process rather than just a Dirichlet process. Furthermore, we propose the transformed Pitman-Yor process (TPYP) to incorporate prior knowledge such as vocabulary variations in different collections into the model. To deal with the non-conjugate issue between model prior and likelihood in the TPYP, we thus propose an efficient sampling algorithm using a data augmentation technique based on the multinomial theorem. Experimental results show the model discovers interesting aspects of different collections. We also show the proposed MCMC based algorithm achieves a dramatically reduced test perplexity compared to some existing topic models. Finally, we show our model outperforms the state-of-the-art for document classification/ideology prediction on a number of text collections.

Currently, there is no widely accepted treatment for the disorder, but it is usually treated with bleaching agents because it is considered a variant of inflammatory hyperpigmentation. The purpose of this study was to assess the efficacy of niacinamide 4% and desonide 0.05% emulsions compared with placebo in the treatment of axillary hyperpigmentation.Methods: Twenty-four women aged 19–27 years with hyperpigmented axillae (phototype III–V were randomly assigned to receive the study treatments in the axillary region. Improvement was assessed at baseline, then clinically and by colorimetry 9 weeks later. Quantitative evaluation including melanin, inflammatory infiltrates, NKI/Beteb, CD1a, CD68, and collagen type IV content was performed by histochemistry and immunohistochemistry, assisted by computerized morphometric analysis.Results: Both niacinamide and desonide induced significant colorimetric improvement compared with placebo; however, desonide showed a better depigmenting effect than niacinamide. A good to excellent response was achieved in 24% of cases for niacinamide, 30% for desonide, and 6% for placebo. We observed a marked disruption of the basal membrane in axillary hyperpigmentation and an inflammatory infiltrate that improved after treatment. Decreased pigmentation in the desonide-treated axillae was associated with recovery of disruption at the basal membrane

Development of nitrogen mustard formulations and treatment regimens has been studied extensively over the last 40 years. In the last 5 years, a new gel formulation has been developed that is associated with a decrease in delayed hypersensitivity reactions. The authors in this review found that while the gel formulation may result in a decrease of allergic contact dermatitis, this advantage has been replaced by a higher number of irritant contact reactions and a decrease in complete response rate. The gel formulation has a complete response rate of 13.8%, which is a decrease in efficacy when compared to aqueous-based preparations of similar concentrations.

    The aim of this observational study was to evaluate the efficacy, tolerability and methods of application of ialuronic acid associated with argentic sulphadiazine (Connettivina Plus) in routine clinical activity, on a target of "complex" patients with pressure sores, for the most realistic assessment possible. The study comprised 127 patients hospitalized between January 2006 and December 2007, who received ialuronic acid associated with argentic sulphadiazine in addition to the standard treatment. Inclusion criteria were th presence of at least one stage 2 or 3 pressure sore (NPUAP '89 classification), pressure sore that the researcher had already decided to treat using ialuronic acid associated with argentic sulphadiazine , according to hospital protocol, area of the lesion less than 25cm2, patient age 18 years or more, informed patient consensus. Patients with these characteristics were , however, excluded if they did not provide written consent or if they had one of the following: presence of pressure sores with escara, concomitant neoplastic disease, concomitant insulin-dependent diabetes or other pathologies that interfere with skin regeneration, allergic diasthesis (acclaimed or presumed) to ialuronic acid - argentic sulphadiazine, inability / refusal to undergo all the subsequent controls required by the study. Improvement or complete healing of the pressure sores was observed in 67% of patients at early follow-up (10 days), increasing to 76% and 87% at 20 and 35 day controls respectively. The Push tool further improved in patients who carried on treatment. Use of ialuronic acid associated with argentic sulphadiazine was effective for treating grade 2-3 pressure sores in patients with chronic lesions and its efficacy was confirmed in association with both advanced and traditional types of medication.

  1. Incorporating Topic Assignment Constraint and Topic Correlation Limitation into Clinical Goal Discovering for Clinical Pathway Mining

    Full Text Available Clinical pathways are widely used around the world for providing quality medical treatment and controlling healthcare cost. However, the expert-designed clinical pathways can hardly deal with the variances among hospitals and patients. It calls for more dynamic and adaptive process, which is derived from various clinical data. Topic-based clinical pathway mining is an effective approach to discover a concise process model. Through this approach, the latent topics found by latent Dirichlet allocation (LDA represent the clinical goals. And process mining methods are used to extract the temporal relations between these topics. However, the topic quality is usually not desirable due to the low performance of the LDA in clinical data. In this paper, we incorporate topic assignment constraint and topic correlation limitation into the LDA to enhance the ability of discovering high-quality topics. Two real-world datasets are used to evaluate the proposed method. The results show that the topics discovered by our method are with higher coherence, informativeness, and coverage than the original LDA. These quality topics are suitable to represent the clinical goals. Also, we illustrate that our method is effective in generating a comprehensive topic-based clinical pathway model.

    Anal cancer is an increasing issue in HIV-positive men who have sex with men (MSM). Screening for its precursor, anal intraepithelial neoplasia (AIN), is subject of discussion. Current treatment options are suboptimum and have not been compared in a prospective trial. We compared efficacy and side-effects of imiquimod, topical fluorouracil, and electrocautery for the treatment of AIN. In this open-label randomised trial, we included HIV-positive MSM older than 18 years visiting the HIV outpatient clinic of the Academic Medical Center, Amsterdam, Netherlands. Patients with histologically confirmed AIN were randomly assigned to receive either 16 weeks of imiquimod (three times a week), 16 weeks of topical fluorouracil (twice a week), or monthly electrocautery for 4 months. Randomisation was done with random block sizes of three and six, stratified for AIN grade (AIN grades 1, 2, or 3) and AIN location (peri-anal or intra-anal). Participants were assessed by high-resolution anoscopy 4 weeks after treatment. Responding patients returned for follow-up 24 weeks, 48 weeks, and 72 weeks after treatment. The primary endpoint was histological resolution of AIN measured 4 weeks after treatment and AIN recurrence at week 24, week 48, and week 72 after treatment. The primary analysis was done in a modified intention-to-treat population, including all patients who had received their assigned treatment at least once. The trial is registered at the Netherlands Trial Register, number NTR1236. Between Aug 12, 2008, and Dec 1, 2010, we screened 388 HIV-positive MSM for AIN by high resolution anoscopy. Of the 246 (63%) patients who had AIN, 156 (63%) were randomly assigned to either receive imiquimod (54 patients), topical fluorouracil (48 patients), or electrocautery (46 patients) following withdrawing of consent by eight patients. Modified intention-to-treat analysis showed a complete response in 13 (24%, 95% CI 15-37) patients in the imiquimod group, eight (17%, 8-30) of patients

    The study aimed to formulate and evaluate levofloxacin hemihydrate ocular in situ gels along with freshly prepared disappearing preservative reported to be safer to human eyes. Formulae were prepared using thermosensitive (PF127 and PF68) or ion-activated (Gelrite) polymers. They were evaluated for gelation temperature (GT), capacity, content uniformity, pH, rheological behavior, in vitro drug release with kinetic analysis. Best formulae were exposed to storage effect to select the optimum formula that was subjected to different sterilization methods and in vivo evaluation. The prepared disappearing preservative (sodium perborate monohydrate) proved to be active oxidative preservative and compatible with our formulae. F9 (24% PF127, 15% PF 68, 0.5% levofloxacin hemihydrate, and 0.0025% sodium perborate monohydrate) showed prolonged drug release (12 h), acceptable GT, viscosity, and pH. It remained stable over 3 months at two temperatures and was best sterilized by filtration. It showed longer residence time (12 h) in rabbits' eye fluids compared with the Levoxin® eye drops (4 h). This successful attempt of using thermo-gelling system along with a disappearing type of preservatives would allow the use of these systems to achieve sustained release of antimicrobial drugs with minimum risk of eye damage improving patient compliance and treatment efficacy.

    The risk of penetrating, traumatic injury occurring in a chemically contaminated environment cannot be discounted. Should a traumatic injury be contaminated with a chemical warfare (CW) agent, it is likely that standard haemostatic treatment options would be complicated by the need to decontaminate the wound milieu. Thus, there is a need to develop haemostatic products that can simultaneously arrest haemorrhage and decontaminate CW agents. The purpose of this study was to evaluate a number of candidate haemostats for efficacy as skin decontaminants against three CW agents (soman, VX and sulphur mustard) using an in vitro diffusion cell containing undamaged pig skin. One haemostatic product (WoundStat™) was shown to be as effective as the standard military decontaminants Fuller's earth and M291 for the decontamination of all three CW agents. The most effective haemostatic agents were powder-based and use fluid absorption as a mechanism of action to sequester CW agent (akin to the decontaminant Fuller's earth). The envisaged use of haemostatic decontaminants would be to decontaminate from within wounds and from damaged skin. Therefore, WoundStat™ should be subject to further evaluation using an in vitro model of damaged skin. Copyright © 2014 Crown copyright. Journal of Applied Toxicology © 2014 John Wiley & Sons, Ltd.

    2003-07-01

    With the increasing pressure on a more effective and sustainable use of water resources, those water treatment technologies become more and more important which will allow for a recycling of wastewater for agricultural and/or industrial purposes. The so-called advanced oxidation processes (AOP's) belong to these technologies as they offer the potential of a complete conversion of the water pollutants to carbon dioxide, water and mineral salts. Despite the progress that has been achieved in understanding and applying AOP's, the most significant disadvantages of the oxidation technologies are the high investment and operating costs. As these technologies are the high investment and operating costs. As these technologies are based on radical reactions, more effective means of producing radicals and a deeper insight in the reaction pathways will be the key for generating radicals at lower costs as well as choosing the optimum process conditions and defining the applications where AOP's are most competitive. Two national, three international conferences with the publication of their papers in water science and technology (1997 and 2001) as well as the foundation of the IWA Specialist Group on AOP's in 2001 demonstrate the success and the necessity of this conference series. It is designed to bring forward the most recent advances in the fundamentals as well as the development and the application of AOP's especially in the field of water recycling reuse. It will help to disseminate new achievements in these areas and to identify future research and development needs. The increased number of interesting papers submitted will be the basis for a successful, fruitful and hopefully critical conference in Goslar. (orig.)

    Data from early-stage studies suggested that interleukin (IL)-4 and IL-13 are requisite drivers of atopic dermatitis, evidenced by marked improvement after treatment with dupilumab, a fully-human monoclonal antibody that blocks both pathways. We aimed to assess the efficacy and safety of several dose regimens of dupilumab in adults with moderate-to-severe atopic dermatitis inadequately controlled by topical treatments. In this randomised, placebo-controlled, double-blind study, we enrolled patients aged 18 years or older who had an Eczema Area and Severity Index (EASI) score of 12 or higher at screening (≥16 at baseline) and inadequate response to topical treatments from 91 study centres, including hospitals, clinics, and academic institutions, in Canada, Czech Republic, Germany, Hungary, Japan, Poland, and the USA. Patients were randomly assigned (1:1:1:1:1:1), stratified by severity (moderate or severe, as assessed by Investigator's Global Assessment) and region (Japan vs rest of world) to receive subcutaneous dupilumab: 300 mg once a week, 300 mg every 2 weeks, 200 mg every 2 weeks, 300 mg every 4 weeks, 100 mg every 4 weeks, or placebo once a week for 16 weeks. We used a central randomisation scheme, provided by an interactive voice response system. Drug kits were coded, providing masking to treatment assignment, and allocation was concealed. Patients on treatment every 2 weeks and every 4 weeks received volume-matched placebo every week when dupilumab was not given to ensure double blinding. The primary outcome was efficacy of dupilumab dose regimens based on EASI score least-squares mean percentage change (SE) from baseline to week 16. Analyses included all randomly assigned patients who received one or more doses of study drug. This trial is registered with ClinicalTrials.gov, number NCT01859988. Between May 15, 2013, and Jan 27, 2014, 452 patients were assessed for eligibility, and 380 patients were randomly assigned. 379 patients received one or more

    To evaluate the clinical and bacteriological efficacy of topical retapamulin ointment 1% versus oral linezolid in the treatment of patients with secondarily infected traumatic lesions (SITLs; excluding abscesses) or impetigo due to methicillin-resistant Staphylococcus aureus (MRSA). A randomized, double-blind, double-dummy, multicenter, comparative study (NCT00852540). Patients recruited from 36 study centers in the United States. Patients 2 months or older with SITL (including secondarily infected lacerations or sutured wounds) or impetigo (bullous and nonbullous) suitable for treatment with a topical antibiotic, with a total Skin Infection Rating Scale score of 8 or greater, including a pus/exudate score of 3 or greater. Patients received retapamulin ointment 1% (plus oral placebo), twice daily for 5 days or oral linezolid (plus placebo ointment) 2 or 3 times daily for 10 days. Primary end point: clinical response (success/failure) at follow-up in patients with MRSA at baseline (per-protocol population). Secondary efficacy end points: clinical and microbiologic response and outcome at follow-up and end of therapy; therapeutic response at follow-up. The majority of patients had SITL (70.4% [188/267] and 66.4% [91/137] in the retapamulin and linezolid groups, respectively; intent-to-treat clinical population). Clinical success rate at follow-up was significantly lower in the retapamulin versus the linezolid group (63.9% [39/61] vs 90.6% [29/32], respectively; difference in success rate -26.7%; 95% CI, -45.7 to -7.7). Clinical success rate at follow-up in the per-protocol MRSA population was significantly lower in the retapamulin versus the linezolid group. It could not be determined whether this was related to study design, bacterial virulence, or retapamulin activity.

    Many patients with osteoarthritis (OA) experience side effects with available systemic therapies, some of which can be life threatening. The widespread use of nonsteroidal anti-inflammatory drugs (NSAIDs), often without prescription, is concerning given their potential risks. New treatments for OA are therefore required. This review discusses evidence supporting the use of TDT 064, a drug-free, topical gel containing ultra-deformable phospholipid vesicles (Sequessome * vesicles), for OA-associated pain. Preclinical and clinical studies investigating TDT 064 in patients with OA-associated knee pain were identified in searches of PubMed and congress abstracts. The ultra-deformable phospholipid vesicles (sequessome vesicles) in TDT 064 pass through the skin intact to reach the synovial space within the joint. The mechanism of action is not yet certain, but the phospholipid-based structure of these ultra-deformable phospholipid vesicles, and the observation that they localize to the cartilage surface, support biolubrication as a possible mechanism of action of TDT 064. Data from randomized, phase III studies in OA knee pain in which TDT 064 was used as the drug-free vehicle control for IDEA-033 (ketoprofen in ultra-deformable phospholipid vesicles) demonstrate a marked and consistent response to TDT 064 in terms of pain, stiffness, and function. In a 12 week study of >1300 patients, the effects of TDT 064 on pain and function were statistically noninferior to those of oral celecoxib, and superior to oral placebo. TDT 064 was well tolerated in all studies, and adverse events were typically mild-to-moderate effects on the skin. Evidence from clinical studies supports the use of TDT 064 as a drug-free topical treatment for patients with OA. Further experience with TDT 064, particularly among patients with comorbidities or NSAID contraindications, will provide more information on its potential use.

    2015-01-01

    This study examined the nature of topic transition problems associated with acquired progressive dysarthric speech in the everyday conversation of people with motor neurone disease. Using conversation analytic methods, a video collection of five naturally occurring problematic topic transitions was identified, transcribed and analysed. These were extracted from a main collection of over 200 other-initiated repair sequences and a sub-set of 15 problematic topic transition sequences. The sequences were analysed with reference to how the participants both identified and resolved the problems. Analysis revealed that topic transition by people with dysarthria can prove problematic. Conversation partners may find transitions problematic not only because of speech intelligibility but also because of a sequential disjuncture between the dysarthric speech turn and whatever topic has come prior. In addition the treatment of problematic topic transition as a complaint reveals the potential vulnerability of people with dysarthria to judgements of competence. These findings have implications for how dysarthria is conceptualized and how specific actions in conversation, such as topic transition, might be suitable targets for clinical intervention.

    Macias, Sergio

    2005-01-01

    Specialized as it might be, continuum theory is one of the most intriguing areas in mathematics. However, despite being popular journal fare, few books have thoroughly explored this interesting aspect of topology. In Topics on Continua, Sergio Macías, one of the field's leading scholars, presents four of his favorite continuum topics: inverse limits, Jones's set function T, homogenous continua, and n-fold hyperspaces, and in doing so, presents the most complete set of theorems and proofs ever contained in a single topology volume. Many of the results presented have previously appeared only in research papers, and some appear here for the first time. After building the requisite background and exploring the inverse limits of continua, the discussions focus on Professor Jones''s set function T and continua for which T is continuous. An introduction to topological groups and group actions lead to a proof of Effros''s Theorem, followed by a presentation of two decomposition theorems. The author then offers an...

    To evaluate the safety and efficacy of topical loteprednol etabonate (LE) 0.5% compared with cyclosporine A (CsA) 0.05% for the prophylaxis and treatment of dry eye syndrome (DES) after hematopoietic stem cell transplantation (HSCT). Seventy-five patients were randomized to LE (n = 76 eyes of 38 patients) or CsA (n = 74 eyes of 37 patients) pre-HSCT. Lissamine green and fluorescein staining, tear break-up time, tear osmolarity (Osm), Schirmer score (Sch), intraocular pressure, visual acuity, and Ocular Surface Disease Index were assessed pre-HSCT, 3, 6, 9, and 12 months post-HSCT. There were no differences in DES incidence (P = 0.22; log-rank test) or progression (P = 0.41; log-rank test) between the 2 treatment arms during the course of the study. Among eyes with no DES at enrollment, the Kaplan-Meier analysis yielded a 90% rate of DES development in cyclosporine-treated eyes and a 79% rate of DES development in LE-treated eyes by 12 months post-HSCT. The Kaplan-Meier analysis of eyes with DES at enrollment demonstrated a 38% rate of disease progression among cyclosporine-treated eyes and a 26% rate of disease progression among loteprednol-treated eyes by 12 months. No patient in either group had an elevation of 10 mm Hg or greater from baseline at any study visit, and no patients had their treatment discontinued for elevation in intraocular pressure. Pre-HSCT initiation of LE 0.5% appears to be safe and may be as effective as CsA 0.5% for the treatment and prophylaxis of DES following HSCT.

    This book analyzes the impact of quiescent phases on biological models. Quiescence arises, for example, when moving individuals stop moving, hunting predators take a rest, infected individuals are isolated, or cells enter the quiescent compartment of the cell cycle. In the first chapter of Topics in Mathematical Biology general principles about coupled and quiescent systems are derived, including results on shrinking periodic orbits and stabilization of oscillations via quiescence. In subsequent chapters classical biological models are presented in detail and challenged by the introduction of quiescence. These models include delay equations, demographic models, age structured models, Lotka-Volterra systems, replicator systems, genetic models, game theory, Nash equilibria, evolutionary stable strategies, ecological models, epidemiological models, random walks and reaction-diffusion models. In each case we find new and interesting results such as stability of fixed points and/or periodic orbits, excitability...

Although topical steroid addiction or red burning skin syndrome had been mentioned as possible side effects of topical steroids in a 2006 review article in the Journal of the American Academy of Dermatology, no statement was made regarding this illness in the new guidelines. This suggests that there are still controversies regarding this illness. Here, we describe the clinical features of topical steroid addiction or red burning skin syndrome, based on the treatment of many cases of the illness. Because there have been few articles in the medical literature regarding this illness, the description in this article will be of some benefit to better understand the illness and to spur discussion regarding topical steroid addiction or red burning skin syndrome.

    Topical antibiotics are routinely used in emergency rooms to treat corneal trauma, although no published evidence supports this treatment. In a noncomparative clinical trial, 351 patients with corneal epithelial injuries were treated without antibiotics. The infection rate was 0.7%, suggesting that such injuries can be safely and effectively managed without antibiotics. A comparative clinical trial is neither warranted nor feasible.

  11. Antimicrobial topical agents used in the vagina.

    Science.gov (United States)

    Frey Tirri, Brigitte

    2011-01-01

    Vaginally applied antimicrobial agents are widely used in the vagina in women with lower genital tract infections. An 'antimicrobial' is a general term that refers to a group of drugs that are effective against bacteria, fungi, viruses and protozoa. Topical treatments can be prescribed for a wide variety of vaginal infections. Many bacterial infections, such as bacterial vaginosis, desquamative inflammatory vaginitis or, as some European authors call it, aerobic vaginitis as well as infection with Staphylococcus aureus or group A streptococci, may be treated in this way. Candida vulvovaginitis is a fungal infection that is very amenable to topical treatment. The most common viral infections which can be treated with topical medications are condylomata acuminata and herpes simplex. The most often encountered protozoal vaginitis, which is caused by Trichomonas vaginalis, may be susceptible to topical medications, although this infection is treated systemically. This chapter covers the wide variety of commonly used topical antimicrobial agents for these diseases and focuses on the individual therapeutic agents and their clinical efficacy. In addition, potential difficulties that can occur in practice, as well as the usage of these medications in the special setting of pregnancy, are described in this chapter. Copyright © 2011 S.

  12. Comparative efficacy on dogs of a single topical treatment with fipronil/(S-methoprene or weekly physiological hygiene shampoos against Ctenocephalides felis in a simulated flea-infested environment

    Directory of Open Access Journals (Sweden)

    Beugnet F.

    2012-05-01

    Full Text Available Flea infestations of pets continue to persist due to the lack of knowledge of flea biology and ecology. It is not unusual that pet owners believe regular hygiene, such as shampooing their dogs can replace regular insecticidal treatment. The objective of this study was to compare in a flea simulated environment, modelling exposure similar to that found in a home, that the use of regular physiological shampoo does not control fleas adequately when compared to a long acting topical formulation. Three groups of six dogs were formed: one untreated control group, one group treated monthly with the topical formulation of fipronil/(S-methoprene, and a third group treated weekly with a hygiene shampoo. All dogs were infested with adult unfed Ctenocephalides felis fleas (200 ± 5 on Days -28 and -21. Each animal’s sleeping box was fitted with a plastic cup mounted to the inside roof of the box. The sleeping bench of each animal was covered with a carpet to accommodate flea development. The dogs were maintained in their kennels throughout the study. In order to maintain the environmental flea challenge, C. felis pupae (100 ± 5 were placed in the plastic cup in each animal’s sleeping box on Days -14, -7, 0, 7, 14, 21, 28, 35 and 42. The dogs were combed and fleas counted weekly on Days -1, 3, 10, 17, 24, 31, 38, 45, and 51. The fleas were placed immediately back on the dogs. On Day 60, fleas were counted and removed. Flea infestations in the untreated control group at each count averaged between 46.2 and 74.2 fleas throughout the study. The average number of fleas infesting dogs was significantly different (p < 0.05 between the untreated and the two treatment groups and between the two treatment groups at all counts throughout the two months study (Days 3, 10, 17, 24, 31, 38, 45, 51 and 60. The efficacy was never below 99.1% in the fipronil/(S-methoprene group, and efficacy in the shampoo group was never above 79.2%. Weekly shampooing in treatment

  13. Topics in statistical mechanics

    International Nuclear Information System (INIS)

    Elser, V.

    1984-05-01

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references

  14. Superconcentration and related topics

    CERN Document Server

    Chatterjee, Sourav

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

  15. Topics in broken supersymmetry

    International Nuclear Information System (INIS)

    Lee, I.H.

    1984-01-01

    Studies on two topics in the framework of broken supersymmetry are presented. Chapter I is a brief introduction in which the motivation and the background of this work are discussed. In Chapter II, the author studies the decay K + → π + γγ in models with spontaneous supersymmetry breaking and find that it is generally suppressed relative to the decay K + → π + anti nu nu of the conventional model, except possibly for a class of models where the scalar quark masses are generated by radiative corrections from a much larger supersymmetry breaking scale. For a small range of scalar quark and photino mass parameters, the cascade decay process K + → π + π 0 → π + γγ will become dominant over the anti nu nu mode. The author also comments on the possibility of probing the neutrino mass through the K + → π + π 0 → π + anti nu nu cascade decay. Chapter III is concerned with the implications of explicit lepton number violating soft operators in a general low energy effective theory with softly broken supersymmetry

  16. Topics in supersymmetric theories

    International Nuclear Information System (INIS)

    Nemeschansky, D.D.

    1984-01-01

    This thesis discusses four different topics in supersymmetric theories. In the first part models in which supersymmetry is broken by the Fayet-Iliopoulos mechanism are considered. The possibility that scalar quark and lepton masses might arise radiatively in such theories is explored. In the second part supersymmetric grand unified models with a sliding singlet are considered. The author reviews the argument that the sliding singlet does not work in models with large supersymmetry breaking. Then he considers the possibility of using a sliding singlet with low energy supersymmetry breaking. The third part of the thesis deals with the entropy problem of supersymmetric theories. Most supersymmetric models possess a decoupled particle with mass of order 100 GeV which is copiously produced in the early universe and whose decay produces huge amounts of entropy. The author shows how this problem can be avoided in theories in which the hidden sector contains several light fields. In the fourth part effective Lagrangians for supersymmetric theories are studied. The anomalous pion interaction for supersymmetric theories is written down. General properties of this term are studied both on compact and non-compact manifolds

    1986-01-01

    This dissertation deals with several topics of field theory. Chapter I is a brief outline of the work presented in the next chapters. In chapter II, the Gauss-Bonnet-Chern theorem for manifolds with boundary is computed using the path integral representation of the Witten index for supersymmetric quantum mechanical systems. In chapter III the action of N = 2 (Poincare) supergravity is obtained in terms of N = 1 superfields. In chapter IV, N = 2 supergravity coupled to the (abelian) vector multiplet is projected into N - 1 superspace. There, the resulting set of constraints is solved in terms of unconstrained prepotential and the action in terms of N = 1 superfields is constructed. In chapter V the set of constraints for N = 2 conformal supergravity is projected into N = 1 superspace and solved in terms of N = 1 conformal supergravity fields a d matter prepotentials. In chapter VI the role of magnetic monopoles in the phase structure of the change one fixed length abelian Higgs model ins the latticer is investigated using analytic and numerical methods. The technique of monopole suppression is used to determine the phase transition lines that are monopole driven. Finally in chapter VII, the role of the charge of the Higgs field in the abelian Higgs model in the lattice is investigated

  18. Topics in inflationary cosmology

    International Nuclear Information System (INIS)

    Kahn, R.N.

    1985-01-01

    This thesis examines several topics in the theory of inflationary cosmology. It first proves the existence of Hawking Radiation during the slow-rolling period of a new inflationary universe. It then derives and somewhat extends Bardeen's gauge invariant formalism for calculating the growth of linear gravitational perturbations in a Friedmann-Robertson-Walker cosmological background. This formalism is then applied, first to several new inflationary universe models all of which show a Zel'dovich spectrum of fluctuations, but with amplitude sigma(100 4 ) above observational limits. The general formalism is next applied to models that exhibit primordial inflation. Fluctuations in these models also exhibit a Zel'dovich spectrum here with an acceptable amplitude. Finally the thesis presents the results of new, numerical calculations. A classical, (2 + 1) dimensional computer model is developed that includes a Higgs field (which drives inflation) along with enough auxiliary fields to generate dynamically not only a thermal bath, but also the fluctuations that naturally accompany that bath. The thesis ends with a discussion of future prospects

    The Accellera Universal Verification Methodology (UVM) standard is architected to scale, but verification is growing and in more than just the digital design dimension. It is growing in the SoC dimension to include low-power and mixed-signal and the system integration dimension to include multi-language support and acceleration. These items and others all contribute to the quality of the SOC so the Metric-Driven Verification (MDV) methodology is needed to unify it all into a coherent verification plan. This book is for verification engineers and managers familiar with the UVM and the benefits it brings to digital verification but who also need to tackle specialized tasks. It is also written for the SoC project manager that is tasked with building an efficient worldwide team. While the task continues to become more complex, Advanced Verification Topics describes methodologies outside of the Accellera UVM standard, but that build on it, to provide a way for SoC teams to stay productive and profitable.

    Cellulite is a common topographical alteration where skin acquires an orange peel or mattress appearance with alterations in adipose tissue and microcirculation. This work aims to develop and evaluate a topical niosomal gel formulae with good permeation to reach the subcutaneous fat layer. Several caffeine niosomal dispersions were prepared and incorporated into gel formulae using Carbopol 940 polymer, chemical penetration enhancers, and iontophoresis, then the prepared gels were applied onto the skin of rats and anticellulite activity of caffeine from the prepared gels compared to that of the commercial product Cellu Destock ® was evaluated by histological study of the skin and measurement of plasma level of caffeine passing through the skin using liquid chromatography (LC/MS-MS). Results of histology revealed reduction of size and thickness of fatty layer of rat skin in the following order: FVII > FXIV > Cellu Destock ®  > FVII + Iontophoresis > FXIV + Iontophoresis. Pharmacokinetic results of caffeine in plasma revealed that C max , T max , and AUC 0-12h decreased in the following order: FXIV > FVII > Cellu Destock ® . These results conclude that incorporation of caffeine niosomal dispersion into gel matrix with penetration enhancers and iontophoresis resulted in improvement in penetration of caffeine through the skin into the underlying fatty layer in treatment of cellulite.

    Full Text Available To explore the effects and mechanisms of Xiaozheng Zhitong Paste (XZP on bone cancer pain, Wistar rats were inoculated with vehicle or prostate cancer PC-3 into the tibia bone and treated topically with inert paste, XZP at 15.75, 31.5, or 63 g/kg twice per day for 21 days. Their bone structural damage, nociceptive behaviors, bone osteoclast and osteoblast activity, and the levels of OPG, RANL, RNAK, PTHrP, IGF-1, M-CSF, IL-8, and TNF-α were examined. In comparison with that in the placebo group, significantly reduced numbers of invaded cancer cells, decreased levels of bone damage and mechanical threshold and paw withdrawal latency, lower levels of serum TRACP5b, ICTP, PINP, and BAP, and less levels of bone osteoblast and osteoclast activity were detected in the XZP-treated rats (P<0.05. Moreover, significantly increased levels of bone OPG but significantly decreased levels of RANL, RNAK, PTHrP, IGF-1, M-CSF, IL-8, and TNF-α were detected in the XZP-treated rats (P<0.05 for all. Together, XZP treatment significantly mitigated the cancer-induced bone damage and bone osteoclast and osteoblast activity and alleviated prostate cancer-induced bone pain by modulating the RANKL/RANK/OPG pathway and bone cancer-related inflammation in rats.

    The human risk of harmful substances in semisolid topical dosage forms applied topically to normal skin and broken skin, respectively, was assessed. Bisphenol A diglycidyl ether (BADGE) and three derivatives of BADGE previously quantified in aqueous cream and the UV filters 3-BC and 4-MBC were used...... as model compounds. Tolerable daily intake (TDI) values have been established for BADGE and derivatives. Endocrine disruption was chosen as endpoint for 3-BC and 4-MBC. Skin permeation of the model compounds was investigated in vitro using pig skin membranes. Tape stripping was applied to simulate broken...... parameters for estimating the risk. The immediate human risk of BADGE and derivatives in topical dosage forms was found to be low. However, local treatment of broken skin may lead to higher exposure of BADGE and derivatives compared to application to normal skin. 3-BC permeated skin at higher flux than 4-MBC...

    Leenen, F H; Smith, D L; Unger, W P

    1988-01-01

    Systemic cardiovascular effects during chronic treatment with topical minoxidil vs placebo were evaluated using a double-blind, randomized design for two parallel groups (n = 20 for minoxidil, n = 15 for placebo). During 6 months of follow-up, blood pressure did not change, whereas minoxidil increased heart rate by 3-5 beats min-1. Compared with placebo, topical minoxidil caused significant increases in LV end-diastolic volume, in cardiac output (by 0.751 min-1) and in LV mass (by 5 g m-2). We conclude that in healthy subjects short-term use of topical minoxidil is likely not to be detrimental. However, safety needs to be established
