Eruptive Epidermoid Cysts Resulting from Treatment with Imiquimod

Chelsy L. Marty MD
Background Because of its unique mechanism of action and safety profile, imiquimod, a topical immune response modifier, is used for many benign and malignant dermatologic conditions. Adverse effects are typically limited to treatment site erythema and erosion. Objective To describe a newly recognized adverse effect of imiquimod. Methods A 79-year-old woman being treated with imiquimod 5 days per week for a nodular basal cell developed a verrucous plaque over the treatment area after 7 weeks of therapy. Results Scouting biopsies demonstrated multiple comedones and ruptured epidermoid cysts. There was no evidence of residual basal cell carcinoma. Conclusions Imiquimod is a new and novel treatment option for cutaneous malignancies. We report its successful use in the treatment of a nodular basal cell carcinoma. The multiple comedones and ruptured epidermoid cysts are newly reported adverse effects of imiquimod therapy. [source]

Acetylcholinesterase treatment,modelling potential demand and auditing practice

Simon Lovestone
Abstract Background Acetylcholinesterase inhibitors represent an entirely novel treatment option for patients with Alzheimer's disease (AD). As such they represent a significant change in practice and a significant cost pressure on funding bodies. Objectives To assess the impact of cholinesterase inhibitors on routine clinical practice. Methods We estimated potential demand for the compounds taking into account eligibility criteria and prescribing practice agreed between clinicians and funders. We then audited actual prescribing practice assessing whether the estimated demand matched actual demand and whether practice and prescribing criteria were adhered to. Results Over a two-year period we estimated the demand for treatment at a total of 89 patient years for the population of the audit unit. In practice only 24.5 patient years of therapy were received, the short fall apparently being due to low referral rates for treatment. Prescribing by clinicians matched practice guidelines and a high proportion of three monthly assessments using scales for cognition, function and global state were performed. Using these assessment procedures treatment successes could be differentiated from primary and secondary treatment failures and, where apparently appropriate, treatment could be stopped. Conclusion In the real world of clinical practice demand for treatment in AD is modest but likely to grow and assessment with an aim to identifying those receiving benefit from treatment can be achieved.

Acotiamide (Z-338) as a possible candidate for the treatment of functional dyspepsia

H. Suzuki
Abstract Acotiamide hydrochloride is a novel upper gastrointestinal (GI) motility modulator and stress regulator currently being developed for the treatment of functional dyspepsia (FD). The mechanism underlying the enhancement of GI motility by this agent has been proposed to be based on its muscarinic antagonism and inhibitory effects on acetylcholinesterase activity. Pathophysiological studies showed that acotiamide significantly improved both delayed gastric emptying and feeding inhibition in restraint stress-induced model, but did not affect both normal gastric emptying and feeding in intact animals, indicating that acotiamide exerted effects only on the impaired gastric emptying and feeding behavior. According to the clinical pilot study in Europe, acotiamide, at the dose of 100 mg t.i.d., showed to improve the symptoms and quality of life of patients with FD, indicating the need for larger scale symptomatic studies on the efficacy of acotiamide in patients with FD. The recent phase II studies conducted in Japan presented in this issue of the journal also confirmed that acotiamide, at the optimal dose of 100 mg, has potential therapeutic efficacy, especially for meal-related FD symptoms. Although a phase III study is on going, acotiamide is now expected as a novel treatment option for FD. [source]

A Novel Drug Therapy for Recurrent Laryngeal Nerve Injury Using T-588,

Yuko Mori MD
Abstract Objectives/Hypothesis: We have previously shown that gene therapy using Insulin-like growth factor (IGF)-I, glial cell line-derived neurotrophic factor (GDNF), and brain-derived neurotrophic factor (BDNF), or a combination of these trophic factors, is a treatment option for recurrent laryngeal nerve (RLN) palsy. However, there remain some difficulties preventing this option from becoming a common clinical therapy for RLN injury. Thus, we need to develop novel treatment option that overcomes the problems of gene therapy. R(,)-1-(benzothiophen-5-yl)-2-[2-N,N-diethylamino]ethoxy]ethanol hydrochloride (T-588), a synthetic compound, is known to have neuroprotective effects on neural cells. In the present study, the possibility of new drug treatments using T-588 for RLN injury was assessed using rat models. Study Design: Animal study. Methods: Animals were administered T-588 for 4 weeks. The neuroprotective effects of T-588 administration after vagal nerve avulsion and neurofunctional recovery after recurrent laryngeal nerve crush were studied using motoneuron cell counting, evaluation of choline acetyltransferase immunoreactivity, the electrophysiologic examination, and the re-mobilization of the vocal fold. Results: T-588 administration successfully prevented motoneuron loss and ameliorated the choline acetyltransferase immunoreactivity in the ipsilateral nucleus ambiguus after vagal nerve avulsion. Significant improvements of motor nerve conduction velocity of the RLN and vocal fold movement were observed in the treatment group when compared to controls. Conclusion: These results indicate that oral administration of T-588 might be a promising therapeutic option in treating peripheral nerve injury. [source]

Atrial fibrillation: insights from clinical trials and novel treatment options

Y. Blaauw
Abstract., Blaauw Y, Crijns HJGM (University Hospital Maastricht, Maastricht, The Netherlands). Atrial fibrillation: insights from clinical trials and novel treatment options (Review). J Intern Med 2007; 262: 593,614. Atrial fibrillation (AF) is the most common encountered sustained arrhythmia in clinical practice. The last decade the result of large ,rate' versus ,rhythm' control trials have been published that have changed the current day practise of AF treatment. It has become clear that rate control is at least equally effective as a rhythm control strategy in ameliorating morbidity as well as mortality. Moreover, in each individual patient the risk of thromboembolic events should be assessed and antithrombotic treatment be initiated. There have also been great advances in understanding the mechanisms of AF. Experimental studies showed that as a result of electrical and structural remodelling of the atria, ,AF begets AF'. Pharmacological prevention of atrial electrical remodelling has been troublesome, but it seems that blockers of the renin angiotensin system, and perhaps statins, may reduce atrial structural remodelling by preventing atrial fibrosis. Clinical studies demonstrated that the pulmonary veins exhibit foci that can act as initiator and perpetuator of the arrhythmia. Isolation of the pulmonary veins using radiofrequency catheter ablation usually abolishes AF. The most promising advances in the pharmacological treatment of AF include atrial specific antiarrhythmic drugs and direct thrombin inhibitors. In the present review we will describe the results of recent experimental studies, discuss the latest clinical trials, and we will focus on novel treatment modalities. [source]

Review article: the current and evolving treatment of colonic diverticular disease

Summary Background, Formation of colonic diverticula, via herniation of the colonic wall, is responsible for the development of diverticulosis and consequently diverticular disease. Diverticular disease can be associated with numerous debilitating abdominal and gastrointestinal symptoms (including pain, bloating, nausea, constipation and diarrhoea). Aims, To review the state of treatment for diverticular disease and its complications, and briefly discuss potential future therapies. Methods, PubMed and recent conference abstracts were searched for articles describing the treatment of diverticular disease. Results, Many physicians will recommend alterations to lifestyle and increasing fibre consumption. Empirical antibiotics remain the mainstay of therapy for patients with diverticular disease and rifaximin seems to be the best choice. In severe or relapsing disease, surgical intervention is often the only remaining treatment option. Although novel treatment options are yet to become available, the addition of therapies based on mesalazine (mesalamine) and probiotics may enhance treatment efficacy. Conclusions, Data suggest that diverticular disease may share many of the hallmarks of other, better-characterized inflammatory bowel diseases; however, treatment options for patients with diverticular disease are scarce, revolving around antibiotic treatment and surgery. There is a need for a better understanding of the fundamental mechanisms of diverticular disease to design treatment regimens accordingly. [source]

Optimization of Thienopyrrole-Based Finger-Loop Inhibitors of the Hepatitis,C Virus NS5B Polymerase

CHEMMEDCHEM, Issue 10 2009
Hernando Dr., Ignacio Martin
Abstract Infections caused by the hepatitis,C virus (HCV) are a significant world health problem for which novel therapies are in urgent demand. The NS5B polymerase of HCV is responsible for the replication of viral RNA and has been a prime target in the search for novel treatment options. We had discovered allosteric finger-loop inhibitors based on a thieno[3,2- b]pyrrole scaffold as an alternative to the related indole inhibitors. Optimization of the thienopyrrole series led to several N -acetamides with submicromolar potency in the cell-based replicon assay, but they lacked oral bioavailability in rats. By linking the N4-position to the ortho -position of the C5-aryl group, we were able to identify the tetracyclic thienopyrrole 40, which displayed a favorable pharmacokinetic profile in rats and dogs and is equipotent with recently disclosed finger-loop inhibitors based on an indole scaffold.
