Hanna Bergman, Dawn-Marie Walker, Adriani Nikolakopoulou, Karla Soares-Weiser, Clive E Adams
BACKGROUND: Antipsychotic medication can cause tardive dyskinesia (TD) - late-onset, involuntary, repetitive movements, often involving the face and tongue. TD occurs in > 20% of adults taking antipsychotic medication (first-generation antipsychotics for > 3 months), with this proportion increasing by 5% per year among those who continue to use these drugs. The incidence of TD among those taking newer antipsychotics is not different from the rate in people who have used older-generation drugs in moderate doses...

REVIEW
M Rudwaleit, K Walscheid, A Heiligenhaus
Acute anterior uveitis (AAU) is the most frequent uveitis subtype. It is often associated with HLA-B27 and with inflammatory rheumatic diseases, in particular with spondyloarthritis (SpA), which itself is strongly associated with HLA-B27. About 40-60% of patients with AAU have an associated spondyloarthritis, and 20-40% of patients with spondyloarthritis also have uveitis. The incidence of AAU in patients with SpA clearly correlates with disease duration. The AAU has an acute onset, usually affects only one eye at a time, and shows a tendency for recurrence...

BACKGROUND: Uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis (JIA). It occurs, according to German registry data, in around 12% of JIA patients and can lead to a loss of vision, especially in cases of delayed diagnosis and/or inadequate therapy. OBJECTIVE: A review of current aspects of diagnosis and therapy was carried out. MATERIAL AND METHODS: This is a review article of the current literature. RESULTS: The risk of uveitis is significantly elevated in patients with an oligoarticular course of JIA, ANA positivity and young age at onset of JIA...

Nonporous silica nanoparticles (SiNPs) have potential as promising carriers for ophthalmic drugs. However, the in vivo safety of ocular topical SiNPs remains unclear. This study investigated the in vivo safety of oral and ocular topical applications of 100 nm-sized SiNPs in Sprague-Dawley rats. The rats were divided into the following four groups: low-dose oral administration (total 100 mg/kg of SiNPs mixed with food for one week), high-dose oral administration (total 1000 mg/kg of SiNPs mixed with food for one week), ocular topical administration (10 mg/ml concentration, one drop, applied to the right eyes four times a day for one month), or a negative control (no SiNP treatment)...

Sandra A G Visser, Tjerk J H Bueters
In 2005, Danhof and coauthors proposed a new biomarker classification in the context of the application of mechanism-based PKPD modeling. They defined the term 'biomarker' as a measure that characterizes a drug-induced response, which is on the causal path between drug administration and clinical outcome. The biomarker classification identified seven categories that provide different insights into the kinetics of drug action, such as target site distribution, target engagement, or into the impact of the drug on physiology or disease...

Alexandra Rosenberg, Jon Meyerle
Psoriasis is a chronic immune-mediated dermatologic disorder affecting approximately 2% of the general population. Under current U.S. Army regulation, the diagnosis of psoriasis is a bar to enlistment or appointment and, if poorly controlled, is grounds for referral to a Medical Evaluation Board and potential discharge from military service, according to Army Regulation 40-501. However, between 2008 and 2015, over 3,600 soldiers sought care for psoriasis while deployed to combat theaters, indicating that psoriasis remains a significant medical concern in the U...

<p>There is compelling evidence that Infrared A (IRA) from natural sunlight contributes to photoaging of human skin by inducing the expression of matrix metalloproteinase-1 (MMP-1) expression in human dermal fibroblasts. Corresponding mechanistic studies have shown that IRA does so by increasing the production of reactive oxygen species in irradiated cells. In the present study, we therefore asked if treatment of primary human skin fibroblasts with a blueberry-derived antioxidant matrix (BerrimatrixTM), which is employed as an active ingredient in commercially available skin care products that are topically applied, can prevent IRA-induced MMP-1 expression in these cells...

<p>INTRODUCTION: Many options are available for patients with moderate to severe plaque psoriasis. Patients with moderate disease, however, are often undertreated and do not achieve satisfactory clearance. UNVEIL (NCT02425826) assessed efficacy and safety of apremilast in patients with chronic moderate plaque psoriasis.</p> <p>METHODS: Patients with psoriasis body surface area (BSA) 5% to 10% and static Physician's Global Assessment (sPGA) score of 3 (moderate) without prior exposure to systemics were randomized (2:1) to apremilast 30 mg twice daily or placebo for 16 weeks...

<p>Inverse or intertriginous psoriasis commonly involves skin fold areas including the axillae, perianal skin, intergluteal cleft, inframammary, genital/inguinal, abdominal, and retroauricular folds. After reviewing the literature for new treatments, a task force was convened to update a consensus on inverse psoriasis therapy. Short-term treatment continues to be low-potency topical steroids. In order to avoid steroid-induced adverse effects, long-term therapy includes topical immunomodulators, calcitriol, and calcipotriene...

<p>BACKGROUND: Topical corticosteroids are the most common dermatologic medications and are available in numerous different vehicles. Adherence is limited by traditional vehicles because they are messy and time consuming to apply. The preferred spray formulations have the advantage of being applied with ease, resulting in improved adherence and subsequently improved psoriasis. One limitation of topical treatments, especially spray vehicles, is the potential for irritation and sensitization.</p> <p>OBJECTIVE: To evaluate the irritation and sensitization potential of topical desoximetasone spray formulation...

<p>BACKGROUND: Topical corticosteroids are known to impair the epidermal barrier, even after short-term use, whereas topical vitamin D analogues can have a reparative effect. Combination products using corticosteroids and vitamin D analogues have gained popularity in recent years and may provide a means to minimize skin atrophy in patients treated with topical corticosteroids.</p> <p>OBJECTIVE: To compare epidermal barrier function and cutaneous atrophy after 4 weeks of calcipotriene 0.005% and betamethasone dipropionate 0...

Catechin is found in several natural sources, as Eugenia dysenterica and Syzygium cumini extracts. Its antioxidant and UV-protective properties suggest a potential use in cosmetic and dermatological formulations. A simple analytical method capable of giving support to experiments performed along the development of topical formulations containing this natural substance (i.e., drug assay, skin permeation and stability studies), however, is still demanded. Thus, this work aimed to develop and validate a selective HPLC method for catechin determination during the development of topical formulations...

HYPOTHESIS: Microemulsion-based semisolid systems may be considered as an interesting alternative to the traditional dosage forms applied in topical drug delivery. Mechanical properties of topical products are important both in terms of application and dosage form effectiveness. In this study we designed and evaluated novel microemulsion-based gels with indomethacin and analyzed the factors affecting their mechanical characteristics and drug release. EXPERIMENTS: The impact of the microemulsion composition on the extent of isotropic region was investigated with the use of pseudoternary phase diagrams...

RATIONAL: The inhibition of renin-angiotensin-aldosterone system (RAAS) is a major strategy for slowing the progression of chronic kidney disease (CKD). The utility of anti-RAAS agents in patients with congenital or acquired solitary kidney is still controversial. OBJECTIVE: A systematic literature review was conducted. MAIN FINDINGS: The conclusions of the few available studies on the topic are homogeneously in agreement with a long-term reno-protective activity of anti-RAAS drugs in patients with solitary kidney, especially if patients are hypertensive or proteinuric...

Platelet-Rich Plasma (PRP) is an autologous biological therapy obtained by centrifuging the patient's own blood to concentrate platelets. The addition of autologous thrombin and calcium chloride to PRP allows the production of a semi-solid form called PRP gel. PRP gel is increasingly used in a variety of tissue defects and predominantly in the management of non-healing chronic wounds. The topical application of PRP gel seems promising due to the capability of platelets to store and secrete growth factors (GF), fibrin and cytokines, which are essentials for wound healing...

Surfactant-free biocompatible and biodegradable Pickering emulsions were investigated as vehicles for skin delivery of hydrophobic drugs. O/w emulsions of medium-chain triglyceride (MCT) oil droplets loaded with all-trans retinol as a model hydrophobic drug were stabilized by block copolymer nanoparticles: either poly(lactide)-block-poly(ethylene glycol) (PLA-b-PEG) or poly(caprolactone)-block-poly(ethylene glycol) (PCL-b-PEG). Those innovative emulsions were prepared using two different processes allowing drug loading either inside oil droplets or inside both oil droplets and non-adsorbed block copolymer nanoparticles...
