Preparation and Evaluation of Itraconazole Nanoparticle Lipid Carrier Gel for Dermatophytosis

Fungal infection is one of the common dermatological diseases. Drug delivery systems for topical use have shown significant advantages in targeting the drug to the action site in the body and also reduces the systemic side effects. Itraconazole was chosen as a model drug with low aqueous solubility. In the present study an attempt was made to prepare itraconazole loaded nanostructured lipid carrier (NLC). Different formulations were prepared by hot homogenization technique using solid lipid and liquid lipid (Compritol 888 & Caprol PGE 860) and surfactants (Poloxamer 188, tween 80). All the Formulations were characterized for drug content, entrapment efficiency, particle size, poly dispersity index, zeta potential &in vitro drug release and FTIR was done to study any interaction between excipients. The best formulation shows better drug release and entrapment efficiency 83.2%. the best formulation F3 showed better in-vitro drug release 55.46% at the end of 8th hour. The F3 was made into gel using Carbopol as a gelling agent. SEM study revealed that the NLC gel shows the particle size was found to be 500 nm in size smooth surfaces. NLC gel shows Drug release of NLC gel followed non- Fickian diffusion. NLC gel were stable at 40 ± 2ֹ°C and 75 ± 5% RH. Thus, the prepared NLC gel proved to be a potential candidate as a topical nanoparticulate sustained drug delivery system for itraconazole (BCS class II drug). keywords: Itraconazole, Nanoparticle Lipid Carrier, Lipids.

Rehabilitation of patients with vulvovaginal atrophy

Background. Genitourinary syndrome of menopause (GSM) is characterized by a number of pathological changes, in particular urological disorders, vulvovaginal atrophy (VVA) and sexual dysfunction. They are commonly accompanied by decreased quality of life (QoL) and often require medical intervention. At the same time, the steps taken to effectively solve this problem are not enough. Thus, it seems relevant to search for rehabilitation methods for VVA patients.Objective: to determine the effectiveness of current rehabilitation methods for VVA patients.Material and methods. The search of publications in international scientific databases PubMed/MEDLINE, ScienceDirect, search engines and eLibrary revealed 4,330 publications, of them 44 sources were selected for the analysis after the screening procedure according to PRISMA scheme.Results. VVA is based on decreased serum estrogen level and estrogen receptors quantity. Estrogen is a vasoactive hormone that promotes blood supply to the genitals and is involved in maintaining the normal genitourinary microflora. This may occur in women for age-related reasons or as a result of ongoing therapy or radical surgical intervention. At the same time, GSM is often formed, where VVA is one of the key elements. These changes are accompanied by sexual dysfunction, distress and decreased overall QoL in women. It is advisable to carry out complex personalized rehabilitation and QoL monitoring for such patients. The effectiveness of estrogen-containing therapy for topical use as well as adjunctive therapy with non-hormonal lubricants and moisturizing gels or creams was shown for VVA patients.Conclusion. It was determined that VVA symptoms, in general, significantly affect the patients’ QoL, regardless of age. The necessity of developing specialized rehabilitation programs conducted by specialists of various profiles was noted. The effectiveness of these programs will be higher with timely diagnosis, which also requires significant attention.

Recurrence following ptosis repair surgery: a multivariate analysis of risk factors

ABSTRACT Purpose To identify and evaluate the risk factors for ptosis repair failure. Methods Retrospective, case-controlled study evaluating adult patients with ptosis who underwent ptosis surgery by external levator advancement/resection (ELR) or Müller muscle conjunctival resection (MMCR) with at least 3 months postoperative follow-up. Regression analyses were performed of ptosis repair outcomes comparing preoperative and perioperative risk factors for failure. Results A total of 240 patients (404 eyelids) met the inclusion criteria for the study. Surgical outcomes were measured categorically by success rate and measured quantitively over time using Kaplan–Meier survival analysis. Success was categorically achieved in 101/112 (90%) eyelids after MMCR and 231/292 (79%) eyelids after ELR (p = .0088). Success as measured over 5 years of follow-up was significantly better in eyelids following MMCR compared to ELR (p = .0469). In terms of surgical failure, the following variables were found to be predictive in order of decreasing risk: chronic topical prostaglandin use, chronic topical corticosteroid use, surgical approach, lower preoperative margin reflex distance 1, prior intraocular surgery, age, lower preoperative levator function, concomitant blepharoplasty, presence of a glaucoma filtering bleb, and female gender. Conclusions Ptosis repair surgery is a complex and challenging procedure. This study provides the largest comparative analysis of ELR versus MMCR to date with findings suggesting MMCR to be more a successful surgery than ELR. Topical prostaglandin analogue use appears to be the highest known risk factor for MMCR and ELR ptosis repair failure.

Patterns and Motivations of Topical Steroid Use for Skin Whitening in Jazan, Saudi Arabia: A Cross-Sectional Survey.

Background The use of topical steroids for skin whitening is prevalent in many regions, including Saudi Arabia. This study aims to analyze the patterns, motivations, and demographic factors associated with the use of topical steroids for cosmetic purposes in Jazan, Saudi Arabia. Methods This cross-sectional survey was conducted online over three weeks. A structured questionnaire was distributed to adults residing in Jazan, collecting data on demographics, topical steroid use, motivations, and product sources. Descriptive statistics were used to analyze the data. Results Among the 340 participants, 173 (50.9%) reported using topical steroids for skin whitening. The majority of users were female (149, 43.8%) and aged between 20 and 30 years (78, 22.9%). Most participants had used topical steroids for less than a year (127, 73.4%), with usage predominantly in the evening (86, 49.7%). Topical steroids were primarily purchased from pharmacies (70, 40.5%), with significant monthly expenditure variability: 55 participants (31.8%) spent between 50 and 110 SAR, and 62 (35.7%) spent more than 150 SAR. Motivations for use included a preference for lighter skin (49, 28.4%) and treatment of melasma (42, 24.3%). Recommendations from friends (71, 41.0%) and TV advertisements (34, 19.8%) influenced product choice. Conclusion Topical steroid use for skin whitening is widespread among adults in Jazan, with a notable emphasis on cosmetic outcomes and substantial financial investment. There is a critical need for increased public education on the risks associated with topical steroids and enhanced professional guidance to promote safer usage practices.

Multiple Anterior Chamber Paracenteses May Be Needed to Identify Cytomegalovirus Anterior Uveitis

PURPOSETo demonstrate cases of anterior uveitis requiring more than one anterior chamber paracenesis to elucidate CMV as the causative etiology. DESIGNRetrospective chart review. METHODSPatients were seen at the Francis I. Proctor Foundation at the University of California, San Francisco between 2013 to 2024. Patients who required more than one anterior chamber paracentesis to detect CMV as the etiologic agent of their anterior uveitis were included. Number of anterior chamber paracenteses required to detect CMV, demographic and clinical features, viral load at time of positive anterior chamber paracentesis and association between topical corticosteroid use and viral load at time of positive anterior chamber paracentesis. RESULTSFourteen patients required a median of 2 (range 2-4) anterior chamber paracenteses to detect CMV. Mean age was 48.2 years, and 57.1% were male. Most patients (64.3%) were born in East and Southeast Asia. All affected eyes featured ocular hypertension. Five patients (35.7%) were initially treated with systemic immunosuppression before CMV was detected. Increasing frequency of topical corticosteroid use was significantly associated with higher CMV viral loads (p<0.001). Five patients (35.7%) required glaucoma surgery. In 13 patients with available data, uveitis was present for an average of 2776 days (range 23-7889 days) prior to CMV detection. Once diagnosed, most patients were treated with oral valganciclovir, with one patient transitioning to letermovir due to side effects. CONCLUSIONSCMV anterior uveitis may be more prevalent than previously recognized and often requires multiple anterior chamber paracenteses for diagnosis. Reliance on a signle negative test may lead to misdiagnosis and inappropriate treatment. Clinicians should maintain a high index of suspicion for CMV in cases of recurrent anterior uveitis, particularly in patients of East and Southeast Asian descent. This study highlights the importance of repeated testing and appropriate antiviral treatment to prevent complications such as glaucoma.

Optimized production of carboxymethyl cellulose/guar gum based durable hydrogel for in vitro performance assessment

An important objective of researchers is to develop a perfect wound dressing that can effectively treat different kinds of wounds. Natural substances with beneficial qualities, such as plant extracts and biopolymers are an ideal aid for wound care. Hydrogels based on biopolymers offer a lot of promising applications for topical use and are biocompatible, hydrophilic and non-toxic. When employed alone or in conjunction with other active agents, herbal extracts have a great deal of use in the healing of wounds. This study comprises Ruellia tuberosa extract loaded with carboxymethyl cellulose and guar gum hydrogels that have potential anti-bacterial, antioxidant, anti-inflammatory and hemocompatibility. Using mouse fibroblast cells (L929), the MTT (3- (4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) test was conducted to assess the biocompatibility. Furthermore, the scratch wound assay using the L929 fibroblast cell line of mouse was employed to assess the in vitro wound healing potential of the synthesised composite hydrogels.

Trinitroglycerin-loaded chitosan nanogels accelerate angiogenesis in wound healing process

Trinitroglycerin (TNG) with remarkable angiogenic, antibacterial, and antioxidative activity is a promising candidate to govern wound healing capacity. However, its clinical administration is limited due to associated complications and NO short half-life. In the current study, TNG-loaded chitosan nanogels (TNG-Ngs) were examined in-vitro and in-vivo to gain insight into their clinical application. We prepared TNG-Ngs and characterized their physiochemical properties. The potential of TNG-Ngs was assessed using biocompatibility, scratch assay, and a full-thickness skin wounds model, followed by histopathological and immunohistochemistry examinations. TNG-Ngs particle size 96 ± 18 and definite size distribution histogram. The loading capacity (LC) and encapsulation efficiency (EE) of prepared TNG-Ngs were 70.2 % and 2.1 %, respectively. The TNG-Ngs samples showed enhanced migration of HUVECs with no apparent cytotoxicity. The topical use of TNG-Ngs200 on the wounds revealed a complete wound closure ratio, skin component formation, less scar width, remarkable granulation tissue, promoted collagen deposition, and enhanced the relative mean density of α-SMA and CD31. TNG-Ngs accelerated wound healing by promoting collagen deposition and angiogenic activity, as well as reducing inflammation. The findings indicated that TNG-Ngs is expected to be well vascularized in the wound area and to be more effective in topical therapy.

Capturing and reporting topical treatment use in childhood eczema: lessons for data collection in eczema trials.

Emollients and topical corticosteroids (TCS) prevent and treat flares in eczema. However, topical treatment use is poorly recorded and reported in clinical trials. There is no clear consensus of how best to capture and summarise topical treatment use. To explore different ways of capturing and reporting topical treatment use in childhood eczema. Secondary data analysis using 450 participants from the Best Emollients for Eczema (BEE) trial. Participants were allocated to use one type of emollient (lotion, cream, gel, or ointment) 'twice daily and when required' for 16 weeks. Otherwise, clinical management remained unchanged. Parents completed weekly questions about topical therapy use and eczema symptoms. Two versions of topical treatment use questionnaires were used. The first (n=202, 44.9%) asked parents to report treatment use on days 1-7, starting completion on the day they were randomised. The second (n=248, 55.1%) reported use by day of the week (Monday to Sunday), starting completion the first Monday after randomisation. Both underwent Patient and Public Involvement (PPI) review, but the second version was tested more thoroughly using cognitive interviewing techniques, following parent feedback that questions on the first version were confusing. Descriptive statistics compared questionnaire completion and differences in emollient and TCS use. Overall, questionnaire completion for both emollient and TCS use decreased with time: but at weeks 1 and 16 were 84.7% (381/450) and 58.9% (265/450) for emollient use, and 94.2% (424/450) and 80.4% (362/450) for TCS use, respectively. Fewer emollient use questionnaires were completed with first (33.5%) than the second (87.9%) version (p<0.001). TCS use questionnaire completion were similar for both (84.9% and 87.4%, p=0.002). We present different ways of summarising topical treatment use. While questionnaire completion was similar for TCS use, emollient use data completeness was higher in the second version. When designing questionnaires, balancing the detail and complexity of questions is important, especially if being collected as a secondary outcome measure. Numerous ways of summarising the same data can provide different information. Future collection and reporting of treatment use should reflect specific trial aims.

Progression Patterns and Risk Factors of Axial Elongation in Young Adults With Nonpathologic High Myopia: Three-Year Large Longitudinal Cohort Follow-Up

To investigate the progression patterns and risk factors of axial elongation in young adults with nonpathologic high myopia. Prospective, clinical observational cohort study with 2- to 4-year follow-up. A total of 1043 eyes of 563 participants (3515 medical records) aged 18 to 50 years with nonpathologic high myopia (axial length [AL] ≥ 26 mm; myopic maculopathy < diffuse chorioretinal atrophy; without posterior staphyloma) were included from 1546 participants (6318 medical records). Annual axial elongation was calculated via linear mixed-effect models. The associated risk factors of axial elongation were determined by ordinal logistic regression analysis, with generalized estimate equations for eliminating an interocular correlation bias. Based on 5359 times of AL measurements, the annual axial elongation of participants (mean [SD] age 31.39 [9.22] years) was 0.03 mm/year (95% confidence interval [CI], 0.03-0.04; P < .001) during a 30.23 (6.06) months' follow-up. Severe (>0.1 mm/year), moderate (0.05-0.09 mm/year), mild (0-0.049 mm/year), and nil (≤0 mm/year) elongation was observed in 122 (11.7%), 211 (20.2%), 417 (40.0%), and 293 (28.1%) eyes. The following risk factors were significantly associated with axial elongation: baseline AL ≥ 28 mm (odds ratio [OR], 4.23; 95% CI, 2.95-6.06; P < .001); age < 40 years (OR, 1.64; 95% CI, 1.18-2.28; P = .003); axial asymmetry (OR, 2.04; 95% CI, 1.26-3.29; P = .003), and women (OR, 1.52; 95% CI, 1.13-2.2.05; P = .006). Using antiglaucoma medications was a protective factor (OR, 0.46; 95% CI, 0.27-0.79; P = .005), which slowed 75% of axial elongation from 0.04 (0.06) to 0.01 (0.06) mm/y (P < .001). Axial elongation continued in young adults with nonpathologic myopia. Risk factors included longer baseline AL and axial asymmetry, younger age, and woman. Topical use of antiglaucoma medications may be useful to reduce ongoing axial elongation.

Sustainability Aspects of Carapa Guianensis Aubl Oil for Antiinflammatory Uses

Objective: The objective of this study is to describe the lipidomic profile of andiroba oil and its socio-economic characteristics focused on the activities of limonoids as an alternative for the generation of nonsteroidal anti- inflammatory drugs in order to relate the generation of products that act on circular and external peripheral inflammation. Theoretical Reference: In this context, andiroba oil (C. guianensis) has a wealth of lipid substances with chemical and socio-economic potential, highlighting its importance for local populations and its potential for sustainable bioeconomics, as this species contains nonsteroidal antiinflammatory drugs from Amazonian oil plants. Method: The methodology adopted includes describing the lipidomic profile of andiroba oil analyzed by GC/MS, using a Zebrom 5HT capillary column specifically designed to analyze both the methyl esters of the various fatty acids and the limonoids and steroids. The bibliographic search was carried out in the CAPES periodicals on the Scopus database, using specific keywords such as andiroba, Carapa, limonoids and antiinflammatories. Three samples of andiroba oil collected in different states were used to compare the lipidomic profiles. Results and Discussion: The results obtained revealed the presence of limonoids 7-desacetyl-7-oxogedunin, 7- oxogedunin, deacetyl gedunin; steroids campesterol, stigmasterol, b-sitosterol and various medium and long chain fatty acids. These results showed valuable information about the presence of limonoids, which have anti-inflammatory properties related to the chemical composition, which can vary with the season, the place of collection and the differences in the extraction processes of this oil. However, there is no total absence of limonoids. Research Implications: This research's practical and theoretical implications emphasize that the active anti-inflammatory principles are found in the unsaponifiable fraction, and therefore, only lipidomic techniques can access these metabolites with more excellent resolution. Thus, with the structural identifications, in silico studies can be carried out to classify their effects on cyclooxygenase enzymes (COXs), specifically COX-1, in circular and external peripheral inflammation. Originality/Value: This study contributes to the literature through the perspective of developing safe anti- inflammatory agents produced from andiroba oil, which is a source of great interest for topical use. This oil stands out as one of the most scientifically studied natural products, being biocompatible and presenting itself as an economical and safe alternative for treating circular and external peripheral inflammations. The relevance and value of this research is evidenced by the fact that limonoids are inhibitors of cyclooxygenases, highlighting the prospect of a new socio-economic aspect.

From beverage to anticancer agent: The repurposing of green coffee bean extract loaded in solid lipid nanoparticles

Green coffee bean extract (GCBE) captivated the world with its various health benefits. However, its topical use was limited by the hampered penetration of hydrophilic GCBE through the skin. So, this study aimed to incorporate GCBE-loaded solid lipid nanoparticles (SLNs) into water-in-oil (W/O) cream, to explore its repurposed application as an anticancer drug. The anticancer activity was assessed in vitro using MTT assay against human breast cancer cell lines (MCF-7) and in vivo using the Ehrlich ascites carcinoma (EAC) model in mice compared to free GCBE followed by immunohistochemical analysis of caspase-3 and estrogen receptor. The optimized GCBE-SLNs results of the MTT assay exhibited a concentration-dependent reduction in the viability of MCF-7 with approximately 36 times more toxic effect against MCF-7 compared to free GCBE. The results of the in vivo Ehrlich ascites carcinoma model revealed that GCBE-SLNs cream exhibited statistically significant higher expression of caspase-3, lower expression of estrogen receptor, and increased necrotic index compared to the control group. Conclusively, GCBE-SLNs cream seems to have reassuring promises as anticancer remediation in both in vivo and in vitro studies. The present work is considered the first pre-clinical evidence for the potential merits of GCBE-SLNs in cancer management.

Comparison of proteomic profiles and biological properties for corneal wound healing of canine amniotic membrane and its extracts.

The application of canine amniotic membrane (cAM) for corneal reconstruction is widely used in the veterinary field. However, the information on biological properties and alternative forms of cAM for corneal wound healing is limited. This study aimed to investigate the proteomic profiles and corneal wound healing properties of cAM, cAM extract (cAME), and lyophilized cAM extract (cAMX). A total number of 14 cAMs were sterilely harvested from healthy full-term puppies and randomly divided into three different forms: cAM (n = 14), cAME (n = 14), and cAMX (n = 14). Each form of cAMs was subjected to proteomic analysis using label-free liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), followed by bioinformatic analysis. The proteins were classified into properties by comparing them with the literature search on human amniotic membrane (hAM) properties and the effect on corneal wound healing when given topically. The analyses identified 8136 proteins in cAM, 8211 proteins in cAME, and 7093 proteins in cAMX. A total number of 100 proteins were matched with proteins in hAM properties and were classified into anti-inflammatory, anti-fibrotic, anti-microbial, anti-angiogenic, promotion of epithelialization, analgesic, and support cell adhesion and growth properties. Furthermore, proteins with corneal wound healing effects were identified in cAME and cAMX. cAM and its extracts contain numerous proteins, including proteins related to corneal wound healing properties. Additionally, cAME and cAMX showed proteins involved in corneal wound healing and their potential benefits for topical use in ophthalmology.

N-Chlorotaurine Solutions as Agents for Infusion Detoxification Therapy: Preclinical Studies.

N-chlorotaurine (NCT) is a broad-spectrum antimicrobial agent with outstanding tolerability, effective for topical and inhalation use. This paper presents the results of studies of single and repeated intravenous infusions of NCT to laboratory animals. The studies were conducted on female Wistar Han rats. The effect of NCT infusions on the general condition, behavioral reactions, main biochemical and hematological parameters, hemocoagulation system, cardiovascular system, and on the condition of the internal organs was studied. It was found that NCT infusions do not reveal deviations in the studied parameters that could indicate a toxic effect. The estimated LD50 is more than 80 mg/kg. In a subchronic experiment, a statistically significant decrease in cholesterol (by up to 11%), glucose (by up to 15%) and excess bases (up to four times) in the blood, and an increase in heart rate (by up to 31%) and frequency of defecations (by up to 35%), as well as pronounced antiplatelet effect, were found. In animals with simulated endotoxicosis, a decrease in the cytolysis and oxidative stress markers was observed. Such effects are caused by both chlorine-active compounds and taurine.The results obtained indicate broad prospects for the use of NCT solutions as an infusion detoxifying agent.

Therapeutic Effect of Liquiritin Carbomer Gel on Topical Glucocorticoid-Induced Skin Inflammation in Mice.

Glucocorticoids are often used and highly effective anti-inflammatory medications, but prolonged topical application may alter the epidermis' normal structure and function, potentially resulting in a number of adverse effects. Topical glucocorticoid-induced skin inflammation is a dangerous condition that develops after topical glucocorticoid use. The patients become dependent on the medication and, even after the medication is stopped, the dermatitis symptoms recur, severely impairing their quality of life. Thus, the need to aggressively confront Topical glucocorticoid-induced skin inflammation is critical. Prior research has demonstrated that topical administration of licorice's flavonoid component liquiritin stimulates epidermal proliferation, which in turn enhances the creation of collagen and the healing of wounds. Therefore, the purpose of this work was to determine if topical use of liquiritin carbomer gel can treat glucocorticoid-induced changes in mice skin epidermal function, and the mechanisms involved. The findings demonstrated that, in the mice model of topical glucocorticoid-induced skin inflammation, liquiritin carbomer gel aided in the restoration of skin barrier function. These outcomes may have been caused by enhanced expression of the proteins Aquaporin 3, Keratin 10, and Claudin-1, as well as the restoration of epidermal hyaluronan content. In the meantime, liquiritin carbomer gel dramatically decreased the expression of TNF-α, IL-1β, IL-6, IFN-γ, and IgE in mice, according to ELISA tests. Furthermore, topical treatment of liquiritin carbomer gel boosted the expression of superoxide dismutase, catalase, and decreased malondialdehyde expression, potentially counteracting the detrimental effects of glucocorticoids on the epidermis. In summary, these findings imply that topical liquiritin carbomer gel can treat glucocorticoid-induced skin damage through various mechanisms of action.

Microparticles Made with Silk Proteins for Melanoma Adjuvant Therapy.

Melanoma is one of the most aggressive forms of skin cancer, which is characterized by metastasis and poor prognosis due to the limited effectiveness of current therapies and the toxicity of conventional drugs. For this reason and in recent years, one of the most promising strategies in the treatment of this form of cancer is the use of drug delivery systems as carriers capable of conveying the therapeutic agent into the tumor microenvironment, thus preventing its degradation and improving its safety and effectiveness profiles. In the present work, microparticles based on silk fibroin and epifibroin 0039, silk-derived proteins loaded with idebenone, were created, which act as therapeutic carriers for topical use in the treatment of melanoma. The resulting particles have a spherical shape, good loading efficiency, and release capacity of idebenone. Efficacy studies have demonstrated a reduction in the proliferation of COLO-38, melanoma tumor cells, while safety tests have demonstrated that the microparticles are not cytotoxic and do not possess prosensitizing activity. Notably, transdermal release studies revealed that all particles released idebenone over more days. The analysis of the stimulatory markers of the proinflammatory process, CD54 and CD86, did not show any increase in expression, thus confirming the absence of potential prosesensitization effects of the silk fibroin-based particles. The research, therefore, found that idebenone-loaded silk protein microparticles could effectively reduce the proliferation of melanoma cells without cytotoxicity. This indicates the promise of a safe and effective treatment of melanoma.

Efficacy and Safety Assessment of Topical Omega Fatty Acid Product in Experimental Model of Irritant Contact Dermatitis: Randomized Controlled Trial

Contact dermatitis is a common inflammatory skin disease that often requires prescription therapy and is associated with adverse reactions. Omega fatty acids have been recognized for their anti-inflammatory effect and could serve as a safer option in contact dermatitis treatment. Therefore, the aim of this randomized controlled study, conducted at the University of Split School of Medicine, was to evaluate the efficacy and safety of omega fatty acids containing topical products in an experimental model of irritant contact dermatitis. This study was registered with ClinicalTrials (NCT06189144) and is closed. The primary outcomes were levels of transepidermal water loss, skin hydration, and skin erythema, all measured using an MPA6 device in 25 healthy participants. A significant difference was observed between the hydration values of the intervention (45.7 ± 12.4) and control groups (31.6 ± 12.3) (p &lt; 0.05) on final measurements (day 10). Moreover, higher erythema levels were observed in participants who were smokers, compared to non-smokers. No adverse drug reactions were observed during the study period. In conclusion, omega fatty acids topical product use shows promise in the treatment of irritant contact dermatitis, and further studies are needed to evaluate efficacy in a larger sample of patients.

Use of Topical Minocycline for Treatment of Confluent and Reticulated Papillomatosis

Confluent and reticulated papillomatosis (CRP) is a rare dermatosis initially that typically affects young adults and is characterized by scaly, hyperpigmented macules or papillomatous papules combining into patches typically involving the upper trunk and neck. Herein, we report two cases of CRP successfully treated with topical minocycline. The most widely accepted treatment of CRP to date is oral minocycline. Due to the chronic nature of CRP, topical minocycline could be considered a better first-line treatment option. This alternative treatment offers the advantage of a targeted, local application for enhanced skin bioavailability and efficacy. This case supports the possibility of topical minocycline use as an alternative to long-term oral antibiotics for treatment of CRP.

Insight into Current Practices of Community Pharmacists in Topical Corticosteroid Prescribing and Counseling: Cross-Sectional Survey Study from Saudi Arabia.

Topical corticosteroids are commonly used to treat several skin conditions, most notably atopic dermatitis. Many studies have found that patients lack knowledge about the safety, potency, and appropriate use of topical corticosteroids. This can be due to ineffective education by pharmacists and other healthcare providers. This study aims to evaluate the appropriateness of dispensing and counseling practices of community pharmacists towards topical corticosteroids in Saudi Arabia. A cross-sectional survey study was conducted in Saudi Arabia among 418 community pharmacists from different regions of Saudi Arabia. Data were collected using a validated questionnaire that covered community pharmacists' sociodemographic information, their perceptions of patient knowledge about topical corticosteroid use, and their dispensing and their counseling practices, in addition to their perceived barriers to counseling. The majority of the participating community pharmacists were Saudi (57.4%), female (66.7%), holding a bachelor's degree (63.4%), and full-time workers (91.1%). Most of the time, community pharmacists counseled patients on the frequency of application per day and the duration of treatment (75.8% and 74.8%, respectively). The median counseling practice score was 17, with an IQR of 14-21. The main barrier to counseling was lack of time (33.7%). Only 15% of community pharmacists accurately identified all scenarios that necessitate medical referrals. Dry skin, itchiness, and irritation were the most common side effects reported by community pharmacists for patients to complain about (69.4%). Most pharmacists agreed that misuse is the most likely cause of topical corticosteroid adverse drug events (53.7%), followed by medication overuse, such as patient self-treatment (48%). Community pharmacists counseling practices to their patients about the use of topical corticosteroids require improvement. Continuing education and hands-on training are needed for community pharmacists regarding counseling about topical corticosteroids use.
