OBJECTIVES: This study aims to evaluate the prevalence and degree of topical corticosteroid phobia and its impact on treatment adherence in various dermatological conditions. Additionally, we explored the sources of information regarding topical corticosteroids.
MATERIALS AND METHODS: A cross-sectional study was conducted among 300 participants with topical corticosteroid usage experience. Topical corticosteroid phobia was assessed with the topical corticosteroid phobia (TOPICOP) scale, and treatment adherence was measured with the Elaboration d'un outil d'evaluation de l'observance des traitements medicamenteux (ECOB) score. Information sources regarding topical corticosteroids were identified, and their level of trust was assessed. The data were collected via questionnaires in three languages, namely English, Malay and Mandarin.
RESULTS: The study found that topical corticosteroid phobia was prevalent, with 98% of participants expressing a certain degree of phobia. The mean global TOPICOP score was 32.7 ± 6.7%. The mean score of each domain was 27.1 ± 17.2% for knowledge and belief, 35.7 ± 23.8% for fears and 40.8 ± 25.8% for behaviour. Patients/caregivers who have eczema, highly educated, severe disease, low tolerability to symptoms, previous adverse effects with topical corticosteroids and tend to traditional/non-steroidal alternative therapy usage had a significant association with topical corticosteroid phobia (p<0.05). Dermatologists were the most common and trusted source of information on topical corticosteroids.
CONCLUSIONS: This study highlights the widespread topical corticosteroid phobia in dermatological practice. Dermatologists should take the lead in combating steroid phobia and provide patients with public awareness regarding topical corticosteroids to improve treatment adherence and therapeutic outcomes.
OBJECTIVE: To evaluate the efficacies and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin for the treatment of mild-to-moderate intertrigo, relative to 1% hydrocortisone cream.
METHODS: This randomized, double-blinded study enrolled 40 intertrigo patients. Twice daily, 20 patients applied adsorbent lotion while the remainder used 1% hydrocortisone cream. Efficacy evaluation, skin biophysical measurements, skin tolerability, safety, and visual analog scale (VAS) patient-satisfaction scores were evaluated at baseline and Week 2.
RESULTS: The adsorbent lotion showed higher complete cure rates for color, partial epidermal loss, papules/pustules/vesicles/patches, dryness, and scaling than the corticosteroid without statistical significance. Adsorbent lotion demonstrated significantly higher reduction in pruritus than the corticosteroid treatment. Reduction of erythema level using Mexameter and VAS patient-satisfaction scores were not statistically different between adsorbent lotion and hydrocortisone cream. No adverse effects or superimposed infections were reported.
CONCLUSIONS: The anti-inflammatory efficacies of adsorbent lotion and low-potency steroid were equivalent. The lotion was safe and produced excellent pruritus reduction. Patient satisfaction was high.
MATERIALS AND METHODS: Male rats were rendered diabetes mellitus via intraperitoneal injection of streptozotocin and nicotinamide. Following diabetes development, wound was created at the back of the neck. 1% and 2% mangiferin gel and 1% silver sulphurdiazine (SS) gel (positive control) were applied to the wound for twenty-one (21) days. Fasting blood glucose (FBG) levels were weekly monitored. At the end of the treatment, rats were sacrificed and wound was excised and subjected for histopathological and molecular biological analysis.
RESULTS: No changes to serum FBG levels was noted throughout the period of mangiferin treatment. Albeit, a significant decrease in the size of the wound with increased in the skin thickness of surrounding the wound were observed. Increased expression and distribution of EGF, FGF, TGF-β, VEGF, PI3K, MMP and Nrf2 and decreased expression and distribution of TNFα and NF-κB p65 were observed in diabetic wound treated with topical mangiferin.
CONCLUSIONS: Mangiferin has potential to be used as an agent to promote wound healing in diabetic condition.
DATA SOURCES: EMBASE, MEDLINE, CENTRAL, and ISI Web of Science were systematically searched from their inception until May 31, 2019.
REVIEW METHODS: Parallel-arm randomized controlled trials were included.
RESULTS: Seventy-one trials (7539 participants: orthopedics 5450 vs nonorthopedics 1909) were included for quantitative meta-analysis. In comparison to placebo, topical TXA significantly reduced intraoperative blood loss [mean difference (MD) -36.83 mL, 95% confidence interval (CI) -54.77 to -18.88, P < 0.001], total blood loss (MD -319.55 mL, 95% CI -387.42 to -251.69, P < 0.001), and incidence of blood transfusion [odds ratio (OR) 0.30, 95% CI 0.26-0.34, P < 0.001]. Patients who received topical TXA were associated with a shorter length of hospital stay (MD -0.28 days, 95% CI -0.47 to -0.08, P = 0.006). No adverse events associated with the use of topical TXA were observed, namely mortality (OR 0.78, 95% CI 0.45-1.36, P = 0.39), pulmonary embolism (OR 0.73, 95% CI 0.27-1.93, P = 0.52), deep vein thrombosis (OR 1.07, 95% CI 0.65-1.77, P = 0.79), myocardial infarction (OR 0.79, 95% CI 0.21-2.99, P = 0.73), and stroke (OR 0.85, 95% CI 0.28-2.57, P = 0.77). Of all included studies, the risk of bias assessment was "low" for 20 studies, "unclear" for 26 studies and "high" for 25 studies.
CONCLUSIONS: In the meta-analysis of 71 trials (7539 patients), topical TXA reduced the incidence of blood transfusion without any notable adverse events associated with TXA in adults undergoing surgery.
PROSPERO: CRD 42018111762.
METHODS: Nine AD experts from South and East Asia and one from Europe developed the algorithm based upon treatment guidelines, relevant literature and local treatment practices. The algorithm outlines current best practice for the use of emollients, topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI), with the intention of simplifying the treatment regimen of mild-to-moderate AD in South and East Asia.
RESULTS: Patients with AD should bathe and cleanse affected skin to remove crusts and scales daily. Emollients should also be applied daily as a maintenance treatment. When selecting appropriate topical anti-inflammatory treatment for AD flares, several factors should be taken into consideration, including the patient's age, attitude to treatment options and site of AD lesions. Given the concerns regarding the risk of skin atrophy with use of TCS, a TCI should be used to treat AD lesions in sensitive skin areas: pimecrolimus is recommended for mild-to-moderate AD in these locations, while tacrolimus should be considered for moderate and severe cases. Either pimecrolimus or tacrolimus is recommended for flares in other, non-sensitive body locations. A proactive or intermittent maintenance treatment strategy involving regular emollient use and twice-weekly application of a TCI to previously affected areas is encouraged to reduce the risk of flares.
CONCLUSIONS: The algorithm proposed here is intended to simplify the topical treatment of mild-to-moderate AD in daily practice in South and East Asian countries.
METHODS: Seventeen POAG patients with suboptimal IOP control despite pre-existing topical medications were subjected to adjunct SLT (50 applications 180 degrees) or second line medical therapy. Current medications were continued, and patients were followed up for 6 months for degree of intraocular pressure (IOP) lowering. HRQoL was assessed using Glaucoma Quality of Life 36-item (GlauQoL-36), Assessment of Quality of Life-7D (AQoL-7D) and Vision related Quality of Life (VisQoL). Costs involved were calculated and compared to the effect (IOP reduction) achieved in each arm.
RESULTS: Ten patients were in the SLT group and 7 in the topical medication (MED) group. Mean baseline intraocular pressure (IOP) was 18.90±3.48mmHg in SLT group and 15.57±2.23mmHg in MED group. Mean reduction of IOP was 4.30±1.64mmHg in SLT group and 2.71±2.56 mmHg in MED group at 6 months which was not statistically significant (p=0.14) between two groups. All the HRQoL questionnaires did not show significant changes in the groups or between groups when compared baseline with 6-month post treatment (p-values ranging from 0.247 to 0.987). For every 1mmHg reduction in IOP, cost involved in MED group (RM53.61) was 165% of the cost involved in SLT group (RM32.56).
DISCUSSION AND CONCLUSION: This study has shown that SLT was as effective clinically and tolerable as topical anti glaucoma medications and was possibly more cost effective in the step-up treatment of patients with POAG at 6 months follow- up.
Materials and Methods: An unblinded randomized controlled trial was undertaken at the dermatology clinic of a tertiary care hospital. Consent from the patients fulfilling inclusion criteria were obtained, and they were included in this study. They were randomized into two groups, namely Gp-1 (C and P labeling) and Gp-2 (conventional labeling). Both groups were assessed at week 0, 6, and 12 (visit 1, 2, and 3) using knowledge assessment list and psoriasis severity assessment score. For visit 2 (week 6), reinforcement of their understanding of topical treatment was performed.
Results: A total of 101 patients were recruited. Only 91 of them completed the study. The mean ages were 44.52 (±16.61) and 45.49 (±15.84) years, with 70.3% males and approximately half Malay ethnics. The changes of knowledge and comparison of Topical Application Assessment Score between the groups showed an incremental raise of significance with every visit (P = 0.006 [week 1], 0.004 [week 6], and 0.002 [week 12]). Psoriasis Area and Severity Index 75 could not draw any conclusion as patients who achieved >75% improvement were inadequate.
Conclusion: C and P labeling was effective in improving the understanding and knowledge of patients with psoriasis. Both groups showed improvement in body surface area and Dermatology Life Quality Index for every visit; however, it was statistically insignificant.
Objective: This article aimed to provide a narrative updated review on the evaluation, diagnosis, and treatment of tinea corporis.
Methods: A PubMed search was performed with Clinical Queries using the key term 'tinea corporis.' The search strategy included clinical trials, meta-analyses, randomized controlled trials, observational studies, and reviews. The search was restricted to the English language. The information retrieved from the mentioned search was used in the compilation of the present article.
Results: Tinea corporis typically presents as a well-demarcated, sharply circumscribed, oval or circular, mildly erythematous, scaly patch or plaque with a raised leading edge. Mild pruritus is common. The diagnosis is often clinical but can be difficult with prior use of medications, such as calcineurin inhibitors or corticosteroids. Dermoscopy is a useful and non-invasive diagnostic tool. If necessary, the diagnosis can be confirmed by microscopic examination of potassium hydroxide wet-mount preparations of skin scrapings from the active border of the lesion. Fungal culture is the gold standard to diagnose dermatophytosis especially if the diagnosis is in doubt and results of other tests are inconclusive or the infection is widespread, severe, or resistant to treatment. The standard treatment of tinea corporis is with topical antifungals. Systemic antifungal treatment is indicated if the lesion is multiple, extensive, deep, recurrent, chronic, or unresponsive to topical antifungal treatment, or if the patient is immunodeficient.
Conclusion: The diagnosis of tinea corporis is usually clinical and should pose no problem to the physician provided the lesion is typical. However, many clinical variants of tinea corporis exist, rendering the diagnosis difficult especially with prior use of medications, such as calcineurin inhibitors or corticosteroids. As such, physicians must be familiar with this condition so that an accurate diagnosis can be made and appropriate treatment initiated.
OBJECTIVE: The study aimed to provide an update on the evaluation, diagnosis, and treatment of onychomycosis.
METHODS: A PubMed search was completed in Clinical Queries using the key term "onychomycosis". The search was conducted in May 2019. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews published within the past 20 years. The search was restricted to English literature. Patents were searched using the key term "onychomycosis" in www.freepatentsonline.com.
RESULTS: Onychomycosis is a fungal infection of the nail unit. Approximately 90% of toenail and 75% of fingernail onychomycosis are caused by dermatophytes, notably Trichophyton mentagrophytes and Trichophyton rubrum. Clinical manifestations include discoloration of the nail, subungual hyperkeratosis, onycholysis, and onychauxis. The diagnosis can be confirmed by direct microscopic examination with a potassium hydroxide wet-mount preparation, histopathologic examination of the trimmed affected nail plate with a periodic-acid-Schiff stain, fungal culture, or polymerase chain reaction assays. Laboratory confirmation of onychomycosis before beginning a treatment regimen should be considered. Currently, oral terbinafine is the treatment of choice, followed by oral itraconazole. In general, topical monotherapy can be considered for mild to moderate onychomycosis and is a therapeutic option when oral antifungal agents are contraindicated or cannot be tolerated. Recent patents related to the management of onychomycosis are also discussed.
CONCLUSION: Oral antifungal therapies are effective, but significant adverse effects limit their use. Although topical antifungal therapies have minimal adverse events, they are less effective than oral antifungal therapies, due to poor nail penetration. Therefore, there is a need for exploring more effective and/or alternative treatment modalities for the treatment of onychomycosis which are safer and more effective.
OBJECTIVE: This article aimed to provide an update on the evaluation, diagnosis, and treatment of tinea capitis.
METHODS: A PubMed search was performed in Clinical Queries using the key term "tinea capitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature. The information retrieved from the above search was used in the compilation of the present article. Patents were searched using the key term "tinea capitis" at www.freepatentsonline.com.
RESULTS: Tinea capitis is most often caused by Trichophyton tonsurans and Microsporum canis. The peak incidence is between 3 and 7 years of age. Non-inflammatory tinea capitis typically presents as fine scaling with single or multiple scaly patches of circular alopecia (grey patches); diffuse or patchy, fine, white, adherent scaling of the scalp resembling generalized dandruff with subtle hair loss; or single or multiple patches of well-demarcated area (s) of alopecia with fine-scale, studded with broken-off hairs at the scalp surface, resulting in the appearance of "black dots". Inflammatory variants of tinea capitis include kerion and favus. Dermoscopy is a highly sensitive tool for the diagnosis of tinea capitis. The diagnosis can be confirmed by direct microscopic examination with a potassium hydroxide wetmount preparation and fungal culture. It is desirable to have mycologic confirmation of tinea capitis before beginning a treatment regimen. Oral antifungal therapy (terbinafine, griseofulvin, itraconazole, and fluconazole) is considered the gold standard for tinea capitis. Recent patents related to the management of tinea capitis are also discussed.
CONCLUSION: Tinea capitis requires systemic antifungal treatment. Although topical antifungal therapies have minimal adverse events, topical antifungal agents alone are not recommended for the treatment of tinea capitis because these agents do not penetrate the root of the hair follicles deep within the dermis. Topical antifungal therapy, however, can be used to reduce transmission of spores and can be used as adjuvant therapy to systemic antifungals. Combined therapy with topical and oral antifungals may increase the cure rate.
