Tazarotene is as effective and tolerable as imiquimod in the treatment of verruca plana, a comparative randomized clinical trial.

BACKGROUND: Plane warts when multiple and recurrent present a therapeutic challenge acting as a source of reinfection causing frustration and affecting patient's quality of life. For lesions of large numbers in cosmetically significant sites, topical treatment is preferred to avoid potential sequelae. OBJECTIVES: To evaluate and compare the efficacy and tolerability of tazarotene 0.1% gel versus imiquimod 5% cream for the treatment of plane warts. METHODS: In a parallel three-arm randomized controlled trial, 60 patients were randomized into imiquimod, tazarotene or placebo groups. Patients applied the corresponding treatment once daily at night for a maximum of 12 weeks. Primary outcomes were percentage of respondents with complete clearance in the three studied groups, the type and frequency of side effects in each group. RESULTS: Both active treatments resulted in significant improvement compared to baseline and to placebo group (P=0.001). Imiquimod 5% treated group showed complete clearance in 50% of cases, partial response in 15%, and no response in 35%. Tazarotene 0.1% gel showed complete clearance in 40% of cases, partial response in 40%, and no response in 20%. No significant difference was detected between imiquimod and tazarotene groups (P=0.190). CONCLUSIONS: Compared to imiquimod, tazarotene 0.1% gel for the treatment of plane warts seems to offer equivalent treatment response, maintained efficacy without recurrence, safer profile regarding dyspigmentation with an advantageous cheaper cost.

Grasping knowledge, attitude, and perception towards monkeypox among healthcare workers and medical students: an Egyptian cross-sectional study.

Background: Monkeypox (Mpox) is a re-emerging infectious disease representing a new global challenge. It poses a substantial threat to countries, particularly those with a low number of cases. Due to its popularity as a tourist destination and its proximity to many African refugees, Egypt is potentially at risk of Mpox importation. Therefore, effective disease management necessitates healthcare workers (HCWs) to possess adept knowledge, along with a positive attitude and behavior. The study aimed to assess the knowledge, attitude, and perception of Egyptian HCWs and medical students towards human Mpox. Methods: The present cross-sectional study data was collected from participants between October and December 2022 via a questionnaire. The questionnaire comprised 31 questions in the knowledge section, 11 questions in the attitude section, and 14 in the perception section. Results: The present study involved a total of 1,034 HCWs and medical students. It was found that 55.3% of the participants demonstrated adequate knowledge about Mpox, whereas 44.5% and 39.8% of the respondents exhibited favorable attitudes and perceptions towards the disease, respectively. Binary logistic regression analysis revealed that adequate knowledge was significantly observed in ages older than 40 years (p < 0.001), married participants (p < 0.001), and doctors (p < 0.001). The positive attitude was significantly observed among the male sex (p = 0.045), urban residents (p = 0.002), and nurses (p = 0.002). Conversely, married participants (p = 0.013), doctors (p < 0.001), and individuals employed in pharmacy and laboratory departments (p < 0.001) experienced an increase in positive perception. Conclusion: Knowledge, attitude, and perception towards Mpox among Egyptian HCWs and medical students exhibit suboptimal levels. Addressing these gaps is crucial to controlling and effectively preventing disease transmission.

Triple Intralesional Antigen Immunotherapy versus Monoantigen in the Treatment of Multiple Recalcitrant Warts.

INTRODUCTION: Warts can be resistant to treatment or recur despite the use of various destructive and immunotherapeutic modalities. Combination immunotherapy might contribute to better response rates. The aim of this study was to assess the effectiveness and safety of a triple intralesional immunotherapy combination composed of purified protein derivative (PPD), Candida antigen, and measles-mumps-rubella vaccine (MMR), versus each agent alone, in the management of multiple recalcitrant warts. METHODS: In total, 160 patients with numerous resistant extragenital warts were included in the research. They were randomly assigned to one of four groups (each with 40 patients): PPD, Candida antigen, and MMR, or combination of the three antigens. Injections into the biggest wart were repeated every 2 weeks until clearance or for a total of five sessions. RESULTS: Complete wart clearance was reported in 31 patients (77.5%) who received triple-antigen immunotherapy, 23 patients (57.5%) who received intralesional PPD, 29 patients (72.5%) injected with Candida antigen, and 25 patients (62.5%) who received MMR. The combined therapy was found to be superior to the other therapies and had the lowest recurrence rate, but the difference was not statistically significant. CONCLUSIONS: Triple intralesional antigen immunotherapy is as safe as, and more effective than, monoantigen immunotherapy, and can be added to the armamentarium against recalcitrant human papilloma virus (HPV) infections.

H syndrome: A review of treatment options and a hypothesis of phenotypic variability.

H syndrome is a rare autosomal recessive disorder with clinical features comprising: hyperpigmentation, hypertrichosis, hearing loss, heart anomalies, low height, hypogonadism and hepatosplenomegaly. H syndrome results from loss-of-function mutations in SLC29A3 which leads to abnormal proliferation and function of histiocytes. Herein, we discuss the considerable phenotypic heterogeneity detected in a consanguineous Egyptian family comprising of four affected siblings, two of which are monozygotic twin and the possible therapeutics. The phenotypic variability may be attributed to the role of histiocytes in the tissue response to injury. Such variable expressivity of H syndrome renders the diagnosis challenging and delays the management. The different treatment approaches used for this rare entity are reviewed.

Practical compendium for psoriasis management.

Psoriasis management is complex and challenging. It should be tailored for each patient. Treatment strategy differs according to patient's age, sex, disease type, disease severity, burden on patient's quality of life, comorbidities, involvement of specific sites, and pregnancy. The choice of the appropriate therapeutic must take into consideration the availability, the price, and the patient's preferences. It is very important that the chosen treatment is not more unpleasant, intolerable, or dangerous than the disease itself. According to the disease type, severity, and effect on patient's quality of life, dermatologist chooses whether to start with topical therapy, phototherapy or systemic therapy, or a combination of two or more of them. Under each category, there are different types of therapies that can be the first line therapeutics, second line, or even contraindicated. In this compendium, we provide dermatologists with different treatment plans considering all the mentioned variables so that a dermatologist can choose the optimum plan for the patient.
