RESUMO
Background: The human skin, with a pH of 4 to 6, serves as a barrier against external pathogens. Alkaline handwash products (HWPs) can compromise this barrier and are widely used following the Coronavirus disease-2019 (COVID-19) pandemic. This study aims to determine the pH of a sample of HWPs in Riyadh, Saudi Arabia, and assess the effect of environmental factors on their pH. Methods: This is a cross-sectional, descriptive, observational study carried out in Riyadh, Saudi Arabia. The study involved a convenience sample of 33 liquid soaps, soap bars, and synthetic detergents (Syndets) from various brands. The pH of the handwash products was measured using laboratory-validated techniques. Data analysis was conducted using RStudio 2022 software. Results: Of the HWPs, 16 (48.5%) had a highly alkaline pH (≥10), while 14 (42.4%) had an acidic pH (4.0-6.9). Most liquid soaps were acidic (84.6%), with a mean pH of 5.9, whereas soap bars had a mean pH of 10.3. Syndets had a mean pH of 6.0. Conclusions: On average, liquid soaps and syndets offered a more physiological pH than soap bars. Liquid soaps were more affordable than synthetic detergents, making them a better value option among the three types of HWPs. Environmental factors such as exposure to hot weather did not have a significant impact on HWPs.
RESUMO
Androgenetic alopecia (AGA) is a widespread type of hair loss that affects both males and females. Advanced age and family history of AGA are well-established risk factors for developing AGA. The second to fourth digit ratio (2D:4D) is the ratio between the length of the index and ring fingers. This ratio has been utilized as a predictor for multiple hyperandrogenism-related medical conditions. More recently, 2D:4D was investigated as a predictor for AGA. This article aims to investigate the evidence supporting the use of 2D:4D as a predictor of AGA, and address areas of future research.
RESUMO
Linear porokeratosis (LP) is an epidermal keratinization disorder manifesting in the form of annular plaques with an atrophic center and hyperkeratotic margins. Although rare, LP carries a significant risk of skin cancer. Histological examination usually reveals the cornoid lamella, a parakeratosis column visualized in the outer layer of the epidermis. First-line treatment of LP is retinoids. However, the effects of combination therapy of isotretinoin and topical statins on LP are not well-understood. Herein, we attempted treatment with both isotretinoin and 2% cholesterol/atorvastatin ointment, with considerable improvement observed using the former but not the latter. These findings suggest that 2% topical cholesterol/atorvastatin treatment may not carry any additional benefits, even if used alongside retinoids. Further studies are needed to assess the potential effects of statins on LP.
RESUMO
Acne vulgaris (AV) is the eighth most common disease in the world. This condition can impair the affected patients' social and psychological functioning and lower their quality of life. In general, scar reduction, rather than complete scar removal, is the aim of AV treatment. Dermal abrasion, chemical peeling, laser resurfacing, subcision, punch methods, tissue-improving substances, and dermal fillers are the currently available therapeutic options. In this study, we focused on the rapidly developing field of dermal fillers used alone or in combination with other therapies to reconstruct skin affected by acne scars and to evaluate the improvement of facial appearance after using different types of dermal fillers.
RESUMO
Background: Atopic dermatitis (AD) negatively affects the quality of life (QoL). However, few studies from Saudi Arabia have assessed the effect AD has on the QoL of pediatric patients. Objective: To determine the psychological impact of AD on pediatric Saudi patients using the Children's Dermatology Life Quality Index (CDLQI). Methods: This cross-sectional was conducted across five tertiary hospitals located across five cities of Saudi Arabia from December 2018 to December 2019. The study included all Saudi patients aged 5-16 years who were diagnosed with AD for at least 6 months prior to visiting the dermatology clinic of the included hospitals. The quality of life in children with AD was assessed using the Arabic version of the CDLQI. Results: A total of 476 patients were included, of which 67.4% were boys. AD had a very large and extremely large effect on the QoL in 17.4% and 11.3% of the patients, respectively; the QoL of only 5.7% of the patients was not impacted due to AD. The average CDLQI score was not significantly different between males and females (9.7 vs. 9.1, respectively; P = 0.4255). Domains related to symptoms and emotions were affected to a greater extent compared with the remaining domains, while the school domain was the least affected. The correlation between age and CDLQI (r = 0.04, P = 0.52) and between the duration of the disease and CDLQI (r = 0.062, P = 0.18) was not significant. Conclusions: This study found that AD affects the QoL of a significant proportion of the Saudi pediatric patients, thereby highlighting the need to consider QoL as a measure of treatment success.
RESUMO
Sclerosing lymphangitis is a rare penile lesion characterized by a cord-like, firm swelling at the penile coronal sulcus. It affects males between the ages of 30 and 40 and usually resolves spontaneously. Due to the rarity of this condition, we decided to report this case. Herein, we present a case of a 35-year-old male that was evaluated for a painless, cord-like, penile lesion that enlarges during erection, characteristic of sclerosing lymphangitis.
RESUMO
Antibiotic resistance is a worldwide public health emergency. Nonprescription antibiotic use is a chief cause of antibiotic resistance. The Saudi Government, as a consequence, imposed in 2018 executive regulations to prevent the distribution of antibiotics without a prescription. Herein, we aimed to investigate the prevalence of and risk factors for nonprescription antibiotic use among individuals presenting to one hospital in Saudi Arabia after enacting these regulations. This cross-sectional study was conducted on people, aged ≥18 years, who presented to the primary healthcare clinics of King Khalid University Hospital in Riyadh during the period between 1/1/2019 and 28/2/2019. Participants were asked to fill out a self-administrated questionnaire assessing their nonprescription antibiotic use during the past year in addition to sociodemographic information. Then, logistic regression analyses were performed to calculate the odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for age, sex, education, and nationality of any nonprescription antibiotic use compared with no use within the past year. Out of 463 participants, 62.9% were females, 67.4% were <40 years, and 93.7% were Saudi citizens. Overall, 30.5% of participants reported nonprescription antibiotic use during the past year (19.7% one to two times and 10.8% more than two times). Male and non-Saudi participants were more likely to report any nonprescription antibiotic use, with HRs (95% CIs) of 1.99 (1.30, 3.04) and 3.81 (1.73, 8.35), respectively. The main reasons behind nonprescription antibiotic use were having previous experience with a health condition (69.2%), inaccessibility of healthcare (26.6%), and recommendation from a relative or a friend (16.1%). A major limitation of this study was that it included individuals attending one hospital. Individuals who seek medical consultation could be dissimilar to those who do not see doctors regarding nonprescription antibiotic use.
