Digital Dilemma of Cyberbullying Victimization among High School Students: Prevalence, Risk Factors, and Associations with Stress and Mental Well-Being.

Cyberbullying has emerged as a pervasive problem among high school students, with potentially severe consequences for their mental well-being. This study aimed to investigate the prevalence, risk factors, and associations of cyberbullying with stress and mental well-being among high school students in Zagazig, Egypt. A cross-sectional study was conducted among 562 high school students using a random sampling technique. The data were collected using a self-administered questionnaire that included the Cyberbullying Scale, Perceived Stress Scale (PSS-10), and General Health Questionnaire (GHQ-12). Descriptive statistics, independent samples t-tests, multiple regression, mediation, and logistic regression analyses were employed for data analysis. The prevalence of cyberbullying victimization was 38.3%, with 20.6% exposed to two or three cyberbullying behaviors and 4.1% exposed to four or more. Female students, those under 18 years old, those with lower educational achievement, and those with higher daily internet use were more likely to experience cyberbullying. Cyberbullied students reported significantly higher levels of perceived stress and poorer mental well-being compared to non-cyberbullied students. Perceived stress likely mediated the relationship between cyberbullying victimization and general psychological health. Cyberbullying is a significant problem among high school students in Zagazig, Egypt, with detrimental effects on their stress levels and mental well-being. Targeted interventions and prevention strategies are needed to address cyberbullying and promote the well-being of adolescents in the digital age.

Comparative analysis of effects induced by hyaluronic acid and its combined formula on skin functional parameters in second-degree photoaging.

BACKGROUND AND AIMS: The study aimed to compare the effectiveness of intradermal injections of modified hyaluronic acid (mHA) and combined injections of platelet-rich plasma (PRP) and mHA (HA-PRP) on clinical and functional parameters in women with second-degree photoaging. METHODS: Seventy-six healthy female participants diagnosed with second degree of skin photoaging were involved in two interventional study groups. The first group was treated with "bio-reparative" method (mHA) and the second group with "combined HA-PRP therapy". Additionally, 20 practically healthy women, with the first degree of photoaging according to Glogau classification, constituted the control group. Parameters of facial skin were evaluated in all groups before and after the injections. The patients in both interventional groups were compared based on skin therapy outcomes, using corneometry, sebumetry, cutometry, transepidermal water loss (TEWL), and skin pH assessments. A post-interventional analysis was conducted to evaluate the level of satisfaction in physicians and study participants in accordance with GAIS. Intragroup and between-group analysis for the selected parameters was performed. RESULTS: Compared with the control group, the combined therapy group did not show significant difference in parameters (p > 0.05) and the scores were significantly improved compared to mHA group (p < 0.001). Control and HA-PRP-treated groups were different only in sebumetry scores (SigDev = 2.1%). Significant difference was observed in the GAIS scores for patients between the interventional groups (p = 4.03297E-11 and 3.4093E-09, respectively). CONCLUSION: Implementation of combined therapy is significantly effective compared to the mHA therapy alone. The higher efficacy is derived from significant recovery of functional parameters and GAIS survey results.

Ichthyosiform mycosis fungoides.

Malignancy-associated acquired ichthyosis is well known, but the ichthyosiform subset of mycosis fungoides (MF) is rarely reported. We report on two patients with a clinical presentation for whom diagnosis of mycosis fungoides was established on histological grounds. In both cases, long term remission was obtained with non aggressive therapies. This rare condition must be added to newly described forms of MF with epidermal hyperplasia such as keratosis lichenoides chronica like MF and pilotropic MF.
