RESUMO

BACKGROUND: Acne vulgaris (AV) is a chronic inflammatory skin condition affecting the pilosebaceous unit, commonly presenting as comedones, papules, pustules, or nodules on the face, upper limbs, torso, and back, with comedones formation being the primary pathology leading to disfiguring inflammation, hyperpigmentation, scarring, and psychological impact. AIM: The purpose of this study was to investigate the significance of two genetic variants in the promoter region of the tumor necrosis factor-alpha (TNF-α) gene and their association with insulin resistance (IR) in acne patients. To understand how these variants contribute to AV and its associated IR. SUBJECTS AND METHODS: An analytical cross-sectional study with a case-control design and research evaluation was carried out on 87 AV patients and 73 healthy volunteers. The medical histories of both groups were obtained, as well as the severity and duration of inflammation among acne sufferers, as well as demographic data. Biochemical analysis was performed on both sets of participants, including fasting blood glucose levels, insulin levels while fasting, IR, and serum TNF-α. PCR-RFLP analysis identified -863 G > A (rs1800630) and -308 G > A (rs1800629) variations, and real-time PCR analysis evaluated TNF-α gene expression in both patients and healthy people. RESULTS: Acne patients exhibited significantly higher levels of IR, fasting glucose, fasting insulin, serum TNF-α, and TNF-α folding change, when compared to healthy controls. The co-dominant model for -863 G > A and -308 G > A variants exhibited significant variations between the two groups. Severe acne patients who had the A/A genotype for -308 variants exhibited higher levels of IR, serum TNF-α, and TNF-α folding change. Highly significant positive linear correlation between IR, serum TNF-α, and TNF-α folding change in severe AV. CONCLUSION: There is a correlation between AV, especially severe acne, and the -863 G > A and -308 G > A polymorphism, which influences TNF-α gene expression and serum TNF-α levels.

RESUMO

BACKGROUND: Macrophage scavenger receptor 1 gene (MSR1), is responsible for producing macrophage scavenger receptors. MSR1 is primarily located on the surfaces of various macrophage types and is known to exert a range of effects on the human body. These effects include influencing innate and adaptive immunological reactions, as well as contributing to the development of conditions such as atherosclerosis, dyslipidemia, liver and lung disease, and cancer. The unregulated assimilation of lipoproteins by MSR1 leads to the creation of macrophages rich in cholesterol that manifest as foam-like cells, ultimately contributing to dyslipidemia. This occurrence highlights the significance of MSR1 as a key player in the pathophysiology of dyslipidemia. AIM: In this study, we aimed to estimate variation in lipid profile in acne vulgaris (AV) patients. Also, we aimed to investigate the role of MSR1 in lipid profile variation. SUBJECTS AND METHODS: A case-control study consisting of 100 patients with AV and 104 healthy controls. Lipid profiles were assessed using normalized enzymatic processes and genotype analyses were performed by a polymerase chain reaction and standard Sanger sequencing. Predictions of variant effects were performed using in silico tools. RESULT: Our results indicated that the levels of lipid profile were higher in patients with AV than in healthy patients. The two haplotypes that were most prevalent in the patients were TCAC (16.5%) and CAGG (15.47%), whereas the two haplotypes that were more prevalent in the controls were TAAC (16.43%) and CCAC (15.62%). IVS5.59 C > A and rs433235 A > G are in linkage disequilibrium. Additionally, rs433235 A > G has a significant linkage disequilibrium with rs3747531 C > G. In silico analysis, tools indicated that the rs433235 A > G variant was disease-causing. CONCLUSION: Patients diagnosed with TCAC and CAGG exhibited a higher prevalence compared to healthy patients with TAAC and CCAC. The linkage disequilibrium between rs433235 A > G and IVS5.59 C > A has been established. Furthermore, there appears to be significant linkage disequilibrium between rs3747531 C > G and rs433235 A > G. These findings support the notion that genetic variations may play a critical role in the pathogenesis of these conditions.

RESUMO

BACKGROUND: Although cervical cancer is potentially preventable, lack of knowledge and poor attitude among healthcare professionals toward cervical cancer screening and Human Papilloma Virus (HPV) vaccination can result in underutilization of these preventive strategies. Then, the objective of this study was to assess the knowledge, attitude, and practice of cervical cancer and its prevention through Pap test screening and HPV vaccination among obstetricians and gynecologists (Ob-Gyns). METHODS: A cross-sectional study was conducted on 250 Egyptian attendees of a national Ob-Gyns professional conference. Data collection was performed using a pre-designed self-administered questionnaire, which tested participants' knowledge, attitude, and practices related to cervical cancer, Pap test screening, and HPV vaccination. RESULTS: The study included 41.2% Ob-Gyns specialists and 37.6% of consultants from secondary and tertiary care hospitals or centers. About 45% of participants had poor-to-fair knowledge, 57% had negative-to-fair positive attitudes toward cervical cancer screening and HPV vaccination, and 44% had ever-performed Pap test, while 45% of participants had ever-prescribed the HPV vaccine to their patients. Physicians' knowledge and attitude were significantly associated with their age, professional level, work experience, and place of work. Although performing cervical cancer screening was significantly more common among older, more experienced, and highly professional participants, HPV vaccine prescription was associated with young, less experienced participants at lower educational and professional levels. CONCLUSION: Ob-Gyns had poor-to-fair knowledge, Attitude, and practices related to cervical cancer, Pap test screening, and HPV vaccination.

RESUMO

No universal consensus about optimal modality for treating the recalcitrant multiple common warts (RMCW). The objective of the study was to evaluate the immunological mechanisms and clinical therapeutic effect of using lipid garlic extract (LGE) in the treatment of RMCW. The study included 50 patients with RMCW. They were randomly assigned into two groups: the first group (25 patients) received LGE, and the second group (25 patients) received saline as a control group. In both groups, treatments were made to single lesions, or largest wart in case of multiple lesions, until complete clearance of lesions or for a maximum of 4 weeks. Blood serum was taken at pre-study and at the fourth week to measure tumor necrosis factor alpha (TNF-α) level. A significant difference was found between the therapeutic responses of RMCW to LGE antigen and saline control group (p < 0.001). In the LGE group, complete response was achieved in 96% of patients presenting with RMCW. There was a statistically nonsignificant increase in TNF-α of LGE group versus saline group. No recurrence was observed in the LGE group. LGE as an immunotherapy is an inexpensive, effective, and safe modality with good cure rates for treatment of RMCWs, when other topical or physical therapies have failed.

RESUMO

BACKGROUND: Topical Cyperus rotundus oil is an effective and safe method to decrease hair growth. The oil's flavonoids have antiandrogenic activity on androgenic hair. To date, there have been no randomized controlled trials comparing topical C rotundus oil to the available allopathic modalities, such as laser-assisted hair removal. OBJECTIVES: In an open-label pilot study, the author prospectively evaluated the efficacy of C rotundus essential oil, compared with the Alexandrite laser (GentleLase; Candela Laser Corp, Wayland, Massachusetts) and saline, for reducing unwanted axillary hair. METHODS: Eligible participants (n=65) with unwanted axillary hair were assigned randomly to 1 of 3 study groups: topical C rotundus oil (group 1), saline (group 2), and Alexandrite laser (group 3). Sixty patients completed the entire study. Three methods were used to evaluate the results: hair counts, observations of independent professionals, and patient self-assessments. RESULTS: Overall results did not differ significantly between C rotundus oil and the Alexandrite laser (P>.05). However, statistically significant differences were noted with respect to decreased growth of white hair (P<.05), favoring the oil. This finding was evident by all 3 methods of assessment. No side effects were detected. CONCLUSIONS: Cyperus rotundus essential oil is as effective as the Alexandrite laser for decreasing the growth of axillary hair (both dark and white). LEVEL OF EVIDENCE: 3.
