Knowledge and attitudes regarding topical misuse of corticosteroids in libya

Prescription drug misuse has emerged as a significant problem over the past decade, particularly topical corticosteroids for skin lightening. This study aimed to assess the misuse of topical corticosteroids among the female population in southern Libya; to determine prevalence, awareness, attitude, and practice regarding this drug misuse. A descriptive, cross-sectional questionnaire was distributed on January 2022 to females aged between 16-45 years old in southern Libya. Out of 200 distributed questionnaires, 155 were returned with a response rate of 77.5%. The majority of the participants were aged 16-25 years (n=138, 89.0%) and over two-thirds of participants, said they obtained lightening products containing cortisone from pharmacies (n=107, 69.0%) while 36 participants indicated they obtained these products from cosmetic shops (23.2%). More than three-quarters of the participants said they were aware that they should read product ingredients (n=120, 77.4%). Just over one-quarter of respondents indicated they used the product on their face almost daily (n=41, 26.5%) while 28 participants denied using it (18.1%). The most common source of information about topical corticosteroids among participants was the Internet (n=51, 32.9%), followed by dermatologists (n=41, 26.5%), and pharmacists (n=31, 20.0%). Almost half of respondents were aware that topical corticosteroids can cause harmful effects (n=75, 48.4%). The most common indications reported for using topical corticosteroids were whitening (23.3%), and acne treatment (54.2%). Over two-thirds of participants, declared they would not use topical lightening products if they contained corticosteroids (n=107, 69.0%). In a similar attitude, nearly a third of participants stated that they would never use corticosteroid medications again if they knew about the negative effects of whitening (n=51, 32.9%). The majority of females, (87.7%), concur that only pharmacies should be able to sell and prescribe topical corticosteroid medications. The study's findings indicate that topical corticosteroids are frequently misused and that to lessen contraindications, especially for prolonged use, it is imperative to provide basic care to females who continue using topical corticosteroids in public or unlicensed marketing settings.

Inhibition of hyperoxaluric calcium oxalate nephrolithiasis by macrotyloma uniflorum (lam.) verdc. seeds infusion on glass slide

Hyperoxaluria is a metabolic disorder responsible for calcium oxalate nephrolithiasis. The study was conducted on glass slides to observe the growth patterns of urinary calcium oxalate monohydrate crystals and their inhibition by 5, 10, 15 and 20 % infusion of Macrotyloma uniflorum seeds. For this purpose, a drop of gel medium (sodium metasilicate of 1.06 specific gravity and 3M acetic acid solution) at pH 5.02 - 5.17 was placed in the middle of a glass slide and converted into a gel. A 1 M oxalic acid drop was dropped to the left, and 1 M calcium chloride and magnesium acetate (1:1) solution was dropped to the right side of the properly formed gel. The glass slide was observed under a microscope till it was completely dried. In the case of the crystal inhibition study, a drop of M. uniflorum infusion was also added on the right side just after adding calcium chloride and magnesium acetate solution. The results without infusion showed detailed morphology and aggregation patterns of observed crystals such as donut, dumbbell, needles, platy, prismatic, rosette, round edges, X-shape crystals, loose and compact aggregates. All infusions of M. uniflorum affected the crystals, forming defective crystals. 5 % infusion inhibited crystals of all morphologies except donuts, X-shaped crystals, donuts, platy crystals and rosettes. Defected rosettes were observed in 10 % infusion, which was reduced gradually in the crowd by 15 and 20 %, respectively. From this study, it can be concluded that M. uniflorum seeds infusion is effective against calcium oxalate nephrolithiasis.

Anticancer potential of furanocoumarins: mechanistic and therapeutic aspects

Cancer is one of the most extreme medical conditions in both developing and developed countries around the world, causing millions of deaths each year. Chemotherapy and radiotherapy are critical treatment approaches, but both have numerous adverse health effects. Furthermore, the resistance of cancerous cells to anticancer medication leads to treatment failure. The rising burden of cancer overall requires novel, efficacious treatment modalities. Natural medications offer feasible alternative options against malignancy in contrast to western medicines. Furanocoumarins’ defensive and restorative impacts have been observed in leukemia, glioma, breast, lung, renal, liver, colon, cervical, ovarian, and prostate malignancies. Experimental findings have shown that furanocoumarins activate multiple signalling pathways, leading to apoptosis, autophagy, antioxidant, antimetastatic, and cell cycle arrest in malignant cells. Additionally, furanocoumarins have been shown to have chemopreventive and chemotherapeutic synergistic potential when used in combination with other anticancer drugs. Here, we address different pathways which are activated by furanocoumarins and their therapeutic efficacy in various tumors. Ideally, this review will trigger interest in furanocoumarins and their potential efficacy and safety as cancer-lessening agents.

Chapter 4.23 - vitamin e (tocopherols and tocotrienols) (natural-occurring antioxidant; bright and dark side). in: antioxidants effects in health. edited by seyed mohammad nabavi and ana sanches silva

Vitamin E is extensively available in the natural world and is produced by prototrophs such as plants, algae, and blue-green algae. Vitamin E is used as a dietary supplement, an antioxidant food stabilizer, a pharmaceutical additive, and a preservative in livestock feed. Several types of vitamin E can be differentiated by the position and number of the methyl functional group, and each form has a unique biological role. The function of antioxidants such as vitamin E is to defend cells from the effects of oxidative stress. Vitamin E is a free radical scavenger converted to vitamin E radical, then converted back to vitamin E by ascorbic acid. Vitamin E was discovered by Evans and Bishop in 1922; it has proved to be an effective nutrient for reproduction. It is also possible for vitamin E to act by a mechanism not directly linked to the inhibition of oxidation. Such non-antioxidant actions of vitamin E may result from gene regulation and specific cell signalling. The function of vitamin E in cellular signalling, especially its biological impact, is undoubtedly an imperative subject for future studies. The explicit roles of the several isomers and esters of vitamin E analogues should also be the subjects of future studies.
