PURPOSE: To evaluate the effect of the intracameral adrenaline and trypan blue used during cataract surgery on corneal endothelial parameters in pseudoexfoliation syndrome (PEX) patients. METHODS: The patients were divided into four groups according to intraoperative use of agents during cataract surgery: intracameral adrenaline (1/10,000, 0.1 ml) (group 1), trypan blue (0.6 mg/ml, 0.1 ml) (group 2), combination of adrenaline and trypan blue (group 3) and none (group 4). RESULTS: Preoperative ECD, CV, HEX and CCT parameters were similar between the groups. A mean loss of 12.7% in ECD was observed at the postoperative third months compared to the preoperative. In group 3, ECD was found to be lower in the postoperative third months compared to the preoperative ( = 0.014). In the other groups, no statistically significant difference was found in preoperative and postoperative comparisons. CONCLUSION: In conclusion, the utilization of intracameral adrenaline or trypan blue did not cause a significant difference in corneal endothelium in PEX patients. However, their combined use may have a negative effect on endothelial cell density. In a cataract surgery performed in the presence of PEX, the increased likelihood of endothelial damage should be taken into consideration, and appropriate precautions should be taken preoperatively and intraoperatively.

OBJECTIVE: This study aimed to evaluate how systemic antimony treatment in cutaneous leishmaniasis (CL) patients affects biochemical, hematological, and inflammatory parameters in child and adult patient groups. METHODS: A total of 50 patients (29 adults, 21 children) who received systemic meglumine antimonate (MA) treatment in the skin and venereal diseases clinic between September 2022 and January 2024 and were diagnosed with CL by microscopic examination were included in the study. The medical records of the patients were examined retrospectively. Before and after treatment, neutrophil count, leukocyte count, lymphocyte count, hemoglobin concentration, platelet count, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), amylase, lipase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen and serum creatinine levels were recorded. RESULTS: In the children group, lymphocyte and platelet values decreased statistically significantly; and lipase value increased statistically significantly after treatment. In the adult group; hemoglobin, neutrophil, lymphocyte and leukocyte values decreased statistically significantly; ALT, AST, amylase, lipase, NLR and PLR values increased statistically significantly after treatment. CONCLUSION: Based on the data in our study, it was stated that systemic meglumine antimonate treatment may lead to an increase in pancreatic enzymes and transaminases and bone marrow suppression. We also think that patients in the adult age group should be followed more closely regarding pancreatic enzymes and kidney function tests than the pediatric age group.

PURPOSE: The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of liver cancer patients. However, drug eruption associated with ICI monotherapy or combination therapy not only impacts the quality of life and treatment progress of liver cancer patients but also poses a potential threat to their lives. The study aims to investigate the risk factors of drug eruption in liver cancer patients undergoing ICIs in real-world settings. METHODS: We retrospectively collected data from liver cancer patients who underwent ICI therapies at the Third Affiliated Hospital of Sun Yat-sen University between 2021 and 2022. A propensity score matching (PSM) method was employed to match 31 liver cancer patients with ICI-related drug eruption (drug eruption group) to 228 liver cancer patients without immune-related adverse reactions (control group) in a 1:2 ratio, creating two groups of patients with comparable baseline characteristics. Subsequently, logistic regression analysis was then conducted to analyze the clinical risk factors associated with drug eruption caused by ICIs. RESULTS: Before PSM, there were statistically significant differences between the drug eruption group (31 cases) and the control group (228 cases) in two variables: Child-Pugh liver function classification and presence of vascular invasion (both < 0.05). However, after PSM, no statistically significant differences were found in the clinical variables between the drug eruption group (28 cases) and the control group (52 cases). Univariate analysis revealed significantly higher levels of aspartate amino-transferase, alanine aminotransferase, glutamyl transpeptidase, and systemic immune-inflammation index (SII) and a significantly lower rate of liver cancer resection surgery before immunotherapy in liver cancer patients with drug eruption compared to the control group ( < 0.05). Multivariate analysis indicated that an elevated SII level before immunotherapy was significantly associated with the occurrence of drug eruption in liver cancer patients treated with ICIs ( < 0.05). The predictive performance of SII before immunotherapy in liver cancer patients for ICI-related drug eruption yielded an area under the receiver operator characteristic curve of 0.852, with a critical value of 749.189. Sensitivity and specificity were determined as 85.7% and 75%, respectively ( < 0.05). CONCLUSIONS: Elevated systemic immune-inflammation index is identified as a risk factor for drug eruption occurrence in liver cancer patients treated with ICI therapies.

Test methods to inform hazard characterization and labeling of pesticides to protect human health are typically conducted using laboratory animals, and for skin irritation/corrosion the rabbit Draize test is currently required by many regulatory agencies. Although the Draize test is generally regarded to provide protective classifications for human health, new approach methodologies (NAMs) have been developed that offer more human relevant models that circumvent the uncertainty associated with species differences that exist between rabbits and humans. Despite wide applicability and use of these test methods across a broad range of chemicals, they have not been widely adopted for testing pesticides and pesticidal formulations. One of the barriers to adoption of these methods in this sector is low concordance with results from the Draize rabbit test, particularly for chemicals within the mild to moderate irritation spectrum. This review compares and contrasts the extent to which available models used in skin irritation testing mimic the anatomy and physiology of human skin, and how each aligns with the known key events leading to chemically-induced adverse skin irritation and corrosion. Doing so fully characterizes the human relevance of each method. As alternatives to the rabbit Draize test, several protocols using , and skin models are available as internationally harmonized test guidelines. These methods rely on a variety of models of human skin, including excised rodent skin, synthetic biochemical models of barrier function, cell culture systems, and reconstructed human tissue models. We find these models exhibit biological and mechanistic relevance aligned with human skin irritation responses. Further, recent retrospective analyses have shown that the reproducibility of the Draize test is less than 50% for mild and moderate responses, with many of the replicate predictions spanning more than one category (, a moderate response reported in one study followed by a non-irritant response reported in another study). Based on this comparative evaluation, we recommend top-down and bottom-up testing strategies that use the most human relevant test methods for skin irritation and corrosion classification of pesticides and pesticide formulations. To further discriminate among mild and non-irritant formulations, optimization of a cytokine release protocol and subsequent analyses of reference formulation test results is recommended.

: Environmental contamination is a significant global health issue, with cosmetics and pharmaceuticals being major polluters. High concentrations of heavy metals, such as Hg, have been found to have toxic effects and may pose a threat to human health. This study aimed to determine the concentration of mercury (Hg) in lipsticks available in the Saudi Arabia market. : In this study, 12 lipstick samples from three colors were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES) to measure the content of Hg. : The concentration range of Hg was 0.004-0.296 ppm. Moreover, the systemic exposure dosage of mercury in the lipstick samples examined in this study ranged from 5.01 × 10 to 1.43 × 10 μg/kg bw/day, while the range of the margin of safety was from 7.3 × 10 to 2.2 × 10. : The Hg concentration in all analyzed samples was less than 0.50 and 1 ppm, which indicated that the Hg level was within acceptable limits according to Saudi Standards, Metrology and Quality Organisation (SASO) and the United States Food and Drug Administration (US FDA), respectively. On the other hand, the calculated margin of safety values for mercury exceeded the safe standard established by the WHO. The results derived from using hazard quotient (HQ) indices depict the potential carcinogenic health risk posed to consumers who employ red-colored lipsticks.

OBJECTIVE: The widespread use of nanoparticles in recent years has increased the risk of ocular exposure. zinc oxide (ZnO) is widely used in the field of cosmetics because of its unique chemical properties. The application of graphene oxide (GO) as an emerging nanomaterial in the field of eye drops is also gradually emerging. Currently, research on ZnO and GO eye exposure mainly focuses on application or toxicity to optic nerve cells. There's less study on corneal wound healing effects. and the previous research hasn't compared ZnO and GO corneal toxicity. METHODS: We systematically established a complete chain study of in vitro and in vivo experiments and mouse corneal injury model, and comprehensively evaluated the ocular safety and toxicity of ZnO and GO. RESULTS: We found that 50 ug/mL GO and 0.5 ug/mL ZnO can reduce human corneal epithelial cells (HCEpiC) viability in a concentration-dependent manner. Short-term repeated exposure to ZnO can cause sterile inflammation of the cornea with concentration-dependence, while GO have not been significantly altered. 50 ug/mL ZnO could significantly delay the healing of corneal wounds, while GO did not change wound healing. CONCLUSION: The toxic effect of ZnO is higher than that of GO. Inflammatory signal transduction, oxidative stress and apopnano zitosis are involved in the ocular toxicity injury process of nanoparticles. Research can provide a judgement basis for people's eye health and eye protection risk control.

INTRODUCTION: Melanoma is known as a highly lethal cancer. In melanoma cells, apoptosis signalling which relies heavily on the acute activity of mitochondria and reactive oxygen species (ROS) formation is suppressed. Our previous studies on natural compounds on melanoma suggested that mitochondria are a potential target for the melanoma treatment by selective cytotoxic effect of them. The black soldier fly is an important environmental protectant insect that based on recent studies induces apoptosis in liver and colorectal carcinoma cells through the activation of caspase 3, 8, and 9 and ultimately inhibits the growth of cancer cells. PURPOSE: This study was designed to evaluate the selective apoptotic effect of the n-hexane BSFL extract (BSFLE) on skin mitochondria. MATERIALS AND METHODS: The mitochondria isolated from melanoma cells were treated with various concentrations (1500, 3000, and 6000 µg/ml) of n-hexane BSFLE Then MTT viability assay, ROS determination, Mitochondrial Membrane Potential (MMP), mitochondrial swelling, cytochrome c release determination, and % apoptosis were performed. RESULTS: MTT assay showed that different concentrations of n-hexane BSFLE significantly ( < 0.05) decreased the SDH activity in cancerous skin mitochondria with the IC50. The ROS production and mitochondrial swelling results also showed that all concentrations of BSFL extracts significantly increased. MMP decline and the release of cytochrome c in cancer groups mitochondria. BSFLE increased apoptosis on melanoma cells. DISCUSSION AND CONCLUSION: It is suggested that n-hexane BSFLE compounds selectively induce a cascade of proapoptotic events that are probably defective in cancer cells. Most of these compounds target the mitochondrial transient pore caused by disruption of the mitochondrial respiratory chain. These events lead to disruption of the temporary permeability of mitochondria, swelling of mitochondria and finally the formation of apoptosome in the cytosol.

BACKGROUND/ OBJECTIVES: Rosacea is a common chronic inflammatory skin disorder. Endocrinedisrupting chemicals (EDC) are toxic substances, that may gain entry through the skin and subsequently interfere with hormonal and immune functions. Bisphenol A (BPA) and pentachlorophenol sodium (PCS) are two of these EDCs, incriminated in the pathogenesis of certain inflammatory skin disorders. We aimed to test the hypothesis that exposure to BPA and PCS might be involved in the pathogenesis of rosacea. METHODS: This prospective cross-sectional study involved 34 patients with rosacea (18F/16 M; mean age 48.5 ± 11 years) and 34 age and sex-matched healthy controls (20 F/14 M; mean age 48.2 ± 10.2 years). Main anthropometric measures, fasting plasma glucose (FPG), insulin, HOMA-IR, lipids, C-reactive protein (CRP), BPA, and PCS levels were quantified and recorded. RESULTS: Serum CRP (9.6 ± 3.4 vs. 3.7 ± 1.6 mg/L, respectively, p0.05 for all). Serum BPA levels were 55.8 ± 14.4 and 51.9 ± 19.2 ng/mL, and PCS levels were 63.3 ± 45.9 ng/mL and 68.6 ± 40.8 ng/mL for patients and healthy controls, respectively. There was no significant difference in BPA and PCS levels between the two groups ( > 0.05 for both). No significant association was found among HOMAIR, CRP, BPA, and PCS levels ( > 0.05 for all). CONCLUSIONS: Although the present study fails to provide presumptive evidence for the role of BPA and PCS in rosacea, the question as to other EDCs might be involved in its etiopathogenesis remains. This hypothesis requires confirmation in large-scale future prospective trials.

OBJECTIVE: Hidradenitis suppurativa (HS), a chronic inflammatory disease that typically manifests after puberty, is characterised by painful nodules, abscesses, draining sinus tracts, and scars in areas rich in apocrine glands such as the axillary and inguinal regions. In recent years, blood-based biomarkers such as the Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR), Monocyte/Lymphocyte Ratio (MLR), Mean Platelet Volume (MPV), Systemic Immune-Inflammation Index (SII) and Pan-Immune-Inflammation Value (PIV) have been used as significant indicators of systemic inflammation. While there are few studies evaluating these biomarkers in HS, the response of these markers to treatment has only been assessed in one study to date. Our study aims to investigate the effect of adalimumab treatment on blood-based systemic inflammation biomarkers in HS, where inflammation plays a significant role. METHODS: The study included 42 adult patients who received adalimumab treatment at our dermatology and venereology clinic between January 2020 and January 2023. Medical records for complete blood count results of the patients were retrospectively reviewed. All systemic inflammation-based biomarkers were calculated from the absolute values of the complete blood count. The SII was calculated with the following formula: (neutrophil count × platelet count/lymphocyte count). The PIV was calculated as follows: (neutrophil count × platelet count × monocyte count/lymphocyte count). Values before the treatment and at the 12th week of treatment were compared. RESULTS: When the changes in the inflammatory parameters of the patients were examined, it was found that NLR (2.13 ± 0.87 vs 2.26 ± 1.12), PLR (111.01 ± 39.89 vs 99.43 ± 35.34), MLR (0.27 ± 0.11 vs 0.28 ± 0.12), MPV (9.59 ± 0.71 vs 9.70 ± 0.79), SII (680.79 ± 330.18 vs 687.89 ± 442.66), and PIV (552.02 ± 330.71 vs 605.05 ± 415.96) values did not change statistically significantly after treatment (p > 0.05). While there was a significant decrease in platelet count compared to before treatment, no statistically significant difference was found in the other evaluated blood cells. CONCLUSION: Adalimumab treatment has not had a significant effect on systemic inflammation markers in HS, an inflammatory disease. More studies are needed to evaluate the effect of adalimumab on these markers in HS.

PURPOSE: To evaluate the safety and tolerability of pooled human immune globulins, Flebogamma 5% DIF and Flebogamma 10% DIF, administered by topical ophthalmic instillation to New Zealand White (NZW) rabbits. METHODS: Male NZW rabbits were used in this study. In the acute single dose tolerability study, rabbits (n = 12) received a single topical dose of Flebogamma 5% DIF. In the two-week repeated-dose tolerability study, rabbits (n = 5 for each group) were administered either Flebogamma 5% DIF or Flebogamma 10% DIF by topical bilateral administration four times daily (q.i.d.) between 8 am and 6 pm for a period of two weeks. Full ophthalmic examinations were conducted to evaluate ocular tolerability at baseline, Day 7, and Day 14. RESULTS: In the acute single dose study, mild hyperaemia was observed in 1 out of 4 eyes at each 4 h and 24 h post-instillation of Flebogamma 5% DIF. In the repeated dose study, no ocular signs were detected after q.i.d. topical instillation of Flebogamma 5% DIF, while Flebogamma 10% DIF resulted in mild hyperaemia in 8 out of 10 eyes on Day 7, and 5 out of 10 eyes on Day 14. No positive corneal fluorescein staining was detected. Schirmer tear test results were unremarkable. No other ocular signs were observed. Administration of immune globulins had no effect on intraocular pressure. CONCLUSIONS: Flebogamma 5% DIF and Flebogamma 10% DIF were well-tolerated by NZW rabbits following single and repeat dose topical ophthalmic administration, supporting the future development of topical pooled human immune globulins for the treatment of ocular surface disease.

PURPOSE: This study aims to examine and compare the effects of intravitreal bevacizumab injection (IVB) at subfoveal 1500 micron (μm) and submacular 6000 μm in patients with diabetic macular edema (DME). METHODS: Fifty eyes of 45 patients with DME who completed six doses of IVB were included in the study group, and 50 eyes of 42 patients who had diabetic retinopathy (DR) but did not receive any treatment were included in the control group. Central macular thickness (CMT), central choroidal thickness (CCT), subfoveal and total choroidal area (TCA), and choroidal vascular index (CVI) were calculated and their changes at zero, three and six months were evaluated. RESULTS: At baseline, CVI was significantly lower in both the subfoveal and total macular areas in the study group ( = 0.004, = 0.003). In the study group, a significant decrease was observed in CVI between zero and six months in the subfoveal area ( = 0.001). In the submacular area, the decrease in CVI in the study group was significant between zero to three months and zero to six months. There was moderate correlation between measurements of CVI in the subfoveal and total macular areas ( = 0.66, < 0.001). CONCLUSION: These findings indicate that intravitreal bevacizumab injection reduces the CVI and the effects of intravitreal anti-VEGF on CVI emerge earlier and more prominently in the submacular 6000 µm area.

The process of skin ageing is a natural biological phenomenon characterised by the emergence of wrinkles, age spots, sagging skin, and dryness over time. The increasing significance of skin in physical attractiveness has heightened skincare concerns. Anti-ageing cosmetics play a pivotal role in nurturing the skin, enhancing its quality, and promoting overall health. Today, cosmetics have evolved beyond mere aesthetics and are now integral to individual wellness. The contemporary quest for perpetual youth has intensified, prompting a deeper exploration into the skin ageing process. This comprehensive exploration delves into various elements involved in skin ageing, encompassing cells such as stem and endothelial cells, blood vessels, soft tissues, and signalling pathways. The molecular basis of skin ageing, including biochemical factors like reactive oxygen species, damaged DNA, free radicals, ions, and proteins (mRNA), is scrutinised alongside relevant animal models. The article critically analyzes the outcomes of utilising herbal components, emphasising their advantageous anti-ageing properties. The factors contributing to skin ageing, mechanistic perspectives, management approaches involving herbal cosmeceutical, and associated complications (especially cardiovascular diseases, Parkinson's, Alzheimer's, etc.) are succinctly addressed. In addition, the manuscript further summarises the recent patented innovations and toxicity of the herbal cosmeceuticals for anti-ageing and ageing associated disorders. Despite progress, further research is imperative to unlock the full potential of herbal components as anti-ageing agents.

OBJECTIVE: Miltefosine stands as the sole oral medication approved for the treatment of leishmaniasis. The appearance of severe ophthalmic toxicities induced by miltefosine in the context of leishmaniasis treatment is a matter of significant concern. The main objective of this study is to present a comprehensive summary of the ophthalmic adverse effects associated with miltefosine when used in the treatment of leishmaniasis. METHODS: A systematic search was performed on PubMed, ScienceDirect, Embase, Scopus, and Google Scholar, covering articles from inception up to June 2023, without language restrictions, to identify relevant studies documenting ocular toxicity following miltefosine treatment for leishmaniasis. RESULTS: A total of eight studies involving 31 leishmaniasis patients who developed ocular toxicities while undergoing miltefosine treatment were included in the analysis. These studies were conducted in various regions, with five originating from India, two from Bangladesh, and one from Nepal. Patients presented a spectrum of ophthalmic complications, including uveitis, keratitis, scleritis, and Mooren's ulcer. Commonly reported symptoms included pain, redness, excessive tearing, partial vision impairment, permanent blindness, light sensitivity, and the appearance of white spots on the eye. On average, patients received miltefosine treatment for a duration of 47 days before experiencing the onset of ocular problems. It is important to note that the risk of ocular toxicities increases with prolonged use of miltefosine. CONCLUSIONS: Therefore, to mitigate the potential for irreversible damage to the eyes, it is imperative that all individuals undergoing miltefosine therapy undergo regular eye examinations.

PURPOSE: To investigate the effects of topically applied 1% tropicamide, 2.5% phenylephrine and 1% cyclopentolate on retinal vessel calliper (VC) using optical coherence tomography (OCT). METHODS: Patients who came to the ophthalmology clinic for routine examination and whose OCT films were taken before dilatation and after 30 min of last dilatation drop were included in the study. 90 ophthalmologically healthy subjects were divided into 3 groups of 30 subject each according to the application of the drops as follows: Tropicamide group (Group 1), Phenylephrine group (Group 2), Cyclopentolate group (Group 3). The right eyes of the subjects were dilated with drops and the left eyes were taken as the control group. VC of retinal artery and vein passing through an area one-half to one-disc diameter from the optic disc margin were measured from OCT films. The mean of the sum of superior retinal artery (SRA) and inferior retinal artery (IRA) VC and the mean of the sum of superior retinal vein (SRV) and inferior retinal vein (IRV) VC before and after the drop were compared. RESULTS: There was no statistically significant change in the mean sum of SRA and IRA VC and the mean sum of SRV and IRV VC before and after dilatation drops in all three groups. CONCLUSION: Dilatation drops have no statistically significant effect on retinal artery and vein VC.

AIM: There is no marker that can predict whether there is resistance to treatment in patients with psoriasis. In this study, we investigated the relationship between the staining rates of TNF-α, IL-1, IL-12, IL-17, IL-23, and IL-36 markers immunohistochemically from cutaneous biopsy and the treatment success. METHODS: The patients who were followed up in the dermatology clinic with the diagnosis of plaque-type psoriasis vulgaris and received biological treatment and previously had cutaneous biopsy were included in the study. The cutaneous biopsies of the cases that met the conditions were re-sectioned and subjected to immunohistochemical examination for TNF-α, IL-1, IL-12, IL-17, IL-23, and IL-36. RESULTS: Comparing the staining scores with psoriasis area severity index (PASI); A statistically significant positive correlation was found between PASI and TNF-α staining score ( = 0.034). A statistically significant positive correlation was found between PASI and IL-17 staining score ( = 0.004). When the staining scores and PASI response rates of psoriasis treatment were evaluated in terms of correlation; there was a positive correlation between TNF-α, IL-17, and IL-23 immunohistochemical staining rates and PASI response rates. CONCLUSIONS: In line with the data obtained from our study, we think that making immunohistochemical scoring before the biological treatment decision in psoriasis patients will be beneficial in treatment selection. In this respect, our study may open a new era in the selection of biological treatments for psoriasis.

PURPOSE: The study aims to investigate changes in tear function, meibomian glands and corneal endothelium in patients receiving systemic isotretinoin therapy. MATERIALS AND METHODS: This prospective study included 38 eyes from 38 patients (23 females and 15 males) treated with systemic isotretinoin (0.5-1 mg/kg/day) following the diagnosis of acne vulgaris. All patients underwent a comprehensive ophthalmologic examination at baseline, 1st month, and third month of treatment. Subjective complaints were assessed using the Ocular Surface Disease Index (OSDI). Tear functions were evaluated through non-invasive tear break up time (NIBUT) and Schirmer I test. Meibomian gland (MG) changes were examined using meibography. Corneal parameters, including endothelial cell density (ECD), coefficient of variation (CV), the number of cells with a hexagonal shape (6A), average cell area (AVG), and central corneal thickness (CCT) were assessed using non-contact specular microscopy. RESULTS: The mean age of the patients was 19.29 ± 2.83 years. Ocular surface-related discomfort, measured with OSDI scores, significantly worsened at the third month measurements compared to the pre-treatment values ( < 0.001). In the 1st month of treatment, there was a significant decrease in NIBUT ( < 0.05). No statistically significant difference was found in the Schirmer test results at each visit. According to the 1st and third-month analysis, there was a significant increase in MG loss compared to the pre-treatment period ( < 0.001). ECD, CV, 6 A, AVG measurements at the first and third months showed a significant change compared to the pre-treatment values ( < 0.001). No significant difference was observed in the CCT measurements during the treatment. CONCLUSION: Systemic isotretinoin disrupted tear stability, caused MG loss, deterioration in corneal endothelium, and led to symptomatic complaints in patients.

OBJECTIVE: Prototype cosmetic formulations containing short-chain acids and alcohols intended to be applied in the proximity of the eyes are sometimes evaluated for ocular irritation potential using the validated Bovine Corneal Opacity and Permeability Assay (OECD TG 437). We evaluated the eye irritation potential of nine experimental cosmetic formulations designed and prepared by Avon Global Reserach and Development to differ only in the concentrations of Ethanol, Glycolic Acid and Salicylic Acid. METHODS: We analysed the data generated using the BCOP assay. The opacity and permeability values obtained following the exposure of bovine corneas to experimental cosmetic formulations were combined into a single Irritancy Score used to rank eye irritation potential. Histopathological examination of treated corneas was used to provide additional information about the depth and degree of the injury and to support the prediction of eye irritation potential of each experimental cosmetic formulation. RESULTS: The Irritancy Scores and histopathological analysis showed that experimental formulations containing only Ethanol, Glycolic Acid, or Salicylic Acid alone had, at most, a mild ocular irritation potential. The experimental formulations containing both Ethanol and Glycolic Acid had a mild ocular irritation potential, while the experimental formulations containing both Ethanol and Salicylic Acid had a moderate ocular irritation potential. Severe ocular irritation potential was induced by an experimental formulation containing a combination of Glycolic Acid and Salicylic Acid and it was further accentuated by the addition of Ethanol to the formulation. Our data indicate a possible synergistic effect on eye irritation potential of Ethanol, Glycolic Acid and Salicylic Acid in at least some experimental cosmetic formulations. Further, our results provide insight on an apparent concentration-dependent ocular irritation potential effect of combinations of Glycolic Acid, Salicylic Acid and Ethanol in at least one experimental cosmetic formulation. CONCLUSIONS: The results presented herein emphasise the need to consider testing of prototype cosmetic formulations containing combinations of Ethanol, Glycolic Acid and Salicylic Acid rather than relying on any predicted additive effect on ocular irritation based solely on previously generated results of similar formulations containing Ethanol, Glycolic Acid or Salicylic Acid alone. Further work is required to understand the significance of these observations and to elucidate the mechanisms responsible for the apparent synergistic effects of Glycolic Acid, Salicylic Acid and Ethanol and eye irritation potential suggested by our results.

PURPOSE: Psoriasis, affecting approximately 2% of the world's population, often necessitates systemic treatments, with methotrexate (MTX) as a cornerstone therapy. Despite documented systemic side effects of MTX, concerns about its impact on male reproductive health persist. We aim to investigate low-dose MTX effect on hormonal, cellular and functional ability of male reproductive system. MATERIALS AND METHODS: Our prospective study on 40 male psoriasis patients receiving low-dose MTX (<15mg/week) comprehensively investigates its effects on erectile function, sex hormones, and spermiogram parameters. RESULTS: After six months of MTX treatment, a significant decline in erectile function ( < 0.001) decreased total testosterone levels (p = 0.03) were observed. No significant reduction in sperm count was noted after six months of MTX treatment. CONCLUSIONS: Our study highlights a significant decline in erectile function following low-dose MTX therapy, warranting further investigation into this potential side effect. While reassuring for sperm quantity and quality, the findings emphasise the necessity for larger cohorts and longer follow-up times to validate results and comprehend the complex interactions between MTX and male sexual health.

OBJECTIVE: To study the ocular effects seen among eye cosmetic wearers in the Indian Population. METHODS: This cross-sectional study was conducted on female participants who had fulfilled the inclusion and exclusion criteria. A detailed history was obtained and thorough ophthalmic evaluation was done. Mann Whitney test was used. Statistical analysis was done using IBM SPSS. < .05 was taken as the level of statistical significance. RESULTS: Among a total of 225 participants in our study, the mean age was 24.23 ± 1.8, which comprised of young student females. Majority of the females used one eye cosmetic with Kajal ( = 156) being the most predominant. Most frequently encountered symptom upon using eye cosmetics was watering from eyes and ocular pain was the least encountered symptom. Anterior segment examination showed- allergic conjunctivitis and meibomian gland dysfunction being the most and least predominant, respectively. Our study highlights that Kajal predisposes the eyes to significant ocular morbidity with = .039 for dry eye disease, = .041 for allergic conjunctivitis, = .036 for conjunctival pigmentation. Prolonged use of such formulations for more than 4 times a week ( = .046) or even daily ( = .031) for a duration of either 1-5 years ( = .033) or greater than 5 years ( = .027) was found to be statistically significant in causing ocular signs. Non removal of eye cosmetics at the end of the day was significant in causing allergic conjunctivitis ( = .035) and conjunctival pigmentation ( = .021). Plain tap water has been found to be the least effective technique in the removal of such ocular cosmetics with a statistical significance of = .031 in causing ocular signs. CONCLUSIONS: Eye cosmetics are a significant contributor to the development of ocular surface diseases. Removal of products along with decreased usage seems to be a significant contributor in dampening unwanted adverse effects.
