Abstract

The goal of an antiseptic is to eliminate or greatly reduce the number of microorganisms in the surgical field at the time of the surgery. The objective of this study was to verify the effectiveness of 20% Piper betle leaf infusion as an antiseptic solution in pre-surgery cataract patients. A clinical trial with partner-matching design was conducted on 31 pairs of eyelids. From each pair of eyelids, one eyelid was asigned to the Piper betle infusion group and the opposite one to the povidone-iodine group. The microorganisms were collected by swab from the patient’s palpebral skin, inoculated on nutrient agar, and incubated at 37oC for 20 hours. The antiseptic effectiveness was measured by counting the microbial colonies before and after administration of the antiseptic solutions. This study demonstrates that the mean colony counts after application of 20% Piper betle leaf infusion showed a significant reduction of 27-100% compared with those before administration (p=0.001). Mean colony counts after 10% povidone-iodine administration showed a significant reduction of 88-100% compared with the mean counts before the solution was applied (p=0.000). The 20% Piper betle infusion has an antiseptic potential. Nevertheless, the 10% povidone-iodine solution has more effective antiseptic capability.

Abstract

Introduction: HLA-B27 is a genetic marker strongly associated with spondyloarthropathy (SpA) and acute anterior uveitis (AAU). Detection of this allele can support earlier diagnosis and targeted management. However, commercially available HLA-B27 tests are costly and often inaccessible in low- and middle-income countries, including Indonesia. Methods: A cross-sectional study was conducted involving 42 subjects: 14 with SpA, 19 with AAU, and 9 healthy controls. DNA was extracted from peripheral blood samples and analyzed using both conventional PCR (targeting exon 3 of HLA-B27) and a commercial HLA-B27 strip assay. Sensitivity, specificity, and diagnostic accuracy of conventional PCR were calculated against the commercial kit as the reference standard. Results: Conventional PCR showed high sensitivity (100%) and accuracy (85.71%) in SpA patients, indicating its potential as a reliable screening tool in this group. However, its performance in AAU patients was suboptimal, with lower sensitivity (40%) and specificity (55.56%). False positives and false negatives were observed, likely due to limitations in allele coverage by conventional primers. Conclusion: Conventional PCR is a promising, affordable alternative for HLA-B27 detection in SpA patients, particularly in resource-limited settings. However, its lower reliability in AAU cases highlights the need for careful clinical application and further optimization. Larger studies and local allele mapping are recommended to enhance diagnostic precision in diverse populations.

Abstract

Background: Keratomycosis, a fungal corneal infection prevalent in tropical regions, frequently leads to visual impairment and blindness. Liposomal amphotericin B (L-AmB) offers improved efficacy and reduced toxicity compared to conventional amphotericin B deoxycholate and represents a promising option for topical ophthalmic use. Objective: To evaluate and compare the therapeutic efficacy of L-AmB eye drops at 0.15% and 0.5% concentrations in experimental Aspergillus keratomycosis in New Zealand White rabbits. Methods: Four rabbits received midstromal corneal inoculation with a mixed suspension of Aspergillus flavus, A. fumigatus, A. niger, and A. terreus (2 x 10⁴ CFU/0.05 mL). L-AmB eye drops were applied hourly from day 8 post-inoculation until corneal cultures became negative. Antifungal susceptibility was assessed by disc diffusion. Clinical response was monitored by slit lamp examination using a modified scoring system. Results: Negative corneal cultures were achieved in all treated eyes within 10 to 18 days (mean 15 days, L-AmB 0.15%) and 11 to 15 days (mean 14 days, L-AmB 0.5%). No toxic effects were observed. Complete corneal transparency without cicatrix was achieved in one eye treated with L-AmB 0.15%. Conclusion: Both concentrations were effective and safe. Liposomal AmB 0.15% appears as efficacious as 0.5% for experimental Aspergillus keratomycosis. Clinical studies in humans are warranted.
