Methods: Sixty-eight primary pterygium participants were selected from patients who visited an ophthalmology clinic. We developed a semi-automated computer program to measure the pterygium fibrovascular redness from digital pterygium images. The outcome of this software is a continuous scale grading of 1 (minimum redness) to 3 (maximum redness). The region of interest (ROI) was selected manually using the software. Reliability was determined by repeat grading of all 68 images and its association with contrast sensitivity function (CSF) and visual acuity (VA) was examined. Results: The mean and standard deviation of redness of the pterygium fibrovascular images was 1.88 ± 0...

The internet enables quick feedback from the experts at the comfort of their home of office. In this study, we demonstrated the use of online form as a tool to get quick feedback from clinicians on clinical grading of pterygium images with various severities. The scores were analyzed using quartile analysis and the median was used to construct the benchmark scores for the images. This dataset was tested on assessing human grader and was later fitted with neural network to measure the performance of the machine learning algorithm.

Psoriasis, is a genetically determined chronic inflammatory dermatosis immuno disorder associated with over expression of proinflammatory cytokines characterized by red, scaly and raised patches that affects 2.3% of the population worldwide. According to American academy of dermatology, antibacterial therapy could also be used for treating psoriasis. In view of this, the present investigation was carried out to study the antibacterial activity with respect to their traditional use as antipsoriatic agents. The powdered bark was successively extracted with ethyl acetate and methanol and subjected to preliminary phytochemical analysis and HPTLC finger print analysis. The antimicrobial studies of ethyl acetate and methanol extract was carried out by agar diffusion method. Among the ethyl acetate and methanol extract, methanol extract exhibited highest zone of inhibition at the concentration of 1000 ppm against Staphyloccocus aureus (18 mm) which has been one of the organisms which aggravate conditions like psoriasis, while moderate activity against Streptococcus pyogenes (12 mm). The zone of inhibition of ethyl acetate extract against Escherichia coli was 11 mm and against Streptococcus pyogenes was 14 mm at higher concentration (1000 ppm). The methanolic extract was ineffective against the fungal strain Candida albicans and ethyl acetate extract exhibited moderate effect (11 mm) against fungal strain at higher concentration (1000ppm). The minimum inhibitory concentration was also determined and found that the methanolic extract was required in relatively lesser quantities for arresting the growth of the tested organisms. The results obtained may provide validation for its reported medicinal uses.

Egg masses in tap water were individually placed between the tips of needle electrodes 1 mm apart and exposed to potentials of l, 10, 20, and 60 vdc/mm at 1, 1, 1, and 86 milliamperes dc, respectively, for periods of 2 and 60 seconds. Hatched larvae were counted at five-day intervals for 60 days. Of the eight treatment combinations used, six gave a greater egg hatch than the control. The largest hatch, 520 percent greater than the control, resulted from exposure to 1 vdc/mm for 60 seconds; 60 vdc/mm for 2 and 60 sec decreased egg hatch 11 and 94 percent of the untreated control. Hatched larvae from all treatments except the 60 vdc/mm, 60-second exposure were infective and reproduced on young cotton plants in a glasshouse.

We describe the case of a 35-year-old male with bilateral adrenal masses which turned out to be histoplasmosis on biopsy, so the masses were treated with antifungal agents. We describe the case for its rarity.
