Comparative Effects of Azithromycin and Probiotics for Treatment of Acne Vulgaris.

OBJECTIVES: To measure the efficacy of oral probiotics when combined with a topical agent, and to compare the efficacy of Azithromycin, Probiotics, and their combination for the treatment of acne vulgaris. STUDY DESIGN: A quasi-experimental study. Place and Duration of the Study: Pharmacology Department, IIMC in mutual collaboration with the Dermatology Department, Pak Emirates Military Hospital (PEMH), Rawalpindi, from September 2021 to August 2022. METHODOLOGY: Seventy-five patients were enrolled in the study and were divided into 3 groups. Group A received Azithromycin (250mg oral on alternate days), Group B received probiotics i.e. Hi-Flora sachet (1 sachet oral daily), and Group C received both azithromycin (250mg oral on alternate days) and probiotics (Hi-Flora 1 sachet oral daily). The efficacy of three treatment regimens was measured by checking the difference in mean lesion count at the baseline and after 3 months of treatment and the percentage was calculated. RESULTS: All patients demonstrated significant improvement in total lesion count after treatment. In group A, the mean lesion count was reduced by 83.3%, in group B by 84.4%, and in group C, the reduction in mean lesion count was 90.3%. CONCLUSION: Probiotics have equal efficacy to azithromycin, and their combination has shown synergistic effects for the treatment of acne vulgaris. Probiotics should be used in combination with azithromycin for the best results for the management of acne vulgaris. KEY WORDS: Acne vulgaris, Azithromycin, Probiotics, Efficacy.

Efficacy of Autoinoculation in Treatment of Multiple Viral Warts - A Single Arm Study.

OBJECTIVE: To test the effectiveness of autoinoculation of a wart in patients with multiple viral warts. STUDY DESIGN: An experimental study. PLACE AND DURATION OF STUDY: Department of Dermatology, Pak Emirates Military Hospital (PEMH), Rawalpindi, from February 2021 to February 2022. METHODOLOGY: Patients above 12 years of age, having more than 5 warts were included. Those getting any other treatment for warts were excluded. The procedure was performed on a total of 70 patients with warts on 3 sites i.e. face/neck, palmoplantar and multiple sites. The outcome was categorised into cleared (no wart), partially cleared (reduced number of warts than baseline), and no response (same or increased number of warts than baseline). RESULTS: Out of 70 patients, 54 (77.1%) patients showed complete response, 6 (8.6%) showed partial response and 10 (14.3%) showed no response at all. Out of 54 patients who showed complete response, 36 (66.6%) were cleared after only one inoculation, fifteen (27.7%) were cleared after two inoculations, and 3 (5.5%) were cleared after three inoculations. The results were statistically significant with p-value <0.05. CONCLUSION: Autoinoculation is a simple and minimally invasive procedure which proved to be very effective against all types of warts, with very promising results against palmoplantar warts.

An image retrieval approach to setup difficulty levels in training systems for endomicroscopy diagnosis.

Learning medical image interpretation is an evolutive process that requires modular training systems, from non-expert to expert users. Our study aims at developing such a system for endomicroscopy diagnosis. It uses a difficulty predictor to try and shorten the physician learning curve. As the understanding of video diagnosis is driven by visual similarities, we propose a content-based video retrieval approach to estimate the level of interpretation difficulty. The performance of our retrieval method is compared with several state of the art methods, and its genericity is demonstrated with two different clinical databases, on the Barrett's Esophagus and on colonic polyps. From our retrieval results, we learn a difficulty predictor against a ground truth given by the percentage of false diagnoses among several physicians. Our experiments show that, although our datasets are not large enough to test for statistical significance, there is a noticeable relationship between our retrieval-based difficulty estimation and the difficulty experienced by the physicians.
