Method: This study was performed on 44 eyes of 22 patients. All patients were above 18 years old and had no ocular and systemic problems apart from refractive error. Detailed evaluation was done for refractive surgery. The method of epithelial removal was randomly assigned. Patients were postoperatively evaluated for comfort in terms of pain, watering, foreign body sensation (FB) and photophobia with the help of questionnaire based Performa on day 0,5, 15 and 60. Results: A total of 44 eyes of 22 patients were evaluated. Mean scores were higher in mechanical debridement eyes than alcohol-assisted eyes in day 0 and day 5. Pain and FB sensation had a significant difference on day 5 whereas watering and photophobia had a significant difference on day 0. Conclusion: In terms of patient's comfort (pain, FB sensation, watering and photophobia) alcohol-assisted removal seems to be a better option.

It is a noninvasive form of therapy that both resolves urinary symptoms and corrects the underlying disorder, in hopes of achieving long-term cure. Pelvic floor therapy is a teaching tool that helps to correct the “dysfunction” of voiding with a success rate ranging from 80 to 95% in improving incontinence. It also decreases recurrent urinary tract infections and decreases the need for surgical intervention for vesicoureteral reflux. Biofeedback therapy can also be used in conjunction with other types of treatment such as behavior modifications, medication, and/or surgical correction. In pediatric urology, its primary role is in treating and improving the neurologically normal group of children with evidence of dysfunctional voiding.

Materials and Methods: A retrospective review of 809 laparoscopic explorations for nonpalpable testes between 1981 and 2003 was conducted. The histological findings of the excised remnants of those patients with a closed processus vaginalis were reviewed. Results: A total of 110 patients underwent excision of a testicular remnant at inguinal exploration in association with a closed processus vaginalis. Of the specimens 31 (28%) were on the right side and 79 (72%) were on the left side. The incidence of viable germ cell elements was 8 of 110 (7%). The presence of hemosiderin, calcification and fibrosis was identified in all 8 remnants with viable germ cell elements. Conclusions: The incidence of viable germ cell elements in the excised remnant when the vas deferens and spermatic vessels are identified exiting a closed internal ring in patients with a nonpalpable testis is 7%. To our knowledge no prior study has evaluated the incidence of viable germ cell elements in remnants associated with a closed internal inguinal ring. Based on these findings, we advocate inguinal exploration and excision of testicular remnants in these patients.

In this work, a multi-emergency management system based on a single step, non-cooperative, normal form game model, and a Nash equilibrium based optimization methodology is proposed. In the proposed system, each emergency event is represented as a player in the game, who is competing with other players for the allocation of resource units that are available in limited quantities within a given urban perimeter. The Nash equilibrium based methodology identifies a socially fair allocation of resources depending on various fairness criteria like the demand by each emergency event, and the criticality of the events. The fairness criterion is well modeled in the game theoretic setting, while the criticality of an event can be modeled as per the requirements of a specific emergency management system. Such a system will be useful in managing emergencies in small to medium urban settings. The proposed game theoretic methodology naturally models the emergency response and resource deployment problem in the framework of social fairness, which is pivotal in these scenarios. The Nash equilibrium solution is computed using the Terje Hansen's fixed-point algorithm. Experimental results are presented for various test cases and metrics are developed to establish the quantitative measure of fairness of the results. The proposed system can be used as a decision support tool for managing emergencies, or as a simulator for learning and training purposes.
