Blind navigation is an accessibility application that enables blind to use an android Smartphone in an easy way for indoor navigation with instructions in audio form. We have proposed a prototype which is an indoor navigation application for blinds that uses QR codes. It is developed for android Smart phones and does not require any additional hardware for navigation. It provides automatic navigational assistance on pre-defined paths for blind. QR codes are placed on the floor sections after specific distance that acts as an input for current location detection and navigation. Whenever a QR code is scanned it provides the user with the information of the current location and asks the user to select the destination and then offers optimal and shortest path using path finding algorithms. During navigation whenever the deviation from the proposed path is detected it prompts the user and guides back to the right path by comparing the current path with the generated path. All of the instructions throughout the application are provided in audio form to the user. The interface of the application is well built for blinds which makes the smart phones user-friendly and useable for blind people. The user interacts with the application through a specific set of user-friendly gestures for specific inputs and operations. At the end, we have performed comparison between different state of art approaches and concluded that our approach is more user friendly, cost effective and produced more accurate results.
Endometrial stromal sarcoma is rare gynecological malignancy. A proper preoperative diagnosis is difficult and most of cases diagnosed on histopathology. This is case of endometrial stromal sarcoma infiltrating to both ovaries that is stage II A.A 44year old female presented with complaint of irregular heavy vaginal bleeding and history of loss of weight, appetite and altered bowel habits. Clinical diagnosis of Leiomyosarcoma was in mind but on histopathology endometrial stromal sarcoma infiltrating to both ovaries confirmed.
Objective: To evaluate our experience in treatment of Caesarean Scar Pregnancy (CSP). Study Design: Cross Sectional Descriptive study. Setting: Department of Gynecology and Obstetrics, Independent Medical College Faisalabad. Period: Jan 2016 to Jan 2021. Material & Methods: The data for this study retrospectively obtained from outpatient department, emergency ward and labor ward registers. Data was analyzed by simple descriptive statics. Diagnosis of CSP was made by using transvaginal ultrasound and color flow Doppler ultrasound. Treatment offered was either medical management as systemic methotrexate or surgical as D&C or laparotomy. The aim was to do conservative treatment for fertility sparing. Patient age, gestational age at time of presentation, number of previous Cesarean Section and success of overall management strategy was analyzed. Results: In this study we had 12 patients diagnosed to have CSP with at least one scar on uterus of previous caesarean section. The mean age of patients was 32.5± 2 years and the gestational age range was from 5 weeks and 3 days to 10 weeks and 1 day. The diagnosis was done by using transvaginal ultrasound and color flow Doppler ultrasound. Which showed high velocity and low impedance flow in sub trophoblastic area. Out of 12 patient’s 58.33 percent were treated with systemic methotrexate and had successful outcome. These were followed by B-hCG levels till non pregnant serum level of B-hCG of <5.1IU was achieved. 16.66 percent patients underwent D&C, but due to hemorrhage they were treated with laparotomy as supplementary procedure. 41.55 percent Patients were treated by laparotomy as their primary management with aim of fertility sparing surgery. The laparotomy was found to be successful treatment in all the patients who underwent surgical management as their primary treatment. Conclusion: Prompt diagnosis has pivotal role in reducing morbidity and mortality associated with CSP. Medical management is found to be successful at early gestational age. Fertility sparing surgery is better option as gestation advances more than 8 weeks to avoid undesirable outcome like hemorrhage and hysterectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
