Incidence of Penile Fracture in Iran, a Cross-Sectional Study

Background: Penile fracture is a urological emergency requiring proper diagnosis and treatment. Limited studies conducted in Iran have reported high prevalence of this problem (9.9 per 100,000 male population). In this study, we also examined the causes and symptoms, as well as the type of treatment physicians choose so that in the future, we can use this data to educate physicians and other people in the community about this disease. Methods: First, all urologists across the country were contacted and informed about the project. Then, from February 2017 to February 2018, a pre-prepared questionnaire containing the required information was sent to them and they were asked to complete and send this questionnaire in case of a penile fracture. Then, every two weeks, we reconnected all urologists in different ways (email, phone call, virtual networks, etc.) and collected relevant data. Finally, all data were analyzed using SPSS software, version 19.  Results: The incidence of penile fractures was estimated to be 2.5 per 100,000 men (from 0.38 in the age range of 69-60 years to 3.9 in the age range of 39-30 years). The most common causes of penile fractures were sexual intercourse (64.8%), followed by non-sexual trauma (16.9%) and masturbation (13.3%). Pain, edema and discoloration of the penis were the most common symptoms at the time of admission (83.6%) and most patients (84%) had referred to a physician within the first 24 hours after the accident. 78.9% of urologists believed in emergency surgical treatment, while 20.3% believed in delayed surgical treatment and 0.7% believed in supportive treatment. Conclusion: Because of the cultural diversity of Iran, the rate of penile fracture is very different in different parts of Iran, but its rate is much lower than previous studies

A Mobile Geo-Communication Dataset for Physiology-Aware DASH in Rural Ambulance Transport

Use of telecommunication technologies for remote, continuous monitoring of patients can enhance effectiveness of emergency ambulance care during transport from rural areas to a regional center hospital. However, the communication along the various routes in rural areas may have wide bandwidth ranges from 2G to 4G; some regions may have only lower satellite bandwidth available. Bandwidth fluctuation together with real-time communication of various clinical multimedia pose a major challenge during rural patient ambulance transport.; AB@The availability of a pre-transport route-dependent communication bandwidth database is an important resource in remote monitoring and clinical multimedia transmission in rural ambulance transport. Here, we present a geo-communication dataset from extensive profiling of 4 major US mobile carriers in Illinois, from the rural location of Hoopeston to the central referral hospital center at Urbana. In collaboration with Carle Foundation Hospital, we developed a profiler, and collected various geographical and communication traces for realistic emergency rural ambulance transport scenarios. Our dataset is to support our ongoing work of proposing "physiology-aware DASH", which is particularly useful for adaptive remote monitoring of critically ill patients in emergency rural ambulance transport. It provides insights on ensuring higher Quality of Service (QoS) for most critical clinical multimedia in response to changes in patients' physiological states and bandwidth conditions. Our dataset is available online for research community.Comment: Proceedings of the 8th ACM on Multimedia Systems Conference (MMSys'17), Pages 158-163, Taipei, Taiwan, June 20 - 23, 201

Tunability of terahertz random lasers with temperature based on superconducting materials

We theoretically demonstrate the tunabiltiy of terahertz random lasers composed of high temperature superconductorYBCO and ruby layers as active medium. The considered system is a one-dimensional disordered medium made of ruby grain and YBCO. Finite-difference time domain method is used to calculate the emission spectrum and spatial distribution of electric field at different temperatures. Our numerical results reveal that the superconductor based random lasers exhibit large temperature tunability in the terahertz domain. The emission spectrum is significantly temperature dependent, the number of lasing modes and their intensities increase with decreasing temperature. Also, we make some discussion to explain the reason for the observed tunability and the effect of temperature variation on the spatial distribution of the electric field in the disordered active medium
