Till-date research in communications industry has mainly focused on systems based on electromagnetic propagation. However, in nanotechnology the scales are very minute, hence it needs further research that whether these concepts apply or not. So far, molecular communications research has studied the propagation of individual molecules between closely spaced transmitters and receivers as embedded in a fluid medium. Using these concepts, scientists are now investigating into nanomachines, nanomedicines, nanorobotics, and bio-chips which have enabled to further the computer science communications with biologically inspired algorithms. If timely parallels can be drawn between molecular communications and electrical communications there is potential for cross-learning and an opportunity to pioneer new developments. This paper aims to bring forth the key principles in molecular communication and their relationship to electrical communications as out-of-the-box philosophy for academicians and students.

A 27-year-old woman presented 6 weeks after an uncomplicated lower segment caesarean section with excessive bleeding per vagina. On examination, she had mild pallor with a pulse rate of 86 beats per minute and blood pressure of 116/80 mm Hg, uterus well involuted with closed cervical os and bleeding demonstrated through the cervix. A transvaginal ultrasonography with colour Doppler revealed a normal size uterus with an empty cavity and a hypoechoic area with blood flow within it in the left side of the uterus with a prominent arterial feeder vessel. A CT angiogram confirmed the diagnosis of a 1.3×0.7 cm pseudoaneurysm of the uterine artery near the left cornua of the uterus. After failed attempts to control the bleeding with antifibrinolytics, bilateral uterine arteries were embolised using gel foam. Post procedure, bleeding resolved immediately. A follow-up transvaginal ultrasound after a year revealed no evidence of the pseudoaneurysm and her fertility was preserved.
