We report a case of acute onset of postoperative endophthalmitis following pars plana vitrectomy, in a healthy middle-aged male person, caused by Sphingomonas paucimobilis, a gram-negative bacillus widely distributed in the environment and reported to cause opportunistic infection in immunocompromised. The case showed complete resolution on vitrectomy and intravitreal antibiotics. The bacillus was multi-drug resistant, showing resistance to all known commonly used antibiotics except intermediate sensitivity to meropenem. There have been two reported cases of postoperative endophthalmitis caused by Sphingomonas paucimobilis following cataract surgery, but this is the first reported case following pars plana vitrectomy.

Cryptography or cryptology is look at of strategies for comfy verbal exchange in the presence of third parties called adversaries. Extra normally, cryptography is ready constructing and analysing protocols that prevent third events or the public from studying non-public messages. Many public key cryptography are available which are based totally on range idea however it has the downside of requirement of big computational strength, complexity and time intake for the duration of technology of key. To overcome these drawbacks, we analysed neural network is the quality way to generate mystery key. A neural network is a device which is designed to work like mind. It has the capability to perform complex calculations easily. The important thing fashioned by means of neural network is within the form of weights and neuronal functions that's difficult to break. Right here, textual content records might be use as an input statistics for cryptography in order that facts become unreadable for attackers and remains secure from them. Two neural networks are required for use here, one for encryption procedure and any other for decryption manner
