#multidrug-resistant organisms, #antibiotic resistance, #superbug, #MRSA, #CRE, #antibiotic misuse

Multidrug-resistant organisms are bacteria that have developed resistance to several types of antibiotics. They are also called 'superbugs.' Misuse and overuse of antibiotics are the main cause, and infection with them can be very hard to treat. Please take antibiotics only as prescribed by a doctor and for the prescribed length of time. If you have questions about antibiotic use, please consult your doctor.

Symptoms are often mild at first and easy to overlook, but without treatment, serious complications such as urinary tract infection and kidney failure can occur. If you have an underlying condition such as stroke or diabetes mellitus, please have your bladder function checked regularly.

#noise-induced hearing loss, #earphones, #tinnitus, #cochlea, #hearing damage, #noise, #hearing, #headphones, #double vision, #overlapping images, #ringing in the ear, #noise in the ear, #cannot hear, #difficulty hearing

Noise-induced hearing loss is a condition in which hearing is damaged by loud, sustained sound exposure.
