Mononeuropathy of the lower limb, against the background of vaccination against polio, in an early age child is a clinical case

Background. Mononeuropathy of the lower extremities (myelopathy) is a sporadic disease in young children characterized by the development of acute flaccid paralysis syndrome: motor deficiency, changes in muscle tone, tendon reflexes, and electroneuromyography parameters. The provoking factor for the development of the disease may be: vaccinations, injuries, previous infections. The etiological factor of the disease is more often enteroviruses, less often herpesviruses, influenza viruses, etc. The main symptoms of the disease are represented by paresis of individual muscle groups, more often quadriceps, calf, resulting in gait disorders: lameness, knee flexion, foot droop. Monopares is of the peroneal and tibial nerves is predominant. The course of the disease is favorable. Recovery of movements in the affected limb occurs within 4-6 weeks or more. The presence of acute flaccid paralysis syndrome in a patient requires the exclusion of a number of diseases: Guillain – Barre syndrome, encephalitis, myelitis, traumatic and toxic neuropathies, neoplasms of peripheral nerves and spinal cord, etc., and, taking into account the epidemiological situation of the present time, polio.

Results. The article presents literature data and own clinical observation of acute infectious mononeuropathy of the lower extremity, which developed in an early age child against the background of vaccination with live polio oral vaccine of the 1st and 3rd types. The description of the symptoms and course of the disease is presented in the form of an analysis of the clinical situation, for the purpose of medical education and differential diagnosis with polio.
