Isolated oculomotor disorders caused by central nervous system damage are quite rare. As a rule, they are combined with other signs of cerebral trunk damage. A clinical case with the focus of amyelination in the cerebral trunk area, which manifests itself in the form of bilateral horizontal gaze palsy in the absence of other focal neurological symptoms is presented. A complete regression of oculomotor disorders was observed against the background of glucocorticosteroid therapy. A differential research was carried out among amyelinating, ophthalmic, endocrinologic diseases, ANCA-associated vasculitis (AAV).
The article presents a case of acute uremic neuropathy. Without any visible cause, a 71-year-old patient felt weakness in legs and numbness in feet. Her neurological status assessment on admission to the hospital showed peripheral tetraparesis and impaired sensitivity of the polyneuropathic type. Neurological symptoms appeared due to renal dysfunction, which had been confi rmed with laboratory test. Electroneuromyography revealed signs of acute demyelinating polyneuropathy. Аt the hospital, the patient was diagnosed Alzheimer’s disease. The treatment provided at the hospital led to normalization of her laboratory parameters and complete restoration of motor functions. The peculiarity of the presented clinical case is that the patient started violating drinking regime due to her cognitive impairment which resulted in renal dysfunction and acute uremic neuropathy. The other peculiarity of the case is that it was enough to correct the water-electrolyte disorders to fully restore the patient’s motor functions within a month, without the use of dialysis. Finally, the article discusses the issue of pathogenesis and diff erential diagnosis of other types of polyneuropathies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
