    The state of the vestibular system was evaluated in 30 postpartum women following gestosis and 25 controls after uncomplicated pregnancy. Examination using the electronystagmographic technique failed to reveal spontaneous nystagmus (Ny) in the latter group whereas 13.3% and 30% women of the former group had it with the eyes open and closed respectively. Provocative functional tests significantly improved detectability of Ny. Hyperventilation was associated with Ny in 80% and 12% of the women after complicated and uneventful pregnancy respectively while orthostatic test revealed Ny in 63% and 12% of them. Active head rotation with closed eyes produced well-apparent experimental Ny in women of both groups, but it was significantly more pronounced in the former one. Post-gestosis women displayed markedly impaired reaction in vestibular-ocular reflex suppression test. It is concluded that 80% of the women with complicated pregnancy exhibited vestibular dysfunction of central origin in the postpartum period.

    The Vestibular System01:29

    The Vestibular System

    The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

    Equilibrium and Balance

    The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

    Mitral Valve Prolapse III: Nursing Management

    The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

    Mitral Valve Prolapse II: Assessment and Management

    IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.

    Pathophysiology of Diabetes

    Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
    Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

    Mitral Valve Prolapse I: Introduction

    IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
