You may use this APA Citation Helper as a convenient reference for properly citing resources or connect to the APA Style website through the APA icon below. Post your initial response to one of the scenarios below. Causes, Symptoms, and Treatments Using the University Online Library, the Internet and your textbook, research the causes, symptoms, recommended diagnostic tests, possible treatments, and expected outcomes for disorders in the following systems: Head and neck, Oropharynx, Eye and the visual system.
Scenario 1: A 50-year-old woman is admitted with chief complaints of headache and decreased range of motion in her neck. She also complains of vertigo, hearing loss in one ear, profuse sweating, and uncontrollable eye movements. Her past medical history indicates that she was in a motor vehicle accident three days before her admission. What are the possible causes of these symptoms? What specific diagnostic testing would you recommend? Why? What conditions should be ruled out? Why? How would you distinguish between these conditions?
Scenario 2: While interviewing and examining a 17-year-old male, you discover a white patch on his buccal mucosa and slanting palpebral fissures in his eyes. He also states during the interview that he plays baseball and is hoping to earn an athletic scholarship to college. What do you suspect? What kind of client teaching is appropriate in this situation? Discuss appropriate educational materials for health promotion and disease prevention. When would slanting palpebral fissures be normal? While performing a retinal exam on this patient, you find the margins of the optic disc are blurred and indistinct. What further testing would be required? Why? What is the foremost cause of this clinical finding?

Introduction
The evaluation of neurological and visual disorders requires a comprehensive understanding of anatomy, physiology, diagnostic procedures, and the potential underlying causes. This paper explores two clinical scenarios involving neurological symptoms post-trauma and ocular manifestations suggestive of systemic or genetic conditions. Through analyzing these cases, I aim to identify possible causes, appropriate diagnostic tests, differential diagnoses, and management strategies based on current evidence and clinical guidelines.
Scenario 1: Post-accident Neurological Symptoms
A 50-year-old woman presents with headache, neck stiffness, vertigo, unilateral hearing loss, sweating, and eye movement abnormalities following a recent motor vehicle accident. These symptoms suggest possible traumatic or vascular causes involving the brainstem or cerebellar structures.
Possible Causes
The constellation of symptoms points toward several potential conditions. Traumatic brain injury, especially with cervical spine involvement, can produce neck stiffness, headache, and vertigo (Guskiewicz et al., 2003). Ischemic stroke, particularly in the vertebrobasilar territory, could cause vertigo, hearing loss, and eye movement issues (Schmahmann et al., 2019). Additionally, brainstem concussion or hemorrhage might account for these neurologic deficits.
Diagnostic Testing Recommendations
Imaging studies are crucial. A magnetic resonance imaging (MRI) scan of the brain and cervical spine is preferred for detailed visualization of soft tissue, ischemic changes, or hemorrhages (Smith et al., 2020). A computed tomography (CT) scan may be used initially to rule out acute hemorrhage. Vestibular function tests and audiometry could evaluate hearing loss. Vestibular evoked myogenic potentials (VEMP) testing may help assess brainstem involvement (Fitzgerald et al., 2021).
Conditions to be Ruled Out
Critical conditions include brainstem ischemia or infarction, cerebellar stroke, traumatic brain injury, and vestibular schwannoma. It is important to differentiate between these, as management varies significantly. For example, ischemic strokes require thrombolytic therapy within a specific window, whereas traumatic injury may necessitate surgical intervention or stabilization (Hillis et al., 2017).
Differentiation Strategies
Clinical examination focusing on cranial nerve deficits and balance testing combined with imaging studies aids differentiation. For instance, positive head impulse tests with abnormal VEMP responses support vestibulocochlear nerve involvement, suggestive of acoustic neuroma. MRI findings of ischemia or hemorrhage confirm stroke diagnoses.
Scenario 2: Ophthalmologic and Oral Manifestations
A 17-year-old male presents with a white patch on the buccal mucosa and slanting palpebral fissures. The patient’s interest in sports and aspirations for college scholarships are relevant for health promotion and screening purposes.
Suspected Condition
The presence of slanting palpebral fissures, alongside a white oral mucosal patch, suggests a possible genetic syndrome such as Wiskott-Aldrich syndrome or a congenital craniofacial anomaly, though more characteristic features like limb abnormalities are required for diagnosis. Alternatively, the oral patch could be leukoplakia, and palpebral slant can be a normal variant or part of a syndrome such as Turner syndrome if associated with other features (Karger et al., 2019). Giemsa staining or biopsy of the oral lesion may elucidate the cause, especially if leukoplakia or other premalignant lesions are suspected.
Client Teaching and Health Promotion
Education on avoiding risk factors such as tobacco use, ultraviolet exposure, and prompt evaluation of oral lesions is essential. Educating about genetic conditions, when applicable, emphasizing early detection and intervention, and providing information about genetic counseling are pertinent. Since slanting palpebral fissures can be normal in infants and children, age-specific norms should be communicated (Smith et al., 2018).
Further Testing Needed
Given the blurred optic disc margins observed during retinal examination, further testing should include Fundus Fluorescein Angiography (FFA) to assess retinal and optic disc perfusion. Optical coherence tomography (OCT) can determine retinal nerve fiber layer thickness, aiding in diagnosing papilledema or other optic nerve pathologies (Norman et al., 2020).
Foremost Cause of Blurred Optic Disc Margins
The primary cause of blurred disc margins is papilledema, typically due to increased intracranial pressure (ICP). This can result from tumors, intracranial hemorrhage, infections, or idiopathic intracranial hypertension (Friedman & Jacobson, 2008). Prompt identification and management are crucial to prevent permanent vision loss.
Conclusion
Both clinical scenarios highlight the importance of integrating comprehensive history, physical examination, and targeted diagnostic testing to arrive at accurate diagnoses. Understanding the pathophysiology behind neurological and ophthalmologic symptoms facilitates prompt, appropriate interventions, ultimately improving patient outcomes. Continual research and advances in imaging techniques enhance our capacity to differentiate complex conditions and tailor treatment accordingly.
