A 'Decrescendo' in a Woman With Ascending Paralysis: A Diagnostic Challenge.

Guillain-Barre Syndrome (GBS) is an autoimmune condition that causes muscular weakness and can be potentially life-threatening if not identified early. GBS is diagnosed definitively by cerebrospinal fluid (CSF) analysis and electromyographic (EMG) studies. Identifying illnesses that may have triggered GBS is crucial, as they could affect the course of the disease. Our patient was a 27-year-old woman who developed lower extremity weakness a few days after being treated for a dental abscess. Laboratory and imaging studies ruled out central nervous system (CNS) lesions, myelopathies, and metabolic causes. Diagnosis was difficult due to inconclusive initial investigations, refusal of lumbar puncture, and delayed availability of EMG studies. Additionally, there were no identifiable triggers to support GBS as a diagnosis. During the hospital course, the patient developed tachycardia with new electrocardiogram (EKG) changes. A transthoracic echocardiogram (TTE) showed suspicious vegetation, and a transesophageal echocardiogram (TEE) confirmed severe mitral regurgitation. The new valvular lesions and autonomic dysfunction with worsening lower extremity weakness increased our suspicion of GBS. Intravenous immunoglobulin (IVIG) was administered empirically, but she developed bulbar symptoms, prompting admission to the intensive care unit (ICU). A lumbar puncture performed at this time was negative for albumino-cytological dissociation and CNS infections.  Signs of sepsis with valvular lesions raised concerns for infective endocarditis (IE). Due to recent treatment with antibiotics for dental abscess, a negative blood culture was a confounding factor in Duke's criteria, delaying the diagnosis of IE. Infectious disease experts suggested empirical treatment for suspected blood culture-negative infective endocarditis (BCNE) and valvular abscess. She was transferred to a cardiothoracic care facility for valvular surgery evaluation. EMG studies identified the patient's condition as the acute motor sensory axonal neuropathy (AMSAN) variant of GBS. The patient's antibodies tested positive for Campylobacter jejuni (C. Jejuni) immunoglobulin G (IgG). Since this indicates a past infection, it is uncertain whether C. Jejuni triggered the patient's GBS. However, new valvular vegetation and acute-onset lower extremity weakness make us hypothesize that BCNE may have triggered GBS.

Nutrition: Review on the Possible Treatment for Alzheimer's Disease.

Since its discovery some hundred years ago, Alzheimer's disease (AD), a neurodegenerative disease and an eminent cause of most dementia, continues to pose problems for affected families and society, especially in developed countries. With the approved medications by the Food and Drugs Administration in the United States, effectual treatment of AD apropos to the complete eradication of the disease continues to be elusive due to complexities relating to the pathophysiology of the disease. Nutrition has and continues to play a salient role in the survival of living organisms with no exception for human beings. Herein, we report the connection between nutrition and AD with particular attention to vitamins, curcumin, and the Mediterranean diet.
