Neuromyelitis optica spectrum disorder is an autoimmune demyelinating disease with high relative prevalence in the East Asian population. Clinical manifestations include optic neuritis, longitudinally extensive transverse myelitis, area postrema syndrome, brainstem syndromes, and diencephalic syndromes.In this case report, we present a case of neuromyelitis optica spectrum disorder that developed 10 days after the first dose of the severe acute respiratory syndrome coronavirus 2 mRNA-1273 vaccine. The patient was a previously healthy White female, completely independent and functional at baseline. She presented with bilateral lower-extremity numbness/tingling, weakness, and urinary retention. Although her neuromyelitis optica IgG was negative, the MRI was consistent with neuromyelitis optica involving and spanning longitudinally the C6-T2 vertebrae. She was treated with IV steroids and her symptoms improved.Given the novelty of the COVID-19 vaccines and the paucity of literature regarding their adverse effects, case reports such as ours provide unique information that aids healthcare providers in accurately diagnosing and treating patients, ultimately minimizing long-term neurologic deficits.
Obstructive sleep apnea (OSA) is a disease process involving recurrent pharyngeal collapse during sleep, resulting in apneic episodes. Clinically, symptoms can include snoring, sudden awakening with a chokinglike sensation, excessive somnolence, non-restorative sleep, difficulty in starting or maintaining sleep, and fatigue. It results in impaired gas exchange, subsequently causing various cardiovascular, metabolic, and neurocognitive pathologies. Historically, OSA has been underdiagnosed and undertreated, especially in women.OSA is associated with WHO (World Health Organization) class III pulmonary hypertension (PH) or PH due to lung disease. PH is a concerning complication of OSA and thought to occur in roughly 20% of individuals with OSA. The pathogenesis of PH in OSA can include pulmonary artery vasoconstriction and remodeling. Patients suffering from OSA who develop PH tend to have worse cardiovascular and pulmonary changes. We present a thorough review of the literature examining the interplay between OSA and PH.
Limited scleroderma falls under the umbrella of systemic sclerosis, an autoimmune disease that presents with multiorgan dysfunction that includes pulmonary arterial hypertension. We examine a case of pulmonary arterial hypertension in an elderly nonsmoker with a history of limited scleroderma. The patient presented with abdominal tenderness and was diagnosed with a sigmoid colonic stricture. She underwent laparoscopic bowel resection. During and after her surgery, she suffered from worsening respiratory function and decompensated, developing a large pleural effusion that led to a thoracentesis and a prolonged hospital course. Patients with scleroderma can develop acute symptoms involving several organ systems, including the colonic tract and lungs, as seen in our patient. A thorough workup and continuous close management and monitoring are necessary to avoid further complications in these patients, especially in the postoperative period.
Pseudohypoparathyroidism is a rare disorder that is characterized by hypocalcemia and hyperphosphatemia that are unresponsive to the parathyroid hormone. We present a unique case of pseudohypoparathyroidism seen in a 33-year-old male who presented with abnormal laboratory findings including hypocalcemia, hypokalemia, hypomagnesemia, hyperphosphatemia, and positive Trousseau's sign.Pseudohypoparathyroidism is a rare phenomenon, with an estimated prevalence between 0.3 and 1.1 cases per 100,000. Genetic mutations have been noted to play a role in the presentation of pseudohypoparathyroidism. Clinical phenotypical manifestations can include brachydactyly, short stature, a stocky build, and a round face. Similar routine follow-up and treatment as traditional hypoparathyroidism is practiced. This case highlights a unique endocrinologic pathology that clinicians should be more aware of, as it can be confused with hypoparathyroidism.
Wernicke encephalopathy has traditionally been associated with chronic alcohol abuse leading to thiamine deficiency. Clinical symptoms include mentation change, gait ataxia, and oculomotor abnormalities. However, it is often an underdiagnosed condition in patients suffering from chronic malnutrition, especially in the West. We examine a unique case of non-alcoholic Wernicke encephalopathy in an elderly patient.The patient had a long history of chronic malnutrition due to her atypical diet, consuming an unbalanced diet deprived of thiamine, unbeknownst to her. She presented with symptoms of encephalopathy, recurrent falls, and pupillary changes. After exhausting all other therapeutic interventions, she received a thiamine infusion; her mentation and other symptoms improved dramatically.Thiamine deficiency can lead to severe complications, including Wernicke encephalopathy and cardiomyopathy. Wernicke encephalopathy can progress to Korsakoff syndrome, which is characterized by amnesia and confabulation. Case reports, such as ours, may remind clinicians to keep thiamine deficiency as a viable differential while evaluating acute encephalopathy, especially in the malnourished geriatric population.
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.
