A Case of Hypercalcemic-Type Stage IVB Small-Cell Carcinoma of the Ovary in a Young Woman.

A 38-year-old nulliparous woman with severe obesity (BMI 66) and hypertension presented with constipation, fatigue, weakness, and poor appetite that had progressively worsened over the prior two to three weeks. Upon admission, the patient was found to have significant hypercalcemia, leukocytosis, and lactic acidosis. Computed tomography (CT) scan of the chest, abdomen, and pelvis revealed an adnexal mass with extensive lesions throughout her pelvis, abdomen, and chest.

A Case of Distal Common Bile Duct Obstruction Due to a Neuroendocrine Tumor.

Neuroendocrine tumors (NETs) are a rare subset of malignancies in the biliary tract that may have an aggressive and initially asymptomatic course. A 93-year-old female presented with four days of abdominal pain with associated nausea, jaundice, and brown-colored urine. A CT scan revealed a soft-tissue lesion measuring 1.

Prophylactic Spinal Cord Untethering in Children with Spinal Dysraphism Undergoing Thoracolumbar Fusion for Scoliosis.

Background: It remains unclear whether spinal cord untethering is necessary to reduce the chances of neurologic decline in children with myelomeningocele and complex closed spinal dysraphism who undergo thoracolumbar fusion for scoliosis. We sought to determine the neurologic and functional outcomes of children with spinal dysraphism undergoing spinal fusion for scoliosis with and without prophylactic spinal cord untethering.

Methods: Retrospective, single-center review of patients with spinal dysraphism treated with thoracolumbar fusion over the last 10 years (2009-2019) with or without prophylactic spinal cord untethering.

Acute Fever of Unknown Origin: A Presentation of West Nile Encephalitis.

Introduction: West Nile virus is an asymptomatic infection in most cases, but it can present with a rare complication of deadly neuroinvasive disease.

Case Presentation: A 81-year-old White man presented with altered mental status and fever of unknown origin. After extensive workup, he was diagnosed with West Nile encephalitis based on positive serology, lumbar puncture, and clinical presentation.

SARS-CoV-2-Associated Guillain-Barre Syndrome Obscured by Diabetes Mellitus Peripheral Neuropathy.

Multiple neurological complications, including Guillain-Barre syndrome (GBS), have been reported in association with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak. GBS has well-known associations with viruses such as influenza, human immunodeficiency virus, Zika, severe acute respiratory syndrome, Middle East respiratory syndrome, Epstein-Barr virus, and cytomegalovirus. Till date, there have been around 50 distinct published cases of GBS occurring concurrently or shortly after SARS-CoV-2 infection.

Peripheral Neuropathy as a Complication of SARS-Cov-2.

Previous reports have shown various neurological manifestations in about 36.4% of patients infected with SARS-Cov-2. However, peripheral neuropathy was only reported once before.

Amantadine Use for Postconcussion Syndrome.

The development of postconcussion syndrome after traumatic brain injury can result in a wide range of potentially debilitating symptoms that includes headaches, cognitive dysfunction, and mood disorders. Unfortunately, data on helpful medications are quite limited, particularly on the treatment of persistent headaches attributed to trauma. This retrospective medical record review used data collected from patients with a diagnosis of postconcussion syndrome in Mayo Clinic's Neurology and Physical Medicine and Rehabilitation outpatient clinics to evaluate the response of postconcussive symptoms to amantadine.

Early ophthalmologic features of Parkinson's disease: a review of preceding clinical and diagnostic markers.

Non-motor symptoms in Parkinson's disease are an important cause of morbidity and may even precede the onset of the motor features of the disease. Visual abnormalities are among the most frequent non-motor symptoms observed during the early stages of the disease. Some of the visual symptoms of Parkinson's disease can likely be explained by the presence of dopaminergic neurons within the retina, where the progressive loss of dopamine and the accumulation of α-synuclein within the retinal layers leads to visual dysfunction, while some are caused by abnormalities in cortical visual processing.
