Hiccup: The Striking Manifestation of Hyponatremia Due to Ischemic Stroke-Induced Cerebral Salt Wasting Syndrome (CSWS).

Among many clinical symptoms, hiccups are an infrequent presentation of hyponatremia. Hyponatremia indicates a serum sodium level of less than 135 mmol/l, the most common reported electrolyte abnormality. Cerebral salt wasting syndrome is a less common cause of hyponatremia, which can arise from a spectrum of brain pathology. This case report brings attention to a case of hyponatremia due to cerebral salt wasting syndrome in a 76-year-old man who suffered from an ischemic stroke. The hyponatremia appeared vaguely, with only a hiccup as a symptom.

Exacerbation of Pre-existing Neurological Symptoms With COVID-19 in Patients With Chronic Neurological Diseases: An Updated Systematic Review.

The neurotropism of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can potentially explain the worsening of symptoms in patients with a history of neurological conditions such as stroke, Parkinson's disease, Alzheimer's, and epilepsy. Several studies have reported that these pre-existing conditions may worsen with a higher frequency of flare-ups, thus resulting in a more significant risk of patient mortality. In this review, we sought to provide an overview of the relationship between pre-existing neurological disorders and COVID-19, focusing on whether the initial infection directly influenced the severity of symptoms. We systematically searched the electronic database PubMed (MEDLINE) and used specific keywords related to our aims from January 2020 to July 2022. All articles published on COVID-19 with keywords pertaining to pre-existing neurological diseases were retrieved and subsequently analyzed. After independent review, the data from 107 articles were selected and evaluated. After analyzing the data from selected articles reviewing the effect of COVID-19 on neurological conditions, we have documented the relationship between said pre-existing neurological diseases, showing an increased risk of hospitalization, admission length, worsening of symptoms, and even mortality in COVID-19 patients.

Gorham-Stout disease, a diagnosis of exclusion.

Gorham-Stout disease (GSD) also known as vanishing bone disease is an idiopathic and rare condition characterized by gross and progressive bone loss along with excessive growth of vascular and lymphatic tissue. Very little is known about the pathogenesis of GSD, which makes the diagnosis challenging and often diagnosed by elimination. We report a case of GSD in a 41-year-old male patient. He presented with bone pain and initial imaging showed widespread osteolytic lesions in the cervical and mid thoracic spine, ribs, sternum, clavicles, scapula, and humerus. Two percutaneous bone biopsies were performed, followed by an open spine biopsy of the lumber 2 spinous process for histological examination. Unfortunately, no diagnosis was reached. Although, he was treated symptomatically, he kept enduring pain and presented again after 7 months. His laboratory values were out of the normal range which prompted thorough investigations. New imaging and bone biopsy revealed multiple osteolytic lesions and vascular lesion with cavernous morphology respectively. GSD was diagnosed after ruling out a neoplastic process and confirming the cavernous morphology with immunohistochemical stain. He was treated symptomatically with immunomodulators, bisphosphonates, and supplements. Patient was counseled to see the specialist regularly. This case will help to increase familiarity and shed insights in the diagnosis of GSD.
