Mild sensory symptoms during SARS-CoV-2 infection among healthcare professionals.

INTRODUCTION: It is not yet possible to estimate the proportion of patients with COVID-19 who present distinguishable classical neurological symptoms and syndromes. The objective of this study is to estimate the incidence of sensory symptoms (hypoaesthesia, paraesthesia, and hyperalgesia) in physicians who have presented the disease at Hospital Universitario Fundación Alcorcón (HUFA) in Madrid; to establish the relationship between sensory symptoms and the presence of other signs of infection; and to study their association with the severity of COVID-19. METHODS: We conducted a descriptive, cross-sectional, retrospective, observational study. HUFA physicians who presented SARS-CoV-2 infection between 1 March and 25 July 2020 were included in the study. A voluntary, anonymous survey was distributed via corporate email. Sociodemographic and clinical characteristics were collected from professionals with PCR- or serology-confirmed COVID-19. RESULTS: The survey was sent to 801 physicians and we received 89 responses. The mean age of respondents was 38.28 years. A total of 17.98% presented sensory symptoms. A significant relationship was found between the presence of paraesthesia and cough, fever, myalgia, asthaenia, and dyspnoea. A significant relationship was also found between paraesthesia and the need for treatment and admission due to COVID-19. Sensory symptoms were present from the fifth day of illness in 87.4% of cases. CONCLUSIONS: SARS-CoV-2 infection can be associated with sensory symptoms, mostly in severe cases. Sensory symptoms often appear after a time interval, and may be caused by a parainfectious syndrome with an autoimmunity background.

[Gliomatosis cerebri: review of 22 patients]. / Gliomatosis cerebral: estudio de 22 pacientes.

INTRODUCTION: gliomatosis cerebri is a diffuse astrocytic neoplasm that involves more than two lobes of the brain. Treatment is not well defined and the prognosis is considered poor. METHODS: retrospective analysis of 22 patients with gliomatosis cerebri. RESULTS: we identified 17 men and 5 women (median age 54 years) seen in a Division of Neuro-oncology over a 6 year period. Patients presented with focal sensorimotor or visual deficits (86.4%), seizures (36.4%), cognitive dysfunction (27.3%), or headache (27.3%), suggesting in some cases stroke, migraine, or limbic encephalitis. All patients had bilateral involvement; the regions involved included, temporal (19), basal ganglia (18), frontal (17), parietal (17), corpus callosum (10), and occipital (9). The most frequent pathological findings were grade III astrocytoma (36.4%), grade II astrocytoma (22.7%), and grade IV astrocytoma (18.3%). Nine patients were diagnosed within the first month of symptom development, 11 between the first month and 1 year, and 2 after one year. Seventeen patients received treatment with chemotherapy, radiotherapy or both, and 12 patients (70.6%) had a clinical or radiological response. The median follow-up was 13 months, median progression free survival 6 months, and median survival 9,5 months (15 months if the patients received treatment). Eight patients had thromboembolic events. CONCLUSIONS: gliomatosis cerebri has a variable clinical course. Treatment often results in clinical responses. In this study de median survival of patients who received treatment was similar to that reported in series of glioblastoma multiforme.

[Third cranial nerve palsy due to intracranial hypotension syndrome]. / Neuropatía del tercer par craneal secundaria al síndrome de hipotensión intracraneal.

INTRODUCTION: Intracranial hypotension syndrome (IHS) is clinically defined by orthostatic headache due to cerebrospinal fluid (CSF) hypovolemia. It is frequently associated with lower cranial nerve (CN) paresis, especially the 6th one. However, neuropathy of the 3rd CN is rare. CASE REPORT: A 43 year old man presented with orthostatic headache and vertical diplopia of gradual onset. Clinical examination detected incomplete, pupil sparing left third CN palsy. Magnetic resonance imaging (MRI) of the brain and spine demonstrated typical abnormalities that confirmed the clinical suspicion of IHS. Lumbar puncture showed an opening pressure of 5 cm of water. CSF disclosed mild protein elevation (0.63 g/l) and lymphocytic pleocytosis (13 cells/ml). A history of spinal trauma three months prior to the onset of the symptoms and lumbar fractures identified in a spine computed tomography scan suggested the likely origin of the CSF leak. The symptoms responded to conservative measures in three months and a cranial MRI performed ten months later was normal. DISCUSSION: Third CN palsy is an extremely unusual manifestation of IHS and contributes to the expansion of its clinical spectrum.
