Assessment of PAP Device Usage and COVID-19 Related Anxiety in Patients with OSAS During COVID-19 Pandemics.

Objective: In this study, we aimed to determine the positive airway pressure (PAP) device usage and pandemic-related anxiety in obstructive sleep apnea syndrome (OSAS) patients during the pandemic.

Material And Methods: Five hundred twenty-seven OSAS patients were recruited into the study. A questionnaire consisting of 7 questions was filled to find out their Coronavirus disease-2019 (COVID-19)-related anxiety levels and PAP device usage.

Non-Hodgkin's Lymphoma of the Central Nervous System with N-Methyl-D-Aspartate Receptor Antibody Positivity - A Case Report.

Purpose: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, among the paraneoplastic syndromes, is a recently characterized autoimmune encephalitis most commonly associated with antibodies against subunits of the NMDAR in the central nervous system. As a paraneoplastic syndrome, anti-NMDAR encephalitis is commonly associated with ovarian teratomas, small cell lung carcinomas and testicular germ cell tumors. To our knowledge, there have been no cases with primary central nervous system lymphoma (PCNSL), a rare type of extranodal non-Hodgkin's lymphoma, without lymph node involvement associated with anti-NMDAR encephalitis.
