ABSTRACT
Neuromyelitis optica spectrum disorder (NMOSD) is a disabling autoimmune astrocytopathic channelopathy, characterized by the presence of pathogenic antibodies to aquaporin-4 (AQP-4) water channels. Several viral infections including HIV, influenza virus, varicella zoster virus, and Epstein Barr virus, among others, have been alleged to trigger NMOSD in both immunocompetent and immunocompromised individuals. Neurological manifestations of coronavirus infectious disease of 2019 (COVID-19) have been ever evolving and the spectrum of neuraxial involvement is broadening. Albeit it may affect any area of the neural axis, the involvement of the spinal cord is rare compared to that of the brain and of the peripheral nervous system. Cases with acute longitudinally extensive transverse myelitis (LETM) have been recently reported in SARS-CoV-2 infection but did not fulfill the international consensus diagnostic criteria for NMOSD. AQP-4-antibody-seropositive NMOSD following SARS-CoV-2 infection had not yet been reported. We herein report a novel case of a previously healthy man who presented with a clinical picture of bouts of vomiting and hiccoughs (area postrema syndrome), which rapidly evolved to acute LETM, all following SARS-CoV-2 infection. He was finally diagnosed to be a case of seropositive NMOSD which presented as area postrema syndrome. The response to immunomodulatory drugs was excellent.
ABSTRACT
Landolfi's sign, alternating systolic constriction and diastolic dilatation of pupils, is a clinical hallmark of aortic regurgitation. It is thought to stem from exacerbation of physiological circulatory hippus in the vessels of iris due to a wide pulse pressure in a backdrop of severe aortic valvular incompetence. Degenerative and rheumatic heart diseases are exquisitely common in rural India and often these patients turn up late with complications to the primary care physicians. Herein, the authors report a 34-year-old pregnant female who presented with acute heart failure, and on examination, Landolfi's sign was found. It was immediately followed by Doppler echocardiography to stamp it as a case of severe aortic regurgitation. The patient was stabilized with anti-failure medications and feto-maternal health was closely monitored. The authors want to conclude claiming that bedside clinical training in cardiology will forever remain important, more so, while dealing patients at non-sophisticated primary health-care facilities. Besides, they also argue that basic tool supports like an echocardiography should be made available at those centers.
