Anomic aphasia after COVID-19 infection: a case report.

Purpose: This case reports on anomic aphasia related to COVID-19. Increasing knowledge about rare symptoms and complications may aid in the characterization of the disease, understand its pathophysiology, identify more quickly possible infected people and break the transmission chain. Case description: This work reports on the case of a middle-aged man who presented to his assistant psychiatrist complaining about difficulty with naming objects in his daily routine surroundings, with ten weeks of duration and following a SARS-CoV-2 infection. The organic study, including brain magnetic resonance imaging, was unremarkable. The symptoms resolved spontaneously within fourteen weeks. Comment: Neurological manifestations of COVID-19 may be related to the dysfunction of the blood-brain barrier, resulting in immune cell infiltration and neuroinflammation that can persist for weeks or months after the resolution of the infection. Weakened health after overcoming the infection acute phase is being reported increasingly and called post-COVID-syndrome. Rare disorders such anomic aphasia can occur in this syndrome.

Unveiling species diversity in collared frogs through morphological and bioacoustic evidence: a new Mannophryne (Amphibia, Aromobatidae) from Sierra de Aroa, northwestern Venezuela, and an amended definition and call description of M. herminae (Boettger, 1893).

Species diversity in collared frogs of the genus Mannophryne is presumed to be underestimated due to the paucity of external morphology characters, but combining morphology with bioacoustics and other lines of evidence has shown to be useful in delimiting species of this group. Herein we describe a new species of Mannophryne from Sierra de Aroa in northwestern Venezuela. The new species is morphologically similar to M. herminae but is readily recognized by its strikingly different advertisement call. It also can be distinguished from all its congeners by the unique combination of its small body size, general color pattern, basal toe webbing, and advertisement call consisting of long trills of single tonal notes emitted at a rate of 2-3 notes/s. Additionally, to facilitate future diagnosis of undescribed species related to M. herminae, we amend the definition of the latter, describe in detail its advertisement call, and redefine its known distribution range. The new species increases the number of described species of Mannophryne to 20.
