Reactivation of COVID-19 in a neurosurgical patient with early neuropsychiatric presentation. Does seroconversion mean immunity?

Surg Neurol Int 2021 19;12:166. Epub 2021 Apr 19.

Department of Neurosurgery, Fondazione IRCCS Policlinico San Matteo, Pavia, Italy.

Background: In the aftermath of COVID-19 outbreak, there is a strong need to find strategies to monitor SARSCoV-2 transmission. While the application of screening techniques plays a major role to this end, there is evidence challenging the real significance of seroconversion. We reported a case of COVID-19 reactivation associated with a neurosurgical operation with early neuropsychiatric involvement presumably promoted by olfactory and gustatory impairment in the first infection.

Abrupt Late-onset Psychosis as a Presentation of Coronavirus 2019 Disease (COVID-19): A Longitudinal Case Report.

J Psychiatr Pract 2021 Mar 5;27(2):131-136. Epub 2021 Mar 5.

Introduction: Coronavirus Disease 2019 (COVID-19) is a pandemic infection caused by the Severe Acute Respiratory Syndrome 2 Coronavirus (SARS-2-CoV). Although most prominently associated with pulmonary manifestations, COVID-19 is increasingly implicated in neuropsychiatric complications, including delirium and psychosis. There is a potential causal link between COVID-19 infection and psychotic symptoms; however, case reports to date have been incomplete, as the patients described had known psychiatric histories or other plausible medical causes for altered mental status.

A rare case report of Lilliputian and Brobdingnagian hallucinations in a case of pemphigus vulgaris.

Indian J Psychiatry 2020 Jul-Aug;62(4):435-436. Epub 2020 Jul 27.

Department of Psychiatry, AIIMS, Bhopal, Madhya Pradesh, India.

Pemphigus vulgaris is an autoimmune disorder characterized by intraepithelial, blistering lesions affecting the skin and mucous membrane. Psychiatric manifestations of pemphigus vulgaris are generally described secondary to steroid and immunosuppressant therapy though recent studies highlight independent association of pemphigus with psychotic disorders. We describe a unique development of Lilliputian hallucinations, their transformation into Brobdingnagian hallucinations on treatment with steroids and gradual resolution back to Lilliputian status on treatment with risperidone.

Actas Esp Psiquiatr 2020 May 1;48(3):126-37. Epub 2020 May 1.

Servicio de Psiquiatría, Hospital Universitari Vall d'Hebron. Barcelona. España Grupo de Psiquiatría, Salud Mental y Adicciones, Vall d'Hebron Research Institute (VHIR). Barcelona. España Biomedical Network Research Centre on Mental Health (CIBERSAM). Barcelona. España Departamento de Psiquiatría y Medicina Legal, Universitat Autònoma de Barcelona. Barcelona. España.

Quinolones are an antibiotic group widely used due to their antimicrobial action and security profile, however, it has been described neuropsychiatric adverse effects, being induced-psychotic episodes one of the most clinically relevant. Nevertheless, this secondary effect has been scarcely studied. A literature search using PRISMA guidelines was performed between 01/01/1962 and 01/31/2019 on PubMed and ScienceDirect, including manuscripts which described substance-induced psychotic disorder according to DSM-5 and in which the symptomatology was not attributable to an acute confusional state (delirium) or to other induced psychiatric disorders.

Acute Psychosis Consequent to Total Thyroidectomy: An Etiological Conundrum.

Cureus 2020 Jul 17;12(7):e9244. Epub 2020 Jul 17.

Endocrinology, All India Institute of Medical Sciences, Jodhpur, IND.

Total thyroidectomy has evolved from a vilipended surgery owing to its high mortality to one with commonly performed surgery with minimal complications. After a total thyroidectomy many patients are left hypothyroid and/or hypoparathyroid, and thus prone to develop neuropsychiatric complications. Although anxiety and depression are the common manifestations, acute psychosis consequent to total thyroidectomy is rarely reported. Read More
