Consultation-Liaison Psychiatry-From Theory to Clinical Practice: an Observational Study in a Psychiatric Unit in the General Hospital of Perugia.

BACKGROUND: Subjects suffering from psychiatric disorders are frequently hospitalized due to medical comorbidities. In the present study, we analyzed consultation-liaison psychiatry (CLP) activity in a General Hospital, describing the sociodemographic, diagnostic, and therapeutic characteristics of the evaluated subjects, as well as reasons for consultation requests. SUBJECTS AND METHODS: Data concerning psychiatric consultation performed at the Perugia General Hospital during a 1-year period (01/06/2022-20/06/2023) were collected and analyzed by means of descriptive statistics. RESULTS: A total of 707 psychiatric consultations were performed. The primary reason that led to psychiatric consultations was psychomotor agitation. 85 (18.5%) patients attempted suicide; the most frequent modality was the assumption of drugs at non-therapeutic doses. The 72% of the sample (n=509) presented a clear-cut medical comorbidity. In most cases, subjects were referred to Community Mental Health and Addiction services (n=22, 32.4%). CONCLUSIONS: CLP plays a crucial role in the perspective of the overall well-being of hospitalized subjects, but also for the overall management of complex cases. Despite this, a homogeneous approach with standardized guidelines is needed in this field.

Neurotropism and Neuropsychiatric Symptomsi in Patients with COVID-19.

BACKGROUND: The Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-CoV-2). Beyond the most common clinical features of COVID-19, mainly represented by respiratory symptoms, other systems may be interested by the infection. Among these, through a neurotropic pathway, the central nervous system (CNS) may be affected by the virus, leading to developing neuropsychiatric symptoms. Particularly, this study focuses on neurological symptoms determined by the Sars-CoV-2 infection, as well as on the underlying pathogenetic processes. METHODS: For the present review, we followed a narrative approach. A literature search was carried out concerning the neurological consequences of COVID-19. Papers were screened, focusing on the clinical manifestations interesting the CNS and on their possible role in the early diagnosis of the disease. RESULTS: We display the most significant neurological clinical manifestations of COVID-19. Common neurological manifestations (ageusia, anosmia, and encephalitis) are first described. Subsequently, we provide a focus on delirium and its possible pathogenetic and clinical correlates. Delirium is not only a possible resultant of the COVID-19 neurotropism, but it may also be precipitated by a number of environmental factors that assume further relevance during the pandemic. CONCLUSIONS: Neuropsychiatric symptoms, and particularly delirium, can help identifying the infection at an early stage. Tailored treatments should be identified in order to prevent complications.
