Meningoencefalitis por virus Varicella-Zóster posterior a infección por SARS-CoV2: Reporte de dos casos / Meningoencephalitis caused by Varicella-Zoster virus after SARS-CoV2 infection: Two cases report

RESUMEN La meningoencefalitis por el VZV es una patología poco frecuente que se presenta con la reactivación del virus dentro del organismo. OBJETIVO: Describir la presentación clínica de dos pacientes con neuroinfección por VZV posteriormente a infección por SARS-CoV-2. REPORTE DEL CASO: El primer caso corresponde a un hombre de 59 años con antecedente de neumonía moderada por SARS-CoV-2 que después cursó con meningoencefalitis por VZV y, además, desarrolló un síndrome de Ramsay Hunt. El segundo caso es el de una mujer de 37 años con antecedente de infección leve por SARS CoV-2 con un cuadro de cefalea con signos de alarma, en quien se documentó neuroinfección por VZV

ABSTRACT Meningoencephalitis caused by varicella zoster virus is a rare pathology that presents due to the reactivation of the virus in the organism OBJECTIVE: To describe the clinical presentation of two patients with VZV neuroinfection presented after a SARS CoV-2 infection. CASE REPORT: The first case is a 59 year old male with previous moderate SARS CoV-2 infection who presented meningoencephalitis and was diagnosed with Ramsay Hunt's Syndrome. The second case is a 37 year old female with previous SARS CoV-2 infection who presented with an acute onset headache and was documented with VZV neuroinfection.

Impact of psychiatric symptoms and sleep disorders on the quality of life of patients with Parkinson's disease.

The objective of this study is to assess how the non-motor symptoms of Parkinson's disease (PD), such as depression, cognitive deterioration, neuropsychiatric and sleep disorders, affect the quality of life, and to compare them with the motor symptoms in order to determine their real impact. A cross-sectional study was designed including 99 patients (mean age 68.5 ± 9.9 years, duration of disease 8.7 ± 6.2 years). Demographic data, onset of PD, years on treatment with levodopa (LD), class of dopaminergic drug prescribed, and dosages were obtained. The following scales were used: quality of life (PDQ-39), Unified Parkinson's Disease Rating Scale (UPDRS I-IV), Parkinson Disease Sleep Scale (PDSS) and daytime sleepiness (Epworth), Mini-Mental State Examination, depression (HAM-D), and the neuropsychiatric inventory (NPI-10). The PDQ-39 summary index (PDQ-39 SI) was 24.7 ± 13.2. A linear regression model including all variables showed that four independent variables accounted for 67.2% of the variance in the PDQ-39 SI (F = 33,277; p < 0.001): NPI, PDSS, UPDRS IV, and UPDRS I. When sub-items of the NPI, PDSS and UPDRS IV scales are analyzed, significant correlations (p < 0.001) are found between the PDQ-39 SI and depression, agitation, apathy, anxiety, hallucinations, delusions, incontinence of urine, morning painful posturing, restlessness in bed, morning fatigue, duration of off periods, unpredictable and predictable off periods, early morning dystonia, and sudden off periods. Neuropsychiatric symptoms, especially depression, nighttime sleep disorders such as urinary incontinence, nighttime restlessness, morning fatigue and somnolence, off-period dystonia and motor fluctuations are the variables that most affect the quality of life of patients with PD.

Central venous catheter-related infection: a prospective, observational study to assess the incidence rate at a teaching hospital in Argentina.

One hundred fifty-one central venous catheters (CVCs) were observed for development of infection. The infection rate was higher for CVCs with a duration of less than 6 days than for those with a longer duration. Our data suggest that scheduled replacement of CVCs is not necessary.
