Multiple-organ failure as a result of non-COVID-19 coronavirus infection.

Coronavirus infections (CoV) are common in pediatric patients. In general, they produce a mild clinical presentation consisting of an upper respiratory tract infection that does not usually infect the lungs, with the exception of preterm infants and children with chronic diseases. These infections exceptionally affect other organs (heart, brain, gastrointestinal tract), thus increasing their severity.

Reading and writing direction effects on the aesthetic appreciation of photographs.

Does reading and writing direction (RWD) influence the aesthetic appreciation of photography? Pérez González showed that nineteenth-century Iranian and Spanish professional photographers manifest lateral biases linked to RWD in their compositions. The present study aimed to test whether a population sample showed similar biases. Photographs with left-to-right (L-R) and right-to-left (R-L) directionality were selected from Pérez González's collections and presented in both original and mirror-reversed forms to Spanish (L-R readers) and Moroccan (R-L readers) participants.

Lateral organisation in nineteenth-century studio photographs is influenced by the direction of writing: a comparison of Iranian and Spanish photographs.

The direction of reading has been found to have a significant effect upon aesthetic preference, with left-to-right readers showing a preference for stimuli with a rightward directionality while right-to-left readers prefer stimuli with a leftward directionality. This study looks at a large set of posed, studio photographs to study the cultural interaction between direction of reading and lateral organisation, comparing a corpus of 735 nineteenth-century photographs from Iran (right-to-left reading) with a similar corpus of 898 photographs from Spain (left-to-right readers). Five separate types of composition were studied: linear ordering, usually by height; couples; individuals posing by a chair; individuals posing by a table; and portraits.

[Aseptic meningitis in an adult population. Etiology and utility of molecular techniques in the clinical management of patients].

Objective: This study describes the epidemiological, clinical and microbiological features of acute aseptic meningitis (AAM) in an adult population, and evaluates the impact of microbiological results on the clinical management of patients.

Patients And Methods: Cases of AAM were prospectively collected between 2007 and 2010 among immunocompetent patients over 14 years-old. Enteroviruses and herpes viruses were determined using nucleic acids detection in CSF.

Development and implementation of influenza a virus subtyping and detection of genotypic resistance to neuraminidase inhibitors.

Influenza virus hemagglutinin and neuraminidase, surface glycoproteins with an essential role in viral pathogenesis, are important antigen determinants and essential markers for epidemiological surveillance. Neuraminidase is also a suitable target for designing antiviral drugs. The introduction into clinical practice of neuraminidase inhibitors and the development of random point mutations have increased the emergence of drug-resistant viruses.

[Value of the polymerase chain reaction in the diagnosis of herpes infections of the nervous system].

Objective: To assess the performance of a polymerase chain reaction (PCR) method in cerebrospinal fluid (CSF) for the diagnosis of nervous system infections caused by herpesvirus, and to estimate the incidence of encephalitis due to herpes simplex virus type 1 in the adult population of the island of Gran Canaria.

Methods: We studied 330 CSF specimens from 312 patients (281 HIV-negative and 31 HIV-positive) remitted to investigate clinically suspected encephalitis or meningitis, or to study neuropathy or demyelinating disease. A multiplex PCR technique was used to detect herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), human cytomegalovirus (CMV), Epstein-Barr virus and human herpesvirus type 6.
