Detection of HSV-1, HSV-2 and VZV Isolated from Cerebrospinal Fluid Samples of Children Suspected to Encephalitis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Encephalitis is an uncommon, serious brain infection that can cause fatality among children. The cause of most encephalitis remained unknown, yet viruses are the most well-known infectious agents that cause encephalitis. This study aimed to determine varicella-zoster virus (VZV) and herpes simplex virus type 1, 2 (HSV1/2) among individuals who are under 5 years of age in Iran. Materials and Methods: In this study, 149 cerebrospinal fluid samples of suspected patients of encephalitis were analyzed with some symptoms, such as seizure, fever, nausea loss of consciousness, and dizziness from Mofid Children's Hospital in Tehran, Iran. Then, the molecular evaluation of samples was performed using multiplex Polymerase Chain Reaction (PCR) for detecting HSV1/2 and VZV. Results: The mean age of the patients was 1.8 years. Also, 63.4% of children were male and 36.6% were female. Out of 149 tested samples, 11 (7.3%) showed the viral DNA for one of the herpes viruses (7.3%). Nine samples were HSV1 positive (6.0%) and two samples were VZV positive (1.3%). Fever and vomiting were the most frequent symptoms. The mean ± standard deviation (SD) WBC and counts in cerebrospinal fluid (CSF)-positive samples, and all included samples were 298.8 ± 552.7 cells/μL and 131.1 ± 474.6 cells/μL, respectively. Conclusions: Although viral encephalitis is considered a threat to children's health, with accurate diagnosis and appropriate antiviral drugs, death and neurological complications in children can be prevented.
