Herpes Simplex Virus Type 1 Encephalitis in a Six-Year-Old Girl: A Case Report From Latin America.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Herpes simplex virus type 1 (HSV-1) encephalitis is a severe neurological condition that can cause significant morbidity and mortality, particularly in pediatric patients. Prompt recognition and treatment are crucial to preventing long-term complications. This case report aims to highlight the diagnostic challenges and importance of early antiviral therapy in pediatric HSV-1 encephalitis. We describe a six-year-old girl admitted with fever, headache, vomiting, progressive somnolence, and a prolonged generalized tonic-clonic seizure. Upon admission, she exhibited oral aphthae, somnolence, and mild hyperkalemia. Brain magnetic resonance imaging revealed unilateral hyperintensity in the right mesial temporal lobe involving the hippocampus and parahippocampal gyrus. Electroencephalography demonstrated diffuse cortical dysfunction without epileptiform discharges. Cerebrospinal fluid polymerase chain reaction confirmed HSV-1 infection, while other inflammatory parameters remained within normal limits. Empirical intravenous acyclovir was initiated immediately and continued for 21 days, with favorable tolerance and neurological improvement. At the time of last follow-up, the patient remained clinically stable, with plans for long-term neurological monitoring. This case underscores the importance of early diagnosis and comprehensive management, including neuroimaging, electroencephalography, and cerebrospinal fluid analysis, to guide timely therapeutic decisions and prevent irreversible neurological damage in pediatric patients.
