Aims and Scope

The Open Pediatric Medicine Journal is an Open Access online journal, which rapidly publishes research articles, reviews/mini-reviews, and letters in all areas of experimental and clinical research in pediatric medicine. The focus and the topics of this journal covers research areas relevant to pediatrics including preventive health care in pediatrics, pediatric surgery, pharmacology, genetic diseases, gene therapy, cardiology, endocrinology, gastroenterology, stomatology, psychology, preventive health care, delivery of care, biomedicine, ethics, innovations and other fields related to pediatric medicine.

The Open Pediatric Medicine Journal, a peer reviewed journal, is an important and reliable source of current information on developments in the field. The emphasis will be on publishing quality articles rapidly and making them freely available worldwide.

Herpes Simplex Virus (HSV) is the most common cause of acute sporadic focal encephalitis. Early Diagnosis is, therefore, crucial for predicting outcome. Improved laboratory technology and improved neuroimaging accessibility have enhanced our ability to diagnose this condition.


To assess the reliability of different investigative tools in diagnosing and subsequent management of herpes simplex encephalitis (HSE); as well as the impact of infection and its relapse on the outcome of a cohort of 18 children evaluated during a period of 13 years.


This combined prospective and retrospective study describes the clinical, laboratory, electroencephalographic and diagnostic imaging studies; and outcome in a cohort of 18 children with HSE over a period of 13 years. It also details the clinical and diagnostic features of 3 patients who relapsed.


The commonest initial presenting symptoms and signs were fever (100%), seizures (72%) irritability (50%) and weakness/hemiparesis (39%). Cerebrospinal fluid (CSF) pleocytosis was found in 62%, red blood cells (RBCs) >10x106/L in 81% and raised proteins (>0.59g/L) in 52%. Examination for herpes simplex virus (HSV) by polymerase chain reaction (PCR) was positive in 50% (6/12). Electroencephalographic changes were universally abnormal (17/17; 100%) and periodic lateralization discharges (PLEDS) were seen in 35% (6/17). During the acute stage (days 1-8 from symptom onset), magnetic resonance imaging (MRI) revealed abnormalities in 91% (10/11), cranial computed tomography (CT) in 50% (5/10) and single photon emission computed tomography (SPECT), within < 7 days, in 75% (6/8). All patients were treated with intravenous acyclovir. There were no deaths but 3 patients relapsed after periods ranging between 18 days and 66 months. Eleven (61%) patients had no or minor sequelae (good outcome) and 7 (39%) had moderate or severe sequelae (poor outcome). Delayed initiation of therapy (> 3days from onset of symptoms) had significant association with poor outcome (P = 0.002). Initial negative PCR results may become positive on subsequent CSF specimen.


Diagnosis of HSE requires combined clinical, laboratory, electroencephalographic and neuroimaging studies. Negative results of PCR do not exclude the infection and should not interrupt the treatment. Early diagnosis and initiation of treatment minimize the devastating effect of HSE. Full course treatment with acyclovir for 21 days is also crucial for prognosis and prevention of subsequent relapse.
