The Many Faces of Neurological Neonatal Herpes Simplex Virus Infection.

This case series explores the various manifestations of central nervous system (CNS) involvement in neonatal herpes simplex virus (HSV) infection and highlights the challenges involved in their diagnosis and treatment. Neonatal HSV infection is a rare but serious condition that can have significant neurological consequences. The article presents three cases of neonatal HSV infection, all involving the CNS, each characterized by distinct clinical features and outcomes. Case 1 describes a three-week-old male with severe HSV meningoencephalitis resulting in poor response to treatment and death. Cases 2 and 3 describe younger neonates who presented early in the disease course with disseminated infection and skin, eye, and mouth (SEM) lesions. Although both patients had CNS involvement, their outcomes were remarkably favorable. The wide range of clinical presentations of CNS manifestations in neonatal HSV infection, ranging from nonspecific to evident neurological symptoms, underscores the need for a high index of suspicion and comprehensive evaluation to ensure early diagnosis and appropriate treatment. However, it also notes that even with timely treatment, some cases may still have a poor prognosis.

Report of Haemophilus Influenzae serotype a intracranial infections in older children.

Introduction: Haemophilus influenzae (Hi) is subdivided into typeable (a-f) and non-typeable groups. Hi serotype b (Hib) has historically been one of the important pathogens responsible for invasive infection. However, after widespread Hib vaccination, the emergence of other Hi serotypes, specifically Hi serotype a (Hia), was noted during the last few decades, mostly in children younger than 5 years of age. Case presentation: We present two cases of severe intracranial infections with detected Hia in patients > 5 years of age within a short time frame and within the same geographic area. Conclusion: Epidemiological studies and surveillance on Hia-related illnesses in all age groups worldwide are needed to better understand the clinical and epidemiological characteristics of Hia. This can establish a platform to develop a candidate vaccine against Hia that might protect children of all ages.
