Auditory agnosia progressing to cortical deafness. Long-term follow up of a one-year-old child to age 37.

Background: There are two types of central auditory disorders due to pathology of the bilateral auditory cortices in adult patients: with residual hearing; with total hearing loss. However, long-term changes of hearing acuity over physical development time are unknown.

Objective: The aim of this case report was to illustrate the pathophysiology of auditory changes in a 1 year-3 months old child who was diagnosed with auditory agnosia as a sequel of herpes encephalitis and later developed cortical deafness during a 36-year follow-up.

Unmasking herpes encephalitis masquerading as acute psychosis via neuroimaging.

Psychosis is a complex mental health condition that can have a profound impact on individuals and their families. It is characterized by a loss of contact with reality, including delusions, hallucinations, and disorganized thinking. While psychosis is most commonly associated with psychiatric disorders such as schizophrenia, it is crucial to consider other potential causes to ensure accurate diagnosis and appropriate treatment.

Rhombencephalitis With Long Segment Transverse Myelitis: A Presentation With a Rare Etiology.

Rhombencephalitis is an inflammatory disease affecting the hindbrain (brainstem and cerebellum). The causes of rhombencephalitis can be divided into infections, autoimmune conditions, and paraneoplastic syndrome. Early onset rhombencephalitis is associated with demyelinating disorders or Epstein-Barr virus infection.

Insight Into Uncommon Territory: Exploring Internuclear Ophthalmoplegia in Artery of Percheron Infarct.

Internuclear ophthalmoplegia (INO), a neurological disorder is characterized by horizontal gaze palsy because of a lesion in the medial longitudinal fasciculus, a neural pathway that is mainly responsible for coordinating the movements of the eye. INO presents with diplopia and impaired adduction of the affected eye, accompanied by abducting eye nystagmus. The condition also arises from different etiologies which include multiple sclerosis, encephalitis, Lyme disease, HIV, and herpes zoster.

A Diagnostically Challenging Case of Recurrent Encephalitis With Impending Herniation.

Encephalitis is characterized by inflammation of the brain parenchyma with typical presenting symptoms of altered mental status and seizures. However, diagnostic workup is complex given the multitude of possible etiologies for encephalitis. Further, recurrence of encephalitis is rare, and understanding its risk factors, mechanisms, prognosis, and optimal treatment remains incomplete.

Clinical and Etiological Profile of Children With Acute Viral Encephalitis in a Tertiary Care Hospital: A Cross-Sectional Study.

Background:  Acute encephalitis refers to the clinical diagnosis of children who have a sudden onset of symptoms and show evidence of inflammatory lesions in the brain. Timely diagnosis is crucial for both lifesaving measures and the preservation of brain functions.

Objective:  The objective of the study was to determine the clinical and etiological profile of acute viral encephalitis in children within a tertiary care hospital.

[Cognitive impairment? Don't forget neurolues].

Background: Cognitive disorders usually develop slowly over years and are mainly caused by untreatable neurodegenerative disorders. Rapidly progressive cognitive disorders should raise suspicion of an underlying and treatable psychiatric, internal or neurological condition. Timely recognition of these conditions is important.

A review of HSV pathogenesis, vaccine development, and advanced applications.

Herpes simplex virus (HSV), an epidemic human pathogen threatening global public health, gains notoriety for its complex pathogenesis that encompasses lytic infection of mucosal cells, latent infection within neurons, and periodic reactivation. This intricate interplay, coupled with HSV's sophisticated immune evasion strategies, gives rise to various diseases, including genital lesions, neonatal encephalitis, and cancer. Despite more than 70 years of relentless research, an effective preventive or therapeutic vaccine against HSV has yet to emerge, primarily due to the limited understanding of virus-host interactions, which in turn impedes the identification of effective vaccine targets.

Herpes simplex encephalomyeloradiculitis initially presents with urinary retention.

Herpes simplex virus (HSV) infections necessitate careful management of urinary dysfunction and retention, which are underestimated conditions. Here, we present a rare case of HSV encephalomyeloradiculitis in a 76-year-old man, whose initial symptoms included urinary dysfunction and retention that alone lasted for approximately 1 week. Unlike in meningoencephalitis, high fever and headache were absent; however, the patient subsequently developed cauda equina syndrome and consciousness disturbance.

Using Multiphoton Intravital Microscopy to Study Neutrophil Transmigration and Blood-Brain Barrier Permeability in a Mouse Model of Herpes Simplex Virus Encephalitis.

Multiphoton intravital microscopy (MP-IVM) is an imaging technique used for the observation of living organisms at a microscopic resolution. The tissue of interest is exposed through a window allowing imaging of cells in real time. Using MP-IVM, the temporospatial kinetics of leukocyte transendothelial migration can be visualized and quantitated using reporter mice and cell-specific fluorophore-conjugated monoclonal antibodies to track the leukocytes within and outside of vascular beds.

Specific clinical and radiological characteristics of anti-NMDA receptor autoimmune encephalitis following herpes encephalitis.

Background: Herpes simplex virus encephalitis (HSE) frequently triggers secondary anti-N-methyl-D-aspartate receptor encephalitis (NMDARE), but markers predicting the occurrence of this entity (HSE-NMDARE) are lacking.

Methods: We conducted a retrospective description of patients with HSE-NMDARE diagnosed between July 2014 and August 2022 and compared them to both patients with regular forms of HSE and NMDARE.

Results: Among the 375 patients with NMDARE, 13 HSE-NMDARE were included.

The Rab6 post-Golgi secretory pathway contributes to herpes simplex virus 1 (HSV-1) egress.

Unlabelled: Herpes simplex virus 1 (HSV-1) is an alpha herpesvirus that infects a majority of the world population. The mechanisms and cellular host factors involved in the intracellular transport and exocytosis of HSV-1 particles are not fully understood. To elucidate these late steps in the replication cycle, we developed a live-cell fluorescence microscopy assay of HSV-1 virion intracellular trafficking and exocytosis.
