Summary
This case report details a patient with Dengue Hemorrhagic Fever (DHF) who developed sudden sensorineural hearing loss (SSHL). Further research is needed to explore the potential link between dengue infection and hearing impairment.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Virology
Background:
- Dengue Hemorrhagic Fever (DHF) is a severe form of dengue infection characterized by vascular leak syndrome.
- While dengue can manifest with various symptoms, hearing loss is not a commonly recognized manifestation.
- The relationship between viral infections and sudden sensorineural hearing loss (SSHL) is an area of ongoing investigation, with some viruses previously linked to SSHL.
Purpose of the Study:
- To present a case of Dengue Hemorrhagic Fever (DHF) that was complicated by the development of sudden sensorineural hearing loss (SSHL).
- To investigate the potential association between dengue virus infection and SSHL, given the lack of established links.
Main Methods:
- A case report of a 60-year-old male patient diagnosed with Dengue Hemorrhagic Fever (DHF) is presented.
- The patient developed bilateral secretory otitis media and sensorineural hearing loss after the fifth day of symptom onset.
- The hearing loss persisted for over seven months, necessitating referral for hearing aid fitting.
Main Results:
- The patient with DHF developed sudden sensorineural hearing loss (SSHL) during hospitalization.
- No other causes for the sudden hearing loss were identified in this patient.
- The hearing impairment remained significant even after seven months post-onset.
Conclusions:
- This report describes the first documented case of Dengue Hemorrhagic Fever (DHF) co-occurring with sudden sensorineural hearing loss (SSHL).
- The viral theory and vascular theory are discussed as potential mechanisms for SSHL in the context of dengue infection.
- Further research is crucial to establish a definitive correlation between dengue virus and sensorineural hearing loss.

Hemorrhagic Stroke ll: Pathophysiology
3
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Hemorrhagic Stroke l: Introduction
1
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Arboviral Encephalitis
46
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Anatomy of the Ear
14.2K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
