“…A sensory neural type of hearing loss has been reported in patients infected with Rickettsia rickettsii ( R. rickettsii), R. typhi or R. coronii [6-8]. Although the mechanism of hearing loss in scrub typhus has not yet been elucidated, at least two mechanisms have been proposed.…”

“…Although the mechanism of hearing loss in scrub typhus has not yet been elucidated, at least two mechanisms have been proposed. In the first, the rickettsiae directly invade the central nervous system and induce vasculitis in the acute stage, and this damages the cochlear division of the eighth cranial nerve [6,11,12]. In the second, vasculitis is produced in the vasa vasorum of the cochlear nerve by a secondary immune mechanism.…”

“…Complications include pneumonia, myocarditis, meningitis, hepatitis, acute renal failure and hearing loss [3-5]. A sensory neural type of hearing loss has been reported in patients infected with Rickettsia rickettsii ( R. rickettsii), R. typhi or R. coronii [6-8]. Hearing loss described in scrub typhus infected patients is rare in Korea.…”

BackgroundScrub typhus is an acute febrile illness caused by Orientia tsutsugamushi.Case presentationsWe encountered a patient with sensorineural hearing loss complicating scrub typhus, and three patients with scrub typhus who complained of otalgia, which was sudden onset, severe, paroxysmal, intermittent yet persistent pain lasting for several seconds, appeared within 1 week after the onset of fever and rash. The acute sensorineural hearing loss and otalgia were resolved after antibiotic administration.ConclusionWhen patients in endemic areas present with fever and rash and have sensorineural hearing loss or otalgia without otoscopic abnormalities, clinicians should suspect scrub typhus and consider empirical antibiotic therapy.

“…The second mechanism is by vasculitis in the vasa vasorum of the cochlear nerve by a secondary immune mechanism. [7][8][9] Premratna et al report that deafness appears in the second week of the disease. In our patient, hearing loss was reported around the 11th day of the disease.…”

BACKGROUNDScrub typhus, also known as bush typhus is an acute, febrile illness caused by trombiculid mites. The disease is endemic to Southeast Asia and Northern Australia and derives its name from the vegetation that harbours the mite. The causative organism is Orientia tsutsugamushi, a gram negative alpha proteobacterium. The patient usually presents with high-grade fever, an eschar at the inoculation site, generalised lymphadenopathy, organomegaly and pneumonitis. Rarely, the patient may go into acute renal failure, disseminated intravascular coagulation and shock. Sudden sensorineural hearing loss during the course of the disease is a very uncommon presentation and is usually reversible with empirical treatment.

“…31 Viruses linked to SNHL that may present with unilateral hearing loss include varicella zoster, measles, mumps, rubella, and cytomegalovirus. Other infections include syphilis 53 and tick-borne infections such as Rocky Mountain spotted fever 81,82 (caused by Rickettsia rickettsii) and Lyme disease 83 (caused by Borrelia burgdorferi).…”

Unilateral sensorineural hearing loss (SNHL) affects people at any age, can present as an acute and/or progressive process, and can range from mild to profound. Although the great majority of cases have an unknown cause, the known causes of unilateral SNHL need to be excluded including neoplasms, stroke, demyelinating and autoimmune diseases, infection, perilymphatic fistula, and Ménière's disease. The majority of individuals with idiopathic sudden SNHL will recover complete or partial hearing. However, there is a small subset of patients who remain with unilateral hearing impairment, which can result in communication difficulties. The goal of this article is to present the etiology and medical management of unilateral SNHL in the adult population.KEYWORDS: Baha (bone-anchored hearing aid), CROS (contralateral routing of the signal), single-sided deafness, unilateral sensorineural hearing loss Learning Outcomes: As a result of this activity, the participant will be able to (1) list possible etiologies of unilateral sensorineural hearing loss (SNHL) in adults, and (2) list management options for adults with unilateral SNHL.
