Vestibular paroxysmia

Vestibular paroxysmia is a rare vestibular disorder in which short attacks of vertigo, up to 30 or more per day, are attributed to neurovascular compression of the eighth cranial nerve.

Vestibular rehabilitation (VRT, vestibular physical therapy) is exercise-based physical therapy for peripheral vestibular hypofunction, using gaze stabilization, habituation, balance and gait exercises; strong guideline evidence supports it, unlike isolated eye-movement exercises.

Vestibular schwannoma

Vestibular schwannoma (acoustic neuroma) is a benign Schwann-cell tumor of the vestibulocochlear nerve causing unilateral hearing loss, tinnitus, and imbalance; managed by observation, radiosurgery, or microsurgery, with bilateral tumors signaling NF2.

Vestibular schwannoma resection

Vestibular schwannoma resection, often called acoustic neuroma removal, is a neurosurgical operation performed through translabyrinthine, retrosigmoid, or middle cranial fossa corridors, with stereotactic radiosurgery as a non-invasive alternative.

Vestibular stimulation

Vestibular stimulation activates the inner-ear balance organs by caloric, galvanic, or rotational means, to test vestibular function or treat balance disorders; caloric testing was first described by Robert Bárány.

Vestibular system

The vestibular system, or labyrinth, is the inner-ear sensory system detecting head motion and gravity via three semicircular canals and the utricle and saccule, enabling balance, gaze stabilization (VOR), and spatial orientation; disorders cause vertigo and imbalance.

Vestibulo–ocular reflex

Vestibulo–ocular reflex (VOR, oculovestibular reflex): automatic eye reflex stabilizing vision during head motion, gain normally 1, tested by head impulse, vHIT, caloric, and rotary chair tests.

Vestibulocochlear nerve

Vestibulocochlear nerve (CN VIII, acoustic nerve): purely sensory eighth cranial nerve carrying hearing from the cochlea and balance from the vestibular organs through the internal auditory canal to brainstem nuclei.

Vestibuloplasty

Vestibuloplasty is a surgical procedure on the soft tissue of the upper or lower jaw that deepens the oral vestibule to improve denture retention and stability.

Vestronidase alfa

Vestronidase alfa (Mepsevii, UX003, vestronidase alfa-vjbk) is a recombinant human beta-glucuronidase enzyme replacement therapy for mucopolysaccharidosis VII, dosed 4 mg/kg IV every other week, FDA approved 2017.

Veterans Health

Veterans Health (MeSH D058014): the physical and mental health conditions of military veterans, delivered mainly through the U.S. Veterans Health Administration, the largest integrated health system, with quality comparisons, community care, and research.

Veverimer

Veverimer (TRC101) is Tricida's oral, non-absorbed hydrochloric acid binder for metabolic acidosis in CKD; it raised bicarbonate in early trials but the VALOR-CKD Phase 3 renal outcomes trial missed its primary endpoint.

VEXAS syndrome

VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is an adult-onset autoinflammatory disorder caused by somatic UBA1 mutations in hematopoietic stem cells, affecting mostly men over 50 with fever, skin lesions, chondritis, macrocytic anemia, and MDS overlap.

VFHCS study

The Vicente Ferrer HIV Cohort Study (VFHCS) is a long-term cohort study of HIV patients at Rural Development Trust hospitals in Anantapur district, Andhra Pradesh, India, running since 2009.

VGR-R01 (CYP4V2 AAV8 gene therapy)

VGR-R01 (rAAV2/8-CYP4V2) is Shanghai Vitalgen's subretinal AAV8 gene therapy delivering codon-optimized human CYP4V2 for Bietti crystalline dystrophy; phase 1/2 showed BCVA gains, phase 3 completed, NDA accepted by China CDE in June 2026.

VIBE-FGS study

VIBE-FGS (VIBE-FGS-EUSAN, NCT01154907) was an EU FP7 consortium led by Oslo University Hospital studying praziquantel prevention of female genital schistosomiasis and HIV risk in 2,293 adolescent girls in KwaZulu-Natal, South Africa, 2011–2016.

Vibostolimab

Vibostolimab (MK-7684) was Merck's humanized anti-TIGIT IgG1 antibody for cancer, tested as the MK-7684A coformulation with pembrolizumab; phase 3 futility ended development in December 2024.

Vibozilimod

Vibozilimod (SCD-044) was an oral S1PR1 agonist developed by SPARC with Bioprojet and licensed to Sun Pharma for psoriasis and atopic dermatitis; both Phase 2 SOLARES trials missed primary endpoints in June 2025 and development was discontinued.

VIBRAMOT trial

VIBRAMOT (NCT04504214) is a Paris-based randomized pilot trial of 80 Hz tendon vibration at the elbow and wrist, two 15-minute sessions daily for 10 days, to improve upper limb motor recovery within 60 days of stroke, measured by motor evoked potentials.

Vibration therapy

Vibration therapy applies mechanical oscillations to the whole body or a single muscle to treat musculoskeletal, neurological, and circulatory conditions, including sarcopenia, osteoporosis, and spasticity.

Vibratory urticaria

Vibratory urticaria (dermodistortive urticaria, VBU): rare physical urticaria in which vibration, stretching, or friction of skin triggers hives, swelling, and itching within minutes; familial cases linked to autosomal dominant ADGRE2 mutation.

Vici syndrome

Vici syndrome (OMIM 242840, Dionisi-Vici-Sabetta-Gambarara syndrome) is a rare autosomal recessive multisystem disorder caused by EPG5 mutations on 18q12.3, marked by callosal agenesis, cataracts, cardiomyopathy, combined immunodeficiency, and hypopigmentation.

VICIS study

VICIS (Vienna Cirrhosis Study), NCT03267615, is a prospective observational cohort and biobank of advanced chronic liver disease patients at Medical University of Vienna, following up to 10,000 adults for transplant-free and decompensation-free survival.

Vicki Belo

Vicki Belo, also known as Victoria G. Belo, is a Filipino dermatologist, born 1957, who pioneered medical aesthetics in the Philippines; her Belo Medical Group operates 14 clinics.

Vicks

Vicks (VapoRub, VapoRub ointment) is a Procter & Gamble brand of OTC cough, cold, flu, and sleep remedies founded by Lunsford Richardson in Greensboro, NC in 1894; acquired by P&G in 1985 and the global No.1 consumer healthcare brand.

Vicks VapoRub

Vicks VapoRub, also called VapoRub, is a camphor-menthol-eucalyptus chest rub created in 1894 by pharmacist Lunsford Richardson, named in 1911, and made by Procter & Gamble since 1985.
