The influence of targeted therapies in the inner ear.

Scientific research has significantly propelled advancements in healthcare. One notable application is precision medicine, which seeks to analyze and comprehend disease pathology to offer personalized medical treatments to patients. Targeted oncology, a branch of precision medicine, focuses on identifying and targeting specific molecules that regulate cancer cells, thereby minimizing harm to healthy cells. Different types of targeted therapy against cancer include monoclonal antibodies and small molecules. This manuscript intends to provide an overview of the influence of these targeted oncolo

Posture, Gait, Quality of Life, and Hearing with a Vestibular Implant.

BACKGROUND: Bilateral vestibular hypofunction is associated with chronic disequilibrium, postural instability, and unsteady gait owing to failure of vestibular reflexes that stabilize the eyes, head, and body. A vestibular implant may be effective in alleviating symptoms. METHODS: Persons who had had ototoxic (7 participants) or idiopathic (1 participant) bilateral vestibular hypofunction for 2 to 23 years underwent unilateral implantation of a prosthesis that electrically stimulates the three semicircular canal branches of the vestibular nerve. Clinical outcomes included the score on the Bru

Lack of deafness in Crigler-Najjar syndrome type 1: a patient survey.

Transient conductive hearing loss as a notable and rare manifestation of preeclampsia: a case report.

OBJECTIVE: To report a case of transient conductive hearing loss secondary to secretory otitis media (SOM) in a patient with preeclampsia, highlight its unique pathophysiological link, and emphasize the importance of recognizing this potential complication. CASE PRESENTATION: Preeclampsia is a severe, pregnancy-specific multisystem disorder characterized by new-onset hypertension and proteinuria after 20 weeks of gestation. While endothelial dysfunction and vasospasm are central to its pathophysiology, its clinical manifestations are diverse. Auditory dysfunction, particularly conductive hear

Hearing function in patients living with HIV/AIDS.

OBJECTIVES: During the earlier years of the HIV/AIDS epidemic, initial reports described sensorineural hearing loss in up to 49% of individuals with HIV/AIDS. During those years, patients commonly progressed to advanced stages of HIV disease and frequently had neurological complications. However, the abnormalities on pure-tone audiometry and brainstem-evoked responses outlined in small studies were not always consistently correlated with advanced stages of HIV/AIDS. Moreover, these studies could not exclude the confounding effect of concurrent opportunistic infections and syphilis. Additional

[Determination of streptomycin and dihydrostreptomycin in grapes by liquid chromatography-tandem mass spectrometry].

Streptomycin (STR) and dihydrostreptomycin (DSTR) are two of the most common aminoglycoside antibiotics used in veterinary medicine. STR is produced by some streptomyces griseus strains, and DSTR is a derivative of STR. In recent years, STR has been widely used in grapes to induce denuclearization. However, high levels of STR may have adverse effects like serious ototoxicity and nephrotoxicity. Therefore, to ensure the quality of grapes and the health of consumers, the regulation of STR and DSTR levels in grapes is required. An analytical method was developed for the identification and quantif…

Newborn Hearing Screening: Analysing the Effectiveness of Early Detection of Neonatal Hearing Loss in a Hospital in Greece.

Introduction The introduction of newborn hearing screening programs (NHSP) has drastically contributed to the early diagnosis of hearing loss (HL) in children, with the prospect of children developing speech as early as possible. This retrospective study aims to present and discuss the preliminary results of the NHSP at the University Hospital of Patras, Greece, highlighting the strengths and weaknesses of the program. The evaluation of the implementation of NHSP is important to confirm the effectiveness of the process and elaborate system failures. Materials The study describes the results of

Inclusion criteria consisted of being 60 years or older with sensorineural hearing loss and progression o

[Tinnitus in noise-induced hearing impairment].

The analysis of the epidemiological data indicates that exposure to noise is widespread and it is one of the most common causes of tinnitus, estimated at about 20.7% according to Hazell; 28% according to Axelsson; and 42% according to Palmer. Bearing in mind the scantiness of reliable data on the incidence and nature of tinnitus in persons exposed to industrial noise, and especially the need for the objectivity of this subjective symptom, the authors have decided to undertake the study aimed at assessing the interrelation between tinnitus, the magnitude and kind of hearing impairment, and otoa

Effect of N-Acetylcysteine on Cisplatin Toxicity: A Review of the Literature.

N-acetylcysteine (NAC) is a membrane-permeable cysteine precursor capable of enhancing the intracellular cysteine pool, enhancing cellular glutathione (GSH) synthesis, and thus potentiating the endogenous antioxidant mechanism. Late administration of NAC after cisplatin has been shown in different in vivo studies to reduce the side effects caused by various toxicities at different levels without affecting the antitumor efficacy of platinum, improving total and enzymatic antioxidant capacity and decreasing oxidative stress markers. These characteristics provide NAC with a rationale as a potenti

Chemotherapy Side-Effects: Not All DNA Damage Is Equal.

Recent advances have increased survival rates of children and adults suffering from cancer thanks to effective anti-cancer therapy, such as chemotherapy. However, during treatment and later in life they are frequently confronted with the severe negative side-effects of their life-saving treatment. The occurrence of numerous features of accelerated aging, seriously affecting quality of life, has now become one of the most pressing problems associated with (pediatric) cancer treatment. Chemotherapies frequently target and damage the DNA, causing mutations or genome instability, a major hallmark

[A follow-up study of abnormal mutation in neonatal deafness gene screening].

Objective: To screen, diagnose and follow up the abnormal mutation in the gene screening of neonatal deafness. Methods: A total of 24161 newborns born in Zhuhai Maternal and Child Health Hospital from February 1, 2015 to January 31, 2008 were screened for hearing and deafness genes, and audiological screening, diagnosis and 1-3 years follow-up were carried out for the newborns with positive gene screening. Results: There were 991 cases of deafness gene mutation (533 males and 458 females), and the rate of abnormal mutation was 4.10%(991/24 161). Among them, 921 cases were single heterozygous m

Genedrive kit for detecting single nucleotide polymorphism m.1555A>G in neonates and their mothers: a systematic review and cost-effectiveness analysis.

Following feedback from the scoping workshop …

Middle Ear Muscle Reflex and Word Recognition in "Normal-Hearing" Adults: Evidence for Cochlear Synaptopathy?

OBJECTIVES: Permanent threshold elevation after noise exposure, ototoxic drugs, or aging is caused by loss of sensory cells; however, animal studies show that hair cell loss is often preceded by degeneration of synapses between sensory cells and auditory nerve fibers. The silencing of these neurons, especially those with high thresholds and low spontaneous rates, degrades auditory processing and may contribute to difficulties in understanding speech in noise. Although cochlear synaptopathy can be diagnosed in animals by measuring suprathreshold auditory brainstem responses, its diagnosis in hu
