The Effects of Memantine on Cisplatin-Induced Ototoxicity.

Audiol Neurootol

November 2024

Department of Otorhinolaryngology, Head and Neck Surgery, Koç University Faculty of Medicine, Istanbul, Turkey.

Introduction: We aimed to investigate electrophysiologically and histopathologically, the protective effects of intratympanic memantine, an N-methyl-D-aspartate receptor antagonist, on ototoxicity caused by cisplatin, an anti-neoplastic agent used in many types of cancer.

Methods: Thirty-seven guinea pigs with a normal auditory function were randomly allocated to group 1 (cisplatin; n = 8), group 2 (memantine; n = 8), group 3 (cisplatin + memantine; n = 8), group 4 (cisplatin + physiological serum [PS]; n = 8), and group 5 (control; n = 5). Auditory assessments were conducted using distortion product otoacoustic emissions (DPOAE) within a frequency range of 1-32 kHz and auditory brainstem responses (ABRs) within 8-32 kHz.

Purpose: This study aimed to evaluate the validity of two artificial intelligence (AI)-based bone age assessment programs, BoneXpert and VUNO Med-Bone Age (VUNO), compared with manual assessments using the Greulich-Pyle method in Turkish children.

Methods: This study included a cohort of 292 pediatric cases, ranging in age from 1 to 15 years with an equal gender and number distribution in each age group. Two radiologists, who were unaware of the bone age determined by AI, independently evaluated the bone age.

Article Synopsis
  • The study aimed to evaluate the effectiveness of stereotactic body radiotherapy (SBRT) on patients with oligometastatic colorectal cancer (CRC) and its impact on survival and local control rates.
  • A total of 388 patients with up to 5 metastatic lesions were analyzed, showing that most had previously undergone surgery and had limited organ involvement, with median follow-up of about 30.7 months.
  • Results indicated that higher SBRT doses (≥100 Gy) significantly improved local control, progression-free survival, and overall survival rates, highlighting SBRT as a promising treatment for metastatic CRC.

Article Synopsis
  • This study assessed whether the RECIST criteria for objective response rates (ORR) could predict long-term overall survival (OS) in metastatic urothelial carcinoma patients undergoing immune checkpoint inhibitor (ICI) therapy.
  • The analysis revealed that 47% of patients had disease progression within the first 3 months, with complete response (CR) seen in 10%, partial response (PR) in 23%, and stable disease (SD) in 20% of cases.
  • Key findings showed that 5-year OS rates significantly favored CR (73%) over PR (23%), and certain factors like liver metastases and response type were critical indicators of OS, highlighting the relevance of ORR as a potential surrogate endpoint.

The proposed expert opinion aimed to address the current knowledge on conceptual, clinical, and therapeutic aspects of diabetic peripheral neuropathy (DPN) and to provide a guidance document to assist clinicians for the best practice in DPN care. The participating experts consider the suspicion of the disease by clinicians as a key factor in early recognition and diagnosis, emphasizing an improved awareness of the disease by the first-admission or referring physicians. The proposed "screening and diagnostic" algorithm involves the consideration of DPN in a patient with prediabetes or diabetes who presents with neuropathic symptoms and/or signs of neuropathy in the presence of DPN risk factors, with careful consideration of laboratory testing to rule out other causes of distal symmetric peripheral neuropathy and referral for a detailed neurological work-up for a confirmative test of either small or large nerve fiber dysfunction in atypical cases.
