The quality and readability of patient information provided by ChatGPT: can AI reliably explain common ENT operations?

PURPOSE: Access to high-quality and comprehensible patient information is crucial. However, information provided by increasingly prevalent Artificial Intelligence tools has not been thoroughly investigated. This study assesses the quality and readability of information from ChatGPT regarding three index ENT operations: tonsillectomy, adenoidectomy, and grommets. METHODS: We asked ChatGPT standard and simplified questions. Readability was calculated using Flesch-Kincaid Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Gunning Fog Index (GFI) and Simple Measure of Gobbledygook (SMOG) scores. We assessed quality using the DISCERN instrument and compared these with ENT UK patient leaflets. RESULTS: ChatGPT readability was poor, with mean FRES of 38.9 and 55.1 pre- and post-simplification, respectively. Simplified information from ChatGPT was 43.6% more readable (FRES) but scored 11.6% lower for quality. ENT UK patient information readability and quality was consistently higher. CONCLUSIONS: ChatGPT can simplify information at the expense of quality, resulting in shorter answers with important omissions. Limitations in knowledge and insight curb its reliability for healthcare information. Patients should use reputable sources from professional organisations alongside clear communication with their clinicians for well-informed consent and making decisions.

Cocaine-associated Eustachian tube stenosis causing chronic 'glue ear': a rare cocaine-induced destructive lesion.

BACKGROUND: Cocaine is one of the most used recreational drugs. Whilst medical uses exist, chronic recreational nasal use of cocaine is associated with progressive destruction of the osseocartilaginous structures of the nose, sinuses and palate - termed cocaine-induced midline destructive lesions. CASE REPORT: A 43-year-old male with a history of chronic cocaine use, presented with conductive hearing loss and unilateral middle-ear effusion. Examination under anaesthesia revealed a completely stenosed left Eustachian tube orifice with intra-nasal adhesions. The adhesions were divided and the hearing loss was treated conservatively with hearing aids. Whilst intra-nasal cocaine-induced midline destructive lesions are a well-described condition, this is the first known report of Eustachian tube stenosis associated with cocaine use. CONCLUSION: This unique report highlights the importance of thorough history-taking, rhinological and otological examination, and audiometric testing when assessing patients with a history of chronic cocaine use. This paper demonstrates the complexity of managing hearing loss in such cases, with multiple conservative and surgical options available.

Post Frenotomy Massage for Ankyloglossia in Infants-Does It Improve Breastfeeding and Reduce Recurrence?

OBJECTIVES: Frenotomy is performed in breast fed infants who experience difficulty in latching after failed conservative management for ankyloglossia or tongue-tie. Though parents sometimes enquire about massage after frenotomy, neither published evidence nor clinical consensus supports this. The aim of our study was to assess if there was significant difference in breast feeding or recurrence rate between those infants who had post frenotomy massage and those who did not. METHODS: A retrospective study was conducted in a tertiary Children's hospital from January 2018 to December 2018. The tongue-tie service consisted of five pediatric surgical consultants, three of whom routinely advice post frenotomy massage. As a result, we had two groups to compare -massage and non-massage group. Total sample size (n = 599) consisted of those who were advised massage (n = 282) and those who were not advised massage (n = 317). RESULTS: Overall recurrence rate was 4/599 (0.66%) and this did not achieve statistical significance between the two groups. Breast feeding rates were also similar in both the groups. However, it is interesting to note that only 43.5% of those advised massage adhered to the massage regimen. CONCLUSIONS: Improvement in breast feeding and recurrence after frenotomy were similar between massage and non-massage groups. This confirms the lack of any additional benefit of post frenotomy massage. This study assists clinicians with decision making not to advise massage as it is unlikely to benefit infants with tongue-tie.

Prevalence of electronegative electroretinograms in a healthy adult cohort.

OBJECTIVE: An electronegative electroretinogram (ERG) can indicate important ocular or systemic disease. This study explored the prevalence of electronegative responses to dark-adapted stimuli in a largely healthy cohort. METHODS AND ANALYSIS: 211 participants recruited from the TwinsUK cohort underwent ERG testing incorporating international standard (International Society for Clinical Electrophysiology of Vision (ISCEV)) protocols and additional stimuli. Responses were recorded using conductive fibre electrodes, following pupil dilation and 20 min dark adaptation. Responses analysed were to the ISCEV standard and strong flashes (3.0 and 10 cd/m2 s), and to additional white flashes (0.67-67 cd/m2 s). A-wave and b-wave amplitudes were extracted; b:a ratios were calculated and proportions of eyes with ratios<1 were noted. RESULTS: Mean (SD) age was 62.4 (11.4) years (median, 64.3; range 23-86 years). 93% were female. Mean (SD) b:a ratios for right and left eyes, respectively, were 1.86 (0.33) and 1.81 (0.29) for the standard flash, and 1.62 (0.25) and 1.58 (0.23) for the stronger flash; average b:a ratio was lower for the stronger flash (p<0.0001). No waveforms were electronegative. For additional flashes, b:a ratio decreased with increasing flash strength. No electronegative waveforms were seen except in three eyes (0.7%) for the strongest flash; in some cases, drift in the waveform may have artefactually reduced the b:a ratio. CONCLUSION: For standard dark-adapted stimuli, no participants had electronegative waveforms. The findings support the notion that electronegative waveforms (in response to standard flash strengths) are unusual, and should prompt further investigation.

Intracranial stimulation for children with epilepsy.

OBJECTIVES: To evaluate the efficacy of intracranial stimulation to treat refractory epilepsy in children. METHODS: This is a retrospective analysis of a pilot study on all 8 children who had intracranial electrical stimulation for the investigation and treatment of refractory epilepsy at King's College Hospital between 2014 and 2015. Five children (one with temporal lobe epilepsy and four with frontal lobe epilepsy) had subacute cortical stimulation (SCS) for a period of 20-161 h during intracranial video-telemetry. Efficacy of stimulation was evaluated by counting interictal discharges and seizures. Two children had thalamic deep brain stimulation (DBS) of the centromedian nucleus (one with idiopathic generalized epilepsy, one with presumed symptomatic generalized epilepsy), and one child on the anterior nucleus (right fronto-temporal epilepsy). The incidence of interictal discharges was evaluated visually and quantified automatically. RESULTS: Among the three children with DBS, two had >60% improvement in seizure frequency and severity and one had no improvement. Among the five children with SCS, four showed improvement in seizure frequency (>50%) and one chid did not show improvement. Procedures were well tolerated by children. CONCLUSION: Cortical and thalamic stimulation appear to be effective and well tolerated in children with refractory epilepsy. SCS can be used to identify the focus and predict the effects of resective surgery or chronic cortical stimulation. Further larger studies are necessary.
