An automated approach for real-time informative frames classification in laryngeal endoscopy using deep learning.

PURPOSE: Informative image selection in laryngoscopy has the potential for improving automatic data extraction alone, for selective data storage and a faster review process, or in combination with other artificial intelligence (AI) detection or diagnosis models. This paper aims to demonstrate the feasibility of AI in providing automatic informative laryngoscopy frame selection also capable of working in real-time providing visual feedback to guide the otolaryngologist during the examination. METHODS: Several deep learning models were trained and tested on an internal dataset (n = 5147 images) and then tested on an external test set (n = 646 images) composed of both white light and narrow band images. Four videos were used to assess the real-time performance of the best-performing model. RESULTS: ResNet-50, pre-trained with the pretext strategy, reached a precision = 95% vs. 97%, recall = 97% vs, 89%, and the F1-score = 96% vs. 93% on the internal and external test set respectively (p = 0.062). The four testing videos are provided in the supplemental materials. CONCLUSION: The deep learning model demonstrated excellent performance in identifying diagnostically relevant frames within laryngoscopic videos. With its solid accuracy and real-time capabilities, the system is promising for its development in a clinical setting, either autonomously for objective quality control or in conjunction with other algorithms within a comprehensive AI toolset aimed at enhancing tumor detection and diagnosis.

Otorhinolaryngological manifestations in monkeypox.

BACKGROUND AND OBJECTIVE: In the current health emergency declared by the World Health Organization (WHO) for monkeypox, few data on the otorhinolaryngological (ENT) manifestations of the disease have been detailed. The purpose of this study is to describe the clinical features of the ENT manifestations in monkeypox. MATERIALS AND METHODS: Descriptive analysis of 11 consecutive patients with odynodysphagia or oral cavity lesions referred to the ENT emergency department of a tertiary hospital with epidemiological risk factors suggestive of monkeypox infection. Clinical, diagnostic and treatment findings are described. RESULTS: 90.9% of the patients had previous unsafe sexual contact. The predominant presenting features included fever over 38 °C with severe odynodysphagia. Physical examination showed ulcers and exudative lesions of variable presentation in the upper respiratory tract. Smear of the lesions confirmed polymerase chain reaction (PCR) positivity for monkeypox in all patients. CONCLUSIONS: Monkeypox virus infection can occur in the ENT area with multiple manifestations that require a high degree of epidemiological suspicion and confirmation with PCR to reach a diagnosis of certainty.

The Achilles Tendon Rupture in Basketball: Systematic Review of the Present Literature.

Background The most common cause of the Achilles tendon ruptures in the U.S. population is sports, basketball is one among them. It is not one of the most frequent injuries of this sport, but it is one of the most serious and impactful in its practice. Purpose The objective of this work is to gather evidence and evaluate the relationship between Achilles' tendon ruptures and basketball. Study Design This study designed as a systematic review. Material and Methods A search of literature in the databases PubMed, Cochrane Library, and ClinicalTrials.gov was conducted during January and February 2020. Results After the search and selection, three relevant articles were obtained due to their epidemiological content, Raikin et al and Lemme et al. In 2013 and 2018, they, respectively, conducted studies in U.S. populations, establishing sport as the most frequent injury mechanism in Achilles' tendon ruptures. It was analyzed according to injury mechanism, gender, body mass index (BMI), and age. In both studies, the lesion resulted more frequently in men and the sport involved in most of the cases was basketball (32 and 42.6%, respectively). In 2019, Lemme et al published an epidemiological design analyzing the Achilles tendon ruptures in the National Basketball Association (NBA), identifying risk factors and results in professional players. After suffering the injury, 36.8% of the patients had to retire or were holders in less than 10 games to the rest of their sports career. Conclusions The relationship between basketball and Achilles' tendon rupture is clear in the general population. Despite this, new studies are required to complement the evidence obtained so far.
