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.

Manifestaciones otorrinolaringológicas en la viruela del mono / Otorhinolaryngological manifestations in monkeypox

Antecedentes y objetivo En la actual emergencia sanitaria declarada por la Organización Mundial de la Salud (OMS) por viruela del mono se han detallado pocos datos sobre las manifestaciones otorrinolaringológicas (ORL) de dicha enfermedad. El propósito del estudio pretende describir las características clínicas de las manifestaciones ORL de la viruela del mono. Material y métodos Análisis descriptivo de 11 pacientes consecutivos con odinodisfagia o lesiones de la cavidad oral derivados al área de urgencias de ORL de un hospital terciario con factores de riesgo epidemiológicos que pudieran sugerir infección por viruela del mono. Se describen los hallazgos clínicos, diagnósticos y de tratamiento. Resultados El 90,9% de los pacientes habían tenido contacto sexual de riesgo previo. El cuadro de presentación predominante incluía fiebre de más de 38°C con odinodisfagia intensa. El examen físico mostraba úlceras y lesiones exudativas de presentación variable en la vía aerodigestiva superior. El frotis de las lesiones confirmó positividad en la reacción en cadena de la polimerasa (PCR) para viruela del mono en todos los pacientes. Conclusiones La infección por virus de viruela del mono puede presentarse en el área ORL con múltiples manifestaciones que precisan de un grado de sospecha epidemiológico alto y la confirmación con PCR para llegar a un diagnóstico de certeza.

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. Material 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.
