Tuberculosis (TB) is a significant global health issue, predominantly affecting the lungs but also capable of involving the otorhinolaryngologic (ear, nose, and throat) regions. This comprehensive review explores the epidemiology, pathophysiology, clinical presentation, diagnostic challenges, management strategies, and public health implications of otorhinolaryngologic TB. The disease's diverse clinical manifestations, such as chronic ear discharge, nasal obstruction, and hoarseness, often mimic other common conditions, complicating diagnosis and delaying treatment. Diagnostic confirmation requires a combination of clinical assessment, laboratory tests, and imaging techniques, each with inherent limitations. Effective management necessitates a multidisciplinary approach, integrating medical and surgical interventions tailored to individual patient needs. Potential complications, including airway obstruction and hearing loss, highlight the importance of timely and appropriate treatment. The review underscores the critical role of public health measures in TB control. It also identifies emerging trends in diagnosis and treatment, emphasizing the need for ongoing research to improve patient outcomes and contribute to the global effort to control and eventually eradicate TB. This review aims to give healthcare providers a deeper understanding of otorhinolaryngologic TB, enhancing diagnostic and therapeutic approaches and improving patient care., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Pleural metastatic melanoma is rare, and associated malignant pleural effusions are even rarer. We present a case of pleural metastatic melanoma with recurrent malignant pleural effusions. The initial diagnosis showed no metastatic disease, and the patient underwent resection and received a year of immunotherapy for localized disease. However, two years later, the patient presented with pleural metastatic melanoma with unresolving malignant pleural effusions requiring an indwelling pleural catheter and eventually, thoracotomy with decortication. Clinicians should have a high index of suspicion for pleural metastatic melanoma in the setting of recurrent pleural effusions, even though it is a rare occurrence., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Vallecular cysts (VCs) are rare benign lesions arising from the obstruction of mucous gland ducts. VCs are uncommon anomalies found in both pediatric and adult populations. They are also known as mucous-retention cysts, preepiglottic cysts, ductal cysts, base-of-tongue cysts, and epiglottis cysts. VCs are often asymptomatic in adults and may present with nonspecific symptoms such as globus sensation, voice changes, dysphagia, hoarseness, or airway obstruction when symptomatic. This case report details a rare occurrence of a giant VC in an adult male, emphasizing the diagnostic approach and surgical management and highlighting the importance of managing the airway in such cases and the advantages of endoscopic procedures., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

The classical view of the renin-angiotensin system (RAS) is that of the circulating hormone pathway involved in salt and water homeostasis and blood pressure regulation. It is also involved in the pathogenesis of cardiac and renal disorders. This led to the creation of drugs blocking the actions of this classical pathway, which improved cardiac and renal outcomes. Our understanding of the RAS has significantly expanded with the discovery of new peptides involved in this complex pathway. Over the last two decades, a counter-regulatory or protective pathway has been discovered that opposes the effects of the classical pathway. Components of RAS are also implicated in the pathogenesis of obesity and its metabolic diseases. The continued discovery of newer molecules also provides novel therapeutic targets to improve disease outcomes. This article aims to provide an overview of an updated understanding of the RAS, its role in physiological and pathological processes, and potential novel therapeutic options from RAS for managing cardiorenal disorders, obesity, and related metabolic disorders., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Kanugula et al.)
