The Role of Fibrinogen, Homocysteine and Metabolic Syndrome's Alterations in Sudden Sensorineural Hearing Loss (SSHL): A Narrative Review.

Fibrinogen and homocysteine (HCY) are molecules known to play a role in vascular homeostasis, and their blood levels are often elevated in patients with metabolic syndrome. Recent evidence suggests that sudden sensorineural hearing loss (SSHL) may have a vascular origin. This has led many authors to advocate that fibrinogen, homocysteine, and metabolic syndrome (MetS) may play a direct role in SSHL. The aim of this brief review is to examine the role and influence of these molecules and MetS on the mechanisms of SSHL. Elevated fibrinogen levels have been associated with a worse prognosis in SSHL, possibly due to increased blood viscosity and decreased blood flow. Similarly, HCY has been associated with vascular damage, particularly in hyperhomocysteinemia, although the exact association with SSHL remains controversial. MetS has been demonstrated to function both as a causative factor and as a contributor to poorer recovery in cases of SSHL. However, although some studies suggest a possible role for these biomarkers and MetS in the prognosis and treatment of SSHL, specific therapeutic and preventive strategies based solely on these factors have yet to be developed. Given their potential role in prognosis and treatment and the global epidemic of metabolic syndrome, this issue needs to be analyzed comprehensively. Thus, further quality studies need to be conducted, even though it is difficult to determine the actual impact of MetS on the development of SSHL, as it is a multifactorial disease affecting multiple organs.

Post-Covid-19 Airway Stenosis: Tracheal Resection-Anastomosis Using The Tritube® Ventilation.

We present a video of a tracheal resection and anastomosis performed on a patient affected by A-shaped tracheal stenosis. The condition was a consequence of a percutaneous tracheostomy following a Sars-Cov2 infection. Airways management during the surgery was obtained with the Tritube®, an innovative device with a very small lumen that combines stable lung parameters and good visualization of surgical field.

Congenital deafness and vestibular disorders: a systematic literature review.

Introduction: Congenital deafness is a pathological entity that represents an economical and social burden, affecting up to 0.2% of newborns in Europe. Sensorineural hearing loss (SHL) is caused by a variety of factors, including congenital abnormalities, perinatal infectious diseases and genetic syndromes. The inner ear's vestibular system, nestled alongside the auditory organs, is crucial for balance maintenance. Its close connection with the auditory system means that disturbances in one often coincide with disturbances in the other, highlighting their intertwined functions. With this review we aim to describe objective vestibular tests found in literature and to study their use for diagnosis of vestibular disturbances in patients affected by congenital deafness. Methods: The review is conducted with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. The search string used was: [(congenital deafness) OR (congenital hearing loss) OR (congenital hypoacusia)] AND [(vestibular disorders) OR (vertigo)]. An initial abstract reading selection was made, and a subsequent comprehensive full-text reading. For each article, we identified the type of vestibular test utilized and its corresponding outcome. Results: Out of the initial-papers identified through the search string-articles met the eligibility criteria for further analysis through abstract and full-text reading. After further selection-articles were chosen for detailed examination, focusing on the data of patients. Conclusion: Congenital hearing loss profoundly affects a child's development, especially in language and communication skills, and it is frequently associated with a pathological vestibular system. Early identification allows timely intervention with personalized therapies. In current literature, there is still no gold standard test to identify balance disorders in patients with congenital hearing loss. There is considerable variability on the subject due to the inclusion of diverse patients with various diagnoses, alongside a wide range of available technologies. Managing such conditions necessitates collaboration among healthcare providers, ensuring comprehensive care through prompt diagnosis and personalized treatment plans. Ongoing research aims to further improve screening methods and develop precision medicine approaches tailored to individual needs.

Oxidized cellulose-based reaction mimicking thyroidal recurrence of disease: a case report and literature review.

Oxidized cellulose is a hemostatic agent currently used in surgery. Foreign body reactions have been described after its use. This paper describes a foreign body reaction caused by oxidized cellulose in a young woman who underwent thyroid surgery. A patient underwent two thyroid surgeries for treatment of papillary carcinoma. Five years after the last surgery, an asymptomatic mass was detected with a routine ultrasound in the left thyroid cavity. After surgical removal, the mass turned out to be a foreign body granuloma based on oxidized cellulose sheets used in the previous surgery. The patient was discharged from the hospital without complications. The follow-up period was uneventful. Oxidized cellulose is a useful tool in surgery to control and prevent intra and post-operative bleeding. Even if it is a biodegradable material, sometimes it persists in the human body causing foreign body reactions that can be misdiagnosed.
