Utility and limitations of metabolic parameters in head and neck cancer: finding a practical segmentation method.

Purpose: Although metabolic tumor volume (MTV) and total lesion glycolysis (TLG) have shown good prognostic value in head and neck cancer (HNC), there are still many issues to resolve before their potential application in standard clinical practice. The purpose of this study was to compare the discrimination ability of two relevant segmentation methods in HNC and to evaluate the potential benefit of adding lymph nodes' metabolism (LNM) to the measurements.

Methods: We retrospectively analyzed a recently published database of 62 patients with HNC treated with chemoradiotherapy.

Chemosensory dysfunction in COVID-19 out-patients.

Background: Since the outbreak in China due to coronavirus disease 2019 (COVID-19) various studies have been published describing olfactory and gustatory dysfunction (OGD).

Objective: The aim was to investigate the frequency and severity of OGD in SARS-CoV-2 (+) out-patients compared to controls with common cold/flu like symptoms and two negative RT-PCR.

Methods: A multicenter cross-sectional study on SARS-CoV-2-positive out-patients (n = 197) and controls (n = 107) from five Spanish Hospitals.

Olfactory and taste disorders in healthcare workers with COVID-19 infection.

Purpose: Severe acute respiratory syndrome caused by COVID-19 has spread globally for the last few months. Healthcare workers (HCW) are overexposed and infection rates are higher than in the rest of the population. Strict clinical assessment is paramount to detect suspicious cases.

Ethyl alcohol threshold test: a fast, reliable and affordable olfactory Assessment tool for COVID-19 patients.

Objective: COVID-19 patients may present mild symptoms. The identification of paucisymptomatic patients is paramount in order to interrupt the transmission chain of the virus. Olfactory loss could be one of those early symptoms which might help in the diagnosis of COVID-19 patients.

Extended high frequency audiometry can diagnose sub-clinic involvement in a seemingly normal hearing systemic lupus erythematosus population.

Conclusions: Sensorineural hearing loss must be considered within the clinical picture of systemic lupus erythematosus. The results confirm the usefulness of extended high-frequency audiometry in the audiologic testing of these patients, enabling the possibility of modifying or applying a preventive treatment for a possible hearing loss.

Objectives: Hearing involvement is usually under-diagnosed with routine auditory examination.

Examination of Hearing in a Rheumatoid Arthritis Population: Role of Extended-High-Frequency Audiometry in the Diagnosis of Subclinical Involvement.

Objective. The aim of this study is to analyze the high-frequency hearing levels in patients with rheumatoid arthritis and to determine the relationship between hearing loss, disease duration, and immunological parameters. Materials and Methods.

Promising Technique for Facial Nerve Reconstruction in Extended Parotidectomy.

Introduction: Malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. Most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. Although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection.

Eosinophilic esophagitis: A relevant entity for the otolaryngologist.

Eosinophilic esophagitis (EE) is a recently recognised pathologic entity whose prevalence has risen significantly since it was first described. Its diagnosis represents a challenge for different medical specialties, among which ENT specialists play an important role. Clinical suspicion in a patient with recurrent food impaction or a child with eating disorders and history of hypersensitivity constitutes the first warning sign of a possible EE.

Noncholesteatomatous Cyst of the Tympanic Membrane: A Nonpublished Entity?

Introduction. The presence of a serous cyst in the tympanic membrane implies the description of a new or unpublished entity based on our knowledge whose origin may be very unlikely explained on actual embryologic and anatomic background. Clinical Case.

Extended high-frequency audiometry (9,000-20,000 Hz). Usefulness in audiological diagnosis.

Early detection and appropriate treatment of hearing loss are essential to minimise the consequences of hearing loss. In addition to conventional audiometry (125-8,000 Hz), extended high-frequency audiometry (9,000-20,000 Hz) is available. This type of audiometry may be useful in early diagnosis of hearing loss in certain conditions, such as the ototoxic effect of cisplatin-based treatment, noise exposure or oral misunderstanding, especially in noisy environments.

Hemangiopericytoma of the parapharyngeal space: a diagnostic challenge.

Parapharyngeal space tumors are known for having a difficult approach, misleading diagnosis and for representing a treatment challenge. Hemangiopericytomas account for less than 1% of all vascular neoplasms and 3% of all soft tissue sarcomas. Only 14 cases have been reported in the worldwide literature in this location.
