Background: Transsphenoidal surgery is the treatment of choice for Cushing's disease. Successful surgery is associated with subnormal postoperative serum cortisol concentrations and cortisoluria levels, which may guide decisions regarding immediate reoperation. Remission is defined as the biochemical reversal of hypercortisolism with the re-emergence of diurnal circadian rhythm.

Adenoid cystic carcinoma (ACC) is an uncommon malignant neoplasm that predominantly arises from major and minor salivary glands, accounting for about 1% of head and neck malignancies. ACCs originating from the pterygopalatine fossa (PPF) are extremely rare. In this case report, we present a 77-year-old male patient who experienced a two-year hemi-facial numbness and mild trismus, with intact nasal mucosa.

Introduction: Well-differentiated thyroid cancer is among the most common types of endocrine cancer. Despite its increasing prevalence, the prognosis of thyroid cancer is rather good, with a five-year survival rate ranging between 80% and 90%, depending on the histological type. Not only the post-treatment complications and the side effects of the lifelong medication but also the possibility of a recurrence may have a negative impact on the patient's quality of life (QoL).

Background: Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours.

Methods: In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021.

Sinonasal lobular capillary hemangiomas (LCH) are rare benign vascular lesions commonly arising from the nasal septum. Nasopharyngeal, nasal mid-turbinate, and anterior nasal swabbing is the preferred method of screening for coronavirus disease-2019 (COVID-19). Herein, we present a case of a sinonasal LCH in a child after continuous self-tests for COVID-19, with an anterior nasal swab.

Ingestion of foreign bodies is a common entity in emergency clinical practice, especially in the pediatric population. Personal history is rather challenging in these patients, while it is important to accurately define the ingested foreign body. Therefore, the history of a caregiver/eyewitness, physical examination and radiographic findings are taken under consideration.

Objective: High serum erythropoietin (EPO) levels have been reported in adult patients with obstructive sleep apnea (OSA), however there is a lack of related literature in children with OSA. The main objective of this study was to explore the potential use of EPO as a pediatric OSA biomarker by exploring the relationship between serum EPO levels and the presence of pediatric OSA.

Methods And Materials: A prospective study was conducted on children (4-12 years old) referred for overnight PSG.

Middle ear adenomatous neuroendocrine tumors (MEANT) are rare, mainly benign neoplasms and account for less than 2% of the middle and inner ear neoplasms. There are no specific radiological or clinical findings; therefore, the diagnosis is often difficult. Biopsy prior to surgery is often proposed.

Unlabelled: Backround: Radiation-induced oral mucositis consists of a series of relatively frequent side effects after head and neck cancer radiotherapy and has an adverse impact on both regular treatment process and the quality of life of patients.

Objective: The purpose of the present review is to optimize the current management of radiation-induced oral mucositis in head and neck cancer patients.

Methods: PubMed database research was performed on articles published since 2015 that demonstrated efficacy in the management of radiation-induced oral mucositis in head and neck cancer patients.

Unlabelled: Backround: Oral mucositis (OM) consists of a major side effect of radiotherapy (RT) in head and neck (H-N) cancer patients and natural honey is gaining more and more scientific interest due to its beneficial effects in tissue repair.

Objective: The aim of this review is to better clarify the preventive/therapeutic role of honey in the management of OM in patients with H-N cancer undergoing RT with or without chemotherapy (CT).

Methods: We used the PubMed database to retrieve journal articles and the inclusion criteria were only reviews and meta-analyses that illustrated the effective use of honey for either the prevention or treatment of OM in H-N cancer patients receiving either RT alone or in combination with CT.
