The speed and scale of the global COVID-19 pandemic has resulted in unprecedented pressures on health services worldwide, requiring new methods of service delivery during the health crisis. In the setting of severe resource constraint and high risk of infection to patients and clinicians, there is an urgent need to identify consensus statements on head and neck surgical oncology practice. We completed a modified Delphi consensus process of three rounds with 40 international experts in head and neck cancer surgical, radiation, and medical oncology, representing 35 international professional societies and national clinical trial groups. Endorsed by 39 societies and professional bodies, these consensus practice recommendations aim to decrease inconsistency of practice, reduce uncertainty in care, and provide reassurance for clinicians worldwide for head and neck surgical oncology in the context of the COVID-19 pandemic and in the setting of acute severe resource constraint and high risk of infection to patients and staff.

Purpose To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe. Methods Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion. Results Twenty-four sections on HNC-specific OD topics. Conclusion This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Emergency changes in international guidelines on treatment for head and neck cancer patients during the COVID-19 pandemic On January 30, 2020, the World Health Organization formally announced that the novel coronavirus disease (COVID-19) caused by SARS-CoV-2 is a worldwide health emergency. Subsequently, all National Health Systems and each medical center faced the exceptional emergency and severe changes in their organizations. Consequently, there were various implications that needed to be addressed for oncology patients. In this sense, there are some practical and important issues in the management of head and neck cancer patients: (i) they are usually older and usually present with medical comorbidities (e.g., COPD and other tobacco-related diseases) that are associated with a higher risk of severe complications associated with COVID-19; (ii) high risk of SARS-CoV-2 exposure (transportation, daily radiation fractions, multiple consultations with multidisciplinary team members); (iii) cancer treatment can potentially and theoretically increase the risk of more severe complications of COVID-19 [1]. Of interest, the main risk factors for head and neck squamous cell carcinoma (HNSCC), tobacco and alcohol, also increase the risk for COVID-19 infection. One Chinese study reported an increased risk of cancer-related deaths associated with notorious difficulties of access to oncologic care. In addition, a nationwide analysis in China indicated that the risk of severe respiratory complications leading to admission to the intensive care unit, invasive ventilation, or death was much higher in cancer patients than in patients without cancer (39% vs. 8%, p = 0.0003). Moreover, patients who underwent chemotherapy or surgery in the past month had a numerically higher risk of clinically severe events than did those not receiving chemotherapy or surgery, irrespective of age, smoking history or co-morbidity (odds ratio 5.34, p = 0.0026) [2-5]. The majority of hospitals will be treating thousands of COVID-19 patients in the next few weeks and thus, there is an urgent need to preserve patient and staff safety. For this reason, the Center for Diseases Control (CDC) in the United States recommends that healthcare facilities interrupt elective care and restrict their activities to providing urgent and emergency visits and procedures. It is recommended that all elective and non-time sensitive procedures and admissions must be rescheduled [6]. There is a critical need to share skills and expertise to propose recommendations for the diagnosis and treatment of HNSCC patients throughout the COVID-19 pandemic. As healthcare professionals and HNSCC experts, we aim to offer emergency guidelines aiming to reduce the risk of patient harm, by reducing their risk of exposure to SARS-CoV-2, without compromising their treatment and outcome. As a disclaimer, this is a general guideline and the following recommendations are suggested to help the multidisciplinary teams in the diagnosis and treatment of HNSCC patients, considering local constraints...

Aim: To study Wolfram syndrome (WFS) with multidisciplinary consultations and compare the results with the literature. Methods: Nine patients fulfilled the ascertainment criteria of WFS (insulin-dependent diabetes mellitus and optic atrophy). All patients were evaluated by the departments of paediatrics, ophthalmology, audiology, urology and medical biology. Results: The earliest manifestation of WFS was insulin-dependent diabetes mellitus (at a median age of 6.9 y), followed by optic atrophy (8.9 y), diabetes insipidus (10.2 y) and deafness (10.5 y). Short stature was found in five cases, delayed puberty in two cases and hypergonadotropic hypogonadism in one case. Audiography disclosed hearing loss at high frequency in all patients (100%), but only five patients had clinical subjective hearing problems. Intravenous pyelography revealed hydroureteronephrosis in eight patients. Urodynamics revealed a normal bladder in only one patient. Three patients had a low-capacity, low-compliance bladder, detrusor external sphincteric dyssynergia and emptying problem, while five had an atonic bladder. Ocular findings were optic atrophy, low visual acuity and colour vision defects. Visual field tests revealed concentric and/or peripheral diminution in five patients. Visual evoked potentials were abnormal (reduced amplitude to both flash and pattern stimulation) in seven patients. Cranial magnetic resonance imaging showed mild or moderate atrophy of the optic nerves, chiasm, cerebellum, basal ganglia and brainstem in six patients; there was a partially empty sella in one case. There was no evidence of mitochondrial tRNA Leu (UUR) A to G (nucleotide 3243) mutation.Conclusion: Wolfram syndrome should be evaluated in a multidisciplinary manner. Some specific and dynamic tests are necessary to make a more precise estimate of the prevalence and median age of the components of WFS. Short stature is a common feature in WFS. Hypogonadism may be hypogonadotropic or hypergonadotropic. Bladder dysfunction does not always present as a large atonic bladder in WFS. A low-capacity, high-pressure bladder with sphincteric dyssynergia is also common.
