Nasopharyngeal carcinoma (NPC) is an aggressive head and neck cancer characterized by Epstein-Barr virus (EBV) infection and dense lymphocyte infiltration. The scarcity of NPC genomic data hinders the understanding of NPC biology, disease progression and rational therapy design. Here we performed whole-exome sequencing (WES) on 111 micro-dissected EBV-positive NPCs, with 15 cases subjected to further whole-genome sequencing (WGS), to determine its mutational landscape. We identified enrichment for genomic aberrations of multiple negative regulators of the NF-κB pathway, including CYLD, TRAF3, NFKBIA and NLRC5, in a total of 41% of cases...

A 35-year-old man was admitted to an intensive care unit with unilateral facial swelling and septic shock after multiple presentations to the emergency department with non-specific unilateral pain over the parotid area. A CT scan of his neck showed diffuse right-sided facial soft tissue infection, mastoid effusion and temporal lobe cerebritis. The upper lobes of his lungs had cannonball lesions that were suggestive of septic lung metastases. Blood cultures and ear canal swabs were positive for Burkholderia pseudomallei The temporal lobe cerebritis eventually developed into an abscess, necessitating a cortical mastoidectomy, craniectomy and temporal lobectomy...

Posttraumatic headaches usually have tension-type or migraine-like characteristics. A correlation between head trauma and cluster headaches (CH) has been previously reported. CH in children are rare and require thorough differential diagnosis. We present an original case of a 15-year-old boy with cluster headaches associated with allodynia probably evoked by a neck trauma. Severe headache attacks started one month after neck trauma. At the beginning clinical presentation of our patient's headaches was very misleading...

Mediastinitis continues to be an important and life-threatening complication after median sternotomy despite advances in prevention and treatment strategies, with an incidence of 0.25-5%. It can also occur as extension of infection from adjacent structures such as the oesophagus, airways and lungs, or as descending necrotizing infection from the head and neck. In addition, there is a chronic form of 'chronic fibrosing mediastinitis' usually caused by granulomatous infections. In this expert consensus, the evidence for strategies for treatment and prevention of mediatinitis is reviewed in detail aiming at reducing the incidence and optimizing the management of this serious condition...

: Pediatric radial neck fractures are uncommon. Severely displaced and angulated fractures usually require treatment. Our goals for treatment are to avoid incision, reduce the fracture adequately with no reduction loss, and achieve good postoperative function. We aimed to observe the clinical outcomes of closed reduction with the percutaneous leverage technique and internal fixation with Kirschner-wires (K-wires) to treat angulated radial neck fractures in children.From January 2011 to April 2013, we treated 16 cases of angulated radial neck fracture in 12 boys and 4 girls...

The assessment of tumor infiltrating lymphocytes (TILs) has recently emerged as a prognostic biomarker in several solid tumors. Quantification and subtyping of TILs reflects the immune response in the tumor microenvironment, contributing to either tumoral immune attack or escape and thereby affecting outcome. Despite the growing evidence of its value as prognosticator, TILs analysis has not yet found its way to daily clinical practice. The aim of this review is to evaluate whether the current knowledge on TILs in head and neck cancer justifies its clinical implementation...

The landscape of HPV infection in racial/ethnic subgroups of head and neck cancer (HNC) patients has not been evaluated carefully. In this study, a meta-analysis examined the prevalence of HPV in HNC patients of African ancestry. Additionally, a pooled analysis of subject-level data was also performed to investigate HPV prevalence and patterns of p16 (CDNK2A) expression amongst different racial groups. Eighteen publications (N = 798 Black HNC patients) were examined in the meta-analysis, and the pooled analysis included 29 datasets comprised of 3,129 HNC patients of diverse racial/ethnic background...

PURPOSE: Human papillomavirus (HPV) 16 plays an etiologic role in a growing subset of HNSCCs, where viral expression of the E6 and E7 oncoproteins are necessary for tumor growth and maintenance. Although patients with HPV(+) tumors have a more favorable prognosis, there are currently no HPV-selective therapies. Recent studies identified differential receptor tyrosine kinase (RTK) profiles in HPV(+) vs. HPV(-) tumors. One such RTK, HER3, is overexpressed and interacts with phosphoinositide 3-kinase (PI3K) in HPV(+) tumors...

There is emerging evidence of the association between human papillomavirus and a subset of head and neck cancers. However, the role of human papillomavirus as a causal factor is still debated. This review addresses the association between human papillomavirus and oropharyngeal squamous cell carcinoma using the Bradford Hill criteria. The strength of the association is supported by, detection of human papillomavirus infection and antibodies prior to oropharyngeal squamous cell carcinoma. This is furthermore reinforced by the absence of human papillomavirus DNA in healthy tonsils...

Human papillomavirus (HPV) is known to be a necessary factor for many gynecologic malignancies and is also associated with a subset of head and neck malignancies. This knowledge has created the opportunity to control these HPV-associated cancers through vaccination. However, despite the availability of prophylactic HPV vaccines, HPV infections remain extremely common worldwide. In addition, while prophylactic HPV vaccines have been effective in preventing infection, they are ineffective at clearing pre-existing HPV infections...

Importance: Pathology-based measures of human papillomavirus (HPV) status are routinely obtained in the care of head and neck cancer and are clearly associated with patient outcome for cancers of the oropharynx. However, it is unclear if HPV status is of high value for cancers of the larynx and oral cavity. In addition, it is possible to assess HPV infection using serology-based methods; however, the suitability of this pathology-independent measure for predicting patient outcome in head and neck cancer is unknown...

Importance: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) has a favorable prognosis, and p16 immunohistochemistry is a surrogate marker of high-risk HPV infection and strong prognosticator. Given this favorable prognosis, treatment de-escalation for p16-positive OPSCC is now being considered with the goal of decreasing treatment-associated morbidity without compromising tumor control. The role of adjuvant chemotherapy in this setting is becoming increasingly unclear...
