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...

BACKGROUND: The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass...

BACKGROUND: A portable disposable ultrathin endoscope (DUE) with high visual quality and maneuverability would reduce the need for expensive facilities and emergency endoscopy could be available anywhere. It would increase patient satisfaction, prevent unnecessary sedation, and reduce infection. Our aim was to evaluate the usefulness of portable DUE in performing percutaneous endoscopic gastrostomy (PEG). METHODS: We prospectively enrolled patients who underwent PEG under DUE guidance and compared them with historical controls who underwent PEG under conventional ultrathin endoscopy (CUE) guidance...

Head and neck squamous cell carcinoma (HNSCC) is the sixth leading cause of cancer worldwide. The treatment of choice in case of head and neck cancer is surgery, followed by chemo- or/and radiotherapy. A potentially effective instrument to improve the outcome of numerous diseases, including viral infections, diabetes and cancer, is RNA interference (RNAi). It has been demonstrated that small interfering RNA and microRNA molecules are strongly involved in the regulation of various different pathological processes in cancer development...

: In this study, high-risk HPV (hrHPV) incidence, prognostic biomarkers, and outcome were assessed in HIV-positive (case) and HIV-negative (control) patients with head and neck squamous cell cancer (HNSCC). HIV-positive cases were matched to controls by tumor site, sex, and age at cancer diagnosis. A tissue microarray (TMA) was constructed and DNA isolated from tumor tissue. MultiPlex-PCR MassArray, L1-PCR and In Situ Hybridization were used to assess hrHPV. TMA sections were stained for p16ink4a, TP53, RB, CCND1, EGFR, and scored for intensity and proportion of positive tumor cells...

BACKGROUND: Tanzania, like other low-income countries, has an increasing cancer burden that remains underestimated. Infection-associated malignancies, particularly HIV-infection, represent a great proportion of cancer burden in Tanzania and throughout Africa. Availability of HIV treatment and improved survival of HIV patients are suggested factors related to increasing prevalence of non-AIDS-defining cancers (NADCs). This study examined patterns of NADCs and proportions of HIV-positivity at the Ocean Road Cancer Institute (ORCI)...

Importance: Initially discovered in 1947, Zika virus infection received little notoriety as a tropical disease until 2015 when an outbreak of microcephaly cases was reported in Brazil. Zika is a single-stranded RNA arbovirus of the Flaviviridae family. The primary source of infection in humans stems from Aedes aegypti mosquito bites but can also occur through sexual, blood, and perinatal transmission. With expectations that 3 to 4 million people across the Americas will be infected over the next year, the World Health Organization has declared this event a Public Health Emergency of International Concern...

INTRODUCTION: Locally advanced unresectable squamous cell carcinoma of head and neck has poor locoregional control when treated with conventionally fractionated Radiation Therapy (RT) alone. However, Concurrent Chemo-Radiotherapy (CRT) and altered fractionated RT schedules like Accelerated Hyperfractionation (AHF) are two different treatment strategies that have shown to be associated with better efficacy as compared to conventional RT alone in such cases. AIM: Aim of the study was to compare these two treatment strategies i...

Head and neck squamous cell carcinoma (HNSCC) is one of the most common solid cancers worldwide. It is mainly caused by exposure to tobacco smoke and alcohol as well as infection with the human papilloma virus (HPV). The prognosis is poor, especially once it recurs or metastasizes. Current therapeutic options include surgery, radio- and chemotherapy. Epidermal growth factor receptor (EGFR) inhibitors are so far the only targeted agents that have been approved in head and neck cancer. Primary or secondary resistance is frequent or will eventually develop...

Mucormycosis is a rare fungal infection with a yearly incidence of 1.7 cases per million in the United States. It often occurs in patients with metabolic abnormalities or immunocompromised patients with prolonged neutropenia but can occur in patients without any underlying disease process. The treatment of choice is surgical debridement of necrotic tissue and systemic antifungal therapy, including amphotericin B. A dilemma for the surgeon when faced with head and neck mucormycosis is the morbidity of surgical debridement from a functional and cosmetic standpoint...

BACKGROUND: The perioperative use of immunomodulatory nutrition formulas in patients with head and neck cancer reduces the number of postoperative infections and the length of hospital stay. OBJECTIVE: An exploratory, randomized, controlled, blind, clinical trial was designed to examine the effect of the preoperative consumption of a new, immunomodulatory, oral nutrition formula in patients with head and neck cancer. METHODS: Thirty-eight patients were randomized to receive either 400 mL/d of either the new immunomodulatory formula (IF) or that commonly used in clinical practice (CF) over 10 days prior to surgery...

Human papilloma virus (HPV)-associated head and neck cancer (HNC) has generated significant amount of research interest in recent times with focus shifted to oral cavity squamous cell cancer (OCSCC) after oropharyngeal cancer. Due to high incidence of OCSCC and anecdotal reports on association of HPV infection from northern region of India, this study was conceived to investigate HPV infection and establish its association with lifestyle habits such as tobacco, alcohol consumption, oro-genital sex, number of sexual contacts, and change in quality of life posttreatment...

S Paul Starr
Nearly 31,000 US patients received solid organ transplants in 2015 and the number is increasing. Care of transplant recipients includes management of a variety of common posttransplantation issues. Skin cancers are common because of immunosuppression and require skin examinations at intervals. Patients should be educated about the need to report new skin lesions. The rates of other cancers also are increased, including cancers of the head and neck, lung, esophagus, cervix, and urinary tract. Osteoporosis is common in transplant recipients; monitoring and early therapy are important...

OBJECTIVES: Head and neck squamous cell carcinomas (HNSCCs) exhibit great biological heterogeneity and relatively poor prognosis. Tobacco and alcohol consumption is involved in the cause of the majority of these cancers, but over the last several years, Human Papilloma Virus (HPV) infection has increased specifically in oropharyngeal cancers and become an additional risk factor. Here, we evaluated the number of Langerhans cells (LCs) in HNSCC and reporting its prognostic power in comparison to other risk factors...

Purpose In squamous cell carcinomas of the head and neck (HNSCC), the increasing incidence of oropharyngeal squamous cell carcinomas (OPSCCs) is attributable to human papillomavirus (HPV) infection. Despite commonly presenting at late stage, HPV-driven OPSCCs are associated with improved prognosis compared with HPV-negative disease. HPV DNA is also detectable in nonoropharyngeal (non-OPSCC), but its pathogenic role and clinical significance are unclear. The objectives of this study were to determine whether HPV plays a causal role in non-OPSCC and to investigate whether HPV confers a survival benefit in these tumors...

The incidence of oropharyngeal squamous cell carcinomas (SCC) is increasing and is believed to reflect changing sexual practices in recent decades. For this case-case comparative study, we collected medical and life-style information and data on sexual behavior from 478 patients treated at the head and neck clinic of a tertiary hospital in Brisbane, Australia. Patients were grouped as (1) oropharyngeal SCC (n=96), (2) oral cavity, larynx and hypopharynx SCC ('other HNSCCs', n=96), (3) other SCCs (n=141), (4) other diagnoses (n=145)...

BACKGROUND: As a consequence of use of metal-on-metal hip arthroplasties some patients have precised revision for pain or metal hipersensivity reactions among other causes. We propose to salvage monoblock acetabular component and femoral component using a dual-mobility head and perform a lower morbidity operation in young patients preserving host bone stock in cases with well fixed and positioned components. OBJECTIVE: (1) What clinical problems have been reported in patients with Metal-on-metal hip arthroplasties? (2) Could the tribocorrosion potentially cause a fracture of neck femoral component? (3) Can be the dual-mobility head a recourse in metal-on-metal hip revision? METHODS: Ten patients were revised for pain or/and raised Cobalt/Chromium levels between August 2012 and December 2015...
