Evidence for a causal association for HPV in head and neck cancers

Schwarze HP, Winder D, Steinstraesser L, Görner M, Stanley M, Goon PK; European Archives of Oto-Rhino-Laryngology (Jul 2011)


Current data have now attributed a viral etiology and causality of Human papillomavirus (HPV). Epidemiological analysis of the last decade demonstrates a rapid increase of HPV-associated HNSCC.

AIDS-related primary Kaposi sarcoma of the nasopharynx

Celenk F, Yilmaz M, Asal K, Ekinci O, Tokgöz N; Ear, Nose, & Throat Journal 90 (6), E1-4 (Jun 2011)
Primary nasopharyngeal Kaposi sarcoma is extremely rare, as only 1 case has been previously reported in the literature. We report a new case, which occurred in a 37-year-old man with a known history of acquired immune deficiency syndrome (AIDS).

Patients With Temporomandibular Disorders Have Increased Fatigability of the Cervical Extensor Muscles

Armijo-Olivo S, Silvestre RA, Fuentes JP, da Costa BR, Major PW, Warren S, Thie NM, Magee DJ; Clinical Journal of Pain (Jun 2011)
OBJECTIVES: To determine whether patients with myogenous and mixed temporomandibular disorders (TMD) have greater fatigability of the cervical extensor muscles while performing a neck extensor muscle endurance test (NEMET) when compared with healthy controls.

Saliva polymerase-chain-reaction assay for cytomegalovirus screening in newborns

Boppana SB, Ross SA, Shimamura M, Palmer AL, Ahmed A, Michaels MG, Sánchez PJ, Bernstein DI, Tolan RW, Novak Z, Chowdhury N, Britt WJ, Fowler KB, National Institute on Deafness and Other Communication Disorders CHIMES Study; New England Journal of Medicine (NEJM) 364 (22), 2111-8 (Jun 2011)


BACKGROUND Congenital cytomegalovirus (CMV) infection is an important cause of hearing loss, and most infants at risk for CMV-associated hearing loss are not identified early in life because of failure to test for the infection. The standard assay for newborn CMV screening is rapid culture performed on saliva specimens obtained at birth, but this assay cannot be automated. Two alternatives--real-time polymerase-chain-reaction (PCR)-based testing of a liquid-saliva or dried-saliva specimen obtained at birth--have been developed.

Efficacy of neck dissection for locoregional failures versus isolated nodal failures in nasopharyngeal carcinoma

Tsang RK, Chung JC, Ng YW, To VS, Ho AC, Chan JY, Ho WK, Wei WI; Head & Neck (Jun 2011)
BACKGROUND: Neck dissection has been shown to be effective in controlling nodal failures in nasopharyngeal carcinoma. Its efficacy in controlling the disease in patients with synchronous locoregional failure is, however, not documented.

Primary nasopharyngeal tuberculosis mimicking exacerbation of chronic rhinosinusitis

Prstacic R, Jurlina M, Zižic-Mitrecic M, Janjanin S; Journal of Laryngology & Otology 1-3 (Apr 2011)


Objective:Nasopharyngeal tuberculosis is a rare condition, even in endemic tuberculosis areas. We report a case of primary nasopharyngeal tuberculosis from a non-endemic area, which presented with symptoms resembling exacerbation of previously diagnosed chronic rhinosinusitis.
