Intraoral Ultrasound versus MRI for Depth of Invasion Measurement in Oral Tongue Squamous Cell Carcinoma: A Prospective Diagnostic Accuracy Study.

Oral squamous cell carcinoma (OSCC) of the tongue is the most common type of oral cavity cancer, and tumor depth of invasion (DOI) is an important prognostic factor. In this study, we investigated the accuracy of intraoral ultrasound and magnetic resonance imaging (MRI) for assessing DOI in patients with OSCC. Histopathological measurement of DOI was used as a reference standard.

Danish translation of the Neck Dissection Impairment Index.

Background: Shoulder pain and impairment are known complications to neck dissections (NDs) as part of the surgical management of head and neck cancer (HNC). The Neck Dissection Impairment Index (NDII) is a validated shoulder function-related quality-of-life instrument and an important patient reported outcome measure after head-neck surgery. The correct translation of questionnaires into other languages is important for both individual assessment of patients and future research.

Mucosal biofilm detection in chronic otitis media: a study of middle ear biopsies from Greenlandic patients.

The objectives of this study were to examine middle ear biopsies from Greenlandic patients with chronic otitis media (COM) for the presence of mucosal biofilms and the bacteria within the biofilms. Thirty-five middle ear biopsies were obtained from 32 Greenlandic COM patients admitted to ear surgery. All biopsies were examined by means of peptide nucleic acid-fluorescent in situ hybridization (PNA-FISH), and if possible culture and polymerase chain reaction (PCR) of the 16s rDNA and sequencing.

Morphological evidence of biofilm formation in Greenlanders with chronic suppurative otitis media.

Biofilm may explain the recurrences and recalcitrant episodes of otorrhea in chronic suppurative otitis media (CSOM). This study investigates bacterial biofilm in Greenlanders with CSOM and chronic otitis media with effusion (COME). The study is partly blinded, prospective and retrospective.
