We describe five patients with cervical spondylosis and large anterior osteophytes causing pharyngeal compression. All had dysphagia, two had obstructive sleep apnoea and another two had dyspnoea and stridor on inspiration. One, with perforation of the pharynx, required emergency tracheostomy. Only three had pain in the neck or arm. Compression of the(More)
CONCLUSIONS We identified smoking as a significant risk factor for multilocular Warthin tumor development. Therefore, we recommend taking history of smoking into account when making the decisions for surgical strategy. OBJECTIVES Warthin tumor is a common benign neoplasm of the parotid gland. Risk factors for multilocular development have not been(More)
Die Kernspinsialographie wird als Modifikation einer MR-Pulsfolge vorgestellt und ihre Speichelgangdarstellung mit der digitalen Subtraktionssialographie als Standard verglichen. Bei 10 gesunden Probanden und 15 symptomatischen Patienten mit Erkrankungen der Glandula parotis wurde eine stark T2-gewichtete Kernspintomographie (TR 3600, TE 800) angefertigt,(More)
OBJECTIVE To analyze the incidence and risk factors for clinically apparent and occult lymph node metastases in patients with major salivary gland cancers. DESIGN Cohort of patients with a median follow-up of 46 months (range, 1-174 months). SETTING University-based referral center. PATIENTS A total of 160 consecutive patients with complete clinical(More)
Open partial laryngectomies include a broad variety of vertical or horizontal partial or supracricoid laryngectomies. Especially in Germany the excellent results of the transoral approach in combination with the CO2 laser surgery radically have diminished the indications of the open surgical techniques for laryngeal cancer staged cT1-2. In patients with(More)
A prospective multicenter phase-II trial (12 centers) was performed by the German larynx organ preservation group (DeLOS) to evaluate the effect of induction chemotherapy (ICHT) with paclitaxel/cisplatin (TP), followed by accelerated-hyperfractionated (concomitant boost) radiotherapy (RT) in responders. The trial was focused on larynx preservation, tumor(More)
Dipeptidyl carboxypeptidase is a C-terminal exopeptidase of Escherichia coli. We have isolated the respective gene, dcp, from a low-copy-number plasmid library by its ability to complement a dcp mutation preventing the utilization of the unique substrate N-benzoyl-L-glycyl-L-histidyl-L-leucine. Sequence analysis of a 2.9-kb DNA fragment revealed an open(More)
PURPOSE To prove an expected benefit of concurrent radiochemotherapy (RCT), a two-arm randomized multicentric study was performed. In a subgroup analysis the influence of pretherapeutical hemoglobin level (p-Hb) on survival under locoregional control (SLC) was tested. PATIENTS AND METHODS The study included primarily untreated Stage III/IV (International(More)
In head and neck squamous cell carcinoma (HNSCC) aerobic glycolysis is the key feature for energy supply of the tumor. Quantitative microdialysis (μD) offers an online method to measure parameters of the carbohydrate metabolism in vivo. The aim was to standardize a quantitative μD-study in patients with HNSCC and to prove if a ketogenic diet would(More)
AIM To investigate the effect of Emdogain Gel (Biora AB, Malmo, Sweden), consisting of a enamel matrix derivative (EMD) in a propylene glycol alginate (PGA) vehicle, on experimentally exposed human pulps and to register postoperative symptoms. METHODOLOGY Nine pairs of contralateral premolars scheduled for extraction on orthodontic indications were(More)
