Prediction of outcome by lymph node ratio in patients with parotid gland cancer.

Objective: Lymph node ratio (LNR) has been shown to be an independent predictor of recurrence risk and survival in different entities of carcinoma.

Methods: In this retrospective chart review, 128 patients with parotid gland cancer (PGC) subsequently treated by primary surgery were included. About 64% (n = 82) of these patients were additionally treated with adjuvant radiotherapy.

Feasibility of an interval, inspiration-triggered nocturnal odorant application by a novel device: a patient-blinded, randomised crossover, pilot trial on mood and sleep quality of depressed female inpatients.

It has been suggested that certain odorants positively affect mood, but this has not yet been scientifically tested in humans. The aim of the current study was to demonstrate the feasibility of a new odorant applicator and to assess the effects of nocturnal intermittent rose odorant application on mood, and quality of sleep and dreams in depressed female inpatients. We hypothesised that mood as primary outcome will improve.

Influence of formalin fixation on tissue dimensions in palatal tonsils.

Aim: To investigate the change of tissue dimensions after formalin fixation, and to determine the optimal time of fixation.

Hypothesis: Formalin fixation may lead to shrinkage in tissue dimensions and may thus alter tumor stages.

Background: It is often observed in tumor surgery that the dimensions in vivo seem larger than after resection, and tissue appears to shrink further after formalin fixation.

Occurrence of lymph node metastasis in early-stage parotid gland cancer.

Lymph node metastasis is one of the most important factors in therapy and prognosis for patients with parotid gland cancer. Nevertheless, the extent of the primary tumor resection and the necessity of a neck dissection still is a common issue. Since little is known about lymph node metastasis in early-stage parotid gland cancer, the purpose of the present study was to evaluate the occurrence of lymph node metastases in T1 and T2 carcinomas and its impact on local control and survival.

Impact of recurrent head trauma on olfactory function in boxers: a matched pairs analysis.

Recently, interest in the health of boxers has been raised by a petition of the British Medical Association to restrict boxing. However, scientific data on permanent damage are rare and typical localisations of injuries were yet to be defined. The aim of this study was to determine whether there are changes in the sense of smell in people undergoing recurrent head traumas.
