The need for objective assessment of nasal patency in the fields of rhinosurgery and allergy has led to the development of various methods for the evaluation of nasal patency. These methods include active anterior rhinomanometry, PNIF, acoustic rhinometry, rhinostereometry, optical rhinometry, minimal cross-sectional area endoscopy, nasal sound spectral analysis, magnetic resonance imaging and numerical flow simulation. This article provides a brief overview of currently common procedures., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Providing expert opinion in the context of smell disorders is often challenging, not only with regard to general aspects of providing an expert opinion but particularly with regard to chemosensory testing. Currently there is no consensus which chemosensory test should be selected and how they should be executed. This positions paper from Committee on Olfaction and Gustation of the German Society of Otorhinolaryngology, Head and Neck Surgery aims to give concrete recommendations for chemosensory testing for providing expert opinion for smell disorders with regard to the selection and execution of these test., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim: The Nasal Spray Evaluation Questionnaire is a standardized means to evaluate hedonicity of nasal sprays in the English speaking countries. To date, there is no such questionnaire for German speaking patients. The here presented study aimed at evaluating the translated questionnaire. Three nasal sprays were tested and the questionnaire was used to estimate sensory hedonicity. Finally, the questionnaire was improved and can now serve as a standardized means to measure nasal sensory perceptions., Material and Methods: The questionnaire was literally translated from English to German. There were three groups of 60 patients each presenting with the sensation of a 'dry nose' to a secondary medical center with a board certified otolaryngologist. The ingredients of the three different nasal sprays varied only in one phytotherapeutic addition. The first evaluation of the nasal spray was conducted immediately after application of the nasal spray, and two minutes after application. A third and optional telephone survey was performed several days later after continuous use of the spray., Results: The different evaluations of nasal sprays were already lined out after the first questionnaire. It could serve as a new, reliable and reproduceable tool for the evaluation of nasal sensory perceptions., Discussion: The questionnaire served as an adequate tool to estimate hedonicity of nasal sprays. First results of the German version show, however, that it could facilitate the evaluation by restructuring the questionnaire. Continuously marking good grades with high points (maximum 100) and negative answers with low points (minimum 0 points) will unify and simplify the questionnaire., Conclusion: The translation of the Nasal Spray Evaluation Questionnaire into a German version can serve as a new standard tool for measuring nasal sensation., (Georg Thieme Verlag KG Stuttgart * New York.)

A 33-year-old, otherwise healthy female nursing student presented to the ear-, nose-, and throat- (ENT) outpatient clinic with a globus sensation that had been progressing for 6 months. Tomographic imaging revealed a neck mass extending from the 4th vertebrum to the subclavicular region and apex of the left lung. A surgical resection with histopathological examination exposed a neurofibroma. Management and differential diagnoses of globus sensation are herein discussed. This case underlines the importance of tomographic imaging, even in common but persisting symptoms such as globus sensation.

Deep brain stimulation of ventral intermediate nucleus (VIM-DBS) has become an established therapy for severe essential tremor (ET). The technique is however limited in some ET patients by relevant side effects such as paresthesia, dysarthria, and gait disturbances. To our knowledge, this is the first report of VIM-DBS-induced reversible hypogeusia along with retroinsular cortical deactivation under effective VIM stimulation measured with 18-fluorodexoglucose positron emission tomography. This case demonstrates that gustatory dysfunction should be considered in the pre- and postsurgical management of patients with VIM-DBS. Moreover it provides direct evidence that the thalamus acts as an important relay station in the human cerebral gustatory pathway.

Since 1969 all our patients below the age of three years with congenital dislocation of the hip are treated by a modified overhead-traction (Extensionsreposition) and the "Hanausek-Apparat" for retention. Because of good results of careful reduction and retention in a mitigated Lorenz-position we also treated osteomyelitis of the hip-joint in newborns and following dislocation by this method. It is reported of 3 cases, different types of osteomyelitis of the hip and the method are described.

In a comparative study among two groups of patients--persons with a medial fracture of the collum femoris and persons with advanced coxarthrosis--the zinc-content of the femur was measured. For this analysis a bone-biopsy was performed when an endoprothesis was implanted. In some of the patients the zinc-levels in the blood were determined on several occasions. If the zinc-content of the blood was low, similarly the zinc-content of the bone was reduced, especially in patients with medial fractures. In patients with severe coxarthrosis the zinc-content is reduced by 50%.

With the new x-ray medium Metrizamid it is possible to perform almost complication-free lumbar and thoracic myelography. In an experience the type of complications arising were reduced to moderate headaches, mild nausea occasional dissiness. No convulsions were seen. The number of complications are less than with other watersoluble contrast medium.

Tertiary hyperparathyroidism in a 47-year-old woman was accompained by metastatic and "tumour-like" calcifications. The latter were characterized by tumours of different-sized calcium-containing pseudocyts, surrounded by a cell-rich tissue predominantly containing fibroblasts, histocytes and foreign-body giant cells, which in their cytoplasm contained Cossa-positive particles. Pathogenesis and aetiology of the disease are largely unknown.

20 patients undergoing extended hip surgery received a single i.v. injection of 2 g 6-[(R)-2-[3-methylsulfonyl-2-oxo-imidazolidine-1-carboxamido]-2-phenyl-acetamido]-penicillanic acid sodium salt (mezlocillin, Baypen). At different times after the infections but simultaneously 31 samples of blood and bone (spongiosa) were collected for determination of mezlocillin concentrations. On an average, maximum concentrations of approximately 20 microgram/g bone were demonstrated 30 min after injection, these being within the clinico-therapeutical range. The concentration of azlocillin--another acylureido-penicillin--was comparatively higher.

In a prospective, randomised study 35 patients suffering from lumbar vertebral disc herniation were given an intrathecal and peridural injection of 0.5 ml (= 10 mg) Triamcinolone hexacetonide. The postoperative course of the disorder was compared with that of 35 patients operated on the same manner, however, without medication. It was established that the intraoperative administration of Triamcinolonhexacetonid had no statistically significant influence on the results of the operations.

From 1. 1. 1971--30. 6. 1977 (6.5 years) 4,169 aseptic orthopaedic operations were performed in the Orthopädische Universitätsklinik Düsseldorf. 42 complications of wound healing have been observed (1%)9 Without an ultrasteril operationbox it is also possible to reduce the complications of wound healing in orthopaedic surgery. It is important to know the principles of asepsis and antisepsis, the method of our preoperative preparation of patients is described; the indication of prophylaxis of chemotherapeutic agents should be severe.
