In order to investigate the fluid dynamic preconditions that guarantee a sufficient contact of air with nasal mucosa, we studied flow patterns in modified "Mink's boxes" and in nasal models. As a result, the nose can be divided into 1) a functional area, i.e. area of turbinates, 2) an inflow area, i.e. vestibulum, isthmus and anterior cavum and 3) an(More)
The largest diameter and area of the head of the caudate nucleus in the CT slice closest to the foramina of Monro were compared to other conventional parameters used in confirming Huntington's disease and contrasted with two groups of non-Huntington patients. A maximum diameter under 6.5 mm and an area under 92.5 mm2 were indicative of, but not specific(More)
Sixteen healthy, normotensive husband-wife pairs participated in a study to investigate the effect of reduction of dietary sodium intake (goal less than or equal to 60 mEq/day) on blood pressure. Sodium excretion decreased from a control average of 152.7 +/- 10.1 (SE) mEq/day to 69.5 +/- 4.5 mEq/day (p less than 0.001). Results indicated significant(More)
BACKGROUND Especially to young examiners, the interpretation of rhinometric findings seems to be difficult. In order to understand rhinometric assessments precisely, knowledge of airflow behavior in the nose is necessary. We therefore investigated the influence of nasal concha surgery on acoustic rhinometry and rhinoresistometry in a model. METHOD Six(More)
BACKGROUND Constipation is an occasional problem after gastric banding and is often caused by insufficient liquid intake. As a result, the use of laxatives is widespread in such patients. Depending on the laxative, improper use can lead to bolus obstruction above the band, as occurred in this case. CASE REPORT A 59-year-old female with uncomplicated(More)
To test the utility of a qualitative chloride titrator strip in facilitating compliance with a reduced sodium intake diet, we enrolled 32 patients into a randomized crossover trial comprising two study periods of four weeks each. The study periods were begun after the patients had undergone extensive instruction in the diet and the use of the strip. A high(More)
Palinoptic, visual perseverative, or prolonged positive after-image phenomena have most often been met in right-sided occipital pathology. Less frequent with left-sided lesions they can be associated with the alexia without agraphia syndrome (with or without color naming deficit or hemifield loss). This is illustrated by our case in which rapidly fading(More)
BACKGROUND The nasal septal deviation is a common cause of nasal obstruction. On the other hand, many septal deviations are asymptomatic. It seems a physiological adaptation occurs on both sides. Septal deviation leads to internal nasal asymmetry, which in turn causes compensatory change in turbinate morphology (e.g. turbinate hypertrophy respectively(More)
BACKGROUND Septal perforation is a common clinical problem in rhinology. Affected patients suffer from a dry nose, crusts as well as recurrent epistaxis and sometimes an inspiratory whistle. The aim of this study was to investigate the underlying flow dynamic mechanisms. METHODS The physical flow effects of such pathologies were examined in functional(More)
