Rhinosinusitis without nasal polyps in COPD.

The validity of the united airway disease concept for rhinosinusitis (RS) and chronic obstructive pulmonary disease (COPD) has been questioned because of methodological limitations in previous studies. In this study we investigated the prevalence of RS without nasal polyps (RSsNP) and the severity of sinonasal symptoms in COPD and a corresponding control group. We also evaluated the diagnostic accuracy of these symptoms for RSsNP in COPD.

Psychophysiological and electrophysiological testing of olfactory and gustatory function in patients with multiple sclerosis.

The olfactory (OF) and gustatory function in multiple sclerosis (MS) patients and possible influencing variables of the disease, such as depression or fatigue, were determined. In an open prospective controlled clinical study 30 patients with MS and 30 healthy controls matched for age, sex and smoking-habits were investigated. With Mini Mental State Examination cognitive dysfunction was excluded, with Expanded Disability Status Scale the patient's ability to accomplish the tests was ensured.

Olfactory and gustatory function in patients with multiple sclerosis.

Background: The olfactory function (OF) and gustatory function in patients with multiple sclerosis (MS) can be limited.

Methods: We performed the testing of orthonasal (Threshold Discrimination Identification [TDI] score with Sniffin' Sticks) and retronasal (Taste Powder) OF and gustatory function (Taste Strips; Burghart, Wedel, Germany) in patients diagnosed with MS and healthy controls matching in age, sex, and smoking habits.

Results: Eight of 16 MS patients (50%) displayed hyposmia (TDI score, 28.
