While the influences of such variables as age and sex are well established for most standardized tests of odor identification and detection, this is not the case for tests of odor memory. In this study, 231 non-smoking men and women, ranging in age from 10 to 68 years, were administered a standardized 12-item match-to-sample microencapsulated odor memory test (OMT). Anosmics were excluded from ...

Background The return of olfaction and of sinonasal function are important end points after pituitary surgery. Opinions differ on the impact of surgery because techniques vary greatly. A modified preservation of the so-called olfactory strip is described that utilizes a small nasoseptal flap and wide exposure. Methods A cohort of patients undergoing pituitary surgery and endoscopic sinonasal tu...

BACKGROUND Endoscopic skull base surgery is now the preferred treatment option to remove skull base tumors. OBJECTIVE To evaluate the patient's sense of smell and mucociliary clearance time (MCT) after skull base surgery. METHODS Patients with pituitary adenoma underwent a transnasal transsphenoidal endoscopic approach (TTEA group, n = 36), whereas patients with other benign parasellar tumo...

OBJECTIVES To present methods and baseline results for an online screening tool to identify increased risk for Parkinson's disease (PD) in the UK population. METHODS Risk estimates for future PD were derived from the results of a systematic review of risk factors and early features of PD. Participants aged 60-80 years without PD were recruited by self-referral. They completed an online survey...

OBJECTIVE To characterize the olfactory identification in 40 essential tremor (ET) patients, with the University of Pennsylvania 12 Smell Identification Test (UPSIT), to correlate UPSIT scores to clinical and epidemiological data and to compare it to 89 aged matched controls. METHOD Patients were assessed using ET Clinical Scale of Evaluation and UPSIT. RESULTS In patients with ET, the UPSI...

Olfactory decline represents one of the earliest signs of Alzheimer’s disease (AD), and deficits in olfactory identification have now been identified in persons with amnestic mild cognitive impairment (aMCI). Whether the olfactory identification deficit in AD reflects underlying degraded semantic knowledge or lower-order olfactory deficits is uncertain. To address this question, we focused on t...

AIM To evaluate Lancefield grouping and caramel smell for presumptive identification of the Streptococcus milleri group, and to find whether Lancefield group, species, or protein profile correlated with virulence or infection site. METHODS Prospective studies were made of 100 consecutive streptococcal isolates in blood cultures or pus from 100 patients in whom the severity of infection was ca...
