A cephalic phase of colonic pressure response to food was sought in five normal subjects (mean age (22.6) years, 22-24), studied on six separate occasions by recording intraluminal pressures in the unprepared sigmoid colon. Gastric acid secretion was measured simultaneously by continuous aspiration through a nasogastric tube. After a 60 minute basal period, one of five 30 minute food related ce...

PURPOSE This exploratory study examined the relationship between performance on the University of Pennsylvania Smell Identification Test (UPSIT) and the Addenbrooke's Cognitive Examination (ACE) to identify a possible association between olfaction and mild cognitive impairment(MCI). DESIGN AND METHODS 54 community-dwelling older (ages 49-91) volunteers were given the UPSIT and ACE. RESULTS ...

We investigated olfactory function and its relation to cardiac 123I-metaiodobenzylguanidine (MIBG) uptake in 15 patients with drug induced parkinsonism (DIP). The mean Cross Cultural Smell Identification (CCSI) score was significantly greater in patients with DIP than in those with Parkinson's disease (PD: 6.9 (1.6) vs 4.4 (2.2); p<0.001); however, the mean CCSI score in patients with DIP was n...

BACKGROUND Detection of olfactory dysfunction is important for fire and food safety. Clinical tests of olfaction have been developed for adults but their use in children has been limited because they were felt to be unreliable in children under six years of age. We therefore administered two olfactory tests to children and compared results across tests. METHODS Two olfactory tests (Sniffin' S...

How the results of this project will benefit society: Abnormalities in the sense of smell have particular clinical relevance for patients with Alzheimer’s disease (AD), in whom deficits of smell identification and discrimination arise early in the course of illness, and often before the emergence of overt cognitive symptoms such as memory loss. Given the early accumulation of Alzheimer’s pathol...

It is known that both smell and taste functions decrease with aging. However, some clinical questions remain, such as the independence of each sensation loss and the correlation between a person’s actual sensory loss and awareness of the loss. In this research, we investigated both the olfactory and taste functions of aged subjects together with their awareness of sensation loss. Effects of ana...

BACKGROUND Harmane (1-methyl-9H-pyrido[3,4-b]indole), a neurotoxin, may be an environmental risk factor for essential tremor (ET). Harmane and related chemicals are toxic to the cerebellum. Whether it is through this mechanism (cerebellar toxicity) that harmane leads to ET is unknown. Impaired olfaction may be a feature of cerebellar disease. OBJECTIVE To determine whether blood harmane conce...

OBJECTIVE To assess the long-term results of the nasal airflow-inducing maneuver in olfaction rehabilitation in patients who had undergone laryngectomy. DESIGN Prospective interventional study. SETTING University hospital. PATIENTS Twenty-four patients who had undergone laryngectomy (21 men and 3 women; mean age, 68 years) who received olfactory rehabilitation with the nasal airflow-induc...

OBJECTIVE In recent years, a growing number of studies have focused on the olfactory abilities of blind individuals as well as their tactile and auditory senses. In this study, we aimed to investigate possible alterations in the sense of smell in early- and late-blind subjects as compared with sighted controls, using a Sniffin' Sticks test battery. STUDY DESIGN Prospective clinical study. S...
