OBJECTIVE: To apply the Bradford Hill criteria, which are widely used to establish causality between an environmental agent and disease, to evaluate the relationship between over-the-counter intranasal zinc gluconate therapy and anosmia. DESIGN: Patient and literature review applying the Bradford Hill criteria on causation. SETTING: University of California, San Diego, Nasal Dysfunction Clinic.

OBJECTIVE: The pathogenesis of idiopathic hypogonadotrophic hypogonadism (IHH) is mostly unclear. We characterized the clinical findings and molecular analysis of GnRHR and KAL1 genes in 26 Brazilian males with IHH with and without hyposmia/anosmia. Design Clinical assessment was performed for endocrine status, olfactory structure and function, renal lesion, and mirror movement. The diagnosis of Kallmann syndrome (KS) included HH and the clinical complaint of hyposmia/anosmia or decreased olfactory acuity obtained by the Smell Identification Test (SIT).

OBJECTIVES: Two controlled trials of aromatherapy to decrease agitation in persons with dementia have recently produced promising results. However, both studies combined the use of essential oils with massage. Thus, it is unclear if the effect of the aromatherapy intervention was the result of smelling or the cutaneous absorption of the oils. The purpose of this study was to determine whether smelling lavender oil decreases the frequency of agitated behaviors in patients with dementia.

There has been an increase in the use of psychophysiological techniques, especially event-related potentials (ERPs) to evaluate the effects of odor on the central nervous system. In the study of ERPs related to odor, there are two main methods of the odor presentation: (1) to investigate the olfactory ERP (OERP) or chemosensory ERP (CSERP), that is to calculate electrophysiological responses to odor stimulation as a trigger; (2) to compare ERP of mental functioning during the odor exposed condition with that of no odor exposure.

Systemic lupus erythematosus (SLE) is an autoimmune disease associated with more than 100 different autoantibodies, some of which may be associated with specific neuropsychiatric (NPSLE) manifestations. Injection of anti-P ribosomal antibodies (anti-P) directly to the brain ventricles of mice induces depression manifested by increased immobility time in the forced swim test (FST). METHODS: Mice were injected intracerebroventricularily (ICV) with affinity-purified human anti-P antibodies or normal commercial IgG as control.

This is a report detailing the successful treatment of a case of anosmia with acupuncture. The patient was managed conventionally for two years with no sign of improvement. She regained the sense of smell following one session of acupuncture. Such patients should be investigated for any detectable organic cause prior to treatment with acupuncture.
