BACKGROUND Patients with rhinitis often self-medicate with over-the-counter drugs, however this self-treating population has remained largely unstudied. OBJECTIVE To characterize individuals self-medicating persistent rhinitis and to determine the prevalence of and risk factors for intranasal decongestant overuse within this population. METHODS A cross-sectional observational study of indiv...

Intranasal administration is a method of delivering therapeutic agents to the central nervous system (CNS). It is non-invasive and allows large molecules that do not cross the blood-brain barrier access to the CNS. Drugs are directly targeted to the CNS with intranasal delivery, reducing systemic exposure and thus unwanted systemic side effects. Delivery from the nose to the CNS occurs within m...

OBJECTIVE Treatment of severe hypoglycemia with loss of consciousness or seizure outside of the hospital setting is presently limited to intramuscular glucagon requiring reconstitution immediately prior to injection, a process prone to error or omission. A needle-free intranasal glucagon preparation was compared with intramuscular glucagon for treatment of insulin-induced hypoglycemia. RESEAR...

Intranasal teeth are uncommon, with only a few reported cases in the past few decades. The clinical manifestations of an intranasal tooth are quite variable. Unilateral nasal obstruction is a common complaint, but even though nasal symptoms are present, an intranasal tooth can be an incidental finding during routine examination in patients without nasal discomfort. Although the diagnosis is not...

Long-term use of topical nasal steroids (especially older generation steroids) has been shown to elevate intraocular pressure (IOP), but newer intranasal steroids are thought to have a minimal effect on IOP because of their low bioavailability. This study aimed to investigate alterations in IOP with two commonly used intranasal steroids for a 6-month period of time. One-hundred allergic rhiniti...

We have previously described iatrogenic Cushing's syndrome secondary to intranasal steroids. This report further highlights the potential deleterious effects of intranasal steroids. Nine cases (including the original two cases) are reviewed to show the varied clinical manifestations of adrenal suppression caused by intranasal steroids. Four presented with Cushing's syndrome, three with growth f...

1. It was found in forty rhesus monkeys that intracerebral, intraocular, intracutaneous, intraperitoneal, intraspinal, and neural inoculations of poliomyelitis virus produced no lesions in the olfactory bulbs despite the fact that the animals contracted pronounced paralyses. This indicated that the virus could be restricted to certain neuronal systems. 2. Similarly intranasal inoculation of sev...
