Metrizamide computed tomographic cisternography was used to examine 27 patients (19 males and eight females, 14-59 years old) clinically suspected of having cerebrospinal fluid fistulae with rhinorrhea. Twenty-one fistulae were traumatic and six were spontaneous. Five to 6 ml of metrizamide (or lopamidol, two cases) were injected by lumbar puncture at a concentration of 185-200 mg I/ml for dire...

We herein describe a case of 44-year old female who presented with a chief complaint of gustatory rhinorrhea from childhood, in which gustatory stimuli caused bilateral excessive, watery nasal secretion. No abnormality of taste acuity was observed. This disorder was presumably caused by faulty regenerated parasympathetic nerve fibers reaching the nasal mucosa or possibly, by a congenital condit...

OBJECTIVE The aim of this study was to determine tympanometric values of children who attend Oporto daycare centers and further analyze any relations with host and environmental factors. METHODS Cross sectional study in a randomly selected sample of 117 daycare children up-to 3-years old from Oporto. Tympanometric measures were collected.

RHINITIS IS A GLOBAL PROBLEM AND IS DEFINED AS THE PRESENCE OF AT LEAST ONE OF THE FOLLOWING: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, n...

OBJECTIVES/HYPOTHESIS Several techniques of endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea were prescribed. Defect localization was mandatory for all. STUDY DESIGN Prospective study. METHODS A prospective study was conducted on nonaccidental CSF rhinorrhea. The sensitivity and specificity of image-guided navigation in localizing the defect were studied. The feasibility and reliab...

Cerebrospinal fluid (CSF) rhinorrhea is rarely reported as the first presenting feature of giant invasive macroprolactinomas. Cerebrospinal fluid rhinorrhea is usually reported as a complication of trauma, neurosurgical, and skull-based procedures (such as pituitary surgery or radiations), and less frequently after medical treatment with dopamine agonists (DAs) for macroprolactinomas. This phen...

Intracerebral tension pneumocephalus is a rare disorder. Only five cases of them have been reported since 1985. We report two cases of intracerebral tension pneumocephalus with traumatic rhinorrhea. In the first case, intracerebral tension pneumocephalus was induced by lumbar puncture performed two months after trauma. In the second case, intracerebral tension pneumocephalus was observed on com...
