Acute sinusitis: Finnish clinical practice guidelines.

These clinical practice guidelines aim at providing assistance mainly to primary health care physicians for the diagnosis and management of acute sinusitis. Despite the huge impact of upper respiratory infections, criteria for diagnoses are often vague, and physicians are often uncertain of their diagnoses. This is not surprising, as the sole definition of acute sinusitis is somewhat confusing, not to mention the existing discrepancies between treatments, even among specialists.

Sense of smell in long-standing nasal polyposis.

An impaired sense of smell is a common complaint in patients with nasal polyposis, and hyposmia is usually attributed to obstruction of the nasal airways. The duration of nasal polyposis and nasal surgery may also affect olfaction. It has been shown that aging and chronic rhinitis both impair olfaction.

Nasal polyposis: clinical course during 20 years.

Background: The etiology of nasal polyposis is mainly unknown although it has been connected with many clinical conditions. The long-term clinical course of nasal polyposis is largely unknown, because long-term followup studies on the recurrence of nasal polyposis have rarely been reported.

Objective: The aim of the study was to find out the clinical course of nasal polyposis over a long period of time.
