Background: Inflammatory processes play a central role in the pathogenesis of chronic rhinosinusitis (CRS), however, the impact of apoptosis in CRS in unclear. The aim of this study was a comparison of caspase 3 activity, a key enzyme in the apoptosis cascade, in samples of nasal tissue from patients with different types of rhinosinusitis.

Material And Methods: Immunohistochemical analyses were carried out to detect caspase 3 in samples of nasal tissue from patients with CRS and nasal polyps (NP), allergic rhinitis (AR), rhinitis medicamentosa (RM) and atrophic rhinitis.

Many patients have nasal syndromes that are nonallergic and noninfectious and not caused by mechanical or anatomic abnormalities. There are at least 8 recognized nonallergic rhinitis syndromes: drug-induced rhinitis including rhinitis medicamentosa, gustatory rhinitis, hormonally induced rhinitis including the rhinitis of pregnancy, nonallergic rhinitis with eosinophilia syndrome, senile rhinitis, atrophic rhinitis, cerebral spinal fluid leak, and vasomotor rhinitis. Few studies have explored etiologic causes.

Rhinitis medicamentosa (RM) is a drug induced non-allergic rhinitis associated with prolonged use of topical nasal decongestants. This review discusses the nasal mucosa microcirculation, basic pharmacology of topical decongestants and the theories of the pathophysiology of RM. Diagnostic problems are discussed in addition to the current opinion on how to treat RM.

Background: The purpose of this study was to evaluate long-term outcomes of an outpatient-based diode laser inferior turbinate reduction (ITR) in therapy-refractory rhinitis medicamentosa (RM).

Methods: In a prospective clinical investigation, 42 consecutive RM patients underwent videoendoscopic ITR with a diode laser after topical anesthetic preparation. Intra- and perioperative details were recorded including the occurrence of bleeding, crusting, pain, or discomfort.

Rhinitis of allergic and viral origin is often self-treated by patients with locally applied vasoconstrictor decongestant drugs. In turn, prolonged use of these agents produce an inflammatory condition termed rhinitis medicamentosa. Cationic drugs are sequestered into cells via various mechanisms, including mitochondrial concentration and V-ATPase-driven trapping in vacuoles that swell by an osmotic mechanism.

Objective: Prolonged application of nasal vasoconstrictors causes rhinitis medicamentosa (RM). Nasal obstruction is induced by rebound swelling when the decongestive effect has disappeared. The aim of this study was to demonstrate ultrastructural changes in RM.

Rhinitis medicamentosa (RM) is a condition induced by overuse of nasal decongestants. The term RM, also called rebound or chemical rhinitis, is also used to describe the adverse nasal congestion that develops after using medications other than topical decongestants. Such medications include oral beta-adrenoceptor antagonists, antipsychotics, oral contraceptives, and antihypertensives.

University of Florida College of Medicine, Department of Community Health and Family Medicine, 32601, USA.

Allergic rhinitis, the most common type of rhinitis, generally can be differentiated from the numerous types of nonallergic rhinitis through a thorough history and physical examination. Allergic rhinitis may be seasonal, perennial, or occupational. The most common cause of nonallergic rhinitis is acute viral infection.

Background: Long-term abuse of decongestive nasal drops causes rhinitis medicamentosa due to cytotoxic and ciliary-toxic effects. Nasal obstruction is caused by rebound swelling when the decongestive effect has disappeared. The patient starts using nasal drops more frequently as a result of tachyphylaxis.

Objective: To review the literature on postnasal drip syndrome (PNDS)-induced cough and the various causes of PNDS. Hereafter, PNDS will be referred to as upper airway cough syndrome (UACS).

Methods: MEDLINE search (through May 2004) for studies published in the English language since 1980 on human subjects using the medical subject heading terms "cough," "causes of cough," "etiology of cough," "postnasal drip," "allergic rhinitis," "vasomotor rhinitis," and "chronic sinusitis.

Thirty-six persistent allergic rhinitis (PAR) sufferers were studied, to both compare and correlate 15 minute response to nasal xylometazoline (XYLO) with 28 day response to nasal mometasone furoate (MF). 0.1% XYLO (1 spray each nostril) response was measured on two occasions, then a randomised double blind cross-over comparison of MF (200 mcg daily) to placebo conducted.

Long term use of topical vasoconstrictors for the nose may result in rhinitis medicamentosa, the rebound swelling of the nasal mucosa. Usually discovery of any underlying reason for decongestant use is impossible, therefore treatment could be problematic. The aim of this study was to establish the nasal mucosal cytology of patients with rhinitis medicamentosa and evaluation of usefulness of exfoliative cytology in diagnostics of underlying reason of nasal decongestants overuse.

Pregnancy rhinitis is a common condition that is not yet fully recognized by the public. This form of rhinitis affects approximately one in five pregnant women, can start in almost any gestational week, and disappears after delivery. However, as it reduces quality of life, and also possibly affects the fetus, treatment is often required.

To evaluate the nasal mucosal changes in rhinitis medicamentosa (RM), especially those related to goblet cells and subepithelial glands, we studied specimens of the inferior turbinate mucosa from 8 patients with RM, 8 patients with chronic hypertrophic rhinitis (CHR), and 5 patients with normal nasal mucosa. All specimens were assessed by electron microscopy and immunohistochemical study. Under a scanning electron microscope, hyperplasia of goblet cells was most prominent in the RM group, and an increased number of gland openings was evident in the RM and CHR groups.
