[Nasal resistance and continuous positive airway pressure treatment for sleep apnea/hypopnea syndrome].

OBJECTIVE: To evaluate the relation between nasal resistance and tolerance and compliance with continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea/hypopnea syndrome (SAHS). MATERIAL AND METHOD: One hundred twenty-five patients with a mean apnea/hypopnea index (AHI) of 53 21 were assessed for nasal resistance by active anterior rhinometry before starting CPAP treatment. Airflow (cm3/s) at 150 Pa was measured at each nostril. Tolerance for and compliance with CPAP was assessed at 2 weeks, 6 months and one year after start of treatment. RESULTS: The mean CPAP prescribed was 9 2 cmH2O. Rhinometry findings were considered pathological for 70 patients (56%). We observed no correlation between nasal flow and the CPAP established (r = 0.018). The treatment compliance objective in the first year was 5 1.5 hours/day. The most common nasal side effects during this period were runny nose, itching and sneezing (24%), oronasal dryness (21%) and subjective nasal obstruction (6%). There were no significant differences in tolerance of or compliance with CPAP treatment between patients with normal or abnormal rhinometry. CONCLUSIONS: Nasal resistance assessed by anterior rhinometry is unrelated to optimum CPAP and does not affect either tolerance or compliance among patients with SAHS.

[2 cases of adenocarcinoma of nasal cavities and paranasal sinuses].

Malignant tumors of the paranasal sinuses are relatively rare. Generally squamous cell carcinoma appear to be dominant. Adenocarcinoma make up 12 to 15 percent of all nasal and paranasal sinus malignancies. Adenocarcinomas are most often seen in the middle turbinate and ethmoid sinus. We report 2 cases and discuss its clinical findings, the treatment and possible etiologies.

[Reconstructive septal surgery: review of various implants in the nasal area].

In the reconstructive techniques of the nose the rhinologist must employ several materials for rebuilding unprotected septo-pyramidal areas. In spite of its partial resorption the cartilage continues to be the best element. Other objections for its use either the distortion or its weakness against infections, are overcome by an appropriate preparation of the graft.

[Vasomotor rhinitis. Clinical study: an attempt at classification].

In the AA's opinion the greatest number of rhinitis cases seen in the doctor's office are vasomotor rhinitis. The vasomotor response being determined because of the hyper-reactivity of the subject in face of several agents. After explanations of the fundamentals of their theory a perusal of the more frequent etiologies and differential symptoms are listed. The paper ends with a summary of the medications available, their pharmacologic activity and their respective indications.

[Assessment of the prognostic capacity improvement of the 5th edition of the TNM in patients with nasopharyngeal carcinoma].

OBJECTIVE: Evaluate the changes included in the 5th edition of the TNM classification in patients with nasopharyngeal carcinoma. PATIENTS AND METHODS: Retrospective study of 103 patients with nasopharyngeal carcinoma treated with radical intention in our centre from 1985 to 1997. A reclassification according to the criteria defined in the 5th edition of the TNM was carried out. The loco-regional control and survival obtained when patients were classified with the 4th and 5th editions of the TNM were compared. RESULTS: The use of the 5th edition of the TNM led to a decrease in local category (T) and stage grouping, improving the prognostic capacity in local control and survival. The changes included in the 5th edition of the TNM did not modify the regional classification in a essential way. CONCLUSIONS: The changes included in the 5th edition of the TNM improved the classification of patients with nasopharyngeal carcinoma.
