One hundred and sixty-one patients with a supraglottic laryngeal carcinoma and clinically negative neck were studied. All patients had primary surgery and occult cervical node metastases were found in 18% (29/161). Local dissemination of tumour in the epilarynx did not influence the incidence of occult metastases, while the incidence of occult metastases increased with the degree of local spread in the supraglottis excluding the epilarynx. Ipsilateral occult metastases were more common (76%, 22/29), but both bilateral and contralateral spread was also seen (14%, 4/29 and 10%, 3/29, respectively).

Since ligation combined with low-volume sclerotherapy did not reduce the time required for variceal eradication, it can be concluded that the combined therapy is not superior to ligation alone. This mode of endoscopic therapy for the treatment of bleeding esophageal varices is therefore not recommended.

According to the results obtained, the urban population of Belgrade is among populations with a low prevalence of rheumatoid arthritis.

Computerized rhinomanomatry with the practical software programmes is used widely as a research tool to evaluate objectively nasal air flow and resistance parametres, while the increase of its clinical application may be facilitated by further standardization of the method. The aim of the study was to determine the total nasal resistance normal values in healthy adult population using a method of computerized rhinomanometry. A randomized sample of 108 white healthy adults (216 nasal cavities), both sexs with a mean age of 32 (20 -45) years comprised the test group. Nasal patency was measured by active anterior rhinomanometry in non-decongested mucosa ("at rest") during 10 repetitive measurements at inspiratory and expiratory reference pressure of 150 Pa. Nasal resistance was measured and calculated accoding to the recommendations of the Committee on objective assessment of the nasal airway, International Rhinologic Society.
