BACKGROUND The etiology of sudden sensorineural hearing loss (SSNHL) is still unclear and is most probably diverse. OBJECTIVE To determine the relationship between vertebrobasilar circulation and hearing in patients with SSNHL treated with pentoxifylline. DESIGN Case-control study of 32 consecutive patients with SSNHL. METHODS Patients with onset of(More)
Acid base balance changes were observed during 72 h following bilateral nasal obstruction in rats. Mouth breathing caused acute respiratory acidosis and marked aerophagia, leading to spontaneous death of the experimental animal 80 to 90 h postoperatively. Stenotic oropharyngeal airway, due to palatal-epiglottic approximation, is supposed to be responsible(More)
The most common etiologic cause of thyrotoxicosis in children and adults is autoimmune Graves' (Basedow's) disease. Antithyroid medications, surgery and radioactive iodine have been used in the treatment of Graves' hyperthyroidism for more than six decades. The use of antithyroid drugs is the most common therapeutic approach. However, long-term remission(More)
The effect of suppressive treatment with thyroid hormones on thyroidal iodothyronines and T4/T3 ratio in nodular and paranodular tissues was investigated in 12 patients with nontoxic goiter. Results were compared to those from 11 nontreated patients. Continuous thyroid hormone administration produced a significant increase in thyroidal T4 and T4/T3 ratio in(More)
The relationship between T4, T3 and T4/T3 ratio in thyroid nodules/paranodular tissues, thyroid and peripheral veins has been investigated in 26 patients with nontoxic nodular goiters; eleven of them were treated with l-thyroxine 150 micrograms daily. A significant correlation between iodothyronine concentrations and T4/T3 [corrected] ratio in paranodular(More)
AIM To determine diagnostic relevance of cytologic subclassification of follicular lesions of the thyroid and its role in the therapeutic approach. METHODS We performed a retrospective analysis of the data of patients who underwent thyroid surgery at the Sisters of Mercy University Hospital, Zagreb, between March 1995 and February 2001, and had a report(More)
Thyroidal thyroxine (T4), triiodothyronine (T3), thyroglobulin (Tg) and T4/T3 ratio were investigated in nodular and paranodular tissue from 16 patients with autonomously functioning thyroid adenomas. The concentration of T4 and T3 in the nodule were 97.7 +/- 20.5 (Mean +/- SE) and 10.2 +/- 2.4 micrograms/g wet weight (w.w.). Both iodothyronines were(More)
Thyroidal concentrations of T4 and T3 and the T4/T3 ratio were analyzed in the nodular and paranodular tissues from two groups of patients with suppressed TSH secretion. The first group consisted of 17 patients with nontoxic nodular goitre (NG), 8 of whom received long-term levothyroxine therapy to suppress TSH, while remaining 9 were untreated. The second(More)
We report the changes in blood gas tensions in a group of 17 patients during a five-day period of anterior nasal packing after endonasal surgery. Significant hypocapnia was observed in the early postoperative period, which was followed by significant hypoxemia within the first 48 h after surgery, and also shortly after removal of the nasal pack. Analyses of(More)
