    ABSTRACT: To evaluate the results of endoscopic transnasal dacryocystorhinostomy (ETDCR) combined with bicanalicular silicone tube intubation (BSTI) performed in 49 patients with nasolacrimal canal obstructions secondary to chronic dacryocystitis. ETDCR combined with BSTI was applied as a primary procedure in 47 cases, and as a secondary procedure in 2 cases. All patients underwent dacryocystography, and 41 patients underwent radionuclide dacryoscintigraphy before the surgery. Silicone tubes were left in place for about 6.2 months. The patency of the lacrimal passages was controlled with a clinical examination, nasolacrimal canal lavage, and dacryoscintigraphy. Patients were followed up for a mean period of 25.1 months after the removal of the tubes. The epiphora symptom disappeared and a successful drainage could be maintained in 43 out of 49 cases (87.7%). The obstruction rate found in the dacryoscintigraphy performed 15 days after extubation was 22.9%, while it was found to be 14.2% in the nasolacrimal canal lavage. ETDCR combined with BSTI proved to be an effective surgical method in chronic dacryocystitis. The sensitivity and specificity of the postoperative dacryoscintigraphy in determining the surgical success were lower than those of the nasolacrimal canal lavage.

    ABSTRACT: Remittent isolated palsy of peripheral or of upper cranial nerves in diabetic patients is well documented, but paralysis of a lower cranial nerve or an isolated branch of any cranial nerve has rarely been reported. In the case described, besides temporary hypoglossal and facial nerve palsies previously, unilateral temporary vocal cord palsy caused by right inferior laryngeal nerve (recurrent) paralysis associated with type 1 diabetes mellitus is presented. Hoarseness and vocal cord palsy of the patient, as in the case of her first admission with other complaints due to other cranial nerve palsies, totally remitted, presumably both owing to improved metabolic control.

    ABSTRACT: Cadmium, which has adverse effects on many physiological systems, is an important environmental pollutant. Our previous experimental study showed that cadmium also has a dose-dependent deleterious effect on the auditory system in rats. Because zinc reverses cadmium cytotoxicity in many systems, we investigated the possible preventive effect of a zinc-enriched diet given isochronally on cadmium-induced hearing loss in rats. Fifty-four male rats were divided into three equal groups. Control rats were fed normal rat food and tap water, whereas the cadmium group was subjected to 15 ppm cadmium-containing water as CdCl2. The third group received 15 ppm CdCl2 and food enriched with 200 ppm zinc as ZnSO4 for 30 d. On d 30, eight animals from each group were used for the measurement of kidney functions. In the remaining animals, hearing functions were measured by auditory brainstem response and distortion product otoacoustic emission. Blood cadmium increased from 1.87+/-1.69 to 6.08+/-2.62 microg/dL and elevated cadmium contents of ear ossicles and kidney cortex were associated with a decreased glomerular filtration rate in rats subjected to high cadmium. A zinc-enriched diet obviously reduced cadmium accumulation in the kidney and prevented the nephrotoxicity. Our data indicated that cadmium-induced ototoxicity seems to be partially zinc preventable and zinc addition to diet without altering cadmium content in ear ossicles may help to prevent cadmium-induced hearing loss.
