ABSTRACT Laryngeal carcinoma can metastasize to many locations among which the neck is the most frequent. In this case report, a 53-year-old patient who was diagnosed with laryngeal carcinoma underwent total laryngectomy, total thyroidectomy and right radical neck dissection. Contralateral neck dissection was planned for 3 weeks later. On the third post-operative week, the patient developed VI and VII cranial nerve paralysis. The patient was given palliative chemoradiotherapy. However, 1 year after the primary diagnosis and 3 months after the cavernous sinus metastasis, he died. Despite the fact that the metastasis of the laryngeal carcinoma to the cavernous sinus is very rare, it has a very unfavourable prognosis.

ABSTRACT Fucoxanthin is a major carotenoid found in marine brown algae. This study investigated the impact of fucoxanthin on the growth performance, antioxidant metabolism and meat quality of broilers. Overall, 180 one-day-old male broiler chicks (Ross 308) were assigned to one control group (CONT) and 2 treatment groups (FUCO1 and FUCO2), with six replicates of 10 birds each. The CONT, FUCO1 and FUCO2 birds were fed a basal diet supplemented with 0, 100 and 200 mg/kg of fucoxanthin, respectively. Average body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were similar among the groups. Fucoxanthin increased catalase (CAT) and superoxide dismutase (SOD) activities and glutathione (GSH) levels (p<0.01), and reduced malondialdehyde (MDA) levels (p<0.01) in the liver, breast and drumstick tissues. The effects of fucoxanthin on drumstick yellowness (b*) on day 3 and water activity (aw) on day 5 and breast lightness (L*) on day 3 b* values days 2 and 5 were limited and variable. While fucoxanthin showed antimicrobial effect against Staphylococcus spp. in the breast meat on days 5 and 6 of storage (p<0.05), its effects at different time periods and against other microorganisms varied. In conclusion, fucoxanthin did not affect performance parameters, but had a significant impact on antioxidant metabolism, and showed a limited effect on the microbial quality of meat.

OBJECTIVES: The aim of this study is to determine the prevalence of dentine hypersensitivity (DH) and to examine some associated factors such as the initiating stimuli among adult patients attending the Restorative Clinic of the Kirikkale University Dental Faculty, Turkey. METHODS: Questionnaires for 1169 patients, 678 men and 491 women, were completed and necessary clinical examinations performed during a one-year period and patients who were diagnosed with DH were questioned further about their occupation and smoking habits. Patients with at least two different quadrants which had sensitive teeth with sound exposed cervical dentine on the facial surface, were included in the study. The amount ofcervical lesions, buccal gingival recession and initiating factors associated with the sensitive teeth were also recorded. RESULTS: Of the 1169 patients examined, 89 were diagnosed as having dentine hypersensitivity, giving a prevalence of 7.6%. The commonest teeth affected were the upper premolars and the commonest initiating factor was cold drinks. CONCLUSIONS: The prevalence of dentine hypersensitivity in a postgraduate clinic in Turkey was 7.6%. The commonest teeth affected were the upper premolar and the commonest initiating factor was cold drinks.

OBJETIVOS: El objetivo de este estudio fue determinar la prevalencia de la hipersensibilidad dentinaria (HD) y examinar algunos factores asociados con ella, tales como los estÃmulos iniciadores entre los pacientes adultos que asisten a la ClÃnica Restaurativa la Facultad Dental Universitaria de Kirikkale, TurquÃa. MÉTODOS: Cuestionarios entregados a 1169 pacientes, 678 hombres y 491 mujeres, fueron respondidos, y se realizaron los exámenes clÃnicos necesarios por espacio de un ano. Los pacientes que fueron diagnosticados con HD, fueron interrogados ulteriormente acerca de su ocupación y el hábito defumar. Los pacientes con al menos dos cuadrantes diferentes, que tenÃan dientes sensibles con exposición de dentina cervical sana sobre la superficie facial, fueron incluidos en este estudio. También se registró la cantidad de lesiones cervicales, la recesión gingival bucal y los factores iniciadores asociados con la sensibilidad de los dientes. RESULTADOS: De los 1169 pacientes examinados, 89 se diagnosticaron con hipersensibilidad de la dentina, para una cifra de prevalencia de 7.6%. Los dientes más comúnmente afectados fueron los premolares superiores y los factores iniciadores más comunes fueron las bebidas frÃas. CONCLUSIONES: La prevalencia de la hipersensibilidad dentinaria en una clÃnica postgraduada en TurquÃa fue de 7.6%. Los dientes más comúnmente afectados fueron los premolares superiores y el facgor iniciador más común fueron las bebidas frÃas.
