    Double thyroglossal duct cyst located in the hyoid region and the tongue base: an unusual coexistence.
    (2011) Yorgancilar E.; Yildirim M.; Gün R.; Büyükbayram H.; Topçu I.
    Thyroglossal duct cysts originate from persistent epithelial remnants of the thyroglossal duct that are present during the descent of the thyroid gland from the foramen cecum to its final position in the anterior neck. Thyroglossal duct may persist anywhere along the descent from the tongue to the thyroid. Lingually localized thyroglossal duct cysts are congenital lesions of the pharynx, which are very uncommon and may cause morbidity and mortality if not treated expeditiously. Double thyroglossal cysts and the complete failure of the obliterative process of thyroglossal duct are very rare in the literature. In this article, we describe a case of two cysts derived from the same thyroglossal duct, one in the hyoid region and the other in the tongue base. To our knowledge, this coexistence has not been described previously in the literature.

    Effects of manganese ethylene-bis-dithiocarbamate (Maneb) on rat nasal respiratory mucosa
    (Acta Medica Mediterranea, 2013) Deveci E.; Yorgancilar E.; Ekinci C.; Koparal M.; Akkus Z.; Yavuz D.
    Maneb (Mn-ethylene(bis)dithiocarbamate is a dithiocarbamate pesticides. It is a fungicide pesticide used in the control of mildew disease on certain crops. In general, dithiocarbamates are considered chemicals of low toxicity for humans. However, the effects of maneb in humans are diverse. It has some effects to humans via absorption through skin and respiratory system. The nasal mucosa is the first part of the airways in contact with the environment and toxic agents. The aim of this study was todetermine the histopathological effects of maneb on nasal mucosa. In experimental group, the maneb was administered with inhalation to 10 male Wistar-Albino rats for five days a week. The control group (n=10) received distilled water with spray at the same time period. The experiment was terminated after three weeks. In each case, sections of the nosewere taken. In experimental group,microscopic examination of nasal respiratory mucosa revealed; Hypertrophy of epithelial cells and goblet cells, increasing of mucus secretion, decreasing in sizes of cilia and flattening of the cells near the basement membrane and apoptotic cells in the degenerated respiratory epithelial cells, detected a mild inflammatory reaction and a vascular dilatation in the connective tissue. All changes were statistically significant. In control group of 10 rats no significant histopathologic lesions were found. As a result, our study , maneb is potentially toxic agent to respiratory mucosa.

    Ganglioglioma in the nasal cavity: a case report.
    (2010) Yorgancilar E.; Yildirim M.; Gün R.; Büyükbayram H.; Meriç F.
    Ganglioglioma is a tumor containing both astrocytic and neuronal components. It may occur any where in the central nervous system and spinal cord but is only encountered rarely. Nasal glial heterotopia (also known as ''nasal glioma''), is a rare developmental abnormality seen in a wide age group. Gangliogliomas may also manifest as a nasal glial heterotopia, and neurogenic tumors should be considered in the presence of a nasal mass. In this article, we present a case of ganglioglioma located in the right-nasal cavity. The mass was excised totally through an endoscopic approach. The ganglioglioma developed on a nasal glial heterotopia base. To our knowledge, a ganglioglioma arising from the nasal cavity has not been described previously in the literature.
