    Beta-Hydroxy-Beta-Methyl-Butyrate, L-glutamine, and L-arginine Supplementation Improves Radiation-Induce Acute Intestinal Toxicity
    (Taylor & Francis Ltd, 2019) Yavas, Cagdas; Yavas, Guler; Celik, Esin; Buyukyoruk, Ahmet; Buyukyoruk, Cennet; Yuce, Deniz; Ata, Ozlem
    We aimed to evaluate effects of beta-hydroxy-beta-methylbutyrate, L-glutamine, and L-arginine (HMB/GLN/ARG) on radiation-induced acute intestinal toxicity. Forty rats were divided into four groups: group (G) 1 was defined as control group, and G2 was radiation therapy (RT) control group. G3 and G4 were HMB/GLN/ARG control and RT plus HMB/GLN/ARG groups, respectively. HMB/GLN/ARG started from day of RT and continued until the animals were sacrificed 10 days after RT. The extent of surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis, crypt distortion, regenerative atypia, vascular dilatation and congestion, and fibrosis were quantified on histological sections of intestinal mucosa. Statistical analyses were performed using the analysis of variance (ANOVA) test. There were significant differences between study groups regarding extent of surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis and crypt distortion, regenerative atypia, vascular dilatation and congestion, and fibrosis (p values were 0.019 for fibrosis, <.001 for the others). Pair-wise comparisons revealed significant differences regarding surface epithelium smoothing, villous atrophy, lamina propria inflammation, cryptitis, vascular dilatation, and congestion between G2 and G4 (p values were <.001, .033, <.001, .007, and <.001, respectively). Fibrosis score was significantly different only between G1 and G2 (p = .015). Immunohistochemical TGF-beta score of G2 was significantly higher than G1 and G3 (p values were .006 and .017, respectively). There was no difference between TGF-beta staining scores of G2 and G4. Concomitant use of HMB/GLN/ARG appears to ameliorate radiation-induced acute intestinal toxicity; however, this finding should be clarified with further studies.

    A rare coexistence of thyroid lymphoma with papillary thyroid carcinoma
    (Medknow Publications & Media Pvt Ltd, 2013) Cakir, Murat; Celik, Esin; Tuncer, Fatma Betul; Tekin, Ahmet
    Diseases of the thyroid gland are frequently seen in general practice. Lymphoma of the thyroid is one of the rarest tumors. Its coexistence with papillary thyroid carcinoma is even rarer. Here, we present a 50-year-old female patient, who presented to our clinic with complaints of a rapidly growing lump on her neck, aphagia, and shortness of breath. A total thyroidectomy was performed. Histopathological analysis revealed the concomitant existence of papillary tumor. It should be noted that tumors with different histopathological behavior may rarely coexist with lymphoma in the thyroid gland. Masses growing rapidly in the thyroid shall suggest lymphoma.
