    Coexistence of Glomangioma and Yolk Sac Tumour in a Child: A Case Report
    (Premchand Shantidevi Research Foundation, 2014) Kose, Dogan; Toy, Hatice; Gunel, Engin; CaliSkan, Umran; Koksal, Yavuz
    Glomus tumours (GTs) primarily arise from glomus bodies that are located in the dermis layer of skin. However, they can be encountered ectopically in most parts of the body. As a result of researches done in a 17-month-old male patient who prssented to us with complaint of an increasingly growing swelling, he was diagnosed with a yolk sac tumour. Chemotherapy was started and then, he was operated. GT was found inside the tumoural mass. Our patient, who is the first case according to our knowledge, where the concurrence of yolk sac and glomus tumours was reported, has been discussed in the light of literature.

    Effects of Prednisolone, l-Asparaginase, Gemfibrozil, and Combinations of These Elements on Mice Lipid Profile, Liver, and Pancreas
    (Lippincott Williams & Wilkins, 2016) Kose, Dogan; Tarakci, Nuriye; Celik, Zeliha Esin; Vatansev, Husamettin; Cimbek, Emine Ayca; Ugras, Serdar; Sen, Yasar
    The aim of this study is to determine the effects of l-asparaginase (l-ASP), corticosteroids (CSs), and antilipidemics, separately and in combination, on the lipid profiles and the liver and pancreas histology in mice. This study included 8 groups of 7 mice each. Before any drug administration, serum samples were taken from all of the mice. Then, normal saline was applied to the control group, and a medication or combination of medications was applied to the other groups. Levels of triglycerides, cholesterol (COL), and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were determined, and the livers and pancreases were evaluated histologically at the end of the study. Triglycerides increased significantly in the CS-only and the l-ASP-only groups, COL increased significantly in the CS-only group, and HDL increased significantly in the CS-only and the antilipidemic-only groups. LDL was significantly lower in the CS-only and the l-ASP-only groups. CSs and l-ASP were significantly effective in liver necrosis, l-ASP was significantly effective in liver balloon degeneration, and CS were significantly effective in pancreas vacuolization. Triglyceride measurement is recommended before/during CS and/or l-ASP treatment. Starting with an antilipidemic agent can be considered to avoid possible complications in patients with significantly high rates. Indicators of a possible liver or pancreas injury should also be considered.

    Pilomatrixoma in childhood
    (Medknow Publications & Media Pvt Ltd, 2014) Kose, Dogan; Ciftci, Ilhan; Harmankaya, Ismail; Ugras, Serdar; Caliskan, Umran; Koksal, Yavuz
    Context: Pilomatrixoma is a benign tumor of the skin. Malignant transformation can be seen rarely in the small percentage. Aim: The aim of the following study is to attract attention to this tumor in the differential diagnosis because if it is not kept in mind it leads to both unnecessary interventions and treatments for the patient. Patients and Methods: From January 2006 to December 2012, 8 patients with pilomatrixoma were evaluated retrospectively. Results: A total of 8 pediatric pilomatrixoma patients charts were reviewed retrospectively. None of the patients had familial feature. Of 8 patients 4 (50%) were male and 4 (50%) were female. The patients age ranged from 2-18 years with a median age 11.5 years. All of the patients were admitted with the complaint of swelling at the lesion site. Two patients have multiple lesions, one of them has two and other has three lesions. A total of 11 lesion were detected in our 8 patients that 5 of them were located upper extremities (46%), 3 of them cervical region (27%), 2 of them on occipital region (18%) and 1 of them in the sacral region (9%). All lesions were excised completely. Until now, no patient had evidence of recurrence or malignant disease. Conclusion: As a result pilomatrixoma is a benign tumor, with atypical forms and unfortunately, no tumor-specific diagnostic feature except of a careful histopathological examination is available.
