    Endoscopy in the 15th Century
    (Georg Thieme Verlag Kg, 2002) Keskil, S.; Sabuncuoglu, H.
    The aim of this study was to investigate the contributions of Serefeddin Sabuncuoglu (1385-1468?) - who was born and practiced in Amasya in northern part of central Anatolia - to the field of endoscopy. He was a humble, curious and intelligent surgeon, and also a calligrapher and a miniature artist. This remarkable pioneer used the classification of the Andalusian surgeon, Abdul-Kasim Kalaf Ibni Abbas El Zahravi, known as Albucasis of Cordoba (936-1013); but improved it by adding many important and major new observations and chapters. He described "a thin and hollow tube of almost 35 cm, which was made of silver" and used it to inspect the interior of the bladder.

    Nocardia farcinica brain abscess: a case report and review of the literature
    (Sociedad Luso-Espanola Neurocirugia, 2004) Sabuncuoglu, H.; Açikgöz, Z.C.; Caydere, M.; Ustun, H.; Keskil, I.S.
    Nocardia infection is not rare as generally been assumed and its mortality rate is high. It is isolated from plants and soil in most regions of the worid. The hosts usually have predisposing conditions and the infection is acquired through the respiratory tract or skin. Nocardial organisms have a tendency to disseminate hematogenously from the primary site of infection to brain, kidney, joints, bones and eyes. Sulfonamides are preferred empirically for the treatment. Because of high relapse rates, the treatment must be continued for 12 months. In nocardia farcinica infection, the characteristic resistance pattern to cephalosporines must be kept in mind. In this article, a rare case of nocardia farcinica infection with a solitary cerebral abscess is presented and the literature is reviewed.

    Preliminary report on surgical mask induced deoxygenation during major surgery
    (Soc Espanola Neurocirugia, 2008) Beder, A.; Buyukkocak, U.; Sabuncuoglu, H.; Keskil, Z. A.; Keskil, S.
    Objectives. This study was undertaken to evaluate whether the surgeons' oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations. Methods. Repeated measures, longitudinal and prospective observational study was performed on 53 surgeons using a pulse oximeter pre and postoperatively. Results. Our study revealed a decrease in the oxygen saturation of arterial pulsations (SpO(2)) and a slight increase in pulse rates compared to preoperative values in all surgeon groups. The decrease was more prominent in the surgeons aged over 35. Conclusions. Considering our findings, pulse rates of the surgeon's increase and SpO(2) decrease after the first hour. This early change in SpO(2) may be either due to the facial mask or the operational stress. Since a very small decrease in saturation at this level, reflects a large decrease in PaO(2), our findings may have a clinical value for the health workers and the surgeons.
