    Magnetic Resonance Imaging (MRI) in penile metastases of extragenitourinary cancers
    (Springer, 2006) Kendi, Tuba; Batislam, Ertan; Basar, M. Murad; Yılmaz, Erdal; Altınok, Deniz; Basar, Halil
    Background: The aim of present study is to evaluate the efficacy of magnetic resonance imaging (MRI) in different types of penile metastases. Materials and methods: In this report, we present three cases of penile metastases that have been developed secondary to extragenitourinary malignancies. Two of them did not have any primary malignancy history. Results: Penile biopsies were performed in all patients and metastatic penile tumours were found due to extragenitourinary malignancies. Penile MRI was performed before biopsies. The findings of MRI were correlated with histopathologic diagnosis. Moreover, penile MRI was found to be more sensitive in the evaluation of the lesions than ultrasonography. Conclusion: MRI can be accepted as a reliable non-invasive method for the evaluation of the extent of penile metastases and involvement of tunica albuginea or urethral.

    MRG ile normal görünümlü beyaz ve gri cevherde yaşlanmanın etkilerinin ADC değerleri ile saptanabilirliği
    (2004) Bilgili, Karadeniz Yasemin M.; Ünal, Birsen; Kendi, Tuba; Şimşir, İlknur; Erdal, Haydar; Huvaj, Sinef; Kara, Simay
    AMAÇ Çalışmamızda, MRG ile normal görünümlü beyaz ve gri cevherde, yaşlanma ile beyin dokusunda izlenen mikroskopik değişikliklerin, su difüzyonu değerinin matematiksel ölçümü olan ADC değeri (apparent diffusion coefficient= görünürdeki difüzyon katsayısı) ile saptanabilirliği araştırılmıştır. GEREÇ VE YÖNTEM MRG ve difüzyon ağırlıklı tetkikleri doğal olan, dekadlara göre sekiz alt gruba ayrılan 45 hastanın, "trace" ağırlıklı ADC haritaları kullanılarak, frontal ve oksipital beyaz cevherden ve talamustan ADC değerleri elde olundu. Elde olunan ADC değerlerinin artan hasta yaşı ile istatistiksel fark gösterip göstermediği araştırıldı. ADC ortalama değeri frontal beyaz cevherde 0.753±0.054 x 10-3 mm2/sn, okspital beyaz cevherde 0.673±0.085 x 10-3 mm2/sn, talamusta 0.763±0.063 x 10-3 mm2/sn olarak saptanmıştır. Frontal ve oksipital beyaz cevherde yaşla birlikte ADC değerlerinde istatistiksel olarak anlamlı artış saptanmış olmakla birlikte, talamusta yaşla ADC değerlerinde saptanan artış istatistiksel olarak farklılık oluşturmamaktadır. SONUÇ İlerleyen yaşla birlikte, MRG ile normal olarak saptanan beyaz cevherde, difüzyon ağırlıklı seriler ile su difüzyonunda artış saptanmış olup, bu veri yaşlanmanın getirdiği yapısal değişikliğin yansıması olarak düşünülmüştür.

    The Use of Computed Tomography to Determine Femoral Component Size A Study of Cadaver Femora
    (J Michael Ryan Publishing Inc, 2005) Uslu, Murad; Ozsar, Baris; Kendi, Tuba; Kara, Simay; Tekdemir, Ibrahim; Atik, O. Sahap
    Computed tomography is used to assess whether ideal femoral component size in knee arthroplasty can be made more accurately. Ideal femoral component size was measured on radiography, computed tomography, and by direct measurement of 20 cadaver femora and analyzed statistically. There was no significance between the tomographically anticipated ideal femoral component size and ideal femoral size values (Wilcoxon W 388.5; p 0.565). There was difference between radiographically anticipated ideal femoral size and ideal femoral size values (Wilcoxon W 324.5; p 0.020). Anticipating the ideal femoral size can be made more precisely with computed tomography than radiographs in cadaver femora. Anticipating the ideal femoral component size by computed tomography may solve the problems in in-between sizes. Future total knee designs may be manufactured in more anatomic sizes.

    Use of botulinum toxin type a for the treatment of masseteric muscle hypertrophy
    (B C Decker Inc, 2006) Arıkan, Osman Kürşat; Tan, Funda Uysal; Kendi, Tuba; Koç, Can
    We investigated the effectiveness of botulinum toxin A intramuscular injection for the management of masseteric muscle hypertrophy. Five patients with masseteric muscle hypertrophy were treated with botulinum toxin A (Dysport, Beaufour Ipsen, France). Clinical photographs were obtained before and between 3 and 6 months after application. Four patients are pleased with their present facial appearance. However, one patient reported mild discomfort about his appearance. Neither local nor general adverse effects were noted. Botulinum toxin A is a safe, easy-to-use, and effective nonsurgical option in the management of masseteric muscle hypertrophy. Its use is associated with a high degree of patient and physician satisfaction.
