    Evaluation of differences between observers and automatic-manual measurements in calculation of Doppler parameters
    (Wiley, 2004) Unal, B; Bagcier, S; Simsir, I; Bilgili, Y; Kara, S
    Objective. We aimed to search for differences between observers and automatic and manual measurements in calculations of Doppler parameters. Methods. The middle cerebral artery (MCA), central retinal artery, ophthalmic artery (OA), common carotid artery (CCA), vertebral artery (VA), popliteal artery (PA), interlobar renal artery (IRA), and arcuate renal artery (ARA) were evaluated in 20 healthy subjects bilaterally Peak systolic velocity (PSV), end-diastolic velocity (EDV), time-averaged maximum velocity (TAMAX), resistive index (RI), and pulsatility index (Pi) were measured from the same spectrum manually by 3 observers and automatically. Results of 4 measurements were compared by analysis of variance and Pearson tests. Results. The comparison of the 4 measurements revealed significant differences for most parameters except TAMAX of the OA, VA, and ARA and PSV EDV and PI of the PA. An automatic calculator yielded lower PSV, RI, and PI values (except the MCA and PA) and higher EDV values compared with manual measurements. The magnitudes of difference were in the range of 1% to 16% for velocities and 4% to 14% for RI and PI. The means of difference were 3.185 cm/s for PSV of the CCA and 0.054 for RI of the IRA. Correlation was high for PSV, EDV, and TAMAX in all arteries (except TAMAX of PA) and relatively low for PI and RI in most of the arteries. Conclusions. Although our study was performed on healthy subjects, our results showed that, in most cases, readers and the automatic approach disagreed on evaluation of Doppler parameters. This may be important in preventing false diagnoses in cases with Doppler values close to upper limits and may necessitate establishment of new limits for each method.

    Imaging in the diagnosis of symptomatic forearm muscle herniation
    (Springer-Verlag, 2003) Kendi, TK; Altinok, D; Erdal, HH; Kara, S
    Muscle herniation can be defined as protrusion of a portion of muscle through an acquired or congenital defect of enclosing fascia. Although it is usually a cosmetic problem, it can lead to local pain and tenderness after prolonged exertion. In this report, we present a case of flexor digitorum superficialis muscle herniation in a 58-year-old man. The radiographic, ultrasonographic and magnetic resonance imaging findings are described with dynamic examination, permitting demonstration of muscle herniation through the fascial defect during muscle contraction.

    Isolated late penile metastasis of an adenocarcinoma of the rectum
    (Karger, 2004) Yilmaz, E; Batislam, E; Altinok, G; Altinok, D; Kara, S; Basar, M
    Penile metastatic tumors are relatively infrequent and very rare compared to extraurogenital tumor metastasis. We present an interesting rare occurrence of a late penile metastasis on an adenocarcinoma of the rectum. Copyright (C) 2004 S. Karger AG, Basel.

    Late-onset ureteric urinoma with intermittent jet flow as a complication of ureterolithotomy
    (John Wiley & Sons Inc, 2004) Unal, B; Basar, H; Bilgili, MYK; Basar, M; Batislam, E; Erdal, HH; Kara, S
    We present the case of a late-onset urinoma in a 47-year-old man with a history of right ureterolithotomy performed 6 months previously, following 2 unsuccessful attempts at extracorporeal shock wave lithotripsy. The ipsilateral kidney was nonfunctional and hydronephrotic. The urinoma did not show enhancement on contrast-enhanced CT and intravenous pyelography. Sonography revealed turbulence in the urinoma and jet flow from the ureter. Lab studies of fluid obtained by percutaneous puncture and aspiration yielded misleading findings for urine and revealed the presence of hemosiderin-laden macrophages. The urinoma was surgically resected and ureteroneocystostomy was performed. (C) 2004 Wiley Periodicals, Inc.
