Unusual arterial supply of the segment IV with interlobar bridge and right replaced hepatic artery: a case report

A replaced right hepatic artery (RHA) arising from the superior mesenteric artery and an interlobar parenchymal bridge over the sagittal fissure have been observed on a 64-year-old formalin-fixed male cadaver in the anatomy laboratory. As we had followed a detailed segmental anatomy, we encountered an arterial distribution of segment IV featuring a different pattern from the literature so far. According to our observations, the segment I is supplied by both left (LHA) and middle (MHA) hepatic arteries; the segments II and III are supplied by the LHA while the segment IV is supplied by both the MHA and replaced RHA. The segments V–VIII are supplied only by the replaced RHA.  The case emphasizes the importance of arterial variations of liver in terms of the surgical procedures during the liver transplantation, hepatic resections, hepatic tumours, and etc. Our discussion focuses to the arterial supply of the segment IV and possible complications it may cause during/after the liver operations.

Is the use of videotape recording superior to verbal feedback alone in the teaching of clinical skills?

<p>Abstract</p> <p>Background</p> <p>In recent times, medical schools have committed to developing good communication and history taking skills in students. However, there remains an unresolved question as to which constitutes the best educational method. Our study aims to investigate whether the use of videotape recording is superior to verbal feedback alone in the teaching of clinical skills and the role of student self-assessment on history taking and communication skills.</p> <p>Methods</p> <p>A randomized controlled trial was designed. The study was conducted with 52 of the Dokuz Eylul University Faculty of Medicine second year students. All students' performances of communication and history taking skills were assessed twice. Between these assessments, the study group had received both verbal and visual feedback by watching their video recordings on patient interview; the control group received only verbal feedback from the teacher.</p> <p>Results</p> <p>Although the self-assessment of the students did not change significantly, assessors' ratings increased significantly for videotaped interviews at the second time.</p> <p>Conclusions</p> <p>Feedback based on videotaped interviews is superior to the feedback given solely based on the observation of assessors.</p

Decolorization of simulated textile wastewater in an anaerobic-aerobic sequential treatment system

The effects of hydraulic retention time (theta(H) = 12-72 h), initial COD concentration (COD0 = 1000-8000 mg l(-1)) and initial dyestuff concentration (D-0 = 50-400 mg l(-1)) on COD removal and decolorization of vinylsulfone/monochlorotiazine bifunctional, monoazo type textile dyestuff, Reactive Red 195, Sumifix Supra Br Red 31317 150% gran in a sequential anaerobic-aerobic treatment system were investigated in this study. A facultative anaerobic PDW was used as dominant microbial culture in the anaerobic unit for decolorization. The system was operated continuously at room temperature (T = 19-22 degreesC). It consisted of an anaerobic packed column and a conventional activated sludge unit which was fed with effluent from an anaerobic unit. Metal mesh particles were used as microorganism support material in the anaerobic packed column. Experimental results indicated that the system could be operated at theta(H) = 18 h, 3000 mg l(-1) initial COD concentration and 100 mg l(-1) dyestuff concentration to obtain over 85% decolorization efficiency in an anaerobic reactor. No significant colour removal (15%) was observed under aerobic conditions while COD removal was mainly obtained in the aerobic unit with maximum 90% efficiency. (C) 2002 Elsevier Science Ltd.

Incisional Light-Guided Intervention (Ilgi) Technique for Urethral Stricture Treatment

A male urethral stricture is common problems of the low urinary tract secondary to the transurethral procedure etc.. In this paper, we define a technique is the composition of the using flexible cystoscopy and internal urethrotomy simultaneously with two different surgeons. This method is an acceptable in patients who have multiple comorbidities, high risks and follow up with indwelling urethral catheterization

First Case of Right Malrotated Kidney Transplantation

Vascular anatomy may widely vary in malrotated kidneys, depending on the degree of rotation. Polar arteries and venules are often accompanied by structural and positional anomalies of the kidney that can make donor nephrectomy more complicated. Detailed evaluation of the donor before surgery is very important for both surgeon and patient. In particular, vascular anatomy should be evaluated in detail by modern imaging methods in donor nephrectomy. Herein we share our experience with right malrotated kidney open donor nephrectomy
