Convergent experimental data, autobiographical studies, and investigations on daily life have all demonstrated that gathering information retrospectively is a highly dubious methodology. Retrospection is subject to multiple systematic distortions (i.e., affective valence effect, mood congruent memory effect, duration neglect; peak end rule) as it is based on (often biased) storage and recollection of memories of the original experience or the behavior that are of interest. The method of choice to circumvent these biases is the use of electronic diaries to collect self-reported symptoms, behaviors, or physiological processes in real time. Different terms have been used for this kind of methodology: ambulatory assessment, ecological momentary assessment, experience sampling method, and real-time data capture. Even though the terms differ, they have in common the use of computer-assisted methodology to assess self-reported symptoms, behaviors, or physiological processes, while the participant undergoes normal daily activities. In this review we discuss the main features and advantages of ambulatory assessment regarding clinical psychology and psychiatry: (a) the use of realtime assessment to circumvent biased recollection, (b) assessment in real life to enhance generalizability, (c) repeated assessment to investigate within person processes, (d) multimodal assessment, including psychological, physiological and behavioral data, (e) the opportunity to assess and investigate context-specific relationships, and (f) the possibility of giving feedback in real time. Using prototypic examples from the literature of clinical psychology and psychiatry, we demonstrate that ambulatory assessment can answer specific research questions better than laboratory or questionnaire studies.

Dynamic Navigation

Objectives: To present the use of dynamic navigation system in the repair of alveolar cleft. Patients and Participants: A total of three non-syndromic patients with unilateral alveolar cleft were involved in this study. Real-time computer-aided navigation were used to achieve restoration and reconstruction with standardized surgical technique. Methods: With the individual virtual 3-dimensional (3-D) modeling based on computed tomography (CT) data, preoperative planning and surgical simulation were carried out with the navigation system. During preoperative virtual planning, the defect volume or the quantity of graft is directly assessed at the surgical region. With the use of this system, the gingival periosteum flap incision can be tracked in real-time, and the bone graft can be navigated under the guidance of the 3-D views until it matches the preoperatively planned position. Results: Three patients with alveolar cleft were successfully performed under navigation guidance. Through the model alignment procedure, accurate matches between the actual intraoperative position and the CT images were achieved within the systematic error of 0.3 mm. The grafted bone was implanted according to the preoperative plan with the aid of instrument- and probe-based navigation. All the patients were healed well without serious complications. Conclusions: These findings suggest that image-guided surgical navigation, including preoperative planning, surgical simulation, postoperative assessment, and computer-assisted navigation was feasible and yielded good clinical outcomes. Clinical relevance: This dynamic navigation could be proved to be a valuable option for this complicated surgical procedure in the management of alveolar cleft repair.

Background Dialysis is often neglected in academic teaching. At the University of Torino, Italy, teaching Nephrology (4th year of Medical School) consists of 21 hours of formal lessons, 10 hours/student of interactive lessons (4/10 dedicated to dialysis) and 10 optional lessons (3 regarding dialysis). Interactive and optional lessons widely employ computer assisted teaching. Aim of the study was to evaluate student satisfaction on this approach. Methods Student satisfaction was assessed on 4 sample lessons (166 students), by two short dedicated questionnaires (0–10 scale, open questions). Results High scores were given to the dialysis lessons (median 8/10). Computer assisted interface (median 8/10, range 6–10) was of help in check of knowledge in real time (86%), enhancing participation (61%); 62% suggest extending this experience to selected courses, 38% to all. Conclusions Medical students consider dialysis an important part of the academic teaching of Nephrology; new interfaces may help to enhance student satisfaction.

Abstract We developed of computer programs to evaluate the clinical reliability of test results by comparing each new result with previous results for the same patient, and to signal discrepancies in real time. These "delta check" discrepancies are noted, and they must be reviewed by the laboratory staff before results can appear on a patient's record. During a month, I reviewed 1403 such delta check messages and detected 55 (3.9%) that could not be explained on the basis of the patient's clinical condition. Of these, 23 represented true laboratory errors, which were corrected. The recognition of discrepancies before they appear on patients' reports has facilitated the operation of the clinical chemistry laboratory. Mislabeled and otherwise mishandled specimens are discovered before erroneous results appear on a patient's record.

Freehand Technique

Three-dimensional (3D) navigation using a computer-assisted technique is being increasingly performed in minimally invasive surgical procedures because it can provide stereoscopic information regarding the operating field to the surgeon. In this paper, the development of a real-time arthroscopic system utilizing an endoscopic camera and optical fiber to navigate a normal vector for a reconstructed knee joint surface is described. A specific navigation approach suitable for use in a rendered surface was presented in extenso. A small-sized endoscopic tube was utilized arthroscopically on a cadaveric knee joint to show the potential application of the developed system. Experimental results of underwater navigation on a synthetic knee joint showed that our system allows for a higher accuracy than a freehand technique. The mean angle of navigation for the proposed technique is 9.5circ (range, 5circ to 17circ; SD, 2.86circ) versus 14.8circ (range, 6circ to 26circ; SD, 7.53circ) and 12.6circ (range, 4circ to 17circ; SD, 3.98circ) for two sites using a freehand technique.
