The learning curve in the acquisition of psychomotor skills varies among individuals, and studies about laparoscopy indicate that the difference can be predicted using spatial ability tests. We examined the association between the results of such tests and the learning curve in ETSS to determine the need for a personalized curriculum for ETSS skill training. A total of 30 fifth-year medical students from Kindai University School of Medicine (17 men, 13 women; mean age, 26 years) without ETSS experience completed the spatial orientation test (SOT) for the measurement of spatial visualization ability. They performed the dural incision task (DIT) twice on an ETSS training model for surgical psychomotor skill evaluation. The SOT scores (angle errors) exhibited substantial individual differences in spatial visualization ability, whereas the DIT scores significantly improved in the second trial (Wilcoxon signed-rank test, P = 0.0035). However, no significant difference was observed in the DIT scores between the smaller error and larger error groups of the SOT. The results indicated that two DIT trials were sufficient to acquire psychomotor skills for the DIT as the endoscope was almost fixed and learning only one viewpoint and line of sight combination was adequate. In conclusion, a personalized ETSS training program based on the trainee's spatial ability is not necessary for the DIT. Further research is warranted to determine the effect of spatial ability on more complex tasks, such as suturing in cranial base repair.</p>","PeriodicalId":19225,"journal":{"name":"Neurologia medico-chirurgica","volume":" ","pages":"395-400"},"PeriodicalIF":2.4,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11617353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142350929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the morphology of LSR and the course of recovery of the compound motor action potential (CMAP), to better understand the pathophysiology of delayed healing of HFS. Based on the pattern of the initial LSR morphology on temporal and marginal mandibular branches stimulation, patients were divided into two groups: the monophasic and polyphasic groups. The results of MVD surgery and sequential changes in the CMAP were evaluated 1 week, 1 month, 1 year, and final follow-up after the surgery. Significantly higher rates of persistent postoperative HFS were observed in patients with the polyphasic type of initial LSR at 1 week and 1 month after the surgery (P < 0.05, respectively). In the polyphasic group, the amplitude of the CMAP tended to gradually improve with time, while in the monophasic group, the amplitude of the CMAP decreased on the seventh postoperative day, followed by its gradual improvement. There is a significant correlation between delayed relief after MVD and polyphasic morphology of the initial LSR in patients with HFS.

We examined the behavior of several stent-filter-based EPD combinations, focusing on their propensity to become trapped or disengage in vitro. Four physicians subjectively rated the force required to result in trapping using a 5-point scale. Moreover, the force required to disengage trapped devices was evaluated. The Casper stent-Spider FX EPD combination was difficult to disengage when entrapment occurred, which suggested that this phenomenon tended to occur with this combination.

Radiation data and clinical features of 70 patients who underwent coil embolization between 2015 and 2020 were retrospectively analyzed. Since July 2017, the pulse rate was regulated from 7.5 to 4 frames per second (f/s). Statistical analyses were performed to examine the correlation between pulse rate and radiation exposure. Out of the 70 procedures, 30 were performed at the standard pulse rate (7.5 f/s), and 40 were performed at the lower pulse rate (4 f/s). In the lower-pulse-rate group, the absorbed dose to the patient (AK) was 2580.7 (±217) mGy, whereas in the standard-pulse-rate group, it was 4760 (±411.1). Both the dose-area product (DAP) and AK were substantially reduced in the low pulse rate group (p = 0.000002). There was a significant correlation between DAP and AK and pulse rate (p = 0.004, p = 0.0017, respectively).
