Objective: The study presented in this article assesses the effectiveness of adjuvant electron beam radiotherapy (RT) in reducing keloid recurrence and improving scar-related outcomes.

Methods: The retrospective study included 32 patients with 36 keloid scars who underwent surgical excision and adjuvant electron beam RT. The patient and observer scar assessment scale patient and observer scar assessment scale was used for all patients after RT.

Results: The results showed no major treatment-related adverse events, and significant correlations were observed between overall score and color, stiffness, thickness, and irregularity of keloid scars. The study highlights that electron beam RT is an effective adjuvant therapy in reducing keloid recurrence and improving scar-related outcomes.

Conclusion: Surgical excision combined with adjuvant RT is an excellent treatment option for keloids, with high patient satisfaction and low recurrence rates.

Objective: Create three-dimensional anatomical and augmented reality models for the study of neuroanatomy, from cadaveric models using photogrammetry for three-dimensional reconstruction, comparing two software, one fully automated and the other semi-automated with classic books for the study of neuroanatomy.

Method: Three-dimensional anatomical models were created through the photogrammetry technique and by means of two software. The objects were evaluated by the neurosurgery residents.

Results: Three three-dimensional anatomical models were created from photogrammetry for each program and evaluated with a survey applied to 23 neurosurgery residents.

Conclusions: There is no significant difference between the 3DF Zephyr^© 2021 3Dflow tool for creating anatomical three-dimensional objects in a semi-automated way compared to Autodesk ReCap Photo 22.1 Automated Software^© 2021 Autodesk, Inc. The residents consider that the models made in this work are useful in learning neuroanatomy.

The iliac crest graft is the ideal source of autologous bone graft. It is a procedure that is associated with few complications. Iliac hernia is a rare complication that appears especially when full-thickness grafts are taken. It is more common in females and the main symptom is pain in the graft area. Surgical treatment is recommended due to the risk of incarceration as these hernias may contain abdominal viscera. There is no standard treatment for these hernias.

Intestinal malrotation refers to the incomplete rotation of the primitive intestine around the vitelline sac or superior mesenteric artery. It is frequently found on the first days of extrauterine life or in adult life, as an incidental finding or with obstructive symptoms. We present a case of intestinal obstruction due to intestinal malrotation in a male adult, who underwent urgent surgical abdominal exploration.

Objective: To perform a translation and cultural adaptation into Spanish of the IKDC-Subjective Knee Form and Tegner Activity Score (TAS). They are very relevant and widely used subjective scales, but their Spanish version is not available.

Methods: The ISPOR guide methodology was followed. It is structured in ten stages: 1) preparation, 2) forward translation (two translations from English to Spanish), 3) reconciliation (unification of the two Spanish versions), 4) back translation (translation of the Spanish unified version into English), 5) back translation review (comparison with the original scale), 6) harmonization, 7) cognitive debriefing (assessment of the scale comprehensibility: 10 patients and 10 doctors), 8) review of cognitive debriefing, 9) proofreading, and 10) final report.

Results: The IKDC-Subjective scale and TAS have been translated and culturally adapted into Spanish. When comparing the back translation into English and the original English version, a complete conceptual equivalence was observed in all the items. The comprehension tests of both scales showed that all the items were "clearly comprehensible".

Conclusions: It is recommended to use the current Spanish versions of the IKDC-Subjective knee form and the TAS when applying these scales to Spanish-speaking patients.

Objective: We aimed to evaluate the relationship between emergence agitation and pre-operative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) after rhinoplasty.

Methods: Our study included 104 patients. All patients underwent surgery under standard general anesthesia. In the pre-operative period, receiver operating curve analysis was performed to determine the cutoff values of NLR and PLR for the risk of emergence agitation and pre-operative anxiety. A correlation analysis was performed between NLR and PLR, the State-Trait Anxiety Inventory scale, and the body image disturbance scale.

Results: While the area under the curve (AUC) value of NLR for emergence agitation was not significant (p = 0.76), the cutoff value for PLR was 113.37 (AUC = 0.624, sensitivity = 80.65%, specificity = 45.21%, p = 0.046). Median PLR values were higher in patients with emergence agitation (p = 0.046). The AUC value for pre-operative anxiety was not significant. There was no correlation between NLR and PLR and the scales assessed.

Conclusions: We suggest that PLR may be a predictive biomarker in evaluating the risk of pre-operative emergence agitation in patients scheduled for rhinoplasty.

Objective: Analyze the approach of the multilayer flow modulator (MFM) based on the results obtained in patients treated with Stena MFM^® (S-MFM).

Methods: It was evaluated 6-month follow-up outcomes of 12 patients (nine men and three females; mean age 60 years, range 34-79 years) underwent aneurysm repair with the S-MFM between July 2022 and December 2022. All patients undergoing S-MFM were patients at high risk of mortality and/or morbidity for open surgical repair and endovascular aneurysm repair, including thoracic Endovascular Aortic Repair (TEVAR) or fenestrated endovascular aortic repair (FEVAR).

Results: The control angiograms confirmed successful patency in the lumen of the main aorta and the branches in all cases. Complete aneurysm thrombosis was detected in all patients on computed tomography angiography at 6-month follow-up. The technical success was 100%, and no case required immediate intervention. Significant complications, such as ruptures, stent migrations, retractions, thrombosis, fractures were not observed.

Conclusions: The present data show the MFM approach may be an attractive alternative for complex aortic aneurysms. While it shrinks the aneurysm sac and protects the side branch blood flow, it reduces mortality and morbidity risks.
