A 64-year-old female presented with an incidentally-discovered right posterior inferior cerebral artery (PICA) aneurysm, initially treated in 2015 by simple coiling. Follow-up demonstrated significant coil compaction that required retreatment. Retreatment was done uneventfully using a Pipeline embolization device (PED) shield deployed starting from the basilar artery and ending at the V4 segment of the vertebral artery. Eight-weeks post-deployment, a follow-up digital subtraction imaging (DSA) and intravascular imaging with optical coherence tomography were obtained. The intravascular imaging demonstrated that the flow diverter had good wall apposition and concentric neointimal growth over the braid with exception to the areas that the PED was not in contact with the endothelial wall, such as at the right PICA ostium and at the vertebrobasilar junction. The entire procedure was safe, and the patient had no complications. In this article, we describe for the first time the assessment of the status of endothelial “healing” of the PED shield at 8-weeks.

Background:
Slipped capital femoral epiphysis (SCFE) is a severe and catastrophic disorder that affects the hips of adolescents.Many reports about surgical procedures to treat this condition have been published, but to our knowledge, there are no published results of treatment in Latin American patients. This study describes the clinical and radiological results of the modified Dunn procedure with the surgical approach described by Ganz to treat mild to severe SCFE in a cohort of Colombian pediatric patients.
Methods:
We retrospectively analyzed 21 patients (22 hips) with SCFE treated with surgical dislocation of the hip from 2005 to 2017. The same pediatric orthopedic surgeon performed all operations. Clinical outcome was assessed using the range of movement and Merle d’Aubigné score, while radiological measurements and assessment included the slip angle and Tönnis score.
Results:
The average duration of follow-up was 29 months (range, 12–72 months). Of all cases, 17 presented with acute-on-chronic symptoms. Preoperatively, all 22 hips were classified as poor according to the Merle d’Aubigné score. Preoperative radiological classification showed compromise grade II or III in 20 hips. Last follow-up Merle d’Aubigné score rated 17 cases as good or excellent (p < 0.05). The postoperative radiological classification was grade I or II in all 22 cases, and the Tönnis score was stage II in 3 cases and stage III in 4 cases.
Conclusions
Our results suggest that the modified Dunn osteotomy performed through the Ganz technique could be safely and effectively used to treat patients with mild to severe SCFE.

Coil prolapse or migration is a rare but potentially serious complication that may occur during aneurysm embolization, with no standard management currently described. Here we describe our experience with the Embolus Retriever with Interlinked Cages (ERIC) device® (Microvention, Aliso Viejo, CA, USA) for the retrieval of prolapsed or migrated coils in a case series and Flow-Model analysis. First, a retrospective review was performed using our institution database for patients in which coil prolapse or migration occurred during aneurysm embolization, and data was collected and analyzed. Second, an in vitro Flow-Model analysis was performed comparing the ERIC device® with other stent retrievers for coil retrieval. In 2 cases, the ERIC device® successfully retrieved the displaced coil from intracranial circulation in 1 pass, after failure with other devices. In the Flow-Model, again the ERIC device® achieved success for retrieving a detached coil, whereas 2 other different stent retrievers failed to capture the coil after 2 attempts. The ERIC device® appears to be a safe and effective tool for retrieving a prolapsed or migrated coil from the intracranial circulation.

The implementation of imaging methods that enable sensitive and specific observation of anatomical structures has been a constant in the evolution of endodontic therapy. Conebeam computed tomography (CBCT) enables 3-dimensional (3D) spatial anatomical navigation in the 3 volumetric planes (sagittal, coronal and axial) which translates into great accuracy for the identification of endodontic pathologies/conditions. CBCT interpretation consists of 2 main components: (i) the generation of specific tasks of the image and (ii) the subsequent interpretation report. A systematic and reproducible method to review CBCT scans can improve the accuracy of the interpretation process, translating into greater precision in terms of diagnosis and planning of endodontic clinical procedures. MEDLINE (PubMed), Web of Science, Google Scholar, Embase and Scopus were searched from inception to March 2023. This narrative review addresses the theoretical concepts, elements of interpretation and applications of the CBCT scan in endodontics. In addition, the contents and rationale for reporting 3D endodontic imaging are discussed.

Purpose:
Despite advances in the treatment of adult acute lymphoblastic leukemia (ALL), relapse remains the most significant challenge in improving prognosis. Measurable residual disease (MRD) assessment can predict bone marrow relapse based on MRD positivity. As access to innovative therapies remains limited because of the high cost, chemotherapy is the widely utilized treatment option. The efficacy of a combination of bortezomib and Hyper-CVAD has been reported in patients with multiple myeloma; however, its efficacy has not yet been confirmed in patients with ALL.
Methods:
This prospective cohort study involved patients with ALL who presented with MRD-positive results or relapse and received treatment with a combination of bortezomib and Hyper-CVAD at two reference centers in Mexico City.
Results:
Of the 20 patients with positive MRD included in this study, 60% (n = 12) exhibited MRD negative results after combination treatment, 30% (n = 6) persisted positive MRD results, and 10% (n = 2) passed away. Of the 23 patients with bone marrow relapse, 43.5% (n = 10) achieved a second complete remission (2CR), 34.8% (n = 6) exhibited refractory status, and 21.7% (n = 5) passed away. To achieve a 2CR, 20% (n = 2) patients required less than four cycles of treatment, 50% (n = 5) required four cycles (two A and B cycles each), and 30% (n = 3) required six cycles.
Conclusion
The combination of bortezomib and Hyper-CVAD treatment exhibited better results in achieving MRD negative results, indicating its potential as a promising first-line treatment strategy for ALL.
