Case Reports
Different Embolization Approaches for the Treatment of Posttraumatic Pseudoaneurysm of the Internal Maxillary Artery.
Pseudoaneurysm is an abnormal dilation of an artery that could be caused either by iatrogenic or traumatic events and it is associated with high rupture risk. Pseudoaneurysm rarely involves internal maxillary artery. ⋯ The authors described 2 different cases of internal maxillary artery pseudoaneurysm, treated by different embolization approaches. The first case was treated by a well-known arterial catheterism technique, whereas the second one was performed by an uncommon approach with a direct percutaneous puncture.

Multicenter Study
Persistent Opioid Use Among Children, Adolescents, and Young Adults After Common Cleft Operations.
Surgical care represents an important source of opioid prescribing and chronic use, but rates of prolonged opioid use following pediatric procedures remain unclear. The authors describe the rates and risk factors for new persistent opioid use in patients after common cleft operations. ⋯ New persistent opioid use occurs after cleft-related procedures and could lead to chronic use in children, adolescents, and young adults.

Comparative Study
Comparative Evaluation of the Prognostic Value Between the Ocular Trauma Score and the Pediatric Penetrating Ocular Trauma Score.
Controversy exists about the utility of the Ocular Trauma Score (OTS) in children. A new score was developed specifically for children-the Pediatric Penetrating Ocular Trauma Score (POTS)-which proved to be of prognostic value in young patients with penetrating eye injuries. The purpose of the study was to compare the prognostic value of OTS and POTS in children with open-globe injuries in a cohort of Brazilian children. ⋯ The association between OTS and achieved VA was good (Kendall Tau-b = 0.511, P = 0.001), as well as between POTS and achieved VA (Kendall Tau-b = 0.422, P = 0.002). The agreement between the predicted VA for OTS and POTS was fair (kappa = 0.400). In conclusion, in this small cohort of Brazilian children with open-globe injuries, there was no superiority of one score over the other and both OTS and POTS underestimated the potential best-corrected VA after treatment.

The topography, chemical features, surface charge, and hydrophilic nature of titanium implant surfaces are crucial factors for successful osseointegration. This study aimed to investigate the bone implant contact (BIC) ratio of titanium dental implants with different surface modification techniques using the rat femoral bone model. Sandblasted and acid washed (SL-AW), sandblasted (SL), resorbable blast material (RBM), microarc (MA), and sandblasted and microarc (SL-MA) surfaces were compared in this study. ⋯ Bone implant contact ratios were determined as follows: SL-AW: 59.26 ± 14.36%, SL: 66.01 ± 9.63%, RBM: 63.53 ± 11.23%, MA: 65.51 ± 10.3%, and SL-MA: 68.62 ± 6.6%. No statistically significant differences were found among the 5 different surfaced titanium implant groups (P > 0.05). Our results show that various implant surface modification techniques can provide favorable bone responses to the BIC of dental implants.

: Midfacial trauma commonly causes ocular injuries of varying degrees. Eye injuries account for approximately 10% of all battle injuries. Severity of injuries may range from a subconjunctival haemorrhage to optic nerve injury and globe laceration and rupture.
