Objective: The objective of our study was to determine how well CT predicts the need for laparotomy in hemodynamically stable patients with penetrating abdominal injury.
Materials And Methods: We reviewed MEDLINE articles published from January 1994 through June 2008. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and accuracy were calculated for each source and collectively using a meta-analysis.
Results: Of 180 relevant studies, five were included in the meta-analysis. Pooled weighted estimates of sensitivity, specificity, NPV, PPV, and accuracy were 94.90%, 95.38%, 98.62%, 84.51%, and 94.70%, respectively.
Conclusion: CT in patients with penetrating abdominal trauma has high sensitivity, specificity, NPV, and accuracy, but has lower PPV in determining the need for laparotomy. It follows that CT is an indispensable tool in predicting the need for laparotomy in these patients but still has room for improvement.

Background: Penetrating cardiac trauma is an entity with high pre and intrahospital mortality due to complications such as cardiac tamponade and massive hemothorax. A ventricular septal defect (VSD) occurs in 1-5% of cases and can present early or late. The management strategy for VSD resulting from penetrating cardiac trauma is uncertain.

Transdermal drug delivery (TDD) represents a transformative paradigm in drug administration, offering advantages such as controlled drug release, enhanced patient adherence, and circumvention of hepatic first-pass metabolism. Despite these benefits, the inherent barrier function of the skin, primarily attributed to the stratum corneum, remains a significant impediment to the efficient permeation of therapeutic agents. Recent advancements have focused on macromolecular-assisted permeation enhancers, including carbohydrates, lipids, amino acids, nucleic acids, and cell-penetrating peptides, which modulate skin permeability by transiently altering its structural integrity.

Recent advances have highlighted the ability of certain antibody "shuttles'' to traverse the BBB and enhance the delivery of diverse therapeutic payloads. However the true potential of this approach remains underexplored and is limited by traditional in vitro screening platforms that fail to capture the complexities of in vivo biology.
