AI Article Synopsis
- This study aimed to identify risk factors for graft infection after cranioplasty, as understanding these can help reduce infection rates.
- Six out of 85 patients (7.05%) developed graft infections, which were linked to specific factors such as long surgery times, prior temporalis muscle removal, and preoperative fluid collection.
- Strategies to avoid long operations and minimize surgery-related complications are recommended to lower the incidence of graft infections.
Article Abstract
Background: The predictors of graft infection after cranioplasty (GIC) following decompressive craniectomy are not well established. Knowledge of the risk factors for GIC will allow development of preventive measures designed to reduce infection rates. Therefore, the objective of this study was to identify risk factors for the development of GIC.
Methods: A total of 85 patients underwent reconstructive cranioplasty after decompressive craniectomy between January 2009 and July 2011 and had a follow-up period of > 1 year; charts were reviewed retrospectively. Although autograft was used whenever possible, artificial bone was used for cranioplasty. GIC was defined as infection requiring removal of the bone graft.
Results: GIC occurred in six patients (7.05 %). GIC was not related to the indications for craniectomy, the interval of cranioplasty, graft material, or the size of the bone defect (p = 0.433, p = 0.206, p = 0.665, and p = 0.999, respectively). The GIC rate was significantly related to previous temporalis muscle resection, preoperative subgaleal fluid collection, operative times > 120 min, and postoperative wound disruptions (p = 0.001, p < 0.001, p = 0.035, and p = 0.016, respectively). Multiple logistic regression showed that the presence of a subgaleal fluid collection before cranioplasty significantly increased the risk of GIC (OR: 38.53; 95 % CI: 2.77-535.6; p = 0.006).
Conclusions: The results of this study suggest that long operative times (> 120 min), craniectomy with temporalis muscle resection, the presence of preoperative subgaleal fluid collection, and postoperative wound disruption may be risk factors for graft infection after cranioplasty. Surgical techniques should be developed to reduce operative time and to avoid temporalis muscle resection when possible. In addition, meticulous dural closure aimed at reducing the formation of subgaleal fluid collection is important for the prevention of graft infections after cranioplasty.

Q fever is a zoonotic disease caused by the Gram-negative bacterium , typically transmitted through exposure to infected animal secretions. As the clinical signs of Q-fever are largely non-specific in humans, a definitive diagnosis can often be overlooked, particularly when physicians fail to consider on the list of differentials. This case report describes Q-fever in a male patient who had previously undergone orthotopic liver transplantation.

This review synthesizes key findings from the past five years of experimental literature, elucidating the gut microbiome's significant influence on the pathogenesis of thyroid diseases. A pronounced shift in the gut microbiota composition has been consistently observed, with a significant reduction in bacteria such as , , , and , and a notable increase in bacteria, including , , , , and . These alterations are implicated in the development and progression of thyroid diseases by impacting metabolic pathways including bile acid and cytokine production, including a decrease in short-chain fatty acids (SCFAs) that are crucial for immune regulation and thyroid hormone homeostasis.

Background: A new induction therapy strategy of a single 3 mg/kg dose of rabbit antithymocyte globulin (r-ATG) showed a lower incidence of acute rejection.
Methods: The objective of this study was to use real-world data to determine the incremental cost-effectiveness ratio (ICER) of r-ATG induction for the prevention of acute rejection (AR) in the first year following kidney transplantation and for kidney graft survival over 1, 4, and 10 years of post-transplantation from the perspective of the national public healthcare system. A Markov state transition model was developed utilizing real-world data extracted from medical invoices from a single center.
