1. The Role of Multiple Preoperative Regional Blocks in Combined Cosmetic Surgery: Enhancing Patient Satisfaction.
In a prospective comparative design, patients undergoing combined cosmetic procedures who received multiple preoperative, ultrasound-guided regional blocks used fewer painkillers, required no opioids, delayed their first request for additional analgesia, and reported higher satisfaction than controls. Demographics were similar across groups.
Impact: Demonstrates a practical, opioid-sparing analgesic strategy in aesthetic surgery that may improve recovery and satisfaction without adding systemic risk.
Clinical Implications: Adopting multimodal, preoperative regional anesthesia (erector spinae, PECS, and transversus abdominis plane blocks) in combined cosmetic surgeries can reduce postoperative pain, eliminate routine opioid use, and enhance patient satisfaction.
Key Findings
- Regional block group consumed fewer painkillers and used no opioids postoperatively.
- Time to first request for additional analgesia was longer and PRN analgesic requests were fewer in the block group.
- Patient satisfaction was higher with blocks: 45% very satisfied and 31% somewhat satisfied vs 12% and 32% in controls.
Methodological Strengths
- Prospective comparative design with clinically relevant endpoints (analgesic use, timing, satisfaction).
- Use of ultrasound-guided regional blocks reflecting real-world, reproducible practice.
Limitations
- Nonrandomized design with unspecified sample size limits causal inference and precision.
- Short-term outcomes; no data on long-term recovery, complications, or chronic pain.
Future Directions: Conduct adequately powered randomized trials comparing multimodal block strategies, assess long-term recovery and safety, and evaluate cost-effectiveness and workflow impact.
This prospective comparative study included patients who underwent multiple cosmetic procedures in a single surgical session. The study aimed to assess patient satisfaction regarding pain management and the extent of analgesic use. It included patients who underwent at least two procedures: abdominoplasty, breast surgery, liposuction of the abdomen, liposuction of the back, and buttock lipofilling. The patients were divided into two groups: the case group, which received more than one type of block: erector spinae plane, pectoral nerve, or transversus abdominis plane block, and the control group, which did not receive blocks. Most demographic characteristics and morbidities did not differ significantly between the two groups. The case group demonstrated reduced painkiller consumption, no use of opioid medication, fewer requests for as-needed analgesics, and a longer time to the first request for additional pain relief. The group that received preoperative nerve blocks had a significantly higher proportion of very satisfied and somewhat satisfied patients (45% and 31%, respectively) than those in the control group (12% and 32%, respectively). Preoperative ultrasound-guided blocks in combined cosmetic surgeries performed in a single session significantly reduce postoperative pain and opioid consumption while increasing patient satisfaction.Level of Evidence III This journal requires that authors assign a level of evidence to each article.

2. Quail Egg White-Gelatin Nanocomposite Films With rGO-ZnO-Ag Nanocomposite for Antimicrobial and Scar-Reducing Skin Regeneration.
A rGO-ZnO-Ag–embedded quail egg white–gelatin nanocomposite wound dressing showed broad antimicrobial activity (inhibition zones 14–30 mm; MICs 150–200 μg/mL) and reduced scar thickness in rat full-thickness wounds by day 21, with histological trends toward improved tissue organization.
Impact: Introduces a sustainable, multifunctional biomaterial that concurrently addresses infection control and scar reduction—two key needs in aesthetic and reconstructive wound care.
Clinical Implications: If translated to humans, such nanocomposite dressings could reduce infection risk from MDR organisms and minimize scarring, improving cosmetic outcomes and potentially lowering the need for revision procedures.
Key Findings
- Demonstrated broad-spectrum antimicrobial activity against S. aureus, E. coli, P. aeruginosa, Salmonella enterica, and C. albicans (inhibition zones 14–30 mm; MICs 150–200 μg/mL).
- All wounds achieved complete closure by day 21; nanoparticle-treated wounds showed ~4.5-fold scar thickness reduction vs GLT (p<0.0001).
- GLT-Qeg-W + NP films showed ~2-fold scar thickness reduction vs GLT-Qeg-W (p<0.01), with histology indicating improved epidermal restoration and adnexal regeneration.
Methodological Strengths
- Combined in vivo wound model with quantitative histology and antimicrobial susceptibility testing.
- Reported statistical significance with defined effect sizes and p-values.
Limitations
- Animal study with unspecified sample size; findings require validation in larger cohorts and in humans.
- Short follow-up (21 days) limits assessment of long-term remodeling and safety.
Future Directions: Evaluate biocompatibility, dosing, and long-term outcomes in large-animal models; perform controlled clinical trials to assess efficacy and safety in humans.
Effective wound healing requires dressings that support tissue regeneration while combating infection, particularly from multidrug-resistant (MDR) pathogens. This study developed and evaluated a multifunctional nanocomposite wound dressing composed of quail egg white (Qeg-W) and gelatin (GLT) embedded with rGO-ZnO-Ag nanoparticles. Nanocomposite films were prepared by incorporating rGO-ZnO-Ag into Qeg-W and applied to full-thickness skin wounds in rats. Wound closure was monitored over 21 days, and tissue samples were collected for histological assessment. Antimicrobial activity against MDR pathogens was evaluated using inhibition zone and MIC assays. The nanocomposite demonstrated robust antimicrobial activity against S. aureus, E. coli, P. aeruginosa, Salmonella enterica, and C. albicans (inhibition zones 14-30 mm; MICs 150-200 μg/mL). All wounds reached complete closure by day 21; however, NP-treated wounds were associated with significantly reduced scar thickness (~4.5-fold vs. GLT, p < 0.0001), while GLT-Qeg-W + NP wounds showed ~2-fold reduction vs. GLT-Qeg-W (p < 0.01). Histopathological evaluation indicated trends toward improved epidermal restoration and regeneration of dermal glands and hair follicles. Overall, GLT-Qeg-W nanocomposites embedded with rGO-ZnO-Ag nanoparticles exhibited strong standalone antimicrobial activity and were associated with reduced scarring and improved tissue organization. These findings suggest the potential of this sustainable, multifunctional system as a wound dressing, while highlighting the need for further studies to confirm these effects in larger cohorts.
3. Development of a web-based preoperative planner for right vertical infra-axillary thoracotomy.
A patient-specific, ray-casting–based web planner quantifies visibility of intracardiac targets and cannulation sites in RVIAT. In a dual-pathology validation, shifting the incision from the 4th to the 3rd intercostal space improved PDA visibility from 72% to 86% without compromising VSD exposure (100%); sensitivity analyses highlighted trade-offs for cannulation site exposure.
Impact: Introduces a deterministic, quantitative approach to preoperative planning that can balance cosmetic incision choices with adequate surgical exposure in pediatric cardiac surgery.
Clinical Implications: Surgeons can simulate and select intercostal incisions that maximize visibility of primary and secondary targets while maintaining safety, potentially improving outcomes and cosmetic results in RVIAT.
Key Findings
- Web-based planner computes a quantitative Visibility Score for multiple targets using patient-specific CT and ray-casting.
- In validation, the 3rd intercostal space improved PDA visibility to 86% vs 72% at the 4th, without reducing VSD exposure (100%).
- Sensitivity analysis showed robust visibility for deep intracardiac targets but reduced exposure of cannulation sites under varying conditions.
Methodological Strengths
- Patient-specific, geometry-driven modeling with quantitative metrics.
- Multi-parametric sensitivity analysis and real-time, client-side implementation.
Limitations
- Validated on a single complex case; lacks prospective clinical outcome data.
- Generalizability to diverse anatomies and surgical instruments remains untested in larger cohorts.
Future Directions: Prospective multicenter validation linking visibility metrics to intraoperative performance and outcomes; integration with VR/AR and instrument kinematics.
Right Vertical Infra-Axillary Thoracotomy (RVIAT) offers superior cosmetic outcomes but presents challenges due to restricted access. In pediatric patients, the 'crowded thorax' necessitates simultaneous visualization of intracardiac defects and central cannulation sites. Therefore, the choice of the intercostal incision can significantly affect the surgical field. To address this, we propose a patient-specific, geometry-driven framework to objectively optimize surgical corridors. A web-based surgical planner was developed to simulate incision strategies using patient-specific computed tomography data. The system utilizes ray-casting algorithms to compute a quantitative 'Visibility Score' for multiple anatomical targets. The framework was validated through a complex dual-pathology case and a multi-parametric sensitivity analysis involving varying chest wall thicknesses and instrument constraints. The system was successfully implemented as a platform-independent web application capable of real-time, client-side processing. In the dual-pathology validation, the simulation revealed that the standard 4th intercostal space (ICS) provided limited visibility for the secondary target (Patent Ductus Arteriosus, PDA: 72%). The optimizer identified the 3rd ICS as the superior vector, increasing PDA visibility to 86% without compromising primary Ventricular septal defect exposure (100%). Sensitivity analysis further indicated that while deep intracardiac targets maintained robust visibility across varying anatomical conditions, the exposure of cannulation sites was reduced. The proposed framework provides a deterministic method to evaluate surgical corridors preoperatively. By objectively quantifying exposure for both intracardiac defects and obligatory cannulation sites, the system assists surgeons in selecting the optimal incision level to ensure comprehensive procedural safety.
