1. The role of compounded mouthwash with or without acyclovir in managing chemotherapy-induced oral mucositis in cancer patients: a randomized controlled trial.
In a double-blind RCT of 110 hematologic oncology patients, an acyclovir-containing compounded mouthwash reduced CIOM incidence (25.5% vs 45.5; p=0.028), shortened duration (median 4.5 vs 7.5 days; p=0.01), and eliminated grade 3 events compared with control. Logistic regression supported a protective effect (OR 2.444; p=0.03).
Impact: Provides randomized evidence that a simple formulation change (adding acyclovir) meaningfully improves CIOM outcomes in high-risk patients, addressing a common unmet need in supportive oncology care.
Clinical Implications: Clinicians may consider acyclovir-containing compounded mouthwash as part of prophylaxis or early management for CIOM in hematologic chemotherapy or transplant settings, pending confirmation in larger multicenter trials.
Key Findings
- CIOM incidence was lower with acyclovir mouthwash (25.5%) vs control (45.5%; p=0.028).
- Mucositis duration was shorter with acyclovir (median 4.5 vs 7.5 days; p=0.01).
- No grade 3 mucositis occurred in the acyclovir arm vs five cases in control (p=0.045).
- Logistic regression supported a protective effect (OR 2.444; p=0.03).
Methodological Strengths
- Prospective, double-blind randomized controlled design with standardized WHO mucositis grading.
- Multivariable logistic regression corroborating primary findings.
Limitations
- Single-center, modest sample size limits generalizability.
- Trial registration and detailed mouthwash composition beyond acyclovir not reported; no long-term outcomes.
Future Directions: Conduct multicenter, adequately powered RCTs, standardize formulation and dosing, assess safety, patient-reported outcomes, and cost-effectiveness, and test across cancer types and regimens.
2. Profilometric and scanning electron microscopy analysis comparing hydroxyapatite and zinc oxide nanoparticles for erosion resistance.
In an in vitro study using 27 dentin discs, ZnO nanoparticle-loaded CMC hydrogel achieved greater dentinal tubule occlusion and superior erosion resistance than hydroxyapatite nanoparticles, while etched controls had the roughest surfaces and most open tubules. ImageJ quantification corroborated SEM observations.
Impact: Identifies ZnO nanoparticles as a promising desensitizing material with better erosion resistance and tubule occlusion than hydroxyapatite, informing the design of next-generation treatments for dentin hypersensitivity.
Clinical Implications: Supports prioritizing ZnO nanoparticle formulations for future clinical desensitizing products; requires clinical trials to validate pain reduction, durability, and safety.
Key Findings
- Etched controls showed highest surface roughness and most unoccluded dentinal tubules.
- ZnO nanoparticle group achieved more dentinal tubule occlusion than hydroxyapatite group by SEM and ImageJ quantification.
- ZnO nanoparticles demonstrated superior resistance to erosive wear compared with hydroxyapatite nanoparticles.
- Group II (hydroxyapatite) had lower SRa than Group III (ZnO), but ZnO showed better functional occlusion and erosion resistance.
Methodological Strengths
- Random allocation across three groups with controlled in vitro conditions.
- Multi-modal assessment combining profilometry, SEM, and ImageJ-based quantification.
Limitations
- In vitro design with extracted teeth; no clinical pain or sensitivity outcomes.
- Small sample size and evaluation limited to two nanoparticle types and a 7-day protocol.
Future Directions: Advance to randomized clinical trials assessing patient-reported sensitivity reduction, longevity under dietary acids, and biocompatibility; optimize nanoparticle loading and hydrogel carriers.
3. "Open book facial dissection" : an ideal pedagogical approach for learning safe and effective fillers and botulinum toxin injection techniques.
The authors describe an "open book" facial dissection pedagogy that exposes layered anatomy on one hemiface and performs comparative injection demonstrations on the other, mapping ageing changes and risk zones to optimize filler and botulinum toxin injection planning.
Impact: Addresses a critical training need by directly linking layered anatomical structures to injection techniques and risks, potentially reducing complications in aesthetic practice.
Clinical Implications: Adoption of this structured dissection-based curriculum could standardize injector training, enhance recognition of danger zones, and improve safety for cosmetic filler and toxin procedures.
Key Findings
- Introduces a reproducible "open book" dissection that visualizes skin, superficial fat, SMAS, and deep fat in layers on one hemiface.
- Provides a contralateral comparative injection demonstration to link anatomy with clinical technique, including site, depth, and risk.
- Demonstrates ageing processes and corrective injection targets to justify injection planning.
Methodological Strengths
- Layered, visual pedagogy that directly connects anatomical structures to clinical injection parameters.
- Structured and reproducible dissection approach facilitating risk visualization.
Limitations
- Descriptive educational report without quantitative learner outcomes or comparative evaluation.
- Generalizability and impact on complication rates remain untested in prospective studies.
Future Directions: Prospectively evaluate competency gains, complication rates, and knowledge retention; compare against standard curricula; explore integration with simulation/AR/VR.
