Background: Pediatric tibial fractures are common long-bone injuries, yet uncertainty remains in the optimal immobilization strategy. The comparative effectiveness and safety of short leg versus long leg casts in achieving stable healing and functional recovery have not been clearly established. Methods: A literature search was conducted across Medline, CINAHL, Embase, and Cochrane Library, from inception to August 2025, following PRISMA guidelines and registered with the International Prospective Register of Systematic Reviews (PROSPERO). Statistical analyses were performed using a random-effects model. Results: The initial search yielded 1236 studies; 6 studies with 413 pediatric patients met the inclusion criteria. A total of 163 underwent short leg casting (SLC) and 250 long leg casting (LLC). No differences were observed between SLC and LLC for coronal angulation (MD=0.12 degrees, 95% CI=−0.89 to 1.12, I 2 =58%) or sagittal angulation (MD=0.18 degrees, 95% CI=−0.71 to 1.07, I 2 =56%). Subgroup analyses showed no differences for tibial shaft fractures or Salter-Harris distal tibial fractures. Cast duration was similar between groups (MD=−0.74 wk, 95% CI=−1.49 to 0.01, I 2 =92%). Overall complication rates did not differ (OR=0.76, 95% CI=0.25 to 2.34, I 2 =0%), with no differences in Salter-Harris subgroup analysis (OR=0.67, 95% CI=0.05 to 9.91; I 2 =54%). SLC was associated with shorter time to weight-bearing (MD=−2.29, 95% CI=−4.49 to −0.08, I 2 =68%) and faster time to union (MD=−1.21, 95% CI=−2.16 to −0.25, I 2 =30%). Conclusion: SLCs may be considered as an alternative to LLCs in pediatric tibial shaft and distal tibial physeal fractures based on currently available retrospective comparative evidence. However, the evidence is limited by the retrospective design, clinical heterogeneity, and risk of confounding. Further prospective comparative studies are needed to define optimal indications for SLC use in this population. Level of Evidence: Level III, systematic review and meta-analysis of retrospective comparative studies.

Importance A greater proportion of older patients (age ≥65 years) are undergoing thyroidectomy amidst an aging population. Given the elusive results in the literature, clarifying whether older patients face different thyroidectomy safety profiles is crucial for optimizing risk assessment and patient counseling. Objective To evaluate the association between older age (age ≥65 years) and thyroidectomy safety by comparing endocrine-related complications, including recurrent laryngeal nerve injury, hypocalcemia, hematoma, and mortality in older compared with younger patients. Data Sources Ovid MEDLINE, CINAHL, Ovid Embase, and the Cochrane Library were systematically searched from inception to May 29, 2025; only English-language studies were included. Study Selection Cohort studies comparing thyroidectomy outcomes between older and younger patients and reporting endocrine-related complications were included. Two independent reviewers screened abstracts and full texts. Of 3192 studies identified, 11 met inclusion criteria. Data Extraction and Synthesis Two independent reviewers extracted data following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Risk of bias across studies was evaluated using the ROBINS-I (Risk of Bias in Nonrandomized Studies of Interventions) tool. Random-effects models were used to pool data. Main Outcomes and Measures Incidence of recurrent laryngeal nerve injury, hypocalcemia, and hematoma; odds ratios (ORs) with 95% CIs were calculated. Results The analysis included 11 studies with a total of 427 886 patients of whom 104 232 (24.4%) were older adults (≥65 years). Older adults had greater odds of overall recurrent laryngeal nerve injury (2.3% vs 1.0%; OR, 1.58; 95% CI, 1.15-2.16; I 2 = 76%), hematoma (2.4% vs 1.0%; OR, 2.32; 95% CI, 1.70-3.16; I 2 = 0%), and mortality at last follow-up (0.3% vs 0.01%; OR, 11.09; 95% CI, 1.77-69.52; I 2 = 90%) compared with younger patients. However, rates of overall hypocalcemia (OR, 0.80; 95% CI, 0.61-1.05; I 2 = 71%) and wound complications (OR, 1.38; 95% CI, 0.92-2.06; I 2 = 0%) were similar. Conclusions and Relevance This systematic review and meta-analysis found that thyroidectomy is safe in older patients, with only small absolute increases in recurrent laryngeal nerve injury, hematoma, and mortality despite statistical significance. These findings support individualized counseling and perioperative planning while acknowledging the overall safety of thyroidectomy in this population.

Objective To evaluate the safety and efficacy of Grayson's presurgical nasoalveolar molding (PNAM) technique on nasal and alveolar morphology in infants with unilateral cleft lip and palate (UCLP). Design Systematic review and meta-analysis. Setting : Multicenter international literature across clinical and academic institutions. Patients, Participants Infants with UCLP reported in 21 eligible studies (n = 534), of whom 368 received PNAM. Interventions Presurgical nasoalveolar molding (PNAM) according to the Grayson protocol. Main Outcome Measure(s) : Changes in nasal symmetry (nostril width ratio, columellar angle) and alveolar morphology (alveolar gap dimensions, intertuberosity distance). Results PNAM was performed for an average duration of 96 days with 11 adjustments per patient. Pooled analyses demonstrated significant improvements in nasal symmetry: nostril width ratio decreased from 2.4 (95% CI, 1.7–3.1; I² = 98%) to 1.8 (95% CI, 0.9–2.6; I² = 97%), and the columellar angle increased from 52° (95% CI, 42.0–62.8; I² = 100%) to 70° (95% CI, 59.1–80.6; I² = 98%). Alveolar gap narrowed from 10.7 mm (95% CI, 9.5–11.9; I² = 92%) to 3.9 mm (95% CI, 3.1–4.8; I² = 93%). Intertuberosity distance increased slightly, from 31.3 mm (95% CI, 29.3–33.3; I² = 95%) to 31.8 mm (95% CI, 28.9–34.8; I² = 98%). Conclusions Grayson's PNAM appears to improve nasal and alveolar morphology in infants with UCLP prior to definitive surgery. Standardized outcome measures and long-term prospective studies are needed to confirm these findings and refine clinical protocols.

Silver foam dressings have been extensively used in the management of burn injuries; however, its application in children requires elucidation. A literature search was conducted from database inception to October 2023. Eligible studies reported paediatrics patients under 21 years of age receiving silver dressings for burns or scalds. This review was registered prospectively with PROSPERO (CRD42023470239). 18 studies met the inclusion criteria with a total of 701 patients. The pooled mean time to re-epithelisation (TTRE) was 12.9 days (95% CI: 11.2, 14.6, I2 = 94%). The pooled mean duration of hospitalisation was 9.8 days (95% CI: 3.9, 15.7; I2 = 100%). Mean number of total dressing changes per patient was 3.6 (95% CI: 2.2, 4.9; I2 = 99%). There were a total of 98 complications, including 30 (30.6%) infections, 29 (29.6%) surgical requirements, 14 (14.3%) hypertrophic scarring, 17 (17.3%) escalations of care, 5 (5.1%) burn depth progression, and 3 (3.1%) others. Silver foam dressings appear as a safe and effective approach in terms of healing rate and dressing change frequency for selected paediatric patients with burn injuries. Despite the promising results, further comparative studies are required to evaluate the selection criteria and long-term effect of silver foam dressing.
