Abstract Introduction: Lumpectomy is a standard breast-conserving procedure, yet acute postoperative complications may delay recovery and adjuvant treatment. Beyond clinical risk factors, tumor biology may influence wound healing and inflammatory responses. This study aimed to evaluate the association between progesterone receptor expression and the incidence of acute postoperative complications following lumpectomy.

Material and methods: This descriptive cross-sectional study was conducted at Tabriz University of Medical Sciences in 2025 on 54 women undergoing lumpectomy, with sample size estimated using the Cochran formula and participants enrolled by convenience sampling. Progesterone receptor expression was assessed by immunohistochemistry on surgical specimens, and its association with acute postoperative complications was analyzed alongside demographic, clinical, pathological, and perioperative variables using appropriate statistical tests.

Results: Results summary: Among 54 patients undergoing lumpectomy, PR-negative status was associated with poorer early postoperative outcomes. Compared with PR-positive patients, PR-negative patients had higher postoperative VAS scores (4.06 ± 1.43 vs. 3.14 ± 1.21; p = 0.017), more acute complications (50.00% vs. 22.22%; p = 0.037), and more unplanned visits (33.33% vs. 11.11%; p = 0.048). PR negativity independently predicted complications after adjustment (OR = 3.84; p = 0.039).

Conclusion: PR-negative status was associated with a higher risk of acute postoperative complications after lumpectomy. Despite broadly comparable operative variables, PR-negative patients experienced greater postoperative morbidity and more unplanned visits, suggesting that receptor status may help identify patients requiring closer early postoperative monitoring.

Abstract Introduction: Nasal bone fracture is a common facial injury with potential early postoperative consequences, including pain, bleeding, edema, airway symptoms, and residual deformity. Fracture severity may influence these outcomes by reflecting the extent of structural and soft-tissue damage. This study aimed to determine short-term postoperative complications according to nasal bone fracture severity.

Material and methods: This descriptive cross-sectional study of 75 patients at Tabriz University of Medical Sciences in 2024 investigated the association between nasal bone fracture severity and early outcomes. Measured variables included demographics, fracture characteristics, surgical parameters, and short-term complications, including VAS pain score, epistaxis, edema, ecchymosis, and septal hematoma. Data were analyzed using normality testing, t-tests, Mann-Whitney U, and chi-square tests.

Results: Among 75 patients, severe/complex nasal fractures (n = 34) were associated with worse short-term postoperative outcomes than mild/moderate injuries (n = 41). Severe fracture patients experienced longer operations (41.53 ± 11.47 vs. 28.64 ± 8.12 minutes, p < 0.001), higher 24-hour VAS pain (4.85 ± 1.56 vs. 3.42 ± 1.18, p < 0.001), increased moderate/severe edema (61.76% vs. 26.83%, p = 0.002), and more unplanned visits (26.47% vs. 7.32%, p = 0.027). Severe fracture independently predicted early complications (adjusted OR = 3.86, p = 0.020).

Conclusion: Severe nasal bone fractures are independently associated with an increased risk of short-term postoperative complications. Patients with complex fracture patterns experience higher pain levels, more pronounced soft-tissue edema, and greater rates of early residual deformity, leading to more frequent unplanned clinical evaluations. Preoperative severity stratification can identify high-risk cases requiring closer early postoperative surveillance.

Abstract Introduction: Tibial fractures present substantial healing challenges because limited soft-tissue coverage, vulnerable blood supply, fracture complexity, and host-related factors increase the risk of impaired union. Although plate fixation restores alignment and stability, it may contribute to infection, nonunion, malunion, and implant-related complications. This study aimed to evaluate healing time and complications following tibial fracture plating from a pathologic perspective.

Material and methods: This descriptive cross-sectional study included 52 patients who underwent plate fixation for tibial fractures at Shahid Madani Hospital, Tabriz, selected through convenience sampling. Demographic, clinical, fracture-related, laboratory, operative, and postoperative data were collected from medical records and follow-up assessments. Healing time was determined using clinical and radiographic evidence of union, while postoperative complications, including infection, impaired union, malalignment, and implant-related failure, were documented.

Results: Patients with postoperative complications were older and had more severe injuries, including higher rates of open and comminuted fractures, longer time to surgery, and worse preoperative inflammatory and nutritional profiles (all significant variables, P<0.05). Healing time was markedly prolonged in complicated cases (23.2 ± 4.6 vs 15.9 ± 3.2 weeks, P<0.001). Independent predictors included age (OR=1.04), open fracture (OR=2.86), CRP (OR=1.17), surgical delay (OR=1.38), and operative duration (OR=1.21).

Conclusion: These findings indicate that postoperative complications after tibial plate fixation are driven by both fracture severity and adverse preoperative biological status. Early surgical management, control of inflammation, and optimization of hemoglobin and albumin levels may improve healing and reduce complication risk. Preoperative CRP and operative burden appear particularly valuable for risk stratification and perioperative decision-making.
