Background: Vascular injuries in simple close fractures are rare and low suspicion risk for primary surgeons. They include thrombus formation, hematomas, pseudoaneurysms, ischemic changes, and absent pulsations. These injuries can cause morbid sequelae, including compartment syndrome, reperfusion injury, exsanguination, and limb loss. Case presentation: Following a closed femoral shaft fracture, a 12-year-old boy came to us with a compromised superficial femoral artery (SFA). At the moment of fixing, there was no evidence of arterial involvement. He presented to the Out-patient Department (OPD) two weeks after the primary surgery with swelling at the fracture site. CT-Angiography was performed, and the swelling was diagnosed as a pseudoaneurysm of the superficial femoral artery, which was repaired using a Great Saphenous Vein (GSV) graft. Conclusion: These uncommon vascular injuries in closed fractures can be identified by a thorough clinical examination and specific diagnostic tests, and with prompt vascular repair, limb-threatening consequences are preventable. In a simple close femur fracture without suspicious signs in clinical findings, it's not a routine practice to check the vascular status by means of fancy and costly diagnostic tests.

This review article provides a comprehensive overview of the multidisciplinary management of giant cell tumors of the bone (GCTB). GCTB is a rare, intermediate-grade, benign, locally aggressive osteolytic neoplasm that primarily affects the epiphyses of long bones in individuals aged 20–45, with a female predominance. The article discusses the epidemiology, clinical features, and various management approaches for GCTB.The article highlights the importance of GCTB, which can resemble other bone lesions, so an accurate diagnosis is essential. A biopsy is a definitive way to diagnose GCTB. While, radiography includes MRI, PET scans, and bone scans to help diagnose and stage GCTB. The Campanacci grading system, based on radiographic appearance and soft tissue involvement, is commonly used to stage GCTB.Surgical management options for GCTB include intralesional curettage, wide marginal resection, and en-bloc resection, depending on the location and extent of the tumor. In challenging anatomical locations, such as the axial skeleton, intralesional curettage may be the only viable option to preserve function and minimize surgical morbidity. However, it is associated with a high rate of local recurrence. Wide marginal resection is effective in reducing recurrence rates but may result in significant morbidity and require bone defect reconstruction. En-bloc resection is preferred for tumors with soft tissue extension or involvement of expendable bones.In cases where complete surgical resection is not feasible or carries a high risk of morbidity, alternative treatment options such as radiation therapy, arterial embolization, and systemic therapy with bisphosphonates (zoledronic acid) and denosumab are valuable tools in achieving disease control and improving patient outcomes. Radiotherapy is employed for cases where the disease has recurred locally and cannot be removed surgically. Arterial embolization involves interrupting the blood supply to tumors in areas that cannot be operated on. Bisphosphonates are drugs that can be given before or after surgery to reduce the chances of recurrence by inhibiting osteoclast activity.Denosumab, a monoclonal antibody that targets RANKL, has shown promising results in reducing tumor size, facilitating surgical treatment, and improving outcomes. In conclusion, this review provides valuable insights into the epidemiology, clinical features, and multidisciplinary management approaches for GCTB. Accurate diagnosis, appropriate staging, and individualized treatment strategies are essential for optimizing patient outcomes in GCTB management.

Industrial wastewater effluent containing dyes and hazardous waste, such as olive waste, pose serious threat to health and environment. This work investigated the removal of azo and non-azo dyes from a single and binary aqueous system using hydrochar produced from hazardous olive waste using hydrothermal carbonization (HTC). Optimisation suggested hydrochar obtained at 250°C (HC-9) exhibited best physiochemical, structural properties and around 300% increase in carboxylic and carbonyl groups indicated by nuclear magnetic resonance spectroscopy. HC-9 removed ∼100% of Methylene blue and Congo red in single (120 and 180 min) and binary system (60 min), respectively. Ex situ X-ray photon electron spectroscopy and surface area analysis after adsorption suggested chemisorption supported by pseudo-second order reaction, Langmuir, and Redlich-Peterson model. HC-9 exhibited around 80% reusability in three adsorption cycles. Thus, better working efficiency of our hydrochar in the complex wastewater make it a potential candidate to be employed in commercial plants.

The synthesis methodology, particle size and shape, dose optimization, and toxicity studies of nano-fertilizers are vital prior to their field application. This study investigates the comparative response of chemically synthesized and biologically synthesized iron oxide nanorods (NRs) using moringa olefera along with bulk FeCl3 on summer maize (Zea mays). It is found that FeCl3 salt and chemically synthesized iron oxides NRs caused growth retardation and impaired plant physiological and anti-oxidative activities at a concentration higher than 25 mg/L due to toxicity by over accumulation. While iron released form biologically synthesized NRs have shown significantly positive results even at 50 mg/L due to their low toxicity, an improved leaf area (13%), number of leaves per plant (26%), total chlorophyll content (80%) and nitrate content (6%) with biologically synthesized NRs are obtained. Moreover, the plant anti-oxidative activity also increased on treatment with biologically synthesized NRs because of their ability to form a complex with metal ions. These findings suggest that biologically synthesized iron oxides NRs are an efficient iron source and can last for a long time. Thus, proving that nanofertilizer are required to have specific surface chemistry to release the nutrient in an appropriate concentration for better plant growth.

Purpose: This study aims to evaluate the adherence of orthopedic surgeons towards the BOAST and Rehabilitation guidelines for the diagnostic, surgical, and rehabilitation in the management of ACL injury. Methods: The clinical audit included 82 patients who had ACL reconstruction from August 1, 2018 to October 31, 2023. The retrospective data was collected for the clinical assessment, MRI timing, meniscus repair considerations, graft selection, and adherence to the rehabilitation guidelines to assess the adherence to the ACL reconstruction protocol provided by the BOAST and rehabilitation guidelines. Results: Prompt clinical assessments were observed, however, variability in MRI timings indicates concerns in the standard protocol. Meniscal repair considerations were present in 70.73 % of cases. Patient involvement in graft selection discussions favored the quadruple hamstring graft. Positive early-phase outcomes in Rehabilitation Protocol were noted, but non-compliance in later stages poses a significant challenge. Conclusion: The results showed adherence towards diagnostics methods, surgical interventions, and early rehabilitation, however, patient non-compliance after phase I was a major concern and requires special attention to addressing factors like patient education and socioeconomic barriers is crucial for comprehensive care.
