Successful deformity correction depends on establishing the aetiology of the deformity. Clinical examination, additional laboratory tests and consultation with other experts may be needed to complete the workup. Imaging studies should include full-length standing X-rays in all relevant planes, and additional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) may add information on bone morphology and growth plates' anatomy. Based on the data, analysis of the deformity and length differences is performed, followed by prediction of deformities at skeletal maturity...

BACKGROUND: The role of perioperative erythropoietin (EPO) for preventing cardiac surgery associated acute kidney injury (CSA-AKI) remains uncertain with published trials producing conflicting results. Perspective into the factors at work is needed, due to ongoing uncertainty. METHODS: We undertook the systematic review and meta-analysis of randomised-controlled trials (RCTs) using random-effects modelling. The primary outcome was safety and efficacy of perioperative EPO to prevent CSA-AKI and the secondary outcomes were change in serum creatinine, urinary neutrophil gelatinase-associated lipocalin, time in ICU, rates of postoperative transfusions, haemodialysis, and mortality...

INTRODUCTION: Because allogeneic blood transfusion carries a risk of serious complications, erythropoietin (EPO) has been used in patients scheduled for total hip or knee arthroplasty in an effort to reduce the need for allogeneic blood transfusion; however, its efficacy, cost-effectiveness, and safety are still controversial. The purpose of this review was to determine the hematopoiesis-promoting effect and potential complications, as well as the cost-effectiveness, of preoperative use of EPO in patients scheduled for total hip or knee arthroplasty...

BACKGROUND: The increasing incidence of osteoporotic hip fracture (HF) has raised the requirements of red blood cell (RBC) transfusions, whereas this scarce resource may cause morbidity and mortality. STUDY DESIGN AND METHODS: This study was a multicenter, randomized, double-blind, clinical trial that aimed to assess efficacy of ferric carboxymaltose (FCM) with or without erythropoietin (EPO) in reducing RBC transfusion in the perioperative period of HF. Participants (patients > 65 years admitted with HF and hemoglobin [Hb] levels of 90-120 g/L) were randomly assigned to receive a preoperative single dose of 1 g of FCM (short intravenous [IV] infusion over 15 min), plus 40,000 IU of subcutaneous EPO (EPOFE arm); versus 1 g of IV FCM plus subcutaneous placebo (FE arm); and versus IV and subcutaneous placebo (placebo arm)...

BACKGROUND To explore the use of hepcidin as a marker of impaired renal function in a rat model for chronic allograft nephropathy (CAN). MATERIAL AND METHODS Twenty-four models were developed and 20 models were included in this study, using Fisher (F344) rats (donors) and Lewis rats (recipients). Renal function tests were performed preoperatively and postoperatively. Hepcidin, interleukin-6 (IL-6), and erythropoietin levels in serum and urine were measured by enzyme-linked immunosorbent assay (ELISA). To observe pathological changes in the kidneys, 10 rats each were sacrificed at 2 months and 4 months after surgery...

BACKGROUND: Patient blood management (PBM) must be promoted in orthopedic surgery and relies on different strategies implemented during the entire perioperative period. Our aim was to assess whether the introduction of a pre-, intra-, and postoperative PBM protocol combining erythropoietin (EPO), ferric carboxymaltose (FCM), and tranexamic acid was effective in reducing perioperative transfusion and postoperative anemia. STUDY DESIGN AND METHODS: In a two-phase prospective observational study, all patients admitted for total hip or knee arthroplasty were included the day before surgery...

BACKGROUND: Preoperative anemia is present in 20% of total joint arthroplasty patients. Current preoperative treatment options, including iron supplementation (FE) and erythropoietin (EPO), are expensive. Tranexamic acid (TXA) has been adopted as an intraoperative adjunct to decrease blood loss. Our hypothesis is that TXA is a cost-effective treatment compared to FE and EPO in anemic patients. METHODS: In this study, a cost analysis was performed, comparing the material costs of TXA and packed red blood cells (PRBCs) to the theoretical administration and material costs of FE and EPO per standard preoperative anemia protocol...

Endoscopic sinus surgery (ESS) for patients with severe chronic rhinosinusitis (CRS) has become a well-established treatment in cases where medical therapy fails. Even though CRS patients are divided into two subgroups, CRS with nasal polyposis (CRSwNP) and CRS without nasal polyposis (CRSsNP), most studies present only results for the total cohort. This prospective cohort study evaluated the efficacy of ESS on both quality of life and olfactory function measures, in a cohort of Danish CRS patients diagnosed according to the EPOS criteria, with results analysed separately for the CRSwNP and CRSsNP subgroups...

BACKGROUND: Neurosurgery may involve significant blood loss and frequently requires allogeneic red blood cell (RBC) transfusion. Preoperative recombinant erythropoietin (EPO) may be used to improve erythroid status and recovery, and used either alone or in combination with preoperative autologous donation (PAD) it may reduce exposure to allogeneic RBC. We wished to study the use of EPO with and without PAD and the risk of RBC transfusion in neurosurgery. METHODS: Using a retrospective case-control design, 57 patients who received EPO preoperatively were matched 2:1 for age, sex, year of surgery, and International Classification of Diseases code most responsible for surgery (three were excluded because of stringent matching criteria, leaving 54 cases and 108 comparison subjects)...
