Do Nonsteroidal Anti-Inflammatory Drugs Affect Bone Healing? A Critical Analysis
Nonsteroidal anti-inflammatory drugs (NSAIDs) play an essential part in our approach to control pain in the posttraumatic setting. Over the last decades, several studies suggested that NSAIDs interfere with bone healing while others contradict these findings. Although their analgesic potency is well proven, clinicians remain puzzled over the potential safety issues. We have systematically reviewed the available literature, analyzing and presenting the available in vitro animal and clinical studies on this field. Our comprehensive review reveals the great diversity of the presented data in all groups of studies. Animal and in vitro studies present so conflicting data that even studies with identical parameters have opposing results. Basic science research defining the exact mechanism with which NSAIDs could interfere with bone cells and also the conduction of well-randomized prospective clinical trials are warranted. In the absence of robust clinical or scientific evidence, clinicians should treat NSAIDs as a risk factor for bone healing impairment, and their administration should be avoided in high-risk patients
Deep Vein Thrombosis and Pulmonary Embolism in a Child with Diabetic Ketoacidosis and Protein S Deficiency: A Case Report
Introduction: Diabetic ketoacidosis (DKA) is considered a
hypercoagulable state, which may be exacerbated in patients with
thrombophilia and lead to thrombosis. Case Report: We report on a
5.5-year-old boy, who was admitted to the pediatric department with DKA
due to newly diagnosed type 1 diabetes. Low-grade fever was reported for
6 days prior to admission and continued during DKA management, with
negative septic screening. After DKA management, the child developed
symptoms of iliofemoral deep vein thrombosis (DVT). A family history of
protein S (PS) deficiency was revealed. He was initially treated
intravenously with antibiotics and unfractionated heparin, which, after
2 days, was switched to low-molecular-weight heparin and vitamin K
antagonist (VKA) due to poor anticoagulant response. On the 6th day of
anticoagulant treatment, the patient presented with pulmonary embolism
(PE); he continued with VKA and antibiotics, with significant clinical
improvement. Prolonged fever was attributed to DVT and PE. The patient
was discharged on oral anticoagulants and insulin. Conclusion: We report
on a child with congenital PS deficiency and DKA who developed DVT and
PE despite anticoagulant treatment. It is important in children
presenting with DKA to seek thoroughly for a medical history of
thrombophilia and to start early thromboprophylaxis in such cases in
order to prevent a possible thrombosis. Copyright (C) 2013 S. Karger AG,

Serum Hepcidin and Ferritin to Iron Ratio in Evaluation of Bacterial Versus Viral Infections in Children A Single-center Study
Background: Differential diagnosis of childhood infections is important.
Several biochemical indices steer diagnosis toward bacterial agents,
although the data are often not definitive. Hepcidin is a central
component of blood iron, and ferritin alterations occur during
infections. We measured hepcidin changes and evaluated ferritin to iron
ratio (FIR) in patients with suspected infections.
Methods: We studied 69 children with infection and an equal number of
matched controls during a 3-year period. A bacterial agent was
demonstrated in 17 and a viral pathogen in 52 of the patients.
Hematologic and biochemical tests were performed on all children
including ferritin, iron and hepcidin. FIR was calculated and receiver
operating characteristic curve analysis was performed to evaluate the
best FIR cutoff value to discriminate between patients and controls and
between patients with bacterial infections and viral infections.
Results: Hepcidin, ferritin and FIR were significantly higher and iron
values significantly lower in febrile patients than its controls.
Patients with bacterial infection had significantly lower iron and
higher FIR than those with viral infection. FIR had high accuracy
discriminating patients from controls but only moderate accuracy
discriminating bacterial from viral infected patients.
Conclusions: If further studies with larger samples confirm these
observations, FIR could be used as an inexpensive, rapid and easily
performed complementary index for diagnosis of bacterial infections
Release of growth factors and the effect of age, sex, and severity of injury after long bone fracture
Efficacy of minimally invasive techniques for enhancement of fracture healing: evidence today
The successful treatment of nonunions represents a major challenge for orthopaedic surgeons. Lately, ongoing advances made in the field of molecular medicine and molecular biology have increased our understanding of the pathways and involvement of mediators surrounding the bone healing process. As a result, the surgeon’s armamentarium has been increased in terms of options for intervention. This article aims to provide an overview of minimally invasive techniques applicable in the treatment of nonunions of fractures
