Osteochondromas are neoplasm that belong to the family of cartilaginous histogenesis tumors and represent 90% of all forms of exostoses. As most osteochondromas are asymptomatic, underdiagnosis is frequent. Symptomatic forms usually manifest before the age of 20 years, and the most common symptoms are pain and the detection of a bony mass. Herein, we report four cases of spontaneous regression of solitary osteochondromas in the light of literature. We consider that orthopedic surgeons should take into account the possibility of spontaneous regression of these tumors, before recommending surgery. Symptoms are usually mild and we recommend following these patients with X-ray and physical examination annually.
Background: Antibiotic resistance has become a growing global problem where overprescription is a contributing factor for its development. In the endodontics field, complementary treatments, such as antimicrobial photodynamic therapy (aPDT), have been described to eliminate residual bacteria from the root canal space and reduce complications. The aim of this review is to describe the literature evidence up to now regarding the advantages, efficiency, and clinical outcomes of this therapy in endodontics as a possible tool to combat antibiotic resistance. Methods: A review of the literature from 2010 to 2021 was carried out using the PubMed and Web of Science databases. Two steps were taken: First, articles were compiled through the terms and MeSH terms “Photochesdmotherapy” and “endodontics.” Then, a second search was conducted using “photodynamic therapy” and “antibiotic resistance” or “drug resistance, microbial.” Results: A total of 51 articles were included for evaluation: 27 laboratory studies, 14 reviews, and 10 clinical studies. Laboratory studies show that aPDT achieves significant bacterial elimination, even against antibiotic-resistant species, and is also effective in biofilm disruption. Clinical studies suggest that aPDT can be considered a promising technique to reduce bacterial complications, and reviews about the issue confirm its advantages. Conclusion: The benefits of aPDT in reducing complications due to its antibacterial effects means a possible decrease in systemic antibiotic prescription in endodontics. In addition, it could be an alternative to local intracanal antibiotic therapy, avoiding the appearance of possible antibiotic resistance, as no bacterial resistance with aPDT has been described to date.
Objectives This study reports the surgical outcomes in a patient cohort with congenital pseudarthrosis of the clavicle (CPC). Patients and methods A total of nine pediatric patients (5 males, 4 females; mean age: 4.43 years; range, 2 to 12 years) who were diagnosed with CPC and treated surgically with a minimum one-year follow-up between January 1996 and December 2018 were retrospectively analyzed. The patients were divided into two groups according to the fixation method as the Kirschner wire (K-wire; Group A, n=2) or stabilization with a plate (Group B, n=7). The physical function and symptoms were evaluated using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scale. Results The mean age at the time of diagnosis was 2.95 (range, 0 to 12) years. Six cases were atrophic pseudarthrosis and three cases were hypertrophic. Radiographic consolidation occurred in all cases with a mean duration of 103.8±39.1 days, indicating no significant difference between the groups (p>0.05). Complications registered were a K-wire breakage in a patient in Group A and an internal fixation plate loosening in a patient in Group B. The mean postoperative follow-up was 2.98±1.82 years. The QuickDASH score was 0 points in all patients. Conclusion The early surgical indication based on refreshment of the pseudarthrosis focus, with bone autograft interposition when a failure exists to restore adequate clavicular length, and fixation are reliable alternatives with favorable clinical and radiological results in the mid- and long-term with fewer complications.
Objectives This study aims to analyze the functional results, management, and complications of acute Seymour fracture treatment and to generalize the understanding of Seymour fractures, as well as awareness about its controversial treatment and critical sequelae. Patients and methods Between January 1994 and December 2019, a total of 29 patients (20 males, 9 females; mean age: 7.9±3.9 years; range, 1 to 15 years) who presented within the first 24 h of injury and were diagnosed with Seymour fractures and treated in the emergency setting were retrospectively analyzed. Clinical and radiological data were collected from medical records at the time of diagnosis and during follow-up, within a week after the treatment and in the visits required until fracture healing, and no sequelae were observed. In the event of complications, a minimum of one year of follow-up was carried out. Radiographs were taken of the anteroposterior and lateral views during each visit. Results The mean follow-up was 10.8±8.6 (range, 2 to 36) months. Surgical treatment in the operating room was performed in 24 (82.7%) patients using a single longitudinal Kirschner wire (K-wire) fixation through the distal phalanx and the distal interphalangeal joint in 21 patients. Non-operative treatment based on closed reduction and splinting was performed in five (17.3%) patients. There was no statistically significant difference in the final passive range of motion and physeal growth arrest in relation to the use or non-use of K-wires. The use of antibiotics in any of the three possible administrations (intravenous antibiotic regimen, intravenous and later oral antibiotic at-home or oral antibiotics), in relation to the non-use of antibiotics seemed to be a protective factor against infections (odds ratio=0.04; 95% confidence interval: 0.006-0.2; p=0.001). Conclusion The identification of Seymour fractures is crucial for applying the correct treatment and reducing the risk of complications, such as osteomyelitis and physeal alterations. Based on our study results, we can suggest that the use of an antibiotic regimen causes a lower risk of infections in acute Seymour fractures. The prompt identification of these fractures with a standardized protocol covering irrigation, debridement, reduction, fixation, and prophylactic antibiotics is needed to avoid complications.
