We assessed the radiological and functional results of pediatric both-bone forearm diaphyseal fractures treated using elastic stable intramedullary nails (ESINs), as well as factors affecting the results. In total, 36 patients (33 males and three females; mean age, 11.6 years) were included. The mean follow-up time was 41.5 (18-96) months. Patient demographic characteristics and the details of the surgical techniques were analyzed retrospectively. In addition to standard radiographic evaluations, the ratio between the nail diameter and medullary canal diameter (ND/MCD) was measured, as well as the maximal radial bowing. According to the criteria of Price and Flynn, 28 (77.8%) and eight (22.2%) patients had excellent and good results, respectively. There were no cases of nonunion or delayed union. There was no significant difference in functional or radiological results according to whether titanium nails (24 patients) or stainless steel nails (12 patients) were used (all P  > 0.05). Nail prebending (performed in 19 patients) did not affect the functional or radiological results ( P  > 0.05). Loss of reduction was observed in four patients with an ND/MCD ratio <40%. The maximal radial bowing improved in all patients. The mean change was significantly greater in patients with diastases and 22D/4.1 fractures. Regardless of nail type or prebending status, surgery using ESIN placement effectively treats both-bone forearm diaphyseal fractures; radial bow remodeling outcomes are excellent. We recommend that the ND/MCD ratio should be 40-70%., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Objective: This study aimed to compare the clinical and radiological findings of radical reduction (open reduction and Salter innominate osteotomy combined with femoral osteotomy) for children of walking age, younger and older than 4 years in the treatment of with developmental dysplasia of the hip (DDH)., Methods: In this retrospective study, children of walking age with DDH who underwent radical reduction between 2008 and 2014 were identified. They were then divided into 2 groups according to the age at which the surgery was performed: before and after the age of 4 years. Improvement in the acetabular index was examined on follow-up radiographs. The presence of avascular necrosis (AVN) was determined and classified on the basis of the Kalamchi-MacEwen classification on final follow-up radiographs. Clinical assessment was performed with the modified McKay criteria at the final follow-up appointment., Results: A total of 19 children (14 girls, 5 boys; mean age=37.5±21 months) (25 hips) were included. Their mean age was 27.9±4.9 and 63.3±19.7 months in children operated before and after the age of 4 years, respectively. The mean follow-up time was 29.9±19 and 19.6±5 months in children operated before and after the age of 4 years, respectively. No significant difference was observed in improvements in the acetabular index between children younger than 4 years (24±6.9°) and those older than 4 years (20.7±6.7°) (p=0.25). According to the modified McKay criteria, all the children younger than 4 years exhibited excellent or good clinical results compared with those operated after the age of 4 years (67%) (p=0.013). At the final follow-up, 64% of all patients demonstrated no radiographical sign of AVN. The rates of AVN were significantly higher in children operated after the age of 4 years (33%) than in those operated before the age of 4 years (19%) (p=0.049)., Conclusion: Better clinical and radiographical results can be expected from radical reduction in children undergoing surgery before the age of 4 years., Level of Evidence: level III, Therapeutic Study.

BACKGROUND The aim of this retrospective study was to compare the measurements of bone mineral density (BMD) combined with volumetric dental tomography measurements taken from three main regions selected on the lower mandible, the right mandibular, medial mandibular, and left mandibular regions, in patients with ectodermal dysplasia and age-matched and gender-matched controls. Measurement of BMD in Hounsfield units (HUs) were evaluated using three-dimensional (3D) cone beam computed tomography (CBCT) imaging. MATERIAL AND METHODS Mandibular bone tomography images were evaluated from 9 women and 5 men diagnosed with ectodermal dysplasia and a control group of 9 women and 5 men. The HU values obtained according to age and gender of the total 28 study participants were measured. Statistical analysis of the data used Student's t-test. RESULTS BMD in the ectodermal dysplasia group was significantly lower compared with the BMD in the control group. Comparison of the left and right mandibular angulus regions showed that the BMD of patients with ectodermal dysplasia was significantly lower when compared with the control group in both regions, but no significant difference was found between the two groups in the BMD of the central mandibular region. CBCT was found to be an effective method for the measurement of BMD. CONCLUSIONS In patients with ectodermal dysplasia, reduced BMD should be taken into consideration when planning surgical interventions involving bone tissue and when planning implant surgery. The results of this study may be of value in dentistry and other fields of medicine.

Background: Children have a curiosity for climbing walls, stairs, and railings and have an increased risk of falling. Here, we report our experience with railings causing injuries by penetrating the upper extremities, and aim to call attention to spiked railing injuries in children., Methods: We report on five children with a mean age of 8.8. All of the children were male. The penetrating railing parts were removed in a surgical room., Results: The injured structures repaired immediately were as follows: flexor digitorum profundus tendon, A4 pulley, volar plate of the distal interphalangeal joint, radial digital nerve, ulnar digital artery, and radial digital artery., Conclusion: Spiked railings can lead to significant injury that requires further exploration. Boys particularly are at risk, and parents should be alert regarding these type of injuries. We recommend a standard regulation for fence erection, and we wish to warn owners of this type of fence regarding probable legal sanctions.

Objectives: This study aims to investigate the role of KRAS/BRAF gene mutation in the pathogenesis of oropharyngeal squamous cell carcinoma (OSCC)., Patients and Methods: A total of 26 OSCC patients (23 males, 3 females; mean age 60 years; range 41 to 77 years) diagnosed between January 2003 and November 2013 were included in the study. The methods used in our study were quantitative fluorescence polymerase chain reaction for KRAS/BRAF mutation analysis., Results: Ten of the tumors were located at the tongue base, 12 in the tonsil and four at the floor of mouth. The mean tumor size was 3.8 cm. Six of the tumors were well differentiated, 18 were moderately differentiated and two were poorly differentiated. All cases were analyzed for KRAS and BRAF gene mutations and none of them showed gene mutations., Conclusion: We could not find any relation between OSCC and KRAS/BRAF gene mutations in our short case file. The role of mutations should be analyzed in larger series in OSCC to predict new targeted therapy modalities.

This report describes a mitral valvular cyst mimicking a solid mass in an 80-year-old patient. The diagnosis was based on histopathological evaluation of the resected material. This report emphasizes the possibility of misdiagnosis by echocardiographic and other imaging modalities of a mitral valvular mass in a patient without any clinical signs and symptoms.
