OBJECTIVES: To analyze the diagnostic accuracy of conventional and digital radiographic images and the impact of digital filters in evaluating the bone/implant interface. METHODS: Titanium implants were inserted into 74 fresh bovine ribs blocks, 37 fitting tight to the bone walls (simulating the existence of osseointegration), and 37 with a gap of 0.125 mm (simulating a failure in the osseointegration process). Periapical radiographs were taken with conventional film and two phosphor-plate systems (Vista Scan and Express)...

Osteosarcoma (OS) involving the head and neck region is rare and is a diagnostic challenge due to its aggressive nature and varied presentations. Although OS constitute 40% to 60% of all bone tumours, only 10% of these occur in the head and neck region, most commonly in the maxilla and mandible. OS of the jaw bone has a different pattern and behaviour when compared to OS at other anatomic location. It occurs in a more elderly population, less aggressive and usually spreads locally rather than distant metastases...

AIM: We have previously shown that the secreted glycoprotein MFG-E8 has anti-inflammatory and anti-osteoclastogenic properties. Our objective was to investigate the potential of MFG-E8 as a diagnostic or therapeutic agent in periodontitis. MATERIALS AND METHODS: Periodontitis was induced in non-human primates (NHPs) by placing ligatures around posterior teeth on both halves of the mandible for a split-mouth design: one side was treated with MFG-E8-Fc and the other with Fc control...

Though the variations of vertebral artery are clinically asymptomatic yet abnormalities are of diagnostic importance either prior to vascular surgery in the neck region or in patients of intravascular diseases such as arteriovenous malformations or cerebral aneurysms. Therefore, the aim of the study is to bring out 2 variations in the configuration of vertebral artery and their clinical implication. During dissection of thorax of 2 female cadavers, 2 different variants of configurations of left vertebral arteries were observed...

BACKGROUND: Determining an accurate clinical diagnosis for nonarthritic hip pain may be challenging, as symptoms related to femoroacetabular impingement (FAI) or hip instability can be difficult to elucidate with current testing methods. In addition, commonly utilized physical examination maneuvers are static and do not include a dynamic or weightbearing assessment to reproduce activity-related symptoms. Therefore, implementing a dynamic assessment for FAI and hip instability could help to improve diagnostic accuracy for routine clinical examinations of patients with nonarthritic hip pain...

CONTEXT: Osteoporosis is a frequent disease in many populations. The hallmark is fragility fractures, which are harbingers of future fractures, disability, mortality and cost on society. The occurrence increases with age, low vitamin D level and smoking. Smoking rates are high, vitamin D is low and life expectancy is rising steeply in Greenland, as is the need for focus on osteoporosis. We report a case that uses a simple and readily available tool to diagnose osteoporosis at the hospital in Sisimiut, a town of 5000 inhabitants on the west coast of Greenland...

Mucopolysaccharidoses are a group of rare lysosomal storage diseases including a great number of polymorph syndromes, each being related to a particular mutation responsible for a deficiency of glycosaminoglycan degrading enzymes, leading to an accumulation of glycosaminoglycans in tissues. Many of them are diagnosed in children or teenagers and have a severe prognosis because of organ failure, and are consequently usually not seen by the adult rheumatologist. However, some of them have a more progressive presentation, with musculoskeletal symptoms at the forefront and a lifespan that nearly reaches that of the general population...

Human papillomavirus (HPV)-related head and neck squamous cell carcinomas (HNSCC) are radiosensitive tumors and have a better prognosis than the conventional keratinizing HNSCC. Despite extensive radiographic and clinical evaluation in approximately 3% to 5% of patients who present with cervical lymph node metastases, the primary tumor remains occult. The lack of a clinically identifiable primary tumor usually leads to more aggressive therapy, which can result in higher morbidity. Herein, we report a case of a patient with an occult HPV-related HNSCC, diagnosed detecting HPV in a fine needle aspiration cytology (FNAC) of metastatic laterocervical lymph nodes...

AIM: Neonatal clinicians may be asked to review X-ray images when unable to directly access the original image. Transmitting an X-ray image to a smartphone is a technique increasingly being used by clinicians in a number of settings. Minimal data exist on its use in the neonatal setting. Our aim was to compare the ability of neonatal clinicians to correctly diagnose a pneumothorax from a chest radiograph (CXR) viewed on a smartphone, paralleled with the same image viewed on a computer screen...

Morquio syndrome or MPS IVA is a rare type of lysosomal storage disease associated with highly specific dental abnormalities. We present two siblings with enamel hypoplasia and skeletal abnormalities. A diagnosis of mucopolysaccharidosis type IVA was reached based on the clinical, radiographic, and dental findings of the patients. The dental findings are useful diagnostic aid for the early diagnosis of this debilitating disorder.

Posterior reversible encephalopathy syndrome (PRES) is increasingly diagnosed in the emergency department, and medical and surgical intensive care units. PRES is characterized by acute onset of neurologic symptoms in the setting of blood pressure fluctuations, eclampsia, autoimmune disease, transplantation, renal failure, or exposure to immunosuppressive or cytotoxic drugs, triggers known to admit patients to the intensive care unit (ICU). Although the exact pathophysiology remains unknown, there is growing consensus that PRES results from endothelial dysfunction...

Pseudomonas stutzeri is distributed widely in the environment, and occupies different ecological niches. However, it is found in clinically relevant infections as an opportunistic pathogen. Isolation of P. stutzeri from an odontogenic inflammatory cyst is an uncommon microbiological finding that has not been reported to date. In the case presented here, the bacterium was isolated from surgical material obtained from excision of an inflammatory odontogenic cyst located in the tooth 1.2, and presenting with concomitant pulp necrosis...

Workplace bullying is common in health care and has recently been reported in both radiology and radiation oncology. The purpose of this article is to increase awareness of bullying and its potential consequences in radiology and radiation oncology. Bullying behavior may involve abuse, humiliation, intimidation, or insults; is usually repetitive; and causes distress in victims. Workplace bullying is more common in health care than in other industries. Surveys of radiation therapists in the United States, student radiographers in England, and physicians-in-training showed that substantial proportions of respondents had been subjected to workplace bullying...

BACKGROUND: Sometimes patients with a scaphoid fracture, especially in an acute phase of injury, can have normal radiographs and, therefore, initial diagnosis of the scaphoid fracture may be neglected. In this study, we determined the value in of clinical examination and a radiograph in the diagnosis of scaphoid fracture based on the results of a two-week follow-up magnetic resonance imaging (MRI). OBJECTIVES: In this study, sought to assess the value of using both a clinical examination (tenderness of scaphoid tubercle, tenderness of anatomical snuffbox, and compression test) and radiographic imaging in the diagnosis of scaphoid fractures based on the results after a two-week follow-up MRI...

BACKGROUND AND PURPOSE: The 2016 World Health Organization Classification of Tumors of the Central Nervous System includes "diffuse midline glioma with histone H3 K27M mutation" as a new diagnostic entity. We describe the MR imaging characteristics of this new tumor entity in pediatric patients. MATERIALS AND METHODS: We retrospectively reviewed imaging features of pediatric patients with midline gliomas with or without the histone H3 K27 mutation. We evaluated the imaging features of these tumors on the basis of location, enhancement pattern, and necrosis...

OBJECTIVE: Postdural puncture headache (PDPH) is an uncommon sequel of lumbar puncture in children. When conservative treatment with bed rest, hydration, and caffeine are ineffective, epidural blood patches are recommended and are generally effective. The purpose of this report was to highlight that when lumbar epidural blood patches fail to eliminate PDPH, diagnostic evaluation should be performed and alternative treatment sought. CASE REPORT: An unusual case is described of an 11-year-old boy with PDPH, which was successfully managed with a ventral (anterior) epidural blood patch and epidural saline infusion after headache and other symptoms failed to resolve after conservative treatment and conventionally performed blood patches...

Fluoroscopy-guided transbronchial forceps biopsy has a low diagnostic yield in patients with radiographic suspicion of interstitial lung disease. Cryobiopsy has a higher diagnostic yield likely due to preserved lung architecture and larger biopsies; however, there is an increased risk of major airway bleeding and pneumothorax. Simultaneous use of endobronchial balloon blocker allows for containment of bleeding after cryobiopsy to the affected lobe. In the current article we describe use of radial ultrasound in identification of a target lung parenchyma without a major blood vessel adjacent to distal bronchi...

There are numerous sesamoids and accessory ossicles around the foot which can easily be misdiagnosed as fractures. Os subtibiale is a very rare normal variant of the medial malleolus which is usually diagnosed incidentally in routine ankle radiographs. In this report, we present a case series of 3 patients with os subtibiale who were admitted to the emergency department with ankle sprains and misdiagnosed as medial malleolar fractures. We would like to raise awareness to the very rare and usually asymptomatic os subtibiale as a diagnostic pitfall...
