Immunoglobulin G4-related disease (IgG4-RD), recognized only recently as a single diagnostic entity, is a chronic inflammatory condition of unknown etiology. The diagnosis of IgG4-RD relies heavily on histopathological analysis and the correlation of histology findings with clinical, serological, and radiological data. CD4+ T and B cells, including IgG4-expressing plasmablasts, constitute the major inflammatory cell populations in IgG4-RD and are believed to cause organ damage and tissue fibrosis. Patients with IgG4-RD, who have active, untreated disease, exhibit marked expansion of IgG4-secreting plasmablasts in the blood...

INTRODUCTION: Major Trauma Centres (MTCs) should ideally have all key surgical specialities on site. This may not always be the case since trauma is only one factor influencing speciality location. The implications of this can only be understood when the demands on specific specialities are established and this is not well documented. We investigated surgical speciality demand by quantifying the frequency and urgency of surgical trauma interventions. PATIENTS AND METHODS: Data on adult trauma admissions for a UK MTC were retrieved from the UK Trauma Audit and Research Network for a 2-year period and analysed to establish the frequency and urgency of surgical interventions...

E. N was a 48-year-old man referred from a peripheral hospital to the Maxillofacial unit of Ahmadu Bello University Teaching Hospital, Zaria, on account of 1-year history of left-sided jaw pain and swelling, particularly after meal. The conventional plain radiograph of the jaws appeared normal as there was no opacity of soft tissue or calcific density visualized. Sialography revealed an oval-shaped filling defect in the dilated left Wharton's duct, which could suggest radiolucent calculus. Ultrasound scan showed the lesion as a brightly echogenic mass surrounded by anechoic clear fluid (saliva), casting posterior acoustic shadow...

Diagnostic imaging is essential in dentistry. Doses range from low to very low, benefits to patients can be immense, and safe techniques are well known but widely ignored. Doses range from very low with properly executed intraoral, cephalometric, and panoramic imaging to higher than multidetector computed tomography with cone-beam computed tomography. Benefits are substantial: imaged dental disease, often obscured from direct vision by size and anatomy, can pose a mortal threat to the patient. Additionally, imaging is often central in planning complex dental procedures...

INTRODUCTION: Florid cemento-osseous dysplasia (FCOD) is a rare, benign, slow growing, multifocal fibro-osseous tumour originating from the periodontal ligament. The lesion is characterised by regular bone-structure replacement with fibrous tissue and dysplastic bone. The initial characteristics of FCOD, depending on localisation, resemble those of periapical lesions of inflammatory origin, potentially leading to misdiagnosis. In the absence of infection signs, the treatment of choice is conservative therapy with antibiotics and regular follow-up examinations...

A 58-year-old patient with a history of intravenous use of denosumab was referred to the department of oral and maxillofacial surgery with inadequate recovery after a series of extractions. During physical and radiological examination, several sites of exposed necrotic bone with purulent discharge were seen, and the maxilla appeared fractured at the level of Le Fort 1. Treatment consisted of intravenous administration of antibiotics with consecutive sequestrectomy of the maxilla under general anaesthesia. While Medication Related Osteonecrosis of the Jaw (MRONJ) is most commonly seen in patients treated with bisphosphonates, in the past decade, it has become apparent that other types of medication, most notably denosumab, can cause comparable disorders...

Introduction: The lingula is used for identifying the site for injection of local anesthetics and for excision of nerve in facial neuralgia. The relationship between lingula and lingual nerves may aid in risk associated with an impacted third molar. Due to its connection to nerve and vascular structures, the study of the lingula provides important information related to oral and maxillofacial surgical procedures, such as the sagittal split ramus osteotomy and the intraoral vertico-sagittal ramus osteotomy carried out to correct dento facial deformities...

Sonography is a simple, inexpensive, and non-invasive diagnostic modality. Although tissues behind bony structures and deep tissues are not delineated, sonography can depict superficial soft tissues very clearly. In the head and neck region, however, it has not yet been used widely, as the anatomical structures are complicated, and considerable experience is needed both to perform an examination and to make a diagnosis. To perform examinations efficiently, operators must be familiar with the sonographic system in use, and take images at standard planes...

Dental cone-beam computed tomography (CBCT) received regulatory approval in Japan in 2000 and has been widely used since being approved for coverage by the National Health Insurance system in 2012. This imaging technique allows dental practitioners to observe and diagnose lesions in the dental hard tissue in three dimensions (3D). When performing routine radiography, the examination must be justified, and optimal protection should be provided according to the ALARA (as low as reasonably achievable) principles laid down by the International Commission on Radiological Protection...

BACKGROUND: Oral and maxillofacial radiology became the ninth dental specialty recognized by the American Dental Association (ADA) in 1999. This came about following the discovery of X-rays by Wilhelm Conrad Roentgen in 1895 and, 14 days later, the application of X-rays to making dental radiographs by Otto Walkhoff. The purpose of this narrative study was to review the evolution of oral and maxillofacial radiology as a dental specialty in the USA and its recognition as a program of training by the West African College of Surgeons...
