INTRODUCTION: Many countries have developed their own airborne early warning and control (AEW&C) systems for use in surveying their territorial sky in real time. However, a review of the literature suggests that no studies have been conducted to analyze the cervical spine of pilots and air-controllers of AEW&C aircraft. METHODS: The study subjects were 80 pilots and air-controllers of AEW&C aircraft with a period of service of > 1 yr and had data on physical examinations, simple radiographs and functional scores of the axial skeleton, and questionnaires about lifestyle and working conditions...

INTRODUCTION: Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed...

PURPOSE: Parapharyngeal space (PPS) tumors are rare, accounting for 0.5% of all head-and-neck masses. Surgery remains the standard treatment for most cases, including different approaches (cervical approach, parotidectomy, mandibulotomy, transoral/robotic). We report our experience in the management of PPS tumors, aiming to create a surgical algorithm on the base of tumor's radiological and clinical characteristics. MATERIALS AND METHODS: Critical retrospective analysis of patients with PPS neoplasms who underwent surgery at our Institute...

BACKGROUND AND PURPOSE: The Head and Neck Imaging Reporting and Data System (NI-RADS) surveillance template for head and neck cancer includes a numeric assessment of suspicion for recurrence (1-4) for the primary site and neck. Category 1 indicates no evidence of recurrence; category 2, low suspicion of recurrence; category 3, high suspicion of recurrence; and category 4, known recurrence. Our purpose was to evaluate the performance of the NI-RADS scoring system to predict local and regional disease recurrence or persistence...

Tumefactive fibroinflammatory lesions (TFLs) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. TFLs are seen more frequently in males between 10 and 74 years of age. The usual site of involvement is the head and neck region, but rarely the extremities may be involved. Coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosis, sclerosing cholangitis, sclerosing mediastinal fibrosis, and orbital pseudotumors. The etiology of this poorly understood entity remains unknown...

BACKGROUND: Although several morphological abnormalities or variances of the hip joint have been proposed to be associated with hip joint degeneration, few studies have investigated any radiological features in patients with transient osteoporosis of the hip (TOH). The purpose of this study is to evaluate the morphological variances of the hip joint in TOH patients radiographically. METHODS: The TOH group consisted of 31 hips in 31 patients. Age- and gender-matched asymptomatic hips in patients with unilateral osteonecrosis of the femoral head were served as controls...

BACKGROUND: In numerous animal and human studies, it could be detected that in bone augmentation procedures, material's physicochemical characteristics can influence the cellular inflammatory pattern and therefore the integration in the host tissue. Histological, histomorphometrical, and clinical analyses of the integration of the biomaterial in the surrounding tissue are well established methodologies; however, they do not make a statement on volume and density changes of the augmented biomaterial...

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent...

In oncology, biomarkers that describe the characteristics of a malignancy on different levels (clinical, histological, molecular) and the patient's outcome and treatment response are increasingly integrated into the clinical routine. Extensive screening tools, "omics," offer incredible opportunities and vast amounts of data. During the last years, the field of "omics" gained a new promising partner, the "radiomics." Based on radiological imaging, multiple features can be extracted and linked to clinical, genomic, and histopathological data from other sources...

BACKGROUND: Maxillary ameloblastomas are rare and associated with an aggressive course because of the anatomic composition of the maxilla and adjacent structures. The risk factors associated with recurrence were analyzed in this retrospective study. METHODS: Cases of maxillary ameloblastoma reported in a tertiary hospital from 2005 to 2015 were analyzed to identify clinicopathological and radiological factors associated with recurrence using univariate and multivariate Cox regression analyses...

Extramedullary plasmacytomas (EP) are tumours composed by a monoclonal population of plasma cells that arise in extraosseus tissues, comprising <5% of all plasma cell neoplasms. Usually, EP arise in the head and neck region, and the stomach is the second most common location-gastric plasmacytoma (GP). Clinical and radiological manifestations are unspecific and may mimic other tumours like gastric adenocarcinomas, gastric stromal tumours and lymphomas, mainly marginal cell lymphoma (MALT lymphoma) and usually definitive diagnosis is provided by pathological evaluation...

BACKGROUND: Treatment of young, active patients with symptomatic glenohumeral osteoarthritis, excessive glenoid retroversion, and static posterior humeral subluxation is challenging. Correction of glenoid retroversion may lead to centric loading and perhaps recenter the humeral head. We describe the functional and radiologic outcomes after corrective osteotomy of the glenoid in this population of patients. MATERIALS AND METHODS: In this retrospective study, we included 10 shoulders (8 patients) that were observed for a mean of 33...

OBJECTIVE: The availability of new imaging techniques has conditioned an increase in the incidental diagnosis of small nonfunctioning pancreatic neuroendocrine tumors (PNET-NF). The best treatment is controversial, some authors advise a conservative approach in selected cases. Our aim is to analyze the evolution of incidental, small size PNET-NF, treated with clinical follow-up without surgery. METHODS: We performed a retrospective analysis of a prospective database of patients diagnosed incidentally with PNET-NF since November 2007 to September 2015...
