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...

Increasing number of patients with clinically suspected venous thromboembolism is referred to radiological departments for definitive diagnosis. A simple assay to exclude the diagnosis and avoid radiological examinations is needed. We have reported correlations between D-dimer and prothrombin fragment 1 + 2 measured in plasma and urine. To further develop an analysis based on urine, more understanding of thrombin generation in these patients is needed. The aim of this study was to compare ex vivo thrombin generation with in vivo markers in plasma and urine in patients with and without venous thromboembolism...

Two recently reported phase III randomised control trials (RCTs) have resulted in the registration of two new systemic therapies for advanced soft tissue sarcoma. Both of these trials' designs were informed by phase II data that guided the selection of sensitive STS diagnoses, enabling the demonstration of benefit in certain subtypes. A number of other phase III trials reported in the last 18 months have seemingly fit into a recurrent pattern of failure-promising efficacy signals in earlier phase studies being lost in the survival follow-up of large, highly heterogeneous cohorts...

BACKGROUND: Osteopetrosis is a rare hereditary metabolic bone disorder characterized by generalized skeletal sclerosis caused by a defect in bone resorption and remodelling. Infantile autosomal recessive osteopetrosis is one of three subtypes of osteopetrosis and the most severe form. The correct and early diagnosis of infantile osteopetrosis is important for management of complications and for future genetic counselling. Diagnosis is largely based on clinical and radiographic evaluation, confirmed by gene testing where applicable...

OBJECTIVE: There has been an increasing movement worldwide to create systematic screening and management procedures for atypical injury patterns in children with the hope of better detecting and evaluating nonaccidental trauma (NAT). A legitimate concern for any hospital considering implementation of a systematic evaluation process is the impact on already burdened hospital resources. We hypothesized that implementation of a guideline that uses red flags related to history, physical, or radiologic findings to trigger a standardized NAT evaluation of patients <4 years would not negatively affect resource utilization at our level II pediatric trauma center...

Primary Sjögren syndrome (pSS)-related interstitial lung disease (ILD) involved about 10-20% of patients. In 20% of cases, ILD can be diagnosed before pSS; anyway, few studies have investigated the frequency of ILD as the first clinically relevant manifestation of pSS, generally referred to retrospective studies. Aim of our prospective study was to describe prevalence, clinical, serological, and instrumental features of non-sicca onset pSS patients with interstitial lung involvement. During a period of 48 months, all consecutive patients diagnosed as pSS were enrolled...

INTRODUCTION: Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic encephalopathic state associated with reversible cerebral vasogenic edema. Seizures are a common clinical presentation in PRES, however its electroencephalographic and radiologic pattern correlation is limited in this subset of patients. The aim of this study is to analyze the origin of electrographic dysfunction according to the radiologic pattern in patients with PRES and seizures. METHODS: We retrospectively identified 46 cancer patients who developed PRES and seizures at The University of Texas MD Anderson Cancer Center between January 2006 and June 2012...

Immunoglobulin G4-related disease (IgG4-RD) is a recently defined condition characterized by inflammatory tumefactive lesions in various organ systems. IgG4-RD is a clinical and radiological diagnosis of exclusion and requires the presence of specific histopathological criteria for diagnosis. A 50-year-old man presented to an outside hospital with a 3-month history of progressively worsening back pain and symptoms of pleurisy, nasal crusting, and hematochezia. Radiological workup revealed an epidural-paraspinal mass with displacement of the spinal cord, destruction of the T5-6 vertebrae, and extension into the right lung...

Non-malignant oesophageal diseases are critical to recognize, but can be easily overlooked or misdiagnosed radiologically. In this paper, we cover the salient clinical features and imaging findings of non-malignant pathology of the oesophagus. We organize the many non-malignant diseases of the oesophagus into two major categories: luminal disorders and wall disorders. Luminal disorders include dilatation/narrowing (e.g. achalasia, scleroderma, and stricture) and foreign body impaction. Wall disorders include wall thickening (e...
