PURPOSE: To investigate the blood supply to the nipple areola complex (NAC) on thoracic CT angiograms (CTA) to improve breast pedicle design in reduction mammoplasty. METHODS: In a single centre, CT scans of the thorax were retrospectively reviewed for suitability by a cardiothoracic radiologist. Suitable scans had one or both breasts visible in extended fields, with contrast enhancement of breast vasculature in a female patient. The arterial sources, intercostal space perforated, glandular/subcutaneous course, vessel entry point, and the presence of periareolar anastomoses were recorded for the NAC of each breast...

OBJECTIVE: Correlate serial T2 relaxometry (T2R) values with long term seizure outcome in patients with solitary cerebral cysticercosis (SCC) in order to establish its usefulness as a prognostic marker in these patients. METHODS: Patients with new-onset seizures due to SCC were imaged serially using a pre-determined MRI protocol at enrolment and after 3, 6, 12 and 24months. T2 relaxometry was performed using a dual echo sequence with maps generated manually from the measured image intensities at the level of the lesion...

Transcranial magnetic stimulation focused on either the left anterior supramarginal gyrus or opercular part of the left inferior frontal gyrus has been reported to transiently impair the ability to perform phonological more than semantic tasks. Here we tested whether phonological processing abilities were also impaired following lesions to these regions in right-handed, English speaking adults, who were investigated at least 1 year after a left-hemisphere stroke. When our regions of interest were limited to 0...

BACKGROUND: Vascular Cognitive Impairment (VCI) refers to cognitive dysfunction due to vascular brain injury, as a single cause or in combination with other, often neurodegenerative, etiologies. VCI is a broad construct that captures a heterogeneous patient population both in terms of cognitive and noncognitive symptoms and in terms of etiology and prognosis. This provides a challenge when applying this construct in clinical practice. OBJECTIVE: This paper presents the rationale and design of the TRACE-VCI study, which investigates the clinical features and prognosis of VCI in a memory clinic setting...

INTRODUCTION: Anatomical change of tumor during radiotherapy contributes to target missing. However, in case of tumor shrinkage adaptation of volume could results in an increased incidence of recurrences in the area of target reduction. This study aims to investigate the incidence of failure of adaptive approach and in particular the risk of local recurrence in the area excluded after replanning. METHODS: In this prospective study, LA-NSCLC patients treated with concomitant chemoradiation underwent weekly chest-CT simulation during treatment...

BACKGROUND CONTEXT: Severe adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity requiring surgery to stop curve progression. Posterior spinal instrumentation and fusion with pedicle screws is the standard surgery for AIS curve correction. Vascular and neurologic complications related to screw-malpositioning are concerns in surgeries for AIS. Breach rates are reported at 15.7%, implant-related complications at 1.1% and neurologic deficit at 0.8%. Free-hand screw insertion remains the prevailing method of screw placement while image guidance has been suggested to improve placement accuracy...

Introduction The incidence of renal cell carcinoma (RCC) has been increasing over the past few decades. Simultaneously, due to improved imaging, small renal masses at stage pT1 have been diagnosed more frequently. However, it is known that even small RCCs may recur and metastasize at a late point of time. This study aimed to identify easy-to-assess clinical and histopathological prognostic markers for long-term survival. Patients/Methods We performed a retrospective analysis of patients who underwent surgical treatment of a pT1 RCC in a single centre between 1993 and 2007...

Small bowel adenocarcinoma (SBA) complicating Crohn's disease (CD) is rare and generally found incidentally on surgical specimens. We report our experience in CD-associated SBA observed this last decade in a tertiary referral centre in order to update its incidence, clinical presentation and pathological features. All SBAs diagnosed in patients who underwent surgery for CD between 2006 and 2016 were retrospectively included. Clinico-pathological characteristics were reviewed, and follow-up was updated. SBA was diagnosed in 9 (1...

Central nervous system (CNS) vasculitis (CNS) in systemic erythematosus lupus (SLE) is a rare and challenging diagnosis. We report four cases of CNS vasculitis that occurred 5 to 16 years after the diagnosis of SLE. Magnetic resonance imaging (MRI) detected different features suggestive of CNS vasculitis: enhancement and thickening of the vascular wall, vascular stenosis, ischemic brain lesions and intracerebral haemorrhage unlikely to correspond to other mimic aetiologies. Three patients received combination therapy with glucocorticoids (GC) and cyclophosphamide (CYC)...

BACKGROUND: Optimum cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is essential for the curative treatment of peritoneal carcinomatosis of colorectal origin. At present, surgeons depend on visual inspection and palpation for tumour detection. Improved detection of tumour tissue using molecular fluorescence-guided surgery could not only help attain a complete cytoreduction of metastatic lesions, but might also prevent overtreatment by avoiding resection of benign lesions...
