David C Johnson, Robert E Reiter
The ability to image the prostate accurately and better characterize cancerous lesions makes multiparametric magnetic resonance imaging (mpMRI) an invaluable tool to improve management of localized prostate cancer (PCa). Improved risk stratification is warranted given the evidence of significant overtreatment of indolent PCa. mpMRI can more accurately rule out clinically significant PCa in men deciding between surveillance and definitive treatment to reduce overtreatment. mpMRI improves detection of clinically significant PCa, which helps minimize sampling error, a major limitation of the traditional diagnostic paradigm...

INTRODUCTION: Thyroid metastases from colorectal cancer are uncommon and few cases are described in literature. CASE PRESENTATION: A 64-year-old female patient presented with an asymptomatic right cervical nodule with a rapid growth six years after sigmoidectomy for cancer and two years after resection of colorectal lung metastases. Increased CA 19.9 was identified and a thoracoabdominal CT scan revealed the onset of new metastatic bilateral pulmonary lesions. Neck ultrasonography showed a suspicious nodule in the right thyroid lobe, and Fine-needle Aspiration Cytology (FNAC) of the nodule lead to the diagnosis of colorectal cancer metastasis...

OBJECTIVES: The Response Evaluation Criteria in Solid Tumors (RECIST) International Working Group developed criteria for tumor response and progression to standardize radiological assessment in patients receiving chemotherapy in phase 2 trials. However, it is unclear whether the defined percentage change in tumor size and volume reflects true clinical benefit for the patient. The RECIST criteria were designed to improve objectivity in trials, but not to replace clinical decision making...

The frequency of a large pressure signal drift (PDs) caused by pressure wire using optical fibers and its effect on fractional flow reserve (FFR)-based decision-making is not clear. We used pressure wires using optical fibers as "workhorse wires" for 95 consecutive lesions. The wire was normalized at the tip of the guiding catheter just before performing the percutaneous coronary intervention (PCI) and was used without re-normalization until the end of the PCI. The drift value at the end of the procedures was evaluated...

Many surgical techniques are available for the repair of peripheral nerve defects. Autologous nerve grafts are the gold standard for most clinical conditions. In selected cases, alternative types of reconstructions are performed to fill the nerve gap. Non-nervous autologous tissue-based conduits or synthetic ones are alternatives to nerve autografts. Allografts represent another new field of interest. Decision making in the treatment of nerve defects is based on timing of referral, level of the injury, type of lesion, and size of any gap...

INTRODUCTION: The use of fine-needle aspiration (FNA) cytology for the preoperative evaluation of salivary gland lesions is an accepted but, currently, nonstandardized practice. More specifically, cystic major salivary gland lesions are relatively rare and can be very challenging to diagnose on FNA due to low cellularity and an incredibly broad differential diagnosis. The purpose of this study was to investigate the diagnostic utility of preoperative FNA cytology for cystic major salivary gland lesions...

Clinical guidelines are topical systematically developed provisions designed to help the doctor make a decision about a treatment approach in certain clinical situations; they provide information on conducting diagnostic and screening tests, the amount of medical and surgical care, and other aspects of clinical practice. Vestibular schwannomas account for 8% of all intracranial lesions, up to 30% of posterior cranial fossa tumors, and 85% of cerebellopontine angle tumors. The incidence rate of acoustic neuromas is approximately 1 case per 100000 population per year...

REVIEW
S Gerdes, U Mrowietz, U Wagner
Psoriasis and psoriatic arthritis are common disease entities in the daily routine of dermatologists and rheumatologists. The clinical management of the diseases profits tremendously from interdisciplinary contacts and shared decision-making processes. For dermatologists, recognition of early clinical symptoms of inflammatory arthropathies is pivotal. Rheumatologists, on the other hand, are required to make an early assessment of skin and nail changes in patients, since they are important parameters in the clinical classification of inflammatory joint diseases, in particular for the diagnosis of psoriatic arthritis...

BACKGROUND: Traumatic brain injury (TBI) is a leading cause of death and disability in people under 45. Advanced imaging techniques to identify injury and classify severity in the first few hours and days following trauma could improve patient stratification and aid clinical decision making. Traumatic cerebral microbleeds (TCMBs), detectable on magnetic resonance susceptibility weighted imaging (SWI), can be used as markers of long-term clinical outcome. However, the relationship between TCMBs and injury severity in the first few hours after injury, and their natural evolution, is unknown...

PURPOSE: To develop an atlas for oncoplastic surgery (OPS) with template dissection techniques via anatomically ideal incisions for breast conservation surgery. The evolution of breast conservation techniques has evolved from placing an incision directly over the lesion to the incorporation of a thoughtful decision making process utilizing oncoplastic surgical (OPS) techniques to combining OPS with incision placement in anatomically advantageous sites. The high survival rates of breast cancer and effect of breast surgery on quality of life reinforce emphasis of optimal oncologic as well as aesthetic outcome...

OBJECTIVE: The aim of our study was to compare percutaneous vascular interventions (PVI) versus bypass surgeries (BSX) in patients with critical limb ischemia (CLI). BACKGROUND: Previous relevant reviews with limited numbers of included studies did not strictly confine the inclusion criteria to CLI, also involving patients with severe claudication, which may introduce bias in the decision-making of CLI revascularization. Current treatment strategies for CLI still remain controversial...

Quantitative assessments of articular cartilage function are needed to aid clinical decision making. Our objectives were to develop a new electromechanical grade to assess quantitatively cartilage quality and test its reliability. Electromechanical properties were measured using a hand-held electromechanical probe on 200 human articular surfaces from cadaveric donors and osteoarthritic patients. These data were used to create a reference electromechanical property database and to compare with visual arthroscopic International Cartilage Repair Society (ICRS) grading of cartilage degradation...

Breast cancer is the most commonly diagnosed cancer in women in the United States and the second leading cause of cancer death in American women (1). Regular screening mammography starting at age 40 years reduces breast cancer mortality in average-risk women (2). Screening, however, also exposes women to harm through false-positive test results and overdiagnosis of biologically indolent lesions. Differences in balancing benefits and harms have led to differences among major guidelines about what age to start, what age to stop, and how frequently to recommend mammography screening in average-risk women (2-4)...

We propose a computerized framework that, given a region of interest (ROI) circumscribing a lesion, not only predicts radiological observations related to the lesion characteristics with 83.2% average prediction accuracy but also derives explicit association between low-level imaging features and high-level semantic terms by exploiting their statistical correlation. Such direct association between semantic concepts and low-level imaging features can be leveraged to build a powerful annotation system for radiological images that not only allows the computer to infer the semantics from diverse medical images and run automatic reasoning for making diagnostic decision but also provides "human-interpretable explanation" of the system output to facilitate better end user understanding of computer-based diagnostic decisions...

The GATA2 gene codes for a hematopoietic transcription factor that through its two zinc fingers (ZF) can occupy GATA-DNA motifs in a countless number of genes. It is crucial for the proliferation and maintenance of hematopoietic stem cells. During the past 5 years, germline heterozygous mutations in GATA2 were reported in several hundred patients with various phenotypes ranging from mild cytopenia to severe immunodeficiency involving B cells, natural killer cells, CD4(+) cells, monocytes and dendritic cells (MonoMAC/DCML), and myeloid neoplasia...

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imaging localized the lesion to the superficial lobe of the parotid gland, suggesting a neurofibroma. Cosmetic disfigurement and a functional deficit led us to perform complete surgical resection...
