The results of previous studies are inconsistent in regard to the relationship between the Iowa Gambling Task (IGT), working-memory (WM), and executive tasks, and whether these cognitive processes could be considered as mechanisms underlying a decision-making deficit. Moreover, the relationship between the IGT and executive measures is examined based on a limited number of executive tasks, within different populations showing diffuse damage. In addition, there are fewer studies carried out within control participants, with those studies also being inconclusive...

Pulmonary atresia (PA) and ventricular septal defect (VSD) can occur in a variety of ways, from simple valve atresia to a condition in which circulation to the pulmonary bed occurs through collateral arteries separated from the aorta and there are no real pulmonary arteries, or they are present but hypoplastic. The size of the pulmonary arteries and concomitant complex cardiac lesions are important in making decisions about treatment and correctional alternatives. While complete correction surgeries in the style of a correction of tetralogy of Fallot are performed in simpler cases, many very invasive procedures are also performed and the resulting quality of life is very variable...

Stroke is a major cause of morbidity and mortality worldwide, and effective treatment requires rapid diagnosis and recognition of relevant vascular lesions. In this review we will discuss the usefulness and versatility of computed tomography angiography in the setting of stroke, be it ischemic or hemorrhagic, minor or disabling. Furthermore, we also highlight how we use computed tomography angiography in decision making in transient ischemic attacks, acute disabling ischemic stroke, and hemorrhagic stroke.

PURPOSE: Traumatic thoraco-lumbar spine fracture spine with a concomitant blunt aortic injury is uncommon but potentially a fatal association. Our aim was to clarify: morphology of spinal fractures related to vascular damages and vice versa, diagnostic procedures and decision-making process for the best treatment options for spine and vessels. METHODS: We enrolled 42 cases culled from the literature and five personal ones, reviewing in detail by AO Spine Classification, Society of Vascular Surgery classification and Abbreviated Injury Scale for neurological evaluation...

The incidence rates of cutaneous melanoma in non-Hispanic whites show an increasing tendency with age. While uveal melanoma in general is a rare disease, representing only 4% of all melanomas with an incidence rate of 0.6 per 100 000, it is still the most frequent malignancy of the eye. Synchronous occurrence of ocular and cutaneous melanoma is an exceptional rarity, due to the distinct genetic background of the diseases. We report the case of a 80-year-old man who underwent total excision of a cutaneous melanoma in 2008...

Numerous studies have addressed the predictive value of pathology findings from the Oxford Classification. Whether this influences treatment choice has not been determined. We evaluated patients with IgA nephropathy who were immunosuppressed and correlated our findings with both clinical and histological features as per the Oxford Classification. This was a retrospective observational study of 45 patients who had biopsy-proven IgA nephropathy with a mean follow-up of 2.6 years. Primary outcomes were time to end-stage renal disease (ESRD) or a 50% rise in serum creatinine...

Coronary artery disease (CAD) is a major cause of death worldwide. It is significantly important to assess the coronary lesion and its pathophysiological relevance comprehensively. Coronary computed tomography angiography (CTA) or myocardial perfusion imaging alone suffers from some limitations in the evaluation of CAD. Through the integration and spatial colocalization of complementary morphological and functional information, the results of published hybrid single-photon emission computed tomography (SPECT)/CTA studies in patients with CAD are promising for detecting functionally relevant coronary artery lesion and evaluating the relationship between diseased coronary artery, coronary artery anomaly, myocardial bridging, or coronary calcification and myocardial ischemia...

Objective Mesenchymal stem cells (MSCs) are a promising cell-based therapy treatment option for several orthopedic indications. Because culture expansion of MSC is time and cost intensive, a bedside concentration of bone marrow (BM) aspirate is used as an alternative. Many commercial systems are available but the available literature and knowledge regarding these systems is limited. We compared different point-of-care devices that concentrate BM (BMC) by focusing on technical features and quality parameters to help surgeons make informed decisions while selecting the appropriate device...

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature...

Background Head and neck surgical pathology has been shown to be prone to histopathologic diagnostic error that can adversely impact patient care due to inappropriate management. Sinonasal tumors, in particular, present a diagnostic challenge given the relative rarity and diversity in histology and thus may have higher rates of discordant histology. Objective The purpose of this study is to determine the rate of discrepancy between preoperative and postoperative diagnoses of sinonasal tumors. Methods Retrospective chart review was performed on 52 patients treated for sinonasal tumors between January 2013 and December 2016...

BACKGROUND: Vestibular schwannomas and meningiomas account for the great majority of lesions arising in the cerebellopontine angle (CPA). In this report, we present a case of glioneuronal heterotopia, also known as glioneuronal hamartoma, arising from the VIII cranial nerve, which is an extremely uncommon lesion. Important radiologic and surgical aspects are reviewed, which may help in early recognition and intraoperative decision making when these lesions are encountered.

OBJECTIVE:   To present recommendations for the diagnosis, management, outcomes, and return to play of athletes with superior labral anterior-posterior (SLAP) injuries. BACKGROUND:   In overhead athletes, SLAP tears are common as either acute or chronic injuries. The clinical guidelines presented here were developed based on a systematic review of the current evidence and the consensus of the writing panel. Clinicians can use these guidelines to inform decision making regarding the diagnosis, acute and long-term conservative and surgical treatment, and expected outcomes of and return-to-play guidelines for athletes with SLAP injuries...

OBJECTIVE It is relatively unusual for pediatric CNS tumors to be disseminated at presentation, and the literature on the clinical features, management, and outcomes of this specific group is scarce. Surgical management in this population is often challenging, particularly in the presence of hydrocephalus. The authors present their recent experience of treating pediatric CNS tumors that were disseminated at presentation, and they compare these lesions with focal tumors. METHODS The authors performed a retrospective review of prospectively collected data on children presenting to a tertiary center between 2003 and 2016 inclusive...

The increasing interest and use of cartilage repair procedures in the knee has led to a better understanding of when and how chondral lesions should be treated. Nonetheless, there are still key areas where we lack understanding and need better data to guide clinical decision making. One of these areas is how to manage lesions of the tibia, particularly when they occur in conjunction with the more commonplace lesions of the femoral condyle. In this setting, a tibial chondral lesion may reflect a bigger clinical problem-a "bipolar defect" or more advanced joint disease-"established osteoarthritis...

OBJECTIVE: A well-documented effect of focal ventromedial prefrontal cortex (vmPFC) damage is a deficit in real-world decision making. An important aspect of this deficit may be a deficiency in "internal consistency" during social decision making-that is, impaired congruence between expressed preferences versus actual behavioral choices. An example of low internal consistency would be if one expressed the desire to marry someone with impeccable moral character, yet proceeded to marry someone convicted of multiple felonies...

Increasing attention is being paid to the assessment of white matter properties and its structural connectivity, both in healthy subjects and patients with cerebral lesions. Within this framework, new neurocognitive models based on hodological properties have been developed under a connectomic perspective in order to explain substrates and cognitive mechanisms related to cerebral functions such as language and memory. With regards to focal and drug-resistant epilepsy conceived as a network disorder, new insights in terms of structural connectivity have led to significant advances in epilepsy research, concerning fundamental research (neurocognitive mechanisms of plasticity) and clinical application (optimization of decision making for curative surgery)...

Due to its superior sensitivity, breast MRI (bMRI) has been established as an important additional diagnostic tool in the breast clinic and is used for screening in patients with an elevated risk for breast cancer. Breast MRI, however, is a complex tool, providing multiple images containing several contrasts. Thus, reading bMRI requires a structured approach. A lack of structure will increase the rate of false-positive findings and sacrifice most of the advantages of bMRI as additional work-up will be required...

Value-based decision making (VBDM) is a principle that states that humans and other species adapt their behavior according to the dynamic subjective values of the chosen or unchosen options. The neural bases of this process have been extensively investigated using task-based fMRI and lesion studies. However, the growing field of resting-state functional connectivity (RSFC) may shed light on the organization and function of brain connections across different decision-making domains. With this aim, we used independent component analysis to study the brain network dynamics in a large cohort of young males (N = 145) and the relationship of these dynamics with VBDM...

PURPOSE OF REVIEW: This article reviews the clinical presentation, diagnostic evaluation, and management of immune-mediated myelopathies. RECENT FINDINGS: The discovery of several neural autoantibodies and their antigenic targets has revolutionized the investigation and treatment of immune-mediated myelopathies. Detection of these serologic biomarkers can support or establish a diagnosis of an autoimmune myelopathy, and, in the case of paraneoplastic syndromes, indicate the likely presence of an underlying malignancy...
