Venous Malformation in the Breast: Imaging Features to Avoid Unnecessary Biopsies or Surgery.

Venous malformations are now categorised under the broad heading of slow flow vascular malformations. They comprise abnormally dilated venous channels that fail to involute. These may be superficial or deep in location. We describe two cases of venous malformation in breast. Both the patients presented with focal pain in one breast. On mammography, they appeared as equal density well circumscribed soft tissue masses. No sonographic correlate was found on initial ultrasound examination. Subsequent ultrasonography performed by an experienced radiologist with minimal probe pressure revealed dilated veins. On the basis of imaging findings, the diagnosis of venous malformation was established.

Distrust as a form of inequality.

Navigating social hierarchies is a ubiquitous aspect of human life. Social status shapes our thoughts, feelings, and actions toward others in various ways. However, it remains unclear how trust is conferred within hierarchies and how status-related cues are used when resources are on the line. This research fills this knowledge gap by examining how ascribed, consensus-based status appearance, and perceived status appearance impact investment decisions for high- and low-status partners during a Trust Game. In a series of pre-registered experiments, we examined the degree to which participants trusted unfamiliar others with financial investments when the only available information about that person was their socioeconomic status (SES). In Study 1, SES was ascribed. Studies 2 and 3 conveyed SES with visual antecedents (clothing). Across all three experiments, participants trusted high SES partners more than low SES partners. In addition, subjective perceptions of status based on visual cues were a stronger predictor of trust than consensus-based status judgments. This work highlights a high status-trust bias for decisions where an individual's money is on the line. In addition, high-status trust bias may occur simply because of an individual's subjective assumptions about another's rank.

COVID-Associated Sinonasal Mucormycosis: Radiological Pathological Correlation and Prognostic Value of MR Imaging.

Purpose Our aim was to assess the sinonasal magnetic resonance imaging (MRI) features of acute invasive fungal rhinosinusitis (AIFRS) in coronavirus disease (COVID)-associated mucormycosis (CAM) and to correlate these with histopathology and patient outcome in terms of duration of hospital stay and survival at 10 weeks. Methods Twenty patients with histopathologically confirmed sinonasal CAM underwent MRI (including postcontrast T1-weighted and diffusion-weighted imaging). Histopathological findings (presence of coagulative necrosis, granulomatous reaction, and fungal burden) were recorded and all patients were followed up at 6 and 10 weeks. Statistical analysis was done using chi-square test and Fischer's exact test. Results Enhancement patterns seen in our subjects included homogeneous, heterogeneous, and lack of contrast enhancement (LOC), with LOC being the most common (65%). Diffusion restriction was found in 90% patients. Statistically significant correlation was found between LOC pattern and presence of coagulative necrosis ( p -value = 0.007), extent of fungal hyphae ( p -value = 0.047), and duration of hospital stay ( p -value = 0.004). Restricted diffusion was also seen to correlate with a high fungal load ( p -value = 0.007). Conclusion Our study describes the MRI findings of AIFRS in CAM and highlights the imaging features which may be surrogate markers for coagulative necrosis and fungal burden.

Socio-demographic features and quality of life post burn injury.

Introduction: Burn injury is a highly devastating injury accounting for the major cause of disability-adjusted life years (DALYs) lost mostly in developing countries. Physical trauma, body disfigurement, the social stigma associated with injury completely shatter an individual's life. Aim: To study the quality of life among burn injury patients. Methodology: A cross-sectional hospital-based descriptive study was done on 150 burn injury patients. During the initial recruitment from Burns and Plastic Surgery Ward, socio-demographic profile and burn incident-related data were collected, whereas the WHO QoL-BREF tool was applied after 3 months of discharge during a follow-up visit in the outpatient department of Burns and Plastic Surgery to assess the quality of life among subjects. Data were compiled in MS Excel and statistical analysis was done using SPSS 20 version. Results: The study revealed poor quality of life among four domains of QoL; it was most inferior in the psychological domain followed by the physical health domain, environment domain, and social relationship domain. Conclusion: Advancement in the medical field has improved the survival rate in victims although the patients recover from the acute painful phase of physical trauma. However, the psychological and social impacts of injury remain unaddressed leading to a poor QoL. There is a need for an integrated approach for prevention and enhancement of the quality of care for the victims in all four domains of life. More emphasis is needed on rehabilitative care for long-term improvement in the QoL of the affected person.

Congenital Aural Atresia: What the Radiologist Needs to Know?

Congenital aural atresia (CAA) is characterized by hypoplasia or aplasia of external auditory canal associated with auricular deformity. It also embodies a spectrum of temporal bone abnormalities including anomalies of middle ear, ossicles, facial nerve, oval window, round window, mastoid pneumatization, temporomandibular joint and occasionally inner ear and vascular anomalies. The management in such patients is variable and consists of rehabilitative hearing aids or surgical correction depending on various patient factors like associated temporal bone abnormalities, degree of hearing impairment and laterality. Surgical management if planned, depends on the extent of associated temporal bone anomalies and hence necessitates comprehensive knowledge about the normal and abnormal anatomy of these structures. High resolution computed tomography (HRCT) is the optimal investigation which provides required anatomical information and plays a pivotal role in deciding the management strategy. This pictorial review aims to review the spectrum of anomalies involving critical structures in CAA on HRCT along with their clinical significance.

Quantitative Electroencephalographic Markers of Delirium in the Pediatric Intensive Care Unit: Insights From a Heterogenous Convenience Sample.

OBJECTIVE: Little is known about the underlying neurophysiology of pediatric delirium. In adult patients, the sensitivity of EEG to clinical symptoms of delirium has been noted, with a slowing of background activity (alpha) and an increase in slow-wave activity (delta-theta). In this pilot study, the authors extended this investigation to a pediatric cohort. METHODS: In a convenience sample, 23 critically ill children were screened for delirium, using the Cornell Assessment for Pediatric Delirium (CAPD), every 12 hours throughout their pediatric intensive care unit stay as part of standard intensive care unit procedure, and EEGs were performed as part of their clinical care. After hospital discharge, EEGs were reviewed using quantitative analysis, and the maximum delta-alpha ratio (DAR; eyes closed) was derived for each 12-hour period. DAR values were compared between delirious and nondelirious episodes, and the linear relationship between DAR and CAPD was assessed. RESULTS: Higher DARs were associated with episodes of delirium. The DAR also positively correlated with CAPD assessments, with higher DARs relating to higher delirium scores. CONCLUSIONS: Future prospective studies may further investigate this relationship in a more homogeneous and larger sample, and the DAR should be considered to track delirium and assess the effectiveness of therapeutic interventions.

Painful clicking jaw: a pictorial review of internal derangement of the temporomandibular joint.

Temporomandibular joint disorders are a common cause of chronic musculoskeletal pain worldwide. Among these, internal disc derangement is the most frequent type of disorder. Internal derangement is defined as an abnormal positional and functional relationship between the disc and articulating surfaces. Common clinical symptoms include pain and clicking. Imaging plays a key role in diagnosing temporomandibular joint disorders. It is important for the radiologist to detect early imaging signs of internal derangement, thereby avoiding the evolution of this condition to degenerative joint disease. The aim of this article is to familiarise the reader with the spectrum of imaging findings that are encountered at different stages of the disease.
