Understanding Deception01:14

Understanding Deception

Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...
Deindividuation00:57

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
Masking and Demasking Agents01:19

Masking and Demasking Agents

EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...
Self-Presentation01:25

Self-Presentation

Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...
Processes of Self-Presentation01:29

Processes of Self-Presentation

Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or conventions...
Impression Management Techniques I: Managing Appearances01:29

Impression Management Techniques I: Managing Appearances

Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

Summary
This summary is machine-generated.

Bilateral orbital cellulitis, characterized by swelling and bulging eyes, can be an early indicator of widespread cancer metastasis in patients with a history of treated malignancies. This rare presentation highlights the importance of thorough investigation in recurrent or metastatic disease.

Area of Science:

  • Oncology
  • Ophthalmology
  • Medical Imaging

Background:

  • A 32-year-old woman with a history of treated rectal adenocarcinoma presented with acute bilateral periorbital edema.
  • The patient had undergone surgery and chemotherapy six months prior, with initial negative metastasis workup.

Observation:

  • The patient rapidly developed bilateral axial proptosis, chemosis, and diminished vision within a week.
  • Examination revealed sluggish pupillary reactions and restricted extraocular movements. Systemic examination indicated poor nutritional status with elevated inflammatory markers.

Findings:

  • Computed tomography (CT) of the orbit and brain confirmed metastasis to the frontal bones and orbits.
  • Further investigations revealed concurrent liver and lung metastasis.

Implications:

  • This case underscores that bilateral orbital cellulitis can be an unusual presenting sign of systemic metastasis in patients with previously treated malignancies.
  • Prompt recognition and investigation are crucial for identifying advanced metastatic disease, even with seemingly localized symptoms.
