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...
Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
Dark Triad and Person Perception01:29

Dark Triad and Person Perception

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...
Social Loafing01:37

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated, individuals become less...
Nonconscious Mimicry01:13

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.
Confirmation Biases01:31

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Summary
This summary is machine-generated.

Ileal carcinoid tumors can mimic Crohn's disease symptoms, complicating diagnosis. This case highlights the importance of considering carcinoid tumors in the differential diagnosis, especially for older patients presenting with suspected inflammatory bowel disease.

Area of Science:

  • Gastroenterology
  • Oncology
  • Diagnostic Imaging

Background:

  • Carcinoid tumors often present with non-specific symptoms.
  • Differential diagnosis can be challenging due to symptom overlap with inflammatory bowel diseases like Crohn's disease.

Observation:

  • A 57-year-old patient exhibited clinical and radiological signs suggestive of Crohn's disease.
  • The patient was ultimately diagnosed with a carcinoid tumor affecting the terminal ileum.

Findings:

  • Terminal ileum carcinoid tumors can present with symptoms mimicking Crohn's disease.
  • Diagnostic imaging may show features overlapping with inflammatory bowel disease.

Implications:

  • Ileal carcinoid tumors should be included in the differential diagnosis for suspected Crohn's disease.
  • Consideration is particularly important in older patients presenting with these symptoms.
  • This case underscores the need for a broad diagnostic approach in challenging gastrointestinal cases.
