Dissociative Identity Disorder01:30

Dissociative Identity Disorder

57
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Bulimia Nervosa01:30

Bulimia Nervosa

64
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

80
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Learning Disabilities01:25

Learning Disabilities

98
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

24
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

55
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Summary
This summary is machine-generated.

Twiddler's syndrome is a rare complication after neurostimulator or pacemaker implantation. It occurs when the generator twists, causing electrode dislodgement or interruption, which is detectable on X-ray.

Area of Science:

  • Medical Devices
  • Neurosurgery
  • Radiology

Background:

  • Twiddler's syndrome is a rare but severe complication following the implantation of neurostimulators or pacemakers.
  • It arises from the mechanical manipulation of the implanted generator within its subcutaneous pocket.

Purpose of the Study:

  • To highlight the etiology and radiographic findings of Twiddler's syndrome.
  • To emphasize the importance of recognizing this complication for appropriate patient management.

Main Methods:

  • Review of clinical cases and radiographic findings associated with Twiddler's syndrome.
  • Analysis of the mechanism of generator migration and electrode disruption.

Main Results:

  • Twiddler's syndrome involves the twisting of the generator, leading to lead dislodgement or malfunction.
  • Radiographic examination is crucial for diagnosing the dislodged electrodes and abnormal generator position.

Conclusions:

  • Twiddler's syndrome is a preventable complication that requires awareness among implanting physicians.
  • Early diagnosis via X-ray is essential for timely intervention and to prevent further complications.
