Summary
A rare form of tuberculosis affecting the ear and mastoid is difficult to diagnose due to non-specific symptoms. The GeneXpert test proved useful for detecting mycobacteria in this challenging paucibacillary case.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Radiology
Background:
- Tuberculosis (TB) rarely affects the otomastoid compartment.
- Diagnosis is challenging due to non-specific symptoms and paucibacillary nature.
Observation:
- A case of aural tuberculosis presented with zygomatic and Bezold abscesses.
- Symptoms were disproportionate to examination findings, mimicking an indolent ear infection.
Findings:
- The patient presented with localized abscesses without other systemic TB symptoms.
- GeneXpert testing was crucial for identifying mycobacteria in this paucibacillary condition.
Implications:
- Highlights the importance of considering tuberculosis in refractory ear infections.
- Emphasizes the utility of molecular diagnostic tools like GeneXpert for early and accurate diagnosis of aural TB.

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...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:12Strategies of Self-Presentation I: Strategic Self-Presentation
230
Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

01:29Processes of Self-Presentation
257
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...

01:21Antipsychotic Drugs: Typical and Atypical Agents
927
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

970
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
