Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

1.5K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Equilibrium and Balance

5.2K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Dissociative Disorders01:27

Dissociative Disorders

205
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

296
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Dissociative Amnesia01:21

Dissociative Amnesia

210
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

543
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Subdural Hematoma Presenting as Psychogenic Nausea.

David C Fipps, Elisabet Rainey

    Journal of Psychiatric Practice
    |September 16, 2021
    PubMed
    Summary

    Medically unexplained nausea in an elderly man was initially misattributed to psychogenic causes. A subdural hematoma was discovered, emphasizing the need for broad differentials in diagnosing unexplained symptoms.

    Area of Science:

    • Neurology
    • Geriatrics
    • Medical Diagnostics

    Background:

    • Psychogenic nausea is a term for nausea without clear medical pathology, often linked to psychiatric factors, though this distinction is evolving with DSM-5 criteria.
    • The concept of psychogenic symptoms persists in clinical practice, particularly for medically unexplained conditions.

    Observation:

    • A 74-year-old man presented with nausea initially presumed to be psychogenic following a negative medical evaluation.
    • New tremors were attributed to a benzodiazepine taper.
    • The development of focal neurological deficits prompted further investigation.

    Findings:

    • A computed tomography scan revealed a subdural hematoma.
    • Neurosurgical intervention (evacuation and drainage) successfully resolved the patient's symptoms.

  • Subdural hematomas, often caused by venous tearing, can lead to mass effect and ischemia, presenting with various symptoms including nausea.

    • Implications:

    • This case underscores the critical importance of maintaining a comprehensive differential diagnosis for all medically unexplained symptoms.
    • Close monitoring for evolving symptoms is essential, even when initial assessments suggest a psychiatric or benign etiology.
    • Prompt neurosurgical evaluation can be life-saving in cases of subdural hematoma presenting with neurological deficits.
