Summary
This service aids medical and surgical inpatients with psychiatric conditions. Rounds reports offer valuable insights for physicians at the medicine-psychiatry interface.
Area of Science:
- Psychiatry and Medicine
- Inpatient Consultation Services
Background:
- Medical and surgical inpatients frequently present with comorbid psychiatric symptoms.
- Effective management requires collaboration between medical and psychiatric teams.
Purpose of the Study:
- To summarize the diagnostic and management discussions from the Massachusetts General Hospital Psychiatric Consultation Service rounds.
- To provide a resource for clinicians working at the intersection of medicine and psychiatry.
Main Methods:
- The Psychiatric Consultation Service conducts twice-weekly rounds.
- Discussions focus on diagnosis and management of inpatients with complex medical/surgical issues and psychiatric conditions.
Main Results:
- Rounds discussions generate practical insights into managing complex cases.
- The service addresses a critical need for integrated care.
Conclusions:
- The Psychiatric Consultation Service provides essential support for hospitalized patients with dual diagnoses.
- Rounds reports are a valuable educational tool for clinicians in medicine and psychiatry.

Hallucinogens and Psychedelics
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains delta-9-tetrahydrocannabinol (THC)...

CNS Stimulants: Psychedelic Agents
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...
Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
An Overview of Psychoactive Drugs
Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...
