Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Summary

Cocaine sniffing can cause air in the epidural space (pneumorachis) and chest (pneumomediastinum) due to lung pressure changes. This case highlights that conservative management is often effective for this rare complication.

Area of Science:

  • Medicine
  • Pulmonology
  • Toxicology

Background:

  • Pneumorachis, or air in the epidural space, typically results from mediastinal air diffusion through intervertebral foramina.
  • Spine trauma or medical procedures can also introduce air into the epidural space.
  • Cocaine use presents unique potential mechanisms for pneumomediastinum and pneumorachis.

Purpose of the Study:

  • To explore the mechanisms linking cocaine sniffing to pneumomediastinum and pneumorachis.
  • To present a case study of a patient experiencing these conditions after cocaine use.
  • To discuss diagnostic and management strategies for this rare presentation.

Main Methods:

  • Literature review on pneumorachis and pneumomediastinum mechanisms.
  • Case report of a 28-year-old male presenting with chest pain post-cocaine sniffing.
  • Diagnostic imaging using computed tomography (CT) scans of the chest.
  • Clinical monitoring and follow-up imaging.

Main Results:

  • Cocaine sniffing can lead to pneumomediastinum and pneumorachis via alveolar rupture from hyper-pressure or wall fragility.
  • The case patient presented with pneumomediastinum, pneumorachis, and subcutaneous emphysema after cocaine use.
  • CT scans confirmed the diagnosis, and the patient stabilized with conservative management.

Conclusions:

  • Cocaine-induced pneumomediastinum and pneumorachis are rare but possible complications.
  • Mechanisms involve increased intra-alveolar pressure or direct alveolar damage.
  • Close monitoring and conservative management are often sufficient, with surgery reserved for severe cases.
