Acute decompression illness and serum s100beta levels: a prospective observational pilot study
1Australasian College for Emergency Medicine, Western Operations, Western Australia.
Summary
Serum S100beta is not a reliable biomarker for decompression illness (DCI) in recreational divers. This pilot study found no significant elevation in S100beta or Creatine Kinase (CK) levels in patients with acute DCI.
Area of Science:
- Biochemistry
- Neurology
- Diving Medicine
Background:
- S100beta is a calcium-binding protein found in astroglial cells and other tissues.
- Elevated S100beta levels are observed in various neurological conditions.
- No prior research existed on S100beta in recreational divers with decompression illness (DCI).
Purpose of the Study:
- To investigate serum S100beta as a potential biochemical marker for DCI in recreational divers.
- To determine if S100beta levels are elevated in patients diagnosed with acute DCI.
Main Methods:
- Collected venous blood samples from 21 patients treated for acute DCI.
- Analyzed serum S100beta concentration and Creatine Kinase (CK) activity.
- Samples were taken at initial presentation and post-treatment.
Main Results:
- Neither S100beta nor CK levels were significantly elevated above normal population limits in DCI patients.
- No correlation was found between S100beta levels and the presence of acute DCI.
Conclusions:
- S100beta is not a clinically useful serum marker for diagnosing acute DCI.
- Further research is not warranted for S100beta as a DCI biomarker based on these findings.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
