Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Specific Aim of examining wounds microscopically is to attempt to demonstrate the presence of biofilm in chronic wounds and to understand these populations on a cellular level.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Characterizing the surface of the acute wound is important because the characterization can act as a control and can give a standard by which to judge the microscopic pathology observed in chronic wounds.

no treatment

The information obtained by the evaluation of both acute and chronic wounds is pivotal to truly understanding the intercellular tactics used by wound biofilms which work to disrupt host tissue and to evade the host's immune system.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* The subject must be 18 years of age or older.
* The subject must have a full thickness acute or chronic wound. The sampling is restricted to subjects with the presence of a full thickness wound in order to reduce any risk for infection to the subject. Biopsying a wound that is already full thickness should not increase the subject's risk.
* The subject must have no history of coagulopathy
* If the subject's acute wound will be biopsied, the wound must be less than 48 hours old.
* The subject must be a candidate for sharp debridement

Exclusion Criteria

* The subject may not have myelosuppression indicated by a CBC which may include a WBC less than 1500 cells per cubic millimeter, platelet count less than 125,000 per cubic millimeter, or hemoglobin less than 9 g/dL.
* The subject may not be on anticoagulation therapy because anticoagulation therapy increases the risk of bleeding.
* The subject may not have a TCpO2 less than 20 torr. Subjects with low tissue oxygenations may have some risk from biopsy due to their poor ability to heal and, therefore, are excluded.
* The subject may not be pregnant
* The subject's wound must not be in the region of the face, neck, or genitalia
