Dr Duncan Schellenberg Patched Patched Link

Introduction

Dr. Duncan Schellenberg, a Canadian plastic surgeon, made headlines in 2019 after a video of him performing a breast augmentation surgery with a patchwork of glued-together implants went viral. The video, which was shared on social media, sparked a wave of criticism and concern among medical professionals and the general public.

The Incident

On August 23, 2019, Dr. Schellenberg performed a breast augmentation surgery on a patient at his clinic in Toronto. During the procedure, he used a combination of saline and silicone gel implants, which he glued together to create a single, larger implant. The video of the surgery, which was recorded by a surgical assistant, showed Dr. Schellenberg applying layers of glue to the implants, creating a patchwork effect.

The Backlash

The video of the surgery sparked widespread criticism and concern among medical professionals, regulatory bodies, and the general public. Many experts questioned the safety and efficacy of using glued-together implants, citing concerns about the risk of implant rupture, capsular contracture, and other complications. dr duncan schellenberg patched

Regulatory Response

The incident prompted an investigation by the Royal College of Physicians and Surgeons of Canada (RCPSC) and the Canadian Medical Association (CMA). The RCPSC and CMA expressed concerns about Dr. Schellenberg's technique, stating that it was not in line with established medical standards.

Consequences for Dr. Schellenberg

As a result of the incident, Dr. Schellenberg faced disciplinary action. In November 2019, the RCPSC revoked his privileges to perform surgery, and he was also required to undergo additional training and education on proper surgical techniques.

The Concept of "Patched"

In the context of Dr. Schellenberg's surgery, "patched" refers to the makeshift technique of gluing together multiple implants to create a single, larger implant. This approach is not a recognized or accepted medical practice and has been widely criticized by medical experts.

Risks and Complications

The use of glued-together implants poses several risks and complications, including:

1. Implant rupture: The glued-together implants are more prone to rupture, which can lead to serious complications, including pain, inflammation, and the need for additional surgery.
2. Capsular contracture: The abnormal scarring that can occur around breast implants can lead to capsular contracture, which can cause pain, discomfort, and distortion of the breast tissue.
3. Infection: The use of glue to attach implants increases the risk of infection, which can lead to serious complications, including sepsis and death.

Conclusion

The incident involving Dr. Duncan Schellenberg and the use of "patched" implants highlights the importance of adhering to established medical standards and best practices. The use of glued-together implants is not a safe or effective approach, and it can lead to serious complications and risks for patients. Medical professionals and regulatory bodies must remain vigilant in ensuring that surgeons adhere to established standards and guidelines to provide safe and effective care for patients. Introduction Dr

Based on the keyword string provided, this appears to be a request for a guide related to Dr. Duncan B. Schellenberg, a prominent figure in the fields of Patched (Patched1/PTCH1) signaling and Hedgehog pathway research.

Dr. Schellenberg (associated with the University of Washington’s Department of Biological Structure) has published seminal work on how the Patched receptor functions. Specifically, his research helped resolve the long-standing debate on whether Patched acts via a "sterile" transport mechanism or protein-protein interactions.

Here is a guide based on the scientific understanding of Dr. Schellenberg’s work on the Patched receptor.

1. The Core Concept: The "Sterile" Hypothesis

Before the research conducted by Schellenberg and colleagues, the mechanism of how Patched inhibited the protein Smoothened (SMO) was a mystery. Dr. Schellenberg's work provided crucial evidence for the Sterol Sensing Model.

• The Old View: It was hypothesized that Patched might be pumping unknown molecules or interacting physically with Smoothened to stop signaling.
• The Schellenberg Contribution: His work demonstrated that Patched acts as a transporter. Specifically, it functions as a "pump" that exports specific sterols out of the cell membrane.

Practical Application

Clinicians applying Schellenberg’s principles will find themselves doing more "oral motor" or tactile-kinetic work than they might with standard phonological clients. This involves: Implant rupture : The glued-together implants are more

• Increasing awareness of tongue tip vs. back of tongue.
• Using metaphorical phonetics (e.g., "Mr. Tongue Tip" vs. "The Back Lift").
• Utilizing visual feedback (tongue depressors, mirrors) to break the "patched" habit.

Critique and Limitations

While the theoretical framework is robust, the practical resources for this specific niche can be scarce. Clinicians often have to adapt Schellenberg’s research papers into therapy materials themselves, as there are few pre-packaged "Schellenberg Protocol" kits available commercially compared to mainstream programs like Hodson’s Cycles.
