Q. Can 3-D printing be used for creating artificial hips and knees for joint replacement?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Absolutely! 3-D printing technology has already been used to create a number of medical implants, such as artificial hips and knees for joint replacement surgery. This is a rapidly advancing field, and the potential for further applications in healthcare is immense.
In fact, 3-D printing can be used to make custom designed hip and knee replacements that are tailored specifically to an individual patient's anatomy. Using these personalised implants offers many advantages – they fit more securely than traditional implants, improving stability; they result in quicker healing times; and they have the potential to minimise postoperative complications. Additionally, 3-D printed prosthetics don’t require the same costly moulds or tools needed by traditional manufacturing processes, making them much more cost effective overall.
3-D printing is also being explored as a way to improve other types of medical devices. For example, researchers at Vanderbilt University recently created an implantable device using layers of carbon nanotubes printed onto flexible plastic substrates – this type of implant could help restore nerve signals in patients with spinal injuries or paralysis. Similarly, researchers at Princeton University have developed soft robot actuators made from 3-D printed hydrogel materials – these could be used for drug delivery systems or even surgical robotics!
Clearly there are some exciting applications for 3-D printing in the world of medicine – with further advances in the technology we can only expect it will become even more widely used across a variety of different treatments and procedures.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
