Prostate Cancer: A PSMA Scan Predicts Recurrence

“We found that the information we could get from PSMA scanning in patients with newly-diagnosed prostate cancer before surgery was at least as reliable and useful as other information from biopsy, PSA levels, or clinical exam for predicting how patients would do after surgery or other treatment,” says Farshad Moradi, a radiologist at Stanford who co-authored the study.

In December, scientists at Stanford University reported promising findings with a new technology that lights up prostate tumors on specialized imaging scans. The approach relies on a minimally-radioactive tracer that travels the body hunting for cancer cells.

Called 68Ga-PSMA-11, and delivered intravenously, the tracer binds exclusively with a protein called prostate- specific membrane antigen (PSMA). Prostate cancer cells contain far more of this protein on their surfaces than normal prostate cells do. Tumors flagged by 68Ga-PSMA-11 show up on an imaging scan like lit matches in a dark room. Doctors are already using PSMA scans to diagnose early metastatic cancer, and the tracer can also be used to ferry drugs directly into malignant tumors.

MEDICAL REVIEW: ‘SINGLE-PORT ROBOTIC SURGERY’

Freethink – Robotics are helping make minimally invasive surgeries even less invasive. Case in point: single-port robotic surgery, a relatively new type of approach where a robotic system controlled by a human surgeon executes the procedure by making only one incision into the patient.

Although still relatively uncommon, single-port surgery has been gaining momentum in recent years. The benefits are noticeable. Compared to traditional surgery, single-port surgery might leave patients with shorter recovery times, less scarring, and overall better outcomes.

The technique is also transforming how surgeons think about and execute surgery itself. “It’s allowing us to do surgeries differently than we do with [multi-port surgery],” said Michael Stifelman, M.D., director of robotic surgery at Hackensack University Medical Center. “What every patient wants is to get back to their life. Single-port robotics is allowing us to get them to that point more quickly.”

Learn more about the future of single-port surgery in this episode of “Operation: Reimagine Surgery,” a Freethink original series produced in partnership with Intuitive, which created the world’s first commercially available robotic surgery system in the 1990s.

Studies: What Makes For Successful Recoveries

Inflammation is the body’s first line of defense, occurring as droves of immune cells rush to the site of injury or acute illness to make repairs and stem further damage.

When successful, inflammation helps the body survive and heal after trauma. However, when recovery following an inflammatory response goes awry, it signals that damage is still occurring — and the inflammation itself can cause further injury, leading to more-severe illness or even death.

But what differentiates a good inflammatory recovery from a bad one?

A new study, led by researchers at Harvard Medical School and Massachusetts General Hospital, published Aug. 22 in Nature Communications, yields critical clues.

The scientists identified universal features of the inflammatory responses of patients who successfully recovered after surgery or acute illnesses such as COVID-19, heart attack, and sepsis. These features, they discovered, include precise paths that white blood cell and platelet counts follow as they return to normal.

Aging: Degenerative Disk Disease Surgical Options

#DegenerativeDiskDisease is a common disorder linked to aging and years of wear and tear on the spine. Long-term therapies have so far eluded medical science.

LAMINECTOMY

Lumbar laminectomy

Laminectomy is surgery that creates space by removing the lamina — the back part of a vertebra that covers your spinal canal. Also known as decompression surgery, laminectomy enlarges your spinal canal to relieve pressure on the spinal cord or nerves.

This pressure most commonly is caused by bony overgrowths within the spinal canal, which can occur if you have arthritis in your spine. These overgrowths sometimes are referred to as bone spurs, but they’re a normal side effect of the aging process in some people.

Some patients are able to have a same-day laminectomy, which means they do not need to stay in the hospital following surgery and are able to go home to recover. The procedure is performed using minimally invasive techniques resulting in smaller incisions, lower risk of infection and, for many people, a quicker recovery.

SPINAL FUSION

Spinal Fusion, Lower Back

Spinal fusion is surgery to permanently connect two or more vertebrae in your spine, eliminating motion between them. Spinal fusion involves techniques designed to mimic the normal healing process of broken bones. During spinal fusion, your surgeon places bone or a bone-like material within the space between two spinal vertebrae. Metal plates, screws and rods may be used to hold the vertebrae together, so they can heal into one solid unit.

Because spinal fusion surgery immobilizes parts of your spine, it changes the way your spine can move. This places additional stress and strain on the vertebrae above and below the fused portion, and may increase the rate at which those areas of your spine degenerate.

Women’s Health: What Is An Oophorectomy?

An oophorectomy is a surgical procedure where one or both of the ovaries are removed. This procedure can be done through a laparoscopic approach, a vaginal approach, or a laparotomy. Removing both ovaries will cause menopause to begin immediately.

There are many reasons why you may need an oophorectomy. This video provides a brief look at what the procedure is, how it’s done and important things to know.

Knee Injuries: Options For ACL Surgery (Mayo Clinic)

DR. C’S JOURNAL: PAIN FOLLOWING TOTAL KNEE REPLACEMENT SURGERY


Total knee replacement(arthroplasty) is one of the most successful orthopedic operations. Satisfaction rate varies between 75 and 90%. Even so, almost 10% of operated individuals will have anterior knee pain, the most common complication, 1 year after TKR.

I had an even greater appreciation of the knee after reading the following article, which explain the causes of knee pain more adequately than I can, and would be good to read.

With knee replacement surgery, a great deal depends on the technical expertise and precision of the operating surgeon. A rotational error more than a degree or two can be critical, so important is proper tracking of the kneecap in the trochlea, or groove in the leg bone(femur). An imbalance in the pull  of muscles, or a knock knee, (Valgus) angulation of the knee, hip rotation, spinal problems, all can be important in generating pain as you get older.

There are psychological factors too. The knee pain after TKR average is only 1/3 of that suffered before the operation, on average. However if you expect that discomfort will disappear completely, or if your pain threshold is low, or if you have anxiety or depression, you may have more postoperative pain, and  be disappointed with the surgery.

My immediate reason to write this article was the anterior knee pain developing in a friend of mine, 15 years after surgery, at the age of 89. She had polio in childhood, and her right leg was severely affected. This caused her to overuse her left leg, resulting in a TKR 15 years ago. Just recently, she started developing anterior knee pain in the left knee. A thallium scan showed a lot of signal on the inside of the kneecap, most likely indicative of inflammation. She is not enthused about having another operation because of her age., and wondered about other things she might do.

An orthopedic friend of mine suggested that injections of a viscous lubricant might help, if the initial operation did not include resurfacing of the kneecap (patella). I would imagine that eventually the resurfacing of the patella with advanced materials, or perhaps stem cells might help.
I also thought of a special brace with a motor assist for her right leg, but the orthopedist said that this did not work very well in polio patients, who have a weak nerve signal.

Although my friends polio made her TKR almost inevitable, there are things that you can do, or avoid doing, that could help avoid TKR. Activities to reduce include squatting, deep lunging, running (particularly in deep sand), high impact sports, repetitive jumping, and running up stairs. Basketball, football, and volleyball come to mind as regular sports that are risky. Maintaining a healthy weight, controlling blood sugar, stoppage of smoking, avoidance of injury, and regular exercise, particularly walking and swimming ,are things that might help.

Remember that your knees are your wheels and are jewels to protect as you get older.
