Have you ever wondered what the kidney looks like with its parenchyma (functional tissue) removed? Here it is! 😷
.
The renal circulation is composed of a complex network of hundreds of thousands of capillaries, all connected and functions as a system. To isolate the vessels, red plasticizer is pumped through the renal artery. After it sets up, acid is used to dissolve away the tissue to reveal a system of astonishing capillaries.

Here is a closeup view of the glomerulus!
.
The renal glomerulus is an elegant structure that serves as an exquisitely selective plasma filtration unit. The glomerulus has been conserved throughout evolution and has a basic cellular organization common in the primitive kidneys of fishes and amphibious vertebrates to the more advanced kidneys of birds, reptiles, and mammals. The normal development and integrity of the glomerulus are essential for the efficient removal of metabolic wastes without inadvertent loss of vital plasma components such as proteins and blood cells into urine. Intensive research over the years has uncovered the interplay between the different cells that comprise the glomerulus, and the genes that help shape and maintain glomerular integrity.

Concentric hypertrophy of the heart! Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, in which the walls of the organ are thickened and its capacity or volume is diminished.
.
Sarcomeres are added in parallel, as for example occurs in hypertrophic cardiomyopathy.
.
In the heart, concentric hypertrophy is related to increased pressure overload of the heart, often due to hypertension and/or aortic stenosis. The consequence is a decrease in ventricular compliance and diastolic dysfunction, followed eventually by ventricular failure and systolic dysfunction.

An incredibly small heart... in fact this is a fetal heart! ♥️
.
.
.

Interestingly enough, the fetal heart does not have to pump blood to the lungs to pick up oxygen. It does not need a separate pulmonary artery and aorta. In the fetal heart, these two blood vessels are connected by a blood vessel called the ductus arteriosus. After birth, the ductus closes and a separate left pulmonary artery and aorta form. The fetal heart also has an opening between the upper chambers (the right and left atria) called the foramen ovale. It lets blood flow directly from the right atrium to the left atrium during fetal development, but closes after birth. So the ductus arteriosus and the foramen ovale are part of the fetal circulatory system before birth but disappear soon after birth. In most babies, these blood-flow routes naturally close up shortly after birth, when the baby's lungs and cardiovascular system take over. Because the fetal heart has a circulatory system different from the one the baby uses after birth, it may be days or weeks before some congenital heart defects are found. How many weeks old do you think this fetus was at this point of heart development ? Comment below and tag a friend!

A severe case of scoliosis in a 14 year old female, measuring more than |105 degrees. She underwent multilevel osteotomies and single stage fusion to correct the deformity!

An interesting case of polycystic liver/kidney disease! A 51-year-old woman with polycystic liver and kidney disease had undergone renal transplantation 21 years before presentation. She had no evidence of cerbrovascular malformations. Bother her father and aunt also had polycystic kidney disease. After the renal transplantation, her liver had become progressively diseased and enlarged through cystic changes. Early satiety, malnutrition, and abdominal pain necessitated a liver transplantation. The recipient's weight at transplantation was 59 kg. A 9.1-kg liver (white arrow) was removed and replaced with a whole graft that was one tenth the weight of the diseased liver (black arrowhead). A large cyst at the dome of the native liver had to be decompressed (white arrowhead) to allow for access to the recipient's supra hepatic vena cava. She made an excellent recovery and had normal kidney and liver function at 4 years of follow-up.

#repost Diverticuli, seen under colonoscopy. Diverticuli are outpouchings within the wall of the colon. In this image taken under colonoscopy, we see multiple diverticuli within the colonic wall. The issue with diverticuli are: ☝️that they can bleed, causing blood loss in the stool, and ✌️ that they can get infected, causing some serious belly pain and fevers, which we call diverticulitis.
.
Within the wall of the colon, there exists a smooth muscular layer 💪 that contracts to move intestinal products along. Diverticuli are thought to occur when this muscular wall is overly strained, needing to squeeeze 😬 intestinal products through. When does this happen?? Well, diets low in fiber (particularly a high meat and low fiber combo 👊) can lead to particularly tough stools 🙈, increasing intra-colonic pressure and the subsequent risk for diverticuli development. Those on purely plant-based diets for instance, which are inherently higher in fiber content, have a significantly lower incidence of diverticuli. The important point here is to be mindful of fiber intake - 30 grams of fiber a day 🍎🍐🍊 is a great number to shoot for!

An apple a day (or 2 or 3 😄) really does keep the doctor away! 🍏♥️🍏

Amazing view inside of the aorta! .
The aorta is the largest artery in the body, initially being an inch wide in diameter. It receives the cardiac output from the left ventricle and supplies the body with oxygenated blood via the systemic circulation.
.
The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta. It terminates at the level of L4 by bifurcating into the left and right common iliac arteries. Tag a friend who is interested in anatomy! 👨🏽‍⚕️👩🏽‍⚕️

Here is a fairly large laceration to the hand! Immediately upon presentation, a laceration should be evaluated and the bleeding controlled using direct pressure. A patient history should be obtained, including mechanism and time of injury and personal health information. A careful exploration of the laceration should be performed to determine severity and whether it involves muscle, tendons, nerves, blood vessels, or bone. Baseline neurovascular and functional status of the involved body part should be evaluated before repair. In this case, no nerves or tendons were involved, and stitches were used to close the laceration.

Total knee replacement surgery showing the wound being stuffed with a bunch of ANTIBIOTIC BEADS, which dissolves over time and prevents infection!
.
The patient underwent a previous knee replacement that had been infected, spreading all the way down to the distal femur. The follow-up surgery involved a revision of the knee replacement with the femur being replaced with a prosthesis and beads used as a preventive measure.  Knee replacement surgery (arthroplasty) is a routine operation that involves replacing a damaged, worn or diseased knee with an artificial joint.
Adults of any age can be considered for a knee replacement, most carried out between the ages of 60 and 80, with a common reason being osteoarthritis. 
The surgery is usually necessary when the knee joint is worn or damaged to the extent that mobility is reduced and you experience pain even while resting.
There are two main types of surgery, depending on the condition of the knee: a total knee replacement (TKR) – both sides of the knee joint are replaced and partial (half) knee replacement (PKR) – only one side of the joint is replaced in a smaller operation with a shorter hospital stay and recovery period.

Can't get enough of these posts by @MDHealthTips !

#repost This picture shows the difference between a healthy heart and a heart in obesity. Notice how drastically the visceral fat encompasses the organ.
There are essentially ✌️ different ways our bodies store fat: 1) Visceral fat, or the type of fat surrounding internal organs, and 2) Subcutaneous fat, or fat stored just under the skin (e.g. cellulite). Although subcutaneous fat is more visible (🙁), it's actually visceral fat that has been shown to have far more detrimental effects on long-term health, especially in heart and metabolic disease.
To measure your risk of visceral fat related heart disease, use the waist-to-hip ratio.
First, measure the circumference of your hip at its widest part, around the buttocks. Then measure your waist at its smallest circumference, just above the belly button. Divide the waist by the hip measurement to get the ratio:
✔️ Normal = men 0.90 or below, women 0.85 or below.
❌ High risk = men above 0.90, women above 0.85.
Goes without saying the importance of nutrition and fitness on visceral fat, risk of heart and metabolic disease, and overall well-being 💪🔥 Follow @MDHealthTips for more!
