A cornea transplant, also called keratoplasty, is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power. A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.

A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus. Each of your knees has two menisci — C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.

Dr. Ebraheim’s educational animated video describing the anatomy and associated injuries of the knee joint.
Disrupted quadriceps
•Patient is unable to actively extend the knee.
The most common cause of ACL ruptures:
•Traumatic force being applied during twisting motion.
•Side stepping or landing from a jump.
Patient complains of:
•Immediate pain
•Knee giving way
•Swelling
Aspiration of the knee
•If aspiration of the knee joint shows evidence of blood within the joint there is 75-80% chance of ACL and meniscal injury.
Lachamn’s test- ACL knee exam
•Knee is flexed at 30 degrees.
•ACL tear of the knee is identified by pulling on the tibia and examining the frontward motion of the lower leg in comparison to the upper leg.
Radiological exam – ACL
•MRI of the knee joint shows bone lesions or bruising associated with tears of the ACL. Injury is found in the typical location; middle of the femoral condyle and posterior part of the tibia laterally.
Posterior cruciate ligament tear (PCL)
•Common cause of injury is a bent knee hitting a dashboard in a car accident.
Tibial Sag Test –PCL knee exam
Quadriceps active test-PCL knee exam
•The examiner stabilizes the leg of the patient and then the patient is asked to actively contract the quadriceps muscle.
•The tibia is seen actively reduced from the posterior subluxed position.
Lachman’s test-PCL knee exam
•Knee is bent 20-30 degrees.
•The posterior drawer test is carried out while the patient is in a supine position and the knee is flexed to 90 degrees.
•The amount of translation of the tibia relative to the femur is observed.
The dial test is performed while the patient is in the supine or prone position and both knees are in 90 and 30 degrees of flexion. More than 10 degrees of external rotation indicates significant injury.
Common meniscal tears
Symptoms include
•Knee pain
•Pain with straightening the knee
•Swelling
•Locking
•Weakness

Cigarette contain tobacco that is very harmful but vaporizers does not contain tobacco. ... The most basic difference between vaping and cigarette usage is that cigarettes require combustion. You need fire to light a cigarette. On the other hand, vaping requires electricity and creates vapor.

Overweight does not necessarily equal unhealthy. There are actually plenty of overweight people who are in excellent health (1). Conversely, many normal weight people have the metabolic problems associated with obesity (2). That’s because the fat under the skin is actually not that big of a problem (at least not from a health standpoint, it’s more of a cosmetic problem). It’s the fat in the abdominal cavity, the belly fat, that causes the biggest issues (3). If you have a lot of excess fat around your waistline, even if you’re not very heavy, then you should take some steps to get rid of it. Belly fat is usually estimated by measuring the circumference around your waist. This can easily be done at home with a simple tape measure. Anything above 40 inches (102 cm) in men and 35 inches (88 cm) in women, is known as abdominal obesity. There are actually a few proven strategies that have been shown to target the fat in the belly area more than other areas of the body.

Most of us have taken a sex education class or two. We know what condoms are supposed to be used for. Whether or not people use condoms every time they are necessary is a totally different story. You were probably taught the necessary but embarrassing lesson of how to put a condom on by the visual aids your sex education teacher provided. Of course, these tactics are a little more modern, so depending on how old you are, you may not have learned the basics of condom use until after high school. Yes, condoms are a pretty smart invention and they’re pretty safe to use. They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners. However, with all the things we know about condoms, there’s still so much we don’t know. Here are 10 facts about condoms that are just as interesting as the condoms themselves.

Compartment syndrome can develop in the foot following crush injury or closed fracture. Following some critical threshold of bleeding and/or swelling into the fixed space compartments, arterial pulse pressure is insufficient to overcome the osmotic tissue pressure gradient, leading to cell death. The complicating factor is related to the magnitude of the force of the crush injury. The amount of swelling or bleeding has to be sufficient to impair arterial inflow, while not being of sufficient magnitude to produce an open injury, which decompresses the pressure within the affected compartments. When the injury is open, we then attribute the late disability primarily to the crushing injury to the involved muscles.

An enlarged spleen may cause: No symptoms in some cases. Pain or fullness in the left upper abdomen that may spread to the left shoulder. Feeling full without eating or after eating only a small amount from the enlarged spleen pressing on your stomach. Anemia. Fatigue. Frequent infections. Easy bleeding.

What is vascular access? What are the different types of accesses for hemodialysis? Does vascular access require surgery?

The majority of all headaches are tension related headaches. The blockage of blood circulation along with contraction/shortening of muscles is what causes this condition. This simple technique can take away most tension related headaches in seconds.

Leopold's Maneuvers are difficult to perform on obese women and women who have hydramnios. The palpation can sometimes be uncomfortable for the woman if care is not taken to ensure she is relaxed and adequately positioned. To aid in this, the health care provider should first ensure that the woman has recently emptied her bladder. If she has not, she may need to have a straight urinary catheter inserted to empy it if she is unable to micturate herself. The woman should lie on her back with her shoulders raised slightly on a pillow and her knees drawn up a little. Her abdomen should be uncovered, and most women appreciate it if the individual performing the maneuver warms their hands prior to palpation. First maneuver: Fundal Grip While facing the woman, palpate the woman's upper abdomen with both hands. A professional can often determine the size, consistency, shape, and mobility of the form that is felt. The fetal head is hard, firm, round, and moves independently of the trunk while the buttocks feel softer, are symmetric, and the shoulders and limbs have small bony processes; unlike the head, they move with the trunk. Second maneuver After the upper abdomen has been palpated and the form that is found is identified, the individual performing the maneuver attempts to determine the location of the fetal back. Still facing the woman, the health care provider palpates the abdomen with gentle but also deep pressure using the palm of the hands. First the right hand remains steady on one side of the abdomen while the left hand explores the right side of the woman's uterus. This is then repeated using the opposite side and hands. The fetal back will feel firm and smooth while fetal extremities (arms, legs, etc.) should feel like small irregularities and protrusions. The fetal back, once determined, should connect with the form found in the upper abdomen and also a mass in the maternal inlet, lower abdomen. Third maneuver: Pawlick's Grip In the third maneuver the health care provider attempts to determine what fetal part is lying above the inlet, or lower abdomen.[2] The individual performing the maneuver first grasps the lower portion of the abdomen just above the symphysis pubis with the thumb and fingers of the right hand. This maneuver should yield the opposite information and validate the findings of the first maneuver. If the woman enters labor, this is the part which will most likely come first in a vaginal birth. If it is the head and is not actively engaged in the birthing process, it may be gently pushed back and forth. The Pawlick's Grip, although still used by some obstetricians, is not recommended as it is more uncomfortable for the woman. Instead, a two-handed approach is favored by placing the fingers of both hands laterally on either side of the presenting part. Fourth maneuver The last maneuver requires that the health care provider face the woman's feet, as he or she will attempt to locate the fetus' brow. The fingers of both hands are moved gently down the sides of the uterus toward the pubis. The side where there is resistance to the descent of the fingers toward the pubis is greatest is where the brow is located. If the head of the fetus is well-flexed, it should be on the opposite side from the fetal back. If the fetal head is extended though, the occiput is instead felt and is located on the same side as the back. Cautions Leopold's maneuvers are intended to be performed by health care professionals, as they have received the training and instruction in how to perform them. That said, as long as care taken not to roughly or excessively disturb the fetus, there is no real reason it cannot be performed at home as an informational exercise. It is important to note that all findings are not truly diagnostic, and as such ultrasound is required to conclusively determine the fetal position.

Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. It also plays a key role in the development of atherosclerotic lesions.Nov 22, 2016

Upper gastrointestinal bleeding (sometimes upper GI, UGI bleed, Upper gastrointestinal hemorrhage, gastrorrhagia) refers to bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. In fact, the proportion of UGIB cases caused by peptic ulcer disease has declined, a phenomenon that is believed to be due to the use of proton pump inhibitors (PPIs) and H pylori therapy. Duodenal ulcers are more common than gastric ulcers, but the incidence of bleeding is identical for both.

Penile implants are devices placed inside the penis to allow men with erectile dysfunction (ED) to get an erection. Penile implants are typically recommended after other treatments for ED fail. There are two main types of penile implants, semirigid and inflatable.

What causes rheumatic fever? Rheumatic fever is not an infection itself, but rather the result of an untreated strep infection. When your body senses the strep infection, it sends antibodies to fight it. Sometimes, these antibodies attack the tissues of your joints or heart instead. If the antibodies attack your heart, they can cause your heart valves to swell, which can lead to scarring of the valve "doors" (called leaflets or cusps). Who is at risk for rheumatic fever? Fewer than 0.3% of people who have strep throat also get rheumatic fever. Rheumatic fever is most common among children aged 5 to 15, but adults may have the condition as well. Doctors think that a weakened immune system may make some people more likely to get rheumatic fever. And, although antibiotic medicines have reduced the number of cases of rheumatic fever in developed countries, there are still thousands of reported cases. What are the symptoms of rheumatic fever and how is it diagnosed? Symptoms of rheumatic fever usually begin 1 to 6 weeks after you have had a strep infection. They are Fever Joint pain or swelling in your wrists, elbows, knees, or ankles Small bumps under the skin over your elbows or knees (called nodules) A raised, red rash on your chest, back, or stomach Stomach pain or feeling less hungry Weakness, shortness of breath, or feeling very tired Your doctor will begin by doing a throat culture to find out if you have a strep infection. Then, your doctor will use a stethoscope to listen to your heart. He or she will also look for nodules on your joints. Sometimes, blood tests, chest x-rays, or an electrocardiogram (ECG or EKG) may be needed for a more definite diagnosis. How is rheumatic fever treated? Rheumatic fever must be treated right away. If you have a sore throat that lasts longer than 3 days, or if you have a fever and headache along with your sore throat, you should see your doctor for a throat culture. Even if you do not have a sore throat but have a fever and a skin rash, this could also mean a strep infection, and you should get tested. Remember rheumatic fever can result from an untreated strep infection, so it is very important to treat the infection before it leads to a worse condition.
