Burns are classified as first-, second-, or third-degree, depending on how deep and severe they penetrate the skin's surface. First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example.
Most intact aortic aneurysms do not produce symptoms. As they enlarge, symptoms such as abdominal pain and back pain may develop. Compression of nerve roots may cause leg pain or numbness. Untreated, aneurysms tend to become progressively larger, although the rate of enlargement is unpredictable for any individual. Rarely, clotted blood which lines most aortic aneurysms can break off and result in an embolus. They may be found on physical examination. Medical imaging is necessary to confirm the diagnosis. Symptoms may include: anxiety or feeling of stress; nausea and vomiting; clammy skin; rapid heart rate. In patients presenting with aneurysm of the arch of the aorta, a common symptom is a hoarse voice as the left recurrent laryngeal nerve (a branch of the vagus nerve) is stretched. This is due to the recurrent laryngeal nerve winding around the arch of the aorta. If an aneurysm occurs in this location, the arch of the aorta will swell, hence stretching the left recurrent laryngeal nerve. The patient therefore has a hoarse voice as the recurrent laryngeal nerve allows function and sensation in the voicebox. Abdominal aortic aneurysms, hereafter referred to as AAAs, are the most common type of aortic aneurysm. One reason for this is that elastin, the principal load-bearing protein present in the wall of the aorta, is reduced in the abdominal aorta as compared to the thoracic aorta (nearer the heart). Another is that the abdominal aorta does not possess vasa vasorum, hindering repair. Most are true aneurysms that involve all three layers (tunica intima, tunica media and tunica adventitia), and are generally asymptomatic before rupture. The most common sign for the aortic aneuysm is the Erythema nodosum also known as leg lesions typically found near the ankle area. The prevalence of AAAs increases with age, with an average age of 65–70 at the time of diagnosis. AAAs have been attributed to atherosclerosis, though other factors are involved in their formation. An AAA may remain asymptomatic indefinitely. There is a large risk of rupture once the size has reached 5 cm, though some AAAs may swell to over 15 cm in diameter before rupturing. Before rupture, an AAA may present as a large, pulsatile mass above the umbilicus. A bruit may be heard from the turbulent flow in a severe atherosclerotic aneurysm or if thrombosis occurs. Unfortunately, however, rupture is usually the first hint of AAA. Once an aneurysm has ruptured, it presents with a classic pain-hypotension-mass triad. The pain is classically reported in the abdomen, back or flank. It is usually acute, severe and constant, and may radiate through the abdomen to the back. The diagnosis of an abdominal aortic aneurysm can be confirmed at the bedside by the use of ultrasound. Rupture could be indicated by the presence of free fluid in potential abdominal spaces, such as Morison's pouch, the splenorenal space (between the spleen and left kidney), subdiaphragmatic spaces (underneath the diaphragm) and peri-vesical spaces. A contrast-enhanced abdominal CT scan is needed for confirmation. Only 10–25% of patients survive rupture due to large pre- and post-operative mortality. Annual mortality from ruptured abdominal aneurysms in the United States alone is about 15,000. Another important complication of AAA is formation of a thrombus in the aneurysm.
This particular video is intended as a demonstration of a physical exam that may be useful in evaluating a patient with shoulder pain.
It is not intended as a complete instructional video and should not be considered a source of complete physical examination instruction. It is also intended not as a perfect example of a physical exam that would be performed for a patient in clinical practice, but is designed to optimize function and efficiency for a OSCE testing setting.
Instead, it should be treated as a supplement to independent learning using primary Osteopathic Physical Examination instructional resources. Clinical skills are best learned and developed with support from faculty in the context of a complete Osteopathic Medical School Curriculum.
Osteopathic Clinical Skills is a channel dedicated to discussing and exploring Osteopathic Clinical Skills concepts for medical students, residents, and clinicians and presenting them in an easy to understand manner.

What is hemodialysis and how does it work? Who needs it? How do you prepare for it? In the United States, over 30 million Americans have kidney disease, and sometimes, kidney disease progresses to kidney failure or end-stage renal disease. When this happens, you cannot survive unless you have a kidney transplant or some form of dialysis. So today we're going to talk about hemodialysis.
Your kidneys are the two kidney bean-shaped organs that are located in your lower back, or in your flanks. And the kidneys are responsible for filtering out or cleaning your blood. They get rid of excess waste, excess toxins, and excess fluids. If your kidneys stop functioning, then you develop renal failure or end-stage renal disease.
What is Hemodialysis?
Hemodialysis, or blood dialysis, is the filtering of your blood outside of your body. So, if your kidneys stop working properly, the hemodialysis acts as a substitute kidney. Now it's important to note that hemodialysis does not actually correct your own kidney function. It does not fix or treat your kidneys.

What is The Dialyzer?
The dialyzer is actually the filter. It's the main powerhouse of the hemodialysis system, and it is what actually acts as the substitute kidney. In the dialyzer, you have these hollow fibers that run through it, and these fibers are bathed in something called dialysates, or dialysis fluid.
How Often Are Patients Treated With Hemodialysis?
Most patients who are on hemodialysis are on it between three and six hours, about three days a week, especially if they go to a center.
How Does Hemodialysis Work?
So when you are on dialysis, how does your blood get from your body to the hemodialysis machine and then back to your body? Well, it does so through tubes, and those tubes are connected to your access, and we'll talk about access in just a moment. But as far as the tubing, the tubing is connected to your body.
Types Of Hemodialysis Access
Arteriovenous Fistula or AV Fistula
The AV fistula is the gold standard as far as hemodialysis access is concerned because it gives you the most efficient hemodialysis and it is the least likely to be infected.
Arteriovenous Graft or AV Graft
The AV graft is very similar to the AV fistula in that you still have a surgically connected artery and a vein, usually in the arm, but in the case where if you have veins that are rather thin or arteries that are thin and maybe too weak in order to really give you a properly functioning, substantial AV fistula, then the vascular surgeon may opt to add an artificial material in order to make that shunt a little stronger, or little more durable. And so, an AV graft is another option for dialysis access.
Catheter
If you're in a situation where you need temporary dialysis, or if you have acute kidney injury, then you may have a temporary Vascath placed, and it's usually placed in a vein of the neck, the internal jugular vein, or it can be placed in the groin, or in the femoral vein.
Who Needs Hemodialysis Treatment?
How do you know if you need hemodialysis, and when is it time to prepare? Well, if you follow up with your kidney doctor (nephrologist) regularly, he or she will be watching your labs. They'll be able to see those signs of your kidneys not functioning properly.
A flail chest occurs when a segment of the thoracic cage is separated from the rest of the chest wall. This is usually defined as at least two fractures per rib (producing a free segment), in at least two ribs. A segment of the chest wall that is flail is unable to contribute to lung expansion. Large flail segments will involve a much greater proportion of the chest wall and may extend bilaterally or involve the sternum. In these cases the disruption of normal pulmonary mechanics may be large enough to require mechanical ventilation.
Radiosurgery: Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, offer patients a new option for the treatment of lung cancer. The CyberKnife® System is used to treat lung cancer patients who cannot tolerate surgery, have an inoperable tumor, or are seeking an alternative to surgery.
Thoracic outlet syndrome affects the space between the collarbone and first rib (thoracic outlet). Common causes include trauma, repetitive injuries, pregnancy, and anatomical defects, such as having an extra rib. Symptoms include pain in the shoulders and neck and numbness, weakness, and coldness in the fingers. Treatment involves physical therapy and pain relief. In rare cases, surgery may be needed to relieve the compression.
Hirschsprung's (HIRSH-sproongz) disease is a condition that affects the large intestine (colon) and causes problems with passing stool. The condition is present at birth (congenital) as a result of missing nerve cells in the muscles of the baby's colon. A newborn who has Hirschsprung's disease usually can't have a bowel movement in the days after birth. In mild cases, the condition might not be detected until later in childhood. Uncommonly, Hirschsprung's disease is first diagnosed in adults.
A lot of women want to know what type of vaginal discharge is normal during pregnancy, and when you're not pregnant. So let's start out by talking about what's normal when you're not pregnant. It's normal to have about 1/2 teaspoon to 1 teaspoon of whitish, creamy, tannish discharge on most days of your cycle in between periods, with the exception of the time of ovulation. Actually, around the time of ovulation, it's normal to notice the discharge becoming more slippery and clear, almost like egg whites. And this is actually a sign that you can watch for to know when you're ovulating. And if you're seeing this type of discharge and you're trying to have a baby, then you should start to time intercourse with ovulation to increase your chances of conceiving.
