Patent ductus arteriosus (PDA), in which there is a persistent communication between the descending thoracic aorta and the pulmonary artery that results from failure of normal physiologic closure of the fetal ductus (see image below), is one of the more common congenital heart defects.

Epilepsy is the fourth most common neurological disorder and affects people of all ages Epilepsy means the same thing as "seizure disorders" Epilepsy is characterized by unpredictable seizures and can cause other health problems Epilepsy is a spectrum condition with a wide range of seizure types and control varying from person-to-person Public perception and misunderstanding of epilepsy causes challenges often worse than the seizures

What Is Hemodialysis and How Does It Work?
What Is Hemodialysis and How Does It Work? Scott 74 Views • 2 years ago

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.

Anterior Abdomen Wall Abscess
Anterior Abdomen Wall Abscess samer kareem 10,235 Views • 2 years ago

Intra-abdominal abscess continues to be an important and serious problem in surgical practice. Appropriate treatment is often delayed because of the obscure nature of many conditions resulting in abscess formation, which can make diagnosis and localization difficult. Associated pathophysiologic effects may become life threatening or lead to extended periods of morbidity with prolonged hospitalization. Delayed diagnosis and treatment can also lead to increased mortality; therefore, the economic impact of delaying treatment is significant.

Parasite Cleanse
Parasite Cleanse samer kareem 2,924 Views • 2 years ago

Do you need to do a parasite cleanse? Probably... I hear from so many people suffering from symptoms of parasites - severe bloating, cramps, constipation, diarrhoea. A big problem in getting to the bottom of this (pun intended) is that the mainstream medical system really doesn’t have a way to detect, or even find most forms of parasites. They give you drugs for the symptoms, but essentially the parasites aren’t removed during that process.

Spleen Pain
Spleen Pain samer kareem 8,236 Views • 2 years ago

What is the spleen and what causes an enlarged spleen (splenomegaly)? The spleen sits under your rib cage in the upper left part of your abdomen toward your back. It is an organ that is part of the lymph system and works as a drainage network that defends your body against infection. White blood cells produced in the spleen engulf bacteria, dead tissue, and foreign matter, removing them from the blood as blood passes through it. The spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam. But diseases can cause it to swell and become many times its normal size. Because the spleen is involved in many functions, many conditions may affect it.

Deviated nasal septum Surgery
Deviated nasal septum Surgery samer kareem 1,886 Views • 2 years ago

When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing. The additional exposure of a deviated septum to the drying effect of airflow through the nose may sometimes contribute to crusting or bleeding in certain individuals. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both. Treatment of nasal obstruction may include medications to reduce the swelling or nasal dilators that help open the nasal passages. To correct a deviated septum, surgery is necessar
